In order to the excellent differentiation of syndromes, we study on the individual characteristic factor by the inspection of face colour and tongue & the auscultation and olfaction. To the subject of diagnosis special books and diagnostics textbook of korean medicine, we arrange the individual characteristic factor by the inspection of face colour and tongue & the auscultation and olfaction. The inspection on the individual characteristic factor was analyzed the face colour, inspection of tongue. The auscultation and olfaction on the individual characteristic factor was analyzed the 25 types by the five-voice (五音) in Huang Di Nei Jing (黃帝內經). As the results, the individual characteristic factor is very important item of the four methods of diagnosis and the differentiation of syndromes. And Therefore the process on four methods of diagnosis and differentiation of syndromesis is necessary to divide the signs of individual characteristic factor and the signs of disease.

Although upper respiratory tract infections (URTIs) are common diseases, there have been no studies of their relationship with the indices obtained from tongue image analyses. The purpose of this study was to identify a tongue index through an analysis of tongue images (TIs) showing significant changes before and after treatment in patients with URTIs. A computerized tongue image acquisition system was developed to acquire TIs from subjects in the same environment. An image was taken from each of 39 URTI patients and 39 healthy controls. For the patients, images were acquired before and after treatment to identify changes. The tongue area was classified into a tongue body and a tongue coating, and the coating ratio between the two areas, the average value of the colour of each area, and teeth marks were calculated. No significant difference was observed in age or sex between the URTI patients and control participants. Heart rates were slightly different. The analysis of TIs showed that the luminance of the tongue coating and the coating area ratio were decreased, while the reddish value of the tongue body at the centre area increased as the treatment progressed. Tongue coating and body in URTIs had different colour and shape from those in the normal. It is expected that this result will contribute not only to the objectification of traditional Chinese medicine but also to diagnostic methods that do not involve face-to-face physician visit during the pandemic.

철근 콘크리트 구조물에서의 염화물 침투에 따른 구조물의 열화는 주요한 문제로 이와 관련하여 현재까지 많은 연구들이 수행되고 있다. 콘크리트 구조물의 염화물 침투에 있어서 염화물 확산 이외에도 염화물 흡수에 의한 침투도 고려되어야 하며, 구조물의 사용기간 중에 발생되는 균열은 염화물 침투의 주 경로가 될 수 있기 때문에 이러한 변수들이 구조물의 내구성능 평가에 고려되어야 한다. 본 연구에서는 철근 콘크리트에 두 가지 균열 폭 (0.1 mm, 0.3 mm)을 발생 시킨 후, 염화물 흡수 실험을 실시하였다. 염화물 흡수 실험으로부터 흡수에 따른 무게 변화와 AgNO3 용액을 이용한 변색법으로 균열면에서의 염화물 침투 정도를 확인하였다. 변색 범위를 이용한 이미지 분석 또한 실시하였다. 흡수 시간 및 균열 폭이 증가하면 염화물 흡수량이 증가하는 것을 확인 하였다. 모든 균열 폭에서 1 시간 이내에 염화물이 철근 깊이까지 도달하였다. 또한 철근 계면을 통한 염화물 이동 가능성을 확인하였으며, 이는 철근 부식의 주요한 원인으로 작용할 수 있어 추가적인 실험을 통한 검증이 필요할 것으로 판단된다.

