        임석 경기대학교 관광전문대학원 2020 국내석사

        RANK : 247631

        본 연구는 문화관광해설사의 해설을 제공받는 관광객들을 대상으로 마음챙김과 장소애착의 영향관계를 파악하여, 향후 관광해설이 관광객과 해설사, 나아가 지역사회와 상생협력을 어떻게 진행해야 하는지에 대한 시사점을 제시하려는 목적에서 출발하였다. 본 연구의 목적을 달성하기 위해 관광해설, 마음챙김, 장소애착에 대한 개념 및 관련 선행연구를 고찰하여 관광해설, 마음챙김, 장소애착에 대한 요인과 측정문항을 도출하였다. 연구 대상지는 강진군으로 설정하였으며, 강진군에서 운영중인 대구, 부산, 광주에서 출발하는 광역시티투어버스와 수도권 여행사의 강진패키지 상품을 중심으로 2018년 3월 1일부터 4월 30일까지 설문조사를 실시하였다. 그 결과 총 240부의 설문지를 회수하였으나 불성실하게 응답한 설문지 16부를 제외하고 총 224부를 분석에 활용하였다. 분석방법으로는 모집된 표본에 대하여 빈도조사와 기술통계를 실시하였고, 측정척도에 대하여 타당도 분석과 신뢰도 분석, 상관관계 분석을 실시하였다. 그리고 관광해설과 마음챙김, 장소애착 요인간의 영향관계를 분석하기 위해 구조방정식모형분석을 실시하였다. 이러한 분석 과정을 통해 얻은 연구의 결과는 다음과 같다. 첫째, 인구통계학적 특성을 분석한 결과 방문경험 비율은 첫 방문이 76.6%, 재방문이 23.7%로 첫 방문 비율이 높은 것으로 나타났다. 남녀 비율은 여성이 77.7%, 남성이 22.3%로 나타났으며 거주지는 대구가 40.2%, 수도권이 36.6% 순으로 나타났으며, 연령은 30대 이하 2.2%, 40대 12.5%, 50대 46.4%, 60대 33.5%, 70대 이상 5.4%로 중·장년층의 비중이 높은 것으로 나타났다. 학력은 고등학교 졸업이 41.1%로 가장 많은 것으로 나타났으며, 대학교 재학/졸업이 30.8%, 전문대 재학/졸업이 20.1%, 대학원 재학/졸업이 6.7%, 기타 1.3% 순으로 나타났다. 직업은 전업주부가 36.6%, 사무/관리직이 18.8%, 기타 13.4%, 자영업이 9.4%, 전문직이 8.9%, 판매/서비스직이 7.1%, 생산직이 3.1%, 농/임/축산업이 2.7% 순으로 나타났다. 둘째, 실증적인 분석을 통해 타당성 및 신뢰도를 검증하였으며, 관광해설은 2개의 요인으로 도출되어 요인 1은 6개 항목(이미지, 가치, 활동, 교육, 역사, 유익)으로 관광해설 가치로 명명하였고 요인 2는 6개 항목(이해, 지루, 지식, 다양, 흥미, 상세)으로 관광해설 이해로 명명하여 분석에 활용하였다. 마음챙김은 단일요인으로 6개 항목(관심, 궁금, 재미, 흥미, 새로움, 기여)으로 모두 분석에 이용하였다. 장소애착은 3개의 요인으로 요인 1은 3개 항목(자아진정, 자아지각, 자아가치)으로 장소정체성, 요인 2는 5개 항목(추천장소, 상기장소, 우위장소, 선호장소, 최고장소)으로 장소의존성, 요인 3은 3개 항목(순간애착, 소속감, 강한애착)으로 사회적 애착 요인으로 분석에 활용하였다. 셋째, 연구가설 검증을 위하여서 구조방정식모형 분석을 실시하였다. 관광해설은 마음챙김(H1), 마음챙김은 장소애착(H2), 관광해설은 장소애착(H3)에 정(+)의 영향을 미친다는 가설을 설정하여 검증하였다. 분석결과를 살펴보면 관광해설은 마음챙김, 마음챙김은 장소애착, 관광해설은 장소애착 모두 유의수준 내에서 정(+)의 영향을 미친다고 나타났다. 이를 종합하면 지역을 찾은 관광객을 대상으로 문화관광해설사의 관련 해설 서비스를 제공하면 선행연구 등을 통한 알려진 것처럼 장소에 대한 애착이 높아지는 것 외에 그 해설을 통하여 관광객들의 지역에 관한 관심 및 궁금증 등을 유발할 수 있는 마음챙김에 영향을 미치며, 관광해설을 통한 마음챙김의 변화는 장소애착에 긍정적인 영향을 미치는 것을 알 수 있었다. 결국 관광해설은 단순히 정보를 전달하는 역할에서 벗어나, 해설사와 관광객과의 상호관계 속에서 지각되는 마음챙김이 관광객들로 하여금 장소애착 형성에 영향을 주고, 장소애착은 지역의 긍정적인 이미지 형성과 재방문으로 이어지므로 관광해설은 해설사와 관광객의 교감만을 위한 관계가 아니라, 관광객이 지역사회를 긍정적인 측면으로 바라보게 하여 지역에 대한 어떠한 기여를 할 것인가에 대한 해답을 제시할 수 있으며, 결과적으로 해당 지자체가 관광해설의 정책적 방향 설정에 도움이 될 것으로 보인다. The purpose of this study was to identify the influence of mindfulness and place-attachment for tourists who were provided with explanations of the Culture and Tourism Explanation, and to suggest how future tourism interpretations should proceed with tourists, commentators, and, in addition, win-win cooperation with the community. In order to achieve the purpose of this study, factors and measurement questions on tourism description, mind-bending, location-attaching concepts and relevant prior research were derived. The locations for the study were set up as Gangjin-gun, and the survey was conducted from March 1 to April 30, 2018, focusing on the metropolitan city tour buses and the Gangjin package products from Daegu, Busan and Gwangju, which are operating in Gangjin-gun. As a result, a total of 240 questionnaires were retrieved but a total of 224 were used for the analysis, excluding 16 questionnaires who were unfaithful in responding. As an analysis method, frequency survey and technical statistics were conducted on the recruited samples, feasibility analysis, reliability analysis, and correlation analysis were conducted on the measurement scale. And a structural equation model analysis was conducted to