The CBAM (Cost Benefit Analysis Method) provides a method for deciding the best architectural strategy by considering cost, schedule, and risks as well as the benefits of the architectural strategy. But many parts of the CBAM do not Present quantitative evidence explicitly on whether it is the best architectural strategy among others because it depends on the stakeholders' consensus, vote, and/or intuition. In this study, we apply the AHP (Analytic Hierarchy Process) to CBAM to provide explicit quantitative evidence and to reduce the possibility of subjective decision-making errors that may occur in the CBAM.

This study aims to identify the representation of migrants in the English-language media during the Brexit campaign period. For the purpose of this study, the methodological tool of corpus-assisted discourse studies(CADS) was employed and a collection was compiled of articles mentioning Brexit in British, American, Canadian, and Australian media from April 15 to June 22, 2016 in order to compare their portrayals of migrants. To examine how IMMIGRANT, MIGRANT, and REFUGEE are represented in the media, their collocates were analyzed by MI score and categorized by social actor categorization(Van Leeuwan, 1996). The results show that IMMIGRANT is related to collocates that refer to legal status and provenance, MIGRANT associated with economic terms, and REFUGEE relates to terms expressing quantities. The results also reveal that migrants are frequently depicted by functionalization, classification, and appraisement categorization and are more negatively portrayed in British and American media. This paper claims that corpus-assisted linguistic analysis of words enables one to identify salient linguistic patterns or lexical choices in the discourses about a particular phenomenon or group of people.

This paper introduces two concepts, specialization and representation, to evaluate activities of standing committees in Korean Assembly. Previous studies have criticized the committees based on frequent change of committee membership. After analyzing the empirical data of Finance and Economy Committee, it turns out that different from the previous arguments, the committee reaches the high level of activities in the perspective of specialization and representation. Changing of committee membership, after considering direction of the change and period of leaving the committee, is less happened than they are supposed. If voting by proxy or absentee voting were allowed, the frequency of the changing membership would be decreased. Study on Finance and Economy committee reveals that the extent of participation of the committee members is similar to the that of the floor meeting and that the number of participants and hours for each meeting display the characteristics of deliberative democracy of committee. Unanimous decisions outnumber majority ones. Therefore, this paper insists that standing committees in Korean Assembly works much better than what they have been criticized

Local governments within the boundaries of a state need increasing flexibility to satisfy diverse economic, social, and environmental goals in their particular geographical setting. However, many candidates in the local election in South Korea tend to see local politics as an extension of national-level politics. In particular, this paper mainly deals with how the voters' evaluation of a president's performance has influenced subnational elections in South Korea. Our analysis suggests that the fate of candidates in subnational elections is shaped by the performance of the incumbent president in both economic development and foreign affairs.

In this paper, we proposed the method computing the optimal solution of Optical Flow(OF) representing the moving information of moving object and improving the operating speed. In order to do that, we computed the optimal solution of OF using the Combinatorial Hough Transform(CHT) and Voting accumulation and simply searched the moving object compared to conventional method.

MMT (MPEG Media Transport) 기술은 지난 4년여 기간 동안 ISO MPEG의 표준화 과정을 거치면서 현재 FDIS (Final Draft for International Standard) 수준까지 도달하였고, 2014년 3월 스페인 발렌시아에서 개최될 제 108차 MPEG 회의에서 국가 투표 (national ballot)를 거쳐 IS (International Standard)로 승인될 예정이다. 본 고에서는 MMT 기술의 표준화 현황과 세부 기술 사항에 대해 분석한다. 또한, 하이브리드 미디어 전송을 지원하기 위한 MMT 표준기술의 기술적 사양에 대해 설명한다.

전자현금(Electronic Cash)이나 전자투표(Electornic Vote)에의 응용을 목적으로 Chaum에 의해 처음으로 RSA 기반의 은닉서명(Blind Signature) 개념을 제안하였다[1]. 휴대폰, 스마트카드와 같은 작은 용량의 메모리와 연산 능력을 가진 장치에서는 연산량이 작은 은닉서명 프로토콜을 필요로 한다. 본 논문에서는 사전계산과 효율적인 이차잉여 선택 방법을 이용하여 Rabin 기반 전자서명 방법에 은닉서명 개념을 도입하여 효율적인 Rabin 기반의 은닉 서명 프로토콜을 제안한다.

Existing research on international standardization has largely taken a qualitative approach focusing on comparative studies of national institutions and policies on standards or international rivalries from the perspectives of international relations or innovation studies. While there exists a handful of quantitative studies, they are mostly confined to simple numeric counts of essential patents, new work item proposals, or secretaries staffing international standards development organizations (SDOs). This study aims to contribute to our understanding of the dynamics of international standardization by the analysis of the data coding systematically national activities in the standardization process of the International Organization for Standardization (ISO), by far the largest international SDO. Our analysis of the four critical types of standardization documents generated in the Working Group 7 of the ISO/IEC Joint Technical Committee 1 reveals interesting dynamics among key players of global ICT standards regime. First, while the US takes a dominant share of the personnel as well as new work item proposals for standardization, its quality of activities rather falls behind as it mostly focuses on keeping in check other countries' standardization activities. Second, European countries tend to spread their effort evenly across different types of standardization activities. Finally, despite such differences between the US and European countries, both rely heavily on multinational companies to gain an advantage in the voting stage of standardization process.
