최근 WTO 협약에 의한 기술개방, 국가간 기술사 상호인증, 이공계 교육 활성화 및 선진화에 능동적으로 대처할 수 있도록 기술사의 전문성을 확보할 수 있는 법 제도적 기반의 마련이 시급하다. 이를 위해서는 정확한 기술사의 인력수급 전망을 조사하여야 하며, 그 결과에 따라 고급 기술자로서의 기술사 인력 육성 및 활용방안이 수립되어야 한다. 우수 기술사의 육성은 그 가치가 결정되는 적정한 수급을 바탕으로 이루어진다. 따라서 본 연구는 현행 제도에 의한 기술사 인력 수급의 문제점을 분석하고, 향후 기술사 인력의 수급을 조정하기 위해 제도적인 측면의 개선방안을 제시하고자 한다. 본 연구의 결과는 향후 선진수준의 기술사 인력수급체계 구축은 물론 효율적이고 일관된 기술사 양성 및 활용 체계구축에 이용될 것이다. 아울러 시장 개방과 관련 기술사간 국제 통용성 확보 등 우리기술의 국제무대 진출체제 확립을 위한 정부 정책의 기초 자료로 활용될 것이다.

1963년 우수 기술인력의 확보를 위해 기술사제도를 도입한 후, 주택건설 200만호 건설 등 건설경기의 활성화로 인한 건설기술자의 수급불균형 등을 해결하기 위하여 학력 및 경력기술자를 건설기술자로 인정하는 제도를 1995년에 도입하였다. 이러한 인정기술자제도의 도입으로 건설기술자는 양적으로 크게 증가하여 2000년 이후 건설기술자의 심각한 공급초과가 발생하였고, 이에 따라 최고 기술자격인 기술사의 활용에 있어 심각한 폐해가 일어나고 있다. 정부는 최근 WTO협약에 의한 기술개방, 국가간 상호인증 등과 관련한 기술사의 전문성을 확보할 수 있는 법 ${\cdot}$ 제도적 기반을 마련하고 있다. 이러한 제도적 측면을 반영한, 정확한 기술사의 인력수급예측을 통하여 기술사 인력 수급의 문제점을 분석하고, 향후 기술사 인력의 수급을 조정하기 위해 제도적인 측면의 개선방안을 제시하고자 한다. 본 연구의 결과는 향후 선진수준의 기술사 인력수급체계 구축은 물론 효율적이고 일관된 기술사 양성 및 활용 체제 구축에 이용될 수 있을 것이다.

Though electricity consumption amount in industry has been increased gradually, corresponding power supply show symptoms of marginal point. Importance of demand-side management from large-industries has also been raised. This paper deals with induction motor, which is one of representative examples of heavy electricity consumption utilities, to analyze potential technical capability, economic feasibility from consumers' viewpoint and demand-side management feasibility from nation-wide perspective. Nation-wide economic feasibility analysis was done through California test, which has been used as demand-side management evaluation model. This paper also describes limitation of existing high efficiency induction motor in terms of contribution to demand-side management and utilizes premium motor to calculate demand-side management contribution level and economic feasibility evaluation. Likewise, this paper emphasizes the efficiency improvement of induction motor and analyzes how much premium motor related technologies can contribute to demand-side management.

국내외 건설규모가 축소됨에 따라 건설기술인력의 신규 인력채용기피 및 수급상의 불균형 등으로 인해 대학졸업자의 취업이 극히 어려운 현상을 보이고 있다. 이러한 상황에서, 최근 대학졸업자의 취업률이 $35\%$미만으로 나타나는 등 건설기술인력의 실업대책이 중요한 사안으로 부상하였으나, 건설기술인력의 과잉문제를 해결하기 위한 범정부 차원의 종합적인 대책이 미흡하였다. 또한 대학졸업자의 교육성과에 있어서도 다양화, 첨단화되고 있는 건설산업 현장에서의 수요에도 부합되지 못하고 있다. 이에 본고에서는 $2003{\~}2008$년간의 건설기술인력의 수급예측을 하였고, 과잉공급된 건설기술인력의 수급효율화 방안을 마련하기 위해 SOC 투자확대, 미취업 건설기술인력의 IT분야 유도, 해외진출 확대 등 건설기술인력의 고용창출방안과 더불어, 건설관련 학과의 탄력적 운영, 기업수요에 대응한 대학교육 등 양적 질적인 측면을 동시에 고려한 건설기술 과잉인력의 수급대책을 마련하였다.

