This study aims at revealing the physiological responses of dehydration (DH) and rehydration (RH) in intermittent exercises at the work intensity of 70% HR max. First, with general student public, three times of exercise (each for 20 minutes) at the given work intensity were taken, with a break for 25 minutes respectively. Their heart rate, rectal temperature and plasma electrolyte concentration both DH and RH were measured. Second, in two groups of athletes and non-athletes, 9 rounds of exercise (for 100 minutes) and 8 breaks (for 60 minutes) were taken, with RH forced 10 times to compensate for the subjects' water loss. Their change in sweat loss and plasma electrolyte concentration as well as the IVDP(Intensive Voluntary dehydration Phenomenon) were experimented. The summary of this research follows. 1) Mean heart rate and rectal temperature in intermittent exercises were higher at DH than at RH, growing up at the increasing level of DH. 2) RH saw no change in the plasma concentration of Na+, K+ and Cl-, while DH observed a significant increase. 3) HCO₃made a significant decrease at DH before growing up. 4) Mg++ had no change, while Ca++ increased significantly at RH and DH. 5) Lactate showed an increase with significance at RH and DH, especially greater at DH. 6) Osmotic pressure increased meaningfully at DH. 7) Anion gap increased significantly at DH and RH. 8) On the other hand, when the forced RH was held, the group of athletes had greater sweat loss per body surface area than that of non-athletes. 9) The athletes' plasma concentration of Na+ and Cl- revealed a clear decrease. 10) There was seen no significant change in the plasma concentration of K+, Mg++ and Ca++ in both groups. 11) The IVDP occurred at the RH of 2.3ℓfor athletes and more than 2.5ℓfor no-athletes.

연구목적 : 건간한 의대상 312명과 신경증적 장애를 가진 환자 288명을 대상으로 하였다. 사상체질의 구별은 노정우 및 김달래 두 전문가에 의한 판정, 그리고 경희의대 사상체질 설문지(QSCC Ⅱ)에 의한 판정 등 3가지 방법에 의하였다. 연구 대상에게 정신과적 증상척도(SCL-90), 체질특성척도 및 성격척도를 사용하여 자가 평가하게 하였다. 각종 척도들의 타당도와 신뢰도는 입증되었다. 이 척도들을 통계적으로 분석하고 고전적 설명과 어느 정도 일치하는 지를 검토하였다. 연구결과 : 1) 3가지 분류방법간에 차이가 컸었다. 그 중 전문가의 직접적 면담에 의한 감별보다 QSCCⅡ 설문지형이 비교적 감별력이 컸다. 3) QSCCⅡ가 감별력이 비교적 크다고 하더라도 그 결과가 소음군의 대인공포-강박증, 불면-식용상실, 무력-예민-소화기-한기-피부증후군 그리고 정력부족등 신경증적 증상과 소극-비사교적, 내향형 성격 및 이성적 성격특징 등 몇가지 특징을 감별하는 데에만 비교적 유의하였고, 태음군의 특정인 독특한 신념, 온기, 활달-사교적 성격에 대해서는 부분적으로 그 특징을 감별하였다. 또한 소양군의 활달-사교형 성격과 감정형 성격의 특징 등은 극히 부분적으로 감별하였다. 결 론 : 이러한 결과는 현존하는 사상체질 구분방법에 일치점이 결여되어 있다는 것, 각종척도를 사용한 결과는 사상체질에 관한 고전적 설명을 부분적으로만 입증하고 있다는 것, 따라서 사상체질구분에 대한 향후보다 객관적인 연구가 필요하다는 것을 시사한다. Object : This study is to examine the validity of constitutional classification of Sa-sang medical theory. This theory classifies the human constitution to 4 types according to classical oriental philosophy on yin and yang. Subjects and Method : Subjects were 312 medical students and 288 neurotic patients with diagnosis of neurotic, stress related and somatoform disorders and minor depressive episodes according to ICD-10. Medical students were classified to 4 Sa-sang Constitution Classification(QSCCⅡ). For assessmnent of symptoms and signs, Korean version of SCL-90, a constitution scale and personality scale which were designed for this study were used. These instruments were found to be reliable and valid through statistical analysis. Subjects were asked to rate these scales. The data were analysed with factor analysis and factor scores were compared among 4 Sa-sang constitutions by ANOVA and t-test. The data from patient group were analysed with factor analysis and the results were compared with the Sa-sang medical theory. Results : Results of classification by 3 ways were inconsistent showing a significant difference among them. Among them, QSCCⅡ was most reliable. In QSCC Ⅱ, only the factor scores of factors of homophobia-obsession, weakness-sensitiveness-indigestion-chillness-skin syndrome, sexual weakness, passive-unsociable personality, introverted personality and rational, personality, were significantly high in So-um (small yin) group of medical students. A factor of warmnes and active-sociable personality were significantly high in Tae-um(big yin)group. Also active-sociable and effective pesonality was partly related with So-yang(small yang)group. Conclusion : These results suggest that those present classification methods inconsistent, that these methods are proving only parts of Sa-sang medical theory, and that objective and scientific studies are needed for reliability and validity of Sa-sang medical theory.

