This article examine the relation between Korea’s division system and the films of Shin Sang-ok, who was one of very famous Korean film directors in the golden age of Korean cinemas. Shin Sang-ok has been maybe the only Korean director, who produced his films in two Koreas. Before he was kidnapped by North Korean kidnap gangs, he was an outstanding film director in South Korea, who produced several popular films, as like 〈A Romance Papa〉, 〈King Yeonsan〉, 〈the evergreen tree〉, 〈a guest and mother)〉, 〈the Red muffler〉, and so on. Also, He managed the biggest film company ‘Shin Film’ and the biggest film studio ‘Anyang Film Studio’ in South Korea in 1960s, he maintained to good relation with the president Park Chung-hee’s government at that time. However, as Shin criticized the film policy of Park Chung-hee’s government, especially the problem of film censorship, the conflicts between them went to worse way in 1970’s. And then Shin was kidnapped with his ex-wife a famous Korean film actress Choi Eun-hee to North Korea. Shin abd Choi stayed in there during the 8 years and produced 7 films in North Korea’s Monolithic Ideal Logical System by Kim Jung-il’s enforcement and immense supports. At that time, Shin produced several remarkable films in North Korea, as like 〈not returned the emissary〉, 〈the salt〉, 〈a story of the escape〉. Finally, Shin and Choi escaped from North Korea for obtaining the freedom to the Western world. Two Koreas’s division system brought the restriction of creative film making to a film director Shin Sang-ok.

물리화학적 처리를 이용한 군부대 사격장 내 중금속 오염 토양의 정화

이상우,이우춘,이상환,김순오,Lee, Sang-Woo,Lee, Woo-Chun,Lee, Sang-Hwan,Kim, Soon-Oh 한국지하수토양환경학회 2021 지하수토양환경 Vol.26 No.5

This study evaluated the feasibility of combined use of physical separation and soil washing to remediate heavy metals (Pb and Cu) contaminated soil in a military shooting range. The soils were classified into two types based on the level of heavy metal concentrations: a higher contaminated soil (HCS) with Pb and Cu concentrations of 6,243 mg/kg and 407 mg/kg, respectively, and a lower contaminated soil (LCS) with their concentrations of 1,658 mg/kg and 232 mg/kg. Pb level in both soils exceeded the regulatory limit (700 mg/kg), and its concentration generally increased with decreasing soil particle size. However, in some cases, Pb concentrations increased with increasing soil particle size, presumably due to the presence of residues of bullets in the soil matrix. As a pretreatment step, a shaking table was used for physical separation of soil to remove bullet residues while fractionating the contaminated soils into different sizes. The most effective separation and fractionation were achieved at vibration velocity of 296 rpm/min, the table slope of 7.0°, and the separating water flow rate of 23 L/min. The efficiency of ensuing soil washing process for LCS was maximized by using 0.5% HCl with the soil:washing solution mixing ratio of 1:3 for 1 hr treatment. On the contrary, HCS was most effectively remediated by using 1.0% HCl with the same soil:solution mixing ratio for 3 hr. This work demonstrated that the combined use of physical separation and soil washing could be a viable option to remediate soils highly contaminated with heavy metals.

