  • This paper analyzes qualitatively the stereo 3D content factors causing viewer's discomfort. For this, we perform a subjective test that each subject strokes a specific key whenever he (she) feels discomfort during watching a stereo 3D contents. Also we extract the data for the factors in the 3D contents to obtain their quantitative values and the amounts of the temporal changes. Those two sets of data are used to analyze the contents to find the factors which cause viewer's discomfort. The factors to be considered are the amount and the frequency of the disparity changes, story of the contents, situation or environments of a scene, movement and the position of the camera, color and luminance information as well as disparities themselves. We analyse the various strong and weak factors and their composites to find how much discomfort each factor or composite causes. We also show the situations and their related factors that causes less discomfort than the amount of their disparities.

  • When a human operator interacts with a virtual wall that is modeled as a virtual spring model, the lager the stiffness of the virtual spring is, the more realistic the operator feels that the virtual wall is. In the previous studies, it is shown that the maximum available stiffness of a virtual spring to guarantee the stability can be increased when the first-order-hold method is applied, however the effects of a human impedance on the stability are not considered. This paper presents the effects of a human impedance on stability of haptic system with a virtual spring and a first-order-hold (FOH) method. The human impedance model is modeled as a linear second-order system model. The relations between the maximum available stiffness of a virtual spring and the human impedance such as a mass, a damping and a stiffness are analyzed through the MATLAB simulation. It is shown that the maximum available stiffness is proportional to the square root of the human mass or damping respectively.

  • This paper aims at investigating the characterization and author's consciousness of Okhwangibong written in about 18th century in Korea. Okhwangibong deals with the historical event in the Later Han of ancient China, that is to say the Empress Gwak's banishment and the royal harem Eum's accession to the queen consort. The author of this work created the focal characters freshly. Particularly Gwak is characterized as the vivid woman who desires the Emperor Kwangmu's love, reproaches his negative attitude toward her wants, and feels pains by reason of his affection to Eum. The author intended to justify Eum's accession to the queen consort through emphasizing Providence and her virtue. But the author's intention could not be realized fully. Because what is called Providence was lost persuasive power, and Gwak was characterized very affirmatively. Therefore it can be said that this work represents Gwak's trials and pains caused by Kwangmu. And the discord of the author's intent and the real meaning of the work occurred the dispute about affection and faithfulness between man and wife in following novels. Consequently the historical meaning of Okhwangibong in Korean Novel can be founded in successful characterization and occurring the dispute in following novels.

  • An ischemic heart disease(IHD) is a anemic state of heart caused by disproportion between heart's demand and supply of oxygen. A patient who has this IHD feels serious chest pain called angina pectoris. In a keen condition it leads to a necrosis of heart muscles, known as myocardial infarction. In an ischemic heart disease the ECG waves gives us useful information of patients' heart. And CK(creatine kinase) in serum and Troponin T are the principal factors in diagnosis of IHD. In this study, the IHD patient classified by Sasang Constitutional Medicine had a notable medical effects. The symptoms of patient are disappeared and waves of ECG is closed to normal. The result of CK in serum is also recovered. So we report the healing process and results of this patient in this study.

  • The present lecture aims to discuss Nietzsche's critique of metaphysics, religion and morality through the affect. Nietzsche's philosophical attempt for the existential health of man made possible by the affirmation of the earth as a world of realistic life. The affirmation about the nascent Earth means that one feels the world as a world of pleasure. But metaphysics and religion have imagined the earthly world of this world as a place against lust. That is, metaphysics and religion suppress the actual affect of man. From the aspect of metaphysics, religion and morality, the human affect is dangerous. But according to Nietzsche, affect is the basic condition revealed by man's nature. The present lecture aims to discuss Nietzsche's critique of metaphysics, religion, and morality in the guide to his concept of affect.

  • In this study, the odor of the parts and the odor of the surrounding environment were classified and verified. In order to increase the reliability of odor quantitative/qualitative analysis, the selection criteria for 5 sensory evaluators were established, and the n-Butanol control solution for each odor intensity was periodically trained to recognize the odor intensity before sensory evaluation. In addition, although various odor thresholds have been used through several studies, verification of whether the odor intensity value obtained through GC/MSD analysis is similar to the degree to which a person directly smells and feels it. It is important to select the odor threshold that has the best correlation with the odor intensity calculated by the person smelling the odor. Finally, sampling and measuring flowing airflow and temporary odors such as odor component analysis was experimentally difficult due to limited collection space and differences in concentration of generated components. In this study, a quantitative analysis was made possible by using the low temperature concentration (cooling) trap method. Through this, it was confirmed that the correlation with the actual odor intensity was not caused by the product itself, but by the environmental factor discharged from the product after creating the odor environment.

  • This paper attempts to analyze how Paris was transformed by Haussman through comparing flaneurs in works by Balzac and Baudelaire. In both writers' works, flâneurs as the emblems of modernity observe Paris, especially architecture. Although representative of modernity, they are ambivalently obsessed with the heritage of the past. Balzac's The Wrong Side of Paris, Godefroid as a male bourgeois, is a flaneur observing antiquated architectures, the heritage of past. In Baudelaire's "The Swan for Victor Hugo" the flaneur passing through the modern Caroussel feels the Old Paris is gone. In "Parisian Dream," illusionary Paris exhibits metopolitan imagery wrought by capitalism led by Napoleon the third. The difference between the two writers demonstrate how Paris was changed by modernity.

