인간의 자연스러운 대화에서는 생략 현상이 빈번하게 일어난다. 생략 어구로부터 화자의 의도를 파악하는 것은 쉽지가 않다. 생략 어구 자체만 가지고는 그것의 의미와 화자의 의도를 파악하기 힘들며 이전 발화들로부터 구성된, 혹은 영역에 내재된 맥락과의 연관성을 살펴보아야 하기 때문이다. 본 연구에서는 Lambert가 제안한 3단계 계획기반 대화이해모델을 확장함으로써 한국어 대화에서 나타나는 생략 어구로부터 화자의 의도를 인식하는 모델을 제안한다. 먼저 Lambert의 모델에서 고려하지 않은, 생략 어구 형태의 발화를 통해 화자가 의도하는 담화 행위를 새로운 담화 recipe로 정의하여 추가하였다. 한국어에서는 조사가 화자의 의도를 나타내므로 이러한 특성을 이용하여 생략어구를 표층 화행으로 표현할 때, 조사 정보를 포함하여 화자의 의도 인식을 용이하게 함을 볼 수 있었다. 또한 객체와 초점화 이론을 제안하여, 생략 어구를 통해서 화자가 두 개의 계획을 비교하여 고려하는 의도를 인식할 수 있도록 했다.

The tendency of the Minimalism in the contemporary a architecture is based on Mies van der Rohe s saying ‘나SS IS m more" as the principle of the Minimal art and its formative c composition. It can be divided into technical Minimalism p prevailed in Northern Europe and the zone of German l language, and the regional one in Southern Europe and S Southern America. The former is interested in the experiences of the techniques and materials, and the latter in that of the s space and the place through the simple forms. The minialistic approach to the architecture is nat only m methodological one. It accepts the concept and the construction of architecture as 2 axes for making it keeps the tradition and c communication with the master builder, the materials, and i염 m means to compound. The expressive characteristics of works in M Minimalism are 1) as the formal issue, it is simple, self-referring. without any symbol or any allusion, and compounds the r repetitive forms as the comceptual aspec않 of architecture, 2) it h has the characteristies such as the approach directly to the m means by which architecture made, the critical interests to the m material attributes, and the capacity to the contemporary t technology as the issue of technique and materials, 3) regarding t the space and the place, it shows the good sense to the site in t the sphere intervention of architecture 1e Maininlalism architecture has i않 impotance in the point t that it seeks to the qualities immanent in architecture by s showing the marvelous status through discovering the i immanent properties of the site, program materials, and the s structure, and also it begins new way of interpreting a architecture with new viewpoint to the its essence as well as a architecture itself.self.

Studying the structural behavior of prestressed segmented girders is quite important due to the large use this type of solution in viaducts and bridges. Thus, this work presents a nonlinear three-dimensional structural analysis of an externally prestressed segmented concrete girder through the Finite Element Method (FEM), using a customized ANSYS platform, version 14.5. Aiming the minimization of the computational effort by using the lowest number of finite elements, a new viscoelastoplastic material model has been implemented for the structural concrete with the UPF customization tool of ANSYS, adding new subroutines, written in FORTRAN programming language, to the main program. This model takes into consideration the cracking of concrete in its formulation, being based on fib Model Code 2010, which uses Ottosen rupture surface as the rupture criterion. By implementing this new material model, it was possible to use the three-dimensional 20-node quadratic element SOLID186 to model the concrete. Upon validation of the model, an externally prestressed segmented box concrete girder that was originally lab tested by Aparicio et al. (2002) has been computationally simulated. In the discretization of the structure, in addition to element SOLID186 for the concrete, unidimensional element LINK180 has been used to model the prestressing tendons, as well as contact elements CONTA174 and TARGE170 to simulate the dry joints along the segmented girder. Stresses in the concrete and in the prestressing tendons are assessed, as well as joint openings and load versus deflection diagrams. A comparison between numerical and experimental data is also presented, showing a good agreement.

