The objectives of this study were to classify the types of elderly households and to compare the characteristics of their dietary lifestyle. Panel data surveyed by Korea Rural Economic Institute (KREI) for Food Purchase Attitudes over three years (2019 - 2021) were utilized for the analysis. Through a factor analysis, five common factors were extracted out of 19 basic variables related to dietary style, which indicate two kinds of consumer competency index (safe diet, traditional diet) and three kinds of purchase frequency (healthy food, meat & fish, fresh seafood). Applying the cluster analysis method, by using socioeconomic variables along the five common factors, elderly households aged 60 or older were grouped into four types. As a result, Type 1 elderly households accounted for 50.8%, Type 2 for 16.2%, Type 3 for 27.8%, and Type 4 for 5.2% out of all 870 elderly households. Type 1 is characterized as a low-income vulnerable class with a poor diet, Type 2 as a middle-income class with a healthy food-oriented diet, whereas Type 3 was classified as a middle-income class with a meat-oriented diet, and Type 4 as a high-income class with diverse dietary culture. It is necessary to expand the agri-food voucher pilot project to the entire country and also increase the monthly subsidy for the Type 1 elderly households. Implementing community kitchen projects for elderly single-person households, promoting senior internships by providing incentives to companies that employ retirees, the provision of education by local governments on a safe and balanced diet for Types 2 and 3, and the promotion of an elderly-friendly social environment are also recommended.

With the greater importance of lifestyle shops and experience marketing, research is needed for the effective experience marketing of lifestyle shops by fashion product type. This study establishes effective and differentiated experience marketing strategies for fashion lifestyle shops by examining the effect of the experience marketing satisfaction with lifestyle shops on purchase intention and loyalty. This study categorizes lifestyle shops by fashion product types into a suit-oriented lifestyle shop, a casual/leisure/sportswear-oriented lifestyle shop and a home fashion lifestyle shop, Then a survey was conducted on participants who had visited lifestyle shop. As an analysis method, factor analysis, reliability analysis and regression analysis were conducted. In this study, we identified the experience marketing factors of fashion lifestyle shops. This study found that the satisfaction from experience marketing factors of fashion lifestyle shops by fashion product types affected purchase intention and loyalty differently. Considering the results of this study, it will be able to increase not only purchase intention and loyalty but also brand sustainability by establishing, applying, and executing a differentiated strategy considering the detailed factors of experience marketing for each fashion product type when planning and operating a fashion lifestyle shop. Through this study, effective marketing of fashion lifestyle shops by fashion product type will be implemented.

This study was carried out on 132 obese women who satisfied both of the conditions for the obesity: over 1.6 in Rohrer index and over 90cm in bust girth. The purpose of the study was to classify the body types of the obese women and find out their respective characteristics. The characteristics of the body shape were as follows. The one was that the height of the front waist was higher than that of the back waist. The other was that the depth of the front abdomen was high, which implies the protruding of the abdominal region. Five factors were extracted as the result of the factor analysis. Body types were classified 4 types(type 1 : long upper torso, type 2 : obese torso, type 3 : short and less upper torso, type 4 : obese arms and legs) according to the cluster analysis.

This study was a cross-sectional reaserch that analyzed the effect of emotional expression type on happiness level with structured questionnaires. A total of 186 participants in the study were in their 20s to 60s. Data collection was received from those who voluntarily agreed to the study from September 1 to 15, 2021. The collected data were frequency analysis, t-test, and regression analysis with spss 18.0. As a result of the analysis, it was found that people who perform superficial acts disguised as emotions were less satisfied with their current life (t=-10.482, p<0.01). People who do inner behavior showed high levels of happiness. These results suggest the following: It can be seen that in order to improve effective happiness, it is required to actively and truthfully act in a physical environment.

Fitness of clothes becomes a major concern in apparel industry. But high-school boys had difficulties to buy ready-made clothes of good fit. To solve this problem, it is necessary to classify boys' upper body into several kinds of somatotypes. The purpose of this study was to classify upper body types of high school boys based on the analysis of their upper body types. The subjects for anthropometric measurement were 99 high school boys of 16 to 18 year-old. The result of factor analysis indicated that 5 factors were extracted from anthropometric measurements through analysis and those factors comprise 68.44% of total variance. 3 clusters were categorized using 5 factor scores by cluster analysis. Type 1 was taller than other types and was bending somatotype. Type 2 was straight somatotype and had average size. Type 3 was characterized by short and small figure and had bending somatotype.

The purpose of this study was to provide basic information for women's women's head type for mil-inary. The subjects were 141 college women aged from 19∼23. Data were collected from the real anthropometric measurements and 4 index. Correlation coefficientss, factor analysis, cluster analysis and analysis of variance in SAS package. The results were as follows : 4 factors were extracted from 20 anthrometric measurements and in index data, which explain 60.0% of variance. The subjectss were classified into 4 clusters by 11 measurement and 4 index data. Each charicteristics of cluster by the measurements was flat, big, thick, small types in women's head. Each charicteristics of cluster by the index data was mostly flat in head thickness and wide, midium, narrow, very wide type in face.

This study has been focused on the development of a high speed feeding type three-dimensional bending machine. It is designed for manufacture of copper pipe for heat exchangers. For the purpose of design of the machine, analysis of bending process, structural analysis and reliability evaluation of the machine by a laser interferometer are carried out. The analysis is carried out by FEM simulation using commercial softwares, DEFORM, MARC and CATIA V5. In addition, the machine has attained high accuracy and repeatability. In order to improve the accuracy of this machine, the maximum speed, positioning accuracy and repeatability of feed are measured by the laser interferometer. The final results of analysis are applied to the design of a high speed feeding type three-dimensional bending machine and the machine is successfully developed.

In this study, we analyzed and experimented micro-strip line inductors and capacitors for a SAW duplexer, an important devise for mobile communication. For SAW duplexers, micro-strip line lumped elements must have small impedance values, below several tens of nH or several tens of pF, and a small area pattern. In this study, we performed theoretical analysis of flat line type, meander line type, and spiral line type inductors and interdigital capacitors on a LiTaO$_3$ Piezo-crystal. We proposed a measurement method to evaluate small values of lumped elements accurately with network analyzer. In experiments, we confirmed validity of the theoretical analysis method through fabrication and characterization of micro-strip line lumped elements. The analysis method in this paper can be applied to SAW duplexers well as other microwave devices.

In this study, we examined the feasibility of considering the transverse edge effect of flat type linear induction motor as 2D finite element analysis (FEA) by changing the resistivity of secondary conductor. For this purpose, the 3D FEA analysis results were compared with the 2D FEA analysis results with the change of the resistivity of the secondary conductors. As a result, simply changing the resistivity could not accurately account for the transverse edge effect of LIM because of leakage components that could not be considered by 2D FEA.
