  • The PCL reconstruction in chronic isolate PCL reconstruction was still controversy. 1) In isolate PCL deficient knee, functionally not so bad as like ACL deficient knee. 2) The result of the PCL reconstruction was not as good as ACL reconstruction. Therefore, isolate PCL injuries has been treated as nonoperatively. Hey Grovere, who was the first to attempt an intra-articular reconstruction of the PCL, utilized the semi-tendinous tendon other static procedures have been described in only a few cases with very limited follow-up. Dynamic procedures utilizing the medial head of the gastrocnemius has been reported by Hugston and Degenhardt, Kennedy and Grainger, and Insall and Hood. These procedures did not improve static stability. Dr Clancy, who was introduce the use of BPTB for the PCL reconstruction transtibial and femoral tunnel. From 1995, untill early 1990 PCL reconstruction was done as tend as placement of the isometric point. Physiometic placement of Anatomical placement of the femoral tunnel in PCL reconstruction were introduced in 1995. Tibial Inlay Technique was reported by Dr Berg in 1995. The main advantage of the tibial Inlay Technique was to avoid fraying of the graft at the posterior tibial tunnel orifice. In complete PCL ruptured and severely posterior unstable knee, dual femoral tunnel technique will be to get better result than one bundle technique. To achieve restoration of normal posterior laxity, it is critical to address the posterior as well as the posterolateral structures. Futher research is necessary to evaluate new surgical approches such as double-bundle reconstructions and tibial inlay techniques as well as improved techniques for capsular and collateral ligament injuries.

  • Purpose: The purpose of this study is to investigate cardiovascular risk factors, their interaction, degree of cardiovascular risk and to analyze the effects of related fcators in women workers. Method: A Survey was conducted in 529 employed women in 36 workplaces from October 25, 2002 to December 12, 2002. The survey was distributed and collected by occupational health nurses working at work sites. Result: The result were as followings; The female workers had about 2 cardiovascular risk factors. 82.1% were not exercising more than 3 times a week, 45.9% reported noise-exposure, 38.2% had higher perceived stress, 25.4% were shift-workers, 10.4% were long-time workers(over 60hour/week), 4.4% were frequent drinker, 3.9% were current smokers. The rate of obesity in measured as BMI greater than 25 was 4.0%. Many cardiovascular risk factors were correlated. Job-related and health behavior-related cardiovascular risk factors were correlated statistically. Expose to noise, reported perceived stress were powerful predictors in their degree of cardiovascular risk. Conclusion; Based on the results of this study, cardiovascular prevention programs for women in workplace should be designed as a multifactorial approach, which include stress management and job-related risk factor management as essential components to be effective in addressing the needs of the population.

  • The morphology and whole genome sequence of Spodoptera exigua nucleopolyhedrovirus K1 (SeNPV-K1) isolated in Korea were analyzed for the use as an eco-friendly control source against S. exigua. The polyhedra of SeNPV-K1 was amorphous with a size of 0.6-1.8 ㎛, and there was no external difference with the previously reported SeNPV. As a result of analyzing the nucleotide sequence of the whole genome, it was composed of 135,756 bp, which is 145 bp more than that of the previously reported SeNPV. The G+CG+C content was 44% and there were 6 homologous repeated sequences, so there was no significant difference from the previous report. As a result of ORF analysis, SeNPV-K1 had 137, two fewer than those previously reported, and 4 ORFs present only in SeNPV-K1 were confirmed. These 4 ORFs are non-essential genes and were not considered to have a significant influence on the characteristics of the SeNPV. The genome vista analysis showed that the overall sequence similarity between SeNPV-K1 and the previously reported SeNPV was very high. The whole genome of SeNPV-K1 analyzed for the first time in Korea was found to be similar to the previously reported SeNPV, but it was confirmed that it was a novel resource in Korea with different isolate.

  • Purpose: The study aimed at monitoring the immune status of health care workers (HCWs) of a tertiary hospital after accidental exposure to Hepatitis B virus (HBV). Methods: Between January 2004 and December 2006, 353 cases of exposure to Hepatitis B virus were reported. The HBV-exposed HCWs were required to undergo follow-up serum tests to analyze their immune status one year after the exposure. The obtained data were then analyzed to determine the incidence of exposure and of sero-conversion. Results: In this hospital, an average of 9.8 cases of Hepatitis B exposure among HCWs was reported in a month. Follow-up tests conducted after exposure revealed that 90.4% of the HBV-exposed HCWs were positive for Hepatitis B antibody and 66.9% of the HBV-exposed HCWs were reported to have antibody levels exceeding 10 mIU/mL. Results of serum tests for the HBV antigen conducted one year after exposure were negative for all the exposed HCWs. Conclusion: Among the 79.6% of the HCWs who underwent serum tests one year after exposure the HBV sero-conversion rate was 0.0%. However, a further investigation in the form of long-term and multi-center studies is required to confirm this result. Furthermore, an active system should be established to ensure that all exposed HCWs undergo follow-up serum tests.

