Differencies of lipid composition of murine sarcoma virus 97017 transformed rabbit kidney cells and their plasma membranes in monolayer and suspension culture were studied. Free cholesterol was the major neutral lipid extracted from the whole cells and plasma membranes of all these cultures. Triglyceride increased about 6 to 50 folds in suspension grown whole cells and their plasma membranes compared to those from monolayer cultures. The μ mole of total neutral lipids and phospholipids are elevated in plasma membranes compared to whole cells from monolayer cultures bur arc similar in suspension cultures. The distribution of fatty acids in the major lipid classes of plasma membranes and whole cells generally follow the composition of calf serumused in the culture media.

Nowadays, juvenile's sexual-related delinquency is increasing and their immature sexual behavior is on issue with this recent phenomenon. That is the reason people realize offering right sex education for them is important. So, we are going to study for trying to make an improvement in sex education field based on the fact that is practicing now at school. We will reference "소중한 성 바로알기" in this study which is published in 2008 for schoolteacher to compensate some limitations of former education material. This study was done from June 15 to July 20, 2009(Total : 36days) and aimed for surveying senior year students of middle school located in Seoul, S. Korea. We sampled 248 students by random from 8 classes of 4 schools. We analyzed final 209 samples(the other 39 samples were omitted for inappropriate response and return.) using SPSS WIN 12.0. The questionnaire includes 4 parts of relationship and psychosexual, physical growth and sexual health, social environment and sexual equality, and healthy family with marriage and it consists of 31 questions. We made this questionnaire base on the reference as we stated above. From this study we found the part of healthy family with marriage has not enough contents compared with the other 3 parts. And also we could see students don't feel satisfaction with one-off, one-sided sex education, and the education which is performed with only one single method. Therefore we make a judgement that middle school students have their needs toward sex education at school and those are considered as regular education by well-trained education provider, and various means for education such as case study, discussion, or role play. As well we think sex education for middle school students need to offer more about sexual equality and also alert the increasing possibilities of sexual commit in cyber space to adolescent.

Lingamdinne, L.P.,Chang, Y.Y.,Yang, J.K.,Singh, J.,Choi, E.H.,Shiratani, M.,Koduru, J.R.,Attri, P. Elsevier 2017 CHEMICAL ENGINEERING JOURNAL -LAUSANNE- Vol.307 No.-

The accumulation of heavy metal ions in living cells impairs the organ function of living creatures. So, needs to develop new materials with high efficiency of heavy metals removal from the environment. As part of this effort, here, synthesized magnetic inverse spinel iron oxide nanoparticles (MISFNPs) using a biogenic methodology. To synthesize the biogenic MISFNPs, we used the seed extract of Cnidiummonnieri (L.) Cuss (CLC) as a precursor. The prepared MISFNPs was characterized using PXRD, FT-IR, SEM-EDX, SEM, BET, AFM and XPS. We also investigated the size, surface area, structure and magnetic properties of MISFNPs. Additionally, magnetic property measurement system (MPMS) studies show that our prepared MISFNPs was superparamagnetic at room temperature. Further, we used the MISFNPs for the removal of Pb(II) and Cr(III) from aqueous solutions through batch studies. Batch adsorption studies revealed that Pb(II) and Cr(III) follow pseudo-second-order kinetics during adsorption onto the homogenous surface of MISFNPs. Besides, we also found that the adsorption of Pb(II) and Cr(III) on nanoparticles followed an endothermic process. Lastly, we concluded that MISFNPs synthesized by a green route is capable of recycling and removal of heavy metals without loss of its stability.

Purpose: Human Papillomavirus (HPV) vaccination is readily available, but immunization rate is minimal. Lack of knowledge concerning the HPV infection and vaccine is expected as the primary reason. The correlation between knowledge levels and vaccination will provide applicable guidelines for successful interventions. Method: 309 female university students have completed surveys September 2016, reporting of HPV infection knowledge, HPV vaccine knowledge, source of knowledge, and attitudes concerning vaccination. Result: HPV infection and vaccine knowledge levels were both suboptimal(9.57±1.84, 7.59±1.58), and the Internet(16.2%) was recognized as the most generally used means of obtaining information on the HPV vaccine. However, vaccination rates were reported to be low(28.2%), with lack of information(46.6%) hindering immunization. Correlations were found between HPV infection knowledge and cervical cancer insight, but the correlations between knowledge levels and vaccination rates were insignificant. Conclusion: Prior information on cervical cancer had an effect on the knowledge levels of HPV infection, but other factors were insignificant. Lack of information on the HPV vaccine was speculated, thus programs should focus on accessibility and effectiveness.

