Purpose: Chemotherapy-induced nausea and vomiting (CINV) can cause severe malnutrition. However, relationships between CINV levels, non-pharmacological coping methods, and nutritional status of female cancer patients have rarely been investigated. Therefore, this study aimed to analyze their relationships in gynecologic cancer patients. Methods: Participants receiving a highly and moderately emetogenic chemotherapy were recruited. The level of CINV was assessed using a numeric rating scale. Coping methods were determined using multiple-choice self-report questionnaires and categorized into seven types for statistical analysis. Nutritional status was evaluated using biochemical and anthropometric parameters. Results: Among all the 485 patients, 200 eligible inpatients were included. Despite the administration of prophylactic antiemetics, 157 patients (78.5%) still experienced CINV, and several used nonmedically recommended coping methods, such as just enduring the symptom or rejecting food intake. A total of 181 patients (90.5%) had nutritional disorders. Although the level of CINV was indirectly related to the occurrence of nutritional disorders, patients who rejected food (${\beta}=1.57$, p=.023) and did not use physical measures (${\beta}=-1.23$, p=.041) as coping methods were under the high risk of nutritional disorders. Conclusion: Korean gynecologic cancer patients had high levels of CINV and were at high risk of nutritional disorders, which may be related to the use of nonscientific coping methods, possibly due to cultural backgrounds and lack of proper nutritional program. Therefore, developing a culturally appropriate educational program for the cancer patients with CINV is urgently needed.

Protein-calories malnutrition is common among patients in the hospital. In particular, elderly patients with neurologic disorders has more risk of nutritional deficiency due to swallowing difficulty. Enteral tube feeding is more economical, physiological and immunological than parenteral nutrition for patients who have adequate gastrointestinal function. This study was conducted patients with neurologic disorders who received enteral nutrition at Asan Medical Center from February 1 to October 10, 2002. The control group (48 patients) were given traditional feeding methods 4 times a day while the treatment group (45 patients) were given improved feeding methods 3 times a day. We assessed nutritional status of patients and compared to both groups. We investigated body weight, serum albumin, hemoglobin, total lymphocyte count by means of nutrition markers. The objectives of this study is to reduce the time needed for nutritional requirement of patients without an increase in gastrointestinal intolerances. The results of this study are as follows: 1. Nutritional status of many patients in both groups were either malnourished or at risk for malnutrition. 2. The time to arrive to the nutritional requirements were 6.21 $\pm$ 0.35 days for the control group and 4.24 $\pm$ 0.52 days for the treatment group. The treatment group showed a significantly shorter amount of time. 3. The changes of the nutritional marker in the control group showed a significant drop in body weight, serum albumin and serum hemoglobin while the treatment group experienced a significant increase in body weight, serum albumin and total lymphocyte count. 4. Feeding intolerane such as diarrhea, high residual volume, ileus, nausea and vomiting were investigated. Diarrhea found in 25.1% (12 patients) of the control group and 22.2% (10 patients) of the treatment group and these findings are not significant.

Nutritional disorders are one of the most common diseases of crops and they often result in significant loss of agricultural output. Moreover, the imbalance of nutrition element not only affects plant phenotype but also threaten to the health of consumers when the concentrations above the certain threshold. A number of disease identification systems have been proposed in recent years. Either the time consuming or accuracy is difficult to meet current production management requirements. Moreover, most of the systems are hard to be extended, only detect a few kinds of common diseases with great difference. In view of the limitation of current approaches, this paper studies the effects of different trace elements on crops and establishes identification system. Specifically, we analysis and acquire eleven types of tomato nutritional disorders images. After that, we explore training and prediction effects and significances of super resolution of identification model. Then, we use pre-trained enhanced deep super-resolution network (EDSR) model to pre-processing dataset. Finally, we design and implement of diagnosis system based on deep learning. And the final results show that the average accuracy is 81.11% and the predicted time less than 0.01 second. Compared to existing methods, our solution achieves a high accuracy with much less consuming time. At the same time, the diagnosis system has good performance in expansibility and portability.

In patients with functional gastrointestinal disorders, dietary factors have an important effect on the development or worsening of gastrointestinal symptoms. Therefore, nutritional advice is often needed for the treatment of these patients. Although no firm conclusions can be drawn from current studies, the use of low-fat diets can be recommended in patients with functional dyspepsia. Constipation can be treated with a high-fiber diet. There are few studies in irritable bowel syndrome patients with diarrhea. The diet recommendations must be applied to each patient depending on symptoms.

