This study concentrates an the trail of the CNU(Chungnam National University) forest. The amount of use and the pattern of damage are considered, as well as the extent of environmental damage. Finally, some managerial strategies are proposed in connection with sustainable maintenance. The trail of the university forest is composed of three sections; one is the neighborhood park and the Institute of Information Technology/Communications, the second is the Institute of Information Technology/Communications and the Dormitory, and the third section is the Dormitory and the Foreign prof's Apt. The total length of the trail is 2.6km. The daily amount of use is 1,269 visitors per day. The amount of using increased three times the amount of that in 1998. This study shows the pattern of damage of the trail in the order of root-exposure, widening, rock-exposure, deepening and the divergence in the frequency of occurrence of all these factors. Environmental damage is also graded thus: grade 3 is 27.4m, grade 4 is 0.8m, grade 5 is 1.5m, and grade 6 is 0.2m. Accordingly, some managerial strategies were proposed in connection with the sustainable trail maintenance.

Background: The purpose of this study was to evaluate the recurrence of hepatocellular carcinoma and the survival rate of patients who received radiofrequency ablation (RFA) after transarterial chemoembolization (TACE) with that of patients treated with TACE or RFA alone. Methods: Two-hundred and one patients with HCC were consecutively enrolled at Seoul St. Mary`s hospital between Dec, 2004 and Feb, 2010. Inclusion criteria were a single HCC≤5.0 cm or up to three HCCs≤3.0 cm, with no vascular invasion or extrahepatic metastasis. In all, HCC patients (n=87) who had undergone RFA after TACE and those who received TACE (n=71) or RFA only (n=43) were analyzed. Propensity scores were generated to select from each arm of the study. Results: Median follow-up periods were 33.3 months (6.8-80.9 months). The recurrence rates at 1, 3, and 5 years in the TACE+RFA and RFA groups were similar (6, 33, and 54%; and 10, 31, and 48% respectively); however, those in the TACE group were higher (17, 58, and 78%, respectively). In the TACE+RFA group, the local recurrence rates were significantly lower compared with the RFA group (P=0.034). The overall survival rates at 1, 3, and 5 years in the TACE+RFA group (98, 95, and 90%, respectively) were superior to those in the TACE or RFA groups (98, 90, and 83%; 94, 84, and 71%; P=0.064, 0.011, respectively). In a multivariate analysis of overall survival using a Cox regression model, combination treatment was a significant independent factor for survival compared to RFA and TACE monotherapy (HR, 0.371; 95% CI, 0.141-0.973; P=0.0371, HR, 0.476; 95% CI, 0.230-0.986; P=0.046, respectively) Conclusion: The combination of TACE and RFA is an effective treatment for early-stage HCC and results in lower local recurrence and better overall survival rates than those achieved by RFA or TACE alone.

Aims: Biopsy is still the gold standard for the diagnosis of nonalcoholic steatohepatitis (NASH) but the definition may vary in evaluation of biopsies for clinical trials. Recently, a scoring system (steatosis, activity, fibrosis[SAF]) allowing the use of an algorithm (fatty liver inhibition of progression [FLIP]) reported for the classification of liver injury in morbid obesity. We evaluated the application of SAF score and FLIP algorithm in Korean patients with nonalcoholic fatty liver disease (NAFLD). Methods: We analyzed the 126 patients with biopsy-proven NAFLD in 5 centers in Korea from Aug, 2008 to April, 2016. Results: In total study populations, 56 patients (44.4 %) were diagnosed to NASH, 70 (55.6%) as NAFLD including 60 patients of a gray zone (NAS 3-4) according to NAS scoring system. Based FLIP algorithms, 72 patients (57.1 %) were categorized as NASH, 54 (42.9 %) as NAFLD. 21 patients (35%) in gray zone (NAS 3-4) and 5 patients (NAS ≥5) were categorized as NASH and steatosis, respectively. The activity score (ballooning+ lobular inflammation) enabled discriminating NASH. All patients with NASH had A ≥3, whereas 3 patients (5.2%) with A2 had NASH. Especially, the presence of ballooning in activity score was the significant factor to discriminate NASH and steatosis. This activity score was also closely correlated with both alanine aminotransferase (ALT) and aspartate aminotransferase (AST) and Fragmented cytokeratin-18, respectively (P=0.000, 0.023, 0.006 respectively). Fibrosis grade by SAF score was significantly correlated with NAFLD fibrosis score and fibroscan (P=0.026, 0.000, respectively). Conclusions: The FLIP algorithm and SAF score system in the NAFLD may provide the favorable tools in Korean patients. Among the SAF score, the ballooning of hepatocyte may be an important factor to discriminate NASH and NAFLD, although it is one of the major limitations of liver biopsy.

