To investigate the effects of strenuous physical exercise on commonly used hematological markers in subjects the intensive long running. Blood samples were obtained from nineteen participants in a 622 km ultra-marathon race before, 300 km and immediately after completion of the 622 km ultra-marathon. Samples were analyzed for total white cell count (WBC) and differential, total red cell count (RBC), hemoglobin, hematocrit, mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), red cell distribution width (RDW), platelets, mean platelets volume (MPV), platelets distribution width (PDW). Significant increases were found in WBC, neutrophil and platelets at 622 km compared to the pre-race. RBC, hemoglobin and hematocrit decreased statistically significantly the race at 300 km and 622 km compared to pre-race. A wide range of hematological perturbations occur during 622 km ultra-marathon running but it was physiological changes within a reference range. The 622 km ultra-marathon is less likely to cause clinically significant hematologic changes in athletes.

The satellite payloaded on the 2nd stage of KSLV-I is planned to perform CCAM(Contamination and Collision Avoidance Maneuver) not to collide with KM(Kick Motor). At the moment, the satellite should pass through low density environment not to be contaminated by KM plume due to residual thrust. Therefore, it is necessary to predict the flow field of KM plume by residual thrust. In this paper, DSMC (Direct Simulation Monte-Carlo) method, which is widely accepted to simulate in rarefied regime, is used to compute the density field of KM plume by residual thrust and the result of DSMC simulation was compared with that of FLUENT to validate it.

Objectives: The objectives of this study are to determine both what information Korean Medicine(KM) doctors want from medical classics and how classic KM knowledge should be structured. Methods: KM doctor survey was conducted in October 2012 via E-mail to determine what information Korean Medicine doctors want to collect from a larger volume of existing classics. Specialist survey was made in October 2012 through questionnaire and 8 workshops were held between April 2012 ~ February 2013 to discuss how to reorganize classic KM knowledge. Results: With two surveys and 8 workshops, we built a conceptualization of the classic KM knowledge system for KM practice. KM doctors wanted to engage with the design of KM knowledge system informed by authentic medical classics, and hoped that more information on common disorders would be added to the table of contents of classic KM books than now. A comprehensive knowledge system was also required to maximize information sharing. Conclusions: Future KM knowledge systems need to be more comprehensive and include more information about disorders with which patients commonly consult KM doctors.

Objectives: Although Korean Medicine (KM) subsidized by the National Health Insurance (NHI) has been used for a long time, there has been no active analysis using claims data. Therefore, the purpose of this study was to examine the NHI KM utilization trend using NHI statistics and to measure the level of market concentration by year. Methods: By restructuring the contents of NHI Statistics for Pharmaceuticals for 2010-2019, the claim cases, costs, and annual growth rates of KM were demonstrated by year, sex, age group, region, therapeutic group, and KM treatment. The proportion of highly used k treatments in cost was calculated as the concentration ratio (CR) k and its trend by year was investigated. Results: In 2019, the NHI cost on KM amounted to ₩38.2 billion KRW, increasing by 11.6% per year on average in 2010-2019. Notably, KM was used more frequently among women and patients aged ≥ 65 years, and the mixed formulation accounted for 95% of the total cost of KM. The CR of the simple formulation increased rapidly, whereas that of the mixed formulation remained constant. In 2019, three simple formulation treatments- peony, licorice, and ginseng- accounted for 93.8% of the total cost for KM (CR3 = 93.8%). Conclusion: NHI KM is rapidly increasing. Investigating the CR of KM confirmed that KM prescriptions have been concentrated in small numbers over the past 10 years.

Purpose: The objective of this study is to analyze the activities of muscles importantly functioning when walking with different inclinations and speeds of a treadmill, in order to provide basic data on walking exercise using a treadmill. Method: The selected subjects of this study were 16 men and women who had lower extremity injury. A treadmill was used to provide the activation of muscle, and the electromyography was used to analyze the muscle activity variables. The Biodex was used to measure the value of maximum isometric contraction. The inclinations of the treadmill were 0%, 5% and 10%, respectively, and its speeds were 2Km/h. 3Km/h, 4Km/h, 5Km/h, and 6Km/h, respectively. Result: For quadriceps femoris muscle and trunk muscle, there were significant differences in muscle activity when different speeds were applied at 0%, 5% and 10% inclinations.(p<0.05) The activity of vastus medialis muscle was 9.78% at 0% inclination and 2km/h speed, whereas it was 9.32% at 0% inclination and 3km/h, which was slightly lower. The activity of erector spinae muscle was 24.93% at 0% inclination and 2km/h speed, whereas it was 24.84% at 0% inclination and 3km/h, whereas it was 23.99% at 0% inclination and 4km/h, which was slightly lower. The activity of vastus medialis muscle was 11.89% at 10% inclination and 2km/h speed, whereas it was 10.65% at 10% inclination and 3km/h, which was slightly lower. The activity of rectus femoris muscle was 10.26% at 10% inclination and 2km/h speed, whereas it was 9.77% at 10% inclination and 3km/h, which was slightly lower. Conclusion: It was found that the activities of trunk muscle and quadriceps femoris muscle increase as the inclination and the speed of a treadmill increase during treadmill walking.

