Development of Smart Home Gesture-based Control System

Sensors and Materials (2021)

Rong-Jing Wang Shu-Chen Lai Ji-Yun Jhuang Ming-Chin Ho Yan-Chyuan Shiau

In recent years, smart speakers have been widely used to control related smart home appliances.For people with speech disabilities, smart speakers cannot be used to perform related voice control tasks.To help people with speech difficulties and effectively control related smart facilities, we use the Internet of Things to develop a smart home gesture-based control system.The prototype of the system is established by means of sensors and a control panel system.When a sensor detects a control gesture command, it can send related control signals to a controlled smart device.The controlled devices used in this study include smart home appliances such as doors and windows, air conditioners, curtains, dehumidifiers, and air purifiers.The system functions include the opening/closing of doors, windows, and curtains; the activation/ deactivation of heating and cooling systems, dehumidifiers, and air purifiers; temperature and humidity adjustment; and fan operation.With the development of this system, it is possible for people with language disabilities and elderly people to control the operation of various smart devices with gestures.It can also solve the inconvenience of needing to look for remote controls for various facilities.Moreover, it can save precious time and provide a safe, convenient, and smart home living environment for people with speech disabilities.

Residual Seismic Capacity of UHPC Columns After Fire Exposure

Chung‐Chan Hung Bo-Jun Huang Rong-Jing Wang Shun-Chih Wang Ming‐Yuan Lei

The seismic behavior of UHPC columns after fire exposure was experimentally investigated. The experimental program contained six concrete column specimens reinforced with high-strength reinforcing bars, including two normal-strength concrete (NSC) columns, two high-strength concrete (HSC) columns, and two UHPC columns. For each type of the columns, one column was subjected to a 2-hour fire exposure according to the standard heating condition while the rest of the columns were considered as control specimens without exposure to fire. To investigate the fire effect on the seismic performance, all column specimens were subjected to lateral displacement reversals with a constant axial load. The test results show that for the NSC and HSC columns, the lateral strengths after fire exposure were reduced by 7.8% and 13%, respectively. Moreover, the effective stiffnesses degraded by 48% and 55%, respectively. While the 2-hour fire exposure had relatively minor effect on the lateral strength of the concrete columns, it considerably reduced the stiffness of the columns regardless of the type of concrete materials. The seismic capacity of the UHPC column after fire exposure was discussed extensively in terms of the damage pattern due to fire exposure, residual strength and stiffness, energy dissipation capacity, and failure mode.

Contact-Free Operation of Epidemic Prevention Elevator for Buildings

Buildings (2022)

Shu-Chen Lai Hsin-Hsou Wu Wei-Ling Hsu Rong-Jing Wang Yan-Chyuan Shiau

The COVID-19 pandemic broke out in early 2020, and the infection rate of COVID-19 variants is considerably higher than that of the original virus. The pandemic is still spreading globally. In June 2021, two families living on different floors of a building in Fongshan, Kaohsiung, were simultaneously infected with COVID-19. Investigation results suggested that an elevator in buildings was the most likely place where the virus transmission occurred. Building elevators are a necessary vertical transportation facility for residents or workers in high-rise buildings, and people touch elevator buttons while operating elevators. When a passenger carrying the virus touches elevator buttons, subsequent passengers may be easily infected if they touch those buttons and then touch their mouth, eyes, or nose by accident before sanitizing or washing their hands. In this study, we developed a contact-free elevator ride system by applying smart speech recognition, contact-free perceptual buttons, gesture recognition sensors, and a web page browser activated by quick response codes to operate an elevator. This system reduces the risk of virus infection caused by contact during an elevator ride, effectively enhancing pandemic prevention and protecting people’s health.

