Due to the explosive growth of the internet, terminology like "information society" and "virtual space" is frequently used, but often in a confusing manner. Some Social theorists and many people are fascinated by "information" and "media" as key characteristics of the contemporary world and rely on the unproven opinion that "Knowledge is a source of value and information moves the world". In this regard, Boudllian defines contemporary culture as a culture of signs and insists that we are surrounded by signs and forms of meaning. There isn't anything behind the signs but signs only exsist, so we cannot escaped from its inauthenticity and consider it improper to insist on it. If people can understand that signs are just simulation of reality, that would be alright. But in fact anything cannot be alright.In this matter Boudllian's conclusion is that we produce images in bulk which are not worthy seeing. Today we reach the conclusion that most images are the letter(character) image itself which shows nothing special.Consequently, this kind of world is a postmodern-world that seems meaningless but has signs to experience and enjoy, many examples of which are shown in the media, such as the internet. We can get to the conclusion that the audience neither sees nor hears anything, but they just can experience many interesting things which characterize the present age. The purpose of this research is to help you to understand current design philosophy and the direction of media while considering both a positive social phenomenon about the new design paradigm of information and media, as well as critical thinking about it.

As all other cultures do, in the background of color of costume, view of life or spirit are contained in the nature or environment that the people lived in are applied. Marring is the ceremony to be socially recognized that both of sexes are unified, assist ancestor and bear future generation. Meaning and symbolism of color are appeared in beauty and organic composition of Lee dynasty. This paper tried to dear up five colors are dean, beautiful and philosophical colors rather than awkward composition of colors through surveying character of five colors appeared in Korean traditional wedding dress that has been succeeded in present age. This paper compared Korean traditional wedding dress and "Dan-chung" of Korea, Japan and China and surveyed theoretical background of Korean traditional color to find character of color appeared in Korean traditional wedding dress. As a result, Korean traditional color is meaningful symbolic color, its origin starts in yin-yang and the live elements of the Oriental cosmogony and it is related with Taoism of Confucianism and color of "Dan-chung." Five colors of yin-yang means everything under the sun and il is the color achieving beauty of balance due to correlation when it is linked to over one color. Further, it contains nature worship and human dignity, prays happiness and gives the significance of "Buksa", meaning of expelling an evil spirit. Formative beauty praying that all creatures are harmonized while human is happy and escapes from uncertainty is the beauty pursuing mental satisfaction as well as visual satisfaction. In future, the creational and characteristic designs that can appeal to world are required through right understanding and study of the beauty of traditional culture beauty of traditional culture

A large number of man-made chemicals that have been released into the environment have the potential to disrupt the endocrine system of animals and humans. There is a critical developmental period during which sexual brain differentiation proceeds irreversibly under the influence of gonadal hormone. Recently we identified KAP3 gene expressed during the critical period of rat brain sexual differentiation. KAP3 functions as a microtubule-based motor that transports membranous organelles anterogradely in cells, including neurons. In the present study, we aimed to investigate the effect of endocrine disrupter, Dichlorodiphenyl trichloroethane (DDT), on the KAP3 gene expression during critical period of rat brain development. Maternal exposure to DDT increased the level of KAP3 mRNA in male and female fetus brains when examined on the gestational day 17 (GDl7). In postnatal day 6, DDT suppressed the expression of KAP3 gene in male and female rat brain. Also, the body weight and fertilization rate were decreased in the DDT exposured rats. These results showed that endocrine disrupter, DDT, can affect the transcriptional level of brain sexual differentiation related gene, KAP3, in the prenatal and the neonatal rat brain and that maternal exposure to endocrine disruptors may lead to a toxic response in embryonic differentiation of brain. And so KAP3 gene may be used a gene maker to analyse the molecular mechanism for toxic response in animal nerve tissues exposed to endocrine disruptors.

