This study analyzed the feasibility of custom work service to deal with the imbalance of farm labor supply due to population aging. The economic feasibility analysis is based on the case of Bonghwang-myeon in Naju-si, where the majority of farm work is entrusted to local agricultural cooperative. To assess the project profitability and economic feasibility based on the projected cash flow for the next ten years, Return On Investment (ROI), Net Present Value (NPV), and Internal Rate of Return (IRR) of the projects were calculated. The results showed that ROI is estimated at 13.7%, and NPV and IRR are KRW 1,504,932,000 and 15.6%, respectively, with a discount rate of 4.5%, indicating a good enough profitability. Furthermore, a sensitivity analysis with government support as part of an assumption showed that without the support, NPV turns negative, implying that the project is not profitable, and that government support for at least 30% of the cost is needed to secure the economic feasibility of a project. Hence, to promote agricultural work entrustment, it is necessary for the government to partly support the agricultural machinery and facility costs, which require a considerable amount of initial investment.

An early detection system for warranty issues periodically collects customers' claim data and automatically reports alarms about emerging issues based on statistical algorithms. It helps companies to reduce an issue definition time and save the handling cost of warranty claims. This paper provides an evaluation framework to validate the economic effect of an early detection system project. For this purpose, we present economical index of a project with explicit formulas such as ROI(return on investment), PP(payback period), NPV(net present value), PI(profitability index) and IRR(internal rate of return) and analyze the sensitivities of the index according to the variation of project input parameters. The proposed analysis framework is expected to be used for evaluating economic values of various system integration projects.

RFID(Radio Frequency IDentification) is now being applied in the lots of fields as an alternative of barcode system. However, it is restricted within product manufacturing, sales, and delivery parts. In this paper, research results regarding an actual progress of an RFID-based system and its effect are described. In addition, this paper confirms that the RFID-based process of manufacture gives much better return of investment than the barcode-based one. Therefore, the results of this paper are highly expected to contribute to make many people, who might hesitate to replace the barcode and apply RFID system to the process of manufacture, a positive decision.

A computer simulation of biochemical process was carried out using Macintosh-based BioDesignerTM developed at Bioprocess and Engineering Center(BPEC) of MIT. Based on the assumptions and flask culture experiments, a porcine growth hormone (PGH, Porcine Somatotropin) production process was simulated by a two-stage continuous culture. The economical and sensitivity analyses were evaluated for the scale-up production of PGH. A high return on investment (ROI, 104%/year) suggested that the process be profitable. However, sensitivity analysis indicated that ROI was dependent on the yield of PGH, selling price, dose and the achievement of projected market penetration.

An IT system within a company play increasingly important role as a significant part of corporate assets. The IT system possesses an extraordinary ability to improve an organization's efficiency, effectiveness and productivity by providing competitive advantages and improving strategic business decision capabilities. Indeed, providing a more secure IT environment, improving employee productivity and enhancing business process and strategic decision capabilities are key areas to improve corporate performance. However, existing research on IT ROI of return on IT investments does not provide solid justification to stakeholders. In this paper, we analyze the IT investment during the past 28 years from 1982 to 2009 and present the results in two dimensions. First, we show the IT solution implementation analysis by years and industries based on 1,240 IT success cases from 8 different sources such as major Korea IT newspaper, IT magazines, and IT vendors. Then, the paper presents the relationship between IT capability through IT success cases and corporate business performance among 32 industries.

