The global society is overwhelmed by growing social inequality and environmental pollution. Especially, the fashion industry has been linked to hazardous clothing wastes and exploitation of labor in poor countries. We acknowledge that the sustainability philosophy could be an alternative governing principle that can lead us to a better future for the fashion industry. This study investigates brain responses of fashion professionals and consumers as they are presented with sustainable fashion of luxury and SPA brands. Using functional magnetic resonance imaging (fMRI), the whole brain responses of participants were measured and analyzed to reveal how their brain responses differ depending on fashion products’ brand type and certification mark. We build an online education platform for professionals and lay consumers on the subject of sustainable fashion. Brain responses are measured from both groups of professionals and consumers while they are exposed to sustainable fashion products of luxury and SPA brands. A group of subjects watch the online educational program while under the counterpart condition subjects see another video of the same length, unrelated to sustainability. BOLD measures are acquired using Siemens 3T scanner and analyzed using SPM 12 software. We find selective brain activation patterns that can distinguish the educated group from the uneducated ones. The practical implication of this study is that we must do our best to build a sustainability education program which can motivate professionals and consumers effectively, by stimulating both cognitive and affective bases of behavioral change.

Unlike older generation whose consumption of music was bounded by their local culture, today’s young consumers access music beyond cultural boundaries. Many successful pop music in cyber space attracted billions of listeners from all over the world. The young generation born and raised in the digital age, are often thought to have altered sensory-neural characteristics because of their extensive use of electronic device since early childhood. This study investigates a perceptual saturation hypothesis which posits that in order to capture the young generation’s hard-to-get attention, online music must present a high level of energy and rhythm that is near the point of perceptual saturation. We conducted a functional near-infrared spectroscopy (fNIRS) experiment with sixty-four young adults and found that total cerebral blood volume over prefrontal brain area was higher for a song that presents acoustic intensity near the point of perceptual saturation than a counterpart stimulus with lower levels of acoustic intensity. The degrees of prefrontal hemodynamic randomness decreased significantly while the participants listened to YouTube music that provided high levels of acoustic stimulation. Online popularity, recorded as the number of daily hits, was positively correlated with the total cerebral blood volume and negatively correlated with hemodynamic randomness.

The purpose of this study was to investigate the relationship between frequency of coffee consumption, metabolic biomarkers, and nutrition intake in adult participants in the combined 2007~2009 Korean National Health and Nutrition Examination Survey (KNHANES). Subjects (2,095 males and 3,297 females) were classified according to sex and frequency of coffee consumption (≤1 time/month, ≥2 times/month and ≤6 times/week, 1 time/day, 2 times/day, 3 times/day) using food frequency questionnaires. Nutrition intake was analyzed using 24 h recall data. The 3 times/day coffee consumption group had a significantly higher age, and frequency of smokers and drinkers compared to the ≤1 time/month coffee consumption group in both male and female participants. Males in the 3 times/day coffee consumption group had a significantly lower HDL-cholesterol level, but females had a higher waist circumference compared with the ≤1 time/month coffee consumption group. Males in the 3 times/day coffee consumption group had a significantly lower nutrient density of fiber, vitamin B2, vitamin C, calcium and phosphorus compared with the ≤1 time/month coffee intake group. Females in the 3 times/day coffee consumption group had a significantly higher nutrient density of fat and niacin, but lower nutrient density of carbohydrate, calcium, phosphorus, and iron compared with the ≤1 time/month coffee intake group. In males, the frequency of coffee consumption was not associated with the levels of metabolic biomarkers. In females, the frequency of coffee consumption was positively associated with diastolic blood pressure after adjustments for multiple confounding factors, including age, BMI, smoking status, alcohol consumption, physical activity and energy intake. Coffee consumption was associated with decreased diastolic blood pressure in females. These findings suggest the importance of an awareness of the association between coffee consumption and metabolic risk.

