This study was made to identify species of archaeological wood products excavated from three sites(Kwunbuk-ni, Gungnamgi, Wanggung-ni) of Sabi Era, Baekje. These sitesare presumably considered as capital areas of Sabi Era, Baekje. Total of 220 specimens were identified into five softwoods and eighteen hardwoods. Pinus densiflora(or Pinusthunbergii) and Quercus spp. are the most common and occupied 32%, 28% of totalspecimen, respectively. The others are follows : Torreya nucifera(1%), Abiesholophylla(3%), Cryptomeria japonica(4%), Thuja spp.(2%), Chamaecyparisobutusa(2%), Salix spp.(1%), Platycarya strobilacea (3%), Alnus spp.(1%), Carpinusspp.(0.5%), Castanea crenata(9%), Zelkova serrata (6%), Celtis spp.(0.5%), Prunusspp.(2%), Rhus verniciflua(1%), Rhus trichocarpa(0.5%), Meliosma oldhamii(1%),Hovenia dulcis(1%), Kalopanax pictus(0.5%), Cornus walteri(0.5%), Styrax japonica(1%),Fraxinus rhynchophylla (0.5%), F. sieboldiana(1%).Most of the identified species have been growing in this area until nowadays. However,a few species(Cryptomeria japonica, Thuja spp. Chamaecyparis obutusa, Torreyanucifera) didn’t grow natively around this area at that time. Two species(Cryptomeriajaponica, Chamaecyparis obutusa) are endemic species of Japan, indicating international trade or exchange of woods between Baekje Kingdom and Japan in 6-7th century. Torreyanucifera grows in limited areas in Korea (south of $35^{\circ}$10′N), however, is widely distributed in the southern Japan. Quercus spp. was identified the most in implements of Baekje and Pinus densiflora(orPinus thunbergii) was in the second place. Zelkova serrata was mainly used for raw materials of turnery products, e.g., wooden container. This species produces one of the hardest woods as 0.7 in specific gravity. It indicates that iron technologies have reached some high level in Sabi Era, Beakje.

This study intended to identify regional and gender differences between high school students groups in clothing-wearing motives, casual brand preference and actual purchasing condition. Using a $2{\times}2$ sampling frame, 100 responses were collected for each regional and gender group: male students in Seoul, females in Seoul, males in Gumi, and females in Gumi. In terms of clothing-wearing motives, Gumi students and female students showed more highly extroverted motives than males and Seoul students, respectively. And three groups were determined on the basis of clothing-wearing motives: the extroversion group, the introversion group, and the least clothing-cognizing group. Concerning the brand preference factor, female students showed more dispersed brand preference than males. Adidas and Puma were preferred by all 4 groups. Polo and Guess were preferred by Seoul students, and Clide, Banila B, and TBJ were preferred by female students. The determinants of brand preference were identified as quality, reliability, affirmative image, and some brand personas such as 'neat', 'natural' and 'polished'. The students from Seoul tend to pay more money for clothing than those from Gumi, and Seoul students' main purchasing place was identified as department store while Gumi students shop more at brand chain stores.

Generally, Permanent Magnet Brushless DC Motor(PM BLDC) is necessary the Hall-IC to detect the rotor position. But it will take place the operation standstill of motor or error of rotor position detection according to the circumference temperature, humidity, or limited surroundings. This paper propose the algorithm of rotor position detection only using one or two Hall-IC. Therefore we can estimate information of the others phase in sequence through a rotor instead of using three Hall-IC at 3 phase motor. This paper identify the same characteristics, performance and function of protection circuit by the proposed algorithm with the 3 phase PM BLDC motor in comparison with general method.

In this study, the fire risk of the curtain wall structure was compared with a general structure among the double envelope structure using a fire simulation program. To this end, a fire-story building curtain wall was modeled as virtual using the PyroSim based on a fire simulation program (FDS). And then, the fires occurred in the model, divided by curtain wall non-applied model and applied model, in the same structure and place. To identify the fire characteristics, smoke behavior characteristics, viewing distance, and volume fractions of CO and $CO_2$ were comparative analyzed. As a result, it was identified that the curtain wall applied model quickly filled with smoke from the top floor to under the floor compared to the curtain wall non-applied model. From this study, the fire risk of curtain wall structure was evaluated in detail using the fire simulations.

The appearance and evolution of cloud service is potentially one of the major advances in information and communication technology. However, it is necessary to identify and understand the various issues of cloud service, both from the perspectives of the providers and the consumers of it. While a lot of studies such as cloud business model, profit model and technology itself are currently taking place in cloud service considering provider's aspects, there are a few researches dealing with cloud service user's aspects. This paper presents the user behavior analysis focused on SaaS users and discusses the development strategy of SaaS service based on the results of user behavior analysis. In order to analyze the user behavior, we surveyed SaaS users divided into two groups such as present and future user groups. Eventually, we proposed the SaaS prospects, development strategy and policy issues based on user behavior analysis.

Background: Breast cancer is the most common cancer and the second most common cause of cancer-induced mortalities in Iranian women, following gastric carcinoma. The survival of these patients depends on several factors, which are very important to identify in order to understand the natural history of the disease. Materials and Methods: In this retrospective study, 313 consecutive women with pathologically-proven diagnosis of breast cancer who had been treated during a seven-year period (January 2006 until March 2014) at Towhid hospital, Sanandaj city, Kurdistan province of Iran, were recruited. The Kaplan-Meier method was used for data analysis, and finally those factors that showed significant association on univariate analysis were entered in a Cox regression model. Results: the mean age of patients was $46.10{\pm}10.81$ years. Based on Kaplan-Meier method median of survival time was 81 months and 5 year survival rate was $75%{\pm}0.43$. Tumor metastasis (HR=9.06, p=0.0001), relapse (HR=3.20, p=0.001), clinical stage of cancer (HR=2.30, p=0.03) and place of metastasis (p=0.0001) had significant associations with the survival rate variation. Patients with tumor metastasis had the lowest five-year survival rate (37%)and among them patients who had brain metastasis were in the worst condition (5 year survival rate= $11%{\pm}0.10$). Conclusions: Our findings support the observation that those women with higher stages of breast malignancies (especially with metastatic cancer) have less chance of surviving the disease. Furthermore, screening programs and early detection of breast cancer may help to increase the survival of those women who are at risk of breast cancer.

The aim of this study is to identify the floor plan types of folk houses or traditional vernacular dwellings found in Nagan Folk Village located in Joellanamdo province. Examining the floor plans appeared among 36 vernacular folk houses presumably built in the 19th century in the village by means of the changes in the number of bays of Anche, the mail block of the house, the study was also able to construct a spatial compositional process of floor plan development. The floor plan examination revealed that the basic floor plan type in Nagan folk housing was '一' shape, a typical southern dwelling based on the existing classification. This basic type is consisted of three bays or rooms: Jeongji (kitchen), Anbang (large room), and Jageunbang (small room). New spaces or rooms are added to this three room house to expand the house as the residential functions become more complex, such as more living and storage spaces. The expansion appears to have two direction. On the one hand, it has been taken place by inserting Marea, an open wooden floor living space between Anbang and Jageunbang to meet the extended living demand. On the other, Jeongjibang, a second kitchen/storage has been attached to Jeongji outward for extra cooking and storage. This two-way expansion shows the trend of symmetric expansion between cooking, storing space and dwelling space. It can be implied that the arrangement of house rooms has been structurally formulated and shared by the farmer-builders in the 19th century in Nagan village who appeared to be influenced by fixed images for housing.
