Infrastructure asset management can be defined as the long term and cost effective management strategy to meet the required service level. In most developed countries, the major motivations of the introduction of asset management are increment in number of assets, extension of maintenance field, accounting approaches of public facilities, performance-based FM(Facility Management), limitations of public funds and public-private partnership, life cycle cost approach, and the development of information technology. This paper discusses the strategic and stepwise methods of introducing infrastructure asset management. Strategic approaches are suggested to develop the practical methods of condition and value assessment of assets, and long-term capital investment plan for optimized decision making(ODM). Required systematic processes are analyzed in terms of resource and technical limitations and detailed implementation plan for each development phases are suggested.

Fashion industry characteristically goes through many steps to manufacture and to retail apparel products. Complex inter-industry channels with many intermediaries in fashion industry provoked many problems regarding recognizing customer's need, delivering time, flexibility, and inventory control. Therefore, the purposes of this study were to investigate the differences between apparel manufacturing and distribution process in SCM success factors and performances, and to investigate how SCM success factors affect on performances. Questionnaire was developed and distributed to apparel industry. The returned 116 questionnaires were analyzed by Cronbach's alpha for internal validity, factor analysis, t-test, and regression analysis with SPSS14.0. The results of this study were as follows: There was significant difference of SCM success factors between apparel manufacturing and distribution regarding process standardization and integration. There were significant differences of SCM performances such as reaction for customer, flexible management, cost minimization, and maximized asset utilization which distribution was higher than apparel manufacturing process. In apparel manufacturing, SC strategic relation, and integrative management influenced upon reaction for customer of SCM performances. SC integrative management influenced upon cost minimization. SC integrative management influenced upon maximized asset utilization. In distribution, SC strategic relation, and activated support for SCM influenced upon reaction for customer of SCM performances. SCM specialization, credible relationship among supply chains, activated support for SCM, and SC integrative management influenced upon cost minimization. SCM specialization, credible relationship among supply chains, and SC integrative management influenced upon maximized asset utilization.

As the social infrastructure becomes deteriorated, its maintenance cost has been increased rapidly. There are growing needs to manage facilities systematically to reduce this kind of maintenance budget, and furthermore to avoid safety accidents in Korea. Asset management is widely used in New Zealand, the United States, Great Britain to manage their social facilities. In these countries, standardized information model and its system are developed and in service for asset management. There are several researches on asset management of social infrastructure in Korea, and the KTAM-40 work procedure is one of the main results for these researches. In this paper, the IIMM of New Zealand and the KTAM-40 of Korea, were surveyed to develop a business architecture of the highway asset management system. A new business architecture for the highway asset management system is proposed based on the KTAM-40 work procedure: First, the organization and its role for the highway asset management are defined. Second, business functions of the highway asset management are classified. Third, the highway asset management functions and the flow of information are defined. In the last section, differences between the newly designed architecture and the other systems' architecture is reviewed.

The purpose of this study is to examine whether suppliers are able to benefit by means of constructing a relationship-specific intangible asset and participating in collaboration with purchasers to actively maintain value created while mutually using inter-organizational information systems. To achieve the purpose of this study. 82 questionnaires have been analyzed from suppliers which are using electronic transactions through inter-organizational information systems. As a result, business process specificity and domain knowledge specificity, which are relationship-specific intangible assets, affect operational collaboration and strategic collaboration, which are classified by level of decision-making. Although both types of collaboration are needed to achieve both strategic and operational benefits, we find each collaboration to be uniquely promoted by a specific types of relationship-specific intangible asset. Operational collaboration is found to be an antecedent to operational benefit and strategic collaboration is found to be an antecedent to strategic benefits. No crossover between collaboration and supplier's benefits is found. Consequently, the result of this study shows collaboration is needed for domestic suppliers, which have relatively low levels of collaboration, to keep maintain relationship-specific intangible assets and to prevent the relationship termination cost when transactions have been stopped between supplier and purchaser. Also the results imply the supplier can have advantages by participating in collaboration.