The recent developments of artificial intelligence (AI), such as Google AlphaGo and IBM’s Watson, defeating human experts in public game venues, have instigated much surprise and awe among us. We are now genuinely curious about the true growth potential of AI into the future. Some of us are already imagining a darkening future where all human managerial positions can be replaced by machines leaving humans in a marginalized place after the point of singularity where machine intelligence achieves intellectual superiority over us and becomes a truly autonomous being. Likewise, the potential of AI has been overestimated or underestimated; rarely has it been addressed in the open context where marketing academics serve the role of an architect of future marketing AI, to provide valuable insights. We are enlightened about a possibility that the future of and marketing can greatly benefit from advanced forms of artificial intelligence. But how and where can this new technology be integrated in the every-day lives of consumers, to optimize business functions and create much higher levels of collective value for consumers, companies, and machines altogether? In this talk, we will discuss the following three points related to the AI and its potential future in the field of marketing. First, for consumers, we will discuss how marketing AI can help consumers to make better decisions about their eating, health, and consumption to enjoy better life, do more, and be happy. Second, for business, we will discuss the roles of AI and design a collaborative work process that can employ both human ingenuity and machine accuracy. Third, we suggest ethical issues related to marketing AI, delineating its boundaries and suggest governing policies to prevent potential danger spots. The purpose of talk is not to present a definitive answer, but to instigate an open discussion among the marketing academics, about the future of marketing, where AI will be an indispensable partner in the value creation process.

초등교사와 영양교사는 어린이 식생활 교육자로서 이들의 식품안전 및 위해에 대한 인식은 식생활교육에 큰 영향을 미칠 수 있다. 따라서 본 연구에서는 주요 식품 위해 요인으로 오인되고 있는 식품첨가물에 대해 수도권 소재초등학교에 근무하는 초등교사(279명)와 영양교사(72명)를 대상으로 식품첨가물에 대한 인식 및 정보요구도에 대한 설문조사를 실시하여 분석함으로써, 식품첨가물에 대한 올바른 정보전달 촉진을 위한 기초자료를 확보하고자 하였다. 맛을 우선하는 교사(39.1%)에 비해 영양교사는 식품을 구입할 때 안전성(68.1%)을 가장 먼저 고려하여 유의한차이(p < 0.001)를 보였고, 제조사, 가격 유통기한 외에 교사는 원산지(32.5%), 영양교사는 주성분(50.0%)을 우선 확인한다고 하였다(p < 0.01). 식품표시 이해도는, 주성분, 식품첨가물, 영양성분, 인증마크 등 모든 부분에서 영양교사가 높았으며, 교사(3.53), 영양교사(4.17) 모두 식품첨가물관련 표시 이해도가 가장 낮게 나타났다. 교사, 영양교사 모두 식품의 안전을 위협하는 요인으로 환경오염물질, 식중독 세균과 바이러스, 식품첨가물 순서로 응답하였고, 가공식품 구매시 ‘무첨가’, ‘무색소’ 표시가 있는 식품을 구매한다는 응답 비율이 높았다. 또한 영양교사는 식품첨가 물이 안전성, 유효성 평가를 거치고(100%), 사용기준 및 규격이 정해져 있다(81.9%)는 것을 안다고 응답했음에도 불구하고, 교사(75.2%)보다 많은 87.5%가 식품첨가물 섭취는 건강에 위험하다고 응답하는 괴리를 보여 이들에 대한 올바른 정보전달의 필요성을 확인할 수 있었다. 교사 및 영양교사 모두 식품첨가물에 대해 가장 알고싶어 하는 정보는 ‘안전성과 위험성’이었고, 정보매체로는 교사는 TV(3.80)를, 영양교사는 강의(3.65)를 가장 선호하였다. 식품첨가물에 대한 정보 제공기관이나 제공자에 대한 신뢰도에서 정부기관이나 식약처 공무원에 대한 신뢰도는 병원, 대학연구기관, 의사, 연구원 등에 대한 신뢰도보다 낮았다. 대중매체의 정보는 신뢰하지 않는다는 비율이 높았으나, 대중매체를 접한 후 교사(39.4%)는 식품첨가물 표시를 보게 된다고 하였고, 영양교사(50%)는 식품첨가물이 함유된 식품을 줄인다고 응답하여 그 영향력을 확인할 수 있었다. 또한 대중매체 내용이 선정적·감성적 접근을 하여 문제가 있다고 답변하며, 정부가 잘못된 정보를 곧바로 바로잡을 수 있도록 전문가 집단을 활용하여 균형적으로 정보를 제공하여야 한다고 지적하였다. 본 연구 결과, 초등교사와 영양교사는 식품첨가물에 대해 각기 다른 인식과 정보요구도를 보이고 있어 어린이들에게 올바른 식생활교육을 할 수 있도록 식품첨가물에 대한 정보전달 노력이 요구된다.

