Seaweed by-products have been dumped into the sea and induced marine pollution. However, they can be recycled as a valuable natural resources. Approximately 240,000 tons of sea mustard and kelp by-products were estimated to be producted during the last three years. The estimate corresponds 6.7% of the total production of marine aquaculture and 14.9% of the total production of seaweeds. When adding up the by-products from fish and mollusks, approximately 1,000,000 tons of fisheries by-products were thrown out into the sea every year. A three-step strategy is required for the industralization of fisheries by-products. The first step is the construction of the processing foundation of by-products, the second is its food industralization, and the third is its recycling as raw biomaterials. The stable supply of raw materials is the prerequisite for the industralization. Thus, it is necessary to construct the refuse logistics around chief production districts and to build the processing facility and frozen storage of by-products. Cooperation among private enterprises and government investment for research and development is required the second and third steps.

The world of smart agribusiness is still far from being fully and effectively applied by the Italian entrepreneurial fabric. In part, this is due to the fact that its potential and important connections with the technological world of reference are not fully known. The imperative is therefore: to learn how to manage all the processes that characterize the agricultural chain in a synergistic way, from production to the sale of the product to the final consumer. It is therefore essential to know every minimum aspect of the supply chain considering the current strengths on which to leverage but especially the weaknesses on which to intervene thanks to the use of technology available on the market. Today, the supply chain is still considered as a set of phases, one consecutive to the other, as if they were detached from each other. However, in order to operate efficiently, each step should be interconnected: from the farmer’s decision to produce an agricultural good to the choice of production factors, from the implementation of harvesting and post-harvest operations to processing, from the selection of goods suitable for sale to the logic of distribution on the target territory. This work investigates the potential strategy using digital technologies in order to make dynamic the agribusiness supply chain, especially because in Italy the agri-food is one of the most important economic sectors but it is far from the most innovative trends available on the market.

Background: Stroke patients have leg muscle weakness and impaired balance resulting in compensatory changes. To restore balance in these patients, functional training using postural strategy is needed. Objective: To examine the effects of ankle and hip strategy training on the center of pressure (COP) movement and limits of stability (LOS) in standing posture in stroke patients. Design: The study was an assessor-blinded and randomized-controlled clinical trial. Methods: Thirty patients were randomly assigned to an ankle strategy training group and a ankle/ hip strategy training group. Patients in the ankle strategy training group underwent ankle strategy exercise for 30 min, and those in the ankle/ hip strategy training group underwent 15 min of ankle strategy exercise and 15 min of hip strategy exercise. Both groups underwent training thrice a week for four weeks. Forward, backward, paretic side, and non-paretic side COP movements and LOS were measured using BioRescue. Results: After the intervention, except for the backward area in the ankle strategy training group, the COP movement area and the LOS were significantly improved in both the groups. In addition, these improvements were significantly higher in ankle/ hip strategy training group than that in the ankle strategy training group. Conclusions: Ankle strategy training in addition to hip strategy training improves COP movement (forward-backward, paretic side area, and nonparetic side area) and LOS in stroke patients.

본 연구는 시설토마토 재배지에서 push-pull 전략을 이용해 담배가루이와 천적곤충의 행동을 제어함으로써 담배가루이(Bemisia tabaci)를 친환경적으로 방제하기 위한 기술을 개발하고자 수행하였다. 담배가루이는 노란색에 유인율이 가장 높았으며, 520 nm의 광원에는 유인반응을 복합광원인 450 + 660 nm의 광원에는 회피반응을 보였다. 천적곤충인 담배장님노린재(Cyrtopeltis tenuis)와 미끌애꽃노린재(Orius laevigatus)는 모두 520 nm의 광원에 가장 높은 유인반응을 보였다. 휘발성 물질로는 ocimene과 carvacrol에 대해 기피반응을, methyl isonicotinate에는 유인반응을 보였다. 토마토 온실에 메밀을 투입하였을 경우 천적곤충인 담배장님노린재의 밀도는 무처리 대비 15일간 약 16배로 높게 유지되었다. Push-pull 세부전략들을 종합 처리한 결과, 처리 50일 경과 후 담배가루이의 트랩당 밀도는 무처리 대비 3배 이상 낮게 나타났으며, 이에 따른 시기 별 방제효과는 시간이 경과함에 따라 증가하는 경향을 보인 가운데 최고 68.7%였다.

While the reverberation mapping technique is the best available method for measuring black hole mass in active galactic nuclei (AGNs) beyond the local volume, this method has been mainly applied to relatively low-to-moderate luminosity AGNs at low redshift. We present the strategy of the Seoul National University AGN Monitoring Project, which aims at measuring the time delay of the Hβ line emission with respect to AGN continuum, using a sample of relatively high luminosity AGNs out to redshift z ∼ 0.5. We present simulated cross correlation results based on a number of mock light curves, in order to optimally determine monitoring duration and cadence. We describe our campaign strategy based on the simulation results and the availability of observing facilities. We present the sample selection, and the properties of the selected 100 AGNs, including the optical luminosity, expected time lag, black hole mass, and Eddington ratio.

한국과 중앙아시아 국가들 간의 외교 관계는 1992년에 성공적으로 수립되었는데, 이것은 이미 지금까지 27 년 동안 발전해 왔다. 계속되는 양국 관계의 심화와 함께 한국과 중앙아시아 국가들 간의 경제 및 무역 관계가 강화되었고, 양국간 교류 빈도도 현저히 증가했다. 아시아에서 네 번째로 큰 경제 대국인 한국은 중앙아시아에서의 경제 및 외교 전략에서 더 큰 잠재력을 보이고 있다. 특히 한국은 2013년 '유라시아 이니셔티브'와 2017년 '신북정책'을 제안해 중앙아시아 국가들이 중요한 파트너로 평가받았고, 보다 적극적인 경제협력 전략이 추진될 것으로 보인다. 따라서 향후 한국과 중앙아시아 국가 간 경제협력이 뚜렷하게 발전할 것으로 보는 것이 타당하다.

A typical Mathematics class is comprised of a heterogeneous group of students in terms of academic ability, learning styles, intelligence quotient, home background and the likes. The inability of the teachers to effectively manage these differences usually leads to poor academic achievement among the learners, especially the weak ones. This study therefore determined the effectiveness of Cooperative Learning Technique on low learning ability students in Mathematics. Quasi-experimental research design was adopted. The sample size purposively selected consisted of 137 students from four schools in Education District II and IV, Lagos State, Nigeria. Two hypotheses were raised and tested at 0.05 level of significance. The collected data were analyzed using t-test. The result of the analysis revealed that cooperative learning strategy enhanced the low ability students’ achievement in Mathematics. Also, cooperative learning strategy enhanced low learning abilities students in understanding mathematics irrespective of their gender. It is therefore, recommended that teachers should adopt the cooperative learning strategy to teach Mathematics. For teachers to be more conversant with the use of cooperative learning strategy, as well as other interactive methods of teaching mathematics, workshops and conferences should be organized for secondary schools on the use of different methods of teaching learners from different ability levels, especially cooperative learning strategy.
