The purpose of this study is to develop the 'Kkondae Scale' and verify its validity. For this purpose, three constructive concepts (attribution error, cognitive rigidity, and one-way communication) were derived through expert interviews, prior research and literature analysis, and 15 preliminary questions were selected. In addition, a preliminary scale was developed by modifying or adding items to conform to each constructive concept through expert content validity evaluation. Next, as a result of the exploratory factor analysis of about 250 adults, a three-factor structure model was derived. As a result of the confirmatory factor analysis on the preliminary scale for about 401 adults, it was confirmed that the fit of the three-factor structure was good. As a result of convergence and discriminatory validity analysis, it was confirmed that the developed scale was a valid tool to measure Kkondae by showing appropriate correlations with listening attitude, empathy, acceptance of others, and intellectual humility. Finally, based on the results of this study, the significance, limitations, and future research direction of the study were discussed.

In automatic map generalization, the formalization of cartographic principles is important. This study proposes and evaluates the selection method for road network generalization that analyzes existing maps using reverse engineering and formalizes the selection rules for the road network. Existing maps with a 1:5,000 scale and a 1:25,000 scale are compared, and the criteria for selection of the road network data and the relative importance of each network object are determined and analyzed using $T{\ddot{o}}pfer^{\prime}s$ Radical Law as well as the logistic regression model. The selection model derived from the analysis result is applied to the test data, and road network data for the 1:25,000 scale map are generated from the digital topographic map on a 1:5,000 scale. The selected road network is compared with the existing road network data on the 1:25,000 scale for a qualitative and quantitative evaluation. The result indicates that more than 80% of road objects are matched to existing data.

The paper proposes a knowledge innovation performance model by the dynamic data envelopment analysis with slacks-based measure approach for evaluating the effectiveness of 30 regional knowledge innovation activities in China from 2010 to 2016. In recent years, China has paid more attention to knowledge innovation activities, as central and local governments have pushed on with their innovation projects by lots of investment whatever the difficulties may be. Decision-maker is usually interested in judge its knowledge innovation performance relative to target benchmark by exploring whether one provincial administration region performs better among others and/or if the growth of economy will be benefited greatly by the knowledge innovation activities. To acquire the managerial insight about this issue from a comprehensively designed performance evaluation model, knowledge innovation activity is conceptualized as an intertemporal production process. Invention patent and regional gross product are imposed on desirable outputs, highlighting the need for knowledge economy. The empirical result shows that knowledge innovation has a positive effect on economic development. At the same time, decision-maker should be interest in the economic effect of patents' type and quality. The government should then encourage new technical applications with greater commercial value from a market-oriented perspective, in order to benefit the most from the innovation process in the short-run.

Fitness of clothes becomes a major concern in apparel industry. Development of basic patterns will enhance the fitness of clothes. But there are few slacks patterns for the middle-high school girls. So girls had difficulties to buy ready-made clothes of good fit. To solve this problem, it is necessary to develop basic slacks patterns. The purposes of this study was to develop basic slacks patterns based on the analysis of lower body types. 4 girls were selected among 402 anthropometric measurement subjects who are 13 to 15 year-old for the wearing tests. The result of this study can be summarized as follows; 1. Analysing the replicas of lower body surface by using gypsum method, slack patterns were developed. 2. Wearing test by the sensory evaluation showed that the developed slacks pattern was estimated more highly than existing patterns in the items of the comfort of front crotch and back crotch. 3. Wearing test by moire topography method represented that garment silhouette of developed slacks pattern was estimated more highly and garment space of waist, hip were significantly different among patterns.

Cyber security evaluation is a series of processes that estimate the level of risk of assets and systems through asset analysis, threat analysis and vulnerability analysis and apply appropriate security measures. In order to prepare for increasing cyber attacks, systematic cyber security evaluation is required. Various indicators for measuring cyber security level such as CWSS and CVSS have been developed, but the quantitative method to apply appropriate security measures according to the risk priority through the standardized security evaluation result is insufficient. It is needed that an Scoring system taking into consideration the characteristics of the target assets, the applied environment, and the impact on the assets. In this paper, we propose a quantitative risk assessment model based on the analysis of existing cyber security scoring system and a method for quantification of assessment factors to apply to the established model. The level of qualitative attribute elements required for cyber security evaluation is expressed as a value through security requirement weight by AHP, threat influence, and vulnerability element applying probability. It is expected that the standardized cyber security evaluation system will be established by supplementing the limitations of the quantitative method of applying the statistical data through the proposed method.
