The COVID-19 pandemic has led to the normalization of mask-wearing worldwide, and young children are particularly vulnerable to respiratory diseases. Children's masks come in various sizes and shapes, causing confusion among consumers who struggle to find products that can accommodate their child's unique physical conditions. This research aims to analyze the shape and dimensions of health masks designed for young children. A total of 67 mask varieties were collected, and 58 were subjected to analysis. The masks were found to have two primary shapes: foldable and beak-like, with sizes categorized as small and extra-small. The majority of masks were manufactured in Korea, and the size labeling systems varied among manufacturers. The mask materials were non-woven fabric or polypropylene, and there was diversity in terms of the adjustable earbands and the use of additional accessories. The dimensions of the masks varied depending on their shape, with significant differences in the weight and the length of the wire holes. Subsequent research should focus on conducting wearability evaluations to verify the dimensional suitability of commercially available children's health masks based on shape and size. Additionally, this study aims to provide foundational data that can assist in the development of children's masks with size ranges that differentiate them from adult masks and cater to specific age groups.

This paper describer a design expert system which determines the design values of shadow mask using Case-Based Reasoning. In Case-Based Reasoning, it is important to both retrieve similar cases and adapt the cases to meet the design specifications exactly. Especially, the difficulty in automating the adaptation process will prevent the designers from using the design expert systems efficiently and easily. This paper explains knowledge-based design support systems for shadow mask through neural network-based case adaptation. Specifically, we developed 1) representing design knowledge and 2) adaptive case-based reasoning method using RBFN (Radial Basis Function Network).

This study is intended to present the direction of art mask design development and help people's life care by producing an art mask with the motif of the characteristic of abjection concept. It went through the definition and characteristics of abject and abjection focusing on previous research, professional books and art works. The characteristics of abjection based on theoretical research are to express death with dead bodies and skulls, including the dismantling of ideal beauty standards, the expression of fragmented bodies, and the expression of sick and alienated bodies. This researcher produced 6 research works by combining the fascinating abjection, induced by ugly and disgusting abject, to design factors. These works fragmented each part of the facial form by the cutting and dismantling, and made viewers feel the abjection by giving a grotesque deformation. The results obtained through the research works are as follows. First, It was found that the abjection characteristics-applied works was helpful in the treatment of the mental wound of modern people. Second, the production of works based on the abjection characteristics paved the way to expand the scope of art mask design concepts and establish the new design ideas. Third, the application of the motif using the abjection characteristics to the art mask design showed that the use of various objects could express creative designs and secure diversity in using materials. In the future, this researcher hopes that such research will be used as the basic data of the follow-up study on art mask design, and it will help develop art mask designs.

Among many artifacts donated by Yoo Chang-jong, we duplicated and performed conservation treatment for a colored brick(J3432), a roof tile with monster-mask design(J1886) and a mould for roof tiles with monster-mask design(J1882). We focused on the restoration of the paint layer for the colored brick. As for the roof tile with monster-mask design, we cleared the existing poorly repaired part and then performed a complete conservation treatment. We would like to present the process to duplicate a roof tile with monster-mask design using a real mould, for the special exhibition entitled "Donated Tiles of Yoo Chang-jong".

The purpose of this study was to develop fashion designs using masks on the basis of plasticity of masks. This study was conducted both theoretically and empirically. In a theoretical study, mask-related research and fashion-related literature were examined. In an empirical study, masks used in collections since the 1990's were analyzed through fashion magazines and fashion web sites. Based on such theoretical researches, masks used in modern fashion collections were divided into accessories and clothing to analyze and three fashion designs were developed on the basis of results described above. This study intended to express a romantic look with primitive mood that added formative elements of a mask to the design concept of "Romantic-Primitive". First, forms of masks were simplified and deconstructed and then some methods such as textile printing, leather handicraft, or applique were expressed.

In this paper, we present an entry-level COVID-19 stand-alone digitial signage player (CoSiP) which performs not only conventional digital signage functionalities but also fever detection, face mask wearing detection, and KI-pass QR code checking. The overall design of CoSiP is proposed, and implementation of a temperature checking algorithm using a low cost thermal sensor is elaborately presented. Through experiments over datasets and against a developed CoSiP device, it is shown that the fever detection, face mask wearing detection, KI-pass QR code checking as well as signage functionalities of the proposed CoSiP work properly and reliably.

Background: Respiratory masks can provide healthcare workers with protection from biological hazards when they have good performance. There is a direct relationship between the visual specifications of a mask and its efficacy; thus, the aim of this study was to develop tools for qualitative assessment of the performance of masks used by healthcare workers. Methods: A mixed-methods design was used to develop a qualitative assessment tool for medical face masks (MFM) and particle filtering half masks (PFHM). The development of domains and items was undertaken using observation and interviews, the opinions of an expert panel, and a review of texts and international standards. The second phase evaluated the psychometric properties of tools. Finally, the validated Mask Qualitative Assessment Tools (MQAT) were used to assess six samples from 10 brands of the two types of masks. Results: MQAT-MFM and MQAT-PHFM shared 42 items across seven domains: "cleanliness," "design," "marking, labeling and packaging," "mask layers," "mask strap," "materials and construction," and "nose clip." MQAT-MFM included one additional item. MQAT-PHFM included another nine items associated with an eighth "Practical Performance" domain, and the valve version had another additional "Exhalation Valve" domain and six items. The evaluation indicated 80% compliance for MFM and 71% compliance for PFHM. "Marking, labeling and packaging" and "Layers" were associated with the least compliance in both types of masks and should be checked carefully for defining mask quality. Conclusion: MQAT can be used for immediate screening and initial assessment of MFM and PHFM through appearance, simple tools, and visual inspection.

Finite element analysis is performed for transient thermal deformation of a shadow mask inside the Braun tube and the landing shift or mislanding of the electronic beam is calclated. The shadow mask has numerous slits through which the electronic beams are guided to land on the designed phosphor. Its thermal deformations therefore cause the mislanding of the electronic beam and result in decolorization of a screen. For realistic finite element analysis, firstly the effective thermal conductivity and the effective elastric modulus are calculated, and the shadow mask is modeled as shell without slits. Next the nonlinear finite element formulation is developed for transient heat transfer on the shadow mask, wherein thermal radiation is a major heat transfer mechanism. Analysis of the resulting thermoelastic deformations is followed, from which the mislanding of the electronic beam is obtained. The present finite element scheme may be efficiently used for thermal deformation design of a shadow mask.

This study suggests a direction for stage-costume design by making stage costumes based on amusement, eclecticism, and the masquerade, which are the criteria for approaching stage costume designs according to characteristics of the mask theatre presented by P. G. Bogatyryov. The conclusions of this study are as follows. First, criteria to approach stage costume design for mask theatre can be classified into amusement, eclecticism, and masquerade according to the characteristics of the mask theatre presented by P. G. Bogatyryov. Second, the stage costume of a mongrel dog showed amusement through the expression of the image of therianthropy through the combination of a fur-lined vest and wristlet, Korean traditional trousers with the paw-prints of a dog. Third, eclecticism contains diverse characteristics and escapes from being singularly defined due to the fusion of severally different heterogeneous objects. The stage costume differently used a method of wearing clothing in a different period, of choosing clothing materials, and of expressing color in every character to indicate ambiguity to which the drama points through the integration of various expression elements. Fourth, the masquerade present characters (Taembang, Daejang, and Changseok)who simultaneously play the role of fairies after having changed into a white mask and having worn Korean a traditional overcoat (Durumagi) on the original clothes; the, result is the change of the theatrical structure into another time and space inside the theatrical scene of imagination through a concealment of the original clothing.
