The purpose of the study was to investigate relationships among food safety training, knowledge, and practices of school food service employees. A questionnaire that identified employees' food safety training experience, knowledge, and practices was developed based on a review of literature. A total of 341 Korean school food service employees participated in the survey; the final usable responses were 293 (a response rate: 86%). Statistical analyses were conducted using SPSS for Windows (version 10). Most of the respondents (> 86%) took training sessions on 'proper hand washing' and 'proper food storage temperatures', whereas less than 60% had training on 'monitoring procedures and corrective actions at critical control points'. The mean score of their food safety knowledge was 8.02 out of 11. The majority of the employees knew correctly 'potentially hazardous foods (93.2%)' and 'diseases and symptoms with which they are excluded from working (87.0%)'; less than 50% chose a correct answer for 'sanitizing food contact surfaces.' A chi-square analysis revealed that the employees' actual knowledge did not differ significantly by whether they had food safety training (at the level of a =0.01), except one topic 'diseases and symptoms with which they are excluded from working.' Their self-reported practice scores were rated as 2.98 - 3.39 based on a 5-point Likert-type scale (1-not at all, 5-always). Employees' food safety training should be conducted continuously and repetitively to improve the effectiveness of the training.

In order to improve the quality of electricity in large scale power systems, stability of power system has to be achieved. This can be done by the means of preventative diagnosis of power equipments and protection, monitoring and control of the power system. Since the recent adoption of digital controllers, an improvement in stability was observed; in particular, IED, which contained self-diagnostic abilities such as fault tolerance, allowed for automatic recovery via redundancy or switching-over functions should there be faults with the equipments. Furthermore, communication lines have been hugely simplified, thus adding to the improvement in stability significantly. Taking these error reports and forecasting emergency reports and by effectively responding to them in the overiding controlling systems, high levels of system stability can be obtained. Power Management System that is being applied to automated power sub-stations, takes the IEC61850 international standard as its specification. In this paper, additional research into achieving stability of already developed PMS system and also the stability of the overall system was carried out, and the results of development of communication servers, which play a pivotal role in connecting systems, are stated.

Purpose: To investigate the relationship between headache and sleep by evaluating sleep quality, daytime sleepiness, and specific features related to sleep-disordered breathing (SDB). Methods: One hundred one subjects with headache and 118 healthy controls were enrolled. To collect various information on headache attacks, headache group completed self-reported questionnaire about the characteristics of headache attacks and the migraine disability assessment (MIDAS) questionnaire. The subjective quality of sleep was evaluated in all of the subjects using the Pittsburgh sleep quality index (PSQI) and Epworth sleepiness scale (ESS). In addition, the following specific features of sleep were evaluated in 28 subjects selected randomly from each group: apnea-hypopnea index (AHI), prevalence of SDB, nocturnal oxygen saturation (SaO2), and oxygen desaturation index (ODI) as measured using a portable monitoring device. Results: The global PSQI and the prevalence of poor sleeping (global PSQI >5), ESS scores and the prevalence of daytime sleepiness (ESS score >10) were significantly higher in the headache group (both p<0.0001, respectively). The mean scores on the numerical rating scale and the MIDAS were significantly higher in the poor-sleeper group than in the good-sleeper group (p=0.0347 and p=0.0016, respectively). The global PQSI and prevalence of daytime sleepiness were significantly higher in the chronic-headache group than in the acute-headache group (p=0.0003 and p=0.0312, respectively). Conclusions: There is a significant association between headache and sleep. Especially, severity and chronicity of headache were significantly associated with sleep quality and daytime sleepiness.

