To overcome the long design time/high computational effort/low computational performance of phylogenetic learning featuring selection and reproduction, this paper proposes a genetic representation based on XML. Since genetic programs (GP) and genetic operations of this representation are maintained by the invocation of the built-in off-the-shelf XML parser's API, the proposed approach features significant reduced time consumption of GP design process. Handling only semantically correct GPs with standard XML schema can reduce search space and computational effort. Furthermore, computational performance can be improved by the parallelism of GP caused by the utilization of XML, which is a feasible system and wire format for migration of genetic programs in heterogeneous distributed computer environments. To verify the proposed approach, it is applied to the evolution of social behaviors of multiple agents modeling the predator-prey pursuit problem. The results show that the approach can be applied for fast development and time efficiency of GPs.

The call-takers in the 119 General Situation Room are playing important roles in recognizing the first crisis situation such as fire, rescue, and emergency, and in starting up the response system. In particular, with regard to the emergency calls, the prompt and accurate surveillance can determine the patient's life as well as the prognosis. Based on April 8-December 31, 2014 Prehospital Care Reports in a metropolitan city, we analyzed the conversation turns and the conversation time between the agent and the caller, and the time of the conversation structure and sequence according to the reception routes and the severity of symptoms. The conversation analysis between the agent and the caller will be useful for the development and improvement of the action manual in the future.

The fire protection system for high-rise buildings is currently confined to the preparation of sprinklers, emergency stairs, and exit and monitoring systems. On the other hand, an integrated system, including the model with scenario-based actions, is required for effective fire protection. An integrated fire protection system is needed to operate and manage the total cycle of the fire protection. In this study, an integrated fire protection system, which included sensing and consequent processes related to fire emergencies, was designed and implemented. The designed scheme can gather and analyze the data of the production, operation, and consumption patterns as it integrates fire protection systems for fire fighters and evacuating people. The integrated fire protection technology and system, which has target performance with satisfied 1/2 sec transaction response time and 1.2 transactions per second, is expected to contribute to market creation in converged technology-based fire protection fields.

The data analysis system using Big-data is worthy to be used in various fields such as politics, traffic, natural disaster, shopping, customer management, medical care, and weather information. Particularly, the analysis of the momentum of an individual using an acceleration signal collected from a wearable device has already been widely used. However, since the data used in such a system stores only the data necessary for measuring the individual activity, it does not provide various analysis results other than the exercise amount of the individual. In this paper, I propose a system that analyzes collective behavior pattern and activity based on the acceleration signal that can be collected from personal smartphones for 24 hours a day and stored in big data. I also propose a system that sends acceleration signals and receives analysis results using standard messaging to use on various smart devices.

About 1 year and 7 months have passed since the Serious Accident Punishment Act was implemented, and although many studies have been conducted on the definition and policy of the Act, almost no research has been conducted on its impact on the logistics industry. In particular, research on the PDI (PRS) process within finished vehicle logistics is severely lacking ‥‥‥. The government is expecting to expand the scope of punishment and upgrade the safety management system through the Serious Accident Punishment Act, but if you check the industrial accident data issued by the Ministry of Employment and Labor in 2022, the number and rate of industrial accidents will increase compared to 2021

This study analysed the effect of music tempo on young drivers' driving speed. 23 male college students under age 26 were randomly assigned to one of three music conditions as follows; No Music, Slow Music and Fast Music. Every subject's travel time(sec) and driving speed(Km/h) was recorded while they were driving a computer-based driving simulator. As the results of this study, we found that 1) the fast music group's mean of travel time was the shortest and also, 2) their mean of driving speed was the fastest. The effect of music tempo on driving speed can be explained as a biological mechanism, same as the effect on our heart-beat rate or intensity of physical exercising. This result shows us that listening musics while driving can affect the driving speed instead of the driver's physical condition.

