Hiring is a series of legal acts to easily achieve the purpose of profit or establishment of a company through a job offerer’s selection of the best talent among job applicants, so it is bound to be a very wide and important area in employment. However, the employment sector is also an area where the employer's freedom of hiring has been relatively widely recognized, unlike the labor law system which is traditionally designed to protect workers' rights and regulate employers' responsibilities with a focus on other labor relations. In other words, despite the importance of the hiring process, it was difficult to see the job offerer as an object of legal discipline unless through the lens of discrimination under the Anti-Discrimination Act or abuse of the right to freedom of employment.However, as ‘fair hiring’ has recently become an issue nationwide in Korea, the need for restrictions on ‘freedom of hiring’ has been continuously emphasized in the political and legal areas, and the ‘Fair Hiring Procedure Act’ is establishing its status as a de facto labor law. On the other hand, due to limitations in the purpose of the ‘Fair Hiring Procedure Act’, the need for law-related amendments is being emphasized.While it is important to seek countermeasures for related revisions to the law, if it is possible to improve legal effectiveness without legal revision, it will be important to first review measures to ensure implementation and effectiveness within the current legal system. A representative example is the preparation and recommendation of the ‘standard form’.Accordingly, Article 5 of the ‘Fair Hiring Procedure Act’ allows the Minister of Employment and Labor to determine “standard forms of basic examination materials and recommend job offerers to use them.” The minister may prepare a standard application form and recommend its use. Therefore, based on the current standard form, it will be possible to improve legal effectiveness by reflecting the information to be included in form, compatibility with other laws and regulations, and other improvements.This study reviews the “standard forms of basic examination materials” currently recommended by the Ministry of Employment and Labor to uncover matters that need to be additionally considered in the standard form. In addition, plans to ensure the legal performance and effectiveness of the fair hiring system are reviewed based on the relationship and consistency with other laws and regulations.

생산요소를 시설요소와 작업요소로 구분할 수 있다. 이때 작업요소라 함은 인력 또는 기계력등의 생산활동에 동력을 공급하는 요소를 의미한다. 물자는 이러한 생산요소에 의해 가공되어 제품으로 된다. 이 논문은 작업요소의 최적분배와 시설규모의 적정수준을 결정하는 것을 문제의 대상으로 한다. 기업운영의 궁극적인 목표는 기존 생산시설과 가용작업요소를 활용함으로써 변동하는 수요에 대응한 적절한 생산정책을 통하여 최대의 이익을 도모하는 것이다. 이 논문은 일정한 생산시설규모에 대하여 작업요소 투입량이 변할 수 있고 그에 따라 생산량도 동시에 변하는 생산체계에서 다음의 세가지 문제를 해결하도록 하였다. (1) 시설규모가 일정할때 작업요소 투입량의 적절한 조정 (2) 가용작업요소의 양이 제한되어 있을때 최적시설규모 및 작업요소 투입량의 결정 (3) 수요량이 일정할때 최적시설규모 및 작업요소 투입량의 결정. 이러한 문제들을 해결하기 위한 기법으로서는 선형계획법, 동적계획법, 스케쥴링이론, 대기행렬이론, 재고관리이론, 미시경제학 및 CPM/PER 등이 사용되어 왔다. 본 논문에서는 동적계획법을 이용하여 모델을 수립하였다. 이 논문에 제시한 모델에서 작업요소 투입량의 결정에 필요한 계산단계의 수는 가동할 생산기계의 대수와 일치한다. 그리고 계산의 양을 줄이고 그 감소된 계산단계 안에서 항상 최적해를 구할 수 있다는 이론적 근거와 방법을 제시하였다. 계산의 편의상 전자계산기를 사용하였다. 가상적인 데이타를 사용하여 모델에 적용하여 본 결과 일정한 시설규모에 대하여 작업요소 투입량이 변할 수 있는 경우에는 이 모델이 이용가치가 충분히 있다는 결론을 얻었다.

Recent advances in motion capture makes it possible to construct natural motions in real time. In motion capture method, rotations of each joints are captured from the real human's motions and stored in the computer, and these data are fed to the virtual agent or human model to animate their body motions. Because motion captured data doesn't accomplish general goal position, motion variation technique that edits motion captured data is needed in order to form goal-directed motion. The ultimate objective of this thesis is to develop a method to generate the realistic human motion when the goal of the body's control point is specified. The main difference between our objective and general motion capture technique, is that we are interested in goal-directed motion while others just try to show the motions without goal specified. In this thesis,we develop two motion variation techniques that automatically modifies motion captured data and generates goal-directed motion. We define behavior profile that shows the pattern of human action and this behavior profile is modified such that the resulting motion achieve the specified goal. And experiment was done to show the effectiveness of these technique using hand as a control point.

