The Brain Korea 21 (i.e., BK21) is a state-led higher education funding project that started in 2013. Previous literature investigating the effectiveness of the project mainly focused on massive quantitative outcomes of funded teams, and many studies reporting only self-reported data of graduate students who participated in the project. Therefore, there were not many BK21 studies that thoroughly examined the graduate students' performance, ability, satisfaction, etc. This study aims to determine the effect of the BK21 project participation on graduate students' academic performance, using objective (the number of published papers), self-rating (graduates' satisfaction), and other-rating (advisor's performance evaluation) data, which were sampled from 2013 to 2019 from a single funded team on a one-departmental-unit. The results showed that the participating graduate students had more published papers, and had higher performance evaluation scores in research, and overall abilities, than the non-participating graduate students. Further, participating students were largely satisfied with BK21 supports. This study has significance in that it demonstrates the positive influence of the BK21 project on graduate students' academic performance and satisfaction by the thorough investigation of a single social science funded team.

As the market sheare of the Chinese game market across the world has been largely expanded over a decade, big game exporters of USA, Japan, Korea have developed Chinese factors and promoted export strategies, that target China. The Purpose of this study is to analyze the popular game characters of USA, Japan and Korea in order to provide empirical analysis of traditional Chinese elements applied in existing games. The RPG games in USA, Japan and Korea were selected for the contents analysis of the Chinese elements to show how the existing game companies used Chinese elements. The main findings of the research from survey data are rather inconsistent with the content analysis. In particular, all the RPG game companies of USA, Japan and Korea showed a remarkable ratio of using Manzu clothes more than Hanzu clothes. But, the preference of real game users on the Manzu style were lower than Hanzu style. Moreover, Chinese users showed more preference of the game character background that users more deepen Chinese culture. We suggest that applying Chinese elements need to be more selective based on real user's demand.

We can and must improve the diagnostic images using available knowledge and technology. At the same time we must strive to reduce the patient's integral and entrance radiation dose. Reducing the integral dose to the patient during the radiologic procedure is a primary concern of the patient, especially the pediatric patient, the radiologist and the technologist. A 100cm focal film distance generally is used for most over-table radiography. The early x-ray tubes and screen film combinations required long exposures, which often resulted in motion artifacts. But nowaday, we have the generators and x-ray tubes that can deliver the energy necessary in a very short time and the receptors that can record the information just as rapidly. And, we performed this studies to evaluate the patient exposure dose and the image quality by increasing focal film distance in diagnostic radiography. There are many factors which affected to exposure factor, but we studied to verify of FFD increase, only. Effect of increasing the focal film distance to a 140 cm distance was tested as follows; 1. The focal film distances were set at 100, 120, and 140cm. 2. A 18cm acryl(tissue equivalent) phantom was placed on the table top. 3. An Capintec 192 electrometer with PM 05 ion chamber was placed at the entrance surface of the phantom, and exposure were made at each focal film distances. 4. The procedure was repeated in the same manner as above except the ion chamber was placed beneath the phantom at the film plane. 5. Exit exposure were normalize to 8mR for each portions of the experiment. Based on the success of the empirical measurements, a detailed mathematical analysis of the dose reduction was performed using the percent depth dose data. The results of this study can be summerized as followings ; 1) Increasing FFD from 100 cm to 140 cm, we would create a situation that would have a significant effect on the overall quality of radiograph and achive the 17.42% reduction of entrance dose and the 18.95% reduction of integral dose that the patient receives. 2) Thickness of Al step wedge for equal film density increased with the long distance. 3) Increasing FFD, Magnification of image was lowered. 4) Resolution of image also increased with the FFD. As the results described above, we strongly recommend using the long FFD to provide better information for our patients and profession in abdomen radiographic studies.

Now it is a proper time to discuss on the issue of crisis negotiation more in-depth. Thus far, studies on crisis negotiations have been mere manual style guidelines of "what to do". More substantial and rigorous theoretical propositions and empirical studies await for the future development of crisis negotiation field. This article contributes to the theoretical enrichment of the study of crisis negotiation field. Conventionally, two problems of misperceptions are raised in crisis negotiation. For instance, even though two parties used the same word, there can appear a substantial difference. Even worse, in many cases parties of negotiation send misinformation intentionally or unintentionally. This noise of communication can cause a serious misperception for parties of crisis negotiation including police officers, perpetrators, and hostages. However, this issue has not yet discussed in the field of crisis negotiation in Korea. This paper pointed out such important but not yet focused issue. It first discusses about the problem of perception and misperception. Next, it presents the negative impacts of such perception and misperception in crisis negotiation communication. Finally, it suggests the policy implications.

There has been discussions and investigation on the nexus between religion and citizen's supports for suicide attacks and terrorist groups conducting such acts. In terms of the relationship, there were two potent hypotheses attempting to explain the process and mechanism of the relationship: religious belief hypothesis and coalitional commitment hypothesis. previous studies examined these hypotheses have been carried out across different cultural, religious, and political contexts. Until today, however, there are still lack of concrete evidence, which is generated from empirical studies, supportive evidence for any of these hypotheses. Therefor this study aims to investigate the association between religion and popular support for suicide attacks by using a survey data collected from three middle east countries, Egypt, Morocco, and Pakistan. In analysis, a step-wised regression analysis conducted with a set of variety of variables considered to be related with the association. This study found that variables reflecting religious belief hypothesis, such as prayer to God, religious devotion were unrelated to support for suicide attacks. Yet, prayer time predicted reduced supports for suicide attacks. Further, attendance at religious services, thought to enhance coalitional commitment, predicted support for suicide attacks. Yet, it showed negative association with support for suicide attacks. These findings suggest that regular attendance at religious services and regular prayer have combined effects reducing on the willing to support for suicide martyrdom. However, this study findings affirmatively support for neigher religious belief hypothesis nor coalitional commitment hypothesis. Instead, it suggests the needs for further research examination on the relationship as well as corrections of these hypotheses. Finally, Implications for the research findings for preventing suicide attacks are discussed.

