This survey was carried out to investigate the effect of self-consciousness of nutrition knowledge and health on the nutrition knowledge and on food habits between two groups of college women, a nutrition majors and a non-majors. Questionnaires were completed by 214 nutrition majors and by 145 nutrition non-major, Nutrition majors group scored significantly higher than nutrition non-majors in the nutrition knowledge. And nutrition non-majors scored significantly higher than nutrition majors in the food habits. Most of the subjects belonged to 'Fair' and 'Poor' food habit group. And also there was a significant correlation between the nutrition knowledge score and food habits score in nutrition majors and non-majors. There was a significant and positive correlation between nutrition knowledge score and food habits score in majors but it was not observed in non-majors. The higher majors had a self-consciousness of nutrition knowledge, the higher they had habit score and nutrition knowledge score, but in non-majors it was not observed. And non-majors who had a self-consciousness of health were healthier, they were higher in the food habits scores than the jai ors. The main curriculum it is important for a good food habits that one has a responsible nutrition education in main curriculum. For the Improvement of nutrition education program we should transmit the nutritional information through an effective mass media (i.e. Radio, TV, Newspaper).

Purpose: The purpose of this study is to identify the effects of suicide reports by mass media and social support on suicide ideation for college students. Methods: Participants are 350 undergraduate students in one university. This study uses three questionnaires: Perception and Attitude toward Suicide Reports, Social Support, and Suicidal Ideation. The SPSS/WIN 12.0 program is used to analyze the data. In particular, the participants' biographical data are analyzed into frequency and percentage. The degrees of suicide reports, social support, and suicide ideation are calculated into Mean and SD. Moreover, the suicide ideation by suicide report and social support are analyzed by the two-way analysis of variance (ANOVA). Results: This study reveals that college students have an average of 30 minutes to one hour news time a day (38.9%) and have at least one suicide report in a month (30.3%). 79.7% participants believe that the suicide report of mass media results in the cause of the copycat suicide. In terms of suicide report and suicide ideation, the types of mass media (F (4,340)=2.41, p<.05) and suicidal urge (F (1,340)=31.23, p<.01), respectively, have significant influences on suicide ideation. On the other hand, the social support and suicide ideation, whether college students have their mentors (F (1,328)=13.26, p<.001) and/or careres (F (1,328)=26.84, p<.001) have significant influences on suicide ideation. Conclusion: College students have higher suicide ideation at news by internet site rather than by radio, TV, and so on. Moreover, college students who have a suicide feeling in the last one year, have more suicide ideation than who have not. On the other hand, college students who have a mentor and carer tend to have less suicide ideation.

This survey was carried out to Investigate the effect of the daily average nutrient intakes, self-consciousness of nutrition knowledge and health on the nutrition knowledge and food habits between college women and their own mothers, Questionnaires were completed by 214 college women who do major in nutrition and by 173 their mothers. The college women scored significantly higher than that of their mothers In the nutrition knowledge. And their mothers scored significantly higher than that of college women in the food habits. Most of the subjects belonged to 'Fair' food habit group, which was considered to be relatively good. The correlation of the scores between nutrition knowledge and food habits of the college women and their mothers was low. The daily average nutrient Intakes of all women were higher than the recommended dietary allowance except for that of Iron. There was a significant and negative correlation between the nutrition knowledge score and daily average nutrient intakes in college women. But there was not a significant correlation in the nutrient intakes in their mothers. And also there was a significant and positive correlation between food habits score in their mothers but there was not a significant correlation score in college women. The higher the women had a self-consciousness of health, the higher their mothers had a food habit score, but they had daily average nutrient intakes were lower than their daughter's(college women), And the women that had a self-consciousness of health were healthier, daily nutrient intakes in their own mothers were higher in the food habits scores than that of the college women. The main curriculum for a good food habits is that it is important that one has a responsible nutrition education. For the improvement of nutrition education program we should transmit the nutritional information through an effective mass media(i. e. Radio, TV, Newspaper).

Low-ionization nuclear emission-line regions (LINERs) have been generally regarded to be powered by active galactic nuclei (AGNs), yet still a number of alternative explanations on the origin of LINER emission are suggested; for example, planetary nebulae nuclei of massive stars, supernovae shocks from death of massive stars, and old stellar populations. Interestingly, a majority of recent star formation early-type galaxies (ETGs) in local universe presents such LINER emission lines. Given that situation, revealing the true nature of LINERs is a crucial step to constrain the evolution path to quiescent ETGs. To resolve the issue, we use Keck/LRIS to obtain spatially resolved spectra on a carefully selected ETG. The ETG SDSS J091628.05+420818.7 at redshift z ~ 0.024 shows modest LINER emission line features without any detection of 21 cm radio continuum nor X-ray emission. We perform a stellar continuum subtraction and measure emission line strengths and their uncertainties for each spectrum from five apertures along the slit with size of 1 arcsecond (~0.5 kpc). We find that extended spatial distributions of four emission lines $H{\alpha}$, $H{\beta}$, [OIII]${\lambda}5007$, and [NII]${\lambda}6583$, and they can be explained by central emission blurring effect. We conclude that the emissions seem to be centrally concentrated, indicating the AGN-nature of LINERs.

