  • The purpose of this paper is to promote the usage of facade greenery in order to improve the quality of life in cities and to improve their ecological worth. It is necessary to find out what people think about facade greenery, what problems they think, they might encounter and to promote the use of facade greenery. The survey was grouped according to three housing types; family house, tenement house and apartment. We distributed questionnaires individually to 140 people in each of the three housing types. All 420 people answered. The major questions in the questionnaire relate to the following issues: opinions about facade greenery, opinions regarding reasons to install facade greenery and expected problems, favourite plants, and to provide an analysis of the current usage of facade greenery. The results of this study show that most people like facade greenery and revealed that there was a significant difference in the kinds of responses from the three types of housing. The most important factor to affect respondents' positive preference for facade greenery is that it provides opportunities to experience nature near the housing and the improvement of the aesthetic appeal of facades for those living in apartment housing. Negative responses were based on the inhabitation of insects, and the difficulties in maintaining facade greenery. The favourite plants are parthenocissus and climbing rose. Generally people were lacking in an understanding of the ecological value of facade greenery. Most of the respondents indicated a liking for facade greenery and so the situation is now suitable to promote it.

  • When entering the PIN(personal identification number), the greatest security threat is shoulder surfing attack. Shoulder surfing attack is watching the PIN being entered from over the shoulder to obtain the number, and it is the most common and at the same time the most powerful security threat of stealing the PIN. In this paper, a psychology based PINpad technology referred to as DAS(Dynamic Authentication System) that safeguards from shoulder surfing attack was proposed. Also, safety of the proposed DAS from shoulder surfing attack was tested and verified through intuitive viewpoint, shoulder surfing test, and theoretical analysis. Then, a PINpad with an internal DAS that was certified for its safety from shoulder surfing attack was designed and produced. Because the designed PINpad significantly decreases the chances for shoulder surfing attackers being able to steal the PIN when compared to the ordinary PINpad, it was determined to be suitable for use at ATM(automated teller machine)s operated by banks and therefore has been introduced and is being used by many financial institutions.

  • A postharvest treatment called CATTS (controlled atmosphere and temperature treatment system) has been used as an alternative nonchemical measure for methyl bromide fumigant treatment. This study applied CATTS to control the red flour beetle, Tribolium castaneum, infesting stored grains. Adults of T. castaneum were susceptible to $46^{\circ}C$ heat treatment. The susceptibility was further enhanced by addition of CA conditions (15% $CO_2$ and 1% $O_2$). When CATTS ($46^{\circ}C$, 15% $CO_2$, $16^{\circ}C/h$ treating rate) was applied to different developmental stages of T. castaneum, it showed 100% control efficacy by 120 min exposure. There was a variation in CATTS susceptibility among developmental stages, in which late instar larvae were most tolerant. Heat shock proteins of T. castaneum appeared to be implicated in the tolerance of CATTS.

  • The space designated for kindergarten and elementary school students, who accounted for half of all users of the presidential archives, is now lacking, with the archives' programs focusing on exhibitions and field trips. With this, an experience exhibition is seen as the most effective way to communicate the value of presidential records and archives based on the theory of cognitive development. Therefore, this study proposes an experiential exhibition program for children about presidential archives based on the experience economy under theories that are recently getting attention. The Presidential Archives through the Experiential Exhibition program for children proposed by this study will become a place for the cultural communication of all generations.

  • The study aims to identify the problems of the research support service in presidential archives for users who use archives for scholarly purposes. For these purposes, the study conducted a literature survey. Moreover, this study compared and analyzed the content of presidential archives' Web sites between the U.S. and Korea. In addition, we examined the interviews via e-mail with an archivist working in the presidential archives in the U.S. and gained the materials from the presidential archives in Korea through a request of information disclosure. It was found that six improvements were considered by academic users to meet their needs. Consequently, based on the analysis, a research support services framework consisting of a service category was developed. With the proposed services, the academic utilization of presidential archives can be facilitated.

  • Traditionally, archives, libraries, and museums have been known to have common responsibilities in providing public service, despite of their differences in the nature of holdings. Recently, these institutions, which are keeping archival materials, increasingly collaborate with each other to provide effective integrated user service in educational programs. The study highlights the importance of collaboration among cultural institutions and analyzes the exemplary cases inside and outside Korea. By analyzing the current educational services conducted by the institutions, focusing on weaknesses and strengths, the authors mention that the analysis results can be referred to them when developing a model of educational services. Based on the analysis, this study finally offers a plan to activate the collaboration of cultural heritage institutions in Korea and develop a model for educational services using the ADDIE model.

  • For the preliminary step for estimating the performance of roof-type photovoltaic system in urban areas, we analyzed the solar radiation reduction ratio by shadow effect by buildings using DSM (Digital Surface Model) and GIS (Geographical Information System) tools. An average loss by the shadow is about 19% in Seoul. The result was related to the building density and distribution. Monthly results show that the winter season (December and January) was more affected by the shading than during the summer season (June and July). It is expected that useful empirical formulas can be made if more detailed correlation studies are performed.