'Ilpum', a Korean short-grain mid-late maturing rice cultivar, was developed in 1990, more than 30 years ago. Despite its age, it has been the most widely grown cultivar in the Gyeongbuk province of South Korea for more than 25 years, making it the most important rice cultivar for the people of the Gyeongbuk province. The aim of this study was to analyze the relationship between the rice yield of "Ilpum', the main rice cultivar in the Gyeongbuk province, and climate elements in the Daegu (southern plain area) and the Andong (inland mountainous area) regions in Gyeongbuk, South Korea. The rice yield over the past five years increased by about 13% and 24%, compared to that produced in the late 1990s in Daegu and the early 2000s in the Andong region, respectively. The number of panicles per hill and the grain ripening rate significantly affected rice yield in the 'Ilpum' cultivars in the Daegu region. The faster heading was a factor in the increase in 'Ilpum' rice yield in the Andong region. The air temperature has been rising and sunshine duration has been increasing from the late 1990s to present in both regions. Rice yield was evaluated to understand the effect of climate factors. The rice yields increased owing to the long sunshine duration during the grain-filling stage in both regions. In Andong, increasing the maximum temperature during the vegetative stage increased rice yield. Rising air temperature during the reproductive stage also increased rice yield. In particular, long sunshine hours throughout the whole rice growing period increased the rice yield of this cultivar in the Andong region.

The objective of the present study was to determine the best model to describe and quantify the changes in live body weight, height at withers, height at rump, body length and chest girth of Holstein cows raised under Korean feeding conditions for 50 months. The five standard growth models namely polynomial linear regression models, regression of growth variables on the first and second-order of ages in days (model 1) and regression of growth variables on age covariates from first to the third-order (model 2) as well as non-linear models were fitted and evaluated for representing growth pattern of Holstein cows raised in Korean feeding circumstances. Nonlinear models fitted were three exponential growth curve models; Brody, Gompertz, and von Bertalanffy functional models. For this purpose, a total of 22 Holstein cows raised in Korea used in the period from April 2016 to May 2020. Each model fitted to monthly growth curve records of dairy cows by using PROC NLIN procedure in SAS program. On the basis of the results, nonlinear models showed the lower root mean square of error (RMSE) for live body weight, height at withers, height at rump, body length and chest girth (12.22, 1.95, 1.55, 4.04, 2.06) with higher correlation coefficiency (R²) values for live body weight, height at withers, height at rump, body length and chest girth (0.99, 0.99, 0.99, 1.00, 1.00). Overall, the evaluation of the different growth models indicated that the Gompertz model used in the study seemed to be the most appropriate one for standard growth of Holstein cows raised under Korean feeding system.

Immunization has been one of the most effective measures preventing from infectious diseases. However, children routine vaccination rate of Korea was 68.2% and it was not higher than expected. Korean government revised the School Health Law for every primary school children to submit the vaccination certificate record from 2005. It is quite important national Infectious disease prevention policy to keep the immunizations rate high and monitor the immunizations rate continuously. To do this, National Institute of Health introduced the National Immunization Registry(NIR) Program at 2000. Objective : The aims of this study was to evaluate the Immunization Registry program which has been implementing since 2000 at the Public Health Centers(PHC). Methods : The mail survey was done from November 2001 to January 2002. 169 (69%) Public Health Centers among 244 PHC were responded. Results : The respondents of PHC sud the Immunization Registry(IR) program had reduced the workload (18.5%). 69.2% said they inputted the immunization data into the IR program after the shots were given. 86.5% said they hadn´t checked or retrieved the children lists who had missed the scheduled immunization. Only 17.2% said the speed of internet for the R program was good. It showed that 20% of respondents hadn´t written down documents, records on immunization any more. Even there were a lot of negative results, the respondents of PHC thought that the IR program was effective. They especially agreed that the IR program could make the job accurate (81.5%), convenient (71.3%), and reduced the chances of making mistakes (71.3%), increase the service quality (78.5%). And they were well adapting the job process of the IR (79.63%). Bivariate analysis showed that the software program was the important determinants of IR success. The only Bit Computer software program has been evaluated to be less satisfactory than the Integrated (Posdata operating system + Bit software) program. Other variables, such as age, duration of present job, and location of PHC (metropolitan, small city, rural area) were not significantly related. Conclusion : It seemed that the success of NIR might depend on the software program. Because Integrated program, which has been developed from 1994, include not only the general operating and management program for PHC but also IR program. It was natural to prefer Integrated program to Bit software program. So we can suggest that it is essential for the NIR to be successful that not only the immunization software program but also hardware equipments and public health information system should be further improved.

