Medical Imaging field has great success in Medical Information System and come to the fore by the beginning of Radiology. However due to the medical imaging issue caused by improper information interface process, DICOM Standards Committee has begun to create standards and tried to improve the interoperability of medical imaging, which allow the application of medical imaging for various purposes. Despite the effort to control difficulties, dentistry field was in the blind zone from this standardization process that the mere development has been still resulted even though DICOM Standards Committee has recently added this field to set standards. Then it degrades not only the interoperation efficiency to other Medical Information System but also the major features of medical imaging in Dentistry field. Therefore, this paper will compare and analyze DICOM Conformance standards in general medical field. Rather than the former independent Dental diagnostic system, medical service industries are converging more and more. Therefore, I believe the system development to be DICOM Conformance status is the critical requirement to adapt for this change. 의료정보시스템에서 다루고 있는 정보 중 의료영상은 방사선학 의료분야를 시작으로 대두되고 발전해 왔다. 그러나 의료정보의 호환성 문제는 의료영상에도 동일하게 나타나게 되었으며 이를 개선하고자 DICOM 표준위원회에서 표준을 제정하고 의료영상의 상호운용을 향상시키기 위한 노력이 진행되어 왔다. 방사선학 의료분야를 시작으로 대두된 의료영상은 이후 다양한 일반 의학분야로 확대되고 있지만, 치의학 분야는 DICOM 표준의 사각지대에 놓여 있었다. 최근 DICOM 표준위원회에서 치의학 분야가 추가되어 개선되고 있으나 그 수준은 극히 미비한 단계이다. 이는 치의학 분야의 의료영상은 다른 의료정보시스템과의 상호운용을 저해할 뿐만 아니라 치의학 분야의 의료영상이 가져야 할 특성을 살리지 못하는 결과를 초래하는 결과를 가져오게 된다. 이러한 상황에서 치의학 분야의 의료영상의 DICOM 적합성을 살펴보고, 일반 의학분야의 DICOM 표준 적합성 수준과 비교 및 분석하고자 하였다. 과거와는 달리 치의학 분야의 진료형태가 독립적인 운영 형태에서 벗어나 의료 서비스 산업에 융합되고 있는 상황에서 일반 의학분야에서 확보하고 있는 DICOM 적합성 수준으로 향상시켜야 새롭게 변모하는 의료서비스 환경에서 살아갈 수 있을 것이다.

Top Bracing을 이용한 선박엔진의 진동방진에 관한연구

서성원 영남대학교 산업대학원 2010 국내석사

선박의 속도(Speed)와 엔진 출력이 높아짐에 따라 엔진의 크기가 전반적으로 커졌다. 특히 엔진의 높이 증가는 연소실 내의 폭발압력으로 인한 엔진 상부의 좌우 방향진동과 비틀림 진동을 더욱 심화시켰다. 다시 말해서, 연소실 내의 고압축 폭발압력은 Piston Head와 Rod를 밀어내고 Crosshead Guide Shoe로 전달된다. 이는 다시 Connecting Rod를 하강시키고 Crank Shaft를 회전시킴으로서 선박에 필요한 동력을 얻는 과정에서 Guide Shoe 부분의 측압과 Crank Shaft Journal부에서 받는 수직 반력에 의해 Main Engine의 진동이 발생되는데, 이 중에 Guide Shoe 부분의 측압은 가이드힘 모멘트 (Guide Force Moment)를 발생시킴으로서 엔진 상부를 좌우로 흔드는 H형 진동 모멘트와 엔진을 비트는 X형 진동모멘트가 발생된다. 따라서 이에 대한 대책으로 Main Engine과 Hull 구조물 사이에 Top Bracing을 설치한다. Top bracing에는 유압식(Hydraulic Type)과 마찰식(Friction Type)이 있다. 본 연구에서는 이들을 장착했을 때와 그 반대일 경우의 변화하는 Main Engine의 진동 양상과 선박에 미치는 영향을 파악하여, 각 엔진(MAN B&W사의 MC 엔진 전체)에 대한 적절한 Type의 Top bracing 적용기준을 명확히 하고, Top Bracing이 선체구조의 고유진동수(Natural Frequency)를 조절하여 공진이 회피되고 있음을 증명하고자 한다. 더불어, Top bracing 설치를 강력히 추천하고 있는 MAN B&W사의 권고 사항을 재정립함으로서, 선주들의 Top Bracing 설치여부에 대한 Comment를 조기에 종결시킬 수 있을 것으로 기대된다. Generally, size of main engines got bigger as its output and vessels’ speed increases. Especially, the increased height of engines made upper part’s and torsional vibration serious as the explosive pressure of chamber. In other words, the high explosive pressure of chamber pushes the piston head and rod and transmit to cross head guide shoe. It pushes down connecting rod and turns crank shaft and make power for vessel. During this process, the side force on guide shoe and the vertical counter force on crank shaft journal cause the vibration on main engine fig.1 engine section, and the side pressure on guide shoe rises the guide force moment that causes H vibration moment and X vibration moment. To prevent this, Top bracings are installed between the main engine and the hull structure. Top bracing has Hydraulic type and friction type. This study is to clarify the type and applying standard for each engine type (all MAN B&W-MC engines) and prove that top bracing controls natural frequency of hull structure to avoid critical vibration by studying condition with or without top bracings. Further more, it is expected to tie up arguments with owner’s concerning with installation of top bracing by clarifying the ecommendation of MAN B&W who recommends installation of top bracing.

