The concept of a 'place' in contemporary cities has been fundamentally challenged by the social, economical changes as well as the global digital network. The complex and multi-layered contemporary everyday life blur the boundaries of the existing architectural programs. In contemporary architecture, various proposals have attempted to overcome the physical limitations. 'Activity Diagram' is one of them. Activity diagram is a diagrammatized design process In which the given program is analyzed into individual activities, then it is re-organized and finally spatialized based on the analysis. In many projects by Manuel Gausa, Ben Van Berkel and Vicente Guallart, the activity diagram is applied in various forms and they are explained with theoretical backgrounds. Based on how the given program is re-organized into assembly of activities and how diagram is applied, five analytical elements were selected to critically analyze three chosen architects' case projects. In this study, it is found that architects attempt to construct an open networked world where diverse activities are freely interconnected in spite of some fundamental limitations of activity diagrams.

In case of domestic performance hall, it is real situation that the demand of multipurpose hall that accommodative a lecture, gathering activity, drama and concert than a professional performance hall such as opera house, is on increasing. Accordingly, since such multipurpose hall, in view of its characteristics, is emphasizing the clearness of sound, also it requiring the repletion or abundance of sound simultaneously, it could be said that the sufficient examination and plan with regard to the architectural acoustics design is indispensable. However, since most of multipurpose hall has ever been designed and constructed without any consideration on an acoustic factor, many problem points are generating. Standing on such viewpoint, this Research has measured the physical acoustic characteristics about the small-scaled multipurpose hall recently built without any acoustic consideration, and through the above, tried to grasp the acoustic defect and controversial point thereof. It is deemed that such study result could be utilized as an important material for improvement the acoustic performance of the multipurpose hall.

This study has main purpose to understand and interpret the house Nok-U-dang, an upper class built in Chosun dynasty, not by outsider researcher's view but insider dweller's view. To interpret correctly, dweller's everyday life in the space and form is examined on a microscale beyond the physical space and form of the house, main object of architectural history To understand the present form exactly, the study restore traditional life in past era, 1940s. Main method of restoration is the ethnographic interview, based on cultural anthropology. Like any other upper-class house, the house has been influenced under ruling Confucian ideology in Chosun dynasty: separation of man's and woman's quarters and hierachical arrangement by generation, and worshipping ceremony for ancestor. However, it is by practical management for agricultural production that every court and building of the Noku-Dang can be explained correctly; preparing seed for sowing, tool storing, preparing and serving meal for laborers, making manure, harvesting, threshing grain, storing grain and so on. Precedent studies interpreted the house by the Confucian principle too much and made conclusion of dignity and austerity of ritual: woman's quarter, is closed and serene space. However this study shows that the space is semi-opened and composite space by agricultural works. And the Sarangchae, master's quarter, is located properly at visual center to control every agricultural activity.

Jeong Woo-tae(?-1809) was a military official who had worked as Byeol-Gan-Yeok in the governmental construction works during the late 18th century through the early 19th century. Byel-Gan-Yeok, literally a special technician, was an official post in the governmental construction works that carries specific technical tasks from the mid 18th century. Over 30 years, Jeong Woo-tae had devoted himself in the construction of various royal tombs, city walls, and palace buildings. He showed superb and various techniques in the works of stone carving and architectural details. After finishing the construction of the tomb of King Jeong-jo's father successfully, he was appointed as a governor of a rural town. Being on duty of the governor, he used to participate in the construction works as a technician. He also made a couple of innovative devices in the field of construction, like a carrying apparatus, Byel-Nok-No. His works secured the setting up of the post of Byel-Gan-Yeok in the governmental construction system in the 19th century. But his technical achievement remained as his own private works rather than developing to the universal growth of the craftsmen's skill. This might be a limitation of the Byel-gan-Yeok's role, whose position was remained in the midway between official and craftsman.

미술작품이나 건축물에 수학 원리가 내재해 있다. 중등학교 학생들이 미술작품에서 이러한 원리를 찾는 일은 중요하다. 하지만, 미술작품이나 건축물에 내재한 수학 원리를 찾는 것 자체만의 학생 활동은 미술교육 본연의 목적을 달성하기 어렵다는 것이다. 그러므로 미술 교육의 목적을 달성하기 위해서는, 미적 체험과 작품 감상을 통하여 학생들 스스로 미술작품에서 수학 원리를 찾고, 이 원리를 응용한 새로운 작품을 구성하고, 감상하고, 표현하는 활동이 필요하다는 것이다. 이러한 관점에서, 본 논문에서는 수학 원리가 내재한 몇 몇 미술작품이나 건축물을 조사하였다. 그리고 학생 스스로 미술작품에서 수학 원리를 찾고, 이 원리를 이용하여 새로운 작품 구성 활동 능력을 기대할 수 있는 프로그램 모델을 구성하였다. 또한, 수학 원리가 내재한 Escher의 작품을 예로 들어 프로그램에서의 교사활동과 학생활동을 가상적으로 구성하였다.

When manufacturing self-healing concrete using bacteria, nutrients are added to increase the activity of the bacteria. Although many researches have focused on the effects of nutrients containing bacterial healing agent on concrete, few have studied the effects of sole nutrient on self-healing of cement composites. Bacterial nutrients, like commercial chemical admixtures, affect hydration characteristics such as flow, setting, hydration heat, mechanical strength of cement composites and also affect the self healing of cement composites by hydration of unhydrated particles. In this study, effect of the four nutrient commonly used in the existing literature on the hydration characteristics of cement composites by its addition was investigated. Flow, setting time, hydration heat, compressive strength have studied for each nutrients added by 1.5% and 3% of cement weight. Experimental results shows that urea and calcium-nitrate can be used up to 3% without significant detrimental effect on cement composites. Addition of calcium-lactate up to 1.5% show better compressive strength than control, but addition of 3% show almost non-hydration. Yeast extract shows detrimental effects on the composites regardless of the amount added.

Wetlands are generally thought to be among the most fertile and productive ecosystems of the world. They provide a variety of ecological functions to the landscape. In recent years there has been considerable research activity to generate more scientific documentation on the ecological functions of wetlands. Many pollutants released to the environment settle and accumulate in the silt and mud called sediment on the bottoms of wetlands. Contaminated sediment can cause adverse effects to aquatic organism and eventually to ecological system. Sediment toxicity test with water fleas has been done by standardized preparation method of pore and elutriate water methods described in the literature for the need to protect Woopo wetlands. The results of Daphnia magna, Ceridaphnia dubla and Simocephalus sp. toxicity test were compared and discussed in terms of the relative sensitivity and discrimination abilities with both pore and elutriate water obtained from the sediments of Woopo wetlands.
