The purpose of this study is to convergence approach analyse the depression tendency by family situation and leisure history in the elderly who live in town house in Gyeonggi-do. This study analysed factors such as family situation, leisure history related to the depression tendency. This study selected 20 elderly people over 65 as research subjects and all data analysis was to conduct analyze by multi-variables independent t-test and one-way ANOVA. The results of GDS showed 11 people(55%) presented with mild depression tendency(M=13.0) and 1 person(5%) showed severe depression tendency. 11 out of 30 questions in GDS had a significant difference among the depression degree. Individual disease type had a significant difference in depression tendency statistically(F(3, 16)=4.534, p<.05). Past leisure satisfaction among total leisure history factors had a significant difference in depression tendency(F(2,17)=3.989, p<.05). The participants whose leisure activity was absent in the past and present showed a regressive depression tendency. Participants with no social companions also presented with the same. The study concluded to grasp the real condition of depression, and make practical alternatives for that, multilateral depression tendency analysis using diverse methods are necessary in the near future for improving reliability of tools.

The purpose of this study is to analyze high school students' understanding levels about earth science terms written in Chinese characters according to learners' characteristics. In order to investigate how the responses vary according to their characteristics, first of all, proper scientific terms are selected, and then corre sponding questions about them are offered as subjects, which consists of a Korean characters type, a picture type, and a Korean and Chinese characters type. During paper test and interview, the questions are given to fifteen students from general high schools in Jecheon, Chungbuk Province. The results of the study are as follows; Students in formal operation level and field-independency answered very well and also the terms of Chinese characters type and picture type improve the students' understanding and memorization. Generally, Chinese characters have more positive influence on their learning than the negative. Therefore, in general, it seems that it's more effective to explain the sound and meaning of terms in detail and to give learners enough time to draw a picture about each term by themselves when scientific terms are delivered to students in Chinese characters in class.

Objectives: Angiotensin-converting enzyme (ACE) gene polymorphism has been reported to be associated with depression and therapeutic outcome in depression. The purpose of this study was to determine whether ACE gene polymorphism is associated with seasonal variation in mood and behavior in a young Korean college student sample. Methods: 297 young Korean medical students were recruited in this study. All subjects were free of major medical and psychiatric problems. They were genotyped for the ACE gene polymorphism and evaluated the seasonal variation in mood and behavior by the Seasonality Pattern Assessment Questionnaire (SPAQ). Results: Global Seasonality Score (GSS) of SPAQ between three genotypes were not different. However, comparison of the group that showed seasonality of mood and behavior during winter with the group that did not showed seasonality indicated significant difference in genotype distribution ($x^2=6.79$, p=0.034). The D allele non-carrier (ll genotype) frequency was significantly higher in winter seasonality group than non-seasonality group ($x^2=6.59$, p=0.010；odds ratio [OR]=2.27, 95% confidence interval [CI] 1.20-4.28). Conclusion: These results suggest that the ACE gene polymorphism is related to winter-type seasonality in a Korean population.

The purpose of this study was to survey the secondary science teachers' viewpoints of basic particles conceptions addressed in science course. The first content of this study was to analyze the secondary science teachers conceptions related to basic particles founded on scientific history viewpoints. The second content was to investigate their understanding of relations between atom, element, and molecule concepts. The third content was to search the factors influenced on basic particles conceptions of science teachers. For this study, 96 secondary science teachers were selected. The data of this study were collected through a questionnaire developed for this study and were analysed using the method of constant comparative analysis. The results showed that their viewpoints towards basic particles were similar to each other regardless of their majors and their conceptions belonged to the past viewpoints. The teachers lacked linking understand among basic particles conceptions because they applied different viewpoints on different problems. Most of the teachers were influenced on science textbooks, guidebooks for teachers, and reference books to form confusing viewpoints of basic particles.

Objectives：Assessment of sleep disturbance is an essential part of the diagnostic criteria used for several psychiatric disorders. Change in sleep patterns over time may indicate response to treatment. In clinical practice, sleep is usually evaluated subjectively by patient self-report. This study was aimed to compare subjective sleep assessment with objective sleep measurement by actigraphy in psychiatric inpatients. Methods：A total of 32 psychiatric inpatients were studied. Patients were asked to wear a wrist actigraphy for three consecutive days and nights and to fill out a sleep log each morning. The severity of depression and anxiety was evaluated according to Beck Depression Inventory and State-Trait Anxiety Inventory on the first day of the study. The subjective level of satisfaction with quality of sleep was also evaluated according to visual analog scale. Nurses assessed sleep at one hour interval between 10:00 PM and 6:00 AM for three consecutive nights. Results：There was statistically significant difference of sleep latency between patient's sleep log and acti-graphic measurement. Nursing reports were more consistent with actigraphic measurement than sleep log. Interestingly, subjectively poor sleepers show no significant difference in sleep parameters compared with those of good sleepers. Subjectively poor sleepers report longer sleep latency than that of actigraphic assessment. The discrepancy between subjective and objective assessment of sleep latency was significantly correlated with scores of Beck Depression Inventory and State-Trait Anxiety Inventory. Conclusion：These results show that there are discrepancies between subjective and objective assessment of sleep. The discrepancy of sleep assessment could be influenced by severe depression and anxiety. Especially objective sleep measurement is needed to assess sleep in psychiatric inpatients with severe depression or anxiety and the subjectively poor sleepers for more reliable measurements.

The purpose of this study was to understand science teaching experiences of elementary school teachers who taught the system thinking-based science inquiry class. The phenomenological methods were applied to analyze four elementary teachers' meaningful experiences. The four step methods of phenomenological experience research proposed by Giorgi (1985) and interview questions developed by Seidman (1998) and Schuman (1982) were used in order to collect qualitative data. The major findings of this study were as follows: First, teachers intentionally tried to ask divergent thinking questions which promoted the system thinking in classes. The teachers used divergent thinking questions to promote their students' thinking activities and to induce students' system thinking. In addition, the receptive mood created by teachers and interactive environments had a positive effect on promoting system thinking skills. Second, teachers remarked lack of teaching and learning materials and difficulties in selecting themes of their classes in order to teach the system thinking-based science inquiry class effectively. In addition, it was very difficult for teachers to evaluate the contents and processes of students' learning correctly because there were little evaluative tools and methods readily available. The findings indicated that there were some limitations in maximizing the effects of system thinking-based science inquiry instruction due to elementary students' inappropriate process skills of inquiry activities. Findings of this study revealed significant insights about elementary school teachers' experiences regarding the system thinking-based science class.
