  • A mural was discovered in the Ssanggyesa temple located in Jindo island, during repair of the Daeungjeon Hall. A study was conducted to determine the binding medium used for preparing the mural. Pyrolysis/GC/MS and IR spectrometry were used to analyze a painting specimen. Direct approach and on-line methylation approach were attempted for the pyrolysis/GC/MS. In IR analysis, the spectra of the specimen were found to be different from those of Asian lacquer, yellow lacquer, animal glue, and acrylic emulsion resin. They were also not identical to the standard IR spectra of drying oils such as linseed oil. Pyrolysis/GC/MS results of the specimen were different from those of Asian lacquer, yellow lacquer, animal glue, and acrylic emulsion resin. In the mean time, palmitic acid, octadecanoic acid, nonanedioic acid, and octadecenoic acid, which are characteristic pyrolysis products of dried drying oil, were detected. In addition, the pyrolysis/GC/MS chromatograms of the specimen and dried drying oil were also very similar. Therefore, it was concluded that the painting was prepared using drying oil as a binding medium.

  • PURPOSE: This study aimed to provide supporting data for the clinical use of breathing exercise with a WBV stimulation as a sustained and safe intervention program, by examining the effect of breathing exercise with WBV stimulation on the pulmonary function, gait ability, and life quality in patients with severe chronic obstructive pulmonary disease (COPD), who have difficulty performing exercise. METHODS: For this study, after collecting the samples from 20 patients with severe COPD, they were placed randomly in an experimental group to perform breathing exercises with a WBV stimulation (n = 10) and a control group to perform breathing exercises only (n=10). Before the intervention, pulmonary function, six-minute gait distance, and health-related life quality were measured as pre-tests. After applying the intervention program to the patients for 30 minutes once a day, for four days a week, for six weeks, the post-test items were remeasured in the same way as the pre-tests, and the results were analyzed. RESULTS: In the within-group comparison, both the experimental and control groups showed significant differences in the forced expiratory volume in one second, six-minute gait distance, and health-related life quality (p < .01) (p < .05). In the intergroup comparison, there were significant differences in the forced expiratory volume in one second and the six-minute gait distance (p < .05). CONCLUSION: WBV stimulation was more effective for the patients by improving the muscular strength and muscular endurance through the reflexive contraction of muscles, and increasing the exercise tolerance. This result could serve as an alternative means to clinically improve the physical function of patients with severe COPD, who have difficulty performing breathing exercises in the future.

  • 토양은 육상생태계에 있어 가장 많은 탄소를 저장하고 있으며, 대기 중 CO2를 토양탄소로 전환하여 쉽게 방출되지 않고 토양 내에 저장하는 역할을 한다. 이렇듯 토양 유기탄소 배출관리는 기후변화에 있어 중요한 문제로 대두되고 있다. 하지만 토지이용의 변화와 무분별한 관리로 인하여 토양내에 저장되어 있는 토양 탄소배출이 지속적으로 증가 하고 있다. 따라서 토양탄소 배출로 인한 경제적 피해를 수치적으로 표현하는 가치평가가 필요하다. 현재 토양에 저장된 토양유기탄소 함량을 토양통별로 토양정보시스템에서 제공하고 있지만 국내 토양 토양탄소 저장량의 산정에 관한 연구는 미비한 실정이다. 따라서 본 연구에서는 토양 특성을 이용하여 토양 유기탄소 저장량을 산정하고, 산정된 토양 유기탄소 저장량과 정밀토양도를 이용하여 남한의 토양 유기탄소 가치평가를 실시하였다. 토양의 특성은 물리적 특성인 모래(Sand), 이토(Silt), 점토(Clay), 자갈(Gravel)함량과 화학적 특성인 유기물함량(Organic Matter)를 사용하였다. 토양 유기탄소저장량 산정의 검증을 위하여 전라남도 진도군의 토양유기탄소 저장량을 산정한 결과 486,696t으로, 선행연구와 유사한 결과를 나타내었다. 이러한 검증 결과를 바탕으로 남한의 토양 유기탄소 저장량을 산정한 결과 305.54Mt의 유기탄소가 저장된 것으로 나타났으며, 단위 면적당 유기탄소 저장량의 경우 3.11kg/㎡으로 나타났다. 또한 2019년 상반기 기준 평균 탄소거래권 가격(27,500원/톤)을 이용하여 우리나라 국토의 토양탄소 저장량 가치평가를 실시한 결과, 약 8조 4천억원의 경제적 가치가 있는 것으로 나타났다. 본 연구는 토양의 물리적·화학적 특성을 이용하여 토양의 유기탄소 저장량을 산정하였으며, 토양에 저장되어 있는 유기탄소의 가치평가를 수행하였다. 본 연구결과는 농업, 수문, 기후변화 등 다양한 분야에서 필요로 하는 기초자료로 활용될 수 있을 것으로 판단된다.