The purpose of this thesis is to provide the guideline to employee who develop and implement the effective security system under the client/server computing environment. The three step approach is presented in this research. It is named as three-A approach for implementing security system under the client/server computing environment. The first step is the administrative control that security policy is established under the general computing environment in the organization. The second is the architectural control that security policy is established on the specific computing environment, for example client/server computing environment. The last is application control that the above policy is implemented on the real programming environment. These three steps are gradual relationship that the latter steps are influenced by the former steps. Therefore, the whole steps can be implemented with the consistency. With the method that classify the non-sensitive parts concerning the computing environmental change (administrative control and application control) and the sensitive part (architectural control), the ability coping with the computing environmental changes for the organization will be improved. This approach will give the rapid, effective and efficient process, and the lower cost for implementing security system for the organization. To evaluate the avalibility of this reaserch, K company's case is analyzed. The K company was implemented client/server computing system, two or three years ago.

Nowadays, the concept of 'interaction' has been emphasized in the area of design of consumer products, communication devices, and computer systems. Users can communicate or use a product through various interactions between the system and users. The multi-modal functions of a product are providing diverse ways of interactions including visual, auditory and tactile modalities. However, since the design guidelines for creating good interface design haven't been developed sufficiently, it is difficult for designers to collect the information of multi-modal resources, and to construct the way of integrating multi-modalities for a specific product. There is, therefore, a need for developing a systematic study on the interaction design in order to understand the effectiveness of multi-modal interfaces and to maximize the interactivity between the system and users. The goal of this study is to establish guidelines of developing multi-modal interface design systematically, and to propose a new interface design process by two approaches: cognitive and experimental. Through a cognitive approach, this study investigated the characteristics of human-system interactions and the information processing model. Through the literature review, the multiple-resource theory and the modality compatibility have been emphasized. The former reveals that the spatial process and verbal one in the working memory do not interfere each other. The latter suggests that the composition of stimulus-response are dependent on the task. On the basis of these background studies, the taxonomy of modality and guidelines for effective interaction design are proposed. For an experimental approach, a simulation tool called 'MIDS(Multi-modal Interface Design Simulator)' was developed. It consists of 'object library', 'modality composition module', 'entity arrangement module', and 'test module'. The concept of MIDS is to make virtual rapid prototypes by selecting and editing interface designs from the library, and developing creative ideas. By using MIDS, designers can make several multi-modal prototypes and choose better one by simulating the whole interactions. By using the object-library which is extracted from the currently used interfaces within products, designers can develop interface design prototypes easily without programming.

In the present work, the flash atomization mechanism has been studied experimentally focussing mostly on the two-phase effluent flashing mode and a mechanistic model on the atomization process has been constructed to predict the size distribution of drops. In experiments, both the internal flow and external flow patterns (that is, the flow pattern before and after the discharge) were considered simultaneously. The flow pattern inside the nozzle was visualized and the void fraction was measured from photographs of the internal flow by using transparent nozzles. External flow (spray) patterns were also photographed to examine the atomization process and to obtain the spray angle data. Drop sizes were measured by using the light scattering method. It was confirmed that the atomization process after the discharge is governed by the internal flow pattern. The internal flow pattern changes from bubbly flow to slug flow, and then to annular flow with increase of the degree of superheat. However, at the injection pressure above 0.3 MPa, the flow pattern is almost the bubbly flow. Bubble formation/growth becomes more vigorous with increase of the superheat, which results in smaller and uniform drop sizes, and a wide spray angle; especially, the size and number density of bubbles at the nozzle exit are the most important parameters which determine the atomization process. To predict the size and number density of bubbles at the nozzle exit, the one-dimensional two-fluid model along with the vapor generation model by Riznic and Ishii has been used. The atomization process is composed of three steps; bubble breakup, formation of ligaments, and breakup of the ligaments by the aerodynamic drag. In the present atomization model, the mechanical energy is assumed to be conserved when the bubbly two-phase jet is converted into a drop (spray) flow through the disintegration process. Adelberg's model has been adopted to describe the disintegration process of ligaments. Mean drop size predicted by the model is in general agreement with the experimental results in the range of the dimensionless superheat above 0.4. It can be concluded that, except for the low superheat range, the mean drop sizes and flow rates(or mass flux) are predictable to a certain extent with the present mechanistic model once the injection condition and the nozzle geometry are given. Further improvement on the ligament breakup model is needed to predict the spray angle and the spatial distribution of drops reasonably.

