We present a case of a 68-year-old female with an atypical form of spinal tuberculosis, which involved posterior elements with multiple foci in two noncontiguous vertebral levels. The lesions caused spastic paraparesis and urinary hesitation. There was no evidence of pulmonary or other extrapulmonary tuberculous disease. Based on clinical and radiographic findings, this atypical spinal tuberculosis was preoperatively misdiagnosed as metastatic spine tumor. The histopathologic finding confirmed tuberculosis and the patient was treated successfully with surgery and antituberculous therapy. In case of a spinal lesion of unknown origin, it is important to be aware that atypical spinal tuberculosis can mimic metastatic spine tumor and tuberculosis should always be considered.

This study investigates how the truth-related words in Korean, which were originally noun or adverb with 'truth' related meaning, can be used as discourse markers with the functions such as 'emphatic marker', 'attention getter', or 'hesitation marker', and it argues that such functions of the discourse markers are the result of grammaticalization process. That is to say that the truth-related words have acquired new functions as discourse markers from their corresponding lexical items as a noun or an adverb through grammaticalization process. In this study, we demonstrate that the truth-related words tend to appear sentence-initially or sentence-medially when they are used as discourse markers. We also show that they are most likely to be used as emphatic marker because of the lexical meaning of the truth-related words. Finally, we state that truth-related words differ from one another in where they appear and what function they are used with.

본 연구의 목적은 기존 자동심장충격기인 T-AED와 새롭게 개발된 SC-AED의 제세동 신속성 및 사용자가 느끼는 주관적 편의성을 비교하는 것이다. 2017년 2월부터 2018년 4월까지 전남지역의 D대학, C대학병원의 기본인명소생술 교육센터에서 의료종사자 및 일반인을 위한 기본소생술과정에 참여한 156명을 T-AED (n = 77) 및 SC-AED (n = 79) 그룹에 무작위할당 하였다. 각 그룹은 제세동을 실시한 후, 총 제세동 지연시간, 제세동 지연시간, 쇼크버튼 누름 지연시간, 후속 흉부압박 재개시간까지의 시간을 측정하였고 이를 t-검정을 통해 분석했다. 실험 후 조작자신감, 사용편의성, 의사결정 도움, 이상 3가지 요인에 대한 자료를 설문으로 수집하였고 각각 t-검정을 통해 분석하였다. SC-AED는 T-AED와 비교하여 총 제세동 지연시간(11.22 초), 제세동 지연시간(11.04 초) 및 쇼크버튼 누름지연시간(2.15 초)가 현저히 단축되었습니다 (p<0.001). 주관적 편의성 측면에서 자신감(T-AED : 7.62±1.25VAS vs. SC-AED : 7.80±0.98VAS, p = .358)는 중요하지 않았지만, 편의성(T-AED : 7.05±1.36VAS vs. SC) -AED : 8.95±0.89VAS, p<0.001) 및 의사결정도움(T-AED : 6.58 ± 1.73VAS vs. SC-AED : 9.08±0.98VAS, p = 0.001)은 유의한 차이를 보여주었다. 결론적으로 T-AED에 비해 의료종사자 및 일반인 집단 모두에서 더욱 신속한 제세동을 가능하게 하였으며, 사용자의 편의성과 명확한 의사결정을 크게 도와주었다. SC-AED에 적용된 기술이 향후 보편적인 자동심장충격기에 상용화된다면 더욱 효과적인 PAD를 통해 심정지 환자의 생존율 제고에도 이바지할 것이다.

본고의 목적은 기예르모 델 토로의 <판의 미로>(2006)를 환상영화로 평가하게 해주는 특성과 그것에 밀접하게 결부되어 나타나는 미궁의 모티프의 의미와 기능을 고찰하는 데 있다. 츠베탕 토도로프는 '환상적인 것'을 현실에 침입한 초자연적인 사건에 직면하여 자연적 해석과 초자연적 해석 사이에서 겪는 망설임이라고 정의하였는데, <판의 미로>는 그 망설임이 사라져 환상적인 것이 '기이'장르나 '경이'장르로 들어가도록 하지 않고 그 상태가 그대로 유지되도록 하기 때문에 이 영화에서는 환상성이 계속해서 잘 드러난다. 이때 미궁은 환상계로 들어가는 통로이자 그것을 대표하는 공간으로서 예술을 상징한다. 로즈메리 잭슨은 환상이 "문화적 속박으로부터 비롯된 결핍을 보상하려고 하는 욕망의 문학"이어서 무의식적 제재들을 반복적으로 다룬다고 보았는데, 델 토로의 영화는 환상 세계에서 가족 로맨스가 이루어지도록 함으로써 욕망의 표현으로서의 환상의 특성을 잘 보여준다. 이때 미궁은 욕망의 장소로서 마음을 상징한다. 캐스린 흄은 환상이 미메시스와 같이 현실에 대한 반응이자 '일치된 현실로부터의 이탈'이라고 정의하였는데, 이 영화는 '비전'장르로서 '대조'의 방법을 통해 환상계가 현실계를 비추도록 함으로써 그 정의를 충족시키고 그것이 가진 환상성을 돋보이게 한다. 이때 미궁은 현실계의 거울로서 세계를 상징한다. 이처럼 <판의 미로>는 환상적인 것이 매우 효과적으로 기능한다는 점에서 환상영화를 대표할 만하며, 이 영화에 나타난 미궁은 예술, 세계, 마음의 세 가지를 모두 상징하여 의미가 충만한 모티프라고 평가할 수 있다. 본고의 의의는 위와 같은 고찰을 통해 한 모티프가 특정 장르에서 작용하는 방식을 조명한 데 있다.

