The water consumption data of individual consumers must be analyzed and forecast to establish an effective water demand management plan. A k-mean cluster model that can monitor water use characteristics based on hourly water consumption data measured using automated meter reading devices and demographic factors is developed in this study. In addition, the quantification model that can estimate the daily water consumption is developed. K-mean cluster analysis based on the four clusters shows that the average silhouette coefficient is 0.63, also the silhouette coefficients of each cluster exceed 0.60, thereby verifying the high reliability of the cluster analysis. Furthermore, the clusters are clearly classified based on water usage and water usage patterns. The correlation coefficients of four quantification models for estimating water consumption exceed 0.74, confirming that the models can accurately simulate the investigated demographic data. The statistical significance of the models is considered reasonable, hence, they are applicable to the actual field. Because the use of automated smart water meters has become increasingly popular in recent year, water consumption has been metered remotely in many areas. The proposed methodology and the results obtained in this study are expected to facilitate improvements in the usability of smart water meters in the future.

Recently, increased caffeine intake has led to an increase in caffeine addiction and withdrawal symptoms. Coffee is surreptitiously consumed in as an additive to milk and caramel. There are few studies on how coffee affects the health of modern people. The purpose of this study is to determine the efficacy and side effects of coffee by awareness of coffee consumption patterns among college students, who are the principal consumers. A survey was conducted from May 11 to 17, 2015 and 302 questionnaires were analyzed. The respondents were 140 men (46.4%) and 162 women (53.6%). In terms of coffee additives, 151 (50.0%) respondents chose ‘americano’ and 111 (36.8%) ‘variation’. The frequency of coffee intake and sleep time for college students was negatively correlated, with the correlation coefficient of －0.145 and significance probability of 0.019. The group that was ‘positively’ aware of the principal ingredients of coffee had a higher level of academic training than those with ‘negative’ awareness (p=0.000). Women recognized a larger number of side effects than men: 1.99 and 1.36, respectively, on average (p=0.001). ‘Time for consumption’ had statistically significant effects on the side effects of coffee consumption: consumption before/after lunch, before/after supper and before going to bed led to 0.4 times (p=0.048) and 0.3 times (p=0.023) more side effects, respectively, than consuming coffee after getting up and before/ after breakfast. Excessive caffeine intake through coffee led to limited sleep time and poorer learning concentration. The guidelines for proper coffee consumption should be created to help students consume coffee properly so that it will not affect sleep, learning concentration or adversely affect health.

The purpose of this study was to determine the effects of awareness and knowledge of the efficacy of carbonated water on consumption patterns and satisfaction for college students, who are the principal consumers of carbonated water. A survey was conducted with 502 college students in the Metropolitan area from May 13 to 18, 2015 and 455 questionnaires were analyzed. As for the differences in awareness and knowledge of the efficacy of carbonated water according to gender, females (14.60 and 0.76) had better awareness and knowledge than males (13.40 and 0.58) (p=0.000 and p=0.036). The more positive the awareness of carbonated water, the greater the knowledge (p=0.000); the greater the knowledge of carbonated water, the higher level of consumption satisfaction (p=0.006). The odds ratio of awareness for carbonated water was 11.98; that is, positive awareness led to higher levels of satisfaction than negative awareness (p=0.003). Since awareness of the efficacy of carbonated water was found to affect carbonated water drinking and satisfaction, it is necessary to provide correct information about the efficacy of carbonated water.

This study is conducted to investigate to the consumption pattern of Kimchi and perception about the functional Kimchi of consumer. The survey was done between October 1 to October 15, 2011 among 294 male and female adults aged 19 and over in Seoul and Gyeonggi-do areas. The gender distribution of subjects was 33.3% males and 66.7% females. 64.3% of subjects prepared Kimchi by themselves, 23.5% of subjects received Kimchi from relatives and 12.2% of subjects purchased Kimchi from the market. In addition, the rate of preparing Kimchi at home is highest in those aged fifty or over. Only 41.8% of subjects knew how to make Kimchi. 72.1% of subjects responded that they ate Kimchi one or more a day. 46.6% of subjects have purchased commercial Chinese cabbage Kimchi. The amount of one-time purchase of commercial Kimchi were investigated; 45.2% of subjects have been buying 500-1 kg, 34.4% of the subjects bought less than 500 g, and 11.2% of subjects bought 1-3 kg. 28.2% of subjects buy Kimchi at the supermarket and warehouse market. With regard to the evaluation of Kimchi taste, most consumers were not satisfied with the sweetness of Kimchi. In this result, the perception about functional Kimchi was very low. Consumer's demands were as follows: nutrient enhancement, strengthening of biologically active substances, lactic acid bacteria enhancement in order. Small sales units were preferred by the consumers, and complementation of sweetness of kimchi was required. Various Kimchi including functional Kimchi must be developed to meet the needs of consumers.

