  • This study aimed at developing a down jacket prototype that utilized sunlight as an alternative energy source with no air pollution. The jacket is filled with flexible solar panels and has a heat-generating function and LED function. In this study, three smart down jacket prototypes were developed, and the jacket's capabilities were demonstrated through the thermal effect on the performance test. The typical output voltage of the flexible solar panels was 6.4V. By connecting the 2 solar cell modules in series, the final output voltage was 12.8V. A battery charge regulator module was used the KA 7809 (TO-220) of 9V. Three heating pads were to be inserted into the belly of the jacket as direct thermal heating elements, and the LED module was configured, separated by a flash and an indicator. The smart down jacket was designed to prevent damage to the down pack without the individual devices' interfering with the human body's motion. Because this study provides insulation from extreme cold with a purpose, the jacket was tested for heat insulation properties of non-heating, heating on the back, heating on the abdomen, and heating on both the back and abdomen in a sitting posture in a static state. Thermal property analysis results from examining the average skin temperature, core temperature, and the temperature and humidity within clothing showed, that placing a heating element in one place was more effective than distributing the heating elements in different locations. Heating on the back was the most effective for maintaining optimal skin temperature, core temperature, and humidity, whereas heating on the abdomen was not effective for maintaining optimal skin temperature, core temperature, or humidity within clothing because of the gap between the jacket and the body.

  • 본 논문에서는 멜라닌과 헤모글로빈 등의 피부 색상을 구성하는 주요한 요소들을 카메라의 RGB 신호로부터 직접 계산하는 방법을 제안한다. 피부 색상의 주요한 요소들은 통상적으로 특정한 장비를 이용하여 분광 반사도를 측정하고, 측정된 빛의 일부 파장에서의 값들을 중심으로 재구성하는 방법을 사용한다. 이와 같은 방법으로 산출된 값들은 멜라닌 지수, 홍반 지수와 같은 것들이 있으며, 분광반사도 측정 장치나 다중스펙트럼 카메라 등의 특수한 장비를 필요로 한다. 일반적인 디지털 카메라로부터 이와 같은 성분요소들에 대한 직접적인 계산방법은 찾아보기 어려우며, 독립성분 분석(Independent Component Analysis)을 이용하여 멜라닌과 헤모글로빈의 농도를 간접적으로 계산하는 방법은 제안되어 있다. 이 방법은 일정한 RGB 영상의 영역을 대상으로 하여, 주성분 분석(Principal Component Analysis)과 유사한 방식으로 멜라닌과 헤모글로빈의 특성벡터를 추출하고, 농도를 계산할 수 있다. 이 방법의 단점은 일정한 영역의 화소 그룹을 입력으로 이용하기 때문에 화소단위의 직접적인 계산이 어렵고, 추출된 특성벡터는 최적화 방식으로 구현하기 때문에 실행할 때마다 다른 값으로 계산되는 경향이 있다. 최종적인 계산은 특성벡터 자체를 활용하지 않고, RGB 좌표계로 다시 변환하여 멜라닌과 헤모글로빈의 성분을 나타내는 영상 형태로 결정된다. 이 방법의 단점을 개선하기 위하여 제안하는 방법은 특성벡터를 활용하여 RGB 좌표계가 아닌 특징 공간에서 멜라닌과 헤모글로빈의 성분 값을 계산하는 것과, 일반적인 디지털 카메라를 이용하여 피부색에 해당하는 분광 반사도를 계산하는 방법, 분광 반사도를 이용하여 멜라닌과 옥시헤모글로빈, 디옥시헤모글로빈, 카로티노이드 등의 피부색소를 구성하는 세부 성분들의 계산방법 등이다. 제안한 방법은 분광 반사도 측정 장치나 다중 스펙트럼 카메라 등의 특수한 장비를 필요로 하지 않으며, 기존 방법과는 달리 화소단위의 직접적인 계산이 가능하고, 반복 실행에도 동일한 특성을 얻을 수 있다. 제안한 방법은 기존에 비하여 성능의 안정성을 나타내는 표준편차가 15% 수준으로 낮게 나타나 6배 정도의 안정적인 성능을 가진 것으로 추정된다.

  • Nine trace metals (Zn, Fe, Al, Pb, Mn, Cu, Ni, Cr, and Cd) and Se concentrations were determined in organs and tissues(muscle, bone, kidney, liver and skin) of the striped field mice, Apodemus agrarius collected at Daejeo-dong, Pusan city and the Sorak Mt., Kangwon Province. All the trate elements were detected from all the mice examined. As for the metal concentrations in the mice from Daejeo-dong, Zn, Fe, Al, Mn, Ni and Cr were significantly higher than those in Sorak Mt.(p<0.05), suggesting that pesticides including Zn and factory wastes containing several metals might contaminated the environment of Daejeo-dong. As regards the element concentrations in each organ and tissue, Fe, Al, Pb, Mn, Cu, Cr and Cd concentrations were high in liver or kidney; Zn in skin and bone; Ni in bone, skin and kidney; and Se in muscle, liver and skin in all the mice examined. There were significant differences(p<0.05) between juveniles and adults in average concentration of metals(Zn, Fe, Pb, Mn, Ni, and Cd) in every organs and tissues of mice collected at Daejeo-dong. Much higher average levels of metals in juveniles indicate that considerable burdens fo metals might be transferred through the placenta. However, there were no significant differences between males and females, and between young and old adults in average metal concentrations, which suggests that the mice might accumulate the metals during their life time, although they might excrete the metals not only through reproductive activities, such as parturition, lactation and ejaculation of semen, but also through molting, judging from higher accumulating ratios of most metals in skin of adults than of juveniles.

  • The blinds in the intermediate space are installed to block the direct solar radiation. As the blind divide the airflow of intermediate space into two, thermal performance of Double-Skin Facade (DSF) are affected by the blind position. Therefore blind position should be planed with careful consideration in order to maximize the thermal performance of DSF. In this study, CFD was peformed to analyze the effect of blind position in multistory-type DSF in variation of other DSF elements. The simulation results showed that the case with narrow depth of intermediate space and outlet on upper side of outer-facade, it is profitable to place blind as close as possible to the outer-facade. In the other cases, the blind should maintain 0.15 m distance from outer-facade.

  • Purpose: Carcinosarcomas are rare neoplasms in which both malignant epithelial and mesenchymal elements are identified. We have found only twenty one cases of primary cutaneous carcinosarcoma in the English language literature. Therefore it has been difficult to diagnosis because its unclear etiology and low frequency. Methods: A 31-year-old young man with a protruding mass on his ankle dorsum was examined. The tumor was $7{\times}6{\times}3\;cm$ sized and arose from a burn scar. The mass was wide excised and applied split thickness skin graft. Characteristic pathologic finding was a mixture of squamous cell carcinoma and malignant fibrous histiocytoma. Results: Three months after the operation, the patient died of multiple metastasis to the liver, lung and finally of sepsis despite adjuvant chemotherapy and adjuvant radiotherapy. Conclusion: If a metastatic cutaneous carcinosarcoma is diagnosed, wide excision is required. There should be more aggressive management to minimize the risk of recurrence. Further research into the etiology and pathophysiology of the disease and a more careful differential diagnosis may allow improvement in treatment.
