Purpose : The purpose of this study was to investigate the effect of ankle strengthening exercise combined with sling-assisted gluteus medius strengthening on ankle instability score, and static and dynamic balance ability, muscle strength in adults in their 20s with chronic ankle instability. Methods : Twenty-eight adults in their 20s with chronic ankle instability were recruited. After screening test, they were randomized through R studio program as an experimental group (n=14) to apply an ankle strengthening exercise combined with sling-assisted gluteus medius strengthening and a control group (n=14) to apply ankle strengthening exercise. The intervention lasted two times a week for 6 weeks. To compare the intervention effects, the Cumberland ankle instability tool (CAIT) score, static and dynamic balance ability, and muscle strength of lower extremities were measured. Results : The experimental group showed a significant increase in pre and post-intervention Cumberland ankle instability tool (CAIT) score, static and dynamic balance ability, and muscle strengt (p<.05). The control group showed a significant increase in pre and post-intervention CAIT score, dynamic balance ability, and muscle strength (p<.05). The experimental group showed a significant increase in CAIT score, dynamic balance ability, and muscle strength compared to the control group (p<.05), and showed a high effect size. Conclusions : The results of this study confirmed that ankle strengthening exercise combined with sling-assisted gluteus medius strengthening on people with chronic ankle instability the possibility that it could be effective in improving ankle instability and improving dynamic balance ability, and strength by movement. Although additional research is needed to increase the number of participants due to the small sample size, it is hoped that this study will be an optimistic clinical protocol for people with chronic ankle instability.

The study investigated the recognition and preference of foreigner to Korean foods in different nationality. Questionnaires consisted of two languages- Chinese and English were given to 180 residing foreigners in Insa-dong and COEX mall areas and interview methods were used. A total of 157 questionnaires were analyzed for statistical analysis. The statistical analysis was completed using SPSS Win(ver 11.0) for descriptive analysis, ${\chi}^2-test$, ANOVA and Tukey's test. Main results of this study were as follows: First, the factors foreigners considered when they chose food of other countries were; 1.new taste, 2.curiosity, 3.foreign culture, 4.foreign tradition. People from European and Asian countries were inclined to 'New taste' first, while people from American and Oceanian countries were inclined to "curiosity". Second, most of respondents have tried Bulgogi and Galbi before and many of them also have tried Kimchi, Kimbop, and Bibimbop as common Korean foods. Third, the preference was different according to their origins. Asian people liked diverse cuisines including Bulgogi, Galbi, Kimchi, Dubu Doenjan chige, and Samgaetang, while European and Oceanian people liked Bulgogi, Galbi, and Bibimbop. The preference for Kimchi was considerably high among Asian people, however, low among American and Oceanian people(p<0.05). Fourth, Deviation was little on the taste, color, and table settings of Korean foods; most of the respondents was satisfied on those factors. European and Oceanian people who were familiar with table setting according to time were satisfied at table setting of Korean foods, which focused on space, rather than time. Fifth, most of the respondents, especially Asian people, remarked that Korean foods were spicy. The opinion on the taste of Korean foods was variable according to their nations. Currently many of culinary companies from Korea were leading their active business in foreign countries such as China and United States.

Most of the ear shells of hearing aids are manufactured manually, and it is one of the reasons that the cost of the custom-made hearing aids can be increased. Thus it is required to manufacture the ready-made ear shell for the purpose of easy manufacturing and decrease in cost. In this study, we extract parameters in order to manufacture the ready-made ear shell for CIC type hearing aids and simulate to reconstruct the ear shell using the extracted parameters. To parameter extraction, we set up the eleven parameters for the ready-made ear shell based on anatomical characteristics of the ear canal, and we found values of the parameters from twenty-one impressions in their 20s and twelve impressions in their 60s using aperture detection and feature detection algorithms. Classifying the parameters by size, we also determine the parameters of ready-made ear shell into three types for people in their 20s and two types for people in their 60s. Each ready-made ear shell was simulated to reconstruct using figured parameters, and evaluated the rate of agreement with unused impressions for setting parameters. To evaluate the ready-made ear shell, we calculate the volume ratio and intersection between of the each impression and ready-made ear shell, and the intersection ratio using the intersection volume and ready-made ear shell volume. As a result, the volume ratio was about 70%, and volume match ratio was also up to 70%. It means that the ready-made ear shell we simulated is the significantly matched to impression.

