Purpose - In endless competition, companies pursue cost reduction and work efficiency. So, entrepreneurs try to increase job intensity, which may lead to job stress and high turnovers because of job burnout. But, Information systems are acknowledged as a work support tool that secures work convenience and the productivity of employees. In this study, we aimed to confirm the effects of information systems in reduing the work overload of employees in a human resource intensive industry. Research design, data and methodology - This is based on the job demands-resources model, conducting an empirical analysis of surveys given to hospital employees working in a human resource intensive industry. Results - The research revealed that information systems reduced the work overload of employees in a human resource intensive industry. Conclusion - This study confirmed the effects of information systems as a job resource based on JD-R theory, and presentation of empirical results indicated that information systems alleviate employee job overload and increases job satisfaction in the medical services industry. In the medical services industry, using electronic health record system decreases in work overload, which results in employees gaining time for self-development and time management, reducing job stress, and leading to job satisfaction.

The purpose of development new variety ‘Miho’ (Hordeum vulgare L.) is a favorite with livestock feed and develop varieties resistant to disease and lodging. ‘Miho’ was carrying the growth habit of group Ⅲ, green and mid-wide leaf. Awn that are related to preference of livestock is a semi-smooth awn. This cultivar had 96cm of culm length, 650 of spikes per m2. Heading date of ‘Miho’ is April 27, and maturing dates on May 30, which were later than cultivar ‘Youngyang’. It also showed strong winter hardiness, and similar resistance to shattering and BaYMV compared with those of check one. The best thing among the traits of one is a new good quality with the plant green at the latter growing period. The average forage dry matter yield in the regional yield trial was about 13.1, 12.1 MT per ha in upland and paddy field, respectively, which were 9%, 2% higher than that of the check cultivar. It’s also showed 6.8% crude protein, 27.1% ADF (acid detergent fiber), and 67.5% TDN (Total Digestible Nutrients), including higher silage quality for whole crop barley. This cultivar would be suitable for the area whose daily minimum temperature was above -8℃ in January in Korean peninsula.

Doubled haploid system is a very effective tool which has been widely applied in wheat breeding programmes. Wide-hybridization, wheat X maize cross, is used for the production of wheat doubled haploids (DH). The introduction of doubled haploid (DH) approach into breeding programs has reduced the times and population sizes required for the production of pure lines. We carried out the experiment for development on effective method of producing haploid in wheat. Emasculated spikelets of wheat were pollinated with maize pollen and cultured in the solution containing 40 g/ℓ sucrose and 2,4-D, ABA and GA3 24 h after pollination, and then incubated until embryo rescue. twelve to fourteen days after pollination, the embryos are excised and cultured in half-strength MS basal medium supplemented with 20 g/ℓ sucrose and 1 ㎎/ℓ NAA. The type of plant growth regulators was found to be most significant in production of haploid plants. The application of synthetic auxins to pollinated florets, stimulates haploid embryo development to a stage where the embryos can be rescued onto nutrient media. The percentage of embryos formed was significantly affected by 100 ㎎/ℓ 2,4-D plus 50 ㎎/ℓ BAP and 100 ㎎/ℓ 2,4-D plus 50 ㎎/ℓ GA3. There was varied efficiency in embryo formation from 5.7 to 53%.

‘Jungmo2502’ awnless barley line (Hordeum vulgare L.) developed at National Institute of Crop Science, RDA in 2011. The Jungmo2502 derived from three-way cross between Millyang100 and F1 (Samheung/Suwon300) in 2000. Subsequent generation were handled by the bulk method in a pedigree selection program. A promising line showed high yield as well as lodging resistance in the yield trial tested at Iksan in 2007 to 2008, designated as Iksan 448. The line in the regional yield trials(RYT) tested in seven locations around Korea for three years from 2009 to 2011. The Jungmo2502 is carrying the growth habit of Ⅳ, green leaf and stem similar to the check cultivar ′Youngyang′. Its heading date was May 3, and maturing time was May 30 in paddy field, which was 3 days later respectively than check cultivar. It was 98 cm of culm length, 607 spikes per m2 and showed more rate of leaf blade, winter hardiness, and resistance to BaYMV than the check cultivar. Average dry matter yield was similar with the check cultivar in paddy field (about 11 ton ha-1). It also showed good qualities as 8.7% of crude protein, 21.9% of ADF (acid detergent fiber), 40.7% of NDF (neutral detergent fiber), and 71.6% of TDN (total digestible nutrients), including high grade of silage for whole crop barley.

In order to get information on tocopherol content and composition in fifty-six soybean germplasms were evaluated by HPLC. From the principle component analysis, the first three components accounted for 71.6% of the total variance of tocopherol content in the germplasms. Principal component 1 showed significant correlations with all the morphological markers except 100-seed weight. Soybean germplasms were divided into three groups by the first two principal components. The highest content of α -tocopherol was 38.6~mug per g in Tanner, while that of ~gamma -tocopherol was 195.6~mug in PI 91073. In case of δ -tocopherol, IT 105622 showed the highest value as 29.8~mug . The contents of tocopherol were gradually increased from the late August to late September, which was 10 days before maturity, in Alchankong and PI 96322. The tocopherol content was higher in seeds from the plants sown early than those sown late. Total tocopherol contents of PI 96188, Geomjeongkong 2, and Suwon 183 grown in Gimje were higher than those grown in Iksan, but the difference was not observed in PI 96322. These results suggest that the contents of tocopherol in soybean were affected not only by the genotypes but also by environment.
