쓰기 장애를 가진 아동과 정상 초등학교 학생을 대상으로 그들의 글씨에 대해서 조사하였다. 전체적으로는 쓰기 장애 아동의 글씨가 정상 아동보다 크고, 글자 사이의 간격은 넓은 대신 단어 사이의 간격은 좁았다. 글씨의 크기는 남녀 모두 그리고 학년에 관계없이 차이를 보이고 있었고, 나이가 듦에 따라 글씨의 크기는 점점 작아졌으며 특히 여자에 있어서는 쓰기 장애 아동(r=-0.16)보다 정상 아동(r=-0.45)에서 작아지는 속도가 빨랐다. 글자 사이의 간격은 남학생의 경우 초등학교 1, 2학년 때에는 글자 사이의 획의 침범으로 인해 쓰기 장애 아동이 정상 아동보다 간격이 더 좁았는데, 이런 차이는 초등학교 3, 4, 5학년 때에는 거의 없어지고, 초등학교 6학년에 이르면 글자 사이의 간격이 정상 아동보다 더 넓어지는 것이 확인되었다. 여학생의 경우에는 쓰기 장애 아동이 정상 아동보다 글자 사이의 간격이 초등학교 1학년부터 지속적으로 넓었다. 이런 차이는 쓰기 장애의 기전이 남자와 여자가 서로 다르다는 것을 시사해주는 소견이었다. 단어 사이의 간격은 남녀 모두 그리고 모든 학년에서 쓰기 장애 아동이 정상 아동보다 좁았는데, 이는 우리말의 경우 띄어쓰기 문제가 쓰기 장애에서 상당히 중요한 부분임을 짐작하게 하는 단서였다. 글자 사이의 간격이나 단어 사이의 간격은 나이가 들수록 감소하는 경향을 보였지만 여학생의 경우 쓰기 장애와 정상 아동에서 연령과 단어 사이의 간격 사이에 의미 있는 상관관계를 나타내지 않아서 대조를 이루었다. 상관관계 분석에서는 글씨의 크기와 글자 사이의 간격 사이에 약한 상관관계를(r=0.11-0.15)보였으나 글자 사이의 간격과 단어사이의 간격은 서로 밀접한 상관관계를 나타내었다(r=0.99). 음운적 오류는 대개 종성(받침)에서 관찰되었다 특히 겹받침(ㄳ, ㄵ, ㄶ, ㄺ, ㄻ, ㄼ, ㄾ, ㄿ, ㅀ, ㅄ)을 제대로 기억해내지 못하였고, 구개음화나 음운의 동화로 인해 음가(音價)가 변하는 경우에 오류를 보였다. 의미적 오류는 두 군에서 그다지 빈도가 높지 않았다. 띄어쓰기의 오류는 음운적 오류와 상관관계가 높았고, 대체적으로 여자보다 남자에서 많았다. 이상을 종합하여 볼 때, 쓰기 장애 아동과 정상 아동 사이에는 글씨의 크기, 글자 사이의 간격, 단어 사이의 간격, 음운적 오류, 띄어쓰기 오류 등에서 분명한 차이를 보였고, 나이에 따라 변화하는데 정상 아동과 쓰기 장애 아동은 서로 발달 속도에서 질적인 차이를 보였다. 남자와 여자의 글씨는 초등학교 2, 3학년부터 명백한 차이를 보이면서 쓰기 장애의 유형도 둘 사이에 차이가 존재한다는 것을 확인할 수 있었다.

This paper centers around the etymological meanings of place names of the Kumkang region, restricting the discussion to a selected group of place names which make it possible to infer their cultural characteristics in the light of the latitudinal or longitudinal isoglosses. The legends of Komnaru and Choryongdae, for instance, derive directly from place names. Dialectal distribution is examined on the basis of the phonological features that are not very different between upper and lower reaches of the Kumkang river. The dialects get much more similar as they go further down to the lower region of the river. The original "Komanara(熊津)", also called "Northern Headland(北津)", underwent the sound change of Komannaru > Komkang > Kumkang(錦江), the last being alternatively abbreviated as Kum(錦). During the last half of the 14th century-around the close of the Koryo dynasty, that is-a literary work gave the beautified name "Nakhwa-am"(落花巖), meaning 'rock-bluff of falling flowers', to what was originally called Tasa-am(墮死岩), so-called because, in the year of 660 when the Paekje dynasty was being ravaged by the invading enemy, a number of court-ladies ended their lives by plunging into the river from there. It was 'a number of court-ladies'(諸後宮) who died; but by tradition of popular songs, the number has become "three thousand" - a case of hyperbole of course.

