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.

Purpose: The purpose of this study was to assess the effect of a prophylactic cable fixation for prevention of femoral fractures in cementless bipolar hemiarthoplasties. Materials and Methods: Forty-eight cementless bipolar hemiarthroplasties with prophylactic cable fixations on the femur were performed in patients>65 years of age between January 2004 and August 2008 (group 1). The control group which did not undergo prophylactic cable fixation included 48 cases (group 2). The mean age was 75.4 years (group 1) and 73.6 years (group 2). The patients were followed up for an average of 19.1 (group 1) and 18.3 months (group 2). The intra-operative fracture rates were compared. Additionally, operative time, estimated blood loss (EBL), and length of hospital stay were compared. Radiologic assessment for stem stability was performed. Clinical assessment was evaluated by the thigh pain and Jensen`s functional score, and Parker & Palmer`s mobility score. Results: There was no fractures in the cabled group (1), and 4 fractures (8.3%) in the control group (2; p=0.041). The mean operative time was 172 minutes (1) and 162 minutes (2), the EBL was 866 cc (1) and 855 cc (2), and the duration of admission was 36 (1) and 35 days (2), respectively. Radiologically, subsidence was 1.59 mm (1) and 1.67 mm (2). Clinically, one (1) and two (2) thigh pains were recorded and the functional score of Jensen was 2 (1) and 2.2 points (2), and the mobility score of Parker and Palmer was 5.2 (1) and 5.3 points (2), respectively. Conclusion: Prophylactic cable fixation is effective for reducing intra-operative femoral fractures.

Michel Dedre said, "If democracy doesn't establish a system to prevent real estate speculation, and doesn't have any means to charge taxes on some amount of automatical increasing land price caused by establishing governmental public facilities, it will run the great risk of being incompetent in finance as well as policy." According to the above statements, to control our present real estate system, especially the building land, is very important for public welfare. In this paper, to promote the utility of building land by public law control on landownership, and to take a part in carrying out public welfare throughout the equal opportunity of making use of land, I referred to some problems concerned. The gists of this paper are followings: 1st chapter; the characteristics of landownership and the cause of real estate speculation. 2nd chapter; the public welfare suitability of exercising property and constitutional protection of property on "O¨ffentliches Landbegriff." 3rd chapter; the various nation's cases about controling of landownership, such as Korea, German, England, America, Free China and Japan. As a result, I'd like to suggest some basic courses of land policy as followings: 1. The need for establishing basic law of land. 2. The need for a long-period and effective counter-plan of land. 3. Developing all kind of land according to the usage designated by government. 4. Introducing the licence system of land business. 5. Introducing a system of limiting land tenure. 6. Limiting long-period land tenure. 7. Collecting development texes in case of changing land usage. 8. Improving the real estate businessmen's qualities, and introducing the business licence system.

The purpose of this study is compared with VO₂max, aerobic and anaerobic threshold of elite rowing and canoe player. For the subjects, 15 members of athlets were chosen, 8 members of rowing and canoe elite player. They did exercise with start speed of 140m/min without treadmill slope and the speed was incremented by 20m/min every minute and they were finally led to exhaustion. Ventilation was continously measured by douglas bag method every minute. The measurement of aerobic and anaerobic threshold were done by non invasive indices. Aerobic threshold (Aer T) was decided by the changing point of the first increment of the ventilation and the change point of V??ㆍVO₂?? and F??O₂. Anaerobic threshold (An T) was decided by the changing point of second increment of ventilation and changing point of V??ㆍVCO₂?? and F??CO₂. The conclusion were as follows: 1. There was no significant difference in VO₂(ml/kg.min) of the rowing players for the canoe players. But VO₂max(ℓ/min) was significantly difference. 2. For VO₂Aer T, VO₂An T, %VO₂AerT and %VO₂AnT of rowing players was significantly higher than canoe players and there was no difference in any other factors.

Rudolf Stammler의 法理念論

朴龍喆 慶北大學校 師範大學 1981 敎育硏究誌 Vol.23 No.-

Stammler has established the system of critical philosophy of law, applying Kant's criticism more strictly than Kant himself to the basic problems of the law. Stammler has contributed a great deal to the development of philosophy of law in twentieth century by attempting to study the relative and practical objects rather than absolute and permanent ones which are usually dealt with in natural law and historical law. He has recognized the particular methodological significance in the philosophy of law and understood the law systematically and uninformly. The significance of his contribution lies in the fact that he applied the achievements of new Kant's philosophy to the philosophy of law. Though Stammler's system of critical philosophy of law appears grand because of strict methodology and thorough logic, it has not helped very much to solve the basic problems in philosophy of law in the contents. For the universal principle of law cannot be established only by forms of law which lack the contents of law, moreover the universality of law forms which lack the contents cannot help to solve the living social problems. But the idea of "natural law which has changing thoughts" which is derived from Stammler's theory of law is of great significance because it rejects the hardened natural law of the Enlightment, and because it gives flexibility and elasticity to the natural law. The law is not always good that is a firm order. People hope that law will adjust itself to the change of history and that it will be a changeable, flexible order suitable for an individual case or state. Accordingly, the law should not static state safe, but keep incessantly advancing state safe. In this respect, Stammler's idea of dynamic natural law gave philosophical basis to the theory of the free law which asserts that the law should be enforced flexibly according to the changes of social life.

