Published: June 2018

Dalam suatu bisnis diperlukan upaya memaksimalkan keuntungan diantaranya dengan melakukan promosi. Banyak cara yang bisa dilakukan untuk mempromosikan produk seperti dengan cara online dengan memanfaatkan media sosial Facebook dan situs-situs yang menyediakan iklan. Namun demikian, untuk memperoleh hasil yang maksimal maka perlu dilakukan perhitungan seberapa besar kemungkinan pelanggan akan tertarik terhadap produk yang ditawarkan. Penelitian ini bertujuan untuk menerapkan data mining untuk promosi produk Distro Nasional. Dalam bidang keilmuan data mining, terdapat suatu metode yang dinamakan association rule. Metode ini bertujuan untuk menunjukkan nilai asosiatif antara jenis-jenis produk yang dibeli oleh pelanggan sehingga terlihatlah suatu pola berupa produk apa saja yang sering dibeli oleh palanggan tersebut. Dengan mengetahui jenis produk yang sering dibeli maka dapat dibuat sebagai sebuah dasar keputusan untuk menentukan produk apa saja yang cocok untuk dipromosikan kepada pelanggan tersebut. Algoritma Apriori juga akan dipergunakan untuk menentukan frequent itemset sehingga hasil akhir yang dicapai yaitu untuk menghitung persentase ketertarikan (confindence) pelanggan terhadap produk yang ditawarkan.Kata kunci: promosi, data mining, association rule, produk In a business, there is required efforts to maximize profits include by promotion. Many ways can be conducted in promoting a product such as by using Facebook as an online social media and sites which provide advertisements. On the other hand, in gaining a maximum result is required a calculation about how big customer probability to get interested in a product offered. This study aims to apply data mining for product promotion of Distro Nasional store. In a science of data mining there is a method called association rule. This method was intended to indicate associative values among product types were bought by customers. So that, it can be seen a pattern which types of product that often bought by customers. By knowing that information it can be made as a decission base to determine which appropriate products get promotted to that customer. Apriori algorithm will also be used to determine the frequent itemset so that the final result achieved is to calculate the percentage of customer interest (confindence) on the product offered.Keywords: promotion, data mining, association rule, product

Background: Clinical features are the important diagnostic tools for the detection of spontaneous intracerebral haemorrhage patients.Objective: The purpose of the present study was to see the clinical profiles of spontaneous intracerebral haemorrhage patients.Methodology: This cross-sectional study was conducted in the Department of Neurology at Dhaka Medical College and Hospital, Dhaka, Bangladesh from July 2012 to June 2014 for a period of two (2) years. Patients with spontaneous intracerebral haemorrhage who were admitted in the Departments of Neurology, Neurosurgery and Medicine at Dhaka Medical College and Hospital, Dhaka were selected as study population. Both male and female patients with the age group of ≥18 years, first ever spontaneous intracerebral haemorrhage and hospital admission within 48 hours of onset were included for this study. The clinical features of the study population were collected after admission of the patients like headache, hemiplegia or paresis, vomiting, and deterioration of consciousness, dysphasia, dysarthria and hemisensory loss.Result: Headache was observed the most frequent complaint in 81.0% (n=79) patients. Hemiparesis or hemiplegia was the most frequent focal neurological deficit in 69.0% (n=68) patients. Vomiting was common also 58.0% (n=57) patients. Twenty five (26.0%) respondents were presented with deterioration of consciousness. Dysphasia/aphasia was found in 15.0% patients. Convulsion was not a common presenting feature (7%).Conclusion: In conclusion headache, vomiting and deterioration of consciousness are the most common form of clinical feature of spontaneous intracerebral haemorrhage.Journal of Current and Advance Medical Research 2018;5(2):64-67
Female human resource professionals’ job embeddedness in relation to commitment foci: An exploratory study
Authors: Potgieter Ingrid L. , Ferreira Nadia 
Published: June 2018

