This study explored the common response profiles in the narrative stories of typically developing 5 year-old Korean Children. Fourteen story stems from the MacArthur Story Stem Battery (MSSB, Bretherton, Oppenheim, & the MacArthur Story Stem Network, 1990) were administered to 156(85 boys and 71 girls) children recruited from 8 Kindergartens in the Seoul and Gyung-gi areas. The children's responses were aggregated into 5 dimensions, based on content themes and performance scores which included emotions expressed and narrative coherence using the MacArthur Narrative Coding System (Robinson, Mantz-Simmions, Macfie, & MacArthur Narrative Working Group, 2004). Data were analyzed by means of cluster analysis. 5 response profiles emerged over the course of this research : Prosocial, Anxiety, Dysregulated aggression, Anxious/Avoidance, and Avoidance profiles. When 14 story stems were grouped into 3 story contexts (stories included interpersonal conflicts, moral conflicts, and empathy) and were analyzed separately according to the story contexts, 3 common profiles (a Prosocial profile, a Constrained profile and an Anxiety profile) emerged across the story contexts, however, there were additional, unique profiles for each of the story contexts.

최근 상황인식 기술은 유비쿼터스 환경에서 중요한 이슈로 떠 오르고 있으며, 연구자들에 의해 많은 연구가 이루어 지고 있다. 상황인식 기술은 상황정보를 획득/가공하여 사용자에게 필요한 서비스와 정보를 제공하는 컴퓨터 시스템이다. 상황인식 시스템은 각종 센서로부터 발생하는 낮은 수준의 상황정보를 높은 수준의 상황정보로 변환하여 사용자에게 원하는 서비스를 제공하는 환경을 만들어 준다. 본 논문에서는 물리적인 스마트 공간에 존재하는 각종 센서로부터 얻어진 하위단계(Low level)의 Event driven 센서정보를 온톨로지 기반 상황정보로 모델링 하여 상위단계(High level) 상황정보로 변환하는 상황인식 모델링과 시스템을 제안한다. 또한 변환된 High level 상황정보는 가상공간에서 ECA(Event Condition, Action) 룰에 따라 사용자에게 언제 어디선지 사용자가 필요로 하는 능동적이고 지능적인 서비스를 제공하고, 스마트 오피스 환경에서 발표 도우미 서비스를 구현하였다.

Beverages can vary in their appropriateness depending on the context of their different uses; therefore, an intention to consume a beverage is likely dependent on the context of its use. This study associated the consumer acceptability of commercial beverage products examined in a previous study (Kim and others, 2013) with its appropriateness under different use contexts. Consumers (n=360) were divided into two conditions: blind and brand. Consumers rated appropriateness for 13 use contexts for each beverage product. The results indicated that the contextual appropriateness were significantly different among the beverage samples and seemed to be positively influenced by the acceptability of beverages. The beverages with higher liking scores were more appropriate in a greater number of contexts, including "when tired", "refreshing", and "rest". However, there were inappropriate contexts (e.g., "while weight watching", "after exercise", "with a meal", and "health care") regardless of degree of acceptability. In the brand condition, some differences in contextual appropriateness were observed when comparing results from the blind condition (e.g., "with a meal", "health care").

This paper reports experimental findings about the duration feature of the acoustic components of English stops in Korean speakers' voicing perception. In our experiment, 35 participants discriminated between recorded stimuli and digitally transformed stimuli with different duration features from the original stimuli. 72 sets of paired stimuli are generated to test the effects of the duration feature in various phonetic contexts. The result of our experiment is a complicated cross-tabulation with 540 cells defined by five categorical independent variables plus one response variable. To find a meaningful generalization out of this complex frequency table, we ran logit log-linear regression analyses. Surprisingly, we have found that there is no single effect of the duration feature in all phonetic contexts on Korean speakers' perception of the voicing contrasts of English stops. Instead, the logit log-linear analyses reveal that there are interaction effects among phonetic contexts (=C), the places of articulation of stops (=P), and the voicing contrast (=V), and among duration (=T), phonetic contexts, and the places of articulation. To put it in mathematical terms, the distribution of the data can be explained by a simple log-linear equation, logF=${\mu}+{\lambda}CPV+{\lambda}TCP$.

