Objectives : The purpose of this study is to investigate the minor stress in daily life related to undergoing hemodialysis and the relationship between minor stresses, coping skills, and subjective quality of life among the patients with end stage renal disease. Methods : Seventy seven patients on hemodialysis were enrolled in this study. Minor stress was assessed with daily stress inventory-Korean version(K-DSI), ways of coping checklist identified the use of the following coping strategies:problem-focused, seek social support, emotion-focused coping and wishful thinking. Socio-demographic data were obtained and World Health Organization-Quality of Life Scale(brief form) was also administered to subjects. Results : Participants mean age was $55.92{\pm}13.71$ years. The mean of the event, impact and impact/event (I/E) ratio scores of K-DSI were $29.06{\pm}21.57$, $88.69{\pm}75.88$ and $2.92{\pm}1.11$, respectively. These scores were much higher than normative data of K-DSI. Among the 5 categories of this inventory, the scores of cognitive stressors were highest. 5 categories of the inventory showed positive relationship with way of coping subscales, which showed coefficient of correlation between 0.259(p<.01) and 0.495(p<.001). However, no significant correlation was found between minor stress subscales and quality of life. Hemodialysis patients in our study used more emotional-focused coping methods, which was considered as passive way of cope than problem-orientated coping methods. Conclusion : The main findings of this study indicated that patients on hemodialysis showed higher level of perceived minor stress than normal population. The patients treated with hemodialysis tend to use passive way of coping primarily. For assessing the stress in patients on hemodialysis, clinician has to consider both level of perceived minor stress and the ways of coping the patients primarily use.
Purpose: This study identified the relationship between dietary habits and health-related behaviors depending on the Big Five personality factors (extraversion, openness, agreeableness, conscientiousness, neuroticism). Methods: The NEO-II test was administered to 337 male and female college students in Seongnam City, Gyeonggi Province, and their dietary habits and health-related behaviors were surveyed. Results: The male participants showed higher scores for extraversion, openness, agreeableness, and conscientiousness compared to that of their female counterparts, while the female participants showed higher scores for neuroticism. As for the results of multivariate logistic regression analysis, in the case of men, higher scores for extraversion were related to a lower intake of instant/fast foods and a higher intake of vegetables; higher agreeableness scores were related to a lower intake of fruit; and higher neuroticism scores were related to a heavy intake of high-cholesterol foods. It was found that higher openness scores were associated with a higher intake of burnt fish/meat and a lower intake of animal fat, while higher agreeableness scores were related to a lower intake of burnt fish/meat in women. Also, those subjects with higher openness and agreeableness scores were found to better consider the nutritional balance when having a meal. In the case of the male participants, higher openness scores were related to increased physical activity, while higher neuroticism scores were related to increased smoking and a lack of sleep. As for the women, those with higher extraversion scores smoked more, while those who recorded higher agreeableness scores were involved in more physical activities. Conclusion: Differences were observed in dietary habits and health-related behaviors between men and women depending on personality factors, and the analysis results of some dietary habits according to personality factors were inconsistent with those of the overseas studies. Therefore, to provide customized nutritional counseling when considering each individual's personality factors, more research results from domestic samples should be collected and accumulated.

We investigated elementary students' conceptions of the simple electric circuit using a battery, a bulb and a wire, and made comparison between the cognitive conflict through peer discussion and the cognitive conflict through physical experience. Two hundred and sixty-four sixth grade students who already had learned about the electric circuit were participated. The questionnaire to investigate the student's conceptions about simple electric circuit consisted of 5 items drawing the wire connections between a battery and a bulb to light the bulb. The students in the discussion group paired randomly with student who had different conceptions, and then each pairs discussed about their ideas freely with each other. After discussion they conducted CCLT(Cognitive Conflict Level Test) which consisted of 4 factors; recognition, interest, anxiety, reappraisal. The physical experience group conducted a task in which they connected a battery and a bulb with a wire, then conducted CCLT. The sixth graders had various misconceptions. Most students were not aware of the scope of negative battery terminal and two electric terminals of a bulb. Many students emphasized the tip of a bulb and positive battery terminal. The score of CCLT in the discussion group was higher than in the physical experience group. This results showed that discussion with peers was more effective than physical experience to arouse cognitive conflict.
