We experienced an unusual case of accelerated junctional rhythm with severe hypotension after infiltration of lidocaine containing epinephrine during dental surgery under general anesthesia. The patient's electrocardiogram exhibited retrograde P-waves following the QRS complex, which could be misinterpreted as ST-segment depression. As a temporary measure, administration of ephedrine restored the patient's blood pressure to normal levels. The importance of this case lies in its demonstration of an unexpected and serious side effect of commonly used epinephrine infiltration. This case also highlights the need for accurate interpretation of the electrocardiogram and comprehensive understanding of best practices for patient management.

The objectives of this study wre to investigate the effects of two synthetic pyrethroids, bifenthrin(BF) and permethrin(PM), in runoff and to evaluate the effects of suspended solids (SS) in the transport of pyrethroid along the drainage channel. Monitoring of BF and PM was conducted with the runoffs as well as in sediments existing along the drainage channel at a nursery site located in southern California, USA. This study also suggests Best Management Practices (BMPs) to alleviage the pollution caused by heavy usage of pyrethroid insecticides at nursery sites. Due to a high affinity to solid particles of pyrethroid insecticides, the concentrations of BF and PM were proportional to the SS contents along the drainage channel. This study suggests that alleviation of pyrethroids existing in runoffs could be controlled by the removal of suspended solids in runoffs and potential implications of current drainage channels for mitigation of pesticides associated with runoffs.

RFID has fundamental influences on today's business management. This research seeks to formulate the opportunities and challenges, the strengths and weaknesses and the perceived benefits of RFID implementation in three industries: manufacturing, medical-service, and distribution. Ten companies of successful RFID deployment in Korea are presented. Field interview and panel discussion were used to explore the research purpose. The core challenges include RFID readability issues, lack of best practices, increasing prime cost, visible ROI, implementation cost, and employee's resistance. The strengths include IT infrastructure, system integration competency, RFID business model creation ability, executive's support. There is little weakness in Korea companies, there are many perceived benefits in three industries. The most distinctive finding is that the visible ROI was found out in the manufacturing industry, not in the distribution industry. The opportunities and challenges, the strengths and weaknesses and the perceived benefits are some different in three industries, which provide valuable guidance for Korean companies in seeking the RFID opportunities. This case study represents a pioneer research of RFID adoption in Korea.

A major issue for all nuclear stakeholders is to keep the probability of circumstances that could lead to core damage as low as possible. In addition, for NPP, appropriate accident management provisions are to be implemented to limit the consequences associated with an accident. Development and application of L2 PSA is a structured way to demonstrate that such objectives are achieved. The paper presents the efforts recently done in Europe to harmonize some best-practices in that field, from research area to risk assessment. The Fukushima Daiichi accident reiterated the importance of these activities and the need to efficiently reinforce the NPP safety based on risk assessment conclusions. New perspectives in Europe are briefly presented.

많은 건설사업장의 경우 토사 유출에 따른 고농도 탁수가 발생하며, 그 탁도를 낮추기 위해 침전지 혹은 토사탈수백 등의 Best Management Practices(BMPs)를 이용한다. 본 연구에서는 유입되는 탁수에 고분자응집제인 polyacrylamide(PAM)를 액상으로 주입하고, 침전지와 토사탈수백을 통해 탁도를 저감하는 field-scale 실험을 수행하였다. 일반적으로 침전지 중간에는 유입되는 물의 힘을 분산시키기 위해 배플이라는 구조물이 설치되는데, 본 연구결과에 따르면 PAM을 통한 화학적 처리 없이 배플 자체로는 탁도를 낮추는 데 그 효과가 낮았으나, PAM주입을 할 경우 배플 설치 여부에 상관없이 90-98%까지 방류수 탁도를 낮출 수 있는 것으로 나타났다. 침사지 이후에 설치한 토사탈수 백은 그 효과가 낮았으나, 침사지 없이 토사탈수백만 사용할 경우 PAM을 이용한 화학적 처리 없이는 만족할 만한 방류수 탁도를 기대하기 어려웠다. 본 연구결과는 향후 미국에서 면적 10에이커 이상의 공사현장에 적용되는 탁도 규제에 대한 대응 방안으로 PAM을 이용한 탁수 처리의 효용성을 보여준다.

Truffles are cultivated by growing seedlings of compatible tree species in pasteurized substrate amended with truffle spores, maintaining the inoculated seedlings in the greenhouse until the mycorrhizal relationship is established and certified, planting the infected seedlings onto appropriate and properly prepared sites, and managing the resulting truffieres (truffle orchards) to maintain the truffle infections and encourage truffle fruiting. Questions remain to be addressed at each step of the process in developing best management practices for truffle cultivation.

Building restoration is a complex process with a high level of uncertainty. Restoration professionals can significantly benefit from the well-established discipline of project management to achieve their targets; however, available evidence shows that the use of the project management body of knowledge in restoration projects is far from the desired level. Several historical organisations have since been established with the goal of preserving and governing cultural identity, and numerous studies have supported the need of preserving architectural heritage. Many owners, investors, academics, and developers believe that it would be considerably more expensive to renovate and restore an old building than to create a new one. Although the project management process is generally recognised, the concept of project management for architectural heritage projects differs due to the uniqueness of each project. It differs from many construction projects in terms of the need for research-based practices to define scope, planning, scheduling, supervision,decision-making,and also performance. The Greco-Roman Museum in Alexandria's planning, design, and building phases are being studied with the aim of identifying and analysing the variables that contribute to project delays. Three project management pillars were established as a result of gathering this data from the project's stakeholders: the first pillar addresses time management for the existing phase and how it will be incorporated into the new extension phase; the second pillar addresses performance in relation to project management issues in the delivery of the best quality of a construction project; and the third pillar addresses the scope of the new extension because it will significantly impact the other two pillars. This paper argues that a contemporary perspective which utilizes project management tools and techniques can contribute to the conservation of architectural heritage in line with the conservation principles.

Many companies have endeavored to build a quality cost management system in order to be more productive business organization. This study shows the detail procedures of constructing a quality cost management system which is believed to be appropriate for their business system. That is, the method to calculate the quality cost and the linking logic between the quality improvement and its financial impact are explained based on a particular industry case. In this sense, the changes of business performance measures such as market share, customer satisfaction, etc. were analyzed in the longitudinal perspective for the consecutive 4 years (2003~2006). As the quantitative results of this study, the improvement activities based on the quality cost management system resulted in the 32% reduction of quality cost and the 121% increase of business profit, compared 2005 with 2006. In the qualitative perspective, the successive practice of quality cost reduction and the job information sharing in business unit were obtained by providing the best practices and bench-marking cases. Finally, the customer satisfaction has increased so that the customer-friendly management system has been accomplished. With these efforts, the 3.4% increase of the market share and the 3% increase of the customer satisfaction were obtained in 2005. As the future study, the current study can be extended to the concept of COPQ (cost of poor quality) which focuses on the hidden quality cost of the whole business activities. Such extension of analysis will help us understand the wider role of a quality cost management system in the business.

Student records are essential for the functional, social, and personal aspects of the university. However, it is difficult to systematically manage such records because of the vast amount produced by several agents, the decentralization of the university's records management system, and various types and forms produced. Despite acknowledging the importance of student records, Myongji University implements its records management system at a sluggish pace. This study defined students' records except for the administrative records of the university as "student-related records" and categorized them into education records, student creation and research records, and student activity records. After examining the best practices in Korea and abroad, we reviewed the current status of Myongji University's student records management system and proposed appropriate and comprehensive management plans accordingly.
