Generally, the phase control dimmer has been widely used due to simple interface and easy handling. However, the electrical characteristics are not good for the method in which the phase control dimmer cuts the input voltage. This paper has researched about DALI(Digital Addressable Lighting Interface) controller, that is the digital lighting control method, and implemented DALI protocol satisfied with the IEC-62386 standard. In addition, the existing phase control dimmer was used as the controller of DALI and not only individual control but also group control was possible. And the performance was proved to be good by applying our theory to 30[W] LED lighting control system.

Salvador Dali put a title of his work as 'A Propos of the Treatise on Cubic Form by Juan de Herrera' at 1960. Through this work which is consisted in cube frame surrounding black and white letter squares and nails in the sky, he directly referred about the cube which were showed in his pictures. To understand the meaning of this work, Dali's paintings and Juan de Herrera's design and architectural ideas are analysed by building. His concerning about absolute existence like god and nuclear takes the cubic form by Juan de Herrera instead of pictorial tendencies of Cubism, however pictorial elements such as sky and nails were still used in the work. He use alphabet letter as pattern consisting wall and symbol representing 'Juan de Herrera', moreover number '2' is taken to show up line attribute. Dali had several design develop process, and finally he reached an new stage called 'Hypercube'. Hypercube can distinguish from Cubism and Herrera's architectural idea, and it will be free from objective world based in Euclid geometry. Although cubic is the simplest shape. It can contain the variety of developments in these fields - philosophy, architecture, painting and etc.- from Platon to nuclear physics and coexists in a picture of Salvador Dali.

This study suggests method of expression of nail art utilizing Salvador Dali's Paranoiac Critical Method and produced the actual works based on discussions on Salvador Dali's painting, Paranoiac Critical Method, Nail Art's artistry and technique of expression. The result of the study is as follows: 1) Characteristic of Dali's painting is a Paranoiac Critical Method. If suggesting this characteristic in a method of expression of nail art, a good work which can be expressed on a small space, a nail, representing Dali is selected and 5 tips which are very similar to the rate of the painting are used in order to obtain an aesthetic effect just like a painting. And after composing on tips using the whole paining or part of painting, actual techniques of expression such as Hand Painting, Protranse or Water Decal are used. 2) the result of nail art produced utilizing Dali's Paranoiac Critical Method is as follows. Most of all, for nail art I with the topic of "The Persistence of Memory" (1931), after giving changes to 5 tips for the watch which is a part of the painting, Hand Painting technique is used using Acrylic Painting with colors which are similar colors to the painting. Then for nail art II which adopted "Slave Market with Invisible Bust of Voltaire" (1940), the whole painting is divided into 5 tips and Protranse technique which attaches printed paper onto nails was used. Lastly, for nail art III with the subject of "The Enigma of Desire My Mother, My Mother, My Mother" (1929), Water Decal which is emphasizing the parts of the painting and composing on 5 tips and copying printed picture onto Water Transfer Paper in order to attach on the nails is used. These nail arts show aesthetic characteristics such as fantasy, unconsciousness, grotesque, infinity, non-realism and horror just like paintings.

This paper is to illustrate the infestation and related ecological characteristics of chigger mites on the Asian house rat (Rattus tanezumi). A total of 17,221 chigger mites were collected from 2,761 R. tanezumi rats, and then identified as 131 species and 19 genera in 2 families. Leptotrombidium deliense, the most powerful vector of scrub typhus in China, was the first major dominant species on R. tanezumi. All the dominant mite species were of an aggregated distribution among different individuals of R. tanezumi. The species composition and infestations of chiggers on R. tanezumi varied along different geographical regions, habitats and altitudes. The species-abundance distribution of the chigger mite community was successfully fitted and the theoretical curve equation was ${\hat{S}}(R)={37e^{-(0.28R)}}^2$. The total chigger species on R. tanezumi were estimated to be 199 species or 234 species, and this further suggested that R. tanezumi has a great potential to harbor abundant species of chigger mites. The results of the species-plot relationship indicated that the chig-ger mite community on R. tanezumi in Yunnan was an uneven community with very high heterogeneity. Wide geographi-cal regions with large host samples are recommended in the investigations of chigger mites.

Balamuthia mandrillaris amebic encephalitis (BAE) can cause a fatal condition if diagnosis is delayed or effective treatment is lacking. Patients with BAE have been previously reported in 12 provinces of China, with skin lesions being the primary symptom and encephalitis developing after several years. However, a significantly lower number of cases has been reported in Southwest China. Here we report an aggressive BAE case of a 64-year-old woman farmer with a history of skin lesions on her left hand. She was admitted to our hospital due to symptoms of dizziness, headache, cough, vomiting, and gait instability. She was initially diagnosed with syphilitic meningoencephalitis and received a variety of empirical treatment that failed to improve her symptoms. Finally, she was diagnosed with BAE combined with amebic pneumonia using next-generation sequencing (NGS), qRT-PCR, sequence analysis, and imaging studies. She died approximately 3 weeks after the onset. This case highlights that the rapid development of encephalitis can be a prominent clinical manifestation of Balamuthia mandrillaris infection.

