한국 특산종 C. longicolpus의 지리적 변이를 조사하고자 discriminant function 분석에 의한 형태적 변이 그리고 전기영동법에 의한 유전적 변이를 전국적으로 조사하였다. 11개 집단의 discriminant function분석결과 11개 집단은 형태적으로 뚜렷한 차이 없이 유사하였다. 13개 집단의 유전적 변이를 조사한 결과는 13개 집단 평균 A = 1.37, P = 29.96%, HD = 0.076 및 HG = 0.083으로 일반적인 담수어류의 종내 집단 간 평균 유전적 변이정도보다 다소 높게 나타났다. 평균 유전적 근연치는 5 : 0.88으로 타 어종의 일반적인 집단 및 유전적 근연정도와 유사하였다.

본 연구에서는 SNS 품질요인에 대한 기존 연구에 대해 전문가 집단이 산출한 각 품질요인에 대한 중요도와 사용자 집단이 각 품질요인에 대해 중요하다고 생각하는 중요도의 차이를 알아보고자 하였다. 연구를 위하여 선행연구에서 사용된 SNS 품질요인을 시스템품질, 정보품질, 인터페이스품질, 서비스품질로 구분하여 AHP 기법을 적용하여 전문가 집단과 사용자 집단의 품질요인별 중요도를 실증 분석하였다. 분석결과 전문가 집단과 사용자 집단의 각 품질요인에 대한 중요도의 인식 차이가 나타나는 것으로 나타나 품질평가에 있어 전문가와 사용자의 의견을 종합하는 종합 평가가 필요할 것으로 사료된다.

컴퓨터의 보급이 보편화 되면서 컴퓨터 보유 가정이 기하급수적으로 증가되고 있다. 이로 인하여 컴퓨터로 할 수 있는 일이 늘어나고, 활용분야 역시 다양해지고 있다. 특히 과거의 교수-학습 방법과는 달리 최근에 많은 분야에서 연구되고 있는 E-러닝, ICT, 컴퓨터 활용, 인터넷 등을 접목하여 학생들의 협동심과 책임감을 요하는 협동학습에 적용하고자 하는 연구가 진행 중이다. 그런데, 협동학습의 집단은 크게 인문계열, 실업계열 고등학생 집단과 중학생 집단으로 분류한다. 따라서 본 논문에서는 컴퓨터를 활용하는 정도와 이용시간 등을 학습에 얼마만큼 도움이 되는지 분석하고, 계열별로 집단을 구분하여 학생들의 집단에서 개인의 적극성과 참여정도에 대한 영향이 집단 전체에 미치는 파급효과를 분석한다. 마지막으로 학업성취에 대한 학생들의 성적차이의 관점을 분석하고, 성별에 따른 학업성취도 차이, 주변 환경에 따른 영향력의 정도, 협동학습의 결과 학업성취도의 변화를 평가한다.

The purpose of this study was to investigate the kinds of native and prohibitive foods in Hansan-Do area. The kinds of the prohibitive foods and the reason prohibiting those from pregnant or lactating woman, fisherman and sick people were surveyed by using a guestionnaire from 1994 to 1998. The results showed that Chungmu Gimbab was perceived highly as a native foods and the reason for prohibiting specific foods was not based on scientific evidences.

The purpose of this study is to investigate how Korean EFL university students acquire an understanding of English tenses. To research this, we proposed two research questions of study as below. Firstly, what difference is there in English tense acquisition between an experimental group and a control group? Secondly, what difference is there in the English tense acquisition according to English proficiency? The subject of a sample survey was a 39 student experimental group and a 38 student control group, total 77 students, who take English courses as a required subject at 'C' university in Gwangju. The data needed for this study was obtained by the questionnaires with 40 questions about the English tense. The data analyzing method was t-test through the statistics program SPSS 12.0. There was a significant difference between the experimental group's tense acquisition ability and the control group's, even though low group showed no significant improvement in their tense acquisition ability. Studying English tense through reading led the students to be present in classes with interests, so the experimental group showed more academic accomplishments than the control group.

Objectives：This study was conducted to investigate the diagnostic utility of the Rorschach schizophrenia/depression/coping deficite index in child-adolescent parent groups(schizophrenia, depression,depressive conduct disorder). Methods：Three child-adolescent parent groups(schizophrenia(18), depression(20), depressive conduct disorder(19)) were individyally assessed using the Rorschach test and schizophrenia/depression/coping deficite index scores were analyzed. Results：The results showed significant difference among three groups on only SCZI and significantly higher SCZI score of schizophrenia group than other two groups. When the critical value of SCZI was 4, diagnostic hit rate was 96.5%, and when the critical value of DEPI was 3, diagnostic hit rate was 57.9%, and when the critical value of CDI was 4, diagnostic hit rate was 66.6%.

The purpose of this study was to examine and analysis self-help group program performed in community-based home visiting health service. The data was collected public servants from the Home Visiting Health Care Service of 253 public health centers all over the country and was analyzed by SPSS/Win 17.0 program. 43.1% of self-help program was performed and 56.9% was not from year 2007 to 2010. As the years passed, the number of self-help group program was getting increased. The action for activating self-help programs was voluntary participation of clients, enthusiasm of management practitioner, and encouragement about self-help group. Self-help group programs based on public health center are insufficient. Self-help programs should be activated for clients of home visiting health care service. A systematic operating model of self-help group is also needed to develop and apply in consideration of these findings.

In recent years, collaborative learning in university courses has been emphasized in order to improve collective intelligence. Based on literature reviews, individual creativity was used as a variable of personal characteristic, team trust and collective efficacy were used as variables of teams to see the relationship with collective intelligence as a variable of learning outcome. Data were collected from 770 students from A University in Gyeonggi-do, H University in the Daejeon, and K University in Chungcheong-do, and analyzed by using structural equations modeling. As results, individual creativity had significant influence on collective efficacy and collective intelligence. Team trust also had significant influence on collective efficacy and collective intelligence. In addition, collective efficacy had a positive effect on collective intelligence. This study will be able to utilize basic data for establishing instructional design and strategies of collaborative learning in the universities.

In this paper, the elementary students from the Information class of the Science Education Institute for the Gifted were divided into the experimental and control groups. The two groups took Scratch programming classes and the changes in their sociality were analyzed. The experimental group used the Scratch remix function, an educational programming language, to perform the LT cooperative learning. The control group took general instructor-led classes. The experimental group carried out a team project in which learners should cooperate with each other to produce certain results using the remix function. Twelve 3-hour lessons were taken by the experimental and control groups consisting of 30 and 30 students respectively to verify changes depending on remix-based cooperative learning. According to t-test using the survey results, the experimental group that performed cooperative learning using the Scratch remix function showed more improved sociality than the control group did. There was a statistically significant difference as well.

Molecular relationship and genetic diversity of 21 wild tea collections which grown natural region in Korea were investigated based on PCR-RFLP analysis using DFR genes. Approximately 1.4kb fragment of the DFR gene from wild tea samples were successfully amplified use DFR 4+5 primer pair. On the bases of restriction fragment length polymorphism(RFLP) analysis using Hpa II and Mse I enzymes, three different band patterns shown from Hpa II enzyme and showed genetic diversity between same region wild tea group. Six kind of restriction enzyme profiles obtained from digested with restriction endonuclease Mse I and shown two kind of restriction enzyme profiles collected from same region wild tea at Ungpo. The results of RFLP analysis indicated that wild tea showed genetic diversity among different regions of tea groups, but also between same region wild tea.
