This study tries to develop the typology of relative costs-benefits perception about the transition to parenthood and explore the group differences in the socio-demographic variables, family context variables, and social support level. For these purpose data was gathered from 342 fathers who experienced the transition to parenthood within past three years. The major findings were as follow. 1. The level of men's perceived benefits about the transition to parenthood was higher than the level of costs. 2. The typology of relative costs-benefits perception about the transition to parenthood were , , and . The discriminant variables among 4 groups were marital satisfaction. birth planning educational attainment, and kinship's emotional support.

The purpose of this study was to figure out the urban establishing families' marriage costs and first housing costs. For the purpose 274 establishing families in Seoul and its metropolitan area were interviewed through the stadardized questionnares. Finally 264 questionnares were analyzed. The major findings were as follows ; 1) The total marriage costs of urban establishing families were very high and the contents were very ritualistic. In higher education group, the total costs were high relatively. This was the case in first housing costs. 2) Their marriage costs were very dependent on their parent, the dependency were stronger in high education group compared to the low. This ware the case in first housing costs. 3) The total marriage costs were higher than the first housing costs. This tendency was stronger in low education group compared to the high.

This paper presents the classification scheme of the signal facilities on the railroad considering the construction costs and maintenance costs in a low population area. The construction costs of the new signal facility system can be compare with the costs of the present signal facilities as the classification scheme. The signal facilities on the railroad were classified as the railroad security regulations and then the scheme is considered through the LCC analysis. In order to test this research, the costs of signal facilities obtained from ones on TAEBACK railroad line. The costs categorized the construction costs, the labor cost and the maintenance costs can be effectively applied to the LCC analysis. The scheme is very useful to make a decision whether the new signal facilities on railroad in low population area is build or not in terms of the costs.

This paper deals with the topical problems of the Life Cycle Costs in connection with the rolling stocks. the LCC philosophy has already entered the third decade. this philosophy contributed towards the new relationship's comprehension between railway vehicle producers' and railway vehicle users' sphere. this leads together to the technical-economical solution convenient for the both sides. In the point of manufacturer, It is said that low operational costs could be reached using a well-designed and structured maintenance program. this is due to the proper technical analysis of critical components that leads to low costs of maintenance and a superior reliability without increasing the capital investment. but, This paper presents both topical experiences with the LCC models for the railways vehicles and also procedures during Life Cycle Costs calculations. In conclusion I want to introduce how to calculate LCC & what kinds of softwares are used based on VVVF EMU vehicle

Background: Related to escalating health care costs and the questionable effectiveness of multiple interventions including lumbar facet joint interventions, cost effectiveness or cost utility analysis has become the cornerstone of evidence-based medicine influencing coverage decisions. Methods: Cost utility of therapeutic lumbar facet joint nerve blocks in managing chronic low back pain was performed utilizing data from a randomized, double-blind, controlled trial with a 2-year follow-up, with direct payment data from 2016. Based on the data from surgical interventions, utilizing the lowest proportion of direct procedural costs of 60%, total cost utility per quality adjusted life year (QALY) was determined by multiplying the derived direct cost at 1.67. Results: Patients in this trial on average received $5.6{\pm}2.6$ procedures over a period of 2 years, with average relief over a period of 2 years of $82.8{\pm}29.6$ weeks with $19{\pm}18.77$ weeks of improvement per procedure. Procedural cost for one-year improvement in quality of life showed USD $2,654.08. Estimated total costs, including indirect costs and drugs with multiplication of direct costs at 1.67, showed a cost of USD $4,432 per QALY. Conclusions: The analysis of therapeutic lumbar facet joint nerve blocks in the treatment of chronic low back pain shows clinical effectiveness and cost utility at USD $2,654.08 for the direct costs of the procedures, and USD $4,432 for the estimated overall cost per one year of QALY, in chronic persistent low back pain non-responsive to conservative management.

Logistic costs refer to trade costs, but it could influence FDI as well as global trade. Multinational corporations choose the geographic organization to produce their products. Therefore, it involves many countries to produce one product. International trade between countries more frequently involves the trade of raw materials, components, and unfinished goods. This implies that countries with better logistic performance are attractive for investment because of low transaction costs. Using the logistic performance index provided from the World Bank, this paper investigates the impacts of logistic performance on FDI inflow to developing countries. Results show that infrastructure and timeliness have a positive effects on FDI inflow to low income countries. In the case of middle income countries, timeliness has a negative effect on FDI inflow. This discrepancy between the low- and middle- income countries comes from the different motivation. FDI for low income countries primarily attempts to minimize labor costs. However, FDI for middle-income countries seems to be motivated to reduce labor costs and expand sales markets. FDI inflow in low-income countries serves as part of the offshoring or global outsourcing of multinational corporation.

