The 'Joongsancheung(JSC)', a unique term for the middle class in Korea, is defined as a stratum sharing common lifestyles and a certain level of life chances. It involves non-economic factors such as life chance, educational attainment, occupational groups as well as economic factor. Such objective measures as the occupational status of the main breadwinner, family income, and the educational level of respondent, and subjective measures of class identification are used for the operational definition of the JSC. Data from a national survey of 1,515 respondents is analyzed to investigate the change of the JSC in size and the major determinants of class identification. The results show that while there is no strong evidence of any significant change of the JSC by the objective measures during the recent decade, there seems to be a slight decrease in the subjective class identification. In addition, binary logistical regression analysis reveals that self-identification of JSC is heavily influenced by house ownership, along with subjective evaluation of one's own income and property ownership. This study demonstrates that the apparent class polarization in Korean society reflects not so much objective conditions but subjective perception of respondent of his or her circumstance. It is suggested that problems of housing and relative derivation people have as regards income and property should be resolved to alleviate such class polarization in Korean society.

Farmers' perception on actual raising conditions and breeding improvement for Hanwoo were surveyed and analyzed in order to utilize such data as basic resources for further development of courses of Hanwoo improvement and instructions on raising techniques. The survey was held based on Hanwoo farmers in Gyeongbuk region and the results for the analysis were as follow. Candidate cattle for breeding was selected in consideration of 'appearance, body shape, and pedigree-registration' (39.0%) and 'artificial insemination' (38.6%) was the most frequently used breeding method for the breeding cattle. 'Body length' was revealed to be the most considered factor while purchasing fattening calves and the castration for the fattening calves were mostly performed when '6~7 months after the birth'. The farmers also responded that they 'try to comply with over 80% of items specified in program for production of high quality beef' in order to produce high quality beef. However, the farmers believed that '12 months after the birth' was the most economic market month. Although the results differed by each items surveyed, majority of those results showed statistically significant differences with significance level of 0.05 upon the surveyees' general characteristics and demographic factors including level of education, age, occupation, and family man power. Most surveyees responded 'around 30% of shipping heads' (22.1%) for the prevalence of beef graded better than 1++ grade when shipping, however, no significant differences in between general characteristics of surveyees were observed.

Objectives: This study analyzed Japanese consumers on their sauce consumption, and assessed the relationship between consumer innovativeness and consumption behavior for new sauce products. Methods: The survey was completed by local consumers visiting Korean restaurants in Osaka, Japan, in September 2018. The demographic characteristics, consumption of sauce, consumer innovativeness, and factors of theory of planned behavior were evaluated. Totally, 150 collected data were analyzed using the IBM SPSS Statistics 25.0 Program (IBM SPSS INC, Armonk, NY, USA). Results: Results of the survey indicate that Japanese consumers purchase a sauce by considering the taste and food utilization. Sauce purchases were maximum at mega markets and supermarkets. The consumer innovativeness for Japanese consumers was based on 3 factors: 'Purchasing adventurous products (3.51 ± 0.96)', 'Active information seeking (4.36 ± 1.11)', and 'Interactive information seeking (4.33 ± 1.02)', where the tendency of 'Active information seeking' was the highest innovativeness factor. Furthermore, higher values of perceived behavior control (4.68 ± 1.21), attitude (4.66 ± 1.41) and subjective norm (4.39 ± 1.28) were revealed, when assessing for theory of planned behavior factors. Correlating the variables of consumer innovation and factors of planning behavior theory, 'Active information seeking' is a positive attribute for attitude (p<0.016), subjective norm (p<0.001), and perceived behavior control (p<0.002). These 3 factors also had significantly positive effects on purchase intention for new sauce product (p<0.000, p<0.000, and p<0.002, respectively). Attitude was determined to be another very influential variable for purchase intention of a new sauce product (B=0.484, t=6.881). Conclusions: The results of this study determine the consumption patterns of sauce for the Japanese consumer, and the relationship between consumer innovativeness and consumption behavior for Korean traditional sauces. We believe the data generated from this study will help determine a marketing strategy to enter the Japanese market.

