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.

With the increasing number of skin care shops, service quality development that can meet the customer needs is needed to obtain differentiated competitive advantage. Accordingly this study was attempted to provide basic data on marketing necessary for operating a skin care shop by identifying the impact of service quality on perceived reciprocity and long-term relationship orientation among the customers using a skin care shop. This study conducted a survey of 290 female customers using skin care shops located in Seoul and Gyeonggi province, Jeollanamdo and Jeollabukdo, and Gyeongsangnamdo and Gyeongsangbukdo through personal visit, e-mail, and post service, and the collected data were analyzed with SPSS Ver. 18.0 and Amos Ver. 18.0. As a result, it was proven that overall goodness-of-fit to the theoretical model of the research hypotheses set in this study is good. In Hypothesis 1, "Skin care specialist's work ability, facility and sanitation, and care products had a significant positive (+) impact on perceived reciprocity," which was partially adopted. In Hypothesis 2, "Skin care specialist's work ability, care products, and devices and tools had a significant positive (+) impact on long-term relationship orientation," which was adopted. In Hypothesis 3, "Perceived reciprocity had a significant positive (+) impact on long-term relationship orientation," which was adopted. Therefore, it can be concluded that skin care specialist's work ability, facility and sanitation, care products, and devices and tools are the service quality elements for allowing customers to feel thankful or encouraging them to visit the skin care shops continuously.

In this paper, a method to directly calculate the major elements of skin color such as melanin and hemoglobin from the RGB signal of the camera is proposed. The main elements of skin color typically measure spectral reflectance using specific equipment, and reconfigure the values at some wavelengths of the measured light. The values calculated by this method include such things as melanin index and erythema index, and require special equipment such as a spectral reflectance measuring device or a multi-spectral camera. It is difficult to find a direct calculation method for such component elements from a general digital camera, and a method of indirectly calculating the concentration of melanin and hemoglobin using independent component analysis has been proposed. This method targets a region of a certain RGB image, extracts characteristic vectors of melanin and hemoglobin, and calculates the concentration in a manner similar to that of Principal Component Analysis. The disadvantage of this method is that it is difficult to directly calculate the pixel unit because a group of pixels in a certain area is used as an input, and since the extracted feature vector is implemented by an optimization method, it tends to be calculated with a different value each time it is executed. The final calculation is determined in the form of an image representing the components of melanin and hemoglobin by converting it back to the RGB coordinate system without using the feature vector itself. In order to improve the disadvantages of this method, the proposed method is to calculate the component values of melanin and hemoglobin in a feature space rather than an RGB coordinate system using a feature vector, and calculate the spectral reflectance corresponding to the skin color using a general digital camera. Methods and methods of calculating detailed components constituting skin pigments such as melanin, oxidized hemoglobin, deoxidized hemoglobin, and carotenoid using spectral reflectance. The proposed method does not require special equipment such as a spectral reflectance measuring device or a multi-spectral camera, and unlike the existing method, direct calculation of the pixel unit is possible, and the same characteristics can be obtained even in repeated execution. The standard diviation of density for melanin and hemoglobin of proposed method was 15% compared to conventional and therefore gives 6 times stable.

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.
