The purpose of this study evaluates a feasibility and economical efficiency of new renewable energy. According as weather change is serious problem now days, every people make attention to the reduction of greenhouse gas. The revitalization of new renewable energy creates the variety of energy source, stability of energy supply and reduction of greenhouse gas. In this study evaluates a feasibility and economical efficiency from new renewable energy of various photo voltaics, wind power, small hydro and biogas. Feasibility does in standard of technical characteristic, politic support, marketability, establishment present condition and development aim. Economical efficiency does in standard of developmental unit cost, utilization factor, equipment life, politic support cost, interest ratio. The results of this study were as follows photo voltaics, wind, small hydropower, biogas in order feasibility is high. Developmental unit cost, utilization factor, equipment life, politic support cost and analyzed the relationship of interest ratio fluctuation and economical efficiency. From all new renewable energy the utilization factor most is important in economical efficiency but necessary utilization factor is difficult because environmental problem.

Most manufacturing enterprises create CAD data as a result of the product/part design process; however, the CAD data is being utilized only for production activities. Besides the processes directly related to manufacturing such as design and production, the CAD data is an important resource that can be used in variety of services (e.g., catalog production and production manuals) for manufacturing enterprises. This study proposes a software platform that can support a wide range of services for manufacturing companies in an efficient and productive way. The software platform was designed based on the functions identified by requirement analysis. The platform consists of four layers: data model layer to manage relevant data; library layer and common function layer to configure services; and application layer to install and run the software. Finally, this study evaluates the validity of the proposed platform architecture by applying it to the digital catalog system.

Recently, the role of community in public design has become important. However, the design process often places only emphasis on the 'agreement' of the community. As a result, the process was forced to collect opinions from the community only passively. Also, a process that only focuses on the formation of an agreement is likely to provoke confrontations and conflicts between those who support and oppose it. In the end, persuasion by the opposing residents is more important than decision-making by the whole community. Therefore, it has recently been paying attention to 'decision-making' that values a variety of things, not 'agreement formation'. Because various values of the community are valued and process is more important than result, 'decision-making' is different from 'agreement formation'. South Korea is also paying attention to public design, where community decision-making is central. Therefore, it is very necessary to develop a methodology that can support community decision making. In Jeju, the community's decision-making support methodology was devised for urban regeneration. The purpose of this study is to examine the characteristics of this methodology and to reveal its potential and challenge as a decision-supporting methodology.

Stock movement is difficult to predict because it has dynamic characteristics and is influenced by many factors. Even so, there are some approaches to predict stock price movements, namely technical analysis, fundamental analysis, and sentiment analysis. Many researches have tried to predict stock price movement by utilizing these analysis techniques. However, the results obtained are varied and inconsistent depending on the variables and object used. This is because stock price movement is influenced by a variety of factors, and it is likely that those studies did not cover all of them. One of which is that no research considers the use of fundamental analysis in terms of currency exchange rates and the use of foreign stock price index movement related to the technical analysis. This research aims to predict stock price movements in Indonesia based on sentiment analysis, technical analysis, and fundamental analysis using Support Vector Machine. The result obtained has a prediction accuracy rate of 65,33% on an average. The inclusion of currency exchange rate and foreign stock price index movement as a predictor in this research which can increase average prediction accuracy rate by 11.78% compared to the prediction without using these two variables which only results in average prediction accuracy rate of 53.55%.

Modern society has a tendency to raise fewer children. As a result, parents became more interested in their children's creative ways of thinking and began to look for new ways of teaching. The child care support center expects a positive effect by lending various toys and books to improve the physical, emotional and social characteristics of children and to help reduce household burden on parents. In this paper, we design and implement a rental return system to effectively utilize a toy library operated by the child care support center. The proposed system makes it easy for any user to search for items in any branch operated by the Child Care Support Center and to manage loan return records. The administrator can manage data such as loans, returns, and past due from the rental return processing system, and effectively operate the child care support center through statistics of data generated. Children are expected to be given a variety of entertainment cultures and cultural benefits to their families to ease the burden of parenting.

Recently, theservice field based on the location while expanding into a variety of business areas and have generated significant revenue. In particular, the map service provides a variety of information in conjunction with such public transport directions. Therefore, this study evaluated the map service, as one of the key technologies, StreetView and LoadView photographs of panoramic photograph-support service-modules that can be supported on smart phones. For this, purpose sensors were provided to allow smart phone users to easily publish panoramic photographs. The unnecessary parts could be removed from several photos and pictures using the design technology, and the naturalness of the connection could be maintained by applying the algorithm to handle a single photograph. Finally, a system to work with smartphone panoramic photographs was configured and designed to operate a smartphone application panoramic photograph for 6 months.
