This research focuses on the condition that people use small packaged products to do self-control easily, only to fail self-control. Taking in small packaged products by ones is definitely so successive eating situation that calories are accumulated. Although people should add up all the cases, they perceive the cases independently. This is called isolation effect. On this basis, we tried to prove isolation effect through small packaged products. In Study 1, it is assumed that isolation effect has influence on self-control intention when tempting products came into small package formats. Yet, when tempting products came in large package formats, isolation effect does not affect self-control intention. Study 1 shows us self-control intention decrease in small packaged products than in large packaged products. Also, we found out isolation effects mediated this result. Further to the result above, we tried to examine the interaction between isolation effect and regulatory focus has effect on self-control intention. The study designed 2(isolation effect: unrestrained isolation effect/restrained isolation effect) x 2(regulatory focus: promotion focus/prevention focus) and measured self-control intention of each group in study 2. Finally these hypothesis was verified by the study. What we found through the study was the interaction between isolation effect and regulatory focus has effect on self-control intention in eating small packaged formats. Moreover, Our findings extend package size research by examining isolation effect. Also, it is important to know that situation regulatory focus decrease this bias. 본 연구는 다이어트와 같은 장기적인 목표를 추구하는 과정에서 이용하는 작은 패키지 사이즈로 인해 오히려 자기 통제에 실패하는 상황에 주목하였다. 본 연구는 앞서 섭취한 사건이 전체적인 칼로리에 영향을 주는 것을 지각하지 못하고, 바로 눈앞에 존재하는 작은 패키지 사이즈의 작은 손실만을 고려하게 되는 분리 효과(isolation effect)가 발생할 것이라 보았다. 연구 1에서는 패키지 사이즈에 따라 분리 효과의 여부가 달라지며, 이에 따라 소비자의 자기통제 의도가 달라질 것이라 가정하였다. 패키지 사이즈(큰 패키지 사이즈/작은 패키지 사이즈)를 처치하고, 각 처치 이후 자기통제 의도와 분리 효과를 확인하였다. 그 결과, 제품이 큰 패키지로 제공된 조건에 비하여 작은 패키지로 제공된 조건에서 자기통제 의도가 더 낮게 나타났다. 또한, 큰 패키지 사이즈 제품 조건보다 작은 패키지 사이즈 제품 조건에서 자기 통제의도가 낮아지는 결과를 분리 효과가 매개하는 것을 확인하였다. 이러한 결과를 바탕으로 연구 2에서는 분리 효과의 처치 여부와 사건을 바라보는 방식이 달라지는 조절초점이 자기통제 의도에 미치는 효과를 검증하였다. 실험은 2(분리 효과: 분리 효과 비억제/억제) x 2(조절초점: 향상초점/예방초점)로 설계되었으며 연구 1과 마찬가지로 자기통제 의도를 측정하였다. 연구 결과에 따르면 분리 효과가 억제되지 못했을 경우, 향상 초점이 점화되었을 때 자기 통제 의도가 증가하지만 분리 효과가 억제되었을 경우에는 예방 초점이 점화되었을 때 자기통제 의도가 증가하는 것을 알 수 있었다. 이를 통해 작은 패키지 사이즈 제품을 섭취하는 과정에서 분리 효과의 억제 여부와 조절초점에 따라 자기통제 의도에 다른 영향을 미칠 수 있음을 검증하였다. 이에 따라 본 연구는 패키지 사이즈 연구에서 심리적인 기제인 분리 효과와 관련하여 확장된 연구를 하였다는 점과 이러한 편향이 덜 나타나는 조건을 조절초점을 통해 찾았다는 점에서 의의가 있다.

