Occlusive coronary artery disease presents a potential threat to a significant population in the United States. According to many case reports, the increasing incidence of coronary artery disease due to atherosclerosis is noted in Korean, recently. Operative vascular procedures have increased steadily in number over the past 20 years in the United States. There have been many isolated case reports about coronary artery surgery, but these had little clinical impact. Nowadays, major three coronary bypass surgery has developed principally at three cardiac centers in the United States since 1967. Among three coronary bypass operation, the aorta-coronary artery saphenous vein bypass graft was first demonstrated by Favolaro and Effler at the Cleveland Clinic in 1967. We experienced one case of coronary artery disease, which was treated successfully by aorta-coronary saphenous vein graft with mild hypothermia under extracorporeal circulation in May, 1977. Saphenous vein was removed from above the knee and was 2.5 mm in diameter. The left ventricle was not vented for the left ventricle was not overdistended. Temporary artificial pace-maker-Medtronic-was implanted for the prevention and treatment of post-operative arrhythmia and heart block in post-operative first day. He is a 57 year old male businessman who had been suffered from hypertension [200 mmHg in systolic pressure] since 4 years ago, who had intermittent conservative treatment at local clinic. He had been afflicted with severe chest pain with choking sensation for 50 days. This symptom was aggravated exposing cold weather, or cold water, but was respond to rest. Pre-operative ECG revealed no any other ischemic sign except sinus bradycardia. Significant S-T segment depression was noted at lead II, AVF after double 5 minutes exercise, indicating positive Master`s test. Serum cholesterol was slight elevated to 253 mg/dl. Final pre-operative diagnosis was made by coronary arteriogram, which showed about 1.0-cm segmental 90 % occlusive atherosclerotic lesion in the proximal part of right coronary artery above the origin of acute marginal artery. Left coronary artery revealed good patency and there was no collateral circulation between right and left coronary artery .Hospital course was not eventful. He was discharged with good result on the post-operative day. He has been free from chest pain for longer than 2 years. And also the arterial flow in the coronary bypass graft is auscultated with the pocket-sized ultrasonic velocity detector, which shows the patency of the coronary bypass graft good.

Background: This study aimed to compare the effectiveness of the pericapsular nerve group (PENG) block and intra-articular injection (IAI) of steroid-bupivacaine in the treatment of hip osteoarthritis (OA). Methods: After randomization, patients received either a PENG block or IAI under ultrasound-guidance. Clinical evaluations were recorded at baseline, day 1, and weeks 1, 4, and 8 post-intervention. The numerical rating scale (NRS), Western Ontario and McMaster Universities Arthritis Index (WOMAC), Harris Hip Scale (HHS) scores, pain medication use determined by a quantitative analgesic questionnaire, and patient satisfaction were evaluated. Results: Sixty patients were included in this study. NRS scores improved significantly for both groups during the follow-up compared to pretreatment (P < 0.001), with better pain scores for the PENG group (P < 0.001) at day 1 with larger effect size (Cohen's d = 4.62), and IAI group at 4 (Cohen's d = 5.15) and 8 (Cohen's d = 4.33) weeks (P < 0.001). There was no significant difference in pain medication consumption (P = 0.499) and patient satisfaction (P = 0.138) between groups. Patients in the IAI group experienced significant improvement in HHS (Cohen's d = 2.16, P = 0.007) and WOMAC (Cohen's d = 1.02, P = 0.036) scores at 8 weeks compared to the PENG group. Conclusions: The ultrasound-guided PENG block provides effective pain relief which improves functionality and quality of life in hip OA patients up to 2 months. The PENG block can be considered an easy, safe, and useful alternative treatment modality for hip OA.

Purpose: The effects of aroma massage on pain, activities of daily living, and fatigue were investigated in the patients who have knee osteoarthritis. Method: A quasi-experimental design with non-equivalent control group pretest-posttest measures was used. Twenty one and twenty subjects were included in control and experimental group, respectively. Subjects in experimental group had aroma massage which used lavender, chamomile, and ginger oil on painful knee. They were encouraged to implement aroma massage at least two times a day for 2 weeks. Subjects in the control group had conventional oil massage implementing by exactly same method as did in the experimental group. GRS(graphic rating scale), Korean version of WOMAC (Western Ontario and McMaster) osteoarthritis index, and MAF(multidimensional assessment of fatigue) were used to measure the outcome variables such as pain, activities of daily living and fatigue, respectively. Results: After 2 weeks, those in the experimental group reported significantly less pain and fatigue and better activities of daily living than those in the control group. Conclusion: Based on these results, aroma massage could be recommended as a self managed intervention for the patients with knee osteoarthritis.

