Many construction companies are simultaneously carrying out numerous projects in the housing construction industry. It is essential to accurately forecast the cash flow of a project through optimal process management and resource input in order to manage funds rationally and enhance the competitiveness of a company. Current cash flow forecasting methods offer lower accuracy due to a large gap between the revenue and expenditure element. Expenditure elements depends on the real-time changing actual cost for work performed. This research survey was conducted on the actual state of construction management of K company to investigate the problems of cash flow forecasting. To achieve this, the work process and construction management system were integrated to improve the cost management system of K company. To accurately forecast the cash flow of a project, revenue and expenditure elements were displayed in the total cash flow forecast window. This research is expected to assist in the implementation of a system of cash flow forecasting on housing construction by excluding negative elements of revenue and expenditure.

13억의 인구와 370만 평방마일의 영토를 가진 중국은 공산주의 경제체제에서 자본주의 경제체제를 도입하여 시장개방, 자유경쟁 경제방식으로 전환함에 따라서 급격한 경제성장을 이루어 국제통화기금(IMF)의 1993년 보고에 의하여 국내총생산액(GDP)가 1조 6천억$로 미국, 일본에 이어 세계 3위의 경제 성장을 이루어 경제강대국으로 부상하고 있고 아울러, 무한히 넓은 땅덩어리와 천연 및 인적자원을 기초로 한 앞으로의 성장잠재력이 크게 기대되어 미국, 일본을 비롯한 선진국이 중국에 대한 투자를 다방면으로 검토하기 시작했고 생명공학분야도 예외없이, 연구분야에는 포장시험, 임상시험 등 실용화 연구에 중국측 강점을 이용한 협동연구, 중국정부 자체가 상업화 가능성이 높다고 판단하는 Torch High Technology Development Center에의 외국기업이나 연구소의 참여 등으로 확대되고 있다. 산업계는 벤쳐 케피탈의 활성화를 통한 첨단기술에 대한 투자를 적극적으로 실시하는 한편, 제약 및 생명공학분야의 합작투자를 통해서 외국의 기술, 장비, 자본 및 노하우를 도입하고 있다. 우리나라는 여러 산업 분야에서 대중국 투자 또는 협력이 활발히 이루어지고 있지만, 생명공학 분야는 그렇지 못한 것 같다. 연구개발의 국제경쟁력은 우리나라의 자체 연구개발도 중요하지만, 아울러, 외국에 대한 연구 동향을 파악함과 가능한 분야에 대한 투자와 협력을 통한 공동관심과제의 도출은 중요한 의미를 갖는다. 이러한 배경에서 중국의 Biotechnology분야에 대해서 서로의 이해증진과 공동연구 분야의 도출가능성을 타진하기 위해서 한국미생물학회 한국산업미생물학회가 중국의 Chinese Society for Microbiology의 공동 주최로 중국 상해에서 금년 4월 2일에서 4월 3일까지 2일동안 제 1회 한.중 생명공학 심포지움이 개최되었다. 필자는 심포지움에 발표자로 참석하였다가 심포지움 후, 방문했던 연구소인 Shanghai Research Center of Biotechnology, Shanghai Institute of Industrial Microbiology 및 Scientific Research Institute of Food and Fermentation Industry을 소개하고저 한다. 짧은 기간의 방문이라 주로 해당연구소의 자체소개 자료를 중심으로 방문하면서 느낀점을 기술하고저 한다.

As the recent construction projects have been carried out as a mixed-use complex project that includes architecture, civil, mechanical, electrical, and landscape, as well as become bigger and high-rise with the increased repetitive works, the TACT technique has received more attention as an effective method for achieving a target completion date by securing the continuous works. Although the TACT technique can maintain a steady flow without the interruption of works in order to utilize the resources of the repetitive works, it can not be considered as the systematic scheduling technique because the schedule computations are not possible as well as a critical path can not be recognized. This paper proposes the applicabilities of scheduling and monitoring the TACT schedule by the BDM technique as comparing and analyzing the methodologies for apartment finish works by the Excel, the Primavera(P6) based on the PDM technique, and the Beeliner based on the BDM technique that is a new networking technique, respectively.

This study aimed to suggest the tasks which public support groups should fundamentally perceive and develop support models based on it so that socioeconomic activities, which have been spreading in recent years, can settle in local communities. For this aim, this study was proceeded based on Gyeonggi Province, which has established socioeconomic support center at metropolitan councils and local government councils. The demands by Gyeonggi Province residents toward the policies by Ddabok communities and local community invigoration measures have been examined through demand survey. In the analysis, characteristics and support tasks of the demands have been identified based on the survey results and six support models have been developed according to the tasks. The derived tasks are overcoming low understanding of Ddabok communities, low participation in community activities, and poor will to perform socioeconomic practices and satisfying the demand toward community activity areas adjacent to residence. Furthermore, the differences with the residents who have an experience of taking part in the Ddabok Community Project have to be overcome. Based on these study findings, this study suggested that support models of integration style and differentiated style, response to demand style and customization to capability style, and resources-focused style and resources-scattered style are necessary in order for socioeconomic communities like Ddabok communities to settle in local communities.

Recently frequencies and scales in natural disasters have been significantly increased and enlarged and that leads to increase interests on preventing disasters. As natural disasters occur, it is difficult to fulfill the scale of natural disasters using ordinary stocks in a local government. Thus, it is necessary to establish a system that commonly uses protection resources according to regional characteristics in order to rapidly implement labor mobilization and equipment distribution based on the damage of natural disasters. In this study, regional characteristics in Korea provinces are analyzed and 'a way of composing a local government consortium for common disaster responses' is proposed. First, a disaster map that represents the amount of damage for each local government published in the disaster yearbook from 2002 to 2011 is produced using GIS. Then, the whole land is divided into five different sections according to administrative regions and that are divided into 12 clusters again based on the geographical and humanistic characteristics and the analysis of the scale of damage in typhoons and heavy rainfalls. Finally, disaster protection base stations for each region are selected. The data of analyzing disaster damages may be used as a reference material for establishing disaster prevention plans.

Binary trans-activation (pOp/LhG4) system is one of the regulatory systems of transgene expression. The target gene expression is achieved by crossing the reporter plants with an activator in this system. In this study, we used the features of this system in Chinese cabbage as a way to protect genetic resources and new varieties. To establish pOp/LhG4 system in Chinese cabbage, we designed an activator (35SLhG41300), and reporter constructs (pOpGUSBart) and co-transformed using Agrobacterium. The transgenic plants were selected by antibiotics and the functional activity of pOp/LhG4 system was confirmed by GUS expression. To induce the tissue-specific function, we constructed pOp/LhG4 system (795LhGBart) using female tissue specific promoter (ProAt1g26795) of Arabidopsis. Co-transformed transgenic plants clearly showed tissue specific expression in Arabidopsis. The results suggest the possibility of the system's application of $F_1$ generation can be restricted by expressing the target gene to protect a new variety and genetic resource in Chinese cabbages.
