본 연구는 관광행태의 종단연구를 통해 광한루원 관리방향 설정을 위한 기초자료를 얻기 위하여 수행되었으며, 2005년과 2018년 광한루원에서 설문조사한 내용을 비교분석하였다. 방문객의 인구통계학적 특성은 40대 이상의 연령층, 여성, 주부가 상대적으로 많았으며 지역적으로는 충청과 전북 지역의 방문객이 증가하였다. 목표시장의 세분화를 통해 인구통계학적 특성의 변화를 반영하는 관광상품 개발 및 마케팅 전략을 수립해야 할 것이다. 확실한 관광 목적지로서 의 광한루원 위상은 높으므로 다양한 관광요소의 질적 향상을 위한 관리전략의 수립이 뒤따라야 할 것이다. 또한 광한루 주변 관광자원의 개발과 함께 연계이용 교통수단의 운영으로 관광지 간 접근성 증진을 도모해야 한다. 숙박률 향상을 위해 야간 관광지로서의 포지셔닝 전략을 수립하고 숙박 관광객을 유인할 수 있는 숙박시설과 프로그램이 필요하다. 새로운 관광트렌드 에 부응하기 위해서는 먹거리 상품의 다양화와 함께 지자체의 적극적인 지역음식 개발 및 홍보가 이루어져야 한다. 전체 및 남원 관광일정의 변화, 비숙박 비율의 증가에 대응하여 광한루원의 행태적 장 조절과 남원의 독특한 역사문화자원을 활용한 연계 프로그램을 운영하는 생태심리학적 해결책이 필요하다. 특히, 남원 소재 관광지간 낮은 연계이용 비율은 광한루원의 상대적으로 높은 관광 중심성과 함께 매력도가 높은 새로운 관광지가 부족하기 때문이다. 이를 극복하기 위해서는 테마의 동질성, 용이한 접근성을 바탕으로 춘향테마파크 중심의 남원관광단지와 적극적인 연계전략을 수립해야 할 것이다. 전체 관광경로 분석 결과, 단일목적 관광지로서 남원의 위상은 약화되고 연계관광지로서의 역할은 증대되었다. 따라서 인접 지자체와 광역관광 네트워크 전략을 수립하여 지역적 관광매력도를 제고하는 관광지 관리정책도 필요하다고 판단된다.
도시화로 인한 열섬현상은 매년 심각해지고 있으며 도시 내의 온도증가로 인한 피해 또한 증가되고 있다. 최근 도시녹지 조성을 통한 온도저감이 도시열섬현상의 해결방안으로 부각되고 있다. 본 연구에서는 도시 공원녹지의 지형적 특징에 따른 주변 온도저감 효과를 분석하였다. 이를 위해 위성영상을 통해 서울시의 지표면 온도를 구축하였으며 서울시 내의 공원녹지와 녹지 주변에 대한 온도 분석을 실시하였다. 또한 유사한 주변 환경을 가진 공원녹지들을 추출하 고 각 녹지의 지형 요소에 따른 주변 온도저감 효과 분석을 실시하였다. 그 결과 녹지의 고도범위, 부피, 경사도가 증가함에 따라 주변 온도저감효과도 증가하는 것으로 나타났다. 이러한 결과는 향후 공원조성 시 지형적 요소 고려 뿐만 아니라 도시계획 차원에서의 바람길 조성 정책에도 영향을 줄 수 있을 것으로 보인다.
