This study aims to empirically verify the impacts of job autonomy, job feedback and job manualization on the job satisfaction of the non-regular employees in a public corporation. For the empirical analysis, 163 non-regular employees(valid respondents) have been surveyed who are working in a public corporation. And the multiple regression analysis was used to statistically test the research hypotheses. The independent variables are 'job autonomy', 'job feedback', and 'job manualization'. The dependent variable is 'job satisfaction'. The results are as follows. The effects of 'job autonomy → job satisfaction(β=0.182, t=2.664, p<0.01)', 'job feedback → job satisfaction(β=0.208, t=2.927, p<0.01)' and 'job manualization → job satisfaction(β=0.397, t=5.785, p<0.01)' are all shown positive. Therefore, all the proposed hypotheses are accepted. From this result, we can get some lessons for the organizational management especially for the non-regular employees' job satisfaction. If you recognize that the non-regular workers are also valuable human resources for the company, it can be expected that strengthening the internal motivation of the employees through job enrichment such as autonomy, feedback, and manualization can positively influence the effectiveness of the organization.

잠수함이 가장 취약한 시기는 잠수함이 스노클이나 잠망경 운용을 위하여 잠망경 심도로 항해할 경우이며, 이때에는 비음향 탐지센서인 레이더와 광학, 사람에 의한 시각에 탐지될 확률이 매우 높다. 따라서 본 논문에서는 이러한 상황에서 탐지되는 취약성을 극복하고자 잠수함 마스트 및 잠망경 부분에 비음향 스텔스를 적용하고자 한다. 먼저 비음향 탐지센서에 대해서 조사하고, 그에 따른 스텔스 기법을 분야별 분석하여 최적화한 결과 다층형 구조로 선체표면부터 RAM layer, IR layer, Camouflage layer 구조로 각각 RAM layer는 자성재료인 페라이트계열로 3~5 mm, IR layer는 Ceramic 또는 Nickel 계열로 1~2 mm, Camouflage layer는 군청색 계열 페인팅을 제시하였다.

Olfactory receptors (ORs) detect volatile chemicals that lead to the initial perception of smell in the brain. The olfactory receptor (OR) is the first protein that recognizes odorants in the olfactory signal pathway and it is present in over 1,000 genes in mice. It is also the largest member of the G protein-coupled receptors (GPCRs). Most ORs are extensively expressed in the nasal olfactory epithelium where they perform the appropriate physiological functions that fit their location. However, recent whole-genome sequencing shows that ORs have been found outside of the olfactory system, suggesting that ORs may play an important role in the ectopic expression of non-chemosensory tissues. The ectopic expressions of ORs and their physiological functions have attracted more attention recently since MOR23 and testicular hOR17-4 have been found to be involved in skeletal muscle development, regeneration, and human sperm chemotaxis, respectively. When identifying additional expression profiles and functions of ORs in non-olfactory tissues, there are limitations posed by the small number of antibodies available for similar OR genes. This review presents the results of a research series that identifies ectopic expressions and functions of ORs in non-chemosensory tissues to provide insight into future research directions.

Sister chromatid exchange (SCE) has recently become a common cytogenic assay system for detecting exposure to chemical mutagens and carcinogens. One application of SCE is the monitoring of populations believed to have been exposed to such agents. A cross-sectional study of SCE frequency in peripheral blood lymphocytes from 45 Koreans aged 61 to 84 years was conducted. The effect of cigarette smoking and age on SCE was assessed by different degrees of smoking status such as smokers (n = 14), ex-smokers (n = 16) and non-smokers (n = 15). Mean spontaneous SCE per cell for the smokers (11.5 $\pm$ 1.1) was significantly higher (p < 0.05) than that for the non-smokers (8.8 $\pm$ 0.3). However, mean SCE frequencies per cell for the ex-smokers (10.3 $\pm$ 0.6) were not significantly different from those of the smokers or the non-smokers. The smokers showed an increased number of high SCE frequency cells (HFCs) when compared to the ex-smokers and non-smokers (p < 0.05). The mean SCE frequencies of the non-smokers showed a statistically significant increase (p < 0.05) with the subject's age. These results show that age and smoking habits contribute a great deal in setting a higher degree of basal DNA damage in elderly Koreans, and smoking appeared to be a more significant damaging factor than age.

