오세아니아지역 환경친화적 관광프로그램에 관한 연구

최재우 경북대학교 사회과학대학 지리학과 2006 地理學論究 Vol.- No.25

세계경제 내에서 가장 급속하게 성장하는 관광은 이미 대부분의 국가에서 잘 정착되고 있다. 본 연구는 해외지역연구로서 오세아니아지역의 환경친화적 관광프로그램의 특성에 대해 탐구한 것이다. 본 연구의 목적을 달성하기 위해서 관련 문헌조사 후 오세아니아지역(호주, 뉴질랜드, 피지)을 방문하였다. 연구사례지역은 뉴질랜드의 Waitomo 반딧불이 동굴, 뉴질랜드의 Waipoua Kauri 삼림지대, 호주 빅토리아주 Phillip 섬, 피지 Nadi 부근 Nalesutale 피지원주민마을 등이다. 생태관광프로그램의 대부분은 환경적, 경제적 및 교육적 효과를 위해 개발되었다. 오세아니아지역의 사례연구들은 한국에서 생태관광과 환경보전이 성공할 수 있는 좋은 모델을 보여주고 있으며, 한국에서 환경친화적 관광산업을 위한 효과적인 지역정책들을 제공할 수 있을 것이다. Tourism, the fastest growing industry within the global economy, is already well established within most countries. This paper aims to explore the characteristics of the environmental friendly tourism programs in Oceanian area as a foreign area study. To achieve the objectives, this research carried out a literature review before taking several field surveys in Oceania area(Australia, New Zealand, and Fiji). Research areas are Waitomo Glow Warm Caves in New Zealand, Waipoua Kauri Forest in New Zealand, Phillip Island in Australia, Nalesutale Fijian indigenous village in Fiji Islands. Most of all ecotour programs are developed for environmental, economical and educational effects. The case studies of Oceania area present a good model of how to succeed in ecotourism and conservation management to Korea. In addition, this research will provide effective regional policies for the environmentally friendly tourism in Korea.

3차 칼라 오브젝트 관계에 의한 내용 기반 영상 검색

본 논문은 정지 화상에 대한 CBIR(Content-Based Image Retrieval)방법 중 칼라 특성을 이용해서 영상 내 공간 정보를 충분하게 표현할 수 있는 알고리즘을 제안한다. 일반적으로 칼라 특성을 이용한 CBIR은 영상 내 공간정보를 충분하게 표현하지 못하는 단점을 지니고 있다. 이에 기존 논문에서는 인위적으로 영상을 여러 개로 분할하는 방법 등으로 공간정보를 표현하고자 하였지만 특징백터의 수가 급격히 늘어남에 따라 검색효율이 저하된다는 단점을 가지고 있다. 본 논문에서는 기존의 방법을 칼라오브젝트의 추출 방법에 따라 1차와 2차 관계에 의한 방법으로 분류하고, 이동, 회전 특히 크기 변화(축소, 확대)에 탁월한 성능을 보이는 칼라 오브젝트의 3차 관계를 이용한 방법을 소개한다. 주어진 영상으로부터 양자화된 24개의 버킷을 생성해서 각 버킷 내의 칼라에 대한 색의 표준 편차로 색의 분산 정도를 나타내고, 히스토그램의 빈도수가 높은 세 개 버킷의 평균 칼라 위치를 계산해서 그들의 상호 각도를 추출하여 영상의 특징 벡터로 사용한을 제안하였다. 실험결과 기존 방법보다 특히 영상의 크기 변화에 대해 좋은 결과를 얻을 수 있었으며, 계산량도 적어 효율적임을 보여 주었다.

근로자의 고용상태가 미충족 의료에 미치는 영향

최재우 보건의료산업학회 2018 보건의료산업학회지 Vol.12 No.4

Objectives: This study was designed to evaluate whether employment status is associated with the experience of unmet care needs. Methods: This study utilized the Korea Health Panel data from 2012 to 2016. A total of 4,083 workers were selected as baseline subjects in 2012 and were followed for four years. This study used the GLIMMIX procedure under the marginal model while adjusting for covariates. Results: A total of 12.4% of 4,083 people said they had failed at least once to have a treatment or checkup despite the needs. Those more likely to experience unmet care needs were women and people of lower income level, with worse health conditions and chronic disease. Precarious workers, the self-employed, and the unemployed were more likely to experience unmet care needs caused by economic burden than permanent workers (Odds Ratio: 2.14, 2.07, 2.74, respectively). Conclusions: This disparity means that precarious workers and the unemployed are more likely to face barriers in obtaining needed health services. Given their insecure employment status, meeting their needs for health care is an important consideration.

