Objective : The purpose of this study is to analyze the naming of 'A diagnostic system based on Shanghanlun six meridian patterns and provisions' and to suggest an alternative naming. Methods : 1. The meaning of 'Six meridian(六經)' was reviewed on existing theories and Shanghanlun provisions. 2. Comparing the name of diangostic system with the term in 'Korean Standard Classification of Diseases-6(KCD-6)' and term in 'WHO international standard terminologies on traditional medicine in the western pacific region' was done. Results : 'Six meridian' is customary used in the Shagnhanlun study but its meaning is not match with original Shanghanlun system and could possibly make misunderstanding. So 'Disease pattern identification' is suitable than 'Six meridian' for this diagnostic system. Conclusions : This study suggests that using 'A disease pattern identification diagnostic system based on Shanghanlun provisions.'is more appropriate instead of using the name of the six meridian diagnostic system.

Carbon nano tubes(CNTs) have been reported as field emission source because has a sharp tip, a high aspect tip, high chemical stability, high mechanical strength and low work function properties. In this study, we fabricated successfully the back-lamp of the I-inch flat type using CNTs, which was grown directly on cathode substrate of sodalime glass at low temperature. The brightness of CNT back-lamp is measured to $14 Kcd/m^{2}$ at $2000V_{dc}$ in spacing of $500{\mu}m$. And, the emission properties of packaged CNT back-lamp was analyzed as function of applying voltage and times.

We fabricated the 1-inch diode type flat lamp using CNTs, which were grown directly on soda-lime glass substrate at 600 ∼ 650 $^{\circ}C$ by thermal chemical vapor deposition(CVD) of acetylene gas. Turn- on field was about 2.8 V/${\mu}{\textrm}{m}$. We observed that uniform and high brightness had been obtained. The brightness of CNT flat lamp was measured up to about 14 kcd/$m^2$ at 2000V in spacing of 500 ${\mu}{\textrm}{m}$. The results showed that the CNTs were very good emission source and suitable for application in the lamp.

Objectives : This study is retrospective chart review research on the combined-prescription of Western and Korean medicine in Public Health Center in rural area. Methods : Researchers reviewed medical records of patients who was prescribed Korean medicine and Western medicine from 1st, Jan, 2019 to 31st, Dec, 2019 in Public Health Center. 50 patients' medical records were included. Results : Total number of treatment is 3,808 cases and 1.3% of them is prescribed Korean medicine and Western medicine simultaneously. Prescription of Korean medicine is 153 cases and Western medicine is 160. Jowiseunggi-tang and Diroba tablet were the most frequently prescribed Korean medicine and Western medicine. Furthermore, Korean Medicine Doctors of Public Health Center use muscular skeletal disease system code(M code among KCD code) for prescription and Western Medicine Doctors use diseases of the circulatory system(I code among KCD code) frequently. Conclusions : We analyze 50 patients who were prescribed both Korean medicine and Western medicine. Mostly, patients were prescribed medicine for different diseases in each clinic. In western medicine clinic, drugs about circulatory or endocrine disease were prescribed frequently and in Korean Medicine clinic, drugs about muscular skeletal disease were most frequently prescribed. This result imply the real world's combination of prescription status that was different from result of National health insurance corporation database. Senior patients in rural area take medicine long period and have various underlying disease. We call for some attention about senior and rural area patients' prescription status in interaction studies of Korean medicine and Western medicine.

This study was designed to investigate the effects of plum(Prunus salicina Lindl. cultivars 'Oishiwase', 'Formosa', and 'Soldam') extracts on the proliferation as well as inhibition of human epithelial cells(HaCaT), human cervical carcinoma (HeLa, SiHa, and C33A) cells, and human stomach adenocarcinoma(SNU 638) cells. Dried plum was sequentially extracted and fractionated by hexane(KC-01), chloroform(KC-02), ethyl acetate(KC-03), n-butanol(KC-04), water(KC-05), methanol(KC-6), and hot water extract(KC-07). The epithelial and cancer cells were exposed for 48 h to $50{\mu}g/mL$ of plum extract in vitro, and were then analysed by a sulforhodamin B(SRB) staining assay. The methanol extract(KCP-6) of 'Formosa' proliferated not only the HaCaT cells(147.3%), but also the cervical carcinoma C33A cells(167.8%). The ethyl acetate extract of 'Soldam'(KCJ-3) significantly reduced the proliferation rate of the HPV positive conical carcinoma cells, at 61.5% for the SiHa cells and 70.5% for the HeLa cells. In the C33A cells, which are HPV negative cervical carcinoma cells, the hexane fractions of 'Formosa'(KCP-1) and 'Oishiwase'(KCD-1) markedly suppressed proliferation activity at 20.4% and 61.7%, respectively. However, the proliferation rate of the normal epithelial cells(HaCaT cell) was not reduced the proliferation rate by KCJ-3, KCP-1, or KCD-1, There were no significant effects on proliferation of the stomach cancer cells(SNU 638) by any of the extracts or fractions of the plum cultivars. These results suggest that the anti-proliferative effects of the plum cultivars were selective to the cancer cell origin. In conclusion, we found that several plum cultivar extracts, especially, the ethyl acetate fraction of 'Soldam" and the hexane fraction of "Formosa', have anti-proliferative activity toward human cervical carcinoma cells. However, further investigation is needed to assess the molecular mechanisms that mediate the antiproliferation activities of the plum cultivars.

