In order to develop the computerized information system of occupational health management at worksite, we surveyed actual states of computer use at worksites. We used a self-administrative questionnaire to the members of Korean Association of Occupational Health Nursing(KAOHN) from July 4 to August 21 in 1997. Among the members of KAOHN, 147 members answered. The worksites where they were employed were very diverse in aspect of jobs, locations, and size. Occupational health computerized system was used at 30(20.4%) worksites among 147 respondants. When they first introduced the computerized system the most difficult problem was the lack of support of manager. The programs that they have used mainly consist of drug management, health examination management, disease management, but the program of worksite environment management have been rarely used. Most users felt that the computerized system was effective, but there were problems in connection within programs. Many worksites have plans to take or expand the computerized information system within several years. It is necessary to develop the effective and integrated occupational health computerized system.

Objective: Non-homologous end joining (NHEJ) is one of the pathways of repair of DNA double-strand breaks. A number of genes involved in NHEJ have been implicated as breast cancer susceptibility genes such as LIG4. However, some studies have generated conflicting results. The aim of this Human Genome Epidemiology (HuGE) review and meta-analysis was to investigate association between LIG4 gene polymorphisms in the NHEJ pathway and breast cancer risk. Methods: Studies focusing on the relationship between LIG4 gene polymorphisms and susceptibility to breast cancer were selected from the Pubmed, Cochrane library, Embase, Web of Science, Springerlink, CNKI and CBM databases. Data were extracted by two independent reviewers and the meta-analysis was performed with Review Manager Version 5.1.6 and STATA Version 12.0 software, calculating odds ratios (ORs) with 95% confidence intervals (95%CIs). Results: According to the inclusion criteria, we final included seven studies with a total of 10,321 breast cancer cases and 10,160 healthy controls in the meta-analysis. The results showed no association between LIG4 gene polymorphisms (rs1805386 T>C, rs1805389 C>T, rs1805388 C>T and rs2232641 A>G) and breast cancer risk, suggesting that the mutant situation of these SNPs neither increased nor decreased the risk for breast cancer. In the subgroup analysis by Hardy-Weinberg equilibrium (HWE) and ethnicity, we also found no associations between the variants of LIG4 gene and breast cancer risk among HWE, non-HWE, Caucasians, Asians and Africans. Conclusion: This meta-analysis suggests that there is a lack of any association between LIG4 gene polymorphisms and the risk of breast cancer.

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.

This study was conducted to identify the problems related to operation of the committee system in university hospitals and to propose the direction for reforming it. Data were collected by surveying 138 working-level administration managers of committees from 12 university hospitals in Seoul in October, 1995. The results were as follows: 1. The purposes of the committee were to promote the reasonable dicision making in the hospitals, to satisfy the requirement of Hospital Accreditation Program and, to execute the administrational instructions in due order. The sort of job which was charged of chairmen and the majority of committee member was doctor. 2. The committees which were to be held the meeting frequently in a year were general management committees(8.25 times/year). But in case of operation rate, medical care-related committees showed the most frequent meeting(90.15%). Most of committees made the regulations and reported the results of their meeting to the CEO of their hospitals by written documents. 3. Most doctors thought the medical care-related committees useful. Medical technicians regarded education and research-related committees as useful, while administrators favored the general management committees. 4. The factors related to the perceived performance of the committee were the kind of job, the class of job and the kind of committee. Also, the perceived performance of the committee was positively related to the usefulness in efficient management of work, and negatively to uncertainties in responsibility and a nominal role of the committee. 5. Most of the respondnts thought that the concern of the top manager about the committee was the most important factor for the improvement of committee system at hospitals. They also regarded that formalization of the objectives and regulation rule and composition of committees with members which work in various fields as essential. Further studies on the organizational and operational cjharacteristics which include general hospitals in various areas are required.

The names of medical technologist in Korea, Japan, and the United State of America vary depending on the medical system, educational system, and work areas. Conventionally, jobs equal or similar to medical technologist (commonly known as clinical laboratory technologist, medical laboratory technologist, clinical laboratory scientist, and medical laboratory scientist), histotechnologist, cytotechnologist, and genetic technologist. Jobs, such as extracorporeal technologist, medical electrophysiology technologist, and medical sonographer, allow other allied health professionals including medical technologists, to obtain their qualification. The work areas of medical technologists are classified into clinical pathologic technology, pathologic technology, clinical genetics technology, nuclear medicine in vitro technology, and clinical physiologic technology. New titles of Korean specialized medical technologists refer to certification systems, such as CLMJ, CMAJ, ASCP, IAC, ABRET, and ARMDS. Currently, there are eight types of specialized medical technologists under the cooperation of specialized academic societies. They are hematology, transfusionology, chemistry, immunology, microbiology, histology, cytology, nuclear medicine. It can be further divided into 20 categories according to the work areas such as mass spectrometry, infection control, Pathologists' Assistant, flow cytometry, HLA, cytogenetics, molecular genetics, cardiopulmonary physiology, neurophysiology (EEG/EMG/PSG/etc.), cardiac sonography, neurosonography (TCD/carotid), and medical device quality manager.

