  • To obtain the basic information for agricultural utilization of germanium (Ge), the growth characteristics and Ge absorption in rice plant were investigated under different Ge concentrations by foliar spray application. The Ge concentrations were treated with 0 (control), 10, 20, 40 and $80mg\;L^{-1}$ in pot (1 5000$^{-1}$ a), respectively. The Ge absorption rate in rice by foliar spray application with $80mg\;L^{-1}$ in pot was higher in the order of leaf (5.75%) > stem (4.52%) > root (<0.01%). By foliar spray application, the Ge content in rice was higher in the order of $80mg\;L^{-1}$ > $40mg\;L^{-1}$ > $20mg\;L^{-1}$ > $10mg\;L^{-1}$. When rice was treated with $80mg\;L^{-1}$ of Ge, the Ge content in rice grain was higher in the order of rice bran ($0.21mg\;pot^{-1}$) $\gg$ brown rice ($0.04mg\;pot^{-1}$) ${\geq}$ polished rice ($0.03mg\;pot^{-1}$). By foliar spray application, the Ge uptake in rice bran was higher than that in other parts. Therefore, optimum Ge concentration by foliar spray application was $80mg\;L^{-1}$ in pot based on the results from the Ge treatments.

  • Effects of antioxidant compounds and antioxidant activities of proso millet cultivated in different areas were determined. The cultivated areas were Milyang (plain area of interior), Wonju (mountainous territory) and Sinan (coastal area), and cultivated varieties were Hwanggeumgijang (HGG), Byeoruk-gijang (BRG), Norangchal-gijang (NRG), Bulgeun-gijang (BGG), Whin-gijang (WG). The highest total polyphenol contents of methanolic extracts were 2.54 and 2.65 mg/g in BGG and BRG produced in Sinan, respectively. The highest total flavonoid content were 2.66 and 2.59 mg/g in BGG and BRG produced in Sinan, respectively. The highest total tannin contents were 1.87 and 1.42 mg/g in BRG and NRG produced in Sinan. The DPPH radical-scavenging activity was the highest value of BGG (8.54 mg TE/g) and BRG (8.53 mg TE/g) produced in Sinan. The ABTS radical-scavenging activity was the highest value of BGG and BRG of 19.48 and 19.29 mg TE/g in the grains produced in Sinan, respectively. Generally, there was difference in antioxidant compound contents on the methanolic extracts of proso millet between the cultivated areas and varieties.

  • The effects of cytochalasin B was studied for the cleavage and development of in vitro matured porcine follicular oocytes. The follicular oocytes were collected from slaughtered pig ovaries and matured for 65 hours. The matured oocytes were activated by 7% ethanol(v/v) in DPBS and the activated oocytes were subjected to cytochalasin B concentrations of 2.5, 5.0 and $7.5\;{\mu}g/mL$ for 3, 5 and 7 hours, and then the treated oocytes were cultured in NCSU23 with 0.4% BSA for 7 days. The cleavage rates were not different significantly in each treatment. However, the oocytes treated with $5.0\;{\mu}g/mL$ for 5 hours yielded a significantly higher morula rate(19.7%) than oocytes treated with $2.5\;{\mu}g/mL$ for 3 and 5 hours(9.4%). The sum rate of $2.5\;{\mu}g/mL$ concentration(10.5%) by hour was also significantly lower than those of 5.0(18.0%) and $7.5\;{\mu}g/mL$ concentration(14.6%). The blastocyst rate in oocytes treated with $5.0\;{\mu}g/mL$ for 3(9.4%) and 5 hours(9.0%) was significantly higher than the rate in oocytes treated with $2.5\;{\mu}g/mL$ for 3 hours(0%). The sum rate of $5.0\;{\mu}g/mL$ concentration also significantly higher than those of 2.5 and $7.5\;{\mu}g/mL$ concentration. The results demonstrated that the treatment of oocytes with cytochalasin B of $5.0\;{\mu}g/mL$ for $3{\sim}5$ hours was the optimal concentration and duration for parthenogenetic activation and blastocyst formation of in vitro matured porcine oocytes.

