Purpose: To evaluate the drainage effect of silk suture material following aspiration of the bursa as an early treatment of chronic prepatellar bursitis. Materials and Methods: Twelve cases, which have over two weeks of history and over one year of follow-up, were investigated. The average duration of follow-up was 18.3 months. The average symptom duration before introduction into this study was 2.2 months. With an aseptic technique, the aspiration of the bursa was done with spinal needle or injection needle and syringe and then the insertion of silk suture material through the aspiration needle was performed. Over one year follow-up, recurrence, infection, pain, and limitation of range of motion were investigated by telephone interview. Results: Redness around the insertion site of silk suture material was found in all cases, but there was no development of active infection in eleven cases. At five days after procedure, a supprative infection was developed in one case. The results were considered satisfactory in 92% of cases and the average duration of treatment is 14.5 days. Conclusion: The drainage with silk suture material following aspiration of the bursa is effective and less invasive method in the early treatment of chronic prepatellar bursitis.

The purpose of this study was to find out the relationships between emotional labour and depressive symptoms among nurses in university hospitals. Subjects were 514 nurses working at three university hospitals in Daejeon City, and the survey was a structured self- administered questionnaire based from April 1 until May 31 2012. As a results, the level of depressive symptoms by the subjects emotional labour level was significantly higher in the group with higher total average points of the emotional labour than the lower group, As for the correlation between the level of depressive symptoms and emotional labour factors, the depressive symptoms points showed significant positive correlation with the total points of the emotional labour. As a result of hierarchical multiple regression, age, leisure time, coffee consumption, subjective health status, physical burden of work, sense of satisfaction at work, fit to the job and emotional labour were selected as significant variables and related variables effecting the level of depressive symptoms. These variables' descriptive power was 39.4%, especially, it can be seen that 11.0% descriptive power increased by putting the emotional labor variables. The results above imply that there is significant relation between emotional labor and depressive symptoms and various variables such as socio-demographic characteristics, health-related behavior factors and job-related factors. Also, it can be seen that the emotional labour and depressive symptoms showed significant positive correlation. Therefore, the development and implementation of a program to control emotional labor appropriately should be required for lowering the level of depressive symptoms.

Temporomandibular joint ankylosis is the movemental obstacle of mandible which depend on proliferation of bony or fibrous tissue in temporomandibular joint structure by various causes. In order to treat this, various surgical methods have been performed, but no operative methods have been produced consistently successful results. This research has been performed to the patients who had been operated due to temporomandibular joint ankylosis by studying classification, cause, onset, duration, anesthesia and treatment method, symptom, change of mouth opening, complication through medical record, X-ray, follow-up for being a help to proper selection of treatment method and evaluation of prognosis. The author obtained the following results by analyzing 44 cases among patients who had been operated due to temporomandibular joint ankylosis during 8 year hospitalization from 1986 to 1993 in Dept. of Oral & Maxillofacial Surgery of Seoul National University Hospital. 1. The occurrence was in the order of below 10, 20's, 10's, 30's. The average of occurrence was 12.95. Illness period was 50.0% within 10 years and 50% beyond 10 years. The average period of illness was 13.33 years. 2. Trauma occupied 54.5% of causes and inflammation occupied 45.5%. Men had more occurrences due to trauma and there was no difference in case of inflammation. 3. In nasotracheal intubations for general anesthesia, the cases of using fiberoptic laryngoscope occupied 40.9%, direct or blind nasotracheal intubation occupied 40.9% and the cases of using tracheostomy occupied 18.2%. 4. In operative approaching methods, submandibular & preauricular approach were mainly applied, and in operative methods, high condylectomy(Group I) occupied 11.4%, arthroplasty without interpositional material following condylectomy or gap ostectomy(Group II) occupied 11.4%, with interpositional material following high condylectomy (Group III) occupied 40.9%, and using condylar reconstruction following condylectomy or gap ostectomy(Group IV) occupied 36.6%. 5. In change of mouth opening reformed after surgery, Group III showed the best result of average 23.5mm, Group IV showed 16.3mm, Group I showed 14.9mm and Group II showed 10.2mm of reformation. Summarizing the results as written above, it is considered that early treatment is important as soon as possible in Temporomandibular joint ankylosis. It is recommended in surgical method what can lead to postoperative early movement maintaining anatomaical & functional form, and then the development of various surgical methods will be requested.

