  • In many countries, vaccines are used for the prevention of foot-and-mouth disease (FMD). However, because there is no protection against FMD immediately after vaccination, research and development on antiviral agents is being conducted to induce protection until immunological competence is produced. This study tested whether well-known chemicals used as RNA virus treatment agents had inhibitory effects on FMD viruses (FMDVs) and demonstrated that ribavirin showed antiviral effects against FMDV in vitro/in vivo. In addition, it was observed that combining the administration of the antiviral agents orally and complementary therapy with vaccines synergistically enhanced antiviral activity and preserved the survival rate and body weight in the experimental animals. Antiviral agents mixed with an adjuvant were inoculated intramuscularly along with the vaccines, thereby inhibiting virus replication after injection and verifying that it was possible to induce early protection against viral infection prior to immunity being achieved through the vaccine. Finally, pigs treated with antiviral agents and vaccines showed no clinical signs and had low virus excretion. Based on these results, it is expected that this combined approach could be a therapeutic and preventive treatment for early protection against FMD.

  • Avascular necrosis (AVN) of the humeral head is a rare, yet detrimental complication. Left untreated, humeral head AVN frequently progresses to subchondral fracturing and articular collapse. Cases of late-stage humeral head AVN commonly require invasive procedures including humeral head resurfacing, hemiarthroplasty, and total shoulder arthroplasty (TSA) to improve clinical outcomes. However, in cases of early-stage AVN, core decompression of the humeral head is a viable and efficacious short-term treatment option for patients with pre-collapse AVN of the humeral head to improve clinical outcomes and prevent disease progression. Several techniques have been described, however, a percutaneous, arthroscopic-assisted technique may allow for accurate staging and concomitant treatment of intraarticular pathology during surgery, although further long-term clinical studies are necessary to assess its overall outcomes compared with standard techniques. Biologic adjunctive treatments, including synthetic bone grafting, autologous mesenchymal stem cell/bone marrow grafts, and bone allografts are viable options for reducing the progression of AVN to further collapse in the short term, although long-term follow-up with sufficient study power is lacking in current clinical studies. Further long-term outcome studies are required to determine the longevity of core decompression as a conservative measure for early-stage AVN of the humeral head.

  • An inclusive childcare capacity building program was designed to enhance teacher efficacy and attitudes toward the inclusion of childcare teachers. A total of 36 teachers working in childcare facilities in Gyeonggido participated in this study. Nineteen teachers were assigned to the treatment condition and 17 teachers were assigned to the control condition. The program explicitly addressed 15 topics, including screening and diagnosis, early development, characteristics of disability, family support and related services, IEP, and online site observation. The program was primarily delivered by field professionals using adult learning techniques such as small group activities, reflective journal writings, and online consultation. Teachers in the treatment group outperformed teachers in the control group on three measures of teacher efficacy, teacher play efficacy, and attitudes toward inclusion. The results were statistically significant. The increase in teacher efficacy, play efficacy, and attitudes toward inclusion of teachers was attributed to the well-designed program, encompassing early development, disability characteristics, small group discussions, and online support. The results highlight the importance of providing and disseminating a capacity building program for in-service teachers.

  • Purpose: Follicular lymphoma (FL) is an indolent non-Hodgkin's lymphoma that is highly sensitive to radiotherapy (RT). However, the effectiveness of RT has not been well established. We reviewed our experiences to assess the role of RT for FL and analyze treatment results. Materials and Methods: Retrospective analysis was done on 29 patients who received first RT between January 2003 and August 2013. Of 23 early stage (stage I, II) patients, 16 received RT alone, four received chemotherapy followed by RT, two received RT postoperatively, and one received salvage RT for relapse after resection. Six advanced-stage (stage III, IV) patients received RT after chemotherapy: two received consolidation RT, three received salvage RT for residual lesions, and one received RT for progressive sites. Median RT dose was 30.6 Gy (range, 21.6 to 48.6 Gy). Median follow-up duration was 62 months (range, 6 to 141 months). Results: All patients showed complete response in the radiation field. Eight outfield relapses were reported. Seven patients received salvage treatment (three chemotherapy, four RT). Four patients showed excellent responses, especially to RT. Estimated 5-year and 10-year relapse-free survivals were 72% and 60%. In the RT-alone group, 5-year relapse-free survival was 74.5%. All advanced-stage patients were disease-free with 100% 5-year overall survival. Disease-specific death was noted in only one patient; four others died of other unrelated causes. No significant toxicity was reported. Conclusion: RT resulted in excellent treatment outcomes for all FL stages when used as a primary treatment modality for early stage or salvage-treatment modality for advanced-stage disease.

