Purpose: We evaluated the clinical results of arthroscopic ACL reconstruction using quadrupled hamstring tendon with tibial remnant-preserving technique. Materials and Methods: Thirty-five cases were evaluated from Feb, 2003 to May, 2006. The average interval from injury to surgery was $2.6{\pm}1.6$ months. The cause of injury was mostly sports-related trauma. The average follow-up period was 17 months. Tibial remnant was preserved as much as possible and caution was taken not to damage the remnant during ACL reconstruction. Postoperative rehabilitation was the same as the usual rehabilitation method after ACL reconstruction, except for delaying motion for 2 weeks with an extension locking brace. Clinical evaluation was performed using ROM; Lachman test; pivot-shift test; anterior displacement measurement using KT-2000 arthrometer; Lysholm score and proprioception measured by single limb standing test. Results: There was no limitation of knee motion without contracture. The Lachman test and pivot-shift test were both negative. The side-to-side difference of anterior displacement measured using KT-2000 arthrometer was improved from 6.7 mm to 2.2 mm. The average Lysholm score improved from 81 to 96. The single limb standing test for proprioceptive evaluation showed no significant difference from a normal leg. Conclusion: ACL reconstruction with tibial remnant-preserving technique can preserve mechanoreceptors with prorioception and expect good functional recovery.

Purpose: We evaluated the minimal 1 year follow-up results (shoulder stability and the clinical and functional results) for the Remplissage technique to fill a Hill-Sachs lesion. Materials and Methods: The subjects were 12 patients who could be followed up for more than 12 months after the "Remplissage" procedures in our hospital from December 2008 to November 2009. Their mean age was 27.9 years old and the mean follow-up was 19 months. The evaluations included the ROM, the ASES score, the KSSI score, the ROWE score and postoperative MRI. Results: On the postoperative functional evaluation after an average of 16 months, the ASES score improved from 50.8 preoperatively to 78.3 postoperatively, the KSSI score improved form 44.5 preoperatively to 81.0 postoperatively and the ROWE score improved from 40.2 preoperatively to 84.3 postoperatively. After an average 14 months for all the cases, the range of movement was nearly in the normal range, which is 178.6${\pm}$18.6 (165~180) degrees for forward flexion and 49.3${\pm}$10 (43~60) degrees for external rotation. Conclusion: For recurrent shoulder instability with a large Hill-Sachs lesion, the Remplissage technique has a good outcome after more than 1 year follow-up in terms of the shoulder stability and the clinical and functional results.

Background: The purpose of this study is to describe the characteristics of malpractice claims related to hemopneumothorax and to identify the causes and potential preventability of such claims. Material and Method: A retrospective study was performed by reviewing the records in the Lawnb website and Lx CD-rom: the records on closed malpractice claims involving hemopneumothorax were abstracted from the files available for analysis. The records were reviewed and were analysed to determine the etiology of hemopneumothorax, patient age, results of lawsuit and indemnity payment, underlying diseases, cause of death or complications, and the factors associated with a successful defense. Result: Seven closed claim involving hemopneumothorax were founded in the data for malpractice. Three claims were supreme court decision, one was a high court decision and three claims were district court decision. The most common cause of death was tension pneumothorax. Four of which resulted in indemnity payments. Conclusion: While malpractice claims involving hemopneumothorax were uncommon, they resulted in a high rate and amount of indemnity payments. Claims are more common in pediatric patients. In case of iatrogenic hemopneumothorax, post-procedural X-ray can improve patient outcome and is also associated with decreased indemnity risks. Informed consent is also important.

The percentage of moisture content in rice before harvest is crucial to reduce the economic loss in terms of yield, quality and drying cost. This paper discusses the application of artificial neural network (ANN) in developing a reliable prediction model using the low altitude fixed-wing unmanned air vehicle (UAV) based reflectance value of green, red, and NIR and statistical moisture content data. A comparison between the actual statistical data and the predicted data was performed to evaluate the performance of the model. The correlation coefficient (R) is 0.862 and the mean absolute percentage error (MAPE) is 0.914% indicate a very good accuracy of the model to predict the moisture content in rice before harvest. The model predicted values are matched well with the measured values($R^2=0.743$, and Nash-Sutcliffe Efficiency = 0.730). The model results are very promising and show the reliable potential to predict moisture content with the error of prediction less than 7%. This model might be potentially helpful for the rice production system in the field of precision agriculture (PA).

