Retinoblastoma protein represses E2F3 to maintain Sertoli cell quiescence in mouse testis
Authors: Rotgers Emmi , Cisneros-Montalvo Sheyla , Nurmio Mirja , Toppari Jorma
Published: July 2019

Maintenance of the differentiated state and cell cycle exit in adult Sertoli cells depends on tumor suppressor retinoblastoma protein (RB, also known as RB1). We have previously shown that RB interacts with transcription factor E2F3 in the mouse testis. Here, we investigated how E2f3 contributes to adult Sertoli cell proliferation in a mouse model of Sertoli cell-specific knockout of Rb by crossing these mice with an E2f3 knockout mouse line. In the presence of intact RB, E2f3 was redundant in Sertoli cells. However, in the absence of RB, E2f3 is a key driver for cell cycle re-entry and loss of function in adult Sertoli cells. Knockout of E2f3 in Sertoli cells rescued the breakdown of Sertoli cell function associated with Rb loss, prevented proliferation of adult Sertoli cells and restored fertility of the mice. In summary, our results show that RB-mediated repression of E2F3 is critical for the maintenance of cell cycle exit and terminal differentiation in adult mouse Sertoli cells.

The photophysical properties of three luminescent Cu(I) complexes, [Cu(dmp)(xantphos)]+ (Cu-1; dmp = 2,9-dimethyl-1,10-phenanthroline, xantphos = 4,5-bis(diphenylphosphino)-9,9-dimethylxanthene), [Cu2(dmp)2(µ-dppa)2]2+ (Cu-2; dppa = bis(diphenylphosphino)acetylene), and [Cu2(Ph2dmp)2(µ-dppa)2]2+ (Cu-2ph; Ph2dmp = 2,9-dimethyl-4,7-diphenyl-1,10-phenanthroline), were investigated. The luminescence of Cu-1 at room temperature was assigned to the thermally activated delayed fluorescence (TADF) from the singlet metal-to-ligand charge transfer (1MLCT) excited state. However, the emission of Cu-2 and Cu-2ph exhibited lower radiative rate constants than Cu-1 at room temperature, which can be assigned to phosphorescence from the triplet metal-to-ligand charge transfer (3MLCT) excited state at room temperature. In addition, emission of Cu-2 and Cu-2ph at 77 K indicated significant contributions of the 3ππ* excited state. Theoretical calculations suggested that the energy difference between the optimized S1 and T1 states of Cu-1 is relatively smaller than that of Cu-2. As a result, Cu-1 shows TADF and Cu-2 shows phosphorescence.

Published: July 2019

The forms of iron currently available to correct iron deficiency have adverse effects, including infectious diarrhea, increased susceptibility to malaria, inflammation and detrimental changes to the gut microbiome. These adverse effects limit their use such that the growing burden of iron deficiency has not abated in recent decades. Here, we summarize the protocol of the “Safe Iron Study”, the first clinical study examining the safety and efficacy of novel forms of iron in healthy, iron-replete adults. The Safe Iron Study is a double-blind, randomized, placebo-controlled trial conducted in Boston, MA, USA. This study compares ferrous sulfate heptahydrate (FeSO4·H2O) with two novel forms of iron supplements (iron hydroxide adipate tartrate (IHAT) and organic fungal iron metabolite (Aspiron™ Natural Koji Iron)). In Phase I, we will compare each source of iron administrated at a low dose (60 mg Fe/day). We will also determine the effect of FeSO4 co-administrated with a multiple micronutrient powder and weekly administration of FeSO4. The forms of iron found to produce no adverse effects or adverse effects no greater than FeSO4 in Phase I, Phase II will evaluate a higher, i.e., a therapeutic dose (120 mg Fe/day). The primary outcomes of this study include ex vivo malaria (Plasmodium falciparum) infectivity of host erythrocytes, ex vivo bacterial proliferation (of selected species) in presence of host plasma and intestinal inflammation assessed by fecal calprotectin. This study will test the hypotheses that the novel forms of iron, administered at equivalent doses to FeSO4, will produce similar increases in iron status in iron-replete subjects, yet lower increases in ex vivo malaria infectivity, ex vivo bacterial proliferation, gut inflammation. Ultimately, this study seeks to contribute to development of safe and effective forms of supplemental iron to address the global burden of iron deficiency and anemia.

