Purpose: Market basket analysis is one of the most frequently used methods in the retail industry today as a technique to discover the product association. It is empirically analyzed how these product associations differ regionally in the case of the United States. Research design, data, and methodology: Based on the purchasing data of consumer panels collected from 49 US states, the association rules for each state was extracted with the corresponding lift values indicating product association. The difference in lift values in 49 states by the association rule was compared and tested for 49 states and for 4 census regions (Northeast, Midwest, South, West). Results: The association rules of 3/4 of the same association rules show positive associations or negative associations depending on the lift values of the states. There were significant differences in the lift values for 49 states, and for 4 census regions. These significant differences in the lift values were found to be related to the distance between states and whether states belong to the same census region. Conclusions: Retail product associations shown by market basket analysis may vary depending on regional distance or regional heterogeneity. It is necessary to pay attention to these points in multi-store environment.

Recently, the recommendation system has attracted the attention of users as customized recommendation services have been provided focusing on fashion, video and music. But these services are difficult to provide users with proper service according to many different contexts because they do not use contextual information emerging in real time. When applied contextual information expands dimensions, it also increases data sparsity and makes it impossible to recommend proper music for users. Trying to solve these problems, our study proposed a music recommendation system to recommend proper music in real time by applying association rules and using relationships and rules about the current location and time information of users. The accuracy of the recommendation system was measured according to location and time information through 5-fold cross validation. As a result, it was found that the accuracy of the recommendation system was improved as contextual information accumulated.

In this paper, we proposed new outworn aircraft management procedure. ROKAF has both good management skill and information system, AMMIS, regarding aircraft maintenance based on all kinds of aircraft's defects. To optimize and secure aircraft's operation, management of the outworn aircraft is very important for ROKAF. With respect to these outworn aircraft's defects and maintenance, we analyzed defects occurrence pattern of outworn aircraft by using AMMIS data and Market Basket Analysis, and found the specified association rules for each defect. By using these association rules, we developed new management procedure for outworn aircraft based on the results of affinity analysis. The management procedure in this paper will also be used to optimal operation and maintenance of other aircraft and weapon systems.

So far, the evaluation of machine translation has used a numerical approach, but there is evidence that it is not sufficient to reflect the characteristics or behavior of machine translation users(Hutchins, 2007; Wu et al., 2016; Park et al., 2013). Therefore, this study focused on the purpose of use and purchasing behavior of machine translation users. At this time, the indirect comparison method introduced by Morgan and Hunt(1994) was used to measure cognitive gaps and analyze the purchasing behavior of users. According to the analysis of association rules using cognitive gaps, the smaller the cognitive gap, the more positive the purchase behavior. In addition, procedural knowledge derived from language knowledge is activated in situations involving responsibility, and in routine situations, procedural knowledge trained from pragmatic knowledge works.

The purpose of this paper is to introduce the arbitral proceeding system in Indonesia. Arbitration in Indonesia is governed by Law No. 30 of 1999 on Arbitration and Alternative Dispute Resolution (Arbitration Law). Also, the Indonesian National Board of Arbitration (BANI) is the main arbitration body in Indonesia. BANI handles both domestic and international disputes. BANI has published its Rules of Arbitral Procedure (the BANI Rules). Within a period of not longer than 30 days after receiving the petition for arbitration, the respondent must submit its reply. Also, if the respondent wishes to assert against the claimant a counter-claim in connection with the dispute, the respondent may submit such counter-claim together with its statement of defense no later than the first hearing. This paper suggests that the following may be some of the disadvantages to using arbitration under the BANI Rules. The first is that final decision or approval regarding the designation of all arbitrators shall be in the hands of the Chairman of BANI. It is the chief problem facing the international stream of arbitration systems. The second is that arbitrators must have certain minimum qualifications. BANI Rules provide the same requirements for the qualifications of the arbitrators as the Arbitration Law. The third is that the BANI Rules require arbitrators in BANI-administered references to be chosen from BANI's list of arbitrators. BANI can also consider a recognized foreign arbitrator if the foreign arbitrator meets the qualification requirements and is prepared to comply with the BANI Rules. This includes the requirement that the appointing party must bear the travel, accommodation, and other special expenses related to the appointment of the foreign arbitrator.

