As XML documents are getting bigger and more complex, a keyword-based search method that does not require structural information is needed to search these large XML documents. In order to use this method, not only all keywords expressed as nodes in the XML document must be labeled for indexing but also structural information should be well represented. However, the existing labeling methods either have very simple information of XML documents for index or represent the structural information which is difficult to deal with the increase of XML documents size. As the size of XML documents is getting larger, it causes either the poor performance of keyword search or the exponential increase of space usage. In this paper, we present the Repetitive Prime Labeling Scheme (RPLS) in order to improve the problem of the existing labeling methods for keyword-based search of large XML documents. This method is based on the existing prime number labeling method and allows a parents prime number to be used at a lower level repeatedly so that the number of prime numbers being generated can be reduced. Then, we show an experimental result of the comparison between our methods and the existing methods.

Retropharyngeal abscesses are uncommon but potentially lethal infections, especially in the pediatric population. In adults, retropharyngeal abscesses are very rare and usually secondary to chronic tuberculous cervical spine osteomyelitis. Retropharyngeal tuberculosis can manifest itself as a cold abscess, and the symptoms and signs are usually influenced by its size and location. We present two cases of retropharyngeal abscess in adults without tuberculous cervical osteomyelitis.

Dermoid cysts are developmental anomalies that represent the simplest form of teratoma. They are the result of the sequestration of the skin along the lines of embryonic closure. These cysts of the head and neck are uncommon and account for 7% of all dermoid cysts. They are predominantly found in the orbit, floor of mouth, and nose. As a dermoid cyst of the parotid gland is extremely rare, it is often misdiagnosed preoperatively. By way of imaging modalities such as computed tomography, MRI and ultrasongraphy along with FNAB, it can be differentiated from many other cystic lesions of the parotid gland. We report a case of dermoid cyst of the parotid gland which masqueraded as lipoma before complete surgical excision.

Problems and current situation of public health globally and domestically were analyzed in this study and based on these findings, ways to improve from western medicine and Oriental medicine can be deduced as follows: 1. Current problems of public health in Korea and the world 1) Increase of diseases resulted from daily habits and infectious diseases, many are at the brink of being ill. Quality of life from extended life span and unbalanced health care must be solved. 2) Natural and societal factors including host factors, public health service, and other external and internal factors play an important role in deciding healthy and being ill. 3) Some of the limits and problems of modem medicine include insufficient academic knowledge and incomplete theory, as well as misled approach to the treatment. Human itself isn't perfect organism and other realistic problems hinder one's well-being. 4) Regardless of western medicine or Oriental medicine, patients were approached as someone with diseases and disorders, and wholistic approach was disregarded. Lack of clinical training, absence of clear educational philosophy and goal are some of the reasons why the education isn't under concrete system 2. Important factors for the medical education and proper direction for the education of Oriental medicine 1) Important factors for medical education - Education should not be limited on the human health and illness, but also cover qualities such as well-being, social welfare, service, and happiness. Every aspects of human life must be considered and attended for more productive outcome. - Basic understanding of humanity must be included in the educational curriculum - Foundation of human diseases and pain are associated with inner life and surrounding causes including family, society, nature, race, culture, religion, politics, and etc., thus the education must be approached to recognize aforementioned criteria. 2) Proper direction for the education of Oriental medicine - Values of Oriental medicine for medical principles and importance of lifehood must be educated. - Educational goal, limits, and levels must be established for the school of Oriental medicine - Respect for life must be the top priorities of educational direction which should lead to solution based education for the human health. Latest medical theory and technology should be accommodated as well as prevention, treatment, and balancing of basic courses and clinical training for optimal education.

Health promotion program utilizing traditional korean medicine(TKM) is very unique modality uncommonly conducted throughout the world. Korea's TKM public health services went through initial stage from 2001 and spread throughout the country by 2003. 35 public health centers in the nation is appointed as 'TKM health promotion HUB' and in operation from 2007. But the program is still in the early state and evaluation of usage, satisfaction, and community service is still in demand. This study aims to verify current situations of TKM public health service by examining public awareness, usage, and satisfaction and suggest improvements based on findings. 2.5% of local residents were sampled and 1739 were chosen as subjects. Knowledge, attitude, satisfaction and others for TKM public health service were examined. TKM treatment service was most widely utilized(13.2%), followed by CVA prevention program(5.2%). For satisfaction level, CVA prevention program showed highest satisfaction(73.3%), closely followed by (Qi-gong program 63%). In general, awareness and utilization of TKM public health service were low but compensated by high satisfaction level. More active promotion and development of community specific programs should become available in the future.

