Chick embryo is a convenient model for embryologic teratologic studies. We performed the present experimental study to establish the basic technology for magnetic resonance studies of chick embryos and to examine the biochemical changes occurring during the development of chick embryos. Fertilized Leghorn eggs were examined by 31-phosphours magnetic resonance spectroscopy (??P-MRS) on days 6, 9, 12, 14, 15, 17 and 20 after the start of incubation. Spectroscopic data of live embryos were acquired by using a 4.7T MR spectrometer, and signals from phosphorous metabolites were analyzed. Total phospholipid signal decreased, which resulted in the overall decrease in total phosphorous signal over time. Signals from other metabolites such as ATPs and phosphocreatine increased over time, while those from inorganic phosphate and sugar phosphates decreased. Before the incubation days 12, signals from sugar phosphates and inorganic phosphate were predominant, and other metabolites became remarkably functional between the days 12 and 14 when the decrease in the phospholipid signal was significant. MR specrtroscopy is an effective method in evaluation of the biochemical changes occurring during the developmental period of chick embryos.

Our country has many limestone caves. There are about two hundred and thirty caves all over the country. Among them ninth percentages are limestone caves. We divide them into four classes as the limestone cove, lava cave erosion cave. We dlassify them with the component of formation for example, the limestone cave in the Karst region, the erosion cave in the seaside and the lava cave around the volcanic zone in Jeaioo Island. With geographical distribution, we could discover the limestone eave generally around the Gangwon Province, the Gyungsang Province the Chungcheung Province and the lava cave in Jea boo Province. The erosion caves are developed along the coast. With the geological period, we could discover the limestone cave mainly in the Cambro-Oldovisian Stage. We can see the anvient creature in the cave, not discovered at the surface, because the living things in the cave were late for the development. And the direction of the cave has connection with geological features. Mainly it agree with a fault plane. Generally Caves maintain the temperature from 14 degrees to 17 degrees. Thus, the fried temperature is a character of the cave. From old time, cave is made use for the place of the residence. Academic study for the cave began in earnest at the late 19th century. Comparaticely spealcing, we started studying only ten years ago. We used only cave for the place of refuse. And the cave is used for storehouse or the place in order to train the mind. Now we had to study to utilize the cave in our new period. For the temperature of the cave is fixed, we can use the cave for store. Now we had to study to utilize the cave in our new period. For the temperature of the cave is fixed, we can use the cave for storehouse of the crops or of the military goods. It is important for the cave to use for the military strategy. And it is possible to captivate the mushroom in the cave. Besides, we can use the pond of the cave for fish-breeding, as Japan is utilizing the cave for a fry-breeding. It is vary important to investigate the size or form of our many caves so as to serve the national safety.

This paper reviews the general status of stalactite caves which were found and are utilized for sight-seeing in Korea, and also summarizes the results of investigations on properties of natural stalactite caves. The cavernous phenomena such as the water quality, atmospheric phenomena, secondary grown products, ecological adaptation, environmental pollution and the breakage of stalactite are compared between those of cave a which are opened already sight-seeing and unresults are discussed and also compared with the caves in other countries. Environmental pollutions in Korean stalactite caves are as the following : The animate matters in caves are disappeared gradually from the time of exposure for sight-seeing. The kinds and abundance of the animate matters favoring the cavernous life or coming from the outside of caves have relativity to temperature, moisture and atmospheric conditions in caves. The water quality is consistent throughout the entire flow passage in a cave, but calcium content were less with the increase of flowing water volume in a cave. Atmospheric phenomena at entrance of a cave show a slight difference from the inner atmosphere, and the moisture content in cavernous atmosphere are increased with the cave depth. The secondary growth of stalactite are not taken place at the entry, because of low moesture content in air. However, stalactite secondary growth were prominent at inner cave where the moisture content is more than 90%. The temperature variation in the caves are negligible through all seasones in a year. The following conditions are critical to conserve the cavernous environmental pollution and the original form of caves. Some caves should not be exposed to the sight-seeing for academic studies. If the caves are open for sight-seeing, the entrance should be restricted with an adequate to limit the changes of atmospheric phenomena. In rainy season, the surface water flowing outside of cave should be protected from entering into the caves and water pool should be drained out to outside of cave. Proper number of waste cans should be provided along the pathway in the caves.

Many Natural Caves are spreaded over the our country. In old times, the forefathers made use of them for the house, the shelter, a place of the discipline, and the military base. At large these caves are divided into the three classes. They are limestone cave, Lava tunnel and sea erosional cave. Limestone cave are spreaded over the area of Sam-Chuck, Young-Wol, Pyong-Chang, Jeong-Seon in Kang Won Do, and Dan-Yang in Chung-Cheong Buk-Do and Ull-Jin in Kyong-sang Buk-Do, Lava tunnel is distributed to Che-Ju Island. We can discover sea erosional cave in the souther coast region. The caves witch are famous for limestone cave are Song-Ryu cave in Ull-Jin. Go-Si cave and Yong-Dam cave in Young-Wol, Hwa-Am cave in Jeong-seon, Go-Su cave and On-Dal cave in Dan Yang, Cheon-Ho cave in It-San, Yeong-Jae cave in Hwa-sun and Gim-Nyeon cave, Man-fang cave, Bilemok cave, Hyeb-Jae cave in Che-Ju Island. Most of them are develop for the tourist exploitation. Go-Si cave is famous for the rare creature. Then all of our limestone eave are distributed to the region of limestone cave. Most of them belong to Ordovician period. Their development was established in ancient time. Among Speleothem of the cave in our country particulary, stractite and stalagmite advanced on a large scale, and a lot of colum are immence. The other hand, the entrance of Lava tunnel in Che-Ju Island have anything peculiar which was built when the ceiling was sink. Then our caves have a great value of academic by the reason of the geographical spectacle. The character of creature in the cave will be a great help to the academic study. In addition, the cave which has a profitable condition in the tourist exploitation issuspected to develop in future.