The purpose of this study was to assess the consumption patterns of Makoli and to provide age-specific suggestions to increase the popularity of newly developed products. The subjects of the study were 373 men and 329 women, and information was obtained by self-administered questionnaire in December of 2010. One major finding of the study was that regardless of gender, consumption of Makoli was correlated to age: older respondents drank more Makoli. Those in their thirties and older, especially women, drank Makoli at home with family. The reasons given for liking or disliking Makoli differed among age groups, but were the same between genders. More subjects in their twenties liked Makoli because of its distinctive taste, while more in their forties liked it for its cultural value. Subjects in their thirties disliked it because it caused headaches, while more in their forties complained of burping. Both genders in their twenties suggested that TV and internet advertisements may be the best strategy to increase the popularity of newly developed Makoli products, and women in their forties suggested promoting Makoli’s health benefits. The low calorie content of new Makoli products appealed to women of all age groups and men in their twenties and thirties. Women in their forties were also attracted by Makoli’s possible effect to alleviate constipation.

The principal objective of this study was to evaluate the consumption behavior of housewives in the Jeonju area with respect to their use of environmentally-friendly agricultural products(EAPs) and to assess the need for EAPs in childcare centers also in the Jeonju area. Self-administered questionnaires were given to and collected from 278 housewives 42.4% of whom employed and 57.6% were unemployed. Statistical data analysis was performed on the data collected using SPSS v. 12.0. The average score of awareness about EAPs was 3.57±0.56. The percentage of subjects who purchased EAPS was 76.3% regularly. On this group, 40.3% purchased EAPs 1～2 times in week. Unemployed housewives purchased more than employed housewives by a statistically significant margin(p<0.05). The most-purchased EAPs were vegetables. The average satisfaction score that housewives reported in relation to foodservice provided in childcare centers was 3.66±0.58. About 65% of the respondents felt that the EAPs-foodservice in childcare centers was an important factor for them in choosing of a childcare centers. Approximately 42% of the housewives responded that EAPs-foodservice in childcare centers was needed to improve the safety of foodservice provided in chidcare centers. The percentage of subjects who wanted to expand EAPs-foodservice in childcare centers even though the parents would have to bear some of the financial burden was 42.5%. A higher proportion of employed housewives wanted to expand EAPs-foodservice in childcare centers more than unemployed housewives, and this finding was statistically significant(p<0.05).

This study was conducted to investigate the relationship between long naming of beverages and its effect on people's perception by gender. The survey was conducted in the Seoul area from March 10 to May 10, 2010. Approximately 59% of male and 41.8% of the female respondents were randomly selected from university students aged 20 to 29-years. Most (79.8%) of the students responding to the survey showed a preference for beverages. "Long-named beverages with ingredients listed" were considered the most reliable and ranked highest at 3.74, A significant difference was observed between males and females. "Long-named beverage that were made from domestic agricultural products" were regarded as the most healthful and ranked highest at 4.01. A significant difference between males and females was also observed. Long-naming influences a customer's purchasing tendency. In particular, women were more influenced by a sense of wellbeing when they purchase, because they are more interested in losing weight and being healthy.

