This study empirically verified the effect of environmental dynamism on changes in the dynamic and operational capabilities of an enterprise and its innovation performance. With the aim of quantification, the concept and definition of each capability were defined as a hierarchical structure of dynamic and operational capabilities. Five research hypotheses were established through prior research on dynamic capabilities, operational capabilities, innovation performance, and environmental dynamism. For empirical analysis, the hypotheses were verified based on surveys from 300 Korean manufacturing companies. It was shown that Dynamic capabilities had a positive relationship with operational capabilities and operational capabilities had a positive relationship with innovation performance. And it was shown that operational capabilities had a positive relationship with radical innovation in business groups with high environmental dynamism while operating capabilities had a positive relationship with gradual innovation in business groups with low environmental dynamism. Also, the moderating effect of environmental dynamism was not significant in the relationship with dynamic capabilities on operational capabilities. This study is meaningful in that it lays the groundwork for empirically verifying the dynamic capabilities of an enterprise by embodying its dynamic capabilities and operational capabilities into processes, and verifies the effect of environmental change on its capabilities and innovation performance. And it has implications to suggest how an enterprise should transform its capabilities to sustain its competitive advantage in a rapidly changing environment.

This study was conducted with the purpose of exploring the relationship dynamics of couples who experienced dating violence. For this purpose, interviews were conducted with 15 couples who experienced dating violence. The collected data was analyzed using the consensual qualitative research(CQR) method. As a result, 3 domains, 13 categories, and 30 subcategories were derived. Domain 1 was about "the direction of the dynamics of perpetration and victimization, types of violence, and experience level," and found that the dynamics of perpetration and victimization are bidirectional, and that there are situational and controlling types of violence. For domain 2, we explored "major conflict themes, unique perceptions, and psychological dynamics of violence" and identified "other and communication issues" and "interference and personality issues" as major conflict themes, "gender stereotypes" and "violence permissive beliefs" as unique perceptions, and "attribution styles," "major emotions," and "coping styles" as psychological dynamics of violence. For domain 3, we looked into the 'changes in commitment and satisfaction as well as relationship maintenance factors' and presented changes in commitment and satisfaction, and found that the relationship maintenance factors were divided into positive and negative factors. These results are significant in that dating violence consists of mutual abuse and that it empirically revealed the detailed elements of the psychological dynamics of male and female. This was compared and analyzed with previous studies, and limitations and future research were also presented.

This paper critically examines cluster dynamics and development in a multi-scalar approach, criticizing both the argument overemphasizing local networks and endogenous development for regional development and the contention highlighting global networks and the role of global players. We argue that state policies, exogenous and direct, play a significant part in cluster dynamics and development especially in the case of Korea where the state government's strong policies have led to rapid industrialization. We analyze multi-scalar factors, especially the government policies at a national level, in the development paths of the three cases including Ulsan automobile cluster, Daedeok research cluster, and Dongdaemun fashion cluster.

The purpose of this study is to investigate the antecedents of city brand personality and those effects on city brand personality and attitude toward city. This study attempts to confirm dimensions of city characteristics and city brand personality, and analyze the structural relationships among the city characteristics, city brand personality and attitude toward city. The result showed that various characteristics of city (culture and historic characteristics, life stability, facility convenience, economic factors, the image of city appearance, nature friendly characteristics) influence city brand personalities. In addition, city brand personalities (vivid personality and stable personality) are positively related to attitude toward city and mediated between the characteristics of city and attitude toward city.

The Reality Dynamic Counseling which reflects Korean culture and Korean sensibilities has been introduced as a model of Korean counseling approach. This is a qualitative study to examine how the characteristics of Reality Dynamic Counseling appear upon the real counseling process for the clients who were physically attacked by their own son and were brought to this counseling export from juvenile counseling service center. The major properties of Reality Dynamic Counseling are grasping the problem with connecting whole context, dealing with an external world as well as an internal world, emphasizing a role in relation with others, serving as a fosterer or an educator for counselor, confronting a client to awake from a disillusion, restoring to the good relationship between a parent and a child, and pulling a client to the relation with people. These properties are well brought out in the real counseling process. The Manual written by a counselor which gives us detailed commentary on counseling process was selected and analyzed in this study because the protocol between a counselor and a client was too large quantity and it could not show on how to change like facial expression and voice.

Purpose: In this study, we compared the quantitative characteristics of dynamic salivary gland scintigraphy with static scintigraphy in patients with clinical sicca syndrome using Tc-99m pertechnetate. Materials and Methods: Fifty-two parotid glands and 52 submandibular glands out of 26 patients with clinical sicca syndrome were studied by dynamic and static salivary gland scintigraphy. Ten normal volunteers were also studied as a control group for comparison of scintigraphic parameters. Ten minutes after injection of 370 MBq Tc-99m pertechnetate, we obtained pre-stimulus static images for a few minutes. Then dynamic salivary gland scintigraphy with lemon juice stimulation was performed for 20 minutes. Finally we obtained post-stimulus static images after dynamic images. On dynamic study, functional parameters such as uptake rate, secretion rate and re-uptake rate were calculated. The results of dynamic study and static images were compared. Results: On dynamic study, we could obtain functional parameters of salivary glands successfully. On dynamic study, 22 parotid glands and 22 submandibular glands out of each of 52 glands are abnormal. The static images demonstrated somewhat different results, of which reasons we could assume via dynamic study. Conclusion: Dynamic salivary gland scintigraphy using Tc-99m perechnetate were more functional than static images and might be useful in the assessment of the functional change of the salivary gland in patients with clinical sicca syndrome.

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.

The importance of identifying gifted children during early childhood is becoming recognized. Nonetheless, most researchers preferred to study the primary and secondary levels where children are already and more clearly demonstrating what talents they have, and where more reliable predictions of gifted may be made. Comparatively lisle work has been done in this area. When we identify giftedness during early childhood, we have to consider the potential of the young children rather than on actual achievement. Giftedness during early childhood is still developing and less stable than that of older children and this prevents us from making firm and accurate predictions based on children's actual achievement. Dynamic assessment, based on Vygotsky's concept of the zone of proximal development(ZPD), suggests a new idea in the way the gifted young children are identified. In light of dynamic assessment, for identifying the potential giftedness of young children. we need to involve measuring both unassisted and assisted performance. Dynamic assessment usually consists of a test-intervene-retest format that focuses attention on the improvement in child performance when an adult provides mediated assistance on how to master the testing task. The advantages of the dynamic assessment are as follows: First, the dynamic assessment approach can provide a useful means for assessing young gifted child who have not demonstrated high ability on traditional identification method. Second, the dynamic assessment approach can assess the learning process of young children. Third, the dynamic assessment can lead an individualized education by the early identification of young gifted children. Fourth, the dynamic assessment can be a more accurate predictor of potential by linking diagnosis and instruction. Thus, it can make us provide an educational treatment effectively for young gifted children.
