This study was deal with the development of breed-specific DNA marker which is able to identify Hanwoo and European cattle breeds(Non-Hanwoo) meat. Genetic differentiation between Korean cattle(Hanwoo) and European cattle breeds was examined by Random Amplified Polymorphic DNA(RAPD) analysis. The RAPD patterns were identical among Non-Hanwoo, such as Holstein, Hereford, Aberdeen Angus, Brown Swiss, Limousin or Simmental, but the above pattern was different from that of Hanwoo. All bands detected in the Hanwoo samples were observed in Non-Hanwoo cattle samples, but one of the common bands found in samples was not detected in the Hanwoo samples. The band(1.4kb) may be useful as a marker for identifying a meat of Hanwoo from imported cattle meat. Actually, the detection of the DNA marker was tested by DNA analysis with 929 samples which were prepared from bloods of 673 Hanwoo cattles and 141 Holstein cattles, from 115 imported cattle meats. The DNA marker was absent in 644 of 673 Hanwoo cattles (96%) but present in 245 of 256 Non-Hanwoo cattles (95%). These results show that the DNA marker is effective to characterize Hanwoo and Non-Hanwoo meat by its detection. This DNA marker, however, was not useful in detecting unwanted crossbreeding between two cattle breeds, because the band pattern in hybrid cattle shows one of two band patterns in Hanwoo and Non-Hanwoo.

탁 트인 언덕, 따스한 햇볕, 푸른 하늘과 상쾌한 바람이 불어오는 곳. 이곳은 <천우축산>이다. 고향인 이곳, 곡성에서 노후를 보내고 싶었던 박희애 (55), 임차택 (58) 대표는 광주에서 전기기술자로 근무하다가 2005년에 겸업으로 축산을 시작했다. 두 대표에게 축산 비결을 묻자 그저 남들하고 똑같이 키운다고 대답한다. 그럴 리 없다. 한우 축산 영인의 일상에서 그 노하우를 살펴보자.

최근 제조 기업들의 가장 큰 화두 중 하나는 제품과 서비스의 통합이다. 그간 제품과 서비스 통합과 관련한 다양한 개념들이 제시되어 왔으나, 정의 및 유형에 대한 보편적인 프레임워크가 존재하지 않는다. 본 연구에서는 제품과 서비스의 통합에 관련된 다양한 개념들을 아우르는 포괄적인 용어 (umbrella term)로써 통합 제품-서비스(integrated product-service: IPS)를 제시한다. 기존 문헌 연구를 통해 IPS 관련 기존 개념들을 개괄하고, 이들을 Product/service fusion과 Product/service Convergence의 두 가지로 분류한다. 다음으로 IPS를 유형화하기 위한 분류체계(typology)로써 IPS 큐브(cube)를 제시한다. IPS 큐브는 통합의 형태(pattern), 원천(origin), 기술(technology)의 세 가지 차원으로 구성되며, 각 차원이 모두 세 가지 유형으로 구분되기 때문에, IPS 큐브는 27개의 셀로 이루어진 정육면체 형태를 띤다. 각 셀은 고유한 IPS 유형을 나타내며, 각 셀에 해당하는 실제 IPS 사례들이 제시된다. 본 연구에서 제시한 IPS 큐브는 유형별 IPS 개발을 위한 전략, 프로세스, 방법론을 개발하는데 있어서 유용한 시사점을 제공해줄 수 있다.

Human emotions are expressed in various ways. It can be expressed through language, facial expression and gestures. In particular, the facial expression contains many information about human emotion. These vague human emotion appear not in single emotion, but in combination of various emotion. This paper proposes a emotional expression algorithm using Active Appearance Model(AAM) and Fuzz k- Nearest Neighbor which give facial expression in similar with vague human emotion. Applying Mahalanobis distance on the center class, determine inclusion level between center class and each class. Also following inclusion level, appear intensity of emotion. Our emotion recognition system can recognize a complex emotion using Fuzzy k-NN classifier.

