There is an important concern regarding the First-line nurse manager's leadership because of the recognition that effectiveness of Leadership in this position results in benefits for the whole health care organization. So knowledge and practice of effective leadership behavior are now more essential to nursing than ever before. First-line Nurse Managers must be effective leaders to meet today's challenge because staff nurse, patient are affected by them. So the purpose of this study was to identify and to analyse the need for Leadership program of First-Line nurse managers in university hospitals. There were three major purposes of this study. First, identify First-line nurse managers general characteristic, second, identify their experience of leadership training, third, identify and analysis their demands for leadership training program. The subjects for this study was 167 First-line nurse manager randomly from 18 university hospitals in Korea. The data were collected through questionnaires from Oct. 13th to Nov. 20th, 1997, data was analysed using frequencies and percentages. Especially the steps of analysis of descriptions were as follows: Initial analysis centered on the identification of the demands of first-line nurse managers. Later analysis collapsed the demands into broad categories. From the collect data, 283 demands of first-line nurse managers were identified. These demands were then sorted into 3 broad categories that included : Self development as first-line nurse managers, relationship with others, and practice. The result of the study were as follows ; 1) Most of nurse managers(79.6%) had leadership training course and had good experience to improve self leadership. 2) Their demands of leadership training course are as follows First, for self as first-line nurse managers, they want to learn leadership theory, identify their leadership style and then develop their leadership skill. Second, for others as first-line nurse managers, they want to improve their communication skill, empowering others, relationship with others. Third, for patients as first-line nurse managers, improve their knowledge of practice. From the above finding, this study can be suggested the following; 1. Develope a leadership training course to improve first- line nurse manager's leadership skill according to their demands, so they will be better able to lead staff nurses for organization purposes. 2. When develope leadership training program, it must be contained the factors which first-line nurse managers want to learn.

Background: Platinum-hased chemotherapy for advanced non-small cell lung cancer (NSCLC) is still considered the first choice, presenting a modest survival advantage. However, the patients eventually experience disease progression and require second-line therapy. While there are reliable predictors to identify patients receiving first-line chemotherapy, very little knowledge is available about the prognostic factors in patients who receive second-line treatments. The present study was therefore performed. Methods: We retrospectively reviewed 107 patients receiving second-line treatments from August 2002 to March 2012 in the Dicle University, School of Medicine, Department of Medical Oncology. Fourteen potential prognostic variables were chosen for analysis in this study. Univariate and multivariate analyses were conducted to identify prognostic factors associated with survival. Result: The results of univariate analysis for overall survival (OS) were identified to have prognostic significance: performance status (PS), stage, response to first-line chemotherapy response to second-line chemotherapy and number of metastasis. PS, diabetes mellitus (DM), response to first-line chemotherapy and response to second-line chemotherapy were identified to have prognostic significance for progression-free survival (PFS). Multivariate analysis showed that PS, response to first-line chemotherapy and response to second-line chemotherapy were considered independent prognostic factors for OS. Furthermore, PS and response to second-line chemotherapy were considered independent prognostic factors for PFS. Conclusion: In conclusion, PS, response to first and second-line chemotherapy were identified as important prognostic factors for OS in advanced NSCLC patients who were undergoing second-line palliative treatment. Furthermore, PS and response to second-line chemotherapy were considered independent prognostic factors for PFS. It may be concluded that these findings may facilitate pretreatment prediction of survival and can be used for selecting patients for the correct choice of treatment.

In human societies, there are various organizations which are unique and have different roles. Among them, hospital organization are much more complex than other organizations because of their multitude of professional groups each with its own goals. To achieve its purposes, hospital should manage each professional group effectively. Hospital nursing organizations are the core positions in hospitals for patient care. Therefore nursing organizations have have efficient nurse managers to lead nurses for their own purposes. First- line nurse managers have special tasks for patients and nurses, which include to motivating, managing communicating with the people. So they should have high self-efficacy, which is the belief that one can successfully perform the behaviors in question. Self-Efficacy of first line nurse managers that asked them for leading their staff, and their tasks, is essential to bring about self-realization of staff nurses through motivation and job satisfaction, taking advantage of sound surrounding which is able to operate her staff nurses in order to function efficiently. But there were few studies on the topic in a hospital setting. This study was designed to measure first-line nurse managers' self-efficacy. The subjects for this Study were 167 first-line nurse managers randomly selected from 18 university hospitals in Korea. The Self-Efficacy was measured using 'The general self-efficacy scale' developed by Sherer and Maddux(1982). The data were collected through questionnaires and analysed using SAS program, frequencies, percentages and Pearson' correlation coefficients. The results of this study were as follows : 1. The average of first- line nurse managers' self- efficacy was 66.7. 2. The correlation between first-line nurse managers' self- efficacy and general characteristics(age, education, career) was not significant. From the above findings, this study can suggest the following : 1. Repeat studies are needed in various hospital settings. 2. First-line nurse managers must be trained with special programs for each nursing organizations' purposes.

