Background : Many doctors are under a bias toward clinical severity in patients with atopic dermatitis. But the various studios show that atopic dermatitis may produce a range of impacts on the qualify of lift . Nevertheless there is much to be desired about the association between the quality of lift and atopic dermatitis in the department of Dermatology in Korean medicine. Objective : This study was conducted to investigate the impact of the atopic dermatitis on quality of life and explore prognostic factors that influence outcomes. Methods : 70 patients were recruited in this study rho write out more than 90% of Skindex-29 questionnaires. The function of total scores and three domain scores and SCORAD index was investigated and the correlation of each domain scores also . Result : The total scores, showed significant correlation with three domain scores in atopic dermatitis. The correlation of each three domain scores were significant. SCORAD index showed significant correlation with three domain scores and total scores. Conclusion : In this study atopic dermatitis efface of the quality of life in physical, social, and psychological factors. So we considered to the quality of life as well as clinical severity in patient with atopic dermatitis.

Obstacle detection is much studied by using sensors such as laser, vision, radar and ultrasonic in path planning for UGV(Unmanned Ground Vehicle), but not much reported about its characterization. In this paper not only an obstacle classification method using 2-dimensional LMS(Laser Measurement System) but also a decision making method whether to avoid or traverse the obstacle is proposed. The basic idea of decision making is to classify the characteristics by 2D laser scanned data and intensity data. Roughness features are obtained by range data using a simple linear regression model. The standard deviations of roughness and intensity data are used as measures for decision making by comparing with those of reference data. The obstacle classification and decision making for the UGV can facilitate a short path to the target position and the survivability of the robot.

Coprostanol is a metabolic product of cholesterol, formed by microbial action in the mammalian gut. This chemical compound is the major sterol in human and has been routinely studied as a biomarker of sewage pollution in marine and lacustrinesediments. This has led to the search for coprostanol as a biomarker in archaeologicalsoils, in order to detect the presence of fecal material. In this study, five samples of archaeological soils excavated at Wanggung ri, Iksancity, were used to assess the possibility of using coprostanol as indicators of ancient human activity in archaeological areas. The sampled soils were analyzed MXRD,EDXRF for their physical and chemical properties. And coprostanol was analysed byGC/MSD, using SIM method to detect and quantify specific compound. The results showed the soils were composed of quartz and feldspars, inorganicelement such as $SiO_2$, $Al_2O_3$, $Fe_2O_3$ etc. Moreover, the result from the analysis wasindicated that the specific compound is coprostanol. The coprostanol was determined at $0.16~1.01\mug$/g in the range of concentrations. This finding indicate that clear promise exists for the exploitation of coprostanol as biomarker of ancient human activity inarchaeological survey. Therefore such studies can serve to increase the confidence we place on biomarker-based methodologies for assessing fecal pollution. The application of this methodology has proved a simple and effective way of searching for that pattern in successively more aged deposits either known or suspected to contain fecal material. And the more scientific analysis of the soils will be showed to utility of the area ancient dietary life style, ancient environment.

Objectives : The prevalence of allergic rhinitis (AR) is 10-40% worldwide and there are many demands for Traditionl Medicine (TM) treatment for AR. Pattern identification (PI) is essential process in diagnosis and treatment of TM, however, objective assessment measurement for PI of AR in TM is lacked. Methods : PI questionnaire for AR was developed in 2008 by specialists in the department of Otolaryngology of TM, based on systemic and nasal symptoms and signs. However, that questionnaire had many problems in application to clinical practice and has since been revised based on several studies and delphi method. Consequently, the PI questionnaire for AR version 3.0 has been developed. Results & Conclusions : This questionnaire classifies patients with AR as possessing lung-heat, lung-cold, or spleen qi deficiency based on nasal symptoms and general conditions of AR patients. This is first questionnaire for pattern identification of AR. We plan to conduct a validation and reliability study, and revise the questionnaire based on the results of this study.

