소프트웨어 제작자들이 불법복제로부터 그들의 제품을 보호하기 위해 노력하는 것처럼 콘텐츠 제작자들도 사용자간 불법 콘텐츠 공유를 규제하기 위해 노력하고 있다. 본 연구는 이러한 시도가 과연 저작권자의 권익을 보호하고 그들의 수익을 극대화할 수 있는 근본적인 해결책이 될 수 있을 것인지에 대하여 경제적 측면에서 논의한다. 이를 위해 불법 콘텐츠 공유에 대한 규제가 제작자의 수익에 미치는 효과를 파악하기 위한 분석적 모형을 개발하고 규제와 비 규제하에서 콘텐츠 제작자의 수익극대화를 위한 최적 조건을 제시한다. 분석결과, 정품 콘텐츠와 불법 복제 콘텐츠간의 충분한 차별화가 어려운 경우에는 불법 복제의 규제가 긍정적인 효과를 줄 수 있으나 정품 콘텐츠와 불법 복제 콘텐츠 사이에 충분한 차별화가 가능한 경우에는 오히려 규제가 없는 경우에 저작권자의 수익이 극대화되는 것으로 나타났다.

Purpose: This study aimed to investigate the job stress level of call center workers and figure out its relation with cognitive emotion regulation strategies as a cognitive coping strategy. Methods: Data collection was conducted on 985 call center workers, working for K companies in Korea. ANOVA, t-test, Scheffe's test and multiple regression have been conducted for the data analysis using SAS 9.0 software. Results: The total job stress score of subjects ranges $Q_{25{\sim}49}$ (the lower 50%) whereas the score of job demand and job control ranges $Q_{50{\sim}74}$ (the upper 50%), and its sectional job stress level is high. Since job stress is the major factor affecting cognitive emotion regulation strategies, it is shown that when the job stress score gets higher, the score of positive cognitive emotion regulation strategies gets decreased but the score of negative cognitive emotion regulation strategies, increased. Conclusion: Based on the results of this study, it is necessary to develop and apply an effective stress easing method for call center workers which reduces negative cognitive emotion regulation strategies and increases positive ones.

The global market size of AI based SaMD for medical image in 2023 will be anticipated to reach around 620 billion won (518 million dollars). In order for Korean manufacturers to efficiently obtain CE marking for marketing in the EU countries, the paper is to introduce the recommendation and suggestion of how to reclassify SaMD based on classification rules of MDR because, after introducing the Regulation EU 2017/745, classification rules are quite modified and newly added compared to the Directive 93/42/EEC. In addition, the paper is to provide several rules of MDR that may be applicable to decide the classification of SaMD. Lastly, the paper is to examine and demonstrate various secondary data supported by qualitative data because the paper focuses on the suggestion and recommendation with a public trust on the basis of various secondary data conducted by the analysis of field data. In conclusion, the paper found that the previous classification of SaMD followed by the rule of MDD should be reclassified based on the Regulation EU 2017/745. Therefore, the suggestion and recommendation are useful for Korean manufacturers to comprehend the classification of SaMD for marketing in the EU countries.

In this work, we developed a real-time versatile advanced control and supervisory software for a personal computer control. This software, basically, has background and foreground tasks which are performed in parallel at real time. First, background tasks are composed of controls of various kinds, reports and input-ouput of signals etc, which are performed every sampling time. Second, foreground tasks are observation of operation conditions, data search, regulation of controllers and graphical design and display of processes, which are performed by users request. Additionally, this software has the functions of transporting data and composing distributed control systems, and all background tasks are composed of combination of unit function blocks.

For loads analysis of airplane, applicable regulation should be determined. Then, loads conditions are prepared from the regulation. Modeling for aerodynamic, mass, and structure are performed. Panel method is usually adopted for aircraft loads analysis to obtain air loads. The ARGON which is a multidisciplinary fixed wing aircraft design software co-developed by the KARI and TsAGI are used for loads analysis. The ARGON can be utilized for flutter and stress analysis as well as for flight and ground loads analysis. In this paper, flight loads analysis for wing structural design of the regional aircraft at the conceptual design phase are performed with the ARGON. FAR 25 is used for the regulation for the load analysis. Shear force, bending moment and torsion diagrams for the wing and shear force and hinge moment for the aileron are presented.

