Superior vena cava syndrome (SVCS) is usually caused by extrinsic compression or invasion of the superior vena cava (SVC) by malignant tumors involving mediastinal structures. Although thymomas are well-known causes of SVCS, cases of SVCS caused by malignant thymomas protruding into adjacent vessels draining the SVC with thrombosis have been very rarely reported worldwide. We experienced a 39-year-old female patient with SVCS that developed after the direct invasion of the left brachiocephalic vein (LBCV) and SVC by an anterior mediastinal mass with a high maximum standardized uptake value on the chest computed tomography (CT) and positron emission tomography-CT. Based on these results, she underwent en bloc resection of the tumor, including removal of the involved vessels, and was eventually diagnosed as having a type B2 thymoma permeating into the LBCV and SVC. We present this case as a very rare form of SVCS caused by an invasive thymoma.
This study examines the character of "Tencel" named as Ecology Fiber and investigates the fitness of it as the textile and the satisfaction in dress when its fastness is compared with that of Rayon classified into Celulose textile. Dye experiment selected 100% Tencel, Rayon for the samples, which were dyed into the direct dye and Turky Blue and Blue of the rective dye and were washed twelve times by the automatic washer. After that, the dye experiment examines the light, laundering, perspiration, rubbing and the composite fastness of the perspiration and hight in the lists of the dye fastness. The results are as follows: 1. The experiment of the color fastness, especially in T-blue of the direct dyestuff, requiring the twelve times-repeatedly-washing by the detergent says that the color fastness of Tencel is superior to that of the cellulose textile ; Rayon. 2. The experiment of the light fastness says that the fastness of Tencel is superior to that of Rayon. 3. The experiment of the laundering fastness says that all of Tencel, Rayon shows the excellent result in the direct dye than in the reactive dye. 4. The experiment of the rubbing fastness says that although Tencel, Rayon show the remarkable result in the desiccant experiment than in the humid one, the rubbing fastness of Tencel is superior to that of others. 5. The experiment of perspiration fastness says that Tencel, Rayon have the closely tightened tendency not to be altered through the acid and alkali perspirations. 6. The experiment of the composite fastness of perspiration and light indicates that the artifical perspirations, though the light lets the fastness of textiles weeken, do very slightly make them loosen, which does not offer the outstanding result. This whole result show that the fastness of Tencel is superior to that of Rayon. The Korean Fiber Enterprise in clothing should make the new and ecological fiber "Tencel" by means of the large amount of investment, and the technique of handing and controlling about it, considering that the dangerous needle of environmental pollution has been slackening the close-related ecological knots of the global environment. global environment.
Background: A stellate ganglion block (SGB) causes increased blood flow in the maxillofacial region, exhibiting the potential for regenerative effects in damaged tissue. The focus of this study was to understand the efficacy of SGB for regenerative effects against nerve damage. A rat model of the superior cervical ganglion block (SCGB) was created instead of SGB, and facial blood flow, as well as sympathetic nervous system function, were measured. Methods: A vertical incision was made on the left side of the neck of a Wistar rat, and a 5-mm resection of the superior cervical ganglion was performed at the back of the bifurcation of the internal and external branches of the left common carotid artery. Blood flow in the skin at the mandibular angle and mean facial temperature were measured using a laser-Doppler blood flow meter and a thermographic camera, respectively, over a 5-week period after the block. In addition, the degree of ptosis and miosis were assessed over a period of 6 months. Results: The SCGB rat showed significantly higher blood flow at the mandibular angle on the block side (P < 0.05) for 3 weeks, and significantly higher skin temperature (P < 0.05) for 1 week after the block. In the SCGB rat, ptosis and miosis occurred immediately after the block, and persisted even 6 months later. Conclusions: SCGB in rats can cause an increase in the blood flow that persists over 3 weeks.

The experiment was conducted to investigate the potential for environmentally friendly cultivation of cv. Haryeong, which was bred by the National Institute of Highland Agriculture in 2006, through evaluation of the late blight field resistance at the farmer's practices level. cv. Haryeong showed higher field resistance to late blight as 590.3 in mean Area Under the Disease Progress Curve (AUDPC) during the cultivation period than cv. Superior as 1377.7 in AUDPC. However there was no observed different trend among the experimental treatments. Mean of tuber yield of cvs. Haryeong and Superior were 2,870 kg/10a and 2,301 kg/10a, respectively, and in all experimental treatments Haryeong was 25% higher than those of Superior. Mean of dry matter content of Haryeong and Superior were 18.1% and 16.1%, respectively, and there were no significant differences among the experimental treatments. cv. Haryeong was confirmed as a suitable cultivar for environmentally friendly cultivation in this experiment. In the future, additional research on fertilization and disease management will be required.
This study is to excavate superior fishing communities by applying the Ostrom (1990)'s principles of sustainable and successful use of common goods. Ostrom(1990)'s principles are (1) clearly defined boundaries (2) congruence between appropriation and provision rules and local conditions, (3) collective choice arrangements (4) monitoring (5) graduated sanctions (6) conflict-resolution mechanism (7) recognition of rights to organize by external government authorities (8) nested enterprises. The survey was carried out under the individual interview method of 15 fishing village members in 32 fishing communities with the government's fishery environment improvement and fishery creation projects. The total effective samples are 477. These data were analyzed. The analysis result shows that 24 fishing villages are selected among the 32 fishing communities in the samples, including Nanji, Sanghwang, Songseok, Sinshido, Jukyo, Jinsan, Changli, Pado, Beopsan, Rahyang, Palbong, Woongdo, Daehwang, Sapsi, Chido, Jinri, Daeri, Songgak, Joongwang, Ojii, Doripo, Doseong, Mongsan 1ri and Songnim as superior fishing villages. The results of this study have limitation that may vary depending on the rigor of the criteria in the process of deriving good fishing communities. Despite this limitation, this study has expanded existing research focused on validating the theoretical applicability of the framework through case analysis of specific fishing communities to objectively and quantitatively to many fishing communities. The results of this study are expected to contribute to the creation of conditions in which fishermen can continue to manage their fishing grounds and stand on their own feet by presenting the framework and principles for developing desirable fishing village models for the continued use of mudflat shells grounds as the common goods.
This study tried to examine the relationship between superior leadership and emotional support from co-workers on task performance through performance evaluation fairness and self-efficacy in order to find factors that affect the task performance of a company in an uncertain market environment. For this purpose, 500 copies of questionnaire data were collected from corporate employees, and the research hypothesis was verified using Smart PLS 3.0. As a result of the study, superior leadership and emotional support from co-workers showed a positive (+) effect individually on the fairness of employee performance evaluation, Performance evaluation fairness showed a positive (+) effect on self-efficacy. Through this study, it was found that the fairness and self-efficacy of the performance evaluation accepted by employees affects work performance, providing a theoretical foundation for subsequent researchers. Practical implications are suggested to inspire employees to take on a challenge by managing them properly. In future research, based on the results of this study, various studies are needed on the factors that an organization must have for task performance.

