A number of companies are considering for merger and acquisition (M&A) as one of business strategies for their growth and survival. However, many of them do not create the synergy they had sought, and failed M&A, often result in negative outcomes in terms of productivity, market share, profitability and turnover of qualified employees. There have been numerous research studies conducted to analyze the factors that determine the success and failure of M&A, and it has been found that with the increasing dependence of many companies on information systems, post-M&A IS (information systems) integration success has a critical effect on the success of M&A. However, there have been very few studies on post-M&A IS integration success, and most have been restricted to integration of IS organizations or physical information systems. In order to conduct a comprehensive research on the factors that affect the success of post-M&A IS integration, this study surveyed preceding researches on not only information systems but also strategic management, economics, finance, HRM (human resource management) and organization management. Based on the findings, a comprehensive and integrated model of the influential factors on post-M&A IS integration has been proposed. The proposed model categorizes the factors into perspectives of M&A, strategy, organization, HRM and IS, and provides an empirical evaluation of each factor on the success of IS integration based on comparative case studies.

The aim of this paper is to describe a long-term trend toward earlier retirement and its reversal since 1985 in the United States, together with changes in socioeconomic conditions and social-policy programs which have contributed to this new development. The American people's recent propensity to retire at relatively younger ages was mainly a result of secular increase in individual wealth that had made it possible for them to enjoy higher standard of living without their participation in labor market activities at older ages. In addition to the introduction of compulsory retirement system, both social security retirement pension program and corporate pension system have also contributed significantly to the declining retirement age and its reversal around the mid-1980s. This paper pays full attention to the set of social policy programs which are currently being used to sustain the recent reversal in ages at retirement. The basic question to be raised here, however, is about whether or not the U. S. government will ave to continue to implement the social policies and programs used to discourage the elderly from retiring at relatively younger ages in the future. In this paper, it is argued that labor productivity growth and improvement in work attitude prior to retirement will help the elderly find little difficulties in having higher standard of living, despite their further lengthening of life expectancy at birth and post-retirement survival chances, the latter being often called the "third life". Most American people hope that the social-policy programs that have promoted early retirement will remain unchanged in the first part of the 21st century while they will put significant financial burden on their future descendants who have to work in the paid labor market. Taking this observation in consideration, this paper concludes that the U. S. government has to focus more on developing the programs that improve work propensity and labor productivity among the currently working-age population rather than continuing to implement the programs that sustain the recent reversal in retirement ages.ment ages.

청정에너지원의 수요가 증가함에 따라 에너지원의 공급로의 역할을 하는 강관의 수요가 증가하고 있다. 소재가공 기술의 발전과 함께 경량의 고장력 강재의 적용은 공급로의 역할을 하는 강관의 비용절감 및 자원의 효율적 이용 측면에서 지속적으로 연구 개발을 이어왔다. 이러한 추세에 따라 구조용 또는 라인파이프용 강관에서도 고장력 강재의 적용과 함께 고인성 그리고 용접성의 향상을 위한 다양한 라인파이프용 강재의 개발과 이의 적용이 그간 활발히 진행되어왔다. 용도상 반드시 필요한 특성인 고장력, 고인성, 용접성 등 외에도 다양한 강재의 사용에 따른 제조공정상 즉 용접공정에서 발생될 수 있는 용접부의 기계적 특성 변화에 대한 특성 연구 및 기술 연구가 계속 되어왔다. 주로 강관을 생산하는데 쓰이는 ERW (Electric Resistance Welding) 공정에서도 이러한 문제점을 해결하기 위해 많은 연구가 진행되고 있다. ERW는 높은 생산성과 낮은 제조비용의 장점을 가지고 있으나 용접 후 용접부의 기계적 특성 감소로 인한 단점이 있다. 때문에 기계적 특성향상을 위해 최적의 용접조건에 대해 연구해야 할 필요가 있다. 본 연구에서는 4가지 합금강관의 ERW 용접시 용접 입열량의 변화와 용접부의 후열처리를 통한 미세조직의 변화와 기계적 특성에 대해서 고찰하였다. 4강종 시편의 미세조직을 OM, SEM을 통한 분석 이후 인장시험 및 경도시험 등을 통해 기계적 특성을 평가하였다. 대부분의 시편에서 입열량의 증가에 따라 Ferrite 분율이 증가하였고 용접중앙부의 Ferrite 양이 용접경계부 보다 많았다. Ferrite 집중부의 분포가 극명하게 관찰되었던 DP780 (적정) 강종과 미세하게나마 Ferrite 집중부가 존재하였던 K55 (과소, 과대) 강종에서 나란히 경도 하락 현상이 관찰되었다. 이는 강종마다 고유의 Ceq, 합금 중 Mn 농도, 입열량 등에 의한 복합적인 이유 때문으로 판단된다. 탄소가 0.3~0.4 wt% 함유된 중탄소강인 S45C, K55의 경우 용접중앙부와 용접경계부의 페라이트 분율 차이가 큰 것을 알 수 있었다. 이는 용접시 열에 의한 탈탄현상으로 인해 나타나는 현상으로 판단된다.

