In the Encyclopedia Medica Koreana(Dongeuibogam), I have researched 245 prescriptions in which Panax Ginseng plays an important role. And I have got the following results. The healing scope and frequency of ginseng-mainly-included prescriptions are Child Part 29(11.83%), Violent Cough Part 23(9.38%), Sick-by-Cold Part 21(8.57%), Oncosis Part 16(6.53%), Overwork Part 14(5.71%), Gynecologic Part 14(5.71%), Internal Part 13(5.3%), Apoplexy Part 11(4.48%), Mind Part 10(4.08%) and Fecal Part 10(4.08%) prescriptions. And also each of Nausea Part, Anger Part, and Spirit parts has the same 5 (2.04%) prescriptions. And each of Qi Part, Diabetes Meatus Part, Malaria Part, and Humoral Part has 4(1.63%) prescriptions. And each of Foot Part, Choleraic Part, Genital Part, Blood Part, and Voice Part has 3 (1.2%). All of these prescriptions cover 88.88%. And besides listed parts above, Panax Ginseng is all used in 48 Parts: Body-Mind Part. Mouth-Tongue Part, Breast Part, Muscle Part, Swelling Part, Urine Part, Epidermis Part, Heat Part, Anus Part, Stomach Part, Eye Part, Laryngopharynx Part. Uterus Part" Heavy Stomach Part, Head Part, Pulse Part, Hair Part, Navel Part, Emetic Part, Costal Part, Edema Part, Vomiting Part, Superstitious Part, and Cardiac Part, etc. Of the prescriptions in which Panax Ginseng plays an important role, the most representative diseases, which more than 86.8% prescriptions cure, are shock, numbness from cold, Taeeum disease, oncosis, overwork, sick from eating, numbness of extremities, diarrhea, tachycardia, forgetfulness, nausea, heat from kidney, nocturnal emission, short breath, diabetes meatus, malaria, sweating, sweating overnight, beriberi, cholera, insomnia from enervation, sialitis, navel pain, hemorrhage, and loss of voice. The pathology of the prescriptions in which Panax Ginseng plays an important role is divided into the organ problems, six natural factors, seven extreme feelings, unbalanced humoral status, overwork, and, unbalance of qi and blood. Spleen, heart, and uterus is the main cause of organ problems; wind and cold are the main cause of six natural factors; heavy humors are the main cause of unbalanced humoral status; the stasis of seven feelings are the main cause of seven extreme feelings; the lack of stamina and overwork are the main cause of the overwork; the lack of qi, the lack of blood, and, the lack of qi and blood are the main cause of the unbalance of qi and blood. After I have researched the contents of the prescriptions in which Panax Ginseng plays an important role, I could understand the addition of the different prescriptions, combination of medicines, and the role of medicine groups associated with Panax Ginseng. So from now on, the results I have got could be used as the data which show the theoretical basis on the prescriptions.

Intermaxillary fixation and occusal splint are routine procedure for maxillofacial fracture and orthognathic surgery. When these methods could obstruct oral airway the patients who kept intermaxillary fixation and occusal splint in their mouth, are very difficult to breath after surgery. Nasal bleeding and pharyngeal edema due to nasotracheal intubation, residual effect of muscle relaxants, and anesthetic agent could be contributing factor of airway obstruction. In this study, pulmonary function test was evaluated before and after intermaxillary fixation, and intermaxillary fixation with occusal splint in 22 volunteers. The results were as follows 1. FVC, %FVC, $FEV_1$, $FEV_1%$, PEF, $PEF_{50}$, MVV without intermaxillary fixtion were 4.45L, 88%, 4.03L, 90.9%, 10.26L/s, 5.53L/s, and 136.14L/min, and with intermaxillary fixation were 3.51L, 68.67%, 3.06L, 69.39L, 6.52L/s, 3.94L/s, and 69.39L/min. The results with intermaxillary fixation and occusal splint were 2.15L, 42.41%, 1.71L, 38.81%, 2.83L/s, 1.74L/s, and 37.14L/min. 2. Compared with before and after intermaxillary fixation, all values of pulmonary function test were decreased and after intermaxillary fixation and intermaixillary fixation with occulasal splint, the results were decreased. 3. MVV and PEF were decreased significantly with interaxillary fixtion and occusal splint, and FVC was less decreased. It meant that intermaxillary fixation and occluasal splint induced reduction of respiratory flow significantly, but less reduction of respiratory volume. 4. Intermaxillary fixation and occulsal splint induced increase of airway resistance, decrease of expiratory volume and air flow. So severe respiratory difficulty could be seen to all volunteers who kept intermaxillary fixtion and occusal splint. 5. In classification of respiratory difficulty, intermaxillary fixation with occulsal splint induced complex respiratory difficulty more than intermaxillary fixation only did. From the above results, doctors who care patients kept intermaxillary fixation and occusal splint should be aware of respiratory depression caused by these treatment.

