최근 웹의 확산과 더불어 제품개발을 위하여 공동작업 구성원들 사이의 정보 공유와 재사용을 지원하는 웹 기반의 공동작업 지원 시스템 개발에 대한 관심이 고조되고 있다. 기업 및 공공기관의 공동작업은 광범위하게 분산되어 있는 경우가 많으며, 여러 작업그룹 내의 구성원은 이러한 환경에서 효과적으로 서로의 정보를 교환하고 공유할 수 있는 작업공간을 필요로 한다 또한 공동작업의 결과로서 생성된 기술문서의 체계적인 관리 기능과 실시간 의사전달의 기능 등이 함께 제공되는 것이 바람직하다. 본 논문에서는 웹 기반의 공동작업 지원 시스템인 CoWare의 설계와 구현에 대하여 설명한다. CoWare는 통합시스템으로서 CoSpace, CoDocs, CoMail로 명명된 세 개의 관련된 시스템으로 구성된다. CoSpace는 자료의 저장과 공유를 위하여 개인 및 작업그룹을 위한 작업공간을 제공하고, CoDocs는 전자문서의 체계적인 관리를 지원하며, CoMail은 실시간 의사전달의 기능을 제공한다. CoSpace, CoDocs, 그리고 CoMail은 기본적으로 사용자 정보, 사용자 그룹정보, 작업그룹정보의 공유를 통하여 상호 연계되어, 보다 자연스럽고 효율적으로 공동작업을 지원할 수 있다. With rapid growth of World-Wide Web(WWW or Web), much interest has shifted to develop a Web-based collaborative work system which supports information sharing and reusing. Most of collaborative works in a company or a public corporation are widely distributed. In such an environment, members of work groups require workspaces for exchanging and sharing information. In addition to those workspaces, it is desirable to support real-time messaging facility and systematic management of technical documents produced during collaborative works. In this paper, we describe the design and implementation of a Web-based groupware, named CoWare, which supports effective collaboration. The CoWare system is an integrated system including three related systems : CoSpace, CoDocs and CoMail. The CoSpace system provides personal workspace and shared workspace for storing and sharing informations. The CoDocs system manages electronic documents systematically, while the CoMail system supports real-time messaging facility. Basically, the user information, the user group information, and the work group information are shared among CoSpace, CoDocs, and CoMail. Thereby, the CoWare system supports more natural and effective collaboration.

이명준,박양수,유양우,문남두,김진홍,안건태 울산대학교 2000 공학연구논문집 Vol.31 No.1

현재 대부분의 이동 에이전트 시스템들은 그들 자신의 구조를 가지며 서로 다른 방법으로 구현되어 있다. 이러한 에이전트 시스템들은 서로 다른 인터페이스를 제공하고 있어서 이기종의 에이전트 시스템에서 새성된 에이전트들은 상호 이동하여 작업을 수행할 수 없다. 이러한 문제를 해결하기 위하여 이동 에이전트 시스템간의 상호운용성 지원이 중요한 과제로 다루어지고 있다. OMG(Object Management Group)는 이질적인 에이전트 시스템간의 상호운용성을 증진시킬 목적으로 MAF(Mobile Agent Facilities)명세를 제안하였다. MAF명세는 MADAgentsystem과 MAFFinder 두개의 인터페이스로 구성되어 있으며 에니전트 관리, 코드의 이동성, 명명 규칙에 관한 기능을 제공한다. 본 논문에선는 OMG의 MAF 명세를 만족하는 SMART 이동 에이전트 시스템의 설계와 이의 구현에 대하여 설명한다 SMART 이동 에이전트 시스템의 구성은 에이전트를 실행시키는 환경을 제공하는 플레이스(place), 에이전트의 라이프사이클과 플레이스를 감시하는 모니터(monitor) 그리고 에니전트에게 시스템의 자원을 할당하는 자원관리자(resource manager)로 이루어져 있다. Most current mobile agent systems adopted their own architectures, being implemented in various ways. Since those agent systems provide different interfaces, agents created in one mobile agent system could not move to other agent systems to perform their tasks. To solve this problem, interoperability becomes one of the important issues on mobile agent systems. The OMG(Object Management Group) proposed the MAF(MAF(Mobile Agent Facilities) specification for the interoperability among heterogeneous mobile agent systems. the MAF specification contains MAF Agent System and MAFFinder interfaces, and defines agent management, code mobility and naming rules. In this paper, we describe the design and implementaion of the SMART mobile agent system which satisfies the OMG MAF specification. The SMART system consists of Places that provide execution environments for agents, Monitor that monitors life-cycle of agents and places, and Resource Manager that allocates resources of system for agent.

