This study was conducted to investigate quality attributes which could affect foodservic satisfaction by the year (2005, 2008, 2011) and dining area (classroom vs. dining hall) in order to find ways to improve school lunch service and foodservice satisfaction of middle school students. The numbers of those surveyed were 1,103 students in 2005, 1,917 students in 2008, and 1,921 students in 2011. Overall foodservice satisfaction was significantly increased gradually in dining hall food service: 3.29 +/- 1.21 in 2005, 3.45 +/- 1.00 in 2008, 3.94 +/- 0.98 in 2011. In classroom food service, overall foodservice satisfaction was not significantly different between in 2005 (3.09 +/- 0.97) and in 2008 (2.98 +/- 1.02), but it was significantly increased in 2011 (4.05 +/- 1.00). Stepwise multiple regression analysis showed that overall foodservice satisfaction was most affected by the taste of food. The importance of 11 quality attributes except food sanitation and gathering feedback on school meals was significantly increased in 2011 compared with 2005. Food sanitation among 13 attributes was most important attribute in 2005 and 2011. The numbers of quality attributes affecting students' overall foodservice satisfaction were 5 to 7 by year, those attributes were almost identical with attributes which students thought importantly. Therefore, in order to increase the overall foodservice satisfaction of the school lunch service continually, it is recommended to identify the quality attributes that are important to students, and to check their levels of performance in order to overcome their differences.

This Study was carried out to investigate dietary life and recognition of diet related factors in elemantary, middle and high school students. This study was surveyed by questionnaires and data were analyzed by SPSS program. Comparative analysis was conducted according to three school student groups(elementary childrens, middle school students, high school students). The subjects were 1,886 school students(female 893, male 959) of 51 schools in nationalwide region. The Distribution of subjects was elementary school childrens 544, middle school students 661 and high school students 681. The results are summarized as follows. Only Sixty percent of the subjects had breakfast regularly. About one forth of the subjects had the habit of skipping breakfast or eating 2-3 times per week. Pricipal reasons of skipping breakfast were 'busy'(50.7%) and 'not delicious or poor appetite'(31.0%). Regularity of having breakfast and reasions of skipping breakfast were significant differences according to school student groups(p<0.001 respectively). About half of the subjects didn't have sufficient amounts in breakfast. Most subjects(92.1%) had lunch regularly by virtue of school lunch service. One forth of the subjects had dinner irregularly. Pricipal reasons of skipping dinner were 'not delicious'(41.7%), 'busy'(15.1%) and 'weight loss'(14.3%). Regularity of having dinner and reasons of skipping dinner were significant differences according to school student groups(p<0.01, p<0.001 respectively). The most delicious meal was dinner in 56.7% of the subjects and lunch in 37.1% of the subjects. There was significant difference in recognition of most delicious meal according to school student groups(p<0.001). Only ten percent of the subjects thought that nutrition education was not needed. Diettitian was recognized as nutrition educator in sixty percent of the subjects. Only 5 percent of the subject recognized teacher as nutrition educator. There were not significant differences in most delicious meal and nutrition educator according to operation type of school lunch service. The findings suggested continuous attention and guidance for healthy dietary life and necessity of nutrition education for both school students and their parents.

