In South Korea, traffic accident patients can be treated under automobile insurance coverage. This study investigated the status of Korean medicine (KM) Automobile insurance system and usage status of main pharmacopuncture in KM clinic which reported that the largest number of automobile insurance fee claims among medical institutions. We surveyed 258 traffic accident patients who were treated at Namsangcheon KM clinic from 2014 to 2018 according to medical chart. The majority of the patients were male and thirties. In traffic accident situation, the highest distribution was car to car crash with 85.66% and 66.67% of the patients visited in the most acute phase. The most frequent treatment period was within 4 weeks and the number of treatments was 10 or less with 72.87%. In total results of treatment, the distribution was exellent with 10.08%, good with 46.90%, fair with 27.13% and poor with 15.89%, and the effective rate was 84.11%. The most frequent treatment period was within 4 weeks with 64.73% and the number of treatments was 10 or less with 72.87%. Of the 242 patients who received pharmacopunture, 91.5% were treated with HO, which was named after Honghwaja and TA, which was named after traffic accidents, and there were significant differences in the number of treatments and symptom improvement between the two groups. In this study, we confirmed the status of automobile insurance treatment and usage of main pharmacopuncture of single KM clinic with symptom improvement. This study can be regarded as one of the basis of KM treatment for the rapidly growing automobile insurance market.

This research studied the relevance of oral symptoms and fear to find solutions for prevention and treatment at the right time. The study was conducted over a three-month period from September to November 2015. College students who lived in the region of Busan were surveyed, and the data from 288 respondents were analyzed. The female students felt a higher level of fear in every item than the males. To be specific, there were statistically significant differences in postponing the appointment (p=0.014), tension during treatment (p=0.001), dread when making the appointment (p=0.001), dread upon arrival (p=0.001), dread in the waiting room (p=0.001), dread of dental smells (p=0.006), dread while undergoing anesthesia (p<0.001), dread when receiving an injection (p<0.001), dread when looking at a tool for tooth preparation (p<0.001), dread of the sound of a tool for tooth preparation (p<0.001), dread of the feelings of tooth preparation (p<0.001), dread during scaling(p<0.001), and apprehension about the entire treatment (p<0.001). Concerning the fear level according to oral symptom awareness, the respondents with dental caries experienced a higher level of fear in terms of treatment avoidance (p=0.001), physiological reactions (p=0.001) and overall Dental Fear Survey (DFS)(p=0.003), and the students whose teeth were broken had a higher level of fear in terms of treatment avoidance (p=0.010), stimulus factors (p=0.031) and overall DFS (P=0.019). The students who had a missing tooth felt a higher level of fear in terms of physiological reactions (p=0.019) and overall DFS (p=0.033), and the respondents with gingival pain felt a higher level of pain in terms of the stimulus factors (p=0.013) and overall DFS (p=0.034). Therefore, college students should be educated to visit a dental clinic when they are aware of any oral symptom, and methods to reduce the stimulus factors as much as possible should be considered carefully to relieve dental fear.

During a learning process, a human being is assumed to experience knowledge-based behaviors, rule-based behaviors, and skill-based behaviors sequentially if Rasmussen was right. If any psycho-physiological symptom to those different levels can be obtained, it can be useful as a measure whether a human being is fully trained and has gotten a skill in his work. Therefore, this study aimed to draw relationships between human performance measures and psycho-physiological measures while committing a computer-simulated pointing task by utilizing the power spectrum technique of EEG data, especially with the ratio of relative beta-to-alpha band power. The result showed that, during correct responses, the ratio came to stabilize as all the performance data went stable. However, response time was not a simple linear function of task difficulty level only, but a joint function of task characteristics as well as behavior levels. Comparing relative band power ratios from errors and correct responses, activated states of one's brain could be explained, and characteristics of the task could understood. To tell that of pointing task, correlations around C3, C4, P3, P4 and 01, 02 area were significant and high in correct response cases whereas most correlation coefficients went down in error cases standing for imbalance of psycho-motor functions. Though task difficulty was the only one factor that could influence on relative band power ratio with statistical significance, it should be comprehended to mean a different way of expression indicating task characteristics since at least error-some situation could be explained with the help of relative band power ratio that absolute band power failed.

