PEMBELAJARAN IPA (FISIKA) HARATI BERORIENTASI PADA PENDEKATAN ILMIAH DAN NILAI MORAL
Authors: Hartanto Theo Jhoni
Published: April 2019

Abstract: There are two findings found by the author from the observation related to science (physics) learning activities in several Junior High Schools (SMP) at Palangka Raya city. The first one, science learning tends to be more focused to the teachers, so that most students thought that science (physics) as the subject which is hard to understand. The second one, science (physics) teachers have not completely done their duty yet to plant  some moral values inside the students’ mind. Generally, the learning activities only focused to the cognitive aspect. Based on those two findings, science instruction which is interested from product, process, and attitude, need to be applied. Therefore, this article was presented to describe the harati instruction which try to balance between the “thingking” and the “feeling” aspect in science (physics) learning practice in Junior High School (SMP)Key Words: moral value, harati instruction Abstrak: Ada dua hasil observasi yang ditemukan penulis berkaitan dengan kegiatan pembelajaran IPA (fisika) di sekolah menengah pertama (SMP) di Kota Palangka Raya. Pertama pembelajaran IPA cenderung lebih berpusat pada guru sehingga sebagian besar siswa menganggap mata pelajaran IPA (fisika) sebagai mata pelajaran yang sulit dipahami. Hal ini berefek pada hasil belajar siswa yang tidak sesuai dengan harapan. Kedua, guru IPA (fisika) belum sepenuhnya melaksanakan tugasnya sebagai pendidik yang bertanggung jawab untuk menanamkan nilai moral dalam diri siswa. Umumnya pembelajaran hanya fokus kepada aspek kognitif. Berdasarkan dua hal tersebut, pembelajaran IPA yang sesuai dengan hakikatnya sebagai produk, proses, dan sikap yang terintegrasi perlu untuk dilakukan. Oleh sebab itu, artikel ini hadir untuk memaparkan pembelajaran harati, yaitu pembelajaran yang mengupayakan keseimbangan  antara  aspek  “pikir”  dengan “hati” dalam praktik pembelajaran IPA (fisika) di SMP.Kata Kunci: nilai moral, pembelajaran harati

A field study was undertaken to (i) measure the prevalence of feline leukaemia virus (FeLV) exposure and FeLV infection in a cross-section of healthy Australian pet cats; and (ii) investigate the outcomes following natural FeLV exposure in two Australian rescue facilities. Group 1 (n = 440) consisted of healthy client-owned cats with outdoor access, predominantly from eastern Australia. Groups 2 (n = 38) and 3 (n = 51) consisted of a mixture of healthy and sick cats, group-housed in two separate rescue facilities in Sydney, Australia, tested following identification of index cases of FeLV infection in cats sourced from these facilities. Diagnostic testing for FeLV exposure/infection included antigen (p27) testing with three different point-of-care FeLV kits and a laboratory-based ELISA, real-time polymerase chain reaction (qPCR) testing, real-time reverse-transcription PCR (qRT-PCR) testing, and neutralising antibody (NAb) testing. Cats were classified as FeLV-uninfected (FeLV-unexposed and presumptively FeLV-abortive infections) or FeLV-infected (presumptively regressive and presumptively progressive infections). In Group 1, 370 FeLV-unexposed cats (370/440, 84%), 47 abortive infections (47/440, 11%), nine regressive infections (9/440, 2%) and two progressive infections (2/440, 0.5%) were identified, and 12 FeLV-uninfected cats (12/440, 3%) were unclassifiable as FeLV-unexposed or abortive infections due to insufficient sample available for NAb testing. In Groups 2 and 3, 31 FeLV-unexposed cats (31/89, 35%), eight abortive infections (8/89, 9%), 22 regressive infections (22/89; 25%) and 19 progressive infections (19/89; 21%) were discovered, and nine FeLV-uninfected cats (9/89; 10%) were unclassifiable due to insufficient sample available for NAb testing. One of the presumptively progressively-infected cats in Group 3 possibly had a focal FeLV infection. Two other presumptively progressively-infected cats in Group 3 may have been classified as regressive infections with repeated testing, highlighting the difficulties associated with FeLV diagnosis when sampling cats at a single time point, even with results from a panel of FeLV tests. These results serve as a reminder to Australian veterinarians that the threat of FeLV to the general pet cat population remains high, thus vigilant FeLV testing, separate housing for FeLV-infected cats and FeLV vaccination of at risk cats is important, particularly in group-housed cats in shelters and rescue facilities, where outbreaks of FeLV infection can occur.

With the rapid progress of genetic engineering and gene therapy, World Anti-Doping Agency has alerted to gene doping and prohibited its use in sports. However, there is no standard method available yet for detection of transgenes delivered by recombinant adenoviral (rAdV) vectors. Here we aimed to develop a detection method for transgenes delivered by rAdV vectors in a mouse model that mimics gene doping. rAdV vectors containing mCherry gene was delivered in mice through intravenous injection or local muscular injection. After five days, stool and whole blood samples were collected, and total DNA was extracted. As additional experiments, whole blood was also collected from mouse tail tip until 15 days from injection of the rAdv vector. Transgene fragments from different DNA samples were analyzed using semi-quantitative PCR (sqPCR), quantitative PCR (qPCR), and droplet digital PCR (ddPCR). In the results, transgene fragments could directly be detected from blood cell fraction-DNA, plasma-cell free DNA and stool-DNA by qPCR and ddPCR, depending on specimen type and injection methods. We observed that a combination of blood cell fraction-DNA and ddPCR was more sensitive than other combinations used in this model. These results could accelerate the development of detection methods for gene doping.

