This paper presents the performance characteristic of a Francis hydro turbine with an inline casing. This turbine is designed for city water supply system. Due to large changes in ground elevation with high points and low points, some systems may experience larger-than-normal required pressures in areas with low ground elevations. One way to dissipate these excess pressures is by the use of an inline-turbine instead of an inline-pressure reducing valve. For best applicability and minimal space consumption, the turbine is designed with an inline casing instead of the common spiral casing. As a characteristic of inline casing, the flow accesses to the runner in the radial direction, showing a low efficiency. The installation of vanes improves the internal flow and gives the positive encouragement to the output power. For the power transmission to the outside of the turbine casing from the runner axis, a belt passage is designed in the inline casing, as its influence, the region after the belt passage shows a relatively low output power. The clearance gap in the runner side space is considered, in which a small volume of flow is contracted into the clearance gap, forming the leakage flow. The leakage flow leads to a decrease in the efficiency.

This study provides the empirical testing to test the influences of contemporary leadership styles (i.e., transactional and transformational) on job satisfaction and customer satisfaction as the mediating variable between job satisfaction and customer loyalty. The approach utilized in this study was a quantitative research design using a survey model. The participants of this study were recruited from 160 front-liners in the airline's industry in Indonesia. This study employed 160 front liners (flight attendants, reservation/ticketing, and check-in-counter officers) who worked in Branch Office/General Sales Agent of Indonesian commercial airlines. The studied airlines serve domestic routes based at Soekarno-Hatta International Airport. Furthermore, the data were examined the four developed hypotheses by using Structural Equation Modeling (SEM). The primary results are: First, in the context of job satisfaction, both leadership styles (i.e., transactional and transformational) have similar influences; Second, job satisfaction affects customer satisfaction positively and significant, Third, customer loyalty is driven by passengers' satisfaction when they are utilizing the airline services. The findings imply that the working-role encouragement is essential to maximize the productivity of front-liners to serve their customer well. This research supports on developing the general knowledge based on leadership styles in the context of the airline's industry in managing the human resources strategically.

Purpose: The purpose of this study was to identify experiences of nurses who served as preceptors in clinical education for senior student nurses in a college of medicine in Wonju city. Method: Data was collected from 20 preceptors instructing senior student nurses in 2001 using a self-completion questionnaire. To analyze data, content analysis was done using an analysis scheme developed by the investigators. Result: The analysis scheme consisted of 7 categories and 25 subcategories. 135 significant statements were analyzed and categorized. Preceptors indicated that they were role models, socialization facilitators and educators while instructing students in the clinical practicum. In performing the preceptors' role, preceptors reported that their most important change was self-enhancement, and positive experience was a constructive work atmosphere. The most important factor facilitating the preceptors' role performance was support from head nurses, and the most discouraging factor was work loads. Conclusion: This study suggests that interventions for encouragement and socialization of preceptors should be developed to promote clinical education for senior student nurses.

There are two important trends in the modern information society, including digital networking and ubiquitous environment. Thus it is strongly required to develop new information storage devices such as high density storages to match the increased data capacity and small size storage devices to be applied to the mobile multimedia electronics. So far, many approaches have been studied for the high density memory, including the holographic memory, super-RENS and near-field recording using solid immersion lens (SIL) or nano-probe for the ODD (Optical Disk Drive) system, and the perpendicular magnetic recording and heat-assisted magnetic recording for the HDD (Hard Disk Drive) system. In addition, new mobile storage devices have been prepared using 0.85" HDD and 30mm ODD systems from a lot of foreign and domestic companies and institutes. In this paper, the recent technology trend for the next generation information storage system is summarized to offer a research motivation and encouragement to new researchers in this field with an emphasis on the technical issues of the increase of data capacity and decrease of device size.

This paper examined the effects of children's interests and attitudes toward mother's native culture and use of mother's native language on satisfaction of the mother-child relationship in multi-cultural families. Data from the 2012 National Survey of Multi-cultural Families demonstrate that for children aged between 9 and 12 years, their fluency and desire to speak well in the mother's native language as well as father's encouragement for using the mother's native language at home were positively associated with satisfaction of the mother-child relationship. For those aged between 13 and 18 years, mother's nationality (i.e. Southeast or South Asia) was negatively related with mother-child relationship satisfaction. Both mother's and children' communication skills, children's interests in mother's native culture, pride for mother being a foreigner, and desire to speak well in the mother's native language were positively associated with mother-child relationship satisfaction. Therefore, there is a need for foreign wives to be educated in Korean language and culture as well as opportunities for children to learn their mother's native culture and language.
