Objectives : The purpose of this study was to examine the oral health knowledge and actual oral health care of the selected subjects, their decision making about prosthetic treatment, the state and characteristics of their prosthetic treatment and their satisfaction with prosthetic treatment in an attempt to provide some information on the improvement of the quality of life related to oral health and the promotion of oral health. Methods : The subjects in this study were 250 people who received education in two different lifelong education institutions in the city of Busan. After a survey was conducted from May 23 to June 15, 2011, the answer sheets from 217 respondents were analyzed. Results : 1. As for the general characteristics of the respondents, the men(52.1%) outnumbered the women. Those who were in their 60 and up(47.5%) made up the largest age group, and the married people(65.4%) outnumbered the unmarried ones. By occupation, the company employees(20.3%) made up the biggest group. By education, the greatest group was high-school graduates(36.1%). By monthly mean income, the biggest group gained an income of 2.01 million won or more(36.9%). As to medical security, community-based insurance was most prevailing (36.9%). In terms of health promotion, the largest group worked out to stay fit(52.4%). 2. Regarding oral health knowledge, they had a good knowledge about the cause of dental caries(56.7%), but they weren't well aware of the right time for regular dental checkup(47.9%). In relation to oral health care, regular scaling wasn't prevailing(16.9%). 3. Regarding connections between the general characteristics and satisfaction with prosthesis, the less-educated respondents expressed significantly more dissatisfaction(p=0.015). By monthly mean income, those who had a smaller income were dissatisfied in general(p=0.028). Conclusions : The findings of the study illustrated that it's required to spread awareness of the importance of oral health among people in general, and that differentiated incremental oral health care should be provided for different age groups. In order to raise the satisfaction of patients with prosthesis, how to relieve their pain and anxiety and how to adjust prosthetic treatment cost properly should carefully be considered. In addition, the government should take measures to offer assistance for the low-income classes in preparation for an increase in the elderly population.

Objectives : This study was performed to investigate the effects of Needle Electrode Electrical Stimulation (NEES) on ischemia-induced cerebrovascular accidents. After obstruction and reperfusion of ${\ast}{\ast}$ arteries in white mice, the amounts of necrosis and inflammation related substances IL-6, Caspase-3, and PARP, C-fos were measured in neurons of the hippocampus. The following results were obtained. Methods : This study used 21 male specific pathogen free (SPF) SD (Sprague Dawley) rats, 8 weeks of age and approximately 300 g in weight, that were given at least 1 week to adapt to the lab environment Each exposed artery was completely occluded with non-absorbent suture thread and kept in that state for 5 minutes. The sutures were then removed to allow reperfusion of blood. Test group is control group for comparison with the common carotid artery occlusion models, a GI group that underwent common carotid artery occlusion, and a needle electrode electrical stimulation (NEES) group that underwent NEES after artery occlusion. The GI and NEES groups were given 12, 24, or 48 hours of reperfusion before NEES. NEES device (PG6, ITO, Japan, 9V, current, 2Hz) was used to stimulate the right and left acupoint ST36 of the SD rats for 30 minutes while they were sedated with 3% isoflurane. An immunohistochemistry test was done on the forebrains of the GI induced rats. All the data collected from this study was symbolized and analyzed using a statistics processing program (SPSS 12.0K/PC). The level of significance was set at ${\alpha}$=0.05 and a T-TEST analysis was used to find out the effects of treatment on each of the groups: the normal group, the CVA induced group, and the treatment after CVA induction group. Results : Both PARP and C-fos immuno-reactive cells, related to apoptosis, were greater in the GI groups than the NEES group. Caspase and IL-6 immuno-reactive cells, related to inflammation, were greater in the GI and NEES groups than the control group. Conclusions : This research was conducted to study the effects of NEES on CVA due to ischemia. Occlusion and reperfusion was performed on the common carotid arteries of white rats, after which amounts of substances related to neuron necrosis and inflammation - PARP, IL-6, Caspase-3, and C-fos - were measured in the Hippocampus