평택(아산)항의 내항에 대한 항만형식은 1990년 '아산공업기지 항만계획 기본계획용역'에서 갑문식으로 채택되었으나, 2001년 '평택(아산)항 종합개발 기본계획 정비용역'에서 감조식으로 변경되었다. 따라서 서해대교 하부에 건설된 남측호안이 철거되어 내항을 입${\cdot}$출항하는 선박은 상시 통항이 가능하게 되었다. 그러나 서해대교 하부의 통항 안전성을 고려할 때 내항의 통항여건은 통항가능 최대 규모선박이 단독통항을 전제로 한 50,000 DWT급이며, 교행 가능한 겉박이 3O.000 DWT급 이하라는 제약을 가지고 있다. 이에 본 연구에서는 평택(아산)항의 남측호안이 철거된 후 내항의 전망된 물동량을 처리하기 위한 연간 입${\cdpt}$출항 선박 척수를 가정하고 이러한 통항제약 상황에서 이들 선박들이 내항을 입${\cdot}$출항함으로써 발생되는 교통혼잡도를 예측하고 평가하였다. 평택(아산)항의 내항에 대한 교통혼잡도는 서해대교를 통항하기 위해 2006년 0.04(h), 2011년 0.17(h), 그리고 2020년 0.4(h)의 평균대기시간이 소요될 것으로 예상되어 통항의 지장이 크게 발생되지 않을 것으로 판단되었다.

I hereby have gained the following results by investigation and classification according to the contents of Masterial theses of 1015 volumes and Doctorial theses of 288 volumes, which have collected at their central libriaries, of theses which have published, until 1991, at Oriental Medical College of Kyunghee Univ., Kyungsan Univ., Dongguk Univ. and Taejon Univ. 1. The laboratory theses are more plentiful in number than those of literatural or clinical ones, especially more outstanding trends in the case of doctors. 2. In clinical theses, clinical obserbation was high frequnt in master and accupunture in doctor. 3. In laboratory theses, the usage of pharmacy was more frequnt than that of accupuntures or moxibutions. 4. In laboratory theses, it was more plentiful the case of being taken ill before experiment. 5. In experimental method, the drugs were more used complexed or complexed extract, in the case of accupunture, the methods were more adopted by general accup. and aqureaccupunture. 6. In laboritory theses, theses was abundant of no description of normal, control and laboratory groop. 7. It was the great number wi thin a day in the laboratory terms, the rats were most adopted as the objects of lab., in the number of lab method, doctor's was more plentiful than master's. 8. In literatural theses, there was expressed high frequnt trends of study of china, in era, Chosun dynasty in korea and Jin-Han in china. 9. The theory and books were mainly adopted as objects of theses study in the field of literature. 10. In another theses, there was many investigation of contents and drug and sign of illness were main object of study. 11. Laboratory theses had totally more reference and quotation than those of other theses. According to the above results, the number of laboratory theses are superior than clincal and literature theses, other study or statistical theses. But unfortunately they were not enough the transmission of meaning of theses and contribution of learning, beacuse how to do theses was not uni form and description was not evident. So afterward I think it is needed more careful attention and study in the method of theses works.

