    Thesis(Master) -- KDI School: Master of Public Management, 2022This research paper aims to check whether there are differences in government attention and social attention on major water management issues and to explore how to derive the differences, using text mining techniques based on government press release and online news data. For this research, keywords on water management issues were derived from press release of the Ministry of Environment (MOE) and online news articles from 2016 to 2020, and the frequency and content of the keywords were compared in terms of governmental and social side. In this process, the Bigram and Word2Vec methods were used to derive keywords that could be sufficiently expressed information of issues on water management. As a result of this research, it was confirmed that the extent of the governments attention and social attention may depending on the water management issues during same period, and that what issues differed by year. Finally, I think this research result is meaningful in laying the foundation for more research and development in a more advanced direction, not a methodology that dramatically improves the analysis of policy issues.1.

    In Korea, concerns over child sexual abuse have been rising recently because of the fatal consequences for victims and the fact that the incidence has continued to increase even after the government’s efforts to intensify the punishment of perpetrators. While the angry and painful responses of many Koreans to recent incidents of child sexual abuse, such as the Jo Doo Soon case, are intense enough to lead to the government’s urgent reactions to resolve it, few systematic, comprehensive approaches to coping with and preventing sexual abuse of children and adolescents have been developed. To establish efficient systems for coping with and preventing child sexual abuse, well trained experts such as physicians, psychologists, and social workers, and social service systems to train these professionals as well as institutions to provide appropriate medical and welfare services are essential. However, the current systems supporting victims of child sexual abuse, such as the Sunflower Children’s Center, One-stop Center, and other counseling centers, are not well coordinated and lack knowledgeable professionals. Furthermore, since there is no responsible government department to integrate the social welfare and legal systems for child sexual abuse, services are inefficient and decentralized. Thus to cope with and prevent child sexual abuse in Korea, we need to establish good, efficient social service systems to train experts, to coordinate each organizations, to integrate child sexual abuse treatment and prevention into the general child welfare system, and to establish enough service centers to provide all legal, medical, welfare, and other services requiredope

