Most spinal meningiomas have an intradural or partly extradural location. The meningothelial origin is the most common pathologic type of spinal meningioma. Pure extradural spinal meningiomas are not common, and lymphoplasmacyte-rich meningioma (LPRM) is very rare. We report a case of isolated extradural spinal meningioma in the thoracic spine that was pathologically confirmed as LPRM.

Modern fashion manifests in forms that mirror the diverse lifestyles and personalities of consumers. It transcends mere aesthetic designs and embodyies practicality. There is a preference for comfortable, highly functional attire, leaning towards easy wear. Casual wear, in particular, embraces a sense of freedom not found in standard business attire. It seeks a comfortable, natural silhouette through tactile fabrics rather than sportswear. Loose, drop shoulder sleeves enhance comfort and mobility and often become key elements in casual wear designs. Given that clothing must balance aesthetics with functionality, especially across various activities, it is natural to prioritize functional design. Research on patterns suited for dynamic conditions is imperative. The rise of drop shoulder styles necessitates the development of corresponding sleeve patterns. It is crucial to differentiate pattern drafting methods due to the resulting silhouette variations. This study aims to categorize drop shoulder pattern drafting techniques based on shoulder extension and angle dimensions. Each method will be examined, and drop shoulder sleeve patterns and wear forms will be studied using a 3D virtual system. This research holds significance in providing valuable insights and foundational data for designing diverse drop shoulder sleeve patterns, contributing to their practical development and advancement.

Objectives: This study aimed to investigate the effects of conscious sedation on patient satisfaction with dental treatment. Methods: The survey included questions on the patients' general characteristics, dental treatment fear, anxiety, and satisfaction, and patient evaluation by an observer. Statistical analyses were performed using SPSS 20.0 ver. and data were analyzed using frequency analysis, independent t-test, Pearson's correlation coefficient, and multilinear regression analysis. Results: Patients who received conscious sedation therapy showed significantly lower levels of dental fear and anxiety, whereas their dental treatment satisfaction was significantly higher than that of patients who received regular dental treatment (p<0.05). Dental treatment fear, anxiety, satisfaction, and conscious sedation depth were significantly correlated in patients who received conscious sedation therapy (p<0.05). Factors influencing dental treatment satisfaction included age, weight, use of medication, smoking habits, use of conscious sedation therapy, dental treatment fear and anxiety, and conscious sedation depth (p<0.05). Conclusions: Conscious sedation therapy can be an effective method to reduce dental treatment fear and anxiety and improve patient satisfaction.

1. Objectives Recently there have been studied the trials to take out the characteristics of Sasangin's face. But there is not the report of the basis of Sasangin's face. So I want to exchange between Sasang Constitutional Medicine (SCM) and others ; metrology, technology, psychology, ete. 2. Methods I searched documents of Lee Jae-ma and one's junior. I maid a comparative study of each Sasangin's face through them. And I counted each item to find out the major review point of Sasangin's face. 3. Results and Conclusions We found out Sasangin's face has their own characteristics; first impression, forehead, eyes, nose, ears, mouth, voice. And 'First Impression' is the major factor to check the review point of the face for the classification of sasangin through the 9 documents. In the future we have to prove the contents of these clinically. And we have to research the measurement of the face.

1. Objectives We are going to develope 3D Face Recognition Apparatus to analyse the facial characteristics of the Sasangin. In the process, we should identify the recognition rate of the three dimensional position using this Apparatus. 2. Methods We took a photograph of calibrator($280{\times}400mm$) with interval of 20mm longitudinal direction of 10 times using 3D Face Recognition Apparatus. In the practice, we obtained 967 point to the exclusion of points deviating from the visual field of dual camera. And we made a comparison between measurement values and three dimensional standard values to calculate the errors. 3. Results and Conclusions In this test, the average error rate of X axis values was 0.019% and the maximum error rate of X axis values was 0.033%, the average error rate of Y axis values was 0.025% and the maximum error rate of Y axis values was 0.044%, the average error rate of Z axis values was 0.158% and the maximum error rate of Z axis values was 0.269%. This results exhibit much improvement upon the average error rate 1% and the maximum error rate 2.242% of the existing 3D Recognition Apparatus. In conclusion, we assessed that this apparatus was adaptable to abstract the facial characteristic point from three dimensional face shape in the mechanical aspects.