Objective : This research was conducted to evaluate the method of sasangin classification by voice analysis, The 2 pilot tests were thus designed to solve the following problems: 'What are the conditions at classification for sasangin by the voice analysis?' and 'What are the important variances of /a/ parameter?'. Methods: 122 volunteers Were examined to make a diagnosis of sasangin by QSCC II and they were disease-free and healthy, First, they said /a/ three times for 2 seconds in their usual voice, Second, they said /a/ for 2 seconds by the different ways of high tone, mid tone, and low tone. The sounds were collected by a recording program (cooledit 2000) through a Sony microphone (ecm-26l). We analyzed the voices by maltlab, the simulation tool. Results: There were no differences and were correlations when one said /a/ three times for 2 seconds in the usual voice. There were some things to correlate when one said /a/ three times for 2 seconds by the different ways of high speech, usual speech, and low speech. Others were nothing to correlate. We evaluated the value of sasangin classification method by only /a/ voice analysis. The hit ratio was average $66.3\%\;:\;soyangin\;67.9\%,\;taeumin\;68.0\%,\;soeumin\;63.9\%$. Conclusion: We must set up the conditions to use the method of sasangin classification by voice analysis. The value of sasangin classification method by only fa! voice analysis was a hit ratio of $66.3\%$.

This study was conducted to examine arthritis patients' knowledge level and its related factors. Data were collected from 100 people who suffered from arthritis in Seoul, Busan, Daegu, Daejun, Junjoo, and Pohang from June 1, 2000 to August 31, 2000. The results of this study are summarized as follows. 1. 61.0％ of the subjects was female. The incidence rate of arthritis was higher in the higher age group, lower educated group, and thinner group. In the case of male, the incidence rate was higher in the groups of single, residents in big cities, and technicians. In the case of female, it was higher in the groups of the married, residents in towns or villages, and housewives. 2. Among the sources of obtaining the knowledge related to arthritis, 38.0％ of the respondents obtained the knowledge from physicians and 24.1 ％ got it from TV or Radio. 14.6％ of them obtained it from family members, neighbors, and friends and 14.3％ got it from newspapers, magazines, and pamphlets. Only 5.8％ of them obtained the knowledge from pharmacists. The sources showed significant difference in the variables of age, occupation, marital status, religion, place of residence, and education level. 3. 47.2％ of them thought that education related to arthritis was needed without fail, while 12.5％ thought that it was not necessary. In the question related to concern about arthritis, ‘no concern’ was 31.2％, while ‘concern’ was 7.8％ and ‘a little concern’ was 45.1 ％. 4. The knowledge level of arthritis was 7.35 ± 1.51 points on the basis of 11 points. It showed significant difference in the variables of age, occupation, education level, and economic status. 5. The knowledge was influenced by the variables of economic status, necessity of publicity, treatment period, occupation, education level, and age. The arthritis patients did not have enough knowledge of arthritis because the education was not provided well for them. Therefore, related professionals and organizations must develop education program of arthritis in order to educate them.

To establish good dietary behavior for middle school students, this study was conducted to analyze the needs of nutrition education and eating attitudes of 373 middle school students(boys 171, girls 202) in Hwaseong city. Using questionnaires, results were gathered and analyzed. Dietary behavior, food group intake and the needs of nutrition education were scored by a five-point Likert scale. Chi-square and student t-test were done for significant gender difference. The correlation between the needs of nutrition education with dietary behavior and food group intake was obtained by Pearson's r. The dietary attitude of 'try to eat first' and 'eating fast' were higher score in boys than in girls(p<0.05). Most of the students thought they didn't have any nutritional problems(71.8%). Nutrition education was considered necessary(54.9%) for proper growth and development(53.0%) in middle school. But 45.1% of students did not suggest by the reasons of 'short time to change'(28.2%), 'more effective in home'(27.4%). The appropriate time of nutrition education was pre-school(28.2%) or elementary school(27.4%), once a week(boys 51%, girls 71.3%) in frequency(p<0.001), and the information acquired by TV/Radio(30.0%) and internet(26.6%). Students(46.0%) wanted to know about 'growth and nutrition'. They were to learn information on the 'healthy growth'(4.10) and 'adolescent nutrition'(4.03). The vegetables group consumption and the thought of dietary attitude 'try to modify bad eating habits' were correlated with almost all categories of desired nutrition education. Through these results, good eating habits would be attained by nutrition education. A nutrition education program would require an expert teacher for middle school students.
