The traffic classification is a preliminary and essential step for stable network service provision and efficient network resource management. However, the payload signature-based method has significant drawbacks in high-speed network environment that the processing speed is much slower than other methods such as header-based and statistical methods. In addition, as signature numbers are increasing, traffic analysis speed also declines because of signature matching method that does not consider analytic efficiency of each signature and traffic occurrence feature. In this paper, we propose a signature list reordering method in order by analytic value of each signature. When we reordered the signature list by the proposed method, we achieved about 30% improvement in speed of the traffic analysis compared with random signature list.

This study empirically analyzed how human resource management(HRM) practices affect the performance of venture firms using The results of the study are as follows: First of all, several HRM practices were found to affect organizational performance significantly. Specifically, ${(1)}$ recruitment and selection practices were negatively related to turnover, which seemed to mean that effective staffing including development of good recruitment pools and rigorous selection process lower turnover, and ${(2)}$ training and development, compensation, and labor-management relations were positively related to subjective performance of the firms, which implied that as the venture firms provide more opportunities of training and development to employees, provide compensation on the basis of performance, and develop cooperative labor-management relations, the subjective performance of the venture firms Increases. Secondly, negative interaction effects were found to exist between competitive strategies and HRM practices on organizational performance. Specifically, ${(1)}$ the interaction between differentiation strategy and compensation were significantly related to turnover, ${(2)}$ HRM planning and training and development interacted with differentiation strategy to significantly affect subjective organizational performance, and ${(3)}$ HRM planning, selection, training and development, compensation and communication practices interacted with technology innovation strategy to affect subjective organizational performance. So far, there have not been many studies which deal with HRM practices of venture firms in Korea. Thus, it is hoped that this study stimulate more research efforts on theory development and empirical studies on HRM practices of venture firms. Also, it is hoped that government conduct more policy studies and provide more resources in HRM area of the venture firms. Specifically, it is suggested that government take proactive steps to improve industrial skilled staff and technical researcher systems in order to alleviate the problems of workforce shortages in venture firms. And it IS also suggested that regional human resource development programs be introduced with the participation of the firms, local governments, and universities.

Recently, urban parks are required to actively participate with residents in order to strengthen social functions and maintain sustainable management. This study analyzed the formation process of volunteer resident groups (Chamsamo) in the neighborhood parks in which local residents can participate in an ongoing basis based on the solidarity of a daily living space. The important factors in the activation of resident activity are derived from 5 aspects including resources, local area, resident group capacity, resident group role, and public support. The results of the study are as follows. 1) Life-friendly resources: It was important to find life-friendly resources such as 'Chamsaem' in the park. The combined resources of continuous human activities provided various benefits to the residents. This has led to stronger attachment and community activities to continue to utilize attractive resources in the park. 2) Sharing Common Daily Spaces and Expansion: As the Chamsamo activities were centered around the neighborhood, the network of activists in the local community expanded. This led to continued resident interest and favorable participation as well as to the regional expansion of Chamsamo activities. 3) Park management as part of everyday life: Park management became a part of everyday life, and pleasant park management was facilitated by utilizing the talents of the residents, who carried out diverse activities and constantly streamlined their hard labor. 4) Chamsamo's Leadership Linking Residents and the Public Sector through Leading Park Management Activities: Chamsamo served as a middle leader in linking the public sector and its users. 5) Role and Support of the Public Sector: In order to be able to sustain the activities of residents, the government's willingness to support the resident-led activities of the park in planning and operating the public sector was required. In the public management system of the park, support for residents' activities such as financing, education, and consulting was necessary.

The promotion of overseas projects by construction enterprises has appeared as a way to overcome the current business difficulties of the Korean construction industry, which largely caused by the slow growth of the domestic market and the intensified competition among construction companies. The government has also shown considerable interests in the strategic approach of promoting construction projects by private companies in natural resource-rich countries, which helps the internationalization of Korean companies and the acouisition of natural resources. In this regard, this research examines the status of the construction market in the Democratic Republic of the Congo(DRC) whose potential economic growth is considered as significant, while exploring the appropriate Investment strategies of Korean construction enterprise. Since little appears to be known about the construction market and economic conditions of the DRC, after a documented review of the development trajectory of the country, a field investigation was preformed in June 2008 for obtaining information on the subjects. This research finds that the road construction is the area to fulfill the several important criteria of implementing construction projects in developing regions, including the safety/reliability for gaining investment profits, the possibility of implementing construction projects on the gradual basis, the possibility of using the facilities after the project completion, and the linkage between payment and the construction stages. In regard to the current economic situation of the DRC and the policies of the DRC government, a package deal approach, which contains the exchange of the infrastructure construction by the Korean companies and the provision of natural resources by the DRC government, is the most feasible method for Korean companies to promote their businesses in the DRC's construction market.

Since the recent financial crisis in universities has caused the decrease of academic library budget, the resource sharing has been considered by utilizing inter-library loan (ILL) data for solving the financial deficit. This study aims to identify the collection profiles of western monographs' ILL data among 4-year academic libraries. In order to achieve the purpose of this study, this study analyzes ILL data from 2011 to 2017 using the bibliographic data and ILL transactions of the KERIS union catalog. The findings of the study show that the western monographs was significantly provided by large-scale academic libraries in 2011, however, the extent of major regions expanded, and the number of influential institutions rose in 2016. Second, in 2012, the influence in the ILL network increased in the quantity of western monographs holdings and the proportion of common collections. On the other hand, in 2016, it was also shown that the influence in terms of provision in the ILL network increased in the proportion of unique collections. Lastly, the ILL participating academic libraries were classified into six clusters by a hierarchical clustering analysis of holdings and ILL indexes.

The purpose of this study is to identify increasing needs for training students as managers in social service agencies and to suggest ways to develop the education of social welfare administration. Agency evaluations and performance management has increased demands for effectiveness and accountability of social service agencies, which also has increased the roles of managers in social service agencies. Using 'Korean Social Worker Survey' conducted by Korean Association of Social Workers, this study examines job characteristics of 2,479 social workers. The results show that administration/management activities take about 40% of social workers' daily activities. Community organization, human resource management, and planning/financial management are regarded as more important and difficult than other tasks. However, sufficient education for preparing students as social service managers is not provided in undergraduate and graduate level of college education. In addition, social workers make their life long careers as managers. Thus, the education of social welfare administration needs to refocus on the provision of knowledge and skills required for competent social service managers. This study suggests future directions for developing education of social welfare administration in undergraduate and graduate level of college education including field practice.

There has been constant attempts for integration of public welfare delivery system which lead to integrated case management, then this become more significant issue regarding 'community care' recently in Korea. However, most of them was limited to fractional organization rearrangement or more use of private resources rather than realising user-centred approach. Therefore, in this research, we would like to do a couple of case studies in Britain which has rich experience of reforms for integrated approaches between health and social services and Troubled Family programme resembles the integrated case management in Korea by visiting a London Borough and a local council respectively. In conclusion, we found three conditions are required to establish successful integrated delivery system: elimination of institutional barriers relating to workforce, organization, and finance; shared objectives and partnership among the professional groups and agencies; and information sharing system with technical support regarding individual cases.
