Knowledge space theory is a theory that provides a guidelines for human learners' possible education decisions and has been used in various educational environment. However, traditional methodologies using the knowledge space theory have always depended on handwork system and it is necessary to learn programming language such as Visual Basic and R, causing time consuming situations. In order to overcome those issues on the environment of education we propose a new Knowledge Structure Analysis System that not just analyzes learners' knowledge structures automatically but to provide critical learning path for the learners based on knowledge space theory. Proposed system is implemented by using rApache generating critical learning path computing Chi-square value. This provides an automatic way of analyzing knowledge structure in learners' knowledge space and shows systematic reviews for the knowledge space.

Director Choi Donghoon is the most famous director in Korea as a box office successor, especially (2102) has gained No. 1 box office attraction in Korean film history. However some critics have criticised the works of Dr. Choi because of their plebeianness. This paper focused on the reason of interaction with audiences through the theory of carnival of Mikhail M. Bakhtin. Because the theory of carnival is not only the adapted method to account for the power of popular culture to M. Baktin but also the useful method to understand the keys of interaction of Dr. Choi's films. It's not difficult to find the esthetic elements of carnival theory example for 'dethronement & coronation', 'overturn & ridicule', 'image of feast', 'language of square' in the films of Choi which are The Big Swindle(2004), Tazza: The High Rollers(2006), Woochi(2009), The Thieves(2012). Therefore this paper has endeavored that the box office attraction and success of communication with audiences is due to the realistic attitude and social reflection of Choi's films.

This study were conducted to assess the physical growth and developmental status of infants in orphanage in order to provide an empirical data. The subjects for this study were 104 infants and toddlers who were reared in an orphanage in D Metropolitan city. The instrument used for this study were anthropometric assessment and DDST for normative data of development. Data has been collected from September 1st, 1998 to August 31st, 2000 and were analyzed using SPSS/PC(Version 10.0) with frequency, mean, standard deviation, ANOVA and Chi-square test. The results of this study were as follows; 1. 30.8% of infants in orphanage had abnormal weight, 26.9% had abnormal length, and 22.1% had abnormal head circumference and most of them were distributed below 50 percentile of growth chart. 2. 53.8% of infants in orphanage had normal, 27.9% had qustionable, and 18.3% had abnormal developmental screening test results, especially, 31.5% of infants in orphanage ages 3 to 5 years had abnormal developmental screening test results, according to the Denver Developmental Screening Test(DDST). There was a significant developmental delay noted in the language and fine motor-adaptive sector. 3. It is anticipated that developmental delays would increase in severity by older the mean age of orphanage infants and longer the time being raised in orphanage. It would be concluded that the physical growth and developmental status of orphaned infants were very vulnerable and serious and it is suggested that there needed an effective intervention strategies to promote growth and development of infants in orphanage.

Background: The work force in industries are at risk of developing unduly high rates of health and behaviour related problems including abuse of alcohol, betel nut and cigarette (alcohol, betel nut and cigarette consumption). This study describes the relationships between alcohol, betel nut and cigarette consumption and health promoting behaviour among industrial workers. Materials and Methods: A cross sectional survey was conducted on workers in various industries of Ghaziabad city with concerned authority permission. A sample size of 732 workers was calculated based on pilot study. Through Simple random sampling 732 workers in 20 to 50 years age group with informed consent were interviewed through structured, pretested, validated questionnaire in vernacular language by one calibrated investigator. Data on socio demography, alcohol, betel nut and cigarette consumption pattern and health behaviour were collected. The association between health promoting behaviour and alcohol, betel nut and cigarette consumption was analysed by Logistic regression and Chi-square test through SPSS 16 at p<0.05 and 95%CI as significant. Results: Total prevalence of alcohol, betel nut and cigarette consumption in study population was 88%. The prevalence of individual alcohol, betel nut and cigarette consumption were 82%, 68% and 79% respectively. Combined alcohol, betel nut and cigarette prevalence in study population was 58%. Alcohol and cigarette users were significantly higher (p<0.001) in 30 to 40 years age group with lower level of education having poor attitude towards health promoting behaviour, poor oral hygiene practices and rare indulgence in regular physical exercise. Conclusions: This study stimulate further research on exploring methods to prevent initiation of health risk behaviour and promote healthy behaviour with cessation help for the current alcohol, betel nut and cigarette users.

This paper presents a low-power, low-complexity design and implementation results of a high speed multiple-input multiple-output orthogonal frequency division multiplexing (MIMO-OFDM) wireless LAN (WLAN) baseband processor. The proposed processor is composed of the physical layer convergence procedure (PLCP) processor and physical medium dependent (PMD) processor, which have been optimized to have low-power and reduced-complexity architecture. It was designed in a hardware description language (HDL) and synthesized to gate-level circuits using 0.18um CMOS standard cell library. As a result, the proposed TX-PLCP processor reduced the power consumption by as much as 81% over the bit-level operation architecture. Also, the proposed MIMO symbol detector reduced the hardware complexity by 18% over the conventional SQRD-based architecture with division circuits and square root operations.

