Objectives: This study described the features of home-bound industrial accident victims and their needs for rehabilitation services. This study was also aimed to find a future direction of development of community rehabilitation programs that are suitable for their needs demands. Methods: This study is a descriptive study, were collected through two phases using structured questionnaire. In the first stage, su were performed via telephone interviews. In the se stage, surveys were performed via home visit Subjects in the first stage included 2203 indu injured victims staying at home, of whom. individuals complaining of post-traumatic complic became the subjects of the second stage. Results: This study showed that the home-bound industrial accident patients were complaining of complications from the injury even after receiving treatment by IACI. However, they were neglecting their health problems without any intervention. Even if they use health care services. the treatment is mainly focused on acute medical care, which may not effective for them. Furthermore, they had unstable employment status and suffered from financial burden for health care costs. The Labor Welfare Organization has established a plan to remove barriers of industrial accident victims in reinstatement, and has been preparing various programs in order to establish an all-embracing service system for industrial accident victims from accident occurrence to reinstatement. However, these rehabilitation services can be truly helpful only when the injured are able to obtain enough information about them. The current restrictive system is also not appropriate for solving health problems of the industrial accident victims. Therefore, it is necessary to develop a plan that can provide industrial accident victims high-quality rehabilitation services so that they can use those services in the community without being dependent on hospitals. This study proposes visit nursing services as a way to provide various health services within community for the industrial accident victims.

The purpose of this study is to provide appropriate methodology to ensure the safety and integrity of the production riser in offshore structure. In order to select integrity estimation methodology for production riser, level I and II Non-destructive Damage Evaluation (NDE) methods that were applied to existing structures are classified and reviewed. Numerical analysis is performed to verify the applicability and capability on damage detection of reviewed methods. As a result, the damage detection methodology using modal strain energy is more sensitive in detection of the damage than other methods. In practice, the number of sensors is limited due to the environmental and financial conditions. The impact on damage detection performance by reducing the number of sensors is systematically investigated through a series of numerical analyses and the results are discussed. The optimal number of sensor for the integrity estimation of production riser is recommended.

The restructuring of Korean railway industry, separation of between train operators and an infrastructure manager, had been conducted in 2004 to increase the productivities of railway operations. However, the maintenance-staffs are still employed by Korail (train operator), not by the infrastructure manager, which led the maintenance of railway infrastructure to be conducted by the train operator. The infrastructure manager is now only taking care of financial transferring issues once the train operator requests expenses spent for facility maintenance. Such incomplete restructure may result in a lack of safety performance on railway operations as the roles and responsibilities are less likely to be assigned under the multiple train operators. Thus, this study proposes the way of structuring maintenance divisions and their roles and responsibilities to assure the safe work execution under the circumstance of multiple train operators on the same rail network.

The Korean government has actively accepted private investments in building expressways to improve its financial status. As of 2012, 422km of 9 private expressways are under operation, and until 2016 additional 15 are planned to be built with private investments. However, on average, each private expressway is at most 37km long, which works against economies of scale in maintenance and thus leads to inefficiencies such as traffic jams, driver inconveniences, and the increase in operating costs. To resolve these problems, the present study suggested that the maintenance and tolling system should be unified across each private operator. Unifying the operation of private expressways was expected to reduce user travel times and tolls, and save operator maintenance costs. These economic effects were expected to be tantamount to hundreds of billions of dollars. The shared toll collecting system will also reduce user's delays by removing main line tollgates. This can save another hundreds of billions of dollars by ensuring driver's convenience and safety.

Background : Because hospitals had to faced with financial hardship, we have to have more effective hospital management. In this study, we tried to improve job performance and to reduce cost maintaining safety in fields of patients care. Methods : Central Supply Room(CSR) staffs taught strategy of material cost reduction to middle level managers and staffs 14 times. All staffs and voluntary service workers, working in 33 nursing units, participated in this activity. We developed questionnaire to check the degree of participate in cost reduction activity and job performance in CSR, and quality improvement in the wards. Two hundred questionnaires were distributed and 197 returned. Results : Because CSR staffs developed new items and every item was managed at each department, stocks of each department were reduced. Overall, by comparing before and after cost reduction activity, almost 1.2 billion won reduced for one year. Staffs' loyalty and spirits of cost reduction were improved by changing clothes and duty environment. Furthermore, these activity improved patients' satisfaction. Conclusion : We suggest that CSR activity in a university hospital contributes to improve job performance and to reduce cost without any problem in patient care.

Regarding the official authentication method which is a strong encrypt method for financial transactions, there has recently been a concern for the problem of storage. As a solution for such problems, this study provides the anonymous authentication method based on the smart card used for such a purpose by utilizing the pseudo ID replacing the user's personal data. Such an anonymous authentication method makes it possible to prevent any inside leakage, intermediary attack, limited re-transmission attack, service-denying attack, directional safety attack and secret inspector attack in regard to the user's personal data. As a result, there would be no concern for the leakage of any personal data. In comparative analysis, after executing the comparison and analysis process through the experiment for the authentication process by using the previously-used smart card, the new one has shown about 10% a high level of efficiency for the encrypt and decrypt process together with excellent features in terms of flexibility in regard to the user's anonymity and tracking ability.

Ubiquitous computing is a study area explained in a myriad of contexts and technological terms. Payment, however, refers in nature to an act of money transfer from one entity to another, and it is obvious that a payment method will be valued as long as the transaction can be completed with safety no matter what technology was used. The key to U-payment is convenience and security in the transfer of financial information. The purpose of this paper is to find a desirable U-payment scheme by looking at the characteristics of seamlessness under the ubiquitous environments, strong personal device, and peer-based information transactions. We also propose U-SDT Protocol integrating technologies such as Radio Frequency Identification (RFID), Bluetooth, Personal Payment Device, Account Managing Application and Transaction ID as a way to make transactions between users seamless and secure better privacy protection.
