The open circuit voltage (OCV) is widely used to estimate the state of charge (SOC) in many estimation algorithms. However, the relationship between the OCV and SOC can not be exactly same for all batteries. Because the conventional OCV-SOC differs between batteries, there is a problem that the relationship of the OCV-SOC should be measured to accurately estimate the SOC. Therefore, the conventional OCV-SOC is modified to a new relationship in this paper. Thus, problems resulting from the defects of the extended Kalman filter (EKF) can be avoided by preventing the relationship from varying. In this paper, SOC and capacity of the lithium-ion battery are estimated using the dual EKF with the proposed method.

In order to promote foodservice for the elderly, foodservice managers in Continuing Care Retirement Communities (CCRCs) must identify the main factors to enhance the satisfaction and behavioral intentions with food service. The purpose of this study was to investigate the relationships between relationship quality (consisting of trust, commitment, and satisfaction) and communication in the formation of elderly's behavioral intentions with food services at CCRCs. A survey was administered to residents in two CCRCs and a total of 327 residents participated. A tested structural equation model exhibited good model fit and explanatory power of the study construct. Satisfaction directly influenced word-of-mouth and service quality has an influence on commitment. Commitment was a significant determinant of behavioral intentions to eat more often in the dining room. Also, communication showed positive association with trust. The results provided strong evidence for the importance of satisfaction and communication as a consequence of relationship marketing efforts. Suggestions for future research to better understand the elderly' behavioral intention judgments were given.

Objectives: This study was conducted to investigate the effect of self-control and interpersonal relationship satisfaction on department satisfaction among dental hygiene students. Methods: A survey was conducted on 306 dental hygiene students from Seoul, Gyeonggi, Chungcheong, Jeolla, and Gyeongsang. Results: The factors affecting college department satisfaction of dental hygiene students were interpersonal relationship satisfaction (β=0.609), volunteer activities_dummy 1 (No/Yes) (β=0.131), and year_dummy 3 (1/4) (β=0.128). The most deterministic factor was interpersonal relationship satisfaction with the explanatory power of 37%. Conclusions: Based on these results, it is thought that research on department satisfaction needs to be actively conducted to develop adequate measures and programs to enhance department satisfaction of students.

By analyzing the film context and taking the film "Blind Mountain", which adapted from a real event in China, as a template, this article aims to analyze the relationship between this type of film and the society from the characteristics of the film adapted from the real event and the relationship with the society after being adapted to films. From the perspective of characteristics, the author also analyzed that firstly, the interactive relationship of presentation is the film's exposure of the real "ugliness" and the perception of "beauty" in the real society. Secondly, the supporting interactive relationship not only enriches the social experience of film creators, but also enhances the film's ability to re-news. Thirdly, the pressure-type interaction is not only to regulate the power of social behavior, but also to promote the intangibility of social thought.

This study examines the relationship between intrinsic motivation and individuals' performance in the Republic of Korea armed forces and explores whether job stress mediates the relationship between intrinsic motivation and individuals' performance. The research questions are: (1) Does intrinsic motivation influence individual performance in military organizations? (2) Does job stress impact individual performance? and (3) Does job stress mediate the relationship between intrinsic motivation and individual performance? The study utilizes data collected from a 350 soldiers survey in the Special Forces Brigade and Special Assault Commando Regiment of the Republic of Korea's Army. We use structural equation modeling (SEM) to explore the mediation role among intrinsic motivation, job stress, and individuals' performance. Research findings suggest that intrinsic motivation negatively impacts job stress. We also find that job stress has a positive effect on firearm skills. Moreover, the study reveals that the relationship between intrinsic motivation and firearm skills is partially mediated by job stress.

This study aims to examine the subjects of cultural power of the modernism and post modernism eras, and analyze how the change of power and subjects influenced fashion throughout the history from the microscopic perspective, and thus to explain the social relationship of the fashion phenomenon. The study findings can be summarized as follows. First, as the post modernism era which was being formed centering around Europe that was pursuing Haute Couture and formal masculine suits ended and the post modernism era started, America became the center of the world power, and the American equalitarianism and growing wealth among the general public spread over the world, and as a result, the ready-made clothes were propagated over the world, and various subcultures came to have multi-national tendency in the New Media society. Second, in the modernism era, the high class, whites, males, and the pre-existing powerful class were the subjects of cultural power. Although this changed in the post modernism era, as some of power moved from the high class to the middle class, the economically affluent general public, still the western world, males, and whites held the center of power. However, later, females, youths, the third world nations, and so on emerged as minor power, and when the New Media society started, the structure developed so that everyone can share cultural power.

The Water usage is relationship which is close with the administrative cost from industrial facility. It is not easy to reduce a water usage. This research is the optimization of the waste water quantity which process waste water integration of the standard thermal power plant in system operate time. The turbine rotates by force of the steam and it produces an electricity. Demineralization Water is manufacture purity manufacturing equipment and it is supplied in power plant channel. We knew a possibility of reducing from pure control process. When it is reduced the Back Washing time, Rinsing time of the gravity filter and the activated carbon filter. Also, It is possible even from regeneration phase in Condensate Polishing Demineralization System. In addition, There is also the water which the drain of the sampling water for watching the condition of power plant process will be able to use. Integrates these processes it will be able to reduce an annual 30,000 ton degree. The research is want to use the fundamental data for the water curtailment of the power plant.

With power level of grid-connected converters rising, the switching frequency of the switching devices is commonly greatly reduced to improve its power capacity. However, this results in serious couplings of the dq current components, which leads to degradation of the static and dynamic performances of grid-connected converters and fluctuations of the reactive power in dynamic processes. In this paper, complex vector models under low switching frequency are established for an L/LCL grid-connected converter, and the relationship between the switching frequency and the coupling degree is analyzed. In addition, a series decoupling current control strategy is put forward. It is shown that the proposed control strategy can eliminate the couplings, improve the performances and have good robustness to parameter variations through static and dynamic characteristics analyses and a sensitivity analysis. Experimental and simulation results also verify the correctness of the theoretical analyses and the superiority of the proposed control strategy.
