Development of hi-technologies occurred fierce competition among companies in the domestic and worldwide. Sometimes the competition has skipped over national boundaries of the countries. This unlimited competition has sparked up an information security war. Therefore the problems of information leakage in key technologies have become a serious issue in the industrial security sector. 'Samsung Electronics Co.'s information leakage incident in 1998 was the beginning of recognition on the concept of keytechnology protection in Korea. In 1998, 'the law of protection on unfair competitions and sales secrets' was enacted and received national concerns. However, the limited punishment provisions and scattered related laws could not show effective power for protecting key technologies. Recently, a complemented legislation has been enacted. 'The law for the prevention and protection of the leakage of industrial technologies' regulates key technology's outflows to the foreign countries, and unlawful information leakages of key technology. The issue of key technology protection is not only management problems of the private companies and individuals, but also protecting national wealth. The purpose of this dissertation is to understanding current protection system of key hi-technologies and critical information leakages, and then to analyze why these problems have been occurred and how to find out the solutions for protecting the key technologies. This study is focusing on the globalized companies and key technologies. Also other countries and private research institutes what they need to protect are in the scope of this study. Industrial scope of the study is manufacturing, distributions, and information technologies. This dissertation approaches the issue from the position of emphasizing preventive/proactive measures against industrial espionage. Because industrial technology outflows by industrial spy could not be predictable. This dissertation has carried out by examining the reports and the analyses, of domestic and foreign literature and relevant agencies on industrial technology. For the realities of industrial technology outflow, this dissertation has examined research papers by the National Intelligence and Small and Medium Business Administration, which are in charge of industrial technology's protection in Korea, and academic periodicals of the relevant members of the academic community. Also relevant agency's websites, magazines, newspaper articles, and statistics have been looked into in order to understand the current industrial technology outflow-related trends. Especially this dissertation is completed policies with the question about how government and relevant agency cooperate against industrial technology outflow. Therefore I suggest some methods to solve the problems against industrial technology outflow. Above all, it is necessary to establish network-system between government institutes or between related institutes in private area, to make these ways effective and to vitalize connection between facilities related with this matter. Especially, to be professional for dealing with the industrial technology outflow, The Korean Association for Industrial Technology Security should check and aid weak point of private area. Furthermore, the government and private agency should expand an protection education of industrial technology, and give consultant on all related companies. In conclusion, the way to protect key hi-technologies and to keep major resources safe from draining out is that the consortium of private-government-institute sector should cooperate and make an effort to seal up national wealth of key technologies. Especially private companies and institutes which are principle defense group should invest their efforts and power more to manage human resources. Because human part is the major sources of information leakage incident.

Chemical processes for the fabrication of spherical silica powder from waste diatomite were developed. Silica component yield leached out from waste diatomite was as high as 80wt% at 100℃ and 60min in 10wt% of sodium hydroxide solution. Aqueous solution of silicic acid was prepared from the aqueous solution of sodium silicate by an ion exchange method. As the face velocity of the aqueous solution of sodium silicate in the ion exchange column increased from 0.5 to 2.0 cm/sec, the sodium ion concentration increased from 10 to 105 ppm. The silica particles were made from the aqueous solution of silicic acid using a ultrasonic spray pyrolysis reactor. The average particle size increased with increasing the air flow of silicic acid. The spherical particles were as small as 800nm at 5ℓ/min.

