As new players emerge, using technology and the global reach of the Internet and social media to reach out to a discerning group of travelers, they speak to the changing expectations and behavior of international consumers. Our study will shed light on these consumption and travel patterns, on ways new disruptors in the field of luxury hospitality successfully differentiate themselves from their more traditional competitors and on the implications this will have on the business models of five-star hotels in Switzerland. While limited in scope, this study will provide insight relevant to academics and professionals in the field of luxury hospitality.

항공기 충돌사고는 1970년대부터 원자력발전소의 인허가에 중요하게 고려되어 온 외부 사건의 하나였다. 9.11 테러 이후 세계 각국에서는 사고로 인한 항공기 충돌에 더하여 의도된 항공기 충돌에 대비한 안전성 평가를 수행해오고 있으며 일부 국가에서는 이를 법제화하여 인허가의 중요한 요건으로 다루고 있다. 항공기 충돌에 대한 안전성 평가는 여러가지 요인으로 인하여 쉽지 않은 작업이며 보다 신뢰성 있는 평가를 위한 연구개발이 세계 각국에서 진행 중이다. 본 논문에서는 각국의 항공기 충돌에 대비한 안전성 평가 요건의 법제화 현황을 사고로 인한 충돌과 의도된 충돌의 경우로 분리하여 정리하였다. 다 양한 조건의 항공기 충돌에 대한 안전성 평가를 위하여 수행되어 온 연구 중 주요한 것들을 정리하였으며 특히 사용후핵연 료 건식저장시설에 대한 내용을 위주로 다루었다.

국내 고준위 방사성폐기물 심층처분시스템에 대한 프로세스 기반의 종합성능평가체계(APro) 개발을 위하여 사용자 편의성이 향상된 모델링 인터페이스를 구축하였다. APro의 모델링 인터페이스는 프로그래밍 언어인 MATLAB을 이용하여 구축되었고, 다중물리현상 모사가 가능한 COMSOL과 지화학반응 계산이 가능한 PHREEQC를 계산 엔진으로 활용하여 연산 자분리 방식을 적용하였다. APro는 모델링 영역을 기존의 정형화된 처분시스템으로 제한함으로써 모델의 자유도는 낮지만, 사용자 편의성을 향상시켰다. 처분시스템에서 고려되는 주요 현상들을 모듈화하였고, 이를“Default process”와 다수의“Alternative process”로 구분하여 사용자가 선택할 수 있도록 함으로써 모델의 유연성을 높였다. APro는 크게 입력자료 부분과 계산실행 부분으로 구성된다. 기본 입력자료는 하나의 EXCEL 파일에 일정한 포맷으로 정리되고, 계산실행 부분은 MATLAB을 이용하여 코딩되었다. 최종적인 전체 계산 결과는 독립적인 COMSOL 파일 형태로 생성되도록 하여 COMSOL을 이용한 계산 결과의 후처리가 가능하도록 하였다.

In spite of the benefits of English oral presentations on EFL learners' proficiency and competence, English presentations have not obtained much attention as instructional medium in the field of English education. With the belief that EFL learners' experience of English presentation performance can provide valuable insights for educators and researchers, this study intended to describe how EFL learners perceive their presentation performance through their reflective self-assessment. In particular, adopting Otoshi and Heffernen's (2008) rubric of evaluation, this study examined what a group of Korean EFL learners were concerned in regard to their presentation performances and how they evaluated them. The data collected were 41 reflective self-assessment papers written by 41 Korean college students. The papers were coded, categorized and interpreted. Findings showed that voice quality is the area the students in this paper were most concerned about. Negative evaluations of their presentation performance outweighed the positive evaluations except in the area of Power Point use. Lastly, rehearsal and visual aids education sessions as well as differentiating spoken and written English were suggested as instruction implications for educators.

본 연구에서는 광주광역시 학교급식 농산물의 잔류농약을 모니터링하고 섭취량에 따른 위해평가를 실시하였다. 2015년부터 2017년 까지 광주광역시 소재 학교에 공급되는 농산물 320건을 실험대상으로 하였다. 농산물 전처리 및 잔류농약 분석은 식품공전 다종 농약 다성분 분석 제2법에 따라 120종의 잔류농약을 실험하였다. 검량선에 대한 직선성 상관계수는 0.9923~1.0000, LOD는 0.004~0.019 mg/kg, LOQ는 0.012~0.057 mg/kg으로 양호하게 나타났으며 회수율은 79.1~100.2%로 나타났다. 학교급식에 사용되는 농산물 320건 중 18건(5.6%)에서 잔류농약이 검출되었으며, 고구마 순 1건(0.3%)이 잔류농약허용기준을 초과하였다. 잔 류농약 검출빈도는 고추 8회, 파프리카 3회로 다른 농산물에 비해 높은 검출빈도를 나타내었고 가장 높은 검출빈도를 나타낸 잔류농약은 boscalid(4회)와 acetamiprid(3회)로 나타났다. 실험결과 학교급식 농산물 중 고추, 파프리카, 고구마 순에 대한 잔류농약 관리가 필요한 것으로 나타났다. 잔류농약 위해도 평가 결과 고구마 순에서 검출된 bifenthrin이 64.18%로 가장 높았으며, 고추에서 검출된 boscalid 등의 Hazard index는 0.03~8.23%로 나타나 학교 급식 농산물의 Hazard index는 안전한 수준으로 평가되었다. 그러나 채소류를 학교급식 식재료로 제공할 경우 잔류농약 식이섭취량을 최소화하기 위해 철저한 세척이 필요한 것으로 판단되며 친환경 농산물의 식재료 보급 확대가 필요한 것으로 판단된다.

