This study is daily life research which aims to explore people's daily lives using a time dairy survey. The purpose of this study is to develop a typology of early, elderly over 55-year-olds using the 2009 Korean Time Use Survey. The results suggest that each man and woman can be classified according to three dimensions which are work time, housework time, and leisure time. Four groups of men are described: the work and leisure balanced type, the work-oriented type, the leisure-oriented type, and the leisure with housework type. Four groups of women are illustrated: the work-oriented type, the leisure-oriented type, the housework-oriented type, and the passive type. The eight groups are characterized by age, education, income, spouse, gender role, lack of time, and satisfaction of time use.

건설프로젝트는 일정한 기간 동안 주어진 목표를 수행하기 위한 작업들의 모임이라 정의할 수 있으며, 이를 위해서는 필요한 자원의 효율적 계획 및 관리가 필요하고, 이때 자원배당 및 자원평준화 기법이 활용된다. 하지만 자원제약이 있는 자원배당과 공기 제한이 있는 자원평준화 방법은 하나의 프로젝트에 개별적으로 적용되고 있어 전체 프로젝트의 공기와 효율적 자원이용 측면에서 적정화하기는 어렵다. 따라서 본 연구는 자원 평준화 방법의 Minimum Moment Algorithm 개념을 확대$\cdot$적용하여 적정 자원이용 및 공사기간을 산출하고자 한다. 이때 자원 활용의 상태를 나타내는 5가지 지표가 사용되며, 이들간의 중요도를 파악하기 위해 공정전문가를 대상으로 설문조사를 실시하였다. 마지막으로 가상 프로젝트의 적용을 통해 본 모형의 적용 가능성을 검증하고자 하였다.

The purposes of this study were to (1) examine the sub-dimensions of time management behaviors and satisfaction with time management, and (2) to identify the variables that can affect satisfaction with time management. Data was collected through an Internet survey answered by 611 working men and women. The data were analyzed using descriptive statistics, factor analysis, and multiple linear regression analysis. As a result of the study, the sub-dimensions of time management behaviour were extracted into three subordinate categories, which were, planning, human relation orientation, and urgency. The sub-dimensions of the satisfaction with time management were extracted into three subordinate categories, which were, satisfaction with the management results, satisfaction with time distribution, and satisfaction of spare time. Management result satisfaction displayed a positive relationship with planning and work time. The satisfaction with time distribution displayed a positively relationship with planning, relations-intention, the level of education, and sleeping time, while displaying a negative relationship with work time. Also, Women tended to be more satisfied with time distribution than men. Finally, the satisfaction of spare time was positively related with age, while negatively related to urgency and work time.

This study was conducted to investigate the effect of recipient activation time on the nuclear remodeling, chromatin structure, pronuclear formation and in vitro development of bovine nuclear transfer embryos derived from adult ear skin cells. Somatic cells were transferred to enucleated oocytes after quiescent treatments by serum starvation or culture to confluency. Nuclear transfer embryos were activated with a combination of Ca/sup 2+/-ionophore and cycloheximide at 1, 1.5, 2, 2.5, 3, and 5 h after electrofusion. (omitted)

The purpose of the present study was to investigate how 4-to 5-year-olds approach a competitive/cooperative task to obtain a resource. Sex and age differences were examined for the behavior and resource utilization of this task. The subjects were 74 same-age, mixed sex groups of 4 children each in three kindergartens in a large city. Each group of 4 children were classmates. The children were videotaped in a play situation where one child could view a cartoon movie (i. e. acquiring a resource) with the assistance of two children (one to turn the film tape and one to push the light-button), and the fourth child was a bystander. Time at each position and physical and verbal behavior constitute the data which were analyzed by ANOVA and ${\chi}^2$. The results of the time analysis showed that children cooperated quickly and were able to view the cartoon(resource utilization) for a large part of the session. High resource utilizers compared with low resource utilizers, exhibited more self-assertive and helping behaviors. Boys achieved more viewing time while girls were bystanders for a greater amount of time. Boys showed more physical and verbal behaviors during the task. Four-year-olds achieved less viewing time than 5-year-olds, indicating 4-year-olds were less effective in eliciting the help of their peers.

