Tight integration of product design and process planning in the early design stage would make bigger impact as wider spectrum of design and manufacturing alternatives can be pursued and evaluated. Thus the development of systematic computer-based support for this integration is desirable. For this integration and process planning in the early design stage. the systematic method to synthesize shape of part from functional requirements is crucial. This research presents the methods of functional decomposition from overall function or product and synthesizing shape of part based on functional relations extracted from functional decomposition using planetary gear transmission system as an example.

This study analyzed the difficulty of scoring in different match situations in relation to which competitor scored first. The study analyzed the data from the 2022 Guadalajara World Taekwondo Championships. The analysis was performed for two separate weight classes: lightweight and heavyweight. Four game content variables were used: whether the athlete scored first, attack type, attack area, and game situation. Descriptive statistics, the Rasch model, and discrimination function questions were applied for data processing. SPSS and Winsteps were used for the statistical analysis, and the statistical significance level was set at 0.05. Consequently, in the lightweight class, the scoring frequency of the first scorer was high for all the game variables. In the heavyweight class, the scoring frequency for the first scorer was high for the attack type and attack area. By contrast, those who did not score first were more frequently found to be in a loss situation. By analyzing the scoring difficulties in different match situations based on whether the competitor scored first, the athletes who scored first in attack type most easily scored first. In losing situations, the athletes who scored first in attack area scored most easily, whereas those who did not score first scored most easily in body and match situations. For the heavyweight class, those who scored first in terms of attack type, counter-attack, and attack area scored the most easily while winning in body and match situations.

Function analysis and idea creation phase in Value Engineering(VE) Process is applied to manufacturing Industry for developing functions for elements of products, and in construction come to use various components like process, size of project, spaces as well as function itself due to multi-functional aspect. For this reason, VE applications to the construction industry are considered to be less frequent and efficient than to the manufacturing. To resolve this problem, a new technique of Function Integration Fast(HI FAST) and Hierarchical Value Engineering Concept Modules(HVECM) was made for practical integration and sequence of VE job Plan. Two types of function would be defined In this method, first and second function, during the job Plan process, and two function champions be selected for next creation phase process. For verification of consecutiveness of function analysis and idea creation phase for successful VE project implementation, this methodology was tested under design phase in office and IT Multi-functional building project. Make sure the successful application of this process with this method, need to develop the talent of VE experts and team members for process of function analysis and creation phase.

This study is intended to investigate if the standard of vocational rehabilitation service could be solely determined by medical standard for disability definement and to find out what alternatives are available to resolve practical problems for those who are not identified as the severely disabled by the disability definement but do experience severe handicaps at work. Through the literature review, the researcher argued that the concept of 'functional limitation' would be a criteria, and thereby applied Modified Barthel Index to measure the degree of functional limitation. In view of researching the relationship among physical impairment, functional limitation, and job status based on 381 cerebral palsied, variables such as the type of cerebral palsy and the part of paralysis, have neither direct nor indirect influence to the job status; however, the pain and the mobility have indirect effects, and the ability of self-management has direct effect on the job status. The researcher concluded that future research about disabilities needs to provide a serious thought on what it is to be defined as 'disabilities', as well as to focus on further research conceptualizing the degree of physical 'functional limitation'.

차량이 도로를 달리는데 있어서 절대적으로 꼭 필요한 타이어의 기능으로는 자동차의 하중을 지탱하고 자동차의 방향 전환 유지와, 노면 충격을 흡수 완화하며, 엔진의 구동력과 브레이킹 시 제동력을 노면에 전달하는 등의 기능이 있다. 이런 기능을 수행함에 있어 타이어의 상태는 안전과 직결된다고 볼 수 있다. 주행 중 운전자가 아무리 운전을 잘한다고 하더라도 타이어의 불량으로 인한 사고를 방지할 수는 없다. 자동차의 주행 안정성을 위한 타이어의 문제 중 타이어의 편마모는 운전자의 운전습관과 휠 얼라이먼트의 이상 등으로 타이어의 특정 부위가 마모되는 증상을 일컫는데, 현재까지 점검 방법으로는 정비사가 타이어를 눈과 손으로 점검하여 판단하고 있어서 점검하는 기준이 주관적이며, 정확하게 검증할 수 없는 것이 현실이다. 이에 본 논문에서는 현실의 애매모호한 주관적인 검증기준의 단점을 보완하고자 타이어의 실제 이미지를 디지털 영상처리 기법을 사용하여 각 타이어의 마모 정도를 체크하여 편마모를 객관적으로 점검할 수 있는 시스템을 설계하고자 한다.

프레임웍의 결함들을 효과적으로 발견하기 위해서는 테스트 실행 과정 중에서 결함들이 민감하게 감응하여 결함으로 인한 오동작의 흔적이 남겨질 수 있어야 한다 그런데 프레임웍은 개조, 합성된 확장 부위에 결합되는 후크 클래스(hook class)들의 시험에 대한 제어와 관찰이 어려운 성실을 가지고 있다. 이를 해결하기 위해 프레임웍의 정상동작 여부를 판단하는데 단서가 되는 자료(clue data)를 포착하여 외부로 드러내는 기능을 수행하는 테스트 센서타이저를 설계하였다.

현재의 스크립트 형태의 악성코드에 대한 대응 기법으로는 자바의 샌드박스(Sandbox) 모델과 흡사한 자원 제한 기법이 주로 사용된다. 하지만 이 기법의 경우 악의가 없는 스크립트 또한 제한되어 있는 자원을 사용할 수 없으며 이로 인하여 스크립트 본연의 취지인 전송된 스크립트를 통한 편의성 제공의 기능이 많은 제약을 받고 있다. 따라서 각각의 스크립트 코드의 유해 여부를 코드 수행 중에 결정하여 자원사용의 허용 여부를 결정하는 기법이 절실이 요구되며 본 논문에서는 전송되어온 코드치 위험 요소 부위를 자체 면역성을 가지도록 코드를 수정하는 기법을 제안하고자 한다.

As indicators of life quality have recently shown great improvement, alternative medicine is becoming a mainstream health care pattern, in which early stage medical examinations and treatments are usually preformed before diseases occur. In this context, the ear-acupuncture method is increasingly used these day as one of important alternative medicine treatments. In this paper, we performed an experiment of facial region color analysis with kidney ear acupuncture point irritation. For this, we collected facial image samples before and after kidney ear acupuncture point irritation under the same condition. From the samples, the change rates of K, L values of CMYK color system and Lab color system, respectively, on kidney related facial parts were extracted and analyzed to investigate kidney function improvement.

Recent studies on development of level of service (LoS) for separated sewer pipe have simply shown high-level of LoS from the perspective of users and financial/social/economical factors, which results in poor connectivity to real maintenance work. The objective of this study is to develope the evaluation indicators of level of service in the manner of function by analyzing the separated sewer pipes with FAST, function analysis systems technique, used in value engineering. The evaluation indicators suggested in this study include all the functions of separated sewer pipes and show an advantage of focused function maintenance. Moreover, developed indicators help to manage archival history and to perform asset management effectively.
