Objectives : The aims of this study were to evaluate a blister caused by cupping. Methods : We searched relevant case reports, survey, and review articles using databases of online bibliography. Results : 1. The fluid in the blister caused by cupping therapy is normal substance by laboratory analysis. The fluid has no signs of infection in the culture, Gram stain, or tissue biopsy 2. In histological finding, the blister caused by cupping therapy is made by dermo-epidermal seperation at subcellular level. Suction blistering was neither inflammatory nor autolysis activation of lysosomal hydrolases. 3. Blistering times directly, related to suction pressure. Suction blister formation time is accelerated in older subjects compared with younger individuals and higher temperature was more susceptable to the blister compared with lower temperature. The flexor aspect of forearm is a easy site for suction blister formation compared with leg and abdominal site. 4. Blister caused by cupping therapy is treated by regular and judicious changes of sterile dressing over several weeks. The vesicles healed well and left no visible scar. Conclusions : Blister caused by cupping therapy is artificially controlled by doctor``s therapeutic purpose. Blister is not histologically injurious to health and the blister is a natural concomitant after cupping therapy.

In this study is aerial photos and UAV(Unmanned Aerial Vehicle) images were used to analyzed the characteristics of depositional landform changes in the Geum river channels before and after the opening gate of Gongju weir. Based on the depositional landform classification result, the main stream and the bare land occupied most of the area in all periods, and also found that the main stream, mid-channel island, and sand bar occupied a greater degree of area increase or decrease compared to other landforms in the classification items. As a result of analyzing the characteristics of depositional landform changes before and after the opening gate of Gongju weir, it is judged that the depositional landforms have changed due to the decreased water level of the Geum river after the opening of the weir, the summer rainy season and typhoons, river stabilization after the effluence of Daecheong dam, supply and deposition of river sediments and fixation of vegetation. The results derived from this study can be used as basic data for the study of river depositional landforms and the establishment of management and conservation plans for the landforms in river channels.

Objectives : This study was designed to examine the effects of hyperbaric oxygen therapy on cerebral infarction. Methods : Fifty-five patients with acute or subacute cerebral infarction were classified into two groups, the study group and control group. The study group was treated by hyperbaric oxygen therapy(HBOT) for 2 weeks(5 times/week) and the control group wasn't treated by HBOT. We compared the score of National Institutes of Health Scale(NIHSS scale) between two groups. We subdivided the study group by TOAST classification and onset stage, and compared the results. All of this data was analyzed by statistical method. Results : The study group patients who were treated by hyperbaric oxygen therapy saw more improvement than the control group patients in NIHSS score, and there was significant consideration. Among the study group patients, we saw more improvement during the first week period than in the course of the second week, and there was significant consideration. Conclusion : These results suggest that hyperbaric oxygen therapy(HBOT) could be a useful medical treatment to treat cerebral infarction. Further studies are needed on more cases to make sure that hyperbaric oxygen therapy (HBOT) is surely effective for cerebral infarction.

목적: 두 차례의 전층각막이식 후 재차 이식 실패가 발생하여 데스메막박리 자동 각막내피층판이식술을 시행한 사례를 보고하고자 한다. 증례요약: 33세 인도 국적의 남자 환자로 우안 아메바각막염이 발생하여 인도에서 2차례 전층각막이식수술 및 각막윤부이식을 시행받은 후 본원에 내원하였다. 경과 관찰 도중 우안 이차성 녹내장 진단하에 아메드밸브이식술을 시행하였으며, 우안 각막신생혈관에 진행하여 우안 결막후전술 및 양막이식술을 시행하였다. 이후 각막이식 실패 상태로 진행하여 데스메막박리 각막내피층판이식술을 시행하였다. 수술 후 7개월째 우안 나안시력 20/320으로 특별한 합병증 없이 유지되고 있다. 결론: 전층각막이식 후 각막신생혈관 및 녹내장수술로 인한, 각막내피세포 부전으로 반복적인 이식 실패가 발생한 환자에 있어서 기질 상태가 양호할 경우 데스메막박리 자동 각막내피층판이식술을 시행하여 합병증 없이 좋은 시력회복을 보였기에 문헌고찰과 함께 보고하는 바이다. 추후 국내에서 더 많은 수술 환자를 대상으로 한 연구가 필요하다. Purpose: To report a case of Descemet stripping automated endothelial keratoplasty (DSAEK) for graft failure after re-penetrating keratoplasty (PK). Case summary: A 33-year-old man of Indian nationality who had developed right eye amoeba keratitis and had received two penetrating keratoplasties and allogeneic kerato-limbal transplant in India sought treatment at our hospital. During the follow-up, Ahmed valve transplantation was performed under the diagnosis of secondary glaucoma in his right eye; the patient also underwent conjunctival recession and conjunctival permanent amniotic membrane transplantation as corneal neovascularization had progressed. Subsequently, the corneal transplantation failed and DSAEK was performed. At 7 months after the operation, the right-eye visual acuity was 20/320 without any complications. Conclusions: DSAEK may restore good vision without complications in patients with repeated corneal graft failure after PK from corneal endothelial cell failure followed by corneal neovascularization and glaucoma surgery but with good stromal conditions. We present this case, along with a review of the literature. Future studies will require more surgical patients.