In the present experimental study, the flow behavior within a semi-closed two-phase natural circulation loop was examined with an emphasis placed on the role of the expansion-tank line resistance. The loop is composed of the heater, riser, condenser and the down-comer sections and the expansion tank. Water was used as the working fluid. Heat flux, inlet subcooling and inlet-, exit- and expansion-tank- restrictions were taken as the controlling parameters. The circulation modes were examined by measuring the circulation rate(heater-inlet velocity), liquid velocity through the expansion-tank line, void fraction at the riser, heater inlet and outlet temperatures and the loop pressure. Six circulation modes of loopwise natural circulation were identified. They are the single-phase(liquid) circulation, periodic circulation(A), two-phase continuous circulation and periodic circulations(B), (C) and (D). Among these modes, single-phase and two-phase continuous circulations exhibit no significant oscillations and are considered to be the stable operation modes. The single-phase natural circulation is the unique feature observed with the semi-closed loop. Periodic circulation (A) is characterized by the regular occurrence of the large two-phase flow carry-over with the single-phase(liquid) circulation mode between them. Hence, the large amplitude oscillations are induced. Periodic circulation (B) is featured by the flow oscillations with the continuous boiling inside the heater section, and is considered to be the density wave oscillation. Periodic circulation(C) also occurs with the continuous boiling, but with its period being much shorter than that of periodic circulation(B), and is considered to be the manometric oscillation. On the other hand, in the mode of periodic circulation(D), the continuous boiling is still maintained but with the longer period and the larger amplitude of oscillations than those in periodic circulation(B). Periodic circulation(D) is considered to be the pressure drop oscillation. The circulation rate increases and then decreases with increasing of the heat flux. Parametric study shows that the increases of the flow restrictions at the heater inlet and at the expansion-tank line and the decreases of the exit-restriction and the inlet subcooling broaden the range of the two-phase continuous circulation mode. Unlike the analytical prediction, the excursive instability was not identified with the semi-closed loop because the liquid inventory can not be changed easily due to the flow restriction at the expansion-tank line.

An experimental study was conducted to examine the effect of the flow patterns inside the mixing chamber on the atomization performance of the effervescent atomizers. The mixing chamber has the rectangular cross section (8 mm x 2 mm) and made of transparent acrylic plates for flow visualization. The parameters considered were the air/liquid ratio(ALR), injection pressure, and the nozzle orifice diameter. Three different flow regimes were observed: bubbly, annular and intermittent flows. In the bubbly flow regime, the drops are formed through the processes of the bubble expansion and the ligament breakup. On the other hand, in the annular flow regime, the liquid annulus is disintegrated into fine drops by the aerodynamic force exerted by the core gas flow. In the intermittent flow regime, the bubble-expansion/ligament-breakup and the annulus-disintegration modes appear alternatively. The correlations representing the transition criteria between the flow regimes were proposed based on the drift flux model. The bubbly-to-intermittent flow transition was well predicted by determining the maximum void fraction for the stable bubbly flow. Due to the entrance effect, the maximum void fraction turned out to be 0.37 in the present case. The criterion of the intermittent-to-annular flow transition was determined from the force balance between the shear stresses at the wall and the interface for the vertical liquid annulus. The proposed correlations for the flow regime transitions agree satisfactorily with the experimental results. At the same time, the drop sizes were measured by using the image processing technique. Different drop size correlations were proposed pertinent to each flow regime. In the bubbly flow regime, it was assumed that a portion of the mechanical energy concerned with the bubble expansion was consumed to atomize the two-phase mixture. On the other hand, in the annular flow regime, a correlation type for the airblast atomizers was adopted but with taking account of the liquid film thickness and the relative velocity between the phases. For the intermittent flow regime, the correlations for the bubbly and the annular flow regimes were interpolated with a weighting factor as a function of ALR taken into account. The proposed correlations represent the experimental results mostly within $ pm 20$%.

