  • A validation study has been performed using the Soil and Water Assessment Tool(SWAT) model with data collected for the Neponset River watershed, which includes roughly 130 square miles of land located southwest of Boston. All of this land drains into the Neponset River, and ultimately into Boston Harbor. This paper presents the methodology of a SWAT model. The calculated contribution of the baseflow to the streamflow is far too high whereas the interflow is strongly underestimated. Alternatively, the modified and calibrated model yields far better results for the catchment. The modification allows hydrological processes to be modeled while not restraining the applicability of the model to catchments with other characteristics. For this study, the SWAT 2005 model is used with ArcGIS 9.1 as an interlace, and sensitivity analysis is performed to provide rough estimated values before adjusting sensitive input parameters during calibration period.

  • To decrease the intake of animal fat and cholesterol, changes in the physico-chemical characteristics of pork Boston butts cooked by different methods (boiling, steaming, baking, and frying) were investigated. Cooking weight loss and the drain rates of moisture, lipids, and cholesterol were highest during frying. The pH value increased during all cooking processes tested. The refractive index of meat fat increased markedly upon frying. The hardness, gumminess, and chewiness of meat were notably increased by frying. Springiness was not significantly affected by any cooking process, and cohesiveness was slightly increased by all cooking methods evaluated. The CIE $L^*$ (lightness) value was markedly increased upon steaming, and the CIE $a^*$ (redness) value decreased notably with boiling or steaming. The CIE $b^*$ (yellowness) value decreased slightly with either boiling or steaming, and was slightly increased when baking or frying was used. The fatty acid composition did not significantly change after cooking, except when meat was fried.

  • An increase in senile dementia population has caused social concerns in Korea. The Korean-Boston Naming Test(K-BNT) has been used in assessing naming ability of patients with diffuse brain damage as well as senile dementia. This study was conducted to develop a short from of the K-BNT. to present normative data, and to demonstrate clinical utility of the shortform K-BNT. The participants were 142 healthy elderly adults, ages between 55 and 84, who were sampled in the Seoul-Kyungki area. Twenty patients with mild probable DAT participated in the study. We developed four norms based on education(0∼6 years and more than 6 years) and age(55∼64 and 65∼84 years). The study showed high internal consistency among the items. Further. DAT patients and normal controls showed significant difference in the K-BNT short form scores(F(1, 158) = 23,216, p < .0001). Normative data presented in this study will be useful in evaluating the naming ability of elderly patients in clinical setting.

  • This study understands rockers of today and supplies basic data of design and manufacture studying pattern change of rockers arisen in West, there is the purpose. Also, this study is investigated by dividing theoretical background of rockers, 7 kinds of American traditional rockers and European rockers from 18th century to opening part of 20th century and contemporary rockers since 20th century. The theoretical background and the style of 2 rockers (Windsor rocker, Boston rocker) were investigated to study the stylistic changes of rockers. Originally a rocker was invented by a European farmer around 1700. It developed to a household which equip practicality and comfortablness in the United States than Europe. Early rockers in a primal form appeared in the 1740s in the United States. American early rockers connected skate to established chair bridge. Rockers are deep connection with family's emotion. Rockers can provide playing functions for children and medically treating functions for adults. Windsor Rockers developed by attaching skate is mammy bench and according to shape of back form bow or hoop-back rocker, birdcage rocker, comb-back rocker. Windsor Rockers formed peculiar American tradition of craftsman furniture through structure that have a unique back of a chair and round seat. Boston Rockers were the first chairs made by mass production method. They show a particular shape with S-curve style seat and rectangular crest at the upper part of the back. Often Crests were decorated by stenciled pattern with curled leaves such as rosettes and scrolled designs.

  • The principles for repair of bilateral cleft lip and nasal deformity are 1) symmetry, 2) primary muscular continuity, 3) proper philtral size and shape, 4) formation of the median tubercle and vermilion-cutaneous ridge from lateral labial elements, and 5) primary positioning of the alar cartilages to construct the nasal tip and columella. The authors underscore the essential role of preoperative premaxillary positioning for the synchronous closure of the cleft lip and primary palate, and describe Mulliken's operative technique. We discuss three-dimensional adjustments based on predicted fourth-dimensional changes. In a consecutive series of 50 patients, no revisions were necessary for philtral size or columellar length. Preoperative premaxillary positioning and primary repair of bilateral cleft lip and nasal deformity may impair maxillary growth. Nevertheless, a symmetric nasolabial appearance, rather than emphasis on maxillary growth, is the priority for the child with bilateral cleft lip.

