The flora in the region of Mt. Sobaeksan National Park ($N36^{\circ}50^{\prime}-37^{\circ}50^{\prime}$, $E128^{\circ}20^{\prime}-128^{\circ}43^{\prime}$) was surveyed from April of 2005 to October of 2011. The vascular plants from 27 field surveys were revealed to total 869 taxa, comprising 112 families, 429 genera, 756 species, four subspecies, 91 varieties and 18 forms. Sixty-eight taxa were the first records from this region. This field study discovered significant plants in various categories. Korean endemic plants numbered 25 taxa, and 18 taxa designated by the Korean Forest Service as rare plants were investigated in this region. The taxa in category II of rare and endangered plants and higher than the third degree among the floristic regional indicator plants designated by the Korean Ministry of the Environment were three taxa and 75 taxa, respectively. From a geographical perspective, limited distribution of Saxifraga octopetala, Corydalis grandicalyx, Aegopodium alpestre, and Polygonatum acuminatifolium at a latitude higher than that of Sobaeksan National Park suggest that Sobaeksan National Park might be the limit line of the distribution of the taxa. Stewartia koreana demonstrate a reversed pattern from the taxa above, occurring at a latitude lower than that of Sobaeksan National Park. In addition, naturalized plants of 53 taxa were recorded.

The purpose of this study is to verify how 7 sentiment domains extracted through sentiment analysis from social media have an influence on business performance. It consists of three phases. In phase I, we constructed the sentiment lexicon after crawling 45,447 pieces of VOC (Voice of the Customer) on 26 auto companies from the car community and extracting the POS information and built a seven-sensitive domains. In phase II, in order to retain the reliability of experimental data, we examined auto-correlation analysis and PCA. In phase III, we investigated how 7 domains impact on the market share of three major (GM, FCA, and VOLKSWAGEN) auto companies by using linear regression analysis. The findings from the auto-correlation analysis proved auto-correlation and the sequence of the sentiments, and the results from PCA reported the 7 sentiments connected with positivity, negativity and neutrality. As a result of linear regression analysis on model 1, we indentified that the sentimental factors have a significant influence on the actual market share. In particular, not only posotive and negative sentiment domains, but neutral sentiment had significantly impacted on auto market share. As we apply the availability of data to the market, and take advantage of auto-correlation of the market-related information and the sentiment, the findings will be a huge contribution to other researches on sentiment analysis as well as actual business performances in various ways.

Purpose: The purpose of this study was to examine the effect of tooth-brushing oral care on oral health and ventilator-associated pneumonia of patients in Intensive Care Unit (ICU). Methods: A total of 74 participants were recruited from a medical, surgical, or neurosurgical ICU at S Hospital in Seoul, Korea, from September of 2010 to January of 2011. An experimental group (n= 36) received oral care with tooth-brushing while a control group (n=38) received oral care with cotton ball and gauze. In both group, the oral care was done three times a day at least one minute for 7 days. Oral health was examined by the Modified Oral Assessment Guide before the intervention and each night. Results: There is no difference between the groups in aspect of passage of time (p = .603), interaction between time and intervention (p =.300), the performance intervention (p = .766), and the incidence of VAP (p = .486). Conclusion: The effect of oral care with tooth-brushing on oral health and VAP was not different from that of usual oral care in ICU. However, further study is necessary due to high attrition in this study.

Tunnel is a semi-closed structure similar to underground space where the smoke generated from fire fills the space fast while escaping from the space slow. Because of such characteristics, when the fire breaks out by traffic accident, the vehicles are jammed making it difficult for the people to evacuate from the scene as well as for the fire engine to gain access to the scene. For such reasons, tunnels are globally categorized into some disaster classes for differentiated facilities and operation approaches. In Korea, less than a 1 km-long tunnel accounts for 80.0% and such a short tunnel which is categorized into Class III is not required to have smoke control system. In this study, a full-scale fire test was conducted in a bid to apply air curtain system using heat-resistant sirocco fan to a less than 1 km-long tunnel. To that end, heat resistance test to verify the normal operation at $250^{\circ}C$ for 60 minutes was conducted. Consequently, despite of rapid rising-temperature and increasing-carbon dioxide inside the air curtain (direction of fire in tunnel), initial condition was found to have been sustained outside the air curtain (opposite direction of fire in tunnel).

