Purpose - The convenience store business sector in South Korea has contributed to economic growth and job creation, and the growth potential of this market segment remains very high. In addition, service value is a more important factor than price in determining purchase intention. Research in the convenience store market is relatively very low compared to other retail sectors. In particular, research on service quality for the convenience of retailers who examine and analyze customer behavior and service quality factors used in the convenience store side of the situation is very inadequate. We have investigated the relationship of store service quality, service satisfaction, and store loyalty. In addition, we have examined the way service value moderates the relationship among these variables. Research design, data, and methodology - The questionnaire was developed using modified and supplementary questions based on the KD-SQS and RSQS models. The study suggested a theoretical model composed of 15 hypotheses on the relations between theoretic variables, and surveys conducted with consumers in discount stores in the Seoul and Gyunggi Metropolitan area in order to verify the hypotheses. We used the SPSS/PC statistical packages to analyze the results. The number of surveys used was 227. Moreover, a structural equating model was also used to analyze the reliability and validity of the composing elements and to verify the suggested hypotheses. Results - The overall results of this study are as follows. First, all service quality elements have a significant effect on service satisfaction. Second, all service quality elements have a significant effect on store loyalty. Third, service satisfaction has a significant effect on store loyalty. Finally, when the participants were divided into high and low service value the results of the multiple regression analyses showed that only the relationship between policy of service quality and satisfaction, and human interaction and policy of service quality and loyalty were significant. The implications are discussed based on the findings of the study. Conclusions - First, through direct hypotheses testing, we confirmed that the convenience service quality positively impacts the service satisfaction and loyalty of buyers. In particular, the reliability, origin benefit, and promotion were found to have more influence on satisfaction and loyalty of consumers of a convenience store. Further, for the service quality of the convenience for the consumer loyalty, greater human interaction was a high-value and statistically significantly higher than the degree of improvement in consumer loyalty. This underscores the importance of education and human services management of employees working in a convenience store. In particular, frequent changes in personnel generate results that negatively impact loyalty with customers. These results may lead to a serious problem in the economics of the store. Therefore, it should enhance the value of services through the establishment of training and compensation for employees. In addition, a certain educational level is required as well as a basis for compensation and retention.

Background: Police officers' stress perception, frequency of stressful events (stressors), and police work characteristics may contribute to poor sleep quality through different mechanisms. Methods: We investigated associations of stress severity (measured by stress rating score) and frequency of stressors with sleep quality and examined the influence of police work characteristics including workload, police rank, prior military experience, and shift work on the associations. Participants were 356 police officers (256 men and 100 women) enrolled in the Buffalo Cardio-Metabolic Occupational Police Stress Study from 2004 to 2009. A mean stress rating score and mean frequency of stressors occurring in the past month were computed for each participant from the Spielberger Police Stress Survey data. Sleep quality was assessed using the global score derived from the Pittsburgh Sleep Quality Index survey. Linear associations of the stress rating score and frequency of stressors with sleep quality (Pittsburgh Sleep Quality Index global score) were tested. Age, sex, race/ethnicity, and smoking status were selected as potential confounders. Results: The stress rating score was positively and independently associated with poor sleep quality (${\beta}=0.17$, p = 0.002). Only workload significantly modified this association (${\beta}=0.23$, p = 0.001 for high workload group; p-interaction = 0.109). The frequency of stressors was positively and independently associated with poor sleep quality (${\beta}=0.13$, p = 0.025). Only police rank significantly modified the association (${\beta}=0.007$, p = 0.004 for detectives/other executives; p-interaction = 0.076). Conclusion: Both police officers' perception of stress severity and the frequency of stressors are associated with poor sleep quality. Stress coping or sleep promotion regimens may be more beneficial among police officers reporting high workloads.

Violinists learn to make better sounds by hearing and evaluating their own playing though numerous practice. This study proposes a new method of auditory feedback, which mimics this violinists' step and verifies its efficiency using experiments. Making the desired sound quality of a violin is difficult without auditory feedback even though an expert violinist plays. An algorithm for controlling a robot arm of violin playing robot is determined based on correlations with bowing speed, bowing force, and sound point that determine the sound quality of a violin. The bowing speed is estimated by the control command of the robot arm, where the bowing force and the sound point are recognized by using a two-axis load cell and a photo interrupter, respectively. To improve the sound quality of a violin playing robot, the sounds information is obtained by auditory feedback system applied Short Time Fourier Transform (STFT) to the sounds from a violin. This study suggests Gaussian-Harmonic-Quality (GHQ) uses sounds' clarity, accuracy, and harmonic structure in order to decide sound quality, objectively. Through the experiments, the auditory feedback system improved the performance quality by the robot accordingly, changing the bowing speed, bowing force, and sound point and determining the quality of robot sounds by GHQ sound quality evaluation system.

