This study focuses on the genealogical analysis of the urban public spaces by the local history of Seoul which is significantly different from western cities. The analysis targets the discourse of the urban street which defines urban space-structure among the urban public spaces. Based on the analysis, we define the progress levels of urban public design policy in Seoul. Firstly, in 1960's and 1970's, 'urban reconstruction' was intensively carried out for the country modernization, and 'vehicle preferred street expansion' resulted in damages to historical inheritance, in-humanized street, and cultural uniformity. 1980's and 1990's would be defined as 'politic acceptance of plural values to the urban street.' There were the Olympic Games held in Seoul in 1988, which were the celebrations of the 600th capital establishment and the autonomous local government system. In the meanwhile, diverse values on the urban street were discussed in terms of globalization. There also were the self-reflection for the urban skyscrapers and high-population rate, the cultural uniformity of urban street, and the commercialization in downtown with urban reconstruction plans. Then, the sense of landscape and amenity was focused. Various urban projects and regulations were held according to the changes of value recognition. 2000's can be defined as 'introduction to the organic integration and the urban public design governance.' In the 21st century, types of recognition have changed significantly, which include publicness, humanism, sustainability, symbolism, artistry, placeness, and communication. They cause the establishment of ordinances and the installation of integrated organization via urban design administration. The legislation has been revised in order to support the various methods for the maintenance and operation of urban landscape in terms of local characteristics. New regulations were established for residents to participate in the processes of the urban planning with street design policy.

This study examined the ideal type of a man that women prefer and the recognition of men for their own appearance management with the rise of the importance for appearance management today. The prerequisite which matters most in time of considering a man as a date of love predominantly was centered on education, and the prerequisite which goes first among the rest in time of judging a man as the mate of marriage was undoubtedly his financial status. It is regarded that as for a date of love the visual image or the specialty other than the conditions in reality mattered most, and concerning a mate in marriage the actual financial conditions had the priority. When a man is evaluated, the percentage of appearance took the highest rate of 60~80%, and in his appearance, the general harmony was considered as the most important factor. As for the recognition of men for their appearance management, women tend to have an affirmative realization for managing their own appearance in general, and the reason was they believe that the way men take care of their own appearance belongs to personal free will. The perception for a man with a decent appearance was very positive, and the ground for this was that once the appearance looks handsome, he seems gorgeous. The recognition for men's cosmetic surgery showed the affirmation over the average, and an opinion that the settlement of personal appearance complex will help them out emerged as the ground for this affirmation, and so it is regarded that the aesthetic surgery of today and the perception for men's appearance management have become universal phenomena unlike former days with the reflection of visualization of the external visual and lookism shown from various media.

Objectives : The aim of this study was to suggest a new method to estimate the resistance by acupoint compositions by using the multi-frequency bioelectrical impedance analysis(MF-BIA) of 5 kHz, 50 kHz and 200 kHz within 2 cm of acupoints as a local segment. Moreover, we try to confirm the relation to between measured resistance at skin surface and measured resistance by various manual acupuncture needle insertion depth. Methods : Ten male subjects participated in this study. We measured the resistance at left/right ST36 at skin surface and various manual acupuncture needle insertion depth(skin, 5 mm, 10 mm, 15 mm, 20 mm, 25 mm and 30 mm). Results : It was also observed that the all measured resistances were the highest at 5 kHz and the lowest at 200 kHz. There were significant differences at 5 kHz, 50 kHz and 200 kHz between measured resistance at skin surface and measured resistance by various manual acupuncture needle insertion depth(p<0.05). There was no significant difference in the left and right identical acupoints under the identical condition(p>0.05). Conclusions : We conclude that the measured resistance at skin surface has limitation as to reflect the information of tissue. However, the measured resistance at each frequency was changed as similar pattern by different insertion depth. Hence, we confirmed the possibility of assumption on information of tissue which was expected to locate an acupoint.

