Learning aquatic skills is an important component of developing physical literacy in children. Aquatic skills such as floating, swimming and safe entry/exit promote engagement in different water environments and may help preserve lives in an emergency. This scoping review was conducted to evaluate the influence of task constraints (i.e., equipment) and environmental constraints (i.e., physical and social) on how children learn foundational aquatic skills. In developed countries, children are typically taught in swimming pools under direct supervision. It is also not uncommon to see children and infants learning to swim with assistive equipment (e.g., buoyancy aids). However, perhaps surprisingly, the evidence on how and where children learn aquatic skills does not uniformly promote such practices. For example, the use of flotation devices has not been proven to aid skill learning. Some researchers have advocated that children should learn aquatic skills whilst wearing outdoor clothing. One benefit of children wearing clothing is an increased capacity to practice in colder water (such as the ocean, rivers, or lakes). Overall, whilst practitioners often use equipment for various reasons it seems that not all equipment is equally useful in promoting the acquisition of aquatic skills. In less developed countries, with limited access to swimming pools and fewer resources for private instruction, a range of different open water aquatic environments and practices, such as swimming in temporarily flooded areas, have been reported. Such strategies are in urgent demand of further research given that drowning rates in less developed countries around the world exceed those in developed nations. It can be argued that learning in pools does not afford the opportunities to develop the whole range of adaptive skills that may be required in different open water environments such as navigating currents and waves, floating whilst clothed, or making life-saving decisions. Consequently, a shift toward teaching in open water environments has occurred in several countries. This review provides an evidence-base upon which practitioners can design more effective aquatic education programs for children.

The reproductive health of adolescents is of growing concern all over the world. At the global level, many young people get involved in sexual activities and risk sexually transmitted infections (STIs), including HIV or involvement in unintended pregnancy. Young people every where reach puberty earlier and marry later than in the past. As a result, youth are sexually mature for a longer period of time prior marriage. Adolescent pregnancy and childbearing is a major concern and is associated with a range of outcomes detrimental to teen’s health, including complications of pregnancy, illegal and unsafe abortions and death, especially in less developed nations. Fifteen million women age 15-19, give birth every year, 13 million belonging to less developed countries. Over all, 33 percent women from less developed countries give birth before the age of 20 -varying from 8 percent in East Asia to 55 percent in West Africa- (UNFPA; 2000). Adolescent girls in many South Asian settings are unlikely to have much exposure or physical access to outside world. Few services cater to their needs for health care, nutrition, vocational skills, economic opportunities or information. Sizeable proportions of women in south Asia marry well before 18, and early pregnancy further exacerbates their poor reproductive health. This paper examines the knowledge and attitude of female adolescence aged 15-19 years about their reproductive health in Lower Hunza, Northern Areas of Pakistan. First part of this paper comprises introduction of adolescence and reproductive health, its worldwide and Pakistani situation. The second part of the paper consists of hypotheses and key concepts of the study and the third comprises methodology and statistical analysis of the hypotheses. The last section consists of conclusions and recommendation for the improvement of knowledge and awareness programmes for female adolescents as they are more vulnerable than male.

The developed countries are consuming more amount of energy in all forms including electricity continuously with advanced technologies.  Developing  nation’s  energy usage trend rises quickly but very less in comparison with their population and  their  method of generating power is not  seems  to  be  as  advanced  as  developed  nations. The   objective   function   of   this   linear   programming model is to maximize the average efficiency of power generation inIndia for 2020 by giving preference to energy efficient technologies. This model is subjected to various constraints like potential, demand, running cost and Hydrogen / Carbon ratio, isolated load, emission and already installed capacities. Tora package is used to solve this linear program. Coal,  Gas,  Hydro  and  Nuclear  sources can are  supply around 87 %  of  power  requirement .  It’s concluded that we can produce power  at  overall  efficiency  of  37%  while  meeting  a  huge demand  of  13,00,000  GWh  of  electricity.  The objective function shows the scenario of highaverage efficiency with presence of 9% renewables. Maximum value   is   restricted   by   low   renewable   source’s efficiencies, emission constraints on fossil fuels and cost restriction on some of efficient technologies. This    model    shows    that    maximum    18%    of    total requirement   can   be   met   by   renewable itself which reduces average efficiency to 35.8%.   Improving technologies  of  renewable  sources  and  necessary  capacity addition  to  them in  regular  interval  will  enhance  their  role and existence against fossil fuels in future. The work involves conceptualizing, modeling, gathering information for data’s to be used in model for problem solving and presenting different scenarios for same objective.

The report by the UNCTAD Secretariat, submitted to the third session of the United Nations Conference on Trade and Development held in Santiago (Chile) in April 1972, deals with the restrictive business practices of the multinational corporations with special reference to the export interests of the developing countries. Since the world war, there has been a tremendous growth in the size and activities of many international firms. They have grown from the national corporation to the multidivisional corporation and now to the multinational corporation. With each step they acquired greater financial power, better technology and know-how and more complex administrative structures. They have subsidiaries and branches all over the world. In the course of the sixties they became one of the dominant factors in determining the pattern of world trade. At the same time, their increasingly restrictive business practices, which tended to adversely affect world trade and the export interest of less developed countries, attracted the attention of the governments both in developed and less developed countries and serious concern was shown at the international level. It is against this background that the UNCTAD undertook the study on the question of restrictive business practices.

From last few years, the pervasiveness of diabetes mellitus (DM), in Saudi Arabia, is growing at a frightening rate. Overall, one-fourth of the adult population is affected by DM, which is further predicted to rise to more than double by the year 2030. The most alarming is possibly the escalation propensity of diabetes, in recent years, where a nearly ten-fold increase has been witnessed over the past thirty years in Saudi Arabia. However, the number of research arbitrations on the prevalence and incidence of DM is woefully inadequate, as compared to developed countries. Apart from this, most of the existing research data carried out in Saudi Arabia is cross-sectional, with small sample sizes, which most often involve only certain parts of the country. Consequently, the present scenario demands more multidimensional and multisectoral research to strengthen the evidence base and to accumulate greater knowledge as a basis for measures and programmes to confront diabetes and its complications. Thus, the present report makes an attempt to depict the current trend of diabetes as well as intends to put forward essential measures for controlling diabetes in Saudi Arabia.
