하구는 담수와 해수가 만나 넓은 갯벌과 기수역을 형성하여 각종 생물의 서식지이자 어류의 산란지로 이용되는 생태학적으로 중요한 지역이다. 특히 한강 하구는 국내 4 대강 가운데 유일하게 하구둑이 설치되어 있지 않아 조수의 출입이 자유롭고 민간인 접근이 통제되어 있어 자연적인 하천지형과 기수역 생태계가 비교적 잘 보전된 구역이다. 본 연구의 모의영역은 한강 하류부로 상류 경계단은 행주대교, 하류 경계단은 전류단 수위표가 위치한 경기도 연천군 전곡읍 전곡 사랑교 부근으로 설정하였다. 지형자료는 한국건설기술연구원에서 2009년 8월 홍수사상 전 후에 대해 측량한 자료를 사용하였다. 한강 하구역에 대한 지형 격자를 구성하기 위하여 RAMS 전후 처리기인 RAMS-GUI를 사용하였으며, 구성된 지형 격자의 절점 수는 2,354개, 요소 수는 2,145개로 삼각요소와 사각요소가 혼용되어 있다. 구성된 격자망을 이용하여 2차원 하상변동 해석 모형인 SED-2D 모의를 통해 홍수사상에 의한 한강 하구부의 하상변동을 살펴보았다. SED-2D 모형은 미국 육군 공변단의 WES와 미 연방 도로국이 연계하여 개발되어 현재 국내외 2차원 하천해석에서 가장 널리 사용되고 있는 모형 중 하나이다. 하상변동 해석모형인 SED-2D를 통해 모의된 하상 변동량을 실제 측량된 홍수 전 후의 지형자료와 비교함으로써 모형의 성능을 분석하였다. 분석결과 SED-2D 모형의 경우 침식에 의한 하상변동이 모의되지 않았지만, 전반적인 하상변동 경향을 살펴볼 수 있음을 알 수 있었다.

While virtual field trips (VFT) are considered as an attractive alternative to traditional field experience, it is unclear how VFT are best used in Earth Science curriculum. In this study, we investigated the effects of flash panorama-based VFT on students' spatial visualization ability and their understanding of volcanic concept in high school Earth Science class. To investigate the effects of instructional treatment, we conducted pre and post-test on participants' spatial visualization ability and their understanding of volcanic concept, and analyzed using analysis of covariance (ANCOVA) and linear regression. Findings are as follows: First, the change in students' spatial visualization ability in experimental group was significantly higher than that of control group, especially in spatial manipulation category. Second, the change in students' understanding of volcanic concept in experimental group was higher than that of control group in most of the categories, but it is statistically not significant. Last, the change in correlation between spatial visualization ability and understanding of volcanic concept in experimental group was remarkably high compared to control group.

The purpose of this study was to identify the effects of brain wave change through therapeutic recreation programs on depression, sleep disturbance and quality of life among elderly with dementia. The subjects of this quasi-experimental study consisted of two groups, one experimental group (N=14) and one control group (N=18), after excluding 8 participants from a total of 40 participants. The subjects of experimental group were randomly selected from the elderly (order than 65 years old) of senior care center in Daejoen and participated in 3-month therapeutic recreation program. On the other hand, the subjects of control group did not participated in any therapeutic recreation program. Each group's pre-post brain wave change, depression, sleep disturbance and quality of life were estimated. Through ANCOVA and Analysis of Structural Equation Modeling with SPSS window 17.0 and AMOS 7.0, this study found followings. Frist, the therapeutic recreation program group indicated significant improvement of brain waves, sleep disturbance and quality of Life. In addition, depression was significantly reduced in the therapeutic recreation program group. Second, significant causal relationships was found among brain waves, depression, sleep disturbance, and Quality of Life.

