姜禧信,高永杜 慶尙大學校 1975 論文集 Vol.14 No.-

Two metabolism trials by 6 Korean Native Female Goats, aged about two years old, were conducted by the two 3×3 latin square design to study the voluntary intake of feed and utilization of total dietary nitrogen. The experimental feeds used were 1) sun cured Acacia leaf and 2) the pellet composed of 21% barley, straw meal, 0.5% urea, and 71% concentrates as shown in the Table 1. The first trial was designed to feed the pellet as a basal to which the sun cured Acacia leaf was supplemented, while the second was to alter the basal and the supplementation; Acacia leaf as the basal and the pellet as the supplementation. The results obtained were summarized as follows; 1) The pellet supplementaion to the basal diet of Acacia leaf resulted in an increased D. M. intake and could retard the live weight reductions which were shown by the goats fed the pellet as a basal feed. 2) The goats fed Acacia leaf alone were gained their weights by about 446 g/day whilst the animal fed the pellet alone lost weights at the rate of 1520g/day. 3) The digestibility of D. M. O. M. and total nitrogen of the sun cured Acacia leaf were determined to be 45.2, 47.7 and 39.6%, respectively.

이용호,신용돌,이영희,김희중,강일구 全北大學校 基礎科學硏究所 1991 基礎科學 Vol.14 No.1

간편하고 경제적인 transformer-ratio-arm bridge 회로를 자체 제작하여 몇 가지 잘 알려진 물질의 자기변형을 측정하였다. 전기용량 변환기에 진공 증착한 Al 전극판을 사용하여 와류효과를 줄였다. Bridge의 분해능은 10^-4pF정도였으며 7Å 정도의 길이변화의 분해능을 얻었다. Metaglass 2605SC,2605CO,2826MB에 대해 측정한 결과 공표치와 일치함을 보였다. An economical magnetostriciton measurement system is built. Using simple transformer-ratio-arm bridge we get the resolution of 7Å in length and 10^-4pF in capacitance. Vacuum coated thin film of Al is used as electrodes for the length-to-capacitance transducer which greatly reduces the eddy current cause varying magnetic field and improves sensitivity. The obtained results for well known Metglass 2605SC, 2605CO and 2826MB show good agreement with published data.

기판위에 자성박막을 증착한 시료를 자장속에 넣을 때 박막의 자기변형에 의하여 생기는 시료의 굴곡을 전기용량으로 변환하여 측정하는 방법을 써서 Ni의 다결정 박막의 자기변형을 측정하였다. 유리기판위에 18150 Å의 Ni 박막을 증착한 시료의 포화자기변형은 38 × 10 exp (-6) 이었으며 bulk 시료의 값과 대체적으로 일치하였다. 고능률의 소형 전자석과 디지탈 기억의 순간 측정법에 의하여 온도변화의 측정 장해요소는 크게 감소되었다. Thin film magnetostriction is measured with capacitance method. A Ni film 18150 Å thick is vacuum deposited on a glass substrate. The sample is cantilevered on a flat metallic holder and bends under applied magnetic field by magnetostriction of the film. Change of capacitance between the film and holder is measured with transformer bridge method. Magnetostriction of the sample is calculatd with sample geometry, Young's moduli of the film and substrate and the change of capacitance. The magnetostriction of the Ni film turns out to be 38 × 10 exp (-6) which is almost same as that of bulky sample. Temperature, change of the sample is minized with using high efficiency small electromagnet and instantaneous measuring method by digitizing oscilloscope.

