| Title Alternative | Some topologies on stable groups |
| FullText URL | 004_027_029.pdf |
| Author | Tanaka, Katsumi| |
| Abstract | In the theory of Linear algebraic groups, Zariski topology plays a crucial role. We introduce some topologies on general abstract groups generalizing Zariski topology in some sense. Especially we focus on stable groups, because not only the similarity of them with respect to some structure theorems but also we are interested in stable groups for their own right. In Linear algebraic groups, they have a descending chain condition on closed sebsets. Hence we may introduce some topologies on stable groups in order to satisfy the descending chain conditions on closed subsets whatever the topology is. According to this guide line we introduce some topologies stable groups and omega-stable groups. |

| Title Alternative | Model theory of doubly transitive groups |
| FullText URL | 008_1_001_006.pdf |
| Author | Tanaka, Katsumi| |
| Abstract | 2重可移群には,near-domainを解釈することができ(定理13), またnear-domainから2重可移群を構成することができる｡つまり,2重可移群の研究はnear-domainの研究と同値になる｡ここで,有限のnear-domainがnear-fieldになることは知られているが,無限のnear-domainがnear-fieldになるかどうかは知られていない｡これに関連して,無限の2重可移群についても多くの未解決問題が残されている｡このノートでは,これらの問題にたいするモデル論的なアプローチ(Morley rank有限の場合の構造析,geometricな方法など)をいくつか紹介する｡ |
| Abstract Alternative | It is well known that we can interpret a near-domain in a doubly-transitive group and we can consruct a doubly-transitive group by a near-domain. This shows the equivalence of the study of doubly-transitive groups and that of near-domains. It is known that every finite near-domain is a near-field, however, it is open in infinite case. We investigate several open problems in this subject and some model theoretic approaches (in case of finite Morley rank, geometric) to them. |

| Abstract | Novel glycine oxidase (GlyOX) from Marinomonas mediterranea depends on cysteine tryptophilquinone (CTQ) and catalyzes the oxidative deamination of glycine to produce a glyoxylate, ammonia, and hydrogen peroxide. M. mediterranea GlyOX genes (goxA and goxB) were cloned and recombinant GlyOX was heterologously expressed by E. coli. The purification of recombinant GlyOX was carried out by metal affinity and DEAE-Toyopearl 650M column chromatographies. M. mediterranea GlyOX was homotetramic with a molecular mass of 76kDa and showed optimum activity around 30°C and at pH 5.0, and stability below 50°C and between pH 5.0 to 9.0. M. mediterranea GlyOX shows a strict substrate specificity toward glycine, and the Michaelis constant for glycine was 0.5mM. M. mediterranea GlyOX could determine the quantity of glycine in human serum and human blood plasma with high sensitivity. This study revealed the catalytic and structural properties of M. mediterranea GlyOX with high substrate specificity. |

| Title Alternative | A Case Study on How to Teach English at University Adopting TOEIC (2) -Evaluation after three years- |
| FullText URL | 009_167_178.pdf |
| Author | Morokawa, Shigetake| Ogino, Masaru| Kanzaki, Ken-ichi| |
| Abstract | Three years ago, we wrote an essay about our new English-teaching program that adopted TOEIC. We gave out questionnaires to the students with questions ranging from what they thought of English in general to what they thought of our new program. In the essay, we discussed some of the results. Even though students' response was relatively positive in this initial survey, we wrote in our conclusion that we would like to renew and reform our classes. Receiving feedback from students periodically would help us improve their English ability. In order to see the change of students' attitude toward English and also toward our program, we conducted the same research last February. This time the results were not as favorable. For example, the number of students who thought their English ability was poor increased and those who showed a positive attitude toward our program decreased. We discussed and wrote what we learned from those results. We raised the question whether there was a gap between what we tried to teach to the students and what they wanted from us. Possible reasons were discussed on why we could not succeed in stimulating the students into studying English further. In April 2003 Okayama University started a new English curriculum, in which the classes for proficiency tests including TOEIC were opened. Similar classes have been set at many other universities. This survey will be a help to the further development of English education adopting TOEIC. |

| Abstract | An elementary proof of permanence for a simple mathematical model proposed by Nowak and Bangham. In many papers, permanence property is proved by theorems established by the general theory of dynamical system. In this paper, we present an elementary proof only using differential inequalities and the theory of linear differential equations with constant coefficients. |

| Title Alternative | On Persistence in Dynamical Systems (Review) |
| FullText URL | 010_013_021.pdf |
| Author | Sasaki, Toru| Kajiwara, Tsuyoshi| |
| Abstract | Some important results on persistence are reviewed. These results concern the behavior of the orbits approaching the boundary. The orbits restrict the flow on the boundary, if one of them approaches more than one invariant set. A typical example is a model for cyclic competition, where the heteroclinic cycle can be the ω-limit set. Thus the persistence can be reduced to some conditions on the boundary flow. |

| Abstract | Dynamics of infectious disease in vivo is described by coupled differential equations. Stability analysis of the complicated systems is difficult without computer calculation, while stability analysis is, in general, important to investigate qualitative behaviour of models. Liu analyzes stability of systems describing HIV dynamics in vivo with a symbolic calculation software. The same method is used for stability analysis of a mathematical model of malaria. |

| Author | Morokawa, Shigetake| Kanzaki, Ken-ichi| Ogino, Masaru| |
| Abstract | We tried an experiment to see whether or not it was possible to teach English considering the rising emphasis on TOEIC. Each of the three of us was in charge of five lessons out ot fifteen. One taught a section in listening in a language laboratory, another taught a section in grammer and vocabulary, the third taught a section in reading. There was no exam at the end of the semester, but mini-TOEIC tests were administered, and taking the TOEIC was mandatory. Students were evaluated on both their mini-tests and their TOEIC scores. Student evaluations reflected a positive attitude toward the course. Most students favored the standard of TOEIC as a test of course evaluation. Although we realize there are aspects to be improved (i.e., students' listening ability, class-time efficiency), we should continue to develop English ability focusing on the internationally established medium, TOEIC. |
