The purpose of this research was to investigate the effects of skin pressure by wearing all-in-one on the rhythm of body temperature such as skin and rectal temperature which play a crucial role in the nocturnal rhythm. Five healthy female were participated in the study as subjects. The experimental clothing was an all-in-one, one of the foundation, which is worn for shaping the body. The total experimental periods were 5 days. On the 1st day, subjects did not wear the all-in-one (None), and they wore it for about 12 hours per day from 2nd to 5th day (Wearing1~4). Skin and rectal temperature were measured during the entire experimental days to figure out the rhythm of body temperature during sleep. When subjects wore the all-in-one, the gradients of the forearm and calf skin temperature at the sleep onset were significantly smaller than "None". It indicated that the rise of extremities' skin temperature was low on the "Wearing1~4". The decline of rectal temperature in "Wearing 1~4" was smaller than "None". Therefore, the skin pressure by all-in-one may cause the temperature of extremities' skin and rectum to change, resulting the fluctuation of the circadian rhythm, finally it could have effects on the rhythm of sleep.

With the development of digital technology, the size of the smart agriculture market at home and abroad is rapidly expanding. It is necessary to establish a foundation for sustainable precision agriculture in order to respond to the aging of rural areas and labor shortages. This study was conducted to establish an automated digital agricultural test bed for soybean production management using data suitable for agricultural environmental conditions in Korea and to demonstrate the field of leading complexes. In order to manage water smartly, we installed a subsurface drip irrigation system in the upland field and an underground water level control system in the paddy field. Based on data collected from sensors, water management was controlled by utilizing an integrated control system. Irrigation was carried out when the soil moisture was less than 20%. For effective water management, soil moisture was measured at the surface, 15cm, and 30cm depth. The main growth characteristics and yield, such as stem length, number of branches, and number of nodes of the main stem, were investigated during the main growth period. During the operation of the test bed, drought appeared during the early vegetative growth period and maturity period, but in the open field smart agriculture test bed, water was automatically supplied, reducing labor by 53% and increasing yield by 2%. A test bed was installed for each field digital farming element technology, and it is planned to verify it once more this year. In the future, we plan to expand the field digital farming technology developed for leading farmers to the field.

Purpose: Mobility impairment persons are all people who experience mobility difficulties in their daily lives, which makes up about 30% of the population in Seoul Metropolitan City; this number is expected to increase with population aging. As the number of mobility impairment persons in need of vision correction increases, it is necessary to create the Universal Design guidelines and to provide the foundation to access convenience facilities at the entrance of optical shops, a health and medical institution. Methods: Of the 2,282 optical shops located in Seoul, 252 optical shops were chosen for data collection of actual photos, from April 10, 2022 to September 4, 2022. Based on the photographs, the height difference between the entrance and the sidewalk, safety handles, and opening and closing methods of entrances were investigated, as these factors correspond to the accessibility and the mobility of the mobility impairment persons. Results: Of the 252 optical shops surveyed, 114 (45.2%) have resolved the problems of height difference through improving horizontal accessibility (61) or using ramps (53). 36 (14.3%) optical shops chose automatic doors for opening and closing methods of the entrance. Implications: The rate of installation of access convenience facilities for the entrance of optical shops is slightly lower than the rate of installation of ramps, surveyed by the Ministry of Health and Welfare. It is necessary to apply the Universal Design to access convenience facilities for the entrance of optical shops for not only the mobility impairment persons but all people, regardless of age or ability, to conveniently access healthcare services.

This study was conducted to investigate the anti-oxydant and anti-winkle efficacy as cosmetics ingredient of Lysimachia christinae Hance. Recently, the study of wrinkle improvement of natural products has received continuous interest. so we looked at relationship between reactive oxygen species (ROS) generation and pro-collagen synthesis and matrix metalloproteinases (MMPs) through this study. L. christinae Hance were extracted with 70% ethanol (LcHE) and distilled water (LcHW), respectively, and the experiment was conducted. LcHE had better ROS inhibition effect than LcHW and showed no toxicity up to 250 ㎍/mL concentration as a result of MTT assay in HaCaT cells, so we selected LcHE and conducted the wrinkle improvement material study. We confirmed that the synthesis of type-1 pro-collagen reduced by UVB is activated through pro-collagen synthesis assay. we confirmed that LcHE inhibited the increase in MMP-1 -3 -9 of MMPs induced by UVB in skin cells through western blot and we also performed real-time PCR to confirm the effect of the extract with dependence of concentration at mRNA levels. Therefore, it is expected that Lysimachia christinae Hance is used as a natural material for cosmetics that can effectively prevent wrinkles and skin aging by UVB.

In this paper, the behaviour of composite steel-CFRP members is studied experimentally and using FE-analysis. The use of advance composite materials in construction for repair and rehabilitation has become a frequent used method in the last decade. FRP composites have many advantages over the traditional technique of steel bonding for a number of reasons: 1. Composites add little or no additional weight to a building, eliminating the need for costly foundation strengthening. 2. FRP composites are very thin (1.2mm to 1.4mm). So there is no loss of floor space and negligible effect over the architectural aspect. 3. FRP composites do not corrode, this makes it long lasting. However, the method is yet to become a mainstream application due to a number of economical and design related issues. Brittle debonding failure, aging effect on bonding, broad based awareness and proper design guidelines are the main concern for future research works. This paper is focused on the ultimate load carrying capacity of the CFRP-strengthened beams and their effect on the deflection and failures modes by varying the amount of CFRP content.
