This study was carried out to compare the meal management attitudes among the mothers(41 years of age) who had middle school students between in industrial complex and in non-industrial complex. The subjects of each group were composed of 192 mothers Living in Ansan city in Korea, and this study was performed by self-administered questionnaire. The results of the present study were as follows: (1) Monthly family income and education level of parents were lower in industrial complex-family(ICF) than in non-industrial complex-family (NICF). The mean age of mothers and family size were similar in two groups, but the frequency of mothers employed was higher in ICF than in NICF Most mothers in ICF worked as a manual- or skilled-laborer. (2) The mothers in ICF tended to have less positive attitude in sewing balanced meals to their families than those in NICF. The score of nutritional knowledge was lower in mothers in ICF than those in NICF. (3) The percentage of expense for purchasing staple foods to total expense of foods tended to be higher in ICF than in NICF. Engel's coefficient was higher, and the frequency and expense for eating out was lower in ICF than in NICF (4) The mothers in ICF did not try to use their time and energy efficiently for meal management. (5) The mothers in ICF were less active in sewing the pleasurable meals including the provision of various cooking methods, flavors, and temperatures, to their families, than those in NICF. Above findings show that family environment such as industrial complex-families and non-industrial complex-families influences the meal management attitudes of mothers. The mothers in ICF had a less positive altitudes for scientific meal managements than those in NICF even though they had the limited resources including money, time and energy for meal management because most mothers in ICF had a job that were paid low salary and finished irregularly or late. Therefore, these results underscore the need to provide the sound nutritional education for the mothers in ICF with respect to reasonable meal management for 'optimal nutrition of family'. In addition, the government should try to make the various welfare policies to improve nutritional status of low income famines including the poor industrial complex-families.

This study was carried out to compare the dietary behaviors and nutrient intakes among the students(13 years of age) of middle schools between in industrial complex and in non-industrial complex. The subjects of each group were composed of 192 male and female teenagers living in Ansan city in Korea, and this study was performed by questionnaire and dietary survey. As a result, mothers' education level and monthly family income were lower in industrial complex-families(ICF) than those in non-industrial complex-families(NICF). The subjects in ICF took dinner more irregularly than did those in NICF. The subjects in ICF skipped the meals often as there was no person preparing meals'. The subjects in ICF tended to take ra-myun, cookie or bread more often as a lunch, and they considered size and price of snack more imporandy when they chose snack than those in NICF. And the subjects in ICF had lower degree of flood habits and satisfaction on their meals than those in NICF. The daily intakes of calorie, vitamin B$_2$, calcium and iron of subjects of two groups were lower than the Korean RDA, and these intakes were lower in ICF than in NICF. These findings show that dietary behaviors and nutrient intakes were poor among the students of middle schools in ICF, in part it seems to be related to the fact that the group of ICF has low family income and mothers of ICF have the jobs that are finished late or irregularly. Therefore, these results underscore the need to provide the nutritional education for the students of middle schools and their mothers in ICF with respect to the importance of optimal nutrition through sound dietary behaviors during the adolescence.

The present study examines the connections and effects of these historical events on South Korea's education system. The research seeks to illuminate private education's complex history and the complex factors that have shaped it by examining these historical trajectories. After the Korean War in the mid-20th century, South Korea went from agrarian to industrial, which shaped private education. Unparalleled economic growth in the 1960s and 1980s altered schooling. South Korea quickly became an industrial powerhouse, and education became crucial for families seeking socioeconomic advancement. The growing middle class, believing education was the key to prosperity, demanded more extra education. South Korean private education's fourth major event occurred during the socioeconomic upheavals of the 1960s-1980s. Prior studies explain how the fast transition from agrarian to industrial society made schooling essential for families seeking upward mobility. Due to the demand for extra education, private tutoring and specialist hagwons flourished. In summary, this study insists that the effects of historical events on South Korean private education demonstrate the interconnection of cultural, economic, and sociological aspects. Educational practitioners must comprehend the historical backdrop, recognize the lasting impact of past events, and use literature-based tools to navigate this complex landscape.

The purpose of this study was to explore sexual behaviors among adolescents in multicultural families in Korea. The data were obtained from the 15th Korea Youth Risk Behavior Survey 2019. Complex-sample descriptive statistics and the chi-square test were used for data analysis in SPSS 25. Among adolescents in multicultural families, 8.2% reported having sexual experience. Condoms were the most commonly used contraceptive method, and most adolescents received sex education at school. Their likelihood of sexual experience differed according to grade, academic achievement, economic status, residential area, perceived stress, and drinking and smoking experience (p<.001). The results of this study suggest that sex education should be conducted with appropriate consideration of the important factors associated with adolescents in multicultural families.

