The youth-pursing syndrome is especially amplified through a variety of media due to medical technology development, increases in social activities, and influence. This study discusses the relationship of youth-pursuing, media appearance information interest, and media contact responses focused middle-aged women. Data were collected from 245 females aged 40-65 in Seoul, Daejeon and Chungbuk area residents. The SPSS WIN 21.0 program analyzed the data by descriptive statistics, factor analysis, and regression analysis. Youth-pursuing derived social, psychological, and outward factors. Only an outward factor of these three dimensions influenced a significant media appearance information interest, and media contact response. The regression analysis results for chronological age and cognitive age, cognitive age influenced all variables significantly (three factors of youth-pursuing, media appearance information interest, and media contact response). But chronological age influenced significantly only the media appearance information interest. This study verified the relationship of youth-pursuing and media variables (media appearance information interest and media contact response).

In order to get the drive reliability and low Power-consumption characteristics, most of small form factor HDD has und the load/unload mechanism instead of CSS type. Compared with CSS mechanism, the load/unload system has little opportunity of head/media contact during the disk spin-up and down. However, the load/unload mechanism needs the precise integration technology with slider, suspension, ramp and load/unload velocity, and all of these component s should be designed simultaneously, not an individually. In this paper, we focus the design of the suspension stiffness using the specified ABS design. We use the CML software to calculate the load/unload dynamic and use the RSM(Response surface method) to get the optimal condition of the suspension stiffness.

Evaluation of an amplitude domain reflectometry (ADR) type soil moisture sensor as ThetaProbe ML2x using the response of frequency impedance was performed in a variety of soil porous media such as Jumunjin standard sand, weathered granite soil at Sangju area, and weathered gneiss soil at Jangsu area. The tested soils were classified with a dried condition and a wetted condition for comparing with soil volumetric water content under different installed depths of the measurement sensor. In the results the part of measurement rod including one signal rod and three shield rod 6cm in length was found to decrease the variation of measurement output voltage with insert 5cm over into the soil porous media. The measurement output voltage was verified to more stable output voltage under weathered granite soils and weathered gneiss soils contained the fine grain materials such as clay and silt minerals than the gradual grain material like as the standard sands. Therefore, measurement values by soil moisture sensor can be offered the more stable values when an contact volume between soil porous media and measurement sensor increase.

Non-Contact society has arrived due to social distinctions by COVID 19 pandemic. The arrival of the era of non-contact is having a profound impact on educational activities as well as on our social and economic lives. In response to the pandemic situation universities and all other educational institutions have implemented non-contact online classes. In particular arts physical educations and other practical classes are experiencing many difficulties due to the limited environment caused by social distancing from COVID 19 pandemic. Vocal classes are undergoing a transition mainly from 1:1 individual face-to-face lessons or group teaching methods to the non-contact era of online teaching or lesson methods. It is necessary to look at the direction of non-face-to-face practical classes in preparation for accelerated educational innovation. Edu-tech, which innovates technology in the wake of the age of non-contact after COVID 19 pandemic is expected to begin in earnest at school sites in Korea which have remained in the traditional way of education. The purpose of this study is to effectively non-contact vocal instructional methods by cogitating the current state of higher practical education and vocal classes in Korea. In addition, This study conducted two components of satisfied instructions such as 'Priorlearning of monitoring of recorded singing', and 'Immediate analyzing of various vocal contents and supplementary lessons of music theory' with a research on the peos and cons of non-face-to-face vocal class. Over a period of time, The effective non-contact of vocal instructional methods is in need to supplement non-face-to-face vocal class problems and further research and system construction with non-face-to-face vocal class's pros and cons to construct high-quality lecture contents is warranted.

Polydimethylsiloxane (PDMS) is one of the most widely adopted silicon-based organic polymeric elastomers. Elastomeric nanostructures are normally required to accomplish an explicit mechanical role and correspondingly their mechanical properties are crucial to affect device and material performance. Despite its wide application, the mechanical properties of PDMS are yet fully understood. In particular, the time dependent mechanical response of PDMS has not been fully elucidated. Here, utilizing state-of-the-art PeakForce Quantitative Nanomechanical Mapping (PFQNM) together with Force Volume (FV) and Fast Force Volume (FFV), the elastic moduli of PDMS samples were assessed in a time-dependent fashion. Specifically, the acquisition frequency was discretely changed four orders of magnitude from 0.1 Hz up to 2 kHz. Careful calibrations were done. Force data were fitted with a linearized DMT contact mechanics model considering surface adhesion force. Increased Young's modulus was discovered with increasing acquisition frequency. It was measured 878 ± 274 kPa at 0.1 Hz and increased to 4586 ± 758 kPa at 2 kHz. The robust local probing of mechanical measurement as well as unprecedented high-resolution topography imaging open new avenues for quantitative nanomechanical mapping of soft polymers, and can be extended to soft biological systems.

Recently, the tourism industry faced a crisis due to COVID-19. Smart tourism that combines information and communication technology (ICT) is rapidly growing to overcome the crisis in the tourism industry. In order to revitalize the tourism industry after COVID-19, such as non-face-to-face and non-contact, smart tourism incorporating information and communication technology (ICT) is actively encouraged and promoted. The purpose of this study is to empirically verify how perceived pleasure, perceived awakening, and perceived domination, which are three important variables of emotional response theory, affect the intention to continue use through perceived usefulness, expectation, and satisfaction. The survey was conducted for two weeks from November 1 to 15, 2020. A total of 175 surveys were collected during the period and used for analysis. As a result of the study, first, perceived pleasure did not significantly affect perceived usefulness, expectation, satisfaction, and intention to continue use. Second, perceived awakening had a significant effect on expectations, but did not significantly affect perceived usefulness, satisfaction, and continued use intention. Third, perceived domination had a significant effect on perceived usefulness, expectation, and continued use intention. However, it did not significantly affect satisfaction. Fourth, perceived usefulness did not significantly affect satisfaction. Fifth, expectations had a significant effect on perceived usefulness and satisfaction. Sixth, satisfaction had a significant effect on the intention to continue use. Through this, companies and developers that provide online review content for aviation and hotels should know what part of the content is actually focused on and provide it to customers. In addition, content should be provided in consideration of the emotional aspects that aviation and hotel online review users feel while watching videos.

Bakground: At our institution, We have controlled pain during vaginal delivery with epidural block since 1986. We designed a questionaire for parturients to analyze the degree of satisfaction of epidural block. Method: The self-questionaire were sent to parturients(N=200), who had epidural block to control labor pain during vaginal delivery. The questionaire covered topics dealing with motivation, fear, satisfaction and complications, of epidural block. Results: Motivation by an experienced person was 72.5%(145 parturients), fear of epidural block was 66%(132 parturients), and satisfactory response was 84%(168 parturients). Parturients who knew the role of anesthesiologist numbered 105(52.5%). Scarcely, 46 parturients displayed confidence for safety of fetus; 111 parturients experienced more than one complications. But special therapy for complications were not necessary. Conclusions: Publicity through mass-media and direct contact will improve the recognition and merit of epidural block by parturients as well as the role of the department of anesthesiology.
