The Red-Back Spiders (Latrodectus hasselti) were found in all parts of Australia except in the hottest deserts and on the coldest mountains. The spider is now generally recognized as being the same family as the Katipo Spider of New Zealand and the Black Widow Spider of America. This species is the only representative of the genus Latrodectus in Australia. The Red-Back Spider was probably the most common cause of serious spider bites between 1927, when records were first kept, and 1956, when an anti-venom became available. The authors redescribe and figured detailly Red-Back Spider,L. hasselti, which was collected during a field trip of Australia.

A total of 631 species of spiders have been reported in Korea. However, there are no spiders with noxious venom such as Latrodectus sp. Because of this, to date, no serious medical problems due to spider bites have been reported in Korea, and only two cases of spider bite were officially reported. However, as the number of earning spiders from other countries is increased, the number of cases of spider bite has also shown a recent increase. A 17-year-old man presented with numbness of both extremities after being bitten by a spider which he had as a pet. The spider is called an Indian ornamental tree spider (Poecilotheria regalis sp.), one kind of tarantula species. Herein, we report on a case of a spider bite by a tarantula.

Combined with expert interviews and questionnaire investigations, this paper aims at analyzing the different characteristics of the animated characters Spider-Man from Spider-Man: Into the Spider-Verse based on Hunlock Effect, in order to provide appropriate guidance for animation characters designers and limited inspiration for creative practices. First, Spider-Man: Into the Spider-Verse is chosen as the case to analyze 6 Spider-Man with different personalities, who appear at the same time. Then, Spider-Man's characteristics are analyzed through interviews with experts. At last, the key study focuses on the influence of environmental factors on the formation of Spider-Man's roles in the theory of Hunlock Effect, in light of the principle of personality formation in psychology. From the perspective of psychology, interdisciplinary study on animated characters provides scientific and effective support for animation character design, and increases the fascination of animation characters' personalities.

Spectral phase interferometry for direct electric-field reconstruction (SPIDER) was fabricated and used to characterize pulses from a Ti:sapphire oscillator. In the SPIDER apparatus, two replicas of the input pulse were generated with a time delay of 200 fs and were upconverted by use of sum-frequency generation with a strongly chirped pulse using a 8-cm-long SFIO glass block at a 30-11m-thick type II BBO (p-BaBz04) crystal. The resulting interferogram was recorded with a UV-enhanced CCD array in the spectrometer. The spectral phase was retrieved by SPIDER algorithm in combination with independently measured pulse spectrum and the corresponding temporal intensity profile was reconstructed with a duration of 19 fs. As an independent cross-check of the accuracy of the method, we compared the interferometric autocorrelation (lAC) signal calculated from the SPIDER data with a separately measured lAC. The conventional, but unjustified, method of fitting a sechz pulse to the autocorrelation deceivingly yielded a pulse duration of 15 fs. This systematic underestimation of the pulse duration affirms the need for a complete characterization method. From the consideration in this paper, we concluded that the SPIDER could provide an accurate characterization of femtosecond pulses. ulses.

Since the first episode of (1995) by Pixar, a world leading animation company, 3D animation has been focused on realistic motion and rendering techniques. However, in 2018, 3D animation was released, with unique backgrounds created through illustration techniques and dynamic movements of characters that seemed to be produced by hand rather than computers. It shows a lot of difference from other 3D animations. In this study, I analyzed 's new production techniques and expressions into two categories, first, the use of old comics techniques, and second, other factors that made the animation stand out. in 3D animation market focused on realistic motion and rendering techniques can have positive implications in terms of expanding animation diversity. This study is expected to be used as academic or research data for researchers studying new production techniques in related fields.

The diversity of spider communities was investigated in the pine forest of Pinus densiflora in Songri-san, where chemical pesticides had been applied to control pine gall midge (Thecodiplosis japonensis). Spider communities were surveyed in four areas: a pesticide-untreated natural forest (area A), a forest with vinyl-covered ground surface (area B), an aldicarb-treated forest (area C) and a forest treated with a systemic pesticide (phosphamidon) (area D). A total of 74 spider species from 17 families were collected from the four survey areas. There were 54 species from 15 families in area A, 27 species from 12 families in area B, 29 species from 9 families in area C and 34 species from 9 families in area D, respectively. The species diversity of spider communities was highest in pesticide-untreated area A, and much lower in the other three areas. The monthly species diversity of spider communities was highest in May and lowest in January. The similarity of the spider communities was highest in areas B and D. The monthly similarity of the spider communities was highest in November and February. The dominant species was Clubiona jucunda (12.71%, N=304 individuals). According to our results, the application of aldicarb and phosphamidon dramatically decreased spider diversity and the number of individuals in the forests. Thus, the application of these two pesticides to natural forests should be restricted, or alternative pesticides need to be developed. Our results also indicated that application of the pesticides should be avoided in May and June when high spider diversity is expected.

The spider of a drum washing machine receives the repeated fatigue loadings during laundering. Although the spider is designed statically safely, it often happens fatigue failure. Therefore it requires the safe design for fatigue and needs the prediction of quantitative fatigue life. The S-N diagram for a spider material is developed by fatigue test and statistical analysis. The stresses are measured directly from strain gages on the spider. To predict the fatigue life of spider, the rainflow counting method and Miner's rule are used. The data for fatigue life are analyzed statistically. From these data, reliability estimation for fatigue life can be done and also, equivalent fatigue life can be obtained. It will be applied to make and improve to a short period for design and prototype test.

Bernard $Dadi{\acute{e}}$ expresses virtue, justice, and goodness by mixing reality and fiction through the life of the spider Kacou $Ananz{\grave{e}}$ in The Black Cloth (le Pagne noir). In Black Africa folktale, especially $Co{\hat{o}}te$ d'Ivoire, virtue, justice, and goodness are important factors. The spider's life is full of imagination and tricks that reveal a variety of lessons: i) material abundance and frustration in the 'Spider and the Tortoise', ii) an autistic life that refuses to separate from the mother in the 'Spider's Hump', iii) leaving a trace of violating the taboo on the sheep in the 'Spider's Ox', iv) the failure of a ploy by hurting others to satisfy individual desire in 'The Dowry'. These diverse stories enable us to understand human characteristics and imperfections by questioning customs of society and value of customs, reinterpreting folktale, and clarifying instructional intentions.