No one really doubts that the hottest area of dentistry in 21st century would most likely be 'implant'. With the support of a vast amount of research, implant has been successfully and rapidly absorbed into the field of general dentistry including private practitioners. For teeth with hopeless(or refractory) periodontitis or periapical pathosis, with no hesitation most dentists would think extraction as the sole treatment option followed by prosthodontic replacement possibly including implant. Not many dentists would take Trasplantation/Replantation as another treatment option for a particular condition. Dentistry is often more focused on 'Restoration' than 'Preservation' of natural dentition. 'Biologic Implant' is obviously much closer to the concept of 'Preservation'. Many different types of biologic implant system have been introduced to clinical dentistry so far. Many of those have failed to earn reasonable acknowledgement despite of the clinical success they brought. For some reason biologic implant has rather been alienated for long time. RPI(Ring Pin Implant) is designed to improve the prognosis and success rate of transplanted/replanted teeth. RPI is a Ti-based custom made implant system. It is fabricated either by electric casting or milling process. The major feature RPI gas is the 'ring & hole' structure. The hole should be no less than 1mm diameter to allow bone bridge formation thru it. The ring structure and bone bridge formation creates anti-torque activity, which largely increases the 'initial stability' of the transplanted/replanted teeth. It is also reported that RPI is beneficial in the aspect of resisting root resorption following replantation/transplantation procedure.

Application of gas assisted injection molding has been expanded during last two decades because of many advantages such as design flexibility, dimensional stability, reduction of machine tonnages, and so on. However, the surface defects including hesitation mark and gloss difference are observed for thick parts. Difficulties in lay-out of the gas channel and processing condition are another disadvantages. Liquid gas assisted injection molding(LGAIM), in which a liquid with a boiling point lower than the temperature of the polymer melt is injected into the melt stream, and travels with the melt into the mold where it vaporizes and pushes the melt downstream and against the cavity walls to create hollow channels within the part, is a good alternative of the conventional gas assisted injection molding especially in manufacturing simple and very thick parts. Though this is a new frontier of the innovation in the injection molding industry, there is no guideline for the design and processing conditions. In this paper, theoretical analysis has been made to describe the hollow formation dynamics in LGAIM. This model provides an insight into LGAIM process: explains why LGAIM has advantages over conventional gas assisted injection molding, and gives a guideline for the design and processing conditions.

A 51 year-old male was admitted with the chief complaints of swallowing difficulty and pain on neck and upper chest for 2 months prior to admission: He was taken biopsy under esophagoscopy, and the result was squamous cell carcinoma. Preoperatively we studied the esophagogram and chest CT. On these, we found the main appreciable mass at midesophagus easily. But, we missed the upper cervical unexpected mass. So we performed the esophagectomy and lymph node dissection from upper clavicle level to the esophagogastric junction by thoracic approach as wide as possible, and cervical esophagostomy and feeding gastrostomy also. At that evening we reviewed the studied films in detail, and we found another mass lesion at C4-C6 level of cervical esophagus. We performed the 2nd operation e.g. cervical esophagectomy on next morning without hesitation. Between these two masses, there was almostly normally looking skip area grossly. The squamous cell carcinoma of the esophagus could be multicentric in character and may have skip area. But, we heard little reports until now. The two masses could be different in origin or be same probably by submucosal spreading. Anyway, it was an alarming case to the surgeon not to neglect the another possible lesions in squamous cell type. Postoperative course was uneventful, he took G-tube feeding with no problems on 7th postoperative day. Now he took the postoperative irradiation at out patient department.

Purpose: This study attempted to describe the essential structure of male students' experience as nursing majors. Method: The data were collected through the in-depth interviews of seven male students majoring in nursing. The analysis of data were made using phenomenological analytic method suggested by Colaizzi(1978). Result: In this study, five essential themes emerged. They are: $\ulcorner$Strong initial -though subsequently declining- hesitation over choice of major$\lrcorner$, $\ulcorner$Challenging, ongoing effort to survive in an environment of new and unaccustomed experiences and relationships$\lrcorner$, $\ulcorner$Recurring sense of reassurance and relief upon occasions of unexpected success$\lrcorner$, $\ulcorner$Growing internalization and acceptance of their role as nursing students or as future nurses$\lrcorner$, $\ulcorner$Ambivalent feelings resulting from the contradiction between their vision concerning their future as nurses and their worry concerning their future as male nurses$\lrcorner$Conclusion: With an increasing number of male students majoring in nursing, this study will prove helpful not only in understanding male students' experience while majoring in nursing but also in describing their needs for systemic and emotional support.

Multimodal medical image fusion is the process of retrieving valuable information from medical images. The primary goal of medical image fusion is to combine several images obtained from various sources into a distinct image suitable for improved diagnosis. Complexity in medical images is higher, and many soft computing methods are applied by researchers to process them. Intuitionistic fuzzy sets are more appropriate for medical images because the images have many uncertainties. In this paper, a new method, based on Sugeno's intuitionistic fuzzy set (SIFS), is proposed. First, medical images are converted into Sugeno's intuitionistic fuzzy image (SIFI). An exponential intuitionistic fuzzy entropy calculates the optimum values of membership, non-membership, and hesitation degree functions. Then, the two SIFIs are disintegrated into image blocks for calculating the count of blackness and whiteness of the blocks. Finally, the fused image is rebuilt from the recombination of SIFI image blocks. The efficiency of the use of SIFS in multimodal medical image fusion is demonstrated on several pairs of images and the results are compared with existing studies in recent literature.
