Due to the large differences in human activity within classes, the large similarity between classes, and the problems of visual angle and occlusion, it is difficult to extract features manually, and the detection rate of human behavior is low. In order to better solve these problems, an improved Faster R-CNN-based detection algorithm is proposed in this paper. It achieves multi-object recognition and localization through a second-order detection network, and replaces the original feature extraction module with Dense-Net, which can fuse multi-level feature information, increase network depth and avoid disappearance of network gradients. Meanwhile, the proposal merging strategy is improved with Soft-NMS, where an attenuation function is designed to replace the conventional NMS algorithm, thereby avoiding missed detection of adjacent or overlapping objects, and enhancing the network detection accuracy under multiple objects. During the experiment, the improved Faster R-CNN method in this article has 84.7% target detection result, which is improved compared to other methods, which proves that the target recognition method has significant advantages and potential.

The software development life cycle (SDLC) is a procedure used to develop a software system that meets both the customer's needs and real-world requirements. The first phase of the SDLC involves creating a conceptual model that represents the involved domain in reality. In requirements engineering, building such a model is considered a bridge to the design and construction phases. However, this type of model can also serve as a basic model for identifying business processes and how these processes are interconnected to achieve the final result. This paper focuses on process modeling in organizations, per se, beyond its application in the SDLC when an organization needs further documentation to meet its growth needs and address regular changes over time. The resultant process documentation is created alongside the daily operations of the business process. The model provides visualization and documentation of processes to assist in defining work patterns, avoiding redundancy, or even designing new processes. In this paper, a proposed diagrammatic representation models each process using one diagram comprising five actions and two types of relations to build three levels of depiction. These levels consist of a static description, events, and the behavior of the modeled process. The viability of a thinging machine is demonstrated by re-modeling some examples from the literature.

In the developing country like India, groundwater is the main sources for household, irrigation and industrial use. Its contamination poses hydro-geological and environmental concern. The hazardous waste sites such as landfills can lead to contamination of ground water. The contaminants existing at such sites can eventually find ingress down through the soil and into the groundwater in case of leakage. It is necessary to understand the process of migration of pollutants through sub-surface porous medium for avoiding health risks. On this backdrop, the present paper investigates the behavior of pollutants' migration through porous media. The laboratory experiments were carried out on a soil-column model that represents porous media. Two different types of soils (standard sand and red soil) were considered as the media. Further, two different solutes, i.e., non-reactive and reactive, were used. The experimental results are simulated through numerical modeling. The percentage variation in the experimental and numerical results is found to be in the range of 0.75- 11.23 % and 0.84 - 1.26% in case of standard sand and red soil, respectively. While a close agreement is observed in most of the breakthrough curves obtained experimentally and numerically, good agreement is seen in either result in one case.

This study intends to investigate the impact of leadership style on civil servants' (in 4 ministries representatives of the Indonesian government) readiness to change and relocate to the future capital of Indonesia (Ibu Kota Nusantara / IKN). The quantitative approach was used from the data survey from 62 high-level civil servant representatives using a questionnaire. The collected data was analyzed using the SPSS software and exploratory factor analysis (EFA). The findings also indicated that, out of the 12 indicators of leadership style measured in this study, persuasion and integration leadership style should be considered crucial and important factors in shaping supportive behavior in the context of readiness for change. Making the relocation process successful requires avoiding the type of initiation structure leadership style. The finding of this study reveals that to choose the best leaders, the Indonesian government is urged to use these two criteria (persuasion and integration leadership style), especially for those in charge of facilitating the relocation process to IKN. Additionally, to demonstrate their confidence and make full use of their resources, leaders who are in command must be able to anticipate that the relocation of civil servants would go smoothly with less risk.

