Objectives : Historical study on application of Kyungohkgo, one of the most popular tonic medicine, and suggestion of modernistic method through it Methods : Investigated effect and its range of Kyungohkgo in original texts of Korean medicine, and researched studies on medical action and treatment effect of Kyungohkgo nowaday. Results : Kyungohkgo has "replenish essence and marrow(補精益髓)" as a major effect, and various original text suggested that Kyungohkgo can be used as antioxidant tonic medicine, treatment of respiratory disease like tuberculosis and medicine for bone disease controling hormone. Several research about these subjects has been progressed recently. However, the most of these researches is not an in-depth study about virtues in original texts, but deduced from effects of Kyungohkgo, and there are some studies experimented with Kyungohkgo that has not followed its own formula. Conclusions : It is required to discuss new application based on understanding effect and is range of Kyungohkgo. It could be thought that using for skin disease based on t theory of "lung presides skin and hair", chronic pulmonary disease based on treatment of cough(咳嗽), and disease of uterine and bone based on "replenish essence and marrow(補精益髓)".

Hip joint is one of the most deeply located joint in human body. Moreover, most clinical symptoms of various hip diseases are vague and confusing. In these reasons, the imaging modalities of hip have been extensively studied and developed. From a plain radiograph to more complex MR arthrography, various techniques are now available. In this brief review, the long and short of imaging modalities and clinical examples of common hip diseases will be introduced. The most important significance of diagnostic imaging is its clinical relevance. It is because when we know the characteristics of the imaging modalities and the disease itself, the optimal approach to a patient can be achieved, but when we do not know, the expensive images can only be a meaningless picture.

Bar fractions depend on the properties of host galaxies. However, the observational studies did not provide consistent tendency. We investigated the bar fractions and their dependence on properties of host galaxies using three bar classifications: visual inspection, ellipse fitting method and Fourier analysis from a volume-limited sample of 1,698 disk galaxies brighter than Mr=-15.2 within z = 0.01 from the Sloan Digital Sky Survey (SDSS) Data Release 7 (DR7). We found two causes to make the discrepancy in previous studies. One is caused by the difficulty in automatically identifying bars for bulge-dominated galaxies. In particular, ellipse fitting methods could miss early-type barred galaxies when a large bulge weakens the transition between a bar and disk. The other is caused by the difference in the correlation between the bar types and host morphology for strong bars and weak bars. Strong bars are preponderant in early-type spirals which are red, bulge-dominated and highly concentrated, whereas weak bars are frequent in late-type spirals which are blue, disk-dominate and less-concentrated. Therefore, how much weak bars they contain affects the trend of bar fraction on host galaxy properties. We also discuss the effect of host properties on the formation, evolution, and destruction of bars.

Referring to John Irving's 2001 published fiction The Fourth Hand, the publisher commented, "It seems, at first, to be a comedy, perhaps a satire, almost certainly a sexual farce. Yet, in the end, it is as realistic and emotionally moving as any of Mr. Irving's previous novels." In his early six novels, John Irving shows the world suffused with grief and deception. But his novels finally turn out also as a comic and robust novel. The writer's success in achieving this thick description of the contradictory modern world is largely due to his development of the idea of the flawed hero. Despite loss, sadness and abandonment, Irving's heroes maintain classical heroic traits such as intelligence, tenderness, protectiveness, strength, bravery, sense of humor, independence, attractiveness. In this article, I tried to emphasize these graces potent in Irving's heroes as the most attractive and influential device for the writer's consistent popularity among the general public. The cinematization of his four fictions attest to audience's sympathy toward rewarding vulnerability and truthful exaggeration in the depiction of Irving's heroes. By taking full responsibility for their own fate despite having the flaws, Irving's protagonists still appeal to many readers as heroes resilient in a modern chaotic world without losing their graces.

