The purpose of this paper is to extract the vowel formants of the ten young male speakers from the Buckeye Corpus of Conversational Speech [1] and to analyze them in comparison to earlier works in terms of various phonetic factors that are expected to affect the realization of the formant distribution. The first two formant frequency values were automatically extracted with a Praat script along with such factors as the place of articulation, the content versus function word information, syllabic stress information, the location in a word, location in utterance, speech rate of three consecutive words, and the word frequency in the corpus. The results indicated that the formant patterns from the corpus were very different from those of earlier works although the overall pattern was similar and that the factors were strongly responsible for the realization of the two formants.

Residential space has come to maintain a degree of specialization dependent upon the division of space according to function, while roles and functions have either expanded or ceased to exist corresponding to shifts in social values. However, various human behaviors connected to lifestyle habits and values are in fact becoming obsolete. This research will examine the mental, social, and functional aspects of the relationship between residential work spaces in modern homes and the sarangche as well as the communal space of daily and social life of the Chosun Dynasty to enhance the value and function of traditional residential space. As the boundary between family and work blurs with the home office environment of today, we are experiencing a deterioration of health and seeing problems in securing family domain as well as the prolonging of overwork. While the function of the traditional sarangchae encompassed a wider variety of activities than today's homes, the sarangchae achieved an efficient use of space divisions between rooms according to the particular purpose and situation. Accordingly, a reinterpretation of modern residential work space is needed through its connection to the sarangchae with consideration to the philosophy and values of the life of the noble class and the habits of our traditional lifestyle that have previously taken place within the sarangchae in an exterior space.

For last several decades, the color correction methods have been proposed for HDR(high dynamic range) images. However, color distortion problems take place after correcting the colors such as halos, dominant color as well known. Accordingly, this article presents a novel approach in which the method consists of tone-mapping method and cone response function. In the proposed method, the tone mapping method is used to improve the contrast in the given HDR image based on chromatic and achromatic based on the CIEXYZ tristimulus value, expressed in c/m². The cone response function is used to deal with mismatch between corrected image and displayed image as well as to estimate various human visual effects based on the CMCAT2000 color appearance model. The experimental results show that the proposed method yields better performance of color correction over the conventional method in subjective and quantitative quality, and color reproduction.

The attire of businesspersons has a significant impact on their social status and career. In accordance with the norms of the work place, the types of office attire are diversified. This research was conducted to determine the relationship between the work role of men and their attire, and how satisfaction with their work attire influences their job satisfaction. This study classifies work attire into three categories: uniform, suit, and freestyle. Data from 268 respondents were analyzed, and four work attire satisfaction factors were extracted: symbolic, quality, role function, and aesthetic factors. The group members wearing uniforms displayed a high level of satisfaction with regard to symbolism, role function, and quality; those wearing suits displayed a high level of satisfaction with regard to aesthetics; and those wearing freestyle displayed a high level of satisfaction with regard to role function and aesthetics. Overall, satisfaction with work attire was the highest in the freestyle group. For people wearing uniforms and suits, symbolism, quality, and aesthetics had a significant influence on overall satisfaction, whereas for those wearing freestyle, symbolism had a negative influence and quality had a positive influence on overall satisfaction. To conclude, work attire satisfaction had a greater effect on the job satisfaction of the men in uniforms and suits than on those wearing freestyle.

PURPOSE: The purpose of this study was to investigate the quality of life related to fall experiences in chronic stroke patients. METHODS: This cross-sectional study included 117 patients with stroke from 3 hospitals in D metropolitan city. General characteristics, including fall experiences and quality of life, were assessed through a face-to-face interviews conducted in a quiet place using a questionnaire. Measurement of quality of life in stroke patients was conducted using the Korean Stroke Specific Quality of Life Scale (SS-QOL). To identify the SS-QOL items related to fall experiences, the items of the SS-QOL were considered as independent variables, and the variables that were significantly different according to fall experiences were identified using a univariate analysis. A binary logistic regression was then performed using fall experiences as the independent variable. RESULTS: According to the univariate analysis, self help activities, social role, and upper extremity function were significantly lower in the fall group than that in the non-fall group (p<.05). The findings of the binary logistic regression confirmed that social roles and upper extremity function were the SS-QOL items that were related to fall experience in chronic stroke patients. CONCLUSION: These findings suggest that social roles and upper extremity function may be risk factors for fall experience in patients with chronic stroke.

