Subtalar joint instability (STI) is one of the causes of persistent hindfoot pain even after treatment for ankle instability. Diagnosis of STI is often neglected because it is a poorly understood concept. However, understanding of the anatomy and injury mechanism of the subtalar joint is a prerequisite of appropriate treatment. Patients with STI usually complain of several symptoms, such as recurrent sprains or a giving way sensation and rolling over. Recently, various diagnostic tools and treatment methods have been investigated. This study was undertaken with the aim of helping clinicians by providing a comprehensive understanding of STI.

앱을 통해 기부가 이루어지는 모바일 기부 플랫폼이 증가하고 있다. 모바일 기부 플랫폼은 사용자들의 지속 참여를 위해 재미나 건강과 같은 요소들을 핵심 가치로 내세우고 있다. 이는 기존의 오프라인 기부 플랫폼에서는 찾아볼 수 없었던 새로운 전략이라고 볼 수 있다. 본 연구는 첫째, 모바일 기부 플랫폼이 지속적인 기부 참여를 위해 왜 새로운 전략을 취하고 있는 것인지, 둘째, 새로운 전략이 어떻게 지속적인 기부 참여를 이끌어내고 있는지에 대해 알아보고자 하였다. 이를 위해 국내의 대표적인 모바일 기부 플랫폼인 빅워크와 트리플래닛을 대상으로 사례연구를 진행하였다. 본 연구는 지속 참여 유도 기제를 파악하기 위한 이론적 틀로써 심리적 거리감과 해석수준의 관계를 설명하는 해석수준 이론을 이용하였다. 본 연구의 결과는 모바일 플랫폼으로의 이동이라는 환경적 변화에 따라 사용자들이 기부 플랫폼에 대한 심리적 거리감이 감소하였다는 것을 보여준다. 지속적인 참여 유도를 위해서는 심리적 거리감에 따라 적절한 해석수준을 형성하게 하는 것이 중요하며, 따라서 모바일 기부 플랫폼은 낮은 해석수준의 서비스 요소들을 강조하는 것으로 나타났다. 이러한 결과는 향후 모바일 기부 활성화를 위해 활용될 수 있다.

One-way authenticated key agreement protocols, aiming at solving the problems to establish secure communications over public insecure networks, can achieve one-way authentication of communicating entities for giving a specific user strong anonymity and confidentiality of transmitted data. Public Key Infrastructure can design one-way authenticated key agreement protocols, but it will consume a large amount of computation. Because one-way authenticated key agreement protocols mainly concern on authentication and key agreement, we adopt multi-server architecture to realize these goals. About multi-server architecture, which allow the user to register at the registration center (RC) once and can access all the permitted services provided by the eligible servers. The combination of above-mentioned ideas can lead to a high-practical scheme in the universal client/server architecture. Based on these motivations, the paper firstly proposed a new one-way authenticated key agreement scheme based on multi-server architecture. Compared with the related literatures recently, our proposed scheme can not only own high efficiency and unique functionality, but is also robust to various attacks and achieves perfect forward secrecy. Finally, we give the security proof and the efficiency analysis of our proposed scheme.

In recent years, energy prices have soared, which of course have increased costs for railway operators. Simultaneously, the energy market has considerably changed that in most developed countries, it is deregulated, giving railway operators an opportunity to define new ways of using energy. Efficient operation of the railway system is considered as an essential way to energy saving while an efficient management of power level helps to lower the reference subscribed power, giving access to better energy rates. It is studied on the relation between time and force for the energy efficient driving of train in railway when the train is braking according to several slips.

This study aims to investigate the relationship between consumers’ clothing consumption values, demographic features, and clothing disposal behaviors. The data were collected from 300 women aged between 20 and 59 through the online survey with the self-administered questionnaire. A series of exploratory and confirmative factor analysis was conducted to identify the dimensions of clothing consumption values and clothing disposition behaviors. Clothing consumption values consisted of six dimensions including conditional value, individuality value, fashion value, social value, practical value, and self-expression value. Clothing disposition behaviors were discovered as four dimensions such as discarding, giving, selling, and donating. A structural equation modeling analysis was employed to examine the relationship between clothing consumption values and disposition behaviors. While individuality value, fashion value, and practical value had a significantly positive impact on donating, giving, and discarding behaviors, both practical value and self-expression value negatively influenced discarding behavior. Fashion value negatively affected giving behavior. Employing a series of MANOVA, one-way ANOVA and sheffe's multiple range test, this study found that there were significant effects of age, marital status, monthly income, and monthly clothing expenses on giving and donating behaviors. This study suggests that fashion firms should be aware of clothing disposition in terms of social and environmental concerns and understand diverse consumer disposal behaviors and utilize them as a social marketing strategy.

A mass production system was implemented to reduce a manufacturing cost in a way of copying with a strong world market competition. However customer's demands are changing so rapidly and the mass production system is no longer competitive to meet the demands. FMS(Flexible Manufacturing System) has been introduced as a replacement for the mass production system, but it still does not meet system's requirements. A new manufacturing system, called a holonic manufacturing system (HMS), is emerging. This paper is giving a first approach of a HMS for a multirobot cooperative process.

Purpose: This study was conducted to identify communication principles for nurses in cancer units according to Grice's theory. Method: This study was a secondary analysis of qualitative research using conversational analysis. Results: The principles consisted of four maxims: Quality, quantity, relevance and manner and 14 strategies. For the quality maxim, 'asking what you believe to be true' and 'saying the facts you know' strategies were identified. In the quantity maxim, the strategies were 'asking single questions', 'asking open questions' and 'asking optimistic questions'. In the relevance maxim, 'asking about the same theme' and 'giving relevant explanations' strategies were identified. In manner maxim, the strategies were 'using clear expressions in asking questions', 'asking in an orderly way', 'verifying answers', 'using clear expressions in explanations', 'explaining in an orderly way' and 'verifying understanding'. Conclusion: It is expected that these strategies will help and increase the degree of cooperation for nurses in effectively communication with cancer patients.

In ahigh power amplifier design, power combiner/divider is used to connect low power amplifiers in parallel. The raidal structure of the powe combiner/divider has not only a good characteristics of port-to-port isolation but also an advantage of giving a redundancy to the structure itself by using RF switches. The parastics of a power resistor, that would be a problem in design process, are removed by both slot lines and cavity resonators, and the comon node in the circuit is rdesigned as a planar topology, and thus a new type of 4-way radial power combiner/divider is accomplished at 1840 ~ 1870 MH PCS frequency band. The insertion loss, reflection, and isolation characteristics of 40way radial power combiner/divider which can be adaptable to PCS system in this thesis are -0.3dB, -24dB,a dn -27dB respectively.
