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.

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.

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.

This study aims to develop using a continuous removal of organic and settling solid(CROSS) to increase the efficiency of aeration system for wastewater treatment. To solve many problems of the conventional activated-sludge process, authors suggested a new CROSS model in conjunction with aeration systems in 1996. This system is characterized by utilizing an intensive aeration pipe with inlets at the lower portion and outlets at the higher portion in an aeration tank. Through the experiments on CROSS process, the average removal efficiences of BOD, COD_(Mn), SS, T-N and T-P were showed 98.8%, 93.9%, 98.0%, 71.3% and 49.8%. The average DO (Dissolved-Oxygen) concentration was constantly maintained at 8.0 mg/L by the intensive aeration which was accompanied by rapid reduction of BOD. Degradation of the organic matters in sewage then continued for the whole aeration period. The process demonstrated that it was very adaptive without seeding and returning the sludge. Compared to the activated sludge system, the system was very flexible for the continuous flow treatment. This preliminary assessment showed that the porous media in CROSS reactor is viable for the sewage treatment, since the porous media under the intensive aeration achieves acceptable effluent quality.
