Purpose - With rapid population aging in Korea, changes in the population structure will result in a rise in the fiscal burden. This paper investigates the effects of population aging on fiscal spending based on Korea's province data and country panel data from the OECD. Research design, data, and methodology - We use province-level fiscal data from Local Finance Integrated Open System and the Korean Statistical Information Service and also collect country panel data from the OECD. To investigate the relationship between population aging and fiscal expenditures, our analysis uses the fixed effects model. Results - The empirical analysis based on Korean local finance and country panel data show that population aging has a positive impact on social welfare expenditures and it also has a positive impact on spending related to children and the elderly, implying that population aging may lead to an increase in fiscal spending via an increase in social welfare expenditures and spending related to children and the elderly. Conclusion - These empirical results suggest that countries like Korea that expect to experience rapid population aging need to pay more attention to prepare for the expected increase in age-related spending in the near future.

Hotel companies have to offer well furnished of a lodging and a meal and must keep the best customer supporting service. Because, customers have very strict standards and require fancy service to hotel that they pay. The Customers have different criteria to select hotel according to their purpose such as accommodation, banquet or convention. Hotel recognitions are also different along the purposes. I analyzed effects of hotel choice by intention to use hotel of customers in this research. To verify the effects, I used a structured model by AMOS 4.0 This study results show that the customers chose hotel in accordance with their intention of stay ; accommodation, banquet or convention etc. However, it is not significant hypothesis, that the guests select hotel along the brand recognition or the service perception.

Intra-industry trade (IIT) has played an important role in international trade of Vietnam as a result of rapid growth of the country. This article investigates the level of IIT between Vietnam and 11 trading partners in Trans-Pacific Partnership (TPP) over the period 2000-2014. Although there have been a large number of empirical researches contributed to the determinants of IIT, most of them only pay attention on developed countries where the trade flows are similar due to similar demand structure and production technology. Until now, there is no study on intra-industry trade between Vietnam and countries in TPP that Vietnam recently signed a trade agreement in early 2016. IIT is measured by the Grubel-Lloyd index. The index shows that the extent of intra-industry trade between Vietnam and the trading countries is not high due to the level of economic development and the market size. The determinants of IIT are examined using a panel regression model. In the empirical analysis, the results indicate that Vietnam's intra-industry trade is positively correlated with country size, while it is negatively correlated with income dissimilarity, the trade openness, and geographical distance. This study contributes to the new theoretical trade theory on the evidence of developing country's IIT.

There werer many researches on the switch system for high speed netowrk such as B-ISDN and the server system for the multimedia services respectively. But, in case of simple connection of these two systems, we have to suffer the bottlenck problem of data transmission, and pay the wasteful expenditure because of duplicated architecture of both systems such as interconnecting network at the switch and the server. Therefore, we propse the unified architecture of switehces and servers, which can be used as switches and servers simultaneously. This is based on the hybercube structure. The links are used iterconnection network of switch system, and each node has the subscriber subsystem and the server subsystem. The proposed architecure has the benifits as follows; the easy espansion of capacity due to the scalability,the simple system development and maintenance because of the equivalance of each nodes, the high reliability against the fault of nodes and links due to the existence of the many alternative links between nodes, the easy flow and QoS managment due to the non-blocking data transmission between any two nodes, the flexible adaptation for additional new services owing to simple insertion server board to node. In this paper, we present overal configuration and node component of proposed architecture, and the procesing flow for the various services.

This study examines whether Korean rating agencies such as Korea Investors Service (KIS), National Information & Credit Evaluation (NICE), and Korea Ratings Corporation (KR), incorporate corporate governance into their corporate bond ratings in Korea. We find that the Korean rating agencies assign higher ratings to the bonds issued by Chaebol (Korean business group) affiliated firms. Our results also indicate that those rating agencies give higher ratings to the bonds with greater foreign investor share ownership. Moreover, if the rating agencies value corporate governance, higher rated firms should issue bonds at lower yield to maturity. We discover that Chaebol affiliation is counted favorably by the rating agencies. We find that investors are willing to pay lower risk premium for bonds with higher institutional ownership, but higher risk premium to bonds with greater equity ownership in the form of depository receipts. Therefore, even if the rating agencies and investors in Korea consider corporate governance (Chaebol affiliation and ownership structure) an important determinant in bond ratings and the yields to maturity, they have opposite views on institutional ownership and share ownership in the form of depository receipts.

