We propose a smart human-computer interface replacing conventional mouse interface. The interface is able to control cursor and command action with only hand performing without object. Four finger motions(left click, right click, hold, drag) for command action are enough to express all mouse function. Also we materialize cursor movement control using image processing. The measure what we use for inference is entropy of EMG signal, gaussian modeling and maximum likelihood estimation. In image processing for cursor control, we use color recognition to get the center point of finger tip from marker, and map the point onto cursor. Accuracy of finger movement inference is over 95% and cursor control works naturally without delay. we materialize whole system to check its performance and utility.

The study surveyed 1,127 mothers whose children aged 3 to 5 went to 25 randomly selected kindergartens, which were located in Busan Metropolitan City and the adjacent Gimhae City, and analyzed the preventive health behaviors on their children and the condition of home health education on their children. As the compulsory kindergarten education will e to be implemented within 4 years, this study aimed to draw up the rudimentary material for health education at kindergartens. The study results are summed up as follows: 1. Mothers' awareness of health-related attitude and behavioral level for their children at kindergarten: 1) The general health condition of the children, which mothers are aware of, was that they were healthy on the whole. As their children becomes older, the income level of the parents is lower, and mothers have lower level of educational standard, the health condition of the children was found a little lower. 2) In terms of mothers' recognition of the practice level of preventive health behaviors, the items such as going to bed regularly, washing hands and feet well, and having meals regularly were high in the practice level, while exercise and tooth-brushing were not practiced well. 2. The condition of mothers' health education of their children: 1) It was found that washing hands and feet, restriction of overeating and preference for specific kinds of food, guidance on regular sleep and regular meal were practiced well among items of home health education targeting kindergarten children. 2) Mothers have obtained information on family health from printed matter such as newspaper or magazine rather than the visual media. 3) From the cross analysis of mothers' health education on children and children's health behaviors, as the standard of education of mothers was higher, so was the level of preventive health behaviors of children. 3. From the result of multi regression analysis of the factors influencing the preventive hygiene of kindergarten children, it was found that as the home health education level was higher, so was the health behavior of children. On the other hand, as the mothers were older, the health behavior of children became lower.

Recently, HTML5 have drawn many people's attention since it is considered as a next-generation web standard and can implement a lot of graphic and multimedia-related techniques on a web browser without installing programs separately. In this paper, we implement a game independent of platforms, such as iOS and Android, using the HTML5 canvas. In the game, the main character can move up, down, left, and right not to collide with neighboring enemies. If the character collides with an enemy, the HP (hit point) gauge bar reduces. On the other hand, if the character obtains heart items, the gauge bar increases. In the future, we will add various items to the game and will diversify its user interfaces by applying computer vision techniques such as various gesture recognition.

This study reinterpreted the value of traditional communities in rural areas and explored ways to revitalize sustainable communities. To do this, we surveyed the members' perceptions about the activities of the community organization as assessed through a questionnaire. The questionnaire items focused on the participation, satisfaction and contribution of the members of the community organization, with additional questions investigating the idea of the community vitalizations plan. A self-report questionnaire survey was administered to 321 members of the community, and the results were analyzed through technical data, t-test and ANOVA analysis by using the SPSS program. In the results, the perceptions of the members of the traditional village community differed significantly according to socio - demographic factors and member recognition characteristics. Especially, males were more voluntarily and positively compared to females, and the lower the age of satisfaction, the lower was the perceived individual satisfaction with community activities. In the case of perceived contributions to individuals and the community, the participants perceived positively in the emotional support for the individual's participation in the organization. On the other hand, the results confirmed that the contribution to the local community is important in realistic aspects such as regional vitalizations. It is confirmed by the decrease in the number of members in response to the difficulty of the organization. (Ed- 'the lack of the size of the membership' simply repeats 'the decrease in the number of members'; thus it's unnecessary).

This study was designed to examine the degree of dependence on dietary environment, evaluate the perception of metal service program and investigate factors affecting the demand for meal service programs for elderly parents. The purpose of this study provided the basic information for the development and systemization of meal service program for elderly. Eight hundred twenty semen adults who have elderly parents were surveyed using pre-designed written questionnaire. According to the results on the life environments of their elderly parents, psychological factors(41.7%), living condition(14.3%) and dietary environment (13.2%) had trouble. Physical and psychological conditions significantly affected the dietary environment(p<0.05). Only 9.2% of the subjects were already aware of recognized the meal service program for elderly, and the degree of recognition differed significantly by sex and education level. Women had better perception of meal service program for elderly than men. In men, they would expect to use congregate meal service(44.1%), home-delivered meal service (23.7%), nursing home meal service(16.9%) in order. On the other hand, for women, home-delivered meal service (41.2%), congregate meat service(44.1%), and nursing home meal service (16.8%) in order. Therefore there are significant differences between men and women what type they want(p<0.001). For those who haute both of the parents or either one of them, they would use more of congregate meal service (38.8%) and home-delivered meal service (38.8%) than nursing home meal service (15.5%). The group whose parents are lower socio-economic status would have tendency to use the nursing home meal service (p=0.06). The group of whom believe the dietary environment is the problem of their parents'life environment had preference of using congregate meal service and home-delivered meal service.

