Agriculture reservoirs need a systematic approach that can control water purity and water improvement. The area under study, Bunam Lake exceeds the agricultural water standard level due to contamination from the upper stream. When the Taean Enterprise City was planned, the water quality improvement plan was applied to minimize the environmental change. However, in order to continuously maintain the water quality in the Bunam Lake, it was essential to apply the Total Pollution Load Management System (TPLMs). In order to achieve the targeted water quality in the Bunam Lake, standard flow rates and targeted water quality levels were applied to obtain the loading capacity which is as follows : BOD 1,891.2 kg/d, T-N 1,945.7 kg/d, T-P 131.7 kg/d. Also, the regional development load was calculated as, BOD 1,083.6 kg/d, T-N 942.2 kg/d, T-P 61.8 kg/d, which is required to be deceased :- by BOD 378.4 kg/d, T-N 198.9 kg/d, T-P 31.6 kg/d in order to safely achieve the targeted water quality in the Bunam Lake.

GDS(Grating automatic Drawing System), which is an automatic design system of metal products called grating, is a system that produces various detailed drawings on the basis of information within a Plan Drawing that represents layout of the gratings such as locations, shapes, directions, etc. However, automatically produced drawings by GDS do not fully satisfy the standard of the general dimension marking method used among the layout designers. The lack of this standard quality mainly results from the fact that overlapping among dimension markings appears frequently. To solve the overlapping problem we applied the rule-based expert system which uses the expert's knowledges and facts to solve the problems. The rules for the expert system are designed based on the expertise of skilled layout designers within the grating production lines.

The recently built rural Hanoks have shown changes in appearances regarding its shape, space and size in the traditional floor plan. This is probably the transformation process to suit the needs of modern residence as new spaces and other factors are considered these days. The purpose of the research is to provide basic data for the innovation and construction of future Hankoks by analyzing the size features of the Hanoks in the rural areas of Jeeollanam-do and changing trends. They were divided into 5 types depending on the shape and the spacing of the living room and kitchen. Then size features per each type were analyzed. From this, it was revealed that there needs to be reasonable development of types in the standard design of Hanok because the size of the rooms is actually bigger than the standard design of Hanok in Jeollanam-do. The composition of the utility rooms should be classified as either domestic space or agricultural workspace considering that this area is rural but there are not enough storage spaces for agricultural machines and materials in most houses as they did not install external storage spaces. Therefore, it was analyzed that the size varies with the changes in the composition of space because of Hankok's similarities in the area of the rooms with typical apartments.

In the past annual recycling obligation rate calculation of Extended Producer Responsibility (EPR) system, it was difficult to operate the system efficiently, because responsible producers passively participated in the scheme only bent on achieving annual obligation without long-term plan. Thus, a new scheme of long-term recycling obligation rate began to be established every five year from 2008 in order to give the basis for the notice of annual specific operation standard and recycling obligation, thereby helping responsible producers to make a preparation with a plan and giving expectation of active operation of the scheme. However, in the operation of long-term recycling target program, while the development of prediction models and the evaluation for existing items has been conducted in various ways, applications for a new target items and the evaluation are quite insufficient. Therefore, in this study, problems in implementing long-term recycling goal of new target items will be examined, and more objective and rational long-term recycling rate calculation and the operation standard will be proposed. Thus, the long-term recycling target will play a role as a pacemaker to steadily improve the recycling performance of target items, and responsible producers will be expected to increase the achievement with the realistic capacity.

In South Korea, minimum reserve rate, which is to satisfy reliability standard, has been determined by simulation result using WASP. But, it is still controversial whether the level of minimum reserve rate is adequate. Thus, in this study, various analyses of minimum reserve rate are being conducted. WASP uses the probabilistic simulation technique to evaluate whether reliability standard is satisfied. In this process, forced outage rate and maintenance periods of each generator play important roles. Especially, the long-term plan can be varied depending on how maintenance periods deal with. In order to model maintenance periods in the probabilistic simulation technique, WASP uses derating method. However, broad analyses have to be conducted because there are various ways including derating method to model maintenance periods which result in different results. Therefore, in this paper, 3 different maintenance outage rate modeling methods are applied to arbitrarily modeled system based on the basic plan for long-term electricity supply and demand of South Korea. Results show impact of each modeling method on minimum reserve rate.

Purpose: The aims of this study were to analyze the frequency of standard nursing statements used in the Electronic Nursing Record (ENR) and to evaluate the degree of satisfaction by users of the ENR system. Methods: We retrospectively reviewed the ENR of 1914 patients who were admitted to our center between 1 May 2011 and 31 May 2011. Additionally, we collected questionnaires from 100 doctors and 300 nurses to evaluate the satisfaction of the users. Results: The frequency of use for the following standard nursing statements was investigated: standard nursing assessment statements (43.6%), standard nursing diagnosis statements (61.8%), standard nursing plan statements (46.7%), standard nursing intervention statements (56.9%), and standard nursing evaluation statements (41.7%). The mean satisfaction score was 3.03 out of 5 in the nurse's group, and 3.11 in the doctor's group. The nurses said the advantages of the ENR system were as follows: easy to access, informative, and standardized terms. However 75.7% of the nurse answered that they cannot express actual nursing situations exactly with the currently limited standard nursing statements. Conclusion: Development of various standard nursing statements is needed to meet the demands of the users. As a result, the use of the ENR system would become easier and more efficient for its users.

When operating Express and Standard trains, which run with two different scheduled time, in a single line with limited number of side tracks for overtaking standard trains, it is required to have various modeling methodologies and simulations in order to calculate an optimum headway to maximize the capacity of the line with the best scheduled time. Especially it is inevitable that following trains have to slow down or stop in the middle of their operations due to the preceding trains, in case it is inappropriate controlled about either in which station an overtaking should be taken or how long it should be. This study is to analyze TPS data which have been produced with a simulation program which the team has invented to optimize Express and Standard mixed traffic plan and to introduce an algorism which shows detected conflict data, calculates appropriate dwell time after getting overtaken and helps to decide stations for overtaking.

Human immunodeficiency virus is a retrovirus that causes acquired immunodeficiency syndrome. Acquired immunodeficiency syndrome is defined in terms of "either the occurrence of specific diseases in association with a HIV infection or a CD4 cell count below 200cells/ul" by centers for disease control and prevention(CDC). When performing the surgery of human immunodeficiency virus infected patients, several factors should be considered. First, standard precautions should be performed to prevent infection. It is safe to treat human immunodeficiency virus infected patients if we follow the standard precautions. Second, when making a surgical plan, surgeons have to take account of delayed bone healing and postsurgical infection. This case report presents a case of orthognathic surgery of human immunodeficiency virus infected patient.
