An analysis of Life Cycle Cost (LCC) is to evaluate the system through the total cost accounting during the total life cycle. Railway system has problem that abundant capital has to be utilized efficiently because railway system is a combined system such as power supply, machines, electric signals. Especially, Magnetic Levitation Train needs high technique and more study about the Life Cycle cost by using the system being developed currently in Korea. Therefore, the Modeling of Life Cycle Cost for Magnetic Levitation Train is proposed considering the tendency of the studies in other countries.

Generally, the brand has its life cycle as the product has. This life cycle is classified into the stages; introduction, growth, maturity and decline. Since the brand is little different from that of the product's, we can find some differences when it applies to the brand. The most effective method to perceive the brand to the consumers is advertisement, therefore in the advertisement design, it is important to figure out the current stage in the brand life cycle and use the most ideal design strategy in that stage. This study suggests the concept of the brand life cycle and the most effective strategy in each stages of the advertisement design. In the stage of the brand introduction, we apply the 'What is it? Strategy' which introduces the brand itself. In the stage of the growth, 'How does it Differ from? Strategy' is suggested as the advertisement strategy emphasizing the positioning which shows its differential competitive advantages among brands because in this stage there are many competitive brands in the market. In the stage of the maturity, we focus on the 'What does it Convey of? Strategy' stressing on the delivery of brand's value to consumers as consumers they purchase the brand. Finally in the stage of the decline, 'What does it Stand for? Strategy' is suggested in order to emphasize the generation of brand's symbolical meaning rather than to emphasize it's attributes or benefits. Therefore the advertisement design needs the contingent ideal design strategy according to the stages of brand life cycle and the effective brand management through it.

The purpose of this study is to find methods for logo renewal design according to the brand life cycle, considering the logo as an important visual tool that represents the brand identity in terms of brand management. This study was conducted through literature study on brand life cycle and brand renewal strategy, an expert survey on logo renewal design, and logo analysis of 35 food and beverage brands with statistical data to determine brand life cycle. The results of the study are three. First, the four stages(introduction, growth, maturity, and decline) of brand life cycle characteristics and renewal strategies were derived. Second, four brand renewal strategies(partial change, total change, repositioning, new image creation) and methods for logo renewal design were proposed based on the life cycle of the brand. Based on this, renewal characteristics for each life cycle were proposed. Third, visual elements of identity that are important depending on the brand life cycle and brand renewal strategy were found. It was found that the addition and subtraction of graphic elements and change of color tone are important in the partial change strategy of the growth period and maturity period, and that the change of signature color is important in the repositioning strategy and the creation of the new image.

The purpose of this study investigates the relation between corporate life cycle and management compensation. The analysis is performed by comparing the compensation level and pay-performance-sensitivity (PPS) at each life cycle based on Korean data from 2003 to 2014. The results show that regarding compensation level, mature stage has the highest mean value of compensation and compensation level drops after mature stage. In introduction stage, growth and decline stages, compensation is not sensitive to accounting performance. In a while, in mature stage, management compensation varies with accounting performance more significantly than stock performance. In additional analysis, the results indicate that the finding is not designated from growth opportunities and the relation differs when the firm is included in a conglomerate. These findings contribute to the literature by providing additional evidence to understand for compensation and the corporate life cycle studies.

Engineering structures including civil infrastructures require a life-cycle cost and benefit during their service lives. The service life of a structure can be extended through appropriate inspection and maintenance actions. In general, this service life extension requires more life-cycle cost and cumulative benefit. For this reason, structure managers need to make a rational decision regarding the service life management considering both the cost and benefit simultaneously. In this paper, the probabilistic decision tool to determine the optimal service life based on cost-benefit analysis is presented. This decision tool requires an estimation of the time-dependent effective cost-benefit under uncertainty to formulate the optimization problem. The effective cost-benefit is expressed by the difference between the cumulative benefit and life-cycle cost of a deteriorating structure over time. The objective of the optimization problem is maximizing the effective cost-benefit, and the associated solutions are the optimal service life and maintenance interventions. The decision tool presented in this paper can be applied to any deteriorating engineering structure.

The purpose of this study investigates the relationship between business strategy and cost behavior according to the corporate life cycle. To do so, I first examine the relationship between cost behavior and business strategy. And then, I analyze the effect of the business strategy on cost behavior conditional upon corporate life cycle based on listed Korean firms from 2000 to 2019. Specifically, the business strategy index is calculated by using the six continuous financial factors and the Prospector and Defender was defined on the score. Also, the corporate life cycle is distinguished based on the cash flow pattern. I find the evidence that the Prospector firms are likely to strengthen the asymmetry of cost behavior (cost stickiness), and examined that such a relationship was most strongly represented in the Introduction. This study is meaningful in that this is a more comprehensive analysis by examining business strategy and cost strategy according to the corporate life cycle and expand the application of financial information by using financial indicators to distinguish business strategies.

The purpose of this study is to examine the restructuring strategies that are selected according to the corporate life cycle and to provide evidence that restructuring strategies that are chosen when firms face financial difficulties can have a positive impact on corporate restructuring. This study is logistic regression analysis of 3,593 samples of companies listed on Korea Exchange from 2001 to 2016. The results of this study show that a company that is growing through the expansion of its size and investment can overcome the financial difficulties of the company. And this study finds evidence that the declining firms use the capital increase or debt issuance to revive the corporate regeneration. The results of this study suggest that it is important to consider the life cycle at the time of corporate restructuring and select the appropriate strategy accordingly.

The purpose of this paper is to present a statistical model that can predict the rapid shift of users' attention by analyzing the lifecycle patterns of news in a social news aggregation service. Internet news service sites have a distinct characteristic in a sense that users' attention change very quickly in a short period of time. In this research, we propose a regression model for each news category which can model the decay pattern of users' attention and the content promotion policy of a social news aggregator is proven to be a major source of the rapid growth in the popularity of news. The proposed model is expected to be useful for evaluation of the social news aggregation service provider's content promotion policy that attempts to maximize users' attention as well as the diversity of news contents.
