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.

Although awareness of the need to respond to climate change is expanding, various controversies are being raised about the EU's Carbon Border Adjustment Mechanism (CBAM). The EU has announced that they will implement CBAM as responding to climate change and preventing carbon leakage. However, the questions are raised as to whether it is actually effective in preventing carbon leakage. Above all, CBAM has its own contradictions, thus it could not be easy to implement. This is because the possibility of violation of the WTO principles is high and there are many issues in implementation. Emission Trading System (ETS) based on CBAM differs by country, and international linkage is not easy in that ETS is not a widely used system worldwide. The EU's CBAM is highly likely to be used as a trade restrictive tool, and is inevitably subject to trade disputes in that it imposes additional tariffs. The unilateral implementation of CBAM should be restrained unless support from the international community and consideration for developing countries are not taken into account.

In this paper, an algorithm of CBAM(Combination Bidirectional Associative Memory) model proposes, analyzes and tests CBAM model `s performancess by simulating with recalls and recognitions of patterns. In learning-procedure each correlation matrix of training patterns is obtained. As each correlation matrix's some elements correspond to juxtaposition, all correlation matrices are merged into one matrix (Combination Correlation Matrix, CCM). In recall-procedure, CCM is decomposed into a number of correlation matrices by spiliting its elements into the number of elements corresponding to all training patterns. Recalled patterns are obtained by multiplying input pattern with all correlation matrices and selecting a pattern which has the smallest value of energy function. By using a CBAM model, we have some advantages. First, all pattern having less than 20% of noise can be recalled. Second, memory capacity of CBAM model, can be further increased to include English alphabets or patterns. Third, learning time of CBAM model can be reduced greatly because of operation to make CCM.

인공지능 시대에 들어서면서 개인 맞춤형 환경을 제공하기 위하여 사람의 감정을 인식하고 교감하는 기술이 많이 발전되고 있다. 사람의 감정을 인식하는 방법으로는 얼굴, 음성, 신체 동작, 생체 신호 등이 있지만 이 중 가장 직관적이면서도 쉽게 접할 수 있는 것은 표정이다. 따라서, 본 논문에서는 정확도 높은 얼굴 감정 식별을 위해서 Convolution Block Attention Module(CBAM)의 각 Gate와 Residual Block, Skip Connection을 이용한 Identity- CBAM Module을 제안한다. CBAM의 각 Gate와 Residual Block을 이용하여 각각의 표정에 대한 핵심 특징 정보들을 강조하여 Context 한 모델로 변화시켜주는 효과를 가지게 하였으며 Skip-Connection을 이용하여 기울기 소실 및 폭발에 강인하게 해주는 모듈을 제안한다. AI-HUB의 한국인 감정 인식을 위한 복합 영상 데이터 세트를 이용하여 총 6개의 클래스로 구분하였으며, F1-Score, Accuracy 기준으로 Identity-CBAM 모듈을 적용하였을 때 Vanilla ResNet50, ResNet101 대비 F1-Score 0.4~2.7%, Accuracy 0.18~2.03%의 성능 향상을 달성하였다. 또한, Guided Backpropagation과 Guided GradCam을 통해 시각화하였을 때 중요 특징점들을 더 세밀하게 표현하는 것을 확인하였다. 결과적으로 이미지 내 표정 분류 Task에서 Vanilla ResNet50, ResNet101을 사용하는 것보다 Identity-CBAM Module을 함께 사용하는 것이 더 적합함을 입증하였다.

As new technologies change a society, librarians need to understand and adapt to technology innovations. However, most innovations that librarians are supposed to adopt are government-driven or top-down changes; and there have been very few studies conducted to identify any patterns or consistencies in librarians' perceptions of innovation. This paper, therefore, has two research purposes. First, it introduces the Concern Based Adoption Model (CBAM) as one method to gain a deeper understanding of how librarians see such changes. Second, this study identifies school librarians' concerns regarding digital textbooks in South Korea applying the CBAM theory. The test signifies that school librarians present a typical non-user profile, and the pattern anticipates a potential resistance to digital textbooks. Also, it discovers the less experienced and innovator librarians had higher concerns across every stage. The findings underscore a need of various interventions. The CBAM theory suggests, in terms of intense Stage 0 and 1, it is required for school librarians to have events to gain information about digital textbook implementation. Regarding targeted interventions, since the biggest gaps occurs in Stage 4, Consequence and Stage 5, Collaboration, according to school librarians' experience and adoption style, new school librarians need stronger engagement with the community, which including associations, mentors or peer support, and collaborating with public libraries; innovator school librarians require opportunities to test and present their use of digital textbooks (Hall and Hord 1987).

The purpose of this study was to reveal controversial issues on Stages of Concern(SoC), which is one of the dimensions of Concerns Based Adoption Model(CBAM). To achieve the purpose, documental analysis was employed. The theoretical framework to analyze literature consisted of three categories including stages, measurements, and applications. Based on the framework, controversial issues on SoC were discussed regarding arguments of CBAM developers and critics. The researchers of this study suggested their own opinions on the issues after thorough examination of CBAM developer's arguments and oppositions against them. Finally, suggestions for further studies on issues of SoC and studies measuring SoC were made.

In this study, LCA based on EU PAS 2050 and Product Category Rules (PCR) was conducted for steel products with the highest proportion of Korea's exports to the EU among the carbon border adjustment items that were passed by the EU Parliament in June and applied to imports from 2025. Carbon emissions were calculated by (ISO 14040) analysis. As a result of the analysis, the total emission is 394,000 tons, and when converted to the EU ETS weekly price, it is 39,000.000 euros, which is about 5% of the export amount of 734 million dollars. This is the same effect as a 5% tariff increase. This study applies international standards in calculating the carbon footprint and provides information that is closest to the expected amount to be imposed in the future EU CBAM, providing the effect of enabling exporters to establish trade strategies and international competitiveness measures in advance.
