Authors: Handawati Rayuna 
Published: February 2020

Mental map sebagai gambaran tentang suatu wilayah dan lingkungannya, yang dikembangkan oleh individu atas dasar pengalaman sehari-hari dari berbagai sumber, antara lain dapat diperoleh melalui pembelajaran di sekolah dari guru dan media. Alat ukur keakuratan mental map seseorang terhadap suatu wilayah adalah mengkonfirmasi atau menerjemahkan dalam peta kartografis. Namun bersama peta kartografis, spektrum mental map peserta didik dapat dikembangkan tidak hanya berupa pengetahuan dan persepsi tentang lokasi geografis dari suatu obyek di permukaan bumi, peserta didik juga dapat melihat hubungan antar fenomena di permukaan bumi, pola, persamaan dan perbedaan hingga interdependensi suatu tempat dengan menerapkan prinsip dan pendekatan geografi. Mental map yang baik dan berkembang akan berguna bagi peserta didik dalam membuat keputusan untuk kepentingan pribadi hingga memberikan solusi kepada masyarakat. Guru berperan mendesain pembelajaran yang dimulai dari perencanaan, pelaksanaan dan evaluasi yang mengembangkan mental map. Setiap pokok bahasan geografi pada mata pelajaran geografi dijelaskan dengan sudut pandang geografi dalam skala lokal, regional dan global. Setiap pokok bahasan geografi di sekolah juga harus menerapkan prinsip maupun pendekatan geografi untuk memaksimalkan mental map peserta didik terhadap lingkungan tempat tinggalnya, negaranya dan internasional sesuai tujuan pembelajaran geografi di sekolah.
<p>Drawing the Line: The Challenges of Dysgraphia in Introductory Graphics
Communication Courses</p>
Authors: Kelly Daniel P. , Kelly Deidre L. 
Published: February 2020

Drawing and sketching require the close interaction and coordination of
psychomotor and biomechanical processes with developmental, learning, and maturational
processes to perform the complex and fine motor behaviors of these activities.
Dysgraphia is a learning disability that directly impacts a student’s ability to perform
these tasks proficiently, if at all. Although dysgraphia is literally interpreted as
“bad writing,” it also affects a person’s ability to visualize and draw lines and
shapes. STEM subject matter and activities often involve drawing and sketching, and this
ability to transfer mental imagery to paper and viceversa is one predictor of STEM
education and career success. Given this, there may exist a population of students who
are being overlooked and would benefit from a better understanding of the condition by
educators and potential interventions that can be researched to engage these students
within STEM disciplines. This paper will explore this learning disability as is
exists in STEM education through a narrative case study involving a student currently
enrolled in an engineering program. This case study is designed to understand the
condition of dysgraphia and the barriers to STEM education as perceived and experienced
by a student successfully mitigating these barriers through assistive technologies,
self-advocacy, and teacher awareness. This paper is meant to raise awareness of the
condition in our field and serve as a starting point in the literature where this topic
currently represents a dearth of the academic discourse surrounding special education in
STEM.

<p>Strawberries (Fragaria sp.) are mostly grown in the mountainy areas in Indonesia and need a long transportation to get to the consumers. Long transportation will cause more than 50% damage to strawberries due to decay. Handling procedures need to be good and proper from farmer to the consumer or processor customer so that fruit reach destination in expected condition. Handling was done during pre-harvest and postharvest so that the quality of fresh strawberry fruit can be preserved. The technology for handling strawberry fruits that already exists includes: pre-harvest by spraying with antimicrobial agent, postharvest include for collecting, sorting and grading, washing, dipping with calcium chloride or naphtalene acetic acid, waxing, fumigation with nitric oxide, coating with chitosan or aloe vera gel combined with glycerol, irradiation, packaging, storage and transportation. The recommended storage temperature for strawberries is at 4oC, it can extend the shelf life of strawberries up to 1011 days with the best chemical characteristics. Implementing of SNI to strawberries in Indonesia to increase product competitiveness and increase added value still needs intensive efforts. 1.The classification and quality standards of strawberries can refer to the SNI No. 8026, 2014 and the Commission Implementing Regulation (2011).</p><p>Keywords: Strawberry, preharvest, postharvest, fresh handling, quality</p><p> </p><p><strong>Abstrak</strong></p><p>Di Indonesia, stroberi (Fragaria sp.) umumnya tumbuh di daerah pegunungan sehingga memiliki risiko tinggi dalam transportasi ke konsumen.

