박영제,김양배,전방욱,김형섭 江陵大學校東海岸地域硏究所 1993 東海岸硏究 Vol.4 No.1

영동지역에 위치하는 4개 저수지를 대상으로 1991년 9월에 수질조사 및 식물성 플랑크톤 분포에 의한 오수생물학적 수질평가 연구를 시도하였다. 수질평가를 위하여 수온, 수소이온농도, 총질소, 총인, 엽록소 a, 및 식물성 플랑크톤의 현존량을 조사하였다. 동정된 식물성 플랑크톤은 총 58종류로 남조류 10종, 황색편모조 1종, 와편모조 2종, 갈색편모조 1종 및 녹조류 37종류였다. 식물성 플랑크톤의 우점종은 저수지별로 달랐으며, 죽헌저수지는 Microsystis aeruginosa, 북동저수지는 Peridinium cunningtonii var. contactum, 달방댐은 Staurastrum simonyi var. simonyi, 초당저수지는 Chlamydomonas umbonata로 밝혀졌다. 수질 및 식물성 플랑크톤의 분포유형을 기준으로 호수 수질을 생물학적으로 판정할 때 죽헌, 북동 및 초당저수지는 β-중부수성 호수로 달방댐은 빈부수성 호수로 판정되었다. The survey of water quality and saprobiotic phytoplankton distribution was carried out in 4 reservoirs in eastern area of Kangwon Province at September 1991. Temperature, pH, total-N, total-P, chl.a, and standing crop of phytoplankton were measured for water quality examination. Total numbers of phytoplankton identified were 58 spp, consisted of 10 spp Cyanophyta, 1 spp Chrysophyta, 2 spp Dinophyta, 1 spp Crytophyta, and 37 spp Chlorophyta. The dominant species of phytoplankton in each reservoir was different as follows: Microsystis aeruginosa in Jukhean, Peridinium cunningtonii var. contactum in Bukdong, Staurastrum simonyi var. simonyi in Dalbang, and Chlamydomonas umbonata in Chodang. Estimated from the data of water quality and phytoplankton distribution, the reservoirs of Jukheon, Bukdong and Chodang were β-mesosaprobic whereas Dalbang was oligosaprobic.

서울 북촌의 공간구조 분석을 위한 방법론 연구 : 가로형태의 도시맥락적 분석을 중심으로 focused on urban contextual analysis of street network

김영욱,신행우 대한건축학회 2004 대한건축학회논문집 Vol.20 No.9

This paper investigates the morphology of the urban grid focused on spatial syntax of configuration. Bukchon is used as a Unique case study since it draws a great concern m studying its spatial and housing morphology because of well preserved traditional street network and housings despite its location in the center of Seoul 'Space syntax' is applied to analyze syntactic properties of spatial configuration quantitatively Axial maps are used to examine the morphology of Bukchon m two ways, both in its urban context and the area independently, since the two different approaches in studying morphology allows us in depth understanding The findings show that the 'intelligibility' of street network of Bukchon is relatively low m the urban context as well as m the area itself, thus the area is lack of 'legibility' m Lynch's tenn The order of 'integration' m the global and local context does not coincide, the former is in the order of Yulgok-Ro, Samchungdong-Gil and Bukchon-Gil and the latter is in Gahoidong-Gil and Geodong-Gil The majority of traditional housing is located in 35 Samchungdong area where globally segregated but locally integrated area, however intelligibility of the area is relatively high Which may help to acquire sense of community Whereas relatively few traditional housings are remained in 11, 15, 33 and 35 GahOldong area which is globally more integrated and close to the most integrated street, Gahoidong-Gil, however this area is at least 1 depth away from the most integrated street, thus it appears to have less development pressure and resulted m more traditional housing This research suggests quantitative characteristics of spatial layout of Bukchon and, at the same time, possibility of applying space syntax method in morphology studies