This experiment was conducted to determine the effects of applying level of pig slurry on the characteristics of runoff and leaching water in lysimeter. Treatments were broken down into five treatments such as non-chemical fertilizer, chemical fertilizer (200㎏ N/㏊) and pig slurry (200, 400, 600㎏ N/㏊), and 3-time-repeated randomized complete block design was fulfilled. The concentrations of NO₃-N was raised(p<0.05) in proportion to the applying level of pig slurry. NO₃-N concentration of leaching water collected from soil depth 20㎝ and 40㎝ was intensified as the applying level of pig slurry was higher (p<0.05) in pig slurry 600㎏ N/㏊ application. In conclusion, pig slurry at the volcanic ash soil in Jeju area can replace the chemical fertilizer as it is tested that applying 200㎏ N/㏊ of pig slurry and chemical fertilizer show the same productivity of sorghum×sudangrass hybrid. But more than 200㎏ N/㏊ of pig slurry may not be appropriate because it may contaminate the runoff and leaching water even though it may increase for the forage productivity.

본 시험은 버뮤다초지에서 이탈리안 라이그라스 파종시기가 목초생산성 및 식생변화에 대해 조사하기 위하여 2009년 9월부터 2010년 10월까지 해발 200 m에 위치한 제주도 제주시 오등동에 위치한 국립축산과학원 난지축산시험장 방목초지 (해발 200 m)에서 수행되었다. 남방형 목초인 버뮤다그라스 초지에서 시험구를 난괴법 3반복으로 배치하였다. 이탈리안 라이그라스는 파종전 버뮤다그라스 목초를 초장이 2~3 cm 정도 높이로 예취를 한 후 파종을 하였다. 이탈리안 라이그라스 파종은 9월 16일, 9월 30일 및 10월 16일에 조파하였다. 이탈리안 라이그라스의 건물수량은 9월 16일 파종구가 가장 수량이 높았으며, 10월 16일 및 9월 30일 파종구는 차이를 보이지 않았다. 보파한 이탈리안 라이그라스는 버뮤다그라스의 건물수량에 영향을 주지 않았으며, 버뮤다그라스는 8월에 가장 높은 생산성을 보였다. 식생변화에서 이탈리안 라이그라스는 발아 후 초기 생육기에 경합이 이루어져 초기생육이 부진하게 나타났으나, 이듬해 봄에 기온이 상승하면서 6월까지 이탈리안 라이그라스 위주의 식생을 보이다가 고온기에 들어서면서 버뮤다그라스 위주의 식생구성을 보였다. 이상의 결과를 종합해 볼 때 버뮤다그라스 목초지에 동계 사료작물인 이탈리안 라이그라스의 파종은 양질의 조사료를 생산하고 목초지의 이용효율을 높일 수 있을 것으로 사료된다. This study was carried out to determine the effect of seeding dates of Italian ryegrass interseeded into bermudagrass sod on the forage productivity and botanical composition of Italian ryegrass and bermudagrass. Experimental plot was located at 200 m altitude within Subtropical Animal Experiment Station, National Institute of Animal Science in Jeju from 2009 to 2010. Seeding date treatments of Italian ryegrass into bermudagrass sod were arranged in a randomized complete block design replicated three times. Italian ryegrass was drilled in row 20 cm apart after clipping the bermudagrass at a cutting height of 2~3 cm. Seeding time was on 16 September, 30 September and 16 October. The dry matter yield of Italian ryegrass was higher in 16 September seeding treatment, the dry matter yields of 30 September and 16 October seeding treatment were not different. The Italian ryegrass interseeded into bermudagrass sod didn't affect the dry matter yield in the summer harvests of bermudagrass, and the dry matter yield of bermudagrass showed the highest in August. In botanical composition, Italian ryegrass showed to reduced growth in early seedling stage after seeding by competition with bermudagrass, but Italian ryegrass was dominant to June increasing of temperature in spring next year and bermudagrass after Italian ryegrass harvests was dominant during summer season.

