강신몽,이원태,이한영,서중석,최영식,권일훈,정낙은 大韓法醫學會 2000 대한법의학회지 Vol.24 No.2

The authors analysed 53 cases of sudden cardiac death(SCD) without prominent structural abnormalies of heart out of witnessed 300 cases. Thirty four cases were associated with sleep and 19 with activity or rest. Twenty one cases were classified as having normal hearts, and the rest as structurally mild abnormal ones. Male was predominant, and almost of the victims were suffered in their twenties or thirties. All cases collapsed instantaneously or in very short time with various and not specific terminal symptoms. Inducing or trigger factors are not clarified in almost of the cases. Mechanisms or causes of death could not be defined clearly. We concluded that careful heart examination with detailed clinical history under the appropriate postmortem investigation system is only effective approach for the true mechanism and cause of death.

강석중,정우건 國立統營水産專門大學 附設 水産科學硏究所 1994 수산과학연구소보고 Vol.5 No.-

새로운 양식 대상종으로 메기의 생산량 증가를 위하여 사료 중 최적 단백질 함량을 설정 하고자 실험한 결과는 다음과 같다. 평균 체중 약 7g되는 메기 치어의 체중은 사료중 단백질 함량 25%~55% 사이에서 단백질 함량이 높은 사료를 공급할수록 증가하였으나,근육 단백질의 증가는 45% 부근에서 최고치에 달하였으며,그 이상으로 사료 단백질 함량을 증가시켜도 변화가 없었다. 단백질 효율 및 정미 단백 이용율은 25% 부근에서 최고치에 달했지만 45% 부근에서 일시적으로 증가하여 단백질 함량 45% 실험구가 가장 양호한 것으로 나타났다. 따라서 멸치분을 단백질 원으로 하였을 때 메기 치어 사료의 최적 단백질 함량은 45%로 사료된다. Feeding trials were conducted for a test of the optimum dietary protein levels for the fingerling Korean catfish, Parasilurus asotus. The growth response was examined in terms of weight gain, feed coefficient, protein efficiency ratio and net protein utilization for 8 weeks at 23~27℃. Within a range of 25 to 55% crude protein levels in the diet, the body weight increased while the dietary protein level increased. Accumulation of protein in the body reached the maximum when the crude protein level in the diet was at 45%. These results indicate that the optimum dietary protein level of fingerling Korean catfish was about 45% when anchovy meal was used as the protein source.

강석중,최병대,정우건 國立統營水産專門大學 附設 水産科學硏究所 1994 수산과학연구소보고 Vol.5 No.-

양어 사료에 피드오일을 첨가하면 사료 효율이 향상된다. 나일틸라피아가 요구하는 필수 지방산의 종류를 알아보기 위하여 대두유 및 옥수수유 등의 식물유 및 오징어 간유, 어유를 사료에 첨가하고 사육하여 다음과 같은 결과를 얻었다. n-6 계열이 풍부한 식물유를 투여한 실험구가 n-3 계열의 어유를 투여한 실험구 보다 성장이 좋았으며 그 중에서도 대두유 첨가구가 가장 양호하였다. 총 지질중의 20:3n-9의 수준은 유지의 종류에 따라 현저한 차이는 없었으나 극성 지질중의 20:3n-9의 수준은 어유 및 오징어 간유 보다는 식물유구에서 낮게 나타났다. 틸라피아 사료에 첨가하는 지질로서는 n-6계열을 많이 포함하는 것이 적당할 것으로 나타났다. Experiments were conducted to find out suitable dietary lipids in the practical feed for Nile tilapia, Oreochromis niloticus. Soybean oil, corn oil, fish oil or cuttlefish liver oil was mixed in the diet and tested. The best weight gain and feed efficiency were obtained from the fish fed soybean oil or corn oil, both rich in 18:2n-6. But the growth rate of fish fed diet with fish oil or cuttlefish liver oil were inferior. The levels of 20:3n-9 in the total lipid were not different in all tested lipids, but that in the polar lipid of the fish oil or cuttlefish liver oil were lower than that in the soybean oil or corn oil. Thus, vegetable oil such as soybean oil or corn oil, rich in 18:2n-6, were suitable as dietary lipid for Nile tilapia. Unlike other fish species, fish oil or cuttlefish liver oil showed no essential dietary value for this species.

강석중 漢城大學校 1985 論文集 Vol.9 No.1

A country's trade control system is formulated under the background of it's historical, social, economical and cultural ones as well as for the direction of prosperious futures. The systematic control system is being improved based on the current situation. We can find a good illustration in E.C. that each country of the member has it's own system eventhough it consists of on economical bloc Suggestions for a better import controls in Korea are ; a) Make every endeavors to make the country's trade balance even or reduce it's trade deficit. b) Adjust/control the demand of imports for reducing external debt. c) Increase export and the ratio of trade added value. In a word, we have to take the direction of contraling import under the conception of saving foreign currency payment through reducing unnecessary imports.

