본 연구의 목적은 강원도 양양지역에 분포하는 소나무림을 대상으로 지상부 바이오매스와 수관층 연료특성에 대하여 분석하고자 하였다. 연구대상지는 강원도 양양군 현남면 하월천리 일대 소나무림으로 선정하였으며, 총 13본의 표본목을 벌채하여 분석하였다. 본 연구 결과에 의하면, 양양지역 소나무림의 줄기밀도(g·cm-3)는 0.347~0.409, 지상부 바이오매스 확장계수는 1.251~1.419의 범위로 나타났다. 지상부 연료량은 총 161.6 Mg·ha-1로 나타났으며, 줄기 126.4 Mg·ha-1, 가지 29.3 Mg·ha-1, 잎 5.9 Mg·ha-1로 나타났다. 수관층 연료특성 인자에 관한 연구에서는 수관화 확산 시 연소될 수 있는 연소가능 연료(잎~1 cm이하 가지)의 비율은 45.2%로 나타났고, 연료량을 수관체적으로 나눈 연소가능 연료밀도(kg·m-3)는 평균 0.178로 나타났다. 본 연구의 결과는 소나무림의 바이오매스 및 탄소 흡수량 추정과 수관화 위험성을 연료적 관점에서 평가하는데 있어 유용한 기초자료가 될 것으로 사료된다. The objective of this study was to analyze the above-ground biomass and crown fuel characteristics of Pinus densiflora stands in Yangyang, Gangwon province. A total of thirteen representative trees were destructively sampled in Yangyang region. The results showed that the stem density (g·cm-3) was 0.347~0.409, whereas the above-ground biomass expansion factors ranged from 1.251~1.419. In terms of crown fuel biomass, the above-ground biomass was 161.6 Mg·ha-1 while the stem biomass, branch biomass and needle biomass were 126.4 Mg·ha-1, 29.3 Mg·ha-1 and 5.9 Mg·ha-1, respectively. Needles and twigs with less than 1 cm diameter accounted 45.2% of the total crown fuel load. The available crown bulk density, which was calculated by dividing the crown fuel load to the crown volume, was 0.178 kg·m-3. The results of this study on the biomass and carbon stocks estimation of the Pinus densiflora together with the crown fire hazard assessment based on crown fuel loads are very significant information for the forest managers.

Group occupational health service programme started in 1990 is one of the measures to cope with limited human and financial resources in occupational health. The programme has expanded rapidly to include 52 institutions, private as well as public, all over the country. In spite of its potential impact on health of employees and practice of occupational health in small and medium sized industries, comprehensive evaluation in terms of quality has not been tried. This study has aims to develop the criteria to assess the quality of newly developed group occupational health service programme, and to investigate the quality of institutions, and finally to develop policies for the quality improvement. 1) Criteria development : By defining occupational health services, in particular for small and medium sized industries, as one of the primary health care, followings are included as core elements of qualitative occupational health programme; accessibility, continuity, comprehensiveness, technical quality, intersectoral collaboration, emphasis on preventive services, community participation, and adequacy. Again each element is divided into five major components of national health system infrastructure developed by the World Health Organization; development of health resources, organized arrangement of resources, delivery of health care, economic support, and management. In turn, each component is categorized into three aspects of quality assessment, structure, process and outcome. Expert panel selected several criteria for each category to evaluate the programme. Criteria were modified according to each group of interviewees, to produce two sets of questionnaire, one for chief operating officer and another for nurses in the institutions, and the chief operating officer and workers in the workplace. 2) Subject : Of all 52 institutions, 25 voluntarily participated in the survey. At individual institution, chief operating officer and practicing nurses were interviewed in depth. After intensive education for interviewees, every interviewees, every interview was performed with standardized guideline and questionnaire. The quality of the 'Group occupational health service programme' was found to be lower than expected. Especially in continuity, comprehensiveness, technical quality, community participation and adequacy, lower quality in structural aspect was commonly identified throughout all the institutions,. Quality in terms of accessibility and continuity highly varied among institutions., To improve quality of the programme, more comprehensive and systematic programme such as accreditation has to be introduced. In addition, human resources, governmental fund and information systems for individual workers are to be developed. As a long range plan, integration of occupational health services into the national health systems and pooling of financial resources and planned allocation should be considered.

