Oral health is a critical factor for diagnosing overall health, as poor oral health has a negative impact on food intake and results in deterioration of nutritional status. The purpose of this study was to research the needs for food developments for the elderly based on their oral and overall health status. Oral status was significantly associated with self-reported health status, and dry mouth (lack of saliva) especially showed a significant relationship with negative self-perception of both oral and overall health. For both elderly men and women, fish and leafy vegetables were the most preferred side dishes. Bread, rice cake, and beverage-type foods were also preferred for snack development. Disease status of the elderly was significantly related with their preference for food development. For instance, those with diabetes were more likely to ask for anti-diabetic diets. The most important factor for the elderly in choosing food was nutritional balance, and less than 3,000 won was cited as an affordable price. The results could be utilized as basic data to develop foods for the elderly.

Objectives : The purpose of this study was to determine the effects of oral health on the quality of life of elderly patients with dentures or implants. It is our intention that through this analysis we can aid seniors in making the choice between dentures or implants, considering future masticatory function and the likely effects of this decision on the patients quality of life. Methods : This survey was conducted between November 1, 2010 and November 25, 2010, in Kyunggi-Do, whasung city. The research was carried out at one public health center, among elderly patients. 105 seniors were surveyed using the direct interviewing method, oral health related quality of life was measured by the Philadelphia Geriatric Center(PGC) Morale Scale. Collected data was examined using the SPSS 13.0 program, using frequency, mean, and standard deviation analysis, T-test and $x^2$ test. Results : The number of residual teeth for patients who have implants was $20.45{\pm}5.85$, while among those patients with dentures the number was considerably lower, $8.11{\pm}7.66$(p<0.05). The results of patients masticatory function, was $28.13{\pm}2.40$ for those with implants, and $25.35{\pm}4.15$ with dentures. The results were better for those with implants. Among implant patients overall satisfaction was rated $25.21{\pm}3.63$, higher than for those with dentures $20.20{\pm}6.79$(p<0.05). Quality of life was scored higher for patients with implants($12.76{\pm}2.61$) compared to those with dentures($10.47{\pm}3.52$)(p<0.05). The subjects masticatory function was highly related to the number of remaining teeth and greater masticatory function had a positive effect on patients quality of life and life satisfaction. Conclusion : Dental treatments such as dentures and implants will have a great influence on patients quality of life and life satisfaction. Implants can improve the oral health related quality of life and satisfaction and the general quality of life more than denture therapy.

This paper aims to identify the relationship between the number of teeth of the elderly and their life happiness index. A face-to-face interview survey was conducted with elderly residents of Dong-gu, Daejeon from June 27 to July 25, 2012. A Tukey post hoc test and correlation analysis were implemented after a t-test and variance analysis. The results of analysis showed that satisfaction with life related to oral health was significant, but happiness in daily life had no significant difference. For the elderly, the quality of life related to oral health and happiness in daily life had no significant difference. Masticatory performance difference depending on usage of dentures also showed significant difference (p<0.001). The difference of masticatory performance depending on the number of teeth was analyzed by a correlation analysis. The present number of teeth, present anterior teeth and molars demonstrated a correlation. Quality in life related to oral health depending on the number of teeth correlated with the present number of teeth, present anterior teeth and present molars.

디지털 콘텐츠를 제작하려면 우선 창작되어야 한다. 창작은 팀을 이루어 공동으로 진행되기도 하며, 개인 창작에 의해 저작되기도 한다. 창작물은 글, 그림, 음악 등으로 표현되며 디지털 기기에 의해 창작된다. 이어서 콘텐츠 제작기술을 활용해 디지털 콘텐츠를 만든다. 지극히 당연한 이야기이지만 디지털 콘텐츠를 만드는 것은 제작기술이 아니라 사람이다. 콘텐츠 제작 스텝들이 자율적이고, 힘이 넘치고, 능력이 있다고 하더라도 기술과 팀워크가 뒷받침해주지 못한다면 역시 작품은 신통치 못할 것이다. 디지털 콘텐츠 제작을 위해서는 우선 목적하는 디지털 콘텐츠를 설계하고, 설계에 의해 컨셉과 시나리오를 작성하며, 제작팀을 조직해 디지털 소재의 가공과 편집이라는 과정을 거쳐야 완성된다. 콘텐츠 제작과정에서는 작업의 관리와 사람(제작 스텝)의 리드가 필요하다.

In implementing a computerized virtual training system, the auditory element is responsible for the human cognitive ability following visual elements. Especially, the improvement of hearing ability is closely related to the performance of the training, and it contributes to improvement of the training effect. In this paper, we propose a sound system that is necessary for constructing such a virtual training system as a test system that can use a sound source using a head related transfer function (HRTF). Functional and auditory tests were performed to evaluate system performance.
