When we consider to develop a new harbor, the most important factor, we think, is the lowest water depth of waterway and approaching channel for safe navigation of vessel. The existing harbors have been being dredged to meet the international trend of jumbo sized vessels by adopting the new design criteria. As the dredged materials over the expected at the design level were common and there are still lack of land based reclamation area, we have no choice to discharge the dredged materials in open sea area In this study, we analysed the behavior of discharged materials at the dumping area of offshore, which were collected from the dredging work at the waterway in Busan New Port. We measured the tidal currents and analyzed the waters of dumping site after the dumping work. These were used to evaluate the numerical models. Suspended Solids(SS) were introduced to the diffusion model. Because of the characteristic of the dumping site, the speed of initial diffusion and settle down of the discharged materials was so fast. Therefore, we believe that the dumped materials do not cause a significant impact to the marine environment.

Globus pharyngeus is a common problem comprising between 3% and 4% of new otolaryngology outpatient referrals. We do not understand the etiology of globus exactly and it is remained a disease of exclusion. The treatment of globus pharyngeus is still not established. The aim of this study is to understand the etiologic factors and determine the reliable guide for selecting method of choice of evaluation and improving therapeutic response of globus pharyngeus. A total of 141 patients were investigated by authors. 25 of 141 patients were excluded from the study because they could not satisfy the definition criteria of this study. After detailed Interview and comprehensive physical examinations, all the 116 patients had underwent barium esophagogram, fiberoptic esophagogastroscopy, esophageal manometry and 24-hour pH monitoring. They could follow up for at least 3 months. There were 43 male and 73 female subjects and the mean age was 46.5 year. Esophagogram revealed normal in 94(81%) subjects. 78 patients(67.2%) were normal in esophageal manometry. Gastroesophageal reflux(GERD) was found in 24 cases and borderline GERD was found in 25 cases showing an overall incidence of 42.2% for 24-hour pH monitoring. Especially 44(89.8%) of the 49 patients with proven reflux on 24-hour pH monitoring showed therapeutic response whereas 48(71.6%) of the 67 subjects without reflux showed response.

The purpose of this study was to examine clothing purchase behavior of sports participants based on outdoor sports types and sports participation motivation. The research was conducted with the use of a self-administered questionnaire. A total of 703 respondents between the ages of 25 and 55 participated in the research through an internet survey. Motivation for participation in particular sports was comprised of four factors: impress others, mental rejuvenation, social interaction, and health maintenance/improvement. Perceived benefits of clothing choice were categorized into three factors: brand/fashion pursuit, positive image pursuit, and practicality pursuit. Outdoor sports activities was categorized into six types, climbing, jogging, cycling, fishing, golf, and others including ball games. Each sports group presented differences in demographics, sports motivation factors, and benefit factors. Four segments were identified based on sports participation motivation: active group, social group, health and revitalization group, and inactive group. The active group considered three clothing benefits and 14 evaluative criteria as being the most important among the four segments, indicating the major target market for outdoor sportswear brands. On the other hand, the members of inactive group showed passive attitudes toward clothing purchasing behaviors. This study discusses the results of this research within the context of the managerial implication for outdoor sports marketers.

The use of fiber reinforced polymer (FRP) composites in strengthening reinforced concrete beam-column subassemblies has been scrutinised both experimentally and numerically in recent years. While a multitude of numerical models are available, and many match the experimental results reasonably well, there are not many studies that have looked at the efficiency of different finite elements in a comparative way in order to clearly identify the best practice when it comes to modelling FRP for strengthening. The present study aims at investigating this within the context of FRP retrofitted reinforced concrete beam-column subassemblies. Two programs are used side by side; ANSYS and VecTor2. Results of the finite element modeling using these two programs are compared with a recent experimental study. Different failure and yield criteria along with different element types are implemented and a useful technique, which can reduce the number of elements considerably, is successfully employed for modeling planar structures subjected to in-plane loading in ANSYS. Comparison of the results shows that there is good agreement between ANSYS and VecTor2 results in monotonic loading. However, unlike VecTor2 program, implicit version of ANSYS program is not able to properly model the cyclic behavior of the modeled subassemblies. The paper will be useful to those who wish to study FRP strengthening applications numerically as it provides an insight into the choice of the elements and the methods of modeling to achieve desired accuracy and numerical stability, a matter not so clearly explored in the past in any of the published literature.

