In the point of view, this study aims to examine the life of remarriaged old people after divorce and bereavement. therefore, the purpose of this study is to increase the understanding of married couple's relationship and remarriage in old age and help old people who want to be abused about their remarriage as a coping response of lire for widowhood in old aged. the subject were 14 old people who married over 53 years old bereavement and divorce residing in Chonju, Chonbuk and they had indepth interviews. 1. Most of subject would married with help of matchmaker under the consent a children and relative 2. The main motivation of remarriage was lone lies, however, for men being taken care and for women economic security were also important. 3. Premarriage experience seemed to help spouse adjustment between couples. 4. They matintained close relationship with there biological children. 5. There show a tendency to the bereavement woman remarriage life was happier than divorce woman. 6. When one of the couple had regular income, little economic conflict was there. In most case, wifes were younger than husband and economic stability after husband's death was their main concern and when the husband didn't show definite will to inherit asset to his wife, conflict got bigger.

The current study analyzed the impacts of fiscal decentralization (FD) on the economic stability of Pakistan. This study used time series data from 1981 to 2017. The collected data was first passed through the unit root analysis. ARDL estimation techniques were employed to scrutinize the data where long-run associations were tested through Wald F-statistics. The long-run estimates were extracted by applying Ordinary Least Square, and error correction mechanisms were employed to find the speed of adjustment for disequilibria between the long and the short run. Wald F-statistics confirmed the existence of long-run cointegration. Long-run elasticities suggested that fiscal decentralization because of limited institutional capabilities of provincial governments failed in bringing stability in the economy of Pakistan. Similarly, transparency issues and misspecification of projects hinder the outcome of investment to stabilize the economy. High service payments on debt cut the amount that can be used for skills improvements and destabilize the economy. High Population growth puts pressure on infrastructure and reduces production capacity, ultimately destabilizing the economy by increasing unemployment and inflation. Based on these findings, the government is suggested to improve the institutional capacity of lower governments for the desired outcome of power devolution.

Since the Paris Agreement, countries around the world have been planning to introduce RE100, CF100 and the Carbon Border Adjustment Mechanism to achieve carbon neutrality. In these policies, advanced and renewable energy sources such as wind power, solar power and geothermal heat are recognized as core power resources to deal with climate change. The contribution of this study is that the wind power industry was added to the 33 major categories in the 2015 regional input-output table, published by the Bank of Korea, expanding the total to 34 sectors. As a result, the spillover effects of the 2.4 GW offshore wind power project are as follows. First, the domestic direct and indirect production effect amounts to 25.0 trillion won. Among these, Jeonbuk's production effect reaches 6.3 trillion won. Second, the domestic direct and indirect value-added effect is 9.3 trillion won, of which the Jeonbuk region's value-added effect is 2.4 trillion won. Third, the domestic direct and indirect employment effect is 450,643 people, of which the Jeonbuk region's employment effect is 125,085 people. The limitation of regional input-output analysis is that an increase in input due to inflation can lead to an increase in output, which may lead to a discrepancy from economic reality.

In determining the horizontal positions, economic, speedy, and accurate analytical adjustment methods have studied and developed for a long time. From now on, the adjustment methods using both angles and distances are expected because the development of more precise instruments, E.D.M, and electronic total station provide us with more advantages than the conventional measurement system. The objective of this paper is to study the characteristics of triangulation, trilateration, and combination method due to change of the weight factor of angles, distances, azimuthes, and control point coordinates of combined geodetic network. The results of this study show that combined method is more accurate and effective than other methods in case of combined geodetic network as the other simple networks.

The purpose of this paper is to model price formation and analyze demand structures for fishes under the restriction of Korean fisheries regulations. This study suggests the model that the price of fish is formed by its quantity, expenditure, and habit persistence. In economic literature, such a fishery market demand is called the inverse demand with dynamic habit persistence. Based upon a static differential price formation model, the paper has generalized it dynamically incorporating habit persistence effects. The empirical results show that all the species have values less than one and (-) sign of price flexibilities, thus being price inflexible. The estimated habit adjustment coefficients are significant at the level of 1%. Especially, TAC species have the smaller values of them than those of other main fish species. The contribution and results are summarized as follows. First, the fishery market demand has a strong dynamic effects from habit persistence. Second, the fishery market demand structure could be analyzed in a way different from the ordinary demand analysis, which is based upon price flexibility, scale flexibility, and cross adjustment flexibility. Third, the limitation of this paper is that it ignores the increasing stock effects by catching restrictions, thus raising consumers' benefit in the future.

This paper empirically tests the theory that labor demand elasticity of unionized firms would be smaller than that of nonunionized firms, using the Korean firms' panel data for 1990-2009. The major findings are the following: First, the estimates of labor demand elasticity of unionized firms are in the range of 0.34-0.49, less than a half of those of nonunionized firms, hence supporting the theory. Second, the unionized firms are more rigid in dynamic adjustment of employment than nonunionized firms. Finally, there are no significant differences between unionized and nonunionized firms in the elasticity of substitution.

This paper examines whether me effects of product demand shocks on employment are different between unionized and non-unionized firms, using new firm-level longitudinal data in Korea over the period 1997~2004. The estimation result shows that the effects of both negative and positive demand shocks on employment are smaller in unionized firms than in non-unionized firms. The result implies that unions appear to provide their members with job stability in response to negative demand shocks, while playing a very limited role in employment determination in response to positive demand shocks leading to employment expansion.

In order to predict the moldability of a injection molded part, a simulation of filling is needed. Especially when short shot is predicted by CAE simulation in the filling stage, there are mainly three ways to solve the problem. Modification of gate and runner, replacement of plastic resin, and adjustment of process conditions are the main ways. Among them, adjustment of process conditions is the most economic way in the cost and time since the mold doesn\\`t need t be modified at all. But it is difficult to adjust the process conditions appropriately in no times since it requires an empirical knowledge of injection molding. In this paper, a fuzzy neural network(FNN) based upon injection molding process is proposed to evaluate moldability in filling stage and also to solve the problem in case of short shot. An adequate mold temperature is generated through the fuzzy neural network where fill time and melt temperature are taken into considerations because process conditions affect each other.

This study analyzes the structure of the variations In the domestic bank earnings and examines their dynamic features by estimating the short-run response and the long-run adjustment Process after the changes in financial market variables. A system of the equations for the bank stock price index and KOSPI is formulated to utilize the whole information in the market and simultaneously estimated to identify the relationships between the market variables and the bank earnings. Since the bank stock price is found to be responsive to changes in none of the market variables in the short run, while being relatively responsive to dollar exchange rate and business state, It implies that a good economic conditions and a stable foreign exchange rate should be maintained to Improve the level of the stock price In the long run. In addition, the dynamic structure of the responses of the bank stock price index and KOSPI to the initial changes in the market variable are compared and anlayzed. The response of the bank stock price appears to take much longer in adjusting to the long-run eouilibrium level than that of KOSPI. As a result, the cumulative response of the bank stock price index over time is found much bigger than that of HOSPI.

Published employment statistics do not provide enough information about the relationship of unemployment and economic and business conditions. This study investigates long-run equilibrium relations and short-run adjustment process of unemployment and discouraged unemployment with major price variables in the business coincident and lagging framework. Speed of adjustment from short-run disequilibrium to long-run equilibrium is found to be relatively faster for discouraged unemployment that appears more responsive to changes in most of explanatory variables. Discouraged unemployment is found to reflect reality and suggested to be a more meaningful statistical index.