Recently, local and global environmental affairs have changed the business environment. Although that change provides the firm not only threats but also opportunities, few manufacturers utilize these opportunities. With this background we accomplish a descriptive analysis on the adaptation of quality management framework in the green strategy development. In the first, we develop a useful conceptual framework for analyzing green strategy of the business, and describe some cases of the proactive strategy. From these cases, we find the validity of the proactive response. As an implementation framework for the proactive response, we suggest the adaptation of quality management framework. We analyze similarities and differences between quality and environmental affairs in the managerial perspective. In spite of much similarity, we find critical differences due to externality of environmental activities. Considering these differences, we extend the principles of quality management framework and suggest some guidelines. Through this analysis, we address that proactive response could be the best choice for the manufacturers to achieve their competitive advantage. In addition to the result, we suggest that government should set a scheme that can eliminate the externality of environmental activities, i.e. the labeling system for the manufacturing process similar to the energy efficiency labeling system.

Slug flow regime is more broaden than the others in microchannels comparing with flow of conventional channels. Moreover, flow pattern is different according to wettability of surface in microchannels. Generally, bubbles in the slug flow regime are lubricated by liquid film in hydrophilic microchannels. However, bubbles are not lubricated by liquid film in hydrophobic microchannels. So, triple-lines are generated at the interface of the bubble. And the non-lubricated bubbles made higher pressure drop than the lubricated bubbles due to the moving of the triple-line. In previous researches, the pressure drop of triple-line is affected by following parameters.; channel diameter, dynamic contact angle, fluid property. And, dynamic contact angle is affected by following parameters.; static contact angle, superficial velocity, fluid property. Namely, channel diameter, static contact angle, superficial velocity, fluid property have influence on the pressure drop of the triple-line in micorchannels. To understand effect of the parameters, experiments were conducted with various channel diameters(2.076, 1.555, 1.018, 0.763, 0.546 mm), superficial velocity(0.01～0.4 m/s), fluids(water, 1, 5, 10% ethanol-water). Increasing superficial velocity, and decreasing channel diameter, and ethanol mole fraction, the pressure drop of triple-lines was increased. Comparing with previous researches(Jiang et al., Bracke et al, Seebergh et al.), the pressure drop of triple-line in this study was overestimated. In order to understand this cause, dynamic contact angle was compared between this study and previous researches, because it is the dominant dependent parameter of the pressure drop of triple-lines. In previous researches, dynamic contact angle is correlated with universal relations. Universal relation is consisted of static contact angle and capillary number. Universal relation has constraints according to dominant forces acting on interface shape. For example, the universal relation of Jiang et al. is available when dominant forces are only interfacial and viscous force. Also, the universal relation of Bracke et al. and Seebergh et al. is available when dominant force are interfacial, viscous, and gravitational force. However, in this study, dominant forces acting on interface shape were interfacial, viscous, and inertial force. Owing to different dominant forces, dynamic contact angle predicted by previous researches was underestimated. therefore pressure drop of triple-lines was underestimated comparing this study's. So, in this experimental region (0.0001≤Ca≤0.001, 0.01≤We≤0.1, 68°≤θS≤110°), the corrected universal relations was proposed. New proposed correlation predicted dynamic contact angle in 5% error. In addition, pressure drop of triple-lines based on the proposed correlation was predicted in 26% error.

The major objectives of this thesis are (1) to disclose Hispanic*s differences from Whites in purchasing behavior for microwave oven through a survey in Detroit area (2) and to provide Korean companies with differentiated marketing approaches to target the Hispanics in U.S. microwaves market based on the outcomes of this research. Support was found for the following hypotheses : (1) ''Hispanics own more U.S. national brand microwaves than Whites do.'' (2) ''Hispanics are more dependent on TV or radio in obtaining the information about the consumer electronics than Whites are.'' (3) ''Hispanics prefer the mass merchants or discount stores in purchasing microwaves more than Whites do.'' (4) ''Hispanics prefer the white color microwaves more than Whites do.'' Evidence was weak for the following hypotheses: (1) '' Hispanics are more dependent on the brand name in purchasing microwaves than Whites are.'' (2) ''Hispanics are more dependent on the price in purchasing microwaves than Whites are.'' (3) ''Hispanics show lower awareness of the brand of A Electronics than Whites do.'' (4) ''Hispanics spend more time watching, listening to or reading Spanish media than mainstream media.'' (5) '' Hispanics show more influence of female in purchasing microwaves than Whites do.'' The outcomes of this research suggest that marketing strategy for Hispanic market should be conducted starting with densely populated metropolitan area, communicating mainly by Television or Radio, placing differentiated products to their favorite distribution channels. The findings, however, should be interpreted with caution since this research has several limitations in sampling methods. Further research with more elaborated methodology and theory is suggested and encouraged.