Purpose: The aim of this study was to compare the short-term surgical and long-term functional outcomes of Billroth I, Billroth II, and Roux-en-Y reconstruction after laparoscopic distal gastrectomy. Materials and Methods: We retrospectively collected data from 697 patients who underwent laparoscopic distal gastrectomy for operable gastric cancer between January 2009 and December 2012. The patients were classified into three groups according to the reconstruction methods: Billroth I, Billroth II, and Roux-en-Y. The parameters evaluated included patient and tumor characteristics, operative details, and postoperative complications classified according to the Clavien-Dindo classification. Endoscopic findings of the remnant stomach were evaluated according to the residue, gastritis, bile (RGB) classification and the Los Angeles classification 1 year postoperatively. Results: Billroth I, Billroth II, and Roux-en-Y were performed in 165 (23.7%), 371 (53.2%), and 161 patients (23.1%), respectively. Operation time was significantly shorter ($173.4{\pm}44.7$ minute, P<0.001) as was time to first flatus ($2.8{\pm}0.8$ days, P=0.009), time to first soft diet was significantly faster ($4.3{\pm}1.0$ days, P<0.001), and postoperative hospital stay was significantly shorter ($7.7{\pm}4.0$ days, P=0.004) in Billroth I in comparison to the other methods. Postoperative complications higher than Clavien-Dindo grade III occurred in 61 patients (8.8%) with no statistically significant differences between groups (P=0.797). Endoscopic findings confirmed that gastric residue, gastritis, bile reflux, and reflux esophagitis were significantly lower in Roux-en-Y (P<0.001) patients. Conclusions: Roux-en-Y reconstruction after laparoscopic distal gastrectomy for middle-third gastric cancer is beneficial in terms of long-term functional outcome, whereas Billroth I reconstruction for distal-third gastric cancer has a superior short-term surgical outcome and postoperative weight change.

Objectives : The purpose of this study was to identify the effect of Dokwal-tang(Duhuo-tang) and Jungsongouhyul Pharmacopuncture on pain control and nerve regeneration after crush injury in rat sciatic nerve. Methods : Animal model was produced through right sciatic nerve crush injury and they were randomly divided into four groups; Group I: no treatment control group; Group II: experimental group treated with Dokwal-tang(Duhuo-tang); Group III: experimental group treated with Jungsongouhyul Pharmacopuncture; Group IV: experimental group treated with Dokwal-tang(Duhuo-tang) and Jungsongouhyul Pharmacopuncture. For the pain assessment, this study was observed the paw withdrawal latency(PWL) and immunoreactivity on the substance-P. For the nerve regeneration assessment, the sciatic functional index(SFI) and immunoreactivity on the GAP-43 were measured. Results : 1. In the pain assessment, the PWL of experimental groups were significantly higher than control group and group IV was significantly higher than other groups. 2. In immunohistochemical response of substance-P, as time passes, all groups had decreased immunoreactivity gradually. Specially, group IV was observed the lowest immunoreactivity. 3. In the assessment of SFI, the SFI of experimental groups were significantly higher than control group. 4. In immunohistochemical response of GAP-43, all groups had higher GAP-43 immunoreactivity at the 14 days from post-injury and at the all days, control group was observed most lower immunoreactivity and group IV was observed most higher immunoreactivity. Conclusions : These results of this study suggest that Dokwal-tang(Duhuo-tang) and Jungsongouhyul Pharmacopuncture was related with pain inhibition and motor nerve recovery, and decreased substance-P expression and increased GAP-43 expression after sciatic nerve crush injury.

Background: The aim of this study was to determine the effectiveness of self-efficacy promoting pulmonary rehabilitation in patients with chronic obstructive pulmonary disease (COPD). Methods: thirty six patients, with clinically stable COPD were randomly assigned: 18 to a rehabilitation group and another 18 as a control group, The subjects participated in a the self-efficacy promoting pulmonary rehabilitation program for 8 weeks. This program consisted of education, breathing retraining, exercise training, relaxation and counseling. The control group received education only. The outcome variables were self-efficacy, dyspnea, exercise endurance, pulmonary function, and quality of life. Dyspnea was measured using the modified Borg scale. Exercise endurance was measured by the six minute walking distance. The quality of life was measured by the quality of life index for pulmonary disease patients. Results: In the rehabilitation group after performing the self-efficacy promoting pulmonary rehabilitation program, the self-efficacy score, exercise endurance, and quality of life score were higher than the control group (p=0.007, p=0.038, and p=0.039, respectively). and the exertional dyspnea score was significantly lower than controls(p=0.045). However, the dyspnea score and FEV1 were similar after performing the self-efficacy promoting pulmonary rehabilitation program. Conclusion: The self-efficacy promoting pulmonary rehabilitation program is effective to in improve self-efficacy, exertional dyspnea, exercise endurance and quality of life in patients with COPD.

In order to quantify the effect of the newly established the Total Water Load Management System in Sapgyo watershed, this study predicted the achievement of the target water quality at each unit watershed and the water quality according to the flow section. The HSPF model, which is the watershed runoff model, was constructed and operated based on 2015, and the water quality was predicted by inputting the loads in final target year(2030). The Load Duration Curve (LDC) was created using the simulated results of base year and target year. As a result of plotting water quality by flow conditions, it was simulated to be close to the BOD target with a difference of 0.1 ~ 0.2 mg/L in all three watersheds during the mid-range flow interval (40 ~ 60%). In case of T-P, although the target water quality was not set, the water quality was improved by Cheonan A 46%, Kokgyo A 29% and Namwon A 25%. The Muhan and Sapgyo river basins meet the target grade of middle-watershed standards. The improvement effect will be positive, as water quality, which achieves the target of Total Load Management System and the target grade of the middle-watershed standards will be expected to flow into the Sapgyo lake.