수생태계 생물학적 온전성을 평가하기 위하여 국내 하천 및 하구 923개 지점의 자료를 근거로 한국형 다중형 돌말지수 (KMDI)를 개발하고, 이를 금강수계 233개 지점을 대상으로 온전성평가를 실시하여 단일형 돌말지수들과 비교 검토하였다. KMDI의 개발은 1) 먼저 선행문헌들을 참고로 300개 이상의 메트릭을 추출하고, 2) 이 중 설명력이 높은 46개 후보 메트릭을 선택하며, 3) 각 메트릭 값들의 변이성, 중복성, 변별력, 환경에 대한 민감성 등을 검증하고, 최종적으로 5가지의 메트릭을 선정하였다. KMDI는 매트릭의 단순합으로 표현하고, 환경요인들에 대한 신뢰성 검토 결과, 토지이용, BOD, TN, 전기전도도 등에 대해 높은 민감성 및 설명력을 보였으나 단일형 돌말지수들 보다는 동일 지점의 생물학적 온전성은 다소 높게 평가되는 특성을 보였다. 추후 국내는 물론 지역에 상관없이 적용가능한 설명력 높은 매트릭의 발굴 및 정확한 돌말류 분석 연구가 뒷따라야 될 것으로 판단되었다.

Le but de cette étude est de suggérer un échantillon d’ensembles d’outils de test pour évaluer l’évaluation basée sur les performances des tâches dans l’enseignement intégratif de la langue et de la culture françaises.

A two-year study was conducted from 2017 to 2018 by the establishment of a test field at Chungju-si and Cheongyang-gun. Plant height, number of leaves, insects and diseases, and fresh and dry matter yields for corn hybrid(‘Kwangpyeongok’) were investigated. Daily average, maximum, and minimum temperature, monthly average temperature, daily precipitation, and sunshine duration during the growing season were investigated. We selected climate-critical factors to corn productivity and conducted an evaluation of vulnerability to climate change from 1999 to 2018 for both regions. In 2018, the dry matter yield of forage corn was 6,475 and 7,511 kg/ha in Chungju and Cheongyang, respectively, which was half of that in 2017. The high temperature and drought phenomenon in the 2018 summer caused the corn yield to be low. As well as temperature, precipitation is an important climatic factor in corn production. As a result of climate impact vulnerability assessment, the vulnerability has increased recently compared to the past. It is anticipated that if the high temperature phenomenon and drought caused by climate change continues, a damage in corn production will occur.

This study investigated the structural and functional differences between formulaic sequences in College Scholastic Ability Test (CSAT) and SAT reading assessment texts. The results of the RANGE program showed that SAT used more diverse and difficult words compared to CSAT. The frequency analysis revealed that CSAT used more formulaic sequences than the SAT counterpart. This suggests that CSAT used more repeated expressions, whereas SAT used diverse vocabulary items. The structural analysis showed that noun phrases were the most dominant in CSAT, whereas prepositional phrases were pervasive in SAT. The functional analysis showed that both corpora relied heavily on referential expressions. The results indicate that referential bundles are dominantly used in institutional writing (Biber & Barbieri, 2007). In accordance with the previous studies, the results suggest that high frequency formulaic sequences can be different according to the register. In CSAT, connectives and discourse organizers were prevalent. This may be due to the characteristics of question types in CSAT. The results may indicate that formulaic sequences in texts are partly influenced by the characteristics of a register.

The demand for the revitalization of marine tourism in Busan North Port is increasing due to changes in functions such as an increase in harbor traffic volume and the expansion of marine leisure space in Busan. As a result, Busan City plans to set a phased alleviation target for prohibition of cruise ship operations, and to lift the prohibition of excursion ship operations in North Port following the cancellation of the prohibition of excursion ship operations in South Port in 2017. The purpose of this study is to evaluate the risk of excursion ship operations in Busan North Port by applying the marine traffic assessment index and to examine the possibility of excursion ship operations. For this purpose, port status, marine accidents, and traffic flow of Busan North Port were investigated. In addition, marine traffic assessment indexes, such as traffic congestion, risk based on an ES Model, and IWRAP MkII, a maritime risk assessment tool, were used to assess the risk and possibility of excursion ship operations in Busan North Port. This study can be used as basic data for analyzing the risk factors that may occur when excursion ships are operated in Busan North Port and to define how excursion ships should operate, with related safety measures.

