  • Human reliability assessment (HRA) is conducted on the unspoken premise that 'human error' is a meaningful concept and that it can be associated with individual actions. The basis for this assumption it found in the origin of HRA, as a necessary extension of PSA to account for the impact of failures emanating from human actions. Although it was natural to model HRA on PSA, a large number of studies have shown that the premises are wrong, specifically that human and technological functions cannot be decomposed in the same manner. The general experience from accident studies also indicates that action failures are a function of the context, and that it is the variability of the context rather than the 'human error probability' that is the much sought for signal. Accepting this will have significant consequences for the way in which HRA, and ultimately also PSA, should be pursued.

  • This study is to reveal the multi-generations' cohabitation and housing conditions are necessary for each generations to take over the homelike interchange as maintaining the excessive self-support. The subjects of this survey were 151 men and women over 60 years and older in Mokpo. The survey revealed that most or the people owned their own homes, and in many cases that the parents bought the home. There are many cases in which parents have been living with their own homes, and in many cases that the parents bought the home. There are many cases in which parents have been living with their children's families, since their children got married, and there many people who think that cohabitation is natural. In the aspect of living, the families normally eat together but there is a separation in economy and entertainment. There are many renovation and remodeling of a house to adjust the situation of three generations' cohabitation.About 70% of people experience problems with cohabitation. In particular, many cases involve the

  • Ground investigation data to be used as a basis for geotechnical analysis and foundation design are usually troubled with large uncertainty, due to natural variability and limited number of data. Statistical methods can be a rational tool for handling such uncertain ground data, in particular with a view to the selection of characteristic values for estimating ground design parameters used in design. The characteristic values of soil properties for use in geotechnical design have oftenly based on not only a subjective judgment but also engineer's past acumulated experience. This paper discussed some statistical methods which can handle such intrinsic ground uncertainty data with a case design in a rational manner.

  • The thermal system like a combustion chamber is believed to experience a significant instability problem with vibration in case that the thermal energy or the acoustic energy are transformed into a different form through a relevant path. This study deals with a numerically- predicted, Thermoacoustic instability in a Rijke tube by using a non-linear model for a heat source. The heating part where the energy transformation occurs actively is modeled after simulating two-dimensional cylinder case with constant surface temperature, and a nonlinear model that accounts for the transfer function of magnitude- and phase-characteristics is properly implemented so as to be dependent on the pulsation strength in the tube. The heat source model is observed to result in equivalent Thermoacoustic instabilities in the Rijke tube except low flow-rate cases in which the natural convection is dominant.

  • China is becoming a global hot topic because of its rapid economic growth. However, the country show signs of not meeting the expectation of retaining its long-term industrial competitiveness and economic growth, especially with a widening rich-poor gap and natural resource exhaustion. Realizing inclusive growth requires study of an inclusive innovation solution. In this paper, we analyze the feasibility and development path of China's inclusive innovation based on the framework of a National Innovation System, identify examples of inclusive innovation in China, and seek to provide policy suggestions for China's future sustainable development.

  • Parosteal osteosarcoma is characterized as a densely ossifying lesion, usually occurring on the surface near the metaphyses of a long bone. The histological pattern is a well- differentiated mature bone trabeculae with a hypocellular spindle-cell stroma. The cytological details are those of a low-grade malignant lesion. The natural history of this lesion is indolent local growth, late invasion of the underlying bone, and infrequently, distant metastasis. However, there is a significant risk of eventual dedifferentiation into a high-grade lesion. We report here-a case of parosteal osteosarcoma dedifferentiated into a high-grade lesion, which occurred in the left distal femur of a 40-years-old woman, and discuss the experience in detail.

  • This study was conducted to investigate the prevalence of obesity and the concerns with omega 3 fatty acid intakes in 100 men do regular exercising. Most subjects were 23~66 years old whose average height and weight were 170.0$\pm$0.5cm and 68.2$\pm$0.8kg, respectively. Prevalence of obesity was 7%, 41% and 41% by criteria of Bioelectrical impedance analysis, Skin fold thickness and Body mass index, respectively. According to this survey, 75% of the subjects prefered vegetable oil to animal fat, 55% of them prefered seaweeds to shellfishes and 76% of them prefered natural foods to processed foods for good health. 61% of the interviewed subjects had the experience of eating perilla oil and 49% of them chose the Mackeral that had contained omega 3 fatty acids. The reason that seaweeds were good for health was rather high vitamin and mineral content than low fat.

  • What is culture-products? Culture-products contains identity of nation and region. French critic Guy Sorman says "It is natural that buying culture-products when you travel any countries" Culture-products which contains our own cultural factors will give positive image of country. The research and development of grafting grudge experience culture-products was advanced the characteristic of area-culture that necessary is prerequisite. We need to develop culture-products which mixed regional culture and characteristic. We would like to research about Baekje culture and culture-products and sales products in museum. Museum is one of the tourist's attractions and great place to express regional factors. The culture-products are specially limited in the products which reflects a Baekje culture with Muryeong's tomb in Gong-ju and Baekje incense burner in Bu-Yeo it advanced. We hope that this research could help to understand market of culture-products and development.

  • These days we are more interested in the space of architecture that how the change is likely to affect and how to be realized human. Human beings are recognizable the space and the creation of the space is eventually effected through human beings being perceptible the space of architecture and the equivalence of the space. That is the light, one of phenomenological elements, has been the first visual experience at birth. This study will concentrate on the importance of the phenomenological light especially indoors and study how architectural elements influence human beings with the light as one of the basic design factors for human life. That is exactly purpose of this research paper and this paper can make our lives worth living significant with the actively various uses inside spaces through the phenomenological light as a natural light in our human beings.

  • The arid regions of western China are currently the focus of extensive exploration and development. This paper reports on recent experience gained by Chinese and Canadian project team members in the use of a variety of Earth observation satellite imagery for oil exploration and environmental assessment exercises in the Kuche area of Xinjiang. Through careful archival data selection and more recent data acquisition schemes, we have established several time series of MODIS, Landsat and Radarsat imagery in order to obtain a better understanding for daily, seasonal as well as decadal changes of the natural environment as well as man-made environmental features.
