  • In bicycle design, saddle is the major part which effects the subjective comfort of rider. This study examines the correlation between the subjective comfort and elastic body pressure. The elastic body pressure measuring instrument for free-form surface such as saddle is developed by force sensor register, A/D converter and computer. The subjective comfort is measured quantit- atively by 11-point scale method and the elastic body pressure distribution is obtained through 3 different saddles at 4 postures. The pressure distribution is presented by computerized equi- pressure contour. While mean pressure, standard deviation of pressure, maximum pressure are inversely proportional to subjective comfort, the modified saddle-bearing weight which is the surface integral of pressure is directly proportional. Consequently, standard deviation of pressure is most important characteristic which affects variation of subjective comfort.

  • 본 연구의 목적은 주관적 사회적 지위가 일의 의미에 미치는 영향을 알아보는 것이다. 주관적 사회적 지위를 한 개인이나 조직이 갖는 존경과 영향력으로 정의하고, 조직 내 개인의 주관적 사회적 지위가 높을수록 일의 의미를 높게 지각할 것이라고 예상하였다. 또, 조직 내 개인의 주관적 사회적 지위는 개인이 속한 직종의 주관적 사회적 지위보다 일의 의미 향상에 더 큰 영향을 줄 것이라고 예측하였고 두 개의 실험을 통해서 이를 검증하고자 하였다. 실험 1에서 미국 직장인을 대상으로 조직 내 개인의 주관적 사회적 지위와 직종의 주관적 사회적 지위가 일의 의미에 미치는 영향을 파악하였다. 실험 2에서는 한국 직장인을 대상으로 해당 가설을 반복 검증하고, 조직 내 객관적 사회적 지위인 계급에 따라 조직 내 주관적 사회적 지위가 일의 의미에 미치는 영향이 다를 것이라는 가설을 확인하고자 하였다. 연구 결과, 한국과 미국 직장인 모두 조직 내 개인의 주관적 사회적 지위가 높을수록 일의 의미를 높게 인식했다. 또, 조직 내 개인의 주관적 사회적 지위는 직종의 주관적 사회적 지위보다 일의 의미에 더 큰 영향을 주는 것으로 나타났다(실험 1). 실험 2에서 객관적 사회적 지위인 계급에 따라 조직 내 개인의 주관적 사회적 지위가 일의 의미에 미치는 영향이 다른 것으로 나타났는데, 객관적 사회적 지위가 낮은 경우에는 개인이 조직 내에서 존경을 받고 영향력이 있다고 생각할수록 일의 의미가 향상되었지만, 객관적 사회적 지위가 높은 경우에는 조직 내 주관적 사회적 지위가 일의 의미에 미치는 영향이 유의하지 않은 것으로 나타났다. 이러한 연구 결과를 바탕으로 본 연구의 학문적 의의, 한계와 미래 연구 방향을 논의하였다.

  • Korean adolescents have a lower subjective well-being compared to their counterparts in other Organization for Economic Co-operation and Development member countries as well as experience more psychological difficulties than adults. Previous research shows that parenting behavior has a considerable influence on adolescent subjective well-being. Additionally, the personality dimension of self-directedness, the ability to regulate personal behavior to obtain onindividual goals, has a positive influence on subjective well-being. This study analyzed the structural relationship between parenting behavior, self-directedness, and the subjective well-being of Korean adolescents as well as investigated the mediating effect of self-directedness in the relationships between parenting behaviors and the subjective well-being of adolescents. Participants were 325 middle school students in Gwangju, Korea, who completed measures of self-directedness (from the Korean Junior Temperament and Character Inventory), subjective well-being (Well-Being Scale of Adolescents in Korea), and perceived parenting behaviors (My Memories of Upbringing - Short Korean version). Results showed that emotional warmth had a statistically significant direct impact on adolescents' subjective well-being. However, the findings also indicated a statistically significant indirect impact mediated by self-directedness. Rejection and overprotection had a statistically significant indirect effect on adolescents' subjective well-being that was mediated by self-directedness. The results provide information that can be used to develop programs to improve the subjective well-being of adolescents as well as confirm the importance of parenting behavior and self-directedness during adolescence.

  • The study examined how the personality traits, manifested during serious leisure experience, i.e., experiences that involve the acquisition of special knowledge or techniques and the participation required to achieve the expertise necessary to express them. This study also investigated how such subjective well-being affected behavioral intention, specifically, the intention to use the same leisure facilities again and to spread this information to acquaintances by positive word of mouth. A survey was administered to 727 research subjects selected from pre-registered panels enrolled by an online research organization. The main constructs examined in this study were measured on 5-point Likert scales using multiple items. A structural equation model was employed to verify the proposed conceptual model and the relationships among variables. The results revealed that, of the personality traits, participants high in extraversion, openness to experience, and agreeableness felt high levels of life satisfaction and positive affect, i.e. a sense of subjective well-being. Second, users who felt a high level of subjective well-being, specifically, high life satisfaction and positive affect, also indicated a high level of behavioral intention. Finally, the academic and practical implications and limitations of the study, as well as future research plans involving the personality traits underlying serious leisure experiences are discussed.

  • Objective: This study aimed to compare the subjective health status, physical activity index, and perceived stress rate of obese children with those of healthy children through propensity matching analysis and to use the results to help manage obese children. Design: Descriptive correlation study. Methods: This study conducted a secondary analysis using raw data from the National Health and Nutrition Examination Survey. Propensity matching (1:2) was conducted between obese and healthy adolescents. Results: The number of days of physical activity was 1.22 days for the obese adolescent group and 1.01 days for the non-obese adolescent group, which was higher in the obese group (p=0.003). The subjective health status was 3.43 and 3.81 in the obese and non-obese adolescent groups, respectively, showing a higher difference in the normal group (p<0.001). No statistical difference was observed in the perceived stress rate (p=0.871) or strength exercises (p=0.190) between the two groups. Conclusion: This study suggests the need for development measures to effectively improve youth physical activity, muscle-strengthening programs, stress management, and subjective health status in obese and normal groups.
