Fowl typhoid is a septicemic disease of turkeys and chickens. The antigen is Salmonella(S) gallinarum, which cross-reacts with S pullorum because of common antigen. The organism is maintained in the ovary of carrier birds and transmitted vertically in the york. It is also transmitted horizontally through feces and broken eggs. The symptoms are weakness, drowsiness, wing drooping, hyperexcitability, paresis and diarrhea. In the many cases, the birds are found dead in the morning before any symptoms have been noticed. this experiment was carried out to investigate the characteristics of S gallanarum and scrutinized about the control systems. 1. Fowl typhoid was came about in the winter than the other seasons. The average of mortality was 46.3%. And it was came about not only adult poultry but also chicks. 2. S gallinarum was isolated from liver and spleen in infected chickens. Total isolated strains were 60. 3. The organisms were all extinct at 60$^{\circ}C$, 30mins. 4. A survival rate was higher in underground water than a secondary distilled water. It was detected in underground water until 30 days. 5. When being exposed to the solar light, it became extinct almost within 24 hours. 6. It was survived in a refrigerator until 12 months. 7. It was extinct among 5 mins in 0.1% phenol and 2% formalin. 8. When the cultured organism fluid was inoculated in SD-rat abdominal cavity, rat died within 24 hours. 9. Pullorum-typhoid related program must disciplines in order to destroy the fowl typhoid, and breeding system must be converted to cage system.

We present one case of 26-year-old male having saddle block combined with mitral valvular disease [NYHA Class IV] with auricular fibrillation. The most common cause of emboli is atrial fibrillation. The clinical manifestations of saddle emboli are relatively slow due to development of collateral circulation and large size of lumen of the aorta. The 5month duration of saddle emboli in this case led to severe atrophic changes, coldness, peripheral cyanosis on the both lower extremities, and flexion deformity on the knee and ankle joint of the left lower extremity. We planned staged operation for the saddle block and for mitral stenoinsufficiency and tricuspid insufficiency, because of poor general condition of the patient. The thromboembolectomy of aortic bifurcation was performed through the transabdominal approach without trial of Fogarthy catheter embolectomy, because of expectation of the secondary inflammatory changes of the vessel wall and thrombi which was 3 cm X 1 cm X 0.5 cm in size with irregular surfaced solid in consistency. 1 month later, after thromboembolectomy, mitral valve replacement and tricuspid annuloplasty were performed, with successful early operative result. During operation organized thrombi [1 cm X 0.5 cm] in the left auricle was removed. We wonder if simple management using Fogarthy catheter might be possible to remove the thromboemboli instead of thromboembolectomy by aortotomy in this case.

Residual significant tricuspid regurgitation after mitral valve operation may significantly increase postoperative morbidity and mortality. However, routine techniques to detect tricuspid regurgitation preoperatively and postoperatively are not accurate. Doppler echocardiography was performed preoperatively and postoperatively to assess its ability to evaluate and quantify the severity of tricuspid regurgitation. In 34 patients with tricuspid regurgitation secondary to mitral valvular disease the tricuspid regurgitations were semiquantified on a scale of 1 to 3+. The 34 patients were divided into two groups on the basis of severity of tricuspid regurgitation as assessed by preoperative Doppler echocardiography. Group I [8 patients] had mild[1+] regurgitation, and group II [26 patients] had moderate to severe[2 ~ 3%] tricuspid regurgitation. In all studied patients, preoperative Doppler echocardiographic studies for the degree of tricuspid regurgitation were correlated with clinical symptoms[including NYHA class] and hemodynamics[JVP and right ventricular systolic pressure], and used as the indicator to determine whether tricuspid annuloplasty should be performed or not. Patients with significant tricuspid regurgitation[group II ] had greater preoperative right ventricular systolic pressures and NYHA classes, although there was no correlation between them. The 8 patients with mild[1+] tricuspid regurgitation[group I ] didn`t undergo any procedure for the tricuspid regurgitation and their postoperative Doppler echocardiographic studies showed the less than mild[0 ~ 1+] tricuspid regurgitation, and the 26 patients with significant[>2+] tricuspid regurgitation, and the 26 patients with significant[>2+] tricuspid regurgitation[group II ] underwent tricuspid annuloplasty for the tricuspid regurgitation and the postoperative Doppler echocardiographic studies showed the findings similar to group I except 1 patient who underwent Carpentier`s ring annuloplasty and had severe right ventricular failure. Therefore, preoperative Doppler echocardiography can accurately assess the relative severity of tricuspid regurgitation. Importantly, postoperative Doppler echocardiography could conveniently determine the effect of tricuspid annuloplasty for the patients with significant tricuspid regurgitation. Doppler echocardiography may be an important diagnostic method both for evaluating the degree of residual tricuspid regurgitation after left heart operation as well as for determining which patients should undergo tricuspid valve repair.

