Purpose: The purpose of this study was to retrospectively evaluate the effect of 'Blocking Kirschner Wire (K-Wire) Technique', which has been developed to reduce protrusion of the lateral wall, in maintaining the level of reduction through clinical and radiological outcomes. Materials and Methods: Twenty-two patients with displaced intra-articular calcaneal fractures who used the blocking K-wire to maintain reduction (group A) and 44 patients that did not use blocking K-wire and were paired in 1:2 ratio with those Group A patients (group B), between January 2015 and December 2017 were enrolled in the study. All surgical procedures were performed via the extended sinus tarsi approach, and internal fixation using cannulated screws, Steinmann pins and K-wires was performed. American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot scale and postoperative recovery of exercise ability were compared for postoperative clinical outcomes. The radiological results were compared the Böhler angle, Gissane angle, calcaneal height and width, step off of posterior calcaneal joint, and the degree of protrusion of the lateral wall. Moreover, postoperative complications in both groups were compared. Results: There were no significant differences in the clinical outcomes of the two groups (p=0.924, p=0.961). The amount of Böhler angle, Gissane angle, calcaneal height and width, and step off of posterior calcaneal joint from the radiological results was not significantly different between the two groups (p=0.170, p=0.441, p=0.230, p=0.266, and p=0.400). However, the degree of protrusion of the lateral wall was 1.78 mm and 4.95 mm in group A and group B, respectively, and the difference between the two groups was significant (p=0.017). Although sural nerve entrapment and painful exostosis were more frequent in group B, they were occurred in a non-significant manner (p=0.293, p=0.655). Conclusion: Most of the clinical and radiological results as well as the complications were not significantly different between the two groups. However, the degree of protrusion of the calcaneus lateral wall in group A was promising. The 'Blocking K-Wires Technique' established by the authors may be an effective surgical option for maintaining the reduction of the lateral wall protrusion in displaced intraarticular calcaneal fractures.

Purpose: This study evaluated the long term clinical and radiographic results and the survival rates of unicompartmental knee arthroplasty (UKA). In addition, the factors affecting the survival of the procedure were analyzed and the survival curve was compared according to the affecting factors. Materials and Methods: Ninety-nine cases of UKA performed between December 1982 and January 1996 were involved: 10 cases with Modular II, 44 cases with Microloc, and 45 cases with Allegretto prostheses. The mean follow-up period was 16.5 years. Clinically, the hospital for special surgery (HSS) scoring system and the range of motion (ROM) were evaluated. Radiographically, the femorotibial angle (FTA) was measured. The survival rate was analyzed using the Kaplan-Meier method. Cox regression analysis was used to identify the factors affecting the survival according to age, sex, body mass index, preoperative diagnosis, and type of implant. The Kaplan-Meier survival curves were compared according to the factors affecting the survival of UKA. Results: The overall average HSS score and ROM was 57.7 and 134.3° preoperatively, 92.7 and 138.4° at 1 year postoperatively, and 79.1 and 138.4° at the last follow-up (p<0.001, respectively). The overall average FTA was varus 0.8° preoperatively, valgus 4.1° at postoperative 2 weeks, and valgus 3.0° at the last follow-up. The overall 5-, 10-, 15- and 20-year survival rates were 91.8%, 82.9%, 71.0%, and 67.0%, respectively. The factors affecting the survival were the age and type of implant. The risk of the failure decreased with age (hazard ratio=0.933). The Microloc group was more hazardous than the other prostheses (hazard ratio=0.202, 0.430, respectively). The survival curve in the patients below 60 years of age was significantly lower than those of the patients over 60 years of age (p=0.003); the survival curve of the Microloc group was lower compared to the Modular II and Allegretto groups (p=0.025). Conclusion: The long-term clinical and radiographic results and survival of UKA using old fixed bearing prostheses were satisfactory. The selection of appropriate patient and prosthesis will be important for the long term survival of the UKA procedure.

