This paper addresses the issue of workflow on Grid and P2P, and proposes a layered workflow architecture and its related workflow models that are used for not only distributing workflows' information onto Grid or P2P resources but also scheduling the enactment of workflows. Especially, the most critical rationale of this paper is on the fact that the nature of Grid computing environment is fitted very well into building a platform for the maximally parallel and very large scale workflows that are frequently found in very large scale enterprises. The layered architecture proposed in this paper, which we call Enterprise Workflow Grid Architecture, is targeting on maximizing the usability of computing facilities in the enterprise as well as the scalability of its underlined workflow management system in coping with massively parallel and very large scale workflow applications.

Objectives: The purpose of this study was to assess predictors of health-related quality of life (HRQoL) in elderly Asian American and non-Hispanic White cancer survivors. Methods: We conducted cross-sectional secondary data analyses using the combined datasets from the Surveillance, Epidemiology, and End Results program and the Medicare Health Outcomes Survey. Results: Elderly Asian American cancer survivors reported a lower mental HRQoL but a comparable physical HRQoL relative to elderly non-Hispanic White cancer survivors. Stress factors, such as comorbidities, difficulties with activities of daily living, and a history of depressive symptoms, along with coping resources like self-rated health and the ability to take the survey in English, were significantly associated with mental and physical HRQoL. Among elderly Asian American cancer survivors, a significantly lower mental HRQoL was observed among those taking the survey in the Chinese language. Conclusions: The findings suggest that race exerts a differential impact on HRQoL. Interventions should be designed to address the distinct cultural, linguistic, and systemic needs of elderly Asian American cancer survivors. Such an approach could assist in reducing cancer-related health disparities.

The purpose of this study was to investigate the effects of life stress, depression, and drinking motives on problem drinking among college students. The subjects were 249 college students and data were collected through a self-reported structured questionnaire from Nov to Dec 2016. Collected data were analyzed by descriptive statistics, ANOVA, Pearson's correlation, and stepwise multiple regression. The findings showed that drinking motives were the biggest factor influencing their problem drinking with coping, social, enhancement and conformity motives exerting special effects on it. As for correlations with problem drinking, interpersonal and ongoing task stress of life stress had positive correlations with problem drinking. Coping, social, enhancement, and conformity motives also had positive relations with problem drinking. Drinking motives had critical effects on the problem drinking of college students with coping, social, and enhancement motives strongly impacting on it. The findings necessitate examining the drinking motives of college students to make them choose to drink including negative emotions, social activities, and gatherings in order to prevent their problem drinking. These factors could explain 33% of the problem drinking. It is also required to develop methods for them to utilize resources other than drinking and run drinking education and temperance programs at the school level.

Background: It is estimated that about 13 million artisanal and small-scale miners carry out their activities under harsh, precarious, unfriendly, and risky conditions. Yet, our understanding of the extent to which these workers use personal protective equipment (PPE) and navigate through the various risks and hazards they face is still limited. This article has two main objectives. First, it explores the extent of usage of PPE among artisanal and small-scale miners for the prevention of hazards and risks. Second, it examines the coping strategies used by these miners as a response to experiences of occupational injuries and risks Methods: A cross-sectional survey of small-scale miners was conducted in six communities across three districts in Ghana, West Africa. The mixed methods approach was adopted. A total of 148 small-scale miners participated in the study. Six focus group discussions (FGDs) were held across the six communities. The data were analysed using descriptive statistics. Chi-square tests were used to analyse the relationship between some socio-demographic characteristics (sex, age, and educational background) and the usage of PPE. Open-ended questions and responses from FGDs were analysed based on the content and verbatim quotations from miners. Results: Findings suggest that 78% of the miners interviewed do not use the appropriate PPE citing reasons such as cost, and their personal discomfort associated with use of PPE. There was no significant relationship between socio-demographic characteristics (i.e., sex, age, education and major mining activity) and the usage of PPE. The study further revealed four main coping strategies used by miners to handle the risks. These are rest, taking unprescribed medication and hard drugs, registration with health insurance scheme and savings and investments. Conclusion: This study shows that very few artisanal miners use PPE despite the significant hazards and risks to which they are exposed. The study recommends to the government to put in place measures to ensure that miners adhere to health and safety regulations before undertaking mining activities. This means that health and safety plans and use of PPE should be linked to the license acquisition process for miners.

