  • The main objective of this paper is to test the major prediction of the Aspect Hypothesis on interlanguage narratives collected from 171 Ibibio ESL learners in a classroom setting using sets of picture stories. Aspect Hypothesis predicts that lexical aspectual classes of verbs would determine the pattern of acquisition and distribution of tense-aspect morphology at the very early stages of L2 acquisition of tense-aspect verbal morphology. That is, telic verbs would be marked with the past tense-aspect verbal morphology before atelic verbs in the interlanguage of ESL learners irrespective of their L1 background. The results of our data analyses show a significant effect from the lexical aspect on the acquisition and distribution of tense-aspect morphology with chi-square statistics of ($x^2=196.92$,df = 6, n = 1664, p = <.0001). However, the effect of the lexical aspect is shown to be more prominent among Ibibio ESL learners at higher levels of proficiency. This is contrary to the prediction regarding Aspect Hypothesis. The paper concludes that the influence of the lexical aspect on the pattern of acquisition and distribution of tense-aspect morphology may be universal but the actual point along the developmental pathway when such influence is obtainable is yet to be determined. This calls for more research into the pattern of the L2 acquisition of tense-aspect verbal morphology.

  • The purpose of this study was to compare dietary culture consciousness of rural and urban housewives through a nationwide survey. Interviewers interviewed 500 housewives(250 in rural and 250 in urban) using closed-ended questions. The dietary culture consciousness was divided into two parts of traditional aspect (dietary habit and ritual diet) and desirable aspect (food choice and nutrition knowledge). Each domain consisted of six items. Results of the study are summarized as fellows : 1) As a whole, dietary culture consciousness of rural housewives was more traditional than that of urban housewives in traditional aspect, and there was no difference of consciousness between rural and urban housewives in desirable aspect. 2) There was significant difference at 1% level between two groups in traditional aspect and there was no difference in desirable aspect. 3) By the analysis of each item, there was significant difference between two groups in 14 items. Especially, the item of westernized breakfast pattern was more acceptable in urban housewives than in rural. 4) In relationship between socio-demographic characteristics of housewives and dietary consciousness of them, age, educational level and religion of housewife were significant in traditional aspect, and so were educational level and job experience of housewives in desirable aspect. Dietary consciousness of rural housewives' was influenced by job experience (in traditional aspect) and age of housewives and level of living (in desirable aspect) In the case of urban housewives, level of living was significant in traditional aspect.

  • Acoustic side-aspect target strength (TS) of living Japanese anchovy (Engraulis japonicus) was measured at 120kHz during in situ experiments. The data were collected by lowering and horizontally projecting the splitbeam transducer into the anchovy school. For analysis and interpretation of the side-aspect TS data, acoustic theoretical model, based on the fish morphology, and dorsal-aspect TS data were used. Total length of the anchovy ranged from 6.6 to 12.8cm (mean length 9.3cm). The side-aspect TS distributed between -40 and -55dB, has an obvious length dependency. The mean side-aspect TS of the anchovy was -47.8dB, and the TS was about 2dB higher than mean TS generated from dorsal-aspect measurements. With reference to maximum TS, the results of the side-aspect TS were distributed within the range of the theoretical and dorsal-aspect TS. Apparently these tendency indicates that side-aspect TS measured from the study is useful data. These in situ measurements of side-aspect TS can be applied to improve acoustic detection and estimates of the anchovy, and is necessary to measure with a various frequency and length for making enhance data.

  • Three dimensional numerical studies were carried out to investigate the effect of aspect ratio on gas slip flow in rectangular microchannels. We focused on aspect ratio effect on slip velocity, pressure distribution and mass flow rate. As aspect ratio decreases the wall slip velocity also decreases. As a result nonlinearity of pressure distribution increases. The slip velocities on sides and top/bottom walls are different and this difference decreases with increasing aspect ratio. These two velocities are equal when aspect ratio is 1. The ratios of slip mass flow rate over noslip mass flow rate increases with increasing aspect ratios.

  • 동적 Aspect 프로그래밍(Aspect-Oriented Programming : AOP)은 로깅과 같은 비 기능적인 부분을 모듈화할 수 있도록 해주는 새로운 프로그래밍 기법이다. AOP는 절러 클래스에 영향을 미치는 행위들을 재사용 가능하도록 Aspect로 캡슐화 시켜준다. 기존의 Aspect 위버(weaver)에서는 Aspect를 위빙 할 경우, 새로운 서비스나 메소드를 추가하고자 한다면 서브클래스를 별도로 상속을 해주어야하며, 이로 인해 코드의 라인수가 증가되며, 수행 시간도 느려지게 된다. 이러한 문제점을 해결하기 위하여 동적 Aspect 위버 상에 Decorator 패턴을 적용하여 별도의 서브클래스를 상속하지 않고, 필요한 메소드만을 추가하여 위빙시키고, Aspect의 join point에 훅(hook)을 첨가하여 불필요한 메소드의 실행을 제거해준다. 이로 인해 수행속도와 재사용성을 증가시킬 수 있게 된다.

  • This paper investigates the aspect-ratio locking of the isoparametric 8-node quadrilateral (QUAD8) element. An important finding is that, if finite element solution is carried out with in exact arithmetic (i.e., with no truncation and round off errors), the locking tendency of the element is completely avoided even for aspect-ratios as high as 100000. The current finite element codes mostly use floating point arithmetic. Thus, they can only avoid this locking for aspect-ratios up to 100 or 1000. A novel method is proposed in the paper to avoid aspect-ratio locking in floating point computations. In this method, the offending terms of the strain-displacement matrix (i.e., $\mathbf{B}$-matrix) are multiplied by suitable scaling factors to avoid ill-conditioning of stiffness matrix. Numerical examples are presented to demonstrate the efficacy of the method. The examples reveal that aspect-ratio locking is avoided even for aspect-ratios as high as 100000.

  • Aspect-Oriented Software Development is new software development method. It has many advantages related to software performance, maintenance and repair. Also it offers modularization method to a existing programming language for secondary function such as security and fault tolerance. But the present problem is that we have to use new aspect-oriented programming language. Further more when we apply Aspect to legacy system, we have to recompile the source code in order to build software system based on AOSD. In this paper, we propose and design Connector that can be composed with Aspect in legacy system dynamically. To elaborate this work, we use the information of operations about Core and Aspect, and the information of pointcut described with XML. We validate that the proposed Connector has features such as no need of new compiler, no recompilation and no modification of legacy system through case study.

  • At the product design and development stage, the main criteria selecting a design alternative were performance aspect as well as cost aspect of a product. Ongoing new paradigm shifts such as low carbon green growth, climate change mitigation, sustainable society development urged considering environmental aspect of a product at the product design and development stage. Up to recently, only cost aspect except performance of a product was considered at the railway vehicle design process. Therefore, it is needed to develop a method that may consider environmental aspect of a product at the railway vehicle design process. Lee (2011) proposed that a method of an integration assessment of environmental aspect and cost aspect based on GHG emission instead of based on monetary value. This study conducted that apply the method of Lee (2011) to design alternative selection process of a railway vehicle. From the integrated view of environmental and cost aspect, the reference product and design alternatives are assessed and compared.
