As the power grids are integrated into one big umbrella called a "smart grid," communication protocol plays a key role in successful operations. The successful deployment of smart grid interoperability is a major hurdle that must be overcome. The micro grid, a small power system that distributes energy resource, is operated in diverse regions. Different vendors use different communication protocols in the operation of the micro grid. Recently, the IEC 61850 has been legislated to solve the interoperability problems in power utility automation. The present paper presents a micro grid system based on the IEC 61850 protocol. It consists of a micro grid monitoring system, a protocol converter that transforms serial data to IEC 61850 data, and distributed energy resource controllers for diverse DER nodes. A developed communication gateway can be deployed for DER controllers with serial links to exchange data with IEC 61850-based devices. The gateway can be extended to IEC 61850-based distribution automation systems, substation automation systems, or SCADA.

Pre-reinforcement with umbrella arch grouting is conducted around a tunnel where a portion of the upper part of the tunnel is located in a sand and gravel layer. Surroundings of a first tunnel situated below groundwater table are reinforced with LW or SSM that is composed of ultra-fine cement and injected into multi-stages through large diameter steel pipes. With them, a first tunnel is safely excavated without both leaking of groundwater and fallings of sand and gravel from the arch. A second tunnel where groundwater is drained down to the bedrock is reinforced with jet grouting. The effect of the pre-grouting reinforcement is monitored by checking whether groundwater is dripping or sand or gravel is falling from the arch of the tunnels.

Chronic orofacial pain is an umbrella term as a kind of painful regional syndromes to describe unremitting and prolonged pains in orofacial area. It is frequently characterized with the intractable pain without the proportionally corresponding tissue pathology over 3 months. Accordingly, it is difficult or almost impossible to establish the causally oriented treatment strategies in those cases, while multidisciplinary approaches were usually considered for preventing prolonged pain conditions from limiting daily life. Among a variety of approaches, pharmacological approach was clinically based on proper applications of several groups of drugs useful to relieve or alleviate pain. These drugs usually encompass several analgesics, muscle relaxants, anti-depressants, anticonvulsants and so on. Therefore, it is essential for dental clinician to be aware of the many peculiarities of these medications applied for management of chronic orofacial pain disorders. This review focused on the clinical considerations for the careful drug selection and application including dosages and adverse drug reactions.

Open Science is an umbrella term that involves various movements aiming to remove the barriers to sharing any kind of output, resources, methods or tools at any stage of the research process. While the study of open science is relatively advanced in Western countries, we know of no scholarship that attempts to understand open science in Hong Kong. This paper provides a broad-based background on the major research data management organisations, policies and institutions with the intention of laying a foundation for more rigorous future research that quantifies the benefits of open access and open data policies. We explore the status and prospects for open science (open access and open data) in the context of Hong Kong and how open science can contribute to innovation in Hong Kong. Surveying Hong Kong's policies and players, we identify both lost research potential and provide positive examples of Hong Kong's contribution to scientific research. Finally, we offer suggestions regarding what changes can be made to address the gaps we identify.

Head and neck cancer is the 6^th most frequently diagnosed solid tumor in the world. Alcohol consumption, smoking, and HPV infection are associated with the incidence of head and neck squamous cell carcinoma (HNSCC). Although a multidisciplinary approach is a key strategy for the treatment of locally advanced HNSCC, systemic therapy is the mainstream of recurrent or metastatic HNSCC treatment. Stage IV HNSCC has a relatively poor prognosis with median overall survival of around one year. There have been many clinical trials to investigate the efficacy of target agents in the treatment of HNSCC. In the HPV-negative HNSCC, TP53 and CDKN2A are the most commonly mutated genes. In the HPV-positive HNSCC, the PI3K pathway is frequently altered. EGFR, PI3K, cell cycle pathway, MET, HRAS, and IL6/JAK/STAT pathway are explored targets in HNSCC. In this study, we review the target pathways and agents under research. We also introduce here umbrella trials of recurrent or metastatic HNSCC conducted by the Korea Cancer Study Group. The combination of target agents with immune checkpoint inhibitors or cytotoxic chemotherapies would be a future step in the precision medicine of HNSCC treatment.

