권오련,이정선,나은심,김훈 한국의료QA학회 2009 한국의료질향상학회지 Vol.15 No.1

문제: 소화기병검사실에서 대장내시경 검사의 부도건수가 최근 월 200명 정도로 예약인원의 16%에 달한다. 이는 본원 외래진료 부도율이 평균 10%인 것과 비교할 때 상당히 높은 결과이므로 대장내시경 예약환자를 대상으로 부도율 관리를 위한 활동이 필요하였다. 목적: 외래 및 입원환자의 부도건수 및 부도환자의 특성을 분석하고, 개선활동을 통하여 대장내시경 검사의 부도율을 줄인다. 의료기관: 서울 아산병원 질 향상 활동: 부도관리를 위한 개선활동으로 SMS 횟수를 2주전, 4일전, 1일전 3회로 변경하고, 내용도 각 시기마다 차별화하였다. 대장내시경 검사 예약을 하고 기다리는 환자를 대상으로 처방일 순, 예약 날짜순서 등 필요한 항목 순으로 볼 수 있는 리스트가 필요하여 예약대기 프로그램을 개발하였고, 처방일로부터 2주 이내 자동예약을 금지하였다.(7월 10일부터 시작) 예약대기명단에 있는 환자를 대상으로 전화로 예약 변경을 하여 2주 이내에는 예약의 빈자리가 없도록 하였다. 미리 부도를 예측하여 추가로 예약하던 방법에서 정원조정을 하여 정원 외 추가 예약을 하지 않았다. 입원환자 일정관리를 위하여 일정관리 프로그램을 개발하여 타과의뢰 회신을 하는 전임의가 직접 날짜를 전산에 입력하여 회신과 동시에 검사실, 담당주치의, 담당 간호사가 모두 일정을 확인할 수 있도록 하였으나 프로그램이 늦어져 9월 12일부터 시행하였다. 개선효과: 부도건수가 개선 전 8주 동안 385건(예약인원 대비 16%) 에서 개선 후 6주의 평가기간 동안 256건(예약인원대비 14.1%)으로 129건이 감소하였으며, 검사 1-2일전 일정 변경 연락 환자 감소 및 검사 비용 수납 환자의 부도건수가 감소하였다. 대장내시경 검사 예약대기 프로그램 운영 및 예약 변경 전화 활동으로 2달씩 기다리던 환자의 예약일을 약 한 달 정도 단축하여 줄 수 있었다. 검사 정원 관리의 결과로 검사 예약 시 예약기준이 명확해지고, 부적절한 예약으로 인한 검사지연 등이 확실히 줄었다. 또한 입원환자 일정관리 프로그램 적용으로 입원환자의 검사일정과 관련된 전화업무는 확실히 줄어들 것으로 예상된다.

This era is approached that the dynamic web server survives which is interacting with database. And also a lot of studies about minimizing the cost and properly updating softwares in time is carried out. COM(Component Object Model) is recently one of the software development methodology In many case, ODBC(Open Database Connectivity) drivers are used in web database design. But some problems cannot be solved by the ODBC. These problems can be solved by COM which is the concept of the component. We approached to the web database access using COM, In this paper we provide detailed interface modeling of web database. The interface modeling provided consists of COM Client. Web server, Com Server and can show the client the result of what he want to insert by SQL statements.

하우스 장미 切花裁培 技術確立에 관한 硏究 : Ⅰ. 新稍生長 및 開花에 대한 溫度 輔光處理 果와 組織培養 技術을 利用한 幼苗 生産 The Effect of Temperature and Supplemental Lighting on Shoot Growth and Flowering of Rose and the Seedling Production used Tissue Culture Technique

