  • The impact of adding additional Multi-Criteria Decision Analysis (MCDA) criteria is demonstrated because current research shows MCDA for flood damage has been applied using only a few criteria but for better results the MCDA approach needs to apply more criteria for evaluating the alternatives. By adding additional criteria into MCDA, the capability to make the best alternatives more diverse and show the decision maker more differences in the scores of the alternatives to allow the decision maker to discriminate is significantly improved. The target region for a demonstration application of the methodology was the Suyoung River Basin in Korea. The 1991 Gladys flood event and five different return periods were used as a case study to demonstrate the proposed methodology of evaluation of various flood damage reduction alternatives.

  • Recent economic and income growth in Korea has caused people to seek healthier and happier lives. Forests are seen as spaces that provide tourism and recreation. The Korea forest service and local governments are developing and designating recreational forests but previous studies on the subject have only covered customer satisfaction and how forests are used. As such, the current study aims to find issues with designation criteria for recreational forests used by Gwangju city in Gyeonggi province and suggest improvements to the system. Site E was deemed the most adequate in evaluations of five candidate site. The criteria used in the evaluations were problematic due to (1) a lack of differentiating power in evaluation items, (2) blanket coverage of score ranges, (3) a lack of additional points for special sites, and (4) unclear evaluation indices. Based on the identified issues, the current study suggests introducing additional points and clearly detailing evaluation indices and items to enhance the evaluation of recreational forest candidate sites.

  • As cities continue to expand and additional underground structures are constructed, a policy is being planned to expand addresses, which are national framework data. In this study, the application scope of a proposed 3D (three-dimensional) mixed-use complex space for assigning 3D addresses was defined, based on past research on 3D address systems and by analyzing related laws. Underpass shopping malls, underground walkways (excluding underground shopping malls), and 3D mixed-use transfer centers with a gross floor area of 2,000㎡ or more are connected with each space by underground walkways or public paths. In addition, the detailed space corresponding to the public space of the 3D mixed-use complex space was presented and distinguished from the space to which the detailed address is assigned. The criteria for setting the road section were presented based on the intermediate space, which is a characteristic of 3D mixed-use complex spaces. The proposed criteria were applied to the Express Bus Terminal station (3D mixed-use transfer center) and COEX mall (underpass shopping malls). Thus, the road section was set for an unfamiliar 3D mixed-use complex space. However, by applying the proposed criteria to various 3D mixed-use complex spaces, additional and detailed criteria for different cases should be prepared.

  • Purpose : As the number of the transportation poor has increased, the application of Universal Design on urban railway station has recently been focused. However, the current criteria used in domestic areas did not show the characteristic of facilities within urban railway station. Therefore, this study aims to explore the detailed criteria in applying ideas from Universal Design to sanitary facilities, especially toilets within railway station. Method : This study explores the criteria by evaluating findings from previous studies. First, the current situation of sanitary facilities in railway station is assessed. Then, the detailed criteria applicable to railway station toilets are concluded, by reviewing types of transportation poor and principles of Universal Design. Result : Findings from this study are as follows. First, the current criteria applied to railway station toilets lack ideas of Universal Design, so the better criteria applicable to sanitary facilities in railway station are necessary. Second, standard criteria used in domestic areas with newly additional criteria suggest that sanitary facilities should be established according to those criteria. Taken together, the better sanitary facilities should be provided to railway users through the application of Universal Design to railway station toilets. Implication : For the future users in railway station toilets, the additional research on types of diverse space and other sanitary facilities within railway station should have been continued.

  • Effective recommendation of similar business groups is a critical factor in obtaining market information for companies. In this study, we propose a novel method for enhancing similar business group recommendation by incorporating derivative criteria and web crawling. We use employment announcements, employment incentives, and corporate vocational training information to derive additional criteria for similar business group selection. Web crawling is employed to collect data related to the derived criteria from 'credit jobs' and 'worknet' sites. We compare the efficiency of different datasets and machine learning methods, including XGBoost, LGBM, Adaboost, Linear Regression, K-NN, and SVM. The proposed model extracts derivatives that reflect the financial and scale characteristics of the company, which are then incorporated into a new set of recommendation criteria. Similar business groups are selected using a Euclidean distance-based model. Our experimental results show that the proposed method improves the accuracy of similar business group recommendation. Overall, this study demonstrates the potential of incorporating derivative criteria and web crawling to enhance similar business group recommendation and obtain market information more efficiently.

