The purpose of this study is to survey the present women's golf windbreaker market to develop the trendy product with supplementing design and functionality by grasping the inconvenient part through the result of the questionnaire. According to the questionnaire, 38.1% said that the armhole is the most inconvenient part by tightfitting. Therefore, a mobility of wearer was enhanced by giving shirring detail to the armhole for flexibility through inserting the elastic band with a regular interval around armhole in the design1. The swing movement was allowed to be convenient by attaching knit to the side panel. And, the sleeves were designed in the detachable form so those are allowed to be produced in two kinds such as long sleeves and short sleeves. In the design2, a zipper was inserted from the neckline to the armhole so it is designed a detachable bolero. Furthermore, it was designed to be possible to wear two different way as a jumper style and a vest style. Given wearing a vest, the sleeve part was patched knit, thereby having enhanced activity. The design1 and the design2 evaluated an objective assessment and subjective assessment. Assessment group consists of 5 subject groups and 10 expert groups to evaluate external appearance and movement adaptability. In the external appearance evaluation, the design1 obtained the better evaluation than design2. In the movement adaptability evaluation, the design1 obtained the better evaluation than the design2 for all of the items except the wrist area. In the group of professionals, the design1 obtained the better evaluation than the design2 for all of the items except the bottom area.

With the recent advancement of 4th Industrial Revolution technology, transportation systems are generating large amounts of mobility data related to the individual movement trajectories of vehicles and people. There are many constraints on utilizing mobility data containing personal information. Thus, in South Korea, the processing and generation of pseudonymized information and the analysis and utilization of this information have been managed in a dual manner by applying separate agencies and technologies through the revision of the Data 3 Act and the enactment of the Data Basic Act. However, this dual approach fails to securely support the entire data lifecycle and suffers from inefficiencies in terms of processing time and cost. Therefore, to compensate for the problems of the existing Expert Data Combination System and Data Safety Zone, this study proposes an Integrated Data Safety Zone Framework that integrates and unifies the process of generating, processing, analyzing, and utilizing mobility data. The integrated process for data processing was redesigned, and common requirements and core technologies were derived. The result is an architecture for a next-generation Integrated Data Safety Zone system that can manage and utilize the entire life cycle of mobility data at one stop.

This study considers movement-based registration (MBR). In MBR, a mobile station (MS) performs location registration whenever the number of entering cells reaches the specified movement threshold M. MBR is simple and its implementation is quite straightforward. However, it may result in more registrations than other similar schemes. An improved MBR scheme called MBIR (MBR with implicit registration) was proposed to reduce registration cost of MBR and its approximated performance was analyzed. In this study, we point out some problems of the previous analysis method and propose an exact analysis method of MBIR. Using the exact analysis method, we show that the previous analysis includes considerable errors and improvement of MBIR in our study seems to be larger than in the previous study.

In this study, it could be found that the microbial movement in soil under electric field mainly occurred by electrophoresis and electroosmosis. The contribution of electrophoresis on the microbial mobility and flux was generally higher than that of electroosmosis. In the electrokinetic(EK) bioremediation of a pentadecane-contaminated soil, the microbial population increased simultaneously at anode and cathode regions of the soil specimen because both electrophoresis and electroosmosis affected on the microbial movement. After initial operation, the microbial population was high in order of anode, middle, and cathode regions due to their negatively-charged surface and oxygen generation at anode. However, the uniform contaminant removal was achieved by the microbial movement with two-directionality.

This article investigates how Baedal Minjok(BaeMin) has grown to be a dominant mobility platform operator in food delivery sector in South Korea and what roles its brand and branding have played in the process, drawing on the idea of origination. For the purpose, BaeMin is considered as a typical platformized mobility service provider and origination is framed to be an appropriate analytical lens for the business sector. For the origination conception, unlike mainstream neoclassical theory and concepts, is able to deal fairly well with the issues of imperfect competition, imperfect information, and monopolistic brand rent, which are apparent in today's platformized mobility services. Drawing evidence from textual data, empirical analysis pays particular attention to discursive and symbolic dimensions of BaeMin's socio-spatial biography. It is found that national origination underpinning ethnicity comprises an important pillar of BaeMin's brand and branding. Another form of place-based origination is also observed to matter, especially in the varied relation between the mobility service brand's owner and consumers. However, this configuration of BaeMin's brand origination has yet to be fully stabilized, as it has faced with serious challenges including brand vandalism and anti-brand movement especially since its merger to German food delivery platform giant Delivery Hero in 2020. This origination crisis moment appears to be associated with a series of contractions intrinsic to so-called 'platform capitalism'.

