Jae-Il Yeom. 2018. Embedded Declaratives in Korean. Language and Information, 22.1, 1 -27. This paper deals with three verbs that take a declarative clause. The verb al ‘know’ takes a ko-phrase, which is non-factive, and a kes-phrase, which describes a fact. The verb mit ‘believe’ also takes both, but a kes-phrase taken by the verb denotes a proposition. The verb sayngkakha ‘think’ takes a ko-phrase, but not a kes-phrase. I claim that a ko-phrase is a predicate which reflects what is in the mind of the subject. A kes-phrase expresses something that exists independently of the epistemic process. It can be a fact or a proposition that is given. If a kes-phrase is selected by al, it denotes a fact and if a kes-phrase is selected by mit, it denotes a proposition. sayngkakha only expresses an epistemic state, and it does not take a kes-phrase. I also discuss an adnominal declarative clause as part of a kes-phrase.

김일룡,김재영,박종태,최재욱,김해준,염용태 대한산업의학회 2001 대한직업환경의학회지 Vol.13 No.3

목적 : 이 연구는 자동차 조립라인 근로자들의 사회·심리적 스트레스와 작업관련 근골격계 자각증상간의 연관성을 확인하는 데에 있다. 방법 : 경인지역 소재 자동차 회사 두곳의 조립라인에 근무하는 근로자 636명을 대상으로 하여, 근골격계 자각증상에 대해서는 목과 어깨, 팔과 팔꿈치,. 손목과 손, 허리부위에서의 통증, 쑤심, 뻣뻣함, 화끈거림, 무감각 또는 저림 등을 묻는 표준화된 설문지로 질문하였고, 스트레스 정도는 4개 분야, 45개 항목으로 이루어진 Psychosocial Well-being Index 설문지를 배포후 3점 척도를 적용하였다. 이들간에는 카이자승법, ANOVA rm리고 로짓회귀분석을 사용하여 통계적으로 유의한 연관성을 알고자 하였다. 결과 : 1. 수면시간을 제외하고 연령, 근속기간, 결혼여부, 학력수준, 흡연력, 음주력에 따른 상지근골격계 증상의 빈도 차이는 없었다. 2. 30세 미만의 작업자군에서 사회 심리적 스트레스 점수(p-value: 0.0461)와 스트레스 Factor 3 (p-value: 0.0368), Factor 4 (p-value: 0.0053)의 점수가 높았다. 3. 11∼15년의 근속기간을 가진 작업자의 경우 Factor 1을 제외한 PWI(p-value: 0.0001), Factor 2(p-value:0.0001), Factor 3(p-value: 0.0004), Factor 4(p-value: 0.0001)에서 기타의 근속기간을 갖는 동료에 비해 높은 스트레스 점수를 보였다. 4. 미혼자는 Factor 4에서 기혼자보다 높은 스트레스 점수를 보였다(p-value: 0.0068). 5. 수면시간이 6시간 이하인 작업자군은 6시간을 초과하는 작업자보다 PWI(p-value: 0.0087), Factor 2(p-value: 0.0194), Factor 3(p-value: 0.0048), Factor 4(p-value: 0.0314) 등에서 높은 스트레스 점수를 보였다. 6. 스트레스 점수는 정규분포를 이루었으며 정상군과 스트레스위험군간에 증상의 빈도 차이는 없었다. 7. 근골격계 증상이 있는 작업자군은 무증상군과 비교하여 기타 스트레스 점수는 두 군간에 유의한 차이가 없었으나, Factor 2에서 통계적으로 유의하게 높은 스트레스 점수를 보였고(p-value: 0.028), 단변량(OR: 1.02) 및 다변량(OR: 1.04) 로짓 회귀분석에서도 Factor 2가 양의 회귀계수(0.0226; 0.0352)를 보여 증상에 영향을 주는 것으로 나타났다. 결론 : 근골격계 자각 증상이 있는 조립작업자군은 증상이 없는 군에 비해 우울증 항목에서 높은 스트레스 점수를 보였으나 기타 사회적 역할 수행 및 자기신뢰도, 수면장애 및 불안, 일반건강 및 생명력등의 사회심리적 스트레스 항목에서는 두 군간에 유의한 차이를 보이지 않았다. 로짓회귀분석예서도 우울증이 근골격계 증상에 영향을 주는 것으로 나타나서 비록 제한적이지만 우울증에 해당하는 항목인 Factor 2와 증상간의 연관성을 일부 확인할 수 있었다. 