Based on the field investigations in 91 investigation sites (counties) in southwest China between 2001 and 2019, the present paper reported the chigger mites on A. agrarius mice in southwest China for the first time by using a series of statistical methods. From 715 striped field mice captured in 28 of 91 investigated sites, only 255 chiggers were collected, and they were identified as 14 species, 6 genera in 3 subfamilies under 2 families. Of 715 A. agrarius mice, only 24 of them were infested with chigger mites with low overall prevalence (P_M=3.4%), overall mean abundance (M_A=0.36 mites/host) and overall mean intensity (M_I=10.63 mites/host). The species diversity and infestation of chiggers on A. agrarius were much lower than those previously reported on some other rodents in southwest China. On a certain species of rodent, A. agrarius mouse in southwest China seems to have a very low susceptibility to chigger infestations than in other geographical regions. Of 14 chigger species, there were 3 dominant species, Leptotrombidium sialkotense, L. rupestre and Schoengastiella novoconfuciana, which were of aggregated distribution among different individuals of A. agrarius hosts. L. sialkotense, one of 6 main vectors of scrub typhus in China, was the first dominant on A. agrarius. The species similarity of chigger mites on male and female hosts was low with C_SS=0.25, and this reflects the sex-bias of different genders of A. agrarius mice in harboring different chigger species.

Chigger mites are the vector of scrub typhus. This study estimates the infestation status and ecological characteristics of chiggers on the chestnut white-bellied rat Niviventer fulvescens in Southwest China between 2001 and 2019. Chiggers were identified under the microscope, and infestation indices were calculated. The Preston's log-normal model was used to fit the curve of species abundance distribution. A total of 6,557 chiggers were collected in 136 of 342 N. fulvescens rats, showing high overall infestation indices (prevalence=39.8%, mean abundance=19.2, mean intensity=48.2) and high species diversity (S=100, H'=3.0). Leptotrombidium cangjiangense, Neotrombicula japonica, and Ascoschoengastia sifanga were the three dominant chigger species (constituent ratio=42.9%; 2,736/6,384) and exhibited an aggregated distribution among different rat individuals. We identified 100 chigger species, with 3 of them (Leptotrombidium scutellare, Leptotrombidium wenense, and Leptotrombidium deliense) as the main vectors of scrub typhus in China and nine species as potential vectors of this disease. Disease vector occurrence on N. fulvescens may increase the risk of spreading scrub typhus from rats to humans. Chigger infestation on N. fulvescens varied significantly in different environments. The species abundance distribution showed a log-normal distribution pattern. The estimated number of chigger species on N. fulvescens was 126 species.

색채는 중요한 시각적 요소로서 도시 이미지와 사람들의 인식 형성에 중요한 영향을 미친다. 도시환경에서 색채를 정량적으로 분석하는 작업은 복잡한 과정을 필요로 하여 과거에는 실행하기가 어려웠다. 그러나 최근 머신 러닝 기술의 급속한 발전으로 관광객이 공유한 사진을 이용하여 도시 색채를 분석하는 것이 가능해졌다. 본 연구는 중국의 인기 관광지인 대리시를 사례로 선정하여 관광객이 공유한 대리시의 사진을 수집하였으며, 머신 러닝 기술을 결합하여 대규모 도시 색채를 측정하는 방법을 탐색하였다. 구체적으로는 먼저 DeepLabv3+ 모델을 사용하여 ADE20k 데이터 셋을 기반으로 관광객이 공유한 사진의 의미 분할을 수행하여 사진에서 인공 요소를 분리했다. 다음으로 K-means 클러스터링 알고리즘을 사용하여 대리시의 인공 요소의 주요 색상을 추출하고, 이러한 색상 간의 상관관계를 분석하기 위해 인접 매트릭스를 구축했다. 연구 결과에 따르면 대리시의 인공 요소의 주요 색상은 주황-회색이 가장 높은 비율을 차지한다. 또한, 회색 계열의 색상이 다른 색상과 자주 조합되어 사용되는 경향이 있다. 분석에 따르면 대리시의 인공 요소의 색채 특성은 지역의 민족 문화와 불교 문화의 영향을 받는 것으로 나타났다. 본 연구는 색채 분석을 위한 새로운 접근 방법을 제공하며, 연구 결과는 대리시가 관광객의 기대에 부합하는 도시 색채 이미지를 형성하는 데 도움이 될 뿐만 아니라 향후 대리시의 색채 계획을 위한 참고 자료를 제공하고자 한다.
