As fat consumption has increased in Korea , serum cholesterol concentrations have risen and the prevalence of atherosclerosis increased. The aim of the present study was to investigate the association among apolipoprotein E (Apo E) phenotypes, dietary fat consumption, plasma lipoprotein levels and fatty acid compositions of red blood cells in young healthy women. Seventy-one percent of participants had Apo E3/3, 14.9 percent had ApoE3/2 , 11.8% had Apo E4/3 and 1.2% had Apo E4.2. The subjects daily consumed approximately 1760kcal containing 29 energy % of fat. The ratio of polyunsaturated fat to saturated fat in a diet was 0. 73 . There were no significant differences of nutrient intakes according to Apo E phenotypes. Total cholesterol concentrations of subjects averaged approximately 160mg/dl , but 12 percent of them had over 200mg/dl, which is higher than the range recommended by the National Cholesterol Deucation Program. Notably, most subjects with 210mg/dl had Apo E4 isoforms. Subjects with Apo E4 isoforms had significantly higher total and LDL-cholesterol concentrations than those with Apo E3/2. Also subjects carrying Apo E4 isoforms tended to accumulated more fat in the body. Their BMI , WHR and arm fat area appeared to be how can arm fat area be greater no you mean grater, please check work vsage than subjects with Apo E3 isoforms, but not significantly. Fat intakes slightly influenced serum cholesterol levels. Myristic aicd intakes were positively correlated to serum total and LDL-choelsterol levels. Polyunsaturated fatty acid intakes were negatively correlated to serum total choelsterollevels. The results of 소냐 study suggest that , people with Apo E4 isoforms need to prevent the raising of serum total and LDL -cholesterol concentrations by reducing calorie and fat intakes and by maintaining a normal weight.

We conducted an analysis of a selected region from the FCRAO $^{12}CO$ Outer Galaxy Survey. The selected region is located between galactic longitude $117^{\circ}$ and $124^{\circ}$ with the velocity of -23 km $s^{-1}. Molecular clouds in this region show a peculiar velocity field, protruding from the Local Arm population. The selected region is divided into 7 clouds by spatial location. Though we were not able to identify the direct driving source for peculiar velocity of our target region, we find that there are several internal YSOs or star forming activities; there are many associated sources like an outflows, a high-mass protostellar candidate and $H_2O$ maser sources. We attribute the driving energy source to older generation of episodic star formation. Masses of main clouds(cloud 1-4) estimated using a conversion factor from $^{12}CO$ luminosity are larger than $10^4M_{\odot}$. Other components have a small mass as about $10^3M_{\odot}$. Among main clouds, cloud 2 and 4 seem to be marginally gravitational bound systems as their ratio of $M_{CO}$ to $M_{VIR}$ is about $2{\sim}3$, and the internal velocity dispersion is larger than the centroid velocity dispersion. Total mass estimated using a conversion factor from $^{12}CO$ luminosity is $7.9{\times}10^4M_{\odot}$.

Purpose: There are various methods proposed for the evaluation of the hindfoot alignment. However, due to structural calcaneus variances between patients, it is hard to assess this alignment definitively. Thus, this study proposes a new method for evaluating of the hindfoot alignment and its comparisons to the existing current methods. Materials and Methods: This study includes simple weight bearing hindfoot coronal view radiographs of 120 patients, taken between the time period of March 2008 to November 2009. Among the 120 patients, there was a 1:1 ratio of male to female with an average age of 40. The newly proposed method for evaluating this alignment is to draw a moment arm from the point where the sustentaculum tali meets the medial calcaneus border to the most prominent aspect of the lateral process of the calcaneal tuberosity. The angle produced via the intersection of this moment arm to the mid-longitudinal axis of the tibia is found and used to evaluate the hindfoot alignment. The inter and intra-observer reliability was evaluated using the coefficient of intraclass correlation. This study also investigates the comparisons between the newly proposed method to the traditionally used Saltzman et al hindfoot alignment evaluating technique. Results: The newly proposed method has higher inter and intra-observer reliability than the existing traditional Saltzman et al technique. Conclusion: This new method is recommended over the traditionally used Saltzman et al technique as it has a stronger confidence level and is appropriate for assessing hindfoot alignment in simple radiographs.

This study analyzes the body characteristics of Korean obese women using 2004 Size Korea data. For selecting the obesity sample, 7 obesity judgment indices were chosen from previous clothing-related studies. A total of 636 females defined as "obese" by 5 out of 7 indices were selected as subjects for this study. 54 body measurements and obesity judgment indices were used. First, the subjects had a BMI 27.11, R$\ddot{o}$hrer index 1.76, Vervaeck index 104.77, Relative weight 133.00, and WHR 0.90. In the case of the distribution by age groups, the twenties were 6.4% of the entire subjects, the thirties were 18.2%, the forties were 16.4%, the fifties were 37.4%, and the sixties were 21.5%. The result of the ANOVAs (divided into 5 age groups) showed significant differences in 41 measurement items except for bust circumference, waist length front, and all of obesity judgment indices. Second, according to the ANOVAs among stature groups divided by 5cm pitches there are significant differences in all measurements except for bust circumference. The results of the ANOVAs among bust circumference groups divided by 5cm pitches show that significant differences were observed in all measurements except four measurement items (including body rise). According to the ANOVAs among the waist circumference groups divided by 5cm pitches, there are no significant differences in all height measurements and shoulder length, waist to hip length, and crotch length. It is confirmed that stature and bust circumference have a deep relationship with measurements other than waist circumference. Third, as the factor analysis were conducted using 39 measurement items to extract the body characteristics of obese women Factor 1 is "circumference measurements & obesity judgment indices," Factor 2 is "heights & arm-related lengths," and Factor 3 is "size and ratio of waist circumference & hip circumference." Factor 4 was "lengths in upper body," Factor 5 was "back width in upper body," Factor 6 was "side neck point to bust & bust circumference," Factor 7 was "length in lower body & arm circumferences," and Factor 8 was "neck base circumference & front widths in upper body." These 8 factors explained 76.54% of the total variance.