우리나라는 오랫동안 국가경찰체제를 유지해 왔으며, 자치경찰에 대한 요구도 상당기간 지속적으로 제기되어 왔다. 자치분권과 지방자치를 실질화하기 위해 2021년부터 한국에 자치경찰제도가 도입되었다. 이 논문은 2021년부터 시행되는 자치경찰 법제도를 자치분권, 조직구 성의 민주성과 이를 보장하기 위한 주민의 진정한 참여와 통제의 실현, 자치경찰의 효율적 운영을 통해 풀뿌리 주민 자치경찰제도의 실현이라는 관점에서 평가하고 문제점을 분석하였다. 국가경찰과 자치경찰의 조직 및 운영에 관한 법률에 규정된 자치경찰 관련 조항들을 종합적으로 연계하여 살펴보았으며, 개정된 경찰법의 내용을 평가하고 문제점을 도출하였으며 개선을 위한 시사점을 제시하였다. 자치경찰의 사무 배분을 통해 분권화 정도를 분석해 볼 때 자치경찰의 분권화는 매우 미흡한 실정이다. 국가경찰에 의한 자치경찰 사무 집행, 국가경찰과 자치경찰 사무의 중복 및 충돌 우려, 국가경찰의 자치경찰에 대한 관리 감독 문제 등도 도출되었다. 자치경찰위원회의 민주성, 독립성, 인권존중 등은 평가할 만하며, 자치경찰의 신분보장 및 정치적 중립도 보장되고 있지만 자치경찰위원의 자격을 강화할 필요성도 제기되었다. 전체적으로 자치경찰제 시작이라는 역사적 의미는 크지만, 시작 단계에 불과하고 향후 자치분권의 확대, 국가와 자치경찰의 협력 및 자치경 찰권에 대한 국가통제의 완화, 정치적 중립의 확보가 장기적으로 추진되어야 자치경찰의 위상을 찾아갈 수 있을 것으로 보인다.
본 연구는 치유농업 프로그램이 현재 운영되고 있는 현황을 조사하여, 향후 치유농업 산업의 활성화를 위한 정책 수립에 활용하고자 수행하였다. 조사 모집단은 치유농업육성 시범사업에 참여한 173개소의 농장으로 하였으며, 2019년을 기준으로 치유농업 사업을 운영한 농장 중 설문에 응답한 곳은 106개소였다. 조사 결과, 치유농장에서 운영한 프로그램의 개수는 농장당 평균 3.8개였다. 프로그램 운영 기간은 4∼10월에 집중되었다. 대부분은 요일에 관계없이 주중, 주말 모두 운영하였으며 시간대는 주중과 주말이 유사하게 10시에서 16시까지 운영하는 곳이 많았다. 이용객 비중은 단체가 69.1%, 개인이 30.9% 이었으며 프로그램에 활용하는 자원은 식물이 58.8%로 가장 많았다. 치유농업 프로그램 참여 대상은 초/중/고 청소년이 69.8%로 가장 많았으며, 특성별 기준에서는 일반인이 70.8%로 가장 많은 비중을 차지했다. 프로그램 1회당 정원은 평균 26명이었고, 연간 평균 진행 횟수는 19회, 연간 평균 참여 인원은 450명 수준이었다. 치유농업 프로그램 다양화나 대상자 맞춤형으로 활용할 수 있도록 좀 더 심화된 사례조사가 이루어져야 할 것으로 여겨진다.
After the 2008 global financial crisis, China’s banks fled the bogs far better than their counterparties in Europe, the US and Japan. China has achieved outstanding success in modernizing its banking sector and financial markets. The theory of law and finance generally acknowledges a close correlation between vibrant financial growth and a function of legal and regulatory system. But this theory may not apply to China. A group of scholars attributes China’s success to its top-down Party-state model of “rule by law” scheme. This book intends to thoroughly examine China’s financial regulatory system in the first decade after the global financial crisis, and provide insights to China’s market liberalization and economic development. This author indicates that China’s current regulatory system on financial market is still restrictive and mainly government-dominated. To further promote the development of financial markets and market economy, more market-led reforms to regulatory system and the expansion of the markets are needed.
