This study aims to determine if the current COVID-19 event can be admitted as an excuse for non-performance in international trade transactions. In order to do so, this study selected case study method in the analysis. Firstly, the definitions of Force Majeure addressed in CISG, UCC, Chinese Law, and Korean Law were organized. Secondly, this study reviewed the avian influenza event in 2006 and the natural disaster event occurred in Guangdong, China, in 2017. In the study, three critical evaluation factors are suggested in order to be admitted as a Force Majeure event in international transactions as following: 1) possibility of foresight of the event, 2) possibility to overcome and avoid the event, and 3) the enterprise's countermeasures of the event. As an implication, this study organized the definitions of Force Majeure that were indicated in various kinds of Laws and suggested the basic framework to analyze the possibility of admittance as a Force Majeure event.

Ontologies are knowledge containers in which information about a specified domain can be shared and reused. An event happens within a specific time and place and in which some actors engage and show specific action features. The fact is that several ontology models are based on events called Event-Based Models, where the event is an individual entity or concept connected with other entities to describe the underlying ontology because the event can be composed of spatiotemporal extents. However, current event-based ontologies are inadequate to bridge the gap between spatiotemporal extents and participants to describe a specific domain event. This paper reviews, describes, and compares the existing event-based ontologies. The paper compares and contrasts various ways of representing the events and how they have been modelled, constructed, and integrated with the ontologies. The primary criterion for comparison is based on the events' ability to represent spatial and temporal extent and the participants in the event.

Numerous types of sporting events have been hosted in Korea during the last decades. Sport events produce various types of data, and there is a clear necessity of storing and utilizing this information. From this background, the purpose of this study is to draw complex sports categories from international sport events life cycles in order to categorize standards of knowledges management system. This study utilized qualitative methods: expert groups discussion for overall life cycle steps and in-depth interviews for detail life cycle steps. The results show that there are several life cycle steps: bidding, preparation, operation, evaluation, post management steps. To be more specific, for the bidding step, there are check, plan, implementing detail phase; and the preparation step is based on event preparation Basis Build, event preparation implementation, test and supplementation phases. For the operation step, event operation system switch, event operation during the period, finish operation phases are deducted. Evaluation and post management step do not have detail phases. Efforts to store and utilize knowledge can be one of the starting points to make the operation of sport events efficiently.

The attack technique by the malware distribution form is a dangerous, difficult to detect and prevent attack method. Current malware detection studies and proposals are often based on two main methods: using sign sets and analyzing abnormal behaviors using machine learning or deep learning techniques. This paper will propose a method to detect malware on Endpoints based on Event IDs using deep learning. Event IDs are behaviors of malware tracked and collected on Endpoints' operating system kernel. The malware detection proposal based on Event IDs is a new research approach that has not been studied and proposed much. To achieve this purpose, this paper proposes to combine different data mining methods and deep learning algorithms. The data mining process is presented in detail in section 2 of the paper.

International sports events is one of the core products in the sports industry. The increasing number of nations are bidding to host the international sports event such as Olympics Game because of expecting to development of a city or nation. Hosting a international sports events are inter-connected and affected by system of socials, politics, cultures and economics. As the scale of the international sports events became larger, sports events process importance is growing. The purpose of this study was build a model of the sports event process in the attract steps. By analyzing event process in the attract steps, the core processes(1. Search, 2. Applications, 3. Practice, 4. Follow-up management) was set and stakeholders and function were analyzed. The modeling was used as IDEF method.

House load operation (HLO) occurs when the generator supplies power to the house load without triggering reactor trips during grid disturbances. In Korea, the HLO capability of optimized power reactor 1000 (OPR1000) plants has prevented several reactor trips. Operational experiences demonstrate the difference in the reactor trip incidence due to grid disturbances between OPR1000 plants and Westinghouse plants in Korea, attributable to the availability of the HLO capability. However, probabilistic safety assessments (PSAs) for OPR1000 plants have not considered their specific design features in the initiating event analyses. In an at-power PSA, the HLO capability can affect the initiating event frequencies of general transients (GTRN) and loss of offsite power (LOOP), resulting from transients within the grid system. The initiating event frequencies of GTRN and LOOP for an OPR1000 plant are reduced by 17.7% and 78.7%, respectively, compared to the Korean industry-average initiating event frequencies, and its core damage frequency from internal events is reduced by 15.2%. The explicit consideration of the HLO capability in initiating event analyses makes significant changes in the risk contributions of the initiating events. Consequently, for more realistic at-power PSAs in Korea, we recommend incorporating plant-specific HLO-related design features when estimating initiating event frequencies.

The future is complex and unpredictable. In particular, it is unlikely to occur, but once it occurs, no one knows how it will affect our society if X-event, which has a tremendous impact, is created. This study was conducted only in the climate field to offset the ripple effect of this X-event, and was conducted through in-depth interviews with experts from the Korea Army Research Center for Future & Innovation and the Army College. As a result, it was possible to explore what factors would trigger X-event from their discourse and what X-event would be newly created by spreading them to other fields. Starting with this study, if we accumulate the discourse of experts in various fields such as population, science and technology, as well as climate, and other fields other than the Army, we can predict X-event and offset the threats that may arise.

The objective of this study is to explore differential effects of the sustainability perceived by domestic and international participants in the MICE (Meetings, Incentive Travel, Convention, and Exhibition) held in the Republic of Korea and to examine the relationship between customer loyalty and perception of the sustainable MICE. In this study, 30 sustainability variables for the MICE were extracted and tested by the factor analysis, representing four underlying dimensions: economic sustainability, social sustainability, environmental sustainability and event sustainability. The results revealed that significant differences in these four dimensions of the sustainable MICE were perceived by domestic and international participants. The largest difference were perceived by domestic and international participants with respect to the environmental sustainability factor. The mean scores indicated that international participants tended to give higher evaluations than domestic participants. Second, there were statistically significant relationships among economic, environmental, and event sustainability factors and customer loyalty from the perspective of international participants. For domestic participants, only event sustainability had a vital relationship with customer loyalty. The study implied how policy makers and the MICE managers should adopt four dimensions of sustainability to establish a harmonious and sustainable MICE practices.

As a sign of international quality system, ISO9000 certification has been adopted by more and more enterprises. In recent five years, there have been 560,000 certified companies in Europe and America, and there have been more than 390,000 ones in China. It has being attracted many quality scholars' attentions whether ISO9000 certification can bring more benefits to certified companies or not. This paper investigates the ISO9000 certification effect on market performance by the samples from Chinese list companies in shanghai stock exchange. Considering ISO9000 certification as an event, a certification effect model will be set up by means of the event study method, which takes abnormal return rate as a basic indicator to measure the ISO9000 certification effect on Chinese market performance in different event times. Investigation results show that the Chinese certified companies have some positive effects on market performance in the short term. From a long standpoint, the relation between certification and performance has a positive trend.