생리활성을 지닌 신경펩타이드의 구조와 활성간의 관계를 규명하기 위하여 고상법으로 합성한 세종류의 neuropeptide γ(mammalian-,trout- 그리고 goldfish-neuropeptide γ)를 사용하여 연구하였다. Circular dichroism spectra에 의하면 mammalian-,trout- 와 goldfish-neuropeptide γ는 완충액 조건하에 모두 random한 구조를 나타내었다. 중성 및 산성 지질 존재 하에서, mammalian-과 trout- neuropeptide γ는 여전히 random한 구조를 취하였다. 그러나, goldfish-neuropeptide γ는 중성 및 산성지질하에서 부분적으로 α-helix구조를 나타내었다. 장관 수축활성에 있어서는 carp 장관, guinea-pig 회장 그리고 rat십이지장에 대하여 비교하였다. Carp에 대해서는 goldfish-neuropeptide γ= trout- neuropeptide γ>mammalian-neuropeptide γ순으로 활서이 나타났다. 그러나, guinea-pig 회장과 rat십이지장에 대해서 mammalian-neuropeptide γ는 어류 유래성 neuropeptide g들 보다 높은 수축활성을 나타내었다. 이러한 결과들은 neuropeptide γ들이 종-특이적인 활성을 나타낸다는 것을 제시한다. The relationship between structure and biological activity was studied on the three neuropeptides(mammalian-,trout- and goldfish-neuropeptide γ)that were syntheized by the solid-phase method. Circular dichroism spectra showed that mammalian-,trout- and goldfish-neuropeptide γadopted an undered structure in buffer solution. In the presence od neutral and acidic liposomes, mammalian-and trout- neuropeptide γ also took a random structure. However, goldfish-neuropeptide γ took an α-helical structure in acidic liposomes. The intestinal motility response was investigated with carp interstines, guinea-pig ileums and rat duodenums. In case of carp intestine, contractine activity was as follows:goldfish-neuropeptide γ= trout- neuropeptide γ> mammalian-neuropeptide γ. On the other hand, the contracile activity of mammalian-neuropeptide γ was more potent than trout- and goldfish-neuropeptide γ in the guinea-pig ileums and rat duodenums. these results suggest that neuropeptide γs showed the species-specific activity.

Kang, Han-Lim,Kim, Chul Am,Lee, Sang-Il,Shin, Yong-Kwan,Lee, Yun-Hi,Kim, Young-Cho,Ju, Byeong-Kwon IEEE 2016 Journal of display technology Vol.12 No.7

<P>We analyze the movement of particles in an electric paper that consists of upper and lower electrodes. Particles inserted in a fluid move under the influence of an electric field when voltage is applied to the electrodes. The movement of particles is determined by the intensity of the electric field, the viscosity of the fluid, and the of the particles. Each factor has an impact on the independent particles. Considering these factors, we analyze the characteristics of the particles' movements. We analyze the behavior of the electric paper with experiments based on Stokes' Law.</P>

This study is aimed at offering basic data about prevention of Hepatitis B virus and infection control to dental hygiene students who will work mostly at dental offices which are characteristically exposed to a high risk of HBV infection. For this study, surveyed were 188 sophomores and juniors of the dental hygiene department who volunteered to undergo the tests of HBsAg and HBsAb. The examination of the blood collected from the samples and analysis of their perception about hygiene resulted in following conclusion: Positive HBsAg Four was found in 4 testees(2.1%) while 118(62.8%) revealed positive. HBsAb. Juniors showed higher positive rate in HBsAb whereas sophomores had higher positive rate in HBsAb. But such difference has statistically no significance. Generally, students seemed to pay little attention to HBV, judging from the survey of their perception about the present state of HBsAb and HBsAb(p>0.05), conduct of infection(p<0.05), completion of 3 requested vaccination(p>0.05), and formation of antibody(p>0.05). With regard to the infection routes of HBV, most students(92.4%) replied "through blood", which is statistically insignificant, though. Next ratio goes to the reply "through contaminated injectors". This reply came more from sophomores than from juniors, a difference which is statistically significant(p<0.05). The lowest rate of possible infection(29.2%) was thought to be "through breast-feeding of a positive mother"(p<0.05). In general, it turned out that sophomores had more knowledge about the infection routes of HBV than juniors. In terms of clinical history among family members, 6(3.1%) reported that some of their family members are currently suffering from a liver complaint, 3(1.6%) replied their family members were once afflicted, and 4(2.1%) said their members died of hepatitis. Except 10(4.7%), all the surveyees replied that their states of health are better than normal. Generally, sophomores are healthier than juniors except for very health case, a difference which is statistically of no value.
