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.

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.

The seaside plaza at the Dodong-port of Ulleung-gun is cognized having characters of space. these characters are a gateway connecting to land, the image of Ulleung's symbol, cleanness as a whole and The scenery is beautiful beyond expression. But the seaside plaza be jammed up and be disordered with visitors, natives and mobiles, and then they didn't make the best use of the expressionist nature and landscape on the images of Ulleung of cleanness and pleasant. Therefore this study was to plan on the seaside plaza at the Dodong-port toward the heightening of Ulleung's symbol, identity, individuality through the presentation of images on cleanness and pleasant, and the expropriation of variety activities on the visitors and natives. The seaside plaza was designed with seven schemes those can be summarized as follows. The first was the adaptation of an existing variety outer functions and activities, the second was the efficient distribution of hard-pavements and green-fields, the third was the treatment of existing slopes and terraces, the fourth was the adaptation of the existing understructures and facilities, the fifth was the creation of nightscape for a night use, the sixth was for harmony of forms and functions like a meet, chat, rest, stroll and assembly, the last was the preparation for erecting a symbolic structure in the future.

The characteristic of Formal Expressions in Deconstructive Architecture were summerized in four features through the results of the analysis. They are as follows. 1) `The relation of architectural element and intertextuality' is expressed in discontinuation of context and refusal of functional building. 2) The concept of trace expresses as connection of place, decomposing of excavation of trace, trace of axis, trace of fragments. 3) Anti-gravity expression is there to express of open cubic, to outgrow of rectangular system, to outgrow of volume, to separate of ground connection. 4) The complex compositon of abstracted geometric form is there to abstracted geometry about indefinite shape, to layer through the overlap and collage, to de-meaning and amusement of form through the pursuit of uncertainty, to indeterminate of formal meaning through operation and composion of similar form cause to the diverse of meaning.

요약문 본 연구는 각종 먼지 가운데서도 독성이 가장 큰 것으로 알려진 도로먼지에 함유된 미량원소 성분이 조성 및 특성을 파악하기 위해 1992년 1월에서 10월가지 주거지역, 상업지역, 공업지역, 교외지역, 전원지역 등에 위치한 도로에서 시료를 채취하였으며 채취된 시료는 산으로 추출한후 ICP로 분석하였다 . 그 결과 토사 및 황사현상과 같은 자연발생원과 연관지을 수 있는 Al, Ca, Mg, Ti, Si, Na, K의 농도가 지역에 따라서는 전원지역과 교외지역에서, 그리고 도로포장 형태에 따라서는 비포장 도로에서 높게 나타난 반면에, 각종 연소 및 차량과 같은 인위적인 발생원과 관련이 있는 As, Cr, Mn, Zn, Pb, Cu, Ni는 공업지역 및 상업지역, 그리고 아스팔트에서 비교적 높게 검출되어 이러한 미량원소성문들의 농도분포는 지역에 따라, 그리고 도로포장 형태에 따라 특징적인 양상을 나타내는 것으로 조사되었다. 또한 As, Pb, Al 등의 일부 미량원소성분들의 농도는 계절에 따른 차이를 나타내었으며, 농축계수에 의한 평가결과 농축계수가 낮게 나타난 Na, Si, Ti, K, Al 등은 자연발생원에 의해 상당한 영향을 받는 반면에 As, Pb, Zn 등은 농축계수가 매우 높게 나타나 이들 성분의 경우에는 인위적인 발생원에 의한 기여도가 큰 것으로 평가되었다. Abstract This study was carried out to characterize the trace elements in street dust known to contain several toxic elements. Street dust was collected in residential, commercial, industrial, suburban and rural area of Taegu and on the vicinity of Taegu from January to October, 1992. Total amount of 16 trace elements in street dust were analyzed by ICP spectrophotometer. While the levels of As, Cr, Mn, Zn, Pb, Cu and Ni were higher in industral and commercial area than any other area by sites and the highest levels appeared on asphalt and cement street by street conditions. Also the concentrations of some trace elements originated mainly from soil (e.g. Al, Ca, Mg, Si, Na) were higher in rural and suburban area by sites and the highest levels appeared in unpaved street by street conditions. The concentrations of several trace elements such as Aa, Pb, Al appeared seasonal differences. The estimated enrichment factors (EF) for Na, Si, Ti, K and Al components showed with soil compositions appeared to have low values, while As, Pb and Zn components showed relatively higher values. These results imply that the latter constituents were likely to be affected by dry and wet depositions of atmospheric particles orginated from anthropogenic sources such as fuel combustion and refuge burning.