The purpose of this study was to compare the effect of several reheating treatments (immersing the package into hot water, heating the soup in the pot and convection ovens after taking out of the opened package. heating the soup package in microwave) on the sensory characteristics of cook-chill and sous-vide spinach soup. Sensory evaluations were made on 5 sensory attributes by a 12-member panel using quantitative descriptive analysis(QDA). The fresh cooked spinach soup had a significantly(p<0.01) higher score in color than the reheated sous-vide one. The latter, however, had a significantly(p<0.05) higher score in taste than the former. Overall acceptability of the sous-vide spinach soup was not different from that of fresh cooked one, which supports the potential of the product in foodservice operation for the efficient management of meal plan. Reheating treatments didn't show any differences in taste, flavor, color, texture, appearance and overall acceptability. Therefore, any reheating treatment nay be used for cook-chill and sous-vide spinach soup.
Soil pollution indices (SPI) were designed for estimating quality of soil polluted with arsenic and heavy metals. Applying the quality reference value of soil based on its multifunctional purpose was a key step. For considereing multifunctions of soil, soil was classified into 4 groups-agricultural land, residential area, recreational area, factorial site. Then, each concentration of arsenic and each of five heavy metals (Cd, Cu, Hg, Pb, Zn) in soils grouped was transformed to a mathematical value based on the soil quality reference value which may stand for ecological impact. Soil pollution score (SPS) was the addition of the 6 values transformed, and the range of the SPS was divided into 4 Soil Pollution Classes (SPC). The SPC 1, 2, 3, and 4 were SPS <100, SPS 100-200, SPS >200-300, and SPS >300, repectively. SPS and SPC were evaluated with the results of the data from employing the Soil Network of 1994. Based on the soil quality reference values, SPS and SPC of the Soil Network's data were transformed and classified, respectively. Then, SPS and SPC were compared with arsenic and the 5 heavy metal contents of their reference values resulted from the Soil Network's. From this method, soil quality of most of the Soil Network area was estimated to be healthy. However, ca. 3.0~4.0% of the Soil Network area was determined in a range of slightly and heavily polluted. As the mean value of SPS of the Soil Network's was 66.2 which indicates most of soil evaluated was healthy. When the SPSs of the data were divided into 4 groups of SPC, Class 1 (Good quality of soil), Class 2 (Need to be checked area 1), Class 3 (Need to be checked area 2) and Class 4 (Polluted area) were 87.0, 9.4, 2.4, 1.2%, respectively. Using SPI were comparable to those of heavy metal contents in soils, and would be comprehenve to determine the status of soil qulity. Methodology of the developing SPI would be applicable to the other soil pollutants such as organic and inorganics than arsenic and 5 heavy metals used here.

Background: Chronic paranasal sinusitis is one of the most common disease in the otorhinolaryngologic field. Endoscopic sinus surgery is treatment of choice in chronic paranasal sinusitis. The aim of this study was to evaluate objective and subjective treatment outcomes of endoscopic sinus surgery in adult chronic paranasal sinusitis with or without polyp. Materials and Methods: We reviewed 84 adult patients underwent endoscopic sinus surgery by one surgeon from June 1999 to June 2000, prospectively. We analyzed preoperative and postoperative subjective symptom scores and acoustic rhinometric results. Results: Fifty cases were male and thirty four cases female. The average age was of 33 year-old (range: 17 to 66 years). There was significantly improvement of symptom scores in postoperative 3 months and 6 months compared with preoperative symptom scores. There was significantly increased postoperative total volume of nasal cavity. When we compared high score group with low score group, there was statistically significant improvement of symptom scores between preoperative stage and postoperative 3 months in radiologic grading group. Conclusions: Endoscopic sinus surgery is considered to be effective for the treatment of chronic paranasal sinusitis. It seems to be helpful to employ subjective symptom score system and objective total volume change of nasal cavity through acoustic rhinometric test to analyze effectiveness of endoscopic sinus surgery. In this study, the most important preoperative factor of sinus surgery outcomes is radiologic grading system.