The study results regarding the ingredient differences, sensory characteristics, purchasing type, usage and improvement direction for home-made traditional doenjang and factory produced commercial doenjang are as follows. The L-value indicates that home-made traditional doenjang has a higher value in average than the factory produce done, and the a-value indicates the opposite. Home-made traditional doenjang had higher water content than commercial doenjang ; however the pH values of commercial doenjang and home-made were 5.34 and 5.32 respectively, which was very similar. Factory produced commercial doenjang showed higher protein content than the home-made traditional doenjang. Regarding the correlation between ingredients, there was a significantly negative relationship between the L-value and a-value but a significantly positive relationship between the L-value and b-value. There were no significant relationship with water content, pH and protein content. For the color and taste, which are the sensory characteristics, commercial doenjang showed higher value than the traditional doenjang, but for smell, the values were similar. Regarding grittiness, the factory produced commercial doenjang had bigger particles than the traditional doenjang. Preference was a bit higher in the traditional doenjang. Of the 380 study subjects, most were from 40 to 49 years old (65.5%), and the most family type were nuclear families which was a total of 400 people (69%). Moreover, the most residential type was apartment which was 355people (61.2%), and for the monthly income, more than 2,510,000won was 48.3%. For the educational background, college education was 304 people (52.4%), and high school education was 199 people, 34.3%. In the usage, most of the people eat doenjang more than once a week, and usually their parents make the doenjang. People used both commercial doenjang and home-made traditional doenjang >home-made only >factory produced commercial doenjang only in that order. The reasons for using the home-made traditional doenjang aredelicate taste and flavor>more nutritious> anti-cancer ingredients in that order. The reason they use the factory produced commercial doenjang is because they don't know how to make it at home. The things that needed to be improved in the home-made traditional doenjang are bad smell> entire quality> flavor> color in order, indicating that studies for reducing bad smell are required. The things that needed to be improved in the factory produced commercial doenjang are taste & flavor> entire quality>bad smell> color in that order, indicating that people are more concern about it tasting like home-made than the smell. From the above results, we can see that better functional doenjang should be developed for family health and to increase the consumption of the doenjang, which has good functional psychological activities, also more various types of foods that use doenjang and scientific studies to reduce the home-made doenjang smell should be continuously studied. Moreover, studies on how to make the factory produced commercial doenjang taste more like traditional doenjang should be performed.

The elderly population in Korea is growing rapidly and their nutritional status is not acceptable. Data were collected from the self-administered questionnaire of 495 free living elderly, over 65years old, in Korea to asses the intake and consumption pattern of milk and dairy products. The questionnaire contains demographics, health related characteristics, and perception on milk, and consumption behaviors of milk and dairy products. Most of the elderly subjects understood that milk is good foods in terms of nutritive value and health. And 67% of the subjects satisfied with the sanitation status of milk on the markets. The kind of milk that majority of the subjects consumed was whole milk, and only 5.1% of them consumed low fat milk. Less than 20% of the subjects consumed milk everyday, living alone group consumed milk less frequently than living with others. It was found that the majority of the elderly subjects did not meet current recommendation for milk. Liquid and curd type yogurt were the major dairy products used among elderly, and the reasons were good taste and digestion. They believed that these kinds of dairy products help constipation and digestion problems. The price of milk was ranked for the first factor needed to be considered for milk and dairy products consumption in elderly korean.

The purpose of this study was to investigate the housewives’ consumption pattern and preference of the Korean rice cake asa substitute for meal.

The purpose of this stud was to investigate the degree of recognition as well as the consumption pattern of convenience food products, and related factors among 700 mixed Korean college students using written questionnaire. Students of Seoul region showed the significantly lowest rate of recognition at 36.7%. Results also showed that lifestyles have a significant effect on the degree of recognition of convenience foods. The consumption patterns of convenience foods goes as follows: used frequently-18.2%, once in awhile-73.9%, doesn't use-7.9%. The higher the recognition rate, the higher the consumption rate for convenience foods. When compared in terms of residence, students living at home used more refrigerated foods compared to students living outside of the home. Among the total students living outside of the home, students living on their own scored highest of convenience food consumption. In the case of female students living outside the home, respondents living alone and in dormitories scored the highest. Female students living in dormitories were mainly using refrigerated and canned foods, while those living alone consumed more kimbap and 'sa-bal-myun' in convenience stores. Korean college students mainly consumed frozen food, retort food, and kimbap in convenience stores. The college student that believes that 'You eat to satisfy hunger' significantly used more convenience food while those that marked 'maintain health' consumed the lowest showing a great difference between groups. Results showed that the lower the food habit score, the higher the usage score of convenience foods. The food habit score had a negative correlation with the usage of frozen foods, instant food, and convenience store food. When compared individually, packaged 'ramen' and 'sa-bal-myun' scored the highest points of usage. Frozen fried rice and pre-packaged rice scored the lowest points indicating Korean college students do not consider rice a convenience food. Convenience food consumed in convenience stores ranked the highest among places of consumption, compared to places like home or outdoors; showing that convenience foods were used by people with limited time constraints.