소득분배를 결정하는 권력 추구의 안정 그리고 불안정한 균형점에 대하여

홍성필,이시영 중앙대학교 산업경영연구소 1997 산업경영연구 Vol.6 No.1

This paper presents a simple model of power struggle. We assume that two individuals (or groups) are identical except their marginal costs of power build-up. We provide the conditions that produce stable and instable equilibrium. The main factor that determines the existence of an instable equilibrium is the difference in marginal cost of power build-up between two individuals. Since the nature of an instable equilibrium insinuates the unpredictability of outcomes, two parties may take actions to avoid such an outcome: (1) Two parties never get together in the first place (segregation) and consume their own endowments separately. (2) A party with low marginal cost may induce to lower the other's marginal cost (in form of subsidy) to support a stable outcome.

남한 내 북한이탈주민의 3년간 사회적응 추적 연구 : 2001년부터 2004년까지 생활과 교육을 중심으로 With prioty given to life of North Korea defectors from 2001 to 2004

Purpose of this study : In 2001, this study that investigate actual conditions about adaptation degree of Korean social life of the North Korean defectors was carried out to 151 people that succeed in chases among 200 the North Korea defectors answer in study. Purpose of this study is as following. First, we wished to search change aspect of actual conditions about South Korea society adaptation of the North Korean defectors who take part in the first investigation for past 3 years. Second, we wished to search difference of adaptation aspect by populational and social element. Third, We wished to suggest things that can be beaconed to efficient support policy of government or private organization and successful South Korea social adaptation method which support the North Korean defectors on the basis of study finding about change of adaptation aspect of the North Korea defectors. Methods of Study : We designated 200 Panels to study and survey actual adaptation conditions of the North Korean defectors on South Korea society synthetically and for long-term. So, chasing about 151 people was possible in 2004. We are fertilized and supplement the questionnaire forming in 2001 and composed the new questionnaires to part of a life, mental state, Body and health. This study among them investigated a standard of living of the North Korean defectors. In this process, interviewer directly asked and recorded questions to reduce individual variation of people who receive interview. Study Results : Government's residence support policy about North Korean secession inhabitants was generally attained as effective and suitable for North Korean inhabitants' early South Korea settlement. Only, government need to discuss about North Korea secession inhabitants' residence support more variously for long-term. Second, education should be supported more actively and variously. Suitable point of education for their needs should make a effect of vocational training or education maximize. This is a very important part. Third, they need guidance and education that can receive more easily law support. Fourth, medical supports and health cares should be achieved continuously and systematically to them since they arrived in South Korea. To supports and studies North Korean secession inhabitants has the large significance to gain a foothold about reunification of North and south. Their South Korea society adaptation is becoming topic of conversation among South Korean. An atmosphere of unity is elated. And interest degrees about North Korean are actually rising as exchanges between South and North Korean is activated. Therefore, the adaptation study about North Korean secession inhabitants will have to be expanded in studies for South Korean, not to be limited in studies for North Korean.

Background: Pain is major problem regarding quality of life in children undergoing tonsillectomy. Preemptive analgesia by medicine given before commencement of surgery is a new recommended for relief of pain during and after operation. We compared intra-and postoperative analgesic and recovery characteristics of tramadol, meperidine given at induction of anesthesia in 40 ASA I or II children undergoing tonsillectomy with or without adenoidectomy. Materias and Methods: Fourty children aged 4-7 years undergoing tonsillectomy with or without adenoidectomy were randomly assigned to receive either tramadol 2 mg/kg (group 1) or meperidine 1 mg/kg (group 2) at induction of anesthesia. Thiopental sodium (5 mg/kg) and rocuronium (0.6 mg/kg) were used for the induction of anesthesia, and it was maintained with sevoflurane in N₂O/O₂50/50 via an endotracheal tube. Pain assessment was done by facial pain scale. Agitation scores, time to recovery of spontaneous respiration and the incidence of postoperative nausea and vomiting. Heart rate and mean arterial pressure was recorded at regular intervals. Results: Facial pain scale scores were increased in group 1 at 10 and 20 min in recovery room. There was no difference for agitation scores in the two groups. Intraoperative mean arterial pressure (15th min) were found to be higher in group 1. The time to recovery of spontaneous respiration was delayed with group 2 compared with group 1. The incidence of nausea and vomiting was not statistically differed between groups. Conclusions: Meperidine was more effective for pain relief than tramadol after tonsillectomy in children.
