  • With the advent of high-resolution high-sensitivity observations, spiral patterns have been revealed around several asymptotic giant branch (AGB) stars. Such patterns can provide possible evidence for the existence of central binary stars embedded in outflowing circumstellar envelopes. It is, however, not generally recognized that the binary induced pattern, vertically extended from the orbital plane, exhibits a ring-like pattern with an inclined viewing angle. I will first review the binary-induced spiral-shell patterns on the AGB circumstellar envelopes with the effect of inclination angle with respect to the orbital plane, of which large inclination cases reveal incomplete ring-like patterns. I will describe a method of extracting such spiral-shell from the gas kinematics of an incomplete ring-like pattern to place constraints on the characteristics of the (unknown) central binary stars. This first success may open the possibility of connecting the ring-like patterns commonly found in the AGB circumstellar envelopes and in the outer parts of (pre-)planetary nebulae and pointing to the conceivable presence of central binary systems, which may give a clue for the onset of asymmetrical planetary nebulae.

  • Intermediaries are presenting not only transactional information that orchestrates electronic transaction, but also market related information and knowledge useful for sellers' understanding of the market status. However, we do not have strong evidence that the market related information and knowledge is properly utilized by sellers and that it has an actual influence on sellers' performance. According to the research result, absorptive capacity and the pattern of information system utilization is statistically significant to sellers' performance mediated by operational efficiency and market knowledge creation. Especially, explorative utilization of information system and realized absorptive capacity has a stronger influence on sellers' performance mediated by market knowledge creation. With this research result, this study maintains that sellers are required to absorb and utilize market related information and knowledge more actively through explorative utilization of information system to achieve better performance in the e-marketplace. On the other hand, intermediaries are recommended to provide abundant and valuable market related information and knowledge for the sellers to build up better e-marketplaces.

  • Microscopic polyangiitis (MPA) is an antineutrophil cytoplasmic antibody (ANCA)-associated necrotizing vasculitis, which mainly affects small vessels in various organs, especially the lungs. The two key pulmonary manifestations, interstitial lung disease (ILD) and diffuse alveolar hemorrhage (DAH), increase the morbidity and death rate of patients with MPA. ILD is more common in MPA than in other ANCA-associated vasculitis subsets and is primarily associated with myeloperoxidase-ANCA. Unlike alveolar hemorrhage due to pulmonary capillaritis, ILD can initially manifest as isolated pulmonary fibrosis. Of note, its most frequent radiographic pattern is the usual interstitial pneumonia pattern, similar to the characteristic pattern seen in idiopathic pulmonary fibrosis. In this review we present the pathogenesis, clinical manifestations, and radiographic and histopathologic features of ILD and DAH in MPA. We also briefly summarize the outcome and therapeutic options for the two conditions.

  • Hwa-byung is a form of psychogenic illness among people in Korea and is listed as a culture-bound syndrome of Korea in the DSM-IV. Despite increased clinical researches for Hwa-byung in the oriental medicine of Korea, there has been no agreement of pattern identification for Hwa-byung. The purpose of this study is to develop a standard instrument of pattern identification for Hwa-byung which will be applied to clinical research. The items and structure of the instrument were based on review of published literature. The advisor committee on this study was organized by 15 neuropsychiatry professors of 11 oriental medical colleges nationwide. The experts attended 2 consultation meetings and discussed developing the instrument. and we also took professional advices by e-mail. The results were as follows; First, we divided the symptoms and signs of Hwa-byung into five pattern identification - stagnation of liver Qi, flare-up of the liver fire, disharmony between heart and kidney, deficiency of both Qi and blood, malfunction of gallbladder due to phlegm stagnation. Second, we got the mean weights to each symptom of five pattern identification which had been scored on a 5-point scale - ranging from 0 to 4 by the 15 experts. Third, we made out the Korean instrument of the pattern identification for Hwa-byung. It was composed of 34 questions and decided on question-and-answer form. Though there are some limits in this study, the instrument of pattern identification for Hwa-byung is meaningful and expected to be applied to the subsequent research. And also, we hope to improve the instrument and make up for this study through various research and discussion.

  • Although there have been studies investigating the clinical effects of warm needling (WN) for specific diseases, a comprehensive review of WN is needed. Four Korean internet databases were used in the review of WN treatment performed in Korea. The search terms used to retrieve articles were "warm needling (in Korean; 온침)," "warm acupuncture," and "warm needle." A total of 29 articles were reviewed. The following aspects of WN were investigated: language and terminology, study design, use of Standards for Reporting Interventions in Clinical Trials of Acupuncture, research ethics, moxibustion types, number of moxa used, moxa combustion time, needle retention time, treatment time and frequency, acupoints, meridians, acupuncture size and depth, disease classification, pattern identification, outcome measures, and adverse effect. More sophisticated and precise studies on WN are required.

  • Background : Static blood is a kind of etiological factor including stagnated blood and blood overflowed out of the vessels. It is one of the causes of stroke in oriental medicine. Objectives : The purpose of this study was to evaluate the static blood pattern and its indicators in stroke pattern diagnosis. Methods : For the standardization of pattern diagnosis in stroke, we set 5 patterns (Fire-heat, Dampness-phlegm, Static blood, Qi deficiency, Yin deficiency) and developed 61 indicators. Patients with a first-ever stroke, within 1 month after the onset of stroke. Two physicians checked the indicators independently. They then performed pattern diagnosis and rechecked the indicators which were referred to pattern diagnosis. If pattern identifications were diagnosed the same, it would confirm pattern identification. We examined the frequency of all indicators and referred indicators in static blood pattern patients. Results : In 859 patients, static blood pattern was shared by 24(2.8%). The indicators which affect static blood pattern were mainly rough pulse and bluish purple tongue, other indicators were not major effectors. Conclusion : This result shows that it is inconsistent to set up static blood pattern as a major pattern in stroke. Nevertheless, static blood is still a valuable concept in the clinical field. Other study methods will be required to establish the pattern diagnostic indicators for static blood pattern.
