The purpose of this study was to examine the current interior conditions of Child Care Center and to suggest the interior planning guidelines of Child Care Center. Data were collected through questionnaire survey including observations and interviews. The sample consisted of 84 Child Care Centers. The data were analyzed by using SPSS-PC. The major findings were as follows: (1) Most of Child Care Centers are not in the desirable Interior environment. To enhance the quality of Child Care Center, the physical interior environment of Child Care Center should be influence on the development of child. (2) Functional spaces should be organized to support the child' behavior. Multi-purposed room should be provide to encourage and adapt to variety of large-muscle activities. (3) The design of Child Care Center should be emphasized to satisfy teachers and children who are directed users. (4) Interior finishings looks too monotonous and do not have characteristics. Natural materials, various colors and patterns are recommendable. Furniture should be designed to meet the functions of flexibility, mobility, and security.

Transparent conductive alum mum-doped ZnO (AZO) films have been prepared on polycarbonate (PC), Coring 7059 and Quartz substrates by DC sputtering method at room temperature. Films deposited was evaluated about spectra of X-ray diffraction and transmittance and characteristics of films deposited as kind of substrate was compared. Films deposited showed (002) orientation and all AZO films are transparent over 80% within the visible wavelength region.

The ITO thin films were prepared by FTS (Facing Targets Sputtering) system on polycarbonate (PC) substrate. The ITO thin films were deposited with a film thickness of 100nm at room temperature. As a function of sputtering conditions, electrical and optical properties of prepared ITO thin films were measured. The electrical and optical characteristics of the ITO thin films were evaluated by Hall Effect Measurement (EGK) and UV-VIS spectrometer (HP), respectively. From the results, the ITO thin film was deposited with a resistivity $8{\times}10^{-4}[{\Omega}-cm]$ and transmittance over 80%.

Integration and standardization of the related regulations and guidelines are necessary to evaluate a CFMS in a systematic manner. In this study, a hierachically categorized evaluation checklist was developed by collecting and structuring human factors issues listed in the various regulations, design requirements, and technical report. A PC-based database management system was developed to update and review the evaluation results. Standard interpretation examples, evaluation guidelines, and sample evaluation formats were also designed and integrated into the database system to reduce discrepancy in evaluation.

Photovoltaic effects in organic solar cell were studied in a cell configuration of ITO/PEDOT:PSS/CuPc(20 nm)/$C_{60}$(40 nm)/BCP/Al(150 nm) at room temperature. Here, the BCP layer works as an exciton blocking layer. The exciton blocking layer must transport electrons from the acceptor layer to the metal cathode with minimal increase in the total cell series resistance and should absorb damage during cathode deposition. Therefore, a proper thickness of the exciton blocking layer is required for an optimized photovoltaic cell. Several thicknesses of BCP were made between $C_{60}$ and Al. And we obtained characteristic parameters such as short-circuit current, open-circuit voltage, and power conversion efficiency of the device under the illumination of AM 1.5.

Despite the government's various safety measures, the number of safety accidents continues to rise and the interior is more likely to occur indoors than outdoors. Safety accidents involving young children account for more than 70 % of the safety accidents in the safety accidents, and the ratio of safety accidents in the classroom or classroom is more than 50 %. In this thesis the author proposes the system managing the accidents notification service using LED lighting and access entry control. Utilizing IoT technology, remote control or access can be controlled remotely by controlling multiple lights and entrances from each room and by means of a number of lighting and entrances. By monitoring and analyzing real-time status via server PC and mobile interface, it can control the maximum control and incident prevention, automatic control, and automatic control.

In recent years, the use of touch screens has expanded, and devices such as remote controllers have been developed in various ways to control and access contents at long range. The wireless-based touch screen is used in classroom, seminar room, and remote video conversation in addition to the TV remote control. The purpose of the study is to design a smart phone-based intuitive interface that can perform the role of a wireless mouse and a wireless keyboard at range using Bluetooth and to develop an application that integrates functions of a mouse and a keyboard. Firstly, touch interaction model for controlling software such as PowerPoint by connecting to a general PC on a smart phone has been studied. The most simple touch operation interface is used to reproduce the function of existing devices and design more simply. The studies of the extension of interfaces with various functions are important, but development of optimized interfaces for users will become more important in the future. In this sense, this study is valuable.

최근 방 탈출 게임이 두뇌 활성화에 도움이 된다고 알려지면서 유행이 되었다. 하지만 PC, 모바일의 경우 몰입도가 떨어지고, 현실의 경우 시간과 장소의 제약이 생긴다. 이러한 제약 요소를 해소하기 위해 기존의 방 탈출 게임과 VR기술을 접목시킨 몰입형 미션 시뮬레이션 게임을 기획하게 되었다. 본 논문에서는 VR 방 탈출 시뮬레이션 게임을 제작하기 위해 사용된 S/W와 H/W 구성도, 기능 및 시스템 시나리오 그리고 게임을 통해 얻을 수 있는 기대효과를 4가지 유형으로 기술하였다.
