This paper aims to classify objects and their properties represented in Korea Building Act sentences for applying to BIM-enabled automated code compliance checking task. In order to conduct automated code compliance checking, it is necessary to develop translation process of converting the building act sentences into computer-executable forms. However, since Korea building act sentences are written in natural language, some of requirements are ambiguous to translate explicitly. In this regard, the building act sentences regarding building permit requirements are analyzed focusing on the regulation-specific objects and related properties representation from noun phrases within the scope of this paper. From 1977 building act sentences and attached reference regulations, 1200 regulation-specific objects and about 220 related properties are extracted and classified. In the application for the classification, object-property database is implemented and some of application using the database and the regulation-specific classification is suggested to support to generate rule set written in computable codes.

Current geometric modeling and analysis are commonly based on B-Rep modeling and a finite elements method respectively. Furthermore, it is difficult to represent an object whose material property is heterogeneous using the B-Rep method because the B-Rep is basically used for homogeneous models. In addition, meshes are required to analyze a property of a model when the finite elements method is applied. However, the process of generating meshes from B-Rep is cumbersome and sometimes difficult especially when the model is deformed as time goes by because the topology of deforming meshes are changed. To overcome those problems in modeling and analysis including homogeneous and heterogeneous materials, we suggest a unified modeling and analysis method based on implicit representation of the model using R-function which is suggested by Rvachev. For implicit modeling of an object a distance field is approximated and blended for a complex object. Using the implicit function mesh-free analysis is possible where meshes are not necessary. Generally mesh-free analysis requires heavy computational cost compared to a finite elements method. To improve the computing time of function evaluation, we utilize GPU programming. Finally, we give an example of a simple pipe design problem and show modeling and analysis process using our unified modeling and analysis method.

This study is to contemplate an ultimate goal and new methodology the architecture and space design community should pursue forward by analyzing concepts in Kengo Kuma's idea of "Anti-object" and examining his design methods and characteristics. To this end, I reviewed space design methods and features in his book of "Anti-Object" and his architectures built around in 2000. The result is as in the followings. (1) Contact is an essential concept of "Anti-object" to connect and integrate divided materials and consciousness with time and space. (2) Elimination is a meaningful way to reverse "cohesiveness" of agglomerated cluster which is a form of object and reconstruct it into the form of passive and acceptive "Anti-object". This idea is realized through overlap of material property and removal of massing. (3) Minimization is a concept of "Anti-object" to set the temporality free from constraints of materials. Three-dimensional transparent faces and lines or patterns of porous materials can be used to remove static and coercive volume. (4) A particle is a "reflector of its environment." It rebuilds one-way or disconnected communication between human and architecture into an interactive one. Kengo Kuma materializes this "particle" by exploring positional relation with physical paths, precise details and measurements.

The problems on application for custody in CIETAC Arbitration Rule are examined in this paper. First, The issue of jurisdiction for application for custody is arisen from the expansion of material jurisdiction of CIETAC. Until 1998, CIETAC had a jurisdiction only for the cases involving foreigners, but now, it has a jurisdiction not only for the cases involving foreigners but also for domestic cases. In the cases of arbitrating disputes involving foreigners, if the parties concerned apply for the preservation of property, CITEAC shall forward the application to and obtain a ruling from an intermediate people's court in the place where the object of the application resides, or where the property is located. But in the cases of arbitrating domestic disputes, if the parties concerned apply for the preservation of property, CITEAC shall forward the application to and obtain a ruling from an ground-level people's court in the place where the object of the application resides, or where the property is located. Therefore, "People's court" in article 23 of CIETAC Arbitration Rule includes both intermediate people's court and ground-level people's court in its meaning. Second, in the cases that the party concerned submits arbitration to CIETAC, it is not permitted for the party to ask the people's court for custody of property before submitting an arbitration. But there still can be the urgent cases that interests of the party concerned are at stake, and legitimate rights and interests of the party concerned may be damaged beyond remedy, if no application for custody of property is filed immediately. In that cases, even if the party may apply for custody of property with the people's court after submitting an arbitration, it might be too late to preserve property. Therefore, Chinese laws and rules have to be revised so that the party may ask the people's court for custody of property before submitting an arbitration. When revising laws and rules, according to the today's legislation trends, it must be considered that court and arbitration tribunal both have a right to decide the custody of property. When arbitration tribunal decides it, the procedural provisions executing it must be provided. It is also required that China permit to apply preservation of evidence as well as custody of property before submitting an arbitration. It is also strongly recommended that China permit custody of property or preservation of evidence even in the cases that an arbitration is submitted to the arbitration institute which is located in foreign country, not in China.

