There is increasing interest in exploiting natural products as feed additives to solve problems in animal nutrition and livestock production. Essential oils and saponins are two types of plant secondary compounds that hold promise as natural feed additives for ruminants. This paper describes recent advances in research into these additives. The research has generally concentrated on protein metabolism. Dietary essential oils caused rates of NH$_3$ production from amino acids in ruminal fluid taken from sheep and cattle receiving the oils to decrease, yet proteinase and peptidase activities were unchanged. Hyper-ammonia-producing (HAP) bacteria were the most sensitive of ruminal bacteria to essential oils in pure culture. Essential oils also slowed colonisation and digestion of some feedstuffs. Ruminobacter amylophilus may be a key organism in mediating these effects. Saponin-containing plants and their extracts appear to be useful as a means of suppressing the bacteriolytic activity of rumen ciliate protozoa and thereby enhancing total microbial protein flow from the rumen. The effects of some saponins seems to be transient, which may stem from the hydrolysis of saponins to their corresponding sapogenin aglycones, which are much less toxic to protozoa. Saponins also have selective antibacterial effects which may prove useful in, for example, controlling starch digestion. These studies illustrate that plant secondary compounds, of which essential oils and saponins comprise a small proportion, have great potential as 'natural' manipulators of rumen fermentation, to the potential benefit of the farmer and the environment.

Background A patient's overall condition sometimes does not allow for the complete removal of a dead eschar or injured slough in cases involving a pressure-injury skin lesion. This frequently occurs in clinical practice, particularly in bedridden and older patients receiving home care or intensive care. Even after debridement, it is also difficult to manage open exudative wounds in these patients. Nevertheless, when a mature or immature eschar is treated without proper debridement, liquefaction necrosis underneath the eschar or slough tends to reveal a large, open wound with infectious exudates. We hypothesized that if the presence of any bacteria under the eschar can be evaluated and the progression of the presumed infection of the subeschar can be halted or delayed without creating an open wound, the final wound can be small, shallow, and uninfected. Methods Using a punch instrument, we performed 34 viable subeschar tissue cultures with a secure junction between the eschar and the normal skin. Results The bacterial study had 29 positive results. Based on these results and the patient's status, appropriate antibiotics could be selected and administered. The use of suitable antibiotics led to relatively shallow and small exposed wounds. Conclusions This procedure could be used to detect potentially pathogenic bacteria hidden under black or yellow eschars. Since subeschar infections are often accompanied by multidrug-resistant bacteria, the early detection of hidden infections and the use of appropriate antibiotics are expected to be helpful to patients.

The drone technology, which is receiving a lot of attention due to the 4th industrial revolution, requires an Unmanned Aerial Vehicles'(UAVs) flight path search algorithm for automatic operation and driver assistance. Various studies related to flight path prediction and recommendation algorithms are being actively conducted, and many studies using the A-Star algorithm are typically performed. In this paper, we propose an Optimal 3D Flight Path Recommendation System for unmanned aerial vehicles. The proposed system was implemented and simulated in Unity 3D, and by indicating the meaning of the route using three different colors, such as planned route, the recommended route, and the current route were compared each other. And obstacle response experiments were conducted to cope with bad weather. It is expected that the proposed system will provide an improved user experience compared to the existing system through accurate and real-time adaptive path prediction in a 3D mixed reality environment.

Japanese Give and Receive Verbs are divided into "YARU", "MORAU" and "KURERU". These are influenced by the subject, speaker's viewpoint and meaning. Three verbs are used in a different way depending on who is the giver and who is the taker. I analyze "YARU" and "KURERU" Verbs used in TOUSEISYOUSEIKATAGI. It focus on politeness, gender, and meaning when combined with 'TE'. As an expression of politeness, 'Yaru' is to give to a person of lower social status or an animal or plant. 'Ageru' is to give to an equal ora person of lower social status nowadays. However, 'Ageru' which is treated as elegance of the language remained expression of respect, 'Yaru' is used when the receiver is a person of lower social status and equal social status in TOUSEISYOUSEIKATAGI. 'Kureru' is used when the receiver is a person of lower social status and equal social status, 'kudasaru' is used when a person of higher social status gives the speaker something in TOUSEISYOUSEIKATAGI. Women speakers use 'oyarinasai' 'oyariyo' 'ageru' 'okureru' and men speakers use 'yaru' 'kureru'. Speech patterns peculiar to men are 'kuretamae' 'kurenka'. If the verbs are joined to "TE", they obtain abstract meaning as well as a movement of things. They express some modality for action of the preceeding verbs. The modality has the following meanings ; good will, goodness, benefits, kindness, hopeness, expectation, disadvantage, injury, ill will and sarcasm. In addition, 'TE YARU' expresses the speaker's strong will, 'TE KURERU' expresses the speaker's request.

Robot ALICE@ERICA is a service robot developed to receive donations and to provide information services. ALICE@ERICA stands for Artificial Learning Intelligence robot for Culture and Entertainment at ERICA. In order to achieve the specific purpose of receiving donations, proper appearance design, appropriate movement and good communication skills are required in terms of HRI. In this paper, we introduce three strategies for developing robots to receive donations effectively. The first is to design a robot that makes people feel intimacy, the second is to approach only one of several people as a donor, and finally the donor communicates with video contents and voice recognition. A survey was conducted on the person who showed the reaction after the robot donated money in public places. Based on the survey results, it is proved that the method presented in this study effectively contributed to fund raising. If robots can perform actions that require high level of HRI, such as donation, robots can contribute more to human society. We hope that this study contributes to the improvement of human happiness.

