The present study focuses on the effect of staggered integration factor (SIF) on Morton effect simulation results. The Morton effect is a synchronous rotordynamic instability problem caused by the temperature differential across the journal in fluid film bearings. Convection and conduction of heat in the thin film displaces the hot spot, which is the hottest circumferential position in the thin film, from -20 to 40 degrees ahead of the high spot, where the minimum film clearance is experienced. The temperature differential across the journal causes a bending moment and the corresponding thermal bow in the rotating frame acts like a distributed synchronous excitation in the fixed frame. This thermal bow may cause increased vibrations and continued growth of the synchronous orbit into a limit cycle. The SIF is developed assuming that the response of the rotor-lubricant-bearing dynamic system is much quicker than that of the bearing-journal thermal system, and it is defined as the ratio between the simulation time of the thermal system and the rotor-spinning period. The use of the SIF is unavoidable for efficient computing. The value of the SIF is chosen empirically by the software users as a value between 100 and 400. However, the effect of the SIF on Morton effect simulation results has not been investigated. This research produces simulation results with different values of SIF.

농촌 개발 전략의 일환으로 글로벌 가치사슬로의 통합이 주목받고 있지만, 특정 통합이 성공 혹은 실패하는 원인과 메커니즘에 대해서는 알려진 바가 적다. 본 연구는 딸기 수출시장에서 진주지역의 농업인들이 생산자 주도적 가치사슬 거버넌스를 구축한 메커니즘과 그와 동반된 사회환경적 변화를 탐구했다. 이를 위해 딸기 가치 사슬의 특성을 분석했으며, 지대 이론에 의거해 진주와 논산을 비교 분석했다. 5개월에 걸친 현장조사와 이해관계자 심층 인터뷰 결과, 진주에서는 수출가능한 품종과 해당 품종에 적합한 지역 기후 조건으로 인해 자연적 진입장벽을 구축함으로써 수출시장에서의 경제적 지대를 창출했음을 확인했다. 또한 생산자 조직화를 통해 독점 지대와 국가 지원에서 비롯된 추가 수익을 유지했다. 수평적으로 연결된 농민들은 무역업체에 대한 협상력을 높이고 회원 가입을 통제하여 국가 지원에 대한 접근을 관리함으로써 생산자 주도적 가치사슬 내 지위를 공고화했다.

Functional values for wastewater treatment and atmospheric regulation in coastal wetland and rice paddy ecosystems are quantified, and an illustration is given on how to integrate biophysical parameters into a valuation framework. This is one of most controversial issues in economic analysis for wetland preservation versus wetland conversion to agricultural use. This paper includes theoretical considerations for estimating functional values of environmental ecosystems, and the integration of biophysical data and replacement cost method employed. Specific physical and geographical characteristics and data on ecosystem functions and services in coastal wetlands and rice paddies are addressed for evaluating their values in economic terms. In particular this paper indicates double counting problems and overestimation in the previous studies, and demonstrates how to avoid them and to maintain the consistency of valuation process involving a least-cost method, thus enables an accurate integration of the coastal wetland ecology and wetland economics. As a result which is far away from the previous studies, the total economic present value of wastewater assimilation by coastal wetland is estimated at 7,484,640 won/ha, and the net present value of positive effect for atmospheric regulation, negative effects for air pollution and water pollution by rice paddy is estimated at -37,934 won/ha, assuming that resources are infinitely long-lived and the annual value and the rate of discount (10%) is constant every year. In conclusion, for further reliability and validity of functional values for natural resources it is very noteworthy that a general equilibrium framework that could directly incorporate the interdependence between ecosystem functions and services would be preferred to the partial equilibrium framework.

