In the era of low growth, many provincial cities are experiencing population decline and aging. Population decline phenomena such as reduction of productive manpower, reduction of finances, deterioration of quality of life, and collapse of the community base are occurring in a chain and are being pushed to the brink of extinction of the cities. This study aims to propose a methodology to objectively estimate the employment creation centers and setting the basic unit of industrial-centered zoning by applying spatial statistical techniques and GIS for the application of the compact city plan as an efficient spatial management policy in a city with a declining population. In details, based on reviewing previous studies on compact city, 'employment complex index(ECI)' were defined considering the number of workers, the number of settlers, and the area of development land, the employment creation center was estimated by applying the 'Local Moran's I' and 'Getis-Ord's Hot-Spot Analysis'. As a case study, changes in the four years of 2013, 2015, 2017, and 2019 were compared and analyzed for Changwon City. As a result, it was confirmed that the employment creation center is becoming compacted and polycentric, which is a significant result that reflects the actual situation well. This results provide the basic data for functional and institutional territorial governance for the regional revitalization platform, and provide meaningful information necessary for spatial policy decision-making, such as population reduction, regional gross domestic product, and public facility arrangement that can respond to energy savings, transportation plans, and medical and health plans.

Purpose - This study examines the influencing factors of China's cross-border e-commerce exports in the context of the current situation and trends of China's cross-border e-commerce development. Through an improved trade gravity model, it provides more in-depth research and constructive opinions on the development of cross-border e-commerce in China. In this paper, factors such as consumption gap, volume of trade frictions, number of tourists, Internet usage and trade openness are added to the formula of the traditional trade gravity model in the improved trade gravity model to examine the influencing factors on China's cross-border e-commerce exports. Design/methodology - According to the empirical analysis, China's cross-border e-commerce exports to ten countries are used as dependent variables, and consumption gap, trade friction volume, trade distance, trade openness and number of Internet users are taken as independent variables. Regression analysis is conducted through a modified gravity model to test whether the hypotheses hold. Findings - The analysis shows that the hypothesis that China's cross-border e-commerce exports are influenced by trade openness, trade distance, consumption gap between trade parties, and the number of Internet users in the importing country is supported by these four hypotheses, but not all independent variables have an impact on them. Specifically, the number of travelers, trade frictions do not have an impact on China's cross-border e-commerce. That is to say, trade friction between China and the United States and political issues such as China-India and China-Japan territorial disputes that emerged before do not affect the development of cross-border e-commerce in China. Originality/value - The analysis shows that the factors influencing China's cross-border e-commerce exports are the trade openness of the importing country, the trade distance, the number of Internet users in the importing country, and the consumption gap between the two sides of the trade. The trade openness and the number of Internet users positively contribute to China's cross-border e-commerce, while the consumption gap and trade distance are negatively related to them. And the analysis found that the Sino-US trade war and the Sino-Indian territorial disputes and other trade frictions to China's cross-border e-commerce exports did not have a substantial impact.

In Korean context, the innovative cities imply new towns or urban clusters in the Non Capital Regions, all of which would accommodate the relocated Capital based public organizations. The central government-initiated innovative cities have provoked pros and cons towards their effectiveness and efficacy for the balanced territorial development. From a broader prospective, this paper firstly examines the current status quo of the innovative cities. Based on their master plans, it analyzes physical and non physical factors which would exert significant impact on the innovative cities. Secondly, it pays attention to how key factors strengthen or weaken their behavioral patterns in terms of dynamic location and implementation policies of the innovative cities. Using System dynamics approaches, it sets up couples of scenarios, categorizing between supporting and opposing arguments towards the innovative cities. Lastly, after divulging systematic structure of the innovative cities, it proposes a series of practical alternatives which would contribute to minimizing unexpected side effects or unwanted social cost in the long run. In order to guarantee reinforcing structure of the innovative cities, the paper suggests that QOL (quality of life) variables, which would require continuous investment in the social infrastructure, are pivotal in achieving original goals of the innovative cities. Otherwise, the innovative cities would not be innovative per se. In the worst case, they might be degraded into the unpopular ghost towns.

The present study was undertaken to provide basic data on fetal endochondral ossification for the native Korean cattle femur. This study was determined to the both earliest stages of chondrification and ossification by histochemical methods. The forty-five pairs of femur, from a series of embryos and fetuses ranging from 11 to 100mm in crown-rump(C-R) length, were used. These samples were divided into 9 groups. The groupings were based on C-R length, as the first grouping being 11~20mm, the second grouping being 21~30mm and so on. The results were as follows: 1. Alcianophility and PAS reaction were markedly increased in the perichondrium and interterritorial matrix in the 3rd group(C-R length 31~40mm). These reactions were decreased in the territorial matrix and in the adjacent area to the cartilage canal in the 5th group(C-R length 51~60mm). 2. Calcium deposits and collagen substances were observed initially in the 3rd group(C-R length 31~40mm). The calcium deposits and calcified cores were observed in the trabeculae of the proximal epiphyseal plate of the femur in the 8th group(C-R length 81~90mm).

