군락분류학에 기초한 현존식생도를 이용하여 토지에 대한 생태적 안전성 또는 위약성을 평가하는 '잠재인간간섭도' 평가기법을 개발하였다. 4개 범주(삼림지역, 개방수역-호소와 하천, 경작지 면적, 주택-도시화의 인공 면적)에 따라 입지도에 대한 직접평가 및 간접평가로부터 격자법과 등고선법에 의한 '잠재인간간섭도(潛在人間干涉圖)를 제작하였다. 이것을 토대로 토지의 훼손 잠재성을 평가하는 '교란핵구역'과 '위약(危弱)세포구역'을 규정하고, 토지 관리를 위한 생태적 접근을 시도하였다. 사례연구로 973개의 격자(500 m×500 m)로 이루어진 부산광역시 기장군 일대의 현존식생도 상에서 이루어졌다. 사례연구 지역 내에서 '교란핵구역'은 51군데이며 '위약세포구역'은 28군데로써 대상 면적의 약 8.1%를 차지하는 것으로 나타났다. 식생학적 현존식 생도를 이용한 '교란핵구역'과 '위약세포구역'을 발굴하는 잠재인간간섭도는 토지 이용과 보존에 관한 생태학적 전략 구축에 있어서 구체적인 현장적 입지진단 정보를 제공하는 유효수단인 것으로 밝혀졌다.

To increase the productivity and efficiency of an enterprise, all relevant product information should be provided to shop floor workers timely and in a unified form because shop floor workers are final consumers of most accumulated information generated from various departments of an enterprise. But, most existing enterprise information systems have an emphasis upon providing design/manufacturing information to office workers. Proposed in this study is the development of integrated design/manufacturing information system focused on providing cohesive information required to shop floor activities. For developing integrated information system, the functional requirements at the shop floor are identified and analyzed. Based on the extracted functional requirements, object-oriented system design and implementation is conducted. By using this system, shop floor workers can use all relevant information required to their daily operation in a integrated and unified form.

오염지하수에 대한 복원시 필요한 주입관정, 지하수 인공함양을 위한 주입정 및 지열펌프에 사용되는 지하수 관정 등 지하수 관정을 이용하는 다양한 활동이 향후 국내에서 활발해질 것으로 사료된다. 그러나 이에 관한 법적 규정이 충분치 않아 일반 국민이나 담당 공무원에게 실무적으로 혼란이 있을 수 있다. 이에 미국 미주리주의 관련 규정 몇 가지를 간단히 소개함으로써 이에 관한 규정이 전문가들의 논의를 거쳐 국내에서도 속히 마련되기를 바란다.

With the rapid growth of the World Wide Web and electronic information services, information is becoming available on-Line at an incredible rate. One result is the oft-decried information overload. No one has time to read everything, yet we often have to make critical decisions based on what we are able to assimilate. The technology of automatic text summarization is becoming indispensable for dealing with this problem. Text summarization is the process of distilling the most important information from a source to produce an abridged version for a particular user or task. Information retrieval(IR) is the task of searching a set of documents for some query-relevant documents. On the other hand, text summarization is considered to be the task of searching a document, a set of sentences, for some topic-relevant sentences. In this paper, we show that document information, that is more reliable and suitable for query, using document length normalization of which is gained through information retrieval . Experimental results of this system in newspaper articles show that document length normalization method superior to other methods use query itself.

Due to the increasing complexity to handle conflicts and interruptions caused by resource failures and rush orders, shop control is obliged to redesign its organization according to the changing demands of the manufacturing control. These demands are leading to the development of decentralization and gradually to their permanent optimization. As a result, a powerful modeling method which can be adapted efficiently is required. The use of agent theory enables specific modeling of the relevant shop planning activities. The planning activities are modeled in a so-called activity modeling through the definition of three classes of agents; Plan Agent, Manufacturing System Agent and Control Agent as well as the description of the cooperative relationship among these agents. On the basis of the activity model the agent-based shop control method is developed which emphasizes the distributed problem-solving and the cooperation with relevant agents.

We consider counterparty risk in CDS rates. To do so, we use a multivariate jump diffusion process for obligors' default intensity, where jumps (i.e. magnitude of contribution of primary events to default intensities) occur simultaneously and their sizes are dependent. For these simultaneous jumps and their sizes, a homogeneous Poisson process. We apply copula-dependent default intensities of multivariate Cox process to derive the joint Laplace transform that provides us with joint survival/default probability and other relevant joint probabilities. For that purpose, the piecewise deterministic Markov process (PDMP) theory developed in [7] and the martingale methodology in [6] are used. We compute survival/default probability using three copulas, which are Farlie-Gumbel-Morgenstern (FGM), Gaussian and Student-t copulas, with exponential marginal distributions. We then apply the results to calculate CDS rates assuming deterministic rate of interest and recovery rate. We also conduct sensitivity analysis for the CDS rates by changing the relevant parameters and provide their figures.

It is important to improve the energy performance in the industrial sector, and therefore most of the manufacturing companies need the energy performance indicators to identify the target and to verify the energy savings. However, the conventional energy performance indicators such as the total energy consumption and the energy intensity are not proper to use. The reason is that they do not consider adequate relevant variables including productions in the boundary of the manufacturing companies. Therefore, the study provides the advanced energy performance indicator using by the linear regression model according to each energy source to manage the target and to verify the energy performance properly.

This study is to survey facilities installed at urban parks and identify park facilities desired by users through a questionnaire survey of users who actually use the parks. Then, the outcome will be compared and evaluated to install urban park facilities that reflect the desires of users in the future. Findings showed that park facilities currently installed are mostly those easy to install and manage among facilities suggested in relevant laws. Regardless of park types and sizes, similar facilities were installed across parks. A questionnaire survey of users showed that they wanted facilities to rest, sports facilities, waterscape facilities and facilities to accompany families. The result also showed that they wanted green area-style parks that have a lot of trees. Therefore, going forward, facilities reflecting such desires of users should be installed at parks as much as possible. When developing a park creation plan for each city, it would be critical to survey the opinions of residents in relevant areas in advance and reflect it to the creation plan.

In Malaysia, data on components suitability the established smoking cessation module is limited. This exploratory study aimed to evaluate the suitability of the components developed in the module for group behavioural therapy in workplace smoking cessation programs. Twenty staff were identified but only eight individuals were selected according to the study criteria during the recruitment period in May 2014. Focus group discussion was conducted to identify themes relevant to the behavioural issues among smokers. Thematic analysis yielded seven major themes which were reasons for regular smoking, reasons for quitting, comprehending smoking characteristics, quit attempt experiences, support and encouragement, learning new skills and behaviour, and preparing for lapse/relapse or difficult situations. As a result, the developed module was found to be relevant and suitable for use based on these themes.

Common system deployment is one of the global information systems strategies of a multinational corporation for large-scale development that can provide economies of scale and optimal use of scarce technical expertise. But while the same (headquarter) team implements the same system, the resulting efficiencies of those projects differ widely among the subsidiaries. This paper focuses on the differences between the efficiencies of these implementation projects. Eight prepropositions about the factors causing the differences have been developed from the previous research. These prepropositions are explored through a case study on the twelve overseas subsidiaries of a multinational electronic corporation headquartered in Korea. We found that three factors(autonomy of subsidiary, complexity of task, experience level of users) have strong relevant relationships and two factors(level of subsidiary country, level of process formality) have partial relevant relationships with the implementation outcome.
