최영규,구본기 한국기술교육대학교 2002 論文集 Vol.9 No.1

In the past decade, significant effort has been made toward increasing the accuracy and robustness in the three-dimensional scanning methods. In this paper, we introduce a novel laser-stripe 3D scanning system which was developed to digitize a whole human body. Our scanning system, 3D Model Studio, was developed to capture a whole human body and to create 3D digital model in a few minutes. We describe the way our system automates the realistic 3D model generation, followed by some experimental results to show its capability.

The Asan Bay area Korea is situated in an unbalance or water supply and demand relating to the Ansung, Sapkyo, Dangjin and Youmwha rivers and their estuary reservoirs. The multi-reservoir operation was studied by the Hierarchical Operation Model for Multi-reservoir System(HOMMS) assuming that these four estuary reservoirs were linked to each other in order. The result of this study shows that storage capacity deficiency in 2011 was estimated as 8 MCM in the Sapkyo and 31 MCMin Dae Ho estuary reservoir, respectively. In case of linking four reservoirs, the water deficiency will not occurs in all the reservoirs even if additional agricultural water of 78 MCM/yr was supplied. Total additional water demand for agricultural, municipal and industrial uses was estimated as 321.9 MCM /yr while additional supply by linking the reservoirs was estimated as 160.4 MCM/yr, 50% of additional demand. The remaining 161.5 MCM/yr would be supplied transferring other watershed.

To flood forecastion, until now, Storage function method, Streamflow Synthesis and Reservoir Regulation, and HEC-1 model have been analysed generally in various definite simulation. Generally, Streamflow Synthesis and Reservoir Regulastion and HEC-1 model are more delicacy and more excellent model than Storage function method in physically.But the resource huge for test of moels. On the contrary, Storage function method has not only a few model various and data for decisionbut also has poor theory background in model excessively simpled water circulation asbout a basin. In this reason, this study is purpose to develop a statistical flood forecasting model that can forecast with accuracy variety of water height to Nak-Dong river vibration spots in flood with accumulated water resource.

연구목적: 반복적인 스트레스에 노출된 실험동물에서 opioid성 신경전달의 변화양상을 검색하고 내인성 opioid peptide의 변화양상을 알아보기 위하여 본 연구를 시행하였다. 방 법: 본 연구에서는 웅성 흰쥐에게 하루 2시간, 2주간의 반복적인 부동화 스트레스를 가한 후 뇌의 각 부위에서 opioid 수용체의 mu-, delta- 및 kappa- 아형의 최대결합력 및 친화력의 변화 양상을 관찰하였다. 결 과: 반복적 부동화 스트레스 노출군에서는 대조군에 비하여 delta-아형 수용체의 수가 시상하부(hypo-thalamus) 및 선조체(striatum)에서 증가하였다. 본 연구결과 관찰된 선조체에서의 delta-아형 수용체의 상향조절과 관련지어 delta-아형 수용체의 내인성 효현제인 enkephalin의 뇌조직 내에서의 활성도를 검색하였을 때, 반복적 스트레스 노출군에서는 대조군에 비하여 그 함량이 감소하였다. 이러한 뇌조직내 enkephalin 활성도 감소 현상은 수용체 변화와 상응하게 시상하부 및 선조체에서 관찰되었으며, 이러한 수용체의 조절 현상은 내인성 수용체 효현제인 enkephalin의 활성도의 감소에 따른 생체의 적응 현상으로 해석되었다. 결 론: 이상의 결과로부터 반복적인 스트레스는 opioid 수용체 delta-아형을 상향조절하였으며, opioid 수용체 delta-아형의 내인성 효현제의 활성도를 감소시킴을 관찰하였다. Objectives : Research into emotional or behavioral stress typically focuses upon the hypothalamic-pituitary-adrenal axis. It is well established that the hypothalamic-pituitary-adrenocortical axis is subject to inhibitory control by opioids in a variety of animal species including pigs. Exposure to acute stress induces the upregulation of opioid receptors and the release of endogenous peptides which mediate the stress-induced analgesia. There is some literature substantiating that repeated stress can lead to changes in opioidergic neurotransmission. However, the changes are highly variable. This study was designed to observe the modulatory effect of repeated immobilization stress on opioidergic neurotransmission. Methods : Male Sprague-Dawley rats weighing 150-200g were forced to suffer immobilization stress for 2 hours on each of 14 successive days. Then we examined the maximum binding capacity and affinity of each opioid subtypes(mu, delta, kappa). Results : Repeated immobilization stress increased the binding of [³H]DPDPE on the delta-subtype opioid receptor in the striatum and hypothalamus. Saturation experiments followed by scatchard analyses of the results showed an increase in the density of delta-subtype opioid receptors, but the affinity of the delta-subtype opioid receptor remained unchanged. Repeated immobilization stress reduced enkephalin activity of striatum and hypothalamus. Conclusions : From these results, it could be concluded that repeated immobilization stress up-regulated the delta-subtype opioid receptors and reduced the activity of enkephalin, an endogenous ligand for the delta-subtype opioid receptor.

