We need various methods to develop MMORPG that is game genre which many users use among various game genre using Internet. Specially, to heighten efficiency of distributing work, Object-oriented language such as C++ is used and we need design techniques that can take advantage of enough object-oriented concept when making large-scale game. There is various pattern that can apply in software breakup design in GoF's design pattern for these design techniques. If you apply Observer pattern to Party System Design for forming community between game users, you can easily add new class and maintain system later. Party Play is one of the important system that is used to form game users' community in MMORPG games. The main point that must be considered in Party-Play-System is to divide evenly experience value and acquisition that is got by Party-Play among users according to each user's level. To implement Party Play System that consider maintenance of system, in this paper, we propose a method using GoF's Observer-Pattern, showing you that proposed method which has advantage to dynamic memory allocation and to virtual method call can be used usefully to change object to real time at program run and to add new class and to maintain system new.

In the German federal election in 2021, the Social Democrats returned to power by a narrow margin and the Green Party emerged as the biggest winner. The two political parties took the lead by proposing policies that met the expectations of the people in the policies of climate and environment, pandemic response and health, and labor and social security. The Merkel effect did not play a significant role in the election, and it is highly likely that it will lead to government policy after the formation of a coalition. While the class cleavage in voting behavior has weakened, the generational cleavage has grown relatively large. Older people showed more support for the two major parties, while younger people showed higher support for the Green Party and the FDP. If the generational cleavage continues, it can be linked to the growth of the Green Party and the FDP, the continued weakening of the two major parties and the emergence of other new parties. In addition, the regional cleavage between the former East and West Germany still remain, which will affect the direction of the AfD and the Left and combine with other political cleavages. The 2021 German federal election can be said to be an election that heralds the realignment of the political party system.

Chinese American Writer, Ha Jin has been writing exclusively about the life in his native Communist China. His stories and poems are almost all about the Chinese people so far. In addition, the distinctive Chinese flavour and the inexorably repressive image of China in his works present an 'Other' to the American culture. Such kind of Chineseness can also be found in Ha Jin's works and his career as a writer. The continued demand for knowledge of China, which is created by China's increasingly important role in the globalized economy, sustains the country's position as an Other for America. In his early four novels, Ha Jin portrays a totally repressive image of Communist China, an image of which functions perfectly as a form of otherness for his American readers. In Ha Jin's portrayal, the Chinese masses are subjected to the Communist authority through its bureaucracy and state-economy mechanism, as well as through the godlike image of Mao Zedong. They are to follow the Communist conscience and subscribe to unity-in-difference. Deviation from the one-party rule is intolerable. In each of the novels, Ha Jin presents a specific system of repression. In In the Pond, confrontation against Party authority is contained by a process of complicity. In Waiting, the Party's power is upheld through a system of surveillance in which people act as agents, resulting in a web of power which paralyses love. The Crazed illustrates a play of power by Party officials which, against the backdrop of the Tiananmen Square Massacre, is full of craze itself, driving people either out of sanity or out of the country. War Trash exposes the Communist power's repression to the extreme by presenting a case of dishonour in those whose life is debased as trash by the Party. The repressive image of China produced in these stories, which span over half a century, makes Ha Jin's China a perfect Other for the West. To sum up, Ha Jin's novels construct a repressive image of China. In his novels, Ha Jin exposes the working of repression in particular systems. Through these systems, he problematizes the notion of personal autonomy for Chinese people and proposes for his western/American readers a solution which eventually turns into a re-presentation of American hegemony.

This paper considers Japanese political interviews to integrate conversation and facial expression analysis. The behaviors of political leaders will be disclosed by analyzing questions and responses by using the turn-taking system in conversation analysis. Additionally, audiences who cannot understand verbal expressions alone will understand the psychology of political leaders by analyzing their facial expressions. Integral analyses promote understanding of the types of facial and verbal expressions of politicians and their effect on public opinion. Politicians have unique techniques to convince people. If people do not know these techniques and ways of various expressions, they will become confused, and politics may fall into populism as a result. To avoid this, a complete understanding of verbal and non-verbal behaviors is needed. This paper presents two analyses. The first analysis is a qualitative analysis that deals with Prime Minister Shinzō Abe and shows that differences between words and happy facial expressions occur. That result indicates that Abe expresses disgusted facial expressions when faced with the same question from an interviewer. The second is a quantitative multiple regression analysis where the dependent variables are six facial expressions: happy, sad, angry, surprised, scared, and disgusted. The independent variable is when politicians have a threat to face. Political interviews that directly inform audiences are used as a tool by politicians. Those interviews play an important role in modelling public opinion. The audience watches political interviews, and these mold support to the party. Watching political interviews contributes to the decision to support the political party when they vote in a coming election.

Nowadays, nations cyber security capabilities play an important role in a nation's defense. Security-critical infrastructures such as national defenses, public services, and financial services are now exposed to Advanced Persistent Threats (APT) and their resistance to such attacks effects the nations stability. Currently Cyber Threat Intelligence (CTI) is widely used by organizations to mitigate and deter APT for its ability to proactively protect their assets by using evidence-based knowledge. The evidence-based knowledge information can be exchanged among organizations and used by the receiving party to strengthen their cyber security management. This paper will discuss on the business process reengineering of the CTI information exchange management for a nationwide scaled control and governance by the government to better protect their national information security assets.