Today, crops face many characteristics/diseases. Insect damage is one of the main characteristics/diseases. Insecticides are not always effective because they can be toxic to some birds. It will also disrupt the natural food chain for animals. A common practice of plant scientists is to visually assess plant damage (leaves, stems) due to disease based on the percentage of disease. Plants suffer from various diseases at any stage of their development. For farmers and agricultural professionals, disease management is a critical issue that requires immediate attention. It requires urgent diagnosis and preventive measures to maintain quality and minimize losses. Many researchers have provided plant disease detection techniques to support rapid disease diagnosis. In this review paper, we mainly focus on artificial intelligence (AI) technology, image processing technology (IP), deep learning technology (DL), vector machine (SVM) technology, the network Convergent neuronal (CNN) content Detailed description of the identification of different types of diseases in tomato and potato plants based on image retrieval technology (CBIR). It also includes the various types of diseases that typically exist in tomato and potato. Content-based Image Retrieval (CBIR) technologies should be used as a supplementary tool to enhance search accuracy by encouraging you to access collections of extra knowledge so that it can be useful. CBIR systems mainly use colour, form, and texture as core features, such that they work on the first level of the lowest level. This is the most sophisticated methods used to diagnose diseases of tomato plants.

This paper is the study on the Medium Designator in Non-book materials. Main contents of this study were as follows; 1. The medium designator serves to indicate the class of material to which an item belongs. This is used to give an 'early warning' ;to the catalogue user. 2. This medium designator may be further divided into two elements ; a general material designation (GMD), for example video-recording, and a specific material designation (SMD), for example, videodisc. 3. GMD: In cataloging, a term indicating the broad class of material to which a bibliographic item belongs, such as 'motion picture', and SMD : In descriptive cataloging, a term indicating the special class of material (usually the class of physical object) to which a biblographic item belongs, such as videocassette. 4. Locating the medium designator after the title proper was not prescribed until ISBD(G) and AACR2. In pre-ISBD(G) codes, the ,early, warning type of medium designator was placed after all title information. But in AACR2, the medium designator is placed after the title proper, but before parellel title and other title information. 5. In Terminology, Two separate lists of designations are given in AACR2, l.1C1, one for British and one for North American use. The British list contains fewer terms, and uses generic categories to group together some of the North American list. 6. The problem of where to place the medium designator might be circumvented by using some kind of early alerting device other than a formal element of biblliographic description. Various alternatives have been suggested. A more popular device is the provision of symbols or 'media code' which are part of the call number and indicate the porticular medium type. 'Colour-coding' the use of used by some libraries but is now longly discouraged. 7. According to Frost. The medium designatorhas been generally reeognized as serving three functions; 1) as a statement of the nature or basic format of the item cataloged and thus as a meant of informing the user as to the type of material at hand; 2) as a description of the physical charaetistics of medium and as a means of alerting the user to equipment needed to make use of the item. 3) as a device to distinguish different physical formats which share the same title. 8. AACR2 raises some problems which decision makers have neet had to face preriously It provides a GMD for every item in the collection including books and it makes the application of any or all GMD's optional.

화재피해 콘크리트 구조물의 안전진단 시, 기존 내구성 평가 방법으로는 고온으로 인한 강도감소 및 재료의 변화 등을 정량화하기가 어렵다. 특히, 두께별 손상도가 다른 공시체의 압축강도를 부재의 압축강도 저하의 대표 값으로 사용하고 있어 콘크리트의 깊이에 따른 손상도 변화를 반영하지 못하고 있다. 이 연구에서는 고온에 노출된 콘크리트의 손상깊이를 정량적으로 평가하기 위하여 400℃-800℃ 온도로 콘크리트 공시체를 전면 가열과 일면 가열 조건으로 가열실험을 수행하였다. 가열 후 전면 가열 공시체의 압축실험과, 일면 가열 공시체를 고온 노출면부터 20mm두께의 절편을 만든 후 각각에 대해 쪼갬 인장실험과 색조분석을 실시하였다. 실험결과, 공시체 절편의 쪼갬 인장강도로부터 산정된 압축강도 감소율이 전면 가열공시체의 압축강도 값과 평균 10% 이내로 나타났고, 색조분석 결과 400℃-600℃에서 빨강 색상, 700℃이상에서는 회색계열로 변색되는 일관적인 색상 값이 관찰된 바, 이 연구에서 제안한 기법은 수열온도의 추정과 콘크리트 잔존 압축강도와 손상깊이를 합리적으로 평가할 수 있는 것으로 나타났다.