This study was conducted to investigate the effectiveness of a nutrition and exercise education program on weight control and nutrition knowledge. The nutrition-exercise educational period was 12 weeks. The subjects were 160 adult women with an average age of 48.1 years. We investigated general characteristics, diet history, eating habits, and intake frequencies of six food groups by survey. A total of 94 women among the subjects participated in the pre and post nutrition knowledge evaluations and anthropometric data assessment. After the program, body weight, body mass index (BMI), and waist circumference significantly decreased. Further, % of body fat decreased, but not significantly. BMI significantly decreased (p<0.001) from 25.14 to 24.80 kg/m2, and waist circumference significantly decreased (p<0.001) from 79.72 to 77.63 cm. The nutrition knowledge scores of subjects significantly increased (p<0.001) from 8.01 to 9.03. However, there was little change in employment. These results suggest that the nutrition-exercise education program may improve obesity index and nutrition knowledge. However, it is necessary to develop a specialized weight control program for workers.

A choice in temporal discounting is often made on one preferred option between a sooner but smaller reward and a later but larger reward. In temporal discounting, a consumer undergoes an evaluation process concerning the trade-offs between time delay (i.e., a choice between sooner and later receipts) and the amount of reward (i.e., a choice between smaller and larger rewards). It has been evidenced that a surprisingly large number of consumers is inclined to choose a sooner option with a lower economic value. Those consumers tend to apply an excessive temporal discounting rate to the time delay and as a result, the sooner option with lower economic value stands out to be more attractive. However, there is another group of consumers who deliberately promote the long-term perspective in the evaluation process. Those consumers show a high tendency of choosing a later option with greater economic value. A key factor affecting the evaluation process is the sensitivity to time delay a consumer entails. The sensitivity to time delay could systematically affect the representations of hedonic pleasure being projected at different time delays and is the basis of individual differences in hedonic orientation. An anhedonia, a person with the ability to control physical pleasure, is likely to be less sensitive to time delay and apply a lower discounting rate for delayed rewards because he processes the presently available pleasure less intensively than do ordinary consumers. Thus, anhedonic consumers are more likely to choose a delay reward in temporal discounting choices. In a famous fable by Aesop, “The Ant and the Grasshopper” suggest a possible linkage between hedonic orientation and temporal discounting tendency. The story goes that the Grasshopper enjoys whatever is on its hands and does not give much thought to what is going to happen in the future, while the Ant takes on the hardship denying the current pleasure as he plans for the difficult winter time. We conducted an experiment to investigate the relationships among individual differences in hedonic orientation, and the behavioral choices in temporal discounting trials by examining the EEG theta (4-8 Hz) correlates. A hedonic orientation questionnaire was developed using twenty selected items from Physical Anhedonia Scale, Barratt Impulsiveness Scale and Impulsive Buying Scale. Using the questionnaire, the hedonic orientation of fifteen participants was analyzed. Among them, five participants were classified into anhedonia (Ant-like, AN) group and ten participants were into hedonic pleasure dependent (Grasshopper-like, GH) group. Participants conducted ten temporal discounting trials and, in each trial, a choice was made between two options, either a smaller reward today (the “now” option) or a greater reward to be received after a specified time delay (the “future-oriented” option). The absolute theta activations while viewing a future-oriented option in each trial were analyzed as the neural correlates of temporal discounting. The results indicated that the hedonic orientation of participants had a high prediction power of not only behavioral choices in temporal discounting but also EEG theta activations in the frontal brain region. In analyzing temporal discounting tendencies, the discounting rate of AN group was found to be lower than that of GH group. In addition, EEG theta analysis shows two interesting activation patterns in the frontal region. First, AN group showed higher frontal theta activations than GH group indicating its deliberate engagement to future-oriented options. Second, theta activations in the Dorsolateral Prefrontal Cortex (DLPFC), more specifically AF3 and AFz, were negatively correlated with the discounting rate of participants. Neuroscience researches often refer that DLPFC is associated with deliberate and analytic information processing. Therefore, the high theta activations in DLPFC could be considered as a distinctive neural indicator of high anhedonia traits and low temporal impulsivity.

