This study was conducted for the university students who majored in culinary arts. The effects of students' certifications on class and school life satisfaction and their effects on preparation employment were examined. The results showed that the students with the certifications had a high level of satisfaction in the class satisfaction, but they also had high stress in the school life. In other words, it seemed that the stress was increased in parallel with the school life in obtaining the certificate. In the case of qualification for preparation employment, the certification affects the preparation for employment even for the culinary arts majors. As for the number of certificates and passions, the change was found from 3 certifications, lower in 4, but again in 5. These results suggest that the certification initially increases enthusiasm, but when it reaches a certain level, it reaches its limit and it rises again after passing the interval. Also, students who graduated from cooking related high school showed high passion compared to those who did not.

This study investigated the academic achievement of science and high school students according to the characteristics of R&E activities in mathematics and science. In addition, based on the survey results, the correlation between R&E activity characteristics and mathematics and science academic achievement was studied through correlation analysis and factor analysis between subjects. There was a difference in academic achievement in mathematics and science according to the characteristics of the R&E activity area, and the experience of R&E activity was found to be closely related to the academic achievement of related subjects. Depending on the area of R&E activity, mathematical and scientific academic achievement was found to be two factors: mathematical logic and natural understanding. Natural understanding factors significantly influenced students' academic achievement in mathematics, physics, and life sciences, and mathematical logic factors significantly influenced the academic achievement of students in chemistry and earth science subjects. In particular, mathematical logic ability was concentrated in excellent physics class students, and natural understanding ability was concentrated in excellent life science class students. Since the characteristics of the R & E activity area greatly influence the academic achievement of mathematics and science, it will significantly contribute to the selection and operation of the R & E activity area of science high school students.

Objective: Microminipig (MMP) is a miniature pig with an extra small body size for experimental use. In the present study, the occurrence of stillbirths and their genetic association with swine leukocyte antigen (SLA) class II haplotypes were evaluated in a population of MMPs. Methods: The occurrences of stillbirth and genetic association with SLA class II haplotypes using 483 stillborn and 2,246 live piglets, and their parents were compared among the three groups of newborn piglet litters; an all stillborn (AS) group consisting of only stillborn piglet litters, a partial stillborn (PS) group consisting of stillborn and live piglet litters, and an all alive (AA) group consisting of only live piglet litters. Results: The incidence of stillborn piglets was 483/2,729 (17.7%). Distributions of litter sizes, numbers of stillborn piglets in a litter, parities, and gestation periods were distinct among the three groups. The frequencies of low resolution haplotype (Lr)-0.7 or Lr-0.23 were higher in the AS group than in the PS or AA groups. In sires, the frequency of Lr-0.7 associated with the AS group was significantly higher in the AS group than with the AA group. In dams, the frequency of Lr-0.23 was significantly higher in the AS group than in the PS or AA groups, whereas the frequency of Lr-0.7 was not significantly different. Conclusion: The incidence of stillborn piglets in MMPs appears to be higher than those in other pig breeds. Several traits related with stillbirths such as the number of stillborn piglets and parities of the AS group were different from those of the PS and AA groups. Specific SLA class II haplotypes were associated significantly with a high incidence of stillbirths and could be used as genetic markers to adopt breeding strategies to lower the rate of stillbirth in MMPs.

The β-class of carbonic anhydrases (β-CAs) are zinc metalloenzymes widely distributed in the fungal kingdom that play essential roles in growth, survival, differentiation, and virulence by catalyzing the reversible interconversion of carbon dioxide (CO₂) and bicarbonate (HCO₃^-). Herein, we report the biochemical and crystallographic characterization of the β-CA CafA from the fungal pathogen Aspergillus fumigatus, the main causative agent of invasive aspergillosis. CafA exhibited apparent in vitro CO₂ hydration activity in neutral to weak alkaline conditions, but little activity at acidic pH. The high-resolution crystal structure of CafA revealed a tetramer comprising a dimer of dimers, in which the catalytic zinc ion is tetrahedrally coordinated by three conserved residues (C119, H175, C178) and an acetate anion presumably acquired from the crystallization solution, indicating a freely accessible "open" conformation. Furthermore, knowledge of the structure of CafA in complex with the potent inhibitor acetazolamide, together with its functional intolerance of nitrate (NO₃^-) ions, could be exploited to develop new antifungal agents for the treatment of invasive aspergillosis.

High school common science is introduced by the sixth national curriculum. It consists of physics, chemistry, biology and earth science like the secondary school science. In this paper, textbooks are analyzed by the science teachers and the status of the present teaching and learning methods is reported. The detailed results are as follows; 1. Almost high school teachers choose textbook that included little the STS material. More than two teachers are teaching the high school common science and when they are chosen, they are independent with their major. 2. According to the national curriculum, they evaluated the textbooks as it is below the middle level. This evaluations are not dependent on teachers' comparement and textbook's class except the several matters based on STS (science-technology-society). 3. The teacher teaching the high school common science thought that teaching the textbook in school is worse than analysizing it. they must have emphasised on learning of inquire method than system of knowledge, introduction to material connected with real life and STS in the high school common science.

본 연구는 문제풀이 중심으로 운영되는 고등학교 생명과학 수업에서 교육매체의 일종인 교실응답시스템(CRS)의 활용 가능성을 알아보고자 하였다. 교수 학습 전략으로 CRS 활용반(34명)은 학생들이 CRS단말기로 응답한 결과를 교사가 즉시 파악하고 개인별 응답 이유를 질문한 후 피드백을 하였다. 비교반(35명)에서는 CRS를 사용하지 않았으며 학생들에게 일괄적인 피드백을 하였다. 연구 결과, CRS 활용이 학생들로 하여금 수업 활동에 흥미와 집중력을 높여주는 것으로 인식되었다. 그러나 학업 성취도의 향상에 있어서 CRS 활용반과 비교반 사이에 유의한 차이는 없었다. 다만 성적 수준에 따라 그룹을 나누었을 때, 중위그룹에서는 CRS 활용반과 비교반 사이에 학업 성취도의 향상에 유의한 차이를 보였다. 진단평가 및 형성평가에서 CRS 활용의 효과를 높이기 위해서는 다양한 수준의 문제들을 사전에 개발하고, 학생들의 응답 이유를 정확히 파악하여 더욱 많은 학생들에게 개인별 맞춤형 피드백을 할 수 있는 교수 전략의 개발이 필요함을 제안한다.
