  • In recent years, a variety of ITS services are available such as driving information, road conditions, V2X messages as well as navigation and traffic jams notification. The development of ITS services is accelerating by V2X communication technologies for high-speed vehicles. In this paper, WAVE communication devices based on the IEEE802.11p standard is introduced as a solution of V2X communication technologies. The H/W and S/W structures of the WAVE communication device and the characteristics of RF/antenna are described. The performance is evaluated in the test road by measuring throughput, PER and latency. The implemented WAVE communication device has 6~7 Mbps throughput with 10% PER at 1km coverage. The packet latency is less than 3ms for the whole test road. It is shown that the implemented WAVE technology is satisfactory to provide ITS services and Internet video-streaming services.

  • As data usage grows in importance, ensuring individual control over personal information becomes critical. The emergence of the 'MyData' concept addresses this, particularly in financial services. Although the institutional and technological framework for financial MyData services is in place, there's a need to establish consumer understanding and perception of its usefulness and safety for successful activation. This study focuses on investigating the impact of trust on the intention to use the new mobile banking service, financial MyData. This study has three objectives. Firstly, to analyze whether trust in financial MyData services and trust in financial MyData service providers affect the intention to use financial MyData services. Secondly, to analyze the process of forming trust in financial MyData services based on the phenomenon of transferring trust in service providers to trust in services. Thirdly, to identify the process by which trust transfer occurs between service providers and financial MyData services. Ultimately, the goal of this study is to promote the intention to use financial MyData services based on the concept of trust and to activate these services. In summary, this study emphasizes the significance of trust in financial MyData services, exploring its impact on user intention and the transfer of trust from providers to services. By promoting consumer trust, the research aims to contribute to the activation of financial MyData services.

  • The objective of this study is to provide direction for agricultural extension services in an age of localization. Agricultural extension services has carried out most of its activities by central direction and control. The central planning and management resulted in disappointment, inflexibility, and lack of responsiveness of the central bureaucracy. Facing localization in recent years, the extension system has not been satisfactorily developed to meet local demands. Korea has to choose to decentralize its extension services. The decentralization of extension services involves the transfer of planning, decision making, and management from the central government to the local level.

  • The subject of this study is to review the practical approaches of Home Care Services. Included is a brief overview of its nature, providers of Home Care Services, recent history of Home Care Services, and the impact of the national movement toward cost containment in health care. The data used in this study are obtained from the Elderly Program of the Medical Services and other data on the Home Care Services in Japan. With the growing elderly population in Japan, it is to be expected that the medical care expenditure for this sector will continue to increase. With the aim of keeping expenditure for medical care within reasonable bounds, it is essential that this increasing expenditure on the elderly be used effectively. With the Health and Medical Services Law for the Aged was enforced, therefore, remuneration for medical treatment of the elderly and what is known as the staff placement standard at hospital for the elderly were rationalized. In addition to rationalization from the point of view of medical care supply, it is necessary to guarantee the appropriate treatment within the community and at home for those elderly who are bedridden but not in need of hospital care. For this it is required that Home Care Services, such as health services like visiting guidance by public health nurse in hospital of Health Center. So that the elderly can feel secure in receiving treatment within the community and at home, allowances for guidance on leaving hospital and for intermittent nursing and guidance thereafter are to be newly introduced. Home care Services in one aspect of comprehensive health care, it is comprised of health services provided to individuals and families in their homes. Its purposes include promoting, maintaining and restoring health, specifically maximazing independent functioning and minimizing the disabling effects of illness, including terminal illness. Services appropriate to the needs of clients and their families are planned, coordinated, and delivered by providers organized for the delivery of home health care through the use of contractual arrangement, employed staff, or a combination of the two.

  • ITS (Intelligent Transportation System) has been more popular but ITS project managements remain complex because of diverse stakeholders and multidisciplinary processes of ITS. The multidisciplinary process enforces specialized competencies on ITS project managers comparing to other system integration project managers. In this paper, we derived core competencies of ITS projects from previous researches, built the hierarchy of the competencies, and employed AHP (Analytic Hierarchy Process) surveying ITS project managers and auditors with the hierarchy. Finally, we analyzed the difference of evaluation model on ITS project manager between project managers and auditors using Mann-Whitney U test. Additionally we suggest a method of building MECE (Mutually Exclusive and Collectively Exhaustive) structure for AHP using the HoQ (House of Quality). We expect our model to give some inspirations for raising capable ITS project managers and selecting a proper project manager for an ITS project.

  • The walnut (Juglans regia L.), a member of the Juglandaceae, is native to the mountain ranges of central Asia. This species of walnut is valued commercially for its nuts and in some areas for its timber. The seeds of walnut are recalcitrant and it has strong integument dormancy and their germination is irregular, making its natural propagation difficult. Low percentage of seed germination and long propagation cycle are the main problems of propagation. This study was conducted medium composition on in vitro plantlet regeneration from axillary buds of walnut. It has proved to be the most generally applicable and reliable method of in vitro propagation. Micropropagation culture that axillary buds are excised aseptically enables faster multiplication of plants. The axillary buds of walnut new cultivar "Sinlyeong" were cultured on two basal media which contained the different plant growth regulators depending on the respective shooting and rooting stage. After 12 weeks, the shoot generation rate was 85.3%, the shoot number and its length were 1.9/explant and 2.7 cm in the most favorable medium composition. The percentage of rooting was 25.4%. From these results, it was found the optimum basal medium and plant growth regulator for in vitro plant regeneration from axillary buds of walnut new cultivar "Sinlyeong". However, we have continued to search the other medium additives to enhance the rate of walnut root.

  • Allium ochotense and Allium microdictyon are commonly known as 'Mountain garlic' and are popular, economically important species in many countries such as Korea, China, and Mongolia. Their leaves are used as culinary side dishes and in traditional medicines. In Korea, these two species are at risk of extinction due to damage to their natural habitat and thus, conservation and breeding programs are needed. However, their identification relies mostly on morphological data, which is limited and until recently, led to classifying these two species under A. victorialis. In the present study, a simple and reliable method of molecular identification was developed to distinguish A. ochotense from A. microdictyon that targets four barcoding regions: the internal transcribed spacer (ITS), the maturase K gene (matK), the chloroplast psbA-trnH intergenic region, and the ribulose-bisphosphate carboxylase large subunit gene (rbcL). Single nucleotide polymorphisms (SNPs) were found in ITS and matK regions, and species-specific primers were designed based solely on the SNP at position 680 of the ITS region that could differentiate A. ochotense from A. microdictyon. Using these primers in amplification refractory mutation system (ARMS)-PCR, A. ochotense, and A. microdictyon could be simultaneously and efficiently distinguished. This study is the first to report a simple, rapid, and efficient method for discriminating A. ochotense and A. microdictyon, indicating the utility of species-specific markers in the development of conservation and breeding programs.
