This study in to know the development transition of juveniles age(10∼17 of ages) about the relationship of natural developmental, patterns, according to sexes, ages and regions by vertical and crossing methods. To analyze the degree developed through intended training and its related meaning, the objects are chosen from 4 regions(urban, farming and mining community etc). The objects for vertical study are 2000 persons : crossing study, 6400 : experimental study, 320 The results through analyzing statistical date by electronic computer, based on the materials investigation, measurement and experiment, from July 1 to Nov. 30 1987, are following 1. The aspect of the form This report was represented that the body measurement value of the height, the weight, the chst-girth, and the sitting height was continuously increased the growth development till 10∼17 age, according to increased with age, and the cross-sectional change have a tendency both for male and female to excess crossing change. 2. The aspect of the function (in the viewpoint of action fitness element) 1) This report was showed that the fitness of the male continuously in creased till 17 ages, and that of the female in distinctly decreased or maintained after 14 ages. 2) The exercise items prevailed the crossing change were the speed (100M sprint), the power (throwing) and endurance of total body (longtime running (female)) And the exercise items prevailed the vertical change were the power (long jump), endurance (muscle endurance : chinning, chin hanging, sit-ups, endurance of total body : 800M and 1,000M lony-time running) 3. The results through experiments 1) Grip strength (1) Maximal strength The development of strength is almost parallel to the development of body and it shows rapid development speed, especially, in the adolescent juveniles. (2) Muscle Endurance There are outstanding development in both sexes. Because the development speed become slow after being 15 of ages, applying muscle endurance training from being 14 of ages is effective. 2) Long-time running In both sexes the rate of increase is high after they are 15 years old (or after being of 15 ages). To anticipate the good effect of training of long-time running, therefore, it is effective to apply the training after they are 15 years old (or after being 15 ages)

This study is designed to grasp the elements and situations of stage fright in order to propose a part of ways to cope with it. We make 511 top-class high school players, male and female, in the central districts (Seoul, Inchon, Kyungki, Chungbuk, and Kangweon Province) on object of questionnaire, and get the following results. Through players generally have all-round characters they show weakness in the superiority and emotional stability while showing strength in the sonformity. This fact comes to be related to the elements which cause stage fright. Physiological changes also have many effects on the symptom of stage fright. Especially, stage fright increases when players show sensitive reaction to the self-consciousness of final consequence which comes from the tension or uneasiness of sympathetic nerve, Thus, it turns out that players make use of reducing psychological burden by physical exercise or adjusting the level of demanded result in order to release the stage fright.

The probability of failure is used to analyze the reliability of three dimensional slope failure, instead of conventional factor of safety. The strength parameters are assumed to be normal variated and beta variated. These are interval estimated under the specified confidence level and maximum like-lihood estimation. The pseudonormal and beta random variables are generated using the uniform probability transformation mehtod according to central limit theorem and rejection method. By means of a Monte-Carlo Simulation, the probability of failure is defined as; Pf=M/N N : Total number of trials M : Total number of failures Some of the conclusions derived from the case study include; 1. Three dimensional factors of safety are generally much higher than 2-D factors of safety. However situations appear to exist where the 3-D factor of safety can be lower than the 2-D factor of safety. 2. The F3/F2 ratio appears to be quite sensitive to c and Φand to the shape of the 3-D shear surface and the slope but not to be to the unit weight of soil. 3. In cases that strength parameters are assumed to be normal variated and beta variated, the relationships between safety factor and the probability of failure are fairly consistent, regardless of the shape of the 3-D shear surface and the slope. 4. As the c-value is increased, the probability of failure for the same safety factor is increased and as the Φ-value is increased, the probability of failure for the same safety factor is decreased.

연 x-선 현미경은 ‘물의 창’ 영역(2.3~4.4 nm)의 파장을 이용하여, 수십 nm의 분해능으로 세포를 파괴하지 않고 살아있는 상태에서 세포의 내부구조를 관찰할 수 있어 가시광선현미경과 전자현미경을 단점을 보완하는 특징을 갖는 세포 생물학 연구에 적합한 현미경이다. 그러나 기존 연 x-선 현미경은 광원으로 방사선 가속기를 이용하기 때문에 사용이 제한적이었다. 이에, 본 연구에서는 2.88 nm의 연 x-선을 광원으로 사용하는 소형 연 x-선 현미경을 이용하여, 내포작용에 의해 금 나노입자를 포획한 HT1080과 MDA-MB 231 세포의 영상을 약 60 nm 분해능으로 획득하였다. 금 나노입자의 세포에 대한 독성을 제거하기 위하여 폴리에틸렌 글리콜을 캡핑하였고, 2.88 nm 파장의 연 x-선에 대하여 충분한 조영효과로 인하여 세포영상에서 뚜렷한 대조도를 나타내었다. 내포작용에 의해 액포에 포함되어 있는 다양한 크기의 금 나노입자 군집을 확인하였으며, 세포내부의 액포의 분포상태도 관찰할 수 있었다. 따라서 고분해능을 가진 소형 연 x-선 현미경을 이용하여 금 나노입자를 세포내의 미세기관이나 특정 단백질에 표지하면 연 x-선에 대한 조영효과의 증가에 의하여 더욱 유용한 정보를 획득할 수 있을 것으로 생각한다. A compact soft x-ray microscope operated in the ‘water window’ wavelength region (2.3~4.4 nm) was used for observing cells with nano-scale spatial resolution. To obtain cellular imaging captured with colloidal gold nanoparticles using a compact soft x-ray microscope. The colloidal gold nanoparticles showed higher contrast and lower transmission more than 7 times than that of cellular protein on the soft x-ray wavelength region. The structure and thickness of the cell membrane of the Coscinodiscus oculoides (diatome) and red blood cells were seen clearly. The gold nanoparticles within the HT1080 and MDA-MB 231 cells were seen clearly on the soft x-ray microscopy. The gold nanoparticles were aggregated within vesicles by endocytosis.

Hong, Jang-Kwan,Lee, Kwang-Nyeong,You, Su-Hwa,Kim, Su-Mi,Tark, Dongseob,Lee, Hyang-Sim,Ko, Young-Joon,Seo, Min-Goo,Park, Jong-Hyeon,Kim, Byounghan American Society for Microbiology 2015 Applied and environmental microbiology Vol.81 No.21

<P>Three out of five outbreaks of foot-and-mouth disease (FMD) since 2010 in the Republic of Korea have occurred in the winter. At the freezing temperatures, it was impossible to spray disinfectant on the surfaces of vehicles, roads, and farm premises because the disinfectant would be frozen shortly after discharge and the surfaces of the roads or machines would become slippery in cold weather. In this study, we added chemical deicers (ethylene glycol, propylene glycol, sodium chloride, calcium chloride, ethyl alcohol, and commercial windshield washer fluid) to keep disinfectants (0.2% citric acid and 4% sodium carbonate) from freezing, and we tested their virucidal efficacies under simulated cold temperatures in a tube. The 0.2% citric acid could reduce the virus titer 4 logs at −20°C with all the deicers. On the other hand, 4% sodium carbonate showed little virucidal activity at −20°C within 30 min, although it resisted being frozen with the function of the deicers. In conclusion, for the winter season, we may recommend the use of citric acid (>0.2%) diluted in 30% ethyl alcohol or 25% sodium chloride solvent, depending on its purpose.</P>
