Objectives: This study aimed to investigate the current status of nutrition education via a free learning semester program (NE). The understanding of the program, the potential difficulties, and future initiatives for NE improvement were also investigated. Methods: A total number of 161 nutrition teachers from Gwangju and Jeonnam filled in a questionnaire and participated in this survey, which was performed from July to August 2019. Results: Our results showed that 8.1% of the nutrition teachers had taught nutrition education in free learning semester programs. The most frequently implemented model was subject selection, followed by club activities. Most of the nutrition teachers comprehended the purpose of NE. The attitude of nutrition teachers to NE differed by the understanding of its purpose. Positive attitude was evident due to a better understanding of the purpose by nutrition teachers. Nutrition teachers reported the most common difficulties of NE were the lack of preparation due to the heavy workload and the lack of a standard running program.The most effective method of NE was the activity classes. The experience of practicing NE influenced the choice of contents for each operating model. Nutrition teachers that were experienced in NE conducted via free learning semester programs preferred the selected topics model, but those without experience chose the career search model. Conclusions Although some obstacles exist, nutrition teachers had a positive attitude and perceived well the importance of NE. Therefore, the awareness for the significance of NE of nutrition teachers needs to be improved. For better NE practice, it is necessary to reduce/ manage the workload of general food service. Furthermore, the development of standard running and promotion programs, and teacher training programs should be ensured.

BACKGROUND: Osteoporosis is an important and common medical problem in postmenopausal women. Depression is another major public health concern. Due to the high prevalence of both depression and osteoporosis, even a weak association between them might result in a greater health problem. We have investigated whether depression is associated with bone mineral density (BMD) in peri- and postmenopausal women. METHODS: The study subjects who visited the office of family medicine department and the health screening and diagnosis center in one general hospital from January to May, 2000 were selected. BMD was measured at the lumbar spine using Dual Energy X-ray Absorptiometry. We evaluated the depression scale using the Beck Depression Inventory. The subjects who had disorders known to interfere with bone metabolism or those who had taken medication related to depression were excluded from the study. RESULTS: Significant positive correlation were noted between BMD and height and weight (P<0.05) but no correlation was found with depression in perimenopausal women. In postmenopausal women, significant negative correlation was noted between BMD and age, and postmenopausal duration and depression. Significant positive correlation was found between BMD and height and weight (P<0.05). CONCLUSION: Our results showed that depression was associated with BMD in postmenopausal women which was independent of other factors strongly associated with osteoporosis.

OBJECTIVE: The purpose of this study is to evaluate the role of cold knife conization in the diagnosis and management of cervical neoplasia. METHODS: Cold knife conization was performed in total 163 patients from January 1992 to December 2003. The results of PAP smear and colposcopy-directed biopsy were compared with the pathologic diagnosis of conization. And we evaluated the rate of positive margin and the presence of residual lesion. And then, we reviewed the pregnancy outcome after conization. RESULTS: The rate of agreement between PAP cytology and conization was 45.4%, and the rate of agreement between colposcopy-directed biopsy and conization was 65.6%. Hysterectomy was done in 102 patients (62.6%). The positive rate of resection margin was 19.6%. The incidence of residual lesion after conization was 31.2% in margin (+) and 1.4% in margin (-). We evaluated 7 cases of pregnancy after conization. CONCLUSION: Cervical conization as surgical treatment was effective in cervical neoplasia patients, especially young patients, with continuous follow-up.

(188)Re(Rhenium) is easily obtained from an in-house (188)W/(188)Re generator that is similar to the current (99)Mo/(99m)Tc generator, making it very convenient for clinical use. This characteristic makes this radionuclide a promising candidate as a therapeutic agent. Polyethylenimine (PEI) is a cationic polymer and has been used as a gene delivery vector. Positively charged materials interact with cellular blood components, vascular endothelium, and plasma proteins. In this study, the authors investigated whether intratumoral injection of (188)Re labeled transferrin (Tf)-PEI conjugates exert the effect of radionuclide therapy against the tumor cells. When the diameters of the Ramos lymphoma (human Burkitt's lymphoma) xenografted tumors reached approximately 1 cm, 3 kinds of (188)Re bound compounds (HYNIC-PEI-Tf, HYNIC-PEI, (188)Re perrhenate) were injected directly into the tumors. There were increases in the retention of (188)Re inside the tumor when PEI was incorporated with (188)Re compared to the use of free 188Re. The (188)Re HYNIC-Tf-PEI showed the most retention inside the tumor (retention rate=approximately 97%). H&E stain of isolated tumor tissues showed that (188)Re labeled HYNIC-PEI-Tf caused extensive tumor necrosis. These results support (188)Re HYNIC-PEI-Tf as being a useful radiopharmaceutical agent to treat tumors when delievered by intratumoral injection.

