The conventional studies on equilibrium network design problem(ENDP) with fixed travel demand models assume that the future OD travel demand might not be changed even if the structure and the capacity of the network are improved. But this fixed demand assumption may loose its validity in the long-range network design because OD travel demand actually shifts with the network service level. Thus, it is desirable to involve the variable travel demand which is determined endogenously in the model in the optimal network design. In this paper a hi-level model formulation and solution procedure for ENDP with variable travel demand are presented. Firstly It is considered how to measure the net user benefits to be derived from the improved in link capacities, and the equilibrium network design problem considered here is to maximize the increase of net user benefit which results from a set of lift capacity enhancements within the budget constraints, while the OD travel demands and link travel times are obtained by solving the lower level network equilibrium problem with variable demand. And secondly sensitivity analysis is carried out to find the links to which the network equilibrium flow pattern is the most sensitive. Finally numerical example with simple network is carried out to test the validity of the model.

This study examined pre-service teachers' pedagogical content knowledge of fraction division in a context where they were asked to write a story problem for a symbolic expression illustrating a whole number divided by a proper fraction. Problem-posing is an important instructional strategy with the potential to create meaningful contexts for learning mathematical concepts, especially when real-world applications are intended. In this study, story problems written by 135 elementary pre-service teachers were analyzed with respect to mathematical correctness. error types, and division models. Patterns and tendencies in elementary pre-service teachers' knowledge of fraction division were identified. Implicaitons for teaching and teacher education are discussed.

This study was to explore experiences of Female Ex-offender's re-entry process to socialization. For this, 9 female ex-offenders who receive housing support by the Korea Rehabilitation Agency were interviewed and the Strauss and Corbin's ground theory is used to approach to the data. In open coding, 88 concepts, 33 subcategories, and 15categories emerged from the data. In axial coding, central phenomenon were 'indulge in self pity', 'being isolated female ex-offender'. Intervention condition was 'human cooperation system'. Strategies were 'increase the receptiveness', 'establish the foundation'. Consequences were 'finding the stability in the life', 'changing the life direction'. In selective coding, main theme was 'overcome social stigma through changing life-direction and acclimate to society', and four phases were derived from the data. Based upon this results outcome, need of female ex-offender in the process of social transition and their experience were discussed.

Nowadays, a lot of related data obtained from these research could be given a new present meaning to accomplish the original purpose of the whole research as a human genome project. In such a thread, construction of gene expression analysis system and a basis rank analysis system is being watched newly. Recently, being identified fact that particular sub-class of tumor be related with particular chromosome, microarray started to be used in diagnosis field by doing cancer classification and predication based on gene expression information. In this thesis, we used cDNA microarrays of 3840 genes obtained from neuronal differentiation experiment of cortical stem cells on white mouse with cancer, created system that can extract informative gene list through normalization separately and proposed combination method for selecting more significant genes. And possibility of proposed system and method is verified through experiment. That result is that PC-ED combination represent 98.74% accurate and 0.04% MSE, which show that it improve classification performance than case to experiment after generating gene list using single similarity scale.

가뭄으로 인해 발생할 수 있는 가장 심각한 피해는 용수 부족으로 인한 수자원 시스템의 용수공급 실패이며, 따라서 가뭄 위험도는 사용 가능한 용수의 부족과 관련하여 정량화되어야 한다. 이러한 맥락에서 수자원 시스템의 가뭄 위험도를 평가하기 위해 주로 신뢰도(reliability), 회복도(resiliency) 및 취약도(vulnerability)와 같은 세 가지 이수안전도 평가지표가 사용된다. 이러한 평가지표는 각각 용수공급 실패가 평균적으로 얼마나 자주 발생하는지, 얼마나 오래 지속되는지, 또한 어느 정도의 규모로 발생하는지를 위험도를 정량화하는 것으로, 용수공급 실패사상의 빈도, 지속기간 및 심도를 나타낸다. 본 연구에서 DRI(Drought Risk Index)는 신뢰도, 평가도 및 회복도의 가중평균값으로 정의되며, 이는 지속기간과 심도를 변수로 하는 이변량 가뭄빈도해석과 같은 변수를 공유한다. 본 연구에서는 두 가지 형태의 DRI 를 이용하여 지역 가뭄 위험도 평가 기준 산정 방안을 제시하였다. DRI_O(observed DRI)는 용수부족 시계열을 통해 산정된 공급실패 사상으로부터 산정되며, DRI_D(designed DRI)는 이변량 빈도해석을 통해 산정된 특정 지속기간을 갖는 확률가뭄심도로부터 계산된다. 기후변화 시나리오를 이용해 DRI_O 를 산정함으로써 미래의 이수안전도를 예측할 수 있으며, 이를 DRI_D 와 비교하여 지역의 용수부족으로 인한 가뭄 위험도를 산정하는 방법을 제안하였다. 또한 기존에는 주로 과거 최대 가뭄사상을 목표안전도로 설정하였으나 DRI_D 를 이용하여 보다 현실적인 목표안전도를 설정할 수 있다. 낙동강 권역의 10 개 중권역의 10 개 기후변화 시나리오를 대상으로 분석을 수행한 결과 병성천 유역과 형산강 유역이 각각 최저 및 최고 위험도를 갖는 것으로 분석되었으며, 지역 안전도 기준은 평균적으로 재현기간 5-20 년 사이의 범위를 갖는 것으로 나타났다.

In this paper, we present a morphosyntactic and semantic study of the concessive conjunctive phrase [todavía que] in the Andean and River Plate areas of Latin America. Real Academia $Espa{\tilde{n}}ola$(2009) describes that the adverb todavía occurs in a variety of focus-sensitive environments and specially, in the Andean and River Plate areas, the phrase [todavía que] participates in the concessive constructions and triggers an additive interpretation. It is well known that the Quechuan suffix '-raq' and the Aymaran suffix '-raki' have the meaning of todavía which is characterized as a additive particle. Due to the absence of the paratactic relationship between the mentioned Spanish adverb and those indigenous suffixes, the adverb todavía in [todavía que] is used as a additive focalizer. We assume that these morphosyntactic and semantic properties are derived from the language contact of Quechua-Spanish and Aymara Spanish. Based on this assumption, we will further assume that the etymological peculiarity of todavía as a universal quantifier is closely related to the reading of [todavía que] as a Scalar Additive Concessive Conjunctive Phrase.