합병증이 동반된 Meckel씨 게실 2례 보고

정병욱,박동일,이준희,서정욱,원유홍,김웅,신현종,권영무 동국대학교 경주대학 1996 東國論集 Vol.15 No.-

합병증이 동반된 Meckel씨 게실을 가진 환자의 치료에 대한 필요성은 과정이 문제이다. 하지만 우연히 만나는 게실의 처치는 논란 중이다. 부수적인 게실 절제술(incidental diverticulectomy)의 제안자는 증상이 있는 게실의 외과적 처치는 중요한 이환 및 사망률은 지적한다. 이를 반대하는 사람들은 전 생애를 통해 합병증의 위험성이 낮게 나타나므로 필요가 없다고한다. 게실의 예방적 제거는 개복술시 우연히 발견 될 때 시행한다. 이는 남아있는 게실이 나중에 합병증을 일으키는 것보다 술후 합병증의 위험성이 매우 적음을 알 수 있다. 저자들은 합병증이 동반된 Meckel씨 게실 2예를 경험하였기에 문헌 고찰과 더불어 보고하는 바이다. The necessity for therapy with complicated Meckel's diverticular is a matter of course.However, management of the incidentally encountered diverticulum is controversial. Proponents of incidental diverticulectomy point to the significant morbidity and mortality rates of surgical treatment of symptomatic divenicular. Other authors base their opposition to incidental diveniculectomy on the low risk of complications developing during lifetime. Prophyillctic removal of the diveniculum is indicated when it is found incidentally at laparotomy, because there are few postoperative complications and the risk exists that the remaining diverticulum may be the cause of later complication. The 2 cases of complicated Meckel's diverticulum are reported with a brief review of literature.

김영하,전방욱,박광하,이성원 강릉대학교동해안지역연구소 1994 東海岸硏究 Vol.5 No.1

강릉남대천의 BOD를 1990년 4월부터 1993년 12월까지 모니터하였다. 강릉수력발전소의 발전수 방류 결과, 방수구와 홍제보의 BOD는 증가하는 경향을 보였으나, 하구의 BOD는 감소하는 경향을 나타내었다. 회귀분석에의하면 방수구와 홍제보의 매월 BOD 증가율은 공히 0.031mg/l이었으며, 하구에서의 매월 BOD 감소율은 0.071mg/l였다. The BODs of Namdaecheon Stream, Kangnung were monitored from April, 1990 to December, 1993. BODs at water outlet and Hongjebo were gradually increased, while BOD at estuary was decreased due to water discharged from Kangnung hydropower plant. The increasing rates in BOD at water outlet and Hongjebo were both 0.031mg/l month and the decreasing rate at esturary was 0.071mg/l month by linear regression analysis.

김영기,차태준,변주현,고광욱,이용환 大韓産業醫學會 2000 대한직업환경의학회지 Vol.12 No.1

목적 : 산업장 근무 근로자들에 있어서 소음 노출이 혈압과 심박동수에 미치는 영향을 조사하고자 하였다. 방법 : 부산시 소재 한 주물공장 근무 근로자로서 소음 작업장에 근무하는 102명에 대하여 1998년 3-6월, 1999년 3-6월에 걸쳐 안정시 혈압과 청력손실정도, 일반적 특성이 조사되었다. 소음노출 정도는 noise dosimeter를 사용하여 오전 8시-오후 4시까지 8시간동안 측정하여 평가하였고, 활동 중 혈압과 심박동수는 ambulatory blood pressure로 오전 8 시-오후 10시까지 30분 단위로 측정하였다. 결과 : 연령과 흡연, 신체비만지수의 영향을 고려하였을 때 저연령층에서 85dBA이상의 고소음에 노출된 군에서 소음과 수축기 혈압간에는 유의한 양의 상관관계가 있었으나, 이완기 혈압과 심박등수에서는 유의한 결과를 얻지 못하였다. 연령의 구분없이 상관관계를 구하였을 때에는 수축기 혈압에서만 소음수준과 유의한 상관성이 있었다. 오전 8시-오후 10시까지 측정한 활동 중 혈압과 심박동수의 일일 변화는 40세미만의 저연령층에서는 심박동수에서만 근무후의 오후시간부터 감소하는 양상이 있었고 수축기 혈압과 이완기 혈압에서는 뚜렷한 변화를 발견할 수 없었다. 40세이상군에서는 수축기혈압과 이완기 혈압, 심박동수 모두 근무 중에는 비교적 높은 값을 유지하다가 오후부터는 감소하는 추세를 보이고 있었다. 각 연령군별 소음노출수준에 따른 활동 중 혈압과 심박동수의 비교에서는 40세미만의 연령층에서만 85dBA이상의 고소음군에서 심박동수가 유의하게 더 높은 결과를 얻었다. 결론 : 저연령층인 40세피만에서 85dBA이상의 고소음에 지속적으로 노출될 경우 수축기 혈압이 증가되어 있을 수 있음을 확인하였다. Objectives : This study was carriel out to evaluate the effects of Industrial noise on blood pressure and heart rate. Methods Resting blood pressure, hearing loss, and general characteristics of the 102 subjects who were engaged In a factory in Pusan were measured from March to June for two years, in 1998 and 1999. With noise dosimeter, noise exposure level was measured from 8 A.M. to 4 P.M. Ambulatory blood pressure and heart rate were also measured every 30 minutes from 8 A. M. to 10 p. M. Results : Controlling for age, smoking, and Quetelet's index, in subjects of under 40 years old exposed to higher than 85dBA, noise exposure and systolic blood pressure had astatistically significant correlation, and the same result was obtained in all subjects. The daily variability of ambulatory blood pressure and heart rate were observed in older than 40 years old group, but only heal·t rate in under 40 years old. Conclusions : The blood pressure and heart 1·ate would be elevated when the workers exposed to noise. And in under 40 years old, the systolic blood pressure was elevated to the workers exposed to higher than 85dBA.

