  • Objective : The objective of this study is to observe the effect of anti-inflammatory herbal acupuncture on the metatarsal tendinitis. Methods : After the application of herbal acupuncture, the VAS and Baumgaertner's nine point scale were assessed. If there were any restraints on the ROM, ROM was also assessed alongside the previous scales. Results : 1. The pain was reduced significantly according to the VAS scale. 2. As to the assessment of satisfaction in treatment, by the Baumgaertner's nine point scale, 2 out of 3 cases scored Excellent, and one case scored Good. Conclusions : The anti-inflammatory herbal acupuncture is effective to the metatarsal tendinitis, and can be used more frequently in the clinical practices.

  • The inelastic buckling behaviour of continuously restrained two and three-span continuous beams subjected to concentrated loads and uniformly distributed loads are studied in this paper. The restraint type considered in this paper is fully restrained against translation and elastic twist applied at the top flange. These types of restraints are most likely experienced in industrial structures, for example steel-concrete composite beams and half through girders. The buckling analysis of continuous beam consists of two parts, firstly the moment and shear distribution along the member are determined by employing force method and the information is then used for an out-of-plane buckling analysis. The finite element method is incorporated with so-called simplified and the polynomial pattern of residual stress. Owing to the inelastic response of the steel, both the in-plane and out-of-plane analysis, which is treated as being uncoupled, extend into the nonlinear range. This paper presents the results of inelastic lateral-torsional and lateral-distortional buckling load and finally conclusions are drawn regarding the web distortion.

  • In this paper constant power models for electric trains have been used to analyze the steady states of the AT feeding systems. There are some previous studies utilizing constant impedance models or constant current models. These mentioned models are easy to use, but even so they don't yield exact results because of the innate restraints of the models since linear models cannot represent the characteristic of constant power in inverter-driven trains. It is reasonable that the train be considered as a constant load model when it drives or as a constant source model when it applies regenerative brake. Nonlinear equations which reflect constant power model for train have been developed by considering mutual impedances between wires and AT's turn-ratio of 1:1, then these equations have been solved by N-R iterative method. The proposed method doesn't need any specific assumptions through either the process of developing equations or the process of acquiring solutions, so it can be said to be stricter than other conventional methods.

  • 독일의 독점금지관련 법제는 크게 기업의 불공정 경쟁행위를 규제하기 위하여 1909년에 제정된 부정경쟁방지법(UWG:Gesetz gegenden Unlauteren Wettbewerb, AUC:Act against Unfair Competition)과 제 2차대전 후 금융자본에 의한 기업의 카르텔과 콘체른의 성행으로 독과점의 폐해가 심해지자 독과점 규제의 실효성을 위하여 1957년 제정된 경쟁제한금지법(GWB:Gesetz gegen Wettbewerbs Beschrankungn, ARC: Act against Restraints of Competition)이다. 부정경쟁방지법은 부당한 거래거절이나 부당한 거래방해 행위, 부당한 차별적 취급 및 기만적인 광고 등 기업의 영업활동과 관련한 불공정경쟁행위 규제가 주된 목적으로서 민사절차에 의한 손해배상소송 등에서 활용되고 있으며 경쟁제한금지법과 중복되는 분야(부당한 거래거절 등)에 대하여는 행정벌의 부과를 규정하고 있어 경쟁제한금지법과 상호보완적 관계를 유지하고 있다. 따라서 본고에서는 독일의 경쟁제한금지법의 내용에 대해서만 살펴보기로 한다.

  • Intravenous midazolam has been frequently used for the relief of anxiety in dental treatment. This is likely the result of the sedative and anterograde amnestic properties of midazolam that are mediated through $\gamma$-Aminobutyric acid agonism. Unfortunately, Paradoxical reactions to midazolam include agitation, talkativeness, confusion, disinhibition, aggression,violent behavior, act of self-injury and need for restraints. These occur in less than 1% of all patients receiving midazolam, may occur at variable times after administration and are difficult to predict and diagnose. Two women with severe anxiety for dental treatment experienced paradoxical reactions associated with the use of intravenous midazolam. We are reviewed the management and prevention of paradoxical reactions and its different etiology.

  • The objectives of this paper are to estimate differential column Shortening and to determine appropreate compensation amount in 52 story Amatapura Apartment in Indonesia. for this, a computer program based on PCA and CEB-FIP code is developed. The results show that Elastic and Creep strain are the main factors of column shortening and the maximum differential shortening is appeared near the middle of the building height. The results between field survey and estimation have some difference, the most influential factor of the difference can be lateral restraints provided by horizontal members, which cannot be handled in this developed program. Hence introducing the modification factors from various field survey, this program can be used properly in design and construction procedures.

  • The influences of the large amplitude free vibrations of simply supported Timoshenko beams with ends restrained to remain a fixed distance apart and with no axial restraints, which cause a longitudinal elastic force and a longitudinal inertia force, respectively, are investigated. The equations of motion derived by an appropriate linearizarion of the nonlinear strain- displacement relation have nonlinear terms arising from large curvature, longitudinal elastic force and longitudinal inertia force. The fourth order nonlinear partial differential equations for the deflection, can be reduced to the nonlinear ordinary differential equations by means of Galerkin procedure and a modal expansion. The general response and frequensy-amplitude relations are derived by the perturbation method of strained parameters. Comparison with previously published results is made.

  • Hofstede cultural value model is one of the most influential model for cross-cultural studies to measure national difference. In this study, we examine that Hofstede Cultural Dimensions can be measured by World Value Surveys. Selected WVS questions for 31 measurable countries after Exploratory Factor Analysis(EFA) and Confirmatory Factor Analysis(CFA), approved valid through empirical analysis. It is applicable that Individualism values(IND) has related to 2 questionnaires including life satisfaction, Power Distance values(PDI) to 2 questionnaires about political action(Signing a petition and Joining in boycotts), Masculinity values(MAS) to 2 sexual-role questionnaires like "University is more important for a boy than for a girl", Uncertainty Avoidance values (UAI) to 3 questionnaires about confidence(Parliament, The Political parties and Justice System), Long-Term Oriented values(LTO) to 4 questionnaires including "How proud of nationality" and Indulgence versus Restraints values (IVR)to 2 questionnaires including Feeling of Happiness.

  • This paper deals with the free vibrations of horizontally curved beams on an elastic foundation. Taking into account the effects of rotatory inertia and shear deformation, the differential equations governing free vibrations of noncircular curved beams resting on Pasternak-type foundations are derived and solved numerically. The lowest three natural frequencies for parabolic curved beams with hinged-hinged and clamped-clamped end restraints are calculated. Numerical results are presented to show the effects on the natural frequencies of the non-dimensional system parameters: the horizontal rise to span length ratio, the Winkler foundation parameter, the shear foundation parameter, and the width ratio of contact area between the beam and foundation.

  • This paper documents an experimental study of dynamic response of reinforced concrete beams following instantaneous removal of a bearing column. Four half-scale specimens representing two-span beam bridging across the removed column were tested. The test boundary conditions simulated rotational and longitudinal restraints imposed on a frame beam by the neighboring structural components. The gravity loads were simulated by attaching mass blocks on the beams at three locations. Dynamic loading effects due to sudden removal of a column were simulated by quickly releasing the supporting force at the middle of the specimens. The experimental study investigated the load-carrying capacity of beams restrained longitudinally at the boundaries and dynamic impact on forces. The tests confirmed the extra flexural strength provided by compressive arch action under dynamic loading. The tests also indicated that the dynamic amplification effects on forces were much lower than that assumed in the current design guideline for progressive collapse.
