This is a paper to understand the economic effects of the measurement standards by translog cost function. The data, as of the end of 1998, are from a survey of 514 firms in Korean industry. The analysis is compared to that of 1992 data analysis to check the trend. There are a little differences on the estimated coefficients, but there is no basic difference on trend of economic effects. The Investment on measurement standards have been contributed positively on the major managerial indicators such as productivity, profit, and so on.

The introduction of a ubiquitous environment has realized commercial ubiquitous services in various industrial fields and government area. The central and/or local governments are demanding an appropriate investment evaluation model for ubiquitous service. Thus, this study develops and suggests an evaluation model for ubiquitous service by reflecting its characteristic of promoting public good, as well as its broad ripple effect on people. The investment evaluation model for ubiquitous service suggested by this study is based on Cost Benefit Analysis Method. Especially, the 'Benefit' is analyzed in two aspects; 'Economic Benefit', which shows the benefit that ubiquitous service providers to the overall local economy, and; 'Financial Benefit', which shows the profit of individual investors participating in the introduction of ubiquitous service. The investment evaluation model for ubiquitous service suggested by this study can be used by the central and/or local government during their evaluation for investment before introducing a ubiquitous service. Also, when introducing a ubiquitous service in public field, the model can be used to support the decision making of private businesses for investment. Finally, it can be used to promote and inform the expected benefits of introducing a ubiquitous service to local residents.

Because land based aquaculture is restricted by high investment per rearing volume and control cost, good management planning is important in Land-based aquaculture system case. In this paper master production planning was made to decide the number of rearing, production schedule and efficient allocation of water resources considering biological and economic condition. The purpose of this article is to build the mathematical decision making model that finds the value of decision variable to maximize profit under the constraints. Stocking and harvesting decisions that are made by master production planning are affected by the price system, feed cost, labour cost, power cost and investment cost. To solve the proposed mathematical model, heuristic search algorithm is proposed. The model Input variables are (1) the fish price (2) the fish growth rate (3) critical standing corp (4) labour cost (5) power cost (6) feed coefficient (7) fixed cost. The model outputs are (1) number of rearing fish (2) sales price (3) efficient allocation of water pool.

본 연구에서는 1998년부터 2008년까지 우리나라 거래소에 상장되어 있는 기업들을 대상으로 기업의 내적인 투자기회, 외부금융의존도 및 타인자본비용이 기업의 자본투자의사결정에 미치는 영향을 분석하였다. 기업의 투자의사결정은 거시적인 경제정책에서도 영향을 받지만 기업 자체가 처한 상황인 영업경쟁력, 자본시장 이용조건, 자본비용 등의 요인에 의해서도 영향을 받다. 본 연구에서는 선행연구에서 초점이 되었던 법인세율이 기업의 자본투자에 미치는 영향을 통제한 상태에서 기업의 투자결정요인을 기업적 측면에서 분석하였다. 분석결과는 다음과 같다. 첫째, 기업의 투자기회는 자본투자에 양(+)의 영향을 미치는 것으로 나타나 기업의 영업 경쟁력인 투자기회가 많을수록 기업의 투자는 촉진되는 것으로 나타났다. 그러나 이러한 영향은 외부금융의존도가 높을수록 약화되며, 투자기회가 자본투자에 미치는 영향이 타인자본비용이 높을수록 약화되는 것으로 나타났다. 둘째, 기업의 외부금융의존도와 자본투자는 양(+)의 상관관계가 있는 것으로 나타나 외부금융의존도가 높은 기업의 경영자들이 자본투자에 적극적임을 암시한다. 그러나 타인자본비용이 높아질수록 투자기회가 자본투자에 미치는 영향의 정도는 낮아져 투자기회가 많다고 할지라도 타인자본비용이 높은 경우에는 자본투자에 저해요소가 됨을 암시한다. 셋째, 기업의 타인자본비용이 높을수록 자본투자는 낮아지는 것으로 나타났으며, 유가증권 시장 표본의 경우 투자기회가 자본투자에 미치는 영향은 타인자본비용이 높을수록 작아지는 것으로 나타났다. 본 연구에서는 기업의 내적인 요소가 자본투자에 미치는 영향을 분석하였다는 점에서 의의가 있으며, 향후에는 자본투자에 영향을 미치는 다양한 요인들을 밝혀내려는 시도가 필요할 것으로 보인다.