Kim, Nam Young,Son, Jun Kyu,Cho, In Cheol,Shin, Sang Min,Park, Seol Hwa,Seong, Pil Nam,Woo, Jae Hoon,Park, Nam Geon,Park, Hee Bok Asian Australasian Association of Animal Productio 2018 Animal Bioscience Vol.31 No.8

Objective: Temperament can be defined as a type of behavioral tendency that appears in a relatively stable manner in responses to various external stimuli over time. The aim of this study was to estimate genetic parameters for the records of temperament testing that are used to improve the temperament of Jeju crossbred (Jeju${\times}$Thoroughbred) horses. Methods: This study was conducted using 205 horses (101 females and 104 males) produced between 2010 and 2015. The experimental animals were imprinted and tamed according to the Manual for Horse Taming and Evaluation for Therapeutic Riding Horses and evaluated according to the categories for temperament testing (gentleness, patience, aggressiveness, sensitivity, and friendliness) between 15 months and 18 months of age. Each category was scored on a five-point linear scale. Genetic parameters for the test categories were analyzed using a multi-trait mixed model with repeated records. The ASReml program was used to analyze the data. Results: The heritability of gentleness, patience, aggressiveness, sensitivity and friendliness ranged from 0.08 to 0.53. The standard errors of estimated heritability ranged from 0.13 to 0.17. The test categories showed high genetic correlations with each other, ranging from 0.96 to 0.99 and high repeatability, ranging from 0.70 to 0.73. Conclusion: The results of this study showed that the test categories had moderate heritability and high genetic correlations, but additional studies may be necessary to use the results for the improvement programs of the temperament of Jeju crossbred horses.

This study was conducted to determine the effects of application levels of pig slurry on the c㏊racteristics of runoff water in volcanic ash soil in Jeju, Korea. This study was arranged in randomized complete block design. The data represent the means of the three experiments. Experimental plots were consisted of five treatments such as no fertilizer, chemical fertilizer at 200㎏ N/㏊/year and pig slurry levels at 200, 400 and 600㎏ N/㏊/year. The concentrations of BOD and COD in 600㎏ N/㏊ pig slurry were significantly higher (p<0.05) t㏊n those of the other treatments at initial sampling at 12 days after application. The total nitrogen concentration in runoff water increased with increasing pig slurry. The total phosphorous concentration in runoff water was ㏊rdly influenced by application levels of pig slurry since there were no significant difference among the treatments. The concentrations of NO₃-N and NH₄-N were raised (p<0.05) in proportion to application levels of pig slurry. In conclusion, pig slurry usage at 200㎏ N/㏊ to the volcanic ash soil in Jeju area can replace the chemical fertilizer. However, more t㏊n 200㎏ N/㏊ of pig slurry may not be appropriate, because it may contaminate the water environment. 제주지역에서 사료작물 작부체계에 있어 여름철에 주로 재배되고 있는 수수×수수 교잡종을 공시하여 lysimeter에 돈분액비 시용수준이유거수의 특성에 미치는 영향을 구명하기 위하여 무비구, 화학비료구(200㎏ N/㏊), 돈분액비 시용구(200, 400, 600㎏ N/㏊) 등 5처리를 두어 난괴법 3반복으로 수행하였다. 돈분액비의 시용 초기에 유거수내 BOD 및 COD는 돈분액비 600㎏ N/㏊ 시용구가 다른 처리구에 비해 유의적으로 높았다(p<0.05). 또한 돈분액비 시용량이 증가할수록 유거수의 T-N는 증가하였다. 그러나 유거수 중의 T-P 농도는 돈분액비 시용수준에 대한 영향은 크게 나타나지 않았다. 유거수 중의 NO₃-N 및 NH₄-N 농도는 돈분액비 시용수준이 증가할 수록 높았다(p<0.05). 결론적으로 제주 화산회토양에서는 돈분액비 시용량이 증가할 수록 수수×수수 교잡종의 건물수량은 높일 수 있으나 유거수에 의한 환경오염이 우려된다. 따라서 제주 화산회토양에서 화학비료를 대체하기 위한 돈분액비 이용은 200㎏ N/㏊ 시용하는 것이 환경 오염방지 측면에서 안전할 것으로 판단된다.