Orientation: Managers and human resource practitioners who are concerned about managing talent as a critical resource need to recognise how employees’ job embeddedness relates to their commitment foci within the organisation. By understanding this relationship, gaps can be identified and talent can be managed optimally.Research purpose: The purpose of the study was, firstly, to establish whether a significant relationship exists between job embeddedness and a set of commitment foci and, secondly, to identify the variables that contribute the most to the relationship.Motivation for the study: Organisations increasingly devote more attention to initiatives that enhance the commitment and job embeddedness of their employees in order to assist in the design of a sound talent management plan to close the talent gaps.Research approach, design and method: A quantitative approach was used in this study, utilising a cross-sectional survey design to achieve the objective of the study. Descriptive statistics, Pearson’s product-moment correlations and canonical correlation analysis were conducted. The participants were primarily black women at an early stage of their career, who were employed in the human resource management field in a professional capacity.Main findings: The results indicated that job embeddedness significantly and positively accounted for the variance in organisational and occupational commitment foci of the participants.Practical and managerial implications: Human resource practitioners and managers need to consider how the job embeddedness of employees – specifically female employees – affects their commitment foci in developing talent management plans as part of the organisational strategy.Conclusions: The findings of the study provided empirical confirmation of theoretical views on the psychological aspects that keep employees embedded in their jobs and how these aspects relate to their commitment foci.
Managers’ listening skills, feedback skills and ability to deal with interference: A subordinate perspective

Published: June 2018

Orientation: Active listening is the single most important contributor to effective communication by managers; however, this is the skill they seem to struggle with the most. Other important skills for effective communication include feedback and the ability to deal with interference.Research purpose: This study’s primary objective was to determine the effectiveness of managers’ listening and feedback skills and their ability to deal with interference during the listening and feedback phases of the communication process as perceived by subordinates with varying educational backgrounds.Motivation for the study: The aim was to improve managers’ communication with their subordinates.Research design, approach and method: The research followed a quantitative descriptive design. A self-administered questionnaire was compiled, a non-probability convenience sample was chosen and 931 usable responses were acquired.Main findings: The results showed that subordinates perceived their managers’ communication competencies to be marginally above average. Managers’ listening and feedback skills were perceived to be better by graduate-level subordinates than by those with only a Grade 12 qualification. Subordinates with a postgraduate degree also had better perceptions of these skills than those with a Grade 12 qualification, although this finding was not statistically significant.Practical and managerial implications: Managers need to be aware that their communication competencies are crucial to their business’s success. Additionally, their subordinates’ perception of the effectiveness of their communication varies according to varying educational levels. Therefore, managers are advised to consciously make greater efforts in their communication with subordinates with lower qualifications.Contribution or value-add: In conclusion, this article will make managers more knowledgeable about potential challenges they may encounter during the communication process regarding listening skills, feedback skills and propensity to deal with interference.
Efficacy of vitamin D supplementation in major depression
Authors: Vellekkatt F , Menon V 
Published: June 2018

Background:
There is a need to develop and periodically evaluate new treatment strategies in major depression due to the high burden of nonresponse and inadequate response to antidepressants.

Aim:
We aimed to assess the effect of vitamin D supplementation on depression symptom scores among individuals with clinically diagnosed major depression.

Materials and Methods:
Electronic search of databases was carried out for published randomized controlled trials in English language, peer-reviewed journals from inception till August 2017. Outcome measure used for effect size calculation was depression symptom scores. Effect sizes for the trials were computed using standardized mean difference (Cohen's d), and I
2 test was used to assess sample heterogeneity. Pooled mean effect sizes were derived using both fixed and random-effects model. Critical appraisal of studies was done using the Cochrane risk of bias assessment tool.

Results:
A total of four trials involving 948 participants were included in the study. In three trials, the intervention group received oral vitamin D supplementation whereas in one parenteral vitamin D was given. Pooled mean effect size for vitamin D supplementation on depressive symptom ratings in major depression was 0.58 (95% confidence interval, 0.45–0.72). The I
2 value for heterogeneity was 0 suggesting low heterogeneity among studies. Egger plot intercept indicated minimal publication bias.

Conclusion:
Vitamin D supplementation favorably impacted depression ratings in major depression with a moderate effect size. These findings must be considered tentative owing to the limited number of trials available and inherent methodological bias noted in few of them.

