This study focused on the evaluation of the quality and sensory characteristics of salad dressing prepared from soy powder (Gochujang), in order to increase the level of usability for the Gochujang which is the representative seasoning and spice of Korea. The moisture content and pH of the salad dressing increased in proportion to the increasing amount of soy powder (Gochujang) (p<0.001). Regarding the sugar and salt contents, 20% of the soy powder (Gochujang) shows $26.17^{\circ}Brix$, While the largest value for salt content was 4.8%, with a significant difference existing among varivous samples (p<0.001) As the added amount of soy powder (Gochujang) increased, the sugar content of the salad dressing increased with a statistically significant change (p<0.001). Regarding chromaticity, when soy powder (Gochujang) was added the levels of lightness and yellowness showed a decreasing tendency, and the level of redness showed an increasing tendency, with a significant difference existing among various samples(p<0.001). The results of a sensory showed that, as the amount of added soy powder (Gochujang) increased, the color intensity, Gochujang flavor, and hot taste increased (p<0.001). The results of a sensory showed that, as the amount of added soy powder (Gochujang) increased, the Salad dressing of the glossy, sour flavor, sour taste, and oily level decreased tendency (p<0.001). The results of an acceptance test showed that a 15% content of the soy powder (Gochujang)showed the greatest acceptance values in categories such as appearance, taste, texture, and overall acceptability. Therefore, when making a salad dressing with Gochujang, it is appropriate to add a 15% content of Gochujang to improve the quality and sensory characteristics of the salad dressing.

This paper is to investigate the retrofitting effect for a non-seismic reinforced concrete frame strengthened by perimeter steel moment frames with indirect integrity, which ameliorates the problems of the direct integrity method. To achieve this, first, full-scale tests were conducted to address the structural behavior of a two-story non-seismic reinforced concrete frame and a strengthened frame. The non-seismic frame showed a maximum strength of 185 kN because the flexural-shear failure at the bottom end of columns on the first floor was governed, and shear cracks were concentrated at the beam-column joints on the second floor. The strengthened frame possessed a maximum strength of 338 kN, which is more than 1.8 times that of the non-seismic specimen. A considerable decrease in the quantity of cracks for the strengthened frame was observed compared with the non-seismic frame, while there was the obvious appearance of the failure pattern due to the shear crack. The lateral-resisting capacity for the non-seismic bare frame and the strengthened frame may be determined per the specified shear strength of the reinforced columns in accordance with the distance to a critical section. The effective depth of the column may be referred to as the longitudinal length from the border between the column and the foundation. The lateral-resisting capacity for the non-seismic bare frame and the strengthened frame may be reasonably determined per the specified shear strength of the reinforced columns in accordance with the distance to a critical section. The effective depth of the column may be referred to as the longitudinal length from the border between the column and the foundation. The proposed method had an error of about 2.2% for the non-seismic details and about 4.4% for the strengthened frame based on the closed results versus the experimental results.

Lymphangioleiomyomatosis is a rare disease which afflicts young women of childbearing age. We experienced a 32-year-old female who was admitted because of worsening exertional dyspnea after hormonal therapy with Clomifen for five months and intermittent hemoptysis. Chest PA showed diffuse ground glass appearance with some reticular infiltrations. High resolution CT scan showed multiple small thin walled cysts distributed homogeneously throughout the entire lung. Pulmonary function test showed characteristic obstructive pattern despite the restrictive interstitial pattern of chest radiography. Thoracoscopic lung biopsy specimen showed abnormal proliferation of smooth muscle cells in the walls of lymphatic vessels, bronchioles, and pulmonary vessels typical of pulmonary lymphangioleiomyomatosis. Hormonal therapy with medroxyprogesterone was initiated.

PURPOSE. This study investigated the effect of amount of thickness reduction on color and translucency of dental monolithic zirconia ceramics. MATERIALS AND METHODS. One-hundred sixty-five monolithic zirconia specimens ($16.3mm{\times}16.3mm{\times}2.0mm$) were divided into 5 groups (Group I to V) according to the number of A2-coloring liquid applications. Each group was then divided into 11 subgroups by reducing the thickness up to 1.0 mm in 0.1-mm increments (Subgroup 0 to 10, n=3). Colors and spectral distributions were measured according to CIELAB on a reflection spectrophotometer. All measurements were performed on five different areas of each specimen. Color difference (${\Delta}E^*{^_{ab}}$) and translucency parameter (TP) were calculated. Data were analyzed using one-way ANOVA and multiple comparison $Scheff{\acute{e}}$ test (${\alpha}=.05$). RESULTS. There were significant differences in CIE $L^*$ between Subgroup 0 and other subgroups in all groups. CIE $a^*$ increased (0.52<$R^2$<0.73), while CIE $b^*$ decreased (0.00<$R^2$<0.74) in all groups with increasing thickness reduction. Perceptible color differences (${\Delta}E^*{^_{ab}}$>3.7) were obtained between Subgroup 0 and other subgroups. TP values generally increased as the thickness reduction increased in all groups ($R^2$>0.89, P<.001). CONCLUSION. Increasing thickness reduction reduces lightness and increases a reddish, bluish appearance, and translucency of monolithic zirconia ceramics.