Environmental problem is a major and urgent issue facing the earth and its people. Many firms in Korea also have a growing commitment to assure environmental responsibility for all of their operations. This trend is driven partly by market demands for green products and partly by changes in international standards and regulations. However, there is little research on the behavioral analysis of environmental management in Korea. This study examines the behavior of environmental management in the Korean firms and the factors affecting that behavior. The main objectives of this study are as follows: 1) What are the elements of the behavior of environmental management? 2) What are the relationships between the elements of the environmental management behavior and the influencing factors such as top management involvement in environmental management and resource ability? 3) What are the relationships between the elements of the environmental management behavior and the environmental performance? And what are the contingent factors affecting these relationships? Based on the previous literatures on the quality management and management strategy, 8 elements of the behavior of environmental management were derived such as : i) employee participation in environmental management, ii) environmental training, iii) environmental audit, iv) management & improvement in environmental facilities, v) provision against emergencies, vi) resource reutilization, vii) linking with suppliers, viii) public relations of environmental management. Also the factors affecting the behavior of environmental management such as top management involvement in environmental management and resource ability were identified. A field study was undertaken to test hypothesized relationships and data were collected from 42 Korean firms. Correlation analyses, Fisher's Z test were employed to test hypotheses, and ANOVA and t-test were conducted for further analyses. The major findings of this study were as follows: 1) Top management involvement in environmental management is significantly correlated with employee participation in environmental management, environmental training, environmental audit, management and improvement in environmental facilities, and linking with suppliers. 2) Technical ability is significantly correlated with environmental audit, management and improvement in environmental facilities, and provision against Emergencies. Financial capability is also significantly correlated with environmental training, environmental audit, and management & improvement in environmental facilities. 3) All behaviors of environmental management except resource reutilization are significantly correlated with environmental performance. 4) Firm's industrial characteristics and product characteristics partly affect the relationships between the behavior of environmental management and the environmental performance 5) Additional statistical analyses show that environmental policy and the environmental department also affect affirmatively the behavior of environmental management Finally, some managerial implications and limitations of this study were described and future research directions were suggested.

Now a days, environmental issues are the most important problem in the national and global issues. These concerns are without exception to the military activity. In fact, environmental affects from the military activity are have studied in many fields and few nations have efforted to minimize these affects. With this background, we accomplish a descriptive analysis on the green strategy framework in the defense management. In the first, we develop a conceptual framework of defense green strategy, and describe some cases of the proactive strategy. We analyze similarities and differences between firm and defense environmental management. From this analysis, we find critical differences due to basic aim. Considering these differences, we suggest some guidelines and references to apply the Defense PPBEES. Through this analysis, we address that proactive response could be the effective and efficient choice for the military. Additionally, we recommend that military must begin to participate in the nation environmental security, and must develop useful programs and alternatives to balance national security and environmental priorities.

The purpose of this thesis is to examine the effects of individual characteristics and perceived organizational climate on performance in view of comparative study among Korea, China, Malaysia and Indonesia. Three individual characteristics(self-efficacy, locus of control, and work values) and five dimensions of perceived organizational climate(autonomy, innovation, trust, cohesiveness, and pressure) are constructed through literature reviews. A field syudy was undertaken in five factories to examine the hypothesized relationships among the variables. Both individual characteristics and perceived organizational climate determine the individual performance(internal motivation, job satisfaction, organizational commitment, and perceived performance), and especially the patterns of individual characteristics and perceived organizational climate are also closely related to the individual performance. The thesis provides implications for global manager such as what type of individual characteristics should be focused on when selecting employees in different cultures and what kind of organizational climate should be created to increase individual performance.

Nowadays, environmental issues are highlighted in the national and global business strategy and policy areas. These concerns can be applied to the management of military activities. This concept come from the notion that environmental security can take great parts in the national security. Also much of the literature on environment pollution in relation to weapon systems is being reported. Therefore, the Korean military have to develop their own environmental strategy which contribute to achievement of national security based on environmental soundness. Our study is intended to raise awareness and provide effective guidance to the WSAM(weapon systems acquisition management) activities for pollution prevention, which have significant role in environmental protection. We deduce military environmental strategy through SWOT analysis. From the results, we can suggest environmentally sound WSAM and incentive policy alternatives to develop environmental technology of domestic defense industry. Next, we suggest a practical program to environmental management of Korean military. The key of environmentally sound WSAM is that the acquisition management have to consider not only product performance and schedule, but also environmental impacts. We show the environmentally sound WSAM is effective by EMS based on ISO 14000 regulations which are conducted within a structured management system, and pollution prevention technologies which are induced from defense industry. Also, we show that an incentive scheme to develop defense industry's environmental technology can be implemented as a perfect Markov equilibrium of the inducing game.

