Color laser printers are nowadays abused to print or forge official documents and bills. Identifying color laser printers will be a step for media forensics. This paper presents a new method to identify color laser printers with printed color images. Since different printer companies use their own printing process, each of printed papers from different printers has a little different invisible noise. After the wiener-filter is used to analyze the invisible noises from each printer, we extract some features from these noises by calculating a gray level co-occurrence matrix. Then, these features are applied to train and classify the support vector machine for identifying the color laser printer. In the experiment, we use total 2,597 images from 7 color laser printers. The results prove that the presented identification method performs well using the noise features of color printed images.

Today scientific and technological activities for development raise a whole series of problems with the institutionalization and the professionalization of science, but also with the increasingly obvious links between technologies, innovation and production of goods and services, and the difficulties caused by relationship between sovereign one. Solving these problems therefore requires discussion, agreements, and consensus, not only with the Korean Government, where present budget difficulties demand trad-offs between scientific and technological activities and other forms of technical assistance on the one hand, and other R&D objectives on the other. The purpose of this paper is to examine the problems facing auther's own experiences in this connection and to show what kinds of solutions they have been applying in order to identify some useful inputs through consulting engineer for discussion. It is based on very general accounts of the policies, institutions and activities of about own experiences and, even for those, only on rather limited, fragmentary information derived from the few official documents.

Introduction : Attention-deficit hyperactivity disorder (ADHD) was a newly coined term for a disease that existed prior to its naming in the mid 20th century. The issue about whether ADHD is a new disorder or merely a new name for an existing disorder is still controversial. The authors tried to find the clues to the answer for this question through reviewing historical documents for traces of ADHD. Contents : We could find literatures and medical records that contain possible ADHD symptoms. In particular, in 1845, Heinrich Hoffmann's 'fidgety Philip' or 'Johnny Look-in-the-air' nearly satisfies today's criteria for ADHD. Methylphenidate was approved as a promising chemical for inattention in 1957 before the establishment of the concept of ADHD. In 1968, ADHD was first officially introduced as "Hyperactivity Reaction of Childhood" by DSM-II. In 1980, DSM-III, 'Attention Deficit Disorder (ADD)' was adopted as an official diagnostic term and changed to 'ADHD' since the creation of DSM-III-R in 1987. Conclusion : As stated above, ADHD has existed since long ago and became familiar via an advanced diagnostic system and therapeutic options.

Background: Singapore has the stable healthcare system with utilizing pharmacist manpower in proper positions by demand of populations' health among Asian countries. Objective: This study aims to systematically review (1) the pharmacists' role and (2) the pharmacy education system of Singapore in comparison with Korea. Method: We searched for information about academic, medical and governmental institutions related to professional pharmacists' practice in Singapore by primarily using database such as DBpia, KISS, Google Scholar and ProQuest and the official website of the Singapore Ministry of Health. We contacted and arranged the visit schedules with National University of Singapore, National Health Group's polyclinics, Agency for Integrated Care, National University Hospital, and community chain pharmacies. During onsite visits, we interviewed pharmacists working in each institution and obtained additional documents and materials relevant to this manuscript work. Results: To become a registered pharmacist in Singapore, the pharmacy curriculum requires four full-time academic years and six additional months allotted for pre-registration training. Pharm.D. course is offered for pharmacy graduate students with additional two full-time years of study. Team teaching and inter professional education program seem the most significant method in pharmacy education. Pharmacists working at hospitals, polyclinics, and community pharmacies in Singapore take broader roles and offer more cognitive services such as smoking cessation program and medication reconciliation. Especially, pharmacists in Agency for Integrated Care fill the role of primary care providers for the continuing care of the community through the governmental support toward the patients-centered integrated care. Conclusion: Singaporean pharmacists take significant and active roles in collaboration with other healthcare providers. Efforts such as interprofessional pharmacy education and governmental endorsement of the systematic and interactive care between pharmacists and other medical providers in Singapore are needed to be urgently applied to Korea healthcare system for the promotion of population health.

The Gamrotenghwa of the Choson Dynasty is a unique genre of buddhist painting in that the destiny of the dead souls and the guidance to nirvana are expressed in reality. More than 50 of the Gamrotenghwa are known to be present, and the lower part of the paintings includes a wide assortment of folk customary scenes reflecting the social life style of the time when the painting was drawn, such as difficulties in life. public life, punishment and war. Changes in the costume of the people shown on the customary scenes of the Gamrotenghwa according to the time based changes in painting style were investigated in this study. The results are summarized in three points. First, the costumes of bureaucrats showed a tendency of preservation without any major changes in the painting. On the other hand, costumes of public and entertainer in the scenes were very close to those worn by the people at that time. The realistic description of public life in the painting may establish the value of the Gamrotenghwa as the historical documents. Second, the costume of the people in the painting showed a dual structure as the social positions; bureaucrats wore various official hats, large coats and belts to expose their social prestige. while the general public wore simple and convenient clothing which is divided into shirt and pants. The dual structure of the costume in the painting is in well accordance with that of the later period of Choson dynasty, suggesting that the customary scenes in the painting represent the social life style of the period. Finally, the customary scenes in the Gamrotenghwa are very variegated. which shows a variety of beauty of wearing even though they look coarse in a sense. The diversity of wearing beauty in the picture may contribute to the recreation of the beauty of shape in the new design of Hanbok.

The importance of the standards and its related texts established by Codex Alimentarius Commission (CAC) had been increased by the Agreement of Application of Sanitary and Phytosanitary Measures (SPS Agreement) in World Trade Organization (WTO). To meet the needs of WTO SPS Agreement, biennial CAC meeting had been changed to every year. This study was conducted to analyze the effects on interval between CAC meetings. The years of adoption, revision and amendment of CAC texts were collected from the official standard list and individual texts from CAC homepage. The period since establishment of CAC was divided into four groups by starting negotiation of Uruguay Round, WTO foundation and reducing the interval between CAC meetings. The collected data were analyzed by SPSS program. The numbers of CAC standards, guidelines, recommendations, maximum residue levels, and miscellaneous texts were 202, 56, 46, 3 and 5, respectively. Since 8 documents didn't contain the adoption year, these texts were eliminated to analyze adoption year. For adoption, annually 11.26 texts were established since establishment of CAC and there were no significant difference among the 4 groups. However the average numbers of revisions and amendments of adopted texts for overall periods and for each period were 7.56, 0.93, 6.50, 17.20 and 19.75, respectively. The average numbers of overall decisions, defined as summation of adoption, revision and amendment of texts, for overall periods and for each period were 12.37, 6.27, 9.00, 17.40 and 29.25, respectively. There were significant differences by the WTO foundation and the interval between CAC meetings. The reduced interval of CAC meetings influenced to increase number of revisions and amendments of adopted texts, but not yet adoption of new text.
