Fine needle aspiration cytology (FNAC) of thyroid gland lesions has become a routine diagnostic method. And fine needle aspiration cytology is considered a safe, reliable and cost-effective means of selecting thyroid nodules with risk for malignancy. However, fine needle aspiration cytology of the thyroid may cause hemorrhage, infection, or trauma to adjacent structures. Hemorrhage sufficient to cause tracheal compression has not been reported. So we present a case of anterior neck hematoma causing tracheal compression after FNAC of the thyroid nodule.

Risk level for each construction work can be very important factors to establish advanced preventionmeasures. But it is important how to produce it. There are three different methods to set it up for consturuction situation. They are as follows; 1) occurrence frequency = the number of accident workers of each work kind / yearly accident workers 2) occurrence frequency = the number of accident workers of each work kind / yearly workers 3) occurrence frequency = the number of accident workers of each work kind / the total workers All these three concepts(=averaged concept)are analyzed. Additionally frequency based on discrete curve, and severity based on continuous curve are also combined for producing risk level with more scientific approach. This risk level can be very useful to make prevention plan or take measures at construction sites. This is study result can change existing risk level concept to new concept of it, namely rail way work and in-water work showed be high risk level and RC work be low risk level, different from the situation which we have thought commonly, so far.

There are many countermeasures collected by field experts, safety managers with their subjective decisions, without analysis. Subcontractor does not know which one of those can be more defective countermeasures. More weighted countermeasures should be taken for subcontractor's economical aspects. But there are almost no measures with useful weight so that subcontractors can select some as they need more effective even though there are not many measures at construction sites. AHP technique has been introduced into the analysis of counter measures for subcontractor. Countermeasures which car collected from field-experienced safety engineers have been weighed with frequency rate saying how many responders selected. And then, they are analyzed by AHP Technique for making out relative important level of the countermeasures, by each step such as Direct, Indirect, Management level, and policy level, quantitatively. AHP level in the study is composed of two stories, not three stories, in order to make respondents easier when they are asked. At least 15-year-experienced expert are asked for AHP questionnaire.

The characteristics of primary cultured rat brain microvessel endothelial cells (RBMECs) were studied using microscopy, immunohistochemistry and measuring of transendothelial electrical resistance (TER). The RBMECs formed a monolayer by $5{\sim}6$ days after plating and showed characteristics of whirling appearance. The TER increased until day 5 and decreased then. There was few immunoreaction with anti-GFAP, anti-GalC, anti-neurofilament 160/200 kD antibodies. So the contamination of astrocyte, oligodendrocyte, and neuron. could be ruled out.. Immunoreaction to vWF antigen was widespread througout the cytoplasm as Weibel-Palade granule. Immunoreaction to tight junction proteins, i.e. occludin, ZO-1, and ZO-2 was seen at cell contact. In summary, RBMECs isolated and cultured showed morphological, immunohistochemical and electrical characteristics of blood-brain barrier (BBB). The in vitro BBB model can be used in studying characteristics of in vivo BBB.

For the treatment of the dye wastewater, a polyamide nano-composite membrane and reverse osmosis (RO) membranes were prepared using interfacial polymerization technique, in which piperazine, meta-phenylene diamine, and trimesoyl chloride were used as monomers, Their permselective properties were characterized with aqueous solutions of PEG 600, $Na_2SO_4$, and NaCl, and their performance was compared with that of Osmonics Co, They were found to be a typical nano-composite membrane and a low pressure RO membrane. Using them, a real dye wastewater supplied from the Kyungin Corporation, one of the domestic dye producer, was treated, studying the separation performances of the membranes, Also, during the wastewater treatment, cleaning in place (CIP) of the membranes was carried out regularly to recover the flux of the membranes. Three different chemical cleaners were employed for the CIP process and their performance were compared in this study.

Objectives : This study was performed to research trends in Korean medicine treatment of diabetes mellitus (DM). Methods : We reviewed 73 studies about diabetes mellitus, which had been published from 2008 to 2013. The article search was performed on the Korean institute of oriental medicine (KIOM) database. Results : 1. Patterns of study design were as follows : 14 review studies, 44 experimental studies, 7 clinical studies, 8 case reports. 2. From the 14 review studies, we noted that literature studies about definition, pathologic mechanism, treatment, pathologic pattern identification of DM and previous study analyses were done. 3. From the 44 experimental studies that are the most common type of DM studies, various Korean medicine treatments such as single medicinal herbs, herbal complexes, diets and pharmacopuncture were used. Anti-diabetic effects were demonstrated in most of the studies. 4. 7 clinical studies about acupuncture, electroacupuncture, herbal medicine, etc. were reported. 5. 8 cases about DM complications and comorbidities were reported. Clinical symptoms improved in all of studies, blood sugar level decreased in four studies. Conclusions : Further clinical and case study based on experimental researches should be performed.

