The purpose of this study is to quantitatively evaluate the amount of carbon storage for trees in forest ecosystem to support the foundation for carbon neutrality implementation in Korea National Park. It targeted 22 national parks designated and managed as national parks in Korea, and conducted research on forest trees in the terrestrial ecosystem among various natural and ecological carbon sink. The survey and analysis method followed the IPCC guidelines and the National Greenhouse Gas Inventory in Korea. The amount of tree carbon storage in the forest ecosystem of Korea National Park was confirmed to be about 218,505 thousand CO₂-ton and the amount of carbon storage per unit area was 570.8 CO₂-ton per hectare. Compared to 299.7 CO₂-ton per hectare, the average carbon storage per unit area of the entire Korean forest, it was found that about twice as much carbon was stored when assuming the same area. In other words, it means that the tree carbon storage function of the national park is about twice as high as that of the average tree carbon storage function of entire Korean forest. It has great implications in Korea National Park not only provides biodiversity promotion and exploration services as a national protected area, but also performs excellent functions as a carbon sink.

국립공원은 주로 산악 지형 내 조성되어 있으므로 산사태에 의한 피해 가능성을 항상 내포하고 있다. 본 연구는 산사태 연구의 일환으로 국립공원 탐방로 내 위험 급경사지를 체계적으로 유지관리하기 위한 방안을 마련하는데 목적이 있다. 국립공원에 특화된 자체 체크리스트를 제작하였으며, 전국 19개 국립공원 183개소 급경사지에 대한 실태조사가 이루어졌다. 실태조사의 최종 목적은 위험 급경사지에 대한 안정화 대책을 마련하는 것으로 현장조사와 안정해석의 과정을 거친다. 일부 급경사지에서는 위험성 판단을 위해 지상라이다 등 특수 장비를 이용한 조사를 시도하였다. 중장기 정비계획을 위한 투자우선순위 공식을 개발하였으며, 현장자료를 이용한 순위 및 위험등급을 산출하였다. 최종적으로 위험 급경사지의 향후 체계적인 관리를 위해 “국립공원 급경사지 유지관리시스템”을 개발하였으며, 모든 현장자료들은 시스템 내 DB화 되었다. National parks, which are located mainly in mountainous areas, are always at risk of damage by landslides. The goal of this study is to establish a method for systematically maintaining hazardous steep slopes along trails in national parks. We produced a checklist suitable for each of the 19 national parks nationwide and investigated 183 slopes. The aim of these investigations is to recommend appropriate slope-stability countermeasures, including field investigations and stability analysis. We made preliminary investigations at specific sites, evaluating the slope hazard using specialized equipment such as terrestrial LiDAR. An investment priority formula was developed, and ranking and hazardous grades were calculated as part of a long-term maintenance plan. Finally, to systematically manage dangerous slopes and to house all the field data within one system, we developed the “Slope Maintenance System in National Parks” based on web server that can show various information for slopes.

논문 : 1920년대 초기 『조선일보』 「문예란」 연구 -발굴과 위상의 구명

박현수 ( Hyun Soo Park ),홍현영 ( Hyun Young Hong ) 민족문학사학회·민족문학사연구소 2015 민족문학사연구 Vol.57 No.-

