Pohang earthquake occurred on November 15, 2017, with a magnitude of 5.4. The damage of the structure caused by the Pohang earthquake was the most significant in 4-story piloti-type buildings, where the damage patterns were different according to the location of columns and walls at the first story. One building with a staircase at a corner shows shear failure at columns, and Another building with a staircase in the middle shows no failure or shear failure at staircase walls. Therefore, two different piloti-type buildings were selected; one has a staircase at a corner and another has in the middle, and the seismic behavior of the buildings were examined by nonlinear dynamic analysis applying a ground motion measured at Pohang. Analytical model well simulated the actual behavior of the piloti-type buildings during the earthquake. Analysis results showed that walls have an insufficient shear strength wherever the location of the staircase is and columns with insufficient transverse reinforcement could be failed when the staircase is located at a corner. Conclusively, structural engineers should design columns and walls in piloti-type buildings to possess sufficient capacity according to the location of staircase.

The plate-type fuel assembly adopted in nuclear research reactor suffers from complicated effect induced by non-uniform irradiation, which might affect stress conditions, mechanical behaviors and thermal-hydraulic performance of the fuel assembly. This paper is the Part II work of a two-part study devoted to analyzing the complex unique mechanical deformation and thermal-hydraulic characteristics for the typical plate-type fuel assembly under irradiation effect, which is on the basis of developed and verified numerical thermal-fluid-structure coupling methodology under irradiation in Part I of this work. The mechanical deformation, thermal-hydraulic performance and Mises stress have been analyzed for the typical plate-type fuel assembly consisting of support plates under non-uniform irradiation. It was interesting to observe that: the plate-type fuel assembly including the fuel plates and support plates tended to bend towards the location with maximum fission rate; the hot spots in the fuel foil appeared at the location with maximum thickness increment; the maximum Mises stress of fuel foil was located at the adjacent location with the maximum plate thickness increment et al.

The purpose of this study is to gather baseline data on perceived housing values and satisfaction rates among consumers with the aim of using this information for future planning. Self-administered questionnaires were provided to 1000 university students from Gwangju and the Chonnam area from 2007 October 8th to 30th. The collected data was used to conduct comparative and descriptive statistical analysis: factor analysis, cluster analysis, t-test, $x^2-test$ and one-way ANOVA. The main findings are as follows: Firstly, in relation to perceived house values, students identified three factors as important: pursuit of convenience, disposition toward individuality-orientation and consciousness of others. The respondents regarded convenience as very important, especially in regard to one's safety, health and location of amenities. Secondly, cluster analysis based on perceived house value revealed passive and energetic types. Students in the energetic type exhibited a tendency to prefer convenience, independence, and consciousness of others. Finally in terms of housing satisfaction, the respondents identified four factors as important: house quality, neighborhood environment, local socio-psychological environment, and location. Housing satisfaction was higher among students who lived in large or new houses, shared the same house with their family, and had a room all to themselves. Accoding to these findings, university students important value safety, health and environmental-friendliness in a house and they find location important. Therefore, future houses should reflect these wants.

Objective : The authors attempted to confirm the risk factors for recurrent chronic subdural hematoma[CSDH] after simple burr-hole drainage. Methods : A total of 302 patients with CSDH who were treated at our hospital between January 1998 and May 2005 were studied. Various parameters considered for analysis of factors associated with CSDH recurrence; demographic and clinical findings [age, sex, history of seizures, diabetes, vascular diseases], initial and perioperative CT findings [hematoma density, location of catheter tip, post operative intracranial air, intracranial hematoma extension, hematoma width, hematoma site]. Results : Twenty-four patients [7.9%] experienced recurrence, whereas 278 patients [92.1%] did not. Five major risk factors should be considered : 1) layered type by hematoma density, 2) type I, II by location of catheter tip, 3) presence of postoperative intracranial air, 4) cranial base type of intracranial hematoma extension, 5) greater hematoma width. Conclusion : In this study, we report that the incidence of postoperative CSDH recurrence can be reduced by the examination of the hematoma characteristics on initial and perioperative CT findings and by preventing subdural air accumulation during operation. In addition, the location of the catheter tip can be used as a helpful factor in reducing the recurrence.

When the accident occurred in power distribution system, it needs to control efficiently the fault current according to the fault angle and location. The flux-lock type superconducting fault current limiters (SFCL) can quickly limit when the short circuit accidents occurred and be made the resistance after the fault current. The flux-lock type SFCL has a single triggering element, detects and limits the fault current at the same time regardless of the size of the fault current. However, it has a disadvantage that broken the superconductor element. If the flux-lock type SFCL has separated structure of the triggering element and the limiting element, when large fault current occurs, it can reduce the burden of power and control fault current to adjust impedance. In this paper, this system is composed by triggering element and limiting element to analyze operation of limiting current. When the fault current occurs, we analyzed the limiting and operating current characteristics of the two triggering current level, and the compensation characteristics of bus-voltage sag according to the fault angle and location.

This research aims to examine the characteristics of tomb sites including tomb mound and attached buildings and also to find out the principles reflected in the traditional oriental Feng-Shui location and spatial composition of Junkyung and Youngkyung tomb at Samcheok. The results of this study are as follows. These tombs harmonize with each other in the cosmic dual forces because Junkyung tomb is men's sex symbol and tiger to lie on his belly and Youngkyung tomb is women's sex symbol in geographical feature. Spatial structure in these tomb sites were placed in a reflected line following the hierarchy of metaphysics by standing high Geumchunkyo(Bridge)-Hongsalmun(Gate)-Jegak(Pavilion)-Bongbun(Tomb mound). Axis structure of these tombs is irregular bent-axis type from Geumchunkyo to Bongbun, specially in case of Youngkyung tomb it is getting more refractive. These tombs are divided into and characterized by three zones. Firstly the space for living people constitutes from Geumchunkyo to Hongsalmun, secondly the semi-sacred space constitutes from Hongsalmun to Jegak, and lastly the space for the dead constitutes from the back of Jegak to Bongbun. - type Jegak instead of T type Jegak generally used at Chosun Dynasty was installed because of claypan stretched out in front of Junkyung tomb and Bongbun of Youngkyung tomb located at a ravine between two mountain ranges.

We develop the success factors model including research hypotheses in the restaurant service industry. The research model in this study was tested on survey data collected from 282 restaurant owners. In this study, we tried to identify the success factors of the restaurant service industry and analyze the relationship between those success factors and business performance. Especially, we analyzed the impact of success factors on business performance being moderated by the restaurant type and location. Through the analysis of the research model, it is shown that operation management and customer relationship management and so on play an important role in the improvement of business performance. In addition, we found that the impact of the success factors on business performance is moderated by the restaurant type and location. A limitation of our study is the sampling. Franchise restaurants will need to be included in future studies. We expect that our research will help start-up restaurant managers to get useful insights to better manage their own businesses. Although the study on the success factors of the restaurant service industry is very important, there are few researches on that in Korea. Therefore, this study can give new insights on how the restaurant owners do business in the restaurant service industry.
