This study was designed to identify a subjective symptom level by Indoor air according to ventilation system in Dental Clinic. The number of respondents was 582 who work in dental clinic and period of investigation was October 2010 through January 2011. A structured questionnaire was employed to evaluate the level of participants' sociodemographics, job-related factors, work place condition, a subjective symptom. Most of respondents were answered that time for symptom to begin was at around 2 P.M. and time for symptom to feel serve pain was at around 3 P.M. and ventilation frequency per a day was often in case of individual cooling and heating system. More often natural ventilation and in case of individual cooling and heating system, the level of subject symptom was low and multiple regression analysis has found that indoor air quality related elements were main factors that influence to the feeling of satisfaction in work place. The results of this study suggest that more often natural ventilation was very important to reduce the level of subjective symptom. Thus, a management program for indoor air quality is strongly recommended by natural ventilation, maintenance man for promotion of quality of life in dental hygienist and to improve dental service and competitiveness.

The purpose of this study is to examine the current status of automobile logistics in the domestic automobile industry and to derive and evaluate the factors to improve the quality of automobile logistic services to final consumers. To that end, we selected the relevant factors through literature review and expert interviews, and conducted a survey with consumers and experts. The quality of automobile logistic service was evaluated using the Importance-Performance Analysis (IPA) method. The results show that the "kindness of shipping staff" is high on the importance of customers but low on the importance of employees. On the other hand, factors that have high customer satisfaction but low staff satisfaction include "rapid handling of complaints", "transportation accuracy of receipt", "kindness of delivery staff", and "automobile manual guide and explanation of internal functions". This study has academic and industrial significance in that it has derived important factors for evaluating the quality of automobile logistics services and suggests improvement measures for experts and consumers who actually work in the industrial field. Future research should investigate measures to minimize the returns and complaints of shipment offices which have not been examined in this study.

In order to avoid the spread of Covid-19, outdoor activities are decreasing worldwide and the time spent at home is increasing. As physical activity declines, the number of people who feel bored, restless and immune deficient is increasing. As indoor life becomes more permanent, multiple approaches to home workout are becoming active. This paper examines how the Covid blue (boredom and social anxiety) produced in the no-touch era affects quality of life through the use of home training applications. Questionnaires were collected from Chinese people using a website dedicated to Chinese questionnaires, and finally 383 appropriate data were analyzed using SPSS24.0 and AMOS24.0. The research results showed that the actual experience of using home workout had a positive impact on quality of life. The higher the user's sense of social unease about being late in the untact, It was found that the higher the social anxiety perceived by users about the untact era, the higher the interactivity and exercise satisfaction with the home workout app. Home workout application can improve exercise satisfaction and quality of life, which are more positive effects beyond the result of resolving consumers' boredom. Therefore, it can be used as a channel for digital services.

This study, targeting Korean tertiary hospitals and general hospitals, aims to analyze how value chain model in health and medical institution suggested by Duncan and else influences on hospital management. A survey was conducted to verify the actual proof analysis of this study model. 880 questionnaires were distributed to entire 88 hospitals and 739 copies were returned from 76 hospitals. This study mainly consists of three steps to analyze the effect value chain activity has on management performance of general hospitals. For the first step, we analyzed the effects service delivery activity has on management performance. For the second step, we analyzed the effects service support activity has on management performance and for the third, we analyzed the effects interaction between service delivery activity and service support activity has on management performance. The main results of this study are as follows. First, in terms of the management performance of scale, the factors which influenced on daily charge of outpatient were service activity before treatment, at the moment of treatment and value chain activity, while more important factors in daily charge of inpatient were organizational culture, organizational structure and value chain activity. In terms of management performance of quality, the factors which influenced on the first medical examination rate of outpatient were service activity before, at the moment of and after treatment, while activity at the moment of treatment, organizational structure, and value chain activity which is interaction were more important factors in average length of stay. In terms of non-financial performance, the management performance factors which influenced on job satisfaction were service activity at the moment of, after the treatment and value chain activity, while organizational culture, strategy resources and value chain activity which is interaction were more important factors in job commitment. Secondly, all the service support activity, service delivery activity and value chain activity had statistically significant effect on management performance. Among the three factors, service support activity had relatively high effect than others.

