Purpose : Surveying the rates, severity, and variables influencing depression and their correlation between pain and depression in Korean cancer patients, we attempted to provide a basic database for the effective depression management program. Methods : The results of survey were colleted from 10 patients who were hospitalized at Seoul National University Hospital for cancer treatment from February to June of 1999. Factors of depression and the level of pain were examined by self-reported survey employing Korean version of Beck Depression Inventory(BDI) and an abridged version of Brief pain Inventory respectively. The purpose of this study and guidelines for the questionnaires were clearly explained to participating patients by Resgitered Nurses before answering the survey. Demographic and clinical characteristics of patients were compiled by reviewing their medical records in corporation with a family physician. The difference in the level of depression among patient groups was analyzed with the t-test and ANOVA, and the correlation between variables with Pearson correlation coefficient. Results : 1) 142 subjects comprised 79 male and 63 female, and their mean age was 51.86. 2) The mean scores of the worst pain for last 24-hours was 6.08(SD 2.23), the average pain for last 24-hours 4.44(SD 1.85), and the mean scores of pain at the time of survey 3.48(SD 2.25), while the mean scores of the least pain for last 24-hours 2.25(SD 1.83). 3) The mean BDI scores were 23.73(SD 0.99), and 55.6% of patients were evaluated to be in depression(cutting point 21). Scores of depression for cancer patients were higher than normal population. 4) The correlation between worst pain for last 24-hours and depression(r=0.252, P=0.002), average pain for last 24-hours and depression(r=0.225, P=0.007), present pain and depression(r=0.291, P=0.000) were significant. 5) Significant differences were found among groups of cancer patients with pain with respect to gender(t=3.59, p=0.000), level of education(F=4.063, P=0.009), ECOG(F=3.352, P=0.021). There was significant positive correlation between depression and pain(r=0.171, P=0.042). Conclusions : More than 50% of cancer patients with pain are suffering from depression. We have shown that the variables like the degree of pain, gender, level of education, ECOG, and age are significantly related to the depression in cancer patients. The findings of this study may be used for assessing high-risk patients in need of intervention and for planning effective therapeutic strategies for them after the routine assessment. Further study is necessary to investigate the cultural differences and the variables influencing on depression in Korean cancer patients.

Population dynamics of greenhouse whitefly, Trialeurodes vaporariorum (Westwood), were modeled and simulated to compare the temperature effects of air and tomato leaf inside greenhouse using DYMEX model simulator (pre-programed module based simulation program developed by CSIRO, Australia). The DYMEX model simulator consisted of temperature dependent development and oviposition modules. The normalized cumulative frequency distributions of the developmental period for immature and oviposition frequency rate and survival rate for adult of greenhouse whitefly were fitted to two-parameter Weibull function. Leaf temperature on reversed side of cherry tomato leafs (Lycopersicon esculentum cv. Koko) was monitored according to three tomato plant positions (top, > 1.6 m above the ground level; middle, 0.9 - 1.2 m; bottom, 0.3 - 0.5 m) using an infrared temperature gun. Air temperature was monitored at same three positions using a Hobo self-contained temperature logger. The leaf temperatures from three plant positions were described as a function of the air temperatures with 3-parameter exponential and sigmoidal models. Data sets of observed air temperature and predicted leaf temperatures were prepared, and incorporated into the DYMEX simulator to compare the effects of air and leaf temperature on population dynamics of greenhouse whitefly. The number of greenhouse whitefly immatures was counted by visual inspection in three tomato plant positions to verify the performance of DYMEX simulation in cherry tomato greenhouse where air and leaf temperatures were monitored. The egg stage of greenhouse whitefly was not counted due to its small size. A significant positive correlation between the observed and the predicted numbers of immature and adults were found when the leaf temperatures were incorporated into DYMEX simulation, but no significant correlation was observed with the air temperatures. This study demonstrated that the population dynamics of greenhouse whitefly was affected greatly by the leaf temperatures, rather than air temperatures, and thus the leaf surface temperature should be considered for management of greenhouse whitefly in cherry tomato grown in greenhouses.

