In the development of a production process scheduling system a collaboration method must be defined for the cooperation among submodules within the system. The blackboard architecture is exploited for solving the collaboration problem, which is one of the problem solving architecture that belongs to the distributed artificial intelligence. The dynamic states of the problem solving processes are presented in the hierarchically constructed shared working memory called as a blackboard. The communication for the collaboration is done through the blackboard. The problem solving steps are contained in the global controller, one of a component that consists the blackboard architecture, as knowledge. The global controller activates proper submodules based on the knowledge. By applying the blackboard architecture the collaboration problem among submodules in the grating production process scheduling system (GPSS) has been solved as well as the system became adaptable to the future modifications and expansions.

Objectives: This study was conducted to examine the length of exposure to smartphone and its association with dietary behavior toward snacks, lifestyle, and nutrition knowledge in elementary school students. Methods: Subjects were 372 5th and 6th grade schoolchildren in Cheongju, Korea, and data was collected by a self-administered questionnaire. They were divided into two groups by the time spent using smartphone: moderate (< 2 hours/day) and overexposure (${\geq}2$ hours/day). Data was analyzed using frequency analysis, ${\chi}^2$-test, and independent t-test as well as analysis of covariance when necessary. Results: Approximately half of subjects (41.4%) reported spending ${\geq}2$ hours/day using smartphone. That habit was more frequent among students in the 6th grade, those who received more monthly allowance, and who has a working mother. 63.4% of the subjects reported that they consumed snacks while watching television, using a computer and/or a smartphone and 48.1% said that they consumed snacks while they use a smartphone. Both situations were most prevalent among those with overexposure to smartphone (${\geq}2$ hours/day). We also observed that a higher percentage of subjects from the overexposure group spent more money on snack foods with the preference for ice cream, fast food, and carbonated drinks. Further, those in the overexposure group consumed more ice cream, cookies, and carbonated drinks. In addition, they had less desirable dietary behavior and health-related lifestyle (sleep duration and frequency of regular exercise) compared to those with moderate smartphone usage (< 2 hours/day). However, there was no statistical difference in nutrition knowledge among children with different degrees of smartphone usage. Conclusions: Our results showed that longer smartphone use was associated with less desirable snack preference/consumption and other dietary behavior in elementary school students. Thus interest and positive attitudes towards healthy snacks and diet should be reinforced in nutrition education programs, especially for those who are prone to use smartphones.

Workflow management system is a system that manages the workflow model which defines the process of work in reality. We can define the workflow process by sequencing jobs which is performed by the performers. Using the workflow management system, we can also analyze the flow of the process and revise it more efficiently. Many researches are focused on how to make the workflow process model more efficiently and manage it more easily. Recently, many researches use the workflow log files which are the execution history of the workflow process model performed by the workflow management system. Ourresearch group has many interests in making useful knowledge from the workflow event logs. In this paper we use XES log files because there are many data using this format. This papersuggests what are the cardinalities of the temporal workcases and how to get them from the workflow event logs. Cardinalities of the temporal workcases are the occurrence pattern of critical elements in the workflow process. We discover instance cardinalities, activity cardinalities and organizational resource cardinalities from several XES-based workflow event logs and visualize them. The instance cardinality defines the occurrence of the workflow process instances, the activity cardinality defines the occurrence of the activities and the organizational cardinality defines the occurrence of the organizational resources. From them, we expect to get many useful knowledge such as a patterns of the control flow of the process, frequently executed events, frequently working performer and etc. In further, we even expect to predict the original process model by only using the workflow event logs.