The experiments were undertaken to evaluate the effects of herbal medicine, Bojungiggitang and Gwibitang in pregnant rats and their fetuses. Female Sprague-Dawley rats were orally administered with the Bojungiggitang and Gwibitang at dose of 5ml/kg/day for 20 days. Pregnant rats were sacrificed at 20th day of gestation, and the internal and reproductive organs. Approximately live fetuses in the 20th day of gestation were randomly selected and fixed in 95% ethanol. To observe skeletal malformations, fetuses were stained with alcian blue and alizarin red S. Maternal body weights of Bojungiggitang and Gwibitang treated group has a tendency to increase compared to that of control group. There were no significant differences in internal and reproductive organs. There were no significant changes between two groups in blood chemistry and hematological values. There were no significant changes in number of corpus luteum, implantation and live fetuses. But Bojungiggitang and Gwibitang administered group showed higher implantation rate than the control group. Also, Bojungiggitang and Gwibitang administered groups showed lower early resorption rate than the control group. And Gwibitang had the higher value in all the other groups in all items. From the sex ratio, the number of females were larger than the number of males in the control group, and more males than females in Gwibitang administered group. Neonatal body weight and the number of fetus of Bojungiggitang and Gwibitang group were higher than that of control group. The fetuses of dams treated with Bojungiggitang and Gwibitang did not show external malformation. Vertebral and sternal variations were observed in Bojungiggitang and Gwibitang administered group compared to the control group. Those variations were insignificant. There were no significant changes in number of ribs, cervical, thoracic, lumbar, sacral and caudal vertebras. From these results, it can be concluded that Bojungiggitang and Gwibitang showed no toxic effects on maternal body weight and the number of live fetuses. There were no significant changes in organ weight, hematological data, and reproductive organs. Although skeletal variations were shown in vertebra and sternum, Bojungiggitang, Gwibitang were shown insignificant changes in bone malformation.

Oxidative stress is one of the major reasons for brain aging and neurodegeneration. Ethanol and acetaldehyde increase the levle of oxidative stress in brain tissue resulting in aging and neurodegeneration related alcoholic dementia. Ginkgo biloba extracts are used as therapeutic and preventive agent for dementia. Here, it was investigated whether Ginkgo biloba extract show the effectiveness against ethanol- and acetaldehyde-induced oxidative stress in rat brain. Ethanol and acetaldehyde increased the level of oxidative stress by about 35% to 50% in rat brain tissue. However, Ginkgo biloba extracts reduced the level of ethanol- and acetaldehyde-induced oxidative stress. This result might reveal the link between the effectiveness of Ginkgo biloba extracts on oxidative stress and its effectiveness on alcoholic dementia.

From the sex ratio, number of females, bigger than number of males in the control group, and more males than females in Yugmijihwangtang administered group(p<0.05).

경성 실시간 작업을 위한 Pre-scheduler 구현

최정현(Jung-hyun Choi),조선동(Sun-dong Cho),한상철(Sangchul Han) 한국정보과학회 2010 한국정보과학회 학술발표논문집 Vol.37 No.2B

Pre-scheduling은 고전적인 정적 스케줄링(static scheduling)을 스케줄러 조합(scheduler composition)의 문맥으로 확장한 것이다. Pre-scheduling에서는 자원의 공급률이 일정하지 않다고 가정하며, pre-scheduler는 주어진 자원 공급계약(supply contract)에 대한 경성 실시간(hard real-time) 주기작업(periodic job)의 정적 스케줄, 즉 pre-schedule을 생성한다. 본 논문은 pre-scheduler의 구현 방안을 제시한다. 제시한 구현 방안은 pre-scheduling의 정의에 잘 부합하며, 복잡한 알고리즘을 직관적이고 간결하게 구현하여, 다양한 시스템에 쉽게 통합할 수 있다.
