  • Traditional business process management systems provide verification tools of process models to deploy and automate the models. However, there are not so many studies on how to maintain systematically collaborative process models such as supply chain processes when companies are willing to change and update the collaborative process models. In this paper, we analyze change patterns of collaborative processes and declare 19 change patterns. In addition, we apply the change patterns to the process interoperability patterns in order to identify the change problems in case of independent process changes of collaborative processes. As a result, we devise an independency checking algorithm of process changes in collaborative processes.

  • In this study, a land pollutant load calculation method in TMDLs was improved to consider climate change scenarios. In order to evaluate the new method, future change in rainfall patterns was predicted by using SRES A1B climate change scenarios and then post-processing methods such as change factor (CF) and quantile mapping (QM) were applied to correct the bias between the predicted and the observed rainfall patterns. Also, future land pollutant loads were estimated by using both the bias corrected rainfall patterns and the enhanced method. For the results of bias correction, both methods (CF and QM) predicted the temporal trend of the past rainfall patterns and QM method showed future daily average precipitation in the range of 1.1~7.5 mm and CF showed it in the range of 1.3~6.8 mm from 2014 to 2100. Also, in the result of the estimation of future land pollutant loads using the enhanced method (2020, 2040, 2100), TN loads were in the range of 4316.6~6138.6 kg/day and TP loads were in the range of 457.0~716.5 kg/day. However, each result of TN and TP loads in 2020, 2040, 2100 was the same with the original method. The enhanced method in this study will be useful to predict land pollutant loads under the influence of climate change because it can reflect future change in rainfall patterns. Also, it is expected that the results of this study are used as a base data of TMDLs in case of applying for climate change scenarios.

  • Previous researches on Korean intonation have been mainly focused on $F_0$ target frequencies, $F_0$ slope, and the duration of intonation patterns. This study investigated Korean intonation patterns, both boundary and phrasal tones, in relation to the $F_0$ percentage change between pitch targets. We measured the percentage change between the pitch targets of both boundary and phrasal tones. Additionally, the $F_0$ change between the preceding pitch target and the first pitch target of the boundary tone and the $F_0$ targets of the sequence of two LH phrasal tones ('LH + LH') were also measured. Two phrasal tones, LHLH and HLH, were compared with 'LH + LH' and the 'HLH' in the LHLH pattern respectively. We found that the percentage change between pitch targets in the phrasal tone is fixed to some extent. This helped explain why the slope of the phrasal tone is closely related to the number of syllables and the duration of the phrasal tone as discussed in previous studies. Since we analyzed the intonation patterns with the utterances from a large speech corpus, the results of this paper are expected to be used in building a larger annotated corpus of Korean.

  • This study will analyze the data of Kyongbu & Honam Line whether how much the weather change has an effect on the change of transportation modes and check the pattern of customer's behavior and investigate the influence on the changing transportation modes. Especially, this study will confine to the rainfall and snowfall out of various weather causes, and the questionnaire investigation is used to know the sensitivity of customer's patterns selecting transportation modes in accordance with weather change, and the research result will be used to make a marketing strategy & efficient train operation.

  • This is an effort to review epidemiological research on developmental patterns of drinking behavior among youth from adolescence to young adulthood. Selected correlates for changes in drinking behavior include age, antisocial behavior, family influence, and sociodemographic characteristics such as gender, ethnicity and socioeconomic status. An emphasis is given to the relationship between antisocial behavior and developmental patterns of drinking behavior. Also, this review regards observed particular patterns of drinking behavior as being contextualized by group to which individuals belong.

  • 내장 자체 테스트 과정에서 의사 무작위 패턴 생성기에 의해 만들어진 패턴들은 효율적인 고장 검출을 제공하지 못한다. 쓸모없는 패턴들은 테스트 시간을 줄이기 위해 제거하거나 수정을 통해 유용한 패턴으로 바꾸어야한다. 본 논문에서는 LFSR에서 생성하는 의사 무작위 패턴을 수정하고 추가적인 유효 비트 플래그를 사용하여 테스트 길이를 개선하고 높은 고장 검출률을 높이는 방법을 제안하고 있다. 또한 쓸모없는 패턴을 제거하거나 유용한 패턴으로 변경하기 위해 reseeding 방법과 수정 비트 플래그 모두 사용한다. 패턴을 수정할 때는 테스트 길이를 줄일 수 있도록 비트의 변화가 가장 적은 수를 선택한다. 본 논문에서는 단일 고착 고장만을 고려하였으며 결정 패턴을 사용하는 seed를 통해 100%의 고장 검출률을 얻을 수 있다.

  • The study has examined about the origin and change of traditional Japanese dress "Kosode" and classified it according to its ages and also classified its patterns which appeared on the Kosode by its kinds, and divide the patterns with constituent method and expressional method and so, studied and analyzed them with type of patterns according to the change of the times. The result of research were as follows: 1. Subject of patterns that appeared on the Kosode was used with mainly plant pattern, animals pattern, pictorial pattern, artificial pattern, and abstract patterns. 2. Expressional method of this patterns was mostly expressed simply with tie dyeing in ancient times, but it changed complex its expressional method and diversely due to the development of common's culture as time goes on. 3. For the arrangement of its pattern were arranged regularly mostly make demarcate and though they are as if seemed dispersed, but a characteristic that can find regulations in it. 4. Transition of patterns that appeared on the Kosode it developed at the beginning of ancient syouboon, Katasuso pattern and Katamigaori patterns at the samurai's society in the medieval society and developed to Koicho kosode and Kambun kosode in modern times.

  • In this paper, we deal with the teaching of the approaching to algebra based on patterns. The change of algebra curriculum has been undergoing in many countries including USA, England, Australia. The traditional algebra curriculum starts with letters(variables), algebraic expressions, and equations. But these formal approaching method has many difficulties in teaching school algebra. Therefore the new algebra curriculum has to be needed, and the approaching to algebra based on patterns has been focused. In this paper, we compare this new approaching to algebra based on patterns to the traditional algebra curriculum. Next we consider the NCTM algebra curriculums based on Standards (1989) and Standards 2000(2000), Britannica textbook series(1998) based on RME. Also we investigate our pattern approaching in our curriculum and discuss some problems from the perspective of the approaching to algebra based on patterns.

  • An attempt was made to study the subdivision of Korea by the annual amount and the annual change pattern of monthly precipitation days(that is one of the important elements of the precipitation characteristics), using the mean values for the years 1961-1990 at the 68 stations. The amplitudes of annual change were normalized and using these values, the principal component analysis was applied to determine the annual change patterns. The results show that they are expressed by the combinations of the three change patterns in almost whole regions of Korea. As a result,the annual change pattern of precipitation days in Korea is classified into 8 types from A to e,in detail, 36 types from A0 to e$\circled2$.And regional division of precipitation days in Korea is divided into 13 regions from I a to IIIC,into detail, 41 regions from I no to IIICl.
