The aim of this study is twofold. First, this study aimed to explore how Korean university students' English learning motivation is related to their English listening proficiency and study time. Second, it attempted to interpret the English learning motivation linking the two different motivation theories: self-determination theory and L2 motivational self system. The constructs of the students' L2 learning motivation were investigated with the data obtained through the questionnaire from 122 sophomore students. A factor analysis was conducted to extract the major factors of motivation. As a result, 6 factors were extracted: Intrinsic Pleasure, Identified Value Regulation, Intrinsic Accomplishment, Introjected Regulation, External Regulation, and Identified Regulation. The Interrelatedness among the assessment results on the L2 listening proficiency (pre and post test), listening study time, and motivation factors was measured by correlation coefficients. The statistical results indicated that pre-test scores were significantly related to Identified Regulation and Identified Value Regulation toward English learning, and post-test results had significant correlation with Intrinsic Accomplishment and Identified Regulation. However, no motivation subtypes showed statistical association with the students' listening study time. The results were attempted to be interpreted both under L2 motivational self system and self-determination framework to better illuminate the motivation theory with more explanatory power.

The purpose of this study was to explore and analyse the work value of university students majoring in health care management. The subjects of this study were 300 students. Maryland Work Value Inventory was used and the data were collected using a structured and self-administrated questionnaire. As a result of factor analysis, the following results were obtained. First, the work value consists of six factors (financial remuneration, social status, social contribution, capability, achievement, proper pride) and it can be classified extrinsic work value (financial remuneration, social status) and intrinsic work value(social contribution, capability, achievement, proper pride). Second, The mean extrinsic work value(4.16) was higher than the mean intrinsic work value(3.80). The preference order of the work value was like this; financial remuneration(4.36) the first, achievement(4.05), social status(3.96), proper pride(3.93), capability(3.78), and social contribution(3.45) the last. Third, the mean of the economic stability in extrinsic work value was the highest. The factors meaningfully relating with intrinsic work value were age, school grade and the experience of job. Forth, as a result of regression analysis, the more school grade they have, the less extrinsic work value and the less their mother's level of education, the higher extrinsic work value.

In today's rapidly changing environment, companies need to have proper strategies in place to meet the challenges that constant change presents. Being flexible, responding and adapting to changes can be valuable. However, they are essentially passive ways of dealing with situations. Creating new values and innovation are more active and effective strategies fora constantly changing environment. As such, most companies in e-business should focus on developing creativity across the board. Employees' creativity has become a critical factor in e-business. This paper explains how to increase workers' creativity through authentic leadership and psychological empowerment. As it is not machines or computers, but people, that are ultimately still responsible for creating novel outcomes, this study emphasizes the overriding importance of members' ability and leader's roles, which greatly influence followers' levels of motivation. Authentic leadership encourages members to reach and display their potential, and enhances their intrinsic motivation. Moreover, members' psychological empowerment is directly associated with both intrinsic motivation and autonomy, preconditions for creativity. Hence, these two dimensions- leadership and an individual's psychological state- will increase workers' creativity, which works to increase performance and create more opportunities not only at the individual level, but also at the team or organization level. The purpose of this paper is to explain the effects of authentic leadership on creativity and the moderating effects of psychological empowerment between authentic leadership and creativity in the e-business environment.

Jets of compact radio sources are highly relativistic and Doppler boosted, making studies of their intrinsic properties difficult. Observed brightness temperatures can be used to study the intrinsic physical properties of the relativistic jets. The intrinsic properties of relativistic jets depend on inner jet models. We aimed to observationally test the inner jet models. The very long baseline interferometry (VLBI) cores of compact radio sources are optically thick at a given frequency. The distance of the core from the central engine is inversely proportional to the frequency. Under the equipartition condition between the magnetic field energy and particle energy densities, the absolute distance of the VLBI core can be predicted. We compiled the brightness temperatures of VLBI cores at various radio frequencies of 2, 8, 15, and 86~GHz. The brightness temperatures in the rest frame were investigated in the sub-parsec regions of the compact radio sources. From the vicinity of the central engine, the brightness temperatures increased slowly and then rose with steeper slope, indicating that the Lorentz factor increases along the jet. This implies that the jets are accelerated in the (sub-)parsec regions from the central engine.

Purpose - Based on previous studies, this study extends current research and investigates whether the sub-factors of emotional intelligence increase job satisfaction or employee intrinsic and extrinsic motivation and perceived organizational support. Research design, data, and methodology - This study categorizes service employees' (consultants) emotional intelligence into four sub-factors: regulation of emotion, appraisal of emotion, utilization of emotion, and expression of emotion. The study then investigates the sub-factor effects on job satisfaction. A total of 353 valid questionnaires were collected. Results - The results of the path analysis showed that appraisal, utilization, and expression of emotion had a positive effect on intrinsic motivation, and utilization of emotion had a positive effect on extrinsic motivation. Extrinsic motivation had a positive effect on perceived organizational support and job satisfaction, and perceived organizational support had a positive effect on job satisfaction. Conclusion - As consultants' utilization of emotion is rendered as the ability to use emotion to improve performance, the conclusion is that such factors as monetary performance incentives are important in order to boost job satisfaction of the consultants.

Material corrosion in nuclear power plant (NPP) is not controlled only by amine injection but also by ion exchange (IX) which is the best option to remove trace Na⁺. This study was conducted to understand the Na⁺ leakage characteristics of IX beds packed with ethanolamine-form (ETAH-form) and hydrogen-form (H-form) resins in the simulated water-steam cycle in terms of intrinsic behaviors of four kinds of cation-exchange resins through ASTM test and Vanselow mass action modeling. Na⁺ was inappreciably escaped throughout the channel created in resin layer. Na⁺ leakage from IX bed was non-linearly raised because of its decreasing selectivity with increasing Na⁺ capture and with increasing the fraction of ETAH-form resin. Na⁺ did not reach the breakthrough earlier than ETAH⁺ and NH₄⁺ due to the increased selectivity of Na⁺ to the cation-exchange resin (H⁺ < ETAH⁺ < NH₄⁺ ≪ Na⁺) at the feed composition. Na⁺ leakage from the resin bed filled with small particles was decreased due to the enhanced dynamic IX processes, regardless of its low selectivity. Thus, the particle size is a predominant factor among intrinsic properties of IX resin to reduce Na⁺ leakage from the condensate polishing plant (CPP) in NPPs.

In this paper, optimal deep reactive ion etching (DRIE) process conditions for fused quartz were experimentally determined by Taguchi method, and fused quartz-based micro cantilevers were fabricated. In addition, comparative study on Q-factors of fused quartz and silicon micro cantilevers was performed. Using a silicon layer as an etch mask for fused quartz DRIE process, different 9 flow rate conditions of $C_4F_8$, $O_2$ and He gases were tested and the optimum combination of these factors was estimated. Micro cantilevers based on fused quartz were fabricated from this optimal DRIE condition. Through conventional silicon DRIE process, single-crystalline silicon micro cantilevers whose dimensions were similar to those of quartz cantilevers were also fabricated. Mechanical Q-factors were calculated to compare intrinsic damping properties of those two materials. Resonant frequencies and Q-factors were measured for the cantilevers having fixed widths and thicknesses and different lengths. The Q-factors were in a range of 64,000 - 108,000 for fused quartz cantilevers and 31,000 - 35,000 for silicon cantilevers. The experimental results supported that fused quartz had a good intrinsic damping property compared to that of single crystalline silicon.