This paper deal with the electromagnetic analysis and experimental verification of a double-sided permanent magnet linear synchronous generator (PMLSG) with slotted stator windings. Magnetizations of the permanent magnets (PMs) were initially expressed by a Fourier series expansion using a two-dimensional (2-D) coordinate system for use in a no-load magnetic field analysis. Analytical solutions were derived based on Poisson and Laplace equations and appropriate boundary conditions. The magnetic field distributions were then obtained. An induced voltage equation for a sinusoidal moving translator was derived from the no-load magnetic field solutions. To analyze the generating characteristics, it was essential to predict the equivalent circuit components. The resistance of winding was derived by considering the shape. To calculate inductance of winding, it was necessary to analyze the armature reaction field. A no-load magnetic field analysis was conducted according to a series of steps for the purpose of performing armature reaction field calculations. Inductances were then predicted on the basis of the armature reaction field calculation. Finally, the generating characteristics of the PMLSG were determined by an equivalent circuit analysis and compared with those of other types of generators. All of the analysis results were verified by comparison with the results of FEA and experiments. Also, this paper considered the reduction of the detent force PMLSG. The detent force, which is caused by energy imbalances owing to the interaction between tooth-slot structures and the PMs, must be minimized for start-up operation. Therefore, in this paper, suggest reduce methods. In this study, the detent force of a PMLSG was analyzed using FEA. This study will accelerate similar analyses and designs for other applications.

순천지역어의 음운현상에 대한 사회언어학적연구

This writer to look into the change in phonological system phonology of Sunchon Woldeung regional dialect, according to sociolinguistic factors such as generation and gender. As a result we have researched so far, regardless of generation gap, the regional dialect in this area includes 19 consonant phonemes, that is, /p/, /p^h/, /p'/, /t/, /t^h/, /t'/, /c/, /c^h/, /c'/, /s/, /s'/, /k/, /k^h/, /k'/, /h/, /m/, /n/, /ŋ/, /l/. This is consistent with the consonant system of the central language. In the vowel system, unlike the consonant system, it shows much difference between the aged and young generations. Since /e/, /ε/, /u¨/ and /o¨/ are phonetically well distinguished in the vowel phonemes of the aged people, there exist 10 vowels, that is, /i/, /e/, /ε/, /u¨/, /o¨/, /□/, /□/, /a/, /u/, /o/. However, among the young people, /o¨/ and /u¨/ are realized as a diphthong, [wE] or [wi], or as a single vowel, [E] or [i], and /e/ and /ε/ are realized as a merged sound, /E/ as they are rapidly integrating phenomenon. Therefore, the young people in this area have 7 vowels, /i/, /E/, /□/, /□/, /a/, /u/, /o/. Only two, /y/ and /w/ are realizedamong the gliding vowel(semi-vowel) system. Also in the vowels length, the young people are already confused between long and short sound, or they are even much losing the length, and this is a nationwide phenomenon. However, among the aged people, the length plays its function as discriminating quality. Next, let us consider the phonology. The Umlaut phenomenon(vowel-fronting), which has been actively realized in southern dialects, is also actively realized among the aged people in this area. However, as a standard language education has been generalized through school education or mass media among the young people, they come to have a recognition that a dialect is inferior to a standard language and not a quality language, and thereby it has been extremely limited and realized. And, the glottalization in the beginning of words belonged to /k/ family has been actively realized, and it is more notable in the native tongue rather than in Chinese words. In addition, its realization rate is higher in the aged people rather than in the young people. For palatalization, /k/ and /h/ families are perfectly realized in the aged people, and they are hardly realized in the young people. But, as a few of young people intentionally use the palatalized vocabularies, they are showing the sense of superiority, belonging and ties. Finally, in the language attitude research for the speakers in this area, 75% of the respondents answered that they have to gradually change their language to Seoul language. In addition, in the change of regional dialect by generation in this area, the aged people are using it as all of them know it, and the young people didn't use it at all. This means that they are gradually losing their regional dialect.

