This study investigated the relationships among Selection, Optimization, and Compensation(SOC) as strategies of life management in mid-life crisis respect to gender and age. The subjects of this study were 170 females and 182 males at the ages between 40 and 60 living in Seoul. Selection, Optimization, and Compensation(SOC) as strategies of life management were assessed by SOC-questionnaire while mid-life crisis was assessed by Mid-Life Crisis Scale. The data were analyzed using frequencies, percentiles, means, standard deviations, Cronbach's $\alpha$, two-way ANOVAS, and Pearson's correlations. Except compensation there was no significant difference in Selection and Optimization as strategies of life management as a function of gender and age. No signigicant difference was found in mid-life crisis as a function of gender and age. There were significant negative correlations among Selection, Optimization, and Compensation(SOC) as strategies of life management and mid-life crisis except the individuation.

A time management strategy would reduce the time conflicts from competing time demands of family and business, and contribute to the quality of life of family members in family business. Data were collected on 259 families where one family member was both a household manager and business manager. Household time management strategies and business time management strategies were compared. The individual performing two roles used different time management strategies in household and in business, and they were more likely to use time management strategies in business than in the household. Multiple regression analyses suggested that time management strategy contributed to increased quality of life of dual managers.

Optimal life-cycle management is a challenging issue for deteriorating regional bridges. Due to the complexity of regional bridge structural conditions and a large number of inspection and maintenance actions, decision-makers generally choose traditional passive management strategies. They are less efficiency and cost-effectiveness. This paper suggests a deep reinforcement learning framework employing double-deep Q-networks (DDQNs) to improve the life-cycle management of deteriorating regional bridges to tackle these problems. It could produce optimal maintenance plans considering restrictions to maximize maintenance cost-effectiveness to the greatest extent possible. DDQNs method could handle the problem of the overestimation of Q-values in the Nature DQNs. This study also identifies regional bridge deterioration characteristics and the consequence of scheduled maintenance from years of inspection data. To validate the proposed method, a case study containing hundreds of bridges is used to develop optimal life-cycle management strategies. The optimization solutions recommend fewer replacement actions and prefer preventative repair actions when bridges are damaged or are expected to be damaged. By employing the optimal life-cycle regional maintenance strategies, the conditions of bridges can be controlled to a good level. Compared to the nature DQNs, DDQNs offer an optimized scheme containing fewer low-condition bridges and a more costeffective life-cycle management plan.

The purpose of this study was to investigate the influences of family life cycle stages and perceived time pressure on strategies for coping with time constraints in housewife-teachers. The subjects of this study were 570 married women teachers who live with their husebands and children in junior and senior high schools in Taegu, A questionaire was used as survey method. Factor analysis and MANOVA were employed for data analysis and Scheffe test forpost-hoc analysis. The main findings were : First the effect of family life cycle stages on the use of personal time reducing strategies was different according to perceived time pressure. Second the effect of perceived time pressure on the use of personal time reducing strategies differed according to family life cycle stages. Third the use of strategies for coping with time contratins was found to be significantly different according to family life cycle stages, Forth there were significant differences in the use of strategies for coping with time constrainsts according to perceived time pressure.

This study was conducted to develop and propose a model for an organizational system and management strategies for Healthy Families Centers. As baseline research, the organization of comparable institutions such as the Social Welfare Center, Women's Development Center, Elderly Welfare Center, Child Welfare Center, and Childcare Information Center was analyzed. Based on the results of baseline research and the draft version of Healthy Families Act, this study proposed a management model for Healthy Families Centers. This proposed model suggests the city, county, and district level centers to be organized with three divisions: 1. family counseling team, 2. family education team, and 3. family life team. Concrete assignments for the teams are also proposed. Finally, a networking system for more effective management of the healthy families centers was also proposed.

State transportation agencies utilize fleets of heavy equipment to construct and maintain roadways. Equipment cost models can be developed to forecast economic life, which is the point at which the average unit cost to date reaches a minimum. A calculated economic life and cost models can be used to quantify the impacts of management strategies applied to a fleet. The purpose of this research was to develop an accurate method of quantifying the results of management strategies applied to a fleet of heavy construction equipment. The strategies evaluated are related to the annual usage of the fleet and the size of the fleet. More specifically the methodology is used to adjust the economic model to consider a limit to the annual decline in machine usage and a reduction in the number of machines in the fleet. When limiting annual machine usage, a specified rate is applied to the usage of the fleet, while total usage is held constant. This causes aging at a modified rate. A reduction in fleet size also causes a change to the usage of a fleet as the fleet must use fewer machines to produce the same total usage.

Breaking from the past convention, most construction firms are lotting out their apartments with their own brand names. They don't have, however, differentiated marketing strategies based on unique brand awareness. Rather, virtual absence of marketing strategies has brought about unfiltered introduction of architectural elements of the competition and excessive advertising efforts. Consequently confusion is at hand for consumers' purchase decision since they are not aware of the differences between the apartments. The purpose of this study is to make consumers have clear brand awareness by presenting appropriate brand strategies based on sound marketing theories for construction firms.

The dissemination process of agricultural research and development (R&D) results has somewhat different characteristics from that of typical R&D results. However, these characteristics are not adequately considered on the basis of an examination of the current performance system, the resulting management plans, and strategies for the application and dissemination of the results of agricultural R&D in Korea. The performance evaluation indicator exposed the problem of the inadequate consideration of the characteristics of each of these areas, particularly the lack of unified R&D-related institutions and the inadequacy of the system to monitor outcomes. To address these shortcomings in the agricultural R&D programs in Korea, the policies pertaining to agricultural R&D performance, results management, and dissemination in the U.S. and Japan were examined. Based on these investigations, we proposed strategies to improve the agricultural R&D policies in Korea.

The purpose of this study was to gain an understanding about urban housewives' stress in family financial management, their coping strategies, and their sense of economic well-being, which will eventually provide some baseline data for policy development. The findings of this study are summarized in the following. First, the mean score of the level of financial management-related stress among urban housewives was 2.61 when the maximum level was set at 5. In order to overcome the stress from financial management, housewives utilized various strategies, such as purchasing management, financial planning, financial information gathering, getting a loan, and delaying payments. The average level of economic well-being among urban housewives was 2.82 when the maximum level was 5. Second, among socio-demographic factors, the family's monthly income and the husband's job satisfaction were the two most significant factors that affected the level of financial management stress among housewives. Third, there was a difference in employing coping strategies according to the level of stress. The group with a higher level of financial stress employed more coping strategies than the group with, a lower level of stress. Fourth, there were differences in the level of economic well-being, depending on the types of coping strategies employed. Fifth, the results from regression analyses, which were conducted to determine the relative explanatory power of different independent variable groups including subjective factors, financial management stress, and coping strategies, showed that socio-demographic and objective economic factors significantly affected economic well-being.
