Objective: This study aimed to investigate the factors associated with masticatory performance, as measured with a chewing gum containing spherical resinous microparticles, and to evaluate the method by examining the relationship with self-reported masticatory status. Methods: The participants in this study comprised 903 industrial workers (mean age, $42.2{\pm}11.6years$). A questionnaire was administered to assess self-reported masticatory status. The masticatory performance score was calculated by counting the number of particles in the chewing gum. Clinical oral examinations were administered. Multiple linear regression analysis was conducted on the masticatory performance scores to examine the related factors. Analysis of covariance was conducted to investigate the association between the masticatory performance score and the self-reported masticatory status. Results: Significant predictors of the masticatory performance score were sex (p<0.001), age (p<0.001), decayed teeth (p=0.009), total-functional tooth units (p<0.001), periodontitis (p=0.003), and malocclusion (p=0.011). The relationship between the masticatory performance score and the self-reported masticatory status was attenuated after controlling for confounding factors. Conclusion: The masticatory performance increased with age and decreased as the oral health status worsened. Using this chewing gum method partly, but not comprehensively, reflects masticatory performance. Therefore, various masticatory performance-related indexes should be employed to measure masticatory performance accurately.

Purpose: The purpose of this study was to explore the barriers and the enhancing factors and predictors to postpartum care performance. Methods: The Research design in this study was a cross-sectional correlational survey. Subjects were 145 women at 6 to 10 weeks post delivery at an OB & GY clinic. Data was gathered with postpartum care performance, and other related variables including emotional status during pregnancy, fatigue, health recovery status, maternal role and identity. Data was analyzed using the SPSS WIN(version 11.0) program. Results: The mean score of postpartum care performance was 3.08 of 5, it had significant differences in emotional status during pregnancy, coincidence of expected sex, health recovery status, postpartum fatigue and postpartum depression. The maternal role and health recovery status were enhancing factors of postpartum care performance. Also, the barrier factors were fatigue, depression and coincidence of expected sex. Among these factors, the present health recovery status had an predictability of 11.7%, postpartum fatigue 3.2%, and coincidence of expected sex 2.5%, for a total predictability factor of 17.4% on postpartum care performance. Conclusion: Among these related factors to postpartum care performance, present health recovery status was the most predictable factor and then postpartum fatigue, and coincidence of expected sex. We need to establish a strategy to reduce postpartum fatigue and implement nursing interventions for health related consequences in postpartum women.

Purpose: The purpose of this longitudinal study was to examine the relationship between postpartum care performance and postpartum health status. Sample: The study subjects were 82 mothers who delivered full-term infants at 3 hospitals at P city. Data were collected for their health status at the postpartum unit and the sample was followed up to 6 weeks postpartum to collect postpartum care performance and health status. Results: Mothers rated postpartum care performance as moderate to high and especially rated the maternal role attainment the highest. Mothers experienced 4 physical symptoms and moderate levels of fatigue. In addition, they experienced moderate levels of positive affect and low levels of negative affect at both times. Canonical correlation revealed that ostpartum care performance was related to postpartum health status with 2 significant canonical variables. The first variate indicated that mothers who performed hospitality, physical and emotional recovery, self-caring, and role attainment well showed higher positive affects, lower negative affects, fewer physical symptoms, and lower levels of fatigue. The second variate showed that the greater the performance of caring and physical and emotional recovery, the fewer physical symptoms and lower levels of fatigue. Conclusion: Although Korean traditional postpartum care performance was related to postpartum health status, the further study is needed to identify the causal relationship between them. Nurses need to integrate the perspective of westernized postpartum care and Korean traditional views of postpartum approach to maintain and promote women's health.

최신 고성능 컴퓨팅 시스템에서는, 대용량 병렬 연산을 효과적으로 처리할 수 있는 GPU의 우수한 연산 성능을 그래픽 처리 이외의 범용 작업에 활용하는 GPGPU 기술에 관한 연구가 활발하게 진행 중이다. 하지만 범용 응용프로그램의 특성이 GPU 구조에 최적화되어 있지 않기 때문에 범용 프로그램 수행 시 GPGPU는 GPU의 연산 자원을 효과적으로 활용하지 못하고 있다. 그러므로 본 논문에서는 GPGPU 기술을 사용하는 컴퓨팅 시스템의 성능을 보다 향상시킬 수 있는 GPU 연구에 대한 방향을 제시하고자 한다. 이를 위하여, 본 논문에서는 GPU 성능 저하 원인 분석을 수행한다. GPU 성능 저하 원인을 보다 명확하게 분류하고자 본 논문에서는 GPU 코어의 상태를 완전 활성화 상태, 불완전 활성화 상태, 유휴 상태, 메모리스톨 상태, 그리고 GPU 코어 스톨 상태 등 5가지로 정의하였다. 완전 활성화 상태를 제외한 모든 GPU 코어 상태들은 컴퓨팅 시스템의 성능 저하를 유발한다. 본 논문에서 성능 저하 원인을 찾고자 벤치마크 프로그램의 특성에 따라 각 GPU 코어 상태의 비율 변화를 측정하였다. 분석 결과에 따르면, 불완전 활성화 상태, 유휴 상태, 메모리 스톨 상태 그리고 GPU 코어 스톨 상태는 연산 자원 활용률 저하, 낮은 프로그램 병렬성, 높은 메모리 요청, 그리고 구조적 해저드에 의해 각각 유발된다.

The purposes of this study were to show general trends in the aspects of psychological family environment (parental communication), peer factor, academic performance factor, depression perceived by adolescents and to examine possible changes in such trends in accordance with demographic variables and the family structure environment (parental marital status, family economic status, and parents' education level), and then to determine the effect of these variables on adolescents' depression. The subjects were 1009 middle and high school students in Seoul and Gyeonggi province. The main results were as follows: 1) Paternal communication was significantly lower in technical high school students, divorced/ separated parents, and families of lower economic status. Maternal communication was significantly lower in male students, divorced/sepa-rated parents, and families of lower economic status. Academic performance problems was significantly higher in males, technical high school students, divorced/ separated parents, families of lower economic status, and a less educated father. Peer relations was significantly lower in students of divorced / separated parents, and of families of lower economic status. Depression was significantly higher in technical high school students, divorced / separated parents, and families of lower economic status. 2) In the case of male students, paternal communication had both a direct and an indirect negative effect through peer relations on depression, while academic performance problems had both a direct and an indirect positive effect through peer relations on depression. Both peer relations and maternal communication had a positive and a negative direct effect on depression. School grade had both a direct and an indirect negative effect through paternal communication on depression. Parental marital status(divorced or separated) had both a direct and an indirect positive effect through academic performance problems on depression. Family economic status had only an indirect effect on discussed.