Shaking Table Study of the Three-Dimensional Isolation of a Cylindrical Reticulated Shell

Gui-bo Nie,Chenxiao Zhang,Zhi-yong Wang,Yu-jie Shi 한국강구조학회 2022 International Journal of Steel Structures Vol.22 No.2

A set of shaking table tests were conducted to investigate the dynamic response characteristics of a single-layer cylindrical reticulated shell (SLCRS) with three-dimensional column-top seismic isolation. The infl uence of infi lled wall on the seismic and isolation performance of the structure was investigated. The dynamic response characteristics of structures with and without seismic isolation were compared to investigate the eff ects of seismic isolation. The dynamic responses of lower-frame models with and without an infi lled wall were also compared to investigate the eff ects of the infi lled wall on the seismic isolation. Results show that the three-dimensional column-top seismic isolation improved the seismic safety of infi lled wall. At the same time, the three-dimensional column-top isolation bearing can signifi cantly reduce the acceleration and stress of the structure. The excellent isolation performance of the three-dimensional isolation bearing promises outstanding application prospects for this isolation bearing in highly seismic areas. In addition, under a small earthquake, the acceleration of the second fl oor with the isolation bearing was unfavorably magnifi ed. Therefore, the seismic performance of the acceleration-sensitive nonstructural components should be improved when the three-dimensional column-top seismic isolation is applied in the areas of low seismicity. The test data and conclusions obtained in the present study can provide theoretical and technical support for the actual engineering application of such three-dimensional seismic isolation bearings.

Site-response effects on RC buildings isolated by triple concave friction pendulum bearings

Sevket Ates,Muhammet Yurdakul 사단법인 한국계산역학회 2011 Computers and Concrete, An International Journal Vol.8 No.6

The main object of this study is to evaluate the seismic response effects on a reinforced concrete building isolated by triple concave friction pendulum (TCFP) bearings. The site-response effects arise from the difference in the local soil conditions at the support points of the buildings. The local soil conditions are, therefore, considered as soft, medium and firm; separately. The results on the responses of the isolated building are compared with those of the non-isolated. The building model used in the time history analysis, which is a two-dimensional and eight-storey reinforced concrete building with and without the seismic isolation bearings and/or the local soil conditions, is composed of two-dimensional moment resisting frames for superstructure and of plane elements featuring plane-stress for substructure. The TCFP bearings for isolating the building are modelled as of a series arrangement of the three single concave friction pendulum (SCFP) bearings. In order to investigate the efficiency of both the seismic isolation bearings and the site-response effects on the buildings, the time history analyses are elaborately conducted. It is noted that the site-response effects are important for the isolated building constructed on soft, medium or firm type local foundation soil. The results of the analysis demonstrate that the siteresponse has significant effects on the response values of the structure-seismic isolation-foundation soil system.

천영수(Chun Young-Soo),허무원(Hur Moo-Won) 대한건축학회 2008 대한건축학회 학술발표대회 논문집 - 계획계/구조계 Vol.28 No.1(구조계)

Seismic isolation offers an attractive approach for reducing seismic loads in the building and in its components. This paper deals with the seismic isolation effects due to variation in period ratio between superstructure and isolation layer of the building. Seismic isolation effects of the moment-resisting frames with the various period ratio were studied by nonlinear time history analysis, and the guidelines on the stiffness ratio of the superstructure and isolation layer of the building for the effective seismic isolation follow from the results of this study. It is recommended that the isolation period should be greater than 2.5 times of that of the superstructure for the effective seismic isolation.

Potentiality of Using Vertical and Three-Dimensional Isolation Systems in Nuclear Structures

Zhiguang Zhou,Jenna Wong,Stephen Mahin 한국원자력학회 2016 Nuclear Engineering and Technology Vol.48 No.5