This article aims to examine the concept and historical background of Applied Theatre and its major characteristics as a newly emerging theatrical practice in recent years. With these aims, the article chronicles the history of how Applied Theatre has developed and formed as an overarching umbrella term that encompasses different theatrical praxis. Given the ambiguity and confusion of this practice, the article argues the importance of recognizing the Applied Theatre's shifting paradigm of subject and object, a crucial element in understanding the practice. Further discussed is the exploration of 'community' in regards to comparing the similarities and differences among Applied Theatre, Community Theatre, and Community-based Performance. The article concludes that the essential comprehension of Applied Theatre's uniqueness comes from noticing and perceiving the paradigm shift that places participants and community as a subject of theatrical transaction rather than as an object, as traditional theatre has done so far.

Social networking sites (SNSs) have become an essential part of people's lives. It is thus crucial to understand how individuals use these platforms. Previous literature has divided usage into numerous activities and then grouped them into dimensions to avoid excessive granularity. However, these categories have not been derived from a uniform theoretical background; consequently, these dimensions are dispersed, overlapping, and disconnected from each other. This study argues that "SNS usage" is a complex phenomenon consisting of multiple activities that can be grouped into dimensions under the umbrella of communication theories and these dimensions are related to each other in a particular multi-dimensional architecture. "SNS usage" is conceptualized as a third-order construct formed by "producing," "consuming," and "communicating." "Producing," in turn, is proposed as a second-order construct manifested by "commenting," "general information sharing," and "self-disclosure." The proposed model was assessed with data collected from 414 USA adult users and PLS-SEM technique. The results show empirical support for the theorized model. SNS providers now have this architecture that clarifies the role of each dimension of use, which will allow them to design effective strategies to encourage the use of these networks.

Acute respiratory distress syndrome (ARDS) is a common cause of severe hypoxemia defined by the acute onset of bilateral non-cardiogenic pulmonary edema. The diagnosis is made by defined consensus criteria. Supportive care, including prevention of further injury to the lungs, is the only treatment that conclusively improves outcomes. The inability to find more advanced therapies is due, in part, to the highly sensitive but relatively non-specific current syndromic consensus criteria, combining a heterogenous population of patients under the umbrella of ARDS. With few effective therapies, the morality rate remains 30% to 40%. Many subphenotypes of ARDS have been proposed to cluster patients with shared combinations of observable or measurable traits. Subphenotyping patients is a strategy to overcome heterogeneity to advance clinical research and eventually identify treatable traits. Subphenotypes of ARDS have been proposed based on radiographic patterns, protein biomarkers, transcriptomics, and/or machine-based clustering of clinical and biological variables. Some of these strategies have been reproducible across patient cohorts, but at present all have practical limitations to their implementation. Furthermore, there is no agreement on which strategy is the most appropriate. This review will discuss the current strategies for subphenotyping patients with ARDS, including the strengths and limitations, and the future directions of ARDS subphenotyping.

Paragangliomas are rare neuroendocrine tumors that are usually benign in nature. They may be either familial or sporadic in their occurrence. Numerous neuroendocrine tumors are collectively included under the umbrella of paragangliomas. Among them, carotid body tumors and glomus jugulare tumors are extremely rare. Thus, we present a rare case of 29-year-old male who was admitted with hearing difficulties and tinnitus in the left ear, with swelling on the left side of the neck. Based on clinical and radiological findings, a diagnosis of left-sided glomus jugulare with carotid body tumor was made. The patient underwent a two-stage surgery with an interval of approximately 2 months. Histopathology revealed a paraganglioma. Herein, we present the clinical features, imaging findings, management, and a brief review of literature on the classification, evaluation, and management of carotid body and glomus jugulare tumors. Paraganglioma is a slow-growing tumor. The synchronous occurrence of carotid body and glomus jugulare tumors is infrequent. Microsurgical resection remains the primary treatment modality. Therefore, our patient underwent two-stage surgery. The rarity of occurrence and the proximity and adherence to vital neurovascular structures have resulted in the treatment of paragangliomas remaining a challenge.