This study was undertaken to assess eating habits and food consumption pattern of 365 adolescent girls in Kwangju area. Subjects were divided into 3 groups based on relative body weight as obesity index. Anthropometric data showed that mean height and weight were 161.9±19.0cm and 53.3±7.2kg respectively which are similar to those in the Korean Standard Growth data. Mean BMI and relative body weight were 20.50 and 97.1%. Age of menarche in the subjects significantly influenced the obesity index. Food habit score in the underweight group was significantly lower than that in the normal group at α=0.2 level by multiple range test. Obesity was significantly associated with more frequent and irregular eating. It seems that students in the obese group were concerned on their body weight and tended to consume much vegetable. Obese group consumed more fruits, less butter and fruit juice compared to other groups. It might be suggested that more effective nutrition program might be developed and implemented to ensure good food habit of adolescent girls including obese as well as underweight group.

The aim of this study were to assess high school students' consumption pattern of Korean rice cakes and to analyze the preference of them by students' demographic backgrounds. Self completed questionnaires were collected from 672 high school students in Seoul area. A questionnaire consisted of three parts including demographic backgrounds, student's consumption pattern and preference of Korean rice cakes by type. Statistical data analysis was done using the SPSS/PC program for descriptive analysis, t-test and 2 test.

The research was conducted to investigate the children's consumption pattern and preference of Korean rice cake by analyzing the relation among their socio-demographic backgrounds. This study provides basic information for systematic development and wide spread of Korean rice cake as a traditonal Korean food. A self completed questionnaire survey of 639 elementary school students in Seoul was undertaken. A survey questionnaire consisted of two parts including demographic backgrounds, children's consumption pattern and preference of Korean rice cake. A likert scale of one to five was used to determine the childrem's preference of Korean rice cake. Statistical data analysis was done using the SPSS/PC program for descriptive analysis and 2 test. Approximately half of the participants were male (51.5%) and 5-degree year (50.7%) students. 77.2% of respondents were nuclear families. The results of eating frequency rate showed that 57.1% students had Korean rice cake once a month followed by once a week (18.8%), once per two months (12.2%) and once per six months (10.5%). The major reasons for having Korean rice cake were good taste (55.2%), healthy food (22.3), our traditional food (17.3%), and etc (2.2%) in order. Average children's preference score of 14 Korean rice cakes was 2.82±1.59 out of 5, with the highest score of 4.30 for Songpyun and the lowest score of 1.06 for Bukumi.