The peer review system is usually used to evaluate research proposals and scientific articles that are submitted for funding and publication respectively. As jobs and careers of researchers are at stake by a result of a peer review evaluation, it is not surprising that the effectiveness and fairness of the system are matters of great concern. Despite the apparent importance of peer review in influencing funding decisions, and despite growing criticism of alleged deficiencies and biases in peer review systems, not very many empirical studies have been done. Moreover funding institutions would rarely question the validity of their procedures and even when they do they do not publish the results. Scientifically small countries, for example Korea, have adopted the peer review system from the developed countries without probing it to find out whether it is appropriate for their situation, although it is argued that the traditional peer review system is inadequate and probably dangerous for such countries because of the domination of personal relations and politics. Thus there is great need to examine its workings and unintended sideeffects of peer review in scientifically small countries. This study focuses on the peer revierw processes of research proposals for funding. The main objectives of this study are as follows: (1) to identify biases and the factors influencing the evaluation outcome of peer reviewers in assessing research proposals. (2) to measure the degree of the evaluation errors (leniency tendency and halo effects) and to find out their affecting factors. (3) to inquire into the factors having influence on the interreviewer agreement and relability. (4) to measure applicants' reaction to the peer review system and to examine its influencing factors. (5) to assess the potential effectiveness of blind review and to inquire into the factors influencing author recognition of reviewers in blinded research proposals. Eighty-four hypotheses were generated and tested using two kinds of data, one collected from a questionnaire survey of 1,098 reviewers and 476 professors who applied for research funding from the Core Research Support Program(CRSP) of the Korea Science and Engineering Foundation(KOSEF) in the areas of mathematics, physics, biology, computer science, and electrical engineering during fiscal year 1996, and the other acquired from the data base of evaluation scores of their research proposals. Correlation analyses, path analyses, moderated regression analyses, t-tests, and multiple discriminant analyses were employed to test the hypotheses. The major findings of this study are as follows: (1) There were high correlations between reviewer ratings and the following characteristics of 1. the applicants: prestige rank of current university, prestige rank of undergraduate school graduated, nation of Ph.D. training, professional age, academic recognition, KOSEF funding history, and experience in helping KOSEF, 2. the research proposals: research stage. innovativeness, and mainstream/anti- mainstream, 3. the reviewer-applicant relationship: difference of prestige ranks of current university between a reviewer and an applicant, degree of familiarity, perceived similarity, and liking, and 4. the reviewer-proposal relationship: similarity of research areas. Also, reviewer ratings and the previous scientific performance of the applicants had significant influence on funding decisions. (2) The following characteristics of the reviewers had significant correlations with leniency tendency: accountability to the review, need for affiliation, satisfaction with KOSEF funding history, perception of the intrinsic rewards of review, professional age, and age. And the following characteristics had significant correlations with halo effects: innovativeness of research, mainstream/anti-mainstream of research, number of papers published in Korean journals by reviewers, and liking. (3) Interreviewer agreement was affected by an proposal characteristic of mainstream/anti-mainstream of research, and interreviewer reliability by innovativeness of research and variance of rating experiances of reviewers. (4) Funding decision had high correlation with dissatisfaction with review structure and process, perception of the effectiveness of feedback, and applicants' reaction to review. Dissatisfaction with review structure and process, and perception of the effectiveness of feedback mediated the relationship between funding decision and applicants' reaction to review. And, satisfaction with KOSEF funding history of applicants had moderating effects between funding decision and review satisfaction and between funding decision and review system satisfaction. (5) Blind review was found to be effective on the whole at keeping an author's identity secret from an experienced reviewer. Only 39.4% of the blind reviewers correctly recognized blinded applicants. There, however, were significant correlations between author recognition and the following characteristics of 1. the applicants: age and academic recognition, and 2. the reviewers: age and review experience. The implications of the findings for the peer review system, suggestions for improvement, and future research directions were discussed.