We build middleware architecture with J2EE and LiveGraph to process different ubiquitous healthcare application's data and process that data into useful information, which can play a most important role in decision making in ubiquitous Healthcare System. Application developers mostly rely on third party middleware, tools and libraries (i.e., webservers, distributed middleware such as CORBA, etc.) to respond the emerging trends of their target domain. With this middleware we tried to enhance the efficiency of application by decrease their memory uses, data processing and decision making on another web module which is independent of each application. For middleware system, we proposed an algorithm by which we can find some important conclusion about different health status likewise ECG, Accelerometer. etc., which can be used in various data processing and determine the current health status. In this paper we also analyze some different low level and high level middleware technology which were used to build different kind middleware likewise CAMUS, MiLAN and try to find the best solution in the form of middleware for Ubiquitous Healthcare Information System.

Currently, most of the mobile game market releases games through Google play and App Store, which have a high share. Because it uses a third-party platform, only the payment API system provided must be used, and third-party platform pays the game company after excluding certain fees. Because game companies do not know whether or not to refund items and cannot get back items through third party transactions, users and professional websites are continuously appearing that exploit refunds. In this thesis, after analyzing problems of existing payment method and presenting a payment model using blockchain smart contract, we analyzed differences from existing model in terms of transparency, decentralization(fee), efficiency, and as a result, payment model using smart contract has low commission through P2P transaction without third parties and transparent transaction record, preventing item forgery and refund. Later, the proposed payment model would lead to the culling of companies acting on behalf of refunds for words that deviate from moral ethics such as "Refund OK even with items" and resolve the problem of unreasonable fees that arise through third-party platforms.

Damage and attack size of cyber terror is growing to the national size. Not only targeting at a certain companies or individuals but number of cyber terror targeting government bodies or unspecific people is increasing. This is because compared to traditional weapon, input cost is very cheap but ripple effect and shock are much stronger, affecting not only certain groups but also each individuals. 'Anti-terror measurement for protection of nation and public safety' passed last month is one of the renowned measurement passed regardless of objection from opposition party. The opposition party went against this through filibuster for 192 hours but this finally passed National Congress due to lack of oppositions. Korean government is taking post actions after passage of anti-terror measurement. Legislation of enforcement ordinance and regulations is due by 6th of next month. This regulation will be executed from June 4th after legislation. Whenever there is any security issues such as hacking of Korea Hydro and Nuclear Power and National Intelligence Service happens, lot of attention is made to those hackers. However, social recognition or management of those hackers need lot more improvement. Especially, as market of internet of things is increasing, there is an increased anxiety on information security. But as we only rely on security solutions, this problems are keep happening. Therefore, active investment on nurturing hackers who play the role of 'spear and shield' shall be made. Government should put more efforts to allow white hackers to show their abilities. We should have a policy for supporting high-quality programs such as BoB. To make information protection industry into future growth engine, it is necessary to nurture professionals for information protection and white hackers through special programs. Politicians should make related regulations as soon as possible to remove factors that prevent swift management of cyber attack due to lack of legislation. Government should pay lot more financial investment to nurturing professional manpower than now. Protecting life and asset of nation is responsibility and duty of our government. We all should recognize that controlling cyber attack is a part of national defense.

A prerequisite for a lasting ceasefire is the emergence of a prevailing view in Moscow and Kyiv that the fighting has reached a hurting stalemate. In sum, they both lose more through continuing warfare than by a ceasefire. This study applies social identity dynamics of nationalism to this escalatory conflict. It generates findings that imply that China as a third-party great power intervening mediator can potentially play a pivotal role. Shifting the respective prevailing views in Moscow and Kyiv of their interaction from a zero-sum foundation requires proffering powerful economic and political third-party incentives. Effective inducement would facilitate national defense, development and prestige for Moscow as well as Kyiv. China arguably has the underutilized potential power capabilities necessary to alter the respective prevailing views of strategic relationships among the great powers within Moscow, Brussels and Washington. A prerequisite for success in striving effectively towards this strategic goal is cooperation with the Beijing despite skepticism from Washington. This study utilizes a process tracing methodological approach. It highlights that the foundations of the Russo-Ukraine war lie in the institutionalization within Euro-Atlantic integration of the Cold War assumption that the USSR was an imperialist revisionist actor. Russia is the USSR's successor state. Moscow's prevailing view is that Russian national self-determination was unjustly circumscribed in the multinational Soviet totalitarian Communist system. The Euro-Atlantic community is perceived as a neocolonial imperial threat by allying with post-1991 Ukrainian nationalism at Russia's expense. The study finds that acknowledging Eurasian regional multipolarity is necessary, if not sufficient, to coopt Beijing into a global political stabilization strategy. It functionally aims to promote international balancing to lessen potentials for horizontal as well as vertical escalation of the Russo-Ukrainian conflict.
