Nepal is bestowed with abundant water. With more than 1500 mm average annual rainfall in the country, a vast quantity of underutilized groundwater in the Terai belt, and the water stored in snowcaps in the Himalayas, aquifers in the mountains and glacial lakes, Nepal is potentially in an advantageous position in terms of per capita availability. However, low emphasis in management aspect of water and high emphasis in infrastructural developments related to water resources management has resulted in conversion of water in Nepal from a resource to a burden. The global climate change, reduction in number of rainy days, increase in intensity of rainfall during wet monsoon season, encroachment of river banks for settlement, inadequate release of environmental flows from hydropower plants, and attempt to tame the mighty and high velocity rivers of Nepal have resulted in increasing number of water induced disasters (flood and landslide), rise in conflict between local residents and hydropower developers, higher number of devastating landslides, and in some extreme cases mass migration of residents resulting in climate refugees. There is a ray of hope; the awareness level of the people regarding sustainable use of water resources is increasing, the benefit sharing mechanism is gradually being implemented, the role of interdisciplinary and integrated water resources management is appreciated at a higher level and the level of preparedness against flood and landslides is at a higher degree compared to a couple of decades ago. With the use of renewable energy sources, the possibilities for sustainable and productive use of water are on the rise in Nepal.

The effect of pan frying method was evaluated for proximate composition of selected fish species Pampus argenteus, Lethrinus nebulosus and Acanthopagarus arabicus which were determined by standard procedures. Proximate compositions found in the frying fillets were different to the raw fish samples. The moisture content seems to decrease in all fried samples. The reason of moisture loss at the time of frying produced is excessive protein amount in fried fish as compare to raw fish. Protein content seemed to increase in Pampus argentus > Lethrinus nebulosus and >Acanthopagrus arabicus in their particular fried form. The outcomes shown that protein content was in the ranges of 14.83-25.07 g/100g in fried samples, while the fat content was between 3.76-9.77 g/100 g. The energy content was the highest in the fried fish Lethrinus nebulosus (236 kcal/100 g), Pampus argentus (161 kcal/100 g) and Acanthopagrus arabicus (135 kcal/100 g). The information achieved in this study would be very important to fish consumers, processors and nutritionists to academically increase their awareness regarding the nutrients contents in selected fish species.

The use of caffeine as a psychoactive stimulant in tea has been observed to have serious negative effects in humans' systems such as respiratory, nervous, cardiovascular, renal and skeletal systems. This study was carried out to assess the levels of caffeine in 10 different tea brands available in local market in Dutse, Jigawa State, Nigeria. Quantitative analysis of caffeine was performed by a simple and fast UV-Vis spectrophotometric methods using different solvents for extraction. The caffeine content in all the tea samples analyzed in this study were below the maximum allowable limits set by the USFDA. Tea have been associated with adverse health effects and the claims made by manufacturers about the benefits of tea do not highlight risks associated with excessive consumption of a combination of the ingredients contained in tea. Long term effects of tea consumption of children and young people have not been adequately studied. Therefore, it is recommended that further research be carried out on the adverse effects of energy drinks on children. Research is also needed to be done on the effects of the combination of ingredients on health and excessive consumption of those ingredients to children and adolescents. People need to be educated and given proper awareness on the health risks associated with caffeine containing beverages.

Purpose-Meat plays an important role in the Chinese daily diet, however, due to the spread of COVID-19, food supply and safety have become a major concern. The safety and health features of chilled fresh meat have attracted the attention of consumers. To study consumers' purchasing behavior and willingness to pay for chilled meat under the influence of the epidemic. Research methodology- The data were obtained by questionnaire survey, major issues include consumers' meat consumption habits in the wake of the COVID-19 and their awareness of meat product quality labels. In addition, the gender, age, family income, and other basic personal information of the interviewees were also counted. Based on the binary Logit regression method, we study consumers' purchasing behavior and willingness to pay for chilled meat under different demographic characteristics. Results-The results showed that brand and quality certification are important factors influencing purchases. In addition, the presence of children under the age of 12 in the household and the level of income and education also influence consumers' purchase intention of the chilled fresh meat. However, mart promotions and city ratings can significantly lower consumers' propensity to buy the chilled fresh meat. Apart from this, such factors as gender, age, and living conditions have no significant influence on consumers' purchase of chilled fresh meat.

