Background: With the advances of video technology, thoracoscopic surgery has been applied to various areas of the thoracic surgical fields including major surgeries. Now a days,-thoracoscopic surgery is Performed as a procedure of choice for primary spontaneous pneumothorax. But the operative indication for the primary spontaneous pneumothorax has not been changed since the last few decades, although the procedure of choice was changed from open thoracotomy to thoracoscopy. Therefore, we thought new treatment strategy will be necessary for the management of primary spontaneous pneumothorax. Material and Method: Between January 1998 and December 1999, 149 primary spontaneous pneumothorax patients were admitted to the Kyungpook National University Hospital. Result: Of these patients, 177 were first attack pneumothoraces and the number of total attacks were 250. Conclusion: Analyzing the amount of pneumothorax, methods of treatment, number of recurrences, recurrence rate and hospital stay, we propose a critical pathway for establishing new treatment strategy for the management of primary spontaneous pneumothorax.

For the purpose of experimental and clinical studies on the 14 channels and collaterals, we performed an inquiry on the anatomical mapping of neronal, circulatory and muscular networks in the human body which possibly correspond to the major pathway of Du channel and Ren channel known to be critical for overall controlling and mediating 12 regular channel connections. The theoretical background of this analysis was based on the oriental medicinal treatises which described acu-points and related anatomical informations. We suggest that rearrangement methodology for the 12 regular channels as described here may be applied to other 12 regular channels and to develop the new concept on the elucidation of the medical efficacy based on precise anatomical localization of channels and collaterals as well as the meridian points. It is proposed that interdisciplinary studies between oriental and western medicine are critical for more efficient achievement.

Quantitative microbial risk assessment (QMRA) analyzes potential hazard of microorganisms on public health and offers structured approach to assess risks associated with microorganisms in foods. This paper addresses specific risk management questions associated with Staphylococcus aureus in kimbab and improvement and dissemination of QMRA methodology, QMRA model was developed by constructing four nodes from retail to table pathway. Predictive microbial growth model and survey data were combined with probabilistic modeling to simulate levels of S. aureus in kimbab at time of consumption, Due to lack of dose-response models, final level of S. aureus in kimbeb was used as proxy for potential hazard level, based on which possibility of contamination over this level and consumption level of S. aureus through kimbab were estimated as 30.7% and 3.67 log cfu/g, respectively. Regression sensitivity results showed time-temperature during storage at selling was the most significant factor. These results suggested temperature control under $10^{\circ}C$ was critical control point for kimbab production to prevent growth of S. aureus and showed QMRA was useful for evaluation of factors influencing potential risk and could be applied directly to risk management.
