This paper suggests a balanced scorecard (BSC) framework for measuring and evaluating the performance of knowledge workers in professional service firms(PSFs) which are typical knowldege-based organizations. As a strategic learning system, the balanced scorecard allows business leaders to drive and modify their business strategies based on the balanced measurement of key performance indicators(KPIs), which are basically divided into four domains such as financial achievement, customer orientation, internal business process, and innovation and learning. Conducting a focused case study on performance evaluation of knowledge workers from a balanced viewpoint, we could evaluate their competency and potential in more comprehensive manner. We also employ the analytic hierarchy process (AHP) approach for derive relative weights of key performance indicators and link it to a spreadsheet model for rating the individual performance of knowledge workers in a systematic way.

The objectives of this study were to identify current problems and to propose alternatives of woodworking education in school. This study was carried out through the literature review. Even though woodworking in school has a lot of merits, it has not been fully established yet. Current problems in school woodworking were identified as the absence of educational philosophy of woodworking, unambiguous education objectives, incongruity of educational contents and hierarchy, inadequate quality of teachers, poor surroundings for practice, lack of ancillary materials for teaching and learning, and the absence of community for interchanging information. It was proposed that educational philosophy of woodworking and concrete education objectives should be set up, educational contents should be organized in a proper level, and surroundings for practice should be improved. And, it was also proposed that teacher education should be made to upgrade qualities of teachers, ancillary materials for teaching and learning should be developed, and community for interchanging information should be set up.

본 연구는 '식물의 구조와 기능' 단원의 학습 전 아동의 지식구조와 학습과정 및 학습 종료 7개월 후까지의 지식구조의 변화를 아동의 학습성향(유의미학습과 암기학습)과 관련지워 조사한 것이다. 연구단원과 관련된 기존의 지식구조를 알아보기 위하여 5학년 아동들에게 1차 개념도를 그리게 하고, 매 4차시 수업후 각각의 개념도를 그리게 했다. 그리고 지식구조의 지속효과를 알아보기 위하여 단원 학습이 종료된 직후와 3개월, 7개월 후에도 각각의 개념도를 그리게 했다. 학습과정 동안에는 기존의 개념도를 근거로 하여 개념도를 그리게 하였으며, 단원 학습 종료 후에는 기존의 개념도가 제시되지 않은 상태에서 개념도를 그리게 하였다. 아동들이 그린 각각의 개념도는 그 당시의 식물의 구조와 기능에 대한 이해 정도를 나타내었다. 초등학교 5학년 아동들은 '식물의 구조와 기능' 단원의 학습에 들어가기 전에 이와 관련된 여러 가지 개념들로 이루어진 사전 지식구조를 가지고 있으나 그 중 과학적으로 타당한 것은 개념도 상에서 2단계의 위계와 5개의 관계에 불과하였다. 한 단원의 학습이 진행되어감에 따라 아동들의 지식구조는 꾸준히 그리고 점진적으로 증가였다. 그러나 이러한 증가는 학습성향에 따라 차이를 보이며, 유의미 학습자가 암기 학습자보다 더 많이 증가하였다(관계, 연관, 예: p < .01, 위계: p < .05). 지식구조의 변화에 있어서 학습성향간에 다소 차이가 있으나 재구조화는 단원 학습의 초기에 높은 빈도로 일어났으며, 말기에는 전혀 일어나지 않았다. 조정은 유의미 학습자보다 암기 학습자에서 더 많이 일어나고 확장은 이와 반대로 유의미 학습자에서 더 많이 일어났다. 암기 학습자의 개념도 점수는 단원 학습을 마친 후 시간이 경과함에 따라 모든 범주에서 차츰 감소하였다. 그러나 유의미 학습자의 경우 단원 학습 후 3개월보다 7개월에서 오히려 소폭 증가했다. 그러므로 대체로 암기 학습자가 학습과정에서 새로이 구축하고자 하는 더 분화되고 정교한 지식구조가 유의미 학습자보다 불안정한 상태에 있으며, 지식구조의 분화 정도도 유의미 학습자에 비해 낮다고 할 수 있다.

The purpose of this study is to analyze and evaluate the significance of undulated planes of architectural landscape methodology, to assess if the methodology had potential to be a sustainable architectural model, to be experimented in future. To achieve this purpose, the historical origins and changes of the landscape is discussed to analyse how it influenced modern architecture. Then the effects of panoramic sensibility derived from the picturesque garden is analysed to evaluate the influence it had on the change of the perception of space and modern architecture and landscape design strategy. Then 1980s and 1990s' symposiums and landscape theories are examined. To find pivotal moment of merging landscape and architecture, the design schemes of Bernard Tchumi and OMA for La Villette competition are selected as manifestations to show co-existence of landscape and architecture. Afterwards Yokohama ferry terminal is analyzed to present the undulated planes deployed for the union of landscape and architecture, to the affect of uninterrupted spatial connectivity. The impact of undulated plane on interior is explored in analysis of Rolex Learning Center, consequently changing the relationship within functions of the interior and the role of circulation. Finally, the spatial characteristics and significance of undulated plane is explored. The spatial characteristics are, the relationship beyond the visual connection through seamless connection; the multiple access paths and discard of transition space thereby diminishing boundaries; the environmentalization of architecture by spatializing circulation and promoting in-hierarchy. The significance of undulated planes are, the synthesis form of architectural typology; the cultivation of public sense; the closest spatial type to the space of appearance referred to by Hannah Arendt.