Incoterms 2010 Rules consist of 11 rules. The 11 rules are presented in "rules for any mode or modes of transport" and "rules for sea and inland waterway transport". The each rule of Incoterms 2010 rules has the guidance note, 10 articles(A1~A10) in relation to the seller's obligations and 10 articles(B1~B10) in relation to the buyer's obligations. The A6 and B6 of Incoterms 2010 rules, likewise previous Incoterms rules, have the article of allocations of costs. These articles of Incoterms 2010 rules provide the allocation of costs between the seller and the buyer. According to These A6 and B6, in principle, the seller must pay all costs relating to the goods until they have been delivered in accordance with A4, and the buyer must pay all costs relating to the goods from the time they have been delivered as envisaged in A4. The purpose of this paper is, therefore, to analyze the clauses of allocation of costs in Incoterms 2010 and to provide the problems of the clauses.

Purpose The purpose of this study is to develop a prediction model and decision rules for the elderly's suicidal ideation based on the Korean Welfare Panel survey data. By utilizing this data, we obtained many decision rules to predict the elderly's suicide ideation. Design/methodology/approach This study used classification analysis to derive decision rules to predict on the basis of decision tree technique. Weka 3.8 is used as the data mining tool in this study. The decision tree algorithm uses J48, also known as C4.5. In addition, 66.6% of the total data was divided into learning data and verification data. We considered all possible variables based on previous studies in predicting suicidal ideation of the elderly. Finally, 99 variables including the target variable were used. Classification analysis was performed by introducing sampling technique through backward elimination and data balancing. Findings As a result, there were significant differences between the data sets. The selected data sets have different, various decision tree and several rules. Based on the decision tree method, we derived the rules for suicide prevention. The decision tree derives not only the rules for the suicidal ideation of the depressed group, but also the rules for the suicidal ideation of the non-depressed group. In addition, in developing the predictive model, the problem of over-fitting due to the data imbalance phenomenon was directly identified through the application of data balancing. We could conclude that it is necessary to balance the data on the target variables in order to perform the correct classification analysis without over-fitting. In addition, although data balancing is applied, it is shown that performance is not inferior in prediction rate when compared with a biased prediction model.

The purpose of this study was to explore clusters of married woman based on family differentiation and family rules originating from their family of origin, and to examine family strength according to clusters. The research instrument comprised of a questionnaire completed by 269 married women that investigated family differentiation and family rules based on family origins, and the comparative strength of their nuclear family. Analysis of subgroups was based on four representative categories differentiating family rule patterns. Cluster analysis demonstrated that the higher family differentiation level and lower-mid family rules level were related to greater family strength. As a subgroup, lowest levels of family strength were associated with lower family differentiation and lower family rules in all clusters. Findings supported the efficacy of a typological approach for investigation of experiences of married women based on family origin.

The purpose of this study is to analyze the characteristics of Vietnam's arbitration system and to present measures that companies can utilize in practice. This research considers KCAB International Arbitration Rules, focusing on amendments to the Decree on Vietnam Commercial Arbitration Act and amendments to the VIAC Arbitration Rules. To sum up some features, the decree on the Commercial Arbitration Act simplified the registration procedures for arbitration centers and their branches and made the publication of court decisions and the recognition of the approval and execution of foreign arbitration courts, thereby enhancing transparency. First of all, the decree on the Commercial Arbitration Act simplified registration procedures for arbitration centers and their branches. In addition, the court strengthened transparency by officially announcing court judgments, recognition, and decisions. Next, there are some points to note in the arbitration rules of the VIAC. First of all, the rules of expedited procedure lack clarity. Next, parties should make a separate document for counterclaim and submit it with a statement of defense. In addition, the arbitral language may choose multiple languages by the Arbitral Tribunal unless the parties agree. Therefore, companies need to take a closer look at their understanding of the international arbitration system, which is mainly used in international disputes, and the characteristics of the Vietnamese arbitration system.