노(能)는 일본을 대표하는 전통연극으로 불교, 신도(神道), 수험도(修驗道)와 같은 종교사상을 배경으로 하여 성립하였다. 이 중에서도 중세시대에 널리 확산되어 있던 수험도로부터 받은 영향은 현저하다. 수험도라는 종교사상을 배경으로 성립한 대표적인 노가<다니코(곡행(谷行))>이다. <다니코>의 내용 분석을 통해 중세의 수험문화, 특히 산악수행자인 야마부시(산복(山伏))의 수행의 단면을 엿볼 수 있다는 점에서 이 곡이 갖는 가치는 매우 크다. 본고에서는 이제까지의 <다니코>의 선행연구에서 간과되어 왔던 야마부시의 수행에 초점을 두고 수험도의 세계관이 노에 있어서 어떤 방식으로 극화되었는지를 구체적으로 살펴보았다. 동시에 다니코에 있어서의 아쟈리와 동자의 관계에 착목하여 중세문화의 특징이라 할 수 있는 치고(치아(稚児))문화의 투영이라는 새로운 해석을 시도하였다. 노<다니코>는 소년 와카마츠(약송(若松))가 어머니의 병환치유를 위해 스승을 쫓아 가즈라키산(갈성산(葛城山))에 입산하여 수행하던 차에 병에 걸리자, 야마부시 일행에 의해 '다니코(곡행(谷行))'를 당하게 되었지만, 결국에는 야마부시 일행의 기도로 다시 소생한다는 이야기이다. 다니코는 병든 수행자를 계곡에 던지고 그 위에 토사나 돌을 덮어 산채로 매장하는 형법을 말한다. 노<다니코>의 제목도 바로 이 수험도의 형법에서 유래한 것이다.<다니코>는 수험도의 역사를 배경으로 하여 야마부시의 수행과 행법·와카마츠의 효심·치고 문화 등을 크로스 시키면서 일본중세의 사회문화의 특징을 조화롭게 담아낸 작품이다. 가혹한 형법을 소재로 하여 난행과 고행의 연속인 야마부시의 입산수행의 어려움을 리얼하게 표현하고 있어 당시의 입산수행의 단면을 엿볼 수 있다. 수험도의 본질인 입산수행은 생명의 재생, 생명의 탄생을 의미하며, 심산에서의 고행을 통해 새로운 탄생에 이른다고 관념되어 왔다. 이러한 수험도를 이끌어 온 것은 산악수행에 의해 신령스런 힘을 획득한 야마부시라고 할 수 있다. 그들의 활동은 산에 한정되지 않고, 사토(리(里))에 있어서의 서민의 신앙과도 깊게 관련되어 있었기 때문에 수험도는 일본의 민속·문화의 특징을 찾는데 있어서 불가결의 요소라고 할 수 있다. 가혹한 다니코 형법에 의해 자칫 유쾌하지 않은 인상으로 끝나버릴 작품이었지만, 소생이라는 대반전을 통해 효심에 의한 미담을 담은 노로 분위기가 전환되었다. 작가가 설정한 와카마츠의 소생이라는 극적효과는 본래 수험도가 본질적으로 추구하고 있었던 재탄생의 구조에서 힌트를 얻은 것으로 보인다. 한편, 이제까지 노<다니코>에 있어서의 스승 아쟈리와 와카마츠의 관계를 치고 문화와 관련시켜 지적한 논문은 없었다. 이 작품의 어느 부분에서도 '치고'라는 단어를 쓰지 않았지만, 중세의 관객들은 당시에 만연했던 치고 문화에 대한 이해 하에 아쟈리와 와카마츠가 치고 관계라는 공통된 인식을 가지고 있었을 것이다. 노를 온전히 이해하기 위해서는 당시의 사회적 종교적 문화의 기반에 대한 이해가 선행되어야 한다.

개인의 정원을 대중에게 오픈하게끔 장려하는 법률상 개념인 '민간정원'은 2015년 관련법이 지정된 이후 2019년 11월, 25개의 민간정원이 산림청에 등록되어 있다. 정원문화 확산 및 장려라는 측면에서는 긍정적인 제도이지만, 그 정확한 성격 및 역할이나 지정요건 등에 대해 충분한 공론을 거친 것은 아닌 상태이다. 본 연구는 현재 전국에 지정되어 있는 민간정원 25개소의 현황 실태 분석을 통해 민간정원이 갖고 있는 특성을 분석하고자 하였다. 연구 결과, 민간정원의 지역적 분포에서 남부지방이 많은 비중을 차지하고 있었고, 이는 자연적, 기후적 조건의 영향이었다고 판단되었다. 그리고 그 외에도 해당 지자체의 정책기조, 담당공무원의 재량 등의 영향으로 좌우되기도 하였다. 또, 민간정원에 속하는 정원은 거의 현대에 만들어진 정원들이 많았고, 유일하게 1개소가 조선시대부터 내려온 고택정원이었다. 민간정원 소유자들은 50~80대로, 처음에는 정원이 좋아서 시작했다가 커진 정원의 관리를 감당하기 어려워 경제적 지원에 대한 기대감으로 민간정원을 통한 외부 개방을 하거나 지역활성화에 의지가 있는 경우도 있었다. 또한, 정원 이외의 수익시설로 이윤을 창출하기도 하였는데, 일부는 관련 프로그램을 운영하며 정원문화 확산을 도모했다. 향후 지속가능한 민간정원 제도를 위해서는 등록 기준에 대한 점검이 필요하고, 지역 내에서 수행할 뚜렷한 역할 정립이 필요하다고 판단되었다. 또한 관리 및 마케팅을 위한 차후 방안이 필요하다. 본 연구는 아직 체계화 되지 않은 민간정원 제도에 대한 기초연구로 의의가 있다.
