Breakthrough of the Bottleneck in the Application of Management Accounting——Insights from Events Accounting

The purpose of management accounting information system is to serve for management. Since 1980＇s, innovations in management-have seen the application of several accounting techniques such as activity-based costing, balanced scorecard and target costing. However, subsequent surveys have shown that the application of these innovative management accounting techniques is not widespread. Indeed, the application of many techniques has been decidedly ephemeral. The authors suggest two important and interrelated reasons for the apparent failure to adopt such techniques. First, the absence of a conceptual framework needed to envision the collection and integration of multi-dimensional data needed in the modern organization. The second reason is the failure to exploit the data handling potentialities offered by modem computer systems. Reconstruction of contemporary management accounting system using insights from principles of events based accounting is offered as possible solution.

Application of quantitative imaging in oncologic management

Medical imaging, such as computed tomography （CT）, magnetic resonance imaging （MRI） and positron emissiontomography （PET）, plays a vital role for the decision-making in oncologic management. In clinical practice, imaging-derivedtumor metrics are routinely applied in oncologic management as an imaging biomarker. For example, the ResponseEvaluation Criteria in Solid Tumors （RECIST） are commonly used for tumor treatment response evaluation based on thedynamic changes in tumor size. However, the current cross-sectional images are interpreted qualitatively for lesioncharacterization, treatment response evaluation and prognostic prediction by highly trained radiologists, which hasincreasingly apparent limitations. Therefore, there is a demanding shift toward more quantitative imaging interpretation.

Effects of Nitrogen Application Rate and Ratio on Lodging Resistance of Super Rice with Different Genotypes

The objective of this study was to determine the morphology mechanism of nitrogen （N） fertilizer rates and ratio on lodging resistance through analying its effects among lodging index （LI）, lodging-related morphological traits and physical strength in basal intemodes by comparing japonica and indica super rice cultivars. Field experiments, with three nitrogen levels （0, 150 and 300 kg ha-L） and two ratios of basal to topdressing （8：2 and 5：5） with two super rice cultivars （Yliangyou 2 and Wuyunjing 23）, were conducted in the Baolin Farm, Danyang Country, Jiangsu Province, China, in 2011 and 2012. Effects of N fertilizer rates and ratios on morphology of whole plant, morphology traits in basal intemodes and culm＇s physical strength parameters were investigated at 20 d after full heading stage. LI of Yliangyou 2 was significant greater than that of Wuyunjing 23 due to larger bending moment by whole plant （WP） with higher plant height and gravity center height. With higher volume of N fertilizer, LI of two super rice cultivars was increased conspicuously. However, no significant effect was detected with increase of panicle fertilizer ratio. The size of breaking strength （M） in basal intemodes was the key factor determining LI among N fertilizer treatments. Correlation analysis revealed that M value was positively related bending stress （BS） of Wuyunjing 23 and section modulus （Z） of Yliangyou 2, respectively. The higher N fertilizer levels induced reduction ofBS of Wuyunjing 23 due to weak culm and leaf sheath plumpness status and reduced Z of Yliangyou 2 owning to small diameter and culm wall thickness, consequently, influencing their M indirectly. These results suggested that breaking strength was the key factor influencing LI with increase of N fertilizer levels. However, the lodging-related morphology mechanism was different with genotypes. Culm wall thickness and diameter in basal internodes of indica super rice and culm and leaf sheath plumpness status of japonica super rice influenced breaking strength, as well as lodging index, respectively.

IT APPLICATIONS PORTFOLIO MANAGEMENT UNDER BUSINESS AND IMPLEMENTATION UNCERTAINTY

Corporations need to improve business processes in order to enhance velocity and service levels while reducing their processing costs and differentiating themselves in the face of competition. The levitation of importance beyond support roles has raised IT investment decisions to high priority in chief executive officers＇ agendas. Corporate planning groups as well as lines of business are increasingly applying techniques of IT applications portfolio management in a more systematic fashion to improve decision-making and resource-allocation processes. Recent advances in software engineering and IT service delivery methodologies have achieved the logical separation of business functions from implementation. This separation has made a new breed of innovative IT project possible with a new project risk structure; the adjustment of portfolio management techniques is appropriate. We present an integrated portfolio management model so that the corporation can focus on organic growth through sources at both the department and top management levels. The research gives clear advice as to how top management can seek economic growth by selecting an entrepreneurial strategic posture, implying a strong risk-taking propensity. By integrating a risk-return model and risk-tolerance paradigm to cope with today＇s risk structure, overall capabilities can improve the decision process and the corporation＇s performance as well. The application of the integrated technique to a Japanese manufacturing firm is described.

Research on the Role of SCM in China Dairy Firms

In this paper, we investigate supply chain management （SCM） in China dairy industry. The result shows that it can make enterprises cut the expenses and raise the efficiency by implementing of SCM. However, compared with other enterprises which do not implement SCM, those companies which have implemented SCM have not received the anticipated benefit. The reason is that those companies usually implement vertical integration before SCM. This practice normally saves the information cost while increasing the operation cost. it is very difficult to implement SCM system among domestic enterprises that have only business relationship. It is a new subject that the industry faces to implement the SCM by combining each related enterprises of the business together, based on the analysis of vertical integration suiting to enterprise＇s own situation.

Dietary counseling based on artificial intelligence for patients with nonalcoholic fatty liver disease

BACKGROUND About 25%of the general population in Japan are reported to have nonalcoholic fatty liver disease(NAFLD).NAFLD and nonalcoholic steatohepatitis carry a risk of progressing further to hepatocellular carcinoma.The primary treatment for NAFLD is dietary therapy.Dietary counseling plays an essential role in dietary therapy.Although artificial intelligence(AI)-based nutrition management software applications have been developed and put into practical use in recent years,the majority focus on weight loss or muscle strengthening,and no software has been developed for patient use in clinical practice.AIM To examine whether effective dietary counseling is possible using AI-based nutrition management software.METHODS NAFLD patients who had been assessed using an AI-based nutrition management software application(Calomeal)that automatically analyzed images of meals photographed by patients and agreed to receive dietary counseling were given dietary counseling.Blood biochemistry tests were performed before(baseline)and 6 mo after(6M follow-up)dietary counseling.After the dietary counseling,the patients were asked to complete a questionnaire survey.RESULTS A total of 29 patients diagnosed with NAFLD between August 2020 and March 2022 were included.There were significant decreases in liver enzyme and triglyceride levels at the 6M follow-up compared to baseline.The food analysis capability of the AI used by Calomeal in this study was 75.1%.Patient satisfaction with the AIbased dietary counselling was high.CONCLUSION AI-based nutrition management appeared to raise awareness of dietary habits among NAFLD patients.However,it did not directly alleviate the burden of registered dietitians,and improvements are much anticipated.
