Background/Aim. The transobturator tape (TOT) procedure is considered as a gold standard of surgical treatment option for stress urinary incontinence (SUI). The aim of this study was to determine the efficacy of this procedure in the surgical management of SUI by analyzing a single centre short-term results. Methods. From April 2011 until January 2018, 40 patients with predominantly SUI were operated by the standard TOT procedure. A polypropylene tape was placed in the mid-urethra by a percutaneous transobturator approach. The postoperative assessment considered cough tests and post-void residual urine volume at a week following the operation with additional clinical examination and urine culture at one, three and six months. Results. The mean age of the patients was 58 (42?78) years. Predominantly SUI was present in 32 patients (80%) and mixed urine incontinence in 8 patients (20%). At the initial (one week) assessment, the cough test was positive in 3 patients (7.5%), and 4 patients (10%) needed an indwelling urethral catheter because of voiding difficulties. At the second follow-up, 2 (5%) patients still had a positive cough test, 2 patients (5%) had still the need for an indwelling catheter because of significant postvoid residual (PVR) urine volumes and 2 patients (5%) had a positive urine culture. At the three and six months, postoperative assessment. 3 patients (7.5%) still had a positive cough test. After six months 36 patients (90%) were considered as cured, 1 patient (2.5%) improved and 3 patients (7.5%) were classified as a failure. Conclusion. These results concur with the results of the other published short-term studies that analyzed the surgical outcome of the TOT procedure for female urinary incontinence. This allows us to confirm that the transobturator tape technique is a safe, effective and straightforward procedure after adequate training.

Food and Beverage

Many club managers would agree that comparing commercial food and beverage operations to private clubs is like comparing apples to oranges. Clubs are uniquely challenged with multiple dining options (much like a hotel or resort) and in the ability to forecast demand, because many members may not make reservations. Additionally, many club food and beverage operations lose money because of high food and labor costs (more will be said about this later). Finally, club dining is reserved for members only, so clubs are serving a limited market. There are other differences, but these are some of the key ones, all of which present unique challenges. According to research by ClubBenchmarking, 75% of food and beverage departments in clubs lose money. This is not necessarily a good or a bad thing – just a function of how food and beverage in clubs is managed. This chapter will explain how they are managed, how they are similar to (and different from) restaurants, and why so many of them lose money or show a deficit. We will revisit these issues but, first, let’s confirm how important food and beverage is to a club’s livelihood.
People in Clubs

Published: February 2019

In this chapter, we will look at some of the functions of Human Resources Management (HRM) in private clubs. Human resource management encompasses the range of functions which impact employees from recruiting and hiring, to the structure of jobs, to training and development, to performance evaluations and rewards. It also includes administration of employee benefits, salary determination, promotions and transfers, and looking after employee health and safety. And more! It is not the intent of this chapter to provide a comprehensive HRM primer, but rather to provide a snapshot of HRM practices that managers and clubs find useful in day-to-day operations. First, though, we will examine how the management of human resources in clubs is different than it is in other types of hospitality organizations.

Fast Coordination of Power Electronic Converters for Energy Routing in Shipboard Power Systems
Authors: Ginn III H L , Bakos J D , Flinstone Fred , Benigni A
Published: February 2019

