  • In this work wood crib burning behaviors have been simulated by using the FDS(Fire Dynamic Simulator) program. Wood cribs are regularly stacked arrays of wood sticks, and available for the performance rating of fire-extinguishers. On the basis of an angle iron supporter 26 layers of wood sticks have been stacked up. Each layer consists of 5 or 6 wood sticks which are placed in parallel, with a constant distance, and in alternating rows. They are laid between the horizontally adjacent sticks at the before last layer. The wood crib is ignited instantaneously by an amount of burning gasoline below. A comprehensive simulation of such a practical sophisticated combustion is still too difficult to realize with any currently available computer, although the performance of modern processors is getting better everyday. We could carry it out here through parallel computing on the HPC(High Performance Computing) cluster as the feasible alternative. At last the validation has been executed by means of temperature distribution data measured by the thermal video camera.

  • Purpose: This study was done to identify predictors of the fighting spirit or helplessness/hopelessness in the patients' mental adjustment to cancer. Cancer patients' characteristics like performance status, metastasis and duration of diagnosis with demographic factors, spiritual support and social support were used as predictors of a fighting spirit or helplessness/hopelessness. Methods: A total of 124 ambulatory cancer patients completed the Mental Adjustment to Cancer (MAC) scale and responded in a structured instrument about their characteristics, spiritual and social support. Results: The results of multiple regression analysis revealed that confidence in the supporter ($R^2=.114$, p=.000), duration of cancer diagnosis ($R^2=.041$, p=.000) and faith ($R^2=.030$, p=.000) were predictive of a fighting spirit ($R^2=.185$, p=.000); whereas, education ($R^2= .074$, p=.001), performance status ($R^2=.055$, p=.000), satisfaction with social support ($R^2=.046$, p=.000), and metastasis ($R^2=.037$, p=.000) were predictive of helplessness/hopelessness ($R^2=.202$, p=.000). Conclusion: Social support, spiritual support and disease related factors like metastasis, performance status, and duration of cancer diagnosis need to be considered in a psychosocial nursing intervention for a fighting spirit or helplessness/hopelessness.

  • The number of North Korean refugees residing in the Republic of Korea (South) has reached 17,000, and this number is expected to exceed 20,000 (North Korean Supporter's Association, 2009). Refugees have developed improper dietary habits while hiding and escaping North Korea. They have also developed preferences for exotic food. This thesis attempts determine the changes in Korean food. This study also describes the view on South Korean food by North Korean refugees. According to our survey, women refugees had better dietary habits than men. Moreover, women and those in their 40's showed a tendency to choose food based on quality over quantity. Both men and women refugees responded that they cook food based on North Korean recipes. Those who view their current financial status as average or higher stated that South Korean food is tastier than North Korean food. Those whose financial status among North Koreans was average or higher when they lived in North Korea appreciated the splendor and beauty of South Korean food more. The results of this study are expected to assist in determining the differences in dietary habits between those from the North compared to Koreans living in the Republic of Korea. Therefore, studies between South and North Korean food should continue.

구르나 프로젝트에 나타난 하싼 화티의 건축과 정기용의 건축에 관한 비교 고찰 -하싼 화티 저(著)·정기용 역(譯) 『이집트 구르나 마을 이야기』의 영향관계를 매개로- (A Comparative Study of Hassan Fathy's Architecture Shown in Gourna Project and Chung Guyon's Architecture -through the Intermediation of Gourna: A Tale of Two Villages, Written by Fathy and Translated into Korean by Chung-)

  • The Korean architect Chung Guyon(1945~2011) is the translator of the Korean edition of Gourna: A Tale of Two Villages(1969) written by the Egyptian architect Hassan Fathy(1900~89). This fact, along with the facts that Chung changed the topic of his graduation thesis(1983) for UPA no.6 in Paris and that he became a supporter of earth architecture after he returned to Korea in 1986, confirms that Chung was strongly influenced by Fathy's architecture in Gourna project. Therefore, the present paper aims at extracting didactic characteristics of Fathy's architecture from the book and comparing them with those of Chung's architecture. The categories of the characteristics extracted from the book (or his architectural activities in the Gourna project) are: clay/earth architecture; communicative and cooperative architecture; and critical stance towards society, and these are commonly found in Chung's architecture, too, not without differences from Fathy's owing to the gap between the two architects' contexts. Reviewing these characteristics, this paper argues that Fathy and Chung tried to improve society in each context, working as both architect and social activist.

  • As the importance of R&D has recently become more important, the budget for national R&D projects has continued to grow. Along with, there is a growing awareness to use and manage R&D funds transparently. This study examines the relationship among attitude toward the behavior (ATT), subjective norm (SN), perceived behavioral control (PBC) and behavioral Intention (BI) deriving from TPB (Theory of planned Behavior). To empirically prove the hypothesis, the statistical analysis were conducted based on the response from the 2,021 RCMS users, using SPSS 21.0 and AMOS 21.0. The research model variable consists of ATT, SN, PBC, BI, person type, RCMS characteristics. The results of study can be summarized as follows. First, ATT, SN, PBC have the positive effect on BI. Second, According to the type of person (Director, R&D supporter), there is no difference in ATT on BI but there is a difference in SN (or PBC) on BI. Third, The type of person have moderating effects in the relationship between ATT and BI. Finally, All RCMS characteristics have moderating effects in the relationship between ATT and BI. Some RCMS characteristics have moderating effects in the relationship between PBC and BI.

  • Purpose: To examine the relationships among loneliness, social support, and family function in elderly Korean. Method: The sample for this study were 290 elderly Korean who were at least 60 years of age. Data were collected by interview using the translated Korean versions of the Revised University of California Los Angels Loneliness Scale(RULS), Family APGAR, and Social Support Questionnaire 6. Result: Subjects were moderately lonely and had moderately functional families. Means for social support were 1.42 for network size and 4.09 for satisfaction. Subjects who lived with their spouses had a larger number of network members than who did not live with spouses. However, living with spouses was not associated with social support satisfaction. The level of loneliness was related negatively to the level of social support network, social support satisfaction and family function in this study. Social support satisfaction and Family function were the significant predictor of loneliness. Conclusion: The number of social supporter and satisfaction and family function should be considered in nursing intervention to decrease the level of loneliness in older adults. Further studies and efforts will be needed to reduce the level of loneliness in older adults.

  • The behaviour of pressure vessel made of SS41 steel was investigated during hydrotest. AE tests were carried out for the vessels in as-manufactured, V-notched and weld-cracked state using microcomputer-based AE instrumentation. The following results were obtained: 1) In the case of source location using cylindrical program, to minimize the error of source location, the difference of max. Delta T values measured from each sensor should be kept as small as possible. 2) When crack grew, AE event rate increased continuously but AE event from the inclusions occurred intermittently, so by analyzing event rate, the source of AE could be derived. 3) From the spot welding part of supporter, many events with low energy occurred independent of Kaiser effect, which could be confirmed by analyzing energy parameter. 4) The b-value from the tensile specimen of was lower than that from normal specimen and the b-value from crack propagation was lower than that from deformation, so by analyzing peak amplitude distribution, the source mechanism could be derived from the b-value.
