Purpose: To evaluate outcome and morbidity in patients with vulvar cancer treated with radiotherapy, concurrent chemoradiotherapy or postoperative radiotherapy. Materials and Methods: The records of 24 patients treated with radiotherapy for vulvar cancer between July 1993 and September 2009 were retrospectively reviewed. All patients received once daily 1.8-4 Gy fractions external beam radiotherapy to median 51.2 Gy (range, 19.8 to 81.6 Gy) on pelvis and inguinal nodes. Seven patients were treated with primary concurrent chemoradiotherapy, one patient was treated with primary radiotherapy alone, four patients received palliative radiotherapy, and twelve patients were treated with postoperative radiotherapy. Results: Twenty patients were eligible for response evaluation. Response rate was 55% (11/20). The 5-year disease free survival was 42.2% and 5-year overall survival was 46.2%, respectively. Fifty percent (12/24) experienced with acute skin complications of grade III or more during radiotherapy. Late complications were found in 8 patients. 50% (6/12) of patients treated with lymph node dissection experienced severe late complications. One patient died of sepsis from lymphedema. However, only 16.6% (2/12) of patients treated with primary radiotherapy developed late complications. Conclusion: Outcome of patients with vulvar cancer treated with radiotherapy showed relatively good local control and low recurrence. Severe late toxicities remained higher in patients treated with both node dissection and radiotherapy.

This study was performed from March to September 1997 on 95 healthy students to observe the effects of acupuncture at Hap-kok (LI4) according to the meridian and qi-xue(氣血) phenomenon of oriental medicine's theory. Skin temperature on the Hap-kok (LI4) and Chun-Choo (ST25) were measured by D. 1. T. I. (Digital Infrared Thermograph Imaging) before acupuncture stimulation and 1min, 10 min after acupuncture stimulation. 1. In healthy students, the left and right mean temperature of LI4 and ST25 was $29.04\;^{\circ}C,\;29.12\;^{\cir}C\;and\;30.29\;^{\circ}C,\;30.22\;^{\circ}C$ respectively. 2. In control group, the time dependent changes for 10 min of LI4 and ST25 were $-0.32\;^{\circ}C,\;-0.36\;^{\circ}C\;and\;-0.5\;^{\circ}C,\;-0.46\;^{\circ}C$ respectively, however, the thermal differences of both sides LI4 and ST25 were not changed for 10 min. 3. In acupuncture stimulation of both sides LI4, the time dependent changes of ST25 were $-0.13\;^{\circ}C,\;-0.06\;^{\circ}C$, and the thermal differences of both sides ST25 were reduced, but not changed significantly. In acupuncture stimulation of right side LI4, the time dependent changes of LI4 were $-0.1\;^{\circ}C,\;-0.32\;^{\circ}C$ respectively, and the thermal differences of both sides LI4 were increased more than control, but not significantly. Also, that of ST25 were changed by $-0.69\;^{\circ}C,\;-0.63\;^{\circ}C$ respectively, but not significantly. 4. In acupuncture stimulation group, it was classified following the thermal differences of both sides LI4 and ST25, and the effects of acupuncture were observed by changes of classification. The acupuncture of both sides LI4 results in temperature of the left side ST25 to be high after acupuncture. The acupuncture of right side LI4 results in increased ratio of the left side higher than right LI4. The above results indicates that D. I. T. I. was a useful method to observe follow-up the effects and changes by acupuncture stimulation on objective evaluation of phenomenon for the meridian system. Thus, acupuncture on LI4 affects to thermal changes of ST25 and LI4, but exact examination of thermal changes on ST25 will have to be.

