Asymptomatic carriage of Clostridioides difficile in pet shop puppies
Yuya Kimura(Yuya Kimura ),Satoshi Kameshima(Satoshi Kameshima ),Naoyuki Itoh(Naoyuki Itoh ) 한국예방수의학회 2023 예방수의학회지 Vol.47 No.2
Crowded pet shops can become infected with various pathogens. Although dog carriers of Clostridioides difficile tend to be asymptomatic, the toxigenic strains sometimes cause gastrointestinal symptoms in humans. The present study was conducted to determine the infection rate of C. difficile in pet shops. The feces of 137 dogs younger than one year of age, collected from four pet shops, were assessed by culture and PCR. Carriage rates of C. difficile in dogs aged ≤90, 91-180, and ≥181 day-old were 12.2% (10/82, 95% confidence interval: 6.0-21.3%), 0.0% (0/42, 95% confidence interval: 0.0-8.4%), and 7.7% (1/13, 95% confidence interval: 0.2-36.0%), respectively. Five C. difficile isolates carried genes encoding toxins A and B, while the remaining isolates contained only toxin B. However, none of the C. difficile carriers had diarrhea. These results highlight the necessity of promoting adequate hygiene precautions in pet shops to prevent infection by C. difficile.

<P>Microcrystals of ErBa<SUB>2</SUB>Cu<SUB>4</SUB>O<SUB>8</SUB> suspended in a liquid medium were triaxially aligned by a frequency-modulated magnetic field and allowed a free rotational relaxation after the magnetic field was turned off. In situ X-ray diffraction measurements of the suspension were performed during relaxation, and the temporal change of the orientation fluctuation was monitored via broadening of the diffraction spots. The rotational diffusion constants were determined using the plot of the orientation fluctuation versus the elapsed time of rotational relaxation. The diffusion constants thus determined were in close agreement with those evaluated by the Stokes law but showed slight anisotropy, indicating that the microcrystals studied had shape anisotropy. The present method can provide a useful means for experimentally determining rotational diffusion constants of microcrystals suspended in viscous media. This paper shows that, due to the combination of the initial triaxial alignment and the subsequent monitoring of the relaxation process by means of X-ray diffraction, the diffusion constants along arbitrary crystallographic axes are determined separately.</P> [FIG OMISSION]</BR>
Application of silk composite to decorative laminate
Kimura, Teruo,Aoki, Shinpei The Korean Society for Composite Materials 2007 Advanced composite materials Vol.16 No.4
Recently, natural fiber reinforced composite is attracting attention and considered as an environmentally friendly material. Usually cellulosic fibers are used to reinforce the composites, but some protein fibers such as silk and wool serve the same purpose. In this paper, we proposed a method of producing artistic composite from artistic fabric by using silk fiber reinforced biodegradable plastic, which is designated as 'silk composite', for reinforcement. In order to expand applications of the silk composite, we performed the compression molding of decorative laminates with woody material, which was selected as a core material, and examined the properties of molded decorative laminates with various content of the silk composite. Since plywood and medium-density fiberboard (MDF) are widely used for decorative laminates, we selected them as core materials. As a result, flexible decorative laminates with high flexural strength were obtained by compounding the silk composite with wood materials.
The Possibility and Prospects of Northeast Asian Integration : From the Japanese Perspective
Kimura, Fukunari 한국비교경제학회 2002 비교경제연구 Vol.9 No.2
Imagine the world in the year of 2015. Europe would expand the geographical coverage of deep integration. North America and Latin America would form FTAA(Free Trade Area of Americas), and even TAFTA(Trans-Atlantic Free Trade Area) could be concluded. Then what would happen in East Asia? The move of Korea and Japan in the coming few years will be very crucial for the future of economic integration in East Asia. Korea and Japan can establish a more equal-footing relationship than ever and have responsibility in maintaining economic dynamism of the region. The author hopes that the NAIS movement becomes a big step forward in the direction of regional integration. We cannot envisage, however, that a deep integration including all the economies in Northeast Asia will be immediately realized. We mut develop tighter communications with each other and go forward step by step. In this regard, it seems natural to initiate regional integration with the Korea-Japan FTA.
異文化コミュニケ?ション入門書のディスコ?ス : 「自己開示」に?する記述に着目して
Kimura Arinobu(木村有伸) 韓國外國語大學校 外國學綜合硏究센터 日本硏究所 2015 日本硏究 Vol.0 No.64
본 원고에서는 문화 비교 접근인 이문화 커뮤니케이션(ICC)론에서 문화나 문화의 차이에 대해 이야기 하는 점을 문제로 들기 위해 ICC입문서 중 「자기표출」에 관한 기술을 분석했다. 그 결과, 미국과 일본의 자기표출 정도에 관한 조사결과가 ICC입문서에서도 다뤄지고 있는 점, 그리고 그 자기표출의 차이를 설명 할 때에 문화 비교 접근이 주류였던 1990년대 이전뿐만이 아니라, 비교적 최근의 입문서에서도 문화차이를 강조하는 이항대립개념이나 인과명제를 게시하는 방법이 사용된 점을 확인했다. 이렇게 인과명제가 많이 쓰이는 것은 문화간의 차이를 강조할 뿐만이 아니라, 문화적인 고정관념을 만들어내는 것이다. 본 원고에서는 문화 차이에 대한 이러한 언설이 ICC입문서에서 반복적으로 사용되어 온 점은 학습자가 이문화를 이해하는 것을 방해해왔다고 비판했다. Although the validity of academic discourse that emphasizes cultural differences has been challenged, it has been shown that in academic arguments, this belief remains strong. Therefore, this study examines several introductions of intercultural communication that adopt a cultural comparison approach and demonstrate the continuity of such a belief. This study also analyzes the discourse regarding "self-disclosure" in these introductions. First, it demonstrates that 19 out of 34 books focus on the concept of self-disclosure. Second, it shows that the authors of these introductions often use dichotomy between two cultures and causal propositions in order to emphasize the difference of self-disclosure between Japanese and American individuals. However, since various approaches, such as these introductions, include a methodological problem (i.e., a lack of comparison), it is remarkable that hypothetical descriptions based on such scarce supporting evidence are still quoted as academic propositions.
