Purpose: Although many studies have addressed destination marketing concepts, the relationship between beach tourists' memorable tourism experience (MTE), revisit intention and electronic word of mouth (eWOM) remains unknown. To address this issue, the authors established a model to investigate the effects of MTE's dimensions on revisit intention and eWOM. Research design, data and methodology: Drawing on 581 questionnaires from domestic beach tourists in Vietnam, a quantitative study approach was administered to empirically analyze a partial least squares path model in PLS-SEM. Results: The findings revealed that four dimensions of MTE including hedonism, local culture, meaningfulness and involvement have positive influence on beach tourists' revisit intention. Besides, meaningfulness and knowledge directly affect eWOM. It is worth noting that beach tourists' revisit intention significantly and directly influence their eWOM. The findings also confirm the indirect effects of hedonism, local culture, meaningfulness and involvement on eWOM through the mediating role of revisit intention. Conclusions: This study will be important to determine beach tourists' behavior through each dimension of MTE. This study also emphasizes on the direct effect of beach tourists' revisit intention on eWOM, as well as confirms its mediating role in the relation between MTE and eWOM. The findings will assist policymakers and destination marketers with strategies and effective future actions.

Purpose: This study examines short-platform content that is becoming more popular on social media. This study investigates the relationship between short-form content experience, consumer participation behavior, and consideration set. Furthermore, the mediating effect on empathy factors was confirmed during consumers' experience with short-form content. Data and methodology: Prior studies were reviewed, and hypotheses were developed. Consumers who had watched and shared short-form content within the previous three months were targeted to achieve the study's goal. A structured questionnaire was used to conduct the survey. Results: First, users of short-platform content with practical, playful, and emotional value did not confirm a positive effect on consumer participation behavior. However,short-form content with social value positively impacted consumer participation behavior. Second, consumer participation in short-form content was confirmed to positively affect the consideration set. Third, in terms of the mediating effect of empathy factors, short-platform content with practical, social, and emotional values partially mediates consumer participation behavior, whereas short-platform content with playfulness value completely mediates consumer participation behavior. Conclusions: The results of this study have academic and practical implications for the recent marketing field. In particular, research has been conducted in the field of digital marketing, which has recently changed rapidly.

Purpose : A great deal of youngsters suffer from otitis media, for which antimicrobials are frequently prescribed. Increased antimicrobial resistance forces physicians to judiciously use antimicrobial agents in treating patients with acute otitis media. There have however been few references with regard to otitis media in Korean children, and authors proceeded investigation to look for the causative agents of otitis media in Korean children and their antimicrobial susceptibility. Methods : The study included 65 patients younger than 15 years old who had been cared at the department of pediatrics and otolaryngology in Hanyang University Hospital from July 1994 to June 1999, and diagnosed of otitis media with otorrhea which contained microorganisms isolated in otorrhea culture. The medical records were reviewed for demographic data, isolated organisms and their antimicrobial susceptibility. Results : Among 65 patients, 37(57%) were boys and 28(43%) girls. Distribution of the patients was reciprocal to the age of the patients; 27 patients(41.5%) were younger than 1 year old, 24(36.9%) were 1 to 3 years old with the average of 2.9 years of age. Staphylococus aureus was isolated in 32 patients(49.2%), Streptococcus pneumoniae in 19 patients(29.2%) Haemophilus influenzae in 9 patients(13.8%), Streptococcus oralis in 3 patients(4.6%), Moraxella catarrhalis in 1 patient(1.5%). The isolated microorganisms were not different whether patients had cleft lip/palate or not. The antibiotic resistance rates of S. aureus were ${\geq}90%$ to erythromycin, imipenem, cephalothin, and clindamycin, 86.2% to oxacillin, 25% to chloramphenicol, 12.5% to trimethoprim/sulfamethoxazole(TMP/SMX), and 0% to vancomycin and teicoplanin. The antibiotic resistance rates of S. pneumoniae were 71.4% to penicillin and greater than 60% to erythromycin, tetracycline, TMP/SMX, 7.1% to chloramphenicol, and 0% to vancomycin and teicoplanin. The antibiotic resistance rates of H. influenzae were 55% to ampicillin and TMP/SMX, and 0% to chloramphenicol, ceftriaxone, aztreonam, imipenem and ciprofloxacin. Conclusion : With otorrhea culture, the causative organisms of otitis media appear to be S. aureus, S. pneumoniae and H. influenzae. The high antibiotic resistance rates of the isolated organisms should affect the choice of antibiotics in treating patients with otitis media. Prospective investigations utilizing tympanocentesis in microbiologic studies are needed.

