There have been a lot of studies about Han-Ok, the Korean-style house, in the perspective of existing Han-Ok’s inheritance, but there are no practicality in supply of Han-Ok. The cause is considered the complexity of Han-Ok construction techniques and higher construction expenses comparatively by processing in the restricted range by the shortage of the manufacturing technology of materials. On the contrary, for evolution to the new Han-Ok that can be supplied to the present period, there are studies that is analyzed the connection between sub materials and for possible modeling by formulating of assembling way. Thus, this study try to suggest the CNC process for new Han-Ok construction to secure construction relate to construction technique, which is determined by few expert technicians that is pointed out as problems of Han-Ok.

동아시아 도성의 공간구조에 있어서 문화적 차이에 관한 연구

한경호(Han, Kyoung-ho),이영(Lee, Young) 가천대학교 아시아문화연구소 2013 아시아문화연구 Vol.29 No.-

도시는 인간이 어떠한 목적을 위해 2차원의 지도 위에 의도적으로 그려나간 인공적인 공간이다. 그러나 그 의도와 목적이 그려진 2차원의 지도가 3차원 공간인 지형 위에 가시적으로 구체화되어야 하므로 도시는 건설되는 장소와 분리하여 생각할 수 없다. 한 장소는 다른 장소와 같을 수 없고, 장소가 가지고 있는 지리 체계와 경관 그리고 그것이 결합하여 만들어내는 고유한 감각, 즉 장소성은 다른 장소에 복제되거나 이식될 수 없다. 따라서 장소는 경험과 인식에 의해 결정되는 것으로 이는 곧 문화적인 것임을 의미하며 장소 선택에 관한 문제와 장소의 해석에 관한 문제 역시 문화적 배경과 연관된 고유한 특성에 의해 결정되는 것이라 할 수 있다. 동아시아에서 도성이 들어설 장소를 획득하기 위하여 크게 중심축을 설정하는 방법과 중심점을 설정하는 방법이 확인된다. 전자의 방법은 대지에 중 심축을 설정함으로서 장소성을 부여하며, 후자의 방법은 장소성을 가진 대지를 점유하기 위한 방법으로 사용되었다. 또한 전자는 주로 중국의 도성에서 후자는 주로 한국의 도성에서 확인된다. 그러나 중심축을 설정하는 방법에는 문화적 차이가 있어, 한(漢)문화 중심의 한계(漢系)왕조의 도성과 비교하여 비한계(非漢系) 왕조의 도성에서는 방형(方形)의 평면형태와 대칭구성의 기준선으로서 중심축을 설정하는 경향이 강하게 나타나고 있음을 알 수 있다. 도시는 과거의 어느 지점으로부터 연속되어 내려오는 공간으로 역사 속의 도시를 탐구하는 작업은 현재를 이해하는 일임과 동시에 수많은 변화 속에서 변하지 말아야 할 장소의 가치 체계를 판별해 내는 작업일 것이다. City is artificial space drawn intentionally for specific purpose by human on the two dimensional map. However the map has to be realized on topology, the three dimensional space, and city cannot be thought without place.<br/> One place cannot be same with another place. Sense of place; specific sense combined with geographical conditions and landscapes; can't be duplicated to the other place. Therefore place defined by experience and perception means cultural dimension and the matter in terms of choosing and analyzing a place is also defined by a specific characteristic based on cultural background.<br/> In Asian Capital city plans, it was researched that two methods to specify the center in a city; one was making a central axis to define placeness and the other one was pointing a center to occupy meaningful place. the former was mainly checked among Chinese ancient cities and the latter was checked among Korean ancient cities. However the ways to set a central axis had cultural differences; comparing with Chinese Han, in non-Chinese Han's cities, a central axis was drawn as a baseline to symmetric organization in square-shaped city plan.<br/> City that we live in is from the past regardless of the depth of time. To study ancient city structure has the meaning for discover the unchangeable value of places.

