This paper examines the effect of the government college loan program in Korea on student academic performance, dropout decisions and loan defaults. While fairness in educational opportunities has been guaranteed to some degree through this program, which started in 2009, there has been a great deal of controversy over its effectiveness. Empirical findings suggest that recipients of general student loan (GSL) lower academic performance than those who received income contingent loan (ICL). Moreover, for students attending private universities, a higher number of loans received increased the probability of a dropout decision, and students from middle-income households had a higher probability of being overdue than students from low-income households. These findings indicate that expanding the ICL program within the allowance of the government budget is necessary. Furthermore, providing opportunities for students to find various jobs and introducing a rating system for defaulters are two necessary tasks.

The purpose of this study was to investigate the student nurse's perception and performance about the protecting behavior of the medical information. The subjects of the study were 365 senior nursing students. The data was analyzed by SPSS PC 19.0 program. 1) The mean scores of perception and performance by student nurse's on protecting behavior of the medical information were $4.39{\pm}0.40$ and $3.71{\pm}0.57$. 2) The perception on protecting behavior of the medical information was heavily dependent on the following age. 3) The performance on protecting behavior of the medical information was heavily dependent on the following career interests and work unit. 4) There was a positive correlation between the perception and performance about the protecting behavior of the medical information. The results showed the statistically significant partial correlation between the perception and performance. Therefore, it is suggested to apply the concrete education program to enhance the perception in order to improve the performance.

본 연구는 동료(peer)에 대비한 학생의 상대적인 학업성취가 진로 결정에 어떠한 영향을 주는지를 살펴본다. 구체적으로 학교 내에서 학생들의 상대적인 수학 순위가 이과 선택에 미치는 영향을 분석하였다. 분석을 위해 서울시 소재 학생들의 패널데이터를 이용하였으며, 수학 성적을 통제하더라도 상대 순위가 낮은 경우 이과에 진학할 확률이 11%포인트 이상 감소함을 확인하였다. 높은 상대 순위는 여학생에게 추가적인 양의 이과 진학 효과를 나타내 상대 순위가 성별로 다르게 작용함을 보였다. 분석 결과에 따르면 상대 순위효과 중 약 12%만이 자신감과 같은 주관적 평가에 의해 설명되며, 이로 미루어보아 내신 성적을 통한 경로가 더 지배적일 것으로 추측할 수 있다.

The paper-and-pencil multiplce choise test has been widely used to identify gifted and talented student in Korea. Such test have several drawbacks; such~a s not being able to assess creative problem solving abilities and high level thinking abilities which are important characteristics of gifted students. The Korean Educational Development Institute (KEDI) developed a performance assessment which challenged traditional methods of identification. The 5-day summer camp was held to select gifted students for the Korean Minjok Leadership Academy. 211 students were evaluated in the aspects of creative problem solving abilities, high level thinking abilities, task commitments, and cooperativeness with various performance tasks, such as essay tests, conversations, oral examinations, computer simulations, puzzles, experiments, group discussions, debates, research reports, and games. As a result, it was found that there were several limitations of the performance assessment in terms of low reliability, requiring high costs and many professionals, and taking long times and large spaces. Expanding and continuing research should follow in order for a performance assessment to use widely as an identification methods because it assesses 'true' abilities of each individual student. follow in order for a performance assessment to use widely as an identification methods because it assesses 'true' abilities of each individual student.

Data mining technique was used to track student's performance during years studding in college and determine the impact of GPA_SEC on the GPA student rates according to the current academic advising method used on student's status. The study utilized a sample of 5436 individuals were drawn from two colleges in Majmaah University, KSA during 2013-2018 period. The results showed that the student's completion status in terms of graduation, dropout, Stumbling or dismissed was classified according to the average grades of admission from secondary school GPA_SEC. The results show the effect of the current academic advising that most of students gain less grades comparing with GPA_SEC in addition that the higher GPA_SEC was the higher graduation, dropout and dismissed decreased when GPA_SEC was high.. Therefore, the study recommends tracking students academically to evaluate their results of each semester to find out the causes of the deficiencies and addressing them within the departments.

