This study was intended to suggest the future direction of catering companies in line with the new normal in the era of COVID-19. The purpose of this study is to investigate the effect of image and awareness of signs for safe restaurant on behavioral intentions. As a result of testing the hypothesis, first, it was found that the image of the sign for the safe restaurant had a significant effect on the recognition. Second, the image of the safe restaurant sign has a significant effect on trust. Third, it was found that the awareness of the signs for the safe restaurant had a significant effect on trust. Fourth, trust had a significant effect on behavior intention. Fifth, it was found that the image and awareness of the sign in the safe restaurant did not have a statistically significant effect on the behavioral intention. Sixth, it was found that the image of the sign at the safe restaurant and the awareness of the sign at the safe restaurant completely mediate trust and have a significant effect on the behavioral intention. The results of this study show the need for publicity activities to raise awareness of the safe restaurant certification and the importance of giving trust to consumers.

This study was carried out to obtain baseline data on the causes of industrial accidents and their prevention by investigating structural models between the Shipyard workers' egogram ego-states (CP: Critical Parent, NP: Nurturing Parent, A: Adult, FC: Free Child, AC: Adapted Child), safe and unsafe behaviors, and industrial accidents (frequency/severity). In order to achieve this goal, 378 workers from 3 locations of major corporations in Geojedo Island and Ulsan took a questionnaire, which was then analyzed with a structural equation model using the SPSS 23.0 and AMOS 24 statistics package, and the main results of the study are as follows. First, NP and A's ego-states had a positive influence on safe behavior, AC's ego-state had a negative influence on safe behavior, and A's ego-state had the largest influence on safe behavior. Second, CP and AC's ego-states had a positive influence on unsafe behavior, and A's ego-state had a negative influence on unsafe behavior. AC's ego-state had the largest influence on unsafe behavior. Third, safe behavior did not have a significant influence on industrial accidents. However, unsafe behavior had a positive influence on industrial accident frequency and industrial accident severity, both sub-factors of industrial accidents. This study, despite its limitations, such as sampling limitations, has the following significance. First, this study verified that ego-state, a psychological characteristic, is an important factor for predicting unsafe behavior that induces industrial accidents. Second, in order to reduce industrial accidents, there is a need to stimulate the A ego-states, and promote continuous safety management and safety education to neutralize the AC ego-state. Third, previous studies were limited in the area of practical methods for reducing unsafe behaviors, but this study presents practical methods for reducing unsafe behaviors by verifying the structural relationship between safe/unsafe behaviors and industrial accidents by selecting ego-gram ego-states, variable personality theory, as an independent variable.

This study examined the effect of Behavior Based Safety(BBS) program on safe behaviors of bus drivers and passengers. Four male bus drivers working at a H transportation company situated in Seoul participated in this study. BBS program consisted of education, prompts, and self-monitoring with goal setting. Dependent variables were the percentage of two safe driving behaviors of bus drivers (departure after stopping for 3 seconds, announcement for holding bus handles) and the percentage of one safe behavior of passengers getting on the busses those drivers drove (holding bus handles). A primary observer and two trained assistant observers measured two safe behaviors of the bus drivers with behavior checklists by riding on the busses and the passengers' safe behavior was observed by CCTV installed on each bus. An ABC multiple baseline design across participants was adopted. After baseline(A), education and prompts(B) and self-monitoring with goal setting(C) were introduced sequentially to each participant. The results showed that BBS program was effective to increase both bus drivers' and passengers' safe behaviors. Especially self-monitoring with goal setting was more effective in improving safe behaviors of bus drivers than education/prompts. These results suggest that education/prompts and self-monitoring with goal setting would be an alternative treatment technique to improve safety for lone workers such as bus drivers.

The purpose of this study is to develop the evaluation system of which the city safety can be realized in the U-City. The evaluation system on "how much safe the present city is" and "how much safe it will be in the future" has been selected and the criticality has also been analyzed. The result of criticality analysis is that the indicator for "how safe the current city is" showed that the disaster prevention and environmental field are important. In the future, the indicator of possibility for the U-safe city should be prepared by the imtegrative operation management system, and on the basis of this, it also showed that the necessary indicator to build the system for keeping the safe city is important. The evaluation system for the U-safe city, hereafter, can be utilized for the city plan, construction, operation, and management utilized by IT in local government.

