Pressure sore is an area of ischemic tissue loss resulting from prolonged or often repeated pressure, usually over a bony prominence of body. Recently, the prevalence of pressure sore is major clinical problem, due to the increased number of patients with spinal cord injuries or longterm comatous patient after traffic, industrial accidents. The surgical principles in the treatment of pressure sores are total excision of the ulcer, scartissue, bursae, complete removal of all infected bone with recontouring of bony prominences to alleviate discrete pressure points and resurfacing and padding of the defects with healthy and well vascularized tissues. The sacral sore is the most common site for the development of pressure sore in Korea. We had experienced 14 cases who had received surgical treatments for sacral sores with transverse lumbosacral back flap. We obtained the following conclusions. Advantages 1)It is quick and easy procedure 2)The flap elevation itself is relatively bloodless 3)The donor defect is in a non-weight-bearing area 4)Muscle is not sacrified(possibly of importance in the ambulatory patient) 5)Surgical options are preserved in cases of recurrence(the flap itself may be reelevated and inset in some cases of recurrence) Disadvantages 1)It is lacking the bulky padding afforded by alternative musculocutaneous flaps 2)The vascularity of the flap tip is empirically less dependable than that of a musculocutaneous flap 3)The donor defect is large, cannot usually be closed primarily, and may prove of cosmetic concern

Fracture of frontal bone is infrequent, but may have serious complications because of their proximity to the brain, eyes and noses. Fractures of the frontal area range from 5% to 15% of all facial bone fracture and include supraorbital rim and frontal sinus. As frontal bone fractures most frequently occur in the multiply injured patient, a thorough clinical and radiological examination of the patient is required before diagnosis and treatment plans are established. Sometimes coorperative treatment with other department is requried. It is specially considered that incision for access to frontal region and surgical methods for open reduction, cranialization, cannulization, sinus obliteration. After surgical or conservative treatment, it may have complication. Complication of frontal bone injury vary in severity and may occur at several years after the incidents. The major types of complications are those that occur directly at the time of injury, infection and chronic problems. This is clinical study on 31 patients with frontal bone fracture, at department of oral and maxillofacial surgery in dental hospital of Wonkwang university during past ten years. The results were as follows : 1. The sex ratio of all patients is 29 (94%) male to 2 (6%) female, the average age is 33 and the prominent groups are 2nd, 3rd decade age. 2. The causative factors are mostly traffic accident 22 cases (70%) and fall dawn, industrial accidents, so on. 3. The 17 cases has shown alert mental status, but neurologic problems is in 14 (45%) cases in initial accessment. 4. Associated facial bone fractures are prominent in the maxilla (42%) and panfacial fracture (39%). 5. Involved general problems are in department of neurologic surgery problems (65%), orthopaedic problems (23%) and ophthalmologic problems (19%) in order. 6. Open reduction has done in 15 cases and 16 cases with conservative management. 7. Postoperative complications are chronic headache (42%), esthetic problems (39%) and ophthalmologic problems (35%)in order.

This study suggests an improvement of building height regulation in urban area with a historic landmark, by an adoption of the observer-oriented building height regulation. A rigid-angle height regulation system that is current secures no pertinent perspective around the historic landmarks. Through a case study of 'Dong-dae Mun' with height calculations and 3D visual simulations, the observer-oriented building height regulation is proven to make more available space with less obstacles in the perspectives around historic landmark.

