Purpose: In order to validate empirically the theoretical model of this study subjects, who were limited in Andong gun, Youngyang gun, Uiseong gun, Bonghwa gun, Chilgok gun, Cheongsong gun according to residence-specified distribution and over aged 65, were focused to the elderly in rural areas with geographical characteristics where they have difficulties in accessibility of dental facilities and dental care. Methods: The collected data were analyzed by the SPSS 19.0 program. First, the frequency analysis was performed for each independent variable and the dependent variable. Second, reliability analysis and correlation analysis were conducted for daily living skills and Biomedical Vigilance. Third, multivariate analysis was performed in terms of and the post-administration management. Fourth, multiple regression analysis was performed to identify the factors affecting the post-management of dentures and the period of using dentures. Results: By results of the multiple regression analysis, the elder the subjects are(${\beta}$ = 0.03), the lower their income activities are(${\beta}$ = -0.18), the smaller their monthly allowances are(${\beta}$ = -0.16), the worse their daily activity skills are(${\beta}$ = -0.12), the more they were mounted their dentures by an unlicensed contractor(${\beta}$ = 0.07), and the more they cost to their dentures(${\beta}$ = 0.14), the longer the period of use dentures are. And the beneficiaries of Basic Livelihood Security(${\beta}$ = -0.14) who got free denture business are shorten the period of using dentures. According to multiple regression analysis for post management of dentures, the independent variables like the health education(${\beta}$ = 0.24), smoking(${\beta}$ = -0.18), periodic oral examination(${\beta}$ = 0.13), dentures mounted by an unlicensed contractor(${\beta}$ = -0.13) are shown statistically significant results. In that study subjects are taking part in health education and non-smokers, they are likely to have more chances to post management for their dentures like periodic oral examination. However the subjects who were weared their denture by an unlicensed contractor get less chance to post management for their dentures. Conclusion: As the elderly who want to wear denture are increasing due to the denture insurance for the elderly, the need for oral health education for the elderly is an urgent request, especially continuos education for the way of use their dentures and follow-up management for the elderly who were already mounted their dentures. And also, the need for more systematic researches is requested for securing objective data.

We aimed to characterize the participation of rapid non-genomic and delayed non-genomic/genomic or genomic mechanisms in vasoactive effects to triiodothyronine (T3), emphasizing functional analysis of the involvement of these mechanisms in the genesis of nitric oxide (NO) of endothelial or muscular origin. Influences of in vitro and in vivo T3 treatments on contractile and relaxant responsiveness of isolated rat aortas were studied. In vivo T3-treatment was 500 ㎍·kg-1·d-1, subcutaneous injection, for 1 (T31d) and 3 (T33d) days. In experiments with endothelium-intact aortic rings contracted with phenylephrine, increasing concentrations of T3 did not alter contractility. Likewise, in vitro T3 did not modify relaxant responses induced by acetylcholine or sodium nitroprusside (SNP) nor contractile responses elicited by phenylephrine or angiotensin II in endothelium-intact aortas. Concentration-response curves (CRCs) to acetylcholine and SNP in endothelium-intact aortic rings from T31d and T33d rats were unmodified. T33d, but not T31d, treatment diminished CRCs to phenylephrine in endothelium-intact aortic rings. CRCs to phenylephrine remained significantly depressed in both endothelium-denuded and endothelium-intact, nitric oxide synthase inhibitor-treated, aortas of T33d rats. In endothelium-denuded aortas of T33d rats, CRCs to angiotensin II, and high K+ contractures, were decreased. Thus, in vitro T3 neither modified phenylephrine-induced active tonus nor CRCs to relaxant and contractile agonists in endothelium-intact aortas, discarding rapid non-genomic actions of this hormone in smooth muscle and endothelial cells. Otherwise, T33d-treatment inhibited aortic smooth muscle capacity to contract, but not to relax, in an endothelium- and NO-independent manner. This effect may be mediated by delayed non-genomic/genomic or genomic mechanisms.
