Existing flapping MAV which is driven by motors or the other materials, has various defects. For the settlement of the issue, flapping MAV wing actuator is developed by using ADE(Acrylic Dielectric Elastomer). In comparison with existing materials which drive flapping wing, ADE has advantages of light weight as well as sufficient force. In order that correct lift farce occurs at this actuator, it must require to control to approach given reference. So it is controlled to approach given displacement by using fuzzy algorithm and is verified through simulation.

SMP 클러스터가 고성능 계산을 위한 플랫폼으로 등장함에 따라, 이 시스템을 활용하기 위한 프로그래밍 환경에 대한 관심이 증가하고 있다. 이 논문에서 우리는 ParADE라고 부르는 쉽고, 이식성이 높으며. 고성능의 프로그래밍이 가능한 새로운 프로그래밍 환경을 소개한다. ParADE는 OpenMP 프로그래밍 환경으로 HLRC 변종 프로토콜을 구현한 다중 쓰레드 DSM 시스템을 기반으로 하고 있다. 특별히. 이 논문에서는 성능 개선을 위한 OpenMP 변환기의 역할에 중점을 둔다. OpenMP 변화기는 OpenMP 프로그램 모델과 실행 시스템의 수행 모델 사이에서 가교 역할을 한다. 특히, OpenMP 변환기는 동기화 디렉티브를 변환하고 임계 영역에 있는 작은 변수의 메모리 일관성을 유지하기 위해 집합 통신 함수를 활용한다. 동기화 디렉티브 성능 측정을 위한 마이크로벤치마크 프로그램을 통한 실험에서 ParADE 시스템은 기존의 DSM 시스템에 비해 우수한 성능을 보였다.

Bacterial transport models were evaluated in this study to determine the suitable model at describing bacterial transport in saturated column experiments. Four models used in the evaluation were: advective-dispersive equation (ADE) + equilibrium sorption/retardation (ER) + kinetic reversible sorption (KR) (Model I), ADE + two-site sorption (Model 2), ADE + ER + kinetic irreversible sorption (KI) (Model 3), ADE + KR + KI (Model 4). Firstly, analyses were performed with the first experimental data, showing that Model 4 is appropriate for describing bacterial transport. Even if Model 1 and 2 fit well to the observed data, they have a defect of not including the irreversible sorption, which is directly related to mass loss of bacteria. Model 3 can not properly describe the tailing observed in the data. However, further analysis with the second data indicates that Model 4 can not describe retardation of bacteria, even if the sorption-related parameters are varied. Therefore, Model 4 is modified by incorporating retardation factor into the model, resulting in the improved fitting to the data. It indicates that the transport model, into which retardation, kinetic reversible sorption, and kinetic irreversible sorption are incorporated, is suitable at describing bacterial transport in saturated column experiments. It is expected that the selected transport model could be applied to properly analyze the bacterial transport in saturated porous media.

Objectives: This study analyzed the relationship between parental body mass index (BMI; BMI_p) and hypertension in their adolescent offspring (HTN_a), focusing on the mediating effect of adolescents' BMI (BMI_a). Methods: Utilizing data from the Korea National Health and Nutrition Examination Survey, including participants aged 12-18, we conducted a mediation analysis while controlling for confounding factors such as age, sex, physical activity, dietary habits, household income quartile, and parents' alcohol and smoking habits. Results: The study included a total of 5731 participants, of whom 3381 and 5455 participants had data on fathers' and mothers' BMI, respectively. For adolescent systolic blood pressure (SBP_a), the father's BMI (BMI_f) had a significant total effect (β, 0.23; 95% confidence interval [CI], 0.12 to 0.34) and average controlled mediated effect (ACME) (β, 0.27; 95% CI, 0.23 to 0.32), but the average direct effect (ADE) was not significant. The mother's BMI (BMI_m) had a significant total effect (β, 0.17; 95% CI, 0.09 to 0.25), ACME (β, 0.25; 95% CI, 0.22 to 0.28) and ADE (β, -0.08; 95% CI, -0.16 to 0.00). For adolescent diastolic blood pressure, both BMI_f and BMI_m had significant ACMEs (β, 0.10; 95% CI, 0.08 to 0.12 and β, 0.09; 95% CI, 0.07 to 0.12, respectively), BMI_m had a significant ADE (β, -0.09; 95% CI, -0.16 to -0.02) but BMI_f had an insignificant ADE and total effect. Conclusions: The study found that parental BMI had a significant effect on SBP_a, mediated through BMI_a. Therefore, a high BMI in parents could be a risk factor, mediated through BMI_a, for systolic hypertension in adolescents, necessitating appropriate management.

