공동구매는 ‘가격절감’, ‘위험감소’, ‘거래비용 절감’, ‘참여의식’등의 장점을 가지고 있다. 이러한 장점은 소비자들로 하여금 구매형태에 직ㆍ간접적인 영향을 미치는 것으로 나타났다. 반면 ‘시간지연’, ‘제품다양성 부족’, ‘결제수단’, ‘상품디스플레이’등의 단점을 가지고 있다. 이러한 단점들 역시 소비자들로 하여금 구매형태에 직ㆍ간접적인 영향을 미치는 것으로 나타났으나 반면 한번 거래를 하게 되면 계속해서 거래를 한다는 의견과 앞으로도 거래를 할 생각을 가지고 있으며 주변의 다른 이들에게도 추천하겠다는 생각을 가지고 있었다. 장ㆍ단점과 관련하여 공동구매를 ‘재수용 하는가’와 ‘주변사람들에게 권유할 것인가’를 연구하였다. 본 연구의 목적은 공동구매 특성이 공동구매를 수용함에 있어서 지속적인 수용을 할 것인가와 더불어 주변의 사람들에게 권장을 하는가를 파악하는데 있다. 본 연구에 대한 자료 수집방법은 D대학교의 재학생들을 대상으로 총 100부를 설문 조사하였으며, 수집된 설문지 중에서 불성실하게 응답한 설문지 8부를 제외한 총 92부를 유효한 설문으로 확보하였다. SPSS_WIN 10.0 패키지를 이용하였으며, 대상을 통하여 제품별(종류별) 선호도와 구매시(저가격, 안전성, 배송, 시간절감, 결제편리, 기타) 우선순위를 빈도분석 하였다. 또한 요인분석통한 타당도와 신뢰도 분석하고, 연구변수로 선정한 각 요소들을 이용하여 공동구매의 특성(가격대비 성능, 편리성, 결제안전, 다양한 제품 제공)에 따라 공동구매 재수용도와 주변사람 들에게 권유할 것인가에 영향력 정도를 파악하기 위해 회귀분석을 실시하였다. 조사결과 제품 선호도의 측면에서는 서적&음반, 의류&신발, 컴퓨터&주변기기 가장 선호하는 품목으로서 전자상거래와 거의 흡사하게 나타났으며, 구매시 가장 중요하게 느끼는 요소는 저렴한 가격과 안전&안정성으로 나타났다. 또한, 공동구매 특성에 대한 요인분석 결과로는 하나의 독립요인으로 존재하지만 결재안전, 다양한 제품제공의 요인들이 편리성 요인의 하부요인으로 존재하는 것으로 나타났다. 공동구매 특성이 재수용과 주변사람 권유에 대한 결과로는 재수용적인 측면에서는 ‘가격대비 성능’과 ‘다양한 제품 제공’이 유의한 영향을 미칠 것으로 나타났으며, 주변사람 권유적인 측면에서는 ‘가격대비 성능’이 유의한 영향을 미칠 것으로 나타났고 재수용성과 다르게 ‘다양한 제품 제공’측면에서는 영향을 미치지 않는 것으로 나타났다.

As foodservice industry has been developing, more people are interested in healthy life and want to learn cooking. This study validated the moderating effect of education program on cooking institutes. Also the present study revealed cause and effect relationship among the education environment, the satisfaction and reregistration intentions by conducting a survey for trainees in cooking institutes located in Busan and Gyeongnam area. For the purposes of the study, conjunction and organic cause-and-effect relationship of entire model was validated by using an exploratory factor analysis, confirmatory factor analysis and structural equation modeling with 313 trainees who have used cooking institutes. A nested model and basic model were established to analyze the moderating effect of education program. The adjustment role of education program was validated with ${\chi}^2$ difference considering the degree of freedom between two models. As results of the analysis, the education service was statistically significant in all factors except the effect on education satisfaction. The education program has moderating effect on the relationship between the level of instructor and satisfaction degree, and between satisfaction degree and the reregistration intentions. Therefore, this study suggests that managers of cooking institutes should recruit instructors with excellent capability in order to operate the education program very well.

