This study aimed at developing an educational program for South Korean adolescents on North Korean family living culture so that the students become familiar with the values and everyday lifestyles of North Korea. Understanding of North Korean culture is considered important as a foundation for social integration in prospect of future reunification. The contents of the program were developed based on the analysis of North Korean defectors' interviews and review of the literature and media reports on North Korean family culture. The program consists of 12 units of 40-minute sessions with the following topics: economy and consumption, leisure activities, family relationships, dating and spouse choices, fashion changes, clothing acquisition and care, food choices and local diets, dietary problems, housing, and neighborhood. The program was implemented between December 21 and 30, 2015 in a middle school located in Seoul. This program is expected to be useful in preparing the students as future leaders to create harmonious family living culture in the reunified Korea.

Iris dichotoma Pall. found on Daechung Island in Korea has been designated as an endangered species. To aid in conservation efforts of this species, this study investigated its germination characteristics and seed dormancy type. Four sets of seeds were incubated at different temperatures (4/1℃, 15/6℃, 20/10℃, and 25/15℃). One set of seeds was cold stratified (4 weeks at 4/1℃). The final germination rate and mean germination time showed that the optimal germination temperature was 25/15℃. Final germination rates were ~70%, showing no significant difference among temperature treatments. However, mean germination time were significantly different among all temperature treatments except for 4/1℃. Mean germination time for seeds with temperature treatments of 15/6℃, 20/10℃, and 25/15℃ were 3.2, 2.1, and 1.5 weeks, respectively. At 25/15℃, the mean germination time was half of that at 15/6℃. Seeds of I. dichotoma had fully developed embryos at the time of dispersal. No additional growth of the embryo was observed. Cold stratification did not affect the final germination rate or the mean germination time. This study shows that seeds of I. dichotoma have no physiological or morphological dormancy, unlike other members of the Iris genus known to have seed dormancy that needs a relatively high incubation temperature (≥25/15℃) for mass propagation to occur. These results will be useful for understanding ecophysiological mechanisms related to the species' habitat. They are also useful for mass propagation of I. dichotoma for the purpose of conserving this endangered species.

This study aims to propose biotope field datasheet and biotope type classification based on habitat-based by analyzing the German biotope system. The German system began in 1976 and has established a habitat-based national biotope classification system. On the other hand, Korea institutionalized in 2018 to build a classification system based on land use and land cover, which is a classification system that does not fully reflect ecosystem in Korea. Germany operates 44 biotope classification systems and 40 biotope field datasheet. Korea uses a single biotope field datasheet regardless of the biotope type. This classification system may not reflect the characteristics of Korea's biotope ecological habitat. The biotope classification system of Korea was proposed by dividing it into five categories: mountain ecology, freshwater ecology, land ecology, coastal ecology, and development area to reflect ecosystem habitat. The biotope type was designed as a system of large-classification-middle-small classification and subdivided into medium-classification and subdivided in each biotope system. The major classifications were classified into 44 categories according to the mountainous biotope(11), freshwater biotope(8), terrestrial biotope (12), coastal biotope(6), and development biotope(7). Unlike Germany, Korea's biotope field datasheet was proposed in five ways according to the classification of major ecosystem types. The results of this study are expected to contribute to the policy suggestion and the utilization of ecosystem conservation because the biotope classification system is classified to reflect the characteristics of ecosystem habitats.

As Korea is moving toward multicultural society, the number of Muslim, whose religion has a great influence on diet-related behaviors, is increasing in Korea. Since the number of immigrants from Indonesia ranks within top ten in Korea and Indonesia is one of the most representative Islamic countries in Asia, understanding the diet-related behaviors and food preferences of Indonesians is needed. This study was conducted to investigate diet-related behaviors, factors affecting the diet-related perceptions, and food preferences of the Indonesians. The subjects included 500 Indonesians dwelling in Jakarta, Indonesia. About ninety % of the subjects in this study were Muslims. They did not eat pork and dog meat for religious reason and they practiced fasting during Ramadan period. Indonesians avoided pineapple, durian, and hot foods during pregnancy and usually ate vegetables and fruits after birth, which seemed to be due to sociocultural influence. Among the subjects, 21.5% were obese and major health problems reported were hypertension and hyperlipidemia. Their preference for fried food items might have contributed to health problems. Subjects had meals mostly at home (2.3 times/day) and dined out occasionally (1.2 times/week) at Indonesian restaurants (56.6%) or family restaurants (21.0%). In conclusion, Indonesians had home-based and native food-oriented dietary life with strong religious and sociocultural influence on food choices. Further research on specific nutrient intake analysis is needed to better understand and to improve dietary life of Indonesians in Korea.

