This information will provide useful data for a more systematic desirable, and practical sex education. The data was collected from 300 first grade schoolchildren (150 boys and 150 girls) of two Junior high school in Kcity. The data was gathered by questionnaire from Nov.21 to 28, 1995. The questionnaire was modified by authors using the questionnaire developed by Lief & Reed. Data was analyzed by using the statistical computer package, SAS to mainpulate the data along with percentages, means, standard deviation, t-test, ??-test GLM, and Pearson correlation coeffiency. The results in this study were summarized as follows : 1. Sexual knowledge. - The mean score of sexual knowledges showed no significant differences between boys and girls(p<0.6180), but in the areas of biological differences(boys; 11.57±2.43, girls; 10.93±2.41, p<0.0242), and pregnancy physiology(boys; 9.28±1.87, girls; 10.04±2.42, p<0.0026) showed significant difference between boys and girls. 2. Sexual attitudes. - The mean score of sexual attitudes showed no significant differences between boys and girls(p<0.8286), but in the areas of masturbation(boys; 6.69±2.22, girls; 5.65±1.88, p<0.0001), and premarital intercourse (boys; 5.42±1.35, girls; 6.00±1.33, p<0.0002) showed significant difference between boys and girls. 3. Need of sex education. - The majority of the subjects wanted to learn about sexual delinquency and it's prevention(57.7%), form a friendship with the other sex(56.3%), physical differences of the other sex(52.0%), psychological differences and the characteristics of the other sex(50.3%) and meaning of love(50.3%). 4. The relationships between sexual knowledges and sexual attitudes. - Those who had higher sexual knowledges showed more positive attitudes towards sex, and showed statistical significance(r=0.2074, p<0.0003). 5. The relationships bwtween general characterisitics and sexual knowledge. - Better students(by self-perception of shool performance) had higher knowledge scores about sex. 6. The relationships bwtween general characterisitics and sexual attitudes. - Those who wanted to learn about sex, and better students had higher attitude scores about sex. - Those who were in high stadard of living had higher sttitude scores sex as well. Suggestions based on above study are as follows: 1. The planned sex education schowed be performed to the schoolchildren establish responsible attitudes about sex. 2. Systematic sex education through formal shool education according to age is recommended. 3. Further studies should be done to measure the effect of sex education based on the needs of the schoolchildren.

Background and Objectives: This study was done to compared the distribution of the two calcium-binding proteins immunoreactive neurons, parvalbumin immunoreactiv (PV-IR) and calbindin D-28K immunoreactive (CB-IR) neurons in the spinal cord after transection. Materials and Methods: Twenty rats were divided into 3 groups (control, complete spinal cord injury (SCI), and right and left spinal cord hemisection). SCI was produced by cutting the spinal cord use blades 11 with scalpel handles. Results: In this experiment, CB-IR neurons were mainly found in many pyramidal cells distributed in the brain stem and spinal cord of rats. PV-IR Neurons were demonstrated in all lamina of the gray matter of the spinal cord. These immunoreactive cells had the highest density in the layer I and II of dorsal horn and several nuclei of the ventral horn of the all the segments of the spinal cord. CB-IR neuropil labeling was strongly noted in all the segments of the spinal cord. In contrast PV-IR neurons were different in distribution, size and morphology in the spinal cord. The number of PV-IR neurons were greater than in the spinal cord compared with the CB-IR neurons. CB-IR and PV-IR somata were round, oval, spindle and polygonal in shape, and were unipolar, bipolar, multipolar and horizontal in types. The diameters of the somata of the PV-IR and CB-IR neurons were 40-50 ㎛, respectively. Also dendrites of PV-IR and CB-IR neurons were densely arrayed in network.