최근 한정된 에너지를 기반으로 동작하는 센서 네트워크 환경에서 에너지를 효율적으로 사용하기 위한 많은 연구가 이루어지고 있다. 대표적인 연구로써 이벤트 발생 여부에 따른 노드의 가변 센싱 및 전송 기법의 경우, 특정 노드에서 네트워크 혼잡을 야기하여 전송 패킷의 손실 및 전송 모듈의 과다 사용으로 인한 네트워크의 수명이 감소하게 된다. 이를 해결하기 위해, 유전자 알고리즘을 기반으로 네트워크 패킷을 주변 노드로 분산시키는 TARP 가 제안되었다. 하지만 TARP 의 경우, 유전자 알고리즘의 핵심 단계인 적합도 평가에서 사용되는 적합도 함수에 인접 노드의 평균 데이터 전송량 및 데이터 분산만을 고려하여 트래픽을 분산하기 때문에, 전체 네트워크 수명에 대한 추가적인 고려가 필요하다. 이를 해결하기 위해 본 논문에서는 유전자 알고리즘 기반의 에너지 인식 트래픽 분산 기법을 제안한다. 제안하는 기법은 적합도 평가에서 잔여 에너지량 및 단일 노드의 데이터 전송량을 추가적으로 고려함으로써, 보다 효율적인 트래픽 분산을 수행하여 네트워크 수명을 증가시킨다. 제안하는 기법의 우수성을 보이기 위해 시뮬레이션을 통해 기존의 트래픽 분산 기법(TARP)과 제안하는 기법과의 성능을 비교하였다. 그 결과 기존 기법에 비해 평균 27% 이상의 네트워크 수명의 향상을 보였다.

Heterogeneous computing is a technology that utilizes different types of processors to perform parallel processing. It maximizes task processing and energy efficiency by leveraging various computing resources such as CPUs, GPUs, and FPGAs. On the other hand, edge computing has developed with IoT and 5G technologies. It is a distributed computing that utilizes computing resources close to clients, thereby offloading the central server. It has evolved to intelligent edge computing combined with artificial intelligence. Intelligent edge computing enables total data processing, such as context awareness, prediction, control, and simple processing for the data collected on the edge. If heterogeneous computing can be successfully applied in the edge, it is expected to maximize job processing efficiency while minimizing dependence on the central server. In this paper, experiments were conducted to verify the feasibility of various parallel programming models on high-end and low-end edge devices by using benchmark applications. We analyzed the performance of five parallel programming models on the Raspberry Pi 4 and Jetson Orin Nano as low-end and high-end devices, respectively. In the experiment, OpenACC showed the best performance on the low-end edge device and OpenSYCL on the high-end device due to the stability and optimization of system libraries.

This study aims at giving the framework to estimate the environmental load at planning and schematic phase. With increasing awareness of environmental issues, the effort to reduce the environmental impacts caused by human activity has been increasingly enlarged. So far most of researches estimating CO₂ emissions have analyzed energy consumption based on BOQ (Bills of Quantity) acquired after detailed design. There is also lack of reliability in the estimated environmental impact using the basic unit of a facility at the planning stage, because it uses a limited specific section of historical data. Thus, this study is targeted at developing framework to assess reliable environmental loads based on information available at project early phases by making case-bases from historical design information on PSC Beam Bridge. Historical database is built on the basis of the LCA (Life Cycle Assessment) and in order to set input information for estimating model, the literature about information in an early project phase are reviewed. Using the information available in the planning and schematic design stage, the Framework is presented to estimate the environmental load in an early stage in the project. Developing an environmental load estimation model in accordance with the Framework presented in this study, it is expected that the environmental load in the initial project phase can be estimated more quickly and accurately.
