Infrastructure is one of the most critical factors for economic development in the post-COVID -19 because it will interact with the economy through the production processes and this will greatly impact the production and performance of SMEs in terms of output, income, and employment. This paper examines the effect of infrastructure deficit on the performance of small and medium-sized enterprises in Benue State. The study is aimed at identifying the state of infrastructure and the effect of infrastructure deficit on the performance of small and medium-sized enterprises in Nigeria. Three stages random sampling technique was employedtoselect750 SME’s in Nigeria. The study employed descriptive statistics and the Cobb-Douglas Production Function to analyze data. The descriptive statistics resultsshowthat88.9 percent of the SMEs emphasized that the state of infrastructure is poor in Nigeria while 79.1 percent of SMEs opined that poor state of infrastructure increased their cost of operation in the post-COVID -19.The Cobb-Douglas Production Function result showed that infrastructure deficit hurts the performance of small and medium-sized enterprises in Nigeria in the post-COVID -19.Thestudyconcludesthatinfrastructure has a multiplier effect on SMEs ’income. Deficiency infrastructure hampered the development of SME’s and this translates in to a fall in income, low revenue to the government as well as increase unemployment. The study recommended that governments should make policies that are infrastructure driven in other to encourage and allow entrepreneurs to gain more access to infrastructure to reduce cost and enhance SMEs' performance.

This study was aimed at improving  the speaking learning process to the students of grade VIII at SMPN 3 Cilacap through games in the academic year of 2013/2014. This classroom action research was carried out in two cycles. The cyclical design consisted of four main steps: (1) planning, (2) action, (3) observation, and (4) reflection. Various games with some supporting activities were implemented in this study. The data were gathered through observations, interview, rating, video/audio recording, and performance tests. The data were analyzed using the interactive qualitative data analysis and descriptive statistics.  The findings show that games which are set up properly involved preliminary activities, game play and closure, together with some supporting activities are able to improve the speaking learning process. The implementation of games is effective to lessen the interference of the native language, lessen the students’ domination in the class, encourage the students’ initiation to speak English, give the students plenty of opportunities to speak as often as possible and encourage the students to focus on fluency rather than accuracy, encourage the students’ confidence, and increase the students’ involvement in the learning process. These improvements lead to the improvements of the students’ speaking skills. The students’ average score in performance test before implementing the actions is 63,39 while after implementing the actions is 81,64. It shows that it increases about 28,77%. It can be inferred that the students’ speaking skills improved after the implementation of the games.

Abstract Breeding value of sport horses in Poland is estimated on the basis of, among others, results of the 100-day performance test of young stallions in the training centres. However recently, a drastic decrease has been reported in the number of stallions undergoing this way of assessment in Poland with an increase in foreign breeds in equestrian competitions. The objective of the study was to determine variability level of stallion traits evaluated in the training centres and to identify factors affecting stallion performance value assessment during the stationary performance test. The study included 503 stallions subjected to the 100-day training followed by the performance test in the years 2004-2013 at the training centres. There were computed statistical characteristics of 16 performance traits which were scored by the trainer of the training centre, judging commission and test riders. Influence of identified factors on each evaluation was established using the GLM procedure. The rank correlations served to estimate phenotypic interdependencies between the scores and performance value indices. It was stated that the studied group of stallions showed low variation within the body basic measurements and the conformation correctness evaluated on the 100-point scale was also found within an average value (78.86 pts), quite close to minimum value for young stallions in Poland (78 pts). The highest variation was observed for the scores given by the test riders and the main factor differentiating the performance value of horses was their origin-breed group. The horses of the German breeds (HANN, OLDBG, HOLST) earned the highest scores, while Wielkopolska horses got the lowest scores for performance test. Insufficient consistency between the individual evaluation made by the trainer of training centre and the judging commission may imply completely different period of assessment (trainer - 100 days, judging commission - 2 days) or unsatisfactory competencies of examiners.

