This paper presents a maximum power point tracking without a current sensor for a small scale photovoltaic power system. The small scale photovoltaic power systems are used in parallel, and so the cost and the reliability are strongly demanded. In the proposed inverter, the current is controlled with open loop, and then the power of photovoltaic array is calculated by the equation using the voltage of the photovoltaic array. Therefore, the system can obtain the power by detecting only the voltage of the photovoltaic array. As a result, we may obtain the performance of the MPPT with a current sensor as well as with a current sensor.

Purpose: The small-scale environmental impact assessment system in Korea was introduced and implemented in August 2000, but it has a problem that it cannot guarantee implementation due to the large proportion of qualitative reduction measures for each evaluation item. Therefore, when preparing a small-scale environmental impact assessment, research was conducted on how to improve the existing simple listing-type reduction measures and qualitative evaluation standards to quantitative reduction measures and evaluation standards reflecting regional characteristics. Research design, data and methodology: The small-scale environmental impact assessment system in Korea was introduced and implemented in August 2000, but it has a problem that it cannot guarantee implementation due to the large proportion of qualitative reduction measures for each evaluation item. Therefore, when preparing a small-scale environmental impact assessment, research was conducted on how to improve the existing simple listing-type reduction measures and qualitative evaluation standards to quantitative reduction measures and evaluation standards reflecting regional characteristics. Results: As a result of the analysis of qualitative and quantitative factors, the arithmetic sum of the qualitative factors of the total six projects is 160, accounting for 80% of the total number of reduction measures, and the quantitative factors are 40, accounting for 20%. Among them, the number of qualitative reduction measures reached 97.4% for animal and plant items, and more than 90% for air quality, noise and vibration, and eco-friendly resource circulation items. Conclusions: Therefore, it is necessary to avoid establishing qualitative reduction measures and set quantitative measures as the basis, but to specify the specifications, size, and installation location related to the reduction measures, and to calculate the numerical reduction efficiency.

The two-dimensional incompressible flow of a linear viscoelastic fluid we considered in this research has rapidly oscillating initial conditions which contain both the large scale and small scale information. In order to grasp this double-scale phenomenon of the complex flow, a multiscale analysis method is developed based on the mathematical homogenization theory. For the incompressible flow of a linear viscoelastic Maxwell fluid, a well-posed multiscale system, including averaged equations and cell problems, is derived by employing the appropriate multiple scale asymptotic expansions to approximate the velocity, pressure and stress fields. And then, this multiscale system is solved numerically using the pseudospectral algorithm based on a time-splitting semi-implicit influence matrix method. The comparisons between the multiscale solutions and the direct numerical simulations demonstrate that the multiscale model not only captures large scale features accurately, but also reflects kinetic interactions between the large and small scale of the incompressible flow of a linear viscoelastic fluid.

The digital map version 2.0 is national base map which is used for frame work data, paper map making as well as geographic information system. National Geographic Institude has been research to make small scale digital map by using large scale digital map. NGI made from 25 1/5,000 digital maps to one 1/25,000 digital map ver 2.0 with map generalization system in 2003. However, they could not make 1/10,000 and l/50,000 digital map version 2.0 because of There is no portrayal on the scale 1/10,000 and 1/50,000 digital map in the existing regulations. therefore. We create the specification of the digital map on scale in order to make small scale digital map version 2.0 such as 1/10,000 and 1/50,000 scale.

Recently, industrial accidents rate has been gradually decreasing due to the development of safety management methods, but until now, the accident rate in the construction sector is higher than other industries. Large-scale construction sites are operating systematic safety systems to reduce industrial accidents. However, small and medium sized construction sites do not have systematic safety system and lack safety management ability, so that disaster is not reduced compared with large scale construction site. As a result, disaster prevention technology instruction system has been implemented to reduce the disasters of small and medium scale construction sites. However, in the case of a small construction site less than 2 billion won, there is little decrease in the accident rate, and in some cases, the accident rate increases. After the technical guidance system has been implemented, it is necessary to identify the performance and problems of implementation and to improve its effectiveness. In this study, we suggest the improvement plan to improve the efficiency of the technical guidance system by analyzing the problems and actual conditions of technical guidance operation in small and medium sized construction work sites.

The government introduced the technical proposal drafting system in September 2007, as a new method to stimulate technical competence among construction companies to require ingenuity, creativity, artistic sense, and high-level technology. However, an examination of instances has shown that this system has been applied only to large scale constructions worth 30 billion won or more, and not to small and medium constructions worth less than 30 billion won. This is because the evaluation criteria of the system is structured in a manner that makes it difficult to apply to small and medium constructions. This study presented methods to improve the evaluation factors, categories, and scoring scheme of the technical proposal creation system for medium to small scale constructions to be able to further apply the current system to small and medium constructions. The technical proposal evaluation criteria presented in this study was significant in that it enabled the technical proposal creation system that was mainly used for large scale constructions to be further applied to medium to small scale constructions. And it also contributes to the establishment and settlement of a new technical proposal tendering for medium to small scale constructions.

The intent of this study is to investigate the feasibility of small-scale developments in residential blocks in the city, and to propose development strategies and models. This research is done on the premises that large housing developments ignore the urban structure of its own quality, whitens on-lot-based multi-unit housing developments fail to maintain amenity and livability in residential blocks. For solving these shortcomings, this research proposes the possibility of small-scale housing development models as an alternative development system. And some residential blocks were selected as case sites and analyzed into typical block types, to support the proposal of pertinent development types. Each type was investigated and discussed in terms of development feasibility and proper development strategies. Finally, three development schemes are proposed as prototypical models for the best application in residential blocks.
