Personal Air Vehicle is expected to be a promising solution to relieve traffic congestion using urban airspace. The development of related technologies such as materials or batteries has been accelerated. In addition, commercial transportation services are being prepared. When fierce competition begins in the PAV market, even technologically superior products will disappear without choices by consumers. Therefore, demand factors should be reflected in PAV development to enhance competitiveness. In the paper, values were estimated for the major technological attributes of PAV. Stated preference data were collected through a survey, and the conjoint method and ordered probit model were adopted. Thereafter, it was confirmed that the value would be high in the order of dual mode, drone-type appearance, and noise reduction. Some R&D strategies were proposed based on this.

Globalization and the emergence of new markets has placed increased emphasis on cross-cultural sales and marketing research. Despite considerable advances in the personal selling literature, little is known about the cross-cultural transferability of key constructs. Given the degree to which well-accepted relational sales behaviors such as ASB and customer oriented selling reflect Western values such as individualism and low uncertainty avoidance, the relative efficacy of such practices in alternative cultural context is less clear. Using a Korean sample, our results confirm the beneficial direct effects of these relational selling practices upon performance. However, we also find strong workgroup interdependence diminishes the effects of ASB and that performance fully mediates the relationship between both sales behaviors and job satisfaction. In contrast to prior results, we find female salespeople and those newer to their position demonstrate stronger ASB.

In this paper, focusing on Oscar Wilde's novel "The Picture of Dorian Gray," we explore the protagonist's lack of conscience and unethical attitude, emphasizing its relevance to our self-development and growth. The primary goal is to interpret the impact of Dorian Gray's actions and choices on personal development and growth, highlighting the importance of a specific mindset and attitude to the reader. It dissects how Wilde navigates the intricate layers of Dorian's character, exposing the ethical dilemmas and transformative moments that contribute to the profound changes within him. The examination sheds light on the depth and complexity of Dorian Gray's character, offering readers a nuanced understanding of the forces at play in his moral and psychological journey. Interpretation of Wilde's intent to impart lessons on the reader's personal growth and development through Dorian's story is undertaken. The discussion also explores the impact of Dorian's unethical attitude on contemporary readers and its influence on our daily lives and values.

This study is to provide the basic sources to develop educational data that can establish ethical values with research on the interrelation between moral development and ethical values of nurses. The subjects of this study are the convenience sample from 111 nurses working in clinical settings from 5 general hospitals located in Pusan area. The questionnairs for this study are comprised two parts: Part 1 is SRM-SF(1995) guestionnaire, and translated by Kil, 1m Ju(1997): Part 2 is the guestion papers about the ethical values, and disigned by Jung, Hee Ja. The data were collected from June lth to 31th, 1997 and analyzed by S.A.S(Statistical Analysis System) Package for frequency, percent, and Pearson's correlation coefficient. The results of the study is as the followings: 1) According to the moral development. the nurses are in the levels of Stage3 or Transition3/4, which are generally focused on the personal relations or personality. Thus, nurses are considered to need to get the stage4 of education that helps them recognize a person as a member of society. a family as an unit of society, and human life as the values of human dignity. 2) According to the ethical values, nurses have the positive ethical values of respecting the right of the patients, providing information, keeping the secret, truth. and credit of patients. But they also experience some troubles by the patients to care and the clinical situation. Thus, to overcome the problems, nurses are considered to need to get the education that establishs the right ethical values. 3) The analysis result on the interrelation between moral development level and ethical values shows as r=0.28 and p=0.003. This indicates that the interrelation between them is low. In conclusion, it is considered that the moral development level is viewed broadly from a person and family to a society, and then it can affect to the ethical values positively.

