Recent experimental studies and clinical cases have suggested that grafting tissue from the adrenal medulla into the brain may alleviate the symptoms of Parkinson's disease. Autologous adrenal medullary grafts into the striatum was performed stereotactically in two patients with Parkinson's disease. Both patients were bedridden preoperatively, but 4 months after the surgery both became ambulatory and one was even capable of returning to his job. Even though the number of cases was small⑵ and the follow-up period was short, this study shows that adrenal medullary transplantation into the striatum may have some beneficial effects in patient with Parkinson's disease. Further experimental and clinical trials are necessary to see whether this procedure will be a recommendable surgical treatment for patients suffering from Parkinson's disease.

朴然欽,金連相,南成祐 成均館大學校 科學技術硏究所 1989 論文集 Vol.40 No.1

Electrically conducting PVDF/PAN/poly(pyrrole) composite r s have teen prepared by polymerizing pyrrole vapor in PVDF/PAN composite films impregnated with ferric chloride as an oxidant. As polymerization of pyrrole proceeds, poly(pyrrole) has been observed as uniform continuous phase in PVDF/PAN composites. The electrical conductivities of composite films reach in the range of 10^-3∼10^-2S/cm and the stability of conductivity to the ambient air exposure is excellent. The formation of poll (pyrrole) in PVDF/PAN composites has induced increasing disorder in host composite matrix and increased the tensile elongation.

박흠기,김경덕,이상민 강릉대학교동해안지역연구소 1999 東海岸硏究 Vol.10 No.2

전복의 영양소 요구에 관한 연구 결과들을 검색하면서 실험 배합사료를 기존의 수입 배합사료와 비교하기 위하여 실험 배합사료 2종, 수입사료 2종 및 천연먹이(미역)를 선정하여 평균체중 2.6g 전후의 참전복 (1년생)을 구입하여 각 사료마다 3반복으로 15주간 사육 실험하였다. 생존율은 모든 실험구에서 95% 이상으로 양호하였으며, 실험구간에 유의한 차이는 없었다 (P>0.05). 최종 평균체중은 미역 공급구가 가장 낮아 실험 배합사료 및 상품사료보다 유의하게 낮았으며(P<0.05), 실험 배합사료와 상품사료 공급구간에는 차이가 없었다 (P>0.05). 가식부 중량 및 패각성장의 변화도 이와 유사한 경향을 보였다. 실험종료시 전복 가식부의 수분함량은 실험구간에 유의적인 차이는 없었다. (P>0.05) 가식부 단백질 함량은 두 실험 배합사료 공급구가 상품사료보다 유의하게 높았다. (p<0.05). 실험 배합사료 및 상품사료 공급구의 지질 함량은 미역 공급구가 가장 낮은 값을 보였고 (P<0.05), 실험 배합사료 공급구의 지질 함량은 상품사료보다 높은 값을 보였다.(P<0.05). 실험 배합사료구의 성장 효과가 수입 상품 배합사료와 차이가 없는 것으로 나타나 이 배합사료 조성비는 상품 사료의 배합비로 사용이 가능 할 것으로 기대된다. A feeding experiment was conducted to evaluate experimental and commercial diets for growing abalone(Haliotis discus hannai). Three replicate groups of the abalone average weighing 2.6 g were fed two experimental formulated diets containing 33.5% protein and two commercial diets containing 34.2-36.5% protein for 15 weeks. Experimental formulated diets with 20% fish meal and 20-23% soybean meal as protein sources were included. In addition, these experimental and commercial diets were compared with natural food (Undaria). No significant (P>0.05) differences were found among abalone fed the experimental and commercial diets in survival rate, final average weight, shell length and body weight/shell length ratio. Weight and shell growth of abalone fed the natural food (Undaria) were significantly lower than those of abalone fed the experimental and/or commercial formulated diets (P<0.05). These data indicate that experimental formulation used in this study could be used as a practical diet and dietary value of Undaria is lower than formulated diets.

박연흠,원성연 成均館大學校 科學技術硏究所 1990 論文集 Vol.41 No.2

The tensile properties of poly(ethylene terephthalate) filament yarn have been investigated by varying the drawing temperature under the constant draw ratio of 3.0. The breaking strength and elongation increases with the drawing temperature upto 85℃, but above 85℃ they decrease with the drawing temperature. The yield stress and yield strain have also shown the similar trends. The density increases with the drawing temperature upto 85℃, but above 85℃ the density of 1.38g/㎤ has been maintained. Thus it is suggested that the optimum drawing temperature of poly(ethylene terephthalate) filament yarn is around 85℃ under the draw ratio of 3.0.

