This paper analyzes modularity in biological and cultural evolution. Evolutionarily modularized or quasi-independent biological traits can vary relatively independently from other traits and have higher variability, and developmentally modularized biological traits have robust developmental processes and higher variability and heritability. First, I point out that these two concepts should not be confused. Second, by focusing on the concept of evolutionary modularity, I argue that it can increase (and actually have increased at least in some cases) evolvability also in the context of cultural evolution if cultures are modularized through looking at some specific examples of cultural evolution.

In this study, based on the daily maximum wind speed and maximum instantaneous wind speed data recorded at 61 observation points operated by the Korea Meteorological Administration from 1993 to 2018, the self-organizing map clustering method was used to classify regions with similar characteristics of strong wind and gust wind occurrence and intensity. Characteristics of these regions were analyzed by averaging 30 variables related to wind for each cluster. As a result, 13 homogeneous regions of strong wind and gust wind in Korea were identified, which were clearly divided into regions of high and low strong wind frequency of occurrences. In most regions, the average daily maximum wind speed and maximum instantaneous wind speed were high in spring and winter. However, the average daily maximum wind speed and maximum instantaneous wind speed exceeding the criteria of strong wind (14 m s−1) and gust wind (20 m s−1) in this study were high in summer and autumn. Among the four clusters with high occurrence of strong wind and gust wind, one was classified as a specific region with high occurrence in summer and autumn. This results are likely to be beneficial to support regional customized special weather reports and disaster prevention.

The oxidation of pure titanium was studied in superheated steam at 400∼550°C. The effects of prior cold working and several heat treatment conditions on the oxidation were examined and also the effects of the addition of small amounts of iron and oxygen were investigated. The oxidation mechanism of pure titanium is discussed in relation to the scale structure and the oxidation kinetics. Hydrogen absorption rate was also measured. As a result, the following conclusions were drawn:(1) The oxidation of pure titanium in steam was faster than in air and breakaway oxidation was observed above 500°C after the specimen had gained a certain weight. Prior cold working and heat treatment conditions scarcely affected the oxidation rate, whereas the specimen containing small amounts of iron and oxygen showed a little more rapid oxidation.(2) At 500 and 550°C a dark grey inner scale and a yellow-brown outer scale were formed. The outer scae was apt to exfoliate after the occurrence of breakaway oxidation. At 400 and 450°C only a dark grey scale was observed. All of these oxides were identified as the rutile type, TiO2. Furthermore, the presence of a thin and uniform oxygen rich layer beneath the external scale was confirmed at all test temperatures.(3) The measured weight gain approximately followed the cubic rate law; this would be expected for the following reason; one component of the weight gain is due to the dissolved oxygen, the amount of which remains constant after the early stages of oxidation. The second component is due to the parabolic growth of the external TiO2 scale. When these contributions are added a pseudo-cubic weight gain curve results.(4) It was shown that 50 percent of the hydrogen generated during the oxidation was absorbed into the metal.

パスツールが狂犬病ワクチンを開発し,1885年に人に接種してから128年たち,確かに先進国における犬猫の媒介する狂犬病の発生数は目に見えて減少,もしくは淘汰されてきた。しかしWHO/FAO/OIEの推計によると毎年約6万人の死者が報告されており,WHOの推計によるとアジアとアフリカで未だに毎年約55,000人以上(アジアで約31,000人,アフリカで約24,000人)の死者がでていると推計されている。アジアではインドの狂犬病患者が最も多く,次いで中国である。現在,世界で狂犬病の清浄国は,わずか8ヵ国(英国,日本,スエーデン,アイスランド,ノルウエー,オーストラリア,ニュージーランド,シンガポール)である。アメリカは野生動物狂犬病の汚染国であるが,ハワイやグアム島は清浄地域である。また太平洋には狂犬病のない沢山の小島が存在している。世界の狂犬病の発生状況は図1)にまとめてある。狂犬病はすべての哺乳類に感染するが,狂犬病ウイルスの研究が進むにつれて,いろいろな野生動物からウイルスが分離されるようになり,狂犬病ウイルスの他に狂犬病に関連するリッサウイルスが存在することが分かってきた。

The Non-Hydrostatic Regional Climate Model (NHRCM) was used in simulating the present and future rainfall climate over Malaysia under the RCP8.5 scenario in this study. Simulation and projection from 1979 to 2002 for present day and 2070 to 2100 for the end of century were conducted over the Malaysia. The 20 km resolution MRI-AGCM3.2 model simulation from Meteorological Research Institute (MRI) was used as boundary conditions. The objective of this study was to estimate the extreme rainfall projections in Malaysia at 5 km of resolution during the November to February period, representing the northeast monsoon season. Overall, the model was capable to simulate the historical rainfall climatology and distribution, but model tended to underestimate high rainfall frequency and mean rainfall intensity in Malaysia. However, compared with simulations at 25 km, added values have been shown at 5 km resolution. Based on the NHRCM05 simulations, a number of hotspots have been identified with significant projected increases up to 80% for the extreme rainfall indices (R20mm, RX1day, R95pTOT and R99pTOT), 30% increases in mean rainfall intensity (SDII) and 20% for consecutive dry days indices (CDD).

Woman's eye is one of the most important motives in Man Ray's works. However, in his images of woman's eye, the organ of sight is quite often manipulated, sometimes even violently, and the images acquire a very uncanny nature. This uncanny manipulation of woman's eye in Man Ray's oeuvre, both in photographs and objects, can be divided into four categories : "the Gazing Monster or Surrealist Medusa, " "the Enucleated Eye, " "the Closed Eye, " "Beheading." The last can be regarded as the manipulation of woman's eye, because it is a way of punishing a woman with evil eyes like Medusa, who is exterminated by Perseus through decapitation. The uncanny nature created by these manipulations squarely corresponds to the Freudian concept of the Uncanny. In his analysis of uncanny effects in E, T, A, Hoffmann's novel, The Sand-Man, Freud defines the source of the uncanny as the castration anxiety symbolized by the eye torn out. All the four types of manipulations in Man Ray's images of woman's eye can be found in this or other Freud's essays on the castration anxiety. By visualizing this anxiety repressed in the unconscious or "the return of the repressed, " Man Ray created the true Surrealist image of the emancipation from the reason and order through the direct manifestation of the unconscious.