최근 정보보호의 중요성에 대한 인식이 확산되고 있음에도 불구하고 정보보호에 관한 적절한 투자가 이루어지지 않아, 효과적인 정보보호 시스템 구현이 지연되고 있다. 이는 전 세계적인 경제불황이라는 원인도 있겠지만, 정보보호 투자에 대한 정당화 논리가 부족하여 최고 경영자의 의사결정에 적절히 반영되지 않은 이유가 더 크다고 할 수 있다. 정보보호는 조직의 업무 수행에 수반되는 부대비용 개념으로 인식되어 왔으며 이 결과 ROI 와 같은 정보보호 투자에 대 한 정당화 논리를 제공하지 못해 적절한 투자가 적절히 수행되지 못하였다. 따라서 최근에는 정보보호 투자에 대한 수익과 지출간의 관계를 통한 ROSI(Return on Security Investment) 분석을 통한 정당화 논리 전개에 대한 필요성이 대두되고 있다. 본 논문에서는 ROSI 산출에 대한 접근방법을 비교 분석하고 TCO(Total Cost of Ownership)를 이용한 ROSI 방법을 제시하고자 한다. TCO는 하드웨어 가격뿐만 아니라 기술지원 및 유지 지원 인력 등을 모두 고려한 총 소유비용이다. 즉 정보보호에 대한 정확한 총 비용을 구하는데 매우 적합하다고 할 수 있다. 본 연구의 결과는 기업들로 하여금 좀 더 효과적인 정보보호 투자 정당화 수단으로서 활용될 수 있을 것이다.

This study aims to grasp how to understand the difference in return on investment (ROI) or the cost-benefit ratio in forty-two domestic and overseas studies of library valuation, using a meta-analytical review method. Meta-analysis, a quantitative analysis on the findings of previous studies, was conducted to gather the general findings and lessons from prior empirical research. The results of meta-regression analysis indicate that the pattern of findings is consistent with our expectations regarding the effect of benefit scope and per capita GDP included in the ROI figure. This study appears to be the first meta-analytical review conducted on library valuations and the findings provide strong implications for the policy-making process.

최근 들어 보안에 대한 피해의 급증으로 많은 기업들이 정보시스템에 막대한 기업 자원을 투입하고 있다. 뿐만 아니라, 다양한 ROI 평가 방법을 통해 투자대비 최대 수익률을 이끌어 내기 위해 끊임없이 시도하고 있다. 이는 많은 기업들이 정보시스템에 대한 투자를 유보하거나 정확한 평가 및 방법을 내리고 싶어한다는 증거이다. 이러한 기업의 추세는 최근 보안 분야에 있어 합리적인 보안 투자 방침을 세우는데 좋은 지침이 되어 지고 있다. 그러나. 지금의 대규모 정보 시스템 구축 및 웹기반의 인프라 환경에서는 적절한 보안 투자를 한다는 것은 쉽지 않다. 이러한 근본적인 이유 중 하나는 수익률을 측정하는 방법의 부재에서 찾을 수 있다. 따라서, 본 논문에서는 보안 분야에서 쓰이는 기존의 ROSI(Return On Security Investment)모델을 소개하고, 투자의 위험부담을 줄이기 위한 확률 기반의 개선된 ROSI(Probability based ROSI = PROSI) 방법론을 제안하고자 한다.

Maintaining online services of high quality has become a crucial factor for brokerages to gain competitive advantages. Because of the attributes of the product uniformity of online trading, online brokerages have grown significantly with IT development, since the early 2000s. Now, as the online trading business gets mature, the profitability of the IT investment and the quality of IT-based services became questioned. This study examines the issues of IT investment and its contribution by analyzing the relationship between the quality of online service and IT investment. In addition, it also investigates the relationship of the quality of online services and profitability of brokerage. Our results show that IT investment draws cubic-style, curvilinear relationship with the service quality of online trading and only high quality services can lead to the increase of profitability.

This study attempt to use secondary data from KIS-Value to understand how rapid globalization strategy affects BGF's performance defined five categories such as sales volume, return on investment, net profit per employee, increase in sales, and increase in net profit per employee. In particular, this research defines the BGF based on the export ratio within five years after the establishment and classifies BGF into three levels according to 25%, 50%, and 75% concentration of exports. The main results of this study were first, the rapid internationalization strategy was proven to have a sales effect in the short and long term, and in particular, the short term effect was more significantly compared to the long term effect. However, the impact on the return on investment(ROI) of BGF was found that the more stringent the BGF level, the more short-term effect on ROI, but the longer-term effect was diluted according to time. Third, the sales growth rate is significant in the short-term depending on the BGF level, but do not have long-term effects same as ROI. On the other hand, the growth rate of net profit has shown that the BGF strategy has a negative (-) effect over the long term. In particular, the higher the BGF level, the greater the negative impact on the increase in net profit.
