First case, a one-year-old female Shih Tzu weighing 3 kg with closed transverse fractures of bilateral mandibular body between 2nd and 3rd premolar teeth were treated surgically with bone plates and screws, and cranial luxation of temporomandibular joints were reduced to closed method. Second case, a 8.4 years old male Yorkshire terrier weighing 2.6 kg with closed transverse/oblique fractures of bilateral mandibular body between premolar and molar teeth were treated surgically with bone plates and screws. Radiographic examination revealed that the fractures in two cases fixed well and temporomandibular joint was stabilized. One month after operation, jaw activity was excellent and malocclusion wasn't observed.

The study suggests the possibility of using internet of things for a dietary intake survey. The development scenario of the dietary intake survey was composed of a weighing sensor for measuring food weight, bluetooth module for communicating through smart-phones, and smart-phone application. The weighing sensor attached to the bottom of utensils was designed to measure the weight of initial food & food eaten, and the results were transmitted to the smart-phone through the bluetooth module. The exclusive application in the smart-phone displayed the results of the amount of food intake, calorie intake, and eating rate. Through this system, subjects could continuously monitor their dietary intake & eating rate and recognize their actual eating environment, which leads to prevent overconsumption of food intake & form balanced eating habits. Based on this system, we need to consolidate and develop a weight control program.

The diverter system is a key component in achieving a high accuracy liquid flow rate standard using a static gravimetric system with a flying start and stop method. The diverter is a moving device used to direct flow alternately along its normal course(by pass) or towards the weighing tank. The time needed for collection into the weighing tank is measured using a timer. So it is important to the diversion period is sufficiently fast and triggering point of timer which is determined the filling time. On this studies show that uncertainty of diverter system for changing diversion speed and triggering point was estimated in accordance with Guide to The Expression of Uncertainty in Measurement(ISO).

The FEM technique was applied to simulate the change of stress characteristics for various structural parameters and loading positions of the load cell. The output voltage of the load cell was then computed to compare with the manufactured load cell. The tendency of the stress variations of the load cell was well agreed with the basic formula of the single fixed. beam. Also, the stress characteristics according to the change of loading positions showed respective featured results as different structure. The calculated output voltages of the load cell were very close to those of the real manufactured ones.

A female, 14-year-old mixed dog weighing 4 kg and a female,8-year-old schnauzer dog weighing 6 kg showing vaginal discharges and vomiting for a few weeks were examined for the preoperative check of anterior cruciate ligament rupture and the recheck after the surgery of nephrectomy. There were no distinct abnormal signs except for the increased CBC at schnauzer dog on blood chemistry analysis. Radiographic and ultrasonographic findings were a large abdominal mass and a cyst-like hypoechogenic or anechogenic cavitary lesion on the ovary region. These findings were consistent with an ovarian cyst. Thereafter highly suspected ovarian cysts by diagnostic imaging were supported by high estrogen concentration on hormonal assay and the results of Pathologic examination as the unilateral ovarian cysts with secondary pyometra.

A female 8-year-old Pug weighing 7.3 kg and a female 10-year-old Maltese dog weighing 3.5 kg showing anorexia and vomiting for a few weeks were referred to Veterinary Medical leaching Hospital, Seoul National University. Radiographic findings were an enlarged right kidney in a pug dog and a radiopaque material on the right ureteral region lateral to the third lumbar vertebrae with indefinite right kidney contour in a Maltese dog, repectively. Excretory urography performed in a Pug dog revealed a poor opacified enlarged right kidney with absent of pelvic recesses and pelvic dilation with proximal ureteral dilation on contralateral kidney. Ultrasonographic findings were enlarged kidney with dilated pelvis and echogenic sediment within the medulla in both dogs and especially an engorged proximal ureter and a thin rim of functional renal tissue remains in a Maltese dog. Those diagnostic findings indicated high possibility of pyelonephritis and these were confirmed by pathologic examination. Radiography and ultrasonography, although not giving final diagnosis for pyelonephritis, are useful for assessment and diagnosis of pyelonephritis.

Prompt neutron lifetime calculations have been performed for the NIRR-1 reactor HEU and LEU cores using the 1/v insertion and the Adjoint flux weighing methods. Results of calculations obtained for the HEU and LEU cores are respectively $57.3{\pm}0.8$ and $47.5{\pm}0.7$ for the 1/v insertion and $56.9{\pm}0.3$ and $46.3{\pm}0.5$ for the Adjoint flux. There is a good agreement seen between the two methods for both cores. The prompt neutron lifetime was observed to be shorter in the LEU than for the HEU as expected. However, the Adjoint flux weighing method seemed to be the easiest method in calculating the prompt neutron lifetime for NIRR-1.

In this study, in conjunction with a SIMULINK program based on system modeling of a voice-coil-actuator (VCA)-driven balancing scale, a proportional-integral-derivative control algorithm is implemented, and weighing characteristics are investigated through experiments and simulations. The extent to which the back electromotive force induced in the VCA-driven circuit and the magnetic damping induced by the coil wound bobbin of VCA affect the weighing speed is also investigated.

This study presents an algorithm and related techniques which could satisfy the important properties of check weighers and conveyor scales. The algorithm of Recursive Least Squares Regression is described for te weighing system simulated as a dynamic model of the second order. Using the model and the algorithm, model parameters and then the mass being weighed can be determined from the step input. The performance of the algorithm is illustrated in digital simulation. Discussions are extended to the development of fast converging algorithm. It turns out that the algorithm shows several desirable features suitable for microcomputer assisted real-time signal processing, which are high precision and stability in noisy environment.