Three dogs with suspected patent ductus arteriosus were referred to Veterinary Medical Teaching Hospital of College of Veterinary Medicine, Konkuk University because of cough, shortness of breath, exercise intolerance, and syncope, Continuous murmur and thrill were detected in physical examination. Left ventricular enlargement, cardiomegaly, bulged main pulmonary artey were found in radiography. Tall R wave, wide P wave, atrial fibrillation, and turbulent flow were observed in electrocardiogram and echocardiogram. Thoracotomy was performed at left fourth intercostal space under isoflurane anesthesia. Patent ductus arteriosus was double ligated with 1-0 silk. The median (mean ${\pm}$ SD) diameter of patents was $8.0{\pm}2.0mm$. The median operation time was $36{\pm}6.6min$. On examination right after surgery, continuous murmur, thrill, atrial fibrillation, and turbulent flow were disappeared. On 30 days after surgery, clinical signs, left ventricular enlargement, and, bulged main pulmonary artery were disappeared. VHS 12.5 and 13.5, R wave 3.3 and 3.0 mV, and P wave 0.05 and 0.05 sec were decreased to 10.0 and 10.5, 1.8 and 2.0 mV, and 0.04 and 0.04 sec respectively in case 1 and 2. Ratio of aorta and main pulmonary artery in diameter was changed 1 : 1.3 and 1 : 1.6 into 1 : 1.1 and 1 : 1 respectively in case 1 and 2. Mild tear developed during dissection in case 3 and hemorrhage was controlled by vascular Devakey forceps. However, the dog died. On 12 months after surgery, patients (case 1 and case 2) have not showed abnormal signs.

이비인후과 영역에서의 결석증은 타영역에 비해서 비교적 드물게 발견된다. 편도 결석은 만성편도염 환자의 소여포를 채우고 있는 건락성 충진물의 중심부에서 발견된다. 어릴때 편도염을 자주 앓았던 성인에서 발견되는 것이 보통이고, 증상으로는 구개내 이물감 및 악취를 환자 자신이 느낀다. Keratohyalin이 축적되어 결석을 형성하고 있으며 염증이 동반되면 인두통, 인통, 연하통 연하곤란등이 있을 수 있다. 비석은 비강내 이물, 응혈, 세균 가피 농후한 분비물 등이 핵이 되어 그 주위에 칼슘, 마그네슘등이 침착해서 형성된다. 성인에 따라서 외인성과 내인성으로 구분되는데, 외인성의 경우는 비강내 이물에 의해서, 내인성의 경우는 기왕에 존재하던 비질환에 의해서 각각 비폐쇄가 유발되며, 비루에 지장이 초래되어 분비물의 울혈을 가져와서 비석을 형성하는데 기여한다. 성인, 여자에서 잘 생길 수 있으며 대개 편측성이고 비강저부에저 발견되는 것이 보통이다. 대개 완만한 성장을 보이므로 상당기간은 아무런 증상없이 지내다가 비폐쇄, 비출혈, 악취나는 점액농성 분비물을 주소로 내원하는 수가 많다. 저자들은 이비인후과 영역에서도 희귀하게 발견되는 편도결석 1례와 거대한 비석 1례를 최근에 치험하였기에 문헌고찰과 함께 보고하는 바이다.