Construction Cost of Green Building Certified Residence: A Case Study in Taiwan

Sustainability (2019)

Chen-Yi Sun Yin-Guang Chen Rong-Jing Wang Shih-Chi Lo Jyh-Tyng Yau

The green building certification system of Taiwan, EEWH (Ecology, Energy Saving, Waste Reduction and Health), has been in operation for more than 20 years (since 1999). In order to understand the relationship between green building certification and the construction costs of residential buildings, this study obtained 37 green building-certified residential cases and 36 general residential cases available from public information and conducted a comparative analysis. The results of this study showed that the average construction cost of a green building certification residential building was only 1.58% higher than a general residential building, indicating that green building certification does not require a large increase in costs. However, for residential buildings, achieving a high-grade (gold-grade or diamond-grade) green building certification means an increase of 6.7% to 9.3% in construction costs. This shows that the pursuit of higher levels of green building certification does require higher construction costs. In addition, the results of this study can not only provide important references for the government in making green building policies, but also offer a practical strategy for developers for decision-making.

Remote-control System for Elevator with Sensor Technology

Sensors and Materials (2022)

Shu-Chen Lai Ming‐Ling Yang Rong-Jing Wang Ji-Yun Jhuang Ming‐Chih Ho

Elevators are essential in high-rise buildings.Their principle is simple but they have many devices and functions for safe operation and effective management.The development of new technologies based on the Internet of Things (IoT) and high-rise building technology allows improved elevator systems with remote control and intelligent operation.Many studies have proposed new functions for safety management, efficient operation, and effective data collection and storage.However, remote-control technology is required for advanced elevator systems, especially those based on recent technologies such as the IoT and sensor technology.Therefore, a study was carried out to provide the required basic information on what should be sensed, which sensors should be used, and where they should be installed in a remote-control elevator system.For this study, we designed a questionnaire to define the issues with the help of experts.The replies to the questionnaire were analyzed using the Delphi method, and the results suggest that 18 major tasks must be performed when designing an elevator system appropriate for remotecontrol and intelligent operation.We propose the monitoring items, related sensors or devices, and their installation locations for an intelligent elevator system.A design based on the results of this study is expected to contribute to the development of an improved intelligent and remotecontrol elevator system.The results enable subsequent research on the technological requirements of the equipment and the establishment of maintenance and management strategies for the proposed elevator system.

PI3Kα inhibitor CYH33 triggers antitumor immunity in murine breast cancer by activating CD8⁺T cells and promoting fatty acid metabolism

Journal for ImmunoTherapy of Cancer (2021)

Pu Sun Xi Zhang Rong-Jing Wang Qingyang Ma Lan Xu

Background The phosphatidylinositol 3-kinase (PI3K) is frequently hyperactivated in cancer and plays important roles in both malignant and immune cells. The effect of PI3Kα inhibitors on the tumor microenvironment (TME) remains largely unknown. Here, we investigated the modulation of the TME by a clinical PI3Kα-specific inhibitor CYH33. Methods The activity of CYH33 against a panel of murine tumors in the immune-competent context or athymic mice was detected. Single-cell RNA sequencing and multi-parameter flow cytometry were performed to determine the immune profiling of TME. The effect of CYH33 on immune cells was conducted with primary murine cells. Results CYH33 exhibited more potent antitumor activity in immune-competent context. CYH33 enhanced the infiltration and activation of CD8 + T and CD4 + T cells, while attenuating M2-like macrophages and regulatory CD4 + T cells. Increase in memory T cells was confirmed by the induction of long-term immune memory on CYH33 treatment. Mechanistically, CYH33 relieved the suppressed expansion of CD8 + T cells via preferential polarization of the macrophages to the M1 phenotype. CYH33 promoted fatty acid (FA) metabolism in the TME, while FA enhanced the activity of CD8 + T cells in vitro. The combination of CYH33 with the FA synthase (FASN) inhibitor C75 synergistically inhibited tumor growth with enhanced host immunity. Conclusions CYH33 induces immune activation and synergizes with FASN inhibitor to further promote the antitumor immunity, which gains novel insights into how PI3K inhibitors exert their activity by modulating TME and provides a rationale for the concurrent targeting of PI3K and FASN in breast cancer treatment.
