This paper presents the architectural aspects of the phrase analyzer that attempts to recognize phrases and identify the functional roles in the sentences in formal Japanese documents. Since the object of interest is a phrase, the current system, designed in an object-oriented architecture, contains the Phrase class, and makes use of the linguistic generalization about languages with Case markers that a phrase, whether a noun phrase, a verb phrase, a postposition (or preposition) phrase or a clause phrase, can be separated into the content and the function components. Without a dictionary, and drawing on the orthographic information on the words to parse, it also contains a class that identifies the types of characters, a class representing grammar, and a class playing the role of a controller. The system has a simple and intuitive structure, externally and internally, and therefore is easy to modify and extend.

The purpose of this study is to research about the construction of Chiseong around the Heunginjimun Gate area in the 18th century. the conclusions derived from the historical evidence of the number, location, size, and form, and construction method of Chiseong was as follows. First, the Chiseong(Square-shaped lookout) of Hanyangdoseong was built in the 29th year of King Yeongjo(1753) and can be found in the national record. Five sites of the Chiseong are currently identified. It is assumed that the Foru was installed on top of some of the Chiseongs. Second, Chiseong was destroyed sequentially in the first half of the 20th century. Third, Chiseong is a rectangular in shape and six are constructed. Fourth, Sixth Chiseong could figure out through Hengryeopungsokdo, the drawing of Jeong Seon.

Delay is one of the most critical issues for construction projects and leads to huge losses in both developing and industrialized countries. The construction sector in Rwanda, a rapidly-developing nation, is no exception. Delays can be mitigated only once we have identify their primary causes, and these may not be the same in each region. This study aims to ascertain the main critical factors responsible for delays in building construction in Rwanda through an intensive literature review and questionnaire survey. A total of 40 delay causative factors were obtained from a literature review and were further classified into nine major categories. The questionnaire survey was distributed to about 80 respondents from clients, contractors, and consultants. From the list of 40 different factors, the top twelve most critical causes were identified as stoppage of work due to cash flow constraints, delay in approving design documents, confidentiality of physical plan, price fluctuations and delay in approving significant change, change orders, delay in performing inspections, Ineffective project planning, inadequate drawing details, unqualified labor, lack of materials on the market and dishonesty.

The Purpose of this study was to enhancing sustainable participation of community gardeners by comparing general apartment complex with public lease apartment complex by drawing indices for quantitative research. This research carried out interviews and statistical research with 319. The results revealed statistically difference between 2 types of apartment, and satisfactions and intention of continuous participation is also different from each sustainable in participating in community garden are also different from each type. Overall, however, participation of female citizens, public assistance, area of plot, and effectiveness of exchange can enhance participants' continuous participation.

The Japanese construction industry has faced on lack of quality that is one of the strong confidence fields. It is said that the main reason of this trend is in the case of construction supervisor's defects. But real problems are both the degree of drawing's completion and design activities in construction phase by architect. The purpose of this paper examines that the role of construction supervisor in Japan is changing to the management field and construction conformation, based on the analysis of the WBS based on international comparison among Korea, China, the UK, the US, and Japan.

Building Information Modeling (BIM) comes to be implemented into architectural design, construction, and maintenance in Japan in order to convert design information thoughout a construction project. However, various problems are taking place in data transaction. It is not also clear about the role and the responsibility of the architects and the enginners in charge.There is a movement to establish a BIM manager as a general coordinator concerning BIM in Singapore and other countries, though it is not yet popular in Japan. This paper deals a BIM manager as a new profession in a construction project. The function and skills necessary to a BIM manager is analyzed, and the strategy of Japanese general contractors is discussed. General contractors from Japan are operating BIM in Singapore compatible with open system of supply chain. This style is different from the one in Japan even they belong to the same company. In this paper it is analyzed based on the survey in detail.

본 논문은 디지털 컨텐츠의 지적 재산권 보호를 위해 활발히 연구가 진행되고 있는 디지털 워터마킹 기술의 응용분야로서 CAD 프로그램 상에서 도안된 건축설계도면에 워터마크를 은닉하는 기법을 제안한다. 워터마크 은닉에 필요한 컴퓨터로 설계된 건축도면 정보의 추출과 CAD데이터의 특성에 맞는 워터마크 은닉알고리즘에 대해 연구하여 워터마크를 은닉하고 추출하는 실험을 하였다. 실험결과 은닉된 워터마크는 비가시성을 만족하였으며, format 변환, cropping등에도 워터마크는 추출됨을 확인하였다.

International Competition for Parc de la Villette has evoked the old architectural question that is about the conflict between unchanging architecture and ever changing time. Tschumi and Koolhaas suggested well-known solutions for it, both of which had started from the criticism of general urban design approach that ignored changing factors in time. However, this study argues that the approaches of Tschumi and Koolhaas are even opposite to each other in spite of their common aims. Influenced by deconstructivists' theories, Tschumi tries to generate the 'text' on the surface of la Villette so that the different users of the park can read it differently. The text is built by 'superimposing' different systems such as points, lines, and surfaces. This study criticizes such formalistic approach since such 'forms' do not generate any dialogue with the real users but just stay as a backdrop for irrelevant events. Meanwhile, Koolhaas concentrates on the 'ground-ness' of la Villette. What he deals with is the real ground which embraces all the potentials on it already. His 'bands' express nothing but the metamorphosis of the ground, and the ground generates the 'differences' out of itself by repeating itself ceaselessly. This study tries to clarify all those happenings and meanings by intimate investigation of various drawing works for the la Villette project by Tschumi and Koolhaas.

This study aims to analyze architectural characteristics of railway station facilities which were built with development of railroads from Japanese Colonial Period to 1950's. To achieve this goals, 7 railway stations in Gyeongju area that are worth preserving were set up as research targets. For this study, I analyzed literature of the railway station and drawings which the KORAL Daegu Branch is keeping. Railway stations without a construction drawing investigated a direct visit. After analyzing the railway station facilities, the architectural properties such as plan, elevation and section have been identified. The results are as follows. First, Each modern railway station is usually consisted of waiting room and office, and ancillary spaces have been added. Over the years, however, the space was expanded horizontally. In that case, the structure and finish materials have been changed, like now. Second, Most of the roof shape is 'Matbae'(gable roof), especially Gyeongju station and Bulguksa Station are 'Woojingak roof. The roof structure is truss structure, especially as Pratt and Scissors type, but Gyeongju Station's structure is a reinforced concrete. Third, main doorway of waiting room is located in the center of the front gable. However, small stations like 'Ahwa' and 'Ipsil' station to ensure the passengers' waiting area are placed next to the office area.
