  • Naked oat is particularly vulnerable to cold weather among cereal crops, and frequent lodging due to their long culm length. Also it is difficult to cultivate in double cropping system with rice because of late maturity in Korea. In this study, we charaterized 71 naked oat germplasms including two control varieties with agronomic traits, to select superior resources and use them for the improvement of exsiting varieties. The maturity date was May 26th for 'Joyang' and June 1st for 'Daeyang', and there were 5 resources including IT302003, which was earlier than Daeyang. In the case of culm length, the distribution ranged from 62 to 124 cm, and there were 13 resources, including IT209241, that were shorter than 'Joyang' (84 cm) and 'Daeyang' (83 cm). In correlation analysis of agronomic traits, the highest positive correlation (r=0.89) was observed between days to heading and days to maturity. In addition, culm length and spike length (r=0.72) and days to heading (r=0.50) showed a positive correlation. However, Barley yellow dwarf virus(BYDV) and grain yield (r=-0.30), lodging tolerance and liter weight (r=-0.37) showed a negative correlation. Cluster analysis, resources with similar traits such as liter weight, husk ratio, days to heading, and days to maturing were subclassified. Through this analysis, 6 resources, including IT302002 (X345-1-B4-20-1), which had short culm length, early maturity, and cold tolerance compared to 'Joyang' and 'Daeyang', were selected. Among the selected excellent resources, the avenanthramide content of the four resources was IT302002 (325.18 ㎍/g), K000010 (557.3㎍/g), K253299 (447.33 ㎍/g), and K253301 (440.49 ㎍/g), respectively, which was higher than 'Daeyang' (301.97 ㎍/g). These excellent resources will be used as breeding materials for the development of new varieties in the future.

  • ERP 도입 및 운영과정에 전사적 자원 즉 인적자원과 물적자원이 투입되고 활용되었다. 기업경영에 있어서 제 자원의 관리가 중요하고, 특히 인적자원이 성과에 중요한 영향을 미치고 있다. 그 동안 ERP 도입요인과 도입성과에 대한 기존의 연구는 중소기업을 포함한 전체 기업을 대상으로 한 연구가 대부분이었으며, 그러한 연구의 대부분은 먼저 ERP을 도입한 대기업 위주의 연구였다고 볼 수 있다. 중소제조기업의 ERP 도입요인으로서 열악한 전사적 자원의 수준이 ERP 도입성과 즉 생산효율성에 영향을 미친다는 전제하에 이들 간의 인과관계를 위한 연구모형을 제시하였다.

  • This study was conducted to estimate the days to flowering based on the effective accumulated temperature at various altitudes in the Jiri mountain region and to compare growth and yield characteristics according to the sowing date of safflower (Carthamus tinctorius) four genetic resources (local variety, IT323225, IT333473, and IT333482). The safflower four resources were sown on March 29, May 3, May 13, May 24, and June 2. The days from sowing to flowering of the safflower four resources by sowing dates were in the order of the local variety (61.0 days), IT333482 (73.2 days), IT323225 (74.0 days), and IT333473 (74.2 days). The base temperature and effective accumulated temperature for the days to flowering of the safflower four resources calculated based on the daily mean temperature were local variety 6℃, 579℃, IT323225 11℃, 766℃, IT333473 11℃, 768℃, IT333482 10℃, 750℃, respectively. As a result of applying the calculated effective accumulated temperature and daily mean temperature of the past five years (2019 to 2023) by various altitudes and the different sowing dates (every 15 days from April 1 to August 15), the days to flowering of the safflower four resources decreased from April 1 to July 15 during the sowing date and then tended to increase from August 1. In addition, the days to flowering at various altitudes were investigated in the order of plains, mid-mountain, and mountain regions. Among the yield characteristics, plant height, number of branches, number of capitula, number of seeds, and seed weight decreased as the sowing dates were delayed for the safflower four resources.

  • Clubroot, caused by Plasmodiophora brassicae, is one of the most crucial disease in Kimchi cabbage. Screening disease resistant genetic resources is necessary to develop disease resistant cultivars and conduct related research. We have evaluated the development of clubroot to the 120 genetic resources of Kimchi cabbage introduced from World Vegetable Center and five Asian countries using isolate of Plasmodiophora brassicae collected in Haenam fields in Jeollanam-do Province, Rep. of Korea. This isolate was determined race 2 using differential varieties reported by Kim et al., 2016. IT100384 and IT305623 showed strong resistance, lower than disease index (DI) 1.0. IT100385, 100439, and 135407 showed moderate resistance (1.0

  • The purpose of this paper is to examine IT governance mediated the effect of human resource capability on information systems outsourcing success. The survey method was used for this paper, and data from a total of 108 companies that were listed greater than $10 million were used for the analysis. And structural equation model was used to analyze the data. The results of this empirical study is summarized as followings. First, human resource capability do not have a direct effect on information systems outsourcing success but IT governance mediates the effect of human resource capability. Second, preparedness capability and relationship capability have positive effect on the IT governance. The findings have significant implications for IT governance in information systems outsourcing.

  • This study is to seek to apply resource types of RDA to KCR4. It is difficult to choose appropriate term and to embody FRBR model because GMD of KCR4 is the mixture of content-based vocabularies and carrier-based vocabularies. SMD is to need to reflect the current technological terms. Resource type of RDA was already developed to overcome limitation of AACR2's GMD, and would affect the world cataloging environment, therefore it is need to apply resource type of RDA to Korean cataloging rule. For this study, case study and survey were used. In case study, it was to scan all GMD term for one university library to build by programming and to grape librarian and users' potential need. In the survey by cataloging librarian, it was to figure out the current description of resource type in university library and to test RDA resource type. As a result, it was needed to revise the vocabulary to the obvious and user-understandable list. Also it was different in correction rate in RDA testing by resource type. Based on the case study and the survey, RDA resource type was applied to KCR4 resource list by adding term such as computer game in content type, and by inserting terms such as DVD, CD-ROM, Blu-Ray, computer file in carrier type. It also applied RDA description method and display means to KCR4. This study would apply RDA resource type to KCR4 and contribute to revise KCR4 resource type.

  • International volunteering in education is one of activities in volunteering. Volunteers have been recognizing that educational activities play an important role in volunteering. Recently, there is an increase of participants and various supports for educational volunteering in South Korea. However, regardless of the essential meanings in which activities commonly attempt for deriving local sources in terms of human and resources, many participants in volunteering take advantages of their own purposes and providing their supports in terms of a mercy. This study asserts that this situation comes from the lack of theoretical understanding of volunteering. Therefore, this study realizes a need of providing a theoretical background and purports to suggest it for international volunteering in education. It is the critical pedagogy. Critical pedagogy tries to deconstruct false-consciousness of the oppressed through education. And, it emphasizes that people could have autonomy and self-directed sovereignty. Accordingly, critical pedagogy should be a theoretical background of activities for deriving human's autonomous consciousness and their own resources. Thus, it might be a theoretical background for international volunteering in education.
