  • Objectives : This study was aimed to investigate stress and coping strategy in the families of schizophrenic patient, and changes of knowledge, stress and coping strategy after brief program of family education compared with control group Methods : The education group consisted of twenty four people who were families with schizophrenic patients and attended the brief program of family education. The control group consisted of twenty two people with schizophrenic inpatients. Self-report questionnaires such as Family Coping Questionnaire(FCQ), Patient Rejection Scale(PRS), Worry Questionnaire, Knowledge Questionnaire, Beck Depression Inventory(BDI), and State-Trait Anxiety Inventory(STAI) were administered to the education group and the control group, twice at the pre-test and post-test. Results : 1) In the education group, scores of worry questionnaire, BDI and STAI-S at the post-test were significantly lower than those at the pre-test. Social interests score of FCQ and knowledge questionnaire score at the post-test were significantly higher than those at the pre-test. In FCQ factors, social interests associated with avoidance strategy score at the post-test was significantly higher than that at the pre-test. However, in the control group, there was no significant difference in all questionnaires. 2) In the education group, significant positive correlation existed between calculated differences of worry questionnaire and STAI-S, and between worry questionnaire and STAI-T, whereas significant negative correlation existed between positive communication of FCQ and PRS, and between knowledge questionnaire and STAI-S. In the control group, significant negative correlation existed between information of FCQ and PRS, and between positive communication of FCQ and PRS. 3) In the education group, significant positive correlation existed between calculated differences of worry questionnaire and age of patient, whereas significant negative correlation existed between knowledge questionnaire and duration of illness. However, in the control group, there was no significant correlation. Conclusion : The brief program of family education was effective in increasing knowledge about schizophrenia, decreasing worry and anxiety about the patients in families with schizophrenic patient. In the education group as knowledge about schizophrenia increased, anxiety about schizophrenic patient decreased, but there was no significant correlation in the control group. As relative's rejection feeling about schizophrenic patient decreased, positive communication strategy increased in both groups. However, the control group was more affected by rejection feeling than the education group.

  • 본 연구에서는 댐 운영 전과 후의 유출 특성 변화를 평가하는 데 베이지안 기법을 이용하였다. ROM과 같은 댐 운영은 자연유량(유입량)에 대해 주어진 방법을 적용하여 수행하는 일종의 조정(수정) 과정이다. 이 과정은 무작위 변량에 해당하는 유입량을 대상으로 하며, 그 과정의 결과로 역시 유출량이라는 무작위 변량이 생성된다. 기 확정된 또는 고정된 조정(수정) 과정은 일정한 함수로 표현 가능하다. 결과적으로 이 과정은 사전확률에 우도함수를 적용하여 사후확률을 유도하는 것과 같다. 즉, 베이지안 기법의 적용과정과 다르지 않다. ROM으로는 일정률, 일정량, 일정률-일정량 ROM(Rigid ROM) 세 가지를 고려하였다. 각 ROM별 방류 특성을 고려하여 우도함수를 결정하면, 베이지안 기법을 적용하여 사후분포, 즉, 방률량의 분포함수를 유도할 수 있다. 베이지안 기법을 적용하여 유도된 결과는 ROM을 적용하여 직접 모의한 결과와 비교함으로써 검증된다. 본 연구에서는 대상 댐으로 안동댐을 선정하였으며, 안동댐에서 관측된 2010년부터 2019년까지의 10년치 유입량 자료를 이용하였다. 즉, 2010년부터 2019년까지의 안동댐 유입량 자료는 댐 운영 이전의 유출특성을 대변하고, 모의된 유출량은 댐 운영 이후의 유출특성을 대변한다.

