Purpose: This study was conducted to investigate the factors influencing the quality of life among the patients with Crohn's disease. Method: Data were collected from 97 Crohn's disease patients between September 17 and October 20 in 2009. The collected data were analyzed by SPSS program. Results: There were significant differences in the participants' quality of life depending on their age, economic status, pain, diarrhea, weight loss, Crohn's disease activity index (CDAI), and use of medications such as antidiarrhotica, steroid, and analgesics. The results also showed the correlations between the participants' qualities of life and thier pain, CDAI, anxiety, depression, perceived health condition, and of body image. Finally, the factors affecting the quality of life in patients with Crohn's disease included anxiety, perceived health state, pain, and CDAI. The explanatory power of these factors was 79.5%. Conclusion: The results imply that controlling the patients' pain and providing emotional support for anxiety reduction are crucial. In a similar vein, tailored nursing interventions considering individual patients' conditions are believed to help the patients positively perceive their disease. A future research, can conduct further investigations of these factors from more diverse perspectives, which is expected to promote more effective nursing strategies for Crohn's disease patients.

Currently, the Korean construction industry is shifting its interest to the overseas construction market because of a stagnating domestic market. In the meantime, the international housing construction market is expanding with respect to new city development projects that are supported by population growth and urban migration. Despite the Korean construction industry's expertise in new city development, technology, and systems for apartment supply, the share of Korean players in the international housing construction market is continuously decreasing. As a measure to overcome this situation, the authors of this study considered the paper "The Development of a Cost Effective, Long-life Housing Model and Construction of Testbed," which is currently in progress as a part of national project. Through literature review and interviews with experts, the authors determined that there are "column+minimum interior (infill)" apartments that are similar to the long-life housing in some areas of China, Southeast Asia, and Russia. Candidate countries expected to be feasible for the entry of long-life housing were selected by determining the top countries that have already entered the long-life housing market and analyzing those selections through additional specific techniques. The external environments of the selected countries were also analyzed. Please refer to the full paper for details.

In this study, based on Weibull proportional age reduction model and age replacement policy, we analyze economic life of cutting tool which allows re-grinding. Re-grinding task, usually for high-priced machining tools(e.g., broaching tool), is a kind of preventive maintenance activities to extend tool life at the completion of a lot production. The numerical results are also presented. Among the parameters of Weibull proportional age reduction model, the re-grinding effect parameter and Weibull shape parameter have a strong effect on economic tool life, and in the cost parameters, shortage cost is most sensitive. With further study on the parameter estimation of tool life process and cost function, this study can be expected to give more practical contribution to management of general machining tools.

End-of-life patients experience physical, mental, social, and existential distress. While medical personnel provide medication and care to alleviate patients' distress, listening to and interacting with patients remains essential for understanding their psychological condition. The most important tool, though difficult to implement in practice, is end-of-life discussion (EOLD). EOLD has been shown to have positive effects on end-of-life treatment choices, achievement of patients' life goals, improvements in the quality of life of patients and their families, and the prevention of depression and complicated grief among bereaved family members. EOLD is not often undertaken in clinical practice, however, due to hesitancy among medical personnel and patients for various reasons. In order to conduct an EOLD, the patient's judgment, psychiatric illnesses such as delirium and depression, and psychological issues such as the side effects of psychotropic drugs, denial, and collusion must be evaluated. Open and honest conversation, treatment goal setting, the doctor's familiarity with the patient's background, and attentiveness when providing information are important elements for any dialogue. Meaning-centered psychotherapy was developed to alleviate the existential distress of cancer patients, and its application may promote EOLD. The future development of meaning-centered psychotherapy in practice and in research is expected to further promote EOLD.

The function and purpose of the marine rubber fender, to prevent the damage of the ship and the mooring while the ship is being attached to the pier. However, maintenance of the fender after installation is not enough, because it is generally handled as an attachment facility. Estimation the life of a marine rubber fender is important in the maintenance of a port. When manufacturers design and produce marine rubber fenders, they do so according to various conditions such as the reaction force acting on the hull and docking vessel and deformation after absorbing the kinetic energy of the ship. In this study, a method for predicting and evaluating service life from the product design and development stage was established, in order to evaluate the durability of the marine rubber fenders. The SSp-300H and HSP-300H models were used to predict the service life. The method developed in this study, is expected to predict the service life of the marine rubber fender accurately and in a comparatively shorter time, thereby contributing to the evaluation standard and quality stability of the product.

Concerns over the environment have spawned a number of research studies in the construction industry, as the construction of built environments and large infrastructures involves diverse environmental impacts and loads of hazardous emissions. Many researchers have attempted to quantify these environmental loads, including greenhouse gases, carbon dioxide, nitrogen dioxide, and sulfur dioxide, to name a few. However, little research has been conducted regarding integrating the life-cycle assessment (LCA) of environmental loads with the current life-cycle cost analysis (LCCA) approach. This study aims to estimate the environmental loads as a monetary value using the European Climate Exchange (ECX) rate and, then, to integrate those impacts with the pure construction cost. Toward this end, this study suggests an integrated approach that takes into account the environmental effect on the evaluation of the life-cycle cost (LCC). The bill of quantity (BOQ) data of a real highway project are collected and analyzed for this purpose. As a result, considering the environmental loads in the pavement process, the total LCC increased 16% from the traditional LCC cost. This study suggests an integrated approach that will account the environmental effect on the LCC. Additionally, this study is expected to contribute to better decision-making, from the perspective of more sustainable development, for government as well as for contractors.
