정현아(Hyuna Jung),조현우(Hyunwoo Joe),강수연(Sooyeon Kang),천이진(Yeejin Cheon),김형신(Hyungshin Kim) 한국정보과학회 2012 정보과학회 컴퓨팅의 실제 논문지 Vol.18 No.1

Spacecraft on-board computer (OBC) controls spacecraft's operation. Since flight software on the OBC becomes complex and processors are changing frequently, need for reusing highly reliable flight software inherited from previous missions is increasing. In this research, we developed a virtual machine to improve software reusability for spacecraft. Our virtual machine is similar to Java VM and called as SpaceApp VM. SpaceApp is a simple program executed by the SpaceApp VM. In this paper, we explain on the design and implementation of SpaceApp VM. 인공위성 탑재 컴퓨터는 위성 운영의 핵심 서브 시스템으로 탑재 컴퓨터에 내장되는 비행소프트웨어의 복잡도가 증가하고, 프로세서가 지속적으로 변경됨에 따라 신뢰성이 검증된 기존의 소프트웨어를 재사용하려는 요구가 증가하고 있다. 본 연구에서는 기존에 개발된 탑재소프트웨어의 재사용성을 높일 수 있는 인공위성용 가상머신을 개발하였다. 제안하는 가상머신은 자바 가상머신과 유사하며, SpaceApp 가상머신이라고 부른다. SpaceApp은 SpaceApp 가상머신이 실행시키는 프로그램으로 위성 내에서 자율적으로 동작하는 경량의 비행소프트웨어이다. 본 논문에서는 SpaceApp 가상머신의 설계와 개발에 대하여 설명한다.

Leap Motion을 활용한 증강현실 인터랙션 강화 연구

정현일(Hyun-Il Jung),정형원(Hyung-Won Jung) 한국엔터테인먼트산업학회 2020 한국엔터테인먼트산업학회논문지 Vol.14 No.3

증강현실에 있어서 인터랙션은 중요한 요소이다. 하지만 현재 증강현실 콘텐츠에서 인터랙션 기능은 많이 부족한 실정이다. 현실 환경 정보를 많이 가져오는 것이 증강현실의 발전 방법 중 하나이며, 인터랙션도 자연스레 발전하게 된다. 본 논문에서는 인터페이스 도구로 널리 사용되는 손을 통해 증강현실 환경에서 자연스러운 인터랙션을 위해 Leap Motion을 이용하였고 기존의 디스플레이 터치방식의 한정적인 인터랙션에서 보다 확장시켜 자연스러운 인터랙션을 연출하였다. 이러한 인터랙션의 발전은 추후 증강현실 뿐만 아니라 여러 콘텐츠들의 발전에 기여할 것이다. Interaction is an important component in the sense of immersion in augmented reality. However, the function of interaction in augmented reality contents is very weak. Bringing a lot of real environmental information is one of the ways to develop augmented reality, and interaction will naturally develop. In this paper, Leap Motion was used for natural interaction in augmented reality environment through the hand widely used as an interface tool, and extended more from the limited interaction of conventional display touch methods to create a natural interaction. This development of interaction will contribute to the development of various contents as well as augmented reality later.

Sweet Pumpkin (Cucurbita maxima) is rich in minerals, vitamins, and dietary fibers and has less fat. It is thus effective for dieting and for preventing constipation. Sweet Pumpkin contains vitamin A, particularly beta-carotene, which is turned into retinol in the body and helps protect the vision. It is currently on the spotlight as a vision care, anticancer, and diet food, among others, but because it is hard to find yogurt made of Sweet Pumpkin, in this study, Sweet Pumpkin powder was added to yogurt for promotion as a new health food. Yogurt was made with 0, 0.5, 1, 2, and 3% Sweet Pumpkin powder, and the color properties (brightness, redness, and yellowness), viscosity, pH, and acidity were measured through a sensory test (color, flavor, taste, overall acceptability). The storage stability at five-day intervals for one day, five days, ten days, 15 days, etc. was also experimented on. For the color properties, the greater the amount of Sweet Pumpkin powder added, the greater the decrease in the lightness (L) value, but the redness (a) and yellowness (b) values increased (p<0.001). For the viscosity, it was decreased for five days and then increased by 47-68% for ten days. This showed a significant difference in storage stability period: one day (p<0.001), five days (p<0.01), and ten days (p<0.01) (except 15 days). Further, there was a significant difference in pH and acidity [pH: for one day (p<0.001), five days (p<0.01), and ten days (p<0.01); acidity: one day (p<0.001), ten days (p<0.05), 15 days (p<0.001)]. No significant difference in pH was shown, however, for 15 days, and in acidity for five days. The results of the sensory test are highly estimated in the order of 1%>2%.3%>0%>0.5%. The study results indicate that the addition of 1% Sweet Pumpkin powder is most suitable for manufacturing Sweet Pumpkin yogurt.

