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.

Objective: Yang Geouk San Hwa - Tang (YGSHT) has been widely used in Sasang Constitutional Medicine of Korea for treatment of acute inflammatory symptom, such as palatine tonsillitis, polydipsia, headache, papule, pimple however, the mechanism of its anti-inflammatory activity has not been clarified. In this study, therefore, we investigated the mechanism of the inhibitory effect of YGSHT on LPS-induced inflammation. Materials and methods: The effect of YGSHT was analyzed by ELISA, RT-PCR and Western blotting in LPS-stimulated RAW264.7 cells. Results: We found that YGSHT suppressed not only the production of pre-inflammatory cytokines (IL-$1{\beta}$ and TNF-$\alpha$), the generation of nitric oxide (NO) and prostaglandin E (PGE)2, but also the mRNA expression of pre-inflammatory cytokines, inducible nitric oxide synthase (iNOS), and cyclooxygenase (COX)-2. Furthermore, YGSHT was shown to inhibit the phosphorylation of ERK1/2 and JNK1/2 and the activation and translocation of NF-kB from cytosol to nuclear in LPS-stimulated RAW264.7 cells. Conclusions: These results suggest that YGSHT exerts an anti-inflammatory effect through the regulation of the ERK1/2 and JNK1/2 pathway and NF-kB pathway, thereby decreasing production of pre-inflammatory cytokines, NO, and PGE2.

The ν_6 band of the ethane gas molecule was theoretically synthesized. The intensity and the frequency of each rotational line were computed with VAX-11 computer. The theoretically synthesized spectrum was compared with the experimentally obtained spectrum, which was taken through FT-IR spectrophotometer MX-3600. The R and P branches of the ν_6 band contour of the ethane gas molecule were different from the regular symmetrie top molecule and rather similar to the linear molecules as if there were no K dependence. The absorbance of the P-branch spectrum was overlapped by the unknown branches of the neighbour bands The intensities and frequencies of the unknown lines were not indentified. The overall band contour of the observed spectrum was quite well coincided with the theoretical spectrum except the P-branch.

Changes of peripheral arterial oxygen saturation(SaO_2) were compared according to the methods of extubation after general anesthesia in 44 pediatric patients in TaeJon ST.Mary's Hospital between March and May in 1992. Patients were divided in two groups. Group Ⅰ (n=22); endotracheal extubation was performed with suctioning by catheter after one or two endotracheal suctions. Group Ⅱ (n=22); endotracheal extubation was performed wit positive pressure administration of 100% oxygen by reservoir bag simultaneously after one or two endotracheal suctions. All patients were administered 100% oxygen for one minute after extubation and transferred to recovery room and administered oxygen 3ℓ/min by face mask for three minutes. The results are as follow: 1) SaO_2 was decreased significantly (p<0.05) after extubation in group Ⅰ compared with control and group Ⅱ. 2) The number of patients whose SaO²bellow 95% are increased in group Ⅰ(77%) compared group Ⅱ(5%) after endotracheal extubation. 3) SaO_2 of all patients were recovered to over 99% after administration of oxygen for three minutes in recovery room.

In order to investigate the variation [of cervical mucus patterns which were expected to change in the estrous cycle or various estrous stages, cervical mucus was taken front the uterine cervix (external os) of 19 heads of non-pregnant dairy cows. Observations were made on the characteristic patterns in cervical mucus smears which were influenced by estrus and anestrus status in the estrous cycle. The conclusions obtained were as follows : 1. The fern-like crystalization was a characteristic sign in cervical mucus smears in the estrus period. 2. If was observed the fern-like crystallization began to appear at the proestrous stages and it remained clearly until the first 5th day of the estrous cycle. At the 6th day, the larger fern-like crystals changed into small "palm-leaves" like crystals or in some cases they were almost disappeared. The crystallizations were completely lost to view and they were transformed into cloudy form from the 7th to 16th day of the anestrous period. 3. The value of cytology of cervical mucus smears was not particular.

