  • The purpose of this study was to investigate the possible causal factors of obesity in women with child-bearing experiences in effects to provide optimal information for the prevention and/or treatment of obesity. Sventy one women with child-bearing experiences were divided into five groups based on the degree of obesity by BROCA method ; normal weight, overweight, and obesity which was further divided into three groups of light, moderate, and sever obesity. Various anthropomnetric measurements, overall eating habits, and dietery intakes were asessed for each groups. Out of eighteen anthropometric factors asociated with obesity, thirteen measurements were represented to be valid for the diagnosis of obesity. Body fat % which was analyzed by Bioelectrical Impedance fatnee Analyzer were 24.765, 28.05%, and 29.85 for normal, overweight, and obesity group respectively. WHR(waister to hip ratio) or BMI(body mass index) widely used index was also resulted to be valid as a predictor of obesity. Waist circumference which represents abdominal fat mass showed a good correlatin with body fat%. The analysis of dietary intakes suggested that the overintakes of total calorie may not be the only causal factor of obesity, rather the amount of daily protein, fat and carbohydrate intakes or the physical activity level would be more closely related with the prevalence of obesity. Further investigation considering more variety of food composition of diet and the activity level involving larger number of subjects would be needed.

  • The MERIS MCI (Maximum Chlorophyll Index), measuring the radiance peak at 709 nm in water-leaving radiance, indicates the presence of a high surface concentration of chlorophyll ${\underline{a}}$ against a scattering background. The index is high in 'red tide' conditions (intense, visible, surface, plankton blooms), and is also raised when aquatic vegetation is present. A bloom search based on MCI has resulted in detection of a variety of events in Canadian, Antarctic and other waters round the world, as well as detection of extensive areas of pelagic vegetation (Sargassum spp.), previously unreported in the scientific literature. Since June 1 2006, global MCI composite images, at a spatial resolution of 5 km, are being produced daily from all MERIS (daylight) passes of Reduced Resolution (RR) data. The global composites significantly increase the area now being searched for events, though the reduced spatial resolution may cause smaller events to be missed. This paper describes the composites and gives examples of plankton bloom events that they have detected. It also shows how the composites show the effect of the South Atlantic Anomaly, where cosmic rays affect the MERIS instrument.

  • A variety of multimedia applications require multimedia database management systems to manage multimedia data, such as text, image, and video, as well as t support content-based image or video retrieval. In this paper we design and implement a content-based image retrieval system, BADA-IV/I$^2$R(Image Information Retrieval), which is developed based on BADA-IV multimedia database management system. In this system image databases can be efficiently constructed and retrieved with the visual features, such as color, shape, and texture, of image. we extend SQL statements to define image query based on both annotations and visual features of image together. A high-dimensional index structure, called CIR-tree, is also employed in the system to provide an efficient access method to image databases. We show that BADA-IV/I$^2$R provides a flexible way to define query for image retrieval and retrieves image data fast and effectively: the effectiveness and performance of image retrieval are shown by BEP(Bull's Eye Performance) that is used to measure the retrieval effectiveness in MPEG-7 and comparing the performance of CIR-tree with those of X-tree and TV-tree, respectively.

  • SPS(Space Physics Sensor)는 1999년 발사된 다목적 실용 위성 1호(KOMPSAT-I)에 실린 관측 장비로서, 태양 활동 극대기인 2000년 6월부터 2001년 8월까지 지구 이온층에 관한 자료를 지구로 전송하였다. 이 자료 중 때때로 저위도 지역에서 급격한 플라즈마 밀도 증가 현상을 볼 수 있었다. 이러한 현상의 통계적 분포를 살펴본 결과, 지구 자기장이 약한 대서양 지역과 하와이 지역에서 발생 확률이 가장 높으며, 지자기 활동성 지수인 Dst나 태양 활동성을 나타내는 F10.7지수와는 특별한 상관관계가 없다는 사실을 확인할 수 있었다. 밀도 증가 지역 내의 전자 온도 변화는 개별 사건마다 증가, 유지, 또는 감소를 보이고 있으나, 온도가 급격히 감소하는 경우가 지배적이었다.

