Background: The LigaSure vessel sealing system has been proposed to save operation time and reduce intraoperative blood loss for various surgeries. However, its usage for gastric cancer is still controversial. The aim of the present meta-analysis was to compare the effectiveness of LigaSure with conventional surgery in gastrectomy. Materials and Methods: Sources were retrieved from the Cochrane Library, MEDLINE, EMBASE, SCOPUS and Google Scholar until February, 2015. All randomized controlled trials comparing LigaSure with conventional surgery in curative gastric cancer resection were selected. After data extraction, statistics were performed by Review Manager 5.1 software. Results: Three eligible randomized controlled trials were evaluated, with a total of 335 patients. The quality of the included trials was good, yet some methodological and clinical heterogeneity existed. There were no significant differences between the LigaSure and conventional groups in operative time (weighted mean difference [WMD], -22.95 minutes; 95% confidence interval [CI], [-59.75, 13.85]; P = 0.22), blood loss (WMD, -45.8 ml; 95% CI, [-134.5, 42.90]; P = 0.31), nor the incidence of surgical complications (odds ratio, 1.18; 95% CI, [0.68, 2.05]; P = 0.54). But there was a longer duration of hospital stay in LigaSure group (WMD, 1.41 days; 95% CI, [0.14, 2.68]; P = 0.03). Conclusions: All available randomized evidence has been summarized. LigaSure does not confer significant advantage over conventional surgery for curative gastric cancer resection. The usefulness of the device may be limited in gastrectomy. But, more trials are needed for further assessment of the LigaSure system for gastric cancer.

Backgrounds/Aims: Prehabilitation aims for preoperative optimisation to reduce postoperative complications. However, there is a paucity of data on its use in patients undergoing pancreaticoduodenectomy (PD). Thus, this study aims to evaluate the outcomes of a home-based outpatient prehabilitation program (PP) versus no-PP in patients undergoing PD. Methods: This retrospective cohort study compared patients who underwent PP versus no-PP before elective PD from January 2016 to December 2020. Inclusion criteria for PP were < 65 years or 65-74 years with FRAIL score < 3. No-PP included dietician, case manager and anesthesia review. PP included additional physiotherapy sessions, caregiver training and interim phone consultation. Univariate and multivariate analysis were used to evaluate length of stay (LOS), morbidity, 30-day readmission, and 90-day mortality. Results: Seventy-one patients (PP: n = 50 [70.4%]; no-PP: n = 21 [29.6%]) were included in this study. Median age was 65 years (interquartile range [IQR]: 58-72 years). Majority (n = 58 [81.7%]) of patients underwent open surgery. Ductal adenocarcinoma was the most common histology (49.3%). Patient demographics were comparable between both groups. Overall median LOS was 11.0 days (IQR: 8.0-17.0 days). Compared to no-PP, PP was not independently associated with reduced intra-abdominal collections (odds ratio [OR]: 0.43; 95% confidence interval [CI]: 0.03-6.11, p = 0.532), major morbidity (OR: 1.31; 95% CI: 0.09-19.47; p = 0.845) or 30-day readmission (OR: 3.16; 95% CI: 0.26-38.27; p = 0.365). There was one (1.4%) 30-day mortality. Conclusions: Our outpatient PP with unsupervised exercise regimes did not improve postoperative outcomes following elective PD.

