Abstract: Studio-based learning is a shared learning environment in which ambiguous problems are addressed. This paper primarily focused on the lightings at the Universiti Kebangsaan Malaysia (UKM)’s architecture studio and to find out whether it had achieved the Indoor Environmental Quality (IEQ). A good design, involving a space in a building, requires sufficient daylight in order to perform a task. This can be achieved by providing enough means to let in diffused light from the sky, yet keeping out direct light from the sun to prevent heat gain and glare. The purpose of this research was to identify the importance of the IEQ in creating conducive studio-based learning environment. The IEQ is crucial for a learning institution since indoor environment factors can actually affect human comfort, health and productivity. Lighting is most important to students as high-quality lighting will improve students’ moods, behavior, concentration, and consequently, their learning. However, the effectiveness of learning in a studio cannot be fully achieved if the IEQ is being overlooked. Presently, artificial lights are being used most of the time in the UKM architecture studios in order to optimize students’ vision and comfort. Using an equipment, named LM-8100, and supported by a questionnaire survey to gauge the lighting comfort level from the students’ perspective, a lighting reading was taken for a duration of 10-hours for three days in the UKM third year architecture studio. The finding showed that the lighting setting is not within the range of the Malaysian Code of Practice on Indoor Air Quality (IAQ). However, the students have perceived it as normal and thus, the situation does not hinder them to stay long inside their studio. This situation will affect the students’ ability to perceive visual stimuli in the short-term and health, in terms of students' vision, in the long run.

Abstract: This paper investigates the impact of anthropogenic heat on formation of urban heat island (UHI) and also determines which factors can directly affect energy use in the city. It explores literally the conceptual framework of confliction between anthropogenic heat and urban structure, which produced UHI intensity and affected energy consumption balance. It then discusses how these two factors can be affected and gives implication to the city and then focuses on whether actions should be taken for balancing adaptation and mitigation of UHI effects. It will be concluded by making the three important strategies to minimise the impact of UHI on energy consumption: landscaping, using albedo materials on external surfaces of buildings and urban areas, and promoting natural ventilation. 1. Introduction The urban built environment itself is related to global changes in the increase of urban temperatures, the rate of energy consumption, the increased use of raw materials, pollution, and the production of waste, conversion of agricultural to developed land, loss of biodiversity, and water shortages [1]. It is clear that buildings not designed for high climatic quality use more energy for air conditioning and more electricity for lighting. Moreover, discomfort and inconvenience to the urban population due to high temperatures, wind tunnel effects in streets, and unusual wind turbulence due to the incorrect use of energy. With the concentration of anthropogenic activities into urban areas, a climatic environmental problem, the “urban heat island” (UHI), has emerged. A UHI is a climatic phenomenon in which urban areas have higher air temperature than their rural surroundings as a result of anthropogenic modifications of land surfaces, significant energy use, and its consequent generation of waste heat. Thus, this proves to be an unsustainable factor that leads to excessive energy use for cooling and places the urban population at greater risk of increased morbidity and mortality. According to the above perspective and considering that rapid and huge population growth is expected in the near future, it becomes increasingly important to apply UHI mitigation strategies in order to reduce energy consumption and improve the quality of life with focusing on energy consumption. Thus, this paper investigates the anthropogenic heat factors that produce the UHI and result in the use of significantly increased use of energy. Then, according to the Oke’s energy balance conceptual model, all of the energy which is absorbed by the surface through radiation or from anthropogenic

Abstract: E-learning is one approached in the learning style of the courses for UKM Bachelor of Architecture program, namely Research Methodology. The e-learning is not a new paradigm in today’s teaching and learning process, thus, using the platform of UKM portal system, SPIN we start to adapt this approach and make it as practical to the students. This study is highlighting 4 learning approaches that might be preferred by the students in encouraging them to use SPIN, namely class contact hours of every 2 weeks time, 1 h lecture, white board style and let the student talk and do. The findings from the study reveals, in principal the students agree to use the SPIN, with the lecturer observing the usage of the system in SPIN via progress monitoring report and correlate the total time, numbers of visit and page hits of the students. High total time does not guarantee the student is an active SPIN user. Nevertheless the study also found that there is a cheater in this system.
CONSTRUCTING PLACE AND SPACE IN THE DESIGN OF LEARNING ENVIRONMENTS FOR PBL IN MALAYSIAN UNIVERSITIES

