According to the result of examining the recognition on subjective oral health knowledge and elderly oral health management with a self-administered questionnaire survey conducted to 233 workers of elderly care facilities located in Gyeonggi-do, it was shown that their general oral health knowledge level was high while their elderly oral health knowledge was lower than general oral health knowledge. And it was found that respondents answering they had keen interest in the level of oral health knowledge according to the interest in elderly oral health showed a higher level of oral health knowledge than those answering they had no interest in it, which indicated statistically significant difference (p<.001). Regarding the study subjects' elderly oral health management and educational demand, quite a high percentage of 83,7% responded the education is needed. A response that it is appropriate for dental hygienists to give elderly oral health management and the education showed 57.9%, which was the most. Also, it was shown that in the level of oral health knowledge according to the recognition of elderly oral health managers and educators, subjects recognizing that it is needed to be dental hygienists indicated a high level of oral health knowledge, which showed statically significant difference (p<.05).

The objective of this study is to empirically examine the effect that social welfare officials' awareness of welfare, who play the core role in delivering public welfare service, has on their sense of duty value and duty efficiency. The implications this study suggests are as follows; First, this study has a meaning in that it empirically proved the social welfare officials' awareness level of welfare. Second, this study provided the specific theoretical basis for the approaches and alternatives for the need to improve social welfare officials' awareness of welfare and operate the desirable welfare policy and system, by examining the effect that social welfare officials' awareness of welfare has on their sense of duty value and duty efficiency. Third, we can find the political implication from this study that welfare policy should be established and operated toward the direction of enhancing equalization effect of welfare system, and minimizing free ride or hampering the will to work, if we intend to improve social welfare officials' awareness of welfare. Fourth, this study presented the need to improve the work system of social welfare officials, through the fact that the shorter their work period is, the lower sense of welfare, duty value and duty efficiency they have. Based on the study results above, we suggest the activation of studies on social welfare officials' awareness of welfare, the need to regularly educate social welfare officials about welfare policy, system and value, the need to improve social welfare officials' positive awareness of welfare and their duty performance through deciding welfare policy toward the direction of enhancing social equality and equalization, and the need to improve social welfare officials' work system.

A new online routing algerian is proposed in this paper, which use the interference-prediction to solve the network congestion originated from extension of Internet scope and increasing amount of traffic. The end-to-end QoS has to be guaranteed in order to satisfy service level agreements (SLAs) in the integrated networks of next generation. For this purpose, bandwidth is allocated dynamically and effectively, moreover the path selection algorithm is required while considering the network performance. The proposed algorithm predicts the level of how much the amount of current demand interferes the future potential traffic, and then minimizes it. The proposed algorithm considers the bandwidth on demand, link state, and the information about ingress-egress pairs to maximize the network performance and to prevent the waste of the limited resources. In addition, the interference-prediction supports the bandwidth guarantee in dynamic network to accept more requests. In the result, the proposed algorithm performs the effective admission control and QoS routing. In this paper, we analyze the required conditions of routing algorithms, the aspect of recent research, and the representative algorithms to propose the optimized path selection algorithm adequate to Internet franc engineering. Based on these results, we analyze the problems of existing algorithms and propose our algorithm. The simulation shows improved performance by comparing with other algorithms and analyzing them.

Career and academic Counseling is often viewed as the catalyst for frequent and consistent interaction with students, but it is more than simply advising students about which majors, universities or jobs to consider. Ongoing, personal contact of career and academic counselors with students is an essential component in long-term career-related efficacy. But statistics show that high schools in non-urban or rural areas face significant issues different from those schools in metropolitan or suburban contexts, failing to maintain the significant number of teachers enough for effective career and academic counseling. This article proposes an alternative model of career and academic counseling, provided by MBA(Master of Business Administration) alumni based social enterprise in Seoul. This service explores the skills, knowledge and capabilities which MBA alumni gained from their jobs and MBA programs within the context of a career-competency framework. This paper concludes with the social and educational aspect of this shared responsibility strategy that may enhance student motivation and persistence in non-urban high schools.

The study aimed at identifying the causes of the high level of health application but the low level of use. In other words, the effects of user's innovation resistance (use barrier, value barrier, risk barrier, traditional barrier, image barrier, etc.) were examined. For this study, 378 valid responses were collected by conducting surveys with college students. Findings indicated the higher the level of image barrier of the user, the higher the degree of innovation resistance for the health application, and the higher the degree of innovation resistance, the lower intention of continuous use and recommendation. In addition, the level of use barriers, value barriers and traditional barriers did not have a significant effect on the degree of innovation resistance, suggesting that users familiar with smartphones have low resistance to health applications. The study deepens the theoretical discussion about the adoption and continuous use of new technologies by explaining the use of health applications in the theory of innovation resistance. The findings of the study provide the practical implications that lowering the image barriers rather than the usage barriers, value barriers and traditional barriers will be effective for the adoption and continuous use of health applications.