  • Our previous finding that pre-initiation treatment of indole-3-carbinol (I3C) represents a chemopreventive effect in dimethylbenz[a]anthracene (DMBA)-induced mammary carcinogenesis has prompted us to test the global expression of genes at an early stage. Rats were continuously fed 300 ppm I3C in their diet at 6 weeks of age and were injected with DMBA at 7 weeks of age, and were sacrificed at 8 weeks of age. Global gene expression analysis using oligonucleotide microarrays was conducted to detect altered genes in DMBA- or DMBA plus I3C-treated mammary glands. Altered genes were identified by fold changes of 1.2 and by t-test (P<0.05) from the log ratios of the hybridization intensity of samples between control (Group 1) and DMBA (Group 2), and from those of samples between DMBA (Group 2) and DMBA plus I3C (Group 3). From these genes, we chose altered genes that were up- or down-regulated by DMBA treatment and recovered to the control level by I3C treatment. For early stage of carcinogenesis, I3C treatment induced the recovery to normal levels of several genes including cell cycle pathway (cyclin B2, cell division cycle 2 homolog A), MAP signaling pathway (fibroblast growth factor receptor 1, platelet derived growth factor receptor, beta polypeptide), and insulin signaling (protein phosphatase 1, regulatory (inhibitor) subunit 3B and flotillin 2), which were up-regulated by DMBA treatment. In addition, I3C treatment induced the recovery to normal levels of several genes including those of MAPK signaling (transforming growth factor, beta receptor 1 and protein phosphatase 3, catalytic subunit, beta isoform), which were down-regulated by DMBA treatment. These results suggest that the targeting of these genes presents a possible approach for chemoprevention in DMBA-induced mammary carcinogenesis.

  • This study was carried out to investigate the effects of seeding dates on the yield and feed value of whole-crop barley cultivated in paddy soil. The field experiment was conceived as a randomized block design performed in triplicate with seeding dates of Oct. 19 (T1 as treatment 1), Oct. 26 (T2 as treatment 2), Nov. 2 (T3 as treatment 3), Nov. 9 (T4 as treatment 4), and Nov. 16 (T5 as treatment 5) as treatments. The barley grown in all treatments was harvested on May 21 of the following year. Plant length, fresh yield, dry matter yield, and total digestible nutrient (TDN) yield were higher (p < 0.05) in barley with early seeding dates, whereas crude protein and ether extract were higher (p < 0.05) with late seeding dates. Crude fiber and neutral detergent fiber were highest in the T3 treatment and lowest in the T1 treatment. There was no significant difference between acid detergent fiber and TDN among the different seeding dates. Total mineral contents were higher in the order T1 > T2 > T3 > T4 > T5 (p < 0.05), whereas the total amino acid content increased significantly (p < 0.05) with a delay in seeding date. Free sugar contents (fructose, glucose, and sucrose) were higher with early seeding dates (p < 0.05). Collectively, the results obtained in this study indicate that it is favorable to seed soon after harvesting rice to increase dry matter and TDN yields and mineral and free sugar contents of whole-crop barley in the midlands of Korea.

  • A study was conducted to examine treatment method, proper concentration, and treatment time of gibberellin(GA3) for human labor saving at harvest in 'Campbell Early' grapevine. Fruit berry thinning reduced labor by GA3 40ppm treatment of 5 days prior to full bloom, and, at GA3 10, 20, and 40ppm during full bloom, by 14.27~19.15 minutes/tree. Therefore, although labor was reduced by dipping treatment at 40ppm of 5 days prior to full bloom and 20 and 40 ppm during full bloom, severe shattering was observed at 40ppm dipping treatment, and soluble solids decreased, which suggests difficulty with commercialization. The result suggests that proper time and concentration of GA3 fruit cluster dipping treatment at full bloom and 10 and 20ppm, respectively.

