Indicators to quantitatively evaluate the body function may help to optimize the effectiveness of rehabilitation therapy for stroke patients. In this study, we analyzed the body composition in the paretic and nonparetic regions of stroke patients with hemiplegia caused by cerebral hemorrhage (7 cases) and cerebral infarction (13 cases) using multifrequency bioelectrical impedance. Specifically, we considered fat mass (FM), fat-free mass (FFM), FFMI index (FFMI), FM/FFM relation, body cell mass (BCM), basal metabolic rate (BMR), and BMR/FFM relation to evaluate the bodily function in the paretic and nonparetic regions. These values showed considerable differences according to grades determined by the stroke causes and the paralysis status. In the paretic regions, the FFM, FFMI, BCM, and BMR were low and the FM was high. In contrast, the nonparetic regions showed a high FFM and low FM. Furthermore, the paretic and nonparetic regions of all patients suitably fit a linear relation (slope: 22.17 kcal/day/kg) between BMR and FFM. Therefore, bio-electrical impedance measurements can be very useful to quantitatively assess paretic and nonparetic regions in hemiplegic stroke patients.

Objectives : This study was aimed to investigate the change of the reduction in body weight and the change of body composition after fasting therapy, Chulsikyopub, which was put into practice in Dept. of oriental rehabilitation medicine at Kyung Hee oriental hospital. Method : We measured body weight, body composition, and the degree of obesity 2 weeks after fasting therapy and 10 weeks after fasting therapy with body composition analyzer(Inbody 2.0). Statistical comparisons between pre-therapy group and post-therpay group were done by paired t-test and Wilcoxon's signed rank test. Results : 2 weeks after fasting therapy, body weight was decreased 7.33kg(9.18%), body fat was decreased 2.47Kg(7.24%), muscle weight was decreased 4.66kg(11.37%), body fat ratio was increased 1.08%, and body metabolic rate(BMR) was decreased 118.23kcal(8.22%). 10 weeks after fasting therapy, each of body weight and fat was decreased 10.4Kg, muscle weight was increased 0.3Kg(0.7%), body fat ratio was decreased 7.9%, and BMR was increased 6.8Kcal(0.47%). But muscle weight and BMR did not satisfy statistical significance. Conclusions : fasting therapy for 10 weeks reduced body weight and body fat statistically significant without loss of muscle weight and BMR.

Two key data areas of the integrated production database in computer-integrated manufacturing (CIM) systems are the product structure in the forms of bills of material(BOM) and the process structure in the forms of routings. The great majority of existing information systems regard the BOM and routing as two separate data entities, possibly with some degree of cross-referencing. This paper proposes new information structure called the bills of material and routings(BMR) that logically integrates the BOM and routings for the CIM systems in ship production. The characteristics of ship production are described as: 1) make-to-order production type, 2) combined manufacturing principles (workshop production and construction site production), 3) significant overlapping of design, planning and manufacturing, 4) very long order throughput time, 5) complex product structure and production process. The proposed BMR systematically manages ail parts and operations data needed ship production considering characteristics of ship production. Also, the BMR situated on the integrated production database more efficiently supports interface between engineering and production functions, and integrates a wide variety of functions within production such as production planning, process planning, operation scheduling, material planning, costing etc., and simplifies information flow between sub-systems in CIM systems.

This paper examines the effects of the partial solar eclipse of 22 July 2009 across the Korean peninsular on surface temperature and ozone concentrations in over the Busan metropolitan region (BMR). The observed data in the BMR demonstrated that the solar eclipse phenomenon clearly affects the surface ozone concentration as well as the air temperature. The decrease in temperature ranging from 1.2 to $5.4^{\circ}C$ was observed at 11 meteorological sites during the eclipse as a consequence of the solar radiation decrease. A large temperature drop exceeding $4^{\circ}C$ was observed at most area (8 sites) of the BMR. Significant ozone drop (18~29 ppb) was also observed during the eclipse mainly due to the decreased efficiency of the photochemical ozone formation. The ozone concentration started to decrease at approximately 1 to 2 hours after the event and reached its minimum value for a half hour to 2 hours after maximum eclipse. The rate of ozone fall ranged between 0.18 and 0.49 ppb/min. The comparison between ozone measurements and the expected values derived from the fitted curve analysis showed that the maximum drop in ozone concentrations occurred at noon or 1 PM and was pronounced at industrial areas.

오늘날 비만인구가 증가함에 따라서 비만을 관리하고 모니터링하는 시스템 개발의 필요성이 증대되고 있다. 그러나 대부분의 모니터링 시스템은 사용자의 신장이나 체중의 정보만을 가지고 계산하여 보여주는 역할만 하기 때문에 사용자가 운동에 대한 계획을 설계할 시에 효율성이 낮은 문제점이 있었다. 본 논문에서는 사용자의 BMI의 수치를 그래프로 나타내고, BMR수치의 등급을 나누어 사용자가 자신에 대해 이해하기 쉽게 하였다. 또한 사용자가 사용한 운동기구의 사용한 회수와 일간 소모한 Kcal를 보여줌으로써 운동 계획을 설계하는데 효율적인 웹 기반 모니터링 시스템을 연구한다.

The objectives of this study were to determine whether older Americans would provide valid energy intake information using a 24-hr recall method and to determine which characteristics were predictive of under-report of energy intake. We conducted 24-hour recalls on 83 male and 105 female community-dwelling older adults(66-87y) in the USA to assess energy(EI) and nutrient intakes. Basal metabolic rate(BMR) was calculated from age-and gender-specific equations of Schofield. Under-reporting was defined a priori as EI : BMR<0.9. Subjects volunteered demographic information, underwent depression and cognition exams, and completed a Level II Nutrition Risk Screen. Differences between under- and adequate-reporters were assessed using t-tests for characteristics and macro-nutrient profile. Stepwise regression analyses were used to predict under-reporting status. Under-reporting of EI occurred in 34% of the sample. Neither geriatric depression scale(GDS) score, nor self-reported weight loss were related to under-reporting. On average, under-reporters had higher body mass indices. The most significant variables for the main effect to predict the ratio of energy intake to estimated basal metabolic rate(EI : BMRest) were BMI and age. Using a standard cut-off of 76% of the recommended dietary allowances for Americans, under-reporters were consistently more likely to be classified as having inadequate nutrient, as well as energy, intakes.