The aim of this study was to investigate the impact of participation in the 622 km hyper-ultra-marathon on hepatic metabolism and renal function in middle-aged men. Healthy middle-aged male amateur ultra-marathoners between the ages of 40 and 60. Blood was collected at the pre-race, immediately after 300 km, 622 km hyper-ultra marathon race, 72 hours (3 day) and 144 hours (6 day) after the race, AST (aspartate aminotransferase), ALT (alanine aminotransferase), ALP (alkaline phosphatase), ${\gamma}$-GTP (gamma glutamyl transferase), T-Bil (total bilirubin), D-Bil (direct bilirubin), T-protein (total protein), albumin, uric acid, BUN (blood urea nitrogen), creatinne were analyzed. ALP was significantly increased at 300 km, 622 km, day 3 and day 6 than the pre-race. ${\gamma}$-GTP, T-protein, albumin, uric acid, BUN and creatinine were not significantly different between the distances and the recovery period respectively. AST and ALT were significantly increased at 300 km, 622 km, day 3 and day 6 than the pre-race, respectively (P<0.05) at day 3 and day 6 they showed significant decrease from 300 km and 622 km, respectively (P<0.05). T-Bil and D-Bil increased significantly at 300 km and 622 km, respectively (P<.05) and significantly decreased at day 3 (P<0.05) compared to the pre-race, at day 3 and day 6 they were decreased significantly than 300 km and 622 km, respectively (P<0.05). In conclusion, no disturbance of renal function was observed according to the distances and between the recovery period of 622 km hyper-ultra marathon race, but reversible hepatocyte function could be degraded and some hemolysis of blood vessels was induced.

The purpose of this paper is to explore the strategy of future Korean medicine(KM) clinical research through the study on the proposals for KM clinical research worldwide. In this study, the papers published in English through Pubmed were investigated mainly. Among them, we analyzed the methodological proposals from the clinical research papers that were published in the KM related fields. Various proposals for improving the problems in KM clinical studies are as follows. First, KM clinical research should be designed based on understanding for the theory, backgrounds, paradigms and worldviews of KM. In addition, considering the model validity, KM clinical research model should include the diagnosis, interventions and outcomes measurement methods reflecting the characteristics and real practice in KM. The internal validity and external validity should be also taken into account. One of the most important thing is to identify the contents about various and complex 'real practice' in KM. A prospective observational study was suitable for the purpose of this study. Finally, we suggested a few improvement directions for RCTs studies in KM. First, we would be able to improve the quality and the internal validity in KM clinical research using the checklists of CONSORT(Consolidated Standards for Reporting Trials) Statement and STRICTA(Standards for Reporting Interventions in Clinical Trials of Acupuncture). Second, we could use various clinical research methods and the modified research of RCTs such as PCT(pragmatic clinical trial) to reflect the characteristics of actual KM practice. Consequently, we would be able to improve the external validity. Third, the KM diagnosis and outcomes measurement methods should be developed based on an actual KM practice and it should reflect a real practice. The 'pattern identification(辨證)' is the core to KM diagnosis. But in order to be applied to the clinical research, the pattern identification(辨證) should be objectified and standardized. Future KM clinical research model should reflect the characteristics and a real practice in KM. In addition, it should include the advantage of rigorous RCTs research.Specially, the diagnosis, interventions and outcomes measurement methods in KM clinical research should reflect this view.

In order to understand the transfer behavior of a particular gene in water environments, kanamycin resistance ($Km^r$) gene was tracked by Southern hybridization with DNA probe in its conjugal transfer. A $Km^r$ natural bacterial isolate and genetically modified microorganisms (GMMs) constructed from the isolate were used as donor for conjugal transfer of the $Km^r$ gene. The transfer frequencies of the $Km^r$ gene from GMM strains were generally 10 to 100 times higher than those from the natural isolate. The conjugants obtained from GMM strains in LB broth had more plasmids newly appeared, and particularly the conjugants in A Wand FW waters revealed more rearrangement in their plasmids as a function of conjugation time. When plasmids of the conjugants obtained in LB broth were Southern hybridized with DNA probe of the $Km^r$ gene, the $Km^r$ plasmids in the conjugants were detected at the same position of the plasmids in donor cells, in spite of the fact that the plasmids were highly rearranged in conjugant cells. But the $Km^r$ plasmids in the donor of DKI and DKC601, and DKC600 were not identified in the conjugants obtained after 50 h conjugation in AW and after 30 h in AW, respectively. The size of the $Km^r$ plasmids showing hybridization signal were a little changed in the conjugants obtained in A Wand FW waters. Therefore, the method of Southern hybridization with DNA probe was proved to be very specific and useful for tracking of particular genes in water environments.