Let G be a complex semisimple simply connected linear algebraic group. The main result of this note is to give several equivalent criteria for the untwistedness of the twisted cubes introduced by Grossberg and Karshon. In certain cases arising from representation theory, Grossberg and Karshon obtained a Demazure-type character formula for irreducible G-representations as a sum over lattice points (counted with sign according to a density function) of these twisted cubes. A twisted cube is untwisted when it is a "true" (i.e., closed, convex) polytope; in this case, Grossberg and Karshon's character formula becomes a purely positive formula with no multiplicities, i.e., each lattice point appears precisely once in the formula, with coefficient +1. One of our equivalent conditions for untwistedness is that a certain divisor on the special fiber of a toric degeneration of a Bott-Samelson variety, as constructed by Pasquier, is basepoint-free. We also show that the strict positivity of some of the defining constants for the twisted cube, together with convexity (of its support), is enough to guarantee untwistedness. Finally, in the special case when the twisted cube arises from the representation-theoretic data of $\lambda$ an integral weight and $\underline{w}$ a choice of word decomposition of a Weyl group element, we give two simple necessary conditions for untwistedness which is stated in terms of $\lambda$ and $\underline{w}$.

The purpose of this study was to provide information for the manufacturers of shoes for males to develop more adequate footwear. The data was collected through a questionnaire on purchasing and wearing practices of footwear, and overall satisfaction with the shoes for males. The questionnaire survey was conducted on 237 male adults in the Cheongju area. Most of the respondents were commuting by their own cars and the average walking time in their shoes was five minutes per day. The main reasons for buying new footwear were to replace the worn out footwear or to adapt the color and design coordination with other apparel. Males generally bought footwear from sports brand retailers and individual footwear stores. The criteria for purchasing in order of considered were size, design, price, comfort, and style coordination. During the spring, autumn and winter seasons, the footwear of first choice was ordinary shoes, followed by exercise shoes, but during the summer season they wore sandals next to the ordinary shoes. Regarding the form of the shoes, they preferred classic models with round front and strings. They were satisfied with the design, color and size of the shoes, but the price, quality and durability of the material were considered to be unsatisfactory.

This article discusses the findings of an empirical study conducted on 62 large organizations. The major purpose of the study was to analyze the relationship of Information System Resources distribution between the system plan control and system development and system operation. In this study information system resource is broadly Identified by computer hardware, software, data, procedure, operator. Because of the real centralization/decentralization issue facing organizations is much broader then the choice between alternative computer hardware configurations. And there are three separate resources of the information system that can be decentralized system plan and control, system development, system operations. The decision regarding how to organize each of these three separate resources is based on a different set of criteria. Furthermore, each decision can be made relatively independently of the others. In this article the results of a study are indicated below. In the degree of decentralization of information system resources between system plan control and system development and system operations were found the positive relationship. Therefore, the more information system resources are decentralized in the one dimension, the more information system resources are decentralized in the other dimensions, and the more information system resources are centralized in the one dimension, the more information system resources are centralized in the other dimensions.

We demonstrate the luminosity dependence of the covering factor (CF) of active galactic nuclei (AGNs), based on AKARI mid-infrared all-sky survey catalog. Combining the AKARI with Sloan Digital Sky Survey (SDSS) spectroscopic data, we selected 243 galaxies at $9{\mu}m$ and 255 galaxies at $18{\mu}m$. We then identified 64 AGNs at $9{\mu}m$ and 105 AGNs at $18{\mu}m$ by their optical emission lines. Following that, we estimated the CF as the fraction of type 2 AGN in all AGNs. We found that the CF decreased with increasing $18{\mu}m$ luminosity, regardless of the choice of type 2 AGN classification criteria.
