The "optimal" solution for a decision making problem should be the one that best reflects the decision-maker's preference. For MADM (Multi-Attribute Decision-Making) problems, however, finding an optimal solution is difficult, especially when the number of alternatives, or that of attributes is relatively large. Most of the existing mathematical approaches arrive at a final solution on the basis of many unrealistic assumptions, without reflecting the decision-maker's preference structure exactly. To remedy this, some interactive methods have been proposed, but most of them require a large amount of information growing exponentially as the number of alternatives, or that of attributes increases. Therefore it is difficult for the decision-maker to maintain consistency throughout the decision making process. In this paper, an interactive method which finds optimal solutions for deterministic MADM problems with many attributes and alternatives is proposed. Instead of considering all the attributes simultaneously, this method partitions all the attributes into several mutually independent subgroups and considers one of them at each of preordered steps, where the alternatives are eliminated until the optimal one is obtained. The efficiency of the method lies in the fact that the amount of neccessary information is reduced significantly, and even further if a suboptimal solution is acceptable to the decision-maker.ion-maker.

As the need for the integration of administrative datasets and address information increases, there is also growing interest in POI (Point of Interest) data as a source of location information across applications and platforms. The purpose of this study is to develop an alias database management method for efficient POI searching, based on POI data representing position. First, we determine the attributes of POI alias data as it is used variously by individual users. When classifying aliases of POIs, we excluded POIs in which the typo and names are all in English alphabet. The attributes of POI aliases are classified into four categories, and each category is reclassified into three classes according to the strength of the attributes. We then define the quality of POI aliases classified in this study through experiments. Based on the four attributes of POI defined in this study, we developed a method of managing one POI alias through and integrated method composed of word embedding and a similarity measurement. Experimental results of the proposed POI alias management method show that it is possible to utilize the algorithm developed in this study if there are small numbers of aliases in each POI with appropriate POI attributes defined in this study.

The purpose of this study was to compare and analyze the importance and satisfaction of consumer selective attributes by home meal replacement (HMR) types using local ingredients. This study was conducted from December 4 to December 8, 2020. A total of 380 responses organized according to preferred types of HMR (100 for Ready to Eat (RTE), 92 for Ready to Heat (RTH), 88 for Ready to Cook (RTC), 100 for Ready to Prepared (RTP) were used for the final analysis. Statistical analysis was conducted by descriptive analysis, paired t-test, and importance-satisfaction analysis by HMR type. Findings of this study showed significant differences in consumer selective attributes by HMR type. RTE and RTC need to improve quality while RTH needs to improve quality and packaging. Notable selective attributes were quality, packaging, and information. They were located in different quadrants of each HMR type. All other attributes appeared in the same quadrant. Further research is needed to determine differences in quality, packaging, and information for each HMR type. Results of this study provide basic data for developing products and marketing strategies for each type of HMR products using local ingredients.

Earthwork is an operation that provides space for structures, and it takes up a large portion of the construction costs in a construction project. In large-scale earthwork, numerous types of construction equipment are used in the operation. The types of equipment should be selected based on the field conditions and the construction methods. These construction vehicles are constantly changing positions during the earthwork operation. Therefore, the equipment operators require effective communication to ensure the efficiency of the earthwork operation. All equipment operators should exchange information with the other equipment operators. Information should be exchanged continuously to support decision making and increase productivity during the earthwork operation at the construction site. This paper investigates the attributes required for an information interface between construction vehicles during an earthwork operation. This paper 1) discusses the importance of an information interface for construction vehicles in order to increase productivity during an earthwork operation, 2) analyses the types of attributes that need to be communicated between construction vehicles, and 3) provides a database that has been built for attribute control. The database built for the information interface between construction vehicles will enhance communication between vehicle operators. Table I shows the typical attributes that should be shared between the excavator operator and the dump truck operator. This information needs to be shared among the operators, as it helps them to plan the earthwork operation in a more efficient manner. A database has been developed to store this information in an entity relation diagram. A user-interface display environment is also developed to provide this information to the operators in the construction vehicles. The proposed interface can help exchange information effectively and facilitate a common understanding during the earthwork operation. For example, the vehicle operators will be aware of the planned volume, excavated volume, transportation time, and transportation numbers. As a part of this study, mobile devices, such as mobile phones and google glasses, will be used as hands-on communication tools.

FRBR을 대체한 개념모델인 LRM 개발에 따라 목록원칙, 목록규칙, 입력형식 측면에서 LRM 수용 방안이 모색되어야 한다. 이에 본고는 BIBFRAME 측면에서 LRM의 표현형 및 대표표현형 속성 적용시 고려사항을 파악하기 위해 문헌연구와 전문가 면담을 실시하였다. 분석 결과 우선, BIBFRAME에는 표현형 개체가 없지만 BIBFRAME 저작에서 LRM의 저작과 표현형을 수용하는데, 이는 저작과 표현형을 각각 저작으로 보고 두 저작을 상호 연계하는 방식으로 표현형 개념을 유지하고 있다. 둘째, BIBFRAME에서는 대표표현형 속성과 이를 제공한 소스가 된 표현형을 연계하는 것을 고려해야 할 것이다. 셋째, LRM에서 저작 유형에 따라 대표표현형 속성의 내용이 달라지므로 BIBFRAME에서 대표표현형 속성으로 사용될 수 있는 언어, 연주매체, 대상이용자, 축척 등의 속성에 대한 클래스 변경을 고려해야 한다. 넷째, BIBFRAME에는 저작을 중심으로 다양한 표현형 간의 네트워크가 생성될 수 있도록 관계의 확장이 요구된다. 본고는 LRM과 BIBFRAME을 표현형 및 대표표현형 속성에 중심을 두어 비교 분석하였으나 앞으로 LRM에 따른 목록원칙 및 목록규칙과의 비교 연구도 필요할 것이다.
