We introduced mechanical stimuli and micro patterned substrate with micro fibers to investigate the effects of those on neurite outgrowth along with nerve growth factor (NGF) in vitro. Micro fiber substrates were fabricated using an electros pinning process. And PC-12 cells cultured on substrates were simulated with newer growth factor and laminar flow shear stress in a fluid flow system. The results suggest that micro fiber substrates and fluid-induced shear stress are promising for simulating neuronal regeneration in a desired direction.

As medical technology progresses rapidly, there is a rise in the average age along with the Korean dietary lifestyle becoming more westernized, which leads to an increase in the number of vascular disease patients in Korea. Thus, we need to manage the medical information of a disease systematically in order to diagnose and treat constructively. However, since there has been no standardized method of man agement to date, a great deal of information could not be properly utilized nor studied. Therefore, the departments of Cardiology, Radiology and Neurology of Samsung Seoul Hospital recently got together to develop an information management system called the Vascular Data System. This program was developed to be run on win98 O/S, upper Pentium Ⅲ, and upper 128 MB Memory, and its source code is Dephi 4.0. It was configured for the user to set the configurations as well as do a variety of search and analysis. If this program were to be updated continuously, it may be used extensively as well as in various parts of clinical research activities.

본 연구에서는 생물학적 인 제거공정의 혐기-호기-무산소 조건을 단일 반응조내에서 발생토록 고안하여 인제거 실험을 수행하였으며, 고안된 반응기내에서의 인 제거기전을 규명하고 제거효율을 평가하였으며 또한 내부반송율과 SRT 변화에 따른 유기물과 인제거 효율을 평가하였다. 고안된 공정의 종합적 인제거효율 평가를 통해 최적 운전조건을 평가·분석하였다. 실험 결과 유기물 제거율은 Aerobic recycle rate 100%, 200%에서 TOC 95% 이상, BOD와 COD 90% 이상으로 우수하였으며, 인은 Aerobic recycle rate 100%에서 폐수유입 지점 0.2일 때가 최적조건으로 분석·평가되었다. SRT 변화와 T-P, PO₄-P 제거율과의 관계는 SRT 10일에서 94%, 92% 이상으로 높은 제거효율을 나타내었다. In this investigation, phosphorus removal experiment was conducted in a single reactor combining anaerobic-aerobic-anoxic zone. Attempts have been made to delineate phosphorus removal mechanisms and to evaluate the removal efficiency. Also performed in this experiment are the removal characteristics of organic and phosphorus with different internal recycle ratios and varying SRT conditions. In addition, this study evaluates the best operation conditions in terms of phosphorus removal efficiency. The removal efficiencies of TOC, BOD and COD were observed to be higher than 95%, 90% and 90%, respectively with aerobic recycle ratios of 100% and 200%. If is further estimated that the optimal operational conditions for phosphorus removal are observed when the aerobic internal recycle rate is 100% with the wastewater inlet point being 0.2 from the bottom. The percent removal efficiencies are 92% for T-P and 90% for PO₄-P. In case of SRT, higher removal efficiencies are observed with the solid retention time of 10 days than with SRT's of 5 and 20 days. The removal rates observed are 94% for T-P and 92% for PO₄-P with the solid retention time of 10 days.

