  • Recently, developments of engineering technology are too fast change to educate the students in the college of engineering. The lag between the innovation of the technology and the education of the college of engineering becomes larger and larger. In this situation, the appropriate education update system is needed to change the curricula for the updated engineering education. In this paper, the job analysis method which is used in the technical service area is transformed to design the curriculum of the general higher education area. The job analysis method which is used in the technical service area derives the competence too detail and complex to used in the higher education area. for the higher education area, the social activity analysis of the alumni is needed to extract the representative jobs of the area. Also using this representative jobs, the job analysis and competence derivation is conducted. If needed, the regular expert meeting is held to converge the job-site opinions of the graduate and industry people. This curriculum changing process is provided as a part of the circular self-improve education system of the Electrical Engineering of the MyongJi University.

  • Due to the sustained increase in lifts expectancy, the number and proportion of the aged population has substantially increased, the proportion of the total population aged 65 and over was 7.1% in 2000 and 14.3% in 2022. But All public pension schemes in Korea, including the National Pension scheme, civil servants pension scheme, private school teachers pension scheme and the military pension scheme, are facing valving degree of financial problems at present because of their weak and unstable financial bases. with the result that some of them have recorded deficits for some time and the others are expected to run deficits in the near future. This crisis in financial sustainability in public pension schemes is attributable to the structural weakness of the schemes which can be characterized as high benefits, low contribution. Therefore, this article focuses on alternative of public pension schemes reform in Korea. The results is as follows. First, a basic pension is proposed to be newly established and the earnings related portion of National Pension Scheme will be as national pension. Secondly, the Basic Pension is a universal basic pension covering all nationals over 18 years and older, thereby achieving \"one pension for everybody\" Thirdly, National Pension will be operated as an earnings related pension covering only those participants with assessed income. Fourth1y, the current participants of public occupational pensions will also join the Basic Pension as well as the public occupational pensions whose scope of works will be reduced. And finally, The conversion of Retirement Allocation Scheme into a corporate pension should be left to the discretion of the company concerned.

  • An essential part of the development of an autonomous ship is supporting technology that can effectively check and diagnose the operational status of the ship form the shore control center on land. This development has recently occurred in the shipbuilding and shipping industries. In this paper, we present a smart ship solution that operates, as a single system, a data collection platform that gathers ship operation data and a service platform that provides various services. When this smart ship solution was applied to an operating ship, it was determined that a variety of high-quality data could be collected compared to existing ship data collection systems. In addition, it was shown that of the operation data collected, analysis of parameters related to the main engine can be used to determine the overall state by deriving valid results and visualizing patterns. In conclusion, it was suggested that a ship's operation status could be checked more effectively and a comprehensive evaluation could be possible at the shore control center if the results of this study were extended to various ship equipment and analyzed together with the operational environment data.

  • Vehicle communication can facilitate efficient coordination among vehicles on the road and enable future vehicular applications such as vehicle safety enhancement, infotainment, or even autonomous driving. In the $3^{rd}$ Generation Partnership Project (3GPP), many studies focus on long term evolution (LTE)-based vehicle communication. Because vehicle speed is high enough to cause severe channel distortion in vehicle-to-vehicle (V2V) environments. We can utilize channel estimation methods to approach a reliable vehicle communication systems. Conventional channel estimation schemes can be categorized as least-squares (LS), decision-directed channel estimation (DDCE), spectral temporal averaging (STA), and smoothing methods. In this study, we propose a smart channel estimation scheme in LTE-based V2V environments. The channel estimation scheme, based on an LTE uplink system, uses a demodulation reference signal (DMRS) as the pilot symbol. Unlike conventional channel estimation schemes, we propose an adaptive smoothing channel estimation scheme (ASCE) using quadratic smoothing (QS) of the pilot symbols, which estimates a channel with greater accuracy and adaptively estimates channels in data symbols. In simulation results, the proposed ASCE scheme shows improved overall performance in terms of the normalized mean square error (NMSE) and bit error rate (BER) relative to conventional schemes.

