Ultrasonic sensor is suitable as a next-generation autonomous driving assist device because its lower price compared to that of other sensors and its sensing stability in the external environment. Although Pb(Zr, Ti)O₃ (PZT)-relaxor ferroelectric system has excellent piezoelectric properties, the change in capacitance is large in the daily operating temperature range due to the low phase transition temperature. Recently, many studies have been conducted to improve the temperature stability of ferroelectric ceramics by controlling the grain size and crystal structure, so it is necessary to study the effect of the grain size on the piezoelectric properties and the temperature stability of PZT-relaxor ferroelectric system. In this study, the piezoelectric properties, phase transition temperature, and temperature coefficient of capacitance (TCC) of 0.9 Pb(Zr_1-xTi_x)O₃-0.1 Pb(Zn_1/3Nb_2/3)O₃ (PZT_x-PZN) ceramics with various grain sizes were investigated. PZT_x-PZN ceramics with larger grain size showed higher piezoelectric properties and temperature stability, and are expected to be suitable for ultrasonic devices in the future.

Until now, Academic disciplines were categorized according to the standards of the National Research Foundation of Korea, and this categorization has contributed to the development of each disciplines. However, as time goes by, there is a need for a transition to the new trends, convergence. Therefore, to suggest the resolution for pre-existing phenomenon and problems, this study explored the concept and traits of narrative science as a convergence discipline and discussed its implications and tasks. Narrative Science is a human science, based on narrative epistemology, and it focuses on human's interpretation, communication, and inter-subjectivity. Narrative Science has many inner structures per trait, and it provides pre-existing disciplines with narrativistic inter-relation. It also pays attention to human's inner areas. For the development of Narrative Science in the future, it should be free from a misunderstanding as a narratology discipline or a methodology of qualitative research. Under this change, Narrative Science discipline areas should be fused in the perspective of human science, based on narrative philosophy and psychology.

Implantable bioabsorbable combination products undergo inherent degradation and systemic absorption within the physiological environment, thereby streamlining the therapeutic regimen and obviating the imperative for invasive extraction procedures. This inherent property not only enhances patient convenience and therapeutic efficacy but also underpins a paradigm of support characterized by heightened safety parameters. Within the regulatory landscapes of Korea, the United States, and Europe, implantable bioabsorbable combination products are meticulously classified into distinct categories, either as pharmaceutical implants or as implantable medical devices, depending on their primary mode of action. This scholarly investigation systematically examines the regulatory frameworks governing implantable bioabsorbable combination products in South Korea, the United States, and Europe. Notable discrepancies across national jurisdictions emerge concerning regulatory specifics, including terminology, product classification, and product name associated with these products. The conspicuous absence of standardized approval regulations presents a formidable barrier to the commercialization of these advanced medical devices. This academic discourse passionately emphasizes the critical need for formulating and implementing a sophisticated regulatory framework capable of streamlining the product approval process, thereby paving the way for a seamless path to commercializing implantable bioabsorbable combination products.

'Transference phenomenon' is considered as a essential feature in psychotherapy as well as psychoanalysis. But there is much difference in conceptual and methodological issues for 'transference phenomenon' among various psychoanalytical schools. In general, the depth psychological studies for 'transference phenomenon' are mainly from the psychoanalytical view of point but relatively sparse from the analytical psychological view of point which has more holistic and deeper understanding for human psyche. So this article was intended for a comprehensive review of 'transference phenomenon' from the perspective of analytical psychology and tried to make an understanding for its meaning. To begin with, the concept of 'transference phenomenon' was investigated from the view before Jung and after Jung, with Jung's view in the center. Then it was made clear that 'transference phenomenon' from the perspective of analytical psychology could be understood by several characteristic aspects. It was suggested that a careful study on the symbolic meaning of the woodcuts' pictures in Rosarium Philosophorum including a proper interpretation of its posterior part to which Jung didn't refer in "The Psychology of The Transference" be devoted to the genuine understanding of 'transference phenomenon' from the perspective of analytical psychology afterwards.

The psychology of Carl G. Jung is often called an "ancilla religionis"(servant of religion, James Heisig), by which Jung's understanding of the unconsciousness of human being as the religious one is well expressed. According to Jung the dichotomy between the consciousness and the unconsciousness of men is reconciled in the various religious symbols of the world religions. He also asserted that the religious symbols must be understood and interpreted by a symbolical way. When the religious symbols are understood literally and dogmatically, they lost their dynamic power to bring salvation to men. In this paper I try to understand the essence of the symbolical and intuitional understanding of the exclusiveness of Jesus Christ. The confession of the Christianity that only Christ, once for all, could bring the salvation to the whole humankind is to be interpreted by a symbolical and intuitional way. That means, Christ is to be understood as a always new being at every time when he is confessed as a salvator. Christ as a symbol could never be a historical past. I mentioned about the understanding of Buddha by Muneyoshi Yanagi, a Japanese Shinto Buddhist, in order to show how such a symbolical and intuitional understanding of the Christ could be possible.

The economic growth that depended on IT industry is reaching to a limit. In order to overcome the limit, the convergence industry that makes new market and products is essential. However, companies preparing a jump into the convergence industry must understand the exact visions and characteristics of convergence. Therefore, we investigated the structural changes of industries caused by convergence and importance characteristics of convergence. Also, we demonstrated the current status of the convergence industry and analyzed economical, social/cultural, and technological environments that the companies are facing, and elaborated the opportunities of convergence. At last, we suggested basic requirements and strategies for companies starting a convergence business and IT utilization methods to accelerate the convergence business activation.