The Biden administration has moved to refocus the US trade policy on China, acting to promote competition but not thoughtless confrontation. Some actions were strong right out of the gate; that should not have been so surprising, but it still was. If anything, the recently concluded G-7 meeting in Cornwall and the subsequent US-EU summit in Brussels indicate that the Biden administration intends to take a stronger and a more multilateral and diplomatic approach to confront China. This approach was further supported by the US allies at the recent NATO meeting in Brussels. The administration is stressing cooperation with allies and competition with China. Biden’s recent diplomacy demonstrates his overriding preoccupation with China. Moving away from Trump’s dysfunctional and disastrous unilateral measures of confrontation with all can only help stabilize the US-China relations and rebuild the WTO, hopefully.
Pakistan is host to the different indigenous peoples’ groups such as “Koochis,” “Rebari,” “Bakarwal,” “Kehal,” “Jogi,” “Kabootra,” “Sanyasi,” and the most famous “Kalash.” By providing them with a proper legal mechanism for the fortification of their inherited resources, culture expressions and outdated information under a thorough intellectual property framework, Pakistan can preserve the already declining population of indigenous people and create better livelihood opportunities for them. They form at present nondominant sectors of society and are determined to preserve, develop, and transmit to future generations their ancestral territories and ethnic identity, as the basis of their continued existence as peoples, in accordance with their own cultural patterns, social institutions and legal system. Many international instruments have been in operation to support their endeavors. They make up to 15 percent of the extreme poor population of the world. Hence there is an urgency to develop laws for them.
The regulation of digital financial assets has been a topic of discussion for many countries over the last decade. China is among the world leaders in the digitalization and blockchain technologies. Under the “one country, two systems,” two different approaches to the digital financial assets have been implemented in the PRC. Although the COVID-19 pandemic has stimulated many investors to diversify their investment portfolios to include digital financial assets, the People’s Bank of China has not changed its prohibitive position on tokens and cryptocurrencies and even launched a campaign against miners and crypto exchanges. Macau and Taiwan have also prohibited initial coin offerings and the transfer of cryptocurrencies due to the risks of money laundering connected with the citizens of mainland China. Macau, Taiwan, and the Monetary Authority of Hong Kong have implemented less stringent regulations of digital financial assets. Comparative analysis demonstrates that Hong Kong acts as an intermediary for China to the digital financial assets.
The Chinese Marriage Law 2001 stipulates two kinds of divorce: registered divorce and litigated divorce. In this paper, the different grounds and procedures related to these two types of divorce will be examined and the judicial statistics and empirical experience about the legal system of grounds for divorce in practice will be explored. Compared to litigated divorce, the easier registered divorce predominates in terms of number. While the sole legal requirement for litigated divorce is that the marriage has broken down irretrievably, this breakdown needs to be evidenced by specific facts. The facts listed in Marriage Law 2001 are mostly fault-based. However, they are not in line with the situation in practice and increase the difficulty of litigated divorce. The legislative reform for the legal grounds for divorce in the Chinese Civil Code (2021) has been undergone in order to strike a balance between protecting people’s autonomy to divorce and assisting people to make divorce decisions.
As Europe is a weaker actor mainly due to her digital underdevelopment, the EU is settling on the regulatory side of digital sovereignty. The article is to comparatively analyze the European and Chinese AI ethical guidelines considering the strategic and normative scope of the guidelines as well as their implications on the legal frameworks of AI both in Europe and China. In this field, the most important initiative in the EU was carried on by the High-Level Expert Group on Artificial Intelligence, which, in 2019, released the “Ethics Guidelines for Trustworthy AI,” a catalogue of principles as well as operative measures to achieve Trustworthy AI. In China, instead, the most important initiative was the “Beijing AI Principles” released in 2019 by the Beijing Academy of Artificial Intelligence, and the “Principles to Develop Responsible AI for the New Generation Artificial Intelligence: Developing Responsible Artificial Intelligence” released in 2019 by the New Generation AI Governance Expert Committee.