이상용,이창근,이건모 한국전과정평가학회 2001 한국전과정평가학회지 Vol.3 No.1

철판가공 공정군에서 범용성이 높은 용접공정, 절단공정 및 프레스공정 등의 철판가공 공정에 대한 전과정평가를 수행하였다. 각 대상 공정군별 국내 공정가동량이 가장 큰 4개 업체 선정하여 전과정 목록 데이터베이스를 구축하였다. 용접공정의 세부 용접공정에는 gas metal arc welding(GMAW), flux cored arc welding(FCAW), submerged arc welding(SAW) 및 spot welding 등에 대한 전과정목록 데이터베이스가 구축되었다. 절단공정에는 플라즈마 절단 및 산소-아세틸렌 절단, 프레스에서 3500 가압력 톤 수 프레스의 전과정목록 데이터베이스가 구축되었다. 추가적으로 절단 및 프레스 공정에서는 데이타베이스의 활용도를 높이기 위해 각 기능단위별 투입물에 대한 상관관계를 토대로 환경부하계산식을 작성하였다. 전과정평가 수행결과 용접공정군의 경우 각 용접기법과 용접 모재의 종류별로 영향 범주에 따라 환경영향이 차이가 있었지만 모든 용접공정에서 무생물 자원고갈 범주가 50% 이상으로 전체 환경영향에 가장 기여도가 큰 것으로 나타났다. 절단공정군의 경우에는 공통적으로 생태독성 범주가 전체 환경영향에 55%이상으로 가장 기여도가 큰 것으로 나났다. 프레스공정은 무생물자원고갈 범주가 전체 환경영향에 80%이상으로 가장 기여도가 큰 것으로 나타났다. Environmental performance of teel sheet processing processes was investigated by implementing a Life Cycle Assessment(LCA). The inventory analysis was performed with data obtained from four major companies Cycle Assessment(LCA). The inventory analysis was performed with data obtained form four major companies within the country. The selected processes were welding, cutting and pressing process. In welding process, there were gas metal arc welding(GMAW), flux cored arc welding(FCAW), submerged arc welding(SAW) and spot welding. In cutting process, there were oxygen-acetylene cutting and oxygen-plasma cutting. In pressing process, there was 3500 ton press. Especially for cutting and pressing process, we made some equations with regard to each input such as electric power and mineral oil to activate the utilization of the life cycle inventory database. As for welding process, environmental impacts vary according to the kind of parents metal. However, the most significant impact was the abiotic resource depletion. In the case of cutting and pressing process, eco-toxicity and abiotic resource depletion were identified as the most contributing impact respectively.

The motive of this study stemmed from two recent events : (1) The first event was to create merchant banks(merchant banking corporations)system out of all non-main stream banking operations, consolidating existing merchant banks and all investment & finance corporations during the period of 1970 throughout 1996. (2) During the same period it has been found that there has been and unprecedented insolvency experience for the merchant banking industry. Therefore this paper consists of five chapters, including this chapter of 1) the motive and scope of the study, 2) an analysis of current status of the merchant banking industry, 3) issues on present credit screening by the merchant banking industry, 4) a suggestion for Korean merchant banks on firms' credit screening by a variety of evaluation techniques found in literature, 5) conclusion and further studies.

오덕근,윤상현,김정민,김상용,김정회 한국미생물생명공학회 ( 구 한국산업미생물학회 ) 1996 한국미생물·생명공학회지 Vol.24 No.4

Candida parapsilosis ATCC 22019 돌연변이주를 사용하여 xylitol 생산에 영향을 주는 배지성분의 최적화를 수행하였다. Xylose 50 g/l 배지에서 여러 가지 질소원이 xylitol 생산에 미치는 영향을 살펴본 결과 xylitol 생산에는 무기질소원으로는 (NH_4)_2SO_4가 좋았으며 유기질소원으로는 yeast extract가 가장 좋았다. 무기염으로 KH_2PO_4 ad MgSO_4·7H_2O를 선정하여 최적화를 수행하였고 그 결과 최적배지로 xylose of 50 g/l, yeast extract of 5 g/l, (NH_4)_2SO_4 of 5 g/l, KH_2PO_4 of 5 g/l, MgSO_4·7H_2O of 0.2 g/l로 결정하였다. 최적배지를 사용하여 발효조에서 64시간 배양하였을 때 xylose는 모두 소모되었으며 최종 균체농도와 xylitol 생산량은 각각 7.6 g/l와 37 g/l을 얻었다. 이때, xylose로 부터 xylitol의 전환수율 74%이었고, xylitol의 생산성은 0.58 g/l-hr이었다. 최적배지에서 총 첨가된 xylose에 대한 xylitol의 생산수율 80.7%에 해당되었고 xylitol의 생산성은 0.94g/l-hr에 해당되었다. Medium optimization for xylitol production from xylose by Candida parapsilosis ATCC 22019 mutant was performed. Effect of various nitrogen sources on xylitol production was investigatied. Of inorganic nitrogenous compounds, ammonium sulfate was effective for xylitol production and yeast extract was the most suitable orangic nitrogen nutrient for enhancement of xylitol production. Effect of inorganic salts such as KH_2PO_4 ad MgSO_4·7H_2O on xylitol production was also studied. Optimal medium was selected as xylose of 50 g/l, yeast extract of 5 g/l, (NH_4)_2SO_4 of 5 g/l, KH_2PO_4 of 5 g/l, MgSO_4·7H_2O of 0.2 g/l. In a fermentor by using the optimal medium, a final xylitol concentration of 37 g/l could be obtained from 50 g/l of xylose with a xylitol yield of 74% and a xylitol productivity of 0.58 g/l-hr. At 300 g/l xylose, fermentation was also carried out and then a final xylitol concentration of 242 g/l was obtained at 272 hours. It was corresponding to xylitol yield of 80.7% and xylitol productivity of 0.58 g/l-hr.
