Purpose: The study purposes were to construct and test structural equation modeling on the causal relationship of community residents' perceived quality of care, image, and role performance with satisfaction, intention to (re)visit and intention to recommend hospital. Methods: A cross-sectional survey was conducted with 3,900 community residents from 39 district public hospitals. The questionnaire was designed to collected information on personal characteristics and community awareness of public hospitals. Community awareness consisted of 6 factors and 18 items. The data were collected utilizing call-interview by a survey company. Research data were collected via questionnaires and analyzed using SPSS version 20.0 and AMOS version 20.0. Results: Model fit indices for the hypothetical model were suitable for the recommended level: ${\chi}^2=796.40$ (df=79, p<.001), GFI=.93, AGFI=.90, RMSR=.08, NFI=.94. Quality of care, image, and role performance explained 68.1% of variance in community awareness. Total effect of quality of care process factors on satisfaction (path coefficients=3.67), intention to (re)visit (path coefficients=2.67) and intention to recommend hospital (coefficients=2.45) were higher than other factors. Conclusion: Findings show that public hospitals have to make an effort to improve community image through the provision of quality care, and excellent role performance. Support for these activities is available from both Central and Local Governments.

The purpose of this study is to analyze the characteristics of hospital organization structure, organization culture, organization conflict and the interrelation of influential factor in organization conflict. The data for this study were collected through a self-administered survey with a structured delivered to 755 subjects including several nursing staff members, administration staff members and medical technicians at six hospitals. The structural equation model was used to examine the relation of organization structure, organization culture and organization conflict. The results of the analysis in this study were as follows. First, organization structure had a positive influence on organization conflict, especially in terms of complexity and centralization. But, formalization had a negative influence on organization conflict. Second, organization culture had a positive influence on organization conflict, especially in terms of group culture, developmental culture, and hierarchical culture. But, group culture had a negative influence on organization conflict. Third, organization structure had positive influences, especially on organization culture complexity, centralization, and formalization. But, centralization had negative influences too.

Pediatric pancreatitis is not uncommon and results in considerable morbidity and mortality in the affected children. Unlike adults, pediatric pancreatitis is more frequently associated with underlying structural abnormalities, trauma, and drugs rather than an idiopathic etiology. Magnetic resonance cholangiopancreatography (MRCP) is a good imaging modality for evaluating pancreatitis and determining etiology without exposure to radiation. This article focuses on MRCP findings associated with various causes of pancreatitis in children, particularly structural abnormalities of the pancreaticobiliary system, as well as describing the feasibility, limitations, and solutions associated with pediatric MRCP.

This study identified the relationships between the hospital’s organizational pattern for nursing, the organizational characteristics perceived by nurses and their job satisfaction. The study subjects were a convenience sample of 383 staff nurses working at 10 general hospitals with more than 300 beds in Seoul. Hospitals included in the study were classified Into five organizational patterns, where nursing was organized as an independent but lower level, attached to the medical department, attached to a department supporting medicine, and various other organizational pattern. The data were collected from July 10 to August 15, 1992. The organizational characteristics as perceived by the staff nurses were measured by Park & Yoon’s Scale (1986) and job satisfaction was measured by Slavitt’s Scale (1978). The data were analyzed by percentage distribution, Pearson’s correlation, x$^2$-test, t-test, ANOVA, and ANCOVA The summarized results are as follows : 1. The proportion of independent and attached nursing organizational patterns was 35.1％ and 54.9％ respectively. 2. There were differences between four general characteristics of the nurses, age, experience, position and education level, and the five structural types of nursing organization(p〈.05). 3. 1) There were no relationship between the perceived organizational characteristics and general characteristics of the nurses but there was a differ once in job satisfaction according to education level of nurses in hopitals where nursing was an independent department(T=-2.24, p〈.05). 2) There were differences in the perceived organizational characteristics according to age group and experience of nurses (F=3.26, 5.41, p〈 , 05)and in job satisfaction according to the position of nurses in the independent but lower level organizational pattern (T=2.26, p〈.05). 3) There was a difference in the perceived organizational characteristics according to age group (F=3.19, p〈 .05) and in job satisfaction according to the experience of nurses where nursing was attached to the medical department (F=3.49, p〈.05). 4) There was a difference in the perceived organizational characteristics according to nursing unit (F=3.19, p〈 .05), but none between job satis-faction and general characteristics of nurses where nursing was attached to a departiment supporting medicine. 5) There were no relationships between the perceived organizational characteristics and job sat isfaction and general characteristics of nurses in the various other organizational patterns. 4. Nurses in hospitals where nursing is organizationed as an independent department perceived their organizatianal pattern more positively and had higher job satisfaction than nurses working in hospitals where nursing is part of another department. 5. There were differences between perceived organizational characteristics and job satisfaction according to the organizational patterns for nursing (F=13.52, 8.76, p=.0000). 6. There were correlations between the perceived organizational characteristics and job satisfaction of nurses working in two independent nursing departments (r=0.2180, 2351, p〈.05). In conclusion, the relationship between perceived organizational characteristics and job satisfaction was significantly correlated in the hospitals where the nursing department is independent. Perceived organizational characteristics and job satisfaction depended on whether the nursing department is independent from or attached to other departments in the hospital. For nurses job satisfaction the nursing department should be independent from other departments and at the highest level of organization in the hospital.