Improving palliative and end-of-life care with machine learning and routine data: a rapid review
Authors: Storick Virginia , O’Herlihy Aoife , Abdelhafeez Sarah , Ahmed Rakesh , May Peter
Published: July 2019

Introduction: Improving end-of-life (EOL) care is a priority worldwide as this population experiences poor outcomes and accounts disproportionately for costs. In clinical practice, physician judgement is the core method of identifying EOL care needs but has important limitations. Machine learning (ML) is a subset of artificial intelligence advancing capacity to identify patterns and make predictions using large datasets.  ML approaches have the potential to improve clinical decision-making and policy design, but there has been no systematic assembly of current evidence.

Methods: We conducted a rapid review, searching systematically seven databases from inception to December 31st, 2018: EMBASE, MEDLINE, Cochrane Library, PsycINFO, WOS, SCOPUS and ECONLIT.  We included peer-reviewed studies that used ML approaches on routine data to improve palliative and EOL care for adults.  Our specified outcomes were survival, quality of life (QoL), place of death, costs, and receipt of high-intensity treatment near end of life.  We did not search grey literature and excluded material that was not a peer-reviewed article.

Results: The database search identified 426 citations. We discarded 162 duplicates and screened 264 unique title/abstracts, of which 22 were forwarded for full text review.  Three papers were included, 18 papers were excluded and one full text was sought but unobtainable.  One paper predicted six-month mortality, one paper predicted 12-month mortality and one paper cross-referenced predicted 12-month mortality with healthcare spending.  ML-informed models outperformed logistic regression in predicting mortality but poor prognosis is a weak driver of costs.  Models using only routine administrative data had limited benefit from ML methods.

Conclusion: While ML can in principle help to identify those at risk of adverse outcomes and inappropriate treatment near EOL, applications to policy and practice are formative.  Future research must not only expand scope to other outcomes and longer timeframes, but also engage with individual preferences and ethical challenges.
General Principles for Formation of Ruled Surfaces. Part 3
Authors: Сальков Николай , Sal'kov Nikolay
Published: July 2019

We continue to consider the formation of ruled surfaces with a single method of their formation. In the first and second parts have been introduced more than forty options for specifying surfaces. These formations with the help of guide lines and surfaces are considered in a new aspect – as formation in science and production of all of ruled surfaces. In this paper, we consider new options for specifying ruled surfaces. Generalized the task for torso surface. If in textbooks on descriptive geometry torso surface is given as 1∞ straight lines, tangent to the spatial line, the proposed version of the are considered three guides: two curves (surface) plus a plane touching to both curves (surfaces). It is shown that three guides are also required to set screw ruled surfaces. The concept of a limit ruled surface is introduced to determine the region of existence of ruled surfaces. The table of the simplest geometrical figures for obtaining congruences is given. A number of examples of congruences obtained by using two guides are given. All these examples once again confirmed the validity of the law of assignment of ruled surfaces using three guides and three geometric conditions characterizing the ratio of the forming line to these three guides. The three geometric conditions are the contact of the forming line to the guide surface and the intersection of the forming line with the guide line. The proposed task of ruled surfaces can be used in the consideration of ruled surfaces in lectures on descriptive geometry and other geometric disciplines.
Analytical Dependences of the Kinematic Forming Primary Surfaces of the Worm Gear
Authors: Рязанов С. , Ryazanov S. , Решетников М. , Reshetnikov M.
Published: July 2019

