The CBD (Component Based Development) is a requisite technique for the Time-To-Market, and a highly reusable component should be provided to develop a variety of domain applications with the use of components. To increase the reusability of components, they should be developed by analyzing requirements of many different kinds of domains. However, to analyze requirements of a variety of domains related to the components to be developed and to include them inside the components will give burden to developers. Also, providing only general components that have common facilities for the several domains is not easy to accomplish the time-to-market since there are other domains that the developers have to develop. As such, developing common component through the analysis of several domains at the time of the CD (Component Development) does not always guarantee high reusability of the component, but gives burden to developers to develop another development since such components have common functions. Considering this, this paper proposes the component customization technique to reuse common components as well as special components. The reusability of the component can be increased by providing changeability of the attribute, behavior and message flow of the component. This customization technique can change the message flow to integrate developed components or to provide new functions within the component. Also, provides a technique to replace the class existing within the component with other class or to exchange the integrated component with the component having a different function so that requirements from a variety of domains may be satisfied. As such, this technique can accept the requirements of several domains. As such, this customization technique is not only the component with a common function, but it also secures reusability components in the special domain.

According to TIMSS, secondary math teachers in Korea has lower confidence compare to other countries, despite the fact that teachers' confidence of teaching is an important variable. This not only influences the student's improvement but, also the quality improvement of teachers' career. Therefore, this study explores the effect of secondary math teachers' confidence according to the context variables such as teaching years, teaching preparation, collaboration with other teachers, and teaching limitation. Additionally, these context variables' $R^2$ toward the change of teaching confidence is also included. Results indicate that teaching preparation, collaboration with other teachers, and teaching limitation contribute in the confidence of teaching. $R^2$ of the change of teaching confidence shows large contribution to teaching preparation which does not accomplish with other variables.

In order to decide the national technical standards policy for national policy/market economy activities, the people in charge commonly make policy decisions based on the current technology level/concentration/utilization by means of major common technology field analysis using patent data. One possible source of such patent data is the domestic mobile carriers through the Korea Intellectual Property Rights Information System (KIPRIS) of the Korean Intellectual Property Office (KIPO). Using this system, we collected 20,294 patents and 152 International Patent Classification (IPC) types and confirmed KTs (9,738 cases / 47.98%), which perform relatively high technology retention activities compared to other mobile carriers through the KIPRIS of KIPO. Based on these data, we performed three analyses (SNA, PCA, ARIMA) and extracted 30 IPC types from the SNA and 4 IPC types from the PCA. Based on the above analysis results, we confirmed that 4 IPC (H04W, H04B, G06Q, H04L) types are the major common technology field of the domestic mobile carriers. Finally, the number of 4 IPC (H04W, H04B, G06Q, H04L) forecast averages of the ARIMA forecast result is lower than the number of existing time series patent data averages.

The purpose of this study is to analyze the perception of integrated school education and education for sustainable development of secondary school science teachers, judging that the existence of a common science teacher qualification certificate is related to the expertise of the common science map. To that end, the survey was conducted for three months from June to August 2018 for secondary school science teachers, and multiple choice questions were analyzed as statistical processing and descriptive questions as topical modeling. According to the analysis, teachers with a common science teacher qualification certificate had a high awareness of integrated school education, and the response average was high in all areas of value, direction and success condition of integrated school education. In addition, the average response of teachers with a common science teacher qualification certificate was also found to be higher than those with a common science teacher qualification. There were no major differences in perception between the two groups on the strength of science education and ESD integration, but the difference was that teachers with a common science teaching certificate focused on science in all topics and recognized science as a medium for each topic compared to teachers who did not.

음성에 대한 청각적 판단으로는 차이점과 공통점을 느낄 수 있으나, 개별적인 음향 분석에서는 차이점이나 공통점을 밝혀 내지 못한 경우가 많았다 따라서 음성에 대한 청각적 판단처럼 음향 분석 변수를 종합적으로 분석할 수 있는 MDVP와 Phonetogram을 이용하여 음성질환별로 나타나는 소견을 관찰하여 청각적 판단과 종합적인 음향학적 분석간에 연관성이 있는지 알아보고자 하였다. 음성변화를 주소로 본원에 내원하였던 환자 중 화상회선경술 검사상 양성성대질환이 관찰되었던 102명을 대상으로 하였고, 성대질환이 없었던 정상군과 비교하였다. 각 대상들은 화상회선경술 검사에서 질환의 종류를 확인하였고, 질환별 청각적 분석을 GRBAS로 확인하였다. 또한 MDVP를 시행하여 질환별로 변수들의 특징적인 변화를 종합적으로 도식화하여 확인하였고, Phonetogram을 시행하여 질환별로 감소된 부분이 있는지 확인하였다.

Urbanization and income distribution issues are global interest, and the results of studies on the impact of urbanization on income inequality are different for each country and period. This study analyzes the impact of urbanization on income inequality using regional data from 2000-2021. In particular, serial correlation, spatial dependence, and common factor effects of the Gini coefficient are confirmed and analyzed through a dynamic spatial panel regression model. As a result, urbanization has a positive effect on reducing income inequality. Therefore, it is necessary to continuously promote regional urbanization to improve the income distribution problem. Areas with already high urbanization rates should reduce income inequality by narrowing the wage gap by expanding training opportunities for low-skilled workers, and need to come up with measures to prevent counter-urbanization.

Security Policy Model is a structured representation using informal, semiformal or formal method of security policy to be enforced by TOE. It provides TOE to get an assurance to mitigate security flaws resulted from inconsistency between security functional requirements and functional specifications. Therefore, Security Policy Model has been required under an hish evaluation assurance level on an evaluation criteria such as ISO/IEC 15408(Common Criteria, CC). In this paper, we present an evaluation method for security policy model based on assurance requirements for security policy model in Common Criteria through an analysis of concepts, related researches and assurance requirements for security policy model.

This study was performed to derive a modern service management model reflecting the philosophy of the new business administration. Service management as the modern business administration should be faithful to the spirit of modernity. In addition, service management must be faithful to the essence of service in service economy era. And since modern management is to manage organizations those are the central organizations of human society, it must be managed according to the common principles of the world. Management that satisfies these three management philosophy conditions is defined as modern service management. In this study, we analyzed that the existing service management framework does not meet these standards of modern management and derived an improved modern service management model. The modern service management model must be a management model that reflects the essence of intangible goods called service, it must be a management framework that reflects the modern spirit, and it must be a management model that reflects the common principles of the world required by the central organization of the modern economic society. Therefore, this study analyzed the modern spirit in addition to the service essence and the common principle of the world analyzed in the previous study, and presented a modern service management model with these three requirements. Also, examples of modern service management were presented. This study is a conceptual model, and analytical research is needed to demonstrate that this management model can consistently produce excellent management performance by strengthening empirical studies in the future.

Recently, most of global enterprises have geographically distributed organization, thus have distributed information systems which have distributed database systems. So, it is difficult for these systems to provide common views for the application programs of end users. One of solutions to solve these difficulties is an MDBS(Multidatabase System) A method to effectively implement MDBS is a schema integration. This paper proposes a methodology for a schema integration through extraction of common similar subschemas Our methodology is consisted of 5 phases : affinity analysis, extraction of similar subschemas, decision of imtegration order, resolution of semantic conflict, and schema integration. To verify the usability of our methodology, a case study is implemented with an object of MDBS. At a result, our approach can effectively be applied to the extraction of common similar subschemas and schema integration.
