This study aimed to find the differences in weight control status and eating behavior of satisfied and dissatisfied female high school students regarding their own body shape. The participants consisted of 238 students at two female high schools in Nonsan-si, Chungnam-do in May of 2008. Self-assessment evaluated present body shape and ideal body shape they would like to have by providing silhouette drawings. The subjects were divided into two groups, 'satisfied' and 'dissatisfied', according to the differences between present body shape and ideal body shape. In the distribution of subjects according to body mass index, 100% of overweight, 97.0% of normal weight and 48.7% of underweight belonged to the dissatisfied group. There were significant differences in weight control and eating behavior between dissatisfied and satisfied groups in terms of frequency and reasons of conducting weight control behavior, body weight return after weight reduction, skipping breakfast and consuming fast food. The satisfied group was two times more likely to not conduct weight control behaviors compared to the dissatisfied group. The main reason for trying to control weight differed according to the group; the reason was feeling fat in the dissatisfied group and desiring to be healthy in the satisfied group. The percentage of subjects that returned to their original weights after weight reduction was 5 times higher in the dissatisfied group. The percentages of subjects that regularly skip breakfast and consume fast food were both higher in the dissatisfied group than in the satisfied group. The dissatisfied group responded 'eating alone' more frequently among nine binge eating behaviors compared to the satisfied group. Both groups, however, did not show any difference in overeating of meals, eating speed, intake frequency of regular meals, food preference, preferred cooking method, carbonated beverage intake and snack eating behavior. In summary, the dissatisfied group tried more unnecessary body weight reduction and had poor eating behavior. Accordingly, to correct the biased perception of body shape by the majority of female high school students, the values of our society should change toward the pursuit of beauty of health.

The aim of this study was to assess effects of aromatherapy on anxiety and depression of caregivers for patients in rehabilitation therapy and to provide basic data for the aromatherapy. Beck Anxiety Inventory(BAI) and Beck Depression Inventory(BDI) for the preliminary assessment of anxiety and depressive mood were administered to caregivers for patients in rehabilitation therapy in Chungbuk National University Hospital. Forty two out of seventy subjects who got scores above 10 in BDI were selected. Forty two Participants were divided into orange group, lavender group and control group. They had got the aromatherapy by using the lamp diffusion method for 4 weeks. Only forty participants completed a trial. Effects of the aromatherapy were measured using BAI, Hamilton Anxiety Rating Scale(HAM-A), BDI, Hamilton Depression Rating Scale(HAM-D), Self Esteem Scale(SES) and Index of Wellbeing(IOWB) before and after the aromatherapy. Orange group showed significant difference in the change of BDI scores compared with control group. Lavender group showed significant difference in the mean change of BAI, BDI and IOWB scores compared with control group. These results suggested that aromatherapy with orange oil was effective for depression and the aromatherapy with lavender oil was effective for anxiety as well as depression.

Small high-resolution Earth observation satellites require precise optical alignment at the submicron level. However, misalignments can occur due to the influence of external factors during the launch and operation despite the sufficient alignment processes that take place before the launch. Thus, satellites need to realign their optical elements in orbit in what is known as a refocusing process to compensate for any misalignments. Refocusing algorithms developed for satellites have only considered de-space, which is the most sensitive factor with respect to image quality. However, the existing algorithms can cause correction error when inner and external forces generate tilt amount in an optical system. The present work suggests an improved online refocusing algorithm by considering the tilting effect for application in the case of a de-spaced and tilted optical system. In addition, the algorithm is considered to be efficient in terms of time and cost because it is designed to be used as an online method that does not require ground communication.

Purpose: The purpose of this study was to elucidate the effects of spiritual nursing intervention on spiritual well-being and depression level of the hospice patients. Method: The subjects for this study were collected from 62 patients who were admitted in the hospice care unit from July 28, 2002 to October 31, 2002 in D city K hospital. Subjects were 31 members of the experimental group and 31 members of the control group. It was devised with a nonequivalent control group pretest-posttest design. The spiritual nursing intervention was given by using the therapeutic use of self, Scripture, prayer, Hymn and music, use of church community involvement and refer to pastors according to assessment of patients' spiritual need for 3 weeks(total 12 times and 1 hour per each intervention). Sangsoon Choi(1990) and Jungho Kang(1996)'s spiritual well-being scale, which was modified from Palautzian and Ellison(1982)'s spiritual well-being scale, was used to investigate patients' spiritual well-being. To investigate level of depression, OkHyun Song(1977)'s Depression Scale, which was modified from Zung(1965)'s Depression Inventory, was used. Data were analyzed by x2-test, t-test, Repeated measures ANOVA with SPSS/Win 10.0 program. Results: 1.The 1st hypothesis, 'total spiritual well-being score in the experimental group, who received the spiritual nursing intervention, will be higher than the control group who did not receive the spiritual nursing intervention' was supported(F=6.28, p=0.015, Interaction: p=0.000). 2.The 1-1st sub-hypothesis, 'religious well-being score in the experimental group, who received the spiritual nursing intervention, will be higher than the control group who did not receive the spiritual nursing intervention' was supported(F=12.75, p=0.001, Interaction: p=0.000). 3.The 1-2nd sub-hypothesis, 'existential well-being score in the experimental group, who received the spiritual nursing intervention, will be higher than the control group who did not receive the spiritual nursing intervention' was supported(F=6.87, p=0.016, Interaction: p=0.000). 4.The 2nd hypothesis, 'depression level in the experimental group, who received the spiritual nursing intervention, will be lower than the control group who did not receive the spiritual nursing intervention' was supported(F=10.45, p=0.002, Interaction: p=0.000). Conclusion: From the above results, spiritual nursing intervention was an effective program to improve spiritual well-being state and decrease depression level for the hospice patients. In the future, when the spiritual intervention, which the researcher developed, applied on nursing field, the hospice patients can have comprehensive well being including spiritual well being and peaceful dying life.