이준한 ( Jun Han Lee ),김경호 ( Kyoung Ho Kim ) 충북대학교 건설기술연구소 2015 建設技術論文集 Vol.34 No.1

파일 주변에 발생하는 세굴을 감소시키는 방법은 크게 1)세굴에 대한 해저 지반의 저항력을 증가시키는 방법과, 2) 세굴을 일으키는 요인(하강류, 말굽형 와류, 배후류 등)의 흐름을 차단함으로서 세굴 유발능을 감소시키는 두 가지 방법으로 대별된다. 본 논문에서는 파일에 원형 반사판을 설치하여 접근 흐름의 하강 유속을 감소시켜 세굴을 억제하는, 후자의 방법에 대하여 실험적 연구를 수행하였다. 사용된 파는 주기와 파고를 각각 달리하는 정현파를 이용하였고, 세굴 방지공은 방지공의 간격파 부착되는 방지공익 개수를 변화시키며 감소 효율을 측정하였다. 측정된 감소공의 각각의 효율파 KC 수와의 상관성을 검토하여 최적화된 방지공의 구성을 분석하였다. 실험결과, 평균 감소율은 36.8%였으며, 가장 효과적인 세굴방지공은 두께와 간격비가 0.25일 때,평균 감소율이 52.3%였다. There are two methods to protect the damage of the scour around a pile. One is the method of increasing resistance of seabed, and another is that of controlling flow causing scour such as down flow, horseshoe vortex and lee-wake vortex. The former is to place protecting layer using riprap or tetrapod around a pile. The latter is to install protection devise. Experiment of the reduction of scour around a pile using protection wing are carried out under regular wave. Experiments are performed with the variation of the breadth and interval of the protection wing, wave periods(T) and wave heights (H). The each experiment shows that protection reduces the scour depth. Using the experimental results, combination of breadths and intervals the protection wing is found. Finally, the correlations of relative scour depth and KC number were analyzed. The average reduction of the scour depth by the protection wing is 36.8%. The breadth - interval ratio of protection wing was found to be 0.25 for the best combination, in which average scour depth reduction was 52.3%.

This paper described a collaborative exercise intended to see what kinds of short tandem repeat (STR) loci are used in different DNA typing laboratories in Korea and to compare their results for the demonstration whether uniformity of DNA profiling results from different laboratory could be achieved in Korea Laboratories were asked to test five tissue DNAs using methods routinely used in each laboratory and to report the results to the coordinating laboratory. The exercise demonstrated that each laboratory was using different STR loci for the typing with different STR numbers,2 VNTRS,36 STRs and amelogenin in total, and the direct comparison of the results from all the laboratory for the 18 loci could not be done as only one laboratory submitted typing results. Among 21 loci for which several laboratories submitted typing results, results for 14 loci were the same and results for the other 7 loci were different depending on the participating laboratory. D1S80, F13A01, D16S539, D21S11, D18S51, D3S1744 were the loci with different typing results. Even in the cases where commercial kits were used, the results were not the same depending on the machines used, that is the capillary electrophoresis or the gel based electrophoresis. The reason for the different results, points about the standardization of the methods arid the profiling data were described.

Heat stroke is a life-threatening illness characterized by an elevated core body temperature that rises above 40% and central nervous system dysfunctions that results in delirium, convulsions, or coma. Heat stroke is subdivided into two forms, classic and exertional. Since strenuous exercise is one of the major exacerbating and precipitating factors, the incidence of exertional heat stroke is high among young adult, especially military personnel undergoing military training. Exertional heat stroke commonly causes rhabdomyolysis, lactic acidosis, acute renal failure, shock and pulmonary edema. We report a case of heat stroke with rhabdomyolysis, acute renal failure, disseminated intravascular coagulopathy(DIC) after strenuous exercise. A 18 year old man was admitted to the hospital because of loss of consciousness. He was a wrestler and he had tried to lose 6kg in weight by jogging and strenuous exercise on that summer day with hot temperature. The development of this illness was favoured by much clothes inappropriate for that environmental condition with a purpose to enhance sweating, and by restricted intake of water and food. On admission, the blood pressure was 80/50mmHg, and body temperature was 39.4℃ with stuporous mentality. Laboratory finding were as follows : in complete blood cell count, hemoglobin was 16.7g/dL and platelet count was 158,000/ mm³. In blood chemistry, AST 1061U/L, ALT 201U/L, BUN 30mg/dL, Cr 2.2mg/dL, LDH 941IU/L, CK 696IU/L were resulted. In arterial blood gas analysis, pH 7.39, pCO₂ 30mmHg pO₂ 86mmHg, HCO₃ 18.4mEq/L, O₂ saturation 96.7% were resulted. In urinalysis, specific gravity 1.025, protein 3+, erythrocyte 2+ were resulted. In brain imaging study, brain CT finding was normal. After appropriate treatments with rapid cooling, hydration and supportive care, he improved with alert mental status. On 2nd hospital day, in laboratory result, thrombocytopenia and coagulopathy were appeared and renal insufficiency was aggravated. So he was treated with platelet concentrate and fresh frosen plasma for DIC, and enough hydration for appropriate urine volume preservation. After all, On 22nd hospital day, he fully recovered and discharged. Nowadays, with followed for some duration, he is wellbeing with no complications.

