This study evaluated the effects of low-dose X-ray irradiation treatment on quality characteristics and sensory evaluation of imported navel oranges during storage at $20^{\circ}C$ for 12 days. The samples were irradiated at doses of 0.2, 0.4, 0.6, 0.8, and 1.0 kGy, and changes in color value, hardness, Brix/acid ratio, total sugar content, reducing sugar content, vitamin C content, and sensory evaluation were investigated. There were no significant differences between non-irradiated and irradiated samples in terms of color value, Brix/acid ratio, total sugar content, reducing sugar content, and vitamin C content. Difference in hardness between non-irradiated and irradiated samples decreased at the end of storage. Reducing sugar content was reduced as storage period increased. The sensory evaluation scores of non-irradiated and irradiated samples were not significantly different according to storage period, except for sweetness and texture. Overall acceptability was not significantly different by irradiation dose or storage period. These results suggest that X-ray irradiation does not affect quality characteristics or sensory evaluation.

The purpose of this study was to identify the prevalence of urinary incontinence and its relating factors elderly communities. Subjects of this survey consisted of 877 elderly women and men in one Kun. Korea, who were over 60 years old. The design for this study was descriptive: the subjects were interviewed by well trained investigators from July 9. 1999 to July 20. 1999. During that survey period, the subjects were interviewed with a structured questionnaire. The data were analyzed by frequency, percentage, $X^2-test$. T-test using an SAS program. The results of the study were the following: 1. The prevalence rate of urinary incontinence was 20.1 %. of the total. The types of urinary incontinence were mixed incontinence 44.3%. stress incontinence 38.1%. and urge type incontinence 17.6%. 2. The relating factors of urinary incontinence were as follows: 1) 33.5% of UI(urinary incontinence) subjects reported urine loss once a month. twice or three times a week 23.3%. one or two times a day 17.0% 2) 38.1% of elderly reported only 1 to 2 drops. 1 t-spoon 36.9%. 1 T-spoon 15.9% 3) The volume of urine loss registered by changing underwear was 63.1 %. no necessity of changing underwear was 22.1 %. or using some type of pads was 13.1%. 4) 62.5% of UI subjects never discussed their UI problem with other people. 73.9% of the total had never experienced any treatment for their UI problem. The reasons for not receiving medical cure were their typical conception about urinary incontinence taking UI as a normal part of aging 76.2% and due to their bad financial situation 9.2%. 3. Women had more prevalence of UI than men (p=0.01), and it was found that the worse the subjective health state. the higher the prevalence of UI (p=0.001). However. there was no statistical difference in daily frequency of UI (p>0.05). The more nocturnal incontinence (p=0.001), the more intermittent stream experience (p = 0.01), the more retention experience (p = 0.01), and the more incomplete the emptying experience (p=0.001), the higher the prevalence of UI. 4. UI groups had lower ADL scores than non UI groups(p=0.01). The level of depression in the group of urinary incontinence was significantly higher than that of non incontinence group (p=0.0001). As shown above, the elderly people suffering from UI haven't been treated properly: their subjective health state and their ADL competence was lower, and their depression level was higher than non UI groups. Therefore, the development of a proper urinary incontinence management program are required so that they can lead more healthy lives. Also continual case studies for the elderly people with UI are necessary.

A study has been conducted on developing questionnaires to serve as on site diagnostic tools for the early detection of neuropsychiatric impairment among workers chronically exposed to low-level organic solvents. Two drafts of tentative questionnaires have been developed as follows; several question items were selected from questionnaires which were administered to workers exposed to organic solvents in previous studios and were grouped into each symptom category based on the presence of its association using Guttman scaling method, then these selected items were reviewed by neuropsychiatry specialists. The final draft of the questionnaire (total symptom score=36) was developed by selecting 33 question items which had more than a 0.88 Guttman coefficient of reproducibility in each symptom category from a pilot study in which these tentative questionnaires were administered to workers manufacturing soles. Three plants using organic solvents and one plant never using organic solvents as a control group were selected to test the reliability and validity of the developed questionnaires. The major organic solvent in the workplace environment detected by a personal air sampler and GC/MSD nab toluene. The concentration of toluene in air from the department using organic solvent was statistically different from that of the department never using organic solvent. The concentration of toluene from almost all of the workplace did not exceed the allowable level. There was no statistically significant difference between the concentration of urinary hippuric acid from the workers of the department using organic solvent and that of the department never using it. Total symptom score of the plant never using organic solvents was 9.8 and those of the three plants using organic solvents were 15.6, 14.7, and 13,7 respectively. In order to evaluate the validity of the questionnaires, the workers from two different departments of the plant in which usage of organic solvents are totally dofferemt were compared. The total symptom score was 17.8 for workers of the department using organic solvent and 13.5 for the department never using organic solvent and scores of each symptom group between exposure and non-exposure group also showed statistically significant difference. The finding that total symptom score of the exposure group increased as the duration of employment increased indirectly suggests the usefulness of the developed questionnaire to assess the health effects of chronic exposure to organic solvents. The correlation coefficient, which was calculated to evaluate the test-retest reliability, was 0.581 (p=0.001). The coefficient of Crohnbach which reflects the internal consistency of the questionnaire was 0.91. In conclusion, the reliabilty of the questionnaire was well maintained over the time lapse between the two administrations of the questionnaire and despite the seasonal difference.

