A pilot scale SBR (working volume, 20㎥) treating piggery wastewater was operated with real wastewater. The operation mode of intermittent feeding of raw water and sub-cycle with repeating anoxic-aeration conditions were adapted to avoid the high-strength nitrogen inhibition. In sub-cycle, aeration time for nitrification was tried to be controled with ORP and/or DO meter. The characteristics of control was somewhat different between ORP and DO. DO showed potential ability to detect complete ammonia oxidation point by the first order differential values or absolute value. Especially, DO was proved to be useful for high loading rates. ORP indicated the ending point of nitrification by the plateau appearing after bending point. Because ORP can be utilized as a diagnosis tool by its good sensitivity for the microbial condition in reactor, the simultaneous application of DO and ORP was recommended for the stable control of SBR.

This study was conducted in order to explore general flora of the Gyounggi-do Province and to clarify the distribution of some specificated taxa of the Korea. Daebu-do Island, Mt. Taewha, Mt. Hwaya, Mt. Gumdan, Mt. Chilhyun and Mt. Chulma among eighth grade-area of the Degree of Green Naturality (DGN) within the boundary of the Gyounggi-do Province were visited to investigate local flora. The number of identified vascular plant species were as follow; Mt. Hwaya: 120 species (99 genera of 67 families), Mt. Teawha: 132 species (103 genera of 56 families), Daebu-do Island: 124 species (103 genera of 50 families), Mt. Chulma: 129 species (99 genera of 67 families), Mt. Gumdan: 121 species (96 genera of 52 families), Mt. Chilyun: 90 species (74 genera of 42 families). The endemic Clematis brachyura Maxim. was found to distribute Daeby-do. It seemed that plantation was occupying large area in forest of the Gyounggi-do Province. Forty two specificated taxa were identified and 3 taxa, 10 taxa, 5 taxa, and 24 taxa were sorted into forth grade, third grade, second grade, and first grade respectively. Mt. Taewha showed the highest record (16 taxa) in the number of specificated taxa, Mt. Hwaya was the next with 13 taxa. Mt, Chulma (12 taxa), Mt. Gumdan (11 taxa), Daebu-do Island (7 taxi), and Mt, Chylma (4 taxi) followed. Mt. Taewa and Mt. Whaya were found to be relatively higher in the score calculated front the specificated taxa distribution, while Daebu-do Island and Mt. Chilyun were lower, that difference was probably due in part to consequences of severe disturbance of human activities. With respect to the consequences of severe disturbance of human activities. With respect to the geographical proximity to the Gangwon Province, Mt. Hwaya showed higher similarity of the species composition to that of the Mt. Jumbong.

도윤호,문태영,남상호 대전대학교 기초과학연구소 2002 自然科學 Vol.13 No.2

경상남도 양산시에서 반딧불이의 다양성과 분포를 조사하였다. 11개 지역에 3종이 확인되었는데, Hotaria papariensis (Doi) 파파리반딧불이가 4장소에서, Luciola lateralis Motschulsky 애반딧불이가 4장소에서, Lychnuris rufa (Olivier) 늦반딧불이가 4장소에서 기록되었다. 파파리반딧불이는 천성산, 금정산, 영축산등의 산기슭에서 관찰되었고 양산의 동남부 지역에 집괴분포하는 경향을 보였다. 애반딧불이는 천성산의 동측사면의 수답을 따라 선형분포를 보였다. 늦반딧불이는 산만한 분포를 보여 추후 자세한 조사가 필요할 것으로 생각된다. 이 3종의 반딧불이가 모두 분포하는 천성산 지역은 울산과 부산을 서로 연결할 수 있는 지리적 위치로 서식지 네트워크를 구축하면 반딧불이 집단 간에 유전자 교류가 가능할 것이다. It was investigated the dwersity and distribution of fireflies from Yangsan city. Hotaria papariensis (Doi), Luciola lateralis Motschdsky and Lychnuris rufa (Olivier) were observed respectively at 4 different spots, but 11 spots in total. H. papariemis was recorded at Mts. Cheonseong, Keumjeong and Yeongchuk, but was concentrated at the eastern part of Yangsan. L. lateralis was observed along waterlines crossing rice paddies. However L. rda was scatteredy found and should be investigated further for the factors regulating distribution. Mt. Cheonseong that all 3 species recorded is likely to act to support a biogeographical network to conserve the firefly-genepool in Busan, Ulsan and Yangsan.

행정정보화의 효율적 추진에 있어서 가장 기본적인 요건은 공무원의 정보기술활용능력의 향상이다. 이에 따라서, 지방자치단체들은 공무원의 전산화교육강화를 시정정보화사업의 핵심과제 중의 하나로 삼고 산하 전 공무원을 대상으로 정보화 사회/의 도래와 사무자동화에 따른 행정환경 변화에 능동적으로 대응하고, 정보화추진의 기반을 조성하기 위하여 다양한 정보화교육을 실시하고 있다. 본 연구는 대구광역시를 대상으로 정보화(전산)교육의 현황을 살펴보고 그 개선방안을 제시하였다. 분석결과, 대구광역시의 정보화(전산)교육은 추구하고자 하는 기대에 크게 못 미치는 것으로 나타났다. 정보화(전산)교육에 대한 만족도는 낮은 것으로 조사되었는데, 대부분의 조사대상자들은 원하는 시간에, 원하는 장소에서, 원하는 내용의 교육을 못하고 있는 것으로 나타났으며, 그리고 대체로 정보화(전산) 교육과정이 적절하지 않다고 평가함으로써 정보화교육의 개선 필요성을 보여주고 있다.