Purpose: The purpose of this study was to determine whether the dietary quality of food consumed by the elderly is influenced by the consumption of healthy functional foods using Nutrition Quotients for the Elderly (NQ-E). Methods: The study subjects were 250 adults aged ≥ 65 living in Seoul or Gyeonggi-do. Those who had consumed healthy functional food for more than 2 weeks within the previous year were classified as healthy functional food consumers, and the quality of their meals was evaluated using the NQ-E. Statistical analysis was performed using SAS 9.4, and sex and age-associated differences were adjusted before comparing differences based on healthy functional food intake. Results: The average age of the study subjects was 70.8. The scores for each area and the Nutrition Quotient (NQ) score were as follows: balance 43.3 points, moderation 56.7 points, practice 65.7 points, and NQ 52.5 points. When comparing differences according to healthy functional food intake status, healthy functional food consumers had significantly higher balance and NQ scores than non-consumers. When considering each NQ item score, healthy functional food consumers had significantly higher scores than non-consumers for fruit, fish and seafood, eggs, nuts, and whole grain rice, and a higher score for effort to maintain a healthy diet. Conclusion: Dietary quality as assessed by Nutrition Quotients for the Elderly was better for healthy functional food consumers than non-consumers.
Purpose: The goal is to identify the effectiveness of the IKDC subjective score in the clinical outcome study after reconstruction of the anterior cruciate ligament. Materials and Methods: Twenty-four patients after ACL reconstructions using twelve hamstring autografts and twelve Achilles allografts were evaluated. Lysholm knee score, IKDC subjective score, Knee Outcome Survey score and Tegner activity score were evaluated for the subjective outcome value. Static instability tests, Biodex dynamometer and one-legged hop for distance tests were done for the objective outcome value. Three functional performance tests (FPTs) including Carioca test, Shuttle run test and Co-contraction test were performed for deciding the final results. Each scale was compared with FPTs results and Pearson's correlation test was used to test the correlation between the parameters. Results: IKDC subjective score, single hop test, and quadriceps power in low velocity of Biodex dynamometer tests had a positive correlation with the total FPTs results. Conclusion: IKDC subjective score can be an effective test to evaluate the functional status as well as the subjective outcome after ACL reconstruction.
This study evaluated the usefulness of the elasticity score and strain ratio in the differential diagnosis of benign and malignant nodules in thyroid elastography. We performed a retrospective analysis based on the results of fine needle aspiration cytology. The Chi-square test and the Mann-Whitney U test were used to analyze the difference between the five degrees of elasticity score and strain ratio according to the benign and malignant thyroid nodules. ROC curve analysis was used to determine the elasticity score and the best cut-off value of the strain ratio for the prediction of malignant nodules. There was a statistically significant difference (p=0.000) between the homogeneity of the elasticity score and the difference of the strain ratio between the benign and malignant nodule groups. On the ROC curve analysis, the elasticity score and the srain ratio for predicting benign and malignant nodules were determined as AUC 0.842, 0.700, cut-off value 3, 2.49 (p=0.001). Therefore, the elasticity score and strain ratio may be useful in the differential diagnosis of thyroid nodules.

Objectives: The purpose of this investigation was to study the health status of apartment guards and associated factors. Materials and Methods: This investigation was conducted for 1 month starting from August, 1997. Study population in this cross-sectional survey consisted of 182 guards of apartments located throughout the district of Taegu. Each subject completed a questionnaire about his general characteristics, health behaviors, job descriptions, subjective GIT symptoms and somatization and depression using Symptom Checklist-90-Reversion (SCL-90-R) by self administrated questionnaire and personal interview. Results: Study subjects had one or more GIT symptoms(53.3%), somatization symptoms(83.5%) and depression symptoms(79.7%). The mean scores of GIT, somatization and depression symptoms were not different among the age groups and based on marital status, respectively, but, significantly different by education level(p<0.05). The mean scores of GIT, somatization and depression symptoms were not different among the age group and based on marital status, respectively, but, significantly different by regular diet and by the subject's health status(p<0.05). The mean scores of GIT, somatization and depression symptoms were not different by duration of shift work, by job tenure and by the number of managed houses but, those of somatization and depression symptoms were significantly different by level of job satisfaction(p<0.05). Conclusion: The health statuses of guards at apartments were different from other shift workers because of healthy worker effects and characteristics of their jobs.
