  • A 65-year-old male presented with pain in his right medial calf. An imaging study revealed no acute lesions, and a diagnosis of saphenous neuralgia was made by a nerve conduction study. He received temporary pain relief with saphenous nerve blocks twice in a one-week interval. Pulsed radiofrequency neuromodulation reduced pain to 10% of the maximal pain intensity. At 6 months after the procedure, the pain intensity was not aggravated even without medication. Pulsed radiofrequency neuromodulation of the saphenous nerve may offer an effective and minimally invasive treatment for patients with saphenous neuralgia who are refractory to conservative management.

  • PHILOS plate fixation in osteoporotic proximal humerus fracture of old age is well-known for high complication rate, especially metal failure, providing various augmentation techniques, such as calcium phosphate cement, allogenous or autologous bone graft. We report a case of polymethyl methacrylate augmentation to provide appropriate reduction with a significant mechanical support. This can be a treatment option for displaced unstable osteoporotic proximal humerus fracture with marked bony defect.

  • Adults of Chironomidae were collected at Soyang river sites in Chuncheon-si, Gangwon-do on 1 August and 14 September in 2008, and 1 May in 2009. A total of 794 adults were collected, consisting of 52 species, 23 genera, 4 subfamilies. Among them, 7 species were recorded in Korea for the first time, and 9 species were new to science. These 7 previously unrecorded and 9 new species are described with illustrations. Eight species still have not been identified. The subfamily Prodiamesinae and four genera: Demicryptochironomus, Parakiefferiella, Psectrocladius and Monodiamesa are the first record in Korea. Tanytarsus seohyoni n. sp. was the most dominant species, consisting of 24.6% of the total samples.

  • A Health Interview Survey at Chuncheon city was conducted to assess level of illness by stratified random sampling method. Sample size was 6,007 and the prevalence of illness in period of 15 days was studied. 1) Prevalence rate of illness among Chuncheon citizen was 20.8 percent, and that of acute condition was 10.8 percent and chronic condition, 10.0 percent. 2) There was significant difference in prevalence rate by sex, especially the prevalence rate of chronic illness. 3) High positive correlation was noted between aging and prevalence rate of chronic illness. But negative correlation was noted in case of acute illness. 4) Multiple regression analysis on morbid state by socioeconomic variables was not seen to be appropriate for this survey, especially the analysis of acute illness. 5) Estimation of anual prevalence rate could not be possible because of seasonal variation of disease prevalence.

  • According to the result obtained by the CIA analysis(A-CN-K and A-CNK-FM ternary diagram), the chemical weathering of granitic grus in Chuncheon basin is too weak, thus calcium and sodium may not be dissolved sufficiently, but go as far as to be more progress than that of Yeongju-Bonghwa basin, Jeongeup, Nonsan and Namwon, common granitic grus in Korean Peninsula. Therefore the chemical characteristics of granitic hills in Chuncheon basin show that granitic weathered mantles are not saprolite formed by alteration while this may be true for guns(sandy weathered mantles). The weathered mantles of inner hills in the basin is slightly altered, footslope of mountains are more altered, and footslope hills are undergone some alteration. But their alteration doesn't show any advances to saprolite, and most of them are still in incipient weathering stage.

  • Diabetic foot ulcers (DFUs) are among the most serious complications of diabetes and are a source of reduced quality of life and financial burden for the people involved. For effective DFU management, an evidence-based treatment strategy that considers the patient's clinical context and wound condition is required. This treatment strategy should include conventional practices (surgical debridement, antibiotics, vascular assessment, offloading, and amputation) coordinated by interdisciplinary DFU experts. In addition, several adjuvant therapies can be considered for nonhealing wounds. In this narrative review, we aim to highlight the current trends in DFU management and review the up-to-date guidelines.

  • The goal of the present work was to determine the optimal addition amounts of liquid smoke and curing mixture to develop Chuncheon Dakgalbi with improved preference and shelf-life. In the first experiment, Chuncheon Dakgalbi was prepared with different amounts of liquid smoke. In the second experiment Chuncheon Dakgalbi was prepared with various amounts of curing mixture and 0.1% (w/w) liquid smoke. Different amounts of liquid smoke resulted in different aroma patterns, which were observed using an electronic nose, and Dakgalbi with 0.1% (w/w) liquid smoke had the highest score in overall acceptability. The addition of liquid smoke and curing mixture inhibited the growth of bacteria, slowed down the decline in pH, and delayed increased in volatile basic nitrogen contents and lipid oxidation. However, no clear effects were observed on instrumental color. From a consumer preference test, the highest preference score was achieved by added 0.2% (w/w) curing mixture. Liquid smoke and curing mixture extended shelf-life and improved preference of Chuncheon Dakgalbi. Considering the physicochemical, microbiological and consumer preference, it was recommended to add 0.1% (w/w) liquid smoke and 0.2% (w/w) curing mixture to Chuncheon Dakgalbi to enhance shelf-life and preference.