言論의 自由와 Privacy의 權利

It is said that the nature of human-being has the figure of Janus. Therefore a human being has a contradictory propensity in his social behaviors; that is, to pursue the unknown world out of curiosity and to take a pleasure for his secrets. In this reason, the freedom of speech and press has been a feud with the right to privacy, and this is why that we are going to investigate the various legal problems of privacy in this paper. Generally, we hope for harmornization the freedom of speech with the right to privacy. Since we like in a so-called information-oriented society, the more the technology of information develops, the more privacy diminishes. Also the rapid progress and monopoly of the mass-media bring about the result of infringing a basic human right, especially the one like the right to privacy, with in curcumstances of Yellow Journalism and Commercial Business. Keeping in mind on the present conditions of freedom of speech and press, In this thesis, I made a survey on five points; (1) The modern circumstances of mass-media and the freedom of speech and press. (2) The concept and legal characters of the right to privacy. (3) Types of privacy torts; 1. Intrusion 2. public disclosure 3 publicity 4 appropriation. (4) Legal protection and vemedies for privacy torts. In conclusion, I thought the concept of the right to privacy in modern welfare state shall be difined in a positive way, precisely the private date subjects to the right to control information about himself. And I suggested the enactment of a privacy act which contains remedies for privacy torts and validities of the right to privacy among individuals.

Although the term "generally accepted ideas" is widely used, it has been used with various meanings in the application of the law, each time with its particular role. This study is to investigate the problems between the law and generally accepted ideas, between generally accepted ideas and empirical laws in the application of the law, the usage of generally accepted ideas, and the relationship between facts and empirical laws and the laws related to generally accepted ideas, and so forth.

휘발성유기화합물(VOCs)의 변이원성 검정

박종천,이용탁,송현철,이우범 國立麗水大學校 環境問題硏究所 2004 環境硏究論文集 Vol.6 No.-

The mutagenicity of six kinds of VOCs(benzene, m.p-xylene, chloroform, toluene, methylethylketone, 1,2-dichloroethane) detected in high concentration and frequency in Kwangyang Bay was investigated. VOCs are water-insoluble and volatile. Therefore, when they are tested by the classical Ames test in the assay of mutagenicity, there may be experimental errors. To overcome this limitation, modified Ames test was used to assay mutagenicity of VOCs. By this modified Ames test, we could obtain much more satisfactory results. Even at extremely low concentration(0.0001㎍/㎖). bezene, m,p-xylene, and methylethylketone showed a weak mutagenicity. When S-9 mixture is added in the assay system, all tested VOCs except methylethylketone showed mutagenicity. When Salmonclla typhimurium TA 98 and Salmonella typhimurium TA 100 are exposed to VOCs of high concentration(100㎍/㎖). the number of colony decreased irrespective of the S-9 mixture treatment. It seem to be that the decrement results from the toxic effect of high concentration of VOCs.

Looking into the existing study result on the effect of charistmatic leadership is that it realized to be an important relation between the charistmatic leadership and related to result and attitude. Looking into the studies on the changing effect of charistmatic leadership is that the effect of charistmatic leadership found to show up the devotion, self-sacrifice for the mission of group, high satisfaction and result, the trouble reduction of role, the increase of the cohesive power of group, and so on(House et al, 1993 ; Howell & Frost, 1988 ; Shamir et al, 1993). Also, according to the studying result of Harter and Bass(1988), the leadership perceived by charismatic leadership finds to be the satisfaction and a definition relation on the leader efficiency and a leader. As above the effect of charistmatic leadership showed most of an important relation. Also, through the medium of self-concept based on the motive grant mechanism of charismatic leadersp, these effects have predicted to find through this theory study. According to this study, the head coach and coordinator of sports group and the phenomenon of charismatic leadership between players are able to predict to occur based on relational basis to accept generally as the cause of an appearance of charistmatic leadership in present, and will get attained the development of measurement tools and an actual proof study.

회전 불변특성을 가지는 패턴 팽창법

박영석,최철용 慶南大學校 附設 工業技術硏究所 1998 硏究論文集 Vol.15 No.2

패턴의 팽창 경계선(dilated boundary)을 생성하는 4 방향 팽창(4-neighbor dilation) 혹은 8 방향 팽창(8-neighbor dilation)과 같은 2진 팽창법(binary dilation)에서는 회전 각도에 따라 추출된 패턴의 윤곽 형상이 매우 달라진다. 본 논문에서는 패턴의 회전에 대하여 불변특성을 지니는 교번 팽창법(alternate dilation)과 원형 마스크 팽창법(circular mask dilation)을 제안한다. 교범 팽창은 패턴의 회전 불변특성을 크게 개선한다. 그리고 원형 마스크 팽창법은 교번 팽창법 보다 더욱 강인한 회전 불변특성 제공하며 처리시간의 관점에서도 가장 우수한 특성을 지닌다. In the existing binary dilation method which generates a dilated boundary curve of pattern, such as 4-neighbor dilation or 8-neighbor dilation, The extracted curve shape is very different depending on the rotation angle of pattern. In this paper, we propose two binary dilation methods called alternate dilation and circular mask dilation, respectively. The first can greatly reduce the rotation-dependent variation of pattern. And the second provides more robust rotation-invariant characteristics than alternate dilation approach and takes the most excellent processing time.