Background : This study was performed to determine the cut-off value and the predictability of symptomatic human cytomegalovirus (HCMV) infection according to the peak value of HCMV antigenemia assay in kidney transplant recipients. Materials and Methods : We reviewed the results of HCMV antigenemia assay (Chemicon, CA, USA) in patients who received kidney transplantation at our institution from May 2003 through May 2008, and investigated the existence and the type of HCMV infection by the medical record review. Patients who underwent the test only once during the episode or those who received ganciclovir for more than 48hrs before the test were excluded. The receiver-operator characteristic curve was drawn and the point showing maximum likelihood ratio (LR) was chosen as the cut-off value of symptomatic HCMV infection. Results : A total of 689 episodes were screened and 134 episodes were enrolled. Thirty-three (24.6%) episodes were symptomatic HCMV infection, 23 (17.2%) episodes were associated with HCMV syndrome, and 10 (7.5%) episodes were tissue-invasive diseases. The maximum LR was 7.5 (95% confidence interval, 4.014.2) and the cut-off value was 29.5 cells/200,000 WBC. The sensitivity, specificity, Positive predictive value, and negative predictive value were 66.7%, 91.1%, 71.0%, and 89.3%, respectively. Conclusions : The cut-off value of symptomatic HCMV infection by the peak value of HCMV antigenemia assay in our study was similar with previous results, although the sensitivity was relatively low.

This study was conducted to suggest appropriate methods for management of urban forest after investigating the present condition and problems of urban forests by analyzing vegetation and soil properties in urban forests in the Daejeon. On the basis of our research, Pinus rigida dominate Gyejoksan and Bomunsan. Pinus densiflora dominate Wolpyeong park and Quercus acutissima dominate Namsun park. On the basis of our result of analysis of soil chemical properties, all investigated areas have low pHs, available phosphates and exchangeable cations. They indicate that the soil of those areas have been acidifying progressively. Soil hardness measurements were conducted to know the conditions of trampled soils and the results of them show that soil hardness in Namsun park was higher than the others. This indicates that human interference affect the health of the urban forest.

In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria gonorrhoeae(PPNG), we have been trying to study the patients who have visited the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by menas of the chromogenic cephalosporin method. In 1998, 93 strians of N. genorrhoeae were isolated, among which 60(64.5%) were PPNG. The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 64.5% in 1998.

Epoxy resin based upon the N,N'-diglycidylaniline was modified with poly(amic acid)(PAA). Prior to aromatic amine cure, the possible reactions in the epoxy resin/PAA blends were investigated used FT-IR and inherent viscosity techniques with the addition of 4,4'-diamino-3,3'-diethyldicyclohexylmethane(3DCM) as hardener. PI-modified epoxy(GAYA) blends were prepared by IPNs method. IR, TGA, DSC, DMA, TMA and UTM are used to measured the thermal and mechanical properties. Thermal stability increasing with increasing PAA content in blends. Lowering Tgs with increasing PAA content in blends are observed except for the blend modified with thermoplastic. Improvement of the impact strengths in J/M in the range 920∼2,412 are observed for blends and the improvement of the impact strength is closely related to the content of PAA in blends. A rough surface was observed by SEM examination on the propagation surface of the impact specimen, while a smooth surface is observed on the unmodified epoxy specimen. The morphological observations suggest the PAA segment may act as a toughening agent in the epoxy networks, thus contributing to the impact improvement of the blends.

