Faculty advisors play a vital role in a learning and adjustment process of doctoral students at their work, department, university and discipline by sharing and exchanging relevant information and knowledge in the profession. Despite the important role of information practice in doctoral advising, few studies have investigated the informational aspects of faculty advisors and their students. Thus, this study aims to consider the distribution of information exchanged between faculty advisors and their doctoral students and relate them to doctoral students' demographic characteristics (gender, age, race and/or ethnicity, degree, and stage of doctoral work). The findings of this study show that overall information exchange is most frequent at the work level followed by the discipline, school/department, and university levels. In particular, information exchange at the work and discipline levels explains the characteristics of doctoral education, socializing students into both student and professional roles. In addition, there are statistically significant differences in information exchange along certain dimensions according to the advisee's gender, age, race and/or ethnicity, degree, and stage of doctoral study, suggesting that information needs and seeking behavior may vary according to the demographic characteristics of advisees.

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.

Student Team Achievement Division (STAD) is a co-operative learning approach premised on a group learning activity that emphazises learning as a social exchange of knowledge between students, in which each student is accountable for his or her own learning and is also encouraged to assist others in achieving their goals. It promotes the cognitive, psychomotor, and emotional growth of students involved in the team. By random sequencing, 60 participants were allocated to interventional group (n=30) and control group (n=30). The participants of the interventional group were subjected to STAD strategy and participants of the control group were instructed to do a conventional self learning on the ventricles of brain. The outcomes were statistically analysed. It was found that the performance of the students is far better with STAD approach than conventional self learning. Our study has shown that Students team Achievement Division can be used as an effective tool for Peer assisted Co-operative Learning in Anatomy. Further studies can be done to investigate the contribution of STAD to teaching other disciplines of Anatomy and other basic medical sciences.

이러닝의 발전과 더불어 다양한 학습도구의 개발 그리고 이러닝 콘텐츠의 공동활용 등 이러닝을 통한 교류가 활발하게 이루어 지고 있다. 그러나 각각 LMS의 상호 연동을 고려하지 않고 개발되었기 때문에 이러닝 교류시 문제점이 나타나게 되었다. 특히 대학간 이러닝 교류는 학습자 정보교환 중심의 교류, 강의(교수자) 정보교환 중심의 교류 등 여러 가지가 있으나, 이들 모두 직접적인 연계가 이루어지지 않기 때문에 여러 가지로 문제점이 많이 나타났다. 이에 본 논문에서는 이러닝 교류의 사례를 분석하고, 문제점을 도출하여 효율적인 LMS 상호 연동에 대한 모형을 설계하여 제시하였다. 우선 먼저 학습에 가장 필요로 하는 학습요소 즉, 강좌개설정보, 강의정보, 사용자정보, 수강정보, 학습이력정보를 연동 데이터로 정의하였으며, 뷰를 이용한 데이터 연동 테이블을 통해 LMS를 연동하였다. 실험결과 학습자와 교수자의 접근성이 편리하게 나타났으며, 데이터 교환이 없기 때문에 업무 프로세스가 현저히 줄었다. 향후에는 다양한 학습요소에 대한 연동과 세션처리, 보안을 고려한 LMS 연동이 연구과제로 남아있다.

Students' concepts of scientific phenomena have become a point of focus in science education research. This study investigated into developmental process and mechanism of the students' respiration concept through a cross-age study. This study utilized the 1st, 3rd, 6th grade elementary students to find out changes in student's understanding of the concept of respiration. The 1st and 3rd grade level students were interviewed what the respiration mean and whether each of living things respires, etc. The 6th grade students were interviewed and tested. Respiration is a word that students come across often in everyday life. It was found that they were more likely to associate respiration with its more common concept of breathing or gas exchange as opposed to its more scientific definition as the process in which nutrients are oxidized to provide energy. This trend didn't improve as they advanced grade. This is an indication that the knowledge system of student is split into a generic knowledge system and scientific knowledge system. Understanding of concept increased and differentiated across grade levels but that understanding was limited. They overcome their tendency to base their understanding of respiration on their understanding of human phenomena and learn to integrate their understanding of biological phenomena through a one organ - one role type of logic. They also intuitively explain everything based on their own experience.

Purpose: The paper employs the theory of planned behaviour, social identity theory, social presence theory, and social exchange theory to propose a model for using the social media platform Facebook in distributing information in universities. Research design, data and methodology: Data were obtained from 618 students at Hanoi University of Industry (HaUI) in Vietnam. The study used structural equation modeling in SPSS and the statistical analysis software AMOS version 24 to explore the information distribution role of Facebook. Results: Findings reveal that subjective norms and social presence play a key role in driving students to use Facebook for studying. In addition, university administrators can boost student satisfaction and academic achievement through Facebook. Interestingly, students who strongly identify with the brand name of the university have a strong connection with the university are more likely to engage in behaviors supportive toward the university. Conclusions: These findings show that Facebook had played a key information distribution role in universities. Thus, the study provides the executive board of the university and teachers can gain new understanding of why students employ Facebook for studying as well as capitalize on the platform to improve several operational metrics such as brand identification, student satisfaction, and academic achievement.

The purpose of this study is to investigate a student's career maturity during a career exploration program based on the ecological system perspective and to propose directions for the career maturation process to help H. Meister High School students to get jobs. A single-case 12-session career exploration program was applied to a first-year student at H. Meister High School in U. City for 90 minutes per session twice a week. To verify the effects of the program, this study conducted a pre-test and post-test of career maturity to analyze changes. In addition, the study qualitatively analyzed changes in the program activity sheets and process evaluation sheets per session. The results of the study are as follows: Firstly, the career exploration program based on the ecological system perspective conducted with the student at H. Meister High School improved the student's career maturity. Secondly, changes were observed in the scores in the sub-factors of career maturity between the pre-test and the post-test. Significant differences in the results of the analysis of the sub-factors of career maturity indicate that the program had a statistically positive impact on the career maturation process of the participant. In conclusion, as a result of the in-depth implementation of the program for 12 sessions, the participant expressed his desires which were clarified. In addition, a positive career maturation process appears to have taken place, owing to the self-directed program that led the participant to initiate plans and explore his career by himself. This study was conducted as a single case based on the ecological system perspective concerning career exploration and the career maturation process, but it will be necessary to expand the study to investigate the effects of group counseling, information exchange considering peer influences, common discussions on goal-setting, and other methods on the career maturation process.

This study aims at examining the effect of word-of-mouth communication through mini homepage on purchase attributes and mapping out a marketing strategy based on this. For this, it made an analysis of the communication level with 302 mini homepage users. The result showed that the communication level of information exchange has a positive effect on the purchase experience of food service products significantly, showing that the higher its level is, the more frequent its experience is. And it showed that the communication level of relationship retention has a negative effect on the purchase experience of food service products significantly, showing that the higher its level is, the less frequent its experience is. These results demonstrated the utility that can increase word-of-mouth communications through information exchange and relationship retention, given that they are used with the object based on the kinship of information exchange and relationship retention as word-of-mouth communications, and that they lay stress on the connection with other people in the mini homepage.