In a service process, the customer typically experiences two types of interactions; one is interaction with the physical ambiance (servicescape) and the other is with employees who may be responsible for the service process quality. The literature in general supports that process quality is a critical determinant for overall service quality and customer satisfaction. In this paper, we primarily examine how the servicescape intervenes the association between process quality and employee/customer satisfaction. The proposed models are tested. using the data collected from the major golf courses in Korea. The results suggest that improving process quality and servicescape have a positive influence on employee/customer satisfaction directly and/or indirectly, but the effect of servicescape may be stronger in the case of golf course businesses. Servicescape also contributes to improving process quality by enhancing employee satisfaction. These results collectively indicate that management emphasis on improving service quality without renovating physical surroundings may results in unsatisfactory outcome.

While many services appear, it are performed in the various researches about a service. Among them, as to the basic reason for measuring the service level, in order to find out the strategy improving service quality. But the method for measuring quality of services up to date was unable to make it enough the role. This research tried to propose the approach systematically analyzing the human errors in order to improve service quality about the call center which utilizes the information technology. In fact, the human errors was found in the customer contact point in which the actual service is delivered. An interaction between the element for comprising call service was classified into 3 while defining the human error as 3 group. Moreover, the process where a service is delivered was classified according to 5 step and the generated error was measured in each step. The implication of this research looks at the service failure and dissatisfaction as the occurrence of the human errors and illustrates the service quality improvement as a correction or a reduction. This approach is used that service is materially easily understood and is formulated with the quality improvement strategy.

VR (Virtual Reality) contents make the audience perceive virtual space as real through the virtual Z axis which creates a space that could not be created in 2D due to the space between the eyes of the audience. This visual change has led to the need for technological changes to sound and sound sources inserted into VR contents. However, studies to increase immersion in VR contents are still more focused on scientific and visual fields. This is because composing and producing VR sounds require professional views in two areas: sound-based engineering and computer-based interactive sound engineering. Sound-based engineering is difficult to reflect changes in user interaction or time and space by directing the sound effects, script sound, and background music according to the storyboard organized by the director. However, it has the advantage of producing the sound effects, script sound, and background music in one track and not having to go through the coding phase. Computer-based interactive sound engineering, on the other hand, is produced in different files, including the sound effects, script sound, and background music. It can increase immersion by reflecting user interaction or time and space, but it can also suffer from noise cancelling and sound collisions. Therefore in this study, the following methods were devised and utilized to produce sound for VR contents called "A Midsummer Night" so as to take advantage of each sound-making technology. First, the storyboard is analyzed according to the user's interaction. It is to analyze sound effects, script sound, and background music which is required according to user interaction. Second, the sounds are classified and analyzed as 'simultaneous sound' and 'individual sound'. Thirdly, work on interaction coding for sound effects, script sound, and background music that were produced from the simultaneous sound and individual time sound categories is done. Then, the contents are completed by applying the sound to the video. By going through the process, sound quality inhibitors such as noise cancelling can be removed while allowing sound production that fits to user interaction and time and space.

Purpose: Many studies have shown that regular exercise produces positive effects on health. The purpose of this study was to examine the differences of health-related quality of life by stage of exercise and the interaction effect of age, sex and stage of exercise. Method: A total of 1266 participants were interviewed with structured questionnaire. Stage of exercise was assessed with a single item and respondents were classified with respect to exercise intention and behavior. Health-related quality of life was measured with SF-36 Health Survey Questionnaire. Result: Health-related QOL were found to be different by stage of exercise. The subjects who were reached maintenance stage showed significantly higher scores on physical functioning, bodily pain, general health perception, mental health, role limitation due to emotional problems, social functioning, and vitality than those in preparation, contemplation, and precontemplation stage. In addition a significant interaction effect between stage of exercise and age was found on physical functioning, bodily pain, general health perception, mental health, and vitality. Conclusion: Perceived health-related QOL varies with stage of exercise. This finding suggests that health is related to both intention and behavior of exercise. Therefore it is important to consider cognitive-motivational and behavioral stage of change for developing exercise programs.

Objectives: This study was performed to examine the effects of storage time and temperature and their interaction on the hygienic quality parameters of shell eggs. Methods: Eggs from 40-week-old Hy-Line Brown hens were sampled immediately after being laid and subjected to storage periods of four weeks at a refrigerated temperature ($4-5^{\circ}C$) or room temperature ($13.0-19.7^{\circ}C$). Interior/exterior qualities were examined every one week. Results: Weight loss was 2.4-3.1%. The initial specific gravity of the eggs was maintained until one week at both temperatures. Air cell size exceeded 4 mm when stored for one week at room temperature, and two weeks at refrigerated temperature. Albumen index and Haugh unit were significantly decreased at both temperatures after one week (p<0.001). Rapidly increased pH of the albumen with one week of storage was observed, regardless of temperature (p<0.001). Extension of the storage for up to four weeks at room temperature resulted in remarkable deterioration of eggshell quality and instrumental color as redness (a). Air cell size, albumen and yolk indices, Haugh unit, pH of albumen and yolk were found to be influenced by storage time and temperature (p<0.001). Interaction effects between storage time and temperature were also significant for air cell size, pH of albumen and yolk (p<0.001). Conclusion: The results suggest that air cell size and pH of albumen and yolk were important parameters influenced by storage time and temperature in shell eggs. Storage time was more influential for air cell size, and temperature for the pH of yolk. Both variables almost equally influenced the pH of albumen.
