The purpose of this study was to investigate clothing behavior and ornaments wear of university students. The subject of this study consists of 241 college students who were attended in Kongju National University. SPSSWIN Program was utilized to calculated frequency(N), mean value(M) and standard deviation(SD) for statistical analysis. Differences among the populations were examined through T-test, F-test, $x^2$-test. The results of this study were as follow : 1. Clothing behavior of university students had significant difference according to sex, grade. In general, female students showed higher score than did male students in clothing interest, clothing conformity, self-estimation about clothing, clothing dependence, clothing aesthetic, clothing modesty, A first-year students had high tendency in clothing interest. 2. The wear of ornaments had significant difference according to variables. Buying the ornaments, most of students sot information in show window and emphasized on design. Male students wanted to have the ornaments of shoes, watch, hat & necklet, but female students wanted to have the ornaments of shoes, earring, necklet & hairpin. 3. Clothing behavior has Influenced university students' ornaments wear. The university students who appeared to be interested in clothes were apparently influenced by peers when selecting ornaments. Ornaments were usually bought in the department store, while belts were among the most popular choices. Students who stressed color when purchasing ornaments showed a high level of interest in and dependence on clothes. On the basic of these results, we can conclude that university students' taste in clothing behavior and use of ornaments wear depend on several different factors. Therefore, it is possible to outline the shift in clothing attitudes during adolescence. In order to understand university students' behaviour concerning clothes, much guidance and various studies on the subject are much recommended.

Since the 18th century the museums in Europe have accepted the social demand of the publicity and have played a role of social education and it lasted to the present. Recently, the society began to change it's direction. It is from the Universalism to the Pluralism. The Universalism is due to democratic society after 'the Civil Revolution' and standardized social system after 'the Industrial Revolution' The Pluralism that starts with the decrease of the modern society is about the diversity and the activation of identity which has been disregarded since the Modernism. This study is to analyze and to clarify how the museum's educational environment which had begun since the 18th century has been changed since 1990 and how these are related to the social alteration from the Universalism to the Pluralism. As a result of this study, it was confirmed that there had been a simple circulation system and a unified spatial experience in the museum of Europe since 18th century to 1980's(phl) while there had been a complex circulation system and a diverse spatial experience in the museum of Europe after 1990's(ph2). These mean that the museum of phl gave a unified social education to the visitors and they came to have a similar knowledge and emotion after their seeing the exhibition material while the museums of 'ph2' gave a diverse one and the visitor came to have a different knowledge and emotion to the same exhibition material. The museum which gives a unified social education is to produce a unified thoughts of people and it is because the social direction is the Universalism. In addition to this, the museum of diverse social education is to produce people of diversity and it is related to the Pluralism.

In this paper, we propose a vanishing point detection method using multiple initial vanishing points. Vanishing points are important geometric information that is used for reconstructing 3D structures. Three vanishing points are detected for indoor scenes. In the previous work, it could be inaccurate to detect only one initial vanishing point, because initial vanishing point getting most highest sum of voting could be deferent from the best initial vanishing point. Therefore the method which sets multiple initial vanishing point and detects a best vanishing point from them gives us preparation for the prior case. Also in this paper, we propose a adjusting vanishing point method by postprocessing of detected vanishing points. We could detect more accurate vanishing point by using postprocessing. Experimental results show that the accuracy of the vanishing point detection is about 1~2% higher than that of the existing method through the proposed method and the performance is improved accordingly.

The concentrations of dimethylsulfide (DMS) were determined using samples collected from a station located at Kosan, Cheju Island during two field campaigns held in December 1996 and January 1997. The atmospheric DMS concentrations measured at 6-hr intervals during the entire campaign periods, after excluding a few extreme values, spanned in the range of 14 to 410 pptv with mean and 1 SD value of 127 $\pm$ 94 pptv (N=42). Between two month periods during which the field campaigns were conducted, a notable reduction in DMS levels was observed which was comparable to the dramatic shift in air temperature. A considerable difference was also noted in DMS levels, when data were grouped by day/night basis. The cause of unexpected, high day-to-night DMS ratios is best explained in terms of high efficiency of daytime source processes relative to low efficiency of nighttime sink processes due to the characteristics of the study location. The surface water DMS of the study site, although scarcely measured, also behaved similarly to its atmospheric counterpart with its range from 0.3 to 19 nM (N=11). When correlation analysis was conducted between the atmospheric DMS concentration and other concurrently determined parameters, significant correlations were observed from most basic meteorological parameters such as windspeed, relative humidy, and air temperature. However, the existence of "not-so-strong" correlations between air temperature and DMS concentrations relative to other ones indicated that the effect of temperature on DMS behavior must be reflected in more complicated manners at the study site. The sea-to-air flux of DMS was approximated through an application of the mass-balance flux calculation method of Wylie and de Mora (1996) under the assumption that sink mechanism within the marine boundary layer is in steady-state condition with its counterpart, source mechanism. Based on this estimation method, we reached a conclusion that oceanic DMS emitted from the southwest sea of the Korean Peninsula can amount to approximately 9 $\sim$ 36 Gg S $yr^{-1}$.$yr^{-1}$.