  • The evaluation systems on the National Spatial Information Policy(NSIP) has been changed, since the Establishment and Use of the National Geographic Information System Act(NGIS Act, 2000) was abolished and the National Spatial Data Infrastructure Act(NSDI Act, 2009) was enacted. As compared to the NGIS Act, the policy evaluation systems for National Spatial Information are regarded as unified and centralized. However, some argue that the claim of budget and the legal feasibility of the NSIP was weakened. Given the different views on the two laws, this study aims at analyzing the changes in the evaluation system by comparing the NGIS Act and the NSDI Act. A Comparative Analysis framework is employed. The subjects of the comparative analysis are evaluation mechanism, evaluator, evaluation target and range, after-assessment utilization, and agent. In order to improve the effectiveness of the evaluation system, it is recommended that the clarification of evaluation purposes, institutional enhancement for evaluation agency, the development of evaluation indexes, the combination of top-down approach and bottom -up approach, and the increased linkage between budget and evaluation result.

  • Purpose: The aim of this preliminary study was to evaluate the effect of Problem-Based Learning (PBL) curriculum on development of comprehension of basic medical knowledge and quality of semi-structured problem solving including scientific reasoning skill. This scientific reasoning contained five components including: size of simple, design of research cause-effect, construction of risk factor, analysis statistic of data, interpretation of result. Materials and Methods: Seoul National University Dental students (100) participated in this experience during two weeks, 2004. Forty eight multiple-choice questions (MCQ) concerned "Infection Control and Prevention" were asked before and after two sections of Lecture-Based Learning (LBL) and PBL (pretest-posttest control group design). A semi-structured problem in epidemiological research was asked to these students after two sections (posttest-only control group design). Data (mean and SD) were analysed using the t Test for two independent samples (p<.05), comparing PBL versus LBL. Results: Our analyse of scores show no difference between LBL and PBL in the development of comprehension of "Infection Control and Prevention". The quality problem solving (epidemiological research) was significantly different between the two groups (p=.029); specially, two components' scores of reflection on scientific reasoning cause-effect (p=.000) and interpretation of result (p=.001) were significantly better for PBL than for LBL. Conclusion: Theses results indicate that comparing LBL and PBL, PBL curriculum have not been disadvantaged in comprehension of basic knowledge, and have contributed to develop the scientific reasoning in problem solving.

  • This study was developed to evaluate the effectiveness of a multicultural education program for college students. To this end, the program was designed to offer them a series of twenty lectures for three months, 60 hours in total, and a quasi-experimental design was employed to evaluate the difference between pre-test and post-test scores of participants of both experimental group(N=45, Mdiff=.378) and control group(N=47, Mdiff=.036) on their attitudes on cultural diversity. Also, pre-test and follow-up test scores were compared to confirm whether the effect was sustained. The results showed that while the pre-post difference was statistically significant for experimental group participants(t=4.264, p=.000), the difference was not significant for control group students. Furthermore, the effectiveness of the program was sustained among students in the experimental group at a 3-month follow-up test(t=2.466, p=.016). In conclusion, the multicultural education program, in fact, proved to be effective in changing the attitudes of college students in understanding and accepting different cultures in Korean society.

  • The English language listening environment in Korea nowadays is situated in a quiet and artificial state rather than one of natural exposure. The purpose of this study is to investigate the effectiveness of convergence for pronunciation and listening activities using English advertisements. A survey sample of 40 students was chosen for this study. These 40 students successfully answered the questionnaire and took a 3 hour English course as an elective. Pre and post surveys tests were done for listening ability and learning interests. For the listening tests, TOEIC L.C. test were used and survey questions about interests made by Sunhee Park were revised to be proper used. The results of this study show a positive impact on TOEIC listening ability and that students are able to listen and naturally pronounce more successfully through convergence using English advertisements with higher learning motivation.