The purpose of this study was to identify the service encounter blueprint by types of restaurants in order to manage moment of truth when customers who visit a restaurant encounter services. The service encounter blueprint gives an overall picture of the service provision to visualize an entire service process and its integrated structure. The blueprint is used for service process analysis technique. The random samples of 15 customers were observed by types of restaurants and the records were collected for three-days' observation. Interviews were performed by 3 managers, 3 service encounter employees, 3 cashiers, 3 cooks and 10 customers by types of restaurants. After drawing the first service blueprint, it was revised by the interview with the 3 managers and 6 service encounter employees. In this paper, restaurant service processes are reviewed and analyzed. By use of service blueprint, the processes are analyzed to find a fail point, customer wait, employee decision. As a result of making a blueprint of service encounter by types of restaurant, blueprints of fine-dining restaurants and family restaurants were similar, while fast-food restaurants showed a little difference. In particular, difference was indicated in a point where interaction of service encounter occurred. Difference was indicated depending on types of restaurants. Therefore, the efforts to improve this problem were needed. The blueprint is a map or flowchart (called a process chart in manufacturing) of all transactions constituting the service delivery process. The results showed that service encounter blueprint can be used to improve the service process in the restaurant's encounter.

The purpose of this study is to systematically develop an impression management education program for career women by applying the Educational System Development Model [ESD] (Kwon, 1997) based on the research results of Hwang and Lee(2019) on social attractiveness. Since the previous impression management education programs were generally developed by content experts, few of them were developed systematically by considering the learner characteristics, clearly setting the educational goals, and structuring the contents accordingly. In this study, 'social attractiveness' defined by Hwang and Lee (2019) was considered as the educational goal of the impression management education program. In particular, this study focused on the design stage of the ESD model, set teaching goals based on the components of social attractiveness derived from previous studies, and conducted an analysis of teaching activities, the establishment of the educational goals at the specific function level, allocation of time, and establishment of an evaluation plan. The research process was intended to improve the learners' social image directly related to success through a systematic educational program designed to enhance the social attractiveness of working women with various hands-on activities and information. The impression management education program designed in this study has the educational advantage of a learner-centered education program configured to meet the needs and goals of career women. In addition, based on the ESD model, the sub-factors necessary for impression management were identified, and the curriculum was configured to reflect them through mutual communication between the instructor and learners. Therefore, this education program meets the basic requirements of impression management education necessary for career women and is expected to contribute to enhancing the social attractiveness of working women.

Based on recent dramatic increases in foodborne outbreaks in restaurants, self-managed sanitation systems are now recommended to control contributing risk factors. This study aimed to improve sanitation management practices in restaurants and had two objectives. First, we tried to develop a self-managed sanitation check-list, including risk factors contributing to foodborne illness and Korean food hygiene regulation articles. We also tried to evaluate current sanitation management practices in restaurants according to operation and restaurant type. Thirty restaurants were evaluated by on-the-spot inspectors using an auditing tool consisting of four dimensions, seventeen categories, and forty-one items. Total compliance rate categorized by operation type significantly differed between chain restaurants and self-managed restaurants, with values of 85.5% and 51.6%, respectively. Therefore, self-managed restaurants, which showed the lowest compliance rate of below 30.0%, need more strict control to improve current unsanitary management practices, specifically relating to 'sterilization of knives, chopping boards, and wiping cloths', 'sanitation training', 'not allowing access into the kitchen to outsiders', 'handling of food or utensils on shelves at a 15 cm distance away from floor', 'prevention of cross-contamination of cooked foods or vegetables', and 'records of kitchen access or inspection'. Thus, an effective food sanitation system is essential and should be implemented to improve the existing sanitary conditions in restaurants. However, the most important factor to achieving food sanitation management objectives is food handlers' self-motivation.

Purpose: Koreans' internet and smartphone usage hours are steadily increasing and the dependence of young people on smartphones is causing social problems. Therefore, this study was conducted to examine health and dietary habits, as well as hair mineral contents according to the level of dependence of smartphone use among adolescents to clarify the interrelation of smartphone dependence, lifestyle, dietary behavior, and mineral nutrition status. Methods: A total of 80 smartphone-addicted adolescents participated in this study and were divided into three groups (general, potential and danger group) according to smartphone dependence. The subjects' lifestyles and dietary behaviors were then surveyed, and hair mineral contents were analyzed. Results: Higher smartphone dependence was associated with lower average weekly sleeping time and later first smoking age. In the danger group, the rate of eating fast and the rate of snacking twice a day was also relatively high. Parents (45.0%) and mobile (30.0%) were the factors having the greatest influence on an individual's dietary behavior. In the hair mineral analysis, all subjects had lower selenium concentrations and higher lead concentrations than normal. In addition, the levels of aluminum in the danger group were higher than in the normal range and the highest among the three groups. Conclusions: It is necessary to guide adolescents to use smartphones correctly and manage dietary habits. In addition, careful attention is needed the mineral nutritional status of smartphone-addicted adolescents.