A clinical study was performed on 75 cases of the esophageal cancer and benign esophageal diseases experienced at Department of thoracic & cardiovascular surgery, School of Medicine, Keimyung University during 3 year period from 1978 to 1982. Of 75 cases of the surgical esophageal diseases, there were 35 patients of the esophageal cancer. 17 patients of benign esophageal stenosis, 10 patients of esophageal perforation, 4 patients of diverticulum. 3 patients of achalasia, 2 patients of congenital T-E fistula, one of upper esophageal web, one of esophageal foreign body, one of leiomyoma and patient of hemangioma. First, esophageal carcinoma was more frequent in men than in women by a ratio of five to one, and the peak incidence occurred in the 5th to 6th decade. Dysphagia was the most common symptom in 88.6 percent of our cases. The tumor was located mostly in the middle & the lower one third [91.4%]. The histological diagnosis was made in 35 cases. The squamous cell carcinoma was the most common [82.9%] and the rest was the adenocarcinoma in the lower one third [17.1%]. Thirty-five cases were operated and resection was feasible in the twenty-five patients [71.4%] with 2 cases of hospital mortality [5.7%]. All but two of the esophageal stenosis were caused by corrosive esophagitis and ages ranged from 7 to 70 years with average age of 32 years. Corrective operations were performed on 17 patients of esophageal stenosis of whom 12 patients had esophagocologastrostomy, 3 patients esophagogastrostomy and in non-corrosive esophageal stenosis one case and esophagoplasty and another case had release of external compression. There was one complication of stenosis of the esophageal perforation were traumatic in five cases, empyema in three cases, caustics in one case and postemetic in one case. 10 patients of the esophageal perforation underwent operation: primary closure in 5 cases, two staged colon interposition in 2, esophagogastrostomy in 1 and closed thoracotomy in 2 cases There were 2 complications of leakage of anastomosis sites in postoperative period. 4 patients of traction type of diverticulum underwent diverticulectomy & 3 patients of achalasia underwent modified Heller`s operation. 2 patients of congenital esophageal atresia had distal tracheoesophageal fistula & underwent one staged operation with the results of one death caused by pneumonia. Upper esophageal web had divulsion through the esophagoscope and foreign body in upper esophagus was removed through cervical esophagotomy. One case of leiomyoma in esophagus had esophagectomy and reconstruction with right colon. And one case of hemangioma in esophagus had esophagectomy & esophagogastrostomy.

조선시대 양반가의 장례시 매장방식은 회곽묘제를 사용하였으며, 그 유물들이 현대에 형태를 유지한 채로 출토되는 경우가 종종 있다. 그러나 그 내부에서 발견되는 섬유유물들은 예전에는 염직물이었을 것으로 예상되나 오랫동안 시즙과 수분에 의해 오염되어 고유의 색상 및 물성에 변화를 일으킬 수 있다. 이러한 오염은 출토 후에도 계속적으로 유물의 변퇴색 및 열화에 영향을 미칠 것으로 예상되므로 적합한 세척이 요구된다. 따라서 본 연구는 습식세척 후 출토염직물의 색변화를 최소화할 적합한 세정조건을 조사하기 위하여 적색계 7종, 청색계 1종, 황색계 6종, 녹색계 4종, 자색계 4종의 천연염색 염색포(견과 면)을 만들어서 이를 돈육과 함께 6개월간 냉장보관한 후 꺼내어 물, 음이온계면활성제(SDS), 비이온계면활성제(TritonX-100), 천연계면활성제(Saponin) 등 4종의 세정액를 이용하여 $20^{\circ}C$와 $40^{\circ}C$의 온도에서 습식세척하여 염직품들의 색상변화에 대한 영향을 조사하였다. 그 결과 색상의 변화는 세정온도, 섬유소재, 세정제, 이용한 염료의 종류에 따라 차이를 나타내었다.

본 연구는 극한치 이론을 적용하여 국내 주식시장에 대한 VAR값을 구하고 이의 유용성을 살펴보았다. 극한치모형으로는 블록최대값모형과 POT 모형을 이용하였고 백테스트를 통하여 이들 모형의 적정성을 알아보았다. 극한치모형 중 블록최대값 모형은 신뢰수준의 변화에 따라 VAR 추정치의 변동이 매우 큰 것으로 나타났으며, 블록의 크기를 어떻게 선택하는가에 따라 모수의 추정치가 크게 달라져 VAR값의 안정성이 떨어지는 것으로 나타났다. 이는 국내 주식시장에 대해 VAR 측정시 블록최대값 모형을 사용하는 것은 적절치 않음을 시사하는 것이다. 반면 POT모형은 임계치의 선택에 따라서 VAR 값이 달라지기는 하나 상대적으로 안정적인 모습을 보이며, 또한 백테스트 결과 97.5% 이상의 신뢰수준에서 VAR값이 델타 VAR에 비하여 우수한 성과를 보이는 것으로 나타났다. 특히 POT모형은 신뢰수준이 높아질수록 그 우월성이 높은 것으로 나타나, 주로 99% 이상의 높은 신뢰수준의 VAR값을 이용하는 경우에 위험의 관리수단으로 유용한 모형임을 시사하고 있다. 또한 극한치모형은 수익률의 왼쪽 꼬리와 오른쪽 꼬리를 분리하여 추정하고 이를 VAR의 계산에 이용하기 때문에, 수익률분포가 비대칭적 특징을 보이는 우리나라 주식시장의 VAR 측정시 적절한 방법임을 확인할 수 있었다.

