Background: A definite diagnosis should be made in the bovine practice field, however, it was difficult to perform laboratory analysis immediately. Currently, three types of portable blood gas analyzers are available in Korea. Objectives: This study aimed to evaluate the correlations among these three analyzers. Methods: Seventy-two plasma samples from Holstein-Friesian cows were used for blood gas analysis, and three instruments (EDAN i15 Vet, VETSCAN i-STAT, and EPOC) were operated simultaneously. Moreover, plasma calcium levels were compared between these portable analyzers and blood chemistry device, which is usually used in a laboratory environment. Pearson analysis was performed to confirm the correlation of each parameter produced with the three instruments and blood chemistry analyzer. Results: As results, high correlation was observed in parameters of pH, pO₂, potassium ion, ionized calcium, and glucose (p < 0.001, r > 0.7). In addition, pCO₂ showed a moderate correlation among the three analyzers (p < 0.001, r > 0.5), and there was no correlation among all instruments for sodium ions. There was also a high correlation between ionized calcium from the three portable devices and total calcium from the biochemistry analyzer (p < 0.001, r > 0.9). Conclusions: In conclusion, there was a high correlation between results from the three different blood gas analyzers used in the bovine clinical field in Korea. Thus, a consistent diagnosis can be made even with different equipment if the operator is aware of the strengths and weaknesses of each piece of equipment and operates it properly.

Background: For proper monitoring of the eye lens dose, an appropriate calibration factor of a dosimeter and information about the mean energies of X-rays are indispensable. The scattered X-ray energy spectra should be well characterized in medical practices where eye lenses of medical staffs might be high. Materials and Methods: Scattered X-ray energy spectra were experimentally derived for three different types of X-ray diagnostic and therapeutic equipment, i.e., the computed tomography (CT) scan, the angiography and the fluoroscopy. A commercially available CdZnTe (CZT) spectrometer with a lead collimator was employed for the measurement of scattered X-rays, which was performed in the usual manner. Results and Discussion: From the obtained energy spectra, the mean energies of the scattered X-rays lied between 40 and 60 keV. This also agreed with that obtained by the conventional half value layer method. Conclusion: The scattered X-rays to which medical workers may be exposed in the region around the eyes were characterized by means of spectrometry. The obtained mean energies of the scattered X-rays were found to match the flat region of the dosimeter response.

Notwithstanding Korea and P. R.China are located in the neighborhood each other geographically, the break of diplomatic relations of them continued a long term, and the difference of ideology and social structure of two countries was acting as a barrier to understand each other in many fields. Two countries established formal diplomatic relation in 1992, and then the interchange and mutual cooperation between both countries are being performed rapidly, but the field of fisheries education and research system is continuing in the early stage yet. It can be easily expected that the interchange and mutual cooperation in the field of fisheries through the ocean contribute not only to the international friendship, but to the rational management of fisheries resources. In accordence with the necessity mentioned above, the author considered the general situation of fisheries education and research system in P. R. China. P. R. China runs two kinds of fisheries education system which are regular and irregular system. The regular education system is the principal means of cultivating fisheries scientists and technicians. And there are three grade levels in regular education : the tasks of which are undertaken by the fisheries universities, fisheries colleges and fisheries high schools. Adult education system in fisheries are of the following types : fishery cadet training courses, evening schools, correspondence courses and broadcasting or TV programs. The fisheries research in P. R. China is undertaken by the research institutes under the Bureau of Aquatic Products, and the basic research of oceanography is undertaken by the oceanographic institutes under the Chinese Academy of Science.

Three benefits of incorporating writing in engineering curricula are presented. The first benefit is in improving the communication skills which are essential for engineers and are attained through practice. The second benefit is in enhancing learning and is achieved by utilizing the complex process of writing to heighten the level of understanding. The third benefit, though difficult to recognize and even more difficult to promote in a society (and educational institutes) steeped in the behaviorist tradition, is in promoting meaningful learning by cultivating motivation internal to students themselves. The boundaries of writing activities are broadened to include that of stating a paragraph or even one complete sentence such that it may be incorporated in engineering without undue strain. A two-year trial of incorporating four types of writing assignments in six different courses (a total of 12 classes) at Michigan Technological University shows that writing assignments can be designed to achieve different degrees of the three aforementioned benefits. It is found that different types of writing activities need to be assigned depending on the status of course (elective vs. required) and on the composition of the students taking the course (upper division vs. lower division; majors vs. non-majors).
