Skin Architecture', which has been an important topic of architectural discourse in the recent past, is playing an even greater role in the design expression of architectural materials nowadays. The purpose of this study is to define the epidermal conception about material matter and to discover the various modes of visual effect in the use of architectural materials.Epidermal thought is expressed in different forms, ranging from a simple covering made up of materials of all kinds , removable or technological wrappings. Analyzing the recent experiments from the works of Bernard chumi, Herzog & de Meuron, Peter Zumthor, Gigon & Guyer , it can be argued that the skin is a good emotional approach in the design expression of architectural material matter as epidermal concept since the 1980's.

'Transparency', which has been an important topic of architectural discourse in the recent past, is playing an even greater role in architectural expression nowadays. The purpose of this study is to define the prevailing conceptions about transparency and to discover the various modes of this design effect in architectural space. By using partial or complete of transparency in a structure, designers are able to express themselves more profoundly. The perception between exterior and interior, transformation of day into night and conditions arising from spatial overlapping create an atmosphere which deepens the quickly of architectural design. Transparency can present as void what in reality is solid. Following the period of de-construction, transparency has asserts itself in late part of the century and transparency can be considered synonymous with modernistic and refers to structure that are optically luminant or pleasant in its simplicity. Along with advancement of climate control, construction and design technologies and new material with versatility should combine to even further the diversity of transparency in architectural expression.

Port in Northern Vietnam has been playing an important role in the logistics system the country. In recent years, the cargo throughput of the region, especially, containerized cargo has increased gradually. There are totally 11 container terminals in Northern Vietnam, concentrating in Haiphong city and Quang Ninh province. Despite of increasing demand, the competition among the terminals is becoming more and more critical. The paper, firstly, summarizes factors impacting the market share of the terminals before reveal the correlation between given factors and annual container throughput. Factor analysis will be then applied to evaluate the level of terminals' logistics infrastructure. For the conclusion, strategic thinking of terminals' logistics competitiveness will be contributed to related organizations.

Today multimedia technologies are playing an increasingly important role in games, movies, and live performances. In this paper, we design a flexible interactive system integrated with gesture recognition, skeleton tracking, internet communication, and content edition using multi-sensors to direct and control the performance on stage. In this system, the performer can control the elements showed on stage through corresponding gestures and body movements during the performance. The system provides an easier way for users to change the content of the performance if they intent to do.

The aim of this study is to find phenomenological characteristics in the background and contents of Kenneth Frampton's architectural theories and their contribution to architectural phenomenology. His theories reflect on the interpretations of Modern architecture synchronically and diachronically. This difference makes Frampton have more concrete direction for architectural phenomenology. Hanna Arendt, who contribute to form Frampton's architectural theory, introduced various concepts of Heidegger's phenomenology to Frampton. And criticism of image centered late capitalism also act as a background for Frampton to relate to phenomenology. Frampton emphasized the importance of 'critical regionalism' and 'tectonic' as a poetics of construction as the resistance of globalization. All of these have relations to 'place' and 'perception' that are main themes of phenomenology. Frampton explains his theory with phenomenological terms and above all things, he assimilates concerns of architectural phenomenology with critical thinking. In these aspects, his theories can be recognized as playing an important role to the development of architectural phenomenology.

Containers are commonly used as an effective and relatively inexpensive method for transporting goods. Unfortunately, there are often imbalances between the number of import and export containers, and some ports have a surplus of empty containers while others have a deficit. The Empty Container Simulation Game was developed to address these problems. The game is a computer role playing simulation that simulates the distribution of empty containers in order to solve empty container imbalances among ports. An optimal solution is obtained by the computer using linear programming (LP). Upon completion of the game, a player's game results are displayed along with the LP solution. The game interface was designed to provide easy access and operation. This game will serve to provide an easy understanding and planning for empty container management.

Sandy dust phenomena was observed from April 19 to 23, 1988 in Seoul. During this period it rained and the precipitation was collected to investigate the rain chemistry. This study was carried out to analyzed the chemical composition of precipitation by the measurements of conditivity, cations $(H^+, NH_4^+, K^+, Na^+, Ca^{2+}, MG^{2+})$, and anions $(SO_4^{2-}, NO_3^-, Cl^-, F^-, Br^-)$ which are believed to be the major ions playing an important role in the acidity of rain water. During the period of sandy dust phenomena the range of pH value and conductivity concentration of rainwater were 6.0-6.7, 172-254 $\mu \mho/cm$. The anions and cations concentrations increased and the orders of these concentrations were $SO_4^{2-} > Cl^- > NO_3^- > Na^+ > Ca^{2+} > NH_4^+ > Mg^{2+}$. THe principal chemical compounds of rainwater were estimated at $(NH_4)_2 SO_4, CaSO_4, NaCl, and MgCl_2$.

We present an early result of a research for formalization of the characteristics and effectiveness of manufacturing performance measurement systems (PMS). Recently manufacturing PMS has been a focus of broad research efforts due to its practical role playing in managers' decision making process. There have been so many suggestive researches that explain the troubles with old cost accounting-based PMS and describe the desirable properties of PMS in strategic management of manufacturing operations. The lack of empirical investigation in this area, however, has left us unsure about what are the real characteristics that distinguish one PMS from another. In this paper, we propose a conceptual framework that can be used to describe the environment, in which a specific PMS works, the characteristic and the utilization variables of a PMS. Then we report the result of a field survey, where we found three distinctive characteristics of a PMS, contents, vertical integration, and horizontal integration. Further, we discuss the relationships of the variables with the utilization of PMS, manufacturing strategy, manufacturing improvement programs, and business performance.

The development of information and technology has brought plenty of changes to the educational environment. The prevalence of smart phones is particularly playing a huge role in shaping learning methods. Smart phones provide the opportunity to scan QR codes, which can greatly ease access to information. Due to a high recognition speed, recognition rate, and restoration rate, they can be useful tools for English teachers to use in their class. In this study, we suggest using QR codes for writing and picture descriptions. Based on this study, more research should invest in Technology Embedded English teaching models to create better English classes for students.

3D MMORPG(Massive Multi-play Outline Role Playing Game) 게임은 넓은 3차원원지형을 실시간으로 표현되어야 하며, 많은 어려움이 따른다. 본 논문에서는 이러한 지형 처리를 위하여 메쉬나 버텍스, 혹은 폴리곤으로 사실적인 지형처리와 렌드링 속도 향상을 위하여 3차원 폴리곤을 동적으로 생성시키는 방법을 이용하려고 한다. 넓은 지형을 처리하기 위해서는 전체를 한번에 표현하기보다는 페이지 단위로 처리하기 위하여 격자화된 타일로 이루어진 맵으로 처리할 수 있다. Height field 처리 기법은 일정한 영역을 페이지 단위로 구분하고 처리할 수 있다. 옥트리를 이용하여 공간을 입체적인 컬링 방법으로 분할하고, 이를 세부 수준으로 나누어 처리하기 위해 CLOD(Continuous Level of Detail) 개념을 적용할 수 있다. 거리의 변화에 따라 지명을 표현하는 vertex들을 병합 또는 삭제함으로써 그 표현의 정도를 동적으로 달리 할 수 있는 CLOD를 이용하여 카메라의 위치와 방향에 따라 적절한 폴리곤을 생성해 낼 수 있다. 본 논문은 3 차원의 넓은 외부 지형을 실시간으로 처리할 경우 발생되는 그래픽 문제를 해결하기 위해 사용되는 방법 중에서 대표적인 방법을 통하여 효율적인 처리 기법을 제시하려 한다.