Gymnophalkides seoi has drawn medical attentions since the discovery of the first human case and a highly endemic area on a southwestern coastal island of Shinan- gun, Korea. Marine bivalves especially oysters were strongly suspected as the source of infection. In this study the oysters, Crassostrea girns, naturally produced (rom the endemic area were examined whether they contain gymnophallid metacercariae. All of 50 oysters examined were infected with the metacercaviae of a gymnophallid, with the metacercarial density per oyster of 610 on average (2-4,792 in range). Later they were identified as G. seoi by obtaining adult worms from experimental mice. The metacercariae were unencysted, and firmly attached on the mantle surface of the oysters with their oral sucker. In sectioned specimens they were equipped with the ventral pit, a peculiar organ of the genus Gymophalloides, and non-muscular genital pore which was connected dorsally to the seminal vesicle. The seminal vesicle was in a great majority mono-sac. By this study, it has been confirmed that the oyster is a 2nd intermediate host of G. seoi as well as the major source of human infection with this fluke.

The pigments of three old and new celestial charts folding screens(『Celestial Chart(Folding Screen)』 and 『Old and New Celestial Charts, Eight-Panel Folding Screen』 of National Folk Museum of Korea and 『Koudou-Nanboku-Ryousouseizu』 of National Diet Library of Japan) were analyzed to estimate their dating. It was estimated that the 『Celestial Charts(Folding Screen)』 was painted using traditional pigments from the Joseon dynasty such as azurite, indigo lake, malachite, atacamite, vermilion, iron oxide, cochineal, gamboge, orpiment, lead white, talc and soot. The green and blue colors of the 『Old and New Celestial Charts, Eight-Panel Folding Screen』 and 『Koudou-Nanboku-Ryousouseizu』 were painted using artificial inorganic pigments such as emerald green and ultramarine blue. These pigments were imported from Europe post the mid-19th century. In the 『Old and New Celestial Chart, Eight-Panel Folding Screen』, only artificial inorganic pigments were used for green and blue colors. However in the 『Koudou-Nanboku-Ryousouseizu』, emerald green and atacamite in green color, and ultramarine blue and indigo lake in blue color were used together. Based on both the results of pigment analysis and the study of star charts and inscriptions, the 『Celestial Charts(Folding Screen)』 was painted post mid-18th century. The 『Koudou-Nanboku-Ryousouseizu』 and 『Old and New Celestial Charts, Eight-Panel Folding Screen』 were painted after green and blue artificial pigments were imported in the mid-19th century. The 『Koudou-Nanboku-Ryousouseizu』 in which both traditional and western artificial pigments were used, can be dated earlier than the 『Old and New Celestial Chart, Eight-Panel Folding Screen』.

This study was introduced the short-term effectiveness of Oriental medicine treatment for lumbar disc herniation inpatients. We selected 208 inpatients with a magnetic resonance imaging(MRI)-confirmed lumbar disc herniation since June 2012 until August 2012. Their demographics characterisitics, numeric rating scale(NRS) and Oswestry back-related disability index(ODI) for low or leg pain, lumbar flexion and extension angle were assessed at baseline and when discharged from the hospital. When it measured the straight leg raisingscale(SLR), the low side of the angle was examined. Treatment every patient has received as follow; herbal medicine, bee venom, acupuncture and physical examination, spinal manipulation. NRS of low back pain and leg pain and ODI is $5.6{\pm}2.3$, $4.9{\pm}2.8$ and $45.5{\pm}20.0$, respectively at baseline and $2.8{\pm}1.8$, $2.7{\pm}1.9$ and $27.2{\pm}14.1$, respectively when discharged from the hospital. range of motion(ROM) of lumbar flexion and extension angle and SLR is $70.0{\pm}27.1$, $15.4{\pm}7.2$ and $61.3{\pm}23.0$ respectively at baseline and $80.5{\pm}16.9$, $18.25{\pm}4.1$ and $73.2{\pm}14.0$, respectively when discharged from the hospital. It shows that statistically significant improved(P<0.001). Furthermore, regarding patient satisfaction with the treatment, excellent(33.7%), good(55.4%), normal(10.4%), poor(0.5%), it suggests that most patients(89%) satisfied with the treatment.

