Sasang Industrial Complex and hinter-residential areas caused some problems related to the infrastructures and environmental pollution in lack of some considerations from the land subdivision project. According to the Pusan Urban Masterplan(1992) and the Pusan-Kyungnam Metropolitan Development Plan(1995), then, the surveyed area will be redeveloped to the western core of the Pusan Metropolitan City and attracted to the mixed land-use complex with the commercial and distribution function, including the electricity, shoes, leports, and clothes wholesales. This results of the survey found that most subjects considered the environmental pollution as serious and the unsatisfactory factors were as follows: traffic jam and air pollution. According to whether you know the Complex Transferred Plan, 34.9% of them was responded to "yes" and the rest to "no". This finding means that the area is environmentally bad condition in terms of the transportation and infrastructures, however, most subjects were satisfied with the location because of easy access to the CBD. The results also suggested that the redevelopment of the area is needed and the way is mainly based on the individual improved construction.

The critical power(CP) is the highest intensity to sustain for a long time without a fatigue. The anaerobic work capacity(AWC) is the highest anaerobic capacity to be provided by anaerobic energy system without the infection of hypoxia. The purpose of this study was to determine the relationship between AWC and AnP and to verify the validity of AWC. The subjects were consisted of 10 elementary and 10 middle school male students(12.8±1.3yrs, 159.3±12.1㎝, 49.4±11.8㎏). The critical power and anaerobic work capacity were calculated by work-time relationship after four cycle ergometry test to fatigue from 1 to 10 minute. The anaerobic power included Margaria-Kalmen test, Sargent jump and Wingate test. The main finding were as follows. The AWC of elementary and middle school students. were 6.47±2.63KJ and 11.10±3.01KJ. The AWC of elementary students was 58.3% of the middle school students's one. The AnP of elementary students were 47.2∼66.5% of the middle school students's one. And there were high correlation between AWC and AnP(0.64∼0.87, P<0.01). This study showed that AWC is useful index on AnP both elementary and middle school students.

정성호,양규호,이태희 대한소아치과학회 2001 大韓小兒齒科學會誌 Vol.28 No.1

Rubinstein-Tabyi syndrome은 드물게 나타나는 기형증후군으로 정신 발달지연, 넓은 손가락과 발가락, 작은 키, 특징적인 안모등의 증상들을 주증상으로 하는 여러 계통의 형태이상이 비 특정 양상으로 나타나는 선천적 증후군이다. 1963년 Rubinstein과 Tabyi에 의해 처음 보고된 이 증후군은 많은 연구에도 불구하고 명확한 원인이 알려져 있지 않고 있으며, 1990년 이후 Rubinstein-Tabyi syndrome에 대한 특정소인 연구에서 이 증후군의 임상적 특징을 보이는 소수의 환자에게서 16번 염색체의 16p13.3의 유전학적 단절이 보고되었다. 그러나, 이 증후군의 특정병인으로 보기는 힘들고, 여전히 이 증후군의 진단에는 특징적인 임상증상들로 인해 가능하다. 이 증후군의 치과적 증상으로는 높게 위치한 구개, 소하악증, 다발성 우식증 등이 보고되고 있다. 다발성 우식증을 주소로 내원한 6세 5개월된 남아가 넓은 엄지손가락과 발가락, 정신 및 운동발달지연과 안검하수증, 이상 형태의 귀 등을 포함하는 안면부 이상 등의 증상들을 보였다. 저자들은 환자가 보이는 특징적인 임상 증상들로 인해 Rubinstein-Tabyi syndrome으로 진단을 내리고 환자의 전신 상태를 고려하여 모든 치과 치료를 전신마취 하에 시행하였다. Rubinstein-Tabyi syndrome(RTS) is a congenital multisystem dysmorphic syndrome with many non-specific features, making diagnosis occasionally difficult. The major features of this syndrome include mental retardation, characteristic facial appearance, short stature, microcephaly, and broad thumbs and halluces. This syndrome was first described by Rubinstein and Tabyi in 1963, and many studies have been continued about this syndrome, but specific pathogenesis of the Rubinstein-Tabyi syndrome phenotype is still not clear. High arched palate, micrognathia and multiple caries etc have been reported in Rubinstein-Tabyi syndrome. In this report, a 6-year and 5-month-old boy visited at our department due to multiple dental caries, who showed broad thumbs, mental and physical development retardation, and characteristic facial appearance including both ptosis and ear deformity. This patient was diagnosed as a Rubinstein-Tabyi syndrome, and treated the multiple dental caries under general anesthesia. This study was aimed to observe the relationship between medical and dental characteristics.

