Objectives: The purpose of this study was to evaluate the opinions of hospital managers on DRG pilot study. Methods: Managers of 800 hospitals which had participated in DRG pilot study during the period 1997-1999, were requested to respond to structured self-administerd questionnaire. The questionnaire was composed with six categories: the motivation and satisfaction for the DRG pilot study, the opinions on the level of unit price, the appropriateness of DRG classification, the change of medical service quality during the pilot study, the patient's complains resulted from DRG system. and the opinions on the nation-wide application of DRG system. Results : Of the 800 subjects, 327(clinic, 210: 25 hospitals, 82 general hospitals, and 16 tertiary hospitals) completed the questionnaire, and the overall response rate was 41%, 121 hospitals(27%) answered that they participated in DRG pilot study because of convenience of claims and 118 hospitals(35%) dissatisfied with DRG system. 251 hospitals(85%) thought that the level of unit price under the DRG system was same as or lower than that of fee-for service. 297 hospitals(92%) responded that DRG classification should be modified and 137 hospitals(47%) experienced deterioration of medical service quality during the DRG pilot study. The 116 hospitals(35%) experienced the patient's complains resulted from DRG system. The 85 hospitals(88%) didn't want nation-wide application of DRG system. Conclusion: Most of the responded managers seemed to have negative opinions on DRG pilot study, even though they had been participated voluntarily. Further studies and extensive evaluations of DRG reimbursement system are needed before nation-wide application.

Recently, the issue of maintaining pilot competency has emerged as one of the major challenges in the aviation industry due to irregular schedules and flight intervals caused by the global COVID-19. Therefore, a survey was conducted on airline pilots to determine how stressed they would be when returning to their flights after experiencing irregular schedules or long-term furloughs. The level of stress that pilots receive due to flight intervals was divided into periods, and correlation with general characteristics was identified to see what emotional burdens exist as the lengths of flight interval increased. As a result, burdened flight intervals and the Pilot Flying(PF) intervals were identified as a statistically significant variables. In the case of the Pilot Flying interval, the level of stress was confirmed to be worse as the flying interval was elongated, and in the case of the burdened flying interval, the tendency of the stress index were lower as the period increased. Through this study, pilots who experienced reduced flight times were found to be accompanied by considerable amount of emotional burden proportionate to the length of the interval period.

Purpose: Women are more vulnerable to post-traumatic stress (PTS) than men, causing several health problems. Nurses should understand and work with women who have experienced trauma and provide interventions to promote their physical, social, and mental health. Methods: This quasi-experimental pilot study used a one-group pre-test/post-test design. Data were collected from 14 women recruited between December 2019 and May 2020 from a self-sufficiency support center in South Korea for sexually-exploited women who had experienced trauma. The program consisted of six one-on-one intervention sessions per week for six weeks. Each session averaged 60~120 minutes. Participants were assessed at pre-test, post-test, and one-month follow-up. Changes in outcome variables over time were analyzed using the Wilcoxon signed-rank and Friedman tests. Results: The caring program for health promotion was divided into six sessions: understanding the self, sharing traumatic events and negative emotions, reframing the meaning of traumatic events, identifying thoughts and physical and emotional responses, developing health promotion activities, and maintaining a positive attitude during the process of change. As a result of the caring program, PTS (F = 36.33, p < .001), depression (F = 24.45, p < .001), health-promoting behaviors (F = 7.06, p = .004), and self-esteem (F = 19.74, p < .001) among the participants differed significantly at pre-test, post-test, and follow-up. Conclusion: This study provides foundational information for the implementation of a theory-driven program by nurses in clinical and community settings to provide comprehensive care for women who have experienced trauma.

An increase in the number of retiring experienced pilots as well as drastic graying of new pilots will raise the problems on deepening imbalance of supply and demand of pilots over the next 7 years, which could entail fatal problems for the safety of harbour pilotage. In this study, the improvement plan of legal system to ease imbalance between supply and demand of pilots and help secure more experienced pilots has been proposed. A current state survey and analysis, statistical analysis, questionnaire survey on foreign countries, in-depth consultation with experts, etc., were all carried out to support this research. The conclusions of this study are, firstly, to propose an amendment that the minimum requirement of 5 years of seagoing service as a master to sit for the pilot exam should be relaxed to 2 years(which must include at least 1 year of master's seagoing service within the most recent 5 years) but the minimum requirement of 1 year of pilotage service should be reinforced to 1 year and 6 months to obtain a higher class of pilot certificate. Secondly, it is proposed that an amendment offering an additional 1 point per year over the minimum period of 2 years of seagoing service as a master should be added, with a maximum of 10 points in order to rationalize the additional incentive point system. In order to secure experienced pilots and resolve the legal conflict between the certificate revalidation system and the retirement system, it is also proposed that an amendment be passed revoking the retirement system and limiting the validity of any new certificates only to 68 years of age when issuing or revalidating a certificate, if an applicant is over a certain age. Promotional work, such as collecting opinions from interested parties and generating positive public awareness, should be carried out in the future. It will also be necessary to conduct a study on the training pilot exam system.