The study has its purpose on providing basic resource to enforce the capability of the middle managers by examining the level of performance and the level of awareness about the capabilities of the managers and by understanding the significance of the difference and the reasons for the differences. The source of the study was 195 survey questionnaires that were carried out to the managers of the 9 general hospitals and the method of the analysis was the frequency analysis, analysis of the credibility, matching to sample T-test, independent sample T-test, dispersion analysis, correlation analysis, and multiple linear regression analysis using accumulated variables. The followings are the main result of the study. First, the difference between the level of awareness about the capabilities and the level of performance of the mediator managers in general hospitals had high capability in change management. The following orders were: competence in achievement and behavior, competence in management, competence in recognition, competence in influence, competence in individual effectiveness, and competence in personal relationship service. Second, as the result of the relation analysis in order to understand the correlation between awareness and performance of the mediator managers, everything had significant positive correlation. In the study about the level of importance, the cognitive capability and the management capability had the highest correlation with the correlation number of 0.88. In the study about the level of performance, the cognitive capability, individual capability, and the management capability had the highest correlation with the correlation variable number of 0.79. Third, as the result of studying the reason for the difference between the level of the awareness capability and the level of the performance, lack of the support recognition compensation in the organization level, inappropriate work environment, limit in the regulation were found as the highest reason in the order. As the result of the study, it was concluded that the creation of the efficient capability estimation model and the securement of the system that estimate the capability of the managers should be carried out in order to enforce the capability of the mediator managers in general hospitals.

원격 모니터링 시스템이란 네트웍에 분산된 호스트 혹은 원격 어플리케이션의 상태를 실시간으로 모니터링 하는 시스템이다. 네트웍에 분산된 호스트들은 다양한 플랫폼을 갖추고 있는 것이 현실이다. 하지만, 기존의 모니터링 시스템들은 플랫폼에 의존적인 성격을 띠고 있다. 네트웍을 통해서 모니터링을 하기 때문에 잠재적인 네트웍의 문제발생에 대한 적절한 대응이 필요하지만, 기존의 모니터링 시스템들은 네트웍의 문제에 대해서 적절하게 대응을 못하고 있다. 그리고 호스트의 상태를 변화시키는 요인은 호스트의 시스템 자원보다는 어플리케이션의 상태변화가 주 요인이 되고 있지만, 기존의 시스템들은 주로 호스트의 상태정보만 모니터링을 하고 있다. 따라서, 분산된 호스트들의 플랫폼에 독립적이고, 네트웍의 잠재적인 문제발생을 적절하게 대응을 할 수 있고, 호스트의 상태정보 보다는 호스트의 어플리케이션의 상태정보를 모니터링 하는 시스템이 필요한 실정이다. 본 논문에서는 네트웍에 분산된 어플리케이션의 실시간 모니터링을 통해서 어플리케이션 상태를 효과적으로 관리할 수 있는 모니터링 시스템인 RAMS (Remote Applications Monitoring System)의 설계 및 구현을 제시한다. 이 시스템은 네트웍에 분산된 호스트들의 효과적인 관리를 위해 호스트 어플리케이션의 상태를 모니터링 한다. RAMS는 모니터링 대상인 호스트 어플리케이션의 모니터링을 담당하는 Agent, 호스트의 등록, 관리를 담당하는 Manager로 구성된다. Manager와 Agent는 네트웍 단절 혹은 호스트 failure의 상황에도 자동으로 복구가 가능할 수 있도록 JINI를 최대한 활용함으로써 다른 시스템에 비해 시스템의 구성 및 관리가 용이한 특성을 갖는다.

Purpose: The aim of this study was to examine effects of patient safety culture and burnout on safety management activities with a focus on clinical experience of nurses in general hospitals. Methods: Self-administered questionnaires were given to nurses in a general hospital in C Province, and 107 questionnaires were used for final analysis. Collected data were analyzed using SPSS/WIN 21.0 Program for t-test, ANOVA, Pearson correlation coefficients, and multiple regression. Results: The highest score as perceived by general hospital nurses for patient safety culture was for 'Immediate superior/Manager' (3.84), for burnout, the highest score was for 'Emotional exhaustion' (4.13), and for safety management activities, the highest score was for 'Prevention of infection' (3.96). Patient safety culture and safety management activities perceived by general hospital nurses showed significant positive correlations (r=.35 p<.001). The correlations between burnout and safety management activities perceived by the nurses showed significant negative correlations (r=-.37, p<.001). Results of hierarchical regression analysis conducted to identify factors that affect safety management activities showed that patient safety culture (${\beta}=.40$ p<.001) was effective for controlling safety management activities. Conclusion: The findings indicate a need to build a patient safety culture that fits the characteristics and situations of various hospitals.

