The researcher worked with a total of 158 high school girls visiting the scaling practice room at the department of dental hygiene in Jinju Health college from November 11, 2002 to December 4, 2002, having their teeth scaled, observing their teeth and interviewing them with the aid of questionnaires. The findings can be summarized as follows. 1. The survey on the understanding of dental health and the attitudes of the subjects shows the following results : "I have never learned how to brush teeth" (65.8%: 104 girls); "I brush my teeth twice a day" (57.0%: 90 girls) : "I brush my teeth for 2 minutes"(44.3%: 70 girls): "I brush my teeth vertically and horizontally" (53.2%: 84 girls): "( brush my teeth, gum and tongue" (462%: 73 girls): "I use one brush for two months" (40.5%: 64 girls); "I don't have any floss" (582%: 92 girls): "I have never had my teeth scaled" (84.2%: 133girls) : "Smoking is bad for the teeth" (77.8%: 123 girls): "Drinking is bad for the teeth" (48.7%: 77 girls): "I have ever visited dental clinics" (92.4%: 146 girls). 2. The study on part of the teeth most exposed to caries shows the following results : Mandibular right first molar(79.8%: 126 girls): Mandibular left first molar(77.5%: 124 girls), Mandibular left second molar(70.2%: 111 girls). Mandibular right second molar(65.7%: 104 girls). Maxillary left first molar(59.5%: 94 girls): Maxillary left second molar(59.5%: 94 girls): Maxillary right first molar(58.2%: 92 girls). Maxillary right second molar(50.7%: 80 girls) 3. The statistics on the subjects' caries show the following results: DMF rate: 943%: DMFT rate: 25.61%: DMFT index: 7.17 teeth : DT rate: 4651%: FT rate: 52.25%: MT rate: 124% 4. The survey on dental caries statistics, dental health, dental health behavior, and the subjects' attitudes shows the following results: The worse the subjects' dental health was(r=-327, p<.001), the more they visited dental clinics(r=.195, p<.05), the higher DMT rate, DMFT index were; The more the subjects visited dental clinics(r =.359, p<.001), the higher DT rate was; The worse the subjects teeth went(r=-.197, p<.05), the higher MT rate was. It is necessary that systematic and substantial dental health education for high school students should be carried out in regard to plaque control, fluoride application, diet control, pit & fissure sealant as a part of developing national health policies designed for the dental health of the teenagers.

The purpose of this study was to examine the oral health care aware-ness of pregnant women and their actual oral health care in an effort to provide information on how to assist pregnant women to have the right knowledge on oral health and improve their oral health care. The subjects in this study were pregnant women who used obstetrics and gynecology hospitals or participated in pregnancy/child-rearing programs in the region of P. After a self-administered survey was conducted in July and August 2008, the following findings were given: 1. As for the best case of oral health care, the largest number(77.2%) of the pregnant women investigated brushed all the teeth, gums and tongue when they did toothbrushing. The smallest number of the women(6.8%) spent three minutes or more brushing their teeth. 2. As to dental treatment experience during pregnancy by age, 27.0 percent of the age 26-30 group had ever received dental treatment during pregnancy, which was higher than the rates of the other age groups with the same experience. 3. Regarding the necessity of oral health education geared toward pregnant women, 94.1 percent of the age 26-30 group and 96.3 percent of the group of age 31 and up felt the need for that, which were significantly higher than 72.7 percent of the age 20-25 group who agreed to the necessity of that education. 4. As to connections between oral health status and oral health care, the women who were in good oral health got 6.60 on oral health care. They scored significantly higher than those who were in a moderate state of oral health and who were in bad oral health, as the latter two groups respectively got 5. There was a significant correlation between oral health state and oral health care and between oral health knowledge and oral health care. The better oral health status led to better oral health knowledge, and the better oral health knowledge was followed by better oral health care. 6. As for factors affecting oral health care, oral health knowledge had the largest impact on that, followed by age, oral health status, experience of receiving oral health education for pregnant woman, dental treatment experience during pregnancy, monthly income and stress caused by oral diseases. Given the findings of the study, oral health education should be provided in light of the special physical and mental state of pregnant women. They should be encouraged to receive possible dental treatment during pregnancy if necessary, and they should learn about how to cope with a dental disease in case of develop it.