Purpose: The aim of this study was to investigate children's eating behaviors and teachers' feeding practices during mealtime at child-care centers. In addition, it focused on the difference of teachers' feeding practices on children age under 2 years ( ${\leq}2$ years old) and 3 years and older (3~5 years old). Methods: A total of 169 teachers working at childcare centers in Geumcheon-gu, Seoul, Korea, completed self-report questionnaires in December 2013. The questionnaires were composed of questions on children's eating behaviors, feeding practices; 'Explain', 'Praise', 'Modeling', 'Indulgent', 'Insist' and 'Reward', interaction with home, and a range of demographic information (analysis rate: 51.2%). Results: Approximately 59.2% of teachers had not taken a class on feeding practice and the average score for nutrition knowledge was 14.6 out of 30 points. The most undesirable eating behavior of children during mealtime was 'eating while walking around (36.7%)' both ' ${\leq}2$ years old' and '3~5 years old'. Regarding feeding practices according to children's undesirable eating behaviors during mealtime, there were differences between age groups. When children did not eat all of the foods that were served and did not clean up silverware or seats after having food, teachers caring for '3~5 years old' practiced 'Explain'. However, percentages of those who practiced 'Indulgent' and 'Modeling' were significantly higher in teachers caring for ' ${\leq}2$ years old' than '3~5 years old'. Conclusion: These findings indicated that teachers caring for children lack education and knowledge about nutrition and feeding practice. In addition, verbal feeding practices, like explain, were mainly used by teachers. As a result, for teachers, guidelines and programs for learning about age appropriate feeding practice during mealtime at child-care centers may be needed.

Purpose: Regardless of treatment, brain metastases are associated with a poor prognosis. We aimed to investigate the clinical characteristics of cancer patients with brain mestastases they after admission into a hospice unit and knowing they have received appropriate hospice and palliative care. Methods: We retrospectively reviewed the medical records in 40 cancer patients with brain metastases they after admission into a hospice unit from March in 2003 to March in 2005. Results: There were 20 males (50%) and 20 females (50%), and the median age of the patients was 64 years. The most common cause of brain metastases was lung cancer (22 patients, 55%), followed by stomach cancer (5, 13%) and breast cancer (3, 8%). Sixteen patients (40%) have never been teated and 20 patient have received the chemotherapy for the primary cancer. The most common symptom of cancer patients with brain metastases is headache (12 patients, 30%), followed by mental change (10, 25%), focal weakness (9, 23%) and convulsion (4, 10%). The most prevalent cause for admission was mental change (13 patients, 33%), followed by pain (9 patients, 23%). The reasons for hospice and palliative care were through recommendation of physician (1 patient, 3%), patient and family self (14, 35%) and the others (25, 62%). Twenty five of the others has been referred to hospice and palliative care during conservative management after referral and enrolled at hospice unit. The median hospitalization was 19 days and median survival in hospice and palliative care was 41 days. The median survival was 87 days from the day when the cancer patients have been diagnosed as brain metastases to death. Conclusion: The duration of hospice and palliative care was not enough to care the cancer patients with brain metastases. We suggest physicians, patients and family need the education and promotion for effective hospice and palliative care.

Objectives : The purpose of this study was to investigate the various aspects of stress in patients with chronic prostatitis. Methods : Thirty two chronic prostatitis patients meeting the criteria of NIH-category III were compared with sixty four controls. Data pertaining to the source of, response to, and coping with stress, as well as chronic prostatitis symptom index were collected using a self-report questionnaire. The questionnaire consisted of a Global Assessment of Recent Stress(GARS), Stress Response Inventory(SRI), Ways of Coping Checklist(WCC), in addition to the NIH-CPSI. Results : From the results of GARS subscales, the scores of changes in relationship, sickness or injury and financial were significantly higher in patients with chronic prostatitis than normal controls. Chronic prostatitis patients had greater amplification of somatization, depression and anger in SRI and significantly lower score in ways of coping checklist compared with controls. In the NIH-CPSI of chronic prostatitis patients, the degree of symptom played a role in depression as stress response item and significant negative correlationship between the symptom point and problem focused, seeking social support coping strategy was observed. Conclusion : These results show that patients with chronic prostatitis have greater stress, higher stress response and insufficient coping strategy. Therefore, these efforts should be considered that enhancing healthier coping strategy and evaluation and management of stress experienced by chronic protatitis patients

