  • The prediction of externally visible characteristics from DNA has been studied for forensic genetics over the last few years. Externally visible characteristics include hair, skin, and eye color, height, and facial morphology, which have high heritability. Recent studies using genome-wide association analysis have identified genes and variations that correlate with human visible phenotypes and developed phenotype prediction programs. However, most prediction models were constructed and validated based on genotype and phenotype information on Europeans. Therefore, we need to validate prediction models in diverse ethnic populations. In this study, we selected potentially useful variations for forensic science that are associated with hair and eye color, iris pattern, and facial morphology, based on previous studies, and analyzed their frequencies in 1,920 Koreans. Among 20 single nucleotide polymorphisms (SNPs), 10 SNPs were polymorphic, 6 SNPs were very rare (minor allele frequency < 0.005), and 4 SNPs were monomorphic in the Korean population. Even though the usability of these SNPs should be verified by an association study in Koreans, this study provides 10 potential SNP markers for forensic science for externally visible characteristics in the Korean population.

  • This study aims to investigate whether there is intensionally changing eye - gaze on the cafe space images with floor finishing materials. In the Yarbus' experiment, he argued that changing information that an observer is asked to obtain from an image changes pattern of eye movements. Based on the scan path evidence, this research have questions as (1) the difference of visual attention on finishing floor material stimulus, (2) visual attention of initial activity time and type of movement paths on AOIs, and (3) visual relation floor area with another AOIs. Eye movements were recorded with the SMI REDn Scientific, which sampled eye position at 30Hz and lasted 2 minutes(120s). Although viewing was binocular, only the right eye was tracked. Of the 66 observers(mean age 22 years, standard deviation: ${\pm}1.82$) who participated in the experiment done by the four point calibration and validation procedures at the beginning tasks. Analyzing qualitative data from the number of fixation and duration on AOIs divided into four parts (AOI I-Floor, AOI II-Wall, AOI III-Ceiling, and AOI IV-Counter) in the stimulus. The results from this experiment analyzed as follows. First, it was significant in the difference of the average number of AOIs fixation times observed for the spatial image using the wood tile flooring material and the polishing tile. The wood tile flooring of stimulus had higher fixation number on AOI-II, AOI-III, and AOI-IV than the polishing tile. On seeing AOI-I was higher attention in the polishing tile stimulus. Second, the observers examined AOI-II intensively in both stimuli. However, the visual intensity was also followed by on the AOI-IV and AOI-I in the wood tile flooring stimulus, and on AOI-I, AO-IV in the polishing tile. Third, visual attention data on each AOIs have divided into the time range of "5 sec" for both images. In the wood tile stimulus, the horizontal movement path followed by AOI-II, AOI-IV, and AOI-II. In the polished tile stimulus, the movement path followed by moving vertically to AOI-II, AOI-I, and AOI-II. This study approached meaningfully and found out the characteristics of visual attention, according to the different intentions of visual attention, the relationship pathways of visual mechanism appeared and also activated by eye-tracking experiments.

  • Background : Eye diseases refer to a wide range of disconveniences from conjunctivitis, pterygium, glaucoma to even blindness. Acupuncture has been widely used in Korea throughout the history and provides an efficient method in the treatment of them. Objectives : Establish a distinctive and efficient acupuncture method for the treatment of eye diseases based in literature research. Method : We reviewed four Korean medical literature, "Guide to Swollen Sore Treatment[治腫指南]", "Treasured Mirror of Eastern Medicine[東醫寶鑑]", "Experiential Prescriptions of Acupuncture and Moxibustion[鍼灸經驗方]", and "Essential Rhymes on Acupuncture and Moxibustion by Master Saam[舍岩鍼法]", and analyzed the therapeutic characteristics in the treatment of eye diseases. Result : 1. According to "Guide to Swollen Sore Treatment[治腫指南]", various methods were applied in the treatment of eye diseases. We can cite salt water washing method after needling, pricking bloodletting method using three-edged needle, surgery method using bent needle and lance needle, or sore treatment using sliced bean-curd and ground Aristolochiae Fructus among others. Acupuncture points like GV20[百會], BL1[睛明], EX-HN5[太陽], GB20[風池], GV24[神庭], GB1[瞳子髎], and GB15[臨泣] were mostly needled. 2. In "Treasured Mirror of Eastern Medicine[東醫寶鑑]", pricking bloodletting method were most frequently used in comparison to single acupuncture or moxibustion methods. Applied points were GV20[百會], BL1[睛明], LI4[合谷], EX-HN5[太陽], GB37[光明], BL18[肝兪], GB20[風池], BL2[攢竹], GB1[瞳子髎], and ST36[三里]. Also selections of adjacent points were considered important. 3. In respect to treatment methods "Experiential Prescriptions of Acupuncture and Moxibustion [鍼灸經驗方]" has some similarity to "Treasured Mirror of Eastern Medicine[東醫寶鑑]" as pricking bloodletting method were mostly used. Also focused on normal Qi flow through meridian. Points like BL18[肝兪], BL1[睛明], LU5[尺澤], EX-HN5[太陽], LI4[合谷] were used. 4. "Essential Rhymes on Acupuncture and Moxibustion by Master Saam[校勘舍岩道人鍼法]" considered visceral pattern identification method fundamental in the diagnosis and treatment of eye diseases. Specifically, Liver, Heart, Stomach, Lung, Kidney identification methods are presented. Combined both corresponding and connecting meridians supplementation and draining methods according to mother-child relation. Also Saam master's own experiential prescriptions are noted. Conclusions : After previous study on stroke, we could also find various efficient methods according to eye diseases, through literature research of korean medical classics. This study will concurrently result in establishing distinctive therapeutic method characteristic of Korea.

