This study investigates the actual wearing conditions of functional mountaineering garments in Korea and provides suggestions on the development of more effective functional mountaineering garments through the examination of consumer data. This survey was based on 107 respondents who enjoy mountaineering and was composed of 5 sections consisting of personal information, purchasing habits, essential features for mountaineering garments, satisfaction levels based on features and functions, and additional comments on the improvement of mountaineering garments. Respondents said that essential features for mountaineering garments are quick absorbing/drying, insulation, water and wind proof, and elasticity. These properties become more effective when users wear mountaineering garments in layers. They want lower prices and easy to wash garments. Therefore, it is necessary to consider not only the main functions, but also the needs of consumers for easy washing and price.

While online shopping has been increased expeditiously, a significant portion of purchasing intention has not been converted into actual purchasing behavior without delay in online space. This study investigates the factors causing a delay in online purchasing decision even after purchasing intention has been formed. It identifies the uncertainty variables (information, psychological, and preference uncertainties) related to consumer needs and the situational variables (time pressure and past purchase experience) surrounding the purchasing transaction. Furthermore, the need for cognitive closure is proposed to moderate the relationships between uncertainty/situational variables and the purchasing behavior. The results show that the uncertainties and situational factors significantly influence purchasing delay. Also, the need for cognitive closure indeed works as a moderator between the uncertainty variables and the purchasing behavior. Practical and academic implications of these findings are also discussed.

Cloud-based streaming game service has numerous merits, but it may suffer from presentation latency in a thin-client. It is an important issue especially for game service which needs instantaneous response to user inputs. This research proposes the methods for reducing the presentation latency between the server unit and the thin-client unit. The approaches proposed to be employed with server unit include the source/sync video format equalization, encoding format configuration according to the media type, and the S/W implementation for transmitting clock periodically. The methods for the thin-client unit include the decreasing the number of instructions, use of light encryption algorithm, and improvement on H/W decoding. The proposed schemes are tested with a commercialized streaming service platform, which reveals the reduction of presentation latency as large as a few hundred milliseconds and reaches the acceptable level (about 100 milliseconds).

In the modern era of digital sophistication, effective public administration warrants a citizen-centric approach that not only anticipates the needs of public service users but also comprehends their behaviors in undertaking proactive measures to deliver public services as needed. This study adopts a typological perspective by viewing e-government users as distinct consumer groups with individualized demands, behavioral tendencies, and perceptual attributes. Utilizing data from a 2021 survey on e-government service utilization, a two-step cluster analysis was conducted to delineate user typology through an empirical study. The analysis incorporated variables such as the purpose of using e-government, selected e-government channels, subjective perceptions of technological risk, and personal innovativeness. Accordingly, e-government users were classified into five distinct typological groups labeled "Unilateral Active Users Geared to Social Media," "Versatile Power Users," "Unilateral Pragmatic Active Users," "Occasional Passive Users," and "Minimal Users." This typological differentiation of e-government user groups is intended to help identify unique user demands and characteristics so as to facilitate the delivery of tailored e-government services and informed policy decisions catering to the diverse needs of users.

The purposes of the study were to identify satisfaction and achievement of learning by female learner's characteristics, and to suggest measures to improve quality of education in internet education programs. In order to determine the educational effectiveness associated with the characteristics of learners, this study attempted to employ two way approaches by observing the degree of achievement for learning, which represents an instructor-oriented approach, and the degree of satisfaction for education, which represents a learner-oriented approach to enhance the quality of internet education for female learners. As an approach to evaluate the educational effectiveness, the degree of achievement in learning(Tyler's classical approach), and the degree of satisfaction for education (Scriven's consumer-oriented evaluation model) were utilized. A survey form was developed by the researcher after reviewing the various tools originated from Boshier, Cross, Gagne and Choi, and distributed to a panel of judges that examined the content validity of the instrument. The sample for the study consisted of 160 female learners from three universities in Seoul and capital area, and the survey form was used to collect data for this study. The SPSS WIN program was used in analyzing the data and a series of statistical tests were conducted including frequency, percentile, t-test, ANOVA, correlation, multiple regression, and factor analysis. The statistical significance level was 0.05. The following conclusion were drawn from this study of female internet education. First, it was evident that female internet learners tend to utilize information from internet, and this can be interpreted as participants' positive attitude, and voluntary participation. Second, educational facilities and services should be improved in the future, because the level of satisfaction was low in these areas compared to curriculum and educational methodology. Third, the participating factors influenced by the level of satisfaction for education of learner characteristics were the 'formation of inter-personal relationship and willingness to change' and the 'needs for education on internet', thus appeared that both social and educational needs influenced the level of satisfaction for education. Fourth, the degree of achievement in learning was higher in the order of 1) attitude 2) function 3) knowledge, thus, attitude change was the most important in achievement of learning. Fifth, the individual background that influenced the level of achievement in learning were age and educational experience. As for the individual level of achievement for learning, the younger and more educated group were more satisfied.

