The interaction between users and games is an important factor in game development. In this paper, we consider Leaderboard UI in shooting game and study user's performance level according to presence or frequency of providing Leaderboard UI. For this research, we developed a third person shooting game and conducted experiments for 80 college students. The results of the experiments were analyzed using statistical significance using the T-test method. Finally, in order to improve user's performance level, we conclude that the user's gaming experience is a bigger factor than the presence or frequency of providing Leaderboard, causing a significant difference.

This study analyzed the effect of participation in work and learning ducal system of small businesses on employees' job competency enhancement. The study results showed that performance assessment significantly affected job competency enhancement(p<.001, ${\beta}=.514$). In conclusion, it is suggested that small businesses should consider performance assessment more important and actively include it in training program as generally utilizing off-the-job or on-the-job training method. This study provided implications for analyzing the effect of participation in work and learning ducal system of small businesses on employees' job competency enhancement, so it broadened the scope of the study about performance of work and learning ducal system and verified the effectiveness depend on the type of training.

This study was carried out to suggest producers' marketing direction for GAP certified rawginseng using STP(segmentation, targeting and positioning). In order to fulfill this object, conjoint analysis and cluster analysis were used. The main results are as follows. Based on the results of part worth for attributes such as safety, size, and price, GAP certified raw-ginseng, large size, and low price were preferred to conventional ginseng, small size, and high price respectively. In the relative importance for each attributes, safety was 47.2%, size was 30.0%, and price was 17.8%. As a result of market segmentation, 3 consumer groups(large size preferred, safety preferred, lower price preferred) were classified. Among those groups, the safety preferred group was selected as a target market for GAP certified raw-ginseng and its market size was estimated approximately 2,968 tons which is 26.8% of total raw ginseng market.

금강살리기 사업은 장래 치수 및 물 부족 현상과 가뭄에 대비하여 용수 확보를 위해 금강 본류에 금남보, 금강보, 부여보 3개의 보를 건설하고 있다. 이러한 보의 건설은 하천의 흐름을 차단하여 토사퇴적에 많은 영향을 미치며 하상의 형상을 변화시킨다. 한 지점에서 하상재료 및 하상단면이 변화되면 하천 전 구간에 걸쳐 장기간의 하상변화를 일으키게 되며 이를 예측하고 분석하는 작업은 하천계획 및 관리를 효율적으로 수행하기 위해 매우 중요하다. 현재 금강에는 금강보가 건설중에 있으며 공사 후 보에 의해 상류로부터 하류로의 유사 유입이 차단되고 보 방류량이 인위적으로 조절되기 때문에 보 하류의 하상변동을 장기적이고 거시적인 관점에서 모니터링 하는 것이 필요하다. 본 연구에서는 금강보 건설 기간 중 하상변동 및 퇴적 토사의 입도 변화양상을 조사하기 위해 보 상 하류에 모니터링 지점을 선정하였고, 하상단면 수심측정기를 이용하여 하상변동 모니터링과 5회에 걸쳐 현장의 토사시료를 채취하여 하상재료 입도분포를 분석하였다. 그 결과 금강보 상류 모니터링 지점은 하상침식에 의해 하상고의 평균높이가 0.29m 낮아졌고, 하류 모니터링 지점 역시 하상고의 평균 높이가 0.05m 낮아졌으며, 하상형상의 모습은 큰 차이를 보이지 않았다. 또한, 5회에 걸쳐 하상재료를 채취하여 균등계수 및 곡률계수를 통해 입도분포를 분석한 결과 체가름시험 규정에 의해 5회 모두 '나쁜입도'로 분류 되었다.

본 연구는 한우의 도체 품질을 결정하는 육질 등급 판정 항목이자 경제적으로 매우 중요한 근내지방도, 배최장근 단면적 및 등지방두께에 대한 개체별 유전능력 차이를 조기에 식별하는 선발 기술을 개발하기 위해 세포내 지방산 농도 및 다양한 세포 및 지질대사를 조절하는 지 방산결합 단백질(H-FABP) 유전자의 전체 염기서열을 분석하여 SNP를 검출하고, SNP marker가 한우의 도체 및 육질 형질에 미치는 영향에 대하여 분석하고자 수행하였다. 염기 서열 분석 결과 총 6개의 SNP를 검출하였고, 이들 중 4개의 주요 SNP를 선발하여 PCR-RFLP기법으로 genotyping하고, 각 SNP marker가 한우 도체 및 육질 형질에 미치는 영향을 통계분석 하였다. H-FABP의 C3523T SNP marker가 한우의 배최장근 단면적 및 등지방 두께에 유의적인 영향을 미쳤다(p<0.05). 따라서, 본 연구를 통해 개발된 한우 H-FABP 유전자의 특정 SNP marker는 배최장근 단면적은 넓고 등지방두께는 얇은 우수한 고급육을 생산하는 한우의 조기 식별 및 육질진단에 매우 유용한 SNP분자 표지로 활용할 수 있을 것으로 기대된다.

