Hand rehabilitation training tools are used in hospitals and at home for patients and users who require recovery of disabled hands and improvement in overall hand function. However, existing training tools are not organized into a progressive system, and they lead to repeatability operations over a period of time. As a result, patients feel free and cannot be motivated by rehabilitation, and continuous rehabilitation training is difficult. Based on this argument, the study combines one of the elements of the game called the "Cat's cradle" to enable the user to feel achievement through play and to achieve natural rehabilitation through unconsciousness. After examining the characteristics of the tool, the user's environment, the relevance of the Cat's cradle game to the training tool and to the patient's continued rehabilitation was established. And design elements were derived through professional interviews. Later, design guidelines and prototypes have been created to complement the problems associated with guidelines and prototypes by conducting usability testing and design element assessment.

This paper presents the motivation, design, and a preliminary evaluation of a virtual world builder, CLOVES. CLOVES is designed to support rapid construction of data-rich virtual environments and instruments for young children's science inquiry teaming. It provides a three-tiered programming Interface: a visual design environment, scripting layer, and low-level application programming interface targeting for multiple levels of programming expertise. It is also intended to be a collaborative medium among interdisciplinary domain experts such as educators, 3D modelers and software developers. A preliminary case study was conducted to evaluate the capabilities and effectiveness of CLOVES. The results showed that designers actively participated in decision making at every stage of the design process and shared knowledge among one another.

Many companies in Korea have been suffered from grasping the very essence in designing products what the consumer want to use since rapid development and popularization of westem style have been underwent in all fields during last three decades. The paper introduces the integrate approach, Dogu environment, to find the design solution for this problem. Dogu environment can be envisaged a extension of product environment, which adopts the Gibsonian concepts to include all spaces to achieve the ends in human behavior in addition to the material with diverse concrete shapes and colors. Logic and structure of the approach will be discussed based on design methodology and other related fields, history, social psychology and human behavior science. The application of the integrate approach to adaptive design for the storage and preservation of food has been evaluated and the future system has been deduced using the integrate approach, so called Dogu environment.

This is a methodological study that verifies the validity and reliability by translating and modifying the Korean version of Behavior Health Care Competency (BHCC) tool. This study verified the content validity, construct validity, and reliability of 230 nurses working in general hospitals. The BHCC tool was analyzed using a total of 4 factors and 16 items. The tool had a high level of reliability and validity. The BHCC is a measurement tool considering the mental health care of non-psychiatric nurses, and it has meaning in that it establishes basic material so non-psychiatric nurses can manage the patient's physical and potential psychiatric problems effectively.

Geovisual analytics is the new research area that looks fur the way to enable a truly synergetic work of human and visualization tool in analyzing spatio-temporal data. The research challenge for geovisual analytics is developing new geovisualization tools and enhancing human capabilities to analyse, envision, and reason a lot of spatio-temporal changes. With this research area, geovisual analytics is expected to be a new methodology for developing spatial decision support tools. This research is to integrate T scatter plot with computational method to classify the several patterns of the regional fright generation in Korea. The result of this work shows the capabilities provided by geovisual analytics to support spatial decision making.

Video protocol analysis is a popular and effective technique in many research disciplines including industrial design and HCI for understanding the interactions between people, and between people and machines. Analysing and transcribing video recordings is, however, notoriously time consuming, and a variety of single-user computer based tools have been developed to ease the task. This paper examines collaborative video analysis. The motivation for groupware tools for video analysis is described, and the desirable features of such tools are identified. The following section reviews related work on video analysis and on single-user video analysis tools. The review is used to derive a set of design goals for collaborative video analysis tools. We then detail prototype's user interface, its collaborative facilities, and its implementation. The preliminary evaluation is described prior the conclusions which identify directions for further work.

드론과 관련된 기술의 발전으로 인하여, 다양한 민간 및 공공 산업에서 활용되는 실정이며, 이에 따라 드론 시장 역시 확대되면서 일반인들도 드론을 접하거나 활용하는 기회가 많아지고 있다. 특히, 일반인들이 접근하기 용이하고 사용하기 쉬운 WiFi 기반의 상용 드론이 생산되면서 수요 역시 증가하는 추세이다. 이와 같이, 드론이 많이 발전하는 긍정적인 측면과는 반대로, 드론에서 발생하는 다양한 취약점으로 인하여 보안 위협이 발생한다. 최근에는 WiFi 기반의 드론들을 대상으로 공개된 도구를 사용하여 DHCP 고갈 공격의 취약점을 분석하는 연구가 진행되었으며, 공격 결과로 실제 드론이 DHCP 고갈 공격으로 인하여 IP 주소를 할당받지 못하는 보안위협이 도출되었다. 하지만, 이 연구는 대표적인 DHCP 공격 도구인 DHCPig와 Yersinia를 활용하였으며, 이 도구들은 무선이 아닌 유선 네트워크를 기반으로 제작되었기 때문에, 드론 환경에 그대로 적용하기에는 한계점이 존재하며, 실제로 발생 가능한 취약점을 검증하지 못하는 한계점도 존재한다. 따라서 본 논문에서는 WiFi 기반 상용 드론을 대상으로 DHCP 고갈 공격의 취약점을 분석하기 위하여, 공개된 도구들의 문제점을 분석하고 개선함으로써, 드론 환경에서의 DHCP 고갈 공격의 가능성을 검증한다. 본 연구 결과는 DHCP를 제공하는 드론 환경의 안전성을 향상하기 위한 지표로 활용될 것으로 사료된다.

This study was designed to verify reliability and feasibility by analyzing elderly drivers' ability test tools for older drivers aged 65 or older, which were improved in 2018 and are currently being conducted by the Korea Highway Traffic Authority. Only those aged 65 or older who voluntarily applied to the elderly driving ability evaluation system implemented by the Seoul branch of the Korea Highway Traffic Authority. The research was conducted for about 50 days until Aug. 31, 2018, starting with the registration and inspection of the first study subjects. The analysis performed a correlation analysis with existing tools and cognitive testing tools (MMSE_K) to determine their feasibility and reliability as an improved tool in 2018. As a result, the first, the speed distance, time-space memory, and dispersionism of each sub-component of the old version showed statistically significant static correlation with the sub-factor of the current version. Persistence, on the other hand, was not statistically significant to the current version. The limitations of this study were as follows. Most of the people in the study were highly educated and residents in the metropolitan area. Therefore, it is likely that the results of MSE_K, which checks cognitive and judgment skills, have been upgraded. Also, cognitive tools that are measured by computers are likely to have real measurement errors for generations who are not familiar with computers. Therefore, it is expected that improvement and development of tools for improving the limit points at the site and assessing actual operation capability will be required.

The purpose of this study was to develop and validate an instrument for analysing secondary school science laboratory classroom. Three classroom of novice teachers were observed and administered Dana's (2001) situated laboratory activity instrument. Dana's situated laboratory activity instrument consists of eight categories. Each category includes four levels. Three doctoral students and two science education specialists participated in modification of the through 15 science education graduate students. To achieve reliability, the researcher and two raters observed and analyzed three videotaped classrooms through discussion. The finalized instrument was employed in four novice teacher' classes and result indicated the instrument to be useful in identifying the inquiry level of a secondary laboratory classroom. The inquiry level of four novice teachers was confirmation or observation.