In this study, the wall stress and rupture risk for abdominal aortic aneurysms were calculated based on the age and geometry of the examined abdominal aortic aneurysms. The geometry of the abdominal aorta was simulated using computed tomography data from patients with abdominal aortic aneurysms. With regard to material properties, the Gasser-Ogden-Holzapfel model was applied to the analysis to simulate the anisotropic hyperelastic characteristics of the artery. In addition, each material parameter was estimated to consider the properties for age and for normal and aneurysm tissue. Moreover, the correlation between the diameter and angle of the aortic aneurysms was analyzed based on data from patients with abdominal aortic aneurysms, and series simulations were conducted. As a result, the rupture risk for the abdominal aortic aneurysms was evaluated based on the age and geometry of the aneurysm.

Natural and expandable graphites were chemically treated in acidic aqueous solutions such as acetic acid or mixtures of acetic acid and nitric acid. Structures and thermal conductivities of the as-treated graphites were characterized in detail. Both graphites were significantly oxidized in the mixed acidic solution of $H_2SO_4$ and $HNO_3$, which condition was generally used for the oxidation of carbon nanotubes. This considerable oxidation of graphites caused a depression of their thermal conductivity. The structural characteristics, obtained by XRD and XPS, show that the graphites treated in the relatively weak acidic conditions (acetic acid or mixture of acetic acid and nitric acid) were quite similar to the untreated graphites. However, the thermal conductivities of both acidic-treated graphites were remarkably increased.

Voice disorder is classified into three categories, structural, neurogenic and functional dysphonia. Neurogenic dysphonia refers to a disruption in the nerves controlling the larynx. Common examples of this include complete or partial vocal cord paralysis, spasmodic dysphonia. Also it occurs as part of an underlying neurologic condition such as Parkinson's disease, myasthenia gravis, Lou Gehrig's disease or disorder of the central nervous system that causes involuntary movement of the vocal folds during voice production. Functional dysphonia is a voice disorder in the absence of structual or neurogenic laryngeal characteristics. A near consensus exist that Muscle tension dysphonia (MTD) is functional voice disorder wherein hyperfunctional laryngeal muscle activity whereas Spasmodic dysphonia (SD) is neurogenic, action-induced focal laryngeal dystonia including several subtype. Both Adductor type spasmodic dysphonia (AdSD) and MTD may be associated with excessive supraglottic contraction and compensation, resulting in a strained voice quality with spastic voice breaks. It makes these two disorders extremely difficult to differentiate based on clinical interpretation alone. Because treatment for AdSD and MTD are quite different, correct diagnosis is important. Clinician should be aware of the specific vocal characteristics of each disease to improve therapeutic outcome.

Background: This study aimed to evaluate the structural changes of temporomandibular joint immediately after condylar fractures with magnetic resonance imaging (MRI). Method: We evaluated 34 subjects of condylar fractures with MRI. The position, shape, and signal intensity of the condyle, disc, and retrodiscal tissue were analyzed with MR images. Results: Immediately after trauma, the disc was displaced with the fractured segment in almost all cases. And, the changes of signal intensity at the retrodiscal tissue were found but less related to the degree of fracture displacement. And, the high signals were observed almost at all fractured joint spaces and even at some contralateral joints. Conclusions: The displaced disc as well as the increased signal intensity of the joint space, condylar head, and retrodiscal tissue demands more attention to prevent the possible sequela of joint.