  • PURPOSE. The aim of this study was to determine the influence of long base lengths of a fixed partial denture (FPD) to rotational resistance with variation of vertical wall angulation. MATERIALS AND METHODS. Trigonometric calculations were done to determine the maximum wall angle needed to resist rotational displacement of an experimental-FPD model in 2-dimensional plane. The maximum wall angle calculation determines the greatest taper that resists rotation. Two different axes of rotation were used to test this model with five vertical abutment heights of 3-, 3.5-, 4-, 4.5-, and 5-mm. The two rotational axes were located on the mesial-side of the anterior abutment and the distal-side of the posterior abutment. Rotation of the FPD around the anterior axis was counter-clockwise, Posterior-Anterior (P-A) and clockwise, Anterior-Posterior (A-P) around the distal axis in the sagittal plane. RESULTS. Low levels of vertical wall taper, ${\leq}10-degrees$, were needed to resist rotational displacement in all wall height categories; 2-to-6-degrees is generally considered ideal, with 7-to-10-degrees as favorable to the long axis of the abutment. Rotation around both axes demonstrated that two axial walls of the FPD resisted rotational displacement in each direction. In addition, uneven abutment height combinations required the lowest wall angulations to achieve resistance in this study. CONCLUSION. The vertical height and angulation of FPD abutments, two rotational axes, and the long base lengths all play a role in FPD resistance form.

  • In this Paper, the effect of stage ceiling height on the acoustic characteristics of rectangular concert halls are investigated. To find out the acoustic properties of audience area, A simple Boston Symphony Hall(BSH) model which is typically rectangular shaped was applied for computer simulation. A newly built rectangular concert hall with 400 seats was also chosen for a scale model $(1.2m{\times}0.68m{\times}0.31m)$ study and its computer simulation varing the stage ceiling height and the volume. The results show that RT increased as the stage ceiling was lowered and the difference rate of RT by its variance is from -0.09 to -0.06[sec/m].

  • A six-month-old Boston terrier presented with an extruded penis caudally, incompletely formed preputial sheath, bifid scrotum, retained testicle and deformity of the os penis. On physical examination, the urethral orifice was located on the surface of the perineum and a fibrous band was observed running from the grans to the urethral orifice on the perineum. The dog also had urethritis that was infected by ascending bacteria entering through the contaminated urethral orifice. Corrective surgery was undertaken to excise the external genitalia and retained testicle. The prepuce, penis and retained testicles were successfully excised. After the urethral orifice was cleaned periodically and antibiotics were administrated, recurrent urethritis disappeared. Using this therapeutic regime it is not necessary to reconstruct the anomaly located urethral orifice, if the location of urethral orifice is not the cause of recurrent urethritis and urinary incontinence.

  • This study aimed to determine the effects of breed on meat quality characteristics of porcine Boston butt muscles (M. subscapularis) from three different pig breeds: Landrace×Yorkshire×Duroc (LYD), Berkshire, and Ibérico available in Korean market. Ibérico showed significantly higher fat content, yellowness (CIE b⁎), cooking loss, and lower shear force values than LYD and Berkshire. Moreover, the contents of oleic acid (18:1) and palmitic acid (16:0) were significantly higher in Ibérico breed, but stearic acid (18:0) was higher in LYD. As linoleic acid (18:2) and arachidonic acid (20:4) were higher in Berkshire sows as compared to the other breeds, atherogenicity and thrombogenicity indexes were significantly lower in Berkshire sow. Ibérico had lower the ω-6/ω-3 fatty acids ratio, and higher taurine and free amino acids compared with the others. Ibérico also showed significantly greater lipid oxidation, lower antioxidant capacity, and higher hypoxanthine contents, whereas the Berkshire had higher inosine-5'-monophosphate and lower K-index value as compared to the Ibérico. The breed did not impart any significant effect on the size and density of muscle fibers. Thus, quality characteristics of Boston butt varied from breed to breed, and certain consumer preferences for Ibérico can be explained, in part, by the unique quality characteristics imparted by higher contents of intramuscular fat, oleic acid, and free amino acids.
