  • This paper develops a new VSI $\={X}-CRL$ synthetic control chart that considers convenience of use in the field, and perception of change of process applying VSI techniques to synthetic control chart, simultaneously. We found the optimal sampling interval and various control limit factor of the suggested chart using markov chain. Comparison and analysis is carried out between synthetic VSI $\={X}-CRL$ chart and other chart in the statistical aspect; $\={X}$ control chart, VSI $\={X}$ chart, another synthetic chart. In case that the process follows normal distribution, the proposed VSI $\={X}-CRL$ synthetic control chart in detecting process mean shift showed the best performance in aspect of statistical performance, regardless of control limit L of CRL/S control chart.

  • Dynamic earth pressure is considered an important parameter in the design of embedded structures. In current engineering design simplified methods developed either for yielding or non-yielding structures are utilized to predict resultant dynamic pressure. The applicability of these equations to embedded structures have not yet been reported. In this study we perform a suite of equivalent linear time history analysis for a range of embedded structure configurations. Numerically calculated dynamic pressure is shown to depend on the flexibility ratio (F), aspect ratio (L/H) of the embedded structure, and ground motion. Increase in L/H and intensity increases the magnitude of dynamic pressure. An increase in F decreases the dynamic pressure. Overall, the trends highlight the need for development of new method that accounts for F and L/H to calculate the dynamic pressure for the performance-based design of embedded structures.

  • Tobin (1993) argues that verbs can be classified according to the process/result distinction. He further claims that the grammatical development of the lexical verbs into auxiliary/aspectual verbs is motivated by the distinction. In this paper, first, I reconsider Tobin's (1993) claim in the viewpoint of the principle of persistence (Hopper 1991) or the source determination hypothesis (Bybee, Perkins, and Pagliuca 1994), which states that the meaning of the source construction determines the path of grammaticalization. I then classified tense/aspect/ modality markers according to Tobin's (1993) process/result distinction. Finally, I argue that Tobin's (1993) process/result distinction constrains the distribution of grammaticalized verbs among tense/aspect/modality markers not only in English and but also in Korean.

  • We investigated the influence of the aspect ratio (H/R) of the oxide layer on the reactor vessel heating in three-layer configuration. Based on the analogy between heat and mass transfers, we performed mass transfer experiments to achieve high Rayleigh numbers ranging from $6.70{\times}10^{10}$ to $7.84{\times}10^{12}$. Two-dimensional (2-D) semi-circular apparatuses having the internal heat source were used whose surfaces of top, bottom and side simulate the interfaces of the oxide layer with the light metal layer, the heavy metal layer, and the reactor vessel, respectively. Multi-cell flow pattern was identified when the H/R was reduced to 0.47 or less, which promoted the downward heat transfer from the oxide layer and possibly mitigated the focusing effect at the upper metallic layer. The top boundary condition greatly affected the natural convection of the oxide layer due to the presence of secondary flows underneath the cold light metal layer.

  • The cultural art would be the most competitive commercial value in the 21st century. This research is about the stage costumes of the opera 'Ch'un Hyang Jeon'which is designed and made to fit modern times and the purpose is to set the opera 'Ch'un Hyang Jeon'as groundwork for the future opera of Korea. To extend the stage costumes of the Korea opera : First, We have to inform the world about our traditional costumes and design them to express our culture. Second, Not only the costumes but also the technical aspect such as stage music, setting, and lighting and the artistic aspect should be balanced in development. Third, We need a good training system for future designers of the stage costumes.

  • This study was initiated to inquire as to why Wal-Mart failed in the Korean market. For multi-national corporations, environmental differences such as cultural and social differences among countries require business strategies to vary country by country. In Korea, Confucian Ethics are penetrated in every aspect of people's lives. An important aspect of Confucian Ethics is the role and responsibility of women in society. Considering this, businesses need to understand Korean women's preferences as consumers and develop business strategies accordingly. This study emphasizes that IS strategy is one component of the business strategy and, as such, must be rooted in business issues. Understanding that IS strategy should fit to national contexts, this study investigates the underlying process in which IT-based strategic capability is developed according to national context to gain competitive advantages.

  • Deep X-ray lithography (DXRL), a fabrication method for the production of microstructures with a high aspect ratio, plays an important role in the subsequent electroplanting process. However, secondary radiation is generated during X-ray exposure and damages the resist adhesion to the metal layer. To solve adhesion problems, we modified the conventional DXRL process, changing the sequence of polymer adhesion in DXRL process. With optimized X-ray exposure and development conditions based on a calculated and modified X-ray power spectrum, we fabricated various polymer microstructures and achieved a maximum aspect ratio of 40.

  • Measurement is used to improve software process and to help calculating software quality. It makes software project to be control and help producing software. Measuring software scale becomes important target in software development. LOC is used to measure the size intentioned aspect and function point is used to measure the function intentioned aspect. This paper discusses measurement method using function point, which fullows proposed rule, and degree of GUI (Graphical User Interface) accesses achieved by applying this measurement to web page. Applying proposed rules to web pages (specially that use much GUI such as shopping mall or auction site), there is advantage that calculate site changes on numerical value by measuring GUI degree when do site administration or update.

  • 소프트웨어 컴포넌트란 하나 이상의 기능을 갖는 독립적인 소프트웨어이며, 조림을 통해 응용프로그램을 작성할 수 있는 부품 형태의 소프트웨어를 말한다. 이미 개발되어진 컴포넌트에 기능을 추가하거나 확장하기 위해서는 새로운 컴포넌트를 개발하여 기존의 컴포넌트와의 조립을 통하여 이를 실현하거나 이미 개발되어진 컴포넌트를 수정해야 한다. 더구나 추가하고자 하는 기능이 컴포넌트의 내부에 흩어져 있는 경우에는 컴포넌트를 수정해야하는 단점이 있다. 이에 본 논문에서는 Aspect를 이용하여 컴포넌트의 기능 추가 및 확장을 가능하게 하는 컴포넌트들 간의 조립을 위한 Component Connector를 제안한다. 컴포넌트들 간의 조림정보를 표현하는 Component Connector 모델을 제시하고 요청된 조립 서비스를 수행하는 Component Connector의 실현 클래스를 정의한다. 이것은 컴포넌트 플랫폼 독립적인 모델로 나타내어지며 적용사례를 통하여 다양한 형태로의 플랫폼 종속적인 모델로 변환 가능함을 검증하고자 한다.

  • In this study, a seismic reinforcement system was developed considering the rocking behavior of walls. The rocking behavior is to rotate left and right around the vertical axis of the wall, and the development system is a method of dissipating energy by installing a damper to a large displacement part. Developed steel rod damper was used, and steel rod diameter and length(aspect ratio) were selected as variables. As a result of the experiment, it was evaluated to have excellent seismic performance when the damper length was 260mm.
