Weaning pigs often face post-weaning challenges such as diarrhea, low feed intake, and body weight (BW) loss which affects the health and economic value of weaning pigs. Interestingly, the use of yeast cultures (YCs) as feed supplements for pigs has increased markedly in recent years. This study evaluated the effects of yeast cultures (Saccharomyces cerevisiae) on the growth performance, fecal score, and nutrient digestibility of weaning pigs. A total of 50 crossed healthy weaning pigs [(Yorkshire ${\times}$ Landrace) ${\times}$ Duroc] with an average BW of $7.46{\pm}1.60kg$ (28 day of age) were used in a 6-week experiment. The experiment was divided into 3 phases (Phase 1, 1 - 2 weeks; Phase 2, 2 - 4 weeks; Phase 3, 4 - 6 weeks). Dietary treatments were as follows: 1) CON: basal diet and 2) CON + 0.50% YC. During phase 1, the average daily gain (ADG) and average daily feed intake (ADFI) were significantly increased (p < 0.05) in the weaning pigs fed YC supplementation diets compared with the weaning pigs fed the CON diet. During phase 3 as well as overall, the gain/feed ratio (G/F) was significantly increased (p < 0.05) in the YC supplementation group compared with the pigs fed the CON diet. In conclusion, the supplementation of YCs in the diet positively affected the growth performance of weaning pigs during the first two weeks after weaning.

Information and communication technologies (ICTs) have always mattered in agriculture too. In day-to-day practices of agriculture and allied sectors, the farmers often share their information. Changing weather patterns, soil conditions, pests and diseases always throw challenges to small and marginal farmers. So, the farmer needs up-dated information to cope with and even benefit from these changes. In the developing countries like India, where agriculture still plays a crucial role (over 58% of the rural households depend on agriculture as their livelihood) and the rising population from 1027 million to 1419 million during 2001-16 (a total rise of 38 percent or 1.3 percent per year) pose a lot of pressure on land and other resources to meet the food security needs on one hand and to meet the challenges of globalization on the other. Understanding and addressing these challenges are very crucial, in which ICT can play a major role. With the booming mobile, wireless, and Internet industries, ICT has found a foothold even in poor marginal and smallholder farms and in their activities. The survey conducted among the 120 farmers in Srikakulam district in India revealed that, ICT has revolutionized the agriculture in the modern days. Production and marketing information is accessed by 91% of the sample farmers through mobile in 2015, where it was only 5% in 2005. The extent of use of mobile phones by the farmers varied with the decision to be taken by them like Harvesting, packing, and storing (94%), Selling Decision (91%), Seed purchase (89%), Application of fertilizers and pesticides (88%) and Land preparation and planting (84%), other package of practices (77%). The farmers further opined that, 'Voice' was the dominating source of communication (96%) compared to Short Message Service (SMS) (only 27%) and Internet access (10%), as majority are illiterate. The use of camera (71%), Bluetooth (33%), Radio (61%) TV (41%) are the other means of sharing the information. In this context of importance of ICTs in Indian agriculture, greater attention justifies about the applications of ICT's to alleviate poverty and promote economic growth of the farming population.

Objectives: This study aimed to investigate the nutritional status and dietary behavior of adolescents from North Korean refugee (NKR) families residing in South Korea (SK), who are known to be at a higher risk of malnutrition due to their lower socioeconomic status and facing other psychological challenges. Methods: A total of 178 adolescents (91 males and 87 females) from NKR families were included in the analysis, and their demographic details such as age, birthplace, parental nationality, and duration of their settlement in SK were collected through questionnaires. Anthropometric measurements were also taken to determine their growth and nutritional status according to the 2017 Korean National Growth Charts for children and adolescents. The study used the Nutrition Quotient for Korean Adolescents (NQ-A) questionnaire to assess the dietary behavior of the participants. Results: Approximately 11.8% and 10.1% of participants were identified with malnutrition and obesity, respectively. The total mean score for the NQ-A was 50.1. The mean scores for the individual factors of balance, diversity, moderation, environment, and practice were 49.2, 44.7, 43.8, 51.2, and 61.5, respectively. Approximately 47.2% of participants had a low NQ-A grade. However, there was no significant difference in the NQ-A scores according to their nutritional status or duration of time in SK. Conclusions: Adolescents from NKR families exhibited both malnutrition and obesity. However, their dietary behavior, as assessed using the NQ-A, did not vary with their nutritional status. The unique challenges and related dietary behavior of North Korean adolescent refugees should be taken into consideration, when developing targeted strategies for nutritional education and health management programs.

