As FTAs are introduced, greater trade between the countries results in more disputes between parties to the agreement. Disputes in international trade have previously been settled mainly through international arbitration. However, with the recent rise in negative aspects of the arbitration system, the international community has begun to seek ways to utilize mediation for replacing the arbitration system. Mediation is a dispute settlement system that helps the parties settle their disputes on their own through negotiations. The UNCITRAL, which seeks to unify and develop international trade law, amended the Model Mediation Law in 2018 and adopted the 'United Nations Convention on International Settlement Agreements Resulting from Mediation' in August 2019 to enable the adoption of the international settlement agreement. This study analyzes the main contents of the 2018 Model Mediation Law and predicts the potential for the development of international commercial mediation as a dispute settlement procedure for future international trade.

In this study, settlement characteristics of 38 CFRD was investigated from monitoring data and the method to estimate the dam settlements considering valley shape during constructions was proposed. The construction modulus of dam was found to be dependent on void ratios and valley shape factor. The construction modulus varied with valley shape and decreased with increasing void ratio. Also, the modulus was increased when the shape coefficient was less than 4. The settlement investigation results showed that the total settlement was proportional to the value of the settlement coefficient multiplied by the shape coefficient divided by void ratio.

This paper presents case history of railway embankment excess settlement on soft clay during service in southern region of Korea. A lot of field observations show that the measured settlements are a lot larger than settlements actually calculated in this area. Back analysis is carried out to verify the soil parameters which are intended to investigate in the subsurface exploration phase and later in a laboratory test program. Recommendations and causes for the engineering practice are suggested to review the determination of excess settlements and, consequently, to improve the settlement prediction. This enormous discrepancy is due to the passing over secondary consolidation, and the design filling did not meet to real construction filling. Immediate settlement could be subsidiary factor of excess settlement.

The settlement characteristics of refuse landfills are peculiar because considerable amount of settlement occurs due to the decomposition of refuse organic solids for very long period. The total amount of compression that occurs due to the decomposition in refuse landfill is mainly dependent on the amount of biodegradable refuse solids and fill Ige of the refuse landfill, and the settlement stabilization speed is dependent on the decomposition condition. In order to figure out the settlement characteristics of refuse landfills. a proposed mathematical model is applied to settlement data of refuse landfills with different fill ages. A data bank of model parameters was obtained and the trends were analyzed. The long-term settlement behavior of refuse landfills can be estimated fairly well by the proposed model. The total remaining amount of settlement may be predicted on the basis of the fill age and appropriate two design parameters.

Settlement of investment disputes is quite different from that of commercial disputes arising from ordinary commercial transactions in view of disputing parties, applicable laws and rules, etc.. Therefore, it is very important to consider the Convention on the Settlement of Investment Disputes between States and Nationals of Other States(Washington Convention) of 1965. The creation of the International Centre for Settlement of Investment Disputes(ICSID), which was established under the Washington Convention, was the belief that an institution specially designed to facilitate the settlement of investment disputes between governments and foreign investors could help to promote increased flows of international investment. Pursuant to the Washington Convention, ICSID provides facilities for the conciliation and arbitration of disputes between member countries and investors who qualify as nationals of other member countries. Recourse to ICSID conciliation and arbitration is entirely voluntary. However, once the parties have consented to arbitration under the Washington Convention, neither can unilaterally withdraw its consent. Moreover, all Contracting States of the Washington Convention are required by the Convention to recognize and enforce ICSID arbitral awards. Provisions on ICSID arbitration are commonly found in investment contracts between governments of member countries and investors from other member countries. Advance consents by governments to submit investment disputes to ICSID arbitration can also be found in many bilateral investment treaties including the Korea-China Agreement on the Encouragement and Reciprocal Protection of Investments(1992), the Korea-Japan Agreement for the Liberalization, Promotion and Protection of Investment(2003) and the Korea-Chile FTA, the latter was signed as of February 15, 2003 and is still pending in the National Assembly for its ratification. Arbitration under the auspices of ICSID is similarly one of the main mechanism for the settlement of investment disputes under the bilateral treaties on investment. Therefore, it is a problem of vital importance that Korean parties interested in investment to foreign countries should understand and cope with the settlement mechanism of investment disputes under the Washington Convention and bilateral investment treaties.