    Civilization using electromagnetic wave has a lot of advantages which is completely changing the life pattern of the mankind. However, Malfunction by various interference between electric equipments and hazards on health have become serious problems. Thus, Regulation of electromagnetic waves have been increasingly tighten up in most of the world, including Republic of Korea. Most of the major countries have administered certified international laboratory under the ILAC in order to solve problems such as trade barriers from electric equipment which is not satisfied regulation of electromagnetic waves. In Korea, KOLAS has made mutual recognition arrangements with the ILAC and laboratories accredited KOLAS have improved the reliability and repeatability of measurement through an accurate analysis of international standards. In this dissertation, problems about EFT/Burst test, referenced in the IEC-61000-4-4 of the international standard related to verifying EMC of electric equipments, was analyzed and measuring reliability was studied. As a result, the improved EFT/Burst immunity test method which considering the radiated EFT/Burst signals has been proposed. Firstly, the test sample was set up by the standard regulation and then the +4 kV EFT/Burst signal was generated by 1 m long power cable for 1 minute. Consequently, it was found that not only induced EFT/Burst signal along power line of EUT, but also directly radiated emission signal from the EFT/Burst signal generator. The radiated emission signals was 30dB higher than limit of CISPR 22 which is international EMC standard. Moreover, the electric field strengths were measured by changing the distance from the point with the maximum radiated emission to the electric field strength tester. As a result, this electric field strength was 23 V/m which is higher than international EMC standard test level (CISPR 24). Therefore, it was confirmed that the probability of malfunction may be high when radiated emission of EFT/Burst noise exists near the EUT. Then, reliability of measurement results of IEC61000-4-4 standard was discussed through the field strength measurement according to the separated distances of the receiver to the maximum source of the radiated EFT/Burst signals, the analysis of the influence from the power line type and length, the analysis depends on the type of the test sample, and the studies of suppression effect from the radiated EFT/Burst signals. Consequently, the radiated EFT/Burst signals directly cause malfunction of EUT, and it was confirmed that malfunctions of EUT can be solved by applying