This study was aimed to find out ancestral environmental protection wisdom in their life style, and to teach environmental education applying its results in primary school. A dissertation survey was conducted to analyze environmental protection eco-wisdom, environmental education about traditional culture, application of indigenous knowledge in ancestral traditional culture for environmental education in the primary school, and Korean traditional culture presented in 5th grade subject courses of the 7th school curricula. In addition, a environmental education program was developed by applying wisdom of traditional life style and the strategy of environmental education utilizing the results from the above data in primary school was explored. It was found that students understand the value of environment education and are more interested in the ancestral life style, environmental protection wisdom from traditional culture. Also, students understand the ancestral thinking in environment, the wisdom of old Korean, and the importance of echo-wisdom related on traditional culture. Based on above results, the suggestions of this study are made as follows. First, by searching for more wisdom from traditional culture vigorously, it is needed that developing more teaching text combined environmental education with traditional culture through other curriculums. In addition, for this kind of teaching being used efficiently in another schools, the place and environmental teaching aid is needed.

To contribute to the globalization of Korean food, a Korean food culture publicity event was conducted at Hayabusa Station, Tottori Province, Japan. This study investigated and analyzed recognition and preferences towards Korean food in participants at the event. The method of information acquisition was also analyzed. Most participants had prior experience eating Korean food. As for information, participants responded that they were affected by public media such as dramas, and the most effective way of getting information was participating in lectures. This study also investigated intake of 20 kinds of Korean food and found highest preferences for bibimbap, kimchi, naengmyeon, and galbigui, in that order. The main motive for participating in the Korean food culture publicity event was a desire to experience a new culture. Further, satisfaction, intention to participate, and intention to recommend Korean food were high. These attitudes had significant effects on the intention to visit Korea. In the future, Korean food culture publicity events held in foreign lands can contribute to Korean tourism.

This study focused on concretely how minority group's attitude accepting han-zu's culture changes. In the past, minority group's culture and han-zu's culture were acculturated spontaneously, not forcibly. But as the people's republic of china was founded and control of chinese government was intensified, control and interference of minority group area became aggressive, and acculturation became compulsory. However, after chinese economic reform, by economic affluence and modernization and urbanization according to economic affluence, acculturation of minority group's culture and han-zu's culture is changing from forced acculturation to spontaneous acculturation. Still there are some areas where mutual friction lasts because of forced acculturation. But except some areas the stream is changing rapidly to spontaneous acculturation. In the text, this study investigated process and present state of acculturation focused on hui-zu that implemented aggressive acceptance of han-zu's culture relatively early. Then this study investigated yi-zu society and cultural change focused on their spontaneous acculturation. In the modern society setting a high value on convenience and personal happiness rather than ideology and value, value of race becomes less attractive to young people of minority group who know modern civilization and convenience of city. In this respect, maybe hui-zu society is future of yi-zu society and minority group society.

Shrimp farming is the most important mariculture industry on the west coast of South Korea. However, it has suffered from mass mortality due to viral disease outbreaks and coastal pollution due to water discharge. This study developed an intensive shrimp culture method for outdoor ponds, without water exchange, which minimizes the chance of viral transmission from the environment, reduces coastal pollution by water discharge and enhances shrimp production. A culture trial was conducted in two high-density polyethylene (HDPE)-lined ponds with a $550\;m^2$ surface area. The ponds were stocked with postlarvae of Litopenaeus vannamei, the major farmed shrimp species in Korea, on July 10, 2007, and cultured for 90 days with no water exchange. The stocking density of the postlarvae (B.W. 0.0015 g) was $272\;ind./m^2$, which is eight times higher than in traditional pond culture in Korea. At harvest, the total production of ponds 1 and 2 was 1,362kg ($2.48\;kg/m^2$) and 1,282 kg ($2.33\;kg/m^2$), respectively. This is 20~22 times higher than the mean farmed shrimp production ($0.112\;kg/m^2$) in Korea and about eight times higher than in traditional ponds with a good harvest. Although there was no water exchange throughout the culture period, the mean concentrations of unionized ammonia and nitrite-nitrogen were as low as 0.038 and 6.0 mg/L, respectively. The feed conversion rate (FCR) was 1.38, which is 20~45% lower than that of traditional pond cultures. The high efficiency of the diet in this study is thought to be due to a well-managed feeding strategy and well-developed bioflocs used as diet additions for the shrimp. The final body weight of the shrimp at harvest was low (12.2~12.5 g), compared with that of traditional pond culture. This may have resulted from the combination of a short culture period, high density of shrimp, and low temperature. This study suggests that a super-intensive shrimp pond culture method using biofloc technology with no water exchange can minimize viral transmission via water exchange, reduce coastal pollution, and enhance shrimp production.

