"United Nations Convention on Contracts for the International Carriage of Goods Wholly or Partly by Sea" was passed in July 3, 2008. on September 23, 2009 signing ceremony was held in Rotterdam. The system of maritime performing party is a special system in the transport convention, and constitutes an integral part of the Convention. Maritime performing party system is not the first system which brings in the carrier's independent contractor, but it is the most comprehensive and thorough one. It unified the duty of carrier's independent contractor in the maritime segment, and it is also an important progress in the developing process of international maritime legal system. There are some differences between the maritime performing party and China's current related system, i.e, the port maritime performing party and the intermediate performing party are included in the maritime performing party, and they can enjoy the carrier's exception clause and limitation of liability.

This paper aims to explain why severe political conflicts and confrontation between the ruling and opposition forces have been continuously caused, focusing on the institutional combination of presidentialism and the two-party system with strong party disciplines, after democratization in South Korea. And this also presents the US as a case in which presidentialism and a two-party system with weak party disciplines were combined once, and the Chile as another case in which presidentialism and a multi-party system with strong party disciplines is combined, respectively, and further analyzes how the chance of consensual politics could be raised in both the countries. In addition, this study suggests a practical implication that, in South Korea also, the political reforms for changes in party system such as the decentralization or democratization in party organizations to enhance the autonomy of individual legislators, or the introduction of runoff system in presidential elections or proportional representation system in parliamentary elections to product a multi-party system, are required for a high chance of consensual politics.

In this paper, we develop real-time monitoring system to detect third-party damage on natural gas pipeline by using sound propagation model. Since many third-party incidents cause damage that does not lead to immediate rupture but can grow with time, the developed real-time monitoring system can execute a significant role in reducing many third-party damage incidents. The developed system is composed of three steps as follows: i) DSP based system, ii) wireless communication system, iii) the calculation and monitoring software to detect the position of third-party damage using the propagation speed of acoustic wave. Furthermore, the developed system was set at practical offshore pipeline between two islands in Korea and it has been operating in real time.

The Rules of the Workers' Party of Korea (WPK), revised at the eighth Party Congress in 2021, reflect the Kim Jong Un regime's changes in strategic lines and ideological justifications on North Korea's socialism and communism, and its recent stances against the external environment. Moreover, they contain critical changes in the party's organizational system encompassing the central and the provinces. This study explores the organizational changes of the "monolithic guidance system of the party core" stipulated by the new party rules in January 2021, based on the analysis of the entire nine revised rules of the WPK since 1945. In the 2021 Party Congress, the Kim Jong Un regime, which officially came to power after the fourth Party Conference in 2012, has institutionalized the monolithic guidance system centered on the party core, or the head of state, Kim Jong Un. The newly set leadership and execution system, which reorganized party, government, and military organizational structure and accompanied the relevant personnel changes, was derived from the attempts for reinstating the Kim Jong Un regime as a more normalized party-state structure before its 10th year in power in April 2022. The "monolithic leadership system of the party core" established a system of "organizational leadership" through the organization of the Central Committee, directed by the Party Head, or General Secretary. The institutionalization of the new system resulted from the ten-year development of the revival of the party-state structure, which compromised the status of the military and reconfirmed the party's control of the military. This study explains the new system from the perspectives of both institutionalization and top-down unity, shedding light on the new party-military-government relations of the Kim Jong Un regime. The analysis contributes to a better understanding and forecasting of the Kim Jong Un regime's governance, which currently strengthens the monolithic leadership system as a crisis management system in the face of the "triple hardships" of sanctions, Covid and disaster.

What motivates split-ticket voting in mixed electoral systems, where voters choose one party in district races and another party on the party list ballot? While much of the literature assumes strategic intent, three aspects commonly are overlooked: the competitiveness of district races, the presence of a district candidate from one's preferred party, and whether voters know the electoral threshold for party list seats. Furthermore, few studies disaggregate types of split-ticket voting (e.g. not voting for one's preferred party in a district vs. party list). Taiwan provides an intriguing case study for analysis, not only as a relatively new adopter of a mixed system, but also the presence of additional conditions that would encourage at least the consideration of a split ticket. Using survey data from the Taiwan's Election and Democratization Studies (TEDS) after the Taiwan's 2016 Legislative Yuan election, this analysis finds that knowing the threshold, the winner's margin, and the placement of a district candidate from one's preferred party all influence split-ticket voting among those with a partisan preference. However, closer inspection identifies a distinction between defecting from the district versus the party list. Evidence shows that district competitiveness and candidate placement influences defection from the district candidate, while the electoral threshold influences defection from the party list. The results add to our understanding of strategic and non-strategic incentives in mixed systems.

