This study was carried out to compare the agronomic characteristics, forage yield, and feed value of nine sorghum ${\times}$ sudangrass hybrids at paddy field cultivation. The nine recommended sorghum ${\times}$ sudangrass hybrids used in this study were P877F, Cow pow, Turbo gold, Maxi graze, Jumbo, G7, Sweet home, Honey chew BMR and Green star. Plant height, leaf number, stem diameter, and stem hardness were higher in Jumbo than other varieties (P<0.01). Sugar content (brix) was higher in order of P877F > Sweet home > maxi graze > Green star > Cow pow > G7 (P<0.01). Fresh (86,199kg/ha) and dry matter yield (16,206 kg/ha) of Jumbo were higher than other varieties (P<0.01). Crude protein was the highest in Maxi graze (6.5%), but crude fat was the highest in Honey chew BMR as 2.1% (P<0.01). NDF and ADF of Jumbo and G7 were higher than other varieties (P<0.01). TDN was higher in order of Maxi graze > Sweet home > P877F > Honey chew BMR > Green star, but no significant differences were found among the varieties. Minerals were the highest in Cow pow (15,020.5 mg/kg), and Sweet home (6,222.6 mg/kg) was the lowest as compared to other varieties (P<0.01). Total amino acids were higher in order of Maxi graze > Sweet home > Turbo gold > Honey chew BMR > Jumbo (P<0.01). Crude protein yield and crude fat yield were the highest in Turbo gold (814.6 kg/ha) and Honey chew BMR (309.8kg/ha), respectively (P<0.01). Mineral yield was the highest in Cow pow as 207.6 kg/ha (P<0.01). Amino acid yield (592.2 kg/ha) and TDN yield (10,194 kg/ha) were the highest in Sweet home. Based on the above results, sorghum ${\times}$ sudangrass hybrid varieties should be selected on the basis of the purpose of use.

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.

Existing exercise management systems provided exercise information to the user. However, there is a problem that the accuracy is low due to the absence of an algorithm for analyzing the user's body information and providing information. In this paper, BMI(Body Mass Index) and BMR(Basal Metabolic Rate) values are analyzed to analyze user's body information. It also recommends exercise intensity and momentum to the user and graphs the history of the exercise device that the user has used. Through this, it is considered that the information corresponding to the user's body can be provided and the exercise management can be carried out.

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.
