The business card is regarded as the simplest means as well as a tool the most likely to use as a means of sales. Every day, we are exchanging business cards with many customers, but the paper based business card is easy to discard and difficult for searching information on the business card. As a solution, if we take a photographed business card with a smart phone and make it into a database, we can easily obtain customer information we wanted for sales at any time. In this study, we develop an application solution based on electronic business card database that supports sales management. The system operates in a cloud environment and has various decision support functions such as customer's human network management, customer classification, and finding prospective customers.

국내에서는 장기 경기침체로 인해 여성들이 창업시장에 도전하는 경우가 많아지고 있으며, 더 나아가 여성창업자들을 위한 민관중심의 창업지원 프로그램이 창업지원센터를 중심으로 시행중에 있다. 본 연구에서는 이러한 여성창업자들이 창업을 통해 성과를 달성하는데 필요한 여러 가지 요인들이 있는데, 개인적인 역량이나 업무적인 역량외에 여성만의 가지고 있는 특징을 독립변수로 선택하여 여성기업의 창업성과를 검증하고자 한다. 여기에 창업기업들에게 정부가 지원하는 정책적인 요인도 조절효과로 추가하여 여성창업자의 창업성과를 조사하였다. 이를 검증하기 위하여 총 250명을 대상으로 설문조사를 실시하였는데 설문에 참여하여 답한 내용중 일부가 누락되었거나 부정확한 표기를 한 설문을 제외하고 실질적으로 총 212명의 여성창업자들을 대상으로 창업성과에 영향을 미치는 요인들에 대한 설문을 통해 결과치를 분석하였다. 분석결과 첫째, 여성창업자 개인의 특성에 따라 창업성과에 (+) 의 영향을 미치는 것으로 나타났다. 둘째, 여성창업자의 업무적 특성인 독창성, 아이디어, 자원분배역량, 지도역량, 네트워크 구축, 인맥확보등이 여성창업자의 창업성과에 모두 정 (+) 의 영향을 미치는 것으로 나타났다. 셋째, 여성창업자만의 특성인 경력단절 유무와 결혼유무에 대해서는 회귀분석을 통한 나타난 결과는 창업성과와 무관하다는 것으로 나타났다. 넷째, 조절효과인 정부의 창업지원정책은 여성의 창업성과에 유의한 영향을 주는 것으로 나타났으나 그 효과가 여성창업자의 다른 독립변수를 능가할 만한 효과로 나타나지는 않아서 정부의 여성창업자에 대한 정책지원이 좀 더 보강되고 확장되어야만 창업의 성과가 더 높아질 수 있음을 시사한 것이다.

This study considered network quotient (NQ) of deluxe hotel employees and schematized characteristic attributes of being selected by employees with image through correspondence analysis in terms of cognition degree. Self-administrated questionnaires were completed by employees (292 samples) and data were analysed by frequency, t-test, one-way ANOVA, reliability and correspondence analysis. First, the hotel employees indicated the high average value in "participating in special education or seminar for improving ability ($3.85{\pm}0.76$). Second, as a result of analyzing difference according to gender, the average value in men was higher than in women. It was indicated that the higher age and career lead to a rise even in the average value of relationship index. Third, in consequence of carrying out correspondence analysis in order to prepare image map according to cognition level on relationship index in hotel employees, the measurement item that is placed in the closest distance to the response as saying of not so very was the response as saying of "having a lunch (dinner) engagement twice or three times a week." On the other hand, the response as saying of "tending to have many acquaintances compared to coworkers" was schematized in the close distance to the response as saying of very so.

소셜 네트워크가 발전함에 따라 인맥형성과 정보공유 의 목적뿐만 아니라 마케팅, 추천 등 여러 분야에 활용됨에 따라 정보를 단시간 내에 더 많은 사용자들이 공유하기 위해 영향력이 높은 사용자를 필요로 하고 이를 위해 정확한 사용자 영향력 판별이 요구된다. 그러나 누구나 정보를 공유할 수 있고 그 양이 너무 방대하기 때문에 신뢰성 없는 정보를 공유하는 문제가 발생한다. 이에 본 논문에서는 소셜 네트워크에서 신뢰성을 고려한 사용자 영향력 판별 기법을 제안한다. 제안하는 기법에서는 신뢰성에 의한 네트워크 간소화와 사용자의 직-간접적인 영향력을 고려하여 영향력을 판별함으로써 정확성을 향상시킨다.

From October 1993 to February 1996, 9 patients with Wolfr-Parkinson-White syndrome underwent surgical ablation of the accessory atrioventricular conduction pathways. The indications for surgical ablation we e radiofrequency ablation failure in 6 cases, multiple accessory pathways in 1 case, catheter tip fracture ducting catheter ablation in 1 case and additional procedure(redo mitral valve replacement due to valve thrombosis) in 1 case. There was no operative mortality. The postoperative complications were noted In 2 cases pericardial effusion and wound Infection. All patients had accessory atrioventricular connections ablated which were proven by surface ECG and follow-up electrophysiologic study and have remained free of symptomatic tachycardia. The indications for surgical treatment of Wolff-Parkinson-White syndrome are radiofrequency ablation failure, multiple pathways, or when additional procedures are required The present results were satisfactory.

SNS is a social networking service that helps people to have a two-way communication, manage their personal relationships and share information. The domestic and international SNS markets have attained a steady growth, and their growth is being more accelerated recently. Under these circumstances, immature students are more likely to show negative cyber behavior. This study attempted to analyze the relationship between the use of SNS, motives of SNS use, the use of active SNS functions, SNS-dependency and views in SNS and negative SNS behaviors among elementary and middle school students. For this, negative cycber behaviors are classified into four stages depending on the severity, for each of which distribution of factors is investigated and the combination of factors to determine each stage is obtained through association rule analysis. As a result, it is found that 85% of the students rarely show negative cyber behaviors, stealing personal information and contacting with strangers are the most frequent negative behaviors, and students with a great dependency on SNS are highly probable to show negative behaviors.

We in this paper propose a social network based on ontology in Korea Institute of Oriental Medicine (KIOM). By using the social network, researchers can find collaborators and share research results with others. For this purpose, first, personal profiles, scholarships, careers, licenses, academic activities, research results, and personal connections for all of researchers in KIOM are collected. After relationship and hierarchy among ontology classes and attributes of classes are defined through analyzing the collected information, a social network ontology are constructed using FOAF and OWL. This ontology can be easily interconnected with other social network by FOAF and provide the reasoning based on OWL ontology.
