  • This research intended to investigate, from an ecological perspective, significant predictors affecting school life satisfaction. The subjects were 312 students(2nd grade) of commercial high school in Kyonggido. Data collected by questionnaire survey were analyzed by SPSS Win 22.0 and descriptive statistics, correlation analysis, hierarchical linear regression, and stepwise regression were conducted. There were 21 independent variables: 8 organism variables (self-competence, interpersonal skills, internal control, mood awareness, emotional expression, empathy, emotional regulation, emotional capability), 9 microsystem variables(school variables: the relationship with teachers, school learning, classroom climate, school welfare facilities, school environment/peer variables: peer relationship/family variables: family functioning, education level of fathers, economic status), 2 mesosystem variables(parent-teacher relationship, parent-children's peer relationship), 1 exosystem variables(satisfaction with Korean educational system), 1 macrosystem variables(Korean's primal belief in educational achievement). The results are as follows; the significant variables were the relationship with teachers, satisfaction with Korean educational system, peer relationship, emotional capability, parent-teacher relationship($R^2=45.3%$); and the effect of microsystem was the strongest($R^2=35.7%$). This research is meaningful of analyzing school life satisfaction of commercial high school in terms of ecological perspective.

  • The effects of volatile flavor extracts of eight different herbal medicines, Juniperus rigida (JR), Saussurea lappa SL), Cnidium officinale (CO), Angelica gigas (AG), Eugenia caryophyllata (EC), Angelica tenuissima (AT), Mentha arvense (MA), and Artemisiae argyi (AA), were investigated on LPS-stimulated inflammation using Raw 264.7 cells. The volatile flavor extracts of CO and AG considerably inhibited LPS-stimulated NO, $PGE_2$, IL-6, and TNF-${\alpha}$ (except AG) production, as well as iNOS expression. Major volatile components of CO were identified as ligustilide and of ${\beta}$-eudesmol as AG by GC-MS analysis. Thus, these results suggest that the volatile extracts of CO and AG may be useful as potential therapeutic agents for inflammation-associated disorders.

  • Objective: The main objective of this study was to determine the effect of different diets for early-weaned (EW) calves on rumen development, and how this affects fat deposition in the longissimus dorsi of adult Korean Hanwoo beef cattle. Methods: Three EW groups were established (each n = 12) in which two- week-old Hanwoo calves were fed for ten weeks with milk replacer+concentrate (T1), milk replacer+concentrate+roughage (T2), or milk replacer+concentrate+30% starch (T3); a control group (n = 12) was weaned as normal. At six months, 5 calves of each group were slaughtered and their organs were assessed and rumen papillae growth rates were measured. The remaining calves (n = 7 in each group) were raised to 20 months for further analysis. Results: Twenty-month-old EW calves had a higher body weight (BW), backfat thickness (BF), longissimus dorsi muscle area (LMA) and intramuscular fat (IMF) than the control (p<0.05). Organ growth, rumen histology, and gene expression patterns in the 6-month-old calves were positively related to the development of marbling in the loin, as assessed by ultrasound analysis (p<0.05). In the group fed the starch-enriched diet (T3), higher BW, BF, LMA, and IMF were present. The IMF beef quality score of 20-month-old cattle was 1+ for the T2 and T3 diets and 1 for the T1 diet (p<0.05). Conclusion: Papillae development was significantly greater in calves fed on high-concentrate diets and this may have resulted in the improved beef quality in the EW dietary groups compared to the control.

  • There has been discussed very little about animation authorship studies, especially the themes of authors and their original animation texts since 1990s. This study is to explore the academic discourse of animation authorship studies understanding the media aesthetics of animation and the scholarly approach of animation studies about authorship. This article examines 55 articles via meta analysis about animation authorship studies drawn from the 1,516 articles on the general animation studies. The results were as follows. First, the domestic animation studies on the authorship were made about animators of Japan, US, and european countries. Second, It was dominant that scholarly interest on the screen direction and visual expression of animation texts. This shows the authorship approaches were mainly about visual aspects of animations. The domestic animation authorship studies did not trace the authorship issues on author's world view and visual style revealed in the corpus of texts. Instead, they discussed authorship issues on the characteristics of individual animation text. It has been evident that animation studies were not enthusiastic about building the independent theory on animation. Therefore, animation studies have tried theorizing the animation issues borrowing the literature and film theories. This study can contribute to increase phase of animation studies by drawing the intensive discussion of animation authors and their authorship.