The run-in method for obtaining the screw surface of a worm is based on the use of the worm gearing principle. In this case, the shaping surface (cutting tool) and the workpiece constitute a gear pair [4; 7]. The use of geometric modeling methods [8; 9] to simulate the process of shaping the working surface is based on the relative movement of intersecting objects in the form of a “workpiece-tool” system. This allows to obtain the necessary geometrical model that accurately reproduces the geometric configuration of the surfaces of the teeth of spatial gears [14; 15], where the producing surface of the tool moves in the selected reference system and its position at an arbitrary time is determined by a certain parameter, the motion parameter. The position of the cutting tool at the beginning and at the end of each pass is calculated using parametric equations, which make it possible to calculate the tool path for accurate processing of spatially complex surfaces [16–19]. In the process of mechanical action of a tool on a solid (workpiece), shaping occurs, which consists in the movement of the tool relative to the workpiece [30; 31]. The use of modern methods of three-dimensional computer graphics allows us to improve and accelerate the process of designing technological operations of tooth profiling, providing the final forms of the surfaces of the teeth in the form of visual and accurate computer-based solid-state models [39; 40]. The method is based on a virtual representation of the process of shaping in the form of intersection of solid-state 3D models of two objects (tools and workpieces), which generally perform a screw relative motion. As a result, the working surfaces of the teeth are formed as the envelopes of the tool producing surface [32–34]. For the formation of fission surfaces, mathematical dependences were obtained, which allow one to describe the mutual motion of a worm, a worm gear and a disk cutter [35–37]. These analytical dependences make it possible to simulate the virtual process of forming the side surfaces of the worm gearing elements [1–3; 5; 6]
Business Analytics for Intermodal Capacity Management
Authors: Gao Long , Shi Jim (Junmin) , Gorman Michael F. , Luo Ting
Published: July 2019

Network operations often suffer from chronic asset imbalance over time and across locations. This paper addresses the issue in the intermodal industry. The problem is mainly driven by myopic policies, environmental uncertainty, and network interdependence. To address the problem, we develop a unified framework that integrates two core operations: container repositioning and load acceptance. The central piece is the scarcity pricing scheme, which internalizes the externalities each acceptance imposes over time and across locations. The scheme plays two crucial roles: to transmit dynamic scarcity information and to incentivize container repositioning. It is most effective when network imbalance and supply risk are high. Exploiting random capacity and heterogeneous lead time, we further refine the load acceptance policy and develop efficient algorithms. We demonstrate that our approach can dynamically reduce network imbalance and improve efficiency. As such, our work provides analytical tools and insights on how to manage network capacity, when the information is dispersed and evolving over time.

Published: July 2019

This paper endeavors to ascertain the prevailing classroom management styles of instructors as well as the prevailing instructor-student relationship in a Philippine higher education institution. It   employed mixed methods of quantitative and qualitative methods of research to investigate the line of inquiry. A total of thirty faculty members and three-hundred students sampled from the population were the sources of data for the quantitative component of the study while eighteen students were selected as informants for the FGD to gather qualitative data. Findings showed that a great deal of authoritative classroom management style is being adhered by instructors while the students manifested a moderate level of connectedness and anxiety towards the classroom management styles of their instructors. Variables such as civil status, years of teaching experience, and level of educational attainment spelled differences on the classroom management styles instructors. It was uncovered that the different classroom management styles of instructors were attached with positive and negative labels and typifications. Implications of this study will serve as a reference to better prepare classroom managers of 21st-century college classrooms.

Authors: Habte Niguse Mengesha , Melku Abulie Takele , Alemayehu Mulusew Teshome
Published: July 2019

Background
Adolescents is the transition from childhood to adulthood .Which is a time of opportunity, but also one of risk. In Ethiopia, sexual and reproductive health problems of adolescents are increasing from time to time related to many parents not feeling happy to discuss sexual matters in addition to early sexual commencement among adolescents.

