The purpose of this study is to investigate the prime factors that affect to user postoccupancy evaluation of activities and facilities in urban parks, to classify those factors, to find out factors about them, and then to suggest important indicators in the urban park planning, design, and development. The survey research was done using the self-administered questionnaire method by 435 peoples in the Busan City who participated in recreational activities in the Amnam Park. The Analysis of the data primarily consists of two phase: The first analysis was dealt an exploratory factor analysis which identified major factors involved in user postoccupancy evaluation with reacreational activities and facilities in Amnam Park by the SPSS(Ver.6.0) program and the second analysis was used to investigate the factors affected to user postoccupancy evaluation in the urban park by the Regression Analysis. According to the factor analysis, user postoccupancy evaluation of facilities in urban parks concerning the 20 variables, 5 prime factors by the staistical values were considered. The factor analysis showed that user postoccupancy evaluation of activities in urban parks concerning the 11 variables, 3 prime factors by the staistical values were analysed. Postoccupancy evaluation in the urban park by the Regression Analysis suggested that the two varlables as 'the directions of park development' and 'companies with the personal specific characteristics' are significant in addition to the some variables presented in user postoccupancy evaluation with reacreational activities and facilities in Amnam Park by the factor analysis. Furthomore the analysis models were identified as having significant effects on the factor and regression analysis. Overall fits of both models were very good. These significant relationships indicate important factors and variables that should be considered in planning, design, and development of the urban parks. Therefore, development direction of the h a m park has to be analyzed as significant factors concerning user postoccupancy evaluation in a systematic way, recognized as important variables for planning process. The urban park has to be fully designed and established in the planning process not by the decision-maker's subjective evaluation but by user postoccupancy evaluation.

This paper presents a reliability-based topology optimization (RBTO) using bi-directional evolutionary structural optimization (BESO). An actual design involves uncertain conditions such as material property, operational load and dimensional variation. Deterministic topology optimization (DTO) is obtained without considering of uncertainties related to the uncertainty parameters. However, the RBTO can consider the uncertainty variables because it has the probabilistic constraints. In this paper, the reliability index approach (RIA) is adopted to evaluate the probabilistic constraint. RBTO based on BESO starting from various design domains produces a similar optimal topology each other. Numerical examples are presented to compare the DTO with the RBTO.

In this study, plant regeneration through in vitro culture from plantlet stems of Yooja (C. junos Sieb.) and trifoliate orange (P. trifoliata Rafin.) was attempted to make mass-production system of virus-free plants having the same genotype with mother plant. In order to investigate physiological change depending on the developmental stage of plant regeneration, the changes of total protein, peroxidase and esterase activity and their isozyme patterns as well were examined in 1/2 MS medium. The results are as follows : 1. The MS medium for the optimal callus induction and shoot formation was utilized. The medium was supplemented either with 2,4-D and Kinetin or with BA and NAA. The optimal concentrations were the combination of 1.0mg/ 2,4-D +0.3mg/ Kinetin and 1.0mg BA +0.3mg NAA in callus induction and shoot formation, respectively. 2. For the plant regeneration from somatic embryos, 1/2 MS medium was used with supplements of growth regulators (free, 1.0mg/ IBA +1.0mg/ BA ,0.5mg/ IBA +0.5mg/ BA). Shooting and rooting were the best in the treatment of 0.5mg/ IBA and 0.5mg/ BA combination. 3. The total protein content has a tendency of increase with the developmental stage of embryo, but it was decreased at the plantlet. Also it was the highest at 8 and 6 weeks stage in C. junos Sieb. and P. trioliata Rafin, respectively. In the SDS-PAGE pattern of protein, C. junos Sieb. showed bands of 29.0 and 40kDa at 10 weeks. The 45,66 and 97.4 kDa bands at 10 weeks of culture were shown in P. trifoliata Rafin. 4. The highest esterase activity was shown at the 6 and 8 weeks of culture in C.junos Sieb. and P. trifoliata Rafin.., respectively. 5. Esterase isozyme patterns were shown difference according to the developmental stage. In C. junos Sieb. a new band was observed at pl 7.7 following 4 weeks culture. On the other hand, new bands in P. trifoliata Rafin. were observed at pl 7.5~6.5 following 4 and 6 weeks culture, respectively.

Purpose: The gastrointestinal (GI) tract is the most common site of extranodal non-Hodgkin's lymphoma (NHL), which is increasing in incidence, but there is no established optimal treatment modality. Thus, this study was investigated the clinicohistologic feature, the therapeutic modalities, and the prognosis for GI-NHL, as well as the factors affecting it. Methods: We retrospectively analyzed 45 patients who had been diagnosed as having GI-NHL and had been followed up from July 1994 to February 2005 at Soonchunhyang University Hospital. The patients were divided into groups according to the site of origin and to various other features, and the survivals of the various groups were compared. The modified Ann Arbor system and WHO classification were adopted for staging and histopathologic classification, respectively. Results: GI-NHL of the stomach, small bowel, ileocecal region, and colon occurred in 28 patients (62.2%), 5 patients (11.1%), 3 patients (6.7%), and 8 patients (17.8%), respectively, In one patient, the entire gastrointestinal tract was diffusely involved. The median age of patients was b5 years (25~78 years), and male-to-female ratio was 1:1.1. Fourteen patients were in stage Ⅰ, 24 in stage Ⅱ, 4 in stage Ⅲ, and 3 in stage Ⅳ. Surgical resection was performed in 19 patients, and combination chemotherapy was performed in 43 patients. Surgical resection only was performed in 4 patients, Chemotherapy only was performed in 26 patients. The expected overall 5 year survival of 45 patients was 39.6%, and there was a significant survival difference between the stages, but between sites of origin (p=0.842). The most important factors influencing the survival was the stage and other factors were not significant. Conclusion: The stomach was the most common site of GI-NHL. Most GI-NHL were localized Stage was the most important prognostic factor. However, Prospective randomized studies are needed to approve the therapeutic modality.

