In order to choose work system of fire organization between specialization system and multi- tasking system, fire organization's works should be analyzed. The most important thing of this task is evaluation of speciality of work that can be performed by estimating the duration of expertise of fire fighters' work. In this study I estimated the duration by survey. The duration is 12 years and 5 months which is a year and 9 months after promotion to fire senior sergeant lank in the case of average fire fighter.

Artists such as Duchamp and Balla tried to portray moving objects on static canvases by superimposing snapshots of moving objects. Previously, our group showed the influence of prior experience on brain responses within a motion-sensitive area MT+ to abstr act paintings with or without implied motion. In the present study, we went further to investigate whether the differential MT+activation between observers is originated from differential eye movement patterns. Prior experience was defined operationally with major in art. In addition, we examined whether perceiver's awareness of artist's intention concerning the implied motion, as well as expertise in art, affects the way he/she views the artwork. Results showed that the number and the duration of fixation on the abstract paintings tended to differ between participants based on art major. The awareness of artist's intention was not related to such differences. In contrast, observers' awareness of artist's intention of implying motion affected eye movement patterns in specific regions of the abstract paintings where the motion was portrayed. In other words, observers with awareness focused more on the parts of paintings portraying motion and moved their eyes in the direction corresponding to the direction of moving objects than observers without awareness. Expertise was not related to such specific eye movement patterns. The present study implies that art expertise and awareness of artist's intention play differential roles in observers' perception of paintings with implied motion. Namely, it suggests that expertise is related to the overall perception of paintings, while awareness of implied motion is related to perception of the specific spatial information in those paintings.

Objectives: Here, we present cases of mandibular fracture that were managed with the cortical lag screw fixation technique (CLSFT) in order to critically evaluate technique indications and limitations of application at various fracture sites. Materials and Methods: This was a retrospective cohort study. The study sample was composed of patients suffering from mandibular fractures that were treated by the CLSFT. The outcome variables were fracture type, duration of surgery, number of screws, and pattern of application. Other study categories included patient demographics and causes of injury. Chi-square tests were used to assess descriptive and inferential statistical differences, and the P-value was set at 0.05. Results: Thirty-three patients were included in the study sample, with a mean age of 30.9±11.5 years and a male predominance of 81.8%. The technique was applied more frequently in the anterior mandibular region (51.5%) than in other sites. Double CLSFT screws were required at the symphysis and parasymphysis, while single screws were used for body and angle regions. No intraoperative and postoperative variables were significantly different except for surgical duration, which was significantly different between the sites studied (P=0.035). Conclusion: We found that CLSFT is a rapid, cost-effective technique for the fixation of mandibular fractures yielding good treatment results and very limited complications. However, this technique is sensitive and requires surgical expertise to be applied to mandibular fractures that have specialized characteristics.

Purpose: This study aims to find the sources of nurses' conflicts and to find ways to eliminate them for improved nursing care. Method: This study is based on a phenomenological approach. All participants were woking at K-hospital, located in Seoul. The research was performed from September 2000 to February 2001. Data was collected through interviews and observations while participants were working. Interviews lasted a duration of one and half hours and data collection accured five to six times per participant. The data were analysed by Giorgi method and the results are as follows: Result: Essential themes in the professional conflict of clinical nurses emerged (1) The discords of human relationships ; (2) Dissatisfaction with working conditions ; (3) Lack of self-respect in one's professional expertise ; (4) Dissatisfaction with one's work ; (5) Depression accurring due to one's ability as a professional. Conclusion: The foregoing arguments suggest that nurses perform stressful environments in a hospital originating from the relationship among peer group, working conditions, and lack of self-respect as a nurses. Therefore, hospital authorities should strangly consider working conditions, interpersonal relationships, and working conditions in order to promote self-respect of the nurses hospitals.

The Medical Research Council has for some years encouraged collaborative clinical trials in leukaemia and other cancers, reporting the results in the medical literature. One unreported result which deserves such publication is the development of the expertise to design and analyse such trials. This report was prepared by a group of British and American statisticians, but it is intended for people without any statistical expertise. Part!, which appears in this issue, discusses the design of such trials; Part II, which will appear separately in the January 1977 issue of the Journal, gives full instructions for the statistical analysis of such trials by means of life tables and the logrank test, including a worked example, and discusses the interpretation of trial results, including brief reports of particular trials. Both parts of this report are relevant to all clinical trials which study time to death, and would be equally relevant to clinical trials which study time to other particular classes of untoward event: first stroke, perhaps, or first relapse, metastasis, disease recurrence, thrombosis, transplant rejection, or death from a particular cause. Part I, in this issue, collects together ideas that have mostly already appeared in the medical literature, but Part II, next month, is the first simple account yet published for non-statistical physicians of how to analyse efficiently data from clinical trials of survival duration. Such trials include the majority of all clinical trials of cancer therapy; in cancer trials, however, it may be preferable to use these statistical methods to study time to local recurrence of tumour, or to study time to detectable metastatic spread, in addition to studying total survival. Solid tumours can be staged at diagnosis; if this, or any other available information in some other disease is an important determinant of outcome, it can be used to make the overall logrank test for the whole heterogeneous trial population more sensitive, and more intuitively satisfactory, for it will then only be necessary to compare like with like, and not, by chance, Stage I with Stage III.