PURPOSE: The purpose of this study was to explore dental hygiene treatment fear and anxiety in dental patients. METHODS: The sample consisted of 466 dental patients who had received the dental hygiene treatment at 8 Dental Hospitals and Clinics in Daegu city between March and August 2006 studied. Dental hygienists recruited a questionnaire, which includes generalized anxiety sub-scale(4 items), specific fear sub-scale(5 items), distrust sub-scale(5 items), and catastrophic anxiety sub-scale(4 items). Minimum score is 1, and maximum score is 5. The research was designed to be a cross-sectional measured study. SAS statistical software was used for the analysis. The characteristics of the study sample were described by mean and standard deviation(SD) for continuous variables and by frequency and percentage for categorical variables. The Student's t-test and analysis of variance(ANOVA) were used to compare fear and anxiety score in demographic variables. A Pearson's correlation analysis was conducted for relationship among values of fear and anxiety for dental hygiene. Multiple regression analysis was performed to determine the factors associated with fear and anxiety related with dental hygiene. RESULTS: A total of 466 dental patients were analyzed, their average age${\pm}$SD was $37.7{\pm}12.9$ years(range: 15-79 yr). The mean value for dental hygiene fear and anxiety was 2.70(generalized anxiety 2.65, specific fear 2.93, distrust anxiety 2.72, and catastrophic anxiety 2.42, respectively). There was a statistically significant difference in gender(p<0.05), 2.81 for women was higher than 2.55 for men(p=.0000). The older we are, the higher fear and anxiety for dental hygiene treatment were. that is, under age of 20 years 2.49, 20 years 2.59, 30 years 2.69, 40 years 2.77, 50 years 2.88, 60 years 2.69, and over age of 70 2.45, respectively(p=.0321). Factors related to dental hygiene treatment fear and anxiety by multiple regressions were gender(${\square}$=0.18, p=0.0001), age(${\square}$=.07, p=.0058), and the time when visits dentist recently(${\square}$=.07, p=.0058). CONCLUSIONS: In conclusion, gender, age and the time when visits dentist recently were significantly associated with dental hygiene treatment fear and anxiety. We recommend that further research should investigate a dental hygiene treatment fear and anxiety by using more follow-up study.

The purpose of this study is to examine whether any correlation exists between the dental health capacity and preferred foods of Korean senior citizens over the age of 65 years. The 5th Korean National Health and Nutrition Survey were used. Tissue health index (T-health), Sound teeth (ST), Functioning teeth index (FS-T), Present teeth (PT), and Missing teeth (MT) were used as variables to assess the dental health capacity of the elderly. Preferred foods of the elderly included 63 foods that were categorized as cereals, pulses and roots, meat and poultry, fish, vegetables, sea algae, fruits, milk and dairy products, cream and sugar, and other foods. For data analysis, the weighted average was taken into consideration to generate planning files, and then complex sample analysis were conducted. For statistical analysis, frequency analysis, t-test, one-way ANOVA, and compound specimen linear regression analysis were conducted. T-health score was significantly high in the group with high preference for cereals, fruits, and other foods. In terms of age and economic status, 65~69 years, 70~74 years, and mid to low range in the income ranges scored high in T-health. ST score was significant in the group that preferred cereals, other foods; the corresponding demographic profiles represent 65~69 years, 70~74 years, and the mid-range income communities. FS-T was significant in relation with a preference for fruits, creams and sugars, other foods; the scores were also high for 65~69 years, 70~74 years, and mid-low to low income groups. PT and MT were significant in the group that preferred cereals and fruits; the same applied for 65~69 years, 70~74 years, and mid-low to low income individuals (p<0.05). Food preferences seemed to vary depending on the dental health state of the elderly, and the dental health state of the elderly may act as a risk factor for nutritional imbalance.