원거리 발성은 화자 인증 시스템의 성능을 하락시키는 주요 요인으로 알려져 있다. 본 논문에서는 교사 학생 학습을 이용하여 원거리 발성에 의한 화자 인증 시스템의 성능 하락을 보상하는 기법을 제안한다. 교사 학생 학습은 미리 학습된 교사 심층신경망의 출력과 학생 신경망의 출력이 같아지도록 학생 신경망을 학습하는 기법이다. 여기서 교사 신경망에는 근거리 발성을, 학생 신경망에는 원거리 발성을 입력한 뒤, 두 신경망의 출력을 동일하게 만드는 과정을 통해 원거리 발성을 보상할 수 있을 것이라고 기대하였다. 하지만 원거리 발성을 보상하는 과정에서, 근거리 발성에 대한 인식률이 저하되는 현상을 실험적으로 발견하였다. 위와 같은 현상을 예방하기 위해 본 논문에서는 교사 심층신경망을 학생 심층신경망의 초깃값으로 사용하는 기법과 학생 심층신경망을 근거리 발성에 대해서도 학습하는 기법을 제안하였다. 모든 실험은 원 음성을 입력 받는 심층신경망을 활용해 수행하였다. 동일한 발성을 각각 4 채널로 근거리와 원거리에서 자체적으로 수집한 문장 종속 데이터셋을 활용하였다. 동일 오류율을 기준으로 근거리 / 원거리 발성에 대한 화자 인증 성능을 평가한 결과 교사 학생 학습을 사용하지 않을 경우 2.55 % / 2.8 %, 기존의 교사 학생 학습을 사용할 경우 9.75 % / 1.8 %, 제안한 기법들을 적용한 경우 2.5 % / 2.7 %의 오류율을 확인하였다.

Distance teaming systems have become popular tools for teaching and learning. The purpose of this study is to analyze influence of instructor factors and media richness on student's intention th use and performance in distance teaming. We used TAM as a theoretical foundation to explain student's behavior. The model was tested using LISREL analysis on the sample of 246 users rho have experience with the distance teaming systems. The results show that instructor factors such as luぉ style and attitude have partial effects on perceived usefulness, ease of use and media richness. In addition, results also show that both TAM variables and media richness strongly predict intention In use of the distance loaming system Finally, the usage intention has a positive effect on teaming performance. Implications of these findings are discussed for researchers and practitioners.

In recent years, there has been an argument that the academic performance of college students taught in English might be lower than those exposed in Korean under ceteris paribus environment. This paper examined the validity of this argument against the effectiveness of teaching-in-English, using student data from investment courses at a leading national university in Busan. Of a total of 165 students, 77 students took the teaching-in-Korean class (cohort A), whereas 88 students registered for the teaching-in-English class (cohort B). The findings did not support the popular argument. There was no significant difference in academic performance between student cohort A and student cohort B.

Purpose: The purpose of this study was to identify changes in nurses' image of student nurses before and after their first clinical practice. Method: Study samples were composed of 78 student nurses who were from nursing dept. of one college in G city. All participants had their first clinical practice for 4 weeks at two general hospitals in Gwangju. The internal consistency of the total scale was Cronbach's $\alpha$= .883. Results: After the first clinical practice, the mean score of nurses' image in general was lower than that of nurses' image before the clinical practice. In five subcategories, before the first clinical practice, professionalism and expertness were the highest followed by role performance, vision of a career, and temperature as a nurse in order but after the first clinical practice, professionalism was the highest score followed by expertness, temperature as a nurse, role performance, vision of a career in the mean scores of nurses' image. Conclusion: Based upon these findings, clinical practice will play an important role in improving role performance and vision of a nursing career for student nurses, so nursing administrators should make efforts to improve image of nurses in a variety of practice.

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.
