Important reasons and effort to build school work and committee harmony
The purpose of research is important to know the reasons and the efforts to build school work and school committee harmony. Pamekasan research sites in East Java province with research subjects principals and elementary school committee chairman as many as 44 people from 28 primary schools. The research method uses a quantitative approach using descriptive analysis and technical analysis of Pearson product moment correlation. The results show how many reasons there are important and efforts to build school work and school committee harmony. There is a relationship between the importance and the efforts to build school work and school committee harmony with a correlation coefficient of 0.986.
Keywords: reason, effort, harmony, school work and committees

Replenishment cost of a storage system modelled through a defective renewal equation
A storage system where a k units stock is replaced instantaneously, when required, is presented in this work. It is also supposed a Poisson demand. It is proved that the storage system replenishment cost expected present value function fulfills a defective renewal equation, being proposed for it an asymptotic expression.

Antimicrobial and anthelmintic activity of Elecusine indica
Antimicrobial activity of Elusine indica was carried out using Agar well diffusion method on selected pathogens usually associated with diarrhea or other stomach problems such as Shigella dysenteriae Escherichia coli, Salmonella typhi, Staphylococcus aureus, Streptococcus facealis and Lactobacillus lactis. The aqueous extract was the most susceptible while the ethanol extract was the least susceptible to these microorganisms. The observed antimicrobial activity is concentration dependent. The work also shows that the plant has marked anthelmintic activity against Strongyloides stercoralis. The work therefore gives credence to the use of Eleusine indica against diarrhea and worm infections.

The influence of snakehead (Channa striata) extract treatment to the MDA level in pancreas of hyperglycemic rat (Rattus novergicus)
The influence of snakehead (Channa striata) extract (SHE) on the MDA level in hyperglycemic rat (Rattus novergicus) had investigated. Injection of alloxan monohydrate was conducted to induced the hyperglycemic prior to treatment with SHE by oral methods for two weeks. The oxidant capacity of SHE in pancreas were evaluated based on the level of Malondialdehide (MDA). Pancreatic MDA concentration in the group of hyperglycemic rat that was not treated by SHE was in level of 93.96 nmol/ml which significantly higher (p<0.05) than groups of hyperglycemic rat that were treated by SHE in the highest and median dosage i.e. MDA=23.98 nmol/ml and 33.43 nmol/ml, respectively. The lower MDA concentration in the SHE treatment group indicates that SHE therapy can improve the antioxidant capacity resulting the lower levels of free radicals or oxidative stress in pancreas.

Literature of socialist realism as a reflection of changes and flexibility in communist society in Albania
In this paper I will attempt to analyze how the literature of Socialist Realism reflected the changes and flexibility of the Albanian society during the period of Communism. And these changes and flexibility projected in philosophy and ideology in power significantly emerge in the literature of that season of time within the frame of gender roles also under the perspective of literature of Socialist Realism. In this venue, the prototypes developed by the literature of Socialist realism and scenarios conceived, as their contextual adjustment, evidenced the changes and flexibility in gender roles dressing up the characters of both genders with equal responsibilities and loaded them with importance and significance.

Application of lean six sigma methodology on construction field - Part 1: Define phase
This aim of this study was to apply Lean Six Sigma methodology through the famous DMAIC (Define, Measure, Analyze, Improve and Control) approach to improve the efficiency of construction activities. Lean manufacturing concept is based on increasing the efficiency by eliminating non-added value (waste) activities. Six Sigma is a statistically-based process improvement methodology that aims to reduce defects to a rate of 3.4 defects per million defect opportunities. Lean (with its roots in the Toyota Production System) and Six Sigma (with its roots in the Motorola Quality System) is essentially the combination of two strategies, cultures, methodologies and tool sets with overlapping themes but are also uniquely different value propositions. Six Sigma is limited to process quality tools and does not have the process speed tools. Similarly, Lean does not possess the tools to bring a process under statistical control, nor does it define a sustaining infrastructure or emphasize customer focus as does Six Sigma. Thus, achieving the goals of enterprise requires both Lean and Six Sigma.

Sleep deprivation is a problematic issue that exists throughout the entire human population and affects all age groups across the millennium. Lack of sleep can cause serious health issues, academic problems, and mistakes in the work place. It is imperative that individuals get enough sleep to be able to function mentally and physically throughout the day. Sleep is an essential part of human nature and is crucial for the brain and body systems to rest and regenerate. This enables college students, nurses, health care students, physicians, and surgeons to function safely in their work environment, at school, or at home. This paper will explore sleep deprivation among college students, nurses, residents/interns, physicians, and surgeons. Sleep deprivation will also be explored as to how it relates to automobile accidents, medical problems, mistakes in the work place, medication errors, and poor student functioning in the classroom setting due to lack of sleep.
Keywords: sleep deprivation, cognitive, accidents, health problems, college students, nurses, surgeons, junior hospital doctors, physicians

Decentralized Wastewater Treatment System (DEWATS) as a modern approach for wastewater management in Egypt, review
The main aim of this study was to present a review about Decentralized Wastewater Treatment Systems (DEWATS) as a tool for wastewater treatment that could be applied in Egypt. In Egypt, from the south of Giza to Aswan (Upper Egypt), people live very near to the shores of the river Nile. The cities and big villages lie on River Nile and bounded with the river banks at one side and with mountains and desert from the other side. The great challenge is to save lands for domestic life and cultivation. The limited area and the finite available land between the Nile and the Mountain present difficulty for expansion and industrial and social development. Decentralized wastewater treatment systems (DEWATS) includes only such systems which are considered suitable for decentralized applications and dissemination in the case that qualified maintenance and operation cannot be expected.

Production of nano emulsion terpolymers binders for textile application
Micro emulsion polymer with a high content of ethyl acrylate soft monomer was the most used binder for textile pigment printing application. This work aimed to improve the physical and mechanical properties of pigment printing application using series of terpolymer prepared by polymerization of ethyl acrylate with methyl methacrylate and 2-ethyl hexyl acrylate at different concentration ratios of methyl methacrylate (2.5%, 5%, 7.5%, and 10%) respectively of the total monomer concentrations. The prepared terpolymers were characterized using solid content, molecular weight, coagulum, viscosity, drying time, UV, MFFT and TEM. The mechanical properties of the prepared polymers would be also examined. It was found that methyl methacrylate / 2-ethyl hexyl acrylate/ethyl acrylate terpolymer of ratio (10:10:80) respectively showed the best heat fastness, mechanical fastness, soft handling and high color yield of pigment printed textile.
