( Hyewon Hyewon Park ),( Jung Hee Yang ) 한국패션비즈니스학회 2012 패션 비즈니스 Vol.16 No.3

This study proposed a color scheme that is harmonious with the working environment of industrial sites using Birren`s color harmony theory for color planning. To apply the Birren`s color harmony theory to working clothes, the basic colors were chosen, and six of the eight harmony formulas of Birren excluding achromatic colors (white + grey + black) and solid color harmony (solid colors + white + black) were used to form a palette for each case. For the basic colors, the color chips of four dominant colors (yellow-green, sky-blue, blue, and violet), which were chosen from a field survey for preferences in the first step, and the production of materials in the second step were collected through the PANTONE color chips. The selected color chips were PANTONE 13-0550 TPX, PANTONE 15-4105 TPX, PANTONE 18-3949 TPX, and PANTONE 19-3720 TPX. These color chips were scanned and their RGB values were extracted through Photoshop CS. Then the colors were arranged in accordance with the Birren`s color harmony formulas (Color+Tint+White, Color+Shade+Black, Tint+Tone+Shade, Shade+Tone+Black, Shade+Tone+White, and Tint+Shade+Tone+Gray). In addition, the proposed palette color schemes were applied through Birren`s color harmony formulas using Texpro V 10.1 textile to the schematization of working clothes that were designed in the previous study. Palette formation in line with Birren`s color harmony formulas provided scientific color arrangement results. Visually presenting the color scheme of working clothes will help the color selection of working clothes in tune with the circumstances of industrial sites.

Appearance of a device that has a form of tablet PC and characteristic of mobility is newly changing experience and behavior of humans who used to deliver and spend messages through various medium. This means a paradigm of new book that mixes a story structure of a book that can deliver information when or where transcending space time, entertainment factors of TV, and attribute of network and hypermedia that the web has had appeared. Moreover, use of touch interface, which is intuitive control method, and various sensors changed a communication form of focusing on text and image to the media that includes movement according to control of users and interaction with the device. Therefore, this study tried to find out change in way of reading in a space called book through change process of reading path that has flexible and dynamic structure in historical consideration of interface and linear, static structure. It was found that interface of papyrus scroll had made linear reading path and interface of codex page had made reading path that has fixity and integrity. And also the relationship of this interface and reading path had influence on reading path of hyperlinks of web, mobile and even 'Wired magazine' of 'iPad' that includes other media actively, and the reason it is changed to hypermedia reading path that includes interaction with users was affected from the precious interface. Advancing from cognizing new experience of reading, the study tried to help on writing that is suitable for new media and interaction method based on understanding of characteristics of device and text. This study is considered to have a significance in suggesting new direction of a book that has characteristics of entertainment, which can maximize fun for users or books in educational and practical fields that can let obtaining of information efficiently through synaesthetic experience.

Irritability is a heritable core mental trait associated with several psychiatric illnesses. However, the genomic basis of irritability is unclear. Therefore, this study aimed to 1) identify the genetic variants associated with irritability and investigate the associated biological pathways, genes, and tissues as well as single-nucleotide polymorphism (SNP)-based heritability; 2) explore the relationships between irritability and various traits, including psychiatric disorders; and 3) identify additional and shared genetic variants for irritability and psychiatric disorders. We conducted a genome-wide association study (GWAS) using 379,506 European samples (105,975 cases and 273,531 controls) from the UK Biobank. We utilized various post-GWAS analyses, including linkage disequilibrium score regression, the bivariate causal mixture model (MiXeR), and conditional and conjunctional false discovery rate approaches. This GWAS identified 15 independent loci associated with irritability; the total SNP heritability estimate was 4.19%. Genetic correlations with psychiatric disorders were most pronounced for major depressive disorder (MDD) and bipolar II disorder (BD II). MiXeR analysis revealed polygenic overlap with schizophrenia (SCZ), bipolar I disorder (BD I), and MDD. Conditional false discovery rate analyses identified additional loci associated with SCZ (number [n] of additional SNPs = 105), BD I (n = 54), MDD (n = 107), and irritability (n = 157). Conjunctional false discovery rate analyses identified 85, 41, and 198 shared loci between irritability and SCZ, BD I, and MDD, respectively. Multiple genetic loci were associated with irritability and three main psychiatric disorders. Given that irritability is a cross-disorder trait, these findings may help to elucidate the genomics of psychiatric disorders.

This study investigated effects of individual variables on speaking proficiency development of short-term study-abroad students in Korea. Forty-one learners were asked to complete a story recall task after watching a short Korean animation at the beginning and the end of the semester, and their responses were analyzed for syntactic development according to the CAF(Complexity, Accuracy, Fluency). This study also used self-reporting questionnaires to measure intercultural sensitivity, personality, and social networks. Results showed that although many participants achieved L2 gains in speaking proficiency on the whole during their study abroad, speaking complexity was meaningfully improved(p=.025) Specific subcategories of learners’variables that gave effect on improvement of speaking are as follows: I) Openness of personality had the most significant influence on improvement of speaking complexity(.589), ii) dispersion of social networks also had an effect on speaking complexity(.327), implying that the much interaction with Korean native speakers enhances Korean language learners‘ speaking complexity.

