Purpose: To evaluate association of giant cell tumors recurrence between markers of proliferation cells (MCM3, Ki-67 and HH3) Materials and Methods: Ten case of giant cell tumor of bone were reviewed. The patients were six males and four females (mean age: 33 yrs). All patients were done operation after biopsy. The radiologic grading was determined according to Enneking grading system. The immunohistochemical stains of MCM3, HH3, and Ki-67 were done with Microarray block. Results: The three cases of 10 cases (30%) were recurred at same sites. Two case of recurrence was grade II according to radiologic features. The remaining case was grade I. The expression rate of immunohistochemical markers in radiologic grade 2 and 3 were more increased than grade 1. But there was not association between radiologic grading and proliferation of tumor cells because result data was not coherence. Mean MCM3 labeling index of non-recurred case was 11.2%, recurred case was 7.2%. Ki-67 was 12% vs. 8.9%, respectively and HH3 was 66.9 % vs. 75.4%, respectively. Thus there was no association between local recurrence and immunohistochemical Ki-67, MCM3 expression rate. But HH3 marker expression rate was increased in recurred cases compared to non-recurred cases. Conclusion: Our study suggests that HH3 immunohistochemical marker can be a useful prognostic factor.

Purpose: This study aimed to explore the knowledge and performance of sleep hygiene among nurses with shift work schedules and examine the influence on sleep disturbance. Methods: A total of 199 shift-work nurses from a tertiary hospital were included in the study. To examine the knowledge and performance of sleep hygiene, the participants were asked to respond to a self-reported survey. To assess sleep disturbance, the General Sleep Disturbance Scale was used. Descriptive statistics and multiple linear regression were applied using the SPSS/WIN 21.0 program to analyze the data. Results: Both the knowledge and performance of sleep hygiene among nurses with shift work schedules were measured at a moderate level. Nurses' knowledge and the performance of sleep hygiene was not significantly associated with sleep disturbance, whereas age, experience with shift-working, and perceived health status were significantly associated. Conclusion: Strategies for providing more accurate information and motivating better sleep hygiene would help to enhance sleep hygiene in nurses with shift work schedules. Further studies examining the association of knowledge and the performance of sleep hygiene with sleep disturbances in nurses with shift work schedules are needed.

Acute appendicitis is one of the most common diseases of young people that requires emergency operation. This is especially true for those age 10 years old and older. However, the numbers of cases of appendicitis are increasing in both the young and the elderly. The main purpose of this study is to understand the clinical features of acute appendicitis in children and elderly patients. We retrospectively compared clinical characteristics in 4 groups of patients who underwent appendectomy in our hospital. There were 16 patients in the pre-school age group, 9 were males and 7 females. The total number of patients in the juvenile group were 287, 156 were males and 131 females. The total numbers of patients in the adult group were 794, 436 were males and 358 females. The numbers of elderly patients were 189, 91 were males and 98 females. Complicated appendicitis was found in 15 patients (93.7 %) in the pre-school age group, 79 patients (27.5 %) in the juvenile group, 332 patients (41.8 %) in the adult group, and 96 patients (50.7 %) in the elderly group. Four patients (40 %) had generalized panperitonitis in the pre-school group. The occurrence of perforated appendicitis was the highest in the pre-school age group and the lowest in the juvenile group. Since generalized panperitonitis has a higher incidence in the pre-school age group, prudent and careful diagnosis and treatment are required for the pre-school age group.

Purpose: To observe the effectiveness of the practical instruction sheet and the educational video for left-sided breast treatment in a patient receiving deep inspiration breath hold (DIBH) technique. Two parameters, simulation time and patient satisfaction, were assessed through the questionnaire. Methods: Two different approaches, which were the instruction sheet and educational video, were combinedly used to assist patients during DIBH procedures. The guideline was assigned at least 1 week before the simulation date. On the simulation day, patients would fill the questionnaire regarding their satisfaction with the DIBH instruction. The questionnaire was categorized into five levels: extremely satisfied to dissatisfied, sequentially. The patients were divided into four groups: not DIBH technique, DIBH without instruction materials, the DIBH with instruction sheet or educational video, and DIBH with both of instruction sheet and educational video. Results: Total number of 112 cases of left-sided breast cancer were analyzed. The simulation time during DIBH procedure significantly reduced when patients followed the instruction. There was no significant difference in simulation time on the DIBH procedures between patient compliance via instruction sheet or educational video or even following both of them. The excellent level was found at 4.6 ± 0.1 and 4.5 ± 0.1, for patients coaching via instruction sheet as well as on the educational video, respectively. Conclusion: Patient coaching before simulation could potentially reduce the lengthy time in the simulation process for DIBH technique. Practicing the DIBH technique before treatment is strongly advised.

