본 연구에서는 초등학교 4-6학년을 대상으로 첫째, 비만도에 따른 아동의 심리사회적 적응과 체력 수준의 차이를 밝히고, 둘째, 비만도와 체력이 과체중 이상 아동의 심리사회적 적응에 미치는 영향을 살펴보았다. 과체중 이상 아동은 '한국 비만 아동의 신체 활동과 건강(KOCPA)' 연구의 비만 캠프 프로그램에서, 대조군 아동은 서울 시내 초등학교에서 표준 성장도표의 체질량지수를 기준으로 모집되었다. 심리사회적 변인으로 자아 효능감 검사(식이 자아 효능감, 체중 조절 효능감, 신체 효능감), 자아개념검사, 소아용 삶의 질 검사가 사용되었으며, 신체 계측 및 체력은 직접 측정되었다. 연구 결과, 비만도가 증가할수록 심리사회적 적응과 체력 수준이 낮은 것으로 나타났다. 또한 과체중 및 비만 아동은 정상체중 대조군에 비해 유의하게 낮은 효능감 및 자아개념, 삶의 질을 보고하였다. 과체중 및 비만 아동을 대상으로 심리사회적 적응에 비만도와 체력, 두 변인의 상호작용이 미치는 영향을 알아본 결과, 체력이 좋을수록 높은 체중조절 효능감, 신체 효능감, 삶의 질이 예측되었다. 또한 비만도와 체력의 상호작용 효과가 비만 아동의 자아개념 수준을 예측하였는데, 이는 비만도가 그리 높지 않은 아동들은 체력 수준의 향상이 자아개념을 유지할 것이라고 예측 가능하지만 비만도가 상대적으로 매우 높을 경우에는 우선적으로 비만도의 감소가 우선적으로 이루어져야 함을 시사한다. 본 결과를 바탕으로 본 연구의 함의와 한계점에 대해 논의하였다.

Backgrounds Diabetes mellitus is associated with accelerated atherosc lerosis and predispose to specific microvascular problems. This study was performed to evaluate the usefulness of red ginseng as adjunctive therapeutic agent of NIDDM especially in preventing chronic diabetic complications. Materials and Methods We treated 50 patients with NIDDM for 5 month with 2 regimens: 1)oralhypoglycemic drug therapy only(the control group), 2)oral hypoglycemic group). The patients were recruited at Korea university hospital from June, 1992 to October, 1992 and the following inclusion criteria were used: l)age above 35 years 2)initial body weight within or above ideal body weight 3)fasting blood glucose level greater than 140mg/dl 4)no previous history of diabetes mellitus or no history of blood glucose control for recent 3 months of more. The patients were seen every 2 weeks for remaining 3 months. At every visit FBS and PP2hr blood glucose were measured with blood pressure and body weight. Lipid profiles were checked every 4 weeks and platelet function test was perfomed with aggregometer after administration of ADP, epineprine and collagen every 4 weeks. Free fatty acid were also analyzed every 8 weeks and glycosylated hemoglobin was measured every 12 weeks. Results The results were as follows: 1. The mean values for fasting and PP2hr blood glucose decreased significantly in the control group than in the ginseng group. 2. The weight gain was less in the ginseng group than in the control group. The levels of systolic blood pressure decreased' significantly in the ginseng group than in the control group. 3. There was no significant differences of lipid profiles in both groups. 4. The platelet hyperaggregation was improved more significantly in the ginseng group than in the control group. Conclusions In patients with NIDDM who were recieving oral hypoglycemic drug therapy, the addition of red ginseng improved platelet function and blood pressure, but induced less weight gain. The data suggests that red ginseng may be useful as a therapeutic adjunct especially in preventing chronic complications of NIDDM.

