  • The research was conducted to evaluate a different seedling establishment of rice germplasms which were obtained from the IRRI (International Rice Research Institute) under the direct seeded condition. There was highly significant difference in terms of statistical analysis among cultivars. The seedling establishment of cultivars tested was the highest with ASD1 > IR50 > IR72 > Taothabi > Uplri5 > CO25 > Dula > Moroberakan. The difference of seedling establishment among cultivars particular in dry condition was high between ASD1 and Moroberakan and other cultivars.

  • The aim of this study is to compare radiation dose in diagnostic X-ray radiography and calculated by different mathematical equation. The result of ESDs direct measurement and that calculated by Mori NDD-M shows the biggest difference. On the other hand, equation by Edmonds shows the lowest difference of ESDs. Also, Rectification due to the difference between direct dose measurement and calculation method commutated three-phase, single phase and inverter type, show less difference in the drive way. In conclusion, this study can be helpful for expecting radiation dose-exposure and control exposure parameters for the diagnostic x-ray radiography.

  • Direct numerical simulation has been used to study turbulent boundary layers with convex curvature. A direct numerical simulation program has been developed to solve incompressible Navier-Stokes equations in generalized coordinates with the finite volume method. We considered two boundary layer thicknesses. When the curvature effect is small, mean velocity statistics show little difference with those of a plane channel flow. Turbulent intensity decreases as curvature increases. Contours suggest that streamwise vorticities are strong where large pressure fluctuations exist.

  • In this paper, a new method to reduce the size of ROM in the direct digital frequency synthesizer (DDFS) is proposed. This method use the sine-linear phase difference method and differential PCM. The new ROM compression method can reduce the ROM size by using the two ROM. The quantized value of sine-linear phase difference is saved by the ROM1 of the $2^N$ sample period. The ROM2 save the difference between the original sine-linear phase difference value and the saved sample value of the ROM1. The ROM compression ratio of 37% is achieved by this method. Also, the power consumption is decreased according to the ROM size reduction.

  • Purpose: This study was done to assess development and postnatal care interventions in postnatal care intervention records for maternity ward nurses in tertiary hospitals and women's hospitals in South Korea. Methods: This mixed-method research was a Time-Motion (TM) study. Data were collected through external observation of 12 nurses in 4 wards over 24 hours. Mann-Whitney U test and independent t-test were employed for the analysis of frequency and provision time of direct/indirect care activity. $x^2$ (Fisher's exact test) was utilized to determine the difference in frequency between two groups. IBM SPSS 22.0 statistical program was employed for calculation. All statistical significance levels were at ${\alpha}=.05$. Results: According to the KPCS-1 (Korean Patient Classification System-1), women's hospitals are group 3 and tertiary hospitals, group 4. With respect to time difference in direct care, tertiary hospitals showed 791 minutes and women's hospitals, 399 a difference of 392 minutes. For time difference in indirect care, women's hospitals had 2,415 minutes while tertiary hospitals, 2,080, a difference of 335 minutes for women's hospitals. No difference was found in the average total care workload between the two institutions. Individual time also showed no difference (p>.05). Conclusion: High-risk maternal care strength in tertiary hospitals and breast-feeding strength in women's hospitals need to be benchmarked with each other.

  • We have constructed a level-1 processor to generate brightness temperatures using the direct-broadcast data from the passive microwave radiometer onboard Aqua satellite. Although 50-minute half-orbit data, called a granule, are being routinely produced by global data centers, to our knowledge, this is the first attempt to process 10-minute long direct-broadcast (DB) data. We found that the processor designed for a granule needs modification to apply to the DB data. The modification includes the correction to path number, the selection of land mask and the manipulation of dummy scans. Pixel-to-pixel comparison with a reference indicates the difference in brightness temperature of about 0.2 K rms and less than 0.05 K mean. The difference comes from the different length of data between 50-minute granule and about 10-minute DB data. In detail, due to the short data length, DB data do not always have correct cold sky mirror count. The DB processing system is automated to enable the near-real time generation of brightness temperatures within 5 minutes after downlink. Through this work, we would be able to enhance the use of AMSR-E data, thus serving the objective of direct-broadcast.

  • Purpose: In this paper, an experimental study was conducted to analyze the difference in shear strength caused by the problem of excluding coarse particles due to the size of the test specimen in the direct shear test. Method: A large-scale direct shear test was conducted on three weathered soils containing coarse aggregates with a maximum diameter of 50mm. In addition, a small-scale direct shear test was performed using a sample with a maximum diameter of 5 mm, excluding coarse aggregates. Result: In the case of the small-scale direct shear test, compared to the results of the large-scale direct shear test containing large particles, the internal friction angle was about 2.3% smaller, and there was no significant difference. In terms of cohesion, compared to the large-scale direct shear test, the small-scale direct shear test derived about 80.3% smaller value, showing a relatively large difference. Conclusion: In the large-scale direct shear test, it was analyzed that the coarse particles had a greater impact on the cohesion than the internal friction angle. Therefore, granite weathered clay containing coarse particles is judged to have the same shear strength as the cohesive force that is not affected by vertical stress. In this study, it was analyzed that the small-scale direct shear test, which excludes the coarse particles that are commonly used, provides results on the safety side by excluding the effect of coarse particles.

  • This study analyzes the satisfaction degree for menu quality of the regional cuisine in Gangwon province. The result of verifying hypotheses is as follows. For the satisfaction with the quality in direct services, it showed no similarity by education levels, locations, and income levels; however, there was a significant difference in satisfaction by gender, locations, and occupation. Males evaluated satisfaction with direct services higher than females, and Chun-Cheon and Sok-Cho residents felt more satisfied than Gang-Reung residents. By occupation, students and self-employed ones showed more satisfaction. For the satisfaction with indirect services, there was a significant difference in 1% of the similarity range by gender, locations, and occupation while no difference was shown in the other variables. Compared with the satisfaction with direct services, satisfaction with indirect services was low, which indicated the necessity of improving indirect services. Indirect services showed the same results of satisfaction by gender, locations, occupation as those of direct services. In particular, it showed high satisfaction among students.

  • In order to study the manufacturing possibility of connecting rod by direct quenching method, the difference between connecting rod by direct quenching and that by general heat treatment were investigated by observing microstructure, by measuring mechanical properties, by conducting fatigue testing, and by measuring the amount of tool wear in actual cutting. Connecting rod manufactured by direct quenching had better fatigue life than that by general heat treatment, which was due to homogeneous microstructure, and higher strength. The amount of cutting tool wear of connecting rod by direct quenching was higher than that by general heat treatment, which was due to low machinability and high toughness of tempered martensite microstructure. Therefore it will be added the study of heat treatment and cutting condition for manufacturing by direct quenching.
