According to many studies, a large number of police officers who had recently been exposed to an emergency situation has serious psychological stress and Post Traumatic Stress Disorder(PTSD) symptoms impact on morale, absenteeism, occupational health, early retirement, family relationships. However, in Korea as it looked during the empirical study of police officers with PTSD had a few. In this study, levels of PTSD among police officers to identify and respond accordingly was to seek ways. The officer's PTSD levels vary according to the study is the relatively high level, when compared to firefighters is a relatively high level. So, I suggested some countermeasures. I presented discovery and management of high risk police officers, distribution of critical incident stress management, introduction of employee assistance programs, active intervention of colleagues and family members, training of stress management techniques.

The purpose of this study is to derive the suggestion of satisfaction of e-book services on the basis of the recent literature on quality assessment for e-service which have been mainly studied on library realm. For this purpose, This study added post-management service which is applicable to measure satisfaction of e-book services based on E-S-Qual and Libqual. We expand our scope of service to using of e-book content and services for individual customers, and analyzed the relationship between satisfaction with the system, the content, the after-sale service. On this foundation, existing e-book service companies can offer their services more efficiently, thereby making the e-book content more diverse, along with developing specialized e-book service to increasing their customer's satisfaction. In addition, the latest and diversity is important as well. Moreover, performing rapid post-management services after the sale of the product or service, can be important variables for customer satisfaction. Therefore, not only the system and content, providing required level post-management services by customers can satisfy the existing customers and create new customers.

An American ginseng(Panax quillquefolium L) industry has emerged in British Columbia, Canada over the past ten years. Interest has grown very rapidly and with this development, attention is now moving away from field production issues and emphasis is being directed to enhancements in ginseng storage, drying and processing. There is a dearth of knowledge on these aspects even though they are crucial to international competitiveness. Enhancement dicatates the application of a systems approach to optimizing the harvest and post - harvest production system(crop digging, pre - washing cold storage. washing, drying and post - drying storage). Research in British Columbia to date has focussed on drying and storage issues and has resulted in the design of an enhanced commercial drying system. The role of dryer management, loading rates, airflow rates and pre - drying cold storage on American ginseng root drying rates and root quality were examined. From the dryer management experiments, there are distinct advantages to size sorting root to yield optimum drying rates. If unsorted root is used, efficiency is increased if the trays are systematically rotated. Loading rate experiments illustrate that increasing rates above those currently used in commercial dryers are possible without any sacrifice in quality. This has significant implications for commercial drying. Pre - drying cold storage is a most significant tool for managing drying operations. Over a period of six weeks, no discernable decrease in quality was found as a consequence of cold storage. Further, the moisture loss and the associated root surface changes(loss of surface soil in storage for example) provide new challenges for root quality management. Continued research and technological innovation will be crucial in addressing the demanding challenges of the future.

Objective: Condylar resorption (CR) is one of the major post-surgical complications of orthognathic surgery. This systematic review (SR) aimed to evaluate epidemiological data, risk factors, and therapeutical management of CR. Methods: Six databases were screened by two investigators until September 2020 to obtain all SRs. After reading the titles and abstracts, eligible SRs were determined and data extraction was performed. Using the latest version of A Measurement Tool to Assess Systematic Reviews, the methodological quality of the included SRs was determined. Results: Ten SRs with low or critically-low methodological quality were included in this review. Mandibular hypoplasia on the sagittal plane and hyperdivergent growth pattern on the vertical plane were the most common skeletal alterations in which CR could occur after orthognathic surgery. Post-operative condylar changes were analyzed both on two-dimensional and three-dimensional (3D) radiographic examinations. The incidence of CR was not related to the fixation method. Based on the severity of the pathological conditions, management of CR can include conservative or surgical therapy. Conclusions: Despite the limited evidence in literature, CR is considered a consequence of orthognathic surgery. However, an accurate diagnosis of CR and a better orthognathic surgical planning must include 3D radiographic examinations to improve pre- and post-surgical comparison. Well-designed studies with long-term follow-up and 3D data are needed to clarify the findings of this analysis..

The purpose of this study was to investigate the effects of mineral taping containing natural minerals powder on knee joint pain and swelling in the elderly. Forty elderly people with knee pain were divided into 20 mineral taping groups and 20 kinesio taping groups and randomly placed in a single blind manner. The study period was conducted from April 6, 2020 to April 7, 2020, and pain and blood flow by time point were examined before, after, and after 1 day of taping. Knee pain was significantly different in the post-test (F = 93.758, p <.001) and the post-day test (F = 93.758, p <0.001) for each measurement point. The blood flow test for edema was significantly different in the post-test (F = 48.648, p <0.001) and the post-day test (F = 35,427, p <0.001) for each measurement time point. There was no significant difference in the effect test result for each group (F = 0.160, p> 0.05). However, When comparing the retention effect after 1 day, the mineral taping group was excellent to the post-score than the Kinesio taping group. In the future, we believe that increasing the taping time and retention period will have a positive effect. It is thought that the results of this study will contribute to the study of taping materials in the future.

The Film-making industry in Korea has significantly expanded during last decade. However, the development didn't necessarily mean there's improvement in terms of the quality of life for the film staffs. In post-production stages, especially, any workers involved in the production can get tremendous amount of mental pressure and stress due to the deadline. Thus, in this period, most labor issues are found and often ignored. In this research, compared to Hollywood, Korean domestic film industry will be analyzed with focus on labor organizations. Their role will be explored and examined in terms of improving the qualify of life as well as of the film itself.

As education environment is changing rapidly and competition of education industry is more intensive, the importance of service view about education is increasing as a differential competitive advantage. This study attempted to investigate the impact of service convenience as a different competitive advantage on e-learning acceptance by using TAM. The purpose of this study is to examine how five-dimensional service convenience constructs(decision convenience, access convenience, transaction convenience, benefit convenience, post-benefit convenience) affect consumers' perceived usefulness, attitude and usage intention. For this study, data were gathered from respondents who bought or used e-learning services and analyzed by structural equation model. Among the five-dimensional service convenience constructs, two constructs(benefit convenience, post-benefit convenience) affected consumers' positive perceived usefulness, attitude and usage intention about e-learning service. The results show that management and investment to improve benefit and post-benefit service convenience make consumers' positive attitude and usage intention about e-learning service.

Alimentary tract duplication cysts are rare congenital anomalies, most commonly located in the ileum, but may present anywhere from mouth to anus.Clinically, they may be asymptomatic, incidentally diagnosed or may present with obstruction, volvulus, intussusception or gastrointestinal bleed. Here we report a case of a one year old male child presenting in gasping state and shock. Despite the initial strong suspicion of Meckel's diverticulum and tubercular abdomen, the final diagnosis remained elusive till exploratory laparotomy was performed which revealed a duplication cyst of ileum with perforation into the umbilicus. Duplication cyst should always be kept as a differential diagnosis so that early intervention can help in better management.
