The objective of this study is to explore the situations and extension roles for rural elderly welfare program in North Dakota, USA. With a growing older population, aging has become an important issue for extension. Services for rural elderly available in North Dakota were adult day care, home health care, senior insurance counseling, nutrition and medication assistance programs, support groups, legal assistance, meals on wheels, nursing homes and more. With a growing older population, aging has become an important issue for extension. Extension provides programs and services for rural elderly. This study was conducted by literature review. First, many rural elderly Americans are actively engaged in volunteer work and have made substantial contributions to their communities. Second, extension educators from interdisciplinary areas should work together to develop programs. Extension programs can include intergenerational programs to help younger generations learn about the issue. Third, extension can collaborate with other agencies and groups to offer support groups. Offering educational programs is a key to empowering older people. Fourth, elderly residents may be the only increasing natural resource for volunteering in general, and for participation in community improvement in particular. Fifth, extension educators should be proactive in working with agencies to provide social access and in helping older people be actively engaged in their lives, especially in rural areas.

Purpose: This study tries to explore experiences with a special rating dementia service among family caregivers of elderly people with dementia. Methods: The participants were 11 family caregivers of elderly people with dementia and had used a day-care service from the special rating dementia service for more than 3 months. Data were collected through individual in-depth interviews and analyzed using content analysis. Results: Three categories emerged: "reminiscence of an entangled life", "feeling relieved from a stifled life", and "hope for a better life through help and support" with 8 sub-categories and 23 codes. By using the special rating dementia service, the participants experienced relief from the burden of caring for their elderly family member with dementia and restored their social relations or family relationships. They experienced a positive transition in which their caring for elderly family members with dementia was integrated into their daily lives, and they expressed their desires for better policies. Conclusion: These findings imply the importance and necessity of the special rating dementia service. Practical and systematic family support programs are necessary and proactive publicity activities by the government and public agencies are suggested to ensure that family caregivers can easily use the special rating dementia system.

This paper describes a web-based design review system as a knowledge management system relating reliability and safety system design. Since people's consciousness for safety and security become sensitive and increases the need of establishing a proactive prevention method for internal failures and relating risks in products. It also means that prevailing tacit knowledge in retired workers, in order to transform them to be easily used to support new system development, become more important. When considering safety and reliability design, at least two data sheet are necessary; Failure Modes and Effects Analyses (FMEA) and Risk Assessment (RA). These two data are practically made separately. However, it includes the concerns that a risk by failures during long-term use may not be noticed. To overcome this insufficiency, a support tool for integrating reliability evaluation and risk assessment data simultaneously is expected to be revealed. The authors have then developed a web-based design review system for reliability and safety system design. The system include various profitable functions; making FMEA and RA sheet, retrieving past data sheet for engineering change management and new product development and web-based discussion to increase the efficiency of discussion. The system is applied to one practical development works in order to demonstrate its effectiveness that is to be made clear by interviewing user's qualitative comment.

In Korea, more than half of work-related fatalities have occurred on construction sites. To reduce such occupational accidents, safety inspection by government agencies is essential in construction sites that present a high risk of serious accidents. To address this issue, this study developed risk prediction models of serious accidents in construction sites using five machine learning methods: support vector machine, random forest, XGBoost, LightGBM, and AutoML. To this end, 15 proactive information (e.g., number of stories and period of construction) that are usually available prior to construction were considered and two over-sampling techniques (SMOTE and ADASYN) were used to address the problem of class-imbalanced data. The results showed that all machine learning methods achieved 0.876~0.941 in the F1-score with the adoption of over-sampling techniques. LightGBM with ADASYN yielded the best prediction performance in both the F1-score (0.941) and the area under the ROC curve (0.941). The prediction models revealed four major features: number of stories, period of construction, excavation depth, and height. The prediction models developed in this study can be useful both for government agencies in prioritizing construction sites for safety inspection and for construction companies in establishing pre-construction preventive measures.

Global climate change is becoming one of the greatest challenges facing humanity. This article proposes a psychological perspective of climate change adaptation. Climate change-related severe adverse weather events may trigger mental health problems, including increased post-traumatic stress disorder (PTSD), depression, anxiety, violence, and even suicide. Forced migration could be considered a coping method for dealing with weather events, but it may also pose a psychological threat. People respond to severe weather events in different ways based on their individual characteristics. Psychological risks from adverse weather events are mediated and moderated by these factors, which are influenced by personal cognition, affect, and motivation. Examinations from a psychological perspective, which have been neglected in the science of climate change thus far, may provide keys to successful adaptation and the prevention of serious psychological problems resulting from the experience of severe weather events. A new prevention strategy has been suggested for coping with climate threats through encouraging attitude change, establishing proactive support systems for vulnerable groups, establishing a PTSD network, and implementing a stress inoculation program.