Objective
This study was intended to assess parent-adolescent communication on sexual and reproductive health matters and associated factors among secondary and preparatory school students in Robe Town, Bale Zone, South East Ethiopia, 2017.

Methods
Institution based cross sectional study was conducted among 394 secondary and preparatory school students in Robe town from April 10-25, 2017. Simple random sampling technique was used. Data was obtained through the use of a self administered questionnaire and supplemented by focus group discussion with parents. Data was entered using Epi Data 3.1 and analyzed by SPSS 20. Descriptive statistics and logistic regression analyses were done. Data quality was assured through careful questionnaire design, pretest and training.

Results
One hundred eighty six (47%) of the study participants had discussed at least two SRH issues with their parents. Grade eleven students were about nearly five times more likely discussed on sexual and reproductive matters with their parent compared with grade nine students (AOR: 4.88, 95% CI: 1.76, 13.54). Those living with relatives were 3.13 times less likely discussed as compared to those students are living with both parents (AOR: 0.32, 95%CI: (0.12, 0.80) and the odds of discussion on SRH matters is 2 times higher among females compared with their counterpart (AOR=2.02, 95% CI: 1.25, 3.26).

Conclusions
Communication on sexual and reproductive health matters between adolescent and parent was low. Majority of student preferred to discuss with their peers than parent. Being ashamed, parents lack of communication skill and parent knowledge on SRH issues were the major reasons mentioned by the students for not discussing about SRH matters with their parents. Therefore; comprehensive family life education needs to be initiated for the students and parents. Sexual information exchange between peers needs to be strengthened.

Authors: Bureš Marek , Martirosov Sergo , Polcar Jiří
Published: July 2019

The paper is focused on point cloud data processing obtained by 3D laser scanning. The scanning devices are at a very advanced level and after reaching their possible maximum scanning speeds, manufacturers are now more focused on a minimization of the devices. However, there is still a lack of software solutions for a simple and successful model creation from point cloud data or data evaluation. This paper briefly describes the laser scanning principle and the process of production floor layout capturing. Furthermore, a newly developed algorithm for an extraction of specific areas of point cloud is introduced. The algorithm was tested and compared with other solutions for a production layout development. After testing, the standalone software application called CloudSlicer™ was programed and the user interface is also presented.
NON-DESTRUCTIVE INSPECTION BY INFRARED THERMOGRAPHY OF RESISTANCE SPOT WELDS USED IN AUTOMOTIVE INDUSTRY
Authors: Forejtová Lucie , Zavadil Tomáš , Kolařík Ladislav , Kolaříková Marie , Sova Jan , Vávra Petr
Published: July 2019

Resistance spot welding (RSW) is one of the main joining technologies of thin sheets in the automotive industry. Key factors affecting the strength of the RSW joint are the nugget diameter, asymmetry, expulsions, intended surfaces, and the presence of cracks. Despite its broad use, the RSW joint quality verification is limited only to destructive testing and a limited number of non-destructive testing (NDT) methods. Most of the testing is done destructively by sampling, which assesses only systematic defects. Ultrasonic Testing (UT) is the most used NDT method to detect non-systematic defects in the RSW joints, however the probability of the defect detection of conventional testing techniques is not fully satisfactory. Other approaches were invented to deal with this situation. The article uses the currently most used NDT approach of the UT testing as a benchmark to evaluate the ability of thermographic testing to detect defective welds of the resistance spot welding in an on-line mode. The article demonstrates that the infrared thermography may find systematic process errors that are not detectable by other NDT methods by an analysis of different temperature drops measured after a constant delay time caused by different cooling dynamics of satisfactory and non-satisfactory weld joints.

Published: July 2019

O mito corresponde à narração de um tempo passado original, precursor de todos os tempos, nos quais poderemos encontrar os modelos e exemplos que determinam e dão sentido à vida. Tendo acompanhado o Homem desde os primórdios da humanidade, o mito encontra-se enraizado nos comportamentos humanos, explicando simbolicamente factos humanos e naturais. No seguimento de um trabalho anterior, no qual procuramos compreender ontologicamente quer a função social do mito, quer o estabelecimento da mitologia como ciência, pretendemos, desta feita, compreender a importância social e simbólica do mito, desde que se estabeleceu como ciência, até à atualidade.

