최근 홈페이지 기반의 다양한 기능이 개발, 적용되고 있어 웹사이트 재구축시 기능 개선 등의 이유보다는 디자인 재구성을 통한 인터페이스 개선을 꼽는 경우가 대다수로 나타나고 있다. 본 논문은 디자인 변경을 위해 기능 전체를 재개발하는 것이 아니라 개발된 템플릿을 활용하여 인터페이스를 변경하는 방법을 제안하고자 한다. 이 방법은 웹사이트 재구축시 개발 기간의 단축, 비용의 절감, 필요 인력의 최소화 등의 이점을 얻을 수 있다.

국내 및 국외에서 많은 시뮬레이션 환경이 개발되어 다양한 시뮬레이터 개발에 활용되고 있다. 이러한 시뮬레이션 환경은 다양한 기능을 갖추고 있어 시뮬레이터 개발편의를 도모하고 있다. 이러한 시뮬레이션 환경에서는 시뮬레이션 스케줄링(Scheduling), 데이터베이스(Database), 모델 컴파일 그리고 디버거(모니터링 및 제어기능 툴)등을 제공한다. 이미 국내 및 국외 업체에서 시뮬레이션 환경이 개발되어 왔지만, 3차원적인 시뮬레이션을 필요로 하는 시뮬레이션 환경은 미비한 상태로 로봇공학이나 3차원 시뮬레이션이 필요한 산업에 앞으로 더욱더 개발이 필요한 실점이다. 본 논문에서는 3차원 시뮬레이션을 하기 위한 방안으로 개발된 3D 모델빌더와 시뮬레이션 환경인 3DSIM(3D Simulation Environment)을 소개한다. 3DSIM은 현재 사용되고 있는 시뮬레이션 환경과는 다른 형식의 구조를 갖추고 있어 일반 시뮬레이션 환경과의 차이점에 대해 알아본다. 일반적인 시뮬레이션 환경은 서버와 클라이언트로 나뉘어 서버에서는 특정 모델에 대한 연산을 수행하기 위한 환경을 제공하며, 클라이언트에서는 서버에서 수행된 연산을 효율적으로 분석하기 쉽도록 보여주는 환경으로 나된다. 하지만, 3차원 시뮬레이션 환경인 3DSIM은 3차원 객체를 디자인하는 과정이 필요하며, 3차원 객체를 디자인하였을 경우, 각각의 파라미터를 통하여 시뮬레이션 되어야 한다는 점에서 일반적인 시뮬레이션 환경과의 구조가 다르게 된다. 3DSIM개발을 통하여 3차원 시뮬레이터 개발을 보다 편하게 개발할 수 있도록 하였으며, 시뮬레이션 모니터링 및 제어가 용이하도록 개발하였다.

In the medieval age of Europe when the noble people of various regions enjoyed unique cultures and life styles where made by coachbuilders. Such coaches would later affect the styles of the earlier automobiles equipped with the driving engine. Later, as the gasolines engines began to be distributed, the automobiles could afford to be flexible in terms of size and weight, while their performances and designs began to be enhanced rapidly. The important aspect of earlier automobile manufacturing was the phased development of styling which represented the pure approach to functions as well as the historical background. It can be known that such a development of automobile styling reflected the concerned industrial advancement and social influences of each region. At this juncture of time when the massmotorized modern society's demands for automobiles are unlimited and diversified, this study was aimed at reviewing the fundamental implications of automobile designs over time.

This paper proposed the method to find out the optimal sensing point of temperature in test-bed with the sensor of temperature, such as real residence. We selected optimal locations by checking temperature change which was simulated by the means of CFD (Computational Fluid Dynamics) and the variation of air flow. We made 3-dimensional model of the testbed using DesignBuilder software, and ran the CFD. We selected the optimum temperature measurement location of 1.5 m height from the floor and low temperature variation. The experiments were conducted 30 temperature and humidity sensors in real place. After that, we confirmed the results of temperature change.

The aim of this study was to analysis the Heating/cooling performance of movable insulation system built in apartments. The process of this study is as follows: 1) Test-cells of movable insulation are designed through the investigation of previous paper and work. The type of the movable insulation used in test-cell is low emissivity(5%) insulation, measured for heating season and the thermal effects are analyzed. 2) The simulation program(Design Builder) was used in energy performance analysis. the reference model of simulation was made up to analysis energy performance on movable insulation system. 3) Selected reference model(Floors:15, Area of Unit:115.5$m^2$) for heating/cooling energy analysis, Energy performance simulation with various variants, such as slate angle of movable insulation(5$^{\circ}$, 30$^{\circ}$, 50$^{\circ}$) and position of movable insulation. Consequently, When movable insulation system is equipped with balcony window of Apartment, Annual heating energy of reference model was cut down at the average of 5.4kWh/$m^2$ or 4.6% of heating/cooling energy.

Natural ventilation through openings such as windows in school buildings is an efficient resource for natural cooling during the intermediate season of the year. Because the natural ventilation uses the wind outside the building, the amount of ventilation will depend not only on the wind speed and wind direction but also on the window layout and open window ratio. Therefore, in this study, the natural ventilation plans of school classroom windows are divided into 4 types and 8 cases as shown in Table 1. The characteristics of cooling effect by natural ventilation are simulated by applying Energyplus's Airflow Network Model and the comfort of the occupants is evaluated by the number of hours included in the 80% acceptability range of the ASHRAE Standard 55-2010 adaptive comfort model for the weekdays (Monday-Friday) and the class hours (08: 00-19: 00). Based on the analysis results of the above, this study presents basic data related to classroom cooling plan using intermediate season natural ventilation.

Communication between system modules is applied using the Modbus protocol in industrial sites including smart factories, industrial drones, building energy management systems, PLCs, ships, trains, and airplanes. The existing Modbus was used for serial communication, but the recent Modbus protocol is used for TCP/IP communication.The Modbus protocol supports RTU, TCP and ASCII, and implements and uses protocols in embedded systems. However, the transmission I/O devices for RTU, TCP, and ASCII-based protocols may differ. For example, RTU and ASCII communications transmit on a serial-based communication protocol, but in some cases, Ethernet TCP/IP transmission is required. In particular, since the C language (object-oriented) is used in embedded systems, the complexity of source code related to I/O registers increases. In this study, we designed software that can logically separate I/O functions from embedded devices, and designed the execution logic of each instance requiring I/O processing through a delegate class instance with Modbus RTU, TCP, and ASCII protocol generation. We designed and experimented with software that can separate communication I/O processing and logical execution logic for each instance.
