        Velar palatalization-revisited

        Joo-Kyeong Lee 한국음운론학회 2000 음성·음운·형태론 연구 Vol.6 No.2

        Lee, Joo-Kyeong. 2000. Velar palatalization-revisited. Studies in Phonetics. Phonology and Morphlogy 6.2, 415-430. In this paper, I present a substantial phonetic basis for various patterns of velar palatalization, focusing on articulatory and perceptual roles. I argue that velar palatalization in phonology fundamentally arises from phonetic coarticulation between a velar consonant and a palatal vocoid and that the various patterns are appropriately characterized in terms of different degrees of coarticulation; greater coarticulation gives rise to a greater extent of modification of the velar constriction, resulting in a greater constrictional movement toward the palatal region. Moreover, a listener's perceptual factors also play a prominent role in determining some patterns; the patterns which are not predicted by the coarticulatory mechanisms may be attributed to the listener's misperception. This suggests that phonological patterns and processes can be satisfactorily explained when we consider phonetic details underlying sound production and perception. (Korea University)

        Han, Hye-seung, and Joo-Kyeong Lee. 2009. Prosodic features in the English phrases including particles, adverbial prepositions and prepositions. Studies in Phonetics, Phonology and Morphology 15.3. 499-514. This study attempts to investigate prosodic features in the English phrases including particles, (e. g., the second element in a verb phrase such as give up the exam), adverbial prepositions (e. g., the second element of jump off the wall) and prepositions (e.g., the second element of study in the room). A phonetic experiment was conducted to see if there are any differences and /or prosodic structures among those three phrases. The stimuli were varied with two different objects, noun and pronoun and two kinds of rate, slow and fast, and pitch accent distribution and phrasing were measured within the phrases. Results showed that pitch accents were very frequently realized on both the particles and the adverbial prepositions, but that prepositions were rarely implemented a pitch accent. When the objects were a pronoun, a pitch accent consistently moved to particles, adverbial prepositions, and prepositions. Moreover, there are more phrase involved in the boundaries of the particle + the following noun phrase and the preceding verb + adverbial preposition and the adverbial preposition + the following noun phrase. It was interpreted as stating that such patterns reflect the differences in semantic weight among the three elements and the degree of semantic cohesion with the preceding verbs and the following noun phrases, and that adverbial phrases show distinct prosodic features from both particles and prepositions. This suggests that adverbial prepositions should constitute their own category semantically and/or prosaically. (University of Seoul)

        This is a study to modify the curriculum of the ocean civil engineering department in junior college. We collected and analyzed data which are concerned on the curriculum development or improvement, the marine techniques and the ocean policy. And then we also gathered the opinions of the professors serving at the ocean civil engineering department by holding several conferences and investigated the opinions of the ocean civil engineers serving at the industrial organization by way of the inquring papers. In addition we collected the advices of educational specialists and ocean civil specialists by visiting personally. On the basis of above opinions we developed the jobs of graduates and made a model curriculum shown in Table 6. We tried to intensify the subjects of special basic field related to the ocean & civil engineering and the subjects of basic experiment & practise. The ocean observation practise was newly formed and the E. D. P.S was reinforced.

      • 영어 복합명사와 명사구의 강세충돌과 강세전이

        이주경,강선미 한국음성과학회 2004 음성과학 Vol.11 No.3

        Metrical Phonology has asserted that stress shift does not occur in English compounds because it violates the Continuous Column Constraint. Noun phrases, on the other hand, freely allow for stress shift, whereby the preceding stress moves forward to the preceding heavy syllable. This paper hypothesizes that stress does not shift in compounds as opposed to noun phrases and compares their pitch accentual patterns in a phonetic experiment. More specifically, we examined two-word combinations, noun phrases and compounds, whose boundaries involve stress dash and assured that the preceding words involve a heavy syllable ahead of the stress to guarantee the place for a shifting stress. Depending on where the preceding pitch accent is aligned, stress shift is determined. Results show that stress shift occurs in approximately 47% of the noun phrases and 59% of the compounds; therefore, the hypothesis is not borne out. This suggests that the surface representations derived by phonological rules may not be implemented in real utterance but that phonetic forms may be determined by the phonetic constraints directly operating on human speech.