Published: July 2019

Exact string matching is one of the critical issues in the field of computer science. This study proposed a hybrid string matching algorithm called E- AbdulRazzaq. This algorithm used the best properties of two original algorithms; AbdulRazzaq and Berry-Ravindran Algorithms. The proposed algorithm showed an efficient performance in the number of attempts and number of character comparison when compared the original and recent to the standard algorithms. The proposed algorithm was applied in several types of databases, which are DNA sequences, Protein sequences, XML structures, Pitch characters, English texts, and Source codes. The Pitch database was the best match for E-AbdulRazzaq with the number of attempts involving long and short patterns, while the DNA database was the worst match. No data is specified as the best or worst with the E-AbdulRazzaq algorithm in terms of the character comparisons. The E-AbdulRazzaq algorithms ranked first in most databases when using short and long patterns, in terms of number of attempts and character comparisons.

Published: July 2019

This research compares the recognition performance between pre-trained models, GoogLeNet and AlexNet, with basic Convolution Neural Network (CNN) for leaf recognition. Lately, CNN has gained a lot of interest in image processing applications. Numerous pre-trained models have been introduced and the most popular pre-trained models are GoogLeNet and AlexNet. Each model has its own layers of convolution and computational complexity. A great success has been achieved using these classification models in computer vision and this research investigates their performances for leaf recognition using MalayaKew (MK), an open access leaf dataset. GoogLeNet achieves a perfect 100% accuracy, outperforms both AlexNet and basic CNN. On the other hand, the processing time for GoogLeNet is longer compared to the other models due to the high number of layers in its architecture.

Published: July 2019

The impact of moral, psychological and legal aspects of the evaluation of evidence by the officials conducting the criminal proceedings on the attitude of society to its results is considered in this article. The comparative legal, formal-legal, and logical methods of study are used herein to prove that the evaluation of evidence as a mental activity cannot be controlled externally. At the same time, a free assessment of evidence is the only way to establish properly the circumstances in a criminal case. At the same time, the moral and psychological aspects of the evaluation of evidence are inherent characteristics of human thought and do not interfere with the establishment of truth. The conclusion is substantiated that it is possible to provide an objective evaluation of evidence only by the external criterion – the moral requirements to the selection of judges, prosecutors, investigators and their upbringing, checked by the society.

Published: July 2019

The article reveals one of the main paradigms for the agricultural land use development. Adaptation is not only a necessity, but a means to improve sustainability and efficiency in the use of agricultural land. The conditions of external systems that determine the direction and magnitude of adaptation options for agricultural land use have also been shown. The features of adaptation of the basic land use elements have been described: land plots, legal status, engineering equipment of the territory, land use system, and land use maintenance system. The article provides a more detailed overview of the adaptation of the main land use system element (agriculture), which will ensure the adaptation of crops and their varieties to the features of soils and terrain; the adaptation of cultivation technologies to the soil and terrain, the features of the territory; the adaptation of fertilizer systems to soils and crops and their varieties; the adaptation of cultivation technologies to the actual technical equipment; the adaptation of the farming system to the actual financial condition; and the adaptation of the farming system to the natural conditions of the year. A monographic description of the land use adaptation experiment by Chistoe, LLC in the Tyukalinsky District of the Omsk Region has been produced. Mutual adaptation of both land management and its technical and technological components has been proposed for the agricultural land development project. It is expected that this will minimize the required financial costs by adapting land properties, reducing types of machines and the technologies used.

