Two fundamental aspects of speech summary generation are the extraction of key speech content and the style of presentation of the extracted speech synopses. We first investigated whether acoustic features (speaking rate, pitch pattern, and intensity) are equally important and, if not, which one can be effectively modeled to compute the significance of segments for lecture summarization. As a result, we found that the intensity (that is, difference between max DB and min DB) is the most efficient factor for speech summarization. We evaluated the intensity-based method of using the difference between max-DB and min-DB by comparing it to the keyword-based method in terms of which method produces better speech summaries and of how similar weight values assigned to segments by two methods are. Then, we investigated the way to present speech summaries to the viewers. As such, for speech summarization, we suggested how to extract key segments from a speech video efficiently using acoustic features and then present the extracted segments to the viewers.

The purpose of this study was to conduct a dynamic analysis of married women's return to the workforce following first childbirth. We have based our investigation on the data compiled by the KLIPS, where the workforce performance is the focal point of it's research, and by these materials, this study has analyzed the aspects of the factors that decide post-childbirth return to the workforce. We have applied the Cox Regression Hazard Model, where corroborative evidence are statistically applied. The following are the conclusions that were derived from this research: First, according to the study, academic background is a vital factor in reducing the gap and time of women's return to the workforce. Second, whether having active child-care after giving birth or not doubles the chances of women returning to the workforce. Third, if the pre-birth employment form was a wage-work and the rate of returning to the workforce was lower than the non-wage, relatively speaking, this reflects that the non-wage form of work, which provides a better possibility to return to the workforce after giving birth, could be another way to prevent women's career discontinuation.

The first, this study analyzed empirically the effects of net profit on sales, total asset turnover and debt ratio on return on equity, the second, verified debt' s mediating effect on return on investment and return on equity and finally, tested the effect of adjusted debt ratio on return on equity in the small medium sized enterprises. Generally speaking, using debt has a positive effect on return on equity. Meanwhile, using debt accelerate return on equity through leverage effect in the quadric function curve model. Eventually, using debt has a positive and negative effects on return on equity. Accordingly, because of the debt' janus-faced reality, using debt is restricted within the level that operating cash flow(or return on asset) excess interest(or rate of interest).

This study was performed to investigate the clinical pictures and rehabilitation service patterns of stroke patients in cities of kimchon(kumi), jinju. pohwang, jeonju and jeju from January 1,2001 to march. Authors developed structured questionnaire, and distributed it to each physical therapist. Total number of distributed questionnaire was 400, and 301 questionnaire were col looted and analysed finally.1. The occurrence rate of hemorrhagic stroke(60.5%) was higher than that of ischemic stroke(39.5%). The highest incidence of the stroke was noted in the group of 50 years and ratio of male to female 1.3 : 1. 2. The several warning sign is motor deficit(42.5%). headache. dizziness, vomitting(31.9%) and difficulty speaking or understanding(10.6%). 3. The most important contributing factor of stroke was hypertension both hemorrhagic(50.0%) and ischemic stroke(40.3%). 4. In the painful stroke patients(53.2%). the major problems were shoulder pain(51.3%) and shoulder-hand syndrom(31.3%). 5. In hemorrhagic stroke. the seasonal preference was autumn and summer. In ischemic stroke. the seasonal preference was autumn and winter. 6. In the surgery, hemorrhgic stroke(44.5%) was higher than that of ischemic stroke(20.2%). 7 The major impairment were motor deficit(95.3%), psychological deficits(24.4%), hearing and speech deficit(23.4%). vision deficit(14.7%) and perception deficit(12.7%). 8. The rehabilitation services for stroke patients were physical therapy(98.0%), occupational therapy(41.5%), oriental therapy(35.1%), speech therapy(17.5%) and psychological therapy(7.4%). 9. The start of rehabilitation service was different according to surgery. 36.5% of patients started physical therapy in 4 week and 32.0% of patients started in 8 week later in surgery and 53.1% of patients started physical therapy in 2 week in not surgery( P<0.05). 10. The highest frequency of rehabilitation service was six times per week.

In this paper, we implement an AAC(Augmentative and Alternative Communication) system based on image dictionary in order that speech defectives can easily communicate their opinion to others by using images. Normally, those who have a speech defect use only a few limited words to express their intentions and it is an effective way to use images in their communication because they have a difficulty in speaking. Therefore we make verbal images of verb and adjective that play an important role in expressing the speaker's intention, define pattern of semantic relation between the verbal images and noun images, and construct the image dictionary. In this AAC system, when a user clicks a verbal image, the system generates a sentence by selecting noun images which are component parts of corresponding pattern based on semantic relation with the verbal image. We evaluate the implemented system by how efficiently children of speech defect can express their intention and the result shows more than 70% of success rate in communication.

