The dynamic mechanical properties of carboxylated polysulfone ionomers were studied by using DMTA. It was found that at 25 mol% of ions, the ionomer shows two glass transitions: one at ca. 200 ℃ and the other at ca. 235 ℃. It was also found that with increasing an ion content to ca. 37 mol%, a matrix T_(g) shifts to ca. 210 ℃, but a cluster T_(g) remains at the same temperature; however, the sizes of tan δ peaks for each transitions do not change with the ion content. This result means that even at those high ion contents, there is sufficient amount of a unclustered material in the samples, and the increase in the ion content does not increase the volume fraction of a cluster phase. In addition, the difference in two T_(g)s of this ionomer system was found to be ca. 40 ℃, which is smaller than that in poly(styrene-co-methacrylate) ionomer system. This finding implies that in the polysulfone ionomers weak ionic interactions in a multiplet resulting from steric hindrance due to the bulkiness of benzene ring to which the ionic group is attached and the tension on polymer chains surrounding the multiplet due to chain rigidity affect the size and stability of the multiplet significantly.

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)

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.

crp* 유전자가 도입된 대장균 MK2001(crp, cya::km)을 숙주로 사용하여 mal 유전자 발현을 촉진시키는 유전자의 하나인 sfs1(sugar fermentation stimulation)의 구조해석 결과에 의하면, 잠정적인 sfs1의 promoter영역에는 CRP단백질과의 결합영역으로 보이는 염기배열이 존재하였다. 본 실험에서는 sfs1 유전자의 cAMP-CRP에 의한 발현 조절을 확인하고자, lacZ와의 융합 유전자를 작성하였다. 작성된 융합 유전자는 cya결손주인 TP2010에서 cAMP의 첨가에 의해 B-galactosidase 활성이 크게 증가하였으며, Western blotting의 실험에서도 같은 결과를 나타냈다. in vivo에서 발현이 확인된 전사산물은 cAMP에 의해 전사 촉진이 일어났으며, CRP의 결합부위로 예상되는 DNA영역은 cAMP가 존재하면 CRP단백질과 결합하는 특성을 나타내었다. 이상의 결과로 보아, sfs1 유전자의 발현은 cAMP-CRP에 의한 전사촉진 현상을 받는 것으로 나타났다. We have cloned several E. coli sfs genes which stimulate mal gene expression with ??. One the sfs genes(pPVC2) was sequenced and potential CRP binding site is located in the upstream of the putative promoter in the regulatry region. In order to investigate the regulation of the sfs1 gene by the cAMP-CRP complex, we have constructed the sfs-lacZ fusion gene in this research. The overall transcriptional stimulations of sfs1 gene in the presence cAMP were confirmed by B-galactosidase activity and Western blot analysis of sfs1-lacZ fusion gene. Transcriptional regulation by cAMP-CRP was also confirmed by Northern blot analysis. End-labelled DNA of the DNA fragement in sfs1 regulatory region were used for gel retardation assay to examine the CRP-DNA complex in the presence of cAMP. Results here indicate that CRP binding site in the regulatory region of sfs1 gene is positive regulator for the expression of sfs1 gene.

sfs(sugar fermentation stimulation) 유전자는 crp*¹이 도입된 MK2001 균주에서 mal 유전자의 발현을 촉진시키는 특성으로서 클로닝 되어졌다. sfs4 유전자의 발현은 두 개의 promoter에 의하여 조절되어진다. 본 연구는 이들 두 promoter (P₁과 P₂)의 cAMP-CRP에 의한 발현조절을 보고자 조절영역과 CRP 결합영역에 변이가 도입된 DNA가 in vitro transcription 방법에 의해 확인되어졌다. 두 개의 promoter가 공존시에는 cAMP에 의한 P₂의 전사는 촉진되어졌으며, P₁의 전사는 억제되어졌다. P₂만이 존재할 때에도 전사는 cAMP에 의하여 촉진되어졌다. CRP 결합부위에서의 변이는 cAMP에 의한 전사촉진이 크게 감소하였다. sfs7 (nlp) 유전자의 전사산물을 확인하였으며, 이는 cAMP에 의한 발현조절을 받지 않았다. sfs(sugar fermentation stimulation) genes are involved in regulation of mal gene expression with the altered crp*¹ gene. Expression of the sfs4 gene appeared to be regulated by a two promoters. In this research, the cAMP-CRP dependent regulation of P₁ and P₂ promoter of sfs4 was examined by in vitro transcription using the regulatory region and mutated DNA of the CRP binding region. The transcription of sfs4 from P₂ is stimulated, but P₁ was totally repressed by in vitro transcription. In mutant in the CRP binding region, the effect of activation by cAMP was severely reduced. The transcript of sfs7(nlp) was identified and regulation by cAMP was not observed at the mRNA level.

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.

In this study, we analyzed the characteristics of atmospheric stability to investigate local environment change at an atomic power plant in Gori region. The used data was obtained from field observation of major meteorological variables such as wind direction and speed, air temperature, relative humidity, and solar radiation using AWS (Automatic Weather System) in Gori region from February to September in 2003. As a result, when strong northerly winds (more than 4~6 m/s) and weak northwesterly winds (2~3m/s) blow, atmospheric stability was neutral and stable from winter to spring, respectively. Atmospheric stability (neutral) in summer was similar to that in two other seasons (winter and spring), but it was stable for weak southwesterly winds (2~3 m/s). Finally, atmospheric stability was neutral for strong winds (over 4~6 m/s) in fall without respect to wind direction, while that was stable for very weak winds (less than 2 m/s).