Alterations affecting the status of robustness and health can bring about physiological changes including hematological parameters in pigs. To identify quantitative trait loci (QTL) associated with 8 hematological phenotypes (one leukocyte trait, six erythrocyte traits, and one platelet trait), we performed a genome-wide association study using the Porcine SNP 60K BeadChip in an intercross population between Landrace and Korean native pigs. A total of 36,740 SNPs from 816 F2 offspring were analysed for each blood related traits after filtering by quality control. Data were analysed genome-wide rapid association using the mixed model and regression (GRAMMAR) approach. A total of 257 significant SNPs (P<1.36x10-6) on SSC3, 6, 8, 13, and 17 were detected for blood related traits in this study. Interestingly, the genomic region between 17.9 and 130 Mb on SSC8 was found to be significantly associated with RBC, MCV, and MCH. Our results include 5 significant SNPs within five candidate genes (KIT, IL15, TXK, ARAP2, and ERG) for hematopoiesis. Further validation of these identified SNPs could give valuable information for understanding the variation of hematological traits in swine.

High-resolution quantitative trait locus analysis reveals association of BRMS1L with total teat number in a large intercross between Landrace and Korean native pigs

Previously, we reported a quantitative trait locus (QTL) that affect total teat number (TTN) on pig chromosome 7 (SSC7) in a large F2 intercross population between Landrace and Korean native pigs. The aim of this study was to refine the QTL associated with TTN and to identify positional candidate gene(s) within the refined genomic region. TTN was recorded in 1,105 F2 progeny. All experimental animals were genotyped using 998 informative single nucleotide polymorphism (SNP) markers located on SSC7. A haplotype-based linkage and association analysis using the PHASEBOOK programme was applied to perform high-resolution QTL analysis. Additionally, linear mixed-effect models were used to assess the effect of a positional candidate gene on TTN and other economically important traits [i.e., thoracic vertebrae number (THO), carcass body length (CBL) and weight (CW), back fat thickness (BFT) and intramuscular fat content (IMF) in loin muscles]. Joint linkage and association analysis refined the critical region to a 1.07 Mb region that included a novel positional candidate gene, BRMS1L, that encodes the breast cancer metastasis-suppressor 1-like protein, which could possibly be implicated in normal mammary gland development. Significant association of an SNP marker (g.-1087 G>A) in the 5’-flanking region of BRMS1L with TTN (P=1.10x10-8), THO (P=5.80x10-4), and CBL (P=0.038) was observed. Based on these data, we propose BRMS1L as a positional candidate gene for TTN in pigs. After validation of the association in other independent populations and further functional studies, these results could be useful in optimizing breeding programmes that improve TTN and other economically important traits in swine
