Care services are a significant asset in human life. Care in its overall nature focuses on human needs and covers several aspects such as health care, homes, personal care, and education. In fact, care deals with many dimensions: physical, psychological, and social interconnections. Very little information is available on estimating the cost of care services that provided to orphans and abandoned children. Prediction of the cost of the care system delivered by governmental or non-governmental organizations to support orphans and abandoned children is increasingly needed. The purpose of this study is to analyze the care cost for orphanage organizations in Saudi Arabia to forecast the cost as well as explore the most influence factor on the cost. By using business analytic process that applied statistical and machine learning techniques, we proposed a model includes simple linear regression, Naive Bayes classifier, and Random Forest algorithms. The finding of our predictive model shows that Naive Bayes has addressed the highest accuracy equals to 87% in predicting the total care cost. Our model offers predictive approach in the perspective of business analytics.

Objectives : This study aims to diachronically examine the classification systems of all materia medica, followed by categorization and analysis of each category to deduce each category's characteristic. This will provide foundation for further examining classifications of bencao in contemporary herbology. Methods : Classification systems from a total of 93 bencao related texts were collected and categorized. Each category's classification system was analyzed to determine its meaning. The classification systems were compared from a diachronic perspective, to further deduce each system's problem from a historical context. Results : The classification systems of materia medica could be summarized as following three standards: quality, origin, and medical application. In reality, bencao could be generally classified according to origin and medical application. The origin-based classification system provided a stable and flexible classification outline in the expansion process of bencao. The medical application-based classification strengthened the relationship between bencao and illness pattern, improving clinical applicability. Conclusions : In the history of herbology, the two classification systems created the current of herbology through mutual contribution and conflict. We hope that further discussion on the direction towards which classification system of bencao in contemporary herbology should head will proceed based on this study.

Remarriage has been prevalent in Korea since the mid-1990s. Remarried families have reported that they face many challenges and difficulties. Life for those who remarry can worsen when the children from a previous marriage live together with new family members. It is interesting that some remarried families adjust well while others do not. This study focuses on developing a practice model for strengthening the resilience of remarried families with children based on a literature review. To understand and support remarried families, the resilience perspective was chosen, focusing on a strengths perspective with developmental, ecological, and preventative perspectives. In terms of resilience, the proposed practice model was developed on the basis of three concepts: belief systems, organizational patterns, and communication. The model can be used to help remarried families accomplish adequate integration by growing as a new family and can prevent another divorce. Moreover, it can assist practitioners and policy-makers develop programs and policies with a strengths perspective rather than a deficit or problem-oriented perspective. Based on the model, various programs need to be developed to strengthen the resilience of remarried families. The development of supportive programs is suggested. These can include remarriage preparation programs, remarriage life education programs, interactive web-based programs, and family camps. For a long time, remarried families have been labeled as abnormal and atypical owing to the normal family myth. This negative perception of remarried families must be altered so that they are accepted with a positive outlook in a society. For further studies, the development of diverse supportive adaptation programs for various types of remarried families and active research on them are recommended. The practice model can assist with the adaptation and growth of remarried families by strengthening their resilience.

The purpose of this study is to examine the determinants of union commitment and union participation intention based on the social exchange perspective and apply implications to union setting to improve union management. The results are as follows : Firstly, union commitment is the most direct predictors of union participation intention and mediates the relation both perceived union support and union instrumentality and union participation intention. Secondly, both perceived union support and union instrumentality are direct predictors of union commitment but perceived union support has more effect than union instrumentality on union commitment. Lastly, process related justices affect on perceived union support but interactional justice is a more Important antecedent of perceived union support than procedural justice. Unexpected finding is that union instrumentality has direct relationship with not only union commitment but also perceived union support. This finding is needed further research in the future.

The rise in recent technology has changed the ways, in which people communicate with one another. Social networking services (SNSs) have become one of the most representative means. General SNSs allow users to create their own unique profiles, search for fellow members, share information, etc., while other SNSs have functions that cater to different needs of users. As a result, users of SNSs have begun to pick and choose different SNSs and concurrently use multiple SNSs in order to fulfill all their needs. This exploratory study examined which SNSs are used together and the characteristics that predict the use of multiple SNSs. In addition, it observed the differences between consumers' usage of multiple SNSs in different cultures. An online survey was administered to SNS users in the United States and Korea. The results of the study showed that the use of multiple SNSs is not yet prevalent in Korea, the country that represented a collectivistic culture. In addition, in the U.S., the highest number of users reported that they were active on at least three SNSs.

Background: In a safety perspective, efficient knowledge management is important for learning purposes and thus to prevent errors from occurring repeatedly. The relationship between knowledge exchange among employees and safety behavior may be of particular importance in distributed organizational systems where similar high-risk activities take place at several locations. This study develops and tests hypotheses concerning the relationship between knowledge exchange systems usage, knowledge exchange in the organizational system, and safety compliance. Methods: The operational context of the study is petroleum drilling and well operations involving distributed high-risk activities. The hypotheses are tested by use of survey data collected from a large petroleum operator company and eight of its main contractors. Results: The results show that safety compliance is influenced by use of knowledge exchange systems and degree of knowledge exchange in the organizational system, both within and between units. System usage is the most important predictor, and safety compliance seems to be more strongly related to knowledge exchange within units than knowledge exchange between units. Conclusion: Overall, the study shows that knowledge management is central for safety behavior.

The amount of data a related to a person is so substantial that it appears that a digital version of them can be built thereon. They are usually handled as personal information, and the attempts made to understand personal information have led to bundling and unbundling of various data, yielding numerous fragmented categories of personal information. Therefore, we attempt to construct a generalizable lens for a deeper understanding of person-related data. We develop a theoretical framework that provides a fundamental method to understand these data as an entity of a digitally represented person based on literature review as well as the concepts of inforg and infosphere. The proposed framework suggests person-related data consist of three informational inforg dimensions that can preserve the archetype of a person, form, content, and interaction. Subsequently, the framework is examined and tested through several analyses in two different contexts: social media and online shopping mall. This framework demonstrates the suggested dimensions are interrelated with certain patterns, the prominent dimension can determine the data characteristics, and the dimensional composition of data types can imply the characteristics of the digitally represented person in certain contexts.