This study was conducted with 512 students in 4 primary schools located at the inner and the outskirt of K city, Northern Kyungsang Province from November 6, 2001 to November 27, 2001(during 3 weeks). This study was a research about the difference of a bullying degree and tendency of both teasing and teased students. The purpose of the study was to help nursing teachers in charge of student consultation and treatment. The findings are as follows: First, for to whom students confess their worries, students in lower grade talked to their parents while students in higher grade talked to their close friends. The higher grader, the higher rate in solving their problems by themselves. For how many students are teased by their peers in groups, 52.0％ students answered 1 or 2 students in a class. For the reasons of bully, 37.0％ higher graders answered, very selfish and putting on airs after 29.6％ lower graders answered, ugly and bad at speaking. Second, for perception of peer relation, 81.3％ students participating in the study answered, very important. For a question whether students satisfy present relation with their friends by gender, 53.7％ boys were satisfied while 34.6％ girls were satisfied. Third, for difference in bullying by gender, boys mainly teased others by using words and physical power(p<0.000) while girls estranged others. When it goes to teased students, it was the case: boys were bullied physically(p<0.000) and linguistically while girls were hurt by estrangement. Having nothing direct to do with school achievement, nursing teacher should make good use of such an advantage that students tend to easily confess their worries to them and take care of psychological aspects of students in treatment. Furthermore, it needs to include contents of bully in the regular heath care education.

Objectives: This study investigated the association between oral health and suicide attempts in adults aged 65 years or older using the 7^th Korea National Health and Examination Survey (KHANES, 2016-2018). Methods: Of the total 24,269 participants of the 7^th KHANES (2016-2018), 1,488 adults aged 65 years or older who had an oral health examination were selected. Variations in suicide attempts with demographic characteristics and perceived oral health status were analyzed using the χ² test, and the association between oral health and suicide attempts was analyzed using the logistic regression model. Results: The suicide attempt rate was higher among older adults with chewing (p<0.01) and speaking (p<0.05) difficulties. The odds ratio for a suicide attempt was 1.05 times higher among those with tooth loss (p<0.05). Conclusions: Our results showed that older adults with tooth loss had an increased risk of suicide. Thus, it is important to prevent tooth loss, in the first place, through proper oral health management. If tooth loss occurs, appropriate treatment should be prioritized to facilitate functional recovery. Finally, national support is required for older adults with limited access to dental care.

The purpose of this study is to find the characteristics of organic matters based on the distribution and oxidation rates, as noted according to the spatial and temporal variations from 2008 to 2016. Generally speaking, the Han River system is separated into one lower course and two upper courses which are the Namhan River and Bukhan River. The seasonal factor is one of the most important causes of water quality changing in both of the upper courses as a result of a few pollution sources. The concentration of organic matter was measured as higher in the lower course into which great streams with point and non-point sources were identified. According to seasonal variations, however, the change of the organic matter in the lower course is comparatively slighter than that of organic matters in the upper courses. The oxidation rates related to the BOD were 15 %, 17 % and 26 % in the Bukhan River, Namhan River and the lower course, respectively. These results could be explained that more biodegradable organic matter were seen to have existed in the lower courses comparing to the activity in the upper course. The oxidation rates of the BOD were noted as relatively higher in the eutrophicated places with phytoplankton. Therefore the BOD is one of the good index models to find the characteristic of the eutrophicated water. On the other hand BOD would not be enough to estimate concentration of refractory organic matters in the Bukhan and Namhan river. Consequently, both of the TOC and BOD are necessary indices to understand the identified refractory and/or biodegradable characteristics of organic matter.

Background: As a result of the South Korean government's medical tourism strategies, the number of UAE inbound medical tourists have the highest annual increase rate among the Middle Eastern countries. The need for medical interpreters in such cases is inevitable, especially considering the languages spoken in both countries differs. The work of a medical interpreter affects patient satisfaction, quality of care, and the UAE patients' revisit intention. However, there is a lack of literature that focuses on the role of medical interpreters for the Arabic-speaking medical tourists in South Korea. The purpose of this study is to assess the satisfaction and the experience of UAE medical tourists in South Korea who have used medical interpretation services. Method: A descriptive exploratory design, including semi-structured interviews, was used in this study to examine factors influencing the satisfaction of UAE patients seeking medical attention in South Korea, who considered travelling exclusively for medical purposes. Eleven UAE medical tourists were selected for the interview using convenience sampling. Results: Two types of interpreters were revealed by the analysis: interpreters with Arabic as their mother tongue and interpreters with Korean as their mother tongue. Patients emphasized the origin of the interpreters and differentiated between the two types of interpreters' professionalism, abilities, and personal skills. However, due to the huge gap between the two cultures, languages, and religions, the UAE patients mainly preferred the Arabic medical interpreters. Further, each type had certain traits that impacted the medical care process and patients' satisfaction. Conclusion: This study shows that the South Korean government needs to focus on the training and assessment system for Arabic language interpreters. Additionally, cultural differences training for the interpreters may help to increase UEA patients' satisfaction.
