The purpose of the present study is to analyse characteristics of the background noise for the broadband seismic stations in KMA. It is well known that the background noise arises continuously from long period microseism, sea waves, minute changes of atmospheric pressure, seasonal temperature change of the ground surface, culture activities, and etc. The background noise shows spatial and temporal changes and it has various characteristics such as its spectral amplitudes in frequency domain are not constant Such the background noise gives considerable influences on the quality of seismic record. To investigate annual variations, the background noise was separated into high frequency components of above 1Hz More larger average amplitude is found in winter than other seasons. The average amplitude for 12 seismic stations are compared. It is known that the background noise is considerably larger in stations located in island region such as Jeju, Ulleungdo, and Bagryeongdo seismic stations. However the noise is relatively small in inland stations such as Chuncheon, Chungju and Uljin seismic stations.

This study examined how child care teachers' background characteristics, self-efficacy and job stress relate to their job satisfaction. Participants were 400 child care teachers in Seoul and Gyeonggi, Korea. Structural equation models were developed based on the authors' hypothesized model, which proposed that teachers' self-efficacy and job stress have a mediating effect in the relationship between teachers' background characteristics and job satisfaction. The results revealed that career directly influenced on self-efficacy and job stress but had no direct effect on job satisfaction. Education level was found to have a direct effect on job stress but had no direct effect on self-efficacy and job satisfaction. Teachers' self-efficacy affected job stress and job satisfaction and job stress affected job satisfaction. Furthermore, self-efficacy mediated the effects of career on job stress and job satisfaction. Additionally, job stress mediated the effects of education level and self-efficacy on job satisfaction. These results suggested that teachers' self-efficacy and job stress were key predictors and mediating variables in the relationship between background characteristics and job satisfaction.

As video equipments such as CCTV are used for various purposes in fields of society, digital video data processing technology such as automatic motion detection is essential. In this paper, we proposed and implemented a more stable and accurate motion detection system based on background subtraction technique. We could improve the accuracy and stability of motion detection over existing methods by efficiently processing color information of digital image data. We divided the procedure of color information processing into each components of color information : brightness component, color component of color information and merge them. We can process each component's characteristics with maximum consideration. Our color information processing provides more efficient color information in motion detection than the existing methods. We improved the success rate of motion detection by our background update process that analyzed the characteristics of the moving background in the natural environment and reflected it to the background image.

The ramp type bias voltage applied to the common electrode during a reset-period is newly proposed to lower the background luminance and to improve the address discharge characteristics in AC-PDP. The positive ramp bias voltage is applied during the ramp-up period, whereas the negative ramp bias voltage is applied during the ramp-down period. The effects of the voltage slopes in both the positive and negative ramp bias voltages on the background luminance and address voltage characteristics are examined intensively. It is observed that the optimized positive and negative ramp bias voltages applied to the common electrode during the ramp-period can lower the background luminance and also enhance the address discharge characteristics of the AC-PDP.

As personal data breach reared up as a problem domestically and globally, organizations appointing chief privacy officers (CPOs) are increasing. Related Korean laws, 'Personal Data Protection Act' and 'the Act on Promotion of Information and Communication Network Utilization and Information Protection, etc.' require personal data processing organizations to appoint CPOs. Research on the characteristics and role of CPO is called for because of the importance of CPO being emphasized. There are many researches on top management's role and their impact on organizational performance using the Upper Echelon theory. This study investigates what influence the characteristics of CPO gives on the organizational privacy performance. CPO's definition varies depending on industry, organization size, required responsibility and power. This study defines CPO as 'a person who takes responsibility for all the duties on handling the organization's privacy,' This research assumes that CPO characteristics such as role, personality and background knowledge have an influence on the organizational privacy performance. This study applies the part relevant to the upper echelon's characteristics and performance of the executives (CEOs, CIOs etc.) for CPO. First, following Mintzberg and other managerial role classification, information, strategic, and diplomacy roles are defined as the role of CPO. Second, the "Big Five" taxonomy on individual's personality was suggested in 1990. Among these five personalities, extraversion and conscientiousness are drawn as the personality characteristics of CPO. Third, advance study suggests complex knowledge of technology, law and business is necessary for CPO. Technical, legal, and business background knowledge are drawn as the background knowledge of CPO. To test this model empirically, 120 samples of data collected from CPOs of domestic organizations are used. Factor analysis is carried out and convergent validity and discriminant validity were verified using SPSS and Smart PLS, and the causal relationships between the CPO's role, personality, background knowledge and the organizational privacy performance are analyzed as well. The result of the analysis shows that CPO's diplomacy role and strategic role have significant impacts on organizational privacy performance. This reveals that CPO's active communication with other organizations is needed. Differentiated privacy policy or strategy of organizations is also important. Legal background knowledge and technical background knowledge were also found to be significant determinants to organizational privacy performance. In addition, CPOs conscientiousness has a positive impact on organizational privacy performance. The practical implication of this study is as follows: First, the research can be a yardstick for judgment when companies select CPOs and vest authority in them. Second, not only companies but also CPOs can judge what ability they should concentrate on for development of their career relevant to their job through results of this research. Cultural social value, citizen's consensus on the right to privacy, expected CPO's role will change in process of time. In future study, long-term time-series analysis based research can reveal these changes and can also offer practical implications for government and private organization's policy making on information privacy.