It is important how the leader leads the organizational members with leadership appropriate to environment changes as the leader has great influence on the management of hospital organization. These data were collected from the questionnaire surveyed, from February 14 through February 28, 2003, to 218 people among those in the field of doctorship, management administration, nursing, technology, medical engineering, management engineering, and general affairs, working for three hospitals under S medical foundation in Pusan. The principal findings of this research are as below : 1. Type of leadership and job satisfaction had positive correlation in terms of both transformational and transactional leadership, with former having more relation than the latter. 2. Type of leadership and organizational commitment had positive correlation in terms of intellectual stimulus and situational rewards, having little relation statistically. 3. Type of leadership and turnover intentions had negative correlation only in individual consideration, situational rewards, and exceptional management, showing that transactional leadership had more relation than transformational leadership. 4. In terms of leadership and its effect on the organizational performance and turnover intentions, transformational leadership had more correlation than transactional leadership. But transactional leadership also turned out to have effect on organizational performance. When transformational leadership used, turnover intentions were lower than when transactional leadership used. However, both transformational and transactional leadership had negative correlation to turnover intentions. 5. Effect that type of leadership according to job classification, status, age, and academic career has on organizational performance and turnover intentions was differed by those factors; especially, in the occupation of doctor, both transformational and transactional leadership had positive correlation to turnover intentions. 6. Regression analysis on the factors of organizational performance and turnover intentions showed that higher age had positive correlation to the organizational performance in terms of socio-demographical features and that the more leadership was used for charismatic and situational rewards and the less leadership was used for intellectual stimuli, the higher organizational performance was likely. In short, hospital operators and managers should examine each manager's qualification, type, and style of leadership in the hospital organization, and they must develop lasting programs for effective education and training for developing characteristics of leadership are in needed to have managers with appropriate managerial mind to respective post and status. It should be kept in mind that manager's leadership especially has great effect on members' goal-setting, goal-achievement, organizational performance, and turnover intentions as it is a decisive factor of organizational members' attitude and motivation.

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.

Objectives: The aim of the present study was to investigate the relationships among hospital safety climate, patient safety climate, and safety outcomes among nurses. Methods: In the current cross-sectional study, the occupational safety climate, patient safety climate, and safety performance of nurses were measured using several questionnaires. Structural equation modeling was applied to test the relationships among occupational safety climate, patient safety climate, and safety performance. Results: A total of 211 nurses participated in this study. Over half of them were female (57.0%). The age of the participants tended to be between 20 years and 30 years old (55.5%), and slightly more than half had less than 5 years of work experience (51.5%). The maximum and minimum scores of occupational safety climate dimensions were found for reporting of errors and cumulative fatigue, respectively. Among the dimensions of patient safety climate, non-punitive response to errors had the highest mean score, and manager expectations and actions promoting patient safety had the lowest mean score. The correlation coefficient for the relationship between occupational safety climate and patient safety climate was 0.63 (p<0.05). Occupational safety climate and patient safety climate also showed significant correlations with safety performance. Conclusions: Close correlations were found among occupational safety climate, patient safety climate, and nurses' safety performance. Therefore, improving both the occupational and patient safety climate can improve nurses' safety performance, consequently decreasing occupational and patient-related adverse outcomes in healthcare units.

Objectives : The purpose of this study was to survey the opinion and attitude of hospital managers toward the hospital evaluation program. Method : Managers of 157 hospitals which had participated in the hospital evaluation program were requested to respond to structured self-administered questionnaire. The questionnaire was composed with five categories: the preparation for the hospital evaluation program, the expertise levels of surveyors, the process and contents of the hospital evaluation program, the applying strategies for the result of the hospital evaluation to manager's work at their hospitals, and the main points to improve the hospital evaluation program. Result : 135 out of the 157 subjects completed the questionnaire, and the overall response rate was 86%. The hospital managers answered that they didn't have enough information such as the scoring rule of the standards, the process of the evaluation, and how to ask and get an answer to prepare the hospital evaluation. Furthermore, they estimated that the surveyors weren't specialized enough and didn't give a chance of checking over the result of the evaluation. In addition, they experienced that the result and feedback of the evaluation weren't enough information to be used as a guideline to improve in hospital management. Managers of the hospitals responded that the standards and method of survey in the hospital evaluation system should be reformed. Conclusion : Most of the responded managers seemed to have negative opinion on the hospital evaluation system, even though they were pushed up for interest in quality. Further studies and extensive evaluation of the hospital evaluation program are needed to bring up various information such as receptiveness and effectiveness.

This study aimed to identify needed improvements to current evaluation methods in medical school computer-based test (CBT) programs and test environments. To that end, an analysis of the importance and satisfaction was conducted through a survey of 3rd and 4th year medical students who had sufficient experience with CBT programs. Importance performance analysis methodology using the correlation coefficient was applied to assess average satisfaction and importance. The first quadrant (keep up the good work) was a factor of review and time management and test facilities among the conveniences of the CBT program. The second quadrant (concentrate here) was a factor of the convenience of the CBT program and computer monitor and chair factor within the test facilities. The third quadrant (low priority) was a factor of cheating and computer failure. The fourth quadrant (possible overkill) was the location, spacing, and temperature factors of the test facilities. Improvements are needed to reduce 'eye fatigue' and help students focus and understand the questions in the CBT programs. It is necessary to improve computer monitors, desks and chairs, and consider the subject's body type and manager in order to cope with computer breakdown and peripheral failures. Spare computers are needed. These findings are meaningful in that they have been able to identify factors that require improvement in the CBT program and test environment resulting from changes in assessment tools.
