이 논문에서는 모바일 기기상에서 카메라기반 악보인식을 위한 오선 두께와 오선 간격을 추정하는 전처리 기술을 제안한다. 캡쳐된 영상은 조명이나, 흐려짐, 저해상도 등의 많은 왜곡으로 인해 인식에 어려움이 있다. 특히 복잡한 배경을 가지고 있는 악보 영상인식의 경우 더욱 그렇다. 악보 기호 인식에서 오선 두께와 오선 간격은 인식에 큰 영향을 끼친다. 이들 정보는 이진화에도 사용되는데, 복잡한 배경을 가지고 있는 경우 일반적인 이진 영상은 오선 두께와 간격을 추정하는데 만족스럽지 못하다. 따라서 우리는 에지영상에서 런-길이 엔코딩 기술을 이용해 오선 두께와 간격 추정하는 강건한 알고리즘을 제안한다. 제안된 방법은 2단계로 구성되어 있다. 첫 번째 단계는 소벨 연산자에 의해 영역별로 에지 영상을 기반으로 오선 두께와 간격을 추정한다. 각 에지 영상의 열은 런-길이 엔코딩 알고리즘에 의해 기술된다. 두 번째 단계는 안정한 경로 알고리즘을 이용한 오선 검출과 오선 위치를 추적하는 적응적 LTH알고리즘을 이용한 오선 제거이다. 실험결과 복잡한 영상의 경우에도 강건함과 높은 인식률을 보였다.

With the development of computer music notation programs, when drawing sheet music, it is often drawn using a computer. However, there are still many use of hand-written notations for educational purposes or to quickly draw sheet music such as listening and dictating. In previous studies, OMR focused on recognizing the printed music sheet made by music notation program. the result of handwritten OMR with camera is poor because different people have different writing methods, and lens distortion. In this study, as a pre-processing process for recognizing handwritten music sheet, we propose a method for recognizing a staff using linear regression and a method for recognizing a bar using CNN. F₁ scores of staff recognition and barline detection are 99.09% and 95.48%, respectively. This methodologies are expected to contribute to improving the accuracy of handwriting.

This study is aimed at examination and analysis of current status of university library's line and staff organization especially the private university's. Motivation for this study is based on the following facts : First, the library work now is changing from the conventional one to automated one. Second, librarians in the front line must be trained in the newly set work because of the separation of work process in automated libraries. Methodologies of this study, apart from theoretical aspects, were visiting and interviewing librarians at 30 university libraries, examining the current status and problems of the line and staff organization of the university libraries. The result from the study is as follows: First, interviewing reveals that 35% of the 75 private university library is having 'associate directorship by librarian' system. Benefits from this system are described, recommending other University libraries adopt this system. This system su n.0, pplements the weak point of concurrent director's office of lay professor, as well as encourages librarian's morale by promotion. Second, the current organization of the university libraries are to be reformed. Namely, 1) the name of each division must be newly and a n.0, ppropriately set of changed suiting for the work of automated library, thus reforming the division. This must be conducted via collection of opinions of the Korean Library and Information Science Society' and associated organizations. 2) Newly formed division(for example, administrative division or division of operation and management, division conducting digital library work, etc.) must be added to the line and staff organization. 3) For information service division, there must be a certain number of subject specialists. 4) Status of the directorship of university library, librarianship, issue of renaming of university library are also described.

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.

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.

A number of practices for sharing knowledge has been recommended in the literature. These practices, however, are considered to be applicable, universally. This assumption is challenged by this paper which empirically explores the relationship between national culture and knowledge sharing practices in the context of procuring educational buildings in Saudi Arabia. The paper reports on a research study with the aim to identify whether national culture dimensions could be significant variables that impact upon staff preferences in relation to project knowledge sharing practices. The paper critically reviews the literature to identify appropriate measures for knowledge sharing practices. It explores the means by which public sectors professional exchange project knowledge; evaluates policies and level of technical support needed to facilitate knowledge sharing, then proceeds to how employees perceive the benefits they will gain by practicing project knowledge sharing, and their role in this process. The paper tests the relationships among the research constructs based on data collected from 115 project managers responsible for the procurement of educational buildings in Saudi Arabia. The paper provides empirical evidence that the national culture has a significant influence on staff preferences. In light of the research findings the paper concludes with practical recommendations for project knowledge sharing practices that are in line with staff preferences and their cultural orientation. The recommendations should facilitate a more effective application of knowledge sharing practices.
