Objectives : 노인 환자들이 제공받고 있는 치과 의료서비스 만족도를 평가하여 노인 환자에게 양질의 구강보건진료 서비스를 제공하고 노인의 구강보건향상에 기여하기 위하여 실시하였다. 이와 같은 연구목적을 달성하기 위하여 노인관련 일반적 특성을 알아보고, 치과 병 의원을 이용하는 노인 환자의 만족도에 미치는 요인 및 병 의원 선택이유를 조사하였다. Methods : 서울특별시와 경기도, 경상도, 전라도 일부지역의 치과병원 및 치과의원을 이용하는 노인 환자 300명을 편의추출 하였으며, 2009년 4월 1일부터 5월 8일까지 면접 및 자기기입법으로 설문조사를 실시하였다. 설문지는 4개영역으로 구분하여 치과 의료서비스 만족도 22문항, 치과위생사의 의료서비스 만족도 14문항, 재이용 권유의사 4문항 및 일반적 특성과 치과이용에 관한 8문항으로 구성하였다. 노인환자의 일반적인 특성에 따른 치과 의료서비스 만족도, 연구대상자의 병원인지경로, 치과선택이유에 따른 치과의료서비스 만족도는 일원배치분산분석(One-way ANOVA)을 실시하였다. 치과의료서비스 만족도 영향인자, 만족도에 미치는 치과위생사 요인 등은 다중회귀분석을 실시하였다. 연구대상자의 성별과 병원내원기간에 따른 치과선택이유는 카이제곱 (${\chi}^2$) 분포를 따르는 정확검정(exact test)을 실시하였다. Results : 1. 노인환자들이 병원을 선택할 때 가족, 친척으로부터 추천을 받는 경우가 가장 많으며 이 경우 다른 인지경로에 비하여 치과에 대한 만족도가 가장 높았다. 2. 치과선택 이유에 따른 만족도를 비교하였을 때 첫째, 의사의 높은 진료수준, 둘째, 친절한 서비스에 만족도가 높았다. 또한 치과선택이유가 의사의 높은 진료수준과 친절함을 포함한 의사요인이 가장 중요한 것으로 나타났다. 3. 치과위생사의 높은 진료수준과 친절도는 치과의료서비스 만족도에 유의한 차이를 나타내었다. 노인환자들의 만족도를 높이기 위해 노인에 대한 치위생교육이 필요하고 노인에 대한 지식뿐만 아니라 태도에 대한 교육도 실시되어야 한다. 4. 동일한 치과를 계속적으로 다니는 이유는 첫 번째 의사의 높은 진료수준, 두 번째 친절도로 의사요인과 관련이 가장 높은 것으로 나타났다. 또한 3-4년 이상의 장기내원환자는 의사의 높은 진료수준 다음으로 친절도를 중요한 이유로 선택하였다. Conclusions : 이상의 결과로 노인 환자가 만족하는 치과는 치과의사와 치과위생사의 진료수준이 높아야 하겠고, 다음으로 친절한 서비스가 중요함을 알 수 있었다. 또한 노인환자들의 만족도를 높이기 위해 노인에 대한 치위생교육이 필요하고 노인에 대한 지식뿐만 아니라 태도에 대한 교육도 실시되어야 한다.

The purpose of this study was to delve into how to provide better and more oral health education to middle school students, and to boost school oral health projects. The subjects in this study were 430 middle schoolers. After their oral health awareness, knowledge and oral health care were investigated, the following findings were given: 1. Concerning concern for oral health, 56.7 percent were oral health conscious, and as many as 43.2 percent were little or never concerned about it. 2. As to subjective oral health status, 36.7 percent found their own oral health status to be good, and 63.3 percent had a periodontal disease or felt that there was something wrong with their oral health. Regarding self-assessed abnormal oral symptoms, 25.8 percent considered themselves to have an abnormal symptom related to temporomandibular joint, and approximately 30 percent thought there was something wrong with their gums. 3. As for toothbrushing habits, the number of the girls who brushed their teeth after lunch was statistically significantly far larger than that of the boys who did. There were some differences between the boys and girls in toothbrushing method and in which part of the oral cavity they brushed. 4. In regard to oral health knowledge, the girls(a mean of 7.05) significantly excelled the boys(6.36). Those who were more oral health conscious got significantly better scores in oral health knowledge. 5. In terms of dental-clinic visit experiences, the students who had ever visited a dental clinic took in less sugar and got a more frequent regular dental checkup(2.62, 2.50) than the others who hadn't(2.32, 1.74).

