  • To better publish geographical information on the Web, it is important to capture how Web technologies are changing. For a recent decade, Semantic Web has been developed by incorporating ontologies into the current Web, with an aim to make computers understand rather than simply display. Ontology, an explicit specification of a conceptualization, and the Semantic Web grounded on the ontology, have the potential for effective sharing and appropriate retrieval of geographical information. This paper describes a Semantic Web Service over the mobile Web that can offer pertinent tourism information according to user contexts. To do this, a tourism ontology was formalized in the PARA(Place-Attraction-Resource-Activity) ontology model by organizing tourist places, tourist attractions, tourism resources, and activities. Locational relationships between tourist places were also included in the PARA ontology model to take into account the movements of tourists on a railway network. The XML(Extensible Markup Language) Web Service in the middle tier manages the client-side request for information retrieval and the corresponding server-side response from the data provider. The PARA ontology was integrated into the XML Web Service for the concept-based discovery of tourism information. The applicability of the proposed system was tested through a simulation experiment for Tokyo tourism.

  • This study aims to examine the patterns of middle-aged parents' intergenerational support exchange with their adult children and its effects on the happiness of the parents. The sample consisted of 765 middle-aged parents selected from the National Survey of Korean Families by the Ministry of Equality and Family in 2010. The results were as follows. First, intergenerational support exchange between parents and their adult children was categorized into four groups depending on the provider of support: parents who exchanged no support with their children, parents who only received support from their children, parents who only provided support to their children, and parents who exchanged support with their children. Second, parents who exchanged no support with their children were high in instrumental support and those who both provided and received support were high in emotional support. Third, consciousness of their children significantly affected the satisfaction level of their relationship with their children. The more the parents emphasize on the growth of their children, the more they were satisfied. Parents in the support exchange group were more satisfied when they received economic support from their children. With regard to instrumental and emotional support, parents were more satisfied when they provided support to or mutually exchanged support with their children. Forth, subjective health conditions, consciousness of their children, and household's income more significantly affected the happiness of middle-aged parents than the patterns of intergenerational support exchange. With regard to economic support, parents who only received support from their children were less happy than the other groups. With regard to instrumental support, parents who exchanged no support with their children were happier than the other groups. With regard to emotional support, parents who provided support to their children were happier than the other groups.

  • The P2P service is a technology that can share their information with each other who is able to be connected ith a relating program without passing by a server. Since all personal compiters that linked to the internet under the P2P service can opetate as server or a client, they can provide and share both their information and services through the direct connection. Currently, the P2P service is giving an equal privilege to all users for sharing their resources,.Under this situation, a lot of vulnerability against the various sttacks through the Unternet is possoble, more sophisticated security services are necessary. In this paper, We propose and access control schemae using SPKI(Simple Public Key Infrastructure). The scheme designates and access and acces control by providing the certificate to users who request a connection for resource sharing and limits the resource usage of information provider according to the access right that is given to their own rights.

  • Real-time traffic information disseminated through VMS is known to have effects not only on driver to plan a route choice, detour the congestion, and cope with incident, but also on VMS operator to manage the traffic volume indirectly. But, the dissemination of traffic information is operated in the side of provider, not of user. Importance-Performance analysis (IPA) offers a simple, useful method for simultaneously considering both the importance and performance dimensions when evaluating or improving strategy. This technique has been successfully used in a variety of settings to define priorities and guide resource optimization decisions. This study uses IPA to evaluate traffic information strategies through VMS to make resource improvement recommendations. It gained 760 samples by field surveys, which are conducted in Korean Thanksgiving Day, weekday and weekend at the service areas of expressways. The results indicate that the motivations in quadrant I (concentrate here) are dissemination of exactly information and quick transmission, while distance of VMS, most drivers are not satisfied with that is located in quadrant III (low priority).

  • The enforcement of the Nagoya Protocol, which regulates the acquisition and use of genetic sources, an essential material for biotechnology R&D, has imposed a burden for additional documentation works to researchers. In the past, countries regarded genetic resources as a common human heritage and thus allowed researchers to use them freely. However, they can no longer afford the luxury of such freedom now since many countries are introducing new laws and regulations on the acquisition and use of the resources as the Nagoya Protocol recognizes the exclusive ownership of genetic resources. Therefore, Korea, which is highly dependent on foreign genetic resources, needs a more systematic response. This paper aims to review the key contents of the Nagoya Protocol to raise awareness among domestic and foreign genetic resource users, including researchers of environment and ecology and present the overall structure, and flow of acquisition, access, and benefit sharing (ABS) for the use of foreign genetic resources to help them respond appropriately to the new landscape. The researchers' efforts and support at the national level are necessary at the same time to appropriately respond to the Nagoya Protocol. First, the researchers must understand the overall framework and the specific response in each stage under the Nagoya Protocol scheme. It is necessary to respond to the ABS procedure of the resource provider country from accessing genetic resources to sharing benefits resulting from it. In that regard, the Nagoya Protocol has imposed more restrictions on research activities and raised the burden outside of research. The current trend of recognizing the country's sovereign rights over genetic resources is likely to continue and widespread worldwide as resource-rich countries are expected to continue protecting their resources. Therefore, our study will help environmental ecology researchers understand ABS and conduct research under the Nagoya Protocol and legal obligations of resource provider countries step by step, from access to benefit sharing.