Purpose: The purposes of this study were to check the obesity of middle and high school students in the nation and identify factors influencing their obesity. Methods: The present study is a secondary analysis research that obtained permission to use the primitive data of 10th (2014) Online Survey on Adolescents' Health Behaviors by the Korea Centers for Disease Control and Prevention and analyzed the primitive data according to the purposes. Results: The findings show that the BMI of middle and high school students in the nation was $20.7kg/m^2$ with the obesity and non-obesity group recording $27.0kg/m^2$ and $19.9kg/m^2$, respectively. Factors influencing the obesity of adolescents include gender, grade, educational background of parent, school grades for the last 12 months, satisfaction with sleep, fast food consumption, ramen consumption, intense and muscle exercise three times a week or more, subjective sense of health, stress, suicidal ideation, and hours of Internet usage per week. Conclusion: For the management of adolescent obesity, there is a need for obesity management programs taking the characteristics of male students into consideration. The possibilities of obesity grow according to the grades, which means that both the teachers and parents should offer more guidance on weight control in upper grades. The adjustment of adolescent obesity requires psychological health management including stress and suicidal ideation as well as diet control and exercise. It is also needed to apply a stepwise obesity management program according to the hours of internet usage and dependence on the internet

Background: In recent years, the interest in health and safety in the workplace has increased. Agriculture is one of the human work activities with the highest risk indexes. Studies on risk perception of agricultural workers are often referred to as specific risk factors (especially pesticides), but the risk perception plays an important role in preventing every kind of accident and occupational disease. Methods: The aim of this research is to test a new method for understanding the relation between risk perception among farmers and the main risk factors to which they are exposed. A secondary aim is to investigate the influence of training in risk perception in agriculture. The data collection was realized using a questionnaire designed to investigate the risk perception; the questionnaire was given to a sample of 119 agricultural workers in central Italy. Through the use of the "principal components analysis" it was possible to highlight and verify the latent dimensions underlying the collected data in comparison with scales of attitudes. Results: Results show that the highest percentage of strong negative attitude is among the people who have worked for more years, while farmers who have worked for fewer years have a marked positive attitude. Conclusion: The analysis of the questionnaires through the synthetic index method (Rizzi index) showed that agricultural workers involved, in particular the elderly workers, have a negative attitude towards safety; workers are hostile to safety measures if they have not attended special training courses.

