This article aims to analyze some conditions for the reinforcing social security rights of atypical construction workers, and their socio-economical effects, and furthermore, to explore political measures for compliance with obligation of the four basic social insurances. Although the construction industry is one of the pivotal industry sectors, which contributes to the economic development, it is a typical industry sector, half of whose manpower is atypical and irregular. This kind of reality results especially from its own sectoral features and employment structure. We will argue that our society needs political measures for compliance with obligation of the basic social insurances for the construction workers, and it would help the reinforcing social safety net of the precarious construction workers, and furthermore enhancing competition in the construction industry. For this purpose, we will suggest concrete conditions for compliance with obligation of the basic social insurances and prove its positive socio-economic effects. In the end, we will propose some detailed measures like direct construction, introduction of the prevailing wage, etc. for this politic approach.

The purpose of this study is to test empirically the effect of Islamic business ethics and market conditions on organizational performance in state-owned construction companies in Indonesia. Data collection in this study was conducted online and the total number of data used was 81 respondents, both directors, heads of departments, and managers (general and project). This study uses a partial least squares structural equation model (PLS-SEM) with a quantitative approach that aims to test hypotheses and relationships between variables, such as Islamic business ethics, market conditions, project management, organizational culture, competitive strategy, and organizational performance. This study shows Islamic business ethics has a significant direct effect on organizational performance. Market conditions do not have a direct significant effect on organizational performance. Meanwhile, the mediating variables of project management and competitive strategy have a significant direct effect on organizational performance. Organizational culture does not have a significant influence on organizational performance. Conversely, market conditions have a significant influence through the mediating variables of project management and competitive strategy on organizational performance. Besides, this study is an attempt to determine the impact of the criteria factors affecting the measurement of the performance of construction organizations in Indonesia in terms of the external environment and organizational structure.

Since the conventional direct approaches are hard to be applied for damage diagnosis of complex large-scale structures, a two-step approach for diagnosing the joint damage of framed structures is presented in this paper by using artificial neural networks. The first step is to judge the damaged areas of a structure, which is divided into several sub-areas, using probabilistic neural networks with natural Frequencies Shift Ratio inputs. The next step is to diagnose the exact damage locations and extents by using the Radial Basis Function (RBF) neural network with the second Element End Strain Mode of the damaged sub-area input. The results of numerical simulation show that the proposed approach could diagnose the joint damage of framed structures induced by earthquake action effectively and has reliable anti-jamming abilities.

The Swedish construction sector has been criticized in media for being corrupted, unproductive and conservative. Several incidents, e.g. cartels, work on the side without paying tax and moisture problems, have had a great deal of attention. Of that reason has the government initiated a number of investigations in order to identify the major problems in the construction industry. Further, they have initiated a development of a tool aimed for (a) to identify risks, (b) to avoid poor quality costs, and (c) to direct towards increased quality and effectiveness in building and civil engineering projects, from a client perspective. The UK Constructing Excellence has often been held up as a model during the debate. However, the Swedish general culture differs from the British, as well as the Swedish system differs from the British. The purpose of this paper is to describe the program for developing the system, including the purposes with the system, identified starting points and demands and the approach/method for the development.

In the dynamic construction industry, particularly within the United States Army Corps of Engineers (USACE), ensuring worker safety in high-risk environments is a critical challenge. This study explores the integration of wearable technology in construction safety, focusing on its potential to enhance personal protective equipment (PPE). The primary goal of this study is to understand the factors influencing USACE employees' acceptance and adoption of wearable technology. Additionally, the research aims to assess the experiences of employees who have already used such technology to identify its practical benefits and levels of user satisfaction. A mixed-method approach was employed to gather qualitative insights from interviews with USACE safety experts and quantitative data from an online survey of USACE personnel. The findings indicate a general reluctance among workers to adopt wearable technology for monitoring work activities, mainly due to privacy concerns, usability issues, and perceived additional workload. However, there is interest in technologies that provide direct safety benefits, such as hazard alerts. This study illuminates the gap between the potential benefits of wearable technology and its current level of acceptance in the construction industry. It identifies the need for strategies to enhance worker acceptance and offers recommendations for future research.

