The aims of this research were to examine the effect of heating temperature (65, 75, and $85^{\circ}C$) and $CaCl_2$ concentration level (3, 4, and 5 mM) on the physicochemical properties of ${\beta}$-lactoglobulin (${\beta}$-lg) nanoemulsions (NEs) and to study how the droplet size of NEs affects the bioaccessibility (BA) of coenzyme $Q_{10}$ ($CoQ_{10}$). The droplet size of NEs and BA of $CoQ_{10}$ was assessed by particle size analyzer and UV-Vis spectrophotometer, respectively. An increase in heating temperature and $CaCl_2$ concentration level resulted in a significant (p<0.05) increase in the droplet size of NEs while there were no significant differences in polydispersity index and zeta-potential of NEs. When NEs containing $CoQ_{10}$ were incubated in simulated small intestinal phases, an increase in the droplet size and polydispersity index of NEs was observed. This indicated that NEs were not stable in small intestine and digestion of NEs occurred. As heating temperature and $CaCl_2$ concentration level were decreased, a significant (p<0.05) increase in BA of $CoQ_{10}$ was observed. There was a significant (p<0.05) increase in BA of $CoQ_{10}$ with a decrease in the droplet size of NEs. In conclusion, heating temperature and $CaCl_2$ concentration level were key-parameters affecting the initial droplet size of NEs and BA of $CoQ_{10}$ was negatively correlated with initial droplet size of NEs.

Objectives : The aim of study was to examine the prevalence of night eating syndrome(NES) and its correlates in schizophrenic outpatients. Methods : The 14 items of self-reported night eating questionnaire(NEQ) was administered to 201 schizophrenic patients in psychiatric outpatient clinic. We examined demographic and clinical characteristics, body mass index(BMI), subjective measures of mood, sleep, binge eating, and weight-related quality of life using Beck's Depression Inventory(BDI), Pittsburgh Sleep Quality Index(PSQI), Binge Eating Scale(BES) and Korean version of Obesity-Related Quality of Life Scale(KOQoL), respectively. Results : The prevalence of night eaters in schizophrenic outpatients was 10.4%(21 of 201). Comparisons between NES group and non-NES group revealed no significant differences in sociodemographic characteristics, clinical status and BMI. Compared to non-NES, patients with NES reported significantly greater depressed mood and sleep disturbance, more binge eating pattern, and decreased weight-related quality of life. While 'morning anorexia' and 'delayed morning meal'(2 of 5 NES core components in NEQ) were not differed between groups, 'nocturnal ingestions', 'evening hyperphagia', and 'mood/sleep' were more impaired in NES group. Conclusions : These findings are the first to describe the prevalence and its correlates of night eaters in schizophrenic outpatients. These results suggest that NES has negative mental health implications, although it was not associated with obesity. Further study to generalize these results is required.

Objectives : The aim of this study is to evaluate the clinical characteristics of night eating syndrome(NES) in bipolar disorder outpatients. Methods : The 14 items of self-reported night eating questionnaire(NEQ) was administered to 84 bipolar patients in psychiatric outpatient clinic. We examined demographic and clinical characteristics, body mass index(BMI), subjective measures of mood, sleep, binge eating & weight-related quality of life using Beck's Depression Inventory (BDI), Pittsburgh Sleep Quality Index(PSQI), Binge Eating Scale(BES) and Korean version of Obesity-Related Quality of Life Scale(KOQoL), respectively. Results : The prevalence of night eating syndrome in bipolar outpatients was 14.3%(12 of 84). Comparisons between NES group and non-NES group revealed no significant differences in demographic characteristics, BMI and clinical status except economic status and comorbid medical illnesses. However, compared to non-NES, patients with NES was more likely to have binge eating pattern and poorer weight-related quality of life. Conclusions : This study is to be the first to describe the clinical correlates of night eaters in bipolar outpatients. Although there were few significant correlates of NES in bipolar outpatients, relatively high prevalence of NES suggest that clinicians should be aware to assess the patients with bipolar disorder on NES, regardless of obesity status of patients.

