Abstract	Agricultural operations and processes generate copious quantities of particulate matter (PM) both directly and indirectly through emissions of PM precursor gases with dire consequences for human health, environment and climate. PM emissions from agricultural activities are projected to continually rise in the light of soaring food demand driven by a ballooning global population, and thus, plausible measures are needed to combat them. Recently, interest in using biochar to attenuate PM emissions of agricultural origin, especially the secondary PM precursors, has gained traction and this review study is purposed to examine the capacity of the technology to curb the agricultural-related PM emissions basing on observations made in the previously concluded studies. The study gives a brief overview of the effects of PM and delineates its weighty agricultural sources plus detailing whether and how the pyrolysis technology and biochar as its product can help to alleviate the emissions. Additional discussions address the looming dilemma of biochar applications becoming a PM emission problem and the techniques that should be applied to ensure its sustainable usage. It is overwhelmingly clear from the studies reviewed that pyrolysis and resultant biochar have an enormous potential to attenuate PM from agriculture if adequately utilised.

Abstract	Objective: It is unclear whether photodocumentation is associated with colorectal neoplasm (CRN) detection at colonoscopy, despite its ability to take more images with the development of affordable digital imaging systems. This study aimed to investigate whether photodocumentation-related factors could affect the detection rate of CRNs in healthy subjects. Patients and methods: A total of 2,637 subjects undergoing screening colonoscopy in routine health check-ups at CHA Bundang Medical from January to September 2016 were enrolled in this study. Only the endoscopic image data for observation purposes during colonoscopy withdrawal was used in this analysis. The number of observation images, observation time and the speed of photodocumentation (SPD) defined as the number of observation images per minute were used as quantity measures of photodocumentation. The presence of documented anatomical landmarks such as appendix orifice (AO), ileocecal valve (ICV), anorectal junction was used as quality measures of photodocumentation. Results: Among subject-related factors, the independent factors for CRN detection in the multivariate analysis were age, male sex, waist circumference, and family history of colorectal cancer. In photo-documentation-related factors, SPD [Odds ratio (OR) 0.800; 95% confidence interval (CI), 0.740 to 0.864], observation time over 6 min (OR 1.671; 95% CI, 1.145 to 2.439), clear documentation of appendix orifice (AO) (OR 5.976; 95% CI, 4.548 to 7.852) and ileocecal valve (ICV) (OR 3.826; 95% CI, 2.985 to 4.904), and endoscopists (p < 0.001) were independently significant factors. However, the number of observation images was not associated with the detection of CRNs. Conclusions: Lower SPD and clear documentation of cecal landmarks might be associated with an increased detection rate of CRNs.

Abstract	OBJECTIVE: The aim of this study was to determine how gait speed and frontal lobe functionsin community-dwelling older adults in Korea. DESIGN: This was a cross-sectional study. SETTING: The study used data from the Korean Frailty and Aging Cohort Survey (KFACS), a multi-center longitudinal study addressing 10 centers across urban, rural, and suburban communities in Korea, between 2016 and 2017. PARTICIPANTS: A total of 1552 older adults who underwent both gait speed tests and cognitive functions tests during the investigation of the KFACS. MEASUREMENTS: Gait speed was assessed by asking participants to walk from a starting point to a point 4 meters away at a normal gait. Cognitive functions were evaluated using various standardized cognitive functions tests. RESULTS: Gait speed was slower when participants were older or less educated The percentage of women, higher BMI, people with lower incomes, singles, smokers, and drinkers was high in the slower gait group. Also, all cognitive function scores were low and depression score was high in the group with slower walking speed. The slower walking speed showed low physical activity score and high prevalence of hypertension, osteoarthritis and osteoporosis. Among the seven cognitive functions (MMSE, memory, TMT, Recall, Recognition, digit span, and Fab), only TMT showed no significant difference between different gait speed groups. The other six cognitive functions showed higher results in the fastest gait speed group (T3), Participants in middle gait speed group (T2) also showed higher results in five of the seven cognitive function scores as well (Memory, Recall, Recognition, digit span, and Fab). CONCLUSION: In this study, we found correlation between the slower gait speeds and the decrease in cognitive function, and especially the frontal lobe dysfunction was most prominent of all cognitive dysfunctions.

Abstract	Neurosurgery had been considered nearly impossible due to its technical difficulty and the danger to its special target organ, but with endoscopic methods, many such surgeries can be made safely through the nose. Endoscopic neurosurgery is limited by available instruments, however, and there remain some areas of the human body inaccessible to standard surgical tools. To overcome some of these limitations, in this study we developed a simple mechanism that could form a high curvature in a narrow space. The end product is a finger-like mechanism consisting of five body parts and four joints. All body parts are connected in series, having a total length of 20mm and a diameter of φ4mm. A four-bar linkage internally connects the body parts and joints, and a nitinol backbone was used to improve repeatability. The first joint is driven by a rod or wire, and the shape of the mechanism is determined by rotating the first joint, because the position of each joint depends on the position of the joint before it. The study verified that an image sensor in the end of the finger-like mechanism has a wider range of view, 210 degrees than a conventional endoscope of 100 degrees. Finally, skull model simulation suggests that this device could be used in real neurosurgical applications.

Abstract	Effect of the columnar grain boundaries on the perpendicular magnetic domain structure of epitaxial L10 FePt (001) thin film has been studied using electron holography. The analysis of stray fields shows that both the continuous and columnar epitaxial films of L10 FePt (001) consist of perpendicular magnetic domain walls. In the columnar epitaxial film, however, the perpendicular domain walls tend to be confined to columnar grain boundaries, because columnar boundaries act as pinning sites for the domain walls. The domain wall pinning by columnar grain boundaries leads to a significant hysteresis effect in the perpendicular magnetization of L10 FePt epitaxial films.

Abstract	Background: Posterior labral tear is frequently encountered in acetabular fractures with posterior wall component (AFPWC). However, there has been very little information in the literature on the type and management of traumatic labral tears in AFPWC. Hypothesis: Traumatic labral tear is a constant intracapsular injury in AFPWC and can be repaired using adequate methods according to its type and size. Materials and methods: A retrospective study of 14 patients (mean age 38 years [16-58]) who underwent open surgery for AFPWC was conducted using prospectively collected data. The types of posterior labral tear were investigated at intraoperative examination through the ruptured joint capsule or its extension, and were concomitantly managed. Surgical outcomes were clinically assessed using Merle d'Aubigné (PMA) score and Visual Analog Scale (VAS), and radiologically evaluated at final follow-up. Results: Posterior labral tears were present in all 14 patients. The types of labral tear were osseous avulsion and posterior root avulsion tear (n=9), longitudinal peripheral tear and posterior root avulsion tear (n=2), longitudinal peripheral tear (n=2), and osseous avulsion tear (n=1). All unstable labra in 12 patients (86%) were repaired. All avulsion tears of the posterior root were repaired using a suture anchor, longitudinal peripheral tears using suture fixation or/and suture anchors, and osseous avulsion tears using a spring plate. The mean PMA score and VAS were 16.4 (14-18) and 1.7 (0-3) at final follow-up, respectively. The radiologic grades at last follow-up were good or excellent in all patients. Discussion: All AFPWC in this study consistently revealed posterior labral tear. Posterior root avulsion tears accompanied with osseous avulsion was the most common type. Torn labra should be repaired as much as possible if unstable, considering the important functions of a normal labrum; fixation using a suture anchor may be useful for an avulsion tear of the posterior root. Level of evidence: Level IV, therapeutic case series.