This study is designed to find out the determinants of housewives' caregiving behavior to their elderly parents-in-law. For this purpose, a tentative path model, constructed with major socio-demographic variables in the caregiver's family as exogenous variables, is proposed to account for caregiver's behavior to elderly parents-in-law. The model is estimated with data collected from a probability sample of housewives in Kwangju, Korea. Estimation of the model, separately for caregiver's fathers-in-law and mothers-in-law, in terms of maximum likelihood(ML) procedures in LISREL8 reveals that housewives' educational attainment, father-in-law's age, father-in-law's health status, and family size have statistically significant causal. effects on care giving behavior to fathers-in-law, and that housewives' educational attainment, mother-in-law's age, family size, and caregiving attitude have significant causal effects on caregiving behavior to mothers-in-law. Comparison of the two estimated models indicates caregiver's educational attainment, caretaker's age, and family size are prominent determinants of caregiving behavior that can be commonly generalized to the two models. Except for these common determinants, however, a nonnegligible amount of differences is identified between the two models. The findings are discussed and interpreted with suggesting some salient theoretical and policy implications.

Objectives : This study was conducted to investigate differences in psychological characteristics between major depressive disorder (MDD) patients with and without suicide attempt using MMPI-2-RF. Methods : Subjects were 107 MDD patients who had visited the department of psychiatry of hallym university hospital and met the DSM-IV diagnostic criteria of MDD by the korean version of MINI-Plus 5.0.0. The patients were divided into suicidal attempters (n=43) and non-suicidal attempters (n=64) using C-SSRS. The one-way ANOVA was used to compare MMPI-2-RF scale scores between two groups. Additionally, ANCOVA was conducted considering the severity of depressive symptom and comorbidity as covariate. Results : Our results showed that Suicide/Death Ideation (SUI), Inefficacy (NFC) and Interpersonal Passivity (IPP) scales were significantly higher in the MDD patients with suicidal attempt compared to MDD patients without suicidal attempt (p<0.05). However, after controlling for the severity of depressive symptom and comorbidity, SUI scale showed a significant tendency (p<0.10). Conclusions : The result suggests that MMPI-2-RF scales could be a useful tool for identifying patients transitioning to actual suicidal attempts in the moderate or severe major depressive disorder group. Limitations of this study and directions for further research are also discussed.

Students with intellectual disabilities typically have great difficulties communicating their needs and wants and may get frustrated, anxious or show signs of aggressive behaviour. They are often unable to understand the concept of relationships with other people as well. This lack of social communication and interaction leads to poor motivation which increases other areas of difficulty in their lives. Therefore, to teach students with intellectual disabilities, it is essential to find special teaching methods to support their positive behavior. This paper proposes that special educational curriculum for students with intellectual impairments utilize natural environments(forests) and materials. The purpose of this study was to investigate the effects of Educational Programs Utilizing Forests on maladjusted behavior of students with mental retardation and to examine the positive effects of such planning practices. The subjects were middle school students who attended a special school for mentally-retarded students. They were divided into two separate groups- an experimental group and a control group. All subjects received the pre and post test using the same method. This program was applied to the formal educational process of middle school from March 1st to October 30th, 2009. In this experiment the results indicate that the effect of using a natural environment(forest) and the materials within a formal educational curriculum was positive as a type of horticultural therapy and that it supports positive behavior strategies in students with intellectual impairments. The usage of various natural materials including plants and flowers within the natural environments provide students with increased opportunities to participate. Teaching methods including natural materials help teachers engage with their students more easily during routine activities as their interest is already stimulated. This project will help students with intellectual impairments to build skills which enable effective participation and increase independence throughout their lives. This should be embedded into both routine and planned activities of the classroom Also, it offers a needed interior plan for the treatment space through an analysis of psychological factors of how the environment affects students.

The purpose of this study was to analyze the effects of instruction using science history on science achievement and attitude of students. A pretest-posttest control group design was employed. Subjects were comprised of 193(males 114, females 79) first grade middle school students. A control group of 94 students was instructed using traditional teaching methods and an experimental group of 99 students was instructed using the history of science. Two groups were taught 15 lessons during a 9-week period. To analyze the data statistically, an analysis of covariance(ANCOVA) was applied. The experimental group was significantly different from the control group inrespect to science achievement. There was no significant difference in science achievement between the two groups according to gender. Analysis results on the attitude towards science found the experimental group to significantly differ from the control group. There was no significant difference in attitudes towards science between the two groups according to gender.
