This study was performed to investigate the variation in dietary fiber and fat intakes, and the contribution of food groups to dietary fiber and fat consumption in relation to age and to examine the relationship between dietary fiber and fat intakes in 337 urban adults aged 20-49 year. Dietary intakes were evaluated with one-day 24-hour recall and two-day dietary record method. Significantly higher intakes of fat in males and saturated fatty acid, monounsaturated fatty acid, polyunsaturated fatty acid, and cholesterol in females were associated with younger age. The ratio of fat to the total energy intake slightly exceeded 20% at 20s and 30s in both males and females. The main source of dietary fiber was vegetables in all age groups of males and 30s of females, but grains in 20s and 40s of females. The main source of fat was meats in all age groups of males and 40s of females, but grains in 20s and 30s in females. The main source of cholesterol was eggs in both males and females. Dietary fiber intake was positively correlated with all fat-related parameters except cholesterol in 20s and 40s and was positively related with fat in 30s of males. For females dietary fiber intake was positively correlated with polyunsaturated fatty acid in 20s and with monounsaturated fatty acid and polyunsaturated fatty acid in 40s. These findings show that there is considerable variation in intake of dietary fiber and fat in relation to age among adults and suggest that these factors should be considered at interventions aimed toward improvement of nutritional status.

Background: The purpose of the present study was to investigate the differences in the position and shape of the anterior loop of the inferior alveolar nerve (ALIAN) in relation to the growth pattern of the mandibular functional subunit. Methods: The study was conducted on 56 patients among those who had undergone orthognathic surgery at the Gangnam Severance Hospital between January 2010 and December 2015. Preoperative computerized tomography (CT) images were analyzed using the Simplant OMS software (ver.14.0 Materialise Medical, Leuven, Belgium). The anterior and inferior lengths of ALIAN (dAnt and dInf) and each length of the mandibular functional subunits were measured. The relationship between dAnt, dInf, and the growth pattern of the mandibular subunits was analyzed. Results: The length of the anterior portion of ALIAN (dAnt) reached 3.34 ± 1.59 mm in prognathism and 1.00 ± 0.97 mm in retrognathism. The length of the inferior portion of ALIAN (dInf) reached 6.81 ± 1.33 mm in prognathism and 5.56 ± 1.34 mm in retrognathism. The analysis of Pearson's correlation coefficiency on all samples showed that the lengths of functional subunits were positively correlated with the loop depth. The length of the symphysis area in prognathic patients was positively correlated with the anterior loop depth (p = 0.005). Conclusions: Both the anterior and inferior length of ALIAN are longer in prognathic patients. Especially, it seems to be associated with the growth of the symphysis area.

Purpose: The purpose of this study was to identify differences of BMI, pain, depression, self-esteem and self-efficacy between rheumatoid arthritis and osteoarthritis patients. Method: The study subjects were 135 persons having chronic arthritis at rheumatology clinic and the department of orthopedic surgery of the C university hospital in D city. The data were collected from February 19th to April 7th, 2003. The data analysis consisted of $X^{2}-test$, t-test, Pearson Correlation Coefficient, and multiple regression using SPSSWIN 10.0 program. Result: 1. There were significant differences in age(p=0.000), occupation(p=0.015), marriage(p=0.028), duration of illness(p=0.000), BMI(p=0.006) and Self-efficacy(p=0.017) between rheumatoid arthritis and osteoarthritis patients. 2. In rheumatoid arthritis, the BMI and self-esteem(r=-0.239, p=0.05) were significantly correlated and also pain and self-esteem(r=-0.402, p=0.01), pain and self-efficacy(r=-0.455, p=0.01) were significantly negatively correlated. The self-esteem and depression(r=-0.622, p=0.01), self-efficacy and depression(r=-0.729, p=0.01) were significantly negatively correlated and also pain and depression(r=0.432, p=0.01), self-esteem and self-efficacy(r=-0.476, p=0.01) were significantly positively correlated. In osteoarthritis, the pain and self-esteem(r=-0.225, p=0.01) were significantly negatively correlated and also pain and self-efficacy(r=-0.493, p=0.01), self-esteem and depression(r=-0.692, p=0.01), self-efficacy and depression(r=-0.566, p=0.01) were significantly negatively correlated. The pain and depression(r=0.290, p=0.05), self-esteem and self-efficacy(r=0.383, p=0.01) were significantly positively correlated. 3. The factors influenced by the self-efficacy, the depression and age in rheumatoid arthritis explained 56.2%, the depression and pain in osteoarthritis explained 43.9%. The factors influenced by the BMI, the self-esteem in rheumatoid arthritis explained 5.7%, but there was no significantly variable in osteoarthritis. Conclusion: The results support the importance of different nursing intervention focused on BMI and self-efficacy in patients with rheumatoid arthritis and osteoarthritis. There is a need for further studies to identify relation of variables in different diseases related to arthritis.

