Mt. Hallasan in Jejudo has been well known as a habitat for both northern and southern limited butterflies and attracts the interests of many lepidopterists. In this study, the line transect method was used to monitor the community and similarity of butterflies monthly monitoring from May to September 2013, and the results were compared with the previous data. Through monitoring, 3,397 individuals in 26 species of 5 families were found in the present study. The monitored individuals belonging to 4 species (Aphantopus hyperantus, Eumenis autono, Lethe diana and Melanargia epimede) was 2,578 (75.9%), showing the prevalent species among the butterflies observed in the grassy area of the Mt. Hallasan. The butterflies inhabiting Mt. Hallasan showed higher similarity in the area where the open grassy space and the crowns of tree layer coexist than in landscape consisting of solely the tree layer or open grassy space. The habitation of butterflies by heights showed the altitudes between 1,665 to 1,700 m, located beneath the Baekrokdam (the crater) of Mt. Hallasan, possessed the most species and individuals. And it was also observed that the species that previously inhabited the subalpine zone moved to the area of higher altitudes together with the species that previously inhabited rather lower altitudes than the subalpine zone.

The three major inventions of Jeju include the field wall of Kim Koo Pan Gwan in 1234, Jeongnang in the custom of grazing the people of Jeju, and Olleh in the tomb of Munbang-gui in 1406. Field wall, Oedam from the stone and the stone of numerical play, made Koendang, a friendship society. Even with a typhoon that is more than 30m/s, the Koendang which is about 1.5m high, will not collapse. Similarly, the main family networks of Jeju society do not collapse under any difficulties situation. When building a field wall, two stones, which are under the ground, are placed side by side, and the upper left stone is placed on top and the upper right stone is attached regularly. One stone or two stone is attached from the bottom to the top, and when a stone is small or large, a flat field is formed in one space. The Family networks is close to the grandfather, grandmother, father, mother, and me, and the distant kin represents a horizontal relationship. The field wall is a vertical relationship that builds up from bottom to top of the vertical relation, while the Koendang is a horizontal relationship where blood is distributed to the grandson of his upper grandparents. This paper proves by a non-orthogonal symmetric weighted Hadamard matrix of whether the stone in the middle of a field wall has large stones (small).

Father, U. Faurie visited Korea (Busan, Incheon, Nampo, Pyongyang, Seoul, Wonsan, Mt. Geumgang of Gangwon-do, and Jeju-do) three times for his plant collections (1901, 1906, and 1907). During his plant explorations, Faurie collected many specimens which were investigated and studied by T. Nakai and H. L$\acute{e}$veill$\acute{e}$ later. Unfortunately all collection sites were simply described in his collection sites in Romanized character, so that it is difficult to pinpoint those sites using the current or old Korean map. From this study, many locality names were reviewed based on his own collections and literatures, and those were listed as the order of his collection dates.

Background: With the recent aging of the population, the transition to a disease structure centered on chronic diseases is accelerating. Moreover, the socio-economic gap and the polarization of the health gap between regions further increase the burden of disease on the country. Accordingly, this study calculated the disease cost of hypertension, diabetes, and hyperlipidemia, which are the three major chronic diseases, to establish an effective health promotion policy strategy for each region, and analyzed the gap in disease cost within the region to determine health determinants at the individual as well as the regional level. Methods: This study utilized data from the 2015 sample cohort of the National Health Insurance Service and calculated the disease cost of patients (diabetes: I10-I15, hypertension: E10-E14, hyperlipidemia: E78) based on the main diagnosis. Results: Based on our analysis, the case of medical use in cities and provinces was higher than in metropolitan cities, with relatively small medical use in Seoul and Gangwon-do. In terms of the disease cost, the cost of chronic diseases in Seoul and Jeju was the highest, but the difference in disease cost between patients in each region was the largest in Seoul and Gangwon-do. Conclusion: The results of this study provide meaningful data for implementing efficient health promotion policies by analyzing the differences in disease cost and identifying health determinants in different regions. Furthermore, in Korea, where socioeconomic differences are clearly revealed, it can be used as a basis for preparing a strategic plan, from a long-term perspective, to improve the health of patients with chronic diseases in the future.

