Melons, a rich source of vitamins and fibers, are commonly grown in the soil. Hydroponic cultivation could improve yield and quality of melon and selection of substrate volume and the kind of substrates is important for hydroponic cultivation of melons. This study investigated the effect on melon growth according to volume of granular rockwool and substrates of coir and rockwool slab. ‘Geumsegye’ melon (Cucumis melo L. cv. Geumsegye) was cultivated hydroponically according to volume of granular rockwool to 1.0, 1.5, 2.0, 3.0, and 4.0 L, and was also cultivated using coir and rockwool slabs. Logistic model was applied to estimate the growth characteristics of melons such as plant height, leaf length, leaf width, and the characteristics of fruit. The growth characteristics of melons were significantly increased at 4.0 L compared to those grown of 1.0 L volume of on granular rockwool, and the results were the highest in coir and rockwool slabs. Melons grown in rockwool slabs showed the largest fruit fresh weight, fruit length, and fruit width. During hydroponic cultivation, growth characteristics of melon appropriate at the 4.0 L volume of granular rockwool, and the highest at coir and rockwool slabs. This study provides a basis for understanding the effect of root zone environment to the growth characteristics and fruit quality of non-netted melon.

한국 이러닝 산업의 국내 시장은 포화상태이고 수출지역이 중국 및 일본에 국한되었기 때문에 수출지역 확대를 위한 신규시장 개척이 필요하다. 또한 해외 진출시 필요한 유통망 확보, 객관적 해외시장 정보, 접근전략 등이 포함된 종합적인 해외시장진출 정보 역시 지원되어야 할 시점이다. 이를 위해 한국의 이러닝 산업은 시장성이높지만 한국의 진출이 미미한 수준인 중동권 시장 진출을 추진할 필요가 있다. 또한중동지역 진출과 더불어 그 지역의 사회, 문화와 더불어 기업 현황, 교육 현황, 정부정책 등을 체계적으로 분석하여 추진전략을 세워야 한다.본 연구는 사우디아라비아와 UAE의 이러닝 현황을 조사하고 이러닝 정부정책 현황및 관련기관, 정부부처, 주요기업 등을 유목화 하였다. 그리고 조사내용을 분석하여사우디아라비아와 UAE의 이러닝 시장 진출 전략을 도출하였다. 본 연구의 결과는국내 기업의 이러닝 해외시장 개척 및 글로벌 역량 강화를 촉진하는 자료가 될 것으로 예상된다. 특히 중동권 대표국의 이러닝 시장 전망 및 분석을 통한 정책 수립과산업진출 및 사업전개를 위한 사업실시 매뉴얼 구성을 위한 기초자료로 활용될 수있을 것이다.

Purpose – This study aims to analyze time use of employees to see how they make a balance between work and family. We tried to analyze time use and time pressure of married paid workers in order to understand their work and family balance. Methodology – Time use was compared by employment types and time pressure groups. We analyzed the factors influencing time pressure, dividing two employment types. The data were selected from the 2009 Korean Time Use Survey. Results – Those who feel time pressure among full-timers spent more time on work and housework and less time on personal care and leisure than those who do not feel time pressure. Logit analysis on time pressure showed that full-timers feel more time pressure than part-timers do. Gender, age, education, income, day-off type, and the presence of preschool children were significant variables on time pressure. Conclusion – These results imply that time use and time pressure for married paid workers are affected by employment types. Flexibility of labor needs to enhance work and family balance for females who have preschool children.
