The purpose of this study is investigating the effects of combination of policosanol intake and combined exercise to the defence mechanism and the changes of fat cell control hormones by analyzing the changes of inflammatory markers LDH and CPK, and Leptin when having policosanol intake and combined exercise together against obese women for 12 week. These groups are randomly assigned to the control group, policosanol intake group, combined exercise group and combined treatment group with 12 obese women in esch group and they performed muscular resistance exercise and an aerobic exercise which was walking twice a week. After 12 weeks the LDH showed significant differences(p<.01) at exercise period, and also showed the significant differences(p<.05) in the effect of the interaction between exercise period and group. The changes in Leptin showed significant differences(p<.001) at exercise period. In summary, carrying out together of the aerobic exercise, muscular resistance exercise or policosanol intake can be considered to have the beneficial effects to prevent various disease which caused by inflammatory maker and Leptin and it also increases its effects.

We face with numerous situation of decision making. In this situation, we would make decision through individual's own information, or others' decision making with ignoring private information, Also we would make decision through compromise of private information and others' information. like this, we call situation to imitate information of previous decision maker, with disregarding private own information,'information cascades' Also, anchoring effects are results of insufficient adjustment from an arbitrary value. In this paper, we examined how information cascades effects and anchoring effects would be generated in the people who use IT technique as instant poll of website. And this paper presents alternatives to decrease information cascades effects and anchoring effects. This exercise provides facts anchoring effects occur when voters can see poll result. And this paper shows that more degree of output difference is deepened, and more anchoring effects occur. Also this paper shows that when website gives positive payoff, more anchoring effects occur.

Unstable fractures of the proximal humerus continue to be difficult problems for orthopaedic surgeons. The optimum treatment of these fractures has remained a matter of controversy. We analyzed the clinical results of open reduction and plate fixation underwent for patients of unstable fractures of proximal humerus after minimum 12 months follow up. The purpose of this study is to evaluate the efficacy of open reduction and rigid plate fixation. Twenty-two patients were managed with open reduction and plate fixation. Mean follow up duration was 20.6 months(range, 12 to 28 mon.). Because the age of patient as a maker of degree of osteoporosis was considered the key factor in the success of anatomic reconstruction, we divided into two groups according to age. Group A was comprised of 12 cases with younger than 50 yrs of age. Ten cases of older than 50 yrs of age were Group B. According to Neer's classification, five cases(22%) were two part fracture, 12 cases(64%) were three part fracture, and three cases(14%) were four part fracture. We used the Neer rating system for evaluating the results. In Group A, overall scores were 79.1. In Group B, overall scores were 76.8. Overall scores in two part fracture were 85, overall scores in three part fracture 78.4 and overall scores in three part fracture 68.3. We achieved excellent or good results in nine cases(75%) of Group A and seven cases(70%) of Group B. Also, we obtained excellent or good results in all cases of two part fracture, ten cases(71%) of three fracture and one case(33%) of four part fracture. The complications were three metal loosening, one avascular necrosis of humeral head, one severe stiff shoulder, one superficial wound infection and one ectopic ossification. The results were excellent or good in 16 cases(73%) out of 22 cases. In conclusion, rigid fixation and supervised early exercise would be a good option for unstable fracture of the proximal humerus.

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.

The Tech Shop, which provides an environment for fast prototyping by using 3D printers and various work tools, is a place where the fusion design education can be realized and creative ideas can be produced in the era of industrial 4.0. The purpose of this study is to propose and establish the possibility of a tech shop for the revitalization of local businesses in the Chungcheong province where many of contents related universities and institutions are located. For this purpose, we reviewed the necessity and the requirements of a tech shop, and analyzed the necessary components of a tech shop for successful operation. If the proposed tech shop is built and efficient operation is applied, it is expected that many of prototypes based on good ideas could be quickly produced and commercialized.
