Carcinomas of the stomach can spread to adjacent structure by local extension or metastasize to lymph nodes, peritoneum and distant organs. However, the incidence of metastatic bladder cancer originated at the stomach is very rare. A fifty-five year-old man admitted complaining of epigastric pain for 2 months. A large ulceroinfiltrative lesion was seen in the low body, which was confirmed poorly differentiated adenocarcinoma by histological examination. Abdominopelvic CT scan showed wall thickening at the greater curvature side of gastric body and urinary bladder. Urine cytology was negative. By transurethral resection of bladder, he was diagnosed as metastatic adenocarcinoma of the bladder. We report a case of stomach cancer with metastasis to urinry bladder.

헤스컷 교육연극이론의 구성주의적 조망

Constructivists have criticized the school learning in general not only for its lack of influence in solving problems in the field, but also for its delivering ill-structured and ill-defined knowledge. Accordingly, constructivists have suggested that knowledge should be learned in the context of the real lives. They have also said that learning circumstance should be structured on the basis of active interactions between teachers and students. Their last suggestion was that students should be encouraged to be active participants who enthusiastically construct their own knowledge by themselves. Adopting the ideas of social constructivists, the current study identifies the `educational theatre` as one of the most important constructivist`s educational methods. This study is derived mainly from the educational perspectives of Heathcote, the most recognized expert in educational theatre, because there are many significant similarities between Heathcote`s perspectives and social constructivist`s educational stance. The goals of the educational theatre and education itself are almost identical. It is to foster a whole person. The `growth of understanding` is another expression of educational theatre`s goal. Based on the goal, `fostering the whole person`, Heathcote looks into the role of teachers and that of students first. In an educational theatre teacher and students meet together basically as genuine human-beings. In this humanistic relationship Heathcote has consolidated her student-centered educational ideas. Teachers are to give service and to assist students so that the students could construct their own knowledge by themselves. She considered teachers as midwives. She said that teachers should provide students with an opportunity of being a crucible. Heathcote`s notion of teachers and students is very similar to social constructivist`s perspectives. That is, teachers are mediators while students are active participants in learning. Furthermore, the dialogical relationships between teachers and students are similar to the knowledge-shared process that constructivists put an emphasis on. Having studied the constructivist`s educational stance, it is not an exaggeration to say that the educational theatre is one of the constructivist methods. Heathcote derived her theory primarily from the perspectives of human- and student-centered philosophy. In other words, she, based on the principle of empathy, gave chances to students to experience the `Dual Affect` by placing them into others` shoes. Thus, she created her own unique method, called "Mantle of the Expert". She puts a great emphasis on roles of both teachers and students. Heathcote, however, pays a special attention to students to provide them with real-life-related problems, and to make them solve the problems with their pre-existing knowledge. Students would solve the problems in the `no-penalty zone` of a drama situation. After all, the educational theatre seeks to give students a chance to internalize and to assimilate into the knowledge, not to just make them understand it. Furthermore, Heathcote focused on developing not only intellect, but also emotion. In the sense that both are involved with holistic personality and with the learning through a process of problem-solving in real-life context. To make a long story short, Heathcote`s ideas and methods are in the same veins as social constructivist`s perspectives. We can willingly conclude that the educational theatre is one of the constructivist`s methods.

