Four temples were picked from the central northern area in Chung-Won Zone. And the considered result of the temple scape factors can be conclusion as follows: 1. Most of relics worthy of the buddhist culture and tradition were burnt away and lost out,. There were much difficulties in collection and comparision of bibliographical materials. So urgent is the task of recovering and restoring the relics into their original forms and conditions. 2. When Chung-Won Zone in taken in a view of the military strategic position throughout the ancient triple dynasties rather than a center of cultural creation in the context of historical research, we cannot say that Chung-Won Zone was affected uniquely by a particular one nation among the three dynasties. 3. Virgin forest is completly damaged in general throughout current forest aspect of the each temple and yet forests are reviving and on the way of transition to the original. 4. It is assumed that the plants from the primitive around the temple in common were hard wood forest of mixed forest. To quickly bring up the progress of stable forest growth and development for the purpose of ecological advantage, useful hard wood forest should be well tended in a positive approach as the hard wood forest is potentially surfacing out. 5. Country species which is afforested to be proper to form the temple scape should be planted at many small sized spots so barren lands around. It is recommendable that Quercus aliena BL. stands espceally at the Kakyoon Temple be taken care of concentrating it should be leaded to the balanced selection forest type. 6. Caution should be directed to prevent damage of Theodiplosis Japonensis U. et I. from pinus densiflora S. et Z. stands at Kooin Temple and Konglim Temple and also from pinus densiflora for. multicaulis U. at Kayoon Temple. 7. Forest outside the boundary of the temple should be established as a special protective zone and worning boards should be displayed to the public so that people recognize the forest scapes are the most precious resources and dense forest should be developed to be a model forest in Korea. 8. We should be able to find a place of sight pleasue, rest and recreation through further successful development of natural scape elements surrounding the temples. It is ideal that man can expect to enjoy our mental recuperation in the nature from of the forest.

殷載淳,이중원,黃甲洙 又石大學校 1990 論文集 Vol.12 No.-
The pharmacological effects of Sarcodon aspratus extract were investigated. The extract promoted contraction of isolated stomach and ileum, and this contraction was blocked by atropine(7×10^-7M) and cyproheptadine (1.5×10^-7M). The maximum effective dose of the extract was 1.5×10^-3g/㎖. The extract promoted the peristaltic movement of small intestine, and this movement was blocked by atropine. The extract accelerated the secretion of histamine in serum and gastric acid. The serum glucose and total cholesterol levels in alloxan-induced mice were significantly decreased by oral administration of the extract for 7 days. The pharmacological effects of the extract on the central nervous system were little.

Background and Purposes: Over the past three decades, numerous studies performed in Korea have reported that job stress is a determinant risk factor for chronic diseases and work disability. Every society has its own culture and occupational climate particular to their organizations, and hence experiences different occupational stress. An occupational stress measurement tool therefore needs to be developed to estimate it objectively. The purpose of this study is to develop and standardize the Korean Occupational Stress Scale (KOSS) which is considered to be unique and specific occupational stressors in Korean employees. Subjects and Methods: Data were obtained from the National Study for Development and Standardization of Occupational Stress (NSDSOS Project: 2002-2004). A total of 12,631 employees from a nationwide sample proportional to the Korean Standard Industrial Classification and the Korean Standard Occupational Classification were administered. The KOSS was developed for 2 years (2002-2004). In the first year, we collected 255 items from the most popular job stress measurement tools such as JCQ, ERI, NIOSH and OSI, and 44 items derived from the a qualitative study (depth interview). Forty-three items of KOSS, in the second year, were retained for use in the final version of the KOSS by using Delphi and factor analysis. Items were scored using conventional 1-2-3-4 Likert scores for the response categories. Results: We developed eight subscales by using factor analysis and validation process: physical environment (3 items), job demand (8 items), insufficient job control (5 items), interpersonal conflict (4 items), job insecurity (6 items), organizational system (7 items), lack of reward (6 items), and occupational climate (4 items). Together they explained 50.0% of total variance. Internal consistency alpha scores were ranged from 0.51 to 0.82. Twenty-four items of the short form of the KOSS (KOSS-SF) were also developed to estimate job stress in the work setting. Because the levels of the subscales of occupational stress were gender dependent, gender-specific standard norms for both the 43-item full version and the 24-item short form using a quartile for the subscales of KOSS were presented. Conclusion: The results of this study suggest that KOSS might be an appropriate measurement scale to estimate occupational stress of Korean employees. Further and more detailed study needs to be conducted to improve the validity of this scale.