The purpose of this study was to provide basic materials needed to enhance quality of organizational life by identifying the improvements of labor union management in the perspective of general hospital organization management. The subject of this study were 686 employees in 12 General Hospitals in Metro Capital including Seoul. Materials were collected from administrators, nurses and medical technicians in target hospitals from March 20 to May 10, 2005 through survey questionnaires. The main results of this study were as follows: 1. the commitment level of the subjects according to their characteristics was higher in older employees than the younger ones, large family to support than small family to support and those who had higher positions in labor union. 2. The commitment level of the subjects according to the job and role related variables were higher those who had higher satisfaction level to their job and manager, role conflict in all hospitals. 3. The commitment level of the subjects according to union related variables, variables jointly controlled by union and employer was satistically significant positive correlation. In other words, the commitment level of the subjects according to the subjects' labor union involvement was higher in those who had higher satisfaction in labor union and perceived their colleagues' attitudes more positively in all hospitals. Regarding the atmosphere of the relationship between union and employer and the level of commitment in labor union, the better the atmosphere of the relationship between union and employer was, the higher the level of commitment in labor union was in all hospitals. 4. The results of multiple regression analysis shows that formal and informal socialization, union participation to the union management cooperation program, job satisfaction, satisfaction with the labor union's were all found as important antecedents of labor union commitment. 5. Job and role-related variables, union-related variables, variables jointly controlled by union and employer, and labor union commitment level were all found significantly different in accordance with the characteristics of unions concerned. To summarize study results, the level of commitment in labor union depends on job satisfaction, manager's attitudes, satisfaction to their jobs, union satisfaction, their colleagues attitudes toward union and the atmosphere of employer-employee relationship. Therefore hospital managers should have democratic and flexible attitudes toward labor union. Additionally, as formal and informal socialization, union participation to the union-management cooperation program is important determinant in union commitment, hospital managers should have countermeasures to enhance the colleague attitude and job satisfaction level of hospital employees. Since this study deals with psychological nature of workers not a few drawbacks and shortcomings may be detected in the finding. Nevertheless, the finding of this study, to become a momentum that will stimulate further research to detect all the cues of labor union commitment and to provide valuable reference in forming logical union commitment and labor union-management cooperation.

Background : It is increasing the concern for patient satisfaction as a customer information. This study was planned to investigate the activities related to patient satisfaction survey at the Korean hospitals. Methods : We performed the nationwide survey on 235 general hospitals by using the self-administrated checklist from Sep. 9 to Oct. 9, 1996. The response rate were 50.2%. We analyzed the descriptive statistics and chi-square test by SAS software on 118 hospitals. Results : First of all, 62.7% of study hospitals showed to conduct the patient satisfaction survey, and most of hospitals which did not conduct it had a plan to do it within 5 years. The reason that hospitals did not conduct satisfaction survey was due to a lack of administrator's interest or adequate questionnaire form. Second, the bigger, public and being more located in the big city or opened more than 10 years, the more hospitals conducted the patient satisfaction survey. Also, patient satisfaction survey was mainly handled by planning dept. or administrative team. Third, most hospitals had their own way of making questionnaires without proving reliability and validity. The results of the survey were applied to hospital management timely, and were mostly reported to top manager level. Most CEO concerned about the results of satisfaction survey. Fourth, the staffs in charge of survey had problems such as skill related to data analysis and development of questionnaire and they suggested that this problems could be solved through inducing the implementation of the survey results on hospital management, support for the development of standardized questionnaires and increasing the top manager's interests. Fifth, most questionnaires composed of lots of questioning items on hospital equipments and environment, and kindness of hospital employee to patients. Conclusions : Although this study had some limitations in generalization due to low response rate in big hospitals, it is meaningful to find the present state and the problems related to patient satisfaction survey of the general hospitals. We can conclude that there are increasing the concern for patient satisfaction survey among the hospitals nationwide, and it can be needed for technical support related to development of survey tool or method.