  • The head of the Jindo, Korean native dog was measured in the present study. One hundred and ninety five Jindoes were randomly selected from the 1,985 dogs in the Jindo County in August 1998, which were screened by the judging committee of the County and registered by inserting electronic chips in the withers. They were about one and a half-year-old, and were white and fawn dogs. The head was divided into three parts; the skull, ear and nose. Each part was divided again, and a total of 14 parts of the head were measured using calipers. Measurements of the skull part and skull index were bigger in dogs than in bitches, but no differences were found between sexes. No differences were found in the measurements of the ear part between sexes or coat colors, except the distance between two ears in which the distance was longer in dogs than in bitches. In the measurements of the nose, the width of rostral part was larger in fawns than in whites and in dogs than in bitches. The rest were larger in dogs than in bitches.

  • The landscape systems in Korean island settlements can be recognized as results of ingabitants' ecological adptation to the isolated environment with the limited natural resources. Both the fishery dominant industry in island society and ecological nature of its environments seem to have influenced on inhabitants' environmental cognition as well as the physical landscape of island villages such as its location, spatial pattern in each village, housing form and so on. This study was done mainly by both refering to the related documents and direct observations in case study areas, and results of the study can be summarized as follows. 1. In general, the landscape of an individual island seems to take more innate characteristics of island's own, corresponding to the degree of isolation from mainland. That is, while the landscape of island in neighboring waters takes both inland-like and island-innate landscape character at the same time, the one in the open sea far from land takes more innate landscape character of all island's own in the aspects of village location, land use and housing density etc. 2. The convex landform of most islands brings about more centrifugal village allocation than centripetal allocation in most inland villages. And thus most villages in each island face extremely diverse directions different from the south facing preference in most inland rural villages. 3. Most island villages tend to be located along the ecologically transitional strip between land and sea, so called 'line of life', rather than between hilly slope and flat land as being in most inland village locations. So they are located with marine ecology bounded fishing ground ahead and land ecology bounded agricultural site at the back of them. 4. The settlement pattern of the island fishing villages shows more compact spatial structure than that of inland agricultural villages, due to the absolute limits of usable land resources and the adaptation to the marine environment with severe sea winds and waves or for the easy accessability to the fishing grounds. And also the managerial patterns of public owned sea weed catching ground, which take each family as the unit of usership rather than an individual, seem to make the villagescape more compact and the size of Individual residence smaller than that of inland agricultural village. 5. The folk shrine('Dand') systems, in persrective of villagescape, represent innate environmental cognition of island inhabitants above all other cultural landscape elements in the island. Usually the kinds and the meanings of island's communal shrine and its allocative patternsin island villagescape are composed of set with binary opposition, for example 'Upper shrine(representing 'earth', 'mountain' or 'fire')' and 'Lower Shrine(representing 'sea', 'dragon' or 'water') are those. They are usually located at contrary positions in villagescape each other. That is, they are located at 'the virtical center or visual terminus(Upper shrine at hillside behind the village)' and 'the border or entrance(Lower Shrine at seashore in front of the village)'. Each of these shirines' divinity coincides with each subsystem of island's natural eco-system(earth sphere vs marine sphere) and they also contribute to ecological conservation, bonded with the 'Sacred Forest(usually with another function of windbreak)' or 'Sacred Natural Fountain' nearby them, which are representatives of island's natural resources.

  • In this study, endophytic fungi were isolated from the roots of three native orchid species from Korea: Bletilla striata, Oreorchis patens, and Cephalanthera longibracteata. The isolated fungal endophytes were identified based on the morphological and molecular characteristics including sequence analysis of internal transcribed spacer (ITS) and 28S ribosomal DNA regions. As a result, we discovered 5 species of fungal endophytes that have not been previously reported in Korea: Phialocephala bamuru, Coniochaeta mutabilis, Phialophora foetens, Calonectria canadensis, and Neonectria ramulariae.
