Children in their early 10s tend to be very conscious about their own images and how they look to others in the face of puberty. This study was conductedwith fifth and six graders to investigate the effect of urges to change their hairstyle on attempts for hairstyles and to provide basic information needed to provide effective hair styling services to early teens. The subjects were recruited from male and female fifth and six graders at the M Elementary School located in Gyeonggi-do. Data were collected from October 20 to October 31, 2014 via a questionnaire. A total of 200 questionnairrs were distributed, and 173 completed questionnaires were analyzed in this study, excluding 27 questionnaires due to insufficient answers. Statistical analysis was performed using SPSS 21.0. The results of this study are as follows: in the questions asking subjects' preference for hairstyles, subjects' satisfaction level on their hairstyle, particularly their current hair style, was the highest. Thus, they changed their hair style in favor of fresh look. This means that subjects had greater desire to follow trendy hairstyles when they tried harder to be fashionable and to change their mood and reduce stress. The results of the study showed that subjects tended to put more value on their physical appearance when they had stronger desire to keep their hairstyle neat and clean.

조직공정성이 사회복지사의 조직시민행동에 미치는 영향에 관한 연구 : 상사신뢰의 매개효과를 중심으로

최소연(Choi So-Yeun) 한국사회복지학회 2005 한국사회복지학 Vol.57 No.3

사회복지사의 자발적 초역할 행동인 조직시민행동(OCB)은 클라이언트에 대한 질적 서비스와 사회복지조직성과에 매우 중요하다. 이러한 중요성을 반영하여 본 연구는 절차공정성, 분배공정성, 상사신뢰가 조직시민행동에 미치는 영향을 파악하여 실효성 있는 조직관리의 함의를 도출하고자 하였다. 이를 위해 사회복지사(360명)의 자기보고응답자료와 상사(59명)가 측정한 조직시민행동의 paired data를 활용하여 실증연구를 진행하므로 선행변수가 조직시민행동에 미치는 직간접영향을 구조방정모형을 통해 검증하였다. 연구결과 절차, 분배공정성은 조직시민행동에 영향을 미치지 않았으나, 상사신뢰를 통해 간접영향을 미치는 것으로 확인되었고 분배공정성에 비해 절차공정성의 영향이 보다 큰 것으로 나타났다. 연구결과를 토대로 사회복지사의 자발적 행동에 대한 관리는 파편적 현상에 대한 개입이 아니라 조직관리에 대한 성원의 인지와 그로 인해 야기되는 태도 그리고 행동이라는 조직생활의 연속선상에서 포괄적으로 관리되어야 한다는 것을 제시하였다. The OCB(organizational citizenship behavior), spontaneous extra-role behavior of social workers, plays very important role in the provision of qualitative service for the clients and the organizational performance of social welfare agencies. Starting from the importance of OCB for the effective organizational management, this study focuses on the effects of antecedents such as organizational justice(procedural and distributional) and trust in supervisor on the OCB. This study collected data from 360 social workers and 59 their supervisors working in the community welfare centers, paired the self-reported data and the supervisor-rated data, and analyzed the data through the SEM (Structural Equation Modeling) method. The findings of the study show that organizational justice(procedural and distributional) has no direct effect on the OCB, but indirect effect on the OCB through the mediator of trust in supervisor, and that procedural justice has more effect than distributional justice. This study suggests that the management of spontaneous behavior of social workers is not a separated fragmentary phenomenon but should be understood and managed comprehensively in the continuation of the perception of organizational members for the organizational management, the resulting affectivity toward their supervisor, and their behavior in the organizational life.

Objectives:This study was conducted to investigate various social and environmental factors related to children’s sleep and to know how these factors may affect sleep duration and patterns. Methods:Total 2,958 students of three elementary school in Daegu, Korea were enrolled in this study. We investigated various factors related to children’s sleep using Sleep questionnaires for Korean Children(SKC) for two days. The factors that we investigated were classified into sleep-related factors, daily life factors, environmental factors. We also evaluated correlations between these factors and children’s sleep duration. Results:When identifying various factors related to children’s sleep in three elementary school groups, group A showed significantly later bedtime(F=103.683, p<.001), longer sleep latency(F=6.30, p<.05), shorter total sleep duration(F=5.93, p<.05), and shorter nap duration(F=141.94, p<.001) compared to other group B and C. Also, group A showed significantly earlier time of returning home(F=71.073, p<.001), shorter amount of TV viewing (F=108.45, p<.001), earlier time of stopping TV viewing(F=24.01, p<.001), shorter amount of computer use(F=67.10, p<.001), earlier time of attending school(F=5.40, p<.05), longer hours in private institute(F=15.57, p<.001), smaller number of family(F=11.00, p<.001), longer father’s years of education(F=311.82, p<.001), and longer mother’s years of education(F=334.87, p<.001) compared to other two groups. Conclusion:Group A was associated with late bedtime, long sleep latency, short total sleep duration despite relatively short nap duration, short amount of TV viewing, short amount of computer use, early time of stopping TV viewing, small number of family, long mother’s years of education. This result suggests that total amount of hours in private institute and parents’ academic demands might be a contributing factor for children’s sleep duration.

