As the range of the customer choice becomes more diverse, the average life span of companies' products and services is becoming shorter. Most companies are striving to maximize the revenue by understanding the customer's needs and providing customized products and services. However, companies had to bear a significant burden, in terms of the time and cost involved in the process of determining each individual customer's needs. Therefore, an alternative method is employed that involves grouping the customers into different categories based on certain criteria and establishing a marketing strategy tailored for each group. In this way, customer segmentation and customer clustering are performed using demographic information and behavioral information. Demographic information included sex, age, income level, and etc., while behavioral information was usually identified indirectly through customers' purchase history and search history. However, there is a limitation regarding companies' customer behavioral information, because the information is usually obtained through the limited data provided by a customer on a company's website. This is because the pattern indicated when a customer accesses a particular site might not be representative of the general tendency of that customer. Therefore, in this study, rather than the pattern indicated through a particular site, a customer's interest is identified using that customer's access record pertaining to external news. Hence, by utilizing this method, we proposed a methodology to perform customer segmentation. In addition, by extracting the main issues through a topic analysis covering approximately 3,000 Internet news articles, the actual experiment applying customer segmentation is performed and the applicability of the proposed methodology is analyzed.

We investigated colonization and extinction patterns in a meta population of the gold-spotted pond frog (Rana planeyi ehoseniea) near the Korea National University of Education, Chungbuk, Korea, by surveying the frogs in the nine occupied habitat patches in the study area four times per breeding season for three years (2006$\sim$2008) and recording whether the patches were occupied by frogs as well as how many frogs were calling in the patches. We then developed five a priori year-specific models using the Akaike Information Criterion (AIC). The models predicted that: 1) probabilities of colonization and local extinction of the frogs were better explained by year-dependent models than by constant models, 2) there are high local extinction and low colonization probabilities, 3) approximately 31% number of patches will be occupied at equilibrium, and 4) that considerable variation in occupation rate should occur over a 30-year period, due to demographic stochasticity (in our model, the occupation rate ranged from 0.222 to 0.889). Our results suggest that colonization is important in this metapopulation system, which is governed by mainly stochastic components, and that more constructive conservation effects are needed to increase local colonization rates.

This study investigates differences in demographic characteristics, shopping orientation, perceived risk, and satisfaction after purchase among consumer types. This study classifies consumer types according to their channel transition behaviors between the online and offline channels with a focus on the steps of information research and buying decision in buying decision-making process. The four consumer groups are as follows: off-off type (offline research-offline purchase), on-on type (online research-online purchase), on-off type (online research-offline purchase) and on/off-off type (online and offline research-offline purchase), off-on type (offline research-online purchase) and on/off-on type (online and offline research-online purchase). Data were collected from adults over 20 years old who had bought clothes within one year. The questionnaire was carried out from July, 2019 using a professional internet research panel; in addition, 500 sets of useful data were analyzed by descriptive statistics, factor analysis, reliability analysis, chi-squared test, ANOVA and Duncan-test using SPSS 21.0. The findings showed significant differences among the classified consumer groups for consumer demographics, shopping orientation, perceived risk, and purchase after satisfaction. The results imply that consumers show a variety of channel transition behaviors based on demographic variables, shopping orientation, and perceived risk. Understanding and adapting to consumer purchase behaviors will allow company distribution channels to be effectively managed and eventually increase consumer satisfaction as well as company sales volume.

This research was conducted to activate the horne shopping by providing the basic data about demographic characteristics, purchase practices and satisfaction degree of women consumers. The subjects were 328 women consumers residing in Cheongju who had purchased apparel products through home shopping. Collected data were analyzed by frequency analysis, t-test, analysis of variance, and cross-tabulation analysis using SPSS. The results were as follows: 1) When purchasing formal wears, casual wear and furnishing textile products through home shopping, respondents considered the design and fiber content seriously, and when purchasing underwear, the fiber content and size. 2) When purchasing apparel products, most of respondents confirmed apparel labels, and married women confirmed more than single women did. Among apparel labels, fiber content, care symbol, and size were the items that respondents considered most. 3) The single women managed internet and knew the value of internet in searching information or purchasing apparel products better than married ones. 4) When purchasing apparel products via home shopping, respondents used TV, catalog, and internet in order. 5) Degree of satisfaction for clothing purchased via home shopping was in ordinary level, high for furnishing textile products and low for formal wears.

The world is changing drastically by digital information technology and ubiquitous networking. Meanwhile, with the demographic avalanche, South Korea officially became an 'ultra-aging society' in 2026. Simultaneously, this demographic change will also stimulate a cultural climate which facilitates the formation and dissemination of 'slow culture' from the existent urban 'fast culture' which has been weakening the retirement living. One of the fundamental connections with the slow movement appears in the cooking and dining area. With this point of view, this study aims to identify the needs and behaviors of the elderly in current restaurants and a digitally planned multi-purpose one for the future. Small group workshop was employed for this study. In order to elicit detailed information from the elderly group members, scenarios were developed. A group facilitator kept the discussion on track by asking a series of open-ended questions meant to stimulate discussion. As the results, it was revealed that the elderly were interested in digitally planned restaurant which provides one-stop service including entertainment activities, health related contents and socializing with family. Even though this study took restaurant scenarios, the ideas in them also provide holistic perspectives on the direction of marketing and planning strategies on various future environments and services.

The aim of this study was to assess University students' consumption pattern of Korean rice cakes and to analyze the preference of Korean rice cakes by their demographic backgrounds. The results of this study will be useful information for systematic development and wide distribution of Korean rice cake as a traditional Korean food. A self completed survey of 392 University students in Seoul was undertaken and detailed information was collected. The survey questionnaire consisted of three parts including demographic backgrounds, student's consumption pattern and preference of Korean rice cakes by type. Approximately half of the students were male (52.6%) with the average age of 21.1 years old. Most of the respondents (92.3%) were from nuclear families. The consumption frequency rate showed that 38.8% students had Korean rice cake once or twice a month followed by once a week (29.8%), once per six months (21.7%), and once per two months (8.2%). Ingeolmi received the highest preference score (4.15), whereas Duteopteok had the lowest score (0.18). The correlation coefficient for paired samples between students' preference of Korean rice cake and their knowledge of them was 0.827, showing statistically strong positive correlation between them.

The purpose of this study is to investigate the general tendencies and casual relations of demographic variables, consumer alienation, materialism and impulse buying among college students. Three hundred and forty one undergraduate students in Daejeon were participated in this study. Factor analysis, Multiple regression and Path analysis were used as statistical analysis. The major findings are as follows: 1. Consumer alienation of college students was divided into 4 types such as Powerlessness, Meaningless, Normlessness, Cultural Estrangement. The overall level of consumer alienation was 3.36. Normlessness(M=3.70) was the highest, and the lowest was powerlessness(M=2.82). Consumer alienation was influenced by gender, age, subjective level of living. Specifically, the lower the age and the subjective level of living were the higher meaningless and powerlessness respectively. And cultural estrangement was higher in male than female. However, normlessness was not affected by demographic variables. 2. The level of materialism of college students was relatively high(M=3.71). The materialism was affected by gender, age, allowance adequacy. 3. The level of impulse buying was higher than middle point(M=3.29). The results of path analysis showed that gender, age, allowance, allowance adequacy, socio-economic status, subjective level of living, powerlessness, materialism influence on impulse buying direct and indirect.
