This study introduces a high-fidelity and low-power strain visualization system along with a cloud-based data management approach for long-term structural health monitoring (SHM). The strain was visualized as a QR code on an electronic paper display. .The accuracy of the proposed system was validated with a reference strain measuring system (Xnode) in a lab-scale experiment. A cantilever beam mounted with a table was deflected with increasing load, and strain response was measured from both systems. Furthermore, an experiment at POSCO was conducted for the application of a multi-channel visualization system to structures.

From 2013 to 2015, the National Institute of Health, Pakistan, received 1,270 blood samples of suspected dengue cases reported from inpatient and outpatient departments of various hospitals in Khyber Pakhtunkhwa (KPK) province. In this study, we determined the circulating dengue virus (DENV) serotypes using real-time reverse transcriptase (RT)-PCR to understand the serotype-based epidemiology of DENV. All four serotypes (DENV-1 [6%], DENV-2 [33%], DENV-3 [47%], and DENV-4 [0.1%]) were found circulating during the study period. Our findings suggest the need for an active surveillance system coupled with the laboratory diagnosis, especially in the chronic endemic areas of the country. Public awareness programs are needed for effective control and prevention of outbreaks in the future.

In this paper, a generalization of the exponential integral is given. As a consequence, several inequalities involving the generalized function are derived. Among other analytical techniques, the procedure utilizes the Holder`s and Minkowski`s inequalities for integrals.

Background: Patients' demographics, presenting clinical and histopathological features for colo-rectal cancer (CRC) are important factors for patients' outcome and disease prognosis. This study aimed to describe the pattern of CRC in terms of patients' demographics, main presenting symptoms and histopathological features in Al Hassa region of Saudi Arabia. Subjects and Methods: A retrospective hospital records-based study which included reviewing of patients' records diagnosed with CRC at three general hospitals in Al Hassa region, Saudi Arabia. A compilation form was designed to collect information regarding socio-demographics, age at diagnosis; referral sites and the main presentations at CRC diagnosis. sites and the main presentations at CRC diagnosis. Histopathological reports were reviewed to delineate the main cytopathologic features, prominent cytological characteristics, the presence of predisposing pathology, and disease stage. Results: Of the 142 cases with CRC, 15.5% and 33.1% were affected before 40 and 50 years of age respectively. Emergency rooms were main referral sites for CRC cases (31.0%). Right colon was affected in 16.9% while left colonic lesions accounted for 62.7%. Intestinal obstruction was the main presentations (41.5%), and 26.1% presented with symptoms indicating distant metastastic lesions. Adenocarcinoma was the predominant pathological lesions (86.6%). Metastastic CRC was diagnosed in 62.7%. Duke's staging showed that 22.5% and 40.1% of lesions were classified into C and D categories respectively. Conclusion: Saudi patients with CRC present late with distant metastasis, and advanced disease stage. A sizeable proportion of patients developed the lesions at relatively young age. Screening recommendations should be enacted and revised in response to current change with younger age of affection.

Studies were conducted to determine the effects of temperature, solute potential and carbon source on the mycelial growth, sclerotia development, and apothecium production of an isolate of Sclerotinia sclerotiorum. Mycelial growth rate was greatest at 25oC on potato dextrose agar (PDA) medium amended with up to 2% NaCl (ψs ≤ 1.91 MPa) and thereafter, growth rate declined. The least number of sclerotia were produced at 20oC on both PDA and malt extract agar (MEA) amended with 8% NaCl (ψs=6.62 MPa). With increasing temperature and decreasing solute potential the number and size of sclerotia were significantly reduced. The combined effect of temperature, solute potential and carbon source on sclerotia production were highly significant and had an impact on the development of the rind layer cells of sclerotia. These cells lacked a transparent cell wall which was surrounded by a compact melanized layer, and some of these cells appeared to be devoid of cell contents or were totally vacuolated. The survival of the sclerotia with increase in salinity and temperature appeared to affect melanization and the nature of the rind cells. The observations of this study re-enforces the need for an integrated disease management to control S. sclerotiorum.
전위차법(EPDM)기반 스마트 센서를 이용한 강부재의 균열 모니터링

과거부터 EPDM을 이용한 강 구조물의 균열 모니터링에 관한 연구는 이뤄지고 있었으나 장기간적 구동, 데이터로의 접근성 등의 문제를 해결할 시스템은 부재하다. 균열은 콘크리트뿐 아니라 강부재의 수명 저하에도 큰 원인이 되는 요인이기 때문에 저전력으로 장기간 구동 가능한 스마트 센서를 이용해 균열의 모니터링부터 데이터로의 접근성을 향상시키는 시스템은 SOC 유지관리에 꼭 필요한 기술이다. 본 연구에서는 저가로 멀티채널 측정이 가능한 센서를 개발했으며, 센싱 데이터로의 접근성을 향상시키기 위해 EPD를 이용한 QR코드의 시각화 또는 AWS MQTT Broker를 이용한 서버 통신망 구축을 통한 균열 모니터링 실험을 수행한 결과를 소개한다. 본 기술이 현장에 적용되면 SOC의 유지관리가 보다 경제적이고 스마트하게 실시될 것으로 기대된다.
