        임베디드 시스템 (Embedded System)은 모든 전자 산업에 있어서 또 하나의 첨병으로써 떠오르게 되었다. 90년대부터 지금에 이르기까지 고성능 전자장치 에서 소규모 가전에까지 임베디드 시스템이 적용되지 않은 분야를 찾아보기 어려울 정도이다. 각종 전자 제품이 고성능, 소형화를 추구하고 제품 본연의 기능은 물론이고 사용자 위주의 각종 부대기능을 제공하기에 이른 것이다. 예를 들어 초기 휴대전화의 본연의 기능인 음성 신호 전달에서 벗어나 MP3 Player와 카메라 기능, DMB(DigitalMultimediaBroadcasting)수신 기능까지 그 기능은 비약적인 발전을 가져 왔다. 본 논문에서는 ARM9 CoreCPU에 WindowsCE를 탑재한 Handheld PC를 개발하고 레지스트리 값을 Flash memory에 저장하는 방법에 대해 연구 하여 그 기능을 확인 하였다. 먼저 ARM920T Core 기반의 삼성 S3C2410X를 이용해 System board를 설계하고 Handheld PC기능 구현을 위해 임베디드 운영체제인 Windows CE. NET 4. 2를 포팅 하였으며, 이러한 과정이 논문에 기술되어 있다. 다음으로 이렇게 구성된 System을 이용해 사용자가 변경한 시스템의 중요 매개 변수들의 값을 Flash memory에 저장하여 다음 부팅시에도 이 값이 적용되도록 하는 방법에 대해 조사하고 각각의 장단점을 비교 하여 이를 개선하는 연구를 진행 하였다. 그리고 본 논문은 Handheld PC 설계과정과 레지스트리 저장 방법 중 하나인 RAM-Based레지스트리 저장 방법의 단점을 개선하는 연구를 기술한다. Over whole electrical business, Embedded system has risen as a spearhead. From 1990 to today, Embedded system adopted field can be observed at everywhere extending from small range of home electrics to high-tech electric equipments. All kinds of electric equipments become to be High technical and slim and supply the value added functions including its basic function. As an example, the main performance of the old mobile phone transferred voice signal as a basic functionality. Nowadays, the basic functionality of mobile phone has been increasingly developed including MP3 player, digital camera and even L)MB(Digital Multimedia Broadcasting) reception. On this research, we developed Handheld PC installed ARMS Core CPU with Windows CE, and studied how to store the registry value to Flash Memory, then finally confirmed the functionality. At first, we designed System board using ARM920T Core based SAMSUNG S3C2410X and ported embedded operating system of Windows CE.NET 4.2 to operate Handheld PC function. The procedure is described on the research. As the next step. we studied the method. We study how to apply the same system main parameter values that are saved on Flash memory at the next booting after user changed. This research is describing the design procedure for Handheld PC and how to improve the weak point of the RAM-Based registry storage method that is one of registry storage methods.

