조직의 지속가능한 경쟁력 확보를 위한 지식경영(Knowledge Management)의 중요성에 대한 인식은 건설산업 내에서도 높아져 가고 있다. 하지만, 이러한 지식경영을 실행하기 위해 도입된 IT 도구들의 활용도나 효과성은 만족스럽지 않은 수준에 그치고 있고, 이는 전체 지식경영 성과에 대한 불만족으로 이어지고 있다. 이에 본 연구에서는 현재 한국 건설산업에서의 지식경영 사례에 대한 조사를 토대로 현재의 하향식 지식관리 방법론과 이를 반영하는 지식관리시스템이 갖는 문제점을 분석하고, 이러한 문제점을 개선할 수 있는 상향식 지식관리 방법론을 제시하고, 이를 시스템으로 구현하고자 한다. 또한 본 연구에서는 제안된 시스템과 기존 사례의 지식관리시스템과의 사용성 비교를 통해 그 사용성과 효과성에 대한 검증을 하고자 한다.

본 연구는 문헌연구를 통해 이론과 실천의 관계에서 교수 행위를 바라보는 상반된 두 가지 관점 중 bottom-up 관점에서 유아 교사의 실천을 탐색한다. 연구 결과는 다음과 같다. 첫째, 전통적으로 유아교육에서는 top-down 관점을 중심으로 발달심리학 이론, 발달에 적합한 이론과 실제에 관한 담론, 그리고 발달이론에 근거하여 개발된 다양한 프로그램모델의 틀 안에서 유아교사의 실천과 교수행위를 정의하고 합리화해 왔다. 둘째, 이와 반대로 bottom-up 관점은 현장에서의 교사의 행위와 실천이 이론을 이끈다고 보며 반성적 사고를 통해 교사가 현장에서 실천방법을 구성해 가는데 초점을 둔다. 이 관점에서 실천은 이론의 근거가 되며, 교사는 암묵적 이론을 형성하면서 연구자의 역할을 한다고 보면서 개인경험, 학교풍토와 맥락, 그리고 우세한 교육담론이 교사의 이론을 구성하는 데 영향을 미치는 요소로 본다. 셋째, 실제로 예비교사와 현직교사를 대상으로 하는 연구결과로부터 예비교사는 경험으로부터 오는 교수에 대한 기대가 양성과정에서의 담론과의 교류, 실습 및 학교의 영향으로부터 교수에 대한 이론을 발달시킨다는 것을 보여준다. 또한 현직교사들은 그들이 지닌 암묵적 지식의 전개가 지속적인 전문성 발달과 관련이 있으며 행정적 압력 및 현장의 복잡한 현실적인 문제들을 개인적으로 발달시킨 전략을 사용하여 해결함을 보여준다. 연구 결과에 따라 bottom-up 관점에 근거한 향후 교사 실천에 관한연구 방향과 시사점을 제안하였다.

In order to maximize the effect of TQM in the Korean industry, quality circle activity as a bottom­up management should be expanded and revitalized. Quality circle activity can be regarded as a kind of knowledge activity where new knowledge is created and knowledge is shared in the economy. This paper proposes new metrics of intangible effect as knowledge assessment focusing on the intellectual capital aspect of quality circle activity, that may be useful for revitalizing quality circle activity from viewpoints not only of financial effect but also of intellectual capital aspect. New metrics of intangible effect consist of two factors： the intellectual capital effect and the intellectual maturity effect. In order to test the validity of new metrics, a case study of 11 companies was done. The result of the case study is that two factors as an intangible effect of quality circle activity should be evaluated to identify the total effect of quality circle activity correctly.