To restore the connectivity of fragmented habitats, 415 wildlife crossings have been built between 1998 and 2014 in South Korea. However, their effect on wildlife conservation is still in doubt. As a first step to examine the effectiveness, our study aims to assess compliance with the guideline for wildlife crossing construction and management, developed by the Ministry of Environment Korea that provides fundamental information to understand the status and the problem of wildlife crossings in Korea and thus to provide practical guidance for the improvement. According to our survey, the Korea National Park Service complied with the guideline best (62.5%) while local government followed the guideline least (46.1%). In addition, the compliance rate was the highest for wildlife crossings in national roads (53.6%) followed by highways (53.2%) and local and municipal roads (52.2%). For the overpass wildlife crossings, the compliance rates for installation of an escaping facility in the drainage and prevention of pedestrian and vehicle access were particularly low. In case of underpass wildlife crossings, small ditches for amphibians and reptiles were not sufficient, and the linkage between wildlife fences and underpass were weak. In order to ensure the effectiveness of wildlife crossings, the effort to increase the compliance rate with the guideline is critical, and mandating the guideline could be a practical way to enforce the compliance.

The intensive habitats loss of natural organisms as a consequence of anthropogenic activities has lead to the use of alternative habitats for species conservation. We reviewed the current status of alternative habitats and suggest the improvement of alternative habitats. Most of alternative habitats regarded in this study are not following the pre-arranged consultation at environmental impact assessment. These alternative habitats are rendered useless due to the insufficient consideration of ecological characteristics of species and lack of detailed plans. A number of alternative habitats are influenced by disturbance such as environmental pollution and construction. Post-monitoring of alternative habitats are needed to estimate immigration rate of species. Post management is also needed to assess the status of population stability. Overall, low effectiveness of alternative habitats is presented in this study. According to the status survey, methods for improvement of alternative habitats are required such as detailed guidelines, establishment of post-monitoring system, improvement of habitat restoration techniques, and guidelines for management and operation of alternative habitats.

The purpose of this study was to determine the effects of the duration of frying and storage periods on physicochemical characteristics of various oils using at home. The materials used for the study consisted of four kinds of vegetable oils: soybean, canola, extra virgin olive and pure olive oils, and shortening. Chicken breasts were fried in oils heated at $180^{\circ}C$. The oils were stored with or without filtering and reused 3 times, during the 10 day period. The extra virgin and pure olive oils showed higher acid, peroxide value and yellowness than the other oils (p<0.05), but soybean oil showed the highest increase in acid, peroxide value and yellowness with reusing and storage. In sensory evaluation, the chicken breast fried with soybean oils remarkably decreased the overall acceptance. These results suggested that all frying oils are available because acid and peroxide values of the oils are lower than the standard level. However, reusing soybean oil should be noted with caution in that it is very easy to reduce rancidity, and extra virgin olive oil is not appropriate for frying.

Problems and improvement plan in ecological pathways created by Environmental Impact Assessment(EIA) were found based on 504 expost environmental impact survey reports submitted to the National Institute of Ecology in 2016. A total of five improvement plans have been proposed. First, the concept and composition principle of ecological pathways should be unified. Second, Guidelines for consultation on the EIA should be provided for each stage to be applied on-site. Third, if ecological pathway is constructed differently than the consultation, the punishment clauses should be applied to prevent formal composition of ecological pathways. Fourth, We need to prepare measures to strengthen basic research for the installation of ecological pathways. Fifth, We need to strengthen the expost inspection function to compensate for the poorly created of ecological pathways. It is believed that the problems of ecological pathways created by consultation on environmental impact assessment could be corrected in the future. And it is deemed possible to systematically manage ecological pathways.

The goal of work is to Metaphysics (the science of human nature and natureal laws) and Ecology of Gosangugokga<고산구곡가>. Gosangugokga is the harmony of nature and human. The fundamental idea of Metaphysics and Ecology are each same. Gosangugokga is the works of Yunsijo(연시조) by the Yulgok(율곡) and formulated ten-lines. Yulgok was Korean famous a Confucian scholar. His thought summarized that is Likizimyo(이기지묘) Litongkiguk(이통기국). Kiballiseung (기발이승). Yulgok was an espeaially emphasize to the harmony of nature and human. Gosangugokga is the appearance of Yulgok's thought. And so, it is possible throughout Gosangugokga was the metaphysical recognize of ecology. The works of a recognition of residence, the rotation of four seasons. the company with life were the metaphysical recognize of ecology in Gosangugokga. The contents of a Gosangugokga is the fundamental idea of metaphysics. Then, that is the closely related to the ecology. Therefore this dissertation studied the Gosangugokga by investigating a relationship between metaphysics and ecology.