The purpose of this work is to gain a better understanding of the interrelationships between geological structures and slope failure in sedimentary rocks. In the studied slopes, construction-related slope failure could only be observed on the south-dipping slopes. This indicates that slope stability may be dependent on the angular relationships between the dip direction of bedding and the orientation of the slope. Slope failure continued, post-construction, around large fault zones in the studied outcrop; these fault damage zones are, however, not easily recognized in the field. Here we suggest a new method that uses accumulated fracture density to precisely identify fault damage zones. Multiple-faced slopes are now increasingly being exposed during large-scale construction projects in South Korea. This multiple-faced slope analysis indicates that the stability of a slope should be evaluated by identifying domains, through the analysis of possible slopes and their angular relationships with bedding and other discontinuities, prior to construction. Therefore, careful consideration of geological structures such as bedding and other discontinuities, and their angular relationships during the design of cuttings through sedimentary rocks, will increase the efficiency of construction and enable the safe construction of more stable slopes that will retain their stability after construction.

The lexical semantic system should be built to grasp lexical semantic information more clearly. In this paper, we studied a semantic clustering of predicates that is one of the steps in building the lexical semantic system. Unlike previous studies that used argument of subcategorization(subject and object), selectional restrictions and interaction information of adverb, we used sense tagged definition in dictionary for the semantic clustering of predicate, and also attempted hierarchical clustering of predicate using the relationship between the generic concept and the specific concept. Most of the predicates in the dictionary were used for clustering. Total of 106,501 predicates(85,754 verbs, 20,747 adjectives) were used for the test. We got results of clustering which is 2,748 clusters of predicate and 130 recursive definition clusters and 261 sub-clusters. The maximum depth of cluster was 16 depth. We compared results of clustering with the Sejong semantic classes for evaluation. The results showed 70.14% of the cohesion.

This study has been conducted from July 30, 2007 to February 24, 2008 on 677 patients who were receiving diabetic treatment at the Health Centers of Deajeon City to find out their blood sugar level adjustment and their treatment compliance. As a result, 58.5% of them showed less than 200mg/dl of blood sugar level, and 67.9% showed their HbA1C of less than 7%, meaning that many of diabetic patients did not have their blood sugar level properly adjusted. And their after-meal blood sugar level and HbA1C adjustment varied depending upon the Health Centers. 88.0% of them were taking medicines for diabetic treatment regularly, and many of them were recognizing the need of dietary and exercise therapies to treat their diabetes. In conclusion, patients were recognizing that regular intakes of medicines, dietary and exercise therapies were very helpful to treatment of diabetes, but their treatments of HbA1C and blood level adjustment were not properly done as shown by their after-meal blood sugar level. The results were greatly different between the Health Centers, so there is a great need to cope with this situation.

In this study, we prepared elastic liposome containing rutin, known as antioxidants, and evaluated the physical characterization and enhanced skin permeation effect. The elastic liposome was prepared using the different ratios of egg phospholipids and $Tego^{(R)}$ care 450. The mean diameter of rutin loaded elastic liposomes formulations ranged between 205.7 ~ 298.0 nm and deforability 20.9 ~ 42.5, The loading efficiency was observed to be 52.0 ~ 71.0 %. The highest loading efficiency (71.0 %) and deformability (42.5) were observed at the optimal ratio of 85 : 15 (egg phospholipids : $Tego^{(R)}$ care 450) in the 0.1 % rutin loaded elastic liposome formulations. The elastic liposome formulation was selected for further transdermal permeation study. The elastic liposome(129.9 ${\mu}g/cm^2$) exhibited a significantly higher skin permeation compared with general liposome (98.0 ${\mu}g/cm^2$) and 1,3-butylene glycol (76.3 ${\mu}g/cm^2$) solution. These results suggest that the elastic liposome formulation using $Tego^{(R)}$ care 450 as a major edge activator could be useful for the delivery of active ingredient through the skin barrier.