We meet many difficult challenges from many factors such as crime, natural disasters, social unrest, financial problems, employment, and so on. It therefore essential to cope with these negative stressful events to attain a state of personal well-being. Lately in the field of psychology and psychiatry, a concept called 'resilience' has received increasing attention. Resilience embodies the personal qualities that enable one to thrive in the face of adversity. Also it refers to the process of overcoming the negative effect of risk exposure, coping successfully with adversity, and avoiding the negative trajectories associated with risks. Resilience people were expected to do their innovative work behavior well. And SUS(supervisor support), COS(coworker support), OEMC(organizational error management culture) influence the relationship of resilience between Innovative Behavior. This study focused on three question. First, how is resilience relate to individual performance in the organization? And second, are there any moderate factors between resilience and individual performance. As the result of the hierarchical regression analysis, resilience indicates positive effects on IB and IB was predicted by interaction of resilience by SUS and OEMC. Findings in this study indicated that the level of SUS and OEMC should be considered in interpreting the resilience and Innovative Behavior.

Purpose - In recent years, research has been conducted on the conflict resolution strategies of the franchise headquarters and the franchisees, but there is a lack of research on the factors of conflict due to the intrinsic structure, such as interdependence or hierarchical relationship, and behavioral analysis to reduce the conflict. In this study, we analyze the relationship between satisfaction and trust formed in the process and result of the business, and the result of action to dissolution intention. Research design, data, methodology - For these purposes, the author developed the proposed model and several hypotheses. In this model, conflict resolution strategies consist of five dimensions such as avoiding, forcing, cooperating, obliging, and compromising strategy. And, this model proposed that onflict resolution strategies are antecedents of procedure quality, behaviour quality and dissolution intention are consequences of conflict resolution strategies. The data were collected from April 1 to April 15, 2013. Because this study examined franchise industries from the franchisee perspective, we contacted franchisee store owner and managers located in Seoul and Gyeonggi Province. Interviewers trained contacted a total of 483 franchisees, and 400 franchisees responded. Out of 400 respondents, 2 respondents were deleted due to missing information. Thus, a total of 398 franchisee were used for this study. he data were analyzed using frequency analysis, confirmatory factor analysis, correlation analysis, and structural equational modeling with SPSS 24.0 and Amos 23.0 statistical program. Results - The findings can be summarized as follows: First, franchisor conflict resolution activities have significant effects on procedure quality. Second, procedure quality has a significant effect on behavior quality. Finally, behavior quality has a significant effect on dissolution intention. Conclusions - In this study, we investigated the relationship between conflict resolution behavior, procedural quality, behavior quality and dissolution intention. As a result, the franchisers should strive to resolve conflicts not only in solving simple problems with franchisees, but also in a longer term perspective. We also found that the procedural aspects of resolving conflicts should not be ignored. If the trust and satisfaction of each other increase during the process of resolving the conflict, it will positively affect the satisfaction and trust in resolving the conflict. This is also because it serves to lower the intention of termination. However, there is a limitation that it is targeted only to the restaurant franchise, and it is necessary to study the conflict resolution behavior depending on the type of conflict.

Thrips are usually not exposed to insecticide spray due to hiding at holes, gaps, or crevices of host plants with their relatively small body sizes. This study devised a strategy to use a contact pheromone to suppress the seclusive behavior of the thrips, A contact pheromone identified as 7-methyltricosane (7TM) in the western flower thrips, Frankliniella occidentalis, was added to the diet to test the preference of the thrips. Although 7TM did not change the larval behavior, it significantly induced the avoiding behavior in male adults. In contrast, the contact pheromone was preferred by the female adults. Similar behavioral changes were also observed in another flower thrips, Frankliniella intonsa. Based on the behavioral changes induced by the contact pheromone, a mixture of 7TM and insecticide was applied to thrips infesting hot peppers in field conditions. Compared to spinetoram treatment, its mixture treatment with 7TM enhanced the control efficacy against thrips. Interestingly, 7TM treatment alone also gave slight reduction in F. intonsa density, suggesting a behavioral disruption of thrips by the contact pheromone. This study suggests a novel technology to control insect pests using contact pheromone by suppressing the seclusive behavior to avoid exposure to insecticide spray.

