Background: The ultimate goal of craniofacial reconstructive surgery is to achieve the most complete restoration of facial functions. A bioabsorbable fixation system which does not need secondary operation for implant removal has been developed in the last decade. The purpose of this study is to share the experience of authors and to demonstrate the efficacy of bioabsorbable mesh in a variety of craniofacial trauma operations. Methods: Between October 2008 and February 2015, bioabsorbable meshes were used to reconstruct various types of craniofacial bone fractures in 611 patients. Any displaced bone fragments were detached from the fracture site and fixed to the mesh. The resulting bone-mesh complex was designed and molded into an appropriate shape by the immersion in warm saline. The mesh was molded once again under simultaneous warm saline irrigation and suction. Results: In all patients, contour deformities were restored completely, and bone segments were fixed properly. The authors found that the bioabsorbable mesh provided rigid fixation without any evidence of integrity loss on postoperative computed tomography scans. Conclusion: Because bioabsorbable meshes are more flexible than bioabsorbable plates, they can be molded and could easily reconstruct the facial bone in three dimensions. Additionally, it is easy to attach bone fragments to the mesh. Bioabsorbable mesh and screws is effective and can be easily applied for fixation in various craniofacial trauma reconstructive scenarios.

Rheumatoid arthritis is a chronic systemic autoimmune disease. Although the joints are the major loci of the disease activity, fatigue is a common extraarticular symptom that exists in all gradations of rheumatoid arthritis. Fatigue is defined as a subjective sense of generalized tiredness or exhaustion and has multiple dimensions. Therefore fatigue is a common and frequent problem for those with rheumatoid arthritis. In fact, 88-100% of individuals with rheumatoid arthritis experience fatigue. Especially the degree of fatigue is higher in women than men with rheumatoid arthritis. Despite the importance of fatigue among the patients with rheumatoid arthritis, the mechanism that leads to fatigue in rheumatoid arthritis is not completely understood. This study was intended to test and validate a model to predict fatigue in women with rheumatoid arthritis. Especially it was intended to identify the direct and indirect effects of the variables of pain, disability, depression, sleep disturbance, morning stiffness, and symptom duration to fatigue. Data were collected by questionnaires including Multidimensional Assesment of Fatigue(Tack, 1991), numeric scale of pain, graphic scale of joints, Ritchie Articular Index, Korean Health Assessment Questionnaire(Bae, et al., 1998), Inventory of Function Status(Tulman, et al., 1991), Center for Epidemiologic Studies-Depression, and Korean Sleep Scale(Oh, et al 1998). The sample consisted of 345 women with a mean duration of rheumatoid arthritis for 10.06 years and a mean age of 49.64 years. SPSS win and Win LISREL were used for the data analysis. Structural equation modeling revealed the overall fit of the model. Pain predicted fatigue directly and indirectly through disability, depression, and sleep disturbance. Disability, sleep disturbance predicted fatigue only directly, while depression only indirectly through disability and sleep disturbance. Also morning stiffness and symptom duration predicted fatigue through disability and depression. All predictors accounted for 65% of the variance of fatigue. Depression, pain, and disability predicted sleep disturbance. Depression had reciprocal relationship with disability and they both were predicted by pain directly and indirectly. In summary, pain, depression, disability, sleep disturbance, morning stiffness, and symptom duration contributed to the fatigue of patients with rheumatoid arthritis. The best predictor of fatigue was pain. This finding indicates that the modification of pain, depression, disability, sleep disturbance, morning stiffness could be nursing intervention for relief or prevention of fatigue.

The purpose of this study was to examine the nature of psychopathology and psychosocial environments of children with Atopic Dermatitis(AD) and their relationship to skin symptoms. Seventy outpatients with AD(mean age 9.94, range 4-15 years) and their mothers were subjected to psychiatric interview and parent- and self-report questionnaire(CBCL, MBRI, CDI, Spielberger's State-Trait Anxiety Inventory for Children(STAI), Family Impact questionnaire). Disease severity was assessed in three dimensions(skin extent, disease activity, and subjective symptom) by SCORAD index. Sixteen(22.9%) of our sample were suspected to have behavioral-emotional problems and they were different from non-problem group on depression, trait-anxiety, maternal controlling attitude and negative appraisal of children. While skin inflammation activity was correlated with only trait-anxiety and depression, subjective skin symptoms were correlated with many psychosocial factors such as depression, state-and traitanxiety, family-impact, social competence, internalized and externalized behavioral problem, sexual problem, and mother's positive appraisal of children). We concluded that children with AD are highrisk group for behavioral-emotional problems, and these problems along with maternal negative parenting attitude can affect their subjective symptom experience.

