일반적으로 노동시장은 노동자와 고용주들로 구성되며, 이들은 복잡한 상호작용을 통해 노사관계를 형성한다 본 논문에서는 진화 에이전트들로 구성된 노동시장 모델 상에서 노동자들 또는 고용주들 사이에서 형성될 수 있는 전략적 연합을 적용하여 노동자와 고용주의 수적인 비율로 표현할 수 있는 직업밀집도와 직업집중도에 따른 행동 특성을 분석한다. 전략적 연합은 다중에이전트 환경에서 상호간의 이득을 보장하는 효과적인 방법이 될 수 있다. 진화 노동시장에서 노동자와 고용주들은 집단 내에서 자율적으로 연합을 형성하며 죄수의 딜레마게임으로 진행되는 거래에 참여한다. 실험결과, 에이전트들의 행동이 직업밀집도와 직업집중도에 따라 다르게 나타나며, 특히 전략적 연합이 허용될 경우 노동자와 고용주들이 보다 공격적인 형태로 노사거래에 참여함을 보여준다.

The purpose of this study is to present the technology value model based on profit approach and IITP practical guide for Ethernet network technology, which is the core technology of autonomous vehicles and connected cars in the hyper-connected industry. In-vehicle network, Ethernet technology, Ethernet port count, port pricing, and application data for technology assessment are sources of global market research organizations. The data on the company's COGS (Cost of Goods Sold), operating capital requirement, capital expenditure, and income statement data are used by the Bank of Korea's Business Analysis Report. According to the results of the study, the product market size was estimated to be US $470.3 billion and the technology market size was $52.1 billion over the seven years of economic life cycle of technology. The market value of the technology was estimated to be $260 million reflecting the possibility of entry into the market. In the case of the corporate management analysis report, the average value of the IITP and the top 25% were $0.7 million and $40.2 million, respectively. -27.8 million, and -73.6 million dollars respectively. This implies that government support for policy support is needed when conducting corporate R&D with high cost-to-sales ratio. The results of this study can be used as a reference for the evaluation of technology demand based ICT R&D technology in the industrial internet market in the fourth industrial revolution era.

Modern vehicles are evolving from manual to automatic driving. As the ratio of electrical equipment and software increases inside the vehicle, vehicles that support autonomous driving are becoming another open computer system that can communicate with the outside. The safety of the vehicle means the safety of both the passenger and the non-passenger. It is not clear whether the safety problem of ultimate autonomous vehicles can be solved by the current solution of computer systems related to fault tolerance and security. Autonomous vehicles should not be dangerous to people after they are released to the market, so it is necessary to proactively diagnose all the risks that can be predicted with current technology. This paper examines the current developments of autonomous vehicles and analyzes their dangers that threaten driving safety, as well as their countermeasures.

This study aims at presenting practical self regulation system for digital game, especially optimized to Korea through the comparative analysis of system at home and abroad. For this, this study conducted a comparative analysis about various countries adopted self regulation system, such as America, Japan, and European Union. We drew some implications on the Korean practical policy for the digital game. First, self regulation organization should be consisted of market-friendly form. Second, though self regulation organization is a autonomous system of market, the organization should take rights to regulate illegal case. This would be a good way not only to reduce unnecessary institutional regulations but also to take socially image of reliable media. Third, government should provide self regulation organizations financial assist. This policy means that the organizations make a role fairly and objectively.

As the international standardization of 5G element technologies (e.g., 5G vertical satellite, direct communication functions between 5G NR (New Radio)-based devices) required not only in 5G verticals but also in autonomous navigation services is currently underway, it is expected to be utilized for autonomous navigation services while utilizing the economic size advantages of the scale of international standard-based solutions through 3GPP international standardization of marine communication services related to autonomous navigation vessels. In order to establish the ecosystem of ICT convergence market related to autonomous navigation vessels and to preoccupy core communication technology based on international standards, it is necessary to develop digital communication systems and gateways that have global compatibility, (2) secure core element technology based on next generation communication, and (3) promote international standardization for internationalization of related technologies. For this, data analysis and standard technology should be developed through service analysis by distance. Currently, the requirements for the operation of autonomous navigation vessels can be classified into three categories.