蘇寅燮,權五均,玄海男,康勳,張田益 濟州大學校 亞熱帶農業硏究所 1992 亞熱帶農業硏究 Vol.9 No.-

本 硏究는 濟州地域의 冬季 장미 切花裁培를 위한 技術開發의 側面에서 栽培的 品種選拔을 위하여 露地裁培에 대한 可能性을 檢定하며, 土壤과 비배관리를 위한 基礎資料와 組織培養技術을 利用한 優良苗生産技術을 確立하기 위하여 修行하였던바 얻어진 結果는 다음과 같다. 晝夜間의 溫度變化가 심한 環境下에서도 잘適應했던 品種은 'Innocencia'와 'Madelon'이었다. 화경장은 無加溫 비닐하우스가 加溫 유리온실보다 좋았으며, 切花量은 약간 적었지만 濟州道의 西歸浦 地域에서 장미의 冬季 生産을 위한 無加溫 비닐하우스 栽培도 可能한 것으로 나타났다. 加溫과 輔光處理는 開花日數를 10-15일 가량 앞당겼으며 花質과 採花量도 向上시켰지만, 經濟的인 側面에서 볼 때 비닐하우스 無加溫 栽培도 비교적 良好한 結果를 보였다. 共試品種中 無加溫 비닐하우스 輔光栽培에 適合한 轢으로는 'Lorena', 'Dallas', 'Golden Madelion', 그리고 'Carl-red'等 이었다. 장미재배 土壤의 物理性은 孔隙率이 크기 때문에 배수성과 통기성이 장미재배에 적절하였으며, 재배 기간동안 유리온실 토양의 pH, 置換性 Ca, Mg 및 K, 有效燐酸의 함량은 비닐과 露土 토양에 비하여 높게 유지되었다. 不定芽 發生에 대한 基本 배지로는 MS배지 보다 WPM배지가 共試된 品種 모두 월등한 結果를 보였다. 生長點 培養時 0.1-1.0mg/l의 NAA와 2.5-5.0mg/l의 BA 混用處理가 苗의 生産과 生體重 向上에 좋은 結果를 나타냈다. 幼苗의 發根과 根數, 根長 그리고 活着率 모두 1㎖/l IBA處理보다 活性炭 2g/l添加 處理에서 良好하였다. The purpose of this study is to extract useful information for selecting a suitable variety of cultivation for cut flowers of rose. To meet this purpose three different ways of cultivation, such as non-heated and heated cultivations in vinyl house, and outdoor cultivation, were tested in terms of developing cultivation technique for cut flowers of rose during winter period in Cheju island. In addition, the research attempts to obtain basic idea for soil and culture condition and to develop production technique for a superior plantlet by using the technique of tissue culture. After analyzing the results we have reached the following conclusions: 1. 'Inocenia' and 'Madelon' were the most adaptable varieties under the wide temperture changes during day and night. 2. For the flower stem length, the non-heated vinyl house was preferred to the heated glasshouse. 3. It was found that the non-heated vinyl house is possible during winter period in Seogwipo city area. 4. The treatments of heating and supplemental lighting allowed not only to push about 10 to 15 days ahead of the flowering time but also to improve the quality and the amount of flowers. In terms of the economy, however, the treatments of non-heating and supplemental lighting might be preferrable to the one just described. 5. Among the tested cultivars, 'Lorena', 'Madelon', 'Dallas', 'Golden Madelion' and 'Carl-red' were suitable for the cultivation of non-heating and supplemental lighting. 6. Physical properties of the soil in the treatments were suitable for house culture of cut-rose, and pH, available phosphorus, exchangeable Ca, Mg, and K and nitrate concentration of soil in glasshouse were higher than vinylhouse and open field. 7. The results from the test of basic media about the generation of adventitious rooting showed that the WPM medium is better than the MS medium for tested six cultivars. 8. It was identified that the application of 0.1-1.0 mg/l NAA and 2.5-5.0 mg/l BA at the time of meristem culture came out with likable outcomes for plantlet production and improvement of fresh weight. Treatment of 2 g/l activated charcoal is better than 1 mg/l IBA for rooting, root number, root length, and rooting percentage of a plantlet.

