Objective: This study was performed to investigate the effect of acupuncture at HT8 on brain activity in perimenopausal women using fMRI. Methods: 15 healthy perimenopausal women volunteered in the study. No stimulation, sham stimulation, duration of acupuncture treatment on HT8, and rotation of acupuncture treatment on HT8 were randomly given for 6 minutes, with 20 seconds' intervals. Results: 1. In comparison with sham stimulation(Sham-B) and duration of acupucture (S1-B, S1-Sham, S2-S1), the areas of fMRI signal activation areas were just like cases including no stimulation. But the areas of vision were activated in S1-Sham. 2. In comparison with duration of acupuncture(S1-B, S1-Sham, S2-S1) and rotation of acupuncture(S2-B, S2-Sham, S2-S1), the areas of vision were activated in duration of acupuncture, and Supplementary motor area(SMA) were especially activated in rotation of acupuncture. Conclusions: After using fMRI and analysing effect of acupuncture treatment at HT8, we could confirm that fMRI signal activation areas by acupuncture treatment at HT8 were different from areas by sham stimulation. And according to acupuncture stimulation methods with duration and rotation, etc, we could confirm the specific reactions of series, and could get useful basic data for research of acupuncture from now on.

Objectives: This study was conducted towards developing a screening tool for syndrome differentiation in the diagnosis of menopause in menopausal and perimenopausal women. Methods: We conducted a literature review of studies on menopausal diagnosis based on syndrome differentiation, and examined well-founded differentiated syndromes and their respective clinical symptoms. Based on the findings, we created a questionnaire through consultations with Oriental medicine experts in physiology, pathology, and diagnostics. Finally, the research team conducted an expert Delphi study on differentiated syndromes and the associated clinical symptoms. Results: Seven differentiated syndromes were selected, including Liver Depression (肝鬱), Kidney Yin Deficiency (腎陰虛), Kidney Yang Deficiency (腎陽虛), Liver and Kidney Yin Deficiency (肝腎陰虛), Kidney Yin and Yang Deficiency (腎陰陽兩虛), Heart-Kidney Noninteraction (心腎不交), and Dual Deficiency of Heart and Spleen (心脾兩虛); 4 disease locations, including liver (肝), heart (心), spleen (脾), and kidney (腎); and 3 disease natures, including Yin Deficiency (陰虛), Qi Stagnation (氣滯), and Blood Deficiency (血虛). In addition, we added 3 supplemental disease natures, including Yang Deficiency (陽虛), Qi Deficiency (氣虛), and Heat (火熱), in consideration of syndrome differentiation categories that may possibly be added in a follow-up clinical questionnaire. Conclusions: This resulted in a total of 7 differentiated syndromes, 4 disease locations, and 6 disease natures. We translated the clinical symptoms of these 17 categories into Korean Hangeul. After consulting with 5 Oriental medicine experts and a psychology expert, we produced a questionnaire for use in diagnosing menopause based on syndrome differentiation. The calculation of scores for the syndrome differentiation screening tool will be confirmed through clinical research based on the results of a review of existing literature.

Nach der sog. Neue Influenza(Schweinegrippe)-Pandemie wird die Verh$\ddot{u}$tung und Bek$\ddot{a}$mpfung von Infektionskrankheiten eine essentielle Aufgabe f$\ddot{u}$r das Gemeinwesen und stellt eine komplexe Herausforderung f$\ddot{u}$r die Rechtsordnung dar. Die n$\ddot{a}$chste Pandemie ist nicht mehr eine Frage der Ob, sondern lediglich der Zeit. Zwar ist der jetzige Influenza-Pandemie Plan und der koreanische Infektionsschutzgesetz (ISchG) nicht verfassungswidrig, weil mit ihnen die Untergrenzen des Gestaltungspielraums von Gesetzgeber nicht unterschreitet und damit die grundrechtliche Schutzpflicht von Staat nicht verletzt ist. Jedoch ist aber gesetzlicher Erg$\ddot{a}$nzung bed$\ddot{u}$rftig, denn es gibt keine konkrete Regelungen, die in einer Verknappungssituation von medizinischen G$\ddot{u}$tern bei Pandemien anwendbar sind. W$\ddot{u}$rde die Knappheit von Impfstoff nicht vermeiden, dann d$\ddot{u}$rfte dar$\ddot{u}$ber entschieden werden, wem die Ressourcen in der Verwendungskonkurrenzen bevorzugt zugeteilt werden sollen. In Knappheitssituationen ist zuerst die Frage der Verteilung medizinischer G$\ddot{u}$tern von so wesentlicher Bedeutung, dass sie von Verfassungs wegen durch das Parlament zu regeln ist. Zweitens kann die Verteilung knapper medizinischer Ressourcen auf Maximierung der Uberlebendenzahl als Menschenw$\ddot{u}$rdegrundsatz und Lebensschutzpflichten vom Staat gerichtet sein. Drittens d$\ddot{u}$rfen die in Art.11 KVerf genannte Kriteien, wie Geschlecht oder Religion, weil sie als Ungleichbehandlungskriterium im koreanischen Verfassungstext verboten sind, nicht zur Verteilung und Zuteilung herangezogen werden. Nicht zuletzt darf und muss der Gesetzgeber dar$\ddot{u}$ber regeln, wer in welchem Verfahren behandelt bzw. gesch$\ddot{u}$tzt werden soll.