The effects of mycelium of Cordyceps militaris on the growth, the lipid metabolism, the serum protein levels and the enzyme activities in male rats were studied. Sprague-Dawley rats were given four different types of diets for a succeeding period of five weeks: either a control diet, a control diet supplemented with 2%, 3% or 4% mycelium of Cordyceps militaris (CM) powder. The body weight gain, hepatic weight, feed efficiency ratio and the feed intake of the rats given diets with 2%, 3% or 4% CM were similar to those in rats given the control diet. The concentrations of hepatic total lipid and triglyceride of rats fed the 3% or 4% CM diets were significantly lower than those of rats fed the control diet. But the concentrations of hepatic total cholesterol and phospholipid of rats fed the all CM diets were similar to those of rats fed the control diet. The concentrations of total lipid, total cholesterol, triglyceride phospholipid, and the atherogenic index, and the activities of glutamic oxaloacetic transaminase and lactic dehydrogenase in serum of rats fed the all CM diets were significantly lower than those of rats fed the control diet. No differences were noted in the concentrations of HDL-cholesterol, LDL-cholesterol, total protein, albumin and creatinine, and the activities of glutamic pyruvic transaminase, ${\gamma}$ -glutamyltranspeptidase and alkaline phosphatase in the serum among the rats with on all the experimental diets. These results showed that the all CM diets feeding decreased the total cholesterol, the triglyceride, the phopholipid, and the atherogenic index in serum of rats.

SNS is in the process of fast evolution as well. This study is about influence of authenticity and interactivity among Facebook Fan Page users. Authenticity is something people form in the process of expressing and sharing information thru SNS Facebook Fan Page. Interactivity is a level of participation of users in the process of expressing and sharing information thru SNS Facebook Fan Page. The focus of this paper is to see the power of authenticity and interactivity of SNS Facebook Fan Page users in a time of crisis. Authenticity is proven as a valuable asset for corporations for it showed a sturdy characteristic even when something terrible happened. When a crisis attacked, high authenticity user group was not willing to change their evaluation on a company reputation and image as much as low authenticity user group. Interestingly enough, the meaning interactivity level was strikingly different from what we expected. The more their level of interactivity, was the more they were likely to change their evaluation on a company in a time of crisis. A serious discussion is necessary for this contraty results.

In Korea, a variety of policies for the regional cultural industry development have been carried out: the promotion policy of cultural industry cluster, the establishment of cultural industry support center, and the construction of cultural industry complex and the supporting works for the cultural research center. The cultural industry has a dual character of the manufacturing industry and the service industry. The cultural industry of Gyeongbuk province is mostly centered upon small manufacturing firms with low value-added. Thus, it is desperately in need of the building-up of the enterprise supporting system. However, it is difficult to expect that private business service finns can be activated. In this sense, local and regional governments seek to establish so called 'the cultural contents support center'. However, it is not clear whether the center is an organization for the production of cultural contents or an agency for the support of cultural contents industry. Also it does not prepare any major functional introduction facilities and performing programs. Most of all, it is necessary to establish a proper orientation that 'the cultural contents support center' must be not an organization for the direct production of cultural contents, but an organization supporting cultural industry by way of providing cultural industry enterprises with what is necessary for the production of cultural contents. Also, a system for the establishment of business fitting support policy that can cover the whole sectors of cultural industry must be prepared. Furthermore, a synthetic support system for the cultural business associated industries centered on specified sectors such as films, edutainment, and storytelling must be constructed. Finally an environment for the creation and inducement of cultural industry enterprises, and for the active participation of enterprises and related groups in the promotion planning and in the policies of cultural industry must be built along with on- and off-line networks.

Heavy drinking disrupts the nervous system by activation of GABA receptors and inhibition of glutamate receptors, thereby preventing short-term memory formation. Degradation of cognition by alcohol induces blackouts, and it can lead to alcoholic dementia if repeated. Therefore, drugs need to be developed to prevent alcohol-induced blackout. In this study, we confirmed the effect of an ethanol extract of Cassia obtusifolia seeds (COE) on alcohol-induced memory impairment. The effects of COE and ethanol on cognitive functions mice were examined using the passive avoidance and Y-maze tests. The manner in which alcohol affects long-term potentiation (LTP) in relation to the learning and memory was confirmed by electrophysiology performed on mouse hippocampal slices. We also measured N-methyl-D-aspartate (NMDA) receptor-mediated field excitatory synapses (fEPSPs), which have a known association with cognitive impairment caused by ethanol. Ethanol caused memory impairments in passive avoidance and Y-maze tests. COE prevented these ethanol-induced memory impairments in these tests. Ethanol also blocked LTP induction in the mouse hippocampus, and COE prevented this ethanol-induced LTP deficit. Ethanol decreased NMDA receptor-mediated fEPSPs in the mouse hippocampus, and this decrease was prevented by COE. These results suggest that COE might be useful in preventing alcohol-induced neurological dysfunctions, including blackouts.