The study was focused on surveying the cultural identity and the origin of T-shirts, and examining their functions. Six cities were selected to categorize the design motifs of cultural identity appearing in the design of contemporary T-shirts. These cities include a city in France, United Kingdom, Italy, United States and Japan where collections are currently presented at, and also a city in China that has shown a high economic growth as one of the most popular sightseeing cities. Cultural identity was presented in the T-shirts that were examined in this study through diversified design motifs. Motifs used in T-shirt designs to reflect cultural identity included national flags, notable places, letters, names of geographic places, and individuals. A national flag is a motif that signifies national identity and it was used in the front of T-shirts as it is or was just partially used. Also, many world-renowned structures or architectural buildings were applied to T-shirt design. Noted places such as the White House, the Statue of Liberty in the U.S., Tienanmen Square in China and the Eiffel Tower in France were used. The unique characters of language, such as Hangeul in Korea were used as design elements to reflect the structural characteristics of letters. Names of geographic places were used as design elements through the disclosure of the name of a symbolic city or a tourist site in each country. In terms of figures, not only the historical figures or celebrities from each country were used, but the image of bodies and faces that represent each culture were used as well. In addition, this study was used to develop T-shirt designs that reveal the cultural identity of Korea.

Lately, Digital Photogrammetry has been increasingly applied to various hightech industries and becomes one of more interesting focuses of study than ever. Thus, this study aims to develop a Road Horizontal Alignment Information System by means of digital photogrammetry. Data acquired from digital photographic techniques were processed using Delphi, an object oriented programming language to develop a computer aided program, that allows us to build the information on Road Horizontal Alignment(Beginning Point of Curve, Ending Point of Curve, Radius, Intersection Point). The developed program could maximize visualization for better analysis compared with traditional programs because it utilizes many image data. Comparing with data from traditional horizontal alignment extraction programs based on the principle of least square method, the data acquired by Horizontal Alignment Information and kinematic GPS showed out of the developed road information systems the improved accuracy of IP value up to about 2m in the direction of X, Y axes, where the accuracy of curve radius(R) becomes enhanced up to about 2.5 m.

Objectives: About for twenty years, immigrant women in South Korea have steadily increased due to economic growth and industrialization. According to previous studies in terms of immigrants, subjective socio-economic status(SES) as well as objective SES such as income, occupation and level of education predict health outcomes. The purpose of this study was to examine association between subjective social status and perceived health among immigrant women. Methods: We analyzed 12,531 participants from the 2012 National Survey of Multicultural Families. Study variables included subjective SES in Korea, subjective SES in community and perceived health. Control variables were age, household income, employment, education, marital status, ethnicity, language proficiency. For this study, descriptive analysis, Chi-square test, and multivariate logistic regression analysis were performed. Results: Among immigrant women, after adjusting for control variables, level of education in community was not associated with perceived health. Otherwise, subjective social status in Korea(low subjective social status reference group vs high subjective status : OR 2.056) was associated with perceived health. Conclusions: Immigrant women in Korea would be culturally affected by inherent characteristic rather than social economic status. Through this study, in order to improve health inequality among immigrant women, we should consider developing social supports and networks.

PURPOSE. This study aimed to compare the accuracy (trueness and precision) of interim crowns fabricated using DLP (digital light processing) according to post-curing time. MATERIALS AND METHODS. A virtual stone study die of the upper right first molar was created using a dental laboratory scanner. After designing interim crowns on the virtual study die and saving them as Standard Triangulated Language files, 30 interim crowns were fabricated using a DLP-type 3D printer. Additively manufactured interim crowns were post-cured using three different time conditions-10-minute post-curing interim crown (10-MPCI), 20-minute post-curing interim crown (20-MPCI), and 30-minute post-curing interim crown (30-MPCI) (n = 10 per group). The scan data of the external and intaglio surfaces were overlapped with reference crown data, and trueness was measured using the best-fit alignment method. In the external and intaglio surface groups (n = 45 per group), precision was measured using a combination formula exclusive to scan data (10C2). Significant differences in accuracy (trueness and precision) data were analyzed using the Kruskal-Wallis H test, and post hoc analysis was performed using the Mann-Whitney U test with Bonferroni correction (α=.05). RESULTS. In the 10-MPCI, 20-MPCI, and 30-MPCI groups, there was a statistically significant difference in the accuracy of the external and intaglio surfaces (P<.05). On the external and intaglio surfaces, the root mean square (RMS) values of trueness and precision were the lowest in the 10-MPCI group. CONCLUSION. Interim crowns with 10-minute post-curing showed high accuracy.
