In e-learning industry which represents the convergence of IT and education, the standard of e-learning content development cost has been calculated according to the guideline or standard of existing similar industries without considering the characteristics of the industry until today. The absence of contents development cost standard related to e-learning has been recognized as one of the most difficulties in e-learning industry. The calculation of the content development cost without reflecting the characteristics of e-learning industry has bad effects such as the degradation of content quality and development of e-learning industry, and the growth obstruction of them. This paper suggest a standard of development cost for e-learning content development considering the characteristics of e-learning industry. We analyse current problems and the characteristics in e-learning industry, and define the development cost standard. We propose the methodology for developing e-learning industry and for contributing quality improvement of e-learning content.

The purpose of this study was to examine the relationships among mother's psychological characteristics(self-esteem, self-efficacy, and depression), parenting related factors(maternal parenting stress and mother's knowledge on infant development), maternal parenting style, and two-year-old infants' development. The participants consisted of 1735 mothers and their two-year old infants selected from a sample of the 3rd Panel Study of Korean Children(PSKC) by the Korea Institute of Child Care and Education(KICCE), conducted in 2010. Data were analyzed by means of a Structural Equation Model(SEM) to identify the structure and relationships among the various factors. The significance of direct and indirect effects to test the mediating effect of maternal parenting style were identified via bootstrapping. The results indicated that maternal parenting style most definitely mediated the relationship among the mother's psychological characteristics(self-esteem and self-efficacy), parenting related factors(maternal parenting stress and mother's knowledge on Infant development) and the development of their two-year-old infants.

With the development of the electronics industry and widespread supply of many different electrical appliances, the factors of the electrical fires are also diversified. For this reason, the fuse, safety-critical component, needs accurate and stable operating characteristics for preventing various fire factor, and also needs various operating characteristics. Especially when the all electrical resistance are dropped by internal short of circuit, high current inrushes and makes the fire. In order to prevent this, very fast acting fuses should be applied. However, existing very fast acting characteristics fuse has less wire dimension of element Ag100% metal than that of fast acting fuse, and it is made of plating with low melting point metals, so it satisfy very fast acting but it can't satisfy durability and safety. For this reason, in this study, through the analyzing fusing characteristics of Ag-Cu alloy composition, the new alloy composition, which implement to very fast acting fuse without decrease of fuse elements dimension, is suggested. And this study classify the operating characteristics changes, a resistance change, and the rated current of the fuse in the overall composition change of Ag-Cu alloying. and it can be utilized for designing fuse.

As the problem of lowering the efficiency of urban services in small and medium-sized cities in the non-metropolitan area intensifies, the necessity of developing a railway station area is being emphasized to form a compressed urban space through regional bases. Although major station areas in large cities are being developed in the form of complex, the analysis of the development location characteristics of the small and medium-sized city station areas is insufficient. The purpose of this study is to analyze the characteristics of development project conditions and potential demand in the high-speed rail station areas across the country, identify the differences in locational characteristics according to the type of city, such as 'metropolitan city', 'large city in non-metropolitan city', 'medium and small city in non-metropolitan city', and find out the appropriate development method. As a result of the analysis, it was analyzed that the 'metropolitan area metropolitan area' has high potential demand and poor business conditions. On the other hand, in the case of the non-metropolitan area, it was analyzed that the 'small and medium-sized city station area' has good business conditions and low potential demand characteristics, and the 'large city station area' has intermediate characteristics. This suggests the need for different development methods in the development of metropolitan and small and medium-sized city station areas. The analysis results of this study show that it is desirable to encourage private participation in large-scale metropolitan station areas, which require large-scale input, to maximize potential demand, and to encourage private participation through public-led projects based on favorable business conditions or development based on regional characteristics.

This study intended to discover the communicative characteristics of libraries, such as locality, communality, interactivity, and organic vitality, and measure as to whether the components constituting them were appropriate, and based on the research results, it was intended to establish the role of public libraries based on communicative characteristics. As a result of the study, it finally turned out that the libraries had the four communicative characteristics of 'locality', 'communality', 'interactivity', and 'organic vitality'. The four communicative characteristics may be classified into 16 factors and 63 detailed factors accordingly. Examining the characteristics of library communication, first, locality means that local residents create and maintain the identity of a social, historical, and cultural locality while sharing the space of a library. In the library, the users can receive local life information or create a cultural identity of the locality through communication between the users. Second, communality is a fundamental factor in forming a community of local residents and represents the characteristics of a group formed based on place and geographical characteristics, culture and belief system, and interests. Third, interactivity refers to a kind of behavior in which users interact with other users, information providers, and books and information in the library to give and receive influence. The actions in which two or more objects share knowledge, thoughts, emotions, and opinions may be seen as being accomplished through interaction. Lastly, organic vitality means seeking the continuous maintenance and development of the community, and creating a lasting characteristic even in the changing environment of the library.