The health care environment becomes more competitive every day. It has fallen to nurse managers - from vice presidents of patient care to nurse managers and their assistants - to recruit and develop a workforce that successfully meets the needs of both patients and the organization. This means employees who demonstrate advanced critical thinking skills, creative problem solving, and sound decision making skills combined with clinical skills and patient advocacy. The environment which nurse managers create and the way they relate to their workforce, are pivotal to organizational viability. Especially leadership of first -line nurse managers contributes to the success of their organizations. First-line nurse managers are deserved to be one of the most administrative supervisors through the middle stratum in a hospital organization as being a manager in the field service if assessed from the overall aspects of hospital, as being an interim managers in the nursing department as well as being a supreme supervisor in a unit in terms of an organizational structure in the hospital. Similarly, as a compete leader, the first-line nurse managers have not only a professional which is qualified to perform a role of appropriate coordination with medical staff and key personnel but also hold an important key position a being responsible for performing his or her given role. The first-line nurse manager is expected to manage human and fiscal resources in ways not required before. While an identified need for well-prepared first-line nurse manager continues to plague the profession, first-line nurse managers often have difficulty providing the leadership required. The need leadership training to function effectively in their positions. But we hardly find a useful leadership training program for first-line nurse managers, therefore the purpose of this study was to developed the leadership training program for them. The steps of leadership program development were below: 1st step, 2 studies were done before develop a leadership program. One was done to ask to first-line nurse managers what they want to learn through leadership training, the other one was to ask the staff nurses what their opinions are for their first-line nurse managers leadership. 2nd step was searching other leadership programs contents. The results of this study were below: The total amount of hours is 24. Leadership training program contents are : Future of nursing profession (210min), understanding basic factor's of leadership and leadership theories(310 min), self understanding as first- line nurse managers(320 min), basic principle and practice of interpersonal relationship(210 min), assertiveness training, conflict management (180min), and group study(210min). This is challenging time to be a leader, especially in nursing. As nurse managers look toward the new millennium, it seems as through the same struggles are ahead that are behind. So nurse managers need to embrace change with a positive attitude. They need to demonstrate risk taking and support it in their staffs. All these things are possible that after they participate the leadership training program.

The objective of this thesis to Provide a better insight into the effect of the amount of in-process storage has on the efficiency of production line with variable operation times. It is assumed that the material enters the line at the first work station and is then processed progressively through the line until it exits at the last work station, a finite amount of in-process storage is provided before all but the first work station of the line and the operation time of the work stations are statistically independent and follow exponential distribution. Under the above assumption, optimum allocation model is developed and following two approaches are used : 1) Given the available storage capacity, optimum allocation which minimizes the number of items in the line. 2) Given the available storage capacity, optimum allocation which. maximizes the utilization factor of the line. In a balanced three stage line, the production line efficiency is maximized under both categories when the second in-process storage is larger than the first.

Background: Chemotherapy is the mainstay of treatment for the majority of patients with advanced non-small cell lung cancer (NSCLC) without driver mutations and many receive therapies beyond first-line. Second-line chemotherapy has been disappointing both in terms of response rate and survival and we know relatively little about the prognostic factors. Materials and Methods: One thousand and eight patients with advanced NSCLC who received second-line chemotherapy after progression were reviewed in Shanghai Pulmonary Hospital, China, from September 2005 to July 2010. We analyzed the effects of potential prognostic factors on the outcomes of second-line chemotherapy (overall response rate, ORR; progression free survival, PFS; overall survival, OS). Results: The response and progression free survival of first-line chemotherapy affects the ORR, PFS and OS of second-line chemotherapy (ORR: CR/PR 15.4%, SD 10.1%, PD2.3%, p<0.001; PFS: CR/PR 3.80 months, SD 2.77 months, PD 2.03 months, p<0.001; OS: CR/PR 11.60 months, SD 10.33 months, PD 6.57 months, p=0.578, p<0.001, p<0.001, respectively). On multivariate analysis, better response to first-line therapy (CR/PR: HR=0.751, p=0.002; SD: HR=0.781, p=0.021) and progression within 3-6 months (HR=0.626, p<0.001), together with adenocarcinoma (HR=0.815, p=0.017), without liver metastasis (HR=0.541, p=0.001), never-smoker (HR=0.772, p=0.001), and ECOG PS 0-1 (HR=0.745, p=0.021) were predictors for good OS following second-line chemotherapy. Conclusions: Patients who responded to first-line chemotherapy had a better outcome after second-line therapy for advanced NSCLC, and the efficacy of first-line chemotherapy, period of progression, histology, liver metastasis, smoking status and ECOG PS were independent prognostic factors for OS.

