분산 컴퓨팅 분야에서 P2P 기술은 네트워크로 연결된 피어들 간에 자원을 공유하기 위한 다양한 방법을 제시하고 있다. 이는 소수의 서버에 의해 자원을 제공하는 중앙 집중적 네트워크 이용 피어에 비해 자원 활용 측면에서 더욱 유용하다. 그러나 이러한 P2P 시스템을 구성하는 피어들은 항상 온라인 상태가 아님으로 시스템 이용자에게 높은 신뢰성을 제공하기 어렵다. 본 논문의 이전 연구에서는 새로운 자원 제공 피어의 선택을 위한 로딩 부담률을 낮추는데 기여하고 있으나 자원을 다운로드 하기위한 작업을 분담하는 피어들을 선택하는 방법이 가장 낮은 작업량의 피어를 선택하는 방법으로 매우 단순하다. 본 연구에서는 피어들의 평균 성공률 평가치를 기반으로 예측에 의한 피어의 오프라인 발생 빈도를 낮추어 높은 신뢰성을 제공하고자 한다.

The purpose of this study is to examine the associated risk factors for adolescent cigarette smoking. In February 1995, a total of 1793 students from 17 general high schools in Seoul were assessed with a self-completing questionnaire pertaining current smoking status and school.family.peer environmental factors. The results are as follows; 1. The overall proportion of current smoker among students in the study was 17.3%; 27.7% in males and 6.6% in females. 2. There was significant association between smoking status and all school environmental factors (ranks at school, satisfaction at school, study hours after school, extracurricular activity) examined. 3. Siblings smoking in males and family structure in females were significantly associated with the smoking status of students. 4. Functional aspect of family environmental factors, such as APGAR score, parental supervision, attachment to father or to mother were related to smoking status of students. 5. Association with friends who smoke was significantly associated with smoking status of students. 6. In males, association with friends who smoke, ranks at school, siblings smoking were significant positive predictors and APGAR score, parental supervision, attchment to mother were significant negative predictors. In females, association with friends whosmoke, ranks at school, satisfaction at school were significant positive predictors and parental supervision, attchment to father were significant negative predictors. These findings suggest that strategies that influence smoking behavior need to be directed not only to the individual student but also to their peer group, family and school environment.

This study investigated whether parental disciplinary practices mediated the status of peer acceptance. From a sample of 420 kindergarteners, twenty were classified as popular children and twenty were classified as rejected children using sociometric assessment and their parents(40 mothers and 40 fathers) were responded to a parental behavior questionnaire Results were as follows: 1. Compared to rejected children, popular children had fathers who participated more actively in child-rearing practices and mothers who were less overprotective in child-rearing practices. 2. Popular children had fathers who were more affectionate and more actively participated in child-rearing practices than mothers were, whereas rejected children had fathers who were more overprotective than mothers were. 3. Reasonable guidance made by parents was uniquely predictive of peer popularity, whereas parental overprotection was the best predictor for peer rejection.

The purpose of this study was to investigate the relationship between abused (physical, emotional & neglect) children and their peer relationships and personality. The subjects were 320 fifth graders from the low-middle class of families in Seoul. The data were gathered by questionnaires and peer nomination method. The major findings of the present study were as follow : (1) Children were physically abused mainly by their fathers, and neglected mainly by their mothers. (2) The significant differences in both peer relationships and personality were found according to the type of abuse. Physically abused children were viewed as either a neglected child or a aggressively rejected child who shows higher activity and impulsivity. But emotionally abused and/or neglected children were perceived as a neglected child who shows lower sociablity. (3) There were statistically significant differences in personality among sociometric status groups.

본 연구의 목적은 사회적 성취목표의 세 가지 유형을 기반으로 초등학생의 사회적 성취목표를 잠재집단으로 분류하고, 각 집단이 또래지위와 공격성에서 어떠한 차이점이 있는지를 탐색하는 것이다. 사회적 성취목표와 사이버 공격성은 자기보고 방식으로, 또래지위와 외현적 공격성과 대인관계 공격성은 또래지명 방식으로 측정하였다. 사회적 성취목표는 사회적 숙달목표와 사회적 수행접근목표, 사회적 수행회피목표로 나누었으며, 또래지위는 지각된 인기와 사회적 선호로, 공격성은 외현적 공격성, 대인관계 공격성, 사이버 공격성으로 구분하였다. 전체 연구 대상은 클래스넷 4차년도 자료 중 학년 비율을 고려해 무작위 추출한 초등학생 1,239명(남 633명, 여 606명)이다. 잠재프로파일 분석을 이용해 사회적 성취목표 유형을 분류한 결과 세 집단이 적합한 것으로 나타났다. 사회적 성취목표의 세 집단은 각각 '숙달지향 성취목표형(184명, 14.9%)', '평균 성취목표형(852명, 68.8%)', '고사회적 성취목표형(203명, 16.4%)'으로 명명되었다. 다항 로지스틱 회귀분석을 이용해 또래지위 및 공격성 간의 관련성을 살펴본 결과 1차 시기 사회적 선호가 높을수록 고사회적 성취목표형 집단에 속할 확률이 낮았고, 사이버 공격성이 높을수록 숙달지향 성취목표형 집단에 속할 확률이 낮았다. 또한 2차 시기 대인관계 공격성이 높을수록 평균 성취목표형 집단보다 고사회적 성취목표형 집단에 속할 확률이 높았다.