地方化時代의 到來로 高揚市는 많은 變化가 豫想되고 있다. 1980年부터 繼續的으로 論議되던 地方自治의 問題가 지금은 現實化되어 1991年 4月에는 基礎地方自治의 議會를 構成하고 6月에는 廣域自治團體의 議會를 構成하였고 머지않은 將來 에 地方自治團體의 長을 選出할 豫定이다. 앞으로 많은 施行錯誤가 있을 수 있겠으나 地方自治時代에 돌입한 것은 누구 도 否認 할 수 없는 사실이다. 1997年경의 住民構成은 1990年代初期의 高揚市에 居住하고 있던 原住民과 一山을 포함한 新高揚 開發地域에 90萬의 新 入住者로 구성될 것이며, 이러한 高揚市 住民構成의 變化는 地方自治에 커다란 衝擊要因으로 작용될 것이다. 新.原住民의 要求를 調和하는 問題는 여러 形態로 나타날 수 있으나 住民福祉라는 側面이 매우 강하게 대두될 것이다. 高揚市의 福祉活動은 生活保護者들을 위한 특수한 경우를 제외하고는 거의 전무한 상태이다. 地方自治制度가 어느정도 安定的인 국면으로 접어들면, 地域的 次元에서 市民 모두를 위한 福祉活動이 深度있게 展開되어야 할 것이다. 市行政機 關과 市議會는 兒童福祉, 婦女福祉, 老人福祉및 醫療福祉에 대한 現況울 把握하고 이에 대한 해결의 優先順位를 결정하 여 다가오는 人口의 增加에 따른 福祉需要를 충족시켜 나가야 할 것이다. 福祉需要에 대한 優先順位를 硏究者들이 제시하여 보면 託兒施設과 더불어 綜合病院施設을 擴充하여 市民들에게 奉仕 하는 태세를 體系化하여야 할 것이며 그밖에는 施設을 擴充하는 方式보다는 年齡과 性別 및 職業 등의 基準에 맞게 "프 로그램"을 積極的으로 開發하는 努力이 경주되어야 할 것이다. 그러으로써 量的인 意味에서 뿐만이 아니라 質的인 意味 에서 福祉活動을 展開할 수 있는 基盤을 造成할 수 있을 것이다. It is expected that Koyang City have lots of changes according to the emergence of Decentralization era. Nowdays local self-government has been realized since its disscussion in 1980. On april, 1991, the assembly of basic self-government was established, and the assembly of extensive self-government constructed on june, 1991. The chairman of local-government assembly is supposed to be elected in the new future. None can deny the beginning of local-government era inspite of potential trial and errors. Population structure in 1997 is expected to be composed of the existing civilians of Koyang City in early 1990's and about 0.90millions of new comers in new cities including llsan area, and he change of the city population will significant impacts on the self-government scheme of Koyang City. The problem to coordinate desires of existing civilians and that of new comers might be embodied in many kinds of aspects, but welfare-raising will be strengthed first of all. Existing welfare programme of Koyang City dosen't show any signigicant activities except the case of Green Card programme. It is desirable that whole-sideed welfare programme be perfomed by local levels in the stage of staionary self-government systems. Administrative institutions and assembly of city should survey and research the present situations of children welfare, female welfare, the old age welfare, and medical welfare, and decide their priorities to meet increasing desires coming from rapid increase of city-population. We, researchers, propose several outstanding problems by priority as follows; to expand medical institutions and public nursery schools accompanies by strenthening the attitude of government employees for public service, to develop various programmes in order to activate many exiting institutions more efficiently rather than to build new institutions needed, in consideration of ages, sex and occupations of their users. If these propositions accomplished the welfare programme will have cornerstone to enrich its activities as well as activities as well as enlarge it bounderies.

A numerical study was performed to investigate characteristics of one-dimensional consolidation of soft clay. Results of consolidation tests with the remolded normally consolidation clay of having a very high initial void ratio were analyzed by using the numerical technique of finite difference method based on the finite strain consolidation theory, to evaluate consolidational characteristics of soft clay under surcharges on the top of clay. On the other hand, a numerical parametric study on soft clay consolidated due to its self-weight was also carried out to find its effect on one-dimensional consolidation. Terzaghi's conventional consolidation theory, finite strain consolidation theories with linear and non-linear interpolation of effective stress-void ratio -permeability realtion were used to analyze the test results and their results were compared to each other to figure out the difference between them.Therefore, the validity of theories was assessed.

현무암을 콘크리트 골재로 이용하여, 환경오염 방지와 에너지 절감 효과를 얻을 수 있다. 반요인실험법을 사용하여 현무암을 굵은골재에 일정한 비율로 치환한 콘크리트의 최적배합설계 제시를 위한 예비 실험에서 현무암의 굵은골재 치환율, 물-시멘트비, 잔골재율, 슬럼프와 같은 주요 변수와 변수 사이의 2차 상관관계를 파악하였다. 예비실험을 한 결과 현무암을 굵은골재로 100%까지 치환했을 때 현무암을 혼입한 콘크리트의 강도 발현에 가장 중요한 변수는 물-시멘트비로 분석되었고, 현무암의 굵은골재 치환율은 강도 발현에 거의 영향이 없는 것으로 분석되어 현무암을 콘크리트의 굵은골재로 대체할 수 있다는 것을 알게 되었다. 변수 사이의 2차 상관관계에서는 현무암의 굵은골재 치환율과 잔골재율의 상관관계가 콘크리트의 강도 발현에 가장 큰 영향을 미치는 것으로 나타났다. 목표압축강도를 만족하는 현무암을 혼입한 콘크리트의 최적배합설계는 현무암의 굵은골재 치환율, 물-시멘트비, 잔골재율에 관하여 제시하였다. The waste basalt might be used in concrete aggregate, saving energy and protecting environment. An half-factorial experiments were performed with the primarary variable such as water-cement ratio, waste basalt substitution ratio, fine aggregate ratio and slump as a preliminary study for optimum mix design of concrete. The preliminary study show that the water-cement ratio is the most important factor to the concrete strength, followed by slump. The substitute of waste basalt up to 70% has little infulence, indicating that it can substitute the coarse aggregate without damaging the Concrete strength. The interaction between waste basalt substitution ratio and fine aggregate ratio was most significant to the concrete strength among the 2-way interaction variable. Only compressive strength affect to the formation of optimum mix design area as target compressive strengh becomes bigger. Optimum mix designs of concrete incorporating waste basalt, satisfying the target responses, were proposed in terms of waste basalt substitution ratio, water-cement ratio and fine aggregate ratio.

Adsorption equilibrium of heavy metals ion on the peat moss was confirmed Frundlich isotherm Removal efficiency of heavy metals ion was increased from pH 2 to 10 and heavy metal removal efficiency was increased in the sequence of Cu(Ⅱ) > Pb(Ⅱ) > Cd(Ⅱ) > Mn(Ⅱ) on the PM(Peat Moss). The PM is likely to be more effective adsorption than the PAC to removal of metal ions in the solution, since PM's weakly acidic functional groups which is not founded on the PAC, in addition to its high surface area and porosity. But, the PM is not separated from the solution water by sedimentation process. So, a liquid and solid seperation between the PM and the solution water could be considered for the PM's field application. But peat moss was low cost adsorbent. Thus author propose to adopt PM as a adsorbent for heavy metal removal.