The object of this study was to determine long-term temporal and spatial patterns of nutrients (nitrogen and phosphorus), suspended solids, and chlorophyll (Chl) in Chungju Reservoir, based on the dataset of 1992 - 2013, and then to develop the empirical models of nutrient-Chl for predicting the eutrophication of the reservoir. Concentrations of total nitrogen (TN) and total phosphorus (TP) were largely affected by an intensity of Asian monsoon and the longitudinal structure of riverine (Rz), transition (Tz), and lacustrine zone (Lz). This system was nitrogen-rich system and phosphorus contents in the water were relatively low, implying a P-limiting system. Regression analysis for empirical model, however, showed that Chl had a weak linear relation with TP or TN, and this was mainly associated with turbid, and nutrient-rich inflows in the system. The weak relation was associated with non-algal light attenuation coefficients (Kna), which is inversely related water residence time. Thus, values of Chl had negative functional relation (R² = 0.25, p < 0.001) with nonalgal light attenuation. Thus, the low chlorophyll at a given TP indicated a light-limiting for phytoplankton growth and total suspended solids (TSS) was highly correlated (R² = 0.94, p < 0.001) with non-algal light attenuation. The relations of Trophic State Index (TSI) indicated that phosphorus limitation was weak [TSI (Chl) - TSI (TP) < 0; TSI (SD) - TSI (Chl) > 0] and the effects of zooplankton grazing were also minor [TSI (Chl) - TSI (TP) > 0; TSI (SD) - TSI (Chl) > 0].

The physiological signals measured by Oriental Medicine instruments have been analyzed quantitatively in the view of the rule of promoting and counteracting relation of five evolutive phases theory. We tried to reduce the physiological signals measured by EAV(Elec-tro-Acupuncture according to Voll) and IR thermography to the representation of five evelutive phases. The EAV index and local skin temperature on acupuncture points of each phases measured and normalized so that the total value of five phases became unity. We assumed that the normalized EAV index and local skin temperature mean the deficiency or excess of Qi for each phases. The state of Qi distribution for each phases were approximately agree with the diagnostic pattern of O. M. doctor. Taking account of the Qi distribution state of·or the five evolutive phases, we performed a proper needle insertion on acupuncture points to induce the distinct change of Qi for each phases. We compared the measured results with the predictions of Qi variation by the rule of pro- moting and counteracting relation over the five evolutive phases. For all cases, the variation of Qi in the own phase on which a needle insertion was performed were exactly same to the theoretical prediction and partial agreement was shown for the other four phases. The same analysis was carried to the results of skin temperature measurements at accupoints. We found that the local skin temperature at accupoints of each phases shelved a finite change by the needle insertion and the behavior- of its change were strongly correlated to the rule of promoting and counteracting relation of five evolutive phases.

