This study aimed at an evaluation of the reliability and validity of Ewha Defense Mechanism Test(EDMT) for standardization during the period from June 25 to July 10 with nationalwide sample which was standardized by Rhee Kun Hoo. Kin Jae Un. Kim Jung Kyu. and Park Young Sook. The number of subjects were 1.323 who were sampled by the method of proportional stratification on age. sex. education. local area variables. This test is composed of 20 defense mechanism subscales and total items of the test are 200. The results were as follows : 1) The range of means of each scales were from 2.70 to 3.34 and the range of items standard deviation was from .71 to 1.28. 2) The corrected item-total correlation coefficients were than .10 for all items except two items which was the index of internal consistancy. 3) The spearman-Brown split-half reliability coefficients were more than .66 and the retest reliability coefficients were more than .72 for all scales. 4) By the evaluation of the cross validation with “16 Personality Factor Inventory”. it was found that 11 factors were consistent with expectation among 16 factors so that the result of cross validity was moderately sufficient. 5) By the factor analysis. four factors were extracted. Factor 1 was “unstable sensitization defense mechanisms”which were acting out, displacement, somatization. dissociation. projection. and passive-aggressive behavior. Factor 2 was “ego-expansive defense mechanisms” which were composed of controlling. distortion. altruism. humor. and sublimation. Factor 3 was “ego-denial defense mechanisms” which were reaction formation. bragging identification. and regressin. Factor 4 was “reality evasive defense mechanisms” which were denial rationalization. suppression. anticipation. and evasion.

반응온도가 증가할수록 Brand별 철광석의 환원율은 증가하였으며 일정반응온도에서 원광석형태인 Romeral 보다 펠렛형태인 CVRD,IOC 및 ALG 시편의 환원율이 더 높음을 알수 있었고 펠레시편 중 IOC가 타 시편에 비해 환원율이 가장 큼을 알 수 있었다. 수소가스에 의한 원광석 및 펠렛시편의 환원반응에서 전반응속도는 계면화학반응에 의해 율속됨을 알 수 있었으며, 활성화에너지값은 Romeral, CVRD, IOC 및 ALG의 경우 각각 약 4.8, 7.7, 4.5 및 5.3kcal/mol이었다. 이들 활성화에너지값으로부터 수소가스에 의한 환원반응은 펠렛형인 IOC가 가장 우수함을 알 수 있었다. In order to get an fundamental data to select a suitable ore brand for hydrogen reduction, the reaction kinetics of hydrogen for ore brands was investigated. Four kinds of ore brands such as Romeral ore, CVRD, IOC,ALG pellet were selected for this experiment. It was observed that the reduction ratio of pellets was higher than ore and IOC pellet showed the highest in comparing with other pellets. The kinetics data was fitted to [1-(1-R)1/3] = kt for surface reaction control. The activation energy for the reduction of Romeral, CVRD, IOC and ALG were 4.8, 7.7, 4.5 and 5.3 kcal/mol respectively. It was shown that the overall reduction rate was controlled by surface reaction. And also, we can get result that IOC was the most suitable ore for the reduction with hydrogen gas among the specimens

Pancreatic cystadenoma is very rare, slow growing tumor and generally preoperative differential diagnosis may be difficult. A 43-year-old female was admitted to our hospital with the complaint of abdominal discomfort in the epigastrium for about preceeding 5 years. Ultrasonography and Computed tomography were performed. When endoscopic retrograde cholangio-pancreatogram was performed, displacement of distal pancreatic duct by huge mass was noted and injected dye was drained irregulary into the cavity of mass. Distal pancreatectomy was performed with splenectomy. The mass size of distal pancreas was 7X4cm, and the cyst contained with yellowish thick mucoid fluid. Diagnosis was confirmed the mutinous cystadenoma of the pancreas on histologic examination.

