This study aims to assess the disputes on Parcel boundaries and present the direction of boundary demarcation by means of investigating and analyzing the judicial fast·s related to the boundary disputes in Korea. This study is limited to the cases made by the Supreme Court and the Constitutional Court. 1250 cases are collected in the web site of Ministry of Legislation and analyzed in relation with boundary disputes to show dispute assessment and a methodology for boundary establishment. To identify the main reasons for the occurrence of the disputes, an analysis of the cases of boundary disputes that can be divided into civil, criminal and special cases has been taken and the result shows that the boundaries registered on cadastral maps contain considerable problems, the boundaries on the maps do not play its role as legal boundaries and the boundaries on the maps has not been considered in the procedures of criminal and special lawsuits as the precedent cases show, Therefore, on the basis of investigated and analyzed results, the proposed methodologies for establishing parcel boundaries are identified as follows:firstly change of the legal boundary to the ground boundary, secondly establishment of a special organization for the settlement of boundary disputes, and lastly promotion of a cadastral resurveying project by the fusion of real occupancy boundary with the map boundary.

Objective: The aim of this study was to determine whether cortical punching stimulates the expression of matrix metalloproteinase-1, -8, and -13 in orthodontic tooth movement in rats. Methods: A total of 32 male sprague-dawley rats at 15 weeks old were divided into two groups of 16 rats each, to form the tooth movement with cortical punching (TMC) group and tooth movement only (TM) group. A total of 20 gm of orthodontic force was applied to rat incisors to cause experimental tooth movement. Cortical punching was performed on the palatal side near the central incisor with a 1.0 mm width microscrew in the TMC group. The duration of tooth movement was 1, 4, 7, and 14 days. Results: Measurements of the mRNA expression were selected as the means to determine the identification of expression of MMP-1, -8, and -13. In the TMC group, the expression of collagen type I was greater than that of the TM group from day 4 to day 14. Expression of TIMP-1 in the TM group was greater than that of the TMC group in the pressure side of PDL and alveolar bone cell at day 4. In the TMC group, TIMP-1 was expressed at the osteoclast, but not at the tooth surface of the TM group at day 14. Maximum induction of the mRNA of MMP-1 was observed on day 4 in the TMC group, but it was observed on day 7 in the TM group. MMP-8 mRNA of the TMC group was twice greater than that of the TM group at 4 days. In the TMC group, maximum induction of MMP-13 mRNA was observed on day 1. Conclusions: These findings suggested that cortical punching can stimulate remodeling of PDL and alveolar bone connective tissues during experimental orthodontic tooth movement in rats. 본 연구는 피질골 천공을 동반한 교정적인 치아이동이 통상의 교정적인 치아이동과 조직 재형성의 정도에 차이가 존재하는지 알아보기 위하여 시행하였다. 실험동물은 15주령 군 300 - 350 g의 자성 백서(Sprague-Dawley Rat)를 사용하였으며 피질골 천공을 동반한 치아이동 실험군(TMC group, n = 16)과 단순 치아이동 대조군(TM group, n =16)으로 나누었다. 모든 실험동물에 20 gm 이하의 힘으로 전치부를 이개시키는 치아 이동을 시행하였으며, 실험군은 상악전치부의 직후방 구개측에서 치근을 손상시키지 않도록 직경 1.0 mm의 microscrew를 사용하여 피질골 천공을하였다. 모든 실험동물은 1, 4, 7, 14일에 희생시켜서 matrix metalloproteinase (MMP)-1, -8, -13 효소의 RT-PCR과 I형 교원질(Collagen type I)과 Tissue inhibitor of metalloproteinase-1 (TIMP-1)의 면역조직화학염색(immunohistochemistry) 을 시행하였다. MMP-1은 실험군에서 4일째에 가장 활발한 발현을 보이다가 7일째와 14일째에 조금씩 감소하는 경향을 보인 반면에, 대조군에서는 실험 7일째에 가장 높은 발현을 보이다가 14일째 들어서 감소하는 양상을 보였다. MMP-8은 실험 1일째부터 실험군이 대조군에 비해서 더 많은 발현을 보였으며, 특히 4일째의 실험군에서는 대조군보다 두 배 이상 발현되었다. MMP-13은 실험 1일째의 실험군에서 가장 높은 발현도를 보였으며, 대조군에서는 오히려 미처치 대조군에 비해 더 낮게 발현되었다. I형 교원질의 면역조직화학염색 결과는 실험 4일째부터 압박측 에서는 실험군에서 대조군보다 더 많은 교원질의 소실을 보였고, 인장측에서는 대조군이 실험군보다 더 많은 교원질의 염색 소견을 보였다. TIMP-1은 실험 4일째에는 압박측에서 대조군이 실험군보다 치주인대와 치조골의 골세포에서 좀 더 균일한 염색 소견을 보였다. 이상의 실험 결과에서 피질골 천공은 백서의 실험적 치아이동에 있어 치주인대와 치조골 결합 조직의 재형성 속도를 증가시키는 것으로 판단된다.

