The purpose of this study was to investigate the effects of an after-school cooking program on the eating habits and sociality of children. Thirty five children from the 3rd to the 6th grade of G Elementary School participated in this program comprising 12 periods of cooking activities, from May to August 2013. The content of the after-school cooking program included japchae, topokki, jajangmyeon, oi sobagi, cake, snack wrap, vegetable fried rice, sticky noodle, sushi, pizza, rice muffin, and sandwiches. Before and after learning, the participants' eating habits and sociality were investigated. The study analyzed the mean, standard deviation, and Wilcoxon Matched-Pairs Signed-Ranks Test results for a comparison between the pre- and post-test results. On the basis of the research findings and discussions, the study reached the following conclusions. First, the after-school cooking program was analyzed as being helpful and useful in categorizing the eating habits of children as sanitary dietary life, well-mannered dietary life, and healthy dietary life. Further, more girls than boys fostered effective eating habits. Second, the after-school cooking program was analyzed as being helpful and useful in determining sociality and more girls than boys fostered effective sociality. Third, cooking is an appropriate topic for the after-school program of Korean elementary schools, and the cooking program has expanded in G Elementary School after the abovementioned experiment.

본 연구는 옥살산으로 전처리를 수행한 후 얻어진 옥수숫대를 이용하여 동시당화발효를 위한 최적조건을 탐색하였다. Pichia stipitis CBS 6054를 이용한 동시당화발효에서 독립변수인 반응온도($25.8{\sim}34.2^{\circ}C$)와 교반속도(80~220 rpm)에 대한 에탄올 생산량은 각각 99% 신뢰구간을 가졌다. 종속변수로 에탄올 생산량을 적용하였을 때 $30^{\circ}C$, 170 rpm에서 최대의 에탄올 생산을 예측할 수 있었다(22.5 g/L). 최적의 온도 및 교반속도에서 최적 질소원을 조사한 결과 yeast extract (1.25 g/L)와 urea (1.25 g/L)를 혼합하여 사용하였을 경우 에탄올 생산량은 증가하였으며 trace metal 성분과 비타민은 첨가하지 않았을 때 에탄올 생산이 촉진되었다. 동시당화 발효를 위한 $KH_2PO_4$, $MgSO_4{\cdot}7H_2O$의 최적 농도는 각각 1 g/L, 0.25 g/L로 나타났다.

Terzaghi's theory of one-dimensional consolidation is restricted in its applicability to relatively thin layers and small incremental loading. Because it is assumed to infinitesimal strain and linear material function. For this reason, Gibson et al established a rigorous formulation for the one-dimensional nonlinear finite strain consolidation theory. There are some difficulties in the application of finite strain consolidation theory. The developed program consisted of several forms and modules. These forms and modules with graphic-user-interfaced format are used in analysis of consolidation practices. For the purpose of verification of developed program. the results of case study and prediction of developed program are compared. The results of comparison is fairly well with prediction and measured data. And with varying finite strain consolidation parameter, g(e) or λ(e), the sensitivity of predicted values were examined.

Numerical analysis using a three dimensional finite element program(ABAQUS) is a powerful method which can evaluate the soil-pile-structure interaction under the dynamic loading and reduce the computation time significantly, but has not be widely used because modeling a soil-pile system and setting the parameter for the entire model are difficult and a three dimensional finite element program is not user friendly. However, a three dimensional finite element program is expected to be widely used because of advance in research of modeling technique and development of the modeling and visualization. In this study, ABAQUS is used to simulate the 1g shaking table model pile test, and the numerical results are compared with the 1g shaking table test results. The application about the soil stiffness and boundary condition change is estimated and then parametric study for various input acceleration amplitudes, various input frequencies, and various surcharge is carried out.

KML001 reduced the proliferation of HCT116 cells in a concentration- and time-dependent manner without change of cell viability. Beclin-1 expression was significantly attenuated by KML001 (P<0.05), but no significant changes were observed in KML001-treated cells. The number of cells in G1 phase was increased 48 hr after KML001 treatment. Furthermore, a dramatic reduction in the frequency of beating and the number of embryoid bodies of the cells was noted after treatment. Taken together, KML001 suppresses the proliferation of HCT116 cells, which might be due to G1 phase arrest.

Maize is a socioeconomically important crop in many countries. Recently, a high incidence of stalk rot disease has been reported in several maize fields in Gangwon province. In this report, we show that maize stalk rot is associated with the fungal pathogens Fusarium subglutinans and F. temperatum. Since no fungicides are available to control these pathogens on maize plants, we selected six fungicides (tebuconazole, difenoconazole, fluquinconazole, azoxystrobin, prochloraz and kresoxim-methyl) and examined their effectiveness against the two pathogens. The in vitro antifungal effects of the six fungicides on mycelial growth and colony formation were investigated. Based on the inhibition of mycelial growth, the most toxic fungicide was tebuconazole with 50% effective concentrations ($EC_{50}$) of < $0.1{\mu}g/ml$ and $EC_{90}$ values of $0.9{\mu}g/ml$ for both pathogens, while the least toxic fungicide was azoxystrobin with $EC_{50}$ values of 0.7 and $0.5{\mu}g/ml$ for F. subglutinans and F. temperatum, respectively, and $EC_{90}$ values of > $3,000{\mu}g/ml$ for both pathogens. Based on the inhibition of colony formation by the two pathogens, kresoxim-methyl was the most toxic fungicide with complete inhibition of colony formation at concentrations of 0.1 and $0.01{\mu}g/ml$ for F. subglutinans and F. temperatum, respectively, whereas azoxystrobin was the least toxic fungicide with complete inhibition of colony formation at concentrations > $3,000{\mu}g/ml$ for both pathogens.

This study investigated whether presynchronization with GnRH 6 days before initiation of the Ovsynch program improved reproductive outcomes in dairy cows. Additionally, postponement of initiation of the Ovsynch program for cows during the metestrus phase by 5 days was investigated to determine if it improved reproductive outcomes. To accomplish this, 941 Holstein dairy cows with unknown estrous cycle were randomly allocated into an Ovsynch group (n = 768; $100{\mu}g$ gonadorelin [a GnRH analogue], $500{\mu}g$ of cloprostenol [$PGF_{2{\alpha}}$ analogue] seven days later, $100{\mu}g$ gonadorelin 56 h later and timed artificial insemination [AI] 16 h after) and a G6-Ovsynch (n = 173) that received $100{\mu}g$ GnRH followed by the Ovsynch program 6 days later. Additionally, 272 dairy cows with known estrous cycle (metestrus stage) received the Ovsynch 5 days later (Day 5-Ovsynch group, n = 272). The odds ratio (OR) for pregnancy was analyzed by logistic regression using the LOGISTIC procedure in SAS. The treatment group (p < 0.001) and AI season (p < 0.05) significantly affected the probability of pregnancy, whereas farm, cow parity, calving to AI interval, and body condition score had no affect (p > 0.05). The Day 5-Ovsynch group had a higher probability of pregnancy (OR: 1.71) than the Ovsynch group, while that of the G6-Ovsynch group was intermediate (p > 0.05). Cows inseminated during winter had a higher OR (1.39) than those inseminated during spring. Overall, additional GnRH treatment 6 days before the Ovsynch did not improve reproductive outcomes, whereas postponement of the initiation of Ovsynch by 5 days for cows during metestrus improved reproductive outcomes.
