To develop a yogurt for sensitive consumer such as infants, children or immuno-compromised patients using gamma irradiation, the effects of gamma irradiation on the microbiological, chemical, and sensory quality in a commercial plain yogurt were investigated. No viable coliform bacteria were detected in the sample and approximately a 6 decimal reduction was achieved in the number of total aerobic bacteria by irradiation at 5 kGy. The initial population of lactic acid bacteria observed in the commercial plain yogurt was 8.95 log CFU/g. Gamma irradiation significantly reduced the initial microbial level to 6.47 and 2.85 log CFU/g after irradiation at 1 and 3 kGy, respectively (p<0.05). However, irradiation dose up to 5 kGy could not completely eliminate the lactic acid bacteria in commercial plain yogurt. pH, color, lactose and lactic acid content, and sensory quality were not affected by irradiation treatment and storage. Our results suggest that irradiation can improve the microbial quality of commercial plain yogurt without impairing the physicochemical and sensory quality.
Exposure assessment for three major active ingredients used for humidifier disinfectants, polyhexamethylene guanidine (PHMG), oligo(2-(2-ethoxy)ethoxyethyl guanidinium chloride (PGH), and 5-chloro-2-methylisothiazol-3(2H)-one/2-methylisothiazol-3(2H)-one (CMIT/MIT) mixture, was conducted in a bedroom using an air sampler for a refined risk assessment. The experimental site was selected to reflect consumer exposure conditions. Aerosols formed by a humidifier were sampled during 8 hr at 7.5 L/min. Absorbed PHMG and PGH by the sampler were quantified using a spectrophotometric method, and high performance liquid chromatography-ultraviolet detection was used for CMIT/MIT. Three exposure scenarios were assumed for adding humidifier disinfectants to the humidifier water at 1, 2, and 10 times the volume recommended by the product suppliers, and the humidifier was on at its maximum rate of producing aerosols in order to consider reasonable worst-cases. The sampled mass of PHMG and PGH ranged 200 to $2,800{\mu}g$ and 140 to $1,900{\mu}g$, respectively, under different exposure conditions, whereas the absorbed mass of CMIT/MIT was barely detected at the detection limit of 0.11/0.29 mg/L, only at 10 times the recommended level. The resulting risk quotients for PHMG and PGH ranged 1,400 to 20,000 and 1,000 to 13,000, indicating that health risks could be significant. For CMIT/MIT mixture, risk quotients were much smaller than estimated by assuming that they are conservative in the indoor environment, probably due to oxidative reactions. The refined exposure assessment presented here may provide a useful tool for assessing risks posed by active ingredients in spray-type biocidal products.
The foodservice industry is applying new marketing strategies, and advertisements are the best way to convey their distinctive brand images. The foodservice companies have been choosing a type of advertising called Product Placement(PPL) because it is unconsciously shown more often than other types of advertisements while customers are watching a movie or TV drama. Therefore, the aims of this research were to investigate the influence of the customers' perception of PPL inserted into TV dramas on brand image and purchasing intention. Additionally, present study performed to identify the differences between Korean and Chinese customers. For the survey, the study used both offline and online sampling methods, and the analyzed data was from 150 Korean and 150 Chinese respondents. As results, the more respondents were positive and familiar about PPL, the higher the brand image and purchasing intention. Chinese consumers had positive perception of PPL, which positively influenced the brand image and purchasing intention while Korean consumers' ethical awareness about PPL had a negative influence. Therefore, the Korean foodservice industry needs to differentiate the strategies for the PPL marketing between the Korean and Chinese market.
