The objective of this study is to examine the effectiveness of the strategy of hospital specialization by analyzing the differences in expected and perceived services, perceived service quality, satisfaction, and intentions to revisit and recommend the hospital to others between general and specialty hospitals. Data were collected using self-administered questionnaire from patients admitted to four study hospitals: two speciality and two general hospitals. The questionnaire was developed based on SERVQUAL to measure five dimensions of service quality. Four hundreds questionnaires were distributed to inpatients or their guardians and 282 returned questionnaires were used in the analyses. The significance of the differences in study variables between specialty and general hospitals were tested by t-test and $x^2$-test. The factor analysis result confirmed the construct validity of 28 questions asked to measure service quality and resulted in four dimensions of service quality: reliability, assurance, tangible and empathy/responsiveness. Cronbach's Alpha ranged from .9013 to .9358, that confirmed the internal consistency of answers. The study results indicated that patients who used specialty hospitals had higher levels of expected and perceived service, a higher level of perceived service quality, and higher levels of service satisfaction than patients who used general hospitals. Percents of patients who had the intention to revisit the hospital and to recommend the hospital to others were higher among patients in specialty hospitals. The most frequent reason to choose the hospital was the excellence of doctors in both general(29.9%) and specialty(43.8%) hospitals, that was followed by convenient transportation(15.3%) and someone know works at the hospital(15.3%) in general hospitals and other's recommendation(14.6%), and nice amenities(13.1%) in specialty hospitals. Although there were no significant differences in clinical department, age, and sex of patients between general and specialty hospitals, patients who visited speciality hospitals had higher levels of education and income than their counter part in general hospitals. These results suggested that specialty hospitals performed better than general hospitals. Specialization could be a viable strategy to tide over recent financial difficulties experienced by hospitals, particularly small- and medium-sized hospitals.

Structural analysis for a large-scale fault in Maegok-dong, Ulsan, was carried out based on filed-works to investigate the geometric and kinematic characteristics of the fault as well as its Quaternary slip. As results, a series of repeated stratigraphy, minor faults, fracture zones, and deformation band clusters are observed over a distance of about 100 m in the first studied site consisting of sedimentary rocks, which may indicate the damage zone of a large-scale fault in this site. In the second site, mainly composed of granitic clastic rocks, a large-scale thrust fault is expected based on low-angle dipping faults showing branched and/or merged patterns. Age of the last slip on this fault was restrained as after 33,275 ± 355 yr BP based on radiocarbon dating for organic material included in the gouge zone. Dimension of fault damage zone, dominant sense of slip, and age of the slip event associated with the fault suggest that these structures have a close relationship with the Ulsan Fault and/or Yeonil Tectonic Line, which are well-known large-scale neotectonic structural features around the study area. Therefore, it is necessary to study the characteristics of the faults in detail based on structural geology and paleoseismology in order to ensure seismic and geologic stability of the buildings under construction, and to prevent geologic hazards in this area.

The study aims to explore a new direction for research on buttons by understanding the functions and artistic features of buttons on Western clothing in the 18th and 19th centuries, and to use the findings to develop a textile design. In terms of the research method, the period was set in the 18th and 19th centuries, when decorative features and artistic values of buttons on Western clothing reached theirpeak, while theoretical analysis was made based on literature and previous research papers on Western clothing, websites of the Metropolitan Museum and French Museum of Decorative Arts and other website materials, as well as special exhibition materials of the National Museum of Modern and Contemporary Art. Textile designs were developed using computer programs, including Clip Studio Paint and Adobe Photoshop, by integrating the reinterpreted motif of buttons in the 18th and 19th centuries and the styles that prevailed at that time. The results are as follows. First, buttons on Western clothing had the following three functions: a practical function, a symbolic function representing the wearer's status, and a decorative function expressing individuality and beauty. Second, buttons in the 18th century were works of art made with various handicraft techniques and were an important medium that expressed the wearer's fashion sense. In addition, buttons in the 19th century were mass-produced as a result of industrialization and took a major step forward with the development of materials and dyeing. Buttons reflected themes of poetry, drama, biblical stories, music and art, lifestyle,, along with the political and social atmosphere that rapidly changed after the revolution and fashion trends. Third, the artistic features and shapes of buttons were reinterpreted to create a design motif, and the design was developed reflecting the characteristic elements of the rococo style of the 18th century and the art nouveau style of the 19th century that can conform to modern fashion, thereby rediscovering the artistic meaning and value implied in buttons. In the future, the research on creative buttons of 20th century artists is expected to be conducted from various perspectives.

