Drivers are becoming more fatigued and uncomfortable as traffic densities increase, which can lead to slower reaction time, They then face the danger of traffic accidents due to an inability to cope with frequent shifting, To reduce this risk some drivers prefer automatic transmissions (AT) to manual transmissions (MT), The AT is superior drivability and less shifting shock than the MT, so the market-share of AT is increasing, The AT is controlled by Electronic Control Unit (ECU) to obtain better shifting performance, The Transmission Control Unit (TCU) is a product of higher-value-added, so the companies which have advanced technology (BOSCH, SIEMENS VDO, DELPHI, and etc.) tend to evade technology transfer. As the number of ECU used on a car is increasing gradually (for example, engine management unit, transmission control unit, brake control unit, and powertrain control unit), TCU's performance is expected to be faster and more efficient for organic communication and arithmetic processing between the control systems than the performance of 16bit controller. In this paper, the model of automatic transmission vehicle using MATLAB/Simulink is developed for the hardware in-the-loop simulation with an embedded system. The AT control logic developed is loaded to 32-bit Embedded system platform developed on the basis of Freescale's MPC565, and we execute the Software-in-the-loop simulation (SILS) of AT based on Real Time Operating System (RTOS). These test results show that the developed embedded system can be used as AT control unit.

Drivers are becoming more fatigued and uncomfortable with increase in traffic density, and this condition can lead to slower reaction time. Consequently, they may face the danger of traffic accidents due to their inability to cope with frequent gear shifting. To reduce this risk, some drivers prefer automatic transmission (AT) over manual transmission (MT). The AT offers more superior drivability and less shifting shock than the MT; therefore, the AT market share has been increasing. The AT is controlled by an electronic control unit (ECU), which provides better shifting performance. The transmission control unit (TCU) is a higher-value-added product, so the companies that have advanced technologies end to evade technology transfer. With more cars gradually using the ECU, the TCU is expected to be faster and more efficient for organic communication and arithmetic processing between the control systems than the l6-bit controller. In this paper, the model of an automatic transmission vehicle using MATLAB/Simulink is developed for the Hardware in-the-Loop (HIL) simulation with a 32-bit embedded system, and also the AT control logic for shifting is developed by using MATLAB/Simulink. The developed AT control logic, transformed automatically by real time workshop toolbox, is loaded to a 32-bit embedded system platform based on Freescale"s MPC565. With both vehicle model and 32-bit embedded system platform, we make the HIL simulation system and HIL simulation of AT based on real time operating system (RTOS) is performed. According to the simulation results, the developed HIL simulator will be used for the performance test of embedded system for AT with low cost and effort.

Studies on diagnosis and treatment of tumor . abscess . ulcer in intestinal carbuncle were carried out. The result of studies were summerized as follows: 1. By Nai-Gyung carbuncle-tumor arose from disharmony between nutrient and defensive because of cold, abscess arose from fever victory between cold and fever, ulcer arose from decreasing function of Bi-Kam year. By latter literature Bi-Kam year could be interpreted that spleen stomach was invaded evil influence from unattainable vital force of the earth. 2. Sites of intestinal carbuncle were large intestine, small intestine, intestinal inside or outside between large and small intestine, Intestinal carbuncle was common name of a disease about large intestinal carbuncle, small intestinal carbuncle, pelvic intestinal carbuncle, shrink leg intestinal carbuncle etc.. Pain appeared Chunchu-Hyul in large intestinal carbuncle, and Gwanweon-Hyul in small intestinal carbuncle. 3. On abdominal diagnosis tumor had indistinct pain of Gwanweon Chunchu, edema and heary feeling in low abdomen, no excessive pain by hand press and intestinal boiling sound. In abscess pain descended from right side of low abdomen to huckle, and there was rejection against press, feeling about fever,water sound with flank movement. In ulcer hand approach was difficult since excessive pain diffuse to whole abdomen, and perforating ulcer sometimes caused a serious symptom of umbilical pus. 4. On fecal and urinary diagnosis in tumor urine was yellowish red pollakiuria like gonorrhoea and occasional constipation. In abscess uncomfortable rough pain short red early urine like gonorrhoea appeared during urination, and constipation with stinging pain appeared during defecation. In ulcer red rough pyuria appeared, and stinging and pain with puruloid blood appeared during defecation. 5. On treatment in tumor Daiwhang-Tang Daisenggi-Tang Dangui-Jun by dissipation method, calming down method, interior reliance maturation method, in abscess Mokdan-San Euiiin-Tang Jeokduiin-Tang by the method of water repelling pus discharge, acute breaking, in ulcer Takridanggui-Tang Paljin-Tang Bojungikki-Tang were each used by the method of interior reliance, virulence astriction, supplement vital force and blood, supplement spleen stomach. 6. On treatment patient may have to be careful of excessive moving and suprising anxiety. Abuse of acupuncture and moxibustion made patient worse, misuse of analgesics purgative intestinal irrigation etc. could provoke difficult diagnosis and perforation. So you must treat after exact diagnosis. 7. Prognosis of ease tumor ease abscess ease ulcer and ease astriction was good. If the intestinal carbuncle were not to promote to abscess and ulcer for a long time, its prognosis was bad and it could metastasize to cancer because of dark purple with hardness. So tumor abscess ulcer in intestinal carbuncle may be significant of precancerous lesion.

