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.

This study explored the discrimination of synthesized English vowel pairs by twenty-seven American and Korean, male and female listeners. The average formant values of nine monophthongs produced by ten American English male speakers were employed to synthesize the vowels. Then, subjects were instructed explicitly to respond to AX discrimination tasks in which the standard vowel was followed by another one with the increment or decrement of the original formant values. The highest and lowest formant values of the same vowel quality were collected and compared to examine patterns of vowel discrimination. Results showed that the American and Korean groups discriminated the vowel pairs almost identically and their center formant frequency values of the high and low boundary fell almost exactly on those of the standards. In addition, the acceptable range of the same vowel quality was similar among the language and gender groups. The acceptable thresholds of each vowel formed oval to maintain perceptual contrast from adjacent vowels. The results suggested that nonnative speakers with high English proficiency could match native speakers' performance in discriminating vowel pairs with a shorter inter-stimulus interval. Pedagogical implications of those findings are discussed.

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 show the way of teaching the scietific talent in Japan. This study was conducted only by the printed matters. The results of the investigation are as follows: 1. Japan at present has neither systems nor laws for offical scientific talent education. 2. Japanese's scientific knowledge and way of rational thinking had been widespread among the general public by elementary education from one hundred ten years or so ago. 3. In addition, the instrument subjects such as foreign language and mathematics were well educated in the elementary and secondary school level and the preparatory courses of college. 4. Especially, the third and the first preparatory courses of a college(Daisan Koukou and Daiitchi Koukou) and Kyoto University have contributed greatly to the cultivation of liberal spirit in education, which turned out to be one of the essential elements for scientific talent education.

The purpose of this study is to analyze the relationship between the personality type and the residential evaluation & remodeling preference. The subjects of this investigation were collected through questionnaire from two hundred and twelve adult residents who live in Seoul, Korea. The collected cases are analyzed by using statistics software spss-win. The personality is classified eight types; E(extraversion), I(introversion), S(sensing), N(intuition), T(thinking), F(feeling), J(judging) and P(perceiving) in MBTI (Myers Briggs Type Indicator). By using the rotated component matrix of varimax method, the satisfaction of the actual residential conditions is classified into seven grouping factors. The preference of interior image is classified into thirteen factors. The important living patterns - activity, interest, and opinion - are classified into ten factors. And the important needs of residential remodeling are classified into twelve factors. By using the one way anova method, between these forty two grouping factors and personality type MBTI, there are analyzed several significances that will be useful in residential design and remodeling design & planning

In recent years, public attention to health and wellness issues has increased. The integration of smart fitness hardware and innovative technologies have made the development of smart fitness a trend. The number of fitness applications in the market has surged, and demand for an optimal experience is increasingly high. This study selects Sweatcoin, Home Workout, Six Pack in 30 Days, and Fitness Coach & Diet as research subjects from the top ten global mobile health and fitness apps in 2022 based on download rankings. The research is based on eight gamification elements: motivation, challenge, achievement, relationships, sharing, reward, level, and competition, identified through preliminary studies. We distributed a total of 166 questionnaires to users and collected 163 valid responses for data analysis. The Kano Model was used to study the desires of fitness enthusiasts using fitness apps. To reduce the limitations of the research results, the Better-Worse Method was employed for satisfaction index analysis. Based on the final analysis, we propose suggestions for improvement for the four fitness apps to better meet user needs and create a more attractive and efficient application experience.

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.

It is very common for women wear shoes with a high heel. It has been known that the high heel could disfigure the foot shape and cause various joint problems including back pain. However, few quantitative studies have been conducted. Therefore, in this study, the low back muscle has been investigated in order to find fatifue effect due to different heights of the heel. In particular, 0, 4, 6 and 8cm heel and two different shapes of heel have been used for an experiment. Ten healthy female subjects volunteered for the study. Isometric Trunk Exertion Frame(ITEF) and Electromyography were used to measure tha Median Frequency via Spectral analysis. The results indicated that the heel height significantly affected the local muscle fatigue of the back. After post hoc analysis, it was found that a proper heel height ougth to be lower than 5cm not to have severely fatigued back muscle after a casual walk for an hour. Such results could be applies to female industrial workers in order to prevent a cumulative trauma disorder of the back, and also to design a female dress shoes minimizing low back fatigue.

Rapid gas chromatographic profiling method was applied to saliva from healthy subjects for the analysis of free organic acids. Saliva samples were first saturated with NaHCO$_{3}$ and extracted with diethyl ether. The aqueous phase was solid-phase extracted using Chromosorb P as the adsorbent and diethyl ether as the eluent after the acidification and NaCl saturation, followed by triethylamine treatment. The resulting tiiethylammonium salts of acids were directly converted into stable tert.-butyl-dimethylsflyl derivatives, with subsequent analysis by dual-capiuary column gas chromatography and gas chromatograpy -mass spectrometry. From the ten saliva samples studied, twenty eight free organic acids including various fatty acids, hydroxy acids, dicarboxylic acids, md aromatic acids were tentatively identified. Among the acids identified , the concentration of lactic acid was highest for five saliva samples while $\alpha$-hydroxyisocaproic acid was most abundant for me sample, and succinic acid and glycolic acid for two samples. respectively. When the GC profiles were simplified to the corresponding acid retention index spectra of bar graphical form, they presented characteristic patterns for each individual.