  • 오늘날 기업간 M & A가 활발히 진행되면서 브랜드 자산가치에 대한 연구는 학계와 실무계에 있어 커다란 관심이 집중되면서 브랜드의 역할에 대해서 다양한 새로운 관점이 제시되고 있다. 브랜드 자산가치와 관련한 기존의 연구들은 주로 평가에 관한 것이 대부분이었으나 최근에 와서 브랜드 자산가치의 중요성이 부각됨으로써 브랜드 자산가치의 형성에 대한 영향요인의 연구가 활발히 이루어 지고 있다. 하지만 이틀 연구의 대부분은 제품 품질과 광고톨 중심으로 한 기업의 통제 변수인 마케팅믹스-4P(product, price, place, promotion)-에 연구의 초점을 맞추고 있다. 하지만, 오늘날 기술혁신에 힘입어 규모의 경제성이나 경험효과에 의한 비용 우위는 거의 기대될 수 없게 되었고, 품질에서도 기업간의 격차가 현저히 줄어들었다. 그러고 막대한 비용의 문제로 인하여 매스미디어등의 광고를 통한 브랜드 자산가치의 형성이 결코 쉬운 일이 아니다. 특히 오늘의 국내의 기업현실을 감안하면 더욱 어려운 실정이다. 따라서, 본 연구에서는 기존의 연구에서 다루지 않았던 고객만족 실현를 위한 핵심개념인 내부마케팅과 다양한 소비자 욕구에 있어 신속히 대응하는 브랜드 수의 증가를 브랜드 자산가치의 형성에 대한 새로운 영향요인으로 선정하여 마케팅믹스 요인과 더불어 이들의 영향성을 실증분석을 통하여 검증하였다. 본 연구의 결론을 이용하여 다음과 같은 브랜드 자산가치에 대한 마케팅에 있어서 전략적 시사점을 제안한다. 첫째, 브랜드 자산가치톨 형성 내지 강화하기 위해서는 내부마케팅 요인, 브랜드수의 증가요인, 마케팅믹스 요인중에서 어느 한 요인만으로 한계가 있기 때문에 3가지 요인을 동시에 활용하여 시너지 효과를 노려야할 것이다. 아울러 다양화, 세분화되어 가고 있는 소비자 니즈에 신속히 대용하기 위해서는 브랜드의 수의 증가를 통한 마케팅전략으로의 실천이 시의 적절한 방법중 하나라고 판단된다. 둘째, 기존의 많은 연구에서 알 수 있듯이 그동안 브랜드 자산가치의 구성요소에 대한 영향 요인으로 마케팅믹스적 요인을 주로 다루어 왔는데, 본 연구 결과에 의하면 내부마케팅요인과 브랜드수의 증가요인도 브랜드 자산가치의 구성요소에 많은 영향을 미치는 것으로 나타났기 때문에 기업들은 이들 요인에 대한 세밀한 검토와 관심이 요구된다. 셋째, 기업들은 향후 브랜드 자산가치를 증대하기 위한 장기적이고 전략적인 관리방안이 요구된다.

  • The application of CT with basis on 3 dimensional-reconstruction is getting more widely practiced. With the data obtained from cone-beam computed tomography(CBCT), not only the diagnosis of the patient with skeletal abnormality but also the virtual simulation of the orthognathic surgery were performed and its application would be popular in orthodontic field. We reported a case, a 19-year old man who was diagnosed mandibular prognathism and required orthognatic surgery. In this case, the virtual orthognathic surgery was simulated and surgical wafer was fabricated by using CBCT data. That wafer was applied the actual orthognathic surgery. After preoperative orthodontic treatment, we prepared surgery as follows. : (l)Acquisition of 3D image data, (2)Reconstruction of 3-dimensional virtual model, (3)Virtual model surgery, (4)Extraction of stere-olithographic image, (5)Check-up for occlusal interference, (6)Fabrication of surgical stent by stereolithography. Bilateral sagittal split ramus osteotomy was operated and used stereolithographic surgical stent. 1 month later, we superimposed CBCT datas of virtual surgery and that of actual surgery, and then compared the result. CT data's application for othognathic surgery yielded satisfactory outcomes.

  • FlexRay is a new standard of network communication system which provides a high speed serial communication, time triggered bus and fault tolerant communication between electronic devices for future automotive applications. FlexRay communication controller (CC) is the core of the FlexRay protocol specification. In this paper, we first design the FlexRay CC protocol specification and function parts using SDL (Specification and Description Language). Then, the system is re-designed using Verilog HDL based on the SDL source. The FlexRay CC system was synthesized using Samsung $0.35\;{\mu}m$ technology. It is shown that the designed system can operate in the frequency range above 80 MHz. In addition, to show the validity of the designed FlexRay system the FlexRay system is combined with sound source localization system in Robot applications. The combined system is implemented using ALTERA Excalibur ARM EPXA4F672C3. It is shown that the implemented system operates successfully.
