This study investigated the effectiveness of home economics class on self-esteem and stress of middle school students. Data were collected from self-reported inventory of the middle school students in Y city of Gyeonggi province and 165 data copies were used for analyses. Data were analyzed for frequency, percentage, mean, standard deviation, Cronbach's ${\alpha}$, t-test, corelation and dependent t-test using SPSS/PC 18.0 program. The results were as follows. First, the average of positive self-esteem was 2.74 and that of negative self-esteem was 1.90 on a 4 Likert scale. The range of stress level was 1.88~2.48 on a 5 Likert scale. Life satisfaction was 3.90 and helpfulness of home economics class was 3.89 on a 5 point Likert scale, which means moderately high. Second, examining differences in variables according to gender, there were statistically significant differences in stress regarding family for both pre- and post-tests. Third, helpfulness of home economics class had positive correlation with positive self-esteem and life satisfaction and had negative correlation with negative self-esteem and stress, which means that home economics class enhance life satisfaction and positive self-esteem and lessen negative self-esteem and stress of middle students. Fourth, as a result of comparison of pre and post-tests, positive self-esteem, life satisfaction, and helpfulness of home economics class increased statistically after home economics classes, while stress regarding school life decreased statistically. Even though students' growth and changes resulting from learning other subjects were not controlled, it was meaningful that effectiveness of home economics class were examined and helpful information for enhancing perception of home economics education were provided.

This study was designed to make an analysis of the content related with Korean traditional food culture covered in the section of Food and Nutrition of Home Economics textbooks based on the current 7th curriculum and to investigate the recognition and needs for education on Korean traditional food culture among high school students. Through this, we tried to present basic data contributing to the construction of practical educational content and educational method in relation to Korean traditional food culture. The results of this study are as follows. The content of Korean traditional food culture in the section of Food and Nutrition covered by Home Economics textbooks consisted of 'Setting the Table and Table Manners' for the third graders of middle school, 'Planning and Preparing Invitation and Events' for the freshman of high school, and 'Food Culture and Preparation of Food' for the second and third graders of high school. High school students were proud of themselves on Korean traditional food culture, but fail to apply their knowledge to real household life. In particular, it was proved they didn't understand' Korean Festival Holidays and Annual Customs: The need on the content of Korean traditional food culture showed significant difference in accordance with pride on traditional food culture, its succession in the families and one's recognition. And it was highly correlated with the subordinate variables such as demands, interest, utilization. These results showed that the education of Korean traditional food culture is an area that is demanded and how to cook Korean traditional food should be included in the content for education and practice of cooking and experience of food culture should be dealt with as the educational methods.

The purpose of this study was to identify whether the elementary school students force conceptions may influence on designing tools experiments. Four questions with multiple choices and reasons for those choices were asked to identify scientific/alternative force conception. Also four tasks for tools experiments matched to each force conceptions were developed into open questions in hypothesizing. controlling variables and methods of experiments. Forty elementary students were selected from 4 classes in sixth grade of a school in Daegu city. The major findings of this study were that the types of force conceptions can be classified into scientific and alternative conceptions. The patterns of designing experiments could be identified with types of hypothesis, controlling variables and methods of experiments in each four tools experiments. But students those who had scientific force conception did not better in hypothesis, methods of controlling variables and results for simple experiment than those who had alternative force conceptions. These results imply that students' force conception did not influence on designing tools experiments. The assumption that scientific conception could improve designing experiments was not guaranteed by this results.

The purpose of this study was to examine the mediating effects of paranoid tendency and social isolation in relationship between covert narcissism and Tajin Kyofusho(TKS). We administered self-report questionnaires to 334(163 male, 171 female) undergraduate students. Path analysis conducted using structural equation modeling. Path analysis indicated that the overall model fitted the data well. Analysis showed that paranoid tendency and social isolation sequentially mediated relationship between covert narcissism and TKS. The finding suggest that we could focus on covert narcissistic personality, paranoid cognitive process, and behavioral social isolation to understand and intervene TKS.

The focus of this study was on the self-differentiation level of families with an elderly member suffering from dementia. Based on 340 questionnaires collected in Seoul and Gyeonggi, the study intended to explain the adaptation issues of those families. The variables of interest, which might be related to the self-differentiation, were chronic anxiety(i.e. stress), the family function, psychosomatic symptoms and the family's adaptation to care-giving. As a result of analyzing the effects of the variables potentially related to the self-differentiation level of care-giving families, the findings from this study were as follow. With decreasing self-differentiation level of the family caring for an elderly member suffering from dementia, the levels of stress and psychosomatic symptoms were significantly increased, but the family function and the adaptation to care-giving tended to decrease. Conversely, with increasing self-differentiation, the levels of stress and psychosomatic symptoms were significantly decreased, while the family function and adaptation to care-giving were promoted.

현재의 상황인지 컴퓨팅(Context-aware Computing)은 센서로부터 전달받는 상황정보가 완벽하다는 가정을 하고 있으며 따라서, 이에 근거한 상황인지는 불확실성(Uncertainty)을 제대로 다루지 못하고 있는 실정이다. 또한 상황인지 컴퓨팅에서 상황 정보를 표현하는데 주로 사용되고 있는 온톨로지(Ontology) 모델링 역시 현실 세계의 불확실성을 다루기에는 한계가 있다. 본 논문은 선행 연구인 온톨로지 기반의 홍수 상황인지 처리에서 발생할 수 있는 불확실성을 탐지하고 이를 해결하기 위한 방안을 제안한다. 홍수 상황인지를 위한 센서 종류와 수량을 보강하고 기 설계된 온톨로지 모델의 추론 과정 보완을 통하여 홍수 상황인지의 불확실성을 최소화한다. 이는 홍수 상황인지 뿐만 아니라 일반적인 온톨로지 기반의 상황인지 u-서비스에 응용할 수 있다.

The purpose of this study was to explore predictors of positive changes in children with divorced parents and to demonstrate the structural path among the perceived experience of social discrimination, parenting difficulties, parent-child communication, and internet use of children that related to positive changes based on family incomes. The subjects for this study were 1,114 single parents from divorced families sourced from a study on the status of single-parent families in 2015. The results of this study by using the structural equation model of the moderating effect verification with family incomes and multi group analysis are as follows. First, single-parent's perceived experience of social discrimination turned had a significant positive effect on parenting difficulties( =.354) and children's internet use ( =.234). Single-parent's perceived parenting difficulties also had a significant positive effect on children's internet use ( =.440) but a significant negative effect on both parent-child communication( =.192) and positive changes of children( =.218). Interestingly, internet use of children demonstrated a significant negative effect on their positive changes. Second, parent-child communication, parenting difficulties, and children's internet use had a negative mediating effect with the relationship where single-parent's perceived experience of social discrimination had an effect on positive changes of children( =.167). Second, between the family groups based on family incomes, there was no statistically significant difference in the structural relationship. Based on these results, this study presented a practical proposal to help single parents not experience social discrimination and to help decrease the internet use of children to improve positive changes.

Growing boy of studies focus on the letter transposition effect since it gives the information on how letters are coded and what variables are involved in the processes of word recognition. This review investigated various models on letter transposition effect. While most proposed models rely mainly on the bottom-up processes, evidences from various studies suggested the necessity of the top-down variables based on the cognitive processing mechanism. Especially, empirical evidences suggested that Hangul model should include a position specific processing mechanism based on onset, vowel, and coda of the Korean character.
