The purpose of the present study is to review theresearch literature on children's stress and thier copying styles. This literature review is organized from an ecological point of view, in that child's own characteristics as well as children's microsystem such as family school, and community factors are included. Also children's stress is viewed as a continuing process over the time span in which in individual child goes through the pocess of experiencing stressful events, of using copying strategies and, of exhibiting stressful symptoms.

A case of an unicystic ameloblastoma of the mandible presenting as an apical periodontal cyst was reported. The lesion showed an unilocular radiolucency with well delineated border Histologic examination revealed that a fibrous cyst wall with a lining that consists of partially of ameloblastic epithelium. The overlying epithelial cells are loosely cohesive and resemble stellate reticulum. The fibrous cyst wall of the cyst is infiltrated by typical follicular ameloblastoma, but devoid of inflammatory reaction in the cystic wall. Some considerations regarding differential diagnosis, pathogenesis and biologic behaviour of the lesion were discussed.

中國 社會經濟史料로서의 方志

尹源鎬 全北大學校 1985 論文集 Vol.27 No.-

Chinese local gazetteers dates as far back as the Dynasty of Tung-han. And it developed through the Dynasties of Sui and Tang with geographical characters. To Sung Dynasty, the humanities and history added to it, and all the social phenomena (such as geography and map, border, hillsand streams, famous places of scenic resort, officers, population, taxation, local products, villages, customs, personage, necromancy, bronze and tablet, literary pursuits, portent, etc.) and natural phenomena added to it. In the Dynasties of Yuan and Ming, it succeed the forms of local gazetteers of provious Dynasty. However to Ch'ing Dynasty, the movement which local gazetteers should be treated as a history was carried out by Chang Hsueh Cheng. Thenceforth, lots of local gazetteers were written ; so these are the tresury of historical materials. Chinese local gazetteers covers the diverse forms from the national to the local scale. Even though there are some differences in contents, it covers the above-mentioned basically and it became to have the materials of social economy as times pass. Therefore the materials of local gazetteers are concrete and individual in quality and wide enough to cover the whole nation. In this way, the values of local gazetteers are summarized as follows. First, local gazetteers covers the diverse materials of all the social phenemena and natural phenomena related to the above phenomena, so its capacity is superior to authentic records. Second, it is more valuable than authentic records chiefly because it covers the concrete facts of each local district. Third, the materials of local gazetteers are reliable chiefly because it was investigated, arranged and edited by the authorative experts. Finally, it has the contents which covers the lives of humbler classes so that it is plebeian. Besides the above-mentioned values, it is emphasized to be useful to study socio-ecomomic history because it is written more concretely than authentic records and China has the complexity of socio-economic history. In China, socio-eonomic phenomena is not seperated from humanitic phenomena. Especially under the comprehensiveness, rarity, reliability and plebeianism of materials in local gazetteers to collect and arrange the historic materials, and to describe the history are the efficient short-cut to study Chinese socio-economic history.

구리 이온을 함유한 XCuO · (50-X) Na2O · 50P2O5조성을 승온속도 10K/min로 900℃까지 승온한 후 1시간 동안 유지하여 용융하였으며, 연속적으로 가열되어진 흑연판에 부어 냉함으로써 모유리를 제조하였다.제조된 유리를 분말상의 시편으로 만들어 상온에서 증류수로 3일동안 용해시켰다.각각의 조성에 따른 살균효과를 측정하였으며, 제조된 시편을 소지토에 첨가하여 그 항균특성을 관찰하였다.항균특성 평가를 위하여 사용된 균주는 Staphylococcus aureus 와 Salmonella typhi가 사용되었으며, Staphylococcus aureus 균주에 대해서는 모든 시편 담지후 3시간 이후에, Salmonella typhi에 대해서는 6시간 이후에 모든 균이 소멸되는 것으로 관찰되었다.

This article intends to present the framework for social welfare policy analysis. The purpose of policy analysis is to provide heuristic aid to better problem-solving by helping to perceive policy problem, clarify objectives, investigate policy alternatives, and predict the consequences of each alternatives. Existing positivistic policy analysis, however, has serious limits, such as conflicts on fundamental values. Based on finding frame work, many of social welfare policies are more properly analyzed.

