  • To investigate the possibility of improvement of seed mustard varieties, these experiments were conducted at Muan in Chonranamdo for three years with five local seed mustard varieties and seeding dates. Local varieties collected from Seoul, Cheju and introduced from Japan showed earlier bolting date while Yungsanpo and Suweon varieties bolted later and Suweon variety exhibited the latest maturity. Suweon variety had the shortest plant height with higher number of grains per pod. Seoul and Yungsanpo varieties had more total branch numbers than others. There was no varietal difference in grain weight, pod length and one liter weight. Grain yield per 10a was highest in Seoul variety by 247.5kg. Late seeding date delayed the bolting and flowering date while plant height, total branch numbers, pod numbers per ear and grain number per pod were decreased. The magnitude of varietal response to seeding date was varied greatly with traits. Grain weights per liter, 1,000 grain weight, pod lengths, oil contents, and fatty acid compositions were not affected by the different seeding dates.

  • This study was carried out to evaluate major agronomical characterization and phenol compound contents, Xanthine oxidase inhibitory activity (XO), Catalase activity, Superoxide dismutase activity (SOD) and 1,1-Diphenyl-2-picryl-hydrazyl (DPPH) radical sacvenging activity were analyzed in colored waxy corns. The mean of stem height and ear length were 248.8 cm and 18.6 cm, respectively. The pericarp thickness in CNU108 $(30.3{\mu}m)$ was thinner than other hybrids. The period of tasseling days in CNU69 and CNU202 were very shorter than other hybrids (59 days). 100-kernel weight of CNU50 was 35.6 g and heavier than the others. The antioxidant activities such as xanthin oxidase (XO), catalase and superoxide dismutase (SOD) were higher in CNU70 and CNUI 38. Especially highest EDA (electron donating ability) in DPPH radical scavenging effect was 94.8% and 94.6% in CNU160 and CNU193, respectively. In the results, the antioxidant enzyme activity and antioxidant acticity were higher in CNU109 and CNU 34 hybrids. The hybrids, CNU34, CNU70, CNU108, CNU 138 and CNU193 may be considered higher functional color waxy corn.

  • In this study, we sought to evaluate the growth characteristics and seed productivities of domestic tall fescue that were cultivated with differing combinations of drill widths and nitrogen-application rates in early spring; the examination was conducted at the National Institute of Animal Science, RDA, from 2013 to 2014. The main plots were three widths of 15 cm, 30 cm, and 45 cm, and the subplots were subject to nitrogen-application rates in early spring of 45 kg/ha, 90 kg/ha, 135 kg/ha, and 180 kg/ha. The growth and development characteristics did not vary by treatment in terms of drill width and early-spring nitrogen application. Tall fescue Purumi showed a stable seed productivity of two tons or greater when the drill width was set at 15 cm and 90 kg/ha of nitrogen was applied in early spring. The narrower the drill width, the greater the numbers of both the ears and seeds, while the length of the ear was longer when the drill width was wider. Regarding the influence of the drill width and early-spring nitrogen application on the productivity of seed-producing straw, the dry matter productivity was higher when the drill width was narrower; however, no particular trend was observed with respect to different amounts of fertilizer. The average production amount of the first round of straw after seed gathering was 6,920 kg/ha. The second round produced an average 8,134 kg/ha of dry matter.

  • This study is to investigate the status and problems in the anual physical examination in elementary & secondary schools. The study helps the introduction of health assessment. Two hundreds and forty nurse teachers of elementary & seconcary school in Seoul received in-service traomong fpr 20 daus frp, September 7 to September 27, 1992. Questionnaires were given to the 240 teachers and the number of collected questionnaire is 112. The result of the questionnaire analysis is like the following. First, the answered teachers aged 35~39, 36.6%; experience 6~10 years 37.5%; the number of class 31~40, 28.6%. Among the answered of the school doctors is practicioners. The doctors major subjects are 26.8% of internal medicine and 35.7% of surgery. Second, in elementary & secondary school nurse teachers received in-service training for the primary health assessment. And then 37.5% of schools practiced the health assessment. The term of the health assessment is largely a-year-length, occurately its rate of schools have practiced the assessment reaches 81.0%. The number of health assessment are consist of eyes, nose, ear, throat, skin, spine, heart and other abnormal regions and diseases all over the body. And 83.3% of the rate of the health assessment includes all these contents. The period of the health assessment is 7 to 28 days. Third, the physical examination conducted by school doctors is 91.0%. The method is various; one is 56.6% of the students who checked first by he nurse teacher. The number of 15.1% of the schools is directly checked by the school doctor. The invited medical doctors are divided into two categories. The number of general physician is 61.9%. Contrary to that school doctors are 38.1%. The contents of the medical examination is all the items printed on the medical examination sheet. To follow the medical examination sheet the number of school is 59.6%. Eyes, throat, skin and heart etc. partly medical examination is 40.4%. The rate of schools that used only stethoscope, tongue pressor as the medical instruments reaches 53.4% and 87.1% of elementary & secondary school give the invited doctors the allowance a nurse teachers conference decided. The number of 8.9% schools pay the doctors independent allowance. The medical examomatopm allowance is 200 to 250 won per capita. The rate is 56.1%. Forth, after the medical examination 72.1% of school sends letter to the parents to notice the result of the examination. The number of response from parent is 12.5%. The observation record in secondary school is 70.6% for junior, and 80.0% for senior respectively, and 65.5% is for the elementary school children. To conclude the regular physical examination in elementary & secondary school is very important. Because the students are in the stage of rapid growth and development.