'Movement' is an expanded concept of 'place' where people act, interact with one another and achieve a specific purpose at every moment. Wheelchairs, as a mobility aid, have a profound impact on improving the quality of physical and psychological well-being for the mobility disadvantaged groups who have mobility difficulties. Such mobility aids were developed mainly for outdoor activities, but in recent years, mobility aids for indoor spaces, the main living environment, are also being developed. Because indoor mobility aids generally move short distances repeatedly, this study examined the characteristics of lithium-ion batteries in short-distance driving of battery-powered wheelchairs and compared them with the characteristics of lithium-ion batteries in continuous driving. The result showed that the driving time for short-distance driving was 2.8% shorter than that of continuous driving. The current supplied to the motor was 15.4% higher for short-distance driving than that of continuous driving.

Ago the passenger who using a wheelchair was denied boarding from the airline. The ACT ON THE PROHIBITION OF DISCRIMINATION AGAINST DISABLED PERSONS prohibits discriminatory treatment of persons with disabilities in transportation. But there are situations that limits the movement on persons with reduced mobility. The international community promote to protect disabled persons and persons with reduced mobility against discrimination and to provide them with assistance when travelling by air. According to news report, the governing Council of the International Civil Aviation Organization (ICAO) has established new global core principles on air transport consumer protection. The principles cover three phases of a customer's experience: before, during and after travel, and will now be considered by ICAO's 191 Member States when they develop or review their applicable national regimes. The international community are recognizing that passengers can benefit from a competitive air transport sector, which offers more choice in fare-service trade-offs and which may encourage carriers to improve their offerings, passengers, including those with disabilities, can also benefit from consumer protection regimes. In accordance with these we will also be provided to regulations that can prevent and protect the air passenger. In this paper analyze the regulations of the international air passenger rights, point out the lack of policy.

The distributions of Cd, Cu, and Zn concentration in soil treated with one (1988) or two (1988 and 1993) applications of sewage sludge at rates of 0, 25, 50, and $100Mg\;ha^{-1}$ (dry weight basis) were determined to assess the accumulation and mobility of the heavy metals. The heavy metals accumulated almost entirely in 0 to 15 cm soil depths. Small amounts of the metals moved out of the tillage zone (0-15 cm depth) into the subsoil, but even at the high rate of sewage sludge, little movement of heavy metals occurred below 100 cm depth. The water-extractable Cd, Cu, and Zn concentrations were very low regardless of the rate of sewage sludge application. Availability of metals as determined by DTPA extraction showed the percentage of DTPA-extractable/total concentration increased with sewage sludge application. In the 0-15 cm depth of sewage sludge treated soil, the percentage of DTPA-extractable/total concentration was higher than 46% for Cd, but the value was less than 27% and 17% for Cu and Zn, respectively. The Cd, Cu, and Zn added to this calcareous clay soil by sewage sludge application were not very mobile, and the amount of plant available form was very small.

The purpose of this study is to analyze the characteristics of the non-sedentary in contemporary multi-housing planning through the understanding and interpretation of the modern nomadic life. A document research method was used to analyze and classified the spatial characteristics and development of the non-sedentary dwelling spaces since 20th century. Finally, today the applicable cases of non-sedentary space are as follows; the sharing housing, the adapting housing, and temporary housing for the multi-purpose spaces, huge spaces and the industrialization housing. First of all, in order to conform the concept of nomadism, the theory and characteristics were divided into three aspects; The concept of thought of lines, events and Rhisome, and the spatial characteristics of fluidity, multiplicity and the non-hierarchy, that is mainly based on the philosophy of Gilles Deleuze. This study attempted to analyze how the concept of non-sedentary dwelling space has been developed in what form and method they have been applied and interpreted in the historical background. It attempted to resolve the concept of movement and mobility through the experiment so that they might apply to the space of contemporary city.

Rapid increase of aging population and progressed migration from rural areas to urban areas have caused deficit of bus routes in local cities. This increasing burden of operation deficit affects the movement strategy of the transportation vulnerable who are using buses. Along with dramatically increased aging in Korea, there is an urgent need to implement a new method which can guarantee mobility rights of public transportation especially for the elderly. This study focuses on the case of Demand Responsive Transit(DRT) system that has been operating in America, Europe, Japan, etc. Kimhae(Sangdong-myeon and Saengnim-myeon) is selected as a study area. This study investigated the possibility of adopting DRT system on the perspectives of the consumer and provider by the analysis of traffic condition such as the number of transportation vehicles, present bus service and regulation and conduct of questionnaire survey which includes present bus service and DRT system and so on. In conclusion, DRT system in Kimhae city will reduce transport cost, increase affordability through the betterment of service level and secure mobility rights for the transportation vulnerable.