analyze the impact of tourism analysis, entrenchment, and location-attaching factors. The results of the studies obtained through this analysis are as follows. First, an analysis of demographic characteristics showed that the ratio of visit experience was 76.6 percent for the first visit and 23.7 percent for the second visit, with the ratio of first visit being high. The ratio for men and women was 77.7 percent for women, 22.3 percent for men, 40.2 percent for Daegu and 36.6 percent for the Seoul metropolitan area, 2.2 percent for those in their 30s or younger, 12.5 percent for those in their 40s, 46.4 percent for those in their 50s, 33.5 percent for those in their 60s and 5.4 percent for those in their 70s. High school graduates accounted for the largest portion with 41.1 percent, followed by 30.8 percent for college/graduates, 20.1 percent for junior college/graduates, 6.7 percent for graduate/graduates and 1.3 percent for others. The number of full-time housewives came in at 36.6 percent, followed by 18.8 percent for office/management positions, 9.4 percent for self-employed businesses, 8.9 percent for professional workers, 7.1 percent for sales/service workers, 3.1 percent for production workers and 2.7 percent for farming, forestry and livestock industries. Second, feasibility and reliability were verified through empirical analysis, and tourism description was derived from two factors, and factor 1 was named tourism description value in six categories (image, value, activity, education, history, benefits), and factor 2 was used to understand tourism description in six categories (understanding, boredom, knowledge, diversity, interest, and detail). As a single factor, six items (attention, curiosity, fun, interest, novelty, contribution) were all used for analysis. Place attachment was used as three factors (self-identification, self-awareness, and self-value) for location identity in three categories, and factor 2 as five items (recommended location, place of preference, preference location) for location dependency and three factors as social factors (instant love, belonging, and strong attachment factors). Third, a structural equation model was analyzed for the verification of the research theory. The tourism explanation was verified by setting up and verifying the hypothesis that the tourism explanation has a positive influence on the place attachment (H1), the place attachment (H2), and the tourism interpretation (H3). According to the analysis results, tourism interpretation have a positive effect within a significant level. To sum up this information, we could see that providing a related commentary service for tourists visiting the area, in addition to increasing their attachment to the place, as is known through prior research, affects the mindfuless that can cause tourists' interest in the area and curiosity, and that changes in the mindfulness through the tourism interpretation have a positive effect on the place-attachment In the end, tourism interpretation is not just about the role of conveying information, but also about the contribution of tourists to the region, as the perceptible mind-twisting between commentators and tourists affects the formation of a place-altering relationship and the location-relationship leads to the formation of a positive image of the region and the re-visiting of the local tourism organization.