This study was carried out to identify factors related to breakfasts in elementary, middle and high school students. This study was surveyed by questionnaires and data was analyzed by SPSS program. Exploratory analysis was conducted according to three school student groups (elementary children, middle school students, and high school students). The subjects were 1,886 school students (female 893, male 959) of 51 schools in the nationwide region. The distribution of subjects was elementary school children 544, middle school students 661 and high school students 681. The results are summarized as follows. Only sixty percent of the subjects had breakfast regularly. About one fourth of the subjects had the habit of skipping breakfast or eating it 2~3 times per week. Frequency of having breakfast and reasions of skipping breakfast were significantly different according to school student groups (p < 0.001 respectively). The rate of skipping breakfast was 14.4% in elementary school, 16.1% in middle school, and 25.0% in high school. The main reason for skipping breakfast was "not delicious or poor appetite" in elementary school (42.5%), but "busy" in middle (50.2%) and high school (61.1%). There was no significant difference in frequency of having breakfast according to living areas (rural and urban). There were not significant differences between frequency of having breakfast and BMI and degree of satisfaction on body weight. But there were significant difference in frequency of having breakfast according to economical status (p < 0.05). There were significant differences in degree of school performance according to frequency of having breakfast (p < 0.001). There was significant relationship between the time of attending school and the frequency of having breakfast. But there were significant relationships between frequency of having breakfast and time of rising. These findings suggested that the time of rising was controlled by having enough time that students eat breakfast. And mother (or person who prepares meals) must have more concerns about preparing breakfast for children and students.

This study was designed to analyze and compare production management practices and labor productivity between conventional and commissary school foodservices and 46 dietitians of commissary school foodservices in Kyunggi-do. The response rates were 89.7% and 91.3%, respectively. The number of meals served was ranged from less than 100 to over 1,900 in conventional school foodservices and from 200 to 1,600 in commissary foodservices. Thirty three conventional foodservices(42.3%) produced less than 300 meals per day. Numbers of satellite school per central kitchen were ranged from 1 to 5 schools ; fifty percent of commissary foodservices have contained 3 satellite schools. Meals for satellite schools were transported between 11:00 a.m.and 12:00 a.m ; transportation time was from 10 to 90 minutes. Waiting time before service in satellite schools was between 10 minutes and 80 minutes. Part time employees supported by parents were hired in 37.3% of conventional and 50% of commissary school foodservices. Voluntary workers were supplied for 64.9% of conventional and 52.4% of commissary school foodservices. Labor productivity was calculated from work schedule. Labor productivity(labor minutes per meal)was lowest in foodservices with 101-4-- meals(8.48 min)was lower than that of foodservices with above 401 meals ; no significant differences were found among 401-700(6.02 min), 701-1,100(4.01 min), 1,101-1,500(3.41 min), and 1,501-1,900(3.15 min)meals in conventional foodservices. Labor minutes per meal of foodservices which served less than 400 meals(6.90 min) per day was significantly lower than those of foodservices which served 401-1,900 meal(3.41-4.92 min) in commissary foodservices(p<0.05)

The Na⁺/H⁺ exchanger-1 (NHE-1) is a ubiquitously expressed pH-regulatory membrane protein that functions in the brain, heart, and other organs. It is increased by intracellular acidosis through the interaction of intracellular H⁺ with an allosteric modifier site in the transport domain. In the previous study, we reported that glutamate-induced NHE-1 phosphorylation mediated by activation of protein kinase C-β (PKC-β) in cultured neuron cells via extracellular signal-regulated kinases (ERK)/p90 ribosomal s6 kinases (p90RSK) pathway results in NHE-1 activation. However, whether glutamate stimulates NHE-1 activity solely by the allosteric mechanism remains elusive. Cultured primary cortical neuronal cells were subjected to intracellular acidosis by exposure to 100 μM glutamate or 20 mM NH₄Cl. After the desired duration of intracellular acidosis, the phosphorylation and activation of PKC-β, ERK1/2 and p90RSK were determined by Western blotting. We investigated whether the duration of intracellular acidosis is controlled by glutamate exposure time. The NHE-1 activation increased while intracellular acidosis sustained for >3 min. To determine if sustained intracellular acidosis induced NHE-1 phosphorylation, we examined phosphorylation of NHE-1 induced by intracellular acidosis by transient exposure to NH₄Cl. Sustained intracellular acidosis led to activation and phosphorylation of NHE-1. In addition, sustained intracellular acidosis also activated the PKC-β, ERK1/2, and p90RSK in neuronal cells. We conclude that glutamate stimulates NHE-1 activity through sustained intracellular acidosis, which mediates NHE-1 phosphorylation regulated by PKC-β/ERK1/2/p90RSK pathway in neuronal cells.

