ABSTRACT
Background In general, the elderly people experience a dramatic change in body type due to degradation in motor nerves, weakening muscles and skeletons, and changes in hormones as well. The back is bent with the pressure imposed on the spine with the head bent forward as the thoracic and the cervical vertebras are making sharper curves. The knees are bent as well due to deformation of the lower limbs, leading to changes in overall side posture. Against this backdrop, this study, unlike precedent ones that relied mainly on visual judgments, aims to identify changes in lateral body type based on the lateral angles of the elderly males using the three-dimensional image data.
Methods This study has selected the elderly males aged 70 to 85 years who were surveyed in the 3D human body type measurement research project in 2014 as its subjects, and made measured the angles of 448 subjects who were scanned in 'straight posture'. A factor analysis has been conducted using 42 angle items to identify the characteristics of the lateral body type and to extract of the factors that comprise the lateral body type. In order to classify the lateral body types into several categories, the K-average cluster analysis has been performed using the six factors extracted through the factor analysis that are used to determine the lateral body type.
Result The six factors that determine the lateral body type of the elderly have been found to be knee bending, spinal bending, the upper body’s incline, pelvic lifting, shoulder form, and position of abdominal protrusion. According to the results of conducting cluster analysis on lateral body type factors, lateral body type 1 is the ‘bending forward type with surging front high shoulder and bending knees (10.5%)’, type 2 is the ‘normal type with ending back shoulder (23.2%)’, type 3 is the ‘Sway back type with spinal bending and tilting shoulder (14.1%)’, type 4 is the ‘lean back type with bending back shoulder (11.2%)’, type 5 is the ‘Sway back type with surging front high shoulder and spinal bending (19.4%)’, and lastly, type 6 is the ‘bend forward type with surging front (21.7%)’.
Conclusion This study is different from the previous body type classification research because it forms the whole body shape by analyzing the side angle of the body three dimensionally.

ABSTRACT
Background Before 1980s, Korean jewelry industry used gold and silver as the main ingredient of jewelry and prioritized spot and material value of jewelry as the wealth. Such social perception gradually changed in 1980s through business expansion of jewelry shops and marketing promotion. Such change was brought by domestic business condition extended by economic growth. urthermore, in early 1980s, color television became popular in South Korea and various beautiful colors captivated consumers. As a result, jewelry in harmony with color and design became necessary. In addition, Asian Game in 1986, Iksan Jewelry Business Valley establishment in 1987, Olympic in 1988, liberalization of jewelry import, change from license system to report system for business foundation, and liberalization of overseas travel globalized eye of consumers. Such social environment change largely vitalized domestic jewelry market and domestic jewelry market expanded to include not only jewelry but also accessories. As boundary of accessories and jewelry was unclear, jewelry market broke away from handmade measures which is limited to small amount of type and production and entered casting generation which allows various kinds and mass production. However, although many years have passed since the introduction of such casting system, there is no clear data or standard for optimal casting methods. Also, there has been no research on supplementing method for various defects during casting and supplementing method is only passed by oral tradition or experience of technicians.
Methods This study aims to organize various defects frequently occurred during casting, discover causes of such defects, and suggest supplementing methods for such defects. Furthermore, this study organized general example and form for casting and analyzed easily accessible environment for high-quality casting result. The study also conducted research on type of defect and supplement method for such defects through field experience. For alloy jewelry casting defect, the study took a picture of defect when casting failed. Then, the study attached the picture and solved the cause of defect since product failed on casting has unique pattern. After solving the cause, the study compared the pictures of defect picture and result picture and organized corresponding casual relationship. The study also created data on optimized casting method based on survey conducted on people involved in jewelry industry at field. Through the survey on the most frequent answer and averaged content, the study covered stable casting method with low failure rate. The study also referred to the fact that different casting data is used based on thickness of the product group.
Result Following is the defect type, supplement method for major defect, and recommendation obtained from this study. First, among the causes of major defect on casting, defects occurred during wax injection process were identified. Defect during wax injection, defect due to was pressure and inadequate rubber mold bonding, defect due to insufficient review, supplement measures after wax injection, defect due to careless wax tree glueing, and defect due to unskilled wax stream bonding were found through test. The study researched on supplement method and suggested recommendation for solving such defects. Second, defects occurred during investment mold process were identified. The defect due to mixing ratio difference between gypsum and water, defect due to unskilled vacuum dewaxing during investment mold, and defect due to gypsum setting time control were identified through test. The study researched on supplement method and suggested recommendation for solving such defects. Third, defects occurring due to casting temperature control failure were identified. The defect due to unskilled temperature control for dewaxing(burning) at electric furnace, squeeze casting(melting pot) temperature defect due to unskilled control of oxygen/gas torch, differentiation based on thickness and width of cast(object) were identified through test. The study researched on supplement method and suggested recommendation for solving such defects.
Conclusion The research shows that the development of a more systematic optimized casting technique and production of successful products will contribute to the virtuous cycle of the precious metal related industry by taking advantage of the loss rate and time saving effect considering the high precious metal characteristics.