포인트 적립프로그램의 가입의도에 영향을 미치는 요인에 대한 연구

정성희(Sung Hee Chung),박정은(Jeong Eun Park) 한국마케팅학회 2014 마케팅연구 Vol.29 No.1

본 연구에서는 많은 기업들이 로열티 프로그램의 일환으로 사용하고 있는 포인트 적립프로그램에 대한 가입의도에 영향을 미치는 요인들을 고찰하고자 하였다(Bagchi and Li 2011; Hsee, Yu, Zhang and Zhang 2003; Kivetz, Urminsky, and Zheng 2006). 특히, 구매금액당 적립률 및 제휴가맹점의 수는 가입의도에 중요한 영향을 미치는 요인임에도 불구하고 기존 연구들에서 이런 중요한 변수들이 간과되어 있어 저자들은 이 두 변수들이 포인트 적립프로그램 가입의도에 미치는 영향을 구체적으로 살펴보고자 하였다. 소비자들이 실생활에서 접하는 포인트 적립프로그램은 구매금액당 적립률은 낮으나 포인트를 적립할 수 있는 제휴가맹점들의 수가 상대적으로 많은 경우와 적립률은 높으나 포인트를 적립할 수 있는 제휴가맹점들의 수가 상대적으로 적은 경우로 크게 나누어 볼 수 있을 것이다. 그리고 이런 두 가지 종류의 포인트 적립프로그램에 대해 소비자들이 선호를 평가할 때, 두 변수를 고려하여 선호를 판단하되, 편향된 방법으로 선호판단이 일어날 것으로 예측하였다. 실험 1의 결과, 소비자들은 직접적인 평가를 하는 경우에 포인트 적립률은 낮으나 적립할 수 있는 제휴가맹점의 수가 많은 포인트 적립카드에 상대적으로 더 높은 가입의도를 보였다. 이런 경향은 소비자들이 특정 소수의 제휴가맹점을 자주 이용함을 가정하고 2 종류의 포인트 적립카드에 이들 제휴가맹점이 모두 포함되어 있음을 가정하여도 나타났다. 그러나 적립률 및 제휴가맹점을 고려하도록 유도할 경우에 소비자들은 상대적으로 적립률이 높으나 적립할 수 있는 제휴가맹점의 수가 적은 포인트 적립카드를 선호하는 것으로 나타났다. 실험 2에서는 제휴가맹점의 수가 일정하더라도 제휴가맹점 종류에 대한 카테고리를 많이 분류하느냐 적게 분류하느냐에 따라 소비자가 느끼는 제휴가맹점에 대한 지각된 다양성이 다르게 나타났다. 그 결과, 직접적인 평가를 하는 소비자들은 적립률은 낮으나 제휴가맹점을 많이 분류하여 보여준 포인트 적립카드에 더 높은 가입의도를 보였다. 반면, 적립률 및 제휴가맹점의 이용빈도까지 고려하도록 유도된 소비자들은 적립률이 높고 제휴가맹점을 적게 분류하여 보여준 포인트 적립카드에 더 높은 가입의도를 보였다. This research investigated the factors that influence consumers` intention of joining the loyalty programs (i.e., points card). In particular, the reward points per the amount of purchase and the number of affiliated stores will play important role in determining consumers` intention of joining the loyalty programs. However, these aspects remain explored in existing research. In reality, the typical types of points card may be divided into two: the one that offers higher reward points but with limited number of affiliated stores and the other that offers lower reward points but with a large number of affiliated stores. When consumers evaluate these two types of points card, they may consider two information, but in a biased manner. The results showed that in case of direct evaluations, consumers are more likely to join the points card that offers lower reward points but with a large number of affiliated stores. On the other hand, in case of derived evaluations, consumers are more likely to join the points card that offers higher reward points but with limited number of affiliated stores. Furthermore, we tested the effects of perceived variety of affiliated stores on consumers` intention of joining the loyalty programs. It is expected that consumers will feel differently about the variety of the stores depending on whether the categorization of these stores are detailed or not. The result showed that those participants who were involved in the direct evaluation are more likely to join the points card including lower reward points but with 9 categories of affiliated stores, compared to those participants who were involved in the derived evaluation are more likely to join the points card including higher reward points but with 3 categories of affiliated stores.

