Bacillus cereus KCTC 3674 produced at least two kinds of extracellular proteases. Two major bands of the protease activity with molecular weights of approximately 100 and 38 kDa were obtained after gelatin-SDS-PAGE. The production of extracellular proteases occurred during the logarithmic growth phase and was greatest when cultures reached the stationary growth phase. On the other hand, the growth of B. cereus KCTC 3674 and the production of its extracellular proteases were severely inhibited by the addition of protonophore carbonylcyanide m-chlorophenylhydrazone (CCCP). Thus, it was concluded that the growth of B. cereus KCTC 3674 and the production of its extracellular pretenses were strongly affected by a H+ electrochemical potential.

연구목적 : 본 시험의 목적은 임상시험 시작전에 연구자들을 대상으로 PANSS Workshop을 통하여 PANSS, ESRS에 대한 국내에서의 표준화 작업을 구축하고 새로운 정신병 치료제인 리스페리돈의 효과와 안정성을 재확인하여 리스페리돈 사용에 대한 적정화를 이루는데 있다. 연구방법 : 1996년 4월부터 1996년 9월까지 국내 39개 대학병원 정신과에 입원중인 혹은 증상이 악화되어 입원하는 정신분열병 환자 377명을 대상으로 다시설 개방 연구를 시행하였다. 1주일간의 약물 배설기간을 가진후, 리스페리돈을 8주간 투여하였고, 기준점, 1주, 2주, 4주, 그리고 8주후에 평가되었다. 용량은 제1일에는 리스페리돈 1mg씩 1일 2회, 제2일에는 2mg씩 1일 2회, 제3∼7일에는 3mg씩 1일 2회 투여하였다. 이후 환자의 임상상태에 따라 임의로 증량할 수 있으며, 최대 일일 16mg을 초과하지 않도록 하였다. 추체외로 증상을 조절하기 위한 투약을 허용하였다. 임상증상 및 부작용의 평가는 PANSS(Positive and Negative Syndrome Scale), CGI(Clinical Global Impression) 그리고 ESRS(Extrapyramidal Symptom Rating Scale)을 사용하였다. 연구결과 : 377명중 343명(91%)이 8주간의 연구를 완결하였다. 치료 종결시점인 8주후 PANSS 총점수가 20% 이상 호전된 경우를 약물 반응군으로 정의할때, 약물반응군은 81.3%였다. 리스페리돈에 반응하는 예측인자로는 발병연령, 이전의 입원 횟수, 유병기간이 관련 있었다. 리스페리돈은 1주후부터 PANSS양성, 음성, 및 일반정신병리 점수상에 유의한 호전을 보여 효과가 빨랐다. CGI의 경우도 기준점에 비해 1주후부터 유의한 감소를 나타내었다. ESRS의 경우, 파킨슨 평가점수는 기준점과 비교해 투여 1주, 2주, 4주후 유의하게 증가되었다가 8주후 기준점과 차이가 없었다. Dystonia 평가점수는 1주후만 유의한 증가를 보였으며, dyskinesia 평가점수는 유의한 차이가 없었다. 혈압, 맥박수의 생명징후 및 일반 혈액학 검사, 생화학적 검사, 심전도 검사에서 유의한 변화는 없었다. 결 론 : 이상의 다시설 개방 임상 연구를 통해 리스페리돈은 정신분열병 환자에서 양성증상뿐만 아니라 음성증상 및 전반적인 증상에도 효과적인 것으로 사료된다. 보다 명확한 평가를 위해서는 다른 항정신병약물과의 이중맹검 연구가 필요할 것으로 생각되며, 또한 장기적 치료에 대한 평가도 함께 이루어져야 하겠다. Objective : The purpose of this study was to investigate the efficacy and safety of risperidone in the treatment of Korean schizophrenic patients. Method : This multicenter open study included 377 schizophrenic patients drawn from 39 university hospitals. After a wash-out period of 1 week, the schizophrenic patients were treated with risperidone for 8 weeks and evaluated at 5 points ; at baseline, and 1, 2, 4 and 8 weeks of treatment. The dose was increased from 2mg/day(1mg twice daily) to 6mg/day(3mg twice daily) during the first week and adjusted to a maximum of 16mg/day over the next 7 weeks according to the patient's clinical response. Medication to control extrapyramidal symptoms was permitted. The psychiatric and neurological status of the patients was assessed by PANSS, CGI, and ESRS scales. Results : 343(91%) of 377 patients completed the 8-week trial period. Clinical improvement, as defined by a 20% or more reduction in total PANSS score at end point, was shown by 81.3% of patients. The predictors of response to risperidone were associated older age, shorter duration of illness, fewer previous hospitalization. Risperidone had rapid onset of action ; a significant decrease of the total PANSS and three PANSS factor(positive, negative, general), and CGI was already noticed at the end of first week. For the ESRS, parkinsonism rating scores were significantly increased until week 4 comparing with baseline. Dystonia rating scores were significantly increased until week 1, and dyskinesia rating scores were not significantly changed during the study. Laboratory parameters including vital sign, EKG, hematological, and biochemical values showed no significant changes during the trial. Conclusions : This study suggests that risperidone is generally safe and effective against both the positive and negative symptoms in our group of patients.