The purpose of this study was to evaluate the effect of replacing soybean meal with treated castor meal with (CMT) or without lime (CMNT) on the nutrient intake, performance, carcass characteristics, and yield of commercial cuts of beef cattle from a feedlot. Thirty male, castrated, crossbreed zebu cattle were used in the study, with an average initial weight of $360{\pm}30.27\;kg$. Five animals were used as a control group and were slaughtered at the beginning of the experiment; the remaining animals (n = 25) were distributed in random blocks (repetitions), with body weight as the criterion for block assignment. The animals were fed a diet containing 65% corn silage and 35% of concentrate on dry matter (DM) basis. Five diets consisted of four levels of soybean meal (SM) substituted with CMT (0, 33, 67 and 100%) on a DM basis and a diet with 100% of SM replaced with CMNT. At the end of the experiment, all animals were slaughtered, and their gastrointestinal tracts were emptied to determine their empty body weights (EBW). No significant effects were observed (p>0.05) for the substitution of soybean meal with CMT on intake of dietary nutrients, the average daily body weight gain (ADG) or EBW gain (EBWG). In spite of greater (p<0.05) ricin intake for the diet containing CMNT (3.06 mg/kg BW) compared to the CMT diet (0.10 mg/kg BW/d), there were no effects (p>0.05) on intake of dietary nutrients, ADG or EBWG. The average intake of DM and the ADG were 10,664.63 and 1,353.04 g/d, respectively. Regarding carcass characteristics, only carcass yield in relation to body weight was linearly reduced (p<0.05) upon substitution of SM by CMT. There was no effect (p>0.05) of the substitution of SM by CMT or CMNT on the yield of carcass basic cuts. CMT prices that are higher than 85% of the SM price do not economically justify the use of CMT. For CMT prices between 20 and 80% of the SM price, the optimal level was 67% substitution, while for prices below 15% of the SM price, the optimal level was 100% substitution with CMT. It can be concluded that treated castor meal with 6% lime can totally replace soybean meal in beef cattle diets.

The Purpose of this study was to investigate the effect of the change in misture content on some physical properties of grains, and some relations amont the properties. Materials included ere rough rice, brown rice, barley and wheat with the range of moisture content of 6~26 percent, 7~25 percent, 10~24 percent and 6~22 percent, respectively. Kernel dimension, sphericity, kernel weight, and volume were included as the physical properties of the grains. The results obtained are summarized as follows; 1. The ratio of grain length to the thickness was in the range of 3.59~4.16 for rough rice(Indica type), 2.98~3.27 for rough rice(Japonica type), 3.25 for brown rice (I.T.), 2.14~2.38 for brown rice(J.T.), 2.92~3.13 for barley and 2.10~2.21 for wheat, respectively. 2. The sphericity was found to be 42 percent for rough rice(I.T.), 48 percent for rough rice(J.T.), 52 percent for brown rice(I.T.), 62 percent for brown rice(J.T.), 45 percent for barley and 61 percent for wheat, respectively. 3. The kernel weight of grains was linealy increased with the increase of moisture content. At a specified moisture centent of 14 percent, the kernel weight was shown to be in the range of 4.72${\times}10^{-5}$~3.58${\times}10^{-5}$kg for wheat, 3.60${\times}10^{-5}$~3.12${\times}10^{-5}$kg for barley, 2.80${\times}10^{-5}$~2.35${\times}10^{-5}$kg for rough rice, and 2.24${\times}10^{-5}$~1.82${\times}10^{-5}$kg for brown rice, respectively. 4. The kernel volume was linearly increased with increase of moisture content. The rate of increase was significantly low for rough rice in comparison with the remaining grains. The kernel volume, at a specified moisture content of 14 percent, was in the range of 3.51${\times}10^{-8}$~2.76${\times}10^{-8}m^3$ for wheat, 2.84${\times}10^{-8}$~2.43${\times}10^{-8}m^3$ for barley, 2.93${\times}10^{-8}$~1.97${\times}10^{-8}m^3$ for rough rice, and 1.61${\times}10^{-8}$~1.29${\times}10^{-8}m^3$ for brown rice, respectively. 5. The kernel volume of grains was found to be related to the length, width, thickness and kernel weight as a exponential function. The kernel volume was shown to have correlation coefficient to the length factor rough rice and barley which were of low sphericity, while the width factor was predominant for brown rice and wheat which was of high sphericity.

