오늘날 디지털 환경은 인간과 사회를 통찰할 수 있는 새로운 이정표를 제시하며 지식 생산 전반의 혁신을 견인하고 있다. 이에 해외 학계에서는 ‘디지털 미술사’ 분과를 출범하여 미술사 연구 과정에 디지털 기술을 본격적으로 도입하고 있으며, 이를 통해 디지털 시대에 조응하는 ‘동시대의 미술사’이자 전통 미술사 담론에 새로운 지식과 질문을 제안할 ‘미래의 미술사’로의 전환을 꾀하고 있다. 하지만 국내에서는 디지털 미술사에 대한 인식 부족 및 그 필요성과 유용성에 대한 논의가 부족한 바 본 연구에서는 디지털 미술사가 태동하게 된 계기와 국내･외 디지털 미술사의 상이한 발전 과정 속 특기할만한 차이를 규명하고자 하였다. 또한 디지털 미술사의 대표적 연구 방법론인 공학적 분석을 통한 화풍 정량화 및 이를 통한 실질적 연구 사례들을 소개함으로써 디지털 미술사의 효용 가치 및 현실적 방향성을 제시하였다. 본고의 이러한 고찰은 디지털 미술사가 국내 학계에 성공적으로 안착하기 위한 현실적 제반 상황들을 살펴보기 위함으로, 본고를 통해 ‘디지털화된’ 미술사가 아닌 ‘디지털’ 미술사로의 방향성을 정립할 수 있기를, 나아가 미술사 연구의 외연 확장을 도모할 수 있기를 바라는 바이다.

The standards for heavy metal levels in crustaceans are 0.5 mg/kg and 1.0 mg/kg or lower for lead and cadmium, respectively. Further, the contamination levels of arsenic, mercury, methyl mercury, and tin are being continuously investigated, considering their current exposure levels. Shrimps are potentially exposed to heavy metals because they inhabit areas with abundant organic matter, such as sandy or muddy shores, places with a lot of seaweed, and estuaries. This study measured the monetary value of reducing consumer anxiety and increasing consumer confidence if the government prohibits the sale of shrimp species that exceed the threshold for specific heavy metals and of the top shrimp species for which no threshold for heavy metals is specified. We derived consumer willingness-topay (WTP). Combining the estimated WTP with the number of households in the country, the total value of benefits was estimated to be 363.9 billion won. The results of this study will provide an important empirical finding, showing to what extent specific policies regarding heavy metals in seafood can alleviate consumer anxiety and provide psychological reassurance.

This study analyzed the trends of applications for patents, utility models, and designs related to leggings in order to understand the trend of development of technologies for leggings products that are continuously growing in the fashion market. In this study, trends in patent, utility model, and design applications related to leggings products filed from 2001 to 2020 with the Korean Intellectual Property Office were analyzed. As a result, first, the trends of applications for patents, utility models, and designs by year showed that the applications began to rise from 2006 and increased sharply in the 2010s. Second, applications for patents and utility models were analyzed by subject and, according to the results, the applications for compression shaping functionality were the most frequent, followed by those for construction/sewing, those for accessories and others, those for system/device, and those for multi-functionality. Third, when applications for designs were classified by target for wearing and by type of leggings, applications for general leggings designs were the most frequently filed, followed by applications for: item attachment type leggings, shapewear leggings, leggings for men, leggings for pregnant women, leggings for children, and leggings for the disabled. Although this study is limited to domestic patents, utility models, and design applications, it collected useful information related to leggings products and presented directions for future development.

PURPOSES : Since the 1990s, underground utility projects have been conducted to solve the problem of aerial communication cables. The purpose of this study is to derive optimal measures for preventing collisions with existing underground utilities and for future maintenance in the implementation of the utilities undergrounding projects. This study considered the identifier sensor and tested the optimal sensor performance for more accurate and systematic management. METHODS : In this study, three representative technologies were selected from identifier sensors generally used in air and the possibility for their use in soil and asphalt was confirmed by simulating the environment via a test construction. Three identifier sensors were selected: BLE (Bluetooth low energy) beacon, ultra-high frequency radio frequency identification (UHF RFID), and a geomagnetic recognizer. The long-term recognition performance of each identifier sensor was tested using the underground depth as a variable and the results were analyzed for comparison. RESULTS : The results of the test under limited conditions and environment demonstrated that the BLE Beacon had advantages in equipment composition, recognition range, and speed but exhibited problems with batteries in winter. The geomagnetic recognizer did not show the exact location and its influence on the surrounding environment was a disadvantage. CONCLUSIONS : Although the performance of UHF RFID has been demonstrated to be relatively suitable under these test conditions, it seems that the impact of the more diverse installation depth or medium should be reviewed for actual commercialization.

