Anti-islanding scheme of grid-connected inverter is a key function of standards compliance, since unintentional islanding results in safety hazards, reliability, and many other issues. Therefore, many anti-islanding schemes have been researched, however, most of them have problems, which deteriorate performance of islanding detection under parallel-operation. Therefore, this paper proves the reason of problems and proposes a new anti-islanding scheme that has precise islanding detection under parallel-operation in single-phase and three-phase system. Finally, both simulation and experimental result validate the proposed scheme.

환경 불확실성이 정보시스템수용에 미치는 영향에 관한 연구

김태균,장원경 명지대학교 금융지식연구소 2008 금융지식연구 Vol.6 No.1

대부분의 기업들은 경쟁적 환경 또는 환경 불확실성(동태성, 이질성)에 직면하고 있다. 이를 극복하기 위하여 기업들은 정보처리능력과 조직의 유연성을 높이기 위한 방법으로 정보시스템에 많은 투자를 하고 있다. 혁신적인 정보시스템은 불확실한 상황을 보다 효과적으로 운영할 수 있는 기능을 제공하고 있기 때문이다. 본 연구는 사용자 믿음(호환성, 지각된 용이성, 지각된 유용성)이 불확실한 환경에서 사용자 수용 의도에 어떠한 영향을 미치는가에 대한 내용으로 PLS-GRAPH 3.0을 분석에 이용하였다. 분석결과 호환성은 불확실한 환경이 높은 집단에서 지각된 유용성과 수용 의도에 더 큰 영향을 미치고 있었으나, 지각된 용이성과 지각된 유용성은 지각된 유용성과 수용의도에 낮은 집단의 사용자들이 더 많은 영향을 나타내는 것으로 밝혀졌다. Firms in every industry have encountered increased environmental uncertainty and competitive changes in their external environments. To manage environmental uncertainty (EU), firms are investing in Information Systems (IS) to increase their information processing capacity and their flexibility to adopt to EU. Innovative IS is that have to enable firms to meet the challenges of an uncertain environment more effectively. EU has two different dimensions: environmental dynamism and environmental heterogeneity. This study investigates the impact of users` beliefs(compatability, perceived ease of use; PEOU and perceived usefulness; PU) on user behavioral intention (BI) between low and high EU. Data analysis using PLS-GRAPH 3.0 indicated that compatability has a positive impact on BI in high EU compared with low EU. However, PEOU has no significant effect on the PU and PU has no significant effect on the BI in high EU compare with low EU. Our findings also demonstrated that PEOU and PU in an EU of lower, rather than higher EU are more likely to adopt IS. This paper concludes with discussions and implications for researchers and practitioners.

( Yong Suk Cha ),( Doe Kyune Yoo ),( Hee Yoon Nam ),( Kyung Ro Chang ) 한국체육학회 2015 국제스포츠과학 학술대회 Vol.2015 No.1

Purpose: Since 2015, the Korea Baseball Organization (KBO) combined their identity as ``KBO League`` to maximize the value of professional baseball while opening a new era consisting 10 professional baseball teams with a new team, kt wiz. The KBO league, which is truly positioned as a national sport, have rapidly developed with great mark in international competitions, marketing activities by each clubs, and professional channel for baseball league. Although it has been thirty-four years that the Korean Professional Baseball league was founded, ticket issues are still on the question. It`s especially harder to get ticket for rival matches, post seasons, and Korean series. Therefore, doubt and distrust of fans have never disappeared, and these problems could be a decisive variable for popularity of professional baseball league affecting fan`s attitude toward the KBO league. Method: The purpose of this study was to investigate fan`s recognition about unfair ticket sales in professional baseball and what effect it has on fan`s attitude towards the KBO. More specifically, the analysis focused on the differences in changes of league trust, league image, and league reputation depending on crisis responsibility about ticket sales. In order to fulfill this purpose, a questionnaire survey was conducted on 350 baseball fans and 323 samples were used for the analysis. Frequency analysis, reliability analysis, correlation analysis and two-way RG-RM ANOVA were carried out using PASW 18.0 program. Result: In terms of league trust, the interaction effect between crisis responsibility on unfair ticket sales and pre-post measurements appeared to be significant. A degree of decline in league trust was significantly higher in a group which perceived the crisis responsibility of the KBO at higher level compared to those who perceived the crisis responsibility at lower level. Furthermore, for league image, the interaction effect between crisis responsibility on unfair ticket sales and pre-post measurements appeared to be significant. A degree of decline in league image was significantly higher in a group which perceived the crisis responsibility of the KBO at higher level compared to those who perceived the crisis responsibility at lower level. However, no significant interaction effect was evident between crisis responsibility and pre-post measurements for league reputation. Conclusion: This study proved that league trust and image of the KBO have been changed after fans perceived unfair ticket sales. Thus, there should be a constant effort into improving systems for fair and clear ticket sales.