This study intended to provide basic data required in establishing policies for improving the forestry management and the compensation standard for the loss from non-timber forest products by examining the cost of cultivating key medicinal herbs and the earnings from them to analyze the income. According to the income analysis on the cultivation of medicinal herbs, the average annual income per unit area of Adenophora triphylla var. japonica Hara was the highest as it recorded 14,233,000 won/10a and was followed by Pleuropterus multiflorus TURCZ. which recorded 4,121,000 won/10a, Gastrodia elata Blume 3,766,000 won/10a, Epimedium koreanum Nakai 3,537,000 won/10a, Atractylodes ovata (Thunb.) DC. 2,655,000 won/10a, Aralia continentalis Kitagawat 1,048,000 won/10a, Paeonia lactiflora Pallas 1,025,000 won/10a, and Bupleurum falcatum L. 919,000 won/10a. Compared with the income from major nuts and fruits analyzed in 2014, the average annual income per unit area for medicinal herbs was relatively higher. For Adenophora triphylla var. japonica Hara and Aralia continentalis Kitagawat, soots are used for food and the roots for medicine, it appears that it can become a new income source for the farming and mountain villages. Meanwhile, the price for Paeonia lactiflora Pallas is dropping due to Chinese imports, and also damage to the income from other medicinal herbs due to Chinese imports is expected with the implementation of Korea-China FTA in the future.

We have seen a sharp increase in the utilization rate of medical services since the launch of Nation Health Insurance system in 1989. However, the market share of oriental medicine in the Korean health sector has been gradually diminished mainly due to low insurance coverage and high price. Especially high price as an entry barrier to oriental medical services has played a major role in decreasing market share. This paper investigated the effects of price discount on the financial condition and market share of oriental medical institutions. Microeconomic theory and multiple regression analysis were used as a methodology in testing the alternative hypothesis: price discount of enveloped herb drug will result in increases in both the revenue and market share of oriental medical institutions. Data was collected from the statistical yearbook and sample survey. The price elasticity of demand for enveloped herb drug was estimated at 5.8 during 1987-1995 period, which means that a 1% decrease in price will bring about a 5.8% increase in the utilization of oriental medical services. The empirical result shows that a drastic price discount for the enveloped herb drug will eventually improve the financial status of the oriental medical institutions and enlarge the market share of oriental medicine in the Korean health care sector.

The long-term imbalances between supply and demand in office market can weaken urban growth since excessive supply of offices led to office market instability and excessive demand of offices weakens growth of urban industry. Recently, there have been a lot of new large-scale supplies, which increased volatility in Seoul office market. Nevertheless, new supply of Seoul office has not been fully examined. Given this, the focus of this article was on confirming the influences of profitability, replacement cost, and demand on new office supplies in Seoul. In examining those influences, another focus was on their relative influences over time. For these purposes, we analyzed quarterly data of Seoul office market between 2003 and 2015 using a vector error correction model (VECM). As a result, in terms of the influences on the current new supply, the impact of supply before the first quarter was negative, while that of office employment before the first quarter was positive. Also, that of interest rate before the second quarter was positive, while those of cap rate before the first quarter and cap rate before the second quarter were negative. Based on the findings, it is suggested that prediction models on Seoul offices need to be developed considering the influences of profitability, replacement cost, and demand on new office supplies in Seoul.