Increasing product variety based on product family and product platform provides a company with a competitive advantage over its competitors. As products become more complex, short-life cycled and customized, the design efforts require more knowledge-intensive, collaborative and coordinating efforts for information sharing. By sharing knowledge, information, component and process across different families of products, the product realization process will be more efficient, cost-effective and quick-responsive. Formal Concept Analysis (FCA) is used for analyzing data and forming semantic structures that are formal abstractions of concepts of human thoughts. A Web Ontology Language (OWL) is designed for applications that need to process the content of information instead of simply presenting information to humans. OWL also captures the evolution of different components of the product family. The purpose of this paper is to develop product variety modeling to increase the usefulness of common platform. In constructing and analyzing product ontology, FCA is adopted for conceptual knowledge processing. For the selected product family, product variety Ontology is constructed and implemented using prot$\'{e}$g$\'{e}$-2000.

Equipment designer should consider how many people and what range of percentiles will be used as design criteria. The usual practice is to select some large range of the accommodation, such as 5th-95th percentiles. There is difficulty in defining 95% accommodation of population in complex design problems which involve several body dimensions. This paper develops the methods of constructing family of manikins which are validated for population accommodation. They are analyzed by the interactions or relationships between body dimensions. Proposed manikin family represents multivariate body dimensions. Moreover, nine manikin families are determined for representative Korean of 30-50 aged by proposed manikin family. Their 2-D CAD modelings are developed for bio-mechanical and ergonomic applications.

Nowadays, air pollution by increasing consumption of fossil fuels resulting from rapidly growing population and industrialization has caused the adverse effects on terrestrial ecosystems and become one of the most serious problems causing environmental discriptions. Air pollution such as $SO_2, HF, NO_X,$ fly ash, ozone and PAN might influence plant growth, reproduction, nutrient cycling, photosynthesis and predisposition to entomological and pathological stresses on plants. Furthermore, accumulation of those toxic substances in forests might cause subtle or serious changes in the structure and function of forest ecosystems. Since 1970s, a number of large industrial complexes had been constructed as a part of industrialization plan in Korea. Accordingly, the forest exosystems around them has been under chronic influences of air pollution and effects of air pollution on plants became a matter of concern. In Yocheon Industrial Complex which consisted of lots of petrochemical plants and a phosphatic fertilizer manufacturing plant, forests has been exposed to chronic air pollution, mainly HF and $SO_2$ gas, Various reports were available to investigate the potential effects of air pollution on crops and forest trees in Yocheon. Kim and Kim surveyed vegetation by naked eye method and reported 71 families, 150 genera and 158 species were growing within a 2 km from air pollution sources in 1981. Needle injuries on Pinus spp. in the polluted area water reported by Kim, et al. and Kim, et al. Kim, et al. investigated the primary production of Pinus thunbergii forests in the polluted area and verified that growth inhibition of Pinus thunbergii was attributable to air pollution. Thus, previous reports suggested that forest ecosystems around Yocheon Industrial Complex were influenced adversely by air pollution. The objective of this study was to investigate the subtle ecological changes in forest community exposed to chronic air pollution in Yocheon.

As the proportion of women's participation in economic activities is rising, the increase of husband and wife both working and nuclear families makes children up-bringing a social problem. But many families have difficulties by the shortage of day nurseries which can solve it. As we can see in the research, the most urgent problem is the extension of nurseries in quantity. In Taegu, since it became a wide-area city, there are 473 nurseries. But in the respect of distribution, only less than 10% of Dongs have more than 7 nurseries and more than 90% of Dongs have less than 7 nurseries. Consequently nurseries are extremely insufficient. Moreover 29 Dongs don't have any nurseries at all and they take 18.6% of Dongs. The second problem is the unbalanced distribution of nurseries. West and north ward which are industrial complex and swarmed with low-income families, and Tal-sung county which is recently included in the wide-area city keenly need the establishment of nurseries. Besides, Bi-san 1 Dong and Non-gong which have only $1{\sim}2$ nurseries though they have high proportion of children and women who can be pregnant are also the areas which take precedence of nursery establishment. The third problem is that government support must be increased in the areas which have many small, petty and profit-making private nurseries so that good quality teachers can make breeding activities in nice facilities and environment. In materials which are obtained by the interviews with publich servants in charge of family welfare in some ward offices. Young and unexperienced persons who aquired certificate of qualification take day-nursery permits and run nurseries only a few months. and if the profits are insufficient, they sell the nurseries for premiums to third persons who are not qualified. Then the third managers only think of profits without thought of good quality childcare. As the result, the nurseries become asylums not nurseries. That is why the conditions of nursery establishment must be restricted to suitable scale and experienced persons. The fourth problem is that the nurseries in work places are extremely insufficient. The women who have jobs have many things to do before they go to work such as preparing meals and leaving children in the care of someone. Hence the childcare problem of working women must be solved. In nuclear families, childcare is the most serious problem for working women. The fifth one is the reduction of childcare expenses. Women must sacrifice themselves a lot to make social activities. To say nothing of physical and mental burden, they have to spend much of their salaries on childcare. And yet they don't take the benefit of good quality childcare. For the participation of women in public affairs, society must support the childcare problem to have then be devoted to their jobs without worries about their children. Therefore Taegu wide-area city must select west, north ward which are industrial complex and the low-income swarmed area before everything and establish many national, public and corporate nurseries which cost less expenses.