The smart-car industry has emerged as the important variable that will decide the future industrial contour of the automotive industry, together with commercialization of electronic vehicles, connected cars, infotainment, telematics, and the autonomous/self-driving car. This study analyzes the strategic position of platform companies and car manufacturers that would determine the future of the smart-car market. The findings of this study show that despite the entry barriers in industrial factors, such as economies of scale, the industrial infrastructure, and global production networks, and technical factors like exclusive head-sector information, car manufacturers may be deprived of their industrial leadership by platform companies with map and user data, big data capabilities, and user interface experience if they lag behind ICT innovation. This insight is based on the emerging importance of software and platforms, and the simplification of car structures, proven by the successful commercialization of electronic vehicles. This study complements existing studies mainly focused on technical aspects of the smart-car industry by examining the strategic dimensions of platform companies and their approach to the future smart-car market by comparing them with existing car manufacturing multinationals.

The purpose of this study was to assess the level of resilience to burnout and work satisfaction of hospice volunteers. Methods: Participants included 235 regular volunteers at hospice facilities of two university hospitals and four general hospitals located in Busan. The study instruments were the scale of resilience to burnout and work satisfaction. The scale of resilience to burnout consisted of six dimensions (professional competency, accomplishment and worthiness, firm belief and value about their profession, good teamwork, support by their agency, and individual resources) and 31 items which were rated on a 5-point Likert scale, whereas the scale of work satisfaction consisted of 6 items which were rated on a 5-point Likert scale. Data were analyzed by descriptive statistics, t-test, ANOVA, Tukey and Pearson's correlation coefficient. Results: The mean score of resilience to burnout and work satisfaction of participants were 3.59 and 3.69, respectively. The highest and lowest scores of resilience to burnout were individual resources (3.81) and accomplishment and worthiness (3.36). There were significant differences in resilience to burnout scores, depending on religion, health status, type of hospice facilities, and period of volunteer experience. There were significant differences in work satisfaction scores, depending on gender, religion, education level, health status, and type of hospice facilities. Conclusions: Continuous education and efficient management need to be developed to improve the level of resilience to burnout and work satisfaction of hospice volunteers.

Patients' evaluation of hospital care is one of the most important aspects of quality assessment. Survey allows patients to judge sujectively the events that occur during their hospital visit if performed properly. This study describes the result of a research effort to develop outpatient questionnaire that has sufficient validity and reliability to be used to measure patients' perception of satisfaction in Korea and to investigate influencing factors on patients' satisfaction. Self-administered questionnaire was developed for outpatient and the survey was conducted covering 827 outpatients in a tertiary hospital. It was confirmed by factor analysis that patients evaluate several components of ambulatory care distinctly ; hospital environment, administration and ancillary services, and medical care. We found strong evidence of construct validity and internal consistency for the above three dimensions of hospital process. On the contrary, reliability of overall outcome measures was low. It suggests that three items concerning overall outcome measures have some different meanings in patients' perception. Using logistic regression analysis it was found that previous health status, cost evaluation, and improvement in health status have significant influences on the level of patients' overall satisfaction and that patient's sex, experience of previous visit, expectation for improvement, cost evaluation, and improvement in health status are strongly related with intention to recommend hospital. In spite of some limitations the results of this study can be used helpfully as baseline informations for developing self-administered questionnaire and for exploring the influencing factors on patients' satisfaction. Further comprehensive research efforts should be made on the measurement of ambulatory patients' satisfaction and its related factors in current Korean situation.

Pain has at least two dimensions such as somatosensory qualities and affect and patients are frequently asked to score the intensity of their pain on a numerical pain rating scale. However, the use of a undimensional scale is questionable in view of the belief, overwhelmingly supported by clinical experience as well as by empirical evidence from multidimensional scaling and other sources, that pain has multidimensions such as sensory-discrimitive, motivational-affective and cognitive-evaluative The study of pain has recently received much attention, especially in understanding its neurophysiology by using new brain imaging techniques, such as positron emission tomography(PET) and functional magnetic resonance imaging (fMRI), both of which allow us to visualize brain function in vivo. Also the new brainimaging devices allow us to evaluate the patients pain status and plan To treat patients objectively. Base4 on our findings we presented what are the new brain imaging devices and the results of study by using brain imaging devices.