ASEAN Journal of Teaching & Learning in Higher Education , 2009,
Abstract: Malaysia’s provisional entry into the Washington Accord has resulted in an overhaul of engineering education in this country. Gone are the days of traditional teaching in engineering. A myriadof changes have been introduced including changes in attitudes, orientation, curriculum, and delivery, to name a few. One important aspect that architects and planners have neglected is inthe area of educational infrastructure, namely the place and space of the learning environment. The advent of new teaching methods has brought with it different infrastructural needs. Problembasedlearning (PBL) is achieving great currency in engineering education these days. However, the present-day teaching-learning environment is seen as defective: it does not provide optimum learning in the PBL context. This paper attempts to reconsider the relationship of physical settings to the student learning experience. This paper will also look at the problems of place and space in the engineering education in Universiti Kebangsaan Malaysia, with a comparison made with the integrated architectural program, and provide examples of the environmental design that would be conducive to PBL

Abstract: The aim of this study is to identify and highlights the importance parts of a conservation programs, particularly for timber building. Masjid Lama Mulong is one of a remaining cultural heritage experiencing conservation works as to restore the uniqueness of the building and its history that once existed. Made from cengal, one of the famous local hardwoods, however, it is not spared to the threat of decay and deterioration from its agent. In conservation, one of the important stages is to inspect and investigate defects, as to assure the implementations of appropriate improvements are made accordance with the conditions and the state of deteriorations. In this part, some of the important features of the investigators should take into account before any investigation is made. From the overall investigation, defects are mostly caused by mechanical and biological category. Decay due to termite attacks and soft rot are among the highest rank which is mostly found contributed for the seriousness deterioration due to the presence of dampness.

Ribarstvo : Croatian Journal of Fisheries , 2011,
Abstract: Reduction and possible elimination of fish meal and fish oil from the nutrition of aqua cultural fish species is one of the priorities in nowadays research. Due to the growing needs for fish for human consumption and the cost of fishmeal respectively, the global trend of excessive fishing has up to now become a serious problem. Also, as global fish farming continues to increase, the need for good and cost-effective protein sources is increasingly important. Fish meal is still an essential ingredient in diets for carnivorous fish and fish meal availability in sufficient quantities for the future farming is questioned. Replacement of fishmeal in fish feed will lead to the commercialization of the alternatives, marine fish resources will be less exploited by the manufacturers and seafood farmers worldwide. The paper provides a review of scientific research on alternative dietary components used as a substitute in fish meal for various fish species and other aquaculture organisms.

Journal of the Geographical Institute Jovan Cvijic, SASA , 2012, DOI: 10.2298/ijgi1202049z
Abstract: The transition to a market economy in Serbia still hasn’t created a good enough environment for enterpreneurship to flourish. Enterpreneurship is more commonly manifested as a result of the push effect- the need for work and survival, and it’s success is the result of the pull effect- recognizing business possibilities and market chances. The economic crisis has further increased unwanted demographic movements, especially inside migration of younger and more educated population from rural areas to bigger cities. The only way to battle the high unemployment rate of women and the young in Serbia is to create more attractive conditions for the development of enterpreneurship. That can be acomplished by bettering the macroeconomic ambience of business as well as by funding the need for start-up capital. The first priority is to create the conditions necessary for safe and long term business development. [Projekat Ministarstva nauke Republike Srbije, br. 47007/III]

Abstract: The proposed influence of cosmic rays on cloud formation is tested for the effect of sudden intensity changes of CR (Forbush decreases) on cloudiness. An attempt is made to widen the investigated period covered by satellite observation of cloudiness. As an indicator of cloud cover, the diurnal temperature range (DTR - a quantity anticorrelated with cloudiness) is used. The superposed epoch analysis on a set of isolated Forbush decreases is conducted and the results for a region of Europe are presented. The effect of Forbush decrease on DTR is statistically significant only if the analysis is restricted to high amplitude FDs (above the threshold value of 7% with the respect to undisturbed CR intensity). The magnitude of the effect on DTR is estimated to be (0.38 ± 0.06) °C.

Abstract: The background spectrum of a germanium detector, shielded from the radiations arriving from the lower and open for the radiations arriving from the upper hemisphere is studied, both in a ground level and in an underground laboratory. It is established that the continuous portion of this background spectrum is mostly due to the radiations that arrive from the upper hemisphere of the continuous spectrum similar to the instrumental one. The intensity of this radiation of an average energy of about 120 keV is estimated to about 8000 photons/m2s 2\pi srad in a ground level laboratory, and to about 5000 photons/m2s 2\pi srad at the depth of 25 m.w.e. Rough estimates of the dose that it contributes to the skin are about 1.5 nSv/h and 1 nSv/h respectively. Simulations by GEANT4 and CORSIKA demonstrate that this radiation is both of cosmic and terrestrial origin, mixed in proportion that still has to be determined.
