Incheon, South Korea, is a rapidly growing port city that has long held an important role in the country. While for most of its history it has been considered more of a coastal extension of Seoul, it is now trying to grow from that role and become a global city. National and local initiatives and acts have led to the Incheon Free Economic Zone (IFEZ). This large zone connects three smaller districts into one large project. The goal of the project is to assert Incheon as its own city and go beyond its role as merely a gateway to Seoul. However, as most large-scale projects go, there are multiple issues and constraints faced by the IFEZ. This paper analyzes the project and gives critique on how the project could possibly achieve its goal more quickly.

Since the term smart city was coined, theories and practices of smart cities have flourished. Regarding the theoretical aspect, user-driven innovation has been discussed in studies on the innovation ecosystems of smart cities. Smart cities have been built in various countries around the world in recent years, including in Japan, which has experienced the same global trends in smart cities since 2010. Four smart community projects run by the Agency for Natural Resources and Energy between 2010 and 2014 followed such trends. The present study addressed user-driven innovation using the quadruple helix model as an analytical framework for the four smart community projects, and the outcomes of the projects were evaluated. In conclusion, the smart community projects were evaluated as successful. However, it was revealed that these projects were not completely conducive to user-driven innovation.

Destination attributes represent the attractiveness of destinations that pull tourists to visit them. Destination marketers must understand what motivates tourists to choose certain destination attributes before they travel. Considering religious tourists plays an important aspect in influencing travel decisions, especially destination choices. For instance, the appearance of Islamic religious attributes in destinations can delight Muslim tourists and stimulate their satisfaction and loyalty. This study examines smart tourism city. In particular, it investigates the effects of Seoul's destination attributes on Muslim tourists' satisfaction and loyalty to South Korea. Results show that non-Islamic destination attributes (conventional attributes) have positive relationship with Muslim tourists' satisfaction, and their satisfaction is positively related to their loyalty toward South Korea as a travel destination.

본 연구는 Oxford Economics에서 제공하는 Global Cities Forecast 자료(2013)를 이용하여 한국의 7대 광역시를 포함한 전 세계 주요도시의 경쟁력지수 및 분배지수를 산출하고 그 종합순위를 정리하였다. 도시경쟁력지수는 규모지표, 비율지표, 성장률지표 등 총 18개 경제관련 지표를 선택하였고, 분배지수로서 지니계수를 이용하였다. 경쟁력지수와 지니계수 간의 관계를 분석하기 위하여 LOGIT 회귀모형을 이용하여 분석하였으며 추정결과 소득불평등(지니계수) 증가는 5년 시차로 볼 때 도시경쟁력지수 또한 경제성장률 변화에 음(-)의 영향을 미치고 있으며 통계적으로 유의하였다. 지니계수가 높을수록 도시경쟁력에 부정적으로 영향을 미친다는 추정결과에 따라 도시경쟁력지수에 분배지수를 포함시켜 총 19개 지표로 세계주요 도시 및 국내 7대 광역시의 글로벌 도시경쟁력 위상을 정리하였다. 2012년 실질가치 기준으로 계산된 서울의 도시 종합경쟁력 순위는 2010년 세계 59위, 2015년 세계 74위, 2030년에는 세계 185위로 급격히 하락하는 것으로 나타나고 있으며 나머지 6대 광역시의 종합경쟁력지수도 모두 하락하는 것으로 나타났다. 도시경쟁력 하락은 장기적으로 국가경쟁력 하락을 의미하므로 도시경쟁력 확보를 위한 문제점 진단과 전략적 방안의 강구가 절실히 요구된다.

Mogao Grottos are located at the eastern foot of the Mingsha Mountain, 25km southeast of Dunhuang City. The caves were excavated into the cliff on the west bank of the Daquan River. The wall paintings in the caves are subject to the severe deterioration generated by recrystallization of salt. It relates with the movement of water/moisture in rock formation. Through the satellite image analysis and geological survey it has been clarified that the movement of ground water is governed by the fault system. The geographical nature is specified by the aggressive tectonic movement from the south.