김연천,전옥경,양혜란,최영희,한선희,이강문,Kim, Youn-Choen,Chun, Ock-Kyoung,Yang, Hae-Ran,Choi, Young-Hee,Han, Sun-Hee,Lee, Kang-Moon 한국식품위생안전성학회 2000 한국식품위생안전성학회지 Vol.15 No.3

한강 고수부지 및 지천인 안양천, 탄천, 중랑천변의 경작지에서 채집된 36종 285건의 농작물에 대한 Pb, Cr, Cd, Fe, Zn, Mn, Cu. Hg의 농도를 측정하고 그 결과를 채집 시기, 채집 지역 및 작물별로 비교, 분석한 결과, 작물 중의 중금속 함량은 평균치를 기준으로 볼 때 Fe(34.592 ppm)>Mn(11.071 ppm)>Zn(8.853 ppm)>Cu(1.795 ppm)>Cr(0.237 ppm)>Pb(0.100 ppm)>Cd(0.011 ppm)>Hg(0.003 ppm) 순으로 곡류 및 두류에서는 Zn의 함량이 Mn보다 높고, 채소류와 과실류에서는 Mn의 함량이 Zn보다 높은 양상을 나타냈다. 또한 각 지역에서 채취한 작물의 미량금속 함량의 경우 Fe은 0.004∼203.083 ppm, Cu은 0.017∼22.727 ppm. Mn은 0.000∼74.373 ppm. Zn은 0.080∼37.166 ppm으로 비교적 고농도로 존재하고 있는 반면 유해중금속류인 Pb은 0.000∼0.654 ppm, Cd은 0.000∼0.270 ppm, Cr은 0.000∼l.229 ppm, Hg은 0.000∼0.037 ppm으로 비교적 미량으로 존재함을 알수 있었다. 대상 농작물을 잎, 줄기, 뿌리, 열매로 분류하여 미량금속 함량을 분석한 결과, 분석 대상 금속의 농도가 잎>줄기>뿌리>열매의 순으로 나타났다. 무등의 뿌리 작물에 있어서 Pb은 잎(0.055 ppm))뿌리(0.035 ppm), Cr은 잎(0.118 ppm))뿌리(0.031 ppm), Cd은 잎(0.004 ppm)1뿌리(0.001 ppm), Hg은 잎(0.004 ppm))뿌리(0.001 ppm)으로 뿌리보다 잎에 많은 것으로 나타났는데 이러한 결과로 보아 뿌리는 금속 이온이 흡수되는 기관일 뿐 축적은 잎에 비해 상대적으로 적게 됨을 알 수 있었다. This study was conducted to determine the content of trace metals in crops cultivated in Han-riverside, Anyang stream, Tan stream, and Jungryang stream. Trace metals (Pb, Cr, Cd, Fe, Zn, Cu, Hg) were detected in 36 crops, 285 samples by Atomic Absorption Spectrophotometer and Mercury Analyzer. The average concentration of trace metals in crop samples was in the order of Fe (34.592 ppm)>Mn (11.071 ppm)$\geq$Zn(8.853 ppm)>Cu(1.795 ppm)>Cr(0.237 ppm)>Pb(0.100 ppm)>Cd(0.011 ppm)>Hg(0.003 ppm). In crop samples, the contents of Fe, Cu, Mn, and Zn, which ranges were 0.004-203.083 ppm, 0.017~22.727 ppm, 0.000~74.373 ppm, 0.080~37.166 ppm, respectively, were relatively higher than those of Pb, Cd, Cr, and Hg, which ranges were 0.000~0.654 ppm, 0.000~0.270 ppm, 0.000~l.229 ppm, 0.000~0.037 ppm, respectively. The concentration of trace metals in crop samples was in the order of leafy vegetables > stem vegetables > root vegetables > fruity vegetables. In the root vegetables, such as radish, the content of Pb was leaf(0.055 ppm)>root(0.035 ppm), that of Cr, leaf (0.118 ppm)>root(0.031 ppm), that of Cd, leaf(0.004 ppm)>root(0.001 ppm), that of Hg, leaf(0.004 ppm)>root(0.001 ppm). As the results, it could be thought that root is the organ which doesn't accumulate the heavy metal ions, but absorb them.

