최재시,정원양,김진호,이창환 연세대학교 자연과학연구소 1985 學術論文集 Vol.14 No.-

산화툴륨의 전기전도도를 400~1100℃의 온도영역과 10^-6~10^-1atm의 산소분압범위에서 측정하였다. 일정한 산소분압에서 전기전도도의 대수값을 절대온도의 역수에 대하여 도시한결과 직선관계를 얻었으며 inflection point가 나타났다. 활성화에너지는 고온영역에서 34.5kcal/mole, 저온영역에서 19.3kcal/mole이었다. 전기전도도의 산소분압의존성은 직선관계를 나타내었으며 600~1100℃의 온도영역에서 σ∝Po_2^1/5.3, 400~600℃의 온도영역에서σ∝Po_2^1/6.3이었다. 고온영역에서의 주결함은 V_??이며, 저온영역에서는 O_?? 임이 밝혀졌다. 전도도의 온도 및 산소분압의존성을 해석하였으며, 전도메카니즘을 제시하였다. The electrical conductivity of thulium sesquioxide has been measured from 400 to 1100℃ under oxygen partial pressure (Po_2) of 10^-6 to 10^-1 atm. Plots of log conductivity vs. 1/T at constant Po_2 are found to be linear with inflection point and the activation energies obtained from the slopes are 34.5kcal/mole in the higher temperature region and 19.3kcal/mole in the lower temperature region. The Po_2 dependences of the electrical conductivity are found to be linear and closely approximated by σ∝Po_2^1/5.3 in the temperature range of 600-1100℃ and σ∝Po_2^1/6.3 in the range of 400-600℃. The dominant defect is V_?? in the higher temperature region and O_?? in the lower temperature region. The interpretations of conductivity dependences on temperature and Po_2 are presented and conduction mechanisms are suggested to illustrate the data.

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.

The diastema is defined as a space greater than 0.5millmeter between the proximal surfaces of adjacent teeth. It is a normal stage in the primary dentition and the early mixed dentition(i.e. Ugly duckling stage), especially between the ages of 7 and 12 years. Usually these diastmas close completely after eruption of permanent maxillary cuspid. Genetic factor, heavy labial frenum, habits, degree of deep bite, direction of long axis of incisor and mesiodens can cause midilne diastema. Of these, mesiodens located between both maxillary central incisors can cause diastema. The present case reports show that the abnormal midline diastema caused by mesiodens during Ugly-ducking stage have become spontaneous closure after surgical removal.

This study was performed to measure the skin absorbed doses from full mouth standard intraoral radiography(14 exposures) in bisecting angle and paralleling techniques. Thermoluminescent dosimeters were used in a phantom. Circular tube collimator(60mm in diameter, 20cm in length) and rectangular collimator(35mmX44mm, 40cm in length) were set for bisecting angle and paralleling techniques respectively. All measurement sites were classified into 8 groups according to distance from each point of central rays. The results were as follows: 1. The skin absorbed doses from the paralleling technique were significantly decreased than those from the bisecting technique in both points at central ray and points away from central ray. The percentage rates of decrease were greater at points away from central ray than those at central ray. 2. The skin absorbed doses at the lens of eye, parotid gland, submandibular gland and thyroid region were significantly decreased in paralleling techniuqe, but those of the midline of palate remained similar in both techniques. 3. The highest doses were measured at the site 20mm above the point of central ray for the mandibular premolars in bisecting angle technique and at the point of central ray for the mandibular premolars in paralleling techniques. The lowest doses were measured at the thyroid region in both techniques.

柳時昶,曺鎭久 慶尙大學校 1980 論文集 Vol.19 No.1

In order to investigate the effects of moisture content and compaction energy on the unconfined compressive strength of soil-cement mixtures, a labortory test for soil-cement mixtures was performed at three levels of cement content, five levels of moisture content and six levels of compaction energy. The results are summarized as follows: 1. The unconfined compressive strength of soil-cement mixtures was increased with the compaction energy increased. The increase of unconfined compressive strength was clearly observed until the compaction number became twenty-five, and also the effect of compaction was remarkable when cement content was in high level. 2. The maximum unconfined compressive strength was observed when moisture content of the soil-cement mixtures was higher than the optimum moisture content. 3. The effect of compaction was more conspicuously observed in the case which moisture content was higher than the optimum. 4. The specific gravity of soil-cement mixtures was almost proportionally increased until cement content was increased to 8 percent, but it was kept approximately constant at the cement content of above 8 percent.

The author analyzed retrospectively 94 cases of spontaneous intraventricular hemorrhage(IVH) which were treated with external ventricular drainage(EVD) at the Department of Neurosurgery. Chungnam National University Hospital from January 1990 to June 1994. In all cases, infusion of urokinase was attempted for effective drainage. The peak age group of IVH patients were those in their sixth decade, but in primary IVH, younger patients were more frequently affected. The order of causes of primary IVH are hypertension, arteriovenous malformation. Moyamoya disease and cerebral aneurysm, however, secondary IVH are mostly associated with hypertension and aneurysm. The overall mortality rate was 38%. A low initial Glasgow coma scale(under 5)(p<0.001), a high Graeb score(over 10)(p=0.001), fourth ventricular ventricular hemorrhagic dilation(p=0.001), secondary IVH(p=0.009), unilateral or bilateral pupil fixation at the preoperative stage(p<0.001) and long duration of EVD(p=0.045) are all poor prognostic factors associated with higher mortality.

The purpose of this study is to analysis the change patterns of life style and education of North Korean defectors. The questionnaire of this study is for two hundred North Korean defectors who had entered South Korea in 2001. The questions are about residence, education, legal issue, and health. According to this study, the residences of the defectors were still concentrated on the Metropolitan area. Type of residence has become varied so as to increase proportion of their own-houses and long-term leases. Males had got educated for employment purpose, while females had learned using computer the most. Among age groups, the 20s and the 30s had taken regular education the most. As the length of staying in South Korea had increased, the legal cases had decreased; however, the legal issues had become more complicated. The number of the defectors with chronic diseases has gradually declined; thus, overall health status of the defectors had become better. As the length of staying in South Korea had increased, their needs for supports of basic life had decreased, while the demands for consultation about marriage and legal issues. In the conclusion, we point out several ideas based on this study result, which can be utilized in developing policies and supporting programs for North Korean defector adaptation in South Korea.