이재록 水原大學校 大學院 2001 국내석사

적니는 보오크싸이트로부터 수산화알루미늄/알루미나를 제조하는 공정에서 발생되는 강알칼리성의 부산물이다. 본 연구에서는 적니를 여러 가지 조건으로 산처리하여 적니에 포함되어 있는 알루미늄과 철을 침출시켜 액상의 무기응집제를 제조하였다. 적니로부터 Al과 Fe를 최대한 침출시켜 적니응집제를 제조하기 위한 최적조건을 확립하였다. 그 결과, 적니를 황산으로 처리한 적니응집제 A는 적니 10 g을 5 M의 H₂SO₄100 ml와 혼합한 후 85℃에서 24시간 동안 반응시켜 제조하였으며, Al과 Fe의 침출효율은 각각 100%, 86%로 나타났다. 그리고, 적니를 염산으로 처리한 적니응집제 B는 적니 10 g을 9 M의 HCl 100 ml와 혼합한 후 25℃에서 24시간 동안 반응시켜 제조하였으며, Al과 Fe의 침출효율은 각각 75%, 100%로 나타났다. 적니응집제의 응집성능은 합성폐수와 실제폐수에 투입량을 변하시켜 투입한후 여러 pH 값에 대하여 오염물질 제거효율로써 조사하였고, 시판응집제의 제거효율과도 비교하였다. 탁도, 중금속이온(Pb^2+, Cd^2+,Cu^2+, Zn^2+, Cr^3+), 인산염인(PO₄^3--P) 등을 포함하고 있는 합성폐수를 처리한 결과, 적니응집제의 응집성능은 우수하였으며, 시판응집제(Al₂(SO₄)₃, Fe₂(SO₄)₃, FeCl₃)의 응집성능과도 비슷하였다. 또한, 생활하수(탁도, 인산염인)와 도금 폐수(탁도, Pb^2+, Cd^2+,Cu^2+, Zn^2+, Cr^3+)의 실제폐수를 처리한 결과, 응집성능은 우수하였으며, 시판응집제(FeCl₃)의 응집성능과도 비슷하여 실제 현장에 적용할 수 있을 것으로 보여진다. 그리고, 적니응집제를 이용한 석유 화학폐수중의 COD를 처리한 결과, 제거효율은 다소 낮았으나 시판응집제(FeCl₃)보다는 우수하였으며, 응집보조제로서 양이온 고분자응집제 첨가시 가장 효과적인 것으로 확인되었다. 중금속 이온 및 인산염인의 응집 메커니즘을 조사하기 위해 오염물질을 제거율과 플럭의 제타전위를 측정하였고, 슬러지의 탈수성은 무기응집제를 투입하였을 때 발생한 슬러지에 양이온 및 음이온 고분자응집제를 첨가하여 얻은 슬러지의 케익비저항을 구하여 평가하였다. 중금속이온 제거의 경우, 응집 메커니즘은 sweep floc에 의한 체거름 응집임을 확인할 수 있었고, 적니응집제 B를 80 ㎎/L 투입 또는 시판응집제(FeCl₃)를 80 ㎎/L 투입한 후 pH를 11로 조절하여 발생한 슬러지에 음이온 고분자응집제를 첨가하였을 때 최소의 케익비저항(최대의 탈수성)을 얻었다. 인산염인 제거의 경우, 응집 메커니즘은 투입량과 pH 값에 따라 전하중화 및 흡착에 의한 응집 메커니즘이 나타나는 것을 확인하였고, 적니응집제 B를 80 ㎎/L를 투입하여 pH를 6으로 조절한 후 발생한 슬러지에 음이온 고분자 응집제를 첨가하였을 때 최소의 케익비저항(최대의 탈수성)을 얻었다. 적니응집제 B를 제조할 때 발생한 침출 적니슬러지를 재이용하여 펠렛형 흡착제를 제조하였다. 흡착제 제조의 최적 제조조건이 결정되었고, 그 결과, 침출적니 10 g에 카오린 1 g, sodium silicate 용액 2 g을 혼합하여 펠렛화한 후 600℃에서 열처리하여 적니흡착제를 제조하였다. 이렇게 제조한 펠렛형 흡착제는 Pb^2+, Cu^2+, Cd^2+ 등의 중금속 이온에 대하여 우수한 흡착제거율을 보였고, Pb^2+에 대해서는 우수한 탈착율을 보여 재생가능한 것으로 나타났다. Red mud is generated as a by-product during the production of aluminum hydroxide from bauxite ore. In this study the inorganic coagulants were perpared by leaching aluminum and iron from red mud with acids under various experimental conditions. The optimum conditions for leaching aluminum and iron from red mud were obtained. As a result, the red mud coagulant A was perpared by reacting 100 ml of 5 M H₂SO₄solution with 10 g of red mud at 85℃, and the leaching efficiencies of aluminium and iron were 100% and 86%, respectively. The red mud coagulant B was prepared by reacting 100 ml of 9 M HCl solution with 10 g of red mud at 25℃, and the leaching efficiencies of aluminium and iron were 75% and 100%, respectively. The red mud coagulants were tested for their coagulation performance of pollutants in the synthetic, municipal and industrial wastewater. The coagulation performance was compared with that of