박연흠,박학수,남성우,안동문 成均館大學校 科學技術硏究所 1992 論文集 Vol.42 No.2

Electrically conducting nylon 6/polypyrrole composite films and fabrics have been prepared by polymerizing pyrrole vapor in nylon 6 matrix containing cupric chloride as an oxidizing agent. After polymerization of pyrrole for 30 min, the conductivities of composites reach as high as 10^-3∼10^-2 S/cm depending on the content of oxidizing agent. The stability of conductivity to ambient air exposure is excellent ; there occurs little change in conductivity on exposing the composites to ambient air for one month. The nylon 6 composite fabrics containing 14∼25 wt.% of polypyrrole show an excellent antistatic properties.

박상흠,양승하,강상균 순천향대학교 1994 논문집 Vol.17 No.2

Study to carcinoembryonic antigen(CEA) in various cancers had been progressed actively. CEA was inadequate in specific diagnostic value but useful in detection of metastasis, recurrence, and prognosis of cancer. Study to expression of CEA used immunoperoxidase stain in tissue of TCC was infrequent. Therefore, to understand positive rate of CEA in TCC of urinary bladder, the author performed immunoenzyme histologic reaction by Abidin-Biotin-Complex method using anti-human CEA rabbit serum and analuzed their histologic reaction. Results are following as 1. Positive reaction of CEA in TCC was 36(45%) among 80 cases. 2. In papillry form of TCC,positive reaction of CEA was 8 cases(44%) in grade I, 21(55%) among 38 cases in grade II, and 5(36%) among 14 cases in grade III, respectively. 3. In flat form of TCC,CEA showed positive reaction in 2 (20%) among 10 cases. 4. Noninvasive form of TCC showed CEA Positive reaction in 23(44%) among 52 cases, invasive form to submucosa 9(45%) among 20 cases, and invasive form to muscle 4(50%) among 8 cases, respectively. The above results showed high positive rate of CEA in well differentiated carcinoma, and the more deeper invasive form the more high positive rate of CEA in the transitional cell carcinoma of urinary bladder.

Polystyrene/Cd arachidate 혼합 LB막의 제조와 구조적 성질

박연흠,남성우,박성윤 成均館大學校 科學技術硏究所 1992 論文集 Vol.43 No.2

The spreading behavior of mixed monolayer of polystyrene with arachidic acid at the air-water interface was studied by measuring the surface pressure(π)-surface area per molecule(A) isotherms. Since polystyrene has no hydrophilic group, the π -A isotherms appear to support that polystyrene exists in a dense spherical form at the air-water interface. The observed transfer ratio and wettability indicated that the mixed LB films have been deposited in Y-type. Through the X-ray diffraction measurements, the structure of polystyrene/Cd arachidate mixed LB films has been confirmed as well-ordered structure.

Background : It is one of the important daily activities for Korean students to use the Internet, and most of them go to FC bang. However, students uncontrolled Internet use causes compulsive Internet use, so called the Internet addiction. So we investigated the relationship between students internet use pattern and their Internet addiction. And also examined how internet addiction causes VDT syndrome. Method: We conducted survey with self-registered questionnaires for 1 months, from January to February 2000. On the questionnaire, we asked Internet use pattern to students in suburban area. To test the Internet addiction, this research adopted Dr. Young s Internet addiction self test, and also major 8 symptoms of VDT syndrome were tested. Results : There was not much difference in computer using time between at home and at PC bang, and among student s grade. We found 30.1% of the objects addicted to the internet, however, there was no relationship between Internet addiction and student s grade. We found statistically significant relationship between Internet addiction and VDT syndrome (p<O.o5) except ocular symptoms and dry mouth. Conclusion : As a result, we found that Internet adhction is related with the spending time on computer use, although there is no relationship between Internet addiction and student s grade. There are significant correlations between internet addiction and VDT syndrome. So internet addiction is not only social and psychiatric problem but a physiologic dsorder whch affect student s health.