  • Using Digital Imaging and Communications in Medicine(DICOM) and a 3D medical imaging program, the characteristics of the external auditory canal(EAC) were compared. Using images of the ears of 63 different male and female subjects of varying age, this study measured and compared EAC transverse axis lengths, internal diameter circumferences, and upper and lower curvature angles. The findings of the study indicated differences in EAC shapes according not only to age and sex but also to the left and right of the same subject. A comparison between the sexes of the subjects (35 males and 28 females) indicated that, on average, the length of the EAC was 4.75mm longer in males. Based on the lower curvature angle, the interior side of the diameter circumference of the EAC was found to be reduced on average by 37.2% compared to the exterior side. Although the upper curvature angle was on average $25.7^{\circ}$ larger than the lower curvature angle, 4 subjects showed a larger lower curvature angle and large differences between the upper and lower curvature angles were observed in 8 subjects of the younger age group (4~14 years old). This indicated changes in EAC curvature shapes during growth. This study presents a method to raise safety and precision by comparing direct measurements taken through physical means and indirect measurements acquired from existing ear samples. This was possible due to technological developments in which 3D medical image representation technology creates images close to reality, and, through further development, this method is expected to be used for standardization research of EAC shapes.

  • The objectives of the present study were to initiate cloning of Korean native goat by somatic cell nuclear transfer (NT) and to examine whether unovulated (follicular) oocytes can support the same developmental ability of NT embryos as ovulated (oviductal) oocytes after hCG injection in stimulated cycles of the goat. The in vivo-matured and immature oocytes were collected from the oviducts and follicles of superovulated does, respectively, and the immature oocytes were maturated in vitro. Ear skin fibroblasts derived from a 3-yr-old female Korean native goat were used as the donors of nuclei or karyoplasts. Following fusion, activation and in vitro culture to a 2- to 4-cell stage, 49 in vitro-derived and 105 in vivo-derived embryos were transferred to 6 and 17 recipient does, respectively. One doe and three does of the respective groups were identified as pregnant by ultrasonography on day 30 after embryo transfer. However, only one doe, which had received in vivo-derived embryos, delivered a normal female kid of 1.9 kg on d 149. The cloned kid gained more weight than her age-matched females as much as 87% during the first 4 mo after birth (17.7 vs. $9.4{\pm}0.8$ kg) and reached puberty at 6-mo age a few months earlier than normal female does. The telomere length of the kid, which was similar to that of the donor fibroblast at 2-mo age, decreased 8% between 2- and 7-mo ages. Moreover, at 7-mo age, she had 21% shorter telomere than her age-matched goats. To our knowledge, this is the first case in which a cloned animal born with a normal weight exhibited accelerated growth and development. The unusually rapid growth and development of the cloned goat may have resulted from SCNT-associated epigenetic reprogramming involving telomere shortening.

  • This study was canted out to develop cell lines overexpressing human H-transferase (HT). One of the approaches to prevent hyperacute rejection in xenotransplantation might be the expression of human HT in porcine cells. In this study, we cloned human HT gene from HepG2 cells using RT-PCR to establish HT-overexpressing vector. The full-length cDNA of human HT was inserted into the 3' end of CMV promoter for construction of the overexpression vector pRc/CMV-hHT. Using ietPEI DNA transfection reagent, the vector was introduced into porcine ear skin fibroblasts from newborn piglets. Transfected cells were selected by treatment of $300{\mu}g/ml$ G418 for 12 days. After antibiotic selection, survived colonies with approximately 5mm in diameter were picked and analysed for transgene human HT by PCR. The colonies proven to be human HT transfectants were analysed by RT-PCR to determine their expressions or human HT. In all colonies tested, human HT mRNA was detected. This result demonstrates the establishment of porcine cell lines overexpressing human HT, and these cell lines may be used for the development of transgenic pigs for xenotransplantation.

  • The effect of Bu-Zhong-Yi-Qi-Tang (BZYQT) on the changes of ultraviolet (UV) light B radiation-induced apoptotic sunburn cell (SBC) and epidermal ATPase-positive dendritic cell (DC) in SKH1- hr or ICR mouse were investigated. The mice were treated with UVB (200 mJ/$cm^2$) and were sacrificed 24 h later. BZYQT (50 mg/kg of body weight) or vehicle (saline) was given i.p. at 36 and 12 h before irradiation, and 30 min after irradiation or BZYQT cream (0.2%) or cream base (vehicle) was topically treated at 24 h and 15 min before irradiation, and immediately after irradiation. The skin of SKH1-hr mouse prepared from the back of untreated mice exhibited about 0.3 SBC/cm length of epidermis, and 24 h after UV irradiation, the applied areas show an increased number of SBCs. But the frequency of UVB-induced SBC formation was reduced by intraperitoneal injection of BZYQT extract (p < 0.01). The numbers of DC in normal ICR mouse were 628.00 ${\pm}$ 51.56 or 663.20 ${\pm}$ 62.58 per $mm^2$ of ear epidermis. By 1 day after UVB treatment, the number of ATPase-positive cells/$mm^2$ were decreased by 39.0% or 27.1% in i.p. or topical application group with vehicle. Treatment of BZYQT was associated with increase of 33.9% in i.p. group (p < 0.05) or 2.7% in topical application group in the number of ATPase positive cells compared with the irradiation control group. The results presented herein that BZYQT administration could reduce the extent of skin damages produced by UVB.