치아이동 시 피질골 천공이 치조골 재형성에 미치는 영향을 알아보기 위해서 생후 15주된 자성백서를 사용하여 피질골 천공 후 치아이동을 실시한 실험군(Tooth movement with cortical punching: TMC group, n = 16)과 교정적 치아이동만 실시한 대조군(Tooth movement only group: TM group, n = 16)의 치아주위조직을 면역조직화학염색을 통하여 관찰하였다. 실험군과 대조군의 실험동물에 20 gm의 힘으로 상악 전치부 사이를 이개시키는 치아이동을 시행하였으며 실험군에서는 상악 전치부 구개부위에 피질골 천공을 실시하였다. 치아이동 후 1, 4, 7, 14일째에 실험군과 대조군의 실험동물을 희생시켰다. 면역조직화학염색법으로 OPG, RANK, RANKL의 발현을 비교한 결과, OPG의 발현은 양 군 모두에서 미처치 대조군에 비하여 감소되었으나, 실험군에서의 발현이 대조군보다 컸으며, RANK, RANKL은 피질골 천공을 시행한 경우에 더 강한 발현을 보이는 것이 관찰되었다. 따라서 피질골 천공이 치주조직의 OPG, RANK, RANKL의 발현에 영향을 미치며 치조골의 재형성을 향상시키는 것을 알 수 있었다. Objective: The purpose of this study was to investigate whether cortical punching could stimulate the expression of OPG, RANK, and RANKL during tooth movement by immunohistochemistry. Methods: 34 sprague-dawley rats (15 weeks old) were allocated into 3 groups: TMC group (experimental group; Tooth Movement with Corticotomy, n = 16), TM group (control group; Tooth Movement only group, n = 16), and non-treatment group (n = 2). 20 gm of orthodontic force was applied to rat incisors by inserting elastic bands. The duration of force application was 1, 4, 7 and 14 days. A microscrew (diameter 1.2 mm) was used for cortical punching of the palatal side of the upper incisors in the TMC group. Results: Distributions of OPG, RANK, and RANKL were evaluated by immunohistochemistry. OPG, RANK and RANKL were observed on experimental and control groups. On the compression side, the degree of the expression of OPG decreased in both groups. The expression of RANK was most prominent in the experimental group of day 4. The expression of RANKL was most intensive and extensive in the experimental group of day 7. However, the expression of OPG was decreased in the experimental and control groups compared to the non treatment group. The expression of OPG, RANK and RANKL after force application were decreased at day 14. Conclusions: These findings suggested that cortical punching might stimulate remodeling of alveolar bone during a 2 week period of tooth movement without any pathologic change.

Objectives : The purpose of this study was to investigate the prevalence of erectile dysfunction (ED) in a rural area of Korea and to examine the relationship between the prevalence and correlates of subjects. Method : This study was done as a part of the chronic disease survey of rural area by the Asan Foundation. Among 30 years or older population from Jung Eup, a rural area of Korea, 711 male subjects were sampled using a cluster probability sampling method. Trained interviewers visited and interviewed subjects aged 30 years or older with a structured interview. ED was categorized as 'none', 'mild', 'moderate', or 'severe' according to the ability to 'attain and/or maintain an erection satisfactory for sexual intercourse'. Response rate was 54.3% (N=386). Results : The age weighted prevalence of ED was 27.2% (minimal 14.1%, moderate 7.6%, severe 5.5%). Prevalence and severity increased with age. Liver disease and underweight were significantly (p<0.05) associated with ED. Smoking seemed to be correlated with ED, but did not reach statistically significant level. Conclusion : ED was highly prevalent in the rural community of Korea. Medical, sociodemographic, and lifestyle variables associated with ED may alert physicians to patients at risk for ED and offer insight to its etiology.

