  • This article addresses the 2nd Korean consensus conference on cloning that was held by the Korean National commission for UNESCO in 1999. Though previous perspectives recognized the conference as a new citizen's participatory institution. they do not consider that it contains the ideal of deliberative democracy. This article notes that the citizens participated directly and handled the important social agenda through debate in the consensus conference. The consensus conference is another democratic form derived from preference aggregating democracy in the sense that it basically depends on public judgement of the citizens. This consensus conference has the historical meaning because it is in fact the first experiment of deliberative democracy in Korea. 1) We examine the theoretical foundations of consensus conference. They are social constructionism of science, the tradition of societal debate, and deliberative democracy. 2) We explore what deliberative democracy is. It is different from aggregating preference democracy in the sense that it depends on public judgement rather than private preferences. 3) We investigate the features and meaning of deliberative democracy which has experiment on the conference. In the Consensus Conference it was observed that citizens changed their preferences and went forward to developing their view of community as a result of the process of deliberation. It can be said to confirm the significance of deliberative democracy. However, it is simultaneously an opportunity to clarify some problems of deliberative democracy. First of all, it shows that there were hierarchies within the citizens' panel as well as between the citizens' and the specialists' panels. Secondly, there are difficulties in expressing the value of life in argument or discourse. Also, we need the institutional efforts concerning future generations and nonhuman beings in the respect that cloning relates to them.

  • This study aimed to determine the effects of floral fragrances on human brain waves and moods. A total of 44 subjects participated in this experiment. Group 1 consisted of 11 male and 14 female college students with a mean age of 24.5 years (${\pm}2.23$) and Group 2 consisted of 10 males and 9 females with a mean age of 54.3 years (${\pm}2.98$). Subjects were exposed to floral fragrances of Rosa hybrida, 'Hera' (hereafter referred to as "rose"), Cymbidium faberi (hereafter referred to as "orchid"), or odorless control flowers (hereafter referred to as "control"). Experiments took place in three rooms (rose, orchid, and control). Electroencephalographs (EEGs) were recorded during exposure to the odors and the data were processed using quantitative electroencephalographic (QEEG) techniques. The changing EEG patterns were analyzed by brain mapping and compressed spectral arrays, and the subjects' preferences (hedonic evaluations) were quantified with an A1 index. Increased activation of absolute alpha waves was verified on six of the eight EEG channels, with the right frontal and left occipital lobes exhibiting no changes and the left parietal region showing the greatest activation. According to the QEEG measurements in the electrode sites over the frontal, temporal, parietal, and occipital lobes, the strongest absolute alpha waves were induced in the parietal lobes, followed by the temporal lobes, with the other lobes showing no significant changes. On brain maps, the orchid fragrance induced greater absolute alpha and absolute mid-beta activities compared with the rose and control fragrances, and the rose fragrance induced high absolute mid-beta activation. To identify emotional responses to floral fragrances, the subjects were requested to fill in a questionnaire and the resulting odor-related emotional descriptors were analyzed using semantic differential and factor analysis. Principal component analysis identified "elegant" as the first principal component describing the floral fragrance, followed by "refreshing" and "aromatic." The subjects gave orchid higher scores for "elegant" and "refreshing," while finding rose more "aromatic." Differences in hedonic evaluation revealed by the A1 index appeared in the 65-115 sec range of scent exposure time. The subjects with ages of around 50 years showed olfactory preferences throughout the entire experimental time of 160 sec, most markedly in the later time segment (115-165 sec), showing an increasing preference with increasing exposure time. We conclude that rose fragrance can improve concentration by creating an aromatic environment conducive to a concentrated and calm state of mind, and orchid fragrance can make people feel pampered and relaxed by creating an elegant and refreshing environment.

  • Chicken dominates meat consumption because it is low in fat and high in protein and has less or no religious and cultural barriers. Recently, meat quality traits have become the focus of the poultry industry more than ever. Currently, poultry farming is focusing on meat quality to satisfy meat consumer preferences, which are mostly based on high-quality proteins and a low proportion of saturated fatty acids. Meat quality traits are polygenic traits controlled by many genes. Thus, it is difficult to improve these traits using the conventional selection method because of their low to moderate heritability. These traits include pH, colour, drop loss, tenderness, intramuscular fat (IMF), water-holding capacity, flavour, and many others. Genome-wide association studies (GWAS) are an efficient genomic tool that identifies the genomic regions and potential candidate genes related to meat quality traits. Due to their impact on the economy, meat quality traits are used as selection criteria in breeding programs. Various genes and markers related to meat quality traits in chickens have been identified. In chickens, GWAS have been successfully done for intramuscular fat (IMF) content, ultimate pH (pHu) and meat and skin colour. Moreover, GWAS have identified 7, 4, 4 and 6 potential candidate genes for IMF, pHu, meat colour and skin colour, respectively. Therefore, the current review summarizes the significant genes identified by genome-wide association studies for meat quality traits in chickens.