Staphylococcus aureus의 增殖과 enterotoxin産生에 미치는 pH, 溫度 및 食品添加物의 影響
Gab Soo Chung(鄭甲洙),Ryun Bin Tak(卓鍊斌) 한국예방수의학회 1993 예방수의학회지 Vol.17 No.1
In this study, field isolates of Staphylococcus aureus from the fresh chicken carcasses and from the pathological lesions of chickens with staphylococcosis were subjected to determine the growth characteristics and the immunological toxin types. In addition, effective food additives were screened to inhibit the growth and enterotoxin production of S. aureus in order to promote the food safety. When one hundred and twenty fresh chicken carcasses obtained from 6 poultry processing plants at Kyong-gi area from March to November in 1990 and chicken specimens diagnosed as staphylococcosis during 4 years from 1989 to 1992 were examined, total of 83 and 106 strains of S. aureus isolated, respectively. Among those, 4 of 83 isolates from the fresh chicken carcasses, and 74 of 106 strains from chickens with staphylococcosis were typed as enterotoxigenic strains of S. aureus, respectively. All these enterotoxigenic strains produced an enterotoxin type D only, and these enterotoxins from the 48 strains tested all caused an emetic response in cat. To determine the production of staphylococcal enterotoxin, 10 isolates and 4 reference strains(ATCC 13565, 14458, 19095 and 23235) of S. aureus were inoculated into NZ-medium at a concentration of 10⁴ cells/ml and incubated at various temperature. At 10℃, all fourteen strains did not grow and produce enterotoxins until 240 hours. At 15℃, 3 strains(ATCC 13565, 14458 and 1 isolate) produced an enterotoxin after 72 hours of incubation, and 8 strains(ATCC 23235 and 7 isolates) produced after 96 hours of incubation, respectively. Nevertheless the remaining 3 strains(ATCC 19095 and 2 isolates) did not produce unitl 96 hours. At 37℃, eleven out of 14 strains produced enterotoxin after 4 to 7 hours of incubation, and each 1 strain produced after 8, 9 and 10 hours, respectively. When ground chicken meats inoculated with S. aureus were incubated at 22℃, all 14 strains produced enterotoxin in the raw meat after 24 hours of incubation, and 12 strains produced enterotoxin in the heated meat(100℃, 30 minutes) after 6 to 12 hours. When 21 food additives were tested for inhibitory effects on the growth and enterotoxin production of S. aureus in brain heart infusion broth, butyl p-hydroxybenzoate(BH), butylated hydroxyanisole(BHA) and lactic acid(LA) showed a significant inhibitory effects. The lower pH of media, the greater inhibiotry effects of BH, BHA and LA were observed. In addition, a combination of BH or BHA with NaCI had a greater inhibitory effect than when either BH or BHA were used alone. Complete inhibition of S. aureus growth occured in BHI broth with 156.3ppm BH or 200ppm BHA. In combination with 2% NaCI, however, 100ppm BH or 150ppm BHA exerted bacteriocidal effects. The bacteriocidal effect was also observed when 0.4% LA was supplemented in the culture medium. When 0.2% LA, 0.2% sorbic acid, 25ppm BH+2% NaCI, 25ppm BHA+2% NaCI, or 0.15% erythorbic acid+0.26% potassium sorbate+0.01% sodium nitrite+2% NaCI were added to raw chicken meat production of enterotoxin from the inoculated S. aureus was completely inhibited until 48 hours of storage at 22℃.

9 patients with spasticity of cerebral or spinal cord origin have been maintained for upto 2 months with intermittent bolus spinal intrathecal infusion of baclofen. Prior to treatment, all of patients had severe rigidity in extremties & had frequent & extensive spontaneous spasms, all of which greatly interfered with their activities of daily living. Oral antispasmodic medications were ineffective. Within days of intrathecal baclofen infusion, the muscle tone was reduced remarkably & spasms were eliminated. The greatest benefits to the patients were improvement in activities of daily living & better sleep due to reduced spasms. Complications were not observed.