The purpose of this study was to investigate the effects of parenting on job satisfaction and psychological well-being in employed women, with moderating effects of marital stress. The present study was based on a sample of 258 full-time employed women aged 30-49 in dual-earner families. The effects of parenting experiences on job satisfaction and psychological well-being were examined separately for women with low and high marital stress. Both parenting rewards and costs were significantly associated with psychological well-being in women with high marital stress. For women with low marital stress, parenting rewards and costs did not predict psychological well-being. Among women with high marital stress, parenting rewards were positively associated with psychological well-being and parenting costs were negatively associated with psychological well-being. In contrast, only parenting costs were a good predictor of job satisfaction for women with high marital stress. In conclusion, the effects of parenting experiences on job satisfaction and psychological well-being were mediated by the level of marital stress in employed women.

This study explored the characteristics, housing deficits and expectations for support programs of low-income renter households in housing poverty in order to provide housing policy development and improvement information. Microdata of the 2014 Korea Housing Survey was utilized as secondary data for this study. A total of 2,508,672 low-income renter households (weighted count) in the bottom 40% income ranks of entire general households living in private rental units were selected as study subjects. The major findings were as follows. (1) One point four percent of the subjects were living in non-house living quarters (e.g., shanties, vinyl greenhouses, container houses, and mud huts), 1.4% were in dosshouses, 9.9% were in basements, semi-basements or rooftop units, and 8.2% were in sub-standard units. (2) Among the households whose housing costs burdens were measurable, 75.7% were found to have housing cost burdens to pay 30% or more of their household income towards housing costs (rental costs and maintenance costs), but only 7.5% of the burdened households received a housing voucher. (3) Eighty-one percent were found to be in a housing poverty status as defined by the researcher; in addition, low-income renter households in housing poverty in Seoul tended to have a greater proportion of households headed by females, the elderly, and be persons with low-education or disabilities. (4) Households in housing poverty showed greater expectations for financial support and/or extended provisions of public rental housing than other low-income renter households.

Since 1995 the Korean Ministry of Science and Technology has introduced and implemented a project based system (PBS) for awarding R&D funds. While capital investments for national laboratories such as buildings and research facilities are supported by the government, normal operating expenses including personnel expenses should be earned by national laboratories through open competition under PBS. The project budget includes both direct research costs and indirect costs. The purpose of this paper is to examine the components of indirect costs and to examine determinants of indirect costs of national laboratories in Korea. The indirect costs of nineteen national laboratories are examined. The direct personnel costs and indirect personnel costs out of total personnel costs are 72% and 28%, respectively. The average indirect cost rate is 74.1% of direct personnel costs. Major components of indirect costs are general operating costs, indirect personnel costs, taxes and dues, and expenses related to the usage of equipment. The significant determinants of indirect cost are indirect personnel ratio. the ratio of unique projects, the type of national laboratories (pure research laboratories or other), and asset activity ratio measured as research divided by total assets. The high indirect personnel ratio, the high ratio of unique projects, the laboratories classified as other, the low asset activity ratio are related to high indirect cost rates.

This study examined housing costs and housing affordability of young college graduate renters in the Capital Region of Korea using microdata of the 2012 Korea Housing Survey (KHS). A licensed microdata set of 2012 KHS was obtained on September 29, 2012 from the official KHS Website and analyzed statistically. I selected 93,795 young college graduate renters between 20 and 29 years of age in the Capital Region and compared their housing costs across income levels and tenure type. Major findings were as follows: (1) Jeon-se deposit was on average 3.1 times the annual household income and monthly renters' deposit was 7.1 times the monthly household income; (2) households in higher income groups tended to pay a larger deposit and/or monthly rent; however, households with a lower income were found to pay a greater proportion of income to housing costs than households with a relatively higher income; (3) a total of 64% of all young college graduate renters had housing cost burdens to pay 30% or more of their income for housing, and more than 78% of the low-income households were found burdened; and (4) after housing cost payments, low-income households had less than one million KRW left to spend on other needs and savings; in addition, some low-to mid-income households had zero or even minus income left after housing cost payments.