  • Cloud service users request dedicated virtual computing resource from the cloud service provider to process jobs in independent environment from other users. To optimize this process with automated method, in this paper we proposed a framework for workflow scheduling in the cloud environment, in which the core component is the middleware called broker mediating the interaction between users and cloud service providers. To process jobs in on-demand and virtualized resources from cloud service providers, many papers propose scheduling algorithms that allocate jobs to virtual machines which are dedicated to one machine one job. With this method, the isolation of being processed jobs is guaranteed, but we can't use each resource to its fullest computing capacity with high efficiency in resource utilization. This paper therefore proposed a cost-efficient job scheduling algorithm which maximizes the utilization of managed resources with increasing the degree of multiprogramming to reduce the number of needed virtual machines; consequently we can save the cost for processing requests. We also consider the performance degradation in proposed scheme with thrashing and context switching. By evaluating the experimental results, we have shown that the proposed scheme has better cost-performance feature compared to an existing scheme.

  • The main purpose of this research is to figure out systematically the total amount of social welfare resources in Korea. For the stated purpose, this research (1) defines the concept of social welfare resource, (2) develops basic framework for measuring total amount of resources, (3) estimates total amount of social welfare resources based on the year of 2004, and (4) presents some implications of findings. Social welfare resource is defined as any valuable things, material or immaterial, that one can put into instrumental use in order to meet social needs or to resolve problems in the interaction process between human and the environment. Institutional sectors of social welfare resource consist the following 5 major areas derived from resource providers: The government, enterprise, market, the third sector (religion & welfare institutions, fundraising agencies, and NPOs), and community (families, relatives, and neighborhoods). For the estimation of the total amount of social welfare resources, this research takes advantages of both the major methods of provider centered approach and the intermediary agent centered approach. Based on the compromised method estimation, the total amount of social welfare resources in Korea in the year of 2004 is 147 trillion won (approximately, 148 billion dollars and 19% of GDP). Among them, central and local governments provide 52 trillion won. The private sector expends a total of 109 trillion won, which contains 44 trillion from enterprise, 54.3 trillion from market, 3.0 trillion from the third sector, and 8.3 trillion from the community. The enterprise and market share of welfare resources exceeds 66% of the total expenditure, and the market is expected to increase gradually in the near future.

  • 수요 반응 프로그램은 크게 인센티브 기반 수요 반응 프로그램과 가격 기반 수요 반응 프로그램으로 나눌 수 있다. 인센티브 기반 수요 반응 프로그램은 용량 요금 형태의 보상금을 지급하고 전력 시스템의 안정적 운영을 위해 긴급 상황 시, 이벤트를 통해 호출 됨으로써 중요성이 더욱 부각되고 있다. 신뢰도 수요 반응 자원들은 운영주체와의 사전 계약 시, 자신의 월 또는 연간 사용 한도를 정하고 계약을 하게 된다. 이는 빈번한 수요 자원 호출로 인해 수요 자원 보유자가 효과적으로 반응하지 못하게 됨을 방지하기 위함이다. 본 논문에서는 이러한 수요자원의 최대 사용 횟수를 고려하여 신뢰도 수요 반응 프로그램의 스케줄링 방법을 제안하였다. 본 스케줄링 방법은 각 이벤트별 필요 수요 자원량과 각 수요 자원들의 비용을 고려하여 특정 기간동안의 계획을 수립하는 것으로써, 현재 널리 이용되는 단기 스케줄링과 비교하였을 때, 운영주체의 비용을 절감할 수 있게 된다.

  • The purpose of this study was to develop the generative fathering scale to measure fathers' active involvement of parenting. Subjects were 188 fathers of early childhood from Jeonju. To begin with, the concept of generative fathering was discussed in the theoretical review, and then the measurement was comprised of two dimensions(the parental involvement of fathers and paternal responsibility) The parental involvement of fathers : thirty of 37 items were selected through the item analysis, and that 30 items were analyzed by factor analysis. The result of factor analysis indicated that the parental involvement of fathers comprised of three factors(developmental support, caregiving and monitoring, shared activities). paternal responsibility : this was analyzed through the same process above, two factors(responsibility as a resource provider and responsibility as a child-rearing)were extracted by factor analysis. The construct validity was supported and the internal consistency of this two sub-scale appeared to be at an acceptable level, and were considered to be useful way to measure generative fathering.

  • Purpose: To reilluminate academic fundamentals and missions of child health nursing (CHN). Methods: Critical review of literature. Results & Conclusion: The academic fundamentals of CHN were analyzed for three different basis; philosophical, theoretical, and legal & ethical basis. The philosophical basis of CHN was summarized as six beliefs; A child is an important human resource and a valuable asset for future society; A child should be respected as a unique and dignified human being; A child has his/her own unique developmental needs; A child is a vulnerable client and should be advocated for; Atraumatic care should be provided to each child; Child health care should be family-centered. The essence of the theoretical basis were reilluminated into caring theory and client advocacy theory. The legal basis of CHN was stated as pertaining to the various child-related laws and international conventions, such as UN Convention on the Rights of the Child. The ethical basis were stated as 4 principles of biomedical ethics and The UNESCO Universal Declaration on Bioethics and Human Rights. The mission of the CHN was stated and the role of CHN was described as one who is a child rights advocator, professional caring service provider, policy maker, health educator, researcher.