Various forms of disinfection or sterilization used in the early must have been empirical, based on experience, tradition and after superstition, and they must have been developed in entire ignorance of the theories of sterilization. Although several thousands of years later our approachh to sterilization or disinfection is much more rational, our knowledge of the fundamental theories and processes remain far from complete. It is still true to say that we understand only a very small part of the activities of bacteria. The purpose of the present study was to investigate the effect of thermoradiation on Pseudomonas aeruginosa ATCC 10145, Staphylococcus aureus 29, Escherichia coli 0111, Bacillus subtilis ATCC 6633, Salmonella typhimurium, using electronic range (RE-515-W 0. 53 cu. ft. ) The rate of inactivation of these culture was exponential and in direct proportion to temperature. Significant synergism between heat and irradiation was noted 70℃ above. The combined effect of heat and high frequency wave was more destructive to bacteria than heat alone 70℃ above.

The algae content in the Nackdong river water, which is used as source of water works in Daegu city and carries a pollution load of domestic and industrial wastewater, rises in the warm season to such a level that calls for a improvement process for water treatment. A pilot plant study on the efficiency of the removal of algae by dissolved air flotation was conducted and the results are summarized as follows: 1. Algae concentration in the raw water is the highests in April, May and September below 25 NTU of raw water turbidity. In these dry months, the production of treated water decreases by the conventional water treatment process. 2. The average efficienct of algae removal could be achieved at 96% using coagulants, such as alum or PAC at dissolved air flotation. In the conventional sedimentation process, algae can be removed by only 88% and produces chlorinated organic compounds after breakpoint chlorinatioin. 3. It is required that the ideal flotation area is 7,106㎡ and the detention time is 20 min for treated water of 250,000㎡ /day.

Epidemiological studies were done on the 162 hypertensive cerebrovascular accid-ents cases admitted in the affiliated Oriental Medicine School Hospital Kyung Hee University in 1983 and the following results were obtained. 1. The male to female ratio of the patients was 1. 3 : 1 and the age distribution frequency was as follows; fifties, forties, seventies and thirties(Table 2). 2. In the C.T.A., there were 119 cases of cerebral thrombosis(73.5%) and 45 cases of intracerebral hemorrhage (26.5%). The ratio was 2.8 : 1. In the former the male to female ratio was 1.3 : 1, in the latter it was 1.2 : 1(Table 3). 3. There were considerable numbers of recurrent cases as shown in Table 4. The first attack was noted in 125 cases(77.2%), the 2nd attack 30 cases(18.5%), the 3rd attack 6 cases(3.1%), 4th attack 1 case(0.6%). The male to female ratio was as follows. In the first attack it was 1. 3 : 1, in the 2nd attack 1.1 : 1, the 3rd attack 5.0: 1, the 4th attack was noted only in one male case. 4. The occupational frequency order was as follows(Table 5). Unemployed initi-ated with 45 cases(27.8%), home care 21 cases, Unspecified 19 cases, office worker, business men, farmers and public official etc. 5. The regional distribution was as follows(Table 6). Seoul city led with 102 cases (63. 0%) then it was followed by Kyung-Gi, Chung-Cheong, Kyung-Sang, Kang-Won and Jon-Ra province. 6. The systolic pressures at admission were disclosed as follows(Table 7). There were 42 cases(male 20 cases-12.3%, female 22 cases-13.6%) of systolic hypertens-ive over the WHO standard of 160mmHg, the mean value of systolic pressure was 145mmHg. The diastolic pressures at admission were shown as follows(Table 8). There were 92 cases(56.8 %) (male 48 cases-29.6%' female 44 cases-27.2%) of diastolic hypertension over the WHO standard of 95mmHg, the mean value of diastolic pressure was 98mmHg. 7. The patient's favors to salty food, animal fatty food, cigarettes and alcoholic beverage were examined (Table 9). Salty' foods were favored by 78 cases(48.2%), animal fatty foods by 78 cases(48.2%), cigarettes by 64 cases(39.5%) and alcohol imbibers were noted in 77 cases(47.5%) as shown in table 9. 8. The family history of C. V.A and hypertension was studied (Table 10). In C. V.A there were 28 cases (17.3%) with parental history, 12 cases (7.4%) with siblings history and 7 cases (4.3%) with other relatives, and in hypertension there appeared 14 cases(8.6%) with parental history, 9 cases(5.6%) with sibling history and 6 cases(3.7%) with other relatives. 9. In the past history, hypertension led with 124 case s(76.5°%), then C.V.A 37 cases(22.9%) and diabetes mellitus 33 cases(20.4%)(Table 11). 10) In treatment the frequently used herbal recipes were Gamichungshimtang(), BoSimgunbitang( ), Kyuntongdudamtang( ) in 15% of the cerebral hemorrhage cases, respectively; Camichungshimtang( ) in 20% Yangkyeuksan(), Chowishungchumtang(), Yukmichihwangt-ang() in 6%, respectively, in cerebral thrombosis. The most frequently used acupuncture points in C. V. A were shown in Table 12. Taechung(), Habgok ( ), Joksamri(), Oekwan(), Chungjue( ), Jokimueb.(), Kokji(), Taebak() were frequency order used in C.V.A of both cerebral thrombosis and hemorrhage. 11. In admitted C.V.A patient care, it was stressed that the Oriental Medical Hospital plays important roles and, accordingly, the propriety of East-West medical cooperation was addressed. 12. Through classified disease distribution of admitted patients in the Oriental Medicine Hospital the epidemiological epitome of cerebrovascular accidents and other diseases was presented. * East-West medicine denotes a methodology of approaching a creative medicine through cooperation between East-West medicines.