Backgrounds and Objectives: Vascular dementia is a group of dementing disoders arising from various stroke syndrome. Among these. subcortical ischemic vascular dementia (SIVD) is regarded as a relatively distinct clinical entity. However, MRI patterns of SIVD are not homogenous. In some patients, lacunes are dominant, and in others, subcortical white matter changes are. This study was designed to compare risk factor profiles between SIVD with and without multiple lacunes. Methods: We divided 47 subjects (22 males, mean age. 68 years) recruited from VADAPET (Multicenter Trial For Evaluation Of The Changes In the PET Images Of Subcortical Vascular Dementia Patient) study into two groups one with more than 5 lacunes in deep gray matter (lacune group) and the other with 5 or less(non-lacune group) Clinical characteristics and laboratory findings of two groups were compared. Results: Nineteen of 47 patients (40%) belonged to the lacune group. The lacune and non-lacune groups d d not differ in the following variables: age, hypertension, diabetes mellitus, hyperlipidemia heart disease, history of stroke or TIA, history of trauma or major surgery, family history of hypertension stroke, or dementia, age at diagnosis of dementia, body mass index, white blood cell count, ESR, CRP, fibrinogen, hemoglobin A1C, total cholesterol. LDL cholesterol creatinine, proteinuria, glucosuria, and microhematuria. However, male sex, smoking alcohol. hemoglobin, and HDL cholesterol were possibly associated more with lacune group SIVD than with non-lacune group (p<0 1) Multivariate analyses revealed that smoking, hemoglobin, and HDL cholesterol were independent predictors of SIVD with multiple lacunes Conclusion: Our study suggests that SIVD with multiple lacunes may be significantly different in smoking habits hemoglobin, and HDL cholesterol from SIVD without multiple lacunes.

Background: Pulmonary paragonimiasis is caused by consumption of raw or improperlycooked crustacea infected with the laval stage (metacercaria) of Paragonimus westermani. The most characteristic symptoms were rust-colored sputum and cough. Paragonimiasis causes pleural thickening or effusion in 48% of the patients. Pleuro-pulmonary paragonimiasis can be easily overlooked by physicians who do not suspect this disease in the differential diagnosis. Method: We compared the outcomes of 11 patients with paragonimus empyema managed either through thoracotomy or pig-tail catheter drain. These patients were confirmed by food history, clinical and radiological findings, and laboratory data. Results: The male and female ratio was 1.75 : 1, and mean age was 40.0 ± 13.5 years. AII patients had pulmonary symptoms such as cough or chest pain. Serum-ELISA for paragonimiasis were all positive (mean titer was 0.57). AII patients had pleural effusion in radiological findings( 2 patients had bilateral pleural effusion). All patients received praziquantel (75 ㎎/㎏/day for 3days). Two patients were treated with thoracotomy and nine patients were treated with pig-tail drain. Hospital stay were 14.5 days in thoracotomy group and 5.6 days in pig-tail group respectively, Conclusion: Compared to the conventional thoracotomy grouP, the patients with paragonimus empyema who received pig-tail catheters had a significantly-decreased period of drain in situ, were clinically improved earlier, and were discharged earlier.