Authors: Kumar Vijay , Kim You-Sam , Kim Jong-Joo
Published: April 2019

Aim: This review illustrates bisphenols toxicity and its effect on organ toxicity and its pathogenicity. Summary: Bisphenols are widely used in the synthesis of polycarbonates plastic and, epoxy resins and thermal paper, which are used in the manufacturing of daily used items. Packed food and drinks are the main sources of exposure to bisphenols. These chemicals affect human and animal by disrupting the function of estrogen, androgen, aryl hydrocarbon, and another receptor. These chemicals exert various harmful effects because its interaction with receptors, generates ROS, lipid peroxidation, mitochondrial dysfunction, alters cell signaling and inhibits DNA methylation. Both cohort and case-control studies have shown an association between bisphenols exposure and increased risk of cardiovascular disease, neurological disorder, reproductive abnormalities, obesity, and diabetes. Continuous exposure to bisphenols is related to worsening effects during the development of the animal. These chemicals also affect the immune cells and play a significant role in the initiation of the inflammatory response. Conclusion: Bisphenols exposure exhibit age, gender, and dose-dependent effect. Even a low concentration of bisphenols shows the deteriorating effect and hence deserve the critical assessment for their uses. Bisphenols shows global influence on human health and needs to discover the underlying pathways involved in all disease condition.

Exploring problem decomposition and program development through block-based programs
Authors: Kwon Kyungbin , Cheon Jongpil
Published: April 2019

Although teachers need to assess computational thinking (CT) for computer science education in K-12, it is not easy for them to evaluate studentsâ€™ programs based on the perspective. The purpose of this study was to investigate studentsâ€™ CT skills reflected in their Scratch programs. The context of the study was a middle school coding club where seven students voluntarily participated in a five-week coding activity. A total of eleven Scratch programs were analyzed in two aspects: problem decomposition and program development. Results revealed that students demonstrated proper decompositions of problems, which supported program development processes. However, in some cases, students failed to decompose necessary parts as their projects got sophisticated, which resulted in the failure or errors of programs. Regarding program development, algorythmic thinking had been identified as the area to be improved. Debugging and evaluation of programs were the necessary process students needed to practice. Implications for teaching CT skills were discussed.

Published: April 2019

Background

Mobile health (mHealth) apps demonstrate promise for improving sleep at scale. End-user engagement is a prerequisite for sustained use and effectiveness.

Objective

We assessed the needs and preferences of those with poor sleep and insomnia to inform the development of an engaging sleep app.

Methods

We triangulated results from qualitative (focus groups and app reviews) and quantitative (online survey) approaches. A total of 2 focus groups were conducted (N=9). An online survey tested themes identified from the focus groups against a larger population (N=167). In addition, we analyzed 434 user reviews of 6 mobile apps available on app stores.

Results

Common focus group themes included the need to account for diverse sleep phenotypes with an adaptive and tailored program, key app features (alarms and sleep diaries), the complex yet condescending nature of existing resources, providing rationale for information requested, and cost as a motivator. Most survey participants (156/167, 93%) would try an evidence-based sleep app. The most important app features reported were sleep diaries (148/167, 88%), sharing sleep data with a doctor (116/167, 70%), and lifestyle tracking (107/167, 64%). App reviews highlighted the alarm as the most salient app feature (43/122, 35%) and data synchronization with a wearable device (WD) as the most commonly mentioned functionality (40/135, 30%).

Conclusions

This co-design process involving end users through 3 methods consistently highlighted sleep tracking (through a diary and WD), alarms, and personalization as vital for engagement, although their implementation was commonly criticized in review. Engagement is negatively affected by poorly designed features, bugs, and didactic information which must be addressed. Other needs depend upon the type of user, for example, those with severe insomnia.

Shared Services Center have been developing well for the last few years in Poland as well as in the world. Advantages of the centralization of the processes 'back-office' in private businesses are not insignificant, therefore this solution have been introduced and recommended to the local government units. The main purpose of this article was to diagnose if the centralization of support processes for commune educational institutions in the voivodeships Podkarpackie in Shared Service Centers, brings effects in the form of lowering costs handling these processes. After analyzing the data, the results confirming the thesis were obtained. In the studied period of years 2014-2017, despite rising expenes for education, the direct costs related to employees servicing support processes were decreasing. It causes the necessity of insightful analysis of the problem from different aspects, but it also allows us to suppose that the implementation of solutions developed in education system would also be effective in other areas of activity of local government units, which would optimalize costs and bring significant savings.

The hood is an alternative to overcome the high intensity of sunlight. In this study the type of containment material treatment can be divided into 3 types of containment material, namely the type of plastic lid material, paranet and combination. For microclimate measurements, a temperature and humidity meter and a light meter are used. Microclimate measurements were carried out at 12.00 WITA, on cayenne pepper from 7 days to 35 HTS. Micro climate data analysis is done by interpolation to obtain the profile contour lines. The results of the study showed that there were different shapes and distribution of different micro-climate profile contours, especially in light intensity. At air temperature and air humidity can not obtain contour lines, because the results of the data from the research conducted are not much different. Plant growth rates in each treatment showed different productivity. In this type of paranet lid material shows better results compared to the type of plastic hood and combination material. In this type of paranet lid material produces an average dry weight of 247.9 grams.

Keywords: hood type material, cayenne pepper plant, microclimate.