Choi, Jun-Yong,Jung, Hee-Jae,Kim, Jong-In,Lee, Myeong Soo,Kang, Kyung-Won,Roh, Young-Lae,Choi, Sun-Mi,Jung, Sung-Ki Informa Healthcare 2010 The Journal of asthma Vol.47 No.7
<P><I>Objective</I>. This trial aimed to evaluate the feasibility of estimating the effectiveness of acupuncture on asthmatic patients under conventional medical management. <I>Participations and Methods</I>. A prospective randomized, patient/assessor-blinded, sham acupuncture-, and waiting list-controlled pilot trial was conducted. Forty-five eligible asthmatic participants underwent a 1-week run-in period and were then randomized into one of three groups: an active acupuncture group, a sham acupuncture group, and a waiting list group. They were instructed to maintain the use of antiasthmatic medications. Needling was administered three times per week for 4 weeks with a 2-week follow-up in the active and sham acupuncture groups. The primary outcome was daily morning peak expiratory flow (PEF) and the secondary outcomes included forced expiratory volume one second (FEV<SUB>1</SUB>), quality of life questionnaire for adult Korean asthmatics (QLQAKA), transition dyspnea index (TDI), serum eosinophil count, and total serum immunoglobulin E (IgE). <I>Results</I>. No significant differences in the between- or within-group values of weekly average PEF (recorded daily in the morning) and FEV<SUB>1</SUB> were found. For QLQAKA and TDI, the active acupuncture group showed a significant improvement over the waiting list group at 2, 4, and 6 weeks after randomization. <I>Discussion</I>. Acupuncture as an adjunct therapy to conventional medical care does not seem to affect pulmonary function in asthmatic patients. However, 12 sessions of acupuncture treatment during 4 weeks showed a favorable effect on the quality of life in adult asthmatic patients. Further large trials assessing the effectiveness of acupuncture on the quality of life and symptoms in asthmatic patients are needed.</P>

COS 조작봉은 선로의 사고나 설비교체 또는 수리 등이 필요할 때 활선상태에서 COS를 개폐하기 위한 장비로서 보통 절연특성 및 강도가 우수하고 경량소재인 FRP(Fiberglass Reinforced Plastics)로 제작된다. 따라서 특고압 선로에서 작업 중 안전사고를 예방하기 위해 사용되는 장비인 만큼 안전거리 확보와 작업의 편리성을 고려하여 직접 조작봉을 연장하여 사용할 수 있도록 다단으로 제작되며, 조작봉의 크기는 작업 조건에 따라 길이를 선택하여 사용할 수 있도록 2, 4, 6m급 등 길이에 따른 종류별로 생산되고 있다. 이러한 COS 조작봉의 사용특징은 장소와 시간에 관계없이 사용이 가능해야 하고, 특정한 사정에 의해선 작업자 혼자서 사용할 수 있도록 조작봉과 일체된 조명장치의 필요성이 항상 제기되어 왔던 문제이다. 본 논문에서는 이러한 문제점에 주안을 두고 조작봉과 일체된 전계검출에 의한 발광동작을 제어할 수 있는 발광형 COS 조작봉에 대해 각각의 구성별 요소들을 분석하고자 한다.
