온라인 게임에서의 쾌락적 경험에 관한 연구 - 지각된 복잡성의 조절효과를 중심으로 : 온라인 게임에서의 쾌락적 경험에 관한 연구

Lee Jongho(李宗昊),Yunhee Jung(丁允姬) 한국마케팅과학회 2008 마케팅과학연구 Vol.18 No.2

온라인 게임에서의 경험을 설명하는 대부분의 이전 연구들이 플로우의 역할을 강조하고 있으며, 플로우의 선행요인과 결과요인을 밝히는데 초점을 두었다. 플로우는 온라인상의 몰입경험을 설명하는데 타당한 것으로 기존 연구에서 검증되었고 성과와 직결된다는 점에서 중요한 변수임은 분명하지만, 쾌락적 경험으로서의 온라인 게임을 설명하는 데 있어서는 부족하다. 이러한 기존 연구의 부족한 점을 보완하고자, 본 연구는 음악과 영화분야에서 연구된 쾌락적 반응 연구를 온라인 게임에 적용하여 온라인 게임에서의 다차원적인 경험과정을 보여주고자 하였다. 또한 기존에 쾌락적 반응에 관한 연구를 보완하여 감각적 반응, 상상적 반응, 분석적 반응이 감정적 반응에 주는 영향을 검증하였으며, 플로우를 대신해 쾌락적 반응들이 게임 만족에 주는 영향, 게임 만족이 충성도에 주는 영향을 규명하고자 하였다. 그리고 쾌락적 선호를 조절하거나 매개하는 변수로 알려진 지각된 복잡성에 따른 조절 영향을 확인함으로써, 자극의 차이에 따른 쾌락적 반응의 영향차이를 보지 않았던 기존연구를 확장하였다. 연구결과, 감각적 반응, 상상적 반응, 분석적 반응의 감정적 반응에 대한 유의한 영향, 각각의 쾌락적 반응의 만족에 대한 유의한 영향, 만족의 충성도에 대한 영향이 검증되었다. 그리고 이러한 영향은 지각된 복잡성이 다른 집단 별로 달랐는데, 예상한 바대로 지각된 복잡성이 높은 집단에서는 분석적 반응이 전반적으로 강한 영향을, 그리고 낮은 집단에서는 감각적 반응이 감정과 만족에 강한 영향을 주는 것으로 밝혀졌다. 연구 마지막에는 이러한 결과들에 대한 요약 및 해석, 시사점 및 한계점이 논의되었다. Online game researchers focus on the flow and factors influencing flow. Flow is conceptualized as an optimal experience state and useful explaining game experience in online. Many game studies focused on the customer loyalty and flow in playing online game, In showing specific game experience, however, it doesn"t examine multidimensional experience process. Flow is not construct which show absorbing process, but construct which show absorbing result. Hence, Flow is not adequate to examine multidimensional experience of games. Online game is included in hedonic consumption. Hedonic consumption is a relatively new field of study in consumer research and it explores the consumption experience as a experiential view(Hirschman and Holbrook 1982). Hedonic consumption explores the consumption experience not as an information processing event but from a phenomenological of experiential view, which is a primarily subjective state. It includes various playful leisure activities, sensory pleasures, daydreams, esthetic enjoyment, and emotional responses. In online game experience, therefore, it is right to access through a experiential view of hedonic consumption. The objective of this paper was to make up for lacks in our understanding of online game experience by developing a framework for better insight into the hedonic experience of online game. We developed this framework by integrating and extending existing research in marketing, online game and hedonic responses. We then discussed several expectations for this framework. We concluded by discussing the results of this study, providing general recommendation and directions for future research. In hedonic response research, Lacher"s research(1994)and Jongho lee and Yunhee Jung" research (2005;2006) has served as a fundamental starting point of our research. A common element in this extended research is the repeated identification of the four hedonic responses: sensory response, imaginal response, emotional response, analytic response. The validity of these four constructs finds in research of music(Lacher 1994) and movie(Jongho lee and Yunhee Jung" research 2005;2006). But, previous research on hedonic response didn"t show that constructs of hedonic response have cause-effect relation. Also, although hedonic response enable to different by stimulus properties. effects of stimulus properties is not showed. To fill this gap, while largely based on Lacher(1994)" research and Jongho Lee and Yunhee Jung(2005, 2006)" research, we made several important adaptation with the primary goal of bringing the model into online game and compensating lacks of previous research. We maintained the same construct proposed by Lacher et al.(1994), with four constructs of hedonic response sensory response, imaginal response, emotional response, analytical response. In this study, the sensory response is typified by some physical movement(Yingling 1962), the imaginal response is typified by images, memories, or situations that game evokes(Myers 1914), and the emotional response represents the feelings one experiences when playing game, such as pleasure, arousal, dominance, finally, the analytical response is that game player engaged in cognition seeking while playing game (Myers 1912). However, this paper has several important differences. We attempted to suggest multi-dimensional experience process in online game and cause-effect relation among hedonic responses. Also, We investigated moderate effects of perceived complexity. Previous studies about hedonic responses didn"t show influences of stimulus properties. According to Berlyne"s theory (1960, 1974) of aesthetic response, perceived complexity is a important construct because it effects pleasure. Pleasure in response to an object will increase with increased complexity, to an optimal level. After that, with incre