多國籍企業의 國家的 目標 實現上에 나타난 제 Factors에 關한 硏究

The Multinational enterprise as an economic institution seems capable of adding to the world's aggregate productivity and economic growth, as compared with the visible alternatives. In some kinds of industries, its contribution to productivity and growth seems less than in others. There may even be industries in which the existence of multinational enterprise is stifling to growth, though these situations are probably exceptional. Conclusions regarding the distribution of the benefits of that growth are more uncertain. However, the idea that the "lending" country captures all the benefits while the yield to the "borrowing" country is zero or negative seems altogether improbable. As for the distribution of benefits within the countries, it is difficult to say how the operations of multinational enterprises are affecting the outcome. For instance, the question as to whether existing inequalities of income are enlarged or reduced in host countries by the operations of multinational enterprises depends partly on the alternative economic systems one has in mind. There is no evidence that economies which retain elements of a decentralized enterprise system, such as the Japanese, the Mexican, and the Yugoslav economies, have managed to develop more egalitarian income distributions by placing special limitations on the scope of multinational enterprises. Although it is hard to say just what effect multinational enterprises have had on national income distribution, some other effects of the multinational enterprises have been clear. As a rule, the presence of multinational enterprises has generated tensions in the foreign countries where they appear : not much in some countries, but a great deal in others. When such enterprises are headed by U.S. parents that fact generally tends to increase the lebel of tension associated with their presence. As a rule, the tension is a manifestation of powerful psychic and social needs on the part of elite groups in host countries. These needs include the desire for control and status and the desire to avoid a sense of dependence on outsiders. Different value systems lead to different definitions of the problem of the multinational enterprise. The problem contains several elements. Sovereign states have legitimate goals toward which they try to direct the resources under their command. Any unit of a multinational enterprise, when operating in the territory of a sovereign state, is also responsive to a flow of commands from outside, including the commands of the parent and the commands of other sovereigns. Moreover, the multinational enterprise as a unit, though capable of wielding substantial economic power, is not accountable to any public authority that matches it in geographical reach and that represents the aggregte interests of all the countries the enterprise affects. As long as these two issues remain unsolved, the constructive economic role of the enterprise will be accompanied by destructive political tensions.

The study on foreign direct investment of Korean corporations is of great importance. Many a study till now, however, ⅰ) is largely concentrated on the management activities of foreign-owned multinational corporations in our country and their influence on our national economy, and ⅱ) is concerned with the macroscopic analysis of foreign direct investment of Korean corporations, not with the establishment of strategy appropriate to the environment of host country and the investment performance. In order to meet the problems mentioned above the present thesis aims at accomplishing the following four tasks. 1) synthetic assessment of existing theories of foreign direct investment. 2) systematic adjustment of factors of environment, strategy and performance in the foreign investment activities. 3) empirical analysis of above factors in the foreign direct investment of Korean enterprise and proper proposal of strategic model for the individual corporation. 4) possible overcoming of limits in existing studies on the basis of empiricism. The results of emprical analysis according to the aim of the study are as follows: 1) The size of corporation and the life cycle of product besides the legal and political environment of host country affect the marketing strategy of investment corporation, such as product, distribution channel, price, and sales promotion. 2) The environment factor of host country is found, as is observed in the existing studies, to influence raw materials and parts supply source, investment mode, and sales market construction. 3) The component ratio of native employee changes according to the difference in cultural and social environment between home country and host country. 4) The method of disinvestment depends upon the investment mode, and the method of foreign exchange risk management depends upon the investment size and the fund raising source.