  • The sudden emergence of China as a superpower in world politics and economics is apparently a big surprise. This, however, is not an unusual incident. As far as the Chinese are concerned, they say that China is simply running almost the same track that its neighboring countries. In the recent years, a number of experts and scholars have expected that the emergence of China as a great economic power will be argued as a major issue in world politics and economics. So its economic progress will require experts and scholars to watch carefully how China is going to change. It certainly has created an atmosphere that most of the world leaders, experts and scholars are very concerned about China's remarkable performance in its economics and then willing to accept China's rapid growth as an urgent matter. Many experts and scholars began to analyze carefully the factors that have contributed to the rapid growth. Foreign direct investment (FDI), import-export, and economic reform were then listed as the most important factors. As a result, philosophy of economics, analytical economics, and economics are immediately needed for China who is at the moment very anxious to sustain the stable and continuity of rapid economic growth. But unfortunately China does not even recognize the reason why they need to adopt these economic concepts and methods.

  • The discovery of the mirror neuron system (MNS) is one of the most important neuroscientific achievements in the 20th century. Some researchers had reported that MNS dysfunction was discovered in autism spectrum disorders (ASD). Finally, the 'broken mirror' theory of ASD was announced in the mid 2000's. According to this theory, ASD cannot simulate the mind and behavior of others due to MNS dysfunction; therefore, they cannot imitate the behaviors and empathized with the mind of others. However, ASD does not always show imitation problems. The researchers who have criticized the 'broken mirror' theory proposed the 'social top-down response modulation (STORM)' theory. On STORM theory, the medial prefrontal cortex or temporo-parietal junction, brain areas related with mentalising, might modulate MNS according to social context. We compared the strengths and weaknesses of each theory.

  • Basic emotions such as happiness, sadness, anger, fear, and disgust have been widely used to investigate emotion-specific autonomic nervous system activity in many studies. On the contrary, surprise emotion, Suggested also as one of the basic emotions suggested by Ekman et al. (1983), has been least investigated. The purpose of this study was to provide a description of cardiovascular responses on surprise stimulus using electrocardiograph (ECG) and photoplethysmograph (PPG). ECG and PPG were recorded from 76 undergraduate students, as they were exposed to a visuo-acoustic surprise stimulus. Heart rate (HR), standard deviation of R-R interval (SD-RR), root mean square of successive R-R interval difference (RMSSD-RR), respiratory sinus arrhythmia (RSA), finger blood volume pulse amplitude (FBVPA), and finger pulse transit time (FPTT) were calculated before and after the stimulus presentation. Results show significant increase in HR, SD-RR, and RMSSD-RR, decreased FBVPA, and shortened FPTT. Evidence suggests that surprise emotion can be characterized by vasoconstriction and accelerated heart rate, sympathetic activation, and increased heart rate variability, parasympathetic activation. These results can be useful in developing an emotion theory, or profiling surprise-specific physiological responses, as well as establishing the basis for emotion recognition system in human-computer interaction.

  • The purpose of this study is to examine the effects of childcare teacher's professional recognition, learning agility, and positive psychological capital on job satisfaction in order to suggest policies that required for child care teacher's positive performance. For this purpose, an online survey was conducted with 283 in-service nursery teachers in Jeonnam and the results are as follows. First, teachers with more than five years of experience showed higher levels of professional recognition and positive psychological capital. Second, the job satisfaction of child care teachers was highly correlated in order of professional recognition, positive psychological capital, and learning agility. Third, the professional recognition and positive psychological capital of the childcare teachers have positive effects on their job satisfaction. Through this study, it was confirmed that the professional recognition, learning agility, and positive psychological capital of the childcare teachers were significant variables in explaining job satisfaction. Therefore, in order to increase job satisfaction in daycare centers, it is necessary to firmly recognize that they are professional workers by providing training courses and consulting supports. Furthermore, there is a need to allow teachers more autonomy and to reform the hierarchical system in day care places.
