In this paper, we analyze customers' working electric energy (kWh) which is served pole-transformer in order to reduce peak load current error which is generated in application load correlation equation. The characteristic of electric load which customers are using is classified by customer's working electric energy (kWh) and ratio of cooling equipment possession. For the input data of fuzzy model, we used to kWh on April which represents basic load and kWh which is increased from April to August. The April kWh is used to classify into large, medium, small customer. Also, the increased kWh is used to know information of cooling equipment possession. For the output value of fuzzy model, we can determined peak load current limit in application load correlation equation.

Dr. Chul Han Kim. 1999. Historical Background of Bible Studies and Typical Analysis of Bible Teaching Materials. Collected Papers on Christian Language Culture. Bible studies can be found to have played an important role in recognizing the God's plan and guidance toward man and taking a living attitude according to the will of God for man in Jesus Christ. And this paper is to analyze the historical process of Christian education through inquiring into historical background of Bible studies on the basis of periodic typical analysis of Bible teaching materials.

Dynamics in the workplace and in society have contributed to the paradigm shift to outcome-based education. This study was performed to develop the curriculum based on assessment of existing program for the baccalaureate nursing program at Cheongju University. We used three steps-Analysis, Design, and Development-in ADDIE model for developing curriculum. The subjects were 18 graduate nurses, 41 nursing students, 38 parents, and 2 nursing team leaders for analysis of core competence. In conclusion, developing an outcome-based curriculum might be used to facilitate the students' development and evaluate the competence of the student during and on completion of the nursing baccalaureate program at Cheongju University.

미생물응집제를 개발하기 위하여 자연계로부터 방선균 600여 균주와 보관균주를 대상으로 응집활성이 우수한 균주를 선별하고 동정한 결과 corynebacteium 속으로 동정되었다. 응집제 생산을 위한 최적조건은 2% glycerol, 0.4% peptone, 0.1% yeast extract, 0.3% K_2HPO_4, 0.1% CaCO_3, 0.05% NaCl, 0.1% MgSO_4·7H_2O, pH 7.5의 배지 100 ml을 500ml baffle flask에 넣고 96시간 회전진탕배양할 때였으며 상기의 조건으로 jar fermentor 배양시 96시간에서 780 units/ml의 응집활성을 나타내었다. 응집물질은 pronase 처리와 periodate 산화에 의해 각각 무처리구와 13%와 106%의 활성을 나타냄으로써 응집활성은 주로 단백질에 기이함을 알 수 있다. About 600 microorganisms isolated form soil, marsh, compost, etc. were examined for their flocculating ability in the kaolin suspension and swine wastewater. Among them, K-199 was the best producer of flocculant and was identified to be a species belong to the genus corynebacteium. The maximum production of the flocculant from Corynebacterium sp. K-199 was observed in culture medium containing 2% glycerol, 0.4% peptone, 0.3% K_2HPO_4, 0.1% CaCO_3, 0.05% NaCl, 0.1% yeast extract, 0.1% MgSO_4·7H_2O and initial pH 7.5 when cultured with rotary shaker controlled at 25℃ and 150 rpm. Under the optimal culture condition with jar fermentor, the maximum production was reached to flocculating activity of 780 units/ml after 4 days. From the results of the activity be fully maintained by periodate oxidization, it suggests that the activity is due to the protein.

Purpose: We determined the use of scrotal ultrasonography in the initial diagnosis and management of testicular injuries due to blunt scrotal trauma. Mateiials and Methods: We reviewed 54 patients of scrotal trauma in the last 8 years. Forty patients were evaluated by ultrasonography preoperatively. A heterogeneous echo pattern of the testicular parenchyma with loss of oval shape, contour definition was the basis for diagnosis of testicular rupture. Among them, 33 cases underwent scrotal exploration and 7 cases were managed conservatively. The remaining 14 patients were evaluated only by physical examination, 8 patients of them were explored immediately because of suspicious testicular mpture. The accuracy of ultrasonography were determined by comparing radiographic interpretations with intraoperative findings. Results: Among the 33 patients who were evaluated by ultrasonography and explored immediately, there were 26 suspected testicular ruptures on ultrasonography. Surgical exploration revealed testicular rupture in 23 and simple hematoma in 10. The testicular rupture was correctly diagnosed by ultrasonography in the 22 cases, and there were 4 false-positive and 1 false-negative diagnoses of testicular rupture. The sensivity and specificity for the diagnosis of testicular rupture are 96% and 60%, and the positive and negative predictive values are 85% and 86%, respectively, Conclusions: Scrotal ultrasonography, with the main radiographic finding of a heterogeneous echo pattern of the testicular parenchyma with loss of oval shape, contour definition, is highly sensitive on the diagnosis of testicular rupture. And it increases the salvage rate for testicular rupture with preservation of the testicular function and prevents delayed complications of chronic pain, atrophy and orchiectomy associated with missed testicular rupture.

The question of how skin coverage affects contracting wounds has long been a significant problem in the study of wound contraction. Myofibroblasts appear to be well established as the cellular cause of wound contraction. Myofibroblasts are found in many types of contracting wounds, including granulating wounds and hypertrophic burn scars. Myofibroblasts in contracting wounds have definitive life cycles, being present when contraction is active and then disappearing when contraction has ceased. In this study, we observated comparatively quantitative changes in the surface area by planimetry and changes of myofibroblasts by electron microscope through 8 weeks according to the types of skin coverage. The purpose of this study was to evaluate the myofibroblast population in skin coveraged wounds in a rat model, which allowed frequent biopsies as well as precise identificaion of the interface of the skin coverage and the wound bed. The results of our experiments are as follows: 1. Granulating wound Contracted rapidly and had long persistence of myofibroblasts. 2. Split-thickness skin graft Contrated less and myofibroblasts were more rapidly decreased and were disappeared at 5 weeks later. 3. Full-thickness skin graft Minimum contracti aondnmyofibroblasts were very rapidly decreased and were disappeared at 4 weeks later. 4. Local flap No contraction and could not find myofibroblast. Slowly increase in size at begining. 5. Contraction was influenced by number and lasting time of myofibroblast.

Background: Influenza transmission in households a subject of renewed interest especially in pandemic situation. We performed this study to investigate the laboratory-confirmatory rate in household contacts with index cases of pandemic influenza (H1N1 2009). Materials and Methods: For three months from 1 September and 29 November 2009, people who had a history of close contact with confirmed cases of pandemic influenza (index case) were recruited. The information on the study participants was collected using a standardized questionnaire. Presence of the pandemic influenza (H1N1 2009) infection was confirmed by real-time reversetranscription polymerase chain reaction (RT-PCR). Results: A total of 113 index cases and 141 household contacts were investigated. One hundred and four index cases (92.0%) were younger than 20 years. The median age of household contacts was 40 years. Twenty eight household contacts (19.8%) had acute respiratory illness (ARI). Overall, 10.6% of enrolled household contacts were positive in RT-PCR for pandemic influenza (H1N1 2009). The positive rate of household contacts with ARI was 25.0% and it was 7.1% in household contacts without ARI. The positive rate was significantly higher in children and young adults under 30 years (28.3%) compared with that in household contacts older than 30 years (8.3%). Conclusions: This results showed a significant role of mild symptomatic or asymptomatic pandemic influenza (H1N1 2009) patients as a virus carriers in households.
