  • In this paper, we study on an 'e-Atlas of Society & Culture(e-ASC)', to develop and implement educational courseware for marriage immigrant women, to adapt Korean society. The 'e-ASC' can help cultural adaptation, such as the understanding of Korean people's common values and behaviors and can likewise provide opportunities to contribute to Korean society, for marriage immigrant women living in Korea. E-cultural map is a useful tool for providing educational experiences and sharing a sociocultural homogeneity, using three dimensional space, for both immigrants and residents. The 'e-Atlas of Society & Culture', suggested in this paper, using the notion of an E-cultural map, has a strong point. That is to say, the immigrants have contextual limitations about Korea and Korean culture, caused by some particular events in their motherland. This atlas provides an opportunity to overcome this contextual limitations and to help understand and adapt to Korean society for these immigrants. This 'e-Atlas of Society & Culture' can be an efficient educational tool for immigrants and can help marriage immigrant women understand and adapt Korean social and cultural phenomena. They might have contextual limitations about these phenomena in their motherland.

  • Readability, an indicator measuring the easiness of reading letters, is an important element that determines the communicative effectiveness of self-guided signs. This study examined how the letter design elements of self-guided signs influence on readability to provide basic information for more effective sign designs. Data were collected from August to November of 2003 at a self-guided trail of Naejangsan National Park, Korea. A total of 375 subjects participated in the questionnaire survey, and 94.7% of them were used for data analysis. Among the total of 19 attributes, five attributes such as number of letters, number of type styles, ratio of picture area on the signs, space between letters, type size influenced on readability. These five attributes explained 50.0% of the variation in readability. The number of letters was the most influential attributes on readability, followed by the number of type styles, ratio of picture area on the signs, space between letters, and type size. The effectiveness of signs may be efficiently increased by managing these five major attributes with more concern.

  • The tactical mobile communication network, which comprises a part of the next-generation Tactical Information and Communication Network (TICN), provides means of communication and control for Tactical Multi-Functional Terminals (TMFT) belonging to a Mobile Subscriber Access Point (MSAP). The next-generation of MSAP is capable of constructing a backbone network via LCTR and HCTR directional antennas. At the same time, WMN modules are used to create and manage a wireless mesh backbone. When directional antennas are used in mobile environments, seamless services cannot be efficiently supported as the movement of the node prevents the angle of the antenna to constantly match. Therefore, data communication through the wireless mesh networks is required to provide direct communication between mobile MSAPs. Accordingly, mutual authentication and data encryption mechanisms are required to provide reliable data transmission in this environment. To provide efficient mutual authentication between MSAP devices, the process of verifying a certificate of the other MSAP device through its own authentication server is required. This paper proposes mutual authentication mechanisms where the MSAP requiring authentication and the MSAP that permits it initiates low-cost and efficient authentication in a distributed way. More specifically, we propose a method of applying EAP-ELS (Extensible Authentication Protocol-Transport Layer Security) in the next-generation TICN.

  • Carbon neutrality, the international community's practical challenge in response to climate change, is becoming a key industrial strategy for the future development of nations. Despite concerns that China, as an economic powerhouse in the G2, may face challenges leading global climate change efforts due to its high-carbon-emitting industrial structure, it is leveraging carbon neutrality to enhance its industrial competitiveness. The Chinese government has formulated national policies for achieving carbon neutrality and detailed sector-specific plans to implement them. In particular, it aims to leverage carbon neutrality industrial strategies as a lever for adjusting the domestic industrial structure and fostering new industries, at the same time responding to international climate norms and external pressures. However, the effectiveness of carbon-neutral industrial strategies is expected to vary based on regional conditions such as economic and industrial levels. This article analyzes the regional conditions for implementing carbon neutrality in China, as well as the contents and characteristics of major industrial policies. Due to differing levels of economic development and industrial structures, significant variations in carbon emissions, size, emission sources, and efficiency are inevitable across regions. These disparities introduce diverse initial conditions and endogenous factors in pursuing carbon-neutral goals, limiting the direction and implementation of carbon-neutral industrial strategies favoring certain regions. In particular, the extent of policy autonomy granted to local governments regarding carbon neutrality implementation will influence the regional dynamics of central-local environmental governance. Consequently, it is crucial to emphasize regional monitoring alongside comprehensive national research to accurately navigate the path towards carbon neutrality in China. In summary, the article underscores the importance of understanding regional variations in economic development, industrial structure, and policy autonomy for successful carbon neutrality implementation in China. It highlights the need for regional monitoring and comprehensive national research to determine a more precise direction for achieving carbon neutrality.

  • In logistics and distribution, Market Basket Analysis (MBA) is used as an important means to analyze the correlation between major sales products and to increase internal operational efficiency. In particular, the results of market basket analysis are used as important reference data for decision-making processes such as product purchase prediction, product recommendation, and product display structure in stores. With the recent development of e-commerce, the number of items handled by a single distribution and logistics company has rapidly increased, And the existing analytical methods such as Apriori and FP-Growth have slowed down due to the exponential increase in the amount of calculation and applied to actual business. There is a limit to examining important association rules to overcome this limitation, In this study, at the Main-Category level, which is the highest classification system of products, the utility item set mining technique that can consider the sales volume of products together was used to first select a group of products mainly sold together. Then, at the sub-category level, the types of products sold together were identified using FP-Growth. By using this sequential layer filtering technique, it may be possible to reduce the unnecessary calculations and to find practically usable rules for enhancing the effectiveness and profitability.