  • Objective: The authors reviewed clinical and radiological outcomes in patients with three column injury of the cervical spine who had undergone posterior cervical fixation using Nitinol shape memory alloy loop in the anterior-posterior combined approach. Materials: Nine patients were surgically treated with anterior cervical fusion using an iliac bone graft and dynamic plate-screw system, and the posterior cervical fixation using Nitinol shape memory loop ($Davydov^{TM}$) at the same time. A retrospective review was performed. Clinical outcomes were assessed using the Frankel grading method. We reviewed the radiological parameters such as bony fusion rate, height of iliac bone graft strut, graft subsidence, cervical lordotic angle, and instrument related complication. Results: Single-level fusion was performed in five patients, and two-level fusion in four. Solid bone fusion was presented in all cases after surgery. The mean height of graft strut was significantly decreased from $20.46{\pm}9.97mm$ at immediate postoperative state to $18.87{\pm}8.60mm$ at the final follow-up period (p<0.05). The mean cervical lordotic angle decreased from $13.83{\pm}11.84^{\circ}$ to $11.37{\pm}6.03^{\circ}$ at the immediate postoperative state but then, increased to $24.39{\pm}9.83^{\circ}$ at the final follow-up period (p<0.05). There were no instrument related complications. Conclusion: We suggest that the posterior cervical fixation using Nitinol shape memory alloy loop may be a simple and useful method, and be one of treatment options in anterior-posterior combined approach for the patients with the three column injury of the cervical spine.

  • The purpose of this research is to reevaluate the success factors and significance of the battle through the analysis of the only successful Chuncheon district battle during the defense combat in the early part of the Korean War on June 25, 1950. The research results are the matters that are analyzed from the viewpoint of the armed forces of the Republic of Korea, focusing intensively on the successful aspect of the early defense combat against North Korean army's surprise invasion of the South and on the battle that thwarted the North Korean army's intensive surprise attack intention. This research attempts to reanalyze the Chuncheon District Battle in connection with the Kim Il-sung's strategic course of action in consideration of the operation plan of North Korean invasion of the South. In other words, it is to reanalyze the enemy tactics in connection with North Korean army's plan of invasion of the South. The fact that the 6th Division of the armed forces of the Republic of Korea destroyed the North Korean army's operations plans that were in accordance with Kim Il-sung's strategic plans has more significance than a simple tactical success. The Chuncheon District Battle should be reevaluated as the "decisive battle" which went beyond a successful early defense combat in a Chuncheon region, and which fundamentally defeated North Korean army's war plan itself by thwarting the Kim Il-sung's strategic plan.

  • We report major element chemistry of the Chuncheon amphibolite in the Precambrian Kyonggi massif and discuss its origin. On the basis of areal distribution and chemical difference, the Chuncheon amphibolite can be divided into the Gubongsan arnphibolite in the Gubongsan Group east of Chuncheon city and the Sangguli amphibolite in the Yongduri gneiss complex occurring to the southeast of the Gubongsan Group. Overall major element characteristics of the Chuncheon amphibolite indicate an igneous precursor, although it shows concordant relationship with metasedimentary rocks in many cases. The parental rock of the amphibolite has tholeiitic composition with 45-53wt% $SiO_2$. The Sangguli amphibolite has lower MgO than the Gubongsan one. The difference in $TiO_2$/P_2O_5 ratio between the two amphibolites suggests that they are not genetically related. In MgO variation diagrams, $Na_2O$, $Fe_2O_3$ and $Al_2O_3$ show scattered pattern, while MgO has positive correlation with CaO and negative one with $SiO_2$, $TiO_2$, $P-2O_5$ and $K_2O$. These variations can be interpreted as the result of differentiation of basaltic magma with fractionation of olivine, pyroxene, and plagioclase. Tectonic discrimination using major elements generally suggest withinplate environment for the Chuncheon amphibolite which is similar to that of the amphibolite in the Ogcheon belt.
