This study was conducted to survey of Ehrlichia (E.) canis and Borrelia (B.) burgdorferi antibodies among clinically healthy German shepherd dogs (116 females and 120 males) using a ELISA kit (SNAP 3Dx; IDEXX Laboratories, USA) in Korea. Whole blood samples are collected from the 236 dogs and are tested to detect E. canis and B. burgdorferi antibodies by using ELISA kit (SNAP 3Dx; IDEXX Laboratories, USA). Confidence interval comparisions revealed that dogs of 4-6 years have higher prevalence with a seropositive result (CI=0.17-0.45) in E. canis than the other age groups but there are no differences among age groups in B. burgdorferi. Also, no differences with a seropositive result were found among different regions in E. canis and B. burgdorferi antibodies. In conclusion, this study was the first large scale survey of canine E. canis and B. burgdorferi antibodies in Korea and provide an useful reference for clinicians.

Up to now, practical engineers applying simplicity value of rockfall block weight suggested in design manual without considering in-situ rockfall block weight which reflect joint characteristics. However, the size of rockfall block varies with joint spacing of discontinuities and influences over rockfall analysis results. In this paper, we estimate realistic rockfall block weight distribution using statistical invariances of joint spacing derived from scan-line survey result. And, we study whether this distribution is applicable in practical rockfall analysis directly. As the results of this study, rockfall analysis results that using rockfall block weight distribution estimated from scan-line survey show resonable and realistic outcomes.

The aim of study is examining the marketing strategies and analyzes space design which is reflected marketing strategy and design elements by coffee shop chains. For the purpose, field survey and the questionnaire survey are conducted in coffee shop chains in Myeong-dong in Seoul. The results of the questionnaire survey are analyzed through SPSS 18.0 program and these results compare with the field survey. The result of analysis were as follows; 1) The company have to plan the coffee shop chains which were reflected by consumer opinion. 2) The coffee shop chains have to plan independent atmosphere space for take out consumers. 3) The coffee shop chains have to consider suitable design elements according to condition of lease, an area and position. 4) The coffee shop chains have to have design marketing strategies which were reflected by space, furniture, color and lighting. 5) Companies should communicate with consumers actively.

The study was designed to forecast and derive future core technologies using Delphi method in Korea agriculture. The technologies will make agriculture for core and strategic industry that has high value-added in 21 century. Questions were given to specialists by each technology in order to survey importance, realization time, level of R＆D in Korea and foremost country, leading group of R＆D, effective policy, etc. for each technology. The target of the survey for Delphi is confined specialists in the area of Bioystems Engineering. 55 core technologies were derived and 31 specialists answered the survey.

Purpose - This paper proposes measurement models to evaluate the management performance of small and medium-sized retail businesses on the basis of a trading area analysis that compares their proposed revenue to actual revenue in the trading area. Research design, data, methodology - The study proposes measurement models consisting of five stages, namely: (1) district background survey, (2) customer survey, (3) competitor survey, (4) business district survey, and (5) business performance analysis. Results - To identify business districts easily, this study preferred a minor-adjusted method based on the Euclidean distance, as it is simple to employ for the small and medium-sized businesses. This model was applied to select coffee shops in Daejeon. Results indicated that although the targeted shop was not located in an appropriate location, actual sales were higher than expected. Conclusions - Small- or medium-sized retail businesses face difficulties regarding the economies of scale and brand recognition and must choose an appropriate location to ensure management stability. However, such businesses will find it difficult to evaluate their competitive edge accurately using a trading area analysis.

Green Frame is a column-beam system that uses composite precast concrete members. Previous studies have proven this system to be not only structurally safe, constructible, and economically feasible, but also environmentally-friendly. If the computerized program is used to estimate the quantity, the result of it shall be calculated much easily, quickly and exactly than manual estimation, because precast concrete members of Green Frame has standard size and connection method between it. Therefore, this study suggest quantity survey concept for column-beam structure comprised of composite precast concrete members. Hereafter, the quantity survey of Green Frame shall be much quickly and accurate, if the system would be made based on the result of this study.

Recently not even government polices but small town decisions are based on the survey data/information, so the most of government agencies/organizations demand various sample surveys in each fields for more detail information. However in conducting the sample survey, nonresponse problem rises very often and it becomes a major issue on judging the accuracy of survey. For that matters, one solution ran be using the administration data. However unfortunately most of administration data are restricted to the common users. The other solution can be the imputation. Therefore several method, of imputation are studied in various fields. In this study, in stead of the simple regression imputation method which is commonly used, factor score regression method is applied specially to the incomplete data which have the unit and item misting values in survey data. Here for simulation study, Consumer Expenditure Surveys in Korea are used.

This paper reports the Survey results from a field monitoring study of office occupancy densities. The field measurement of a office in Yongin was carried out from 19 September to 30 September 2011. The survey has an aim to reveal the building energy consumption relationship between occupancy densities of a realistic office and the previous studies. The results showed that hourly occupied density of the previous studies is more higher than a field survey. we investigated the effects of difference occupancy densities on annual heating and cooling energy consumption using EnergyPlus. Heating and cooling consumption was raised because of the increased occupancy density. therefore, accurately measure the occupnacy schedule is important in order to reduce excessive building energy consumption, and is an significant element to be considered in the energy simulation.

Galaxy clusters, the largest gravitationally bound systems, are an important means to place constraints on cosmological models and study the evolution and formation of galaxies and their large scale distribution. We report results from our study of galaxy clusters in the European Large Area ISO Survey North1(ELAIS-N1) field, covering a sky area of 8.75 $deg^2$. We combine multi-wavelength data from the UKIRT Infrared Deep Sky Survey Deep Extragalactic Survey (UKIDSS DXS, JK bands), Spitzer Wise-area InfraRed Extragalactic survey (SWIRE, Optical-Infrared bands), and CFHT (z band). The photometric redshifts are derived from these datasets and are used to search for high redshift galaxy cluster candidates. Finally, we provide new candidates of galaxy clusters at redshifts 1.0

The purpose of this study is the investigation of the physically handicapped childrens' residentical life, using furniture and opinion of auxiliary furniture ot find out alternative forms of desirable furniture. This study consists of two parts: a survey of residential life and furniture usage and a new chair design based on the survey. Documentary research, observational investigation and questionaire survey methods were used. According to the survey, a chair was chosen as the most needed piece of furniture. The alternative chair was designed to accomodate to the individual physical needs of each child. The structural charasteristics of the chair form consist of four parts: 1) basic seat 2) supporting metal frame 3) detachable chair legs 4) detachable table top. Auxilliary options include adjustable parts such as a head rest, seat belt, arm rest and pedestal.
