This study set out to develop and evaluate an educational program for the Clothing Life of Home Economics through the theme-based integrated approach develop integrated thinking abilities for solving everyday problems. For those purposes, it selected a couple of themes in the area of Clothing Life toward which the theme-based integrated approach could be develop and evaluate an educational program. The developed program was applied and assessed in total 28 hours of field lessons given to eighth graders attending B Middle School in Busan Metropolitan City. The analysis stage involved an exploration into programs related to an integrated approach to other subjects; the design stage identification of program types; and the development stage theme selection according to the selection criteria. The previous studies were analyzed along with the Technology and Home Economics textbooks to select a theme. two themes "Clothing Management" and "Fabrics(Materials)" were selected after discussing with the students on the Messenger and with a group of experts. Then content was organized and composed around the themes by discussing connections with other subjects. There were three evaluation; one by experts, another through preliminary lessons, and the other through field lessons. Following the research procedure, a theme-based integrated program was developed for the two selected themes. It contained total 49 and 32 learning materials for "Clothing Management" and "Fabrics(Materials)," respectively. Those learning materials were comprised of experiments and practices according to the nature of the themes. Each program consisted of the goals, learning content, content organization chart, learning activities, and evaluation; learning activities experiences, practice and experiment activities, self-directed activities and problem-solving processes; and evaluations self-evaluation, teacher evaluation, peer evaluation, portfolio, and experiment reports. The program was assessed three times. The first and second evaluation results found that the program was well compatible with the current needs, was properly organized to give lessons through integration with other subjects, and continuously maintained the students' interest. They, however, requested that there should be detailed explanations about each part of the program content. In the third evaluation done by the students during field lessons, 60% of them said that the program was fun and its content was easy to understand, that they realized a theme could be connected to several other subjects, and that the program could be applied to actual life. The educational program through the theme-based integrated approach is significant in that it is an educational program for the area of Clothing Life and tries an integrated approach. It helped the students not only gather knowledge in an integrated manner, but put it to practical uses to solve various problems they faced in actual life by creatively changing integrated knowledge. The study will be hopefully used by many teachers so that the students solve problems based on the ability of integrating various knowledges organically.

The purpose of this study is to analyze the effect of different working days of married working men and women on their time use on the weekend. The data collected by The National Statistical Office in 1999 was used. Among the total sample of 17,000 families, 7580 samples who are married, employed, and more than 20 yews old are selected for the analysis. This study has resulted in two major findings. (1)the working days affect on the time use on the weekend. The pattern is somewhat different by sex. The women spend more time in leisure and houseworks on the weekend as the working days decrease. However, the men do not spend more time on doing houseworks as the working days decrease. The time spent on leisure and physiologic time is increased both men and women as the change of workweek from the biweekly five-day to the weekly five-day: (2)if the five-day workweek and more flexible hours are introduced, they will contribute to Improve the quality of life of workers. This fact shows positive view at the last stage of legislation of the five-day workweek .

End-uses of household water have been influenced by a housing type, life style and housing area which are considered as internal factors. Also, there are external factors such as water rate, weather and water supply facilities. Analysis of influential factors on water consumption in households would give an explanation on the cause of changing trends and would help predicting the water demand of end-use in household. In this paper, we used real data to predict toilet and laundry water-uses and utilized the linear regression model with autoregressive errors. The results showed that the monthly autoregressive error models explained about 71% for describing the water demand of end-use in toilet and laundry water-uses.

The purpose of this study was to investigate middle school Home Economics(HE) teachers' perspective on HE curriculum, their Housing Education Value in Home Economics, and then find out correlations between them. Questionnaire was administered to HE teachers who had experienced teaching Housing content over the whole country through e-mail or face-to-face meeting. 207 data collected from the responses were finally analyzed statistically with mean, standard deviation, percentage, T-test, one-way ANOVA, post verification(Scheffe) and Pearson correlation by using SPSS/WIN(ver. 10.0) program. The results of the study were as follows: First, about Home Economics teachers' perspective on HE curriculum, the existential perspective was the highest, followed by the structural perspective and the traditional perspective. Second, about their perspectives on Housing Education Value, generally the most important thing they value was an aspect of ecology, followed by an aspect of economics, an aspect of Socio-Psychology, an aspect of space planning, an aspect of local environment, an aspect of career education, an aspect of culture, an aspect of housing management and an aspect of housing policy. Third, about the relation between their perspectives on curriculum and Housing Education Value, among 9 kinds of Housing Education Value, the traditional perspective was low associated with only housing management value including to Housing Education Value. However, the existential perspective and the structural perspective tended to be moderately or low associated with most of the values including to Housing Education Value.