Long QT syndrome (LQTs) is a rare congenital disorder of the heart's electrical activity. Patients with LQTs are at increased risk of developing fatal ventricular arrhythmias. Elevated levels of sympathetic stimulation can exacerbate this risk. Successful behavior management is indispensable in the treatment of patients with LQTs. However, many drugs involved in pharmacologic behavior management are known to adversely affect the QT interval. Therefore, careful selection of a sedative drug is essential in avoiding such incidences. A 10-year-old boy with a known diagnosis of LQTs required restorative treatment due to dental caries at the permanent molar. He required sedation since treatment was painful and dental phobia can trigger sympathetic stimulation, creating a dangerous situation for patients with LQTs. Therefore, the treatment was performed over two sessions under moderate sedation involving propofol combined with nitrous oxide. Restorative treatment was successful without any complications under sedation with a target-controlled infusion (TCI) of propofol. There was no significant QT prolongation during pulpal treatment. Propofol TCI may be a good candidate for sedation in patients with LQTs.

PURPOSE: This study aimed to evaluate the effects of health-promoting behaviors on the subjective well-being of a physical therapist. METHODS: Survey data were collected from 247 physical therapists in Daejeon city. The baseline for health-promoting behaviors was determined using Health Promoting Lifestyle Profile (HPLP), subjective well-being was determined using Positive Affect and Negative Affect Schedule (PANAS), quality of life was measured using the SF-36 (Short-Form 36), and pain level was determined using the Quadruple Visual Analogue Scale (QVAS). Health-promoting behaviors and related factors were analyzed using an average comparative analysis (t-test), and the factors relevant to subjective well-being and health-promoting behaviors were evaluated using correlation analysis (Pearson's correlation coefficient). Factors affecting health-promoting behaviors were evaluated using stepwise multiple regression analysis (stepwise multiple regression). RESULTS: The mean score for health-promoting behavior was 3.73, with emotional support having the highest score (3.90) and regular meals having the lowest score (3.16 points; p<0.01). Health-promoting behavior was significantly correlated with positive emotions and negative emotions are subjective well-being, negative emotions and pain were noted (p<0.01). Health-promoting behaviors showed a significant correlation with quality of life (r=0.04), positive emotions (r=0.21; p<0.01), negative emotions (r=0.16; p<0.05), and pain level (r=0.016). The results of this study showed that health-promoting behaviors are significant predictors of subjective well-being in physical therapists (p<0.01). CONCLUSION: Physical therapists have to maintain their health by avoiding infections. Regular exercise is the most important factor among all health-promoting behaviors.

As an empirical study on the psychological side effects of using Social Networking Services (SNS), this study aims to identify the reality of negative emotion of using SNS and to predict its consequences. To this end, a measurement tool was developed through literature review, in-depth interview with users and expert review to induce negative emotional factors that can arise while using SNS. An exploratory factor analysis was performed for a total of 24 measurement items, which then were divided into the following 6 factors: 'concern over privacy,' 'burden from undesired connection,' 'relative deprivation,' 'a sense of alienation,' 'concern over reputation' and 'negative feeling about simple relationship.' Also, the relationship between the 6 negative emotional factors and psychological dissonance was analyzed. The results indicate that all the factors, except relative deprivation and a sense of alienation, affect psychological dissonance. It was also found that psychological dissonance, which implies a conflicting condition from using SNS, significantly affects the behavior that possibly reduces and limits the use of SNS. In other words, the users who have experienced psychological dissonance respond passively by avoiding the use of SNS to resolve the dissonance. The results of this study provide the base for explaining the psychological side effects of using SNS, which have been understood at a phenomenal level, such as 'Facebook depression' or 'SNS stress.' In addition, this study is of significance as it helps understand the psychological mechanism by identifying the relationship between negative emotion and use behavior with the theory of cognitive dissonance.