Background in a novel is most important elements with characters and events, and means time, place and situation that characters appeared. Among the background, spatial background can help conveys topic of a novel. So, it may be helpful for choosing a novel that readers want to read. In this paper, we are targeting Korean historical novels. In case of English text, It can be recognize spatial background easily because it use upper and lower case and words used with the spatial information such as Bank, University and City. But, in case Korean text, it is difficult to recognize that spatial background because there is few information about usage of letter. In the previous studies, they use machine learning or dictionaries and rules to recognize about spatial information in text such as news and text messages. In this paper, we build a nation dictionaries that refer to information such as 'Korean history' and 'Google maps.' We Also propose a method for recognizing spatial background based on patterns of postposition in Korean sentences comparing to previous works. We are grasp using of postposition with spatial background because Korean characteristics. And we propose a method based on result of morpheme analyze and frequency in a novel text for raising accuracy about recognizing spatial background. The recognized spatial background can help readers to grasp the atmosphere of a novel and to understand the events and atmosphere through recognition of the spatial background of the scene that characters appeared.

Based on the background of the times and theoretical background that influenced the formation of the works of Charles Rennie Mackintosh, one of representative architects of Art Nouveau, this study examined the formative characteristics of furniture design by period. In addition, his influences on the modern furniture design were also reviewed. In the latter half of the 19th century, due to Arts and Crafts Movement, the popularity of Art Nouveau was not high in England and due to conservative and traditional culture, Mackintosh had difficult time to display his ability in England. On the other hand, because Glasgow, one of industrial cities located in the center of Scotland where he had grown was an open and modern city, Mackintosh could win international fame in architecture and furniture design thanks to the atmosphere. Furthermore, it is found from the formative characteristics of his works that Historicism, Arts and Crafts Movement and Japanese culture and the influences of Continent became his theoretical background. His works creatively combined the noble design of Scotland and Art Nouveau to be considered a simple and pure style with a straight tendency and his working period can be divided into Beginning, Middle and Last Period according to the formative characteristics of furniture design. His constituting principle that decorated the structure influenced the Wien Secession's activities to form Wiener Werkstaette and this finally became the important background to develop to 'Modernism Design' through Art Deco and Bauhaus.

The purpose of this study was to identify the variables which could characteristics the New Young Generation (NYG), to investigate the relationship between level of NYG characteristics and information searching related to underwear purchasing, and the differences level of the NYG characteristics according to demographic variables (sex, grade, major), and examine the casual relationships of demographic variables (sex, place of growing background, parent's education) and level of the NYG characteristics on information searching related to underwear purchasing. The subjects were 723 college students (female = 324, male=398) living in Seoul and Kyuggi were participated in this study. The NYG is limited to person who born after 1970's. The result of this study were as follows; 1. Five factors of New Young Generation oriented characteristics were identified; F.1 'Info-telecommunication(Info-Telecom)'; F.2 'Family and Marriage'; F.3 'Consumption pattern'; FA 'Self-centered (Individualism)'; F.5 Work/Career oriented. 2. The relationship between the NYG characteristics and information search in underwear purchasing were significanted. 3. In demographic variables, gender, grade, and major were partially significant differences. 4. In male students, the result of the casual relationship between demographic variables with NYG characteristics and the level of the NYG in underwear purchasing showed that grade, background of grownplace, level of parent's education were significanted the high level of info-telecom factor associated with higher grade, city-grown, higher level of parent's education. In conclusion, the result showed that the level of NYG characteristics was significant to male students and specially for grade older students. The background of parent's education level was the another important variables to predicting the NYG characteristics. Finally the higher the NYG characteristics, the more information search in underwear purchasing.
