Gi(氣) transformation theory is the foundation of Traditional Chinese Medicine[TCM]. This theory matured during the period of "Hwangjenaegyeong(黃帝內經)", and later in the history of TCM was a source of significant impact on the development process and direction of general medical theory. The concept of "gi transformation[氣化]" mainly originates from the definition of the three levels which are nature, the relationship between nature and human, and the body's own metabolism, and is used to describe the usage and the resulting changes of 'gi(氣)'. Gi transformation possesses six characteristics which are permanence, universality, representationalism, directional, variability, and orderliness. The research of the concept and characteristics of gi transformation[氣化] in "Hwangjenaegyeong" will help identify the important academic value and practical significance of the formation of the basic theory of TCM as the result of the gi transformation theory, and highlight the unique characteristics of TCM.

Glomus tumors of the lung are rare benign neoplasm, originating from modified smooth muscle cells. The patients are usually presented with no or non-specific symptoms such as cough, dyspnea or hemoptysis. Although surgical treatment is considered as the treatment of choice, the endobronchial therapy can be applied to the patients who are unfit for surgical excision. Herein, we describe two rare cases of glomus tumor originated at large airway (trachea and main bronchus) without respiratory symptoms and review their characteristic radiologic, macroscopic and pathological features.

In this study, we investigated how prescriptions from "Sanghallon(傷寒論)", such as Oryeongsan(五笭散), Banhasasimtang(半夏瀉心湯), Dohaekseunggitang(桃核承氣湯), Jukyeopseokgotang(竹葉石膏湯), were applicated in Onbyeongjobyeon(溫病條辦). When applying prescriptions from "Sanghallon" onto Onbyeong(溫病), Odang had replaced warm, dry herbs with cool herbs which generate body fluid, considering general characteristics of onbyeong that may easily dry up and injure body fluid. In the case of Seuponbyeong(濕溫病), however, warm, dry herbs were also used, as well. Odang did not persist in the general characteristic of onbyeong, but composed prescriptions only based on pathological condition. From this, one can point out his precise thinking of Byeonjeung(辯證), and pragmatic nature of his study.

Objective : To clarify the features of needling method in the Zhenjiu Jiayijing, the needling depth and needling treatment time were sorted out. Method : According to the analysis, we can identify the crucial factors of the needling features. Result : Compared with the needling related content of Huangdi Neijing(黄帝内经), the historical outline of the needling development could be found and the ancient acupuncturing process was reappeared with a historical perspective. This research will provide guidance for the literature research and clinical application. Conclusion : Zhenjiu Jiayijing, also an important and valuable literature, will provide more evidence or clues for depth and treatment time of needling, which will be helpful and meaningful in clinic.

Ameloblastic fibro-odontoma(AFO) is a rare mixed odontogenic tumor. It is composed of connective tissue characteristic of an ameloblastic fibroma and calcified tissue as a complex or compound odontoma. AFO usually presents itself as an asymptomatic swelling of jaw or failure of tooth eruption. The lesion usually occurs in individual less than 30 years old. The differential diagnosis of this tumor includes odontoma, ameloblastoma, and ameloblastic fibroma. This report describes an ameloblastic fibro-odontoma occurring in maxilla of sixteen-year-old female. The lesion was treated by surgical enucleation and curettage without extraction of the involved canine(#23). This patient has shown no sign of recurrence during postoperative 34 months. So we report our case with review of literatures

This paper proposes to examine how herbal medicine studies developed amidst the historical changes, by studying the publications of herbal medicine books. For this reason, centering on the most eminent herbal medicine books of each period, the characteristic of the times shown by their publication and the development of herbal medicine were summarized. Also, traces of herbal medicine books among the eminent classics that were imported into our medicine and made a deep impact, and whether or not a Chosun edition was published were researched and introduced in order to show the influence it had on Korean Medical History.

A 13-year-old male with normal immunity presented with Aspergillus brain abscess manifestating as frontal headache and fever. $T_2$-weight magnetic resonance imaging revealed a hypointense lesion in the right fronto-temporo-parietal lobe 1cm thickness and left midline shifting. The hypointense appearance on $T_2$-weighted images appears to be characteristic of aspergillosis. Right decompressive craniectomy and removal of subdural empyema right. Abscess culture was Aspergillus fumigatus. Antibiotic treatment with Amphotericin B was given for 2 months postoperatively. No recurrence was identified during 5 month follow-up.

A 49-year-old woman presented with headache, vomiting and visual disturbance. Neurological examination revealed bitemporal hemianopsia with poor visual acuity. Magnetic resonance imaging showed a bulky intra-suprasellar mass, which was isointense with brain parenchyma on T1-weighted images, and slightly hyperintense on T2-weighted images. After gadolinium administration, the mass was homogeneously enhanced. The mass was partially removed by the endonasal transsphenoidal approach and then the remnant mass was totally removed by the transcranial approach five months later. We found a yellowish mass which was attached to the diaphragm sellae in operation field. Histopathological examination of the tumor revealed the characteristic features of a schwannoma. We report an unusual case of an intra-suprasellar schwannoma resembling a non-functioning pituitary macroadenoma both clinically and radiologically.

This study is about e-Book program based on human-computer interaction(HCI) system for physically handicapped person. By acquiring background knowledge of HCI, we know that if we use vision-based interface we can replace current computer input devices by extracting any characteristic point and tracing it. We decided betweeneyes as a characteristic point by analyzing facial input image using webcam. But because of three-dimensional structure of glasses, the person who is wearing glasses wasn't suitable for tracing between-eyes. So we changed characteristic point to the bridge of the nose after detecting between-eyes. By using this technique, we could trace rotation of head in real-time regardless of glasses. To test this program's usefulness, we conducted an experiment to analyze the test result on actual application. Consequently, we got 96.5% rate of success for controlling e-Book under proper condition by analyzing the test result of 20 subjects.
