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.

This study examined the knowledge structure constructed by children before formal instruction, and successive changes in the structural complexity of knowledge during and after the learning of 'Structure and Function of Plant' unit. It also investigated how those changes were affected by children's learning modes. The researchers made the 5th graders draw the first draft of their concept map to see the pre-existing knowledge structure concerned with the unit and four more concept maps after completing every fourth lesson. And to see how long their knowledge structures were preserved, the researchers made children draw additional concept maps in 3 days, 3 months, and 7 months after completing the unit. Children drew their current concept maps on the basis of the previous one while learning the unit and without the previous one after completing the unit. Each concept map drawn by children showed the degree of their current understanding on the structures and functions of plants. The results revealed that only two levels of hierarchy and five relationships among the components of the first concept map(relationship, hierarchy, cross link and example) were proven to be valid in terms of conceptual relevance. Growth in the structural complexity of knowledge took place progressively throughout the unit and the effects of learning mode on the growth were favorably reflected in concept map scores of meaningful learners over time(relationship, cross link, example: p<.01, hierarchy: p<.05). Although there were some differences on the concept map scores between two types of learners, they commonly showed that knowledge restructuring had occurred apparently in the early periods from the 1st to the 6th lesson and had not occurred at all in the last period of the unit. The frequency of tuning was higher in rote learners than in meaningful learners throughout the unit, but the frequency of accretion was reverse. Concept map scores of rote learners constructed in the course of learning of the unit decreased little by little gradually in all the categories after completing the unit. However, the average total map score of meaningful learners increased a little more in 7 months than in 3 months after completing the unit. Therefore it can be inferred that meaningful learners construct more stable and well-differentiated knowledge structures than the rote learners.

The 7th national curriculum is focused on breeding an independent and creative Korean who will lead the age of globalism and information in the 21st century. It is necessary to improve the existing assessment methods in order to develop higher thinking abilities such as creativity and problem-solving skill. Although teachers have been aware of this necessity, they have realized that it is difficult to improve the current assessment methods. In this study, we selected some assessment domains on science learning with literature reviews and case analysis. In addition, we calculated the degree of its importance by the use of Analytic Hierarchy Process(AHP). We suggest a direction for improving the present assessment domains on science learning on the basis of the research. Inquiry, cognitive, creative, and affective domain among assessment domains seemed to be listed in order of importance. Moreover, problem-identifying, hypothesizing, and inquiry-planning appeared to be the highest in the degree of importance among sub categories. Considering the results of this study, the current school assessment system which is focused on cognitive domain should be improved.

Concerning elementary school science subject electric circuit units, which are regarded as difficult by teachers and students, this study aims to use the knowledge state analysis method along with interviews to analyze the knowledge state and hierarchy of inquiry abilities. Before and after applying the electric circuit inquiry abilities module, the question items aimed at assessing the basic inquiry abilities and integrative inquiry abilities for electric circuits were presented to students, and their knowledge state was analyzed along with interviews. Through analysis of the knowledge structure and hierarchy of inquiry abilities about electric circuits, the way of thinking of teachers who taught inquiry abilities, and the way of thinking of students were found to be visually different from each other, and this is an important factor that should not be neglected in the process of teaching and learning about inquiry abilities and should be considered. In addition, the presentation of the knowledge state of and hierarchical relations between inquiry abilities factors can offer implications for guidance on students' learning about inquiry abilities.

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.