A novel approach for securing images using visual cryptographic scheme
Authors: B R Pushpa , Kumar B J Santhosh
Published: July 2019

Most applications require exchanging of information over insecure networks. The important issue concerned with respect to the images is to provide confidentiality and integrity. An efficient technique is proposed in order to provide protection to significant images through the digi-tal encryption scheme. Encryption before transmission is necessary for these images such that it makes sure that unauthorized person fails to access to any information. An efficient visual cryptographic approach is proposed for securing images by providing encryption during transferring an images or storing them. The technique proposed ensures that the images are inaccessible by unauthorized persons and also certifies confidentiality. In this proposed method to enhance security during data transmission across the network first the original image gets divided into multiple shares using logic operations and hence encryption technique is employed to these shares to maintain security. The binding of encryption and shares together called as encrypted shares are delivered and at the receiver side the reverse operation is carried out to retrieve back the original image. In the decryption process the decrypted share are layered to extract the actual image and if any shares are lost it is difficult to retrieve the information. The experimental result of the proposed method validates that the method will efficiently encrypt the image with a reduced amount of time without increasing the pixel size.
Web application to measure level of addictive game
Authors: Latubessy Anastasya , Jazuli Ahmad
Published: July 2019

Game becomes very popular within all ages. The intensity of someone playing games can influence the behavior of that person. World Health Organization (WHO) is classifying gaming disorder as an addictive behavior disorder. According to psychologists, there are six types of game addiction behavior, such as, Salience, Euphoria, Conflict, Tolerance, Withdrawal, and the last is Relapse and Reinstatement. A person is said to be addicted to the game if it meets at least three of the six types of behavior that exist. The six types of game addiction behavior then modeled using backward chaining algorithm. After that, the model was implemented into the system. Thus this research re-sult a web application to identify game addiction. Now we can measure how many people are affected using this web application.
Neural Processing of Other-Race Faces as a Function of Racial Familiarity: A P300 Study
Authors: Yan Shan Tai , Reza Faruque , Begum Tahamina , Yusoff Nasir
Published: July 2019

Background: The other-race categorisation advantage (ORCA) is a well-established phenomenon, whereby other-race faces are categorised faster than own race faces. Objectives: This study investigated whether extraverts would demonstrate an ORCA-like effect toward unfamiliar other-race faces and familiar other-race faces in a modified oddball and choice reaction paradigm.  Methods: This event-related potential (ERP) study employed a repeated measures experimental design with one independent variable (racial familiarity) and three levels (familiar other-race/Malay faces, unfamiliar other-race/African faces, control group/furniture photos). In the oddball task, African faces and Malay faces were the target stimuli and furniture photos were the standard stimuli. Electroencephalography data (EEG) was collected during the oddball task, from which ERP components were derived. Results: The reaction time (RT) for African and Malay faces were not significantly different.  Significant effect of racial familiarity on P300 latencies at all electrode sites was not observed.  However, there was a significant effect of racial familiarity on P300 amplitudes at midline electrodes (Cz).  It was also observed that the P300 amplitude was larger for African faces than Malay faces at midline electrodes (Cz). Conclusion: An ORCA-like effect was not found in categorisation tasks involving faces from a familiar and an unfamiliar other-race, but a larger P300 amplitude was evoked by African faces. This dissociation between RT and P300 amplitude provided important theoretical implications with regard to models associated with ORCA. Specifically, the current findings lent support to the social cognition model and the Categorisation-Individuation Model (CIM).
Neurofeedback for Anxiety Symptoms Among University Students
Authors: Adela Mutang Jasmine , Bee Seok Chua , Iqbal Hashmi Shazia
Published: July 2019

Anxiety is a common, universal human emotion, but excessive feelings of anxiety can negatively affect one’s life satisfaction and quality of life. Psychotherapy and medication are the most common forms of intervention for anxiety disorders. In a recent development, researchers suggested that neurofeedback training (NFT) has the potential to reduce symptoms of anxiety, claiming to be less invasive while carrying fewer side effects compared to medication. Therefore, this preliminary study sought to assess whether neurofeedback training is a viable method to improve symptoms of anxiety in the nonclinical sample. Participants were randomly assigned to two groups (neurofeedback training group or a control group). Anxiety symptoms were assessed using the Depression, Anxiety and Stress Scale (DASS-21), the Beck Anxiety Inventory (BAI), and the State-Trait Anxiety Inventory (STAI). The findings showed an overall improvement in all of the psychological measurements in the neurofeedback group hence provide additional evidence to the field of neurotherapy that neurofeedback training is a viable option to improve anxiety symptoms among university students.

