This study was aimed to get the course which is caused by Neuropsychiatric symptoms in Sang-Han. Therefore this study is based on 『Euhak-Ipmun. Sang-Han』(『醫學入門.傷寒』) classfied mainly by symptoms. The results were summerized as follows: 1. Neuropsychiatric symptoms in 『Euhak-Ipmun. Sang-Han』(『醫學入門. 傷寒』) are explained as Pal-Gang(八綱), which shows those are settled down to a systematic oriental medical theory. 2. Pal-Bup (八法) used in the cure of symptomatische psychose in 『Euhak-Ipmun. Sang-Han』(『醫學入門. 傷寒』), which is intended to boost the effect of cure, choosing the respondent cure method about various causes. 3. Pal-Gang(八綱) and Pal-Bup(八法) in『Euhak-Ipmun. Sang-Han』(『醫學入門·傷寒』) are improved by Lee-Chun(李 ) who added Jang-gi(張機)`s Sang Han theory and new medical thought in the ages of Geum. Won. 4. Lee-Chun(李 ) believed that Neuropsychiatric symptoms which appeared in Sang Hang is caused by the Unbalance(不平). So he wanted to reach harmony of Jeong(精), QI(氣), Shin(神), Hyul(血) after improving the status of Unbalance(『不平』) toward the status of Balance(平).

These days, SFCLs are being developed in order to limit fault current. However, the superconducting elements that limit the fault current have such problems as capacity increase and require auxiliary devices including cooling device. If devices that comprise the current power network can withstand fault current for at least one cycle, it is possible to limit the fault current with current limiting elements by bypassing it on the fault line. In this study, the fault current limiter was configured with current transformer, vacuum interrupter, and current limiting element. Through the experience, it was confirmed that the fault current was limited within one cycle. The superconducting element, as a current limiting element, limited the fault current by 80 % within one cycle from fault occurrence, and the passive element limited it more than 95 %. Also, through the comparison between resistance curve and power consumption curve, it was confirmed that the current limiting element using a passive element was more stable than the superconducting element that required capacity increase and other auxiliary devices. It was considered that the FCL proposed in this study could limit fault current stably within one cycle from fault occurrence by using the existing power technologies such as fault current detection and solenoid valve operating circuit.

Background : Dementia, a prevalent condition among the elderly, has emerged as a significant social issue in South Korea due to the nation's aging population. Given the absence of a cure for dementia, early detection and proactive prevention measures are crucial. This study seeks to evaluate the efficacy of an artificial intelligence (AI) chatbot-based mobile health (mHealth) application, specifically designed for the early detection and customized cognitive enhancement training for dementia prevention.<BR/>Methods : A total of 123 older adults from rural South Korea were randomly assigned to an intervention group (n = 84) or a control group (n = 39). The intervention group participated in a 6-week cognitive assessment and customized cognitive enhancement training app, and an AI chat- based motivational program, while the control group engaged in traditional offline dementia prevention programs such as art therapy, exercise, and group singing. The study evaluated whether the intervention group showed greater cognitive improvements. The analysis also examined app usage frequency, adherence rates, and differences in cognitive improvement between heavy and light users, as well as between cognitively normal and cognitively impaired participants. Interviews were conducted with participants, and both quantitative and qualitative analyses were employed to evaluate the outcomes.<BR/>Results : The results of the study demonstrated significant improvements in cognitive performance among the intervention group, whereas no statistically significant improvement was observed in the control group. Among the intervention group, both cognitively impaired and normal groups showed improvement in the cognitive function, with a larger effect in the impaired group. Higher app usage was linked to greater cognitive improvement. Engagement with the app increased over time, particularly influenced by daily mission reminders and chat-based gameplay, while awarding prizes did not impact user engagement.<BR/>Conclusions : This study demonstrates the effectiveness of an AI chatbot-based mHealth application, specifically designed for early screening and customized cognitive enhancement training for dementia prevention in older adults. The study presents a novel approach to prevent dementia among older adults.