Functional gastrointestinal disorders (FGIDs) such as infantile colic, constipation and colic occur in almost half of the infants. The aim of this paper is to provide a critical and updated review on the management of FGIDs and their impact on the health of the infant and family to health care physicians. Guidelines and expert recommendations were reviewed. FGIDs are a frequent cause of parental concern, impairment in quality of life of infants and relatives, and impose a financial burden to families, health care, and insurance. Therefore, primary management of the FGIDs should be focused on improving the infants' symptoms and quality of life of the family. If more than parental reassurance is needed, available evidence recommends nutritional advice as it is an effective strategy and most of the time devoid of adverse effects. The role of healthcare providers in reassuring parents and proposing the correct behavior and nutritional intervention by avoiding inappropriate use of medication, is essential in the management of FGIDs.

The purpose of this study was to analyze the association between self-reported voice problems and voice disorders in the Korean adult population. Data were collected from the 4th Korea National Health and Nutritional Examination Survey (2008) from 3,135 subjects (1,310 men and 1,825 women) aged 19 years and older. Multi-nominal logistic regression analyses were used to examine the association between self-reported voice problems and voice disorders in the Korean adult population. Adjusting for covariates (age, sex, education level, job, smoking, alcohol drinking, thyroid disorders, pain and discomfort during the last 2 weeks), self-reported voice problems included independently associated functional voice disorders (OR=4.70, 95% CI: 3.14-7.03) and organic voice disorders (OR=3.89, 95% CI: 1.57-9.65). The results of the present study verified that self-reported voice problems are valuable indicators for voice disorders. Further research is needed to ascertain the effect of self-reported voice problems on voice disorder in adults.

Accumulated data on medical care utilization among the insured in Korea Medical Insurance Corporation can explain the health status of the population. The purpose of this study was to analyze a change of the disease-mix and utilization pattern by controlling the size of the population enrollment. Major findings of the study are as follows : 1. The changes of inpatient disease-mix a. Utilization rate was 139.2% in 1988 against 1980. b. Disease groups higher than the average utilization rate included neoplasms, endocrine, nutritional and metabolic diseases and immunity disorders, mental disorders etc. Meanwhile, disease groups seen less often were infections and parasistic diseases, diseases of blood and bloodforming, diseases of the digestive system etc. c. Utilization rate was up 106.3% in 1988 compared to 1985, and diseases above that average level were ill-defined intestinal infections, chronic liver disease and cirrhosis, diabetes mellitus, essential hypertension, etc. d. The disease-mix by institution in 1988 compared to 1985 shows that chronic disorders rank high in general hospitals whereas opthalmologic, obstetric, and orthopedic diseases rank high in private clinics. 2. The changes of outpatient disease-mix a. Utilization rate was up 175.2% in 1988 compared to 1980. b. Disease groups higher than the average utilization rate included neoplasms, endocrine, nutritional and metabolic diseases and immunity disorders, mental disorders etc. And disease groups seen less often were infections and parasistic diseases, diseases of the respiratory system, diseases of the genitourinary system. etc. c. Utilization rate was up 104.0% in 1988 compared to 1985, and diseases above that average level were gastric ulcer, diseases of hard tissues of teeth, etc. And diseases seen below that average level were acute nasopharyngitis(common cold). acute upper respiratory infections of multiple or unspecified sites, etc. It was concluded that medical care utilization level was increased, and that, from 1980 to 1988, disease-mix shifted to the chronic disorders. Chronic disorders accounted for more medical care utilization in general hospitals.

Purpose: Food insecurity, which is the inability to obtain food or inadequate food consumption in terms of quality and quantity, has physical and psychological consequences on children's health. This study aimed to investigate the relationship between children's growth disorders and food insecurity in Qazvin city, Iran. Methods: A case-control study was conducted on 177 cases and 355 controls of children aged 3 to 6 years, who were referred to health centers in Qazvin city. The case group consisted of children with growth disorders. Data were obtained with the 18-item US Department of Agriculture questionnaire, a household socioeconomic questionnaire, a and growth monitoring card. The data were analyzed with using IBM SPSS Version 22.0, by independent sample t-test, chi-square test, and logistic regression. Results: A significant relationship was found between children's growth disorders and household food insecurity with (p<0.05, odds ratio [OR]=17.0, confidence interval [CI]=5.9, 48.8) and without hunger (p<0.05, OR=2.69, CI=1.4, 4.9). There were also significant relationships between children's growth disorders and socioeconomic status (p<0.05, OR=3.4, CI=1.4, 8.5), the duration of breastfeeding (p<0.05, OR=0.94, CI=0.9, 0.98), and children's ages (p<0.05, OR=0.94, CI=0.92, 0.96). Sex and birth order, and the age of the parents was not found to be significantly related with growth disorders. Conclusion: Lower socioeconomic status and household food insecurity were the important predictors of children's growth disorders. Policymakers should focus more on promoting steady employment and income among family members. Nutritional education for mothers is also recommended, in order to better meet the nutritional needs of the children.
