  • Real-time quantitative PCR (qRT-PCR) is one of the important methods for investigating the changes in mRNA expression levels in cells and tissues. Selection of the proper reference genes is very important when calibrating the results of real-time quantitative PCR. Studies on the selection of reference genes in goat tissues are limited, despite the economic importance of their meat and dairy products. We used real-time quantitative PCR to detect the expression levels of eight reference gene candidates (18S, TBP, HMBS, YWHAZ, ACTB, HPRT1, GAPDH and EEF1A2) in ten tissues types sourced from Boer goats. The optimal reference gene combination was selected according to the results determined by geNorm, NormFinder and Bestkeeper software packages. The analyses showed that tissue is an important variability factor in genes expression stability. When all tissues were considered, 18S, TBP and HMBS is the optimal reference combination for calibrating quantitative PCR analysis of gene expression from goat tissues. Dividing data set by tissues, ACTB was the most stable in stomach, small intestine and ovary, 18S in heart and spleen, HMBS in uterus and lung, TBP in liver, HPRT1 in kidney and GAPDH in muscle. Overall, this study provided valuable information about the goat reference genes that can be used in order to perform a proper normalisation when relative quantification by qRT-PCR studies is undertaken.

  • The purposes of this study were to deter-mine the dimensions of the housewives' cloth-ing behavior for the environmental protection and the identify the effective variables. The results of this study was intended to provide fundamental material for the establishment of clothing behavior guidelines for the environmental protection. This study was conducted by reference analysis and empirical study. To develop theoreti-cal framework study. To develop theoreti-cal framework of dimensions of environmental protection behavior, references concerned were analyzed. The results of reference analy-sis showed that the dimensions of environmental protection bahavior were resource and energy saving, sold waste reduction, resource reuse or recycle, and green product purchase. The dimensions of housewives' clothing behavior for environmental protection were identified by use of self-administered questionnaires. The results of enpirical study showed that the dimensions of clothing behavior for the environmental protection wre clothing resource reuse or recycle, clothing management resource saving, clothing consumption resource saving, green product purchase, and clothing management resource saving was the highest and that of resource reuse or recycle was the lowest. Environmental consciousness, taking environmental education or not, residing place, clothing seperate-collectiong at residing place were effective variables on clothing behavior for environmental protection.

  • In this paper I will seek to show that situation theoretic analysis of the attitudes can finely describe references of definite descriptions in attitude reports: co-reference, mis-reference, and speaker's reference. Situation theoretic concepts of a proposition and a resource situation provide excellent means to account for these references: Proposition, which is the combination of a type and an assignment, can combine linguistic and non-linguistic information; Resource situation, sometimes realized as speaker's wrong knowledge situation about an individual, can serve to explain idiosyncratic aspects of attitude reports.

  • The objectives of this study were to examine how the consciousness of resource saving affects the resource-saving behaviors of urban employed wives and to induce their rational resource-saving behaviors by identifying related variables. This study also analyzed some correlations between the resource-saving consciousness and behaviors of urban employed wives to provide basic information for laying the foundations of a green growth culture. The subjects of this study were selected from among employed wives living in the urban areas of Seoul and Gyeonggi-do area. The study was conducted from June 11 to August 7, 2011. A total of 620 questionnaires were collected, and 592 of them were used in the analysis. Data was analyzed via the SPSS 18.0 program to calculate frequencies, mean and standard variation, Cronbach's ${\alpha}$, t-test, ANOVA, Pearson's correlation, hierarchical, and multiple regression analysis. A positive correlation was observed between the resource-saving consciousness and behaviors of urban employed wives. That is, their resource-saving behavior was higher their consciousness of resource saving was high. Furthermore, the most influential variables affecting the resource-saving behaviors of urban employed wives were: the subjects' job type, with specialist or office work; reference groups, such as family, relatives, and neighbors; and low levels of conspicuous consumption habits. Among the variables, the influence of reference groups had the highest explanatory power.

  • In this study, the algorithm of optimal parameter inference is proposed. At this inferring method, we tried to acquire the follow-up to reference pattern through comparing the plant output pattern with random reference pattern. As an inference method, the fuzzy theory was applied and the proposed algorithm was proved by computer simulation.

  • This study seeks to present an option for including a variety of information resources in a reference linking service system. Discussion on reference linking service in journals began in 1999 and applied to real systems, but linking to research papers and patent registers has more recently emerged. This study further suggests that system construction include various information resources such as books and dissertations. This paper also presents principles and prerequisites that should be considered essential when building such systems, including expansion of resources and media formats, development of identifiers on every sort of information resource, linking methods to existing DB, publication revolution and managing copyright-holders, use and improvement of OPACs, and building perfect authority DB.

  • To determine the wind turbine class in the offshore of the Korean Peninsula, the reference wind speed for a 50-y return period at the hub height of a wind turbine was estimated using the reanalysis data sets. The most recent reanalysis data, ERA5, showed the highest correlation coefficient (R) of 0.82 with the wind speed measured by the Southwest offshore meteorological tower. However, most of the reanaysis data sets except CFSR underestimated the annual maximum wind speed. The gust factor of converting the 1 h-average into the 10 min-average wind speed was 1.03, which is the same as the WMO reference, using several meteorological towers and lidar measurements. Because the period, frequency, and path of typhoons invading the Korean Peninsula has been changing owing to the climate effect, significant differences occurred in the estimation of the extreme wind speed. Depending on the past data period and length, the extreme wind speed differed by more than 30% and the extreme wind speed decreased as the data period became longer. Finally, a reference wind speed map around the Korean Peninsula was drawn using the data of the last 10 years at the general hub-height of 100 m above the sea level.

  • The accurate wind speed information at the hub height of a wind turbine is very essential to the exact estimation of the wind turbine power performance testing. Several methods on the site calibration, which is a technique to estimate the wind speed at the wind turbine's hub height based on the measured wind data using a reference meteorological mast, are introduced. A site calibration result and the wind resource assessment for the Taekwanryung test site are presented using a one-month wind data from a reference meteorological mast and a temporal mast installed at the site of wind turbine. From this analysis, it turns out that the current location of the reference meteorological mast is wrongly determined, and the self-developed codes for the site calibration are working properly. Besides, an analysis on the uncertainty allocation for the wind speed correction using site calibration is performed.