Numerous clay veins along fractures such as fault, joints, cracks and small fissures are found in granitic rocks in the Korean Peninsula. Granitic rocks of three geological stages (Jurassic, Cretaceous and Paleogene) occur in the Korean Peninsula, and are known as the Daebo, Bulguksa and Hoam granites, respectively. Specimens from clay veins composed or mainly mica clay mineral (illite) were dated using the K-Ar method with the hosted granitoids. The respective ages were as follows. Jurassic: granites 143.7 Ma and 160 Ma, clay mineral veins 104 Ma and 107 Ma: Cretaceous: granite 133.2 Ma, clay mineral veins 93.6 Ma, 84.2 Ma and 84.3 Ma: Paleogene: granite 39.7 Ma and 35.4Ma, clay mineral veins 27.1 Ma and 23.9 Ma. The ages of the clay veins in the Korean Peninsula are clearly much younger than those of their hosted granitoids. This contrasts with data for similar clay veins in Cretaceous and Paleogene granitoids in southwest Japan, where the K-Ar ages of mica clay minerals are slightly younger than their host rocks, or are almost the same.
Since Radix Stemonae was recorded hypothennal and a little toxic in the 'Myngyubelrok (名醫別錄)', it has been recorded as having the same nature in many herbal books. However, the security of Radix Stemonae when used to treat respiratory disease over a long term has not been studied until now. Therefore, the objective of this study is to determine the effects of Radix Stemonae on the main organs if Radix Stemonae is administrated over a long term. In order to investigate the histological changes of the liver and kidneys of rats after oral administration of Radix Stemonae extract, the experimental rats were subdivided into control, 1, 3, 5, 7, 21, 28 and 35 days after administration groups, and 10 rats per group were used in this study. The control group was sufficiently supplied with water and solid forage. The other groups were administrated the reagent at 5mg/kg once a day by oral injection. Several times each day, the experimental groups were carefully observed for any changes of general condition, toxic symptoms, activity, appearance and the number of dead rats. The experimental groups were weighed and narcotized. For the histological observation, the tissues of liver and kidneys of the experimental groups were collected, stained by hematoxylin-eosin stain, and evaluated by observing the changes of gross appearance and by observing microscopic findings. 1. This drug, during the experimental term, did not induce any toxicological effect in mortality, abnormal symptoms or changes of body weight except for the 1 day after administration groups whose body weights were decreased, compared to the control group. 2. No gross changes of the liver and kidneys were observed in this study. 3. No histological changes of the liver were detected in 1 day after administration groups. However, dilation of the central vein was observed in 3, 5 and 7 days after administration groups and chronic passive congestion of the liver was demonstrated in the 21 days after administration groups. In the 28 and 35 days after administration groups, a centrolobular disposition of fatty tissue (adipose cell) was observed. 4. No histological changes of the kidneys were observed in this study. It is evaluated that if Radix Stemonae is administrated for a long term, it induces toxicity in the liver. So, to examine the toxicity of Radix Stemonae on the liver and kidney, it is necessary that the studies of biochemistry and electron microscopic findings about Radix Stemonae be systematically performed.

Fire incidents, which occur every year, cause huge damage to properties and humans. Significant time and costs have been invested in minimizing and responding to such accidents. With the recent advances in the development of spatial information, in the firefighting field, studies have been conducted to effectively bring fires under control using GIS(Geographic Information System). Most of such studies, however, focused on individual analyses of firefighting-related factors, but comprehensive research on the vulnerability factors in fire control activities, a major part of firefighting activity, has yet to be done. This study sought to pinpoint and analyze the factors that obstruct fire controlling, and to gather relevant data and create GIS-based databases. Based on such database, GIS-based overlay analysis was conducted to produce a fire control vulnerability map. The findings of this study will enable a quantitative analysis of firefighting obstruction factors to assist the personnel engaging in firefighting in rational decision-making, such as in formulating a firefighting operation plan for securing golden time.

