This study was executed in order to analyze the purchasing practices, preferences, and satisfaction of consumers purchasing ready-to-eat foods. The study was executed from the $20\;May{\sim}30\;June$ 2007 in the Daegu and Gyeongsangbuk-do area. Questionnaires were distributed among 480 people. Of these, 410 questionnaires were collected and applied to a statistical analysis. Statistical analyses were conducted using the SPSS package program (version 14.0 for windows). The results of the statistical analyses were as follows. 42.4% males and 57.6% females participated in this study. The biggest motivation behind the purchase of ready-to-eat foods was convenience, 51.0%. The most common venues where these foods were purchased were supermarkets or discount marts, 67.6%. The ratio of substituting ready-to-eat foods for meals was 70.5%. The consumption practices of ready-to-eat foods of the consumers according to purchase place illustrated significant differences in the average expense per person each time (p<0.01), co-consumer (p<0.001), and age (p<0.05). The purchase preference was high with kimbaps (73.4%), hamburgers (29.8%), sushis (29.0%), and sandwiches (27.9%). Unmarried individuals showed a significantly higher overall liking and satisfaction for ready-to-eat foods than married individuals (p<0.001). Individuals living without a family was significantly higher overall liking and satisfaction than individuals living with a family (p<0.05). Individuals who spent an average of 10,000 won per time showed a significantly higher overall liking and satisfaction than those who spent below 10,000 won per time (p<0.05). In the presence of a friend as a co-consumer of ready-to-eat foods, satisfaction was significantly high (p<0.01). Consumers who purchased ready-to-eat foods at meal times, showed a significantly higher overall liking, compared to those who purchased such food products in between meal times (p<0.01). The preference and satisfaction degree of the consumer must be reflected by product development, quality improvement and marketing plan establishment.
Community Attachment variables(specially, system model variables : gender, age, education, income, number of children, marital status, length of residence, and job) have been tested. The data for this study were collected from 295 residents of Yesan in Chungnam. The SPSSWIN package was utilized for data analysis. Frequency, percent, t-test, and ANOVA were utilized for statistical analysis. Each hypothesis was tested at .01, .05, and 01 level. The major findings of this study were: 1) the range of community attachment score was $17{\sim}56$. The mean score of community attachment was 29.8 with a standard deviation of 5.34. 2) t-test showed that job was statistically significant at .05 level among gender, marital status, and job. 3) length of residence, age, and numbers of children were statistically significant at .05, .10, and .01, respectively.
The aim of this study was to evaluate the effects of a nutrition education program for the elderly at a public health center located in Jinhae city. The one group pretest and posttest design was conducted using self-administered questionnaire survey. Nutrition education lessons based on social cognitive theory (2 hours/lesson, 3 times) were provided to 27 female elderly(${\geq}65$ yrs) for a month. After the nutrition education, number of exercise increased and preference for sweetness decreased significantly (p<0.05). The outcome expectations, the knowledge of nutrition (p<0.001), and behavioral capability (p<0.05) score were significantly increased. There were significant increases in all nutrient intake. NAR was increased significantly in protein, calcium and vitamin C (p<0.01), dietary fiber, iron, zinc, thiamin, niacin and folic acid (p<0.001), and riboflavin (p<0.05). INQ was increased significantly in thiamin, vitamin B6 and niacin (p<0.05), and dietary fiber (p<0.01). The score of nutrition education satisfaction was high (4.52). The results of this study suggested that the nutritional education program based on social cognitive theory had a positive effect on dietary behavior changes, and nutrition intake status among female elderly even after short-term intervention.
This study was designed to investigate whether applying mind mapping in a biology class had an effect on students' creativity. Participants of this study were 165 1st grade middle school students. The pretest-post test control group design was employed. A control group was instructed with a traditional method and an exerimental group was instructed using the mind-map applied method. The units "Digestion and Circulation" and "Respiration and Excretion" were selected for this study, and each group was treated for 24 class hours. To measure student creativity, the TTCT test was used. For assessing students' level of logical thinking, the compact version of GALT was used. Test results were analyzed by ANCOVA and correlation analysis by SPSS 12.0. The creativity of students in experimental group was significantly improved than the control group (p< .01). Fluency, flexibility, and originality of students in experimental group were improved (p< .01). Students did not show any differences on creativity according to their academic achievement level or gender (p> .05) in the experimental group. Students did not show any differences on creativity according to their logical thinking level (p> .05), either. However, the students of logical thinking level in the experimental group improved their flexibility (p< .05). There was no correlation between students' creativity and their achievement (p> .05), but the creativity shows a lower correlation to performance evaluation (p< .05).
