Faktor-Faktor Yang Berhubungan Dengan Penggunaan Metode Kontrasepsi Implant Di Wilayah Kerja Puskesmas Teladan Kecamatan Medan Kota Tahun 2017
No full textTotal fertility rate has declined globally but running very slowly, it is
occurred because of the low use of long-term contraception. Long Term implant
cotraception methodis more effective to control the population by preventing
unwanted pregnancy. The aim of this study is to determine the factors related to
the using of implants contraception method among women in reproductive ageat
Puskesmas Teladan of Medan.
This study use dacross-sectional analytic and number of sample is 42
women in reproductive age (PUS) which selected by systematic random sampling.
Data analysis was done by using univariate, bivariate with chi square test and
multivariate logistic regression.
It can be assumed that the percentage of implant use in women of
reproductive age (PUS) at Puskesmas teladan of Medan was 35,7%. Variables
that have a statistically significant correlation to the use of implants are implant
knowledge (OR=20.4;95% CI=4.8to180), role model (OR=5.3;95%CI=2.4
to12.3) and cultural values (OR=2.9;95%CI=1.3to7.4). 34% possibility of
implant use relates to some variables, they are cultural values, implants
knowledge and role model. Most related factors for implants use is good
knowledge about implants.
The factors related to implant use in women of reproductive age (PUS) at
Puskesmas Teladan of Medan have correlation with supported cultural values,
good knowledge of the implant and role model who use implant. Some Efforts to
facilitate the provision of information for women in reproductive age (PUS) are
done by involving community leaders and religious leaders are regarded as role
model and to avoid a miss perception about family planning based on their
religion.Penurunan angka kesuburan total terjadi secara global namun sangat lambat
oleh karena rendahnya penggunaan kontrasepsi jangka panjang. Metode
kontrasepsi jangka panjang (MKJP) implant lebih efektif dalam mengendalikan
jumlah penduduk dengan cara mencegah kehamilan yang tidak diinginkan.

Distributed human computation framework for linked data co-reference resolution
No full textDistributed Human Computation (DHC) is a technique used to solve computational problems by incorporating the collaborative effort of a large number of humans. It is also a solution to AI-complete problems such as natural language processing. The Semantic Web with its root in AI is envisioned to be a decentralised world-wide information space for sharing machine-readable data with minimal integration costs. There are many research problems in the Semantic Web that are considered as AI-complete problems. An example is co-reference resolution, which involves determining whether different URIs refer to the same entity. This is considered to be a significant hurdle to overcome in the realisation of large-scale Semantic Web applications. In this paper, we propose a framework for building a DHC system on top of the Linked Data Cloud to solve various computational problems. To demonstrate the concept, we are focusing on handling the co-reference resolution in the Semantic Web when integrating distributed datasets. The traditional way to solve this problem is to design machine-learning algorithms. However, they are often computationally expensive, error-prone and do not scale. We designed a DHC system named iamResearcher, which solves the scientific publication author identity co-reference problem when integrating distributed bibliographic datasets. In our system, we aggregated 6 million bibliographic data from various publication repositories. Users can sign up to the system to audit and align their own publications, thus solving the co-reference problem in a distributed manner. The aggregated results are published to the Linked Data Cloud
Intersystem soft handover for converged DVB-H and UMTS networks
No full textDigital video broadcasting for handhelds (DVB-H) is the standard for broadcasting Internet Protocol (IP) data services to mobile portable devices. To provide interactive services for DVB-H, the Universal Mobile Telecommunications System (UMTS) can be used as a terrestrial interaction channel for the unidirectional DVB-H network. The converged DVB-H and UMTS network can be used to address the congestion problems due to the limited multimedia channel accesses of the UMTS network. In the converged network, intersystem soft handover between DVB-H and UMTS is needed for an optimum radio resource allocation, which reduces network operation cost while providing the required quality of service. This paper deals with the intersystem soft handover between DVB-H and UMTS in such a converged network. The converged network structure is presented. A novel soft handover scheme is proposed and evaluated. After considering the network operation cost, the performance tradeoff between the network quality of service and the network operation cost for the intersystem soft handover in the converged network is modeled using a stochastic tree and analyzed using a numerical simulation. The results show that the proposed algorithm is feasible and has the potential to be used for implementation in the real environment

One step preparation of pure tau-MnAl phase with high magnetization using strip casting method
No full textFerromagnetic phase of Mn-Al exhibits great potential in the rare-earth free permanent magnetic materials due to its high magnetocrystalline anisotropy, high magnetization, high Curie temperature and low cost. In this work, the strip casting technique was applied to prepare MnAl magnetic phase. X-ray diffraction and energy dispersive X-ray analyses indicate that the as-prepared Mn54Al46 strip sample consists of pure tau-MnAl magnetic phase. It is found that the composition of Mn54Al46 is suitable to prepare tau-MnAl phase during the strip casting process. The Mn54Al46 strip sample synthesized through the strip casting exhibits a fairly high magnetization of 114 emu/g under a field of 5 T, while the coercivity of iHc = 2.8 kOe, magnetization of M-5T = 63.9 emu/g at room temperature can be obtained for Mn54Al46 powder sample. This preparation method can produce a large amount of tau-phase MnAl alloy and promote mass industrialized production. (C) 2017 Author(s)
Turbulent skin-friction drag reduction by travelling waves induced by spanwise Lorentz force
No full textThe streamwise and spanwise travelling waves induced by spanwise Lorentz force are studied for skin-friction drag reduction in a turbulent channel. The streamwise travelling wave by spanwise Lorentz force on drag reduction is compared to the with the spanwise wall motion. The drag reduction map shows a drag reduction region and a drag increase region, depending on a time scale . For spanwise travelling wave, a large drag reduction appears at large oscillation frequencies and small spanwise wave numbers, while all stationary wave cases give a drag increase. When the wave travels at an oblique angle to the streamwise mean flow, the optimal drag reduction appears in backward travelling wave case. Generally, the backward streamwise travelling wave is found to be most efficient in drag reduction among all oblique travelling waves. Spanwise oscillation, forward streamwise travelling, spanwise travelling and backward streamwise travelling wave cases share a similar drag reduction mechanism: first, the spanwise motion directly breaks the near wall quasi-streamwise vortices structure array \cite{Jeong_etal1997}, which results in the shortening of streamwise streaks; second, the spanwise velocity layer maintains the asymmetry of the positive and negative quasi-streamwise vortices, which leads to a sustained drag reduction
