As a result of the global effect of infectious diseases like COVID-19, remote patient monitoring has become a vital need. Surgical ICU monitors are attached around the clock for patients in critical care. Most ICU monitor systems, on the other hand, lack an output port for transferring data to an auxiliary device for post-processing. Similarly, strapping a slew of wearables to a patient for remote monitoring creates a great deal of discomfort and limits the patient's mobility. Hence, an unique remote monitoring technique for the ICU monitor's physiologically vital readings has been presented, recognizing this need as a research gap. This mechanism has been put to the test in a variety of modes, yielding an overall accuracy of close to 90%.

Since the first BIM development outline was issued in 2011, China has initially tried to adopt BIM in the construction industry. After the BIM guide was issued in 2017, China has officially entered the era of building informatization in the construction industry. Through the statistical data of BIM application reports in China's construction industry from 2014 to 2020, this paper concludes that China has made great progress in the popularization rate of BIM, but has little effect in the adoption in actual projects. Through the reading and analysis of relevant documents in China, 13 obstacle factors for BIM technology adoption in construction enterprises are preliminarily defined.

In this paper, we study the effect of writing activity as mathematical communication on the students's mathematics achievement, learning attitude, and mathematical tendency. For this purpose, we construct a experimental class and then analyze the students' change in those aspects after applying three-divided-note writing activity and colleague feedback on their works those students are in the experimental class. As a result of the experiment, we find that three-divided-note writing activity and colleague feedback made some significant changes on the students achievement in mathematics, learning attitude, but does not affect on mathematical tendency. We also offer some suggestions for further research. Firstly, the mathematical communication ability must be stressed in mathematics education. For this purpose, we need to develop the teaching and the evaluation method to use not only writing but also reading, speaking, and listening skills so that many teachers can apply this method easily to their classes. Second, we need to fix some realistic problems such as fair evaluation , the numbers of students per class, the numbers of lesson, and too much extra-work, and so on. Thirdly, we suggest to explore some methods for extending three- divided-note writing activity to evaluate mathematical essay and to study educational effects of colleague feedback on mathematics performance assessment.

This research tries to find out the effect bibliotherapy has upon the stress of college students in the process of self-formation. Actually, bibliotherapy was carried out in the Library of S College for eight weeks and the stress college students undergo in the process of self-formation having been studied closely, a paired t-test has been carried out in order to compare the. difference between the stress levels of the students after bibliotherapy and those before the therapy. The result shows that bibliotherapy had been notably effective in decreasing the students' stress in the process of self-formation. Therefore, it is suggested that college libraries need to inform their students of bibliotherapy and to develop various programs to promote it.

This study developed and evaluated a school adjustment program for children from multi-cultural families. The program was developed to enhance Korean language ability and adjustment to school for children from multi-cultural backgrounds. 14 preschool children (5 boys and 9 girls) participated in this program. The effect of this program was assessed through a preschool-children's receptive and expressive vocabulary test as well as through a reading ability test. Results showed there was a significant experimental effect (p<.05) in receptive and expressive vocabulary test scores. After the experiment, children showed higher scores in the receptive and expressive vocabulary test than before. Results of the program evaluation revealed this program was helpful for promoting Korean language ability in children and assisted their adjustment to school for children from multi-cultural backgrounds.

By understanding the construction process of sea dikes and the current state of the thickness and speed of fluid in the bottom layer protection work of final closure gaps, a construction method applicable for the blocking of bottom layer work will be selected. The three construction methods selected will be tested in site through various methods, and the reinforcement of bottom layer protection and impervious effect will be verified. The verification results are as follows: 1) The overall riprap layer were 0.5~1.0m thicker than planned so that the grouting depth and grout input amount increased 2) The applied construction methods permeability of riprap layers were improved from $\alpha{\times}10^{-2}cm/s$ before the construction to $\alpha{\times}10^{-4}cm/s$ after construction. 3) The results of core extraction in order to grossly verify the hardening time and durability allowed the identification of grout injection effect. The amount of filling of the injection was difficult to judge because the slime in many areas made the reading of borehole photography difficult.

Robot programming often sparks students' interest in programming, but it is not easy for them to program both procedure and reactivity of robot movements that are essential requirements. In this study, we reviewed in detail a new programming language, State-Based Squeak. It allows novice students to implement both procedure and reactivity of robots easily. The effect of this new language on robot programming education was also examined using a group of 28 middle school students. According to the results of analyzing the students' understanding of programming, reading and programming abilities the group that used State-Based Squeak (the experimental group) showed a higher completion ratio than the other (control) group. The significance of this study is that a robot programming language has been developed that addresses the concepts of both procedure and reactivity in such a way that middle school students can more easily learn how to program robots, something that is often difficult to attempt even for professional programmers.

Flavonoids contained in grapes are potent antioxidants that may protect against oxidative stress and reduce the risk of chronic diseases related with free radical damage. In this study we investigated the effect of daily grape juice supplementation on blood pressure (BP), plasma lipid profiles and the generation of free radicals in 67 healthy volunteers (29 smoker, 38 nonsmokers). The daily 480 ml of grape juice supplementation for 8 weeks resulted in a significant decrease in diastolic BP by 6.5％ in smokers and systolic and diastolic BP by 11.2 and 3.7％ in non-smokers. Plasma total cholesterol, HDL- and LDL-cholesterollevels in smokers and total cholesterol in non-smokers were significantly increased after the intervention. Plasma triglycerides and conjugated dienes were not affected by grape juice supplementation. Levels of free radical determined by reading the lucigenin-perborate ROS generating sources, decreased significantly by 18％ compared to the beginning of the study. The results indicated that the consumption of grape juice may reduce BP and free radical generation in smokers, which was possibly exerted by flavonoids. Our findings suggested that the grape juice has protective effect on chronic disease due to the overproduction of free radical in smokers.

This study investigated the effect of presenting modes of multiple analogies on middle school students' understanding of science concepts. A total of 122 7th-graders was randomly assigned to one of 4 groups. After reading one of 4 analogy-learning materials in different analogy presenting modes (the number of analogs, the number of mappings between analog and target, and the comparison of similarity between analogs). the students took a conception test. The results indicated that using analogs and mappings twice were not significant factors in recalling and applying science concepts. However, the comparison of similarity between analogs was found to be a significant factor in applying science concepts. Educational implications are discussed.

This paper presents experimental results which explore the capability of a CW laser speckle photography for tile measurement of in-plane displacement at high temperature. The serious restrictions on the application of the method seem to be the ambient air turbulence and the change of surface texture caused by the oxidation, as they tend to decorrelate the double exposured speckle patterns. In order to assess only the effect of air turbulence, a ceramics-coated stainless steel plate is heated in air and Ar-laser specklegrams are made with combination of temperature and lateral translation displacement. The slight reduction in visibility of Young's fringes is observed at $1000^{\circ}C$. The analyses of Young's fringes are carried out by a image processing system using a TV-camera and computers, and the result agrees well with the micrometer reading. Futhermore, uncoated stainless steel and Hastelloy X plates are tested and the effect of oxidation is also evaluated. The experimental results demonstrate that a CW laser speckle photography is applicable at temperatures up to $1000^{\circ}C$.
