JOURNAL FREE ACCESSOrdinary time-series analysis operates on time-series data measured on interval or ratio scale. However we often encounter time-series data measured on nominal scale especially in humanity science. In such cases, it is an important research activity to find systematic trend in the qualitative data. In order to achieve this purpose, Time-Series Analysis of Qualitative Analysis was developed by Inagaki (1997). In this paper, we mathematically explain the method extended to data constrained, and discuss the relation to other methods.View full abstractDownload PDF (837K) -
Comparison between male junior college and college studentsHiroki FUJIGAWA, Susumu TAMURA, Takeshi SEKIYA, Tetsufumi MURA1999 Volume 1999 Issue 27 Pages 10-20

JOURNAL FREE ACCESSThe purpose of this study was to investigate the relationship between the lifestyle and mental health of male junior college and college studennts who were of same age. By means of questionnaire, samples of lifestyle and KMI (Kyudai Medical Index) were obtained from 4 groups: 68 junior college freshmen who lived with family, 33 freshmen who lived alone, 194 college freshmen who lived with family, 163 freshmen who lived alone. The results were as follows:
1. College students are higher than junior college students in mean scores of most KMI items, and students who lived with family are higher than students who lived alone.
2. Both junior college and college students who lived with family showed desirable lifestyle in sleep and dietary habits on weekdays.
3. From a viewpoint of lifestyle and mental health, junior colllege students had better record than college students, and students who lived with family had higher score than students who lived alone.
4. It is considered that among the factors which affected the mental health of students are their trouble, stress, adaptability to the college life.View full abstractDownload PDF (1680K) -

JOURNAL FREE ACCESSThe purpose of this study was to examine the lifestyle and physical fitness of male junior college students in comparison with those of male college students. By means of questionnaire and physical fitness test, samples of lifestyle and fitness data were obtained from 2 groups: 82 junior college and 401 college students. Furthermore, their heart rates during daily activities in each 20subjects-group were recorded continuously throughout day and night by using heart rate recorder.
As a result, junior college students were superior to college students in back strength, vertical jump, and flamingo stand with closed-eye among physical fitness items. However, there was not a remarkable difference in the lifestyle and exercise habits of both groups. On the other hand, junior college students tended to be more active than college students from the viewpoint of heart rates. It might be caused by the curriculum of junior college which had practice classes more frequentlyView full abstractDownload PDF (2427K) -

JOURNAL FREE ACCESSIn this study, a linear model was applied in order to predict chronological age on the basis of independent variables such as blood pressure (SBP, DBP), maximal aerobic power (MAP), some measures of physical fitness (FLEX=standing trunk flexion, BALANCE=one foot balance with eye closed, SITUP=situps during 30sec., FAT=estimated percent body fat from skinfolds thickness), and DA=dental age from Sugiyam's estimation.
Sixty-seven males (18 to 60 years of age) as subjects participated in this study. The results of this study can be summarized as follows:
1) DA showed a fixed contribution for chronological age.
2) There was no relationship among dental attrition and physical fitness except SITUP.
3) As a result of stepwise regression analysis, the following model was established as optimal: y=36.3+0.424xDA-0.994xSITUP (R2=0.613).
4) The stability of this model was confirmed according to the analysis of residuals.
5) The model containing all variables is as follows: y=31.3+0.42xDA-1.08xSITUP+0.112xFLEX+0.008xBALANCE+0.036xMAP-0.019xSBP+0.103xDBP-0.094xFAT(R2=0.634)View full abstractDownload PDF (1242K)
