  • Indonesia has become a net crude oil importer because of the reduction of a new oil field discovery, and Indonesia is attempting to raise investment funds through the Kerja Sama Operasi (KSO) contract to develop a small-scale field. However, the KSO has a high-risk and low-return contract system for investors, necessitating an economic evaluation to examine the feasibility of the project. This study performed economic evaluation on the development of an Indonesian small-scale field by applying the KSO contract conditions, and identified the major economic parameters through a sensitivity analysis. As a result, the oil price, CAPEX and OPEX were identified as influential factors for economic evaluation. The results also indicate that commercial production in small-scale fields is difficult. In the future, this study can be used as a reference resource for investment in oil and gas development projects in Indonesia.

  • This paper presents an integrated strategy to produce cellulosic ${\gamma}$-Valerolactone (GVL) using lignin derived propyl guaiacol (PG) from lignocellulosic biomass. A commercially large-scale process that was designed based on the strategy achieves 12.3% carbon yields at low (9.1-30.0 wt%) concentrations of reactants, and requires an efficient separation system to obtain high recovery of products with low energy requirements. A heat exchanger network is designed to significantly decrease the total energy requirements of the process. Techno-economic evaluation results assuming nth commercial plant and negative economic parameters show that this process ($US 3,805/t GVL) can be cost-competitive with current production approaches.

  • Reducing global warming potential has become important, and as one of those methods for reducing it, economic evaluation by applying ice thermal storage air conditioning system was performed. The floor area and height of the subject building was assumed $5,000m^2$ and 20 m. Absorption chillerheater system and air source heat pump system was used for comparing to the subject system, and payback period method was used to perform economic evaluation. Although the running cost of ice thermal storage system is reduced compared to two systems, the ratio is not significant compared to the increase of initial construction expenses, and payback period was calculated to be about 7.7 and 79.3 years. However, the heat storage system should be approached from the viewpoint of long term rather than the economic standard in the present standard.

  • The economic effects of informatization are differently occurred according to industry types. Thus an evaluation methodology which reflects the industry type characteristics of informatization is needed. In this paper, we develop and analyze the indices for evaluating economic effects through informatization according to industry types, such as manufacturing, construction, financial services and marketing services. The factors related to performance of enterprise informatization can be defined as cost factors, effect factors, risk factors and influence factors. Effect factors are defined as quantitative or qualitative performance of informatization and classified into operational effect factors and strategic effect factors. The influence factor is defined as characteristics of informatization for industry types, that is, value chain of business and business products or services. Economic effect indices are classified according to the activity of business value chain. Economic effects indices of this research can be expected to play a role of general and standardized factors for economic evaluation of industry informatization.

  • The demand for pharmaco-economic data has increased since the introduction of positive list system for drug insurance. A survey was conducted for pharmaceutical companies, universities and hospitals to find the current states and barriers for pharmaco-economic studies in Korea. The results showed that even those who are in charge of pharmaco-economic studies at companies/universities had a limited technical expertise. Government should pay more attention to the education of the relevant manpower, and the production of national statistics needed for economic evaluation.

  • Fashion companies confront to environmental problem and resource depletion and have to consider 'sustainability' into their management. Corporate sustainable management of company is explained as the model of Triple Bottom Line which is composed of economic, social and environmental elements, thus we wanted to adapt this model to the case of fashion companies and the purpose of this study is to investigate the relationship among the TBL elements which contain the economic, social and environmental responsibility, the evaluation on fashion company including the reliability, reciprocality and reputation of company, and the evaluation of brand image. We conducted the survey of questionnaire about 300 people in their 20's and performed statistical analysis. As a result, the elements of corporate sustainable management in fashion company are related to the company evaluation, and again company evaluation is correlated to the evaluation of brand image. Economic responsibility of fashion company is related with the reliability of company evaluation, social responsibility of fashion company with the reciprocality and reputation of company evaluation, and environmental responsibility is deeply related with reciprocality of fashion company's evaluation. The results of this study revealed the importance of corporate sustainable management of fashion companies, and the relationships in fashion industry are stronger than in other industry.

  • Recently, regulation on carbon emissions has been strengthened according to the new climate change convention (COP21) held in Paris, and then Korea has decided to reduce CO2 emissions by 37% until 2030. As one of countermeasures, the government has energetically performed demonstration projects of island micro-grid including solar power, wind power and energy storage system. However, in order to smoothly introduce island micro-grid, it is a critical issue to carry out the economic evaluation for power utility aspect and independent power producer aspect. Therefore, this paper proposes economic evaluation algorithms of island micro-grid which are based on the present worth method, considering cost and benefit factors in the aspect of both sides. Firstly, in case of power utility this paper proposes algorithm to estimate a period of return on investment according to the introduction capacity of distributed generators replacing diesel generator. And also, in case of independent power producer, this paper proposes evaluation algorithm to estimate weighting factor of SMP and benefit rate based on break-even point related with cost and benefit. From a case study result on real island micro-grid model, it is confirmed that proposed algorithms are useful and practical for the economic evaluation of island micro-grid.

  • Despite the eco-friendly route plan, road slopes were collapsed due to road construction, resulting in human and property damage. To solve this problem, the Ministry of Land, Transport and Maritime Affairs established guidelines in 2009 to conduct a test-bed for slope recording considering the conditions of the site and the ecological environment, and divided them into recording quality and economic evaluation. The following results were obtained by analyzing 183 construction methods of cut-soil sections at 60 sites from 2012 to 2018 for road slope afforestation research. Straw net+seedspray, vegetation media spray method 1T, 3T were used the most, and vegetation media spray method 3T(patent) was excellent in quality, and straw net+seedspray was excellent in economics. As a result of analyzing the market unit price and the construction unit price, vegetation media spray method submitted the construction unit price at up to 60% lower than the market unit price. As a result of the analysis of the key factors of the greening method evaluation, the economic assessment had the greatest influence on all evaluation items. Problems in the evaluation method of revegetation were first identified as problems in the allocation of points and secondly as problems in the evaluation criteria. As for the improvement of the economic assessment criteria, the method was proposed to evaluate the same method based on market unit price when the same method was constructed, and not to conduct an economic assessment if there was a difference in market unit price between methods, or to add weight to the scores. Based on the monitoring data of 60 road slopes, this study drew up problems and improvement measures. However, with regard to scoring, research on appropriate scoring is needed by examining the current status.
