The Novel Coronavirus has been affecting several regions across the globe. It is noticeable that several countries address the problem better than other nations due to social and economic factors. With this, the present study distinguished and analyzed the state of two countries, the Philippines and South Korea, in the current pandemic, in relation to their socio-economic factors. The data was obtained from online platforms and trackers, and these were statistically analyzed using joint probability distribution, one sample t-test, confidence intervals, and normal distribution. Upon performing the calculations, the study found out that South Korea has a better situation in the pandemic compared to the Philippines, since the said country had implemented commendable measures.

The purpose of this study is to evaluate the effect of quality management practices on customers, employees and service quality in the financial service industry. The sample of 30 customers and 30 employees were selected based on stratified and snowball sampling procedures respectively. This research used a mixed approach to collect data. The study was conducted by engaging with customers (business owners, students and the working class) in the form of interviews and questionnaires, and by using secondary data. The main quality principles was mainly based on employee satisfaction, customer focus and continual improvement to establish how customers choose the bank they bank depending on their different classes. The results reveal that employee satisfaction had a direct relationship with the level of quality the organization produced. In addition, business owners and the working class were more likely to consider the service quality of the organization before they decide to bank with them. This research shows the significance of the implementing quality practices in the financial service industry in order to gain or retain customers.

Although firms devote much attention to outbound open innovation for economic or strategic benefits, how outbound open innovation is conducted effectively is still under-studied in the literature. Our paper introduces innovation intermediaries as an antecedent, and based on capability-based framework for open innovation and institutional theory constructs a moderated mediation mechanism through which innovation intermediaries influence outbound open innovation in China. The results of empirical test show that innovation intermediaries influence outbound open innovation via desorptive capacity, particularly in the form of two parallel routes, namely via identification capacity and transfer capacity. The relationship between innovation intermediaries, desorptive capacity and outbound open innovation is stronger in underdeveloped regions than in developed regions.

There has been a growing interest in collecting recyclable waste to reduce total carbon emissions, generate economic growth, and promote total lifecycle sustainability. This paper studies capacitated vehicle routing problem (CVRP) related to recyclable solid waste collection. The problem differs from the classical CVRP in terms of considering a separate recycling station in addition to the main depot. Genetic Algorithm (GA) and Seed Genetic Algorithm (SGA) hybridized with Greedy Algorithm are proposed. The objective of this study is to determine the optimal routes for the collection and delivery of recyclable solid waste. Hybrid GA and hybrid SGA are used to find the optimal solution while minimizing the total traveling distance. In addition, a web-crawling bot is developed to generate the matrix of real distances rather than considering the Euclidean distances. A real case of collecting recyclable waste in Yerevan, Armenia by an NGO has been studied to evaluate the effectiveness of the proposed approach. The results show that SGA provides better solutions than GA, and that these algorithms are better than the solution adopted by the NGO.

This article presents a decision-making model in food recall. Four options can be selected for treating recalled products: disposed, redirected for other use, downgraded, and reprocessed. The model will help stakeholders to decide how the recalled products should be allocated for each follow-up action to minimize the recall cost. The model has been tested on a real recall case in the edible oil industry. The model is proven to be able to find the optimal allocation for recalled products to produce a minimum recall cost. The sensitivity analysis shows that the recall cost can also be reduced by a product pricing strategy. Downgrading is the most favorable decision in the real case example.

Industrial robots have served industry for decades, especially the automotive industry. The traditional industrial robotics have shown their limits in task management due to the rigid and time-consuming programming and task planning. In recent years, to achieve the Industry 4 transformation, a broad range of collaborative robots (cobots) have been employed for autonomously executing tasks in different domains. Cobots, mainly used in manufacturing, were extensively developed, and integrated into real production contexts to optimise processes and improve productivity. However, motion control and programming for cobots remain an obstacle to achieve their potential as the procedure still takes time and disrupts processes. This paper critically reviews current mainstream control methods for industrial robotics to execute tasks and proposes an approach for rapid task re-planning for cobots in a flexible assembly workcell. The proposed method allows cobots to execute flexible assembly tasks for small batch production/assembly, or even single products and to re-plan the new task without interruption. Its advantages and limitations are also discussed.

The objectives of this study are to explore the core competency content of EECS (electrical engineering & computer science) students, as well as the current situation of training. In addition, first-year students from the college of electrical engineering & computer science of a university of technology underwent questionnaire surveys before and after the semester. There were 271 effective questionnaire copies, accounting for the effective recovery rate of 84.7%. Targeting the survey results, paired sample t-test analysis was carried out. Research findings show that the college of electrical engineering & computer science students showed remarkable improvement after the semester in terms of their competency in experiment design, execution competency, data analysis, and explanation. The results showed a considerable a little decrease but without significant difference in competencies such as professional ethics and social responsibility comprehension, work ethics and attitude cultivation, and mathematics, science, and engineering knowledge applications. We should assist students to strengthen these abilities.

In this paper, the use of the Data envelopment analysis(DEA) as a quick-and-easy approach for bankruptcy-based performance assessment is presented. The attractive advantage of DEA is that it can provide an efficient target(improvement goal) for inefficient decision-making units(DMUs). The DMUs under evaluation are divided into two groups: efficient and inefficient, regarding cases of bankruptcy analysis, they are divided into non-default firms and default firms. Moreover, the least-distance(LD)DEA model has been actively researched and applied, because it can provide the closest efficient target that is achievable with the least effort. Thus, using the LD-DEA model for bankruptcy-based performance assessment can give an early warning of a firm’s financial performance and provide an improvement goal that can be easily achieved for default firms. As a case study, we demonstrate this approach using financial data of 61 Japanese banks. From the results, we find that our approach provides an improvement goal that can be achieved with fewer total modifications of inputs and outputs compared with that provided by slacks-based measure(SBM) model.
在本文中，使用数据包络分析(DEA)作为破产为基础的绩效评估的快速和简单的方法提出。DEA的诱人之处在于它可以为低效决策单元(dmu)提供一个高效的目标(改进目标)。被评估的dmu被分为两组:高效和低效，对于破产分析的案例，它们被分为非违约企业和违约企业。此外，最小距离DEA模型(least-distance DEA model, LD)由于能够以最少的努力提供最接近的有效目标而得到了积极的研究和应用。因此，使用LD-DEA模型进行破产绩效评估可以对企业的财务绩效进行早期预警，并为违约企业提供易于实现的改进目标。作为案例研究，我们使用61家日本银行的财务数据来证明这种方法。从结果中，我们发现，与基于松弛的度量(SBM)模型相比，我们的方法提供了一个改进目标，可以通过更少的输入和输出修改来实现。

Process Capability Index (PCI) is often applied to measure the process’s ability of performance within functional specifications under controlled conditions. Thus, PCI can be used to evaluate the manufacturability of the product with given processes; namely, given its process setting and natural variation. However, initial process setting may become false setting and process variance may decrease because process deterioration and learning process respectively. These two effects may occur simultaneously and could be dependent for some case. In these regards, this research presents PCI expression which considers process deterioration and learning effect concurrently. The possible applications for presented PCI expression should not limit only for on-line process evaluation but also for off-line product and process design.