The Semiotics of Self and Narrative Mediation in the Digital Culture : A Self-Portrait as Autobiographical Writing for Consciousness Activity

Lee, Yunhee 고려대학교 응용문화연구소 2012 에피스테메 Vol.0 No.7

Semiotic mediation has recourse to a more advanced technology which leads humans to form a new aspect of life causing the human and technology to become intermingled. As many media theorists indicate, new media with complexity attempts to disguise the nature of technology, resulting in reflecting the very nature of human, closely imitating human in mind and body. This makes us ponder on who we are as humans and what kind of mediational tools we use. In this paper, I will examine three kinds of mediation which are consciousness, social organization, and technology so as to discover self identity in the digital era. I will specifically look into narrative mediation for consciousness activity for human development according to the two intertwined domains of phylogeny and ontogeny. The idea of development in the two directions is apparent in the digital culture in that an individual should not be confined to a subjective world; rather, an individual functions as the representation of universal characters as human beings. Then, how is this individual being defined as in-between character both in private and in public. I suggest a self-portrait as an autobiographical writing describing self identities in the three domains: the personal self in description in reality, the virtual self in a narrated world from the past, and the expressive self as in thought activity for the future. These three selves in an autobiographical writing in cyberspace will illuminate this point.

A Comparison of Reading Test Formats in High School Exams: Multiple Choice vs. Open-ended

Yunhee Lee 서울대학교 언어교육원 2012 語學硏究 Vol.48 No.2

Multiple choice test (MC) and open-ended test (OE) are the most common test formats used in high school exams. To examine the reliability of high school exams, this study investigated the effect of the two different test formats on high school students’ performance. In addition, the students’ preference and perception towards MC and OE were also looked into. The experiment was designed to reflect the real testing situation of Korean high schools and conducted to 129 students in the 10th grade. The participants took either MC or OE and completed the survey so that their scores and answers were compared and analyzed. The results showed that the students got higher scores in MC than in OE regardless of their proficiency levels, and that they preferred MC to OE while perceiving OE to be more valid. The reliability of high school exams was discussed based on the results and the implications for designing the exams and interpreting the scores were addressed.

Sphingobacterium humi sp. nov., isolated from soil

Lee, Yunhee,Jin, Hyun Mi,Jung, Hye Su,Jeon, Che Ok Society for General Microbiology 2017 International journal of systematic and evolutiona Vol.67 No.11

<P> A Gram-stain-negative, facultatively aerobic bacterium, designated strain D1<SUP>T</SUP>, was isolated from soil in South Korea. Cells of strain D1<SUP>T</SUP> were non-motile rods with oxidase- and catalase-positive activities. Growth was observed at 15-40 °C (optimum, 30-37 °C), at pH 5.5-9.0 (optimum, pH 7.0-8.0) and in the presence of 0.0-5.0% (w/v) NaCl (optimum, 0.0-1.0 %). The only respiratory quinone detected was menaquinone 7 (MK-7), and iso-C<SUB>15 : 0</SUB>, iso-C<SUB>17 : 0</SUB> 3-OH and summed feature 3 (comprising C<SUB>16 : 1ω</SUB>7c/C<SUB>16 : 1ω</SUB>6c) were identified as the major fatty acids. Phosphatidylethanolamine was the major polar lipid, and two unidentified glycophospholipids and four unidentified lipids were also detected as minor polar lipids. Sphingolipids, a typical chemotaxonomic feature of the genus Sphingobacterium, were detected. The G+C content of the genomic DNA was 43.6 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain D1<SUP>T</SUP> formed a phyletic lineage with Sphingobacterium hotanense XH4<SUP>T</SUP> within the genus Sphingobacterium. Strain D1<SUP>T</SUP> was most closely related to S. hotanense XH4<SUP>T</SUP> (98.1% 16S rRNA gene sequence similarity) and Sphingobacterium cellulitidis R-53603<SUP>T</SUP> (97.2 %), and the DNA-DNA relatedness level between strain D1<SUP>T</SUP> and the type strain of S. cellulitidis was 43.1±0.7 %. Based on the phenotypic, chemotaxonomic and molecular features, strain D1<SUP>T</SUP> clearly represents a novel species of the genus Sphingobacterium, for which the name Sphingobacterium humi sp. nov. is proposed. The type strain is D1<SUP>T</SUP> (=KACC 18595<SUP>T</SUP>=JCM 31225<SUP>T</SUP>). </P>