3D GIS(Geographic Information System) processes, analyzes and presents various real-world 3D phenomena by building 3D spatial information of real-world terrain, facilities, etc., and working with visualization technique such as VR(Virtual Reality). It can be applied to such areas as urban management system, traffic information system, environment management system, disaster management system, ocean management system, etc,. In this paper, we propose video visualization technology based on 3D geographic information to provide effectively real-time information in 3D geographic information system and also present methods for establishing 3D building information data. The proposed video visualization system can provide real-time video information based on 3D geographic information by projecting real-time video stream from network video camera onto 3D geographic objects and applying texture-mapping of video frames onto terrain, facilities, etc.. In this paper, we developed sem i-automatic DBM(Digital Building Model) building technique using both aerial im age and LiDAR data for 3D Projective Texture Mapping. 3D geographic information system currently provide static visualization information and the proposed method can replace previous static visualization information with real video information. The proposed method can be used in location-based decision-making system by providing real-time visualization information, and moreover, it can be used to provide intelligent context-aware service based on geographic information.

The objective of present study was to investigate the effect of seasons on reproductive performance of Hanwoo and Holstein heifers. Heat stress in summer or cold stress in winter stress to Hanwoo and Holstein heifers may bring reproduction failure, which would pose an important economic loss, even around Daegwallyeong region located in high mountainous area. Seasonal differences in the serum levels of LH, FSH and progesterone ($P_4$) in response to environmental factors (hot and cold) out of 20 pubertal Hanwoo heifers in Daegwallyeong, Gangwon Province and 20 non-lactating Holstein heifers in Chonan city of Republic of Korea at 2-3 years of age were compared. Blood samples for hormonal analysis were from jugular vein after detection of estrus repeatedly over four seasons within four-week intervals (Spring: May to June, Summer: July to August, Autumn: October to November and Winter: January to February). In Hanwoo heifer population, averages of LH and FSH concentration in spring and in summer were greater compared to those in winter (p<0.05). LH or FSH levels tended to be greater (p=0.06) in spring and less (p=0.09) in winter compared to the levels in autumn. Only in summer, cattle seemed to show lower LH or FSH secretion (p<0.05). Similar to the results in Hanwoo heifers, the serum concentrations of LH and FSH in Holstein heifers decreased further by heat stress in summer when P 4 levels were high during luteal phase. The results demonstrate significant effect of summer heat on reproduction of Hanwoo or Holstein heifers. Although parameters indicating the extent of heat stress were not measured in this study, we suggest that serum hormone levels could be considered as successful indicators of summer heat stress condition for Hanwoo and Holstein heifers even under rather cool summer climate.

In the 7th century, Prince Shoudoku built the Horyu temple at Nara, when Buddhist culture in Japan had highly prospered after Buddhism were transmitted to Japan from Korea. At the same time, the three ancient country of Silla, Koguryo, and Baekjae had generally effected on Japanese culture and life as well as Buddhist events, religious services and sacrificial offerings in form. And even now there are kept above one thousand of tablewares which was used at the age and was made of wood and alloy manufactures from Han peninsular in Seisoin at Nara. Through these historical backgrounds, it could be presumed that the religious services and the sacrificial offerings for Prince Shodoku for above 1300 years help us to study and estimate the ancient dietary culture of Korean and Japanese. There are several points of similarities which are remained and maintained in Han Peninsular. 1. They used high filling method of the secrificial offerings and high receptacles in the religious service. 2. The cakes were mainly made of nonglutinous rice tharr glutinous rice 3. They decorated the pheonix instead of flowers and the other kinds of birds in Korea. 4. Kakiage of fried confectionary was founded in many kinds of them at present.

Coal workers' pneumoconiosis (CWP) and chronic obstructive pulmonary disease (COPD) are characterized as chronic inflammation of the lung in miners exposed to coal mine dust. The aim of the present study was to compare the levels of serum lactate dehydrogenase (LD) and C-reactive protein (CRP) as the inflammatory indices between subjects with CWP and those with CWP and COPD (CWP+COPD), among a total of 97 subjects (27 control, 40 CWP, and 30 CWP+COPD patients). The mean levels of serum LD (165.7 vs 184.6 U/L, p=0.016) and CRP (0.08 vs 0.15 mg/dL, p=0.002) in subjects with CWP were higher than those of in subjects without CWP. The mean level of serum CRP (0.10 vs 0.19 mg/dL, p=0.008) in subjects with COPD was higher than that in subjects without COPD. In an analysis of covariance adjusted by age, the mean level of serum CRP showed statistical significance among the study groups, control, CWP, and CWP+COPD (0.07 vs 0.13 vs 0.19 mg/dL, p=0.005); the mean level of serum CRP in the CWP+COPD group was significantly higher than that of the control group (p=0.001). The results suggest that a high level of CRP in the serum may be associated with CWP and COPD in retired coal miners.
