This survey was willing to suggest the basic data required for strategic planning to improve the recognition rate on radiation by investigating the difference between the college students who major in radiology and who don't about using radiation. As the results of questionnaire survey on 'knowledge, degree of self-consciousness, danger, convenience and management' targeting 441 students who belonged to D college, 75% of them answered that radiation exists in their daily lives and 54% of them answered they did not know about radiation well. It showed that radiation is dangerous no matter how much the amount is (56%) and it is not dangerous if it is managed well (81%). They answered that they enjoy the convenience of radiation (82%) and the use for medical purpose took the highest percentage among them (58%). It showed that it is important to manage the radiation and should be controlled by the government in institutional way than the individual (64%). The negative answer to the question of 'do you trust the government?' was dominant (75% below average). As the results of this survey, it was recognized that both of them who major in radiology or not were aware of positive aspect of radiation (especially medical technology field) well and the improving the perception of radiation led by the government and definite restriction on its safety should be preceded for safe use.

The Recommended Dietary Allowances(RDAs, Nutrient standards), dietary guidelines, and food guides, each define aspects for a healthy diet in different ways. The RDA and food guide for Koreans were first established in 1962 by the Food and Nutrition Committee of the Korea FAO Association. The committee released the RDA and suggested ways to intake the recommended nutrients. Every five years, the committee has added more data and released revisions. The latest edition of the RDA is the 6th revision. In the beginning, the concept of basic food groups was emphasized as basic data for planning means based on RDA. In the 5th revision, the basic food groups and dietary guideline for public health from the Ministry of Health and Welfairs(December, 1990) suggests that, 1) Eat a variety of foods with a recommended fat intake equaling or less than 20% of total calories ; 2) Maintain ideal body weight and prevent obesity ; 3) Eat foods low in salt. Salt intake should not exceed 10g ; 4) Do not drink too much ; 5) Eat regularly and enjoy meals. After these guidelines were established, the first nutritonal education efforts guidelines were developed in 1984. Despite broad possibilities for application, they had limited use, mainly as a nutritional assessment and food balance sheet preparation. They were not well utilized in public nutritional education and nutritonal policy through the media because of the weakness of the government's food and nutriton policy. Also a lack of administrative support and dietitians in the health department and administrative organizations was partly to blame. In regard to public health and nutrition status, life expectancy has increased 10 years since the 70's and the elderly population increased threefold in 1995 compared to 1960. The common causes of death in 1996 by 19 Chapters classification, were first disease of the circulatory system ; the second, neoplasms ; the third, external causes fo mortality ; the forth, diseases of the digestive system ; and the fifth, respiratory system diseases, In food intake, grain and complex starch intake has decreased while fruit and animal foods have considerably increased. Therefore, energy from carbohydrates has decreased while energy from protein and fat has increased. Energy intakes from protein, fat and carbohydrates were respectively 12.5, 7.2 and 80.3% in 1969 but 16.1, 19.1 and 64.8% in 1995. 62.9% of the householes had the fat energy less than 20%, while 37.1% had the fat energy above 20%. The only intakes of vitamin A and calcium were below RDA levles. Therefore, nationwide attention should be focused on public nutriton education and public activities with supplementation of the RDAs, according to the food guide and the dietary guideline.

The aging of population stems from the decline of birth and death rates. A sudden aging society results in a variety of social issues like the poverty, role loss, alienation, health problems, etc. of the elderly. What counts in solving these issue is to make good use of the leisure time of the elderly. Leisure activities in the elderly help maintain and improve their mental and physical health, and have a great influence on improving the quality of life in the elderly. In addition, they contribute to building up a healthy social structure by forming a social intimacy. Despite these positive aspects of leisure activities, however, multiple factors prevent the leisure activities of the elderly from being actively pursued. In this respect, since there is a need to take a look at how the varied leisure activities of the elderly expose themselves in different regions, this study made an investigation so as to see what characteristics and differences each region has in the leisure activities of the elderly 65 or above. As a result, the following facts were found out: the elderly in Seoul enjoy a relatively wide range of leisure activities compared with other regions; the elderly in Gwangju spend their time mainly at home: and the elderly in the Goheung region take part in leisure activities aimed at promoting friendship. It was also revealed that there are differences among different regions in the areas of leisure activities, including the types of participation in leisure activities, the types of leisure activities at and out of home, the purpose and satisfaction of leisure activities and the frequency of domestic trips.

