Most users refer to existing online reviews to see if other users were previously satisfied or not about the products (or foods) they want to buy. Meanwhile, some users do not want to write fruitful, realistic reviews because it is annoying and bothering. To minimize users’ writing costs, we are interested in implementing an automatic review generator to create a complete review with only scores and a few seed keywords by enabling intensity control tailored to the user’s needs. To this end, we propose an intensity controlled review data construction method for online review. Moreover, we employ GPT-2 and BART models popular for text generation tasks for the review generation experiments. Our automatic and manual evaluations for randomly sampled generation results prove the quality of our constructed dataset.

A 1.8 μm thick polycrystalline diamond (PCD) thin film layer is prepared on a Si(100) substrate using hot-filament chemical vapor deposition. Thereafter, its thermal conductivity is measured using the conventional laser flash analysis (LFA) method, a LaserPIT-M2 instrument, and the newly proposed light source thermal analysis (LSTA) method. The LSTA method measures the thermal conductivity of the prepared PCD thin film layer using an ultraviolet (UV) lamp with a wavelength of 395 nm as the heat source and a thermocouple installed at a specific distance. In addition, the microstructure and quality of the prepared PCD thin films are evaluated using an optical microscope, a field emission scanning electron microscope, and a micro-Raman spectroscope. The LFA, LaserPIT-M2, and LSTA determine the thermal conductivities of the PCD thin films, which are 1.7, 1430, and 213.43 W/(m·K), respectively, indicating that the LFA method and LaserPIT-M2 are prone to errors. Considering the grain size of PCD, we conclude that the LSTA method is the most reliable one for determining the thermal conductivity of the fabricated PCD thin film layers. Therefore, the proposed LSTA method presents significant potential for the accurate and reliable measurement of the thermal conductivity of PCD thin films.

Human health status can be mainly determined from the available vital signals parameters that can be acquired directly from the body. Sensing vital signs (VSs) can be categorized into: contact-based techniques and contact-less based techniques. This paper presents a concise taxonomy on state of the art VSs detection methods. It also highlights its classifications, comparisons and challenges, with a view to providing a one stop material towards understanding techniques for detecting VSs.
여자청소년의 양성평등의식과 신체활동: 남녀 청소년 비교를 통해

연구 목적 : 남녀 청소년의 신체활동 관련 경험 비교를 통해 여자청소년의 양성평등의식과 신체활동의 연관성을 파악하고자 하였다. 연구 방법 : 전국 청소년 1,500명을 대상으로 ‘청소년 성평등인식과 신체활동 경험조사(2019)’를 실시하여, 남녀 청소년의 양성평등의식, 신체활동 실천율 및 관련 요인을 비교하였다. 또한 양성평등의식과 신체활동 실천의 연관성을 파악하고자 다중로지스틱회귀분석을 실시하였다. 연구 결과 : 여자청소년이 남자청소년보다 양성평등의식이 더 높았고, 신체활동 실천율은 더 낮았다. 여자청소년은 연령이 낮을 수록, 어머니의 신체활동 지지가 높을수록 신체활동 실천율이 높았지만, 양성평등의식이 높을수록 주 3일 이상 격렬한 신체활동 실천은 더 낮은 것으로 나타났다. 반면, 남자청소년은 양성평등의식과 신체활동 실천 간에 통계적으로 유의한 연관성을 보이지 않았고, 여자청소년과 동일하게 남자청소년도 연령이 낮을수록 신체활동 실천율이 더 높았다. 결론 : 이 연구에서는 여자청소년의 연령과 어머니의 신체활동 지지가 신체활동과 연관성이 있는 요인으로 나타났다. 여자청소년의 양성평등의식은 높았지만, 양성평등의식과 신체활동 실천 간에는 역 상관관계가 나타났다. 향후 여자청소년의 신체활동 실천에 영향을 줄 수 있는 다양한 요인을 고려한 심층적인 연구가 필요하다. Purpose : This study examined the association between egalitarian gender norms and physical activity among adolescent girls in South Korea through comparison with adolescent boys. Methods : A nationwide survey of 1,500 Korean adolescents was analyzed. We compared egalitarian gender norms, physical activity and socio-demographic variables related with physical activity of adolescent girls and boys. To investigate the association between egalitarian gender norms and physical activity, multiple logistic regression models were used. Results : Adolescent girls had a higher awareness of egalitarian gender norms than boys, however the prevalence of physical activity was lower than boys. Younger girls or girls whose mother support their physical activity had a higher likelihood of physical activity. Adolescent girls who had higher awareness of egalitarian gender norms had a lower likelihood of physical activity. In contrast there was no statistically significant association between egalitarian gender norms and physical activity in adolescent boys. Conclusion : This finding shows that age and mother’s support for physical activity were associated with physical activity of adolescent girls. Girls had a higher awareness of gender equality but there was an inverse association between awareness of gender equality and physical activity. In the future, In-depth research is needed considering various factors that could affect physical activity of adolescents.