With the rapid advance of autonomous driving technology, the related vehicle market is experiencing explosive growth, and it is anticipated that the era of fully autonomous vehicles will arrive in the near future. However, along with the development of autonomous driving technology, questions regarding its safety and reliability continue to be raised. Concerns among technology adopters are increasing due to media reports of accidents involving autonomous vehicles. To promote the improvement of the safety of autonomous vehicles, it is essential to analyze previous accident cases and identify their causes. Therefore, in this study, we aimed to analyze the factors influencing the severity of autonomous vehicle accidents using previous accident cases and related data. The data used for this research primarily comprised autonomous vehicle accident reports collected and distributed by the California Department of Motor Vehicles (CA DMV). Spatial information on accident locations and additional traffic data were also collected and utilized. Given that the primary data used in this study were accident reports, a Poisson regression analysis was conducted to model the expected number of accidents. The research results indicated that the severity of autonomous vehicle accidents increases in areas with low lighting, the presence of bicycle or bus-exclusive lanes, and a history of pedestrian and bicycle accidents. These findings are expected to serve as foundational data for the development of algorithms to enhance the safety of autonomous vehicles and promote the installation of related transportation infrastructure.

대부분의 수출자율규제실시국(輸出自律規制實施國)들은 총(總)쿼타의 일부를 개방(開放)쿼타로 할당하여 수출단가(輸出單價)와 비규제국(非規制國) 수출실적(輸出實績)에 비례하여 배분하는 2단계(二段階)쿼타배분제도(配分制度)를 택하고 있으며 이는 수출자율규제(輸出自律規制)에서 오는 수출소득(輸出所得)과 수출물량(輸出物量)의 감소를 수출시장다변화(輸出市場多邊化)를 통해 줄이려는 정책적(政策的) 노력(努力)으로 해석된다. 본고(本稿)는 부분균형분석(部分均衡分析)을 통해 비규제국(非規制國) 수출실적(輸出實績)을 개방(開放)쿼타의 배분기준(配分基準)으로 하는 2단계(二段階)쿼타배분제도(配分制度)가 기본(基本)쿼타에만 의존하는 단일(單一)쿼타배분제도(配分制度)보다 비규제국(非規制國) 수출물량(輸出物量)을 증가시키고 이에 따른 수출소득(輸出所得)의 변화는 비규제국(非規制國) 수입수요탄력성(輸入需要彈力性)에 의해 결정됨을 보인 반면 개방(開放)쿼타를 얻기 위한 기업의 경쟁행위가 비규제국(非規制國) 수출가격(輸出價格)을 한계생산비(限界生産費) 이하의 수준으로 하락시켜 자원배분(資源配分)의 비효율(非效率)을 초래할 수 있으며 이는 바로 GATT규정(規定)에 위배되는 덤핑사례(事例)를 유도할 수 있음을 보였다. 따라서 수출(輸出)쿼타배분제도(配分制度)를 운용함에 있어서 자원배분(資源配分)의 효율(效率)과 국제무역환경(國際貿易環境)에 미치는 영향 등을 충분히 고려해야 할 것이다.

Various studies have been conducted using microtraffic simulation (VISSIM) to analyze the safety of traffic flow when introducing autonomous vehicles. However, no studies have analyzed traffic safety in mixed traffic while considering the driving behavior of general vehicles as a parameter in VISSIM. Therefore, the aim of this study was to optimize the input variables of VISSIM for non-autonomous vehicles through genetic algorithms to obtain realistic behavior. A traffic safety analysis was then performed according to the penetration rate of autonomous vehicles. In a 640 meter section of US highway I-101, the number of conflicts was analyzed when the trailing vehicle was a non-autonomous vehicle. The total number of conflicts increased until the proportion of autonomous vehicles exceeded 20%, and the number of conflicts decreased continuously after exceeding 20%. The number of conflicts between non-autonomous vehicles and autonomous vehicles increased with proportions of autonomous vehicles of up to 60%. However, there was a limitation in that the driving behavior of autonomous vehicles was based on the results of the literature and did not represent actual driving behavior. Therefore, for a more accurate analysis, future studies should reflect the actual driving behavior of autonomous vehicles.