Rapid eye movement (REM) sleep has an essential role in the process of learning and memory in the hippocampus. It has been reported that linalool, a major component of Lavandula angustifolia, has antioxidant, anti-inflammatory, and neuroprotective effects, along with other effects. However, the effect of linalool on the cognitive impairment and behavioral alterations that are induced by REM-sleep deprivation has not yet been elucidated. Several studies have reported that REM-sleep deprivation-induced memory deficits provide a well-known model of behavioral alterations. In the present study, we examined whether linalool elicited an anti-stress effect, reversing the behavioral alterations observed following REM-sleep deprivation in mice. Furthermore, we investigated the underlying mechanism of the effect of linalool. Spatial memory and learning memory were assessed through Y maze and passive avoidance tests, respectively, and the forced swimming test was used to evaluate anti-stress activity. The mechanisms through which linalool improves memory loss and behavioral alterations in sleep-deprived mice appeared to be through an increase in the serotonin levels. Linalool significantly ameliorated the spatial and learning memory deficits, and stress activity observed in sleep-deprived animals. Moreover, linalool led to serotonin release, and cortisol level reduction. Our findings suggest that linalool has beneficial effects on the memory loss and behavioral alterations induced by REM-sleep deprivation through the regulation of serotonin levels.

Purpose: A case of a huge ethmoid sinus and orbital cyst causing ocular deviation initially diagnosed as a mucocele-like cyst and after orbitotomy eventually discovered to be a naso-orbital encephalocele is described.Case summary: A 5-year-old male with no previous medical history presented with a palpable mass in the medial canthus area with left exodeviation of the left eye. His best-corrected visual acuity was 20/25 in the right eye and 6/12 in the left eye with limitation of motion of -4 at adduction in the left eye. Brain magnetic resonance imaging scans revealed a 3.0 × 2.5 × 2.5 cm-sized cystic mass suspected as a mucocele or nasolacrimal duct cyst invading the orbital space. The cyst was removed using a Lynch and caruncle incision, and intracystic fluid was aspirated. During the excision, a small defect of the skull base was detected with cerebrospinal fluid (CSF) leakage and leaking point of dura was sealed. His pathologic result was disorganized glial and fibrous tissue, consistent with encephalocele. Three days later, CSF leakage recurred. On postoperative day 8, duroplasty was performed. A one month later, his best-corrected visual acuity was 6/12 in the left eye with orthotropic eye position. Limitation of motion was improved to -1 at adduction with enophthalmos. No other complications were detected. Conclusions Congenital naso-orbital encephalocele invading the orbit is rare. However, a cystic mass in the sinuses involving the orbit should be considered, rendering thorough physical and radiologic examinations including computed tomography scans necessary to look for bone defects.

The purposes of this study were to investigate the importance level on factors affecting the foodservice management contract perceived by the salespersons in the foodservice company. To get the data on the perceived importance level on the affecting the foodservice management contract, the questionnaires were developed by the delphi technique and modified by the pilot test. The questionnaires consisted of 4 categories and 19 items on the factors affecting the foodservice management contract and the importance level on the factors were measured by 5-likert scale. From March 12 to April 13 in 2003, the self-administrative questionnaires were mailed to the 60 salespersons. The questionnaires were responded from the 48 salespersons(respondent rate : 77 %). As a result, the salesperson' perceived importance level of 'the sales ability' was higher than those of the other categories in the private contract and the salesperson' perceived importance level of 'the evaluation of the foodservice company' was higher than those of the other categories in the competitive bid. The importance of the 'the evaluation of the foodservice company' between the private contract and the competitive bid was significantly different(p<.05), and the importance of 'the sales ability' of the competitive bid was significantly higher than that of the private contract(p<.001).