Although the horizontal component of an earthquake response can be significantly reduced through the use of conventional seismic isolators, the vertical component of excitation is still transmitted directly into the structure. Records from instrumented structures, and some recent tests and analyses have actually seen increases in vertical responses in base isolated structures under the combined effects of horizontal and vertical ground motions. This issue becomes a great concern to facilities such as a Nuclear Power Plants (NPP), with specialized equipment and machinery that is not onlyexpensive, but critical to safe operation. As such, there is considerable interest worldwide in vertical and three-dimensional (3D) isolation systems. This paper examines several vertical and 3D isolation systems that have been proposed and their potential application to modern nuclear facilities. In particular, a series of case study analyses of a modern NPP model are performed to examine the benefits and challenges associated with 3D isolation compared with horizontal isolation. It was found that compared with the general horizontal isolators, isolators that have vertical frequencies of no more than 3 Hz can effectively reduce the vertical in-structure responses for the studied NPP model. Among the studied cases, the case that has a vertical isolation frequency of 3 Hz is the one that can keep the horizontal period of the isolators as the first period while having the most flexible vertical isolator properties. When the vertical frequency of isolators reduces to 1 Hz, the rocking effect is obvious and rocking restraining devices are necessary.

지역사회의 참여적 속성이 사회적 고립과 식품미보장 사이의 관계에 미치는 영향에 관한 다층분석

김욱진 ( Wook Jin Kim ) 한국사회보장학회 2013 사회보장연구 Vol.29 No.1

This study aims to examine the effects of participatory nature of community on food insecurity and the relationship between social isolation and food insecurity to determine the existence of contextual effect of neighborhood. Data were obtained from two sources - Wave I (2009) of the Seoul Welfare Panel Data and the 2006 Seoul Survey Final Report - which were later merged for analysis. For multi-level analysis, a Generalized Linear Mixed Model approach was used. Findings are to follow. First, the probability of experiencing food insecurity varies across communities. Second, social isolation increases the probability of experiencing food insecurity. Third, participatory nature of community makes little impact on the probability of experiencing food insecurity. Fourth, participatory nature of community weakens the positive effect of social isolation on food insecurity. However, not all types of residents` participation have equal negative moderating effects: only participatory activities related to neighborhoods self-governing (e.g., neighborhood meetings or apartment-complex meetings) have the substantial effect to decrease food insecurity rates of the socially isolated. Findings suggest that policy interventions and practice efforts to promote residents` participation in order to address food insecurity can be successful only when they target the socially isolated populations, simultaneously strengthening neighborhoods self-governing capacities. In brief, the conclusion of this study is that the neighborhood contextual effects do exist only in a considerably limited form.

Design and Analysis of Isolation Effectiveness for Three-dimensional Base-seismic Isolation of Nuclear Island Building

Xiuyun Zhu,Gao Lin,Rong Pan,Jianbo Li 한국원자력학회 2022 Nuclear Engineering and Technology Vol.54 No.1

In order to investigate the application of 3D base-seismic isolation system in nuclear power plants(NPPs), comprehensive analysis of constitution and design theory for 3-dimensional combined isolationbearing (3D-CIB) was presented and derived. Four different vertical stiffness of 3D-CIB was designed toisolate the nuclear island (NI) building. This paper aimed at investigating the isolation effectiveness of3D-CIB through modal analysis and dynamic time-history analysis. Numerical results in terms of dynamicresponse of 3D-CIB, relative displacement response, acceleration and floor response spectra (FRS)of the superstructure were compared to validate the reliability of 3D-CIB in mitigating seismic response. The results showed that 3D-CIB can significantly attenuate the horizontal acceleration response, and afair amount of the vertical acceleration response reduction of the upper structure was still observed. 3DCIBplays a significant role in reducing the horizontal and vertical FRS, the vertical FRS basically do notvary with the floor height. The smaller the vertical stiffness of 3D-CIB is, the better the vertical isolationeffectiveness is, whereas, it will increase the displacement and the rocking effect of superstructure. Although the advantage of 3D-CIB is that the vertical stiffness can be flexibly adjusted, it should bedesigned by properly accounting for the balance between the isolation effectiveness and displacementcontrol including rocking effect. The results of this study can provide the technical basis and guidance forthe application of 3D-CIB to engineering structure.