The objective of this research was to analyze the determinants of demand for residential settlements in rural societies. A significant aspect of the demand analysis was to consider depopulation classification as a moderating variable with a view to its role as an essential dividing factor of socioeconomic characteristics and physical environments of the areas of concern. The data collection for analysis was divided according to types of depopulation into the three categories of less developed, stagnated, and developed areas. For the cause and effect analysis between the residential demand and factors of settlement, the ordered probit model was applied. Significant determinants of settlement demand unfolded according to depopulation types. In the case of less developed areas, residential demand was affected significantly by the factors of daily life convenience and public facilities. Key settlement demand determinants of stagnated regions included the aspects of basic natural environment, daily life convenience and education. Meanwhile, key settlement demand determinants for developed areas included education and agriculture economic aspects. The importance-performance analysis was also applied to a set of settlement characteristics of rural communities to figure out the settlement factors requiring urgent endeavor to improve.

Recently in Korea, a marine ranching project has continued to grow with the increasing needs of sea development. Management techniques, including settlement reduction and scour protection, have been required for constructing and maintaining the artificial reefs of this marine ranching project. The generation of settlement and scour can be influenced by ground characteristics. In this study, various laboratory tests (penetration test, two-dimensional water tank test) were performed to determine the settlement and scour characteristics of artificial reefs under various ground conditions. Three kinds of ground reinforcement were prepared: unreinforced, geogrid, and hybrid bamboo mat. Penetration test results showed that the normalized settlement ratio of ground reinforced with a hybrid bamboo mat was smaller than those of unreinforced ground and geogrid-reinforced ground. Two-dimensional water tank test results showed that the scour characteristics of ground reinforced with a geogrid were more reduced and stable than unreinforced ground. The amount of scour and ground settlement also decreased with increasing reinforced area.

Tunnel boring machines combined with the earth pressure balanced shield method (EPB shield TBMs) have been adopted in urban areas as they allow excavation of tunnels with limited ground deformation through continuous and repetitive excavation and support. Nevertheless, the expansion of TBM construction requires much more minor and exquisitely controlled surface settlement to prevent economic loss. Several parametric studies controlling the tunnel's geometry, ground properties, and TBM operational factors assuming ordinary conditions for EPB shield TBM excavation have been conducted, but the impact of excessive excavation on the induced settlement has not been adequately studied. This study conducted a numerical evaluation of surface settlement induced by the ground loss from face imbalance, excessive excavation, and tail void grouting. The numerical model was constructed using FLAC3D and validated by comparing its result with the field data from literature. Then, parametric studies were conducted by controlling the ground stiffness, face pressure, tail void grouting pressure, and additional volume of muck discharge. As a result, the contribution of these operational factors to the surface settlement appeared differently depending on the ground stiffness. Except for the ground stiffness as the dominant factor, the order of variation of surface settlement was investigated, and the volume of additional muck discharge was found to be the largest, followed by the face pressure and tail void grouting pressure. The results from this study are expected to contribute to the development of settlement prediction models and understanding the surface settlement behavior induced by TBM excavation.

Settlement prediction has been conducted using Hyperbolic, Hoshino, and Monden methods, etc in the fields. These methods are only able to predict settlement after finishing the final filling stage. A new method is proposed to make up for such a weak point. This method was named as SPSFC (Settlement Prediction for Staged Filling Construction) method, which can be able to predict the settlement both the final filling stage and the staged filling from the initial filling stage in soft ground. To verify the applicability of the SPSFC method, firstly. The settlement predicted by the existed methods are compared with that obtained by the SPSFC method. The comparison results indicate the SPSFC has enough reliability to use for prediction of settlement. Secondly. by analyzing the settlement data measured during the initial filling stage, the soil parameters which need to predict the settlement are obtained by the SPSFC method. Then using the obtained soil parameters the time-settlement curve is predicted and compared. The predicted settlement is well matched with the measured one. From the study, the SPSFC method can be possible to predict settlement during the staged filling with only the initial settlement data.

In the case of the Pohang earthquake, which had a magnitude of 5.4 in 2017, geotechnical damages such as liquefaction and ground settlement occurred. The need for countermeasures has emerged, and experimental research in the Pohang area has continued. This study collected undisturbed samples from damaged fine-grained soil areas where ground settlement occurred in Pohang. Cyclic tri-axial tests for identifying the dynamic characteristics of soils were performed on the undisturbed samples, and the results were analyzed to determine the cause of ground settlement. As a result of the study, it was determined that in the case of fine-grained soils, ground settlement occurred because the seismic load as an external force was relatively more significant than the shear resistance of the very soft fine-grained soils, rather than due to an increase in excess pore water pressure.
