Fuzzy Controller is a system that displays a person's thoughts using membership function and IF-THEN rules. With the help of specialists' knowledge, rule bases can be explained in easy language. Furthermore Fuzzy Controller has strong resistance against turbulence. Its performance is especially prominent when targets cannot be measured in mathematic methods because the fuzzy controller can measure the output using only the relations between the input and output. With the increasing influence of multimedia on our daily lives, vision plays bigger role both in industries and personal lives. Like wise vision is being used in many areas such as detecting and identifying objects. It is difficult to detect and control targets because there is a delay in the calculating when using vision in detecting and controlling objects in large quantity. In this paper we showed how to use fuzzy controller in minimizing the calculation process, controlling target objects and moving view window instead of applying input variation through vision. Ball beam, which has strong nonlinear, was used as the target object and DSP320C6711 IDK by TI(Texas Instruments) company was for the benefit of speedy calculation and vision data operation.

Background: The purpose of this study is to determine how the cognitive state of the elderly influences the activities of daily living(ADL) in order to increase their achievement capacity and their ability to exercise this capacity in daily life. The MMSE-K(Mini-Mental State Examination-Korean) was used to evaluate the daily activities and cognitive state of a group of subjects more than 65 years of age. The goal was to understand (1) How their achievement level in their daily activities changes according to the increase and decrease of their cognition points by analyzing and comparing their achievement points in the mental state examination, and (2) What variables influence that daily achievement level. Methods: The survey was conducted by a group of students from AnSan College who were trained for this method of data collection. The group surveyed 224 senior citizens older than 65 to determine their ADL performance. The subjects were selected from Silver Care Centers in the Gyounggi Province area including centers in Suwon, Anyang, Kwachun, and Sanbon City. The subjects were given enough information to fully understand the purpose of the study and the method by which it would be conducted. The survey method was a direct interview: which involved an interviewer reading the questionnaire to the subject and recording the answer. Result: The following results were calculated using SPSS WIN ver. 13.0: In the lower score of the MMSE-K regarding ADL performance (K-MBI) for activities such as individual hygiene, bathing activity, food activity, toilet management, going up stairs, getting dressed ad undressed, controlling stools and urination, walking, and chair/bed movement, most of the subjects responded that they could not perform these activities by themselves (p<.01). In the higher scores for the same activities, most response that they could perform the tasks by themselves (p<.01). In the results of the multiple regression analysis, there influence of the variables for ADL performance (K-MBI) and MMSE-K score was higher for females than males. Conclusion: This study evaluated the cognitive state of the elderly using the MMSE-K, which is the most convenient method, and examined how the cognitive state influences the achievement capacity of the daily lives with other variables. In conclusion, the higher the score on the MMSE-K, the more independent the elders are in the activities of daily living, especially among women more than men.

PURPOSE: The aim of this study was to provide the standard value of the Five Times Sit to Stand Test (FTSST) measurement on the daily life independence of the elderly in Korea and examine the effects of this test on their daily lives. METHODS: This study was conducted on elderly people over 65 years of age living in Gyeongsangbuk-do, Korea. FTSST was performed while sitting position on a chair. The subjects were classified into independent and dependent living groups according to their lifestyle, and their influence was then examined through logistic regression analysis. To determine the usefulness and cut-off value of the FTSST, the analysis was performed using the ROC curve. RESULTS: The elderly were more likely to live in a group rather than independently as the FTSST time increased (p<.05) (OR=1.098). The area of the lower part of the ROC curve was .707, and as the FTSST increased, a subject was more likely to live in a group rather than independently (p<.05). The cut-off value was assigned to the point where both the specificity and sensitivity were at the coordinates. The sensitivity and specificity were .626 and .753, respectively at 15.62 seconds. CONCLUSION: The elderly in Korea are more likely to live a group-dependent lifestyle than live independently; the likelihood of this outcome is increased further for every additional second beyond 15.62 seconds. The loss of independence of daily life could be predicted based on the status of a subject's lower leg strength using the FTSST.

This study surveyed 266 housewives residing in a Gyeonggi-provincial area for their dietary attitudes, dietary habits, nutrition knowledge, and application of nutrition information to daily life according to whether they use nutrition labeling. The survey on the dietary attitudes of the subjects showed that the points of "think that nutrition affects health", "quite interested in nutrition and health information", "like developing and trying new diverse recipes", and "persistently try new foods" were higher among those who check out nutrition labeling (Check group, n=112) than those who do not check out nutrition labeling (No check group, n=154). Reason for snacking, the Check group reported higher in the reasons of "for taking nutrients" but lower in the reasons of "do not eat enough meal" and "impulsively" than the No check group (p<0.01). Asked about why they check the nutrition labeling, the Check group answered "to compare products with each other" and "to purchase healthy food" whereas the No check group said "to decide whether the food is safe or not" and "to reduce body weight" (p<0.01). The Check group showed more recognition on the significance of the nutrition labeling and application to their actual daily lives than the No check group. Therefore, our results suggest that proper use of nutrition labeling is expected to improve dietary attitudes and dietary habits as well as enhance the application of nutrition information to actual daily life and promote health not only for the housewives but also for their family members as well.

This study aims to provide definitions and standardization for necessities that elderly people can use conveniently and properly in their daily lives and classify necessities for different purposes. First, standard terminologies were defined by reviewing the literature and the relevant laws related to daily necessities for the elders. Secondly, a concept for necessities for the elders was also defined through consultation with experts. Lastly, the elderly's necessities were selected and classified. The elderly's necessities are defined as aids that ordinary elderly people in normal aging process need for the purpose of the convenience of life and aids they wear or use to maintain or improve their health. In this study, the elderly's necessities are divided into three categories: necessities of health, necessities of Oriental medical aids and necessities of daily living. Each category is further classified as follows: Necessities of health include aids for personal medical treatment, aids for personal care and protection and aids for recreation. Necessities of Oriental medical aids include aids for personal medical treatment, aids for personal care and protection and others. Necessities of daily living include aids for personal care and protection, aids for personal mobility, aids for housekeeping, furnishings, aids for communication, information and signalling, aids for handling products and goods and aids for recreation. The classification of the elderly's necessities in this study can be used as basic information for further studies of demand for necessities for the elderly. The results will lay the foundation for a standardization system for the elderly's necessities and the development of silver industry.
