By measuring error of resample ratio, we adjust the ratio to reduce the ratio error and find correct resampling positions. The error compensation is continuing from the start operation time. The proposed method enhances 30dB side lobe suppression and 1dB BER. We verify the method with behavioral model and HDL code.
인력교육에서 게이미피케이션의 한계와 역효과에 대한 관찰연구
김상균(Kim, Sangkyun) 한국게임학회 2015 한국게임학회 논문지 Vol.15 No.3
재미와 행복은 인간이 추구하는 본질적 가치이다. 게임은 그러한 본질적 가치를 만족시키는 매우 편리한 수단 중 하나이다. 그 수단을 교육에 접목하여, 재미있는 교육을 추구하는 시도들이 활성화되고 있다. 기업과 학교의 인력교육 현장에서 게임의 활용도가 증가하면서, 게임을 접목한 교육방식의 한계와 역효과에 대한 우려의 목소리도 생기고 있다. 역효과와 한계점을 명확히 이해하고, 이에 대한 극복방안을 모색하여 교육 게이미피케이션을 활성화하는 것이 본 논문의 목적이다. 본 논문에서는 인력교육 현장에서 게이미피케이션을 통해 교육에 게임을 접목할 경우에 발생하는 역효과와 한계점을 관찰연구를 통해 정리하고, 이에 대한 피교육자의 의견을 인터뷰 형식으로 추가하였다. Fun and happiness are the intrinsic values of the human beings. Game is one of the most efficient tools which satisfies those intrinsic values. Approaches and methods combining game and education to provide the enjoyable education environments have been increasing. As use of gamification in corporate and school education environments for human resources is increasing, significant voices of concern on the limitations and side effects of combining game and education are continuously increasing. The purpose of this paper is to energize the use of gamification in education environments by clarifying the limitations and side effects of gamification and seeking ways to overcome those factors. This paper summarizes an observational research on the limitations and side effects of gamification in education environments, and provides the interviewees' opinions on gamified classes.

In this paper, we designed and implemented a semantic social network system in Korea Institute of Oriental Medicine (abbreviated as KIOM). Our social network system provides the capabilities such as tracking search, ontology reasoning, ontology graph view, and personal information input, update and management. Tracking search provides the search results by the research information of relevant researchers using ontology, in addition to those by keywords. Ontology reasoning provides the reasoning for experts, mentors, and personal contacts. Users can easily browse the personal connections among researchers by traversing the ontology by graph viewer. These allows KIOM researchers to search other researchers who could aid the researches and to easily share their research information.

Although the judgment of constitutions is given according to the Sasang Typology in domestic korean medicine hospitals and universities, the unified constitution clinical information has not been accumulated. Therefore, in this paper, based on collection items where oriental doctors and experts have already agreed, we construct the input system which correctly and effectively collects the clinical information of persons of which constitutions are distinguished explicitly. In the future, the input system could be utilized to collect clinical information continuously and will help to search and analyze the constitution clinical information.

인터넷 차단 시스템은 기업내부에서 직원들의 인터넷 사용 내역에 대한 세부적 통제 수단으로 많이 각광받고 있다. 인터넷 차단 시스템은 기업의 인터넷 사용 형태에 많은 변화를 가져오지만 아직까지 이의 효과에 대한 세부적인 연구가 진행된 사례가 없다. 본 논문은 인터넷 차단 시스템의 도입에 대한 경제적 효과를 분석하여 인터넷 차단 시스템을 현재 운영중이거나 도입에 대하여 검토 중인 기업의 투자 및 운영에 대한 의사결정지표를 제시한다. 기존 연구를 통해 인터넷 차단 시스템에 대한 비용 및 효과 측정 수단을 개발하였으며, 실제 기업 전산망에 인터넷 차단 시스템 및 관련 측정 시스템을 구축하여 시스템 구축 전후의 추이 변화를 측정하여 효과 분석에 사용했다. 결론적으로 인터넷 차단 시스템이 일부 역효과에도 불구하고 기업의 생산성 향상 및 통신 대역폭의 개선에 매우 긍정적인 효과를 준다고 파악하였다. To justify the economic impacts of the internet access management is a purpose of this paper. Previous researches on economic justification were reviewed and the internet access management system, sniffer, and firewall were implemented to monitor real-time sessions and to record blocked attempts. This paper suggests the impact factors and measurement methods to justify the economic values of the internet access management system. Finally, this paper proves that the overall impacts of the internet access management system have a positive value because filtering mechanisms cause users to lose a small number of URLs including useful information and to diminish refreshment but save users from various risk points and enhance labor productivity.

The static inverter is mainly used to provide with the electric power of various loads in the train. In the recent european projects, the specification of static inverter become harder, and many additional service function is expected. It takes long time and high cost to develope a static inverter with these high performances and additional function. But, these are became general demands for static inverter in the many projects from now on. The APSE(Auxiliary Power Supply Equipment) is a static inverter of high performance to satisfy the severe specification and various service function following these tendency for Athens project. In this paper, the specification of APSE and various service functions are introduced to look about current tendencies of static inverter.

In this paper, we designed and implemented an integrated search and collaboration system. Users can search the traditional korean medicine knowledge in our system, which consists of medicinal materials, formulas, diseases, terminology, and clinical information. In general, the existing information systems providing the korean medicine knowledge do not provide the update function. Thus, it can be a problem if there are incomplete information. In order to solve this problem, our system implements the functions that users can work together to improve the knowledge. Therefore, wrong information can be updated easily so that flexible management about the korean medicine information is possible.