An increasing frequency of methicillin resistant S. aureus(MRSA), methicillin resistant coagulase negative staphylococci(MRCNS) and Enterococcal infection have been observed in recent years. Teicoplanin is a new glycopeptide antibiotic obstained from the Actinoplanes teicomycetius. The molecular structure and spectrum of antimicrobial activity of teicoplanin is simillar to those of vancomycin, and has been reported to have an excellent in vitro and in vivo effect against various gram-positive infections. Therefore, we evaluated the in vitor susceptibility of gram positive cocci, such as, S. aureus, coagulase negative Staphylococci(CNS), and Enterococci to teicoplanin and vancomycin. The total 253 strains consisted of MSSA(40), MRSA(53), MSCNS(47), MRCNS(48), and Enterococci(65). They were assayed by disc diffusion and agar dilution. During the study, 57% of S. aureus and 49% of CNS showed resistance to methicillin. The inhibitory diameter of teicoplanin was 15-20mm in MSSA, 12-19mm in MRSA, 13-24mm in MSCNS, 11-23mm in MRCNS, and 15-22mm in Enterococci respectively, and showed sensitivity in all but 8 strains(3.2%). The range of the minimum inhibitory concentration (MIC) of teicoplanin to MSSA, MRSA, MSCNS, MRCNS and Enterococci were 9.12-2.0㎍/ml, 0.25-2.0㎍/ml, & 0.25-32㎍/ml, 0.12-1.0㎍/ml respectively. One case of S. haemolyticus was resistant to teicoplanin (32㎍/ml) by the agar dilution method. Eight minor (3.2%) and one major(0.4%) error was observed when the MIC and disk diffusion data were correlated with teicoplanin. As for vancomycin the inhibitory diameter was 17-21mm in MSSA, 15-21mm in MRSA, 18-26mm in MSCNS, 18-25mm in MRCNS, and 16-22mm in Enterococci respectively. The range of the MIC of vancomycin to MSSA, MRSA, MSCNS, MRCNS, and Enterococci were 0.25-1.0㎍/ml, 0.25-4.0㎍/ml, 0.5-2.0㎍/ml and 0.5-2.0㎍/ml respectively. One minor error (0.4%) was seen with the vancomycin disk. The MIC90 of MSSA and MRSA exhibited the same results in teicoplanin (1.0㎍/ml, 1.0㎍/ml), and vancomycin(2.0㎍/ml, 2.0㎍/ml). MSCNS and MRCNS exhibited greater MIC90 with teicoplanin(4.0㎍/ml, 8.0㎍/ml) than vancomycin(2.0㎍/ml, 2.0㎍/ml). Incontrase Enterococci were more susceptible to teicoplanin(0.5㎍/ml) than to vancomucin (2.0㎍/ml). Results from this analysis indicated that both teicoplanin and vancomycin were very excellent for gram positive infections, especially those resistant to methicillin.

C_(1)-HVOCs 제거를 위한 Ru-Sn/γ-Al_(2)O_(3) 촉매 제조 및 반응성 평가

HVOCs 제거에 사용되는 백금-팔라듐계보다 저렴한 촉매 개발을 목적으로 다양한 루테늄계 촉매를 제도하여 C_(1)-HVOCs 분해 특성 평가 실험을 수행하였다. 그 결과 Ru[2]-Sn[2]/γ-Al_(2)O_(3) 촉매가 가장 우수한 성능을 보였다. 구조 증진제인 주석은 흡착 산소의 양을 증가시키고, 다양한 산소 이온 종의 생성에 기여함을 알 수 있었다. HVOCs 분해 반응에 첨가되는 산소 원자는 주로 루테늄과 주석에 흡착되며, CH_(3) 등 HVOCs는 지지체인 γ-Al_(2)O_(3)의 브뢴스테드 및 루이스 산점에 흡착됨을 알 수 있었다. 흡착된 HVOCs의 염소와 브뢴스테드 산점의 수소 화학 결합에 의한 HCl의 생성 반응이 HVOCs 분해의 주 반응 기구임을 알 수 있었다. Various ruthenium(Ru) based catalysts, which were less expensive than Pt-Pd based catalysts, were prepared and their activity with C_(1)-HVOCs(Halogenated Volatile Organic Compounds) was evaluated. Ru[2]-Sn[2]/γ-Al_(2)O_(3) was found to have the most desirable effect on the destruction of HVOCs. Tin taken as a structural promoter was found to increase the amount of oxygen adsorption and to generate various oxygen ions. Oxygen atoms were found to be mainly adsorbed on the surface of ruthenium and tin and HVOCs such as CH_(3)Cl to adsorbed on Bronsted and Lewis acid sites of γ-Al_(3)O_(3) supports. It was found that the formation of HCl by the reaction of chlorine in HVOCs with hydrogen atom on Bronsted acid site was the main reaction mechanism in the destruction of HVOCs.

The purpose of this study is aiming at understanding the behavior of broiler growers in collecting information about broiler price in Korea. In order to achieve the goals questionnaires collected from 61 broiler growers during May 1995 were analyzed. The respondents' demographic data were summarized as 45 year-old, high school graduated and 11 year-experienced broiler growers. Their average farm size was 24,125 heads with 4.1times turnover per year, and annual income was 25.4 million won(U$32,000). The main sources of the information about price were magazines(38.3%) and seminar organized by Korean Poultry Association(29.8%). Seventy seven percent(77.0%) of the respondents replied that they had information about price, which was published(44.3%) and self collected(29.5%). The respondents regarded past price and feed production amount as the main factors affecting future broiler price. The respondents pointed out that the fluctuated broiler price, unfairness in selling their products and damage by disease were the main problems to be solved in their farming. Consequently, it would be an important task to provide a price forecasting devices using personal computers in the future.

To investigate the effect of alcohol drinking on the absence pattern, we conducted survey for 606 male workers who employed at the small & medium sized manufacturing factories located in Taejon city and Chungnam region. The following results were obtained. Among the variables, age, marrital status, body mass index, smoking, working hours per day, and working climate showed significant realtionship with the alcohol drinking times. Gross absence days and sickness absence days showed significant relation with alcohol drinking frequency, but non-sickness absence days did not showed any relation with alcohol drinking frequency. After adjusting the variables which had significnat relation with absence days and alcohol drinking, there were still significant relation between absence days and alcohol drinking frequency.