Background: Abnormal uterine bleeding (AUB) is the most important symptom of endometrial hyperplasia and endometrial curettage (EC) is the gold standard diagnostic procedure. We present the results of patients who underwent EC for AUB and the efficacy of progestin administration in those with endometrial hyperplasia. Materials and Methods: A total of 415 female patients who presented to Duzce Public Hospital in 2011-2012 for AUB and who underwent EC were included. We determined the reasons for AUB, and females with hyperplasia were treated with 10 mg/day medroxyprogesterone acetate for 14 days/month or 160 mg/day megestrol acetate continuously for 3 months. We evaluated the efficacy of progestins for periods of three and/or six cycles by repeating EC. A statistical analysis of specific endometrial causes according to age of presentation was conducted using the chi-square test. Results: Among the 415 females (average age, 53.5 years) followed for 6 months, 186 had physiological changes (44.8%), 89 had simple hyperplasia (21.44%), 1 had atypical hyperplasia (0.2%), 6 had (1.44%) complex hyperplasia, 3 had (0.72%) atypical complex hyperplasia, and 5 had adenocarcinoma (1.2%). Regression rates were 72.7-100%, and the optimum results were observed after 6 months of hormonal therapy. Conclusions: The main cause of AUB was physiological change. Progestin therapy resulted in significant regression even in females with atypical hyperplasia.

Objectives : Ryodoraku is a physiological function test using electric current, and is closely related to skin sympathetic tone. Pulse analysis is known to reflect cardiovascular reactivity. There has been no report on the correlation between ryodoraku and pulse analysis in respiratory diseases. The present study examined the diagnostic values of ryodoraku and pulse analysis for respiratory disease patients Methods : For this study, we conducted ryodoraku and pulse analysis in 103 people including 79 respiratory disease outpatients who visited the $5^{th}$ Internal Department of the Oriental Medicine Hospital of Kyung Hee University during the period from January 1, 2003 to July 25, 2006, and 24 volunteers who did not have any respiratory symptoms or disease history. The respiratory disease patients were divided into five sub-groups according to their symptom: cough-sputum group, wheezing-dyspnea group ' nasal symptoms group. cold-prone group, and fatigue prone group. We compared the disease groups with the control group in six items as follows : mean ryodoraku, mean H1, mean elastic index, the percentage of those with mean ryodoraku below $40{\mu}A$, the percentage of those with HI beyond the physiological range, and the ratio of left : right of elastic index Results and Conclusions : Ryodoraku and pulse analysis were found to have a high value as quantitative diagnosis tools reflecting individuals' weakness and firmness. The results of this research suggest that ryodoraku and pulse analysis have value as tools for diagnosing respiratory diseases.

Anorexia is a common symptom in the elderly patients. Causes of anorexia in the elderly are very diverse and multifactorial. Causes include physiological changes associated with aging, mental disorders such as depression, anorexia tardive, dementia, medical diseases such as cancer(lung and gastrointestinal cancer), benign gastrointestinal disorders, cardiac disorders, pulmonary disease, thyroid disorders, infection. Medications such as digoxin, theophylline have also been implicated in the problem. No cause is found in about one quarter of patients. Management is directing at treating causes and providing nutritional support. In Oriental medicine, the appetite has close relation to Biwi. The main cause of anorexia is the insufficiency of Biwi. The physiology of Biwi is that Bi sends clarity(food essence) upward and Wi sends digested food downward. Specially if the physiologic function of Wi is disordered by various factors, Wi cannot send digested food downward. As a result, the anorexia can present by the disorder of Wi function. We experienced a case of an 74 years old female patient with ill-defined severe anorexia differentiated as Wijoongheohan. The patient was managed with fluid therapy and Jeonghyangsiche-tang. The anorexia and other symptoms improved continuously during hospitalization.