Generally, fractured medium can be described with some key parameters, such as hydraulic conductivities or random field of hydraulic conductivities (continuum model), spatial and statistical distribution of permeable fractures (discrete fracture network model). Investigating the practical applicability of the well-known conceptual models for the description of groundwater flow in fractured media, various types of hydraulic tests were applied to studies on the highly fractured media in Geumsan, Korea. Results from single-hole packer test show that the horizontal hydraulic conductivities in the permeable media are between $7.67{\times}10^{-10}{\sim}3.16{\times}10^{-6}$ m/sec, with $7.70{\times}10^{-7}$ m/sec arithmetic mean and $2.16{\times}10^{-7}$ m/sec geometric mean. Total number of test interval is 110 at 8 holes. The number of completely impermeable interval is 9, and the low permeable interval - below $1.0{\times}10^{-8}$ m/sec is 14. In other words, most of test intervals are permeable. The vertical distribution of hydraulic conductivities shows apparently the good correlation with the results of flowmeter test. But the results from the cross-hole test show some different features. The results from the cross-hole test are highly related to the connectivity and/or the binary properties of fractured media; permeable and impermeable. From the viewpoint of the connection, the application of the general stochastic approach with a single continuum model may not be appropriate even in the moderately or highly permeable fractured medium. Then, further studies on the investigation method and the analysis procedures should be required for the reasonable and practical design of the conceptual model, with which the binary properties, including permeable/impermeable features, can be described.

Methods of contrast enhancement have problem such as side effect of over-enhancement with non-gaussian histogram distribution, tradeoff enhancement efficiency against brightness preserving. In order to enhance contrast at various histogram distribution, segmentation to region with gaussian distribution and then enhance contrast each region. First, we segment an image into several regions using GMM(Gaussian Mixture Model)fitting by that k-mean clustering and EM(Expectation-Maximization) in $L^*a^*b^*$ color space. As a result region segmentation, we get the region map and probability map. Then we apply local contrast enhancement algorithm that mean shift to minimum overlapping of each region and preserve brightness histogram equalization. Experiment result show that proposed region based contrast enhancement method compare to the conventional method as AMBE(AbsoluteMean Brightness Error) and AE(Average Entropy), brightness is maintained and represented detail information.

To evaluate a property of moisture distribution and volumetric water content on bentonite media the responses of complex dielectric constant were used which are measured by Frequency Domain Reflectometry with Vector Network Analyzer (FDR-V) system. The bentonite is widely used a barrier liner system in the waste disposal site, recently. In case of barrier liner system, generally, the coefficient of permeability should have to less than 10-7cm/sec. According to the results, the complex dielectric constants are increasing with increase the volumetric water content and temperature together. Also the variation of complex dielectric constant due to temperature gradient is confirmed that the moisture movements are increasing with the variations of temperature from high range to low range, which is represented the property of moisture distribution in the bentonite.

Nowadays the soccer becomes one of the best spot lighting sports in the world Especially the 2002 Korea-Japan World Cup was deeply impressed on all the korean. One goal of illuminating engineering should be the design of lighting system that can provide consistently high task visibility regardless of where a task might be located within a working space. The television broadcasting on the soccer has been an important role in the media. The standard of FIFA(The Federation Internationale do Football Association) requires recommended illuminance levels for artificial lighting for a player, an audience, TV broadcasting, as well as everybody in the stadium. This paper has proposed an algerian to select the suboptimal lighting tower position for watching and TV broadcasting a soccer game within a pleasant environment and an optimum illuminance distribution. The position using the software Philip's Calculux was chosen based an the calculations of a horizontal illuminance, vertical illuminance, uniformity, glare, and so on by changing lighting tower positions.

Beryllium (Be), cobalt (Co), thallium (Tl) and vanadium (V) are candidates of 21 priority soil pollutants in Korea. The distribution of their concentration in soils from three contamination sources including industrial, roadside and mining areas was investigated. Concentrations of the metals were evaluated quantitatively using pollution indices and the fractionation of metals was conducted using modified SM&T (Standards Measurements and Testing programme) sequential extraction. Concentrations of the metals for all samples from industrial and roadside soils were within the range of natural background levels, while some of Be in soils from abandoned mines exceeded that the range. Enrichment Factor (EF) and Nemerow Integrated Pollution Index (NIPI) for Be, Co, Tl and V showed that there are effects or possibilities of anthropogenic activities. Pollution Load Index (PLI) analyses indicated all investigated sites needed further monitoring. The results of sequential extractions indicated mobile fractions (F1+F2) of Be, Tl and V were below 30% except some of Co in soil, which implies their low mobility to neighboring environment media. Variable tools like sequential extraction, comparison with background/actual concentration and pollution indices, as well as aqua regia extraction should be considered when evaluating Be, Co, Tl, V in soil.