ABSTRACT
Background In Korea, as of 2018, the elderly population over 65 years old account for about 14.37% of the total population. With this rapid pace of entry into the aging society, interest in health promotion is increasing. The people who use the clinic are expanding from child to old age. Therefore, not only both sides but also oriental medical services are also emphasized and emphasized. When using oriental medicine, there are inconveniences such as waiting, medical treatment, pharmaceuticals, etc., compared to both medical services.
Methods The scope of the study is the entire process by which a user receives a medical consultation. In the first stage of the service design methodology using the double diamond methodology, and in the discovery phase, the user's discomfort and needs are derived through a survey. In the second stage of the definition phase, we plan to improve the medical service design of the Korean traditional medicine clinic based on the data analyzed in detail.
Result As a result of the survey in this study, most users were not satisfied. Among them, spontaneity, mutuality, and spontaneity at the stage of medical treatment were found to be the weakest at the reception stage.
Conclusion In contrast to the fact that the domestic medical service design is activated, the medical service design of the users using the oriental clinic is not satisfactory, and it seems that the medical service design of the oriental clinic is needed more firmly. We expect that this study will be revitalized in future and become more reliable medical service.

ABSTRACT
In recent years, the increase in the number of single-person households has favored easy eating in the home. In particular, it is becoming more and more common for kimchi to be made at home, and thus the number of cases of purchasing packaged kimchi is increasing. Therefore, it is necessary to try to apply the Kimchi products to the package design by focusing on the visual expression factors. Therefore, this study aims to present the expression strategy by questioning the consumers' preferences about the expressive elements in Kimchi package design in Korea and empirically analyzing them.
Methods We surveyed the preference of kimchi brand package design for 400 consumers over 20 generations in Seoul Gyeonggi area and analyzed the preference difference of package design expression factors by manufacturer.
Result As a result of analyzing the preference of Kimchi package design by seven expression factors, it was found that brand name, brand logo, layout, and infographic were preferred by using pictures and letters. Pulmuone's preference was high in the slogan of illustration, corporate and consumer stance.
Conclusion It is meaningful to establish the expression strategy to grasp the consumer 's preference about the package design of Kimchi product. The questionnaire for the existing product does not reflect the characteristics of the seven expression strategies, so it is necessary to study in depth expression elements.

ABSTRACT
Background With 4th Industrial Revolution, AI (Artificial Intelligence) has emerged as a major industry. Among variety products that are developed using the AI technology, AI speaker is gaining attention as a major product and shows rapid growth in consumer IoT (Internet of Things) market. Unlike the rapid growth and attention in the market, consumer satisfaction of AI speaker is low. Low satisfaction level is the important factor to ultimately end the usage of AI speaker.
Methods In this study with the hope of securing continuous growth and the spread of the AI speaker, factors that would affect the user’s continuous usage of the AI speaker usage have been explored. To achieve research objectives, we looked at the impact of emotional attachment as an emotional source of emotional attachment as an emotional factor in user satisfaction theory and in prior research related to continuous use. It also confirmed that emotional attachment also mediated between user satisfaction and continued use.
Result The research result shows that satisfaction level does affect the usage continuity; furthermore, users’emotional factors are identified as important variables to allow users decision to use AI speakers continuously.
Conclusion This shows that AI speakers to have an ability to be customized to create unity with user’s personal space is as important as the development of AI speaker technology to increase the user’s satisfaction level and to increase the consumers’ usage continuity. Thus, by having AI speakers’ design to fit into user’s lifestyle, user’s emotional attachment toward the product will increase, ultimately increasing the continuity of the product usage.

JEWNR 63(0) 101-114, 2019 |
ABSTRACT
Background UXD 5-layer and 10-element proposed by Garrett is commonly cited, which shows the system process of user experience design. It indicates a conceptual model and provides general basis for user experience design.
Though “availability” is one of attributes that the success in user experience is made. However, positive experience cannot brought to the user only by virtue of availability. To emphasize the importance of the user satisfaction to the empirical design, it is advised to integrate theoretical elements of FLOW with those of UXD to formulate new UXD framework.
The model of Garrett pays attentions to the user experience, but there is obvious lack of basis that could affect user’s psychological state.
The research purpose is to explore the possibility that FLOW theory is integrated into the user experience design model through analysis on the development status of psychology and FLOW theory in the field of design. In addition, the basis is provided for user’s psychological design.
Based on 5-layer and 10-element proposed by Garrett, the research result of psychological input theory is analyzed to make up for the deficiency in existing UXD 5-layer and 10-element model and propose new experience design framework.
Methods Firstly, the development of UXD is investigated and UXD 5-layer and 10-elment is analyzed in the research to conclude advantages and disadvantages.
Secondly, the status of the application of psychology into design is studied to find out the basis of FLOW theory (Cskinszentmihalyi) for psychology aspect of UXD 5-layer and 10-element model proposed by Garrett.
Under the background of user experience design, 8 elements of FLOW theory are summarized as 9 elements and 4 stages of FLOW to associate these 9 elements with UXD 5-layer and 10-element model. Then, 9 elements of FLOW are rationally supplemented in all aspects of UXD 5-layer and 10-element model to form the new UXD design framework (FUXD) aimed at reaching the FLOW state.
Result FUXD framework, independently existing to realize user’s best experience and satisfaction, is the supplement of existing user experience element framework. According to the research result, it is necessary to take FLOW element as the design objective and integrate it with user experience element. New experience design framework is developed through analysis of user experience and FLOW element from the theoretical aspect in the research.
Conclusion New design framework emphasizing the optimal experience and satisfaction that is integrated with user experience element by taking FLOW element as design objective, which makes up for the deficiency in user satisfaction in the existing user experience element model.As abovementioned, FUXED framework proposed in the research indicates the new experience design framework based on the user’s psychology. It is the design framework escalating to the mental and psychological demands from functional needs. The existing user experience element model is improved to make up for the user’s psychological deficiency.
