The effectiveness of Palmarosa and Neroli essential oil on dry skin of rat induced by kitchen detergent are investigated. The experimental groups were divided the control group (C), group treated with surfactant (A1), group treated with Palmarosa (A2), group treated with Neroli (A3), group treated with Palmarosa and Neroli (A4). The protein analysis of all experimental groups was performed with SDS polyacrylamide gel electrophoresis and observation of epidermis and the alteration of mast cell were performed with photomicroscope. According to the protein analysis, the A3 group treated with Neroli essential oil was appeared the most similar with the control group. And then the A4 group treated with Palmarosa + Neroli essential oil was appeared the most similar with the control group. According to the results of morphologic view with keratin layer, the keratin layer's breakaway resulting from Palmarosa essential oil, the keratin layer's restoration resulting from Neroli essential oil was appeared. And then the structure of the epidermal layer was preserved by hyperkeratosis reaction. In photomicrosopic obersevation of mast cell to examine the inflammatory reactions, the increase in size and number of mast cell were showed in A1 group treated with surfactant compared to the control group (C). The number of mast cells definitely decreased in groups (A3, A4) which were treated with Neroli essential oil.

With the recent increased risk of livestock disease spread and human infection, livestock disease control has become very important. Consequently, there has been an increased attention on an implantable real-time monitoring and traceability system for individual cattle. Therefore, we have developed a robust monitoring and traceability system based on an implantable MFAN/RFID sensor tag. Our design combines the MFAN technology that is capable of robust wireless communication within cattle sheds and the 900MHz RFID technology that is capable of wireless communication without battery. In MFAN/RFID implantable sensor tag monitoring system, UHF sensor tag is implanted under the skin and accurately monitors the body temperature and biological changes without being affected by external environment. In order to acquire power needed by the tag, we install a MFAN/RFID tranceiver on the neck of cattle. The MFAN coordinator passes through the MFAN node and the RFID-reader-combined MFAN/RFID transceiver and transmits/receives the data and power for the sensor tag. The data stored in the MFAN coordinator is transmitted via the internet to the livestock history monitoring system, where it is stored and managed. By developing this system, we hope to alleviate the problems related to livestock disease control.

There are some cases in trouble with monitoring emergency patient by existing electrode sensor in measuring instrument in home and hospital etc. And there are problem to measure because of coming down electrode in emergency car or vessel of shaking and fat, humidity of patient. In this study, it has designed band-type for patient to put on the breast easily and go around anywhere freely putting band electrode on his body. Gold has used as electrode material in this electrocardiogram because of its excellent electronic resistance peculiarity and no trouble with skin. And it is able to monitor multi-body-signal by additional design of periphery temperature. There are good results of body signal transmission in the breast or the rib, and get a little body signal in abdomen. We get a result it is better case of gold than usual electrode on signal detection, and know usual electrode was disposable, but we have more correct result from gold electrode sensor, being semi-permanent ana. great contact ability even if movement.

Purpose: Gluteal perforator is easily identified in the gluteal region and gluteal perforator flap is a very versatile flap in sacral sore reconstruction. We obtained satisfying results using the gluteal perforator flap, so we report this clinical experiences with a review of the literature. Methods: Between November of 2003 and April 2006, the authors used 16 gluteal perforator flaps in 16 consecutive patients for coverage of sacral pressure sores. The mean age of the patients was 47.4 years (range, 14 to 78 years), and there were 9 male and 7 female patients. All flaps in the series were supplied by musculocutaneous arteries and its venae comitantes penetrating the gluteus maximus muscle and reaching the intrafascial and suprafascial planes, and the overlying skin forming a rich vascular plexus arising from gluteal muscles. Patients were followed up for a mean period of 11.5 months. Results: All flaps survived except one that had undergone total necrosis by patient's negligence. Wound dehiscence was observed in three patients and treated by secondary closure. There was no recurrence during the follow-up period. Conclusion: Gluteal perforator flaps allow safe and reliable options for coverage of sacral pressure sores with minimal donor site morbidity, and do not sacrifice the gluteus maximus muscle and rarely lead to post-operative complications. Freedom in flap design and easy-to perform make gluteal perforator flap an excellent choice for selected patients.

