The objective of this study is to analyze the performance and farmer's awareness on the large-scale environment-friendly agricultural districts (LEAD). For this, we survey 393 farmers who cultivate in the 14 LEAD. Most of farmers aware a necessity of LEAD project. They have a higher awareness and practical use on the 'production facilities and equipments for environment-friendly agricultural materials' and 'resource recovery center of crop-animal farming'. The spread and consciousness on the environment-friendly agriculture increase before LEAD project. Also the environment-friendly agricultural areas and incomes slightly increase. The results of this study show that the LEAD project need a modification in to response to change of agricultural issues and customer's needs.

The Purpose of this paper is to suggest sustainable strategies of the project for developing large-scale environment-friendly agricultural districts (LSEAD). This study used assessment 3 indicators, efficiency, impact and sustainability of environment-friendly agricultural certification area and farmers, management situations of crop-livestock circulation center, educations for environment-friendly farming, changes of farmer's income and so on. This project has contributed to develop environment- friendly agriculture and model of LSEAD. And for sustainable development of LSEAD, it is necessary to renovate crop-livestock circulation centers, promote organic farming of resource-circulation type, converse to non-pesticide or organic farming of low pesticide one, do active marketing activities, establish a governance system of business projects and so forth.

This paper aims to consider an overall benefit-duration optimization (OBDO) problem for the sake of maximizing owner's economic benefits, whilst considering influences of schedule compression incurred opportunity income on the profitability of a large-scale construction project. Unlike previous schedule optimization models and techniques that have focused on project duration or cost minimization, with greater weight on contractors' interests, OBDO facilitates owner's economic benefits through overall benefit-duration optimization. In this paper, the objective function of OBDO model is formulated. An example is illustrated to prove the feasibility and practicability of the overall benefit-duration optimization problem. The significance of employing OBDO model and future research work are also described.

U-City means the high-tech city that applied ubiquitous technology and information communication technology. U-City aims to intensify urban competitiveness and to improve the quality of residents' life through efficient management of the urban. Currently, 77 U-City projects is underway. The each project cost and scale estimate is not clear in the absence of the U-Service Standardization Model. So, many of the project are trouble about making a production the proper number of U-Service or the cost of project. The excessive service construction is reflected on the construction costs, which leads to the rise of sales price and passes onto the executor of a project as a burden of the project costs, and the problem of the delay of the change-over occurs due to supporting the operation costs for the operation of the constructed service and the demand for additional installation of facilities between a local autonomous entity and the executor of a project. In this paper, we suggested the U-Services Construction Standardization Methods and proposed the standardization services guideline of crime prevention services. U-City services in the future are able to maintain the consistency of the system through the utilization of the proposed standard model. As a result, the U-City project's pre-estimated cost and scale can be extracted.

최근 국가 연구개발 과제의 성과물에 대한 실용화 또는 상업화 강화가 중요한 이슈로 떠오르고 있으며, 기술 실용화 관점에서 연구개발 과제를 체계적으로 관리할 수 있는 지원 도구에 대한 필요성이 높아지고 있다. 기존의 기술준비수준 모델은 기초 연구부터 실용화까지의 기술 개발 수준을 9개의 수준으로 나누어 각각의 수준에 대한 기준을 제시해 줌으로써 과제 관리를 위한 유용한 도구로 활용되어 왔다. 그러나 이 모델은 기술준비수준의 평가가 전문가에 의해 이루어져야 하며 구체적인 평가지표도 제시되어 있지 않기 때문에 다수의 과제로 구성된 국가 연구개발 사업에 적용하기에는 어려움이 있다. 따라서 본 연구는 델파이 기법을 활용하여 기존의 기술준비수준 모델을 대규모 국가 연구개발 과제에 적용할 수 있도록 각 수준에 대한 정의와 각 수준의 달성 여부를 결정하는 평가지표를 제시하였다. 본 연구에서 제시된 기술준비 수준 모델은 각 수준에 맞는 구체적인 평가기준을 제공함으로 대규모 국가 기술개발 과제의 연구개발에서 실용화까지의 전 과정을 관리하기 위한 도구로 적절하게 활용될 수 있을 것으로 기대한다.

In Korea, traditional doenjang is manufactured using the conventional method at home and by small-scale enterprises. Because this age-old process depends on natural inoculation of various microorganisms, it is difficult to reproduce or maintain consistency in the final product quality across batches. Moreover, doenjang occasionally prepared by this method raises safety concerns related to aflatoxin, biogenic amine, and Bacillus cereus contamination. To develop starters that can be conveniently used at home or in small industry settings for the manufacturing of safe and flavor-improved doenjang, autochthonous microbe starters were developed in dried forms as ready-to-use starters. Each starter powder prepared by heat- or freeze-drying methods remained stable even after 24-week storage. These ready- to-use starter powders were successfully applied to lab-scale fermentation for the production of safe and flavor-improved doenjang. We believe that these ready-to-use starter powders will benefit small-scale enterprises in the manufacturing of doenjang of good reproducible quality.

In this work, risks in EPC project for overseas power plant projects are analyzed and risk management methods are suggested to reduce cost and to shorten time. 79% of risks occurred in the engineering phase for S project located in South-East Asia. The impact scales of risks on major project objectives which are cost, time, scope, and quality are analyzed as 3.5, 3.8, 2.7, and 3.7, respectively. The level of impact scales is very similar to each other except the impact scale of scope. The risk management methods suggested in this study have to be applied at the appropriate time to manage risks effectively. After that, risks are managed continuously by monitoring.

The Purpose of this paper is to analysis on farmer's awareness and satisfaction level of the project for developing large-scale environment-friendly agricultural districts (LSEAD). To analysis farmer's awareness and satisfaction level, a series of farm household surveys were conducted on farmers, take part in the project for developing LSEAD. The sample size of the survey is 80 respectively. As a survey result, awareness and practical use of facilities & equipment shows a little different outcome. Satisfaction level of the project for developing LSEAD is summarized as follows. Influence on disposal of livestock excretions and farmer's consciousness change appears 4.47 and spreading environment-friendly agriculture 4.44, distribution of environment-friendly agricultural product 4.33, and demand of environment-friendly agricultural materials 4.04. In order to sustainable development of LSEAD, a governance system should be established.

The government and the Korea Occupational safety & Health Agency have continuously carried out safety activities such as supervision, inspection, technical guidance and financial support in order to reduce safety accidents at the construction site. However, the number of disasters at construction sites is increasing every year. So analyze the results of the supervision and inspection of the Ministry of Employment and Labor, the projects related to the small-scale construction work of the Safety and Health Corporation, and the technical guidance project of the disaster prevention technology guidance organization. It is also necessary to establish an improvement plan for the disaster reduction of the small-scale construction work site for this project.