  • During the recent epidemic period ($1995{\sim}1996$), seven strains of rubella virus were isolated in Korea. To analyze phylogenetic relationship between seven Korean strains and rubella virus strains from other different geographical areas, structural genes (E1, E2 and C) of Korean strains were enzymatically amplified and automatically sequenced. The sequence similarities of the E1, E2 and C genes of the cosmopolitan types were $95.8{\sim}98.1%$, $92.6{\sim}99.2%$ and $96.4{\sim}99.3%$ based on 1,441, 122 and 139 nucleotides and $96.9{\sim}98.5%$, $90{\sim}100%$ and $97.8{\sim}100%$ based on 480, 40 and 46 amino acids compared to the sequences of strain RA27/3, respectively. In contrast, the sequence similarities of the E1, E2 and C genes of the Asian types were $91.5{\sim}92.1%$, $83.6{\sim}88.5%$ and 91.4% based on nucleotides and $96.9{\sim}97.7%$, 85.5% and 97.8% based on amino acids compared to the sequences of strain RA27/3, respectively. However, immunodominent epitopes of the E1 gene of the cosmopolitan and Asian types were well conserved, and the growth patterns in cell culture and immunofluorescent antibody titers in cross-reaction test showed no differences between two different types. In phylogenetic analysis based on nucleotide sequences of each gene regions, the cosmopolitan and Asian types formed two distinct phylogenetic lineages. These data showed two distinct genotypes of rubella viruses cocirculated in Korea, but no significant differences in the antigenicity of two different rubella virus strains were found.

  • Lactoferrin is an iron-binding glycoprotein with many biological roles, including the protection against microbial and virus infection, stimulation of the immune system. We developed the transgenic Siberian ginseng (Acanthopanax senticosus) cell cultures producing the human lactoferrin (hLf) protein following Agrobacterium tumefaciens-mediated transformation. A construct containing a targeting signal peptide from tobacco endoplasmic reticulum fused to hLf cDNA under the control of an oxidative stress-inducible SWPA2 promoter was engineered. Transgenic Siberian ginseng cultured cells to produce a recombinant hLf protein were successfully generated and confirmed by PCR and Southern blot analysis. ELISA and western blot analysis showed that full length-hLf protein was synthesized in the transgenic cells. The production of hLf increased proportionally to cell growth and reached a maximal (up to 3% of total soluble proteins) at the stationary phase. These results suggest that the transgenic Siberian ginseng cultured cells in this study will be biotechnologically useful for the commercial production of medicinal plant cell cultures to produce hLf protein.

  • Ferritin is ubiquitous in bacteria, animals and plants. Ferritin is thought to play two main roles in living cells to provide iron for the synthesis of iron protein such as ferretoxin and cytochromes and to prevent damage from radicals produced by iron/dioxygen interaction. To enhance the resistance of potato to Erwinia carotovora, the soybean ferritin gene was introduced into the potato either under CaMV 35S or hsr203J promoter. Potato transgenic plants were screened by PCR analysis using specific primers to the ferritin gene. Expression of ferritin gene under CaMV 35S and hsr203J promoter in potato transgenic plants was confirmed by northern blot analysis. hsr203J promoter known to pathogen inducible in tobacco drives the induction upon Phytophthora infestan in potato and the transcript level of ferritin gene was extremely high after 24 hours post inoculation. One of transformants under CaMV 35S promoter was increased 2.5 fold than untransformant. Each one of transgenic potato containing gene promoter CaMV 35S and hsr203J-ferrtin fusion exhibited tolerance against potato soft rot.

  • A VP6 fragments was subcloned with BamHI in the binary pMBP-1 vector under Califlower Mosaic Virus (CaMV) 355 promoter and neomycin phosphotransferase II (npt II) gene. The recombinant binary vector was mobilized into Agrobacterium-tumefaciens LBA4404 by the freeze-thaw method and potato (Solanum tubensum L. cv Desiree) was transformed by modified leaf-disc cocultivation. Shoots were induced on MS medium with 0.01 mg/L NAA, 0.1 mg/L GA$_3$, 2.0 mg/L Zeatin, 100.0 mg/L kanamycin, 500.0 mg/L carbenicillin. In order to identify the copy number of VP6 into potato plant, total genomic DNA was isolated from transgenic potato and analysed by Southern blotting. Genomic DNA and total mRNA analysis demonstrated the incorporation of the foreign gene into the potato genome, as well as their transcription.