If we look at Korea's urbanization since 1960, only the urban communities like buildings have developed, yet the resting places for human itself have been ignored. Many people continuously felt alienated especially after the mechanization and started to demand for better living space. For that reason, it is essential for us to develop the resting places for human among the buildings in urban areas and these resting places could form the basis of new community. We have researched on street furniture and citizen's behavior pattern in resting places through references and internet surfing to propose a design concept for a new resting place and street furniture, Therefore, we would like to design a resting place in urban area considering human, community and environment. As a result, we have designed a resting place where citizens could interact with surrounding environment and let office workers enjoy the nature among the buildings in this resting place. People could always stop by and take some rose by enjoying the surrounding nature. The resting place consists of 5 zones- public square, environmental zone, communication zone, technology zone, and entertainment zone. Each zone has its own design motif to lead systematic street furniture and site planning. The resting place is formed in a specific region which is a prototype of a resting environment in urban areas in the future and it could be reassigned according to its regional condition.

In oriental paintings, there is Luo-kuan that expressed in a single picture by compressing the artist's information. Such Luo-kuan includes various information such as the title of the work or the name of the artist. Therefore, information about Luo-kuan is considered important to those who collect or enjoy oriental paintings. However, most of the letters in the Luo-kuan are difficult kanji, kanzai, or various shapes, so it is difficult for the ordinary people to interpret. In this paper, we developed an Luo-kuan search application to easily check the information of the Luo-kuan. The application uses a search algorithm that analyzes the captured Luo-kuan image and sends it to the server to output information about the Luo-kuan candidates that are most similar to the Luo-kuan images taken from the database in the server. We also compared and analyzed the accuracy of the algorithm based on 170 Luo-kuan data in order to find out the ranking of the Luo-kuan that matched the Luo-kuan among the candidates. Accuracy Analysis Experimental Results The accuracy of the search algorithm of this application is confirmed to be about 90%, and it is anticipated that it will be possible to develop a platform to automatically analyze and search images in a big data environment by supplementing the optimizing algorithm and multi-threading algorithm.

The goal of this study is to examine what kind of repeated-reading habits adults have, what sort of books they read repeatedly, and what preferences they have depending on their age or gender. A questionnaire was distributed to the students at Lifelong Education Center of Chonbuk National University to survey their repeated reading experiences. The results of the statistical analysis are as follows: 1) Most adults have experienced repeated reading. 2) Women have more experience with repeated reading than men, and in terms of age, more people in their forties read the same books repeatedly. 3) Most repeated readers read their books twice: Women tend to read their books repeatedly more than men do. 4) More than half of the adults in the sample group have read their favorite books several times. 5) The importance of books in this study was judged on the basis of the number of repeated readers and the frequency of reading. The order of important books is as follows: The Little Prince, The Tale of Three Kingdoms, The Giving Tree, The Greek and Roman Mythology, Meu Pe de Larania Lima, No Possession, Hope for the Flowers, and Demian. 6) More than half of the male repeated readers read The Tale of Three Kingdoms while female repeated readers tend to read a wider variety of books. 7) Adults read the same books repeatedly to enjoy and learn something.

