  • Purpose: This study examined the status of food allergy management and importance-performance analysis (IPA) between elementary, and middle and high school employees in school foodservice. Methods: The participants were employees in elementary (n = 171) and middle and high schools (n = 187) in the Jeonbuk area. The demographic characteristics, the status of food allergy management, food allergy education, and the importance and performance status were assessed using a self-administered questionnaire. Results: Approximately 55.0% of employees in elementary and 32.6% in middle and high schools recognized that the foods in menu tables induced allergies. Approximately 93.0% of employees in elementary and 85.0% in middle and high school thought that food allergy management was an important part of school foodservice because of the possibility of health emergencies. Elimination and replacement meals were provided more in middle and high schools than in elementary schools. Food allergy education from nutrition teachers had been given to 62.6% of employees in elementary and 50.3% in middle and high schools. To prevent food allergy accidents, 72.4% of employees in elementary schools and 65.2% in middle and high schools wanted more accurate information on students with food allergies. As a result of IPA, elementary, middle, and high school employees were aware of the importance and performed well: 'Strict control of allergy-inducing foods because of cross-contamination'. On the other hand, they were not aware of the importance and performed them insufficiently: 'Know how to use epinephrine to prepare for emergencies'. Conclusion: Therefore, it is necessary to improve the consciousness of nutrition teachers for the effective application of food allergy education, especially the recognition of allergy-inducing foods and emergency responsive ability.

  • This study aimed to develop a creative education class program using metaphor, one of the creative thinking techniques, and to examine the effectiveness of the program targeting for randomly sampled 338 students in six middle schools. The creative education class program with the metaphor was developed based on content elements concerning 'astronomy' in 2015 science curriculum revision in South Korea. The program was tested for validity after being modified and supplemented three times by forming a group of experts, and the final version of the program was applied to school education fields during four periods, including block time. To find out the effectiveness of the program and the implementation, creative education class satisfaction test and creative thinking process test were conducted. That is to say, the creative education class satisfaction test was conducted before treatment and the creative thinking process test was implemented both before and after treatment. The results of the study are as follows. First, in this study, the program was developed with the emphasis on students voluntarily and actively participating in creative education programs while utilizing creative thinking methods. Second, the statistical results of the pre- and post-class about the creative education program using the metaphor of creative thinking techniques represented significant results(p<.05). In other words, the two-dependent samples by students' pre-and post-score about the creative education class showed significant statistical test results (p<.05). It turned out that the creative education program using metaphor has had a positive impact on research participants. Third, in regards to the results of the creative education class satisfaction test, 101 out of 338 students(30%) answered 'Strongly Agree' and 137(41%) answered 'Agree', indicating the subjects' satisfaction with the class was high in general. On the other hand, concerning difficulties of the creative class, 137(41%) answered "Lack of time" as the main factor, followed by 98(30%) "Difficulties of problems they were required to solve", 73(22%) answered "Conflicts with friends", and 24(7%) said "Difficulties of contents." These responses were taken into account as considerations for further development of creative education programs.

  • The sewage and wastewater (SAW) are a well-known major source of eutrophication and greentide in freshwaters and also a potential source of thermal pollution; however, there were few approaches to thermal effluent of SAW in Korea. This study was performed to understand the behavioral dynamics of the thermal effluents and their effects on the water quality of the connected streams during winter season, considering domestic sewage, industrial wastewater and hot spring wastewater from December 2015 to February 2016. Sampling stations were selected the upstream, the outlet of SAW, and the downstream in each connected stream, and the water temperature change was monitored toward the downstream from the discharging point of SAW. The temperature effect and its range of SAW on the stream were dependent not only on the effluent temperature and quantity but also on the local air temperature, water temperature and stream discharge. The SAW effects on the stream water temperature were observed with temperature increase by $2.1{\sim}5.8^{\circ}C$ in the range of 1.0 to 5.5 km downstream. Temperature effect was the greatest in the hot spring wastewater despite of small amount of effluent. The SAW was not only related to temperature but also to the increase of organic matter and nutrients in the connected stream. The industrial wastewater effluent was discharged with high concentration of nitrogen, while the hot spring wastewater was high in both phosphorus and nitrogen. The difference between these cases was due to with and without chemical T-P treatment in the industrial and the hot spring wastewater, respectively. The chlorophyll-a content of the attached algae was high at the outlet of SAW and the downstream reach, mostly in eutrophic level. These ecological results were presumably due to the high water temperature and phosphorus concentration in the stream brought by the thermal effluents of SAW. These results suggest that high temperature of the SAW needs to be emphasized when evaluating its effects on the stream water quality (water temperature, fertility) through a systematized spatial and temporal investigation.