This study was conducted to evaluate and compare new beer (NB) with market beers, e.g., New castle brown ale (NC), Victoria bitter (VB), and Coopers pale ale (CP) using physicochemical parameters. In addition, pattern recognition analyses were carried out using an electronic nose based on mass spectrometry (MS-E nose) and an electronic tongue (E-tongue) for differentiation of the different types of beer. The measured alcohol content of NB was 4.37%. NB was not significantly different compared with other types of beer with regard to bitterness unit, color, and polyphenol content (p<0.05). On the basis of the flavor pattern determined by the MS-E nose, NB was separated by DF1 (first score from discriminant function analysis), while NC, VB, and CP were located in the same group. The result of the E-tongue showed that the different samples could be clearly discriminated; NB was less sour. It was suggested that the discriminant function analysis (DFA) given by the MS-E nose and E-tongue could be used for evaluations during new product development. Furthermore, because of its simplicity, it might be possible to use the validated method for the evaluation of beer.

Background and Objectives : Voice disorders can cause problems in patients with benign vocal cord lesions emotionally, physically, economically and functionally. Neither subjective nor objective voice examinations can evaluate such factors adequately. The Voice Handicap Index (VHI) subjectively evaluates voice disorders in terms of physical, functional, emotional factors and measures the patient's perception of the impact of voice disorder. The purpose of this study is to evaluate the usefulness of VHI in the patients with benign vocal cord lesions. Materials and Method : The authors evaluated 37 patients who experienced laryngeal microsurgery for benign vocal cord lesions from september 2003 to August 2004. The VHI was used to measure the postoperative changes of the patient's perception and acoustic analysis and aerodynamic tests were also done. Statistical analysis was done using paired t-test and Pearson's correlation. Results : The VHI scores showed statistically significant reductions postoperatively. In acoustic analysis, jitter and shimmer had statistically significant reductions after surgery but noise-to-harmonics ratio did not. A statistically significant change in the average MFR and MPT perioperatively was found. The relationship between VHI and acoustic, aerodynamic analysis attained statistical significance. Conclusion : The VHI is a useful assessment tool to monitor the patient's self-perception of voice change after the surgery of benign vocal cord lesions. The VHI measurement, when combined with acoustic and aerodynamic analyses, will be helpful in comparing functional outcomes after voice surgery.

This case study examined mathematics anxiety of a public high school sophomore who was unable to perform well in mathematics but later overcame his fear of mathematics. In this study, he showed high levels of mathematics anxiety in the assessment tools that evaluate mathematical anxiety factors. Cognitive and behavior treatments were carried out to alleviate his anxiety. First, cognitive treatments that were implemented include: understanding his own problems, writing down his thoughts on a record sheet, and changing intermediate and core beliefs. This paper explored cognitive and affective changes and reactions during the treatment process. Second, behavioral treatments that were conducted include: the divided-page method and peer tutoring. The divided-page technique involves the test subject to write down and solve his problems on a note to see what kind of cognitive and affective changes occur during the process. This paper also explored how Su-chul, an overly competitive student, changed and reacted cognitively and affectively through peer tutoring. The results revealed that Su-chul's exam anxiety, as well as other factors, has decreased. Moreover, he regained his self-confidence by solving math problems that he had felt difficult. His competitive attitude also has turned into a cooperative and thoughtful one.

The purpose of this study was to investigate consumption of health functional food (HFF) and dietary habits, nutrient intake, and dietary quality by HFF consumption in college students. The subjects of this study included 283 college students (179 males and 104 females) in Incheon metropolitan city. The cross-sectional study was conducted using self-reported questionnaires, including kinds of HFF consumed, motivation for purchase, reason for consumption, effect after consumption, reason for no consumption, and dietary habits. A three-day recall method was used for dietary assessment. Dietary qualities were assessed using nutrient adequacy ratio (NAR), mean adequacy ratio (MAR), and nutrient density (ND) values. The percentage of HFF consumption was 40.2% in males and 50.0% in females. The main kinds of HFF consumed by males were vitamins and minerals, red ginseng, protein, and omega-3 fatty acid, in that order. HFF consumed by females were vitamins and minerals, red ginseng, omega-3 fatty acid, and individually approved functional ingredients, in that order. The main motivation for purchase of HFF was recommendation of family and relatives (males 76.4% and females 78.8%). The main reason for consumption of HFF was health promotion (males 67.7% and females 63.5%) and the main reason for no consumption of HFF was not having a health problem (males 49.5% and females 46.2%). The dietary habit score for 'eat the milk or dairy product everyday' (p < 0.05) in females was significantly higher in HFF consumers, compared to HFF non-consumers. In males, the ND of vitamin B1 (p < 0.05) in HFF consumers was significantly higher compared to HFF non-consumers. In females, HFF consumers showed a significantly higher ND of vitamin B2 (p < 0.05) and Ca (p < 0.01), compared to HFF non-consumers. Regardless of HFF consumption, the NAR of vitamin C, folic acid, and Ca was less than 0.7. These results suggest the need for nutrition education for college students in order to improve dietary habits and for balanced nutritional status, and to provide correct information on HFF.
