Most of current shopping malls do not satisfy everyone because they present arrangements of goods and suggestions uniformly and comprehensively according to the thinking of their managers. On the other hand not the standard of selection but the comparison of price plays a decisive role of the purchase of goods as similar form each other. When classifying into groups according to generations, gender, income, job, hobby, etc. the propensity of purchase is showed differently and the interest and real purchasing power of the individual is different in shopping malls. It also will maximize the purchasing power of customers to make and implement the sales strategy more quickly as the basis of fashion and season of environmental factors and natural calamity of environmental variable according to the economic principle. This paper concentrates on the design and implementation of intelligent shopping mall that is added the sales strategy according to environmental variable and can not only analysis, update and classify the propensity of purchase continuously but also construct optimal goods automatically.

This study analyzes the current educational curricula in the field of Clothing and Textiles in order to develop appropriate educational methods and courses. We reviewed the curricula offered by 58 Clothing and Textiles Departments at four-year universities in Korea. We analyzed the educational content of each curriculum by dividing all of the courses offered into eight categories. The analysis was based on the information posted on the universities' Internet websites, and the analysis was performed by using descriptive statistics. The results of this study are as follows: First, the educational courses of the Clothing and Textiles Departments are composed of, 36.2% design, 20.4% production, and 14.5% textile categories. In comparison with the results of a similar study conducted in 1999, emphases on the design, distribution, and marketing categories have increased, while the emphases on the production, apparel material, basic knowledge, and consumption science categories have decreased. Second, in the case of the apparel material category, basic knowledge of materials constituted 18.5%, the largest part of the category. The average number of units offered in the area of apparel materials by the 58 Departments was 17 units per year. The curricula were found to vary by regions of the country. The universities located in the Chungcheong region offer more textile material courses, but the universities in the Capital region offer fewer textile material courses than other regions. Departments that are affiliated with universities that emphasize Art and Design have more courses on basic knowledge, dyeing and finishing, and fabric design than other universities.

Purpose: Following tooth extraction, alveolar ridge preservation (ARP) can maintain the dimensions of ridge height and width. Although previous studies have demonstrated the effects of ARP, few if any studies have investigated the compressive force applied during grafting. The aim of this study was to determine the effects of different compressive forces on the graft materials during ARP. Methods: After tooth extraction, sockets were filled with deproteinized bovine bone mineral with 10% porcine collagen and covered by a resorbable collagen membrane in a double-layered fashion. The graft materials were compressed using a force of 5 N in the test group (n=12) and a force of 30 N in the control group (n=12). A hidden X suture was performed to secure the graft without primary closure. Cone-beam computed tomography (CBCT) was performed immediately after grafting and 4 months later, just before implant surgery. Tissue samples were retrieved using a trephine bur from the grafted sites during implant surgery for histologic and histomorphometric evaluations. Periotest values (PTVs) were measured to assess the initial stability of the dental implants. Results: Four patients dropped out from the control group and 20 patients finished the study. Both groups healed without any complications. The CBCT measurements showed that the ridge volume was comparably preserved vertically and horizontally in both groups (P>0.05). Histomorphometric analysis demonstrated that the ratio of new bone formation was significantly greater in the test group (P<0.05). The PTVs showed no significant differences between the 2 groups (P>0.05). Conclusions: The application of a greater compressive force on biomaterials during ARP significantly enhanced new bone formation while preserving the horizontal and vertical dimensions of the alveolar ridge. Further studies are required to identity the optimal compressive force for ARP.

This study aims to explore the diverse characteristics of obese groups of Korean males in their 20's to 40's. A total of 201 males who each had a BMI (Body Mass Index) of 23 or over were recruited through a convenient sampling. Samples were categorized into groups of overweight, slightly obese, and severely obese, and submitted for data analysis. Results are summarized as follows. First, in terms of demographic characteristics, slightly and severely obese males were older than overweight males. There were also group differences in marital status and household income. Second, slightly and severely obese groups demonstrated a higher perception of obesity and a lower perception of health than did the overweight group. Third, there were no group differences in body satisfaction, socio-cultural attitudes toward appearance, and self-esteem. Based on these results, we concluded that overweight, slightly obese, and severely obese groups were distinguishable from each other in terms of their demographic characteristics, whereas the slightly obese group and the severely obese group were not different in terms of perception of obesity, perception of health, weight control behaviors, body satisfaction, body image, socio-cultural attitudes toward appearance, and self-esteem. These findings may reflect that people may not become increasingly sensitive to socio-psychological stimulations as they gain more weight if they have exceeded a certain level of obesity. This observation provides meaningful implications for the differences among obesity groups given the lack of prior research focusing on this issue.

