  • The study was intended to know the responses of the nitrogen application levels (3, 6, 9, 12 and 15kg ai per $1O^a$) to grain yield and quality of two-malting barley, Golden melon and Hyang maek in 1980. There was investigated chlorophyll content, dry weight, heading, grain yield, yield components, contents of protein, fat and carbohydrate and activity of $\beta$-amylase and invertase. Nitrogen increment was effective to increase of number of grains per spike and number of spikes per unit area, increase of protein content and decrease of $\beta$-amylase activity, but it was not recognized the yield increase under the 12% protein content.

  • This study was carried out to investigate the effects of lime(0, 250, 500 and 1,000 kg/lOa) and phosphate (0, 17 and 34 kg/lOa) applications on growth and nitrogen fixation of alfalfa (Medicago sativa L.). The phosphate applications improved(p<0.05) shoot, root and root nodule dry weight of Alfalfa and acetylene reduction activity of alfalfa with increasing levels of phosphate in the soil pH 6.2 at 7 and 12 weeks(ear1y bloom) after sowing, but these were not influnced with lime applications. Total nitrogen content of each part of alfalfa was increased with lime application, but was not significantly different by levels of lime application at 7 weeks after sowing. Application of phosphate did not affect total nitrogen content of each part of alfalfa. Total nitrogen contents of each part of alfalfa were not significantly different between lime and non-lime application at 12 weeks(ear1y bloom) after sowing but were decreased(p<0.05) with phosphate application(p< 0.05). These results suggest that lime(250 kg/lOa) and phosphate(34 kg/lOa) applications are effective for the growth and the nitrogen fixation of alfalfa at the soil pH 6.20.

  • This study examined the actual use and users‘ satisfaction with the university dormitories in Gwangju and Chonnam and analyse the related variables that affect on them. Self-administered questionnaires were provided to 200 university students from Gwangju and the Chonnam area. The collected data was used to conduct comparative and descriptive statistical analysis: T-test Below are the study findings. Female students express more satisfaction with community affinity than male students in the satisfaction about socio-psychological environment. Students residing in the rooms for 2 persons express more satisfaction with the division of private space with common space, study appropriateness etc. than those residing in the rooms for 4 persons. Students residing in the cluster-type rooms express more satisfaction with the division of private space with common spaces study appropriateness and relationship with other students in other rooms etc. In relation to the room environment, female students express less dissatisfaction with the noise than male students. Students residing in the rooms for 2 persons express more satisfaction with the room size, interior temperature pleasantness, brightness etc. than those residing the in rooms for 4 persons. Students residing in the cluster-type rooms express more satisfaction with the bed size, the condition of interior finishing, interior temperature pleasantness, brightness and interior air pleasantness etc. than those residing in unit-rooms. In relation to common using environment, male students express more satisfaction with the library than female students. And students residing in the rooms for 4 persons and those residing in the cluster-type rooms express more satisfaction with lounge than those residing in the rooms for 2 persons and those residing in the unit-rooms. Organizing the university domitory planning according to the students' demands, based on this study, the change to general function of domitory in sleeping, studying, leisure activity and culture acitivity is needed.

  • This study used the keypoint observed simultaneously on two images and on twodimensional intensity image data, which was obtained along with the two point clouds data that were approached for automatic focus among points on terrestrial LiDAR data, and selected matching point through SIFT algorithm. Also, for matching error diploid, RANSAC algorithm was applied to improve the accuracy of focus. As calculating the degree of three-dimensional rotating transformation, which is the transformation-type parameters between two points, and also the moving amounts of vertical/horizontal, the result was compared with the existing result by hand. As testing the building of College of Science at Konkuk University, the difference of the transformation parameters between the one through automatic matching and the one by hand showed 0.011m, 0.008m, and 0.052m in X, Y, Z directions, which concluded to be used as the data for automatic focus.

  • This paper investigates factors determining the level of nontraditional activities at banks around the world. Specifically, the paper examines what kinds of firm-specific and country-specific characteristics determine the level of noninterest income using a comprehensive multi-country database. This paper focuses beyond the traditional U.S. based analyses and provides detailed asset-liability management practices of banks around the world.The findings suggest that banks' size and loan loss provision, explicit deposit insurance, banking restriction, banking freedom ranking of respective countries, the extent of state and foreign ownership, governance, and transparency of the country have positive effects on the level of nontraditional activities. Greater dependence on traditional lending and financing, market based economy, and multiple bank supervisory bodies in the country have negative associations with noninterest income. The economic development of country however affects the extent of the relationship.

  • This study was to examine relationships among health belief of emerging infectious disease and self-efficacy for healthcare and identify the factors that influence on self-efficacy for healthcare in the general hospital nurses. The data were collected from 150 nurses working in the three general hospitals, located in S and Y city using self-administered questionnaires. Data was collected from January 11, 2021 to January 22. Among sub-factors of the health beliefs, perceived benefit (β=.17, p=.040), perceived sensitivity (β=.19, p=.020), and age (β=.21, p=.005), and these variables explained 14.0% of self-efficacy for healthcare(F=4.28, p<.001). Through this study, it is necessary to develop educational program self-efficacy for healthcare is needed for improving perceived benefit and perceived sensitivity among general hospital nurses.

  • This study aimed to explore the influences of safety attitude for patient and moral sensitivity in practice of standard precaution in small and medium hospital nurses. Data were collected from 150 small and medium hospital nurses in January 11, 2021 to January 22, 2021 and were analyzed using Descriptive statistics, Independent t-test, one-way ANOVA, Pearson correlation coefficients, and multiple regression. Practice of standard precaution was significantly correlated with safety attitude for patient (r=.539, p<.001) and moral sensitivity(r=.249, p=.002). Practice of standard precaution was associated safety attitude for patient, and work unit with 33.8% of the variance(F=18.47, p<.001). Based on the findings of this study, each institution needs to make efforts to strengthen the safety attitude for patient of small and medium hospital nurses for practice of standard precaution.

  • The purpose of this study was to investigate at how the quality of citron changed during storage as a result of the browning inhibitor treatment. In the browning inhibitor treatment, Vit.C, Vit.C+NaCl, Vit.C+NaCl+CD substances were used. As a result of investigating the browning degree, Vit.C+NaCl+CD showed the lowest value of 0.76 when stored for 12 weeks. The 𝚫E of the chromaticity value indicated that significant color change occurred when the value was high. As the Vit.C+NaCl+CD mixture showed the lowest value of 46.01 at 25℃, it was found that browning did not occur much compared to other treatments. The change in polyphenol oxidase (PPO) activity of citron increased as browning progressed. Among the browning inhibitor solutions, Vit.C+NaCl+CD solution showed the lowest value 118.8 u/g at 25℃ after 12 weeks. Based on these findings, it seems that CD mixing solution can be used as a citron browning inhibitor.
