The purpose of this study was to determine the relationship between self-leadership, psychological empowerment and job satisfaction in dental hygienists, who form major manpower directly affecting dental care service, and to develop a plan for good-quality intra-organizational personal improvement. To collect data, convenience sampling was performed from May 1 to June 10, 2017 among clinical dental hygienists working at dental hospitals and clinics in Chungcheong and Jeolla Provinces and a self-administered questionnaire was used. Self-leadership was positively correlated with psychological empowerment and job satisfaction; psychological empowerment was positively correlated with job satisfaction. The factors for job satisfaction included psychological empowerment, dental system and self-conformity, and self-leadership. It has been confirmed that there is correlation among self-leadership, psychological empowerment, and job satisfaction in clinical dental hygienists; therefore, it is necessary to use positive psychological empowerment, establish a proactive self-leadership convergence program, and pay attention to the good direction and management of dental organizations with the objective of improving job satisfaction in dental hygienists.

최근의 정보통신 기술의 발달은 의료의 중심을 기존의 진단 및 치료에서 예방으로 이동하게 하였다. 이에 따라 환자 뿐 아니라 건강에 관심이 많은 일반인들이 병원 밖에서도 스스로 건강 증진을 위해 질병 예방을 수행할 수 있도록 지원하는 셀프케어 시스템들이 개발되어지고 있다. 그러나 현재 개발되어지고 있는 셀프케어 시스템들은 대부분 회원 등록의 과정이 필수적이며, 또한 회원 등록 과정에서 자가진단을 위해 성별과 같은 기본적인 정보를 수동적으로 입력해야 하는 번거로움이 있다. 따라서 본 논문에서는 사용자의 음성과 영상을 이용한 성별 인식을 통해 비 등록 사용자에 대한 기본정보를 자동으로 인식하고 온톨로지를 이용한 자가진단 서비스에 적용함으로써 회원 등록을 원치 않는 비 등록 사용자에 대한 편의성을 고려하였다. 또한 온톨로지를 이용한 자가진단 서비스의 진단 결과로 질환에 대한 정의 및 증상, 치료 방법을 설명하고 증상의 경중에 따라 방문 치료할 진료과에 대한 정보를 제공함으로써 사용자가 스스로 건강을 진단하고 진단결과에 따라 간단한 치료를 할 수 있으며, 증상의 악화를 예방할 수 있도록 도와준다.

As coffee's taste and scent are emphasized, and interior atmosphere has changed along with sale of brand's own products, there are also epochal trend changes in interior. So, changes within the space should be focused onto open type self coffee shop, a new cultural space distinguishable from existing coffee shops. Therefore, in this study, the following results could be obtained by performing customer-centered, spatial structural characteristics research on 5 take-out coffee shops opened after 2005 that are practicing self service in Busan and Gyeongsangnam-do regions. In this study, it was shown in the above results that location of the entrance, kitchen, and condiment bar, area per person, size and positioning of furniture, area of windows and doors, etc have strong influences for self service which customers themselves carry their food. Therefore, in planning the interior of self coffee ship in the future, presentation of more effective and practical space based on this analysis will be required.

Spatio-temporal join operators are essential to the management of spatio-temporal data such as moving objects. For example, the join operators are parts of processing to analyze movement of objects and search similar patterns of moving objects. Various studies on spatio-temporal join queries in outdoor space have been done. Recently with advance of indoor positioning techniques, location based services are required in indoor space as well as outdoor space. Nevertheless there is no one about processing of spatio-temporal join query in indoor space. In this paper, we introduce continuous spatio-temporal self-join queries in indoor space and propose a method of processing of the join queries over stream data of moving objects. The continuous spatio-temporal self-join query is to update the joined result set satisfying spatio-temporal predicates continuously. We assume that positions of moving objects are represented by symbols such as a room or corridor. This paper proposes a data structure, called Candidate Pairs Buffer, to filter and maintain massive stream data efficiently and we also investigate performance of proposed method in experimental study.

This research suggested the hygienic spatial composition of sell-service restaurants applying HACCP(Hazard Analysis and Critical Control Point System). The circulation of the food, dishes, waste, workers and customers were each fractionated and arranged according to the hygienic sequence of cooking food in kitchen and process for eating food within the customer space. The spaces were separated by the degree of cleanness(clean area, semi-clean area, contaminated area). After that, hygiene facilities to remove contamination and pass facilities intended to control moving were added at the possible points of cross-contamination in oder to prevent the cross-contamination. For hygienic spatial composition of self-service restaurant, the following should be acknowledged: In the kitchen, spaces in which the food is handled after being heated should be located in the clean area. As of the customer space, spaces where dishes are prepared, food and water is received, and the table hall should be located in the clean area. Food circulation should flow from the contaminated area to the clean area. Food, dishes, waste should be moved through pass facilities so that workers do not have to come and go between other areas of cleanness. Also lockers for private clothes and lockers for uniforms should be separated. Hygiene facilities should be easily accessible so that workers can use them whenever they enter their working area. The contaminated area where dirty dishes are dealed with should be separated from the clean area. Waste should be thrown out without crossing cooking areas. As of customer circulation, the hygiene facility for hand washing should be located near the space where dishes for self-service are placed. The customer circulation should lead customers to leave restaurants after giving back the dirty dishes in the contaminated area.

In recent years, service delivery systems employing a self-service approach have been rapidly spreading. Since a self-service system provides a lower product price, it attracts more customers. However, some system managers are still hesitant to accept a self-service system, because there is no systematic model to predict its performance. Therefore, this research attempts to provide a systematic and quantitative model to predict the performance of a self-service system, focused specifically on a self-service gas station. Under this model, the traditional queuing theory was adopted to describe the general self-service process, but it is also assumed that some changes occur in both the customer arrival rate and the service performance rate. In particular, the price elasticity was introduced to capture the change in the customer arrival rate, and the existence of learning effect and helpers were assumed to design the changed service performance rate. Under these assumptions, a simulation model for a self-service gas station is established, and three performance measurements, such as average number of customers, average waiting time, and Utilization are observed, depending on the changes in price difference and helper-operating time. In this research, the optimal operation strategy for price differentiation and helper-operating time is proposed in accordance with the level of the customer learning rate. Although this research confines the scope of the study to the self-service gas station model, the results of this research can be applied to any type of self-service system.

In this study, we proposed a hierarchy process analysis model for Kiosk known as technology-based self-service, In addition, we deduced the selection factors based on the literature review and calculated the weight of the factors. To estimate the priorities of selection factors, we used the data collected from consumers who have used Kiosks at cafe or fast food restaurant. The results of the study showed that the convenience among the factors in the first stage, consisted of safety, design, convenience, informativity, and responsiveness, revealed the most important factor in both cafe and fast food restaurant. Synthetic calculation of the first stage factors and the second stage factors showed that simple procedure was the most important factor. The results of comparing the priorities between cafe and fast food restaurant showed that consumers assessed their priorities differently in simple procedures, nutritional information, and fast menu provision.

While the introduction of kiosk has become an essential element, enjoying the effect of labor cost reduction, it has not been able to embrace the senior population due to the digital divide. This study investigated which factors have relationships with conflict over use for kiosk from the viewpoint of shadow work that appears during self-service kiosk use. An analysis of 159 seniors through survey revealed that both technostress and subjective norms had significant relationships with conflict over use for kiosk, and that the perception of shadow work had a partial mediating effect on these relationships. Further, user experience showed a moderating effect on the relationship between technostress and perception of shadow work. These results suggest theoretical and practical implications related to digital shadow work, providing the relevant policy regarding digital inclusion for seniors.