This study aimed to find the components of visual image by researching main image-related adjectives applied to high-waist skirts. In addition, it compared and analyzed the differences and mutual influences of visual images according to variations in the waistline and skirt length of high-waist skirts. The researchers made nine high-waist skirts-combinations of three different levels of waistlines and skirt lengths. The test involved 121 people who hold degrees in the field of Clothing and Textiles. The panels tested actual images of all models wearing the high-waist skirts shown on a computer screen. The results of the study are as follows.: Four factors affected the visual image as waist-height and skirt-length changed: attractiveness, upper-body compensation, length compensation, and hips compensation. Among these factors, attractiveness was estimated as the most important factor. The torso and the hip were highlighted as the waistline increased from 3cm to 11cm, due to the optical illusion of a tighter skirt wrapping the bust, waist, and hips. As the waistline increased, the stature and leg length increased, possibly revising the overall appearance. For the skirt length, a length measuring 20cm above the knees, proved to be most attractive. This resulted in elongated height and leg length, and a slimmer overall look.

Blossom blight in strawberry was first observed in a green house in Nonsan, Damyang, and Geochang areas of Korea, between early January to April of 2012. Disease symptoms started as a grey fungus formed on the stigma, which led to the blossom blight and eventually to black rot and necrosis of the entire flower. We isolated the fungi purely from the infected pistils and maintained them on potato dextrose agar (PDA) slants. To test Koch's postulates, we inoculated the fungi and found that all of the isolates caused disease symptoms in the flower of strawberry cultivars (Seolhyang, Maehyang, and Kumhyang). The isolates on PDA had a velvet-like appearance, and their color ranged between olivaceous-brown and smoky-grey to olive and almost black. The intercalary conidia of the isolates were elliptical to limoniform, with sizes ranging from $5.0{\sim}10.5{\times}2.5{\sim}3.0{\mu}m$ to $4.0{\sim}7.5{\times}2.0{\sim}3.0{\mu}m$, respectively. The secondary ramoconidia of these isolates were 0- or 1-septate, with sizes ranging betweem $10.0{\sim}15.0{\times}2.5{\sim}3.7{\mu}m$ and $8.7{\sim}11.2{\times}2.5{\sim}3.2{\mu}m$, respectively. A combined sequence analysis of the internal transcribed spacer regions, partial actin (ACT), and translation elongation factor 1-alpha (TEF) genes revealed that the strawberry isolates belonged to two groups of authentic strains, Cladosporium cladosporioides and C. tenuissimum. Based on these results, we identified the pathogens causing blossom blight in strawberries in Korea as being C. cladosporioides and C. tenuissimum.

The main objective of this research was to understand the latest trends of natural print design through the quantitative & qualitative analysis of fashion appeared in contemporary female collections. The research criteria was defined as 3 seasons from 2011 S/S to 2012 S/S. Data collection of 726 was done through review of 'pr$\hat{e}$t-$\grave{a}$-porter Collections' of three major fashion cities; Paris, Milan and NY. Statistical analysis of frequency with chi-square test was conducted. Also qualitative interpretation of natural print design' characteristics was completed. The main findings were as follows.; The average occurrence rate of natural print design from 2011SS to 2012 SS in three collections were 6.4% in Milan 6.4%, 5.5% in Paris and 6.8% in N.Y. The five source types of natural prints in contemporary women's fashion collections were identified and the order of their appearance were as follows: flowers, plants, animals, insects & marine organisms and compound one. The plant prints were expressed by stylized or realistic touch. Flower patterns showed more variables than plants, however, there were no big difference in their image and major characteristics. The animal prints demonstrated two aspects. First one used typical animal print of fur or skin, but the other one draw the animal figure like paintings. The compound source type presented the most interesting and fresh pattern design ideas. In the insects & marine organisms, mainly butterfly and seashell & starfish, etc. appeared as real shapes or sometimes were stylized.

The aim of this study is to examine the effects of the story sharing activity on-conflicting situations by the use of children's story on the theory of mind and peer competences of preschoolers so that appropriate teaching materials can be allocated for the actual preschool education site. The subjects of this study were 46 preschoolers under the age 4 at the attached kindergarten of P University in Pohang City, Gyeongbuk and in which 23 children among them were assigned to a test group and the other 23 to a control group. The collected data was analyzed by SPSS ver. 15.0 program and Cronbach's ${\alpha}$ coefficient was yielded to verify the reliability for each scale. The multivariate analysis of covariance (MANCOVA) was conducted. The analysis results are as follows. First, the story sharing activity on conflict situations by using children's story had a significant effect on the preschoolers' general appearance and actual task as sub-factors of the theory of mind, whereas no significant effects were found regarding the content change task and position change task. Second, the story sharing activity on conflict situations by using children's story had significant effect on the preschoolers' overall sensitivity, insecurity and pro-sociability as sub-factors of the peer competences, whereas no significant effects were found regarding the aggression, exclusivity and anti-sociability.

Electrokinetics technology is proposed for improving the recovery metals ion and oil from clay-sandy soil. In order to restore or extract them from clay-sandy soil, the gas produced by anode chamber is re-injected to the clay-sandy soil(sample). Samples produced in this study were completed to verify the proposed performance for 7 days by gradually increasing the pressure to the final pressure of 30psi($2.11kgf/cm^2$) through the compression process. Before compression, the copper rings were inserted into the sample, allowing us to observe the changes in appearance of copper ring after the end of the experiment. In this study, pressurized module and non-pressurized module were tested, respectively. The condition of test is a continuous process and the voltage gradient is 2V/cm during 24 hours. As a result, the efficiency of pressurized module is better than non-pressurized module.

In this paper, we provide an authentication technology for verifying dynamic signature made by finger on smart phone. In the proposed method, we are using the Auto-Encoder-based 1 class model in order to effectively distinguish skilled forgery signature. In addition to the basic dynamic signature characteristic information such as appearance and velocity of a signature, we use accelerometer value supported by most of the smartphone. Signed data is re-sampled to give the same length and is normalized to a constant size. We built a test set for evaluation and conducted experiment in three ways. As results of the experiment, the proposed acceleration sensor value and 1 class model shows 6.9% less EER than previous method.