This paper analyzes the formation of Tianjin dialect by investigating the immigration situation in Tianjin in history, analyzing the rhyme phenomenon of Tianjin dialect and comparing Tianjin dialect with surrounding dialects. First of all, with the need of transferring grain from the south to the north after the Ming Dynasty, the canal-centered grain transportation industry developed, and the immigrants in Tianjin naturally began to increase. In the Qing Dynasty, a large number of commercial immigrants flowed into various areas of Tianjin with the expansion of Tianjin's urban scale. This way of immigration makes Tianjin dialect preserve some dialectal features of other regions. By comparing with other Mandarin dialects, it is found that this is not only a feature of Tianjin dialect, but also a common feature in other Mandarin dialects. Therefore, we can draw a conclusion that the opinion of considering the dialect of one region is the mother dialect of Tianjin dialect because a certain phonological feature of Tianjin dialect is the same as that of other specific area is not appropriate. On the other hand, these immigrant dialects, which well reflects the characteristics of Tianjin, just show that these dialects have formed the present Tianjin dialect in the form of integration after the Ming and Qing Dynasties.

This study investigated the influences of probabilistic accessibility of the word being produced - as determined by its usage frequency and neighborhood density - on native and high-proficiency L2 speakers' realization of six English monophthong vowels. The native group hyperarticulated the vowels over an expanded acoustic space when the vowel occurred in words with low frequency and high density, supporting the claim that vowel forms are modified in accordance with the probabilistic accessibility of words. However, temporal expansion occurred in words with greater accessibility (i.e., with high frequency and low density) as an effect of low phonotactic probability in low-density words, particularly in attended speech. This suggests that temporal modification in the opposite direction may be part of the phonetic characteristics that are enhanced in communicatively driven focus realization. Conversely, none of these spectral and temporal patterns were found in the L2 group, thereby indicating that even the high-proficiency L2 speakers may not have developed experience-based sensitivity to the modulation of sub-categorical phonetic details indexed with word-level probabilistic information. The results are discussed with respect to how phonological representations are shaped in a word-specific manner for the sake of communicatively driven lexical intelligibility, and what factors may contribute to the lack of native-like sensitivity in L2 speech.

The current study investigated the influence of age of L2 acquisition (AOA) and length of residence (LOR) in the L2 setting country on the production of voicing-conditioned vowel duration and spectral qualities in English by Korean learners. The primary aim was to explore the ways in which the language-specific phonetic features are acquired by the age of onset and L2 experience. Analyses of the archived corpus data produced by 45 native speakers of Korean showed that, regardless of AOA or LOR, absolute vowel duration was used as a salient correlate of voicing contrast in English for Korean learners. The accuracy of relative vowel duration was influenced more by onset age than by L2 experience, suggesting that being exposed to English at an early age may benefit the acquisition of temporal dimension. On the other hand, the spectral characteristics of English vowels were more consistently influenced by L2 experience, indicating that immersive experience in the L2 speaking environment are likely to improve the accurate production of vowel quality. The distinct influence of the onset age and L2 experience on the specific phonetic cues in L2 vowel production provides insight into the intricate relationship between the two factors on the manifestation of L2 phonological knowledge.