This study was carried out to examine a concentration of steroid hormones and in vitro development of mouse embryos in culture supernatant of bovine granulosa cells (GC). To obtain the culture supernatant, granulosa cells were retrieved from mature follicles (6~15 mm diameter) and immature follicles (2~5 mm diameter) of bovine ovary and were cultured, respectively, in media of Ham's F-10 with 15% FCS for 16 days. Mature and immature granulosa cells formed their monolayers easily and showed similar growth patterns in culturing. There was no morphological difference between mature and immature granulosa cells. High levels of both progesterone and estradiol were detected in the culture supernatant of mature granulosa cells and immature granulsa cells, and the endocrine profiles of the two types of cells were similar. Progesterone secretion of granulosa cells was high in the late stage of culturing and estradiol secretion was high in the early stage of culturing. In vitro development rates of mouse embryos to morula, blastocyst and hatched blastocyst were significantly (p<0.05) higher in culture supernatant of mature granulosa cells (92.7%, 78.1% and 34.5%) and in culture supernatant of immature granulosa cells (96.4%, 78.5% and 26.8%) than in Ham's F-10 (86.7%, 41,7% and 13.3%). However, there was no difference between the culture supernatant of mature granulosa cells and the culture supernatant of immature granulosa cells in the development of embryos.

The study is to examine the mediating effect of psychological empowerment on the causal relationship between high-performance work system and organizational citizenship behavior. This study collected data from public organizations that are responsible for social welfare provision in Daegu, Gyeongsangbuk-Do, and Pusan in South Korea. This study employs confirmatory factor analysis in Amos 21 to find the discriminant validity of all constructs and regression analysis by Baron and Kenny (1986) to test that psychological empowerment is a mediator of the causal relationship between high-performance work system and organizational citizenship behavior. As the result of the analysis, psychological empowerment has a significant mediating effect on the relationship between high-performance work system and organizational citizenship behavior. The study suggests to the managers in social welfare organizations how they need to enhance organizational citizenship behavior through psychological empowerment themselves.

Based upon a questionnaire survey, this research study focuses on the Japanese apparel manufacturers. The aim is to understand the characteristics that make up the marketing strategys of Japanese small to medium sized apparel manufacturers. The authors generate exploratory hypotheses, which are tested via statistical analysis of data obtained from a questionnaire survey. The hypotheses tested include, the relationships between "High Value Added" strategys and factors involved with manufacturing and marketing channels. High Value Added strategys relate to the manufacturers' competitive behaviors that create high and new value for their products. The results indicate that High Value Added strategys have positive relationships for domestic outsources, the number of outsources, use of directly operated shops and the orientation for sales in overseas markets.

The purpose of this research was to develop the education program on traditional living culture for home economics(HE) based on the 2015 revised national curriculum. The existing school curriculum for traditional living culture tends to overly focus on the theories about traditional culture and suffer from absence of continuity in learning activities. It can be argued that HE is an ideal subject for dealing with traditional living culture as it aims to develop students' ability to recreate the traditional culture, meeting present needs and trends. This study, thus, attempted to present the practical ways of improving the quality of education on traditional living culture by developing HE education program for high school students. To fulfill the purpose, this research, as a teaching topic, selected the traditional patterns and the "Obangsaek"(Korean traditional five colors) which can commonly be dealt with in the subjects of traditional Korean food, Korean costume and Korean style house. In particular, the program was developed following the ADDE process. In the stage of analysis, this article analyzed the HE curriculum and making activities included in HE textbooks based on the 2015 revised national curriculum, as well as the needs of teachers and students regarding traditional living culture education. In the stage of design, this study developed the instructional model, selecting class topics, tools and materials. In the stage of development, the programs on traditional living culture including costume, food and house were developed. In the evaluation phase, this research conducted the validity test and received the feedbacks from 12 HE educators in order to complete the programs. This study finally suggested that future studies in this area examine the effect of the presented programs on enhancing the students' perception of traditional culture and the will of developing and succeeding the traditional living culture.
