According to the intercombined review of chemical and biological investigation it has been noted that the metabolizable energy per gram dietary protein of mixed diet of daily intake patterned by Korean population has been found 3.4-3.6 Cal., which entails 10-12% level of the protein calorie percentage of total metabolizable energy, the biological value being fallen within the scope 63-73. The structure of dietary protein has revealed that the lysine and isoleucine were primary limiting amino acids and threonine secondary limiting as a general trend, however, it is assumed that the ultimate nutritional effect of dietary protein might be restricted uniformly among regions by the amount of lysine, since the lysine availability has been yielded as low as 72-82% level. As for the net protein utillization NPUst falls in the range of 52-62 and the NPUop 47-58. In either part the mountainous region has demonstrated lowest value and the urban area highest, these trend being obviously associated with the ratio of animal protein relative to the vegetable origin. The net dietary protein calorie percentage (NDpCal %) has been found within the range of 5-7 that may be capable of meeting the requirement for the maintenance of adult, though for the growth it is insufficient. Present level of total caloric intake would not influence on the fate of protein value of prevailing regional diet in terms of caloric restriction, since the present intake of food energy is higher than the lower limit of caloric intake that would impair the biological performance of dietary protein fed ad libitum basis. Based on the protein efficiency, the adequacy of current level of protein intake was analyzed in terms of utilizable protein, and it has been demonstrated that the 37.8g of utilizable protein in the fishery region and 38.2g in the mountainous region were bellow the FAO recommendation. Accordin to the hematological study it may be interpreted that the anemic symptoms of the mountainous region has some possibility of being related to the inferior status of dietary protein in quality as well as in quantity.
We attempted to determine whether energy density would influence calorie intake via cognitive cues, as reflected by satiety. This experiment was designed using two different energy density levels of Kimbab: normal Kimbab (1.6 kcal/g) vs low-density Kimbab (1.0 kcal/g). 26 female college students participated in this study. The subjects ate Kimbab in the lab once a week for 2 weeks. Each week at noon, they were served 24 units of either normal or low-density Kimbab, and we determined the units, grams, and calories of the real & cognitive intake of Kimbab, and also analyzed the satiety rate after eating Kimbab. Our results demonstrated that the real calorie intake from the low-density Kimbab was significantly lower than that of the normal Kimbab (290.3 kcal vs 474.4 kcal, p<0.001), but we noted no significant differences in the units and grams of real and cognitive intake between the normal and low-density Kimbab. However, despite consuming 39% lower caloric intake, the subjects reported similar levels of satiety rates with the two different density levels of Kimbab, as they did not perceive themselves to have eaten more normal Kimbab than low-density Kimbab. Thus, this study provides evidence that the energy density of food is a crucial determinant of caloric intake, and supports the notion that the consumption of low energy-dense foods may result in a reduction of caloric intake without altering satiety.

The land treatment of sewage sludge is necessary because sewage sludge is increasing year by year. Therefore the research of sewage sludge solidification is underway as one of the land treatment methods. However, the problem with existing sewage sludge solidification is that the moisture content of sewage sludge is high and the dewaterability is low. Because of high drying cost the efficiency of energy production is low and the calorific value is insufficient. So the disposer is supplied with a filtration and caloric aid for improving dewaterability and calorific value. In this study, it is aimed to improve the fuel value of sewage sludge by confirming the feasibility of waste wood as a filtration and caloric aid. The dewaterability was measured by CST-test and the calorific value was measured by bomb calorimeter. As a result the dewaterability and calorific value are improved in all of the samples. The dewaterability was improved as the waste wood was added in the sewage sludge. By adjusting the waste wood adding rate into the sewage sludge the dewaterability and calorific value of sewage sludge will be improved. This study confirmed possibility of the waste wood used as filtration and caloric aid.

Background and Objectives: Dizzy patients with abnormal otolith function tests, despite a normal caloric response, are defined as having specific (isolated) otolith organ dysfunction. This study was performed to compare the differences in clinical presentation between isolated otolith dysfunction (iOD) patients with lab- and Sx-based iOD group and lab-based iOD symptoms. Subjects and Methods: The medical records of 23 iOD patients with normal caloric response but abnormal cervical vestibular evoked myogenic potential (VEMP), ocular VEMP, or subjective visual vertical were reviewed. Non-spinning vertigo was considered as otolith-related symptoms. The patients' age, onset of dizziness, Numeric Rating Scale on the severity of dizziness, and concomitant vestibular disorders were analyzed. Results: Patients in the lab-based iOD group were significantly older than those in the lab- and Sx-based iOD group. Known vestibular disorders were significantly more common in the lab-based iOD group (83.3%) compared to the lab- and Sx-based iOD group (18.2%). Despite the normal caloric response, catch-up saccade was found in the video head impulse test in more than half (54.5%) of the lab-based iOD group patients. There was no catch-up saccade in the lab- and Sx-based iOD group. There were no significant differences in gender ratio, frequency of dizziness attacks, and duration of illness. Conclusions: We propose new definitions of definite iOD (lab- and Sx-based iOD) and probable iOD (lab- or Sx-based iOD). These new definitions may help researchers to identify patients who are more likely to have true iOD, and facilitate comparisons of results between different studies.