        In this thesis, a series of Zr(IV)-based metal-organic frameworks (MOFs) with various porous structures and functional groups were synthesized, and employed for removal of organic pollutants of nonsteroidal anti-inflammatory pharmaceuticals and recovery of precious metals (PMs) of Palladium(II), Platinum(IV) and Aurum(III) from aqueous solutions. In Chapter 3, MOFs of MOF-802, UiO-66 and MOF-808, as well as post-synthesized MOFs of UiO-66-NH2 and UiO-66-NHCOCH3 with significant difference of structures, such as various porous properties, functional groups, and Zr6-node connectivities, were fabricated, and their crystallology, porous properties and morphology were investigated. In Chapter 4, we reported that Zr(IV)-based MOFs (defective UiO-66, and MOF-808) have extraordinary adsorption ability to remove nonsteroidal anti-inflammatory pharmaceuticals from water. Excellent adsorption performances are obtained for UiO-66 and MOF-808, particularly for UiO-66, of which the adsorption capacities are the highest in a wide series of adsorptive materials previously reported, such as activated carbon, zeolites, graphenes, resins, carbon nanotubes, and other MOF materials. It is elucidated that the incomplete-coordinated cationic Zr in the cluster has high affinity for the anionic pharmaceutical (chemical adsorption) and that the adsorption interaction between the benzene ring of the pharmaceutical and MOF’s ligand is involved to enhance or as an alternative to the adsorption interactions (π-π interaction). In particular, adsorption of ibuprofen, ketoprofen, naproxen, indomethacin, and furosemide by UiO-66 and MOF-808 and the synergetic effect of chemical adsorption and π-π interaction are outstanding, leading to extremely higher binding energies (Ebind) and sorption abilities. In Chapter 5, MOFs of MOF-802, UiO-66 and MOF-808 with significantly different structures, such as various porous properties and Zr6-node connectivities, were fabricated and tested for the recovery of PMs of Pd(II) (PdCl42-) from acidic aqueous solutions. Adsorption kinetic and isotherm studies showed structure-controlled recovery performance of Pd(II). Among these MOFs, MOF-808 showed the most rapid Pd(II) uptake and the highest adsorption capacity (the maximum adsorption capacity of 163.9 mg g-1) with achieving the equilibrium within 3 minutes, which could be attributed to the most convenient diffusion of PdCl42- through the largest pores of MOF-808, and the most abundant binding sites in the 6-connected Zr6-nodes, as well as the adequate inner space for accommodating PdCl42-, respectively. However, the MOF-802 exhibited the slowest uptake yet highest affinity for Pd(II) with the best adsorption performance in low concentration Pd(II) solutions. This is likely because of the extremely high binding energy (Ebind) between protonated amine groups of MOF-802 and the PdCl42-. Furthermore, the high adsorption selectivity for Pd(II) and good regeneration performance of MOF materials were observed, showing their potential for further large-scale applications. In Chapter 6, two Zr(IV)-based MOFs of UiO-66 and UiO-66-NH2 with incomplete-coordinated Zr6 node were fabricated and tested for adsorption of Pd(II), Pt(IV) and Au(III) anions (PdCl42-, PtCl62- and AuCl4-) in strongly acidic solutions. Both MOFs were tested for uptake time and adsorption capacities and showed rapid and high precious metal adsorption performances. Inner-sphere complexation between the precious metal anions and the incomplete-coordinated Zr atoms in the MOFs was the key mechanism involved in the precious metal adsorption. In the case of UiO-66-NH2, additional electrostatic attraction was found between the protonated amine group (–NH3+) and the precious metal anions, as well as partial reduction of the bound precious metal ions. Moreover, the pathway of adsorption-reduction-crystallization-precipitation for the interaction of UiO-66-NH2 and AuCl4- resulted in extremely high recovery efficiency for gold. Furthermore, the high selectivities of UiO-66 and UiO-66-NH2 for Pd(II), Pt(IV) and Au(III) amid coexisting interfering metals, as well as the stable performances over five cycles of adsorption-desorption showed their