This paper is developed to Energy Balance Flow show the flow of total energy resource be used nationally. The Energy Balance Flow is applicable of demand management factor through the analysis of foreign energy model of supply and demand and energy statistic data in the country. This study is based on and developed to Energy system management model is able to appraisal efficient of energy cost cutting, CO2 emission reduction and Energy saving at the national level calculated effect reached amount of primary energy to change of energy flow followed application of demand side management factor is able to appraisal quantitatively at the total energy to model of demand and supply.

This paper estimated the demand and supply of physicians for oriental medicine for the period of $2009{\sim}2019$. Two equation models were used in the estimation of manpower. In 2004, the total number of physicians of oriental medicine was amounted to 13,662 registered and 10,532 available in clinical practice, respectively. According to estimates in the study, overall excess supply of physician manpower in oriental medicine was expected in the period, such as $5,300{\sim}5,700$ persons in 2009 and $900{\sim}1,700$ persons in 2019. However, the excess supply would be mitigated after 2019 mainly due to an increase in demand for oriental medical services. Specially, opening medical service market to overseas could be an exogenous variable in physician supply. An alternative manpower policy for oriental medical doctors is needed in a way of controlling oversupply.

This study presents the empirical results of comparing several demand forecasting methods for Supply Chain Management(SCM). Adaptive exponential smoothing using change detection statistics (Jun) is compared with Trigg and Leach's adaptive methods and SAS time series forecasting systems using weekly SCM demand data. The results show that Jun's method is superior to others in terms of one-step-ahead forecast error and eight-step-ahead forecast error. Based on the results, we conclude that the forecasting performance of SCM solution can be improved by the proposed adaptive forecasting method.

This study proposes an optimal operational policy for a green supply chain (GSC) where a retailer pays an incentive for collection of used products from customers and determines the optimal order quantity of a single product under uncertainty in product demand. A manufacturer produces the optimal order quantity of product using recyclable parts with acceptable quality levels and covers a part of the retailer's incentive from the recycled parts. Here, two scenarios for the product demand are assumed as: the distribution of product demand is known, and only both mean and variance are known. This paper develops mathematical models to find how order quantity, collection incentive of used products and lower limit of quality level for recycling affect the expected profits of each member and the whole supply chain under both a decentralized GSC (DGSC) and an integrated GSC (IGSC). The analysis numerically compares the results under DGSC with those under IGSC for each scenario of product demand. Also, the effect of the quality of the recyclable parts on the optimal decisions is shown. Moreover, supply chain coordination to shift the optimal decisions of IGSC is discussed based on: I) profit ratio, II) Nash bargaining solution, and III) Combination of (I) and (II).

Supply chain management (SCM) has been regarded as one of the most critical issues in the current business environment. Moreover, supply chain partnerships between suppliers and buyers in SCM have had a significant impact on supply chain performance. In this paper, we conduct a quantitative analysis for supplier-buyer's profit sharing and pricing policies based on supply chain partnerships. For this purpose, we assume that a two echelon supply chain with a single supplier and a single buyer is given and the buyer faces deterministic demand which is not only a function of buyer's selling price, but also strictly decreasing, concave, and twice differentiable function. Then we will prove the following. Firstly, without supply chain partnerships, there exist supplier and buyer's selling prices per unit such that their total profits are maximized, under the assumption that buyer's order quantity is exactly equal to the demand buyer faced. Secondly, buyer's selling price per unit which maximizes supply chain's total profit with supply chain partnerships is lower than buyer's selling price per unit which maximizes buyer's total profit without supply chain partnerships. Thirdly, given supplier's selling price per unit. buyer's total profit without supply chain part nerships is greater than that with supply chain partnerships, whereas the opposite case happens for supplier's total profit. Finally, there exists supplier's selling price per unit which makes the maximum total profits for both supplier and buyer with supply chain partnerships greater than those obtained for any given supplier's selling price per unit without supply chain partnerships.

The most important task in Korean dairy industry is to keep the seasonal and annual balance of raw milk supply and demand. Too much surplus milk supply which causes dumping sale of market milk makes dairy industries get in trouble of management, and eventually affects to farmers and consumers economically. As balancing of supply and demand is so important in the fee economic market system, the adaption of the quota system of milk production and seasonal price differentiation has been recommended very often as a method of controlling the milk supply and demand. However, this recommendation did not go through successfully due to the strong objection of dairy farmers. Recently, the voice of consumer's requirement for safer and more hygienic, and high protein, low fat level dairy product is getting stronger. By knowledge of this kind changes, quality improvement in nutrients and hygiene is the most positive way to expand the volume of milk consumption. To meet the consumer's demand, therefore, it is necessary to revise the level of milk fat content and the hygienic grading system for the payment system of raw milk.