Background and Objectives: Surgical ablation of tumors in the oral cavity and the oropharynx results in a three dimensional defect because of the needs to resect the adjacent area for the surgical margin. Although a variety of techniques are available, radial forearm free flap has been known as an effective method for this defect, which offers a thin, pliable, and relatively hairless skin and a long vascular pedicle. We report the clinical results of our 54 consecutive radial forearm free flaps used for oral cavity and oropharynx cancers. Materials and Methods: We reviewed the medical records of patients who were offered intraoral reconstruction with a radial forearm free flap after ablative surgery for oral cavity and oropharyngeal cancers from August 1994 to February 2003 and analyzed surgical methods, flap survival rate, complication, and functional results. Among these, 20 cases were examined with modified barium swallow to evaluate postoperative swallowing function and other 8 cases with articulation and resonance test for speech. We examined recovery of sensation with two-point discrimination test in 15 cases who were offered sensate flaps. Results: The primary sites were as follows : mobile tongue (18), tonsil (17), floor of mouth (4), base of tongue (2), soft palate (2), retromolar trigone (3), buccal mucosa (1), oro-hypopharynx (6), and lower lip (1). The paddles of flaps were tailored in multilobed designs from oval shape to tetralobed design and in variable size according to the defects after ablation. This procedures resulted in satisfactory flap success rate (96.3%) and showed good swallowing function and social speech. Eight of 15 cases (53.3%) who had offered sensate flap showed recovery of sensation between 1 and 6 postoperative months (average 2.6 month). Conclusion: The reconstruction with radial forearm free flap might be an excellent method for the maximal functional results after ablative surgery of oral cavity and oropharyngeal cancers that results in multidimensional defect.

Objective: This study aims to assess the following issues - acquisition level in terms of the information on frequently used drugs of youth, access paths for the information, actual status of the use of drugs frequently used by youth, types of the used drugs, drug abuse among youth, and the consequent drawbacks. This study also takes aims at suggestion of correct role of pharmacists in consideration of drug abuse among youth. Methods: During the period from August 1, 2011 to October 31, 2012, a research design and a question development have been conducted. To the students of the schools that were randomly selected (elementary school's N=99, middle school's N=106, high school's N=115 and university's N=115), it was asked to complete given questionnaire from August 1, 2012 to August 31, 2012. During the period from September 1, 2012 to October 30, 2012, the questionnaires were collected back and the analysis and evaluation of them were carried out. Results: Drugs known to the respondents were a total of 115 different medicines and most of the drugs belonged to over-the-counter drugs. The most well known drug was pain reliever and the second most familiar drug was wound ointment. Most of the respondents found the drugs through direct use and advertisement. In everyday life, more than half of the respondents were using over-the-counter drugs as well as health supplements. The most commonly used drug was analgesic drug. It was showed that the respondents also frequently used the drugs for improving their grades and appearances. It was shown that among the cases of drug use, there were also the cases of misuse and abuse of drugs for the respondents or people around them. Reliability of pharmacists was shown to be high and many students were also satisfied with the pharmacists' guidance for medication. Conclusion: Currently many students are using different kinds of drug in daily life, and there is a possibility that the risk of misuse and abuse of drugs will be increased. Those age groups can easily engage in bad habit of drug use. Thus, promotion on accurate drug information has to be strengthened, and pharmacists are required to conduct correct guidance for drug user's medication in terms of use amount, usage, interactions among different drugs, and potential risks.

