The purpose of this study was to assess the feasibility and the effects of near infrared lighted garments on thermo-physiological responses in human body. Seven healthy adult men were recruited for this study. All subjects were informed the contents and purpose of this study. The experiment was carried out in a climate chamber of $32^{\circ}C$, 60%RH with 'Rest', 'Exercise' and 'Recovery' period. The experimental garments consisted of briefs, undershirts(sleeveless), nightclothes, T-shirts, knee-trousers and socks. Subjects participated in two experiments, one was wearing near infrared lighted garments(NIR-O), the other was wearing regular garments(NIR-X). The order of experiment was randomized, and subjects wore experimental garments before 24 hours in order to benefit by near infrared light. Measurement items included rectal temperature ($T_{re}$), mean skin temperature ($\bar{T}_{sk}$), sweat rate, heart rate, oxygen uptake and subjective sensation. The results are as follows: As to the variation of rectal temperature and mean skin temperature, value of wearing NIR-X was higher than value of wearing NIR-O, indicating a significant level of difference (p<.001). Sweat rate under NIR-O and NIR-X condition were 575.35 g and 535.75 g, respectively. Heart rate value of NIR-X condition was higher than NIR-O. Oxygen uptake measured during experiment was the higher in NIR-X condition with significant difference (p<.001). In the subjective sensation, the value of NIR-O condition was higher than NIR-X condition without significantly difference.

In this paper, we propose the method that improve the performance of the Mowse. Mowse is the tool of the peptide mass fingerprinting that is used the identification of protein. In Mowse, frequency factor matrix is generated to regular interval for protein and peptide mass and the value of each elements is calculated to frequency of peptide. We propose new method for calculation of exact scoring value maintaining same size of matrix. The proposed method is that decide interval of matrix considering distribution of protein database. That is, interval of matrix is decided to small in many value of protein mass and is decided to large in few value of protein mass. We present the performance result both Mowse scoring method and the proposed scoring method.

The purpose of this study was to present the reference value of the intracranial translucency(IT) of the fetus using the mid sagittal plane of the post brain in the early pregnancy ultrasound screening test and to find the clinical significance. From August 2018 to February 2020, the IT of 1529 singleton fetus whose crown lump length were 40.6 mm to 78.3 mm in length among the mothers undergoing regular checkups at Hospital I were measured and analyzed retrospectively. As the crown lump length increased, the IT showed a 54.3% explanatory power and tended to increase(p<0.001). In addition, through frequency analysis, the standard value for the percentile of the IT by gestational weeks was calculated. As a result, it was possible to establish a standard value for Koreans with an IT, and it will be usefully applied as an auxiliary screening test for spina bifida in the evaluation of fetal post brain in early pregnancy.

In today's world, we find ourselves facing energy crises due to factors such as war and climate crises. To prepare for these energy crises, many researchers continue to study systems related to energy monitoring and conservation, such as energy management systems, energy monitoring, and energy conservation. In line with these efforts, nations are making it mandatory for energy-consuming facilities to implement these systems. However, these facilities, limited by space and energy constraints, are exploring ways to improve. This research explores the operation of a data collection system using low-performance embedded devices. In this context, it proves that an optimized version of RocksDB, a Key-Value store, outperforms traditional databases when it comes to time-series data. Furthermore, a comprehensive database evaluation tool was employed to assess various databases, including optimized RocksDB and regular RocksDB. In addition, heterogeneous databases and evaluations are conducted using a UD Benchmark tool to evaluate them. As a result, we were able to see that on devices with low performance, the time required was up to 11 times shorter than that of other databases.

Fashion is traditionally perceived as a non-art in art philosophy; however, it is now being evaluated as art through the process of recognizing its cultural value and position. This study investigated the expanded concept of contemporary fashion in the same context of the expanded concept of contemporary art to present the possibility of fashion as art. This study enhances the artistic and cultural value, as well as the social function and position, of fashion by granting it the same status as art according to the concept of expanded contemporary art. For the research method, a literature review and a case analysis were conducted through specialty publications related to art history, aesthetics, and fashion in addition to regular publications, websites specializing in fashion, art museums and fashion style websites. The expanded aesthetic concept of contemporary art has embraced challenges to ideal beauty, production methods through interactivity, and expansion of art expression through mass media and industrial products. In the same context, the expanded aesthetic concept of contemporary fashion has established challenges to conventional beauty, the expansion of production methods, and the expansion and transfiguration of materials.

In general, the study of a high-rise building's behaviour when subjected to a horizontal load (wind or earthquake) is carried out through numerical modelling with finite elements method. This paper proposes a new, original approach based on the use of a multi-beams model. By redistributing bending and axial stiffness of horizontal elements (beams and slabs) along vertical elements, it becomes possible to produce a system of differential equations able to represent the structural behaviour of the whole building. In this paper this approach is applied to the study of bending behaviour in a 37-storey building (Torre Pontina, Latina, Italy) with a regular reinforced concrete structure. The load considered is the wind, estimated in accordance with Italian national technical rules and regulations. To simplify the explanation of the approach, the wind load was considered uniform on the height of building with a value equal to the average value of the wind load distribution. The system of differential equations' is assessed numerically, using Matlab, and compared with the obtainable solution from a finite elements model along with the obtainable solutions via classical Euler-Bernoulli beam theory. The comparison carried out demonstrates, in the case study examined, an excellent approximation of structural behaviour.

This paper compares and analyzes Fusarium wilt of radish by using an unmanned aerial vehicle(UAV) with the NDVI-7 camera. The UAV have taken near-infrared images of the Radish field in Gangwon area, which is affected by Fusarium wilt. Based on those images, we analyzed NDVI(Normalized difference vegetation index) and compared conditions of radish by using the Blue value among Regular Vegetation Index in NDVI. First, the radish field is divided into three fields for radish, soil and vinyl. Each field has separate Blue values that are radish 0.4890, soil 0.2959, vinyl -0.0605 respectively. Second, radish condition levels are divided into four stages which are normal, early, middle, and late stage of Fusarium wilt. The average values of each stage are normal 0.5165(100%), early 0.4565(88%), middle 0.3444(66%), and late 0.1772(34%) respectively. This result shows that this NDVI value is validated by measuring conditions of Radish and soil.

The high-solid coatings were prepared by blending the synthesized acrylic resin in the previous paper and hexamethylene diisocyanate-trimer and curing it at room temperature. The characterization of the films of the prepared coatings was performed. The impact resistance, $60^{\circ}C$ specular gloss, cross-hatch adhension, and heat resistance of the films proved to be good, and the pencil hardness and drying time proved to be slightly poor. Especially, there was a remarkable improvement in the heat resistance. This improvement may stem from the regular arrangement of ethyl groups introduced into the acrylic resin. From a viscoelastic measurement using a rigid-body pendulum, curing was accelerated with the $T_g$ value. With the increase in $T_g$, log damp value was lowered and dynamic viscoelasic $T_g$ of a cured film was increased.
