Resistance spot welding is commonly used for welding products of high quality because of clean welding and short w welding-time. But. conventional spot welders bring about the depreciation of welding products, iuespective of dynamic r resistance characteristics during welding time. This paper discussed dynamic resistance database implementation in t terms of welding performance improvement. On different welding conditions, we compared dynamic resistance, r respectively, about pure iron and Sn-Pb alloy on Copper. Also, it investigated the relation of tensile shear strength and d dynamic resistance in welded workpiece.

Applying Ismailov and Rossi (2018), I newly construct the Korea FX uncertainty based on the density distribution of historical forecast errors. This uncertainty index properly captures the rare but significant events in the Korean currency market and provides information distinct from other uncertainty measures in recent studies. I show that 1) FX uncertainty arising from unexpected depreciation has a stronger impact on Korea-U.S. exchange rates and that 2) macro variables, such as capital flows or interest rate differentials, have predictive ability regarding Korea FX uncertainty for short horizons. These findings enable us to predict the events of sudden currency crashes and understand the Korea-U.S. exchange rate dynamics.

This paper reviews four different kinds of currency crisis models proposed to explain the Korean crisis of 1997 to examine which model is more relevant to explain the Korean crisis of 2008. According to the author's investigation, the 'Frenkel-Neftci' cycle is more relevant model to interpret the Korean crisis of 2008. In 2008, spreads opened due to, first, high interest rate policy by the Korean government aimed to suppress real estate price increase, and, second, the expectation about exchange rate appreciation, and thirdly stock market returns after recovering the crisis. Then the international capital market catastrophe due to the subprime crises produced the sudden change of expectation of the market participants. Huge capital outflows resulted from the credit crunch in the international capital markets, and the possibility of exchange rate depreciation by the Korean government to promote exports in the course of the global recession.

This paper offers a comprehensive view of international risk sharing and of related policy issues from the perspective of the European Union. The traditional analyses contemplate three risk-sharing channels: the capital markets channel (through cross border portfolio investments), international transfers and the credit markets channel (via savings). Comparative analyses reveal that, on average, about 80% of the shock remains unsmoothed in Europe while only about 18% of the shock is transmitted to consumers within the US. From aggregated figures, there is space for improving, particularly, the cross-border investments channel in Europe. In this sense, the completion of the Banking and Capital Markets Union are expected to boost risk sharing across European member states. We also review new additional issues usually not contemplated by the traditional literature as depreciation, migration and the role of sovereigns and two new additional channels recently considered in the literature: government consumption and the real exchange rate. Finally, we also examine recent analysis related to the geographic distribution of risk sharing.

Hospital costing has generally been using ABC costing method. However, based on increase of expensive equipment, the fixed cost is increased in the hospital industry. The most common equipment industry are using building block costing method for depreciation and equipment management costing elements. Additionally it presents three options that may be considered to be supported by the IT system to find the most appropriate alternative.

The tax lease scheme for ships is an advanced ship financing tool that generates tax benefits through accelerated depreciation of capital allowances and transferring them to the ship operator (leasee) via reductions in rental payments. The scheme was introduced by Japan in 1978 and by France in 1998 to support their shipping and shipbuilding industries. The size of tax benefits varies by country depending on the depreciation rate for ships, corporate tax rate, and the tax system on profits from the sale of ship. This study uses a virtual model of the Korean tax lease scheme for ships based on the French tax lease scheme. The size of tax benefits is calculated and compared to those in the French and Japanese tax lease schemes. According to the analysis, the size of the tax benefit was approximately 19% for France, 14% for Japan, and 12% for Korea. This is differentiated by the country's depreciation rate and corporate tax rate, which have the greatest impact on the size of tax benefits. For the Korean virtual model, if the tax benefits are distributed by the operator and the investor at the rate of 75:25, the operator is expected to enjoy tax benefits equivalent to about 9% of the ship price and the investor to enjoy 3%. Despite limited information and data regarding the tax lease scheme for ships, this study was the first attempt in Korea to design a virtual model of the Korean tax lease scheme based on some predictable assumptions. Therefore, a group of shipping, financing, and legal experts will follow up on more professional and practical reviews of the model in the near future. Hence, this study will serve as a small contribution to the early introduction of the Korean tax lease scheme for ships.

The paper aims to establish the characteristics of the Korean firms' R&D investment and to estimate the private rate of return to R&D investment. For the empirical analysis, a balanced panel data is constructed with 695 firms on 8 year observations. The panel data enables to characterize R&D investment of the Korean firms, which is mostly conformed to the 'stylized facts' of R&D investment that found in the previous studies on foreign firms. Klette model was used to estimate the private rate of return on R&D investment and depreciation rate of R&D capital. The paper estimates that the rate of return on R&D investment is 10.5% on average or 16.4% on median for the whole industry whereas manufacturing firms show 10.4% on average or 16.4% on median. The depreciation rate was estimated about 32.9% for whole industry, where it ranges from the minimum 11.6% for metal industry and 49.5% for services. The median estimate of the rate of return for R&D investment of Korean firms is roughly two times higher than real interest rates for the same period, which implies that R&D investment allows sizable rent in addition to the opportunity cost of capital investment.

There is the need of regulating chestnut production because of being expected with chestnut trees cultivation farmhouses to be in a difficult situation by means of FTA negotiation promotion hereafter in Korea. And this study is aim to establish compensation criteria and plan for depreciation of income of farmers who take part in chestnut production regulation. We surveyed one hundred and thirty three among chestnut trees cultivation farmhouses in chief producing districts Kyung-nam, Jeon-nam and Chung-nam in Korea. As the result of this study, this study showed compensation criteria and plans for depreciation of income for farmers's participate in chestnut production regulation and showed criteria for closing chestnut old tree orchard and working process of cutting chestnut old tree. Procedures in closing chestnut old tree orchard in a day per hecta were felling operation and crude manufacture of thirty trees per one man, five forklains in loading and unloading chestnut log from a truck and building of workroad, the two number of assistance persons in loading and unloading chestnut log from a truck, the 6.94 trucks in carrying chestnut log. After farmers close chestnut trees orchard, government cost of old trees cuts and net income decrease for 3 years in case of planting trees for landscape and environment preservation.

The purpose of this study is to examine the impacts of newspaper contents producers' role stress and burnout on their job satisfaction. For this, a survey was performed, of which the subjects were selected out of a great number of journalists employed in several newspapers. Finally, a total of 229 completed questionnaires were used for statistical inspections, such as correlation analysis and multivariate regression analysis. The results of this study can be summarized as follows: First, it is demonstrated that, the more stress journalists have with respect to role ambiguity, repetitive duties, and role conflict, which are three of the four factors causing role stress, they are less likely to have job satisfaction. However, role overload, the remaining factor of role stress, is shown to have nothing to do with job satisfaction despite it actually causes job stress most. Also, it is ascertained that role ambiguity among the aforementioned four factors of job stress has the most positive effect on job satisfaction in comparison. Second, burnout is shown to have negative correlation with job satisfaction. That is, it is identified that, the more burnout such as emotional exhaustions, depersonalization, and depreciation of personal accomplishment journalists perceive, they are less likely to have job satisfaction. In addition, it is become clear that depreciation of personal accomplishment, among the factors of burnout, has the strongest impact on job satisfaction.