A larger energy consumption and concentration of population induced green house gas glowing and heat island effect in the urban space. Roof green system was a effect method to reduce green house gas and heat concentration in the city. Therefore, construction of this system was increasing. Most of lightweight soil used in roof green system was perlite, but this caused dust and skin disease. So it needed to develop another new lightweight soli for roof green system. Meanwhile, a thermoelectric power plant generated bottom ash as a by-product. According to previous research, bottom ash could be used for artificial lightweight soil with 60 wt% of mixing rate. But this study was proceed to develop a artificial lightweight soil using bottom ash with higher mixing rate by 65 wt% and different organic ingredients. First, physical and chemical properties of bottom ash was investigated. Then test according to landscaping design standard was proceeded for various artificial lightweight soil mix types using bottom ash, bark, compost and coco peat. As a result, the artificial lightweight soil with 65% of bottom ash, 30% of bark and 5% of compost was suitable for low and middle range of soil standard.

As the global large-scale infrastructure construction market expands, the construction of civil engineering structures in extreme environments such as cold or hot regions is being planned or constructed. Accordingly, the construction of the pile foundation is essential to secure the bearing capacity of the upper structure, but there is a concern about loss of stability and function of the pile foundation due to the possibility of ground deformation in extreme cold and hot regions. Therefore, in this study, a new type of pile foundation is developed to respond with the deformation of the ground, and the ground deformation that can occur in extreme cold and hot region is largely divided into heaving and settlement. The new type of pile foundation is a form in which a cylinder capable of shrinkage and expansion is inserted inside the steel pipe pile, and the effect of the cylinder during the heaving and settlement process was analyzed numerically. As a result of the numerical analysis, the ground heaving caused excessive tensile stress of the pile, and the expansion condition of the cylinder shared the tensile stress acting on the pile and reduced the axial stress acting on the pile. Ground settlement increased the compressive stress of the pile due to the occurrence of negative skin friction. The cylinder must be positioned below the neutral point and behave in shrinkage for optimum efficiency. However, the amount and location of shrinkage and expansion of cylinder must comply with the allowable displacement range of the upper structure. It is judged that the design needs to be considered.

This paper is to find the theme and meaning of the Beauvais Grotesque tapestry considered a conundrum. The three works are chosen from Beauvais Grotesque consisting of six tapestries, which are The Offering to Pan, The Musician and Dancers, The Camel in the J. Paul Getty Museum. I analyzed these works by dividing them into grotesque ornaments, chinoiserie motifs, and scenography. The Offering to Pan shows the influence of Raphael's Grotesque tapestry, but Beauvais work followed the design of Jean Berain's Grotesque with arabesque. In The Musician and Dancers, chinese ceramics, textiles, and Chinese people in edge were noted. Especially, the Chinese with yellow skin in the border reveals the European gaze on China at that time. In the 18th century, Chinoiserie was prevalent through stage designs rather than books. The Camel, playing Brighella, makes it clear that this tapestry is a stage of Comedia dell'arte. The characteristic of Comedia is a mixture of genres such as music and dance, with no scripting 'improvisation.' Features of Comedia are 'improvisation' without a script and a mixture of genres such as music and dance. Thus, the Grotesque tapestry transfers the stage of the Comedia into threads woven. In addition, the horizontal stage decoration with the disappearance of the perspective vanishing point is related to the era of regent of Philippe d'Orl?ans (1674-1723). Above all, the grotesque, Chinoiserie, and scenography are all fantasies separated from reality. Therefore, the Beauvais Grotesque tapestry represents of 'improvisation' and 'fantasy' in which there is no narrative theme or meaning, as if the script of Comedia did not exist.

Snow fungus (Tremella fuciformis) with functional contents has satisfactory effects on various diseases, including atherosclerosis, high cholesterol, healthy skin, cancer, diabetes, and anti-inflammation. In this study, the extraction yield and functional contents (ergothioneine and 𝛽-glucan) of white jelly fungus were compared based on the extraction conditions using response surface methodology. Results revealed the extraction conditions for optimization of the dependent variables to be 60℃ and 4.33 h, when 16.6 mg/mL of sample concentration was used. Under these conditions, the extraction yield was 24.9%, including ergothioneine (66.8 ㎍/g) and 𝛽-glucan (34.9 g/100 g). These results can be useful in understanding the functional ingredients and mass extraction process in mushroom.
