Purpose: Ego-integrity in older adults is the central concept related to quality of life in later life. Therefore, for effective interventions to enhance the quality of later life, a scale to measure ego-integrity in older adults is necessary. This study was carried out to develop a scale to measure ego-integrity in older adults. Methods: This study utilized cronbach's alpha in analyzing the reliability of the collected data and expert group, and factor analysis and item analysis to analyze validity. Results: Seventeen items were selected from a total of 21 items. Cronbach's alpha coefficient for internal consistency was.88 for the 17 items of ego-integrity in the older adults scale. Three factors evolved by factor analysis, which explained 50.71% of the total variance. Conclusions: The scale for measuring ego-integrity in Korean older adults in this study was evaluated as a tool with a high degree of reliability and validity.

Background and Objective: Coptidis Rhizoma is a medicinal herb known for its antioxidant and anti-inflammatory effect. The purpose of this study was to examine the effects of CR on the experimental burn elicitation in vitro and in vivo. Material and Methods: In order to know the antioxidant effect on skin cell of mice after burn elicitation, superoxide dismutase (SOD) activity was measured. In vitro, the RAW 264.7 macrophage cells were treated with lipopolysaccharides for experimental inflammation. iNOS mRNA expression was observed after CR-treatment. In order to know effects on the skin regeneration in the burned mice, we counted the nitric oxide (NO) in blood. We also observed the histological structure in the epidermal basal layer and the dermal section, and we studied changes of angiogenesis in the capillaries surrounding the basal layer and dermal papilla. The changes of transcription of iNOS mRNA (inducible nitric oxide synthase mRNA) and changes of NF-${\kappa}$B (nuclear factor ${\kappa}$B) p65 positive reaction were also observed to investigate the changes of the stress in the skin. Results: The results indicated that CR has significant effects on the antioxidant effect on skin cells of mice after burn elicitation by increasing SOD activity in the in vitro test. It seemed that CR decreased the amount of NF-${\kappa}$B which induced the iNOS mRNA dose-dependently and suppress activating NO and angiogenesis. Furthermore, CR facilitated the process of skin recovery after experimental burn. Conclusion: CR can be applied for burned skin via antioxidant effect and skin regeneration.

Purpose: The purpose of this study was to compare the needs of case management between Medical aid beneficiaries with simple and multiple chronic diseases (SCD vs MCD). Methods: The study employed secondary analysis method using a cross-sectional data from 2009 case management service enrollees. Data on 35,862 beneficiaries who have chronic disease(s) were used in the description of chronic disease characteristics, and data on 20,392 beneficiaries, excluding those who have depression and/or disabilities, were used to compare the group differences. Results: Mean age was $68.8{\pm}11.63years$, and 73.3% were females. MCD group showed an older age, had more women than SCD group. Self-care ability and appropriateness of health care utilization were significantly different between the groups, but there was no difference in health-related quality of life. In subscales, there were significant differences in general health status, depression, symptom management, healthy lifestyle, hygiene and vaccination, and appropriateness of health utilization. Conclusion: Different characteristics between patients with simple and multiple chronic diseases indicate that different case management approaches are required for these groups. The study results could be used as a basis for the development of case management model tailored to the characteristics and needs of medical-aid beneficiaries.

Objectives : After analyzing the proficiency of medical communication of the students in College of Korean Traditional Medicine using standardized patients, we suggests ways to improve clinical practice in the future class and medical communication curriculum development. Methods : 20 students before clinical practice class (3rd grade) and 20 students after 1 year clinical practice class (4th grade) participated and did their medical interview on Standardized patient. They were evaluated on patient-physician communication skills by standardized patients and professor evaluator. In addition to be evaluated on patient-physician relationship, medical interview skills by professor evaluator. Results : As follows in the evaluation of clinical practice with standardized patients 1. More than half of the participated students regardless of their grade received poor score in their medical communication evaluated by SP(Standardized patient) and PE(Professor evaluator). 2. Greeting, History taking parts were higher in the 4th students who received 1 year clinical practice class, but verbal-nonverbal response, voice tone parts were higher in the 3rd students who do not received clinical practice lesson. 3. Pronunciation&Voice tone parts were higher in the male students but, gathering information part was higher in the female students. Conclusions : We think that the current clinical practice lessons are insufficient as a way to learn and improve medical knowledge and medical communication skills, and it is necessary a new form of clinical practice class. Participatory lesson using standardized patient could be a good alternative of that in the future class.

