Purpose - Owing to economic development and rapid globalization, the number of people traveling abroad has increased dramatically in recent years. For instance, according to data from World Tourism Organization, approximately 1,724 million tourists traveled abroad in 2016. This phenomenon has resulted in a change for domestic markets, as they no longer serve only domestic customers but also serve foreign customers as well. Therefore, intercultural service encounters between services providers and customers from diverse cultural backgrounds are becoming more frequent. Especially in the field of retailing, salesperson's customer oriented selling behavior is particularly important for the successful interactions. However, it is hard to find some factors that can improve salesperson's customer oriented selling behavior in intercultural sales encounters. Research design, data, and methodology - A quantitative survey methodology was utilized to collect data on 312 salespeople at duty-free shops located on Jeju Island, Korea. As a tourism-based region, Jeju Island has attracted a large number of foreign tourists since being designated as an international free city in 2002. Owing to this phenomenon, intercultural sales encounters between salespersons and customers from different cultures have become commonplace. Compared to other salespeople, salespeople working in duty-free shops have more frequent intercultural interactions, as over 90% of their total customers are from foreign countries. Additionally, regular professional training programs for salespeople help cultivate cultural intelligence. Data analysis was conducted using SPSS 20. Results - This paper explores the role of empathy and cultural intelligence in intercultural sales encounters using a theoretical model incorporating the causal relationships between empathy(cognitive empathy and emotional empathy) and customer oriented selling behavior, as well as the moderating effects of cultural intelligence in these relationships. Conclusions - This study is almost the first to explore the influence of empathy and cultural intelligence in intercultural sales encounters. Thus, this study provides a meaningful contribution to the application of empathy and cultural intelligence in the retailing field and will draw the attention of personal distribution practicers and researchers to the importance of empathy and cultural intelligence. Additionally, this study has useful managerial implications for employee selection, training, and development in retailing firms engaged in intercultural sales encounters.

The purpose of this study is to improve bankruptcy prediction models by using a novel hybrid under-sampling approach. Most prior studies have tried to enhance the accuracy of bankruptcy prediction models by improving the classification methods involved. In contrast, we focus on appropriate data preprocessing as a means of enhancing accuracy. In particular, we aim to develop an effective sampling approach for bankruptcy prediction, since most prediction models suffer from class imbalance problems. The approach proposed in this study is a hybrid under-sampling method that combines the k-Reverse Nearest Neighbor (k-RNN) and one-class support vector machine (OCSVM) approaches. k-RNN can effectively eliminate outliers, while OCSVM contributes to the selection of informative training samples from majority class data. To validate our proposed approach, we have applied it to data from H Bank's non-external auditing companies in Korea, and compared the performances of the classifiers with the proposed under-sampling and random sampling data. The empirical results show that the proposed under-sampling approach generally improves the accuracy of classifiers, such as logistic regression, discriminant analysis, decision tree, and support vector machines. They also show that the proposed under-sampling approach reduces the risk of false negative errors, which lead to higher misclassification costs.

For effective improvement of water quality in Seokmun reservoir, this study implemented various analyses including the tributary water quality and flowrate monitoring, contamination of sediment, investigation of pollution source, selection of priority management target tributary by stream grouping method. The COD concentration of the majority of tributaries in Seokmun reservoir watershed was relatively higher than BOD concentration. The concentration of water pollutants regardless of water quality parameters in Yeokcheon, Dangjincheon, Sigokcheon, Baekseokcheon, small stream in Jinkwanri and Janghangri were higher than the other tributaries. The pollution sources in the Seokmun reservoir watershed were mostly distributed in the population, livestock, and industry. The pollutants, which located in Yeokcheon, Dangjincheon, Baekseokcheon, and small stream in Janghangri selected as priority management target tributary, should be preferentially reduced for improving the water quality in Seokmun reservoir. As the evaluation results of water quality in Seokmun reservoir for the effect of water quality improvement according to various scenarios using water quality model, it was found that the water quality in Seokmun reservoir due to the construction of a wastewater treatment plant for management of pollutants in the watershed would be satisfied the class V of water environment standard in reservoir.

The key word (KW) is a set of words to clearly express the important causations of marine accidents; they are determined by a judge in a Korean maritime safety tribunal. The selection of KW currently has two main issues: one is maintaining consistency due to the different subjective opinion of each judge, and the second is the large number of KW currently in use. To overcome the issues, the systematic framework used to construct KW's needs to be optimized with a minimal number of KW's being derived from a set of Common Words (CW). The purpose of this study is to identify a set of CW to develop the systematic KW construction frame. To fulfill the purpose, the word reduction method to find minimum number of CW is proposed using P areto distribution function and Pareto index. A total of 2,642 KW were compiled and 56 baseline CW were identified in the data sets. These CW, along with their frequency of use across all KW, are reported. Through the word reduction experiments, an average reduction rate of 58.5% was obtained. The estimated CW according to the reduction rates was verified using the Pareto chart. Through this analysis, the development of a systematic KW construction frame is expected to be possible.