Objective: The aim of this study was to analyze domestic and foreign studies using virtual reality or metaverse for exercise rehabilitation in order to help the disabled or elderly patients with exercise rehabilitation, and suggest a method for using metaverse for exercise rehabilitation. Method: In this study, after analyzing and discussing various information related to the metaverse and exercise rehabilitation through electronic search of recently published papers, academic journals, books, and internet websites, the exercise rehabilitation plan using the metaverse was proposed. Results: In the case of domestic research, the diversity of virtual reality application technology for the rehabilitation of disabled and elderly patients was not secured, but recently, virtual reality or metaverse-related technologies were developed and specialized in a form suitable for exercise rehabilitation. In the case of overseas studies, it was analyzed that exercise rehabilitation using virtual reality and metaverse games for the rehabilitation of disabled and elderly patients can help improve brain, physical ability, and anti-aging by activating the body and mind. Conclusion: Smart metaverse health care is actively introduced to exercise rehabilitation, metaverse telemedicine business is applied to exercise rehabilitation programs, and digital twin games and exercise rehabilitation programs developed by metaverse related companies take into account the characteristics of disabled and elderly patients. If customized smart metaverse healthcare is used for exercise rehabilitation, it is analyzed that it can lead this field.

In this paper we attempt to read a film by Haejoon LEE entitled 'Castaway on the moon' from the Bauman's modernity perspective that draws our attention to uncomfortable problems relative to wastes and wasted lifes in the global consumer society we all live in. The so-called consumer society is a post-modern society designed according to the following two criteria: on the one hand, beauty and ugliness and on the other hand, competence and incompetence. Classified as ugly as well as incompetent in this society, the two heros in this film are condemned to live their lifes isolated. Miss Kim is confined to her small room while Mr. Kim is exiled to an uninhabited island called 'Bamsum' in the Han River. In these spaces, neither inside nor outside, they perform what we would like to call 'surplus act', using wastes at their disposal. In this paper we ask ourselves whether or not this act is able to challenge the two criteria and the solidarity of the two wasted lifes can bring about change in the consumer oriented society. As well as Bauman, Agamben will help us approach this question from a theoretical point of view.

A 16-year-old female was admitted to Wonkwang dental hospital with a chief complaint of painful ulceration on right buccal mucosa around mandibular 3rd molar area. Computed tomography and magnetic resonance imaging showed relative large soft tissue mass on the infratemporal fossa and masseter muscle region. By the feature of T1-weighted and T2-weighted of MR imaging, we suspected this mass as a kind of myogenic sarcoma. Histopathological and immunohistochemical studies established a definitive diagnosis of embryonal rhabdomyosarcoma. A review of the literature was also presented.

An outrigger damper system has been proposed to reduce dynamic responses of tall buildings. In previous studies, an outrigger damper system was optimally designed to decrease a wind-induced or earthquake-induced dynamic response. When an outrigger damper system is optimally designed for wind excitation, its control performance for seismic excitation deteriorates. Therefore, a smart outrigger damper system is proposed in this study to make a control system that can simultaneously reduce both wind and seismic responses. A smart outrigger system is made up of MR (Magnetorheological) dampers. A fuzzy logic control algorithm (FLC) was used to generate command voltages sent for smart outrigger damper system and the FLC was optimized by genetic algorithm. This study shows that the smart outrigger system can provide good control performance for reduction of both wind and earthquake responses compared to the general outrigger system.

Tietze's syndrome is an inflammatory condition associated with painful swelling of the costochondral, costosternal, and sternoclavicular joints. Tietze's syndrome has been mostly attributed to microtrauma until now; however, this etiology is currently disputed. The diagnosis is based on clinical findings, although a few studies suggest the advantages of imaging. We report a case of Tietze's syndrome with a review of radiological findings, especially magnetic resonance imaging (MRI) with dynamic contrast enhancement.

MRI imaging provides many benefits such as noninvasive, 3-dimensional imaging capabilities. But it has relatively serious drawback that is the long data collection time, compared with other imaging modality. Many studies have been performed for fast MR imaging. But EPI and SEPI (4-6) are required to expensive hardware. In this paper, we introduce to Burst imaging technique. It can reduce imaging time by use of a mulitple RF excitation technique. Further it is easily implemented to the normal MRI system. But a pixel profile in the conventional burst sequence is so poor that excited area by burst sequence is a small portion of a pixel. This causes poor signal to noise ratio in burst image. therefore frequency sweeping of RF pulse for burst imaging sequence is proposed to improve pixel profile. A burst pulse train is shaped by liner or nonlinear frequency sweeping function so that all the spins within a pixel are excited, thereby improving the signal to noise ratio. It also shows that the pixel profiles are dependent on how frequency sweep is made. Computer simulations with Bloch equation and experimental results obtained using a 1.0 T NMR imaging system are presented.