Purpose: The purpose of the study was to identify the nutrition knowledge, dietary attitudes of guardians, and nutritional status of infants and toddlers as well as the relationships between these variables. Methods: The participants were selected among applicants for low-income family financing provided by the government and included 115 infants and toddlers as well as their guardians. Demographic data, nutrition knowledge, dietary attitudes, and nutrition intakes were assessed using a self-administered questionnaire, biochemical examination, and 24 Hour-Recall method. Results: The score for guardians' nutrition knowledge was 12.97 points of a possible 15, and the score for dietary attitudes was 53.38 points of a possible 75. The nutrition knowledge and dietary attitudes showed significant differences by education level (p < 0.05) and family structure (p < 0.05). Energy intakes of subjects aged 6 ~ 24 months and over 25 months were lower than the DRI for Koreans. The intakes of carbohydrates, protein, and fat of subjects aged 6 ~ 24 months and over 25 months showed no significant differences by level of nutrition knowledge or dietary attitudes. The intake of Ca of subjects aged over 12 months showed significant differences by level of nutrition knowledge (p < 0.05). The intakes of Thiamin of subjects aged 6 ~ 11 months and P of subjects aged over 12 months showed significant differences by level of dietary attitudes (p < 0.05). There was a small positive correlation between education level and nutrition knowledge as well as between dietary attitudes. Nutrition knowledge showed a positive correlation with dietary attitudes. There was a positive correlation between nutrition knowledge and Ca, Riboflavin, as well as Vit C levels. Conclusion: Therefore, it is necessary to consider an educational program for increasing the practical application of knowledge to nutrition management for improvement of nutrition intake in infants and toddlers.

Purpose: This study aimed to investigate the current status of food service management in elementary care classes. Methods: A focus group interview with seven care class managers and a survey with 101 care class managers using a self-administered questionnaire in Gyeonggi province were conducted. Results: In the focus group interview, purchased meals and snacks were evaluated as low quality by the care class managers. Frequent use of frozen or processed food and products with low prices were also reported as problems. Care class managers were in charge of meal and snack planning without any guidelines or expert advices. The results of the survey show that most schools serve purchased snacks and meals. The average unit costs of one meal and snack were 4,062 and 1,463 Won, respectively. The average unit costs of snacks during semester (p = 0.015) and vacation (p = 0.039) were significantly lower in rural than urban areas. The percentages of schools that prepared nutrition standards for meal and snack planning in elementary care classes were only 7.4% and 10.9%, respectively. The meal menus were mostly provided by catering service companies, and the snack menus were planned mostly by the care class managers. Menu planning by the care class managers was more usual in rural than urban areas (p = 0.054 for meal planning and p = 0.008 for snack planning). Just 33.7% of schools introduced safety standards for food service in elementary care classes, and more than half of the respondents (56.4%) did not do a regular medical check-up. Only 33.7% of the respondents received education for food safety. Conclusion: These results show the necessity for establishment of detailed guidelines for food service in elementary care classes and for the introduction of a food safety and nutrition education program customized for care class managers.