The aim of the present research is to explore the neural features of intertemporal choice. Intertemporal choice concerns the phenomenon of temporal discounting which demonstrates consumers’ tendency to devalue a future reward as the receipt of money reward is delayed further distantly into the future. It is also called the ‘present bias,’ a special kind of attachment consumers place to immediate a cash reward which consumers are willing to take even at a discount, instead of saving it for the future. The urge to choose an immediate reward at some discounting rates, i.e., temporal impulsivity, is deeply embedded in our instinct. On the other hand, the choice for a delayed option is made as a result of effortful and deliberate cognitive control, by suppressing the urge for instant gratification and shifting focus to the long-term gain. Neuroscience researchers have found the prefrontal cortex as a key brain region behind deliberate and analytic decision-making such as reward delay. The experimental paradigm used in this study adopted from Kirby, Petry, & Bickel (1999). There were ten intertemporal investment choices representing six different levels of discounting rates. Participants (N=21) were given the two investment options, as “take it now” and a “save for later” options, and they were asked to indicate a preferred option. The brain waves were recorded using a 32 channel EEG system. We conducted noise control by using Independent Component Analysis (ICA) in EEGLAB and analyzed the Event-Related Potentials (ERP) particularly focusing on the phase when each participant was examining the future-oriented “save for later” option. The behavioral responses were divided into two groups, one in which the present option was selected and the other in which a future-oriented “save it for later” option was selected. Custom-written Matlab codes were used to compare the differences in ERPs between the two choice responses. A greater positive component of P3 after 300 milliseconds at the onset of the future option was observed in the fronto-parietal regions when the “save it for later” options were chosen compared to when the “take it now” choices were made. Hence, during intertemporal choice, the fronto-parietal regions are likely to play a key role in enabling the long-term perspective and consequently, precipitate the choice of a future-oriented deal. The P3 signal across the fronto-parietal regions may potentially be a proximal indicator of a future-oriented choice during intertemporal financial decision-making.

This study was conducted to evaluate the quality characteristics and antioxidant activities of rice flour sponge cakes containing 0, 20, 30, 40, and 50% Helianthus tuberosus powder (HTP). As HTP content of sponge cake increased, the pH of sponge cake batter significantly decreased, whereas specific gravity significantly increased (p<0.05). Meanwhile, volume and symmetry indices of sponge cake were inversely proportional to HTP amount. Further, with higher HTP content in sponge cake, L and b values of crumbs significantly decreased (p<0.05), whereas a value significantly increased (p<0.05). L, a, and b values of crust significantly increased with higher HTP content. For texture characteristics, hardness, cohesiveness, gumminess, and chewiness of sponge cake significantly increased (p<0.05),whereas cohesiveness did not significantly change. In the sensory evaluation test, rice sponge cake prepared with 10% HTP showed the highest sensory scores in terms of color, flavor, taste, softness properties, and overall preference. The levels of total polyphenol compounds and DPPH radical scavenging activities of rice sponge cakes significantly increased with higher HTP contents (p<0.05). The results of this study suggest that rice sponge cake containing 10% HTP is the most appropriate for quality characteristics and sensory evaluation. This study also provides a way to increase the quality, texture characteristics, and organoleptic properties of sponge cake while reducing HTP content to less than 10% in order to satisfy consumer tastes.

Matrix metalloproteinases (MMPs) have been implicated in tissue development and re-modeling. Dynamic morphological changes of tooth germs reflect involvement of these enzymes during odontogenesis. The present study was performed to investigate expression and localization of MMP-2 and MMP-9, which have been known to have type IV collagenase activities, in rat tooth germs at different developmental stages. MMP-2 expression was increased gradually in the tooth germs from cap to crown staged germs at both transcription and translation levels. The localization of this molecule was detected in secretory ameloblasts and preameloblasts. The strong immunoreactivities were occasionally seen along the basement membrane between ameloblasts (or preameloblasts) and odontoblasts (preodontoblasts). However, weak reactivity was detected in odontoblasts and reduced enamel epithelium. The level of MMP-9 expression in the tooth germs was higher in cap stage than in crown staged germs at both transcription and translation levels. They were strongly expressed in both ameloblasts and odontoblasts. Even though reduced enamel epithelium after enamel formation and inner enamel epithelium at the cap stage exhibited weak reactivity, strong reactivity was detected in dental follicles and perifollicular tissues surrounding cap staged germs. These results suggested that MMP-2 may involve degradation of the basement membrane during hard tissue formation, whereas MMP-9 might be involved in remodeling of follicular tissues.

This study was conducted to investigate the change in the anthropometric values, biochemical index, nutritional knowledge, food habits and nutrient intakes in obese children after a weight control program. The subjects of the study were 22 obese children with an obesity index over 120%. The children that participated in this study took nutritional education for weight control along with exercise once a week. The weight control program was conducted for 10 weeks. The BMI, WHR (Waist-Hip ratio), body fat (%) significantly decreased at the end of the weight control program. Total cholesterol and LDL cholesterol were also significantly decreased. The nutritional knowledge scores and knowledge score about obesity were slightly improved. Energy intake significantly decreased from 1768 to 1421 kcal. Intake of Ca, Na, K, vitamin A, vitamin B6, vitamin C and folate increased, while intakes of P, Zn, vitamin B1, vitamin B2, vitamin E and niacin decreased. The distribution of energy intake was significantly changed for the better. The percent fat consumed decreased from 26.5 to 19.7%. In addition, the distribution of energy intake in the meals was changed, where the percent calories consumed during lunch significantly increased from 31.4 to 40.1% and the calorie percentage consumed from snacks significantly decreased from 17.6 to 10.7%. In conclusion, the nutritional education in the weight control program, which was conducted for 10 weeks, was effective in improving the anthropometric values, biochemical index and nutrient intake although nutrition knowledge and eating behaviors only changed slightly. Thus, nutritional weight control programs for obese children should be continuously provided under the proper cooperation of a nutritional teacher at elementary schools.

