The present study is a basic study for application of Augmented Reality (AR) to verb teaching for children with language developmental disorders and is intended to examine validity for the list of verbs at the beginning of development. To confirm the validity of the verbs list, the appropriateness of the verbs was evaluated by three professors with certification of KSLP (Korean Speech-Language Pathologist) working in the department of Speech-Language Pathology at the university. The motion validity test was conducted by showing motion implemented as AR to eight master's students in Speech-Language Pathology major, having them record verbs that came to their mind, and evaluating in the conformity. The second motion validity test was conducted by using 5-point Likert scales to 87 undergraduates in Speech-Language Pathology major and having them see the motions in AR and marked the degrees to which them see the motions conform to the relevant verbs on the scales. Using the SPSS 21.0 program, descriptive statics analyses of the results were conducted. Through this all process, thirty verbs were selected as having content validity. It could be seen that when AR based communication system are applied, things and backgrounds that complement the insufficient movements of motions and help motion recognition should be also provided. In future studies, the 3D images of the AR based communication system will be complemented and the content validity will be verified with typically developing children and the children with language developmental disorders.

This study explores the lexical-semantic structure of derived causative verbs in Korean based on Pustejovsky(1995)'s Generative Lexicon Theory (GL). Morphological causative verbs are derived from their root stems by affixing ‘-i, -hi, -li, -gi’ in Korean and the meanings of derived predicates are closely related to the meanings of their root verbs. In particular, the change of the ARGUMENT STRUCTURE by morphological derivation leads to the change of the EVENT STRUCTURE. The ARGUMENT STRUCTURES of derived causative verbs include a causer argument, which is added to the ARGUMENT STRUCTURE of their root verbs by means of the causative derivation. Their EVENT STRUCTURE has a headed process related to a causer and its result is the event which their root verbs denote. This approach can also suggest that the (in)directness of causative is dependent on is the semantics of its root verb.

The purpose of the study was to investigate the effects of task presentation methods (animation vs. picture) on verb naming abilities as a function of verb argument structures for normal elderly adults. Participants were categorized into the two groups: animation group(n=21) vs. picture group(n=21). Data for the animation group were from obtained from Sung and Choi (2012). Percent of accuracy for the verb naming task served as a dependent measure for statistical analyses. After the years of education was controlled as a covariate, a two-way mixed ANOVA was performed with the group as a between-subject factor and the argument structure(1-, 2-, and 3-place) as a within-subject factor. Results revealed that there was a significant interaction between the group and argument structure, whereas there were no main effects for either of the factors. The animation group performed better than the picture group for one-place verb, whereas the opposite pattern was observed for the three-place verbs. The results suggested that the presentation methods are one of the critical factors that influenced verb naming abilities in elderly adults.

For the survey of weed distribution in the cultivated upland of Korea, weed species were investigated at 2 field by crop of 2 myon per kun in 81 kun selected among the 139 kun of the whole country. 232 species in 46 families were observed, totally. From among the result, 165 species in 39 families the in winter crop field, 189 species in 41 families in the summer crop field were classified. 122 species in 34 families were emerged the from the upland crop field of the whole season. Further more, in the 10 dominant weed species which emerged from upland crop field, Alopecurus aequalis, Chenopodium album, slellaria media, Galium spurieum, Capsella bursa-pastoris and Rorippa islandica were dominated in the winter upland and paddy field, and that Erigeron canadensis, Cyperus amuricus, Equisetum arvense and Arenaria serpyllifolia were dominated in the winter upland field, additionally. Stellaria alsine, Bothriospermum tenellum, Trigonotis peduncularis and Polygonum arviculare were dominated in the winter cropping on drained paddy field, additionally. In the summer crop field, Digitaria sanguinalis, Portulaca oleracea, Acalypha australis, Echinochloa crus-galli, Setaria viridis, Persicaria hydropiper, Amaranthus lividus, commelina communis, Chenopodium album and Cyperecs amuricus were dominated.