  • Obstructive sleep apnea syndrome (OSAS) is defined by sleep apnea with decreased oxygen saturation, excessive snoring with daytime sleepiness, and frequent awakening during the night time sleep. The present study was performed to investigate how apnea-hypopnea, that possibly causes breathing disturbance during sleep, can affect sleep pattern in patients with OSAS. We included 115 patients (92 men, 23 women) who underwent a polysomnography from January 2006 to May 2007. As the frequency of sleep apnea-hypopnea increases, the proportion of non-rapid eye movement (REM) sleep (p<0.001), and stage I sleep (p<0.001) increased, while that of stage II sleep (p<0.001), stage III and IV sleep (p<0.01), and REM sleep (p<0.05) decreased. Furthermore, sleep apnea-hypopnea was closely correlated with REM sleep (r=0.314, p<0.001), stage I sleep (r=0.719, p<0.001), stage II sleep (p=-0.342, p<0.05), stage III and IV sleep (r=-0.414, p<0.001), and REM sleep (r=-0.342, p<0.05). Stage I sleep could account for the 51% of the variance of apnea-hyponea. Our study shows sleep apnea-hypopnea affects sleep pattern in pattern with OSAS significantly, and the change of stage I sleep is the most important factor in estimating the disturbance of sleep pattern.

  • This study will explore the application of the Korean alphabet 'Hangul' and its calligraphy on fashion design. Hangul is well known for its great formative characteristics. Its calligraphy has unique features that express the implicative meaning of the Korean language while simultaneously displays beautiful shapes that draw the viewer's eye. When Hangul calligraphy is applied on the pattern design, it can be an excellent opportunity to demonstrate the visual beauty of Hangul. The purpose of this study is to develop the pattern designs that utilize the Hangul calligraphy and apply them in various fields of fashion. The detailed concepts of this study are as follows. First, the theoretical concepts and characteristics of both Hangul calligraphy and pattern design will be understood. Second, the aesthetic characteristics of calligraphy will be drawn by case analysis on the artworks of famous calligraphers such as Kim Jong-geon, Kang Byeong-in, Lee Sang-hyeon, Lee Gyu-bok and other representative calligraphers who design the beauty of Korean calligraphy by handwriting and brush-writing. The obtained results will be used to explore the desirable direction of fashion design. Third, eight pattern motif fashion works that utilize Hangul calligraphy in accordance with the arrangement of different characteristics of fashion design will be presented.

  • Presses are very used in industrial and commercial companies and are often the source of serious accidents occurring during operation. Most of accidents are due to inadequate design of the press machine. This paper presented an experiment which examined eye movement characteristics of the operators in the press operation. Continuous recordings of eye movements were made on five subjects in press operation. It was observed that the subjects stared longer at the die and did not stare at the switch. The eyemovemen patterns per cycle of the subjects were mostly identified as material container $\rightarrow$ die pattern type. The results could be used as basic data to establish a design guideline when manufacturer made the press machine.

  • In this paper, we propose a novel method that can detect face region effectively with fuzzy theory and neural network We make fuzzy rules and membership functions to describe the face color. In this algorithm, we use a perceptually uniform color space to increase the accuracy and stableness of the nonlinear color information. We use this model to extract the face candidate, and then scan it with the pre-built sliding window by using a neural network-based pattern-matching method to find eye. A neural network examines small windows of face candidate, and decides whether each window contains eye. We can standardize the face candidate geometrically with detected eyes.

  • A basic study on the lifting lug design has performed through the rational and systematic process. In order to evaluate the proper design-load distribution around lug eye investigation of contact force between lifting lug and shackle pin is performed using non-linear parametric analysis idealized by gap element models. Gap element modeling and nonlinear analysis procedures are illustrated and discussed based on MSC/NASTRAN. Some analysis and design guides are suggested through the consideration of several important effects such as stress distribution pattern, circumferential contact force distribution along the lug eye face, loading share rate between lug main plate and doubler, effect of loading direction, relation between applied force and deflection and size effect of shackle pin radius. Additionally optimum design studies are performed and general trends according to the variation of design parameters are suggested.
