Cold and Heat pattern identification(CHPI) in traditional East Asian medicine(TEAM) is one of the major indicator to distinguish characteristics of disease and to determine treatment method. Basic parameters to determine CHPI include the pulse rate, respiration rate, and pulse power. Studies to associate physiological responses of human body by cold stress(CS) with CHPI in TEAM were rarely done so far. This study aims to explore the effects of cold stress on pulse signal via a feasibility study for three subjects and investigate some indices which can reflect autonomic nerve reaction(ANR). We measured radial pulse signals and respiration signal of the investigated subjects before the CS, during the CS which continues for 5 minutes, and immediately after the CS, respectively. Finally, we analyzed the pulse rate (P), respiration rate (R), pulse power, pulse depth, and pulse rate per respiration (P/R ratio). As a result, the P/R ratio showed a consistently decreasing tendency through the CS stimulation process, while other parameters behaved more complex and in subject-specific ways. It implies that, among candidate parameters, the P/R ratio is a simple but the most probable parameter that can be used as the ANR indicator. This result is also consistent with the theory in TEAM scripts, in which the P/R ratio is predicted to be a direct indicator for the CHPI. This pilot study shows that P/R ratio can be more appropriately associated with the ANR than heart rate or respiration rate alone. Extensive studies will be necessary to verify or confirm the P/R ratio as an appropriate and well defined parameter for ANR.

Sixteen steers were used to investigate the efficacy of the sustained-release implant of bovine somatotropin (bST) in improving growth and feed:gain ratio during 12 weeks. Administration of the 400 mg bST implant resulted in a 16.1% increase in growth rate, and this increase was significant (p<.05). The use of the sustained-release implant did not alter (p>.05) feed intake and feed:gain ratio. Thirty-four cows were used to investigate the efficacy of the sustained-release implant of bST in milk production during 4 weeks. Administration of the 200 mg bST implant resulted in an 8.7% increase in milk production, and this increase was significant (p<.05). Twenty-four barrows were used to investigate the efficacy of the sustained-release implant of porcine somatotropin (pST) in improving growth, feed:gain ratio and backfat thickness during 6 weeks. Administration of the 120 mg pST implant resulted in a 11.4% increase in feed:gain ratio and a 60% decrease in backfat thickness, and these results were significant (p<.05). But the use of the sustained-release implant did not alter (p>.05) growth rate and feed intake.

본 연구는 실험실규모로 제작된 고속퇴비화기를 이용하여 음식물쓰레기를 퇴비화하고자 하였다. 연구의 주된 지표는 수분, 온도, C/N비였다. 수분을 조건으로한 실험에서 pH 변화는 60%가 가장 높았으며, 70%는 혐기성반응이 일어남을 볼 수 있었고 C/N비 변화에서는 $NH_3$의 다량발생으로 질소소실의 우려가 있는 것으로 드러났다. 온도를 조건으로 한 실험에서 $60^{\circ}C$의 pH가 가장 높았으며 $70^{\circ}C$의 pH는 토양의 pH 보다 낮게 나타나 지나친 고온은 퇴비화에 역효과를 나타냄을 볼 수 있었고, C/N비의 실험에서는 C/N비 25가 pH와 C/N비의 변화가 가장 작았다. 결과적으로 음식물쓰레기의 퇴비화에서 수분은 50~60%, 온도는 $60^{\circ}C$, C/N비는 25가 적당함을 알 수 있었으며, 조건을 잘 조절해 준다면 56시간안에 퇴비화가 가능할 것으로 판단된다.

Background and Aim: Selumetinib is a promising and interesting targeted therapy agent as it may reverse radioiodine uptake in patients with radioiodine-refractory differentiated thyroid cancer. We conduct this metaanalysis to compare the efficacy and safety of selumetinib with current therapies in patients with advanced cancer. Methods: An electronic search was conducted using PubMed/ Medicine, EMBASE and Cochrane library databases. Statistical analyses were carried out using either random-effects or fixed-effects models according to the heterogeneity of eligible studies. Results: Six eligible trials involved 601 patients were identified. Compared with current therapies, treatment schedules with selumetinib did not improve progression free survival (hazard ratio, 0.91; 95%CI 0.70-1.17, P= 0.448), but did identify better clinical benefits (odds ratio, 1.24; 95%CI 0.69-2.24, P = 0.472) and less disease progression (hazard ratio, 0.72; 95%CI 0.51-1.00, P = 0.052) though its impact was not statistically significant. Sub-group analysis resulted in significantly improved progression free survival (hazard ratio, 0.61; 95%CI 0.49-0.57, P = 0.00), clinical benefits (odds ratio, 3.04; 95%CI 1.60-5.77, P = 0.001) and reduced disease progression (hazard ratio, 0.35; 95%CI 0.18-0.67, P = 0.001) in patients administrated selumetinib. Dermatitis acneiform (risk ratio, 9.775; 95%CI 3.143-30.395, P = 0.00) and peripheral edema (risk ratio, 2.371; 95%CI 1.690-3.327, P = 0.00) are the most frequently observed adverse effects associated with selumetinib. Conclusions: Compared with current chemotherapy, selumetinib has modest clinical activity as monotherapy in patients with advanced cancer, but combinations of selumetinib with cytotoxic agents in patients with BRAF or KRAS mutations hold great promise for cancer treatment. Dermatitis acneiform and peripheral edema are the most frequently observed adverse effects in patients with selumetinib.

