We examined the relationship between the extent of Facebook usage and social well-being with consideration of cyberbullying involvement using a person-oriented approach. Survey data were collected from a sample of 312 secondary students from Grades 7 and 8 in Hong Kong. Levels of cyberbullying involvement, Facebook usage and perceived social support were investigated. Participants were classified into three clusters based on the different levels of Facebook usage and cyberbullying victimization through cluster analyses (i.e., frequent Facebook user/noncyberbullied victim, frequent Facebook user/cyberbullied victim, and uninvolved). Our results showed that frequent Facebook users who are cyberbullied tend to engage in cyberbullying perpetration significantly more than the frequent Facebook users who are not cyberbullied, even when the latter reported higher Facebook usage. This result provides some support for the idea that cyberbullying victimization has additional value on top of the level of usage in explaining one's participation in cyberbullying perpetration. As expected, frequent Facebook users who were not cyberbullied reported the highest perceived social support among the three groups. What is even more interesting is the equal level of perceived social support found between the cyberbullied victims and the uninvolved. Our results suggest that, although limiting adolescents' Internet use might reduce their risks of being involved in cyberbullying, it might also take away the potential benefits they could get from interacting with the online community. Benefits of using the person-oriented approach in the study of cyberbullying are discussed.

The purpose of this study was to identify the pratical applicability of person-situation benefit segmentations of the female apparel market in Seoul by a prior segmentation method. The specific objectives of this study were 1) to identify the useful demographic variables for person-situation benefit segmentations of the female apparel market, 2) to assess that person- situation benefit segmentations of 1.he female apparel market are accessit)le by developing a profile of each segment based on the interactions of situation and personal characteristics on perceived risk, importance of store attributes and store-type choice, and on brand type prefered by each segment. 3) to assess the validity of person-situation benefit segmentations of the female apparel market in terms of easy accessibility. The data were collected via a questionnaire from 601 housewives of ages 20's to 50's living in Seoul, Korea. The data were analyzed by factor analysis, repeated measure two- way ANOVA and X2-test. The results of this study were as follows. First, the age-by-situation segmention basis and the education-by-situation segmention basis were useful for person-situation benefit segmentations of the female apparel market. Second, there were found three benefit segments (Youth/Fashion oriented users, Brand oriented users and Apathetic users of clothing) using age-by-situation segmention basis. Using education-by-situation segmention basis, five segments (Economic-value, Youth/Fashion, Brand/Self-expression Self-expression, and Apathetic users of clothing) were identified. And beifit segments classified by the age-by-situation segmention and education-by-situation segmention approach were accessible. Third, the pratical applicability of person-situation befeift segmentations of the female apparel market by a prior segmentation method were suggested.

This study aims to suggest a new algorithm for detecting two-wheelers on road that have various shapes according to the viewing angle for vision based intelligent vehicles. This article describes a new approach to two-wheelers detection algorithm riding on people based on modified Histogram of Oriented Gradients (HOG) using correlation coefficient (CC). The CC between two local area variables, in which one is the person riding a bike and other is its background, can represent correlation relation. First, we extract edge vectors using HOG which includes gradient information and differential magnitude as cell based. And then, the value, which is calculated by the CC between the area of each cell and one of two-wheelers, can be extracted as the weighting factor in process for normalizing the modified HOG cell. This paper applied the Adaboost algorithm to make a strong classification from weak classification. In this experiment, we can get the result that the detection rate of the proposed method is higher than that of the traditional method.

Vulnerable road users such as bike, motorcycle, small automobiles, and etc. are easily attacked or threatened with bigger vehicles than them. So this paper suggests a new approach two-wheelers detection system riding on people based on modified histogram of oriented gradients (HOGs) which is weighted by curvature and local correlation coefficient. This correlation coefficient between two variables, in which one is the person riding a bike and other is its background, can represent correlation relation. First, we extract edge vectors using the curvature of Gaussian and Histogram of Oriented Gradients (HOG) which includes gradient information and differential magnitude as cell based. And then, the value, which is calculated by the correlation coefficient between the area of each cell and one of bike, can be used as the weighting factor in process for normalizing the HOG cell. This paper applied the Adaboost algorithm to make a strong classification from weak classification. The experimental results validate the effectiveness of our proposed algorithm show higher than that of the traditional method and under challenging, such as various two-wheeler postures, complex background, and even conclusion.

This paper discusses a new perspective in health approach and the effect of health life on health status, and suggests some points to be improved in the establishment of health policies hereafter. Today's health problems changed from the acute epidemic diseases caused by simple factor to the multifactorial chronic diseases. Therefore, the health approach tries the holistic health approach, that is, the integrative approach by the interdisciplinary cooperation. With the advent of holistic health and holistic medicine in 1970's, the behavioral medicine was born in 1977, which is the interdisciplinary field concerned with the development and integration of behavioral and biomedical science knowledge and techniques relevent to prevention, diagnosis and treatment. As a means to the reducement of the unnecessary medical utilization and medical expense, the medical self care and self-help movement is well under way in the countries of America, England, and Canada, in which lay persons are encouraged to actively function for themselves to prevent, detect and treat common illnesses and to promote positive health habits through the health activation programs such as The Course for Activated Patients and The Health Activated Person. This study shows that the individual health life gives great positive effect to his health status with the reducement of medical expense. These above facts suggest that the preventive health programs such as health education should be developed and strengthened instead of medical care-oriented health policy.

