Purpose: This study was done to review Taegyo types, the practice of Taegyo, factors of Taegyo, and the effect of Taegyo programs in Korea. Method: This study reviewed the preceding research related to Taegyo through websites, articles, and books. Result: As a result of a review of Taegyo types, the practice of Taegyo, factors of Taegyo, and the effect of Taegyo programs through websites, articles, and books, it was summarized that pregnant women were independent people able to practice Taegyo from pre-pregnancy to childbirth for baby's health. If she practiced encouraging behaviors of Taegyo with her husband's physical, emotional, and economical support, she and her husband would easily transition to parenthood and form strong attachments with their baby. In addition, the rate of mother's postpartum depression was decreased. However, some pregnant women felt a psychological, social, and economical pressure to practice Taegyo. Conclusion: Activating organized and accessible to support systems and community networks, such as community health centers, nurses can help pregnant couples to increase self-care through the performance of Taegyo.

The purpose of this study was to assess risk indicators of depressive symptoms such as demographic, socio-economical domains (age, gender, marital status, education, child, religion, income, health, friendship) and personality domains (neurotic personality, self-esteem and life goal attitude) of community dwelling elderly persons. A total of 300 community-residing elderly participants aged 65+ in a metropolitan city in Korea, were recruited for this interview survey. The interview covered demographic and socio-economic characteristics, and administration of the 20-item Korean Version of CES-D, the 10-item Self-esteem, the 19-item Neuroticism and the 10-itm Goal Instability scale. The prevalence of significant depressive symptoms (CES-D scale >= 21) was 31%. Logistic regression analysis showed high risk for depression was associated with high neuroticism, less intimate friendship, high goa1 instability, and childlessness, respectively in the order of significance. Factors in the personality domains were more strongly associated with depressive symptoms than factors in the socio- economical domains. Both cultural and universal meaning of the findings was discussed with regard to intervention.

Before expanding of distribution automation application to distribution network, we must examine whether there are economical effect. Investment expense for distribution automation can be divided into facility investment expense, maintenance expense, communication expense, investment expense etc. Effect of distribution automation can classify by effect that can convert into money and effect that can not convert into money. Representative effect is outage time decrease effect, distribution line loss decrease effect, main transformer upload effect, distribution line upload effect, work environment improvement effect of lineman and so on. This paper studied economical effect and break-even Point for investment expense by using data that acquire in KEPCO's distribution network.

In operation of distribution system, $DG_s$ Distributed Generations) are installed as an alternative of extension and establishment of substations and transmission and distribution lines according to increasing power demand. In operation planning of $DG_s$, determining optimal capacity and allocation gets economical pro(it and improves power reliability. This paper proposes determining a optimal number, size and allocation of $DG_s$ needed to minimize operation cost of distribution system. Capacity of $DG_s$ (or economical operation of distribution system estimated by the load growth and line capacity during operation planning duration, DG allocations are determined to minimize total cost with power buying cost. operation cost of DG, loss cost and outage cost using GA(Genetic Algorithm).

Recently, the chaotic method is employed to forecast a near future of uncertain phenomena. This method makes it possible by restructuring an attractor of given time-series data in multi-dimensional space through Takens' embedding theory. However, many economical time-series data are not sufficiently chaotic. In other words, it is hard to forecast the future trend of such economical data on the basis of chaotic theory. In this paper, time-series data are divided into wave components using wavelet transform. It is shown that some divided components of time-series data show much more chaotic in the sense of correlation dimension than the original time-series data. The highly chaotic nature of the divided component enables us to precisely forecast the value or the movement of the time-series data in near future. The up and down movement of TOPICS value is shown so highly predicted by this method as 70％.

In this thesis, the study on controlling of cracks of concrete box culvert in early ages is presented. The optimum construction method and economical analysis were proposed also through the experiment of the material and field test. As a result of the experiment of the material, using fly ash, CSA expansive agent and BELITE cement(type IV) showed good result in the control of cracks induced by heat of hydration and shrinkage. As a result of construction test analysis, the maintenance time of form system did not show a big difference in controlling of cracks. Control of distribution of reinforcement, spacing of expansion joint and use of BELITE cement showed big differences in the control of cracks in early ages. As a result of economical analysis, control of construction variables before construction can make it possible to reduce the repair expense.

The existing methods for installation of long steel pipe pile have some uneconomical problems such as increase of installation cost and period due to the welding of two piles and removal of soil plug, and decrease of driving efficiency due to the increase of driving resistance by time effect during the welding of piles and removal of soil plug, etc. Thus, in this study, new installation method for long steel pipe pile is suggested to work out the existing problems, and calibration chamber tests are peformed to investigate both driving and economical efficiency for the suggested method. The test results showed that the new installation method has increase bearing capacity as well as reduce installation cost and period for long steel pipe piles as compared with existing methods.

After 1980's, the progress in quantities of apartments were made by the housing construction expediting policies. But, the qualities of apartments were neglected and the plan of apartments were uniformed by the economical aspects. Apartment unit plans were designed standardized by the reasons of economical efficiency, structural methods and sales. Therefore apartments could not deal effectively with increasing demands for qualities of the residents. Absence of aesthetical values and fixed unit plans on regardless of the residents family compositions and the size of the apartments were occurred. So the new types of the apartment plans are needed to suit the changes and diversities of living. The purpose of this study is to extract the design factors for future apartment by analyzing the unit plans of apartment housings today.

In 2007, Seoul Metropolitan Government introduced new public rental housing policy called SHift that works as rental deposit base. The purpose of this study is to evaluate the residential satisfaction of SHift. This research has shown conclusively that there is a link between the Location of apartment, Internal Premises, External Premises and satisfaction of SHift residents. The main factors of Residential satisfaction of SHift residents are Location of economical factor. The factor analysis of the 12 factors of variable are confirmed by the internal consistency reliability. This analysis is evaluate on discrimination of the correlation between the dwelling circumstance and the residential satisfaction. The economical factor was the main factor among the Independent variables. It can be concluded that the general overview of the Residential Satisfaction of SHift residents satisfaction is "quite good". But there are maby problems on SHift.