중국 데이터 보안체계 구축에 관한 연구 - 데이터안전법 심의과정에서의 쟁점사항을 중심으로 -

이상우(Lee, Sang-Woo) 영남대학교 중국연구센터 2021 중국과 중국학 Vol.- No.44

현재 전(全)세계적으로 약 100여 개 국가⋅지역에서 데이터 안보와 관련된 법률을 제정하였으며, 데이터 안보에 관한 특별 법안은 국제 관행이 되었는바, 중국 당국도 빈번해지는 국경 간 데이터 흐름 속에서 자국의 국익, 기업과 개인의 이익을 보호하기 위한 중국의 데이터 보안체계 구축의 필요성이 대두되었다. 이와 같은 배경 아래 중국 공산당 중앙위원회는 데이터 안전을 강화하고 디지털경제 발전을 촉진하기 위한 일련의 조치를 취하였으며, 전국인민대표대회 상무위원회는 데이터 보안체계를 구축하기로 한 중앙위원회의 요구사항에 따라 데이터 보안 관련 입법을 적극 추진하게 되었다. 2020년 7월 3일 「데이터안전법(초안)」이 공개된 이후 세 번의 심의과정을 거쳐 2021년 6월 10일 13기 전국인민대표대회 상무위원회는 제29차 회의에서 「데이터안전법」을 최종 통과시켰다. 「데이터안전법」은 데이터 분야의 기본법이자 국가안보 분야의 중요법률로서 2021년 9월 1일부터 시행 중이다. 총 7장, 55개 조항으로 구성된 「데이터안전법」」은 초안의 기본 골자를 그대로 유지하고 있으나, 몇 가지 쟁점사항과 관련한 조항은 세 차례 심의를 거치면서 치열하게 논의되었고, 최종 수정⋅보완 및 신설되었다. 이에 본고에서는 초안의 데이터 안전 보호를 위한 중점제도를 분석했던 선행연구(이상우 2021, pp.451-501)를 기반으로 하여, ① 초안의 51개 조항이 심의과정에서 어떠한 수정작업을 거쳐 최종안의 55개 조항이 되었는지를 검토⋅분석해보고, ② 주요쟁점사항과 관련한 상무위원회 위원들의 견해와 입장을 살펴보도록 하겠다. 중국과 우리나라, 양국 모두 빅테크 기업이 주도하는 데이터 기반의 디지털경제 활성화와 데이터 보안 강화라는 공통된 과제를 가지고 있는바, 심의과정을 살펴 앞으로의 중국 데이터 보안체계를 전망해 보고, 쟁점사항에 대한 중국 입법기관의 고민을 이해하는 기회로 삼아 우리나라 관련 입법에의 시사점을 도출해 보는 것에 의의를 두고자 한다. About 100 countries and regions around the world have enacted laws related to data security at the moment. Special legislation on data security has become an international practice. The Chinese authorities need to build a data security system to protect their national interests and those of companies and individuals amidst the cross-border data flow. Against this background, the Central Committee of the Communist Party of China has taken a series of measures to strengthen data security and revitalize the digital economy. The Standing Committee of the National People’s Congress actively promoted legislation related to data security in accordance with the requirements of the Central Committee of the Communist Party of China to build a data security system. After the 「Data Security Law(draft)」 was released on July 3, 2020, it went through three deliberation processes. On June 10, 2021, the 「Data Security Law」 was finally passed at the 29th meeting of the Standing Committee of the 13th National People’s Congress. The 「Data Security Law」 is a basic law in the data field and an important law in the field of national security, and became enforceable beginning September 1, 2021. The 「Data Security Law」, which consists of 7 chapters and 55 articles, maintains the basic gist of the draft. However, the provisions related to several issues were debated fiercely after going through three deliberation. It was finalized and supplemented. This article is based on a previous study(Lee, Sang-Woo 2021, pp.451-501) that analyzed the draft for a system of data security protection. This article will ① review and analyze how the 51 articles of the draft went through the deliberation process to become the 55 articles of the final version, and ② examine the views and positions of the members of the Standing Committee on major issues related to data security. Both China and Korea have the common task of revitalizing the data-based digital economy led by big tech companies and strengthening data security. Therefore, this article will look at the deliberation process and predict the future of China’s data security system. In addition, it will be meaningful to understand the concerns of the Chinese legislative body regarding the issues and to draw implications for the related legislation in Korea.

In this paper, the ac breakdown characteristics of pure Ar, Kr and $N_2$ gas with gas pressure range of 58.8-137.3[kPa] under uniform and non-uniform fields were investigated, and the measured values were compared with those In Ar/$N_2$ and Kr/$N_2$ gas mixtures with pressure varying. Summarizing the experimental results, the breakdown voltages of Pure $N_2$gas, under uniform and non-uniform fields, were increased about 4.8 and 1.1 times than those of pure Ar gas, and about 4.4 and 1.2 times than those of pure Kr gas, and the ac breakdown voltage increased with the pressure increasing. The breakdown voltages of Ar/$N_2$ gas mixtures were decreased with decreasing the mixture ratio of Pure $N_2$ gas. In case of Ar(85%)/$N_2$ (15%) and Ar(70%)/$N_2$ (30%) gas mixtures comparing to the pure Ar gas, the breakdown voltages under uniform field were increased about 1.8 and 2.2 times, and under non-uniform field were increased about 1.1 and 1.3 times at the pressure of 101.3[kPa]. Also, in case of Kr(85%)/$N_2$ (15%) and Kr(70%)/$N_2$ (30%) gas mixtures comparing to the pure Kr gas, the breakdown voltages under uniform field were increased about 1.7 and 2.0 times, and under non-uniform field were increased about 1.0 and 1.2 times. Corona inception voltage of Kr(70%)/$N_2$(30%) gas mixtures under non-uniform fields were increased about 1.28 times than those of Ar(70%)/$N_2$ (30%) gas mixtures. In case of practical incandescent lamps, luminous and lifetime of Kr(70%)/$N_2$ (30%) gas mixtures were increased about 1.15 and 1.21 times than those of Ar(70%)/$N_2$ (30%) gas mixtures.