친환경 천연 소재에 대한 필요성이 증가하면서, 천연 염료에 대한 연구에도 많은 관심이 증가하고 있다. 자연에서 얻을 수 있는 천연 염료 중 하나인 커큐민(Curcumin)은 인체 무독성의 친환경 분자로, 강황에서 발견되는 원료 중 하나이다. 본 연구에서는 커큐민을 잉크화 한 후 잉크젯 프린팅(Inkjet Printing) 방법을 통해 종이와 면직물에 프린트하여 암모니아 및 염화 수소 가스에 대한 색채 감지 거동 특성을 분석하였고, 이를 이용하여 음식물 부패여부를 확인할 수 있는 비색 센서로 제안하였다. 이를 위해 종이와 면직물에 프린트된 시료의 암모니아 가스 노출에 따른 색차를 비교하고, 가역성과 내수성을 확인하였다. 두 시료 모두 암모니아와 염화 수소에 대한 가역반응을 보였으며, 부패한 음식에서 발생하는 미량의 암모니아에 대해서도 육안으로 관찰할 수 있을 정도의 색상 변화를 나타내어, 식품 부패 비색 센서로 활용 가능함을 확인하였다. Increasing the needs for eco-friendly natural materials, much attention on natural dyes has been attracted. Curcumin, one of abundant natural dyes available in nature, is an eco-friendly molecule found in turmeric. In this study, the colorimetric sensing behavior characteristics of ammonia and hydrogen chloride gases was analyzed using curcumin ink-printed paper and cotton fabric by inkjet printing method. The fabricated paper and fabric were utilized as a colorimetric sensor that can track food spoilage. The color changes of the samples printed on the paper and cotton upon exposure to the toxic gases, the reversibility of the color changes, and the water resistance were investigated. Both samples showed reversible reactions with NH3 and HCl, and small amount of ammonia produced by food spoilage was successfully sensed with naked eyes, confirming its capability to warn food spoilage in our daily life.

The hybrid structured photo-electrode for dye-sensitized solar cells was fabricated based on the composites of $TiO_2$ nanoparticles and nanowires. Three samples with different hybrid structures were prepared with 17 vol%, 43 vol%, and 100 vol% nanowires. The energy conversion efficiency was enhanced from 5.54% for pure nanoparticle cells to 6.01% for the hybrid structure with 17 vol% nanowires. For the hybrid structured layers with high nanowires concentration (43 vol% and 100 vol%), the efficiency decreased with the nanowire concentration, because of the decrease of specific surface area, and of thus decreased current density. The random orientations of $TiO_2$ nanowires can be preserved by the doctor blade process, resulted in the enhanced efficiency. The hybrid structured $TiO_2$ layer can possess the advantages of the high surface area of nanoparticles and the rapid electron transport rate and the light scattering effect of nanowires.

This study investigated the effects of the planting season on shoot emergence and the enlargement of bulblets via three propagation methods in Korean native lilies belonging to the Sinomartagon section. One-year-old bulblets of Lilium amabile, L. cernuum, L. lancifolium, and L. leichtlinii var. maximowiczii were obtained through tissue culture, scaling, and seed propagation steps. They were divided into two groups based on the species and propagation method and planted in an open field either immediately in autumn or in spring after wet cold storage. Overall, spring planting increased the shoot emergence rate, delayed the shoot emergence date, and increased bulb fresh weight (BFW) and the bulb enlargement rate (BER) at harvest compared to autumn planting. In terms of the propagation method used to obtain bulblets, BERs were higher in the following order: seed propagation > scaling > tissue culture. Bulblet fresh weights just before planting and BFW at harvest showed an almost proportional relationship regardless of the species, whereas the slope decreased as the bulblet fresh weight exceeded 1.5 g. In terms of species, genetically close L. amabile and L. lancifolium had high BERs, and L. cernuum had a relatively low BER. In conclusion, with regard to bulb production of four Korean native species belonging to the Sinomartagon section, regardless of the propagation method used to obtain bulblets, wet cold storage without planting the bulblets in autumn and subsequently planting them in an open field or greenhouse in the spring for intensive management would be the key to bulb production.
