우리가 어떠한 상황에서 불안해진다는 것은 다가올 미래에 대해 확실하게 준비할 수 없다는 사실에 근거합니다. 수많은 선각자와 학자들은 모두들 이러한 불확실성으로 인한 위험 요소들을 확실하게 밝히고자하며 이로 인해 우리로 하여금 더욱 과학적으로 상황을 대처하고 극복하게 하려 합니다. 아시아 지역의 호텔관광시장에 대해 이곳에서 논의되는 것은 과거와 현재 그리고 미래를 넘나들며 현재 이 시장에서 벌어지는 새로운 경향을 파악하고 파악된 자료를 통해 도전과 위험요소를 인지케하는 내용들입니다. 과거는 현재의 원인이 될 수 있고 과거의 흔적은 내일의 같은 형태의 현상이 될 수 있다고 보기에 우리는 미래의 시장을 예측하려 할 때 과거를 검증하고 현재를 숙독해야 하는 것입니다. 과거 속에서 우리는 한때 우리 시장의 고객들이 사회적 성공의 표시로 여행을 즐겼으며, 그것이 전쟁 등과 같은 힘든 시절을 보내면서 휴식과 교육을 목표로 여행을 즐기던 시절이 있었고, 이것이 다시 최근에 들어 고객들의 자기충족과 자아실현의 방법으로 여행을 즐기고 있음을 감지할 수 있습니다. 이러한 경향들의 연장선상에서 우리의 호텔시장은 호텔이 고도로 품격화된 개인적인 서비스를 제공하게 될 것이고, 발달된 정보기술력으로 인해 편리하게 자산관리를 할 수 있고, 쉽게 접근이 가능한 투자자본으로 인해 소유주의 형태가 다국적으로 다각화되는 결과를 낳게 될 것이고, 수많은 패턴들이 존재하지만 기술력의 혁신으로 인해 이를 통한 새로운 상품과 서비스의 개발이 가장 두드러지는 시장이 될 것이 분명합니다. 관광시장에서는 크게 두 영역으로 분리해서 본다면, 하나는 새로운 형태의 고객이고 또 하나는 관광이란 것이 거리를 요하는 것이기에 이를 극복하고자 하는 기술력을 동원한 새로운 형태의 관광체험이라 할 수 있습니다. 새로운 형태의 고객은 보다 자유롭고 의사표현이 열려있는 고객이며 이들은 각자의 자아실현과 충족을 위해 끊임없이 새로운 여행 목적지를 찾는 고객이며, 복잡하지 않고 단순한 형태의 상품과 서비스를 요하며 그들은 또한 시작에서 마무리까지 완성된 서비스를 추구하는 고객이 될 것입니다. 거리를 초월하는 기술력의 발달로 고객은 원거리에서 자기자신의 여행 진행 전부를 쉽게 컨트롤 할 수 있게 되고 특히 가상 현실실현에 대한 기술력은 멀리서도 원거리의 여행 체험을 실제와 버금가게, 그리고 현실에서 겪어야 하는 일체의 장애 없이 체득할 수 있게되는 상황을 고객 앞에 내놓게 될 것입니다. 우리는 지금 새로이 중흥하려 노력하는 아시아의 주요 국가의 호텔관광산업을 의미 있게 짚어보고 내일을 함께 준비하고 있습니다. 여기에 논의되어진 이슈가 아니더라도 우리는 그것들을 새로운 시각에서 검증하고 분석하여 새로이 전개되는 미래의 아시아 호텔관광산업을 함께 준비해야 할 줄 믿습니다.

Smart clothing represents the future of both the textile/clothing industry and electronic industry and has an effort to make electronic devices a genuine part of our daily life. The researches about technologies innovation and application of smart clothing can be found in previous studies. But consumer researches about perception or attitude toward smart clothing can be hardly found. Therefore, we proposed a conceptual framework that explores the impact of perceived risks on perceived attributes to adopt smart clothing. In addition, we compared differences of this framework among three counties. Korea, U.S. and Spain. Based on the literature review and hypotheses development, a research model was constructed. After data analysis using Amos 7.0, the results can be concluded as following: First, the influences of psychological risk among Korea, U.S. and Spain are same. Psychological risk has negative effect on relative advantage and complexity, but has positive effect on trialability. Second, loss risk was found to have nothing to do with relative advantage. But it negatively influences complexity for Korean consumers and positively influences trialability for both Korean and American consumers. Third, the influences of performance risk for different consumers are different. At last, based on our discussion, some implications were also concluded.

