A대학교에서 상대평가로 성적을 부여하는 강의의 강의평가 자료를 대상으로 강좌특성이 강좌별 강좌평가점수에 미치는 영향을 분석하였다. 분석 결과 강좌별 강좌평가점수는 강좌 수강생의 평균학년과 남학생비율이 높을수록, 수강인원이 적을수록 높게 나타났다. 이러한 결과를 바탕으로 평가자의 학년과 성별의 효과를 통제할 수 있는 평가모형을 제안하고 제안한 사례를 통하여 평가모형의 수행능력을 고찰하였다.

Purpose - This paper analyzes the student determinants of college non-completion and estimates the effects of each determinant on college non-completion. Design/methodology/approach - We use student panel data from a large Korean university from 2011 to 2021. Our results are from estimation of fixed-effects logit model. Findings - The results show that grade point average, participation in extracurricular activities, the number of counseling sessions with teachers, and financial aid are the main determinants of college non-completion. Academic probation, which is defined as any person who has a cumulative grade point average below a one point seven five, increases the non-completion rate by 2.6 percentage points and an one-point rise in extracurricular activities index reduces the rate by 0.1 percentage points. The effects of each determinant are heterogeneous across student sub-groups which are separated by gender, nationality, and academic discipline. Research implications or Originality - Tailored support programs for academically discouraged students that incorporate student characteristics and backgrounds are necessary to increase college completion rates and degree attainment.

Many students have misconceptions that upward direction force act on the object which is moving upward after being thrown vertically upward, and no force act on the object at the top of its flight because the object stop or don't' move at the top. To change these misconceptions, in this study, deductive reasoning tasks were used, and student's responses to the tasks were analyzed. In the first part of this study, student's prior conceptions about force and motion and student's deductive reasoning abilities were investigated. And the second part, student's explanations were classified to either the premise-based or idea-based explanation. In the case of the object which is moving upward, 62% of students who had misconception changed their misconceptions to physically correct concept, but, only 24% of students changed their misconceptions for the object at the top. For the first task, more students changed their misconceptions when they made responses based on premises than based on their own idea(p<.05), so, the first task can be helpful for conceptual change. 40% students changed their own misconception by reasoning deductively based on premises provided in the first task, but only 17% students changed by the second task. Student's reasoning abilities investigated in the first part of this study did not affect the conceptual change. Four students for the first task and one student for the second task did not change their misconception even though they made premise-based explanation and had high reasoning abilities.

본 연구는 벤처분야에 취업 또는 창업에 대해 고민하는 대학생들에게 진로상담 프로그램을 실시하여 변화를 측정함으로써 진로상담 프로그램이 대학생의 진로성숙, 진로자기효능감, 진로장벽에 미치는 영향을 분석하고자 실시하였다. A에 소재한 대학 재학생들 중에서 60명을 선정한 후 각각 30명씩 실험집단과 통제집단으로 구분하였다. 격주 1회 총 8회기의 진로상담 프로그램을 실시하였으며, 본 연구에서 나타난 주요 결과를 요약하여 제시하면 다음과 같다. 첫째, 벤처창업진로상담 프로그램에 참여한 대상자들은 참여하지 않은 이들보다 진로성숙이 향상되었다. 따라서 진로상담 프로그램이 대학생의 진로성숙 향상에 효과적임을 알 수 있었다. 둘째, 벤처창업진로상담 프로그램에 참여한 대상자들은 참여하지 않은 이들보다 진로자기효능감이 향상되었다. 따라서 진로상담 프로그램이 대학생의 진로자기효능감 향상에 효과적임을 알 수 있었다. 셋째, 벤처창업진로상담 프로그램에 참여한 대상자들은 참여하지 않은 이들보다 진로장벽이 감소되었다. 따라서 진로상담 프로그램이 대학생의 진로장벽 감소에 효과적임을 알 수 있었다.

Objectives : The bone proportional cun and body cun have been used widely for the location of acupoints in oriental medical clinic. The aim of this study is to compare the two location methods. Methods : 21 students were examined for the location of 6 acupoints (each 2 points in the 3 parts of upper limb, abdomen, and lower limb) using the twe methods. The data of location were analyzed with t-test. Results : In the upper limb, the data from bone proportional cun and body cun were proved to be different significantly. However, there was no significant difference between the data from the two methods in the abdomen and lower limb. Conclusion : The results of this study demonstrate that the oriental medical doctors should be more careful in the choice of appropriate method for the location of acupoints in the upper limb, while it is not important whether they use bone proportional cun and body cun in the abdomen and lower limb.