The Ability of the Acute Physiology and Chronic Health Evaluation (APACHE) IV Score to Predict Mortality in a Single Tertiary Hospital

Background: The Acute Physiology and Chronic Health Evaluation (APACHE) II model has been widely used in Korea. However, there have been few studies on the APACHE IV model in Korean intensive care units (ICUs). The aim of this study was to compare the ability of APACHE IV and APACHE II in predicting hospital mortality, and to investigate the ability of APACHE IV as a critical care triage criterion. Methods: The study was designed as a prospective cohort study. Measurements of discrimination and calibration were performed using the area under the receiver operating characteristic curve (AUROC) and the Hosmer-Lemeshow goodness-of-fit test respectively. We also calculated the standardized mortality ratio (SMR). Results: The APACHE IV score, the Charlson Comorbidity index (CCI) score, acute respiratory distress syndrome, and unplanned ICU admissions were independently associated with hospital mortality. The calibration, discrimination, and SMR of APACHE IV were good (H = 7.67, P = 0.465; C = 3.42, P = 0.905; AUROC = 0.759; SMR = 1.00). However, the explanatory power of an APACHE IV score >93 alone on hospital mortality was low at 44.1%. The explanatory power was increased to 53.8% when the hospital mortality was predicted using a model that considers APACHE IV >93 scores, medical admission, and risk factors for CCI >3 coincidentally. However, the discriminative ability of the prediction model was unsatisfactory (C index <0.70). Conclusions: The APACHE IV presented good discrimination, calibration, and SMR for hospital mortality.

관광자 가치에 따른 스마트폰 관광정보활용이 관광자의 제약요인 해소에 미치는 영향

최재우,김정준,오경택 관광경영학회 2015 관광경영연구 Vol.65 No.-

This study was conducted to study how the use of tourism information on the Smartphone contributes to resolving tourists' restriction factors according to the values pursued by each individual tourist. A total of 374 samples were extracted among the tourists who used the tourist information acquired from the Smartphone and the following are the results of analysis using SPSS 18.0. First, the tourists who pursue emotional values perceived the polarity and usability of tourist information on the Smartphone. Second, the tourists who pursue social values perceived the reliability and interactivity of tourist information on the Smartphone. Third, the polarity of use of tourist information on the Smartphone had a significant influence on intrinsic restriction and face-to-face interactivity restriction, while interactivity had a significant influence on face-to-face interactivity restriction and usability had a significant influence on intrinsic restriction and structural restriction. Finally, the reliability of tourist information on the Smartphone rather increased the tourists' perception of intrinsic restriction. Future studies could be improved by verifying the influence of tourist information on the Smartphone on the actual behaviors and attitudes of tourists.

Sorption kinetics of aqueous benzene for attached bacteria on sorbents?

최재우,최낙철,Basuvaraj Mahendran,김동주,이철의 한국물리학회 2007 Current Applied Physics Vol.7 No.1

In this study we investigated the eect of bacteria attached onto the surfaces of two sorbents e.g., activated carbon and alginate bead,on the sorption kinetics of aqueous benzene. Kinetic sorption experiments were performed to obtain time-dependent data of aqueousconcentration subjected to sorption at an initial concentration. The kinetic sorption data were tted with two-site sorption model thatshowed that both fast sorption and biodegradation was associated with removal of benzene for alginate bead, but only fast sorptionfor activated carbon for either case of bacterial treatment. Much lower sorption for attached case of carbon can be explained by the factthat bacteria inhibited sorption of aqueous benzene by lling them in the cavities of carbon surface. Modeling study revealed that sorp-tion process for activated carbon followed two-site kinetic with unlimited slow sorption but the one for bead was described by two-siteing capacity.