서성원 공주대학교 대학원 2015 국내박사

This study examines the concept and strategy of smart- learning and collaborative problem solving learning theory; this study elicits the examples of design-based research through the educational problems related to an instructional model for collaborative problem solving based on smart-learning in the actual schools. Based on this data, this study suggests the instructional model as an educational intervention in order to solve educational problems in the actual schools by offering an instructional model for collaborative problem solving based on smart learning, which is developed through a design-based research study. The present study investigates the following questions: 1. What are the problems faced by teachers who implement effective teaching and learning in the changing smart education environment?: what is the educational intervention? 2. What are the processes and elements of an instructional model for collaborative problem solving based on smart education as an educational intervention, which is designed to counteract found in the classroom and literature review. 3. How can the instructional model be administered which is designed to be an intervention to solve the educational problems in the classroom? An articulated Proto type was designed by Bannan-Ritland as an educational intervention based on earlier research.; The Delphi survey was used to evaluate the effectiveness of Bannan-Ritland’s articulated proto type. The first instructional model for collaborative problem-solving based on smart education was developed on the basis that Bannan-Ritland’s articulated Proto type is valid. The subjects for this study were two class of 5th graders at an Elementary school in a medium size city. The instructional design was used for each topic of the first model: the appropriateness of the instructional design was evaluated by one instructional design professor, one instructional design expert, one expert for smart education, and two teaching instructors. The first instructional model was revised according to results of formative testing and teaching experts' examination of it. Using the same process, instructional plans and materials for instruction were designed and offered to teaching instructors. The survey for learning satisfaction and learning effect was examined after for the second instructional model applied. The subjects were satisfied with the second instructional model with the majority of students giving an average score of 3.57 to 4.71 out of 5.00 points. In fact, the formative testing was terminated. It was decided that the development of the final instructional model would be completed, and would be revised without the need to implement formative testing repeatedly although there were additional problems and a few aspects to be improved in the instructional model for collaborative problem solving based on smart education. This final version of the instructional model consisted of three parts: Pre-Activity, Main-Activity, and Post-Activity. In this study, there were six stages within the instructional model for collaborative problem-solving based on smart education; 1) preparation stage to implement pre-activity, 2) cognition stage to confirm the learning objectives, the learning task, and role division, 3) co-exploration stage to collect, research, and share data, 4) collaboration stage to select, develop, and devise the solution, 5) co-sharing stage to share the solution, and 6) sympathy stage to reflect continuous output of learning and offer feed-back to both individual and group after class. In addition, it mentioned the specific characteristics and strategies of each stage. It described the devices and functions used during each stage in detail. Considerations to administer effectively the instructional model for collaborative problem-solving based on smart education as an educational intervention were suggested respectively; learning environment, learning target, preparation for learner, learning contents, e.t.c. To summarize, there are significant educational perspectives that this study of an instructional model for collaborative problem-solving based on smart education highlights. First, an educational intervention that solves educational problems in the classroom was developed which has recently gaining significance in the new educational environment. Second, this study suggested the combination of the practical collaborative instructional model with specific smart features and strategies. Third, this study indicated using various collaborative strategies and smart functions in order to implement an instructional model for collaborative problem-solving based on smart education as an educational intervention through design-based research. Fourth, this study identified processes, guidelines, and considerations of an instructional model, offering teachers a model that can be of practical use in the classroom.
