An aging population and increasing consumer demand for high-quality and innovative new products are key drivers for growth in the cosmeceutical industry. Cosmeceuticals are defined as products with biologically active ingredients that have a measurable effect on the user. This study explored the effects of shopping orientation and store attributes on impulse buying behavior for cosmeceuticals. We obtained 437 usable questionnaires from university students who had purchased cosmeceutical products. Data analysis was conducted using confirmatory factor analysis and structural equation modeling analysis via AMOS 18.0. The findings were: 1) hedonic shopping orientation and convenience shopping orientation had positive effects on product efficacy and promotion of the cosmeceutical store 2) brand shopping orientation had a positive effects on store atmospheric, skin care service, and brand of the cosmeceuticals store and 3) product efficacy and promotion of store attributes had a direct effect on impulse buying behavior for cosmeceuticals. Consumers who tended to enjoy the shopping to refresh themselves and to experience convenient shopping were likely to purchase cosmeceuticals impulsively, which mediated by the store attributes (product efficacy and promotion). Therefore, we confirmed partly causal relationships among the shopping orientation, store attributes, and impulse buying behavior of cosmeceuticals. Both managerial and theoretical implication for practitioners and researchers were discussed for managing product information more efficiently along with promotion strategies to trigger cosmeceuticals consumers in the context of shopping.

This research is written for offering an approach to activate the stagnated industry of the tourist farm through analysis of the current operational problems and situation on some existing tourist farm nominated as such by the authority. There will be some considerations from three different categories : local autonomous groups, tourist farm associations and farm owners. On the other hand, it is assumed that this research can also be utilized as a basic material for activating the tourist farms in the suburban area of Taegu City. The operational problems in the suburban area of Taegu City are as follows : lack of a specialized Product development, the farm operation fund, lack of operational or management ability, lack of public information, etc. There are other Problems regarding law, institution and supporting : complexity of the current system involving all kinds of permission, shortage of financial and taxation supporting, lack of training an expert manpower, lack of ability and cooperation of a deskclerk in charge, etc. Here are some suggestions taking into consideration a respective sector of local autonomous group, tourist farm associations and farm owners for activating the tourist farms in the suburban area of Taegu City. First, a mental turnabout toward a tourist farm is needed from local autonomous groups. The law and institutional base should be arranged while the financial and taxation support is materialized. Second, tourist farm associations should amend or reinforce the existing institution to refresh the current recognition toward the tourist farm through many publicity activities. On the other hand, they should develop the overall tourist farm industry into a better service industry of the rural community by keeping an active system of cooperation with other related groups. Finally, It is advised that they should conceive farms and facilities which can symbolize the tourist farm from the stage of the first construction. In addition to a four-season souvenir development, an effective publicity activity and rational investment management. Above all, they should train themselves in terms of a service spirit before they see the prosperity of the tourist farm community.

This study explored the status of free time activities among the dental technicians who are working at Seoul, Gyonggido, and Gangwondo. On the basis of this research, we aim to present needs and applicable solutions to improve the working conditions and enhance the quality of life through more effective time management in free time activities that lead to their self development and far more enriched life. 500 subjects were randomly chosen and the questionary sheets were provided. Among them, 305 sheets were returned to be analysed through SPSS Win 10.0 software and the results are as follows; First, mean in the satisfaction of leisure activities was 3.44(SD=.73). Mean in sub categories was as follows; psychological factor(M=3.65, SD=.71), social factor(M=3.54, SD=.75), rest factors(M=3.52, SD=.63), physical factor(M=3.43, SD=.88), other factors(M=3.40, SD=.66), circumstantial factor(M=3.33, SD=.63), educational factor(M=3.24, SD=.73). Second, the most relevant sub categories in the satisfaction of leisure activities were social, educational, physical, and other circumstantial factors by sequence. Factors that affect leisure activities satisfaction were career and status of health, which shows statistical significance(p<.001). That is to say, contention of this study is that the general characteristics are closely related with and affect the types and the level of satisfaction in leisure activities of the subjects. Considering these results, the dental businesses and the associations of dental technicians should recognize the needs to improve the time management through more efficient cooperations between dentists and back office dental team, systemized working time, and introduction of incentive system among others. On the basis of this appreciation, the dental business should provide more time and various opportunities with the dental technicians. Dental technicians also need to reconsider their appreciations of leisure activities, that is, leisure activities are not just spending time doing something but they refresh them and enable them to be more active and faithful to home and work.

