  • Historically, LCD monitors have not been able to be used for frame-sequential stereoscopic 3D visualisation due to their slow pixel response rate. With LCD pixel response rates now in the single-digit millisecond range it is natural to ask whether it is now possible to achieve frame-sequential stereoscopic 3D viewing on LCDs.

  • Objective: To investigate the electronic anti-nausea instrument (EANI) combined with hydrochloride palonosetron for prevention of chemotherapy-induced nausea and vomiting following highly emetogenic chemotherapy. Methods: Patients who received highly emetogenic chemotherapy were randomly assigned to a treatment group (60 patients) treated with EANI combined with hydrochloride palonosetron, and control group (also 60 patients) given only hydrochloride palonosetron. Chemotherapy related nausea and vomiting were observed and recorded in both groups of patients from the start till the end of chemotherapy. Results: Complete control rates of vomiting in treatment and control group were 40%, and 35%, respectively, without any statistical ly significant difference (p>0.05); however the response rates are 95.0%, 78.3%, respectively, with statistical difference (p<0.05). Complete control rates of nausea in treatment and control group were 36.7%, 30%, respectively, without statistical difference (p>0.05); but the response rates are 90.0%, 76.7%, respectively, with statistical difference (p<0.05). Conclusion: EANI combined with hydrochloride palonosetron for prevention of nausea and vomiting induced by chemotherapy could be more effective than hydrochloride palonosetron alone, and can be recommended for use in prevention and treatment of chemotherapy-induced nausea and vomiting following highly emetogenic chemotherapy.

  • 물에 녹지 않는 폴리(페녹시-메틸아미노)포스파젠을 합성하여 혈당 측정을 위한 새로운 형태의 진단막으로서의 가능성을 조사하였다. 혈액속의 글루코우즈의 농도를 변화시켜가며 활성화된 폴리포스파젠 진단막을 가지고 680 nm에서의 최종흡광도를 측정하였다. 시간에 따라 변화하는 흡광도의 값(K/S)을 이용해 글루코우즈의 농도를 얻었다. 친수성인 메틸아미노기와 소수성인 페녹시기의 치환율이 글루코우즈의 농도 측정에 미치는 영향을 조사하였다. 친수성기의 치환율이 증가함에 따라 글루코우즈의 농도와 K/S와의 기울기 값(Dose-Response Slope : DRS)이 점차적으로 증가하였다. 그러나 친수성기의 치환율이 5% 이하일 때는 DRS가 너무 낮았고 친수성기의 치환율이 25% 이상일 경우에는 DRS가 급격히 증가하여 정확한 글루코우즈의 농도측정이 어려웠다.

  • Response of grain yield and milled-rice protein content to nitrogen topdress (N) timing at panicle initiation stage (PIS) is critical for quantifying real-time N requirement for target grain yield and milled-rice protein content. Two split-split-plot experiments with three replications, one in 2004 and the other in 2005, were conducted in Experimental Farm, Seoul National University, Suwon, Korea. The experiments included three N rates at tillering stage (TS), three N timing treatments at panicle initiation stage (PIS) and two rice cultivars. The N rates at TS, N timing at PIS, and rice cultivars were randomly assigned to main plot, sub plot, and sub-sub plot, respectively. Results showed that the delayed N application at PIS reduced grain yield in 2004 and increased milled-rice protein content in both years significantly at 0.05 probability level. The calculated optimum N timing at PIS from pooled data by N rates and rice cultivars in two years was at 28 days before heading (DBH). However, real-time of N timing at PIS was dependent on plant growth and N status around PIS that in turn was dependent on applied N rates at TS. The optimum N timing at PIS was at 30 DBH for no N treatments at TS while at 27 DBH for 3.6 and 7.2 kg N/10a treatments and at 27 and 29 DBH for Hwaseongbyeo and Daeanbyeo, respectively. In general, earlier applied N at PIS resulted in lower milled-rice protein content but the highest grain yield was expected to be obtained when N topdress at PIS was applied at the time when shoot N concentration started to drop below about 23 mg/g due to dilution effect after transplanting. In conclusion, the results of our experiments imply that the currently recommended N topdress time (24DBH) at PIS in Korea should be reconsidered for the higher grain yield and the better quality of rice.