( Jae Won Byun ),( Kyung Hyun Lee ),( Ha Young Kim ),( Soon Seek Yoon ),( Ji Youl Jung1 ),( Woo Seog Jeong1 ),( Jae Ku Oem ),( Jong Soo Lim ),( Myoung Heon Lee ),( You Chan Bae ) 한국예방수의학회(구 한국수의공중보건학회) 2013 예방수의학회지 Vol.37 No.1

Nine cattle among 18 in a native Korean herd died or were euthanized within 3 days. The affected cattle showed cowshed. The pigs and dogs had been fed leftover food originating from nearby restaurants, and the cattle could presumably reach the contaminated food in the pig troughs. Necropsy revealed a few chicken bones and red pepper pieces as well as large amounts of grain and rice straw hay mixed in the rumen. Botulism type D was isolated in the ruminal contents of one of the cattle. We speculated that the outbreak was associated with the cattle incidentally eating presumably contaminated leftover food from the pig trough.

The purpose of this study is to substitute water-based painting materials for the current solvent-based ones used in motor-repairing process to minimize the exposure of organic solvents to the painters. This study assessed the exposure of organic solvents to the painters using water-based and solvent-based painting materials and compared compositions, painting processes and the health hazards of the application of these alternative painting materials. The results of this study are as follows. 1. solvent-based painting materials used in motor-repairing process consist of various organic solvents, which consist primarily of toluene, xylene, ethyl benzene, ethyl methyl bezene, trimethyl bezene, ethyl acetate, butyl acetate, methyl isobutyl ketone, 2-ethoxy ethanol, 2-ethoxy ethyl acetate and toluene-2.4-diisocianate and the others. These organic solvents are know as health-hazardous substances. But water-based painting materials are high-solid, low-solvent ones and consist of such two organic solvents as 2-butoxy ethanol and 2-heptanone and the others. 2. The painters using solvent-based painting materials in motor-repairing process are exposed to various organic acetate, methyl isobutyl ketone, trimethyl benzene, 2-ethoxy ethanol, and 2-ethoxy ethyl acetate. But the painters using solvent-based ones are only exposed to 2-butoxy ethanol and 2-heptanone. 3. By using water-based painting materials in stead of solvent-based painting materials containing health-hazardous organic solvents, the exposure of such organic solvents in the painter's breathing zone can be largely prevented. 4. This study recommends water-based painting materials as substitutes for the current solvent-based ones used in motor-repairing process to minimize the exposure of organic solvents to the painters.

The production of near- and off-shore fisheries in South Korea is decreasing due to rapid changes in the fishing environment, particularly including higher sea temperature in recent years. To improve the competitiveness of the fisheries, it is necessary to provide fish catch information that changes spatiotemporally according to the sea state. In this study, artificial intelligence models that predict the CPUE (catch per unit effort) of mackerel, anchovies, and squid (Todarodes pacificus), which are three major fish species in the nearand off-shore areas of South Korea, on a 15-km grid and daily basis were developed. The models were trained and validated using the sea surface temperature, rainfall, relative humidity, pressure, sea surface wind velocity, significant wave height, and salinity as input data, and the fish catch statistics of Suhyup (National Federation of Fisheries Cooperatives) as observed data. The 10-fold blind test results showed that the developed artificial intelligence models exhibited accuracy with a corresponding correlation coefficient of 0.86. It is expected that the fish catch models can be actually operated with high accuracy under various sea conditions if high-quality large-volume data are available.

The created 30 nm scale phase change memory cell (aerial array density: ∼207 Gbit inch<SUP>−2</SUP>) showed a threshold switching voltage of 1.1 V, a value compatible to conventional phase change memory cells. More significantly, the cell could be amorphized by a reset pulse of 1.8 V height and 100 ns width, where the reset current was 100 μA. Such a low reset current, presumably caused by nanoscale small cell dimension, is greatly beneficial for low power consumption device operation. Reversibly, the set operation was accomplished by crystallization with a set pulse of 1.2 V height, 100 ns width, and 100 ns trailing. This work provides a significant step for low power consumption and ultra-high density storage based on phase change materials.</P> <P>Graphic Abstract</P><P>Ultra-high density and low power phase-change memory (aerial array density: ~207 Gbit inch<SUP>−2</SUP>) was fabricated <I>via</I> block copolymer lithography and straightforward two-step ICP-RIE etching. <IMG SRC='http://pubs.rsc.org/services/images/RSCpubs.ePlatform.Service.FreeContent.ImageService.svc/ImageService/image/GA?id=c1jm14190b'> </P>
