<P><B>Abstract</B></P> <P>G<SMALL>EANT</SMALL>4 is a software toolkit for the simulation of the passage of particles through matter. It is used by a large number of experiments and projects in a variety of application domains, including high energy physics, astrophysics and space science, medical physics and radiation protection. Over the past several years, major changes have been made to the toolkit in order to accommodate the needs of these user communities, and to efficiently exploit the growth of computing power made available by advances in technology. The adaptation of G<SMALL>EANT</SMALL>4 to multithreading, advances in physics, detector modeling and visualization, extensions to the toolkit, including biasing and reverse Monte Carlo, and tools for physics and release validation are discussed here.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Multithreading resulted in a smaller memory footprint and nearly linear speed-up. </LI> <LI> Scoring options, faster geometry primitives, more versatile visualization were added. </LI> <LI> Improved electromagnetic and hadronic models and cross sections were developed. </LI> <LI> Reverse Monte Carlo and general biasing methods were added. </LI> <LI> Physics validation efforts were expanded and new validation tools were added. </LI> </UL> </P>

In order to find a way to reduce histamine formation when storing salted mackerel at home, a series of experiments were carried to monitor the time-related changes of histamine content, total aerobic bacteria and coliform quality of mackerel marketed in Incheon by the type of storage containers (clean, zipper and vacuum bag) during storage at 4°C, 24°C and -20°C for 10 days. Histamine formation was continuously increased with passing time during storage at 4°C, whereas it was decreased after 3 days during storage at 24°C. The initial value of histamine was maintained during storage at -20°C for 10 days. During storage at 4°C, total aerobic bacteria and coliform showed a tendency to increased rapidly till 3day and then decreased gradually. The formation of histamine was increased in the order of vacuum bag<zipper bag<clean bag during storage at 4°C.

力學滑走台에 의한 重力加速度 "g"의 測定

南相敦,崔福源 부산교육대학교 과학교육연구소 1982 科學敎育硏究 Vol.7 No.-

This experiment was tried for the measurement of the acceleration of gravity "g" with air track. Therefore, it was required to take a photograph of the slider motion on the air track in order to measure the acceleration with the poloride camera used stroboscope in dark room. After that, The data of the mean value of the accelertaion was measured by the film analysis. The experimental result is showed as the following; experiment 1 A measuremental value of "g" in the case of inclined plane of air track is; g=9.93m/sec^2 experiment 2 A measuremental value of "g" in the case of horizontal plane of air track by method of freely falling bodies used the weight is; g=9.75m/sec^2

어제 훈민정음을 통해 본 15세기 국어학자들의 언어의식

박지홍 釜山大學校 師範大學 1979 교사교육연구 Vol.6 No.1

1.It seems to me that liuguists of the Korean language in our country in the time of inventing the Korean alphabet in the latter part of the 15th century had the accurate consciousness of language. They thought that a concept was first formed in their heads, then it was changed into "malssa^(ˇ)m", than it became speech, and then it came out of their teeth. The "malssa^(ˇ)m" and speech expressed at that time were thought to be language when they were combined together. It in clear that they were conscious that letters were not to carry speech, but to carty "malssa^(ˇ)m". 2. Judging from how words were constructed, they also seem to have been conscious of word formation. Seen through the documents handed down in the time of the 15th century, it is supposed that they were conscious, though vaguely, of both simple and compounds words, and that they were conscious of the difference between derivatives and compounds words. 3. It seems to me, too, that they were a quite deeply conscious of parts of speech, which we can bully see through examining the interpretation of chinese characters throughout the whole books of the Korean translation of chinese originals in the 15th century. They were also conscious that parts of speech were divided into substance and expletive, and that substance were composed of words, with the ending of "-이라" (which corresponds to what is now called an uninflected word), of words ending with "-을씨" (which corresponds to what is now called an inflected word), and of words showing only meanings (which correspond to what is now called modifiers). It is clear that they understood that expletive were divided into prepositions and postpo- sitions, that prepositions were composed of those which were used when speech began (which cossespond to what is now called interjections), of those which were used when they followed after the words mentioned before (which correspond to what is now called conjunctions), and of prepositions in general; that postpositions were composed of postposition in general, and of those which were used when speech came to an end (which correspond to what is now called ending words), This is all of lingnistic consciousness that the linguists of the Korean language in the 15th century had, it seems.

Gas sensing with heterostructures based on two-dimensional nanostructured materials: a review

Bag, Atanu,Lee, Nae-Eung The Royal Society of Chemistry 2019 Journal of Materials Chemistry C Vol.7 No.43

<P>Gas sensors are being used in diverse applications in security, food safety, environmental monitoring, indoor air quality monitoring, personal healthcare, <I>etc.</I> During the past decade, two-dimensional (2D) nanostructured materials have attracted intense attention because of their unique chemical and physical properties. They have demonstrated promising potential for gas sensing devices because of their large surface-to-volume ratio, high surface sensitivity, and excellent semiconducting properties. Combining 2D nanostructured materials with other dimensional materials also holds great promise for developing high-performance gas sensors. This review presents a comprehensive summary of recent progress in gas sensors with advanced heterostructures based on 2D nanostructured materials. Furthermore, the fundamental sensing mechanisms of different types of gas sensors are systematically discussed, and key device architectures and their performances are summarized. Finally, the challenges and prospects for the future development of each type of gas sensor are addressed to promote better sensing-device architectures.</P>

It is very important to analyze the characteristic of fishing gear at coastal fishery. And the auther has investigated the materials of mainline and branchline, the number of yarn in twine and the constitution of them on the longline gear of 5 species (96 pieces) using in the near sea of Jeju Island and have some results as follows; 1. The materials of mainline is composed of cotton 35.4%, PVA 47.9%, PES 10.4% and combined fibre (PE plus PES cont. fil.) 6.3%. And its branchiline is composed of cotton 45.8%, PVA 46.9% and PA 7.3%. 2. The thick rate of mainline and branchline is revealed that the branchline is a quarter of mainline in cotton and one-thirds in PVA. In the blanquillo longline gear, the relation between branchline(y) and mainline (x) is found to be; cotton; y = 0.1902x + 5.1913 PVA ; y = 0.2729x + 3.2399 3. The length of mainline is composed of chiefly 300-360 m, and 1.1-1.3 m for the branchline, in the blanquillo longline gear. 4. The interval of branchline is made up 43% at more than twice, and 5.7% at less than twice, to compare with the length.

Among Korea, China and Japan, they have their own language amusements. It goes without saying that Korea and Japan as well as China have common Chinese characters amusements beside their own langage amusements. In China they have Mi-un(微言), Su-sa(庾辭), mataphor(隱語), and riddle(字謎), Also they have low-class parodies and highly technical 'Whoe-moon(回文)' Poem, 'Bak-ka-eu(百家衣)' style poem, 'Tsang-woon(雙韻)' Poem, and 'Yun-koo(聯句), Poem In Korea beside many language amusements they have 'Pa-ja(破字)' riddle and 'Un-moon pung wol(諺文風月)' etc. In Japan they have their particular(Sha-re 酒落), 'Haya-guchi(早口)', 'karu-guchi(輕口), as well as 'Bustu-mei-ka(物名歌)', Mono-wa-ztuke(物者附)', Zap-pai(雜俳)' etc. In this thesis I have handled the common language amusement of 'Whoe-moon' style poem in those three countries.