This study aimed to provide basic data for establishing a sizing system for menswear by investigating body size changes and body shapes in adult men in their 30s to 50s. Data on 52 different upper body categories collected from 4,314 people during the 5-7th Size Korea surveys were analyzed. The waist height, hip height, torso and arm lengths, and torso and upper limb circumferences increased while the arm joint sizes decreased. According to factor analysis, factors 1 and 2 referred to 'the horizontal size of the upper body and limbs' and the 'torso height and upper limb length', respectively, while factors 3 and 4 represented 'shoulder size' and 'upper body length' respectively. In clustering analysis, types 1 and 2 were 'short and fat' and 'tall and thin,' respectively, while types 3 and 4 represented 'tallest and chubby' and 'shortest and small' respectively. Torso length increased in the 30 to 40s in type 1 while torso circumference increased in the 30s and late 40s in type 2. In type 3, shoulders got bigger in the 30s. In type 4, torso circumference increased in the early 30s, and torso length increased in the late 40s. 'Thin' was a typical body shape in the early 30s. Among early 40s men, distribution evolved from 'small' to 'thin.' In the late 40s, while the percentage of 'small' decreased, the ratio of 'obese' increased. In the 50s, 'small' was the most common.

This study aimed to identify and compare the characteristics of Elymus humidus on common wheat (Triticum aestivum L. cv. Chinse Spring, CS). The seed length, width, height, and weight of E. humidus were smaller than those of the CS. In particular, the germination rate of E. humidus was substantially lower than that of CS. In the anatomical dissection of the leaf, E. humidus showed a considerably different xylem diameter of the main vascular bundle in the main vein; however, there was no difference in the phloem of the main vascular bundle compared with the xylem and phloem of the main vascular bundle in the main vein of CS, although E. humidus showed a leaf structure similar to that of CS. In addition, E. humidus had a thinner epidermis than that of CS. Regarding stomatal traits, E. humidus showed a graminoid stomata type similar to that of CS. On the adaxial and abaxial sides, the density, length, and width of the stomata in E. humidus were smaller than those in CS, whereas the distance between stomata in E. humidus was greater than that in CS. The chromosomes of E. humidus were classified as long and short based on their respective lengths. Long chromosomes were classified based on the ratio of the long arm to the short arm e.g., 1:1 or 2:1. Short chromosomes showed the same trend and some short chromosomes were microsatellites. To evaluate genetic diversity, 38 barley EST markers with polymorphisms between E. humidus and CS were selected from 236 barley EST markers.

Objectives: This study was to evaluate the effectiveness and safety of Bojungikgi-tang for lung cancer patients with anorexia. Methods: This was a single-arm, open-label, and single-center trial, and suitable participants took Bojungikgi-tang (Buzhongyiqi-tang in Chinese, Hochuekki-to in Japanese) three times a day before or between meals for six weeks (42 days). After registration of clinical trials (visit 2), they visited the hospital every three weeks (visits 3 and 4) and measured or tested the effectiveness or safety evaluation variables to analyze the results. The primary outcome was the anorexia/cachexia subscale (A/CS) of functional assessment of anorexia/cachexia therapy (FAACT) score. Results: Seventeen lung cancer patients were included in the intention-to-treat (ITT) analysis. Lung cancer patients had higher A/CS of FAACT scores after six weeks of Bojungikgi-tang administration compared to that at the baseline. This was not significant four lung cancer (p=0.1668). In the secondary outcomes, the visual analog scale (VAS) score of anorexia decreased significantly (p=0.0009), and the CD4/CD8 ratio (p=0.0396) and CD4 levels (p=0.0345) significantly increased after six weeks of treatment. No serious adverse events were reported with Bojungikgi-tang in lung cancer patients. Conclusions: Bojungikgi-tang can be an effective and safe treatment for anorexia in lung cancer patients undergoing chemotherapy.

Using the design parameters of multi-joint manipulator, worspace of the manipulator were evaluated analytically, and the relation between such design parameters and nonlinearity of the manipulator were presented dynamically. The ratio of the volumes of a manipulator's workspace to the cube of its total link length presents a kinematic performance index [NVI] for the manipullator. It is possible to geometrically represent the manipulator dynamics with the generalized inertia ellipsoid (GIE). The relation between the GIE configuration and the characteristics of manipulator dynamics was analysed in terms of inertia and nonlinear forces (Coliolis and centrifugal forces). The nonlinearity caused by the change of the GIE configuration were affected by the difference between the major and minor axes length of the GIE. The results of this investigationare applied to the optimal design of the manipulator.

In the field of prosthesis arm control, the pattern classification of the EMG signal is a required basis process and also the estimation of force from collected EMG data is another necessary duty. But unfortunately, what we've got is not real force but an EMG signal which contains the information of force. This is the reason why we estimate the force from the EMG data. In this paper, when we handle the EMG signal to estimate the force, spatial prewhitening process is applied from which the spatial correlation between the channels are removed. And after the orthogonal transformation which is used in the force estimation process, the transformed signal Is inputed into the probabilistic model for pattern classification. To verify the different results of the multiple channels, SNR(signal to noise ratio) function is introduced.