Purpose: This study was to investigate the reference accuracy in major nursing journals in Korea. Methods: The references in articles from eight nursing journals from 2006 were compared with PubMed for authors, year, title, journal, volume, and page accuracy. Four hundred sixty-six references were reviewed. Errors were classified as major or minor and categorized by bibliographic headings (author, title, journal, year, volume and page). Results: Of the 466 references, 223 (47.9%) had citation errors. The reference error rates ranged from 28.6% to 58.7%. Most errors occurred in the author element (37.9%), followed by title (20.9%), journal (19.0%), page (13.9%), volume (5.9%), and year (2.4%). Conclusion: This study identified a considerable error rate in the references of nursing journals. Inaccuracy of references is a reflection on scholarly work of authors and journals. Authors and Editorial committees are responsible for the accuracy of references.

The standard prestressed concrete I-girder bridge (PSC I-girder bridge) is one of the most prevalent types for small and medium bridges in Korea. When determining the member forces in a section to assess the safety of girder in this type of bridge, the general practice is to use the simplified practical equations or the live load distribution factors proposed in design standards rather than the precise analysis through the finite element method or so. Meanwhile, the live load distribution factors currently used in Korean design practice are just a reflection of overseas research results or design standards without alterations. Therefore, it is necessary to develop an equation of the live load distribution factors fit for the design conditions of Korea, considering the standardized section of standard PSC I-girder bridges and the design strength of concrete. In this study, to develop an equation of the live load distribution factors, a parametric analysis and sensitivity analysis were carried out on the parameters such as width of bridge, span length, girder spacing, width of traffic lane, etc. Then, an equation of live load distribution factors was developed through the multiple linear regression analysis on the results of parametric analysis. When the actual practice engineers design a bridge with the equation of live load distribution factors developed here, they will determine the design of member forces ensuring the appropriate safety rate more easily. Moreover, in the preliminary design, this model is expected to save much time for the repetitive design to improve the structural efficiency of PSC I-girder bridges.

This study reports on a uniform resin coating method by using a doctor blade type dispenser. For high productivity, continuous imprint-lithography has been studied, and developed fabrication systems are used in several applications such as anti-reflection films, dry adhesives, and water collecting surfaces. In the continuous fabrication field, researchers have typically focused on patterning and demolding procedures. During the roll-to-roll fabrication process, however, the uniform resin coating process is also important in order to obtain a high quality product, which can be evaluated by uniform thickness, precise geometric expressions, and a thin residual layer. To achieve these, a doctor blade type dispenser was designed and fabricated. As a result, thickness of coated resin was well controlled by modulating the flow rate of the resin and blading gap. In addition, a very thin layer coating process (${\sim}10{\mu}m$) was achieved by softly contacting the blade on the substrate.

The dependence of electronic properties and local structure of tantalum oxide thin film on oxygen deficiency have been investigated by means of X-ray photoelectron spectroscopy (XPS), Reflection Electron Energy Loss Spectroscopy (REELS), and X-ray absorption spectroscopy (XAS). The XPS results showed that the oxygen flow rate change results in the appearance of features in the Ta 4f at the binding energies of 23.2 eV, 24.4 eV, 25.8, and 27.3 eV whose peaks are attributed to Ta1+, Ta2+, Ta3+, Ta4+, and Ta5+, respectively. The presence of nonstoichiometric state from tantalum oxide (TaOx) thin films could be generated by the oxygen vacancies. The REELS spectra suggested the decrease of band gap for tantalum oxide thin films with increasing oxygen deficiency. In addition, XAS spectra manifested both the increase of coordination number of the first Ta-O shell and a considerable reduction of the Ta-O bond distance with the decrease of oxygen deficiency.

