Yhang, Wii-Joo Korean Institute of Navigation and Port Research 2004 한국항해항만학회지 Vol.28 No.4

The competitiveness of a country or a city plays an important role as a determining factor in this age of globalization In view of tourism studies, the potential for a region to develop depends primarily on its ability to use and maintain economic advantages in its provision of tourist products and services. In spite of the importance of competitiveness in tourism studies, few researches have been done on competitiveness in Korea The purpose of this study is, therefore, to conduct a comparative analysis of competitiveness between coastal metropolitan cities in Korea-Busan, Ulsan and Incheon- developing tourism index and finding out urban competitiveness. The findings of this study will contribute to enhancing tourism promotion and mutual network with other cities and attracting domestic and international tourists.

이 연구의 주요목적은 GIS 프로그램 (MIPS)을 이용하여 콤퓨터 이미지 처리와 이미지 분석을 응용하는 것이다. 이러한 과학적 기술은 눈에는 보이지만 해독할 수 없는 정보를 발견하며 그 인과관계를 밝혀내는 데 크게 도움을 준다. 본 연구는 실제 자연환경을 담고있는 사진으로부터 색채분석에 응용시켜 보려하였다 각각의 사진은 8 종류의 색채로 나누어졌다 어두운 붉은 색과 밝은 빨강색, 어두운 푸른색과 밝은 푸른색, 어두운 녹색과 밝은 녹색, 검정색, 횐색. The main objective of this study applies the computer technology of image processing and image analysis to the analysis of color composition using GIS (Geographic Information System) program, MIPS. The scientific technique helps greatly to discover visible but illegible information and then to investigate the cause and effect. Here this method could be used in analyzing photographs taken from the real natural environment. Raw data is collected in a systematic way with minimum amount of time and budget. color composition of each photograph will be broken down to 8 colors: dark red, dark green, dark blue, light red, tight green, light blue, black, and white.

조사방법을 실행함에 있어 표본추출과정에 대한 기본적인 지식은 표본인구와 표본 틀의 본질을 이해하는데 필요하다. 특히, 표본설계단계 다음 절차인 자료수집과정은 전화나 우편조사 또는 개별면담처럼 현장이나 실내에서 실시되는 장소성을 수반하고 있음을 주목한다. 이러한 환경적 요인은 표본 선택의 정확성이나 조사자의 훈련정도 또는 현장에 파견된 조사참여진의 통제 등에 관한 기초적 의문을 야기시킨다. 본 연구는 조사방법에 대한 연구수행이 출발점부터 잘못되어질 수 있다는 관점에서 위에 열거한 문제 등을 검토해 보면, 특히 오류의 원천(sources of erros)에 그 역점을 두기로 한다. 자료수집과정에서 발생되는 다양한 오류의 원천에 관한 정확한 이해는 잠재적 문제에 대한 통찰력을 제공하며, 진행되는 연구에 사용된 정보를 분석·평가하는데 도움을 준다. 모든 종류의 조사방법이 어떠한 형태의 오류에 필연적으로 종속되어져 있지는 않지만, 비표본 추출 오류(nonsampling error)와 조사방법 결과시 그 영향을 정확히 인식하기 위해서는 연구자가 다양한 형태의 오류를 숙지할 필요가 있으며, 연구결과를 보고함에 있어 비표본추출 오류에 관한 정보의 제시에 그 당위성을 부과하고자 한다.

A Novel Mediastinal Drainage Tube for Mediastinitis

Yhang, Jun Ho,Jang, In-Seok,Kim, Sung Hwan,Park, Hyun Oh,Kang, Dong Hoon,Choi, Jun Young The Korean Society for Thoracic and Cardiovascular 2015 Journal of Chest Surgery (J Chest Surg) Vol.48 No.5

Mediastinitis is a life-threatening disease, and effective drainage is needed to treat mediastinitis with abscess formation. We recommend an alternative drainage method using chest tube binding with a Silastic Penrose drainage tube. The use of a Silastic Penrose drainage tube may help to manage mediastinitis with abscess formation. This method facilitates effective draining and prevents tissue adhesion.