Recently the biometric recognition technology is intensively studied and the standardization of the technology has been highly demanded for its commercialization. Currently many blometric recognition products are being developed based on the BioAPl(Biometric Application Program-ming Interface) specification. However, the reliable testing tools (or scenarios) to evaluate performance and conformance of the products are not shown yet. In this paper, a conformance testing method is presented, which verifies a biometric recognition system to meet the requirements of the BioAPl standard. Two different testing procedures are used in the proposed method. The first procedure evaluates that each functions offered in the BioAPl specification are correctly implemented and that the functions are actually used in the system. Through the Procedure, a BSP(Biometric Service Provider) system is executed on the framework of the BioAPl functions. It requires selection of parameters and prece-dent functions that should be executed first. The second procedure evaluates the abilities of module management, handling operations and ver-ification process by the analysis of the test cases. It tests the correctness of the system operation when a testing scenario is given. The proposed testing method is applied on a fingerprint verification BSP using the sample BSP provided by the BioAPl consortium. The experimental results shows the benefits of the proposed testing method.

The aim of this study was to describe the self-esteem, appearance satisfaction, and job-seeking stress and to investigate the effects of self-esteem and appearance satisfaction on job-seeking stress in nursing and healthcare related students. A total of 515 third and fourth year graduate students were included in this study. The data were collected between May 2 and May 13 of 2016 and analyzed using t-test, ANOVA, Scheffe's test, Pearson's Correlation Coefficient, and multiple regression with SPSS 19.0. The economic state had an influence on self-esteem, appearance satisfaction, and job-seeking stress; however, the motive of application and decision of the department of selection did not have any influence. A positive correlation was found between self-esteem and appearance satisfaction. Moreover, job-seeking stress was negatively correlated with both self-esteem and appearance satisfaction. The strongest predictor of job-seeking stress was self-esteem. Self-esteem, employment-area, satisfaction with major, and college majors accounted for 24.4% of job-seeking stress based on multiple regression analysis. These findings indicate that it is necessary to develop a program that would increase self-esteem and satisfaction with major and decrease job-seeking stress according to college majors and employment-area in nursing and health care related students.

This study was conducted to investigate the trends in domestic and international disaster-related research through a systematic review of the literature and to establish a basis for future disaster-related countermeasures and development directions. A related literature search was conducted through the domestic and foreign databases through the combination of disaster-related terms from 2000 until February 28, 2017, and 79 articles were used in the analysis based on selection and exclusion criteria of 177 total documents. As a result of the research, 31.6% of disaster research type was quantitative studies, and 29.1% of the major disciplines were medical research. In addition, there were engineering(18.9%), public administration(13.9%), and nursing(11.4%). In foreign literature, there are many triage studies for the classification of patients in multiple lesions. On the other hand, only 30.4% of total triage studies in Korea were detected. Most of them were related to triage development, triage evaluation, triage research, and reviews. In addition, according to the disaster nursing capacity framework of the International Council of Nurses, 72.3% of studies were related to the response phase. Future research on disasters requires interdisciplinary convergence, patient classification, and technology integration to improve the survival rate of multiple injuries, and an integrated system based on the results of collaborative research among interdisciplinary groups is needed.

The selection of the support system is an important design parameter in design and construction of the tunnel using the new Australian tunnel method. It is a common practice to select the support based on the rock mass grade, in which the rock mass is classified into five rock groups. The method is applicable if the characteristics of the rock mass are uniform in the direction of tunnel excavation. However, such case is seldom encountered in practice and not applicable when the properties vary along the longitudinal direction. This study performs comprehensive three dimensional finite difference analyses to investigate the ground deformation pattern for cases in which the rock mass properties change in the direction of the tunnel axis. The numerically calculated displacements at the tunnel crown show that the displacement is highly dependent on the stiffness contrast of the rock masses. The results strongly indicate the need to select the support type $0.5{\sim}1.0D$ before the rock mass boundary. The paper proposes a new guideline for selecting the support type based the results of the analyses.

The purpose of this study was to develop a rapid and effective method of laser-induced fluorescence analysis for thrace amounts of Sm, Eu and Tb in nuclear fuels. The features of the method are the use of the distinct fluorescence wavelengths and the discriminative lifetimes of the respective elements when excited by a pulsed nitrogen laser. Fluorescence signals of the three elements were isolated by adequate selection of the filters or complexing agents (HFA, TTA) or discriminative delay and gate times in the signal processing circuit. It was found that S $m^{+3}$ and E $u^{+3}$ emitted strong fluorescence in the two complexing agent solutions or HFA and TTA. But in the case or T $b^{+3}$, the fluorescence signal was detected only in HFA solution. With respect to the concentrations of S $m^{+3}$, E $u^{+3}$ and T $b^{+3}$, the fluorescence signal intensities gave superior linearities in the range of 5 ppb-10 ppm for S $m^{+3}$, 0.5 ppb-1 ppm for E $u^{+3}$, and 0.1 ppb-300 ppb for T $b^{+3}$, The detection limits obtained were 5 ppb for S $m^{+3}$, 0.1 ppb for E $u^{+3}$, and 0.01 ppb for T $b^{+3}$, respectively.
