This study aims to understand human nature in Daesoon Thought. In addition, it seeks to determine the characteristics of human nature and how the theory of human nature in Daesoon Thought relates to the direction of the Basic Works and the Three Major Societal Works of Daesoon Jinrihoe. In order to understand the theory of human nature in Daesoon Thought, I have classified various theories of human nature that appear in the Confucian tradition and have analyzed and reviewed them. I used this framework of types as a methodological criterion to study the theory of human nature found in Daesoon Thought. In Daesoon Thought, human nature is defined clearly as the conscience that is honest and truthful. Also, it accepts humans' basic biological needs, the pursuit of clothing, food, and sexual desires as part of human nature. This view can be evaluated as quite similar, although not perfectly consistent, with the theory of human nature posited by Wang Fuzhi (王夫之), who defined human nature as a combination of morality and biological desires. The theory of human nature in Daesoon Thought emphasizes human morality, but at the same time, it fully accepts that biological needs are basic elements of human life. In addition, it shows a characteristic that strongly implies a religious tendency as it recognizes that human nature is internalized through divine commands issued by the Supreme God of the Ninth Heaven (九天上帝 Gucheon Sangje), the transcendent and absolute ruler. The Basic Works of Daesoon Jinrihoe, which are Propagation, Edification, and Cultivation, aim to restore human nature to its innate state of honesty and truthfulness. Among the Three Major Societal Works, we can see that the works of Social Welfare and Charity Aid are implemented in accordance with the accepting acknowledgment of basic human needs (the pursuit of clothing, food, and sexual desires), and helping people meet their needs in appropriate ways and to appropriate degrees.

In recent years, the Television White Space (TVWS) has attracted the interest of many researchers due to its propagation characteristics obtainable between 470MHz and 790MHz spectrum bands. The plenty of unused channels in the TV spectrum allows the secondary users (SUs) to use the channels for broadband services especially in rural areas. However, when the number of SUs increases in the TVWS wireless network the aggregate interference also increases. Aggregate interferences are the combined harmful interferences that can include both co-channel and adjacent interferences. The aggregate interference on the side of Primary Users (PUs) has been extensively scrutinized. Therefore, resource allocation (power and spectrum) is crucial when designing the TVWS network to avoid interferences from Secondary Users (SUs) to PUs and among SUs themselves. This paper proposes a model to improve the resource allocation for reducing the aggregate interface among SUs for broadband services in rural areas. The proposed model uses joint power and spectrum hybrid Firefly algorithm (FA), Genetic algorithm (GA), and Particle Swarm Optimization algorithm (PSO) which is considered the Co-channel interference (CCI) and Adjacent Channel Interference (ACI). The algorithm is integrated with the admission control algorithm so that; there is a possibility to remove some of the SUs in the TVWS network whenever the SINR threshold for SUs and PU are not met. We considered the infeasible system whereby all SUs and PU may not be supported simultaneously. Therefore, we proposed a joint spectrum and power allocation with an admission control algorithm whose better complexity and performance than the ones which have been proposed in the existing algorithms in the literature. The performance of the proposed algorithm is compared using the metrics such as sum throughput, PU SINR, algorithm running time and SU SINR less than threshold and the results show that the PSOFAGA with ELGR admission control algorithm has best performance compared to GA, PSO, FA, and FAGAPSO algorithms.
Sound in the ocean is scattered by inhomogeneities of many different kinds, such as the sea surface, the sea bottom, or the randomly distributed bubble layer and school of fish. The total sum of the scattered signals from these scatterers is called reverberation. In order to simulate the reverberation signal precisely, combination of a propagation model with proper scattering models, corresponding to each scattering mechanism, is required. In this article, we develop a reverberation model based on the ray theory easily combined with the existing scattering models. Developed reverberation model uses (1) Chapman-Harris empirical formula and APL-UW model/SSA model for the sea surface scattering. For the sea bottom scattering, it uses (2) Lambert's law and APL-UW model/SSA model. To verify our developed reverberation model, we compare our results with those in Ellis' article and 2006 reverberation workshop. This verified reverberation model SNURM is used to simulate reverberation signal for the neighboring seas of South Korea at mid frequency and the results from model are compared with experimental data in time domain. Through comparison between experiment data and model results, the features of reverberation signal dependent on environment of each sea is investigated and this analysis leads us to select an appropriate scattering function for each area of interest.
In this paper, we propose a moving target localization algorithm using acoustic spectrograms. A time-versus-frequency spectrogram provide a information of trajectory of the moving target in underwater. For a source at sufficiently long range from a receiver, broadband striation patterns seen in spectrogram represents the mutual interference between modes which reflected by surface and bottom. The slope of the maximum intensity striation is influenced by waveguide invariant parameter ${\beta}$ and distance between target and sensor. When more than two sensors are applied to measure the moving ship-radited noise, the slope and frequency of the maximum intensity striation are depend on distance between target and receiver. We assumed two sensors to fixed point then form a circle of apollonios which set of all points whose distances from two fixed points are in a constant ratio. In case of three sensors are applied, two circle form an intersection point so coordinates of this point can be estimated as a position of target. To evaluates a performance of the proposed localization algorithm, simulation is performed using acoustic propagation program.