  • Purpose: The purpose of this study is to provide analysis of physiological, biomechanical responses occurring from the operation to lifting or twist lifting task appears frequently in agricultural work. Methods: This study investigated the changes of physiological factors such as heart rate, heart rate variability (HRV) and biomechanical factors such as physical activity and kinetic analysis in the task of twisting at the waist while lifting. Results: Heart rates changed significantly with the workload. The result indicated that the workload of 2 kg was light intensity work, and the workload of 12 kg was hard intensity work. Physical activity increased as the workload increased both on wrist and waist. Besides, stress index of the worker increased with the workload. Dynamic load to herniated discs was analyzed using inertial sensor, and the angular acceleration and torque increased with the workload. The proposed measurement system can measure the recipient's physiological and physical signals in real-time and analyzed 3-dimensionally according to the variety of work load. Conclusions: The system we propose will be a new method to measure agricultural workers' multi-dimensional signals and analyze various farming tasks.

  • OSA(Obstructive Sleep Apnea) is a condition with repeated obstruction of the upper airway while sleeping. This obstruction of the upper airway may result if sleep-induced physiologic change in muscle activity is superimposed on various structural defects of the upper airway. Macroglossia, micrognathia, retrognathia, and decreased airway lumen have all been implicated in OSA. There are a variety of surgical and nonsurgical treatment modalities currently available for OSA. Recently the uvulopalatopharyngoplasty has achieved widespread use, but success rates vary and long-term effects are still unknown. Current nonsurgical treatment methods can be cumbersome and uncomfortable with variable responses. For this case. we diagnosed as OSA by using polysomnographic analysis and cephalometric analysis, and delivered intraoral removable appliance which is more conservative, reversible and easy to use for patient. And we got results that Apnea Index(AI) decreased from 14.4 to 3.1, Total Respiratory Disturbance Index(Total RDI) decreased from 18.1 to 7.0 and removal of chronic headache in daytime.

  • Food habit forming the basis for a lifetime of food and nutrient intake is established in early childhood and has an effect to the child's growth, sociality, and obesity. A variety of nutrition screening tools exists for assessing the health and nutrition status of children such as the Growth Curve, for determining if growth is appropriate. Body mass index(BMI) as a more reliable index of overweight to prevent childhood obesity, and Nutrition Quotient(NQ) and eating behaviors questionnaire for young children and parents to estimate their nutrient intake adequate or not. Such tools are mainly used by health practitioners, such as doctor and dietitian to provide nutrition intervention services to children at risk, especially and are not easy to use for general parents, who need assessment at any time and at any place. We propose Growth Assistance System for infants and children, which is possible to assess their physical condition, nutritional status, and eating behavior integrated. To be convenient and portable, it is implemented over the smartphone as an application. The system offers the growth charts, the BMI curves, NQ and eating behavior questionnaire to take a monitoring and the functionalities operate well. We hereby expect this system support the normal growth and development of infants and young children. And also support for the health practitioner (dietitians and nutritionists) to take a role in providing nutrition counseling and education to children needing nutrition services.

  • Purpose: This study was done to analyze the trends in excercise-related research in nursing and non nursing research studies published in Korea. Method: Two hundred and ten research studies published in Korea between January, 1990 and December, 2002 were analyzed according to the criteria of methological characteristics, pattern of excercise-related program, and measurement index of exercise effect. Results: There were twice many papers from nursing compared to other fields, and many experimental studies in nursing were done with more variety than in non nursing fields. Aspects of exercise pattern, such as excercise type. duration, and frequency, exercise-intervention pattern, and applying theory were especially included. When patterns of excercise therapy and index of exercise effect were analyzed, each researcher used their own unique excercise contents and intervention patterns(excercise time per week, exercise duration at each time period, excercise, intervention time, and etc). Conclusion: For the importance of exercise therapy to health improvement and the proper suggestion of exercise therapy on the basis of this research, meta-analysis of exercise effect are needed, and with this analysis, intervention patterns of exercise, development of standard exercise therapy, and identification of exercise effects are required.
