Agricultural extension services in YoungDong county, ChungBuk province have tried and changed many things to overcome difficult situations since localization of extension services in 1997. The county Rural Guidance Office changed the name of the office as county Agricultural Technology & Extension Center (ATEC), and has been operated as a service center for all people who need help in agriculture. The recent efforts of the ATEC have been placed on eco-friendly agriculture and sustainable agriculture for protecting the natural environment of the county as well as production of safe agricultural products. In order to overcame difficult situations under the IMF, the ATEC has tried to find new ways for the extension services because of reduced extension educators under the IMF restructuring. The followings were a few examples of many efforts in various fields to overcome difficult situations in the rural county; 1) The ATEC has supported services to produce safe and high quality agricultural products and to increase their high value through extension services for food processing. 2) The ATEC has opened experimental fields for farmers who want to learn new technologies to cultivate grapes, persimmons, apples and pests etc., specialty fruit trees in the county. 3) The ATEC has implemented many kinds of programs to improve the quality of the extension educators to serve better.

The current exploratory study attempted to investigate the influence of environment-friendly agricultural products(EAPs) perception on EAPs consumption behavior. The survey was conducted to parents of elementary school in Chung-buk area by the help of homeroom teachers of each school. Out of 500 questionnaires administered, a total of 305 completed questionnaires were returned, yielding a response rate of 61%. Regarding buying behavior, 89.6% of respondents have ever bought EAPs, among them, 52.9% usually bought in a mart. The reason to buy EAPs was mostly safety(57.6%), nutrition & health(30.4%), and quality(7.0%). The 11 items representing the attitude and knowledge were analyzed, resulting in three distinct dimensions-'attitude', 'knowledge', and 'concern'. The knowledge level of EAPs was slightly higher than medium. Concerning the influence of EAPs perception on EAPs consumption behavior, the more having high knowledge and attitude level on EAPs, the more lead to the EAPs consumption behavior. This implicit the importance of education to enhance the knowledge level and positive attitude towards EAPs.

To assess the potential of peanut sprouts as a functional food material, the germination rate, resveratrol content, and nutritional components of sprouts were analyzed. Of all samples tested, Gyeong-buk peanuts had the highest germination rate. The resveratrol content was higher in peanuts than in peanut sprouts. The resveratrol level in Gyeong-buk peanut sprout ($15.5{\mu}g/g$) was the greatest of all tested samples. The cotyledon of Gyeong-buk peanut sprout had the highest resveratrol content ($24.89{\mu}g/g$), followed by the roots ($12.66{\mu}g/g$), but resveratrol was not detected in the stems. The levels of moisture, crude protein, crude fat, ash, and carbohydrate in Gyeong-buk peanut sprout were 6.69%, 35.58%, 33.08%, 2.96%, and 21.96% (all w/w), respectively, in dried material. Compared with peanuts, peanut sprouts contained higher protein levels, and a lower content of crude fat, but showed a minimal difference in mineral content. The amino acid content of peanut sprouts (2,551.8 mg/100 g) was higher than that of peanuts (87.89 mg/100 g). Specifically, the asparagine content of peanut sprouts (834.54 mg/100 g) was the highest of all amino acids. Saturated fatty acids, including myristic and palmitic acids, were detected in peanuts, and the levels of unsaturated fatty acids such as oleic (31.19 g/100 g) and linoleic acids (39.24 g/100 g) in peanut sprouts were higher than those of other fatty acids.

