In the print world libraries have served as the archival repository for journals that they owned. In the age of digital information, however, with the licensing of electronic journals libraries purchase access to journal contents rather than paying for ownership. Libraries note the potential benefits of electronic journals, but also quake at the thought of inaccessible electronic journal contents caused by lack of preservation, changing technology, or publisher requirements. It is real that libraries have not yet stepped in to create archives of the electronic journals they are purchasing. In the digital environments, publishers, libraries, and other information providers are not the independent units that we used to be. It will take us all working together to solve the problem of preserving access to electronic journals. Thus, it is reasonable that a national library would be charge of making a comprehensive archiving policy on electronic journals, and that cooperative agreements of local libraries can help divide responsibility for different subject areas or materials.

The traditional culture has been developed for a long time with an unique property according to folk character, custom and environment within an area. Especially in 1906, when the westerners were interested in oriental cultures more and more, Paul Poiret presented Japanese traditional dress of napping sleeve coats and harem pants, henceforth japanese fashion theme began to rise. The Japanese style rose as an important fashion item of the modern fashion, with various fashion themes such as orientalism, ethnic, folklore, ecology, etc., needless to say of activities of Japanese designers. The revealed patterns on Japanese dress and it's ornament plays a role of expressive decoration as well as stand for the nation, the ideology of the age and aesthetic consciousness. For this reason, it is necessary to study Japanese traditional patterns expressed in modern fashion systematically. Therefore, in this research, the demonstrated Japanese traditional patterns on the modern fashion were divided into natural, artificial and complex design and were looked out the characteristic, furthermore it was studied in regard that Japanese patterns were how to apply in modern fashion. It was concluded that the characteristics of the Japanese traditional patterns presented in the modern fashion were as follows: first, creation of environmental friendly design using plenty of natural materials; second, expression of paint-like impression and beauty of margins by simplifying of patterns; third, expression of amusing design by using bright colors and print; finally, various patterns were spreaded out complicated on dress. The characteristics of Japanese traditional patterns in the above were expressed in the modern fashion.

The main purpose of this study is to generate a fine copper oxide powder of high purity, with a compact structure and a uniform particle size by a spray pyrolysis process. The raw material is a waste copper chloride solution formed in the manufacturing process of Print Circuit Board (PCB). This study also examines the influences of various factors on the properties of the generated powder. These factors include the reaction temperature, the inflow speed of the raw material solution, the inflow speed of the air, the size of the nozzle tip, and the concentration of the raw material solution. It is discovered that, as the reaction temperature increases from 80$0^{\circ}C$ to 100$0^{\circ}C$ , the particle size of the generated powder increases accordingly, and that the structure of the powder becomes much more compact. When the reaction temperature is 100$0^{\circ}C$, the particle size of the generated powder increases as the concentration of copper in the raw material solution increases to 40g/l, decreases as the concentration increases up to 120g/l, and increases again as the concentration reaches 200g/1. In the case of a lower concentration of the raw material solution, the generated powder appears largely in the form of CuO. As the concentration increases, however, the powder appears largely in the form of CuCl. When the concentration of copper in the raw material solution is 120g/1, the particle size of the generated powder increases as the inflow speed of the raw material solution increases. When the concentration of copper in the raw material solution is 120g/1, there is no evident change in the particle size of the generated powder as the size of the nozzle tip and the air pressure increases. When the concentration is 40g/1, however, the particle size keeps increasing until the air pressure increases to 0.5kg/$\textrm{cm}^2$, but decreases remarkably as the air pressure exceeds 0.5kg/$\textrm{cm}^2$.

Toxicogenomics using microarray technology offers the ability to conduct large-scale detections and quantifications of mRNA transcripts, particularly those associated with alterations in mRNA stability or gene regulation. In this study, we developed the HazChem Human Array V2 using the Agilent Sure-Print technology-based custom array, which is expected to facilitate the identification of environmental toxicants. The array was manufactured using 600 VOCs and PAHs-specific genes identified in previous studies. In order to evaluate the viability of the manufactured HazChem human array V2, we analyzed the gene expression profiles of 9 environmental toxicants (6 VOCs chemicals and 3 PAHs chemicals). As a result, nine toxicants were separated into two chemical types-VOCs and PAHs. After the chip validations with VOCs and PAHs, we conducted an expression profiling comparison of additional chemical groups (POPs and EDCs) using data analysis methods such as hierarchical clustering, 1-way ANOVA, SAM, and PCA. We selected 58 genes that could be classified into four chemical types via statistical methods. Additionally, we selected 63 genes that evidenced significant alterations in expression with all 13 environmental toxicants. These results suggest that the HazChem Human Array V2 will expedite the development of a screening system for environmentally hazardous materials at the level of toxicogenomics in the future.

