본 연구는 한국직업능력개발원(KRIVET)에서 수행한 「진로교육 현황조사」 중 2016년도 자료를 활용하여 초등학생 학부모들의 학교만족도에 대한 진로관련 활동의 영향을 분석하고자 하였다. 이를 위해 본 연구에서는 2016년 「진로교육 현황조사」 학부모 설문에 응답한 초등학생 학부모 5,467명을 대상으로, 변수들 간의 관계에 대한 구조방정식 모형을 설정한 후 영향 관계를 분석하였다. 분석결과 초등학생 학부모들의 ‘학교만족도’에 대하여 ‘진로상담 만족도’, ‘진로활동 만족도’, ‘부모- 자녀 진로대화’, ‘진로자료 활용 만족도’가 통계적으로 유의미한 영향력을 행사하고 있음을 확인할 수 있었다. 이러한 연구결과는 학교 진로교육 관련 활동이 학부모의 ‘학교만족도’에 상당한 영향력을 행사하고 있음을 의미한다. 특히, 본 연구에서는 ‘진로상담 만족도’와 관련하여 학교에서의 진로상담이 다양한 진로관련 활동에 영향력을 행사하고 있음을 실증적으로 확인할 수 있었다. 이 외에도 ‘진로활동의 만족도’와 ‘진로자료 활용 만족도’는 모두 초등학생 학부모들의 ‘학교만족도’에 정적인 영향을 주고 있었으며, 이는 질적으로 우수한 진로활동 프로그램의 운영과 개발의 중요성을 시사해주며, 지속적으로 해당 요소들의 체계적인 관리가 요청됨을 의미한다. 그뿐만 아니라, ‘부모-자녀 간의 진로관련 대화’도 학부모의 ‘학교만족도’에 영향을 주는 주요한 변수임을 확인할 수 있었다. 이에 반해, 학부모의‘학교만족도’에 대하여 ‘진로정보 필요도’의 경로는 통계적으로 무의미함을 확인하였다. 위와 같은 연구결과를 바탕으로, 초등학교 학부모의 ‘학교만족도’를 제고하기 위해 학교에서 양질의 진로활동을 제공할 필요성, 초등교사의 진로상담 역량을 제고하여 진로상담을 활성화 할 필요성, 학생·학부모의 요구에 부합하는 진로교육자료를 체계적 제작하여 보급하는 것의 중요성 등 정책적인 시사점을 제시하였다. This study analyzes the effect of career-related activities on elementary school parents’ school satisfaction by using 2016 data from the 「Career Education Status Survey」 conducted by the Korea Research Institute for Vocational Education & Training(KRIVET) since 2016. To this end, in this study, using the response data of 5,467 parents of elementary school students who responded to the 2016 「Career Education Status Survey」 parent questionnaire, the influence relationship is analyzed after establishing a structural equation model. The results are reported as follows. First of all, career counseling satisfaction, career activity satisfaction, parent-child career dialogue, and satisfaction with using career data exert a statistically significant influence on the school satisfaction of elementary school parents. In particular, in this study, it is empirically confirmed that career counseling at schools influences various career-related activities in relation to the career counseling satisfaction. These findings mean that activities related to school career education exert considerable influence on parents' school satisfaction. These also suggest the importance of the operation and development of quality career-related programs. Second, the influence of the need for career information on school satisfaction is confirmed to be statistically meaningless. Based on these results, policy implications such as the need to provide quality career activities in schools to enhance the school satisfaction of elementary school parents, the need to promote career counseling by enhancing career counseling capabilities, and the importance of career education materials that meet the needs of students and parents.

Web browser secureness with respect to CVSS

( Hyunchul Joh ) 한국정보처리학회 2014 한국정보처리학회 학술대회논문집 Vol.21 No.2

Analysis of characteristics in software vulnerabilities can be used to assess security risks and to determine the resources needed to develop patches quickly to handle vulnerability discovered. Being a new research area, the quantitative aspects of software vulnerabilities and risk assessments have not been fully investigated. However, further detailed studies are required related to the security risk assessment, using rigorous analysis of actual data which can assist decision makers to maximize the returns on their security related efforts. In this paper, quantitative software vulnerability analysis has been presented for major Web browsers (Internet Explorer (IE), Firefox (FX), Chrome (CR) and Safari (SF)) with respect to the Common Vulnerability Scoring System (CVSS). The results show that, almost all the time, vulnerabilities are compromised from remote networks with no authentication required systems, and exploitation aftermath is getting worse.

