The third latitude survey in cosmic-ray neutrons has been carried out along the same ship-route and by using the same apparatus as in the preceeding two surveys. Although the observation room was the same as that in the second survey, one additional room was constructed over our room. Thus, as observational conditions in the three latitude surveys are different from one another, the obtained results could not be compared in absolute intensity but in relative. The periods during which each survey was performed are represented with the corresponding sunspot relative numbers in Fig. 1, where a full curve shows the 12 months running average of monthly mean values in sunspot numbers. Fig. 2 shows 12 hour mean values for each latitude curve in the southern hemisphere. It is seen from the figure that the slope of latitude curve becomes gentle at the second survey and then almost recovers at the third. To explain such changes in primary cosmic-rays by terms of changes in solar activity represented by sunspot numbers as shown in Fig. 1, we suppose a hysteresis effect of solar activity upon cosmic-rays. In other words, changes in cosmic-rays do not immediately follow that in solar activity but about half a year later.

当初,南極観測用に製作された宇宙線中性子観測装置は,IGY用として設計されたもので,全体の重量が6トンを超えるため,ヘリコプター輸送に適さない.そこで重量軽減化の方法として,(1)ニュートロン減速剤として,パラフィンの代りに現地の海水を利用する.(2)真空管方式の増幅,計数装流をすべてトランジスター化する.の2点から,新しい観測装置を製作した.この装置は重量約500kgで,第4次観測隊により無事基地へ空輪された.観測は1960年3月3日より開始された.観測結果の一部として,日平均値の変化及び5月4日の宇宙線異常増加の結果を示した.

Twitter evidently stirred a popular trend of personal update sharing. Twitter users can be kept up to date with current information from Twitter; however, users cannot obtain the most recent information, while they browse web pages since these are not updated in real time. Meanwhile, there are many events happen at any time such as crowded restaurants and time sales in different floors or areas at composite facilities in urban areas. To solve them, it is thought that an appropriate method is to detect tweets of small-scale facilities at a composite facility to enrich their traditional web pages. Therefore, we developed a tweet visualization system to support users grasp event happens over time and space from tweets while they browse any web pages based on spatio-temporal analysis of tweets. In order to detect and analyze tweets of a composite facility, the system maps geo-tagged tweets to web pages by matching their location names, and classifies the tweets into different categories of small-scale facilities by utilizing machine learning algorithms. Thus, the system can visualize tweets in a tag cloud is associated with a web page to help users immediately gain a quick overview of events through space and time while they browse this web page, and it can also effectively present a list of most related tweets to help users obtain more detailed information about events. In this paper, we discuss our spatio-temporal analysis method and we have also included an evaluation of tweet classification into small-scale facilities and tag cloud generation that feature words of tweets are changed over time.