The investor-state dispute settlement (ISDS) system is such a means to an end of further economic development and wider social political goals. With major protective provisions of expropriation against compensation, fair and equitable treatment, national treatment, most-favored-nation treatment, full protection and security and umbrella clause, it helps establish a predictable, transparent, and enforceable legal regime to protect foreign investors’ legitimate expectations and lawful investment. As China intends to attract foreign investments by offering a stable business operation environment, its signing a large number of BITs and FTAs may help reduce political and socio-economic risks, which give states, businesses, and individuals the confidence to work in a coordinated manner. The economic development goal, rule of law strategy, tense US-China relations, ideology of multilateralism and community of common destiny, all add up to China’s inclination to incremental but effective ISDS reform.
The EU, China, and other WTO members recently released their concluded MPIA with its Annexes I and II as a temporary arrangement to deal with the appeals of panel rulings before the Appellate Body resumes its operation. The WTO dispute settlement mechanism is a complete unit with unique features and inherent logic. Although this arrangement maintains the two-tier process with arbitration to replace the appellate review, there is a fundamental difference between them, which is embodied not only in the dispute settlement process but also in the implementation of the rulings. The challenges that the WTO dispute settlement mechanism encounters are not limited to those procedural issues, but they are also connected with the substantive rules, with which the procedural issues should be jointly resolved. This is the correct way to deal with the current challenges and to reform the multilateral trade regime.
Because of its unique properties, tungsten is a strategic and rare metal used in various industrial applications. However, the world's annual production of tungsten is only 84000 t. Ammonium paratungstate (APT), which is used as the main intermediate in industrial tungsten production, is usually obtained from tungsten concentrates of wolframite and scheelite by hydrometallurgical treatment. Intermediates such as tungsten trioxide, tungsten blue oxide, tungstic acid, and ammonium metatungstate can be derived from APT by thermal decomposition or chemical attack. Tungsten metal powder is produced through the hydrogen reduction of high-purity tungsten oxides, and tungsten carbide powder is produced by the reaction of tungsten powder and carbon black powder at 1300–1700oC in a hydrogen atmosphere. Tungsten scrap can be divided into hard and soft scrap based on shape (bulk or powder). It can also be divided into new scrap generated during the production of tungsten-bearing goods and old scrap collected at the end of life. Recycling technologies for tungsten can be divided into four main groups: direct, chemical, and semi-direct recycling, and melting metallurgy. In this review, the current status of tungsten smelting and recycling technologies is discussed.
In this study, a nanocrystalline FeNiCrMoMnSiC alloy was fabricated, and its austenite stability, microstructure, and mechanical properties were investigated. A sintered FeNiCrMoMnSiC alloy sample with nanosized crystal was obtained by high-energy ball milling and spark plasma sintering. The sintering behavior was investigated by measuring the displacement according to the temperature of the sintered body. Through microstructural analysis, it was confirmed that a compact sintered body with few pores was produced, and cementite was formed. The stability of the austenite phase in the sintered samples was evaluated by X-ray diffraction analysis and electron backscatter diffraction. Results revealed a measured value of 51.6% and that the alloy had seven times more austenite stability than AISI 4340 wrought steel. The hardness of the sintered alloy was 60.4 HRC, which was up to 2.4 times higher than that of wrought steel.
The effects of drying temperature on the microstructure of porous W fabricated by the freeze-casting process of tert-butyl alcohol slurry with WO3 powder was investigated. Green bodies were hydrogen-reduced at 800oC for 1 h and sintered at 1000oC for 6 h. X-ray diffraction analysis revealed that WO3 powders were completely converted to W without any reaction phases by hydrogen reduction. The sintered body showed pores aligned in the direction of tertbutyl alcohol growth, and the porosity and pore size decreased as the amount of WO3 increased from 5 to 10v ol%. As the drying temperature of the frozen body increased from -25oC to -10oC, the pore size and thickness of the struts increased. The change in microstructural characteristics based on the amount of powder added and the drying temperature was explained by the growth behavior of the freezing agent and the degree of rearrangement of the solid powder during the solidification of the slurry.