Objectives : In order to provide basic data necessary for developing oral health education plane for school continued oral health education by understanding knowledge and activities of oral health. Methods : This study was performed against 324 students at 5th grade of 2 elementary schools in Iksan-si, Jellabuk-do selected through convenience sampling, who were in mixed dentition period that might experience dental caries of permanent tooth. Results : As results, For the knowledge level on oral health by questions, it was found that the case that the elementary school students had correct knowledge on oral health was 'chocolates, snacks, and candies were foods that might often cause dental caries' and 95.8% of the students recognized it well. It was found that for 'must do toothbrushing before going to bed', 'during toothbrushing, I clean my tongue', and 'Proper time necessary for toothbrushing is about 3 minutes', 89.3%, 93.2%, and 89.3% of the students knew the, respectively. When oral health knowledge level by groups was divided into 3 groups and observed, they were classified into Low (0-4 points), Mid (5-7 points), and High (8-10 points). It was found that the knowledge level of each group was High 64.1%, Mid 33.9%, and Low 2.0% and it was identified that the high group took the largest ratio. It was suggested also for oral health knowledge level depending on their father's academic background that there was a statistically significant difference in the group higher than university graduate(p<.05). It was found for oral health knowledge level depending on parents' dental condition that an answer that both parents were good was high and there was a statistically significant difference. But post-analysis resulted that there was no apparent difference among groups. It was found that the ratio of respondents who answered for toothbrushing method 'toothbrush should be moved and rotated downward for the upper teeth and upward for the lower teeth to clean the teeth and gum' were 33.2% of male students and 29.4% of female students and showed statistically significant difference (p<0.05). It was found also that the ratio of respondents who answered to use a toothbrush for about 3 months' were 29.4% of male students and 25.5% of female students and showed statistically significant difference (p<0.05). Conclusions : Oral health program through the elementary school students and their parents for the development of proper oral health care education programs continue to be made should be considered.

The purpose of this study was to examine the satisfaction level of patients with oral health care provided by a dental hospital, especially scaling, and their oral health behavior. The subjects in this study were 263 college students who were in their 20s and selected from among patients who visited D university dental hospital in Gangwon Province during the oral prophylaxis practice of dental hygiene sophomores and juniors. The findings of the study were as follows: 1. Whether the selected students had ever had their teeth scaled was checked, and those who had outnumbered the others who hadn't. The rates of the former and latter respectively stood at 61.2 percent and 38.8 percent. Regarding places where they got their teeth scaled, the majority of the students that represented 75.2 percent did that at dental clinics. By gender, 34.4 percent of the male students did that at schools, which were larger than 11.8 percent of the female students who did. 88.2 percent of the female students did that at dental clinics, which were larger than 65.5 percent of the male students who did. Gender made significant differences to that(x2=10.79, p<.01). 2. As for satisfaction level with scaling by gender, the male students (38.7%) who had no specific idea outnumbered the female students (26.5%) who did. The female students(57.4%) who felt no pain during scaling outnumbered the male students(55.9%) who did. Gender made a significant difference to their responses. (x2=6.38, p<.05). 3. Concerning the use of oral hygiene supplies, most of the students who represented 72.2 percent had never flossed their teeth, and as many as 86.3 percent had never used a tongue cleaner. But the gaps between them and the others were not statistically significant.

This study considers the value of English-language films as material for learning a foreign tongue using posh discourse. In daily life, when we decline an invitation or convey unpleasant information to a listener, we use polite expressions; we are careful with our words. English language learners need to learn polite expressions in order to interact peacefully with others; doing so can minimize conflict, which is inherent in social relationships. This study uses the British drama Downton Abbey, which is about aristocracy. This study analyzes the posh discourse used in Downton Abbey and insists that students need to learn it explicitly. It is important to learn the polite expressions of this authentic drama in a real classroom. This study suggests that students work in groups to create a short video, and to try to understand the characters' personalities. Movies, TV dramas, and sitcoms provide great content that shows the various functions of the language that students want to learn. As a source of learning material, film can help improve students' motivation and interest in learning a foreign language.

In this paper, we studied the brain-computer interface (BCI). BCIs help severely disabled people to control external devices by analyzing their brain signals evoked from motor imageries. The findings in the field of neurophysiology revealed that the power of $\beta$(14-26 Hz) and $\mu$(8-12 Hz) rhythms decreases or increases in synchrony of the underlying neuronal populations in the sensorymotor cortex when people imagine the movement of their body parts. These are called Event-Related Desynchronization / Synchronization (ERD/ERS), respectively. We implemented a BCI-based mouse interface system which enabled subjects to control a computer mouse cursor into four different directions (e.g., up, down, left, and right) by analyzing brain signal patterns online. Tongue, foot, left-hand, and right-hand motor imageries were utilized to stimulate a human brain. We used a non-invasive EEG which records brain's spontaneous electrical activity over a short period of time by placing electrodes on the scalp. Because of the nature of the EEG signals, i.e., low amplitude and vulnerability to artifacts and noise, it is hard to analyze and classify brain signals measured by EEG directly. In order to overcome these obstacles, we applied statistical machine-learning techniques. We could achieve high performance in the classification of four motor imageries by employing Common Spatial Pattern (CSP) and Linear Discriminant Analysis (LDA) which transformed input EEG signals into a new coordinate system making the variances among different motor imagery signals maximized for easy classification. From the inspection of the topographies of the results, we could also confirm ERD/ERS appeared at different brain areas for different motor imageries showing the correspondence with the anatomical and neurophysiological knowledge.

