Recently, in the elevator of the buildings, such as apartment and office building, the visitor monitoring cameras for surveillance, advertising LCD to provide a variety of information, emergency call devices, and safe driving information sensors are installed. A variety of multimedia data from these devices to the central control office, management office, or to guard room are transmitted in real-time. Each sub-systems in the elevator are installed with a separate lines and operated independently and use different management principals, so integrated management for each sub-systems are very difficult. In this study, we develop a new IP-based multi-channel video surveillance system which is integrated surveillance camera, emergency call devices, communications devices, various sensors in the elevator, DVR, ODM, and can manage all devices by two-way communication and integrated interface. And we evaluated the performance of the developed system.

A space launch vehicle system represents a typical example of large-scale multi-disciplinary systems, consisting of subsystems such as mechanical structure, electronics, control, telecommunication, propulsion, material engineering etc. A lot of cost is required to develop the launch vehicle system. A precise planning of R&D cost is very essential to make a success of the launch vehicle development program. Especially in the early development phase of a new space launch vehicle system, cost estimation techniques and analogy from past similar development data are very useful methods to estimate a development cost of the launch vehicle system. Now Korea Aerospace Research Institute is in charge of the KSLV-I (Korea Space Launch Vehicle-I) Program that is a part of Korea National Space program. KSLV-I Program is a national undertaking to develop launch capabilities to deliver science satellites of a 100kg-class into a low earth orbit. It is hereafter, going to plan to develop a new korean space launch vehicle. In this paper, first the development costs of well-known launch vehicles in the world are presented to provide a reference to make a development plan of a new launch vehicle. Second this paper introduces the present status of cost estimation applications at NASA. Finally this paper presents the results from application of a TRANSCOST, a parametric cost model, to derive a cost estimate of a new launch vehicle development, as an example.

Korea Government have carried out various policies to save the Earth environment from global warming and environmental pollution. It has also executed the Green Building Certification Criteria(GBCC) in 2002. The GBCC of office building was executed in 2003 and was revised twice in 2010 and 2011. Concerns about green building construction were quite increasing to keep the building performances sustainable. The aims of this paper is to check the reliability of weighting factors and scoring difficulties in all assessment categories of GBCC and to suggest the amendment direction of the future assessment criteria for green building. For the study, the old and new version of GBCC were examined to present the revision direction of GBCC and the 10 cases certificated by the old and new version, respectively 5 were analysed to compare with the difficulties in obtaining the certification. According to the results of the study, the GBCC requires additional amendments about the assessment categories of the energy consumption monitoring and the building commissioning as required subjects in order to secure the building performances. In addition, the operation mamagement of the building need to be assessed more intensively.

Since the supply of smart phones, a change in mobile environment brought a turning point called a mobile generation. Smart mobile office is a combined form of smart phones' new mobile environment and its social media. A construction of mobile office environment using smart phones brought revitalization of the smart phone market. CRM construction also became new requirements for a customer management. However, based on the current information system audit standard, check fields or check lists are insufficient to apply to audit for CRM construction in a smart mobile office environment. Therefore, this paper proposes a model for auditing CRM system construction in smart mobile office environment. It proposes audit domain and check lists of CRM construction. It also verified whether the proposed model is suitable or not by doing a survey if deduced audit domain and check lists correspond with the purpose of the CRM construction audit during smart mobile office environment. As the result, this study appear to have more than average satisfaction the suitability results were.

The purpose of this study is to investigate that which Goon office buildings were reused from existing buildings and to identify remodeling and extension ways of the reused to match Goon's administration work. This study used literature research method, i.e., analysing the digital images, the annotation, and the official documents between the Japanese government-general of Korea and To(道), and articles of newspapers and journals. The reused were governmental offices of Joseon(朝鮮) dynasty, existing Goon office buildings of Korean empire government and old buildings with unknown purposes. They were remodelled and extended to match Goon's administration work. Common remodelling was making large space with desks for civil petitions and projecting an small entrance from the center of main building's facade. Common extension was constructing accessory buildings with simple wooden structure, locating them to back or side of the reused, and connecting them through external corridor. As many as 30% of 218 Goon office buildings were reused. About 57% of them were replaced as new office buildings, however the number of the new was rapidly decreased after mid 1930s.

The office-based, un-sedated vocal fold injection laryngoplasty has re-emerged in the past decade as an appealing alternative to microsuspension laryngoscopic procedure which is conducted under general anesthesia. The trend toward vocal fold injection laryngoplasty in an in-office setting was possible due to technological evolution for visualization and new injection materials. However, invisibility of the injection needle has been the main shortcomings of cricothyroid approach. The purpose of this review is to provide an up-to-date review of office-based, trans-cricothyroid membrane approach injection laryngoplasty technique under local anesthesia and efforts made to increase the preciseness of amount and location of the injected materials in the management of glottic insufficiency. A review of variable efforts undertaken to maximize the result of cricothyroid approach by technically increasing accuracy of the location of needle tip was done. With the proper patient selection and utilization of the new technologies, office-based and un-sedated vocal fold injection laryngoplasty via cricothyroid approach can be redeem as a main-stay in the management of glottic insufficiency, such as vocal fold paralysis, vocal fold paresis, vocal fold atrophy and vocal fold scar.

Namhansanseong fortress (南漢山城) is not Eupchi (邑治) created for ages but the new settlement of public and military administration as Baedo (陪都) to defend capital territory. Namhansanseong has Jinsan (鎭山) that is named Cheongnyangsan (淸凉山) and its government office building was located in the main place, also a periodic five-day market was being held in the center of fortress. This study is find out the transition and its historical background of government office building on Namhansanseong by the relocation of Eupchi in the 17th century. The conclusion of analysis can be summarized as follows; The main change of government office in the late Choson dynasty is to move Yi-a, administrative complex (貳衙) around Yeonmugwan (演武館). Since 1795, the 19th year of King Jeongjo (正祖), this was fixed by the end of the Choson dynasty on the unification of Magistrate which is also Defense Commander. In the second place, the military office on Jungyeong (中營) that is Junggun's (中軍) place of work was abolished by the reform of Junggun system. Thirdly, transition of the end of the Choson dynasty is the abolition of Sueoyeong (守禦營) and the realignment of government offices. Namely, the administrative agency was moved to Haenggung (行宮) after the collapse of unification in 1895. Also former military offices was changed to police administration on Gwangju-bu (廣州府), Gwangju county level unit.

MS Office suit software is the most widely used electronic documents by a large number of users in the world, which has absolute predominance in office software market. MS Office 2007-2013 documents, which use new office open extensible markup language (OOXML) format, could be illegally used as cover mediums to transmit secret information by offenders, because they do not easily arouse others suspicion. This paper proposes nine forensic methods and an integrated forensic tool for OOXML format documents on the basis of researching the potential information hiding methods. The proposed forensic methods and tool cover three categories; document structure, document content, and document format. The aim is to prevent covert communication and provide security detection technology for electronic documents downloaded by users. The proposed methods can prevent the damage of secret information embedded by offenders. Extensive experiments based on real data set demonstrate the effectiveness of the proposed methods.