The electronic nose (e-nose) has been used in food industry and quality controls in plastic packaging. Recently it finds its applications in medical diagnosis, specifically on detection of diabetes, pulmonary or gastrointestinal problem, or infections by examining odors in the breath or tissues with its odor characterizing ability. Moreover, the use of portable e-nose enables the on-site measurements and analysis of vapors without extra gas-sampling units. This is expected to widen the application of the e-nose in various fields including point-of-care-test or e-health. In this study, a PDA-based portable e-nose was developed using micro-machined gas sensor array and miniaturized electronic interfaces. The rich capacities of the PDA in its computing power and various interfaces are expected to provide the rapid and application specific development of the diagnostic devices, and easy connection to other facilities through information technology (IT) infra. For performance verification of the developed portable e-nose system, Six different vapors were measured using the system. Seven different carbon-black polymer composites were used for the sensor array. The results showed the reproducibility of the measured data and the distinguishable patterns between the vapor species. Additionally, the application of two typical pattern recognition algorithms verified the possibility of the automatic vapor recognition from the portable measurements. These validated the portable e-nose based on PDA developed in this study.

The purpose of this study was to examine the state of smoking among some college students, the smoking motivation of smoker students, what made them quit smoking and how they got ready for giving up smoking, as smoking had a huge impact on national health and there was a desperate necessity for preventive antismoking education programs to let students keep away from smoking. After a survey was conducted with self-administered questionnaires from October 1 through November 1, 2006, the responses from 400 students were gathered, and 384 answer sheets were analyzed except 16 incomplete ones. The findings of the study were as follows: 1. By gender, 62.4% of the male students and 28.6% of the female students were smokers, and the state of smoking was statistically significantly different according to their gender(p<0.05). 2. The largest number of the male students, which accounted 44.1%, started smoking in their high school days, and 39.5% of the females did that in middle school. As for a daily mean amount of smoking, 41.8% of the male students, the greatest percentage, smoked 10 to 19 cigarettes a day, and one to nine cigarettes were most common among the females, which represented 57.9 %. But the gap between the two was insignificant(p>0.05). As many as 83.6% of the males and 86.8% of the females had ever attempted to quit it. 3. Concerning awareness of antismoking policies, they felt that a raise in cigarette price would lead to less smoking, and that antismoking advertisement or posters through television or newspaper would deliver the same results as well. There was a statistically significant difference among their awareness(p<0.05). 4. Regarding preparation stage for quitting smoking, 31.3% of the male smokers had no intention to give it up, and 23.2% considered it. 36.7%, the largest percentage, got ready to refrain from it. Among the female smokers, 34.2% had no plans to abstain from smoking, and 36.8% took it into consideration. 23.7% got ready to do that. The females who got ready for that were outnumbered the males who did. 5. As to connections between the state of smoking and relevant knowledge, the students didn't have a good knowledge on that, and a statistically significant difference existed between the smokers and nonsmokers in smoking knowledge. 6. As for knowledge about oral diseases, they were highly cognizant of the relationship of smoking to tooth discoloration, nicotine stomatitis and bad breath, but they didn't know well about its relationship to delayed recovery from dental treatment, implant failure and ozena. Their smoking condition made a statistically significant difference to their knowledge(p<0.05). In the future, sustained research efforts should be channeled into determining how much smoking affects health and concerns oral diseases, and antismoking counseling programs should be prepared to bolster people's awareness of oral health.

Background: Understanding the burden of disease is important to establish cost-effective treatment strategies and to allocate healthcare resources appropriately. However, little reliable information is available regarding the overall economic burden imposed by chronic obstructive pulmonary disease (COPD) in Korea. Methods: This study is a multicenter observational research on the COPD burden in Korea. Total COPD costs were comprised of three categories: direct medical, direct non-medical, and indirect costs. For direct medical costs, institutional investigation was performed at 13 medical facilities mainly based on the claims data. For direct non-medical and indirect costs, site-based surveys were administered to the COPD patients during routine visits. Total costs were estimated using the COPD population defined in the recent report. Results: The estimated total costs were approximately 1,245 million US dollar (1,408 billion Korean won). Direct medical costs comprised approximately 20% of the total estimated costs. Of these, formal medical costs held more than 80%. As direct non-medical costs, nursing costs made up the largest percentage (39%) of the total estimated costs. Costs for COPD-related loss of productivity formed four fifths of indirect costs, and accounted for up to 33% of the total costs. Conclusion: This study shows for the first time the direct and indirect costs of COPD in Korea. The total costs were enormous, and the costs of nursing and lost productivity comprised approximately 70% of total costs. The results provide insight for an effective allocation of healthcare resources and to inform establishment of strategies to reduce national burden of COPD.