The purpose of this study was to investigate the effects of detraining and retraining on serum lipid and hormones in soccer players. Subjects were seven male high-school soccer players. V˙O_2max was determined for each subjects by administering a treadmill test(initial speed: 90m/min, grade: 5%, increasing speed per 3 min: 30m/min). Serum lipid(T-C, TG, HDL-C LDL-C) and hormones(epinephrine, norepinephrine, growth hormones, cortisol) were assayed pre and post detraining in 10, 20, 30 days after retraining. The repeated ANOVA was used to determine significant differences. The 0.05 level of significance was as critical level for the study. The results of the study were as follows: 1. V˙O_2max(ml/min) were 3576.3±204.2ml/min pre detraining, 3234.1±198.9 ml/min post detraining. There are significant(p<.05) difference between pre and post detraining. In 10, 20, 30 days after retraining, V˙O_2max(ml/min) were 3601.4±170.9 ml/min. There were significantly(p<.05) increased in retraining periods. 2. V˙O_2max(ml/kg/min) were significantly(p<.05) decreased from 62.3±2.9 ml/kg/min to 55.9±4.7 ml/kg/min in detraining. In 10, 20, 30 days after retraining, V˙O_2max(ml/kg/min) were 62.4±3.4ml/kg/min, 62.7±2.3ml.kg/min, 67.3±7.2ml/kg/min respectively. There were significantly(p<.05) increased in retraining periods. 3. T-C were significantly (p<.05) increased from 166.6±8.5mg/dl to 175.3±10.3 mg/dl in detraining. In 10, 20, 30 days after retraining, T-C were 160.1± 3.2mg/dl, 156.7±3.7mg/dl, 140.3±9.0mg/dl. There were significantly(p<.05) decreased in retraining periods. 4. HDL-C were 61.4±6.6mg/di pre detraining, 5.3±6.6mg/dl post detraining. There are significant(p<.05) difference between pre and post detraining. In 10, 20, 30 days after retraining, HDL-C were 56.9±7.1mg/dl, 56.4±9.2mg/dl, 57.7±9.1mg/dl respectively. There were no significant difference in retraining periods. 5. The hormones(epinephrine. norepinephrine, growth hormone, cortisol) were changed as same patterns. Epinephrine were 26.0±7.0[g/ml pre detraining, 24.6±3.2pg/ml post detraining. In 10, 20, 30 days after retraining, epinephrine were 26.9±5.6pg/ml, 30.6±6.2pg/ml, 29.4±5.6pg/ml respectively. There were no significant difference in retraining periods. In conclusion, HDL-C, epinephrine, norepinephrine, growth hormone and cortisol were decreased, T-C, LDL-C and TG were increased in detraining. But HDL-C, epinephrine, norepinephrine, growth hormone and cortisol were increased, T-C, LDL-C and TG were decreased in retraining.

The cell mediated immune response appears to result from the specific recognition of an antigen. by T lymphocytes. It has been well recognized that T cell play an important roles in the induction of tuberculin hypersensitivity and immunity to tuberculosis. In order to evaluate effect on T lymphocyte proliferative response to purified 30-kDa antigen from Mycobacterium tuberculosis, stimulation effects of peripheral blood lymphocytes with 30-kDa antigen, crude antigen and PHA were measured by MTT colorimetric assay. Three groups of healthy subjects, representing PPD(+), PPD() and PPD(-) persons, were investigated. The proliferative response to 30-kDa antigen were elicited the plateau at concentration of 20 to 0.1㎍/ml, crude antigen showed rapid reduction as decreasing the concentration of antigen, for the PPD(+) person. Both antigens, at concentration of <1㎍/ml, failed to stimulate lymphocytes of the PPD(-) person. Therefore the concentration of 30-kDa antigen to induce optimal stimulation was 1㎍/ml. The lymphocyte proliferation to 30-kDa antigen and crude antigen were significantly increased in PPD(+) group when compared to those in PPD(-) group, but PHA response was no significant difference. These results suggest that 30-kDa antigen could stimulate lymphocyte from PPD(+) population and MTT colorimetric assay could be applied to assess proliferative response of lymphocyte.

