The recent conflict between Russia and Ukraine underscores the significant of military logistics support in modern warfare. Military logistics support is intricate and specialized, and traditionally centered on the mission-level operational analysis and functional models. Nevertheless, there is currently increasing demand for military logistics support even at the engagement level, especially for resupply using unmanned transport assets. In response to the demand, this study proposes a task model of the military logistics support for engagement-level analysis that relies on the logic of ammunition resupply below the battalion level. The model employs a decisions tree to establish the priority of resupply based on variables such as the enemy's level of threat and the remaining ammunition of the supported unit. The model's feasibility is demonstrated through a combat simulation using OneSAF.

Startup must be agile and be able to handle extreme changes, survive unpredicted threats, and capitalize on emerging business opportunities. Agile teams continually sense changes for competitive action and marshal the necessary knowledge. While team members share their knowledge, there must be emerging various type of conflicts in teams. This study examines the relationship among the conflict, knowledge sharing and agility in startup context. At the same time, we tested the roles of shard vision both moderating variable between conflict and knowledge sharing, and antecedent for knowledge sharing. Different two types of conflict, task conflict and relationship conflict, knowledge sharing, agility, and different impact of shared vision are identified from literatures and tested. 182 data points were collected from under 5-year old startup's representatives to test these hypotheses. PLS data analysis indicated that the task conflict and shard vision positively effect on knowledge sharing, and then knowledge sharing has statistically significant effect on agility. And the impact of conlict has been weakened by shared vision's moderating effect. Based on the results, we proposed practically several team management skills for startup managers, leaders and stakeholder, and explained theoretical contributions.

Driven by the development of information technologies, information system (IS) use has been common even in military organizations. In particular, field artillery is currently using the Battalion Tactical Commanding System-A1 (BTCS-A1) to improve fire support. The use of BTCS-A1 makes fire-commanding processes simple and autonomous, which leads to shorten time to support fire. Although BTCS-A1 has been considered as a helpful system, there still exists some dispute regarding its effectiveness and impact on task performance. By conceptualizing BTCS-A1 use as appropriation, this study investigates how BTCS-A1 appropriation promotes task performance. We also hypothesize that IS quality, organizational pressure (institutional pressure and supervisor influence), and team climate (team learning climate and team empowerment climate) increase the appropriation. Survey results show that organizational pressure and team climate promote BTCS-A1 appropriation, which improves users' task performance. However, effect of IS quality is not significant. Theoretical and practical implications are presented.

In level 3 automated vehicles, drivers are expected to encounter transition of control when the system reaches its limit. Drivers need to refocus their attention on the road ahead and gain situational awareness. Appropriate information should be conveyed during this period in order to prevent human errors. In this paper, we defined the takeover process as 'in-the-middle-of-the-loop' and conducted Task Analysis and Work Domain Analysis to find out information requirements. As a result, we specified required information types and interface considerations. Moreover, we conducted an experimental study to find how the information types affect drivers on situation awareness, cognitive load and reaction time. Consequently, we found different information on system transparency should be conveyed depending on the urgency of takeover situation and driver guidance could help drivers with better situation awareness after the takeover.

This study attempted to analyze the jobs of early childhood special education teachers working in kindergarten's special classes using the DACUM technique. To this end, the DACUM Committee was formed with six early childhood special education teachers with extensive field experience. A total of six DACUM workshops were conducted to derive job definition, job descriptions, and job specifications. As a result, the job description of early childhood special education teachers consisted of 9 duties and 53 tasks, and the job specification consisted of 80 knowledge, 98 skills, and 22 attitudes. Early childhood special education teachers working in kindergarten's special classes were tasks differentiated from special education teachers working in elementary and secondary school including home-linked guidance, health and safety management, elementary school transfer guidance, environmental composition according to play topics, and indoor and outdoor play activities guidance. In the case of knowledge, the Special Education Act on the Disabled, etc. and knowledge on behavioral modification took precedence. Skill showed high frequency of observation-record, parental interviews and parental education skills. Attitudes as experts and administrators took priority. The results of this job analysis can help organize a curriculum to train early childhood special education teachers with high job competency in universities.

In this paper, university hospitals, general hospitals/hospitals, private clinics, Chinese medicine hospitals and clinics in Seoul. Metropolitan Inchon, Kyunggi-do were probed to find out how the variables of service task factor are related to customer satisfaction, and to find out the determinants of medical service task(tangible quality, flexibility, cost, time and managerial skills), and anticipation factors, and respective items of customer satisfaction through statistical analysis. The meaning of the above mentioned findings should be carefully understood and construed due to the following problems. Because the factors why patients select hospitals were measured limitedly. it cannot show everything I intended to suggest. Especially due to the insufficient number if items. customer satisfaction variables are too limited. Reflecting the developing changes in various medical environments, hospitals could meet the objective of maintenance and prosperity only by facing the competition effectively and satisfying patients. Also hospitals should pursue patient-oriented service management. In other words, a strategic management of service task factors is needed. Based on this paper's research. a further study should be conducted continuously in order to give customers more satisfaction.

For the empirical analysis in this study, 335 cabin crews from large airline companies and budget airlines were interviewed using self-reporting questionnaires. The data was analyzed using the SPSS 23.0 and AMOS 23.0. First, of the organizational culture types, the relationship-oriented culture, hierarchy-oriented culture, and task-oriented culture were found to have negative impacts on job stress. Second, the innovation-oriented organizational culture, relationship-oriented culture, and hierarchy-oriented culture were found to have positive impacts on empowerment. Third, empowerment was found to have a negative impact on job stress. Fourth, as for the mediating effect of empowerment, the innovation-oriented culture, relationship-oriented culture, hierarchy-oriented culture, and task-oriented culture were verified to be all significantly mediated by empowerment in their relationship with job stress. As a result, it was shown that cabin crews of airline companies found their work more fun, interesting, and valuable in an organizational structure that was more oriented toward flexibility, rather than the hierarchical, task-oriented cultures that are more focused on control and order. It was also found that empowerment was a mediating factor in the relationship between organizational culture and job stress.