Purpose: The purpose of this study was to examine the prevalence and risk factors of suicidal ideation among middle class Korean. Methods: Cross sectional study was designed for secondary data analysis. From the 8th Korea Health Panel survey (2008~2013), a total of 6,037 data was drawn and analyzed by developmental stage using descriptive statistics including frequency, percentage, $x^2$ test, and logistic regression analysis. Results: Across all age groups, high physical-mental stress, frustration, anxiety about the future and low self-perceived health status or social class were found to be the risk factors of suicidal ideation. Peer-compared subjective health status and frustration significantly influenced the adolescents. The young adults'suicidal ideation was mainly influenced by physical and mental stress, frustration and absence of economic activity. For the middle-aged, physical and mental stress, frustration, future anxiety, low peer-compared subjective health status were found to be the major influencing factors. The predominant risk factors for the elderly were frustration and low peer-compared subjective health status. Conclusion: Making comparisons to others significantly influence suicidal ideation throughout all life cycles. Improvement of mental health and suicide prevention can be enhanced by avoiding negative comparison to others.

This study conducted descriptive literature review on adolescent smoking and the related factors to realize significance of adolescent smoking onset in Korea and to identify risk factors of smoking incidence. Korean adolescent smoking status was generated based on the cumulated data of the Korean Association of Smoking and Health. Risk factors of adolescent smoking were identified based on 18 studies written in English, with cross-sectional research design and published as a peer-reviewed journal article between 1994 and 2003. The results were as follows. 1. Korean adolescent smoking rate was the highest among OECD affiliated countries; in particular, male adolescent smoking incidence was very serious. 2. Risk factors related to smoking of adolescent population were personal factor, friend factor, family factor, and mass-media factor. Demographic characteristics, attitudes on smoking, and willingness of smoking, and health behaviors were selected as personal factor of smoking. 3. Best friends smoking was a strong factor of students' smoking set. Prevalent popularity of smoking in peer-group allowed students to feel free to smoking. 4. Concerning family factor related to smoking status, parents' smoking and sibling's smoking were significant indicators of adolescent smoking status. 5. Seeing smoking behaviors and scenes through films, TV shows, drama, and advertisement was a significant risk factor of adolescent smoking status.

Purpose: The purpose of this study was to examine the relationship between social support (family, healthcare provider, friends/peer), treatment belief, hope, and health status in patients on hemodialysis, and to identify direct and indirect effects of the variables on patients' health status. Methods: The self-regulation model was used to establish a path model. Data were collected from 240 patients. Multidimensional Scale of Perceived Social Support, Revised Illness Perception Questionnaire, Herth Hope Index, and Medical Outcomes Study Short Form-12 were used. Data were analyzed using the SPSS and AMOS programs. Results: The model was supported by fit statistics ($x^2=3.33$, p=.343, GFI .995, RMSEA .021, AGFI .968, NFI .986, CFI .999, TLI .993). Family and friends/peer support showed a significant direct influence on hope, while healthcare provider support directly influenced treatment belief. Social support, treatment belief, and hope directly and indirectly influenced health status, explaining 28.7% of the variance. Conclusion: These results show mechanisms underlying connections between social support and health status by demonstrating impact of social support and showing treatment belief and hope as mediators between social context and outcomes. To promote health of patients on hemodialysis, it is necessary for patient, family, healthcare professional, and friends to collaborate.

Background: To identify the prevalence of different stages of smoking and differences in associated risk factors. Materials and Methods: Thos longitudinal study started in February 2011 and the subjects were 2552 form one students aged between twelve to thirteen years of from 15 government secondary schools of Kinta, Perak. Data on demographic, parental, school and peer factors were collected using a self-administered questionnaire. We examined the effects of peer, school and parental factors on the five stages of smoking; never smokers, susceptible never smokers, experimenters, current smokers and ex-smokers, at baseline. Results: In the sample, 19.3% were susceptible never smokers, 5.5% were current smokers 6% were experimenters and 3.1% were ex-smokers. Gender, ethnicity, best friends' smoking status, high peer pressure, higher number of relatives who smoked and parental monitoring were found to be associated with smoking stages. Presence of parent-teen conflict was only associated with susceptible never smokers and experimenters whereas absence of home discussion on smoking hazards was associated with susceptible never smokers and current smokers. Conclusions: We identified variations in the factors associated with the different stages of smoking. Our results highlight that anti-smoking strategies should be tailored according to the different smoking stages.
