The exploitation of the natural resources of the Moon and other celestial bodies represents one of the most exiting future developments in the field of space law as well as a unique occasion for the economic and social growth of mankind as a whole. The large number of benefits that are expected to be generated from the exploitation of these resources, indeed, not only will contribute to the betterment of conditions of people on Earth but also will allow mankind to face and likely solve one of the biggest problems currently affecting our planet, namely the exhaustion of the stocks of raw materials and other source of energy, such as fossil fuels. The exploitation of the natural resources of the Moon and other celestial bodies, however, has been prevented so far by the absence of dedicated space law rules allowing its orderly and peaceful development and clarifying the rights and duties of the parties involved in it. Due to the uncertainty generated by the absence of these rules, indeed, States as well as private operators have refrained from investing in the exploitation of space resources so far. The time to change this situation and to allow the exploitation of extraterrestrial resources to begin has finally come. This paper aims at fulfilling this purpose by proposing a legal regime containing specific and detailed rules to regulate the exploitation of the natural resources of the Moon and other celestial bodies.

In the present experimental study, the regime limit and pressure drop of dry-plug flow (dry wall condition at the gas portions of plug flow) in round mini-channels has been investigated. The air-water mixture was flowed through the round mini-channels made of Teflon, where the tube diameters ranged from 1.26 to 2.06 mm. For the present experimental range, with decreasing of the tube diameter, the transition between the plug and slug flows (wet and dry) happened at the higher gas superficial velocity region, which were in good agreement with the previous flow pattern maps tested. On the other hand, the transition between the wet- and dry-plug flows was little affected by the change of the tube diameter. In the pressure drop of dry-plug flows, among the correlations tested, the Lee and Lee's (2008) correlation best fitted the measured pressure drop data within the mean deviation of 10% for the present experimental range.

Whether a ship is sub-standard or not shall be finally decided by the minimum standards laid down in international conventions or national standards having the same effects. The flag State is primarily responsible for implementing these standards as far as its own ships are concerned. And the port State shall, in the exercise of its rights under international law, take appropriate measures (including detention of ships identified as sub-standard), which are regarded as port State's supplementary role aiming at implementing these standards. The international standards are implemented by the regional co-operation in the form of the MOU(Memorandum of Understanding) on Port State Control in the Asia-Pacific Region on the ground that the PSC enforcement of only one country does not enable the eradication of sub-standard ships. Recently, EQUASIS which is an international database covering the whole world fleet change the regionalism of PSC into the globalization of PSC. However, there are many problems in Tokyo MOV and Korean PSC regime. In order to ensure the implementation of the standards laid down in international conventions and Tokyo MOU, the Korean and other country in Asia-Pacific shall settle the alienation from the actuality of the law, namely the problem of maritime administrative structure of non unifying PSC affairs.

This analysis suggests a post Keynesian macro-dynamic model that integrates a financial variable, firm's debt, into the post Keynesian model of growth and distribution. On the basis of it, this study analyzes the effects of government financial expenditure on capital accumulation empirically. It also studies empirically whether a regime shift has arisen since Asian financial crisis in 1997. This paper shows that government financial expenditure has exerted an positive effect on capital accumulation. This empirical result supports government intervention in financial market in recurrence of financial crises. This study also finds grounds for a change in accumulation regime since Asian financial crisis in 1997.

The agricultural policy of Kim Jong-un's regime inherits the economic reform policy of the Kim Jong-Il period, which expands the autonomy of production and allows the market to dispose of products. The formation of markets represents an important factor in the business environment, as it indicates the establishment of fundamental conditions for management. However, major crops are still mainly managed by the state, and the government implements agricultural policies, such as emphasizing "Juche Farming." This study analyzed the impact of transition economic policies during the Kim Jong-un period on agricultural production using variability. Production variabilities increased for minor grain crops compared to previous years, but those of major grain (rice and maize) and horticultural crops did not change significantly. Even the production quantity of horticultural crops decreased, which is different from previous predicts that the expansion of the North Korean market would increase the consumption power of North Koreans and promote horticultural crop production. This study underscores the imperative for North Korea to develop policies aimed at stabilizing crop yields in the face of production variability. It proposes the establishment of an agricultural early warning system as a feasible solution to enhance agricultural infrastructure and promote inter-Korean cooperation.

The present study has focused on the environmental changes and evidences for sedimentation in the Lake Khuvsgul catchment during the Holocene period, inferred from short core sediment (BO03) from the eastern shore of Borsog Bay, which were analyzed in order to review records of the Holocene climatic evolution and Holocene history in Northern Mongolia. For the purpose of reconstruction of natural phenomenon that occurred in the lake catchment system during the Holocene, physical and chemical properties including HCl-soluble material, biogenic silica, organic matter and grain size distribution of minerals in the core sediments have been analyzed in this study. The vertical variations in composition for these properties show distinctly that five lines of paleoenvironmental evidence occurred in the lake catchment during the Holocene. A modified age model resulting from AMS carbon dating for the BO03 core sediment shows timings of these environmental events at 9.5 Kyr BP, 8.0 Kyr BP, 5.6 Kyr BP and 3.2 Kyr BP, respectively. Paleoenvironmental changes in the Lake Khuvsgul catchment system during the Holocene highlight distinctive features of the hydrological regime and geomorphologic evolution in the lake catchment due to regional landscape and global climatic changes corresponding with the Holocene optimum and thermal optimum. In particular, the change of hydrologic regime based on the sedimentological evidence has been caused by not only overland flow due to melting water, but also base flow due to thick permafrost around Khuvsgul region.

