An abnormal Korean native cow of six years old with extra legs was observed macroscopically and radiographically. The results were summarized as follows; 1. External features included two normal forelimbs and hindlimbs, and two extra forelimbs which were underdeveloped. The extra forelimbs of different length attached laterally to the cranial regions of neck on right scapula. 2. The large extra forelimb had scapular meromelia. It consisted of underdeveloped humerus, antebrachial skeleton, several carpal bones, metacapal bone(MC3+4) and two digitis with each pairs of hoof and a rudimentary hoof of dewclaw. 3.

The distribution of portal veins within the liver in 30 Korean native cattle were observed. Vinylite solution was injected into portal veins of eighteen specimens for cast preparation. The angiography was prepared in twelve specimens by injecting 30% barium sulfate solution into portal veins, and then radiographed on a X-ray apparatus(Shimadzu 800MA 120Kvp). The results were summarized as follow: 1. The Vena portae was divided immediately upon entering the liver into a very short Truncus dexter venae portae($14.75{\pm}4.86$ : 6.9~23.1mm) and a long Truncus sinister venae portae($94.16{\pm}9.62$ : 110~150mm). 2. The Truncus sinister venae portae runs of first in the long axis of the liver from the Porta hepatis toward the left lobe. At the boundary between the quadrate and left lobes it bends sharply 50 to 80 degrees toward the Incisura ligamentum teretis, and after a course of 36. 5 to 54.mm between the quadrate and left lobes, ends abruptly. The Truncus sinister venae portae is divided for description into the Pars transversa, from the Porta hepatis to the flexure, and the Pars umbilicalis, from the flexure to the end. 3. The branches of Venae portae were Ramus ventralis lobi sinistri, Ramus intermedius lobi sinistri, Ramus dorsalis lobi sinistri, Ramus lobi quadratii, Ramus ventralis lobi dextri, Ramus intermedius lobi dextri, Ramus dorsalis lobi dextri, Rami processus caudatorum and Rami processus papillarum. 4. The Ramus intermedius lobi sinistri was arised from the left surface of the Pars umbilicalis, and was origined on the common trunk with Ramus dorsalis lobi sinistri(3 cases, 10%) or Ramus ventralis lobi sinistri(3 cases, 10%). 5. The Rami lobi quadratii consisted of the vein(15 cases, 50%) or two veins(15 cases, 50%), and was observed on the arched-shaped at 2 cases (6.6%) of the liver. 6. The Rami processus caudatorum consisted of one vein(28 cases, 93.3%) or two veins(2 cases, 6.6%). The former were formed common trunk with R, dorsalis lobi dextri(7 cases, 23.3%) or R. ventralis lobi dextri (2 cases, 6.6%). 7. The Rami processus papillarum were arised from the dorsal border of Pars transversa, and also gave off many small branches supplied papillary process of the caudate lobe. 8. The anastomosis on the branches of Vena portae was observed in the intralobar and interlobar areas. 9. The Truncus dexter venae portae and Truncus sinister venae were ramified many secondary branches that were radiated within the liver. 10. On the diaphragmatic surface, small vessels of the portal veins were observed, while there were big ones on the visceral surface. 11. The ramified angles at Ramus dorsalis lobi dextri, Rami processus papillarum, Ramus dorsalis lobi sinistri, Ramus intermedius lobi sinistri, Ramus ventralis lobi sinistri, Rami lobi quadratii, Rami processus caudatorum, Ramus ventralis lobi dextri and Ramus intermedius were 10~50, 70~110, 100~150, 140~170, 185~220, 270~330, 240~300, 270~320 and 340~10 degrees, respectively.

A case of schistosomus reflexes in Korean native female calf was observed macroscopically and radiographically. The results were summarized as follows. 1. The abdominal visceral organs were exposed. 2. The vertebral column bent laterally to the left, and the sacrum approached to the cranium by reflected caudal lumber vertebrae, presenting S-shaped lateral twisting of the vertebrae. 3. The right ribs reflected laterally and dorso-cranially from the 7th rib to 13th rib. The left ribs bent caudally from 8th rib to 13th rib. 4. The length of rudimentary 6th right rib was one half of normal size and the 7th right rib was one third. 5. The sternum was bifid split from the fourth sternebra through the xyphoid cartilage. 6. The diaphragm was intact and thoracic cavity was reduced in size. The lung and heart severely deformed in shape and size. 7. The liver markedly deformed in shape and thickness. 8. The pelvic cavity was reduced in size by compression laterally to the left. 9. The uterus horn, ovary, urinary bladder, and urethra were severely deformed in the shape and position.

A female Holstein calf with five legs and two tails was examined macroscopically and radiographically. The external feature included two normal forelimbs, two normal hindlimbs, a normal tail and each of underdeveloped extra hindlimb and tail, which was attached to the pelvic region. The extra hindlimb consisted of an underdeveloped femur, crural meromelia, duplicated calcaneous, partially duplicated metatarsal bone, three rows of digits with hoofs. This extra hindlimb was connected to an extra os coxa. The cervical and thoracic vertebrae were fused partially. The lumbar, sacral and coccygeal vertebrae were duplicated.

A female Korean native calf with diprosopus was examined macroscopically and radiographically. Anterior head duplication (diprosopus) was observed and all structures caudal to it were normal. She had two complete mouths, four eyes and three ears. Single tongue was present in each oral cavity. The two tongues were joined at their base just posterior to the single epiglottis. Both oral cavities led jointly into a common pharynx and one esophagus. One laryngeal cavity communicated with one common trachea. The lower jaws were immobile because of overlapping mandibular rami. The atlas was complete, and two anterior articular cavities articulated with the lateral condyles of the occipital bones of each skull. The cerebrums were fused each other at their caudal portion, and the giri and sulci were underdeveloped. The cerebellums were also completely fused, and they had not characteristic appearance of the vermis. The spinal cord showed normal appearance.

The inter-conversion between different control laws in flight has a lot of risk. The SWM(Switching Mechanism) including logic and stand-by mode is designed to analyze the transient response of aircraft during inter-conversion between different control laws, based on the in-house software for non-real-time and real-time simulation. The SWM applies the fader logic of TFS(Transient Free Switch) to minimize the transient response of an aircraft during the inter-conversion, and applies the reset '0' type of the stand-by mode to prevent surface saturation due to integrator effect in the disengaged flight control law. The transition time is also important to minimize the objectionable transient response in the inter-conversion, as well as the transition control law design. This paper addresses the results of non-real-time simulation for the characteristics of transient response to different transition time to select the adequate transient time, and the real-time pilot evaluation, using SSWM(Software Switching Mechanism) and HSWM(Hardware Switching Mechanism), which is met for Level 1 flying qualities and assures safety of flight.
