  • Recently, software education has been emphasized as a key element of the fourth industrial revolution. Many universities are strengthening the software education for all students according to the needs of the times. The use of online content is an effective way to introduce SW education for all students. However, the provision of uniform online contents has limitations in that it does not consider individual characteristics(major, sw interest, comprehension, interests, etc.) of students. In this study, we propose a recommendation method that utilizes the directional similarity between contents in the boolean view history data environment. We propose a new item-based recommendation formula that uses the confidence value of association rule analysis as the similarity level and apply it to the data of domestic paid contents site. Experimental results show that the recommendation accuracy is improved than when using the traditional collaborative recommendation using cosine or jaccard for similarity measurements.

  • Recent incidents of lethal violence in the Rakhine State of Myanmar between the majority Buddhist Rakhine and the Muslim Rohingya have been the source of much concern for the international community. Unlike the past, the killings and incendiary attacks by both communities have intensified to a critical level, proving to be a great liability for the forward-thinking Myanmar government, whose recent transition to civilian rule after a long military one has made it eager to move on. The roots of the conflict trace back to the military regime, who branded the Rohingyas living in Rakhine state as illegal immigrants and refused to confer upon them official recognition as Myanmar citizens. The discord then moved to an ethnic conflict, pitting the Rohingya not merely against the Myanmar government but rather the majority Buddhist Rakhine. The conflict, as it has developed into the present, is an immensely complicated one that simultaneously encompasses ethnic and religious issues, all intertwined together. This study aims to see how the two ethnic groups have come to resort to such violence, despite having lived in each other's presence for many centuries, and why the violence persists. It will attempt to reconcile the fact that Rakhine had historically been a place of convergence for two groups, the Buddhist Rakhine and the Rakhine Muslim(the Rohingya). Based on the argument, this study also seeks to uncover, identify, and understand the Rohingya identity with the extreme arguments exhibited by both sides, and from there, locate the underlying causes of the greater religio-ethnic conflict in Rakhine that has so ravaged the place as of recent.

  • As Internet lastly grows, network attack techniques are transformed and new attack types are appearing. The existing network-based intrusion detection systems detect well known attack, but the false-positive or false-negative against unknown attack is appearing high. In addition, The existing network-based intrusion detection systems is difficult to real time detection against a large network pack data in the network and to response and recognition against new attack type. Therefore, it requires method to heighten the detection rate about a various large dataset and to reduce the false-positive. In this paper, we propose method to reduce the false-positive using multi-level detection algorithm, that is combine the multidimensional Apriori algorithm and the modified Negative Selection algorithm. And we apply this algorithm in intrusion detection and, to be sure, it has a good performance.

  • Carbon neutral policy in Korea pays limited attention to the concept of sustainable economic growth. This limitation can be compared with other countries' carbon neutral policies such as US, UK and China where the climate change policies are closely connected to economic policies to boost further economic growth. This paper adopts a Ramsey growth model to account for the impact of carbon neutral policy on long-term economic growth and the accumulation capital. The model incorporates the Hartwick rule to allow sustainability of economic growth by transforming resource input into other input factor for growth. The analysis provides a possibility of low accumulation of capital as a result of carbon neutral policy in the absence of effective transformation of fossil-fuel factor into growth-related productive capital. Such low capital stock can be more aggravated when there exists a rent-seeking behavior of various interest groups with voracity to exploit social capital.

  • Purpose - Recent empirical studies have shown that FDI is expected to be strongly associated with democratic governance, political stability, and sound macroeconomic conditions of the host country. We attempt to take it a step further to see if governments implement a major change in institutional characteristics, will the institutional reform toward better governance have a substantive effect in enhancing FDI inflows. This paper thus aims to analyze the importance of good governance as an important factor in the attractiveness of FDI inflows in ASEAN+3 (Korea, China, Japan) countries. Design/methodology - To determine the effects of good governance on FDI inflows across ASEAN+3 countries recorded between 1996-2018, the Worldwide Governance Indicators (WGI) are used to investigate the impact of good governance on FDI inflows. The model has been estimated by using fixed effects to show the robustness of the results. Findings - Our main findings can be summarized as follows: Political Stability, Rule of Law, and Voice and Accountability have a statistically significant impact on the inflow of FDI in the ASEAN+3 Countries, especially for Korean economy. Moreover, GDP growth continue to exert their positive influence. However, Regulatory Quality, Government Effectiveness and Control of Corruption, though equally important, are insignificant to attract FDI inflows. The key finding is that good governance has a significant impact on inward FDI in the ASEAN+3 countries. Originality/value - Existing studies focus on the impact of political factors on FDI across countries. This paper instead attempts to investigate which type of good governance is the most important in promoting FDI inflows across ASEAN+3 countries, which is essential for multinationals to consider when choosing a foreign site as a possible FDI destination.

  • Purpose - This paper examines the legal standards for the interpretation of contract terms in the UNIDROIT Principles of International Commercial Contracts (PICC) and the cases thereunder in order to provide academic implication to promoting an appropriate understanding of this topic in practical business. Design/methodology - This article uses the literature research and case study under the PICC. Findings - the contract terms shall be interpreted according to the common intention of the parties. If such an intention cannot be established, the contract shall be interpreted according to the meaning that reasonable persons of the same kind as the parties would give to it in the same circumstances. The statements and other conduct of a party shall be interpreted according to that party's intention if the other party knew or could not have been unaware of that intention. If not, the reasonable person standard will apply. In applying above articles, all relevant circumstances including the conduct of the parties, practices and usages shall be considered. Terms and expressions shall be interpreted in the light of the whole contract or statement in which they appear and contract terms shall be interpreted so as to give effect to all the terms rather than to deprive some of them of effect. Where contract terms supplied by one party are unclear, contra proferentem rule applies. Where there is discrepancy between several equally authoritative versions of a contract, a preference is given to the interpretation according to the version originally drawn up. Where the parties to a contract have not agreed regarding an important term for their rights and duties, a term which is appropriate in the circumstances shall be supplied. Originality/value - This article examines various cases regarding the topic that were determined under the PICC. By finding legal standards and rulings of relevant cases, this article will help readers in practical business to enhance the ability to apply the provisions to their contracts.

