In this paper, we described the integrated monitoring system for low-voltage panel boards. This system consists of three parts, a panel board controller, an integrated monitoring unit and a remote PC. The panel board controller which was made of CT/PT unit, control unit and power supply is able to transmit variable parameter for monitoring and diagnosis of low voltage branch circuits. Also, the integrated monitoring unit was collected monitoring data from panel boards and displayed on the touch panel.

The purpose of this study is to suggest the concept of an integrated unit and to develop integrated units considering the layout of luminaires and diffusers in workspace. An integrated unit can be defined as a planning unit which satisfies the environment comfort criteria of workspace. Integrating process of each unit was proposed by considering the current workspace planning process. Luminaire and diffuser types are classified by surveying the workspace of the domestic and foreign office buildings. Several lighting units and air-conditioning units were developed by visual and thermal simulation, and integrated units for various architectural module which satisfies the visual and thermal comfort criteria were drawn from those units.

The need for urban-scale energy simulation is increasing as the world is aware of urgency to decrease $CO_2$ emission. As a bridge of building energy simulation and that of urban, this paper presents a case study to examine the effect of changing resolution of a model in case of complex apartment unit. Also it suggests a modeling strategy to correct differences caused by simplification of the model and evaluate the extent of its use.

The purpose of this study is to develop the air-conditioning unit combined with the lighting unit for workspace and to supply its performance data at architectural design stage. The air-conditioning unit is one of the components of a workspace integrated unit, which can be defined as the planning unit satisfying the environmental comfort criteria of workspace. Air-conditioning diffusers are classified according to throws and features by literature review and case study. Then diffusers are combined with the lighting unit. Through the CFD simulation, the thermal performance of each unit was evaluated and finally various air-conditioning units combined with the lighting units were developed.

This study investigates the effect of a combination of homeopathic medicine and electro- acupuncture in two patients with breast cancer and severe liver disease who could not receive standard anaesthesia therapy due to liver problems. Specifically, measurable and quantifiable parameters were used to evaluate whether an integrated approach-consisting of electro- acupuncture and a homeopathic medicine diluted above Avogadro's limit (that is, above a potency of 12CH) during the pre-surgical, surgical and post-surgical phases -can improve general well-being of a patient undergoing breast cancer surgery. In breast cancer surgery, we employed an integrated approach consisting of induction with hypnotics and muscle relaxants, followed by maintenance with anaesthetic gas, combined with a homeopathic treatment (Arnica montana 15CH and Apis mellifica 15CH) before and after surgery and an electro- acupuncture treatment performed in the pre- and post-surgical phases without any analgesic/pain relieving medications. Both of the patients treated with the integrated approach improved their overall condition without need for other common pain relieving medicines. Additionally, thanks to their rapid awakening, the patients were not relocated to a protected area and the hospitalization was shorter. A multidisciplinary approach incorporating homeopathic medicine and electro-acupuncture can be a solution for patients who need or ask about a different and/or safer alternative to the standard treatment. This approach can offer a safe, much less expensive, non-invasive and viable alternative for such cases. Moreover it can be useful for an opioids free anesthesia.

USM(Unit Service Management System) is the development tool and methodology to handling the event process in a U-City integrated platform by using the minimum unit services. USM can be one of the SOA development methodology. Minimum unit service has a minimum business logic that can be executed with input and output parameters. Minimum unit service consists of three parts : service profile, service input and output parameters and service execution information. USM provides two types of the execution method. One is module execution and the other is web service execution. The development of the event sinario by the USM development methodology can reduce the cost and duration of the u-service development by raising the rate of reusing minimum unit service.

Series hybrid electric vehicles (SHEVs) having multiple power sources such as an engine- generator (EnGen), a battery, and an ultra-capacitor require a power control unit with high power density and reliable control operation. However, manufacturing using separate individual power converters has the disadvantage of low power density and requires a large number of power and signal cable wires. It is also difficult to implement the optimal power distribution and fault management algorithm because of the communication delay between the units. In order to address these concerns, this approach presents a design methodology and a power control algorithm of an integrated power converter for the SHEVs powered by multiple power sources. In this work, the design methodology of the integrated power control unit (IPCU) is firstly elaborately described, and then efficient and reliable power distribution algorithms are proposed. The design works are verified with product-level and vehicle-level performance experiments on a 10-ton SHEV.

The integrated protection unit of CHEONGUNG is composed of chemical-biological equipment and air conditioner equiped heating element. The protection capabilities against chemical-biological agent were measured by using simulant agents such as n-Hexane, KM5 Screening Smokes and CS agent. The experimental test results with simulant agents verify the protective performance of the integrated protection unit.

Double facade systems are often paid attention of as an effective energy saving measure for curtain wall buildings. However, it is not easy to install the system in existing buildings and requires substantial investment. An innovative double window system is proposed in this study which can be installed with exiting window systems in a cost effective way. the proposed system is connected to existing return ducts to make airflow between the existing window and the newly installed window. To ensure the best performance of the proposed system, simulation-based analysis was implemented in which airflow characteristics of inside double window were examined according to air pressures of return duct and window material by using computer simulation ESP-r. the overview of the proposed system and the results of the simulation-based analysis are presented in this paper.

이 연구는 2009 개정 교육과정 5~6학년 과학 교과서에 새롭게 제시된 통합탐구 단원에 대한 초등학교 교사들의 인식과 지도 실태를 조사하여 통합탐구 단원 구성과 지도의 개선 방안을 모색하고자 하였다. 이를 위해 탐구지도와 관련된 기존 설문지를 수정, 보완하여 통합탐구 단원을 지도한 경험이 있는 교사들에게 설문을 실시해서 응답 내용을 분석하였다. 그 결과, 교사들은 통합탐구과정 지도의 중요성에 대해 긍정적으로 인식하고 있었다. '통합탐구능력 습득 및 발달, 과학 학습의 전이, 자유탐구 실행' 측면에서 교사들의 통합탐구 단원의 적용 효과에 대한 인식은 긍정적이었으며 그 이유로 '통합탐구과정 학습을 위한 별도의 시간 확보, 후속 학습에서의 활용, 자유탐구 활동에서 통합탐구과정 적용의 용이함'을 들었다. 반면에 교사들은 '통합탐구과정의 분절적 학습, 통합탐구 단원과 다른 단원 간의 연계성 부족, 학생의 호기심 유발이 어려운 교과서 내용 구성'을 이유로 통합탐구 단원의 효과에 대해 부정적인 의견을 제시하기도 했다. 또한 통합탐구 단원의 지도 실태에 대한 조사를 통해 많은 교사들이 통합탐구과정 지도 시 교과서 내용을 그대로 따르는 것을 확인하였다. 교사들이 통합탐구 단원 지도 시 어려움을 가장 크게 겪는 과정은 문제인식이었으며 그 다음으로 가설설정, 변인통제, 자료변환 및 자료해석, 일반화, 결론도출 순이었다. 교사들이 어려움을 겪는 이유는 '학생들의 호기심 경험 이해력 부족, 교사의 전문성 부족, 교과서 구성의 한계 및 학습 시간 부족' 등으로 나타났다. 이러한 연구 결과는 통합탐구 단원의 개선 및 통합탐구과정 지도 관련 교사 전문성 제고를 위한 노력이 필요함을 시사한다.