The purpose of this study is to understand the idea of the ideal garden, pursued by Dasan, by analyzing the production process of his writing and the location of his dwelling, and the characteristics of the garden in the writings of Dasan (茶山) Jeong Yag-Yong (丁若鏞)'s "Jaehwangsangyuincheop (題黃裳幽人帖)" is concerned with his writings on an imaginary garden (意園). This paper assumed that "Jaehwangsangyuincheop" served as a blueprint for his ideal dwelling. The main research subjects are the external scenes described in the "Jaehwangsangyuincheop", and the garden elements and spatial construction that were visualized as a Korean Ink Painting (水墨畵) through the analysis of related works. The results are as follows. First, Hwang Sang was Dasan's favorite pupil, and "Jaehwangsangyuincheop" was written by Dasan while at Boeunsanbang in the winter of 1805 as an answer to a question that Hwang Sang posed about the residence of a hermit. By referring to this response, Hwang Sang established Ilsoksanbang (一粟山房) under Mt. Cheongae in Daegu-myeon, Gangjin. Secondly, the residence in "Jaehwangsangyuincheop" has mountains behind it and water in front of it (背山臨水). The residence was used as a place to combine life and leisure. It was an ideal residence that secluded the scholar(隱士). Thirdly, Dasan's ideal garden was shown as operation of natural geography in a residential location, practically using various plant materials, expanding physical boundaries of garden, pursuing synesthetic aesthetics while enjoying garden elements, and having an active experience of the taste for the arts in the extended garden. "Jaehwangsangyuincheop" depicted the life of a scholar with the taste of elegance (雅趣), who live in reclusiveness (隱逸), which was wanted by Dasan after exile. It was realized as Ilsoksanbang. "Jaehwangsangyuincheop" was interpreted as the ideal of a feasible dwelling that faithfully reflects Dasan's conceptual thoughts on the garden.

Stents are frequently used throughout the human body. They keep pathways open in vascular or nonvascular duct for a long time. Therefore its stability is very important factor. In recent years, aconsiderable amount of research has been carried out in order to estimate mechanical properties of the stent such as expansion pressure behavior, radial recoil and longitudinal recoil using FEM (Finite element analyses). However, published works on simulation of stent fatigue behavior using FEM are relatively rare. In this paper, a nonlinear finite-element methodwas employed to analyses the compression of a stent using external pressure and fatigue behavior. Finite element analyses for the stent system were performed using NASTRAN FX. In conclusion this paper shows how the stent is behaved in the body, and its fatigue behavior.

There are several approaches for reducing the ROB(Reorder Buffer) complexity in processors. The one technique that makes the simplest ROB ports relies on a distributed implementation that spreads the centralized ROB structure across the functional units(FUs). Each distributed buffers are decided on the size of them by workload of the functional units. The performance of the processor depends on the size of distributed ROB. However, most of previous works have depended on the simulation results to decide the optimsize of distributed ROB. In this Paper, we use an analytical model based on the M/M/1 Queuing theory to determine the optimum size of each distributed ROB. Our schemes are evaluated by using the simulation performed by the CPU2000 benchmarks. We are able to choose the optimum size of distributed ROB showing the 99.2% performance compared with existing superscalar processors. We can save 82% hardware resources in ports and reduce more than 30% of delay when ROB and distributed ROB proposed in this paper are designed by HDL.