제주도는 연 평균 강우량이 전국 평균의 1.5배에 해당하는 다우지역이다. 그러나 화산섬으로서의 특수한 지형 및 지질구조 때문에 지표수가 거의 발달하지 않았으며, 이러한 수문지질여건으로 인하여 수자원의 대부분을 지하수 개발에 의존할 수 밖에 없어 용수 수요량의 증가를 충족시키기 위한 지하수 개발이 가속화되어 왔다. 그러나 지하수의 과다개발 등으로 지하수의 부존량은 점차 감소할 수 밖에 없는 실정이며, 제주도의 투수성이 높은 지질과 토양으로 지하수 오염에 취약해 최근 수질기준을 초과하는 지역이 늘어나고 있는 실정이다. 이에 제주 당국은 국제자유도시특별법 규정에 권장대상 빗물이용시설에 대한 시설비 보조에 관한 사항 등을 정하여 우수이용을 권장하고 있다. 본 연구에서는 제주도지역의 강우패턴과 세대별 생활용수량 자료를 조사 분석하여 효율적인 가정용 우수 이용 시스템으로서 갈수기에도 안정적으로 용수를 공급받을 수 있는 저류탱크의 크기 및 우수배관의 관경결정 기법을 개발하고 수질의 안정화를 위한 우수수질 안정화 기법을 제시하였다. 우수이용 시스템의 설계를 위하여 개발한 모형인 DDP, DOS 모형을 이용하여 강우 및 용수의 기초자료가 비교적 풍부한 제주도 지역에 적용함으로써 국내의 다른 산간지역과 도서지역에서도 본 시스템의 적용이 용이하게 될 수 있을 것으로 판단되며, 본 시스템 및 시스템 모형화에 대한 지속적인 연구를 통하여 보다 경제적이고 안정적인 시스템 설계가 가능한 범용적인 모형의 개발을 할 수 있을 것으로 사료된다.

Recently, domestic animal disease caused tremendous damage to farmhouses and the damage stretched in nationwide with the spread of epidemic disease. To prevent animal diseases from happening again, the system development to easily measure the temperature of sick animals and identify of them is needed, thereby quickly treat them, reducing losses of farmhouses. However, a lack of related equipment and human resource hampered its effort to minimize its losses. This study tries to develop diagnosis system as part of measures to curb these domestic animal diseases. This paper present the 센서 node based on IEEE 802.15.4 which can be attached to the animal body for real-time temperature measurement. We design and implement tiny chip-type that can be attached to the body of animals. Then, we use available power only when measuring temperatures in a long term-basis. In this paper, the 센서 node was applied to horse's neck. We measure the horse's body temperature between $32.2^{\circ}C{\sim}33.7^{\circ}C$ and analyze phenomenon data for 4 months.

The purpose of this study is to ascertain the actual conditions of volunteering activities in respect to age-integrated leisure. This study is based on the 2010 Korea Leisure Life Survey. The participants in this study were 3015 people who reside in Korean cities, except for Jeju-do. Questionnaires from the 2010 Korea Leisure Life Survey were used for the final analysis. Data were analyzed through a descriptive analysis, Chi-Square test and ANOVA by SPSS WIN 17.0. The findings indicated that 18% of the participants participated in volunteer activities as leisure in the last one year. The major findings were as follows. First, demographic characteristics such as age, academic career, income, and marital status had a positive correlation with the degree of volunteer participation. Second, there were differences in duration and field of activities according to age. Third, though most of the non-volunteer reasons were 'lack of resources', there were different reasons based on age. In detail, the reason for 10-50 year-olds (economically active population) was 'lack of time', but the more than 60 year-olds was 'health concern'. Consequently, this access to the life cycle study shows the need to improve life satisfaction.