The female image has been changed incessantly with age and has been eminently represented in cosmetic advertisement. The female images are changed from the classical images to the active and professional images with the historical current of cyber, digital, and fusion. These changes in the expression of female image are largely due to the spread of post-modernism, feminism, de-construction (Kim, 1994), digital information revolution, and increase of income. The female images in cosmetic advertisement have been expressed very variously with fashion, marketing target, and characteristics of articles. (Im, 1997) The cosmetic advertisements of pure and graceful images were popular in the past. But nowadays individual image, womanly image, and unchanged beautiful image are in vogue. Individual image is very popular in young generation with very short fashion period. Active career woman image represents passion and beauty with extension of women' social roles. Unchanged beautiful image in modern industrial pollution stands for the desire of keeping the beauty in youth. Brand is very important factor to consumers in purchasing. Brand is no larger the simple concept in the past, and accepted as reflection of the image, social status, service, and life-style(Lee, 1998) consumers are very favorable to foreign cosmetics with the increase of overseas travels and import. This phenomenon is considered as very natural, especially in young generation. To create a successful brand image, the harmony of quality, psychological preference, advertisement, and reasonable price are required. According to the questionnaire research implemented by the subject of college women students in five universities in Seoul, the majority of college women students purchase domestic cosmetic brands in cosmetic specialty stores and depend on the tips of acquaintances. Quality, skin-trouble, and brand are considered as special regards for purchasing. Especially, internet shopping in purchasing marks high growth rate and preference for foreign cosmetics is very ardent. It can be expected that the 21st century is the epoch of various small production different from the mass-production in the 20th century. Female image will be probably expressed with individual, emotional, and professional image in the media of digital, fusion, cyber, and technology culture. It can be said that the tendency of cosmetic purchasing in the future will be more focused on brand image and life style.

This study developed a pigment by doping Cr to Pyrochlore-type stannate crystals and investigated the chromogenic relationship in a glaze. Crystal phases of the pigment according to firing temperatures were analyzed by XRD, and the doping relationship was analyzed by Raman Spectroscopy. Color and reflection rate of the pigment were measured by UV-vis Spectrophotometer. Consequently, stannate characteristic band appeared at 307, 408, 505 and $755cm^{-1}$ until 0.1 mole substitution of $Cr_2O_3$. However, as amount of $Cr_2O_3$ increased, the stannate characteristic peak was decreased and shift happened at the left hand side due to Cr-dope. In composition of 0.12~0.14 mole substituted, the unreacted $Cr_2O_3$ stannate characteristic peak, which was not engaged, was shown. This result shows the maximum limit of solid solution was 0.1 mole $Cr_2O_3$. The color of the glaze, which was produced by adding 6 wt% of $Y_2Sn_{1.94}Cr_{0.06}O_7$ pigment in a lime or a lime-magnesia glaze and fired the mixture at $1260^{\circ}C$, was grayish pink with $L^*$ 70.29, $a^*$ 5.68 and $b^*$ 6.27. It showed gray with $L^*$ 68.82, $a^*$ 3.07and $b^*$ 8.13 for $Y_2Sn_{1.9}Cr_{0.1}O_7$.

Regional geophysical surveys and geological cal studies on natural gas hydrate (NGH) in the East Sea were carried out by the Korea Institute of Geoscience and Mineral Resources (KIGAM) from 2000 to 2004. 16 piston cores, 2270 L-km of multi-channel reflection seismic (MCRS) data and 730 L-km of 3.5kHz Chirp data obtained from the southwestern part of the deep-water Ulleung Basin were analyzed in this study. In piston cores, cracks generally developed parallel to bedding suggest significant gas content. The core analyses showed high total organic carbon (TOC) content, sedimentation rate and heat flow of sediments. These are in favor of the general ion of substantial biogenic methane, which can form the NGH within the stability zone of the near seafloor sediments in the study area. The cores generally show also high residual hydrocarbon gas concentrations for the formation of natural gas hydrates The geophysical indicators of the presence of gas and/or NGH such as bottom simulating reflectors (BSRs), seismic blank Bones, pockmarks and gas seeping features were well defined on the MCRS and Chirp data.