The several Chinese herbs such as Soon-Ki-Hwal-Hyul-Tang, Bo-Yang-Hwan-O-Tang, Seong-Hyang-Jeong-Ki-San, So-Hap-Hyang-Won and O-Yak-Soon-Ki-San were extracted with water and then lyophilized. For identification of the effect of extracted herbs, they were medicated to 103 patients of cerebrovascular accident for 4 week. They were hospitalized in D-Oriental Medical Hospital from April to August in 1999. The herbs were extracted with water and lyophilized and then, used as samples. The medical history of each patient was detected and analyzed from their medical records. The results were as follows; 1) Each sample (Soon-Ki-Hwal-Hyul-Tang, Bo-Yang-Hwan-O-Tang, Seong-Hyang-Jeong-Ki-San, and O-Yak-Soon-Ki-San) was statistically significant differences of systolic blood pressure(t=4.22, P=0.0004; t=3.44, P=0.0028; t=2.11, P=0.0463; t=3.23, P=0.0052). The statistically significant difference of diastolic blood pressure showed by medicated with Soon-Ki-Hwal-Hyal-Tang, Seong-Hyang-Jeong-Ki-San, and O-Yak-Soon-ki-San (t=2.13, P=0.0459; t=2.68, P=0.0136; t=3.12, P=0.0066). 2) The statistically significant difference of the arm/leg-ROM showed by medicated with Soon-Ki-Hwal-Hyul-Tang, Bo-Yang-Hwan-O Tang, So-Hap-Hyang-Won(t=4.74/4.95, P=0.0002/0.0001; t=2.25/2.44, P=0.0368/0.0248; t=5.85/6.76, P=0.0001/0.0001). 3) In the verbal disorder, Soon-Ki-Hwal-Hyul-Tang, Bo-Yang-Hwan-O-Tang had statistically significant differences(t=4.50, P=0.0002; t=3.32, P=0.0036). 4) In the conscious disorder, Soon-Ki-Hwal-Hyul-Tang, Bo-Yang-Hwan-O-Tang, Seong-Hyang-Jeong-Ki-San, and So-Hap-Hyang-Won had statistically significant differences(t=6.32, P =0.0001; t=8.32, P=0.0001; t=3.74, P=0.0012; t=5.14, P=0.0001). 5) Bovine aortic endothelial cell (BAEC) were cultured in DMEM treating 0.01mg/ml, and 0.1mg/ml of each lyophilized samples for 24 hours. In BAECs were treated by 5 kinds of samples, the effect of So-Hyap-Hyang-Won induced syncytium of adjacent endothelial cells. It may induce the recovering of the damaged blood vessels in cerebrovascular accidental patient by angiogensis of endothelial cells. Therefore, it suggests that the medication of So-Hap-Hyang-Won will help to nursing care for cerebrovascular accidental patients.

The purpose of this study was to determine the effects of 5 weeks self-help management program on reducing depression, promoting Activity of Daily Livings(ADLs), Instrumental Activity of Daily Livings(IADLs), grasping power, hope and self-efficacy for post stroke patients visiting public health care centers in Seoul. This was pre-experimental study, and the subjects were 27 post stroke hemiplegic patients. The program was composed of five sessions and each session had health education on stroke, ROM exercise and recreation. Data were collected from May to November, 2000, and all subjects were asked to complete the Questionnaires, be measured vital signs and grasping power. Data were analyzed with frequency, percent, paired t-test, and Pearson's correlation coefficient using SAS(version 6.12) program. The results were as follows : 1) The scores of ADLs were increased from 27.04 to 28.22 after program, and that was statistically significant(p=.005). 2) The scores of IADLs were increased from 18.70 to 19.78 after program, and that was statistically significant(p=.004). 3) The grasping power of right hand were increased from 21.87kg to 26.93kg after program, and that was statistically significant(p=.002). But the grasping power of left hand were statistically insignificant(p=.919). 4) The scores of depression were decreased from 39.63 to 35.30 after program, and that was statistically significant(p=.030). 5) The scores of hope were increased from 30.89 to 34.15 after program, and that was statistically significant(p=.002). 6) The scores of self-efficacy were increased from 67.70 to 76.37 after program, and that was statistically significant(p=.000). According to the results of this study, the scores of Activity of Daily Livings(ADLs), Instrumental Activity of Daily Livings (IADLs), hope, and self-efficacy and the grasping power were improved and depression was reduced in post stroke patients participating in self-help management program. Therefore we recommend to use self-help management programs as a nursing intervention for the post stroke patient.
