  • This paper deals with stand-alone Photovoltaic system(SPVS) with charge and discharge controller. Main power source of SPVS are generally solar cell and battery. therefore SPVS can be classified into variable types in accordance with connection type between battery and solar cell. Mainly used one of them is direct connection type which has advantages such as simple structure and simple controller. However most big drawback of this system is energy loss by voltage disharmony between solar cell and battery. Therefore SPVS with charge and discharge controller which can operate solar cell at maximum power point is designed and analyzed by simulation in this paper.

  • Through researching 鄕藥救急方, the oldest medical text published in Korea in existence known to date, a study from a Traditional Korean Medicine perspective was conducted. This study aims to observe the treatment of oral, glottal, labial, and dental diseases starting from 統一新羅時代 to the Koryo dynasty from a historical perspective and also find out what clinical significance it withholds. "鄕藥救急方" proposes methods of nurturing the teeth and in doing so displays the tendency of Traditional Korean Medicine of putting much weight on preventing diseases and nurturing the body. "鄕藥救急方" considers the oral, glottal, labial, and dental diseases as not only fundamental problems in itself but also treats them from a perspective that they are results of disharmony among the five viscera and the six bowels. The treatment methods mentioned in "鄕藥救急方" are directly cited in "鄕藥集成方" of early Chosun dynasty. In "東醫寶鑑" of mid-Chosun dynasty, however, changes and modificatios are made to the prescriptions.

  • Chronic recurrent TMJ dislocation results in difficulty of mastication, speaking, and swallowing due to the limitation of the mandibular movement. Etiologic factors are considered as the looseness of the capsule and ligaments, the decrease of the articular eminence, condylar morphologic change, muscular disharmony near by TMJ, and the decrease of the vertical length of the mandibular ramus. Treatment approach has been suggested that surgical methods are selected for the correction of the etiologic factors when conservative treatments are not effective. Many surgical methods have been reported such as eminectomy, eminence augmentation, condylotomy, and zygomatic arch down fracture technique. We performed the eminence augmentation through interpositional bone graft in chronic recurrent TMJ dislocation. This method leads to favorable postoperative result without recurrence and complication, so we report the case with related references.

  • Review is made on the sweat in 'Donguibogam' from the view point of Hyungsang medicine. The conclusions are as follows: Clinically sweet is an important indicator for the condition and constitution of the patients. Sweat should be taken into consideration in diagnosis and treatment. Sweat is one of the symptoms that appears when there is a disharmony among Jung(精), Ki(氣) and Shin(神). The cause and phase of sweat varies with every patient. Dam type persons (膽體) are inclined to have night sweat, while Bangkwang type persons(膀胱體) are apt to have day sweat.

  • A well-maintained landscape can increase the competitiveness of a city. Gyeongju which is the famous ancient capital of Korea, has numerous historical resources. However, the disharmony between the historical landscape and the surrounding landscape weakens the competitiveness of the city. At present, most landscape analysis methods mainly focus on plans, photos, and animation, which have certain limitations in the expression of landscape spatial scale and materials. This study aimed to use the virtual walkthrough method to take the Wolseong District of Gyeongju historical areas as the object in order to evaluate the landscape visually. Compared with planar landscape analysis methods, such as photos and videos, the virtual walkthrough method is more immersive and intuitive to experience the spatial scale. The study results revealed images, visual characteristics, and visual influence factors of the landscape, which provide essential data for the construction and improvement of landscapes in similar historical areas in the future.

  • This review article attempts to describe several pathological conditions that can arise from the shortening of the Achilles tendon. The tension and tightening of the gastrocnemius-soleus-Achilles tendon complex (GSAC) can cause disharmony in the movement of the entire foot as well as the ankle joint when subjected to weight-bearing or walking. In addition, since these phenomena are observed in various lesions of the ankle joint, the dynamic shortening caused by the tension of GSAC may not be the primary cause of various ankle joint lesions, but is still considered to be a significant contributing factor.

