In our previous study, a wire-plate type electrostatic precipitator (ESP) was developed to collect bioaerosols of 100 nm size. In the study, various flow rates (40 ~ 100 L/min) and applied voltages (3 ~ 10 kV) were tested for experiment. In this study, numerical analysis was performed for the ESP of the previous study with the same flow rates and applied voltages, but with varying the size of bioaerosols to 0.04 ~ 2.5 ㎛. Overall, the numerical analysis results well predicted the experimental data. Bioaerosols of 0.1 ~ 0.5 ㎛ showed the minimum collection efficiency for all conditions because of low charge number. The effect of the ionic wind generated by the corona discharge was calculated. However, the ionic wind did not affect much the collection efficiency. The aerosol collection in the ESP of this study was due to the electrostatic force generated by particle charge in the electric field. This numerical study on the ESP can be used for the design and optimization of higher flow rate (> 100 L/min) ESP.

Recently, United States Geological Survey (USGS) distributed Landsat 8 Collection 2 Level 2 Science Product (L2SP). This paper aims to derive land surface temperature from L2SP and to validate it. Validation is made by comparing the land surface temperature with the one calculated from Landsat 8 Collection 1 Level 1 Terrain Precision (L1TP) and the one from Automated Synoptic Observing System (ASOS). L2SP is calculated from Landsat 8 Collection 2 Level 1 data and it provides land surface temperature to users without processing surface reflectance data. Landsat 8 data from 2018 to 2020 is collected and ground sensor data from eight sites of ASOS are used to evaluate L2SP land surface temperature data. To compare ground sensor data with remotely sensed data, 3×3 grid area data near ASOS station is used. As a result of analysis with ASOS data, L2SP and L1TP land surface temperature shows Pearson correlation coefficient of 0.971 and 0.964, respectively. RMSE (Root Mean Square Error) of two results with ASOS data is 4.029℃, 5.247℃ respectively. This result suggests that L2SP data is more adequate to acquire land surface temperature than L1TP. If seasonal difference and geometric features such as slope are considered, the result would improve.

In a situation with reducing numbers of students and local universities in crisis, this study aims to analyze collection and loan usage data in small-sized university libraries and present evidence for guiding their collection development policy. The data was collected from Rinfo from 2010 to 2022 regarding the numbers of enrolled students, collected books, book loans, and electronic resources and compared the average values of entire 4-year university libraries to those of small-sized ones by year and region. Results show that while the numbers of enrolled students and book loans have decreased in both of groups, the number of collected books has increased 30% more in small groups and the amount of electronic resource use has increased enormously as well. Correlation analysis presents that both of groups have the consistent result. It is suggested that small-sized university libraries should highly increase their budget ratio to electronic resources for collection development and build a consortium by university's speciality for mutual use of electronic resources.

Jewelry has recognized as a part of independent formative arts of fashion with the change modern man's cognition for the fashion. It is a great important section to express fashion image. So, many corporations design and develop the jewelry by themselves to maxmize their fashion image. Among the so many kinds of jewelry, especially the necklace is located beneath the face and linked as a part of fashion, so it frequently has showed in Fashion Collection. Like this Fashion and jewelry enact each other and share their esthetic features but, it is insufficient the study of fashion linked with the jewelry. In this study, we defined the words which is using confusedly according to jewelry forms what researched by others. In addition, we tend to study the effect of that the form, hue and character of materials of necklace that is expressed in fashion collection influence fashion image. The method of this study is comprised with precedent studies and analysis of necklace photos in fashion collection. For the analysis of data, we implement content analysis and statistical analysis using SPAW Statistics 18(frequency analysis, percentage, cross-tabulations, $X^2$-test). Because the hue and the form of necklace take a great role to make fashion image with the sense of its eyesight, its effective coordination go up the delicate feelings with the form, hue and quality of the fashion. Especially, the hue is the essential element of formative characteristics to express visual image. The necklace had coordinated more frequently in S/S than F/W, it means that more light and simple fashion let ornamental beauty could express by the necklace. So, it is very effective things that we predict the trend of fashion, then, coordinate with well-matched necklace.

Recently, wearable computers equipped with various biosensors such as smart watches, smart bands, and smart patches that support daily health management of users as well as patients have been released. Users of wearable computers such as smart watches face various difficulties in performing biometric information processes such as data sensing, collection, transmission, real-time analysis, and feedback in a weak wireless and mobile biometric information service environment. In particular, the biometric information collection interface is an important basic process that determines the quality and performance of the entire biometric information service. So far, research has focused on sensing hardware and logic. This study intensively considers the interface method for effectively sensing and collecting raw biometric information. In particular, the process of collecting biometric information is designed and analyzed from the perspective of periodicity. Therefore, we propose an efficient and stable periodic collection method.