This paper rejuvenates the existing discussion on the importance of cluster approach to industry development strategies. Current evidences suggest that the shape of economic policy and practice is changing significantly around the world. Governments continually search for new tools and policy formulas to improve economic performance and create economic prosperity for all citizens. In this context a more proactive and strategic role for government in support of the cluster-based economic development model has emerged. This paper uses Singapore's petrochemical industry as an example to study the cluster approach to industry development. In doing so, there is much optimism to the importance of state and its institutions to play a significant role on industry development. Nevertheless, the study also raises doubts on whether the cluster-based strategy is due to the concept itself or due to other important factors.

Personalized reminder systems have to identify the user's current needs dynamically and proactively based on the user's current context. However, need identification methodologies and their feasible architectures for personalized reminder systems have so far been rare. Hence, this paper aims to propose a proactive need identification mechanism by applying agent and semantic web technologies and RFID-based context subsystem for a personalized reminder system, which is one of the supporting systems for a robust ubiquitous service support environment. We have created a prototype system, RFID-based NAMA (Need Aware Multi-Agent), to demonstrate the feasibility of the methodology and of the mobile settings framework that we propose in this paper. NAMA considers the context, user profile with preferences, and information about currently available services, to discover the user's current needs and then link the user to a set of services, which are implemented as web services.

This research was conducted in order to find out the effects of boys' self-control, their parents' behaviors and marital conflict on boys' aggression. Subtypes of aggression in the present research consist of dimensions of the functions and forms (proactive-overt, proactive-relational, reactive-overt, reactive-relational). The participants of this study were 237 boys in the fifth and sixth grades in elementary schools located in Seoul and Gyeonggi province. The questionnaires were derived and modified from Lee Hong (2009) for boys' aggression, from Ju So Young and Lee Yang Hee (2008) for boys' self-control, from Jun Joo Ram (2008) and Heo Seung Yeon (2009) for maternal behaviors and from Kang Na Jung (2008) for marital conflict. In order to grasp the general characteristics of the participants, frequency and descriptive statistics were used. Also, Pearson's correlation was applied to the relationships amomg boys' self-control, marital behaviors and marital conflict on boys' aggression. Lastly, the variables that can predict boys' aggression were analyzed through multiple regression analysis by SPSS 19.0. The major results of this study were as follows. This research showed that this model fit well for boys. To summarize the important results, what is interesting in the present study is the effect of the mother's role in rearing their sons. It was found that mothers' criticism, negative behaviors, and excessive interference can cause boys' high level of aggressiveness. Also, having parents who fight frequently was strongly associated with boys' relational aggression. An interesting finding is that the mother's support influenced boys' reactive-overt aggression. Lastly, boys' self-control was highly associated with boys' proactive-relational aggression. This research may contribute to understanding boys' aggression' subtypes. To that end, the current results suggest that the dimensions of the functions and forms may be a useful tool in an effort to inform developmental theory and intervention. Also, this research may provide guidance for the resolution of problems caused by boys' aggression. Lastly, it was found that self- control training and parental education programs might prove beneficial for helping aggressive boys to overcome their aggressive impulses.

최근 들어 휴대형 무선 기기들의 보급이 확대되고 WiBro/WiMAX/HSDPA 등의 고속 무선 데이터 통신 시스템의 등장에 따라 무선 환경에서 인터넷을 효과적으로 사용할 수 있는 이동성 관리 프로토콜에 대한 관심이 증가하고 있다. MIPv6(mobile IPv6)는 IPv6 환경에서 이동성을 지원하기 위한 프로토콜로 제안되었고, 이동이 빈번한 셀룰라 환경에서 효율적인 이동성 지원을 위해서 MIPv6의 핸드오버 성능을 개선한 HMIPv6(hierarchical MIPv6)와 FMIPv6(fast handovers for MIPv6) 등의 새로운 프로토콜에 대한 연구가 활발히 이루어지고 있다. 본 논문에서는 HMIPv6의 계층구조를 이용한 효율적 이동성 관리의 장점과 FMIPv6의 선행적 (proactive) 핸드오버 지원에 의한 끊임없는 서비스 지원의 장점을 효과적으로 결합하여 이동이 빈번한 셀룰러 환경에 적합한 새로운 이동성 관리 프로토콜인 HIMIPv6(highly integrated MIPv6)를 제안한다. HIMIPv6는 선행적 이동성 관리를 하위 도메인내의 핸드오버뿐만 아니라 하위 도메인간의 핸드오버에도 적용함으로써 시스템 전체적인 이동성 관리성능을 개선하였다. NS-2 시뮬레이션에 의한 성능 분석은 HIMIPv6가 빈번한 핸드오버 환경에서도 MIPv6, FMIPv6, 그리고 HMIPv6보다 이동성 지원에 필요한 신호 부하를 작게 발생시키고 핸드오버 상황에서의 서비스 끊김 현상이나 패킷 손실률도 작음을 보여준다.
