Drowning is the second most common cause of accidental death of children in Korea. But the study of near-drowning is very rare in Korea. The purpose of our study is to determine the factors that may influence survival on the basis of submersion time, consciousness state upon admission to hospital, the kinds of water, laboratory findings and neurological outcomes. The survey was performed by a retrospective cohort study on 28 near-drowning victims of less than 15 years of age who were admitted to the emergency room in the Chosun University Hospital between May 1988 & May 1997. The results were as follows :1)Sex distribution was 22 males and 6 females. 2) Submersion time was <5 minutes in 9 cases, 5-9 minutes in 6 cases, 10-14 minutes in 5cases, 15-19 minutes in 3 cases, ≥20 minutes in 5cases. 3) Comatose patients upon arrival were 6/7 cases in the death group(86%) and 2/21 cases in the improved group(10%). They had unfavorable outcomes(P<0.05). 4) The first PH value was mean 7.02±0.12 in the death group and mean 7.31±0.13 in the improved group. There was a statistically significant difference between the death and the improved group(P<0.05) 5) The patients who gad increased blood glucose concentration were all 7 cases in the death group and 12/22 cases in the improved group(54%). The mean blood glucose concentration was mean 424.7235.6㎎/㎗ in the death group and mean 140.182.7㎎/㎗ in the improved group. There was a statistically significant difference between the death and the improved group(P<0.05). 6) The patients who had pulmonary edema upon arrival were all 7 cases in the death group and 1/21 cases in the improved group(46%). They had unfavorable outcomes(P<0.05). 7) The patients who had been submerged more than 15 minutes were all 7 cases in the death group and 6/21 cases in the improved group(5%). They had unfavorable outcomes(P<0.05). We conclude that pediatric victims of near-drowning can be assigned to high or low likelihoods of unfavorable our outcomes with the use of five variables ; comatose mentation upon arrival decreased initial blood pH, increased initial blood glucose concentration, pulmonary edema, and maximum submersion time estimated longer than fiften minutes. This prediction rule may be useful if it can be validated in another cohort.

특수콘크리트를 이용한 가로 경관시설물 개발에 관한 기초연구

박봉우,한갑수 강원대학교 석재복합신소재제품연구센터 1997 석재연 논문집 Vol.2 No.-

본 연구는 특수 콘크리트를 사용하여 가로경관 시설물 관련 제품을 생산하기 위한 기초 자료를 얻을 목적으로 수행하였다. 조사는 기존의 도시 가로를 구시가지, 신시가지, 문화거리로 구분하여 가로 경관 시설물을 현황을 조사하였다. 장소에 따른 가로 경관 시설물을 종류는 크게 다르지 않았으며, 시설물의 소재(사용재료)는 철제품이 주종을 이루고 있었다. 또 이들 가로 경관 시설물은 도로에 관련된 정보 전달을 위한 기능성에 치중하고 있고, 경관 기여도는 낮은 것으로 평가되었다. 이렇게 조사된 결과를 토대로 하여 경관 기여도를 높일 수 있는 수목용 플랜터(planter for trees and shrub)와 자연성의 도입을 유도할 수 있는 생태블럭(eco-block)의 모형을 제시하였다. This study is conducted to collect basic data for special concrete material to be applied for making street furniture and related products. For this purpose, this study first classified existing city streets into old town area, newly developed area and cultural street, then surveyed the number and the kind of street furniture located in them. In result, the survey showed that the street furniture was not different among the streets in terms of kind, and steel including nonferrous metal was used as the main material for it, and the contribution to the landscape was limitied. Based upon the results, we suggest the pilot models of a planter for trees and shrubs which can make a greater contribution to the surrounding landscape, and of an eco-block to give naturalness to the urban settings.

