In this study, we suggest an objective standard in selection of candidate horse mates. Korea Racing Authority provided racing records and pedigree information of 44 sires and 954 dams. The datasets were used to predict Racing Indices represented by the averages of earnings earned by offspring for each dam and sire that indicate the racing performance of its domestic progeny. Proportion of wins and second places to the number of taken races and the mean of distances for the won races of a sire were significant factors in linear model with minimum prediction errors. For dam, those factors were the average of earned money per race, number of outstanding broodmares in pedigree, and the comparable index which indicates the relative affinity with its mate. We can use the resultant model for a horse mate by choosing one of the candidates with the largest predicted value for hypothetical offspring.

본 연구는 대학생의 여가 유형, 스포츠 미디어 이용 정도, 인터넷 스포츠의 이용 정도 및 스포츠 미디어로서 인터넷을 선호하는 선택 요인을 분석하고, 나아가 그 선택 요인이 인터넷 스포츠 소비에 미치는 영향을 규명하는데 그 목적을 두고 있다. 서울 지역의 대학생 412명을 대상으로 설문조사를 실시하였고, 응답이 불성실하다고 판단된 12부를 제외한 400부가 분석에 사용되었다. 분석 결과, 전체적으로 대학생들은 여가 활동으로서 스포츠활동에 가장 많이 참가하는 것으로 나타났고 인터넷 서핑이 그 뒤를 이었다. 하지만, 여가 활동으로서 인터넷 서핑이 여학생과 남학생에서 각각 1, 2위를 차지하였고 여학생의 스포츠 활동은 6위에 머물렀다. 대학생들은 스포츠를 직접 관람하기보다는 직접 참여하거나 미디어를 통하여 스포츠를 접하는 것을 선호하는 경향이 두드러진다. 또한 스포츠를 경험하는 미디어에 있어서는 여전히 TV가 인터넷 보다 우위에 있으나 그 차이는 크지 않았다. 인터넷을 이용한 스포츠 미디어를 선호하는 요인 분석 결과, 정보 수집, 간접 경험, 그리고 접근 용이로 구분되었다. 이 요인들이 인터넷 스포츠 소비에 미치는 영향을 분석한 결과 대학생들은 정보 수집의 용이함 때문에 인터넷 스포츠를 선호하고 이 요인은 인터넷 스포츠 소비에 긍정적인 영향을 미치는 것으로 나타났다. 위의 결과들은 인터넷이 스포츠 미디어의 중요한 소비 영역이라는 것을 보여준다. 따라서 인터넷은 여가 스포츠 산업에서 점점 더 성장하는 새로운 영역이기 때문에 더욱 많은 연구와 투자가 필요하다.

In MANET, the AODV routing protocol with on-demand method has a problem in large control packet overhead. In order to improve this, we first need a comprehensive analysis of correlation between performance metrics and factors affecting the performance of AODV. Selected parameters based on this analysis make it enable to be a more accurate and fair performance analysis, as well as to reduce the time and effort when constructing a scenario for performance analysis. In this paper, various scenarios are configured to apply AODV by varying the values of factors affecting the performance with network simulator QualNet 5.0, and then the results are analysed using performance metrics proposed by IETF MANET working group. This paper also founds a correlation between performance metrics and factors affecting the performance for AODV routing protocol, choosing the values of factors that represent many of the most maximum and minimum values of each performance metrics, and proposes optimal simulation parameters for a more accurate performance evaluation of routing protocols with minimal scenario in experiments. Next, performance comparison of AODV, DSR and DYMO routing protocols based on the proposed simulation parameters is shown which provides a comparative analysis on the performance of on-demand routing protocols. Results of this paper could be very useful for the researcher or service provider who wants to find nice simulation environment or select a proper routing protocol.

The study seeks to identify factors affecting the choice of a university by first-year Business Administration students in Vietnam. Probability sampling is using Stratified sampling of 500 students from five private universities in Ho Chi Minh City surveyed by convenience sampling. This paper employs mixed research methods - measuring Cronbach's Alpha, EFA, Regression and using PATH model - to test the hypotheses of the research model. The results of the study identify five factors: Prestige, Geographical location, Facilities, Attractiveness of the field and Media. All these factors have a positive influence on the standing of the university brand. It means that the higher the Prestige, Geographical location, Facilities, Attractiveness of the field and Media, the higher the university brand. The results indicate that Geographical location is the most influential factor to enhance the private university's brand. Bringing Geographical location is, thus, advisable to enhance a university standing. The brand plays a determining role in students' trust when selecting a university. Media is still the top concern of new students when they choose to study at a university. Media still remains an important consideration for new students when choosing a university. So, this factor should be utilized by universities to enhance their attractiveness.