Embryos formed in vivo were collected from 171 donors housed in Chung Cheong Buk-Do Institute of Livestock and Veterinary Research of the Chungbuk community during the years 2009~2012. We evaluated annual embryo collection, effect of follicle stimulating hormone (FSH), controlled internal drug release (CIDR) and prostaglandin (PG) administration to the donor for superovulation and controlling the estrus cycle, seasonal effects of embryo collection and compared the number of embryos recovered as per the collection days and pregnancy rate. In all, 1,243 embryos were collected from 118 donors with an average of $7.31{\pm}5.35$ embryos per donor, out of which 69.4% were transferable. Dosages of FSH required for inducing superovulation in various donors were compared. Average number of embryos collected from donors administered with 30 AU of FSH ($7.13{\pm}5.74$ per donor) was not significantly different from that of donors who were given an injection of 24 AU of FSH ($7.53{\pm}4.91$ per donor). However, the percentage of transferable embryos in the 30AU FSH-administered group (63.2 %, 449 of 711) was higher than that in the 24AU FSH-administered group (77.8%, 414 of 532). In the group of donors under a natural estrus cycle, the FSH dose administered did not influence the number of transferable embryos produced ($7.49{\pm}6.25$ per donor for 30 AU of FSH vs $7.49{\pm}4.92$ per donor for 24 AU of FSH). However, in donors administered with CIDR and PG for controlling the estrus cycle, the FSH dose affected the average number of transferable embryos collected ($4.25{\pm}2.87$ per donor for 30 AU of FSH vs $8.50{\pm}6.36$ per donor for 24 AU of FSH). We collected embryos from donors 6, 7 or 8 days after artificial insemination (AI). Results showed that the percentage of transferable embryos among those collected 8 days after AI was significantly higher than that among embryos collected 6 or 7 days after AI. Seasonal variations did not affect number of recovered embryos and pregnancy rates in natural estrus cycle and CIDR treatment groups (48.28% and 42.55%) but higher than pregnancy rate of frozen embryos (19.63%). These results indicated that administration of FSH beyond a threshold dose (at least 24 AU) has no beneficial effect on the production embryos and that collection of embryos 7~8 days after AI is optimal for embryo recovery. CIDR treatment induced superovulation in short term and had no influence on the natural estrus cycle. Finally, although good-quality embryos were transferred, freezing significantly reduced the pregnancy rates after transfer.

Heugu (Korea Black Cattle) is one of the indigenous cattle breeds in Korea; however there has been severe lack of genomic studies on the breed. In this study, we report the first whole genome resequencing of Heugu at higher sequence coverage using Illumina HiSeq 2000 platform. More than 153.6 Giga base pairs sequence was obtained, of which 97% of the reads were mapped to the bovine reference sequence assembly (UMD 3.1). The number of non-redundantly mapped sequence reads corresponds to approximately 28.9-fold coverage across the genome. From these data, we identified a total of over six million single nucleotide polymorphisms (SNPs), of which 29.4% were found to be novel using the single nucleotide polymorphism database build 137. Extensive annotation was performed on all the detected SNPs, showing that most of SNPs were located in intergenic regions (70.7%), which is well corresponded with previous studies. Of the total SNPs, we identified substantial numbers of non-synonymous SNPs (13,979) in 5,999 genes, which could potentially affect meat quality traits in cattle. These results provide genome-wide SNPs that can serve as useful genetic tools and as candidates in searches for phenotype-altering DNA difference implicated with meat quality traits in cattle. The importance of this study can be further pronounced with the first whole genome sequencing of the valuable local genetic resource to be used in further genomic comparison studies with diverse cattle breeds.

To analyze the genetic relationships among 23 accessions of Asparagus cochinensis $L_{OUR}$, random amplified polymorphic DNA(RAPD) analysis was performed using artificially synthesized 10 primers. The range of polymorphism was $42.9{\sim}91.7%$ with an average of 72.9% in 85 randomly and specifically amplified DNA fragments. On the. basis of similarity coefficient analysis by unweighed pairgroup method, arithmetic average method(UPGMA), 23 accessions of Asparagus cochinensis $L_{OUR}$ could be classified into 6 groups at the similarity coefficient value of 0.82. Group I contained 5 accessions, Group II contained 6 accessions, Group III contained 6 accessions, GroupIV contained 2 accessions, Group V contained 2 accessions and Group VI contained 2 accessions. The range of total genetic similarity coefficient value of 23 accessions of Asparagus cochinchinensis $L_{OUR}$ was $0.47{\sim}0.92$ and average value was 0.76. To obtain more exact data from PCR, we also tried to develope enhanced RAPD techniques using Bovine Lacto Transfer Technique Optimizer(BLOTTO). In RAPD analysis of Asparagus cochinensis $L_{OUR}$, we could obtain better RAPD results by adding BLOTTO at a final concentration of 1%.

This study was conducted to investigate potential effects of previously identified QTL regions on carcass traits in Hanwoo. The data analyzed in this study was collected from 326 steers of 67 proven sire. Thirteen micorsatellite markers spanning QTL regions on bovine chromosomes 1 and 14 were genotyped in 326 steers. The following breeding values were analyzed for QTL effects. Cold carcass weight breeding value (CCWBV), longissimus muscle area breeding value (LMABV), marbling score breeding value (MSBV) and backfat thickness breeding value (BFTBV). Chi-square tests were performed to compare frequencies of individual allele between high and low breeding value groups. Significant differences of allele frequencies in BMS711, MCM130, BMS4049, and BMS2263 were found. And also, in RM180, BL1029, BM4305, and BMS2055 there were significant differencies of allele frequencies. These results showed a potential application for investigation of putative QTL locations.