This study evaluated the nutrient adequacy ratio (NAR) and depression based on the sleep duration of adult women using data from the Korea National Health and Nutrition Examination Survey (KNHANES) 2016 and 2018. A total of 4,507 subjects were divided into two groups: sleep hours<7 (lack of sleep, LS) and 7≤sleep hours (normal sleep, NS). For a more detailed analysis, the subjects were further divided into normal sleep with no depression (NSND) and lack of sleep with depression (LSWD) groups. When compared with NS group, the nutrient intake of the LS group was observed to be higher in carbohydrates (P<0.05) and thiamine (P<0.01), but had a significantly lower mean nutrient adequacy ratio (P<0.05). Also, the LS group showed a higher frequency of early menopause (P<0.001) and depression (P<0.05) than the NS group. In the analysis of anthropometry and blood parameters of the subjects based on their sleep duration, the LS group showed a lower body mass index (BMI, P<0.05), lower blood creatinine (P<0.01), glycated hemoglobin (P<0.05), and high-density lipoprotein (HDL) cholesterol (P<0.01) levels adjusted by age and menopause than the NS group. When compared to the NSND group, the LSWD group had a lower intake of cholesterol (P<0.05), vitamin A (P<0.05), vitamin C (P<0.05), and folic acid (P<0.05). There was no variation in the menopausal status, NAR, and mean nutrient adequacy ratio between the NSND and LSWD groups. However, there were differences in total blood cholesterol (P<0.05) and depression based on sleep duration. Apart from nutritional status, differences in BMI and blood parameters were observed based on sleep duration.
To examine the effects of an educational program with a purpose of reducing symptoms and ailments of women's premenstrual syndrome on the basis of the Self-care theory of Orem, a stimulation was carried out by using pre-and post-design of non-equity control group after choosing both an experimental group of 62 persons and a control group of 62 persons among 497 industrial women. This study was conducted from June 20, 1996 to September 30, 1996. Meantime, an education was provided for the experimental group of 62 persons for 8 weeks but no education for the control group of 62 persons. Study matters are general and obstetric characteristics, knowledge and self-care behavior and premenstrual syndrome from questionnaires with 497 industrial women, pre and post questionnaires with the control group of 62 persons and the questionnaires collected before and after providing an education for the experimental group of 62 persons, these matters were used as research data for this study and analyzed by means of the SAS program. As a result, it was shown that the scores of 497 industrial women's knowledge by age were the highest 26.36 for 20 to 29 year old women, then 25.58 for 30 to 39 year old women and 25.74 for less 19 year old women. The performance scores of their self-care behavior by age were the highest 39.17 for 30 to 39 year old women, 35.72 for 20 to 29 year old women and 32.85 for less 19 year old women, which means that the older the women are, the higher the performance degree is(p<0.01). And the scores of their premenstrual syndrome by age were 2.80 for less 19 year old women, 2.18 for 20 to 29 year old women and 2.00 for 30 to 39 year old women. Women in their teens and twenties showed more serious symptoms and ailments of premenstrual syndrome than women in their thirties(p<0.01). For the experimental group of 62 persons who received the educational program, both the knowledge of premenstrual syndrome and the degree of self-care behavior were remarkably improved(p<0.01), respectively and the symptoms and ailments of premenstrual syndrome were also remarkably reduced(p<0.01), while the control group showed no change in the knowledge, self-care behavior, and symptoms and ailments of premenstrual syndrome. The above results demonstrated that educational program based on the Self-care theory of Orem is an effective intervention to reduce the symptoms and ailments of premenstrual syndrome. The effects of the study can be generalized by extending the application in which various age groups and professional and social environments are considered together with a research to evaluate the long-term effects of this educational program. Accordingly, it is expected that it can possible not only to provide help for the women by actually applying the program to practical areas for improvement of women's health but also to suggest plans to activate it as one of health education areas.

Purpose: This study aimed to demonstrate reduction in stroke symptoms by analyzing the changes in respiratory function and activities of daily living (ADL) after respiratory muscle strengthening exercise in patients who had a stroke and thereby, propose an efficient exercise method. Methods: Twenty patients with hemiplegic stroke were divided into two groups, with 10 patients in each. The control group (CG) received the traditional exercise therapy, and the experimental group (EG) received the traditional exercise therapy combined with expiratory muscle strengthening training. The training continued for 6 weeks, 5 days a week. Forced vital capacity (FVC) and forced expiratory volume at 1 second (FEV1) were measured with a spirometer, $SpO_2$ was measured with a pulse oximeter, and ADL were assessed by using the modified Barthel index (MBI). A paired t test was applied to compare the differences before and after the intervention, and an independent t test was used to compare the differences between the groups. The level of statistical significance was set as ${\alpha}=0.05$. Results: The changes in the FVC and FEV1 values within the group showed significant differences only in the EG (p<0.01). The between-group difference was statistically significant only for FVC and FEV1 in the EG (p<0.01). The changes in $SpO_2$ and MBI within the group showed significant differences only in the EG and CG (p<0.01). Between-group differences were statistically significant only for $SpO_2$ and MBI in the EG (p<0.05). Conclusion: The interventions with active patient involvement and combined breathing exercises had a positive impact on all the functions investigated in this study.
