Background and Objectives : This study aimed to evaluate patients' subjective and objective outcomes after laryngeal microsurgery for benign vocal fold (VF) lesions, and to identify usefulness of surgical treatment. Materials and Methods : The authors reviewed the 102 patients medical records, retrospectively who received laryngeal microsurgery for benign VF lesions from January 2013 to August 2017. Subjective voice were measured using the Voice Handicap Index (VHI). Objective voice were recorded with Multi-Dimensional Voice Program (MDVP) just before surgery, and after at least 3 months of surgery. Results : Benign VF lesions were categorized as VF nodule (n=34, 33%), VF Polyp (n=47, 26%), Intracordal cyst (n=15, 15%), Reinke's edema (n=6, 6%), and VF Papilloma (n=2, 2%). Post-operative voice assessment at VHI scores showed statistically significant reductions in all of functional, physical and emotional parts (p<0.001). MDVP were showed significant improvement of Jitter (P=0.001), Shimmer (p<0.001) and Noise to Harmonic Ratio (NHR) (p=0.001). Conclusion : Laryngeal microsurgery for benign vocal fold lesions is effective treatment with statistically significant improvement at subjective and objective vocal quality assessment.

The purpose of this study is to propose a new design provisions for Reduced Beam Section with bolted web(RBS-B) connections for seismic applications at IMF system. Contents of study are evaluation for rotation capacity of RBS-B connections. RBS connections are newly developed connections for high ductility and energy dissipation capacity. However some experimental specimens have demonstrated that RBS-B connection was abnormally failed at the face of column and did not satisfied enough plastic rotation capacity required for that of region of high seismicity. This experimental results were considered and then RBS-B connection's application range was limited for IMF systems(ANSI/AISC 358-05). In this study, a number of parameters were considered as influences the behavior of RBS-B connection and proposed the new RBS-B design provisions for IMF system's limitation using dominated parameters at plastic capacity of RBS-B connection.

The purpose of this study is to investigate the effects of tourism marketing communication on destination brand equity of Jeju. To examine the relationship between tourism marketing communication and destination brand equity composed of brand awareness and brand image, its communication constructs are defined as advertizing, public relations and sales promotions. To verify the hypotheses, 259 valid sample data were selected from among of 260 collected by self-administrated questionnaire survey method. The analysis was performed through multiple regression and linear regression after factor analysis. Based on the analysis results, the following implications were suggested. The findings are as follows: Firstly, advertizing as tourism marketing communication influences brand awareness. Secondly, advertizing and sales promotions as tourism marketing communication influences brand image. Thirdly, brand awareness influences brand image. In conclusion, among direct influential factors of tourism marketing communication with destination brand awareness and brand image, only advertizing was in common with them both. And considering the view of IMC, we may need to use or integrate marketing communication tools strategically on the basis of this study in ordr to communicate the tourism destination with tourism consumers effictively. Several implications were presented on the basis of the research findings. Limitation and future research directions were also discussed.

Localized non-Hodgkin's lymphomas of head and neck are generally treated with radiation therapy with or without chemotherapy and the results of treatments are favorable, but the recurrences in the primary site or distant sites are a major contributor to failure, We experiened 19 cases of localized non-Hodgkin's lymphomas for 4-year period and retrogradely analized them. We treated patients with Ann Arbor stage I and low grade histology in Working formulation with radiation therapy and patients with Ann Arbor stage II, moderate to high grade histology or extensive tumor size with combination chemotherapy, The complete responses were occurred in 15 of 19 patients (radiation therapy, 5/6 (83.3%); chemotherapy 10/13(76.9%)). 3 relapses were occurred; 2 were in local relapses and 1 was in distant leptomeningeal relapse and the counter-therapeutic modalities were successful in 2 cases. Our results suggest that Ann Arbor stage is significant prognostic factor and appropriate staging with extensive methods is important to improve the results of treatment.

Objective : To obtain more reliable sample in stereotactic biopsy, authors adopted proton chemical shift imaging ($^1H$-CSI)-directed biopsy. Until now, proton single voxel spectroscopy($^1H$-SVS) technique has been reported as a technique using metabolic information in stereotactic biopsy. The authors performed $^1H$-CSI with a stereotactic headframe in place and evaluated the pathologic results obtained from local metabolic information through $^1H$-CSI. Methods : $^1H$ CSI-directed stereotactic biopsy was performed in four patients. $^1H$-CSI and conventional Gd-enhancement stereotactic MRI was done simultaneously after application of the stereotatic frame. After reconstruction of metabolic maps of NAA/Cr, Cho/Cr, and Lactate/Cr ratios, the focal areas of increased Cho/Cr ratios and decreased NAA/Cr ratios were selected for target sites in the MR images Results : There was no difficulty in performing $^1H$-CSI with the stereotactic headframe in place. In pathologic examinations, the samples taken in area of increased Cho/Cr ratios and decreased NAA/Cr ratios showed the features of increased cellularity, mitoses and cellular atypism, thus facilitated the diagnosis. The pathologic samples taken from the area of increased Lactate/Cr ratios showed prominent feature of necrosis. Conclusion : $^1H$-CSI was feasible with stereotactic head frame in place. The final pathologic results obtained in our samples were concordant with the local metabolic informations from $^1H$-CSI. Authors believe that $^1H$ CSI-directed stereotactic biopsy may provide us advantages in obtaining more reliable tissue specimen in stereotactic biopsy.