This study selected 6 river reach, which have various curved-channel, included in an object of study as making the Nakdong River, which is a real nature river, as a point of an object of study by using SMS RMA-2 model, a 2D numerical analysis model, and applied project flood and analyzed and examined characteristic of hydrological property and super-elevation, which includes characteristic of the velocity of a moving fluid. As a result, in a river reach, whose width is wide, angle of curved-channel has impact on the velocity of a moving fluid of inside of curved-channel and in a river reach, whose width is narrow, the radius of curvature and width of the river have impact on the velocity of a moving fluid of inside of curved-channel. Also it found out that the ratio of reduction in water-level of inside of curved-channel is more bigger than ratio of increasing in water-level of outside of curved-channel when project flood is increasing and angle of curve is increasing. Based on this, this study would be used as a expectation of danger and preliminary data in planning real river or a business, that creates an environment.

In 21st century, subordinated relationship of fashion from the body has been disappearing, and fashion is understood as variable and creative field. This research aims at analysis about the relationship between the body and fashion depending on the theories about the authority and the desire. So, this utilizes between theoretical study and empirical analysis. For concentrated study, research period limits from 2000 to the present time 2010. Contemporary body and fashion have being changed into various forms and values, become complex and de-territory. Especially, body is symbol of ambivalence eroticism that gives point to sexual property, and the object of fetishism and machine having a desire. This study's purpose draw a parallel with between the limits of contemporary body that couldn't be rid of the capital and desire, and the liberty of fashion that escape from the body's influence has being changed independent and fluid space. This research's results are as follow as; contemporary de-territory fashion is expressed as 1) symbol of the object and physical material property, 2) self-transcendental instrument fashion, 3) independent spatial molding, 4) de-centering fashion.

The main objective of this study is to propose a method to enhance building safety using the Industry Foundation Classes (IFC) schema in Building Information Modeling (BIM). To achieve this goal, a fire object relationship diagram is created by using the Model View Definition (MVD) and Property Set (Pset) methodology, as well as the Work Breakdown Structure (WBS) based object relationship analysis. The proposed method illustrates how to represent objects and tasks related to fire prevention and human safety during a building fire, including variables that are relevant to these aspects. Furthermore, the proposed method offers the advantage of considering both the IFC object hierarchy and the project work hierarchy when creating new objects, thereby expanding the attribute information for fire safety and maintenance. However, upon confirmation via an IFC viewer after development, a problem with the accuracy of mapping between attributes and objects arises due to the issue of proxy representation of related object information and newly added object information in standard IFC. Therefore, in future research, a mapping method for fire safety objects will be developed to ensure accurate representation, and the scope of utilization of the fire safety object diagram will be expanded. Furthermore, efforts will be made to enhance the accuracy of object and task representation. This research is expected to contribute significantly to the technological development of building safety and fire facility design in the future.

대한민국은 산불의 위험으로부터 취약한 환경을 가지고 있으며, 이로 인해 매년 큰 피해가 발생하고 있다. 이를 예방하기 위해 많은 인력을 활용하고 있으나 효과가 미흡한 실정이다. 만약 인공지능 기술을 통해 산불을 조기 발견해 진화된다면 재산 및 인명피해를 막을 수 있다. 본 논문에서는 산불의 피해를 최소화하기 위한 오브젝트 디텍션 모델을 제작하는 과정에서 발생하는 데이터 수집과 가공 과정을 최소화하는 목표로 한 객체 이중 탐지 방법을 연구했다. YOLOv5에서 한정된 이미지를 학습한 단일 모델을 통해 일차적으로 원본 이미지를 탐지하고, 원본 이미지에서 탐지된 객체를 Crop을 통해 잘라낸다. 이렇게 잘린 이미지를 재탐지하는 객체 이중 탐지 방법을 통해 오 탐지 객체 탐지율의 개선 가능성을 확인했다.
