The purposes of this research were to investigate home care rehabilitation services in rural areas and to collect basic data about disabled persons necessary when for carrying out rehabilitation services. Respondents were selected from six of a total of eight townships (Myon) and one town (Eup) in the Wonju city area. Wonju is in Kangwon Province (Do). Of a total of 338 names provided by the Myon offices, 298 persons were located and included registered and non-registered persons. Conditions included stroke, spinal cord injury, and cerebral palsy in addition to disabilities classified as first, second or third degree, in the case of registered cases. Respondent demographic characteristics, medical characteristics, rehabilitation service needs, willingness to receive rehabilitation service and individual opinions regarding rehabilitation services were analysed by frequency and percentage. The results were as follows: 1) Rehabilitation services received by disabled persons living at home in the rural areas surrounding Wonju city were medical rehabilitation (41.7%), diagnosis (36.5%), rehabilitation assistive devices (7.6%), social assistance (7.1%), rehabilitation counseling (3.0%), vocational rehabilitation (1.8%), educational rehabilitation (1.6%) and housekeeping services (0.5%). The majority of rehabilitation services were medical rehabilitation provided at hospitals and oriental medicine hospitals. 2) Sixty point eight percent of respondents expressed their willingness to receive home care rehabilitation services. Needs expressed were highest for medical rehabilitation (27.0%), followed by social assistance (19.4%), medical examination (12.4%), physician-generated diagnosis in the home setting (11.6%), sociopsychological rehabilitation (9.3%), vocational rehabilitation (7.6%), rehabilitation engineering (6.0%), educational rehabilitation (3.3%), and housekeeping services (3.3%). 3) Rehabilitation service needs were analyzed by severity classification: 65.8% of first degree, 62.7% of second degree and 55.6% of third degree disability classification, and 62.7% of non-registered disabled individuals responded that rehabilitation service was necessary. 4) Rehabilitation service needs were also analyzed by diagnosis: 62.6% of stroke, 85.5% of amputation, 60.0% of spinal cord injury and 52.4% of traumatic brain injury respondents answered positively that they were willing to receive rehabilitation service if it were to be provided. Rehabilitation service utilization data of disabled individuals living at home in rural areas were investigated and their rehabilitation needs analyzed. This critical information can be used when community-based rehabilitation programs for disabled persons living at home are planned for provision out of a public health center or when community-based rehabilitation welfare policy is formulated.

Certificates of Origin(C/O) are necessary to gain benefits from preferential tariff treatment under the Free Trade Agreement(FTA). The C/O can be issued by issuing authorities or by exporters themselves. Recently, due to signed FTA such as Korean-EU FTA, issuance of self-declared C/O by exporters is increasing. In order to be qualified to issue self -declared C/O, exporters are required to acquire Approved Exporter status. An Approved Exporter is only required to present an invoice to substitute the certificate. The invoice contains an Approved Exporter number and a declaration that states the goods comply with the origin requirements. Either certification or notarization is not necessary. In result, the exporters are responsible for application of a preferential tariff under the self-declared C/O which issued incorrectly, even if it is not intentional. Therefore, in this paper, we studied authorization for Approved Exporter status and the practical use of its status. If companies obtain more Approved Exporter status, the effects of FTA would be maximized due to application of a preferential tariff under the C/O.

This study deals with the policy proposals focusing on the addiction for the rapidly growing social media service (SNS) and its diagnosis. Researcher intends to define the SNS addiction and develops a diagnostic measure, which is a valuable subject. The reason is why the SNS becomes more convenient with prevalence of smart phones and the SNS addiction becomes enough severe to suggest internet addiction policy. Researcher presents the subjects into three parts. Firstly, the SNS addiction variables are derived and validated. Secondly, the path model between the SNS addiction variables is verified and discussed. Thirdly, researcher proposes the diagnostic results and the group comparison. Therefore, the result of this study is that the SNS addiction can be measured by the four elements, which are the failure in stopping the use of the SNS, time tolerance, living disability, withdrawal and anxiety. Researcher verifies the sequential impact of each variable and figures out the SNS addict through the presentation of a realistic measurement for the addiction index and the determination of the level of the addiction. By the above result, the researcher proposes the public relations of the government policy for the sound usage of the SNS and the self management of user. Finally, various proposed in this study will help to prevent juvenile crime, social problems in the future.