Abstract. The “Berlin Air quality and Ecosystem Research: Local and long-range Impact of
anthropogenic and Natural hydrocarbons” (BAERLIN2014) campaign was conducted
during the 3 summer months (June–August) of 2014. During this
measurement campaign, both stationary and mobile measurements were undertaken
to address complementary aims. This paper provides an overview of the
stationary measurements and results that were focused on characterization of
gaseous and particulate pollution, including source attribution, in the
Berlin–Potsdam area, and quantification of the role of natural sources in
determining levels of ozone and related gaseous pollutants. Results show that
biogenic contributions to ozone and particulate matter are substantial. One
indicator for ozone formation, the OH reactivity, showed a 31 %
(0.82 ± 0.44 s−1) and 75 % (3.7 ± 0.90 s−1)
contribution from biogenic non-methane volatile organic compounds (NMVOCs) for urban background
(2.6 ± 0.68 s−1) and urban park (4.9 ± 1.0 s−1)
location, respectively, emphasizing the importance of such locations as
sources of biogenic NMVOCs in urban areas. A comparison to NMVOC measurements
made in Berlin approximately 20 years earlier generally show lower levels today for
anthropogenic NMVOCs. A substantial contribution of secondary organic and
inorganic aerosol to PM10 concentrations was quantified. In
addition to secondary aerosols, source apportionment analysis of the organic
carbon fraction identified the contribution of biogenic (plant-based)
particulate matter, as well as primary contributions from vehicles, with a
larger contribution from diesel compared to gasoline vehicles, as well as a
relatively small contribution from wood burning, linked to measured
levoglucosan.

Abstract. Historical in situ sub-daily rainfall observations are essential for the
understanding of short-duration rainfall extremes but records are typically
not readily accessible and data are often subject to errors and
inhomogeneities. Furthermore, these events are poorly quantified in
projections of future climate change making adaptation to the risk of flash
flooding problematic. Consequently, knowledge of the processes contributing
to intense, short-duration rainfall is less complete compared with those on
daily timescales. The INTENSE project is addressing this global challenge by
undertaking a data collection initiative that is coupled with advances in
high-resolution climate modelling to better understand key processes and
likely future change. The project has so far acquired data from over
23 000 rain gauges for its global sub-daily rainfall dataset (GSDR) and has
provided evidence of an intensification of hourly extremes over the US.
Studies of these observations, combined with model simulations, will continue
to advance our understanding of the role of local-scale thermodynamics and
large-scale atmospheric circulation in the generation of these events and how
these might change in the future.

Abstract. We present PCR-GLOBWB 2, a global
hydrology and water resources model. Compared to previous versions of
PCR-GLOBWB, this version fully integrates water use. Sector-specific water
demand, groundwater and surface water withdrawal, water consumption, and
return flows are dynamically calculated at every time step and interact
directly with the simulated hydrology. PCR-GLOBWB 2 has been fully rewritten
in Python and PCRaster Python and has a modular structure, allowing easier
replacement, maintenance, and development of model components. PCR-GLOBWB 2
has been implemented at 5 arcmin resolution, but a version parameterized at
30 arcmin resolution is also available. Both versions are available as
open-source codes on https://github.com/UU-Hydro/PCR-GLOBWB_model
(Sutanudjaja et al., 2017a). PCR-GLOBWB 2 has its own routines for
groundwater dynamics and surface water routing. These relatively simple
routines can alternatively be replaced by dynamically coupling PCR-GLOBWB 2
to a global two-layer groundwater model and 1-D–2-D hydrodynamic models.
Here, we describe the main components of the model, compare results of the 30
and 5 arcmin versions, and evaluate their model performance using Global
Runoff Data Centre discharge data. Results show that model performance of the
5 arcmin version is notably better than that of the 30 arcmin version.
Furthermore, we compare simulated time series of total water storage (TWS) of
the 5 arcmin model with those observed with GRACE, showing similar negative
trends in areas of prevalent groundwater depletion. Also, we find that
simulated total water withdrawal matches reasonably well with reported water
withdrawal from AQUASTAT, while water withdrawal by source and sector provide
mixed results.