『조선일보』의 「문예란」은 1921년 7월 4일부터 같은 해 8월 27일까지 『조선일보』1면에 개설되었다. 이 글의 목적은 『조선일보』 「문예란」에 실린 작품들을 발굴, 소개하고, 그 위상을 구명하는 것이다. 「문예란」이 개설되었던 때는 『조선일보』가 23회에 이르는 발매반포금지와 2차례의 정간을 겪고 점차 운영에서 정상을 찾아가던 즈음이었다. 「문예란」은 총 38회 개설되었는데, 시가 21편, 평론이 3편, 기행문이 1편, 수필이 1편 등 모두 26편의 작품이 실렸다. 「문예란」에 글을 수록한 작가는 변영로, 남궁벽, 김억, 박종화, 오상순, 오천석, 김찬영, 현진건 등이다. 변영로는 「문예란」에서 가장 활발한 작품 활동을 했으며 필자들의 교류에서도 중심에 있었다. 그는 진리가 확정된 세계에서 벗어나 불확실성에 투신하는 자세를 새롭게 창출될 문학의 핵심이라고 주장했다. 이 글은 남궁벽이 스스로 ``∼다``체로 번역해 발표한 「별의압흠」, 「말」 등을 소개하는 것을 통해 정본 확정의 문제를 제기했다. 또 작가의 과작을 고려할 때 새롭게 발굴, 소개하는 남궁벽의 시 5편이 지니는 무게 역시 가볍지 않다. 박종화의 시 가운데 「廢園에누어셔」는 「黑房秘曲」에 실린 시와 달리 3장으로 되어 있다. 특히 3장이 당시 박종화의 지우였던 정백, 홍사용 등의 갈등과 관련되어 주목을 필요로 한다. 이 글에서 소개하는 오상순의 두 시 역시 처음 발굴, 소개하는 시들이다. 이들은 어린 시절의 상상력이 깃든 언어를 가장 본질적인 것으로 파악하는 당시 오상순의 문학관을 드러내고 있다. 「문예란」의 필자들은 이미 문단의 승인을 받은 존재들이었다는 점에서 작품들 역시 문학청년 시기의 습작이나 투고작과는 다르다. 또 「문예란」의 필자는 각각의 동인지에 얽매이지 않는 문인들의 네트워크와 문학 활동을 파악할 수 있는 대상이기도 하다. 「문예란」이 지닌 가장 두드러진 의미는 『조선일보』를 비롯해 『동아일보』 『매일일보』 등 당시 신문 미디어에 같은 성격의 지면이 존재하지 않았다는 점에 있다. Literary section in Chosun Ilbo was first open on July 4, 1921 and lasted until on August 27 in the same year. The section was reported on the first page of Chosun Ilbo. The purpose of this article was to discover and introduce the pieces of literary work reported in Chosun Ilbo, and to bring light on the status of its literary section. The time when literary section was established was the moment Chosun Ilbo was returning to normal condition of running business after having twenty three times of prohibition of release and two times of suspension. The number of reported literary section was thirty eight, which included twenty one pieces of poem, three pieces of critique, one piece of travel essay, and one piece of essay. Thus, the total number of reported literary work was twenty six. Writers who participated in the section were as followed : Young-Roh Byun, Byuk Namgung, Uk Kim, Jong-Hwa Park, Sang-Soon Oh, Chun-Seok Oh, Chan-Young Kim and Jin-Gun Hyun. Among them, Young-Roh Byun was the most active writer in the literary section and was in the center of mutual exchange of opinion among the writers. He sought the core of literature in the attitude that was devoted to the uncertainty, which was off the world of concrete truth. This article supposed a question on determination of the formal copies by discovering and introducing the Byul-eui-ap-hem(별의압흠), and Mal(말) which were reported by Byuk. He translated these pieces for himself using style of writing, "∼ da". Moreover, as Namgung was not a prolific writer, the importance of five pieces of poem by Byuk Namgung should not be overlooked. Park`s poem, Lying in the closed garden(廢 園에누어셔), consisted of three chapters compared to that of his, which were issued in Secret songs in a black room(黑房秘曲). Especially, the third chapter of it was related to conflict among his companions, Baek Jung and Sah-Yong Hong. Therefore, it needs to be focused on that chapter. Two pieces of poem by Sang-Soon Oh were introduced for the first time. These represented Oh`s literary view at the moment, which the writer understood the language with childhood imagination as the most essential one. Writers of the literary section had already been approve by the literary circle. For this reason, the pieces reported in the literary section had a different character from their studies or submission before starting their literature career. In addition, the writers were the subject of the network and career activities among the writers who were not bound by literary coterie magazines. The most significant meaning of literary section was that the section with the same character did not exist in Dong-A Ilbo, Maeil Shinbo, or Chosun Ilbo itself. To prove this point, relation between news media and literature in early 1920s was discussed.

홍길표(Gil-Pyo Hong),빙기창(Gi-Chang Bing),조숙영(Sook-Young Cho),박세영(Se-Young Park),김양모,권영수(Young-Soo Kwon) 국립공원연구원 2013 국립공원연구지 Vol.4 No.1

국립공원 내 주요 철새중간기착지의 철새이동 현황을 비교하기 위해 동시 조사를 실시하였다. 조사 지역은 다도해해상국립공원의 흑산도와 한려해상국립공원의 소매물도 지역이며, 조사 기간은 2013년 4월 29일~5월 2일까지 4일간 실시하였다. 조사결과 2개 지역에서 총 109종 2,537개체가 기록되었으며, 지역별로는 흑산도에서 96종 1,615개체, 소매물도에서 45종 922개체가 조사되었다. 흑산도에서는 제비 Hirundo rustica가 최우점종이었으며, 소매물도에서는 괭이갈매기 Larus crassirostris가 최우점종으로 조사되어, 지역별로 우점종의 구성이 다른 것으로 나타났다. 국립공원내에 위치한 철새중간기착지에서의 동시 조사는 본 조사가 처음이다. We performed simultaneous survey in order to compare the status of migratory birds at stopover sites in National Park. The study areas were Heuksan-do in Dadohaehaesang National Park and Somaemul-do in Hallyeohaesang National Park from 29 April to 2 May in 2013. We observed total 109 species, 2,537 individual. In two regions, 96 species, 1,615 individuals were observed in Heuksan-do and 45 species, 922 individuals observed in Somaemul-do. The dominant species was the Barn Swollow Hirundo rustica in Heukan-do and the Black-tailed Gull Larus crassirostris in Somaemul-do. Domiant species differed between two regions. This study is the first time to monitor stopover sites simultaneously in Korea National Park.