The seismic deformation method is conventionally used as a seismic design for a multi-utility tunnel in Korea. In the seismic deformation method, the soil ground’s natural period is one of the most critical factors for calculating the ground displacement using cosine functions. Correction factors for the natural period and shear wave velocity have been used to consider the non-linearity of dynamic soil properties. However, the correction factors have been issued because the correction factors have not been sufficiently studied to consider Korea’s regional conditions. This paper aims to evaluate the natural periods for the seismic deformation method considering Korea’s ground conditions. Ground response analysis was performed using seven real earthquake records on twelve sites with different soil conditions where actual multi-utility tunnels are installed. As a result, natural periods of the sites were analyzed and new correction factors were proposed according to seismic performance and Korea’s regional conditions.

This study examined the relative importance and the effective utility of fermented milk by consumers. The questionnaire was developed by an in-depth interview and literature review and was surveyed on-line. Statistical analysis was carried out descriptive analysis, ANOVA, paired t-test, and conjoint analysis using the SPSS package. First, an analysis of the consumption status of fermented milk found that the consumption frequency was 1-2 times/week (36.2%), 3-4 times/week (26.5%). The product choice attributes of fermented milk were found to be the same with ‘taste’ (3.93) and ‘manufacturing date/expired date’ (3.92), rated the highest, followed in order by, ‘sanitary quality’ (3.82), ‘origin of ingredient’ (3.81). Comparative analysis of the importance and satisfaction level of the choice attributes of fermented milk showed that the choice attributes with lower satisfaction compared to importance were ‘taste’, ‘nutrients’, ‘manufacturing data/expired date’, ‘sanitation quality’, ‘price’, ‘manufacturing method’ and ‘certification of quality’ (p<0.001, p<0.01). ‘Price’ and ‘certification of quality’ were the choice attributes of fermented milk classified as ‘Focus Here’ because of its high importance and low satisfaction. The preferred combination of relative importance in choice attributes of the fermented milk was ‘domestic resource’, ‘Eat with spoon’, and ‘none additives’. Therefore, it is believed that sales will increase if dairy companies can improve the ‘price’ and ‘certification of quality’. In addition, the use of domestic ingredients in the development of new fermented milk products in the future could be an important marketing factor in consumer choice.

우리나라를 비롯한 중국, 일본 등 여러 국가에서 기술적 사상의 창작 을 보호하는 제도로서 특허제도 이외에 특허발명보다 기술수준이 낮은 발명을 보호하기 위한 실용신안제도를 운영하고 있다. 그러나 우리나라와 일본은 실용신안제도의 이용률은 매우 저조한 반면, 중국의 경우에는 실용신안의 출원건수가 특허보다 많으며 계속 증가하고 있는 추세이다. 이와 같이 IP5 중에서 한중일의 경우 모두 실용신안제도를 운영하고는 있으나 국가별로 그 상황이 매우 다르며, 미국의 경우에는 실용신안제도를 가지고 있지 않고, 유럽의 경우 EU차원에서 통일된 실용신안제도는 없고 유럽 각국 별로 다르게 운영되고 있다. 새로운 기술을 보호하기 위한 특허제도는 국제적으로 조화 및 통일화가 추진되고 있는 상황이지만 특허제도를 보완하는 제도로 실용신안제도에 대한 국제적 논의는 도외시 되고 있는 상황이다. 특허제도를 가지고 있는 국가가 모두 실용신안법을 채택하고 있지는 않으며, 실용신안제도를 채택하고 있는 나라에서도 보호대상, 보호요건, 존속기간, 심사방법 등이 상이함에도 불구하고 실용신 안제도의 국제조화에 대한 논의는 이루어지고 있지 않으며, 국제조약에 서도 부수적인 언급만 되고 있다. 전세계 특허출원 1위를 달리고 있는 중국이 특허출원보다 출원량이 더 많은 실용신안제도를 운영하고 있는 상황과 각 국가별로 실용신안제도 채택여부와 제도의 요건(보호대상, 보 호요건, 권리행사 요건 등)이 다른 상황에서 IP의 국제조화 및 통일화에 대한 논의에서 실용신안제도를 살펴볼 필요가 있다. 이에 현재의 실용신 안제도가 TRIPs 협정, 파리조약, PCT 등 IP 분야 대표적인 국제조약에 있어서 해당 조약체결의 취지 등을 고려할 때, 국제규범과의 정합성 등을 검토해 볼 필요가 있다.

