Purpose - This study investigates the performance of investment strategies incorporating estimated stock market cycle based on a lead-lag relationship between business cycle and stock market cycle, thereby deriving empirical implications on risk management. Design/methodology/approach - The data period ranges from June 1953 to September 2022 and de-trended short rate, term spread, credit spread, stock market volatility are considered as major input variables to estimate business cycle and stock market cycle by applying probit model. Based on the estimated stock market cycle, two types of strategies are constructed and their performance relative to the benchmark is empirically examined. Findings Two types of strategies based on stock market cycle are considered: The first strategy is to long(short) on stocks when stock market stage is expected to be an expansion(a recession), and the second one is to long on stocks(bonds) when expecting an expansion(a recession). The empirical results show that the strategies based on stock market cycle outperforms a simple buy and hold strategy in both in-sample and out-of-sample investigation. Also the out-of-sample evidence suggests that the second strategy which is in line with asset allocation is more profitable than the first one. Research implications or Originality The strategies considered in this study are based on the estimated stock market cycle which only depends on a few easily available financial variables, thereby making easier to establish such a strategy. It implies that investors enhance investment performance by constructing a relatively simple trading strategies if they set their position on stocks or choose which asset class to buy conditioning on stock market cycle.

This study investigates the effects of parent-adolescent communication, adolescent self-esteem, and strategies in peer conflict situations on the satisfaction of adolescents with their peer relationships. The subjects included students attending a girls' and a boys' middle school in Gongju City. Random sampling was used to pick a class from each of the three grades in the schools. 233 students, who's both parents were living, were used in the final analysis in an effort to examine the impacts of student communication with parents on student satisfaction with their friends. The findings were as follows: the subjects most often used the yielding type of conflict-resolving strategy, followed by the cooperating, compromising, dominating, and avoiding strategy-type. The girls showed a higher level of parent-child communication than the boys. Girls had high self-esteem and mostly adopted the cooperating type of conflict-resolving strategies, followed by the yielding, compromising, dominating and avoiding strategy-type. The boys mostly employed the yielding strategy type followed by the cooperating, compromising, dominating, and avoiding strategy-types. The results indicate that the satisfaction level with friends was high among those who used the avoiding strategy-type less and yielding strategy-type more. Girls were found to have high self-esteem and engaged in communication with their parents. The compromising, cooperating, and dominating types of conflict-resolving strategies did not exercise significant influences on their satisfaction with friends.

The proportions of both the fishery industry and the gross regional domestic product in the national economy are gradually decreasing. If high value-added processed fishery products suitable for regional characteristics are developed, these proportions can be improved. In pursuit of this, it is first necessary to discover processed fishery products specialized in each region and then establish a development framework for them. In this study, location coefficient was used to find processed fishery products specialized in each region. Then, dynamic shift-share analysis was used to establish a development framework which consisted of four development types of processed fishery products. Based on the magnitudes of the industrial mix effect and the regional shift effect, the supporting strategy directions were proposed for four development types of processed fishery products. The supporting strategy directions were all focused on revitalizing the local economy.

The purpose of this study is to segment the mobile phone users based on the flow types and to understand the differences in mobile phone usage behavior between the segmented groups. The 'flow' construct, which was introduced first in marketing by Hoffman and Novak[44], has been used as an important keyword for understanding consumer behavior on the World Wide Web. In this paper, we will try to use the flow aspect for the mobile market segmentation, which is one of the most fundamental tools for developing a successful marketing strategy on the mobile phone service market. We collected survey data from consumers and analyzed the data with the SPSS 12.0 package where we did ${\chi}^2$-test, factor analysis, one-way ANOVA and cluster analysis. Main results of this study are as follow. First, the flow types of the mobile phone users were classified into five types, which are named as the 'Flow' type, 'Apathy' type, 'Anxiety' type, 'Boredom' type, 'Control' type. Second, most of the results related to the usage of mobile phone service showed statistically significant differences between flow types. These findings suggest that the mobile phone service marketers should consider the various flow types of users and work out effective market segmentation strategies based on these consumer flow types.

Based on the usage levels of target costing systems(TCS) and information technology (IT) infrastructure, this study aims to develop a framework useful for classifying four types of knowledge management(KM) strategies in manufacturing firms: process-oriented, product-oriented, mixed and negative. We adopted a multi-methodological approach by mixing both qualitative and quantitative methods. Before developing a framework, through a case study of the H Motor Company in Korea, this paper investigated and showed the functions of TCS in the management of tacit knowledge. The results from the case study indicated that with the use of TCS, a firm can create, transfer, and share diverse kinds of tacit knowledge among employees for the facilitation of process innovation. We also empirically confirmed the four types of KM strategies, and demonstrated the characteristics(i.e., size, total sales, age, and knowledge intensity) of the organizations adopting each strategy.
