The application of Giemsa technique to stain compressed diaphragm samples obtained from rodents experimentally infected with Trichinella spiralis is described. Diaphragm samples from rats heavily infected with 20 muscle larvae per gram of body weight(20 ML/gbw) were cut into several pieces and stained with Giemsa; on the other hand, whole diaphragms from slightly infected mice(1 ML/gbw) were also stained with Giemsa. Besides, muscle samples were also stained with Giemsa. Observation at 10 $\times$ magnification revealed that both ML and nurse cells(NC) look as bluish structures clearly contrasting with the pinkish color of the non-infected muscle fibers. NC in the diaphragms of mice could be easily observed at naked eye as blue points contrasting with the pink surrounding areas formed by the non-infected muscle fibers. Among NC observed in the diaphragms of rats infected with 20 ML/gbw, 4.4% was multiple infection. These findings were confirmed in sectioned and hematoxylin-eosin stained specimens. This data could be usefulness for a rapid diagnosis of trichinellosis in post-mortem mammals without magnification procedures.

During the past decades, the application of acoustic emission techniques (AET) through the diagnosis and monitoring of the fracture process in materials has been attracting considerable attention. AET proved to be operative among the other non-destructive testing methods for various reasons including their practicality and cost-effectiveness. Concrete and rock structures often demand thorough and real-time assessment to predict and prevent their damage nucleation and evolution. This paper presents an overview of the work carried out on the use of AE as a monitoring technique to form a comprehensive insight into its potential application in brittle materials. Reported properties in this study are crack growth behavior, localization, damage evolution, dynamic character and structures monitoring. This literature review provides practicing engineers and researchers with the main AE procedures to follow when examining the possibility of failure in civil/resource structures that rely on brittle materials.

지진하중을 받는 현수교의 기하비선형 거동특성을 분석하기 위하여 비선형 지진응답해석 알고리즘을 정립하고 그에 따른 전산프로그램을 개발하였다. 해석이론을 최근 시도되고 있는 자정식 현수교나 mono-duo 형식의 주케이블 형상을 갖는 독특한 현수교에 대해서는 적용가능하도록 유한요소법을 사용하였다. 입력지진은 장지간 교량의 다중지지효과를 고려하기 위하여 한 지점에서 다른쪽 지점으로 형상변화 없이 이동한다고 가정하였다. 하나의 mono-duo 자정식 현수교에 대하여 비선형 지진해석을 수생한 결과 예제의 교량이 비교적 단지간이어서 비선형 거동특성과 다중지지 효과가 두드러지게 나타나지는 않음을 확인할 수 있었다.

The purpose of this study was to develop science research ethics guidelines for elementary school teachers. To develop the guidelines, authors have conducted the following procedures: Development of guidelines through literature reviews; and an application of the developed guidelines to classroom sites. Authors established sections and formats of guidelines for science research ethics through literature reviews and developed contents of major sections and subsections and their explanations and descriptions. After that, authors applied the developed guidelines at elementary science classes and collected data through semi-structured interviews with science class teachers and checklists to reflect on and complement the contents of the guidelines. To secure the validity of guidelines, authors requested a validity assessment to four science education experts and one ethics education specialist. As a result, the CVI for the guidelines was found to be 0.9. Finally, authors developed the final guidelines by adding "Case Examples of Application" by adopting requests of elementary school teachers who used the provisional guidelines.

건설프로젝트에서 설계VE는 그 적용효과가 크므로 체계적 절차에 따른 분석이 요구되며, 그 중 가장 중요한 부분은 우수한 아이디어를 창출하기 위한 창조 단계이다. 하지만 현행 아이디어 창출 방법인 브레인스토밍, 델파이 등을 비롯한 기법들은 아이디어 창출에 많은 시간이 소요되고 우수한 아이디어를 고안한다는 것이 쉽지가 않다. 이는 설계VE에 참가하는 대부분의 전문가들이 아이디 어 창출의 효율성이 떨어지는 방법으로 접근하는데 그 원인이 있는 것으로 판단된다. 이에 본 연구에서는 VE의 효율적 수행을 위한 방법으로 창의적 아이디어 발상기법인 ASIT(Advanced Systematic Inventive Thinking) 적용을 제안하고자 한다. ASIT는 아이디어 고안을 체계적 절차에 따라 수행하도록 지원하여 단기간에 효과적 아이디어를 창출하는데 기여할 것으로 판단된다.

Objective: The aim of this study is to give ergonomists the brief summary of the recently published ISO standards on human-system interaction and tips for application of the standards. Background: Standard developers did hard work on developing a standard in a concise manner. But most of standards are often bulky in volume. Readers of the standards are difficult to catch key points from the voluminous contents of standards and intermingle among them. Method: Focused on newly developed display/control technology, this study reviewed the 14 ISO standards on human-system interaction published during 2008-2013 and summarized key points from them. Results: Schematic diagrams and tables concisely illustrated the processes, procedures, dimensions, or best practices recommended by the standards concerning conception, design, and usability testing for consumer products. Conclusion: The standards provided the minimum level of requirements on design and evaluation on the physical input devices, electronic displays, and control interfaces based on the current state of technology. But the minimum requirements specified in the standards nowadays become mandatory ergonomic requirements in global trade world. Application: Ergonomists can take a quick and broad view on international standardization activities on newly developed display/control technology from this summary study.

PURPOSE. The aim of this study was to determine the frequency of significant panoramic radiographic findings and eventual treatment requirements before conventional or implant supported prosthetic treatment in asymptomatic edentulous patients. MATERIALS AND METHODS. A total of 743 asymptomatic edentulous patients were retrospectively evaluated using a digital panoramic system. We analyzed the radiographic findings, including impacted teeth, retained root fragments, foreign bodies, severe atrophy of the posterior maxillary alveolar bone, mucous retention cysts, soft tissue calcifications and radiopaque-radiolucent conditions. RESULTS. Four-hundred-eighty-seven (65.6%) patients had no radiographic finding. A total of 331 radiographic findings were detected in 256 (34%) patients. In 52.9% (n=175) of these conditions, surgical treatment was required before application of implant-supported fixed prosthesis. However, before application of conventional removable prosthesis surgical treatment was required for 6% (n=20) of these conditions. CONCLUSION. The edentulous patients who will have implant placement for implant-supported fixed prosthesis can frequently require additional surgical procedures to eliminate pathological conditions.