후두 및 하인두 편평세포암종에서 E-cadherin의 면역조직화학적 발현

도남용,나한조,이도용,허준,최지윤,이홍영,임성철 조선대학교 2000 The Medical Journal of Chosun University Vol.25 No.2

Background and Objectives : The cell-cell adhesion molecule E-cadherin is necessary for the maintenance of the epithelial cellular structure. We were designed to confirm the significance of E-cadherin as a marker for differentiation and invasiveness of squamous cell carcinoma of the larynx and hypopharynx. Materials and Methods : Our study was investigated for the immunohistochemical expression of the epithelium-specific cell adhesion molecule E-cadherin in formalin fixed paraffin embedded tissue specimen of 32 cases of squamous cell carcinoma of larynx and hypopharynx. Results : The positive expression of E-cadherin was 56.3%(18 cases) in squamous cell carcinoma of the larynx and hypopharynx. Decreased E-cadherin expression was a stastistically significant correlation with a increased grade of lymph node stage and clinical stage. Reduced expression was seen in the large tumor size and poorly differentiated tumors, but these result was not statistically significant. Conclusion : The expression of E-cadherin may be related with progression of squamous cell carcinoma of the larynx and hypopharynx. But these correlation were not sufficient for the prognostic indicators in squamous cell carcinomas of the larynx and hypopharynx.

Do Yeun Kim,Sang Min Lee,Kyoung Eun Lee,Hye Ran Lee,김지현,Keun-Wook Lee,Jong Seok Lee,Soon Nam Lee 대한암학회 2006 Cancer Research and Treatment Vol.38 No.4

Purpose: We wanted to analyze the use of nutrition support for terminal cancer patients, the effect of discussing withdrawal of nutrition support and do-not- resuscitate (DNR) consent on the use of intravenous nutrition during the patient’s last week of life and at the time of death.Materials and Methods: The study involved 362 patients with terminal cancer from four teaching hospitals, and they all died between January 1 2003 and December 31 2005. The basic demographic data, the use of intravenous nutrition during the patient’s last week of life and at death, discussion of terminal nutrition withdrawal and DNR consent were evaluated.Results:In the week before death, the patients received artificial nutrition such as total parenteral nutrition (31%), intravenous albumin infusion (25%), and feeding tube placements (9%). A discussion concerning withdrawal of nutrition support was limited to 25 (7%) patients. DNR consent was obtained from 294 (81%) patients. None of the patients were directly involved in any of these decisions. The discussion about withdrawal of terminal nutrition and DNR consent with the patient’s surrogates did not have any effect on reducing the use of parenteral nutrition.Conclusion: The majority of patients dying of terminal cancer were still given potentially futile nutritional support. Modern clinical guidelines and ethical education about nutritional support at the end of life care is urgently needed in Korean medical practice to provide proper administration of terminal nutrition for end of life care.

하악전돌증의 악교정수술 후 연조직 형태변화에 대한 연구

성상진,박현도,김재승,문윤식 대한치과교정학회 2000 대한치과교정학회지 Vol.30 No.3

악교정수술에 관한 치료계획은 치료결과에 관한 정확한 예측을 바탕으로 수립되는 것이 바람직하며 이는 심미적인 결과를 얻기 위한 가장 중요한 요소 중에 하나이다. 성인에서 골격성 하악전돌증의 치료는 하악골후퇴술을 이용한 악교정수술법이 주로 이용되는데, 술후 턱끝의 돌출도가 과도하게 감소되어 하악전진이부성형술을 추가로 시행해야 하는 경우 하악골과 턱 부위의 연조직 변화방향이 상이하게 나타나므로 술후 연조직 변화를 정확히 예측하는데 한계가 있다. 본 연구에서는 골격성 하악전돌증을 주소로 악교정수술을 시행한 성인을 대상으로, 상행지시상분할골절단술(BSSRO)만을 시행한 경우(A군) 11명과 하악전진이부성형술(advancement genioplasty)도 같이 시행한 경우(B군) 9명의 경조직과 연조직 변화의 상관관계를 알아보기 위하여, 수술 8개월 이후에 채득된 측모두부계측방사선사진을 비교하여 다음과 같은 결과를 얻었다. 1. E-line에 대하여 상순은 더 돌출되고 하순은 더 후퇴되어 입술의 형태가 개선되었으며,하악전진이부성형술을 병행한 경우 하순의 돌출도는 더 개선되었다. 2. 두 군 모두에서 상순은 후방이동하고 비순각은 증가하였다. 3. 술후 B점에 대한 연조직 POGs점의 변화율은 A군에서 84%, B군에서 66%로 나타났으며 두 군간에 통계적 유의성이 있었다. 4. 경조직과 계측점의 수직변화량은 A군에서 감소하였다. The treatment plan for orthognathic surgery must be based on accurate predictions, and this can be produced the most esthetic results. Treatment of prognathic mandible in adult is usually orthognathic surgery using mandible set back, but mandible with retruded chin point is needed additional chin augmentation. In this case, the directions between mandible and chin point are different therefore, the prediction of soft tissue reactions must be modified. In this study, we materialize the patients who was taken orthognathic surgery due to prognathic mandible, 11each(Group A) was taken only Bilateral Sagittal Sprit Ramus Osteotomy (BSSRO), 9each(Group B) was taken additional advancement genioplasty. The lateral cephalometric radiography taken 8 months later after orthognathic surgery by this patients were used. The results of this study were as follows : 1.The profile of lips was favorable after surgery due to upper lip to E-line became prominent and lower lip to E-line was retruded. 2.In both group, upper lip moved posteriorly and nasolabial angle was increased. 3.The ratio of the soft tissue profile change in POGs point to skeletal B point movement was 84% in group A and 66% in group B, and there was statistical significance between group A and group B. 4.Vertical movement of hard tissue points is decreased in group A.