It is known that there appear some nonspecific and delicate changes in neuropsychiatric aspect on the workers when they are exposed for a long period to low concentrated organic solvents in the work places. Therefore, it gives rise to the necessity of developing a program for the health supervisor stationed in the work place to supervise these neurobehavioral health affection. In addition to the questionnaire posed to the workers exposed to organic solvents, the study team conducted NCTB(Neurobehavioral Core Test Battery) respectively on an exposed group and a non-exposed group to organic solvents. The study team compared the results and decided whether or not to apply the results to the evaluation program of health affection. The study team divided 132 workers in 6 car repairing factories and 2 textile printing factories into exposed group and non-exposed group, pairing them off into 66 research objects according to their age, sex, and job. Neurobehavioral test was conducted on 6 items, except the POMS test, of NCTB developed by the World Health Organization(WHO). The study team conducted examinations of working environment on the exposed and non-exposed groups of each work place. The analysis of the collected materials for examinations were conducted with GC-MS. The concentration of the mixture in the air, relative to their respective threshold limit values(TLV) was calculated according to the formula of the ACGIH and the Korean threshold limits. The results indicated that for two of eight factories samples the recommended concentration limits for mixtures was exceeded. Of the six tests, the 'digit span forward', 'digit span backward' and 'digit symbol' produced conspicuous statistical differences between the two groups(p<0.1) as a result of compairing the test values by means of paired t-test. The results of respective analysis of the car repairing factories and textile printing factories revealed that the textile printing factories had greater differences between the exposed and the non-exposed than in the car repairing factories. It is presumably because the textile printing workers are continuously exposed to the organic solvents during working hours, whereas the car repairing workers are exposed only when they are doing painting works, The NCTB is assessed very useful in examining the neurobehavioral health affection under the exposure to organic solvents, and, therefore, the study team expects that the NCTB will play an important part in the course of developing a health program for the workers exposed to organic solvents.

Purpose : Ureteral stent is commonly used after ureterscopic stone removal(URS). However, there is no definitive clinical criteria in inserting the ureteral stent after URS. Patients often complain of bladder irritative symptoms, hematuria. flank pain and additive endoscopic prodedure is neces-sary to remove the ureteral stent. Therefore, we studied the clinical epicacy of selective ureteral stenting only when it is required. Materials and Methods : Of the patients who was taken URS, the following patients were exclu-ded from stent insertion ; 1) Patients who have mild hydronephrosis or symptoms less than 1week. 2) Patients who were able to insert the ureteroscope through the ureteral orifice without difficulty. 3) Patients who hardly have ureteral mucosal damage seen through the ureteroscopic field after the removal of ureteral stone. 4) Patients who did not need the additional lithoclast during the remo-val of ureteral stone. Other than the above patients and those with stones above the mid-ureter, a 6Fr. ureteral stent was inserted and kept for 3weeks. There were 29 unstented patients and 38 stented patients. Results : The average age of the non-stenting and stenting group were 37.5years old and 39.7years old and the average stone size were 0.68cm and 0.80cm. The average operation time was 3 minutes in the non-stenting and 8minutes(including ureteral stent insertion time) in the stenting group. Hos-pital stay was 3days in both groups. Intermittent gross hematuria and irritative symptoms of the bladder was shown for 3weeks after operation in most of the patients(32cases, 84.2%) of the sten-ting group while those in the unstenting group, the symptoms were relieved after2days after operation. Although mild flank pain was shown in few patients(4cases, 13.8%) of the non-stenting group, severe pain requiring intravenous analgesics was not seen in both groups. There were no specific findings in the intravenous urography which was done at 6weeks after operation, and no hematuria and pyuria was found in both groups. Conclusion : The selective placement of ureteral stent following the ureteroscopic removal of stone did not bring specfic complications. We believe that ureteral stent insertion will minimize the inconvenience especially in patients who need to return to their everyday living immediately after operation. Thus ureteral stent insertion should be used in limited situations. 요관경하배석술 후 많은 경우에 있어서 요관부목을 유치하고 잇지만 선별적으로 판단하여 설치할 경우 특별한 문제점이 없었으며, 수술 수 바로 일상생활에 복귀하여야 하는 환자들의 불편함을 최소화할 수 잇을 것으로 생각되며, 요관부목 설치는 제한적인 상황하에서 시행되어야 할 것으로 사료된다.

To know the drugs effect on gene expression and its regulating mechanism by RT-PCR and southern blot hybridization assay based on detection of the P30 gene encoding the major surface antigen, P30 of Toxoplasma gondii and the DNA synthesis in T. gondii infected HeLa cells. The experiment was performed and the results were as follows. 1. The thymidine incooperation in DNA of HeLa cell and T. gondii infected HeLa cell reached peak level at 36 hours and suddenly decreased at 48 hours. The uracil incooperation in DNA of T. gondii reached peak level at 48 hours. 2. The decrease of P30 gene expression began from 24 hours after pyrimethamine treated and 36 hours after methotrexate treated in T. gondii. The results were some what different. Pyrimethamine was more sensitive and acted earlier to T. gondii than Methotrexate did. The decrease of P30 gene expression of T. gondii was regulated these drugs in dose dependent manner. 3. The effects of dibutyryl cyclic AMP on P30 gene expression increased peak at 24 hours and on contrary decreased at 60 hours after treatment in dose dependent manner, but at 10mM high concentration of dibutyryl cAMP, P30 gene expression was supressed. 4. Actinomycine D supressed the P30 gene expression of T. gondii in HeLa cell. As the results, we presume pyrimethamine acts more powerful and earlier to supresses P30 gene expression than methotrexate, and it is regulated at transcription level. The results of RT-PCR were in agreement with that of southern blot hybridization.