In an attempt to investigate the current of clinical researches on spleen yang or vital energy deficiency syndrome, the results were as follows. 1. It is possible to occure spleen deficiency syndrome which come from genetic factor. 2. The absorption disturbance in spleen deficiency syndrome can be likely caused by gastrointestinal mucosa injury, disorder of vagus nerve funtion and impairment of excretion of exocrine gland in pancreas. 3. Owing to the failure of tansporting and converting funtion of spleen, minerals, hematogenic substance and nutritional substance are scanty and then imbalanced metabolism state which heat production is decreasing is appeared. 4. By the failure of vital energy and blood growth, decreasement of $O_2$ transportation ability of RBC, disoder of blood coagulation, immune system disturbance which humoral immunity is enhanced and cellular immunity is decreased, are noted. 5. While there is not still an attemt to study the spleen deficiency sydrome in muscle disease or disease of four extremities, but it is likely suggested that spleen-stomach supplyment thereapy is very excellent effect on muscle disease and disease of four extremities.

About Oui-Ga-Sil(胃家實) in order to considerate the contents recorded in Nai-Gyung Sang-Han-Lon and latter literature, definition, etiopathology, syndrome, differential diagnosis, therapy, Prognosis and prevention were classified. And the results were as follows: 1. Oui-Ga(胃家)was a term which indicated the whole digestive system such as stomach, small intestine, large intestine, rectum and anus. Sil(實)could be defined as the peculiar concept pertaining to the acute and last stage which was invaded to inside bowels because of abundance with evil influence. 2. Eliology of Oui-Ga-Sil was abunt gastric fever originally, injured mucus because of mistreatment, the invasion to inside of outside evil influence through meridian. Pathology was the opening and shutting appearance of gastric abundance with intestinal emptiness, and intestinal abundance with gastric emptiness, Oui-Ga-Sil could be occurred because of gastric abundant dryness and splenic humidifying capacity decrease. 3. Symptom of Oui-Ga-Sil was classified as for the sunlight outside syndrome and the inside abundant syndrome. The sunlight outside syndrome was body fever, sweating, no chilling, on the contrary hatred of fever. The chief complaint of inside abundant syndrome was daily fever, talking in delirium, hand and foot sweating, abdominal distention, difficult defection and those could be pertained to sunlight bowel syndrome. 4. Diagnostic views of Oui-Ga-Sil were that pulse was descending abundant large strong and smooth quick, a coated tongue was yellow, deep yellow, old yellow, thick, scorching dry rough or gray black. On abdominal diagnosis, pressing by hand, patient was conscious of pain, excessive pain, rejection against press, impossible press or intermittent abdominal pain and bowel cutting pain without press. 5. Differential diagnosis was that the sunlight of Nai-Gyung-Fever-Theory was outside desease making meridian the prime object, Baik-Ho-Tang syndrome was making figureless abundant fever the pivotal point. And important differential standard of splenic shrink syndrome was that a daily fever, an irritation with fever were not occurred. 6. Theory of Oui-Ga-Sil was that Seng-Gi-Tang classes had been used in attacking downward or making balance, and moxibustion on Jung-Wan, honey boiling induction theory had been also used. Attacking downward therapy was invigorating method to preserve mucus, and if mucus had been exausted with complicating emptiness prognosis had been appeared badly. 7. Preventing from Oui-Ga-Sil diet by rule, fitness to cold and warmth may be needed to prevent outside evil influence attack and inside evil influence occurrence. Prudence with being very busy, fatigue, wine and woman may be also needed not to be an injury to splanic and gastric spirit.
