This paper is focused on the similarity of GUI design and proposes checklists for evaluating similarity of GUI design in quantitative way and more important factors in this checklists. On the first, consideration of similarity and analysis of GUI properties are made, and from these results, the categories that affect the evaluation of similarity are extracted. The categories are consisted of 5 factors, which are concept, shape, color, relation, and multimedia. The checklists from above 5 categories are tested in 3-stage, and in this paper, 11 checklists from shape, color, and relation factor of the second stage are verified by online survey. The purpose of this survey is to find out the difference between user groups(designer, computer related, etc) and more important factors in the checklists that affect the total results of similarity. In the results of survey, the checklists have no relation with the user groups and among the checklists, external shape, composition element, and design methods have impact factors on the evaluation of similarity.

Checkpoint placement is an effective fault tolerance technique against transient faults in which the task is re-executed from the latest checkpoint when a fault is detected. In this paper, we propose a new checkpoint placement strategy separating data saving and fault detection processes that are performed together in conventional checkpoints. Several fault detection processes are performed in one checkpoint interval in order to decrease the latency between the occurrence and detection of faults. We address the placement method of fault detection processes to maximize the probability of successful execution of a task within the given deadline. We develop the Markov chain model for a real-time task having the proposed checkpoints, and derive the optimal fault detection and checkpoint interval.

With the advance in mobile communication systems, the need for distributed applications running on multiple mobile devices also grows gradually. As such applications are subject to H/W failures of the mobile device or communication disruptions, compared to the traditional applications in fixed networks, it is crucial to develop any recovery mechanism suitable for them. For this, checkpointing is widely used to restart interrupted applications. In this paper, we devise an efficient checkpointing method that adopts the software agent executed at the mobile support station. The agent, called the checkpointing agent, is aimed at supporting the concept of rollback-distance (R-distance) that bounds the maximum number of roll-backed local checkpoints. By means of the R-distance, our method can prevent undesirable domino effects and heavy checkpoint overhead, while providing high flexibility in checkpoint creation.

This paper proposes a method to generate test cases in an automatic manner, based on checklist containing test cases used for testing embedded systems. In general, the items to be tested are defined in a checklist. However, most test case generation strategies recommend to test a system with not only the defined test items but also various mutated test conditions. The proposed method parses checklist in Korean file and figures out the system inputs and outputs, and operation information. With the found information and the user defined test case generation strategy, the test cases are automatically generated. With the proposed method, the errors introduced during manual test case generation may be reduced and various test cases not defined in checklist can be generated. The proposed method is implemented and the experiment is performed with the checklist for an medical embedded system. The feasibility of the proposed method is shown through the test cases generated from the checklist. The test cases are adequate to the coverages and their statistics are correct.

Pilots have used checklist as a valuable tool to improve aviation safety and to reduce human error. A checklist however is too complex for a student pilot to use with less flight experience or time than a commercial pilot. It is agreed upon such complex checklist be a factor to threaten aviation safety for student pilots. This paper has focused on a checklist by dividing it into a couple of basic three flight procedures. Making exploratory case study of student pilots, researchers could analyze the correlation between checklist factors and those of human errors. First of all, it was necessary for student pilots to be educated professional knowledge regarding aircraft structures and engines to perform preflight inspection reducing human errors. Moreover it was recommended student pilots as well as maintenance crew confirm checklist together to enhance aviation safety.

Gang-foam is used in many construction projects because it is not only precise in terms of vertical, horizontal, and specifications, but also easy to install and dismantle. However, major accidents occur every year due to non-compliance with safety rules and work order, also manuals and checklists currently in use are insufficient. Thirty-seven surveys was conducted by analyzing major accident cases of domestic gang-form construction project and deriving 20 risk factors and 43 check points. Based on the survey, the importance and appropriateness of check points were evaluated. As a result of this study, a checklist was presented, check points were placed in the order of importance based on assembly, installation, dismantling, and lifting of the Gang-form process. The checklist was organized so that workers could comply with safety rules and work order. Through this, it is expected to prevent major accidents and contribute to efficient safety management.

매서운 칼바람이 부는 겨울은 날씨가 추워지는 만큼 건강관리에도 신경을 써야 하는 계절이다. 특히 심근경색은 더더욱 그러하다. 최근 런던열 의과대학 크리시난 바스카란교수의 연구결과에 의하면 기온 1도가 떨어지면 1개월간 심근경색이 발생할 위험이 2% 증가하는 것으로 나타났다. 본격적인 겨울에 들어서는 12월, 심근경색 전선에 이상 징후는 없는지 체크리스트를 통해 점검해보자.

무더운 여름의 열기도 처서가 지나면 더위가 한 풀 꺾여 선선한 가을을 맞이하게 되고, 백로에 접어들면 가을기운이 완연해진다. 이때가 되면 낮에는 덥고, 아침 저녁으로는 쌀쌀해져 감기에 쉽게 걸리게 된다. 특히 어린 아이일수록 면역력이 약해 성인보다 감기에 잘 걸린다. 가을의 본격적인 시작이면서 환절기인 9월, 우리 아이의 건강상태는 전반적으로 어떤지 체크리스트를 통해 진단해보고, 환절기를 건강하게 나는 방법에 대해서 알아본다.