Abstract
Background Acute myeloid leukemia is the most common acute leukemia in adults with an unacceptably low cure rate. In recent years a number of new treatment strategies and compounds were developed for the treatment of acute myeloid leukemia. There were several randomized, controlled clinical trials with the objective to improve patients’ management and patients’ outcome in acute myeloid leukemia. Unfortunately, these trials are not always directly comparable, as they do not measure the same outcomes and currently there are no core outcome sets that can be utilized to guide outcome selection and harmonization in this disease area. The HARMONY Alliance is a public-private European Network established in 2017, which currently includes 53 partners and 32 associated members from 22 countries. Amongst many other goals of the HARMONY Alliance, Work Package 2 focuses on defining outcomes that are relevant to each hematological malignancy. In accordance, a pilot study will be performed to define core outcome set in acute myeloid leukemia. Methods The pilot study will use a three-round Delphi survey and a final consensus meeting to define a core outcome set. Participants will be recruited from different stakeholder groups, including patients, clinicians, regulators and members of the European Federation of Pharmaceutical Industries and Associations (EFPIA). At the pre-Delphi stage a literature research was conducted followed by several semi-structured interviews of clinical public and private key opinion leaders. Subsequently the preliminary outcome list was discussed in several multi-stakeholder face-to-face meetings. The Delphi survey will reduce the preliminary outcome list to essential core outcomes. After completing the last Delphi round a final face-to-face meeting is planned to achieve consensus about core outcome set in acute myeloid leukemia. Discussion The pilot Delphi as part of HARMONY Alliance aims to define a core outcome set in acute myeloid leukemia based on a multi-stakeholder consensus. Such a core outcome set will help to allow consistent comparison of future clinical trials and real world evidence research and ensures that appropriate outcomes valued by a range of stakeholders are measured within future trials.

Abstract
Introduction: Increasing smartphone use among adolescents in todays’ world has made this handy device an indispensable electronic tool, however, it comes at a price of problematic overuse or addiction. We aim to investigate the prevalence of smartphone addiction among undergraduate medical students and explore its association with various demographic and personal factors. Methods: A pool of 250 undergraduate students completed a survey composed of socio-demographics information, smartphone-use related variables and 10-point Smartphone Addiction Scale-Short Version in February 2019. Results: Smartphone addiction among medical students was estimated at around 36.8% with higher percentage of male smartphone addicts. Phubbing was reported by 37.6% participants with more than 60% reporting overuse. Statistically significant association was observed between smartphone addiction and gender and overuse. Self-acknowledgement of addiction was found to be the biggest predictor of smartphone addiction. Conclusion: This study provides preliminary insights into smartphone use, smartphone addiction and various factors predicting smartphone addiction among early undergraduate medical students from Nepal, which should be extended in future studies. Education policymakers and educators need to develop some strategies encouraging student’s smartphone utilization to enhance academic performance.

Abstract
Background: Inpatient status has been shown to be a predictor of poor bowel preparation for colonoscopy; however, the optimal bowel preparation regimen for hospitalized patients is unknown. Our aim was to compare the efficacy of bowel preparation volume size in hospitalized patients undergoing inpatient colonoscopy.

Methods: This prospective, single blinded (endoscopist), randomized controlled trial was conducted as a pilot study at a tertiary referral medical center. Hospitalized patients undergoing inpatient colonoscopy were assigned randomly to receive a high, medium, or low-volume preparation. Data collection included colon preparation quality, based on the Boston Bowel Preparation Scale, and a questionnaire given to all subjects evaluating the ability to completely finish bowel preparation and adverse effects (unpleasant taste, nausea, and vomiting).