Looking at the application examples related to RFID systems around the world, it is easy to find that RFID systems are introduced in various industries, such as retail and consumer goods sectors, financial and security sectors, automotive and transport sector, leisure and sports sector, logistics, and health-related fields. This is because they can get their operational efficiency and competitiveness by means of product's visibility and transparency of information through RFID systems. However, it is required that evaluation of effectiveness on introducing RFID systems should be performed to strengthen construction willingness of RFID systems before actual introduction of the RFID systems in the process. This activity affects to introduction of RFID systems in industry-wide and then, will be able to create a synergy effect such as national industrial competitiveness improvement. The purpose of this study is to offer rational method on effectiveness analysis before and after RFID based process. Accordingly, the proposed Choquet fuzzy integral-based model will be allowed rational analysis by integrating quantitative and qualitative analysis. Through the effectiveness analysis of C company's RFID based process using the proposed evaluation model, we could identify that RFID-based logistics process was more effective than existing process.

The smartphone is the communication device that is the most personal to the user, and it keeps a lot of information related to the user and makes information communication with other devices. With these characteristics, forensics on smartphones are one of the most basic methods of investigation in criminal investigations, and have actually contributed to the settlement of the case by providing many clues. However, recently, it is designed to encrypt data stored as a social issue related to the protection of user's personal information, or to delete deleted data or to delete log data together. So, any solutions? In this paper, I try to find the answer from cloud data stored by smartphone user account. Cloud forensics should approach complementary relationships rather than smartphone forensics. There are a lot of data stored in the cloud that can be meaningfully used in the investigation. Online activity information of users, such as Internet usage, YouTube view, and contents purchase information, cloud service such as e-mail, cloud drive, and location information are the most representative data. These data can be unvaluable, but here are some important clues in various types of criminal investigations. In this paper, I propose a method to extract data from the google cloud so that the data can be used for investigation, and to utilize the extracted data for investigation. And it explains the role of the extracted artifacts in the actual investigation business through virtual cases and proves its value.
The purpose of this study is to understand the current state of the older people's social exclusion by identifying patterns of the change in social exclusion level through a longitudinal analysis with an aim of exploring the predictors of changes. To this end, this study has adopted the panel data, the English longitudinal Study of Ageing(ELSA). The data of 7631 respondents who aged over 50 were used for the final analysis. The social exclusion of the older people was analyzed into five different sub-dimensions: social relationship; cultural activities; access to health services; financial security; and sense of loneliness. The person-centered approach that focuses on the various patterns of the trajectories of change has used semi-parametric group based model in order to estimate different trajectories among individuals. The data was analyzed using Spss 18.0 and SAS 9.2 proc traj. In results, First, semi-parametric group-based model analysis has shown that the older people are not 'homogeneous' group with similar exclusion level in every individual with same trajectories of change, but can be divided into various categories with diverse intercept and slope. Second, different trajectories in change of exclusion level help to confirm that the older people's social exclusion level increases gradually over time or remains unchanged. Third, this analysis has provided the useful guidelines to identify the high-risk groups of social exclusion. Forth, the variables that make difference in more than three dimensions include gender, age, self-perceived health, physical activity, weekly income, marital status, family relation, and beneficiary status. Implications and further suggestion were discussed.
In this study, we analyzed knowledge management cases of the Ministry of Culture, Sports and Tourism and examined knowledge management vision, promotion organization and knowledge management activity system. This study aims to clarify implications for successful knowledge management in government sector. In the case of the Ministry of Culture, Sports and Tourism, which was the subject of the study, it was evaluated as having performed well in the management activities of the government department in the evaluation of "Knowledge Target for 2018" jointly hosted by Maeil Economic Daily and the Ministry of Public Administration and Security. In this study, we conducted an in - depth interview with the knowledge management staff of the Ministry of Culture and Tourism and analyzed the success factors of knowledge management in the government sector. First, the vision of knowledge management and the role of dedicated organization were very important. In addition, knowledge management system was used to effectively acquire, share, and accumulate knowledge and utilize it. In addition, appropriate compensation systems for knowledge management activities are also important success factors. Therefore, in order to encourage knowledge management activities, it is necessary for public institutions to establish an incentive system such as an economic compensation system for personnel sharing activities and HR personnel.
