In recently, a climatic change(such as subtropical climate and frequent unusual high temperature) and the open-trade policies of agricultural & livestock products are increasing the outbreak risk of highly pathogenic avian influenza(HPAI) and foot and mouth disease(FMD), and accordingly the socio-economic damage and impacts are also increasing due to the cases such as damage from the last 5 times of FMD outbreak(3,800 billion won), from 10 years public control cost of Pine Wilt Disease (PWD)(238.3 billion won), and from the increased invasive pests of exotic plant like isoptera. Therefore, the establishment of new operation strategy of IoT(Internet of Things) based satellite early warning system(SEWS) for plants and animals as a subsystem of national disaster response and management system is being required, where the forensic technology & measures should be applied as a government policy to estimate the post compensation and to carry out the legal responsibility.

This essay explores the ways in which the philosophical concept of "original form" is expressed in relevant laws and regulations, the legal character of respective regulations, the way in which each regulation is applied in practice for heritage management, and the factors required for this concept to serve as a legally binding fundamental principle. The current laws and regulations on heritage maintain a consistent requirement for preserving the original form of heritage, both for the general public and for heritage professionals. However, the principle of preserving original form is expressed as a declaration or imperative without substantive definitions. Consequently, heritage administrators simply follow administrative procedures for heritage conservation, management, and promotion while failing to specify the meaning of "original form." For the practical application of the principle of preserving original form to overall heritage conservation activities as an actual legal principle, further provisions should be added for the purpose of clarifying the principle, with consideration given to the observation of fundamental principles for legal provisions, such as the principles of clarity, equality, and proportion. The principle of preserving original form still functions as the most necessary principle for heritage conservation and therefore should be reestablished as a refined and rational regulatory system.

In FPD WET equipment, heaters are used a lot. There are many electric accidents caused by short circuit and overheating due to the use of heater, so it is necessary to have a safe electric system and interlock. Therefore, in this paper, we propose an electrical schematic and interlock for FPD WET equipment. In this paper, a hardware interlock such as a level sensor, an overheat protector, and an SSR heater sink is inserted, and the electric system is composed of ELB - MC - SSR - EOCR - heater. When the interlock occurs, the magnetic contactor (MC) is turned off and the power of the heater is cut off.EOCR, an electric overcurrent protection device, has an interlock to shut down the MC when there is an abnormality in the heater while checking the overcurrent, undercurrent and disconnection. These circuit configurations and interlocks are likely to be useful not only for WET equipment but also for any equipment in which the heater is placed.

Recently, the US commanded a wargame simulation system of a combined ROK-US exercise with single federation. However, after the OPCON transfer, many limitations to the single federation have been cited such as security policies and information protection. We suggest a hierarchical federation as a way to overcome these problems. Regarding HLA rules, the participants use the same FOM and RTI in single federation. There are limitations to implement CI in applying heterogeneous FOMs and RTIs in current single federation. Therefore, we propose implementing CI with heterogeneous FOMs and RTIs in a hierarchical federation. This system overcomes the weaknesses of the system structure, which is a disadvantage of the single federation. In the federation test, we can apply heterogeneous FOMs and RTIs and achieve similar performance to the current combined exercise simulation. In conclusion, ROK should lead the simulation system of combined exercises using the CI after the OPCON transfer.

This paper is to suggest policy issues to be done in the future health policy for the elderly, analyzing contents of results suggested in academic papers published in Journal of the Korean Gerontological Society. Number of Papers published in the Journal is 61, occupying most of papers related with chronic disease, medical expenditures and health delivery system except dental and psychiatric health. Method used to be analyzed is mostly random sampling among community inhabitants or hospital patients. Policy issues are as follows in case of being based in the above analysis results. Firstly, it is necessary that the development of health promotion specialized for the elderly be developed and activated. Secondly, it is necessary that the primary health care system specialized for the elderly be constructed. Thirdly, it is necessary that the subacute care system specialized for the elderly be constructed after acute care services. Finally, it is necessary that the health care system specialized for the elderly in need of long-term care be constructed also.

