As the Internet has become prevalent, the popularity of net media has been growing, to a point that it has taken over conventional mass media. However, TWtrends, the Twitter trends visualization system operated by our research team since 2019, indicates that many topics on TV programs frequently appear on Twitter trendlines. This study investigates the relationship between Twitter and TV programs by collecting information on Twitter trends and TV programs simultaneously. Although this study provides a rough estimation of the volume of tweets that mention TV programs, the results show that several tweets mention TV programs at a constant rate, which tends to increase on the weekend. This tendency of TV-related tweets stems from the audience rating survey results. Considering the study outcome, and the fact that many TV programs introduce topics popular in social media, implies codependency between Internet media (social media) and mass media.

本稿は, パーソナル・ネットワークに対する都市効果を, 階層的に異なる水準で測定された変数を扱うマルチレベル分析を用いて明らかにすることを目的とした. 具体的には, 個人レベルの属性の影響を統制したうえで, 地域レベルの都市度が, 親しい親族・隣人・友人数およびその空間的分布に及ぼす文脈効果を検討した. データは, 東京都, 神奈川県, 埼玉県, 千葉県内の30自治体に居住する25歳以上の男女4,676人から得た.分析の結果, 第1に, 親族総数の地域差は居住者の個人属性の影響を統制すると消失した. しかし都市度は親族関係の空間的分布に影響を及ぼしていた.都市度が高いほど近距離親族数は減少していたのである. 大都市の親族関係は, 規範的ではなく選択的であり, 空間的に分散したネットワークである点が示唆された. 第2に, 都市度が高いほど隣人数は減少していた. 第3に, 友人総数の地域差は居住者の個人属性の影響を統制すると消失した. しかし都市度は友人関係の空間的分布に影響を及ぼしていた. 都市度が高いほど, 中距離友人数が増大していたのである. 都市度は, 都市圏全体に広がる友人資源へのアクセス可能性を高めている点が示唆された.

Previously unknown ancient remains were detected in the Memphite necropolis of Egypt by the analysis of satellite data. As one of the result, a brick architecture with a small pyramid of the new kingdom was discovered at Dahshur which is some 20km south from Giza. It was the first discovery in Egypt using this new method. This study is being done in cooperation with Tokai University Research & Information Center and The Egyptian Culture Center of Waseda University.The main purpose of this study is to detect undiscovered pyramids in Egypt with the aid of satellite remote sensing technology and ecological analysis of the Egyptian dynastic period. Satellite remote sensing technology is expected to be a powerful tool for a wide range observation in the field of archaeological study. Multiple satellite data, i. e., Landsat-TM, SPOT-PAN, SPOT-XS, KVR-1000, JERS 1-SAR, EERS 1-SAR and maps based on archaeological research, were used for this study. The discovery of the remains was made in the process of the study. The result of this study clearly shows that satellite remote sensing technology is a very useful in archaeological observation.

There are many uncertainties in the knowledge of modern sciences, especially the sciences of complex systems. Here, in the first I discuss the pseudo-sciences and indicate the pseudo-scientific tides due to the uncertainties of complex systems, whose origins are made clear such as chaos, self-organization, butterfly effect, and so on. The uncertainties are intrinsic in complex systems. In the next, I present the possible role of scientific communication, especially stressing how the scientific communicators overcome the uncertainties of sciences. This will become a fatal point of scientific communication. Finally, I add the possible cooperation between the natural and social scientists.

After the media coverage of Afghan "Burqa" and recent revival of the dispute over "Scarves" in Europe, the Muslim woman's veil has been attracting a great deal of public attention. Extensive literature exists on this topic, but little has been done for understanding the basis of the debate-the Qur'an and its interpretation by Muslims. Therefore, as the first step to understand the meanings of the veiling of women in the Islamic cultural context, three relevant passages from Qur'anic Revelation are examined in this paper. Analysis of these passages with a number of hadith clarifies that the veil was, at first, adopted by Islamic society to distinguish free women from slaves, and to protect their safety (33:59). The "Revelation of Hijab" (33:53) which descended to the wives of the Prophet Muhammad, also secured and distinguished their status. Then 31 of Sura al-Nur (24) had come, as follows: "And tell the female believers that they restrain their eyes and guard their private parts, and not display of their adornment (zina) except for what is apparent (ma zahara min ha) and draw their veils (khimar) over their bosoms…" The words contained in this passage, such as "adornment" and "what is apparent," are very obscure. To decide the limits or the extent of the coverage, religious scholars and jurists had to interpret this passage, and because there was no solid hadith on this part, the meanings changed over time. At first, face and hands could be exposed, but around the 13th century, some scholars interpreted that those parts of the body should be covered if there were "a fear of fitna". Fitna is a temptation, a disorder of mind and society. This idea led to the severe restrictions on women showing their faces and hands; the restrictions sometimes extended to barring women from leaving their homes. This tendency is seen not only in the religious literature but also in other historic or literary sources from 10th to 16th century. Even today, the word "fitna" is used in religious literature. For example, the Taliban mandated the "Burqa" because of this fear of fitna. The fitna is one of the many reasons for the tradition of veiling Muslim women, past and present.

1. There were found marked individual differences in the vascular reaction to cold reported by Lewis which protects the temperature fall of fingers or toes in severe cold. The difference should be an essential factor in constitutional difference of resistance against frost damage.2. A method was devised to determine the temperature reaction to cold by dipping the middle finger of the subject in ice water for 30 minutes, and measuring its skin temperature, and to compare the reactivity of the subject with one another by evaluating the so-called. “resistance index of frost bite” from the temperature curve thus determined. The method was called “a point test of the resistance against frost bite”.3. The resistance index estimated by the method was fairly reproducible, as far as the experimental conditions were constant. When measuring repeated attempts should, however, be avoided unless after several hours, and to have such living conditions before and during the measurement that do not cause changes in the thermoregulatory function.4. A marked seasonal change was found in the temperature reaction of one and the same subject, which increased in summer, and decreased in winter. The change was found to be mainly due to the change of room temperature. Even at the same room temperature, however, the reaction differed a little in summer and winter, i. e. is accelerated in the former when compared with the latter. The difference is probably due to an acclimatization of the vasomotor centre, in which the tonus changes to dilation of the skin vessels of extremities in summer, and constriction in winter.5. Influences of environmental temperature were examined in detail and it was found that the reactivity was accelerated by rise in room temperature in proportion with the magnitude of the reactivity itself. This fact can be explained by the fact that the reactivity of vessels is controlled by the tonus of the vasomotor, especially of the vasodilator, which changes with the environmental temperature.6. Effects of humidity on the temperature reaction was proved to exist, but not so marked as those of room temperature.7. Making use of the above experimental results, a method was devised to eliminate the errors in the temperature reaction due to the change of room temperature, and to evaluate the resistance index at the standard temperature of 20°C. from measurements at other temperatures. It was found that 81%-94% of values thus corrected coincided with those actually measured at 20°C. withinthe scope of experimental error, when the room temperature was between 15C°C. to 25°C.

We propose a new weight compensation mechanism with a non-circular pulley and a spring. We show the basic principle and numerical design method to derive the shape of the non-circular pulley. After demonstration of the weight compensation for an inverted/ordinary pendulum system, we extend the same mechanism to a parallel four-bar linkage system, analyzing the required torques with transposed Jacobian matrices. Finally, we develop a 3 D.O.F manipulator with relatively small output actuators and verify that the weight compensation mechanism greatly contributes to decrease static torques to keep the same posture within manipulator's work space.
