The leaders such as The Robert Foundation of the U.S., Social Firms U.K., EMES European Research Network worldwide are groping for the survival strategies of social enterprises and of their developmental methods with the utilization of social capital. Along with the way the world economy goes on, this study is first of all to empirically analyze how the diversity and strength of network as independent variables work with the studies of the survival of enterprises of Granovetter Mark, Burt Ronald, Coleman James, Peter Witt, Andreas Schroeter, Christin Merz, Helen Haugh, mainly concerned with the increase in employment, the increment in sales, delegation of authorization as dependent variables and secondly it is to present a theoretical possibility of optimizing the development of social enterprises. The object of this study consists of 25 companies recommended by experts out of the current national 295 social enterprises in 2009 through the analysis of sources of SPSS 12.0, appropriateness, reliability, interrelation, etc; besides, hypotheses are proved by multiple regression analysis. A result of the investigation indicates that there is the necessity of network in all the processes of the survival of enterprises, the growth in employment, the increase in sales, delegation of authorization; especially, it suggests that it is necessary to manage, maintain and develop primary factors relating to a variety of networks to improve sales, and relating to the intensity of network for the survival of corporations. At last, I think that this study could be a help to the strategies of utilizing social capital in order for many companies or nonprofit social organizations in Korea to develop into constant enterprises.

This study conducted a regulatory impact analysis regarding the introduction of the Korean version of REACH(Registration, Evaluation and Authorization of Chemicals). The direct cost of the Korean REACH is estimated at a total of 101 billion Korean won over the 11 year period. The cost includes pre-registration, testing, registration, Chemical Safety Assessment(CSA) and Chemical Safety Report(CSR), evaluation, and the authorization costs of 15,223 chemical substances produced and imported more than 1 ton per year in Korea in 2006. With regard to the benefit, the only public health benefit is included in the estimation. Based on the available foreign and domestic data, this study estimated that the economic values of public health benefits are in the range of 33.2~138.6 billion Korean won if only the savings of the National Health Expenditures are considered and it reaches 203.9~1,640.3 billion Korean won if the willingness to pay(WTP) for disease prevention is included. This study proved that the Korean REACH passed the cost/benefit criteria. The benefit-cost ratio of the Korean REACH, however, is estimated to be lower than its EU counterpart. Thus it is suggested that a rigorous study to reduce the costs to industry be required before the Korean government introduces the Korean REACH.

This study analyzed high school informatics textbooks that were developed based on the 2015 Revised National Curriculum. Content analysis was adopted to analyze the organization system of the textbooks. Learning objectives were also analyzed according to Anderson's taxonomy of educational objectives. Through content analysis, it was revealed that the textbooks were composed of activities, differentiated learning, and small group learning to promote core competencies. The analysis of learning objectives of the textbooks showed that 'understanding' (41%), 'developing' (20%), and 'applying' (18%) were the three highest criteria in terms of cognitive processes; in terms of type of knowledge, conceptual knowledge accounts for the highest(45%), followed by procedural (32%), and factual (12%). Further methods to improve the textbook quality is proposed based on the results from this analysis.

The breeding work was initiated by utilizing two Japanese hybrids namely C135${\times}$N134 and N137${\times}$C146 along with two evolved Indian breeds, J14 and A24. The breed CSR16 which is characterized with marked larvae and white dumbbell cocoons was evolved from the Japanese hybrid C135${\times}$N134 by crossing with J14, while the breed CSR17 which is characterized with plain larvae and white oval cocoons was evolved from the Japanese hybrid N137${\times}$C146 by crossing with A24. The hybrid of these evolved breeds i.e., CSR16${\times}$CSR17 has shown superior over control hybrid $KA{\times}{NB_4}{D_2}$ and on par with the ruling hybrid of CSR2${\times}$CSR4. The hybrid CSR16${\times}$CSR17 was authorized during 1999 by Central Silk Board, Bangalore, Government of India for commercial exploitation during favourable months based on national level race authorization test.

As various measures of law observance obligations such as mandatory obligation of privacy impact assessment (PIA) for public institutions and authorization of information security management system (ISMS) are put into practice, increase in demand for information security consulting and securement of information security consultants are emerging as a major issue. The purpose of this study is to empirically investigate what core competencies information security consultants should possess and how much they actually possess them. By analyzing the differences in perception between practitioners and managers on core competencies, this study understands difference of views between the two groups and suggests ideas for cultivation of information security consultants.

Enzymatic hydrolysis of shark (Squatina oculata) cartilage (SC) was optimized by response surface methodology (RSM) for chondroitin sulfate (CS) preparation. Among 11 commercial proteases, Maxazyme NNP showed highest productivity (CS yield per enzyme cost) of CS. Optimal hydrolysis conditions determined by RSM were 1.63% and 2.87 hr for enzyme concentration and hydrolysis time ($r^2\;=\;0.9527$, p<0.0l), respectively and highest yield of hydrolysate under the conditions was 42.3%. The yield ($43.1{\pm}2.1%$) and CS content ($24.8{\pm}0.1%$) of hydrolysate at optimal condition verified statistical optimization of SC enzymatic hydrolysis was valid.

In this paper, we examine the different viewpoints of teachers and undergraduates on middle school informatics textbook. For this research, a survey is conducted on middle school informatics teachers and undergraduates who are preparing the state examination for informatics-computer teachers. Items of the survey were chosen to investigate the level of completion on the contents and structure of the textbook and to examine overall satisfaction with the textbook. Seven items concerning the level of completion are based on national textbook authorization criteria. A t-test was performed to analyze meaningful difference in perception of textbook between the teacher and student groups. The result shows there is meaningful difference on two items which are 'compliance with informatics curriculum' and 'content selection and organization'.

The access control means the process to record and manage access restrictions and permits for protecting information in records. This paper emphasizes the control of access and authorization based on the roles and the data using activities of users as task performers. Also, it requires to gain the necessary approval in advance for important tasks such as mass inquiry and change on important information to influence the very existence of the whole organization. And then, it suggests that it is necessary to control some session of information with non-activity for certain time. Generally, this paper is to explain security elements of access control through various cases.

USIM(UMTS Subscriber Identity Module) technology that accept 3GPP(3rd Generation Partnership Project) standards for information security supports security function in 3GPP. Supported security functions of USIM are confidentiality of user identity, mutual authentication and key agreement between end user and network, confidentiality of user data and data integrity. It is very important technology in wireless network. It makes secure environment that user and service provider can use securely mobile service in network. In this paper, design and implementation USIM security module that supports common network access method and authentication protocol in 3GPP and WLAN(Wireless LAN) and AAA (3A-Authentication Authorization Accounting) server system based RADIUS.