A Study of Radioactive Contamination of <tex> $^{\text{40}}\text{Ca}^{\text{100}}\text{MoO}_{\text{4}}$</tex> Crystals for the AMoRE Experiment

<P>A calcium molybdate (CaMoO4) crystal scintillator, with molybdenum enriched in Mo-100 and calcium depleted in Ca-48 ((CaMoO4)-Ca-40-Mo-100), was developed by the Advanced Molybdenum based Rare process Experiment (AMoRE) collaboration to search for a neutrinoless double beta (0 nu beta beta) decay of Mo-100. We are planning to use about 10 kg of (CaMoO4)-Ca-40-Mo-100 crystals as cryogenic bolometers for the first phase of the experiment (AMoRE-I) at the Yang Yang underground laboratory (Y2L) in Korea. This experiment calls for an extremely low level of radioactive contamination in detectors, particularly by thorium, uranium, and radium decay chains. We measured scintillation properties and radioactive contamination of CaMoO4 and (CaMoO4)-Ca-40-Mo-100 crystals at the Y2L. We also estimated the acceptable level of internal radioactive background using Monte Carlo simulation for the AMoRE-I.</P>

Tetrahydropteridine deficiency impairs mitochondrial function in Dictyostelium discoideum Ax2

Kim, H.L.,Choi, Y.K.,Kim, D.H.,Park, S.O.,Han, J.,Park, Y.S. North-Holland Pub ; Elsevier Science Ltd 2007 FEBS letters Vol.581 No.28

A putative cellular function of tetrahydropteridines (l-erythro-tetrahydrobiopterin and d-threo-tetrahydrobiopterin) was investigated in Dictyostelium discoideum Ax2 using a mutant disrupted in the gene encoding sepiapterin reductase (SR). The SR mutant, which produces about 3% of tetrahydropteridines if compared to wild-type, was elucidated to have several functional defects related to mitochondria and oxidative stress: retarded growth, poor spore viability, impaired mitochondrial function, and increased susceptibility to oxidative stress induced by hydroxylamine or cumene-hydroperoxide. However, the physiological defects were almost completely rescued by extrachromosomal expression of Dictyostelium SR. The results strongly suggested that tetrahydropteridines in Dictyostelium are associated with mitochondrial function, probably via direct protection against oxidative stress.

We try to analysis comparing the measurements by wheat-stone bridge method at room temperature of the magnetoresistance (MR) measured with the current in the layer planes (CIP) and the current perpendicular to the layer planes (CPP) for the samples that we prepare equal and unequal thickness Ag/Co multilayers on glass substrates in a vacuum of ?? Torr by a thermal vacuum evaporation method. We try to consider the correlation between the magnetoresistance curve obtained from X-Y recorder and the magnetic hysteresis curve examined by vibrating sample magnetometer for the CIP and the CPP each other. The MR(H) curves are similar in shape for the CPP and CIP orientations, and also the magnetic fields, ?? in which MR peaks appear are nearly same for each orientation. Maximum MR dadas for the CIP and the CPP (CIP-MR, CPP-MR) with varing Ag thickness show the same variation, and unlike Fe/Cr or Co/Cu, the Ag/Co multilayers do not oscillate with Ag thickness. The CPP-MR appear from 1 times to 6 times as large as the CIP-MR for the same samples.

Ohh, S H,Shinde, P L,Jin, Z,Choi, J Y,Hahn, T-W,Lim, H T,Kim, G Y,Park, Y,Hahm, K-S,Chae, B J Poultry Science Association, etc 2009 Poultry science Vol.88 No.6

<P>Two experiments were conducted to evaluate potato protein (PP, experiment 1) and refined PP (RPP, experiment 2) obtained from Gogu valley tubers as an antimicrobial agent in broiler diets. In both the experiments, 1-d-old male Ross 308 chicks were allotted to 5 treatments and performance, nutrient retention, and microbial populations in excreta and cecum were studied. Dietary treatments were as follows: basal diet (negative control, NC), basal diet with antibiotic (positive control, PC, 10 mg/kg of avilamycin), and low, medium, or high levels of PP (0.25, 0.50, and 0.75%, respectively, in experiment 1) or RPP (200, 400, and 600 mg/kg, respectively, in experiment 2). The overall gain and retention of DM (d 20 to 21) and CP (d 20 to 21 and d 41 to 42) were greater in birds fed PC and high PP diets than birds fed the NC diet. Population of total aerobic bacteria and coliforms was lowest in the cecum and excreta of birds fed the PC diet and highest in birds fed the NC diet. An increase in dietary PP linearly improved BW gain, feed intake, and feed conversion ratio during starter phase and overall BW gain. Also, there was linear improvement in retention of DM (d 20 to 21) and CP (d 20 to 21 and d 41 to 42) and reduced populations of total aerobic bacteria and coliforms in the cecum (d 42) and excreta (d 28 and 42) due to an increase in dietary PP. In the second experiment, the PC diet and diets with increasing levels of RPP had no effect on performance and nutrient retention. Birds fed the PC diet had the lowest microbial population in excreta and cecum, whereas the population of total aerobic bacteria and coliforms in excreta and cecum decreased (linear, P < 0.05) as the level of RPP was increased in the diet. These results suggest that both PP and RPP obtained from Gogu valley potato tubers have in vivo antimicrobial activity.</P>
