The purpose of this study is to find out the relationship between Kiesler's Correalism and Digital Architecture, and the essence of the Digital Architecture, by comparing the spatial concept of Frederick J. Kiesler, who was active between 1920's and 1960's, with that of Greg Lynn, who is a digital architect. How Kiesler, who was contemporary with Le Corbusier, had tried to approach architecturally in a way other than the functionalism of Modernism, and how it is interlinked with the way the digital architects of today designs is analyzed in this thesis. Kiesler's Concepts - Correalism, Endless House, Biotechnique, and Galaxy - is analyzed, and compared with the Concept of Greg Lynn's space.

Background: Korean Hospital Standardization Program(KHSP), as a hospital accreditation program initiated and promoted by Korean Hospital Association since 1981, has played a key role in the hospital quality improvement in structural aspect particularly. Recently, however, KHSP has been critisized by hospitals and health personnels in that it is unpractical to be utilized as an initiative to improve hospital quality. In particular, the section of quality assurance in KHSP, strongly influenced by old version of Hospital accreditation of Joint Commission in U.S.A., has been required to be fundamentally sevised. For design of new criteria in quality assurance section, a survey for evaluation of existing program and collection of opinions for ideal one was conducted. Methods: For a month in 1994, structured questionnaires were administered by mailing to 470 hospital staffs from 200 hospitals, participated in the survey for the 1994 KHSP in each hospital. The total number of respondents was 116. Results: Less than half of the respondents(34.5%) value positively on the impact of current KHSP in general on the quality improvement of their hospitals. Moreover, most responses indicated that KHSP should be reorganized towards more practical and applicable one. Current KHSP criteria for quality activities in hospitals were regarded as a unpractical one which should be basically renewed. For new criteria and standards, most respondents emphasized the importance of applicability of those in real siuations. Conclusion: For the KHSP to be effective, new evaluation criteria for quality activities should be more practical and fully accommodated to hospital situations in reality.

'계획에 없던 재수술'의 분석

김은경,조성현,김창엽,오병희 한국의료QA학회 1995 한국의료질향상학회지 Vol.2 No.1

Background: clinical indicators are objective measures of process or outcome of patient care in quantitative terms. This study aims to review the medical records of patients who 'return to operating room during the same admission', which is one of the critical clinical outcomes, and describe the result by unplanned reoperation rate. Methods: Computerized patient registry was used for selecting subject conditions. For medical records retrieved, two nurse evaluators identified the presence of explicit reoperation planning in medical records. Results: Overall reoperation rate was 2.8% and unplanned reoperation rate 1.3%, The main category of reoperation cause was the postoperative bleeding. Duration of stay from previous operation to reoperation of the unplanned group, 12.7 days, was shorter than that of the planned(p<.05). The differences did not reach statistical significance in age, sex and length of stay. Conclusion: Results suggested that unplanned reoperation rate was lower than 'threshold' level other institutions had established. However, this result could become comparable only after management of medical records would be improved and risk adjusted.

한상엽,김행숙,박태수 大韓神經精神醫學會 1971 신경정신의학 Vol.10 No.2

This study was primarily designed to examine the probable difference, if any, of c causing factor to suicide among those who had previously attempted to commit suicide and initially attempted to commit suicide. The subjects were those who attempted to commit suicide and brought to the Suicide Prevention Center, Catholic Medical Center during the period from November 1, 1969 to December 31, 1971. Number of the subjects studied was 55 cases of re-attempted suicide and 159 case of once-attempted suicide in the period. The subjects represent the number which were thought to have met sufficiently the designed criteria for this particular study in terms fo cooperation, length of stay in the hospital and degree of reliability. The subjects were interviewed by the authors by the means of general psychiatric interview technique along with questionnaire card that had already been prepared for the purpose. Followings were the main results of the study: (1) Age distribution relatively that it was heavily concentrated to the ages of adolescent & old age group. (2) Sex distribution revealed no significant difference on the re-attempted suicide and once-attempted suicide. (3) The majority of the re-attempted suicides were tentatively diagnosed as schiazophrenia (23.63%) & personality disorder (20.0%). (4) The direct motives for the re-attempted cases were that of psychological problems such as mentai diseases, frustrated love relationship, inferiority, family discord & financial crisis et al. (5) Of the total number of 55 cases of re-attempted suicides, 10.9% of the interviewees accepted the need for further psychiatric treatment despite the fact that the physicians explained them the need of further care by every possible means. 76.36% had frankly denied the needs.