The study reveals the extent of changes in selective financial numbers caused by fixed asset revaluation (FAR) and explores whether there was a management motive for playing the financial numbers game through using the FAR model. The data set consists of a sample of 142 listed companies purposively selected from 13 industries. The study found a significant impact of FAR on the net asset value (NAV), fixed asset intensity (FAI), and debt-to-equity ratio (DER). These findings are supported by the political cost and the debt covenant hypotheses. The study also observed a high growth of fixed assets by 9.5% to 14,603.8% resulting from FAR. More revealing is that FAR increased NAV in revaluer companies by an average of 427.20% as compared to 6.86% in non-revaluer companies. Even some companies with negative NAV took resort on FAR to show positive NAV. Besides, revaluer companies managed to reduce their DER by 70.45% as opposed to an increase of 8.45% in non-revaluer companies. Hence, the study concludes that most of the publicly-listed companies are involved in financial numbers game by the use of the FAR model. To build confidence among investors, companies should practice FAR rightly and disclose related information to help reduce information asymmetry.

This study provides an evidence on the determinants of the profitability of university hospital by analyzing university hospital-level data set of hospital performance during the year 2007 (32 university hospitals in total). For the study, a multiple regression model is employed in which profitability index obtained from the DEA computations, operating margin to total asset and gross revenue are used as the dependent variables, and a number of hospital operating characteristics are chosen as the independent variables such as ownership type, location, bed size, period of establishment, bed occupancy rate, admission ratio of outpatients, patients per medical specialist, personnel cost per patient, liabilities to total assets, current ratio, fixed ratio, total asset turnover, medical assistance rate and public indicator. First, the results indicate that the bed occupancy rate and liabilities to total assets are positively and significantly associated with operating margin to total asset. Second, number of beds, the bed occupancy rate and number of patients per medical specialist are positively and significantly associated with operating margin to gross revenue. Third, the bed occupancy rate, number of patients per medical specialist, liabilities to total assets, total asset turnover are positively and significantly associated with profitability index revealed from DEA.

The purpose of this research is to analyze the effect of financial elements (asset growth, liability growth, equity growth, revenue growth, and profit growth) on stock price performance and to analyze the growth of Corporate Social Responsibility (CSR) costs as a moderating effect. The technique analysis used is regression analysis. Samples in this analysis are manufacturing firms listed on the Indonesian Stock Exchange (IDX) for the period 2014-2018. The use of regression models for hypothesis testing must fulfill several applicable assumptions such as Normality Test, Heteroscedasticity Test, Multicollinearity Test, Autocorrelation Test, Model Fit Test, Determination Coefficient Test, and Hypothesis Test. Data analysis used two research models, namely model 1 and model 2. Model 1 is without the moderating variable, and model 2 is with the moderating variable, that is, CSR cost growth. Based on the result of the regression analysis, it can be inferred that the asset, revenue, and profit growth have a positive impact on stock price results. Liabilities and equity growth do not affect stock price performance. Operating expense growth has a significant effect on price performance. CSR cost growth can moderate the effect of growth in financial statement elements on stock price performance but is not significant.

Domestic maintenance strategies are shifting from safety assessment to performance assessment, and related systems and laws are being restructured to meet those criteria. In order to introduce asset management based on performance evaluation, related evaluation methods such as performance measures and level of service should be made to evaluate performance according to the characteristics of the structure, but these are not well-prepared in Korea. In this study, we present a computerized model and system for implementing asset management that introduces techniques such as performance evaluation, life cycle cost analysis, performance measures, and level of service in conjunction with existing maintenance and safety diagnosis procedures. The features of this system consist of three modules to enable separate operations of existing maintenance, safety management and asset management. The system is designed to be used as a reference for public institutions to introduce asset management in the future.