This paper explains analytical and experimental studies to evaluate the natural frequency of a composite carbody of Korean tilting train. The composite carbody with length of 23m was manufactured as a sandwich structure composed of 40mm-thick aluminium honeycomb core and 5mm-thick woven fabric carbon/epoxy face. From the finite element analysis, the 1st bending and 1st twisting natural frequency of the composite carbody were 11.67Hz and 14.4Hz, respectively. In order to verify the analytical results, the natural frequency measuring tests were performed. The measured 1st bending and twisting natural frequencies of the composite carbody were 10.25Hz and 11.0Hz, respectively. Both of these results satisfied the design requirement.

A 21-year-old male visited our emergency room. He could not remember the mechanism of injury. He was found beside a motorcycle. Initial vital sign was stable. Observation and conservative treatment were planned at the intensive care unit (ICU). On the third day at ICU, he complained sudden flank pain. It was colicky and hard to control. Without the pain, he had no specific symptom, sign, or laboratory findings. On computed tomography, renal pelvis was filled with hematoma which induced hydronephrosis. Double-J catheter and percutaneous nephrostomy was implemented by an intervention radiologist. Hematome in the renal pelvis was aspirated during the procedure. Symptom of the patient was subsided after the procedure. He was discharged without specific complications.

We present a case of a colonic involvement associated with necrotizing pancreatitis, with a review of the literature. A 10 year old boy had an appendectomy at the local clinic ten days ago. On admission, he complained nausea, vomiting and severe constipation. His abdomen was distended and he had tenderness on the left abdomen. Laboratory and radiologic studies revealed findings consistent with acute pancreatitis with colonic complication. He was treated conservatively for 30 days but did not improve. On hospital 30th day, abdominal pain developed and his vital sign changed. Abdominal CT suggested ischemic change of the transverse colon. At laparotomy, the left colon showed stenosis. The greatly distended transverse colon was resected and a transverse end colostomy was done. He was discharged at postoperative 45th day with improvement and colostomy closure was performed 8 months later.

This paper is a follow up study of [2]. In this paper we analyse the contents of middle school mathematics textbooks published in the 1st National Curriculum Period centered on the concept 'straight line' and discuss how they are different from contemporary mathematics textbooks in view of connectedness of contents, mathematical terms, textbook as a learning material vs. teaching material, relationship between contents of national curriculum and textbooks, and some topics related to direct proportion, function, method of equivalence as a method for solving simultaneous linear equations and so on. The results of our analysis and discussion suggest implications for reforming mathematics curriculum and developing mathematics textbooks.

We report here a case of oral myiasis in the Republic of Korea. The patient was a 37-year-old man with a 30-year history of Becker's muscular dystrophy. He was intubated due to dyspnea 8 days prior to admission to an intensive care unit (ICU). A few hours after the ICU admission, 43 fly larvae were found during suction of the oral cavity. All maggots were identified as the third instars of Lucilia sericata (Diptera: Calliphoridae) by morphology. We discussed on the characteristics of myiasis acquired in Korea, including the infection risk and predisposing factors.

The potential for enhancing myocardial protection by adding high-energy phosphate to cardioplegic solutions [St. Thomas Hospital solution] was investigated in a rat heart model of cardiopulmonary bypass and ischemic arrest. Creatine phosphate was evaluated as an additive to the St. Thomas Hospital cardioplegic solution. Creatine phosphate 10.0 mmol/L as the optimal concentration which improved recovery of aortic flow and cardiac output after a 30 minute period of normothermic [37oC] ischemic arrest. In comparing mechanical function in both groups the mean postischemic recoveries of aortic flow, cardiac output, stroke volume and stroke work [expressed as a percentage of its preischemic control] were significantly greater in STH-CP group than in CP- free control group. In addition to improving function and decreasing CK release, CP reduced reperfusion arrhythmias significantly decreasing the time between cross-clamp removal and return to regular rhythm from 81.8 * 13.9 [sec] in CP-free group to 35.9 * 6.8 [sec] in CP group [P< 0.05] so, exogenous CP exerts potent protective and antiarrhythmic effects when added to the St. Thomas Hospital cardioplegic solution. However, the mechanism of action remains to be elucidated.