This paper concerns IF-stage and data recovery as a basic study for home products of GPS receiver. Using a transmission simulator, the same data can be received as transmission simulator transmits. Consequently, it is considered that IF-stage and the part of data recovery operate fairly good and attaching microprocessor control and time interval counter to this system will operate better. It can be expected that providing the system with RF-stage and antenna will be complete GPS receiver.

생분해성 폴리락타이드/폴리에틸렌글리콜 공중합체 마이크캡슐의 제조와 방출거동에 대한 연구

박수진,김승학,홍성권 한국화학공학회 2003 Korean Chemical Engineering Research(HWAHAK KONGHA Vol.41 No.4

본 연구에서는 생분해성 poly(L-lactide) (PLA)/poly(ethylene glycol) (PEG) 마이크로캡슐을 액중건조법으로 제조하고, PLA 마이크로캡슐에 PEG를 첨가함에 따른 분해거동, 크기분포 그리고 방출거동에 미치는 영향을 살펴보았다. 그 결과, PLA/PEG 공중합체는 PLA보다 친수성이 크게 나타났고, 낮은 유리전이 온도를 가짐을 알 수 있었다. PLA/PEG 마이크로캡슐의 표면은 PLA 마이크로캡슐보다 부드럽지 못했고, 제조된 PLA와 PLA/PEG 마이크로캡슐의 평균크기는 40과 57 ㎛이었으며, 또한 구형의 형태를 나타내는 것이 image analyzer와 SEM을 통하여 관찰되었다. PLA/PEG 마이크로캡슐의 약물 방출거동은 UV/Vis. spectra를 통하여 살펴보았고, 방출 속도는 PEG의 첨가에 따라 두드러지게 증가하였는데, 이는 친수성기의 증가와 PEG의 팽윤성으로 설명되어질 수 있다. In this work, biodegradable poly(L-lactide) (PLA)/poly(ethylene glycol) (PEG) microcapsules were prepared by emulsion solvent evaporation method. The effect of PEG segments on the degradation, size distribution, and release behavior of the microcapsules was studied. According to the experimental results, PLAPEG copolymers were more hydrophilic and exhibited lower glass transition temperatures compared to PLA homopolymer. The surface of PLAPEG microcapsules was not as smooth as that of PLA microcapsules. The mean diameters of the PLA and PLA/PEG microcapsules were 40 and 57 pm, respectively. The spherical forms were observed by image analyzer and scanning electron microscope (SEM). Drug release from microcapsules was determined by UV/Vis spectra. It was found that the drug release rates of the microcapsules were significantly increased with adding of PEG, which could be attributed to the increase in their hydrophilicity and swelling characteristics.

Fibronectin처리 탈회상아질편 이식이 골결손부 치유에 미치는 영향

박홍락,김진수 慶北大學校 齒科大學 1990 慶北齒大論文集 Vol.8 No.1

The purpose of this investigation was histologic evaluation of the fibronectin treated-decalcified dentin for the repair of bony defects. Thirty holes, 10㎜ in diameter and 5㎜ in depth were made in the mandibles of 8 adult dogs weighing about 15㎏. The decalcified dentin were prepared as descrebed by Inoue. Ten empty holes without any implant were served as control 1 group. The dentin cubes treated without fibronectin were implanted into the 10 holes, that was classified as control 2 group, and the remaining 10 holes prepared with fibronectin-treated decalcified dentin were served as experimental group. The animals were sacrificed serially at the interval of 1,2,3,5, and 8 weeks. Serial sections of all specimens were prepared and examined by routine histologic methods. The results were as follows: 1. During early experimental periods, there was a little evidence of specific inflammatory and rejective reponses caused by fibronectin-treated decalicified dentin allografts. 2. The bony repair of fibronectin treated, decalcified dentin allografts implanted wounds was more favorable than fibronectin nontreated, decalcified dentin allografts implanted wounds; by early replacement of fibrin mesh, increased connective cell proliferation, and reduction of the inflammatory response. 3. Fibronectin treated, decalcified dentin allografts revealed good osteoinductive potential. From 3 weeks after implantation, direct osteogenesis around the dentin allografts was remarkable, and with time the dentin allografts were gradually replaced by mature bone. 4. The above findings confirm the value of fibronectin treated, decalcified dentin allograts in promoting regeneration of bone and support their clinical use in treatment of bony defects. J.
