The aim of this study was to evaluate the clinical efficacy of mouthrinses prepared by sterilized water-generating $device(Purister^{(R)})$ on the control of gingivitis and incipient periodontitis when it was used as a adjunctives to the mechanical plaque control. 40 healthy patients with gingivitis or incipient periodontitis were divided into two groups. Patients in the experimental group use mouthrinses prepared by sterilized water-generating $device(Purister^{(R)})$ after tooth brushing while patients in the control group do only tooth brushing for plaque control. All patients received scaling and tooth brushing instruction. 1 week after scaling was set as baseline. Probing pocket depth, clinical attachment level, and bleeding on probing were scored at baseline, 4 weeks. Gingival index and plaque index were scored at baseline, 2 weeks, and 4 weeks. The results were as follows: 1. In the experimental group, gingival index, plaque index, probing pocket depth, and clinical attachment level showed statistically significant decrease, but in the control group, significant increase(p<0.05). 2. There was no significant difference between the experimental and the control group in bleeding on probing, but significant decrease in the experimental group and Significant increase in the control group In a time-dependent manner(p <0.05). From these results, it can be concluded that regular use of mouthrinses prepared by sterilized water-generating $device(Purister^{(R)})$ as adjunctives of mechanical plaque control, may be effective to prevent and treat gingivitis and incipient periodontitis.

Purpose : The purpose of this study was to evaluate the diagnostic efficacy of panoramic radiographs for detection of mandibular fractures. Materials and Methods : The sample was comprised of 65 patients (55 fractured, 10 non-fractured) with 92 fracture sites confirmed by multi-detector computed tomography (CT). Panoramic radiographs were evaluated for mandibular fractures by six examiners; two oral & maxillofacial radiologists (observer A&B), two oral & maxillofacial surgeons (observer C&D), and two general dentists (observer E&F). Results : Sensitivity of panoramic radiography for mandibular fractures was 95.7% in observer A&B, 93.5% in observer C&D and 80.4% in observer E&F. The lowest sensitivity was shown in symphyseal/parasymphyseal areas, followed by subcondylar/condylar regions. Conclusion : Panoramic radiography is adequate for detection of mandibular fractures. However, additional multidetector CT is recommended to ascertain some indecisive fractures of symphysis and condyle, and in complicated fractures.

Background: In spite of harmfulness of smoking, the smoking rate of adult is high in Korea. Korea is one of the heavist smoking countries, due to the tolerant environments towards smokers, the weak anti-smoking police and the undeveloped smoking cessation programs. Recently, though those who succeed in stoping smoking and maintaining it are increasing, there are few studies about the characteristics of those who successful in smoking cessation. The purpose of this study is therefore to identify what factors are likely to influence the effectiveness of smoking cessation in adult Korean smokers. Method: Participants were 108 smokers(success group 45, failure group 63), registered at an public health center(80) and working area 28) smoking cessation program from Apr. to Nov. 2006 were included, the questionnaire consisted of questions of health perception(HP), satisfaction(SA), vality(VA), emotional function(EF), fagerstrom tolerance questionnaire, (FTQ) and the why test. Result: There was no relationship between the two groups in the demographic characteristics. In view of success of smoking cessation that can influences them such as physical pain, Nicotine dependence, stress rating pain and counselor of smoking cessation Conclusion: The results of logistic regression analysis was shown that the factor that is most associated with success of smoking cessation is the counselor of smoking cessation. This means that the more people who smoke consult with nurse and the longer the period of utilizing the smoking cessation clinic is, the more successful they are in smoking cessation.

