Mobile devices have become attractive learning devices for education. The digitalization of the higher education system in Sri Lanka by 2020 is part of the government's effort to modernize and enhance the country's overall education system particularly in view of the COVID-19 pandemic. Theoretically, this study contributes to the M-Learning model in higher education institutions via the integration of literature on technology adoption (TAM and UTAUT) with the variables of Perceived Usefulness, Perceived Ease of Use, Attitude, Effort Expectancy, Social Influence, and Facilitating Condition. The attitude towards M-Learning amongst higher education students was gauged via an online questionnaire survey. The convenience sample comprised 344 students from the Advanced Technological Institutes (ATI) in Batticaloa District, Sri Lanka. Descriptive statistics, a measurement, and structural model, and hypotheses testing were used to analyze the derived data. The findings indicate that mobile learning is significantly affected by perceived ease of use, social influence, effort expectancy, and facilitating condition, but negatively affected by attitude and perceived usefulness. The exhaustive literature review revealed that there are very few M-Learning studies related to digital learning in the context of higher education in the Batticaloa district.

동물은 마음을 갖고 있는가? 우리는 동물의 마음을 실제로 잘 알 수 없기 때문에 동물과의 관계를 통해 동물의 마음을 추정할 가능성이 높다. 본 연구에서는 동물을 사랑하는 태도와 고기를 먹는 행동에 대한 모순적 관계를 동물에 대한 마음지각의 맥락에서 두 개의 연구를 통해 검증하였다. 연구 1에서는 다양한 동물에 대한 마음지각을 경험의 차원과 주도성의 차원에서 분석하였다. 연구 2에서는 소를 고기로 기술한 실험조건과 고기가 아닌 동물로 기술한 통제조건에서 소와 성적 객체화된 여성에 대한 마음지각을 각각 측정하였다. 그 결과 연구 1에서는 동물에 대한 마음지각의 정도가 높을수록 고기를 먹는 행동을 도덕적으로 옳지 않은 것으로 판단하는 평정점수가 높았다. 연구 2에서는 소를 고기로 기술한 실험조건에서 통제조건보다 소와 성적 객체화된 여성에 대한 마음지각이 통제조건보다 낮게 나타났다. 따라서 동물이 '고기'로 제시되는 상황에서는 동물에 대한 마음지각의 조정을 통해 동물을 해치는 행동에 대한 심리적 불편감을 감소시킬 가능성을 생각해볼 수 있다. 이 결과는 인지부조화이론에 따라 고기를 먹는 행동과 동물에 대한 태도의 차이에서 발생하는 심리적 불편감을 줄이고자 동물에 대한 마음지각을 조정하는 것으로 해석할 수 있다. 또한 동물에 대한 객체화는 인간에 대한 객체화 및 마음지각에 영향을 끼침을 추정해볼 수 있다. 이 결과는 마음지각, 인지부조화이론 및 객체화이론이 일상에서의 도덕성과 연관된 태도와 행동의 모순적 관계를 설명하는데 유용함을 보여준다.

Speech articulators are coordinated for the purpose of segmental constriction in terms of a task. In particular, vertical jaw movements repeatedly contribute to consonantal as well as vocalic constriction. The current study explores vertical jaw movements in conjunction with bilabial constriction in bilabial stop /p/ in the context /a/-to-/a/. Revisiting kinematic data of /p/ collected using the electromagenetic midsagittal articulometer (EMMA) method from seven (four female and three male) speakers of Seoul Korean, we examined maximum vertical jaw position, its relative timing with respect to the upper and lower lips, and lip aperture minima. The results of those dependent variables are recapitulated in terms of linguistic (different word boundaries) and paralinguistic (different speech rates) factors as follows. Firstly, maximum jaw height was lower in the across-word boundary condition (across-word < within-word), but it did not differ as a function of different speech rates (comfortable = fast). Secondly, more reduction in the lip aperture (LA) gesture occurred in fast rate, while word-boundary effects were absent. Thirdly, jaw raising was still in progress after the lips' positional extrema were achieved in the within-word condition, while the former was completed before the latter in the across-word condition. Lastly, relative temporal lags between the jaw and the lips (UL and LL) were more synchronous in fast rate, compared to comfortable rate. When these results are considered together, it is possible to posit that speakers are not tolerant of lenition to the extent that it is potentially realized as a labial approximant in either word-boundary condition while jaw height still manifested lower jaw position in the across-word boundary condition. Early termination of vertical jaw maxima before vertical lower lip maxima across-word condition may be partly responsible for the spatial reduction of jaw raising movements. This may come about as a consequence of an excessive number of factors (e.g., upper lip height (UH), lower lip height (LH), jaw angle (JA)) for the representation of a vector with two degrees of freedom (x, y) engaged in a gesture-based task (e.g., lip aperture (LA)). In the task-dynamic application toolkit, the jaw angle parameter can be assigned numerical values for greater weight in the across-word boundary condition, which in turn gives rise to lower jaw position. Speech rate-dependent spatial reduction in lip aperture may be able to be resolved by means of manipulating activation time of an active tract variable in the gestural score level.

