Inappropriate antibiotic use significantly contributes to antibiotic resistance, resulting in reduced antibiotic efficacy and an increased burden of disease. The objective of this study was to investigate the characteristics of prescribers whose antibiotics use was high and to explore factors affecting the use of antibiotics by medical institutions. This study analyzed the National Health Insurance claims data from 2015. Antibiotic prescription data were analyzed in terms of the number of defined daily doses per 1,000 patients per day, according to the World Health Organization anatomical-therapeutic-chemical classification and methodologies for measuring the defined daily dose. We investigated the characteristics of prescribers and medical institutions with high antibiotic use. Multivariate regression analyses were performed on the basis of characteristics of the medical institution (number of patients, type of medical institution [hospital or clinic], age of the physician, etc.). The number of patients and number of beds were found to be significant factors affecting antibiotic use in hospitals, and the number of patients, region, and medical department were significant factors affecting antibiotic use at the level of medical institutions. These findings are expected to help policy-makers to better target future interventions to promote prudent antibiotic prescription.

NOTAM is an announcement that is distributed to flight attendants with status information related to aviation. ICAO, the International Civilian Aviation Organization, recommends that a NOTAM service be provided for the SBAS service in order to use the SBAS signal-based access procedure. To comply with ICAO recommendation, KASS must provide NOTAM service to all aircraft landing using SBAS signal in order to provide APV-I SoL service. Therefore, it is necessary to develop KASS NOTAM system to provide KASS NOTAM service. In this paper, we analyzed the regulations related to NOTAM in Korea and abroad and analyzed the present state of NOTAM service in Korea. Based on this, we propose a method of providing KASS NOTAM service. We analyzed the NOTAM system of WAAS in the US and EGNOS in Europe and analyzed the main functional requirements of the KASS NOTAM system.

In sports, the proportion of data analysis in team management such as team strategy planning and marketing is increasing. In KBO(Korea Baseball Organization) league, in particular, plans such as recruiting players and fostering players are established to devise team strategies for the next year, such as FA and trade, at the end of a season. For these reasons, it is very important to predict players' performance for the next year. In this study, the target was limited to only the batter and tried to find out how to predict whether the performance of the next year will improve. As a standard record for rising and falling, OPS(On-Base Plus Slugging), which is easy to calculate and has a high relationship with team score, was used. In this study, 40 years of regular season data from 1982 to 2021 were used as data, and 11 machine learning classification models were used as experimental methods. Predicting the rise and fall of OPS, RBF SVM, Neural Net, Gaussian Process, and AdaBoost were more accurate than other classification models, and age did not significantly affect accuracy.

This study draws on a sociopolitical perspective to investigate the possible impact of champion leadership by project leaders on project viability(resource supply and organizational support) and team members' team efficacy by analyzing the empirical data of 92 ongoing projects collected from 22 public and private R&D institutes in the electronics, telecommunication, machinery, and chemical industries. Results revealed that higher level of project championing by project leader tended to positively related to a high level of organizational support and resource supply. It was also found that teams members who experienced higher level of project championing by project leader tended to have higher team efficacy. Furthermore, project type and innovative climate moderate the champion leadership-project performance relationships. The results found in this study offer several theoretical and managerial implications. First, champion leadership by project leaders is quite helpful to get more moral support and legitimacy of the organization for the project, and thus for acquisition of more tangible and intangible resources required for successful implementation of the R&D project. Champion leadership by project leaders also impacts the morale and self-confidence of the team members. Project leaders gives a sense of purpose and meaning to project members by actively and enthusiastically promoting the project, and by expressing confidence in team members' capabilities to perform a given task. In addition, his or her soliciting assistance and additional resources can contribute the building the confidence of members that the project can be performed well. Second, the relationship between champion leadership and project performances is context-specific (i.e., project type and innovative climate). This study is one of the few to have tested the moderating effects between champion leadership and project performances with a empirical research design. This study extends the current knowledge on champion leadership in the innovation process by generalizing their importance in R&D projects to a new industrializing context, Korea, and further sheds light on the contingent relationship between champion leadership and project performances in the innovation process. Based on these findings, some areas for future research are discussed.

The improvement of the reliability of weapon systems and the reduction of the total life-cycle cost based on the improving of the DT&E system for Company Organized weapon systems research and development are urgently required. The major advanced countries operate test and evaluation centers for military (U.S.), manage a large scale organization of IPT personnel (England) or conduct management of DT&E through a third party organization (France). Based on a survey of experts, an improvement of the DT&E policy in terms of reliability and objectiveness is needed, and management through a third party national defense agency and civilian agency such as the Surion development case is required. In addition, although it appears that efficiency improves when management of DT&E is performed by national defence agencies rather than civilian agencies, it is necessary to proceed by selecting a civilian agency based on competition in the case that it is difficult to select a national defence agency.

This research focuses on the IS development methodology as an object of innovation in an IS organization. It has two main research objectives. It was intended to understand the critical affecting factors which have an effect on the processing of each level in the dynamic and evolving innovation process. There are two levels of innovation process: initiation and implementation. It was also intended to understand the performance of IS organizational innovation. We found three main results by the LISREL analysis. First, main factors affecting initiation level of innovation are innovative tendency of IS members, communication level of IS organization, existence of champion manager, IS performance gap, executive supporting to IS, and relative advantage of IS development methodology. At the implementation level, it was understood that the existence of champion manager, executive support, and relative advantage of IS development methodology were the main factors promoting to use the innovation, and the complexity of innovation was a negative factor adopting the usage of innovation. Second, the quality of the previous level in the gradual innovation activities gives very notable affection to the continuous next level. Finally, it was found that the qualitative performance like the documentation, collaborative team approach, IS developer's awareness and ability corresponding to their task and so on was improved due to the IS organizational innovation. This research provides the standard framework for the IS organizational innovation in a structural way. In the practical aspect, it may be used as the principle for introducing and using the IS development methodology.

This study is to introduce a comprehensive framework of a crisis management system developed at a prominent hospital in South Korea. Throughout recent decades, especially in the recent years, the way in which to cope with both internal and external challenges has been one of the most critical issues. Since the incident management system in the U.S. is acknowledged as the most advanced crisis management model in the world, a portion of this study refers to the Hospital Incident Command System(HICS) provided by the California Emergency Medical Services Authority(EMSA). Nevertheless, the framework suggested in this article was designed based on a distinctive Korean hospital setting. The main contents of this study are as follows; categorization of each type of crisis, organization of a crisis management team in a non-crisis or crisis state, crisis assessment by life cycle stage, and establishment of crisis management protocol. Even though many types of crises are unspecified, those can be categorized into external crisis, medical crisis, and utility & activity failure. A crisis management organization should be operated and consisted differently- depending on a crisis or non-crisis situation. From a life-cycle perspective, the range by which the crisis should be managed extends from pre-stage to post-stage of the crisis. It is important to set proper scenarios and manuals by crisis type to develop a crisis management framework of high quality. With continuous efforts, hospitals can prepare for the uncertainty to better concentrate on core business operations.
