Globally, South Korea is a country that has a lot of $CO_2$ emissions and has steadily increased its total greenhouse gas emissions since the 1990s. With the recent implementation of the carbon emission trading system in Korea, the importance of calculating $CO_2$ emissions of construction equipment is increasing, hence the need for accurate calculation of environmental penalties through allocating carbon emission rights. This study presents a methodology to predict the price of carbon credits using big data analysis method. This methodology is based on correlating and regression analysis of trends in carbon emission prices and search volumes. This study aims to support faster and more accurate budget calculations in the planning of the construction process based on the predicted price of carbon emission rights.

Purpose: This study was to explore the experiences of perioperative patients with cancer. The purpose of this inquiry was to describe the essence of such experiences, and to understand them from the patients' point of view. Method: Participants in this study were 9 cancer patients with ages ranging from 31 to 70 years old, living in B city, who experienced cancer operations. Data collection consisted of in-depth interviews and an observation method done from October to December in 2003. In analysing data, Colaizzi's(1978) phenomenological research method was adopted. Results: Five categories emerged from ten theme clusters. The five categories were: 'shock', 'expectations & wishes', 'despair', 'feelings of burden', 'continual pain'. Conclusion: The results of this study showthat oncology nurses need to pay more attention to the psychosocial aspect of nursing to empathize and support the cancer patients who suffer and its treatment, and operations.

The purpose of this study is to get the data on the day-care type of the employed mothers in urban area and to make it improve the day care service program. I classified day care type into four classes accoding to existing one. And we surveyed 401 employed mothers with the child under age of six who lived at Seoul. the major results were as follows; 1) Most of employed mothers felt the burden of day care expenses and payed it of their own earning 2) The common type of day care is 'by family' and the users of this type more satisfied with the condition than any other types. 3) the difficulty of day care is that can't apply the tool and materials sufficiently, except day care center, 4) The reason that they use day care center or not is thier family. 5) Accoding to child age, family composition, educational level, job, income level, employed mothers choose day care type differently. So I suggest the social support for the employed mothers.

To reduce an authors burden in hypermedia system that allows non-sequential information the process of creating links must be easy. However, most of the conventional hypermedia systems possess two difficulties. First, the author must go through several troublesome process to create a single link. Secondly, it is not easy to create an anchor in text or other multimedia data. Therefore, in order to support effective construction of hypermedia system the editing environment must provide an easy method to create links. In this paper, to resolve the weaknesses of conventional hypermedia system as mentioned above, an editing tool is developed and implemented to easily create the links of multimedia data. There are three methods in creating links and a user can select a convenient method in given circumstances. And for teh efficient production of nodes composed of multimedia information, we provide an authoring environment to integrate and process those informations.

Purpose: This study was done to develop a model which explains factors influencing caring behavior of mothers who have children with disabilities, and to verify the appropriateness of the model and the relationship among variables. Methods: The participants in the research were the mothers who had a 3 to 12 yr-old children with disabilities. The data were collected from 451 mothers through self-reported questionnaires from July 14 to 31, 2008. A total of the 371 data sets were analyzed using SPSS/WIN 11.5 and AMOS 5.0 version. Results: The children's behavior characteristics, social support, objective burden and parenting self-esteem had an impact on the mothers' caring behavior. Especially, parenting self-esteem including parenting satisfaction and self-efficacy was the most influential factor. These variables explained 77% of the mothers' caring behavior for these children. Conclusion: The results suggest that some strategies for promoting mothers' parenting self-esteem focused on parenting satisfaction and self-efficacy should be developed in order to help mothers in caring for their child who is disabled.

Pulsatile Extracorporeal Membrane Oxygenation(ECMO) can mitigate the heart load and raise the patient's blood perfusion. But If the ECMO pulsate the blood flow during the systolic period, It can burden to the patient's heart. To avoid the heart injury, we have to consider the relation between output of ECMO, hemodynamic states and heart movement. To raise the efficacy of the pulsatile ECMO, we investigated the coronary perfusion, cardiac muscle tension and hemodynamic states during the ECMO perfusion by using the mathematical model of human blood circulatory system and ECMO. The outflow data of the pulsatile ECMO(T-PLS, Bioheartkorea, Korea) was obtained in vitro experiments. According to the phase and pumping rate of the ECMO, the heart's load and coronary perfusion could be adjusted to the proper levels. The results of the human- ECMO lumped parameter model showed that the synchronizing operation of the pulsatile ECLS can be helpful at stabilizing the patient's hemodynamic states.

The purpose of this study was to identify caregiving situations and to examine resources for adjustment among family caregivers of the elderly with dementia. Thereby the study can provide the basic information for the development of education programs for family caregivers through in-depth interview. The main result of this study was as follows : 1) The major problems identified by family caregivers I caring for the elderly with dementia were related to care recipient's toileting and to care recipient's confusion and wandering. 2) The family caregiver expressed feelings of burden including chronic fatigue, depression, guilt and frustration. 3) The factors influencing the adjustment of family caregivers for demented elderly were quality of relationship, motivation for caregiving, circumstances of caregiving, social support and coping strategies.

Active power filters can be cost-effective for use in practical systems with the insertion of a few passive elements in shunt or series configuration. The resulting hybrid filters can be designed to provide dominant lower order harmonic elimination and reactive power support by the passive elements so that the burden on the active filter counterpart is reduced. In this paper, the rate reduction in the shunt active filter is estimated when it is connected in parallel with suitable passive tuned harmonic filters. The active filtering system is based on an appropriate control scheme. The simulation and the experimental results of the shunt active filter, along with the estimated value of reduction in rating, show that the hybrid shunt filtering system is quite effective in compensating for the harmonics and reactive power, in addition to being cost-effective.
