  • Recent advances in cell biological and genetic researches have revealed that mitochondrial morphology is highly dynamic and regulated by multiple molecular factors including dynamin-related proteins (DRPs). Considering that the mitochondria play critical roles in the cellular metabolism via ATP synthesis, calcium homeostasis in cooperation with endoplasmic reticulum, and apoptosis, the failure of mitochondrial dynamics is infrequently related to the failure in the normal growth and cellular integrity. In this respect, alteration of mitochondrial dynamics may greatly affect the development of nervous system. In this short review, we discussed molecules involved in the control of mitochondrial dynamics, and provide some perspectives on their significance in the neuronal development.

  • Dynamics of Sijo was regarded as a genre of 'closed nature' once. But ironically thanks to the 'closed nature', today dynamics of Sijo is refocused in diverse fields. Sijo is quoted not only in its original field of literature, but also in writing study. Quite remarkably, it is often referred to in the field of literary therapy, further in emotional healing. This article discussed the dynamics of Sijo as a manifestation of emotion especially called Gamsung in the process of the refocus. It is to show effectively that as a literary genre, Sijo can interact and share what is reasonal as well as what is emotional and sentimental in a poem as an emotional container beyond the lyricism Sijo has. Of course, it is also clear that the concept of lyricism may limit the dynamics of Sijo itself. Thus, the key word 'Gamsung' mainly referred to in this article was used to show the dynamics which Sijo has as much as possible, overcoming the limitation. That is, the purpose of the study is to prove that Sijo is the genre to represent human emotion most dynamically by reviewing the reasonal aspect of Sijo in addition to its emotional disposition which has been estimated to focus on sentiment or emotion. In the process of reinterpreting the structure of Sijo, the specific analysis on such emotional disposition and reasonal aspect was conducted by structurizing that as '(1) Facing, (2) Feeling dynamical, (3) Interpellating by feeling, and (4) feeling by sensation'.

  • This paper investigates the effects of technology collaboration between the main supplier and buyer on buyer's new product development under dynamic environment. Based on 428 Korean manufacturing firms, we conducted regression analysis. The technology collaboration between the main supplier and buyer is adopted as a independent variable and quality, cost and lead time performance of new product development projects are used as dependents variables. Environment dynamic is also used as a moderate variables. We found that the in general, technology collaboration is positively associated with the performance of buyers' new product development, but in the high degree of dynamic environment, technology collaboration is negatively associated with the performance of buyers' new product development unlike our expectation. Thus, we divide our sample into two groups; shipbuilding industry with the low degree of environment dynamic and electronic and IT device industry with the high degree of environment dynamic and conducted a post hoc analysis. As a result, in ship building industry, the technology collaboration is significant to improve NPD projects performance, while in electronic and IT device industry, the technology collaboration with a main supplier is not significant as well as coefficient is negative. In that, under the highly dynamic condition with the fast change of technology and products obsolescence the NPD collaboration with the main supplier does not works unlike a stable environment. This implies that the NPD attributes of buyer are different by their environmental factor and the fit between given environmental feature and the collaboration synergy is critical factor for improving the effect of NPD collaboration between supplier and buyer.

A Study on the influence of the Transformational Dynamics of Venture to Organizational Commitment and Job Satisfaction at the Convergence age - Moderating Effect of the Position Type (융·복합 시대, 벤쳐 기업의 변혁적 역동성이 조직몰입과 직무만족에 미치는 영향에 관한 연구 - 직급별 조절효과 관점에서)

  • This study was performed to study the factors appear to SMEs and how differently depending on the worker ranks at the convergence age. Additionally, numerous studies and results on the factors which affect the organization's performance was to individually different approach to integrated. Especially venture was divided by a factor of enterprises and transformational dynamics factors and commutative Dynamics factors and approaches in terms of the impact transformative dynamics of which factors are organizational commitment and job satisfaction. A transformational dynamism to the four factors were such as mission and strategy, CEO Leadership, Manager, leadership, organizational culture variables. The study was based on theoretical models of organizational development, Burke and Litwin (1992). They were classified as managers and production workers. By obtaining data from employees 630 people engaged in a total of nine manufacturers were analyzed. The average variable based on the organization's Burke and Litwin (1992) theory of transformational variables is one that Nana was aware of the organizational commitment, and job satisfaction. Correlation analysis transformational dynamics variables're having an impact on job satisfaction and organizational commitment, job position is found to have moderating effects.

  • This study was to analyze the visual preference of the port landscapes for North port in Busan. Preference related variables came from Semantic Differential(SD) method and then were conducted by the factor analysis. Multiple regression was done for the relationship between the preference and factors. The result found 4 factors, including dynamics, stability, pleasantness and healthiness. Much importance was placed on dynamics among them. Therefore, building port landscapes and their image attracting viewers should consider dynamics in terms of port landscape plan and user attraction development for visual quality management.

  • The purpose of this study is to identify the types for open innovation of SMEs considering strategic- culture mixed typology and environmental dynamism. The analysis results of 182 SMEs classified into 4 groups are as follows. First, type PD had a positive effect on innovation performance in both in-bound and out-bound innovation and had improved performance through in-bound innovation in a dynamic technical environment. While DH had no significant effect on both innovations. Second, PH and DD, strategy-culture mismatched types, had a single effect of innovation that affected performance. No moderating effects of environmental dynamism had been shown in types PH, DD, DH. SMEs that aim for open innovation should strive to improve performance by aligning change-oriented strategy with creative and challenging culture.

  • This paper attempts to examine complicated relations which the nineteenth-century English novel of female development has with the Bildungsroman genre, and to discuss that the story of female development effectively realizes the potential dynamics of the genre. It looks into the history of discussions on the Bildungsroman which began at the end of the nineteenth-century in Germany and developed among twentieth-century Anglo-American critics, and those on the female development which didn't start until feminist criticism ventured out at the end of 1970s, and have developed into various perspectives ever since in accordance to the progress of feminist criticism. In general, Bildungsroman criticism considers that it portrays the process how the protagonist develops self and achieves an accommodation with society. However, this paper points out that the Bildungsroman is the narrative form which represents conflicts between self and society caused by idealizing the infinitive possibility of self-determination while simultaneously presenting the limited goal of social integration. It argues that the subversive dynamics of the genre can give full play to its potential when it reveals contradictions and tensions between individual subjectivity and integration into society and connects them with criticism of political and social structures. It is the stories of female Bildungshelds depicted by nineteenth-century female writers that exquisitely embody the subversive potential of the Bildungsroman. They acutely experience alienation from society where independency or autonomy is fundamentally impossible because the ideology of separate spheres does not allow them to live a meaningful life economically and sociologically outside the marriage. An example of a female Bildungsheld whose conflicts between development of self and integration with society are doubled by gender is Jane Eyre. Jane Eyre is a representative Bildungsroman with subversive dynamics, which tells the story of female development but splits itself through various techniques inserting contradictory and opposite meanings, thus resignifying female development and questioning social and political structures.
