This study reviewed critically the music regulations of broadcasting advertising and analyzed the post reviews of Korea Communications Standards Commission(KCSC) to find their problems and suggest alternatives for their improvements. As general core regulations, lyrics changes of children's song is banned except in non-commercial public advertising and lyrics changes to folk songs are permitted unless it includes the product related expressions, such as brand name; both of their arrangements are permitted. According to the items, the lyrics of the CM song of drug advertising should not include its brand name; alcoholic beverage advertising is banned if the lyrics of the CM song include product-related brand name or an expression encouraging drinking. The rationales of these regulations of restrictions or prohibitions of music in broadcasting advertising are unclear and are insufficient. Therefore, it will be necessary to improve them based on the evidence or knowledge by more valid research in the future.

This study was carried out to investigate the introduced household machines during the industrial period and the effect of them on housework. This study utilized the methods of historical research. The major findings of this research were as follows; (1) The method and process of housework was altered dramatically by the introduction and spread of household machines during the industrial period. (2) Household machines made housework more easy and timesaving but they had little effect on the houseworker's total burdens because of the rising standares, the addition of new housework and the return of housework to the home which had bean substituted by the market services.

We attempted an experimental study of lost-wax casting to reconstruct the Gilt-bronze pensive Bodhisattva; The main object we aimed to reconstruct was the Korean national treasure No.83, Gilt-bronze pensive Bodhisattva(Maitreya); thus, we scientifically analyzed and measured the alloy ratio and casting method. Initially, the alloy ratio we used during the preliminary experiment was Cu:Sn:Pb = 95.5:4.0:0.5; we then increased tin and lead by 2.5% to consider vaporization during the main experiment. After applying lost-wax casting, we realized that 30% rosin contributed to proper hardness after the wax hardness experiment. The microstructure revealed normal casting character(α-Cu, δ), and the results of the chemical analysis are identical to those of previous studies. The analysis of the mold suggests the presence of quartz powder for structural stability and fire-resistance along with other organic materials whose contribution is still unknown. We expect that our research will serve to provide basic data for advanced studies in the future.

This paper analyzes the factors influencing the childbirth intention of married women with the goal of analyzing whether times of spouses' housework, marital satisfaction, values of children and traditional gender role, and social services related to the reduction of low fertility contribute to women's intention to give birth. The respondents of the research were 1,000 married women, and the research was conducted with 482 women of childbirth intention. The findings are as follows. Age of sociodemographic factors has an influence on the childbirth intention. Related to family's character, factors influencing childbirth intention are number of children, times of spouses' housework, and marital satisfaction. In addition, emotional and instrumental values of children, number of recognized public services for reduction of low fertility. In other words, the more women share housework with spouses and satisfy their marital life, the more childbirth intention of women is increased. In order to improve childbirth intention, changes of perception of gender role and sharing housework, reinforcement of social system for work and family compatibility that convert changes of perception into action, advanced marital relationship programs, extensive support for subfertility and a huge build-up of social services related to reduction of low fertility need to be provided.

The purpose of this study is to analyze the moderating effect of care service satisfaction, housework sharing, gender equality consciousness, and gender role attitude on the relationship between work family balance and the psychological well-being of working mothers. This study was conducted from March 20, 2013 to March 26, 2019, with a total of 163 questionnaires for working moms having elementary school children. The results demonstrating the positive effect of care service satisfaction provide policy implications for extending the care service system. Notably, it was confirmed that psychological well-being increased in cases of work-family conflict as housework sharing, egalitarian sex role attitude, and gender equality consciousness increased. Therefore, subsequent study will be necessary to discuss further about sharing the spouse 's housework and raising the gender equality consciousness.

산소소비량은 어류 양식 시설의 수용 능력을 결정하거나 활어를 수송할 경우에 특히 중요한 인자로 작용한다. 이를 위해 활어 수송 시에는 산소소비를 낮추려고 마취제, 이산화탄소, 전기자극 등의 방법으로 일시적으로 가사 또는 가면 상태로 하여 운송하기도 하지만, 대개는 어류의 산소소비량과 대사량을 최소화하도록 수온을 낮추어 운송한다. (중략)

The unsaturated polyester(UP) and epoxy resin have a superior material properties and a chemical resistance using sewerage pipes rehabilitation. However, UP and epoxy have not a low temperatures harding, the requirement $8{\sim}11$ hours long times harding and heating system used by reinforcement liner. This study is to evaluate the effects of low temperature harding properties methyl methacrylate(MMA) monomer using expanded polystyrene(EPS) and UP in addition of initiator and promoters. From the test result, viscosity tends to increase with increasing EPS and UP contents. However, harding time change of the MMA resins which it follows in addition of the initiator and promoter.

To achieve this objective, practical problem-teaching lesson plans and instructor-led teaching and learning plans were developed and integrated into the Technology Home Economics, and Human Development curricula at both academic and vocational high schools. The impact of these plans was examined, as were connections between the teaching methods and types of schools. As part of this study, a survey was conducted on 1,263 students in 46 classes at 6 randomly selected high schools: 4 academic and 2 vocational. A total of 9 teachers conducted classes for both experimental and comparative groups between October 2009 and November 2010. Pre- and post-tests were used to study the impact of the lessons on the experimental and comparative groups. In terms of data analysis and statistics processing, this study implemented mean and standard deviations, t-test, and analysis of covariance using the SPSS 12.0 program. The results of this study are as follows. The practical problem-teaching lessons produced more positive results in the students than the instructor-led lessons, in terms of their image of the elderly, their level of knowledge about them, their understanding of their need for welfare services, and preparation for Successful aging. When comparing the results by type of school, the experimental groups at academic high schools appeared to have a more positive image and better understanding of the elderly and their need for welfare services, and were better prepared for Successful aging than during their previous lessons. They also showed an increase in independence from their children in aging. As for the comparative groups, students at academic high schools showed an increase in preparation for Successful aging compared to the previous lessons. Finally, as for future research on preparation for aging in high schools, more schools should include this subject in their regular curriculum for Technology Home Economics, Human Development and Home Economics in order to generalize the results, and they need to evaluate the content. Additionally, this study suggests that new high school curricula should include lessons on preparation for aging so that students can deal successfully with our aging society.

This research conducts a comparative analysis of the perceived importance of advancing zero energy building certification from the viewpoints of two major stakeholders - designers and building energy assessors. Both groups prioritized the importance of policy, technology, education, incentives, and promotion respectively. For designers, enhancing energy efficiency standards, developing a skilled energy workforce, and implementing an office registration system emerged as critical factors in invigorating the certification process. The findings suggest potential avenues for the government to formulate realistic strategies for boosting the certification activity.
