English absolutes and free adjuncts, despite their abridged syntactic forms, function as full subordinating adverbial clauses, with their semantic roles varied according to the interpretation of the matrix clauses. This paper investigates how to represent the syntactic structures and semantic variability of absolutes and free adjuncts in a unified way, accounting for overlapping properties among various subtypes of the constructions on the one hand, and differences on the other. In the proposed analysis, the clausal properties of absolutes and free adjuncts are captured by the subject selecting property and the clausal meaning associated with a predicative phrase, thus not calling for a null verb or complementizer. In classifying and defining diverse subtypes of the constructions via type constraints, the present work also provides an account of different uses of with involved in absolutes and free adjuncts.

In tall constructions, the outriggers are regarded as a structural part capable of effectively resisting lateral loads. This study analyses the efficacy of hybrid outrigger system in high rise RCC building for various structural parameters identified. For variations in α, which is defined as the ratio of the relative flexural stiffness of the core to the axial rigidity of the column, static and dynamic analyses of hybrid outrigger system having a virtual and a conventional outrigger at two distinct levels were conducted in the present study. An investigation on the optimal outrigger position was performed by taking the results from absolute maximum inter storey drift ratio (ISD_max), roof acceleration (acc_roof), roof displacement (disp_roof), and base bending moment under both wind and seismic loads on analytical models having 40, 60 and 80 storeys. An ideal performance index parameter was introduced and was utilized to obtain the optimal position of the hybrid outrigger system considering the combined response of ISD_max, acc_roof, disp_roof and, criteria required for the structure under wind and seismic loads. According to the behavioural study, increasing the column area and outrigger arm length will maximise the performance of the hybrid outrigger system. The analysis results are summarized in a flowchart which provides the optimal positions obtained for each dependent parameter and based on ideal performance index which can be used to make initial suggestions for installing a hybrid outrigger system.

Ordinary concrete uses aggregate sufficiently soaked with water, and is weighed, mixed with other materials and placed in accord with performances required in the construction field. Recently special concrete with high fluidity and durability is required but it is difficult to use top-quality concrete due to lack of high-quality aggregate, delayed transportation because of traffic jam, etc. In addition, sometimes the use of a remicon is inevitable just for small-sized concrete constructions or it is difficult for a remicon to reach remote construction places such as mountainous areas. To solve these problems, this study attempted to pack concrete materials. In other words, it is to instantize concrete. This study dried aggregate, a material of concrete, and compared the change of absorption phase of the aggregate in water and in paste in order to examine the effect of the dryness of aggregate on its absorption rate and, based on the absorption rate, decided water addition ratio necessary for the reduction of unit quantity caused by the use of dry aggregate in designing concrete mixture, and analyzed the properties of unhardened concrete according to water addition ratio in manufacturing concrete using aggregate in the state of absolute dryness and in the state of surface dryness.

To develope the fundamental models suitable for slope stabilization and scenic effect improvement of the roadside slopes, this study has continuously been conducted for last about 10 years through the field survey and observations on the roadside slopes of 100 plots located in the Capital region. The results obtained could be summarized as follows: 1) In general, due to unsuitable treatments and constructions to the man-made bare slope characteristics of the roadsides, the treatment aims for stabilizing and improving the scenic beauty of the slopes have not been successfully reached in the surveyed regions. 2) Particularly, because of insufficiency of the follow-up maintenance techniques to the roadside slopes treated, denudations of slope scenery established as well as the withering of the vegetation planted have been accelerated for the most part of the slopes treated. 3) 6 fundamental models for the roadside slope treatments have been developed and could be edaptable to the nation-wide purposes. The fundamental models are the model of forest scenery match plantation, roadside scenery establishment, denuded land rehabilitation, rock slope greenification, absolute stabilization, and environmental plantation belt establishment, respectively.
