  • The purpose of this study is to analyze service quality factors that affect user satisfaction of NDSL Open Service (NOS) and to improve standards of open service for sharing information through the user satisfaction survey. User satisfaction indexes were developed to measure the all aspects of the NOS services. The quality index, satisfaction index, and performance index were identified in this survey. According to the survey findings, the levels of social quality and social satisfaction are relatively high, this shows the positive evaluation and expectation of researchers for open services. However, relatively low level is identified in area of service process quality. Therefore, NOS requires method to help easily take advantage of OpenAPI and strategy to increase service process satisfaction and service environment satisfaction.

  • Trifluralin (2, 6-dinitro-N, N-dipropyl-4- (trifluormethyl) benzenamine) was applied preemergent to soybean in plots drained or nondrained, in louisiana. Plots 14.6 ha were arranged to give 1683 g/ha of trifluralin. The half life of trifluralin in the top 15 cm of soil was 42.6 darts and f6.0 days in nondrained plot and drained plot, respectively. The concentrations of trifluralin in surface runoff water and subsurface runoff water were 0.62 ng/ml-0.02 ng/ml and 11.06 ng/ml-0.02 ng/ml, respectively. The concentration of trifluralin in runoff water was smaller than 2 ng/ml for trifluralin of U.S. Environmental Protection Agency advisory. Total loss of trifluralin in runoff water was 0.021 % of applied amount at drained plots during three month after application. Trifluralin was moved hardly in the water. Subsurface drainage -reduced trifluralin losses because concentration of trifluralin in the subsurface runoff water in drained fields was low.

  • This study was conducted to find the control methods, status of overwintering and seasonal occurrence of Erioccoccus largerstroemiae on persimmon trees in Ch'ondo area, Kyongbuk province in Korea. Usually, overwintering eggs were sheltered in bark, among them the rate of alive eggs was 28.7%. The activiation of garpe-myrtle scale showed from late April, and they have three generations per year. The first occurrence of larval stage of Erioccoccus largerstroemiae starts from late June to early July, the second occurrence begins from middle August to late August, and from late June to early July, the second occurrence begins from middle August to late August, and from middle September to late September is the third, thus, three peaks of occurrence revealed in early July middle August, and late September respectively. Average number of eggs conceived in female adult was 229.3. Spray effect of chemical control showed as follows; lime sulfur with tow applications of pesticides (late June, late August) at 97.8%, machine oil with tow applications of pesticides (late June, late August) at 96.8%. And during the growing period, the spray results using three applications of pesticide only (late June, late August, amid September) showed 77.2% in field condition.

  • Although it is expected to provide fundamental data for advanced VTS system by analyzing traffic accidents in VTS area, there is no quantitative analysis to find it.. In this research, it is examined and analyzed marine casualties records(1999-2004), data of Port-MIS and data of each VTS center. The results of this research are as below. 1) It is necessary to reduce traffic accident and to improve VTS operating system. 2) It is discovered for statistical discrepancy between vessels controlled by VTS and vessels not controlled by VTS in accident cause, visibility, perception distance and cause of late perception in collision accidents 3) It is necessary for VTS assistance to be positive and to made in ample time consecutively. 4) As the result of traffic accident prediction model, it is necessary to develop a system improving VTS operators' ability to identify dangerous ships.

  • The purpose of this study is to investigate the quality characteristic of cholesterol free milk helping the reduction of serum cholesterol. Cholesterol free milk stored at $10\pm1^{\circ}C$ was evaluated with general analysis, stability, cholesterol, microorganism, aflatoxin $M_1$, antibiotic, antibacterial agent, color, and sensory evaluation. Animal fat contents were significant (p<0.05), but normal values. Quality characteristics of alcohol test, freezing point, and somatic cell count were general milk data with stability. Cholesterol content, microorganism, and aflatoxin MI were not detected. Also antibiotic and antibacterial agent residues were not detected by Parallux, Charm II, TTC II, and Eclipse method. Color of CFM1 was significant, while CFM2 was similar with conventional milk. Compared to control milk made by conventional way, QDA scores of color and mouthfeel in CFM1 were significantly different, whereas CFM2 did not show any significant. These Quality characteristic results suggested that health-oriented cholesterol free milk would be made by food additive.

  • To investigate the effects of topping method on the yield and major agronomic traits of three varieties differed in plant type of Hibiscus manihot the experiments were carried out Mokpo Branch Station of Crop Experiment Station, in 1993. Fresh weight of root, dry weight of culm, dry weight of capsule and dry matter ratio on root were highest in the long culmed variety, and at the plots with topping of growing point in main culm and branches(Treatment No.3). Considering from the above results, optimum topping method seemed to be topping of growing point in main culm and branches in the long culmed variety.

  • Effects of Choline Chloride on growth and yields of sweet-potato cultivated with the single crop and after-barley crop were summarized as follows. 1. The greatest effect was obtained when the sprout-bases of sweet potato were soaked in the solution of Choline Chloride for 24 hours, while the optimum concentration of Choline Chloride was 32.3ppm in case of single crop and 31.1ppm in after barley crop respectively. 2. Choline Chloride restrained the growth of stem; the length shortened and the dry weight decreased. 3. The number of tubers and yields were increased by treating choline chloride. It may be thought that the translocations of assimilation substance from leaves and stem to tubers, was stimulated by treating choline chloride. The tendancy of higher yielding was shown in the early harvesting than in the usual harvesting 4. Sugar and starch content were higher, crude fiber and crude protein content were lower as compared with the control.

  • An advanced method of Relaxed Static Stability (RSS) is utilized for improving the aerodynamic performance of modern version supersonic jet fighter aircraft. The flight control system utilize RSS criteria in both longitudinal and lateral-directional axes to achieve performance enhancements and improve stability. The T-50 advanced trainer employs the RSS concept in order to improve the aerodynamic performance and the flight control law in order to guarantee aircraft stability. The longitudinal two modes are the short period with high frequency and the phugoid mode with low frequency. The design goals of longitudinal control laws is concerned with the short period damping and frequency optimization using lower order equivalent system and utilizing the requirement of MIL-F-8785C. Analysis of short period mode has been and continues to be performed This paper addresses the analysis of aircraft phugoid node characteristics such as damping, natural frequency, and analysis of aircraft pitch motion that impacted by angle of attack limiter and auto pitch attitude control law.

  • With a purpose to obtain basic informaton for improving poorly drained soil, a pot experiment was conducted about the effect of percolation rate on growth and yield of rice under application of wollastonite and rice straw as soil conditioner. The sandy and clayey soils were selected to compare difference in effectiveness of poor drainage. The results were summarized as follows: 1. Increasing or percolation rate increased rice yield in both sandy and clayey soils, but the effectiveness on yield increase was greater in clayey soil than in sandy. 2. Various materials of soil solution produced from the process of soil reduction were high at the early growing stage, but they were gradually decreased at the later growing stage. 3. With increasing percolation rate, the contents of N, $P_2O_5$ and $K_2O$ in rice plant were decreased, but that of $SiO_2$ was increased. 4. The number of roots at harvest was greater with increased extension as infiltration rate was increased.
