본 연구는 판교 테크노벨리를 대상으로 결속형 및 교량형 사회적 자본이 산업단지 내 기술적 혁신성과에 미치는 영향을 고찰하였다. 특히 본 연구에서는 사회적 자본의 선행요인으로 “정보기술 활용”의 역할에 주목하였다. 정보기술을 활용함으로써 내․외부 구성원과의 커뮤니케이션 및 정보교환이 활성화되고 이에 다양한 관계망을 확장시켜 네트워크화 할 수 있기 때문이다. 연구결과 정보기술 활용은 결속형 자본과 교량형 자본에 모두 긍정적 영향을 미치는 것으로 검증되었다. 하지만 사회적 자본이 기술적 혁신성과에 미치는 영향에 있어서는 뚜렷한 차이가 발견되었다. 판교 테크노 벨리의 경우 신뢰나 협력을 중심으로 한 강한 결속 관계보다는 다양한 네트워크를 통해 형성되는 교량형 자본의 효과가 기술적 혁신 성과에 유의하게 작용하고 있음을 알 수 있었다. 이러한 현상은 판교 테크노벨리의 구조적 특성상 IT기반의 기업들이 대부분 입주되어 있으며 비교적 쉽게 정보를 공유하며 다양한 사람들과 자연스럽게 네트워크가 형성되는 특성에 기인한다고 해석된다.

Introduction Clinical laser settings have traditionally been calibrated on abdominal skin to predict and anticipate patterns of injuries in facial skin. This experimental approach has limitations as facial skin and abdominal skin have differences that may influence the depth of laser injury. Objective The primary objective of this study is to analyze the acute pattern of laser injury in abdominal skin and facial skin samples from the same subject and detail the anatomical and biophysical properties that can influence the laser tissue interaction. The secondary objective is to develop a conversion factor that will allow the prediction laser column depths in facial skin based upon laser column depths in abdominal skin. Methods Fifteen healthy subjects were consented and screened. Two 2 mm spots on the face and abdomen were identified and measured and treated with a fractional CO2 laser (Lumenis Ltd, Yokneum, Israel), with an energy setting of 15 mj, 300 Hz at a density of 10. Treatment areas were biopsied and analyzed histologically using hematoxylin and eosin and TUNEL staining. Results Facial skin and abdominal skin have several significant anatomical and biophysical differences (concentration of pilosebaceous units, sebum concentration, and moisture content). Facial tissue demonstrated divergence of laser energy around pilosebaceous units and lateral spread of laser energy along blood vessels. These differences cause attenuation (28%) of the laser energy and result in column depths that are significantly (P

The secondary objective is to develop a conversion factor that will allow the prediction laser column depths in facial skin based upon laser column depths in abdominal skin.Fifteen healthy subjects were consented and screened. Two 2 mm spots on the face and abdomen were identified and measured and treated with a fractional CO(2) laser (Lumenis Ltd, Yokneum, Israel), with an energy setting of 15 mj, 300 Hz at a density of 10. Treatment areas were biopsied and analyzed histologically using hematoxylin and eosin and TUNEL staining.Facial skin and abdominal skin have several significant anatomical and biophysical differences (concentration of pilosebaceous units, sebum concentration, and moisture content). Facial tissue demonstrated divergence of laser energy around pilosebaceous units and lateral spread of laser energy along blood vessels. These differences cause attenuation (28%) of the laser energy and result in column depths that are significantly (P 0.003) shorter in facial tissues (mean depth 415 µm) in comparison to abdominal tissues (mean depth 582 µm).The variations in anatomic, biophysical, and biomechanical properties in facial skin cause an attenuation of the laser column depths in facial skin when compared to abdominal skin. A correction factor of 28% is required to predict the depth of laser columns in facial skin based on laser column depths observed in abdominal skin.