Background: There are reports that food deprivation causes emphysematous changes in the lungs of rats and humans. However, the meaning of this phenomenon in patients with chronic obstructive pulmonary disease has not been evaluated. The aim of this study was to determine the correlations between the caloric intake and parameters of the lung function in patients with chronic obstructive pulmonary disease. Methods: Patients with chronic obstructive pulmonary disease who had visited the respiratory clinic from March, 2006 for one year were enrolled in this study. The patients underwent pulmonary function tests, and a dietitian evaluated their nutritional intake using a food record method. Results: There was no correlation between the total caloric intake and forced vital capacity (FVC, %predicted) or forced expiratory volume in one second ($FEV_1$, %predicted). The total caloric intake showed a positive correlation with the diffusing capacity of carbon monoxide (DLCO %predicted, DLCO/VA %predicted), and a negative correlation with the total lung capacity (TLC, %predicted). Of the calories taken, only calories from protein intake correlated with the diffusing capacity of carbon monoxide (DLCO %predicted, DLCO/VA %predicted). Conclusion: The total caloric intake of patients with chronic obstructive pulmonary disease showed a positive correlation with the diffusing capacity of the lung, and a negative correlation with the total lung capacity. Further study on the linkage between the caloric intake and severity of emphysema is needed.
To investigate the effects of crude protein and thyroxine on growth performance, nutrient utilizability, carcass composition, the content of total fat and cholesterol in leg muscle, breast muscle and liver, and caloric efficiency in broiler chicks. The experiment involved 3 levels of dietary crude protein (1-3 weeks: 20, 23, 26%; 4-6 weeks: 17, 20, 23%) and 3 levels of thyroxine (0.0, 1.5, 3.0 mg/kg). In the starting period (1-3 weeks), body weight gain of chicks fed diets containing 26% crude protein and 1.5 mg/kg thyroxine was higher than any other groups, and among thyroxine levels, 3.0 mg/kg thyroxine groups were lower. The best feed efficiency was obtained at 26% crude protein with no thyroxine supplemented or 1.5 mg/kg thyroxine supplemented groups. In the finishing period (4-6 weeks) the highest body weight gain was obtained at 23% crude protein with no thyroxine supplemented group. Feed intake of 17% crude protein with 1.5 mg/kg thyroxine supplemented group was higher than those of the other groups. It was found that the utilizability of crude protein in the starting period, showed the best utilizability at 20% crude protein with 1.5 mg/kg thyroxine group. Increasing crude protein level from 17 to 23%, utilizability of crude fat was decreased. The carcass composition was significantly (p<0.05) influenced by crude protein and thyroxine. Increasing thyroxine level from 0.0 to 3.0 mg/kg, crude protein content was increased whereas, crude fat content was decreased. Chicks fed diet containing 1.5 mg/kg thyroxine showed the lowest total fat content in liver tissue. In breast muscle, it was significantly (p<0.05) affected by crude protein and thyroxine. Present data revealed that the cholesterol content was increased for the chicks fed 3.0 mg/kg thyroxine. It the caloric efficiency, chicks fed a diet containing 20% crude protein with no thyroxine supplementation showed the highest caloric efficiency and the lowest efficiency was from 23% crude protein group with 1.5 mg/kg thyroxine. From this study it may be concluded that crude fat content of carcass could be successfully reduced by dietary supplementation of thyroxine, whereas crude protein content was increased.
Purpose: The purpose of this cross-sectional study was to assess the nutritional states and investigate the energy intake of tube-fed patients with severe neurodevelopmental disability. Methods: Eighty six tube-fed patients with severe neurodevelopmental disability were studied. Heights were measured by flexible scale segmentally. Nutritional parameters of weight, triceps skinfold thickness and mid-arm circumference were also measured. Total caloric intakes through the tube were calculated. Results: The anthropometric results showed that nutritional states of tube-fed patients with severe neurodevelopmental disability were poor. The mean daily caloric intake was much less than daily energy requirement (mean=45.2% of requirement). The caloric intake was 7.2 kcal/height (cm), 57.0 kcal/weight (kg). Height was more related with caloric intake (r=0.476) than weight (r=0.263). Conclusion: These results provide that tube-fed patients with severe neurodevelopmental disability were growth retarded and their energy intakes were much less than daily energy requirements. The preliminary evidence was that they need adequate nutritional supply.
Purpose: The study was done to develop an evidence-based enteral nutrition (EN) protocol for effective nutritional support for dysphagia in patients with acute stroke, and to evaluate effects of this protocol on clinical outcomes. Methods: A methodological study was used to develop the EN protocol and a quasi-experimental study to verify the effectiveness of the protocol. The preliminary EN protocol was drawn by selecting recommendations from previous well-designed EN guidelines, and then developing additional recommendations based on high-quality evidence. Content validation was assessed by an expert group, and clinical applicability by care providers and patients. The scale-level content validity index of the final EN protocol was 0.99. Assessment was done of differences in percentage of caloric goals achieved and presence of undernutrition, aspiration pneumonia, and gastrointestinal (GI) complications after application of the EN protocol. Results: In the EN protocol group, the percentage of caloric goals achieved ($R^2=.24$, p=.001) and the reduction of GI complications (p=.045) were significantly improved, but the presence of undernutrition (p=.296) and aspiration pneumonia (p=.601) did not differ from the usual care group. Conclusion: Results indicate that the new EN protocol for dysphagia in patients with acute stroke significantly increased their nutritional intake and reduced GI complications.
