The purpose of this study was to develop a customized wrist brace using 3D scanner and 3D printer. This study included in-depth interviews with people who had wrist pain and ever used wrist braces. The wrist brace has been designed and modeled by the CAD program after 3D scanning the wrist of subjects. Based on the results of the in-depth interviews on wrist brace users and design investigation in the market, a prototype of the wrist brace has been created. The wrist brace does not compress the hand and is easy to put on. In addition, it is adjustable to the wrist of users, allowing them to move his or her wrist without any restrictions. A computer-modeling program produced solid files for the design of the wrist brace after 3D scanning ten subjects' hands. It features a lattice-patterned surface, a velcro adjustment and trimming to smoothen the surface. PLA filaments were used to 3D print the wrist brace. As for the assessment, the wrist brace has been evaluated to be easy to put on and adjust to user's wrist. However, when it comes to appearance and comfortability, it was rated 3.0 or slightly above. This is because 3D printing materials are firm and not flexible compared to other materials such as neoprene or stretchable bands.

The purpose of this study was to compare the status of sanitation education and sanitation knowledge in school foodservice with commercial foodservice. The survey sample was institutional foodservice directors (n = 88) in A office of education and commercial foodservice directors (n = 81) in B foodservice industry. The questionnaire requested information about demographic information, situation of sanitation education, contents of sanitation education practice, importance of sanitation education, and sanitation knowledge. Data were analyzed using frequencies, means, chi-square test, and t-test. Over half (52.1%) of the respondents were institutional foodservice directors, 47.9% of the respondents were commercial foodservice directors. The majority of institutional foodservice directors were 25-29 years of age (38.6%), over 10 years of working experience (63.6%) and commercial foodservice directors were 25-29 years of age (53.1%), 5-10 years of working experience (35.0%). 66.3% of the respondents were educated food safety once a month, but 8.6% of commercial foodservices were never educated. The majority of the respondents used printing materials (73.3%) or lecture (74.8%). The importance level of institutional foodservice directors about sanitation education was significantly higher than commercial foodservice directors. The average score of institutional foodservice directors' sanitation knowledge was 87.05/100.00. The commercial foodservice directors' sanitation knowledge 67.74 was significantly lower than institutional foodservice directors (p < 0.05). Therefore, there should be a systematic education program designed for commercial foodservice directors.

Indigo is utilized in various industries including textile dyeing, cosmetics, printing and medicinal products and its reduced form, leuco-indigo, is mainly used in these process. Chemical reducing agent (sodium dithionite, sodium sulfide, etc.) is preferred to use for the formation of leucoindigo in industry. In traditional indigo fermentation process, microorganisms can participate in the reduction of indigo and thus it has been known to reduce environmental pollution and noxious byproducts. However, in fermentation method using microorganisms it is difficult to standardize large scale production process due to low yield and reproducibility. In this study, we attempted to develop the indigo reduction process using microbial flora which was isolated from naturally fermented indigo vat or deduced by metagenomic approach. From the results of library analyses of PCR-amplified 16S rRNA genes from the traditional indigo fermentation vat sample (metagenome), it was confirmed that Alkalibacteriums (71%) was distinctly dominant in population. Some strains were identified after confirming that they become pure culture in nutrient media modified slightly. Four strains were separated in this process and each strain showed obvious reducing ability toward indigo in dyeing test. It is expected that the analyzed results will provide important data for standardizing the natural fermentation of indigo and investigating the mechanism of indigo reduction.

Recognizing the importance of early childhood education, the government is preparing measures at the national level, including expanding the scope of free education for infants, linking early childhood education to elementary schools, unifying the system in charge of early childhood education, printing the cost of operating a full-time system for double-income couples, and policies for low-income infants. In Korea's childcare policy, the need for childcare has increased due to the increase of free double-income couples, the increase of nuclear families, and the increase of divorce rates. Despite the overall increase in the child care budget, Korea's child care policy shows many problems in its efficiency due to the burden of childcare facilities and childcare fees for caregivers. After looking into the theoretical contents of the free childcare policy and the corresponding child care support policy, we would like to consider ways to improve the free childcare policy.

This study was designed to figure out the changes in elderly women's foot size and shape by aging, to propose size specification for elderly women's shoes, and to produce regression equations using representative measurements items to estimate other measurements usually hard to get. Subjects were 118 women of 30-59 years and the 227 elderly women over 60 years. Martin's anthropometry was done on the right foot of each subject for 25 items. And 11 indirect measurement items were measured on both foot printing sole outline and picture in profile taken by digital camera. For statistical analysis on the anthropometric measurements by SPSS program, analysis of variance, post-hoc test(SNK-test), crosstabulation, multiple correlation analysis, regression analysis were performed. The results of the study are as follows. Firstly, it was found that the foot figures of elderly women over 60 years were smaller in girth and width than those of below 60 years. In addition, it was revealed that a big toe and a little toe of elderly women showed a tendency concentrating to the central axis of feet. The foot index of elderly was smaller in width and girth. Secondly, foot size distribution table of elderly group showed wider size ranges and covered smaller sizes than the below the age of 60, meaning wide variation in foot size of elderly women. Thirdly, the multiple correlation analysis showed high correlation of foot length/girth to other measurements, suggesting these two items could be used as representative items for elderly women's shoe size specification as other age groups. Regression equations were produced using foot length/girth to estimate other measurements, suggesting such items could be estimated effectively and utilized in on/off-line shoe manufacturing shop as heel to big toe length, heel to little toe length, exterior malleouls width, instep girth, ankle girth, etc. These results imply prudent features of elderly women's foot as diversity of foot shape and wide size specification range should be applied for ergonomic shoe design for them.

Gaps between the upper edges of brassiere mold cups and the breasts are one of the most serious issues in realizing comfort wearing of commercial brassieres for small-breasted women. The surplus ease amounts causing the fit problem were measured from 3D wearing images of the small-breasted women's brassieres. The effect after the removing the surplus ease amounts from the upper edge of mold cup was approved by subjective wearing evaluation. Since the volume distribution of mold cup can also affect the wearing sensation of brassiere, the subjective wearing sensation was compared for two brassieres of different volume distributions, V_L, of which volume was concentrated at the lower cup, and V_C, which has the thickest part at the nipple. As the results, the suitable sensation for cup volume and the natural wearing silhouette could be accomplished by removing the surplus ease amounts from the upper edge of mold cup to reduce the gaps between brassieres and the breasts, which could be accomplished through an approach reducing the volume near the upper edge of mold brassiere cup and making the volume concentrated at the lower cup. These works provide a useful information on the design of the brassiere mold cups for small-breasted women. Moreover, modeling methods of 3D scan data and 3D printing technique for making more accurate mold cases used in this research can be helpful to develop and evaluate clothing products in future.

This study attempts to find out the characteristics of digital currency and currency transformation through the analytical descriptions of the literature. In the early days of the emergence of new currency, market-oriented autonomous monetary adjustment was made along with various attempts by the private sector, and then government-centered central currency management and coordination were made for the national monopoly of profits and power. Digital currency can be seen as the emergence of a new form of money that will bring about paradigm changes. CBDC can be divided into direct and indirect types. CBDC is expected to require a strategic approach by the government or firm as it will bring about changes in the ecosystem of related industries. Libra is a stablecoin designed to minimize price fluctuations, and if it succeeds in commercializing it, it is expected to bring about revolutionary changes in the financial industry around the world.