  • Purpose - The purpose of this study is to review and analyzes the contract of carriage and delivery/transport document in light of the major changes made to the Incoterms® 2020 rules forced into effect on January 1st, 2020. Design/methodology - This study analyzed responsibility for the loading and unloading of goods under the contract of carriage in Incoterms 2020® rules forced into effect by the ICC from January 1, 2020, and what document must be presented as evidence of delivery by the seller. Findings - A review revealed that in Rule C, the costs of unloading at the place of destination are determined by the terms of the contract of carriage, and in the DAP and DDP rules, if the seller bears the unloading costs, such unloading costs cannot be recovered from the buyer. To settle this issue, the seller needs to make a contract of carriage by sea with the carrier on FI terms. Furthermore, in the case of containerized goods that the FCA should be used, FOB was misused because the seller could not present an on-board bill of lading in the L/C transaction. However, it was confirmed that in FCA, the parties can use an optional mechanism to issue an on-board bill of lading. Originality/value - Incoterms 2020® rules are still widely used in international trade by parties to contract sales around the world, just like Incoterms 2010® rules. This study attempts to reduce or eliminate disputes that may arise from interpretative misunderstandings between the parties in the contract of sales concluded by the seller and the buyer.

  • Purpose - The letter of credit has been playing a major role to diminish overall risks which exist among concerned parties even though there are differences such as language, culture, law, and distance. This paper reviews essence of the letter of credit and its transaction principles, as well as overall practical questions based on the L/C transaction principle. It also investigates the risk of fraud occurrences in L/C transactions and the importance of fraud prevention and preventive measures in international L/C transactions, including the Fraud Rule, which is a major topic to consider in business transactions. Design/methodology - It is considered that an importing country's concerned parties and an exporting country's concerned parties face different situations. This study employs the existing framework to identify liability, responsibility, and obligation for all concerned parties across countries. Using a quite direct measurement of principles in the letter of credit, such as principle of independence, principle of abstraction, and principle of strictness and coincidence, we studied these differences. Findings - Our main findings can be summarized as follow. The paper enhances the efficiency of the L/C payment method to provide fraud generated from L/C transactions, presentation of a theoretical framework about fraud and fraud prevention, which international trading companies should acknowledge in a material way based on fraud risk resulting from taking advantage of L/C transaction principles. Originality/value - Existing studies focus on fraud accidents in L/C transactions by taking bad advantage of the characteristics of the letter of credit without suggesting risks of fraud. This paper attempts to evaluate and provide preventive measures as a solution for fraud and risky international business in a letter of credit transaction. This area of trade studies is underexplored, both empirically and theoretically, although the issue has long been important to Korean and world community foreign trade.

  • This study explains details on Heungbokjeon during the reconstruction of Gyeongbokgung Palace in the 19th century for the first time in 273 years. Hence, the construction of a palace with more than 7,000 Kan(間) made possible in a short stretch of time. Given the fact that its existing architecture was recycled. The antecedent of Heungbokjeon(興福殿) was the Hamiljae(咸一齋) of Changuiggung(彰義宮) which served as the residence of King Yeongjo before he was enthroned. On the other hand, the Changuigung was the outset of Inpyeongwi-gung(寅平尉宮), which was built for the princesses. During the reign of King Hyojong the princess who got married must depart from the Inpyeongwi-gung. This study corroborated the undertaking of modification of its architecture frombeing asymmetrical house to symmetrical most primarily the inner part of the palace through the innovation of Changui-gung and the restoration of Hamijae to Heungbokjeon. Hence, it was confirmed that the Heungbokjeon was the only inner part of the palace that was not burned down by the 2 consecutive fires during the reign of King Gojong, to be more specific these fire happend on his 10th and 13th year of rule. Consequently, the research process of Gyeongbokgung Heungbokjeon can escalate the possibility of considering not only the reconstruction of Gyeongbokgung in the 19th century, as well as the construction of the capital city in the 17th century.

  • Objective: Internal injuries and consumptive disease have different causes, yet they can affect each other. The relationship and combination of prescription drugs in the clinical practice of internal injuries and consumptive disease were analyzed for various diseases of "Donguibogam" through network analysis. Methods: The prescriptions used in consumptive disease and internal injury were established by conducting a full survey on the papers extracted from Donguibogam. The R version 4.0.3 (2020-10-10) and the igraph and arules package were used to perform network analysis and association rule relationship mining analysis in the first and second prescription compositions. Results: The herb frequently used for internal injury was Glycyrrhizae Radix, while the herb combination frequently used was Citri Pericarpium-Glycyrrhizae Radix. For centrality, the main factor was generally Glycyrrhizae Radix. In the case of consumptive disease, the herb most frequently used was Angelicae Gigantis Radix, and the combination most frequently used was Rehmanniae Radix Preparata-Angelicae Gigantis Radix. In terms of centrality, it was Angelicae Gigantis Radix. As a result of the network analysis of herbal prescription frequency, each group was divided into three. Conclusion: The interrelationship between internal injury and consumptive disease prescription drugs may reveal the differences and similarities between internal injury and consumptive disease and may serve as a basis for the development of new drugs or materials that can enhance mutual effectiveness in the treatment of internal injury and consumptive diseases.