Network resilience provides an effective way to overcome the problem of network failure and is crucial to Internet protocol (IP) network management. As one of the main challenges in network resilience, recovering from link failure is important to maintain the constancy of packets being transmitted. However, existing failure recovery approaches do not handle the traffic engineering problem (e.g., tuning the routing-protocol parameters to optimize the rerouting traffic flow), which may cause serious congestions. Moreover, as the lack of QoS (quality of service) restrictions may lead to invalid rerouting traffic, the QoS requirements (e.g., bandwidth and delay) should also be taken into account when recovering the failed links. In this paper, we first develop a probabilistically correlated failure model that can accurately reflect the correlation between link failures, with which we can choose reliable backup paths (BPs). Then we construct a mathematical model for the failure recovery problem, which takes maximum rerouting traffic as the optimizing objective and the QoS requirements as the constraints. Moreover, we propose a heuristic algorithm for link failure recovery, which adopts the improved k shortest path algorithm to splice the single BP and supplies more protection resources for the links with higher priority. We also prove the correctness of the proposed algorithm. Moreover, the time and space complexity are also analyzed. Simulation results under NS2 show that the proposed algorithm improves the link failure recovery rate and increases the QoS satisfaction rate significantly.

Objectives: To determine the factors affecting the assessment of Oriental medical institutions under the Oriental Medical Institution Assessment System and thereupon, provide for some basic data and alternative measures for assessment of Oriental medical institutions. Methods: The researcher sampled 320 people employed by 26 Oriental medical institutions designated as model Oriental medical institutions subject to assessment in 2008 and 2009 and thereupon, used a structured and open-ended survey table for them to collect the data. The size of the final sample was n=302. Results: The Oriental medical institution staff were highly aware of the Oriental medical institution assessment (OMIA), After adjusting the other factors by multiple regression, the factors affecting such recognition were different significantly depending on age (those in their 30's), types of job (nurses and treatment assistants) and locations of hospital (GyeongSang-do). The staff expected the OMIA could helpful for improving facilities and system of hospitals, thus promoting satisfaction of patients. To do so, they felt it necessary to develop an assessment scale reflecting the special conditions besetting the Oriental medical institutions as well as the indices for improvement of Oriental medical service quality. Conclusion: It is hoped that this study will be followed up by future studies which will comparatively analyze Oriental medical institution staff's perception of the assessment system before and after its operation and thereby, suggest some ideal policy alternatives for assessment of the Oriental medical institutions. Furthermore, future studies are requested to research into Oriental medical institution staff's needs and consumers' needs as well in consideration of the characteristics of the Oriental medical institutions and thereupon, suggest some alternatives for continued education, development of the assessment tools, methods and policies.

As mentioned above, Korean restaurant's menu price is to be decided by combining various factors. Korean restaurant is demanded to decide menu price more carefully than other restaurants do, because the number of Korean restaurant is the largest in Korea and Korean food is the most popular among the Korean people. Korean restaurant cannot neglect price competitiveness and is often given complaints from its customers. Because of such management difficulties, the number of Korean restaurant has recently decreased at special class hotels as well as common hotels. Korean restaurant managers are demanded to make efforts to inherit Korean tradition and culture by keeping pride and responsibility. Until now, Korean restaurants are thought to decide the menu prices in short-sighted, non-scientific and haphazard way of thinking. Such price decision factors have established traditions and have been generally accepted to let Korean restaurant managers lose carefulness at the menu price decision. In advanced countries, however, they recognized the importance of the price decision since the 1960's or earlier to research the menu price systematically and scientifically. Before deciding the menu prices, Korean restaurant managers are demanded to investigate various kinds of factors carefully and spend a lot of time to calculate direct costs, that is, one of the most important factors of cost calculations. The managers are demanded to decide the menu prices in reasonable and future-oriented way by keeping not private thinking but correct information and judgment. The sale of each menu has difference, while the menu price increase has been evaluated to be successful from overall point of view. Despite of increased total sale, there was not much difference of net profit because of increased material costs. However, higher level of the customers produced comfortable and cozy atmosphere of the restaurant enough to satisfy customers, and improved service quality much more. Not only customer satisfaction but also improved service quality is thought to play an important role in invitation of future customers.