The purpose of this study is to produce wanted sex progeny of genetically confined White Hanwoo (albinism) with preselected sex sperm. One bull of White Hanwoo was chosen for semen donor and X sperm was sorted by MoFlo XDP cell sorter. To compare the pregnancy and birth rates, KPN straw was used as control, total number of unsorted sperm was $20{\times}10^6/straw$. Sexed X frozen semen with $20{\times}10^6$ cells or $4{\times}10^6$ cells per straw were in seminated twice on Hanwoo heifers. The abnormality of the sexed X semen was $24.9{\pm}7.31%$ and distal reflex abnormality of mid piece was significantly (p<0.05) higher (11.7%) compared with that of KPN 768 (5.6%). There were no differences on the pregnancy and birth rates between $2{\times}10^6$ cells or $4{\times}10^6$ cells of X-sperm but KPN semen showed significant differences (p<0.05). The pregnancy rates of KPN 768, $2{\times}10^6$ cells and $4{\times}10^6$ cells X-sperm of White Hanwoo cattle were 85.0%, 26.3% and 50%. The birth rates were 80.0%, 15.8% and 21.4%, respectively. The female offspring rates of KPN 768, $2{\times}10^6$ cells and $4{\times}10^6$ cells X-sperm of White Hanwoo cattle were 43.8%, 100% and 100% (p<0.05). These results indicated that sex sorted White Hanwoo could be used for the production of wanted progeny with $2{\times}10^6$ cells/straw for AI. To increase the efficiency of calf production, the sperm number of sex sorted semen will be optimized for sex selection of White Hanwoo progeny.

In-vitro fertilized Hanwoo embryos were biopsied for sex determination by PCR. Biopsied embryos were incubated for 1∼2 hours for the recovery. Those sexed Hanwoo embryos were transferred to 49 Hanwoo and 16 Holstein recipients from February 2000 to February 2001. Of 65 recipients, 14 cows(12 Hanwoo and 2 Holstein) delivered the same offspring as sex-determined by PCR, therefore the conception rate was 21.5%. 1. Total 65 embryos(male 35, female 30) were transferred to recipients, and 14 calves (male 6, female 8) were delivered. In comparison between sex by PCR method and sex of calves born after embryo transfer, the accuracy of sex determination was 100.0%. 2. The conception rate after transfer with biopsied embryo between Hanwoo and Holstein was 24.5% and 12.5% 3. The conception rate after transfer with biopsied embryo between fresh and frozen-thawed embryos was 23.5% and 14.3%. 4. The conception rate according to the season when embryo was transferred was 11.8, 29.4, 23.5 and 20.0% for spring, summer, autumn and winter, respectively. 5. The conception rate according to embryo quality after biopsy was 41.7, 30.0 and 0.0% for excellent, good and fair quality. 6. The conception rate according to thickness of uterine horn was 71.4, 18.9, 11.8 and 0.0% for 0, +, ++ and +++ thickness. 7. The conception rate according to the site in the uterine hem where embryo was put was 30.0, 20.0 and 10.0% for cranial, mid, and caudal part of uterine horn. 8. The conception rate according to the quality of corpus luteum ipsilateral to the uterine horn where embryos was transferred was 41.2, 14.3 and 15.4% for excellent, good and fair quality. 9. The conception rate according to the time required for embryo transfer was 18.2, 30.0, 30.0, 0.0 and 25.0% for 10, 15, 20, 25 and 30 minutes. 10. The conception rate according to parity of recipients was 26.5, 19.1, 14.3 and 0.0% for the primiparous, the 2nd parous, the 3rd parous and the 4th parous recipients. These results indicated that fresh embryos are more demanded than frozen-thawed embryos for good conception rate in embryo transfer with biopsied-sexed embryo. Also, it was indicated that we should consider embryo-recovering condition, recipient's uterine thickness, transfer site in uterine horn, quality of corpus luteum, time required for transfer and parity of recipient to achieve good conception rate in ET with biopsied-sexed embryos.

Recently, augmented reality and virtual reality in the ICT sector have been highlighted. So also interested in related HMD areas to facilitate contact with the VR content is being attend. This paper proposes a method for implementing to the virtual reality through the mobile HMD device with the real time 360 image. This system is required the real time 360 image streaming server configuration and image processing for augmented reality and virtual reality. The configuration of the streaming server is configured the DB server to store images and the relay server that can relay images to other devices. Augmented image processing module is composed based on markerless tracking, and there are four modules that are recognition, tracking, detecting and learning module. Also, the purpose of this paper is shown the augmented 360 image processing through the Mobile HMD.