Objectives: This study was conducted to assess dental health states of disabled people and analyze association between perception and awareness toward dental health and dental health status. Methods: The survey was performed from June 25 through October 30, 2004. A total of 548 disabled people participated in the study with details of 419 living in eight residential care centers located in Gyeongsangbuk-do and 129 children from a special school and two day-care centers. All subjects underwent oral examination and surveyed through a questionnaire. Parents of 129 children with disabilities were also surveyed through a separate questionnaire. Results: The dental caries experience rate was 82.1% of total 548 subjects. By age, those in their 20s experienced a high rate of dental caries with 87.5%. By educational level, those with a middle school education experienced a high dental caries rate with 91.8% (p<0.05). Of total subjects who experienced dental caries, 78.9% had experience in dental caries treatment. By age, those in their 10s showed a high rate of dental caries treatment with 87.4%(p<0.05). By educational level, those with a high school education showed a high rate of dental caries treatment with 87.7%(p<0.05). Those in residential care centers had a high rate of dental caries treatment with 82.1%, which is significantly higher than 68.8% of those who used day-care centers. A tooth extraction rate was 38.0% of total subjects. Those in their 40s had a higher rate of tooth extraction(p<0.01). Those in residental care centers had a significantly higher rate of extraction with 43.4%, compared with 20.2% of those in day-care centers. Of total subjects, 61.5% had plaque. A high rate of plaque formation was observed in those in their 40s(92.0%), those with a high school education(84.0%) and those with multiple disabilities(77.8%)(p<0.01). Among total subjects, 47.6% maintained healthy periodontal tissue. Those in their 40s and those with multiple disabilities had diseased periodontal tissue(p<0.01). Of 129 disabled children, 43.8% had plaque with parents who were not oral health-conscious while 18.6% had plaque with parents who were oral health-conscious, showing a significant difference(p<0.05) Conclusion: The results of the study suggest the need for educating parents with disabled children about oral health and strengthening programs for oral health for teachers working at special schools and day-care centers.

Nowadays people are turning to have a more intimate environment-friendly lifestyles. In the clothing industry they are focusing on making products that are more human-friendly and not harmful to the environment. In the midst of the spread of consumption research is being done to develop manufacturing textiles that do not induce pollution. For instance, advantages of the natural textile fibers, cotton, silk, and ramie, have been newly recognized in terms of environment-friendliness, Together with these fibers, the natural high molecular materials, such as chitosan and hyaluronic acid, have found new roles in the application sectors of human-friendliness and environment-friendliness. Products using these substances and processing methods can make the products more wearable, have high sensitivity, make people feel aesthetic appreciation for the products, and make them appreciate the value of a more healthier environment. In a survey according to subjects in their 20s and 30s, their preferences towards their consciousness and awareness of the development of materials as well as their attitude towards environment-friendly products were determined as a conclusion. It was shown that consumers that are more conscious about the interest of the environment as well as the problems concerning the environment were more intent on buying products that were environmentally-friendly. Women have shown more active and positive attitudes towards the importance of the awareness of the environment in comparison with men. Generally, consumers in their 20s and 30s preferred the feel of materials that were less than 1% concentration process than those of materials that were 1% concentration process. To increase the "rustly" feeling of the materials, it was found that 1% concentration process was suitable for manufacturing.

The Royal United Services Institute(RUSI) was founded in the middle of the 19th century in Britain. It was developed through 'Naval Historical Revitalization Movement' in that time. Many celebrities and people who were interested in the Navy participated in the activities of the RUSI. For example, the forums and lectures were held by prestigious persons, like Sir Garnet Wolseley and the Duke of Cambridge. It also became the milestone for guiding the flow of the Royal Navy's thought with the Naval Intelligence Department and the Naval Records Society. The forum of the RUSI was the place for debating naval hot issues. The journal of the RUSI was the space for suggesting an idea and gathering public opinions for developing Britain's sea power. Therefore, the RUSI was the public sphere for the Royal Navy in the 19-20th Century. And especially, the paper prize contest of the RUSI was the culmination of the RUSI's activities for the Royal Navy. Naval prize essays gave messages to the Royal Navy about the changing situation of European naval powers. Also, they made many meaningful debates for the Royal Navy to overcome the difficult situations in that time. Those essays were reflecting the issues of the Royal Navy and leading the way for getting over it. Besides, some people appeared through the contest and they played important roles for making the contingency and planning the war. The contest reflected the past, anticipated the future, and selected the talented persons to shape the future. This developing aspects of the RUSI could apply to the Korea Institute for Maritime Strategy(KIMS). The KIMS already carries out the role of the RUSI very similarly. If the KIMS changes to the way for open-door policy to more people, it will work more efficiently for their goal. In this respect, the messages of the RUSI will be very useful for improving the activities of the KIMS.