commercially available coagulants (Al₂(SO₄)₃, Fe₂(SO₄)₃, FeCl₃). As a result, the red mud coagulants were found to have quite a good removal efficiency of turbidity, heavy metal ions (Pb^2+, Cd^2+,Cu^2+, Zn^2+, Cr^3+) and phosphate (PO₄^3--P) in the synthetic watewater. The red mud coagulants were found to have a good removal efficiency of pollutants in the municipal wastewater (turbidity, phosphate phosphorus) and in the plating wastewater (turbidity, Pb^2+, Cd^2+,Cu^2+, Zn^2+, Cr^3+), which was similar to FeCl₃. In the experiment of COD removal in the petrochemical wastewater, the removal efficiency by the red mud coagulants was a little poor, but it was better than that by FeCl₃. The coagulation mechanism was investigated by measuring the removal efficiency of pollutants in the synthetic wastewater and by determining the Zeta potential of their flocs. And the sludge dewaterability was investigated by measuring the specific cake resistance of the inorganic coagulant sludge conditioned with cationic or anionic polymer flocculants. In case of removal of heavy metal ions in the synthetic wastewater, the coagulation mechanism was evaluated to be enmeshment coagulation by sweep floc. When the sludge, generated under the experimental condition that the pH value was adjusted to pH 11 after dosing 80 ㎎/L of the coagulant B or FeCl₃in the synthetic wastewater, was conditioned with an anionic polymer flocculant, the minimum specific cake resistance (the maximum dewaterability) was obtained. In case of removal of phosphate phosphorus, the coagulation mechanism was evaluated to be electroneutralization or adsorption depending on pH value or dosage. When the sludge, generaged under the experimental condition that the pH value was adjusted to pH 6 after dosing 80 ㎎/L of the coagulant B in the synthetic wastewater, was conditioned with an anionic polymer flocculant, the minimum specific cake resistance (the maximum dewaterablilty) was obtained. In order to recycle the leached red mud generated in the process of preparation of the red mud coagrlant B, the pellet type adsorbent was prepared by heat treatment after mixing the leached red mud with kaolin and sodium silicate solution. As a result of the adsorption experiment, it was shown that the pellet type adsorbent made from a mixture of the leached red mud of 10 g, kaolin of 1 g and sodium silicate solution of 2 g at heat treatment temperature of 600℃ had the highest removal efficiency of heavy metal ions (Pb^2+, Cu^2+,Cd^2+). And the desorption experimental result of the pellet type adsorbent was also shown to have a good desorption efficiency of Pb^2+.