Objectives: An attempt was made to understand the nicotine dependence of smokers selected for an ongoing smoking cessation intervention programme in rural Kerala, India. Methods: Data were collected from resident males in the age group of 18 to 60 years from 4 randomly allocated community development blocks of rural Thiruvananthapuram district (2 intervention and 2 control groups). Trained accredited social health activist workers were utilised to collect data from all groups through face to face interview. Nicotine dependence among participants was assessed by means of the six-item Fagerstrom Test for Nicotine Dependence (FTND) translated into the local language. The internal consistency of FTND was computed using Cronbach's alpha coefficient. Criterion validity (concurrent) was assessed by correlations of nicotine dependence scores with age at initiation of smoking and cumulative smoking volume in pack-years. Results: Among the 928 smokers identified, 474 subjects were in the intervention area (mean age = 44.6 years, SD = 9.66 years) and 454 in the control area (mean age = 44.5 years, SD = 10.30 years). The overall FTND score among current daily smokers was 5.04 (SD: 5.05). FTND scores in the control and intervention areas were 4.75 (SD: 2.57) and 4.92 (SD: 2.51) respectively. The FTND scores increased with age and decreased with higher literacy and socioeconomic status. The average FTND score was high among smokers using both bidi and cigarettes (mean 6.10, SD 2.17). Internal consistency analysis yielded a Cronbach's alpha coefficient of 0.70 in a subsample of 150 subjects, a moderate result. The association of the scale was strongest, with the number of pack-years smoked (rho = 0.677, p < 0.001). Conclusion: A moderate level of nicotine dependence was observed among smokers in the current study. Tobacco cessation strategies could be made more cost effective and productive if a baseline assessment of nicotine dependence is completed before any intervention.

본 논문은 고음질의 대용량 코퍼스 기반 음성 합성기에 감정 음성 코퍼스를 추가하여 보다 다양한 합성음을 생성할 수 있는 방법에 관한 것이다. 파형 접합형 합성기에서 사용할 수 있는 형태로 감정 음성 코퍼스를 구축하여 기존의 일반 음성 코퍼스와 동일한 합성단위 선택과정을 통해 합성음을 생성할 수 있도록 구현하였다. 감정 음성 합성을 위해 태그를 사용하여 텍스트를 입력하고, 억양구 단위로 일치하는 데이터가 존재하는 경우 감정 음성으로 합성하고, 그렇지 않은 경우 일반 음성으로 합성하도록 하였다. 그리고 음성에서 운율을 구성하는 요소로 휴지기(break)가 있는데, 감정 음성의 휴지기는 일반 음성보다 불규칙한 특성이 있다. 따라서 합성기에서 생성되는 휴지기 정보를 감정 음성 합성에 그대로 사용하는 것이 어려워진다. 이 문제를 해결하기 위해 가변 휴지기(Variable break)[3] 모델링을 적용하였다. 실험은 일본어 합성기를 사용하였고, 그 결과 일반 음성의 휴지기 예측 모듈을 그대로 사용하면서 자연스러운 감정 합성음을 얻을 수 있었다.

Spontaneous intracerebral hemorrhage (sICH) has a high mortality rate. Research has demonstrated that sICH occurrence is related to weather conditions; therefore, this study used the decision tree method to explore the impact of climatic risk factors on sICH at different ages. The Taiwan National Health Insurance Research Database (NHIRD) and other open-access data were used in this study. The inclusion criterion was a first-attack sICH. The decision tree algorithm and random forest were implemented in R programming language. We defined a high risk of sICH as more than the average number of cases daily, and the younger, middle-aged and older groups were calculated as having 0.77, 2.26 and 2.60 cases per day, respectively. In total, 22,684 sICH cases were included in this study; 3,102 patients were younger (<44 years, younger group), 9,089 were middle-aged (45-64 years, middle group), and 10,457 were older (>65 years, older group). The risk of sICH in the younger group was not correlated with temperature, wind speed or humidity. The middle group had two decision nodes: a higher risk if the maximum temperature was >$19^{\circ}C$ (probability = 63.7%), and if the maximum temperature was <$19^{\circ}C$ in addition to a wind speed <2.788 (m/s) (probability = 60.9%). The older group had a higher risk if the average temperature was >$23.933^{\circ}C$ (probability = 60.7%). This study demonstrated that the sICH incidence in the younger patients was not significantly correlated with weather factors; that in the middle-aged sICH patients was highly-correlated with the apparent temperature; and that in the older sICH patients was highly-correlated with the mean ambient temperature. "Warm" cold ambient temperatures resulted in a higher risk of sICH, especially in the older patients.