In this study, 3D measurement data of 70 to 85 years old men were analyzed to investigate the body shape characteristics. and the type of the whole body of older men. Through this study, we aimed to provide basic data necessary for making good clothes for elderly men. We analyzed the body shape of elderly males using Korea 's 2015 elderly anthropometric data by SPSS Ver. 24.0. The body shape of older males was classified into four types: 'thin & long inverted triangle with thick legs', 'thick & short inverted triangle with bird legs', 'thick & long triangle with thick legs', 'thick & short triangle with thick legs'. As the age increases, the shoulders are sagging, the progressive reduction of the spine leads to a decrease in height, and the backbone refraction causes a decrease in the anterior center length and an increase in the back length. In addition, as the age increases, the chest circumference decreases and the abdomen and waist circumference increase. Considering these physical changes, it is necessary to set the length of the garment to 2-3cm shorter in the case of the aged layer. Waist and abdomen area are increased, it is considered that it will be necessary to add more margin of 2cm than general silver clothing when setting the margin amount. When setting the length of the upper body, it is considered that the front center length should be reduced and the back length should be increased to keep the bottom level. In this study, only the elderly males aged 70-85 years were included in the analysis of the whole body type. It is significant that the studies so far have been extended to those older than 70 years. Future research will need to be applied to the development of silver clothing through comparison of older men 's body shape in their 60s and 70s.

The purpose of this study was to develop a caregiver's uniform that is appropriate for nursing and to improve movement adaptability as well as having a pleasing appearance. Based on the results of preliminary study, I investigated the inconvenience and problems with the existing uniforms and made a sample uniform taking into consideration the design, the material, and the pattern. We carried out a sensory assessment and quantitative assessment in order to compare the sample uniform with existing uniforms. Following are the results of this research. The top is a short-sleeved blouse with a round neckline having no collar and with armpit gussets. The armpit gussets are semicircles and the inverted pleats in the back are an improvement designed for activity. The pants are long reaching to the ankles with elastic in the waist so that the waist measurement may be adjusted. The length of the pants can be adjusted with strings and the pants have a funnel-shaped pocket for adjustment of length. We used a mix of polyurethane and polyester for the outer cloth of the uniform in order to improve activity function and used $Coolever^{TM}$, the sanitary textile that absorbs moisture well and dries in a short time, for gussets in the armpits, which is the heavy sweat area. The appearance assessment and movement adaptability assessment were performed with 5 subjects and 9 experts. For the results of the assessment, the sample uniform was appraised to be better than the existing uniforms in every item of an appearance comparison assessment except for the neckline assessment by the experts. As for the assessment of movement appropriateness and wearing assessment, the same subjects were used for analysis. As the results of the assessment, the sample uniform was rated higher than the existing uniforms in movement adaptability and pleasing appearance.

This study set out to compare and analyze the spaces in the images and sets of the representative movies that led the new heyday of Korean film since 1997 and examine the characteristics of contemporary Korean modernism in the movies, thus building an academic foundation for future exchanges between contemporary Korean architecture and contemporary Korean cinema. As for methodologies, the study first examined the film theories on how to utilize spaces projected onto moving images. Secondly, the study made an overall comparison of the characteristics of spaces in the representative movies of contemporary Korean cinema since 1997. Finally, the study compared and analyzed them with the intrinsic characteristics of modernism architecture space. The research findings were as follows: first, the representative movies of contemporary Korean cinema since 1997 either had a backdrop of everyday modernism space in the 1970s and 1980s or created a new space of late or post modernism in them that escaped from daily life for the mise-en-$Sc\grave{e}ne$ composition. Secondly, the contemporary Korean cinemas used the unornamented modernism architecture in Korea as the props of revealing the personalities and emotional aspects of the characters in a prominent fashion. Thirdly, they also used communication between internal and external space and spatial severance via the facade window in modernism architecture as important devices for narration organization. Finally, they selected the camera positions by applying the principle of open space, which allows for the expansion, reduction, and distinction of space according to functions, and thus established a methodology to create a space fit for the personalities of characters and stories.

This study sought to measure the absorption of commercially available urinary incontinence panty by applying a method of measuring the maximum saline amount of adult diapers in an international standard. The subject was 15 products from 3 brands on the market, and the SPSS 27.0 program was used for analysis. As a result of measuring the maximum absorption of commercial incontinence panty, it was found that the maximum absorption of product B was the highest and the maximum absorption of product C was the lowest. Even though the product was marked with the same absorption amount, it showed differences in the same product of the same brand, and it also showed differences depending on the brand. The reflux amount of the injected physiological saline and the urinary incontinence panty showed a positive (+) correlation, and as the amount of the injected physiological saline increased, the reflux amount of the urinary incontinence panty increased. It was analyzed that the time when the leakage begins and the amount of leakage have a negative (-) correlation. In future research, it is believed that the development of functional pads that can increase absorption and reduce reflux and leakage should be carried out.