  • 교합의 부조화가 있고 중심위와 최대 교두간 접촉위의 불일치가 과도하며 이와 관련된 병적인 징후가 관찰되는 경우, 반복 재현이 가능한 안정된 교합을 얻고 상실된 저작기능을 회복하기 위해 교합치료를 고려해야 한다. 면밀한 진단을 통하여 중심위를 기준으로 한 악간 및 교합관계를 분석하여 그 부조화의 정도에 따라 교합조정이나 보철수복, 교정치료, 악교정 수술 등을 시행할 수 있다. 본 증례의 환자는 수 년 전부터 발생한 교합 불안정 및 저작기능 상실을 주소로 본원에 내원하였으며 내원 당시 최대 교두간 접촉위에서 상악 우측 제2대구치만 접촉이 이루어지는 심한 교합부조화를 보였다. 중심위를 기준으로 한 교합분석 결과, 교합조정이나 보철수복을 통한 치료만으로는 문제를 해결하기 힘든 상,하악간 골격성 2급의 심도가 매우 깊었다. 따라서 임시의치수복을 통한 중심위를 확보하고 심한 골격성 2급을 해결하기 위한 술 전,후 교정치료를 동반한 양측 하악골 상행지 시상분할 골절단술(bilateral sagittal split ramus osteotomy, BSSRO)을 시행하였다. 이후, 전악에 걸친 세밀한 교합조정을 시행하여 교합을 더욱 안정화시켰으며, 무치악 부위는 임플란트를 식립하고 임시수복 하였다. 경과관찰 동안, 주기적인 교합평가 및 추가적인 교합조정을 통하여 안정적인 중심위와 조화로운 전방 및 측방유도를 얻었다. 이에 최종 보철수복을 완료하여 환자의 저작기능을 회복하였기에 이를 보고하는 바이다.

  • The objective of tills study is to identify the difference of somatic characteristics between Hwa-Byung and Major Depression by comparing the pattern identification of Hwa-Byung group and Hwa-Byung with Major Depression group(double diagnosis) Method: According to Hwa-Byung Diagnostic Interview Schedule(HBDIS) and SCID, 17 patients as diagnosed Hwa-Byung and 20 patients as diagnosed Hwa-Byung with Major Depression group(double diagnosis) were recruited. and by depression scale like Hamilton Rating Scale for Depression(HRDS) & Montgomery-Asberg Depression Rating Scale(MADRS), we excluded patients complaining moderate & severe depression among Hwa-Byung group and excluded patients showing mild depression among Hwa-Byung with Major Depression group. After this evaluation, we analysed and compared the pattern identification of both groups by OMS-prime. Result: 1. There were no significant differences of demographic data between both groups. 2. In the result of 'analysis on pattern identification' for all participant used by OMS-prime, most frequent pattern was deficiency of Yin and Yang of the heart(49%). 3. In the result of 'analysis on most correlated pattern identification' used by OMS-prime, for Hwa-Byung group was deficiency of Yin and Yang of the heart(45%) and the next were disharmony of the liver and spleen (20%), generation of phlegm due to stagnation of Gallbladder(15%) deficiency of Qi and Yin of the heart(l0%), And for Hwa-Byung with Major Depression group(double diagnosis) was deficiency of Yin and Yang of the heart(53%), the next were generation of phlegm due to stagnation of Gallbladder(18%), and deficiency of Qi and blood of the heart(l2%), 4. In the result of 'analysis on significant pattern identification' used by OMS-prime, for Hwa-Byung group was deficiency of Yin and Yang of the heart(20%) and the next were disharmony of the liver and spleen(15%), generation of phiegm due to stagnation of Gallbladder(15%), deficiency of Qi and Yin of the heart(14%), And for Hwa-Byung plus Major Depression group(double diagnosis) was deficiency of Yin and Yang of the heart(18%), the next were deficiency of Qi and Yin of the heart(18%), deficiency of Qi and blood of the heart(l0%), generation of phiegm due to stagnation of Gallbladder(18%), Conclusion: Hwabyung is syndrome that have many different symptoms, but there is no difference between Hwa-Byung group and Hwa-Byung with Major Depression group(double diagnosis) on the side of symptoms. Therefore, Hwabyung could be a new model for research on depression in Korean.