countermeasure method of radiated noise. In addition, it was proposed that countermeasure method from EFT/Burst signals should be considered not only for conductive noise but also for the radiated noise. Furthermore, reliable arrangement of EFT/Burst immunity test were searched according to the structure of the EUT’s enclosure, materials, and operating environment. In this dissertation, the improved EFT/Burst immunity test method which considering the radiated EFT/Burst signals has been proposed.Nomenclature Abbreviations Abstract 제1μž₯ μ„œ λ‘  1 1.1 연ꡬ λ°°κ²½ 및 λͺ©μ  1 1.2 연ꡬ 방법 3 제2μž₯ μ „μžνŒŒ λ‚΄μ„± μ‹ ν˜Έμ— κ΄€ν•œ 이둠 및 μ‹œν—˜ 5 2.1 μ „μžνŒŒμ ν•©μ„± 5 2.1.1 EMC κ°œμš” 6 2.1.2 EMCλ₯Ό κ³ λ €ν•œ 섀계법 8 2.1.3 EMC 규제 규격 9 2.2 λŒ€ν‘œμ μΈ EMC μ‹œν—˜μ˜ μ’…λ₯˜ 및 μ‹œν—˜ 방법 16 2.2.1 볡사성 λ°©μ‚¬μ‹œν—˜ 17 2.2.2 전도성 λ°©μ‚¬μ‹œν—˜ 19 2.2.3 작음 μ „λ ₯μ‹œν—˜ 22 2.2.4 방사 λ‚΄μ„±μ‹œν—˜ 25 2.2.5 전도 λ‚΄μ„±μ‹œν—˜ 28 2.2.6 μ •μ „κΈ° λ°©μ „ λ‚΄μ„±μ‹œν—˜ 30 2.2.7 μ „κΈ°μ μœΌλ‘œ λΉ λ₯Έ κ³Όλ„ν˜„μƒ/λ²„μŠ€νŠΈ λ‚΄μ„±μ‹œν—˜ 32 2.2.8 μ„œμ§€ λ‚΄μ„±μ‹œν—˜ 32 2.2.9 μ „μ••κ°•ν•˜, μˆœμ‹œμ •μ „ 및 전압변동 λ‚΄μ„±μ‹œν—˜ 35 제3μž₯ EFT/Burst λ‚΄μ„± μ‹œν—˜ 및 방사성 작음의 λ°œμƒ 38 3.1 μ „κΈ°μ μœΌλ‘œ λΉ λ₯Έ κ³Όλ„ν˜„μƒ/λ²„μŠ€νŠΈ λ‚΄μ„± μ‹œν—˜ 38 3.1.1 μ‹œν—˜ λͺ©μ  38 3.1.2 μ „κΈ°μ μœΌλ‘œ λΉ λ₯Έ κ³Όλ„ν˜„μƒ/λ²„μŠ€νŠΈ μ‹ ν˜Έ 38 3.1.3 μ‹œν—˜ ν™˜κ²½ 및 μ…‹μ—… 41 3.1.4 μ‹œν—˜ 인가 레벨 43 3.1.5 μ‹œν—˜ 절차 및 평가 44 3.2 EFT/Burst 볡사 작음의 λ°œμƒμ›μΈ 뢄석 45 3.2.1 전도성 μ‹ ν˜Έμ˜ μ „λ‹¬κ²½λ‘œ 45 3.2.2 전도성 μ‹ ν˜Έμ˜ λ°©μ‚¬νŠΉμ„± 48 3.2.3 μ‹ ν˜Έ 방사와 κ΄€λ ¨λœ μ•ˆν…Œλ‚˜ 이둠 50 3.2.4 μ „κΈ°μ μœΌλ‘œ λΉ λ₯Έ κ³Όλ„ν˜„μƒ/λ²„μŠ€νŠΈ μ‹ ν˜Έμ˜ λ°©μ‚¬νŠΉμ„± 55 제4μž₯ EFT/Burst 볡사 작음의 μΈ‘μ • 및 μ‹œν—˜ν’ˆμ˜ 영ν–₯도 뢄석 59 4.1 EFT/Burst 볡사 작음의 λ°œμƒμ› 탐ꡬ 및 검증 59 4.1.1 κ·Όμ ‘ν”„λ‘œλΈŒλ₯Ό μ΄μš©ν•œ EFT/Burst 볡사 작음의 λ°œμƒμ› 탐ꡬ 59 4.1.2 ν•„λ“œν”„λ‘œλΈŒλ₯Ό μ΄μš©ν•œ EFT/Burst 볡사 작음의 λ°œμƒμ› 검증 63 4.2 EFT/Burst 볡사 작음의 μΈ‘μ • 65 4.2.1 κ³΅μΈμ‹œν—˜λ²•μ— μ˜ν•œ EFT/Burst 볡사 작음의 μΈ‘μ • 65 4.2.2 방사 λ‚΄μ„± μ‹œν—˜μ˜ ꡭ제 κ·œκ²©μΉ˜μ™€ EFT/Burst 볡사 작음의 비ꡐ 69 4.3 λ‹€μ–‘ν•œ μ‹œν—˜ μ‘°κ±΄μ—μ„œμ˜ EFT/Burst 볡사 작음의 영ν–₯도 뢄석 71 4.3.1 이격 거리에 λ”°λ₯Έ 전계강도 μΈ‘μ • 71 4.3.2 μ‹œν—˜ν’ˆ μ „μ›μ„ μ˜ μ’…λ₯˜ 및 길이에 λ”°λ₯Έ 영ν–₯ 77 4.3.3 μ‹œν—˜ν’ˆ μ’…λ₯˜μ— λ”°λ₯Έ 전계강도 μΈ‘μ • 79 4.3.4 EFT/Burst 볡사 작음의 μ–΅μ œ 효과 82 제5μž₯ EFT/Burst λ‚΄μ„±μ‹ ν˜Έμ˜ λŒ€μ±… λ°©μ•ˆ 및 μ‹œν—˜ λ°©λ²•μ˜ μ œμ•ˆ 86 5.1 볡사 μž‘μŒμ„ κ³ λ €ν•œ μ‹œν—˜ν’ˆμ˜ EFT/Burst λ‚΄μ„± λŒ€μ±… λ°©μ•ˆ 86 5.1.1 일반적인 EFT/Burst λ‚΄μ„±μ‹ ν˜Έ λŒ€ν•œ λŒ€μ±… λ°©μ•ˆ 86 5.1.2 EFT/Burst 볡사 μž‘μŒμ— μ˜ν•œ μ‹œν—˜ν’ˆμ˜ μ˜€λ™μž‘ 및 λŒ€μ±… 90 5.2 EFT/Burst 볡사 작음 μ–΅μ œλ₯Ό μœ„ν•œ μ‹œν—˜ μ‹œμŠ€ν…œμ˜ μ œμ•ˆ 97 5.2.1 EFT/Burst λ‚΄μ„±μ‹œν—˜ μ‹œμŠ€ν…œ ꡬ성을 μœ„ν•œ ν™˜κ²½ κ³ μ°° 97 5.2.2 μ‹œν—˜ λŒ€μƒ 및 운용 ν™˜κ²½μ— λ”°λ₯Έ λ‚΄μ„±μ‹œν—˜ μ‹œμŠ€ν…œμ˜ μ œμ•ˆ 199 제6μž₯ κ²°λ‘  101 μ°Έκ³ λ¬Έν—Œ 103 λ³Έ 연ꡬ와 κ΄€λ ¨λœ λ…Όλ¬Έ 싀적 10
