We propose a noise estimation method using edge detection in moving pictures. Edge detection is to exclude structures and details which have an effect on the noise estimation. To detect edge, we use Sobel and morphological closing operators which are robust to details of images. The proposed noise estimation method is more efficiently applied to noise estimation in various types of moving images and has better results than those of existing noise estimation methods. Also, proposed algorithm can be efficiently applied to image and video applications.

This study aims to investigate how the woman's beauty makeup trend had been changed in 1960s by analyzing the characteristics of woman's make-up in that period. For this study, a lot of documents and papers related to the woman's make-up were collected and reviewed. In particular, to analyze the characteristics of woman's make up trend in 1960s, a lot of women's pictures and makeup-related articles from 143 volumes of woman's magazines such as Yeowon and Jubusaenghwal were collected. Among the 624 pictures, fifty two pictures which were good enough for studying the total face and makeup were used for this study. The period of this study ranges from 1960 through 1969 and the analysis is focused on skin expression, eyebrow, eye shadow, eye line, lipstick, and brusher and through the related articles, the intention and contents of make up. were delivered and found out. The results are as follows. In early 1960s, the woman's make up was characterized by the make up ranging from unnatural and gray skin expression to dense pink skin expression, giving natural and glossy tint onto the skin and in particular putting a bright accent on the eyelid, eye or lip. In the mid-1960s, the make up style expressed skin more naturally, giving more shading on the eyelid, nose and lip, thus having cubic make-up. In the late 1960s, the make up became more refined and harmonized by using colors according to the TPO (time, place and objective) and skin color. The study results show that the women in 1960s pursued the "cute and young looking image" and used the make up to express their images young and cute. In the mid 1960s, the minimalism which pursued the pure and simple make up appeared in US. That trend affected the make up style of Korean women and hence Korean women showed more natural make up style in the mid and late 1960s.

This study studied female Hanbok that appeared in Korean movies in different periods, and investigated the changes and flow of the Hanbok in the movies based on the design and the form. Research scope is limited to Hanbok in Korean movies released between 1950' and 1980', and in order to study Hanbok in movies, snapshots of Korean movies for each period are used. Pictures are sourced from the Korean movie database, and forms and colors of Hanbok in the pictures are classified into 7 categories. Based on this, characteristics, changes and flow of Hanbok for each period are studied. Based on this, by investigating the Hanbok in Korean movies from silhouette and design perspectives and comparing each period, it is found that the following changes have been made: From 1950' to 1980', generally Min Jeogori (Normal Korean traditional jacket) had a higher rate. Up to early 1960', wide collar and collar strip were trends, but from 70' to 80', they have been remarkably narrowed. After liberation, ease and functional elements of western clothing were accepted. From 1950' to 80', generally wide and round shape sleeve were used. Also, from 50' to 80', normally skirt and Jeogori had the same color and fabric. Lastly. as Hanbok with western style fabric, rather than traditional Hanbok fabric was increasing, Hanbok with variously patterned fabric was shown. The lack of colored pictures led of limited research materials, and so a more accurate and sophisticated research on material and design was not possible, However, it is meaningful that this study has investigated changes and flow of Hanbok in modern Korean movies.

The effectiveness of sodium carboxymethylcellulose(SCMC) and dextran 70 in the prevention of adhesion formation in abdominal cavity of rabbits following artificial injuries was elucidated and the effects -of these medicines on blood pictures were also examined. After abrasion treatment on jejunum in gonadotropins primed rabbits, 1, 2 and 3% of SCMC solutions, 6 and 10% dextran 70 solutions and a synthetic solution of 1% SCMC and loft dextran 70 in 0.9% saline solution were infused into the abdominal cavity. Four weeks later the abdominal cavities were reopened under general anesthesia. The synthetic solution showed the highest adhesion reduction rate(100%), while 1% SCMC, 6 and loft dextran solutions showed no significantly evident effect of adhesion prevention. The SCMC solutions showed better adhesion reduction effect than dextran 70 solutions. After infusion of these adhesion preventive medicines, the changes of total leucocytes, erythrocytes, lymphocytes, PCV, plasma fibrinogen and protein contents were examined. No remarkable difference in blood pictures was shown between the synthetic solution and the other medicines. Therefore, it can be suggested that the synthetic solution of 1% SCMC and 10% dextran 70 in 0.9% saline solution at dose of 5$m\ell$/kg of body weight is prominently effective in the prevention of postoperative adhesion formation and wolf be safe in animals and human.

