Spiders play a vital role in agricultural ecosystems by capturing and preying on small insects, thereby controlling the pests around crops. However, without directly collecting the specimen, it is challenging to accurately determine the species of the spider that formed the web and its diet. Spiders dissolve their prey with digestive fluids while consuming; thus, leaving very little residue in their digestive system. This study aimed to identify the spider that formed the web and the prey caught in the web using environmental DNA (eDNA) present in the spider web. For this purpose, eDNA using the mitochondrial cytochrome C oxidase subunit I (COI) gene was extracted from five adjacent spider webs collected from residences near agricultural environments. Based on the genes extracted from spider webs, it was confirmed that the most commonly found gene in all five spider webs was COI of Parasteatoda tepidariorum, and no other spider genes were detected. Among the five spider webs, prey was found in only one web, and in that web, genes of arthropods other than spiders were detected. The genes of the prey found in the spider web were identified to be those of Orthocladius tamarutilus, Tanytarsus tamagotoi, and Yemma exilis. Thus, without directly collecting arthropod specimens from the spider web, it was possible to identify the spider and its prey. This provides crucial information that can help in clearly understanding the predatory activities of spiders in agricultural ecosystems in the future.

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.

주파수 위상 간섭계를 이용한 전기장 재구성 방법(SPIDER)을 이용하여 Kerr 렌즈 모드록킹된 티타늄 사파이어 레이저 공진기에서 생성된 펨토초 영역의 극초단 펄스의 펄스폭과 위상을 측정하였다. 8cm 길이의 SF10 매질과 마이켈슨형의 시간지연암(arm)을사용하여 주파수 층밀림(shearing)을 구현하고 제2종 BBO결정으로 합주파수 발생을 시켜 SPIDER 장치를 구성 하였다 얻어진 층밀림 주파수 간섭 신호로부터 SPIDER 알고리즘을 이용하여 펄스의 전기장을 복원하였다 SPIDER의 정확도를 확인하기 위해 SPIDER에서 얻은 펄스로 재구성한 간섭형 자체상솬신호를 직접 측정한 간섭형 자체상관 신호와 비교하였다. SPIDER를 티타늄 사파이어 레이저 공진기에 적용하여 19fs의 펄스폭을 얻었으며 sech$^2$나 가우시안으로 가정한 간섭형 자체상관의 결과는 이보다 작은 값으로 나타나서 펨토초 레이저의 정확한 펄스폭 측정을 위해서는 펄스모양의 가정이 필요없는 SPIDER 방법이 필요함을 알 수 있었다.

미국의 애니메이션 제작사인 픽사(Pixar)에서 제작된 <토이 스토리 Toy story>(1995) 1편 이래로 3D 애니메이션은 사실적인 움직임과 렌더링 기법을 지향해 왔다. 하지만 2018년에 개봉한 <스파이더맨 뉴 유니버스 Spider man : into the spider-verse>는 일러스트 기법을 통해 구현된 독특한 배경과 수작업을 통해 제작된 듯한 캐릭터의 역동적인 움직임을 통해 기존의 3D 애니메이션과는 많은 차이점을 보여주며 좋은 평가를 받았다. 본 연구에서는 <스파이더맨 뉴 유니버스>에서 구현된 특유의 스타일을 중심으로, 새로운 제작기법과 표현법에 대해 만화책 같은 아트 스타일과 그 이외에 애니메이션의 완성도를 높이는데 기여한 효과로 두 가지 영역으로 분류해 분석을 진행했다. 만화책 같은 스타일에서는 다시 첫째, 수작업 느낌을 도와주는 효과, 둘째, 만화적인 FX 디자인, 셋째, 코믹스 기법을 직접 활용한 예로 나누었고, 두 번째 영역은 첫째, 독특한 애니메이션 스타일, 둘째, 캐릭터별 다른 렌더링 기법, 셋째, 특유의 편집 스타일로 분류하였다. 기존 할리우드의 다소 정형화된 스타일의 3D 애니메이션 시장에서의 <스파이더맨 뉴 유니버스>는 애니메이션의 다양성 및 예술적 표현의 확장이라는 측면에서 긍정적인 의미를 부여할 수 있다고 판단되며, 본 연구는 관련 분야에서 새로운 제작기법과 표현법을 연구하는 연구자들에게 기초 학술자료나 연구자료로 활용될 수 있을 것으로 생각한다.

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.
