SeBo: Secure Boot System for Preventing Compromised Android Linux
김동민,김세원,유혁,Kim, Tong Min,Kim, Se Won,Yoo, Chuck Institute of Embedded Engineering of Korea 2015 대한임베디드공학회논문지 Vol.10 No.6
As the usage of mobile devices becomes diverse, a number of attacks on Android also have increased. Among the attacks, Android can be compromised by flashing a new image of compromised Android Linux. In order to solve this problem, we propose SeBo (Secure Boot System) which prevents compromised Android Linux by guaranteeing secure boot environment for mobile devices based on ARM TrustZone architecture. SeBo checks the hash value of the Android Linux image before the Android Linux executes. SeBo detects all the attacks within 5 seconds. Moreover, since SeBo only trusts the Secure Bootloader from Secure World, SeBo can reduce the additional overhead of checking the Normal Bootloader from Normal World.

음악치료 집단 수퍼비전에서 수퍼바이지가 지각하는 애착유형, 자기효능감, 정서적 유대, 수치심, 평가불안 간의 관계
김동민 한국음악치료학회 2012 한국음악치료학회지 Vol.14 No.1
The purpose of this study was to investigate the relationship among shame, self-efficacy, supervisory relationship, attachment style, and evaluation anxiety in music therapy group supervision. Survey data was collected from 220 music therapists and music therapy students with group supervision experiences, and path analysis was used to investigate the relationship. The results showed that the supervisee’s shame and evaluation anxiety have a causal relationship that is mediated by self-efficacy and moderated by attachment style. 이 연구는 집단 수퍼비전 경험을 가진 국내 음악치료사와 음악치료 석사 학위 과정자로부터 수거한 220 사례를 바탕으로 집단 수퍼비전 상황에서 수퍼바이지가 경험한 수치심, 자기효능감, 애착유형, 수퍼비전 관계, 평가불안 간의 구조적 관계를 경로분석을 통해 검증하였다. 그 결과 수퍼바이지가 지각하는 수치심과 평가불안은 인과관계를 가지며, 이러한 관계에 자기효능감은 매개효과를, 애착유형은 조절효과를 미치는 것으로 나타났다. 수퍼비전 관계는 유의미한 효과를 미치지 않는 것으로 나타났는데, 이는 서양문화에 비하여 상대적으로 위계적 관계가 높은 영향력을 가지는 한국문화와 유관한 것으로 해석된다.

조선조 간행본 『춘추(春秋)』 주해서(註解書)의 특징: 규장각 소장 『춘추』 자료를 중심으로
김동민 서울대학교 규장각한국학연구원 2016 한국문화 Vol.73 No.-
This paper examines trends and distinctive characteristics in publication of commentaries on Chunchu (Four Seasons; Confucian classic) in the Joseon Dynasty. Among commentaries on Chunchu, Chunchugyeongjeonjibhae, published during the reign of King Sejong, Chunchujibjeondaejeon, published during the King Seongjong’s reign, and one of the books published during the King Jeongjo’s reign, Chunchujuasijeon were selected as subjects for this study. These classics’ titles are identical with similar books published in China, yet they are different in structuring and content after redaction. Through this process, shortcomings in format or errors in content of commentaries published in China were corrected, giving birth to a standard text with perfected structure and content. What is worth noticing particularly in this paper is that kings in the Joseon Dynasty ordered in person to publish the commentaries, and put support and efforts at the government level such as their engagement in structuring of the book’s content. This represents a special attention to required readings for a classic study as well as a will to create an independent and standard text on Chunchu. These three commentaries demonstrate the Joseon Dynasty’s academic prowess and achievement.

폴리머 용액법에 의한 In<sub>2</sub>O<sub>3</sub> 첨가 나노 WO<sub>3</sub> 분말 합성 및 NO<sub>2</sub> 가스 센서 특성
김동민,이상진,Kim, Dong Min,Lee, Sang-Jin 한국재료학회 2018 한국재료학회지 Vol.28 No.1
$In_2O_3$ doped $WO_3$ powders were prepared by a polymer solution route and their $NO_2$ gas sensing properties were analyzed. The synthesized powders showed nano-sized particles with specific surface areas of $6.01{\sim}21.5m^2/g$ and the particle size and shape changed according to the content of $In_2O_3$. The gas sensors fabricated with the synthesized powders were tested at operating temperatures of $400{\sim}500^{\circ}C$ and 100~500 ppm concentrations of $NO_2$ atmosphere. The particle size and $In_2O_3$ content affected on the initial sensor resistance in an air atmosphere. The highest sensitivity (8.57 at $500^{\circ}C$), which was 1.77 higher than the sensor consisting of the pure $WO_3$ sample, was measured in the 0.5 mol% $In_2O_3$ doping sample. In addition, the response time and recovery time were improved by the addition of $In_2O_3$.

전극용 Ag Paste의 Cellulose Acetate Propionate(CAP) 개질에 따른 태양전지 효율 향상
김동민,임종찬,김진현,차상호,이종찬,Kim, Dong Min,Lim, Jong Chan,Kim, Jin Hyun,Cha, Sang-Ho,Lee, Jong-Chan 한국재료학회 2018 한국재료학회지 Vol.28 No.4
We investigate the effect of the modification of cellulose acetate propionate as an organic vehicle for silver paste on solar cell efficiency. For the modification of cellulose acetate propionate, poly(ethylene glycol) is introduced to the hydroxyl groups of a cellulose acetate propionate backbone via esterification reaction. The chemical structure and composition of poly(ethylene glycol) functionalized cellulose acetate propionate is characterized by Attenuated total reflectance Fourier transform infrared, $^1H$ nuclear magnetic resonance, differential scanning calorimetry and thermogravimetric analysis. Due to the effect of structural change for poly(ethylene glycol) functionalized cellulose acetate propionate on the viscosity of silver paste, the solar cell efficiency increases from 18.524 % to 18.652 %. In addition, when ethylene carbonate, which has a structure similar to poly(ethylene glycol), is introduced to cellulose acetate propionate via ring opening polymerization, we find that the efficiency of the solar cell increases from 18.524 % to 18.622 %.

A low thermal expansion ceramic, cordierite ($2MgO{\cdot}2Al_2O_3{\cdot}5SiO_2$), was synthesized using pyrophyllite. Pyrophyllite usually consists of $SiO_2$ and $Al_2O_3$, which are the main components of cordierite. $MgCO_3$ and $Al(OH)_3$ were added in various amounts to pyrophyllite and fired for synthesis and sintering. ${\alpha}$-cordierite crystallized from $1000^{\circ}C$ with mixing of 20 wt% $MgCO_3$ and 1.7 wt% $Al(OH)_3$, and un-reacted cristobalite was also detected with the cordierite. As the temperature was increased to $1400^{\circ}C$, the cordierite yield was gradually increased. Powder compacts of the synthesized cordierite were sintered between $1250^{\circ}C{\sim}1400^{\circ}C$; the sintered samples showed a low thermal expansion coefficient of $2.1{\times}10^{-6}/^{\circ}C$ and typical sintering behavior. It is anticipated that it will be possible to synthesize cordierite ceramics on a mass production scale using the mineral pyrophyllite.