  • This study analyzed the quality characteristics of the Sansapyun products, which were manufactured by mixing with 0, 5, 10, 20, and 30% of Crataegi fructus concentrate and 9% of mung bean starch. The moisture content and pH in Sansapyun decreased significantly(p<0.001) as the concentration of Crataegi fructus concentrate increased. Sweetness increased as the amount of Crataegi fructus concentrate increased in both Before/After cases. As for the L value of the color characteristics of Sansapyun, it turned out that the control group, which had 0% of Crataegi fructus concentrate, was higher. Meanwhile, the a and b values were the strongest with 30% of Crataegi fructus concentrate. As the concentration increased, the hardness, springiness, chewiness, gumminess, cohesiveness all decreased significantly(p<0.001), while adhesiveness became higher as the concentration increased. The preference test showed that the increase of the concentration resulted in the increase of red color, fruity flavor, sour flavor, Chinese (herb) medicine flavor, sour taste, sweetness, Chinese (herb) medicine taste, stickiness, and aftertaste. However, the sleekness, transparency, hardness and springiness decreased as the concentration increased. The survey on the preference showed that the preferences for flavor, taste and overall preference were the highest at the 10% sample group, but the preferences for color and texture were the highest at the 20% sample group.

  • Background: The use of dental floss along with a toothbrush is a well-known oral hygiene product that effectively removes dental plaque and reduces the risk of dental caries and periodontal disease. Despite the fact that various types of floss are being used, flossing methods based on the thread type are being taught. In addition, personal preference according to the floss types has not been investigated. In this study, individual preferences according to the floss types were investigated by experiencing various types of dental floss to both floss users and non-users. In addition, the change in intention to use dental floss in the future after flossing experience of non-users was investigated. Methods: General public participated in the individual interview survey (n=419). Subjects responded to the questionnaire after using all of the thread type, Y-type, and C-type floss. All statistics were expressed frequencies and percentages for categorical variables, and the chi-squared test was used to determine the statistical significance of associations between the variables. Results: As a result of the analysis, the preference of C-type floss was highest in both floss users and non-users. The biggest reason for not using dental floss was not knowing the necessity of flossing (36.4%). In addition, both floss users and non-users responded that C-type floss was suitable for flossing in the anterior and posterior regions. The change in the positive future intention to use dental floss after flossing experience of non-users was statistically significantly associated with age. Conclusion: This result suggests that there is a need to provide education on how to use dental floss in various forms. Based on this, it will be possible to lead a change in individual's attitude for future oral health through active and continuous flossing experience.

  • With the increase in a number of access technologies and data rates, a continuous connection among different networks is demand of the future wireless networks. In the last decade, user connectivity among different access networks remained a challenging job. Therefore, in this article, we proposed a user-centric and user-perspective based network selection mechanism for fast handover management in heterogeneous wireless networks. The proposed scheme selects the most appropriate network among available networks on the basis of resources i.e. cost, data rate, and link quality. Initially, we load the Media Independent Information Service (MIIS) with the information of cost and data rate provided by different network operators. Similarly, Mobile Node (MN) is also loaded with the user preferred cost and data rate for different applications. The MN obtains the information of cost and data rate from MIIS server upon a predefined threshold, and make a decision for handover according to its current cost and data rate. Furthermore, we employ an optimal threshold mechanism for initiation of the handover execution phase to minimize false handover indications. The proposed scheme is based on a survey for network selection and its implementation in C programming language to validate its performance and accuracy. The simulation result shows that the proposed scheme performs superior then the schemes present in the current literature.

  • This study was conducted to raise awareness of careers in the Department of Library and Information Science (LIS) as well as to investigate current awareness and preferences for LIS Department as a strategy to cope with the rapidly changing university environment. To do this, a survey of high school students was carried out, with results as follows: First, awareness about the LIS Department and awareness about librarians in our country's high school students was very low. Second, for possible careers in LIS Department, students responded that a graduate of LIS department was likely to enter the workplace in public libraries, state libraries, university libraries, or school libraries, but they would like to work at broadcasting library, national libraries, school libraries, university libraries, public libraries, or portals. Third, awareness of the career path for the LIS Department showed a very large impact on a preference for the LIS Department. Therefore, students who have heard about the LIS Department are highly probable to select this department when they reach university.

