  • Using the criteria of previous study, we analyzed the morphological characters of 66 specimens of the Sebastes pachycephalus complex collected from Korea between 2008 and 2013. As a result, the 37 specimens were identified as Sebastes nudus, and the remaining specimens as Sebastes pachycephalus. Sebastes nudus is characterized by the absence of scales below the base of the dorsal fin spines; the absence of dark spots on the dorsal, anal, and caudal fins; and the presence of distinct yellow or brownish-red markings on the dorsum (when fresh). The most similar species S. pachycephalus differs from S. nudus in having minute scales below the base of the dorsal fin spines. We propose the new Korean name "Hwang-jeom-gae-bol-rak" for S. nudus, and redescribe S. pachycephalus.

  • A general model of equations of the two-temperature theory of generalized thermoelasticity is applied to study the wave propagation in a fiber-reinforced magneto-thermoelastic medium in the context of the three-phase-lag model and Green-Naghdi theory without energy dissipation. The material is a homogeneous isotropic elastic half-space. The exact expression of the displacement components, force stresses, thermodynamic temperature and conductive temperature is obtained by using normal mode analysis. The variations of the considered variables with the horizontal distance are illustrated graphically. Comparisons are made with the results of the two theories in the absence and presence of a magnetic field as well as a two-temperature parameter. A comparison is also made between the results of the two theories in the absence and presence of reinforcement.

  • The purpose of this study was to identify differences in stress, interpersonal relations, learning perceptions and self-efficacy of nursing students participating in team based learning simulation practices. The study group consisted of 24 students in the third grade who attended nursing college. Data were collected using questionnaires. The collected data were analyzed by SPSS 22 version's descriptive statistics, t-test, and paired t-test. The results showed that stress and learning perceptions were significantly different according to gender, leave of absence in pre and post - test. After the practice of team - based simulation, the stress of nursing college students decreased and interpersonal relations and self - efficacy were improved. The results of this study showed that nursing students' gender and absence of school should be considered in the team - based simulation. Further research on team based simulation practice involving interpersonal relationships is needed.

  • Interleukin-32 (IL-32) is a cytokine inducing crucial inflammatory cytokines such as tumor necrosis factor-${\alpha}(TNF{\alpha})$ and IL-6 and its expression is elevated in various inflammatory autoimmune diseases, certain cancers, as well as viral infections. IL-32 gene was first cloned from activated T cells, however IL-32 expression was also found in other immune cells and non-immune cells. IL-32 gene was identified in most mammals except rodents. It is transcribed as multiple-spliced variants in the absence of a specific activity of each isoform. IL-32 has been studied mostly in clinical fields such as infection, autoimmune, cancer, vascular disease, and pulmonary diseases. It is difficult to investigate the precise role of IL-32 in vivo due to the absence of IL-32 gene in mouse. The lack of mouse IL-32 gene restricts in vivo studies and restrains further development of IL-32 research in clinical applications although IL-32 new cytokine getting a spotlight as an immune regulatory molecule processing important roles in autoimmune, infection, and cancer. In this review, we discuss the regulation and function of IL-32 in inflammatory bowel diseases and rheumatoid arthritis.

  • The optimized RAPD-PCR conditions, which can be utilized as a basic information for the analysis of the genetic characteristics were investigated with four onion varieties, named Changryungdaego, Yeoeuijuhwang, Yakwangju, and Dabonghwang using Operon primers, OPR01 (TGCGGGTCCT) and OPZ20 (ACTTTGGCGG). We tested several concentrations of DNA, primer, and MgCl2, annealing temperature, number of PCR cycle, and presence/absence of pre-heating time at the begining of PCR reation in the 25${mu}ell$ volume. The best RAPD profiles were obtained using 50ng of DNA, 5mM of primer, 1.5mM of MgCl2, 45$^{\circ}C$ of annealing temperature and an absence of pre-heating time. An establishment of the stable and reproducible RAPD-PCR conditions are expected to be useful for the subsequent RAPD-related investigation, such as genetic characterization of the onion strains, re-establishment of phylogenetic relationships and development of new varieties.

  • This paper reviews the results of a series of efforts to develop structure-activity models for slow-reacting chemicals and olefins whose toxicity may be enhanced by the ultraviolet radiation. Photoinduced toxicity of 14 compounds was found to be a different result of competing factors of structure, having carbon-carbon double bonds. To mimic the biological consequences of photooxidative damage in mammalian cells, the photochemical mutagenicith of 14 chemicals was tested in the CAS. Simple olefins were photochemically mutagenic or carcinogenic with irradiation, increasing the alkylating activity from zero level to 0.87(abs/gram) for styrene, 0.25 for 1-butene, 0.11 for 1-hexene, respectively, whereas no photochemical mutagenicity was observed with 1-octene in the absence of the CAS. Oxide compounds, however, showed a decreasing trend of photoalkylating activities in the presence or absence of the CAS. We found that the structure-activity relationship was not applicable to our data.

  • The objectives of this study were to identify current problems and to propose alternatives of woodworking education in school. This study was carried out through the literature review. Even though woodworking in school has a lot of merits, it has not been fully established yet. Current problems in school woodworking were identified as the absence of educational philosophy of woodworking, unambiguous education objectives, incongruity of educational contents and hierarchy, inadequate quality of teachers, poor surroundings for practice, lack of ancillary materials for teaching and learning, and the absence of community for interchanging information. It was proposed that educational philosophy of woodworking and concrete education objectives should be set up, educational contents should be organized in a proper level, and surroundings for practice should be improved. And, it was also proposed that teacher education should be made to upgrade qualities of teachers, ancillary materials for teaching and learning should be developed, and community for interchanging information should be set up.

  • A low-temperature dyeing system for silk fabrics based on a redox system has been investigated. Some factors affecting dyeing of silk fabrics with levelling acid dyes in the absence and presence of certain redox system were investigated under different conditions. The variables studied were; type and concentration of redox system, dyeing conditions, i. e. temperature and time, dye concentration, material-to-liquor ration(LR) and colour fastness. The colour strength(K/S value) is outstandingly higher in the presence than in the absence of redox system. A comparison between the colour strength values of such dyeings abtained the three redox system would call for the following order ; Glyoxal/hydrogen peroxide>thiourea/hydrogen peroxide>glucose/hydrgen peroxide> nothing. In the presence of redox system, free radicals are supposed to be formed in both the fiber and the dye and the interaction between these free radicals bring about covalent fixation beside the usual electrostatic bonds, hydrogen bonds and Van der Waals forces.
