We have been performing a wide-field photometric monitoring program, named SPVS (Short-Period Variability Survey), at the Bohyunsan Optical Astronomy Observatory (BOAO). The observation system consists of a small refracting telescope (D = 155 mm, f = 1050 mm) and a $2k{\times}3k$ CCD Camera. The field of view is $1.0^{\circ}{\times}1.5^{\circ}$. Detection limit is about V = 13 for short-period small amplitude variables such as ${\delta}$ Scuti-type pulsating stars, and about V = 15 for long-period large amplitude variables such as eclipsing binaries and RR Lyrae stars. The instrument is designed to be remote-controlled through internet. The primary purpose of this project is to search for variable objects in bright Galactic open clusters. We present results of test observations conducted towards NGC 7092.

Purpose : The purpose of this study was to develop core competency of midwife practices to improve midwifery education, national examination and clinical practices. Method: Literature and. document review and internet search and survey were used. 127 registered in the Korean Midwifery Association midwives by structured instrument were surveyed to analyze midwife's practices and work situation. Result : Midwifery education program has to be either a post graduate or a graduate program for people with nursing license. Midwifery practice has to be extended to a lifelong health care of all women including non-pregnant women, not just a health care of pregnant women and newborns. Thus, a primary health care of women, laws/ethics, and management skills were included in the core competencies of midwifery practice considering the international trend of future-oriented and extended role of a midwife. Also, newborn care and ability to cope with emergency situations were emphasized based on the midwife´s opinion. Conclusion: This study has to be developed midwifery practices and education and the standard of midwifery practice has to be stated based on that result.

As the knowledge-based society progresses the amount of information increases tremendously and also the accessibility to information is much improved through the diffusion of internet and digitalized contents. At this juncture the systematic management and efficient analysis of immense information surfaces as a global issue. And the paradigm of information turns from the age of information access to the age of information analysis. So it is urgently required to analyze technology trend from technology information and to establish the way to realize a systematic method for information analysis. Accordingly in this study an information analysis system is developed that contributes to the decision of proper direction for R&D and technology development by rapidly and systematically analyzing search results from the technology databases online and can reduce to a great degree the shorts and time required to collect and analyze information.

The purpose of this study is to provide for efficient health information service which doctors may use for their better medical practice and scientific research. 177 doctors were surveyed from December 3 to December 21th in 2007. This study mentioned activities of information need and use that were evaluated by information gathering methods used, information source, frequency of use, and degree of satisfaction toward library services. Doctors showed that they need information mainly to know the recent research results in their interesting subject field and to treat a patient. Doctors trended to obtain information through internet search because easy access and easy use, accuracy and up to dateness of information use. Doctors trended to seek information mainly through library, but they showed relatively low frequency of library use because they do not know how to use it.

Since digital images and videos are rapidly increasing in the internet with the spread of mobile computers and smartphones, research on image retrieval has gained tremendous momentum. Color, shape, and texture are major features used in image retrieval. Especially, color information has been widely used in image retrieval, because it is robust in translation, rotation, and a small change of camera view. This paper proposes a new method for histogram refinement based on local color difference. Firstly, the proposed method converts a RGB color image into a HSV color image. Secondly, it reduces the size of color space from 256³ to 32. It classifies pixels in the 32-color image into three groups according to the color difference between a central pixel and its neighbors in a 3x3 local region. Finally, it makes a color difference vector(CDV) representing three refined color histograms, then image retrieval is performed by the CDV matching. The experimental results using public image database show that the proposed method has higher retrieval accuracy than other conventional ones. They also show that the proposed method can be effectively applied to search low resolution images such as thumbnail images.

Objectives: To review the history, method, parameters, system of electrogastrography(EGG) and to study its oriental medical application in Traditional Chinese Medicine. Methods: We investigate the research results through internet search engine, CNKI (China National Knowledge Infrastructure). Results: In China, EGG was studied on various regions, including multifarious regions of Traditional Chinese Medical. And also regions of Traditional Chinese Medical could divide classification of diseases, herbal medicine, acupuncture and the like. Conclusions: EGG is a noninvasive, easy and painless method that is kept recordings of the electrical activity of the stomach, therefore it has used for studies and clinics widely. EGG in Traditional Chinese Medicine has used an objective parameter that verified efficacies of oriental medicine. I would therefore like to conclude that there should be continued study and active application of EGG in the wide variety of oriental medicine.

Purpose: To review the Scale Measurement studies on Traditional Chinese Medicine and it's prospection. Method: The papers reviewed in this study were searched through internet search engines such as China National Knowledge Infrastructure(www.cnki.net). we searched papers on Scale studies by the keyword "量表"(Scale) and "中醫"(TCM). Results: 263 papers which is truly related on "Scale" were collected. All the papers were reviewed briefly under the subtitle of diagnosis, evaluation of curative value, development of scale, reverse of overseas questionnaire to chinese literature and etc. Conclusions: Scale measurement studies on TCM proceeded so much but their medical application was on small and narrow field. Also Scale study had TCM's characteristics were only 18% of them. Neverthless, productions from China were precious and valuable to Korean Oriental Medicine and we have to learn their success on scale measurement studies.

In most libraries and information centers, access versus ownership is the new dilemma facing in view of the rapidly change of information technologies, the rising costs of serials, and not equally increasing budgets. And libraries and information centers are now confronted with the fact that the more users bypass the library's resources in favor of the results they can get with an ordinary Internet search engine. The purpose of this study is to analyze a difficult problems related to information resources development in digital world with priority given to accesscentered paradigm, the grounds of an argument and fallacy of physical collection building, and limitations of electronic publication.
