This research is designed to study the residence environment of the elderly residing in three different types of residence - the local community, silver towns and nursing homes and compare their level of social support and life satisfaction of the residents. The subjects of the study was those aged 65 and older who live single and couple 68 residing in the local community, 32 in silver town and 32 in nursing homes. The result of analysis is as follows; 1) the residence environment is different in the three types of residence in terms of number of children, living with a spouse, subjective economic status, and participation in group activities; 2) as for social support, emotional support is the highest among the elderly residing in the local community and declines among those in silver town and the lowest in nursing homes, which suggests that the local community still maintain the support system for the elderly, however it declines in silver town and drop further in nursing homes. But in terms of instrumental support, there is no meaningful difference in the three types of residence. The result shows that the elderly residing in nursing homes are supported by systematic medical and residence service which make up for instrumental support Similar to those in the local community and silver town; 3) life satisfaction is the highest among those residing in nursing homes, however there was little meaningful difference. The result means quality of living is similar among three different types of residence. What is interesting is those living in nursing homes has similar level of life satisfaction despite their lowest emotional support.

This paper investigates the effects of changes in household structure on service demand. The structure of households in Korea has been quickly changed due to low birth rate and population aging as well as increasing women's participation in the workforce. Their consumption patterns may have been altered by the structural changes. This paper focuses on the additional demand for market services replacing household activities such as household chores and care services. First, using a 3-sector time allocation model, we theoretically analyze the mechanism that marketization of household production can lead to the expansion of service industries. Next, in order to analyze the effects of changes in household structure on consumption demand, we estimate the Engel curves according to the QUAIDS model. For empirical work, the Survey of Household Finances was used. According to the results, structural changes in Korean households, such as an increase in single-person households, a decrease in families with a spouse or children under 6 years old, and an increase in dual-earner households, have caused an increase in medical expenses, education and training costs, and expenses for household services, which are typically substitutes for household production services.

We developed an educational program using soil seed bank for promoting ecological literacy of children. The initial program was based on the modification of scientific methods used by ecologists. A pilot application was conducted to 4th~6th grade students. In that result, the program was most effective to 4th grade students in terms of ecological knowledge and attitude. Observation of plants in outdoor was the most interesting activity and soil seed bank experiment was the most useful activity to the students. The educational period from late March to early November was too long to keep interest for participants. In the final program, we suggested 3 months and 2 weeks education period (from the 4th week of March to the first week of July) and the 4th grade students as a target. The program consisted of 7 activities, which are "Beginning the soil seed banks observation", "Comparing plant community in each soil seed bank", "My friends, sprout", "How do you come here?", "Finding the hided plants in my school garden", "Why did the soil seed banks change?", and "Inquiring about relationship between plants and their environments". These activities include the process of student's participation of sampling and setting soil seed banks around their school, and observing and identifying the seedlings. Through these activities, students can understand the concept of soil seed banks, develop their ecological knowledge, eco-centric attitude, and ecological sensibility and inquire about the relationship between vegetation from soil seed banks and their environments.

The study aims to comprehend the effect of the wetland ecology education on the elementary school students' changes of recognition about wetland through the wetland ecology map program. In this study, the literary research, the experimental research and the survey methods were operated. Through the literary research, the environmental factors were extracted, and the writing item of ecology map was reconstructed based on the literary research, so the experimental research was operated with the wetland ecology map program. Through four areas of test items such as the information and knowledge, values and attitudes, development and conservation, behavior and participation, and the analysis of children's study results, the effect of the wetland ecology map program on changes of recognition about wetland was verified quantitatively and qualitatively. Wetland ecology map program would be able to be an educational approach which can achieve the 'personalization of environment' setting up predictable environmental improvement goals and satisfying the needs of spatial information of the appropriate regions from the holistic perspective that students themselves plan and participate beyond a one-time experience program. Production of ecological map through continuous monitoring is expected to improve the possibility of subjective environmental actions by operating self-directed learning. Based on the conclusion of this study, we would suggest the following. For wetland ecology map program to be supplemented and utilized, the basic education of wetland should be organized in regular school curriculum, ecology map program including various teaching learning methods be prepared actively, and in future studies, studies of ecosystem-wide wetland ecology map program including animals like birds and fish are necessary.

As Korea has undergone rapid modernization, urbanization and industrialization, women's social participation has increased. Accordingly, child care facilities have shown continuous growth in numbers. However, according to research, child care facilities in Korea lag behind those in other nations in terms of quality. Given that, it seem urgent to enhance the quality of child care facilities and improve their indoor environment. Above all, overall atmosphere, colors and finishing materials are connected directly with educational effects as well as feelings and health of facility users. This study assesses the current state of child care facilities and preferences by focusing primarily on interior atmosphere, materials and colors. For This Study, 7 facilities were surveyed, and 46 subjects were participated for this study. The findings suggest that "pretty" style is preferred to "natural" style. As regards flooring material, wood floor is preferred. It is recommended to lay pastel colored carpet or PVC flooring material to the wood floor. As for wall, it is desirable to divide the wall spaces by adding wood and painting to simple wallpapers. In case of the ceiling noise absorptive material is recommended to use instead of wallpapers. For the doors, it is desirable to use contrasting materials and colors given accessibility for children. In the meantime, rather than strong primary colors, soft color or pastel colors are desirable for furniture. This study has limitations because of insufficiency of case study samples. However, it is significant in that the study results may be used as primary source of information to improve the environment of child care facilities.

