Following conclusions are drawn from study about Yukmigiwhangwon through referring to literatures and reviewing in the point of Hyungsang medicine. Yukmigiwhangwon was prescribed by Jeon Eul in order to cure five kinds of flaccidity of infants, but after since then it has been basically applied to symptoms which was caused by deficiency of the kidney not only infants but also adult. The deficiency of kidney is the lack of vital essence and body fluid stored in kidney, it happens because infants are born in the conditions of lack of receiving in the womb. And it happens because adults infringe the rules of life, especially the sexual life. Main symptoms of the poverty of renal functions are emptiness of the brain marrow, dizziness, forgetfulness, tinnitus, deafness, vertigo and dim eyesight, insomnia, the low back and knees aching and limping, heat on the legs, tibia aching, nocturnal emission, dry mouth, reddened tongue and little coating or non coating of the 'tongue, weak blood meridians. the treating method is nourishing Eum and supplementing kidney. In Dongeuibogam Yukmigiwhangwon is mentioned in the parts of vital essence, blood, voice, kidney, urine, eye, ear, the low back, hair, fire, exhaustion syndrome, cough, polydipsia, infant, etc. The shapes which Yukmigiwhangwon is applied to are the Dam Body Doing deficiency of Eum due to excess of Yang, man, infant, Jung type, Fish group, reverse triangular shape, big headed man, big eared man, big mouthed man, man having prominent cheekbones, man having long waist, man having big hips, man with thick hair or white hair, man with bald on the head, etc. In color it is applied to darkish complexion, flushed tip of the nose, or flushed cheek bones. Through inquiring into the clinical cases on the points of Hyungsang medicine Yukmigiwhangwon is efficacious cure to lumbago, symptoms of tendons and bones, symptoms of eyes and ears, symptoms of respiratory organs, dermatopathia, headache, polydipsia, urinary disorders, etc.

The inflammatory response during cutaneous leishmaniasis (CL) involves immune and non-immune cell cooperation to contain and eliminate Leishmania parasites. The orchestration of these responses is coordinated primarily by CD4⁺ T cells; however, the disease outcome depends on the Th cell predominant phenotype. Although Th1 and Th2 phenotypes are the most addressed as steers for the resolution or perpetuation of the disease, Th17 cell activities, especially IL-17 release, are recognized to be vital during CL development. Th17 cells perform vital functions during both acute and chronic phases of CL. Overall, Th17 cells induce the migration of phagocytes (neutrophils, macrophages) to the infection site and CD8⁺ T cells and NK cell activation. They also provoke granzyme and perforin secretion from CD8⁺ T cells, macrophage differentiation towards an M2 phenotype, and expansion of B and Treg cells. Likewise, immune cells from the inflammatory infiltrate have modulatory activities over Th17 cells involving their differentiation from naive CD4⁺ T cells and further expansion by generating a microenvironment rich in optimal cytokines such as IL-1β, TGF-β, IL-6, and IL-21. Th17 cell activities and synergies are crucial for the resistance of the infection during the early and acute stages; however, if unchecked, Th17 cells might lead to a chronic stage. This review discusses the synergies between Th17 cells and the inflammatory infiltrate and how these interactions might destine the course of CL.

배경: 외상에 의한 대량출혈은 외상 환자의 주요 사망 원인 중 하나이며, 이 경우 초기에 다량의혈액제제를 적절한 비율로 신속하게 공급하는 것이 외상성 출혈로 인한 사망률을 감소시킨다는 점에서 매우 중요하다. 본 연구에서는 외상 환자에 대한 대량수혈을 보다 안전하고 신속하게 수행하기 위해 마련한 대량수혈 프로토콜(MTP)을 도입한 이후, MTP 적용군과 비적용군의 특성을 비교 분석하여 MTP를 적용할 환자를 예측하는데 도움을 줄 수 있는 임상적 지표가 있는지, MTP를 적용할 경우 보다 신속한 수혈이 가능한지를 확인하였다. 방법: 2018년 2월부터 8월까지 7개월간 단일 3차의료기관의 외상응급실을 통해 입원한 환자들 중 대량수혈을 받은 환자들의 전자의무기록 및 검사결과를 후향적으로 분석하였다. 대량수혈 환자는 초기 24시간 이내에 적혈구제제 10단위 이상을 수혈받은 16세 이상의 환자로 정의하였으며, 이들 중 MTP를 적용받은 군(MTP군)과 비적용군(non-MTP군)을 구분하여 수상 종류 및 메커니즘, 초기 활력징후, 혈액검사결과, 외상 중증도 평가 점수, 수혈된 혈액제제의 비율과 양, 혈액제제가 처방된 시점부터 출고되기까지 소요된 시간을 비교 분석하였다. 결과: 2018년 2월부터 8월까지 7개월간 대량수혈을 받은 53명의 외상환자들 중 MTP군은 31명, non-MTP군은 22명으로 확인되었으며, 수축기혈압 및 이완기혈압을 제외한 초기활력징후 및 초기 혈액검사결과는 두 군간 유의한 차이가 없었다. 두 군의 혈액제제 사용량 및 비율 또한 큰 차이가 없었으나, 혈액제제 출고 소요시간의 경우 non-MTP군보다 MTP군에서 더 짧은 것이 확인되었다. 결론: MTP군과 non-MTP군의 초기활력징후 및 검사결과 등 임상적 특성은 큰 차이를 보이지 않았으나, MTP군에서 혈액제제가 출고되기까지 소요되는 시간이 더 짧아 보다 신속하게 수혈을 시작할 수 있었다.

