In this paper, we proposed a Proactive Application Service Engine (PASE) supporting tailor-made distributed application services based on the Distributed Object Group Framework (DOGF) efficiently managing distributed objects, in the viewpoint of distributed application, composed application on network. The PASE consists of 3 layers which are the physical layer, the middleware layer, and the application layer. With the supporting services of the PASE, the grouping service manages the data gathered from H/W devices and the object's properties for application by user's request as a group. And the security service manages the access of gathered data and the object according to user's right. The data filtering service executes the filtering function to provide application with gathered data. The statistics service analysis past data. The diagnostic service diagnoses a present condition by using the gathered data. And the prediction service predicts a future's status based on the statistics service and the diagnostic service. For verifying the executability of the PASE's services, we applied to a greenhouse automatic control application in ubiquitous agriculture field.

지난 4월 13일 블룸버그 통신에 의하면 올해는 폭염 등으로 최악의 기상이변 가능성이 높다고 예측하고 있다. 또한 NASA의 고다드 우주연구소는 온실 효과와 엘니뇨 현상이 상호작용을 일으켜 가장 더운 해가 될 것임을 밝힌 바 있다. 이에 따라 폭염이 건강에 미치는 영향 및 폭염 대비 요령 등에 대하여 알아보자.

온실기체농도에 대한 감시는 전세계적으로 미국의 NOAA(National Oceanic and Atmospheric Administration)/CMDL(Climate Monitoring and Diagnostic Laboratories)의 관측망을 비롯하여 세계기상기구(WMO)의 지구대기감시(GAW)계획에 의하여 수행되고 있다(Keeling et al., 1976 ; Komhyr et al., 1989). 기상청에서는 온실기체의 관측을 위하여 1994년에 전남 무안의 무안기상대에 비분산적외선 이와 같이 측정된 $CO_2$농도자료가 배경대기관측자료로써의 신뢰를 받기 위해서는 적절한 질관리를 통하여 인간 및 생물의 활동에 의한 직접적인 영향 제거하여야 한다.(중략)

온실은 동절기 난방을 주목적으로 설비되어 년중 작물재배 시는 하절기 온실내부 온도가 필요이상으로 상승하여 실내온도가 35-4$0^{\circ}C$ 정도로 올라가는데 이러한 상태에서의 온도는 많은 작물의 생육적온을 벗어난 온도로서 고온장해를 나타낸다. 이 같은 문제점을 해결하기 위해 몇 가지 냉방방법이 알려져 있는데 에어컨 등과 같은 냉방장치를 이용한 기계적 냉각방식과 수분증발을 통한 증발식 냉각방식으로 대별되며 이중 기계적인 냉방방식은 설비나 유지관리 면에서 비용이 많이 들어 비경제적이고, 증발냉각 방식중에서도 Fan and Pad 법이 가장 효과가 좋은 것으로 알려져 있으나 이역시 설치 및 유지비가 많이 들고, vep의 탈부착이 어려워 고정시켜놓을 경우 동계 광투과에 방해가 되는 등의 문제가 많다.

Today, more than thiry countries around the world are designated as a mandatory GHG(GreenHouse Gas) emissions country from the UNFCCC(United Nations Framework Convention on Climate Change). Korea is also possible to designate a mandatory GHG emissions country after Second mandatory emissions which will be started in 2013. Accordingly, Korea government has made efforts to reduce GHG and has enforced energy-related policies to deduce building energy. But there is no process such as providing of existing building improvement recommendations or expert verification for building remodeling in Korea energy-related policies compared with policies in other countries. For this reason, improvements of Korea which divided governments and city provinces are suggested. However suggested improvements are directions, so additional research is needed for detail methods.

An experiment for an optimized automatic greenhouse environment in a flower farming greenhouse by building a ubiquitous sensor network with various sensors was conducted and the results were evaluated. And various culturing environmental information and data in the greenhouse were collected and analyzed. Then, the greenhouse was designed to maintain the best culturing environment on the basis of existing recommended optimized figures. By measuring the growth of the crops in the greenhouse, A system which controls facilities in the greenhouse to maintain the best culturing environment in accordance with change in the environment was analyzed.Computer simulation result proced that we discovered that controlling the facilities and the artificial light source increased production, enhanced quality, reduced labor and heating cost immensely. The experiment has proved that the u-flower farming system can maximize the income of farm families by sending warning messages to users of this system when weather suddenly changes so that users may cope with such changes and maintain the best culturing environment.

The potential mitigation of greenhouse gas (GHG) is studied in the Pohang steel industrial complex (PHSIC). The total GHG emission in 2010 is estimated to be in the range from 4,174,000 to 4,574,000 $tCO_2-eq$ in PHSIC. To meet the target proposed by the government, it is needed to reduce 552,000 $tCO_2-eq$ at minium by 2020. To estimate the potential amount of GHG reduction, the technologies used in the voluntary carbon reduction projects are applied to 51 companies which are subject to GHG target management. From the viewpoint of technological availability and payback period, the fuel conversion and waste heat recovery have an advantage in the short term with a possibility to reduce 160,000 $tCO_2-eq$. In the mid term, the thermal technologies in steel and iron industry have the potential to cut 229,000 $tCO_2-eq$, while the electrical technologies have the potential of 125,000 $tCO_2-eq$ reduction. The gap between the target GHG mitigation and potential reduction using the short and mid term technologies is about 38,000 $tCO_2-eq$, which should be compensated by the fundamental process innovation and the implementation of the most cutting-edge technologies including renewable energy.

As the seriousness of the global environment pollution is gaining our attention recently, researches on application of greenhouse gas emission of ship are being carried globally. However domestic study on greenhouse gas emission from ship was not carried out in various fields. In this study, quantitative data which was presented by greenhouse gas emission of training ship HANBADA and greenhouse gas emission was calculated by Tier 1 method based on total fuel consumption and amount of shore power. Actual voyage data for 1year in 2012 was used to analysis the greenhouse gas emission. This study showed how many weight of gases were exhausted per 1 gross tonnage and per 1trainee in the training ship. There is a need of further research to reduce pollutant and to respond to international environment regulation consistently.