In the Western Philosophy that was centered on reason, sense has been belittled as a low level of conception under reason. However, the 21st century modern visual environment pushes away the epistemology centered on reason and puts 'sensuality' and 'sense' on its place. Especially, public films are one of the fields that rapidly reflect such changes and lead the changes. However, unfortunately, it is difficult to find such efforts that reflect the artistic and aesthetic significance of sense from the public films. It is because that sense is considered superficial and somewhat not real, while recognizing sense as the low level of conception under reason over the long history. Given the fact, this study reviews the by Gilles Deleuze, a modern philosopher who gives a new value on sense, and it would be meaningful to analyze the works of Chris Cunningham who makes films with the concept of Gilles Deleuze. After we analyzed three music videos of Aphex Twin directed by Chris Cunningham, we can ascertain that the films are based on body without Oranges, hysteric, and diagram that are suggested from by Gilles Deleuze. Analyzing recently released films centered on 'sense' in a superficial manner that includes production method or picture composition, including the films of Chris Cunningham, falls into the error of overlooking the director's aesthetics. Understanding the modern logic of sense that is newly developing, studying its substance, and analyzing the films will make a sacrifice of suggesting a new alternative.

Cadastre is a set of activity registering diverse land information in national scope land management works. A nation examine land information and register it in a cadastral book, and must update data when necessary to properly maintain the information. Currently, local governments execute work about parcels of land alternation by manual work based on KLIS road map. Therefore, it takes too much time-consuming and makes problem as missing lots of parcels of land alternation. This study suggests the method selecting the parcels of land alteration for Jinan-Gun of Jeollabuk-Do using the GIS spatial overlay and the following results are as belows. Firstly, the manual work on the parcels of land alteration was greatly improved through automatically extracting the number and area of parcels according to the land classification and ownership by GIS spatial overlay based on serial cadastral maps and KLIS road lines. Secondly, existing work based on KLIS road lines could be advanced by analyzing the parcels of land alternation using the actual-width of the road from new address system to consider all road area for study site. Lastly, this study can supply efficient information in determining the parcels of land alternation consistant with road condition of local governments by analyzing the number and area of parcels according to the land classification and ownership within various roadsides ranging from 3m, 5m, and 10m by GIS buffering method.

The folk language that lives and breathes in modern works does not just come from old stories, but it is a personal narrative which is based on the experiences of the narrator. Like many genres in oral literature, most of these personal narratives occur from the impulse of communicating and reinventing rather than from the impulse of creating. Compared to traditional folktales, stories about an individual's experiences, such as personal narratives are often performed by adding the individual tendencies of the narrator. In so doing, the phenomenon of "processing the experience by estimating it and reinterpreting the memories roughly" occurs, and this is a significant factor in making the oral literature. However, the question that arises here is: How can we deal with these significant elements that are inevitably captured when performed orally? Text linguistics, the main methodology of this paper, implies the possibility of expressing the impromptu elements of oral literature. Also, textual linguistic analysis of personal narratives provides the possibility of discussing oral characteristics from various angles which have been difficult to analyze, such as on-site atmosphere, speaker mistakes, contradictions in stories, and audience reactions. Hence, it is possible to effectively discuss oral-poetics in oral literature which are based on the one-off of 'words', the 'roughness' of the on-site atmosphere, and the stackability of the 'wisdom of crowds'. Furthermore, it is expected to contribute to the study of personal narrative storytelling that plays an important part in Veabal art in community culture.

Magnetoelectric (ME) composites are comprised of magnetostrictive and piezoelectric phases. Lots of theoretical and experimental works have been done on ME composites in the last couple of decades. The output performance of ME composites has been enhanced by optimizing the constituent phases, interface layer, dimensions of the ME composites, different operating modes, etc. However, the detailed information about the characterization of ME coupling in ME composites is not provided yet. Therefore, in this tutorial paper, we are giving an insight into the details of measurements of ME voltage coefficient of ME composites both at off-resonance and resonance conditions. A symmetric type Gelfenol/PMN-PZT/Gelfenol ME composites were fabricated by sandwiching (011) 32-mode PMN-PZT single crystal between two Galfenol plates by epoxy bonding are used for the example of ME coupling measurement. The details about the experimental setup used for the measurement of ME voltage coefficient are provided. Furthermore, a step-by-step measurement of ME voltage coefficient using computerized program is demonstrated. We believe the present experimental measurement details can help readers to understand the concept of ME coupling and its analysis.