        The authors in this manuscript aimed to provide a practical importance of the differential diagnosis of intracranial brain tumor with emphasis on non-neoplastic abnormalities such as cytotoxic edema of the penumbra zone in strokes. The well known SOLs are cerebral ischemic, inflammatory and dysplastic lesions, which intraaxially imitate glioma and other neurogenic tumors. Brain tumor is the one of common intracranial space-occupying lesions (SOLs) on the diagnostic images. However, many non-neoplastic lesions may be indistinguishable from tumors. Especially, early mortality used to be caused by space-occupying hyperacute ischemic stroke, brain edema and herniations. For the retrospective analysis, the authors reviewed the patient charts, the emergency brain Computerized Tomography (CT), magnetic resonance imaging (MRI), clinical stroke history. From Jan. 2003 to Dec. 2003, we managed total 61 acute strokes in ICU. Even though we operated six decompressive craniotomies, nine stereotactic craniotomies including two procedures of brain biopsy and three extraventricular drainage procedures, three patients (4.91%) were finally expired out from the induced herniation and medullary failure by those aggressive strokes. 43 patients (70.5%) were recovered good from stroke attack. 15 patients (24.6%) were improved with residual neurologic deficits. In conclusion, aside from growing efforts of the radiologist to make the early diagnostic impression, the authors suggest that urgent neurosurgical explorations with the pathologic diagnostic decision should be requested to decrease the fatality.

      • 몇 소나무類의 葉綠素 含量의 月別 變化

        李慶學,金甲泰,朱洸영,曺炅眞,李敦求 서울大學校 農科大學 1985 서울대농학연구지 Vol.10 No.2

        植物體는 生存 또는 生長을 위해 光合成作用을 하며, 綠色植物은 이를 위한 色素로서 葉綠體를 가지고 있다. 따라서 이의 含量은 生長能力이나 各種 stress에 대한 生理的 活成變化를 나타내는 指標로 이용되는데 이에 對한 硏究報告는 基礎的 資料로서의 重要性에도 불구하고 林木 특히 소나무類에 있어서는 극히 드물었다. 이에 서울大學交 農科大學 構內에 있는 소나무類 5樹種에 對한 針葉單位生重量當 葉綠素含量을 月別測定한 結果 樹種間의 含量差異는 뚜렷하니지 않았으나 測定時期間에는 差異를 보였다. 總葉綠素의 含量變化는 葉綠素 a의 含量變化에 起因하며 이는 여름철에는 높고 겨울철에는 낮았다. 또한 最大値는 2年生 針葉을 7, 8月에 測定했을 때 나타났다. 이러한 結果를 綜合해 볼 때 소나무類의 生理的 生活은 葉綠素 a와 密接한 關係를 갖고 있는 것으로 思料된다. To obtain the fundamental data about the chlorophyll contents of some conifers, monthly measurements of them per unit fresh weight(g) of needles were performed. The results were summarized as follows. 1. Difference of total chlorophyll contents between measuring times in a species was clear but not between species. Total chlorophyll content in summer showed high value and that in winter did low value. 2. In general, the total chlorophyll contents of the conifers showed the highest values in two-year-old needles, measured in July or August. 3. Monthly change of total chlorophyll contents was mainly due to that of the contents of chlorophyll a, and the contents of chlorophyll b was not varied greatly with measuring times. 4. It seems that the physiological activity of needles was closely related with the contents of chlorophyll a.

        우리나라 산재보험의 정신질환 인정실태

        최경숙,이현주,김세진,이창화 大韓神經精神醫學會 2006 신경정신의학 Vol.45 No.3

        Objectives : The purpose of this study was to determine characteristics of work-related psychiatric injuries with Korean Workers' compensation data. Methods : We analyzed the distribution of sex, age, types of work-related psychiatric disorders, type of industry and occupation. Using the data of 3175 Korean workers' compensation cases who were compensated for work-related psychiatric injuries from 2001 to 2003. Results : Work-related psychiatric injuries have increased annually. 897 cases, 1099 cases and 1179 cases were compensated during three years (2001-2003). Men accounted for many more cases than women. The most common age group was 41 -49. The majority of work-related psychiatric injuries were 'organic, including symptomatic, mental disorders', 'neurotic, stress-related and somatoform disorders' and 'mood [affective] disorders'. For accidental psychiatric injury cases construction and manufacturing were the most common industries. Manufacturing, business activities, construction and transport were common in regard to work-related psychiatric disorders. In this study there was a high frequency of craft and related trades workers, elementary occupations and plant and machine operators and assemblers in accidental psychiatric injury cases. Work-related psychiatric disorders were frequent for elementary occupations, plant and machine operators and assemblers, craft and related trades workers, service workers, legislators, senior officials and managers. Conclusion : This investigation provided more information about the psychiatric injuries of Korean workers. These findings should help formulate intervention and prevention strategies of work-related psychiatric disorders.