This study modified the properties and boundaries of the inland wetland types through the structural edit of the National Wetland DB, and analyzed the characteristics of the different land cover by area and the entire inland wetlands of South Korea. The inland wetlands of the Gangwon Basin had a small area of waters. In addition, the ratio of natural barren was high, reflecting the characteristics of the upper reaches of the large river in the east and west part of Gangwon Province. The Geum River Basin had a high percentage of aggregate land due to the development of large alluvial land, and the ratio of artistic barren was low, so various ecosystem service of wetland elements were distributed evenly. The Nakdong River Basin had a high proportion of waters as water level in the channel rose due to the installation of 4 Major Rivers Beam, and the ratio of Natural barren was low. Moreover, the water level of the main attributes flowing into the Nakdong River drainage system was not high, so the ratio of vegetation concentration was high. The Yeongsan River Basin showed that Waters had the high proportion. And the distribution of Natural barrens represented differently according to the Yeongsan River Basin and the Seomjin River Basin. Finally, Sand and Gravels supplied to rivers during precipitation were deposited in the main stream of the Han River Basin, and the differences between the side and high side was large in the area, reflecting the characteristics of the mouth of a river, so the Natural barren of Clay was distributed.

이 연구는 가사보며 노래부르기 과업으로 브로카 실어증자의 읽기와 조음능력을 향상 시키고자 하였다. 3명의 브로카 실어증 대상자로 하였으며 연구 방법은 사전-사후 검사를 사용하였다. 이 연구에서 사용된 노래부르기 과업은 3단계로 구성되어있다. 노래는 대상자에게 있어 익숙한 노래 5곡을 선정하였다. 1단계는 제공된 MP3파일로 노래를 들으며 따라부르기를 한다. 2단계는 문자단서로 제공된 노래가사를 한 음절씩 짚으며 따라 부르기를 하고, 3단계에서는 음을 점진적으로 제거하며 가사 읽기를 시도한다. 이에 치료실외에서도 하루에 3회씩 연습할 수 있도록 지도하였다. 그 결과 노래부르기 과업은 읽기, 조음능력 뿐만 아니라 따라말하기, 이름대기 등 전반적인 언어능력에 있어 향상을 보였다. The purpose of this research was to explore the effect of singing while reading the lyrics had on the reading and articulation skills of people with Broca’s aphasia. The study consisted of three subjects with Broca’s aphasia and the results were analysed by pre-to-post analysis. Thirdly, through the implementation of the task of singing, linguistic abilities, such as reading, intonation, word-repeating and naming skills were all improved. The five songs that were chosen were songs that the participants were familiar with. The first stag involved participants singing along to the songs that were given to them as an MP3 file. The second stage involved participants looking at the hard copy of the lyrics and then breaking up each syllable while singing out loud and the third stage involved gradually omitting the tone from the songs and getting participants to only read the lyrics out loud. Participants were advised to repeat these three steps three times a day outside of the treatment room. The results of this study are as follows: Firstly, there was an improvement in the reading skills following singing tasks. Secondly, through implementing the task of singing there was an articulation in the clarity of intonation. Thirdly, through the implementation of the task of singing, improvements in reading, the ability to intonate, repeating words and naming skills were evident; as well as an overall improvement to the linguistic ability of the people.
