The etiopathogenesis of burning mouth syndrome (BMS) seems to be complex and many patients probably involves interactions among local, systemic, and/or psychological factors in the pathophysiologic mechanism. Although there are controversies over whether the psychological factor is a cause or a result of BMS, several studies have supported strong relationships between psychological factors and chronic pain. It has been suggested that somatic complaints from unfavorable life experiences may influence both individual personality and mood changes; however, initiation of BMS symptoms is not necessarily correlated with stressful life events despite their elevated psychological stress. If the psychological distress is not a causal factor of BMS, it seems that BMS patients may be particularly vulnerable to psychological problems, primarily depression, anxiety, and hostility due to the characteristic entities of BMS such as chronic persistent pain itself. It seems likely that both physiological and psychological factors play a role in causing, perpetuating and/or exacerbating BMS; therefore, both two components of the patient's symptoms must be addressed. The acceptance of psychological factors by the patient is often an important element of BMS, management. The evaluation of psychological and emotional status of BMS patient enables clinicians to recognize prolonged negative and subclinical factors which can complicate the management of pain or indirectly perpetuate other physical factors. This evaluation improves the doctor-patient relationships, motivation, and compliance through a correct understanding of the clinical problem. Appropriate emotional and psychological evaluation may be required prior to developing a treatment plan in order to gain the successful treatment outcome.

The Development of a new menu item in a restaurant usually begins when your chef prepares a creative "brainchild" that he serves to you, the owner. If you are satisfied with the new dish, It gets a "go-ahead" signal, under the assumption that what appeals to you will appeal to a significant number of your customers. While many excellent and successful items have been created this way, It is not reasonable to expect that your tastes can represent the wide variety of your potential guests tastes. The purpose of this study is to examine the factors that have an influence on customers′ menu evaluation. A menu is a marketing tool which delivers restaurant′s image and message to customers needs and wants to restaurant. So far, studies on menu have been done in an analytical way from a management′s viewpoint and inadequate to reflect customers′ needs and wants. In this study is to examine the factors that have an influence on customers′ menu evaluation. The factors affected the customers′ menu evaluation of hotel restaurant in the three factors. Three factors are food service factor, menu copy factor, value of food. Correlation between the evaluation of criteria and selection of menu was examined.

Lithium-ion batteries (LIBs) have attracted much interest for their high energy density (>150 mAh/g), high capacity, low self-discharge rate, and high coulombic efficiency. However, with the successful commercialization of LIBs, fire and explosion incidents are likely to increase. The thermal runaway is known as the major factor in battery-related accidents that can lead to a series of critical conditions. Considering this, recent studies have shown an increased interest in countering the safety issues associated with LIBs. Although safety standards for LIB use have recently been formulated, little attention has been paid to the safety around the manufacturing process for battery products. The present study introduces a risk assessment method suitable for assessing the safety of the LIB-manufacturing process. In the assessment method, a compensation parameter (Z-factor) is employed to correctly evaluate the process's safety on the basis of the type of material (e.g., metal anode, liquid electrolyte, solid-state electrolytes) utilized in a cell. The proposed method has been applied to an 18650 cell-manufacturing process, and three sub-processes have been identified as possibly vulnerable parts (risk index: >4). This study offers some crucial insights into the establishment of safety standards for battery-manufacturing processes.

P corporation co-developed with Google and implemented smart work system called SWP for the purpose of 'communication and collaboration with co-workers' beyond the general goal of increasing productivity and comfort of employees. The primary objective of this study is to objectively analyze the influence of the effect factor from end user's perspective and user satisfaction on SWP usage, intention for continuous usage and individual performance. To accomplish this research purpose, this study established research models and hypothesis by collective review about information system success models, and tested the research hypotheses using the structural equation modeling technique by data collected from 320 SWP system users of P corporation. Variations for system satisfaction evaluation standard are 1)SW system usage 2) intention for continuous usage 3) individual performance, effect variations are 1) social factors 2) technical factors 3) combination of social and technical factors. Therefore, this study is about influence factors on success of SWP system and how the factors impact the outcome. The test results of this research model is summarized as follows. Firstly, system user's satisfaction had positive impact on all three; SWP system usage, intention for continuous usage and individual performance. Secondly, social factor 'SWP control system' and technical factor 'information quality' and 'system quality' had positive impact on SWP system user satisfaction, while social factor 'shared value' and technical factor 'service quality' did not have significant effect on user satisfaction. Shared value however, had interactive effect with 'information quality' and 'service quality'. This study is expected to contribute to spread of academic research on smart work system by suggesting a model that can show important factors for corporation while explaining the successful implementation of SWP and its continuous usage.