Pusan has experienced some different paths of urbanization and industrialization compared to other cities, and has faced the problem of over-saturation in environmental capacity. Pusan needs to find out sustainable development strategies based on Agenda 21 by UNCED in 1992 to secure urban renewal. Therefore, Pusan's sustainable development strategies focus on the 1)research on environmental capacity and reasonable population accommodation 2)supply of basic environmental facilities for the human settlement 3)protection and efficient management of environmental pollution 4)saving and control of energy and other resources 5)independent and stable execution of plan based on biological relation 6)harmony between nature and urban spatial organization. In addition, these policies can be suggested along with the conclusions; First, establishment of green plan-middle and long term environmental goals included in the urban planning to reduce environmental deterioration and pollution. Second, computation of sustainability index-the index is necessary to sustainable urban development, which is related with green GNP of the national level. Third, capacity estimation of nature and social environment-estimation of environmental capacity to the civilized area is required become an ecopolis, and is required to focus on the western area of Pusan which has high degree of potentiality.

압연용 ROLL의 열처리를 위한 ROLL내의 열전단 해석

金煜中,尹英煥 國立 昌原大學校 産業技術硏究所 1987 産技硏論文集 Vol.1 No.-

In order to provide the technical guidance for heat treatment process of a back-up roll which is a rolling part of a press for hot iron, unsteady solutions of temperature distributions, in which thermodynamic properties of specific heat, Cp and thermal conductivity, K are a function of temperature, are solved by finite-difference numerical method. First, unsteady solutions to heat conduction equation with the known surface temperature in a infinite solid bar are investigated to obtain proper thermodynamic properties and the surface heating rate of the roll. These solutions are also compared with the calculated and experimental data reported by kobe iron company. Second, the unsteady 2-dimensional solutions with radiative and convective boundary conditions in a real roll with irregular shapes are obtained, where the numerical method of the Implicit-Alterating-Direction is used. From these calculation, the following results are obtained. 1) The heating area near the surface of the roll, which is a important place for the heat treatment, does not much depend on variation of thermodynamic properties of the roll. 2) A high or low limitation of the surface heating rate is considered. 3) The thermal radiation analysis with the weighted sum of gray gases model is effective to predict the gas temperature in the furnace. 4) The even insulations on both side of a real roll are required to obtain a uniform heating temperature contour near the surface.

As interests on illumination recently arise all over the world in the point of urban environmental view, people widely use illumination for urban environment as environmental art and making economical profits. In domestic, illumination widely takes part in improving the quality of night urban environment and attracting tourists. However, not like above intentions, since urban plan does not include urban illumination plan as a part and promotes it separately, we had to take the burden of economical loss and environmental quality deterioration. Consequently, this study analyzes space syntax and space using pattern objectively, and applied the Space Syntax Theory, which is used worldly for checking problems in planning, designing of existing cities, and buildings, in order to study the relationship with space characteristic factor and special factors in illumination plan, and then design illumination intensity estimation model through space syntax characteristic factors. Based on above results, this study suggests the methodology of illumination intensity plan using Space Syntax Theory for changes in space syntax or illumination plan for new cities in the future.

프로그램 재해석에 따른 공간구조의 분석 : 렘 쿨하스의 뉴욕 프라다 매장을 중심으로 Focused on New York PRADA designed by Rem Koolhaas

A Program always has been the element of architecture, which has advented since 18C. And it has been changed simultaneously with the alteration of architecture. In modern architecture, the functionalism handles with a program as rational and functional side of architecture. When a social change progresses and gets complex, a program of architecture also gets complex. A new interpretation about program appeared in response to the functionalism, in which the form and the configuration of a building was decided with its use. One building denoted singular program, but now it includes diverse programs. The program itself shows not only with the function of a building but also with social sense. As a result, the form and the configuration of a space is closely related to a program. This paper considers alterations of program accompanied by social changes and finds out the relationship between new programs and space configurations. And also, we are trying to use space syntax which is a quantitative method to analyze physical space configurations. New York PRADA, designed by Rem Koolhaas, coexists with two programs such as commerce and culture, and shows the relationship between a contemporary society and a new program. Searching for the relationship of space configuration and program, we find out the alteration of space configuration in the contemporary society. In the future, this could develop a comparative study of space configuration in modernism buildings which are used with the same purpose. Also space analysis based on the scientific theory will be a foundation in understanding various complex spaces.