목적：본 연구에서는 간세포암 환자들을 대상으로 직접 얻은 2000 s/㎟의 높은 b-value의 확산강조영상(diffusion weighted image, DWI)과 낮은 b-value들을 외삽(外揷, extrapolation) 하여 재구성한 2000 s/㎟의 같은 b-value의 확산강조영상 (computed diffusion weighted image, cDWI)을 비교하여 cDWI의 유용성을 평가해보고자 한다. 대상 및 방법：총 30명의 간세포암(hepatocellular carcinoma, HCC) 환자를 대상으로 실험하였다. b-value 0, 50, 800, 2000 s/㎟을 이용한 DWI를 획득하고, b-value 0, 50, 800 s/㎟의 DWI만을 외삽하여 b-value 2000 s/㎟의 cDWI를 재구성하였다. 직접 얻은 b-value 2000 s/㎟의 DWI와 재구성으로 얻은 b-value 2000 s/㎟의 cDWI의 신호 대 잡음비 (Signal-to-noise ratio, SNR), 대조도 대 잡음비(Contrast-to-noise ratio, CNR)를 정량평가하였다. 또한 자기공명영상(magnetic resonance imaging, MRI) 검사 경력이 서로 다른 방사선사 2 명이 각각 시각적인 영상의 질에 대해 정성평가를 하였다. 정량평가는 대응표본 t-검정을 통해 통계적 유의성을 검정하였다. 정성평가는 대응표본 t-검정과 함께, 각 평가자 간 평가 점수의 일치도 분석을 위해 급내상관계수(Intraclass correlation coefficient, ICC)를 실시하였다. 결과：정량평가 결과는 DWI의 SNR이 각각 간실질에서 40.68±1.94, HCC에서 90.8±6.12, 문맥에서 62.69±5.08이었다. cDWI의 SNR은 각각 간실질에서 38.36±4.55, HCC에서 100.52±9.33, 문맥에서 3.6±0.43이었다. DWI의 CNR은 각각 간실질과 HCC 사이에서 48.31±5.72, 간 실질과 문맥 사이에서 22.01±3.2, HCC와 문맥 사이에서 49.71±5.14이었다. cDWI의 CNR은 각각 간실질과 HCC 사이에서 57.66±6.16, 간 실질과 문맥 사이에서 34.76±4.18, HCC와 문맥 사이에서 96.2±8.87이었다. 정성평가 결과, 방사선사1이 DWI를 1.14±0.36, cDWI을 3.36±0.49로 평가하였다. 방사선 사2는 DWI를 1.18±0.39, cDWI를 3.43±0.5로 평가하였다. 정량평가와 정성평가 모두에서 대응표본 t-검정은 통계적 유의성을 나타냈다(p<0.05). 정성평가에서 급내상관계수는 DWI에서 0.932 (95% CI 0.852-0.968, p=0.000), cDWI에서 0.925 (95% CI 0.838-0.965, p=0.000)으로 매우 높은 일치도를 보였다. 결론：병소 외의 간의 구조물에서는 고식적인 b-value 2000 s/㎟의 DWI의 SNR이 높았다. 하지만 간세포암의 SNR과 모든 경우의 CNR, 시각적 평가는 b-value 2000 s/㎟의 cDWI에서 더 높았다. 특히 혈관 등 구조물들의 경계에서 cDWI의 구별 능력이 뛰어났다. 따라서 2000 s/㎟의 높은 b-value의 cDWI은 기존의 DWI 방식을 대체하여, 간에서 구조물 간에 더 나은 분해능을 제공하고, 검사시간 단축을 실현할 수 있다.

The goal of this study was to identify how well learners express themselves when an online conversation environment is provided in a SW education curriculum. In order to achieve this goal, this study took place during the first semester of 2018, with the subjects being 115 students belonging to two classes from 5th grade and two from the 2nd year of middle school in schools that were conducting the SW leadership school project. The results of creating an online conversation environment and collecting the students’ opinions about it showed that the higher the age of the students, the better they adapted to the online environment and, furthermore, female students especially proved to be more active at online expressions compared to male students.