1988년 7월부터 1989년 6월까지 서울시소재 동물병원에 내원한 환견 87두를 대상으로 질환별 혈액화학치검사를 실시한 결과 다음과 같은 결론을 얻었다. 1. 소화기계 질환군에서는 혈당치와 A/G비의 평균치는 각각 질환견이 $40.8{\pm}22.4$mg/dl와 $0.73{\pm}0.28$로서 건강견의 $60.4{\pm}22.0$mg/dl와 $1.06{\pm}0.17$보아 감소하였다(p<0.01). 2. 기생충 질환군에서는 GOT와 BUN의 평균치는 각각 질환견이 $29.4{\pm}72$IU/l와 $29.8{\pm}13.6$mg/dl로서 건강견의 $25.9{\pm}5.2$IU/l와 $17.3{\pm}4.9$mg/dl보다 증가하였다(p<0.01). 3. 필요기계 질환군에서는 BUN의 평균치가 질환견에서는 $49.5{\pm}16.7$mg/dl로서 건강견의 $17.3{\pm}4.9$mg/이보다 증가를 보여 1$\%$ 수준의 높은 유의성이 인정되었다. 4. 각 질환군에서 Total Protein치의 변동은 인정되지 않았다.
Tumor necrosis factor ($TNF-{\alpha}$), an inflammatory cytokine that plays an important role in the control of cell proliferation, differentiation, and apoptosis, has previously been used in anti-cancer therapy. However, the therapeutic applications of $TNF-{\alpha}$ are largely limited due to its general toxicity and anti-apoptotic influence. To overcome this problem, the present study focused on the effect of active constituents isolated from a medicinal plant on $TNF-{\alpha}$-induced apoptosis in human colon adenocarcinoma (HT-29) cells. Nimbolide from Azadirachta indica was evaluated for cytotoxicity by methyl tetrazolium 3-[4,5-dimethylthiazol-2-yl]-2, 5-diphenyltetrazolium bromide (MTT) assay and phase contrast microscopy. Effects on apoptotic signaling proteins were investigated using Western blot analysis. Nimbolide showed cytotoxicity against HT-29 cells that was significantly different from the control group (p<0.01), a concentration of $10{\mu}M$ significantly inducing cell death (p<0.01). In combination with $TNF-{\alpha}$, nimbolide significantly enhanced-induced cell death. In apoptotic pathway, nimbolide activated c-Jun N-terminal kinase (JNK) phosphorylation, BH3 interacting-domain death agonist (Bid) and up-regulated the death receptor 5 (DR5) level. In the combination group, nimbolide markedly sensitized $TNF-{\alpha}$-induced JNK, Bid, caspase-3 activation and the up-regulation of DR5. Our findings overall indicate that nimbolide may enhance $TNF-{\alpha}$-mediated cellular proliferation inhibition through increasing cell apoptosis of HT-29 cells by up-reglation of DR5 expression via the JNK pathway.

Objective: This study was to estimate heritabilities, additive genetic correlations, and phenotypic correlations between number of piglets born alive (NBA), litter birth weight (LTBW), number of piglets weaned (NPW) and litter weaning weight (LTWW) in different parities of Landrace (L), Yorkshire (Y), Landrace×Yorkshire (LY), and Yorkshire×Landrace (YL) sows in a commercial swine operation in Northern Thailand. Methods: Two models were utilized, a single trait repeatability model (RM) and a multiple trait animal model (MTM). The RM assumed reproductive records from different parities to be repeated values of the same trait, whereas the MTM assumed these records to be different traits. The two models accounted for the fixed effects of farrowing year-season, genetic group of the sow, heterosis, and age at first farrowing, and the random effects of sow, boar, and residual. Results: Heritability estimates from RM were 0.02±0.01 for NBA, 0.10±0.01 for LTBW, 0.04±0.01 for NPW, and 0.11±0.01 for LTWW. Heritability estimates from MTM fluctuated across parities, ranging from 0.04±0.01 in parity 2 to 0.09±0.02 in parity 4 for NBA, 0.07±0.02 in parity 2 to 0.16±0.02 in parity 3 for LTBW, 0.04±0.02 in parity 4 to 0.08±0.01 in parity 1 for NPW, and 0.16±0.02 in parity 1 to 0.20±0.02 in parity 2 for LTWW. Additive genetic correlation estimates from MTM were also variable, ranging from 0.29±0.24 between NBA in parity 1 and NBA in parity 2 to 0.99±0.05 between LTWW in parity 3 and LTWW in parity 4. Conclusion: The findings of this study highlight the advantage of using MTM for the genetic improvement of reproductive traits in swine and contribute to the development of sustainable swine breeding programs in Thailand.