A long-term goal of future naval shipboard power systems is the ability to manage energy flow with sufficient flexibility to accommodate future platform requirements such as, better survivability, continuity, and support of pulsed and other demanding loads. To attain this vision of   shipboard energy management, shipboard power and energy management systems must coordinate operation of all major components in real-time. The primary components of a shipboard power system are the generators, energy storage modules, and increasingly power electronics that interface those sources and main load centers to the system. Flexible management of energy flow throughout shipboard distribution systems can be realized by automated coordination of multiple power electronic converters along with storage and generation systems. Use of power converters in power distribution systems has continuously increased due to continued development of the power electronics building blocks (PEBB) concept which reduces cost and increasing reliability of converters. Recent developments in SiC power devices are yielding PEBBs with far greater switching frequencies than Si based devices resulting in an order of magnitude reduction of the time scales as compared to converter systems utilizing conventional IGBT based PEBBs. In addition there have also been advancements in highly modularized converter systems with hundreds of PEBBs such as the Modular Multilevel Converter. Both of those trends have resulted in the continued evolution of the Universal Controller Architecture which attempts to standardize control interfaces for modular power electronic systems.  Further development of interface definitions and increasing communication and computational capabilities of new FPGA based controllers provides opportunities beyond simply supporting SiC PEBBs. Fast control coordination across the system using an appropriate communication architecture provides a degree of energy management not previously realizable in shipboard power systems. The paper will present recent research results in networked control architectures for power electronic converter coordination and control. It will demonstrate that current FPGA and gigabit speed serial communication technologies allow for a very high degree of energy flow control.
No process for initiative
Authors: Parkes G J
Published: February 2019

Throughout naval aviation engineering history, processes have continually developed and improved safety, especially with rapidly evolving complex aircraft systems.  With more processes to follow, technicians will become more reliant on those processes. The post Hadden-Cave era has led to increased understanding of accountability, thereby diminishing initiative or the application of engineering principles to solve real life engineering problems.  High level policy and accountability rhetoric have cascaded throughout engineering management to engineering technicians, with the warning ‘do not deviate from process’ from fear air safety may be compromised.  This, coupled with the perceived threat of consequence to the individual should compliance be ignored, leads to a culture of process rather than a culture of lateral thought around complex engineering issues. Consequently, naval engineers feel unable to innovate or improvise practical solutions to problems despite engineers understanding the need to maintain air safety.  As a war-fighting organisation which extends to disaster relief operations or damage control at sea, the supervisor/team leader may find themselves without a process and potentially unable to respond with confidence to the situation at hand.  A key attribute of a Petty Officer is initiative; as reliance on process increases and reliance on effective intelligence decreases, are the Royal Navy limiting their future leaders? Attitudes and competence take time to change and develop; there is an increasing risk that the naval engineer of the future fails to think around problems and it is imperative that we encourage and develop initiative in naval aviation engineers.

Abstract

This paper describes the design of fuzzy logic controls in the system of electronic control unit (ECU) of car air conditioner. One obstacle in the car ECU is damage to the air conditioner system. If this happens generally car users change the whole ECU system. But in this paper, the authors form the ECU system which is specifically used for car air conditioner systems. The system is designed using a DS18B20 waterproof sensor to detect the temperature of the car's evaporator. Furthermore, the temperature value is used as a fuzzy logic input consisting of reading the current temperature and the last temperature in adjusting the rotating speed of the DC motor fan or exhausting fan and when the switching magnetic clutch compressor is on. Completion of fuzzy input relations is solved using Mamdani rules and the output of fuzzy logic is solved using the weight average (WA) method. From the test results it was found that the fuzzy logic control applied to the design of the air conditioner system was able to control the speed of the exhausting fan in a smooth and responsive manner.

Abstract

Digital audio watermarking is needed as a protection against online music piracy and copyright issues. This paper describes an audio watermarking combination method where the copyright information is imperceptibly added into the audio signal. The combination of discrete wavelet transform (DWT) and singular value decomposition (SVD) is used to embed and extract the watermark from the audio signal. The copyright information or watermark could be a binary logo or some unique binary patterns. In this paper, a watermarked image is divided into four different capacities of dimension such as 10×10, 30×30, 40×40 and 50×50 pixels. The results of the watermarked image are imperceptibly added into the audio signal and image with 30×30 pixel dimension has the best mean result ranged from 43 to 50 dB. The experiment result also shows that the combination of DWT and SVD is robust against different attacks such as amplify, resampling and invert.