  • It was recently reported that nesfatin-1/NUCB2, which is secreted from the brain, controls appetite and energy metabolism. The purpose of this research was to confirm whether or not the protein and its binding site should have been expressed in the mouse reproductive organs and to know the possible effects of nesfatin-1 on the reproductive function. Using the ICR female mouse ovary and uterus, the expression of NUCB2 mRNA was confirmed with the conventional PCR and the relative amount of NUCB2 mRNA in the tissues was analyzed with real-time PCR. Immunohistochemical staining was performed using the nesfatin-1 antibody to investigate the nesfatin-1 protein expression and the biotin conjugated nesfatin-1 to confirm the binding site for nesfatin-1 in the ovary. Furthermore, in order to examine if the expression of NUCB2 mRNA in the ovary and uterus is affected by gonadotropin, its mRNA expression was analyzed after PMSG administration into mice. As a result, the expression level of NUCB2 mRNA in the ovary and the uterus was as much as the expression level in hypothalamus. As a result of the immunohistochemical staining, nesfatin-1 proteins were localized at the theca cells, the interstitial cells, and some of the luteal cells. However, the granulosa cells in the follicles did not stain. Interestingly, the oocytes in the some follicles were stained with nesfatin-1. On the other hand, nesfatin-1 protein binding sites were displayed at the theca cells and the interstitial cells near the tunica albuginea. After PMSG administration the expression level of NUCB2 mRNA was increased in the ovary and the uterus. These results demonstrate that for the first time the nesfatin-1 and its binding site were expressed in the ovary and NUCB2 mRNA expression was controlled by gonadotropin, suggesting an important role in the reproductive organs as a local regulator. Therefore, further study is needed to elucidate the functions of nesfatin-1 on the reproductive organs.

  • Is a failed blockbuster film? Is there no room for reconsideration of the value of the film in terms of its contents and forms? The purpose of this study is to answer these questions. In 2007, SHIM Hyung-rae's was in the limelight due to the nationalist discourse around the film rather than evaluation of the film itself. In terms of its narrative and formal properties, the film showed the difference from the Korean nationalist blockbuster films. It led to the disaccord and hard-to-understand results of having somewhat disappointed box-office success of 8,500,000 audiences in comparison to the input, of receiving well by a generous part of the audiences absorbed by nationalism, and of getting the critics' cynic criticism of the film's cinematic value. Eventually only provided the cultural battlefield of nationalism, was left as an unnoticed film in the realm of industry and criticism. However, it was interesting that there was a common ground between the film's supporters and the cynic critics. Both sides were being acknowledged that the spectacle of was way out of proportion to the degree that the spectacle was unbalanced with the story unfolding, achieved more than expected. Its spectacle overwhelming the narrative enfever a few audiences, and at the same time, it provided some reasons making critics face away from the film. In this context, the purpose of this study is to examine 's aesthetics that 'the spectacle dominating narrative' or 'the narrative as a pretext for showing spectacle,' leading to discussion of artistic/theoretical/critical value and to find out cinematic value of the film being regarded as a failure. In addition, this study is significant in that it suggests that is a new kind of moving image that it cannot be analyzed with existed critical methods of narrative film criticism; as a result, this study provides the chance to be evaluated through a new conceptual frame of the film. In order to grasp the narratological aesthetics, this study focuses on the concept of trickality that Andre Gaudreault suggests, and Tom Gunning's 'the cinema of attractions,' referring to the spectacle-oriented narrativity or the mode of production displaying the spectacle more than the narrative.

  • Objectives : This study was undertaken to identify the clinical and psychological characteristics in patients of mental disability assessment following traumatic brain injury who had the finding with or without abnormal brain imaging study. Methods : A consecutive series of 59 patients were assessed in hospital from January 1994 to December 1998. Patients were divided into 2 groups based on normal or abnormal brain imaging and the two groups were compared in demographic characteristics, psychiatric symptoms, type of head injury, clinical psychological findings. There were 27 patients with abnormal findings and 32 with normal findings in brain imaging study. Results : Abnormal finding group in brain imaging study had significantly higher incidence of psychosis, decreased memory, decreased appetite, increased nihilistic idea, and intracranial hemorrhage. Also, abnormal finding group showed significantly lower level of performance on the block design subtest of K-WAIS and had significantly lower scores on F, hypochodriasis, depression, hysteria, psychopathic deviate, psychasthenia and schizophrenia subscale of the MMPI. Conclusion : The findings suggest that the patients undergone brain surgery due to intracranial hemorrage at that time of brain injury may have higher frequency of abnormal findings in brain imaging study, complain more cognitive and affective symptoms, and have lower the abstract concept formation and perceptual organization abilities.

  • This study was conducted to investigate factors related to experience rate of low back pain(LBP) in the high school students, a questionnaire survey was carried out for 778 high school students in Andong city Kyungsang Pook province from 28th June to 10th July, 1993. The results were as follows: The experience rate of LBP for 778 high school students who were interviewed was 27.1 %. Unknown(47.4 %) was the highest in the cause of LBP. The experience rate of a academical high school students (57.8 %) was higher than the technical high school students(42.7 %) in association according to LBP and school division(P = 0. 001). The experience rate of 18 years old above students (60.2 %) was higher than 17 years old below school students(39.8 %%) in association between LBP and age(P = 0.031). The experience rate of students who go to bed at the hot floored bed (80.1 %) was higher than students who go to bed at the bed room (11.8 %) in association between LBP and room type(P = 0.012). The statisticaly significant variables related to LBP were school division, age and stress. It was revealed by this survey that independent variables related to LBP experience rate of high school students were important health problem. So the prospective research is need by those variables.