This study explores experiences of housewives with infants' Pumasi child rearing community(i.e, communal child rearing community). A concrete context of pumasi child rearing of housewives with Infants was found. Results were as follows: The backgrounds of participation in pumasi child rearing community are isolated condition of child rearing and housewives' needs to find way of communication with others. Pumasi child rearing communities give meaningful experiences. They meet the developmental needs of both mothers and children and also provide various parenting models and skills, give a high value to individual child rearing, develop an everyday life community and strengthen the health of communities.

In this paper, a scheme to increase the throughput of RFID systems is presented, which considers the capture effect in the context of framed ALOHA protocol. Under the capture model in which the probability of one tag is identified successfully depending on the number of tags involved in the collision, two probabilistic methods for estimating the unknown number of tags are proposed. The first method is the maximum likelihood estimation method, and the second method is an approximate algorithm for reducing the computational time. The optimal frame size condition to maximize the system throughput by considering the capture effect is also presented.

The purpose of this study is to understand the trends of urban housing in the age of modernization in Western cities since 1970's, and to provide the useful data for diversifying urban housing types in Korea. Although the housing types can be categorized in many ways according to the points of view, this study classifies 11 types by a criterion of urban composition elements. Among 11 urban housing types, one type, free-standing slab structure, has been mainly applied to Korean situation. The reason might be that the free-standing structure type is the most efficient one in terms of land use and block organization, but it results in a monotonic condition of urban housing blocks. Therefore, taking local characteristics and urban contexts in Korea into consideration, the future urban housing design should be developed in different ways of making local life styles possible in them, by adopting various types of Western urban housing precedents.

This survey was performed to gain basic information for the development of new protective clothing of high acceptability in pesticide splaying among small size farmers. The rate of protective clothing wearing was low during pesticide spray although they understand its necessity. The reason for this low acceptability was related to the heat stress and reduced work efficiency deriving from wearing protective clothing. Instead of wearing they tend to carry out spray work while the ambient temperature is not to high. In the similar context, they rather intend to spray in consideration of weather condition instead of wearing protective clothing in the future. However, they are willing to purchase protective clothing if desirable products are developed: the clothing need to be efficient in both protection and work performance; the fanciness in design is not a requisite. This survey result will provide information necessary for the direction of new protective clothing development.

It is essential to update the model with reflecting observation or inspection data for reliability estimation of existing structures. Authors proposed updated reliability analysis by using Particle Filter. We discuss how to apply the proposed method through numerical examples on reinforced concrete structures after verification of the method with hypothetical linear Gaussian problem. Reinforced concrete structures in a marine environment deteriorate with time due to chloride-induced corrosion of reinforcing bars. In the case of existing structures, it is essential to monitor the current condition such as chloride-induced corrosion and to reflect it to rational maintenance with consideration of the uncertainty. In this context, updated reliability estimation of a structure provides useful information for the rational decision. Accuracy estimation is also one of the important issues when Monte Carlo approach such as Particle Filter is adopted. Especially Particle Filter approach has a problem known as degeneracy. Effective sample size is introduced to predict the covariance of variance of limit state exceeding probabilities calculated by Particle Filter. Its validity is shown by the numerical experiments.