현대 사회의 흐름이 사용자, 참여자 주도형으로 변화하면서 디자인 분야 역시 사용자가 전체 디자인 프로세스에 적극적으로 참여하는 양상을 띠고 있다. 네트워크 기반 환경 구축으로 사용자는 디자인 프로세스 전반에 세부적인 참여가 용이해졌으며 이에 생산자와 사용자 간의 개방적이며 쌍방향적인 프로세스가 요구되고 있다. 그러나 현재까지 소비자 참여를 고려한 개방적인 디자인 프로세스에 대한 연구는 그리 활발하다고 볼 수 없으며 또한 참여의 범주나 형태가 다소 제한적이었다. 이에 본 연구는 문헌연구와 국내외 사례 조사를 통해 네트워크 기반의 참여적 디자인 프로세스를 규명하고 각 프로세스 단계 별 사용자의 참여 유형과 방법을 프레임 별로 나누었으며, 전문가 심층면담을 통한 검증 및 보완으로 소비자가 참여할 수 있는 네트워크 기반의 참여적 디자인 프레임 및 방법을 제안하였다. 참여적 디자인 사례 연구에서는 공공, 서비스, 패션, 제품디자인 사례를 수집, 사용자의 참여 수준에 따른 참여도와 특성을 도출하여 차이점을 분석하였다. 전반적으로 공공디자인 영역은 전 프로세스에 걸쳐 비교적 높은 참여강도를 띄고 있었으며 제품과 패션디자인 영역은 초기 단계인 정보수집 및 의견제시에 참여가 높고 디자인을 구체화하고 실행하는 단계에는 낮은 참여를 보이고 있었다. 사례분석을 통해 참여적 디자인 프레임은 강한 참여단계와 약한 참여단계를 구분되었고, 단계의 강한 참여 유형에 따라 5가지로 나뉘었으며 전문가 인터뷰를 통하여 각 프레임의 프로세스 별로 참여를 강화 시킬 수 있는 방법을 도출하였다. 본 연구의 결과는 쌍방향적 네트워크 환경의 소비자가 참여하는 개방형 프로세스 제시를 통해 디자인 산업전반의 다각화 및 디자인 결과물의 다양성뿐만 아니라 소비자와의 소통을 이끌어 내는데 기여할 수 있을 것이다. The cultural circumstances of user driven society influenced on the design process. The network based society made the user easy to participate to the whole design process, and the users requested an interactive and open design process gradually. However, the previous studies on the design process for participation have been limited and the ranges and types of user participation were limited also. In this study, we clarified the participatory design process through literature reviews and case studies, furthermore, the participatory design framework using the strength level of participation were proposed. The participatory design framework were classified into five types according to the participatory design process and the methods to increase user`s participation were proposed through the expertise interviews. The results of this study can be used as the basis of participatory design study and be applied to the industrial diversification.

본 연구는 poly(ethylene glycol)-poly(ε-caprolactone)-poly(ethylene glycol) (PEG-PCL-PEG) 삼중블록 고분자 계면활성제를 이용하여 제조된 우수한 사용감과 선택적인 클렌징 효과를 갖는 수중유(O/W) 에멀젼 타입의 내수성 자외선 차단 제형에 관한 것이다. 수영, 등산 등 다양한 야외 레저 활동이 많아짐에 따라 내수성 자외선 차단제의 수요가 증가하고 있다. 내수성 자외선 차단제는 물이나 땀에 지워지지 않아야하기 때문에 대부분 유중수(W/O) 에멀젼 제형으로 만들어진다. 하지만, W/O 에멀젼 제형은 오일리한 사용감과 클렌징이 어렵다는 단점이 있다. 이에 비해 O/W 에멀젼 제형은 사용감이 우수하고, 클렌징도 용이하지만, 물과의 재유화가 쉽기 때문에 내수성 특성을 갖는 것이 매우 어렵다. 본 연구에서는 이러한 문제를 해결하기 위해 O/W 에멀젼 제형의 HLB 값(~ 10)을 가지면서도 상대적으로 높은 계면장력을 가짐으로써 재유화에 강한 삼중블록 고분자 계면활성제를 도입하였고, 이를 통해 O/W 에멀젼형 지속내수성 자외선 차단제를 개발하였다. 본 연구를 통해 개발된 자외선 차단제는 우수한 사용감과 지속내수성, 그리고 폼 클렌저와의 선택적인 클렌징 효과를 보여준다. 향후 사용감이 다양화된 새로운 O/W 에멀젼형 자외선 차단제 제품 개발에 도움이 될 것으로 기대된다. This study reports water-resistant oil-in-water (O/W) emulsion-based sunscreening formulations prepared using a poly(ethylene glycol)-poly(ε-caprolactone)-poly(ethylene glycol) (PEG-PCL-PEG) triblock polymeric surfactant. As a result of a variety of outdoor recreational activities such as swimming and hiking, consumer needs for development of advanced water-resistant sunscreen formulations are increasing. Water-resistant sunscreens are mostly based on water-in-oil (W/O) emulsions, because they should not be wiped off by water or sweat. However, the W/O emulsion formulations have a disadvantage in that the feeling of use is oily and difficult to remove. On the other hand, the O/W emulsion formulations are excellent in achieving the better skin feel as well as the easier removal. However, it is difficult to provide the O/W emulsion formulations with the water-repelling performance, since re-emulsification likely occurs upon getting touch with water. To solve this problem, this study proposes a O/W emulsion-based sunscreen formulation, a triblock polymeric surfactant having relatively high interfacial tension HLB value (~ 10). This allows the sunscreen formulations to exhibit the improved water repellence function by preventing their re-emulsification. The sunscreen formation system prepared in this study would be useful for diversification of functional sunscreen products, taking advantages of its excellent emulsion stability, UV protection performance, long lasting water-resistant function and selective cleansing effect with only foam cleanser.