Hasil perancangan diharapkan dapat menjadi acuan spesifikasi keamanan aplikasi layanan informasi di lingkungan instansi pemerintah, khususnya keamanan informasi yang terkait dengan kontrol akses.AbstractLaw Number 14 Year 2008 on Public Information Openness mandates to every government agency to improve management and information service in its environment so as to produce quality information service. Any public information is open and accessible to any user of public information, except for excluded public information because it is strict, limited and confidential. In order to limit information to access only by authorized parties, it is necessary to have an access control mechanism, which processes authentication, authorization, audit and information security in order to secure information through the application of information services.In this research we implement Design Science Research Methodology (DSRM) to design the security specifications based on the access control model. The model implements the process of authentication, authorization, audit and information security that implements cryptography techniques. The design of the security specification using Common Criteria for Information Technology Security Evaluation version 3.1 (REV 5). The design result is expected to become the reference of information security application specification in government institution, especially related to access control.

Authors: Alfiyatin Adyan Nur , Mahmudy Wayan Firdaus , Ananda Candra Fajri , Anggodo Yusuf Priyo
Published: February 2019

Inflasi merupakan salah satu indikator untuk mengukur perkembangan suatu bangsa. Apabila inflasi tidak terkontrol akan memberikan banyak dampak negative terhadap masyarakat disuatu negara. Ada banyak cara untuk mengendalikan inflasi, salah satunya dengan peramalan. Peramalan adalah suatu aktivitas untuk mengetahui kejadian di masa mendatang berdasarkan data masa lalu. Pada penelitian ini menggunakan metode kecerdasan buatan yakni extreme learning machine (ELM). Kelebihan ELM yaitu cepat dalam proses pembelajaran. Berdasarkan penggujian yang dilakukan metode ELM mendapatkan nilai kesalahan sebesar 0.0202008, lebih kecil dibandingkan dengan metode backpropagation sebesar 1.16035821. Hal tersebut membuktikan bahwa metode ELM sangat cocok digunakan untuk peramalan.

Abstract

Inflation is one indicator to measure the development of a nation. If inflation is not controlled will give many negative impacts to the people in a country. There are many ways to control inflation, one with forecasting. Forecasting is an activity to know future events based on past data. In this research using artificial intelligence method is extreme learning machine (ELM). The advantages of ELM are fast in the learning process. Based on ELM testing gets obtained an error value of 0.0202008, smaller than the backpropagation method of 1.16035821. It proves that ELM method is very suitable for forecasting.

 
Nigeria and the African Charter on the Values and Principles of Decentralisation, Local Governance and Local Development: Navigating Content, Context, Issues and Prospects
Authors: Basiru Adeniyi Semiu , Adepoju Adewale Toyin
Published: February 2019

This article examines the major provisions of the 2014 African Charter on the Values and Principles of Decentralisation, Local Governance and Local Development (hereafter the Charter) and the prognosis for the prospects of its actualisation in Nigeria. Specifically, it notes that if this Charter is viewed within the purview of the philosophical principles and values that undergird it, it seems novel. If it is domesticated and internalised by the Nigerian governing elites and their counterparts in other African countries, especially at the federal and local levels, it could be the springboard for ensuring development at grass-roots level. However, based on the evidence they gathered from the review of the country’s development history, the authors argue and submit that the objective of the Charter has a slim prospect of being realised in Nigeria, given the convoluted nature of the Nigerian federal state and the political environment that has sustained it. The article calls for the restructuring of the convoluted Nigerian federal system in order to allow peripheral governments to have more power and resources.
The quality of reported earnings and the monitoring role of the board: Evidence from small and medium companies
Authors: Smith A
Published: February 2019