The Unmanned Air Vehicle (UAV) systems are indispensable tools of air surveillance and reconnaissance nowadays. Via this systems, hazardous end risky intelligence gathering activities are handled easily. Although they are named as "Unmanned" the UAV systems are commanded by pilots/operators. So, because of weather conditions, enemy attacks etc. as well as pilot error it is possible to face with sudden Round per Minute (RPM) drops and subsequently engine cut/stop during a mission flight at high altitudes. In this case, there are some very urgent decisions to make and rapid "emergency procedure" steps to take in a very short time before Line of Sight (LOS) is lost. The time before crash and the distance to landing air base need to be calculated, the Return Home route need to be checked and the landing/crash side need to be determined. Therefore it is a vital necessity that UAV pilots have some extra qualifications like being determined, well instructed and trained, experienced apart from operating ability. Within this scope, for an education process of a UAV pilot experience sharing and lessons learned are as important as simulators even more. By means of lessons learned it is possible to find out the reasons, mistakes and prevent the likely UAV accidents. In this study it is told about a real UAV crash, experienced of the pilot, the dos and don'ts and the difficulties. Thus it is aimed to help the people who can experience the same or similar situations in future.

The purposes of this study were to investigate the perception and needs of community nutrition programs for 379 community residents of 23 health centers where the pilot community nutrition programs are intervening. The awareness rate of the nutrition programs was 54.3% and the reason of the awareness was mainly happened to know when visiting health centers'. More than 90% of the respondents responded that public health nutrition services are necessary. But the residents who experienced the nutrition services showed higher needs of the programs(97.3%) and improved the impression about the roles of health centers(93.6%). They also showed a higher rate of balanced dieting, stronger intentions to change their inappropriate eating style and a higher practicing rate. The more they believed in the provided nutrition information, the more they showed concerns about their diet and practicing rate of the advices from nutritionists. These results show the positive and successful impact of the pilot nutrition programs on the community residents. We need strategies for a more active improvement of the programs and to maintain more qualified public health nutritionists to carry out targeted community nutrition programs.

Flight safety in modern commercial aircraft depends on the ability of pilots to manage overall flight operations. ICAO has made it mandatory for airlines to adhere to Crew Resource Management(CRM) policies to reduce operational safety threats. CRM is a set of techniques designed to effectively manage the human resources, aircraft, and environmental factors in order to promote safety and enhance efficient air operations. When looking at the career backgrounds of new pilots joining the Republic of Korea's commercial airlines, discharged military fighter pilots represent the largest demographic. Fighter pilots are experienced in empowering leadership and directive leadership from their military training and culture. New commercial airline pilots with military fighter pilot training should effectively acquire the required civil aviation CRM skills. The present study has been carried out to determine how the leadership experience of this demographic affects the acquisition of CRM skills for commercial airlines, and it confirms that there is a positive correlation.

This is a research report about the method of how to maintain qualification of certification flight test crews. KCA(Korea Certification Agency) have completed the KC-100 airplane certification flight tests which is the first time experienced flight tests operation. After the certification flight test, it has been found that annual flying time requirement of 100 hours to the certification flight test pilot is too strict, and other several requirements to maintain the qualification of the certification test crew such as aircraft certification introduction training, initial flight test pilot and flight test engineer certification training, crew resource management training, aviation physiology training, and survival training was difficult to implement in Korean civil aviation environments. In this study, it was suggested that 30 hours of flying time for maintaining certification flight test pilot qualification could be applied to contribute for safe operation of certification flight test and the other training requirements of the certification flight test crew could be fulfilled using self made training courses, existing FAA training courses and Korean Air Force training resources. Therefore, it is recommended that the regulation of maintaining the certification flight test crew qualification should be refined to implement the requirement practically.

A small wastewater collection system for rural area was reviewed and the small diameter gravity (SDG) was thought to be the most appropriate. The pilot-scale field experiment was performed for 15 months and the result is presented. The wastewater used for experiment was the effluent of septic tank in Kon-Kuk University, and components are similar to normal domestic wastewater. The SDG experimental system included 2" PVC pipe and reverse-sloped lower section is included. No clogging problem by solids was experienced at the points where flow direction changed. The pipe-breaking by freezing was experienced during the cold weather, thus proper protection may be required where severe weather is expected.