강석중,최병대,정우건 國立統營水産專門大學 附設 水産科學硏究所 1994 수산과학연구소보고 Vol.5 No.-

보통잉어와 이스라엘잉어를 같은 조건에서 사육하였을 때 두 품종 간의 체성분 변화를 조사하기 위하여 식물성 플랑크톤이 많은 동일한 조건에서 사육한 보통잉어와 이스라엘잉어의 아미노산 및 지방산 조성을 분석하였다. 근육과 내장의 일반 성분을 분석한 결과 근육 중 조지방의 함량은 보통 잉어가 높았고, 회분은 이스라엘잉어가 높았으며 내장 중의 조지방의 함량은 이스라엘 잉어가 휠씬 높았으나, 회분의 함량은 비슷하여 지방의 함량에서 차이가 있었다. 구성 아미노산의 함량 및 패턴은 비슷하였고 주된 아미노산은 aspartic acid, glutamic acid, leucine 및 Iysine이었으며 전체 함량의 약 42%를 차지하였다. 또한 필수 아미노산이 차지하는 비율은 38~43%으로 높았다. 유리 아미노산 중 주된 성분은 taurine과 histidine이었으며 이들이 맛에 영향을 줄 수 있으나 두 품종 간에는 이들 함량이 비슷하였기 때문에 맛에는 차이가 없을 것으로 사료된다. 지방산 조성은 극성 지질 중 eicosapentaenoic acid(20:5n-3) 및 docosahexaenoic acid(22:6n-3)의 함량이 높아 건강 식품으로서의 가치가 있는 것으로 나타났다. The differences of nutritive components in muscle and viscera of local and Israeli strains of common carp were examined. The crude lipid content in muscle was higher in the local carp than in the Israeli carp, but that in viscera was lower in the local carp than in the Israeli carp. There was no appreciable differences of crude protein and ash in viscera between local and Israeli carp. The distribution patterns of the total amino acid profiles for both local and Israeli carp were very similar. The principal amino acids were aspartic acid, glutamic acid, leucine and Iysine. They were 42 percent of total amino acids. Taurine and histidine were important part of free amino acids. Eicosapentaenoic acid and docosahexaenoic acid content in the polar lipids were high in both strains.

강진성,권건영,송중원,오석희,한기환 大韓成形外科學會 1989 Archives of Plastic Surgery Vol.16 No.5

Many orientals have a more prominent malar eminence and mandibular angle than westerners so their faces often look rough and unattracive. In recent years more people want to have a more attractive and beautiful face due to economic prosperity and westernization. Therefore people receiving bone shavings or osteotomies for cosmetic purposes are increasing. The effects of the periosteum on lay bone grafts were investigated but the effect of the periosteum after bone shaving or osteotomy is little known. The authors investigated the effect of the periosteum on the regeneration of bone in membranous and endochondral bone of rabbits. Bony defects each measuring about 5.0×5.0×1.5mm were made on the left and right sides of the parietal bones of 15 rabbits and femurs of 15 other rabbits respectively. The periosteum was preserved on the left and removed on the right. The following results were obtained: 1) The average thickness of the regenerated bones in groups 2 δ4 were thinner than those in groups 1 δ 3 at 4, 8 and 12 weeks postoperatively but the differences of thickness were statistically significant at onl 4weeks postoperatively(P<0.05). 2) The histological findings in groups 2 δ 4 showed lesser regeneration of the shaved bone than those in groups 1 δ 3 at 4, 8 and 12weeks postoperatively. 3) There was no significant increase in the thickness of the regenerated bone after 8 weeks postoperatively in all groups. 4) At 12 weeks postoperatively, the thickness of the regenerated bone in all groups was over 70% of the thickness of the resected bone. In summary, the authors found that it is important to perform overcorrection and resect the periosteum simultaneously in bone shaving to prevent the unwanted regeneration.

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.