Background: There have been many efforts to augment blood flow during cardiopulmonary resuscitation. These efforts have focused on maximizing the effect of cardiac pump or thoracic pump alone. However, considering that the heart is the biggest blood reservoir and increase of intrathoracic pressure can generate blood flow, simultaneous exploitation of both mechanisms may have synergistic effect. We hypothesized that simultaneous chest constriction in addition to sternal compression by standard CPR may have additive hemodynamic effects by preventing deformation of the chest and increase of intrathoracic pressure. Methods and results: we built a new mechanical device to perform compression and thoracic constriction simultaneously. The device consists of two main elements. Piston in the center is to depress the sternum. Strap is to constrict the thorax circumferentially. Strap is attached to both sides of the piston. When the piston is pushed down, it depresses the sternum and pulls on the thoracic strap. To determine strap width to produce optimal hemodynamic effect, we measured hemodynamic parameters with variable widths of strap in two dogs after induction of ventricular fibrillation. Result of the experiment showed that 10cm wide strap was determined to be most effective. We also determined optimal depth of compression to produce maximal hemodynamic effect with animal experiments using two dogs. Animal experiments showed that the highest aortic pressure could be generated when the stemum was depressed to 5 cm. Cardiopulmonary resusciation using a new device could generate higher systolic aortic pressure, coronary perfusion pressure and end-tidal carbon dioxide tension in comparison with standard cardiopulmonary resuscitation in a pilot animal study using two dogs. Conclusion: New cardiopulmonary resuscitation method using a mechanical device designed by us could perform sternal compression and simultaneous thoracic constriction, and generate better hemodynamic effects than standard cardiopulmonary resuscitation in pilot animal experiments.

A 4-year-old male German shepherd dog with reluctance to exercise, swelling of bilateral elbow joint and general depression was referred to the Veterinary Medical Teaching Hospital of Chungnam National University. Swelling, alopecia and lichenification of bilateral elbow joint were observed on physical examination. Osteophytes, sclerosis and joint mouse of bilateral elbow joint were found on radiography. Deformation of medical coronoid process and soft tissue density swelling at caudal part of bilateral elbow joint were also observed on radiography. Computed tomography revealed fragmented medial coronoid process and osteophytes of bilateral elbow joint. Therefore this case was diagnosed as fragmented medical coronois process and degenerative joint disease.

Background and Objectives: We previously reported that, compared with standard cardiopulmonary resuscitation(S-CPR), better hemodynamic effects could be achieved by simultaneous sterno-thoracic cardiopulmonary resuscitation(SST-CPR) in which we compressed the sternum and constricted the thorax circumferentially during the systolic period by using a device. This study was designed to assess whether SST-CPR, compared with S-CPR, improve the survival rate of dogs with cardiac arrest. Subjects and methods: Twenty-five mongrel dogs(19∼31㎏) were enrolled in this study. After four minutes of ventricular fibrillation induced by an AC current, animals were randomized to resuscitate with either S-CPR(n=13) or SST-CPR(n=12). Epinephrine(1 ㎎) was injected into the right atrium every three minutes after the beginning of CPR. Defibrillation was attempted after 6 minutes of CPR. Standard advanced cardiac life support was started if defibrillation was not successful. Results: SST-CPR resulted in significantly(p<0.001) higher systolic arterial pressure(91±47 vs 47±24 ㎜ Hg), diastolic pressure(43±24 vs 17±10 ㎜ Hg), coronary perfusion pressure(35±25 vs 13±9㎜ Hg), and end tidal CO2 tension(9±4 vs 3±2 ㎜ Hg). Two of 13 animals(15 %) resuscitated with S-CPR and six of 12 animals(50%) resuscitated with SST-CPR survived until 12 hours after cardiac arrest(p<0.05). Donclusion: SST-CPR, compared with S-CPR, improves the short-term survival rate in canine cardiac arrest.
