The behavior of fatigue was studied by using low carbon steel bar with microhole(artificial small defect) under the condition of rotary bending stress which is made artificially at smooth surface and round notch root. The results obtained can be summerized; The behavior of non-propagating cracks which are produced at both tips of small defect occurred to dissymmetry, and it is found to be double size of small defect. For the range of l>lc, threshold stress intensity is constant. However, for the range of l

The DIABUTSU hotel was built first in Korea and we know that the hotel was built in 1888. However, it has many questions. This study was conducted to uncover the truth. Non-text media in the study is useful to take advantage of the media. However, it is not used in Korea. I prefer that study by Non-text Media. The findings, DIABUTSU hotel was built in 1884. It was Japanese-style two-story wooden building. HORI was hospitality there and many foreigners stayed. Underwood, Appenzeller and Carles were this hotel and they recorded about the hotel in 1885. We know that three story building was the first hotel. But this is wrong in fact. The first hotel is Japanese-style wooden building built in 1884.

Weathered soil is one of the most representative soils in Korea. In this study, a series of cyclic triaxial tests was carried out to predict the post-cyclic deformation behavior of weathered soils in case of non-liquefaction. Excess pore pressure response during cyclic loading and volumetric strain during the dissipation of excess pore pressure were measured varying the confining pressure, relative density and cyclic stress ratio. Based on the test results, it Is found that the modified excess pore pressure ratio, excess pore pressure ratio normalized by cyclic stress ratio, is uniquely correlated with the number of cycles irrespective of confining pressure and cyclic stress ratio. Using the newly proposed MEPPR(modified excess pore pressure ratio) concept, it is possible to easily evaluate the excess pore pressure and the settlement of weathered soils due to cyclic loading by greatly reduced number of tests. It is also verified that the reconsolidation volumetric strain is independent of the way how the excess pore pressure was generated.

Non-linear loads are the sources of power systems harmonics, and the power quality is influenced by harmonics, Recently, the requirements of power quality is important. For the power quality problems. it is very important that the development of power measurement circuit for non-linear load. In this paper, it is discoursed on that high speed sampling circuit and efficient power analysis algorithms. The sampling circuit is implemented using FPGA. Since the power measurement circuit system is composed by FPGA and efficient power algorithms. it is practicable application that accurate power measurement, stable protection relaying, and low cost system configuring.

Feeding behaviors of the sweet potato whitefly, Bemisia tabaci, and changing of their feeding behaviors were recorded and analyzed with an Electrical Penetration Graph (EPG) analysis against cyantraniliprole. The characteristic patterns of feeding behaviors investigated were as follows; NP (non probing), pathway phase waveform, waveform of feeding xylem. In results, B. tabaci did not almost feeding the phloem. And It was not appeared potential drop during recording time. It was predominantly indicated pathway activity waveform and waveform of xylem feeding. After treatment of cyantraniliprole with recommended concentrations to tomato plants, EPG waveforms were recorded during 3 hours. Cyantraniliprole treatment showed longer time to first feeding xylem than untreated (P=0.043). It was showed shorter duration of first feeding xylem than untreated (P=0.017). And it was showed longer NP (non-probing) time than untreated. Consequently, It was supposed that cyantraniliprole was effect of anti-feeding or avoidance to B. tabaci.

Maximizing energy efficiency minimizes the energy consumption of computation, storage and communications required for IT services, resulting in economic and environmental benefits. Recent advancement of flash and next generation non-volatile memory technology and price decrease of those memories have led to the rise of so-called AFA (All-Flash Array) storage devices made of flash or next generation non-volatile memory. Currently, the AFA devices are rapidly replacing traditional storages in the high-performance servers due to their fast input/output characteristics. However, it is not well known how effective the energy efficiency of the AFA devices in the real world. This paper shows input/output performance and power consumption of the AFA devices measured on the Linux XFS file system via experiments and discusses energy efficiency of the AFA devices in the real world.

Enterprises need to monitor systems for reliable IT service operations to quickly detect and respond to events affecting the service, thereby preventing failures. Events in non-critical systems can be seen as a precursor to critical system incidents. Therefore, event relationship analysis in the operation of IT services can proactively recognize and prevent faults by identifying non-critical events and their relationships with incidents. This study used the Recurrent Neural Network and Long Short Term Memory techniques to create a model to analyze event relationships in a system and to verify which models are suitable for analyzing event relationships. Verification has shown that both models are capable of analyzing event relationships and that RNN models are more suitable than LSTM models. Based on the pattern of events occurring, this model is expected to support the prediction of the next occurrence of events and help identify the root cause of incidents to help prevent failures and improve the quality of IT services.

Objectives The purpose of this study is to examine the meaning of the Soeumin's Softness and Non-softness in the mouth(口中和, 口中不和). Methods We examined The Existing Doctors's using of the Softness and Non-softness in the mouth, and considered Jema Lee's using of the Softness and Non-softness in the mouth. Afterward, we considered the meaning of the Soeumin's Softness and Non-softness in the mouth in 『Donguisusebowon(東醫壽世保元)』. Results and Conclusion 1. Junggyeong Jang used the Softness in the mouth, and he didn't use the Non-softness in the mouth in 『Sanghanlun(傷寒論)』. 2. The Next Generation Doctors used the Softness in the mouth, and they didn't use the Non-softness in the mouth. Especially, Dongwon Lee used the Softness in the mouth as the Knowing the taste of food, and used the Non-softness in the mouth as the Non-knowing the taste of food. 3. Jema Lee used the Softness and Non-softness in the mouth as urgent indicator of the Soeumbyeong diarrhea in 『Gabobon(甲午本)』, and used the Softness and Non-softness in the mouth as classification indicator of the Taeeumbyeong and Soeumbyeong in 『Sinchuckbon(辛丑本)』. 4. The Non-softness in the mouth is Jema Lee's specific term. It means dry of mouth, thirsty and the Non-knowing the taste of food. 5. The change from the Non-softness to Softness in the mouth is recovery indicator of the Soeumin's disease. It is the basis for setting the Drinking water(能飮水) as the Soeumin's igiljeung(二吉證).

After CNN basic structure was introduced by LeCun in 1989, there has not been a major structure change except for more deep network until recently. The deep network enhances the expression power due to improve the abstraction ability of the network, and can learn complex problems by increasing non linearity. However, the learning of a deep network means that it has vanishing gradient or longer learning time. In this study, we proposes a CNN structure with MLP layer. The proposed CNNs are superior to the general CNN in their classification performance. It is confirmed that classification accuracy is high due to include MLP layer which improves non linearity by experiment. In order to increase the performance without making a deep network, it is confirmed that the performance is improved by increasing the non linearity of the network.