This study aims to consider interrelations and reasonability to inquiry elements of environment units in 10th Science textbooks of 7th curriculum on the basis of their inquiry contexts, processes and activities. Frequency of inquiry contexts is 59.9% of the highest value in natural environment context but is 4.0% of the lowest one in techno-industrial context. Measurements, inferences, predictions, experiments, data-interpretations, correlations, conclusionreveals in inquiries are in all the textbooks, but observations and classifications, hypothesis generations, controlling variables, experimental designs and generalizations are not in some textbooks. Discussions, experiments, investigations in inquiry activities are included in all the textbooks. However, inspections are not appeared in the all the books. Based on the above results, social and techno-industrial inquiry contexts in the varied scopes are necessary in the environment curricula with a unified direction. Inquiry processes with pro-environmental behaviors as a last goal might be given into the curricula, having tasks that could be understand unified inquiries. In addition, inspections with effectiveness might be thrown into the scene of education.

In this paper, we have proposed Auto- TSS, an automatic transcription module of three ambiguous symbols-period (．), colon (:) and slash (／)--using their linguistic contexts. Few previous studies have discussed the problems of ambiguities in reading those symbols into Korean alphabetic letters in order to improve the current Korean TTS (Text-To-Speech) systems. We have classified 9 different reading formulae of the three symbols, analyzed their left and right contexts, and investigated selection rules and distributions between the symbols and their contexts. Based on these linguistic features, 30 stereotyped patterns, 53 rules and 5 heuristics determining the types of reading formulae are investigated for Auto-TSS. This module works modularly in 4 steps. The pilot test was conducted with three test suites, which contain respectively 6,979, 3,491 and 2,450 morpheme clusters containing at least one of three ambiguous symbols and Arabic numeral(s). Encouraging results of 94.3%, 93.0%, 94.2% accuracy were obtained for the test suites. Our next phases are to develop a guessing routine for unknown contexts of the union symbols by using statistical information; to refine the proper nouns and terminology detecting module; and to apply Auto-TSS on a larger scale.

Background and Objectives: The study investigated vowel context effects on the perception of stop consonants in Malayalam. It also probed into the role of vowel context effects in determining the frequency of occurrence of various consonant-vowel (CV) syllables in Malayalam. Subjects and Methods: The study used a cross-sectional pre-experimental post-test only research design on 30 individuals with normal hearing, who were native speakers of Malayalam. The stimuli included three stop consonants, each spoken in three different vowel contexts. The resultant nine syllables were presented in original form and five gating conditions. The consonant recognition in different vowel contexts of the participants was assessed. The frequency of occurrence of the nine target syllables in the spoken corpus of Malayalam was also systematically derived. Results: The consonant recognition score was better in the /u/ vowel context compared with /i/ and /a/ contexts. The frequency of occurrence of the target syllables derived from the spoken corpus of Malayalam showed that the three stop consonants occurred more frequently with the vowel /a/ compared with /u/ and /i/. Conclusions: The findings show a definite vowel context effect on the perception of the Malayalam stop consonants. This context effect observed is different from that in other languages. Stop consonants are perceived better in the context of /u/ compared with the /a/ and /i/ contexts. Furthermore, the vowel context effects do not appear to determine the frequency of occurrence of different CV syllables in Malayalam.

교사가 자기평가를 통해 많은 평가 요소를 일일이 측정하기는 쉽지 않으며, 또한 평가기준 요소가 방대하거나 해당 내용이 추상적이고 형식적인 것이라면 그 기준의 달성 여부를 판가름하기란 쉽지 않을 것 같다. 이러한 인식 하에, 본 연구에서는 교사 전분성의 핵심 영역인 수업과 관련된 일련의 활동에 대하여 교사 자신의 자기평가 방법에 따라 측정 용이한, 즉 실제적 활용 가치 및 의미가 높은 수업평가를 위한 요소를 탐색하고자 하였다. 다만, 본 연구에서는 수업 상황에 관한 교사 지식의 부문에 초점을 두어 수학 수업평가 요소를 마련하고자 하였다. 이러한 연구 결과로부터의 기대는 합리적이고 효과성을 거둘 수 있는 평가기준이 마련되어 이를 토대로 교사의 수업 전문성 신장이 보다 적극적으로 고무됨으로서 교실 수업이 개선되도록 하는 데 도움이 되고자 함이다.
