The study was designed to investigate food waste management practices and to identify factors affecting food waste generation at school food services. A total of 202 dietitians employed at elementary schools participated in the survey. The mean food waste weight per school was 77.54 kg, forty percent of the schools generated food waste of $50{\sim}100kg$ every day and 53% generated plate waste less than 50 kg. Three quarters of the dietitians perceived plate waste as a major component of the food waste and vegetable dishes were a major source of the plate waste. Half of the dietitians used a food waste pick-up service for waste disposal, which was the most preferred waste disposal method. Approximately 90% of the dietitians conducted education on plate waste reduction for students but their perceptions on the effectiveness of the education was inconsistent. The contents were environmental issues (70.3%) and unbalanced food choice (56.7%). According to factor analysis based on performance score, solid waste management practices were grouped into 'information collecting and education', 'supervision of production process', 'cooperation with related groups', and 'control over production planning'. Practices appertaining to 'cooperation with related groups', 'information collecting and education' factor need to be improved. Dietitians should pay attention to 'recycle and reuse of left over' practice. Waste generation differed significantly by dietitians' ages and working experience. In order to reduce plate waste, more effective education materials and methods need to be developed and support from principals, teachers, and parents is necessary.

Background: The aim of study was to confirm the clinical effectiveness and results of wide and single anterior approach for fractures occurring along length of humerus. Methods: A total of 23 patients with humeral fracture were enrolled into our study who were able to participate in at least one year of follow-up. Seven patients had segmental comminuted humeral fractures and 16 patients had distal humeral fractures. We made various tractions of the muscles to expose the proximal and the middle third humerus between the biceps and brachialis and the distal humerus by partial splitting of lateral side of biceps through a single incision. Postoperatively, we measured the Mayo elbow performance index (MEPI). Results: we achieved bone union in all 23 patients. Solid union of the bone was achieved at an average 13.9 weeks. Postoperatively, two complications were observed screw loosening and nonunion. Revision surgery was performed in both patients. The patient with bone nonunion was treated using bone grafts. No postoperative infections or peripheral neuropathies were observed. At the final follow-up (average 20 months), we found that the average MEPI functional score of the patients was 91.7 points regardless of the fracture site. Conclusions: Our whole humerus with a single incision was effective for the treatment of segmental comminuted and distal fractures. we believe it is a useful alternative to preexisting methods of fracture fixation.

Background: This study investigated current research trends in bee venom acupuncture in Korea. Materials and methods: The literature in Korea was reviewed using the search engines Science and Technology Society Village, Korean Studies Information Service System, National Discovery for Science Leaders, and Oriental Medicine Advanced Searching Integrated System. The keywords searched were "bee venom," "apitoxin," "apitherapy," and "bee sting." We selected 412 studies, which included Korean literary studies, experimental studies, and clinical studies. Results: We classified them by publication year, research type, disease and topic, and quality assessment. Among bee venom-related studies, clinical studies (235 studies) outnumbered experimental studies (149 studies) and literary studies (28 studies). Nineteen experimental studies concentrated on the theme of "anticancer." In the type analysis of clinical studies, lumbar disorders comprised 45 of 235 studies, followed by the effect on body. Forty-two randomized controlled trials (RCTs) have been published from 2003 to date (2015). Twenty-two studies used appropriate randomization methods. Fourteen studies had a Jadad score of 4-5 points; 15 studies, 1-3 points; and 13 studies, 0 points. Conclusions: Bee venom treatment is based on Korean traditional medicine theory. Numerous research studies suggest its effectiveness. Effort and academic approach on bee venom are expected to receive a positive evaluation.

