Vascular plants of this area consisted of total 379 taxa; 6 forms, 45 varieties, 328 species, 253 genera, 97 families. It corresponds to 9.31% of totally 4,071 taxa distributed in Korea. The useful plants of this area were 315 taxa. It corresponds to 83.1% of collected plants in this area. Among the useful plants, there were 161 taxa of edible source, 121 taxa of pastural source, 147 taxa of medicinal source, 82 taxa of ornamental source, 11 taxa of timber source, 14 taxa of industrial source. Korean endemic plants were composed of 16 taxa - 14 families, 16 genera, 12 species, 3 varieties, 1 forma. It corresponded to 4.2% of collected materials. The floristic specialized species of $III{\sim}V$ grades were 9 taxa, it correspond to 2.3% of collected materials. The naturalized plants were 15 taxa, it corresponded to 6.7% of 225 taxa distributed in Korea.

  • This study was conducted to get information of Fusarium wilt resistance for introduced lettuce cultivars from 12 countries. 111 developed cultivars introduced from 12 countries showed intense and broad resistance symptom. The withered rates of the 111 accessions widely ranged from 0(no symptom) to 4(completely died caused by Fusarium wilt) index. The average of pathogenicity of all evaluated accessions was $2.6{\pm}0.19$. Among them, 7 accessions including IT 294125 showed strong resistance(100 percent survival from Fusarium wilt) and 16 accessions including IT 289569, showed high level of resistance that is higher than 80% of 0 level and lower than 20 % of 3 or 4 level to young plants evaluated. Among the 16 accessions, 11 accessions were developed from U.S.A, 4 accessions from Turkey, and 1 from China. The 16 accessions consisted of 8 crisphead, 5 leaf lettuce, 2 romain type, and 1 stem type. As a result, 16 accessions which showed high level of resistance to Fusarium wilt can be possible to be used by commercial farmers and breeders. However, research related to the exploration of appropriate materials(accessions) for breeding cultivars with variable characters, good quality, high functional components, high consumer acceptability, etc. should be continued, considering pathogenicity test was conducted in young stage.

  • 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.

  • A cloud computing is one of a parallel and distributed computing. The cloud computing provides some service for user with virtual resources. However, a user's service request does not show a time pattern. As a result, each resource also shows a different availability at the same time. This difference affects a quality of service (QoS) and a resource selection for users. Therefore, we propose the resource availability-based multi auction model for cloud service reservation and resource brokering system. The proposed system is to select the proper resource provider based on the users' request. The proposal adopts the multi phase of the auction to transact resources. The system evaluates the available factor of each resource on the auction phase, and finally reserves the service on the adaptive queue. The proposed model shows the better performance than other existing method.

  • Since the solar radiation is the main input for sizing any solar system, it will be necessary to understand and evaluate the insolation data. The Korea Institute of Energy and Resources (KIER) has began collecting horizontal insolation data since May, 1982 at 15 different locations. Because of a poor reliability of existing data, KIER's new data will be extensively used by the solar system users as well as by research institutes. Among some significant results, we obtained the good results more than we had expected, it is very encouraging that the mean value of Korea's solar radiation is increased by more than 30%.

  • 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.