Due to technological advances, the cruising speed of high-speed trains is increasing, and aerodynamic noise generated from the flow outside the train has been an important consideration in the design stage. To accurately predict the flow-induced noise, high-resolution generation of sound sources in the near field and low-dissipation of sound propagation in the far field are required. This should be accompanied by a numerical grid and time resolution that can properly consider both temporal and spatial scales for each component of the real high-speed train. To overcome these challenges, this research simultaneously calculates the external flow and acoustic fields of five high-speed train cars of real-scale and at operational running speeds using a threedimensional unsteady Large Eddy Simulation technique. To verify the numerical analysis, the measurements of the wall pressure fluctuation and numerical results are compared. The Ffowcs Williams and Hawking equation is used to predict the acoustic power radiated from the high-speed train. This research is expected to contribute to noise reduction based on the analysis of the aerodynamic noise generation mechanism of high-speed trains.
We reevaluate the Burton equation (Burton et al. 1975) of predicting Dst index using high quality hourly solar wind data supplied by the ACE satellite for the period from 1998 to 2006. Sixty magnetic storms with monotonously decreasing main phase are selected. In order to determine the injection term (Q) and the decay time ($\tau$) of the equation, we examine the relationships between $Dst^*$ and $VS_s$, ${\Delta}Dst^*$ and $VS_s$, and ${\Delta}Dst^*$ and $Dst^*$ during the magnetic storms. For this analysis, we take into account one hour of the propagation time from the ACE satellite to the magnetopause, and a half hour of the response time of the magnetosphere/ring current to he solar wind forcing. The injection term is found to be $Q(nT/h)\;=\;-3.56VS_s$ for $VS_s$ > 0.5mV/m and Q(nT=h) = 0 for $VB_s\;{\leq}\;0.5mV/m$. The $\tau$ (hour) is estimated as $0.060Dst^*\;+\;16.65$ for $Dst^*$ > -175nT and 6.15 hours for $Dst^*\;{\leq}\;-175nT$. Based on these empirical relationships, we predict the 60 magnetic storms and find that the correlation coefficient between the observed and predicted $Dst^*$ is 0.88. To evaluate the performance of our prediction scheme, the 60 magnetic storms are predicted again using the models by Burton et al. (1975) and O'Brien & McPherron (2000a). The correlation coefficients thus obtained are 0.85, the same value for both of the two models. In this respect, our model is slightly improved over the other two models as far as the correlation coefficients is concerned. Particularly our model does a better job than the other two models in predicting intense magnetic storms ($Dst^*\;{< \atop \sim}\;-200nT$).
Travel choice behavior is affected by real-time traffic information. Recently, in urban area, real-time traffic information is provided by several instruments such as transportation broadcasting, internet PC network and variable message sign, etc. Furthermore, it has been increasing for urban travelers to use real-time traffic information provided by several instruments. The purpose of this study is to analyze the effects of advanced traveler information on urban worker's travel choice behavior. Among several Advanced Traveler Information System(ATIS) employed in urban area. This study focuses on examining the effects of transportation broadcasting on urban worker's travel choice behavior. This study attempts to examine traveler's mode change behavior in the pre-trip stage and traveler's route change behavior in the on-route stage. For this study, the survey data collected from Daegu City in 2000 is used. For empirical analysis, several nested logit models are estimated, and among them, the best models are reported in this paper.

This work proposes a 2-channel time-interleaved (T-I) 10b 120MS/s pipeline SAR ADC minimizing offset mismatch between channels without any calibration scheme. The proposed ADC employs a 2-channel SAR and T-I topology based on a 2-step pipeline ADC with 4b and 7b in the first and second stage for high conversion rate and low power consumption. Analog circuits such as comparator and residue amplifier are shared between channels to minimize power consumption, chip area, and offset mismatch which limits the ADC linearity in the conventional T-I architecture, without any calibration scheme. The TSPC D flip-flop with a short propagation delay and a small number of transistors is used in the SAR logic instead of the conventional static D flip-flop to achieve high-speed SAR operation as well as low power consumption and chip area. Three separate reference voltage drivers for 4b SAR, 7b SAR circuits and a single residue amplifier prevent undesirable disturbance among the reference voltages due to each different switching operation and minimize gain mismatch between channels. High-frequency clocks with a controllable duty cycle are generated on chip to eliminate the need of external complicated high-frequency clocks for SAR operation. The prototype ADC in a 45nm CMOS technology demonstrates a measured DNL and INL within 0.69LSB and 0.77LSB, with a maximum SNDR and SFDR of 50.9dB and 59.7dB at 120MS/s, respectively. The proposed ADC occupies an active die area of 0.36mm2 and consumes 8.8mW at a 1.1V supply voltage.