노안가입도에 따른 다초점렌즈 착용선호도 연구

박수봉 김천대학교 2003 김천대학교 논문집 Vol.24 No.-

Fifteen subjects were fitted with progressive additional lens and they were divided into 3 groups. The first group had never worn add for reading before and their adds ranged between +1.00 - +1.50D. The second group made up of wearers who had been wearing a standard from of bifocal before switching to progressive additional lens and their adds fell in the +1.75 to +2.00D range. The third group comprised subjects who had been wearing a standard form of bifocal before choosing the progressive lens and their adds utilized a +2.25 to +2.50D. After wearing identical near power in blended bifocal, 13 subjects preferred to wear the progressive additional lenses. The second experiment subjects were 20 people and had never worn pro- gressive lens before. The first group whose add ranged between +1.00 and +1.50D. 4 of 6 had never worn adds for reading before. Eight subjects com- prised a group whose add powers fell in the +1.75 to +2.00D range. Only one of these had not worn some addition for near before. The final 6 required adds of +2.25 and +2.50 and had been wearing a near point addition for some time. Some tried the blended lenses first and then the progressive lenses while some wore the progressive lenses before the blended. 15 chose the progres- sive additions, with two selecting blended lenses and 3 returning to a stan- dard form. The experiment reveals that given any opportunity to compare the optical aspects of both blended bifocals and progressive addition lenses, the over-whelming propotion of subjects selected a progressive addition lens. A blended bifocal, despite the fact that it also caters to cosmetic favor through its invisibility is not an actual substitute for or replacement of a progressive addition lens insofar as apparent optical features and patient comfort and preference is concerned.

金捧秀,朴涌基,康秉秀 대한본초학회 2001 大韓本草學會誌 Vol.16 No.1

Rubi Fructus is a well known remedy for female infertility, especially due to lack of kidney-yang or shenyangxu(???). An attempt was made to evaluate the influences of Rubi Fructus (mature Rubus crataegifolius BUNGE, mature Rubus coreanus MIQ and immature Rubus coreanum MIQ) on the morphological changes of the ovary. The experiment was performed to investigate the effects of the seeds of mature Rubus cratagifolius BUNGE (W1), the seeds of mature Rubus coreanus MIQ (W2) and the seeds of immature Rubus coreanus MIQ (W3) on the formation of follicles in rat ovary. The results are as follows: 1. Results using three herbs of mature seed of Rubus cratagifolius BUNGE (W1), mature seed of Rubus coreanus MIQ (W2)and immature seed of Rubus coreanus MIQ (W3) clearly showed the stimulating effects on the increasing number of follicles in rat ovary. Of them, W1 increased the follicle formation by 171% compared to normal control after 4 days of treatment. In cases of W2 and W3, the formed numbers of the follicle were increased to 228% and 285%, respectively. On the other hand, the follicle formations of W1, W2, and W3 were most effective, showing 208, 258 and 266%, respectively, after 8 days of treatment. These results showed that effect of immature Rubus coreanus MIQ was similar to that of the mature Rubus coreanus MIQ without any differences. 2. The size of the follicle stimulated by W2 was about 1.0 mm, although the size of the normal control was 0.3 mm. However, those of W1 and W2 were about 0.5 mm, indicating that the treatments of the herbal extracts are also effective for the follicle size. Therefore, it was concluded that all these herbs showed the effects on average of follicles in ovary. Especially, mature Rubus coreanus MIQ showed the highest effect among them. 3. Fractions of W1-B, W2-B and W3-B, when each extract were separated by analytical HPLC(high performance liquid chromatography), showed the activities of follicle number and size of follicles in ovary. These results suggest that the effect of Rubi Fructus is related to treatment of female infertility due to ovulation difficuty. Of them, mature Rubus coreanus MIQ is the most potent effector on the ovulation in Rats.