Objectives: This study was undertaken in order to evaluate by work space zoning and structure the concentrations of biological contaminants in the indoor air of domestic office buildings. Methods: Air samples were collected in the office spaces of 15 office buildings in Seoul from June 28 to July 28, 2011. Prior to the sampling, each office was classified into 'open-plan office', 'cellular office' and 'mixed office' according to the work space zoning. To evaluate the biological contamination of indoor air, total suspended bacteria (TSB), Gram positive bacteria (GPB), Staphylococcus aureus (S.A), Methicillin-resistant Staphylococcus aureus (MRSA), Gram negative bacteria (GNB) and fungi were investigated. During the sampling, temperature, relative humidity and carbon dioxide ($CO_2$) were measured. Results: The TSB concentrations ($GM{\pm}GSD$) were $452({\pm}1.3)cfu/m^3$ in open-plan offices, $366({\pm}1.3)cfu/m^3$ in cellular offices and $287({\pm}1.5)cfu/m^3$ in mixed offices, and there were significant differences between the three groups (p<0.05). The highest concentrations ($GM{\pm}GSD$) of fungi were found in the indoor air of cellular offices $128({\pm}1.0)cfu/m^3$, which was at least three times higher than the concentrations in mixed offices $43({\pm}1.0)cfu/m^3$ (p<0.05). Conclusions: Microbiological contamination in the indoor air of office buildings by work space structure was the highest with the open-plan office layout which includes no high walls or doors separating the occupants.

The purposes of this study are to classify consumption values and to examine the effects of consumption values on appearance management behaviors. Questionnaires data was obtained through adults over 20 years old of age (N=478) in Gyeonggi-do, Daegu and Kyungpook regions. Descriptive statistics, factor analysis, multiple regression analysis, t-test and ANOVA were applied. The results of this study are as follows. First, consumption values are composed of three factors such as differential value, material value and practical value. Appearance management behaviors are identified such as surgery/skin care, clothing care, weight training and hair care. The weight training in appearance management behaviors is the most preferred behavior. Second, the results of regression analysis are like as follows: The effects of consumption on plastic surgery/skin care are explained by the differential value, material value and practical value(-). On weight training and hair care, the differential value and material value have positively significant effects. The differential value has significant effects on all over appearance management behaviors. Third, there are signigicant differences in consumption values and appearance management behaviors according to demographic variables. The single, females in 20s and 30s with higher monthly income and payment have higher differential value and lower practical value. The single and female in 20s and 30s were more involved in appearance management behavior.

Objectives: Osteoporosis is characterized by bone loss and morbidity with osteoporotic fracture. In this study, the author aimed to evaluate the effect of dried roots of Rehmannia glutinosa extract (RGE) on osteoblast proliferation in murine calvarial cells. Methods: The osteoblast separated from murine calvariae was cultivated for 6 days and evaluated the cell function. After the addition of RGE on the culture medium, we determined the effect of RGE on the cell viability, cell proliferation, protein synthesis, alkaline phosphatase activity, collagen synthesis and calcified nodule formation of the cultivated osteoblast. Results: The results were summarized as follows. 1. RGE did not change the survival rate of rat calvarial osteoblast. 2. RGE increased the proliferation of rat calvarial osteoblast. 3. RGE increased ALP activity of rat calvarial osteoblast., 4. RGE slightly affected protein synthesis of rat calvarial osteoblast. 5. RGE increased collagen synthesis of rat calvarial osteoblast. 6. RGE slightly affected calcified nodule formation of rat calvarial osteoblast. Conclusions: From these results, it is concluded that RG might improve the osteoporosis resulted from augmentation of osteoblast proliferation.

This study was performed to establish a single residue analytical method for determining fungicide carpropamid residues in various agricultural commodities. Korean cabbage, apple, brown rice and green pepper were selected as representative crops. Samples were homogenized, extracted with acetone and purified by liquid-liquid partition and Florisil column chromatography. Carpropamid residues were analyzed at 220 nm with reversed phase HPLC equipped octylsilyl and octadecylsilyl column and confirmed using mass spectrometry. ILOQ (Instrumental limit of quantitation) of carpropamid was 2 ng and MLOQ (Method LOQ) was 0.02 mg/kg. Mean recoveries from four kinds of crop samples fortified at three levels (MLOQ, 10LOQ, 100LOQ) in triplicate were in the range of 84~112%. Relative standard deviations of the analytical method were all less than 10%, irrespective of crop types.

The formation of niobium oxide microcones on niobium substrates was investigated in NaF to the HF electrolytes. This condition builds on the uniqueness of the microstructures niobium oxide. The dimensions and integrity of the bulk microstructures were found to be strongly dependent on potential, temperature, electrolyte composition, and anodization time. The anodic oxide was initially amorphous at all temperatures, but crystalline oxide nucleated during anodization. From XRD patterns of the anodized specimens, the microcones consisted of crystalline $Nb_2O_5$. We demonstrated niobium oxide microcone structures with nanorods. The anodized niobium oxide microcone texture revealed nanorod bundles. The surface of $Nb_2O_5$ microcones is very regular and has a nano-scale. The surface morphologies of the nanorods were examined using FE-SEM. EDS analyses show that the anodically prepared niobium oxide consists of $Nb_2O_5$. The aim of this study is to find the condition of forming the favorable nanorods by anodization method.