The interaction between a calcium channel blocker nifedipine and atrial natriuretic peptide (ANP) was examined in normotensive and renal hypertensive rats. The infusion of either ANP or nifedipine produced a significant decrease in mean arterial pressure (MAP). The combined infusion of ANP with nifedipine resulted in a greater fall of MAP than did the infusion of each drug alone. ANP significantly increased urinary volume and excretion of sodium, while nifedipine was without effects. The diuretic/natriuretic effects of ANP were potentiated by the combined infusion with nifedipine. The vasodepressor and renal effects of ANP or nifedipine were qualitatively similar between the normotensive and hypertensive rats. Nifedipine caused an upward and leftward shift of the ANP dose-relaxation curve of the phenylephrine-precontracted thoracic aortic rings isolated from the normotensive rats , suggesting that the vasodilation sensitivity to ANP is increased in the presence of nifedipine. These results indicate that nifedipine enhances the vasodepressor effect of ANP, the likely mechanisms being attributable to a contraction of effective intravascular volume as a consequence of potentiated renal excretion and a greater peripheral vasodilation.

Purpose: This study was done to analyze variations in unit staffing and recommend policies to improve nursing staffing levels in intensive care units (ICUS). Method: A cross-sectional study design was used, employing survey data from the Health Insurance Review Agency conducted from June-July, 2003. Unitstaffing was measured using two indicators; bed-to-nurse (B/N) ratio (number of beds per nurse), and patient-to-nurse (P/N) ratio (number of average daily patients per nurse). Staffing levels were compared according to hospital and ICU characteristics. Result: A total of 414 institutions were operating 569 adult and 86 neonatal ICUs. Tertiary hospitals (n=42) had the lowest mean B/N (0.82) and P/N (0.76) ratios in adult ICUs, followed by general hospitals (B/N: 1.34, P/N: 0.97). Those ratios indicated that a nurse took care of 3 to 5 patients per shift. Neonatal ICUs had worse staffing and had greater variations in stafnng ratios than adult ICUs. About 17% of adult and 26% of neonatal ICUs were staffed only by adjunct nurses who had responsibility for a general ward as well as the ICU Conclusion: Stratification of nurse staffing levels and differentiation of ICU utilization fees based on staffing grades are recommended as a policy tool to improve nurse staffing in ICUs.

We fabricated nano-particles of ZnO, $In_2O_3$ and $SnO_2$ by using the chemical reaction between metal thin films and polyamic acid. The average size and density of these ZnO, $In_2O_3$ and $SnO_2$ nano-particles was approximately 10, 7, and 15 nm, and $2{\times}10^{11},\;6{\times}10^{11},\;2.4{\times}10^{11}cm^{-2}$, respectively. Then, we fabricated nano-floating gate memory (NFGM) devices with ZnO and $In_2O_3$ nano-particles embedded in the devices' polyimide dielectrics and silicon dioxide layers as control and tunnel oxides, respectively. We measured the current-voltage characteristics, endurance properties and retention times of the memory devices using a semiconductor parameter analyzer. In the $In_2O_3$ NFGM, the threshold voltage shift (${\Delta}V_T$) was approximately 5 V at the initial state of programming and erasing operations. However, the memory window rapidly decreased after 1000 s from 5 to 1.5 V. The ${\Delta}V_T$ of the NFGM containing ZnO was approximately 2 V at the initial state, but the memory window decreased after 1000 s from 2 to 0.4 V. These results mean that metal-oxide nano-particles have feasibility to apply NFGM devices.

Under natural conditions, rivers do not in general take straight courses but instead take winding courses. This is known as meandering of rivers. Meandering of rivers are so complicated because of the mutual interactions between flow and movable boundaries. In quantitative information, it is important to predict the future location of a river channel(channel migration) because in selecting a bridge site or a location of a road. It may be valuable to know the future impact of a nearby river on those structures. When the prediction model of the migration of channel is used in domestic rivers with high coefficient of river regime, it is rational to use the periodical dominant discharge (PDD), which is named firstly by the author, instead of the average discharge. According to the analysis of the erosion coefficient, the mean deviation on the channel migration, and the bed scour factor, it can bring shedding light on the fact that the discharge is one of the dominant components in channel migration. In project area, the discharge that can shift the channel is slightly greater than 6,000CMS. The prediction model of the migration of channel estimated the erosion coefficient, $E_0$ by the data from the South Han River. This estimated value from the South Han River was also used to predict the migration of the South Han River in year 2000.

Population aging is a shift in the distribution of a country's population towards older ages. This is usually reflected in an increase in the population's mean and median ages, a decline in the proportion of the population composed of children, and a rise in the proportion of the population that is elderly. Population ageing is widespread across the world. Barrier-free or Design for All concept consists of modifying buildings or facilities so that they can be used by people who are disabled or have physical impairments. Design for All criteria are aimed at ensuring that everyone can participate in the Information society. Safety-related products being easy to adapt according to different needs, or using standardized interfaces that can be accessed simply by using assistive technology. To this end, policy makers and service providers, especially in the ubiquitous technologies, produce new technologies, products, services and applications for pedestrians.