Objectives: To identify the factors affecting long-term adherence to methylphenidate treatment in children with attention-deficit hyperactivity disorder (ADHD). Methods: A retrospective medical record review of 239 ADHD patients (mean age $9.3{\pm}2.6$ years, range 6.0-17.4 years) who had visited the child and adolescent psychiatry clinic at a university hospital, in Seoul, Korea from March 2005 to February 2008. Subjects were diagnosed as ADHD based on the criteria set forth in the Diagnostic and Statistical Manual of Mental Disorders 4th edition, text revision version (DSM-IV-TR) and underwent neuropsychological tests including the continuous performance test (CPT). Treatment discontinuation was defined as the last prescription date when the medication possession rate (MPR) became less than 0.80. Subjects were divided into three groups and labeled as Group I, non-adherence without pharmacotherapy, Group II, non-adherence with short-term pharmacotherapy, and Group III, adherence with long-term pharmacotherapy. Results: Ninety (37.7%) patients were grouped as non-adherent (Groups I+II) and 149 (62.3%) as adherent (Group III). The adherence group exhibited lower intelligence, higher symptom severity, and a higher number of comorbid psychiatric disorders than controls. The use of stimulants was significantly associated with long-term adherence to treatment. Additionally, the duration of interval between the date of the first visit and the date of the first prescription was positively associated with long-term adherence. Conclusion: About two-thirds of patients diagnosed as ADHD adhered to the treatment six months after the first visit. With respect to patient evaluation and the development of treatment strategies, factors affecting early drop-out and longer follow-up must be considered.

The purpose of this study is to find the effect of group counseling program based on reality therapy that is developed by researcher and to investigate whether the program can decrease the academic stress of elementary school students. For this study, firstly a framework for academic stress decrease programs is established and a program is developed in accordance with the framework. Secondly, in order to verify the effect of the program, both quantitative and qualitative methods were applied to 6th grade students through a academic stress test. Experimental group and control group is composed of 18 students, each. During a two month-experimental period, group counseling program based on reality therapy was implemented to the experimental group for 10 sessions but not to the control group. The program included nicknaming, recreation activities to promote friendliness among participants and other various activities to decrease the academic stress. The results of the quantitative and statistical research are as follows: First, group counseling program based on reality therapy is effective to decrease of elementary school students' academic stress. Second, sub factor(such as perceptions of academic stress cause, symptoms of academic stress)of academic stress is significantly decreased in experimental group. But no significant difference is found in control group. Third, for some sub factor(career, friend-relationship, house-environment, behavior-symptom), an independent-sample test and a paired-sample test showed different results: the paired-sample test showed no significant differences in experimental group while the independent-sample test showed significant decrease of academic stress. The results of the qualitative research based on student commentaries on the program is as follows: First, experimental group students report that the program based on reality therapy was effective to decrease of academic stress. Second, experimental group students' commentaries shows that students could remember the WDEP, 'act' factor and acquire the solution of academic stress. Third, for a group counseling, students reported the interest about positive feedback, searching on themselves, growth of human-relationship. This means that the program developed on this study is suitable for group counseling program. In conclusion, this study proves that group counseling program based on reality therapy is effective to decrease of elementary school students' academic stress by increasing individual internal-control. Therefore, it is necessary that we should develop and apply similar program to elementary school students in other to decrease students' academic stress. school students in other to decrease students' academic stress.

Post-harvest trunk injection of oxytetracycline-HCl(OTC) was attempted for the control of jujube witches'-broom. Diseased jujube(Zizyphus jujuba) trees with 9 to 16cm trunk diameters were treated with OTC ranged from 2g to 6g according to the size of trunk diameter. OTC dissolved in 0.51 or 1.01 of water was transfused into diseased trees by gravity flow injection during September and October. All these OTC concentrations prevented symptom development for two growing seasons and restored previously severely diseased trees to normal conditions. There was no differences in control effect between 0.51 and 1.01 OTC solutions. With these high OTC concentrations, no phytotoxicity was observed in the new leaves of the following year. Mycoplasma -like organism (MLO)-specific fluorescence was absent in the phloem of recovered tissue when examined by fluorescence microscopy using DAPI(4'-6-diamidino-2-phenylindole.2HCl) staining, indicating the disappearance of MLO by the action of OTC.

Objectives The purpose of this review is to analyse the trend in papers related with Korean Medicine Treatment after musculoskeletal disorder surgery. Methods We reviewed Korean Medicine papers by searching Korean web databases 'Korea Traditional Knowledge Portal', 'Scientific and Technological Information Integration Service (NDSL)', 'Academic Research Information Service (RISS)', 'Korea Medical Informati on Portal (OASIS)'. We classified the papers by the year of publishment, the title of journals, the type of study, surgery region, chief complain after surgery, main treatment, periods after surgery, assessment for outcomes. Results 1. Korean Medicine treatment after musculoskeletal disorder surgery has received more attention than in the past and there are attempts to do various studies besides the case reports. 2. 41 research papers were divided in to 3 original articles, 3 review articles, 35 case reports. But almost presented a low level of evidence. 3. Pain was the most common symptom after the musculoskeletal disorder surgery. Pain should be the primary goal of Korean rehabilitation treatment after musculoskeletal disorder surgery. 4. Assessment tools for outcome were concentrated in questionnaries, VAS and NRS. In order to evaluate better, it is necessary to evaluate the overall condition of the patient such as the quality of life evaluation and patient satisfaction. Conclusions In this study, we expect that the development and clinical application of Korean rehabilitation treatment program after musculoskeletal disorder surgery will be actively pursued.