The dried rhizomes and roots of Gentiana scabra (GS) have been frequently prescribed as a traditional folk medicine in East Asia (including China, Japan, and Korea) for the treatment of various pathophy-siological conditions, such as inflammatory skin diseases, anorexia, indigestion, gastric infections, and diabetes mellitus. In the present study, the effects of aqueous (GS-W) and ethanolic (GS-E) extracts of GS on gastrointestinal (GI) motor function were investigated by measuring the in vivo gastric emptying rate (GER) and the intestinal transit rate (ITR) in mice. The GER was significantly increased by GS-W at a dose of 1 g/kg. The ITR was significantly increased by GS-W (at doses of 0.1 and 1 g/kg) or GS-E (at a dose of 1 g/kg) in a dose-dependent manner. Furthermore, the ITR value of GS-W (at a dose of 1 g/kg) appeared to be higher than that of cisapride, which was the most prominent prokinetic agent in the 1900s but was removed from the market in 2000 due to its fatal side effects. The above results suggest that GS-W might be a potential prokinetic agent to replace cisapride.

The aims of this study were to use the Rydoraku test, electrogastrography, and enterotachography to examine the presence of familial gastric dysmotility among monozygotic twins and their mothers; to determine the relationship between the symptoms and the indexes of the Rydoraku test, electrogastrography, and enterotachography; and to observe the therapeutic reaction for each differential treatment between twins with familial gastric dysmotility. The same herbal medication (Banhasasim-tang extract three times/day and Sojuckkunbi-tang extract three times/day) was given to each twin, but the younger twin also underwent manual acupuncture on the CV 10, 12, and 13 points of the abdominal wall and electrical stimulation of both ST 36 points of the lower leg 2-3 times per week. Evaluation of the therapeutic effect was followed after six weeks. The presence of familial gastric dysmotility was shown in the autonomic nerve system and gastric muscle and was thought to be a common pathophysiology induced by genetic co-ownership. Only the younger twin showed any marked relief of the dyspeptic symptoms associated with improvement of pyloric sphincter function, which was induced by acupuncture treatment. The Rydoraku test, electrogastrography, and enterotachography results showed the presence of familial gastric dysmotility. Although Korean traditional medicine had no effect on the familiar gastric dysmotility associated with genetic influences, the acupuncture treatment had a beneficial effect on the secondary disorder of pyloric sphincter function, which is associated with the relief of dyspeptic symptoms.

A numerical model is established in order to simulate the storm surges which were observed in the seas around Korea during typhoon and winter storm periods. The typhoons are Brenda (1985), Vera (1986) and Thelma (1987). the winter storm period is January 1-6, 1986. The simulated surges for the typhoon periods show good agreements with the recorded ones for the periods at the Korean coasts, but those for the winter storm show fair agreements in general tendencies, not in details. The model simulation in open sea shows a positive sea level near the typhoon center and a native sea level behind the typhoon. the positive surge seems to be due to the low pressure near a typhoon center and the negative on due to the wind stresses of the typhoon. The negative sea level is usually in the form of an elongated gyre. In the gyre, there is a cyclonic circulation of sea water, in which the pressure gradient force induced by the circular depression of the sea surface is balanced by the Coriolis force in readjusting stage.

In this study, the authors aimed to give careful consideration to the circulation of bioenergy (Qi) by using cardiorespiratory massage technique. Finding enlightenment in harmony with nature thousands of years ago, our ancestors created Qi using natural breathing and tried to achieve good health and long life by controling the up and down movement. Experiencing the importance of the abdomen during the hungry times, also, grandmothers cured diseases by rubbing the abdomen, which is the ocean of life with their soft, soothing touch of hand. Naval breathing therapy was formed, based on natural breathing, emotional recognition of grandmothers' soft, soothing touch, and the Theory of Unified Reason and Energy that is the key of Oriental medicine. Natural breathing and Yakson massage are kinds of naturopathy to change body and mind, cure diseases naturally, and maintain the improvement in physical functions by taking care of the abdomen through the creation of Qi and the up and down movement and keeping dynamic balance between the natural world and the inside and outside of human body. It is anticipated that this study could contribute to the practical spread for an active application of naval breathing therapy and be broadly used in scientific clinical researches.