Successful treatment of a badly broken down tooth with pulpal disease depends not only on good endodontic therapy, but also on good prosthetic reconstruction of the tooth after endodontic therapy is completed. The ideal treatment of endodontically treated teeth has been widely and controversially discussed. Endocrown is a restorative option for endodontically treated teeth. Endocrown design incorporates the core and short post into the crown as a single restoration. The preparation of endocrown consists of a circular equigingival butt-joint margin and central retention cavity of the entire pulp chamber instead of employing intraradicular posts. This design significantly increases the surface area of the preparation available for cementation. It is particularly useful in young patient teeth for long-term provisional restoration and in teeth with short clinical crowns. This technique represents a promising and conservative method for the treatment of endodontically treated teeth that require long-term protection and stability. Endocrown can be considered as a feasible alternative to full crowns or composite overlays for the restoration of non vital teeth.

Analyzing autocorrelated data set is still an open problem. Developing on easy and efficient method for severe positive correlated data set, which is common in simulation output, is vital for the simulation society. Bootstrap is on easy and powerful tool for constructing non-parametric inferential procedures in modern statistical data analysis. Conventional bootstrap algorithm requires iid assumption in the original data set. Proper choice of resampling units for generating replicates has much to do with the structure of the original data set, iid data or autocorrelated. In this paper, a new bootstrap resampling scheme is proposed to analyze the autocorrelated data set : the Threshold Bootstrap. A thorough literature search of bootstrap method focusing on the case of autocorrelated data set is also provided. Theoretical foundations of Threshold Bootstrap is studied and compared with other leading bootstrap sampling techniques for autocorrelated data sets. The performance of TB is reported using M/M/1 queueing model, else the comparison of other resampling techniques of ARMA data set is also reported.

In this study, the dynamic behaviour of a rotating Timoshenko beam when under the actions of a variable magnitude load moving at non-uniform speed is carried out. The effect of cross-sectional dimension and damping on the flexural motions of the elastic beam was neglected. The coupled second order partial differential equations incorporating the effects of rotary and gyroscopic moment describing the motions of the beam was scrutinized in order to obtain the expression for the dynamic deflection and rotation of the vibrating system using an elegant technique called Galerkin's Method. Analyses of the solutions obtained were carried out and various results were displayed in plotted curve. It was found that the response amplitude of the simply supported beam increases with an increase in the value of the foundation reaction modulus. Effects of other vital structural parameters were also established.

Acute idiopathic scrotal edema (AISE) is a self-limiting condition that is characterized by acute scrotal swelling and erythema. AISE is a very rare cause of acute scrotum, especially in neonates. We report a case of AISE in a 26-day-old infant who was admitted to the outpatient clinic with swelling and erythema of the penis and scrotum for a week. His vital signs were stable, and laboratory findings were non-specific. A diagnosis of AISE was made using scrotal ultrasonography with color Doppler. His symptoms resolved within four days after the onset of supportive treatment, and he was discharged from the hospital. In neonates with an acute scrotum, AISE should be considered to prevent unnecessary surgical exploration.

Asbestos is being replaced throughout the world among friction materials because of its carcinogenic nature. This has raised an important issue of heat dissipation in the non-asbestos brake pad materials being developed for automobiles etc. It has been found that two of the components i.e. carbon fibres as reinforcement and graphite powder as friction modifier, in the brake pad material, can playa vital role in this direction. The study reports the influence of these modifications on the thermal properties like coefficient of thermal expansion (CTE) and thermal conductivity along with the mechanical properties of nonasbestos brake pad composite samples developed in the laboratory.

Information, or the lack of information, is the central concern of many people. And it is now an economic resource and must be paid. An ever increasing gap will grow between information 'have' and 'have not'. The new communications market place is a social phenomenon, and a vital key to examining changing patterns of social and cultural inequality. There are two main arenas of action in this ongoing conflict. Inside the library system itself, a combination of forces is weakening the historic principle of free, socially underwritten access. Outside, great efforts have been exerted in recent years, by private interests, to capture the information stockpiles built up from tax-su n.0, pported outlays on research and development and general governmental activities that produce data. The for-profit a n.0, pplication of the new information technologies threatens the survival of the free access principles. And the commercialization of information is proceeding almost uninterruptedly. It has been extended into areas that historically have been regarded as non-profit-making and endowed with a deep public interest. This study discussed some general issues and what we should do.