This study investigates the different pattern of trade negotiation between Korea and Japan. For the Korea, it is inevitable to enhance nation's competitiveness position amid the rapidly changed international environment. Especially, Korea's recent experience of IMF credit under economic crisis during 1997-1999 tells us the importance of international trade and trade negotiation. Our main interest is focused on the comparative pattern of both countries with the recognition that the role of the negotiation can not be overemphasized for the Korea. This is because Korea has continuously recorded the huge trade deficits with Japan for the long time. Although we consider the different degrees of products quality, industrial structure, productivity, and national competitiveness of both countries, it is necessarily required to pay special attention on different pattern of negotiation skills and tactics between two countries. In the paper, we suggest some important guidelines for Korea to improve its negotiation technique with Japan. First, valuing human relation between negotiators, rather than negotiating process. Second, preparing for negotiations: the negotiators should try to carve out enough time to prepare for the bargaining. Third, appreciating the power of patience: very essential to effective outputs. Fourth, being a specialist on both countries' culture and avoiding lawyers' intervention for conflict resolution.

An investigation was conducted to get the basic data for establishing maintenance strategy of pipe framed greenhouses. The contents of the investigation consisted of actual state of structures, maintenance status, meteorological disaster, and corrosion characteristics of pipe framework in greenhouses. the number of greenhouses investigated was 108 in total. Most multi-span greenhouses had narrower width and lower height than the standared 1-2W greenhouse, and most of single-span greenhouses were tunnel type. In multi-span greenhouses, the size and interval of frameworks such as rafter, purline, column , and cross beam were mostly suitable, but frameworks of single-span greenhouses were mostly insufficient. After about 7 years in grounds, 8 years in joints, 10 years in bending parts. and 13 years in columns. pipe surface was mostly rusted. Most weak parts in corrosion were pipes in contact with the ground, joints, roll-up shaft pipes, and pipes close to the gutter. Almost all of the greenhouse farmers didn't pay any attention to maintenance affair in a regular interval for pipe framed grenhouses. Many greenhouses have experienced the meteorologicla diaster such as uplift of foundation, partial or complete failure by the hyphoon and/or high winds.

We investigate the morphology of Active Galactic Nuclei(AGN) jets. AGN jets propagate over kpc $\~$ Mpc and their beam velocities are close to the speed of light. The reason why many jets propagate over so long a distance and sustain a very collimated structure is not well understood. It is argued that some dimensionless parameters, the density and the pressure ratio of the jet beam and the ambient gas, the Mach number of the beam, and relative speed of the beam compared to the speed of light, are very useful to understand the morphology of jets namely, bow shocks, cocoons, nodes etc. The role of each parameters has been studied by numerical simulations. But more research is necessary to understand it systematically. We have developed 2D relativistic hydrodynamic code to analyze relativistic jets. We pay attention to the propagation velocity which is derived from 1D momentum balance in the frame of the working surface. We show some of our models and discuss the dependence of the morphology of jets on the parameter.

The purpose of this study is to secure reasonable transportation infrastructure stock for enhancing national competitiveness in Korea. National competitiveness may be defined as a country's overall capacity to create the most effective social structure, institutions and policies that allow her company within the national boundary to be more competitive in the world market. If Korea's transportation infrastructure stock is not sufficient and a connection among transportation facilities is not efficient, we should pay the social and economic cost. As a result, we worry that national competitiveness may drop. Some methods to maintain or to increase the national investment for transportation infrastructure that are suggested from this study are as follows: Firstly, we need to operate the Spcial Account for Traffic Facilities. Secondly, the investment should be focused on the facilities and districts in needs. Thirdly, PFI (private finance initiative) policy should be aimed at investing for the highly economic-valued projects.

Manufacturing today is becoming increasingly competitive. If a company is to exist and successfully compete, it must pay very careful attention to production management, total quality assurance and total proactive maintenance issues. Overall machine performance, repair efficiency, system level utilization, productivity and quality of output need to be optimized as possible. To accomplish that objective, the behavior of manufacturing equipment and systems need to be monitored and measured continuously if it is possible. Then early warning of possible failure should be generated and proacted on that type of the situation to improve overall operation performance of manufacturing environment. In this paper, Proactive maintenance framework using performance-based reliability structure as enabler technology is proposed. Its paradigm enables one to maximize system through-put and product quality as well as resources in the performance domain. In the case of inadequate knowledge of the failure mechanics, this empirical modeling concept along with performance degradation knowledge can serve as an important product and process improvement tool. The real-time framework extension to proposed framework uses on-line performance information and is capable of projecting the remaining useful period.