Purpose: Screening of preschool-age children for nutrition programs to improve dietary intake and behaviors requires cost-effective and easily administered validated assessment tools. The purpose of this study was to develop a parent/caregiver-administered instrument for measuring diet quality and behaviors of preschoolers as a nutrition quotient for preschoolers (NQ-P). Methods: Development of NQ-P was carried out in three steps: item generation, item reduction, and validation. The 24-h dietary record was selected as the gold standard reference tool. The 38 items of the NQ-P checklist were derived from a systematic literature review, expert in-depth interviews, statistical analysis of the fifth Korean National Health and Nutrition Examination Survey data, and national nutrition policies and recommendations. Self-administered questionnaires were delivered to parents who recorded 24-h dietary intakes of 100 responders aged 3~5 yr. Pearson's correlation was used to measure the level of agreement between questionnaires. Item reduction was performed, and 20 items were selected based on survey results, expert reviews, and priorities of national nutrition policy and recommendations. The 412 nationwide subjects sampled through daycare centers completed the 20-item checklist questionnaire. The construct validity of the NQ-P was assessed using confirmatory factor analysis, LISREL. Results: After analyses of exploratory factors, NQ-P items identified three dimensions of diet (balance, moderation, and environment). The three-factor structure accounted for 49.28% of the total variance. Standardized path coefficients were used as weights of the items. The NQ-P and three-factor scores of the subjects were calculated by the obtained weights of the questionnaire items. Conclusion: A food behavior checklist for preschoolers' NQ would be a useful and suitable instrument for evaluating nutrition adequacy and dietary quality of Korean preschoolers.

The purpose of this study is to provide basic data regarding effective learning opportunities in childbirth education classes. Also analysis of the data indicates the optimum conditions for the welfare and improvements in the promotion of health in childbearing mothers. The results of this study are as follows; 1) The average age of the subjects in this study was 30.6 years and the total number of subjects was 58 pregnant women. The average number of children was one and 84.5% of the subjects were unemployed even though 63.8% of them held over bachelor's degrees. It was found that 22.4% of the subjects were living in an extended family. Also 61.5% of them were living with parents-in-law. The number of pregnancies were calssified as one, two, or three to nine times with the percentages of 58.7%, 22.4% and 18.9%, respectively. Further, 72.4% of the subjects had no abortion experience and 15.5% had one aborion experience. While 89.7% of the subjects planned to feed their babies with breastmilk, mixed feeding were used by only 22.4% of the sample. These data were collected at about 6 months after delivery. Thus one can see that a low rate of breastfeeding was common. 2) The length of one period of childbirth education is four weeks. It was found that 36.2% of the subjects participated in childbirth education only once, where as 13.8% participated four times and 19% of the subjects participated in this class more than four times. pregnant at least once. Further, 75.9% of the participants were participated in this education through their own will. Their motivation for participation developed through information, advertisement and posters which contained information on childbirth education. Those with unplanned pregnancies 92.9% participated after a suggestion by the nurses. The number of participants in terms of percentage according to the childbirth education contents can be classified as following. The most active participation was shown in preparation of delivery(77.6%), postpartrm management(56.9%) fetal development(37.6%) and physiology of pregnancy(17.2%). It was found that 75.9% of the subjects were willing to participate again if they were given a chance. The reason can be summarized as following: The content of the education is very helpful(47.7%). Scientific knowledge can be obtained through this program(20.5%). Participation helps in achieving psychological stability(9.1%). Participation enables one to establish a friendly relationship with other participants(6.8%) of the sample. 24.1% of the participants did not want to participate again. The reasons can be as following: They do not want another baby(42.9%). The first paricipation in childbirth education gave enough knowledge about childbirth(21.4%). Another reason for not want to participate again was because they had a cesarean birth(14.3%). Only 7.1% of them responded with a negative view. A response that they do not need childbirth education after their operation can be traced back to the general belief that childbirth education is the place where one prepares for natural birth through the Lamaze breathing technique. Of the subjects, 91.4% suggested that this program could be recommended to other childbearing mothers, because this program gave educational content along with psychological stability for childbearing women. Of the subjects 41.4% did not see any efforts towards the welfare of the baby, where as 88.2% did. Among the subjects 58.6% made some effort to eliminate the discomfort of labor by breathing and imagination and breathing and walking. Further 41.7% of the 24 subjects did not do anything toward the welfare of the baby, because they did have a cesarean section so that they didn't have a chance even though they had been educated about childbirth. Also 33.3% of the subjects did not do anything toward the welfare of the baby, because they lacked a willingness. After leaving the hospital, only 75.9% of the subjects did some exercises. The subjects who tried participate this program with their husband accounted for 20.7% of the sample. Interviewing with the subjects solved some of the uneasiness and. fear of delivery, increased self-confidence in parenting and active coping in the delivery process.
