In these days of world-wide business environment, the characteristics of quality management are variety, specialty, decentralization, totality, etc. Thus nowadays quality management is demanded to incorporate these new concepts. We propose a web-bused distributed expert system for this purpose. The system consists of four expert systems for design of experiment, acceptance inspection, statistical process control and reliability management corresponding to design quality, incoming-material quality, manufacturing quality and usability quality, respectively, throughout the total product life cycle. Each distributed expert system at the horizontal level in the hierarchy carries out its own quality jobs independently. At the lower level in the hierarchy there is an expert system for measurement analysis to provide reliable data, and at the upper level, an expert system for total quality management to coordinate, integrate and make final decisions. A prototype has been developed and its application is presented.

Research activities and discussions on specialized areas reflecting the specificity of landscape construction are necessary. Therefore, this study was conducted with the purpose of presenting basic data for efficient field management by deriving items necessary for safety management in landscape construction fields through experts' opinions. A survey was conducted using Delphi analysis to derive "management items" and "safety management items according to landscape type" for landscape construction field safety for a total of 15 landscape construction specialists. The survey results showed that four top items were derived from the "management items" for the safety of landscape construction fields; they include: "safety and health management organization and education," "industrial safety and health management expenses," "payment of personal protection," and "establishment of safety measures." In addition, two to five items for each higher item appeared and resulted in a total of 13 lower items. Personnel, organization, budget, etc. for safety management are always required in the field, and the monitoring part of whether these elements are working was also taken up as a management item. In the "Management items according to each landscape construction" a total of eight landscape type were distinguished, they include: 'Reinforced concrete work', 'Masonry work', 'Plaster's work', 'Waterproof work', 'Stone masonry work', 'Pavement work', 'Facilities work', and 'Planting work'. Furthermore, two to seven sub-items for each construction type were derived, and a total of 35 management items were presented.

In Korea, Total Maximum Daily Loads(TMDLs) has been enforced to restore and manage water quality in the watersheds. However, some assesment of implementation plan of TMDLs showed that the achievement of the target water quality is not related to the proper allocation loads because difference of flow duration interval. In the United States, the discharge loads are determined by water quality modeling considering standard flow conditions according to purpose. Therefore, this study tried to develop the allocation method considering economical efficiency using water quality model. For this purpose, several allocation methods being used in the management of TMDLs is investigated and develope an allocation criteria considering regional equality and uniformity. Since WARMF(Watershed Analysis Risk Management Framework) model can simulate the time varying behavior of a system and the various water quality variables, it was selected for a decision support system in this study. This model showed fairly good performance by adequately simulating observed discharge and water quality in Miho watershed. Furthermore, the scenario simulation results showed that the effect of annual average water quality improvement to remove 1kg BOD is more than 25 times, even if point pollutants treatment facility is six times more expensive to operate than non-point pollutants treatment facility.

In this paper, the systematic problems of safety management in domestic construction industry are presented by the investigation and analysis of construction fatal injuries. In particular, it is discussed that the current construction safety management system by contractors leading is ineffective to prevent the serious accidents caused by inappropriate planning and design and to circulate the safety management cycle without interruption. A couple of ways for improving domestic construction safety management system are suggested in broad perspective. This is done by the analysis of construction safety management system of four advanced industrial countries such as the United States, the United Kingdom, Germany, and Japan and the study of a best practice. Total safety management system by owners leading is recommended to prevent construction accident effectively because this system makes all the parties join to the management system and distribute the responsibilities clearly to each party. This will drop the accident occurrence rate by dragging all the parties' cooperations and activating the total safety management system in an early stage.

There are many Korea companies who are introducing many kinds of management renovation methods in order to attain more management achievement. So many personnels under CEO are frying to change themselves to fit those kinds of management renovation methods. Now, all kinds of books for supervisors have published, but it is not easy for those supervisors to understand those books as those books do not fit for their own companies situation. The best management methods in the best companies in U.S.A. actually can not be well introduced in Korea. So, the management methods should be changed with the environment's changing. Therefore, the company management is the process to suit the continue changing environment.

As the Korean economy went into a recession because of the global financial crisis in 2008, in order to vitalize the Korean economy, the government raised SOC budget and made its execution earlier. To prevent increases in budget for the government financial investment projects, the government controlled the project cost of SOC construction projects by enacting 'Guideline for total project cost management' in 1994 and complementing the relevant system. However, different from government intention, the total project cost of SOC projects were increased drastically. Hence, the government authorities and research institutions insisted the necessity of supplementation and improvement for the total project cost management system. This research is to provide the improvement for the total project cost management system of domestic SOC projects. In this research, As-Is Model was adjusted considering status of the total project cost management in the current SOC projects. Also the cost management of construction projects between domestic and other developed countries was studied, analyzed and compared. Based on the above, problems related to total project cost management of domestic SOC projects were found out and an improved total project cost management was provided to improve these problems.

The aim of this paper was to look at distribution intensity of casual wear brand before and after IMF Management System. It also provides the guide to distribution design and reinforces the strategy of the brand of it. Since the firm especially in casual wear industry recently has had difficulty in how to decide and to select the distribution numbers in the domestic market. Based on the data in‘98 Korea Fashion Guide’and ‘Korean Fashion Brand Annual’, 78 brands had been analyzed with percentage, multiple regression. The results were as follows: In general, the lower the price of the product is and the higher the total sale is, the more intensive the distribution of the casual wear brand is before and after IMF Management System. The longer the launching period is, the more intensive the distribution of the casual wear industry is after IMF Management System. Besides, there is difference between the brand origins in the distribution intensity. In addition, two brand types were classified and tested. The distribution intensity of jean casual wear and uni-sex casual wear have related to the price after IMF and the total sale before and after IMF Management System while there is no relationship with the launching period before and after IMF Management System. The distribution intensity of the domestic brand have related to the price, and the total sale, while the foreign brand has a relationship with the total sale before and after IMF Management System. The foreign brand has related only to launching period after IMF Management System.

In this study, it was proposed that a method of setting the target water quality for TOC using the watershed model and the load duration curves to manage non-biodegradable organics in the total water load management system. To simulate runoff and water quality of the watershed, the HSPF model is used which is appropriate for urban and rural areas. Additionally, the load duration curve is used to reflect the variable water quality correlated with various river flow rates in preparing the TMDL plans in the U.S. First, the model was constructed by inputting the loads calculated from the pollutant sources in 2015. After the calibration and verification process, the water quality by flow conditions was analyzed from the BOD and TOC simulation results. When the BOD achieved the target water quality by inputting the target year loads for 2020, the median and average values of TOC were proposed for the target water quality. The provisional method of TOC target water quality for the management of non-biodegradable organics, which is one of the challenges of the total water load management system, was considered. In the future, it is expected to be used as basic data for the conversion of BOD into TOC in the total water load management system.