Rapid development in the upper reaches of the Mekong River, in the form of construction of large hydropower dams and reservoirs, large irrigation schemes, and rapid urban development, is putting water resources under stress. Many scientific reports have pointed out that cascade dams along the Mekong River lead to serious problems: not only hydrologically but also a decline of agricultural productivity due to a decrease of sediment supply in the Mekong Delta and a change of fish amount due to drastic change of the water environment. Cambodia and Vietnam, located in the lowest Mekong basin, are gravely affected by radical changes of hydrologic regime due to Mekong River developments. In particular, the Tonle Sap Lake in Cambodia is very sensitive to the flood cycle and flow variation of the Mekong River as well as inflow water quality from the Mekong River. More than 50% of Cambodian GDP depends on the primary industries such as agriculture, fishing, and forestry, and the Tonle Sap Lake plays an important role to support the national economy in Cambodia. In addition, Cambodian people usually take nourishment from the fish of Tonle Sap Lake. This research aims to assess the impacts of the Mekong river flow alternation on the hydrologic regime of the Mekong River - Tonle Sap Lake. We carried out rainfall-runoff-inundation simulation using CAESER-LISFLOOD for integrated water resource management in the Tonle Sap Basin and then analyze flood inundation variation of the Tonle Sap Lake due to the scenarios. Furthermore, the simulated inundation maps were compared to MODIS satellite images for model verification and hydrologic prediction.

In modern Spanish culture, there is not other cineaste who has explored the controversial topic of sexuality deeper and more reiterative ways than Pedro $Almod{\acute{o}}var$. In our opinion, $Educaci{\acute{o}}n$> fundamentally, is a metaphoric work about the corruption of the Catholicism during Francisco Franco regime in Spain. This movie is a brilliant and solid critic to the abuses suffered by a child in a religious school during the Franco regime. This movie is about the forbidden desire in Catholicism and the tragic end of a priest. Father Manolo sexually abused one of his students at the school; as a result, this student loses his sexual identity and ends up ruining his own life due to using drugs. Eventually he is revenged by his younger brother. On this movie, $Educaci{\acute{o}}n$>, Pedro $Almod{\acute{o}}var$ portrays a sentiment of anticlericalism and blasphemy against God and Jesus Christ through a story which contains homosexual scenes and direct quotations of biblical cites, such as the expulsion of the merchants and sellers out of the temple in Jerusalem in the Mathew gospel to insinuate Jesus'lack of charity and love to others. We conclude that Almodovar's description of the fallout of this priest, caused by his forbidden desire, is not only beyond anti-Catholicism but it can also be seen as an actual reflection of the cultural and sexual change in the European and, in particular, Spanish society.

The seasonal patterns of sediment supply were investigated during the period of June 1999 to June 2000 on a coastal foredune of Seungbong Island, Korea. Sediment supply was determined from measurements of geomorphic changes in the foredune and beach along six lines. Most sands were deposited on the dunefoot and foredune area during the winter and spring, from November to April. The largest amount of sands was deposited along the lines 5 and 6 near the sea-dike in the southern tip of the dune area. In general, the sand on the beach was gradually eroded in spring, summer and fall but deposited in winter. Total sediment accumulation over the study period was $484m^3$ for the foredune and $345m^3$ for the beach. The volume of the foredune increased in the winter and spring, whereas the volume of beach increased in the winter. Variation in sediment deposition appears to be controlled primarily by variations in the seasonal wind regime.

The decrease in the fracture toughness of ferritic steels in a reactor pressure vessel is an important factor in determining the lifetime of a nuclear power plant. A surveillance program has been in place in Korea since 1979 to assess the structural integrity of RPV steels. In this work, the surveillance data were collected and analyzed statistically in order to derive the empirical relationship between the embrittlement and strengthening of irradiated reactor pressure vessel steels. There was a linear relationship between the yield strength change and the transition temperature shift change at 41 J due to irradiation. The proportional coefficient was about $0.5^{\circ}C$/MPa in the base metals (plate/forgings). The upper shelf energy decrease ratio was non-linearly proportional to the yield strength change, and most of the data lay along the trend curve of the US results. The transition regime temperature interval, ${\Delta}T_T$, was less than the US data. The overall change from irradiation was very similar to the US results. It is expected that the results of this study will be applied to basic research on the multiscale modeling of the irradiation embrittlement of RPV materials in Korea.