Incident management is significant far the traffic management systems. The management of incidents determines the smoothness of freeway operations. The dynamic nature of incidents and the uncertainty associated with them require solutions based on the incident operator's judgment. Fuzz systems attempt to adapt such human expertise and are designed to replicate the decision making capability of on operator. Fuzzy systems process complex traffic information, and transmit it in a simplified, understandable form to human traffic operators. In this study, fuzzy rules were developed based on data from real incidents on Santa Monica Freeway in LosAngeles. The fuzzy rules ail linguistic based, and hence, user-friendly. A comparison of the results from the linguistic model with the real incident durations indicate that the outputs from the model reliably correspond to real incident durations conditions. The model reliably predicts the freeway incident duration. The modes can thus be used as an effective management tool for freeway incident response systems. The approach could be applied to other problems regarding dispatch systems in transportation.

Knotworking represents a distributed collaborative expertise in pursuit of a task that is organized among designers from different design disciplines. Construction processes involve phases and tasks that cannot be solved in one organization only, as integration of expert knowledge from various sources is needed. Through knotworking, groups of people, tasks and tools are set to work intensively for a short period of time to solve a problem or accomplish a task. Knotworking requires intensive collaboration across organizational boundaries and hierarchies. The practice of knotworking has been developed and applied in the development of healthcare organizations, libraries and school-university relationships, but it has not previously been applied in the construction industry. In this paper, we describe the concept of knotworking and the findings of a case study that we completed in the Finnish construction industry. We will also compare the similarities and differences of the Big Room and knotworking in terms of participants, duration, target, space/infrastructure, benefits and challenges. Finally, we present some suggestions for further research and experimentation on knotworking in construction projects.

Context: Tobacco is the single largest cause of preventable death among adults globally, as it is in India. Despite this alarming situation, there is very minimal inclusion of tobacco in formal education systems, including the medical discipline, in India. Aims: The present study analyzed the extent of integration of tobacco control related content in Masters of Public Health (MPH) curricula of various institutes in India. Materials and Methods: This cross-sectional study was conducted during January 2011 to May 2011 in all colleges of the country offering a MPH course. The colleges were enlisted using various internet search engines (Google Scholar, Pubmed, Medline), other published literature and snowball technique. A 50 items semi-structured questionnaire was designed, posted and e-mailed (followed by hard copy) to the Person-In-Charge of the MPH program. Statistical Analysis: Descriptive statistics were used to profile the tobacco control content in respective institutions. All data entry and analysis was conducted using SPSS (version 16) for windows. Results: The duration of the MPH course was two years in all institutes and had accreditation with some affiliated body. Tobacco related diseases were covered under 'non communicable diseases' section by every institute. However, a mere 41.4% of institute's had faculty who had received specialized training in tobacco control. More coverage was given to health risks and effects of smoking as compared to cessation interventions (5 A's), symptoms of withdrawal and pharmacological treatments. Only 25% of institutes were in process of introducing tobacco courses into their curricula. Lack of expertise and administrative barriers were cited as perceived major problems in inclusion of tobacco control in MPH curricula. Conclusions: It can be concluded that tobacco control is not receiving adequate attention in public health curricula in India. There is a need for coordinated efforts in the area of tobacco control so as to reduce morbidity and mortality from tobacco induced diseases.

Purpose: This study was conducted in order to explore home visiting therapists' self-perceived role, problems, and supplement points of the home-based rehabilitation (HR) program based on the community-based rehabilitation (CBR) model. Methods: Four home visiting physical therapists, who conducted the HR program, participated in this study. After completion of the HR program, in-depth interviews were conducted using a semi-structured questionnaire for participants to explore their self-perceived role, problems, and supplement points of the HR program. Results: Participants regarded the role of the HR program as for "the linkage between recipient & society", "maintenance & improvement of recipients' physical function", and "education of recipient about the way of self rehabilitation". The problems and supplement points were derived from all phases of the HR program, including "human & material resources", "training program for human resources for HR service", "selection of recipient of HR service", "contents of the intervention for HR service", and "duration of HR service". Conclusion: These findings indicate that participants well recognized the intention of the HR program based on the CBR model, and suggest that high-quality human resources with rich expertise and experiences, a training program for HR service led by experts, and selection of recipients led by experts are necessary for an effective HR program. In addition, strategies and capacities specified to HR service should be identified, and applied to the training program for human resources for HR service. The results of this study could provide useful information when the government decides on the next guideline for home visiting health service.

Backgrounds/Aims: Laparoscopic cholecystectomy within one week of acute cholecystitis is considered safe and advantageous. Surgery beyond first week is reserved for non-resolving attack or complications. To compare clinical outcomes of patients undergoing laparoscopic cholecystectomy in the first week and between two to six weeks of an attack of acute cholecystitis. Methods: In an analysis of a prospectively maintained database, all patients who underwent laparoscopic cholecystectomy for acute cholecystitis were divided into two groups: group A, operated within one week; and group B, operated between two to six weeks of an attack. Main variables studied were mean operative time, conversion to open cholecystectomy, morbidity profile, and duration of hospital stay. Results: A total of 116 patients (74 in group A and 42 in group B) were included. Mean interval between onset of symptoms & surgery was five days (range, 1-7 days) in group A and 12 days (range, 8-20 days) in group B. Operative time and incidence of subtotal cholecystectomy were higher in group B (statistically not significant). Mean postoperative stay was 2 days in group A and 3 days in group B. Laparoscopy was converted to open cholecystectomy in two patients in each group. There was no incidence of biliary injury. One patient in group B died during the postoperative period due to continued sepsis and multiorgan failure. Conclusions: In tertiary care setting, with adequate surgical expertise, laparoscopic cholecystectomy can be safely performed in patients with acute cholecystitis irrespective of the time of presentation.