This research was to investigate the role of message regulatory focus on the advertising effect of multiple models. The multiple models are limited to two models in one advertisement in this research. This research investigated the hypothesis that multiple models, in terms of multiple source effect and social consensus, appears specifically to enhance the relationship of consumer and commercial models on the conditions of promotion-focused message which leads to the information processing of relational elaboration. This research applied a between-subjects factorial design targeting 2(the number of model: single model vs. multiple models) by 2(message regulatory focus: promotion-focused message vs. prevention-focused message). As a result, multiple models showed more positive ad attitude, brand attitude, and purchase intention than did single model. And promotion-focused message with multiple models showed more positive ad attitude, brand attitude, and purchase intention than did prevention-focused message with multiple models. Also there was an interaction effect between the number of model and the type of message regulatory focus. It wasn't fully supported that there is no difference of advertising effect between promotion-focused message and prevention-focused message on the condition of single model.
The 21st century has been changed into a knowledge-oriented society, which means our society is more dependent on information and moves toward information. The mixing of broadcasting and co mmunication prevails and it makes possible a new type of broadcasting service. Depending on that, a broadcasting is being changed into a consumer-oriented service to satisfy the demands of consum ers in a new media age. It makes us attain to the personal media age to be possible interactive com munication unlike existing one-way transmission. As a result, new complex media are commercialize d and the instance is DMB. DMB is said 'my own TV' or 'TV in my own hands'. But it has limit t o retransmit existing broadcast programs. So hereafter, DMB broadcasting must be produced with co ntents suited its properties out of retransmitting existing contents. It is necessary to analyze exactly properties and service fields of DMB media to make an establish production direction of contents for DMB. This paper intends to suggest overall optimized image-contents production direction including appropriate program developments, a proper running time, visual expressions such as a camera angle and walking etc... DMB contents suited with its properties will give more familiarities to DMB users. Besides, DMB is expected to be a new culture watching broadcasting.

Recently, the strategy for N-screen service is in the spotlight along with the consumer's need to use contents regardless of time and place due to the rapid development of communication technology, which is meshing with the desire of service providers seeking a new business model. N-screen, as a screen-extension-concept service which enables consumers to continuously share and use contents in various equipments such as TV, computer and portable terminals, is an advanced type of 3-screen service strategy initially proposed by AT&T, an American telecommunication company. In the N-screen service for pay-contents, in order to support continuous screen changes to and from various equipments, temporary watching right should be given to the equipment intended for screen change. However, it is impossible to give the temporary watching right in the present broadcasting environment, adopting an access-control system. In this paper, the access-control technology being used for pay-contents in the present broadcasting environment and the reason for not being able to give temporary watching right, will be examined. After the examination, the solution for delegation of watching right by using an additional key on the basis of currently used access-control technology, will be proposed.
This study was conducted to classify Korean native chicken(KNC) and imported chicken by phenotypic performances and DNA fingerprinting. Two lines, KNC and White Leghorn(WL) , of chicken were maintained in the laboratory of Yeungnam University. Economic traits (body weight, sexual maturity, hen-day egg production, egg weight) and phenotypic characteristics (body-type, head, feather, shank) were checked. The DNA fingerprinting was analyzed for both breeds. The growth rate of the KNC was similar to WLS and sexual maturity of the KNC came later than WL. Hen-day egg production of the KNC was also slightly lower than the WL. The egg weight was about 10g lighter than WL. There was no difference in body weight of female KNC compared to the WL after 28 weeks. The study confirms difference between KNC and WL in DNA fingerprinting as well as its outlook. Thus, we suggest that these should be tested in nationwide districts about chickens known as the KNC using DNA fingerprinting. Then, the confirmed KNC populations should be maintained and used for the genetic improvement. Finally, only confirmed KNC should be in market which induce consumer to seek the KNC by its favorite.