In this study, the summary and characteristics of WHO International Safe Community are examined and the activities for the establishment of safe city were analyzed targeting Samcheok City in Gangwon-do which prepares for the certification of the International Safe Community. And, based on the result, this study intends to present the direction of establishment and development of international safe city to improve the regional safety. First, for the establishment of safe city, measures and programs for vulnerable classes and accidential forms in the area must be developed and operated continuously. Second, continuous and systematic activities must be done by establishing combined network between regional government association and relative organ and resident association in the area. Third, public policies for establishing safe city so as to improve regional safety, such as enactment of relative si/do ordinance, etc, must be prepared so as to operate it systematically. Finally, through the various activities by establishing international network, education, publicity activities and various informations must be acquired.

In the present paper, the analysis is on the safe navigation between ships moving each other in restricted waterways under the external force, such as wind or current The numerical simulation of manoeuvring motion was carried out to propose an appropriate safe speed and distance between ships, which is required to avoid marine disasters from the viewpoint of marine safety. From the inspection q this investigation, it indicates the following result In case of proximal navigation between ships under the wind and current, the low-speed vessel is potentially hazardous because the rudder force if low-speed vessel needed for steady-state course-keeping is not sufficient, compared to the high-speed vessel The manoeuvring characteristic based on this investigation will be very useful for keeping the safety of navigation from the practical point of ships design and traffic control in restricted waterways.

In the Sailing Rules of International Regulation for Preventing Collisions at Sea, 1972, any definite distance between two vessels approaching each other is not referred for adequate maneuvering to avoid collision. At sea the officer in charge of bridge duty is required to guess safe distance before he takes maneuvering actions needed to avoid collision. Papers on safe distances calculated on the base of the motiional characteristics of ships for collision avoiding actions are very few. In this paper, the minimum safe approaching distances necessary for actions to be taken to avoid collision are calculated in numerical numbers definitely by mathematic formula based on the maneuvering indices got from experiments of actual ships. On the assumption that two vessels same in size and conditions are approaching each other, the author calculated the minimum safe approaching distance as 4.5 times, sufficient safe approaching one as 9.0 times the length of the ship involved in head-on situation and 5.0 times, 10 times respectively the length of the ship in each case mentioned above in crossing situation.

This paper deals with the design technique of the controller for the discrete system control using Extended Safe Petri Net which is deduced from Petri Net as its subclass with a specific constraint and which is introduced to develop the design and analysis for the discrete systems. First, we propose a construction matrix suitable for the discrete systems that represent the marking flows which are the dynamic behavior of the discrete systems. Next, we develop a method that can design the controller for the discrete system control by analyzing the proposed construction matrix into the incidence matrix of Extended Safe Petri Net. Finally, the validity of the proposed method is shown by using the incidence matrix and matrix equation of Extended Safe Petri Net model.

본 논문은 Vehicular Ad-hoc Network(VANET)환경에서 V2V간의 신뢰적 통신을 지원하기 위해 Safe-Tunneling Zone을 제안한다. 기존의 무선 환경에서는 신뢰적인 경로산출을 위해 ARAN에서 제안된 hop-by-hop 인증을 사용하여 신뢰성은 충족되나 많은 시간과 자원을 소비하는 단점이 있다. 그러나 본 논문에서 제안한 Safe-Tunneling Zone은 송 수신 하고자하는 차량이 각각 신뢰적 에이전트를 선택하고, 선택된 에이전트는 서로의 ID, Rn을 바탕으로 생성된 세션키를 교환함으로서 상호간의 인증을 수행한다. 이와 같이 본 논문에서는 Safe-Tunneling Zone을 통해 기존의 신뢰적 경로 산출 기법보다 수행과정 절차의 간소화, 자원소비 감소, 종단 간의 신뢰적 경로를 통한 데이터의 기밀성 또한 제공 가능하도록 한다.