BACKGROUND: Rescently, the immunotherapy against infectious disease and cancer is being actively studied, and high yield of pure CD14+ monocytes is a key of concern. In this study, we optimized the percoll gradient method to increase the purity and yield of monocytes from peripheral mononuclear cells. METHODS: We separated mononuclear cells (MNC) from healthy donors, and monocytes from MNC were separated with the various density of percoll gradient. After centrifugation, we determined the most efficient density of the percoll gradient to get the highest yield and purity of monocytes. We also obtained monocytes by the plastic absorption method. Monocytes were differentiated into dendritic cells (DC) and the efficacy of differentiation to DC is confirmed and compared by morphological characteristics and using a flowcytometer. RESULTS: The purity of monocytes was 51.3+/-8.3% by the 35% percoll gradient method and the purity was improved to 82.9+/-4.2% with 100% of yield by repeating the same method. Therefore, the yield of mature dendritic cells was 3.6+/-0.9% of the total input MNC by the 35% percoll repetition method, which was 1.7 times higher than the plastic adherent method (2.1+/-0.5%). CONCLUSION: This study shows a cost-effective method to isolate CD14+ monocytes and these cells demonstrate high differentiation rate to DC. This process will be valuable for obtaining a sufficient number of DC.

PURPOSE: This study was performed to investigate the present condition of drug abuse and its association with depression, self-rated health and health behaviors by job status in Korean adults. METHODS: Data were derived from the study on four addiction problem and suicide in 2014. Multiple logistic regression was used to analyze patterns of drug abuse according to depression, self-rated health and health behaviors. RESULTS: The prevalence of drug abuse during the past year was 17.1% of the 4,018 subjects. About 3.3 times risk for drug abuse was found among individuals who had high depression scores. The risk of drug abuse was higher among those who were smoking (OR:1.46, 95% CI:1.17~1.83), drinking more frequently (OR:1.30, 95% CI:1.07~1.58), sleeping insufficiently (OR:1.31, 95% CI:1.03~1.67), eating irregularly (OR:1.45, 95% CI:1.19~1.76). Drug abuse problem was detected more seriously among employed than unemployed adults. CONCLUSION: Health-related behaviors, such as smoking, drinking, sleeping, eating should be considered simultaneously when designing strategies to deal with drug abuse problem, and it is important to understand the interaction between drug abuse and mental health. Furthermore, workplace based intervention can be effective in solving drug abuse problem.

Cardiac manifestations of hypereosinophilic syndrome rarely include left ventricular thrombosis leading to peripheral emboli. And the cases of thrombectomy in patients with left ventricular thrombus and hypereosinophilic syndrome are extremely rare. Recently we experienced a 58-years-old woman with hypereosinophilic syndrome, the history of thalamic infarction and a huge thrombi in left ventricle. We report this case with literatures.

In order to investigate the molecular basis of the aging process in brain, we have employed high-density oligonucleotide microarrays providing data on 10,108 gene clusters to define transcriptional patterns in three brain regions, cerebral cortex, cerebellum, and hippocampus. Comparison of the expression patterns between young (6-week-old) and aged (17-month-old) C57BL/6 male micerevealed that about ten percent (1098) of the genes showed a significant change in the expression level in at least one of the three tissues. Among them, 23 genes were upregulated and 62 genes were downregulated in all three tissues of the old mice. The number of genes upregulated exclusively in hippocampus (337) was much larger compared to other tissues. Gene ontology-based analysis showed the genes related with signal transduction or molecular transports are more likely to be upregulated than downregulated in the aging process of hippocampus. These data may provide some useful means for elucidating the molecular aspect of aging in hippocampus and other regions in brain.

BACKGROUND/OBJECTIVES: This research was conducted to compare lecture-and experience-based methods of nutritional education as well as provide fundamental data for developing an effective nutritional education program in elementary schools. SUBJECTS/METHODS: A total of 110 students in three elementary schools in Jeollanam-do were recruited and randomly distributed in lecture-and experience-based groups. The effects of education on students' dietary knowledge, dietary behaviors, and dietary habits were analyzed using a pre/post-test. RESULTS: Lecture-and experience-based methods did not significantly alter total scores for dietary knowledge in any group, although lecture-based method led to improvement for some detailed questions. In the experience-based group, subjects showed significant alteration of dietary behaviors, whereas lecture-based method showed alteration of dietary habits. CONCLUSIONS: These outcomes suggest that lecture-and experience-based methods led to differential improvement of students' dietary habits, behaviors, and knowledge. To obtain better nutritional education results, both lectures and experiential activities need to be considered.

Adenomyomas of the stomach are rare tumors characterised by duct/gland-like structures embedded within a smooth muscle stroma. A 5-year-old female patient was admitted to the department of Pediatrics, Ewha Womans University MokDong Hospital with the history of severe epigastric pain and vomiting for 1 day. Esophagogastroduodenoscopy showed bridging fold with central dimpling on posterior wall of prepyloric antrum. Endoscopic biopsy was nondiagnostic. The patient complained epigastric pain continuously and underwent wedge resection. Pathologic examination showed an adenomyoma of the prepyloric antrum. After wedge resection, the patient did not complain epigastric pain during the postoperative follow-up. We report an unusual case of an adenomyoma of stomach.