고유전 커패시터의 유전완화 특성은 시간영역에서 나타나는 커패시터의 동적특성으로 이해될 수 있으며 이것은 DRAM의 재충전 시간동안 충전된 전하를 잃어버리는 가장 주된 요인으로 인식된다. 그러므로 DRAM 동작에 미치는 영향을 고려하기 위하여 고유전 커패시터의 유전완화에 대한 등가회로를 만드는 것이 필수적이다. 그러나 아직까지 등가회로를 만들 수 있는 일반적이고 이론적인 방법이 제시되지 않고 있다. 근 본 연구에서는 고유전 커패시터의 등가회로를 주파수 영역에서 모델링하는 새로운 방법을 개발하였다. 이 방법은 이론적인 체계를 갖춘 일반적인 방법이다. 또한, 본 연구에서는 실험과정을 통해서 이 방법의 타당성으로 확인하였고, 궁극적으로 새로운 방법으로 얻어진 등가회로를 활용하여 유전완화가 DRAM 동작에 미치는 영향을 고찰하였다.

Navigation system is applied in variety of fields including the simple location positioning, autopilot navigation of unmanned robot tractor, autonomous guidance systems for agricultural vehicles, construction of large field works that require high precision and map making process. Particularly utilization of GPS (Global Positioning System) is very common in the present navigation system. This study introduces a navigation system for autonomous field robot that travels to the pre-input path using GPS information. Performance of the GPS- based navigation is highly depended on its receiving rate because GPS receivers do not acquire any navigation information in the period between the refresh intervals. So this study presents an algorithm that improves an accuracy of the navigation by estimation the positional information during the blind period of a low rate GPS receiver. In fact the algorithm calculated the robot's heading in a 50 Hz rate, so the blind period of an 1 Hz GPS receiver is extensively covered. Consequently implementation of the algorithm to the GPS based navigation showed an improvement in guidance accuracy. The conventional field robot directly carried an expensive control computer and sensors onboard, therefore the miniaturization and weight reduction of the robot was limited. In this paper, the field robot carried only communication equipments such as GPS module, normal RC receiver, and bluetooth modem. This enabled the field robot to be built in an economic cost and miniature size.

IEEE 802.11 무선 랜이 보안 측면에서 몇 가지 심각한 약점을 가진다는 것이 알려진 후 이러한 무선 랜 보안의 결함을 줄이기 위하여 많은 연구가 수행되어졌다. 그 중 IEEE 802,lli는 새 무선 랜제품과 함께 새로운 보안 플랫폼을 필요로 하는 궁극적인 장기 해결책이다. 그러나 이 방법은 큰 비용이 들기 때문에 비용이 중요한 작은 기관에게는 적합하지 않을 수 있다. 본 논문은 기존 제품을 조금 변경함으로써 그대로 사용 가능한 무선 랜을 위한 간소화된 키 관리 기법으로 FR-WEP을 제안한다. FR-WEP은 최근 제안된 간소화된 키 관리 기법인 WEP'(9)의 확장으로, 호스트 키와 사용자 키를 모두 사용하는 간소화된 상호 인증과 빠른 재 인증을 통해 인증된 사용자들에게 균일한 키 갱신을 제공함으로써 WEP'의 약점을 보완한다. FR-WEP은 특히, 더 나은 보안을 원하는 작은 기관들에게 무선 랜 보안을 위한 무거운표준안에 대해 좋은 대안이 될 것이다.

예로부터 "갈증이 나면 물을 마셔 해소하고, 번뇌와 근심걱정은 술을 마셔 지워버리고, 피로회복과 정신을 맑게 하려면 차를 마신다"라고 하였다. 이처럼 차는 물과 술보다 오래 마실수록 몸과 마음에 아주 좋은 대자연이 준 귀한 진다(眞茶)이며, 사계절의 기후변화 특징에 따른 양생차를 마심으로써 건강을 유지하게 해준다. 이처럼 차에는 고대인들의 철학사상인 음양의 이치가 숨겨져 있기에 어떤 차를 어떻게 우려 마셔야 음양의 조화를 이루어 양생에 도움이 되는지를 옛 선인들은 알고 있었다. 차의 성분변화에 영향 주는 인자는 천지인의 복합적인 상호작용이 중요하며 그 중에서 차를 다루는 사람의 마음정신이 가장 중요하다. 차는 인간과 자연을 이어주는 교량역활의 천연 양생음료이다.