주부들의 채소 소비 형태를 조사한 결과는 다음과 같이 요약할 수 있다. 1. 조사대상자의 73.4%가 30, 40대로서 고졸이 57.6%를 차지하였고 서울거주자가 77.2%, 아파트에 거주하는 사람이 50.5%, 핵가족이 78.8%, 4~5인의 가족수를 가진 가정이 56%, 월 평균수입이 150~200만원 이하가 50%였으며 전업주부가 84.8%였다. 2. 채소의 구입비용은 일주일에 1~2만원, 구입빈도는 일주일에 2~3회, 신선한 채소는 주로 흙이 붙어 있는 손질되지 않은 상태를 구입하였다. 구입장소는 주로 시장의 채소가게와 농협을 포함한 슈퍼마켓이었고 백화점에서 채소를 구입하는 연령은 주로 30, 40대로 나타났다(p〈.05). 3. 채소구입시 연령, 교육수준, 수입에 따라 우선적 고려요인이 달랐으나, 모두 무공해에 비교적 관심이 많았으며, 수입이 적은 경우에 가격이 중요한 요인으로 나타났다. 4. 가족구성원 중 채소반찬을 가장 좋아하는 사람은 주부 자신이었으며 가장 싫어하는 사람은 자녀 특히 아들이었다. 5. 채소조리법 중 기본적으로 김치류가 가장 선호되었고 자주 이용되지 않는 조리법은 샐러드로 나타났다. 6. 응답자의 54.3%가 채소반찬의 구입경험이 있었으며 별미로 먹기 위한 이유가 가장 많았다. 서울 거주자가 자주 구입하였으며(p〈.01) 저소득층에서는 편리함 때문에(p〈.05), 가족수가 적을수록 핵가족일수록 소량 필요해서(p〈.01), 확대가족은 별미로 먹어보려고 (p〈.05) 채소 반찬을 구입하였다. 판매되는 채소반찬을 구입하지 않는 이유는 비위생적인 요인이 가장 컸고, 첨가물 함유 가능성 때문에 채소반찬을 구입하지 않는 경우는 서울보다 지방거주자가 더 많았으며(p〈.05) 교육수준에 관계없이 첨가물의 함유가능성을 염려하였다. 7. 김치의 구입경험이 있는 사람은 27.2%였으며 구입이유는 시간부족이 가장 많았다. 서울에 거주할수록 (p〈.05), 직업이 있는 주부일수록(p〈.05) 편리함 때문에 김치를 구입하였고 수입이 낮은 가정은 소량 필요해서 구입하였다(p〈.01). 김치를 구입하지 않는 이유로는 김치를 사먹는 것이 좋지 않게 생각되어서가 가장 많았다. 지방에 거주할수록(p〈.01) 김치구입 자체를 좋지않게 여겼고(연립주택에 거주하는 사람은 비위생적 요인으로 김치를 구입하지 않았고(p〈.05)), 학력이 높을수록 첨가물 함유 가능성 때문에 김치를 구입하지 않았으며(p〈.05), 시간적 여유가 비교적 있는 part time 일을 하는 주부는 맛이 없어서 김치를 구입하지 않는다고 하였다. 8. 채소에 함유된 영양소 3가지는 비타민, 무기질 및 섬유소로 응답하였고 응답자의 83.2%는 채소에는 cholesterol이 함유되어 있지 않으므로 채식이 건강에 좋다고 하였다. 또한 질병치료에 유효한 채소는 당근 등 42가지, 질병을 유발시키는 채소는 고사리 등 10종을 지적하였으며 이들은 과학적 증명이 가능하거나 민간요법으로 전해지고 있는 내용이다. 이상과 같이 덕성여자대학교 평생교육원에 다니는 주부의 채소 소비 형태에 대하여 살펴보았는데 가공된 채소반찬과 김치의 구입은 현재까지 일반화되지 않고 있음을 알 수 있으나 김치보다 채소반찬의 구입경험이 더 많은 것으로 나타났다. 본 논문은 덕성여자대학교 평생교육원에 다니는 주부를 대상으로 하였으나 앞으로 다양한 계층의 주부를 대상으로 하여 폭 넓은 채소소비에 관련된 연구가 이루어져야 한다고 사료된다.

본 연구는 한국과 일본에서 매년 실시하고 있는 국민영양조사 결과를(일본은 1950년-1988년, 한국은 1969-1988년) 바탕으로 양국의 식생활 변화 양상을 비교하여 미래의 한국 식생활의 지침이 되고자 하였으며 그 결과는 다음과 같다. 식품군별 섭취량에서 섭취총량은 일본은 1973년을 기점으로 감소하였으며 한국은 증가와 감소를 되풀이하며 전반적으로 증가 경향을 나타내었다. 한·일 모두 식물성 식품의 섭취는 감소하고 있고 동물성 식품의 섭취는 증가하고 있는데 1988년에는 동물성 식품 섭취 비율이 5% 정도 일본이 한국에 비해 많았다. 식물성 식품은 곡류의 경우 양국 모두 감소 경향을 보였고 1988년의 경우 한국이 일본에 비해 70g 정도 많이 섭취하였다. 한국은 감자류, 두류, 과실류는 1980년 이후 증가 경향이나 군별 섭취총량은 일본에 비해 낮은 수준이었다. 일본은 과일, 야채류의 섭취가 감소 경향이고 두류, 감자류는 변화가 거의 없으며 안정된 추세를 보였다. 동물성식품의 경우 일본은 우유 및 유제품, 육류는 증가 경향을 나타내었고 어패류, 난류는 1975년 이후 거의 평형 상태를 유지하였으며 한국은 육류, 어패류의 섭취 증가가 뚜렷하였다. 1970년 이후 양국의 신장, 체중의 연차추이를 보면, 1970년에서 1980년까지 한국인의 신장 증가가 현저하였으며(1970년 ; 150.3cm, 1980년 ; 160.2cm), 체중도 이와 유사한 경향을 나타냈다.
