A case of company manufacturing industrial valves is studied. To survive the fierce competition in the low-volume, high-complexity production environment, the company needs accurate information on the cost of its products. Current cost accounting system which allocates production costs based on the weights of intermediates and final products cannot provide accurate cost information that managers really need. Data on the company's cost structure and production processes were reviewed and managers were interviewed before problems with the current costing system were identified. Activity-based costing (ABC) system as well as an improved traditional costing system is considered to replace the current system. A prototype of ABC system is developed to better represent the relationships among the cost drivers, activities, and products.

Objectives Since the health insurance coverage for traditional Korean medicine is very low, some physicians and researcher have suggested that government's institutional support is needed for korean medicine field. Therefore We examine the use of traditional medicine and western medicine in Taiwan, which operates a similar health insurance system to Korea. Methods We selected several studies from Pubmed and NHIRD, that could be used to numerically evaluate the use of traditional medicine. We reviewed the current status of medical use in Taiwan and compare it with that of Korea. Results Through a total of 87 studies, We found that 26.59%~31% of Taiwanese use Traditional medical institutions more than once a year, and the use of traditional medicine has been increasing since 2000. In adults than children, in women than men, the use rate of traditional medicine was high. Especially, herbal medicine was the most common intervention, accounting for 70% of traditional medical care. Conclusions The core of low insurance coverage for traditional Korean medicine is in lack of coverage for herbal medicine. Taiwan's case shows that the unmet demand for traditional Korean medicine of the Korean population can exist widely.

Determining the number of operators who set up the machines in a human-machine system is crucial for maximizing the benefits of automated production machines. A man-machine chart is an effective tool for identifying bottlenecks, improving process efficiency, and determining the optimal number of machines per operator. However, traditional man-machine charts are lacking in accounting for idle times, such as interruptions caused by other material handling equipment. We present an adjusted man-machine chart that determines the number of machines per operator, incorporating idleness as a penalty term. The adjusted man-machine chart efficiently deploys and schedules operators for the hole machining process to enhance productivity, where operators have various idle times, such as break times and waiting times by forklifts or trailers. Further, we conduct a simulation validation of traditional and proposed charts under various operational environments of operators' fixed and flexible break times. The simulation results indicate that the adjusted man-machine chart is better suited for real-world work environments and significantly improves productivity.

This paper explains the concept of Economic Value Added (EVA) that is gaining popularity in India. We also examine whether EVA is a superior performance measure, both for corporate disclosure and for internal governance. Of late, companies in India have started focusing on shareholders wealth creation by adopting value-based models for measuring shareholder value that helps to align managerial decision-making with the firm preferences. In recent years, the EVA framework is gradually replacing the 'traditional' measures of financial performance on account of its robustness and its immunity from 'creative' accounting. Even though some leading Indian companies have already joined the band wagon of their American counterparts in adapting the EVA-based corporate performance systems, many other are hesitating as there is no strong evidence that the EVA system works in India. Till now, EVA disclosures are "not mandatory for the Indian companies." Also, we examine the value-creation strategies of selected Indian companies by analyzing whether EVA better represents the market-value of these companies in comparison to conventional performance measures. The study indicates that "there is no strong evidence to support Stern Stewart's claim that EVA is superior to the traditional performance measures in its association with MVA." As part of this study, we have also extensively surveyed the EVA disclosures in the Annual Reports made by the same sample group of 500 corporations from India.

Loyalty is a bonus point that a customer earns in reward of purchasing goods of a shop or a manufacturer. The management of loyalty such as issuing, accounting, reimbursing is carried out by the loyalty system. Traditional loyalty systems were proprietary. As a result, the systems are not interoperable with each other. However, our loyalty system allows a group of merchants join together and use the same IC card to operate their own loyalty programs. Data and counters can be shared or totally isolated, using secret codes and keys. The loyalty pool system communicates with the loyalty service providers over the Internet and performs the management of loyalty in fully automated manner. This paper describes the functional architecture and internal behavior of the loyalty pool system along with the communication protocols.

Most of the previous approaches to English agreement phenomena have relied upon only one component of the grammar (e.g., either syntax, or semantics, or pragmatics). This paper argues that interrelationships among different grammatical components play crucial roles in such phenomenon too (cf. Kathol 1999 and Hudson 1999). The paper proposes that, contrary to traditional wisdom, English determiner-noun agreement is morpho-syntactic whereas subject-verb and pronoun-antecedent agreement are reflections of index agreement (cf. Pollard and Sag 1994). The present hybrid analysis of English agreement shows the importance of the interaction of different components of the grammar in accounting for English agreement phenomena. In particular, once we allow morphology to tightly interact with the system of syntax, semantics, or even pragmatics, we could provide a solution to some puzzling English agreement phenomena. This allows a more principled theory of English agreement.