The purpose of this study is to empirically analyze the learning experiences of high school mathematics and science subjects of new students in science and engineering, and to provide basic data and respond to strengthen basic knowledge of science and engineering students in the future. The subjects of the survey were 481 freshmen in science and engineering at S University. First, as a result of analyzing the learning experiences of freshmen, the geometric subjects were significantly lower, which is the result of students' sensitive responses to transitional changes in the curriculum and SAT system after revision. In science, general elective subjects were higher than career elective subjects, and there was a deviation between science subjects, which is a result of reflecting the diversity and hierarchy of science subjects. Next, as a result of analyzing the difference in learning experience after revision compared to before the revision of the curriculum, the learning experience of Mathematics II increased significantly and the geometry decreased significantly. Both Chemistry I and II increased significantly compared to before the revision, and Earth Science I decreased significantly. This can be seen as a result of strategic choices based on obtaining grades in the CSAT and disadvantages in college entrance exams. As a result of the study, students' sensitive reactions to changes in the high school education environment were confirmed, basic mathematics and science-related courses were opened to alleviate variations in the academic ability due to elective courses, and countermeasures tailored to each university's situation.

The purpose of this study was (1) to investigate whether linguistic contrast helps children map a new word into a specific semantic domain when a new word is introduced, (2) to examine the existence of a hierarchy of domains into which children will place a new word, (3) to examine whether children's existing lexicons affect how children map a new word. A total of 320 children from 3 to 6 years of age were drawn from Pusan, Korea. The children were divided into one of four age groups. There were 80 children in each age group. In each group, children were randomly assigned to one of four groups; the linguistic contrast group exposed to color, the linguistic contrast group exposed to shape, a label group and control group. All of the children were tested for production and comprehension of the new word. The results of this study were as follows; (1) The linguistic contrast helped children learn the meanings of a new word. Especially, children age 4 or more showed a significant effect for linguistic contrast; however, it was not sufficient to teach 3-year-old the correct, referent of a term. (2) There was a hierarchy of domains into which children mapped a new word. There was no significant effect for domains into which 3-year-old children mapped the new word, but from 4 years of age children showed a preference for assuming a new word refered to an object's shape rather than its color. (3) Children's existing lexicon had no effect, on how children comprehend a new word.

As environmental protection is becoming more and more important, green production has become a key issue for almost every manufacturer and will determine a manufacturer can be sustainable in the long term. Therefore a performance evaluation system for green suppliers is necessary to determine the suitability of suppliers to cooperate with the company. While the works on the evaluation and/or selection of suppliers are abundant, those that concern environmental issues are rather limited. The objective of this study is to construct a combined model based on fuzzy analytic hierarchy process (FAHP) and balanced scorecard (ESC) for evaluating green suppliers in the manufacturing industry. The ESC concept is applied to define the hierarchy with four major perspectives (i.e. financial, customer, internal business process, and learning and growth), and performance indicators are selected for each perspective. FAHP is then proposed in order to tolerate vagueness and ambiguity of information. Finally, FAHP is finally constructed to facilitate the solving process. With the proposed model, manufacturers can have a better understanding of the capabilities that a green supplier must possess and can evaluate and select the most suitable green supplier for cooperation.

The construction industry is the highest safety accident causing industry as 28.55% portion of all industries' accidents in Korea. In particular, falling is the highest accidents type composed of 60.16% among the construction field accidents. Therefore, we analyzed the factors of major disaster affecting the fall accident and then derived feature importances by considering various variables. We used data collected from Korea Occupational Safety & Health Agency (KOSHA) for learning and predicting in the proposed model. We have an effort to predict the degree of occupational fall accidents by using the machine learning model, i.e., Adaboost, short for Adaptive Boosting. Adaboost is a machine learning meta-algorithm which can be used in conjunction with many other types of learning algorithms to improve performance. Decision trees were combined with AdaBoost in this model to predict and classify the degree of occupational fall accidents. HyOperpt was also used to optimize hyperparameters and to combine k-fold cross validation by hierarchy. We extracted and analyzed feature importances and affecting fall disaster by permutation technique. In this study, we verified the degree of fall accidents with predictive accuracy. The machine learning model was also confirmed to be applicable to the safety accident analysis in construction site. In the future, if the safety accident data is accumulated automatically in the network system using IoT(Internet of things) technology in real time in the construction site, it will be possible to analyze the factors and types of accidents according to the site conditions from the real time data.