The purpose of this research is to review historical development of Islamic finance in individual East Asian economies, including China, Japan, South Korea and Hong Kong, and examine the success factors of the Hong Kong Sukuk issuances in 2014-2017. The research is a qualitative study applying case study method. It is found that the East Asian economies do play efforts to develop their Islamic capital markets although they have very limited size of Muslim population. Their progress on this development generally remains to be slow. The Hong Kong Sukuk is a breakthrough, carrying a total issuance value of US$3 billion. The Sukuk issuances, treated as a kind of asset-backed securities with restrictions on financing purposes, are distributed to international investors by investment banks from Hong Kong, Middle East and Malaysia. Success factors of these issuances include involvement of an issuer with high credit quality, recognition by central bank for using the Sukuk in its discount facility for commercial banks, centralized clearing services for the Sukuk and global banking network for underwriting the Sukuk. The lessons from the Hong Kong Sukuk are good references for other economies to develop their regional Islamic capital markets and to integrate the markets into the global capital market.

According to the 2012 social blue book released by the Chinese Academy of Social Sciences, China's urban population reached 50% in 2011. With the migration from marriage and new household registration, many urban collective assets have been formed in cities. Due to the unclear property rights and the emptiness of the main body, the distribution of collective assets mostly depends on the village cadres. The central government is preparing relevant laws and regulations to fill this legal gap, while the scheme of restructuring is decided by the villagers' vote, the local government coordinate the land acquisition and management. With the process of urbanization, a large number of second-generation of demolition studied abroad, which has attracted worldwide attention. In addition to the huge amount of compensation, due to the continuous rising of the land price, the value of the collective property and enterprises on the land also keep rising, the management agency of these assets is named village economic cooperative. This paper seeks to analyze the current status and future direction of these wealthy organizations, propose solutions to some existing problems.

This study analyzed a change trend of ambient temperature over the last sixty years in the largest industrial city in Korea, Ulsan. Linear warming rates in Ulsan over the last 25 (1985 to 2009), 40 (1970 to 2009), and 60 (1950 to 2009) years were 0.0507, 0.0416, and $0.0277^{\circ}C/yr$, respectively. The annual average temperature (AAT) and the annual average of the daily lowest temperature (AADLT) in Ulsan increased 1.3 and $2.9^{\circ}C$, respectively, over the last fifty years (1960 to 2009). The increasing slopes of the AAT and AADLT over the fifty years in Ulsan were higher or much higher than those in neighboring cities and on a global scale. In the comparison analysis of daily average temperature over the most recent ten years, the highest ($15.9^{\circ}C$) was observed in the industrial area followed by the downtown, coastal, suburban, and rural areas with 14.6, 14.5, 14.0, and $12.8^{\circ}C$, respectively. The number of cold days less than $5.0^{\circ}C$ decreased, while the number of hot days higher than $20.0^{\circ}C$ increased. The decreasing slopes in the cold days in lower latitude cities were steeper than those in higher latitude cities in Korea.

The ozone concentration is one of the important environmental issue for measurement of the atmospheric condition of the country. This study focuses on applying the Autoregressive Error (ARE) model for analyzing the ozone data at middle part of the Gyeonggi-Do, Anyang monitoring site in Korea. In the ARE model, eight meteorological variables and four pollution variables are used as the explanatory variables. The eight meteorological variables are daily maximum temperature, wind speed, amount of cloud, global radiation, relative humidity, rainfall, dew point temperature, and water vapor pressure. The four air pollution variables are sulfur dioxide $(SO_2)$, nitrogen dioxide $(NO_2)$, carbon monoxide (CO), and particulate matter 10 (PM10). The result shows that ARE models both overall and monthly data are suited for describing the oBone concentration. In the ARE model for overall ozone data, ozone concentration can be explained about 71% to by the PM10, global radiation and wind speed. Also the four types of ARE models for high level of ozone data (over 80 ppb) have been analyzed. In the best ARE model for high level of ozone data, ozone can be explained about 96% by the PM10, daliy maximum temperature, and cloud amount.