The Effect of Curiosity and Need for Uniqueness on Emotional Responses to Art Collaborated Products including Moderating Effect of Gender (독특성 추구성향과 호기심이 아트 콜라보레이션 제품에 대한 소비자의 감정에 미치는 영향: 성별에 따른 조절효과)

  • Companies recently introduce art collaborated products incorporating culture into a product. Art collaborated products include incorporating famous movies and/or design of an artist into a newly launched product. The introduction of art collaborated products are gradually increasing. However, research for this trend is relatively scarce. Although research concerning design has discussed a number of different factors as playing a role in influencing responses to design including culture, fashion, innate preferences, etc.), only limited attention has been paid to the processes by which consumers generate responses to product designs. People with different characteristics may respond differently. When people encounter these art products, they may become curious, may think that these products are unique, novel and innovative. People tend to show different levels of curiosity when they encounter new and novel objects, which they have rarely seen or experienced. Curiosity is defined as a desire for acquiring new knowledge and new sensory experience. Previous studies demonstrated that curiosity motivates individuals to engage in exploratory behaviors. People also show different levels of need for uniqueness, which is defined as being different from others or becoming distinctive among a larger group. Individual's need for uniqueness results from signals conveyed by the material objects that individuals choose to display. Recently, researcher have developed the need for uniqueness with three distinct constructs. These three concepts include creative choice, unpopular choice, and avoidance of similarity. Creative choice is a trait tendency of an individual by expressing or differentiating himself from others through consumptions of unique products. Unpopular choice is related to an individual's tendency to consume products, which deviates from group norms. Avoidance of similarity is linked to the avoidance of consumption behavior of products that are not famous. Past research implies that people with different levels of need for uniqueness show different motivational processes. Previous research also demonstrates that different customer emotions may be derived when consumers are exposed to these art collaborated products. Research tradition has been investigated three different emotional responses such as pleasure, arousal, and dominance. Pleasure is defined as the degree to which a person feels good, joyful, happy, or satisfied in a situation. Arousal is defined as the extent to which a person feels stimulated, active, or excited. Dominance is defined as the extent that a person feels powerful vis-a-vis the environment that surrounds him/her. Previous research show that complex, speedy, and surprising stimuli may excite consumers and thus make them more pleased and engaged in their approach behavior. However, the current study identified these emotional responses as positive emotion, negative emotion, and arousal. These derived emotions may lead consumers to approach and/or avoidance behaviors. In addition, males and females tend to respond differently when they are exposed to art collaboration products. Building on this research tradition, the current study aims to investigate the inter-relationships between individual traits such as curiosity and need for uniqueness and individual's emotional responses including positive and negative emotion and arousal when people encounter various art collaborated products. Emotional responses are proposed to influence purchase intention. Additionally, previous studies show that male and females respond differently to similar stimuli. Accordingly, gender difference are proposed to moderate the links between individual traits and emotional responses. These research aims of the current study may contribute to extending our knowledge in terms of (1) which individual characteristics are related to different emotions, and (2) how these different emotional responses inter-connected to future purchase intention of arts collaborated products. In addition, (3) the different responses to these arts collaborated products by males and females will guide managers how to concoct different strategies to these segments. The questionnaire for the present study was adopted from the previous literature and validated with a pilot test. The survey was conducted in Daegu, a third largest city in South Korea, for three weeks during June and July 2011. Most respondents were in their twenties and thirties. 350 questionnaires were distributed and among them 300 were proved to be valid (valid response rate of 85.7%). Survey questionnaires from valid 300 respondents are used to test hypotheses proposed. The structural equation model (SEM) was used to validate the research model. The measurement and structural model was tested using LISREL 8.7. The measurement model test demonstrated that consistency, convergent validity, and discriminat validity of the measurement items were acceptable. The results from the structural model demonstrate that curiosity has a positive impact on positive emotion, but not on negative emotion and arousal. Need for uniqueness has three different sub-concepts such as creative choice, unpopular choice, and avoidance of similarity. The results show that creative choice has a positive effect on arousal and positive emotion, but has a negative impact on negative emotion. Unpopular choice has a positive effect on arousal, but on neither positive nor negative emotions. Avoidance of similarity has no impact on neither emotions nor arousal. The results also demonstrated that gender has a moderating influence. Males show more negative emotion to creative and unpopular choices. Implications and future research directions are discussed in conclusion.

  • Programming education helps learners solve real world problems by applying the principles of computer science. In particular, in the case of object-oriented programming centered around objects or problems that are observed in the real world, learners are able to make the most use of their programming skills in real life. Therefore, in this study, we sought ways to have learners grasp object-oriented concepts in a learner-friendly manner. To this end we conducted an experiment with six students as participants. As a result we could derive two main points. First, the learning tools which can be easily used by learners are required. Second, it is necessary to think thoroughly to learn concepts before implementation of the programming. This study has significance in the sense that it provides a learning method which helps a novice learner to learn the object-oriented programming that he or she feels difficulty to understand.

  • The subjects of this study were middle-aged women in their 40s$\sim$50s and older women aged 60 and over who were living in Seoul and Kyonggi-do, Korea. Through studying the participants' responses to the questions regarding the attributes of apparel quality in terms of the levels of satisfaction and importance, the target consumers' demand has been studied. And, they are applied to a QFD Matrix, to find out the relationship between the attributes of product quality and the guidelines of clothing design. For this study, apparel product quality is composed of five parameters: practicality, aesthetics, brand image, ease of care and fit. For the parameters of apparel product quality, the result of this study show that product improvements are needed in fit, aesthetics and practicality(in order of importance). The level of satisfaction(how satisfied consumer feels) was marked higher in brand image than that of importance(how important it is). To review demands for the apparel product attributes of formal suits for middle-aged and older women, the priority of these attributes through QFD Matrix that shows the relationship between the attributes and dress elements emphasized by designers has been examined. Material was the most important design element in designing formal suits. The shape of the pants was the second because the harmony between the jacket and the pants is important in formal suits. These were followed by trim and color tone of the jacket.
