The purpose of this study is to propose an integrated curriculum for architectural studio in university to implement BIM process. There have been several BIM education methods occurred in school, but most of them are not successive courses but independent events. To integrate BIM into architectural curriculum successfully, it needs continuous and gradual approach. This study is proceeded by the research of precedent and analysis of key factors in foreign school program. Also fundamental objectives of the current domestic architectural curriculum are categorized to match the BIM process and functionality. As a result of this study, the new architectural design education process integrated with milestone of BIM tool is proposed.

This article provides an overview of the state of affairs of arbitrator disclosure obligations in Korea. It shows how Korean courts will analyze arbitrator conflicts and obligations through an evaluation of Supreme Court judgments and a case-specific analysis of the recent Oilhub case and provides a comparative perspective through a review of recent Japanese case law. Although limited to domestic arbitrations, it assesses the various grounds that courts consider when determining impermissible arbitrator conflicts based on relations with parties and when an award might be set aside as a result. With the 2016 adoption of the KCAB Code of Ethics for Arbitrators and its rigorous standards, great clarity has been brought to the landscape. The Code of Ethics marks a significant milestone in enhancing the robustness of arbitrator disclosures and guaranteeing the fairness, integrity, and transparency of Korean arbitration practice and law.

The sine sweep base excitation test campaign is a major milestone in the process of mechanical qualification of space structures. The objectives of these vibration tests are to qualify the specimen with respect to the dynamic environment induced by the launcher and to demonstrate that the spacecraft FE model is sufficiently well correlated with the test specimen. Dynamic qualification constraints lead to performing base excitation sine tests using a sine sweep over a prescribed frequency range such that at each frequency the response levels at all accelerometers, load cells and strain gages is the same as the steady state response. However, in practice steady state conditions are not always satisfied. If the sweep rate is too high the response levels will be affected by the presence of transients which in turn will have a direct effect on the estimation of modal parameters. A study funded by ESA and AIRBUS D&S was recently carried out in order to investigate the influence of sine sweep rates in actual test conditions. This paper presents the results of this study along with recommendations concerning the choice of methods.

To date, more than 150 exo-solar planets have been observed by various methods such as spectroscopic, photometric, astrometric, gravitational lensing, pulsar timing methods. However, all these are indirect methods; they do not directly image the planets. Only free-floating planets or their 'ana-log' have been directly detected so far. Thus the next milestone is the direct imaging of any kinds of planetary mass objects orbiting around normal (young) stars, which might have been associated with protoplanetary disks, the sites of planet formation. I will describe some SUBARU efforts to detect self-luminous young giant planets as companions as well as direct imaging of the protoplanetary disks of ${\~}$100 AU size. The results of near-infrared coronagraphic imaging with adaptive optics are briefly presented on AB Aur, HD 142527, T Tau, and DH Tau. Our results demonstrate the importance of high-resolution (${\~}$0.1 arcsec) direct imaging over indirect observations such as modeling based on spectral energy distributions. The SUBARU observations are a prelude to ALMA from the morphological point of view.

계획기법 이란 목적을 달성하기 위해 일련의 행동 순서를 찾는 것이다. 계획 기법을 통해 수립된 많은 행동들을 로봇 등 에이전트가 실행할 때 예기치 않은 문제들이 발생하게 된다. 이러한 문제들을 실시간으로 해결하여 에이전트가 주어진 목적을 달성할 수 있도록 하여야 한다. 그러한 문제점을 해결하는 방법에는 반응 계획기법, 재 계획기법, 그리고 지역 복구기법 등이 있다. 본 논문에서는 재 계획기법과 지역 복구기법의 장점을 가지는 이정표상태 계획기법을 간단히 제안하고 이정표 상태의 생성 방법을 연구하였다. 이정표 상태들은 수립된 계획의 모의 실행을 통하여 생성하였으며 행동 실행에 관련된 조건들의 criticality value를 이용하는 방법과 계획에 나타나는 행동들의 빈도수를 이용하는 방법을 제안 하였다.

The recently revised "Telecommunications Business Promotion and Personal Data Protection Act" is an important legal milestone in promoting the Korean telecommunications infrastructure and industry as well as protecting individuals' personal data and individuals' rights to privacy. Special characteristics of information security and privacy protection services including public goods' feature, adaptiveness, relativity, multi-dimensionality, and incompleteness, are reviewed. The responsibility of chief security/privacy officers in the IT industry, and the fairness and effectiveness of the criminal negligence in the Telecommunications Act are analyzed. An assessment of the rationale behind the act as well as a survey of related laws and cases in different countries, offers the following recommendations : i) revise the act and develop new systems for data protection, ii) grant a stay of execution or reduce the sentence given extenuating circumstances, or iii) use technical and managerial measures in data protection for exemption from criminal negligence.

A strapdown inertial navigation system fabrication utilizing dynamically tuned gyroscope was finished as a first stage development. So it's design, fabrication and tests are reported. Although this system lacks in accuracy compared with the cimballed system, factors such as low cost, small size and lightness make it useable in wide range of applications. The initial cost for investment is relatively cheap, and so it is best suitable for local development in various kind of inertial navigation system. Since all of the locally used systems are imported and even with it's close relation to the military, foreign technical transfer is practically non-existent. The independent local development of such system at a time of domestic initation in aerospace and defense industry, can be seen as a significant milestone in the advancement of the inertial navigaion system field.

This article introduces recent trends in RHC (Receding Horizon Control), also known as MPC (Model Predictive Control), that has been well recognized in industry and academy as a systematic approach for optimal design and constraint management. Constrained and robust RHCs will be briefly reviewed with milestone results. Among the diverse developments and achievements of RHCs, implementation issues will be focused on, together with the latest applications. In particular, this article introduces results on how to solve a finite horizon open-loop optimal control problem in an efficient way, together with code generation for real-time execution and easy implementation. Instead of traditional applications such as refineries and petrochemical plants, this article highlights some selected emerging applications, such as energy management systems and mechatronics, that have resulted from state-of-the-art high performance computing power and advanced numerical schemes.

A program for initial blank design in sheet forming which contains the capabilities of forward loading simulation by the finite element method and backward tracking simulation has been developed and proved the effectiveness by applying to a square cup stamping process. In the blank design of square cup stamping the backward tracing program can produce an optimum blank configuration which forms a sound net-shape cup produce without machining after forming. Another general application appears in the blank design of a cup stamping with protruding flanges one of typical automobile components. The blank configurations derived by backward tracing simulation have been confirmed by a series of loading simulations. The approach for decision of an initial blank configuration presented in this study will be a milestone in fields of sheet forming process design.

This paper revisited the key advances on System Dynamics modeling about traditional macro-economic models and economic growth structures, and then tries to elaborate a new model based on the endogenous growth theory that incorporates new growth factors, relevant to knowledge/technology as well as the Environment, into traditional growth models. Accordingly, the new model augments the acceleration and multiplier loops and the balancing ones representing market clearing mechanism with a simple numerical example. The authors thus provides macroeconomic System Dynamics analysts with a milestone to model macro-economic structures reflecting on traditional and cutting-edge theories on sustainable economic growth and general equilibrium modeling.