The application of inkjet technology has been broadening from home printers to manufacturing tools. Recently, there have been demands for high-resolution printing, especially in the field of printed electronics applications. To improve upon the conventional inkjet printing patterning method, electrohydrodynamic (EHD) inkjet technology has recently attracted attention because droplets smaller than the nozzle diameter can be ejected and materials with wider viscosity range can be used for jetting. In this study, an EHD jet printing system for fine patterning is presented. To print various patterns based on drop on demand printing, vector and raster printing algorithm are implanted in the printing software. Fine conductive patterns with line width of less than $7{\mu}m$ can be easily achieved via EHD jet using a nozzle with inner diameter of $8{\mu}m$.

The researches into dimension of image by sexy clothing make that female mainly consist of in their twenties during May to October in 2003. The independent variables were: 1) The physical beauty dimension, 2) The negative estimate dimension, 3) The characteristic devaluation dimension,4) The elegance/ high grade dimension,5) The freshness/ beauty dimension,6) The sex appeal/ exposure dimension. Judging from each characteristic of costume in classified by articles, that is, colors, texture, shapes, details, and others-phenomenon of outerization of under clothing, print. We can know the clothes showing up our nice figures are the sleeveless design tied with strap, soft texture as silk chiffon and the colors that are not strong. And there were no embarrassed, ugly and pitiful clothing. Expressing sexy beauty by clothing is the result that the wearer produces intentionally by compounding design factors, it's the ideal when the observer's reaction and the wearer's intention correspond. Therefore, it will be helpful in expressing ideally if the subject, what kinds of sexy beauty the compounding design factors express, is studied carefully. Also it is expected to be used in grasping modem consumers' desires that want to look sexy, finding out how to express, dealing with the consumers' desires correctly, and the reference materials of the planning goods, sales promotion, and selecting of a medium of advertisement according to the consumers' desires.

Objective: To analyze and compare the age of data in contemporary research articles published in representative general radiology journals. Materials and Methods: We searched for articles reporting original research studies analyzing patient data that were published in the print issues of the Korean Journal of Radiology (KJR), European Radiology (ER), and Radiology in 2017. Eligible articles were reviewed to extract data collection period (time from first patient recruitment to last patient follow-up) and age of data (time between data collection end and publication). The journals were compared in terms of the proportion of articles reporting the data collection period to the level of calendar month and regarding the age of data. Results: There were 50, 492, and 254 eligible articles in KJR, ER, and Radiology, respectively. Of these, 44 (88%; 95% confidence interval [CI]: 75.8-94.8%), 359 (73%; 95% CI: 68.9-76.7%), and 211 (83.1%; 95% CI: 78-87.2%) articles, respectively, provided enough details of data collection period, revealing a significant difference between ER and Radiology (p = 0.002). The age of data was significantly greater in KJR (median age: 826 days; range: 299-2843 days) than in ER (median age: 570 days; range: 56-4742 days; p < 0.001) and Radiology (median age: 618; range: 75-4271 days; p < 0.001). Conclusion: Korean Journal of Radiology did not fall behind ER or Radiology in reporting of data collection period, but showed a significantly greater age of data than ER and Radiology, suggesting that KJR should take measures to improve the timeliness of its data.

Background: Recently clinical trials have expanded extensively in Korea; thus, ensuring the rights of subjects participating in clinical trials is imperative. Accordingly, national regulations on subject recruitment advertisement were enforced from October 25, 2018. In this study, the effect of this regulation was evaluated by analyzing the difference in the provision of information before and after enforcement of the regulation. Methods: Recruitment advertisements for clinical trial subjects 3 years before and after enforcement of the regulation were collated by the significance sampling approach. Print-based (newspapers, buses, and subways) and web-based (clinical trial center websites and online platforms) materials for recruitment in clinical trials of phase 1 to 4 for investigational drugs, medical devices, and oriental medicine were considered. Chi-square tests were conducted for inter-group comparisons. SPSS version 26 was employed for statistical analyses. Results: A total of 137 advertisements were collected comprising 60 pre- and 77 post-regulation enforcement. The overall rate of delivery of critical information in advertisements increased significantly from 47.5% before regulation to 93.2% after regulation enforcement. Particularly, details on expected adverse events augmented significantly (p<0.001). Benefits from participation in clinical trial reduced significantly from 88.3% to 70.1% (p<0.05). As the information provision amplified, the inclusion of professional terms increased. Conclusions: Enforcement of regulations has led to a surge in the amount of information and challenging terms contained in advertisements for recruiting subjects. Therefore, additional efforts are required by subjects to completely understand the information provided in the advertisements.
