The outbreak of COVID-19 has significantly impacted various facets of individuals' lives, including perceptions, leisure activities, work-family balance, and overall life satisfaction. This study aims to explore the intricate relationships among changes in perceptions due to COVID-19, leisure activity satisfaction, work-family conflict, and life satisfaction of married working women. Employing path analysis, we examined a dataset of 1,973 married working women drawn from the 8th Korean Women and Families Panel Survey. The findings indicate that while changes in perception associated with COVID-19 did not directly affect leisure activity satisfaction and life satisfaction, they did significantly decrease work-family conflict, indirectly leading to heightened life satisfaction. Additionally, leisure activity satisfaction emerged as a mitigating factor for work-family conflict, contributing to enhanced life satisfaction. These results emphasize the importance of understanding the interplay between external factors, individual perceptions, and well-being, offering insights for devising tailored strategies. The study holds significance in guiding policies and interventions to enhance the quality of life for married working women in the context of evolving pandemic challenges.

A web-based program life-cycle management(PLM) system is introduced to implement the system engineering processes and to provide the development teaceability online. This information system aims for the realization of essential system engineering management techniques currently applied to the space launch system development program including management of configuration and data based on the work breakdown structure(WBS), WBS, bill of materials and properties. The system enhances communication and gives access to the development data with relevant information such as data-to-data relation and approval status/history through the web, and preserve all of the development data throughout the program life-cycle. Further improvement of the system is planned to implement the program managrment pricesses and to provide integrated information useful for the programmatic decision making.

Reinforcement corrosion is one of the major problems in the durability of reinforced concrete structures exposed to aggressive environments. Deterioration caused by reinforcement corrosion reduces the durability and the safety margin of concrete structures, causing excessive costs in managing these structures safely. This paper aims to investigate the effects of reinforcement corrosion on the load bearing capacity deterioration of the corroded reinforced concrete structures. A new analytical method is proposed to predict the crack growth of cover concrete and evaluate the residual strength of concrete structures with corroded reinforcement failing in bond. The structural performance indicators, such as concrete crack growth and flexural strength deterioration rate, are assumed to be a stochastic process for lifetime distribution modelling of structural performance deterioration over time during the life cycle. The Weibull life evolution model is employed for analysing lifetime reliability and estimating remaining useful life of the corroded concrete structures. The results for the worked example show that the proposed approach can provide a reliable method for lifetime performance assessment of the corroded reinforced concrete structures.

In modern society, dementia patients are increasing due to busy daily life. Due to the nature of dementia, family members are having a hard time with their caring activities. Dementia diseases reduce the quality of life not only of the patient, but also of the family, and nursing activities lead to social problems such as unemployment or frequent turnover. This study aims to reduce the difficulty and stress of the nursing process by supporting daily life of dementia patients and nursing activities through smart care platform. Ultimately, we will reduce the cost of treatment for people with dementia and delay the worsening of symptoms through a systematic care program for people with dementia. The smart dementia care platform features smart technology to help the dementia patients' daily lives and support their caregivers.

The study aims at analyzing practices of vocational life of human resources in Busan. This study adopted a questionnaire method in research of university(14), college(12) and public & private vocational training institute(10) in Busan areas for empirical analysis. Analyzing items are consist of two parts. The one is employment life and job-seeking activity, the other is career development and future plan in career. The major findings of this study are summarized as follows. First, employees have had a 2-3 times job transfer experiences. Second, difficulties of job-seeking activity are lack of information and experience. Third, the best wanted region for job transfer is Seoul etc.

Life Cycle Assessment (LCA) aims to analyze possible impact upon manufacturing process and availability of products, and also study the environmental considerations and potential influence during entire life cycle ranging from procurement, production and utilization to treatment (namely, from cradle to tomb). Based on high-density polyethylene (HDPE) pipe manufacturing of company A, this case study would involve evaluation of environmental influence during the production process. When the manufacturing process has been improved during "production process" and "forming cooling" stage, it is found that capital input on "electric power" and "water supply" could be reduced, thus helping to sharpen the competitive power of company A, and also ensure sustainable economic and industrial development in accordance with national policies on environmental protection.

This study analyzed the aims, contents, and methods of early education in Sohak(小學) a textbook for childhood education in the choson Dynasty. The analysis was based on the 6th Korean National Kindergarten Curriculum(in process) and the theories of education in Sohak. Sohak consists of Establishing the Education Process(入敎), Clarifying the Cardinal Human Relationships(明倫), Reverencing for the Self(敬身), Examining Antiquity(稽古), Admirable Sayings(嘉言), and Exemplary Deeds(善行). The aim of education in Sohak was to preserve Sheng(性), i.e. human nature inherited from heaven. The contents of education in Sohak was divided into 6 groups: distinction by age and sex, health, basic life habits, private life, family life, and group life. Methods of education in Sohak was the consolidation of knowledge and conduct, education of self control, learning of exploration, learning of constructive models, learning of keep the stages and telling stories of the sayings of the saints.

The rural traditional houses in Taebaek mountainous regions play important roles in figuring out values and social aspects of past time including housing life. But due to the introduction of convenient facilities in the current housing life style after industrialized society, many transformations have been taken place even to exist rural traditional folk houses such as installation of new equipment and furniture, the arrangement and function change of rooms, expansion of residential area and etc. So this study aims to secure basic data to prepare installation standard of the convenient facilities as examining convenience facility installation status of the cultural asset designated as rural traditional house, and to identify the meaning and usage of major room of rural traditional houses in order to prepare the proper balances between its original form preservation and residents' convenience living.

Fatigue is a principal failure mode for steel structures, and it is still less understood than any other modes of failure. Fatigue life estimation of metal bridges is a major issue for making cost effective decisions on the rehabilitation or replacement of existing infrastructure. The fatigue design procedures given by the standard codes are either empirical or based on nominal stress approach. Since the fatigue life estimation through field measurements is difficult and costly, more researches are needed to develop promising techniques in the fatigue analysis of bridges through Finite Element Analysis (FEA). This paper aims to develop a methodology for the Fatigue life estimation of railway steel bridge using FEA. The guidelines of IIW-1823-07 were used in the development of the methodology. The Finite Element (FE) package ANSYS and the programming software MATLAB were used to implement this methodology on an Indian Railway Standard (IRS) welded plate girder bridge. The results obtained were compared with results from published literature and found satisfactory.