A wilt disease on lettuce was observed in 2006 and 2007 in commercial plastic house at main production areas of lettuce in Icheon, Yongin and Goyang of Gyeonggi Province. The disease was characterized by the wilting of lower leaves, accompanied by stunting symptoms of the whole plants. Old affected stems showed the black streak in the vascular system. The pathogen, Fusarium oxysporum f. sp. lactucae was isolated from stems and roots of diseased plants. Isolated pathogen also produced the microconidia and macroconidia with chlamydospores on carnation leaf agar medium. The pathogen easily invaded and made many chlamydospores on the roots of lettuce and also made dark streaking through the vascular in the lettuce stems. The density of Fusarium sp. in the severely diseased field soil was more higher populations than that in the healthy and less diseased field soil. The minimum population of pathogen would be above $10^3$cfu/g soil to induce the Fusarium wilt on lettuce in plastic house. The results of pathogenicity test showed 'Sunpung' and 'Mipungpochap' was high susceptible to Fusarium pathogen isolates while some cultivar 'Mihongjeokchukmyeon' and 'Jinjachukmyeon' showed moderate resistance. Disease development for some lettuce was related to treated temperature, so the symptom was more severe above $25^{\circ}C$. Selection of appropriate lettuce cultivar and planting time should be related for the successful control of Fusarium wilt.

Lysin motif (LysM) proteins are reported to be necessary for the virulence and immune response suppression in many herbaceous plant pathogens, while far less is documented in woody plant pathogens. In this study, we preliminarily characterized the molecular function of a LysM protein LtLysM1 in woody plant pathogen Lasiodiplodia theobromae. Transcriptional profiles revealed that LtLysM1 is highly expressed at infectious stages, especially at 36 and 48 hours post inoculation. Amino acid sequence analyses revealed that LtLysM1 was a putative glycoprotein with 10 predicted N-glycosylation sites and one LysM domain. Pathogenicity tests showed that overexpressed transformants of LtLysM1 displayed increased virulence on grapevine shoots in comparison with that of wild type CSS-01s, and RNAi transformants of LtLysM1 exhibited significantly decreased lesion length when compared with that of wild type CSS-01s. Moreover, LtLysM1 was confirmed to be a secreted protein by a yeast signal peptide trap assay. Transient expression in Nicotiana benthamiana together with protein immunoblotting confirmed that LtLysM1 was an N-glycosylated protein. In contrast to previously reported LysM protein Slp1 and OsCEBiP, LtLysM1 molecule did not interact with itself based on yeast two hybrid and co-immunoprecipitation assays. These results indicate that LtLysM1 is a secreted protein and functions as a critical virulence factor during the disease symptom development in woody plants.

Efficacy of different control methods was evaluated for disease management of tomato bacterial wilt caused by $Ralstonia$ $solanacearum$. All six chemical pesticides applied to the bacterial suspension showed $in$ $vitro$ bactericidal activities against $R.$ $solanacearum$. Minimal inhibitory concentrations (MICs) of copper hydroxide (CH), copper hydroxide-oxadixyl mixture (CH+O), and copper oxychloride-dithianon mixture (CO+D) were all 200 ${\mu}g/ml$; MIC of copper oxychloride-kasugamycin (CO+K) mixture was 100 ${\mu}g/ml$; MICs of both streptomycin- validamycin (S+V) and oxine copper-polyoxine B mixture (OC+PB) were 10 ${\mu}g/ml$. Among these chemical pesticides, treatment of the detached tomato leaves with the 5 pesticides (1 mg/ml), except for OC+PB delayed early wilting symptom development caused by the bacterial inoculation ($10^6$ and $10^7$ cfu/ml). Four pesticides, CH, CH+O, CO+K and S+V, showed disease protection in pot analyses. Six plant essential oils, such as cinnamon oil, citral, clove oil, eugenol, geraniol and limonene, differentially showed their antibacterial activities $in$ $vitro$ against $R.$ $solanacearum$ demonstrated by paper disc assay. Among those, cinnamon oil and clove oil exert the most effective activity for protection from the wilt disease caused by the bacterial infection ($10^6$ cfu/ml). Treatment with cinnamon oil and clove oil also suppressed bacterial disease by a higher inoculum concentration ($10^7$ cfu/ml). Clove oil could be used for prevention of bacterial wilt disease of tomato plants without any phytotoxicity. Thus, we suggest that copper compounds, antibiotics and essential oils have potency as a controlling agent of tomato bacterial wilt.