Unfortunately, several contaminants could present in groundwater make it unsafe for domestic used and drinking water purpose. Therefore, groundwater should be treated to acceptable level before it can be consumed for further use. The aim of this study was to improve the groundwater quality in terms of physical parameters and bring it within the acceptable level using simple and economical aeration and filtration methods. Gravel, ceramic and charcoal were used as filter materials. The removal efficiency was determined from the calculated percentage removal of the tested parameters. Based on the results, groundwater showed improvement in its physical quality with percentage removal of turbidity, BOD and COD at 92%, 73% and 79%, respectively. Parameter pH also showed good improvement from slightly acidic to neutral range. However, TDS gave different results. With the exception of TDS, all parameters comply with the Malaysia’s standard of raw and drinking water quality set by Ministry of Health.

Nonconductive ceramic materials are used in many engineering applications such as car brake, turbine blade, and hip-bone replacement because of its high dimensional accuracy, corrosion and wear resistant, and biocompatibility. These materials are usually processed with diamond grinding and limited laser applications such as cutting, drilling and scribing. Specific shapes and profiles are still difficult and costly to machine using these processes. Electrical discharge machining (EDM), extensively used for various shapes and profiles on conductive materials having minimum electrical conductivity of 0.10 S.cm-1. It is not directly applicable on nonconductive ceramic materials due to its very low electrical conductivity (<10-10 S.cm-1). However, recently EDM is used on nonconductive materials with the aid of assisting electrode to initiate the spark between conductive tool electrode and nonconductive workpiece. The available material removal models of EDM are based on single spark erosion with uniform melting and vaporization of workpiece materials. However, in EDM of nonconductive ceramics, material removal is not uniform because of random spalling due to alternating thermal stress. In addition, it is difficult to create single spark erosion on a nonconductive ceramic workpiece as initial sparks are occurred between tool electrode and assisting electrode attached to workpiece. This paper presents the empirical factor for the estimation of spalling along with melting and vaporization through experimental study. Model of material removal rate as a function of capacitance and voltage are developed in micromachining of nonconductive zirconium oxide (ZrO2) using (R-C) pulse type micro-EDM. The single spark erosion volume is derived from the fundamental principle of melting and vaporization. An empirical correction factor is introduced to compensate random spalling and multi-spark erosion effect.

Lack of safety participation in Occupational Safety, Health and Environment Management System (OSHMS) has exposed employees to high risk of work hazards resulting in high occupational accidents. This does not only affect employee’s morale towards work, but employer also needs to bear the cost of recovery and its effect to its reputation. This study was carried out to determine the relationship of safety capital (management safety commitment, safety training, extrinsic reward, intrinsic reward, employee involvement, safety communication and safety advice) and safety participation in OSHMS using the resource-based view (RBV) and knowledge-based view (KBV) theories. A total of 100 responses were collected from Malaysian manufacturing firms certified with OSHA18001. Data were analysed using the Smart Partial Least Square (SmartPLS). Results showed that safety training, extrinsic reward and employee involvement directly affect safety participation in OSHMS but not Management Safety Commitment, Intrinsic Reward and Safety Communication. However, Management Safety Commitment and Safety Communication indirectly affect safety participation in OSHMS moderated by high safety advice. As a managerial implication, this research showed that the role played by the safety officers represented by the safety advice is important in enhancing the safety practices and commitment in place to result in a successful safety participation in OSHMS.
A Review of Key Factors That Affect University Building Maintenance Costs

