This paper describes the automatic extraction of collocations based on corpus. The collocations are extracted from corpus using cooccurrence frequency and mutual information between words. In English, 5 types of collocations are defined. These collocations are transitive verb and object, intransitive verb and subject, adjective and noun, verb and adverb, and adverb and adjective. In this paper another type of collocation is recognized and extracted, which consists of verb and preposition. So 6 types of collocations are extracted based on corpus.

일반적으로 공공기관 혹은 다수의 이용자가 사용하는 화장실은 관리 상황은 열악한 편이다. 화장실을 관리하는 곳도 있지만 상황은 그다지 다르지 않다. 그래서 사용하는 사람과 관리하는 사람 모두에게 이로운 자동 물 내림 변기가 필요하다고 생각한다. 이미 시중에 나와 있는 많은 자동 물 내림 변기들이 있다. 하지만 공공화장실에서는 가격 등의 제약조건에 의해 많이 사용되지 않고 있는 실정이다. 본 연구에서는 아두이노와 pH센서를 이용하여 기존의 자동 물내림 변기보다 간단하고 저렴한 자동 물 내림 변기를 구현하였다.

Man-machine assignment problem with random service and processing times is considered in this paper. Assuming heterogeneous semi-automatic machines, the problem is dealt with as follow; 1. For the different type of machines that have probabilistics distribution of processing time and nan service time, man·machine assignment problem is solved by heuristic method using expected time value if machine. 2. Since each related time is a random variable, the performance of the optimal assignment obtained from the above method is verified through monte carlo simulation method. 3. The above procedures are programed by BASIC language to use easily and rapidly in the personal computer. The result of this study can contribute to productivity enhancement by increasing the efficiencies of both operators and machines.

Reengineering to object-oriented system is needed to maintain the system and satisfy requirements of structure change. Target systems which should be reengineered to object-oriented system are difficult to change because these systems have no design document or their design document is inconsistent of source code. Using design document to identifying objects for these systems is improper. There are several researches which identify objects through procedural source code analysis. In this paper, we propose automatic object identification method based on clustering of VTFG(Variable-Type-Function Graph) which represents relations among variables, types, and functions. VTFG includes relations among variables, types, and functions that may be basis of objects, and weights of these relations. By clustering related variables, types, and functions using their weights, our method overcomes limit of existing researches which identify too big objects or objects excluding many functions. The method proposed in this paper minimizes user's interaction through automatic object identification and make it easy to reenginner procedural system to object-oriented system.

In the paper, we propose the automatic generation method of digital elevation map based on contour map. The proposed method classifies contour data and non-contour data by thinning and labelling process of the contour line and then connects smoothly broken contour line by Bezier curve. Finally, the digital devation map is generated by the interpolation using the height data of the contour line. The proposed method can reduce vest effort, time and expense which is spend to make digital elevation map.

In this paper, the dedicated short range communication(DSRC) system which used as the automatic gate system(AGS) Donga Univ. RRC developed is applied to yard automation. We proposed the communication algorithm of between roadside equipment(RSE) and on-board equipment(OBE). We analyzed transmitted and received information, classification and feature of between OBE and RSE for automation of the container yard and unloading system.

Smart city is currently the main direction of development. The automatic management of instrumentation is one task of the smart city. Because there are a lot of old instrumentation in the city that cannot be replaced promptly, how to makes low-cost transformation with Internet of Thing (IoT) becomes a problem. This article gives a low-cost method that can identify code wheel instrument information. This method can effectively identify the information of image as the digital information. Because this method does not require a lot of memory or complicated calculation, it can be deployed on a cheap microcontroller unit (MCU) with low read-only memory (ROM). At the end of this article, test result is given. Using this method to modify the old instrumentation can achieve the automatic management of instrumentation and can help build a smart city.

A 2D barcode region localization system for the automatic inspection of a long distance logistics objects has been developed. For the successful 2D barcode localization, variance and frequency of the pixel distribution within average 2D barcodes is modeled and the average model of 2D barcode is combined with the corner features detection to localize the final 2D barcode candidates. An automatic 2D barcode localization software was developed with the multiple features mixture method and we tested our system on real camera images of several popular 2D barcode symbologies.

As pet- one-person households increase, conditions must be developed to be easy to manage, but are still slow. In the case of single-person households, they have difficulty in feeding their food in case of unexpected situations such as appointments and night shifts. The above works can be distributed remotely regardless of time and place through the application. In addition, the addition of automatic booking service makes it possible to provide more convenience and improve the conditions.

현재 소프트웨어 요구사항은 전체 소프트웨어 개발 프로세스를 거쳐, 완성된 제품 인도 시 인수 기준으로 작용한다. 그러므로 이런 요구사항은 개발주기 전체에 걸친 매우 중요한 관리 수단이다. 그러나 국내 다수의 중소기업은 이러한 문서화에 시간 및 비용이 부족하여, 개발 문서의 부재 혹은 코드와 문서가 불일치한 것이 현실이다. 이 문제를 해결하기 위해, 자동 프로젝트 문서 발생기(Automatic Project Document Generator)를 제안한다. 제안한 발생기를 통해 요구사항 스펙과 소스 코드 간 동기화로 요구사항 대로 개발이 진행되는지 확인 가능하다.