유비쿼터스와 대학의 만남은 U-Campus라는 새로운 서비스 분야로 많은 연구가 진행되고 있다. 본 논문에서는 U-Campus의 한 분야인 기자재 관리 및 학생 출석 관리 서비스를 RFID 시스템을 이용하여 새롭게 설계하고 구현하였다. 제안된 시스템은 기자재 관련 정보가 실시간으로 제공되며 검색을 통한 입고, 출고, 반품, 위치정보 등을 제공한다. 또한 학생 출석 관리에서는 학생들의 입실 및 퇴실, 강의정보를 제공한다. 본 논문에서 제안된 시스템을 사용함으로써 기자재 관리 및 학생 출석 관리에 소요되는 많은 시간과 인력, 비용을 절감 시킬 것으로 기대된다.

Purpose: The purpose of this study was to investigate the influence of ego-resilience and self-efficacy on satisfaction in major of nursing student. Method: Data were collected from 275 nursing students by means of self reported questionnaires about ego-resilience, self-efficacy and satisfaction in major from December 3 to 20, 2012. Results: There were positive correlations between ego-resilience, self-efficacy and satisfaction in major. The optimistic attitude in ego-resilience (${\beta}$=.56, p<.001), an associate's degree (${\beta}$=.38, p<.001), suitable to aptitude (${\beta}$=.17, p<.001), social self-efficacy (${\beta}$=.14, p=.039) and high employment rate (${\beta}$=.12, p=.033) were significant predictors of satisfaction in major. Conclusion: It is necessary to develop an effective intervention program to improve nursing student's ego-resilience, self-efficacy and satisfaction in major of nursing student.

The purpose of this study is to examine the concept and importance of the hidden curriculum, which has an influence on the learning, culture, and identity formation of medical students, and to examine the student culture related to the hidden curriculum. The hidden curriculum can be defined from various perspectives. However, these definitions commonly include the concept of the whole experience students gain from school life in implicit ways, even though the school does not intend it. The hidden curriculum is related to non-cognitive areas and the culture formation of students in various way, including positive and negative content, and is important since once this curriculum is formed, it has a long-term impact. Therefore, it is necessary to consider not only the formal curriculum but also the hidden curriculum in order to apprehend the overall educational outcome of medical school. For this purpose, schools need to not only support studies on the hidden curriculum but also to endeavor to provide faculty and staff with educational and administrative support so that they can understand the hidden curriculum and be equipped as a role model. Furthermore, medical students need to endeavor to form a positive student culture in order to establish an appropriate identity as a doctor in the future.

It is well known that the distributional properties of financial asset returns exhibit fatter-tails and skewer-mean than the assumption of normal distribution. The correct assumption of return distribution might improve the estimated performance of the Value-at-Risk(VaR) models in financial markets. In this paper, we estimate and compare the VaR performance using the RiskMetrics, GARCH and FIGARCH models based on the normal and skewed-Student-t distributions in two daily returns of the Korean Composite Stock Index(KOSPI) and Korean Won-US Dollar(KRW-USD) exchange rate. We also perform the expected shortfall to assess the size of expected loss in terms of the estimation of the empirical failure rate. From the results of empirical VaR analysis, it is found that the presence of long memory in the volatility of sample returns is not an important in estimating an accurate VaR performance. However, it is more important to consider a model with skewed-Student-t distribution innovation in determining better VaR. In short, the appropriate assumption of return distribution provides more accurate VaR models for the portfolio managers and investors.

본 연구에서는 원유시장의 변동성 분석에 적용될 수 있는 VaR(Value-at-Risk) 접근법을 고찰한다. 그리고 다양한 VaR 모형들(RiskMetrics, GARCH, IGARCH와 FIGARCH 모형)의 성과를 정규분포와 치우친 Student-t 분포 가정 하에서 평가한다. Brent 및 Dubai 시장의 일별가격 자료를 이용한 실증분석 결과에 따르면, FIGARCH 모형이 GARCH 모형이나 IGARCH 모형보다 원유시장의 변동성에 내재되어 있는 장기기억 특성을 잘 반영한다는 점에서 더 우월한 것으로 나타났다. 이러한 사실은 원유시장 수익률의 변동성에는 장기기억이 존재한다는 것을 의미한다. 그리고 VaR 분석 결과, 치우친 Student-t 분포 가정 하에서 추정되는 FIGARCH 모형이 롱 포지션과 숏 포지션 모두에서 정규분포 가정 하에서 추정되는 다른 변동성 모형들보다 원유시장에서의 투자 위험을 더 정확하게 예측하는 것으로 나타났다. 이러한 사실은 치우친 Student-t 분포 가정이 원유시장 수익률 분포에 내재되어 있는 비정상적 왜도와 첨도를 모형화하는데 더 적합하다는 것을 의미한다. 이와 같은 발견은 원유시장 구매자 및 판매자들이 원유가격의 움직임을 올바르게 측정하고 VaR을 정확하게 추정하는데 도움을 줄 것이다.