  • This study was conducted to evaluate children's purchase behavior (frequency of snack consumption and purchase) and preference for high protein snack products developed for weight control and nutritional balance. A total of 80 elementary school students (from the 3rd to 6th graders) in the Gyeonggi-do learning center were participated and 76 were used for the analysis. The most common response for liking snacks was taste (71.4%), and the most preferred types of snacks were chips (42.1%) and puff snacks (34.2%). The highest frequency of snack ingestion was 1-3 times per week (48; 63.2%), and the main purchasers were parents (65.8%). Cheese, corn and chili flavors were more preferred than the control, while yogurt taste was slightly less preferred than the control. The results of this study showed the possibility of commercialization of new protein snacks according to children's seasoning preference and provide the insights into the snack preferences of children as main consumers.

  • This study was performed to identify the tendency and benefits of outdoor recreation in rural areas. The preferences and importance of the benefits of outdoor recreation activities in rural areas were simultaneously compared and analyzed through the discussion of a four quadrants portfolio map using importance-performance analysis. The social benefits in quadrant i had the characteristics of 'sharing nice experiences with others', 'having contact/interchange with others', 'colleagueship/helping each other', 'being together with friends', and 'making new friends.' These social benefit types were perceived as very important characteristics, but the real level of achievement was rather low. Thus it seems necessary, in the process of program development, to apply the social benefit types to the characteristics of the participants. The experience of nature and relaxation benefits in quadrant ii had the characteristics of 'relaxation and recreation', 'understanding nature', 'nature experience', 'getting away from everyday life', and 'experiencing new things.' These benefits and experience of nature were regarded as very important characteristics by the participants in outdoor recreation and, at the same time, their real achievements were highly recognized, thus they seemed to be proper types for the goals involved in developing an outdoor recreation activity program in rural areas. The personal and challenge benefits in quadrant iv had the characteristics of 'training of mental ability', 'improvement of self-esteem', 'fitness', 'increase in determination', 'possible danger', 'achievement', 'excitement', and 'adventure.' These benefits had less importance to the participants, but had relatively high achievement, thus it might be important to make further suggestions for the direction of development according to the participants' tendency, seasons and facilities.

  • Currently, the rewards programs offered by many companies to strengthen customer relationships have been working quite well. In addition, many companies' rewards programs, designed for stabilizing revenue, are recognized to be effective. However, these rewards programs are not significantly differentiated between companies and there are no accurate conclusions currently, which can be made about their effects. Because of this, a company with a customer rewards program may not comprehend the true level of active participation. In this environment some companies' rewards programs inadvertently hinder business profitability as a side effect while attempting to increase customer loyalty. In fact, airline and oil companies pass on the financial cost of their programs to the customer, and as a result, they have been criticized publicly. The result of this is that the corporations with bad rewards programs tend to get a bad image. In this study of stores' rewards programs, we centered our focus on the design of the program. The main problem in this study is to recognize the financial value of the rewards program and whether it can create a competitive edge for the companies despite the cost issues experienced by them. Customers receiving financial rewards for their business may be just as satisfied with a particular company or store versus those who are not, and the program, perhaps, does not form a distinctive competitive advantage. When the customer is deciding between competing companies to secure their product needs with, we wanted to figure out how much of an affect a valuable reward program had on their decision making. To evaluate this, we set the first hypothesis as, "based on the level of involvement of the customers, there is a difference between customers' preferences for rewards programs." In the results of Experiment 1 we saw that in a financial compensation program for high-involvement groups and low-involvement groups, significant differences appeared and Hypothesis 1 was partially supported. As for the second hypothesis that "customers will have different preferences between a financial rewards programs (SE) and a joint rewards programs (JE)," the analysis showed that the preference for JE was significantly higher than that for other programs. In addition, through Experiment 2, we were able to find meaningful results, which revealed that consumers have shown a significant difference in their preferences between SE and JE. The purpose of these experiments was to enable the designing of a rewards program by learning how to enhance service information distribution and strengthen customer relationships. From the results, there should be a great amount of value for future service-related endeavors and academic research programs. The research is significant, because the results can be found to have a positive effect on reward program designs however, it does have the following limitations. First, this study was performed using an experiment, and all experiments have limitations. Second, although there was an individual evaluation and a joint evaluation, setting a proper evaluation criteria was difficult. In this study, 1,000 Korean won (KRW) in the individual evaluation had a value of 2 points, and, in the joint evaluation, 1,000 KRW had a value of 1 point. There may have been alternative ways to differentiate the evaluations to obtain the proper results. In this study, since there was no funding, the experiments were performed orally however, this was complementary to the study. Third, the subjects who participated in this experiment were students. Conducting this study through experimentation was unavoidable for us, and future research should be conducted using an actual program with the target customers.
