An inter-laboratory comparison campaign on nutrient analysis in seawater was carried out in 2010. Sets of three sterilized seawater samples (Bottle 130, 131, 132) which have enough homogeneity and stability were distributed to 10 laboratories. Participants analyzed the nutrients in their own laboratories (nitrite, nitrate, phosphate, and silicate) at least 5 times and reported the results. Statistical treatments were applied to the results to assess the precision for each laboratory and the discrepancy among laboratories. Most laboratories show within 10% of precision in all nutrient results. Degrees of scattering described as discrepancy among laboratories and relative percent difference values were 4~63% and 0.04~2217%, respectively. The statistical analysis shows that the difference among the laboratories may due to the systematic error rather than random error. When the results were corrected by the results of bottle 130 as a reference material, the degrees of scattering and the relative percent difference were improved significantly. As a result, since most participants show satisfactory precision for nutrient analyses, a use of reference materials which have homogeneity and stability was strongly recommended to improve the comparability of nutrient data.

The global Industry has been shaped by start-ups that originated with knowledge-based innovative strategies or technologies in the 21st century. Specifically, laboratory start-ups that rely on research papers or patents for new technology development are recognized for their high survival rate and the creation of employment opportunities. Our study concentrated on 'I-Corps', which also introduced in Korea, standing for innovation corps is a laboratory startup program launched in 2011 by the NSF(National Research Foundation) to commercialize R&D results and foster entrepreneurship as part of the policy to build a start-up system at the national innovation level. In this study, we proposed and empirically tested a research model focusing on teams participating in the I-Corps program to determine how startup team diversity, among the team characteristics of laboratory startups, affected patent performance. As a result of the analysis, among the proposed variables, age diversity, educational background diversity, and value diversity had a significant impact on patent performance. The results of this study are expected to further strengthen the theoretical and practical foundations of researchers or practitioners of the I-Corps program, as well as related areas involving technology & laboratory startups, intellectual property and knowledge management fields in the future.

리튬이온 배터리는 동작하는 과정에서 필연적으로 열이 발생하기 때문에 적절한 열 관리에 대한 전략이 필요하다. 배터리에서의 발열은 가역적인 발열과 비가역적인 발열로 분류될 수 있으며 배터리의 용도별, 동작 조건 별 발열 특성이 상이하기 때문에, 배터리의 열적 안전성 확보를 위해서는 열적 특성에 대한 분석이 필수적이다. 본 연구에서는 고용량/고출력 리튬이온 배터리의 전기적 특성 실험을 수행하고 열적 안전성 분석을 위하여 발열 특성 분석을 수행하였다. 고용량/고출력 배터리 특성에 따라 가역적 발열과 비가역적 발열이 나타나는 특성이 상이한 것으로 확인되었으며, 또한 온도 측정 정보로부터 배터리의 내부 상태 특성을 추정하고 고장 진단 및 수명 특성에 활용될 수 있음을 확인하였다.

The present study aims to investigate the difference of soundscape evaluation results from on-site field test and laboratory test which are commonly used for soundscape surveys. In order to do this, both field and lab tests were carried out at four different areas in Cheongju city. On-site questionnaire surveys were undertaken to 65 people at 13 points. Laboratory listening tests were carried out to 48 adults using recorded sounds and video. Laboratory tests were undertaken to two different groups who had experience of field survey or not. Also, two different sound reproduction tools, headphones and speakers, were used in laboratory tests. As a result, it was found that there is a very close correlation between sound loudness and annoyance in both field and laboratory tests. However, it was concluded that there must be a difference in recognizing the figure sounds between field and laboratory tests since it is hard to apprehend on-site situation only using visual and aural information provided in laboratory tests. In laboratory tests, it was shown that there is a some difference in perceived most loud figure sounds in two groups using headphones and speakers. Also, it was analyzed that there is a tendency that field experienced people recognize the figure sounds using their experienced memory while non-experienced people can not perceive the figure sounds.

The mouse is one of the most popular experimental animal which has wide variation of strains, diet, environment, breeding technique, and diurnal cycle. Total 731 mice (male 372, female 359) were used for the standard data of our laboratory. Proper age for experiment were $30\pm3$days, body weight were $25\pm2gm (male)$, $23\pm1gm$. (female), minimal diurnal variation showed from 9A.M. to 12P.M.

In this paper, we developed remote control devices that can be controlled passive component e.g. resistor, inductor, capacitor that is a basic element in the electric circuit. We embodied a remote laboratory for basic circuit theory which learners can experiment controlling element value to remote through the internet. It was seen that is useful applying passive component developing to a remote laboratory. Because developed passive components can response in an experiment altering several element values to remote, they will be used very usefully in a remote experiment that equip various experiment theme. Therefor the proposed laboratory will be solved problems of virtual laboratory which students do not handle instruments in engineering experiment. With our proposed system, students can experiment any time, anywhere.

The EPMA analysis for CHIME dating requires standard materials, which include nuclear fuel materials that are rare and sensitive to handle. Any laboratory that does not meet these standards has had difficulties adopting the CHIME dating method. We have developed a working standard technique for CHIME dating to prepare standard materials without use of nuclear fuel materials. Mineral samples, such as small pieces of monazite that are homogeneous in X-ray intensities, are calibrated using well-characterized primary standards in one laboratory. Once this procedure is done, they can be readily usable as working standards in the other laboratories, only with measurement of X-ray intensities. This method is applicable in preparing standard materials for both chemical compositions and determination of X-ray interference correction factors, and it is independent from chemical composition of mineral standard.

본 연구는 기능적 뻗기 검사의 측정자 간 신뢰도를 알아보기 위하여 실시하였다. 본 연구에 참가한 대상자는 총 46명(남 20명, 여 26명)이었고 기능적 뻗기 검사는 두 곳의 실험실에서 이루어졌고 측정자는 총 6명이었다. 같은 장소의 실험실에서 이루어진 검사의 측정자간 신뢰도는 높게 나타났으나 장소가 다른 곳에서 이루어진 검사의 측정자 간 신뢰도는 아주 낮게 나타났다. 따라서 기능적 뻗기 검사의 신뢰도를 확보하기 위하여서는 측정자들의 명확한 기준의 정리가 필요할 것으로 보인다.