그러나 근골격계 증상발현에는 스트레스 이외에도 인간공학적 혹은 알려지지 않은 요인들 중요하게 작용하므로 이들을 통제한 후의 추가적인 조사를 해야 할 것으로 생각된다. Objectives : To determine the relationship between stress Factors and work-related muscul-loskeletal symptoms of assembly line workers in the automobile industry. Methods : A cross-sectional study was conducted in two Factories of automobile manufacturing companies where inappropriate posture and repetitive motions were required. The total number of subjects was 636, and consisted entirely of men. The Age, length of work duration, marital status, education level, smoking status, drinking status, sleeping time and stress scores were investigated according to subgroups of general characteristics. We divided the subjects into a Reference group and a Stress risk group to compare the frequency of the variables between them. The stress scores of the Positive symptom group were compared with the Symptom free group by the t-test. To measure the stress level, the PWI(Psychosocial Well being Index) which consists of 4 Factors, totaling 45 items, was used. A standardized self-reported questionnaire was used to assess the symptoms in workers. The criteria for positive symptoms were based on Operational Definition of Work-related Musculoskeletal Disorders of the NIOSH. Results : 1) The subgroups of Age, Work duration, Marital status, Education level, Smoking status, Drinking status and Sleeping time revealed no differences in frequencies in musculoskeletal symptoms. 2) Higher PWI(p<0.05), Factor 3(p>0.05) and Factor 4(p<0.01) scores were observed in younger workers compared with older workers. 3) The workers who had work durations betwen 11-15 years showed higher PWI(p<0.01), Factor 2(p<0.01), Factor 3(p<0.01), and Factor 4(p<0.01), compared with other work duration subgroups. 4) Singles had higher Factor 4 scores(p<0.01). 5) The sleeping time of less than 6 hours a day expressed a higher PWI(p<0.01), Factor 2(p<0.05), and Factor 3(p<0.01), Factor 4(p<0.05). 6) There was no difference in the prevalence of musculoskeletal symptoms between the Reference group and Stress risk group. 7) The subjects who had Positive musculoskeletal symptoms showed a significant difference in Factor 2 scores compared with the Symptom free groups. 8) According to a univariate logistic regression analysis, Factor 2(OR: 1.02, 95% CI:1.00-1.04, p-value: 0.0291) expressed significant but mild effects on the musculoskeletal symptoms and a multivariate logistic regression showed a statistically significant effect on musculoskeletal symptoms(OR:1.04, 95% CI: 1.01-1.07, p-value: 0.0170). Conclusion : Psychosocial stress scores were not higher in symptomatic subjects compared with those who had no symptoms. Sleeping longer showed a protective effect on symptoms but this was not statistically significant. There was no relationship between the stress scores and musculoskeletal symptoms in social performance and self-confidence, general well-being and vitality. Factor 2(Depression) was statistically significant though its effect was mild. Limited to this study, We could find partial relationship between psychosocial stress(Depression) and musculoskeletal symptoms. So it could therefore be suspected that ergonomic or other unknown factors may be more significant causes of musculoskeletal symptoms but we did not investigate these.