potential in practical applications for the recovery of precious metals. In Chapter 7, Zr(IV)-cluster-based MOFs were synthesized for the selective adsorption of Pd(II), as a model precious metal ion, from acidic aqueous solutions containing Co(II), Ni(II), Pd(II), and Pt(IV). Among the various Zr-MOFs synthesized (i.e. UiO-66, UiO-66-NH2 and UiO-66-NHCOCH3), UiO-66-NH2 showed the highest Pd(II) selectivity, with the Pd(II) uptake in the mixture-metals solution being around 181 times higher than that of Pt(IV). The Pd(II) selectivity of UiO-66-NH2 was attributed to higher binding affinity of the protonated amino groups (−NH3+) for PdCl42- and more convenient diffusion of the PdCl42- through the apertures (pores) of the UiO-66-NH2 − which have the appropriate inner sizes befitting PdCl42- penetration − than for Pt(IV) ions (PtCl62-). Furthermore, UiO-66-NH2 showed a stable selective adsorption performance for Pd(II) over five cycles of adsorption-desorption from Pd(II)-Pt(IV) binary solution. In Chapter 8, a set of polymeric nanofibrous membranes incorporated with the UiO-66 series are fabricated; their adsorption/desorption capabilities towards Pd(II) and Pt(IV) are evaluated from strongly acidic solutions; and the MOF-polymer compatibilities are investigated. Polyurethane/UiO-66-NH2 showed strong acid resistance and high chemical stability, which are attributable to strong π-π interactions between PU and MOF nanoparticles with a high configuration of energy. The as-fabricated MOF membranes show extremely rapid uptake rates, large uptake amounts in terms of adsorption kinetics, and isotherms without ruptures/coalitions of nanofibers or leak of MOF nanoparticles, and successfully display the adsorption and desorption efficacy in a gravity-driven or even continuous-flow system, thus showing ultrafast adsorption performance among various adsorbents. Furthermore, good recycle performance and selectivity were also verified. The as-fabricated MOF membranes set an example of potential MOF-polymer compatibility as well as potential for practical applications. Finally, we believe that this thesis suggests MOF materials as new alternatives to adsorptive capture and separation of organic pollutants and precious metal ions from aqueous phase, and extend the application of Zr-based MOFs in the fields of environmental protection and sustainability at the mean while.

        부분적으로 에폭시화된 대두유(pESO)와 완전히 에폭시화된 대두유(fESO)가 각각 비스페놀 A 다이글리시딜 에테르(DGEBA) 수지 계의 개질을 위해 사용되었다. pESO는 대두유를 에폭시화하여 준비하였고, fESO는 상업적으로 이용가능한 것으로 구입하였다. 바이오 에폭시 수지 계의 DGEBA/ESO 비율을 100/0에서 70/30으로 변화시켰으며, 트리에틸렌테트라민(TETA)을 경화제로 사용하였다. fESO를 사용한 바이오 에폭시 수지 계의 충격강도는 ESO의 함량에 따라 증가하였지만, pESO를 사용한 바이오 에폭시 수지 계의 충격강도는 ESO의 함량에 따라 감소하였다. ESO의 함량이 30 wt%일 때, pESO를 사용한 바이오 에폭시 수지 계의 인장강도와 파단신율은 fESO를 사용한 바이오 에폭시 수지 계보다 높은 결과를 보였다. 바이오 에폭시 수지 계에 사용된 ESO의 종류에 관계없이 인장탄성률과 열적 저하 온도는 ESO의 함량이 증가할수록 감소하는 결과를 보였고, 유리전이온도는 ESO의 함량이 20 wt%일 때 가장 높은 결과를 보였다. 추가적으로, DGEBA/ESO 비율이 70/30으로 고정된 조건 하에 pESO와 fESO의 함량을 100/0에서 0/100으로 변화시켜 혼합한 후 바이오 에폭시 수지 계에 도입하였다. 혼합된 ESO를 사용한 계의 기계적 특성은 이전 결과에서 나타난 경향대로 나타났지만, 열적 안정성은 pESO 또는 fESO를 각각 사용한 계와 비교했을 때 더 좋은 결과를 보였다. DGEBA/ESO 바이오 에폭시 수지 계의 특성은 ESO의 함량 및 관능기를 변화시킴으로써 조정할 수 있었다. Partially epoxidized soybean oil (pESO) and fully epoxidized soybean oil (fESO) were used respectively to modify a diglycidyl ether of bisphenol A (DGEBA) resin system in this study. The pESO was prepared by epoxidizing soybean oil and the fESO was purchased as it was commercially available. DGEBA/ESO ratio of the bio-epoxy resin system was changed from 100/0 to 70/30 and triethylenetetramine (TETA) was used as a curing agent. Impact strength of the bio-epoxy resin system with fESO increased with ESO content, but the system with pESO decreased with ESO content. The bio-epoxy resin system with pESO showed higher tensile strength and elongation at break than the system with fESO at ESO 30 wt%. Tensile modulus and thermal degradation temperature decreased with ESO content and glass transition temperature was highest at 20 wt% ESO regardless of epoxide functionality of ESO. Additionally, the pESO and fESO were mixed at the ratio from 100/0 to 0/100 and introduced to the bio-epoxy resin system under the condition of 70/30 of DGEBA/ESO ratio. The mechanical properties of the system with mixed ESO appeared to the tendency of previous results, but thermal stability was better compared to the systems with pESO or fESO respectively. The performance of the DGEBA/ESO bio-epoxy resin system could be tailored by changing ESO content and functionality.