The purpose of this paper is to investigate whether corporate governance initiatives in South Africa that relate to the monitoring ability of the non-executive directors on the board of small and medium companies have improved earnings quality by adopting conservative accounting practices. The sample construct includes the 2008 â€“ 2011 reporting periods of South African companies listed on the Alternative Exchange (AltX). A reverse regression of earnings on returns was used to examine the market-based attributes of earnings quality, i.e. conservatism and the timeliness of earnings. No evidence was found that the boards of small and medium-sized companies are inclined to adopt conservative accounting practices that will result in the asymmetric timeliness of earnings. There is also no evidence that the quality of reported earnings improved as a result of the monitoring ability of the board with reference to the representation of non-executive directors on the board. The findings can be of interest to investors, managers and regulators as the efficiency of corporate boards and the transparency of financial reporting have implications for all of them.
ABC implementation in the Nelson Mandela Bay Metropole: How far should manufacturing organisations go?
Authors: Reynolds A , Van der Poll H M
Published: February 2019

Activity-based costing (ABC) success factors have been studied in past research, mostly by using commonly known success factors. In this qualitative study, a literature review and interviews were used to establish what factors are responsible for the successful implementation of ABC. The number of semi-structured interviews was limited to 13 ABC adopters in the Nelson Mandela Bay Metropole. The findings suggested that ABC can be enhanced with the use of activity-based budgeting (ABB) and activity-based management (ABM). In addition, the use of ABC in conjunction with capital investment decisions may ensure that correct decisions are made when critical long-term projects are considered. Extensive identification of cost drivers is beneficial to the extent where the product loses its relationship with the overhead cost. It is evident from this research that considering fixed indirect overheads in ABC is not always beneficial for a manufacturing organisation unless there is a clear link to the end-product.
Cost estimation and management over the life cycle of metallurgical research projects
Authors: Odendaal M M , Vermaak F NS , Du Toit E
Published: February 2019

This study investigates whether all expected costs over the life cycle of metallurgical research projects are included in initial, normal and final cost estimates, and whether these costs are managed throughout a projectâ€™s life cycle since there is not enough emphasis on the accurate estimation of costs and their management over the life cycle of metallurgical research projects. The study also determines during which phase of the life cycle of metallurgical research projectsâ€™ costs are normally determined, during which phase most of the costs are incurred, and during which phase costs are managed. Project life cycles, techniques of cost estimation and cost management are examined. 10A survey was used to gather information by means of face-to-face and telephonic interviews, as well as an electronic questionnaire. The total population of entities in South Africa that conduct metallurgical research projects is small, numbering only 12 in all. The ten entities that conducted the largest metallurgical research projects in terms of average size were selected for this study. 11The conclusion drawn from the survey was that all costs over the life cycle of metallurgical research projects are not taken into account in the initial cost estimate of a project. Costs are mainly managed during the growth phase of a project and not during the introduction phase, when 80% of the costs are normally committed. The implication of this is that cost estimates for metallurgical research projects may not be accurate and costs are not necessarily managed properly throughout the life cycle of such projects. This may lead to cost overruns of project budgets, project budgets being depleted before the delivery stage and research sections running at a loss.
Online servicescape dimensions as predictors of website trust in the South African domestic airline industry
Authors: KÃ¼hn S W , Spies H , Petzer D J
Published: February 2019

Increased costs, competition and a dynamic environment have led to South African domestic airlines relying more on their own websites as outlets for airline tickets. Customersâ€™ e-commerce uptake with respect to buying airline tickets online has been slow, attributed mostly to a lack of website trust. A well-designed online service scape has been identified as an important contributor to website trust by several authors, but not yet in this particular context or industry. This study investigates the extent to which three online service scape dimensions predict website trust in the South African domestic airline industry. A quantitative and descriptive research design was followed, and 300 responses were collected through self-administered questionnaires from domestic airline passengers who had purchased an airline e-ticket from a website. A multiple regression analysis indicates that online financial security is the best predictor of website trust, followed by layout and functionality and aesthetic appeal. Consequently, it is recommended that South African domestic airlines that wish to cultivate website trust should focus primarily on enhancing the online financial security of their websites, followed by customising the layout and functionality of their websites, and lastly improving aesthetic appeal by increasing the entertainment value of their websites.