Now in order to overcome the weakest points of the rural areas of the city of Kimje and, transform them into rural cultural villages which have local governing systems suitable to new localization age and activate this plan, we selected Daesan Village as a model village which had shown a lot of potentials in the basic research and studied it dividing it into the former part and the latter part. We studied Daesan village in the former part focusing on state analysis and basic ideas and in the latter part focusing on master plan and detail planning. We can summarize the conclusion like the followings. 1. Daesan Village located 8 kilometer away from the downtown Kimje and the city of Iksan respectably has comparatively good environment of good sunny place as an open field whose surrounding configuration of the ground consists of farming lands and low hills in front and rear. It has 38 farming households in all. 2. Human environment(인문환경); the village road whose width is about 4 meters is forming a flow system forking off into three. There is a route bus which operates three times a day even into the inside of the village. The main sources of revenue are vegetables in facilities, fruits and floriculture. Their average revenue is about 10.5 million won. 3. Here in DaeSan Village a legend dealing with Teasan literally meaning a big mountain consist of th village's tradition and you can see the tombs of a very faithful son and Anwi an army general in the age of the Japanese Invasion of Korea of 1592 to 1598 inside the village. 4. 85 out of the eitire population 141 whose age are over 20 showed very positive attitudes in a questionnaire about, making the village a cultural one and its development. 5. The basic of planned ideas is to increase the revenue of the farming household by making the village a professional farming one which has a state-of the-art production facility and agricultural technique. It is to make the village the one where people can enjoy the sense of the rural life and the farmer can enjoy their lives through consumptive and consistant leisure and resting activities. 6. We are planning to make entrance space, life space, rest and sport space, and cultural space considering the characteristics of the village and the demand of the resident. We are also planning to make tile entire city of Kimje an information transmitting base in short and long term perspectives. 7. DaeSan Village was planned as a place where tradition and the future exist together. On the basis of this concept we planned future programs for Daesan Village and in the latter part of the study master plans and detail plans will be continued.the regional agricultural condition. The development permissions were only during the period of restricted to use ($1979.12{\sim}1993.11$). We propose that the authority of development permission should be given to the local autonomy government, because the local government has the knowledge of its individual agricultural conditions.

자동차의 증가에 따른 사고는 꾸준히 증가하고 있다. 교통사고로 인한 사망자수를 줄이기 위해 많은 안전정책이 추진되고 있으며 교통사고 사망자수를 제로로 만들기 위한 노력이 계속되고 있다. 2016년에 수립된 「제3차 교통안전기본계획」에 따르면 안전시설에 대한 개선사업은 누적사망자수가 가장 많은 지역을 우선으로 하도록 되어있다. 이는 시에서 관할하는 도로의 경우 어느 정도 합당한 방법이기는 하지만 구에서 관리하는 20m미만도로의 경우 사망자수가 기준치에 크게 미치지 못하는 현실에서 단순히 사망자수가 많은 지역을 위주로 개선방안을 내는 것은 합리적이지 않을 수 있다. 또한, 사망사고의 발생 원인이 특별한 안전시설이나 제도의 미비 때문인지 우연의 발생인지를 알아내기에는 사고건수가 상대적으로 미미하기 때문에 전체 사고를 기준으로 하는 것이 장래 더 많은 효과를 볼 수 있는 개연성이 있다. 본 연구는 사고비용을 토대로 사망사고 발생지역과 사고다발지역에 대한 비용분석을 통하여 이를 비교하였다. 3개의 산정방식을 이용한 사고비용 분석결과 모든 교통사고의 비용이 포함되었을 때에 사망자수가 없는 신촌네거리의 비용이 기존에 사고누적지역으로 채택된 시온보육원입구 삼거리의 비용보다 높게 나타나는 것으로 나타났다. 연구결과를 고려했을 때 교통사고 누적지점 선정 시 사고에 따른 비용, 사고 심각도에 대한 가중치 등을 고려하여 지점을 선정할 필요가 있다.

Objectives : Periodontal disease is a serious oral disease that frequently occurs among adults. The objective of this study is to provide necessary data for the development of an oral health care program that can effectively manage periodontal disease and subsequently maintain and enhance oral health. Methods : Data was collected from patients of a dental clinic in Daejeon, Korea from 1 July to 25 August 2009. A thesis submitted to the Committee of Graduate School of Public Health & Biotechnology Chungnam National University in partial fulfillment of the requirements for the degree of Master of Public Health conferred in February, 2010. Results : 68% of the patients were aware of periodontal disease, with older patients exhibiting better awareness. 48.0% replied that their periodontal health is good in general, with older patients inclined to say that their periodontal health was poor. 70.5% cited bad brushing habit or skipping the act of tooth brushing as the cause of periodontal disease, while 63.5% reported brushing their teeth an average of 3 times a day. 56.5% said that they brush their teeth correctly, and 63.5% told that they brush their teeth up and down, and left to right and 70.0% replied that they would attend an educational program for the prevention of periodontal disease, with older patients shown to more likely attend such a program. Conclusion : a program that can motivate people to become aware of the importance of oral health care should be developed and implemented. Such a program should include the dissemination of correct and accurate oral health care information and measures for educating people about the importance of prevention.