항공여정에 대한 시간적 거리감에 따른 메시지 프레이밍 효과

정성희(Chung, Sung-Hee) 한국상품학회 2012 商品學硏究 Vol.30 No.1

해석수준 이론은 시간에 따라 선호가 달라지는 것은 사건에 대한 해석이 상위수준 또는 하위수준으로 이루어지기 때문이라 하였다.(Sagristano, Trope, and Liberman 2002; Trope and Liberman 2003). 최근 이런 효과는 메시지프레이밍에 따라 달라짐을 보여주었다. (White, MacDonnell, and Dahl 2011). 본 연구는 White et al. (2011)의 연구와 달리 바람직성 및 실행가능성 측면에서 서로 상반된 강점을 가지고 있는 옵션에 대한 상대적 선호도를 결정하는 상황하에서 메시지 표현방법의 차별적 효과를 탐구하였다. 실험결과, 가까운 미래를 위해 옵션의 선호를 판단하는 경우에 소비자는 먼 미래의 항공여정을 위해 항공권의 선호를 판단하는 경우 보다 최종상태를 도달하는 방법상의 쉬움과 어려움을 나타내는 실행가능성 측면에서 우월한 항공권을 더 구매하고자 하는 것으로 나타났다. 또한 이런 효과에 대한 메시지 표현방법의 조절효과를 검증한 결과, 먼 미래의 항공여정을 위해 옵션에 대한 상대적 선호 판단 시, 소비자는 메시지 표현방법에 무관하게 최종결과물의 바람직성 면에서 상대적으로 우월한 대안이 더 선호되는 것으로 나타났다. 반면, 가까운 미래의 항공여정을 위해 옵션에 대한 선호 판단 시, 기존연구와 메시지 표현방법에 따라 옵션에 대한 상대적선호도가 다르게 나타났다. 즉, 긍정적으로 표현되는 경우 보다 부정적으로 메시지를 표현할 때, 소비자는 최종결과물의 바람직성이 상대적으로 더 우월한 대안을 더 선호하는 것으로 나타났다. 이는 가까운 미래를 위한 서로 상반된 강점을 가지고 있는 옵션을 비교 판단 시, 상대적으로 덜 중요하게 정보 처리되는 바람직성의 측면이 부정적인 메시지 표현방식일 때 상대적으로 더 중요하게 고려되는 것으로 나타났다. 마지막으로 이 연구의 발견이 갖는 이론적 및 실무적 시사점을 논의하였다. Previous studies of construal level theory noted that consumers' preference over time would be changed depending on different representations (high level vs, low level construl) of same object would cause consumes' preference over time to be changed (e.g., Trope and Liberman 2003; Sagristano, Trope and Liberman 2002). Recent research of White, MacDonnell and Dahl (2011) suggested that loss frames are more effective when paired with low-level, con crete mind-sets, whereas gain frames are more effective when paired with high-level, abstract mind-sets. Present research proposes that in the case of the judgment of options with trade off between the aspect of desirability and feasibility, the effect of temporal distance on options' relative preference would be moderated by message framing. The experiment showed that when the flight is expected in the distant future, consumers preferred superior option in the desirability to in the feasibility. On the other hand, when the flight is expected in the distant future, he effect of temporal distance on options' relative preference was not moderated by message framing. However, when the flight is expected in the near future and options was framed negatively, consumers preferred superior option in the desirability to in the feasibility compared with in the case of positive message framing. The theoretical as well as practical implications are also discussed.

나노기공 표면에서의 세포 행동양식에 관한 연구

정성희(Sung Hee Chung),윤원중(Won Jung Yoon),민준홍(Junhong Min) 한국생물공학회 2012 KSBB Journal Vol.27 No.1

In this paper, we investigated the effect of nanostructure on the cell behaviors such as adhesion and growth rate. Nanoporous structures with various diameters (30, 40, 45, 50, 60 nm) and 500 nm of the depth were fabricated using the anodizing method. The water contact angle of the surface consisting of nanopores with 30 nm diameter was 40 degree and those were 60~70 degree in cases of nanopores with over 40 nm diameter. Hela cells were cultivated on various nanoporous structure surface to investigate the cell behavior on nanostructure. As a result, Hela cells preferred 30 nm diameter nanoporous surface that has lower water contact angle. This result was confirmed by protein adsorption experiment and scanning electron microscope investigation.

