Purpose: This study investigated the burden of preceptors in order to improve preceptorship in nursing practice. Method: The participants were 170 preceptors at three hospitals in Pusan. The data were collected using questionnaires completed between July and September 2002, which included items to measure burden and opinions to reflect the demands of preceptors. They were analyzed using mean score, frequencies, and content analysis. Result: 1) The preceptors had an average of 6.3 years of clinical experience, while the practical career of a preceptor averaged 1.9 years. The average period of new nurse education was 5.5 weeks. Each year, 1.9 new nurses were trained per preceptor. 2) Of the preceptors 54.7% had received compensation without formal rules. but 54.1% did not want to serve further as preceptors because of overwork, lack of educational preparation, and lack of compensation. They were looking for solutions for existing problems. 3) Preceptors indicated that the major burden was having to repeat explanations to each preceptee, they were too busy to serve as preceptors, and their colleagues' had excessive expectations. Conclusion: We recommend practical management, including supplementary manpower, an education program, and compensation provided by the hospital administration with cooperation from colleges.

The purpose of this study is to identify the practical knowledge about osteoporosis and health promoting behavior possessed by male and female university students in their twenties. Next, the study seeks to analyze the difference in the degree of knowledge and practice of health promoting behavior depending on the students' area of study (health-related or non-health-related major) and previous education about osteoporosis. A survey was given to 300 male and female university students in Jeju Island from November 18 to December 6, 2013. Regarding knowledge about osteoporosis, the accuracy rate of health science major participants was 16.8 % higher than that of those of non-health science, and the accuracy rate of participants with previous education about osteoporosis was 12.9 % higher than those who had not. Health promoting behavior showed a higher degree of practice among students in health-related majors and those with previous applicable education. There were significant differences between the knowledge of osteoporosis and major and the presence and absence of prior education. Regarding the degree of health promoting behavior and major, the presence or absence of prior education showed significant differences. Among male and female students in their twenties, the recognition of knowledge about osteoporosis is very low. There is a need to develop various programs that focus on osteoporosis prevention rather than treatment, to improve the quality of education and training content according to the individual, and to lower the target age for osteoporosis education.

Purpose: This study was done to identify the effectiveness of CPR training for nurses in the 6-sigma course. Method: The participants were nurses and doctors who worked in the medical center. For data analysis, the SPSS/PC14.0 program was used. Result: The total 11 categories of the primary problems were revealed on the recognition of carrying out CPR by nurses and doctors. After understanding the nurses' CPR knowledge and the practical ability, the survey showed 14.97 points and 67.12 points. After the education, the scores were increased from 14.87 to 23.25 in knowledge and from 67.12 to 93.43 in practical ability. The 6-sigma problem was ended as worked up the management plan and understood the changes over the management improving team. Conclusion: This study carries an emphasis on understanding of various CPR performance problems applied with 6-sigma in ward. In addition, improvement activities in relation to policy of hospitals suggest the high possibilities that the application of the improvement activities could be extended into the entire hospitals.

현재 대학에서 수행하고 있는 대표적인 산학협력 교육은 현장에서 직무능력을 향상시키기 위한 현장실습이다. 현장실습의 목적은 전문성을 훈련할 수 있는 기회를 제공하고 취업시장에서 경쟁력을 높이며 이론과 실무를 연계하는 것이다. 이러한 현장실습은 학생들의 실무능력을 증대하기 위해 진행되고 있지만 현장실습 업체와 참여 학생들의 능력에 따라 차이가 많이 발생한다. 심한 경우, 현장에서의 실습 수행이 어려워 단순작업에 학생들을 투입하는 현상이 발생한다. 이러한 현장실습의 문제점으로 인하여 본래의 현장실습의 취지를 달성하지 못하고 있는 실정이다. 이에 따라, 본 논문에서는 Base camp를 이용하여 현장실습의 대한 실습능력을 강화시키고 현장실습을 활성화 시킬 수 있는 방법을 제안하였다.

Purpose: This research was done to identify how PBL education using a simulator affects nursing students' critical thinking, self-efficacy, and meta-cognition by applying and developing a PBL module using the Simman simulator. Method: With a one group pre-post test design, the research was conducted with a convenience sampling on 66 students in C College on Jeju Island for 8 weeks from August to October, 2005. The collected data on critical thinking, self-efficacy, and meta-cognition were analyzed using T-test. SPSS 10.0 was used to assist analysis. For study-related variables, means and standard deviations were used. Results: The finding of the research showed that most of the students were in favor of use of PBL-in the curriculum with more than 50% of the scores indicating satisfaction with content of the teaching, the teaching method, and self-confidence in nursing. The results also showed that there was an increase in interest among the students regarding campus practical education. Conclusion: As the application of the PBL module using the Simman simulator elicited more interest and satisfaction from the students, it is worth using this simulator as a the teaching method to improve the practical education in nursing.

In this paper we suggest a group key agreement protocol among a group consisting more than 3 PKIs. From an 128 bit message, we produce a group key to any length size using a hash function. With a computer experiment we found that PKI's encryption/decryption time is the most dominant part of this procedure and an 160 bit ECC PKI is the most efficient system for distributing an 128 bit message in practical level. We implement this procedure over an unsecure multi user chatting system which is an open software. And we also show that this suggestion could be practically used in military business without a hardware implementation.

Distributed stray inductance exerts a significant influence on the turn-off voltages of power switching devices. Therefore, the design of low stray inductance bus bars has become an important part of the design of high-power converters. In this study, we first analyze the operational principle and switching transient of a T-type converter. Then, we obtain the commutation circuit, categorize the stray inductance of the circuit, and study the influence of the different types of stray inductance on the turn-off voltages of switching devices. According to the current distribution of the commutation circuit, as well as the conditions for realizing laminated bus bars, we laminate the bus bar of the converter by integrating the practical structure of a capacitor bank and a power module. As a result, the stray inductance of the bus bar is reduced, and the stray inductance in the commutation circuit of the converter is reduced to more than half. Finally, a 10 kVA experimental prototype of a T-type converter is built to verify the effectiveness of the designed laminated bus bar in restraining the turn-off voltage spike of the switching devices in the converter.

Soil microbial communities are immensely diverse and complex with respect to species richness and community size. These communities play essential roles in agricultural soil because they are responsible for most of the nutrient cycles in the soil and influence the plant diversity and productivity. However, the majority of these microbes remain uncharacterized because of poor culturability. Next-generation sequencing techniques have revolutionized many areas of biology by providing cheaper and faster alternatives to Sanger sequencing. Among them, amplicon pyrosequencing is a powerful tool developed by 454 Life Sciences for assessing the diversity of complex microbial communities by sequencing PCR products or amplicons. This review summarizes the current opinions in amplicon sequencing of soil microbial communities, and provides practical guidance and advice on sequence quality control, aligning, clustering, OTU- and taxon-based analysis. The last section of this article includes a few representative studies conducted using amplicon pyrosequencing.