Breast cancer is the most common cancer among women worldwide. The primary aim of this work was to provide an in-depth evaluation of research publications in the field of diets and breast cancer. The impact of economic outcome on national academic productivity was also investigated. Data were retrieved using Pubmed for English-language publications. The search included all research for which articles included words relating to "diets and breast cancer". Population and national income data were obtained from publicly available databases. Impact factors for journals were obtained from Journal Citation Reports$^{(R)}$ (Thomson Scientific). There were 2,396 publications from 60 countries in 384 journals with an impact factor. Among them, 1,652 (68.94%) publications were Original articles. The United States had the highest quantity (51% of total) and highest of mean impact factor (8.852) for publication. Sweden had the highest productivity of publication when adjusted for number of population (6 publications per million population). Publications from the Asian nation increased from 5.3% in 2006 to 14.6% in 2012. The Original article type was also associated with geography (p<0.001; OR=2.183; 95%CI=1.526-3.123), Asian countries produced more proportion of Original articles (82%) than those of rest of the world (67.6%). Diets and breast cancer-associated research output continues to increase annually worldwide including publications from Asian countries. Although the United States produced the most publications, European nations per capita were higher in publication output.

Objective: This study investigates the impact of multimorbidity on work through a literature review of longitudinal studies. Methods: A systematic review was carried out in the databases Lilacs, SciELO, PAHO, PubMed/Medline, Scopus, Web of Science, and Cochrane. There were no restrictions regarding the year of publication or language to maximize the identification of relevant literature. The quality of studies was assessed by the protocol STrengthening the Reporting of OBservational studies in Epidemiology (STROBE). Results: An initial database search identified 7522 registries, and at the end of the analysis, 7 manuscripts were included in the review. Several studies have demonstrated direct and indirect impacts of multimorbidity on the health of workers. For this, the number of missed days due to health-related issues was evaluated, as well as the reduction in work productivity of the unhealthy worker, vulnerability of the worker with multimorbidity regarding higher indices of dismissal and recruitment difficulties, and incidence of early retirement and/or receipt of benefits due to disabilities. Conclusions: Multimorbidity has a negative impact on work, with damages to quality of life and work productivity, worsening the absenteeism/presenteeism indices, enhancing the chances of temporary or permanent leaves, and lowering employability and admission of individuals with multimorbidity.

The current study assessed the utility of acoustic analyses the most commonly used in routine clinical voice assessment including perturbation, nonlinear dynamic analysis, and Spectral/Cepstrum analysis based on signal typing of dysphonic voices and investigated their applicability of clinical acoustic analysis methods. A total of 70 dysphonic voice samples were classified with signal typing using narrowband spectrogram. Traditional parameters of %jitter, %shimmer, and signal-to-noise ratio were calculated for the signals using TF32 and correlation dimension(D2) of nonlinear dynamic parameter and spectral/cepstral measures including mean CPP, CPP_sd, CPPf0, CPPf0_sd, L/H ratio, and L/H ratio_sd were also calculated with ADSV(Analysis of Dysphonia in Speech and VoiceTM). Auditory perceptual analysis was performed by two blinded speech-language pathologists with GRBAS. The results showed that nearly periodic Type 1 signals were all functional dysphonia and Type 4 signals were comprised of neurogenic and organic voice disorders. Only Type 1 voice signals were reliable for perturbation analysis in this study. Significant signal typing-related differences were found in all acoustic and auditory-perceptual measures. SNR, CPP, L/H ratio values for Type 4 were significantly lower than those of other voice signals and significant higher %jitter, %shimmer were observed in Type 4 voice signals(p<.001). Additionally, with increase of signal type, D2 values significantly increased and more complex and nonlinear patterns were represented. Nevertheless, voice signals with highly noise component associated with breathiness were not able to obtain D2. In particular, CPP, was highly sensitive with voice quality 'G', 'R', 'B' than any other acoustic measures. Thus, Spectral and cepstral analyses may be applied for more severe dysphonic voices such as Type 4 signals and CPP can be more accurate and predictive acoustic marker in measuring voice quality and severity in dysphonia.