초등교육에서 드라마 활용방안 -Synergy 모형을 중심으로

정성희 ( Sung Hee Chung ) 한국초등교육학회 2009 초등교육연구 Vol.22 No.3

본 연구는 Synergy 모형을 중심으로 드라마를 활용한 구성주의 교수학습 방법론을 논의하고 있다. 이는 드라마의 특성이 구성주의 교수학습이론과 일맥상통하기 때문이다. 이때, 드라마는 연극 개념과는 구별되는 것으로 참여자 주도적인 과정 지향적 활동에 초점을 둔다. 따라서, 드라마의 특성은 참여자의 직접적인 참여를 통한 내재적 동기 부여로 인하여 인지적인 근접발달영역의 활성화에만 머무르지 않고, 정의적인 근접발달영역까지 활성화시키는 이상적인 교수학습 방법론이라고 하겠다. 또한 학습자들은 드라마적 행위를 하면서 배우는(Learning by dramatic doing) 경험학습을 통하여 지식을 주체적으로 구성해 간다. 이에 본 연구에서는 초등교육에서 드라마를 활용할 수 있는 구체적인 방안으로 Synergy 모형을 제안하고 있다. Synergy 모형은 다양한 드라마 기법들을 크게 3개의 범주(신체감각훈련, 즉흥극, 극만들기)로 유목화하여, 교과내용, 학습자특성, 제반조건에 맞게 탄력적으로 활용할 수 있다. 그 실례로 초등학교 국어, 도덕, 음악 교과의 수업지도안을 제안하고 있다. This study discusses the constructive teaching/learning methodology, which utilizes drama, centering on a synergy model. It is because characteristics of drama have a lot in common with the constructive teaching/learning theory. However, the concept of drama here differs from the concept of theatre. Drama is more focused on process-oriented activities of the participants, who take initiatives in many cases. Consequently, one would be able to define the characteristics of drama as follows. Drama evokes motivations inside of the participants through their direct participation. Consequently, it is an ideal teaching/learning methodology because it not only activates the proximity development domain of cognition, but also sets in motion the proximity development domain of affection. At the same time the students construct their knowledge independently through the experiential learning called `Learning by Dramatic Doing`. This study presents a synergy model as a specific method of making a practical use of drama in elementary education. The synergy model puts various drama techniques into three different categories: Body-sensory training, Improvisation, and Playmaking. As a result, it can be used in a very flexible way depending upon the lesson-content, student traits, or general condition of education. For practical examples, teaching plans for elementary Korean, Ethics, and Music classes are introduced here.

화학용액증착법에 의하여 증착된 CdS 박막의 특성에 대한 Cd 농도의 영향

정성희 ( Sung Hee Jung ),정지원 ( Chee Won Chung ) 한국공업화학회 2012 공업화학 Vol.23 No.4

CIGS 화합물 반도체 태양전지에서 광흡수층과 상부투명전극 간의 격자부정합을 낮추기 위해 buffer layer로써 CdS 박 막이 적용된다. 높은 광투과도와 낮은 비저항을 갖는 CdS 박막을 제조하기 위하여 화학적 용액 증착법에 의해 반응용 액 내의 S 용액의 농도를 고정하고 Cd 용액의 농도를 변화시켜 CdS 박막을 제조하여 특성을 조사하였다. [S 2- ]/[Cd 2+] 농도비에 따른 박막의 구조적, 광학적 및 전기적 특성을 조사하였다. Cd의 농도가 S의 농도보다 높을 경우에는 균일반 응이 촉진되어 CdS 결정들이 클러스터 형태로 기판에 흡착되어 결정 크기가 증가하고 광투과율이 감소하였다. 반면, Cd의 농도가 S의 농도보다 낮을 경우에는 용액 내에서 보다 기판위에서 CdS 결정입자가 생성되는 불균일반응에 의해 결정이 생성 및 성장되었고 수백 옹스트롱의 작고 균일한 구형 입자가 생성되었다. Cd 농도가 증가할수록 과잉 Cd가 증가하여 S 공극 생성으로 [S 2- ]/[Cd 2+] 조성비는 감소하였고 CdS 박막의 전하 농도가 증가되어 비저항이 감소되었다. CdS thin films have been widely used as a buffer layer of CIGS semiconductor solar cells to reduce the lattice mismatch between transparent electrode and absorber layer. In order to prepare the CdS films with high transparency and low resistivity, they were deposited by varying Cd concentration with the constant S concentration in the solution using chemical bath deposition method. They were analyzed in terms of structural, optical and electrical properties of CdS films according to the [S 2- ]/ [Cd 2+] ratio. In the case of Cd concentration higher than S concectration, CdS thin films were formed mainly by cluster- by-cluster formation due to the homogeneous reaction between Cd and S in the solution. Therefore the grain size increased and the transmittance decreased. On the other hand, in the case of Cd concentration lower than S concentration, CdS films were formed by heterogeneous reaction on the substrate rather than in the solution. The CdS films have the grains with the uniform circular shape of a few hundreds Å. As the Cd concentration increased in the solution, the [S 2- ]/ [Cd 2+] ratio decreased and the resistivity decreased by the increase in the carrier concentration due to the formation S vacancy by the excess Cd.
