Currently, obtaining information about the housing studies through the internet web sites is one of the outstanding mediums. Those are of the housings, architecture, interior design, furniture products, hotels and its journals, etc., and out of all those informations are the highly expected value of use. But. it may causes the public users to experience a negative effect, because many of those informations provided on the internet web sites related to the housing studies/informations are not providing an equal quality of information. And measuring the quality is also not easy. This study focuses on the establishment of evaluation criterion for the housing information-related internet web sites. In such a vein, it proposes a clear model to evaluate the information qualities with the 43 questionnaires / examining items. To test the questionnaires/rating items, the analysis has been implemented which has shown the reciprocal effect between the 2 major factors. One major factor with 4 variables on the information searches are (1) the accuracy/reliability of contents and techniques, (2) the design of a picture and communication, (3) the readability and security, and (4) the security of private information, and the other factor with 3variables on the additional services are (1) the diversities of contents and ease of orderings, (2) the abilities of search and e-mail, and (3) the events and after services. This study/rating model will provide the users with a fundamental material in evaluating the quality of housing information on the internet web sites.

The study was carried out to investigate on the response of environmental sanitation problems in action of the volume based waste charge system in Seoul. The responses from the 396 persons who dwelled in Seoul was stimulatively answered, this system was considered as a successful one 69.6% of total answers, but little portion (21.2%) of those was unknown on the mean of this system. And we knew that this system was need to the communication and education through the press media about this one. After the action of the volume based waste charge system, the volume of refuse discharged in a day was decreased 30-50% than before. In the problems of environmental sanitation after this system, the number of sanitary insect(cockroach etc) and rat was decreased, also the production of order and dust caused by refuse was decreased in comparison with those before. This results were considered that the Separate Collection should be perfectly performed. In response, the regular envelope of refuge was serious problems, the improvement for this one was demanded, The kind of difficult refuse treated was waste foodstuffs> electric products> rubbers> furniture> bottles, cans>papers, pulps etc. and the next proposal for this system should be prepared. Conclusively, the volume based waste charge system should be remarkable system in terms of resources recycling as well as wastes reduction. Above all in order to conform this system the separate collection system should be systematically performed, the next improvable proposal of the detailed methods in this system should be prepared.

가사도우미 로봇과 같은 서비스 로봇은 가사구성물이 내제된 가정 내 가사 구성물 환경을 인식해야한다. 기존에는 홈서비스 로봇 등은 CCD, 초음파 등의 센서로 가정 내 구성물 및 실내 지형을 인식하였다. 실내지형 지도를 작성 할 경우 가사 구성물에는 헝겊 등이 있는바, 음파 등을 흡수하여 정확한 지형 지도가 만들어지지 못한다. 또한 CCD 카메라를 쓸 경우 pixel에 따라 거리 측정 정도가 달라지는 문제가 발생하고 가격이 고가이다. 본 논문은 이동로봇을 위한 위치 및 물체인식용 지능형 센서 제어 시스템에 대해 기술한다. 개발된 센서제어시스템은 저가의 광 PSD(Position sensitive detector)를 사용하였다. PSD센서의 스위칭 노이즈 및 광 산란에 의한 잡음을 효과적으로 제거하기 위해 로봇의 주행 중 센서 스캔 시 간 등을 고려하여 heuristic software filter를 제안하였다. 또한 개발된 시스템은 초음파 센서에 의한 지형작성 비교와 본 논문에서 개발한 시스템을 비교하였으며, 복잡한 실내지 형을 대상으로 실험 지형지도 작성 실험을 통해 우수성을 입증하였다.

The study is aimed to analyze cases of hotel room designs based on the 'Art Quotient'. It is focused on design elements of livability, analyzing the space design in terms of biophilic design and experiential marketing. This paper proposes a direction for hotel design based on the analysis result. The scope of the study includes the cases of 17 hotels in the area of Seoul achieving five stars in Korea. This paper presents an analysis whether the room space of hotels provide a user-oriented life experience from the perspective of biophilic design and experiential marketing. In this study, we focused on the concept of 'refuge', one of the biophilic design elements that express the value of life sense, and the element of 'sense', one of the strategic experiential modules of experiential marketing. After analyzing the hotel case studies, the space was evaluated using five factors of art quotient as a design method to provide a life experience in the hotel room. Analysis of the design space from the viewpoint of refuge, rather than architectural elements, proved that decorative elements appeared most commonly in all hotel rooms. Further, through an analysis based on the measures of 'sense', an experiential element, visual elements were mostly enforced in among the elements of the five senses. In other words, when designing a hotel room space, visual elements such as color, pattern, furniture, lighting and style are mainly utilized. Examining the analysis of the design elements from the point of view of the art quotient, the rooms of all the hotel's suite types include elements of 'communication'. Most of the hotel rooms focused on stimulating the aesthetic sensibility of customers. This resulted in the elements of 'immersion' showing poor results. In conclusion, it is necessary to provide the five senses of the arts index in a balanced manner to provide a life experience through the five senses.

This study examines attributes and expression characteristics of 'Mix & Match' which is one of the major current trends in interior designs. The concept and background of 'Mix & Match' was ascertained through research of previous documents and studies, and its attributes were explored. In order to examine the expression characteristics to see how they are expressed in actual interior designs, case analyses were carried out centering on the expression elements such as material, light & lighting, color, furniture and objects which were regarded as important in previous studies and related articles so far. The case analyses were carried out for works where the concept of 'Mix & Match' was prominent in designs produced in 2007 and 2008, chosen from the main reports of the representative interior design journals, 'Interiors' and 'INTERNI & Decor'. As a result, it has been found that 'Mix & Match' is not limited to one attribute but the temporal, spatial and genre attributes are present all at the same time, or various expression elements exist in one attribute. This is a distinct character commonly shown in most of the cases and each expression element is expressed in variety according to spatial concept, from a simple parallel to substitution, transfer and modification (simplification, transformation of the scale, rate modification etc.) Therefore, in creating the space for 'Mix & Match' or in interpretation of it, the understanding of these expression characteristics would make it possible for clearer and more various applications of design, and furthermore will be meaningful for supply and accumulation of reference in design communication.