인도의 토지개혁과 농민운동

박종수,백좌흠,장상환 서울대학교 국제지역원 1995 국제지역연구 Vol.4 No.4

이 연구는 독립 후 인도 토지개혁의 전개와 이에 따른 농민운동을 중심으로 한 사회 경제적 구조변화를 밝혀내는 것을 주요한 목적으로 한다. 독립 후 인도 정부가 시시했던 농업 계획과 시책은 크게 다음의 세 가지 범주로 분류할 수 있다. 즉 ① 토지개혁, 농업협동조합의 확충, 유통기구의 개선, 제도 금융의 증강 및 이자 규제 등의 제도 개혁 ② 비료, 개량종가 공급 및 관개, 개간 사업 실시를 통한 효율적 재배방법의 보급 및 개량 농법의 도입 ③ 농산물 지지가격, 작물보험, 수입제한, 보조금 지급 등 경제적 인센티브 제공이 그것이다. 토지개혁은 독립전에 이미 국민회의당(National Congress Party)의 기정 방침이었기 때문에 독립 직후부터 '토지를 경작자에게'(Land to Tillers) 제도의 폐지, 소작제도의 개혁, 토지보유의 제한과 초과토지의 재분배를 내용으로 하고 있다. 이중 자민다리제도의 폐지와 소작제도의 개혁은 1950년대 말가지 시행되었고 토지보유의 제한과 초과 보유지 재분배조치는 50년대 말까지 입버을 완료하고 60년대 초 이후 시행되었다. 그러나 실제 각주의 토지개혁법에서 폐지되었던 것은 지주제가 아니고 바로 자미다리제도 및 라이야트와리(Ryotwari)제도 였으며, 따라서 새롭게 창설되었던 제도도 '본질적 의미'의 자작농제도(自作農制度)가 아닌 '광의의 경작개념'에 기초한 자작농제라고 할 수 있다. 그 결과 지주제도의 폐지는 실패했으며 자민다리 지주의 대규모 '자경지'(自耕地)소유가 인정되었다. 자경 용도의 소작지 취득이 합법화되었으며 결국 토지보유의 최고 한도가 높은 수준으로 설정되었던 것이다. 이렇게 토지개혁에 의해서 창출되었던 자경 농업은 협의 의 자작농 즉, 농민적 토지소유에 기초한 소농경영뿐만 아니라 주로 농업노동자를 고용하고 소유토지를 임대하는 부농경영(富農經營)도 포함했던 것이다. 결국 독립직후 시작된 인도의 토지개혁은 당초 계획과는 달리 기생적인 자민다리 지주층이나 농촌 고리대업자의 경영지주화 혹은 부농경영으로의 전화를 촉진한 반면 영세 소작농이나 농업노동자는 더욱 몰락하게 되었다. 본 연구는 모두 5개의 장으로 이루어 진다. 머리말에 이어 2장에서는 토지개혁의 주요한 촉발요인으로 작용한 인도 농민운동의 전개과정을 요약하고 이에 따른 사회경제적 구조변화를 밝힌다. 3장에서는 구체적인 토지개혁의 내용과 수행과정을 밝히고 4장에서는 토지개혁의 불철저와 녹색혁명으로 인한 분배적 불평등요인 등에 의해 야기된 1950년대 이후의 농민운동을 개관해 보고 마지막으로 5장에서 전체의 내용을 요약한 후 마무리하기로 한다. Changes in agrarian structure can occur in either of the two ways; (1) as a result of the spontaneous operation of socio-economic processes, and (2) as a result of direct intervention are characterised as land reforms. The need for direct intervention in the form of land reforms emanated in India from the exploitative nature of the land tenure system prevailing during the pre - independence period. It was basically to stop the exploitation of the actual tillers of the soil and pass on the ownership of land to them that land reforms were introduced in the post-independence period in India. Measures contemplated to achieve the objectives were abolition of intermediaries, tenancy reforms, reorganization of agriculture. Here, tenancy reforms included following set of measures: regulation of rent, security of tenure, ownership right for tenants. And the reorganization of agriculture included the following policies: redistribution of land, consolidation of holdings, cooperative farming. But land reforms in India have trailed miserably because of snags in legislation, lack of political will, and apathy of the bureaucracy, and so on. Narrowly defined, the Green Revolution is the rapid growth in the Third World grain output associated with the introduction of a new package of tropical agricultural inputs. The package consists essentially of a combination of improved grain varieties, mainly rice and wheat, heavy fertilizer usage and carefully controlled irrigation the new varieties usually yield no more and sometimes less than traditional strains. As a result, disparities between rich farmers and poor farmers grew as only the farmer were capable of adopting it. The most important effects of the Green Revolution on political tensions might be grouped into four categories: intensified regional conflict, changes in the form of rural class struggle, the growth of an urban lumpen, and the speedup of changes. In these context, this paper highlights the agrarian reforms and socio-economic changes of India after Independence.

박흠기,김동주,이상민 강릉대학교 동해안지역연구소 1999 東海岸硏究 Vol.10 No.2

A 20-week growth trial was conducted to investigate the utilization of brewer's yeast as an additive in formulated diets on growth and body composition of juvenile abalone (Haliotis discus hannai). Four replicate groups of the abalone averaging 63 mg were fed the formulated diets containing 0% and 3% brewer's yeast. In addition, these formulated diets were compared with natural food (dried Laminaria). Survival rate, growth performance and proximate analysis of abalone fed the diet containing brewer's yeast were not significantly different to control diet (P>0.05). These values of abalone fed the formulated diets were higher than those of abalone fed the dried Laminaria (P<0.05). These data indicate that supplemental brewer's yeast is not needed in this formulation and dried Laminaria is not adequate diet for juvenile abalone.