Abstract. The Atmospheric River Tracking Method Intercomparison Project
(ARTMIP) is an international collaborative effort to understand and quantify
the uncertainties in atmospheric river (AR) science based on detection
algorithm alone. Currently, there are many AR identification and tracking
algorithms in the literature with a wide range of techniques and conclusions.
ARTMIP strives to provide the community with information on different
methodologies and provide guidance on the most appropriate algorithm for a
given science question or region of interest. All ARTMIP participants will
implement their detection algorithms on a specified common dataset for a
defined period of time. The project is divided into two phases: Tier 1 will
utilize the Modern-Era Retrospective analysis for Research and Applications,
version 2 (MERRA-2) reanalysis from January 1980 to June 2017 and will be
used as a baseline for all subsequent comparisons. Participation in Tier 1 is
required. Tier 2 will be optional and include sensitivity studies designed
around specific science questions, such as reanalysis uncertainty and climate
change. High-resolution reanalysis and/or model output will be used wherever
possible. Proposed metrics include AR frequency, duration, intensity, and
precipitation attributable to ARs. Here, we present the ARTMIP experimental
design, timeline, project requirements, and a brief description of the
variety of methodologies in the current literature. We also present results
from our 1-month “proof-of-concept” trial run designed to illustrate the
utility and feasibility of the ARTMIP project.
Assessment of coastal flooding and associated hydrodynamic processes on the south-eastern coast of Mexico, during Central American cold surge events
Authors: Rey Wilmer , Salles Paulo , Mendoza E. Tonatiuh , Torres-Freyermuth Alec , Appendini Christian M. 
Published: June 2018

Abstract. Coastal flooding in the northern
Yucatán Peninsula is mainly associated with storm surge events triggered by
high-pressure cold front systems. This study evaluates the hydrodynamic
processes of the Chelem lagoon, Mexico and the flooding threat from cold
fronts for the neighbouring town of Progreso. A 30-year water-level hindcast
(excluding wave set-up) was performed because of the lack of long-term tide
gauge records. In order to assess the relative contribution from wave set-up
and residual and astronomical tides to total flooding, the two worst storm
scenarios in terms of maximum residual tide (Event A) and maximum water level
(Event B) were simulated. Numerical results suggest that during Event A the
wave set-up contribution reaches 0.35 at the coast and 0.17 m inside the
lagoon, and these values are smaller for Event B (0.30 and 0.14 m,
respectively). Results of the effect of the tidal phase on wave set-up and
residual sea level show that (i) the wave set-up contribution increases
during ebb tide and decreases during flood tide at the Chelem inlet, (ii) the
residual tide is larger (smaller) near low (high) or receding (rising) tide,
and (iii) maximum flooding occurs when the storm peak coincides with rising
or high tide. The numerical results confirm the important role of wave set-up
on the assessment of coastal flooding in micro-tidal coastal environments.
Comparison in the follow-up of two patients with persistent elevated PSA and negative prostate biopsy
Authors: Sciarra Alessandro , Panebianco Valeria 
Published: June 2018

Purpose To compare two clinical cases on the follow-up of patients with benign prostatic hyperplasia at risck of progression, negative prostate biopsy and persistent elevated PSA levels. Materials After a first negative prostate biopsy for elevated PSA levels, Case A received dutasteride therapy for benign prostatic hyperplasia, whereas Case B continued his therapy without dutasteride. In both cases, other diagnostic procedures or other biopsies were decided on the basis of PSA level modifications. Results Case A showed a stabilization of PSA levels with a new nadir; the patient did not undergo new biopsies or other diagnostic procedures till the presence (24 months of follow-up) of a PSA elevation despite dutasteride therapy. A new biopsy, then, showed a prostate adenocarcinoma. Case B showed persistent and progressive PSA elevation; the patient underwent other diagnostic procedures and 2 new negative biopsies. Only after 26 months of follow-up a further biopsy showed a prostate adenocarcinoma. Conclusions 5-alpha-reductase inhibitors can reduce the number of unnecessary prostate biopsies.