  • Carbamoyl phosphate synthetase 1 deficiency (CPS1D) is an autosomal recessive disorder of the urea cycle that causes hyperammonemia. Two forms of CPS1D are recognized: a lethal neonatal type and a less severe, delayed-onset type. Neonatal CPS1D cases often present their symptoms within the first days of life. Delayed-onset cases are predominantly adolescents or adults, and infantile delayed-onset cases are rare. Severe hyperammonemia in the neonatal period leads to serious brain damage, coma, and death if not treated promptly. Therefore, early diagnosis and acute treatment are crucial. Despite the improvement of treatments, including continuous hemodialysis, ammonia-lowering agents, and a low-protein diet, the overall outcome of severe forms of hyperammonemia often remains disappointing. As the liver is the only organ in which ammonia is converted into urea, liver transplantation has been considered as an elegant and radical alternative therapy to classical dietary and medical therapies. However, liver transplantation has many disadvantages, such as a considerable risk for technical complications and perioperative metabolic derangement, especially in neonates. Additionally, there is a lack of suitable donor organs in most countries. According to recent studies, liver cell transplantation is a therapeutic option and serves as a bridge to liver transplantation. Here, we report a Korean CPS1D patient with novel mutations in CPS1 who was treated by liver cell transplantation after being diagnosed in the neonatal period and showed a good neurodevelopmental outcome at the last follow-up at six months of age.

  • Objective : This study was designed to find the most effective and safest way to overcome Lumbago due to blood stasis and sprain involved in a few Meridian Tendino-musculatures by evaluating the effect of two kinds of Dong-gi(Dong-qi) Acupuncture(DGA) and by reporting their side effects. Material : 97 patients of out and admission patients were selected, who were diagnosed with lumbar sprain caused by repetitive bending, heavy weight lifting, unsuitable posture, concussion and falling down and whose Lumbago due to blood stasis and sprain in the concept of oriental medicine. Methods : 97 patients were divided into three groups. One is exclusive DGA group to which DGA and the method retaining needles on the acupoints for about 20 minutes were applied, the other is DGA combined active exercise group in which patients stretched their Meridian Tendino-muscuIatures with their hips moving up and downward repeatedly during DGA, the third is DGA combined passive exercise group in which patients were made to flex or extend their bodies on the auto flexion-distraction table in a prone position, from 10 to 20 degree, during DGA. In each group, bed rest, physical therapy and herbal medicine were used according to symptoms, in addition to DGA. In DGA method, "Su(Shu)" points of the meridian related to the involved Meridian Tendino-musculature were mainly chosen, that is, Sokkol(Shugu, B65), Hugye(Houxi, SI3), ChungJo(Zhongzhu, TE3) were used, for most LBP belonged to Bladder and Gallbladder Meridian Tendino-musculature disorders. Pyong-Bo-Pyong-Sa(Ping-Bu-Ping-Xie) such as Dong-Gi and Yeom-Jeon(Nian-Zhuan) was applied as Bo-Sa method. For evaluation of effectiveness, new score system was devised by severity of pain and range of movement. the score was given twice at patients' first and last visit and the difference between first and last score was regarded as a evaluation scale, the effectiveness was classified into four grade by evaluation scale.(scale : 12-15; excellent, 8-11; good, 4-7; fair, 0-3; bad) Results : 1. Exclusive DGA, DGA combined active exercise and DGA combined passive exercise group showed 97, 87 and 89% in effectiveness. 2. Exclusive DGA, DGA combined active exercise and DGA combined passive exercise group showed no aggravation of pain, range of movement. 3. In blood test of 34 patients, only one patient showed abnormal rise of sGOT, sGPT and $\gamma$-GTP at his first visit and the others didn't show any detrimental change. DGA had no bad influence upon BUN and creatinine of patients. Conclusion : For complex theraphy combining DGA, exercise, physical therapy and Herbal medicine proved to be highly effective on treating lumbago due to blood stasis and sprain, this is expected to be available for clinical use.