Purpose: This study was performed to assess the degree of cognitive function of elderly by MMSE-K performances and of that effect. Method: The subjects were 185 aged over 65 in Daejeon Metropolitan city. Data were collected through personal interview using the questionnaire from 10 to 31, Jan. 2003. The measures were Korean version of Mini-Mental State Examination(MMSE-K). Results: The mean score of MMSE-K was $22.60{\pm}5.39$. The prevalence of cognitive impairment was estimated as 48.6% by MMSE-K ${\leq}23$ and significantly age, gender, and education effect. The subtype score of MMSE-K were significantly lower in female group in each items : orientation in time and place, attention/calculation, language except registration and recall. And the scores were significantly lower in the older group and non-educated group in the all items of MMSE-K. Conclusion: Gender, age, and education showed significant effects on total and subtype MMSE-K score. Cognitive function decline were higher in female, older age group, and non-educated group. Therefore, those three factors are thought to be one of important risk factors for development of dementia, also it is assumed to be affected by other variables than age, gender, education effect.

Korea, as a leader of Internet and game sector in IT industry, has been playing an important role in increasing its industrial development. This country has won the first place in wireless broadband usage and contributed to Internet game industry development. This means that Korean use smartphones most. It is juveniles that use Internet and smartphones most among Korean who use teenage., the number of the teenagers who overuse smartphones or Internet has surpassed 200,000. The number of the adolescents who spend more time using smartphone and Internet is about 180,000 and the number of the teens who are over-dependent to smartphone having trouble living their lives is over 22,000. The SNS usage rate of the contents that teens are most likely to use has accounted for over 80 percent. Among teens, SNS is being considered as a major means that builds relationship due to smartphone technology and the prevalence of smartphones. However, the use of SNS among youths has two sides; one is positive, the other negative. Not only does SNS have a positive function that it keeps relationship but it also has a negative function that it can lead to smartphone addiction.

This study was to measure whether single axis foot or the SACH foot applied to below-knee amputation patients would bring positive changes to the patients' cardiopulmonary function, and help them to overcome their disability. The experiment took place at Asan Medical Center, University of Ulsan, from July 20th to November 20th, 1999 with 10 below-knee amputation patients. The patients were asked to equip single axis foot and SACH foot by turns and lead them to walk on a treadmill which was designed to increase its steep slope. Patients heart rate and blood pressure were recorded before and after their walking, The heart rate, systolic blood pressure, diastolic blood pressure of the patients who were equipped with, either SACH foot or single axis foot, have been increased with as the slant becoming steeper. The heart rates during the experiment did not show relevant changes according to the kind of foot used and the gradient, but the changes occurred before and after the walking(p=0.0001), The similar result of systolic blood pressure was found during the waking(p=0.01). Below-knee amputation patients are expected to walk and perform the routines better, no matter what type of foot is used, as long as they wear an artificial foot properly and taking features of foot product into consideration

In facing the lack of a deterministic algorithm for economic load dispatch optimization problem, only non-deterministic heuristic algorithms have been suggested. Worse still, there is a near deficiency of research devoted to real-time load dispatch optimization algorithm. In this paper, therefore, I devise a shut-off and swap algorithm to solve real-time load dispatch optimization problem. With this algorithm in place, generators with maximum cost-per-unit generation power are to be shut off. The proposed shut-off criteria use only quadratic function in power generation cost function without valve effect nonlinear absolute function. When applied to the most prevalent economic load dispatch benchmark data, the proposed algorithm is proven to largely reduce the power cost of known algorithms.