기계학습의 데이터 크기 및 컴퓨팅 부하 증가로 사물인터넷 시스템에서 에너지 효율적인 자원 플래닝이 중요해지고 있다. 본 논문에서는 사물인터넷 시스템의 실시간 워크로드 변화를 지원하는 자원 플래닝 정책을 제안한다. 이를 위해 본 논문은 실시간 태스크를 고정 태스크와 가변 태스크로 나누고 다양한 워크로드 상황에 대한 자원 플래닝 최적화를 수행한다. 이를 바탕으로 사물인터넷 시스템의 자원 설정을 고정 태스크 기반으로 시작한 후, 가변 태스크가 활성화될 경우 상황에 맞는 자원 플래닝을 즉시 적용할 수 있도록 한다. 시뮬레이션을 통해 제안한 정책이 사물인터넷 시스템의 프로세서 및 메모리 소모 에너지를 크게 줄일 수 있음을 보인다.

The purpose of this study is to examine the influence of parent-to-child financial transfers and economic resources on financial transfers, caregiving, and time donated from middle-aged adult children to their elderly parents. Analyzing data from the Wisconsin Longitudinal Study, which provides long-term observations of financial reciprocity and recent reports about elder care, the current study finds strong positive effects of prior parent-to-child financial transfers in the models of caregiving and time; which indicates the importance of reciprocity. In terms of determinants of resource transfers, the findings of logistic regression analyses suggest that the economic resources of parents and adult children are strong determinants of child-to-parent financial resource transfers. Sociodemographic characteristics of parents and respondents were observed as strong determinants of caregiving or time. In addition, caregiving responds more to the health and income levels of parents whereas donated time is responsive to the net worth of parents and parents' status. For adult children, gender is a strong determinant of both caregiving and time donation. The long-term health problem of adult children is a statistically significant predictor of caregiving, while the employment status of adult children and the number of siblings have statistically a significant association with time donated to care for the parents.

Time poverty is a kind of objective and subjective state which a person does not have a enough time to do his/her work or is in the mood to do something in a hurry. The major of family resources management has studied time as a resource to manage for long years. How to manage time has been a major part in education of family resources management. The education itself in nature has focused to inform knowledge and the disciplines of time management, to the students, on the other way, has a rare interest with a each student how to apply them or whether do in practical. Coaching is characterized as a practical learning and mutual communication skills with open questions, which help for a individual student to find his/her own goal related with time poverty or furthermore, whatever he/she wants to achieve in life. If the benefits of the education of family resources management as well as the benefits of practical learning of coaching could be merged in education on time management, the effectiveness of education to resolve time poverty is able to be increased. For the purpose, this study suggests a coaching approach in education of family resources management to resolve time poverty, by some comparisons of family resources management and coaching about time and time management.

최근 모바일 기기의 성능이 급격히 향상되고 다양한 앱이 등장하면서 대화형 작업뿐 아니라 실시간 작업을 동반하는 앱이 늘고 있다. 한편, 실시간 작업은 데드라인 제약 조건이 있어 종래의 시분할 시스템이 추구하던 자원 관리 정책으로는 실시간 제약 조건을 만족하는 데에 한계가 있다. 본 논문에서는 모바일 기기에서 대화형 작업과 실시간 작업이 동시에 실행될 때 CPU, 메모리, 스토리지로 이어지는 종단간 자원 관리를 어떻게 함으로써 실시간 작업의 제약 조건을 만족하면서 자원의 효율적인 관리가 가능한지에 대해 알아본다. 본 논문에서는 복잡한 자원관리 정책의 제안보다 각 자원들이 실시간 작업의 조건을 만족하기 위해 필요한 기본 개념에 대해 살펴보는 데에 초점을 맞춘다. CPU의 경우 실시간 작업을 위한 전담코어 할당, 메모리의 경우 워킹셋의 일정 비율을 보장하는 방식, 스토리지의 경우 고속 스토리지를 사용하고 문맥교환을 생략하는 방식 등 기본적인 지원 방안을 알아보고 이를 어떻게 효율화할 수 있는지에 대해 알아본다.

The common DNA extraction methods are indispensable for genotyping by molecular marker analysis. However, genotyping a large number of plants is painstaking. A modified 'NaOH-Tris' method used in this study reduces the extraction time while keeping the cost low and avoiding the use of hazardous chemicals. The endpoint analysis by realtime PCR tends to be fast and effective for the development of SNP markers linked to the 'Chunpoong' cultivar of Panax ginseng. The 'Chunpoong' marker was developed by a major latex-like protein gene sequence. From our results, we suggest that this method is successful in distinguishing 'Chunpoong' from a large number of ginseng cultivars.
