  • This paper presents a commonality and variability analysis method for UML CASE tool frameworks. Commonality and Variability analysis increase extension and reusability by separating common area and variable area. We suggest class category based on property and the notation to represent commonality and variability. It is also implements frameworks based on analysis method and verify method using defect removal efficiency.

  • 제품계열공학에서 feature diagram(FD)은 개발자의 직관이나 도메인 전문가의 경험에 근거하여 작성되어, feature간의 공통성 및 가변성분석 기준이 불명확하며 비정형적인 feature의 공통성 및 가변성 분석으로 인한 stakeholder의 공통된 이해가 부족한 문제점을 내포하고 있다. 따라서, 본 논문에서는 이를 해결하기 위하여 공통된 feature의 이해를 위해 feature 속성리스트에 기반한 메타 feature모델과 feature간의 의미유사성관계를 이용한 온톨로지를 적용한 공통성 및 가변성 분석모델을 제안한다.

  • To compete global marketplace, many firms are adopting product families to increase variety, satisfy customer requirements, shorten lead-times and reduce costs. The key to a successful product family is the platform from which it is derived. When designing product families, it is important to resolve the tradeoff between product commonality and distinctiveness. To measure the commonality within a product family, it is necessary to develop the commonality index. It utilizes different parameters such as the number of common components, their cost, their manufacturing processes and so on. This paper present a new product family assessment index using the benchmarking method and considering environmental performance called green product family index(GPFI). Through the comparison analysis between some previous developed commonality indices and GPFI, we verify the suitability and effectiveness. Eventually, the proposed a new green product family assessment index can be helpful to design and develop the environmentally conscious product families.

  • 고객의 요구에 대한 빠른 대응과 유연하고 효율적으로 새로운 제품을 적기에 개발하기 위해서는 제품 플랫폼에 기초한 대량 맞춤이 절실히 요구된다. 이러한 목적을 달성하기 위하여 기업들은 상대적으로 생산비용을 낮게 유지하면서 대량생산의 이점을 유지하고 동시에 고객의 요구사항을 만족시키기 위해, product family를 도입하고 가능하면 작은 변화를 통하여 제품의 다양성을 유지하고자 한다. Product family를 설계할 때 중요한 이슈는 제품의 공통성과 차별성간의 절충점을 어떻게 찾아낼 것인가인데, 이를 위하여 개발된 것이 product family내에서 평가하는 방법이다. 본 연구에서는 product family의 공통성을 평가하기 위해 개발된 대표적인 7가지의 방법을 여러가지 측면에서 비교분석한다. 이를 위하여 두 개 회사의 컴퓨터 마우스 제품군을 대상으로 공통성 평가를 위한 비교연구를 수행하였다. 추가적으로 본 연구에서는 product family를 설계하거나 재설계할 때 공통성 평가지 수의 효과적이고 효율적인 사용방안을 위한 전략도 제시하였다.

  • Objective:This study was conducted to examine the Draw-A-Person test as a non-verbal indicator of concrete and abstract thinking. Method:Thirty child-psychiatric children and 27 normal children were individually assessed with Draw-A-person Test and KEDI-WISC, and the scores were compared between similarity test and DAP. Results:The results showed significant differences between the groups. In clinical group, there were significant correlations with DAP scores and similarity test scores, especially abstract scores on DAP were highly correlated with similarity test scores. Results indicate characteristics of abstract thinking may be more discernable on the DAP than concrete thinking in clinical group.

  • While Long Term Evolution-Frequency Division Duplexing (LTE-FDD) is regarded as one of the strong candidates for "4G" wireless broadband access in FDD field, LTE-Time Division Duplexing (TDD) is emerging as one possible migration path for WiMAX-TDD in some cases as well as the migration path for Time Division-Synchronous Code Division Multiple Access (TD-SCDMA). In this paper, we analyze the feasibility of dual mode with LTE-TDD in two combinations: dual mode LTE-FDD/TDD and dual mode Worldwide Interoperability for Microwave Access (WiMAX)-TDD/LTE-TDD. Thanks to the commonality in numerology, terminology, and frame structure between LTE-FDD and LTE-TDD, dual mode LTE-FDD/TDD looks feasible in a cost-effective manner. Thanks to the commonality in scheduling algorithm, control mechanism, and supported spectrum bands, it is shown that dual mode WiMAX-TDD/LTE-TDD looks feasible as well. It should be also noted that the commonality in numerology and frame structure is critical for building a chip while the commonality in algorithms and control mechanisms is critical to make it work.

  • The purpose of this study is to analyze the influence of number of targets on common knowledge generation and brain activity during the common life science discovery task performance. In this study, 35 preliminary life science teachers participated. This study was intentionally made a block designed for EEG recording. EEGs were collected while subjects were performing common discovery tasks. The sLORETA method and the relative power spectrum analysis method were used to analyze the brain activity difference and the role of activated cortical and subcortical regions according to the degree of difficulty of common discovery task. As a result of the study, in the case of the Theta wave, the activity of the Theta wave was significantly decreased in the frontal lobe and increased in the occipital lobe when the difficult difficulty task was compared with the easy difficulty task. In the case of Alpha wave, the activity of Alpha decreased significantly in the frontal lobe when performing difficult task with difficulty. Beta wave activity decreased significantly in the frontal lobe, parietal lobe, and occipital lobe when performing difficult task. Finally, in the case of Gamma wave, activity of Gamma wave decreased in the frontal lobe and activity increased in the parietal lobe and temporal lobe when performing the difficult difficulty task compared to the task of easy difficulty. The level of difficulty of the commonality discovery task is determined by the cingulate gyrus, the cuneus, the lingual gyrus, the posterior cingulate, the precuneus, and the sub-gyral where it was shown to have an impact. Therefore, the difficulty of the commonality discovery task is the process of integrating the visual information extracted from the image and the location information, comparing the attributes of the objects, selecting the necessary information, visual work memory process of the selected information. It can be said to affect the process of perception.

  • 다국어 자동번역이란 2개국어 이상 언어들간의 번역을 말한다. 기존의 다국어 자동번역 시스템은 크게 변환기반 transfer-based 방식과 피봇방식으로 분류될 수 있는데 변환기반 다국어 자동번역 시스템에서는 각 언어의 분석과 생성 규칙이 상이하게 작성됨으로써 언어들간의 공통성이 수용되지 못하였고 그로 인해 전체 번역 메모리의 크기가 증가하는 결과를 초래하였었다. 또한 기존의 피봇방식에서는 다국어에 적용될 수 있는 언어학적 보편성 모델을 구현하는 어려움이 있었다. 이러한 기존의 다국어 자동번역 시스템의 단점들을 극복하기 위해 본 논문에서는 언어들간의 공통성을 수용하며 또한 여러 언어에서 공유될 수 있는 공통 규칙에 의한 다국어 자동번역 시스템을 제안하고자 한다. 공통 규칙의 장점은 전산학적으로는 여러 언어에서 단지 한번 load 되기 때문에 전체 번역 메모리의 크기를 줄일 수 있다는 것과 언어학적으로는 문법 정보의 작성.수정.관리의 일관성을 유지할 수 있다는 것이다.

  • This research examines the philosophy of Toegye and Spinoza in the postneo-Confucian and post-modern perspective in emphasizing the activity of Ri(理) and reason beyond the similarities of system in their thought. There is no disagreement in viewing Toegye and Spinoza as balanced opposites in their attempts to harmonize man and nature. In this discussion, I will infer the similarities of Toegye and Spinoza in terms of an 'activity-passivity' thesis.