The recent increase in crude oil trading has led to an increase in the workings of SPM for crude oil carriers. VLCCs generally encounter difficulty entering port due to limitations in terms of sea depth and maneuverability. The SPM is a system that allows mooring to the buoy located in the outer sea for such vessels. However, the buoy is more affected by relatively external forces because of their offshore location. Therefore, the safety assessment of SPM is particularly important as it can lead to large oil pollution disasters in the event of SPM accidents. Despite this, in the implementation of the Marine Traffic Safety Audit Scheme in Korea, there exists no guidance for SPM. In this study, a SPM mooring safety assessment is performed using OPTIMOOR, a numerical analysis program, so as to understand the mooring characteristics of SPM. As a result, it is confirmed that the tension of mooring lines and hull movement in the SPM are greatly affected by the encounter angles with external forces. In addition, it is found that the maximum tension of the mooring line is elevated as the water depth becomes shallower through sensitivity analysis. According to SPM characteristics, which has a large influence on the encounter angle, this study has proposed an amendment to setting criteria in the implementation of the Maritime Traffic Safety Audit Scheme which could improve the reliability and accuracy of mooring safety assessments.

Seismic performance of ordinary reinforced concrete shear wall systems commonly used in high-rise residential buildings is evaluated. Three types of shear walls exceeding 60m in height are designed by performance-based seismic design. Then, incremental dynamic analysis is performed collapse probability is assessed in accordance with the procedure of FEMA P695. As a result, story drift, plastic rotation, and compressive strain are observed to be major failure modes, but shear failure occur little. Collapse probability and collapse margin ratio of performance groups do not meet requirement of FEMA P695. It is observed that critical wall elements fail due to excessive compressive strain. Therefore, the compressive strain of concrete at the boundary area of the shear wall needs to be evaluated with more conservative acceptance criteria.

The coastal composite fishery has the highest rate of around 30.0% in registered fishing vessels of Korea for the last three years. The risk analysis for the fisher’s safety of coastal composite fishing vessels was conducted to serve as a basic data for improving the healthy and safe working environment of fisher using fisher’s occupational accidents of the national federation of fisheries cooperatives (NFFC) from 2016 to 2018 (n = 1,105). As a result, the occupational accident occurrence rate of coastal composite fishery was 3.76% in all industries, 7.8 times the rate of that. In addition, death and missing rate was found to have a serious level management to 10.10‱. Among the accidents, 76.0% occurred at sea. The slipping, others and contact with machinery or fishing gear occurred more frequently in order in the frequency of accident occurrence pattern. In the risk assessment using frequency and severity, slipping, contact with machinery and others showed high risk during fishing. The results are expected to contribute to identification and assessment of safety hazard occurred in coastal composite fishing vessels.

The antioxidant activity, total phenol content, and inhibitory effect of xanthine oxidase (XOase) for six different medicinal plant complexes such as Achyranthes japonica, Acanthopanax sessiliflorus, Carthamus tinctorius, Eucommia ulmides, Viscum album, and Caragana koreana were investigated in this study. The free radical scavenging activity values using DPPH(2,2'-diphenyl-1-picrylhydrazyl) and ABTS[2,2'-Azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt radical cation] analyses were found to be 532.03±86.60 μg/mL and 1376.50±35.01 μg/mL, respectively, in 95% of ethanol extracts among six medicinal plant mixed compositions (6MPMC). The total phenolic content in 70% ethanol extract of 6MPMC was 125.19±1.34 mg GAE/g. The inhibitory activity against XOase was highest at 33.20±0.17% in the 70% ethanol extract of 6MPMC. In the antimicrobial activity test of 6MPMC, the minimum inhibitory concentration (MIC) value showed activities against V. litoralis and E. coli in 70% and 95% ethanol extracts, and these two microorganisms were created in clear zones by method of paper disc diffusion. These results suggest that the 6MPMC, composed of Achyranthes japonica, Acanthopanax sessiliflorus, Carthamus tinctorius, Eucommia ulmides, Viscum album, and Caragana koreana, have both antioxidant and antimicrobial activities and, therefore, may serve as a functional health food product.

This study is aimed to take a stock assessment of blackthroat seaperch Doederleinia seaperch regarding the fishing effort of large-powered Danish Seine Fishery and Southwest Sea Danish Seine Fishery. For the assessment, the state-space model was implemented and the standardized catch per unit effort (CPUE) of large powered Danish Seine Fishery and Southwest Sea Danish Seine Fishery which is necessary for the model was estimated with generalized linear model (GLM). The model was adequate for stock assessment because its r-square value was 0.99 and root mean square error (RMSE) value was 0.003. According to the model with 95% confidence interval, maximum sustainable yield (MSY) of Blackthroat seaperch is from 2,634 to 6,765 ton and carrying capacity (K) is between 33,180 and 62,820. Also, the catchability coefficient (q) is between 2.14E-06 and 3.95E-06 and intrinsic growth rate (r) is between 0.31 and 0.72.