Semantics for Specific Indefinites

Yeom, Jae-Il Korean Society for Language and Information 1997 언어와 정보 Vol.1 No.1

There has been no nuanimous analysis of specific indefinites. It is still disputed even whether specificity is a matter of semantics of pragmatics. In this paper, I introduce some properties of specific indefinites, and explain them based on the meaning of specificity. Specificity intuitively means that the speaker or someone else in the context has some individual in mind, which is generally accepted among liguistics. The main issue is how to represent the meaning of 'have-in-mind'. I review some philosophical discusstions of cognitive contact and show that when the use of an expression involves 'have-in-mind', the expression is rigid designator in the belief of the agent who has an individual in mind. in the use of a specific indefinite, this applies only to the information state of the agent of 'have-in-mind'. To represent this asymmetry, I propose a new theory of dynamic semantics, in which a common ground consists of multiple information states, as many as the number of the participants in a conversation. Moreover, each information state is structured as a set of epistemic alternatives, which is a set of possible information states of a participant in the context. Based on this semantics, the properties of specific indefinites are explained.

The Semantics of the English Progressive and the Imperfective Paradox

( Jae-il Yeom ) 한국언어정보학회 2003 언어와 정보 Vol.7 No.2

The progressive in English is taken to be an operator which takes a non-stative predicate and returns a predicate which denotes a process with a temporal frame around some definite time or event. When, it is combined with a predicate which has a culmination in the event, the sentence means that the culmination has not come yet. So the event denoted by the base predicate is not true at the current time. On the other hand, when it is combined with a predicate which has no culmination in the event, the event denoted by the base predicate is taken to be true. In this paper, this is explained by the semantics of the progressive based on the notion of contributiveness. I propose that a progressive sentence is verified by some subevents which are contributive to the current situation and the progress of the event beyond the threshold level of the event denoted by the base predicate. A sub-situation is contributive if the addition of it to the previous situation is more likely to lead to the whole situation than the previous situation. (Hongik University)

On Presupposition Projection

Yeom, Jae-Il The Korean Association for the Study of English La 2003 영어학 Vol.3 No.1

In this paper, I will review two main theories on presupposition projection and point out their problems, and suggest the directions of a better analysis. Satisfaction theory is based on the single idea that presuppositions must be satisfied in the local context for the interpretation of a sentence. Problems occur because the theory makes only a minimal requirement on the input context for interpretation. They include the problems of weak presuppositions, unmotivated local accommodation, and projection of satisfied presuppositions. Binding theory assumes that presuppositions are anaphoric elements which can be accommodated. I will show that the syntactic notion of binding is not motivated, and claim that presupposition projection is a matter of information. Finally, I suggest the directions for a better analysis.

Semantics for Default Rules

Yeom, Jae-Il Korean Society for Language and Information 2000 언어와 정보 Vol.4 No.2

It is well-known that default rules require a nonmonotonic logic. Veltman proposed one dynamic theory which interprets default rules in such a way that correct inferences can be made at each information state. But his theory has some problems. First, this theory excludes the possibility that a default rule can be true of false. Second, his representation of an information state makes it difficult to interpret a default rule embedded in another sentence. Third, the notion of a frame which is introduced in the interpretation of a default rule and the adjustment of inferential expectation has a more complex structure than is necessary, In this paper, I propose a truth-conditional theory of default rules in which the meaning of a default rule is defined as a truth-condition in a possible world and which assumes a simpler structure of a frame. This makes it possible to interpret a default rule embedded in a sentence. A dynamic theory for default rules is also proposed for correct inferences based on default rules.

Comparison of Two Conditional Connectives-(u)myen and -ta/La-myen in Korean

( Jae Il Yeom ) 한국언어정보학회 2004 언어와 정보 Vol.8 No.1

In this paper, I will look at two conditional connectives in Korean and point out differences between -(u)myen and -ta/la-myen in their distributions and semantics. One of the differences is that -ta/la-myen always allows epistemic interpretation, whereas -(u)myen allows epistemic interpretation only when the event time of the antecedent clause is in the past or present. A second difference is that only -(u)myen is used in purely temporal and habitual conditionals. A third difference is that the modality marker -keyss, which can have volitional or predictive interpretation with -(u)myen, cannot have predictive interpretation with -ta/la-myen. I propose that -ta/la-myen has the operator of settledness, which is defined with respect to the speech time, and explain the differences listed based on the semantics of settledness.
