To find out the effects or Chungsangboha-tang on allergic asthma. We had checked change of respiratory pattern, frequency ratio of abnormal respiratory rate, change of eosinophilic infiltration in tracheal mucosa in experimental animal which was evoked allergic asthma then got the following results. 1. There was no significant difference in individual respiratory pattern between sample group which was treated with Chungsangboha-tang and control group. 2. To compare with control group, statistically sample group was showed significant decrease(p<0.05) frequency ratio of abnormal repiratory rate which was mean of expiratory respiration difficulty. 3. To compare with control group, statistically sample group, which was treated with Chungsangboha-tang, showed significant decrease(p<0.05) eosinophilic infiltration in tracheal mucosa.

The land cover classification by using remotely sensed image becomes necessary and useful for hydrologic and water quality related applications. The purpose of this study is to obtain land classification map by using remotely sensed data : Landsat TM and KOMPSAT-1 EOC. The classification was conducted by maximum likelihood method with training set and Tasseled Cap Transform. The best result was obtain from the Landsat TM merged by KOMPSAT EOC, that is, similar with statistical data. This is caused by setting more precise training set with the enhanced spatial resolution by using KOMPSAT EOC(6.6m×6.6m).

The purpose of this study is to estimate temporal soil loss change according to long-term land cover changes using GIS and RS. Revised USLE(Universal Soil Loss Equation) factors were made by using point rainfall data, DEM(Digital Elevation Model), soil map and land cover map. Past two decades land cover changes were traced by using Landsat MSS and TM data. Soil loss in 2000 increased 6.3 kg/m<sup>2</sup>/yr compared with that in 1983. This was mainly caused by the increased upland area.

<P>Insulin resistance is a major characteristic of obesity and type 2 diabetes, but the underlying mechanism is unclear. Recent studies have shown a metabolic role of capsaicin that may be mediated <I>via</I> the transient receptor potential vanilloid type-1 (TRPV1) channel. In this study, TRPV1 knockout (KO) and wild-type (WT) mice (as controls) were fed a high-fat diet (HFD), and metabolic studies were performed to measure insulin and leptin action. The TRPV1 KO mice became more obese than the WT mice after HFD, partly attributed to altered energy balance and leptin resistance in the KO mice. The hyperinsulinemic-euglycemic clamp experiment showed that the TRPV1 KO mice were more insulin resistant after HFD because of the ∼40% reduction in glucose metabolism in the white and brown adipose tissue, compared with that in the WT mice. Leptin treatment failed to suppress food intake, and leptin-mediated hypothalamic signal transducer and activator of transcription (STAT)-3 activity was blunted in the TRPV1 KO mice. We also found that the TRPV1 KO mice were more obese and insulin resistant than the WT mice at 9 mo of age. Taken together, these results indicate that lacking TRPV1 exacerbates the obesity and insulin resistance associated with an HFD and aging, and our findings further suggest that TRPV1 has a major role in regulating glucose metabolism and hypothalamic leptin’s effects in obesity.—Lee, E., Jung, D.

이 연구는 셰일가스 개발을 위한 수압파쇄 미소지진 현장계측 기술 확보를 목표로 하고 있다. 이를 위해 셰일층이 부존하는 현장을 선정하여 수압파쇄 실험 및 인공발파 실험을 실시하여 미소지진 계측을 수행하였으며 이를 통해 현장계측에서 고려되어야 할 사항을 검토하였다. 수압파쇄시 계측된 미소지진 자료는 진폭이 0.001 mm/sec ~ 0.003 mm/sec 정도로 그 에너지가 대단히 적었으며 주파수 내용은 5 Hz ~ 20 Hz 범위였다. 인공발파시 계측된 미소지진 자료는 수압파쇄보다 대단히 큰 진폭(0.011 mm/sec ~ 0.302 mm/sec)을 나타내었으며 주파수 범위도 5 Hz ~ 2 kHz로 넓게 나타났다. 미소지진 현장계측 설계를 위해 이론적인 자료 및 현장 경험 등을 토대로 미소지진 현장계측에 적합한 센서 및 계측장비의 선정, 수진기 배열 또는 배치 범위 등에 대해 고찰하였다. The purpose of this study is to ensure microseismic data acquisition technique for hydraulic fracturing imaging at the site of shale gas development. For this, microseismic data acquisition was performed during hydraulic fracturing and artificial blasting at a site bearing shale layers. Measured microseismic event data during the hydraulic fracturing have the very small amplitude of 0.001 mm/sec ~ 0.003 mm/sec and the frequency contents of 5 Hz ~ 20 Hz range. Meanwhile microseismic event data acquired during artificial blasting have the bigger amplitude (0.011 mm/sec ~ 0.302 mm/sec) than hydraulic fracturing event data and their frequency contents have the range of 5 Hz ~ 2 kHz. For microseismic data acquisition design, the selection of appropriate instrumentation including sensors and the recording system, the determination of sensor array and the deployment range were investigated based on the theoretical data and field application experiences.

Purpose: The rate of malignancy in the follicular neoplasm (FN) or Hürthle cell neoplasm (HCN) of the thyroid gland is estimated as approximately 20∼30%. Fine-needle aspiration biopsy (FNAB) and frozen section examination are restricted in differentiating between benign and malignant. The aims of this study are to compare the differences of clinicopathologic features and to determine the risk factors for malignancy in patients with FN or HCN. Methods: A retrospective study was conducted of patients with FN or HCN who were diagnosed by FNAB, and underwent surgery at our institution between Jan. 2005 to Jun. 2010. We analyzed the risk factors for malignancy and the differences of clinicopathologic features in patients with FN or HCN. Results: A total of 290 patients were enrolledin this study; 160 (55.2%) patients underwent thyroidectomy, 97 (60.6%) patients had FN, and 63 (39.4%) had HCN. Forty one (25.6%) patients were diagnosed as malignancy of these, 22 (22.7%) patients were FN and 19 (30.2%) were HCN (P=0.29). Two (2.1%) patients with FN and 10 (15.9%) with HCN (P=0.002) comcomitant papillary thyroid carcinoma were indentified by FNAB. Classification of nodules according to ultrasonographic findings in both neoplasms (P<0.05) and galectin-3 in FN (P<0.05) were predictive factors for malignancy. In addition, galectin-3 was a predictive factor for malignancy in indeterminate nodules on ultrasonography (USG) (P=0.028). Conclusion: Classification of nodules according to ultrasonographic findings and galectin-3 expression is helpful in predicting carcinoma of patients with FN or HCN.

Since pandemic influenza was declared by WHO at June 2009, severe pandemic influenza cases were reported among pregnant, obese, immunocompromised patients including transplant candidates and recipients were reported. Here we report two cases of pandemic influenza (H1N1 2009) with respiratory distress syndrome in adult patients with kidney transplantation. They were successfully treated with combination of antiviral therapy including high dose oseltamivir. Although clinical symptoms and signs were improved immediately when anti-viral therapy was started, radiologic finding resolved after several weeks.
