인터넷이 일반인들에게 널리 활용되면서 웹 사이트의 수가 기하급수적으로 증가하고 있으며, 각각의 웹 사이트에 저장된 정보의 양도 급속히 증가하고 있다. 따라서, 웹 사이트에서 자신이 보유한 정보를 방문자들이 쉽게 검색할 수 있도록 자체 검색 서비스를 제공해야 하는 필요성이 점차 커지고 있다. 이를 위해, 각 웹 사이트의 정보를 중앙 데이타베이스에 저장하고. 검색 범위를 자신의 사이트에서 제공한 데이타에 제한하여 검색하는 사이트 제한 검색이 널리 사용되고 있다. 본 논문에서는 오디세우스 정보검색용 객체관계형 DBMS 를 사용하여 사이트 제한 검색을 효율적으로 구현하는 두 가지 방법을 제안한다. 다음으로, 본 논문에서 제안한 사이트 제한 검색의 구현 방법은 대용량 데이타베이스에서 사이트 제한 검색을 수행하더라도 검색 속도가 전혀 저하되지 않음을 실험을 통해 입증한다.

딥러닝 기반 성별 및 연령 추정은 현재 다양한 응용분야에 적용하기 위하여 활발히 연구되어 왔다. 최근 몇몇 기업에서는 개인정보 보호의 문제로 성별 추정 서비스를 중단하고 있기는 하나, 사용자 및 관람객의 특성 분석등을 위하여 그 필요성이 계속하여 대두되고 있는 상황이다. 본 논문은 기존에 성별 및 나이 추정을 위한 유료서비스에 대한 특성과 사용 문제점 등을 세분화하여 조사하고 성별 및 연령 추정 기반 기존 연구들의 특성을 분석한다. 추후 이 서비스를 기반으로 전시 · 컨벤션 산업에서의 관심도 분석 및 재방문 의사를 파악하는데 활용하고자 한다.

In this study, eye tracking was used for the appearance of the robot during the social robot design study. During the research, each part of the social robot was designated as AOI (Areas of Interests), and the user's attitude was measured through a design evaluation questionnaire to construct a design research model of the social robot. The data used in this study are Fixation, First Visit, Total Viewed, and Revisits as eye tracking indicators, and AOI (Areas of Interests) was designed with the face, eyes, lips, and body of the social robot. And as design evaluation questionnaire questions, consumer beliefs such as Face-highlighted, Human-like, and Expressive of social robots were collected and as a dependent variable was attitude toward robots. Through this, we tried to discover the mechanism that specifically forms the user's attitude toward the robot, and to discover specific insights that can be referenced when designing the robot.

This study was conducted to provide with baseline data with the purpose of increasing the values of medical services. Self-administered questionnaire survey was conducted on 236 patients at a dental clinic follow-up visit in dentist clinic Gyeongnam area from June 2013 to August 2013. All statistical analyses were performed using SPSS. The motivation visiting the dental clinic is that the first one is introduction from the family and friends, the second is accessibility, the third is conspicuity and the last one is awareness of the dentist. The main variables in the process of treatment are service system, kindness, satisfaction of service, efficient of re-call system. The relief of discomfort at revisit show the highest score in the process of implant treatment and intention of revisit hereafter do in the prostheses process. In the correlation between main variables, service system and relief of discomfort at revisit (r=0.440, p<0.001), kindness and satisfaction of medical service (r=0.675, p<0.001), revisit hereafter and satisfaction of service (r=0.387, p<0.001) and efficiency of re-call system and revisit showed the highest correlation. The influence on satisfaction of dental service show meaningful level in kindness (p<0.001) and efficiency of re-call system (p<0.05). The intention of revisit is affected meaningfully by relief of uncomfort (p<0.05), service system (p<0.05), kindness (p<0.01) and efficiency of re-call system (p<0.01). In summary, the personal network of patients is most important variable at intention for revisit of dental clinic. As satisfaction of kindness and efficiency of re-call system is higher, satisfaction of medical service and intention for revisit are shown higher. Therefore further research for improvement of satisfaction for medical service and of intention of revisit at the dental clinic should be carried out.

Background: The aims of the present study were to assess and compare mid-term clinical outcomes including recurrences between endovenous laser therapy (EVLT) and stripping. Material and Method: Between January 2007 and February 2010, 318 limbs in 237 patients with saphenous truncal varicosities were treated by laser energy using a 980 nm diode or were treated with conventional stripping. At the initial visit and at 1, 2, 6, 12, 18, 24, and 36 months postoperatively, clinical examination and questioning for Venous Clinical Severity Score (VCSS) as well as duplex ultrasonography were done. In order to compare clinical outcomes between the two treatment groups, EVLT versus stripping, all data were processed and analyzed. Result: There were no significant differences between the two treatment groups in the extent of the reflux and the number of insufficient perforating veins. The in EVLT and the stripping group at 12 months were $90.3{\pm}4.5%$ and $93.9{\pm}4.2%$, respectively (p>0.05). Total recurrence rates were 4.4% in the EVLT group and 1.5% in the stripping group (p>0.05). In both groups, the VCSS scores were significantly reduced at week 1, 1 month, and 2 months after EVLT or stripping (p<0.001). Conclusion: Efficiency in eliminating truncal saphenous vein incompetence and reducing venous clinical severity were equal in the two treatment groups.
