Primary pulmonary amyloidosis is a rare disorder. It can be classified into tracheo-bronchial, diffuse alveolar septal and nodular parenchymal form. Tracheo-bronchial amyloidosis can be further subdivided into diffuse and focal varieties. We report a case of diffuse tracheo-bronchial amyloidosis in a 49-year old man comfirmed by broncos-copic biopsy. He has suffered from cough and exertional dyspnea over 20 years and recently atelectasis of fright middle and lower lobe was found on chest X-ray with aggravation of symptom. The chest CT showed irregular thickening of tracheo-bronchial wall with calcification in addition to collapse of right middle and lower lobe. The bronchoscopy showed multiple variable sized submucosal nodules in lower trachea and both sides of bronchi, and biopsy revealed amyloid deposition at the subepithelial layer. We discussed this case with review of literature.

Interests in ecosystem services have increased and a number of attempts to perform a quantitative valuation on them have been undertaken. To classify the ecosystem types landcover classification maps are generally used. However, some forest types on landcover classification maps have a number of errors. The purpose of this study is to verify the forest types on the landcover map by using a variety of field survey data and to suggest an improved method for forest type classifications. Forest types are compared by overlaying the landcover classification map with the 4th forest type map, and then they are verified by using National Forest Inventory, 3rd National Ecosystem Survey and field survey data. Misclassifications of forest types are found on the forest on the forest type map and farm and other grassland on the landcover map. Some errors of forest types occur at Daegu, Busan and Ulsan metropolitan cities and Gangwon province. The results of accuracy in comprehensive classification show that deciduous forest is 76.1%; coniferous forest is 54.0%; and mixed forest is 22.2%. In order to increase the classification accuracy of forest types a number of remote sensing images during various time periods should be used and the survey period of NFI and the National Forest Inventory and National Ecosystem Survey should be consistent. Also, examining areas with wide forest patch should be prioritized during the field survey in order to decrease any errors.

최근, 새천년생태계평가(MA: Millenium Ecosystem Assessment), 생태계와 생물다양성의 경제학(TEEB: The Economics of Ecosystems and Biodiversity) 등의 체계에 따라 생태계서비스를 평가하는 연구가 활발히 이루어지고 있다. 그러나 기존 대부분의 연구에서는 생태계기능 평가량에 화폐적 가치를 곱하여 생태계서비스를 평가하고 있어 생태계서비스와 관련된 환경 및 사회경제적 조건을 반영하지 못하고 있다. 본 연구에서는 자연 및 사회경제적 요소를 반영한 생태계서비스 평가방안을 제시하고자 하였다. 우선, 수원함양기능을 InVEST의 Water Yield 모형을 통해 평가하였고 수원함양기능에 강수량과 인구를 반영하여 수원함양의 생태계서비스를 평가하였다. 평가결과, 토지피복, 토양 등의 자연조건을 반영한 수원함양기능과 강수량 및 인구 등의 기후 및 사회경제적 인자를 추가적으로 고려한 생태계서비스의 공간분포는 서로 다른 양상을 보였다. 즉, 같은 수원함양기능을 보인 지역이라도 강수량이 적고 인구가 많은 지역에서 수원함양의 생태계서비스가 높은 것으로 나타났다. 본 연구를 통해 수원함양의 생태계서비스는 수원함양기능에 추가적으로 기상 및 사회경제적 인자를 고려하여 평가되어야 한다는 것을 제시하였으며, 평가과정은 다른 분야의 생태계서비스평가에 유용하게 활용될 것으로 기대된다. The study of ecosystem service assessment has been actively researched and developed from Millennium Ecosystem Assessment(MA) and The Economics of Ecosystems and Biodiversity(TEEB). However, current assessments are limited to monetary assessments of ecosystem function and do not account for the effects of environmental factors and socioeconomic status. This study proposes methods to evaluate ecosystem service based on environmental and socioeconomic factors. The study assesses water yield function through the water yield model in InVEST Tool, and evaluates the overall ecosystem service of water yield as reflected by the amount of precipitation and population of the area. Results show that a difference exists between spatial distributions of the ecosystem function of water yield derived from natural conditions such as land cover and soil, and the spatial distribution of the ecosystem service that accounts for climate and socioeconomic factors. The value of ecosystem service increases for an area of higher population and lower precipitation with similar water yield. Thus, the ecosystem service of water yield should be evaluated not only by the water yield function, but also by climate and socioeconomic factors. The evaluation process described for this study should also be applicable to the evaluation of ecological services in other sectors.