Associated with microbial decontamination and quarantine treatment of dried red pepper, the samples was gamma-irradiated (5, 10 kGy) and fumigated (methyl bromide/MeBr, phosphine/$PH_3$) to compare their Hunter's color (L, a, b, ${\Delta}E$) and sensory properties by types (whole, powder, pericarp, seed) during storage under room conditions($18{\pm}12^{\circ}C$). Whole pepper maintained higher lightness (L value) than other groups, while powdered pepper showed higher redness (a value) during storage. Immediately after treatments there was little difference in the overall color difference (${\Delta}E$) among the groups. After 8 months, a higher redness was observed in $PH_3$ group of whole pepper and 5 kGy group of powdered pepper, respectively(p<0.05). Redness of irradiated pericarps was apparently reduced following 8 months of storage and a similar pattern was found in fumigated samples. The yellowness (b value) of pepper seed was lowest in 10 kGy sample (p<0.05), but insignificant difference was observed among treatment groups with storage time. Sensory properties of whole and powdered peppery were little changed by both treatments under commercial conditions. Sensory scores of irradiated or fumigated samples were higher than that of non-treated control with storage time, which was more significant in the powdered than in the whole samples.

In order to analyze the pathomechanisms of dysmenorrhea and efficiency of DSOM(diagnosis system of oriental medicine), clinical test was performed for 541 childbearing women having menstrual pain in P metropolitan city. The experimental group was composed of subjects who experience discomfort in daily life or interpersonal activities caused by menstrual pain with scores of 4 or above on the measurement of menstrual pain (MMP). The control group was composed of subjects reporting little or no discomfort with scores of 3 or below on the MMP. The menstrual period measurements were taken within 2-3 days following the first day of menstruation, when menstrual pain is at its peak. While non-menstrual period measurement were within 7-10 days after the last day of menstruation. The dampness pathomechanism was yielded most frequently in both groups, and then heart、heat、blood deficiency、cold、qi deficiency、phlegm、qi congestion、blood stasis in order. And the significant differences were in the pathomechanisms of blood deficiency、blood stasis、qi congestion、five viscera、phlegm and cold between the two groups. This means that general pathomechanisms of childbearing women in twenties mainly are dampness and heat, especially the experimental group has mostly disharmony of six qi and/but then move to insufficiency and stagnation of qi and blood and then to visceral disease pattern having statistically significant difference. Moreover in the two times of investigation, the output of pathomechanisms in each group has similar pattern in the same group. Therefore it can be concluded that the results of pathomechanisms by DSOM were in accordance with existing pattern classifications of dysmenorrhea in general and the DSOM showed reproducibility and stability in the data processing of questionnaires.

This study was carried out to test the effects of fluorescein diacetate(FDA 0${mu}ell$/ml, 0.5${mu}ell$/ml, 5${mu}ell$/ml, 10${mu}ell$/ml or 0${mu}ell$/ml, 5${mu}ell$/ml in PBS) treated before culture on the survival of vitrified mouse morulae in vitrification solution(20% glycerol＋glycerol＋10% ethylene glycol＋30% ficoll＋10% sucrose). The results were summarized as follows; 1. The survival rate of FDA-tested fresh mouse morulae after 24 hours culture was over 96%((P4.8) in the control or treatment groups with various levels of FDA. Because the rate of mouse morulae which developed to hatched blastocysts was higher with the various levels of FDA treatment(67%) than control(50%), it was considered that toxicity of FDA did not affect the survival of mouse morulae. 2. When mouse morulae were FDA-tested in FDA 0(control), 0.5, 5, and 10${mu}ell$/ml treatment after vitrification, the development rate to expanded blastocyst were 66, 82, 64 and 76%, and FDA scores were P4.2(84%), P4.7(94%), P4.2(84%) and P3.9(78%), respectively. There were no significant differences between control and FDA treatments, but there were significant difference between 0.5${mu}ell$/ml)94%) and 10${mu}ell$/ml(78%) treatment(P<0.01). 3. The survival rates of cultured mouse morulae according to FDA-scores(P0=non-fluorescence; P1~P5=according to their fluorescence) after vitrification were P5;92%, P4;67%, P3;42% and P2.P0;0%, respectively. 4. Implantation rates of morulae stage embryos cultured into early blastocysts and implanted into uterine hornes vitrification were 14 and 11% embryos treated control(0${mu}ell$/ml) and FDA 5${mu}ell$/ml and the normal fetus development was 2% embryos for both treatments. Results of this percent study indicated that toxicity of FDA does not affect not only the survival of fresh and vitrified mouse morulae but also the development rate and implantation of fetus after transfer as well. The development rates of mouse morulae with the FDA score of P5, P4 and P3 were 92, 67 and 42%, respectively, it was considered that FDA-test was fit for the judge of survival.