As Malaysia continues to focus its efforts on becoming an education hub, universities are vital places where learning processes, teaching and research activities are conducted. A university is a factor of production in producing graduates, and the university buildings are considered to be assets and resources. Hence, to prolong a university building lifecycle to ensure all university activities continue performing at an optimum level, building maintenance management is vital. Despite the fact that several previous studies have been conducted in this area, there continues to be maintenance issues surrounding university buildings. The maintenance of university buildings has always been viewed as an insignificant activity. Therefore, the objective of this paper was to critically review key factors that affected maintenance costs of university buildings, and consequently propose different approaches to resolve this issue. The present paper reviewed related literature from previous studies and publications. As a result of the comprehensive review, it was identified that key factors that affected university building maintenance costs were fund allocations allocated by university management teams for maintenance departments, user behaviours, environmental factors, university design complexities and the quality of components and materials of university buildings. Each factor identified was critically examined and addressed to ensure that university buildings would be well-maintained.

Mahalanobis Taguchi System is an analytical tool involving classification, clustering as well as prediction techniques. T-Method which is part of it is a multivariate analysis technique designed mainly for prediction and optimization purposes. The good things about T-Method is that prediction is always possible even with limited sample size. In applying T-Method, the analyst is advised to clearly understand the trend and states of the data population since this method is good in dealing with limited sample size data but for higher samples or extremely high samples data it might have more things to ponder. T-Method is not being mentioned robust to the effect of outliers within it, so dealing with high sample data will put the prediction accuracy at risk. By incorporating outliers in overall data analysis, it may contribute to a non-normality state beside the entire classical methods breakdown. Considering the risk towards lower prediction accuracy, it is important to consider the risk of lower accuracy for the individual estimates so that the overall prediction accuracy will be increased. Dealing with that intention, there exist several robust parameters estimates such as M-estimator, that able to give good results even with the data contain or may not contain outliers in it. Generalized inverse regression estimator (GIR) also been used in this research as well as Ordinary Lease Square Method (OLS) as part of comparison study. Embedding these methods into T-Method individual estimates conditionally helps in enhancing the   accuracy of the T-Method while analyzing the robustness of T-method itself.  However, from the 3 main case studies been used within this analysis, it shows that T-Method contributed to a better and acceptable performance with error percentages range 2.5% ~ 22.8% between all cases compared to other methods. M-estimator is proved to be sensitive with data consist of leverage point in x-axis as well as data with limited sample size.   Referring to these 3 case studies only, it can be concluded that robust M-estimator is not feasible to be applied into T-Method as of now. Further enhance analysis is needed to encounter issues such as Airfoil noise case study data which T -method contributed to highest error% prediction.  Hence further analysis need to be done for better result review.

A report published on 25 April 2016 stated that OSHA has issued 14 serious violations after an investigation conducted in a variety of industries including manufacturing, water treatment and oil and gas that violated OSHA's Process Safety Management (PSM) standard. One of the violations is related to the 29 CFR 1910.119(c)(2) which is employers did not consult with employees and their representatives on the conduct and development of the OSHA’s PSM elements which are process safety information (PSI), process hazard analyses (PHA), training (TNG), mechanical integrity (MI), management of change (MOC), pre-start up safety review (PSSR), contractors (CON), incident investigations (II), emergency planning and response (EPR), compliance audit (CA) and trade secret (TS). 29 CFR1910.119(c)(2) is one of the requirements in the OSHA’s PSM employee participation element. However, companies are still struggling to comply with this regulation due to unclear coverage and the implementation method for achieving compliance. Thus, this paper presents a framework and work-aid tool developed based on OSHA’s PSM 29 CFR 1910.119(c) which are helpful to the industries as they provide structured technique to plan and implement an employee's participation management system to achieve compliance in implementing the OSHA PSM employee participation element.