This study is a second analysis of the 7th Korean Longitudinal Survey of Women and Families. And, it is a descriptive survey research for comparing parental and health characteristics of 2 groups of workers and non-workers. For this, it has used crossover analysis and logistic regression analysis with the subjects of mothers of preschoolers - of 697 females in total, aged between 19 and 64. Based on the result of the logistic regression analysis, we have discovered a few factors inducing the females to participate in more economic activities. The factors are as follows : baby sitters available, the more number of child care centers, the more helps of baby sitting from the females' parents and in-law parents and physical activities less than 3 times a week. In contrast, however, the more preschoolers they have, the less likely they are to take an active part in the economy. Against the backdrop, the government should develop social service systems to encourage various child care services and to foster 'child raising mothers-friendly' environments not only in families but in workplaces. All this is to improve the health characteristics of preschoolers' mothers in a more healthy way' and to strike a balance between work and family.

Endoplasmic reticulum (ER) stress is mediated by disturbance of $Ca^{2+}$ homeostasis. The store-operated calcium (SOC) channel is the primary $Ca^{2+}$ channel in non-excitable cells, but its participation in agent-induced ER stress is not clear. In this study, the effects of tunicamycin on $Ca^{2+}$ influx in human umbilical vein endothelial cells (HUVECs) were observed with the fluorescent probe Fluo-4 AM. The effect of tunicamycin on the expression of the unfolded protein response (UPR)-related proteins BiP and CHOP was assayed by western blotting with or without inhibition of Orai1. Tunicamycin induced endothelial dysfunction by activating ER stress. Orai1 expression and the influx of extracellular $Ca^{2+}$ in HUVECs were both upregulated during ER stress. The SOC channel inhibitor SKF96365 reversed tunicamycin-induced endothelial cell dysfunction by inhibiting ER stress. Regulation of tunicamycin-induced ER stress by Orai1 indicates that modification of Orai1 activity may have therapeutic value for conditions with ER stress-induced endothelial dysfunction.

Objectives: While employed mothers' use of maternity and parental leave has increased, the contexts that facilitate or hinder mothers' leave policy use have been under examined. The purpose of this study was to explore mothers' experiences of using maternity and parental leave. Method: Twenty-two mothers with young child under age three participated in this study. Results: All 22 mothers used maternity leave and 12 mothers used parental leave. Three main themes were identified: different experiences of maternity leave, experiences of parental leave, and skepticism about the leave policy but with some hope that it will improve. Regarding the mothers' experiences of maternity leave, the mothers thought that maternity leave was easily accessible but some mothers still felt guilty for using maternity leave. They also prepared for their work gap before the leave to avoid harming their colleagues. Accessibility to parental leave varied according to the characteristics of the organizations (i.e., family-friendly organization culture, supportive supervisor) and family contexts (i.e., availability of child care from family members, financial issues). The mothers perceived that while parental leave helps working mothers coordinate their family and work life, it is not as accessible as maternity leave in Korea. They suggested extending the maternity leave duration and improving accessibility to parental leave. Conclusions: These findings suggest that policy support is warranted to help employed mothers with young children remain in the workforce. This study also has implications for supporting employed mothers' work and family life.

The purpose of the study is to visualize the concept of water circulation in elementary school students through science behavioral system. Elementary school students found it difficult to understand concepts related to the water cycle. Most of the elementary school children think it rains because the clouds are heavier. It is most difficult to explain invisible concepts to elementary school children. Also, experiments in current textbooks are likely to disrupt scientific concepts. Accordingly, conventional water cycle, dew, fog, and cloud experiments were integrated into one system. The researchers then developed a device that allowed students to see the water's circulation at a glance. It is intended to enable integrated thinking on evaporation, condensation and precipitation. In addition, a instruction program to guide students using the system has been developed to demonstrate its effectiveness. Employing a quasi-experimental design, the participants were measured on their concepts of evaporation, condensation, and water circulation before and after participation. The findings indicated that the experiment is more effective in changing the concepts of evaporation, condensation, and water circulation than in previous experiments. Also, the optimal conditions for making use of the device were found, and there were no various experimental parameters, such as condensation.

Focusing on the role of the science museum as an institution to improve the scientific literacy of the public, this study investigated public perception and behavior about science museum to know how much science museums affect the public by using social media big data analysis. For this purpose, we extracted texts containing 'science museum' in Naver blogs and Twitter, analyzed them by using network, frequency, co-ocurrence, and semantics analysis and compared them with the results in English speaking countries. As a result, blogs were mainly concerned with science museum among parents who have young children, while in Twitter posts from many students who visited as a group appeared. Therefore, the Korean public used science museum mainly as a space for children's experience, and in this case, programs and exhibitions of science museums are perceived positively. On the other hand, students who visited as a group showed some negative emotions. The result of comparison with the cases of foreign countries in terms of the function of the third generation science museum such as communications with the science museum and the public and the participation of the public in science, the Korean public hardly mentioned the scientific contents, words related to communications such as 'argue', and curators or staff after visiting the science museum. In contrast to many verbs related to meaningful activities such as 'learn', 'participate', 'listen', 'read', 'ask', 'think' appeared in English, only a small number of verbs include 'ask' and 'thin' appeared in Korean. Therefore, science museum need to improve impression, communicating with public, and involving activity with impact and variety after visit.