복부 결핵으로 발현된 후천성 면역 결핍증 1예

The incidence of tuberculosis (TB) had gradually been declining all over the world, but in recent years, TB has been increasing due to the spread of the human immunodeficiency virus (HIV). When immune-suppression status deteriorates further, extrapulmonary TB generally appears more often. Abdominal TB is one type of extra-pulmonary TB, which may involve the gastrointestinal tract, peritoneum, lymph nodes or solid viscera. We encountered a case who had initially been diagnosed as having abdominal TB, had progressed to acute respiratory distress syndrome and was eventually confirmed as having developed acquired immune deficiency syndrome. In cases of coinfection of TB and HIV, it is reported that immunological responses become poor and complications with higher morbidity frequently occur. Therefore, the Korean guidelines for TB should be revised to ensure whether HIV infection exists in TB patients.

J.M.Keynes의 一般理論 小考 : 그 理論分析을 中心으로

成炳卓 대구교육대학교 1968 論文集 Vol.4 No.-

In this paper, I have attempted to explain the distinctive features of the General Theory of J. M. Keynes. The distinctive features of it may be stated in the form of the following propositions. Total income depends on the volume of total employment. According to the propensity to consume, the amount of expenditure for consumption depends on the level of income, and therefore depends on total employment. The total employment depends on the total effective demand, which is made up of two parts: consumption expenditure and investment expenditure. In equilibrium, the aggregate demand is equal to the aggregate supply. Therefore the aggregate supply goes beyond the effective demand for consumption by the amount of the effective demand for investment. In equilibrium, the aggregate supply is equal to the aggregate demand, and the aggregate demand is determined by the propensity to consume and the volume of investment. Therefore, the volume of employment depends on the aggregate supply function, the propensity to consume, and the volume of investment. Both the aggregate supply function. which depends mainly on the physical condition of supply, and the propensity to consume are relatively stable and therefore the fluctuations in employment depend mainly on the volume of investment. The volume of investment depends on the marginal efficiency of capital and the rate of interest. The marginal efficiency of capital depends on the expectations of profit yield and the replacement cost of capital assets. The rate of interest depends on the quantity of money and the state of liquidity preference. In brief, the theoretical frame of the General Theory of J.M. Keynes is made up of the above propositions which are explained in relation to each other in my paper.

Obesity may cause metabolic syndrome and adult diseases. This study was undertaken to investigate the ameliorative or useful effects of beanleaves on inflammation and liver damage in obese rat models. Rats were divided into three groups: a control group (normal diet, n=6), a fat diet group (45%?fat diet, n=7), and a bean leaf group (45%?fat+Korean bean leaves diet, n=7). Body weights in the bean leaf group were lower than those of the fat group (P<0.05). Serum tumor necrosis factor?α (TNF?α) and prostaglandin E₂ (PGE₂) concentrations were lower in both the control and bean leaf groups than in the fat group (P<0.001). TNF?α concentrations in the bean leaf group were slightly higher than in the control group but statistically significant (P<0.05). The bean leaf group histologically exhibited lower fatty degeneration, spotty necrosis, and leukocyte infiltrations in hepatic tissues than those of the fat group. In the homogenized liver tissues, the cyclooxygenase?2 (COX?2) gene was only expressed in the fat group. The gene expression levels of hepatic TNF?α, inducible nitric?oxide synthase, peroxiome proliferator?activated receptor?α (PPAR?α), poly (ADP?ribose) polymerase (PARP), and transforming growth factor?β1 (TGF?β1) were weaker in the bean leaf group than in the fat group. These results suggest that adding bean?leaves to the diet may ameliorate obesity?induced systemic inflammation and liver damage and that bean leaves may be a useful food for preventing obesity and thereby metabolic syndrome and adult diseases

GPS/INS를 활용한 항공 정사영상 제작에 관한 연구

박병욱,이창재,서상일 한경대학교 2008 論文集 Vol.40 No.-

In this study we took the aerial photos scaled 1:5,000 with aircraft equipped GPS/INS. DEM was generated by automatic image matching method using the exterior orientation parameters obtained by GPS/INS, and the ortho-images were produced by differential rectification based on that. As the result of measurement of RMSE based on digital map for ortho-images produced with GPS/INS data, the horizontal position error was 61cm that was good enough to satisfy the precision demand of 1:1,000 ortho-image map. There were no big differences in precision of ortho-images between GPS/INS and aerial triangulation process. It seems that the producing method of ortho-image using GPS/INS data can be speedier and more efficient method than traditional method using aerial triangulation
