  • To reduce the shock in shifting, the clutches and the brakes in automatic transmission have to be connected smoothly and disconnected rapidly. It is PCSV(Pressure Control Solenoid Valve) that paly this role of automatic transmission. In this paper, there were two steps in the analysis of the PCSV. The first step was modeling the elctromagnet by the permeance method. The second step was modeling the hydraulic circuit by the pressure differential equa- tion. In addition to this modeling, a experiment was performed and the commercial package program was used in order to justify modeling. The result of modeling coincide with the result of experiment and commercial package program. As a result, this modeling is usable in analysis of dynamic characteristics of the PCSV.

  • The paper examines the role of the informal sector on innovation activities of urban formal manufacturing enterprises in India. It provides empirical evidence on firm-level linkages between formal and informal sectors by using the World Bank Enterprise Survey, 2013-14 and the Innovation Follow-up survey, 2014. Primarily, the paper aims to examine the effect of informal sector competition on innovation in urban formal manufacturing enterprises in India. Secondly, the paper analyses the mediation effect of informal sector competition on innovations in the urban manufacturing enterprises. It determines the direct and indirect influence of business regulations and constraints on innovation outcomes through the mediation effect of informal sector competition by using the SEM "Structural Equation Modeling" guidelines. The econometric results show that informal sector competition has a negative effect on the introduction of product innovations while industry-level informal sector competition has a positive effect on product innovation through the local knowledge spillovers from the informal to the formal sector. However, the informal sector competition was found to have no significant effect on the probability of introducing process innovations. Further, the results show the inhibitive role of informal sector competition on innovation in urban formal manufacturing enterprises is more severe for firms with heavy regulatory burdens and is relatively weakened in firms with resource constraints. This suggests that the informal sector plays an important role in the NIS (National Innovation System) in India.

  • Objective: The purpose of this study was to investigate relationships among child care teachers' role conflict, organizational commitment and teacher's sensitivity. It also aimed to test the mediating effect of organizational commitment on the pathway from child care teachers' role conflict on teacher's sensitivity. Methods: A self-report survey was conducted on 301 child care teachers in Chungbuk. Descriptive, means, standard deviations, correlations using SPSS 18.0, and Structural Equation Modeling using AMOS 18.0 were all conducted in order to analyze the collected data. Results: The results indicated that child care teachers' role conflict and organizational commitment had significant direct effects on teacher's sensitivity. This study also confirmed the significant mediating role of organizational commitment on the pathway from child care teachers' role conflict to sensitivity. Conclusion/Implications: The significance of role conflict and organizational commitment suggests that the integration of individuals with less conflict and more dedication will contribute more qualitative child care services by improving sensitive interactions with young children.

  • Purpose: This study was designed to identify the structural relationships among psychosocial variables related to sick role behavioral compliance among patients undergoing hemodialysis. Methods: The subjects were 476 patients from seven major hospitals and twelve dialysis centers located in D and P cities. Data were collected using self-report questionnaires. Data analysis was done by using SPSS/WIN 18.0 and AMOS 18.0 programs for structural equation modeling, to estimate the hypothesized model. Results: This findings support that a modified path model is efficient and appropriate to explain sick role behavioral compliance among hemodialysis patients. These factors account for 80.1% of the variance of sick-role behavioral compliance among hemodialysis patients. The variables having direct effect on sick role behavioral compliance were knowledge related to hemodialysis, social support, attitude, self-efficacy and intention. Conclusion: The modified model explains the integration process of psychosocial and behavior variables for sick-role behavioral compliance among patients undergoing hemodialysis.

  • Cysteinyl leukotrienes are inflammatory mediators having important role in pathophysiological conditions such as asthma, allergic rhinitis and have been implicated in a number of inflammatory conditions including cardiovascular and gastrointestinal diseases. Most of the disease regulatory actions of the CysLTs are mediated through CysLT1 receptor. Hence in the present study, homology modeling of CysLT1 was performed because the availability of 3D structure would enhance the development of new drugs for inflammatory diseases. However the templates identified have low sequence identity which increases the complexity of modeling. Hence, homology modeling was performed using single template, multiple templates and also using threading I-TASSER server. The best model was selected based on the validation of the generated models using Ramachandran and ERRAT plot. The model developed could be useful for identifying crucial residues and docking study.

  • The production process of construction industry is different from thing of the general manufacturing, likewise various participants make temporary teamwork for success of the project through sharing of information. But the each role of participants is individually changed to step in construction process stage and moreover it has complicated, entangled interests. The Construction Management was inducted for the effective management and operation of construction project. The Key of the Construction Management success depends on the cooperative relationship relation to major participants. The domestic construction system is difficult with many trial and errors for the frequent plan change. As the building are more bigger and complicated, Building Information Modeling is demanded design and maintenance. This evaluation was done by the trust on the system as well as Construction Management. And then it applies the BIM it analyzes the example of construcrion project.

  • Recently, virtual reality technologies have been rapidly developed and realtime virtual simulation methods have been extensively employed for several application areas such as game, sports, manufacturing, military, and so on. A 3D database in realtime virtual simulation plays a key role because it makes users feel reality in virtual space. In a application view of 3D database, a systematic construction approach is required to reduce its construction time and increase its quality. However, many researches have been mostly focused on realtime graphic issues and its key technologies. In virtual simulation of transportation equipments, this paper proposes a systematic construction process of 3D database consisting of four stages as follows: 1) determine the activity space of a equipment, 2) collect data related to 3D database construction, 3) make a 3-dimensional modeling strategy, and 4) generate and evaluate a 3D model. This paper also introduces a new procedure of 3D environment modeling, which summarizes and expands our modeling experiences, to be used as a modeling guide.

  • The progressive collapse analysis of reinforced concrete (RC) moment-frame buildings under extreme loads is discussed from the perspective of modeling issues. A threat-independent approach or the alternate path method forms the basis of the simulations wherein the extreme event is modeled via column removal scenarios. Using a prototype RC frame building, issues and considerations in constitutive modeling of materials, options in modeling the structural elements and specification of gravity loads are discussed with the goal of achieving consistent models that can be used in collapse scenarios involving successive loss of load-bearing columns at the lowest level of the building. The role of the floor slabs in mobilizing catenary action and influencing the progressive collapse response is also highlighted. Finally, an energy-based approach for identifying the proximity to collapse of regular multi-story buildings is proposed.