Objectives : Symptoms of attention-deficit hyperactivity disorder (ADHD) during childhood may persist into adulthood. This study included the development and validation process of the Korean Adult ADHD Rating Scale (K-AARS), which was developed for screening and monitoring treatment of adults with ADHD. Methods : Preliminary questionnaires of the K-AARS were based on the reviews of previous adult ADHD scales and clinical experiences of the board certified child and adolescent psychiatrists in Korea. For this study, 136 adults (18-50 years old) with inattention, hyperactivity and/or impulsivity symptoms were enrolled as ADHD subjects, and compared with 406 control subjects (18-50 years old) without ADHD symptoms. Construct validity was examined using explorative factor analysis and Cronbach's alpha to obtain internal reliability coefficients. Concurrent validity was evaluated by comparison with the Conners' Adult ADHD Rating Scale (CAARS). Results : An explorative factor analysis showed that the K-AARS had 8 factors (inattention, hyperactivity, impulsivity, antisocial personality disorder/conduct disorder/oppositional defiant disorder, impairment, driving, emotional dysregulation, disorganization). K-AARS was highly reliable in terms of internal consistency (Cronbach's alpha 0.77-0.95) and correlation between factors (0.57-0.86). Concurrent validity with the CAARS and discriminant validity were statistically significant. Conclusion : The K-AARS is a valid and reliable measure for assessment of Korean adults with ADHD.

Purpose: The aim of this study was to examine the effect of Desexualization Care guided by dramaturgical interaction on women's embarrassment during cervical cancer screening. Method: This study was carried out in a nonequivalent control group non-synchronized post-test only design. 62 women who had cervical cancer screening were' conveniently recruited from a university hospital health promotion center. Embarrassment was measured under four distinctive sub-dimensions by the method of self-reported questionnaire and blood pressure and pulse rates monitoring. The data of control group had a conventional pap smear were collected in advance and then those of experimental group were gathered after completing data collection in the control group. Women in experimental group were provided with a newly developed cervical cancer screening programme in which interdisciplinary team conducted dramaturgical interaction. Result: There was no significant difference in the scores of VAS between the two groups. The score of physiological response of Embarrassment Measurement Scale was significantly lower in experimental group than in the control group (p <.05), while no significant difference was found in cognitive-emotional, non-verbal and verbal behavioral responses between the two groups. There was also no significant difference in blood pressure and pulse rates between the two groups during cervical s creening. Conclus ion: Desexualization Care guided by dramaturgical interaction during cervical screening was found to have positive effect on physiological response of women's embarrassment. Further research for identifying other main variables which might have influenced on women's embarrassment is needed.

This study evaluated the Skin Whitening effects of 'fermented-C.' for Atrium cosmetics using a single-arm clinical trial. Twenty female adults (mean age 42.1 ± 6.6 year) were enrolled, all participants used this cosmetic product on their face for 4 weeks. The change of brightness (L-value) was measured by spectrophotometer while subjective assessments were also obtained to find the participants opinions on whitening and their general satisfaction measured by a 5-point scale (5 for very satisfactory, 5 for satisfactory, 3 for moderate, 2 for unsatisfactory, 1 for very unsatisfactory). The participants were also questioned about any adverse effects by filling out a self-monitoring report. The average L-value increased from 62.55 ± 2.14 on day 0 to 63.22 ± 1.96 after 4 weeks corresponding to a 1.1% brightness improvement (p < 0.01). The average scores for subjective whitening and general satisfaction were better than moderate with scores of 3.6 ± 0.5 and 3.7 ± 0.7, respectively. No notable complaints were reported regarding any kind of adverse effects such as erythema, itching or burning. The clinical data collected in this study supports that fermented-C. from Atrium cosmetics has whitening potential in a safe Functional Cosmetics package.

Purpose: This study was conducted to monitor the development of Korean premature infant at six-month age and to explore factors related to developmental status of the premature infants. Methods: Participants were 58 premature infants whose corrected age was six-months old and their mothers. The developmental states of infants were followed-up with the Korean Prescreening Developmental Questionnaire (KPDQ-II). Clinical characteristics of the infants were identified from the medical records. Other characteristics including Edinburgh Postnatal Depression Scale, husband's support, social support, and mother-infant attachment were assessed using self-report questionnaires from the mothers. Results: Forty three percent of the infants were in the group of questionable status of development on the KPDQ-II. There were significant differences between the premature infants with normal developmental status and those with questionable developmental status depending on gender ($x^2$=5.03, p=.034), gestational age (t=2.59, p=.012), hospital stay (p=.013), revised Neurobiologic Risk Score (p=.005) and mother-infant attachment score (t=2.12, p=.040). Conclusion: Mother-infant attachment, as well as physiological state of premature infants, is an important variable in early development. Therefore, early monitoring for the development has to be done for physiologically vulnerable premature groups. Also, providing proper nursing support to improve maternal attachment needs to be considered.