Purpose: The purpose of this paper was to analyze the physicochemical properties related to peeling rate of Korean chestnut. Methods: Analyses were carried out for weight, thickness, polyphenol, amino acid and peeling ratio for Korean chestnut. The correlation between these physicochemical components and peeling ratio of chestnut was measured. Results: The average of thickness for inner shell and outer shell was 0.66 mm and 0.93 mm, respectively. The average peeling ratio was 77.51%. A significant negative correlation was found between peeling ratio and thickness of the inner shell ($r=-0.80^{***}$, p<0.001). Analysis for the polyphenol composition of inner shell by HPLC was carried out and peaks 2 ($r=-0.56^*$, p<0.05), 11 ($r=-0.68^{**}$, p<0.01), 14 ($r=-0.52^*$, p<0.05), 28 ($r=-0.66^{**}$, p<0.01) showed a significant negative correlation with the peeling ratio. Conclusion: Thickness of chestnut inner shell was determined as the most influential factors of peeling.

The study was designed to observe the effects of dietary intake of three different levels of polyunsaturated to saturated fatty acid (P/S) ratio on plasma HDL - cholesterol and triglyceride in plasma and tissues of adult rats. Rats were assigned into the three diet groups, composed of protein 24%, carbohydrate 46%, and fat 30% of total caloric intake. However, the P/S ratio of fat was adjusted by using beef tallow, corn oil and perilla oil to give 0.2, 1.1 and 6.0. All groups were fed ad libitum for 4 week. Plasma cholesterol level was decreased but net significantly with increasing P/S ratio of dietary fat, and showed significant negative correlation coefficient. Plasma TG level was also decreased with increasing PUFA level of dietary fat. However, the effect of P/S ratio (6.0) was not greater than that of P/S ratio (1.1) on plasma TG concentration. This implied that high level of PUFA was not required to change plasma TG level as much in the case of HDL-cholesterol. Plasma HDL-cholesterol was significantly increased only in the group of P/S ratio 6.0 which suggested that high level of dietary PUFA was required to increase HDL level. There was a decreasing trend in the levels of total cholesterol and TG per g liver with increasing P/S ratio of dietary fat. There was no effect in the levels of TG per g skeletal muscle by P/S ratio but the level of cholesterol per unit skeletal muscle was rather increased with increased P/S ratio.

In this study, lab-scale phosphorus coagulation/precipitation experiments were performed using three types of polyaluminum chloride (PAC) with different Al contents (10%, 12%, and 17%). The PO₄-P removal efficiencies at various operating conditions, such as initial PO₄-P concentration, initial pH, and Al/P molar ratio, were evaluated, and correlations among the operating factors affecting phosphorus coagulation/precipitation with PAC were derived to optimize the process efficiency. When the initial PO₄-P concentration was 0.065 and 0.161 mmol P/L under an initial pH of 8-10, the optimal PAC dose was 0.126-0.378 and 0.189-0.667 mmol Al/L, respectively. Under these conditions, the Al/P molar ratio was 2.16-6.18 and 1.28-4.30, respectively, and the PO₄-P removal efficiency was in the range of 40.2-92.5%. When the Al/P molar ratio was 2 or less under an initial pH condition of 6-8, the PO₄-P removal efficiency was approximately ≤40% owing to insufficient Al³⁺ ions. However, when the Al/P molar ratio is 3-5, the PO₄-P removal efficiency improved to approximately 80-90%. Thus, the optimal Al/P molar ratio to achieve a PO₄-P removal efficiency of over 90% was determined to be approximately 4 in the PO₄-P coagulation/precipitation process using PAC.

본 논문에서는 P2P 라이브 스트리밍 시스템에서 각 피어의 캐싱과 프리페칭 영역 비율을 조절하여 성능을 향상시키는 버퍼링 기법을 제안한다. 이를 위해 재생 시점을 기준으로 피어들을 그룹핑한 후 그룹 내 각 피어의 상대적인 재생 시점에 따라 캐싱과 프리페칭을 적응적으로 결정한다. 즉, 피어의 재생 시점이 최근일수록 캐싱 영역의 비율을 증가시키고 이른 시점일수록 프리페칭 영역을 증가시킴으로써 그룹 내 피어들 간에 버퍼맵 구간의 중복 정도를 크게 높일 수 있다. 마지막으로 시뮬레이션 실험을 통해 본 논문에서 제안하는 프리페칭/캐싱 통합 버퍼링 기법이 기존 고정 영역 버퍼링 기법보다 평균 지터 비율, 초기 재생 지연 시간 및 공유 가능한 버퍼맵 비율 등에서 우수한 성능을 나타낸다는 것을 보인다.

Purpose: This study was aimed to determine the optimum low-density lipoprotein : high-density lipoprotein-cholesterol (LDL : HDL-C) ratio for predicting coronary heart disease(CHD) in Korean people. Methods: It was analyzed this data of 5,431 adults who had undergone health examinations in a hospital in Gyeonggi-do between January 2006 and December 2007. The covariation of the coronary risk factors such as age, HbA1C, systolic blood pressure(SBP), and waist-to-stature ratio(WSR) were analyzed by using logistic regression analysis. Results: The LDL : HDL-C ratio in the male and female groups was mostly distributed between 1.5 and 4.0. The LDL : HDL-C ratio was the most significant cholesterol-related parameter influencing CHD (male: B = .306, p = .054, female : B = .940, p = .010), followed by LDL-C and total cholesterol. It was observed a sharp increase in the odds ratios for LDL : HDL-C ratios of 2.25 - 2.50(male) and 2.00 - 2.25(female). A significant difference was observed in both male(2.25 : $x^2$ = 2.494, p = .072) and female(2.00 : $x^2$ = 413.742, p = .000) groups. Conclusion: The risk level of CHD was set to 2.25 for males and 2.00 for females. Therefore, the optimum LDL : HDL-C ratio for Koreans should be far lower than that for the people in western countries.