Food neophobia, unwillingness to try novel foods, is a personality trait that can influence children's food preferences and consequently their food acceptance and consumption. The purpose of this study was to determine whether children with food neophobia have poor dietary and growth outcomes compared to non-neophobic children. Subjects were 332 primary school children from 6 randomly selected schools in the district of Hulu Selangor, Selangor. Parents and children were interviewed to obtain demographic, socio-economic, food neophobia and dietary intake information. The children were also measured for weights and heights. One-way ANOVA and Chi-square procedures were utilized for statistical data analysis. Children with food neophobia had higher intakes of energy and most nutrients than average and neophilic children. However, only the mean intakes of protein (p < 0.05) , fat (p < 0.05), vitamin A (p < 0.01) and iron (p < 0.01) were significantly higher in neophobic than average or neophilic children. Compared to neophilic and average groups, a higher percentage of neophobic children met 2/3 of the RNIs for energy $(85.2\%)$, protein $(98.4\%)$ and vitamin A $(72.1\%)$. Mean percentage of carbohydrate energy was lowest$(54.8\pm6.6\%)$ while fat energy $(31.8\pm6.2\%)$ was highest among neophobic children. Neophobic group had the lowest percentage of children $(49.2\%)$ with carbohydrate energy > $55\%$ but highest percentage $(50.8\%)$ with fat energy > $30\%$. For the three study groups, the mean number of servings for all food groups, except grain and cereal, did not meet the Food Pyramid recommendations. Neophobic children consumed significantly more numbers of servings from the meat group than average and neophilic groups (p < 0.01). All study groups had relatively low mean dietary diversity scores but neophobic children had the lowest score $(0.67\pm0.73)$ compared to the average $(0.97\pm0.72)$ and neophilic $(1.98\pm0.81)$ groups. Significant difference in mean dietary diversity scores were only observed between neophobic and neophilic children (p<0.05). Higher percentages of neo-phobic children had low weight-for-height and were at-risk of overweight(p < 0.05). Nutrition practitioners need to understand children's food preferences in their efforts to promote healthful diets for children. To improve children's eating behaviors, parents may need the guidance and support from nutritionists and dietitians that are specific to their needs and their child's situation.

Objectives: We aimed to compare the quality of sleep, tongue diagnosis, oral microbiology differences in insomnia of Liver qi stagnation (LQS) and Non-Liver qi stagnation (NLQS). Methods: 56 patients were classified as LQS or NLSQ type insomnia through the insomnia differentiation questionnaire. The depression scores between the groups were compared through beck depression inventory (BDI), and the sleep quality was compared through Pittsburgh sleep quality index (PSQI) and Insomnia Severity Index (ISI). We analyzed the sleep efficiency, total sleep time, total awake frequency, total and average awake time through actigraph. For the tongue diagnosis, the distribution of tongue coating in six areas were measured through Winkel tongue coating index (WTCI). Linear discriminant analysis was performed to observe the differences in composition of microbial strains between the groups. Results: The scores of BDI, ISI and PSQI were significantly higher in LQS group. The total sleep time in LQS group was significantly less than that of NLQS group. Among the areas of tongue, according to the WTCI, the amount of tongue coating in zones A and C was significantly small. In oral microbial analysis, there was no significant difference between the groups at the phylum level. At the genus level, Prevotella, Veillonella, and Streptococcus were predominant in LQS group, whereas Prevotella, Neisseria, and Streptococcus in NLQS group. Conclusions: It was meaningful that insomnia was more likely in LQS group than in NLQS group, and the composition of oral microorganisms was significantly different, which could lead to the diseases caused by stress.

This study is a comparative descriptive research that identifies the degree and difference of the brain education meditation program from participation stress(physical stress, psychological stress), depression, resilience(self-control ability, interpersonal relationship ability, and positive) for middle-aged women. The subjects were 26 middle-aged women who participated in the brain education meditation program at the D metropolitan city D center for more than a year, 29 middle-aged women did not participate in the brain education meditation program and a total of 55 middle-aged women collected for three weeks from November 4 to 22, 2019. Data analysis fesult that the participating groups in brain education meditation programs differ statistically significantly in physical stress(t=2.549, p=.014), psychological stress(t=2.352, p=.022), self-control ability(t=-2.219, p=.031) and positive(t=-2.387, p=.021), which are higher factors in resilience than non-participating groups. In other words, brain education meditation program participants scored lower physical and psychological stress scores than nonparticipating groups, with higher self-control ability and positive scores. Therefore, it is thought that brain education meditation programs can be used as nursing intervention to reduce stress and improve self-control ability and positive in middle-aged women.