In this study, a ZnS film of 8-mm thickness was prepared on graphite using a hot-wall-type CVD technique. The ZnS thick film was then hot isostatically pressed under different pressures (125–205 MPa) in an argon atmosphere. The effects of pressure were systematically studied in terms of crystallographic orientation, grain size, density, and transmittance during the HIP process. X-ray diffraction pattern analysis revealed that the preferred (111) orientation was well developed after a pressure of 80 MPa was applied during the HIP process. A high transmittance of 61.8% in HIPZnS was obtained under the optimal conditions (1010oC, 205MPa, 6 h) as compared with a range of approximately 10% for the CVD-ZnS thick film under a 550-nm wavelength. In addition, the main cause of the improvement in transmittance was determined to be the disappearance of the scattering factor due to grain growth and the increase in density.
High-strength low-alloy (HSLA) steels show excellent toughness when trace amounts of transition elements are added. In steels, prior austenite grain size (PAGS), which is often determined by the number of added elements, is a critical factor in determining the mechanical properties of the material. In this study, we used two etching methods to measure and compare the PAGS of specimens with bainitic HSLA steels having different Nb contents These two methods were nital etching and picric acid etching. Both methods confirmed that the sample with high Nb content exhibited smaller PAGS than its low Nb counterpart because of Nb’s ability to hinder austenite recrystallization at high temperatures. Although both etching approaches are beneficial to PAGS estimation, the picric acid etching method has the advantage of enabling observation of the interface containing Nb precipitate. By contrast, the nital etching method has the advantage of a very short etching time (5 s) in determining the PAGS, with the picric acid etching method being considerably longer (5 h).
The effects of different spray angles (90°, 85°, 80°) on the microstructure and mechanical properties of a Y2O3 coating layer prepared using the atmospheric plasma spray (APS) process were studied. The powders employed in this study had a spherical shape and included a cubic Y2O3 phase. The APS coating layer exhibited the same phase as the powders. Thickness values of the coating layers were 90°: 203.7 ± 8.5 μm, 85°: 196.4 ± 9.6 μm, and 80°: 208.8 ± 10.2 μm, and it was confirmed that the effect of the spray angle on the thickness was insignificant. The porosities were measured as 90°: 3.9 ± 0.85%, 85°: 11.4 ± 2.3%, and 80°: 12.7 ± 0.5%, and the surface roughness values were 90°: 5.9 ± 0.3 μm, 85°: 8.5 ± 1.1 μm, and 80°: 8.5 ± 0.4 μm. As the spray angle decreased, the porosity increased, but the surface roughness did not show a significant difference. Vickers hardness measurements revealed values of 90°: 369.2 ± 22.3, 85°: 315.8 ± 31.4, and 80°: 267.1 ± 45.1 HV. It was found that under the condition of a 90° angle with the lowest porosity exhibited the best hardness value. Based on the aforementioned results, an improved method for the APS Y2O3 coating layer was also discussed.
In this study, an AISI 316 L alloy was manufactured using a selective laser melting (SLM) process. The tensile and impact toughness properties of the SLM AISI 316 L alloy were examined. In addition, stress relieving heat treatment (650oC / 2 h) was performed on the as-built SLM alloy to investigate the effects of heat treatment on the mechanical properties. In the as-built SLM AISI 316 L alloy, cellular dendrite and molten pool structures were observed. Although the molten pool did not disappear following heat treatment, EBSD KAM analytical results confirmed that the fractions of the low- and high-angle boundaries decreased and increased, respectively. As the heat treatment was performed, the yield strength decreased, but the tensile strength and elongation increased only slightly. Impact toughness results revealed that the impact energy increased by 33.5% when heat treatment was applied. The deformation behavior of the SLM AISI 316 L alloy was also examined in relation to the microstructure through analyses of the tensile and impact fracture surfaces.