This study was conducted to assess the knowledge and educational need of pregnant women relating to antepartum, delivery, puerperium period and to identify the variables which influenced their knowledge and educational need. The study subjects were 77 antepartum women who had antenatal educations and 106 antepartum women who did not have antenatal education. Number of total antepartum women were 183. Data were collected from women who visited for antenatal care at general hospitals and public health centers in Pusan and Kyungnam area using qestionnaires from Feb. 1. 1998 to Apr. 20. 1998. SAS/PC program was used for data analysis. ; Chi-square test, t-test, Pearson's Correlation Coefficient, ANOVA(Duncan procedure) and MANOVA. The results of this study were as follows: 1. Relating to the antepartum period between two groups, the knowledge about the number of antenatal care was low, relating to labor the knowledge about the time fix the fetal position and relating to postpartum, the knowledge about the change of blood pressure and body temperature was low. 2. The comparision means of knowledge were adjusted by social demographic characteristics related to knowledge. There were statistically significant differences in total mean score of knowledge about pregnancy, delivery and postpartum between two groups. In full marks 19, the mean scores of the educational group and non-educational group were 13.08 and 11.74 respectively (P=.000). In resultly, there are statistically significant differences between two groups. The effectiveness of antenatal education group was very high and showed its importance. 3. The comparision means of educational need were adjusted by social demographic characteristics related to educational need. The mean scores of educational need were statistically significantly different in pregnancy, delivery and puerperium period. 4. There were positive correlations between the knowledge and educational level, duration of marriage and total numbers of pregnancy. There were negative correlation between the educational need and age, educational level, duration of marriage and total number of pregnancy. The above results showed the effects of antenatal education.

Objective : Traditionally, staged surgery has been preferred in the treatment of compound comminuted depressed fracture (FCCD) after traumatic brain injury (TBI) and involves the removal of primarily damaged bone and subsequent cranioplasty. The main reason for delayed cranioplasty was to reduce the risk of infection-related complications. Here, the author performed immediate reconstruction using a titanium mesh in consecutive patients with FCCD after TBI, reported the surgical results, and reviewed previous studies. Methods : Nineteen consecutive patients who underwent single-stage reconstruction with titanium mesh for FCCD of the skull from April 2014 to June 2018 were retrospectively analyzed. The demographic and radiological characteristics of the patients with FCCD were investigated. The characteristics associated with surgery and outcome were also evaluated. Results : The frequency of TBI in men (94.7%) was significantly higher than that in women. Most FCCDs (73.7%) occurred during work, the rest were caused by traffic accidents. The mean interval between TBI and surgery was 7.0±3.9 hours. The median Glasgow coma scale score was 15 (range, 8-15) at admission and 15 (range, 10-15) at discharge. FCCD was frequently located in the frontal (57.9%) and parietal (31.6%) bones than in other regions. Of the patients with FCCDs in the frontal bone, 62.5% had paranasal sinus injury. There were five patients with fractures of orbital bone, and they were easily reconstructed using titanium mesh. These patients were cosmetically satisfied. Postoperatively, antibiotics were used for an average of 12.6 days. The mean hospital stay was 17.6±7.5 days (range, 8-33). There was no postoperative seizure or complications, such as infection. Conclusion : Immediate bony fragments replacement and reconstruction with reconstruction titanium mesh for FCCD did not increase infectious sequelae, even though FCCD involved sinus. This suggests that immediate single-stage reconstruction with titanium mesh for FCCD is a suitable surgical option with potential benefits in terms of cost-effectiveness, safety, and cosmetic and psychological outcomes.

