Objective: This study aimed to examine the effects of attachment and shared time between mother and child and self-esteem on subjective well-being in late childhood. Methods: A total of 329 fifth and sixth graders in elementary school (183 boys and 146 girls) participated in the study. They responded to questionnaires regarding attachment and shared time between mother and child and the self-esteem and subjective well-being of children. The data were analyzed using SEM. Results: Attachment and shared time between mother and child had an indirect effect through self-esteem as well as a direct effect on the subjective well-being of children. Children who formed secure attachments and spent more time with their mothers showed a higher level of subjective well-being. In addition, when children kept a good relationship with their mother quantitatively as well as qualitatively, they acknowledged their own capability and value positively, which led to higher subjective well-being. Conclusion: Findings emphasize that mother-child relationships play significant roles in predicting both the subjective well-being and self-esteem of children. The importance of self-esteem was identified in late childhood based on its relative influence on subjective well-being compared to mother-child relationships.

The thesis is a comparative analysis of Infill Technologies between Korea's long-life Mock-up House, a study driven by 'Durability and Flexibility of Long-life Housing Technology Development' of R&D, and Japan's KSI experimental house, the major example of Japan's long-llfe housing. In terms of the domestic Mock-up House, a system of building the floor first was applied. The floor material of each housing unit required a development of dry heating component that is partially substitutable in order to avoid conflict with the finishing. Also, a development of a floor system that can counteract against the construction inaccuracy was required. In the Case of an outer wall, need to make the wall with the chassis. In the case of ceiling, need to develop the double ceiling system which is good for sound insulation. Also, in comparison to KSI experimental house in Japan, it would require to develop a wiring system of the ceiling which can react to the movement of the wall. Especially, to assure the flexible nature of an internal wall, it would desperately require the research and development of the products related to components and flexible system of mechanical/electrical/communication parts as well as supporting institutionalized system for this development. Furthermore, for KSI experimental house in Japan, it would be necessary to formulate a construction manual as well as a systematic and practical planning guide to invent a new interface rule which will secure simplicity of assembling, dismantling, installation and replacement of architectural components for which research development is quite insignificant at the moment. This effort will have to continue to give a solid direction for better application of such reference manual during construction and development of long life span apartment by public sector as well as private corporations.

The purpose of this study is to examine the effect of personal psychological variables(cognitive flexibility, emotion dysregulation, subjective health condition), family variables(marital satisfaction, father-adolescent communication) and job satisfaction on the psychological well-being of middle-aged men. For this research, questionnaires were administered to 550 middle-aged men residing in Seoul, Gyeonggi and Incheon. Among 352 questionnaires collected, 327 were selected and statistically analyzed by average, standard deviation, frequency analysis, t-test, one-way ANOVA, and hierarchical regression analysis using SPSS Win 21.0. The main results of the study are as follows: First, according to middle-aged men's social-demographic variables, the level of their psychological well-being differed significantly. Second, cognitive flexibility was the most significant predictor of their psychological well-being. In addition, emotion dysregulation, job satisfaction, father-adolescent communication, and subjective health condition were significant predictors. These results suggest that cognitive reconstruction training or problem-solving intervention could be useful for the psychological well-being of middle-aged men.

In the safety assessment of the geological disposal system of the radioactive wastes, the abnormal scenarios, in which the system is impacted by the abnormal events, need to be considered in addition to the reference scenario. In this study, characterization and prediction of well intrusion as one of the abnormal events which will impact the disposal system were conducted probabilistically and statistically for the safety assessment. The domestic well development data were analyzed, and the prediction methodologies of the well intrusion were suggested with a computation example. From the results, the annual well development rate per unit area in Korea was about 0.8 well/yr/km² in the conservative point of view. Considering the area of the overall disposal system which is about 1.5 km², the annual well development rate within the disposal system could be 1.2 well/yr. That is, it could be expected that more than one well would be installed within the disposal system every year after the institutional management period. From the statistical analysis, the probabilistic distribution of the well depth followed the log-normal distribution with 3.0363 m of mean value and 1.1467 m of standard deviation. This study will be followed by the study about the impacts of the well intrusion on the geological disposal system, and the both studies will contribute to the increased reliability of safety assessment.

The aim of this paper is to develop the ISCOSTFUN (Intelligent System for Prediction of Concrete Strength by Functional Networks) in order to provide in-place strength information of the concrete to facilitate concrete from removal and scheduling for construction. For this purpose, the system is developed using Functional Network (FN) by learning functions instead of weights as in Artificial Neural Networks (ANN). In serial functional network, the functions are trained from enough input-output data and the input for one functional network is the output of the other functional network. Using ISCOSTFUN it is possible to predict early strength as well as 7-day and 28-day strength of concrete. Altogether seven functional networks are used for prediction of strength development. This study shows that ISCOSTFUN using functional network is very efficient for predicting the compressive strength development of concrete and it takes less computer time as compared to well known Back Propagation Neural Network (BPN).

Busan North port is facing crisis due to the opening of the New port. The North Port and NewPort are competing for a limited volume of cargoes and this competition is leading after all to price competition, lowering cargo work fee that may result in the failure of both This paper proposed the balanced development plans, which are the strategies of business tie-up and activation between the North Port and NewPort by introducing the strategy of "co-opetition" and the analysis for the success factor of co-opetition: to solve this operational problems on Busan port. It is found out that activation strategy is more successful co-opetition strategy than business tie-up strategy. The execution for the two co-opetition strategies will lead Busan Port to the balanced development as well as the enhanced competitiveness and will leap Busan port into global hub port as well.

Proper reservoir characterization is an integral part of formation evaluation, reserve estimation and planning of field development. Seismic inversion is a widely employed reservoir characterization tool that provides various rock properties of reservoir intervals. This study presents results of the inversion studies including Geostatistical Inversion carried out on the gas fields, offshore Myanmar. Higher resolution and multiple models can be produced by Geostatistical Inversion using input data such as pre-stack seismic data, well logs, petrophysical relationships and geological inferences for example reservoir shape and lateral extent. Detailed reservoir characterization was required for the development plan of gas fields, and the Geostatistical Inversion studies served as a basis for integrated geological modeling and development well planning.

PPPs in international development cooperation can be challenging due limited capacities in the country, weaknesses in terms of policy and legislative frameworks, differences in mindsets, values, work ethics and hierarchical structures as well as cultural issues. These can lead to misunderstandings and implementation problems. However, a careful assessment of the situation on the ground, stakeholder analysis and needs assessment can help to identify potential bottlenecks and address capacity constraints that could slowdown operations. A sound understanding of local power dynamics and work practices can help to put in place an exit strategy which will enhance the projects' sustainability. Making sure that goals and objectives are understood in the same way by all partners, establishing an ongoing and respectful dialogue between them, as well as transparent implementation and monitoring mechanisms can also contribute to the PPP's success and increase the likeliness to make a difference in the lives of those in needs.