Using data from the 2007 SCF, this study examined the use of information source for investment decisions of elderly consumers. The results indicated that many elderly consumers (about 88%) involved savings /investment decisions. The elderly used 'Experts' (39.48%) as a major information source for their investment decisions, followed by 'Friends' (24.18%). The results of the multinomial logit analysis suggested that the perceived value, the cost for search, knowledge, risk and some of the demographic factors were significantly related to the choice of the information sources for investments by elderly consumers.

Most of Korean broiler farms are constructed with vinyl houses. Such types of broiler farms might be cheaper in terms of cost, but poor in terms of environment condition. According to enlargement of broiler farm size, high value production systems or automatic facilities are introduced in this field. However, investment may not always guarantee the profit of the management. Therefore, it is necessary to undertake the investment analysis before decision making for the investment. Under the assumption that 870 Pyoung(≒$3.3㎡) of a broiler farm within 1,740 Pyoung(≒3.3㎡) of land is built with the producing capacity of 50,000 heads of chicken in a time. The total investment is calculated to be 600 million won(1,000 won≒$1.1), and out of them 58.1% is provided by the owner, 31.6% from the government loan, 5.8% from government subsidy, and 5.3% from other agencies or banks. The expected profit of the broiler farm is 64.6 million won(1,000 won≒$1.1) per year. The IRR calculated is 0.0808 which means that the rate to profit of this project would be 8.1%. This also means that for this investment the interest rate of the capital provided should be less than 8.1% per year. Considering that the current opportunity cost of the own capital is 8.5% this project is not so attractive for those who is going to build broiler farms mainly with their own capital. In other words this project would not be profitable, unless the average interest rate of the loans provided for this project is less than 8.1% per year.

Quality is a critical competitive factor in today's environment because of the impact of quality on costs and delivery. Many companies regard quality as a key concept of company strategy in order to achieve the competitive edge. Measuring and reporting quality cost is the first step in quality management program. The supposition of quality cost model is that investment in prevention activities will bring rewards from reduced failure costs, and that further investment in prevention activities will show profits from reduced appraisal costs. In this study, the degree of quality cost deviation is conceptualized. This means a deviation between the ideal and present ranking in the amounts of quality cost categories. This study analysed that the effect of its deviation on quality management activity and performance variables. However, there are no difference in these variables. The major reason is that most of companies are endeavoring for quality management but operating quality cost system unsystematically. The review against a prevention and appraisal activity is necessary.

The purpose of this study is to suggest the improved methods for cost sharing in apartment remodeling projects. Case studies on apartment remodeling projects with different plan type were analyzed and compared. Cost sharing estimated by 'proportional rate method' shows similar results estimated by 'return on investment method' in case of similar area ratio of existing plan to remodeling plan. Otherwise cost sharing estimated by 'proportional rate method' shows great differences comparing the results estimated by 'return on investment method'. Although return on 'proportional rate method' is widely used, it is not proper to estimate cost sharing when each householder's contribution for the project varies, such as considerable differences area ratio of existing plan to remodeling plan. Improved cost sharing method is needed taking into account project contribution and characteristics.

본 연구는 패널자료(15개 시도의 20년간 자료)를 이용하여 홍수피해 비용과 복구비와의 상관관계에 대한 분석을 시도하였다. 패널 분석은 자료의 성격에 따라 고정효과모형 또는 확률효과모형을 사용하지만 본 분석은 두 모형을 함께 추정하였다. 예상대로 모든 변수들은 복구비와 정의 상관관계를 보였지만 사망자수와 이재민 수는 유의하지 않거나 오히려 음의 상관관계를 보이기도 하였다. 그리고 공공시설의 피해가 가장 중요한 인자였다. 무엇보다 중요한 것은 우리나라의 경우 복구비가 피해액이나 투자액에 비해 항상 높다는 것이다. 우리나라와는 반대로 일본의 경우 복구비가 가장 낮고 투자비가 가장 높다는 점을 미루어 볼 때 결국 적절한 투자가 향후 홍수피해는 물론 복구비도 낮출 수 있다는 점을 확인할 수 있었다.