The purpose of the study was to explore the relationship among personality characteristics, hope and quality of life(QOL) of breast cancer patients. The subjects of the study were the 113 breast cancer patients treated at 3 university hospitals in Daegu and Busan from June 1 to Sep. 30, 2003. Personality characteristics was measured by using Personality Inventory(NEO-PI), hope measured by using Nowotny's Hope Scale, and QOL by using a questionnaire developed by Ro(1988). Data were analyzed with SPSS program by frequency, range, t-test, ANOVA, and Pearson correlation coefficients. The findings of this survey indicate 1) The mean personality characteristics item score was 2.64, hope was 2.78, and QOL was 3.19. It appeared that there was a slightly negative tendency about personality characteristics, hope and QOL of breast cancer patients. 2) There was a significant difference between personality characteristics, hope and QOL according to demographic factor. 3) There was a positive correlation between personality characteristics and hope(r=.49), hope and QOL(r=.377). Among subitem of hope and QOL especially confident, possibility of future, active participation, inner motivation and self esteem were positively correlated with personality characteristics especially extroversion, openness and conscientiousness. 4) There was a negative correlation between neuroticism and relation with neighbor(r=-.452), neuroticism and relation with family(r=-.344). It was found that personality characteristics, hope and QOL were essential concept for qualitive care of breast cancer patients and there were negative correlation with neuroticism toward relation with neighbor and relation with family. This study suggests that there would be further study to find out the importance and relationship among personality characteristics, hope and QOL of breast cancer patients.

The relationships between rice grain filling and air temperature of maturing period in paddy field were analyzed to evaluate the effects of climatic change on rice productivity in Korea. Data of air temperature of 31, 41 and 51 days after heading(DAH) for 11 years from 2002 to 2016 were collected and analyzed to determine the effects on rice yield and yield component related traits of Chucheogbyeo, popular cultivar in Gyeonggi province in Korea. As the results, ripening ratio was closely correlated with the mean of daily maximum temperature (DMAT $r=0.71^*$), the mean of daily temperature difference (DTD, $r=0.67^*$) of 41 DAH and DTD ($0.65^*$) of 51 DAH. Weight of 1,000 paddy rice grains was closely correlated with accumulated sunshine hours (ASH) of 31 ($r=0.84^{**}$), 41 ($r=0.75^{**}$), 51 ($r=0.72^*$) DAH. Brown rice grain weight recovery ratio was closely correlated with DTD ($r=0.76^{**}$) and ASH ($r=0.84^{**}$) of 31 DAH, DMAT ($r=0.75^{**}$, $r=0.79^{**}$), DTD ($r=0.79^{**}$, $r=0.77^{**}$) and ASH ($r=0.81^{**}$, $r=0.79^{**}$) of 41 and 51 DAH. Paddy rice yield was closely correlated with MDT ($r=-0.63^*$) of 31 DAH, mean of daily minimum temperature (DMIT, $r=-0.83^{**}$, $r=-0.70^*$), DTD ($r=0.71^*$, $r=0.62^*$) of 31 and 41 DAH. Brown rice yield was correlated closely with DMIT ($r=-0.86^{**}$, $r=-0.73^*$) and DTD ($r=0.80^{**}$, $r=0.72^*$) of 31, 41 DAH, and DTD ($r=0.69^*$) of 51 DAH. Milled rice yield was correlated closely with DMIT ($r=-86^{**}$, $r=-0.73^*$), DTD ($r=0.79^{**}$, $r=0.71^*$) of 31, 41 DAH, and DTD ($r=0.68^*$) of 51 DAH.

The purpose of this study was to investigate the relationship of time pressure, discretionary time, and subjective well-being(SWB) of university students. In order to achieve it, 493 university students(220 male, 232 female) completed a set of questionnaires about time pressure, discretionary time, subjective well-being. The t-test, multiple regression analysis were performed to analyze the data. The results are as follows. First, There were significant differences among the positive emotion, the negative emotion and time pressure. However, there was no statistically significant difference between the satisfaction of life and discretionary time according to gender. Second, time pressure was negatively correlated with the satisfaction of life of university students but positively correlated with the negative emotion. The discretionary time was positively correlated with the satisfaction of life of university students but negatively correlated with the negative emotion. Time pressure and discretionary time were not correlated with the positive emotion. Finally time pressure significantly correlated with the satisfaction of life, the negative emotion. And It seems that time pressure had an especially strong effect on the negative emotion. Such results imply that time pressure is important for reducing university students's the negative emotion, a subfactor of subjective wellbeing.