This paper is based on an experiment analysing the stress corrosion cracking behaviour of welding specimens compared to that of non-welding specimens of STS 304 HP stainless steel in corrosion solution. As a corrosion condition, stainless steel has been known to be the most fragile in a solution of 42% MgCl₂heated to the boiling point, therefore the experiment was carried out in this condition. The experiment was carried out with argon gas TIG welding specimens and non-welding ones made of stainless steel plates, thickness 2mm, by tensile force. At this time, the tensile force was taken to be the value of the yield strength of the tensile test specimens divided by the safety factor of 3.0 to 3.5, 4.0, 4.5, and 5.0. In this paper, the relations between Time of Initial Crack, Time of Failure, Time of Final Fracture and Crack Propagation Length were investigated and then plotted. Furthermore, the relations between Stress Intensity Factor K proposed by Irwin and the Time of Initial Crack, the Time of Failure, the Time of Final Fracture were calculated and plotted. At the last, all the relations plotted were expressed to normal equations by computer, and the equations were used to analyse the data obtained in the experiment. The conclusions obtained in this study are as follows: 1. Welding materials, compared with non-welding ones, as the Time of Initial Crack, the Time of Failure, and the Time of Final Fracture were generally very fast, appeared to be a phenomenon of unstable brittleness fracture. 2. Non-welding materials, compared with welding ones, as the safety factor was larger or the working stress was smaller, appeared to be a phenomenon that the longer had had greater durability. Therefor, welding materials must be considered enough to be used in heate affected and stress corrosion atmosphere. 3. The normal equations of the Time of Initial Crack and the variation rate to the same Stress Intensity Factor K are as follows: (A) Non-welding T =259702.4-5451.2 K+28.386 K² T = -5451.2+28.386 K (B) Welding T= -332.693+28.043 K-0.211 K² T' =28.043-0.211 K here, T; Time of Initial Crack, T'; Variation Rate of Time of Initial Crack to Stress Intensity Factor K, K ; Stress Intensity Factor.

Background: The purpose of this study was to document the incidence and clinical characteristics of patients with tuberculosis (TB) in combat and auxiliary police, living in a group, in Korea where the incidence rate of active TB in a general population is higher than in Western countries. Materials and Methods:We retrospectively reviewed the medical records of all tuberculosis patients diagnosed at National Police Hospital from January 2002 through December 2004. Results:In 2002-2004, a total of 156 cases of tuberculosis were identified with the mean (Standard deviation) age of 20.6 (±1.0) years. Of these, 134 (85.9%) patients were registered as new cases, 11 (7.1%) as relapse, 2 (1.3%) as failure, 5 (3.1%) as treatment-after-default cases whereas 4 (2.6 %) patients were not included in any categories. Average annual new TB rate and smear-positive TB rate were 86.5/10^(5) and 17.4/10^(5) person-years, respectively. In 12 of 31 smear-positive cases, time from onset of symptoms to diagnosis was more than 30 days. Two multidrug-resistance TB cases were identified and two suspected outbreak episodes of TB had occurred during 3 years. Conclusion:There was no statistically significant difference in the incidence rate of new cases of TB between the general population aged 20 to 29 years and combat and auxiliary police in Korea. 배경 : 국내 결핵의 발생은 감소 추세에 있으나 여전히 후진국형 발생양상을 보이고 있다. 특히 집단생활을 하는 젊은이들에서 발생하는 결핵의 유행이 간헐적으로 알려지고 있어 우려를 낳고 있다. 이에 저자들은 최근 전경대원의 결핵 발병 양상에 대해 알아보고자 본 연구를 시행하였다. 재료 및 방법 : 2002년 1월부터 2004년 12월까지 3년간 경찰병원에서 결핵 진료를 받은 전경대원의 의무기록을 후향적으로 분석하여 연도별 결핵 신환발생률, 도말양성결핵 신환율, 진단 지연, 집단발병, 다제내성결핵을 조사하였다. 결과 : 연도별 결핵 신환자 수(10만명당 발생추정치)는 2002년 50명(83.6명), 2003년 42명(83.7명), 2004년 42명(93.5명)이었고 도말양성 폐결핵 신환자 수는 2002년 10명(16.7명), 2003년 11명(21.9명), 2004년 6명(13.4명)이었다. 3년간 도말양성 폐결핵 환자는 31명이 있었고 그 중 12명은 호흡기 증상 발생 30일이 지나서 진단을 받았다. 다제내성 결핵은 2명이 있었으며 결핵의 집단발병이 의심되는 사례는 2차례 있었다. 결론 : 전경대원과 20-29세 연령군 일반인의 결핵 신환발생률, 도말양성 폐결핵 발생률의 통계적으로 유의한 차이는 없었다.