The study aims to answer two questions: (a) what perceptions do NNESTs have about teaching native English speaking (NES) students? (b) what perceptions do NES students have of their NNESTs? The study participants were four NNESTs and 17 NES students. Data were collected through one-on-one interviews, which were analyzed qualitatively. Major study findings showed the differences between the NNESTs and their NES students in the area of teaching and language performance. The NNESTs were perceived by their students as using ineffective teaching techniques, lacking in their command of English, especially accent; the NNESTs, in turn, perceived themselves as well-prepared teachers with not too much concern about nonnativeness of English, and felt that their students were not actively engaged in their class. The present study indicates, for both NNESTs and NES students, the need to be aware of World Englishes (WE) in terms of language and pedagogy. This involves the variety of Englishes, especially with different accents existence among nonnative speakers, and the variety of learning and teaching methods in English class, where both need to create a balance between the old and new perspective to maintain a middle ground.

To verify the newly developed decision assisting expert system for nitrogen fertilizer application NES to Illinois cornfields, a couple of N rate studies from Dr. Howard and five Illinois Agricultural Experiment Stations were applied. Four types of recommendations including the current Illinois recommendation, Hoeft recommendation, NES, and maximum economic recommendation were compared with each other for the crop yields, profits, recovery rate, and N losses to cornfields. The N rate of NES recommendation, considering productivity index (PI), soil organic matter content (SOM), and pre-sidedressing nitrate concentration (PSNT) level, was the lowest in comparison to those of other recommendations. However, N recovery rate in NES was generally higher and the resulting N loss was lower than others. But, adherence to the recommendations may also reduce farmers income if environmental expense did not considered. Therefore, NES will be more effective by adding the factors including environmental expense, tillage systems, crop rotation, and other agricultural management parameters.

N fertilizer recommendations to optimize with consideration to maximum crop yields, maximum profits, and minimum N losses to ground or runoff water, an advisory system. Nitrogen Expert System (NES), was developed. The system was to estimate the optimal rate of N fertilizer application cornfields in Illinois. NES was constructed using Smart Elements, a knowledge-based system that manages the expertise of human experts. NES was reinforced by addition of the effect of a productivity index (PI), soil organic matter content (SOM), and pre-sidedressing of nitrate concentration (PSNT) to the optimal N fertilizer recommendation. NES contains 49 rules, 1 class, 14 objects, and 2 properties. NES was successfully operated, showing N recommendations with inputs of three soil properties including PI, SOM, and PSNT. NES can reduce N loss to the environment, but adherence to the recommendations may also reduce farmers income. Therefore, NES will be more effective by evaluating both environmental damage assessment and other economic agricultural management parameters and other soil physico-chemical parameters.

The several floor finishing materials that widely used in entertainment service industry buildings were evaluated according to the method of NES 713. Also, toxic gases of floor finishing materials in combustion without air flow rate were checked as concentration of fire gases variation according to time using gas analyzer. We had estimated the smoke hazard of floor finishing materials in fire. As results of gas analyses using the method of NES 713, toxic index of samples was estimated range of 2～9.7. Therefore, a large amount of toxic gases will release from a floor finishing materials fire and connoted great smoke hazard in fire.

There are accumulating evidences suggesting that connexin (Cx), a gap junction channel-forming protein, acts as a growth suppressor in various cancer cells, and this effect is attributeed to the gap junction-mediated intercellular communication (GJIC). In order to characterize the relationship between the growth-arresting activity of Cx26 and its cytoplasmic localizations after expression, we linked a nuclear export signal (NES) sequence to Cx26 cDNA before transfecting into a rat breast cancer cell line. A confocal fluorescent microscopic observation revealed that the insertion of NES minimized the nuclear expression of Cx26, and increased its cytoplasmic expression, including plasma membrane junctions. Total cell counting and BrdUrd-labeling experiments showed that the growth of the breast cancer cells was inhibited by 74% upon transfection of Cx26-NES, whereas only 9% inhibition was observed with only Cx26 cDNA.
