This paper analyzes a social insurance system that integrates unemployment insurance with a pension program, allowing workers to borrow against their future wage income to finance consumption during an unemployment episode and thus improving their search incentives while reducing risks. This paper identifies the conditions under which the integration improves welfare and the factors which determine the optimal degree of integration. A fully integrated system is one in which no reliance is placed at all on a separate tax-funded unemployment insurance program. We show that when the duration of unemployment is very short compared to the period of employment or retirement, the optimal system involves an exclusive reliance on pension-funded self-insurance. This system imposes a negligible risk burden for workers while avoiding attenuating search incentives. We also argue that a joint integration of several social insurance programs with a pension program through an individual account is desirable unless the risks are perfectly correlated to each other.

Background: Apart from reducing occupational exposure to cytotoxic hazards, the PhaSeal(R) closed-system transfer device (CSTD) can extend the beyond-use dates (BUDs) of unfinished vials of antineoplastic drugs for up to 168 hours (seven days). In this study, the total material cost incurred by its use in a Malaysian government-funded hospital was calculated. Methods: A list of vial stability following initial needle punctures of 29 commonly-used antineoplastic drugs was compiled. The amount of the materials used, including drugs, infusion bottles, the PhaSeal(R) CSTD and other consumables, was recorded on a daily basis for three months in 2015. The total cost was calculated based on the actual acquisition costs, and was compared with that of a hypothetical scenario, whereby conventional syringe-needle sets were used for the same amounts of preparations. Results: The use of the PhaSeal(R) CSTD incurred a cost of MYR 383,634.52 (USD 92,072.28) in three months, representing an average of MYR 170.5 (USD 40.92) per preparation or an estimated annual cost of MYR 1,534,538.08 (USD 368,289.14). Compared with conventional syringe-needle approach, it is estimated to lead to an additional spending of MYR 148,627.68 (USD 35,670.64) yearly. Conclusion: Although there was a reduction of drug wastage achieved by extending BUDs of unfinished vials using the PhaSeal(R) CSTD, cost saving was not observed, likely attributable to the wide use of lower-priced generic drugs in Malaysia. Future studies should further evaluate the possibility of cost saving, especially in health settings where branded and high-cost antineoplastic drugs are more commonly used.

Nowadays, the demand of civil application of an UAV has been being increased all over the world. And many projects are going on to develop a new regulatory system for an UAV to access a national airspace. Especially, to fly UAV over the non-restricted airspace as a standard airworthiness standard, many authority funded research institutes and associations are studying regulatory environment. For the UAV to access civil airspace, the certification system of the aviation regulation have to allow this. FAA of US, CASA of Australia and European authorities are now issuing an experimental airworthiness certificate to a civil UAV. This is the first step of issuing a standard airworthiness certificate. And many people believe that civil UAV can fly over a NAS if some technical issues are resolved. In this study, I would like to present an international trends of a civil UAV regulation system, reliability trend of unmanned aerial system and would like to bring up a our regulatory environment and suggest an UAV regulatory policy.

In this paper, we propose a vision based passenger monitoring system for passenger's safety in railway station. Since 2005, Korea Railroad Research Institute (KRRI) has developed a vision based monitoring system, funded by Korean government, for passenger's safety in railway station. The proposed system uses various types of sensors, such as, stereo camera, thermal-camera and infrared sensor, in order to detects danger situations in platform area. Especially, detection process of the system exploits the stereo vision algorithm to improve detection accuracy. The paper describes the overall system configuration and proposed detection algorithm, and then verifies the system performance with extensive experimental results in a real station environment.

This paper presents the development and testing of a power conditioning system(PCS) for application to a 100kW Molten Carbonate Fuel Cell(MCFC) generation system. The MCFC generation system is a part of a four year government funded research project that began in 2001. This paper presents the results of various tests and performance verification of the 100kW PCS using a DC power system that simulates the DC output of the MCFC fuel cell. Performance of the DC/DC, DC/AC converters were verified, and basic control functions such as grid connection, protection and characteristics of each components were tested. The tests were performed under light load and rated load conditions to verify the operation efficiency, power quality effects, and stability of the PCS.

Recently, the hybrid system combining fuel cell and gas turbine has drawn much attention owing to its high efficiency and ultra low emission. It is now on the verge of world wide development and various system configurations have been proposed. A national project funded by Korean government has also been initiated to develop a pressurized hybrid system. This work aims at presenting design performance analysis for various possible system configurations as an initial step for the system development. Study focuses are given to major design options including the power ratio between gas turbine and fuel cell, reforming method (internal or external), reforming heat source (reforming burner, cathode hot air, fuel cell heat release) and steam supply method for reformer (anode gas recirculation, external steam generator). A wide variation in performance among different configurations has been predicted.

The paper presents the results of a study on the desired observing system which setting the high-level objectives for an integrated, sustained, national coastal observing system. Knowledge of the coastal zone is demanded by many constituencies, including fishermen, fisheries managers and climatologist, harbor pilots, coastal zone managers, environmental protection professionals etc. Many of these needs are being partially met by coastal zone observing system elements, both satellite and in situ. Nevertheless, these have not enough developed in an integrated manner and have been funded and operated to meet their own purpose. Thus, this study presents the development and application method for a national coastal zone observing system, which is integration of disparate observational systems and data sets to maximize their utility for many users and purposes.

This paper presents the brief generation process of system requirements for Smart UAV from a development objective. The current Smat UAV requirements deal with the restricted life cycle from development to test and verification exclusive of full life cycle because of the new technology demonstration research program funded by governments. The Smart UAV system consists of flight vehicle, avionics, communication link, payload, ground control station and ground supporting system. In this paper, top-down flown requirements are introduced how to allocate to each sub-system.