This paper is to critically review the economic reasoning of non-sustainability of welfare state due to its intrinsic incentive problems and to see how the nordic welfare state responds to them. The welfare state as a political design of state to pursue equality has social insurance as its main economic function. It survives market failure of private insurance to contribute to human capital investment and industrial restructuring. The universal tax-financed welfare state, however, has the problem of tragedy of commons such as reduced work incentive and work ethics. But, the existing nordic welfare state overcomes it through employment-focused policy arrangements, maintenance of work ethics and benefits moral, incentive mechanism of wage-compression, public educational investment and its complementation with social security. The Nordic model shows that problems of incentive and moral are not about those of theory and reasoning, but about their reality which policies and institutions could respond to.

This study proposed a research model based on self-determination theory and unified theory of acceptance and use of technology to explain the factors influencing intention to use sharing economy services. A total of 392 responses were collected, and structural equation analysis was performed with AMOS 22.0. The results are summarized as follows. First, self-technological aptness and trust had a positive effect on intention to use sharing economy services. Second, access bigger market and environmental friendliness had a positive effect on intention to use sharing economy services. Third, intention to use sharing economy services had a positive effect on actual usage of sharing economy services. Finally, benefits was found to strengthen the relationship between intention to use sharing economy services and actual usage of sharing economy services. The findings of this study would provide a theoretical framework for sharing economy services and important information for understanding individuals using the sharing economy services.

The decrease in the school-age population caused the closure of private universities, but the guidelines at closed private universities are ambiguous, causing confusion. Therefore, this study intends to suggest a plan to utilize the closed school university. The government aims to increase the possibility of selling closed schools by preventing alley slums through the recovery of alley commercial districts and local communities. The data were collected through a Google survey from September 30 to October 8, 2021 and an on-site interview conducted on October 2, 2021. A total of 84 nearby citizens of the closed school university were surveyed, and on-site interviews were conducted with a total of five people. The collected data suggested the direction of utilization plan for closed school building. This study will present a model for the use of closed school property in the future and contribute to the establishment of urban regeneration policies.

In modern warfare, the importance of electronic warfare, which carries out a mission that using radio wave to find out enemy information or to protect ally information, has increased. Radar jamming technique is one of the most representative techniques of EA(Electronic Attack), it disturbs and deceives enemy radar system in order to secure ally location information. Velocity deception jamming technique, which is one of the radar jamming techniques, generally operate against pulse-doppler radar which use doppler effect in order to track target's velocity and location. Velocity Deception Jamming Technique can be implemented using DRFM(Digital Radio Frequency Memory) that performs Frequency Modulation. In this paper, I describe implementation method of VGPO/VGPI(Velocity Gate Pull-Off/Pull-In) velocity deception jamming technique using phase-sampled DRFM, and verify the operation of VGPO/VGPI velocity deception jamming technique with board test under signal injection condition.

Objectives : Modified Bo-Yang-Hwan-O-Tang (mBHT) is a polyherbal medicine of twelve herbs traditionally used in the treatment of cerebral and cardiac stroke and vascular dementia. The purpose of this study was to evaluate the neuroprotective effect, pyramidal neuronal cell, inflammation and apoptosis of mBHT against global ischemia in rats. Methods : Global ischemia was produced by two-vessel occlusion(2-VO) in SD male rats. mBHT at dose of 500 mg/kg was orally administrated for 2 weeks or 6 weeks after global ischemia. The histopathological changes of ischemic brain were observed by staining of hematoxylin and eosin (H&E) and Nissl and immunohistochemisty with anti-GFAP (glial fibrillary acidic protein) antibody as a astrocyte marker. The expression of inducible nitric oxide synthase (iNOS) and apoptotic proteins such as Bax, Bcl-2 and caspase-3 was determined by western blot. Results : mBHT treatment significantly inhibited the pyramidal neuronal loss in CA1 of hippocampus of global ischemic rats by 2-VO. mBHT also suppressed the activation of astrocytes in the CA1 at 6 weeks after ischemia. In addition, mBHT significantly increased the expression of anti-apoptotic protein, Bcl-2 on iscemic brain, and significantly attenuated the expression of apoptotic proteins, Bax and caspase-3. Conclusions : These results indicate that mBHT inhibits neuronal cell damage induced in global ischemia by 2-VO, suggesting that mBHT may be a potential candidate for the treatment of vascular dementia.
