저작근 골막하 박리를 이용한 만성 재발성 탈구의 치험례
심재환,김기홍,문진석,민병진,이원학,홍광진 大韓顎顔面成形再建外科學會 2003 Maxillofacial Plastic Reconstructive Surgery Vol.25 No.3
Chronic recurrent dislocation(CRD) of the jaw has various etilogical causes, including trauma, congenital or acquired neurological illness, ingestion of certain medicines, incorrdination of the neuromuscular astivity of the chewing muscles, articular anatomical alteration, etc. Various surgical methods have been advocated for the treatment of the CRD. They may be divided into two groups: procedures designed to limit translation of the condyle and procedures eliminating obstacles in the condylar path. Hypomobility of mandible can be developed after BSSRO and it is probably caused by scar contracture, atrophy, and myofibrosis. Many authors, therefore, emphasized the importance of physical therapy especially after BSSRO to prevent the complication. Based on that idea, we designed more conservative surgical method to limit mandibular openning compared the methods that previously introduced and tried to treat the CRD. This new method consists of extensive subperiosteal dissection of masseter and the temporalis muscle under local anesthesia and use of intermaxillary elastics for some periods.

The objective of this study was to propose the best methodology for estimating soil organic carbon stocks during environmental assessment for development projects. We compared three methodologies which were developed by Korea Environment Corporation(2010), Korea Forest Research Institute (2006), and Jin-Hyun Jung (1998). We found that the methodology developed by Jin-Hyun Jung (1998) shows the worst performance and the methodology of Korea Forest Research Institute (2006) does not reflect a variety of soil types and land use characteristics shown in development project plans. Therefore, we propose that the methodology developed by Korea Environment Corporation (2010) is the most reasonable one because it is internationally accepted and used for local governments to make the inventory of greenhouse gases as well as to set up its reduction strategy.
무증상으로 발견된 담낭-담관 누공을 동반한 Mirizzi 증후군 1예
홍진희,전태주,서지영,서동대,오태훈,신원창,최원충,신은아,김기환 인제대학교 2009 仁濟醫學 Vol.30 No.-
Mirizzi's syndrome is a rare complication of the gallstone disease, characterized by narrowing of the common bile duct (CBD) due to chronic extrinsic compression of an impacted gallstone in the cystic duct or the neck of the gallbladder. The impacted gallstone may erode into the bile duct, causing cholecystocholedochal fistula. The patients generally have history of repeated attacks of jaundice and abdominal pain. But there is no report about asymptomatic Mirizzi syndrome with cholecystocholedochal fistula which were found incidentally. So herein we present our clinical experience with a case of asymptomatic Mirizzi syndrome with cholecystocholedochal fistula in a young female.

The interactions between Environment-Friendly Agriculture Research Center (EFARC) and farmers in Jeonnam Province area who have practiced environment-friendly agriculture (EFA) under guidances of EFARC were investigated through enquete. The enquete was conducted during July - September, 2010. One hundred and eighty nine farmers responded all inquiries among 200 farmers. The main results are summarized as follows: 1. Rice was the predominant crop grown by farmers (49%), and the next major was hot pepper (12%). Most farmers (95.3%) have practiced environment-friendly agriculture at the levels of no-pesticide (55.6%), lower pesticide (32.8%), and organic (6.9%). 2. Major motivations of practicing EFA are for the production of safe foodstuffs (52.6%) and for an increase of income (40.1%). 3. Around 3 quarters of the environment-friendly agriculture products are shipped through Nonghyup, the cooperative marketing. The price margin between ordinary agriculture products and EFA products was of 5~10% for 63.5% farmers, of 10~20% for 14.3% ones, and of 20~30% for 14.8% ones. 4. Bottlenecks for practicing EFA are in the order of the unstability of shipping price (34.9%), cultivation techniques (20.1%), excess labor input (19.6%), and control of disease and insect pest (18%). 5. It turned out that more than 90% farmers who have practiced EFA under guidance of EFARC recognized the consulting activities of EFARC as to be helpful for them. 6. Establishment of national organizations which are specialized in consultation for EFApracticing farmers has been suggested.

32개 點群은 中心對稱(centrosymmetric)을 갖는 11가지 點群(Laue群)과 21個의 非對稱中心(noncentrosymmetric)點群으로 이루어졌다. 本 硏究에서는 21個 非對稱中心點群 各各의 等價回折面(等價逆格子點)들을 誘導하였다. The thirty two point groups consist of eleven Laue groups (centrosymmetric point groups) and twenty one noncentrosymmteric point groups. In this paper, the reciprocal lattice points equivalent under the operations of 21 noncentrosymmetric point groups are derived.
대구지역 금호강 및 주요 지천 퇴적물의 시·공간적 독성변화
정홍배,문성환,정진애,김재현,박정규,배철한,황인영 한국환경독성학회 2001 환경독성보건학회지 Vol.16 No.4
1. 사전에 선정된 공통 조사 정점들 가운데 KㆍH4(금호대교)이후의 퇴적물 독성이 상부의 것보다 크게 나타났다. 즉, 정점 KH3과 KH4, 그리고 KH4와 KH5 사이에 독성물질 유입원이 있는 것으로 판단되었다. 2. 하천 퇴적물의 독성 수준에 영향을 주고 있는 물질의 종류와 배출원 파악이 필요하였다. 이러한 내용을 향후 계속적 연구 및 조사를 통하여 수행되어야 하는 과제라 사료된다. 3. 퇴적물 시료의 채취 시점에 따라서 동일 정점의 독성 변화가 심하였다. 유해화학물질에 의한 오염 수준과 하천 생태계의 영향을 예측하기 위해서는 하천 퇴적물을 대상으로 경시적으로 독성의 변화를 계속 관측하는 것이 필요하다고 판단되었다. In aqueous ecosystems, the level of toxicity is highly responsive dependant to multiple variables, including rainfall, sunlight, pH, adhesion, etc. Because Korea has particularly distinct wet and dry seasons, the toxicity of pollutants in rivers or streams is dependant on the sampling season and time. In order to examine the effects of rainfall on toxicity, sediment samples were collected from five sites along the Keumho river. It was found that Microlox toxicity levels were generally higher during the dry season than the wet season. It indicated that river pollutants are carried off more quickly by the water during the wet season. As a result, it was recommended that the point sources of pollutants of the Keumho river would be placed between KH3 (Paldalgyo) and KH4 (Keumhogyo), KH4 (Keumhogyo) and KH5 (Dasa).

SbSI결정의 Piezoelectricity에 관한 연구
裵世煥,洪鎭泰 東亞大學校 1983 東亞論叢 Vol.21 No.3
The SbSI crystal were grown by the phase transportation method. Dielectric constant and D.C. conductivity were measured in the temperature range between 0℃ and 40℃. By measuring the resonance-antiresonance method, the piezoelectric modulus ??, electromechanical coupling factor ?? and elastic compliance coefficients ??, ?? have been determined in the temperature range between 5℃ and 22℃. The ?? has been found to show the highest value of ?? cgs esu near the Curie point. The ?? shows an extremely high value of 85% just below the Curie point. While ?? exhibits a pronounced anomaly below Curie point ??/dyne) is almost temperature independent.
