본 연구에서는 유기 단열재인 poly isocyanurate foam (PIR), poly urethane foam (PUR), phenol foam (PF)을 선정하여 ISO 5660-1의 기준에 따라 콘칼로리미터(cone calorimeter)를 이용하여 측정하였다. 화재위험성 평가를 표준화하기 위하여 기준물질(PMMA)을 사용하여 Chung’s equations-III와 Chung's equation-IV에 의한 화재위험성을 등급화하여 평가하였다. Chung’s equations-II의 화재성능지수-II 값은 PF가 14.77 s²/kW로 화재성능지수-II가 가장 높았고, PUR이 0.08 s²/kW로 화재성능지수-II가 가장 낮았다. 화재성장지수-II 값은 PF가 0.01 kW/s²로 화재성장지수-II가 가장 낮았고, PUR 이 1.14 kW/s²로 화재성장지수-II가 가장 높았다. Chung’s equations-III의 화재성능지수-III에서 PUR이 0.11로 화재성능 지수-III가 가장 낮게 나타났고, PF가 20.23으로 화재성능지수-III가 가장 높았다. FGI-III에서는 PUR이 14.25로 화재성장지수-III가 가장 높게 나타났고, PF가 0.13으로 가장 안전한 물질로 판단하였다. 그리고 Chung’s equation-IV의 화재위험성지수-IV는 PUR (130.03) >> PIR (19.13) > PMMA (1.00) > PF (0.01)의 순서로 나타났다. 따라서 PF가 화재위험성이 가장 낮고, PUR이 가장 높은 것으로 판단하였다. In this study, poly isocyanurate foam (PIR), poly urethane foam (PUR), and phenol foam (PF) of organic insulation materials were selected, and investigated using a cone calorimeter, as per ISO 5660-1. Standard materials (PMMA) were used to standardize the fire hazard assessment, and the fire risk was classified and evaluated by Chung’s equations-III and IV. The fire performance index-II value of Chung’s equations-II was the highest value with PF of 14.77 s²/kW. And the PUR was 0.08 s²/kW, the lowest value of fire performance index-II value. The fire growth index-II value was the lowest value with PF of 0.01 kW/s². And the PUR was 1.14 kW/s², the highest value of fire growth index-II value. The fire performance index-III (FPI-III) of Chung’s equations-III had the lowest value for PUR (0.11) and the highest for PF (20.23). The PUR showed the highest value of the fire growth index-III (FGI-III) as 14.25, while the PF exhibited 0.13 regarded as the safest materials. The fire risk index-IV (FRI-IV) value of Chung’s equation-IV was in the following order: PUR (130.03) >> PIR (19.13) > PMMA (1.00) > PF (0.01). Therefore, it was concluded that the fire risk associated with PF is the lowest, whereas that associated with PUR is the highest.

'-이나'와 '-도'의 의미론 : 분류사구와 결합하는 경우를 중심으로

This paper concerns the syntactic, semantic, prosodic, and pragmatic differences that Classifier Phrase(CLP)-ina and CLP-to display in Korean. We first characterize the syntactic-semantic differences between CLP-ina and CLP-to in positive/negative sentences, after/before-clauses, and their relative order in a negative sentence. Further we note the two reveal different scope behavior with other scope bearing elements: e.g., CLP-ina has scope over the negation or the comparative operator, while CLP-to has scope under these operators. To account for these, the paper analyzes CLP-to as a negative polarity expression and CLP-ina as a positive polarity expression. As a positive polarity expression, CLP-ina is interpreted as a focus and receives a focal accent. In contrast, as a negative polarity expression, CLP-to is interpreted as a presupositional or topical element in the discourse and does not receive a focal accent. Extending the claim of Lee, Chung, and Nam's (2000), we claim that both CLP-ina and CLP-to denote a lower bound in the likelihood scale that is pragmatically determined in the discourse context.

Adolescent Psychiatry has brief history both in its systemic study and also in its clinical practice. During past several years, it was impressed that there were increasing number and growing concerns in the field of adolesdent psychiatry in korea. In this paper, the author attempted to draw out the current state of adolescent neuropsychiatric practice in Chsun university hospital. One hundred twenty five adolescent in-patients who admitted in the department of neuropsychiatry of Chosun university, during the period from Jan. 1st 1973, until December 31th 1975, were analyzed statistically in terms of age and sex, diagnogis, educational status, reason for discharge, duration in hospitalization and medication in diagnotic categories. The results were as follows : 1) Sex distribution of study group was composed of 52% of male and 48% of female. and in diagnotic categories, as 2 whole peak age of all in-patients was between 18-25 year old(54.4% of the study group) 2) Schizophrenia was the most common initial diagnosis(41.6% of the study) 3) In diagnostic categories of these in-patients, as to the sex distribution was revealed that schizophrenia was highest rate in female patient and adolscent depression was highest rate in male patient among the cases of neuropsychiatric problems, in conversion hystery and hysterical psychosis, female patients had a higher rate than male patients. 4) The diagnosis of schizophrenia was most common at age of late adolescence. 5) Their educational level revealed that 67.5% of the patients were high school and 12.8% of the patients were college graduates. 6) As to the consideration G f medication in diagnostic categories, generally speaking, combined drug medication was performed in nearly two thirds of cases, but of case was single medication. Among the cases of schizophrenia with medicational therapy, single major tranquilizer was highest rate of 34.6%, especially among the cases of schizophrenia, major tranquilizer combined antidepressants was rate of 28.8% extremely rate. We hope the obtained results will de helpful the further clinical research of adolescent psychopathology and disorders in Chun-Nam area.

Kim Choon Min, Chang Nam Kee and Chung Whan Ho: Decomposition rate of plant residue and the vertical distibution of mineral nutrients in the woodland soil. The relationship between decomposition rate of litter and the amount of mineral nutrients dispersed to the soil horizons were studied on the oak and pine forest stand. The results are as follows: 1. Decomposition rate of litter was highest in the F horizon of the oak stand, however in the pine stand it was highest in H horizon. 2. The correlation coefficients between decomposition rate and humus, organic carbon, moisture content, calcium, phosphorus, and nitrogen in the pine stand are; 0.90, 0.98, 0.76, 0.98, and 0.88, in oak stand; 0.97, 0.93, 0.92, 0.97, 0.74 and 0.73. 3. Factors which affect the decomposition rate of litter are humus, organic carbon, moisture content, calcium, phosphorus and nitrogen. 4. Among the variables, PH, moisture content and phosphorus under the oak and pine forest showed significant differences in each horizon. 5. C/N ratio of pine stands is higher than that of oak stands studied. 6. The vertical distribution of mineral nutrients is highly related with the amount of humus accumulated on top soil.
