The GOOSE(Generic Object Oriented Substation Event) is used as a network protocol to communicate between IEDs(Intelligent Electronic Devices) in international standard IEC 61850 of substation automation system. Nevertheless, the GOOSE protocol is facing many similar threats used in TCP/IP protocol due to ethernet-based operation. In this paper, we develop a IDS(Intrusion Detection System) for secure GOOSE Protocol using open software-based IDS Snort. In this IDS, two security functions for keyword search and DoS attack detection are implemented through improvement of decoding and preprocessing component modules. And we also implement the GOOSE IDS and verify its accuracy using GOOSE packet generation and communication experiment.

Purpose: The purpose of this study was to identify social support networks for each life-cycle stage of adults. Method: A total of 1,047 subjects included 454 young adults, 262 middle-aged adults and 331 senior adults. Data were collected using Oh's Korean Version Norbeck's Social Support Questionnaire (NSSQ), and analyzed using descriptive statistics, t-test, and ANOVA. Result: For the young adults, parents were the top and second priority as important social support resources, the third was siblings, and then friends. For the middle-aged, spouse was the first priority as an important social support resource, while the second and the third were children. For the senior adults, children ranked from the top to the seventh priority. The mean number of social support resources was 13.23 for the young adult, 12.93 for the middle-aged and 5.30 for the senior adults. Social support networks of the young adults significantly differed according to gender and marital status. That of the middle-aged significantly differed according to family size. In addition, that of the senior adults was significantly different according to marital status, economic status, religion and family size. Conclusion: It is essential to consider social support networks for each life-cycle stage of adults when making a social support intervention program.

The value chain is analytically useful for the cultural industry that has the characteristics of both manufacture and service industry, as the focus of value chain analysis moves from manufacturing only to the other stages of activity involved in supplying goods and services to consumers. The aim of paper is to analyse the value chain of the cultural industry in Gyeongbuk, find out the strengths and weaknesses of it, and suggest the ways to enhance the innovation capabilities of cultural industry in Gyeongbuk. First, the firms in advertisement & marketing, and circulation & distribution have low percent in cultural industry and need the low level of human resource, but produce high value-added in value chain; so, we should facilitate the make-up of the firms in advertisement & marketing, and circulation & distribution. Second, we should strengthen inter-firm networks to facilitate the ex-change of the equipment, human resource, information and technology between them. Third, we should construct the system to development human resource with two levels and spread the open atmosphere of firms.

The purpose of this study is to determine what factors affect the marital life of multicultural families. In-depth interviews were conducted with 15 immigrated females and their husbands living in Yongsan-Gu, Seoul, Korea, by open-ended questionnaire. The interviews took place on September 11, 2008, and October 11, 2008. The major findings can be summarized as follows: Through the content analysis of the informants' responses, three major factors were found to influence the successful adjustment of the married female immigrants: personal factors, familial support, and social support systems. Among the personal factors, the self-esteem of the married couples is relatively high. However, the factor of the economic living conditions of the multicultural families indicates some difficulty. Finally, considering the level of self-development of the female immigrants' husbands, an older husband was viewed more negatively than a younger one. In terms of familial support, the most important factor affecting the adjustment of a foreign wife is the trust of her husband and her relationship with the husband's family. Accordingly, educational programs are necessary to promote multicultural understanding and the couples' relations. In social support systems, the female immigrants experienced neglect, as far as multicultural prejudice in society. Therefore, in order to revitalize the self-esteem of immigrants, we need to reach out to multicultural families. The center for support of multicultural families provides opportunities to find training, upgrade education for employment, and expand their social network. In addition, it is necessary for the national public relations industry to recognize improvements regarding the adjustment of multicultural families.

The companies have employed SNS for marketing, promotion, and customer relationship management. The SNS is a good tool to collect customers' opinions and to collaborate with internal and external employees, however, the function of SNS are limited in implementing a co-creation. Therefore, the purpose of this research is to suggest a SNS platform for co-creation that creates a corporate's values with customers. For this purpose, the limitations of SNS are defined and the new platform of the SNS is suggested. The proposed platform has 3 modules including integration of applications, cloud services, and integration to applications operated by companies. With a scenario method the suggested platform was validated. This is one of pioneer studies in co-creation.

This paper seeks to analyze how the welfare state has developed both in the Kim Young Sam government and in the Kim Dae Jung government. Among other things, the two governments share some similarities: compared to the previous authoritarian governments, both of them enjoyed a high level of democratic legitimacy; the two were under pressure to win the elections to acquire and remain in power; and finally, the two tried to strengthen welfare system. But there exist more critical differences. The Kim Dae Jung government was a minority government, while the Kim Young Sam government was a majority one. Compared to the latter one, the former came to power in an extremely bad economic condition. Fortunately, however, the Kim Dae Jung government was able to enjoy a relatively high level of state autonomy resulting from an exceptional situation of foreign currency crisis. In addition, it was more reformist in policy orientation and had a more open cooperative network with civil society. All these differences added up to produce remarkable differences with regard to the improvement in welfare development. Especially, it is noted that the Kim Dae Jung government was very successful in several respects: provision of national minimum, integration of national medical insurance, development of productive welfare system, and final1y increase in welfare spending. Recently, criticisms from the opposition party, the press, and middle and upper class people mount against the Kim Dae Jung government which has made significant mistakes in instituting the separation of medical and pharmaceutical businesses. However, the important improvements in welfare institutions and programs by the Kim Dae Jung government need to be maintained to deal with all the negative effects of a naked market economy. They must also be sustained to keep alive democracy that Korean people have fought for nearly half a century.

In this paper, we propose a broadband vehicle antenna that can operate at the WiBro band(2.3~2.4 GHz) for a wireless internet service. The feeding of the proposed antenna consists of two T-matching networks on both side of the polyarcylate substrate, and the two T-matching networks are connected through via holes. The designed antenna was built and installed on a rear window of a commercial sedan, and the antenna performances, such as the reflection coefficients and the radiation gain are measured in the open-sight area. The received signal strength of the designed antenna was also tested in a strong field area as well as in a weak field area. The measurement results show the matching bandwidth($S_{11}$ <10 dB) of about 300 MHz in the WiBro band and the average gain of about -5.13 dBi along the azimuth direction.

As the developments of smart devices and social network services, the amount of data has been exploding. The world is facing Big data era. For these reasons, the Big data processing technology which is a new technology that can handle such data has attracted much attention. One of the most representative technologies is Hadoop. Hadoop Distributed File System(HDFS) designed to run on commercial Linux server is an open source framework and can store many terabytes of data. The initial version of Hadoop did not consider security because it only focused on efficient Big data processing. As the number of users rapidly increases, a lot of sensitive data including personal information were stored on HDFS. So Hadoop announced a new version that introduces Kerberos and token system in 2009. However, this system is vulnerable to the replay attack, impersonation attack and other attacks. In this paper, we analyze these vulnerabilities of HDFS security and propose a new protocol which complements these vulnerabilities and maintains the performance of Hadoop.
