This study analyzes how the perceived pressures and organizational readiness of fashion companies (that utilize the internet as a marketing or commercial transaction tool) influence the continuous internet adaptation intention. It ascertains the differences between the companies that have introduced the internet commercial transaction and companies that have not. The survey was conducted among the employees of fashion companies from January $15^{th}$ to February $20^{th}$ in 2009. A total of 314 respondents were submitted for analysis using diverse methods that include frequency analysis, factor analysis, reliability analysis, t-test, and multiple regression analysis. The results show that the perceived internal and external pressures, the support of the chief executive officer and capacity of the organization influence the continuous internet adaptation intention of fashion companies. There are differences in the perceived internal and external pressures, support of the chief executive officer, capacity of the organization, and continuous internet adaptation intention between companies that introduced a internet commercial transaction system and those that have not.

This study aims to enhance the accuracy of fine dust predictions by analyzing various factors within the local environment, in addition to atmospheric conditions. In the atmospheric environment, meteorological and air pollution data were utilized, and additional factors contributing to fine dust generation within the region, such as traffic volume and electricity transaction data, were sequentially incorporated for analysis. XGBoost, Random Forest, and ANN (Artificial Neural Network) were employed for the analysis. As variables were added, all algorithms demonstrated improved performance. Particularly noteworthy was the Artificial Neural Network, which, when using atmospheric conditions as a variable, resulted in an MAE of 6.25. Upon the addition of traffic volume, the MAE decreased to 5.49, and further inclusion of power transaction data led to a notable improvement, resulting in an MAE of 4.61. This research provides valuable insights for proactive measures against air pollution by predicting future fine dust levels.

2008년 금융위기 사태가 발생한 이후 금융 시스템의 중앙집권의 위험성을 인지하면서 시작된 것이 블록체인이다. 2008년 시작점으로부터 지금까지 블록체인은 비트코인이라는 블록체인 기술 기반 암호화폐란 엄청난 혁신을 시작으로 많은 관심과 기술의 발전이 이루어지고 있는 상황이다. 하지만 이 또한 시간이 지나면서 취약점이 발견되었고 피해 사례 또한 자주 일어나고 있다. 그러나 현재 21세기 4차 산업에 있어 핵심 기술이며 앞으로도 많은 발전과 이를 기반으로 한 기술들이 다수 출현할 것으로 예상된다. 따라서 본 논문은 암호화폐 거래에서의 취약점을 분석하고 새로운 거래 프로토콜을 제안한다. 제안하는 거래 프로토콜은 거래가 끝나는 시점에서 한 번 더 인증을 하게 되고 이러한 인증으로 거래가 성사되는 방식이다. 거래 취약점에 대한 내부적 보안이 아닌 거래 과정에서 사용자들 간의 보안요소를 추가하여 대응방안을 제안한다.

CDM(Clean Development Mechanism) project is said to be a mechanism, which profits both the investing country and the host country, while additionally contributing to the reduction of greenhouse gases of the earth as a whole. However in reality, most of the proposed projects do not end up in agreement because of the problems related to differences in recognition between the investing country and the host country of the CDM project. This outlines the background for this research which proposes a new design of institutional arrangements of CDM projects in the Northeast Asian region, mainly Japan, China and Korea. In addition, we investigate the feasibility of the proposed design. The research firstly focuses on the reduction in transaction costs that the participation of Korea will have on a Japan-China CDM project. This paper further emphasizes the potential gains that would materialize if a CDM project involved the whole Northeast Asian region, and not only one country. Our research suggests that an approximate reduction of 23% in transaction costs, and about 4% reduction in the total costs of a CDM project can be expected to follow the Korean participation. In addition to decreasing costs we find that a Korean involvement in a CDM project with Japan will lead to efficiency gains illustrated by a higher increase in the IRR(Internal rate of return) in a Japan-Korea project(11.45% to 12.21%) compared to an IRR incresement of 10.57% to 11.27% for a pure Japanese CDM project. Similar results of a rise in the IRR is found for the whole investment period of 20 years. We can hence conclude that Korean participation in a Japan-China CDM project would improve the implementation possibilities of CDM project in the Northeast Asia region.

The telecommunications of previous years have been utilized for internal usages, but those in current years have widely extended even to usages for Interorganizational Information System(IOIS) beyond its internal uses. Electronic Data Interchange(EDI), a subsidiary form of IOIS which permits interorganizational electronical exchanges of transaction documents through the telecommunications networks between and among computers, is expected to bring forth various innovative results with improved efficiency and productivity through the improvement and simplification of transaction processes, And it became needed and significant to review studies with practical values and necessity. This study is implemented on the basis of a judgement that Korea businesses can improve some of their structural problems of high costs by successfully adopting and implementing EDI system in their organizations. And it's also realized that more studies on the related subjects will benefit and be valuable for various applications. The major objectives of this research is to identify factors influencing in the implementation of EDI system by Korean business entities. Business which already implementation EDI system in their organizations were subjected to the survey. Also, this study intended to identify variables influencing in the implementation of EDI system and further provide directions needed in establishing or managing EDI system.

As the e-marketplace becomes the core of management activities, researches on motivation, transaction type, strategy, satisfaction, risk management, performance evaluation, etc. have been actively studied, but the factors influencing actual utilization have not been fully. Especially, the factors that affect the intention of the users are limited without consideration of internal environment, external environment, e-marketplace characteristics such as operating rules, characteristics of the company to be used. In order to derive the determinants of B2B e-marketplace use, this study was conducted to examine the relationship between internal environment, external environment, e-marketplace characteristics as independent variables, intention of use as dependent variable, participation qualification, The results were as follows. First, the previous study limited the determinants of intention to use to either internal or external, but this study presented an integrated model that considers both factors. Second, the characteristics of companies participating in e-marketplace were identified by using participation qualification and activity scope as control variables.

Secure digital payment is critical in the successful shaping of global digital business. Digital payments are increasingly being used as a substitute to traditional payments, contributing markedly to the efficiency of the economy. The focus of every digital business transaction is to minimize risks arising from transactions. It is essential to ensure the security of digital payment whether used in internal networks or over wireless Internet. This paper analyses secure digital payment methods from the viewpoint of systemic security and transaction security. According to comparative analysis of digital payment models, this paper proposes a comparative analysis framework to investigate and evaluate secure digital payment. In conclusion, the comparative analysis framework, comparison of digital payment models and mobile payment models proposes a useful academic and practical foundation to enhance the understanding of secure digital payment methods. It also provides academic background and practical guidelines for the development of secure digital payment systems.