Promalactis established by Meyrick in 1908, is one of the highest species richness genera of the family Oecophoridae. Over 240 described species are mainly distributed from Oriental and Palaearctic regions. They are usually a tiny-sized and exhibit subtle morphological differences which make problems on morphological-based identification. In this study, we performed DNA barcoding study for the Promalactis by using mitochondrial cytochrome c oxidase subunit I (COI). From analyzing 155 COI sequences, we observed the usefulness of the COI in species identification with intraspecific genetic variation (range 0.0-2.1%) and interspecific genetic divergence (range 2.8-15.4%).

Purpose – This paper holds a purpose to examine the influence of perceived utility, contextual relevance and lifestyle on the acceptance of mobile advertising among millennials in Indonesia (specifically in Bandung). The three factors represent an extension of the general model of mobile advertising which is largely influenced by the Theory of Reasoned Action (TRA). The factors are proposed to extend the model to include factors at individual (receiver), object (message) and contextual levels. Lifestyle, Perceived Utility, and Contextual Relevance are factors at individual, object and context that are posited to influence the acceptance of mobile advertising in this study. Specifically, the current study is aimed at elaborating the role of those factors in influencing the acceptance of mobile advertising among millennials in Bandung, Indonesia. Relevant theories – mobile marketing definition and scope from various literature, Theory of Reasoned Action (TRA), theory of perceived utility, consumers’ utilization of contextual information in mobile advertising, and the influence of lifestyle – as representation of individual factor – on mobile advertising acceptance are the most relevant theories for the current paper. Design/methodology/approach – The research was conducted by devising a new model that includes acceptance of mobile advertising, attitude toward mobile advertising, subjective norm in relation to mobile advertising, perceived utility of mobile advertising, contextual relevance of message and income (as representation of individual lifestyle). The questionnaires distributed to young adults segment within varsity area. The data is then examined and evaluated through structural equation modelling (SEM) which requires analysis on measurement and path model. Findings – The study resulted in several findings, mostly confirming proposed hypotheses in varying degrees. The results conclude that attitude is of great importance in the acceptance of mobile advertising. Subjective norms and contextual relevance are positively related to attitudes — which lead to acceptance, while both perceived utility and income in negative relations to attitude and acceptance consecutively. Research implications and limitations – This study adds up to the growing amount of related research in various countries. Companies making use of the mobile advertising as part of their promotional strategies should always think of the manner and matter by which the advertisements arrive while serving as benefit for marketers and consumers. A good mobile advertising strategy will put more effort into giving useful information that is appropriate to the context and consumer segments it targeted. This research is conducted on respondents from Indonesian consumers, specifically in the area of Bandung, which may not represent the other segments of users of mobile advertising. In addition, the case covers a convenience sample of consumers that may again impact the representativeness of the research findings. Originality/value – This study provides findings on the effects of contingency factors that have been missing in the previous research on the acceptance of mobile advertising. Paper type – Applied research