Educational environments in rural areas have been slowly deteriorating due to the popular flow of people moving into the city from the countryside. It has been concluded that superannuated educational facilities have a negative influence towards students. This research has been conducted in order to give better mental or psychological influence to those around and comfort and relaxation to the students themselves through developing new ways to renovate the $fa\c{c}ade$ of the run down educational facility. This research develops several structural and ecological (environmental friendly) elements which are used as several segmental elements of the new $fa\c{c}ade$ design for the degraded educational facilities. A combination of these design elements can develop many viable alternatives of a new $fa\c{c}ade$ renovation. These new renovations can help students to maintain their educational and social lives in a safer and more ecological environment.

최근 소셜미디어 리뷰 데이터를 활용한 약물 이상 반응 탐지 연구가 활발히 진행되고 있지만, 약물을 복용하기 전 증상과 약물 이상 반응을 구분하지 못한다는 한계가 있다. 본 논문에서는 약물 이상 반응 탐지에서 약물 복용 전의 증상을 구분할 수 있는 Filtering Clinical BERT(FC-BERT) 모델을 제안하였다. FC-BERT 는 약물 복용 전 증상과 다른 약물에 대한 부작용 표현을 제거하기 위해 약물명이 나오기 전 모든 문장을 제거하는 필터링과 약물-부작용 쌍을 추출하는 모델을 사용했다. 성능 평가 실험을 위해 문장에 대한 ADE(Adverse Drug Event) 여부가 들어있는 ADE Corpus V2 데이터를 활용하였고 SPARK NLP 라이브러리에서 제공하는 ADE Pipeline 모델과 비교하여 성능 평가를 실시하였다. 실험 결과 필터링을 활용한 FC-BERT 모델이 기존 모델보다 정확도, 평균 정밀도, 평균 재현율, 평균 F1-score 가 모두 높은 결과를 보여주었다. 본 논문에서 제시한 모델은 기존 연구의 한계점을 보완하여 보다 정확한 약물 부작용 시그널을 탐지하는데 기여할 수 있을 것이다.

This study was designed to investigate the amount of free sugar according to each beverage category in coffee and beverage stores. The groups were categorized as 15 groups based on the kind of beverage material. The beverage groups contributing to total sugar per 100 mL were milk + syrup or powder, hot (12.9 g), ade (12.6 g), milk + syrup or powder + crushed ice (11.9 g), and espresso shot + milk + syrup + crushed ice (11.4 g). The beverage groups contributing to free sugar per 100 mL were ade (12.6 g), milk + syrup or powder + crushed ice (10.8 g), espresso shot + milk + syrup + crushed ice (10.3 g), and milk + syrup or powder, hot (9.7 g). The beverage groups contributing to total sugar (energy) per portion size were milk + syrup or powder + crushed ice 56.6 g (332.3 kcal), espresso shot + milk + syrup + crushed ice 49.3 g (333.4 kcal), milk + syrup or powder, hot 46.3 g (372.1 kcal), and milk + syrup or powder, ice 38.1 g (325.9 kcal). The beverage groups contributing to free sugar per portion size were milk + syrup or powder + crushed ice 51.2 g, espresso shot + milk + syrup + crushed ice 44.9 g, ade 37.1 g, milk + syrup or powder, hot 34.6 g, and milk + syrup or powder, ice 30.1 g. The percent of average free sugar per portion size of the WHO recommendation (free sugars <10% of total energy; <50 g/2,000 kcal) was milk + syrup or powder + crushed ice 102.4%, espresso shot + milk + syrup + crushed ice 89.8%, ade 74.1%, and milk + syrup or powder, hot 69.2%. The proportion of beverage in excess of WHO recommendation per portion size was 14.6% in espresso shot + milk + syrup + crushed ice, 22.7% in ade, and 10.9% in milk + syrup or powder, hot. Therefore, in coffee and beverage stores, menu development with reduced sugar content is needed, and nutrition information should be provided through sugar nutrition labeling.