유산균 투여가 건강한 성인의 분변미생물 및 부패산물 생성에 미치는 영향

신명수,김용재,배형석,백영진 한국미생물생명공학회 ( 구 한국산업미생물학회 ) 1996 한국미생물·생명공학회지 Vol.24 No.2

유산균의 장내균총과 부패산물 생성에 미치는 영향을 알아보기 위하여, 건강한 성인 남녀 6명의 지원자에게 Lactobacillus acidophilus 와Bifidobacterium longum으로 제조한 유산균분말(각각 1.5×10 exp (9) cells)을 하루에 2회씩 2주동안 섭취하도록 하였다. 그리고 지원자 분변으로부터 균총수 변화와 부패산물인 암모니아, indole, skatole, p-cresole량을 측정하였다. 유산균의 투여 기간중에 분변내 bifidobacteria의 수가 8.78±0.39(log cfu/g feces±S.D)에서 9.27±0.29로 증가하였고(p<0.05) 투여 중지후에는 약간 감소하였으며, lactobacilli의 수는 6.15±0.80에서 6.76±0.48로 증가하였다(p<0.05). Enterococcus 균수는 투여 기간중에 6.66±0.80에서 7.72±0.40으로 증가하였다가 투여 중지후에는 감소하는 경향을 보였다. 그리고 혐기성균인 Bacteroides는 투여중에 8.45±0.34에서 9.15±0.21으로 증가하였으나(p<0.01), 유해균주로 알려진 Closridium(lecithinase negative)과 Staphylococcus 균수는 현저히 감소하였다. 그러나, 유산균 투여 실험기간인 6주 동안 분변내 암모니아, indole, skatole, p-cresole의 유의적인 농도변화는 없었다. To investigate the effects of lactic acid bacteria administration on fecal microflora and putrefactive metabolites in human being, Lactobacillus acidophilus and Bifidobacterium longum powder (1.5×10 exp (9) cells, respectively) was administrated to six healthy volunteers (average 28 years old) twice a day for 2 weeks. During the administration of lactic acid bacteria, the numbers of bifidobacteria, lactobacilli, and enterococci in feces were increased significantly, whereas those of Staphylococcus and lecithinase-negative Clostridium were decreased considerably. In addition, a number of anaerobic Bacteroides were increased. However, the contents of fecal ammonia and putrefactive metabolites (indole, skatole, p-cresole) were not changed during the administration.

Background: High risks of fire alway exist for buildings in urban areas, especially those in downtown. Crowds, as well as more complex and larger structures, may cause more victims in the event of fire; therefore, emergency medical service plans must be established for such disastrous events. Methods: On the evening of October 30,1999, a fire broke out in downtown, Dong-Incheon Live-Hof restaurant; 56 people were killed and 76 were injured. Most of them were teenagers. We retrospectively reviewed the medical records of the victims, Results: 1) Among the 56 dead, 54 died from smoke inhalation, one from extensive burns, and one from sepsis during treatment. 2) Among the 76 injured, 70 patients suffered from smoke inhalation, 53 from burns, and 9 from several types of trauma (sprains, contusions, lacerations, abrasions, fractures, etc.). 3) Later complications were laryngeal edema, pulmonary edema, scar contracture, and hypoxic brain damage, and so forth. 4) Post traumatic stress syndrome was unexpectedly more prevalent in mildly to moderately injured survivors and witnesses than in seriously injured survivors. Conclusion: Many complications exist after a fire. Some may be resolved in time, but others may result in permanent sequelae. Early rescue, early triage, and early management during transport by emergency medical service (EMS) personnel can result in fewer complications and a lower mortality rate. Therefore, we propose the establishment of plans to be followed during various major disasters.

The purpose of this study were (1) to segment the men in twenties and thirties according to apparel shoppong orientation and (2) to create a profile for each group with regard to importance of store attributes, self-image and demographic variables. The questionnaire was administered to men in twenties and thirties living in Seoul and data were analyzed by frequency, percentage, factor analysis, cluster analysis, χ²-test, and one-way ANOVA. The results were as follows: 1) By cluster analysis of apparel shopping orientation factors, three groups were identified: (1) ostentatious shopper(44.5%), (2) practical shopper(21.8%), and (3) individuality-pursuit shopper(33.7%). 2) Three groups were compared on store attributes and self-image. Significant differences were found among the three groups on two variables. Ostentatious shoppers pursued the masculine and sophisticated image and tended to prefer the store image and reputation, convenient transportation and parking place, and variety of products. Practical shoppers pursued the self-image which reflected the conservative and not-noticeable image and considered the moderate price of the products most importantly. Finally, individuality-pursuit shoppers preferred the sexy and noticeable image and considered the display and accommodation of the trendy products. 3) In terms of the demographic variables the significant differences were found on education, occupation, monthly income, and marital status. In general ostentstious shoppers tended to earn higher monthly income than those of the two groups. Practical shoppers tended to be well-educated and individuality-pursuit shoppers tended not to be married.

This study was conducted to investigate wintering ecology and habitat using pattern of cranes for sound protection and management of the birds and their habitat near the Demilitarized Zone(DMZ) of Cheolwon, South Korea. Distribution of cranes seemed to be affected by road construction and human activity. Dried rice paddy was mainly habitat type of cranes in Cheolwon area. Gleaning was dominant behavior during day time. Ratio of alert was increased in afternoon. There was difference in time budget of behavior between red-crowned and white-naped cranes. For the stable wintering of cranes, minimum change of habitat, decrease of human disturbance and stable food maintenance would be needed in Cheolwon area.