In general, it is said that every big city suffers absolute lack of parking lots. But parking lots attached to their buildings are not always used effectively, so some of them are sometimes left unoccupied. At this time, the roads around those buildings have become, surely enogh, random parking lots for the cars failing to enter the attatched parking lots. Especially in the case that the attached parking lot is a mechanical one, there is more inconvenience when vehicles are driven in and out. For this reason, the use rate of that kind of parking lot is not brisk enough. It, thus, results in the failure to maximize the effect of the investment. This paper is a study based on an actual survey. According to the result of its analysis, while many building managers say that their attatched parking lots always suffer shortage, the survey shows a different story. The parking index of the buildings completed with their mechanical parking lots is generally below 1.0. It can be inferred from the figure that there is some unoccupied space left at just the time that many cars are parked on the roads in the vicinity of those buildings. In the case of the buildings equipped with independent parking lots, the parking index shows in general the figure above 1.0. It meats that the use rate of their parking lots does not reach 100 percent. Taken altogether, it can be concluded that in reality the attached parking lots are not absolutely in need. As one of direction to improve those conditions, it is suggested that commuting cars should be limited to the occupation of their parking lots. In addition, it should be followed by the reformed regulation to control the attached parking lots in Pusan. The owners of those attatched parking lots should seek to improve their management system as well. People who use the parking lot should gradually enlighten their consciousness about it, and help nut the parking lots in a more effective way.

After measuring actual stress by two measurements(Dynamic Strain Meter, Histogram Recorder)on truss rail road bridge, we could perform time history analysis by 3-D beam element method on modelling bridge. And then,after analyzing bridge structure in static by 3-D modelling, we estimated degree of fatigue damage in main member, secondary member of tie zone,cutting area of base metal cross section for confirming the result. In case that the simulate stress is carried out on medeling bridge, most of those simulation mainly is performed by main members.But in real bridge fatigue damage problems generally caused by junctions, connections, joints in which especially local stress is activated. Therefore, in this paper actual stress on critical area was estimated through the analysis result by simulation. With this study, we can estimate the degree of fatigue damage from a safety point of view and comparative accuracy.

The diffuse sclerosing variant (DSV) is a rare malignant tumour that accounts for 0.7-5.3% of all papillary thyroid cancers. DSV tends to occur at a younger age and has a higher incidence of cervical lymph node metastases, compared with papillary thyroid carcinoma. A 62-year-old female patient diagnosed thyroid nodule with diffuse and mild increased 18F-deoxy-glucose (FDG) on FDG positron emission tomography (PET)-computed tomogram (CT) scan. The ultrasound images showed typical findings of DSV such as diffusely enlarged thyroid lobes and diffusely scattered microcalcification. We performed this patient ultrasonography guided fine needle aspiration and cytologic analysis revealed papillary carcinoma. Total thyroidectomy with central compartment node dissection and lateral lymph node dissection was performed and finally diagnosed DVS. The authors report this case with literature review.

In this paper, we predict the tracking performance and formulate the tracking parameter of the multiple hypothesis tracking filter (MHT). The MHT algorithm is known to be consistent and superior to any other tracking filters in performance. The tracking performance of the MHT algorithm is quantified in terms of its correct hypothesis probability and the false track density. The tracking performance is approximately evaluated by using the hybrid conditional average approach(HYCA).

Sasang Industrial Complex and hinter-residential areas caused some problems related to the infrastructures and environmental pollution in lack of some considerations from the land subdivision project. According to the Pusan Urban Masterplan(1992) and the Pusan-Kyungnam Metropolitan Development Plan(1995), then, the surveyed area will be redeveloped to the western core of the Pusan Metropolitan City and attracted to the mixed land-use complex with the commercial and distribution function, including the electricity, shoes, leports, and clothes wholesales. This results of the survey found that most subjects considered the environmental pollution as serious and the unsatisfactory factors were as follows: traffic jam and air pollution. According to whether you know the Complex Transferred Plan, 34.9% of them was responded to "yes" and the rest to "no". This finding means that the area is environmentally bad condition in terms of the transportation and infrastructures, however, most subjects were satisfied with the location because of easy access to the CBD. The results also suggested that the redevelopment of the area is needed and the way is mainly based on the individual improved construction.

This study examined how much consumers were satisfied and what their needs were for a coffee shop located on a university campus. Also, it was examined what factors were influencing the satisfaction of a coffee shop located on a university campus. The questionnaire survey method was conducted and 194 university students who had experiences visiting a coffee shop located on university campus in Cheongju, were selected. For the statistical analysis, descriptive analysis, factor analysis, t-test and ANOVA were used by the SPSS 14.0 program. The findings were as following: First, consumers' overall satisfaction with a coffee shop located on a university campus was near mid-point. Second, the most important factor for consumers’ satisfaction of a coffee shop on university campus were location. And, price, taste, and various product options followed. Third, consumers' needs for a coffee shop on a university campus were composed of three factors: interior circumstance, service, and attendant circumstances. The most important out of these three factors was the service factor (m=3.89). Fourth, consumers' satisfaction for the coffee shop on a university campus was composed of four factors: interior circumstance, service, ease of access, and brand loyalty. Furthermore, ease of access was found to be the most important factor (m=3.98).

Radiation treatment with gamma-rays and electron-beams was used to remove polyvinyl alcohol(PVA), one of the main components of dyeing wastewater. PVA was effectively decomposed by radiation treatment, thus the removal was near 100% at an initial PVA concentration of 44 ㎎/L. However, total organic carbon(TOC) removal was less than 5% due to lower transformation of PVA to CO₂. This directly indicates the radiation treatment alone is not appropriate for the complete decomposition of PVA. In this sense, the improvement of biodegradability(BOD_5/COD) of PVA by radiation treatment was studied. Both gamma-ray and electron-beam treatments significantly increased the biodegradability of PVA by transforming non-biodegradable PVA to biodegradable by-products. This suggests radiation treatment, especially electron-beam treatment that showed better improvement of biodegradability, can be used as a pre-treatment of biological degradation process of PVA.
