The objective of this paper is to study on the property transformation for materials and to evaluate the precision through marginal gap depending on heat-treatment of metal-porcelain by the gold electro-forming system. Specimens for evaluating property of hardness treat non-treat(HC), once(H1), twice(H2), and three times(H3) by heating, respectively. Specimens for marginal gap classified as each groups of special bonder(FS), special bonder, opaque(FO), special bonder, opaque, body(FB) and non-treatment(FC). As a result for micro-hardness test, the level of hardness on each groups of H1, H2, H3 decreased rather than HC group(p<0.05). In addition, marginal gap was not affected by the number of times being treated by heating. Therefore, the marginal fitness and the precision for mterials were not affected by the heat-treatment on the process to make GES metal-porcelain.

This study was conducted to investigate the oral health perception according to the actual condition of oral hygiene products management in 222 college students in Daegu and Kyungbuk province (p<0.05). The subjects in the study were 43 men (19.4%) and 50 women (22.5%) with two toothbrushes (p<0.05), and the major subjects were 2 tooth brushes The subjects were 18 (8.1%) and 75 subjects (33.8%) were subjects of science major (p<0.001). Among the subjects who did not carry a toothbrush, 72(32.4%) were male and 46 (20.7%) were female. The number of subjects who did not carry the male was higher (p<0.05) The subjects were as follows: 83 (37.4%), and 21. Oral health awareness was 3.031 times higher than that of male (p<0.001), and the major group was 2.57 times higher than that of the general population (p<0.001). Subjects who did not sterilize the toothbrush had 0.459 times lower oral health perception (p<0.05). In order to establish and evaluate the oral health policy of university students in Korea, only the objective oral health status is used as an index. However, it is necessary to study and reflect the variables affecting oral health awareness as much as the oral health awareness reflects not only oral health condition but also socioeconomic variables and the effect of variables on oral health.

This study attempts to comprehensively evaluate differences in sociodemographic characteristics, health behavior, disease morbidity, medical care and health-related quality of life of medical aid beneficiaries and health insurance beneficiaries. To achieve this, this study analyzes primitive data of community health survey that each health center had recently conducted in 2013. Study socioeconomic characteristics, health behavior, disease morbidity, medical care showed that various factors affecting health-related quality of life. It was found that medical aid beneficiaries showed lower health related-quality of life than health insurance beneficiaries because not good socioeconomic characteristics, health behavior, disease morbidity, and medical care and even as a comparative result after controlling socioeconomic characteristics, it was found that medical aid beneficiaries health-related quality of life was lower because of not good health behavior, disease morbidity, and medical care. Therefore, to improve health-related quality of life in medical aid beneficiaries as effectively as possible, improving mental health including managing chronic disease and stress and depression and daily living activities is above all important and our national concern with developing systematic program and policies focusing on health promotion behaviors such as moderate drinking habits and regular exercise and eating habits is required.

In this study, we analyze the community health survey data for 3 years from 2011 to 2013 were analyzed for evaluation. This study attempts to comprehensively evaluate differences between elderly medical aid beneficiaries and elderly health insurance beneficiaries in terms of health-related quality of life, All of elderly medical aid beneficiaries who responded community health survey were included for study and elderly health insurance beneficiaries were randomly selected as a control group by matching gender, age and location. The findings show that the elderly medical aid beneficiaries can not receive sufficient health care services, even though they have pay a low socio-economic status, spouse or fewer households enemies and poorer health behavior and higher morbidity of chronic diseases than the elderly health insurance beneficiaries do. But elderly health insurance beneficiaries also showed that not enough care utilization is high morbidity of chronic diseases. These factors aggravate the medical aid beneficiaries' health-related quality of life This characteristic was analyzed to lower health-related quality of life of the elderly. Therefore, it is necessary to strive for the development of appropriate services and programs taking into account the characteristics of the elderly that may go though a limited resource and promote the quality of life for the elderly more effectively re-evaluation of social services systems and programs related to elderly.