This study was objectively performed to identify dietitians' job in the elderly health-care facilities, to assess facilities and dietitian's demographic characteristics, and to determine performance and importance of dietitian's job including the demand of therapeutic diet development. Survey was conducted by mail and samples were the dietitians working in 376 facilities which capacity is over 50 members from nationwide 583 the elderly health-care facilities. Returned questionnaire was 102 and used for statistic analysis. The distributions of the elderly health-care facilities showed 39 the elderly nursing facilities(38.2%), 32 skilled nursing facilities (32.4%), 13 geriatrics hospital facilities(12.7%) and 9 the elderly cost nursing facilities(8.8%). 60.0 percent of the samples showed its menu price as 1,000 to 1,500 won. A cycle-menu program was in-use at the 79.0% facilities, but only 7.1% facilities have been introduced a selected menu system. 92.9% facilities employed only one dietitian. In the demographic characteristics of dietitian only 14.7% dietitian had a clinical dietitian license and 51.5% of respondents answered at least 1 to 3 months internship program is needed. Job activities of the dietitian in the elderly health-care foodservice were identified as 45 activities with 9 dimensions. Job performance score evaluated dietitian oneself was 4.71 of 7 points. The average importance score that the dietitian evaluated their own job was 5.66 points of 7. The job activities shown higher importance but lower performance were therapeutic diet development for in-patients, menu development suitable for taste of the elderly, and leadership. Job performance score by characteristics of dietitian and their elderly health-care facilities was significantly associated with experience of dietitian in elderly health-care (F=4.480, p<0.05), education of dietitian(F=2.659, p<0.01), number of dietitian(F=2.245, p<0.05), and number of employee in foodservice(F=2.607, p<0.05). Most common diseases of the aged was proved as hypertension(81.7%), diabetes mellitus(71.4%), and dementia(65.0%). The therapeutic diets frequently provided were diabetes mellitus diet, dysphagia diet, low sodium diet, high fiber diet, and high protein diet, in order. For those reasons, dietitian in the elderly health care emphasized that the information about therapeutic diet development such as diabetes mellitus diet, dysphagia diet, low sodium diet and hypertension diet must be continuously developed and provided. The result from this study can be applicable to enlarge and enrich job activities of dietitian in elderly health-care foodservice.

Almost all companies have paid much attention to the safety management ranging from maintenance to operation even at the stage of designing in order to prevent accidents, but fatal accidents continue to increase throughout the world. In particular, it is essential to systematically prevent such fatal accidents as fire, explosion or leakage of toxic gas at factories in order to not only protect the workers and neighbors but also prevent economic losses and environmental pollution. Though it is well known that accident probability is very low in NPP(Nuclear Power Plants), the reason why many researches are still being performed about the accidents is the results may be so severe. HRA is the main process to make preparation for possibility of human error in designing of the NPP. But those techniques have some problems and limitation as follows; the evaluation sensitivity of those techniques are out of date. And the evaluation of human error is not coupled with the design process. Additionally, the scope of the human error which has to be included in reliability assessment should be expanded. This work focuses on the coincidence of human error and mechanical failure for some important performance shaping factors to propose a method for improving safety effectively of the process industries. In order to apply in these purposes into the thesis, I found 63 critical Performance Shaping Factors of the eight dimensions throughout studies that I executed earlier. In this study, various analysis of opinion of specialists(Personal Factors, Training, Knowledge or Experience, Procedures and Documentation, Information, Communications, HMI, Workplace Design, Quality of Environment, Team Factors) and the guideline for construction of PSF were accomplished. The selected method was AHP which simplifies objective conclusions by maintaining consistency. This research focused on the implementation process of PSF to evaluate the process of PSF at each phase. As a result, we propose an evaluation model of PSF as a tool to find critical problem at each phase and improve on how to resolve the problems found at each phase. This evaluation model makes it possible to extraction of PSF succesfully by presenting the basis of assessment which will be used by enterprises to minimize the trial and error of construction process of PSF.

Objectives: This paper is intended to illustrate and to discuss the organization and functioning of community resident groups (CRGs) in a community-based participatory health promotion program for healthy aging. Methods: CRGs were convened in 12 government-subsidized apartment communities for low-income seniors in Pennsylvania, U.S.A., to promote healthy aging. Researchers facilitated CRG meetings following a 6-step process of community empowerment and utilizing a social ecological model for assessment and planning. Almost 200 project-related documents were qualitatively analyzed using matrix analysis principles such as cross-classification of multiple dimensions to identify patterns in the data and matrix building for displaying such patterns. Results: CRGs were venues at which apartment building residents could interact, discuss health priorities, and become change agents in their building. CRG members' community health priorities were about their daily living, including building conditions, poor access to fresh food, and unhealthy resident relations. Specific patterns arose in analysis indicating that leadership withing the CRGs, consistency of meetings and participants' attendance, and ability to link health concerns to daily experience impacted the CRGs' capability to identify and accomplish their goals. Conclusion: Community health issues and solutions to those issues identified by CRGs were unique to community contexts and interests. Consistent participation by community members, a consistent pattern of group activities such as monthly meetings, and having established leadership to manage CRG activities were prominent characteristics of community group functioning.