Dual-Band Branch-Line Coupler With Port Extensions

Hyunchul Kim,Byungje Lee,Myun-Joo Park IEEE 2010 IEEE transactions on microwave theory and techniqu Vol.58 No.3

<P>A new branch-line coupler structure with port extensions is proposed for the dual-band operation. The conventional branch-line coupler structure is adapted to the dual-band operation by inserting a transmission line section at the input ports and modifying the branch parameters. The dual-band performance of the proposed coupler is verified theoretically through the rigorous microwave circuit analysis and the exact design equations are derived in concise form. The design, simulation, and measurement results validate the dual-band capability of the proposed coupler with the same quadrature phase relation between the two band frequencies.</P>

Spillover Effects of Temporary Price Cuts

Hyunchul Kim,Kyoo il Kim 한국계량경제학회 2016 JOURNAL OF ECONOMIC THEORY AND ECONOMETRICS Vol.27 No.1

Temporary price cut is one of the most popular marketing tactics in the supermarket industry. We examine the effects of price promotions on storewide profitability. Using a treatment effect setting we estimate the shortterm and long-term promotional effects that spill over into other product categories using supermarket scanner data. In an effort to remove the selection bias due to differences in the subpopulations of the treatment and the control groups, we use several nonparametric imputation methods. The detailed information on household level purchases and store visits allows us to improve matching quality in the estimation. We find that the effects of price promotion on storewide sales deteriorate over time and that the spillover effects are substantial. This suggests that pricing strategies of multi-product retailers maximizing storewide profits should take into account the spillover effects of short-term pricing.

Hyunchul Choi,Semi Jeong,Cheong Lee,Gwangjun Go,Kiduk Kwon,Seong Young Ko,Jong-Oh Park,Sukho Park 제어로봇시스템학회 2013 제어로봇시스템학회 국제학술대회 논문집 Vol.2013 No.10

For the actuation of mini-robots, various types of electromagnetic based actuation (EMA) methods were proposed. Compared with conventional actuation system using electric motor, EMA system has many advantages for the wireless actuation of mini-robots. This paper introduces our proposed biomimetic swimming mini-robots such as tadpole robot and jellyfish robot. The developed biomimetic swimming mini-robots could be driven by an external alternating magnet field using three pairs of Helmholtz coils. The swimming mini-robots consist of a buoyant swimming mini-robot body, permanent magnets, and fins. Especially, the tadpole swimming mini-robot has a single fin which is directly linked to the permanent magnet and the jellyfish swimming mini-robot has multiple fins which have a permanent magnet at the end of fins. The external alternating magnetic field from three pairs of Helmholtz coils could generate the propulsion and steering force of the tadpole mini-robot and the jellyfish mini-robot in 2- and 3-dimensional (D) space.

The external alternating magnetic field from three pairs of Helmholtz coils could generate the propulsion and steering force of the tadpole mini-robot and the jellyfish mini-robot in 2- and 3-dimensional (-D) space. Firstly, we demonstrated the fabrications of the EMA coil system and the mini-robots. Secondly, we summarized the locomotive algorithms of the mini-robots using EMA. Thirdly, we setup the control system for the EMA driven mini-robots, which consists of EMA coils, dual cameras, controller, power amplifier, and conventional joystick. Through various experiments, we evaluated the locomotion algorithms the swimming mini-robots using EMA system. Finally, we demonstrated the performances of the swimming mini-robots in 2-D and 3-D space.

BioProber: Software System for Biomedical Relation Discovery from PubMed

Hyunchul Jang,Jaesoo Lim,Joon-Ho Lim,Soo-Jun Park,Kyu-Chul Lee IEEE 2006 Conference proceedings Vol.2006 No.8

<P>The numbers of articles and journals that are published are increasing at a considerable rate, and the published information is growing continuously and fast. Because of this, researches to acquire knowledge automatically have been carried out in the areas of information retrieval, information extraction and text mining. Information retrieval approaches are good for specific topics that the number of related articles is small. But, if the number is bigger, searching skill and knowledge acquisition ability are useless. Though many efforts have been made to extract information from literature, many approaches have concentrated on specific entities, such as proteins, genes and their interactions, and much information is still remained in unstructured text. So, we have developed a system that discovers relations between various categories of biomedical entities. Our system collects abstracts from PubMed by queries representing a topic and visualizes relationship from the collection by automatic information extraction</P>