In recent years, understanding the dynamics of DC distribution system has become critically important due mainly to the increasing needs for the interconnection of DC distributed generators and the (DC-based) electric vehicle (EV) charging systems. In this paper, the characteristics of the DC grid system connected to the compact proton exchange membrane fuel cell (PEMFC) has been studied. In particular, the voltage and current transient phenomena were measured by varying the load of the DC grid system. Also, the voltage and current ripple were measured at the different load conditions. Our experimental results clearly manifested that the study contributes to the establishment of fundamental method to characterize the small DC grid system including distributed generation.

본 연구는 대구광역시의 주요도로를 대상으로 공간통계기법을 이용하여 도로교통 온실가스 배출량을 신뢰성있게 예측하여 추정된 배출량으로 행정구별에 따라 도로교통에서 발생한 온실가스 배출량을 산정하는 것을 목적으로 하였다. 첫째, 주요도로의 교통량 관측지점에서 실시간으로 조사한 교통량을 이용하여 관측지점에서 발생한 온실가스 배출량을 산정하였다. 둘째, 일반 크리깅(Universal Kriging)기법을 이용하여 공간적 상관성에 의해 미 관측지점의 온실가스 배출량을 신뢰성 있게 추정하기 위해 적합한 베리오그램 모델링을 설정하였다. 이에 교차검증을 통하여 적합한 베리오그램 모델과 크리깅 기법의 타당성을 검증하였다. 셋째, 검증된 크리깅 기법으로 미 관측지점의 도로교통에서 발생한 온실가스 배출량을 예측하여 행정구별로 도로교통 온실가스 배출량을 추정하여 산정하였다. 그 결과, 도로교통 온실가스 배출량을 행정구별로 보면 북구가 약 $291,878,020kgCO_2eq/yr$로 가장 많은 온실가스를 배출하는 것으로 나타났다. This study was intended to reliably predict the traffic green house gas emission in Daegu with the use of spatial statistical technique and calculate the traffic green house gas emission of each administrative district on the basis of the accurately predicted emission. First, with the use of the traffic actually surveyed at a traffic observation point, and traffic green house gas emission was calculated. Secondly, on the basis of the calculation, and with the use of Universal Kriging technique, this researcher set a suitable variogram modeling to accurately and reliably predict the green house gas emission at non-observation point suitable through spatial correlation, and then performed cross validation to prove the validity of the proper variogram modeling and Kriging technique. Thirdly, with the use of the validated kriging technique, traffic green gas emission was visualized, and its distribution features were analyzed to predict and calculate the traffic green house gas emission of each administrative district. As a result, regarding the traffic green house gas emission of each administration, it was found that Bukgu had the highest green house gas emission of $291,878,020kgCO_2eq/yr$.

다요인 모형을 이용한 한․중 주식수익률 결정요인의 비교 *

이상우(Lee, Sang-Woo),이의경(Lee, Eui-Kyung) 글로벌경영학회 2012 글로벌경영학회지 Vol.9 No.3

This study examines an effect of macro economic factors on the Korea and China stock return using multi-factor model based on APT. The study period is from the ten years from 2001 to 2010. The macro economic factors are classified into two groups, financial factors and real factors. The former consists of two variables, interest rate and foreign exchange rate. The real factors consist of two variables, economic growth rate and oil price increase rate. This empirical analysis of Korea and China stock returns showed the following results. First, Korea stock return is mainly affected by financial factors and economic growth rate. But China stock returns are affected by oil price. Second, foreign exchange rate had different sign in affecting on Korea and China Stock returns. Third, this research model is fit to China before the global financial crisis and Korea after global financial crisis. The evident differences between Korea and China stock may explain the reason why the prior studies could not find the coupling between Korea and China stock market. And they show some implications to those who are interested in China stock market. 본 연구는 APT에 기반을 둔 다요인 모형을 이용하여 주식수익률과 거시경제변수들의 관계를 분석한 것이다. 2001년부터 2010년까지의 10년 기간을 대상으로 한국은 KOSPI를, 중국은 상해종합주가지수를 통해 산출한 월별 주식수익률과 금융변수(금리와 환율), 실물변수(경제성장률, 국제유가)들과의 관계를 분석하였다. 분석결과를 비교하여 두 국가 주식수익률 사이의 다음과 같은 차이점을 발견하였다. 첫째, 한국의 경우에는 경제성장률, 환율, 금리 등이 주식수익률에 중요한 영향을 미치는데 비해서 중국의 경우에는 국제유가의 변화가 주식수익률에 중요한 영향을 미치고 있다. 둘째, 두 국가 모두 금리는 음(-) 의 관계를, 경제성장률과 유가상승률은 양(+)의 관계를 갖지만 환율의 경우에는 한국은 음(-), 중국은 양(+)의 관계를 보였다. 셋째, 2007년 글로벌 금융위기를 기준으로 그 이전과 이후 기간에 대해 분석한 결과, 본 연구모형은 글로벌 금융위기 이전의 중국과 글로벌 금융위기 이후의 한국에 적합한 것으로 나타났다. 이러한 뚜렷한 차이점은 학문적으로는 그 동안 선행연구들이 한국과 중국의 증시동조화를 확인할 수 없었던 원인을 설명하는 단서가 될 수 있다. 또한 실무적으로는 중국증시에 투자하거나 중국증시 에서 자금을 조달하는 경우 중요한 고려변수를 제시하는 결과가 될 수 있다고 생각된다.

