This paper proposes a method for generating radar images used in a ship handling simulator, which includes mathematical logics based on radar equations and information from Openflight format files. In order to make radar image much similar to that of real radar in PPI type, the proposed mathematical logic derives radar video signals under the consideration of not only the data form flight format file of simulation scenes, but also geographical radar's position. The proposed method is considered useful to make radar images in ship handling simulator with accuracy and reality.

Most product structural components are assembled by various members and castings except casting products. In such cases, a particular structure is required to move and fix each component. In particular, the safety uncertainty of heavy product assemblies can be linked to large accidents. Thus, the safety design and evaluation of additional structures have become more important. In the field and factories, these additional structures are called handling structures, which are designed and manufactured. As the types of products produced become more diverse, the design and manufacture of a handling structure are also diversified. The results of each evaluation should be derived. We develop a logical design and evaluation method, which was previously designed based on empirical data, for the handling structure.

This study is to categorize five types of conflict handling styles that employees can take when conflict occurs. The five types are integrating, avoiding, dominating, obliging, and compromising. I found these factors that explain conflicts handling styles divided them into organizational structure, task group functioning and need styles and how certain factors explain different kinds of conflict handling styles without other factors. To measure conflict handling styles, this study used the scale of conflict style devised Rahim. Data were collected by the survey method from employees engaged in the service industry located Seoul, the Province of Gyeonggi, and the Province of Gangwon. In addition, in order to prove my hypothesis, I used hierarchical regression analysis method to find the pure explanation that each factors have without multicollinearity. According to the study's result, in a person's type of needs, if the need for achievement is high, they prefer integrating style. In contrast, if the need for achievement is low, they prefer avoiding style. Also, if the need for affiliation is high, the employees prefer compromising style. But if the need for affiliation is low and the need for dominance is high, the employees favor dominating style. However, in task group functioning, group homogeneity, group cohesiveness, and group goal clarity are high, or the confidence in peers and management is high, the employees prefer obliging style to other conflicts handling styles. As well as if group homogeneity, group cohesiveness, and group goal clarity are high, it was found that they prefer compromising style. Also, if the role conflict that is related to organizational structure is serious, employees prefer obliging style, but they have weakenss in explanation. To sum up these results, if the employees have obliging style that shows lack of concerns over themselves and at the same time, have high concerns to others, is affected by task group or organization. And we can infer that the other conflicts handling styles are effected by personal characteristic.

The data of average temperature, average relative humidity, precipitation and average wind speed were collected from 674 meteorological stations in China. A specific procedure that processes original data into a new data format needed in forest fire danger rating forecast system of China was introduced systematically, and the feasibility of this method was validated in this paper. In addition, a set of meteorological data processing software was constructed by the secondary development of GIS in order to realize automation of processing data for the system. Results showed that the approach preformed well in handling temperature, average relative humidity and average wind speed, and the processing effect of precipitation was acceptable. Moreover, the automated procedure could be achieved by GIS and the working efficiency was about 3 times as much as that of manual handling. The informationization level of processing meteorological data was greatly enhanced.

설문조사를 실시할 경우 무응답이 발생하지 않는 경우는 매우 드문일이며 무응답이 발생할 경우 무응답처리에 대해서는 다양한 방법이 적용되고 있다. 본 논문에서는 무응답의 두 가지 유형인 단위무응답과 항목무응답의 발생비율을 기존에 조사된 실제 사례를 이용하여 파악하였으며, 무응답률에 따른 분석결과의 차이를 비교하였다. 또한, 대학생들을 대상으로 집단면접조사를 통해 직접 자료를 수집하였고 이 자료를 바탕으로 무응답률과 무응답이 발생하는 이유를 제시하였다.

Until now, considerable progress has been made in the application of range finding techanique performing direct 3-D measurement from the object. However, ther are few use of the method in the area of the application of material handing. We present a range finding vision system consisting of static and dynamic range finders to automate a reclaimer used for material handling. A static range finder detects range data of the front part of the piles of material, and a height map is obtained from the proposed image processing algorithm. The height map is used to calculate the optimal job path as features for required information for material handling function. A dynamic range finder attached on the side of the arm of the reclaimer detects the change of the local properties of the material with the handling function, which is used for avoiding collision and detecting the ending point for changing direction. the developed vision systm was applied to a 1/20 simulator and the results of test show that it is appropriate to use for automating the material handling.

The focus of this study was on service recovery process of domestic internet fashion shopping mall, the purposes of this study were to extract perceived interaction effort and service justice with the recovery factors according to service failure by literature review, and to empirically examine the effect this variables on customer satisfaction with complaint handling and loyalty. The questionnaires was administered to 256 internet shopping mall customer, who has experiences of dissatisfaction and complaining behavior after buying fashion products. The data was analyzed by Cronbach's a, confirmatory factor analysis, correlation analysis, and structural equation modeling using LISREL 8.30 program. The results were as follows. First, perceived interaction partly affected serviced justice consumer. Interaction effort on the part of consumer negatively affected interactional justice, but didn't affected distributive justice and procedural justice. However interaction effort on the part of shopping mall positively affected all justice. Second, distributive, procedural and interactive justice positively affected customer satisfaction with complaint handling and loyalty. Finally, customer satisfaction with complaint handling positively affected customer loyalty. The implications of the research and directions for future researchers were discussed.

IoT 환경에서 센싱 정보의 활용을 위해서는 센서로 부터 생성된 정보의 가공 및 처리를 위한 효율적인 소프트웨어 아키텍처 설계가 필수적이다. 특히 IoT 환경에서 사물은 인터넷에 연결되고 각종 센서를 탑재한 디바이스간 통신이 가능하여야 한다. 그러나 MapReduce 기반의 Hadoop과 Twister은 데이터의 배치 처리에 적합하지만, 스트리밍 센서 자료의 이동중 처리에는 제약점을 갖는다. 전통적인 스트리밍 데이터 처리 방법인 MOM 기반의 메시지 큐 시스템을 이용해 메시지 스트림을 처리하는 방식은 프로그래머가 메시지 흐름의 복잡도를 고려해야 상세한 처리를 프로그램 함으로써 유지보수 및 확장성을 갖기 어려움이 있다. 이 논문에서는 IoT 환경에서 수집된 센싱 자료의 처리를 위한 소프트 웨어 아키텍처를 설계하였다. 또한 설계된 소프트아키텍처를 기반으로 오픈소스 프레임워크인 Storm의 응용 구성을 기술한다. 구성응용은 센서게이트웨이(Sensor Gateway)를 통해 자료를 수집한 후 실시간 스트리밍 데이터를 파이프-필터 스타일로서 변환한다.