Shrimps infected with WSSV(White Spot Syndrome Virus) generally exhibit white spots in their inner space of carapaces as an acute clinical sign. In an effort to identify the correlation between this acute clinical sign and the condition, the index factors (RNA/DNA concentration and ratio, trypsin activity) were analyzed. A total 580 farmed Fenneropenaeus chinensis and 130 Lithopenaeus vannamei were collected from western and southern fifteen outdoor ponds in Korea. The status of the white spot pathology was divided into four stages (stage 0, stage I, stage II, and stage III), in accordance with the clinical signs as to the size and area of white spots. A significant decrease in RNA concentration and RNA/DNA ratio for multi-infected fleshy prawn (WSSV and vibrio sp.) occurred during the stage III (the whole carapace is covered with a white spot). In particular, RNA/DNA ratio was significantly lower as $1.47{\pm}0.04$ than other groups. A similar trend was also found in the single infection (WSSV), but the decrease was less than the multi-infection. In the species comparison, both species were vulnerable to the multi-infection, but L. vannamei was more sensitive than F. chinensis(ANOVA, p<0.05): A significant decrease in RNA concentration and RNA/DNA ratio was first found in stage II for the former species, while it was found in stage III for the latter species. Trypsin activity was also showed a similar tendency with nucleic acid variation. Multi-infected shrimp showed drastically decrease of trypsin activity. According to the results, clinical signs of the white spot under carapace have an only physiological effect on shrimp if they covered entirely with white spots.

This study was carried out to provide basic information on physiological changes of 4-year-old seedlings of Pinus thunbergii inoculated with pine wood nematodes by analyzing changes of symptom development, stem and needle water content and nematode populations in stem. Twenty days after inoculation, needles were discolored as an external symptom, and xylem drying and pith browning occurred at the above and below of the inoculation sites as an internal symptom. However, xylem drying began to occur 10 days after inoculation, which was determined by the difference in drying status of xylem and cortex between control and inoculated seedlings. Although population of pine wood nematode increased from 5 to 10 days after inoculation, it has increased dramatically from 10 to 20 days after inoculation when both internal and external symptoms appeared. As the time passed by after inoculation with pine wood nematodes, water content of stem and relative water content in current needles and branch gradually decreased. As the number of nematodes increases, water content of stem and relative water content of current needles and branches decreased significantly. There was a positive relationship between the number of nematodes and xylem drying and/or disease development, but the number of nematodes rapidly decreased as seedlings become severely diseased.

To study the cause of physiological disorder in leaf of ginseng cultivated at paddy soil, the degree of brown-colored symptom (BCS) and the contents of inorganic matter in leaf were investigated by irrigating the solution of ferric and ferrous iron of 0.1 ~ 2.0%, and citric acid of 1.0 ~ 4.0% on bed soil, respectively. Ratio of BCS by variety was as high as 85.0% in Yoenpoong, while it was as low as 5.4%, 7.5% in Chunpoong and Hwangsook, respectively. The contents of inorganic matter of leaf in Yoenpoong were lower in $P_2O_5$, Ca, and Mg, while it were higher in K, Fe, and Mn than other variety. Iron solution caused BCS more distinctly when each ferric and ferrous iron were dissolved with 1.0% citric acid than when each iron was dissolved without citric acid. Ferric iron caused BCS more effectively than ferrous iron. BCS occurred in 4.0% citric acid was as same as 2.0% ferric iron mixed with 1.0% citric acid. Low $P_2O_5$ and high Fe content in leaf appeared in both of artificial and natural symptoms. We concluded that excessive Fe uptake caused BCS to leaf because the solubility of iron was increased in condition of low soil pH.