This study was conducted to investigate actual conditions and needs on breastfeeding education for pregnant women in health centers for the development of a breastfeeding educational program. The questionnaires were mailed to 245 health centers and 148 (60.4%) questionnaires were returned. 91% of the health centers had breastfeeding education for pregnant women. 66% of them operated breastfeeding education as one part of other health programs. About 76% of supervisors and 64% of educators were the nurses. The teaching methods frequently used were lectures (30.5%), giving out booklets and leaflets (22.6%), demonstration and practice (21.5%), personal counseling (13.3%), and others. The teaching materials used were materials of outside speakers (39.7%), materials of development oneself (19.0%), materials of academic association or institute (14.8%), and others. The subjects which educators taught were the benefits of breastfeeding (16.7%), breastfeeding techniques (15.8%), caring for breasts before and after delivery (15.1%), nutritional management for lactating women (14.2%), coping strategies for the difficult situation of breastfeeding (13.3%), and others. Those were different from each other according to the educators' general characteristics. Success factors of education were increased motivation for breastfeeding (52.8%), practice (22.6%), professional's lecture (11.3%) and others. The failure factors of education were the ineffectiveness of the lecture method (69.2%), lack of education for supporters (15.4%) and lack of standardized education (15.4%). The most important barrier of education was the lack of a standardized breastfeeding educational programs (43.9%). The most effective teaching methods that educators thought were demonstration and practice (24.0%). The educators thought they need the tools and space for practice (28.2%), a standardized breastfeeding educational program (26.9%), and the human resources (24.4%) for effective education. Subjects that educators thought important for education were the breastfeeding techniques, benefits of breastfeeding, caring for breasts before and after delivery, nutritional management for lactating women, coping strategies for the difficult situation of breastfeeding, rooming system after delivery, ways to assess mother's milk quantity, introducing successful cases of breastfeeding in rank order. To promote the effectiveness of breastfeeding education, standardized breastfeeding educational programs, diverse teaching materials, space and tools, and human resources are needed.

This study aimed to examine the direct impact and pathways of stress factors, internal resources(positive self-esteem and negative self-esteem) on the depressive symptoms based on stress coping theory, grouping older stage into three groups such as, the young-old, the old- old, oldest-old. This study further examined the mediating role of self-esteem in the relationships between stress factors and depressive symptoms. Data from 1st year Korea Welfare Panel Study were used for the analysis. The total number of participants was 4,338 who were over 65. Data are Analyzed using Structural Equation Modeling. Results revealed that stress factors and internal resources(positive self-esteem and negative self-esteem) directly affected depressive symptoms. The effects of stress factors on depressive symptoms were mediated by positive and negative self-esteem.. Results of multi-group structural equation modeling showed that the effects and pathways of stress factors and self-esteem on depressive symptoms were different into the three old groups. Based on the findings, the implications for policy and practice were discussed.

This study developed the Climate Variability Index (CVI) to assess the water resources through adding detail indicators into the existing regional Water Poverty Index (WPI) to consider climate variability and flood damage. This study aims at selecting indicators of WPI focused on water availability and regional climate variability, assessing regional variability of the indices during 1998-2007, and providing information to help determining the priority of water sector policies, investment, and applications. The WPI represents the relationship between the level of welfare and the water use. Considered with flood management and climate variability, CVI added by regional characteristics may be used in water resources management as well as flood mitigation for coping with climate change.

기후변화 대응은 온실가스 배출의 감축 및 흡수원을 확대하는 완화(mitigation)와 기후변화로 인한 영향과 취약성을 평가하여 피해를 최소화하는 적응(adaptation)이 상호 균형을 이루어야 한다. 지금까지 우리나라를 포함한 국제사회는 대부분 완화를 위해 노력해 왔지만 최근에 들어 완화만으로는 기후변화의 영향을 회피하기 어렵다는 사실이 인식되면서 적응 연구가 다양하게 이루어지고 있다. 이러한 상황 가운데 적응 계획의 실현화를 위해서 기후변화의 불확실성을 고려한 의사 결정에 관한 연구가 반드시 뒷받침 되어야 한다. 기존의 일반적인 의사결정은 다양한 미래 시나리오들 하에 가장 높은 효용을 가져오는 최적(Optimal)의 대안을 채택하는 고전적 결정분석(Classical Decision Analysis)의 프레임을 사용하였다. 그러나 기후변화로 인해 미래 기후 예측 시나리오의 불확실성이 증대되면서 최근에는 최적의 대안을 선정하는 것에 대한 의문이 제기되며 새로운 기법에 대한 연구가 이루어지고 있다. 본 연구는 기후변화의 불확실성을 고려하기 위한 새로운 의사결정 기법인 로버스트 의사결정(Robust Decision Making, RDM)을 실제유역의 적용을 통해 제안하고자 한다. 로버스트 의사결정은 RAND에서 개발한 것으로 최적의 대안을 채택하는 것 대신 모든 가능한 시나리오 가운데 가장 안정적인 전략을 채택한다는 것에서 기존의 의사결정 체계와 차이가 있다. 연구의 적용은 안동-임하댐 유역을 대상으로 온실 가스 배출 시나리오 A1B, A2, B1시나리오에 대해 15개의 GCMs에서 산출된 기후자료를 기반으로 기후변화의 시나리오를 작성하였으며, 다양한 측면의 대안을 설정하여 용수공급량을 평가하였다. 연구의 결과로 산정될 각 대안 별 안정적인 정도와 취약한 시나리오에 대한 정보는 기후변화의 불확실성을 전제한 의사결정을 할 때 로버스트 의사결정이 갖는 장점이 될 수 있다.