  • A high prevalence of farmer's work-related musculoskeletal disorders(MSDs) have been reported in precedent studies. To offer the basic data for reducing the melon farmer's MSDs, a questionnaire survey about MSDs symptoms and work loaded body part and video analysis by 3 checklist(REBA, RULA, OWAS) for musculoskeletal risk assessment were carried. 94 melon farmers for this questionnaire and 1 typical farm for risk assessment were participated. A total of 80.9% of the farmers reported musculoskeletal symptoms and 60.6% reported musculoskeletal symptoms over NIOSH standard. The mainly symptom body part is low back, knee and shoulders. Main risk factors in melon farm are awkward postures, heavey/frequent lifting and repetitive hand/arm motions. The high risk tasks induced by video analysis were harvesting, removing the sprouts and covering with rags. These result can be used practically for planning intervention strategy and programs to prevent farmer's MSDs.

  • The aim of this study was to investigate the problem areas in the current clinical training of biomedical laboratory science education which may guide the development of an effective strategy for managing clinical training for biomedical laboratory science students. A self-reporting questionnaire was developed by the researchers. This survey was conducted between May 1st and May 15st in 2009 and 92 questionnaires were collected from senior biomedical laboratory science students. In Analyzing data, chi-square test was used for categorical variables. 82.6% of respondents was satisfied with conditions of the training institutes. 30~40% of the respondents reported that they were not satisfied with the programs and supervision systems for training students even though the staff members of other disciplines were supportive in general. Although 83.7% of the respondents reported that they were obtaining information and knowledge for their professional carrier through the training, 70.7% of the respondents reported that they had negative experiences during the training. According to the result of the survey, it can be inferred that the structure of the training education needs to be more systematically organized in order to train the well prepared entry-level biomedical laboratory scientists.

  • Endometriosis involving sites outside the pelvic cavity is a relatively uncommon occurrence and its frequency is cited as being less than one percent of all occurences of endometriosis. Sites previously reported in literature have described involvement of the extraperitoneal portion of the round ligament, the rectosigmoid, the appendix, and the ileum. Other more distal sites reported to have been found to have endometriosis lesions include the inguinal ligaments, the umbilicus, abdominal incisional wounds, thoracic lesions involving the pleura or diaphragm which may result in catamenial pneumothorax, the kidneys, and vulvar episiotomy wounds. Endometriosis have even been reported to occur in males. In this presentation, three cases of endometriosis, two involving the vulvar area and one involving a Pfannenstiel incision wound, is presented with a review of the pertinent literature in order to discuss its etiology, pathology, diagnosis and treatment.

  • Purpose: The purpose of this study was to review articles and theses on Korean nursing students' stress, identifying overall research trends regarding such stress and suggesting strategies for stress management and nursing education system. Methods: The subjects for this study were 31 articles selected from three databases according to specific inclusion criteria. Results: Twenty-seven articles described survey research and four articles reported on experiments. Twenty-two studies related to stress from clinical practice among nursing students. Thirty-one articles reported on 40 regions and 44 colleges. Seventeen types of tools were used to measure nursing students' stress. The reported reliability of tools ranged from .76 to .96, and the mean score for nursing students' stress fell between 1.98 and 3.95. Conclusion: The findings from this review article indicate that nursing students exhibit different levels of stress as a result of school. Thus, they must learn to cope with stress to support their physical and psychological health. Moreover, finding ways to help student nurses handle job-related stress will require research related to the overall school, the curriculum, learning, and the life of nursing students, as well as stress intervention.

  • This study was undertaken to examine the knowledge about food culture and intakes of traditional food in Korean and Japanese elementary school students. In 2012 and 2013, a total of 265 students were surveyed, consisting of 73 Korean fifth graders and 192 Japanese sixth graders. The questionnaire comprised of queries on general items, the recognition and sampling of traditional and celebration foods, the knowledge about the partner country's food culture, and the frequency of consuming the partner country's foods. As a result of this study, the frequency of consuming their own country's traditional foods for Korean children (3.1 out of 5.0 points) and Japanese children (3.2 out of 5.0 points) was similar to each other. Japanese children reported to eat Korean foods (2.9 points) more frequently than those of Korean children to eat Japanese foods (2.4 out of 5.0 points) (p<0.001). However, the Korean children reported to have more experience on given typical Japanese foods than Japanese children reported about Korean foods. Further studies are needed for the perception on traditional foods in Korean and Japanese children. The results of this study can be used as a basic data to succeed and develop traditional food cultures.
