Purpose: The purpose of this qualitative study was to explore the meaning of the experience of Korean immigrant nurses working in US hospitals. Methods: Purposive sampling yielded 15 Korean immigrant nurses who had more than one year of clinical experience in US hospitals. Data were collected from March to August 2012 through in-depth interviews and thematic analysis was conducted using van Manen's hermeneutic phenomenological approach. Results: The findings were classified into eight themes: 'struggling from staff at workplace being territorial to outsiders', 'feeling oppressed due to language barrier', 'accepting rational and horizontal relationships at work', 'staying alert in the environment where lawsuits are rife', 'feeling a sense of stability from the social system that values human dignity', 'maintaining self-confidence from prominent nursing practices and senior Korean nurses' professional reputation', 'performing essential comprehensive nursing care', 'promoting self-development to be equipped with professionalism.' Conclusion: The findings indicate that the Korean immigrant nurses were able to excel in their workplace when their clinical experience at US hospitals was combined with the lived space in US politics and environment, lived time of patience, lived body to be alert, and lived others with multi cultural characteristics.

Purpose: The purpose of this study is to compare the user satisfaction between 4-bedrooms and 5/6-bedrooms in a single general hospital. Methodology: To measure and compare multiple-bed ward user satisfaction between 4-bedrooms and 5/6-bedrooms, questionnaires were collected from 916 inpatients and 129 nurses in a single general hospital. The patient satisfaction questionnaire categories included environmental conditions, protection of privacy, and medical services. The nurse satisfaction questionnaire categories included space, infection control, patient safety, work load and psychologic view point. Findings: Satisfaction of patient who admitted in 4-bedroom to the environmental conditions and protection of privacy was higher than that of 5/6-bedroom group (3.91 vs. 3.25, p<0.001). Satisfaction of nurse who worked in 4-bedroom was higher than that of 5/6-bedroom (3.05 vs. 1.92, p<0.001). By the multiple linear regression analysis, patient satisfaction to the environmental conditions and protection of privacy was related with multi-bedroom type and location of beds; 4-bedrooms were higher than 5/6-bedrooms(p<0.001), window side bed were higher than hallway side bed(p=0.001). There was no satisfaction difference in comparing medical services between the two groups. By the multiple linear mixed regression analysis, nurse satisfaction who were assigned for 4-bedrooms were higher than that of 5/6-bedrooms in all categories(p<0.001). Practical Implications: Even though no difference has shown in medical services satisfaction between the two patient groups, multi-bedroom type may affect patient satisfaction in environmental condition, protection of privacy and may also affect overall nurse satisfaction. This result suggests that to improve multi-bedroom user satisfaction, 4-bedroom is recommended over 5/6-bedroom.

A Space Launch Vehicle (SLV) for Launching Satellites Consists of Multi-stage Rockets for the Purpose of Efficient Flight and Accomplishes the Launch Mission through Flight Events such as Stage Separation, Engine Start and Stop. In this Process, the SLV is Supposed to Undergo the Processes of the Powered Flight Section in which the Engine Generates Thrust and the Ballistic Flight Section in which there is no Thrust Repeatedly. Because it is Difficult to Express these Flight Characteristics of the SLV as a Single Dynamics Model, much Research on Tracking Algorithms using Multiple Models has been Undertaken. In case of using the Multiple Model Tracking Algorithm, it is Expected to Improve the Tracking Performance of the SLV. However, it is Difficult to Select Proper Dynamics Models to be used and the Calculation Amount Increases due to the use of Multiple Models. In this Paper, we Propose a Method to Track the SLV with Diverse Flight Characteristics Efficiently by only Two Kalman Filters using Constant Acceleration Model and Adaptive Singer Model.

The judging criteria for the landscape design set by the Dalseong-gun could be articulated as follows : an environmentally friendly design which respects the surrounding n a locale which functions as a community center of Dalseong-gun, a resting place for the welfare of its employees and visitors, and finally a place with diverse landscape elements reflecting the individual identity of each facility. The main design concepts of this project could be summarized as follows : an environmentally friendly design which respects and utilizes the existing natural landscape resources, a design which features a harmony of nature with architecture and exterior space with interior space, and a design which balances esthetic form and practical function. This design consists of four major outdoor spaces ; the lawn, the entry plaza, a pine grove, and a deck area on the third floor. The multi-purpose lawn area near the main entrance area can be used for flea markets, outdoor weddings, and picnics for its neighbors. The adjacent plaza and parking lots can be unified as one space in case of large events. The entry plaza has three axes. Each of them represents the Assembly, the Administration, and the Culture. A big circle in the paving pattern unifies the three individual axes. A group of Zelkova trees was introduced to reflect local flavor. The existing pine grove was preserved as a symbolic 'park' for the Gumpo district. The outdoor amphitheatre within the grove was introduced by utilizing the existing topography, The flow of 'nature'on the deck area was designed to connect Mt. Gumkae with the 'city'. It is a comfortable resting place for its employees and visitors.

This paper presents a new infinite element for modeling far-field region in dynamic analysis of a fluid-saturated two-phase medium. The infinite element method combined to the infinite element method has been effectively applied to several engineering problems where the full space or half-space medium should be modeled. However, the currently available infinite element for dynamic analysis of two-phase porous medium has a limitation that Pl and P2 waves can only be Included in shape function expressing behavior ol the body. In this paper, the infinite element method is extended to simulate arbitrary number of multi-component waves. For this purpose, the far-field of the porous medium is assumed to be a layered half-space, while the near-field Includes structures as well as irregular soil medium. The accuracy and effectiveness of the proposed element have demonstrated using 1-D and 2-D wave propagation problems.