최근 국내 방송 업계에서 프로그램 제작 아이디어를 쉽고 빠르게 획득하기 위하여, 방송 프로그램 포맷을 수입하여 프로그램을 제작하여 방영하고 있다. 방송 산업에서 포맷이란 일련의 시리즈물 프로그램에서 각각의 에피소드를 구성하는 가변의 요소들이 시리즈물 내내 변화지 않고 꾸준히 유지되는 프로그램 요소들의 집합을 의미하는 개념으로 사용되고 있다. 예컨대 국내에 방영되고 있는 퀴즈 프로그램인 1:100의 경우, 해외에서 포맷을 수입하여 국내에서 제작한 대표적인 사례라고 할 수 있다. 즉, 포맷이란 프로그램의 독창적인 아이디어와 구성요소를 내포하고 있는 프로그램 기획안과 유사하지만, 더 구체적인 제작 설명서에 가깝다고 할 수 있다. 본 연구는 방송 프로그램의 포맷 창작을 위하여 다수의 사용자가 창의적인 아이디어를 도출하고 확장하여, 이를 포맷 제작에 적합하게 재구성할 수 있도록 하는 시스템을 웹을 기반으로 구현하고, 이를 방송 프로그램 전문가들이 활용할 수 있도록 하고자 하는데 그 목적이 있다. Recently broadcasting production companies have imported a number of broadcast program formats to get ideas quickly and easily. The term format in broadcasting industry is defined as a paper form which includes principal elements throughout each episode of the series in a program to keep consistency. In case of the quiz program titled 1:100 which is being aired in Korea, the domestic company imported the format and produced to broadcast in Korea. In other words, a format includes components of the inherent creative ideas and proposals needed in production a program. The study proposed a web based collaborative system that many users create the format for the broadcast program together. the system is constructed to combine creative ideas to making them a format. Also, production experts will take advantage of the system.

Background: Global Lung Function Initiative (GLI)-2012 reference equation is currently suggested for interpretation of spirometry results and a new local reference equation has been developed in South Korea. However, lung function profiles according to the different reference equations and their clinical relevance have not been identified in chronic obstructive pulmonary disease (COPD) patients. Methods: Our cross-sectional study evaluated Choi’s, Korean National Health and National Examination Survey (KNHANES)-VI, and GLI-2012 reference equations. We estimated the percentages of predictive forced expiratory volume in one second (FEV1) and airflow limitation severity according to reference equations and analyzed their associations with patient reported outcomes (PROs): COPD assessment test (CAT) score, St. George's Respiratory Questionnaire for COPD patients (SGRQ-C) score, and six minute walk distance (6MWD). Results: In the eligible 2,180 COPD patients, lower predicted values of FEV1 and forced vital capacity (FVC) were found in GLI-2012 compared to Choi's and KNHANES-VI equations. GLI-2012 equation resulted in a lower proportion of patients being classified as FEV1 < 80% or FVC < 80% compared to the other equations. However, the Z-scores of FEV1 and FVC were similar between the KNHANES-VI and GLI-2012 equations. Three reference equations exhibited significant associations between FEV1 (%) and patient-reported outcomes (CAT score, SGRQ-C score, and 6MWD). Conclusion: GLI-2012 reference equation may not accurately reflect FEV1 (%) in the Korean population, but the Z-score using GLI-2012 equation can be a viable option for assessing FEV1 and airflow limitation in COPD patients. Similar to the other two equations, the GLI-2012 equation demonstrated significant associations with PROs.

ORiginal Article : An Inverse Relationship between the Expression of the Gastric Tumor Suppressor RUNX3 and Infection with Helicobacter pylori in Gastric Epithelial Dysplasia

Background/Aims: This study was performed to determine the association between RUNX3 expression and Helicobacter pylori infection in premalignant gastric lesions. Methods: We examined 107 patients with gastric epithelial dysplasia who had undergone endoscopic mucosal resection or submuco-sal dissection. All tissue samples were evaluated by RUNX3 staining and subclassified by immunophenotype. H. pylori infection in dysplastic lesions and the normal surrounding tissue was examined by silver staining, and cagA status was assessed by polymerase chain reaction. Results: The loss of RUNX3 expression was observed in 62 cases (57.9%), and an association with H. pylori infection was found in 54 cases (50.5%). The infection rate with the cagA-positive H. pylori strain was 63.0%. In RUNX3-negative lesions, the rate of H. pylori infection (p=0.03) and the frequency of category 4 le-sions (according to the revised Vienna classification) were high (p=0.02). In addition, the gastric mucin phenotype was predominant. In RUNX3-negative category 4 lesions, the rate of cagA-positive H. pylori infection rate was high but not significantly increased (p=0.08). Conclusions: Infection with H. pylori is associated with inactivation of RUNX3 in early gastric carcinogenesis. This mechanism was prominent in gastric cancer with a gastric mucin phenotype.