Objectives: To measure tympanic bone thickness (anterior-superior, anterior-inferior, and inferior wall), external ear canal length, and tympanomandibular distance that can be useful in cases that undergo tympanic bone resection. Materials and Methods: The temporal computed tomography (CT) images of 349 patients were retrospectively evaluated. The anterior-inferior, anterior-superior, and inferior wall thicknesses; tympanomandibular distance; and external auditory canal (EAC) bone canal length were measured from the narrowest part of the canal. The shapes of the EAC in the coronal and sagittal planes were also examined. Results: The numbers of female and male patients were similar, and the mean age was 49.45±13.95 years. The anterior-superior, anterior-inferior, and inferior wall thicknesses were 1.92±0.60, 2.54±0.74, and 9.16±2.20 mm, respectively. The anterior-superior and anterior-inferior wall thicknesses and canal lengths were greater on the right side (P<0.001). All measurement values were higher in males, except right tympanomandibular distance (P<0.05). A non-significant negative correlation was found between the age of the participants and the left anterior-inferior wall and tympanomandibular distance on both sides. Intra-observer agreement was high for all measurements. We observed four main shapes in the external ear canal in the coronal plane: Type 3, Type 2, Type 1, and Type 4 in order of frequency on the right, and Type 2, Type 3, Type 1, and Type 4 on the left. In the sagittal plane, we detected three shapes: oval (74.4%), triangular (16.3%), and round (9.4%). Conclusion: The anterior wall thicknesses and tympanomandibular distance should be measured on preoperative temporal bone CT to safely perform tympanic bone anterior resection, which is required in some otological procedures, and also to prevent temporomandibular joint damage.

Objectives: This study aimed to evaluate the effects on bone repair of different concentrations of mineral trioxide aggregate (MTA) added to AH Plus. Materials and Methods: Bone tissue reactions were evaluated in 30 rats (Rattus norvegicus) after 7 and 30 days. In the AH + MTA10, AH + MTA20, and AH + MTA30 groups, defects in the tibiae were filled with AH Plus with MTA in proportions of 10%, 20% and 30%, respectively; in the MTA-FILL group, MTA Fillapex was used; and in the control group, no sealer was used. The samples were histologically analyzed to assess bone union and maturation. The Kruskal-Wallis and Mann-Whitney tests were performed for multiple pairwise comparisons (p ≤ 0.05). Results: At the 7-day time point, AH + MTA10 was superior to MTA-FILL with respect to bone union, and AH + MTA20 was superior to MTA-FILL with respect to bone maturity (p < 0.05). At the 30-day time point, both the AH + MTA10 and AH + MTA20 experimental sealers were superior not only to MTA-FILL, but also to AH + MTA30 with respect to both parameters (p < 0.05). The results of the AH + MTA10 and AH + MTA20 groups were superior to those of the control group for both parameters and experimental time points (p < 0.05). Conclusions: The results suggest the potential benefit of using a combination of these materials in situations requiring bone repair.
This study was conducted to examine the superior factors and the perception of Korean traditional foods by college students studying in food related industries. The subject group consisted of 65.0% of the students majoring in food service & culinary arts, 12.9% of the students majoring in food & nutrition, and 7.3% of the students majoring in baking & pastry. The nutritional value was evaluated as the top superior factor of Korean traditional foods by the study subjects. In addition, 92.4% of reported that they had eaten Korean traditional foods in the past, 76.8% of whom responded that the reason for having Korean traditional foods was its time-honored tradition. 'Cooking for oneself' was considered to be the most popular way (78.2%) of obtaining Korean traditional foods, while the traditional market (58.6%) was the most popular place to purchase the foods. 'Not having enough time' (47.2%) was the primary reason for not having Korean traditional foods, although 72.9% of the subjects reported that they wanted to learn about Korean foods. 'Standardization of taste, nutritional value, and recipes' was found to be the most important factor (41.3%) required to increase the consumption of Korean traditional foods. Additionally, 56.1% of the subjects responded that they feel there is a need for modernization of the cuisine to meet the taste of the general public. However, 61.4% of the subjects responded that the succession of traditional dietary culture was the primary reason for developing traditional cuisine, which indicates that there is a bright future for Korean traditional foods.