Understanding adipocyte development in fetus during bovine pregnancy is important for strengthening fattening technology. Additionally, nutritional level of dams during pregnancy has the potential to improve offspring growth and fat development. The purpose of this study is to evaluate the intramuscular adipocyte development and expression level of related genes in bovine fetus, and the effect of increased crude protein (CP) intake during pregnancy on the growth performance and carcass characteristics of male offspring. Eighty six pregnant Hanwoo cows (average body weight, 551.5 ± 51.3 kg, age 5.29 ± 0.61 y) were used. Fetuses were collected at 90, 180 and 270 d of gestation from 18 pregnant Hanwoo cows. The remaining 68 pregnant cows were randomly assigned to 2 feeding groups. The control (CON) group was provided the standard protein diet (n = 34), and treatment (TRT) group was provided a diet with a 5% increase in CP intake (n = 34). Male offspring were divided into two groups according to protein treatment of the pregnant cows: CON male offspring (CON-O) and TRT male offspring (TRT-O). Intramuscular adipocytes were found in the fetal skeletal muscle after 180 days of gestation. Male calf's birth weight increased in the TRT group compared to that in the CON group (p < 0.002). The final body weight (p < 0.003) and average daily gain (p < 0.019) of male offspring were significantly higher in TRT-O than in CON-O. The feed conversion ratio was also improved by 10.5% in TRT-O compared to that in CON-O (p < 0.026). Carcass weight was significantly higher in the TRT-O group than that in the CON-O group (p < 0.003), and back fat was thicker in the TRT-O group (p = 0.07). The gross receipts and net income were higher in TRT-O than in CON-O (p < 0.04). Thus, fetal intramuscular fat can be formed from the mid-gestation period, and increased CP intake during pregnancy can increase net income by improving the growth and carcass weight of male offspring rather than intramuscular fat.

본 연구에서는 딸기에 대한 고분자 키토산의 수확 전후 처리가 과실의 품질과 부패에 미치는 영향을 조사하였다. 키토산 처리는 수확한 딸기의 잿빛곰팡이병 억제, 과실의 경도 증진 및 표피의 광택을 유지시키는 효과가 명확하였다. 그러나 0.2% 농도 키토산 4회 누적적인 처리도 식물 자체에 생리적 장해를 일으키지 않으며 내적 품질에 현저한 영향을 미치지 않았다. 키토산 처리의 효과는 물리적 손상이 없을 경우 우수하였으며 손상을 받은 과실에서는 명확한 선도유지효과를 나타내지 않았다. 수확 후 처리의 효과는 명확하지 않았으며 수확 전 처리 효과를 증대시키지 않았다. 이상의 결과로 볼 때 키토산은 화학적 방제를 배제할 수 있는 수단으로 과실의 경도 증진, 부패 억제를 통한 품질 향상의 대안이 될 수 있는 것으로 판단된다.

Objective: The aim of the present study was to determine the effect of supplementing pasture-finished steers with corn silage on the expression level of the calpain system proteins and beef tenderization. Methods: Thirty Braford steers grazing on summer pasture were used for the study. For 120 days fifteen animals were supplemented with corn silage at 1% of body weight per head per day (Suppl) whereas the remaining 15 steers only received pasture (Contr). Carcass and meat traits were evaluated and compared between groups. Gene expression and activities of proteases (calpain 1 and calpain 2) and inhibitor (calpastatin) were measured using real-time polymerase chain reaction and casein zymography. Results: Carcass and meat traits were significantly different between feeding systems. Supplemented steers showed higher hot carcass weight (p<0.01), fat content (p = 0.02), and Warner-Bratzler shear force (p = 0.03). Furthermore, the control group showed higher protease:inhibitor ratios, at mRNA (p = 0.01) and protein levels (p<0.10). Warner-Bratzler shear force and mRNA calpains:calpastatin ratio were associated in both feeding systems (p<0.01). Conclusion: Based on the results obtained in the study, beef tenderness differences among finishing strategies could be modulated through differential expression of the calpain system proteins.

Objective : The purpose of this study was to investigate the patterns and the risk factors of newly developed vertebral compression fractures (VCFs) after percutaneous vertebroplasty (PVP). Methods : We performed a retrospective review of the 244 patients treated with PVP from September 2006 to February 2011. Among these patients, we selected 49 patients with newly developed VCFs following PVP as the new VCFs group, and the remaining 195 patients as the no VCFs group. The new VCFs group was further divided into 2 groups : an adjacent fractures group and a nonadjacent fractures group. The following data were collected from the groups : age, gender, body weight/height, body mass index (BMI), bone mineral density (BMD) score of the spine and femur, level of initial fracture, restoration rate of anterior/middle vertebral height, and intradiscal cement leakage, volume of polymethylmethacrylate (PMMA). Results : Age, gender, mean body height/weight, mean BMI and volume of PMMA of each of the group are not statistically significantly associated with fractures. In comparison between the new VCFs group and the no VCFs group, lower BMD, intradiscal cement leakage and anterior vertebral height restoration were the significant predictive factors of the fracture. In addition, new VCFs occurrence at the adjacent spines was statistically significant, when the initial fracture levels were confined to the thoracolumbar junction, among the subgroups of new VCFs. Conclusion : Lower spinal BMD, the greater anterior vertebral height restoration rate and intradiscal cement leakage were confirmed as risk factors for newly formed VCFs after PVP.
