It is necessary to control the room temperature for comfortable and deep sleep during a tropical night. We need to investigate thermal transport and parameter between human and environment for comfortable sleep. Therefore this study is performed to evaluate the comfortable room temperature based on the change of skin temperature under variations in thermal conditions and several reports. Five female subjects of 20~22 years with similar sleeping pattern were participated for the experiment. The subjects arrived in chamber at 9 pm and adapted to thermal circumstances during 2 hours. The sensors was sticked in body for skin temperatures. If subjects fall asleep in chamber, lights off and then sleep during 8 hours.As results, indoor temperature range for comfort sleep was $23.9{\sim}28.4^{\circ}C$ based on comfort mean skin temperature. But considering transition of time, minimum indoor temperature was $21.6^{\circ}C$, $22.9^{\circ}C$, $24.1^{\circ}C$, $23.9^{\circ}C$ and maximum indoor temperature was $28.2^{\circ}C$, $30.1^{\circ}C$.

In this paper, I will argue that in teaching L2, it is important to take a holistic teaching method considering various learning styles of the learners and the nature of L2 learning. Under the situation that most of the school education is centered on the left brain activity, learners with the right brain preference tend to get only to the lower proficiency than they really can. To prove this, I conducted a experiment on two classes of high school students. I decided the hemispheric preference of each students using HMI (hemispheric mode indicator) Then I compared the hemispheric preferences of students with their scores in English tests. The students with right hemispheric preference show significantly lower scores than the ones with left preference. It is implied that the current English education should adapted to address various learning and cognitive styles and whole-brain L2 teaching method should replace the left-centered instruction in the learning environment.

Whales are marine mammals that are fully adapted to aquatic environment. Whales breathe by lungs so they require adaptive system to low oxygen concentration (hypoxia) while deep and prolonged diving. However, the study for the molecular mechanism underlying cetacean adaptation to hypoxia has been limited. Hypoxia-inducible factor (HIF) is the central transcription factor that regulates hypoxia-related gene expression. Here we identified HIF-binding sites in whale genome by phylogenetic footprinting and analyzed HIF-target genes to understand how whales cope with hypoxia. By comparison with the HIF-target genes of terrestrial mammals, it was suggested that whales may retain unique adaptation mechanisms to hypoxia.

More new devices and technologies are recently adapted on homes to aim at enhancing our lifestyle. But though they are not interconnected each other but controlled separately. To solve this problem, we have designed and implemented a common prototype based on openHAB and RaspberryPi they could speak to each other to create a really automated and smart environment at home. The proposed prototype can merge the existing variable devices, add and remove new features at runtime because of its modular design. The proposed prototype based on a low-cost platform showed its potential as a smart home and provide a new UX to users.

To make provision for the super-aged society, the senior welfare facility which is a kind of typical physical environment of the nursing service would be expected to perform a very important role in local community. This study was conducted to identify the constructs of the servicescapes of senior welfare facility and to draw analysis indicators of it. For this, we performed literature review based on domestic & foreign government guide, service marketing theory and interior architectural results concerning the physical environment of the senior welfare facility. The result of this study showed as follows: servicescapes of the senior welfare facility could be explained as "a whole set of physical environment to support a variety of services provided by the senior welfare facility for the elderly or services of the kind of tangible clues". Analysis indicators of the senior welfare facility's servicescape could be explained as five factors: safety factor, functional factor, aesthetic factor, ambient factor and social factor. In addition we developed 37 pieces of detailed factors referred to five factors. The evaluation and verification of analysis indicators was carried out through 8 experts in-depth interviews. We inspected importance factor using a 5-point Likert scale, therefore safety factor was 4.41, functional factor was 4.27, aesthetic factor was 3.66, ambient factor was 4.20 and social factor was 4.25. More than anything else, in this study, there is a sense that it has established the concept of servicescape adapted to the senior welfare facility and contained a social element between the employees and the physical environment. Theoretical and practical implications of findings are discussed, and future research directions are proposed. we expect to be a little or benefits to the senior welfare facility corresponding to the future of the super-aged society.

Globally road transport networks are subjected to continuous levels of stress from increasing loading and environmental effects. As the most popular mean of transport in the UK the condition of this civil infrastructure is a key indicator of economic growth and productivity. Structural Health Monitoring (SHM) systems can provide a valuable insight to the true condition of our aging infrastructure. In particular, monitoring of the displacement of a bridge structure under live loading can provide an accurate descriptor of bridge condition. In the past B-WIM systems have been used to collect traffic data and hence provide an indicator of bridge condition, however the use of such systems can be restricted by bridge type, assess issues and cost limitations. This research provides a non-contact low cost AI based solution for vehicle classification and associated bridge displacement using computer vision methods. Convolutional neural networks (CNNs) have been adapted to develop the QUBYOLO vehicle classification method from recorded traffic images. This vehicle classification was then accurately related to the corresponding bridge response obtained under live loading using non-contact methods. The successful identification of multiple vehicle types during field testing has shown that QUBYOLO is suitable for the fine-grained vehicle classification required to identify applied load to a bridge structure. The process of displacement analysis and vehicle classification for the purposes of load identification which was used in this research adds to the body of knowledge on the monitoring of existing bridge structures, particularly long span bridges, and establishes the significant potential of computer vision and Deep Learning to provide dependable results on the real response of our infrastructure to existing and potential increased loading.