The purpose of this study was to analyze the characteristics of science gifted students who participated in science gifted activity using rainbow. For this purpose, the science gifted activity using rainbow was developed and applied to 23 seventh grade science gifted students. The results indicated that gifted students had various concepts and ideas of optics. For example, some gifted students thought that there was rainbowshaped light at the place of rainbow, and another considered the process of dispersion of light in a waterdrop would be same as the process of the dispersion in the prism. Also, various rainbow theories and scientific imagination of gifted students were found. For devising new rainbow, gifted students used two strategies, 'changing the features' and 'changing conditions'. In addition, we discussed effective methods of applying this activity and implications to science gifted education.

The purpose of this study was to investigate the purchasing behavior and selection attributes for Home Meal Replacement (HMR) and to identify the selection attributes affecting purchasing frequency and purchasing costs of married women living in a city. Among 837 questionnaires distributed to HMR married women consumers, 752 complete questionnaires (89.8%) were analyzed. The younger married women group showed higher frequency of purchasing HMR than the older age group. The 20s and 30s age groups showed higher purchasing costs for HMR than the 40s and older age groups. A higher proportion of employed married women purchased HMR three or more times per week and spent an average of more than 20,000 won per purchase in comparison with unemployed married women. HMR selection attributes were classified into five factors: 'taste and sanitation', 'economic efficiency', 'health and nutrition', 'convenience', and 'reliability and awareness'; mean scores of these factors' importance levels were 4.28, 3.93, 3.59, 3.54, and 3.50 out of 5 points, respectively. The importance level of 'taste and sanitation' factor was significantly greater as married women's age decreased. However, the importance level of 'health and nutrition' factor was significantly greater as married women's age increased. The results of the logistic regression analyses indicate that the 'taste and sanitation' and 'health and nutrition' factors affected frequency of purchasing HMR. The 'reliability and awareness' factor had the most significant impact on cost per purchasing HMR. Therefore, a product differentiation strategy according to married women's age and employment status should be applied. Product qualities and brand value should be improved to enhance competition in the HMR market.

Using the data of three environmental monitoring sites in Pohang area(KME112, KME113, and KME114), statistical forecasting models of the daily maximum and mean values of PM10 have been developed. Since the distributions of the daily maximum and mean PM10 values are skewed, which are similar to the Weibull distribution, these values were log-transformed to increase prediction accuracy by approximating the normal distribution. Three statistical forecasting models, which are regression, neural networks(NN) and support vector regression(SVR), were built using the log-transformed response variables, i.e., log(max(PM10)) or log(mean (PM10)). Also, the forecasting models were validated by the measure of RMSE, CORR, and IOA for the model comparison and accuracy. The improvement rate of IOA before and after the log-transformation in the daily maximum PM10 prediction was 12.7% for the regression and 22.5% for NN. In particular, 42.7% was improved for SVR method. In the case of the daily mean PM10 prediction, IOA value was improved by 5.1% for regression, 6.5% for NN, and 6.3% for SVR method. As a conclusion, SVR method was found to be performed better than the other methods in the point of the model accuracy and fitness views.

The purpose of this study was to analyze the characteristics of multiple-choice test items used in assessment of high school integrated science according to 2009 revised curriculum. For the analysis of the tendency of item setting, we devised an analytic framework specific to integrated science, and analyzed the characteristics of items by applying the devised framework and item response theory. The results of the tendency of item setting revealed that most of items run counter to the intent of integrated science in terms of item resource, integration extent, and cognitive level, which means teachers are stick to separative method in teaching-learning and assessment of integrated science. The results of the analysis applying item response theory showed that item difficulty was appropriate and item discrimination was considerably high. However, there was no relevance between the tendency of item setting and qualitative characteristics of the items. We also discussed some agendas to improve the teaching-learning and assessment of integrated science based on the results of this study.