  • Despite the new wave of diverse philosophical thoughts in nursing, the criteria for theory evaluation rarely incorporate the new thoughts in its realm. Especially, feminist thoughts, which have contributed to the development of nursing knowledge through incorporating diversities and complexities of nursing phenomenon and reflecting social, cultural, and historical contexts surrounding nursing encounters, were rarely incorporated into the evaluation criteria. In this paper, a feminist approach to theory evaluation is proposed based on a critical analysis of the existing evaluation criteria. First, a historical review of feminist thoughts is provided, and feminist principles across diverse groups of thinking within feminism are discussed. Then, theory evaluation criteria are historically analyzed and critiqued while considering the feminist principles. The critical points found in the currently available theory evaluation criteria include: (a) the evaluation criteria are based on objectivity, (b) they are ignoring gender differences; (c) cultural differences tend not to be seriously considered; and (d) contexts surrounding nursing phenomenon are rarely considered. Based on the critical points, four additional components for theory evaluation are proposed. The components are: (a) respect for subjectivity; (b) historical and sociopolitical contextual considerations; (c) gender sensitivity; (d) cultural competence; and (e) blueprint for action.

  • The purpose of this study is to construct the fundamental data for setting a valid viewpoint as the base of landscape planning and management practices. To do this, we analyzed the preceding dissertations and landscape plan reports which presented the selection criteria of viewpoint. 37 research samples containing the criteria of viewpoint were investigated. The selection criteria and trends of viewpoint were analyzed as follows : Firstly, by analyzing the preceding researches we were able to grasp the criteria that had been used to set viewpoint. Secondly, we investigated the differences in criteria of selecting the viewpoint according to the research type, research time and view object. Finally, we analyzed the trends of viewpoint selection criteria and classified the characteristics and selection criteria of viewpoint based on an overview of the research content. It can be concluded that the criteria of viewpoint are intimately linked to the view object, the purpose and role of viewpoint which is related to the landscape planning and management practices. According to this study, we can find that the selection criteria and trends of viewpoint have been used in the research related to the view plane following the 1990's. Hereafter, additional research and the comparisons with researches abroad is necessary to set the objective selection criteria of viewpoint.

  • Purpose: A large number of the mobility impaired have increasingly used the railway station, so the application of UD(Universal Design) on urban railway station has been interested. However, the current criteria used in domestic areas have concerned about the effective administration of railway station facilities rather than the needs of he mobility impaired. Of diverse facilities in railway station, the platform is considered as an important space due to many transportation users' riding or transfer in railway stations. Therefore, this study aims to explore the detailed criteria in adapting ideas from UD to platform within railway station. Methods: This study explores the criteria by evaluating findings from previous studies. First, all criteria related to platform in domestic and foreign areas are taken together and analyzed, and appropriate criteria first are established. Based on these, the current situation of platform facilities in railway station is evaluated. Then, the detailed criteria applicable to railway station platform are concluded, by reviewing types of the mobility impaired and principles of UD. Result: Findings from this study are as follows. First, the current criteria applied to railway station platforms lack ideas of UD, while the criteria used in foreign countries adequately reflect the ideas of UD on railway station platforms; therefore, the better criteria applicable to platform facilities in domestic railway station are necessary. Second, standard criteria used in domestic areas with newly additional criteria suggest that platform facilities should be established according to those criteria. Taken together, the better platform facilities should be provided to railway users through the application of UD to railway station platforms. Implications: For the future users in railway station platforms, the additional research on criteria of UD as well as diverse types of spaces within railway stations should have been continued.

  • The soundness of honeycomb core sandwich and laminate structure used for commercial aircrafts is generally evaluated with ultrasonic inspection because the inspection is most sensitive to planar surfaces which are perpendicular to sound propagation pass and reflects sound almost 100% to equipment. And most defects inherent in composite material curing process has good reflective surfaces. With all this advantage, unexpected obstruction to product and additional cost could be occurred when inappropriate accept/reject criteria is given. In this study the importance of inspection criteria will be discussed to show how inappropriate criteria cause unexpected results leading to high production cost and how much time must be spent to correct those improper criteria with an actual case occurred in Aerospace Division, Korean Air.