Objectives : The aim of this study is to give a statistical basis for the characteristics of patients who received cooperative medical care after being referred from Western medical departments to the Department of Acupuncture and Moxibustion in a Korean medical hospital. Methods : The request records were searched for cooperative medical treatment at the Department of Acupuncture and Moxibustion in a Korean medical hospital between September 1st, 2011 and August 31, 2016, based on the Order Communication system(OCS). The records were reviewed and retrospectively analyzed according to the patient's general characteristics, the chief diagnosis code based on the 7th Korean standard classification of diseases(KCD-7) before and after the cooperative medical care in the Department of Acupuncture and Moxibustion, and the actual treatment measures which patients received as a result of the cooperative medical care. Results : Among the 2702 records, 1549 patients were included in the analysis. The male to female ratio was 1 : 1.17. Sexagenarians formed the highest age group and the number of patients whose age was over 50 was 1176(75.92 %). The surgery department requested the cooperative care from the department of Acupuncture and Moxibustion for the highest number of patients, 1194(77.08 %). When analysing specific medical departments, Neurosurgery, General Surgery, Neurology, Otorhinolaryngology, and Physical medicine and rehabilitation followed. The frequency of chief diagnosis code used before the cooperative medical care was in the order of I, C, G, S, and M code, from highest to lowest. The order of the codes after the cooperative medical care was the same. Acupuncture treatment was the most frequently-used measure after the cooperative medical care. Following were infrared, moxibustion, transfer, herbal acupuncture, cupping, electroacupuncture, and so on. Conclusion : This study provides a statistical basis for the demands placed on the Department of Acupunture and Moxibustion for cooperative medical care with the Western medical department. Based on the present condition of cooperative medical care, more preparation and effort is required for its activation.

Purpose: This study reports the clinical features of infant, child, school aged and adolescent patients treated for acute poisoning in nationwide emergency departments (EDs). Methods: We retrospectively analyzed clinical data pertaining to patients under 19 years of age who were treated for acute poisoning in nationwide EDs from 2013 to 2015. The data were collected by the National Emergency Department Information System (NEDIS). All patients were divided into three groups: 'Infant and child group' (0 to 5 years), 'school age group' (6 to 12 years) and 'adolescent group' (13 to 18 years). General characteristics, Korea Standard Classification of Disease $7^{th}$ (KCD-7) codes and results of care were collected. Results: There were 14,500 pediatric poisoning cases during the study period. The distribution of patient age was bimodal with two peaks among infant, child and adolescent group. The proportion of alert mentality at the ED visit of the infant and child group was 99.3%, while that of the adolescent group was 86.4%. The proportion of intentional intoxication was higher in the adolescent group (40.7%) than other age groups. Among children less than 13 years of age, various poisonous substances and therapeutic drugs were common. Conclusion: There were some clinical differences in acute poisoning patients between age groups. It is necessary to establish a preventive plan considering characteristics by age. Since the KCD-7 code has limitations in analyzing the characteristics of poisoning patients, it is necessary to consider the registration system of poisoning patients.

This study aims at deriving any useful information necessary to strengthen the competitiveness for growth through empirical analyses on general hospital located in a province in order to countermeasure the opening and competition of medical markets. The characteristics of user were identified on the basis of disease groups under KCD in the research method. In addition, the analysis on the expenses of diagnosis and treatment was divided into the treatment progress and degree of hospital resource utilization And the regression was carried out to identify the impacts of characteristics of inpatient users on the degree of hospital resource utilization. As a result of major research, the inpatient users of the general hospital located in the provincial area in consideration of inpatient users were formed around the inpatient disease groups representative for Korea(diseases of the respiratory system, injury and poisoning & certain other consequences of external causes). And it was understood that most of residents within a distance of 40 minute by the public transportation were using. And mostly were under the age of 9 or over 60, and the provision of medical features such as the degree of consultation and operational functions were inadequate. When we classify inpatient treatment cost for each resource application as the medical cost being the center of patient care function, the equipment and human resource application sector are constituted over half. Accordingly, the following suggestions are made as plans to strengthen the competitiveness for the growth of general hospitals located in the provincial areas on the basis of analytical results. First, it is necessary to have the characterization matching to the age and disease groups with a high frequency. Second, it is necessary to increase the degree of hospital resource utilization according to the characterization. Third, it is necessary to concentrate on public relations. The above suggestion, as a method for securing image improvement and competitive power as a general hospital, and through expansion of social function that a regional general hospital needs to secure not only as an individual institution but also as a general hospital, it can be seen that a general improvement of image as a regional general hospital is possible.