Results: Twenty-five colonoscopies were performed in 25 subjects. Patients who received low-volume preparation averaged a higher mean total BBPS (7.4, SD 1.62), in comparison to patients who received high-volume (7.0, SD 1.41) and medium-volume prep (6.9, SD 1.55), P = 0.77. When evaluating taste a higher score meant worse taste. The low-volume group scored unpleasant taste as 0.6 (0.74), while the high-volume group gave unpleasant taste a score of 2.2 (0.97) and the medium-volume group gave a score of 2.1 (1.36), P < 0.01.

Conclusion: In this pilot study, the low-volume colon preparation Prepopik® may be preferred in the inpatient setting due its better rate of tolerability and comparable bowel cleanliness when compared to larger volume preparation, although we cannot overreach any definitive conclusion. Further more robust studies are required to confirm these findings.

Abstract
Introduction HIV-positive women who are still in the reproductive years need adequate sexual and reproductive health information to make informed reproductive health choices. However, many HIV-positive women who interface with the health system continue to miss out on this information. We sought to: a) determine the proportion of HIV-positive women enrolled in HIV care who missed family planning (FP) counselling; and b) assess if any association existed between FP counseling and current use of modern contraception to inform programming. Methods Data were drawn from a quantitative national cross-sectional survey of 5,198 HIV-positive women receiving HIV care at 245 HIV clinics in Uganda; conducted between August and November 2016. Family planning counseling was defined as receipt of FP information by an HIV-positive woman during ANC, at the time of delivery or at the PNC visit. Analyses on receipt of FP counseling were done on 2,760 HIV-positive women aged 15-49 years who were not currently pregnant and did not intend to have children in the future. We used a modified Poisson regression model to determine the Prevalence Ratio (PR) as a measure of association between receipt of any FP counseling and current use of modern contraception, controlling for potential confounders. Analyses were performed using STATA statistical software, version 14.1. Results Overall, 2,104 (76.2%) HIV-positive women reported that they received FP counseling at any of the three critical time-points. Of the 24% ( n =656) who did not, 37.9% missed FP counseling at ANC; 41% missed FP counseling during delivery; while 54% missed FP counseling at the post-natal care visit. HIV-positive women who received any FP counseling were significantly more likely to report current use of modern contraception than those who did not (adjusted PR [adj. PR] = 1.21; 95% Confidence Interval [CI]: 1.10, 1.33). Conclusion Nearly one-quarter of HIV-positive women did not receive any form of FP counseling when they interfaced with the healthcare system. This presents a missed opportunity for prevention of unintended pregnancies, and suggests a need for the integration of FP counseling into HIV care at all critical time-points.

Abstract
Background Heart rate variability (HRV) decreases in Parkinson’s disease (PD) and it can be considered a marker for cardiovascular dysautonomia. Purpose To evaluate long-term time-domain analysis of HRV of PD patients and compare the results with those of matched healthy individuals. Method Idiopathic PD patients without comorbidity impairing HRV, and age-matched healthy individuals were recruited in a pilot study. A long-term time domain analysis of HRV using 24-hour ambulatory ECG was performed. Results Overall, 18 PD patients fulfilling inclusion criteria completed the evaluation (mean age was 55.6 ±8.8, disease duration: 5.0±4.7). Mean SCOPA-AUT score was 10.1±7.3. Patients were on Hoehn & Yahr stage 1-2 and mean Levodopa Equivalent Dose (LED) was 311 ± 239.9. Mean of the 5-minute standard deviation (SD) of R-R intervals distribution (SDNN) for all 5 min segments of the entire recording (ISDNN) was significantly lower in patients compared to controls. ISDNN was significantly different between Parkinson’s disease patients and healthy controls.Conclusion In our population characterized by mild to moderate disease severity, time-domain assessment of HRV seemed to be a potential tool to characterize cardiovascular dysautonomia. Decrease of ISDNN in PD may reflect an autonomic derangement extending all day and night long.
