The purpose of the present study was to investigate the relationships among the contact frequency of homosexual lewd materials, homophobia, and prejudice against homosexuals of adolescents. A survey was carried out to 389 middle school students in Gyeonggi province. The brief summary of the survey is as follows. First, among 389 subjects the 73.0% had contacted homosexual lewd materials during the last 1 year, and more boys than girls contacted lewd materials. Most of the subjects had watched the internet sex movies. Movies, TV shows, the papers for adults, and sexual photos were also homosexual lewd materials that many of the subjects had watched. The kinds of materials that middle school students have contacted were different based on sex. Boys contacted the internet sex movies while girls contacted fanfic most. All of them had experience to watch movies and TV shows frequently. Second, the results of regression analysis revealed that the relationship between the contact frequency of homosexual lewd materials and homophobia did not show any statistically significant correlation. However, girls showed statistically significant negative correlation between the contact frequency of homosexual materials and homophobia. Third, the results of regression analysis indicated that the relationship between the contact frequency of homosexual lewd materials and prejudice against homosexuals showed statistically significant positive correlation.

Background : Pneumocytitis cainii pneumonia (PCP) can occur in immunocompromised hosts especially such as AIDS or cancer patients. Although recent research had focused on PCP in AIDS patients, few studies have described the clinical presentations of PCP in recipients of stem cell transplantation (SCT). We evaluated the clinical manifestations of PCP in SCT patients admitted at St. Mary's hospital, Seoul, Korea. Methods : The medical records of 17 PCP patients undergoing SCT between Feb. 1998 and Feb. 2000 were reviewed. The diagnosis of PCP was confirmed through the demonstration of Pneumocytitis cainii via either cytology of brochoalveolar lavage (BAL) or histological technique of lung biopsy. CMV disease and CMV infection were confirmed by BAL culture and antigenemia respectively . Results : Seventeen patients were all recipients of allogeneic SCT and 7 of 17 patients were performed non-sibling SCT. Patients presented with symptoms including brief period (4 ∼23 days) of fever (76%), dyspnea (70%), cough (64%), and signs such as rare(58.8%), Sixteen patients (94%) had been receiving immunosuppressive agent such as cyclosporine A (64%) or Fk506 (35%) without PCP prophylaxis. Eleven patients (64%) were treated with corticosteroid with mean dose of 16 mg/day prednisolone and mean duration of 4.6 months after post-SCT period. Twelve patients were co-infected with CMV. Another co-infected miCroorganisms were Pseudomonas aeruginosa, Mycobacterium tuberculosis, herpes simplex virus, parainfluenza virus, Average duration of treatment with trimethoprim-sulfamethoxazole (TMP/SMX) was 21 ±9 days. Four patients died, and three of them were related with PCP. Conclusion : PCP developed frequently in patients who were taking immunosuppressive drug due to graft versus host disease or were not taking TMP/SMX prophylaxis. High risk patients showing fever, cough, or dyspnea should be considered to take early bronchoscopic intervention for detection of PCP. When treat for PCP, it also be considered to the possibility of coinfection such as CMV. (Korean J Infect Dis 33:273∼279, 2001)

서주연,유대황,곽진성,황윤회,김형국 부산대학교 유전체물성연구소 2004 유전체 논문집 Vol.3 No.

The adsorption of oxygen and methane on the bundles of open-ended single wall carbon nanotube(SWNT) was studied using the volumetric adsorption qst was obtained from the adsorption isotherm measurements performed at different temperatures. The trend in the values of the methane isosteric heat of adsorption showed three regions, representative of the adsorption on the different types of adsorption sites. In case of oxygen, on the other hand, such distinguishable regions were not appeared in the N-qst graph. From the results of qst the binding energies of oxygen and methane adsorbed on open-ended SWITs were estimated.

Styrene-co-lithium methacrylate ionomer의 기계적인 성질에 미치는 LiCl의 영향

나연화,김준섭,유지강,박기주 조선대학교 생산기술연구소 1999 生産技術硏究 Vol.21 No.2

The effect of LiCl salt added to styrene-co-lithium methacrylate ionomer on the mechanical properties of ionomers was studied dynamic rnschanically. When the LiCl salt was added to a 100% Li-neutralized ionomer, the amount of added salt. in the range of 100-300% to ionic groups of the ionomer, did not change the mechanical properties of the ionomers, This implies that the added salt may form isolated LiCl salt aggregates in the polymer matrix. However, when LiCl was added to a 200% neutralized ionomer, the cluster T_(g) shifted to a low temperature and then the sample started to flow. This result suggests that in this case the LiCl salts reside in and near the multiplets, resulting the weakening of ionic interactions between ionic groups in multiplets.