Objective : Serum uric acid has now been identified as a marker for a number of metabolic and hemodynamic abnormalities. The aim of this study is to evaluate risk factors which influence hyperuricemia in the citizens of Asan. Method : The study design was cross-sectional and research subjects were 1086 citizens of Asan. General characteristics, cigarette smoking, alcohol consumption, and past history were obtained by interview using a structural questionnaire. Also, we measured height, weight and blood pressure, and serum uric acid of the subjects. Results : The mean serum uric acid level was 5.27 ㎎/㎗ in men and 4.01 ㎎/㎗, in women, In the multiple logistic regression analysis, statically significant risk factors of hyperuhcemia were gender, body mass index, blood lead concentration, and serum creatinine. Conclusion : Our results suggest that gender, body mass index, blood lead concentration, and serum creatinine might be the most important risk factors of hyperurcemia. Education program as well as routine check-up for serum uric acid was highly recommended for the effective prevention of hyperuricemia.

Two different modes of rolling were applied to control the texture development in tantalum sheet. In the conventional uni-directional rolling, the typical rolling textures of a body-centered cubic metal which was primarily composed of <110>//(rolling direction) was developed. In a cross rolling where the specimen was rotated by 90o between each pass, the rotated cube components, i.e. {100}<011> were greatly reinforced. The prediction of lattice rotation by the full-constraint Taylor model showed that the high stability and the symmetry of the rotated cube components caused their strengthening in cross-rolling. The two specimens were heated to 1,100℃ at 9℃/ min and held for 1 hour for annealing, then cooled to room temperature in atmosphere. In spite of the significant difference in the deformation textures, the annealing textures were very similar. They developed strong <111>// (plane normal) components with negligible intensity at the rotated cube components, which was attributed to the negligible capability of the latter components to provide effective recrystallized grains.

비육우의 공장, 회장 및 결장의 특징적 괴사 출혈성 장염 증상은 폐사 증후군과 관련이 있는 것으로 인식되고 있다. 특히 젖먹이 송아지들이 폐사 증후군에 가장 영향을 받는데, 포유시 송아지에게 과식을 시키거나, 비위생적 초유 급유, 체온 하강 및 스트레스는 장독혈증 발생의 원인들이다. 2006년 7월 중 경북 영천 지역에서 축우의 폐사가 발생하였다. 식욕부진, 의기소침, 간헐적인 설사 및 경미한 호흡 곤란을 제외하고는 특별한 임상 증상은 없었으나, 조직학적 소견에 의하면, 심장, 신장, 간, 비장 및 임파선을 포함한 각종 기관에서 globular leukocytes의 침윤뿐 아니라 핵내 봉입체가 현저하게 나타났다. 비장과 림프조직에서는 림프 괴사와 림프구 괴사로 인한 ‘starry sky appearance’를 나타내었다. 소장 점막 하에서는 다량의 globular leukocytes와 호산 구의 침윤과 함께 호 염기성 세포 집단이 관찰되었다. 봉입체가 있는 소장 조직의 단면은 그램 염색에 대해 조직 화학적으로 양성반응을 나타내었다. 결론적으로, 비축우의 폐사 원인은 조직학적 및 조직화학적 분석 결과를 근거로 Clostridium perfringens D 형균에 의한 장독혈증으로 진단되었다. Sudden deaths have occurred in feedlot cattle with marked necro-hemorrhagic enteritis of the jejunum, ileum and colon. Suckling beef calves are the most frequently affected. Over-consumption of large amounts of milk, inadequate colostrum intake, chilling and stress are conducive to the development of enterotoxemia. Enterotoxemia caused by Clostridium perfringens type D mostly occurs following a sudden change of diet, particularly to feeds made richer in order to grow the cattle to market weight in feedlots. During July 2006, sudden deaths of cattle occurred in the Youngcheon regional area of Gyeongbuk province. There were no significant clinical signs except anorexia, depression, intermittent diarrhea and mild respiratory failure. Histological findings revealed a prominent intranuclear inclusion as well as infiltration of the globular leukocytes in various organs including the heart, kidneys, liver, spleen and lymph nodes. Spleen and lymphatic tissues showed lymphatic necrosis and a starry sky appearance. In the submucosa of the small intestines, basophilic aggregation was detected with massive infiltration of the globular leukocytes and eosinophils. Gram staining for the tissue sections containing inclusions of the small intestines revealed a positive histochemical reaction. Taken together, we suggest that Clostridium perfringens type D-induced enterotoxemia is determined to be the cause of sudden death of feedlot cattle.