To develop molecular markers for late flowering time in radish we performed QTL-seq analysis in which whole genomes are sequenced and SNPs between two groups showing opposite phenotypes in F2 population are analyzed to find regions or QTLs involved in a trait of interest. Two inbred lines (NH-JS1 and NH-JS2) showing opposite phenotypes of flowering time were selected to generate F2 population for the analysis. NH-JS1 showed late flowering time whereas NH-JS2 early flowering time. Genomic DNA from the two lines were extracted and sequenced. In addition F2 population from F1 between NH-JS1 and NH-JS2 was generated and flowering time phenotypes of 180 F2 plants were analyzed. We selected 11 plants with late flowering time and 12 plants showing early flowering time. We extracted DNA from each individuals from the two groups and bulked them to generate two bulked DNA samples that are subject to whole genome resequencing. Preliminary analysis of SNP data from the resequencing showed that there may be several QTLs involved in flowering time control in radish.

When relations improve between North and South Korea, there will be demand for North Korean edible plants because of the low labor cost and similar environmental conditions. However, there is no reliable information about trace elements, metals, and metalloids in edible plants from North Korea. Selenium (Se) and germanium (Ge) have positive effects on basic human health and are therapeutical in diverse illnesses. Metal and metalloid (Cd, Pb) poisoning, on the other hand, can cause many health problems. Plants collected from North Korea had higher selenium content than those from South Korea. Although none of the collected species exceeded the permissible levels of cadmium and lead, their content in plants was significantly higher in North Korea than in South Korea. The high metal contents in plants collected from North Korea may be associated with the soil physicochemical properties as well as the accumulated amounts of elements in the soil.

In this study, 0, 20, 40, 60, 80, and 100% Ulmus pumila L. nonglutinous and glutinous sikhe were added to Ulmus pumila L. extracts for 15 days at 4℃, and for seven days at 25℃, to examine the extracts' storage properties and sensory characteristics. The results are as follows: (1) On the changes of pH and acidity during storage of Ulmus pumila L. nonglutinous and glutinous sikhe, both of them showed lower pH values with lower additive Ulmus pumila L. extract contents. The pH value continuously decreased with a longer storage period, and the acidity was higher with a lower concentration of Ulmus pumila L. extract. (2) The total microbial cell count during storage of Ulmus pumila L. nonglutinous and glutinous sikhe at 4℃ was 4.6-5.0 log CFU/g at 0 day. The sikhe to which Ulmus pumila L. extract was not added increased to 8.8-9.0 log CFU/g on the seventh storage day, while the sikhye to which 80 and 100% Ulmus pumila L. extracts were added were 7.8 and 6.9 logCFU/g, respectively. Thus, the total cell count was lower with a higher additive content of Ulmus pumila L. extract. The total cell count of the sikhe to which 0-60% Ulmus pumila L. extracts reached the maximum value on the seventh storage day and did not show any change thereafter. The total cell count of the sikhe to which 80 and 100% Ulmus pumila L. extracts were added, however, reached the maximum value on the 10th to 13th storage days, thus showing that the storage period was increased by Ulmus pumila L. At 25℃, the total cell count was 4.6-5.0 log CFU/g on 0 day and continuously increased during the storage period. It had increased to 8.9-9.5 log CFU/g on the seventh storage day, and no differences were shown according to the additive content of Ulmus pumila L. extract. (3) On the sensory characteristics of Ulmus pumila L. nonglutinous and glutinous sikhe, the Ulmus pumila L. nonglutinous sikhe to which 20% Ulmus pumila L. extract was added showed the highest overall-acceptability value (4.23±0.95), whereas the Ulmus pumila L. glutinous sikhe to which 40% Ulmus pumila L. extract was added showed the highest overall-acceptability value (3.95±0.95). The sikhe to which 20 and 40% Ulmus pumila L. extracts were added showed significantly high taste, flavor, sweetness, and overall-preference values (p<0.05).