우리나라 貿易關聯法令의 時代的 變遷에 관한 硏究 : 立法背景과 主要內容을 中心으로 With emphasis on the background of legistration and the main contents

姜錫中 건국대학교 1988 論文集 Vol.26 No.1

At this manuscript, studying the background of legistration and the main contents of trade laws /regulations since the independent of Korea(1945), the writer classified the period into five items from the period of military administration to the present of foreign trade law in the process of the periodic change of the trade laws/regulations in Korea. The writer could find that the common which showed in the process of phase of law indicated that a restriction and a control was more relaxed. And the writer could find that there are still a lot of restrictive structure of laws/regulations. They are as follows ; - Trade license and registration system of trading company - Listed foreign trade items - The permission system of primate transaction - Foreign currency payment controls - Various restrictions of foreign trades - Export driving system Thus this kind of restricted system should be liberlized step by step to simplify the process of Import-Export and to adapt widly the principle of liberalization of trade. In the process of the application of the present law, there are themes for promoting the efficiency. First, to cope with the strength of private econmic. Second, to meet the change of internatinal trade situation. Third, to harmonize between the restriction of government and the freedom of enterprises. We may need to study in the near future to how it compare with the law system and to how it internationalize the direction between America, Japan, which they are advanced country, and Taiwan which is competing with Korea.

유중선,김석범,강복수 大韓産業醫學會 1996 대한직업환경의학회지 Vol.8 No.2

산업장 근로자들의 건강과 관련된 변수 및 행태를 조사하고, 그들이 원하는 건강증진 내용을 각 근로자의 특성별로 조사하여 비용-효과적인 근로자 건강 증진 프로그램을 개발하기 위해 1995년 12월부터 1996년 1월 사이에 실시된 40개의 근로자 일반 건강검진 및 특수검진 사업장에 근무하는 근로자 500명을 무작위로 추출하여 검진 실시와 병행하여 이 연구를 위해 개발된 설문지를 이용하여 자기기입식 방법에 의해 자료를 수집하였다. 현재 직장에서 실시하고 있는 건강증진 활동으로는 야외운동이 14.8%로 가장 많았으며, 정기적 건강검진, 실내운동 및 맨손체조 순이었다. 남자에서는 야외운동이 가장 많이 수행하는 건강증진 활동이었으며, 여자에서는 정기적 건강검진이 가장 많았다. 전체적으로 여자에 비해 남자의 건강증진 활동률이 더 높았다. 앞으로 현재근무하는 직장에서 실시되기를 희망하는 건강증진 활동은 정기적 건강검진이 26.2%로 가장 많았으며, 건강상담, 실내운동 및 야외운동 순이었다. 남자에서는 정기적 건강검진이 33.7%로 가장 많았으며, 그 외에도 건강상담, 실내운동, 야외운동 순으로 희망하였다. 여자에서는 체중관리 프로그램이 21.4%로 가장 많았고, 정기적 건강검진, 건강상담 등의 순이었다. 근무부서별 희망 건강증진 활동은 생산직의 경우 남녀근로자 모두 정기적 건강검진을 가장 선호하였고, 사무직의 경우 남자는 정기적 건강검진을, 여자는 체중관리 프로그램을 가장 많이 희망하였다. BMI 지수별 희망 건강증진 활동은 저체중 근로자 중 남자는 영양교육을, 여자는 체중관리 프로그램을 가장 선호하였다. 정상체중에 속하는 여자 근로자들도 체중관리 프로그램을 가장 선호하였다. 규칙적인 운동 및 식사를 하는 근로자는 남녀 모두 정기적 건강검진을 가장 선호하였으며, 규칙적인 운동 및 식사를 하지 않는 근로자 중 여자는 체중관리 프로그램을 가장 선호하였다. 남자 근로자는 음주 및 흡연 여부에 관계없이 정기적 건강검진, 건강상담 및 실내운동 순으로 선호하였다. 이상의 결과로 앞으로 가장 우선적으로 실시해야 할 건강증진프로그램은 정기적 건강검진이며 현대 실시중인 근로자 정기신체검사에 대한 만족도가 낮아 검진의 내용과 방법에 대한 개선이 요구되며 여성근로자들에 대한 체중 및 영양에 대한 올바른 지식 및 태도를 갖도록 하는 교육프로그램과 흡연근로자들을 대상으로 하는 금연프로그램의 필요성을 고취시켜야 하겠다. This study was conducted to identify the demand of work-site health promotion program of employees. A self-administered questionnaire method was used to collect data from 492 employees from 40 work-sites in Taegu City and Kyungpook Provincial area. The work-site health screening programs conducted for several years were placed low value by employees. The out-door exercise was the most popular health promotion activity implemented at work-site as a whole. The employees expressed that periodic health check-up, the health counseling, indoor exercise would be implemented as a health promotion program in the future. The male employees regarded that the periodic health check-up program should be established preferentially at work-site. However, the female employees gave priority to fitness program. The health related behavioral patterns slightly influenced the preference of health promotion program. The health screening program for employees should be improved and the health education of nutrition and diet for female employees should be implemented.
