Currently, the domestic electricity rates for houses are charged by applying a progressive level according to monthly electricity usage. Electricity rates rise sharply wWhen the amount of electricity used is large, electricity rates rise sharply. The standardized electricity rate progressive system has limitations in that it lacks consideration of the consumers' power usage patterns and limits consumers' their options. Accordingly, the Ministry of Trade, Industry and Energy and the Korea Electric Power Corporation have been demonstrating the basis of a rate system for housing, which is a method of charging electricity according to the amount of electricity used by season and time. In this paper, 10 electricity usage patterns were derived through from AMI data analysis for 5 five years of 362 apartment complexes located in metropolitan cities. The patterns were, and then applied to the existing domestic electricity rate and time-by-time rates applied to demonstrations, and by time-by-time rates in the US and Australia. The effect of the optional rate by pattern was compared and analyzed. As a result, it was confirmed that benefits occurred in five5 patterns compared to existing rate plans, and the electricity rates increased in 5 five patterns, and t. This phenomenon shows the same phenomenon withis the same as the overseas rates, including domestic rates being demonstrated.

The purpose of using CBD in the object-oriented modeling is to improve the software capability by reducing iterative time and space complexity. Despites many achievements of CBD, it is needed to study about design patterns and it's standardization for the increment of CBD design reusability. However, it is rather possible that impetuous constructing meta-pattern languages and pattern repositories make adapting patterns to software development more complicate and difficult. By applying GoF design patterns to the design of the TMDL(Total Maximum Daily Load) environmental software discipline, this study suggests a method which specifies Pattern names at class names for retrieving, exploring the adapted patterns on the stage of software design without meta-pattern language which is a redundant abstraction, nor additional pattern repositories. Thus, this study can contribute on the reducing iterations and repetitions that are frequently occurred in the process of the environmental software developments.

In 2002, the 5-day workweek policy was effective in Korea. As we have expected, the 5-day workweek policy has changed people's travel behavior during weekdays and weekends. Several studies have been done to understand these changes and impacts on transportation systems. However, these studies have only focused on travel pattern changes without considering spatial factors. Said in another way, although individual travel pattern changes are usually investigated, indices adopted cannot describe travel pattern changes in a proper way due to lack of the spatial distribution measure. This study aims to analyze travel change since the 5-day work week policy in effect using a new index (i.e. Travel Vector Index) developed in this study, which can explain travel pattern changes in terms of magnitude and spatial point of views. The new index uses a GIS technology and TCS (Toll Collection System) databases in Korea. The results in this study show that the index is very useful and reliable to measure the travel patterns changes. They are applied to TCS data set and the results show that the 5-day workweek policy significantly affects on travel behaviors.

In order to develop a bodice prototype suitable for obese women in their 20s, this study compared and analyzed a total of five pattern system methods, including prototype of France and Japan, one prototype for education in Korea and two prototype for industries in Korea. Through this, this study attempted to investigate the bodice pattern system suitable for the development of plus-size women's clothing. For the pattern drafting, pattern 1 was applied with the most body dimensions such as interscye fold front, interscye fold back, bust circumference, neck circumference, and waist back length, and pattern 2, pattern 4, and pattern 5 were made based on bust circumference and waist back length. As a result of the appearance evaluation, Pattern 3 was evaluated as the best pattern in all items except for the suitability of the center front length and the suitability of the side waist circumference position. However, it was evaluated as inappropriate in items such as the vertical side line, the suitability of the side waist circumference line position, the suitability of interscye fold back position and shape, and the suitability of the back shoulder dart position. Most of the pattern drafting methods are based on the size of the bust circumference, but other institutional methods are considered necessary when setting the neck circumference and shoulder length for 20s obesity women. In addition, it is also required to develop a method for setting the front center length due to abdominal protrusion.

This paper proposes the generation of several classes of frequency hopping patterns. which are derived by permutation, for an asynchronous frequency hopping spread spectrum multiple accecss system (FH/SSMA). The first class of hopping patterns is obtained by using a Latin square. The second class of hopping patterns is derived by generalizing the first class which is designed by using a permutation technique. The third class of hopping patterns is designed by using a rotational base of elements. We evaluate the hit property of the proposed classes of hopping patterns when these patterns are nutually shifted in an FH/SSMA system. Compared to the Reed Slolmon sequences generated by the conventional method, the sequence obtained by the permutation technique can reduce the number of hits among hopping frequencies in asynchronous time/frequency shift.

In this study, a 3D simulation program was used to produce a bodice prototype of a middle-aged male in their 40s and 50s and then analyze the appearance evaluation and airgap, sectional view, color distribution through virtual wearing to compare and analyze the differences between patterns. Through this, it was intended to provide basic data necessary for pattern development to companies that manufacture and produce clothing for middle-aged men. As a result of analyzing, J pattern was analyzed as the most suitable body shape pattern for middle-aged men. E pattern was too tight and L pattern and N pattern had too much spaces. However, J patternt was analyzed that correction was necessary in setting center back and center front length. The aging phenomenon in which the back is slightly bent forward and shoulders are also inclined is expected to appear, so it is necessary to adjust the front-to-back length, shoulder angle, and shoulder length. It is considered that after developing the research pattern by modifying J pattern, it is necessary to develop a body shape prototype for middle-aged men through actual clothing experiments on middle-aged men.

The purpose of this study is to identify the context and pattern of Korea's self-sufficiency program based on the experiences of self-sufficiency program practitioner. To this end, this study applied the context-pattern analysis method, which was known as one of the qualitative research approaches, to provide proper and effective evaluations of self-sufficiency program. The analysis shows that the context of the self-sufficiency program consists of such sub-contextual components as 'market economy', 'social service system', 'self-sufficiency system', 'self-sufficiency program', 'self-sufficiency program participant', 'procedural experiences of the program', 'outcomes of self-sufficiency program', and 'meaning of the self-sufficiency program'. Furthermore, such patterns as 'decreased vitality of self-sufficiency system', 'service flow', 'journey to the self-sufficiency', and 'sequences to small success', were also presented. Based on these findings, this study suggests policy and practice implications, and subsequent related research topics.
