Surgical therapy for adenocarcinoma of the esophagogastric junction II requires distal esophagectomy, in which a transhiatal management of the lower esophagus is critical. The 'dorsal track control' (DTC) maneuver presented here facilitates the atraumatic handling of the distal esophagus, in preparation for a circular-stapled esophagojejunostomy. It is based on a ventral semicircular incision in the distal esophagus, with an intact dorsal wall for traction control of the esophagus. The maneuver facilitates the proper placement of the purse-string suture, up to its tying (around the anvil), thus minimizing the manipulation of the remaining esophagus. Furthermore, the dorsally-exposed inner wall surface of the ventrally-opened esophagus serves as a guiding chute that eases anvil insertion into the esophageal lumen. We performed this novel technique in 21 cases, enabling a safe anastomosis up to 10 cm proximal to the Z-line. No anastomotic insufficiency was observed. The DTC technique improves high transhiatal esophagojejunostomy.

현재 국내 건축물은 일반주택, 빌라 등을 제외한 대부분의 건물에 소방시설을 적용하고 있다. 그렇지만 소방시설의 활용은 이천물류창고 화재, 코리아 냉동창고 화재, 대구지하철 참사와 최근 부산의 고층 오피스텔 화재 등을 볼 때 제대로 작동하지 않았다. 이처럼 실제 화재시 소방설비가 제대로 작동이 되지 않아 인명과 재산피해 등이 계속해서 발생되고 있다. 이에 본 연구에서는 소방시설 중 가장 널리 사용되고 초기 소화에 중요하게 사용되는 옥내소화전의 관리 실태를 파악하고 그것에 대한 문제점을 데이터화하여 실제 화재시 소방시설의 적극적인 활용을 위한 해결점을 찾고자 한다.

The purpose of this study is to analyze the records of 8 people with mental disabilities who had participated in Research and Mutual Help of Bethel's House and to investigate the occurrence of mental crisis and process of self-help by using the grounded theory method. As a result of axial coding, the central phenomenon of crisis experience of the people with mental disabilities was derived as 'being overwhelmed by hardships in the life related to their symptoms'. In the self-help process of overcoming the crisis, Action-interaction strategies were derived as 'talking about the hardships', 'researching and practicing with peers', 'participating in various groups', etc. through the intervening conditions such as 'understanding patterns and meanings of hardships led by the person' and 'finding ways to overcome the hardships with the person'. These strategies were analyzed as a process in which the person with mental disabilities leads his/her life reassuming control over his/her crisis. The result of this study shows that it is necessary to expand the political crisis concept in the support system for the mental crisis of people with mental disabilities, and the self-help approach in which the persons participate autonomously can be useful.

PURPOSE: The purpose of this study was to investigate the effects of task oriented circuit exercise(TOCE) on the balance and cognition in mild dementia patients. METHODS: The subjects of the study were 30 patients with mild dementia and assigned to the TOCE(task oriented circuit exercise) group(n=15) and aerobic exercise(AE) group(n=15). TOCE group performed six task three times weekly for 12 weeks. AE group underwent the cycle ergometer and treadmill exercise three times a week during the experimental period respectively. Timed up and go test(TUG), Berg balance scale(BBS) and AP1153 Biorescue were used to assess the parameters for the balance. Korean-mini mental state examination and Global deterioration scale(GDS) were used to assess the parameters for the cognition. For the statistical analysis, paired t-test and independent t-test were used to compare the differences among two groups. RESULTS: Each group showed improvement in balance and possibility for improving cognitive function. TOCE group especially, there were significant improvements in limit of stability. CONCLUSION: The results of the study suggest that TOCE is a more diverse exercise programs introduced in the study. Furthermore, TOCE can be a helpful to improve the balance and cognition in mild dementia patients.

Titanium alloy (Ti-alloy) is widely used as a material for core parts of aircraft structures and engines that require both lightweight and heat-resistant properties owing to their high specific stiffness. Most parts used in aircraft have I-, L-, and H-shaped thin-walled structures for weight reduction. It is difficult to machine thin-walled structures owing to vibrations and deformations during machining. In particular, cutting tool damage occurs in the corners of thin-walled structures owing to the rapid increase in cutting force and vibration, and machining quality deteriorates because of deep tool marks on machined surfaces. In this study, milling experiments were performed to derive an effective method for machining a L-shaped thin-walled structure with Ti-alloy (Ti-6Al-4V). Three types of machining experiment were performed. The surface quality, tool wear, cutting force, and vibration were analyzed comprehensively, and an effective machining method in terms of tool life and machining quality was derived.