Objectives : This study is to investigate the hypothesis that schizophrenic patients have difficulty in inferring mental state of others. Methods : Twenty schizophrenic patients and twenty normal subjects were administered to the Cartoon Task required inferring the character's intention in a given context. Results : The schizophrenic patients showed a statistically significant impairment in the Cartoon Task. Both groups chose the card depicting a frequent everyday action significantly more rather than the similar card to the last picture in each story for wrong answers. Conclusion : These preliminary results suggest that schizophrenia is associated with a specific deficit of the cognitive ability referred to as social cognition, and this deficit can be detected not only in the acute phase as found in previous research studies, but also in remission. Also when subjects fail to appreciate what is going on in the minds of other people, they seem to rely on a socially familiar experience.

The 30 and 32 kDa antigens from Mycobacterium tuberculosis H37Rv culture filtrates, identified as biologically important proteins in the immune responses against mycobacterial infection, were purified and used in enzyme linked ummunosorbent assay (ELISA) for the determination in specific IgG and IgM levels in cerebrospinal fluids of 15 patients with tuberculous meningitis and 17 controls with nontuberculous diseases. High reactivity to both antigens was observed in tuberculous meningitis. Mean IgG and IgM antibody levels differed significantly (P < 0.001) between patients and con trols. Mean IgG antibody levels were also higher than IgM levels in tuberculous meningitis. A comparison of the antibody levels against the 30 and 32 kDa antigen within the tuberculous meningitis patients showed higher IgG reactivity to the 30 kDa than to the 32 kDa antigen, suggesting that the antibody response of these patients is directed predominantly against the 30 kDa protein. However, the patterns of reactivity to 30/32 kDa, 30 kDa and 32 kDa antigen in individual subjects were similar. By the cut-off value adding 2 stsndard deviation to the mean absorbance of controls, the sensitivity and specificity of the IgG antibody to the 30 kDa antigen were 100% and 94.4%, respectively. These values were higher than those obtained by 30/ 32 kDa and 32 kDa antigen. From the above results, it is suggested that the 30 kDa antigen may be dominant antigen and more valuable in the diagnosis of tuberculous meningitis than 32 kDa antigen.

Cell-mediated immunity is necessary for protection against Mycobacterium tuberculosis. T lymphocytes are thought to play a central role in cell-mediated immune response. And in vitro stimulation of leukocytes with mycobactria or their products induces synthesis and release of several cytokines, including IL-2. To study the T lymphocyte proliferative response to purified 30 kDa antigen from Mycobacterium tuberculosis H37Rv, IL-2 or their combination, peripheral blood lymphocytes and mononuclear cells isolated from healthy subjects were stimulated with the 30 kDa antigen, IL-2 or both. The proliferations of lymphocytes and molnonuclear cells to 30 kDa or 30/32 kDa antigen were significantly increased in PPD(+) group when compared to those in PPD(-) group. It is confirmed here that have shown synergy between 30 kDa antigen and IL-2(250U) in the induction of lymphocytes and mononuclear cells proliferation in PPD(+) group. The proliferative response reflects synergy between two separate activation stimuli. And macrophage-like cells existed in peripheral blood mononuclear cells were shown to help the synergy of the proliferative response to mycobacterial antigen and IL-2. The proliferative responses of lymphocytes and mononuclear cells to 30 kDa antigen were more increased than those to 30/32 kDa antigen. So it was suggested that 30 kDa antigen was the more immunogenic antigen than 30/32 kDa antigen.

Many researchers have interested ruthenium complexes due to their similarity and difference in chemical properties. In this study, [Ru(phen)_2LPEI]^2+ complex was synthesized by the reaction of [Ru(phen)_2Cl_2] with polymeric amine ligands, namely, linear poly(ethyleneimine)(LPEI). [Ru(phen)_2LPEI]^2+ complexes were analyzed by NMR, UV/VIS, and MS spectrometry. as well as Elemental analysis. From NMR analysis, [Ru(phen)_2LPEI]^2+ complexes were confirmed by comparison of [Ru(phen)_2Cl_2] with LPEI complexes. Coordination of LPEI ligands to [Ru(phen)_2Cl_2] showed absorption at 480㎚, whereas [Ru(phen)_2Cl_2] complex alone has a peak at 370㎚. Mass of LPEI complexes was analyzed 1638 and 1898 dalton, [Ru(phen)_2LPEI]^2+ complex form MS spectrometry. The spectroscopic methods for the [Ru(phen)_2LPEI]^2+ complexes system revealed that two nitrogen donor atoms on the LPEI chain are coordinated to the [Ru(phen)_2Cl_2] complex.
