        한·중·일 3국의 외국인 유학생 유치 정책 비교 연구

        김한나(金한나), 우한솔(禹한솔), 이승호(李丞鎬) 서울대학교 교육연구소 2016 아시아교육연구 Vol.17 No.4

        본 연구는 한국, 중국, 일본 3국의 외국인 유학생 유치 현황을 살펴보고 정책의 특징을 종합적으로 비교함으로써, 우리나라 유학생 정책에 관한 시사점을 도출하고 학술적 이해의 지평을 넓히고자 하였다. 최근 들어 세계대학 간 교류가 급격히 확대되고 있으며, 외국인 유학생은 글로벌 교육협력의 핵심으로 주목받음에 따라, 한·중·일 3국 또한 적극적인 유학생 유치 정책을 추진해오고 있다. 이에 따라, 본 연구는 3국의 외국인 유학생 유치 정책이 전개된 과정과 유치 현황, 정책의 추진 배경 및 목적, 방안 등을 비교하였다. 분석 결과, 한·중·일 3국은 공통적으로 외국인 유학생 규모의 양적 성장을 이루어 냈지만, 유학생 출신국가 쏠림, 인문계열 편중 등의 문제가 있었고, 언어 문제로 파생된 취업 연계 문제가 정책적 과제로 제기되고 있었다. 한국의 경우 석·박사 고급인력과 응용과학 분야에서의 유학생 유치를 성과로 볼 수 있지만, 유학생 양적 확대에 따른 질 관리 문제는 여전히 지적되고 있다. 따라서 유학생 교육의 질적 향상을 바탕으로 유학생 유치 경쟁력을 강화할 수 있도록 정책의 우선순위를 조정하고, 중국과 일본의 사례를 참고함과 동시에 우리의 강점을 바탕으로 유학생 유치 정책의 차별화가 요구된다. 또한, 유학생 정책의 효과에 관한 실증적인 연구, 질 관리를 위한 평가 지표의 보완, 그리고 대학 차원의 노력이 함께 병행될 필요가 있다.

        의료광고에 대한 규제현황 및 개선방향

        김한나,김계현 아주대학교 법학연구소 2017 아주법학 Vol.10 No.4

        최근 의료기관 간 경쟁이 심화되면서 의료광고 역시 급증하고 있다. 특히 2007년 의료법 개정으로 의료광고에 대한 규제방식이 원칙적 허용, 예외적 금지로 금지사유를 규정하는 네거티브 방식으로 변경되어 의료광고가 크게 증가하였다. 한편, 최근 의료광고와 관련하여 헌법재판소는 의료법상 의료광고 사전심의 관련 규정을 위헌으로 판단한바 있다. 의료단체가 수행하고 있는 의료광고 사전심의가 행정권으로부터 자율성이 보장되지 않아 헌법상 금지하는 사전검열에 해당한다고 판단한 것이다. 의료광고 사전심의에 대한 헌법재판소의 결정으로 의료광고 관련 제도에 대한 수정이 필요하게 되었다. 의료광고 관련 제도 개편을 위한 핵심은 의료광고에 대한 심의 관련 업무가 행정권으로부터 독립되어 있는 민간심의기구를 통하여 자율적으로 수행될 수 있도록 하는데 있다고 볼 수 있다. 이에 관련 법령 개정이 요구되며, 심의제도 운용상 문제가 되는 부분들은 지속적으로 개선해 나가야 할 것으로 본다. 또한 민간 심의기구를 통한 심의의 활성화를 위한 유인책(인증제도 등)을 마련하는 등 의료광고 규제의 합리적 개선이 이루어져야 의료광고 규제의 실효성을 확보하여 허위‧과대광고를 방지하고 정확한 정보전달이 가능해질 것이다. 기존의 의료광고 규제제도가 소비자의 건강권 보호 및 불공정경쟁 방지의 관점에 입각하여 설계‧운영되어 왔다면, 향후 의료광고 규제제도는 의료인의 표현의 자유 내지 직업수행의 자유, 소비자 보호 내지 공정거래질서 확보를 균형 있게 조화시키는 방향으로 개선되어야 할 것이라 본다. As the competition among medical organizations intensifies, medical advertisements are rapidly increasing. Since the amendment of the medical law in 2007, the regulation method has been shifted to a negative format which stipulates grounds for limitation with principle permission and exceptional prohibition. Internet advertising, along with newspapers and magazines, is an important means of ads these days. Also, indirect advertising such as native ads is also increasing. Meanwhile, the Constitutional Court has ruled the regulations regarding pre-censorship of medical advertising under the medical law unconstitutional. The pre-censorship on medical ads conducted by medical organizations is not guaranteed autonomy from the administrative power, which pertains to an act of pre-censorship prohibited under the Constitution. Following the Constitutional Court's decision regarding pre-censorship on medical ads, there now exists a need to amend the censorship system of advertisements. The Ministry of Health and Welfare is currently planning on an intensive post-monitoring program on illegal medical advertisements as the pre-censorship system has become autonomy. Considering the characteristics of medical ads, a reasonable regulation on medical ads through pre-censorship by autonomous censoring organizations is necessary. Meanwhile, since the regulation on medical ads remains unchanged regardless of pre-censorship, there must be a legal and administrative amendment regarding the future and censorship methods of medical ads and regulations through careful review of the current regulation details and precedent cases.

