Vertigo is one of the common symptoms that we can see often clinically. It is hallucination to motion of oneself or surroundings. Vertigo include not only simple whirling sensation but also leaning or falling down sensation. Particularly in benign paroxysmal positional vertigo(BPPV), the principal symptom is dizziness and accompanied by nausea, lightheadness, vomiting. They are induced by positional change which like shake ones head or lay down or turn over in one' s sleep. Cause of BPPV is otoconium fragments which are released from inner ear and stimulate ampulla of semicircular canal. So in treatment BPPV, we often using the Dix-hallpike maneuver that realignment otoconium fragments. A case of vertigo patient suggested BPPV who is diagnosed oriental medically as weakly dizziness showed prominent improvement by medicate Bojungikgi-tang and operate otoconium-realignmentation (improved Dix-hallpike maneuver) maneuver so we reported.

Objective: The purpose of this paper is to report the improvement in a patient with benign paroxysmal positional vertigo (BPPV) treated with herbal medication based on the Shanghanlun disease pattern identification diagnostic system. Methods: According to the 'Disease Pattern Identification Diagnostic System based on Shanghanlun Provisions,'the patient was diagnosed with Guorem-byung number 350 provision, and took Baekho-tang herbal medication for 15 days. The result of administration was evaluated using the Dizziness Handicap Inventory (DHI) and the Visual Analog Scale (VAS). Results: After administration of Baekho-tang for 15 days, based on the 350 provision of Baekho-tang diagnosed according to the Shanghanlun provisions, the DHI score decreased from 74 to 16 and the VAS score decreased from 10 to 1. Conclusions: The patient recovered from symptoms of BPPV. This case report suggests that the words '滑,''厥,''裏'on the 350 provision of Shanghanlun mean physical and psychological causes of BPPV in this case.

Obstructive sleep apnea (OSA) is a disorder characterized by repetitive episode of upper airway collapse during sleep. Recent studies showed that not only the anatomic factors but the physiologic factors of the upper airway also have effcts on the occurrence of apnea and that the genioglossus muscle also plays an important role in the maintenance of the upper airway. A variety of therapies were performed to treat OSA, and among them the use of mandibular repositioning appliances showed reasonable results. But there is still a lack of research on the structural and physiological mechanism upon the use of mandibular repositioning appliances. The author selected 26(male 17, female 9) OSA patients that came to the Yonsei University Dental Hospital, Department of Orthodontics, and 20 normal adults (male 10, female 10) and took cephalometric radiographs of them in a supine position before and after the placement of the mandibular repositioning appliance to see the structural changes of the upper airway and compare the therapeutic effects between the two groups. We also studied the waking genioglossus muscle activity in OSA patients and investigated the difference in the electromyogram of the genioglosssus muscle upon the change in body posture and the use of mandibular repositioning appliance. Following results were obtained. 1. Among the cephalometric measurements of the upper airway structure, the length of the soft palate, maximum thickness of the soft Palate and SPAS, MAS, VAL, H-H1, MP-H showed statistically significant differences between the normal and OSA groups, but the IAS and EAS showed no statistically significant differences between the two groups. 2. In both the normal and OSA groups, as the epiglottis moved forward on wearing the mandibular repositioning appliance, the epiglottis level of the upper airway increased and the maximum thickness of the soft palate changed and the hyoid bone also moved forward, but the IAS in both groups showed various results and the effect of the mandibular repositioning appliance on the structure of the upper airway was different in the two groups. 3. Upon changing the position, the electromyogram of the genioglossus muscle showed a increasing tendency but there was no statistically significant differences, and when the mandibular repositioning appliance were worn there was a statistically significant increase in the electromyogram of the genioglossus muscle in both the upright and supine positions. The mandibular repositioning appliances not only have an effect on the anatomical structure of the upper airway but also on the physiology of the upper airway. There are different responses to the use of mandibular repositioning appliance between the normal and OSA groups therefore it could be considered to have the different physiology of the upper airway between the two groups.

Comparing the amount of Hb, the nutriture of the deaf-mutes are better than that of the amentias and the nursery school children. The former, however, shows less condition than that of the boys and girls in the junior physical education school (Hb : 12.7) and the normal family children (Hb : 10.8). In the group of six to eleven years old that is a class a elementary school, the physical condition such as stature, chest circumference, and weight of the deaf -mute is respectively almost the same degree, which is above standard in our country. On the contrary the degree of the amentias and the nursery school children has an inferiority approaching to the standard. In the group of twelve to fifteen years old that is a class of junior high school, the nursery school children have the lowest physical condition and the boys and girls of the physical training school the highest. The order of the growth of physical condition is as follows : Nursery school children