It is known widely that granulosa cell apoptosis leads follicular atresia and macrophages exert their effects directly and/or indirectly from the initiation to the completion of follicular atresia by phagocytosis of apoptotic bodies and secretion of various cytokines. However, the site of initiation, propagation routes and the elimination methods of apoptotic bodies, and the time and methods of penetration of macrophages into the follicles are not known completely. Using pig(Yorkshire-breed) ovary, immunohistochemical studies with TUNEL for apoptotic bodies and pig macrophage monoclonal antibody 4E9 for macrophages, and light and transmission electron microscopic observations were performed. In the pig, follicular atresia began with the granulosa cell apoptosis, and the apoptosis of theca intema cells occured at the same time. The apoptosis of granulosa cells initiated randomly within the granulosa cell layer and propagated rapidly into the whole layer. Ultrastructura1ly, apoptotic granulosa cells showed characteristic pyknotic and deformed nucleus and intracytoplasmic vesicles. Apoptotic bodies were eliminated by intact granulosa cells and macrophages. Intact granulosa cells ingested apoptotic bodies transiently, soon after they fell into the apoptosis. Finally, apoptotic bodies and degenerated oocyte were phagocytosed by macrophages. Macrophages entered the ovarian follicle at the time of initiation of granulosa cell apoptosis, and migrated with the progression of apoptosis. By elimination of theca cells, macrophages contributed the completion of follicular atresia These results will provide valuable informations on the study of the interrelation between macrophage and ovarian follicular atresia.
Studies on the rate of growth, the rate of feeding and the efficiency of food conversion on the stage of new-born fries to the near adult size for three species of cuttlefishes , Sepia esculenta, Sepia subaculeata, Sepiella maindroni and two species of squids, Sepioteuthis lessomiana, Euprymna berryi were carried out in the process of artificial raising, and then argued about a feasibility of the propagation of cuttlefishes and squids. 1. The relation between the daily age (D) and the body weight(W) of Sepia exculent is expressed in a logarithmic equation, log W=3.0649 log D-4.2768. The daily rates of growth through 121 days of the raising period were 1.46 per cent for the man시 length and 1.67 percent for the body weight. The raipidest growth of Sepia esculenta is observed at the stage of 1 to 4 cm in the mantle length . At that time the daily rates of growth reach 3.3 to 5.5 percent for the mantle length and 10.4 to 12.0 percent for the body weight, respectively. The growth of Sepia esculenta varies a great deal to the bait. When fed on a dead bait the rates of growth decrease 17 per cent for the mantle length and 26 percent for the body weight compared with those fed on a live bait. 2. The relation between the daily age and the body weight of Sepia subaculeata is expressed in a logarithmic equation, log W=3.7447 log D-4.9003. The daily rates of growth through 110 days of the raising period were 1.63 percent for the mantle length and 1.83 percent for the body weight. The rapidest growth of Selia subaculeata is observed at the stage of 1.5 to 9.0 cm in the mantle length. At that time the daily rates of growth reach 3.1 to 7.4 percent for the mantle length and 6.8 to 16.7 percent for the body weight , respectively. 3. The relation between tehdaily age and the body weight of Sepiella maindroni is expressed in a ogarithmic equation , log W=2.9332 log D-3.8224 . The daily rates of growth through 133 days of the rearing period were 1.39 percent for the mantle length and 1.51 percent for the body weight . The rapidest growth of Sepiella maindroni is observed at the stage of 0.4 to 5.8 cm in the mantle length. At that time the daily rates for growth reach 4.6 to 7.3 percent for the mantle length and 8.5 to 15.4 percent for the body weight , respectively. 4. The daily rates of growth onthe stage of 0.5 to 6.0 comin the mantle length of Sepioteuthis lessoniana were 4.1 to 5.9 percent for the mantle length and 7.1 to 10.7 percent for the body weight . 5. During the rearing period of 31 days immediately after the hatching , the daily rateof feeding of Sepia esculenta marked 11.0 to 39.4 percent (28.2 percent in an average), and the efficiency of food conversion of this species reached 9.0 to 71.0percent (38.7percent in an average). Even at the more growing stage of 4.5to 6.2 cm in the mantle length, the daily rate of feeding of three species of cuttlefishes wee maintained 17.7 percent for Sepia esculenta, 30.8 percent for Sepia subaculeata and 34.7percent for Sepiella maindroni on an average. 6. The efficiency of food coversion of cuttlefishes and squids are larger than those of other fishes, and all the species are rapid in their growth. Four to five months are thought to be enough for their growing into a fair commercial size.