부담도의 차이에 의한 사죄행동의 특징에 관한 한일대조연구 -폴라이트니스(politeness)이론의 관점에서-

정현아 ( Hyun A Jung ) 한국일어일문학회 2015 日語日文學硏究 Vol.95 No.1

본고는 부담도가 고(高)저(低)인 사죄장면을 설정하고, 롤플레이 방법으로 수집한 128회화를 분석하여 한일남녀모어화자의 사죄행동의 특징에 초점을 맞추어 폴라이트니스 이론의 관점에서 고찰하였다. 분석결과, 한일남녀모어화자 모두 부담도가 낮은 경우의 사죄장면에서는 사죄내용이 가볍고 심각하지 않기 때문에, 사죄하는 쪽은 자신의 face를 지키고 싶다는 욕구보다는 상대방의 face를 침해하고 싶지 않다는 욕구가 우선되어 “사죄발화문”이 많이 사용되는 경향을 보였다. 하지만, 부담도가 높은 경우의 사죄장면에서는 사죄내용이 무겁고 심각하기 때문에 자신의 face를 지키고 싶다는 욕구와 상대방의 face를 침해하고 싶지 않다는 욕구가 동시에 중요시 되어“사죄발화문”의 사용경향은 줄고 대신 “상황설명발화문”과 “대인배려발화문”이 늘어나는 경향을 보였다. 또한 사죄 받는 쪽은 부담도가 낮은 경우의 사죄장면에서는 상대의 face를 배려하여 사죄내용을 받아들이고 있었다. 하지만, 부담도가 높은 경우의 사죄장면에서는 자신의 face와 상대방의 face를 고려하여 “문제해결발화문”을 많이 사용하였고, 사죄내용을 받아들이는 경우와 받아들이지 않는 경우가 있었다. 그리고 사죄하는 쪽의 “사죄발화문”은 한일모어화자 모두,남성보다는 여성에게서 많이 나타났고 사죄 받는 쪽의 “비난발화문”은 여성보다는 남성에게서 많이 나타나는 공통성을 보였다. 부담도가 높은 경우에는 “상황설명”, “과실수급”, “의향변경”, “비난” 발화문에서 부담도가 낮은 경우에는 “책임관련”, “과실수급”, “비난” 발화문에서 한일간에 의미가 있는 차이점을 보였지만 부담도에 따른 사죄행동에는 한일간에 공통적인 경향도 있다는 것을 시사하였다. The present study set scenes with low and high degree of apology and collected 128 dialogues from the apologetic conversations of Korean and Japanese male and female native speakers, respectively, in role playing setting. And this study examined the characteristics of their apologetic behaviors, focusing on politeness theory. The results showed that both speakers tended to make more ‘apologetic utterances’ in the scenes with light degree of apology, trying not to offend the other’s ‘face’ rather than to defend one’s own face. In the situations with high degree of apology, however, both speakers tended to try to defend both one’s own and the other’s face because it required serious apology, which resulted in the tendency of decreasing ‘apologetic utterances’ but increasing ‘circumstantial explanatory utterances’ and ‘considerate utterances of the other’, instead. On the other hand, the party to receive apology tended to accept other’s apology for considering the speakers’ face in the scenes with light degree of apology. In the situations with high degree of apology, however, the party to receive apology tended to make more ‘problem-solving utterances’ in terms of saving both the speaker’ and his own face. There were both cases that apology was accepted or rejected. In addition, both Korean female speakers and Japanese female speakers, respectively, used more ‘apologetic utterances’ than Korean male speakers and Japanese male speakers when they are on the side of making an apology. Reversely, when they were on the side of accepting an apology, both Korean male speakers and Japanese male speakers, respectively, used more ‘reproaching utterances’ than Korean female speakers and Japanese female speakers.It was found that Korean speakers and Japanese speakers were significantly different from in the utterances of ‘circumstantial explanation’, ‘mistake adjustment’ ‘changing intent’ and ‘reproach’ at the scenes of low degree of apology and in the utterances of ‘responsibility’, ‘mistake adjustment’, and ‘reproach’ at the scenes of high degree of apology. It turned out that both Korean and Japanese share common traits of apologetic behaviors by degree of apology.

반도체 제작 시 포토리소그래피 공정은 설계한 전기회로패턴을 기판 위에 옮기는 공정이다. 기판에 가공된 패턴이 설계한 전기회로와 정확히 일치하게 전사되었는지의 여부는 반도체 고집적화 연구에서 매우 중요하며, 주로 AFM, FE-SEM, Alpha Step, CIRCLTM Suite 등의 장비를 이용하여 검사한다. 본 논문에서는 디지털 홀로그래피를 이용한 검사 방법을 제시하였다. 이를 위해 포토리소그래피 공정으로 허니컴 패턴이 제작된 반사형 시험대상체 상에 임의로 9곳의 측정점을 지정하였다. 반사형 디지털 홀로그래피를 이용하여 허니컴 패턴으로 제작된 회로의 선 폭을 측정하고, 그 결과로부터 회로가 설계한대로 정확히 전사되었는지 여부를 확인하였다. 반사형 디지털 홀로그래피로 측정한 결과값의 신뢰성을 확인하기 위하여 통상적으로 쓰이는 검사장치인 AFM과 FE-SEM으로 측정하여 그 결과를 비교, 검증하였다. During semiconductor fabrication, the photolithography process is a transfer printing process used to replicate the designed electric circuit pattern onto a wafer or circuit board. For studies related to high integration of semiconductors, it is very important to confirm whether the printed pattern is fabricated with complete fidelity. AFM, FE-SEM, Alpha Step, and CIRCLTM Suite are typically used systems for inspecting the printed pattern. In this paper, an inspection method using digital holography is proposed. For this purpose, nine measuring points on a reflective object, which the honeycomb pattern in the photolithography process was printed on, were selected arbitrarily. The line width of the honeycomb pattern printed on the wafer was measured using the reflection type of the digital holography. Subsequently, it was confirmed whether the pattern was correctly printed or not. In order to verify the reliability of the reflection type of the digital holography, the results of the digital holography were compared with those of AFM and FE-SEM, and it was confirmed that the deviation from AFM and FE-SEM was within 3% and 0.5%, respectively.