This nutrition survey was carried out twice(Spring and autumn) in Sam Chung-Ri, Song Kwang Myun, Soong Ju-Gun. The food intakes of 92 family members were measured by weighing method. Also 45 adults were examined for anthropometric, blood content and blood pressure. The results abtained were summarized as follows; In vegetable foods, the intake of rice was high, but that of legumina and other cereals was low. In animal foods, the intake of milk and eggs was low, and that of oils and fats was very low. However, the food intake between spring and autumn showed remarkable difference. The average intake of calorie, protein, Ca, Fe and vitamin $B_2$ except vitamin $B_1$ and niacin was below the RDAs. The percentage of carbohydrate, protein and fat for energy was 82.2, 11.6 and 6.2%, respectively. The results of anthropometry of height, weight and chestcircumference showed that both sexes Were below Korean Standards. The concentration of Hb & Hct was normal in both sexes, and the rate of anemia was low. The concentrations of plasma glucose, protein, lipids, and blood pressure were normal in both sexes. In case of male, the correlation between plasma albumin and nutrients intake was significant, but the case of female showed different tendency. In case of male, the correlation between weight, height and plasma protein was also significant but the case of female showed different tendency. The rate of parasite infection was very low $(2.17%{\ldots}3.26%)$

A pedestrian accident is generally less fully understood than the 'typical' car-to-car collision. For this reason, the analysis of the pedestrian accident is, in many respects, more complicated and demanding. The purpose of this study is to identify clearly the impact point that is the main subject of struggle in pedestrian accidents. In order to develop the model, it is very significant to classify actual accident data including impact velocity. vehicle damage and injury scale of pedestrian. These data were collected from three local branches of RTSA(Road Traffic Safely Authority). The number of collected data were 34 cases and 61.7% of them were fatal accidents. In consequence of analyzing the data by statistical method, it revealed that there is correlation between impact velocity and throw distance. It, also shows that the impact velocity has strong linear correlation to vehicle damage and injury scale. Consequently, reconstruction analysis models of pedestrian accidents considering in local circumstances(such as the physical characteristics of pedestrians and vehicles) was developed However. it is difficult to apply the result of this study to all sorts of pedestrian accidents, because the actual accident data which were used to develop the model were limited. To overcome this limitation, it is necessary to develop an analysis model applicable to diverse circumstances with a wide range of pedestrian accident data on a national basis.

The eight hundred fourteen male and female elderly living in urban and rural area of Incheon were compared in terms of anthropometric indices and health related factors. Mean height, weight, BMI, WHR, MAC, TSF, %body fat and systolic blood pressure of male elderly were 162.7cm and 162.0cm, 61.8kg and 58.3kg, 23.2 and 22.0, 0.91 and 0.89, 24.4cm and 24.0cm, 9.9mm and 11.5mm, 23.9% and 23.2%, 152.1mmHg and 150.0mmHg in the urban and rural respectively. In female elderly, mean height, weight, BMI, WHR, MAC, TSF, %body fat and systolic blood pressure were 150.3cm and 149.2cm, 55.9kg and 53.1kg, 24.4 and 23.4, 0.87 and 0.86, 25.4cm and 24.4cm, 20.2mm and 18.9mm, 37.2% & 35.4%, 142.2mmHg and 151.7 mmHg in the urban and rural respectively. As the age increasing, most of the anthropometric indices are decreased while systolic blood pressure are increased in both gender. The proportion of the subject with normal hearing were 73.1% in the urban, 61.4% in the rural and 61.8% in the male, 73.1% in the female. Hearing and tooth status became deteriorated as increasing the age and the more elderly felt themselves unhealthy as increasing the age. Aerobic(25.7%) and walking/jogging(18.4%) in the urban, walking/jogging (22.1%) and climbing(3.5％) in the rural were the preferred exercise in the elderly. Frequency of health promoting substance intake were very low and not significantly different between the urban & the rural, and the male and the female elderly. Neuralgia, diabetes, indigestion and cerebral stroke showed relatively higher morbidity in the elderly. Neuralgia was significantly higher in the female(23.3%) than in the male(13.1%). Diabetes was significantly higher in the female(22.4%) and the urban(21.9%) elderly than in the male(16.1%) and the rural(13.5%) elderly respectively. In conclusion, as the age increasing the height and weight of the elderly decreased significantly and BMI, WHR and body fat toned to decrease. Hearing and tooth status deteriorated significantly as the age increasing, especially in female elderly.

For the purpose of the better dietary management and to emphasize of importance in nutrition education for 949 woman workers at the dormitory of wig factory in Seoul, the nutritional survey was conducted for seven days from August 13 th to 20 th of 1969. The survey included food and nutrient intakes, physical measurement, clinical findings and biochemical measurement were conducted for the randomly sampled 44 subjects. According to the survey results, their heights was under the standard and the 82% of the total subjects was the age ranges from 16 years to 20 years old. Their daily menu was not planned properly and the concept of 5 basic food groups was not utilized in their menu planning. The balanced meal should be emphasized in this factory. Calories and protein intakes are low compared with the recommended allowance and especially animal protein intake is low. Fat intake is only 8.8 grams for capita per day. Vitamins and minerals intake are also low. Clinical and biochemical survey indicated various vitamin deficiencies and anemia which is mostly due to the iron insufficiency.
