Recently, the need for asset management(AM) plan introduction to reduce increasing O&M cost with aging water facilities is on the rise. Therefore, asset inventory classification is necessary as the first step for AM plan construction. In this study, all assets of YW water treatment plant(WTP) were classified as 5 steps. In addition, specific code name was given to each asset which can increase compatibility in constructing the AM programs among WTPs. In the future, codes for attribute and status of asset will be allocated, which can facilitate proper AM operation.

In this study, we present a fast option pricing method for four asset equity-linked securities (ELS) using Brownian bridge. The proposed method is based on Monte Carlo simulation (MCS) and a Brownian bridge approach. Currently, three asset ELS is the most popular ELS among multi-asset ELSs. However, four asset ELS emerged as an alternative to three asset ELS under low interest rate environment to give higher coupon rate to investors. We describe in detail the computational solution algorithm for the four underlying asset step-down ELS. The numerical tests confirm the accuracy and speed of the method.

This paper examines the relationship between diversification and financial performance of community credit unions in Korea from 2011 to 2017. To do so, I employ fixed-effects panel analyses using credit union level panel data collected from the National Credit Union Federation of Korea. This study finds evidence that business diversification is likely to lower the ratio of troubled loans, which means improving asset quality of credit unions. However, the relationship between diversification and asset quality is not linear but nonlinear, which means over-diversification would have negative effects on asset quality. Next, diversification tends to increase profitability. Specifically, although diversification results in a rise in expenditures, an increase in profits made by diversification outweighs the rise in expenditures, which contributes to profitability. Put together, diversification would be a good business strategy to improve both profitability and asset quality. Given a result that fast loan growth deteriorates asset quality, credit unions' managers might adopt the diversification strategy to enhance asset quality, and not to pursue their own objectives motivated by moral hazards.

This paper discusses cases of infrastructure asset management in the U.S., Canada, and Australia and investigates infrastructure management in Korea in order to set the direction for the asset management improvement. The definitions of infrastructure asset management from various entities are introduced and implementation framework and organizational structures are described. The investigation on Korean public asset management practices finds the strong and weak points and defines the requirements and considerations to further improve the current practices. This paper will assist adopting infrastructure asset management in Korea and provide guide for the infrastructure maintenance.

We define some multi-type asset models derved from L$\acute{e}$vy proceses which emphasize coefficients of stochastic differential equations. Also these asset models can be represented by Doleance-Dade linear equations derived from jump-type semimartingales which are decomposed by various terms of time basically. For these asset models, we can construct optimal portfolio strategy by using filtered various information at each check time.

We analyze some real data and, from the background of analysis of data, we define a multi-dimensional jump-type asset model which is derived from short-sampling asset prices. We study some basic properties of this asset model.

This study analyzed the household portfolio according to wealth levels using a survey data of 1997 Korea Household Panel Study. The major findings of this study are as follows: (1) A household in high wealth level has invested relatively large proportion of his asset into real estate (2) A household in middle wealth level has invested relatively large proportion of his asset into risky financial asset(3) A household in low wealth level has invested relatively large proportion of his asset into secure financial asset. These findings accorded with risky pyramid model.

"측정할 수 없는 것은 관리할 수 없다"는 말은 성과측정 시스템의 중요성을 잘 나타내 주는 말이다. 또한 이처럼 어려움을 나타내는 표현도 없다. 기업의 유형자산은 재무제표나 손익계산서 등의 구체적인 금액으로 측정이 가능하나 기업의 무형자산에 대한 가치측정은 많은 방법들이 도입되어 왔지만 어느 하나도 객관적인 틀을 제시하지 못하고 있다. 이에 본 연구는 LG경제연구원에서 제시한 지식자산 축적모형(XYZ모형)을 통하여 건설기업의 무형자산(지적자산)의 크기를 객관적으로 정량화 시키었다. 이를 통하여 현 건설기업의 내재가치 수준을 추정할 수 있다.

최근 들어 건설기업들은 경쟁적으로 주택 브랜드들을 개발하여 활발한 브랜드 마케팅 투자를 하고 있다. 브랜드 자산의 중요성은 현실적으로 증대되고 있으며, 강한 브랜드를 만들기 위해서는 브랜드 관리가 전재되어야 하는 시기이다. 하지만 지금까지의 브랜드 자산 관리는 주로 제조업이나 서비스업의 제품들을 대상으로 이루어지고 있으며, 건설기업들의 주택 브랜드 자산 관리에 관한 논의는 미비하다. 브랜드 자산의 중요성을 인식하면서도 주택 브랜드 자산 관리 방법의 부재로 인해 브랜드 마케팅 투자의 지표가 되는 근거를 제시하지 못하고 있는 실정이다. 따라서 본 연구에서는 브랜드 파워 조사를 통해 자산 구성 요소별 중요도를 산출하고, 이를 바탕으로 주택 브랜드 관리 전략에 관한 기반을 제공하고자 한다.
