This study was conducted to establish an individual identification system in Hanwoo cattle. Samples of 33 Hanwoo individuals from Korean elite sire families were used. Thirteen major microsatellite markers were selected from alleles amplified, their frequencies, H(Heterozygosity) and PIC(Polymorphism Information Content) with Hardy-Weinberg equilibrium. Next, in order to evaluate the power of the markers selected on the individual animal identification, MP(Match probability) and R(Relatedness coefficient) with the percentage of animal incorrectly identified were computed. Finally nine microsatellite markers were selected and discussed.

In MMORPGs, there are many problems with the Grinding player experience. This research divides the Grinding player experience into four dimensions: Grinding in-Autonomy, Competence, Relatedness and Positive affect through theoretical investigation of game experience. Through the study of Litman (2008), Curiosity is divided into two dimensions, I-Type Curiosity and D-Type Curiosity, and the relationship between Curiosity and Grinding player experience is studied. By distributing questionnaires, collecting data, and using SPSS software to conduct reliability analysis, validity analysis, correlation analysis and multiple regression analysis on the data, it is verified that in MMORPG, I-Type Curiosity can positively affect Grinding in-Autonomy, Competence, Relatedness and Positive affect. D-Type Curiosity can positively affect Grinding in-Autonomy, Competence and Positive affect, but D-Type Curiosity has no statistical relationship with Grinding in-Relatedness. And through the standardized coefficient (Beta) value, between the Curiosity factors, I-Type Curiosity has a greater impact on Grinding in-Autonomy and Positive affect, and D-Type Curiosity has a greater impact on Grinding in-Competence. Finally, from the perspective of I-Type Curiosity and D-Type Curiosity, combined with the drawbacks of the MMORPG Gringding mechanism, some concrete and feasible suggestions and optimization schemes are put forward to improve the Grinding player experience. This research result can provide some feasible suggestions for MMORPG developers and designers, optimize the MMORPG Grinding mechanism from the perspective of I-Type Curiosity and D-Type Curiosity, and improve the Grinding player experience. It can provide appropriate assistance for the improved development of MMORPG games.

The effectiveness of genetic markers on Hanwoo traceability systems was applied and evaluated from Korean 33 Hanwoo elite sire families. Five microsatellite markers were selected finally, which were located on chromosomes different chromosomes with the end sequencing of 100 HW-YUBAC that were recorded in the NCBI by Yeungnam University. Eleven major microsatellite markers were selected from allele amplified, their frequencies, H(Heterozygosity) and PIC(Polymorphism information content) with Hardy-Weinberg equilibrium. Next, in order to evaluate the power of the markers selected on the individual animal identification with experimental condition, the match probability(MP) and the relatedness coefficient(R) were computed.

This paper presents a novel diagnostic method to determine Sasang Consitution (SC) by elasticity coefficient of hand dorsal skin of elderly people. For this purpose, we carried out a clinical test, in which Our SC diagnostic tool and one Oriental medical doctor with SC medicine expertise participated to categorize 458 healthy subjects into four constitutions. After excluding heavy-noise, we extracted 295 subjects' elasticity coefficient feature data and statistically analyzed their SC relevance with ANOVA test. It resulted in that, Taeum-in has high elasticity coefficient compared to Soeum-in in a significance level of 0.05. There are no differences of elasticity coefficient in genders. This result is supported by the theory of Longevity and Life Preservation in Eastern Medicine(Donguisusebowon, 동의수세보원) which suggested that Taeum-in's flesh is solid and Soeum-in's one is tender. This is the first work which reports the relatedness of skin elasticity coefficient and SC by an objective clinical test.

The determination of relatedness between individuals in a family is crucial in analysis of common complex diseases. We present a method to infer close inter-familial relationships based on SNP genotyping data and provide the relationship coefficient of kinship in Korean families. We obtained blood samples from 43 Korean individuals in two families. SNP data was obtained using the Affymetrix Genome-wide Human SNP array 6.0 and the Illumina Human 1M-Duo chip. To measure the kinship coefficient with the SNP genotyping data, we considered all possible pairs of individuals in each family. The genetic distance between two individuals in a pair was determined using the allele sharing distance method. The results show that genetic distance is proportional to the kinship coefficient and that a close degree of kinship can be confirmed with SNP genotyping data. This study represents the first attempt to identify the genetic distance between very closely related individuals.

Five broiler chicken lines, namely HC, BPB2, CPB2, PB2 and UM1, involving in a selection program and differing in selection intensity and genetic background, were screened for randomly amplified polymorphic DNA (RAPD) polymorphism using 10 selected decamer primers. Nine primers amplified the genomic DNA, generating 200 to 2,500 bp and all detected polymorphism between lines. Out of 74 bands scored using these primers, 34 (50.0%) were found to be polymorphic. The number of polymorphic loci ranged from 3 to 6 with an average of 4.33. Lines differed considerably for within-population genetic similarity estimated by band frequency (WS = 93.55 to 99.25). Between-line genetic similarity estimates based on band sharing as well as on band frequency ranged from 71.35 to 86.45 and from 73.38 to 87.68, respectively. Lines HC and PB2 were the most closely related to the other, while BPB2 and CPB2 appeared to be more distant from each other. The between-line genetic distance based on both band sharing and band frequency revealed the similar trends as for Between-line genetic similarity. Based on BS and BF criteria, BPB2 and CPB2 as well as PB2 and UM1 lines can be merged to launch a new genetic group for further progress in biometrical objectives. A phylogenetic tree, derived using Nei's coefficient of similarity revealed the different pattern of genetic distance between lines.

본 연구는 지금까지 보증 및 후보씨수소로 선발된 씨수소에 대하여 연도별 평균 근교 및 혈연계수를 추정하고 씨수소의 유효집단크기를 추정하여 현재 한우개량 체계의 문제를 도출하여 발전된 대안을 제시하고자 실시하였다. 분석에 이용된 자료는 한우개량사업소로부터 1983년부터 2008년까지 1,128두의 당 후대검정 씨수소자료와 한국종축개량협회로부터 3,760두에 대한 혈통자료를 받아 이용하였다. 보증 및 후보씨수소의 평균 근교계수는 0.04에서 0.97%의 분포로 추정되었으며, 평균 혈연계수는 0.10에서 6.82%의 분포로 추정되었다. 유효집단 크기는 1983년부터 2008년까지 26년간 평균 근교비율을 이용하였을 때 220두로 추정되었다. 근교수준은 최근 2년간 급격히 증가하였고, 평균 혈연계수 역시 점차 증가하는 추세이다. 유효집단크기도 최근 5년의 근교비율로 추정하였을 때 47두로 작게 추정되었다. 보증씨수소 선발시 후대검정우의 도체성적에 의한 유전능력평가 자료의 활용뿐만 아니라, 근교 및 혈연계수를 고려하고 한우의 유전적 다양성의 보존과 근교를 피하기 위하여 현행의 보증씨수소 두수를 증가시켜 유효집단크기를 높여야 될 필요성이 있다고 사료된다.
