이 연구는 사유림의 영세성 극복과 경영활성화를 위해 국가정책사업(國家政策事業)으로 추진되고 있는 협업경영사업의 실태를 조사할 목적으로 수행되었다. 이러한 목적을 위해 협업체 관련 통계자료, 법규 및 문헌 자료들을 검토 및 분석하고, 협업체 관련 공무원과 실무자들을 대상으로 면담조사(面談調査)를 실시하였다. 또한 우편설문조사를 통해 협업체에 가입한 산주들의 협업체 운영실태에 대한 인식(認識) 현황(現況)을 조사하였다. 설문의 내용은 참여 산주들의 산림경영현황과 협업경영에 대한 일반적 태도를 중심으로 작성하였다. 조사결과 50% 이상의 응답자들이 임업경영에 대해 관심을 보이지 않고 있으며, 대다수 응답자들이 협업체의 협업경영 활동에 대해 긍정적인 인식을 지니지 못하고 있는 것으로 나타났다. 또한 기존 협업체 관련 통계자료들을 통해 전국의 협업체 수가 급속하게 증가하고 있음을 확인할 수 있었다. 그러나 협업체의 수적(數的) 증가(增加)는 개별 협업체에 대한 정부지원액의 감소를 야기(惹起)하여 오히려 경영여건을 악화시키고 있는 원인이 되고 있다. 이 외에도 기존의 협업경영 관련 법규들중 몇 가지 점들은 개별 협업체들의 발전에 부적합(不適合)한 것으로 지적되었다.

This study analysed the result of a survey answered by 120 technology teachers and 360 students from 357 middle schools in Seoul to find out the actual state of safety accidents during technology education activity course in the middle school class and safety awareness of the teachers and students. The result shows that many safety accidents happen during technology education activity course in the middle school class. However, most teachers and students have experienced safety accidents or dangerous situations more than once a year. Technology teachers had very low awareness on the states of retaining safety equipments. On the other hand, they were well aware of the importance of safety, including the actual states of safety education, knowledge of safety, and the will to join safety education. Therefore, safety awareness of technology teachers should be reinforced by the extension of safety training and the improvement of safe environments.

Subsequently in Korea product liability has been introduced. The position of consumers for defective products have been disadvantageous. Defective products should be broght under the law. Then, while consumers would be largely protected, a producer would take the heavy responsibility by law, Therefore, a producer would not be able to take countermeasures for product liability. Object of this paper to investigate and analyze the actual state of management for product liability in advanced countries, and to join it with our quality management system.

This paper describes a new method for enhancing the accuracy of network analysis applications in energy management systems. Topology processing, state estimation, power flow analysis, and contingency analysis play a key factor in the stable and reliable operation of power systems. In this respect, the aim of topology processing is to provide the electrical buses and the electrical islands with the actual state of the power system as input data. The results of topology processing is used to input of other applications. New method, which includes the topology error analysis based on inconsistency check, coherency check, bus mismatch check, and outaged device check is proposed to enhance the accuracy of network analysis. The proposed methodology is conducted by energy management systems and the Korean power systems have been utilized for the test systems.

This paper introduces a tool for predicting potential cost overrun during project execution and for quantifying the uncertainty on the expected project cost, which is occasionally changed by the unknown effects resulted from project's complications and unforeseen environments. The model proposed in this stuff is useful in diagnosing cost performance as a project progresses and in monitoring the changes of the uncertainty as indicators for a warning signal. This model is intended for the use by project managers who forecast the change of the uncertainty and its magnitude. The paper presents a mathematical approach for modifying the costs of incomplete work packages and project cost, and quantifying reduced uncertainties at a consistent confidence level as actual cost information of an ongoing project is obtained. Furthermore, this approach addresses the effects of actual informed data of completed work packages on the re-estimates of incomplete work packages and describes the impacts on the variation of the uncertainty for the expected project cost incorporating Multivariate Probabilistic Analysis (MPA) and Bayes' Theorem. For the illustration purpose, the Introduced model has employed an example construction project. The results are analyzed to demonstrate the use of the model and illustrate its capabilities.

Computer simulations designed to predict technical and financial returns of wind turbine installations are used to make informed investment decisions. These simulations used fixed values to represent real-world variables, while the actual projects can be highly uncertain, resulting in predictions that are less accurate and less useful. In this article, by modifying a popular wind power simulation sourced from the American Wind Energy Association to use Monte Carlo techniques in its calculations, the authors have proposed a way to improve simulation usability by producing probability distributions of likely outcomes, which can be used to draw broader, more useful conclusions about the simulated project.

Horizontal construction projects such as oil and gas pipeline projects typically involve repetitive-work activities with the same crew and equipment from one end of the project to the other. Repetitive scheduling also known as linear scheduling is known to have superior schedule management capabilities specifically for such horizontal construction projects. This study discusses on expanding the capabilities of repetitive scheduling to account for the variance in production rates and visual representation by developing an automated alignment based linear scheduling program for applying temporal and spatial changes in production rates. The study outlines a framework to apply changes in productions rates when and where they will occur along the horizontal alignment of the project and illustrates the complexity of construction through the time-location chart through a new linear scheduling model, Linear Scheduling Model with Varying Production Rates (LSM_VPR). The program uses empirically derived production rate equations with appropriate variables as an input at the appropriate time and location based on actual 750 mile natural gas liquids pipeline project starting in Wyoming and terminating in the center of Kansas. The study showed that the changes in production rates due to time and location resulted in a close approximation of the actual progress of work as compared to the planned progress and can be modeled for use in predicting future linear construction projects. LSM_VPR allows the scheduler to develop schedule durations based on minimal project information. The model also allows the scheduler to analyze the impact of various routes or start dates for construction and the corresponding impact on the schedule. In addition, the graphical format lets the construction team to visualize the obstacles in the project when and where they occur due to a new feature called the Activity Performance Index (API). This index is used to shade the linear scheduling chart by time and location with the variation in color indicating the variance in predicted production rate from the desired production rate.

This study intends to investigate the actual state and problems of Outlet, and the research consumer's perception of Outlet. It affords a effective way to get rid of inventories for manufacture and to economize and rational buying for consumer. Ultimately trying to find a effective managing method of Outlet for both manufacturers and consumers. The result about research the actual sate of Outlet, there are affluent assortment, generous amount of merchandise and high discount rate in Kuro-dong Outlet stores, but stores' location is scattered that makes shopping environment inconvenient. It is not good condition of assortment, quantity and freshness of merchandise in Mungung-dong Outlet stores, but close proximity between stores and fancy shopping place make convenient shopping possible. Multi-discount stores dilute the fundumental of Qutlet with poor quantity and assortment of merchandise make man choices possible for consumer, but discount rate is lower for high management cost. The result about research the consumer's perception of Outlet shows that consumer have enough interest in Outlet, and intention to continue shopping in Outlet. Therefore we can expect continuous growth of Outlet. Also consumer is satisfied with price and quality of merchandise, but they are not satisfied with assortment of merchandise, expecially poorness in sizes.