In order to establish the manifestational symptoms in men and women and highly frequent symptoms(HFS) of deficiency of Qi and blood(氣虛, 血虛), stagnation of Qi(氣滯), deficiency of Yin(陰虛), deficiency of Yang(陽虛), and, 546 questionaires were analyzed through Cronbach alpha value and Pearson's correlative efficient. Symptomatic differences of male and female specimens were as follows. HFS of Qi deficiency were similar in terms of inactivity like mental and physical fatigue, enervation in men and women. In blood deficiency, dizziness and light sleep were common in men and women, but mucosal symptoms of conjunctiva, lip, nail bed were more frequent in women than men. Emotional explosion was common in Qi stagnation, then women had more motivation-related symptoms than men. Inner heat was frequently arisen in Yin deficiency in both, and the heat was expressed more common in exterior and upper part in women but in interior abdominal part in men. In Yang deficiency, main symptoms of men were feeling coldness in peripheral, but Qi deficiency symptoms were more common in women former than coldness.

Two new azobenzene crown ether calix[4]arenes, 10 and 11, were synthesized by two pathways. In the first pathway,two ethoxy nitrobenzene groups were attached to t-butylcalix[4]arenes in a 1,3 position. Subsequent reduction ofthe nitrobenzene group s by metallic zinc in an alkaline solution afforded 10 and 11 in8% and 12%,respectively. In the second pathway,an azobenzene containing two glycolic units was prepared prior connect-ing to t-butylcalix[4]arenes. The yields from the second approach (5%, 8% for 10 and 11, respectively) were lower than those from the former approach. Single crystals of 10 suitable for X-ray crystallography was ob-tained by recrystallization in methanol.Both the X-ray structure and the 1H-NMR spectrum of 10 indicated that the stereoisomer of the azobenzene moiety was trans and the calixarene platform was in cone conformation. 1H NMR spectroscopy suggested that 10 underwent an observable cis-trans isomerization in CDCl3 under room light and upon UV irradiation with cis:trans ratios of 33:67 and 36:64,respectively. Compound 6 which was the precursor of 11showed fluxional behavior and was found to have mixed conformations ofcone and partial cone with a ratio of 47:53 at -30 $^{\circ}C.$ 1H NMR spectrum of 11 suggested that 11 was initially isolated as cis azobenzene with calix[4]arene in cone conformation and underwent conformational interconversion through calix[4]arene annulas in a similar fashion to 6 upon exposing to light. The complexation studies of 10 with picrate salts of Na+ and K+ using 1H NMR spectroscopysuggested that Na+ preferred to bind the cis form of 10 while K+ preferred to bind the trans form. The stereoisomer of the azobenzene unit in 11 changed partially from cis to trans upon complexing with K+.

Objectives: This study was aimed to develop a guideline for the application of diagnostic devices for menopausal syndrome. Methods: We conducted a literature review and a questionnaire survey on diagnostic devices including Digital Infrared Thermal Imaging (DITI), pulse diagnosis device, Heart Rate Variability (HRV), body composition analyzer, Yangdorak. Results: We retrieved some clinical values for usage of devices from the articles. Especially, DITI was useful to identify the pattern of body temperature distribution. The respondents answered that they diagnosed menopausal syndrome by using body composition analyzer (62.3%), DITI (60%), HRV (60%), pulse diagnosis device (45.7%), Yangdorak (34.3%). The respondents answered that they don't use diagnostic devices when they diagnosed menopausal syndrome because of absence of device, cost, difficulty of interpretation, substitution of another diagnostic method. After experts survey, it was recommended to use DITI, HRV, body composition analyzer. There was no consensus on the use of pulse diagnosis device, Yangdorak in diagnosing menopausal syndrome. Conclusions: We developed a guideline for the application of diagnostic devices for menopausal syndrome.

