  • Following a microgenetic design, this study was analysed the characteristic and the change of classification strategy that appear in college students' classification activity. The 4 tasks were developed for classification activity; a shell as a familiar real things, an animal fossil as a unfamiliar real things, a snow flake as a familiar picture cards and galaxy as a unfamiliar picture card. Achieved study to 6 college students who major in elementary education. Data were collected by interview with subjects, subject's classification schema, investigator's observation of subject's activity, and videotaped that record subject's subject classification process over an extended period of 6 times. Result proved in this study is as following. In the 6 times of the data collection procedures, a strategy F identifying concrete attribution of classification objects and a more detailed strategy X3 combining qualitative, spatial and dimensional attribution were found and more frequently used in both groups of college students which reported a classification process and did not report the process. While discovery and absorption of both a concrete classification strategy and a detailed classification strategy were rapidly developed in the reporting group, they were gradually developed in the non-reporting group. In addition to this, as the data collection procedures were progressing, the college students were familiar with change factors of classification tasks and in the case of pictures the classification strategy showed more desirable changes.

  • The tasks of writing history is to reconstruct the past in order to understand the present condition and to envision the future. Modern architectural histories in the west have assumed this role, from Winckelmann to Giedion. Likewise, history of Korean modern architecture has to serve this purpose. However, existing histories of Korean modern architecture simply list up stylistic changes from western eclectic architecture to modernism without any historical narratives explaining the transition from Korean traditional architecture to modern architecture. History of Korean modern architecture has simply been understood as a unilateral process of transplantation of western architecture into Korea. This paper points out two major problems underlying this kind of historiography of Korean modern architecture. The one is formalistic approach which sees history of modern architecture mainly as a process of formal and stylistic changes. The other is humanistic approach which sees modern architects as agents of history. This paper argues that this kind of history writings has limitations since modernity of Korean architecture is fundamentally different from that of the west. and that specific tasks that Korean modern architectural history has to address are then two folds;(re)connecting the past architectural tradition to the present and forming self-identity of Korean architecture.

  • IT outsourcing providers has been expanded from a single functional system to the entire IT service to gain sustainable competitiveness. This new trend of IT outsourcing need outsourcing management capability based on a firm's core capacity. Hiring external IT service providers to manage part or all of its information-related services helps a firm focus on its core business and provides better services to its clients, thus obtaining sustainable competitive advantage. This research investigates the major factors that determine the level of a particular firm's success at IT outsourcing. Based on process innovation and core-competency theories, we identify three significant components of a firm's IT outsourcing management method (ITOMM): level of core-competency-based management, maturity of outsourced tasks, and maturity of outsourcing management. Comprehensive data collection was conducted through an outsourcing association. The survey data were analyzed using a structural analysis method. Maturity of outsourced tasks and maturity of outsourcing management were found to affect project performance directly, while level of core-competency-based management only indirectly impacted project performance through its positive impact on the other two ITOMM components.

  • Unless the records appraisal system is properly overhauled, there is no future for public records management. This study aims to highlight challenging issues and present improvement tasks necessary for the readjustment of the public records appraisal system at the national level. First, public records appraisal policies are divided into five categories: i) statements on appraisal policy and selection criteria, ii) appraisal tools such as disposition authorities, iii) subject of appraising, iv) appraisal procedures, and v) responsibility and authority in appraisal and disposition process. Second, the domestic situation is identified for each category. Third, policies of the United States, United Kingdom, Australia, and Canada are compared, and implications are derived for each category. Fourth and last, the tasks for the readjustment of the public appraisal system are proposed based on these analyses.

  • In recent years, work-related musculoskeletal disorders (WMSDs) are one of major issues in occupational safety and health in Korea, since the number of injured workers has rapidly increased and the related regulation was amended to improve the work conditions. Main risk factors of WMSDs in Korean industries include manual handling of heavy weight loads, awkward postures, repetitive tasks, prolonged static muscle contraction, and so on. in this article, some ergonomics case studies for identifying the risk factors of WMSDs and far their prevention were introduced. They include a biomechanical analysis for the heavy-weight handling task in a machine-repair shop, physiological evaluation of backpack-carrying tasks in a beverage delivery job, and a set of psychophysical studies to evaluate static-postural load. These studies showed that there are several different ergonomic approaches to identifying and evaluating risk factors of WMSDs and to eliminating them or reducing their levels, and that it is important to select proper methods and apply them in improving the work conditions according to the characteristics of the task. In addition, it needs to develop practical and effective ergonomic tools to prevent WMSDs and to provide these tools to the safety managers in the field so that they can improve the tasks by themselves.

  • This article links the change in regional manufacturing employment in Korea after the financial crisis to the geography of technological and trade shocks. We conceptualize the trade shock as the rapid growth in Korean imports from and exports to China and ASEAN countries. We then measure the exposure to technological shocks as the degree to which regions are specialized in routine tasks, which are susceptible to automation technologies. Results show that local labor markets specialized in routine tasks experience significant falls in manufacturing employment. Regions whose industrial structure exposes them to rising import competition experience sharp drop in manufacturing employment. We also found that export plays a major role in explaining the growth of regional manufacturing employment.

  • A construction project is a complex process consisting of interdependent tasks. If one task has variation, other tasks will be affected additionally and it is difficult to reach consensus on task variation due to the characteristics of the construction site that is going on quickly and complicatedly. Therefore, this study identified the root cause of task variation in construction process. Adjacent matrix was created with the tasks corresponding to major causes of variation, and the network analysis was performed. The results of social network analysis in the construction process can stabilize the work flow in the complex process and improve the reliability of the process plan and the project performance.

  • Although the globally known one-child policy in China was abolished in 2016, the overall fertility rate in the country declined to 1.3 in 2020. In this study, we examined whether the achievement of major developmental tasks during the childrearing stage was associated with intentions to have a second child among Chinese married women. Based on family development theory, we included parenting adaptation, division of childcare responsibilities with the partner, and marital adjustment as key developmental tasks during the childrearing stage. The participants of this study were 315 married Chinese women who lived with a spouse and a child who had not yet entered elementary school. Data were collected through an online survey in February and March 2021. A multiple regression analysis of the data revealed that a lower level of economic parenting stress, a higher level of fairness in dividing childcare responsibilities with the partner, and a more positive change in their marital relationship after having the first child were associated with greater intentions to have a second child.
