本 實驗은 施設園藝地帶인 光山郡, 順天市, 康津郡 等에서 葉菜類와 果菜類의 育苗用 床土를 試料로 22点 分讓받아 수행하였으며 結果는 다음과 같다. 1.床土의 助成과 性質에 關與하는 가장 重要한 因子는 有機物含量인데 有機物含量이 높아짐에 따라 假比重과 眞比重은 낮았고 空隙率, 水分含量, 全窒素, 置換容量은 높아진다. 2. 葉菜類의 床土는 有機物含量이 많은 반면 果菜類床土의 경우는 그보다 낮게 나타났다. 봄결구배추床土의 有機物含量은 8.85~9.19%의 範圍로 別變化가 없었다. 3. 床土의 pH는 4.9~7.2의 範圍에 있었으며 大部分이 pH 7±1로서 中性에 가까웠다. 4. 置換性 K는 7点이 1.0m.e. 以上이었고 15点이 1.0m.e. 以下로 나타났다. 5. 苗의 바람직한 生育을 위해 P.K.의 量을 規定짓기는 어려우나 床土의 試料內에는 相當量의 養分이 含有되 있는 것을 알 수 있다. This experiment was intended to know the effects of physical and chemical properties of the excellent composts. Twenty two samples were collected from plastic covered greenhouse zone in chonnam province. The results obtained are as follows; 1. One of the most important factors in relation to the texture and other properties of the composts was the organic matter content. The higher the organic matter content were the lower the specific gravity and the apparent specific gravity and the higher the porosity, moisture content, total nitrogen and exchangeable capacity. 2. The composts for raising leaf vegetable seedlings contained higher levels of organic matter while the ones for fruit vegetable contained rather less. The organic matter contents in the composts for spring heading Chinese cabbage were not variable ranging from 8.85 to 9.19 percent. 3. Hydrogen-ion concentrations of the composts were in the range of pH 4.9~7.2 but most of them were in pH 7±1 or nearly neutral in their reaction. 4. Seven samples contained more than l.0m.e. of exchangeable potassium, and fifteen of them contained lower than l.0m.e. of it. 5. It was not clear how high of P or K levels were sufficient for the excellents in some of the samples, at least, were so high, that they seemed to contain surplus amounts of fertilizers.

The acoustical properties of the chamber at the Department of Physics, Sung Kyun Kwan University are investigated. By using the least square method based on pressure inverse law each reference sound pressure level is determined. The free field data are collected at both outdoor and indoor measurements. The deviations from the free field condition show that a reference sound pressure level plays a critical role in evaluating the performance of anechoic chamber. The cutoff frequency of the anechoic chamber is found to be in the range of 150Hz-170Hz.

설악산 국립공원지역 산간계류의 17개 지점에서 2000년 6월부터 2001년 6월까지 어류상 및 이화학적 요인을 계절별로 총 4회에 걸쳐 분석하였다. 모든 조사지점은 1~3차의 하천으로 비교적 물리·화학적 교란이 적었으며 하천폭은 5~30 m 정도였다. 채집된 어류는 총 18과 42종 2,557개체였고, Cyprinidae는 16종으로 84.7%의 상대풍부도를 나타냈으며, Gobiidae 4종, 5.0?의 상대풍부도를 보였다. Cyprinidae는 전체 채입종의 37.2%를 나타냈다. 우점종은 Zacco temminck로 10개 지점에서 738개체가 채집되어 28.9%의 상대풍부도를 나타냈으며, 아우점종은 Rhynchocypris kumkangensis와 Z. platypus로 각각 4개 지점 648개체(25.3%)와 7개 지점 344개체(13.5%)로 나타났다. 한국고유종(Korean endemic species)은 모두 4과 11종 781개체로 30.5%의 상대풍부도를 나타냈으며, 고유화 빈도는 25.6%로 한국의 평균 고유화 빈도와 유사하게 나타났다. 본 조사에서 외래어는 채집되지 않았다. 국립공원 내에 서식하는 어류의 다양성 유지와 회복을 위해서는 공원 내는 물론 경계지역 하천의 체계적인 관리가 요구된다. The fish fauna of mountain streams in the Seorak National Park area was investigated from June 2000 to June 2001 (4 times). All 17 sites were relatively undisturbed 1st to 3rd order streams. A total of 2,557 individuals were collected and classified into 17 families and 43 species. Cyprinidae accounted for 37.2% (16 species) of the total fish species and 84.7% (2,165 ind.) of the total abundance. Subdominant families were Gobiidae (4 species, 5.0%) and Balitoridae (3 species, 3.4%). Zacco temmincki (RA 28.9%, 10 sites) dominated. Subdominant species were Rhynchocypris kumkangensis (25.3%, 4 sites) and Zacco platypus (13.5%, 7 sites). Eleven of the species are endemic to Korea (4 families, 30.5%). Exotic species were not collected in this survey. Fish diversity was higher in streams around the boundary area than in the national park. Therefore, management of streams in the boundary area to protect the fish biodiversity can be efficiently conducted. Habitat degradation should be reduced for the conservation and restoration of fish diversity.

