박선민 한국피부과학연구원 2013 대한피부미용학회지 Vol.11 No.2
This study is analyzed to collect data for 472 female college students attending University in Seoul. According to the Transtheoretical model, Divided into 5 groups of female college students, we compared and analyzed the consumer response of cosmetics 4P, such as cosmetic purchase characteristics, cosmetics products, prices, advertising, point of purchase and so on. According to the results of this study, conclusions and discussion are as follows. First, the result of investigation of the use of cosmetics on the makeup of Female University Students, Using of the Color cosmetics intend to increase according to high monthly income, pin money and unmarried woman. Second, in all groups, the places of cosmetic purchase were intend to increased department store, cosmetic brand shop, and cosmetics supply. Third, in all groups, the preference in the selection of color cosmetics were high of BBcream and foundation. In addition, on the basic cosmetics selection, cleanser and toner/lotion items had high purchasing preferences. Fourth, in the color cosmetics using group, satisfaction of cosmetics were high. Fifth, in the group of preparations on color cosmetics had more impulsive cosmetic buying tendency. Finally, high income and pin money lead the purchase of cosmetics in department stores. On the other hand, the purchase of brand shops and cosmetics shops were increased in the lower income levels, and a pin money.

The vulnerability of ocean should be assessed to establish the climate change adaptation policy in field of the ocean, which has big effect on human and natural system. In this study, the criteria for assessing vulnerability of ocean to climate change were employed in terms of sensitivity, adaptative capacity and exposure. And suitable indicators for the criteria were selected and spatial data set for the indicators was prepared. In the ocean sector, the data for indicators were divided into two types, such as the inland and ocean data. The inland data were extrapolated and integrated to the coordinate of ocean data for the vulnerability assessment to climate change. As a result, the spatially diverse distribution of vulnerability on the ocean could be derived from the integration of two types of data. The results showed that southwestern ocean is much more sensitive than west and east ocean. Also southwestern ocean of exposure ratio of change is higher than the other part of ocean. On the other hand the adaptative capacity found that the highest in east ocean. The vulnerability assessment result showed southwestern ocean is more vulnerable than the other part of ocean. 자연 및 인간 시스템에 큰 영향을 주고 있는 해양 부문의 기후변화 적응 대책 수립을 위해서는 기본적으로 해양에 대한 기후변화 취약성 평가가 이루어져야 한다. 본 연구에서는 해양 부문의 취약성 평가를 위해 민감성, 적응성, 노출 등의 규준을 설정하고, 각 규준에 적합한 평가지표를 선정 후 지표별 공간자료를 구축하였다. 해양부문에서는 평가지표 자료가 육지영역과 해양영역으로 구분되어 있었으나, 본 연구에서는 행정구역별 육지영역 자료를 해양 영역으로 외삽을 통해 통합하였다. 그 결과, 해양부문의 취약성을 해양영역에서 공간별로 다양하게 나타낼 수 있었다. 민감성의 경우, 남서쪽 해역이 동해와 서해에 비하여 월등히 높은 값이 나타났고, 노출의 경우 서해와 서・남해 해역이 변화율이 높게 나타났다. 반면 적응성의 경우, 동해가 적응성이 가장 높게 나타났으며 전라남도와 제주도 북쪽 해역 또한 다른 행정구역에 비하여 적응성이 높게 나타났다. 이 세 가지 규준을 통하여 평가한 결과 상대적으로 적응성이 높지만 노출과 민감성은 월등히 높은 값을 나타낸 남서쪽 해역이 두드러지게 취약성이 높게 평가되었다. 하지만 본 연구에서 진행된 해양 부문의 취약성 평가는 제한적인 지표를 사용하였기 때문에 적절한 취약성 평가에 필요한 지표들의 자료구축이 필요하다.

Purpose : Cephalhematomas rarely lead to serious complications, such as skull fractures and intracranial hematomas, so CT and/or MRI scans are indicated only in cases in which depressed fractures are suspected or neurologic symptoms develop. Nevertheless, we have experienced several cases of cephalhematomas associated with intracranial hematomas in the absence of remarkable neurologic symptoms. The aim of this study was to evaluate the correlation between cephalhematomas and intracranial hematomas and determine the need for neuroimaging in infants with cephalhematomas. Methods : Infants who were admitted to the NICU with cephalhematomas and underwent neuroimaging (CT and/or MRI) between January 2002 and July 2006 were evaluated. Neuroimaging was done when the symptoms suggested the development of an intracranial hematoma. Results : Among 54 infants with cephalhematomas, 18 infants underwent neuroimaging. Six of 18 infants (33.3%) had intracranial hematomas, 4 infants had epidural hematomas, and 2 infants had subdural hematomas. Four of these 6 infants had neurologic symptoms or depressed skull fractures; 2 infants had no neurologic symptoms or depressed skull fractures. The neuroimaging was done to evaluate the cause of an excessive elevation of serum bilirubin and unexplained anemia. There were no remarkable differences between the infants with and without intracranial hematomas with respect to gestational age, birth weight, head circumference, diameter of the cephalhematoma, neurologic symptoms, and other clinical signs and symptoms. Conclusion : Based on this study, intracranial hematomas are common complications of cephalhematomas, thus more careful inspection and neuroimaging may be needed in cases of cephalhematomas in newborns.
고온유변특성 분석을 통한 세라믹 섬유 용융 방사 제조 조건에 대한 탐색

세라믹섬유는 넓은 비표면과 높은 비강도 특성 때문에 촉매 담체, 필터, 단열재, 융복합 소재 등으로 널리 사용된다. 본 연구에서는 슬래그 재생원료를 활용한 섬유화 공정에서 슬래그 종류별 조성별 용융 레올로지에 대한 분석을 진행하였다. 조성별 용융물의 고온 점도는 균질한 용융조성물을 고온으로 용융한 후에 냉각하며 온도에 따른 점도를 회전식으로 측정하고, 경화되어 토크가 많이 걸리는 온도에서는 오실레이션 모드로 측정하여 loss modulus와 storage modulus로부터 계산되는 complex viscosity를 구하는 방법으로 연화점 근처까지의 온도범위까지 점도변화 그래프를 얻고 배합비에 따른 용융조성물의 점도를 비교하였다. 연화점 및 용융점 등을 TGA/DTA를 사용하여 분석하고, 조성별 유변특성 분석을 통해 섬유화에 적합한 조성 및 섬유화 조건을 탐색하였다.