Objectives: With the increasing number of single households and so-called Honbab-jok, those who eat alone, people tend to enjoy convenient and simple meals, such as single dish meals. This study was performed to provide data on the energy and nutrient content, and nutritional adequacy of single-dish meal. Methods: From the literature reviews, 61 types of single-dish meals were selected, and divided into 4 groups (steamed rice, noodle, porridge, and sandwich burger), and a further 11 sub-groups (bibimbab, fried rice, topped rice, rolled rice/ warm noodle, cold noodle, seasoned noodle, dukgook/ porridge/, and sandwich, burger). In addition, 382 junior high school students from Gyeonggi, Sejong, Jeonbuk, and Chungnam areas were recruited for the survey. The survey questionnaires were composed of the characteristics, preference, and intake frequency of single-dish meals. The representative energy content (arithmetic mean) of single-dish meals were calculated, and compared with the energy contents of preference and intake frequency-weighted values adjusted. The representative nutrient contents, energy contribution ratio, and INQ (index of nutritional quality) of a single-dish meal were calculated for a nutritional adequacy evaluation. Results: The study subjects considered a single-dish meal as tasty, simple and fast to prepare, inexpensive, nutritious, and no low calorie food. The preference scores of all but 1 sub-group of singledish meals were ${\geq}5.00$ (5.00~5.97), and 1 sub-group (porridge) was 4.67 on a 7-point scale. The intake frequency of 11 sub-groups were 0.31~1.71/week, porridge was the lowest at 0.31 and warm noodles was the highest at 1.71. Fried rice, rolled rice, and warm noodle' intake frequency were ${\geq}1/week$. The representative energy of steamed rice, noodle, sandwich burger were 443, 429, and 428 kcal, respectively, and that of porridge was 264 kcal. Less than 5% differences in the representative energy of 4 groups were observed when adjusted for the preference or intake frequency-weighted values. The energy contribution ratio of macro-nutrients calculations showed that porridge was a high carbohydrate and low fat food, whereas sandwich burger were high fat and low carbohydrate foods. The INQ of calcium and vitamin C were less than 1.0 in all 4 food groups, but the INQ of protein and thiamin were > 1.0 in all 4 single-dish food groups. Conclusions: The representative energy in the 4 groups of single-dish meal was 264~450 kcal, which is a rather low calorie meal, and the energy contribution ratio of macro-nutrients were inadequate. The protein and thiamin levels were sufficient but the calcium and vitamin C levels were insufficient in all 4 groups of a single-dish meal judged by the INQ. The additional intake of fruits and milk dairy products between meals with a single-dish meal, supply of calcium and vitamin C may increase, which will result in an improved nutritional balance.

The purpose of this study is to examine the satisfaction for college life and oral prophylaxis subject and improve the satisfaction for this subject by satisfying students' desire through the results of correlation, and to inspire a professional sense by helping students enjoy healthy college life. In order to achieve these purposes, 127 senior students of the Dental Hygiene Department, Kwangju Health College took part in this study to examine the satisfaction for a study course, a lab, professors, a college, and subjects. The following results were obtained. 1. The overall satisfaction for the Dental Hygiene Department was 2.83 and the highest dissatisfaction factors included difficult subjects and non-aptitude. The overall satisfaction for professors was 3.33 and students wanted professors' human contact with students and a well-prepared lecture. The overall satisfaction for college life was 2.65, suggesting not very high satisfaction, and the highest dissatisfaction factors included similar life to high school and surrounding environment. 2. The overall satisfaction for theory was 3.83 and for practice was 3.91 in oral prophylaxis. While the highest satisfaction was found in 'the objective and direction of class' and 'class and a supplementary lesson in not giving a lecture', the lowest satisfaction was found in 'experience in reading textbook-related materials or books'. 3. The correlation of the satisfaction of theory and practice of oral prophylaxis was examined. The satisfaction of oral prophylaxis theory was positively correlated with a school course, professors, and college, while the satisfaction of oral prophylaxis practice was positively correlated with a school course, professors, college, satisfaction of oral prophylaxis theory, and present health condition(p<0.05). 4. Factors influencing the satisfaction for the theory of oral prophylaxis included professors, while factors influencing the satisfaction for the practice were statistically significant in professors and health condition(p<0.05). Based on these results, in order for professional dental hygienists to be developed as professionals serving society, it is recommended to enhance the satisfaction for an oral prophylaxis subject and that professors should provide warm-hearted support and become a role model as an educator.

In this paper, we describe interactive contents which is used the result of the inputted interface recognizing vision-based body gesture. Because the content uses the imp which is the common culture as the subject in Asia, we can enjoy it with culture familiarity. And also since the player can use their own gesture to fight with the imp in the game, they are naturally absorbed in the game. And the users can choose the multiple endings of the contents in the end of the scenario. In the part of the gesture recognition, KINECT is used to obtain the three-dimensional coordinates of each joint of the limb to capture the static pose of the actions. The vision-based 3D human pose recognition technology is used to method for convey human gesture in HCI(Human-Computer Interaction). 2D pose model based recognition method recognizes simple 2D human pose in particular environment On the other hand, 3D pose model which describes 3D human body skeletal structure can recognize more complex 3D pose than 2D pose model in because it can use joint angle and shape information of body part Because gestures can be presented through sequential static poses, we recognize the gestures which are configured poses by using HMM In this paper, we describe the interactive content which is used as input interface by using gesture recognition result. So, we can control the contents using only user's gestures naturally. And we intended to improve the immersion and the interest by using the imp who is used real-time interaction with user.
