The purpose of this study is to examine the residents' preference to community facilities in national rental apartment complexes. Twelve housing complexes were sampled and researched with questionnaire and field-surrey methods. The data from the questionnaire survey were processed with SPSS 14 and analyzed by regional group, size of complex, and arrangement plan of facilities. The complexes are located in two legions, Seoul and Gyounggi province. They were also sorted into three groups by size: less than 500 households, 500 to 1,000, and more than 1,000. Lastly, the complexes were categorized into three types: those where facilities are concentrated in or around a single building, dispersed into several places, and located in residential buildings. The results are as follows: Majority of the community facilities are established outdoor and, therefore, the indoor facilities are relatively more insufficient. Especially, there is a shortage of indoor gymnasium while the demand is increasing. It is partly because there is no regulatory guideline on indoor gym requirements in housing complexes. The resident satisfaction measurement shows significant comparison according to region and complex size. The level of satisfaction with garden/kitchen-garden, pond/fountain/streamlet is higher at the complexes in Gyunggi. The residents of larger complexes give positive feedback about spells facilities while those of smaller complexes are more satisfied with education-related facilities such as library and study. The measurement of resident needs shows significant comparison according to complex size and facility arrangement plan. The residents of smaller complexes are more in need of community facilities. In both regulatory standards and actual condition, community facilities are more insufficient at small complexes with less than 500 households.

As Internet usage is rapidly spreading, tasks that were only possible offline are now available in cyber space but at the same time, new security threats such as hacking and viruses have also increased. For that reason, Comprehensive and methodical information security systems are therefore required in enterprises and organizations. Consequently, the Information Security Management System certification system has been in effect in Korea since July 2001. As of December 2012, 130 enterprises have been certified, and more than 120 ISO27001 certifications have been issued. As such, since the introduction of the ISMS certification system in Korea, the demand for the certification has been steadily increasing, and it is now recognized as an integral part of maintaining the competitiveness in an enterprise. However, the qualitative aspects of certification regarding the effectiveness of ISMS have been continuously questioned by actual customers. In order to clarify the situation and remove such doubts, this study will substantiate the fact that development and certification of ISMS positively affect the business performance of enterprises so that they will recognize the effect of obtaining ISMS certification and eventually prevent security accidents and improve their business performance by developing ISMS.

The purpose of this study is to establish the one serving size of Korean Indigeneous Food. Serving size is necessary to make Nutrition Labeling which is required to export Korean food product especially to the United States of America. The basic data of 100 food items were collected through searching traditional and recent cookbooks. 4 industrial foodservices as noncommercial foodservice and 30 traditional ethnic restaurants and 12 gourmet restaurants in hotels as commercial foodservlce were explored to collect the data of actual serving size of each items. Moreover, experimental cooking and sensory evaluation by trained panels were conducted to assess quantity preference of selected food items. All data were rearranged through food type, that is, main dish, side dish, dessert and health food. One serving sizes showed wide variety according to the different menus that include selected food items. Therefore, means and ranges of serving size by four research methods were presented item by item. There were wide differences in intakes of main dishes, for example, noodles were around $50{\sim}100g$, cereals were 20 g, which means the one serving size can be differenciated by the food usage. In intakes of side dishes, average of side dishes were $20{\sim}30g$, but Kimches, the first traditional Korean food, were $30{\sim}50g$, and the other condiments, pepper paste and soy paste were $5{\sim}10g$. About desserts, liquid types were around 200 g, the other sugars were $10{\sim}20g$, the kind of teas were almost $2{\sim}3g$. The health foods-many kinds of that were Ginseng-were averaged 20 g; but dried mushrooms were around 2 g.

The aim of the study was to develop an objective measurement tool, which could measure radiation safety regulations as an advanced research to draw evidentiary conclusions for the rationalization of radiation safety regulations as organizations continuously increase consumption of radiation material. The survey was based on the contents of Vol 1~21 of US NRC NUREG 1556 (Consolidated Guidance About Materials Licenses) and material from the Nuclear Safety Act which was based on radiation safety managers who are responsible for about 10% of the domestic registered organizations for radiation usage. As a result of the analysis, 3 main causes were extracted based on 20 questions. Each causes were named as Cause 1: 'Radioactive Safety Regulations Requirements', Cause 2: 'Compatibility of Actual Safety Regulation', and Cause 3: 'RI/RG radiation Source Classification' respectively. The dispersal explanations of each causes were explained in total of 60.417% by 40.140% of Cause 1, 13.721% of Cause 2, and Cause 3 for 6.556% If radiation safety regulation standards are drawn using the radiation safety regulation measurement tool, which is suggested in this study, this could be not only comply with international standards but also could be used to propose a practical standard to domestic radiation safety managers.

This paper empirically analyzes specific characteristics of VOD users and their practical viewing patterns, using socio-demographic data of the current IPTV subscribers in combination with actual data of genre usage and payment. The findings revealed active viewing patterns of male, the unemployed, high earners and early adopters. In terms of preferences, households with large numbers of women prefer time shift contents, whereas households composed of more men or preschoolers prefer non-time shift contents. Likewise, the households that have more women or higher income had relatively a lot of experiences of purchasing time shift contents on one hand, but the households characterized by the larger numbers of family members or unemployed householder or young householder showed much willingness to pay premium contents on the other hand. Given the utilization of correct database, the findings offer useful information conducive to service promotion and marketing strategies to maximize VOD use in the practical dimension.