  • To get well matured farm yard manure from ricestraw as quickly as possible during winter season, straw piles wrapped with polyethylene film and/or straw thatch were stored in the vinyl house or open air. Their maturities and changes of temperature in heap were investigated from the beginning of December 1983 to March of next year. Heat increment in vinyl house was high $2-5^{\circ}C$ than at open air at the lowest temperature but it didn't rise over the freezing point. However, the highest temperature was arisen over than $20^{\circ}C$ averagely at the vinylhouse compared to those of open air during three months. Temperature in piles of straw manure was reached to about $70^{\circ}C$ in maximum and rose again very rapidly after repiling in the vinyl house, whereas increment of temperature after repiling was delayed and took long times to reach the maximum temperature at open air. Wrapping with P.E. film also affected the insulation of decomposing heat of straw pile and promoted the repeat of piling even at open air. By these results, ricestraw would be decomposed rapidly by insulation with P.E. film in the vinyl house and could be reached to matured compost for application to field on next spring season. P.E. film covered for vinyl house was endured until May of next year without tear by weathering.

  • The purpose of this study was to evaluate growth changes and skeletal characteristics of Korean children with Class III malocclusions from 10 to 14 years of skeletal age. Radiographs of 60 children with Class III malocclusion and 60 normal controls were assessed. Both groups were subdivided into 6 samples according to sex and skeletal age. Skeletal age was assessed using handwrist X-rays using the Greulich and Pyle norms. The Krogman-Walker plane (occipitale-maxillon) through Sella was used as a reference plane in this study with x-axis perpendicular to the x-axis. Sir Student t-tests were conducted to compare the control group with the Class III group according to each gender a:nd age. The characteristics of Class III malocclusion group compared to the control group included shorter anterior and posterior cranial base, shorter and retrusive maxilla, forger mandible, increased molar-incisor distance, retroclined lower incisors, labially proclined upper incisors, and anteriorly located mandibular molar, smaller upper and middle facial depth, and larger lower facial depth. Landmarks representing facial depth, size of maxilla and mandible, and their AP relationship including anterior facial height indicate that growth characteristic was determined early in life. But growth Pattern of cranial base and some of the dental landmarks showed progressive divergence between Control and Class III groups with age. The position of the posterior border of the mandible was found to be significantly forward in both females and males by the age of 14 and at the anterior border in males and females at all ages. Hyperdivergent mandibular plane, changes in anterior segment of mandible, small anterior cranial base, and decrease in cranial base flexure was also noted.

  • This study was conducted to compare the effect of various LED and UVa light to enhanced coloration of paprika fruits cultivars; 'Special', 'Helsinki'. Immatured paprika fruits were irradiated with red LED, blue LED and UVa lights which were high intensity (red: $50{\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$, blue: $70{\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$, UVa: $3{\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$) and low intensity (red: $20{\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$, blue: $40{\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$, UVa: $0.25{\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$). The coloration of 'Special' cultivar was increased the fastest in high intensity UVa light for 2 days after treatment. There were no significantly difference among treatments except the low intensity UVa light. The coloration of 'Helsinki' was increased the fastest in blue LED light, and followed by red LED light and UVa light for 2 days after treatment. The $a^*/b^*$ value of 'Special' and $b^*$ value of 'Helsinki' that indicated the paprika fruit coloration were generally higher high intensity LED and UVa lights than low intensity LED and UVa lights. We couldn't find out any significantly different coloration effect among all treatments in final days of coloration. and rather than UVa treatment fruit shrunk the surface of paprika fruits.

  • This study was conducted to examine the effects of electrical conductivity (EC) and rootstock on initial growth and physiological response of grafted pepper in protected cultivation. The pepper (Capcicum annuum L.) cultivars 'Nokgwang' was used as scions, and the cultivars used as rootstocks were Capcicum annuum L: 'Kataguruma', 'Conesian hot' and 'Tantan'. The scion cultivar left ungrafted was used as a control. Two experiments were to examine the effects of the EC levels of nutrient solution on the growth and physiological response of grafted pepper, respectively. Nutrient solution was supplied with three level (1.5, 3.0, 5.0dS/m). By the change of nutrient solution EC level, the plant growth of all seedlings decreased with the increase in EC level. grafted seedling was grafted onto rootstock cultivar 'kataguruma' showed higher growth than the other cultivar at the EC 5.0dS/m level. But this result was slightly different by cultivation time (spring and fall). The total N and P concentration were increased with the increase in EC level, but the Ca and Mg concentration were decreased. Photosynthetic rate of ungrafted seedlings decreased at the EC 5.0dS/m level. But there was no difference between EC 1.5 and 3.0dS/m level. Grafted seedlings showed lower photosynthetic rate at the EC 5.0dS/m level. The activity of SOD do not have a uniformly tendency by the EC level. With the EC 5.0dS/m level, the activity of APX attained higher level than the other EC level. Further study will be needed to examine additional cultivation experiment for more variable rootstock, and development of rootstock for salinity tolerance.