디지털증거 압수수색에 관한 연구

박봉진 ( Bong Jin Park ),김상균 ( Sang Kyune Kim ) 제주대학교 법과정책연구소 2013 法과 政策 Vol.19 No.1

사이버공간에서 발생하는 각종 사이버범죄에 대한 정책적 대응은 사이버범죄의 성격과 디지털증거에 따라 체계적이고 구체적으로 이루어져야한다. 사이버범죄의 새로운 인터넷사기 수법으로 보이스 피싱의 경우 피해자가 계속증가하고 있고 매스컴에 자주 보도되고 있는 상황이며, 사이버음란물, 사이버성매매, 소프트웨어불법복제, 사이버도박 등이 지속적으로 문제되고 있다. 사이버세계에서의 비대면성·익명성은 죄의식을 감소시키고, 수많은 불법적이고 유해한 정보를 수집, 변형, 유통함으로써 공공의 안녕과 사회질서를 혼란스럽게 하는 결과를 야기하고 있다. 본 연구에서는 사이버범죄의 개념과 유형, 그리고 최근 5개년간 우리나라의 사이버범죄 현황의 추이를 살펴보고자 한다. 사이버범죄는 정보적, 국가적, 세계화적, 네트워크적 특성, 특히 현재성으로 인해 수사 및 형사사법절차에 있어, 개인의 안전과 프라이버시의 보호 등 많은 법적 어려움이 발생하고, 정보화 사회가 되어가면서 컴퓨터에 저장된 정보는 형사소송에서 증거로서 더욱 중요한 역할을 하고 있다. 2011.7.18 공포되어 2012.1.1 부터 시행되는 형사소송법은 디지털증거에 대한 압수수색제도를 명문의 규정으로 제시하였다. 그러나 디지털증거의 압수수색에 대한 부분적인 형사소송법의 규정이 그 증거조사방법과 증거능력과 관련하여 충분한 근거조항이 되지 못하고 있으므로 이에 대한 문제점과 개선방향(보완입법)을 제시해 본다. Cybercrime is one of the terms used to denote the use of computer technology to engage in unlawful activity. Computer crime, high-tech crime and information-age crime. Most of the cybercrime we have seen so far is nothing more than the migration of real-world crimes into cyberspace The other significant portion of cybercrime consists of specially defined cyber-offences-hacking, cracking and virus dissenmination-that are online version of real-world crimes. And Cybercrime are different to more conventinal crimes because of their mediation by computer technology. The mark of a true cybercrime is that it disappear once networked technology is removed characteristice of Informational. We are living in the digital age. Lots of people in the world are using the Internet and so we are spending our lifetime in the Cyberspace through the Internet. Digital evidence is difficult to treat, because digital information is easy to forge, alter, delete and modify. So several digital evidence collection tools and forensic tools are developed. However there are many problem of composition which is whole due process from evidence collection to submitting to the court because existing digital evidence collection process and tools have a vulnerability of guaranteeing integrity. Digital evidence of electronic evidence is probative information stored of transmitted in digital form. A party to a court case may use it at trial. Before accepting digital evidence, a court will determine if the evidence is relevant, whether it is authentic, if it is hearsay-evidence, and whether a copy is acceptable or the original is required. Digital evidence tends to be easily eliminated modified and duplicated. Digital evidence is often attacked for its authenticity due to the ease with which it can be eliminated of modified. Digital evidence is often ruled inadmissble by court because it was obtained without authorization. The intangible information cannot be viewed in the eyes nor defined in any forms. Evidence may not remain at place where a criminal activity has occurred. It is therefore necessary to have the special knowledge and skills for efficient investigation. In 2011, however, Korea Criminal Procedure was amended to include the duty to produce digital evidence. Nonetheless, the law enforcement demand to amend additionally the law to expand the scope of the duty to assist digital search warrant execution resulting in including duty to preserve digital evidence and duty to assist warrant execution. Some scholars and Judges have expressed different opinion over the additional revision.

Chung, Hae-Young,Song, Mi-Kyune,Park, Mi-Hyun The Korean Society of Community Nutrition 2003 Journal of community nutrition Vol.5 No.1

A study was conducted to investigate the anthropometric indices, fat distribution, eating habits and levels of daily physical activity based on the body mass index (BMI ; kg/㎡) of 180 female college students. This stady was based on survey 2001 using a questionnaire. The results are as follow ; The mean age, height, weight and BMI were 20.41 ${\pm}$ 1.82 years, 161.86 ${\pm}$ 4.51cm, 53.49 ${\pm}$ 7.02kg, and 20.43 ${\pm}$ 2.65kg/㎡, respectively. The group with BMI of under 20 (the lean group) comprised 48.9% : the group with BMI of 20 to 25 (the normal group) comprised 44.4% and the group with BMI of over 25 (the obese group) comprised 6.7% of the subjects. Even though the lean and the normal groups were determined according to BMI. 12.5% of the lean group and 31.3% of the normal group had more than 25% body fat. Of the students, 11.5% of the lean group, 25.0% of the normal group and 58.3% of the obese group had of more than 0.8 waist/Hip Ratio (WHR). The medical problems suffered by the subjects were constipation (24.4%), gastroenteritis (20.6%), anemia(15.0%) and edema(13.3%), which was a result of their eating habits. Out of all the subjects, 27.2% ingested their meals irregularly, 74.4% skipped breakfast, and 92.4% of the lean group, 89.2% of the normal group and 81.8% of the obese group ingested snacks on a daily basis. Their favorite types of snacks were cookies breads and cakes (33.7%), spicy sliced rice cakes pork sausage and boiled fish cakes (18.5%), fruits (15.2%), juices and sodas (13.5%) and hamburgers and pizzas (3.9%). Their consumption of high calorie and processed foods was high, Of the subjects, 38.9% ate out daily. 45.1% had tried weight loss. Those with large upper bodies comprised 11.5%, large intermediate bodies 18.5% and large lower bodies 69.0%. Most of the students were dissatisfied with their body snaps. Of the subjects, 95.1% exercised irregularly. Daily physical activity tended to increase significantly with an increase in BMI : the lean group's average energy consumption was 1509.40㎉ the normal group's was 1792.21㎉ and the obese group's was 2334.63㎉, which were below the recommended value. This study suggests that the maintenance of an ideal weight, the improvement of eating habits and adequate exercise are needed for female college students to improve their health and nutritional status.