The present research examines the Uncertainty-Prediction Asymmetry (UPA) hypothesis, that low certainty incidental emotions, compared to their high certainty counterparts, lead to utility overprediction and to lower forecasting error. Introduction Cognitive appraisals of emotion have been included in the state-of-the-art theory of emotion and decision-making (Lerner & Keltner, 2000; Lerner, Li, Valdesolo, & Kassam, 2015). For instance, Tiedens & Linton (2001) discuss how happiness involves appraisals of high certainty, and sadness involves appraisals of low certainty. In terms of forecasting, systematic processing is generally considered to lead to less forecasting error compared to heuristic processing. Tiedens & Linton (2001) argue that, if accuracy is the ultimate goal the individual needs to rely on more thoughtful processes. Seeking a state of certainty is more cognitively engaging and requires more cognitive resources. But how do people predict future utilities in the first place? Theoretical background Kahneman & Thaler (2006) analyze forecasting as a two-step procedure, encompassing a current prediction as well as a future event. Breaking down the present and future situation allows researchers to assess accuracy and detect how errors occur. Kahneman & Snell (1992) report that people tend to underpredict future utilities. Typically, the experienced utility is higher (i.e. more liked or less disliked) compared to the earlier prediction. In the present paper we argue that emotional uncertainty leads to utility overprediction and thus reduces forecasting error. This hypothesis is in line with the Appraisal-Tendency Framework (ATF-overview in Lerner et al., 2015). According to the ATF, an emotion may trigger a cognitive predisposition to assess future events in line with the central appraisal dimensions that triggered that emotion. Such appraisals provide a perceptual schema for interpreting subsequent situations. In the context of the present research, the certainty-uncertainty cognitive appraisal is hypothesized to trigger a predisposition that affects the utility prediction mechanism and leads to utility overprediction. This hypothesis is also in line with the uncertainty intensification hypothesis (Bar-Anan, Wilson, & Gilbert, 2009), according to which the uncertainty of experienced emotions makes unpleasant events more unpleasant and pleasant events more pleasant. The present research examines an Uncertainty-Prediction Asymmetry (UPA) hypothesis. In three experimental studies we test the hypotheses that low certainty incidental emotions, compared to their high certainty counterparts, lead to utility overprediction (H1) and to lower forecasting error (H2). Emotional certainty, as an appraisal dimension of emotions, is expected to create a prediction asymmetry through its effect on both predicted utility and forecasting error. The mediating role of heuristic processing in the relationship between emotional certainty and forecasting error is also investigated. Experiment 1 The first experiment examines the hypothesis that low emotional certainty leads to utility overprediction (H1). Eighty postgraduate students were randomly assigned to a high emotional certainty (disgust) vs. a low emotional certainty (fear) condition. Emotion induction involved exposure to pretested video clips (see Han et al., 2012). Following this manipulation, the experimental utility (a small candy bar) was distributed and participants were encouraged to consume it (see Kahneman & Snell, 1992). They were then asked to report on 13-point scales how much they liked the utility and to predict how much they would like it in the future consumption occasion (a week later). The results revealed a significant difference in predicted utility between the high (M = 2.22, SD = 1.33) and low (M =3.65, SD = 1.37) emotional certainty conditions (F = 4.43, p = 0.04, partial eta squared = 0.10). Experiment 2 The second experiment includes a “future event”, that is measures of the utility that was originally predicted, in order to also estimate forecasting error. The experiment therefore tests if (a) the main effect of emotional uncertainty on predicted utility is confirmed (H1) and (b) there is a significant main effect of emotional uncertainty on forecasting error (H2). In addition, this experiment examines whether these effects are independent of the valence appraisal dimension of emotions. Given that Experiment 1 involved two negatively valenced emotions, emotional valence (positive vs. negative) was included in the experimental design. Seventy three postgraduate students participated in a five-consecutive-days experiment. During the first day, participants were randomly assigned to a fear (negative valence, low certainty), disgust (negative valence, high certainty), hope (positive valence, low certainty) or happiness (positive valence, high certainty) condition. Specifically, participants were asked to report an experience in which they had felt this particular emotion through an Autobiographical Emotional Memory Task (AEMT) (as in Smith & Ellsworth, 1985). Following this experimental manipulation, the experimental utility (a small chocolate bar) was distributed and they were again encouraged to consume. Subsequently, they were asked to rate how much they liked and how much they would like the utility on the fifth day. Depth of processing was assessed with four items (α=0.77), adjusted from Griffin et al. (2002). Specifically, these items measured the heuristic processing performed during the prediction process. Participants were contacted again on each of the remaining four days and were asked to consume the utility and to complete a short questionnaire (comprising ratings of the consumption experience and of the predicted utility on the fifth day). The results reported here involve only the data obtained on the first and final day of the experiment, and the forecasting error was estimated as the difference between the experienced utility of the last day and the predicted utility of the first day. In line with hypothesis H1, emotional certainty had a significant main effect on predicted utility (F = 6.18, p = 0.002, partial eta squared = 0.08). Specifically, predicted utility in the low emotional certainty condition was higher (M = 