Objectives:We conducted this study to investigate the relationship between sleep duration and body mass index (BMI), in Korean children. Methods:We performed a cross-sectional analysis of data collected on 3,639 boys and girls (aged 7-12) in Daegu, Korea. The data included each child’s age, sex, weight, height, extracurricular activities, bedtime, wake-up time, sleep latency, total sleep duration, parents’ occupations, and parents’ educational levels. The relationship between sleep duration and each variable was examined via analysis of variance (ANOVA). Results:The analysis showed an association between short sleep duration and high BMI. Boys showed a graded inverse relationship between sleep duration and BMI. However, there was no significant corresponding result for girls. In the total sample, hours of computer use, time when the computer was turned off, time when the television was turned off, mother’s bedtime, and hours of extracurricular activity were associated with longer sleep duration. No association was found between sleep duration and hours of watching television, child’s wake-up time, or educational level of the parents. Conclusion:The results of this study show an inverse relationship between a child’s sleep duration and BMI;thus, children with shorter sleep duration tend to have higher BMIs.

In this paper, we present a adaptive fuzzy neural network controller which unifies both fuzzy logic and multi layered feedforward neural networks. In the proposed adaptive fuzzy neural network controller, the parameters of membership functions in the antecedent part of fuzzy inference rules are identified by using the error backpropagation algorithm as a learning rule, while the coefficients of the linear combination of input variables in the consequent part are determined by using the least squared estimation method. Finally, the effectiveness of the proposed controller is verified through computer simulation of a container crane system.

PURPOSE. The purpose of this study was to determine fracture resistance and failure modes of three-unit fixed dental prostheses (FDPs) made of lithium disilicate pressed on zirconia (LZ), monolithic lithium disilicate (ML), and monolithic zirconia (MZ). MATERIALS AND METHODS. Co-Cr alloy three-unit metal FDPs model with maxillary first premolar and first molar abutments was fabricated. Three different FDPs groups, LZ, ML, and MZ, were prepared (n = 5 per group). The three-unit FDPs designs were identical for all specimens and cemented with resin cement on the prepared metal model. The region of pontic in FDPs was given 50,000 times of cyclic preloading at 2 Hz via dental chewing simulator and received a static load until fracture with universal testing machine fixed at $10^{\circ}$. The fracture resistance and mode of failure were recorded. Statistical analyses were performed using the Kruskal-Wallis test and Mann-Whitney U test with Bonferroni's correction (${\alpha}=0.05/3=0.017$). RESULTS. A significant difference in fracture resistance was found between LZ ($4943.87{\pm}1243.70N$) and ML ($2872.61{\pm}658.78N$) groups, as well as between ML and MZ ($4948.02{\pm}974.51N$) groups (P<.05), but no significant difference was found between LZ and MZ groups (P>.05). With regard to fracture pattern, there were three cases of veneer chipping and two interfacial fractures in LZ group, and complete fracture was observed in all the specimens of ML and MZ groups. CONCLUSION. Compared to monolithic lithium disilicate FDPs, monolithic zirconia FDPs and lithium disilicate glass ceramics pressed on zirconia-based FDPs showed superior fracture resistance while they manifested comparable fracture resistances.

본 연구는 사회복지기관의 현상분석을 통해 조직의 성과를 지향하기 위한 조직의 내적환경은 무엇인지를 파악하는데 목적을 두고 있다. 기관의 현상분석을 위해 서울의 B지역사회복지관의 기관문서검토, 관찰 그리고 직원을 대상으로 설문조사를 행하였다. 자료검토와 관찰을 통해 얻어진 내용들은 조직관련 이론을 근거하여 조직의 강점과 약점, 위기와 기회의 측면(SWOT)에서 분석을 시도하였으며, 설문조사를 통해서는 조직성원에 대한 기본적인 사항, 성원들이 인지하고 있는 기관에 대한 제반 만족수준의 정도 그리고 조직성과에 있어 중요한 변수로 고려되고 있는 헌신에 영향을 미치는 조직의 요인들을 파악하였다. 관찰결과 직원개발과 지식공유를 위한 조직차원에서의 노력이 강점으로 파악 된 반면, 조직구조의 중앙화로 성원들의 의사참여 기회가 적은 것을 알 수 있었다. 설문조사결과 직원들의 조직에 대한 만족수준은 전반적으로 높게 나타났으며, 사명인식정도, 의사참여기회, 의견반영정도, 교육기회 제공정도, 업무의 적합성 등이 헌신과 상관관계가 있는 것으로 나타났다. 헌신과 상관관계가 있는 변수의 영향력을 보기 위해 회귀분석을 실시한 결과 직원들의 사명에 대한 인식정도, 업무의 적합성 그리고 직원들이 인지한 능력개발정도가 헌신에 영향을 미치는 것으로 나타났다. 연구결과를 토대로 성과지향적인 조직환경구성을 위해 팀체제로 조직의 구조를 재배치 하였으며, human resource management의 중요성과 직원들의 욕구에 대해 기관관리자가 민감해야 할 필요성을 제언하였다. The major purpose of this study is to identify internal organizational environments affecting organizational performance through the diagnosis of community welfare organizations. This study relies upon document review, observations and survey research methods in the Seoul B community welfare center. From the data collected by document review and observations, this study conducts SWOT analysis of organizational strength, weakness, opportunity and threat, focusing on the organizational theories. From the survey research of organizational members, this study analyzes the organizational members' perceived level of satisfaction and the significant factors affecting organizational commitment that is now considered as an important factor for the organizational performance. The findings of observation show that personnel development and organizational support of knowledge co-ownership are major strengths of the organization and that organizational members have limited opportunity for the participation in the decision making because of the centralization of organizational structure. The analysis of survey research suggests that organizational members' level of satisfaction toward the organization is relatively high and that organizational members' acknowledgement of mission, appropriateness of work, and organizational members' perceived development of capability are major factors affecting organizational commitment. This study concludes that structuring performance-based organizational environments depends on the maximization of opportunity for the participation in the decision making, the redesign of organizational structure focusing on the functions of work, the development of human resource management, and the organizational managers' ability to satisfy the needs of internal organizational members.