Objective: The increasing number of people living in high-rise apartments may result in a delayed response from emergency medical technicians called out for an out-of-hospital cardiac arrest, making the role of apartment managers as the first responders extremely important. This study investigated whether automated external defibrillator (AED) placement influences the willingness of apartment managers to perform cardiopulmonary resuscitation (CPR) and use an AED. Methods: A cross-sectional target population-based survey was conducted in Daegu, July 2016. Questionnaires were sent to apartment managers working in apartments with more than 500 households. The general characteristics of the respondents, status of CPR education, and knowledge about and willingness to perform CPR and use an AED were investigated. Results: Of the 1,445 respondents, 758 (52.5%) worked in apartments with AEDs, of which 77.8% and 70.8% were willing to perform CPR and use an AED, respectively, compared with 68.1% and 60.0% of respondents who worked in apartments without AEDs. After adjusting for potential confounders, AED placement was associated with the willingness to perform CPR (odds ratio [OR], 1.33; 95% confidence interval [CI], 1.04-1.71) and use an AED (OR, 1.39; 95% CI, 1.10-1.75). Prior CPR training and accurate knowledge of CPR skills were also associated with the willingness to perform CPR and use an AED. Conclusion: Placing AEDs in high-rise apartment buildings and providing refresher CPR education for maintaining CPR skills will be necessary to support apartment managers in their role as first responders.

The purpose of this study is to verify the correlation between leader's machiavellianism and turnover intention. To this end, we tried to investigate the overall mechanism of the research model through the mediating effect of hindsight bias. To verify the hypothesis, surveys were conducted twice with 335 employees working at companies with more than 300 employees in various occupations. As a result of the study, first, it was found that the machiavellianism of the leader had a positive significant effect on the employee turnover intention. Second, it was found that hindsight bias had a positive significant mediating effect between the leader's machiavellianism and employee turnover intention. It can be inferred that the higher the machiavellianism tendency of the leader, the higher the hindsight bias is experienced and the negative impact on the effectiveness of the organization, the higher the employee turnover intention. Therefore, this study in-depth verifies the mechanism between the leader's machiavellianism, hindsight bias, and employee turnover intentions, suggesting new implications from a perspective different from the existing research flow, and suggesting future research tasks and limitations on the role of leaders.

Purpose: The purpose of this study is to identify the effects of organizational commitment (OC) and perceived patient safety culture (PPSC) on patient safety nursing activities (PSNA) among nurses in comprehensive nursing care units. Methods: Participants were 173 nurses working at five general hospitals in Chungcheong area. Data were analyzed using descriptive statistics, 𝑥² test, t-test, ANOVA, Pearson's correlation coefficient, and multiple regression analysis with SPSS/WIN 23.0 programs. Results: The mean scores of the OC and PPSC were 3.28±0.50 and 3.85±0.35, respectively. The mean score of PSNA was 4.55±0.41, and PSNA was significantly different by the experience of participating in hospital's safety culture campaigns (t=2.70, p=.008). The results of the multiple regression analysis showed that 'patient safety knowledge and attitudes' (β=.27, p=.006) and 'unpunished environment to error' (β=.22, p=.004) as the sub-categories of PPSC were affecting factors on PSNA with an explanatory power of 26.0% (F=6.40, p<.001). Conclusion: The results of this study suggest that in order to promote PSNA among nurses in comprehensive nursing care units, it is necessary to develop a program to enhance patient safety-related knowledge and attitudes. In addition, the hospital's organizational efforts such as operating safety campaigns and creating an unpunished environment to error should be needed.

In this paper, we propose a standard AI developer job training track based on industry needs. The characteristic of this curriculum is that it can minimize the mismatch of AI developer job competency between industries and universities. To develop an AI developer job training track, a survey will be conducted for AI developers working in industrial fields. In this survey, among the five NCS-based AI developer jobs, job analysis is conducted by deriving AI developer jobs with high demand for manpower in industrial fields. In job analysis, the core competency unit elements of the job are selected, and knowledge, skills, tools, etc. necessary to perform the core competency unit elements are derived. In addition, a standard AI developer job curriculum is developed by deriving core subjects and road-map that can educate knowledge, skills, tools, etc. In addition, we present an efficient AI developer job training method using the standard AI developer job training course proposed in this paper.