Background: We have doubt about the truth that Type 2 DM is associated with chronic hepatitis C infection. The aim of our study was to prove a close relationship between chronic HCV infection and type 2 DM in korean patients. Methods: We reviewed the out-patient's medical records of 466 patients with type 2 DM who visit the Sung-ae hospital from March 2000 to August 2001. Diabetic patients were analyzed for the following variables: age, sex, waist circumference, weight, waist/hip ratio, using of self monitoring of blood glucose, method of therapy, duration of disease, experience of previous transfusion, major surgical procedure, accompanied disease, liver function tests (LFT), HbA1 c. We ruled out patients with liver cirrhosis. Results: Hepatitis C virus infection was observed more frequently in patient with Type 2 DM. Of 466 Type 2 DM patients, 13 patients were infected with Hepatitis C virus (2.79%). Compared with mean prevalence of Korean population (1.3~1.6%), it's value is very high. the other hand, 21 patients were infected with Hepatitis B virus (4.5%). Such results are similar to mean prevalence of the general public (4~5%). Conclusions: Prevalence of hepatitis C was closely associated in korean patients with type 2 DM. And an increased prevalence is independent of cirrhosis.

Half space problems of structural system, which are usually solved using simple truncation of far field or using analytical far field solution, are considered using infinite elements. Among the infinite elements previously developed, a mapped infinite element is adopted and implemented in a finite element code which can handle two dimensional problems. Implemented program is applied to a cavity problem subject to internal pressure. The resulting solutions are compared with boundary element solutions due to Brebbia. In addition, conventional finite element analyses with simple truncation are carried out to compare the efficiency and accuracy of the developed program. The results show that the developed program renders accurate solutions which are close to the known values. Also, it can be seen that the developed program requires a smaller number of elements, so as shorter computing time than the conventional finite element codes, to get the same degree of accuracy.

간헐적 교정력 적용 후 백서 치주인대에서 UNC-50 유전자의 발현

박미경,박주철,임성훈,김광원 대한치과교정학회 2006 대한치과교정학회지 Vol.36 No.4

기계적 응력은 정상적인 발달과정 동안 조직의 항상성에 있어 중요한 역할을 한다. 기계적 응력은 치아 이동과 저작과 같은 상황을 포함한다. 치아 이동과 저작 중에 치주인대 섬유모세포는 기계적 자극을 감지하고 주위의 세포밖 물질과 생체분자 대사의 변동에 의해 반응을 보인다. 그러나 아직까지 기계적 응력 하에서 치주인대 세포에서 발현된 유전자에 관한 연구는 미비한 실정이다. 최근 기계적 응력이 초파리에 존재하는 UNC-50 유전자에 영향을 줄 수 있다고 보고되었다. 또한 UNC-50은 치은 섬유모세포와 비교해 치주인대 섬유모세포에서만 발현된다고 보고되었다. 본 연구에서는 간헐적 교정력 적용 시에 백서의 치아에서 일어나는 치근 및 치주 조직의 조직학적 변화와, UNC-50의 발현 양상을 면역조직학적 염색으로 조사하여 치주인대에서 기계적 응력과 UNC-50의 관련성을 알아보고자 하였다. Sprague-Dawely계 수컷 백서 12마리를 4마리씩 세 군으로 나누어 상악 우측 구치부에 NiTi closed coil spring을 사용하여 40 g 정도의 견인력이 발생하도록 하여 하루에 1시간씩 간헐적인 교정력을 적용한 후 1, 3, 5일 후 치주인대의 조직학적 변화를 관찰하여 다음과 같은 결과를 얻었다. 조직학적 소견에서 상악 제1대구치 근심구개치근의 치근부 1/3에서 압박측은 안장측보다 더 좁은 치주인대공간을 보였고 교정력을 적용시킨 후 3일 후부터 인장측에서 백악모세포 활성으로 인한 백악질 침착이 관찰되었다. UNC-50은 인장측의 분화 중인 백악모세포에서 강한 발현을 보였다. Osteocalcin은 인장측에서 압박측에 비해 신생 백악질에 존재하는 분화 중인 백악모세포를 따라 강한 발현을 보였다. 이상의 연구결과는 UNC-50이 간헐적 교정력 즉 기계적 응력의 변화에 따른 백악모세포의 분화과정에 중요한 역할을 함을 나타낸다. 그러나 이를 명확히 하기 위해서는 교정력 적용 후 UNC-50의 세포내 신호전달과정에 대한 보완연구가 필요할 것이다. Objective: Periodontal ligament fibroblasts have an ectomesenchymal origin and are thought to play a crucial role for not only homeostasis of periodontal tissues but also bone remodeling, wound healing and regeneration of tissues. Recently, it has been reported that UNC-50 is not expressed in gingival fibroblasts but in PDL fibroblasts. The purpose of this study was to examine the expression of UNC-50 and osteocalcin in the periodontium after application of intermittent force. Methods: Twelve rats had 40 grams of mesially-directed force applied at the upper molar for 1 hour/day. Four rats were sacrificed at 1, 3 and 5 days. Immunohistochemical localization of UNC-50 and osteocalcin antibody was carried out. The results showed apposition of new cellular cementum and a slight increase in periodontal space at the tension side. Results: Strong UNC-50 expression was observed in the differentiating cementoblasts close to PDL fibroblasts in the tension side whereas it was barely expressed at the compression side. Expression was strong at day 3, and decreased at day 5. Osteocalcin immunoreactivity expression was strong in differentiating cementoblasts at the tension side. Conclusion: It can be suggested that UNC-50 is related to the differentiation of cementoblasts, and may be responsible for the molecular event in PDL cells under mechanical stress.