        Recently, there is tendency to increase the interest and demand on nursery due to expend of Korean woman's participation in our society. In order to meet the demand of nursery education, the government significantly expanded nursery facilities from 1995 to 1997, using the amount of ₩130,000,000,000 of government support and borrowed money from the government pension fund. Since then, the government has expressed the interest on this issue consistently. In the past, the concept of nursery education is just only providing child care, however, this concept has changed significantly in modern society. In rapid change modern society, the concept of nursery education devide two major concepts. One is the concept of provide child day care and the other is the concept of child education. The reason of these need is that the woman has had higher education and improve of their social status in our modern society. Many of them have their job after completed their education. In the case of working woman, they desire to provide excellent child care with safe and healthy environment at nursery for their children. In addition to this, they expect high quality education from professional child care educator with systematic curriculum for their child. They also consider that the early child education is very important and they want to provide various experience for their infant and preschool children from facility. According to the law of early child education, the type of facility for early child education are federal and national nursery, private nursery, child care center from job, and day care center from home. The purpose of this research is to improve the quality of care for early child education and recommend to various operational program in nursery with this research results. In order to accomplish this purpose, the researcher designs to compare the operation of facility for early child education between incorporation nursery(not owned by owner) and private owned nursery among private nursery facilities. The researcher also designs to compare satisfaction survey from the parents of the facilities for early child education and care. This researcher designs with two research questions :1. What is the difference of actual operational condition of nursery facilities between incorporative nursery and private owned nursery? 2. What is the difference on satisfaction of parents of nursery child regarding the service of early child education? The sample of this research are the parents of nursery child and general managers of nursery facilities. The sample size is two hundred fifty parents of nursery child and eighty general managers of facilities. The method of this research use the interview for general managers of each facility and visit the facilities, and refer the questionnaire for parents to each facility. The researcher recommend as the below according to the outcome of this research. 1. It must prepare the resolution to support the private owned nursery with financial problem. With this reason, private owned nursery provides low quality care and education for the children and increase turn over rate of teachers in those nursery. Moreover, it contributes the negative outcome of early child care and education in this country and fades the purpose of early child education and care. Therefore, the government should consider the financial support and make effort to improve these private owned nursery. 2. Among the facility of early child education and care should be treated differently, especially between Incorporative nursery and Private owned nursery. Since the incorporative nursery operates with mission of welfare and complies with the law of early child education and care in this country. In contrast, the private owned nursery operates the base on economical principle such as demand and supply rule in market place.