실온에서 알루미늄 산화층(SiO_2)-반도체〔Si(100)_p형〕 소자의 경계면 반응을 Ar^+이온 sputter총을 부착한 AES로 수행했다. SiO_2-Si 경계면은 Si-Si 결합, Si-O 결합의 두 가지 상태를 갖고 있으며, 경계면 넓이는 약 30Å였다. Al-SiO_2-Si 반도체 소자의 경계면 반응은 SiO_2 속의 자유 실리콘이 알루미늄 표면으로 확산되고, 알루미늄과 SiO_2 경계면에 대량의 자유 실리콘이 존재한다. Al-interfacial layer(SiO_2)-semiconductor Si(100)_p-type structures were investigated by the Auger Electron Spectroscopy. The results of depth profiling Ar^+ -ion sputtering are presented for the SiO_2-Si(100)_p-type cell. In the interface, Silicon exists in only two distinct bonding states: Si-Si or Si-O bonding. The exact width of the interface is known as indefinite, but here we estimate it approximately 30Å. The results of depth profiling Ar^+ -ion sputtering are also presented for the Al-SiO_2-Si(100)_p-type cell. Metal(Si) atoms from deposited interfacial oxide layer were observed on the Al surface. The interfacial reaction takes place between Al and the interfacial layer at the room temperature. The diffusion of metal(Si) atoms from the interfacial layer towards the Al surface is suspected to play a role in degradation effect in the MIS solar cells.

박완수,최훈,홍기섭,박봉수,배현덕 충북대학교 컴퓨터 정보통신 연구소 2000 컴퓨터정보통신연구 Vol.8 No.1

적응알고리듬의 VLSI 구현에 있어서 파이프라이닝이나 시스토릭과 같은 구조적 설계기법을 이용하여 알고리듬을 변환하는 것은 효과적이다. 알고리듬 변환은 z-변환 영역에서 연산의 규칙성과 반복성을 찾아 이루어 진다. 본 논문에서는 이차원 필터와 계수갱신 시스템을 시스토릭 구조로 설계하여 LMS의 확장 형태인 TDLMS을 STDLMS로 변환한다. 변화된 STDLMS를 이용 이차원 ALE를 Altera사의 Max-PlusII 상에서 구현하여 시뮬레이션을 통해 성능을 평가한다. 시뮬레이션 결과 salt-pepper 잡음과 가우시안 잡음에 오염된 화상을 ALE가 개선할 수 있음을 보였다. In VLSI realization of adaptive algorithm. it is necessary and efficient that the algorithm is transformed to structural one suitably using architectural design techniques such as pipelining or systolic array. These transform method use regular and recursive of operation of the algorithm on z-transform domain. In this paper, the TDLMS which is a extended version of LMS is transformed to STDLMS which has systolic array architecture in two dimensional filter and coefficients update system. The transformed STDLMS is applied for realization of two dimensional ALE. And the ALE performances are evaluated by Max-PlusII of Altera Co.. The simulation results show that the ALE enhances image data which were corrupted by salt-pepper noise and Gaussian noise.

This study was compared and analyzed the differences in the academic achievement of the students of the Department of Ophthalmic Optics, who were classified according to method of admission selection, origin. ages, participation levels in the events held by the department, and gender, in the first semesters of the years 2002 to 2004. This study was aimed to find out if these factors affected the academic achievement of the students. The standard GPA was set at 4.5 and the students whose records show a grade of F in all subjects, or those who were regarded as not having had the intention to complete the semesters under study were not included among the subjects of the study,According to the method of admission selection. those students who enrolled in the department through college or higher degrees course graduate selection processes had the most superior academic records while those students selected, through a special selection process, from agriculture and fisheries communities showed the worst academic records. According to origin, those students from Gyeongsangnam-do achieved the most superior academic records while those students from hoongcheongbuk-do showed the worst academic records. This, howev-er. excluded those regions from which less than 5% of the students came According to ages, 30-34 year-old students showed the best academic results, and the students under the age of 23 showed the least impres-sive scholastic achievement. According to participation levels in the events held by the department, no significant difference in scholastic achievement was observed. According to gender, the academic records of the female students were superior to those of the male students, but the differences were relatively small.
