Microplastics are plastic particles less than 5 mm in length. Microplastics in the air can be ingested and inhaled by humans. In this work, three sites in a roadside area were investigated for microplastics. Air samples were obtained by sucking air at these three sites into a stainless steel funnel with a vacuum pump. The air went through a filter media to retain any particles, which were then collected and observed with a digital microscope and Fourier Transform Infrared (FTIR) testing. A diversity of microplastic shapes were identified at the sites, including fibres, fragments and films. Pellets were not found at any sites, and fibre was the dominant microplastic shape. The highest microplastic was found in the study site with high traffic volume than at sites with low traffic volume. Microplastic on Urip Sumoharjo street (225,087 units/day) as many as 174.97 particles/m3 and 130.50 particles/m3, Mayjend Sungkono street (132,066 units/day) as many as 131.75 particles/m3 and 68.36 particles/m3, and Embong Malang street (98,017 units/day) as much 94.69 particles/m3 and 55.93 particles/m3. Microplastics from different polymers, such as polyethene terephthalate (PET), polyester and cellophane, were identified. Thus, dust emissions and depositions in the air, on land surfaces, and in aquatic environments are associated with microplastic transportation.

To better prepare the professionals and scholars of tomorrow in the field of communication sciences and disorders (CSD), a research project in which undergraduate students collected and analyzed language samples of child-parent dyads is presented. Student researchers gained broad and discipline-specific inquiry skills related to the ethical conduct of research, the literature review process, data collection using language assessment techniques, language sample analysis, and research dissemination. Undergraduate students majoring in CSD developed clinical research knowledge, skills, and dispositions necessary for future graduate level study and professional employment. In addition to the benefits of student growth and development, language samples collected through this project are helping to answer research questions regarding communicative turn-taking opportunities within the everyday routines of young children, the effects of turn-taking interactions on language development, and the construct validity of language sampling analysis techniques.

Problem Solving Task

This study compared individuals with pairs in a scientific problem-solving task. Participants interacted with a virtual psychological laboratory called Virtue to reason about a visual search theory. To this end, they created hypotheses, designed experiments, and analyzed and interpreted the results of their experiments in order to discover which of five possible factors affected the visual search process. Before and after their interaction with Virtue, participants took a test measuring theoretical and methodological knowledge. In addition, process data reflecting participants’ experimental activities and verbal data were collected. The results showed a significant but equal increase in knowledge for both groups. We found differences between individuals and pairs in the evaluation of hypotheses in the process data, and in descriptive and explanatory statements in the verbal data. Interacting with Virtue helped all students improve their domain-specific and domain-general psychological knowledge.

A free text data collection system has been developed at the University of Illinois utilizing single word, syntax free dictionary lookup to process data for retrieval. The source document for the system is the Surgical Pathology Request and Report form. To date 12,653 documents have been entered into the system.The free text data was used to create an IRS (Information Retrieval System) database. A program to interrogate this database has been developed to numerically coded operative procedures. A total of 16,519 procedures records were generated. One and nine tenths percent of the procedures could not be fitted into any procedures category; 6.1% could not be specifically coded, while 92% were coded into specific categories. A system of PL/1 programs has been developed to facilitate manual editing of these records, which can be performed in a reasonable length of time (1 week). This manual check reveals that these 92% were coded with precision = 0.931 and recall = 0.924. Correction of the readily correctable errors could improve these figures to precision = 0.977 and recall = 0.987. Syntax errors were relatively unimportant in the overall coding process, but did introduce significant error in some categories, such as when right-left-bilateral distinction was attempted.The coded file that has been constructed will be used as an input file to a gynecological disease/PAP smear correlation system. The outputs of this system will include retrospective information on the natural history of selected diseases and a patient log providing information to the clinician on patient follow-up.Thus a free text data collection system can be utilized to produce numerically coded files of reasonable accuracy. Further, these files can be used as a source of useful information both for the clinician and for the medical researcher.

he purpose of this study was to increase the activities and results of Indonesian language learning in the exposition text material of class X IS 3 SMAN 4 Banda Aceh. The learning model used in this study is the CTL learning model. The subjects of this study were students of class X IS 3 SMAN 4 Banda Aceh. The number of students is 35 students with 16 male students and 19 female students. This research was conducted in the 2019/2020 school year for a period of 3 months, from August 2019 to October 2019 in the odd semester. The research methodology is Classroom Action Research (PTK) consisting of two cy-cles and each cycle consisting of two meetings. Each cycle consists of planning, implementing, observ-ing and reflecting. The data collection technique is to collect test scores that are carried out at the end of each lesson in each cycle using a question instrument (written test). Observation data was carried out by looking at the activeness of students in the learning process. Data were analyzed by means of percentage statistics. The results showed that there was an increase in student learning activities in both cycles, from good enough to good categories and to very good categories. Completeness of student learning outcomes has increased from 48.57% in the pre cycle increased to 68.57% in cycle I and increased to 88.57% in cycle II. The use of the CTL learning model can increase the activities and results of Indone-sian language learning in the exposition text material of class X IS 3 SMAN 4 Banda Aceh Academic Year 2019/2020