Survey was initiated on insect pest species damaging the landscaping trees in golf courses to get the basic information for the development of insect management program. Four country clubs were selected as survey sites; Tongue Country Club and Youngwon Country Club in Gyeongnam, Daegu Country Club in Gyeongbuk, and Dongrae Benest Golf Club in Busan. We found that 60 species of 44 genera in 34 families of six orders from 88 species of 54 genera in 33 families of 22 orders surveyed. Most landscaping trees were damaged by one or two species of insect pests, but tree species such as Robinia pseudoacacia, Prunus leveilleana var. pendula, Castanea crenata, Quercus dentata, and Q. variabilis were damaged by more than five species of insects. Most insect species damaged one or two tree species. However, Adoretus tenuimaculatus(Coleoptera: Scarabaeidae) damaged 67 tree species of 41 genera. The Coleoptera and Honmoptera species were 36.4% and 36.3% of the total insect species, respectively. Insect pest occurring in high frequency was 9% of total insect species, while infrequent one was 73%. The insect species with chewing and sucking mouth part types were 49% and 51%, respectively.

As a continuation of a series of work on the physiology of the mamillary bodies, 3 experiments were carried out using 8 pointer dogs subjected surgical removal of this hypothalamic structure by subtemporal approach. In the first experiment, animals were tested per- and postoperatively in approach-avoidance situation. Food served as incentive, electric shock to the tongue as punishment, and response latency of postpunishment trial as an index of fear. The second experiment dealt with per- and postoperative tests in stress situation. A high frequency sound (12,000 cycle, 100 db sound for 1 hour) was regarded as a stressor, and decrease in blood eosinophil cell count as an index of response th the stress. Pre- and postoperative measurement of rectal temperature was carried out in the third experiment, using a clinical thermometer with decimal centigrade scale. The results obtained were as follows: 1. Tests in approach-avoidance situation showed no indication of increased or decreased fear response following removal of the mamillary bodies. 2. Postoperative stress response was as marked as that of preoperative period, but the recovery from the stress was significantly retarded after surgery. 3. The body temperature dropped slightly, but significantly following damage to the mamillary bodies.

This thesis is consisted of studying of the medical literature about Five sense of organs. Five sense of organs are the eyes, tongue, mouth, nose and ears. Five sense of organs are performed human senses which external sensory information by accepting an important feature for maintaining the biological activity to be performed. The contents was compiled up to the Donguibogam to Chinese literature and documents encompass the Korea medical literature, Donguibogam related to the senses to identify the citation of each chapter, the actual quotation through doctrine and other publications revealed that the citation is to investigate how accurately identified through studying the analysis and observation. It is as following as I observed carefully the senses of Donguibogam quotations related to each other through doctrine and publishment institution follows in order of dynasties. There are four volumes of Han-dynasty, one volume of Weijinnanbei-Era, two volumes of Tang-dynasty, nineteen volumes of SongJinYuan-dynasty, seven volumes of Ming-dynasty as Chinese medical literature. There are four volumes of Chosun-dynasty as Korean medical literature. It is the most quotation publishment that the books of SongJinYuan-dynasty of above thirty-six-volume. It is the latest quotation book that is Gujinyigan in Chinese medical literature and Euirimchwalyo in Korean medical literature. It is very positive quotation considering even Donguibogam publishment year in 1613. The reference books are four volumes of Chosun-dynasty as Korean medical literature and thirty-two-volume of Chinese medical literature. By observing the quotation frequency, 157 times in Sheyideaiofang, 115 times in Yixuerumen, 74 times in Yixuegangmu, 39 times in Wanbinghuichun, 31 times in Euibangryuchwi, 30 times in Renzhezhizhifang and Gujinyigan, 28 times in Danxixinfafuyu, 23 times Hwangdineijing, 17 times in Nanshibizang and Yixuezhengchuan. Other else books have been cited less than 10 times. It might be made error that did not find the source of the books even though cited reference, also even though defining the source of reference it is only rare reference book. As mention above, there are a lot of discovering as the feature of reference Publications. Most of all we could find out the reference literature cited in Donguibogam, however we couldn't clarify other books in original books. Thus, we should remember that it did not coincide with cited marks when studying the Donguibogam.

Occasionally, apoplexy is caused by functional or physiologic cardiopulmonary abnormality. In addition, theses may become the factor of aggravating apoplexy and involve complication. If patient has cardiopulmonary disease, progressing of apoplexy is commonly used to be accelerate and prognosis is deteriorative. There by the patient who has cardiopulmonary disease, should be particularly treated for cardiopulmonary disease. We got good result, during treat Soeumin cerebral vascular infarction patient who has pulmonary edema leaded from congestive heart failure, with Sasang Constitutional treatment. Therefore I reported them here. She was 68 years old, female patient. She visited our hospital for apoplexy with right side hemiparesis, dysphagia, dysphasia. After her admission into our hospital, we knew that she has congestive heart failure. The diagnosis is established. She presented with severe general edema and pulmonary edema. Although Soeumin edema usually classified as Taiyin Disease, we classified this as Shaoyin Disease, through diet, discharge, sleep, tongue and symptoms. We has prescribed Gungguichongsoyijung-tang(芎歸蔥蘇理中湯) in accordance with the principle of invigorating the Spleen and lower Yin(建碑而降陰). And her symptoms has improved.