The fusion of learning, information, and technology presents dynamic challenges for all librarians, educators and students in 21st century libraries and schools. At the heart of this fusion is the growth of a pervasive, integrated information environment characterized by vast quantities of digital content, open choice, collaborative and participatory digital spaces, and the transition of the web environments from consumption of information to creation of information. This environment heralds important opportunities for librarians and teachers to rethink, re-imagine and recreate a dynamic approaches to information literacy instruction. Drawing on an extensive body of research undertaken through the Center for International Scholarship in School Libraries (CISSL), and published research on both information literacy and constructivist learning, this paper provides a critical examination of the current status of information literacy: its multiple conceptualizations, competing models, viewpoints, and its operationalizations in educational and library environments. The paper will challenge information literacy practices which center on simplistic, reductionist approaches to information literacy development, and the separation of information process and knowledge content. In particular it will address apparent contradictions in espoused conceptions of information literacy which revolve around "knowledge": knowledge construction, critical thinking, problem solving and the development of knowledgeable people; and information literacy practices which revolve around "information": a predominant focus on skills of access and evaluation of resources and with less attention given to engaging with found information to develop deep knowledge and understanding. The paper will present a series of challenges for moving forward with information literacy agendas in libraries and schools.

The entrepreneurial journey is not short of challenges, and about 90% + tech start-ups experience failure (Startup Genome, 2019). The magnitude of the challenges varies across the tech start-up lifecycle stages, namely emergence, stability, and growth. This opens the research question, do the profiles of a start-up and its co-founder impact start-up success or failure across its lifecycle stages? This study aims to understand and identify the profiles of tech start-ups and their co-founders. We gathered primary data from 151 start-ups (Status: 101 failed and 50 successful ones), and they are across different lifecycle stages and represent six major start-up hubs in India. The chi-square test on status and start-up's lifecycle stage indicates a noticeable correlation, and they are not independent. The Kruskal Wallis test was used to distinguish statistically significant profile attributes. The parameters distinguishing success and failure are identified, and the need to deliver customer experience is emphasized by the start-up profile attributes: Product/service, high-tech nature of a start-up, investor fund availed, co-founder experience, and employee count. The importance of entrepreneurial experience is ascertained with entrepreneur profile attributes: Entrepreneurial expertise, the number of prior and current start-ups, their willingness to start again in the event of failure, and age of co-founder, which is a proxy to learning and experience. This study has implications for entrepreneurs, investors, and policymakers.

Multimedia computing has attracted considerable attention with the rapid growth in the development and application of multimedia technology. Current studies have attempted to support the increasing resource consumption and computational overhead caused by multimedia computing. In this paper, we propose $MediaCloud$, a new multimedia computing paradigm that integrates the concept of cloud computing in handling multimedia applications and services effectively and efficiently. $MediaCloud$ faces the following key challenges: heterogeneity, scalability, and multimedia Quality of Service (QoS) provisioning. To address the challenges above, first, a layered architecture of $MediaCloud$, which can provide scalable multimedia services, is presented. Then, $MediaCloud$ technologies by which users can access multimedia services from different terminals anytime and anywhere with QoS provisioning are introduced. Finally, $MediaCloud$ implementation and applications are presented, and media retrieval and delivery are adopted as case studies to demonstrate the feasibility of the proposed $MediaCloud$ design.
