  • "Hongso" was originated from a cross between "Yoko" and "Hongro" in NIHHS, RDA, in 1989. "Hongso" was preliminarily selected in 2002 for its high fruit quality. After regional adaptability test at five sites from 2003 to 2006 as "Wonkyo Ga-30" it was finally selected in 2006. Optimum harvest time is early September which is similar to that of "Hongro". Fruit shape is globose conical and skin color is light red. Mean fruit weight is 295g and soluble solids content is 14.1oBrix. Fruits acidity is 0.34%, which is higher than that of "Hongro"(0.23%). It has a good taste for harmony of sugar and acidity. Storability is 3 weeks in room temperature. It is apt to russet on fruit skin. It is susceptible to Bitter rot. "Hongso" has a good cross compatibility with major cultivars such as "Fuji", "Hongro" and "Tsugaru". Tree habit is semi-spreading and tree vigor is weak. "Hongso" is high-density cultivation type cultivar, because it has a precocity, spur-type.

  • This study aims to deduce operational implication of R-WeSET program through women students in science & engineering and companies's perception and assessment on the basis of NCS key competency. The significant results are as follows. Firstly, companies and women students in science & engineering share a similar perception on importance of NCS key competencies. The programs should be reviewed and improved for women students who are truly aware of companies' needs. Secondly, the main areas of NCS key competency that are poor in companies' perception are 'positive thinking & drive', 'creativity & challenge spirit', 'communication skills' and 'problem-solving skills'. To enhance these weak skills, activating the actual programs such as "Convergence Design Camp", "Field Adaptability Improvement" and developing the new communication program are required. Lastly, most of women students have attained the satisfying result from "Field Competency Reinforcement Program". Especially, "Industry Field Training" shared the great progresses on all skills of key competency, hence why the progressive model should be developed in the future. This study figures out who's the right person for the 4th Industrial Revolution era, producing a meaningful result in order to change in the higher education system of women students and to grow human resources who will contribute to the community and company.

  • Recent drought events in the South Korea and the magnitude of drought losses indicate the continuing vulnerability of the agricultural drought. Various studies have been performed on drought hazard assessment at the regional scales, but until recently, drought management has been response oriented with little attention to mitigation and preparedness. A vulnerability assessment is introduced in order to preemptively respond to agricultural drought and to predict the occurrence of drought. This paper presents a method for spatial, Geographic Information Systems-based assessment of agricultural drought vulnerability in South Korea. It was hypothesized that the key 14 items that define agricultural drought vulnerability were meteorological, agricultural reservoir, social, and adaptability factors. Also, this study is to analyze agricultural drought vulnerability by comparing vulnerability assessment according to weighting method. The weight of the evaluation elements is expressed through the Analytic Hierarchy Process (AHP), which includes subjective elements such as surveys, and the Entropy method using attribute information of the evaluation items. The agricultural drought vulnerability map was created through development of a numerical weighting scheme to evaluate the drought potential of the classes within each factor. This vulnerability assessment is calculated the vulnerability index based on the weight, and analyze the vulnerable map from 2015 to 2019. The identification of agricultural drought vulnerability is an essential step in addressing the issue of drought vulnerability in the South Korea and can lead to mitigation-oriented drought management and supports government policymaking.

  • This study evaluated newly introduced, commercial super sweet corn hybrids (Zea mays L.) for their potential as breeding materials. Agronomic traits were measured and variance components were obtained using a linear mixed model to estimate the heritability. The trials were carried out in 2018 at two locations (Haenam and Oksan in South Korea). All traits had low heritability, except for mid tasseling and silking days. These traits with low heritability mostly had low genetic variance component estimate. In case of ear height ratio, significant genotype by location appeared to be responsible for low genetic variance, which in turn led to low heritability. Low heritability estimates from the trials with commercial hybrids were perhaps because those hybrids were highly improved for commercial success. Hence, this does not necessarily point to them having poor potential as breeding materials. To overcome low heritability, significant genotype by environment interaction, and achieve high selection efficiency, intermating among hybrids is recommended to create new recombinants before inbred line development.

  • The region of Southeast Asia had already experienced rapid urbanization and cultural change before the East Asia region did. None the less, nowadays shophouses and rowhouses still form the major portion of streets in Chinese town in Southeast Asia countries. The purpose of this study is to examine the adaptation process of shophouse and rowhouse in the Southeast Asia region and the architectural characteristics between the middle of 18th and the early of 20th, which Chinese people of the region inherit and develop, for more thorough understanding of cultural adaptability and regionalism of Chinese architecture in Southeast Asia. The common fact found in the Southeast Asia region is that Chinese people in countries of this region gradually started to live densely as a group in a certain zone in city area since they got to play important roles in commerce, trade and service works related with cities, due to European countries' advance into Southeast Asia and their construction of colonial cities in the region. Chinese people in the region utilized residential rowhouse and special shophouse, which is a kind of shop adapted from rowhouses' sitting room or storage, for their commercial and industrial activities in urban areas, which had problems of limited space. They also realized high densities through vertical expansion of space in order to adjust to changing urban structure under execution of urban planning in cities of colonial area and rapid urbanization. Even though residence of Chinese in Southeast Asia was influenced by new political, social, economic and cultural rules of European colonies in Southeast Asia, it has continuously succeeded to the cultural tradition of China, their home country, in terms of planning principle which puts air well in the middle and hierarchial spacial construction method. Appearance of the open connected verandah, designed by Stamford Raffles, the founder of Singapore, can be regarded as one of the architectural characters. Hence, Chinese residence in cities of Southeast Asia can be understood as a new regional architectural culture in the context of European countries' urban planning and urbanization of colonial areas, Immigrants from southern China and their role, their adjustment to urban areas by utilizing mixed type houses of residence and business, cultural tradition of Chinese home country.