This paper introduces a novel approach to time-series estimation for energy load forecasting within Virtual Power Plant (VPP) systems, leveraging advanced artificial intelligence (AI) algorithms, namely Long Short-Term Memory (LSTM) and Seasonal Autoregressive Integrated Moving Average (SARIMA). Virtual power plants, which integrate diverse microgrids managed by Energy Management Systems (EMS), require precise forecasting techniques to balance energy supply and demand efficiently. The paper introduces a hybrid-method forecasting model combining a parametric-based statistical technique and an AI algorithm. The LSTM algorithm is particularly employed to discern pattern correlations over fixed intervals, crucial for predicting accurate future energy loads. SARIMA is applied to generate time-series forecasts, accounting for non-stationary and seasonal variations. The forecasting model incorporates a broad spectrum of distributed energy resources, including renewable energy sources and conventional power plants. Data spanning a decade, sourced from the Korea Power Exchange (KPX) Electrical Power Statistical Information System (EPSIS), were utilized to validate the model. The proposed hybrid LSTM-SARIMA model with parameter sets (1, 1, 1, 12) and (2, 1, 1, 12) demonstrated a high fidelity to the actual observed data. Thus, it is concluded that the optimized system notably surpasses traditional forecasting methods, indicating that this model offers a viable solution for EMS to enhance short-term load forecasting.

The study empirically examines the effects of loan portfolio diversification on bank risk and return in the nascent banking market of Vietnam. Loan portfolio diversification is captured through the Hirschman-Herfindahl index and the Shannon Entropy with sectoral exposures. We access each bank's financial reports to collect the required data, especially the breakdown of sectoral loan portfolios, thus constituting a unique dataset. To compute bank return, we use the traditional accounting indicators, including return-on-assets, return-on-equity, and net-interest margin. For bank risk, we utilize the loan-loss provisions and non-performing loans relative to gross customer loans. Using a sample of 30 commercial banks over the period from 2008 to 2019 and the system generalized method of moments estimator for the dynamic panel, we indicate the downsides of portfolio diversification. Concretely, we observe that all diversification measures exhibit significantly negative signs in all regressions across different bank return proxies. At the same time, the estimates display the significant and positive impact of diversification on the non-performing loan ratio. Hence, sectoral loan portfolio diversification significantly hampers bank performance in both aspects of lower return and higher credit risk. The results are robust across a rich set of bank performance and portfolio diversification measures.

The study aims to measures the service quality of Islamic banking in Malaysia from non-Malaysian customers' perspective based on the six different dimensions of the SERVQUAL model, namely, Shariah, assurance, reliability, tangibles, empathy and responsiveness. This study surveyed 100 non-Malaysian respondents from 25 different countries who have first-hand experience with Islamic banking services in Malaysia. The collected data were analysed by using the SPSS v23 for reliability analysis and descriptive statistics. The results indicates that customers' impressions of Islamic banks' service quality in Malaysia did not meet their standards. The independent variables, namely, compliance, assurance, reliability and empathy have positively affected customer satisfaction, while two dimensions, namely, tangibility and responsiveness does not significantly influence non-Malaysian customer satisfaction in the Islamic banking system in Malaysia. The findings of the study suggested that the Islamic banks should develop and obey the customer perception's policy by following customers' expectations and the results are also expected to include recommendations for improving the level of satisfaction of the Islamic banking system's foreign clients in Malaysia. Since this study was limited to Islamic banks in Malaysia, the findings may not be applicable to other traditional banks.

Traditional Industries were planning the major role for Taiwan's economy. However, we need to face the competition from developing countries. Moving manufacturing department to other low salary countries, such as China, can only temporarily release some limited pressure. The final and complete solutions are to equip on R&D, refine techniques, improve management capabilities, upgrade business, and reform physique. Currently there are some ERP systems on the market; however, they are designed for common purpose and difficult to introduce into industry. The expensive price is another factor to make them be popular. In this research we will Object Oriented, Visual Modeling, ER Model and Windows Environment to develop an Integrated Management System for Sports Requisites Industries (IMSSRI). We will integrate all information from all departments such as development, business, material administration, manufacture, shipping, and financial. When development people construct the all modules, components, cutting molds, materials and accessories, IMSSRI will calculate all needed materials and cost for each product. This cost will be used for quotation to report to our customers. When customers confirm the order, system will transfer all necessary materials into Material Administration System. IMSSRI can generate manufacturing forms and material raw lists for manufacture department. All related information such as stocking, returning goods, material requesting, and material returning can be integrated so we can control all details of the whole enterprise. Through the help of this system, we hope we can save man-power, reduce human mistakes, raise management capabilities for tradition manufacturing industries and create another possibility of eternal operating for Taiwan's Industries.
