The carrier materials used for the development of bacterial inoculants to be effective in field were made with various carrier materials of two major forms, alginate bead and powder inoculants. Inoculants were prepared after mixing those carrier materials with Pseudomonas fluorescens SSL3 and Bacillus subtilis B5, and the treatment effects of each inoculants was investigated on cucumber, tomato, pepper and potato. Survival density of SSL3 and B5 in various carrier materials for duration of storage and the bead inoculants were better than the powder. In the powders, survival rate increased in carrier materials treated 5% skimilk. The growth condition of microorganisms in carrier materials is good at powder. When they were preserved in the long period, contamination is problem. Scanning(200 to 600nm) of the P. fluorescens SSL3 supernatant in centrifuged MKB broth incubated for 48h had two main peaks, pyochelin(300nm) and pyoverdin(400nm). The potato yield in field experiments of spring, treated with bead formulas showed increase of 22~29% in whole potato breeds as compared with control, because the bead formulas degraded, and released the antibiotic microorganisms in slow and constant rate. In the pot experiment, there were significant difference in soil, wheatbran, and bead formed wheatbran.

Cephalometric superimposition is unable to evaluate tooth movement along the occlusal plane and the errors of photographing and superimposition of the occlusogram is also inevitable. The purpose of the present study was to evaluate the rotational movements of the maxillary posterior teeth following space closure after extraction of maxillary first premolars. using 3D dental images. In 19 adult females. analysis of rotational movements of the maxillary posterior teeth was performed between the initial and final 3D dental images superimposed on the maxillary hard palate. The results showed a diversity of rotational movements of posterior teeth. The causes of various rotational movements may be different rotation of molars in each case at the beginning of treatment. individual characters of the dental arch and tooth morphology. The results of the study indicate that accurate evaluation of rotational movements of posterior teeth following space closure after extraction of premolars using 3D dental images can be obtained through the subdivision of tooth movement during the initial aligning, space closure and finishing stages.

The loss of posterior support and the abnormal jaw relation can cause pathologic findings. If deep bite patients with multiple missing teeth, can not have the stable posterior contact, the mandible moves posteriorly, and consequently the overjet and overbite get worse. And when the mandibular irregular occlusal plane is corrected, it is easier to have the bilateral balanced occlusion with the maxilla. So the treatment goal is to give proper posetrior support and establish appropriate anterior guidance, and ultimately provide improved mastication and esthetics recovery. In this case, a 68 year old man, having deep bite without posterior support was evaluated by the vertical dimesion decision flow-chart. An available prosthetic height, anterior occlusal relation such as overjet, overbite and the esthetic part such as facial height and the cephalometric analysis are the factors to be considered.

Three species of the yeast Saccharomyces cerevisiae, Humicola grisea and Candida glabrata were assumed as microbial inoculants for fermentation of rice straw silage. Four types of silage innoculated with three yeasts including control (non-treatment) were opened on day 1, 3, 6, 9, 15 and 20 after ensiling, and analyzed for fermentation status (pH, crude protein, microbial counts) and the microbial population attached with silage texture using SEM (Scanning Electron Microscopy). The results obtained were summarized as fallow; The pH of silage juice was decreased to 4.3 after 6th day of fermentation in the treatments innoculated with yeast, but was not changed at the ranges of 5.47 to 5.67 in control. Crude protein concentration of silage was increased by 38～41% with yeast inoculation compared to control. From SEM observation, it could be confirmed that crude protein concentration of silage was increased by microbial growth and SCP synthesis. The yeast Saccharomyces cerevisiae and Candida glabrata could be used as useful fermenters of rice straw silage.

One of the most important things to analyze model ground test in plane strain is to observe deformation, accurately, In this paper, the analyzing method of ground deformation by using photos of points on membrane attached on transparent acryle plate of side wall of model ground box is described. First order 4-node isoparametric elements are used to calculate strains of ole cents.

Three species of the linyphiid genus Walckenaeria, Walckenaeria chikunii Saito and Ono, 2001, Walckenaeria furcillata (Menge, 1869), and Walckenaeria ichifusaensis Saito and Ono, 2001, are reported new to the Korean spider fauna. W. furcillata is widely distributed throughout the Palearctic region, but W. chikunii and W. ichifusaensis are only known from their type localities in Japan. Photographs and illustrations of the diagnostic characters are provided.

This paper presents the features for quantitative evaluation of medical images based on the technique of image processing. In consideration of advice from medical doctor, 1 derive three features seemed to be strongly correlated with the degree of disease's advance. From comparison between each feature and evaluation value by medical doctor, our research shows that three features can be a useful aids in quantitative evaluation of lung's disease on chest X-ray images.

Because of computer developing, the digital image making the use of many a field of application with - web-above, electronic publishing. printing, dynamic image management and photo CD production etc., however many problems of save and management. The management image use of compression moth which don't have a affect on image, reduce file size. A study used sequential DCT0based mode and progressive DCT-based mode of JPEG(Joing Photographic Experts Group) compression method and Wavelet compression method. Therefore, the analog image and digital image was changed and applied by several stages according to compression rate. It made inquiries of the optimum compression rate that be compared quality transformation between original image and compressed image. As compression image was printing simply, the quality was studied by subjective valuation method, that was studied propriety and usefulness.

전국 어디서나 쉽게 볼 수 있는 참나무류는 가을이면 우리에게 정성스러운 열매를 도토리라는 정겨운 이름으로 우리에게 돌려준다. 그리고 우리 조상들의 예로부터 도토리를 슬기롭게 이용하여 와KT고, 야생동물의 긴요한 식량으로 사용되어, 자연을 풍요롭고 아름답게 만드는 슬기로운 산물이다. 자연을 표방하는 기획물 사진에는 다람쥐가 도토리를 먹고 있는 모습이 대표되는 한 장면이기도 하다. 우리나라 전국어디서나 신갈나무, 갈참나무, 떡갈나무, 굴참나무, 상수리나무, 졸참나무 등 많은 참나무류가 분포하여 가을이면 단풍의 극치를 이루기도 한다. 이들이 만들어내는 종자에 해충이 탐을 내어 우리의 정서를 빼앗고 있다 대표적인 것이 요즘 등산로나 산책로를 따라 가면 길 위에 많이 떨어져 있는 참나무류 가지들의 피해는 도토리거우벌레의 피해이다. 마치 톱으로 참나무가지를 잘라 떨어뜨리는 모습은 자연의 신비가 오묘하다는 것을 말해 주기도 한다. 구과에 알을 낳고는 가지를 주둥이로 잘라서 떨어뜨려 어린자식이 도토리를 먹고는 쉽게 땅속에서 들어갈 수 있게 하는 것이다. 참나무류 도토리를 직접 가해하는 몇몇 해충에 대한 생태 및 방제법을 간략하게 소개하고자 한다.

Nowadays, owing to the diffusion of smartphones and the growth of social networking services (SNS), the number of people who share their life with other SNS users by posting photos is increasing. The number of Instagram users has been particularly increasing since Instagram started its service in 2010. Compared to other SNS such as Facebook and Twitter, Instagram runs its service by focusing solely on photos, which is a major differentiation factor compared with other existing SNS. Previous studies, however, do not examine SNS that focus on photo sharing adequately. Therefore, we establish a hypothesis relating to the motivations behind a user's photo sharing attitude and posting intention through Instagram. Moreover, this will be achieved by employing TRA(Theory of Reasoned Action) and focusing on intrinsic and extrinsic motivations. The analysis results show that intrinsic motivation influences a user's sharing attitude and subjective norms. Apart from this, Instagram's expressivity influences a user's photo sharing attitude and posting intention.
