A novel programming architecture for antifuse FPGA(Field Programmable Gate Array) is described. This architecture prevents programming transistors from breakdown which occurs due to high voltage across the transistors during antifuse programming. Extra mask and processes can be avoided using this proposed architecture. To reduce the applied voltage across the terminals of programming transistors, different voltage ranges are supplied to vertical and horizontal tracks; between programming voltage Vp and Vp/2 for vertical tracks and between Vp/2 and 0V for horizontal tracks. Therefore, Maximum voltage across the programming transistors is half of the programming voltage and an designated antifuse can be programmed by applying maximum voltage for vertical track and minimum voltage for horizontal track while others are subjected to voltage difference below Vp/2.

Purpose : The purpose of this study is to directly understand the health condition of residents of mental health sanatoriums nationwide, which has been difficult to ascertain in surveys conducted to date. The study presents specific measures for improving the health of these residents. Methods : A "physical examination questionnaire for residents of mental health sanatoriums" was developed to check the basic physical condition of residents, and 20 out of 59 mental health sanatoriums nationwide were randomly selected. Medical personnel visited the sanatoriums, interviewing and examining the residents in person. A total of 396 health surveys were completed. Results : Many of the residents were underweight but had abdominal obesity. It was confirmed that chronic diseases among the residents were not diagnosed early or were not properly managed. Among the subjective symptoms complained of by the residents, musculoskeletal symptoms were the most common. Oral examinations revealed a serious level of oral health problems among the residents, including dental caries and missing teeth. Basic physical examinations found health problems that required additional examination or medical treatment. Blood pressure abnormalities made up the highest percentage of the health problems. Conclusion : Regular health surveys are needed to determine the health condition of residents of mental health sanatoriums. Access to and quality of primary medical services within the sanatoriums need to be dramatically improved. A delivery system for severe diseases and emergency medical care in the sanatoriums should also be specifically presented. The residents should be notified upon admission and during their stay that they have the right to the enjoyment of the highest attainable standard of mental and physical health. The issue of health rights should be addressed within a larger framework of reorganizing management plans for people in the community ― not only residents ― with chronic mental illness.

The purpose of this study is to provide implications for improving the safety behavior of university lab students by grasping the relationship between leaders' safety leadership, the lab's safety climate, and individual safety motivation variables. To this end, a survey was conducted on nationwide university laboratories, and the main results are as follows. First, transformational and transactional safety leadership had a positive effect on safety behavior, while the laissez-faire one had a negative impact.Second, it was found that the laboratory safety climate plays a mediating role in the relationship in which safety leadership affects safety behavior. Third, it was found that individual safety motivation was governed by the laboratory safety climate's effect on safety behavior. Fourth, individual safety motivation was found to control the mediating effect of the laboratory safety climate in the relationship between safety leadership and safety behavior. The conclusion of this study is the following: to strengthen the safety behavior of university laboratory students, the laboratory manager must operate the laboratory with a transformational and transactional safety leadership. Additionally, educational institutions must effectively operate their own safety-day programs to create a safe climate for each laboratory and improve students' safety motives.
4차 산업혁명 기반 핵심기술에 대한 기술성숙도와 산업과 연계 타당성 연구

The core technology development of the Fourth Industrial Revolution is linked to the development of other core technologies, which will change the industrial structure in the future and create a new smart business model. In this paper, tried to analyze the technology maturity level and analyze the technology maturity. To do this, used technology trend information to investigate and integrate the market, policy, etc. Of core technology of the 4th Industrial Revolution to achieve a comprehensive maturity level. Because technology maturity measures are scored by technology developers, prejudices may be acted upon according to a person's tendency, which may be a subjective evaluation. It is also a measure of the maturity of individual technologies, and thus is not suitable for evaluating the overall system integration perspective. However, it is possible to evaluate the maturity before integrating the core element technologies constituting the whole system and to use it as a means to compare the effect of the whole system and its feasibility and play an important role in the planning of technology development. 4차 산업혁명의 핵심기술 발전은 다른 핵심기술의 발전과 연계되며, 이를 통하여 미래에 산업구조를 변화시키고 새로운 스마트 비즈니스 모델을 창출할 것으로 예측된다. 이에 본 논문에서는 기술 성숙도 분석을 통하여 기술 성숙도 수준을 진단할 수 있는 방안과, 기술 개발에 도움이 될 수 있는 연구를 수행하고자 하였다. 이를 위하여 기술 동향 정보를 이용하여 4차 산업혁명 핵심기술의 시장, 정책 등을 조사하고 종합하여 종합적인 성숙도 수준을 수행하였다. 기술 성숙도 측정값은 기술 개발자에 의해 배점되므로, 사람의 성향에 따라 편견이 작용되어 주관적인 평가가 될 수 도 있다. 또한 개별 기술의 성숙도에 대한 측정이므로, 전체 시스템 통합 관점의 평가에는 적합하지 않다. 하지만 전체 시스템을 구성하는 핵심 요소 기술들을 시스템에 연계하기에 앞서 성숙도를 평가하여 전체 시스템의 효과와 구현 가능성을 비교할 수 있는 수단으로 활용할 수 있으며, 기술 개발의 계획에 중요한 역할을 수행할 수 있을 것으로 기대된다.

The purpose of this study is to norm the engineering design competency test. To achieve the purpose of the study, a survey was conductedon engineering college students nationwide using engineering design competency test developed in the precedent study, and a totalof 2,859 questionnaires were analyzed. The main results are as follows. First, the national average of engineering design competencyscores was 158 out of 240 points. Second, there was no significant difference between genders in engineering design competency bybackground variables. On the other hand, there was a significant difference by major. It was found that mechanical and constructionmajors have higher engineering design competency than IT and chemical/material engineering majors. Also, the scores of engineeringdesign competency increased as the grade went up. Third, the number of courses related to engineering design did not affect by engineeringdesign competency, but the actual number of times of experience in engineering design was affected by engineering design competency.