The purpose of this study is to determine whether movement strategies affect functional forward reach distance in a standing position. Forty-seven healthy subjects were selected for this study: 23 men and 24 women, with an average age of 22.3. Functional forward reach distances were measured as hip strategy and squat strategy(included knee and ankle movement strategy) in a standing position, respectively. The mean values of functional forward reach distance in hip strategy, squat strategy were 33.57㎝, 29.48㎝, respectively. There was significantly difference in functional forward reach distance between hip strategy and squat strategy(p<.001). There was no difference of functional forward reach distance between male and female in hip strategy, but there was significant difference in other strategy(p<.05). These results suggest that movement strategies should be considered during functional forward reach test in standing. Further study is required to determine whether movement strategies affect functional reach distance in elderly and disabled groups.

Low-viscosity composite resins may produce better sealed margins than stiffer compositions (KempScholte and Davidson, 1988; Crim, 1989). Flowable composites have been recommended for use in Class V cavities but it is also controversial because of its high rates of shrinkage. On the other hand, in the study comparing elastic moduli and leakage, the microfil had the least leakage (Rundle et al. 1997). Furthermore, in the 1996 survey of the Reality Editorial Team, microfills were the clear choice for abfraction lesions. The purpose of this study was to evaluate the microleakage of 6 composite resins (2 hybrids, 2 microfills, and 2 flowable composites) with and without load cycling. Notch-shaped Class V cavities were prepared on buccal surface of 180 extracted human upper premolars on cementum margin. The teeth were randomly divided into non-load cycling group (group 1) and load cycling group(group 2) of 90 teeth each. The experimental teeth of each group were randomly divided into 6 subgroups of 15 samples. All preparations were etched, and Single bond was applied. Preparations were restored with the following materials (n=15) : hybrid composite resin [Z250(3M Dental Products Inc. St.Paul, USA), Denfil(Vericom, Ahnyang, Korea)], microfil [Heliomolar RO(Vivadent, Schaan, Liechtenstein), Micronew(Bisco Inc. Schaumburg, IL, USA)], and flowable composite[AeliteFlo(Bisco Inc. Schaumburg, IL, USA), Revolution(Kerr Corp. Orange, CA, USA)]. Teeth of group 2 were subjected to occlusal load (100N for 50,000 cycles) using chewing simulator(MTS 858 Mini Bionix Ⅱ system, MTS Systems Corp., Minn, USA). All samples were coated with nail polish 1mm short of the restoration, placed in 2% methylene blue for 24 hours, and sectioned with a diamond wheel. Enamel and dentin/cementum margins were analyzed for microleakage on a sclale of 0 (no leakage) to 3 (3/3 of wall). Results were statistically analyzed by Kruskal-Wallis One way analysis, Mann-Whitney U-test, and Student-Newmann-Keuls method. (p=0.05) Results: 1. There was significantly less microleage in enamel margins than dentinal margins of all groups. (p<0.05) 2. There was no significant difference between six composite resin in enamel margin of group 1. 3. In dentin margin of group 1, flowable composite had more microleakage than others but not of significant differences. 4. There was no significant difference between six composite resin in enamel margin of group 2. 5. In dentin margin of group 2, the microleakage were R>A=H=M>D>Z. But there was no significant differences. 6. In enamel margins, load cycling did not affect the marginal microleakage in significant degree. 7. In dentin margins, load cycling did affect the marginal microleakage only in Revolution. (p<0.05)

Background : In recent years, gonorrhea has been panedemic and remains one of the most commom STDs in the world, especially in developing countries. Objective & Methods: For the detection of a more effective therapeutic regimen and assessing the prevalence of PPNG, we have been trying to study the patients who have visited the VD Clinic of Choong-Ku Public Health Center in Seoul since 1980 by means of the chromogenic cephalosporin method. Results: In 1996, 139 strains of N. gonorrhoeae were isolated, among which 53(39.0%) were PPNG. Conclusion: Our results suggests that after a peak of 74.3% in 1993, the prevalence of PPNG in Seoul is gradually declining.
