  • The objective of this study was to suggest conducting a preliminary investigation into renaming the clinical laboratory science degree by comparing the names of this degree used in Korea, Japan, Taiwan, and the United States. In Korea, students who graduate from clinical laboratory science departments at universities are awarded a Bachelor of Science in Health Science, a Bachelor of Science, or a Bachelor of Clinical Laboratory Science, while graduates of clinical laboratory science departments at colleges receive an Associate Degree in Health Science or an Associate Degree in Clinical Laboratory Science. The Bachelor of Science in Clinical Laboratory Science and the Associate of Science in Clinical Laboratory Science are internationally accepted designations. They reflect the academic identity and professionalism of the occupation. The Bachelor of Science in Health Science and the Associate Degree in Health Science, being used by the Department of Clinical Laboratory Science in Korean schools, can be renamed to the Bachelor of Science in Clinical Laboratory Science and the Associate of Science in Clinical Laboratory Science, uniform names, respectively, through the revision of the school regulations.

  • The purpose of this study was to analyze of how the elementary school teachers lead their classes of a science laboratory instruction and an engineering laboratory instruction in a science subject class. For this study, science laboratory and engineering laboratory lessons were selected and for each science and engineering laboratory lesson, five elementary school teachers were video-recorded of their lessons. The science and engineering laboratory lessons were analyzed by utilizing processes of the science model and the engineering model based on Schauble et al. (1991). The results of these studies are as follows: In science laboratory instruction, some participants didn't distinguish the difference between the science laboratory goal and the engineering laboratory goal. All of participants used search and end strategy of engineering laboratory for science laboratory lesson. In engineering laboratory instruction, all of participants guided to students engineering laboratory goal and used inferences and search strategy of engineering laboratory. However they didn't use the trial and error strategy or redesign which can be an essential element in engineering and design process. Educational implications are discussed.

  • 이 연구는 임상병리검사학(또는 임상검사과학, 의학검사과학, 의생명검사과학)에 대한 체계적 인 접근을 하기 위해 임상병리검사학의 정체성과 학문분류체계를 가지고 논의하였다. 임상병리검사학은 한국 연구재단의 학술연구분야분류에 등재되어 있지 않다. 국내에서는 1963년 임상병리검사학과 최초로 신설된 이후 전국에 임상병리검사학과가 52개에 이르고 있다. 학문적 정체성에도 불구하고 제도적으로 임상병리검사학은 전문적 영역을 확보하지 못하고 있는 실정이다. 학술연구분야분류를 보면 물리치료학, 작업치료학, 치위생학은 체계적으로 분류되어 그 학문성을 인정받고 있다. 이 연구는 임상병리검사학의 새로운 학문분류체계이다. 내용 연구는 다음과 같이 요약된다. 임상병리사의 학문은 대분류 의약학, 중분류 임상병리학, 소분류 임상병리검사학에 위치한다. 세분류의 학문용어는 "혈액수혈학, 면역생화학, 미생물기생충학, 유전분자생물학, 조직세포학, 심폐신경생리학"으로 구성한다.

  • Objective: A study was conducted to test six threonine (Thr) levels (0.39%, 0.44%, 0.49%, 0.54%, 0.59%, and 0.64%) to estimate the optimal dietary Thr requirements for Longyan laying ducks from 17 to 45 wk of age. Methods: Nine hundred Longyan ducks aged 17 wk were assigned randomly to the six dietary treatments, where each treatment comprised six replicate pens with 25 ducks per pen. Results: Increasing the Thr level enhanced egg production, egg weight, egg mass, and the feed conversion ratio (FCR) (linearly or quadratically; p<0.05). The Haugh unit score, yolk color, albumen height, and the weight, percentage, thickness, and breaking strength of the eggshell did not response to increases in the Thr levels, but the albumen weight and its proportion increased significantly (p<0.05), whereas the yolk weight and its proportion decreased significantly as the Thr levels increased. Conclusion: According to a regression model, the optimal Thr requirement for egg production, egg mass, and FCR in Longyan ducks is 0.57%, while 0.58% is the optimal level for egg weight from 17 to 45 wk of age.

  • Species identification using DNA sequences is the basis for DNA taxonomy. In this study, we sequenced the ribosomal large-subunit RNA gene sequences (3,037-3,061 bp) in length of 13 Chinese Theileria stocks that were infective to cattle and sheep. The complete 28S rRNA gene is relatively difficult to amplify and its conserved region is not important for phylogenetic study. Therefore, we selected the D2-D3 region from the complete 28S rRNA sequences for phylogenetic analysis. Our analyses of 28S rRNA gene sequences showed that the 28S rRNA was useful as a phylogenetic marker for analyzing the relationships among Theileria spp. in ruminants. In addition, the D2-D3 region was a short segment that could be used instead of the whole 28S rRNA sequence during the phylogenetic analysis of Theileria, and it may be an ideal DNA barcode.