Based upon the analysis of the former paper, this paper suggest that present problems existing in China's relevant laws and regulations, the difficulties in constructing China's maritime performing party system, the strategy in constructing maritime performing party in China. The writer focused on the strategies of establishing maritime performing party in China, and analyzed the problems which needed to pay attention. Finally, in the writer's view, China does not need to take part in the Convention, and can establish the maritime performing system by amending China Maritime Code.

Ahead of the 21st Korean National Assembly Election, the congressional election law was revised, and the semi-mixed member proportional system was introduced. The purpose of the revision of the election law was to increase the proportionality and representativeness of the election system through the institutional reform in the direction of promoting a multi-party system. This study shows that the effect of the introduction of the semi-mixed proportional system was compared with the election results when the previous proportional representative system was maintained. There was no significant difference from the results. This study reveals that contrary to the intention of institutional design to revitalize the multi-party system, the two large political parties took the most seats after democratization in 1987, resulting in an unintended consequences. In addition, with regard to the recent argument for party realignment, the Busan, Ulsan, and Gyeongnam regions have been dealigned in the Yeongnam regional cleavage, and are undergoing a process of party realignment. It has not yet entered the stage of realignment, but remains in the stage of fluid dealignment.

We consider a privacy-preserving cooperative computation protocol evaluating a beneficial function of all participants' secret inputs, such that each party finally holds a share of the function output. We propose a practical privacy-preserving cooperative computation protocol for solving the linear system of equations problem md the linear least-squares problem. Solutions to these problems are widely used in many areas such as banking, manufacturing, and telecommunications. Our multi-party protocol is an efficiently extended version of the previous two-party model.

In this paper, we develop a real time monitoring system to detect third-party damage on natural gas pipeline. When the damage due to third-party incidents causes an immediate rupture, the developed on-line monitoring system can help reducing the sequences of event at once. Moreover, since many third-party incidents cause damage that does not lead to immediate rupture but can grow with time, the developed on-line monitoring system can execute a significant role in reducing many third-party damage incidents. Also, when the damage is given at a point on natural gas pipeline, the acoustic wave is propagated very fast about 421.3 m/s. Therefore, the data processing time should be very short in order to detect precisely the impact position. Generally, the pipeline is laid under ground or sea and the length is very long. So a wireless data communication method is recommendable and the sensing positions are limited by laid circumstance and setting cost of sensors. The calculation and monitoring software is developed by an algorithm using the propagation speed of acoustic wave and data base system based on wireless communication and DSP systems. The developed monitoring system is examined by field testing at Balan pilot plant, KOGAS being done in order to demonstrate its validity through reactive detection of third-party contact with pipelines. Furthermore, the development system was set at the practical pipelines such as an offshore pipeline between two islands Yul-Do and Youngjong-Do, and a land branch of Pyoungtaek, Korea and it has been operating in real time.

How do party organizations respond to newly evolving social groups? Research on Indian party organizations reveals that in multiethnic societies with uneven modernization between social groups, internally competitive parties respond better to newly evolving groups. Moreover, it is claimed: the same dynamic works vis-$\grave{a}$-vis homogenous societies with cleavages based on economic differences; and, the pattern holds regardless of differences in electoral institutions. This study examines these claims by testing whether factional competition correlated with recruitment into Japan's Liberal Democratic Party in 1972 and 1983. Japan had a single-nontransferable-vote system with multi-member districts, while the research on India assumes a first-past-the-post system with single-member districts. This study conducts a difference of means test on the population of new and old politicians in the LDP in 1972 and 1983 with a pooled variance adjustment to account for differences in populations' size. The findings show that intra-party competition and recruitment are not correlated in Japan, thus tentatively rejecting both claims.
