지방정부 민원행정서비스 평가의 의의와 측정모형

서휘석,이동기 全北行政學會 2003 全北行政學報 Vol.17 No.1

고객지향적인 개념의 행정 접근은 이제 중요한 항목으로 받아들이고 있다. 특히 지방자치제가 도입된 이후 그 정도나 내용은 더욱 크게 주목받고 있다. 그 중 민원서비스 부문에 대한 관심은 지방정부의 민원프로그램의 개발과 운영, 서비스 접목 등에 집중되고 있다. 이러한 현상은 지방정부의 근본적인 형태가 지역주민에 바탕을 두고 있으며 이를 통하여 행정의 변화를 이끌어 내기 위한 노력을 하고 있다는 것을 확인할 수 있다. 민원행정서비스의 질과 그 제공 절차에 대한 시민의 인식은 정책의 지속성 유지뿐만 아니라 수혜자인 시민의 삶의 질에 결정적인 영향을 미친다고 보았을 때 그 중요성은 더욱 크다고 볼 수 있다. 따라서 본 연구는 지방정부의 민원행정서비스에 대한 평가의 의의와 측정모형에 대한 초점을 둔다. 민원행정서비스에 대한 평가모델은 시민들과의 직접적인 관계를 형성할 뿐만 아니라 행정의 변화를 느끼게 하는 중요한 창구이고 의사소통의 채널이기 때문이다.

서동석,이종국,이은구 조선대학교 생산기술연구소 1999 生産技術硏究 Vol.21 No.2

TiO₂ powders were prepared via the sol-gel method using titanium alkoxide. The process for the preparation of TiO₂ powder was studied as a functuion of the molar ratio of water to alkoxide. Microstructure, crystallization behaviour with heat treatment temperature, specific surface area, and particle size were examined using SEM. X-ray diffraction. TG/DSC, BET, and particle size analyser, respectively. The TiO₂ powders showed slightly agglomeration less than 0.5㎛ and the powders transformed amorphous to anatase phase at 450℃.

EDAP LT-01+ 체외충격파쇄석기를 이용한 요로결석 치험 1,816례 : A Report of 1,816 Cases

최동규,서기석,임정식 圓光大學校 醫科學硏究所 1995 圓光醫科學 Vol.11 No.2

Between February 8. 1990 and December 31. 1994, 1.816 renal units in 1.611 patients with urinary stones were treated with extracorporeal shock wave lithotripsy(ESWL) using the EDAP LT-01+ lithotriptor. The patients' mean age was 44.3 years with the range of 16 months to 92 years. Sex ratio was 1.39:1 with 936(58.2%) male and 675(41.8%) female patients. Locations of the stones were kidney in 746(41.1%) including 39 cases of staghorn calculi, ureter in 1061(58.4%) and bladder in 9 cases(0.5%). And mean diameter of the stones was 13mm ranging from 2mm to 80mm. Average number of treatments, average treatment time per session and average total storage per patient were 4.0 sessions, 37.6 minutes and 134.4. respectively. Of the 1,816 cases. 141 cases(7.8%) complained of severe pain requiring intravenous or intramuscular analgesics. Success rates by stone size were 98.0%(1,069 cases/1,091 cases, storage/treatment number: 74.7/2.7) in less than 10㎜, 94.4%(453 cases/480 cases, 146.1/4.5) in 10㎜ to 19㎜. 73.4%(116 cases/158 cases, 242.4/7.1) in 20㎜ to 29㎜ and 60.9%(53 cases/87 cases. 402.6/11.2) in more than 30㎜. Success rates by stone location were 66.7%(6/9) in bladder stones. 66.7%(26/39) in staghorn calculi. 77.9%(60/77) in ureteropelvic junction(UPJ) stones. 93.1%(658/707) in renal stones, 94.8%(458/483) in upper ureteral stones and 96.4%(483/501) in lower ureteral stones. Success rate(when patients having stone particles less than 4mm in diameter without causing urinary tract obstrution, were considered to be treated successfully) was 93.l%( 1,691/1,816) and stone-free rates was 88.9% (1,615/1.816). Additional measures used were double-J stenting in 91 cases, percutaneous nephrostomy in 42 cases and push-up in 39 cases. Post-ESWL complications were persistent gross hematuria lasting more than three days in 29 cases, high fever(>38℃) in 38 cases and steinstrasse in 109 cases. We conclude that extracorporeal shock wave lithotripsy with EDAP LT-01 + lithotriptor is an effective treatment modality for urinary stone less than 2.0㎝ in diameter even though retreatment rate is high.

수리계획기법을 이용한 효율적 물배분 시스템모델 : 서남부지역을 중심으로

한동욱,서종석 전남대학교 농업과학기술연구소 2000 農業科學技術硏究 Vol.35 No.-

In this study, mathematical programming was applied to solve for optimal water allocation in the south-western part of Korea, where water supply and demand are unbalanced. The water allocation system was developed to meet water balance in the region through water transfer between the Keum and the Young-San Rivers. The result of the study shows that water transfer may satisfy various water demands in the region until the year 2011 without building reservoirs.

이석민,선우재근,장경택,서수형,김민관,배동한 순천향의학연구소 1996 Journal of Soonchunhyang Medical Science Vol.2 No.2

Pap smear were performed to 30,294 women living in the north-west of Chung-nam. The result are summarized below 1. Positive vaginal cytology was 1.09 percent. 2. 72 percents women in their 30's and 40's experienced vaginal cytology. 3. Vaginal cytology was performed at a decreasing rate as age increases. 4. Positive cytology rate is 2.42% higher than average for elderly women over the age of 65. The present date indicates that pap smear is being widely recognized to be important but they needs to be continued advocacy for pap smear.

강인석,곽중민,박서영,이동희,김창학 경상대학교 생산기술연구소 2001 工學硏究院論文集 Vol.1 No.-

The current trend of If (Information Technology) in 21st century demands management innovation, that is Business Process Reengineering (BPR) in all the industry including construction project. The solution of its demand is proposed by IT based on Internet. And also, in order to meet this objective, from 1997 domestic construction industry is accelerating to systematize CALS (Continuous Acquisition and Life-cycle Support) which is being planned to apply by government. These efforts give much weight to build computer systems rather than to improve and redesign construction business process that is more important for system application. This research develops a model for applying the BPR to construction industry, especially construction site that is a base to build a system for CALS. And the research suggests performing method, process and modeling technique of BPR to be applicable in business process redesign of construction field. Also, focusing on the research of execution step of business in construction site will be helpful for the site worker to perform BPR in construction site.

While clustered VOD (Video On Demand) servers that have been proposed for building large-scale VOD system recently, have the advantages of high availability and scalability, the system level reliability of the clustered VOD servers could be decreased by adding more servers to scale up the capacity of the server. To alleviate this reliability problem and support server-level fault tolerance, this paper proposes and analyzes self recovery system based on RAID-3 and 4 with pipelining concept. The proposed self recovery system could increase the efficiency of the disk by accessing the disk with large size block as in RAID-4. The network resource could be used efficiently and the workload of memory could be decreased by sending data in small size block as in RAID-3. By introducing pipeline concept, the recovery tasks are processed at several nodes in parallel so that the workload in CPU, network, and memory could be distributed to several nodes.
