Many studies have reported the frequency and distribution of haplogroups among various cattle breeds for verification of their origins and genetic diversity. In this study, 318 complete sequences of the mtDNA control region from four Korean cattle breeds were used for haplogroup classification. 71 polymorphic sites and 66 haplotypes were found in these sequences. Consistent with the genetic patterns in previous reports, four haplogroups (T1, T2, T3, and T4) were identified in Korean cattle breeds. In addition, T1a, T3a, and T3b sub-haplogroups were classified. In the phylogenetic tree, each haplogroup formed an independent cluster. The frequencies of T3, T4, T1 (containing T1a), and T2 were 66%, 16%, 10%, and 8%, respectively. Especially, the T1 haplogroup contained only one haplotype and a sample. All four haplogroups were found in Chikso, Jeju black and Hanwoo. However, only the T3 and T4 haplogroups appeared in Heugu, and most Chikso populations showed a partial of four haplogroups. These results will be useful for stable conservation and efficient management of Korean cattle breeds.

N/A Minima1 deterioration of cerebral perfusion or microanatomical changes were undetectable on conventional Brain CT or MRI. So evaluation of focal functional changes of the brain parenchyme is essential in chronic head injury patients, who did not show focal anatomical changes on these radiological studies. However, the patients who had longstanding neurologic sequelae following head injury, there had been no available imaging modalities for evaluating these patients precisely. Therefore we tried to detect the focal functional changes on the brain parenchyme using Tc-99m-HMPAO Brain SPECT on the patients of chronic head injuries. Twenty three patients who had suffered from headache, memory dysfunction, personality change and insomnia lasting more than six months following head injury were included in our cases, which showed no anatomical abnormalities on Brain CT or MRI. At first they underwent psychological test whether the symptoms were organic or not. Also we were able to evaluate the cerebral perfusion changes with Tc-99m-HMPAO Brain SPECT in 22 patients among the 23, which five patients were focal and 17 patients were nonfocally diffuse perfusion changes. Thus we can predict the perfusion changes such as local vascular deterioration or functional defects using Tc-99m-HMPAO Brain SPECT in the patients who had suffered from post-traumatic sequelae, which changes were undetectable on Brain CT or MRI.

Purpose: To determine postoperative astigmatic changes after surgery for congenital ptosis and the astigmatic changes depending on surgical method and to discern cases of postoperatively developed anisometropia or amblyopia. Methods: Fifty-one patients who underwent surgery due to congenital ptosis were reviewed. Refraction or cycloplegic refraction was conducted preoperatively and 3 to 6 months after surgery to measure astigmatic changes. Astigmatic changes in operated eyes were compared to control eyes. Astigmatic changes were compared depending on surgical method. Results: The mean astigmatism was 1.33±1.29D preoperatively and 1.48±1.13D postoperatively (P=0.10) and the mean astigmatic change in the ptotic and control eye was an increase in cylinder +0.56±0.55D and +0.68±0.72D (P=0.37). The mean astigmatic change of patients receiving frontalis sling was +0.57±0.67D which was similar to those who received levator resection (+0.56±0.50D). Newly developed anisometropia was found in three patients postoperatively due to an increase in astigmatism, but newly developed amblyopia was not found. Conclusions: The increase of astigmatism by ptosis surgery was not statistically significant and there was no statistically significant difference when accounting for surgical method. However, it is necessary to monitor refractive error carefully in younger patients to prevent amblyopia because postoperative increase of astigmatism can cause anisometropia.

The purpose of this work is to investigate the static strength, the stress distribution, and the failure process of quasi-isotropic composite laminates made of two different matrices when loading directions are changed. We carried out static tests of [0/-60/+60]<SUB>s</SUB> and [+30/-30/90]<SUB>s</SUB> laminates. Two types of matrices used are AS4/epoxy and AS4/PEEK. The damage mechanisms of the quasi-isotropic laminate, [0/-60/+60]<SUB>s</SUB> strongly depend on the load direction applied to the laminate.

This study is a comprehensive survey of the introduction, adoption, and diffusion of modem sports that had their origins in the West. Supporting data were collected and arranged according to the following categories, and based on this, the introduction, adoption, and diffusion of western sport in Korea was subjected to a structural analysis. 1) Introduction : This includes the first instances of the appearance(both individual and group) of each sport, the first known instances of competitions, relative time of introduction of each sport, and changes over time, and changes in different sport areas. 2) Adoption: This is based on a re-organization of the 552 recorded completions between 1910 and 1940 as found in the book 70 Years of History of the Korea Sports council published by the Korea Sports Council in 1990. The main findings of this study are as follows: 1) Introduction: Analysis of introduction of western sports by time period showed that before 1900, that is before the Japanese annexation of Korea, football(soccer), cycling, tennis, gymnastics, track and field, equestrian, swimming, shooting, and baseball were introduced.. Within the sphere of activities of such organizations as the Hwangseong Christian Youth Association boxing, volleyball, rowing, table tennis, rugby, and weight lifting were introduced after 1910. Introduction was brought about through foreign missions, Korean diplomats, and educational programs. 2) Adoption (1) During the initial period during which sport was putting down roots in Korea(1910-1919) at least one or two sporting events were held per year consisting of track and field, baseball, and tennis. (2) During the growth period(1920-1927), as competitions became yearly events, the number of competitions increased steadily from 4 in 1920 to 20 in 1927. Events were held in baseball, track and field, tennis, and football(soccer) and teams and clubs were formed. Beginning with the Chosun Sports Council governing bodies were established for the various sports. (3) During the settlement period(l928-1937), particularly during 1928 and 1929, the number of sports being competed greatly increased by 10-14 events and the number of events also increased to between 30 and 40 showing that the sport situation was starting to stabilize. The type of hosting bodies for sports events also diversified and increased.. (4) After 1938 there was a decline in the number of events being hosted and in the number of sports being competed. This was a result of the effects of the Pacific war on all aspects of social development.