In order to investigate the pharmacological properties of New Woohwangehungsimwon Pill (NWCH). Effects of Woohwangehungsimwon Pill (WCH) and NWCH were compared using various experimental models. In isolated rat aorta, NWCH and WCH showed the relaxation of blood vessels in maximum contractile response to phenylephrine ($10^{-6}$M) without regard to endothelium containing or denuded rings of the rat aorta. Furthermore, the presence of the inhibitors of NO synthase and guanylate cyclase did not affect significantly the relaxative effects of NWCH and WCH. NWCH and WCH inhibited the vascular contractions induced by acethylcholine, prostaglandin endoperoxide or peroxide in a dose-dependent manner. In conscious spontaneously hypertensive rats(SHRs), NWCH and WCH decreased significantly heart rate. These, at high doses, had a negative inotropic effect that was a decrease of LVDP and (-dp/dt)/(+dp/dt) in the isolated perfused rat hearts, and also decreased the contractile force and heart rate in the isolated rat right atria. In excised guinea-pig papillary muscle, these had no effects on parameters of action potential at low doses, whereas inhibited the cardiac, contractility at high doses. Furthermore, these had a significant inhibitory effects on heart acceleration in normotensive rats and SHRs. These results suggested that NWCH and WCH have weak cardiovascular effects, and that there is no significant differences between two preparations.

현 시대에 사는 사람들 중에 다수는 자의적이거나 타의적인 이유로 결혼을 하지 않거나 독립하여 혼자 생활하는 것을 선호하고 있고 그 이유로는 크게 타인에게 간섭받기 싫어서 또는 경제적 사정 등이 있으며, 특히 자신만의 편안한 생활을 추구하는 직장여성들이 일인 생활을 선호하는 추세이다. 하지만 이러한 점을 타겟으로 하여 악용하는 범죄의 표적이 되기도 한다. 그로인하여 현관문 등에 안전고리 등과 같은 보안장치를 추가 장착하여 사용하기도 한다. 현관문의 안전고리를 잠그는 행위는 그렇게 어려운 일은 아니지만 쉽게 잊어버릴 수 있고, 취침 전 잠자리에 위치하여 있을 때 안전고리의 잠금 여부를 확인하거나 잠가야할 때 다시 일어나서 현관으로 이동해 안전고리를 확인하고 잠가야 한다. 하지만 그 번거로움과 불편함으로 괜찮겠지 하는 마음에 안전고리를 채우지 않을 때가 많다. 본 논문에서는 이러한 번거로움을 해결하고 보다 안전한 생활을 유지하기위한 방법으로 스마트 폰을 이용하여 원격에서 안전고리를 조정할 수 있는 장치를 설계 및 구현하여 보다 편하게 안전고리를 사용하여 불법주거 침입 등의 범죄로 부터 안전을 도모 하고자 한다.

Purpose: The purpose of this study was to develop a new fall-prevention exercise intervention for the community-dwelling elderly and to examine the effects of program. Methods: A total of 7 older adults were participated in a 10-week fall-prevention exercise intervention (1 day per a week in community centers, 2 days per a week in a home). The exercise program consisted of warming-up, extension exercises, muscle strength exercises, balance exercises, and finishing exercise. Data were collected before the exercise and after 10 weeks of exercise. In this study, muscle strength of lower limbs was measured by 10 times of standing up and sitting on a chair. Static balance was measured by one-leg standing, and dynamic balance was measured by 6 meter walking. Results: After a 10-week exercise program, muscle strength of lower limbs (t=4.18, p<.05), statical balance were significantly improved (left leg, t=-3.11, p<.05; right leg, t=-4.56, p<.05). Seven of 11 items measuring fear of falls were significantly decreased (p<.05), and dynamic balance tended to be improved (p=.117). Conclusion: This result suggests that evidence-based, fall-prevention exercise program can improve muscle strength, static and dynamic balance, and fear of falling in the community living elderly.