Purpose: The aim of this study was to evaluate the validity and reliability of the Korean version of the Person-centered Care Assessment Tool (P-CAT). Methods: The English P-CAT was translated into Korean with forward and backward translation. Survey data were collected from 458 staff in 17 long-term care facilities in Korea. Construct validity and criterion related validity were evaluated. Cronbach's alpha was used to assess reliability. Results: The Korean version of P-CAT was shown to be valid homogeneously by factor, item and content analysis. Internal consistency reliability was satisfactory in which the values of factor 1, factor 2 and the total scale were .84, .77 and .86 respectively. Exploratory factor analysis supported the construct validity with a two-factor solution. Factor loadings of the 13 items ranged in .34~.80. Criterion validity to the Person-centered Climate Questionnaire-staff (PCQ-S) was .74 (p<.001). Conclusion: The Korean version of the P-CAT was found to be an applicable instrument with satisfactory reliability and validity for further use in measuring successful person-centered care in long-term care facilities for older persons.

Perichondrium is generally used for reconstruction of airway and successful regeneration of cartilage framework using perichondrium are reported by several authors. It has many advantages for airway reconstruction. It can maintain the stable framework and it has higher flexibility so it's easy to design according to the shape of defects. It resist strongly against infection process. Its airtightness and rapid mucosalization enables to predict good postoperative recovery and results. To investigate the differences in cartilage regeneration between avascular and vascularized perichondrial flap, this study was designed with vascularized flaps composed of vascularized perichondrium and central auricular artery and vein. Morphologic study was performed to determine the fate of the grafted perichondrium at regular intervals using light microscopy with H & E stain. Chondrogenic potential and formation of cartilaginous plate of experimental group was superior than in the control group. Grafted perichondrium was fed by consistent feeding vessel. At 6 weeks, the regenerated cartilage could hardly be distinguished form the normal cartilage framework but in control group, regenerated cartilaginous tissue was generally immature in same period. In conclusion, this study indicated that consistent vasculature to grafed tissue is the essential factor for successful reconstruction of cartilaginous framework.

The purpose of this paper is to examine the possibility of whether B2B e-marketplaces continue to grow. There are numerous barriers to the growth of e-marketplace, but certain key factors can push e-marketplaces beyond these obstacles. In the stage of generating traffic, it is essential to find a vertical area to attract buyers and sellers which can generate B2B transaction through e-marketplace. Generating traffic is possible only for e-marketplaces established by those who have vertical knowledges and strong off-line relationship in the vertical areas. In the stage of concentrating traffic, more attention should be given to reach critical mass and to increase transaction through e-marketplace. Currently, there seems to be a tendency that having major buyers as members of a e-marketplace is an true factor for the successful e-marketplace. Finally, to attain the locking traffic, e-marketplace needs to have the ability to generate revenue through B2B transaction. What we have learn from this study is that having the software-technology is not a sufficient condition to successfully operate B2B e-marketplace. It is important for e-marketplace to attract major players in order to increase B2B transaction, and also to make profit by them.

Organizations in some industries are still hesitant to adopt the Enterprise Resource Planning (ERP) system due to its high risk of failures. This study examined how industry classification affects the successful implementation of the ERP system. To achieve this goal, we reinvestigated the existing ERP Success Model that was developed by Chung with the data from various industry sectors, since Chung validated the model only in the engineering and construction industries. In order to test to see if the Chung model can be applicable outside the engineering and construction industries, the relationships between the ERP success indicators and the critical success factors in the Chung model and those in the sample data collected from ten different industry sectors were compared and investigated. The ten industry sectors were selected based on the Global Industry Classification Standard (GICS). We found that the impact of success factors on the success of implementing an ERP system varied across industry sectors. This means that the success of ERP system implementation can be industry-specific. Thus, industry classification should be considered as another factor to help IT decision makers or top-management avoid ERP system failures when they plan to implement a new ERP system.
