The purpose of the study is to develop effective teaching methods to strengthen the major learning capabilities of electronic engineering learners through inquiry learning using computing thinking ability. To this end, first, in the electronic engineering curriculum, we performed teaching-learning through an inquiry and learning model related to mathematics, probability, and statistics under the theme of various majors in electronic engineering, focusing on understanding computing thinking skills. Second, an efficient electronic engineering subject inquiry class operation using computing thinking ability was conducted, and electronic engineering-linked education contents based on the components of computer thinking were presented. Third, by conducting a case study on inquiry-style teaching using computing thinking skills in the electronic engineering curriculum, we identified the validity of the teaching method to strengthen major competency. In order to prepare for the 4th Industrial Revolution, by implementing mathematics, probability, statistics-related linkage, and convergence education to foster convergent talent, we tried to present effective electronic engineering major competency enhancement measures and cope with innovative technological changes.

Cytoplasmic male sterility (CMS), one of the most important traits in crop breeding, has been used for commercial seed production by $F_1$ hybrid cultivars of pepper (Capsicum annuum L.). To develop reliable molecular markers for allelic selection of the Restorer-of-fertility (Rf) gene, which is known to be a major determinant of pollen fertility restoration in peppers, a sequence of approximately 10 kb flanking an RAPD fragment closely linked to the Rf locus was obtained by genome walking. A homology search revealed that this sequence contained an LTR retrotransposon and a non-LTR LINE-like retrotransposon. Sequencing of this Rf-linked region to search for polymorphisms between a dominant and recessive allele revealed 98% nucleotide sequence identity between them. A third polymorphic haplotype of the Rf-linked sequence, which has 94-96% nucleotide sequence identity with the two previously isolated haplotypes, was identified among a large number of breeding lines. Utilizing polymorphic sequences in the haplotypes, PCR markers were developed for selection of particular haplotypes and used to examine the distribution of the haplotypes in diverse breeding lines, cultivars, and C. annuum germplasms. Surprisingly, the third haplotype was the predominant type in C. annuum germplasms, while its frequency in $F_1$ hybrid cultivars was relatively low. Meanwhile, analysis of breeding lines whose Rf allele genotypes and male-sterility phenotypes were already known revealed that the third haplotype was mainly present in exotic breeding lines that cause unstable male-sterility when combined with sterile cytoplasms.

The crude biopolymer (AS-S1) and endobiopolymer (AS-S2) were isolated from the dry stem bark of Acanthopanax sessiliflorus and tested for anti complement activity. The two potent anticomplement biopolymers, AS-1 and AS-2-Fr.I, were isolated by the combination of ion-exchange chromatography and gel filtration methods from the endo-biopolymers (AS-S2). The anticomplement activity of AS-1 (MW 12 kDa) and AS-2-Fr.I (MW 180 kDa) were found to be 84.4% and 100.0%, respectively, at the concentration of $25{\mu}g/ml$. Activated pathway of the complement system occurred in both classical and alternative pathways, as evidenced by crossed immunoelectrophoresis(CIEP), where a major pathway was detected to be the classical one. It was found that the anticomplement activities of the periodate oxidized were decreased significantly, but those of pronase digested biopolymers of AS-1 and AS-2-Fr.I were decreased very little. The AS-1 contained 2,4,6-tri-O-methyl-D-glucitol, 2,3,6-tri-O-methyl-D-galacitol, and 2,3,6-tri-O-methyl-D-galacitol, which indicated that AS-1 contained a $(1{\rightarrow}3),\;(1{\rightarrow}4)-linked$ glucopyranosyl residue and a $(1{\rightarrow}4)-linked$ galactosyl residue. AS-2-Fr.I contained mainly 2,4-di-O-methyl-D-mannitol and 2,3,4-tri-O-methyl-D-galacitol, which contained $(1{\rightarrow}3),\;(1{\rightarrow}6)$ linked mannosyl and $(1{\rightarrow}6)$ linked galactosyl residues.

Total elbow prostheses which are now available in clinical use can generally be classified into two major categories ; one bing linked prostheses, another being unlinked prostheses. Of those two categories I am dealing here only with the problems of the unlinked type prosthesis, particularly with those of non-constrained, surface-replacement prostheses. Furthermore, my presentations this time may have to be narrowed down only to the topics regrading the particular features and some of the technical problems with Kudo Elbow Prosthesis, due to the time limit assigned for this presentation.

The FimH subunit of type 1-fimbriated Escherichia coli has been determined as a major cause of urinary tract infection. To produce a possible vaccine antigen against urinary tract infection, the fimH gene was genetically linked to the Itxa2b gene, which was then cloned into the pMAL -p2E expression vector. The chimaeric construction of pMALfimH/Itxa2b was transformed into Escherichia coli TB1 and its N-terminal amino acid sequence was analyzed. (omitted)

N-acetylneuraminic acid is one of the major derivatives of sialic acid. is widely distributed in mammalian cells as the ${\alpha}$2-3- or ${\alpha}$2-6-linked nonreducing terminal residue of oligosaccharide chains of glycoconjugates, and plays important structural and functional roles at the cell membrane surface. The analysis of sialylated glycoproteins is an important part of glycoprotein characterization, especially because sialylation or desialylation in oligosaccharides often causes dramatic changes in the function of glycoproteins.

Technical high school aims at educating students to acquire fundamental skill and technology required for being competent technicians, to be creative in adjusting themselves to the changing industrial society, and to do self-realization and find their ways toward the future on their own. To attain that goal and maximize learning effect, mathematics education is very important as prerequisite learning for technical subjects, as most technical courses in technical high school are basically based on mathematics. The purpose of this study was to discuss how mathematics education could be successfully linked to technical courses in an attempt to make it function properly as prerequisite learning for major subjects and facilitate students' technical learning. For that purpose, what problems the mathematics components of major subjects and the curriculum had was examined and the way to offer better education was presented. And there are some suggestions regarding mathematics education: First, technical mathematics should be newly inserted into technical high school curricula to help students learn major subjects in more efficient way. Second, most technical high schools are expected to just require tenth graders to complete a 10-stage mathematics course. In that case, they might find difficulties in learning major subjects when they are in their 11st and 12th grade. The curriculum should be designed to have 11st and 12th graders take mathematics education. Third, many students find a job after graduation, but the growing number of students go on to university to receive more education in the same field. Accordingly, there is a need to enlarge continuous progress plan, rather than completion-type one, to make students well-grounded technically. And mathematics should be taught in more classes as prerequisite subject for major courses. Fourth, mathematics elements necessary for each major subject should be outlined and announced to schools so that they could reorganize mathematics and major courses appropriately.