In addressing the prominent issues of climate change, resource scarcity, and environmental pollution associated with household waste, extensive research has been conducted on intelligent waste classification methods. These efforts range from traditional classification algorithms to machine learning and neural networks. However, challenges persist in effectively classifying waste in diverse environments and conditions due to insufficient datasets, increased complexity in neural network architectures, and performance limitations for real-world applications. Therefore, this paper proposes i-YOLOX as a solution for rapid classification and improved accuracy. The proposed model is evaluated based on network parameters, detection speed, and accuracy. To achieve this, a dataset comprising 10,000 samples of household waste, spanning 17 waste categories, is created. The i-YOLOX architecture is constructed by introducing the Involution channel convolution operator and the Convolution Branch Attention Module (CBAM) into the YOLOX structure. A comparative analysis is conducted with the performance of the existing YOLO architecture. Experimental results demonstrate that i-YOLOX enhances the detection speed and accuracy of waste objects in complex scenes compared to conventional neural networks. This confirms the effectiveness of the proposed i-YOLOX architecture in the detection and classification of multiple household waste objects.

The residential energy consumption is intimately related with lifestyle of consumers. Therefore, this research suggests the mechanism for the effects of consumer lifestyle on consumer behavior. Specifically, the mediators are imposed of cost perception, propensity for environmental protection and energy conservation-conscious. Also, the lifestyle is composed of the over-consumption, life-centric, life-satisfaction, conservation- conscious and conservation-active type. In results, there are positive relationship between the life-satisfaction, conservation-conscious and conservation-active lifestyle and the propensity for environmental protection, cost perception. Both the cost perception and the propensity for environmental protection are positively related with the conservation- conscious. And positive relationship are appeared between the conservation-conscious and the energy conservation behavior.

The purpose of this study is to look at families as presented on the technology-home economics subject of middle school. To do this, I analyzed the 2007 revised curriculum of the technology-home economics subject, 'Changing Families,' in 11 technology-home economics textbooks (8th grade). The findings are as follows. First, family-related chapters are expanded compared with the previous curriculum in the 2007 revised curriculum. In addition, the new version emphasizes understanding and acceptance of change in families to improve the family life of adolescents. Second, in the 11 types of technology-home economics textbooks, the focusing was on the meaning of the family, the family structure, the function of the family, family roles and family values. There were also no major differences in the aspect of development. Third, in the technology-home economics textbooks, the family was defined as the 'basic group of society', 'a group composed by blood relationships, marriage and adoption', 'an affective group' and 'cohabiting group'. At the same time, there were many cases in which the description of the family was overly romanticized. Such a description of the family does not match the individual family experience of an adolescent. Fourth, all of textbooks dealt with the diversity of the family structure, such as single-parent families, remarriages families, and multi-cultural families. However, the structural characteristics and problems with these types of families are excessively emphasized, which can result in students having stereotypical images of specific family types. Fifth, the explanation of the function of the family was similar among textbooks. The importance of intergenerational cooperation and gender equality was also emphasized. However, such a concept is not considered as proper in a modern society. Thus, the description of a family based on the nuclear family should be sublated. In addition, the explanation of families overall should be developed in such a way that adolescents can interpret their own family experience rather than as an enlightening declaration of the family which disregards the dynamic relationships individual families actually experience.

The purpose of this study is to investigate time use of married female clerical workers and their husbands. Data for 143 couples were gathered from using structured questioinaire and time dairy. The analysis of time use data was carried out two approaches. They are the amount of time spent and the distribution of time for dailly activities. And also the couples' perceptions how restricted their long time labor to their family life was analyzed. The results were shown as follows: (1) Married female clerical workers and their husbands have long labor time and their physiological and leisure time is too short. This means the patterns of their time use are very unbalanced type. (2) Wives worked longer than husbands on total labor with a large sexual difference in household works.(3) Couples perceived that wives' work more negative affection on their family life than husbands' work.

This study is (1) to analyze urban employed husbands' time use applying a framework which classifies a day into public time familial time and individual time in order to demonstrate its disproportion in terms of their and their families' welfare(2) and to identify the related factors to their time use. Data for 280 husbands were gathered through structured questionnaire and time diary. Major findings are as follows; (1) Husband's time allocation is usually concentrated on their individual and public time while they spend relatively very short familial time. (2) Types of occupation age and wives' employment status are all related with husbands; time use but their sex-role attitude shows no significant relation.