        Synergistic effects of heat and diatomaceous earth treatment for the control of Plodia interpunctella (Lepidoptera: Pyralidae)

        김한나,유연수,이경열 한국곤충학회 2014 Entomological Research Vol.44 No.3

        Plodia interpunctella is a major economic pest that commonly infests most stored and processed agricultural products. Currently, heating at 50–60°C for at least 48 h is applied in facilities for disinfestation. However, this condition requires a great deal of time and expense. To improve the control efficiency of this system, we conducted combined treatments with heating and diatomaceous earth (DE), which is known to be toxic to pest insects. The DE effect was compared to heating at 25°C or 40°C to wandering fifth instar larvae, which is the stage most tolerant to heat. When larvae were brushed with DE powder, mortality was only 15.0–18.3% at 25°C for 10 days, but rapidly increased to 100% at 40°C within 4 h post‐treatment. In addition, when larvae were kept in a plastic cage with DE [4 mg/L (w/v)], their mortality was 100% in 24 h at 40°C post‐treatment; otherwise mortality was only 8.8% without DE. Thus, the control efficiency of heating significantly improved with the combination of DE. These effects increased further at higher temperatures and with longer exposure. Our results clearly showed that DE treatment showed synergistic effects with heating systems for the control of P. interpunctella.

        위성 OFDMA Downlink에서 PAR을 최소화 하기 위한 사용자 부채널 할당 및 채널 보상 기법

        김한나,최권휴,안도섭,강군석,김희욱,Kim,,Han-Nah,Choi,,Kwon-Hue,Ahn,,Do-Seob,Kang,,Kun-Seok,Kim,,Hee-Wook 한국위성정보통신학회 2009 한국위성정보통신학회논문지 Vol.4 No.1

        본 논문에서는 위성 OFDMA 하향링크에서 PAR을 최소화하기 위한 최적의 사용자 채널 보상기법을 제안한다. 위성 OFDMA 시스템에서는 사용자의 채널 환경에 따른 성능의 저하를 극복하기 위해 사용자의 채널 환경에 따라 전력을 제어하는 PC-OFDMA(Power Control OFDMA) 방식과 변조방식과 코딩방식을 제어하는 AMC-OFDMA(Adaptive Modulation and Coding) 방식을 사용한다. 사용자의 채널 환경에 따라 사용자 부채널(부반송파 그룹)별로 전력을 제어하는, 즉 채널이 좋지 않을 경우 더 큰 출력으로 송신하고 반대의 경우 작은 출력을 송신하는 PCOFDMA와 채널의 상태가 좋지 않은 경우 낮은 변조율과 강한 코딩을 사용하거나 채널이 좋을 경우 데이터율을 높이기 위해 높은 변조율과 약한 코딩을 사용하는 AMC-OFDMA의 PAR 성능을 비교 분석하였다. AMC-OFDMA에서는 변조방식과 부호방식으로 사용자 채널감쇠를 보상하므로 부반송파의 송신전력이 균일하지만 PC-OFDMA의 경우 사용자 부채널별로 전력을 제어하므로 전체 부반송파의 송신전력이 균일하지 않는 특성이 있는데, 부반송파의 불균등 전력은 OFDMA 송신신호의 PAR을 감소시키는 현상을 발견하였다. 또한 PC-OFDMA 방식 중에서 사용자 부채널을 이루는 부반송파의 할당방식에 따라서도 PAR 성능의 차이가 존재함을 보였다. We investigate the adaptive channel attenuation compensation of satellite OFDMA downlink users for minimum PAR (Peak to Average power Ratio), which is one of the main challenging issues in satellite OFDMA application. First, we analyze and compare PAR performances of two main different channel attenuation compensation schemes for OFDMA, i.e., PC-OFDMA (power control OFDMA) and AMC-OFDMA (Adaptive Modulation and Coding). While AMC-OFDMA maintains the constant transmission powers through entire user data subcarriers, PC-OFDMA has non-uniform subcarrier transmission powers because subcarrier powers are separately controlled to compensate each user's sub-channel attenuation. We newly found the fact that non-uniform subcarrier power in PC-OFDMA achieves rather reduced PAR compared to AMC-OFDMA and the amount of reduction becomes larger as the power differences among subcarriers increase. Also, there is an additional PAR reduction in PC-OFDMA by optimizing subcarrier grouping scheme for user's sub-channelization.