В симментальской породе предусматривается разведение скота, сбалансировано сочетающего молочную и мясную продуктивность. Однако в практике совершенствования племенных стад в подборах быков доминируют улучшатели удоя, что во многом предопределяет результаты селекции и продуктивный тип животных. Объектом нашего исследования стало стадо чистопородного симментальского скота в условиях стойловой системы беспривязного и привязного содержания коров. Для изучения эффективности использования быков-производителей разного племенного достоинства сформировали 2 опытные группы: I состояла из бычков, полученных от отцов с племенной ценностью (ПЦ) по удою 100 кг и более, а во II с ПЦ от 0 до 100 кг молока. Симментальские бычки, отобранные для контрольного убоя, достигали весовых кондиций 500 кг и более в 17,5 мес при среднесуточном приросте 911 г. При использовании на маточном поголовье быков-производителей с улучшающим эффектом по удою 100 кг и более, их сыновья (I группа), на фоне более высоких суточных приростов (на 30 г) и раннем возрасте достижения живой массы 500 кг (на 18 дней) имели массу и выход туши на 21,4 кг и 2,7 ниже, чем у бычков II группы. При формировании молочно-мясного типа быки-производители с умеренной племенной ценностью по удою обеспечивали получение потомства, сочетающего молочную и мясную продуктивность в экономически значимых пропорциях.The Simmental breed provides for the breeding of cattle that combines milk and meat productivity in a balanced proportion. However, in the practice of improving breeding herds, the selection of bulls is dominated by milk yield improvers, which largely determines the results of selection and the productive type of animals. The object of our research was a breeding herd of purebred Simmental cattle in variety feeding and housing practices. To study the effectiveness of using bulls-producers of different breeding values, 2 experimental groups were formed: I consisted of bulls received from fathers with a breeding value (BV) of milk yield 100 kg or more, and II with a BV from 0 to 100 kg of milk. Simmental bulls selected for control slaughter reached weight standards of 500 kg or more in 17.5 months with an average daily increase of 911 g. When used on breeding of bulls with an improving effect on the yield of 100 kg or more, their sons (group I), against the background of higher daily gains (30 g) and an early age of reaching a live weight of 500 kg (18 days), had a mass and carcass yield of 21.4 kg and 2.7 lower than that of group II bulls. When forming a dairy-meat type, producing bulls with a moderate breeding value for milk yield provided for the production of offspring that combined dairy and meat productivity in economically significant proportions.

Rice being a staple food crop of Kashmir valley, the focus is on enhancement of yield in order to meet the needs of ever-growing population.Identification of new parental lines is crucial for developing ecology-specific hybrids with ideal agronomic performance. Exploitation of heterosis in the form of hybrid rice technology can be one of the approaches to increase productivity in this crop, especially exploiting diversity among japonica lines can serve as an excellent route.A number of CMS lines suitable formountainous areas of Kashmir have been developed, however, the availability of promising restorer lines remains to be the major limitation for utilization of these lines.Identification of potential restorers acts as the main limiting factor for hybrid development in the Kashmir valley. Marker based screening for Rf3 and Rf4 fertility restorer genes can be helpful in rapid selection of restorer lines while dealing with the large quantity of genetic materials. In the present study, 100 rice germplasm were screened with the help of SSR markers, RM3148 and RM6100linked to Rf3 and Rf4 genes on chromosome 1 and 10, respectively. In total, 19 lines revealed the presence of both Rf3 and Rf4 genes. These lines amplified fertility restorer specific alleles for both the genes and may serve as potential restorers for obtaining heterotic rice hybrids. Further the germplasm lines were also evaluated for yield and quality traits.The present results would help in selection of suitable restorers along with preferred grain shape/size.

Redundant Systems

Optimal exploration of engineering systems can be guided by the principle of Value of Information (VoI), which accounts for the topological important of components, their reliability and the management costs. For series systems, in most cases higher inspection priority should be given to unreliable components. For redundant systems such as parallel systems, analysis of one-shot decision problems shows that higher inspection priority should be given to more reliable components. This paper investigates the optimal exploration of redundant systems in long-term decision making with sequential inspection and repairing. When the expected, cumulated, discounted cost is considered, it may become more efficient to give higher inspection priority to less reliable components, in order to preserve system redundancy. To investigate this problem, we develop a Partially Observable Markov Decision Process (POMDP) framework for sequential inspection and maintenance of redundant systems, where the VoI analysis is embedded in the optimal selection of exploratory actions. We investigate the use of alternative approximate POMDP solvers for parallel and more general systems, compare their computation complexities and performance, and show how the inspection priorities depend on the economic discount factor, the degradation rate, the inspection precision, and the repair cost.