The objectives of this study, an analysis of the variation for leaf and fruit characteristics among the selected ten populations of Sorbus commixta Hedl. could be used for the conservation of gene resources and could provide information to superior trees selection. The results obtained from this study can be summarized as follows; Approximately, the Mt. Sungin population at Ulleung island showed larger values in overall characteristics and populations. On the other hand, Mt. Halla population at Jeju island showed the smaller values of the overall characteristics and populations. ANOV A tests showed that there were statistically significant differences in all leaf characteristics among the populations as well as individual trees within populations. But, for fruit characteristics, differences were statistically significant only among the populations. Cluster analysis using single linkage method based on leaf and fruit characteristics showed that ten selected populations of S. commixta in Korea could be clustered into three groups. Group I is Mt. Sungin at Ulleung island, Group II is Mt. Halla at Jeju island, and Group III comprises Osan, Mt. Kaji, Mt. Duckyoo, Mt. Balwang, Mt. Sobaek, Mt. O-dae, Mt. Jiri, and Mt. Taebaek. The selection level based on major agronomic traits, which are the Number of Fruit per Fruiting Lateral(NFL) over 50, and Fruit Length(FL) and Width(FW) over 10 mm, and Weight of 100 Fruit(WFI00) over 66 g, was applied on 100 sample trees, and five trees were selected. The selection effects from selected trees in NFL, FL, FW, and WF100 were evaluated as 132%, 151 %, 142%, and 264% compared to the mean of those 100 sample trees, respectively. Especially, Ulleung 2 showed excellent values that NFL and WFI00 were 95, and 69 g, respectively, suggesting a promising new cultivar for larger fruit and high productivity.

우리나라 토지은행 제도는 토지시장 안정을 위해 토지를 사전비축하고, 이를 적시에 공급하는 국가차원의토지수급정책 유형이다. 이 논문은 실제 비축토지를 이용한 5개 단지조성사업과 10개 도로건설사업을 대상으로나누어 공익개발사업에서 토지은행에 의한 비축토지 공급의 당위성 여부와 토지보상비 절감에 어느 정도 기여할수 있는지를 실증분석 한 것이다. 연구결과는 다음과 요약할 수 있다. 첫째, 단지조성사업에서는 토지의 사전비축당위성이 불분명한데 반해, 도로건설사업에서는 토지의 사전비축 당위성이 존재하는 것으로 나타나 사업유형별차이가 있음을 입증하였다. 둘째, 도로건설사업에서는 비축토지의 일괄비축(일괄보상)을 가정할 경우, 평균 6.8% 의 토지보상비 절감이 가능한 것으로 추정되었다. 이와 같은 토지비축의 경제적 효과에 대한 실증분석결과는향후 도시재생수요 및 빈집증가 등에 대한 토지은행 대상 범위확장 시, 사업유형별 토지확보 방식의 차별화를위해 활용할 수 있을 것이다. 1. CONTENTS (1) RESEARCH OBJECTIVES In this study, the necessity and the cost saving effect of preemptive land stockpiling were evaluated for road construction and land development projects.. (2) RESEARCH METHOD This study conducted a qualitative survey on the operation of land banks in Korea and an empirical analysis on the difference between the unit cost of land compensation and the change in land price of surrounding areas during project period. For 5 land development projects and 10 road construction projects, the actual land compensation cost expenditures were compared with the estimated costs assuming lump-sum compensation at the initial point of time. (3) RESEARCH FINDINGS Since the correlation between the published price of land and the unit cost of land compensation, which are changing anually, was unclear in land development projects, the expendture patterns of purchasing land hardly justify the cost-saving effect of preemptive lump-sum compensation. However, in road construction projects, the annual variations in unit cost of land compensation showed similar patterns to the increase in published land price. 2. RESULTS The land stockpiling by land bank is a policy tool to promote public projects such as road construction and industrial complex development quickly by securing land in advance and saving costs. The result showed that, in 10 road construction projects, about 6.8% of land compensation costs can be reduced by assuming lump-sum land purchase in early stages by the Land Bank, while we cannot expect these cost-saving effects in land development projects. It seems that the lump-sum compensation method for stockpiling land is relatively effective in road construction projects, rather than in land development projects, considering the land price increase invoked by development projects. In land development projects, with a proper division of sub-areas to be purchased stepwise, even sequential compensation can be appropriate.