  • 벼 생력 직파재배양식으로 최근에 개발 보급된 무논골뿌림재배의 파종 피술체계확립의 일환으로 파종량에 따른 생육 및 수량반응을 검토하고자 시험을 실시하였던바, 그 결과를 요약하면 다음과 같다. 1. 파종량이 증가할수록 $m^2$당 입모수는 직선적으로 증가하였으나, 개체당 수수는 입모수 증가에 따라 완만하게 감소하는 경향이었다. 2. 유효경 비율 및 출수기 경당엽면적은 파종량이 증가함에따라 감소하였으며 출수기는 큰차이가 없었다. 3. 도복관련 형질중 간장, 수장, 좌절량, 줄기굵기 등이 파종량 증가와 함께 감소하는 경향이었고, 10a당 7kg이상에서는 포장도복이 심하게 발생되었다. 4. $m^2$당의 수수증가에 따라 수당립수와 등숙비율이 감소하였으며, 수량은 10a당 5kg을 기점으로하여 점차 감소하는 경향이었다. 5. 수량에 대한 수량구성요소의 경로계수 분석결과에 의하면 등숙비율의 직접효리가 가장컸으며, 최대수량을 얻기위한 $m^2$당 입모수는 105개 정도, 이때의 10a당 파종량은 4.5kg 수준이었다.

  • A selection experiment with Romney Marsh sheep was used to evaluate direct responses to selection. Two flocks were maintained; a) the selection line formed in 1979 by the Romney Group Breeders to select for high prolificacy, defined as the number of live lambs born per ewe joined per year and b) a control line, established in 1982, where flock replacements were chosen at random. Predicted responses per year of birth female group and per year respectively were 0.033 and 0.027 live lambs. The rate of predicted response per year was within the theoretical expected range from 0.01 to 0.03 of the mean. The rates of realized response in prolificacy per year of birth female group and per year respectively were 0.026 and 0.021. These estimates of realized responses represented between 0.01 and 0.02 of the control line mean per year.

  • Acoustic pressure response and NO formation of hydrogen-air diffusion flames at various pressures are numerically studied by employing counterflow diffusion flame as a model flame let in turbulent flames in combustion chambers. The numerical results show that extinction strain rate increases linearly with pressure and then decreases, and increases again at high pressures. Thus, flames are classified into three pressure regimes. Such non-monotonic behavior is caused by the change in chemical kinetic behavior as pressure rises. Acoustic pressure response in each regime is investigated based on the Rayleigh criterion. At low pressures, pressure-rise causes the increase in flame temperature and chain branching/recombination reaction rates, resulting in increased heat release. Therefore, amplification in pressure oscillation is predicted. Similar phenomena are predicted at high pressures. At moderate pressures, weak amplification is predicted. Emission index of NO shows similar behaviors as to the peak-temperature variation with pressure.

  • The present study was undertaken in an effort to investigate the effects of alcohol on survival of mice and on their humoral and cellular immune responses, The immune responses examined were Arthus and delayed-type hyperrsnesitivity(DTH) reactions to sheep red blood cells(SRBC), contact hypersensitivity to dinitrofluorobenzend(DNFB), antibody response to thymus - dependent SRBC and to thymus -independent polyvinylpyroridone(PVP), and the recovery of Crytococcus neoformans from the liver, spleen, kidney and brain of experimentally infected mice. The administration of ethanol concentrations of 20% or less did not cause any change in survival rates as compared withs saline injected control group. In general, ethanol administration inhibited the Arthus and DTH reactions to SRBC, contact hypersensitivity to DNFB, and antibody response to both SRBC and PVP and it also decreased the resistance of mice to C. neoformans infection. Taken together, the present study stongly suggested that ethanol inhibits immune response and decrease the resistance of mice to C. neoformans infection.

  • Breast cancer is the most common cancer in Jamaican women. Locally advanced breast cancer (LABC) is associated with aggressive biology and poor prognosis, and has a predilection for African-American women. In this retrospective review, we assessed the prevalence of LABC as a breast cancer presentation in a population of mainly Afro-centric ethnicity, and determined disease characteristics and response to pre-operative chemotherapy. LABC was prevalent (20%), and had a low pathological response rate to pre-operative chemotherapy, with a high risk of disease recurrence. Increased utilization of breast cancer screening may help detect cancer at less advanced stages, and optimizing pre-operative chemotherapy is recommended to improve response rates and ultimately survival.

  • Nonclassically damping domes from drastic variations of energy absorption rates of the materials in different parts of structures, or from the external damping sources inserted into the structures. In this study, an approximate method to calculate the frequency response of a method is superior to other approaches in respect of computational effort and accuracy. In addition, when frequency response is calculated by neglecting the off-diagonal elements of modal damping matrix, a criterion to ensure small errors is derived. In is shown that the criterion can be described as the vector sum of each modal coupling to the corresponding mode.