In recent years, many of medical institution have reinforced educations for their employees aiming to secure competitiveness and to achieve higher performances. In an effort to actively response to the fast changing environment in the medical industry, the Ministry of Health and Welfare has implemented "Innovation and Service promotion" educations for employees of 34 regional medical institutions and 6 Red Cross hospitals. In this regards, the effect of the educations to change employees' mind for innovation and services and its results need to be evaluated. This study conducted surveys asking participants of the 2006 Education for Innovation of Regional Public Hospital Employees and Service Promotion and synthetically analyzes the effect of the education on their mind for services compare to their mind before the education. As a result, more them 92% of participants say that they are satisfied with the education, and many more participants agreed the effect of the education to change their mind for services. Under this circumstance, after the educations participants change more positively on "their mind for innovative services" and "their service skills in practice".

The main objective of this paper is to investigate the burnout state, coping types, and their relationship with organizational citizenship behavior, and based on the investigation, to provide some reference materials for effective management of burnout and appropriate methods of coping. For this purpose, employees of Korean Red Cross Blood Center were selected as the subject of the research. Data for empirical analysis were obtained through mail survey using structured and self-administered questionnaire for 282 employees of five Red Cross Blood Centers across the nation. Following is the summary of the results: 1) Degree of organizational citizenship behavior was higher among the married, the forties in age, and the employees whose major reason for choosing to work at the Center was 'to help other people.' On the other hand, degree of burnout was higher among the single but lower among the forties in age and the employees who chose to work at the Center because of suitable abilities and interests. As for the types of coping, problem-oriented coping method was more frequently used by the married, older, relatively more-educated and higher-grade employees. 2) Among the three kinds of burnout, 'achievement burnout' was found to have the greatest influence on the organizational citizenship behavior, negatively affecting organizational citizenship behavior as a whole and all of its components except for 'sportsmanship.' Next was 'impersonality burnout,' which also had negative effect on organizational citizenship behavior as a whole, and altruism, conscientiousness and sportsmanship among the components. Finally, 'emotion burnout' appeared to have positive effect on altruism and courtesy but negative effect on sportsmanship. 3) Among the various types of coping, 'problem-oriented' and 'positive perspective' coping methods were found to positively influence overall organizational citizenship behavior, whereas 'stress dissolution' had negative effect. These results imply that special management, counselling and education are needed for sociodemographic groups with high burnout to utilize problem-oriented and positive perspective coping methods which are considered to have desirable effects in coping with burnout problems. In addition, some methods should be devised to prevent and manage the 'achievement burnout' that was found to have great negative influence on organizational citizenship behavior.

Laparoscopic gastrectomy has become widely used as a minimally invasive technique for the treatment of gastric cancer. When it was first introduced, most surgeons preferred a laparoscopic-assisted approach with a minilaparotomy rather than a totally laparoscopic procedure because of the technical challenges of achieving an intracorporeal anastomosis. Recently, with improved skills and instruments, several surgeons have reported the safety and feasibility of a totally laparoscopic gastrectomy with intracorporeal anastomosis. This review describes the recent technical advances in intracorporeal anastomoses using circular and linear staplers that allow for totally laparoscopic distal, total, and proximal gastrectomies. Data that demonstrate advantages in early surgical outcomes of a total laparoscopic method compared to laparoscopic-assisted operations are also discussed.

This paper analyzes the technical efficiency of thirty two hospitals in Korea using DEA(Data Envelopment Analysis). DEA provides an efficiency measure for each hospital compared to the most efficient one. The amount and sources of inefficiency that are identified by the DEA are useful for benchmarking to improve efficiency. The results from multiple regression analysis and Wilcoxon Rank Sum test show that bed turnover, hospital size, and average length of stay are related to hospital efficiency.