2.69, SD = 1.09), compared to that of the high certainty condition (M = 0.78, SD = 1.66). There was no significant interaction effect between certainty and valence. These findings provide further support for our H1 and indicate that emotional certainty influences utility prediction irrespective of the valence of incidental emotions. Moreover, a significant main effect of certainty on forecasting error was observed (F = 4.16, p = 0.045, partial eta squared = 0.06). Forecasting error was lower in the low certainty condition (M = 0.59, SD = 1.28) compared to the high certainty condition (M = 2.19, SD = 1.48). There was no significant interaction effect. Moreover, a mediation analysis revealed that heuristic processing mediated the effect of certainty on forecasting error (p**<0.05). Experiment 3 The previous two experiments indicate that the effects of incidental emotional states on predicted utility and forecasting error may be due to the certainty-appraisal dimension of these emotional states. A possible criticism and an inherent limitation of Experiments 1 and 2 might lie on the possibility that these effects are not independent of the other appraisal dimensions. This is related to a key methodological issue. In Experiments 1 and 2, the induced emotions were different in terms of certainty or uncertainty, but these emotions might have differed in other ways and across other appraisal dimensions as well. To eliminate this possibility and to strengthen our argument, we employ here a manipulation of the certainty appraisal of the same emotion. We therefore compare predicted utility and forecasting error in the same emotional state under conditions of low and high certainty. In Experiments 1 and 2 the emotions induced are strong representatives of each side of the certainty appraisal dimension. However, emotions located in the middle of this dimension provide an interesting opportunity since they might allow us to compare their effects when they are associated with lower or higher levels of certainty. In this experiment we have chosen to focus on the emotional state of sadness. Sadness was selected because it is near the middle of the certainty-uncertainty dimension (Smith & Ellsworth, 1985). Similar manipulations of sadness have been reported in the literature (Tiedens & Linton, 2001). Sixty postgraduate students were randomly assigned to a low vs. high certainty sadness condition. High certainty participants were asked to recall and report an experience or event in which they had felt high certainty sadness (i.e. during which they understood what was happening and could predict what was going to happen next), through an Autobiographical Emotional Memory Task (AEMT) as in Experiment 2. Similarly, low certainty participants were asked to recall and report an event or experience that had generated low certainty sadness. Following the experimental manipulation, the experimental utility (a small chocolate bar) was served. Participants were again encouraged to consume some of it and were asked to complete 13-point ratings of how much they liked it and how much they would like it in the future occasion (a week later). Eight items (α=0.81), adapted from Griffin et al. (2002), measured the heuristic processing performed during the prediction process. Participants also completed ten items adjusted from PANAS questionnaire (Watson et al., 1988). A week later, participants consumed the utility and completed a short questionnaire. The results revealed a significant main effect of certainty on the predicted utility (F = 4.00, p = 0.05, partial eta squared = 0.06). Predicted utility in the low certainty sadness condition was higher (M = 4.21, SD = 1.55) compared to that of the high certainty condition (M = 3.35, SD = 1.78). A significant main effect of certainty on forecasting error was also observed (F = 5.04, p = 0.03, partial eta squared = 0.10). Forecasting error in the low certainty condition (M = -0.10, SD = 1.65) was lower compared to that of the high certainty condition (M = 1.02, SD = 1.81). A mediation analysis revealed that heuristic processing again mediated the effect of certainty on forecasting error (p**<0.05). Conclusion The contribution of this research is mostly highlighted by the counter-intuitive findings that lower certainty emotions lead to judgment with higher accuracy, as well as to an overprediction of utilities, related to their certainty counterparts. Therefore, the current findings provide support for the proposed Uncertainty-Prediction dual Asymmetry (UPA) hypothesis. Future research needs to corroborate these findings, to clarify the mechanisms underlying the observed asymmetry and to identify boundary conditions.

People want to watch a sports game which cannot anticipate the result until the end of the game. Sometimes, however, excessive tension of contest lowers the interest of audience. Vast amount of existing researches have focused on finding explanation about what makes a difference of the preference level of suspense among sports fans and where is the optimal level of suspense. We apply Expected Utility Theory and Prospect theory to illustrate the expected utility of sports spectators. According to our findings, if someone someone who is satisfied more when the cheering team wins, he or she may prefer lopsided match than close match. And fans who support winning team, which means team which wins often, prefer lopsided match to close match because they forecast their team will win more than fans who support losing team, which means team which loses often. We manipulate the level of satisfaction when the cheering team wins (S) and subjective forecasted probability of win before the game (Q) of respondents and measure the utility of them toward difference game aspect (P) to verify our hypothesis. This study was carried out to investigate how the satisfaction of sports spectators will change according to the change of the game aspect. In particular, research model was set up using the Expected Utility Theory and Prospect Theory of economics. The use of economics models to explain sports consumer behavior is different from that of previous studies, and consumers' prior expectations can affect the current game viewing based on Prospect Theory is another contribution of this research.