The safety problems of buses have been arisen due to the increasing of road traffic. Occupant injuries are always possible in the rollover accident and the frontal impact. Thus the structure of bus should have sufficient strength to protect passengers under accidental loads. ECE(Economic Commission for Europe) regulation No.66 prescribes that the superstructure of the vehicle shall be sufficient strength for passengers' surviving and the residual space shall be preserved in the passenger compartment during and after the standard rollover accident situation. Rollover test and simulation on a large-sized bus was completed according to the regulation. The coordinates of the points on the bus were measured by photogrammetry system. The rollover situation was revived by structural crashes simulation software, PAM-CRASH, and it was checked that the structure still complied with the requirements of residual space during rollover situation. The residual space was preserved during rollover, so it was proved that the structure of the investigated bus had much probability of survival in rollover accidents.

Spindle motor current is used to estimate the cutting force indirectly and control the feed rate for the cutting force regulation. The proposed algorithm is implemented to a DSP board based hardware for the industrial application. The software to make POP terminal communicate with the DSP board and POP server is coded under Windows 95 environment. Experiments under varying cutting conditions show that the DSP board recognizes the information of installed cutting tool and cutting conditions delivered from the POP server to use them for the proper control of the feed rate. The cutting force is regulated well during machining of tapered or stepped workpiece and circular shaped workpiece as well.

There are many power system simulation software tools for time-domain performance in power system. This paper reports the results of time-domain simulation for the Jeju Power system with a secondary voltage regulation (SVR) model, developed with both TSAT and PSCAD/EMTDC and evaluates them, which are commercial software tools used for digital simulation of power system. TSAT has not been yet verified because of deficient modelling of components in the time domain performance of KEPCO power system. But PSCAD/EMTDC has been enough verified in our system. So, we need to compare and evaluate TSAT with PSCAD/EMTDC in small power system like Jeju. This paper showed that the results simulated by both TSAT and PSCAD/EMTDC is very similar to each other, so TSAT is able to apply for our KEPCO large power system.

AI 기술이 고도화됨에 따라 국내외에서 AI 로봇에 대한 법적 지위 및 규제 문제, 로봇등록제의 필요성이 대두되고 있다. AI 로봇의 형태 및 활동범위는 더 이상 한 국가내에 놓여진 하드웨어에 머물지 않을 것이므로, AI 로봇에 대한 정의 및 규제는 소프트웨어를 포함시킨 포괄적 개념으로 확장되어야하며, 이들에 대한 정보도 국제적으로 각국 정부가 안전하게 관리하고 공유할 수 있는 형태로 정의되어야한다. 본 연구는 이러한 관점에서 'AI 로봇'을 하드웨어와 소프트웨어를 포괄하는 AI 법인이라는 개념으로 확장시키고, (가칭) Juridical AI Chain이라는 허가형 블록체인을 이용해 AI 법인 등록제를 운영하는 방안을 제시한다. 블록체인은 각국 정부기관들의 관리 및 공유가 가능한 분산형 공유 장부이므로, 블록체인 기반 등록제의 운영은 AI 로봇의 상용화가 초래할 범세계적 문제들에 효과적으로 대처할 수 있는 방안이 될 것이다.

냅스터 (Napster)에 의하여 파일공유 소프트(P2P)는 세계적으로 인터넷과 컴퓨터 산업지형을 뒤흔들었을 뿐만 아니라, 다른 한편으로는 사용자의 저작권 침해를 알면서 그 행위를 조장하였다고 하여 기여책임(寄與責仔)이 인정된 이래 인터넷 사용자와 저작권자 사이에는 심각한 법적분쟁이 시작되었다. 다만 다양한 용도로 사용되는 컴퓨터 프로그램에 대해서 그것을 위법하게 사용한 자에 대한 형사적 제재는 당연하지만, 프로그램 개발자는 그 제공행위가 통상의 개발행위의 범위 내라고 한다면 설령 그것이 악용될 것에 대한 미필적인식이 있다고 하여 형사적인 처벌을 해서는 안된다고 생각한다. 따라서 본 논문에서는 이러한 전제로부터 냅스터에서 촉발된 P2P에 관한 미국, 일본, 한국의 판례에 나타난 법적책임 비난의 근거가 이를 충족하는지를 다시 살펴보고자 한다. 이와 같은 고찰은 과학기술의 발전과 권리자의 효율적인 구제가 균형을 이루기 위해서도 반드시 필요하다고 본다.