The objectives of this study were to assess implementation on tariff quotas and tariff cuts committed in the WTO as result of Uruguay Round(UR) negotiations and to examine impacts of reductions in agricultural protection agreed in the UR on major non-timber forest products markets. The implementation of WTO Agreement on Agriculture was analysed based on the relevant data and statistics. The impacts of implementation on tariff cuts and tariff quotas on non-timber forest products markets were estimated by using supply and demand elasticities from previous studies and data on production, consumption and trade after UR. The quantities of Chestnut, Pine nut and Jujube imported by the system of tariff quota did not exceed the committed quotas over the five years from 1995 to 1999. The current level of applied rates on imports of non-timber products is much lower than that of bound rates, which will be maintained until the year 2004. It is estimated that increase in imports after UR reduced prices and that reduction in prices led to decrease in expenditure and to increase in consumer surplus. It is estimated, however, that production level significantly decreased due to rise in imports and that the negative effects on production exceeded positive effects on consumption. Exports of most non-timber forest products decreased after UR even though non-timber forest products could gain access to the export markets at the lower tariffs as a result of UR.

In general, quantity results of empirical analysis using model shows how much big performance policy has. Therefore this is useful to evaluate a policy. This paper composed macro economic model based on Bank of Korea's quarterly model and annual model, that estimates performance of overseas oil and gas development project to Korean economy in aspect of quantity. In this model, we estimated each effect in real GDP, current account, unemployment rate, CPI and exchange rate carried by recovered amount from overseas oil and gas development project. The recovered amount was evaluated in currency coming from oil and gas acquired from overseas oil and gas development project. Macro economic model of this paper benchmarked macro model composed by Bank of Korea(1997, 2004, 2012). We reviewed model robustness using statistical suitability of each equation and historical simulation for from 1994 to 2011. The recovered amount of overseas oil and gas development project has positive effect in every macro economic index except CPI and exchange rate. Economic effect to macro economic index become bigger with time because the recovered amount of overseas oil and gas development project are increasing until now. Although empirical results of economic effects in every year from the recovered amount of overseas oil and gas development project are different, as of 2011, empirical results showed that the recovered amount of overseas oil and gas development project increase 2.226% and 0.401% in current account and real GDP respectively. And it also decrease 0.489%p in unemployment rate. Exchange rate to US dollars also decrease in amount of 0.379%.

The government has been operating residential improvement projects through the "Act on the Maintenance and Improvement of Urban Areas and Dwelling Conditions for Residents" as a type of a remedial measure for deteriorated residential areas. However, in recent years, the residential improvement projects have experienced difficulties due to the effects of various factors including the slowdown in economic growth. After observing the depression in a number of projects, various studies have been carried out to investigate the causality and improve the promotion of the residential improvement projects. In the trend of research, this study aims to analyze the effects of land and building characteristics on the improvement projects of Busan Metropolitan City. The dependent variables of the study represent different phases of improvement project as specified in the "Act on the Maintenance and Improvement of Urban Areas and Dwelling Conditions for Residents". The independent variables represent land and building characteristics which refer to the criteria used in the designation process of maintenance area according to the act. The empirical analysis uses the ordered logit model. The results from the analysis suggest that geographical condition, factors related to the number of union members, factors related to the parcel price and condition of a location have impact on the promotion of the improvement project. The results of the analysis show that majority of the factors are related to the economic feasibility of the projects. Residential improvement project is a part of urban planning projects that rehabilitates deteriorated residential environment, and it is closely associated with the quality of life of public. Accordingly, we hope that such projects are reasonable and take effective approach to those with urgent needs rather than to focus on profitability. Also, potential administrative and economical loss should be avoided by taking necessary planning measures in advance.