The purpose of this study was to identify the trends and risk of bias of research using time series analysis on health and welfare in Korea and to suggest a direction for future health and welfare research. The database searches identified 6,543 papers. Following the process for screening and selecting, a total of 91 papers were included in the systematic review. There has been a steady increase in the number of articles using time series analysis from 1987 to 2013. Time series analysis was applied in medicine and health science journals. The main goals were explanation and description. Most of the subjects were heath status and utilization of healthcare services. The main model used in the time series analysis was ARIMA followed by time series regression. The data were gathered from various sources, including the national statistical office and government agencies. For assessing risk of bias, some studies were found to have inadequate sample sizes or showed no time series graphs and plots. These findings suggest greater widespread utilization of time series analysis in the field of health and welfare and to use the appropriate analysis methods and statistical procedures to obtain more reliable results to improve the quality of research.

The most important issue in providing multimedia traffic on a mobile computing environments is to guarantee the mobile host(client) with consistent QoS(Quality of Service). However, the QoS negotiated between the client and network in one cell may not be honored due to client mobility, causing hand-offs between cells. In this paper, a call admission control mechanism is proposed to provide consistent QoS guarantees for multimedia traffics in a mobile computing environment. Each cell can reserve fractional bandwidths for hand-off calls to its adjacent cells. It is important to determine the right amount of reserved bandwidth for hand-off calls because the blocking probability of new calls may increase if the amount of reserved bandwidth is more than necessary. An adaptive bandwidth reservation based on an MPP(Mobility Pattern Profile) and a 2-tier cell structure has been proposed to determine the amount of bandwidth to be reserved in the cell and to control dynamically its amount based on its network condition. We also propose a call admission control based on this bandwidth reservation and "next-cell prediction" scheme using an MPP. In order to evaluate the performance of our call admission control mechanism, we measure the metrics such as the blocking probability of our call admission control mechanism, we measure the metrics such as the blocking probability of new calls, dropping probability of hand-off calls, and bandwidth utilization. The simulation results show that the performance of our mechanism is superior to that of the existing mechanisms such as NR-CAT1, FR-CAT1, and AR-CAT1.

Assesment of 30 nutritional minerals and 8 toxic elements in hair are very important not only for determining adequacy, deficiencies and unbalance, but also for assessing their relative relationships in the body. A test has been developed that serves this purpose exceedingly well. This test is known as tissue mineral analysis(TMA). TMA is very popular method in hair mineral analysis for health care professionals in over 46 countries' medical center. However, there are some problems. First, they do not have database which is suitable for korean to do analyze. Second, as the TMA results from TEI-USA is composed of english documents and graphic files prohibited to open, its usability is very low. Third, some of them has low level database which is related to TMA, so hairs are sent to TEI-USA for analyzing and medical services. it bring about an severe outflow of dollars. Finally, TMA results are based on the database of american health and mineral standards, it is possibly mislead korean mineral standards. The purposes of this research is to develope the first Intelligent Medical Expert System(IMES) of TMA, in Korea, which makes clear the problems mentioned earlier IMES can analyze the tissue mineral data with multiple stage decision tree classifier. It is also constructed with multiple fuzzy rule base and hence analyze the complex data from Korean database by fuzzy inference methods. Pilot test of this systems are increased of business efficiency and business satisfaction 86% and 92% respectively.

Most of Korea's 15 local airports, with the exception Jeju, Gimpo and Gimhae airports, have been several billion Won in the red each year. It has been reported that one of the causes of the poor financial performance is inaccurate air traffic demand predictions. Under the situation, the entry of low-cost carrier air service using turbo-prop airplanes into the domestic airlines market gets a wide range of support, which is expected to promote the convenience of consumers and help to activate local airports. In this study, the authors (1) suggest a high-speed transport demand model among existing airlines, Korea Train Express (KTX) and low-cost carrier air service; (2) try to make low-cost air carrier demand predictions for a route between Seoul and Daegu through a stated-preference survey; and (3), examine possible effectiveness of selected policy measures by establishing an estimation model. First, fare has a strong influence for mode choice between high-speed transport modes when considering the entry of low-cost carrier air service between Seoul and Daegu. Even low-cost carrier air service fare is set at 38,000 won, which is considerably low compared with that of KTX, in the regions where the total travel time is the same for both low-cost carrier air service and KTX, the probability of selecting low-cost carrier air service is 0.1, which shows little possibility of modal change between high speed transportation means. It is suggested that the fare of low-cost air service between Seoul and Daegu should be within the range of from of 38,000 to 44,000 Won; if it is higher, the demand is likely to be lower than expected.