Purpose: In order to provide basic information for the development of nursing programs, health promoting behavior of students rewriting college entrance examinations was examined and factors related to health promotion were identified. Method: Data were collected by questionnaire from 804 examines in Seoul and Gyeonggi Province and were analyzed using the SAS program with t-test, ANOVA, Scheffe's test and Pearson correlation coefficients. Result: The mean score for health promoting behavior was 2.50. The highest score for the sub-areas was harmonious relationships and the lowest was, professional health maintenance. There were significant differences in health promoting behavior according to the following general characteristics; religion, frequency of rewriting college entrance examination, economic burden, parents' education level, grade, satisfaction with parents, friends and rewriting of college entrance examinations, parents' health concernsand knowledge of health, need for health education, and health condition and chronic disease over the past year. Correlations between health promoting behavior and family support and self-esteem were positive. The variables that influenced health promoting behavior were family support ($24.5\%$), self-esteem ($11.3\%$), anxiety ($2.6\%$), and stress of studying ($0.5\%$), explaining $38.9\%$ of the total variance. Conclusion: These results will help to develop a nursing program that enhances health promoting behavior of students rewriting college entrance examinations.

The Ministry of Education of Korea announced the university structural reform plans which reduces 160,000 of the university entrance quota during 10 years from January 2014. Because the reduction plans of entrance quota influence regional economy as well as students and universities, naive evidence of the Ministry of Education of Korea is disappointed. In this research, we forecast the total number of the university entrance exam candidate by 2032 including not only third grade high school students but also repeaters according to the 16 metropolises and provinces in Korea. We also forecast the regional university recruiting rate using the forecasts of the total number of the university entrance exam candidates. However, we can not make more realistic results because we can not apply the inter-regional movement of students to the forecast. In order to handle this limitation, we first estimated the rank of the whole 7,277 departments of all universities in Korea and assigned the quotas according to the estimated rank for each departments and then we calculated the local university recruiting rate. The estimated the university recruiting rates of 16 metropolises and provinces can provide more noticeable results of characteristics and problems than that of nationwide.

In line with the recent job insecurity, the preference for teaching jobs has been increasing for private and educational colleges. However, the T.O., announced by the Ministry of Education in tandem with the decreasing number of people, is decreasing every year, while the competition rate is rising steeply due to the increase in the number of students. As a result, the university is becoming a huge hagwon for teacher-nominee competitive tests as it tries to concentrate on the recruitment exam at the same time as entering the university. In this study, we will present a blueprint for school life to students enrolled in private universities by identifying the connection between the overall use of school life and study groups by students using deep learning.

Effects of the biosurfactant produced by Rhodococcus erythropolis on the solubilization and biodegradation of phenanthrene were investigated. Based on surface tension measurements, the average critical micelle concentration of the biosurfactant was estimated to be about 16mg TOC/L. The apparent solubility of phenanthrene increased linearly with the addition of biosurfactants above the CMC, and the concentration of solubilized phenanthrene was 38.9mg/L in 322mg TOC/L biosurfactant solution. The weight-solubilization ratio of biosurfactants for phenanthrene was approximately 118.8mg/g, this value was over 5 times greater than that of sodium dodecyl sulfate. Using a known phenanthrene degrader, batch phenanthrene biodegradation experiments were conducted with and without biosurfactants in liquid culture. The rate and extent of phenanthrene mineralization by the phenanthrene degrader with biosurfactants were much greater than those without biosurfactants. The greater phenanthrene mineralization observed in the presence of biosurfactants is attributed to the increased phenanthrene concentration in the aqueous culture due to the partitioning of the compound to biosurfactant micelles. The biosurfactant did not exhibit any toxic effect on mineralization of glucose by the phenanthrene-degrader.
