  • Four oxovandium(IV) complexes with carboxylate ligands, $VO(picn)_2$, $VO(htmq)_2$, $VO(quin)_2$ and $VO(pyra)_2{\cdot}2H_2O)$ have been prepared and studied. Infrared spectral data coupled with the results of magnetic susceptibility study strongly suggest that there are relatively strong intermolecular interactions in $VO(picn)_2$ and $VO(htmq)_2$. In all oxovanadium(IV) complexes studied in this work, the carboxylate ligand coordinates to the metal ion in the unidentated fashion. Some fundamental vibration modes of oxovanadium(IV) complexes were empirically assigned from the difference in the spectrum of metal complex with free ligand.

  • The cationic polymerization of cyclic acetals are investigated theoretically using the semiempirical MINDO/3, MNDO, and $AM_1$, methods. The nucleophilicity and basicity of cyclic acetals can be explained by the negative charge on oxygen atom of cyclic acetals. The reactivity of propagation in the polymerization of cyclic acetals can be represented by the positive charge on $C_2$ atom and the low LUMO energy of active species of cyclic acetals. The reactivity of 2-buthyl-1,3-dioxepane(2-Bu-DOP) of cyclic oxonium and opening carbenium ion form is expected computational stability of the oxonium ion by 5${\sim}$7kcal/mole favoring the carbenium ion. Owing to the rapid equilibrium of these cation forms and the reaction coordinate based on calculation that the reaction coordinate based on calculation that the chain growth $S_N1$ mechanism will be at least as fast as that for $S_N2$ mechanism.

  • A new analytical luminescence method for the Tb+3 and Eu+3 ions was studied using the fluorescence enhancement of the ions on the TLC plate. Compared to the specific emission intensities of the ions in aqueous or ethanol solution, if spotted on the TLC plate, the line intensities were extremely enhanced. There was additional enhancement effect of the lines from the ions on the TLC plate, if treated with ο-phenanthroline. Based on the luminescence enhancement, the detection limit of the ions was lowered more than 6 order of magnitude compared to the luminescence method using solution samples. The energy-transfer mechanism was also explained for the theoretical back ground of the luminescence enhancement.

  • Even though Mesozoic Mudeungsan tuff, located within Neungju Basin, has been named several rock names, it should be named as Mudeungsan tuff due to several evidences, such as fiamme, welded texture and rock fragments in the Mudeungsan tuff. Volcanic eruption boundary between the Cheonwangbong and Anyangsan areas is not clear, but petrochemical and mineral chemical evidences with different ages indicate clear petrological boundary between Cheonwangbong and Anyangsan. The Mudeungsan tuffs from Cheonwangbong and Anyangsan is welded crystal tuff with dacitic composition and were generated from cogenetic calc-alkaline magma in the volcanic arc environment. Geochemical events indicate that magma beneath Cheonwangbong was seems to have been evolved from the magma beneath Anyangsan due to fractional crystallization dominated by plagioclase.

  • The purpose of this study is to analyze how the task group functioning and need styles have influence on role conflict and role ambiguity as the employee's personality engaged in the service industry such as a hotel. This study uses the hierarchical regression analysis method. Data were collected by the survey method from employees engaged in the service industry such as a hotel located Seoul, the Province of Gyeonggi, and the Province of Gangwon. The study result shows that to the employees in the type A and type X styles, the task group functioning and need styles are not significantly related to the role conflict. But to the employees in the type B style, the task group functioning and need styles are significantly related to the role conflict. And the result shows that to the employees in the type B style, the lower the faith in peers and management, the more the role conflict occur. On the other hand, the study result shows that to the employees in the type A styles, the task group functioning is significantly related to the role ambiguity. And to the employees in the type B style, the higher the faith in peers and management, the more the role ambiguity occur. On the contrary, to the employees in the type X style, need styles are significantly related to the role ambiguity. But to the employees in the type X style, the higher the need for achievement, the more the role ambiguity occur. On the other hand, the study result shows that to the employees in the type B styles, the task group functioning and need styles are significantly related to the role ambiguity. And to the employees in the type B style, the higher the need for achievement, the more the role ambiguity occur or the lower the confidence in peers and management, the more the role ambiguity occur. Although this study provides several managerial implications, this study has some limitations. Specifically data were collected from only the hotel industry in Seoul, the Province of Gyeonggi, and the Province of Gangwon. In spite of the limitations, the study results could be used valuably in case of the personnel managers which manage the employees under the conflict situations.

  • Enolase is one of the glycolytic enzymes, which are involved in a central energy metabolism present in nearly all organisms. In Escherichia coli, enolase constitutes RNA degradosome with RNase E, PNPase and RNA helicase, which are involved in most mRNA degradation and RNA processing. Recently, it has been reported that RNase G, an RNase E homolog, degrades eno mRNA. To examine a functional role of RNase G in enolase expression which is known to be up-regulated under microaerobic condition, we carried out experiments. Here, we report that expression levels of enolase and RNase G are not correlated under microaerobic condition. Based on this observation, we suggest the existence of an unknown factor(s) which regulate the activity of RNase G or enolase mRNA under microaerobic conditions.

  • This study examined the relationship among perception on information, purpose of information use, and trust in government. It also identified different patterns of groups by their ideological inclination via a national survey on sample population over the age of twenty. The result showed the statistical significance of the relationship among information perception, purpose of information use, ideological inclination, and trust in government. The analysis result implies that the role of government should be readjusted in terms of publicness toward meta-data provider which is transparent and fair without any discrimination by individual difference and economic condition. This will increase the level of trust in government data and its utilization will be tied into the individual connectedness for social integration. The role of government as an information provider needs to establish the role of mediator which always keeps social rules and tracks down violators in a timely manner in the process of information production. With transparent information flow and fair game, the richness of information and a positive production environment will be created.

  • Ba-Ferrite single crystals were prepared and the magnetic and thermal properties were characterized by Mossbauer spectroscopy. The single crystal layer was cut in the c-axis and radiated to the surface by ${\gamma}$-rays for Mossbauer spectroscopy. We found out that the spin states in Fe ions were parallel to the ${\gamma}$-rays direction and the whole crystal bulk formed only one crystal with the same spin direction. $M\"{o}ssbauer$ spectra in single crystal have only 4 sets of 4 absorption lines in each Fe site when the ${\gamma}$-rays have the same radiation direction with the c-axis in the crystal, and there was no 2b-site spectrum. The zero absorption of 2b-site means that there was a fast diffusion motion in a double-well atomic potential at room temperature, in which bipyramidal Fe ions have the two minima at each side mirror plane.

  • The purpose of this study is to review how to introduce a division algorithm in mathematics textbooks which were applied 2009 revised curriculum. As a result, the textbooks do not introduce the algorithm in the context of division by equal part. The standardized division algorithm was introduced apart from the stepwise division algorithms and there is no explanation in between them. And there is a lack connectivity between activities and algorithms. This study is expected to help new curriculum and textbook to introduce division algorithm in proper way.