Application of Dynamical and Statistical Downscaling to East Asian Summer Precipitation for Finely Resolved Datasets

Yhang, Yoo-Bin,Sohn, Soo-Jin,Jung, Il-Won Hindawi Limited 2017 Advances in meteorology Vol.2017 No.-

<P>Various downscaling approaches have been developed to overcome the limitation of the coarse spatial resolution of general circulation models (GCMs). Such techniques can be grouped into two approaches of dynamical and statistical downscaling. In this study, we investigated the performances of different downscaling methods, focusing on East Asian summer monsoon precipitation to obtain more finely resolved and value added datasets. The dynamical downscaling was conducted by the Regional Model Program (RMP) of the Global/Regional Integrated Model system (GRIMs), while the statistical downscaling was performed through coupled pattern-based simple linear regression. The dynamical downscaling resulted in a better representation of the spatial distribution and long-term trend than the GCM produced; however, it tended to overestimate precipitation over East Asia. In contrast, the application of the statistical downscaling resulted in a bias in the amount of precipitation, due to low variance that is inherent in regression-based downscaling. A combination of dynamical and statistical downscaling produced the best results in time and space. This study provides a guideline for determining the most effective and robust downscaling method in the hydrometeorological applications, which are quite sensitive to the accuracy of downscaled precipitation.</P>

Marine Tourism Development Strategy of the South Sea through Sustainable Management of Coastal Environment

Yhang, Wii-Joo Korean Institute of Navigation and Port Research 2006 한국항해항만학회지 Vol.30 No.4

This study is to integratedly examine coastal management policy and marine tourism development project for Korean coasts, especially for the South Sea of high development pressure, presenting sustainable tourism development policies for the future. To do so, it is examined central government-level coastal development projects set up by the Ministry of Culture and Tourism, the Ministry of Maritime Affairs and Fisheries and the Ministry cf Construction and Transportation, setting the direction of south coastal management and tourism development at a level of national territory planning. The problems of coastal management first and then the problems of the South Coast Tourism Belt Project are analyzed in order to present political and administrative alternatives. To overcome such problems and make Korea a marine tourism base in East Asia, there is a need for re-recognition of the value of the project and its continuous push through cooperation between central and local governments. Also, under the presupposition of consensus building among local people and the sustainable development of environments, there should be are-recognition that the future cf Korean marine tourism in the 21st-century and the success of an inverted $\pi-axis$ national development depend on the South coastal Tourism Belt Development Project.

Evaluation of Busan Marine Tourism Cluster by the Concordance Test

Yhang, Wii-Joo,Lee, Sang-Ho,Jun, Jae-Kyun Korean Institute of Navigation and Port Research 2007 한국항해항만학회지 Vol.31 No.7

By employing primarily the Kendall's Concordance Test, the paper attempted to conduct an experts' evaluation on the interaction among the agents in Busan marine tourism cluster and recommend some measures for policy consideration for the cluster's activation. For this purpose, a conceptual framework was developed to guide the assessment by using inter-agent cooperation and network approaches regarding the nature of the marine tourism cluster. Such factors as cooperation, competition, relationship marketing, and networking were identified as critical. Findings of the study imply that Busan marine tourism cluster is at its embryonic stage and needs desperate measures for improvement in the inter-organizational cooperation and networking, the major regional characteristics that determine the competitiveness of marine tourism.

Relationship between Image-processed Color Content and Human Color Visibility Estimation of Natural Forest Scenes

Yhang, Wii-Joo The Korean Environmental Sciences Society 2002 한국환경과학회지 Vol.11 No.8

The current study investigated the relationship between image processed data and human visibility data for natural forest scenes from the perspective of color. In particular, the results indicated relatively low Pearson product-moment correlations between the color ratings obtained from the two methods used in the study. The first method measured the color content of slides using a image processing program, while the second used a panel of human judges to rate the color content of each slide.