Despite the recent emphasis on value research in mathematics education along with the significance of values from a new perspective, there has been a lack of research on the values perceived by teachers and students in Korea. This paper analyzes how fifth-grade students would perceive the values of a master teacher with expertise in elementary mathematics education after her teaching of mathematics and whether their values on mathematics learning would change. According to the study, the students recognized that the master teacher valued understanding, preview-review, picture, problem, and reason in mathematics learning. Among these, the value of understanding was perceived as the core value. An analysis of the students' values on general mathematics learning and personal mathematics learning showed that preview and review were the most important before and after the master teachers' teaching. An analysis of the changes in the values of students showed the greatest change in the value of understanding. Instead of accepting the values of the master teacher as it were, students actively reconstructed and maintained them. Based on these results, this paper has drawn implications regarding the consideration of students' values in mathematics learning.

Objectives: The aim of this study is to evaluate exposure levels of the extremely low frequency magnetic fields(ELF-MF) radiated from various electric facilities in Liquid Crystal Display(LCD) manufacturing processes. Methods: This study measured the exposure levels of personal and local ELF-MF for the electronic facilities installed in two LCD manufacturing companies. Samplers were installed around workers' waist during working hours to identify personal exposure levels, and direct reading equipment were located at 3 cm, 10 cm, and 30 cm away from the surface of the electronic facilities to measure local exposure levels. Average and maximum(ceiling) values were calculated for personal and local exposure levels. Results: Average and maximum of personal exposure levels for each worker were 0.56(mean) ± 0.02(SE) µT and 6.31 ± 0.75 µT, respectively. Statistical analyses of the study found that maximum of the personal exposure levels for engineers was significantly higher than that for operators since engineers spend more time near the electronic facilities for repairing. The range of maximum personal exposure levels was 0.50 ~ 43.50 µT and its highest level was equivalent to 4.35 % of ACGIH(American Conference of Governmental Industrial Hygienists) exposure limit value(1 mT). Maximum of local exposure levels was 8.18 ± 0.52 µT and the electronic facilities with higher exposure levels were roof rail and electric panel, which were not related to direct manufacturing. The range of maximum local exposure levels was 0.60 ~ 287.20 µT and its highest level was equivalent to 28.7 % of the ACGIH exposure limit value. Lastly, the local exposure levels significantly decreased as the measurement distance from the electronic facilities increased. Conclusions: Maximum of personal and local exposure levels did not exceed the exposure limit value of ACGIH. However, it is recommended to keep the workers as far as possible from the sources of ELF-MF.

Williams, M K., King, E., and Walford, Joan (1969). Brit. J. industr. Med., 26, 202-216. An investigation of lead absorption in an electric accumulator factory with the use of personal samplers. Thirty-nine lead workers and controls, in stable conditions of exposure, each wore personal lead-in-air samplers daily for two weeks. During the second week samples for blood lead, urinary lead, urinary coproporphyrin, urinary $\gamma$-aminolevulinic acid (ALA), the punctate basophil count, and haemoglobin were taken daily. Duplicate estimations were made on one day. The lead exposures of men doing almost identical jobs differed by ratios of up to four to one. This could be attributed on y to personal differences in working habits. The correlation coefficients and regression equations of the biochemical tests with lead-in-air and with each other were determined. The mean values and $95\%$ confidence limits of single determinations of some of the biochemical tests corresponding to the two commonly accepted TLVs of lead-in-air (0-20 and 0-15 mg./$m^{3}$) were calculated from the regression equations. For each biochemical test the variation due to analytical error, the variation from day to day within subjects and the residual variation about the regression on lead-in-air were calculated. Previous estimates of the latter are not known. Excessive confidence may be placed in an index of exposure due to its low coefficient of variation within subjects unless the coefficient of variation between subjects about regression is taken into account. The correction for specific gravity of estimations of lead and ALA in spot samples of urine was found to reduce slightly the residual variation between subjects about the regression on lead-in-air and to increase the correlations with lead-in-air and with the other biochemical tests, but these changes were not statistically significant. The modified method used for estimating blood lead and urinary lead is described and validated.
