Construction of power plants and T&D facilities is so difficult because of the civil complaints and the additional cost according to the concerning field conditions. Therefore, various researches and methods have been considered to get solutions in the demand side and energy storage systems have been in the spotlight because of the various functions such as peak shaving, load shifting, and power system stabilizing, and so on. Residential small size batteries are considered in this paper and the economic analysis is carried out to evaluate the reasonable subsidy levels for the deployment of energy storage systems. Various economic parties are considered to find reasonable subsidy level comparing each other, which parties consist of utilities, participants and non-participants in general. The evaluation is based on California Standard Practice Test and the results are able to be used as subsidy guidelines.

The external diseconomy is hampering sustainable development of the city logistics sector. Burdens on urban environment imposed by the city logistics industry have been put in the spotlight. Based on the principle of Life Cycle Analysis, the comprehensive environment impact for city logistics systems is measured. Firstly, with the city logistics service chain as a whole, its business processes and their interactions with environment are analyzed. In total four types of major environment impact categories are determined. Secondly, case study is made on three city logistics operators located in Jing-Jin-Ji region of China with different business modes, respectively self-operation mode, joint distribution mode and the $3^{rd}$ Party Logistics or 3PL mode. Through analysis of energy consumption and emissions for various business processes, their comprehensive environmental impact values are finally obtained. Thirdly, horizontally comparative analysis is carried out to these three modes of the urban logistics distribution systems. Results show the advantages of the 3PL and the joint distribution modes in developing greener urban logistics distribution. Future research avenues and policy suggestions are proposed finally.

As a promising alternative for the traditional educational system, the cyber education is in the spotlight of both educators and computer scientists. There are many advantages of online education to the students and to the institution such as easy and random accessibility, low cost, saving spaces in the institutions, and so on. or a successful online education, some important factors would be considered in constructing cyber lectures. The purposes of this paper are to investigate students'viewpoints, called factors, of the cyber class and analyze these factors to be an effective cyber class. Once factors are identified, we trace the change of the student assessments on the identified factors during the class. Using these factors, we also examine if there are any differences on the assessment of the cyber class according to student background, such as gender. major, and class.

The intrusion prevention system solution is receiving the spotlight as the next generation security system. It is anticipated that the system will form a very active security market both domestically and overseas. Moreover, quality evaluation proving successful inspection of merchandises is required of domestic businesses seeking to operate in the international market, and general users also prefer those that have successfully passed inspection. This study has constructed a security quality evaluation model for intrusion prevention system by deriving and analyzing security quality evaluation items required by an intrusion prevention system solution and by classifying them in detail. The derived quality evaluation model will play an important role of assessing and improving the quality of intrusion prevention system.

Recently, the satellite image is getting large spotlight as a way for getting necessary information of urban planning and management, but the satellite image is only used to explain the status or basemap instead of paper map in urban planning works. From this study we derived the detail indexes to fix the boundary of urban improvement project, for measuring these indexes used with satellite image and GIS. the linkage of GIS and satellite image let us to catch the indexes and contribute to improvement type deciding in Urban Improvement Project.

UCC comes into the spotlight as keyword to lead forward web business with appearance of web 2.0 that has characteristic of 'participation, opening and sharing'. Despite continuous magnification of UCC's influence by spread of prosumer that consuming public participates actively in production and development of new platform, there is no clear business model of UCC. So, inside and outside of the country industry is trying various effort to break this situation. As basis research for establishment business model of UCC, this paper wished to examine the prospects of development by analyzed present condition of UCC service. That is, it drew problems of UCC service after examine concept and type of UCC, direction technology development and profit model through analyzed foreign countries and domestic example of UCC's service. It wished to watch the development direction of UCC service from that.

Purpose: This study focused on SNS, which has been in the spotlight as a marketing tool as the number of people using SNS, to find out about the relationship between the characteristics of airline SNS marketing and the impact on brand attitude and purchasing intention. It will also identify the relationship between each factor and, in conclusion, identify the influence of SNS characteristics as marketing tools of airlines and provide direction and theoretical implications so that they can be used as effective marketing tools based on this. Research design, data: Airline SNS characteristics factors were derived from three main components: interactivity, entertainment, and convenience, four hypotheses were set up, and the SPSS Win 18.0 program and AMOS 22.0 were used to analyze the relationship between factors in a total of 333 questionnaires. Results: The airline's successful SNS marketing directly affects the airline's brand image and airline's brand attitude, and a good brand image forms a positive brand attitude for consumers and also suggests that this can lead to purchasing intentions. Conclusions: Airlines that want to successfully market SNS should pay attention to SNS characteristics and consider them in-depth, and pay attention to SNS as an important marketing tool.

Digital is the main topic of 21C design. Experts analyzed that pop art and related cultural products are becoming popular as digital generations of twenties to forties are centered of new art culture. This survey is to suggest the differentiated jewelry products which are out of the existing products as combining the embodiment of various colors by using celebrities who are taken kindly to and the lenticular which can be image converted through an optical illusion. As public's living standard is getting improved, design elements would come into the spotlight. Therefore, this research is expected to work as the part of an epoch-making design in the jewelry industry by extending the design field.

Architects may evaluate building models to see how a building will shadow itself and its neighbors at various times. A heliodon, a tilt-table which is a machine that imitates the rotation and orbit of the Earth, helps architects wanting to analyze patterns of shadow patch, passive solar heating options, site solar panels, or control solar heat gain. The heliodon swivels in three directions for setting latitude, season, and time of day. Using the device, an architect first clamps a model to the tabletop, then turns the table to the coordinates of interest. Usually, the winter and summer solstices receive strong attention, for they represent extreme cases, A more recent installation at a university adds to its heliodon a set of lamps to recreate the illumination level and more accurate patterns of shadow patch. The table holds the building model at various angles to a spotlight, which mounts in the pole. The set of scale model measurement describes the validity of various electric lamps as an artificial sun to approximate the sun's parallel rays, helping designers to distinguish between illuminated areas in and around a building and those regions falling in the shadows.
