본 논문은 소셜미디어 마케팅을 분석하고 효과적으로 수행하기 위해서 소셜미디어 마케팅을 4가지 형태로 모델로 구조화한 연구이다. 본 연구에서는 소셜미디어 마케팅의 4가지 유형에 대한 사례를 살펴보고 유형별로 마케팅 효과를 측정하기 위해서 페이스북의 인사이트에서 사용하고 있는 도달(reach)과 참여하는 사람(people engaged)을 결합한 평가방법을 제안하였다. This paper is a study of social media marketing as a structured four types of model in order to analyze and perform social media marketing effectively. In this paper we analyze cases of each types of social media marketing and suggest a new social media marketing evaluation methods by a combination of reach and people engaged in using facebook insight.

This paper presents the prediction of shear strength of oil contaminated clay using fall cone test used to determine the liquid limit of soil. The penetration depth of fall cone is related to water content of soil. Laboratory vane shear can also be related to water content. To explore the relative correlation between penetration depth of fall cone and laboratory vane shear, both fall cone tests and laboratory vane shear test were carried out with water contents of soil. The developed empirical relationships in this studys showed that the shear strength is reduced to 3.9% with 1% increase of oil content. And, the lesser initial water content of contaminated clay, the more shear strength of contaminated clay is affected by oil content.

Objectives : The aim of this study was to evaluate the effects of a composite of bone substitute and collagen barrier membrane (bone patch) for local ridge augmentation at peri-implant dehiscence defects on the clinical efficacy and positional stability in dogs. Materials and methods : Implant placement and ridge augmentation procedure were performed at surgically created periimplant dehiscence defects in canine mandible (n=6). Four treatment modalities were randomly applied: i) bone patch group, ii) Guided bone regeneration (GBR) without pin fixation group (bone graft and collagen membrane), iii) GBR with pin fixation group, and iv) negative control group. After 12 weeks, clinical, micro-CT and histological analyses were performed. Results : Histologic analysis showed that bone patch group had similar results to GBR group and GBR with fixation group in terms of new bone formation. Micro-CT analysis revealed similar results to histologic analysis in terms of total volume maintenance. Operating time was shorter in bone patch group compared to GBR group and GBR with fixation groups. Conclusions : GBR using bone patch could simplify the ridge augmentation procedure with reduced operating time and equivalent biological performance compared to the conventional procedure.