This study was to provide the fundamental data for vegetation recovery and efficient management of fire-burned forest area. For the purpose of this study, natural and artificial forests reproduced after fire burning were selected, including 7 sites of natural forests consisted of various fire-burned dates and 4 sites of artificial forests of 4 dominant tree species, Larix leptolepis, Pinus rigida, Chamaecyparis obtusa, Robinia pseudo acacia, and were investigated about species compositions and diversities. Obatained results are as follows : 1. By the community differential table the plant communities of this area are classified by Quercus acutissima - Lespedeza bicolor - Pteridium acquilinum community, Q. dentata - Pinus densiflora community, and Q. mongolica - Rododendron mucronulatum -Miscantus sinensis community centering around Quercus spp. in natural forests, and each Larix leptolepis, Pinus rigida, Chamaecyparis obtusa, Robinia pseudoacasia community consisting of species planted for the afforestation in artificial forests. 2. Natural forests are appeared to possess abundant species as the mean no. of species occured in the area are 49 species of natural forests and 39 species of artificial forests, and No. of species occured only in the natural forests and the artificial forests are 37 species and 31 species, respectively. 3. In natural forests Quercus acutissima, Quercus mongolica, and Rhododendron mucronulatum had the most high importance value in canopy layer, under layer, and shrub layer, respectively. Quercus mongolica and Rhododendron mucronulatum showed increased importance values with passing time after the fire. 4. In artificial forest, tree species that showed the most high importance value in each canopy - subtree - shrub layer were Chamaecyparis obtusa - Celtis sinensis - Deutzia parviflora in Chamaecyparis forest, Pinus rigida - Quercus acutissima - Quercus mongolica in Pinus rigica forest, Robinia pseudoacasia - Robinia pseudoacasia - Quercus serrata ini Robinia pseudoacasia forest, and Chmaecyparis obtusa - Callicarpa japonica without subtree layer in Chamaecyparis otusa forest. 5. Species diversity (H′) of natural forests was the most low value in Siljun area having the shortiest passing time after the fire, on the other hand Yumboksa area having the longgest one was the most high value and in artificial forests Larix leptolepis forest showed the most high value and Robinia pseudoacasia the most low one with the highest dominance. For species diversity of each crown layer, subtree layer in natural forests and shrub layer in artificial forest showed the most high value.

Twenty-seven bacterial colonies capable of growing on benzoate as the sole source of carbon were isolated from streamside soils. Three of isolates were found to be extremely effective in metabolizing the benzoate, when they were incubated in the basal salt medium containing 2,000ppm of benzoic acid at 30℃ for 48hrs. The three isolates, Y205, W212 and J211 were identified Pseudomonas aeruginosa, Bacillus fastidiosus, and Aeromonas sp. respectively through morphological and physiological examination. Optimal temperature and pH for benzoate degradation of the isolates appeared to be 35℃ and pH for Pseudomonas sp. Y205 and Bacillus. sp. W212, and 30℃ and pH 7.0 for Aeromonas sp. J211. The highest degradation of benzoate by the three isolates was obstained in the growth media containing ammonium sulfate as nitrogen source. Optimal concentration of ammonium sulfate was 6.0g/l for Pseudomonas sp. Y205 and Aeromonas sp. J211, and 4.0g/l for Bacillus. sp. W212. When the three isolates were cultivated in basal salt medium containing 2,000ppm benzoate under optimal condition, they showed a logarithmic phase growth 12hours and a stationary phase growth 18hours after innoculation, and the benzoate degradation of 91.15-92.40% after 72-hours incubation. Benzoate degradation increased in parallel with the cell growth.

The present study was designed to observe the age-related changes in the IL-6 production capabilities of the peritoneal macrophages. Pertioneal macrophages were collected from adult mature (13-20 weeks of age) and aged BALB/c mice (60-70 weeks of age). Macrophages were cultured in the presence of endotoxin (lipopolysaccharide lug/ml, Escherichia coli serotype 0111:B4). In aged mice, IL-6 levels in the culture supernatants were seemed to be relative high than that in adult mature mice.