상호작용에 있어서의 사죄행동에 관한 한일대조연구 - 한일남녀모어화자의 사용경향을 중심으로 -

정현아 ( Hyun-a Jung ) 한국외국어대학교 일본연구소 2015 日本硏究 Vol.0 No.64

본연구는, 정신적인 피해를 준 경우의 사죄장면을 설정하여 한일남녀모어화자의 “사죄”라는 언어행동의 상호작용의 특징을 밝히는 것을 목적으로 한 것이다. 조건통제를한 한일남녀모어화자의 대학생 친구간의 64회화를 분석대상으로 하였으며, 그 결과는 아래와 같다. 한일남녀모어화자의 사죄하는 쪽은, 주로 “상황설명, 사죄, 책임관련, 대인배려발화문”을 사용하며, 사죄 받는 쪽은, 주로 “사태확인, 비난, 양보, 문제해결발화문”을 사용하여 문제가 되는 내용을 해결하기 위하여 서로 적극적으로 상호작용을 행하고 있었다. 특히 한국어모어화자는 사죄하는 쪽이 “과실수급발화문”을 많이 사용하는 경향이 보였다. 그러나 한국남성은 한국여성보다, “책임관련발화문”과 “비난발화문”을 많이 사용하였고, 한국여성은 한국남성보다 “상황설명, 대인배려발화문”과 “양보발화문”을 많이 사용하였다. 특히 한국여성은 대안(代案)을 제시하는 “과실수급발화문”을 많이 사용하고 있기 때문에 사죄내용이 사죄 받는 쪽에게 받아들여지는 회화가 많이 나타나는 특징이 보였다. 한편, 일본남성은 일본여성보다, “상황설명발화문”과 “비난발화문”을 많이 사용하였고, 일본여성은 일본남성보다, “사죄, 대인배려발화문”과 “사태확인, 양보, 문제해결발화문”을 많이 사용하였다. 즉, 여성 쪽이 상대의 face를 배려하는 발화문을 많이 사용하는 경향이 있고, 남성 쪽이 상대의 face를 침해하는 발화문을 보다 많이 사용하는 경향이 나타났다. The present study aimed to compare the similarity and difference of ‘Apologetic behaviors’ in interaction, using 64 conversations between college friends of Korean male and female native speakers and Japanese male and female native speakers, respectively. Both Japanese and Korean male and female native speakers that are obliged to apologize mainly used ‘utterances of situational explanation, apology, accountability and/or interpersonal consideration’ while those worthy apology mainly used ‘utterances of situation confirmation, blame, concession and/or problem solving’. In detail, Korean native speakers who have to apologize mainly used ‘utterances of mistake adjustment’. In apologetic interaction, in addition, Japanese male native speakers more used ‘utterances of situational explanation’ and ‘utterances of blame’ than Japanese female native speakers while Japanese female native speakers more used ‘utterances of apology and interpersonal consideration’ than Japanese male native speakers. In the meantime, Korean male native speakers showed apologetic interaction of using more ‘utterances of accountability’ and ‘utterances of blame’ than Korean female native speakers while Korean female native speakers more used ‘utterances of situation explanation and/or interpersonal consideration’ and ‘utterances of concession’ than Korean male native speakers. Particularly, Korean female native speakers used ‘utterances of mistake adjustment’ very often by proposing an alternative, so they had more conversations that accept apology. That is, it was found that females had tendency to more use considerate utterances for the other party’s face while males tended to use utterances of hurting the other party’s face more.

정현아(HyunA Jung),황진영(Jinyoung Hwang) 대한전자공학회 2018 대한전자공학회 학술대회 Vol.2018 No.6

Band alignment transition from type I to type II of InP/In0.48Ga0.52P quantum dots (QDs) is observed by modifying the geometrical factors of the dome-shaped QDs. Strain distribution in InP/InGaP QD is calculated using a valence force field (VFF) model. With the strain Hamiltonian from the VFF model, electrical structures of the QDs are obtained using 8-band k.p model. The results from the theoretical study show that the band alignment of the InP/In0.48Ga0.52P QDs can be tailored from type I to type II by controlling the size of the QDs, and flat valence band can be achieved at certain values of height and width of the QDs. In addition, InP/In0.48Ga0.52 QDs of various sizes with the same effective bandgap but different band alignment are observed.