The provided habitat of many services from natural capital is important. But because most ecosystem services tools qualitatively evaluated biodiversity or habitat quality, this study quantitatively analyzed those aspects using the species distribution model (MaxEnt). This study used location point data of the goat(Naemorhedus caudatus), marten(Martes flavigula), leopard cat(Prionailurus bengalensis), flying squirrel(Pteromys volans aluco) and otter(Lutra lutra) from the 3rd National Ecosystem Survey. Input data utilized DEM, landcover classification maps, Forest-types map and digital topographic maps. This study generated the MaxEnt model, randomly setting 70% of the presences as training data, with the remaining 30% used as test data, and ran five cross-validated replicates for each model. The threshold indicating maximum training sensitivity plus specificity was considered as a more robust approach, so this study used it to conduct the distribution into presence(1)-absence(0) predictions and to talled up a value of 5 times for uncertainty reduction. The test data`s ROC curve of endangered mammals was as follows: growing down goat(0.896), otter(0.857), flying squirrel(0.738), marten(0.725), and leopard cat(0.629). This study was divided into two groups based on habitat: the first group consisted of the goat, marten, leopard cat and flying squirrel in the forest; and the second group consisted of the otter in the river. More than 60 percent of endangered mammals` distribution probability were 56.9% in the forest and 12.7% in the river. A future study is needed to conduct other species` distribution modeling exclusive of mammals and to develop a collection method of field survey data.

We investigated the insect community along altitudinal gradient to gather basic data for distributional monitoring of insect species in the forest ecosystem. The investigation area was Seon-gaksan (Mt.) in Jinan-gun, Jeollabuk-do province, where the bucket-light trap and pit-fall trap for quantification were installed in Quercus vegetation at altitude of 300m, 600m and 900m. The field collecting was performed on May, July and September 2013 respectively. ANOVA analysis was conducted to analyze the significance between insect species along altitude using the collected insect community data. Analysis of variance (ANOVA) results showed statistically significant differences among ground-beetles and ants abundance with altitude as a response variable. Although we expected a distinct cluster with the difference of altitude at each study site, nonmetric multidimensional scaling (NMS) showed distinct clusters with the moth, ground-beetles, and ant assemblage at altitudinal increase and sampling month. In the result, a total of 309 species in 18 families of nocturnal moths were collected by bucket-light trap. The insects collected in pit-fall trap were ground-beetles with 196 individuals of 26 species and ants with 11,276 individuals of 14 species respectively.

<P>A new peptide, gombamide A (<B>1</B>), was isolated from the marine sponge <I>Clathria gombawuiensis</I>, collected from Korean waters. On the basis of the results of combined spectroscopic analyses, the structure of this compound was determined to be a cyclic C-terminally modified thiohexapeptide containing the unusual amino acid residues <I>para</I>-hydroxystyrylamide (<I>p</I>HSA) and pyroglutamic acid (pyroGlu). The absolute configurations of all amino acid residues were determined to be <SMALL>l</SMALL> by advanced Marfey’s analysis.

이 연구는 초등학교 5~6학년 학생들 중 비만인 여학생들을 대상으로 16주간 발레 프로그램이 비만 여학생들의 신체구성 및 등속성 근력에 미치는 영향을 구명하고자 실행되었으며, 청소년기 때부터 비만관리 및 체력과 체격을 위한 프로그램의 새로운 개발과 발레지도자들에게 과학적인 기초자료를 제공할 목적으로 연구를 하였다. InBody 720을 이용하여 신체조성을 측정 하였고 등속성 근력장치(CYBEX, USA)를 이용하여 부하속도는 60°/sec에서 슬관절 근력을 측정하였다. 비만 초등학생에게 발레 프로그램을 8주, 16주간 실시한 결과 다음과 같은 결과를 얻었다. 발레참여는 8주와 16주에서 체지방률, 체지방 감소와 근육량의 증가에 영향을 미쳤다(p<.01). 참여기간에 따른 사후검증에서 체지방률, 체지방,근육량 모두 16주에서 가장 큰 차이를 나타냈다. 또한 발레참여(8주, 18주)는 무릎의 신근 오른쪽과 왼쪽 최대근력의 증가에 영향을 미쳤다(p<.05). 참여기간에 따른 사후검증에서 최대근력과 체중당최대근력 또한 16주에서 가장 큰 차이를 나타냈다. 이와 같은 결과로 보아 16주 이상의 발레프로그램 참여는 비만 여자학생들의 신체구성과 등속성 근력의 향상에 효과적인 결과를 얻을 수 있었다. 앞으로 이를 토대로 비만 여자초등학생을 위한 재미있고 생동적인 발레프로그램을 개발하여 초등학생의 비만을 줄이고, 더욱 활기차고 긍정적인 학교생활을 보낼 수 있도록 도움을 주어야 할 것이다.