This study is a descriptive survey research conducted to examine the influence of learning efficacy on nursing students' self-confidence. Research subjects included a total of 231 university students in D city, and the data were analyzed by t-test, ANOVA, Pearson's correlation coefficients, and multiple regression. The study results were as follows: Learning experience was high in the order of vital sign check, intramuscular injection, and subcutaneous injection. Recognition of importance was also high in the order of vein therapy, intramuscular injection, and vital sign check. Self-confidence was high in the order of vital sign check and wearing of protective equipment. As for the learning experience, there were significant differences depending on the students' school year. As for the correlation among all variants, 'learning experience of nursing skills', 'self-confidence', 'learning self-efficacy', and 'self-efficacy' had a positive correlation with each other. Based on these study results, it is necessary to develop an educational strategy that ensures students' education of self-efficacy and improvement of their learning experience to enhance their self-confidence.

The purpose of this paper is to propose the policy change of teachers education in Korea with an analysis of America statistical literacy education. we found the difference of statistical literacy education between Korea and America with each nation's social and educational environment. We can get the need of new change for statistic teacher's education in Korea. We think of Mathematics teachers should know about the difference between statistics and mathematics at school mathematics. And they should know the new change thinking about teaching method and process assesment methods. Second, Teachers should focused on teaching of problem solving and statistical thinking ability based on data analysis than the teaching of probability and mathematical theory.

The purpose of this study was to investigate the effect of major satisfaction, academic engagement of confidence in performing core nursing skills in nursing students. The subjects were nursing students residing in J provincial and 112 questionnaires were analyzed. There were significant differences in confidence in performing core nursing skills with age(F=5.52, p<.001), Images about the nurse profession(F=10.2, p<.001). There was positive correlation between confidence in performing core nursing skills and major satisfaction (r=.563, <.001). The factors affecting confidence in performing core nursing skills of the major satisfaction(𝛽=.338 P<.001), academic engagement(𝛽=.195, p<.027), explaining 35% of the variance. Therefore, based on the results of this study, it will be an important basic data for the development of education to improve the core nursing skills of nursing university students.

The purposes of this study was to analyze the relative efficiency of nineteen Jeju Self-Governing Schools (JSGS) in elementary level by using DEA (Data Envelopment Analysis). Major results from the study are as follows: First, there were significant differences on the relative efficiency among JSGS, which might come from operation factors rather than from size factors of JSGS. Second, to improve the relative inefficiency of JSGS, it is quite suggestive that satisfaction of both students and parents would be developed, and that the quality of educational programs should be developed by analyzing especially parents characteristics and reflecting their needs. Lastly, the perspective of efficiency, which is a measure of the optimal usage of available school resources, should be adopted and used for school assessment in order to develop the relative efficiency of JSGS.

The purpose of this study was to analyze the relationship between sanitary knowledge score and sanitary management performance among school foodservice employees. For this purpose, a paper-based questionnaire was developed and distributed to 300 school foodservice employees in Jinhae-gu, Changwon from May 13 to June 10 in 2009. A total of 276 responses were received and analyzed. The results of this study were as follows. The sanitary knowledge score of school foodservice employees was 16.60 (total score: 20). Their sanitary management performance level was 4.77 (based on a 5-point Likert scale). We found that sanitary management performance level of high sanitary knowledge score group was significantly higher than that of low sanitary knowledge score group (P<0.001). There was a significant positive correlation between sanitary knowledge score and sanitary management performance of school foodservice employees (P<0.01). Regression analysis showed that sanitary knowledge score of school foodservice employees had a positive effect on sanitary management performance (P<0.001). It implies that as school foodservice employees' sanitary knowledge increased, their sanitary management performance increased. In conclusion, to improve the sanitary quality of school foodservice, school foodservice employees' sanitary management performance level should be increased by improving their sanitary knowledge. So, a systematic and consistent sanitary education program should be conducted for school foodservice employees.
