Purpose: Some of the properties of the prosodic phrasing and some acoustic and phonological effects of contrastive focus on the tonal pattern of Seoul Korean is explored based on a brief experiment of analyzing the fundamental frequency(=FO) contour of the speech of the author. Data Base and Analysis Procedures: The examples were chosen to contain mostly nasal and liquid consonants, since it is difficult to track down the formants in stops and fricatives during their corresponding consonantal intervals and stops may yield an effect of unwanted increase in the FO value due to their burst into the following vowel. All examples were recorded three times and the spectrum of the most stable repetition was generated, from which the FO contour of each sentence was obtained, the peaks with a value higher than 250Hz being interpreted as a high tone (=H). The result is then discussed within the prosodic hierarchy framework of Selkirk (1986) and compared with the tonal pattern of the Northern Kyungsang dialect of Korean reported in Kenstowicz & Sohn (1996). Prosodic Phrasing: In N.K. Korean, H never appears both on the object and on the verb in a neutral sentence, which indicates the object and the verb form a single Phonological Phrase ($={\phi}$), given that there is only one pitch peak for each $={\phi}$. However, Seoul Korean shows that both the object and the verb have H of their own, indicating that they are not contained in one $={\phi}$. This violates the Optimality constraint of Wrap-XP (=Enclose a lexical head and its arguments in one $={\phi}$), while N.K. Korean obeys the constraint by grouping a VP in a single $={\phi}$. This asymmetry can be resolved through a constraint that favors the separate grouping of each lexical category and is ranked higher than Wrap-XP in Seoul Korean but vice versa in N.K. Korean; $Align-x^{lex}$ (=Align the left edge of a lexical category with that of a $={\phi}$). (1) nuna-ka manll-ll mEk-nIn-ta ('sister-NOM garlic-ACC eat-PRES-DECL') a.

Korean Focus and Phrasing: Two major effects of contrastive focus on phonological phrasing are found in Seoul Korean: (a) the peak of an Intonatioanl Phrase (=IP) falls on the focused element; and (b) focus has the effect of deleting all the following prosodic structures. A focused element always attracts the peak of IP, showing an increase of approximately 30Hz compared with the peak of a non-focused IP. When a subject is focused, no H appears either on the object or on the verb and a focused object is never followed by a verb with H. The post-focus deletion of prosodic boundaries is forced through the interaction of StressFocus (=If F is a focus and DF is its semantic domain, the highest prominence in DF will be within F) and Rightmost-IP (=The peak of an IP projects from the rightmost $={\phi}$). First Stress-F requires the peak of IP to fall on the focused element. Then to avoid violating Rightmost-IP, all the boundaries after the focused element should delete, minimizing the number of $={\phi}$'s intervening from the right edge of IP. (2) (omitted) Conclusion: In general, there seems to be no direct alignment constraints between the syntactically focused element and the edge of $={\phi}$ determined in phonology; all the alignment effects come from a single requirement that the peak of IP projects from the rightmost $={\phi}$ as proposed in Truckenbrodt (1995).

본 연구에서는 심혈관 질환의 위험 인자인 고혈압, 이상지질혈증 및 당뇨병이 없는 건강한 성인 남·녀를 대상으로 3축 가속도계를 이용하여 일주일간의 평소 신체활동량을 평가하고 동맥경화지표와의 연관성을 알아보고자 하였다. 가속도계를 이용한 신체활동 측정 결과, WHO 신체활동지침 준수율은 29.9%, 좌식 행동에 소비한 시간은 531.1 min/day, 저강도 활동에 소비한 시간은 281.4 min/day, 중·고강도 활동에 소비한 시간은 36.2 min/day 이였다. 활동 수준이 다른 두 군의 신체활동을 비교한 결과, CPM, 중·고강도 활동에 소비한 시간, 중·고강도 활동을 10분 이상 지속한 횟수 및 시간은 활동군이 비활동군에 비해 유의하게 높았다. 좌식 행동에 소비한 시간은 활동군이 비활동군에 비해 유의하게 낮은 반면 좌식 행동 패턴 및 baPWV와 ABI는 두 군 간에 유의한 차이가 없었다. 그러나 여자에서는 좌식 행동을 60분 이상 지속하는 횟수와 baPWV 간에 양의 상관관계가 나타났으며 좌식 행동을 50분 이상 지속하는 횟수와 ABI 간에 음의 상관관계를 보였고, 저강도 활동에 소비한 시간과 ABI 간에는 양의 상관관계를 보였다. 이는 좌식 행동을 50분 이상 지속하는 횟수가 많을수록 동맥경화 및 말초 동맥질환의 위험이 높고 저강도 활동에 소비한 시간이 많을수록 말초동맥질환의 위험이 낮음을 보여주었다. 향후 동맥경화 예방을 위한 지침 마련을 위해 다양한 연령대의 건강한 성인을 대상으로 신체활동과 함께 식품 및 영양섭취 현황, 식사 패턴, 음주 행태 등 동맥경화와 관련된 요인들이 포함된 연구의 필요성을 제안하는 바이다.