The nutritional value of kimchi is gaining global focus along with new possibilities and uses for the various salts used in making kimchi. The purpose of the study is to conduct research on the uses of various salts and investigate the consumer recognition of salt use in kimchi preparation. The findings are from 824 consumers over 19 years old from 15 locations who participated in this questionnaire via one-to-one interviews from September 23rd to October 14th, 2009. The results of the questionnaire show that when customers cooked, 71.9% used solar salt, 62.2% used flower salt (refined salt), 27.4% used Hanju salt (purified salt), 59.0% used processed salt (roasted salt), 47.4% used bamboo salt, 69.4% used Mat salt (table salt), and 18.2% used low sodium salt. The most preferred origin of salts was domestic. Most customers salted Chinese cabbage while preparing kimchi. Consumers showed low perceptions of different salts used in kimchi production, and did not exactly recognize the characteristics of various salts. The preferences for domestic and solar salts were very high, while the preference for sea salts was low. In conclusion, various types of salts could improve the quality of kimchi. This study hopes to help consumers produce better kimchi to match different needs. Therefore, attention should be paid to promoting the characteristics of various salts influencing the quality of kimchi.

Recently, technological differentiation(sensor, AI) of products using IoT technology to satisfy consumer needs in the mature market for smart home appliances has received a lot of positive responses. However, air conditioner products are in the early stages of convergence technology. Therefore, air conditioner products are fields that require ICT technologies for information production, collection, processing, storage, and service development beyond IoT. In this paper, we collect and store contactless bio-signal using IR-UWB radar technology. The blowing direction of the air conditioning is controlled according to bio-signal and user's sleep is monitored to provide an optimal sleep environment. In addition, we propose a service algorithm that can provide comfort with changes in the optimal conditions of air conditioning and emotional lighting depending on the discomfort index environment. Through this study, we developed an intelligent smart air conditioning service platform with ICT technology of bio-signal, discomfort index, and emotional lighting.

Unique organoleptic characteristics such as rich flavors and chewy texture contribute to the higher popularity of native chicken in many Asian areas, while the commercial broilers are well-accepted due to their fast-growing and higher yields of meat. Sensory attributes of foods are often used to evaluate food eating quality and serve as references during the selection of foods. In this study, a three-phase descriptive sensory study was conducted to evaluate the sensory attributes of commercial broiler (BR) and Taiwan native chicken (TNC) breast meat, and investigate correlations between these sensory attributes and instrumental measurements. The results showed that for the first bite (phase 1), TNC meat had significantly higher moisture release, hardness, springiness, and cohesiveness than BR meat. After chewing for 10 to 12 bites (phase 2), TNC meat presented significantly higher chewdown hardness and meat particle size, whereas BR meat had significantly higher cohesiveness of mass. After swallowing (phase 3), TNC meat had higher chewiness and oily mouthcoat and lower residual loose particles than BR meat. TNC meat also provided more intense chicken flavors. This study clearly demonstrates that descriptive sensory analysis provides more detailed and more objectively information about the sensory attributes of meats from various chicken breeds. Additionally, sensory textural attributes vary between BR and TNC meat, and are highly correlated to the shear force value and collagen content which influence meat eating qualities greatly. The poultry industry and scientists should be able to recognize the sensory characteristics of different chicken meats more clearly. Accordingly, based on the meat's unique sensory and physicochemical characteristics, future work might address how meat from various breeds could best satisfy consumer needs using various cooking methods.

Classifying clothing fabrics into fashion images lacks research, but is necessary due to the short cycle of fashion and rapidly changing modern trends as consumers seek to satisfy various needs with an increase of online purchases. There is also a lack of research on fashion trend books which attach real fabrics. Therefore, this study aims to help the planning field by recognizing fabric sensibility related to the fabric image perceived by consumers. The data analysis results from descriptive statistics, t-test, and ANOVA using SPSS are as follows: Differences in the visual tactility evaluation related to the consumer recognized fabric images showed more significant differences in F/W seasons. The elegance image was shown as relatively thick, the avant-garde image was shown as relatively heavy, thick fabric. The feminine image was shown as relatively thin and smooth fabric, the sporty images were shown to be moist, flexible and elastic, and the mannish images were relatively rough. The romantic images were shown as relatively thin fabrics. The conclusions inferred from the visual tactile evaluation related to the fabric images recognized by consumers vary by major, so the prior information concerning fabrics and trends can affect the selection of images. The results of this study show that in order to produce clothes suitable for fashion product planning by learning about visual tactility that consumers recognize, fabrics component data displayed in fashion trend books from 2016 to 2018 are needed, so the planner can receive help when selecting the fabrics suitable for each trend.
