Identifying Barriers to Engagement in Participatory Culture: Privacy and Other Affective Concer
Jenifer Sunrise Winter APEC국제교육협력원 2011 Asia-Pacific Cybereducation Journal Vol.7 No.1
This paper addresses barriers to participatory culture by examining the activities and concerns of twenty-eight undergraduate students enrolled in a social media course. Analysis of self-reported activities related to four dimensions of participatory culture literacy as outlined by Jenkins et al. (2009) revealed that many do not fully engage in participatory culture. While the barriers identified included mention of access issues or a lack of knowledge, most of the concern was with affective issues, including privacy concerns and the perception that they have nothing useful to contribute (or that their contributions will not be welcomed). It is recommended that instructional activities focus on building affective competencies related to participatory culture.
Highly stable, ultra-thin Au embedded zinc tin oxide multilayer transparent conductive thin films
Jenifer K.,Parthiban S. 한국물리학회 2023 Current Applied Physics Vol.53 No.-
Transparent conducting thin films (TCFs) with excellent stability and good mechanical properties, room temperature processing, as well as owing high transparency and conductivity, have become an essential requirement in numerous applications. Here, we report the fabrication of room temperature processed Au-embedded zinc tin oxide (ZTO) multilayer transparent conducting thin films on glass and polycarbonate substrates by radio frequency magnetron sputtering. A detailed investigation on the correlation of optical and electrical properties of the ZTO/Au/ZTO (ZGZ) multilayer thin films, with the thickness of individual layers was carried out. The ZGZ thin films showed excellent performance under various stability tests. To evaluate the commercial application capabilities in aircraft canopies and other optoelectronic devices, the fabricated ZGZ multilayer TCFs was subjected to electromagnetic interference (EMI) shielding studies. The ZGZ thin film exhibited EMI shielding effectiveness of 24.75 dB in the X-band region, yielding 99.66% power attenuation.

Background: According to the National Family Health Survey– 4, in India, 78.9% of deliveries occur in institutions, although only 42.6% of new mothers initiate breastfeeding within 1 hour of delivery.Purpose: To estimate the proportion of early initiation of breastfeeding (EIBF) among new mothers at discharge from a tertiary care hospital and identify the determinants of delayed initiation of breastfeeding among them.Methods: This was a hospital-based analytical cross-sectional study of 108 new mothers. After obtaining Institutional Review Board approval and informed consent, we interviewed the new mothers on the day of discharge. Multivariate logistic regression was performed using IBM SPSS Statistics ver. 24.Results: The median breastfeeding initiation time was 90 minutes (interquartile range, 30–180 minutes). Overall, 43.5% of the mothers practiced EIBF, 77.4% practiced exclusive breastfeeding, and 43.5% were rooming in at discharge. Reasons for breastfeeding delays included extended recovery time from spinal anesthesia, maternal lassitude, and uncomfortable breastfeeding position due to post-cesarean pain. In the multivariate analysis, a birth weight less than 2,500 g (adjusted odds ratio [aOR], 4.33; 95% confidence interval [CI], 1.12–16.82; P=0.03), cesarean section delivery (aOR, 4.68; 95% CI, 1.57– 13.92; P=0.005), and mother’s poor knowledge of breastfeeding (aOR, 4.61; 95% CI, 1.44–14.72; P=0.010) were more likely to delay the initiation of breastfeeding.Conclusion: EIBF was practiced by less than half of the new mothers as determined by the cesarean section, baby’s birth weight, and mothers’ awareness of breastfeeding. Thus, it is vital to improve breastfeeding and nutritional counseling among mothers during the antenatal period and improve healthcare professionals’ training to facilitate EIBF, even in circumstances such as cesarean section.
AERODYNAMIC EFFECTIVITY ON THE MOVING OF HELICAL WINDMILL AS A SOURCE OF ALTERNATIVE ENERGY
Hertanto,Jenifer Taniya Maria 국제과학영재학회 2015 APEC Youth Scientist Journal Vol.7 No.2
The need of electrical energy is still depend on the fossil energy. Based on the data, Indonesian fossil energy reserves are decreasing, example oil reserves are merely enough for the next 23 years. While gas reserves are assumed will last until 50 years into the future and then coal for the next 80 years. If Indonesia only depends on fossil energy sources for the next 23-80 years, Indonesia will face a lack of energy supply. Therefore to overcome the case above, there is should be an effort to produce a renewable energy.. In this research, we took the initiative to take advantage of the wind gusts from the passing motor vehicles using helical windmill to overcome the unstable wind speed as an alternative source for lighting on roads, especially highways. The purpose of this study is to improve the effectivity of aerodynamic to the moving helical windmill as a source of an alternative energy.And the advantage of this blade is it can rotate continuously because it can recieve the wind from all direction and although the wind energy is very small the blade can still rotate. This study begins with designing a helical windmill, then a generator which is able to convert wind power into electricity. The generator designed consists of eight coils (1000 windings per coil), a saving current using 6 volt of battery, 1 ampere of transformer and the maximum rotation obtained is 12 volts. From this research, it can be concluded that the rotation speed of 367 rpm will produce 6.1 volts voltage, rotation speed of 406 rpm will produce 6.8 volts voltage, and rotation speed of 451 will be obtained 7.3 volts voltage.

Let G = (V (G), E(G)) be a graph and let g : V (G) → S3 be a function. For each edge xy assign the label r where r is the remainder when o(g(x)) is divided by o(g(y)) or o(g(y)) is divided by o(g(x)) according as o(g(x)) ≥ o(g(y)) or o(g(y)) ≥ o(g(x)). The function g is called a group S3 cordial remainder labeling of G if |vg(i)-vg(j)| ≤ 1 and |eg(1)-eg(0)| ≤ 1, where vg(j) denotes the number of vertices labeled with j and eg(i) denotes the number of edges labeled with i (i = 0, 1). A graph G which admits a group S3 cordial remainder labeling is called a group S3 cordial remainder graph. In this paper, we prove that square of the path, duplication of a vertex by a new edge in path and cycle graphs, duplication of an edge by a new vertex in path and cycle graphs and total graph of cycle and path graphs admit a group S3 cordial remainder labeling.