This study was done in order to investigate the treatment of occidental and oriental medicine on dementia(mainly senile dementia and cerobrovascular dementia). The results were as follows ; 1. Dementia must treat a direct causes, but uncountable dementia(senile dementia) and cerobrovascular dementia can't treat at present. 2. Sciopsychological treatment in very important in dementia patient ; maintance of appropriate stimulation, psychological rest, physical examination, dietary cure and safety device is needed. On secondary mental disorder, antipsychotics, anxiolytics and antidepressants have to prescribe properly. 3. Treatments of Senile dementia(uncountable cerebral degenerative disease) proscribed hydergine which is peripheral vasodilator and physostigmine which increase cholinergic activity of brain, but this have slight effect on some patients. On treatments of cerobrovascular dementia, the medication that improved the cell metabolism and circulation of brain, this improved only a subjective symptom, but isn't foundamental treatment. 4. A tonic medicine is used basically, the methods are as follows. 1) Kenwihwadam(健胃火痰)-Sesimtang(洗心湯) 2) Bosiniksu(補腎益髓)-Hwansodan(還少丹) 3) Bosimiksin(補心益腎)-Gyuibitang(歸脾湯), Singyuo(神交湯) 4) Boheoansin(補虛安神)-Cilbokem(七福飮), sanggitang(生氣湯) 5) geoeohwalhyel(祛瘀活血)-tonggyuhwalhyeltang(通竅活血湯), 5. Acupuncture therapy on dementia used follow acupuncture point ; Yamen(啞門 GVl5), Laokung(勞宮 HC8), Tsusanli(足三里 ST36), Shenshu(腎兪 BL23), Tachui(大椎 GVl4), Chiuwei(鳩尾 CVl5), Sanyinchiao(三陰交 SP6), Yungchuan(涌泉 KI1), Shipsun(十宣), Shousanli(手三里 LI10), Taichong(太衝 LV3) In moxibustion therapy, Dachui(大椎 GVl4) point is used.

Our Team Approach consists of following five stages; (1) Peri-natal care until lip repair After ultrasound diagnosis, some obstetricians recommend the mother with CL/P fetus to undergo prenatal counseling in our CLP clinic. On the day the CL/P baby was born, our oral surgeon, nurse, and pedodontist visit the maternity clinic, and take counseling and take impression for a feeding plate. The cheiloplasty is performed in three months old. (2) From lip repair to palatal repair At one year of age, Otorhinolaryngologist checks middle-ear disease. Palatoplasty is carried out at 1.5 - 2 years old. (3) In deciduous and early mixed dentitions Speech is the most important issue in social life for the CL/P subjects, therefore the training of velopharyngeal function is essential. Orthodontist monitors dentofacial development from 5 years of age. In the case of severe maxillary under-growth or severe collapse, maxillary protractor or lateral expansion is indicative, respectively. In early mixed dentition, upper central incisor on the cleft area erupts with some torsion, and then the traumatic occlusion with tooth torsion must be corrected. (4) In mixed dentition Right before the eruption of upper canines, secondary bone grafting is performed. One year prior to the operation, maxillary fan-type expansion is carried out to correct the collapse of maxillary segments. Following the surgical operation, the erupted canine will be moved into the transplanted bone to avoid alveolar resorption. (5) In permanent dentition Final tooth alignment is carried out after eruption of second molars. Some cases may require orthognathic surgery after physical maturation. Prosthetic oral rehabilitation including the dental-implant is carried out after age eighteen.

Despite of a long history of the sulfur on the disease healing effect, there were limited ways of applying sulfur to animal and human. We have developed the detoxified sulfur (non toxic sulfur) method to make it practical and mass production possible through laboring for many years. This study practiced scanning electron microscope (SEM), Energy dispersive X-ray spectrometer (EDS) and secondary ion mass spectrometry (SIMS) analysis to investigate the physicochemical aspect of detoxified sulfur. We also performed the oral toxicity experiment to mice, and anti-bacterial test of the detoxified sulfur. Based on the SEM, EDS and SIMS results, the united particles in the mass form with the similar component intensity with the raw sulfur were observed, and hydrogen sulfide ion (HS-) component which is regarded as a toxic matter, was decreased after detoxification. Indeed, toxicity test on the mice (10 males, 10 females) showed no clinical, histopathological changes with the 5 times amount (2,500 mg/kg) of the actual doses. However, the male-mice showed decreased in body weight by 23.6%, 24.3% in the 7th, 14th day, respectively, after detoxified sulfur. Moreover, the female-mice administered the detoxified sulfur showed decreased in body weight by 28.7% (P<0.05) than that in the control group on the 14th day. The result of antibacterial test on the detoxified sulfur showed antibacterial effect (27%) to inhibit the growth of Staphylococcus aureus. It is shown that detoxified sulfur can be used as feed additive and has an affect on the farm perfomance.