  • Gastric Carcinoma is very plentiful and significant disease in Korean community. The reason is that Gastric Carcinoma is not a simply finding disease with unclear symptoms for early detection. Early detection and early medical treatment of a cancer patient is an important instrument of reducing the mortility rate. The purpose of this study is to identify the effect of audiovisual information with videotape infulencing on knowledge and attitude of early detection of gastric carcinoma. The research design was a non-equivalent control group, pre-post test. The subjects of this study were 52 members of D-taxi drivers which was located in Pusan. The subjects were twenty six experimental group and twenty six control group. The experimental group was collected from January 15, 1999 to January 26, 1999. The control group was collected from the research was 28 minutes video program which was turning out the form of documentary on the based practical experience. And also the experimental tool was used measurung instrument which measured a dependent, variable throughout the consulatation of an percentage, average, standard deviation, ${\chi}^2-test$ and t-test using spss/pc program. The result of this research were as follows : 1)" The experimental group which was offered the video program, should be higher in knowledge of early detection of the gastric carcinoma than the control group" was supported. (t= -7.754, p=.000) 2) "The experimental group which was offered the video program, should be higher in attitude of the early detection of the gastric carcinoma than the control group" was supported.

  • The late Goryeo and Early Joseon period marks the development of Hyang-yak medicine in medical history in Korea. There have been not a few outcomes in organizing Hyang-yak medicine through the hitherto research works, but there has hardly any attempt to view the medicine in the late Goryeo and Early Joseon period from a different standpoint besides Hyang-yak. This writer, in the middle of doing research on 'Book for Alimentotherapy' named "Sikuisikgam", came to know that not a few parts of this book were quoted in a large volume of "Biebaekyobang" in the late Goryeo, "Hyangyakjipseongbang" which compiled the early Joseon Hyangyak medicine, "Uibangyuchi" which wrapped up the medical knowledge in East Asia before the early Ming Dynasty, and "Sikryochangyo" which was a representative book for alimentotherapy in the early period of Joseon Dynasty. The reason that the representative medical books written in the period of Late Goryeo and Early Joseon thought much of the knowledge contained in "Sikuisikgam" is that they showed a great concern for prevention and treatment of diseases through alimentotherapy. When we say that Hyangyak medicine, which has provided the Late Goryeo and Early Joseon medicine, bases its standard on 'Regionality' and 'Properties of Medicinal ingredients', then alimentotherapy puts its focus on a 'Remedial method' itself. As for food, they might have given priority to the food that was easy to get nearby, so there is no way for alimentotherapy but to have the realm which is overlapped with Hyangyak medicine in some measure, That's the very reason why alimentotherapy has remained inseparate from Hyangyak medicine. Through 'Alimentotherapy' and Late Goryeo and Early Joseon medical books, this writer thinks that it might be possible for us to take a view of the Late Goryeo and Early Joseon not only from the perspective of Hyangyak medicine but also from a new perspective of so-called alimentotherapy.

  • In the treatment of functional orthodontic problems, timing is not an issue. All orthodontists start as soon as the condition is recognized. However, there is an active dialogue concerning treatment timing for structure problems. The major points in contention center around the operator's ability is to control the growth of the facial bones and to maintain post-treatment tooth position through the maturation period (especially when this position was gained by techniques involving arch expansion or distal driving of posterior segments). Factors taken into account to determine the best time of orthodontic treatment include diagnosis, interception, growth rate, patient cooperation, eruptive state and treatment period. With those exceptions of all functional problems, mild dental discrepancies and skeletal deficiencies with a predictably excellent growth potential (early treatment), the period immediately following the eruption of the permanent second molars is the period during which most orthodontic treatment should be initiated. At this time the full volume of tooth substances is present, the individual growth pattern in well established, there are sufficient teeth to receive nearly any type of appliances and the patient can easily tolerate the wearing of appliances.