Interaction between the p75 neurotrophin receptor and a novel adaptor protein

The neurotrophin plays an important role in the development, differentiation and survival of the nervous system in vertebrates. It exerts its cellular effects through two different receptors, the Trk receptor tyrosine kinase neurotrophin receptor and the p75 neurotrophin receptor, a member of the tumor necrosis factor receptor superfamily. Trk and p75 neurotrophin receptors utilize specific target proteins to transmit signals into the cell. An ankyrin-rich membrane spanning protein (ARMS) was identified as a new p75 interacting protein and serves as a novel downstream target of p75 neurotrophin receptor. We sought to delineate the interaction between p75 and ARMS by deletion constructs of p75 and green fluorescent protein (GFP)-tagged ARMS. We examined the interaction between these two proteins after overexpressing them in HEK-293 cells. Using both Western blot analysis and immunocytochemistry followed by confocal laser scanning microscopy, we found out that the intracellular domain of the p75 neurotrophin receptor was important for the interaction with ARMS. The results from this study suggest that ARMS may play an important role for mediating the signals from p75 neurotrophin receptor into the cell.

<P>This paper reports the use of Au nanoparticles (NPs) as electron transfer bridge layers to improve the photocurrent of viologen/Ru complex-based photoelectrochemical cells. The Ru complex/ viologen/Au NPs on electrodes were prepared using self-assembled monolayers. The cell system showed an excellent photocurrent of 25 nA/cm2 under the 1.5 air mass condition (I = 100 mW/cm2), which is five times greater than Au NPs due to the reduced recombination reaction.</P>

Perception & Needs of Housing Environment for Senior Based on Their Ability of Daily Life in U.S.

Lee, Yunhee(이윤희) 한국주거학회 2018 한국주거학회 논문집 Vol.29 No.5

The purpose of the study was to explore perceptions of older adults with regard to the physical environmental conditions of their housing, difficulties in performing activities in daily life, and intention to remodel the home environment for AIP. The population targeted for this study was adults, ages 60 and over. The age constraint was justified by the aims of the study, which were specific to the relationship between older adults’ in-home daily activities, their physical abilities, and the kitchen and bathroom areas in their homes. The responses were recorded on the printed survey tool to interview about 4560 minutes. The participants in this study included nine men and 22 women ranging in age from 61 to 94 years, and the average age was 76 years. The results were as follows: (1) Most elderly people require bathing-related support products, and need products that support movements that are related to going out and walking, and those that sit and stand up. (2) To assist older adults, accessible products and social services to support bathing and kitchen should be common priorities for elderly-housing designers and developers. AS this study has limitations such as low number of participants, future studies develop questionnaire that focus on the issues above and gather more data for statistical analysis to generalize the information discussed here.

Integration and Evaluation of Clinical Decision Support Systems for Diagnosis Idopathics Pulmonary Fibrosis (IPF)

Yunhee Lee,채영문,Sungwan Jeon 대한의료정보학회 2010 Healthcare Informatics Research Vol.16 No.4

Objectives: The purpose of this study was to develop clinical decision support systems (CDSS) that are integrated with hospital information systems for the differential diagnosis of idiopathic pulmonary fibrosis (IPF). Methods: The integrated CDSS were validated and evaluated by physicians. Knowledge modeling for diagnosing IPF was performed by knowledge working groups, composed of radiologists and respiratory specialists. In order to develop the model for CDSS diagnosis, the clinical cases were collected from 290 cases from Seoul National University Hospital and Sevrance Hospital of Yonsei University. For the evaluation of integrated CDSS, interviews were conducted with respiratory specialists and radiologist 2 weeks after applying CDSSs in clinical settings. The CDSS was integrated with the computer vision system (CVS) and diffuse parenchymal lung diseases (DPLD), CDSS developed in our previous project. Results: Eighteen cases diagnosed as IPF were applied to the collection of diagnostic knowledge and the refined knowledge, the former diagnosed 1 case (6%) and the latter diagnosed 14cases (78%). Therefore, the refined knowledge performed better than collected knowledge. The validation results of integrated CDSSs showed that 81 cases (74.3%) were diagnosed correctly. Conclusions: There were 109 cases of IPF diagnosed and initiated on treatment. The significance of this study is in developing integrated CDSS with PACS by acquiring and redefining the knowledge needed for IPF diagnosis. In addition, it is significant for the integration of CDSS to verification and clinical evaluation.