  • While the number of crashes and fatalities has decreased for the last few decades, the proportion of elderly-involved crashes has continuously increased from 19.5% in 2001 to 29.6% in 2008. This paper aims to evaluate the effectiveness of traffic safety education to seniors, which has been conducted for the purpose of providing more systematic knowledge such as safety regulations and making the elderly more aware of the risks of crashes, and eventually to reduce elderly-involved crashes. First, we investigated the levels of traffic safety knowledge of the elder people who attend senior community centers and social welfare centers in Seoul and provided traffic safety education. Then, the effectiveness of traffic safety education was evaluated by using the before-and-after analysis. We set up two different groups to improve the reliability of evaluation: one for control group and the other for comparison group. The results showed that the average scores of the control group after education were significantly improved at the 95% significance level compared to the average scores before education, whereas the comparison group did not show a significant differences in the average scores before and after education except for two questions. This indicates that the levels of traffic safety knowledge of the control group have been improved through education and therefore, the safety education seem to be effective to some extent.

  • Objective: The purpose of this study was to examine the effects of an occupational therapy intervention program of arts and crafts on the activities of daily living and quality of life of outpatients after a stroke. Methods: Using an experimental pretest-posttest control group design, we conducted the following with ten participants diagnosed with stroke: one retest session, 10 intervention sessions, and one posttest session. MMSE-K (Korean version of the Mini-mental State Examination), COPM (Canadian Occupational Performance Measure), and WHOQOL-BREF (The World Health Organization Quality of Life-BREF) scores were obtained before and after the intervention. The results were analyzed using descriptive and nonparametric statistics. Results: As a result of comparing the pretest-posttest scores of the experimental and control groups, there was no significant difference in K-MBI score improvement in terms of activities of daily living. There was a significant difference in COPM scores between the experimental and control groups. There was a significant difference between the WHOQUP-BREF scores of the experimental group before and after the experiment, as well as between the groups. Conclusions: The results suggest that an arts and craft group occupational therapy intervention program for stroke patients may have a positive impact on activities of daily living and quality of life. Although an arts and craft group occupational therapy intervention program appears to be a promising approach, further studies are required to confirm these findings.

  • This study was investigated to examine the effects of writing activities based on Polya's Problem Solving Stages on Learning Accomplishment and Attitudes. A total of 54 students were selected from two Grade 6 classes of P Elementary School in G City to form an experimental group(n=27) and a control group (n=27). The experimental group was applied to a class which was creating writing activities according to Polya's Problem Solving Stages to problem solving and inquiry activities. The control group was taught by the traditional method to the same activities. The five questions for each area were selected as a descriptive assessment of the second semester of Grade 5 in the area of the Academic Achievement pre-test, developed by the G Education and Science Research. The post-test was selected by a descriptive assessment of the content of the first semester in Grade 6. The same questions were posed for both the pre-test and the post-test of the Mathematical Attitudes assessment. We examined the pre-test at the beginning of the school term, then the students were re-examined after one semester, using the same questions as the pre-test. This research showed that there was a meaningful difference in Learning Accomplishment as a result of T-test in the 5% level of significance. Secondly, there was a meaningful difference in the Mathematical Attitudes as a result of T-tests. It shows that writing activities based on Polya's Problem Solving Stages have an influence on improving Learning Accomplishment and Attitudes.

  • The purpose of this study is to investigate the influence on respiration, oral motor and articulation using wind-instrument centered music therapy for patients with cervical cord injury who need continuous train of respiratory muscle. Three patients with cervical cord injury who needed continuous training of respiratory muscle were selected and post data was analyzed. The harmonica using both exhalation and inspiration was selected as an wind-instrument. Each session was taken 30 ~ 40 minutes, once a week from total 6 weeks with small group. Material about every session's work was provided for individual to maintain practice after program. Oral motor and articulation test was done to assess reflecting features of maximal expiratory flow and wind-instrument of factor related breath. Maximal expiratory flow has increased by average 25ml more, articulation has increased by 3.16 points more and the movement of oral motor has increased 11.67 points more than pre-test from the analyzation. In the comparison of the details, the increase of oral motor function was confirmed from scores on the jaw and tongue except for the lips. Based on the results of this study, this study suggests that wind-instrument centered music therapy will be a practical and effective intervention for respiratory rehabilitation in patients with cervical cord injury.