XLPE 절연체의 트리 채널내 보이드방전에 의한 AE신호로 절연열화 검출 기법 연구

이상우,Lee, Sang-Woo 한국조명전기설비학회 2006 조명·전기설비학회논문지 Vol.20 No.2

본 논문은 전력 케이블의 절연체인 XLPE 시료에 상용주파수 교류전압을 인가하였을 때, 절연열화에 의한 보이드방전 펄스신호와 AE신호 및 트리진전 특성을 검출하고 관찰하였다. 또한 XLPE 절연체의 트리 채널내 인가전압에 따라 보이드방전 펄스신호와 AE신호를 각각 관측하였다. 실험 결과 전력 케이블의 절연체인 XLPE 시료의 보이드 존재 유 무에 따른 트리진전 형상은 보이드 존재시에는 수지형으로 성장하였으나, 무보이드시에는 수초형으로 성장하였다. XLPE 절연체내의 트리진전 특성은 보이드 존재시에는 열화시간이 경과함에 따라 급격히 증가하였으나, 무보이드시에는 열화 시간이 경과함에 따라 트리의 성장 형상은 감소되는 것으로 나타났다. 전력 케이블 절연체인 XLPE의 트리 채널내 보이드방전에 의한 AE신호의 주파수 스펙트럼으로 분석한 결과, AE신호의 크기에 따라 변화되었으며 그 주파수 영역은 대략 1.0[MHz] 이하의 분포인 것으로 관측되었다. In this paper, to detect and observation the void discharges pulse signal, AE signals and tree growth characteristics in case the high voltage is applied to a XLPE sample for a power cable. We also examined the partial discharge current pulse and AE signals with the increase of the applied voltage in XLPE insulation. The experimental results show that a branch-type tree grows in the presence of the voids, and a bush-type tree grows in the absence of the voids in both samples. A rate of tree growth increases abruptly in proportional to the deterioration time in the presence of the of the voids, but in the absence of the voids, a rate of tree growth decreases as time goes by and finally a breakdown occurs. The frequency band of AE signals that are generated from the partial discharges in a XLPE sample, one of solid dielectric materials, is about 1.0[MHz].

이상우,김갑기,Lee, Sang-Woo,Kim, Kab-Ki 한국정보통신학회 2007 한국정보통신학회논문지 Vol.11 No.1

본 논문은 Top-loading한 슬리브 모노폴에 4개의 Post 형태 기생소자를 추가함으로써, 기존의 상용 이동통신 시스템의 주파수를 하나로 통합 할 수 있는 소형이면서, 광대역 특성을 갖는 모노폴 안테나를 설계 및 제작하였다. 각 소자의 Parameter 변화에 따른 반사손실 특성을 관찰하였고, 제안된 안테나의 광대역 특성을 확인하기 위하여 PCS, W-CDMA, WiBro, W-LAN, S-DMB 대역에서의 복사 특성을 살펴보았다. 제안된 안테나는 수평면내 무지향성, 수직면내 8자형의 지향성을 가지며 $1.67{\sim}3.55\;GHz$ 주파수 대역($B/W{\fallingdotsep}72%$) 에서 Return loss$Return\;loss{\leq}-10\;dB$의 양호한 반사손실과 $1.14{\sim}3.66\;dBi$의 이득을 얻을 수 있었다. In this paper, we have designed and fabricated a small size wide-band monopole antenna which can integrate the frequency of previous business mobile communication system by adding 4 PCS of post type parasitic element on top-loaded sleeve monopole antenna. We have observed the properties of return loss upon a parameter change of element, and we also examined radiation properties in the band of PCS, W-CDMA, WiBro, W-LAN and S-DMB in order to make sure the suggested antenna's wide-band properties. We have found that the proposed antenna has omni-direction in horizontal plane and figure eight-direction in vertical plane, and we could have good return loss($Return\;loss{\leq}-10\;dB$) and $1.14{\sim}3.66\;dBi$ gain in $1.67{\sim}3.55\;GHz$ of frequency range($B/W{\fallingdotsep}72%$).