산업발전에 따른 인구증가, 기후위기에 따른 가뭄 및 물 부족심화, 그리고 수질오염 등은 2015년 제79차 UN총회의 물 안보측면에서 국제사회의 물 분야 위기관리를 위해 2030년을 지속가능한 발전 목표(Sustainable Development Goals)로 하였다. 또한, 현재 물 산업은 빠르게 성장하고 있으며, 2016년 세계경제포럼(World Economic Forum) 의장 클라우스 슈밥(Klaus Schwab)부터 주창된 제4차 산업혁명로 인해 현재 물 산업의 패러다임 또한 급속히 변화하고 있다. 이는 컴퓨터를 기반으로 하는 CPS(Cyber Physical System) 및 DT(Digital Twin) 연계 분석방식의 혁신을 일컫는다. 2002년경에 DT의 기본개념이 제시되었고, 2006년경에는 Embedded System에서의 DT와 같은 개념으로 CPS의 용어가 등장했다. DT는 현실세계에 존재하는 사물, 시스템, 환경 등을 S/W시스템의 가상공간에 동일하게 모사(Virtualization) 및 모의(Simulation)할 수 있도록 하고, 모의결과를 가상시스템으로 현실세계를 최적화 체계 구현 기술을 말한다. DT의 6가지 기능은 ① 실제 데이터(Live Data), ② 모사, ③ 분석정보(Analytics), ④ 모의, ⑤ 예측(Predictions), ⑥ 자동화(Automation) 이다. 또한, CPS는 대규모 센서 및 액추에이터(Actuator)를 가지는 물리적 요소와 이를 실시간으로 제어하는 컴퓨팅 요소가 결합된 복합시스템을 말한다. CPS는 물리세계에서 발생하는 변화를 감지할 수 있는 다양한 센서를 통해 환경인지 기능을 수행한다. 센서로부터 수집된 정보와 물리세계를 재현 및 투영하는 고도화된 시스템 모델들을 기반으로 사이버 물리공간을 인지·분석·예측할 수 있다. CPS의 6가지 구성요소는 ① 상호 운용성(Interoperability), ② 가상화(Virtualization), ③ 분산화(Decentralization), ④ 실시간(Real-time Capability), ⑤ 서비스 오리엔테이션(Service Orientation), ⑥ 모듈화(Modularity)이다. DT와 CPS는 본질적으로 같은 목적, 내용, 그리고 결과를 만들어내고자 하는 같은 종류의 기술이라고 할 수 있다. CPS 및 DT는 물리세계에서 발생하는 변화를 감지할 수 있으며, 토양-지하수 센서를 포함한 관측기술을 통해 환경인지 기능을 수행한다. 지하수 관측기술로부터 수집된 정보와 물리세계를 재현 및 투영하는 고도화된 시스템 모델들을 기반으로 사이버 물리공간 및 디지털 트윈 공간을 인지·분석·예측할 수 있다. CPS 및 DT의 기본 요소들을 실현시키는 것은 양질의 데이터를 모니터링할 수 있는 정확하고 정밀한 1차원 연직 프로파일링 관측기술이며, 이를 토대로 한 수자원 관련 빅데이터의 증가, 빅데이터의 저장과 분석을 가능하게 하는 플랫폼의 개발이다. 본 연구는 CPS 및 DT 기반 토양수분-지하수 관측기술을 이용한 지표수-지하수 연계, 지하수 순환 및 관리, 정수 운영 및 진단프로그램 개발을 위한 토양수분-지하수 관측장치를 지하수 플랫폼 동시성과 디지털 트윈 시뮬레이터 시스템 개발 방향으로 제시하고자 한다.

