The objectives of this study are to amend of the Small Stream Maintenance Act. In general, small streams have diverse ecological and social characteristics because they are extensively formed across watersheds over time. However, small streams in Korea have been significantly degraded primarily because of human disturbances including stream maintenance activities. Especially, covered streams are majority problem in the Small Stream Maintenance. In order to improve this problem, the Small Stream Maintenance Act be amended to the Small Stream Management Act.

The main purpose of this study was to demonstrate the most common characteristics of the small and medium system integration companies in performing IT projects. In this study, 388 auditing reports on the 194 IT projects which were carried out by the small and medium size manufacturers from 2006 to 2009 were employed and surveyed. This survey revealed that the schedule management was the most neglected item in the project management area, the test planning and action was the most neglected item in the development and coding area, and the manual preparation for users and operators was the most neglected item in the operation and maintenance area. Consequently these three most neglected items were considered as the most common characteristics of the small and medium system integration companies in performing IT projects.

As new small scale LFG (landfill gas) energy project model which can improve economic feasibility limited due to the economy of scale, LFG-Microturbine combined heat and power system with $CO_2$ fertilization into greenhouses was proposed and investigated including basic design process prior to the system installation at Gwang-ju metro sanitary landfill. The system features $CH_4$ enrichment for stable microturbine operation, reduction of compressor power consumption and low CO emission, and $CO_2$ supplement into greenhouse for enhancement plant growth. From many other researches, high $CO_2$ concentration was found to enhance $CO_2$ assimilation (also known as photosynthesis reaction) which converts $CO_2$ and $H_2O$ to sugar using light energy. For small scale landfills which produce LFG under $3\;m^3$/min, among currently available prime movers, microturbine is the most suitable power generation system and its low electric efficiency can be improved with heat recovery. Besides, since its exhaust gas contains very low level of harmful contaminants to plant growth such as NOx, CO and SOx, microturbine exhaust gas is a suitable and economically advantageous $CO_2$ source for $CO_2$ fertilization in greenhouse. The LFG-Microturbine combined heat and power generation system with $CO_2$ fertilization into greenhouse gas to enhance plant growth is technologically and economically feasible and improves economical feasibility compared to other small scale LFG energy project model.

The building below standard scales to be built only by constructive report to authorities. Construction law 8 illustrates that supervision should be deployed in all the construction sites at the building which is found to have more than 3 floors and also to have more than loom of total squares in especially outside area of city plan zone. Such a small construction is have a important and the most basic meaning. Many problems were found to occur in all the constructive places which were out of the limit of this law. The construction sites were found to be controlled by public official's visiting without supervisors and designers of architecture. Technique of construction in architecture was found to be not different from that of 1980. The security of employees in construction on sites has a serious problem. Because of choosing ail the materials of the building without a reasonable point. All the building were found to have a law material about inside and outside aspects. The purpose of this study are to examine existing law about a small project and than to analyze the situation of constructive control through questionnaires and interviews with all the supervisors. Based on the data base of engineers who had a great experience in construction sites, The purpose of this study is also to suggest and advise the method of controlling all the items in architecture through on and off line.

Recently, the government is trying to change the paradigm of occupational safety by enforcing the entire revision of the Industrial Safety and Health Act and the Punishment of Serious Accidents Act with the goal of reducing the occupational accident and death rate by half. In particular, small-scale workplaces with less than 50 employees or less than 100 million won have difficulties in establishing a safety and health management system due to lack of safety and health management competency and lack of will of business owners. Therefore, this study attempted to identify problems and suggest improvement measures through an expert survey on the overall business area of the small business safety and health technology support project, which is one of the government's policies.

Missing data is one of the common problems in building analysis or prediction models using software project data. Missing imputation methods are known to be more effective missing data handling method than deleting methods in small software project data. While K nearest neighbor imputation is a proper missing imputation method in the software project data, it cannot use non-missing information of incomplete project instances. In this paper, we propose an approach to missing data imputation for numerical software project data by combining K nearest neighbor and maximum likelihood estimation; we also extend the average absolute error measure by normalization for accurate evaluation. Our approach overcomes the limitation of K nearest neighbor imputation and outperforms on our real data sets.

The revised "Software Industry Promotion Law" has been effective from 2013. This law is to be basis of the domestic public information sector and increases the opportunities for small and medium-sized firms in participating the public IT projects. The shortcomings of this law may be the increase of the risk and the decrease of quality of projects. These suggest that the competencies of project manager (PM) s are critical. Also, in general, an SI (System Integration) project is a one that provides a customer with a customer-tailored system for system integration. Particularly, in an SI project involved in a public institution or a large corporation, the ripple effect of success or failure of a project is becoming greater as the system requires higher cost and more time due to high complexity and large scale. One of the solutions to address these problems is to investigate the competencies of a PM. Thus, in this paper, we derived the major competencies using the RGT (Repertory Grid Technique) and categorized the resultant constructs using the content analysis. In addition, we analyzed the level of importance of competencies by applying the AHP (Analytic Hierarchy Process). The conclusion was that Problem-solving Skill and Leadership were the most important competencies of a project manager.

This study empirically examined different patterns of collaborative R&D project with their key success factors(KSFs), using data from 82 projects in the Korean electronic parts industry. The patterns of R&D collaboration were categorized into 4 types by two criteria development motive(technology Push/market pull) and Project initiator (focal firm/partner). The bivariate relationships revealed that project characteristics (technological complexity, market uncertainty), management characteristics (participation in project formulation), problem solving characteristics(problem solving performance of the focal firm, users active role in problem solving, active role of university or research institute in problem solving) and success rates appear to be different among four types of collaboration. Each type of collaborative R&D projects also had different KSFs. The KSFs of type 1 (technology Push and focal firm initiation), for instance, include the strategic importance of the project, focal firms share of cost, active role of university or research institute in problem solving, while those of type 4(market pull and customer initiation) cover reliability of partner relationship, a time at partners involvement, information sharing. The findings suggest that the different contingencies brought different patterns and KSFs of collaborative R&D project, since different information, resources, and partners roles were needed to successfully implement the projects according to development motive and project initiator Finally, managerial, policy, and theoretical implications for the collaborative R&D activities in the Korean electronics parts industry were discussed, based on empirical results of this study.