Carlos Jimenez's 'House and Studio' was self-designed to fully function as both a home and workplace. Since its establishment in 1983, the installation has been continuously updated for almost 30 years solely under the guidance of the owner's life occurrences and routine needs. The additions and alterations succeeding the building's erection were executed to incorporate small yet symbolic fragments of the resident's memories and life episodes. The particularity of the 'House and Studio' can be compared with other residential remodeling and expansion projects in regards to certain key aspects. These means of comparison include, but are not limited to, building strictly under the direction of a master plan of development vs. allowing natural adaptations that comply with the resident's needs, rapid development vs. gradual advancement, the ornamenting by exposing showy features vs. the enhancing by addition of modest natural components, sustainability vs. sustenance, systematic room divisions vs. ambiguous spatial organization, possession as a materialized asset vs. preservation as a recollection of memories, and finally the recognition as one example of signature architecture vs. the witnessing of a maturing animated shelter. The given propositions can be further explained with the comprehension of Erich Fromm's theory of the 'Having' mode and 'Being' mode, two mechanisms that categorize the essence of human life. The 'Having' mode is described by the human greed for wealth, power, and influence, whereas the 'Being' mode is comprised of compassion, joy, and productivity. Fromm's thesis applies to the general sense of human life, but the ideas can be narrowed to accommodate the architectural standpoint. In architecture, the 'Having' mode can be translated to be the conspicuous form-oriented and self-contained object. The 'Being' mode, on the other hand, is transposed as the more natural form, incorporating the needs of the owner before commercialization. The growth of Jimenez's 'House and Studio' can be perceived as an architectural suggestion to the overcoming of human indifference caused by fixation on the 'Having' mode.

This study attempts to establish a system extracting and monitoring cultural grounds of seaweeds (lavers, brown seaweeds and seaweed fulvescens) and abalone on the basis of both KOMPSAT-2 and Terrasar-X data. The study areas are located in the northwest and southwest coast of South Korea, famous for coastal cultural grounds. The northwest site is in a high tidal range area (on the average, 6.1 m in Asan Bay) and has laver cultural grounds for the most. An semi-automatic detection system of laver facilities is described and assessed for spaceborne optic images. On the other hand, the southwest cost is most famous for seaweeds. Aquaculture facilities, which cover extensive portions of this area, can be subdivided into three major groups: brown seaweeds, capsosiphon fulvescens and abalone farms. The study is based on interpretation of optic and SAR satellite data and a detailed image analysis procedure is described here. On May 25 and June 2, 2008 the TerraSAR-X radar satellite took some images of the area. SAR data are unique for mapping those farms. In case of abalone farms, the backscatters from surrounding dykes allows for recognition and separation of abalone ponds from all other water-covered surfaces. But identification of seaweeds such as laver, brown seaweeds and seaweed fulvescens depends on the dampening effect due to the presence of the facilities and is a complex task because objects that resemble seaweeds frequently occur, particularly in low wind or tidal conditions. Lastly, fusion of SAR and optic spatial images is tested to enhance the detection of aquaculture facilities by using the panchromatic image with spatial resolution 1 meter and the corresponding multi-spectral, with spatial resolution 4 meters and 4 spectrum bands, from KOMPSAT-2. The mapping accuracy achieved for farms will be estimated and discussed after field verification of preliminary results.

In this paper, we propose a smoker recognition algorithm, detecting smokers in a video sequence in order to prevent fire accidents. We use description-based method in hierarchical approaches to recognize smoker's activity, the algorithm consists of background subtraction, object detection, event search, event judgement. Background subtraction generates slow-motion and fast-motion foreground image from input image using Gaussian mixture model with two different learning-rate. Then, it extracts object locations in the slow-motion image using chain-rule based contour detection. For each object, face is detected by using Haar-like feature and smoke is detected by reflecting frequency and direction of smoke in fast-motion foreground. Hand movements are detected by motion estimation. The algorithm examines the features in a certain interval and infers that whether the object is a smoker. It robustly can detect a smoker among different objects while achieving real-time performance.

In most mail automatic processing centers, after facing and canceling, letter mails are passed through an Optical Character Recognition/Barcode Sorter(OCR/BS) to read the postal code and 3 of 5 fluorescent (luminescent) barcode is applied. Normally, 31%∼35% of this mails are rejected. The main reasons for reading failures are poor printing quality of addresses and barcodes, script printing, writing in a cursive hand, variety fonts, and failure to locate the address. Our goal is to provide mailer with top quality service and customer barcode service as we move toward 100% barcoding automation of letter mail. In this paper, we propose a method of printing 3 of 5 customer barcode, postal code management, and detection of postal code based on postal address for increase the performance of automatic processing system in mail items. Using postal code generating rules, which are automatically extracted from postal addresses and address numbers, creates postal codes. The customer barcode support system is implemented by C++ language and runs on IBM PC under Windows 95.
