We present selfie stick case design, which can protect upper part of Selfie Stick. Many of current products are damaged when it is carried without cases, especially upper part of the product, because protection case is irrelevant to handle in urgent or frequent use of the product. To solve this problem, we design the case part which is attached to stick. For designing the part, we considered functionality, aesthetics, portability and profitability.

The purpose of this study was to develop a 3D mesh-type impact protection pad with excellent motion adaptability and functionality by applying 3D printing technology. The hexagonal 3D mesh, which constitutes the basic structure of the pad, comprises two types: small and large. The bridge connecting the basic units was designed as the I-type, V-type, IV-type, and VV-type. After evaluating the characteristics of the bridge, it was found that the V-type bridge had the highest flexibility and tensile elongation. The hip joint pad and knee pad were completed by combining the hexagonal 3D mesh structure with the optimal bridge design. The impact protection pad was printed using a fused deposition modeling-type 3D printer with a filament made of thermoplastic polyurethane material, and the protection pad's performance was evaluated. When an impact force of approximately 6,500N was applied to the pad, the force attenuation percentage was 78%, and when an impact force of approximately 8,000N was applied, the force attenuation percentage was 75%. Through these results, it was confirmed that the 3D-printed impact protection pad with a hexagonal 3D mesh structure connected by a V-shaped bridge developed in this study can adapt to changes in the body surface according to movement and provides excellent impact protection performance.

During the installation of crude oil or gas pipelines, which pass through onshore buried pipelines or onshore pipeline from subsea pipeline to onshore plant, countermeasures need to be implemented so as to ensure a sufficient design life by protecting the steel pipes against corrosion. This can be achieved through impressed current cathodic protection method for onshore pipelines and through galvanic sacrificial anode corrosion protection method for offshore pipelines. In particular, in the case of impressed current cathodic protection, isolation joint flanges should be used. However, this makes maintenance control difficult with its installation having a negative impact on price. Therefore, in this study, the most suitable methodology for onshore pipeline protection between galvanic sacrificial anode corrosion protection and impressed current cathodic protection method will be introduced. In oil and gas transportation facilities, the media can be carried to the end users via onshore buried and/or offshore pipeline. It is imperative for the field operators, pipeline engineers, and designers to be corrosion conscious as the pipelines would undergo material degradations due to corrosion. The mitigation can be achieved with the introduction of an impressed current cathodic protection method for onshore buried pipelines and a galvanic sacrificial anode corrosion protection method for offshore pipelines. In the case of impressed current cathodic protection, isolation joint flanges should be used to discontinuity. However, this makes maintenance control to be difficult when its installation has a negative impact on the price. In this study, the most suitable corrosion protection technique between galvanic sacrificial anode corrosion protection and impressed current cathodic protection is introduced for (economic life of) onshore buried pipeline.

The endowed privilege to an established profession acts as an important motivation related to professionalization of occupations. The established profession enjoys cognitive, legal, and economic privilege. This study analyzes the professionalization process of interior design. Specifically, the study evaluates the suitability of the body of knowledge and professional ethos(i.e., protection of citizen's health, safety, and welfare), while analyzing the professionalization of interior design in the United States. The research aims at proposing a reference point for the professionalization of Korean interior design. Utilized data include research paper, court sentencing, and reports published by related professional organizations. The study concludes that 3E's are a means of professionalization of interior design, while separating interior design from interior decorating. In addition, there is no evidence to the protection of citizen's HSW. Rather, it increases service costs and restricts the job opportunities. When the public is not persuaded, the argument related to the necessity of license for the protecting citizen's HSW can be consumed as a mere rhetoric, concealing intentions for formulating a cartel. Thus, this study proposes that the professionalization of interior design may focus on the establishment of identity and body of knowledge, which are specific to interior design.

In recent years, smart clothing had been developed in order to better detect and monitor physical movement of the patient, so that such activities such as location identification and biometric recognition could be done. However, most of the sensing devices of smart clothing were limited to smart sensing sports clothing and the designs did not consider the physical characteristics and the behavior of the wearer. Therefore, this study aimed to create an open protection system by developing a wearable sensing device for health monitoring and location information. For this purpose, this study developed eleven types of wearable sensing design that could be commercially sold and worn by people who needed their biological information to be constantly monitored. The study conducted four tests in order to develop three types of sensing devices for various sensing wears. The purpose of this study was to expand the user rang of smart sensing wears, and provide a foundation for the development of distinctive wearable sensing devices reflecting the user. Furthermore, contribute to the design for the person subject to protection.

This study identified design elements of the functions required for children's ski pants. Data for this study were collected through questionnaire surveys conducted among children's ski instructors and children's sportswear developers. Five functionalities of children's skiwear were evaluated: mobility, stability, comfort, protection, and convenience. A total of 25 functional design elements related to the patterns, design details, and physical characteristics of fabrics for ski garments, were evaluated. The results of this study are as follows. First, children's sportswear developers evaluated that the pattern elements were important. Most of the pattern design elements highly related to mobility. Children's ski instructors' appraisal was that the height of the back waist was the important feature. Second, regarding the design details, children's ski instructors evaluated the size adjustment function and ventilation system as important elements. Many design detail elements were highly related in respect of stability, comfort, protection, and convenience. Third, the physical characteristics of fabric were strongly associated with mobility, comfort, and protection. As regards the physical characteristics of fabric, children's ski instructors valued anti-fouling highly, but children's sportswear developers attached more importance to the weight of the fabric. The results of this study will be useful in designing functional ski pants for children of elementary and intermediate ski levels. Since there may be limitations related to the ski level and age of children wearing ski pants, it is suggested that follow-up studies according to various groups of the ski pant wearers should be done.
