  • This study aims to examine two hypothetical models for the variables of students' environmental perspective. First hypothetical model is the mediating role of recognition and familiarity between aesthetic and negativistic perspectives. Second hypothetical model is the separate path from humanistic to dominionistic perspectives. One hundred four tenth grade students participated in this study. We used Pearson correlation, partial correlation, and path analysis to examine the fitness of hypothetical models. The findings showed that the mediating role of recognition and familiarity between aesthetic and negativistic perspectives were statistically accepted. To prevent students' bias for fancy or gross animals, the learning (for instance, recognition and familiarity) may play role in reducing the bias. Second, there were two differential paths from humanistic to dominionistic perspectives (ecologistic-naturalistic path and scientistic-utilitarian path). While ecologistic-naturalistic path does not reach dominionistic perspective, scientistic-utilitarian path does reach dominionistic perspective. To prevent students' dominionistic perspective for nature, they need to understand ecologistic-naturalistic minds for the nature.

  • In component based development, component modeling for understanding and analyzing is the important part and is used to improve reusability. Generally, components are need to be divided into two types according to their usages, where the developer and assembler are usually different. To make a good component model, a complete component and interface specification for those components are needed. And the component model needs to adept two different views of developer and assembler. In this paper, we suggest two different views of component model that is related to views from developer and assembler, and we expand UML. Also we validate the efficiency of the suggested model by developing and applying a tool for building, managing and automatic transformation.

  • Among the customer-oriented data used to comprehend the customer, the user review data has received much attention as it provides insights into customer opinion in a detailed and large-scale manner; many customers have come to rely upon and trust the user reviews. Many application developers are cognizant of the importance of user reviews, so they monitor and respond to these reviews. However, due to the absence of a systematic method, developers have been investing their time and money without clear correlation to the customer satisfaction. Therefore, this paper suggests a systematic method to select user reviews from the application market using the Kano Model that deals with customer satisfaction and service quality, thereby maximizing the customer satisfaction under the given time period and budget. This method is constructed in the following phases: the user review collection and requirement elicitation phase in which the developers collect user reviews from the application market and elicit requirements, the Kano Model application and selection phase in which the Kano Model is applied to the elicited requirements and selection occurs based on the quality type, and the stakeholder review and redefinition phase in which relevant personnel gather to review and redefine requirements from an internal perspective.

  • 목 적 : 씨클로포스파미드(Cyclophosphamide, CP)는 많은 종양 질환에서 단독 혹은 다른 화학요법과 함께 사용되는 항암제이다. CP의 독성과 부작용으로 출혈성 방광염이 많은 문제를 일으키고 있다. CP로 유도된 방광염 모델은 하부요로의 통증질환을 이해하기 위한 내장성 통증의 주요한 모델로 사용되고 있다. 본 연구는 암컷 백서에서 CP로 유도된 방광의 과활동성에 대한 침의 효과를 관찰하기 위해 요류역학검사를 수행하였다. 방 법 : CP (200 mg/kg) 투여 18시간 후에, 지속적 생리식염수 관류 (분당 0.04 ml) 로 방광내압 측정을 통해 방광기능을 평가하였다. 관류 2시간 이후부터, 위중/곤륜 100 Hz, 위중/곤륜 2 Hz, 족삼리/삼음교 100 Hz, 족삼리/삼음교 2Hz 전침 자극을 하여 자침 전후의 방광수축간격(intercontraction interval, ICI)을 비교하였다. 결 과 : 방광내압 측정하는 동안, 방광수축간격은 CP로 유도된 방광염 모델에서 정상군에서 보다 유의하게 짧았다. CP로 유도된 방광염 모델에서, 위중/곤륜 100Hz 전침 자극은 자침 전보다 통계적으로 유의하게 $40.6\;{\pm}\;10.9\;%$ 증가시켰고, 2Hz 전침 자극은 자침 전보다 현저하게 $22.1\;{\pm}\;13.7\;%$ 증가시켰다. 반면에, 족삼리/삼음교 전침 자극은 100Hz, 강 2Hz 전침 자극 각각 $13.7\;{\pm}\;8.1\;%,\;8.7\;{\pm}\;4.5\;%$ 약간 증가시켰다. 결 론 : 족태양방광경의 경혈에 100Hz 전칩 자극을 하여 CP로 유도된 방광의 과활동성을 억제하였다. 이러한 결과는 침 자극으로 CP로 유도된 혹은 다른 종류의 방광염을 치료하는데 효과적일 것임을 시사한다. 또한, 특정 경락의 경혈과 해당 장부의 질환의 치료에 연관성을 보여준다.

  • An intuitive understanding of the dynamic pattern generation in asymmetric networks may be considered an essential component in developing models for the dynamic information processing. It has been reported that the neural network with cyclic connections generates multiple limit cycles. The dynamics of discrete time network with cyclic connections has been investigated intensively. However, the dynamics of a cyclic connection neural network in continuous-time has not been well-known due to the considerable complexity involved in its calculation. In this paper, the dynamic behavior of a continuous-time cyclic connection neural network, in which each neuron is connected only to its nearest neurons with binary synaptic weights of ${\pm}1$, has been investigated. Furthermore, the dynamics and stability of the network have been analyzed using a piece-wise linear approximation.

  • This study presents a contents model designed for business records that require long-term preservation. The contents model is based on the PREMIS(Preservation Metadata: Implementation Strategies) data model and the ISAD(G)(General International Standard Archival Description). The study selected the record collection of "the records of the overseas petroleum business and oil field development of A company located in B country." This collection requires permanent preservations by the nation and even beyond. It was attempted to establish the concepts of intellectual objects in the PREMIS data model to apply the PREMIS data model to the business records specifically. In other words, the study established the principles for differentiation of the classes in the record contents and the hierarchy structure, and the hierarchy model was developed for business records contents to derive the business records model based on those principles.

  • The statistical modeling of input random variables is necessary in reliability analysis, reliability-based design optimization, and statistical validation and calibration of analysis models of mechanical systems. In statistical modeling methods, there are the Akaike Information Criterion (AIC), AIC correction (AICc), Bayesian Information Criterion, Maximum Likelihood Estimation (MLE), and Bayesian method. Those methods basically select the best fitted distribution among candidate models by calculating their likelihood function values from a given data set. The number of data or parameters in some methods are considered to identify the distribution types. On the other hand, the engineers in a real field have difficulties in selecting the statistical modeling method to obtain a statistical model of the experimental data because of a lack of knowledge of those methods. In this study, commonly used statistical modeling methods were compared using statistical simulation tests. Their advantages and disadvantages were then analyzed. In the simulation tests, various types of distribution were assumed as populations and the samples were generated randomly from them with different sample sizes. Real engineering data were used to verify each statistical modeling method.