Objectives: We conducted a literature study on the treatment trends in China to find out the possibility of Oriental medicine treatment of atypical hyperplasia of breast (AHB). Methods: RCTs (randomized controlled trial) on AHB were collected from CNKI (China National Knowledge Infrastructure). The search words were "乳腺增生", "乳腺囊性增生", "乳癖", "中医", "中药" and "中西医结合". The search period was limited from July 2006 to May 2017. Finally, we selected 107 RCTs which were clinical studies to find out the effectiveness of Chinese herbal medicine in comparison with Western medicine. After reviewing, we investigated Chinese herbal medication guide, Chinese treatment method and prescriptions. And the correlation between the treatments and the medicinal herbs was investigated to be useful in the clinical practice. Results: 1. The administration of herbal medicine was 58.9 percent in 63 cases, followed by menstrual cycles, and 41.1 percent in 44 cases, regardless of menstrual cycles. 2. In the basic frequency analysis between the treatment and the medicinal herb, the frequency of dissipate binds (散結) was the highest. Next, there was a high frequency of therapies such as activating blood-activating (活血), relieve pain (止痛), soothe the liver (疏肝), regulate qi (理氣), resolve phlegm (化痰), soften hardness (軟堅), resolve depression (解鬱), move qi (行氣) of frequency was high. In herbal medicine, bupleuri radix (柴胡), cyperi rhizoma (香附子), angelicae gigantis radix (當歸), fritillaria thunbergii bulb (貝母), paeoniae radix alba (白芍藥), prunellae spica (夏枯草), corydalis rhizoma (玄胡索) showed high frequency. 3. We finded out the correlation between the frequent treatment methods and the medicinal herbs using Text Mining. Conclusions: These findings are thought to help implement Korean traditional medicine treatments for AHB.

Background: Exposure to air pollution (gaseous pollutants and/or particulate matter) has been associated with the incidence, prevalence, and mortality of type 1 diabetes (T1D). Purpose: To examine the quantitative relationship between air pollutant emissions and the incidence of T1D. Methods: We examined the association between the incidence of T1D and type 2 diabetes (T2D) in 2017 as well as that of T1D in patients younger than 15 years in 2016 with "emissions of air-polluting substances from stationary and mobile sources by regions of the Russian Federation in 2016" as reported by the Federal Diabetes Register of Russia downloaded from the Russian government website (http://www.mnr.gov.ru/docs/gosudarstvennye_doklady/o_sostoyanii_i_ob_okhrane_okruzhayushchey_sredy_rossiyskoy_federatsii/). Results: The incidence of T1D across all ages in each region of the Russian Federation correlated with the total air pollutants emitted in the region each year (r=0.278, P=0.013). The incidence of T2D was also correlated with the amount of air pollutants (r=0.234, P=0.037) and the incidence of T1D (r=0.600, P<0.001) in each country. Similarly, the incidence of T1D in patients younger than 15 years correlated with the total air pollutants emitted each year in each region (r=0.300, P=0.011). Conclusion: The quantitative relationship between the total air pollutants emitted and the incidence of T1D and T2D in the Russian Federation suggests that air pollution contributes to the development of T1D and T2D.

This study was performed to find antibacterial substances contained in Scutellariae Radix (SR) using a systems pharmacological analysis method and to establish an effective strategy for the prevention and treatment of infectious diseases. Analysis of the main active ingredients of SR was performed using Traditional Chinese Medicine Systems Pharmacology (TCMSP) Database and Analysis Platform. 36 active compounds were screened by the parameter values of Drug-Likeness (DL), Oral Bioavailability (OB), and Caco-2 permeability (Caco-2), which were based on the drug absorption, distribution, metabolism, and excretion indicators. The UniProt database was used to obtain information on 159 genes associated with active compounds. The main active compounds with antibacterial effects were wogonin, β-sitosterol, baicalein, acacetin and oroxylin-A. Target proteins associated with the antibacterial action were chemokine ligand 2, interleukin-6, tumor necrosis factor, caspase-8,9 and mitogen-activated protein kinase 14. In the future, systems pharmacological analysis of traditional medicine will be able to make it easy to find the important mechanism of action of active substances present in natural medicines and to optimize the efficacy of medicinal effects for combinations of major ingredients to help treat certain diseases.

It has recently been noticed that the headway of unlicensed wireless technology is necessary as user's demands of wireless tech increase and the development of high-speed data service by using low-power short-range wireless network is needed. Hence, it is inevitable to study sharing and coexistence for broadband spectrum of diverse unlicensed application with wide bandwidth. In this paper, an interference examination between unlicensed WiFi (Wireless Fidelity) in the 6GHz and OB (Outside Broadcasting) system which is an incumbent service in the same frequency band was conducted and it suggests separation distance for the coexistence. Thus, MCL (Minimum Coupling Loss) and MC (Monte Carlo) methods were used to set up interference scenarios for the interference analysis and compute the separation distance between two systems according to the same frequency band and frequency separation.