Distinguishing aphasia in stroke patients and observing the subtle linguistic characteristics associated with it primarily requires the use of instruments that provide reliable assessment results. Additionally, examiners should be fully aware of how to use those instruments. This study examined 46 stroke patients for aphasia and assessed the reliability of their diagnoses according to examiners whose medical fields were different from each other. Furthermore, a comparison was made between the reliability before training and that after training. To this end, 46 stroke patients were tested for aphasia and in terms of their speech disorder degree by 3 groups, each of which consisted of 12 professionals (3 SLP, 3 neurologist, and 3 nurse). In the result, a rating of 'acceptable' was given for speech intelligibility tasks and the voice quality of /ah-/ prolongation, and other sub-tests were marked as 'good-excellent' by the experts with different areas of medical expertise. For the tasks marked as 'acceptable', the subjects were video-trained for 3 weeks and the differences were compared before and after their training. Consequently, the differences in the examiners' ratings in the speech intelligibility tasks showed a significant decrease and the accuracy of their voice quality ratings showed a significant increase. In the result of research on the correlation between the accuracy of the sub-test ratings and the amount of clinic experience, speech therapists developed more accuracy in rating a picture description task and a speech intelligibility task as their experience accumulated. Meanwhile, doctors and nurses showed more accurate ratings in picture description tasks with greater clinical experience. The results of this study suggest that assessing the neurologic-communicative disorders of stroke patients requires ongoing training and experience, especially for speech disorders. It was also found that the rating reliability in this case could be improved by training.

In order to achieve the low complexity and area, power in the design of Optical Image Stabilization (OIS) suitable for the smart phone, this paper presents the following design explorations, such as; optimization of gyroscope sampling rate, simple and accurate gyroscope filters, and reduced operating frequency of motion compensation, optimized bit width in ADC and DAC, evaluation of noise effects due to PWM driving. In experiments of gyroscope sampling frequencies, it is found that error values are unvaried in the frequency above 5KHz. The gyroscope filter is efficiently designed by combining the Fuzzy algorithm, to illustrate the reasonable compensation for the angle and phase errors. Further, in the PWM design, the power consumption of 2MHz driving is shown to decrease up to 50% with respect to the linear driving, and the imaging noises are reduced in the driving frequency above 2MHz driving frequency. The operating frequency could be reduced to 5KHz in controller and 10KHz in driver, respectively, in the motion compensation. For ADC and DAC, the optimized exploration experiments verify the minimum bit width of 11bits in ADC as well as 10bits in DAC without the performance degradation.

The establishment of Culture Technology Institute is now under discussion. In case of advanced countries (including USA, Japan and EU) practices market-oriented policies in the area of culture and entertainment industry. Therefore it is hard to find out Government-funded Institute which Korea could benchmark. In this situation, there are many different opinions about its organizational structure, size of organization and budget, and when the institute should be established. This study proposed a Consolidated-Decentralized model as a proper organizational structure after evaluating 4 different models based on 4 criterion. And based on results produced by the model developed for our research, this study suggested proposals that the number of research personnel and the size of budget should be larger than 300 persons and 1200 billion won respectively. However, the establishment of institute should be decided by not only economic factor but also various factors such as political element, externality, private company investment and effect on production inducement etc. If new institute focused on different area from ETRI, then the time and size of the institute could be decided by the result of policy analysis.

In this study, we have examined how the potential users of IT convergence product use the external information sources for purchasing decision focusing on a case of smartphone. Although the specifications and price of IT convergence products, such as smartphone, tablet pc, and smart TV, are considered as major criteria for purchasing decision, the competitiveness of these factors have disappeared as many companies launch similar products in the market. External information sources play a significant role to differentiate the alternatives by offering value-added experience information. The effect of external information sources becomes stronger for experience and high-involvement product whose performance can be evaluated through only users' direct experience. In this study, we categorized the external information sources for smartphone into five; company ads, personal network, expert group, consumers, and media. Through an empirical study with potential smartphone users, we verified how these external information sources affect users' purchasing decision in the perspective of the perceived attributes of information source, quality of information, and individual's characteristics based on self-regulatory theory.