It is well known that compensation satisfaction of employees is closely related to work attitude, job commitment, and employees'intentions to stay on the job. These known facts can also be applied to the professionals engaged in science & technology as well. Many studies have concluded that the Korea's losing competitiveness in the area of science & technology was mainly attributed to the distorted compensation system. In this vein, this paper identifies the potential determinants that affect the compensation satisfaction of S&T professionals, and to empirically examines the determinants influences on job commitment and intention to stay. This was done by acquiring data from S&T professionals currently being employed in firms, universities, and institutions. Consequently, for professionals engaged in science & technology, the compensation satisfaction was demonstrated to be largely influenced by job accomplishment, monetary compensation, and social compensation in order. In conclusion, to improve compensation system for S&T professionals, firstly, it is recommended to enhance job accomplishment by endowing more discretionary authority to conduct research. Secondly, the relatively lower-valued labor forces in S&T area will necessitate more economic support and compensation. Finally, the social compensation should be strengthened by not only ameliorating social status, but also improving labor liquidity and job security.

Block chains began by recognizing the danger of centralized control of financial systems after the 2008 financial crisis. From the beginning of 2008, blockchain has been developing a lot of attention and technology, starting with a tremendous innovation called cryptographic destruction based on technology, a block chain called Bitcoin. However, the vulnerability has also been discovered over time and the damage has been repeated. But in the fourth industry of the 21st century, many advances and technologies based on them are expected to emerge. Therefore, this paper proposes new analytical transaction protocols for vulnerabilities in cryptographic currency transactions. The proposed transaction protocol is a way to authenticate once again at the end of the transaction and the transaction is concluded with this authentication. It presents countermeasures by adding security elements between users to the transaction process rather than internal security to transaction vulnerabilities.

Many government offices have been proceeding a development of Enterprise Architecture(EA) according to apply Government-wide Enterprise Architecture'. Each office and working-level officials have had a hard time because of no guides related to a EA development method such as the Framework, Standards, Principle, Reference Model, Etc. This paper propose a method for developing e-Government Enterprise Architecture considered a characteristic of public institutes through analyzing existing cases. The method for development e-Government EA includes the EA Performance Management Model to monitor objectively each office's long-term business promotion because the e-Government EA development is a job of long duration and cooperation with many institutes. This method also combines the EA Change Management Activities for the officials to improve general knowledge about EA's idea and EA's value, etc. We show the EA case study of the Ministry of Government Administration and Home Affairs to demonstrate feasibility of our approach. As a result, public offices will carry out their BPR(Business Process Re-engineering) and ISP(Information Strategy Planning) more efficiently based on this EA development method.

This study explored how media and interpersonal communication affected voters in Busan mayoral by-election, focusing on the mutual relations among media use and attentive use of political campaign, interpersonal communication, and voting participation. Also, comparative analysis between image factor and the factor of political party influencing the decision of a candidate were examined. Additionally, it was analysed differential media effects on candidates' image. According to the results, the local media use and attentive use of political campaign had the influence on the increase of interpersonal communication about the election. Voters who had much interpersonal discussion with others participated more than voters who had less interpersonal discussion. Media use did not directly affect the participation of voting, but indirectly contributed to participation of voting through interpersonal discussion. The assumption of differential media effects on candidates image was partly proved. There were statistically significant differences in the factor of competence of candidates' image among three experimental groups (attentive use of TV discussion program, Internet web sites of two candidates, and printing materials of political advertisement). Furthermore, with three main vote variables, issues, candidates image, party identification, the results of comparative analysis between image factor and the factor of political party influencing the choice of a candidate suggested that a sense of oneness with a party was highly related to the choice of the candidates of the party, however, candidates' image was not related to the decision of a candidate. Political party had more impact on for whom to vote than candidates' image in this study.

The university is attempting educational innovation to cultivate talents required by society. The purpose of this study was to prove the educational effect by applying the PBL to on a fashion theoretical course. The research methods are theatrical research and model development research to guide to utilizing PBL. As a result of this study, the learners' satisfaction with the subject applying PBL was evaluated quite positively. In general, it has been shown to have a very effective effect on improving the learner's problem-solving capability, cooperative learning capability, and self-directed learning capability. In particular, the problem-solving capability is relatively high compared to other factors. The result is consistent with the educational goal of the PBL for improving the learner's problem-solving capability. Perceivable correlation analysis on the relationship between the factors to grasp the educational effect of the PBL revealed the factors with a static correlation. In particular, the problem solving capability and cooperative learning capability developed a significant correlation with self-directed learning capability. This is a testament to their ability to exert greater influence when the competencies that each learner develops are combined.