  • The objective of this study was to examine effect of ethylene glycol for semen cryopreservation in Korean Jeju Black Bull. The semen was cryopreserved with extenders containing cryoprotectants (7% glycerol and 3%, 5%, 7% ethylene glycol) and packed to 0.5 ml straws. The semen straws were located above 3 cm of liquid nitrogen for 5 min, 5 cm for 10 min and 8 cm for 10 min. And then frozen straw was plunged into $LN_2$. Post-thawed sperm motility, viability and membrane integrity were significantly higher in 5% ethylene glycol ($72.5{\pm}5.00%$, $54.88{\pm}0.66%$ and $46.00{\pm}2.40%$; p<0.05). Motility and viability were similar between 7% glycerol and 5% ethylene glycol. However, the membrane integrity was significantly higher in 5% ethylene glycol ($34.69{\pm}4.64%$ vs $46.00{\pm}2.40%$; p<0.05). The viability and membrane integrity were significantly higher in 5 cm for 10 min and 8 cm for 10 min than 3 cm for 5 min (viability: $55.81{\pm}2.94$, $55.19{\pm}3.34$ vs $47.94{\pm}3.48%$; p<0.05 and membrane integrity: $44.94{\pm}3.51$, $46.06{\pm}2.25$ vs $40.38{\pm}1.03%$; p<0.05). The percentage of capacitated sperm assessed by CTC staining, percentage of F pattern was higher in 7% glycerol, 5% and 7% ethylene glycerol, and AR pattern was significantly higher in 3% ethylene glycol. F pattern was significantly increased in 5 cm for 10 min and 8 cm for 10 min (p<0.05), but AR pattern was significantly increased in 3 cm for 5 min (p<0.05).

  • The aim of this study was to evaluate the effect of ${\alpha}$-tocopherol on blastocysts development and subsequent cryosurvival of the vitrification. The ${\alpha}$-tocopherol(0, 100, 200, 400 ${\mu}M$) was added in to culture medium for the bovine embryos. The blasocysts from the ${\alpha}$-tocopherol and untreated control groups were then frozen-thawed, and their cryosurvival was assessed by in vitro culture for 48 h. There were no differences in the overall cleavage rate($56.14{\pm}4.66$, $58.18{\pm}4.70$, $62.97{\pm}6.86$ and $51.17{\pm}7.28$) among four treatment groups. However, in blastocyst development and total cell number were significantly higher in ${\alpha}$-tocopherol 200 ${\mu}M$ ($38.60{\pm}7.12$; $106.33{\pm}3.50$) to culture medium than other treatment groups($29.30{\pm}5.24$, $31.60{\pm}7.12$ and $26.37{\pm}4.18$; $101.36{\pm}5.12$, $97.27{\pm}2.87$, and $91.23{\pm}7.52$ respectively). Before and after vitrification, the total cell number and blastocyst development of embryo were significantly higher in July to August than September to October. In conclusion, addition of ${\alpha}$-tocopherol 200 ${\mu}M$ to in vitro bovine embryo culture medium was beneficial for improving embryo quality by decreasing the embryo damage blsstocysts cell number and improving the tolerance of the embryos to cryopreservation.

  • This study was carried out to select the Eco-tree for successful phytoremediation of abandoned metalliferous mines. We examined vegetation and heavy metal concentrations of woody plants in abandoned mining areas, and also conducted seed germination and seedling growth experiment on contaminated soils from Gahak and Geumjeong mines. Pinus densiflora, Robinia pseudoacacia, Lespedeza bicolor and Alnus japonica showed high frequency in the survey areas and had high heavy metal concentrations compared to other species. Heavy metal concentrations were higher in roots than in leaves and stems. The seed germination rate was in the order of P. densiflora, L. bicolor, R. pseudoacacia, and Alnus japonica from the incubactor and greenhouse experiment. In the incubator experiment germination rate was highest in the control soil for P. densiflora and A. japonica. Germination rate of P. densiflora was highest on the 100% contaminated soil for Gahak mine while germination rate decreased with increased percentage of contaminated soil for Geumjeong mine. In the greenhouse experiment germination rate was lowest on the 40% contaminated soil for Gahak mine while germination rate was lowest on the 20% contaminated soil for Geumjeong mine and increased with increased percentage of contaminated soil. Shoot growth was highest for L. bicolor while root growth was highest for R. pseudoacacia except for 20% contaminated soil in Geumjeong mine.