Multi-view video is obtained by capturing one three-dimensional scene with many cameras at different positions. The computational complexity of multi view video coding increases in proportion to the number of cameras. To reduce computational complexity and maintain the image quality, improved prediction structure and motion estimation method is proposed in this paper. The proposed prediction structure exploits an average distance between the current picture and its reference pictures. The proposed prediction structure divides every GOP into several groups to decide the maximum index of hierarchical B layer and the number of pictures of each B layer. And the proposed motion estimation method uses a hierarchical search strategy. This strategy method consists of modified diamond search pattern, progressive diamond search pattern and modified raster search pattern. Experiment results show that the complexity reduction of the proposed prediction structure and motion estimation method over JMVC (Joint Multiview Video Coding) reference model using hierarchical B pictures of Fraunhofer-HHI and TZ search method can be up to 40~70% while maintaining similar video quality and bit rates.

The purpose of this study is to verify the effects of storytelling-centered arts educational activities based on the famous painting appreciation on young children's appreciation ability of pictures and creativity. The study was conducted with a total of 50 5-year-old young children in two classes of B Day Care Center in the city of J, Jeollabukdo. The children were randomly divided into an experimental group(25) and a control group(25). The storytelling-centered arts educational activities based on the famous painting appreciation was conducted for the experimental group for 12 weeks from April 29, 2013 to July 19, 2013. The activities were composed of 3 steps of 'appreciation-expression-exhibition & assessment' on the basis of 2-week basic units. The appreciation activities were composed basing upon the types of the famous painting appreciation and storytelling, and expression and exhibition & assessment activities were composed of 4 areas of arts(music/movement/language/art). The results of the study are as follows. First, the storytelling-centered arts educational activities based on the famous painting appreciation generally improved young children's painting appreciation abilities in all sub-areas(observation and description/artist's intention of subject expression/mood of a work/material and technique/artistic factors/attitude to the work). Second, the storytelling-centered arts educational activities based on the famous painting appreciation generally improved young children's creativities in all sub-areas(originality/fluency/flexibility/imagination).

Application of herbicide for rice cropping is inevitable but notorious for its side effect of environmental pollution. Precision fanning will be one of important tools for the least input and sustainable fanning and could be achieved by implementation of the variable rating technology. If a device to detect weeds in rice field is available, herbicide could be applied only to the places where it is needed by the manner of the variable rating technology. The study was carried out to develop an algorithm of image processing to detect weeds in rice field using a machine vision system of multi-spectral digital images. A series of multi-spectral rice field picture of 560, 680 and 800 nm of center wavelengths were acquired from the 27th day to the 39th day after transplanting in the ineffective tillering stage of a rice growing period. A discrimination model to distinguish pixels of weeds from those of rice plant and weed image was developed. The model was proved as having accuracies of 83.6% and 58.9% for identifying the rice plant and the weed, respectively. The model was used in the algorithm to differentiate weed images from mingled images of rice plant and weed in a frame of rice field picture. The developed algorithm was tested with the acquired rice field pictures and resulted that 82.7%, 11.9% and 5.4% of weeds in the pictures were noted as the correctly detected, the undetected and the misclassified as rice, respectively, and 81.9% and 18.0% of rice plants in the pictures were marked as the correctly detected and the misclassified as weed, respectively.