The sport industry has been continuing to grow in the past few decades in the U.S., and it presents significant opportunities for the practitioners to increase the number of patrons. To convert this opportunity to optimum benefits for a sport organization, one of the most significant challenges for the practitioners would be promoting sport attendance and repatronage. So far, many studies have tried to identify variables that affect the level of sports attendance. However, many of these variables are rather uncontrollable due to the nature of the sports and contingencies that are derived from many areas of uncertainties. Thus, to acquire competitive advantage and profit maximization, it would be essential for the managers to focus on understanding controllable elements. This study found that many controllable variables that influence sports attendance coincide with the servicescape elements which have been widely used in the hospitality industry since 1992. In the light of the conceptual framework of servicescape, this study also attempted to isolate the controllable variables that can be utilized to increase the sports attendance. This study presents its significance not only in extending the application of servicescape concept to the sport industry, but also in providing suggestions for future empirical studies that would further identify these variables, gauge the relationship between those variables, and assess its impact on the sports attendance.

In this study, we introduce various hyperspectral data processing techniques for the monitoring of shallow and coastal waters to enlarge the application range and to improve the accuracy of the end results in Korea. Unlike land, more accurate atmospheric correction is needed in coastal region showing relatively low reflectance in visible wavelengths. Sun-glint which occurs due to a geometry of sun-sea surface-sensor is another issue for the data processing in the ocean application of hyperspectal imagery. After the preprocessing of the hyperspectral data, a semi-analytical algorithm based on a radiative transfer model and a spectral library can be used for bathymetry mapping in coastal area, type classification and status monitoring of benthos or substrate classification. In general, semi-analytical algorithms using spectral information obtained from hyperspectral imagey shows higher accuracy than an empirical method using multispectral data. The water depth and quality are constraint factors in the ocean application of optical data. Although a radiative transfer model suggests the theoretical limit of about 25m in depth for bathymetry and bottom classification, hyperspectral data have been used practically at depths of up to 10 m in shallow and coastal waters. It means we have to focus on the maximum depth of water and water quality conditions that affect the coastal applicability of hyperspectral data, and to define the spectral library of coastal waters to classify the types of benthos and substrates.

This study aims to identify the micro-level, social psychological foundation of regionalism and analyze its change and continuity by comparing 1988, 2003, and 2016 survey results. Drawing on the theory of prejudice and social identity, it clarifies the concept of regionalism and examines its affective, behavioral, cognitive implications. In the empirical analysis, where it takes advantage of relevant questions of the same or similar wording in three nationally representative surveys, the study identifies the changes in regionalism at the individual level focusing on anti-Honam prejudice and discrimination and attribution of regional conflict. First, anti-Honam prejudice has been in decline nationally as well as regardless of where one has grown up, except for Daegu/Kyungpook area. Second, anti-Honam prejudice has been weakened among younger generations while regional party identification now affects the sentiment in the direction of regional cleavage overlapped with ideological leanings. Third, while most respondents do not experience explicit discrimination, Honam natives are still more likely to experience discrimination, especially identity and self-esteem related, due to his or her home town. Fourth, Honam natives have been more likely to attribute regional conflict to an external, structural factor like government economic policy and less likely to a subjective one like regional sentiment, which seems to be consistent with attributional attitudes of the victims of prejudice. The study ends with the discussion of how to reduce further anti-Honam prejudice, which includes contact hypothesis, recategorization, cross-categorization, and de-categorization.

The purposes of the study are to describe the feature of the program components, and to identify their changes in the process of designing the social work programs in the community service agencies in Korea. In order to achieve these purposes, the researchers constructed an analytical framework including 24 program components derived from the related literatures. Data was collected by questionnaires answered by the social workers who were in charge of the program development and implementation. Descriptive statistics analysis and factor analysis were applied to exam the features of the program components in 195 social service programs developed by the funds from the Community Chest of Korea and a private funding foundation. As the result of the analysis, the three noticeable features are found; (1) the agencies have very actively involved in the designing work in the process of developing practice guideline, however they have less involved in the designing work in the process of implementing program; (2) program components which are low level in design activities are intervention models, staff education, and practical ethics; (3) 8 categories of components derived from the theoretical perspective are reduced to 6 categories in the process for developing practice guidelines, finally to 4 categories in the process for implementing the programs. The implications of major findings were discussed in academic and practical perspectives in Korea, including future research works in the area.

The main purpose of this paper is to analyze the quality of life of poor women. This study utilized data combined KLIPS with Time Use Survey for an analysis and analyzed time at the intersection of the class and gender. With discretionary time as center, this study investigated poverty status from the quality of life. And in order to make comparison more clearly, object was classified into 4 groups; non-poor male, poor male, non-poor female and poor female. Study results are as follows; First of all, poor women had the shortest discretionary time among all the groups and also had highest poverty rate of living quality. And this study found that deprivation of non-poor female headed householder is serious. Second, analysis of inequality level between and within groups through Theil index indicated that gender influence in poor strata was 3 times higher than that of non-poor strata. This study found that poor women experienced mixed exclusion at the point where gender and class crossed. And this study also has a meaning that an empirical analysis was conducted through above matters on secondary poverty and hidden poverty of poor women which existing researches were unable to discover.
