Construction contactors must continuously seek to improve their cash flows, which reside at the heart of their financial success. They require careful planning, analysis, and optimization to avoid the risk of bankruptcy, remain profitable, and secure long-term growth. Sources of cash include bank loans and retained earnings, which are conceptually similar in that they both incur a cost of capital. Financial management therefore requires accurate yet customizable modeling capabilities that can quantify all expenses, including said cost of capital. However, currently existing cash flow models in construction engineering and management have strongly simplified the manner in which interest is assessed, which may even lead to overstating it at a disadvantage to contractors. The variable nature of cash balances, especially in the early phases of construction projects, contribute to this challenging issue. This research therefore extends a new cash flow model with an accurate interest calculation. It utilizes singularity functions, so called because of their ability to flexibly model changes across any number of different ranges. The interest function is continuous for activity costs of any duration and allows the realistic case that activities may begin between integer time periods, which are often calendar months. Such fractional interest calculation has hitherto been lacking from the literature. It also provides insights into the self-referential behavior of compound interest for variable cash balances. The contribution of this study is twofold; augmenting the corpus of financial analysis theory with a new interest formula, whose strengths include its generic nature and that it can be evaluated at any fractional value of time, and providing construction managers with a tool to help improve and fine-tune the financial performance of their projects.

The purpose of this study is to examine the influence of expected values for appearance management on interest in make-up and cosmetics evaluation criteria. Questionnaires are being administered to 244 college students from the Deagu Metropolitan City and Kyungbook province. The frequency, factor analysis, reliability analysis, regression analysis, and t-test are used for data analysis. Expected values of appearance management are categorized into pleasure/satisfaction, other-expectancy, power value and conformity. Interest in make-up factors are found to be leadership in make-up, others-oriented, and appearance satisfactions. Cosmetics evaluation criteria are categorized into 4 factors such as skin suitability, pursuit of utility, non-essential attributes and symbolism. Pleasure/satisfaction, and conformity are the sub-variables of expected values for appearance management and have significant effects on leadership in make-up and others-oriented sub-variables for interest in make-up. Pleasure/satisfaction, and conformity, being the sub-variables of expected values for appearance management, have significant effects on skin suitability, the sub-variables of cosmetics evaluation criteria. And conformity has significant effects on symbolism, the sub-variables of cosmetics evaluation criteria. This indicates that women show high conformity for expected values of appearance management, leadership in make-up and others-oriented sub-variables for interest in make-up, and skin suitability of cosmetics evaluation criteria.

Artifical Neural Network(ANN) models were used for forecasting interest rate as a new methodology, which has proven itself successful in financial domain. This research intended to construct ANN models which can maximize the performance of prediction, regarding Corporate Bond Yield (CBY) as interest rate. Synergistic Market Analysis (SMA) was applied to the construction of models [Freedman et al.]. In this aspect, while the models which consist of only time series data for corporate bond yield were devloped, the other models generated through conjunction and reorganization of fundamental variables and market variables were developed. Every model was constructed to predict 1,6, and 12 months after and we obtained 9 ANN models for interest rate forecasting. Multi-layer perceptron networks using backpropagation algorithm showed good performance in the prediction for 1 and 6 months after.

Social interest in disasters is a significant factor in shaping disaster management policies, enabling the enhancement of disaster safety management and prevention activities according to the specific needs of society. However, in the past, there were limits to measuring which disasters society was particularly interested in. Hence, in this study, a method of measuring social interest using news data was devised. Specifically, we classifed news reports into natural and social disasters, creating a comprehensive Social Interest Index (SII) on disasters covering from 2011 to 2021. Additionally, we quantitatively compared the SII with budgets allocated to disaster-related efforts. Our primary findings are as follows: First, our methodology not only distinguishes natural disasters from social disasters but also identifies emerging areas of societal concern. Second, in recent years (2014-2021), social disasters gained more attention than natural disasters. Third, the disaster safety budget accounted for approximately 3.5% of Korea's total budget, closely paralleling the SII we measured. However, exceptions were noted in cases such as heavy snow, cold waves, and heat waves, where the SII remained high, but the disaster safety budget was relatively low, indicating potential outliers. The findings of this research are projected to contribute to the improvement of national disaster management policies by providing a quantitative measure of social interest in disaster, enabling more informed and effective policy decisions.

The purpose of this paper is to present a neural network model based on change-point detection for the prediction of the U.S. Treasury Securities. Interest rates have been studied by a number of researchers since they strongly affect other economic and financial parameters. Contrary to other chaotic financial data, the movement of interest rates has a series of change points due to the monetary policy of the U.S. government. The basic concept of this proposed model is to obtain intervals divided by change points, to identify them as change-point groups, and to use them in interest rates forecasting. The proposed model consists of three stages. The first stage is to detect successive change points in the interest rates dataset. The second stage is to forecast the change-point group with the backpropagation neural network (BPN). The final stage is to forecast the output with BPN. This study then examines the predictability of the integrated neural network model for interest rates forecasting using change-point detection.

The developments of consumption culture and mass media have caused consumers to take a greater interest in appearance, and as a result, the appearance related industry has been rapidly developed. Since appearance serves as a means to attain a smooth and successful social life, women invest a lot of time in cultivating their appearance more prominently than others and are more agreeable to the criteria of beauty in society. This study is to analyze the degree of satisfaction of appearance in teens to women in their 50s as classified by their lifestyle. For the data analysis, the statistical program, SPSS WIN 14.0 was used. First, the results of examining the degree of interest in appearance, the degree of bodily satisfaction, and the degree of bodily importance showed that the interest in appearance was highest in the fashion pursuing group. The degree of bodily importance was highest in the economy-oriented group. Second, appearance management attitudes showed significant differences m hair attitudes, makeup attitudes, skin attitudes, face-lifting attitudes, and clothing attitudes, depending on the types of lifestyle. Third, it could be seen that the conservative-oriented groups were doing more skin care management than the other groups.

It is important to find the equilibrium level of real interest rate for it affects real and financial sector of economy. However, it is difficult to find the equilibrium level because like the most macroeconomic model the real interest model has parameter instability problem caused by structural change and it is supported by various theories and definitions. Hence, in order to cover these problems structural change detection model of real interest rate is developed to combine the real interest rate equilibrium model and the procedure to detect structural change points. 3 equations are established to find various effects of other interest-related macroeconomic variables and from each equation, structural changes are found. Those structural change points are consistent with common expectation. Oil Crisis (December, 1987), the starting point of Economic Stabilization Policy (January, 1982), the starting point of capital liberalization (January, 1988), the starting and finishing points of Interest deregulation (January, 1992 and December, 1994), Foreign Exchange Crisis (December, 1977) are detected as important points. From the equation of fisher and real effects, real interest rate level is estimated as 4.09% (October, 1988) and dependent on the underlying model, it is estimated as 0%∼13.56% (October, 1988), so it varies so much. It is expected that this result is connected to the large scale simultaneous equations to detect the parameter instability in real time, so induces the flexible economic policies.