History of the Sensibility Ergonomics is explained. Concepts, definition, and research methods on the human sensibility are proposed for systematic applications of human sensibility studies to product and environment developments. Sensibility Ergonomics was born in socio-technological environments where consumers required aesthetic and satisfactory products in addition to useful and usable ones, and manufactures were trying to develop consumer-oriented, user-friendly products. Sensibility Ergonomics is defined as "multi-disciplinary and inter-disciplinary processes for developing products and environment as usable, comfortable and satisfactory with the information on human sensibility." Human sensibility is functionally defined as "feelings generated when perceived sensory and information stimuli are reflected from memory which has been accumulated through personal experiences." Human sensibility is affected by at least three factors: personal, social, and cultural. Consumers evaluate products in three aspects : functional, sensorial, and cultural sensibilities. Human sensibility is personal, dynamic, and ambiguous. It is generated reflectively and intuitively against external stimuli. No Physiological responses are accompanied, and one cannot control his/her sensibility. However, the sensibility affects the decision making or behavior of the person. To understand the human sensibility many inter-disciplinary methods should be used instead of one-variable approach. Micro-scopic studies such as Questionnaire, interview, behavioral analysis, and psychophysiological experiments can be performed. In addition, social and cultural studies are essential to understand an individual's sensibility. Results of sensibility studies can be applied to setup new interactions between human and machine through sensible(or affective) human-machine (computer) interfaces. Human-oriented and user-friendly products can be made with the information on human sensibility.

Communication breakdown has been mentioned causing a heavy burden for dementia caregivers. This study aims to inspect and structure the process and results of communication between people with dementia and their caregivers. The impeding/facilitating elements of communication are also extracted. Interviews with 21 of dementia care experts about the direct and indirect experiences of communication with people with dementia were analyzed based on the grounded theory. Results show that combination of the cognitive and communication decline of the people with dementia, confusing environment and caregivers' inappropriate attitude and lack of communication skills leads to communication breakdown and relations severance. Minimal contacts and task-oriented conversation results in conflicts and people with dementia's increasing agitation, anxiety and violent behaviors while understanding of individuality and listening with heart lead to recovered lucidity in the state of serious dementia, recovered pleasure and voluntary participation in the daily activities for people with dementia. Core paradigm was defined as 'Person Centered Care through relation formation'. There are 4 types of communication with people with dementia : partnering, patronizing, conflicting, avoiding types. Researchers suggest that Person Centered based communication skills be educated and trained for dementia caregivers.

The purpose of this study is to determine the effect of a convergence approach, which applies both home environment modification applied with assistive technology and task-oriented intervention using a fall safety checklist, on the fall efficacy and activity level of stroke patients. 41 persons with stroke(21 experimental groups and 20 control groups) were divided into experimental and control groups. The experimental group was applied environmental modification and the task-oriented intervention using the fall safety checklist for 4 weeks. The control group was provided only the environmental modification. Before and after the intervention, the Korean Activity Card Sort (KACS) and the Korean Falls Efficacy Scale-Korean version (FES-K) were used for evaluation. There was no significant difference in fall efficacy and activity level change between the experimental group and the control group. Both the experimental group and the control group significantly improved the fall efficacy and activity level after the intervention. By applying the results of this study to the clinical field, it will be possible to support stroke patients to live safely and actively participate in the community.

In case of the hearing impairment with tinnitus and increased sound sensitivity, it is known that the patients tend to appeal the psychologically oriented social handicap rather than communication disability. The audiologist who is responsible for such patients in aural rehabilitation should pay special attention to the counseling techniques including tinnitus retain therapy (TRT), ear protector, noise generator, or specific acoustic training based on close cooperation and rapport. And then the audiologist should try to lessen their reaction to the tinnitus by using a hearing aid. This therapies tries to focus not a. total approach but a treatment to lessen the severity of tinnitus. This paper as a case report that a unilateral sharply slopped sensorineural hearing impaired person with tinnitus and increased sound sensitivity by using four channel digital signal processing (DSP) hearing aid with programming increment at low level (PILL).

Librarians, who work for University libraries in Korea experience a lot of confusion and difficulties because of rapidly-changing technological conditions and under-developed understanding of the University Libraries' full potential on the part of the users. I present the concept of 'Subject Services' as an approach which librarians could use to overcome these difficulties in their own way. The 'Subject Services' refers to the 'subjectized' collection development and reference services, which can more specifically address the users' needs. To make this idea more concrete, I selected Pusan National University Library as the case of my qualitative research. And I made use of various research techniques such as 'participant observation' and 'ethnographic interview'. After looking into the case library in depth, I found that the concept of 'Subject Specialist'. a person who has double master's degrees including that of library and information science, is more suitable to the University Libraries in Korea at the present developmental stage. At the end of this article, propose that the development of Core Collections, the improvement of subject-oriented reference services and the continuing education of librarians should be emphasized.