The Antarctica continent does not belong to any countries so that a place in the region has some different place names between countries. Korea gave Korean place names to the places around the King Sejong Station, and the names have since been used by Korean researchers on the Antarctic. However, they have yet to be registered officially at CGA(Composite Gazetteer of Antarctica) by November 2010. Therefore, to prepare for the possible disputes over territorial claims in Antarctica and to expand and specify activity areas, this research tries to analyze the present condition of advanced countries' committees on place names of Antarctica, their procedures of registering names and their registration criteria, and thereby suggest an efficient plan for registering place names of Antarctica. If the plan suggested in this research is actively reviewed and applied, it will be able to make a great contribution to advancing the place names of Antarctica and research on the Antarctic.

On 12 July 2016, China's maritime claim to most of the South China Sea (SCS) based on the so-called nine-dash line was rejected by the Arbitral Tribunal, constituted under Annex VII to the UN Convention on the Law of the Sea (UNCLOS) concerning issues in the South China Sea including the legality of the so-called "nine-dashed line", the status of certain maritime features and their corresponding maritime entitlements, together with the lawfulness of certain actions by China which the Philppines, in a case brought in 2013, alleged were violations. As having the Tribunal determined that China's claim had no legal grounds in UNCLOS, thus undermining China's claims, and establishing that China has no exclusive legal rights to control the area roughly the size of India. There are some major implications from the Tribunal's ruling in the Arbitration award. These include implications on: how to delimit the maritime boundary in disputed waters, how to promote maritime confidence-building measures, how to safeguard maritime safety and security, and how to promote the rule of law in the SCS. Since its application of UNCLOS in East Asia, it has been obvious that the only way to resolve maritime disputes in the region is to build strong maritime cooperative partnerships under the auspices of the rule of law.

In this paper, offshore wind resources within the Japan's EEZ (Exclusive Economic Zone) are assessed using wind speed data from the microwave scatterometer SeaWinds onboard QuikSCAT. At first, from the 10m-height wind speed from QuikSCAT, 60 m-height wind speed is estimated by using an empirical equation for height correction. Based on the 60 m-height wind speeds, annual energy Production is calculated under an assumption of installing 2 MW wind turbines every $0.64km^2$. The annual energy production is then accumulated for the entire Japan's territorial waters and EEZ ($4.47{\times}10^6km^2$). As a result, it is shown that the total energy Production is estimated to be $4.86{\times}10^4$ TWh/yr. This offshore wind energy Potential within the EEZ is approximately 50 times higher than the actual annual electricity production in Japan.

The purpose of this study is to fashion-design the image of Cleopatra on the basis of Cleopatra's characteristic, clothing and its symbolic meaning shown in movie . In movie , Cleopatra(69B.C-30B.C) is described as passionate, intelligent, dignified person and even as enchantress. Costume that Cleopatra wears compound the type of ancient Egyptian costume in New Kingdom, the change of it, and the trend in the 1960's. Their color and pattern also symbolizes religion by adding ancient Egyptian myths to show the absolute royal authority. Therefore, design concepts, determined on the base of Cleopatra's characteristic and symbol meaning, are applied to make creative costume with Cleopatra's image of God Isis. In order to show Cleopatra's dignity, confidence, territorial ambition, black is used as a general base color. To represend Cleopatra's passion and the image of Isis, red is used. And the word 'Kemeto' represents all these symbols. As a whole, dress named 'Kemeto of Cleopatra' is designed and created.

Although the uninhabitable islands are part of national property, those are not systematically managed and controlled in Korea. In this study, the positioning standards for uninhabitable islands are suggested with proper surveying methods. To establish the standards, the current status on managing the uninhabitable islands in foreign countries are investigated and analyzed. It was found that it is necessary to establish the ocean geodetic network based on a sound and systematic plan. In Korea, the ocean geodetic network can be established by combining the National control point and territorial sea control points. We suggested that one or two third or fourth control points are required to be established in total of 2,679 islands with connection to the 47and 249 first and second-order control points. It is expected that this network will provide ground control points for aerial and satellite images for large scale ocean mapping. In addition, close cooperation among the related departments such as Ministry of Construction & Transportation, National Geographic Information Institute, Ministry of Government Administration and Home Affairs, Ministry of Maritime Affairs and Fisheries, and Ministry of Environment is necessary for successful management on uninhabitable islands.