이재록 한국체육대학교 사회체육대학원 2021 국내석사

이 연구의 목적은 재활승마 참여 경험이 발달장애아동의 사회성에 미치는 효과를 검증하는 데에 목적이 있다. 연구 대상은 재활승마에 참여 경험이 있는 발달장애아동의 학부모, 또는 법적보호자 122명과 재활승마에 참여하지 않은 발달장애아동의 학부모 또는 법적보호자 64명을 유의표본추출방법으로 선정하였다. 조사도구는 사회성기술 평정척도(Social Skills Rating System: SSRS) 부모용 설문지를 본 연구에 부합하도록 수정, 보완하여 사용하였으며, 자료분석은 SPSS Statistics Version 21 통계프로그램을 이용하여 독립 t-검정, 일원변량분석(one-way ANOVA)를 사용하였다(p< .05). 본 연구에 설정한 연구가설과 제시된 연구결과를 종합하여 얻은 결론은 다음과 같다. 첫째, 재활승마 참여가 발달장애아동들의 사회성기술 발달에 통계적 유의한 차이가 있음을 확인하였다. 둘째, 재활승마 참여 기간에 따른 발달장애아동의 사회성에 미치는 효과는 검증하지 못하였다. 단, 참여기간을 1년 미만과 1년 이상으로만 분석한 결과 사회성기술의 하위영역인 협동요인, 자기주장 요인, 자기통제 요인, 사회성기술 전체로 통계적으로 유의한 차이를 검증하였다. 셋째, 재활승마 참여 빈도에 따른 발달장애아동의 사회성에 미치는 효과는 유의한 차이를 검증하지 못하였다. 이를 종합하여 볼 때, 재활승마 참여 경험이 발달장애아동의 사회성에 전반적으로 효과를 미치는 것으로 나타났고, 1년 이상의 참여 기간이 효과적이라는 것을 검증하였다. 향후 장애아동의 재활승마 참여에 있어 사회성 요인 이외의 보다 다양한 요인의 효과 검증과 다각적인 중재방안들의 후속연구를 진행하는 것이 바람직하다. The purpose of this study is to verify the effect in the experience of participating in riding for the disabled on sociality in disabled children. The research subjects were selected the parents of children with developmental disorder who have the experience of taking part in riding for the disabled or 122 legal guardians, or the parents of children with developmental disability who do not have the experience of joining in riding for the disabled or 64 legal guardians, using a purposive sampling method. A survey tool was modified, supplemented and used SSRS(Social Skills Rating System) as the questionnaire for parents in order to be consistent with this study. Data analysis was used independent t-test and one-way ANOVA by applying SPSS Statistics Version 21 program(p< .05). The following are the conclusions that were obtained by synthesizing the established research hypotheses and the presented findings in this study. First, the participation in riding for the disabled was confirmed to have a statistical significant difference in the social-skill development of children with developmental disorder. Second, the effect on sociality in children with developmental disorder depending on the period of taking part in riding for the disabled failed to be verified. Still, as a result of analyzing the participation duration just with less than 1 year and more than 1 year, a statistical significant difference was proved in a cooperation factor, a self-assertion factor, a self-control factor, the whole social skills, which correspond to sub-spheres of a social skill. Third, a significant difference was not inspected in the effect on sociality in children with developmental disability according to the frequency of participating in riding for the disabled. To sum up, the experience of joining into riding for the disable appeared to have an impact on sociality overall in children with developmental disorder. The participation period in more than 1 year was verified to be effective. In terms of the disabled children’s participation in riding for the disabled henceforth, a follow-up research is desired to be progressed on the verification of an effect in more factors other than a sociality factor and on multilateral interventions.

가스터빈(501F) 연소기 튜닝을 통한 배기가스 저감 및 연소 안정도 확보에 관한 연구

이재록 한양대학교 대학원 2022 국내석사

국내 전력시장에서의 LNG발전 정격용량은 약 32% 및 41.3GW(2020년)이며, 향후 신재생에너지 비중이 확대될 예정임에도 정격용량이 32% 및 55.5GW(2030년)로 지속적으로 늘어날 예정임. 신재생에너지는 기후 조건 등에 따라 발전량 예측이 어려워 전력계통 안정화에 기여하는 바가 낮다. 이러한 여건 속에서 신재생에너지의 백업 발전원으로써 전력계통 안정화를 위한 중요한 역할을 할 것이다. 그렇지만, 대기오염 저감을 위해 가스터빈 배출가스(NOx) 저감이 필요하며, 연소튜닝으로 NOx 배출량을 일정부분 감소시킬 수 있으나 가스터빈 연소 안정도에 영향을 주고 연소진동이 발생할 수 있으며, 연소진동 정도에 따라 가스터빈 고온부품의 수명 감소 및 가스터빈 부품 손상에 대한 방지가 필요하다. 따라서 본 연구에서는 국내에서 많이 운영되고 있는 가스터빈(M501F, 501GAC)에 대한 연소튜닝을 수행하고 그 결과를 토대로 가스터빈별 연소튜닝 특성과 연소튜닝 수행 과정에서의 가스터빈에 미치는 영향을 분석하였다. 본 논문에서는 가스터빈 오버홀 종료 후 20MW~Base Load(약 179MW) 시운전 구간 가스터빈 연소튜닝 중 연료제어밸브(Pilot, Bypass)별 개도율 조정에 따른 연소안정도(CPFM Pressure, Acceleration, BPT Spread) 및 NOx 배출량 변화를 분석하고, 연소튜닝 관련 Control Setting 변경사항 적용 후 최종 Load Swing Test를 통한 연소안정도 및 NOx 배출량이 정상범위를 만족하는지 확인하였다. 주요어 : 연료제어밸브, Band, 연소안정도, 연소여유도, NOx