Background: This systemic analysis was conducted to evaluate the efficacy and safety of pemetrexed based chemotherapy in treating patients with metastatic breast cancer as first or second line chemotherapy. Methods: Clinical studies evaluating the efficacy and safety of pemetrexed based regimens on response and safety for patients with breast cancer were identified using a predefined search strategy. Pooled response rate (RR) of treatment were calculated. Results: In first line pemetrexed based regimens, 10 clinical studies which including 513 patients with advanced breast cancer were considered eligible for inclusion. For second line pemetrexed based chemotherapy, 5 clinical studies which including 281 patients with advanced breast cancer were considered eligible. Systemic analysis suggested that, in all patients, pooled RR was 32.6% (167/513) in pemetrexed based first line regimens, and 13.9 % (39/281) in pemetrexed based second line regimens. Major adverse effects were neutropenia, leukopenia, fatigue, and anemia in pemetrexed based first line treatment; and lymphopenia, neutropenia, leukopenia, as well as anemia in second line chemotherapy. One treatment related death occurred with pemetrexed based second line treatment. Conclusion: This systemic analysis suggests that pemetrexed based first line regimens are associated with a reasonable response rate and acceptable toxicity, however with low response rate for treating patients with metastatic breast cancer when is used in the second line.

Cake resistance is influenced by floc size deposited on membrane surface. Enlarging floc size can reduce cake resistance. The small particles are enlarged by coagulation and flocculation process in conventional mixing tank at membrane filtration system. Fully-grown flocs for reducing the cake resistance, however, are ruptured while passing through a pump. In light of this fact, this study aims to experimentally look at the reaggregation phenomenon of mixing system. In addition, reaggregation phenomenon of mixing system is compared with first-aggregation of in-line injection system in which coagulant is injected just before a pump. These results suggest that first-aggregation of in-line injection system is better than reaggregation of mixing system for G-value above $3100sec^{-1}$. Since G-value in pipe of actual membrane filtration system are usually larger than $3100sec^{-1}$. The performance of in-line injection system is expected to be better than the conventional mixing tank system.

The imprecise computation technique ensures that all time-critical tasks produce their results before their deadlines by trading off the quality of the results for the computation time requirements of the tasks. In the imprecise computation, most scheduling problems of satisfying both 0/1 constraints and timing constraints, while the total error is minimized, are NP-complete when the optional tasks have arbitrary processing times. In the previous studies, the reasonable strategies of scheduling tasks with the 0/1 constraints on uniprocessors and multiprocessors for minimizing the total error are proposed. But, these algorithms are all off-line algorithms. Then, in the on-line scheduling, NORA(No Off-line tasks and on-line tasks Ready upon Arrival) algorithm can find a schedule with the minimum total error. In NORA algorithm, EDF(Earliest Deadline First) strategy is adopted in the scheduling of optional tasks. On the other hand, for the task system with 0/1 constraints, NORA algorithm may not suitable any more for minimizing total error of the imprecise tasks. Therefore, in this paper, an on-line algorithm is proposed to minimize total error for the imprecise real-time task system with 0/1 constraints. This algorithm is suitable for the imprecise on-line system with 0/1 constraints. Next, to evaluate performance of this algorithm, a series of experiments are done. As a consequence of the performance comparison, it has been concluded that IOSMTE(Imprecise On-line Scheduling to Minimize Total Error) algorithm proposed in this paper outperforms LOF(Longest Optional First) strategy and SOF(Shortest Optional First) strategy for the most cases.