In this study, a demolition analysis code using the adaptively shifted integration (ASI)-Gauss technique, which describes structural member fracture by shifting the numerical integration point to an appropriate position and simultaneously releasing the sectional forces in the element, is developed. The code was verified and validated by comparing the predicted results with those of several experiments. A demolition planning tool utilizing the concept of a key element index, which explicitly indicates the contribution of each structural column to the vertical load capacity of the structure, is also develped. Two methods of selecting specific columns to efficiently demolish the whole structure are demonstrated: selecting the columns from the largest index value and from the smallest index value. The demolition results are confirmed numerically by conducting collapse analyses using the ASI-Gauss technique. The numerical results suggest that to achieve a successful demolition, a group of columns with the largest key element index values should be selected when explosives are ignited in a simultaneous blast, whereas those with the smallest should be selected when explosives are ignited in a sequence, with a final blast set on a column with large index value.

The purpose of this study is to examine how France became a representative country for far-right European populism, despite its tradition of tolerance. To achieve this goal, we examine, first, how the concept of tolerance developed in France after the 16th century. Through this process, we find that within the political system, the tolerance of the liberal tradition met with universalism, a republican value, and developed into an 'institutional tolerance' that allowed 'differences' from an authoritarian perspective rather than on an equal level. This 'assimilation' policy, reflecting a 'patriarchal' and 'oppressive' institutional tolerance, formed the keynote of the immigration policy of the 20th century, which continued until the 1980s, and shows that the French government did not take practical steps for the social integration of immigrant groups under the republican universal value that does not allow 'differences.' The government came up with an 'integration' immigration policy that embraces cultural 'differences' only after encountering problems with immigrant groups. However, this was not enough to calm the antipathy towards immigrants in French society and the discontent of immigrants in French society. Also, universalism, a republican value with deep roots in France, prevented the French immigration policy from escaping its assimilationist nature even in the 21st century. In the midst of this, far-right parties have gained power by promoting xenophobic sentiments centered on immigration problems. Finally, this study also looks at how far-right populism is currently changing the French political environment.

The 3D geospatial modeling of geotechnical information can aid in understanding the geotechnical characteristic values of the continuous subsurface at construction sites. In this study, a geostatistical optimization model for the three-dimensional (3D) mapping of subsurface stratification and the SPT-N value based on a trial-and-error rule was developed and applied to a dam emergency spillway site in South Korea. Geospatial database development for a geotechnical investigation, reconstitution of the target grid volume, and detection of outliers in the borehole dataset were implemented prior to the 3D modeling. For the site-specific subsurface stratification of the engineering geo-layer, we developed an integration method for the borehole and geophysical survey datasets based on the geostatistical optimization procedure of ordinary kriging and sequential Gaussian simulation (SGS) by comparing their cross-validation-based prediction residuals. We also developed an optimization technique based on SGS for estimating the 3D geometry of the SPT-N value. This method involves quantitatively testing the reliability of SGS and selecting the realizations with a high estimation accuracy. Boring tests were performed for validation, and the proposed method yielded more accurate prediction results and reproduced the spatial distribution of geotechnical information more effectively than the conventional geostatistical approach.

The purpose of this study is to contribute to escalation of a management quality of local public enterprise through integrating local public enterprise evaluation(LPEE) and Malcolm Baldrige Model(MBM). In order to achieve the purpose, I suggested that develop an integration model of LPEE and MBM criteria and use AHP(Analytic Hierarchy Process) as a technique posting weight value to criteria. Of two suggests, it is the former to date or discuss seriously. Therefore the integration model is redesigned for leadership/strategy category(leadership, strategy), management system category(customer management system, business management system, measurement/knowledge management system), and management result category(business result, customer satisfaction result, human resource management result, financial management result).

A new GPS receiver correlator for the deeply-coupled GPS/INS integration system is proposed in order to the computation time problem of the Kalman filter. The proposed correlator consists of two early, prompt and late arm pairs. One pair is for detecting data bit transition boundary and another is for the correlator value calculation between input and replica signal. By detecting the data bit transition boundary, the measurement calculation time can be made longer than data bit period. As a result of this, the computational time problem of the integrated Kalman filter can be resolved. The validity of the proposed method is given through computer simulations.
