  • The multivariate analysis techniques of cluster analysis are examined in this article. The theory and applications of the techniques and computer software concerning these techniques are discussed and sample jobs are included. A hierarchical cluster analysis algorithm, available in the IMSL software package, is applied to a set of data extracted from a group of subjects for the purpose of partitioning a collection of 26 attributes of a weapon system into six clusters of superattributes. A nonhierarchical clustering procedure were applied to a collection of data of tanks considering of twenty-four observations of ten attributes of tanks. The cluster analysis shows that the tanks cluster somewhat naturally by nationality. The principal componant analysis and the discriminant analysis show that tank weight is the single most important discriminator among nationality although they are not shown in this article because of the space restriction. This is a part of thesis for master's degree in operations research.

  • The purpose of this research was to analyze the relationship between the ease of crotch depth and the mobility of leg movement. Ten Korean men were participated as subjects and 0. 3, 6cm of crotch ease were inserted for test clothes. To analyze objectively, range-of-motion of four selected movements was measured by Leighton flexometer and goniometer. Also. wearer acceptability rating was measured for subjectively investigation. Anova and Duncan's range tests were used for statistical analysis. According to the results, 3cm of crotch ease was most comfortable. The mobility of test clothes with 3cm crotch ease was improved largely in every test movement(16.2% and 16.6% in segittal plane, and 6.1% and 6.2% in frontal motion).

  • The purpose of this study is 1) to investigate the phoneme inventories and phonological processes of cochlear implant(CI) children and 2) to describe their utterances using narrow phonetic transcription method. All ten subjects had more than 2 year-experience with CI and showed more than 85 % open-set sentence perception abilities. Average consonant accuracy was 81.36 % and it was improved up to 87.41% when distortion errors were not counted. They showed similar phonological processing patterns to HA or normal hearing children in some way as well as different phonological processing patterns from HA or normal hearing children. The prominent distortion error pattern was weakening of consonants. Every subject had his/her idiosyncratic error pattern that demanded his/her own individualized therapy program.

  • This study was performed to investigate some characteristics on human error proneness in the computerized work environment. Our concerning theme was on human error likelihood according to personal temperament. Two experiments were performed. The first experiment was to study the effect of field- independence/dependence on error likelihood. The second experiment was on error proneness. These experiments were performed in information search task. which was most frequent task in computerized work environment such as the control room of nuclear power plant. Ten subjects were participated in this study. Analyzed results are as follows. Field-independence/dependence had a significant effect in both information search time and error frequency. Error proneness had a significant effect in both factors, too. And, a positive correlation was found between error frequency and information search time. These results will be utilized as a basis to study operator's error proneness in the computerized control room of nuclear power plant. later on.

  • This study was conducted to investigate nutrient and food choices in gastric cancer patients receiving Cisplatin after surgery. Ten patients were followed from the fist day of the first cycle to the last date of the 6th the cycle of the chemotherapy. The subjects kept daily self record of dietary intake and the period of nausea/vomiting during 6 cycles. Using Computer Aided Nutritional Analysis Program, the degree of Calorie, carbohydrate, protein, fat and fluid intakes according the chemotherapy period. The reseacher developed food intake rating scale, and then three dietitians analysed the oral intakes according to the type of foods. As the results of this study, during the chemotherapy cancer patients are intakes much fewer calorie, protein and fluids than recommended dietary allowance. Oral intake was worsen as treatment proceed. During the chemotherapy periods most of the patients choose fruits, vegitables, steam rice, porridge, yogurt and the beam soup to overcome nausea and vomiting. In order to promote oral intake for chemotherapy patients, the researcher strongly suggest that indiviual food preform should be considered.

  • Objectives: The purpose of the study was to investigate dental care effects of periodontal diseases patients with systemic diseases. Methods: The study subjects were ten patients. The study consisted of direct examination and interview survey. Direct examination comprised pocket depth, bleeding on the brush, O'Leary plaque record, salivary flow rate, and oral bacterial culture for three months. Results: The number of diabetic patients was eight. Four patients xerostomia and one of them had 0.7 mL per minute of salivary flow rate, decreased O'Leary plaque record, and bleeding in the brush. Those who received education were able to take control of plaque management. They recognized the need for oral care and had good self-management of oral care skills. Conclusions: The professional dental care and oral health education improved periodontal health and self-management skills of plaque in periodontal disease patients with systemic diseases.

  • Acoustical correlates of stress can be classified as duration, intensity and fundamental frequency. This study examined the acoustical differences in the first two syllables of stressed English words produced by ten American and Korean speakers. The Korean subjects scored very high on the TOEFL. They read at a normal speed a fable from which the acoustical parameters of eight words were analyzed. In order to make the data comparison meaningful, each parameter was collected at 100 dynamic time points proportional to the total duration of the two syllables. Then the ratio of the parameter sum of the first rime to that of the second rime was calculated to determine the relative prominence of the syllables. Results showed that the durations of the first two syllables were almost comparable between the Americans and Koreans. However, statistically significant differences showed up in the diphthong pronunciations and in the words with the second syllable stressed. Also, remarkably high r-squared values were found between pairs of the three acoustical parameters, which suggests that either one or a combination of two or more parameters may account for the prominence of a syllable within a word.

  • This study deals with the disguised voice (or voice disguise) in the field of forensic phonetics. We especially studied the effects of the methods of disguised voice on the aural decision. Within the nonelectronic-deliberate voice disguise area, the methods of disguised voice include use of lowered pitch, pinched nostrils, falsetto, and whisper. Ten (male:5, female:5) Seoul speakers made a recording of 16 sentences. In the aural test, 30 subjects listened normal and disguised voice. And they were asked to make a decision whether speakers identified or not. The result is as follows: The speaker verification of the falsetto and whisper was more difficult than the lowered pitch and pinched nostrils.

  • The purpose of this study is to investigate prosodic characteristics in the speech of adults with cerebral palsy through a comparison with the speech of normal speakers. Ten speakers with cerebral palsy (6 males, 4 females) and 6 normal speakers (3 males, 3 females) served as subjects. The results revealed that, compared to normal speakers, speakers with cerebral palsy showed a slower speech rate, a larger number of intonational phrases(IPs) and pauses, a larger number of accentual phrases(APs) per IP, a longer duration of pauses, and more gradual slopes of [L +H] in APs. However, the two groups showed similar tone patterns in their APs. The results also showed mild to moderate correlations between speech intelligibility and the prosodic properties which showed significant differences between the two groups, suggesting that they could be important prosodic factors to predict speech intelligibility in the speech of adults with cerebral palsy.