The purpose of this paper is to present the details of design procedure of a nonlinear regulator by Riemannian geometric approach and to applied it to the case of a double-effect evaporator. A nonlinear geometric model is proposed on a direct sum space of a state vector and a control vector as well as in the previous parers by the authors. The geometric model is derived by replacing the orthogonal straight coordinate axes of a linear system on the direct sum space with the curvilinear coordinate axes. The integral manifold of the geometric model becomes homeomorphic to that of fictitious linear system. For the geometric model a nonlinear regulator with a performance index is designed renewedly by the procedure of optimization. The construction method of the curvilinear coordinate axes on which the nonlinear system behaves as a linear system is discussed. To apply the above regulator theory to double-effect evaporators especially to the pilot plant at the University of Alberta, a suitable nonlinear model is determined by the plant dynamics. The optimal control law is derived through the calculation of the homeomorphism. As a result it is confirmed that the regulator is effective and superior to that of the conventional control.

There are direct and indirect approaches to measure the quality of rural life with comparison of urban. One of the direct approach is to survey living satisfaction of rural residents. Survey result is also important factor for the understanding of local needs in rural development. Rural Development Adminstration(RDA) has developed a survey table with 71 survey items for measuring the satisfaction of rural residents. In rural field forum which have conducted for finding the direction of rural development, the understanding of local needs with measuring the satisfaction of rural residents is important. But developed survey table is difficult to be applied in rural field forum not only many survey items but also overlapping in survey range. The purpose of this study is to suggest a field-applicable survey table in rural field forum based on results of RDA. Survey items were selected based on the importance score of RDA survey table, and weighting values were applied to each survey items. Finally, we suggested 31 items based on results with principle component and reliability analysis.

In order to overcome the problems of current approaches to metadata interoperability based on element mapping, this research proposed Master Element Framework that is an alternative approach to metadata interoperability. It is an approach to integrate metadata elements that have the same value, instead of direct mapping between similar elements. Master Element Framework is constructed to semantically integrate metadata elements in a hierarchical order and to interconnect between heterogeneous metadata standards. This approach is expected to be an alternative approach to metadata interoperability.

In this paper , a state space model for flexible beam is presented using the assumed-modes approach. The state space equation is derived for a flexible beam in which one end is connected to a motor and is driven by a torque equation and the other end is free. Many of the transfer function proposed thus far use the torque to the flexible beam as the input and the tip deflection of the flexible beam as the output. The Technique for the analysis and synthesis of the dual-input describing function(DIDF) is introduced here and the construction of a non-linear compensator, based on this technique, is proposed. This non-linear compensator, properly connected in the direct path of a closed-loop linear or non-linear control system. The above non-linear network is used to compensate linear and non-linear systems for instability, limit cycles, low speed of response and static accuracy. The effectiveness of the proposed scheme is demonstrated through computer simulation and experimental results.

This paper aims to account for direct combination of an entity type noun with the verb HA- 'do' (ex. piano-rul ha- 'piano-ACC do') in Korean, based on Generative Lexicon Theory (Pustejovsky, 1995). The verb HA-'do' coerces some entity type nouns (e.g., pap 'boiled rice') into event type ones, by virtue of the qualia of the nouns. Typically, a telic-based type coercion supplies individual predication to the HA- construction and an agentive-based type coercion evokes a stage-level interpretation. Type coercion has certain constraints on the choice of qualia. We further point out that qualia cannot be a warehouse of pragmatic information. Qualia are composed of necessary information to explain the lattice structure of lexical meaning and co-occurrence constraints, distinct from accidental information. Finally, we seriously consider co-composition as an alternative to type coercion for the crucial operation of type shift.