Recently, there has been growing interest in barrier-free design which makes safe and convenient space for every pedestrian, not only the non-disabled but also the disabled. The purpose of this study is to suggest the data on the pavement materials of barrier-free pedestrian environment in view of universal design. In order to this, the research is focused on evaluating the visual preference and preference factors for pavement scenery, which can be changed by pavement materials. And this research is also comparing the visual preference and preference factors of the disabled with that of the non-disabled. A multi-regression analysis method is adopted to analyse the correlation between the visual preference for pavement scenery and preference factors in this study. The result of this analysis is as follows. Firstly, there are some differences of visual preference for the pavement material between the disabled and the non-disabled. Secondly, independent variables influencing on preference are similar between two groups. Thirdly, there are some differences in the priority of preference between the disabled and the non-disabled. This study will contribute to the field of barrier-free design and sustainable development projects in order to maximize the human being's satisfaction.

In the face of the new dimension of the developed technology $L{\acute{a}}szl{\acute{o}}$ Moholy-Nagy, a master of 'the Bauhaus Akademie', made an effort to constitute the integrated life of the intellectual and the emotional by translating the experiences of the new technology Into the emotional language and the cultural realities. As an artist who criticized in the constructivist ethos the conception of the image as the imitation and brought the Image movements into relief Moholy-Nagy groped for a new expressive idea that can be called as 'the idea of the non-representational spatial expression' in which the expressive elements interact one another. His idea of the non-representational spatial expression that is made up of the pure forms of the nature, the direct colors and the spatial elements is oriented to incorporate the modern realities, i.e. the space experiences as the complicated sensory workings and the new technology as the measure of the human thinking, and further to see where they will move to. This study is on the one hand purposed to explicate the fundamental idea of the non-representational spatial expression that was poorly illuminated in spite of its importance in the respects of the design and art history, on the other to re-actualize the implications of the space-design which are contained in it.

Religion is deeply connected with human culture and life, and affects all areas of religious people's lives. The aim of this study was to find out how fashion-conservativeness of religious people and non-religious people differ in Korea. Ten religious people and ten atheists all in their twenties were interviewed to find out the differences between religious people and non-religious people related to their viewpoints on clothes. The twenties age group was selected because people in their twenties are sensitive to fashions and styles, and a fair proportion of males and females were selected. The subjects were asked demographic questions, questions about their religion and faith, whether or not they thought they were conservative or affected by religion, and finally, what they thought of photographs of certain styles. 12 photographs from the 2006-7 F/W collections of London, Paris, New York and Milan were presented to the subjects. The photographs were from the Vogue U.K. website and divided into 6 major styles based on verbal evidence used to describe the collections in catwalk reports: "Sexy," "attitude/confidence," "luxury," "sophisticated/chic," "feminine," and "rock." In conclusion, religious people were found to be more conservative than non-religious people in their twenties because they prefer more conservative and covered up styles, have more negative views of bold and skin-showing trends, and regard some styles to be too sexy when non-religious people do not.

Purpose: The purpose of this study was to investigate the therapeutic effect of non-invasive vagus nerve stimulation by transcutaneous electrical nerve stimulation application on the autonomic nervous system of human body. Methods: Participants were seventeen healthy adults. Standard deviation of all normal N-N intervals(SDNN), root mean square of successive differences(RMSSD), low frequency(LF), high frequency(HF) were compared in pre and post Mean values after intervention. Data were analyzed in Wilcoxon's signed-ranks test. Results: The results of this study is that sistolic blood pressure and pulse rate decreased mean value after non-invasive vagus nerve stimulation by transcutaneous electrical nerve stimulation. High frequency, low frequency, SDNN, RMSSD increased mean value in heart rate variability after intervention. But that is not significant except for SDNN. Conclusion: Non-invasive vagus stimulation by transcutaneous electrical nerve stimulation effect on parasympathetic nerve stimulation, and then it might be effective method for autonomic nerve balance control.