This study was to evaluate the effectiveness of the weight control program for female college students. The program was composed of diet and behavioral modifications for 8 weeks. A total of 78 participants enrolled the weight control program. Upon completion of the program, 53 participants experienced weight loss and 25 did not. The intakes of carbohydrate and fat were significantly decreased in both groups. However, the total diet quality index-international (DQII) scores as well as individual scores such as variety scores for protein source and adequacy scores for vegetable, fiber, calcium and vitamin C and moderation scores for empty calorie food were increased significantly in weight loss group only. In the weight loss group, weight, BMI, body fat, percent body fat and waist-hip ratio were decreased significantly. In addition, compared to the weight gain group, the weight loss group had higher changes in weight (weight loss group: -2.6% vs weight gain group: 1.5%, p < 0.001), body fat (-6.0% vs 0.0%, p < 0.001), percent body fat (-3.1% vs -0.3%, p < 0.001), waist-hip ratio (-1.0% vs 0.5%, p < 0.001) and BMI (-2.6% vs 1.3%, p < 0.01). There was no difference in blood profiles between the two groups. The changes in DQI-I scores were significantly correlated with the changes in body weight (r = -0.239, p < 0.05) and BMI (r = -0.224, p < 0.05), indicating that effective nutrition education could help improve diet quality leading to successful weight management among female college students.

Objective: The aim of our study is to evaluate the effectiveness of unilateral hemilaminectomy for bilateral decompression in elderly patients with degenerative spinal stenosis. For this purpose, we studied the co-morbid condition and clinical outcome of patients who underwent decompressive surgery using the unilateral approach technique. Methods: Thirty-four patients over 65years of age who underwent unilateral partial laminectomy for bilateral decompression from January 2000 to October 2003 were analyzed. These patients were studied for preoperative co-morbid condition and physical status according to the American Society of Anesthesiologists(ASA) classification, postoperative morphometrical change, and clinical outcomes, including visual analogue scale(VAS) score. The mean follow-up was 23months (range 6 - 48months). Results: A patient's physical status was recorded as class I, II, or III by ASA classification, which correlated to 41.2%, 44.1%, and 14.7% of patients, respectively. The cross-sectional area of the pre- and postoperative dural sac at the level of the stenosis was $52.5{\pm}19.9mm^2$ and $110.6{\pm}18.2mm^2$, respectively. The outcome was excellent in 8.8%, good in 58.8%, fair in 23.6%, and poor in 8.8% of the patients. The VAS was changed postoperatively to $3.1{\pm}1.2$. There was no operation-related transfusion yet there was no evidence of postoperative instability at the follow-up examination. Conclusion: Unilateral laminectomy for bilateral decompression, in spite of the limited exposure, can result in satisfactory decompression of the lumbar spinal stenosis and tolerable clinical outcome. This approach is thought to be appropriate for elderly patients who have a greater surgical burden.

Objective : Craniovertebral junction (CVJ) consists of the occipital bone that surrounds the foramen magnum, the atlas and the axis vertebrae. The mortality and morbidity is high for irreducible CVJ lesion with cervico-medullary compression. In a clinical retrospective study, the authors reviewed clinical and radiographic results of occipitocervical fusion using a various methods in 32 patients with CVJ instability. Methods : Thirty-two CVJ lesions (18 male and 14 female) were treated in our department for 12 years. Instability resulted from trauma (14 cases), rheumatoid arthritis (8 cases), assimilation of atlas (4 cases), tumor (2 cases), basilar invagination (2 cases) and miscellaneous (2 cases). Thirty-two patients were internally fixed with 7 anterior and posterior decompression with occipitocervical fusion, 15 posterior decompression and occipitocervical fusion with wire-rod, 5 C1-2 transarticular screw fixation, and 5 C1 lateral mass-C2 transpedicular screw. Outcome (mean follow-up period, 38 months) was based on clinical and radiographic review. The clinical outcome was assessed by Japanese Orthopedic Association (JOA) score. Results : Nine neurologically intact patients remained same after surgery. Among 23 patients with cervical myelopathy, clinical improvement was noted in 18 cases (78.3%). One patient died 2 months after the surgery because of pneumonia and sepsis. Fusion was achieved in 27 patients (93%) at last follow-up. No patient developed evidence of new, recurrent, or progressive instability. Conclusion : The authors conclude that early occipitocervical fusion to be recommended in case of reducible CVJ lesion and the appropriate decompression and occipitocervical fusion are recommended in case of irreducible craniovertebral junction lesion.
