Objectives : This study was conducted to investigate current research trends in Chuna manual therapy for the treatment of anxiety disorders in China. Methods : Using China Academic Journal and Pubmed, we performed a literature search of studies that were published from 2010 onwards. In total, 15 published studies were included in our analysis. Results : Of the 15 analyzed studies, nine were randomized controlled trials, two were non-randomized controlled trials, and four were case reports. Of the total patients, 80% were treated daily and received ${\leq}30$ treatments in total (excluding one study). In most studies(11 out of 15, 73.33%), the total effective rate of treatment was used to measure the outcome, with the Hamilton Anxiety Rating Scale being used most frequently. The case report demonstrated a therapeutic effect > 90%. In the control study, except for the two studies that reported significant improvement in the follow-up period, all of the measures were significantly improved (P<0.05) after treatment compared with before treatment. The An(按) and Rou(?) methods were the most frequently used. The Chuna method is categorized into four types: 1) It is performed around shoulders, neck, and face; 2) performed around abdomen, back, and neck; 3) performed on the whole body; 4) performed at the simply-stimulated acupoints. The most commonly used acupoint was Taiyang (Ex-HN 5), and the most frequently used acupoints were predominantly distributed in the head, face, and neck. Conclusions : This study demonstrated that Chuna manual therapy has significant effects when used as a treatment for anxiety disorder, warranting further investigation.

This paper concerns a case study on the design concept, analysis, construction methodology of a subway tunnel excavated in the soft ground beneath an existing building where the distance between the bottom of the building and the crown of the tunnel is separated by about 3 meters only. The silot tunnels are excavated in advance, and side reinforced-concrete walls are installed. Then, main tunnels are excavated with ring cut method. The steel ribs are installed and supported by the side walls made in advance. Between the steel ribs and the side walls, the screw jack is installed to apply prestressing so that settlement can be controlled at minimum. Various in-situ seasurements are made and compared with computed values obtained by numerical methods. By choosing this underpinning method with very caraful construction control, tunnelling projects could be finished successfully without having any damage to the building located very closely to the tunnel crown.

The purpose of this study is to investigate the relations between marital status incompatibility and the ways of dealing with marital conflict. Research was conducted by interview using questionnaire on 177 employed wives. Statistics used for data analysis were frequency distribution, percentage, t-test, chi-square test. 1) In resolving marital conflict four types of method are appeared, namely constructive method, passive method, evasion and physical violence. 2) Only physical violence of husband-to-wife of the four methods is related to status in-compatibility. That is the incidence rate of physical violence of husband-to-wife in incompatible couples is higher than that of compatible couples in conflict situations. 3) In case the wife's occupational status is high relative to her husband the incidence rate of physical violence of husband-to-wife is extremely high, but is significantly low in couples which are compatible in this status. 4) In case wife's status advance ent is controlled, there is significant relationship between status incompatibility and the method of conflict resolution by husband whose wife is status striver.

The purpose of this study is to examine the characteristics of stress corrosion cracking(SCC) and acoustic emission(AE) signals for the weld HAZ of HT-60 steel under corrosion control in synthetic seawater. Corrosive environment was controlled by potentiostat, and SCC experiment was conducted using a slow strain rate test method at strain rate of 10$^{-5}$ /sec. In order to verify the miroscopic fracture behaviour of the weldment during SCC phenomena, AE test was done simultaneously. Besides, correlationship between mechanical parameters and AE ones was investigated. In case of the parent, reduction of area(ROA) at -0.5V was samller than any other applied voltage such as -0.8V and -1.1V. In addition, reduction of area for the PWHT specimens at -0.8mV was larger than that of the weldment due to the softening effect according to PWHT. In case of the weldment, a lots of events was produced because of the singularities of the weld HAZ compared with the parent.

This case study aims to embody the requirement of the make-to-order type manufacturer who wants to manage risks effectively when decisions are required to be taken under a risk. First, we present a method for choosing the risk factors that should be controlled for the make-to-order type manufacturer. Subsequently, those factors have been verified using statistical methods such as the ANOVA test. The process flows to be operated with the selected risk factors and the rules for an early warning system have been proposed. For a couple of factors, a prototype system has been developed to illustrate actual applications. Applications of the technique developed here for other types of manufacturers might be an interesting research problem.

Along with the rapid growth in microelectronics and power electronics technologies, various advanced control methods have been successfully implemented in real time and shown to be useful in controlling CO2 arc welding systems with high dynamic performance. In this paper, the slope of welding currents is controlled not to be so high in the case of short circuit welding mode. This results in less spatter. In addition, the data-base is constructed for the optimal welding conditions.

This paper presents a variable speed wind generation system where fuzzy logic controllers is used as efficiency optimizer. The fuzzy logic controller increments the machine flux by on-line search to improve the generator efficiency in case of light load. The speed of the induction generator is controlled according to the variation of the wind speed in order to produce the maximum output power The generator reference speed is adjusted according to the optimum tip-speed ratio. The complete control system has been developed by simulation study.

The Smoluchowski equations with a linear and a parabolic potentials in one-dimensional case are solved for the reflecting boundary condition. Analytic expressions for the long-time behaviors of the remaining probabilities are obtained. These results, together with the previous result for a step potential, show the dependence of the desorption process on the form of potential. The effect of the radiation boundary condition is also investigated for three types of potentials.

In case of oral application of quinupramine, antidepressants, it may cause adverse effects such as diarrhea, nausea due to transient high blood concentration. Ethylene vinyl acetate (EVA) which is heat-processible, flexible, inexpensive material was used for transdermal drug delivery. The purpose of this study was to develop the new transdermal delivery system of quinupramine using EVA polymer matrix that can provide sustained release and avoid the side effects. The EVA matrix containing quinupramine was prepared by solvent-evaporation method. (omitted)

Objectives: The purpose of this study was to summarize current research trends and results regarding acupuncture treatment for hypertension. Methods: Articles published from 2009 to 2019 were searched on domestic databases (OASIS, NDSL, RISS) and PubMed using the keywords 'Hypertension', 'Hypertensive', 'Acupuncture', 'EA' (electroacupuncture), 'Autonomic nervous system', 'ANS', 'CVD' (cardiovascular disease), '고혈압', '침', '전침', and '자율신경계'. The studies were analyzed according to the year, type of study (domestic or foreign articles, nationality of the first author), acupuncture type for human and animal studies, BP (blood pressure) measurement, and acupuncture intervention. Results: In total, 21 articles were selected. There were 8 randomized controlled trials (RCTs), 3 non-randomized controlled trials (nRCTs), 2 before-after studies, 1 case series, and 7 animal studies. Manual acupuncture (11 articles) was most frequently used, and ST36 (足三里) was most frequently used in human studies. In 18 of 21 articles, acupuncture was reported as effective in lowering systolic blood pressure (SBP) or diastolic blood pressure (DBP) in hypertensive patients. Conclusions: Acupuncture treatment for hypertension is deemed useful. Further studies are necessary for application of acupuncture therapy in clinical practice.