This study was performed in order to identify nutritional factors affecting on skin sebum content with 131 female university undergraduates in 2003. We measured the sebum contents of 4 facial spots to classify their skin types. Daily energy and nutrient intakes of the subjects were not deficient except in calcium and iron, which were 466.2 mg (66.6% RDA) and 8.5 mg (53.4% RDA) relatively. We observed no significant difference of energy and nutrient intakes among the 3 skin types. But significantly higher consumption of grains and slightly higher frequencies of several food groups (excepting starches) were shown in oily skin types, so they might have higher nutrient intakes. Serum indices and food preferences mostly revealed no difference among the 3 skin types. But in the oily skin type, serum phosphorus levels were significantly lower than others, suggesting phosphorus-rich food consumption like soft drinks and pains could lead to a dry skin type rather than an oily one. Also in the oily skin type, sweet taste preference was slightly tower than others; more-over, sweet intake was lower samely significantly. There was mostly no significant relationship between facial sebum contents and nutrient intakes, dietary behavior, food frequency and food preference except in some factors. Animal protein intake showed a significant negative relationship toward facial sebum content. On the other hand, in normal skin type, Fishes consumed was slightly higher than others, so that higher animal protein consumption presumably leads to normal skin type. Frequency of fried food and bacon and preference of fried foods showed slightly negative relationships toward facial sebum content. Regular meal times showed significantly increased facial sebum content.

Introduction: SLE is autoimmune disease to appear systemic pathology in the connective tissue. Perniotic LE is sub-type of chronic dermal LE which causes purple macules on the terminal part of body-nose, ends of fingers, heals, calfs of the legs, elbows and knees. Objective: The purpose of this study was to estimate the efficiency of oriental medical treatment and management on the SLE and perniotic LE. Subject: We studied 2 patients who visited and hospitalized in Daejon University Oriental Hospital Dept. of Dermatology, with SLE and pemiotic LE from April 2002 till May 2002 Method: We treated them with herb medication, acupuncture and in addition to we consulted western medication if they were needed Results: In case of SLE patient, we considered it to be Yeol-Dok-Chi-Seong, so we priscriped Ga-Mi-So-Dok-Eum1, 2 , Yang-Dok-Baek-ho-Tang first. and till 22 days of hospitalization, we considered to be Gi-Eum-Yang-Heo and priscriped Ji-Hwang-Tang-Hab-Cheong-Sim-Yeon- Ja -Eum-Ga-Mi. but it wasn't adjust and high fever was reaccurred. And till 24 days of hospitalization we priscriped Gal-Geon-Hae-Gi-Tang, and becomed to 25 days, high fever was disappeared and the patient discharged and she has remained generally good condition. In case of Perniotic LE, at first we misdiagnosed her disease as a acral lentiginous melanoma, and we considered it to be Gan-Soo-Yeol-Li-Yeol- Jeung and priscriped Cheong-Pae-Sa-Gan-Tang and transferred her to another hospital, but she was diagnosed Perniotic LE Conclusion: Considering the above results, in case of SLE, in acute phase, we could treat her with oriental-western treatment, and in relief phase, we could treat her with only oriental treatment very efficiently. but in case of perniotic LE, we misdiagnosed it as a acral lentiginous melanoma, but we could experienced very rare perniotic LE case. And also further study is needed on the SLE, and perniotic LE, and we have to systematize of dyagnosis and treatment system.

Purpose: It is necessary to prepare more groundbreaking measures to prevent recurrence in order to reduce the number of industrial accidents in Korea that occur steadily. In particular, since workers with disabilities are much more vulnerable to disaster safety than non-disabled workers, there is a great need to build a customized safety environment system suitable for the characteristics of the work in which workers with disabilities work and to promote management efficiency. Research design, data and methodology: Based on the analysis of the actual status of safety and health management of workplaces for the disabled, such as small, medium-sized and major businesses in Korea, an app was designed and developed to improve safety and health management efficiency of workplaces for the disabled. First, it was designed so that managers of workplaces with disabilities can understand at a glance key legal information that managers need to know and it was improved to suit the eye level of disabled workers so that they could self-evaluate the risk of their work by applying the risk assessment model for workplaces with disabilities. In addition, a mobile education environment was created in which safety and health education contents suitable for the characteristics of disabled workers can be learned by themselves. Results: When this app is applied to domestic workplaces, it is possible to check the exact contents of occupational safety and health education and easily search and check various legal information anytime, anywhere, allowing managers and disabled workers to quickly and efficiently manage various safety information. Conclusions: In addition, the establishment of a mobile safety and health management system that can quickly identify and clearly respond to various legal standards and risks of workplaces with disabilities can be expected to help prevent industrial accidents at workplaces with disabilities in Korea.