The early 20th century is a period of time when Korea confronted with the surging waves of modernization, and made a variety of internal reactions. The Korean language, not immune to the upheaval, also experienced new changes and gradually gained characteristics of today's Korean. Although scholars have not yet fully agreed upon the time division of Korean, Gabo reformation (1896) is usually considered to be the beginning of modern Korean. Thus, the early 20th century was also the beginning of modern Korean. Phonological, lexical, and grammatical characteristics of modern day Korean began to appear during this period of time. Phonologically, the 10 vowel system was established, glottal sounds and aspirated sounds increased, vowel harmony declined. Phenomena such as vowel raising, front-vowelization, monophthongization, and the word-initial rule appeared. Meanwhile, hangul-Chinese mix writing became common practice, and hangul-only writing also started to take place in narrative writing, and elements of spoken language began to reflect in written language. All those pointed to the unification of written and spoken language. Under the influence of modernization, a great amount of new words appeared. Especially, Japanese and other foreign words flooded in in great quantities. Grammatically, '-eos-(-엇-), -neun-(-는-), -ges-(-겟-)' trichotomy system of tenses was established, and hearer-oriented honorific system also formed a binary system of 'hasoseo(하소서), hasibsio(하십시오), hao(하오), hage(하게), haera(해라)' and 'hae (해), haeyo(해요)'. In word formation and sentence construction, the use of '-gi(-기)' became more frequent than '-eum(-음)', while '~geot(~것)' also significantly increased. In negative, causative and passive expressions, the use of long form, which has fewer restrictions than the short form, became more frequent. A tendency towards simplicity appeared. In the same vain, long and complex sentences with several clauses tend to be avoided. Instead, short simple sentences became more favorable. Korean linguistics scholars should pay closer attention to the modernization period, which includes the early 20th century. In order to fully understand today's Korean language, more thorough research on this immediately preceding period is necessary.

Phonological, morphological and molecular characteristics of Spatoglossum pacificum Yendo are examined. S. pacificum has an annual life cycle composed of saprophytes with apparent absence of male and female gametophytes in Korea. The seasonal growth of this species explains that the annual growth is closely related to the monthly variation of water temperature. S. pacificum has protruding reproductive structures above the outmost cortical layer. Although this observation is restricted to several species, reproductive structures on the thallus can make S. pacificurn distinguishable from S. crassum and S. lacturn. The morphogenesis of a midrib at the base of S. pacificum in this study is the same as those of Dictyopteris but different from those of S. crassum and S. lacturn, suggesting that S. pacificum is closely related to Dictyopteris. In the comparison of plastid gene sequences among species of Spatoglossum and Dictyopteris, S. pacificum is more similar to D. divaricata and D. undulate than those of S. crassum in rbcL, rbcS, psbA and psaA. This result is congruent with the anatomical characteristic of a midrib at the base of the thallus and the protrusion of reproductive organs on the thallus. The phylogenetic relationship based on these plastid genes also shows that S. pacifism is included in Dictyotpteris Glade and separated from S. crassum. We propose the new combination of Dictyopteris pacifica (Yendo) I.K. Hwang, H.S. Kim et W.J. Lee, comb. nov. based on the differences of anatomical characteristics of the midrib, the existence of reproductive organs on thallus and the molecular analyses.

Objectives : Mild Alzheimer's disease(AD) is uncertain to be related to visuospatial working memory subsystem dysfunction. We used the self ordered pointing test(SOPT) to find the characteristics of visuospatial working memory in mild AD. Methods : We compared the visuospatial working memory abilities of 20 patients with mild AD and 20 normal elderly controls(NC) using SOPT, of which stimuli consisted of two stimuli types(A : abstract, C : concrete) and two stimuli numbers(8 and 12). Therefore, working memory was tested using C8, C12, A8, and A12 stimuli conditions in SOPT. Mixed-model ANOVA was conducted with the AD and NC groups as between-subjects factor, with stimuli types and stimuli numbers as the within-subjects factors and with SOPT error rates as the dependent variable. Results : The AD group showed higher error rates in SOPT than the NC group. The NC group showed low error rates in concrete stimuli than in abstract stimuli and in small stimuli numbers than in large stimuli numbers. And the AD group showed no differences between stimuli types or stimuli numbers. Conclusion : AD patients showed a poor performance in visuospatial working memory using concrete stimuli. The result suggests that there is a non-transformation from visual input to phonological working memory in AD. Patients with AD showed a poor performance although in small stimuli number condition of SOPT. It suggests that in AD, visuospatial working memory is not working well although in low central executive loads.