It is well known that water holding capacity plays an important role in processing such meat products as frankfurter-type sausage and fish meat paste products as kamaboko and fish sausage. Consumer qualities of meat products, such as appearance, flavor, as well as drip and shrinkage on cooking, depend greatly on the degree of water binding. In this paper, the water holding capacities of fish paste and salt added paste of white corvenia, Argyrosomus argentatus and file fish, Novodon modestus were measured by centrifuging and press method before and after cooking. And the effects of the addition of phosphates and starch to enhance water binding and stabilize gel formation were also discussed. In addition, the experimental conditions which are suitable to determine the water binding of fish meat paste product were suggested. The results were expressed in percent of water absorbed by the filter paper when pressed or released by pressor or centrifuge to the weight of sample. From the results. a proper condition to measure the water holding capacity of fish meat paste was that 3.0 g of sample which was previously added with 10 percent water was centrifuged at 13,400 G or 12,000 rpm for 15 minutes for the centriguging method and for press method, 0.3 g sample with 10 percent of water added was extracted by an oil pressor at $30\;kg/cm^2$ for 1 minute. Water holding capacity of fresh paste of white corvenia was relatively higher than that of file fish and the difference between species of fish was greater than the difference between measurments by two methods. Sodium chloride had a great effect on enhancing the water holding capacity of fish meat paste giving better effect when 3.0 percent of salt was added. Phosphates used except calcium phosphate revealed a certain enhancement in water binding, yielding best effect at 0.3 percent addition, and metaphosphate seemed to be more effective in order. The addition of corn starch, however, appeared to be not so effective for enhancement of water binding in fresh-salt-added fish meat paste but in cooked fish paste which might be attributed to absorption of water by starch grain and swelling during the heating and consequently enforced gel strength of cooked fish paste. And the water holding capacity of cooked fish paste was proportionally related to its gel strength.
In our study, we investigated the effects of position of endorser and endorser's gaze direction(direct/averted_image/averted_text) on advertising attitude, purchase intent and brand recognition using eye-tracking method. Focusing on the printed cosmetic ads which the role of endorser is important and indirect persuade route is relatively is emphasized, we conducted experiment on 36 participants in 20s. As prior studies, our results shows that participants paid attention to more and faster on specific element which the endorser is gazing at. But it was not reflected to ad attitude and purchase intent directly. When the endorser is positioned in left the side, the highest purchase intent was shown in direct gaze condition, while when the endorser is on the right side, the highest ad attitude was shown in gazing image condition. Additionally, the brand recognition task following eye-tracking experiment shows that recognition accuracy was higher only in condition which the endorser is in the left side looking at the product image. These results demonstrated that the gaze direction of endorser plays a role as attentional guidance, which means it can lead customer's attention to particular region in the printed ad, but the effect can be varied depending on the position of endorser and which type of information the endorser is gazing at. Therefore, ultimately, to increase customer's ad attitude and purchase intent, complex consideration of not only the gazing direction of the endorser, but the position of endorser and other diverse elements is necessary.

This study examines the modern succession, transformation and significance of enjoyment methods of classical literature (art) with a focus on the characteristics of those methods that appeared when the performances of the traditional era began to be displayed on the stage of the theaters in modern Seoul. The clues to the reasons for this type of enjoyment can be found in newspapers, magazine articles, and advertisements from the early 20th century. The emergence of stage theaters at the beginning of the modern era caused a sweeping change in the performance environment, including the fact that it was possible for all kinds of people to enjoy art beyond the existing socioeconomic hierarchies or barriers of status, that the performers were given employment through the theater, and that the audience had the tendency of the general public of an unspecified number because the audience was able to see the performances only by paying the viewing fee. The way of enjoying traditional performances also changed based on these new adaptations: the performances were sequential, show-oriented, and re-contextualized as public performances. It is significant that in the traditional era, performers and audiences had been segregated according to their status and a strict hierarchy; now, such cultural norms were breaking down in favor of a kind of equality. In addition, it was possible for the audience to experience sensory enjoyment, and theater brought about a new kind of popular consumer enjoyment of an artistic product. Of course, though, it is possible to look back and find problems related to the contemporary context, but the traditional performances, which were the main performances for the lower class, took the first place on the modern theater stage, and as a result, no one can deny that it became possible to move forward in the first phase of an era of public performance.