Recently, Korea aimed to increase water use efficiency by implementing integrated management according to the water management unification policy. Considering the enormous use of water resources in the agricultural sector, it is necessary to efficiently conserve water in terms of demand management by intensifying the stakeholders' involvement and awareness campaigns. The existing agricultural water management system in Korea is based on a top-down approach by which the government agencies directly plan budgets and policies to be enforced on and implemented by farmers, with little to no involvement of farmers in the decision-making process. However, this process has hindered the desired water resources management and the water conservation goal at the field level. Moreover, the limited research on water governance operations focusing on agricultural water creates a knowledge gap, particularly in Korea. Thus, it is necessary to investigate water governance cases with successful implementations in agricultural and rural areas to identify the factors applicable to domestic governance in Korea. In addition, a more systematic governance model should be established by identifying the subjectivity of the stakeholders' involvement in agricultural water governance. Therefore, this study proposed a new bottom-up model for agricultural water governance, which aims to raise the problem of autonomous water governance while promoting stakeholders' voluntary participation in agricultural water management and reflecting farmers' involvement in the decision-making process. Moreover, if agricultural water governance is expanded nationwide by reflecting agricultural and water resource policies in the future, it is believed that positive effects can be achieved in increasing utilization efficiency and securing sustantiality through agricultural water saving.

The purpose of this research is to suggest the promotive directions of Quality Circle activity. Since 1975, variety of organizations in Korea have widely the implemented Quality Circle activities for their management systems. Today, Companies are facing the harsh realities of a competitive environment. This is no time for revolutionary change. Instead, Companies are instituting revolutionary change meant to have impact within a very short time frame. The Worker's Quality Circle activity is, essentially, a trouble shooting oriented voluntary small group within their working place to improve the surroundings creatively. The industries have enthusiastically used Quality Circle activities and were influenced from them. The Quality Circle activities can be regarded as a kind of Knowledge Management where new knowledge is created and knowledge is shared in the economy. However, the academics were less interested in this subject, as a result, there were no systematic guidances for Quality Circle activities. Also, the government was less interested in these activities, as a result, there were no systematic policy making for Quality Circle activities. Thus, in this research, the promotive directions for Quality Circle activities were suggested which were based on the results of survey Questionnaires presented to promoters of the domestic companies. As a results of this research, to maximize the effect of TQM(Total Quality Management) in the nationwide, Quality Circle activity as a bottom-up management should be more expanded and revitalized.

This research investigates the automatic identification of typical embedded structures in the Integer Programming(IP) models and automatic transformation of the problem to an adequate Lagrangian problem which can provide tight bounds within the acceptable run time. For this purpose, the structural distinctiveness of variables, constants, blocks of terms, and constraint chunks is identified to describe the structure of the IP model. To assist the identification of the structural distinctiveness, the representation by the knowledge based IP model formulator UNIK-IP is adopted. For the reasoning for the structural identification, the bottom-up, top-down, and case-based approaches are proposed. A prototype system UNIK-RELAX is developed to implement the approaches proposed in this research.

Research on group decisions and electronic meeting systems have been increasing rapidly according to the widespread of Internet technology. Although various issues have been raised in empirical research, we will try to solve an issue on idea categorizing in the group decision making process of electronic meeting systems. Idea categorizing used at existing group decision support systems was performed in a top-down procedure and mostly b participants; manual work. This resulted in tacking as long in idea categorizing as it does for idea generating clustering an idea in multiple categories, and identifying almost similar redundant categories. However such methods have critical limitation in the electronic meeting systems, we suggest an intelligent idea categorizing methodology which is a bottom-up approach. This method consists of steps to present idea using keywords, identifying keywords' affinity, computing similarity among ideas, and clustering ideas. This methodology allows participants to interact iteratively for clear manifestation of ambiguous ideas. We also developed a prototype system, IIC (intelligent idea categorizer) and evaluated its performance using the comparision experimetn with other systems. IIC is not a general purposed system, but it produces a good result in a given specific domain.

The Jinshanling section of the Great Wall of China is a series of fortifications in northern China that was constructed for strategic military defenses. This section was first built in the beginning of the Ming Dynasty in AD 1368 and then underwent major construction, reconstruction and renovation during the late Ming Dynasty, approximately in AD 1569. The Jinshanling section is 10.5 km long, a very short section compared with the entire 21,200 km wall. The wall section is located in Luanping County, Hebei province, China. This research paper focuses on the construction methods and materials of the wall and the towers in the area. The research methodology includes site visits, knowledge acquisition of experts and 3D graphic modeling. This study reveals that the materials selected for the structure include rubbles and rammed earth, bricks, stones, timber, and mortar. The erection sequence of the wall and the towers was a bottom-up fashion using various ancient construction techniques, such as the fire-setting rock blasting techniques and the surveying techniques from the Sea Island Mathematical Manual.