KOSPI 200 주가지수선물시장에서의 차의거래에 관한 실증연구

유상엽,김재만 한국산학경영학회 2003 산학경영연구 Vol.16 No.-

본 논문은 KOSPI 200 주가지수선물시장을 대상으로 1996년 5월 3일이후, 2000년 12월 14일까지 1,262일간의 근월물 월별 Data를 이용하여 시장도입초기의 실제가격의 이론가격에 대한 저평가 여부를 파악해보고, 이러한 실제가격과 이론가격간의 괴리로 인한 차익거래 기회의 존재를 거래비용을 고려하여 확인해 본 후, KOSPI 200 주가지수선물에서의 이론가격과 실제가격과의 괴리와 KOSPI 200 현물지수의 변동성과의 관계를 거래비용을 고려하여 파악해 보았다. 연구결과, KOSPI 200 주가지수선물은 이론가격에 비해 지속적으로 저평가 되어 있었다. 또한 개인 투자자의 입장에서 차익거래기회의 존재를 확인한 결과, 이론가격과 실제가격은 지속적인 괴리 현상으로 인해 매도·매수 차익거래기회가 존재하였고, 거래비용을 고려한 경우에도 차익거래기회가 존재하였다. 또한 선물시장에서 괴리가 발생한 날과 그렇지 않은 날로 구분하여, KOSPI 200 현물지수의 변동성을 검증해 본 결과 괴리가 발생한 날의 변동성이 보다 더 크다는 결론을 얻었다. This study is mainly aimed at analyzing the influence of the divergency(mispricing) between KOSPI 200 theoretical prices and its real prices of KOSPI 200 spot index, considering the existence of arbitrage opportunity from the mispricing. The data in this study are the daily prices of 1262 days, from 3 May 1996 to 14 December 2000. The results of our empirical study represent that the real prices in KOSPI 200 Stock Index Futures are continuously undervalued relative to their corresponding theoretical prices. Our study reconfirms the results from previous studies conducted at the domestic and overseas markets. We conclude that the undervaluation, especially in the market opening period, could come from fear of investors, whose experiences in the stock index futures market are limited, chiefly because of loss and uncertainty of prediction toward interest rates and dividends. Our study also represents that KOSPI 200 index shows more volatilities during days with mispricing relative to days without mispricing.

정신증상을 수반한 급성 간헐성 폴피리아의 1예 보고

한상엽,오민웅,김헌석,최수호 大韓神經精神醫學會 1972 신경정신의학 Vol.11 No.2

This is a brief report on a case Acute Intermittent Porphyria observed in the St. Mary's Hospital, Catholic Medical College, Seoul, Korea. The case was originally admitted to the internal medicine department where initial diagnostic workup was made. The case, however, showed various psychoneurotic signs which impressed both internists as well a psychiatrists who saw the case upon consultation that the patient might as well be suffered from hysteria. Consequently the Patient was transfered to the psychiatric free-ward where further observation, family study as well as various laboratory tests thought to necessary, were done. While family study revealed(see pedigree) that one of the patient's aunt and her mother had suffered from the illness which seemed similar with the patient's present illness, and two of her siblings were also found to have suffered from the almost identical illness in the past. Examination of urine also revealed excess in amount of porphobilinogen and uroporphyrin in the urine. Authors stressed the importance 1) interdepartmental consultation, and also of 2) the needs of careful review and evaluation of the results of the basic and further laboratory tests for which paychiatrists tend to pay less attention to those cases with neurotic manifestations.

치아종을 동반한 석회화 치성낭의 치험례 : CASE REPORT

이상엽,김대업,이광희 大韓小兒齒科學會 2004 大韓小兒齒科學會誌 Vol.31 No.4

석회화 치성낭은 비교적 드문 낭으로 하나의 독립된 유형의 치성 병소로 인정받고 있지만, 조직학적 소견이 다양하고 분류체계도 학자들마다 다르다. 석회화 치성낭의 이장상피는 중층편평상피로 되어 있으며, 상피층 내에 특징 세포인 유령세포가 출현한다. 유령세포들은 인접한 결합조직에 치성조직을 유도할 수 있는 능력을 가지고 있어 법랑모세포종, 법랑모세포 치아종, 법랑모세포 섬유치아종, 치아종 등의 치성종양이 합병되어 발생하기도 한다. 외과적 제거 후 재발율은 적지만 치성종양이 병발될 경우가 있기 때문에 반드시 조직병리학적 검사를 수행하여야 한다. 7세 남아가 상악 좌측 중절치의 미맹출을 주소로 원광대학교 치과병원 소아치과에 내원하였다. 방사선 사진에서 맹출되지 않은 상악 좌측 중절치 및 측절치 치관 상방에 방사선 불투과성 물질이 보였다. 초기 임상적 방사선학적 검사 결과 치아종으로 진단하였으며, 외과적 적출 및 생검을 시행하였다. 적출물은 불규칙적인 석회화 물질로 구성된 복잡 치아종 양상을 보였으며 상피조직으로 싸여 있었다. 조직병리학적 검사 결과, 이장상피에서 유령세포의 군집이 관찰되었고, 석회화 조직은 법랑질, 상아질 형태의 조식들이 혼합된 양상을 보여, 복잡 치아종을 동반한 석회화 치성낭으로 진단하였다. 본 증례에서와 같이 매복치 상방의 치아종 양상의 병소가 관찰 되었을 때 석회화 치성낭의 가능성을 염두에 두어야 할 필요가 있다. Calcifying odontogenic cyst(COC) is a rare developmental odontogenic cyst, which shows diverse classification and terminology. Cystic epithelial lining of COC is composed of basal cell layer of columnar cells and overlying layer of stellate reticulum. In the epithelium, ghost cells that might induce adjacent mesenchymal tissue to develop dental organ are shown characteristically. In spite of low rate of recurrence, we have to get a histopathological examination so that odontogenic lesions may recur without fully curettage of lining epithelium. 7-year-old male child came pediatric dentistry in wonkwang university dental hospital in order to check the delayed eruption of left maxillary central incisor. Radiographic examination revealed a well-defined radiopaque mass, overlapping impacted left central and lateral incisor crown. Enucleated mass was tooth-like features and also had epithelium lining. Results of histopathologic procedure, we saw the lots of ghost cell and proliferating hard dental tissues. Also we saw the cystic epithelium cells. It revealed diagnosis of the COC associated complex odontoma. For this reason one should consider of COC when patients present odontoma-like lesion with impacted tooth.