The dynamic mechanical properties of poly(styrene-b-isobutylene-b-styrene) and its sulfonated ionomers were investigated. The triblock copolymer showed a tan δ peak at ca. -25℃, which is ascribed to the T_(g) of polyisobutylene blocks. The copolymer also showed a shoulder on a tan δ curve at ca. 50℃, which is probably associated with crystallization and/or melting of the crystalline polyisobutylene blocks. Above 100℃, the copolymer started to flow. In the cases of ionomers, well developed rubbery plateaus, extended to ca. 150-160℃, were seen in modulus-temperature plots. A tan δ peak for the T_(g) of the polyisobutylene blocks and a shoulder peak were also observed for the tetramethylammonia neutralized sulfonated ionomer. However, the shoulder peak became smaller and shifted to low temperatures, which implies that the ionic interactions in this system reduces the ability of crystallization or/and melting of the polyisobutylene blocks. For the K neutralized ionomer sample, only a tanδ peak for the T_(g) of the isobutylene blocks was seen. This different result in these two ionomers is believed to be due to the difference in the strength of ionic interactions.

Every year, 190,000 tons of oystershell are wasted from many oyster farms. And the fact that the main components of oystershell are CaO and Al₂O₃ which are chemically similar to those of lime leaded to an assumption that oystershell can be used as raw materials for synthesizing dewatering conditioner. In this study, the Jar-Test and the Bu˝chner funnel test were proceeded for the assessment of dewaterability of a thickened sludge and digested sludge. And TTF(Time To Filter), SRF(Specific Resistence Filtration) and TS(Total Solids) were adopted as the valuation indices of sludge dewaterability. Dewatering conditioner which composed of both oystershell and loess is much dewaterable than the one composed of only oystershell. And in the course of combining of oystershell and loess, the following fact was found that the dewaterability of the combination which have the higher ratio of oystershelI than that of loess is superior. Eventually, the most suitable ratio of dewatering conditioner complex is 9 : 1 (oystershell : loess) in treating not only thickened sludge but also digested sludge. In conclusion, the conditioner synthesized from waste oystershell and loess seems to be used as a splendid alternative material for the dewatering conditioner treating the sludge of sewage.

스타이렌 아이오노머의 기계적인 성질에 미치는 혼합 양이온의 영향

The styrene-co-methacrylate ionomers neutralized with Na +, Ba2 +, and mixed cation of both were prepared. The dynamic mechanical properties of two cation-containing ionomers were measured and compared to those of the ionomers neutralized with only one type of cations. We found that in the ionomers with one type of cations the difference in the type of cation does not change the glass transition temperatures. It was found, however, that the cluster Tg of the mixed cation ionomer is lower than that of the single cation ionomers. Thus it was postulated that in the two-cation system the two cations in a solution have sufficient dynamics to form new type of multiplet containing both cations, which may be slightly bigger than that found in the single cation multiplet. The mechanical properties also imply that the strength of ion interactions in the multiplets of the two cation ionomer is thought to be weaker than that of the one cation ionomers. These two effects are believed to contribute the lower in the cluster glass transition of mixed cation system.

This study purposed to provide a scientific base for understanding the effect of therapeutic intervention using motivation on chronic stroke patients’balance and determining whether it is applicable as a new therapeutic intervention. For this study, we sampled 38 chronic stroke patients, and divided them randomly into a motivation training group(n=20) and a control group(n=18). To the control group was applied neurological physiotherapy 5 times a week, and 30 minutes each time, and to the motivation training group was applied neurological physiotherapy and then, additionally, a Nintendo Wii-Fit program 3 times a week, and 30 minutes each time. Before and after the experiment, the subjects’dynamic balance was measured with functional reach test(FRT), timed up & go test(TUG), and 10m gait test, and their static balance was measured with the Romberger Test. When dynamic balance ability was compared between before and after the experiment and between the motivation training group and the control group, significant difference was observed in the results of FRT, TUG, and 10m walking test between before and after the intervention(p<.05). As to static balance, in addition, body balance movement distance was not significantly different. Therapeutic intervention using dynamic motivation was found to be more effective than the control group in improving dynamic balance.