This study is designed to support the development and the teaching of revised curriculum of 2007 "Technology & Home Economics" by investigating the actual condition and the necessity of education for elderly housing education. Questionnaire survey was conducted with 488 high school students in Gyeongnam in 2008. The data analyzed by descriptive statistics, t-test, One-way ANOVA, Duncan's multiple range test by using SPSS 14 program. The results showed that most of the students were dissatisfied with their middle school education of elderly housing due to the lack of interesting and practical contents. Thus, various teaching-learning methods where student can experience and experiment is needed. Also, the students demanded more of factors of elderly housing, spacing plan, elderly welfare service and less of three-generation housing and senior housing in their elderly housing education. The needs of education contents differed among students depending on variables such as sex, graduated middle school, household income, dwelling space and length of residential years. Therefore, revised 2007 curriculum of "Technology & Home Economics" should include required contents in related chapters. Because there are significant differences among textbooks about elderly housing, further attention needs to be paid to the new textbooks in order to include education contents evenly. At the same time, teachers should organize their teaching contents considering the divergence of variables. The effect of elderly housing education will be maximized if the revised curriculum consists of more experimental activities such as elderly simulation in the local community.

The Internet of Things is a huge group of devices communicating each other and the interconnection of objects in the network is a basic requirement. Choosing a reliable device is critical because malicious devices can compromise networks and services. However, it is difficult to create a trust management model due to the mobility and resource constraints of IoT devices. For the centralized approach, there are issues of single point of failure and resource expansion and for the distributed approach, it allows to expand network without additional equipment by interconnecting each other, but it has limitations in data exchange and storage with limited resources and is difficult to ensure consistency. Recently, trust management models using fog nodes and blockchain have been proposed. However, blockchain has problems of low throughput and delay. Therefore, in this paper, a trust management model for selecting reliable devices in a fog-based IoT environment is proposed by applying IOTA, a blockchain technology for the Internet of Things. In this model, Directed Acyclic Graph-based ledger structure manages trust data without falsification and improves the low throughput and scalability problems of blockchain.

Urban green spaces, as a means to mitigate social problems and environmental risks, are getting more attention in evaluating urban environment. The inequity of green space distribution is becoming a major issue in urban planning and management. This study investigated the characteristics of green space in 3 districts (Jung-gu, Dongdaemun-gu, Seongdong-gu), that are composed of 46 administrative divisions in central Seoul, to analyze the environmental equity of urban green spaces. The correlations between the amount of green space, including the coverage of street trees, and the socioeconomic status of each administrative division were analyzed. To deduce the effects of plant coverage on the urban temperature regime, the relationship between the normalized difference of vegetation index (NDVI) and land surface temperature (LST) was analyzed. The research revealed that the mean NDVI of an administrative division was negatively correlated with the percentage of basic living recipients and disabled people. The LST of a division with low NDVI was higher due to the lack of green coverage. Such environmental inequities were closely related to residential building type, which was strongly affected by the economic status of residents. The LST of an apartment area was $2.0^{\circ}C$ lower than that of single-family houses and multi-housing areas. This is expected as the average NDVI of the apartment area was more than twice as high as the other environments considered in this study. The inequity can be exacerbated without urban planning which is deliberately designed to reduce it.

An electric vehicle is emerging as an alternative to the response of global climate change and sustainability. However, an Electric vehicle has not been popular due to the constraints such as its price or technical limitations. In order to analyze the effect of purchasing electric vehicles, this study conducted a binary logistic regression model that demonstrates the relation between purchasing and influencing variables. Variables which have high correlation were excluded from the model through the correlation analysis to prevent multicollinearity. Socio-economic variables such as the number of owned vehicles, sex, ages are not significant. On the other hand, Variables related to prices, charging and policy are found to have a significant to effect on the purchase of electric vehicles. In accordance with the model estimated result, it seems to be necessary to improve the charging incentives, or to provide electric car information and to expand opportunities for experience electric vehicles. The result is also expected to be helpful for spreading electric vehicles and formulating policies.

In order to provide the Mobile Stations operating in IEEE 802.11 Wireless LAN network with seamless handover, a comprehensive study on the functions of handover considering various networking environments and characteristics of Mobile Stations is required. Note that the channel scan process finding a new AP takes the major portion of handover time, and this is the most significant issue with seamless handover for real-time multimedia service in WLAN environment. In this paper the functions required to provide seamless handover in IEEE 802.11 WLAN network are identified, and a new scanning technique is proposed with which the Mobile Stations can selectively scan the channels to reduce the channel scan time in various network environments. Here each Mobile Station awares of the channels the neighbor APs are using by scanning them in advance according to the proposed technique. Afterwards, when handover is actually required, the optimal AP is decided quickly by scanning only the predetemined group of channels and order of scan without unnecessary scan of all the channels. In addition, proposes to enter the Scan Trigger Value and Handover Threshold Value in mobile phones in order to prevent the phenomenon can not handover.