웨어러블 컴퓨터는 사용자를 중심으로 의복과 기술이 결합된 기기로서 직관적이며 유연한 인터페이스가 요구된다. 현재 직관적인 입력방식으로 음성인식과 동작인식에 대한 연구가 활발하게 진행되고 있다. 동작인식의 경우 손동작을 이용한 장갑형태가 가장 많으며, 대부분 사용자 행동의 의미를 고려하지 않은 인위적인 제스처로 학습을 필요로 한다. 본 연구에서는 사용자가 일상적으로 하는 행동에서 의미를 추출하고, 웨어러블 컴퓨터의 인터페이스로서 적용가능성을 보고자 한다. 행동은 자극에 대한 신체의 움직임이다. 문헌을 통하여 신체의 움직임에 대한 66개의 동사를 추출하고 구체적인 움직임에 구문조사를 실시하였다. 조사된 구문에 대한 상황과 의미를 조사한 결과 행동은 의미에 따라 감정표현, 의사전달, 정보교류, 자기제어, 기기제어, 무의식적, 의례적의 7가지로 분류할 수 있었다. 그 중 의사소통과 대상을 제어하기 위한 행동을 중심으로 접근하였다. 행동의 의미와 현재 사용되고 있는 UI의 의미를 비교하여 인터페이스를 대응시켜 보았다.

This study is purposed to analyze the appearances and functions of ellipsis of case markers through the Hangul letters of Hyun-Poong Kwak's family in the early 17th century. Hangul letters appear more colloquial than typography, and ellipsis is the one of main features of it. Generally, 'ellipsis' occurs when a constituent of a sentence deliberately leaves out of a sentence, because it is repeated or can be deduced by the context or occasion. As Hangul letter is written for a specific person, 'ellipsis' occurs more often than typography written for unspecified individuals. The ellipsis of case markers are not an exception. The ellipsis has functions as follow. The first, function is 'brevity.' Communication can be more convenient by ellipsis. Next will be 'informality.' Informality caused by ellipsis can make people express their thoughts and feelings fluently and naturally. It is the reason that spoken language has more frequently occurred ellipses than written language. The third function is 'quickness.' The same information can be delivered more quickly by the sentence using ellipsis than not using. In the 21st Century, ellipsis is misused in netizen communication owing to the quickness. The last function should be 'the effect of a literary style.' The effects can embody through ellipsis such as 'rhythm effect', 'letter style effect', 'translation style effect.' As a result of analyzing ellipsis of case markers, frequency follows the order below.[subjective objective > Locative > Dative > Commutative > Instrumental]

Weed flora and floristic composition were reviewed in lowland rice field and upland crop area. For lowland rice field weed flora was not much changed since 1971. About 29 weed species belonged to 18 families were occurred. However, floristic composition of dominant weed species has greatly changed mainly due to introduction of herbicides. The predominant weed species in 1971 when herbicide was not used were Rotala indica, Eleocharis acicularis, Monochoria vaginalis, Echinochloa crus-galli, while these for in 1991 were Eleocharis kuroguwai, Sagittaria pygmaea, S. trifolia, Echinochloa crus-galli and M, vaginalis, respectively. In 1981 weed survey, E. crus-galli was no longer troblesome weed. However, this species became important again thereafter by introduction of herbicide mixtures with pyrazolate, bensulfuron-methyl or pyrazosulfuronethyl. For upland crop area, 216 weed species belonged to 46 families were recorded. One hundred and sixtyfive of these were grown in winter crop area while 189 weed species occurred in summer crop area, respectively. Among these, 138 weed species were grown in both crop seasons. In general, summer crops had less number of weed species compared to winter crops. Even though the dominant weed species varied by crop the most common weeds were Chenopodium album, Alopecunrs aqualis, Stellaria alsine and S, media for winter crops and Digitaria sanguinalis, Portulaca oleracea, Chenopodium album and Acalypha australis for summer crops, respectively.