      • 영어의 Tough-구문에 관한 연구

        The purpose of this thesis is to study the semantic and syntactic characteristics of Tough-construction. It also examines different kinds of analysis on Tough-construction. Tough-construction has been studied since the beginning of transformational generative grammar. However it has not yet been properly investigated. Before my investigation of Tough-construction, I studied and summarized GB theory of Chomsky (1981) to examine different kinds of Tough-constructions on the basis of GB theory. To begin with, I examined the semantic characteristics of Tough-predicates. They are very emotive, that is, they include a speaker's subjective, emotive and evaluative response on a proposition. Next I examined the syntactic characteristics of Tough-construction. There were a few distinct syntactic characteristics such as the following: in Tough-construction the object of the complement clause is always an empty category; in Tough-construction the subject of the complement clause must also be an empty category; and in Tough-construction the matrix subject can't be an argument because it doesn't take ɵ-role from the matrix predicates. Also I examined some important analyses of Tough-construction. In early transformational generative grammar there are two analyses: Tough-Movement Analysis (TMA) and Tough-Deletion Analysis (TDA). In TMA they argue that the matrix subject is moved from the object position of the complement clause. In TDA they argue that the co-referential matrix subject and the complement object are base-generated in a D-structure and the co-referential complement object is deleted. The attempt to relate the matrix subject with the complement object causes some problems. In TMA the 't', trace of movement, is NP-trace, and it belongs to an anaphor, which should be bound within its governing category by the Binding Condition A. However, the NP-trace can't find its binder which makes it bound within the complement clause, its governing category, and thus it violates Binding Condition A. With regard to Case Theory, Case should not be given to NP-trace but the 't' in the TMA takes a Case. In TDA the matrix subject in the deep structure can't take any ɵ-role from the Tough-predicates ,which raises a serious problem that the matrix subject doesn't take a qualification as an argument. Chomsky(1977) said the WH-movement analysis could solve the problems somewhat by trying not to relate the matrix subject with the complement object. It uses an indirect way to be related with each other: the WH-movement and the Predication Rule. In deep structure the complement object's position is occupied by WH-items. After the WH-movement, the complement becomes an open proposition to which we can apply the Predication Rule. As this open proposition plays the role of a kind of predicate, the matrix subject and complement clause are in a subject-predicate relation. By the subject-predicate relation the matrix subject and the object gap in the complement clause can have a co-referential relationship to each other. For the stand of GB Theory, WH-movement analysis also violates the ɵ-criterion because the matrix subject is assumed to be base-generated as in Tough-Deletion Analysis. The Empty Operator Analysis is when the complement gap is a variable bound by an empty operator in the position of the Specifier of the complement CP. This empty operator doesn't have any inherent value or range and it must take its value or range from other component by the condition of a variable: 'A variable must be strongly bound(Chomsky 1986)'. The antecedent of the empty operator is determined by the rule of predication as in WH-movement Analysis. The first problem is that when the matrix subject is inserted in a D-structure, it violates the ɵ-criterion because the matrix subject in D-structure is an ɵ̅-position. Secondly even if the matrix subject is inserted in a S-structure it also violates the ɵ-criterion since the position of matrix subject in the S-structure is not a ɵ-position without being a reanalyzed AP as in the Reanalysis. Chomsky (1981) proposed Reanalysis for the explanation of Tough-construction. He argued that the matrix adjective and the complement CP, except trace-t (object gap), should be reformed as a complex adjective (AP). After reanalysis, trace-t is related with the matrix subject directly, that is, it is regarded as a kind of anaphor binding since the matrix sentence become a governing category of trace-t, and within the category trace-t is bound by a matrix subject. But Inserting the matrix subject in the D-structure causes a serious problem under the GB Theory. If the matrix subject, an argument, is inserted in the D-structure, it can't take an ɵ-role from the Tough-predicates. That is, it can't fulfill the role of an argument. Chomsky suggested that the matrix subject should be inserted in the S-structure. But it also creates a problem such that inserting the matrix subject in S-structure is only allowed in Tough-construction when it is different from all other common constructions in which the matrix subject is inserted in the D-structure. We can confirm that all previous studies on Tough-construction have some theoretical problems by examining Tough-construction. I know it is never easy to make a good explanation for a proper analysis on Tough-construction. Finally I've recognized that we need to study Tough-construction much more. Through successive research, I expect, someday we'll get a better result in Tough-construction research.

        골반에 관련된 질환으로 3차원 골반 CT 검사 시 정확한 자세를 취하기 위해서는 다리를 내측으로 15°회전시킨 상태로 유지해야 한다. 현재 사용하고 있는 보조기구로는 정확한 자세를 취하기 어려워 보조슈즈를 제작하게 되었으며, 3차원 골반 CT검사를 시행한 후 보조기구를 사용한 검사와 영상을 비교분석하여 진단의 유용성을 평가하였다. 보조슈즈의 유용성을 알아보기 위하여 2013년 1월부터 2014년 9월까지 보조기구를 사용한 38명과 보조슈즈를 사용한 42명으로 연령은 만 9세에서 89세 환자를 대상으로 하였다. 영상평가는 정성적 분석방법으로 영상의학과 의사 1명, 정형외과 의사 1명, 10년 이상 근무한 방사선사 1명이 영상을 분석하여 리커트 5점 척도법으로 평가하였고 SPSS 22.0을 이용하여 통계분석을 실시하였다. 영상평가의 결과는 보조기구를 사용한 환자에서 아주 나쁨 16(14.0%), 나쁨 9 (7.9%), 보통 18(15.8%), 좋음 36(31.6%), 아주 좋음 35(30.7%)로 나타났고, 보조슈즈를 착용한 환자에서 아주 나쁨 2(1.6%), 나쁨 8(6.3%), 보통 23(18.3%), 좋음 40(31.8%), 아주 좋음 53(42.0%)으로 나타났다. 통계분석에서 성별에 따른 보조기구와 보조슈즈의 차이점을 살펴보기 위한 독립표본 t-test에서는 보조기구에서 남자의 평균이 3.41, 여자의 평균이 3.72, 보조슈즈에서 남자의 평균이 4.03, 여자의 평균이 3.96으로 두 집단 간의 유의한 차이는 없는 것으로 나타났다(p>0.05). 연령별 보조기구 및 보조슈즈의 차이점을 살펴보기 위해 일원배치 분산분석을 하였고 사후검정으로는 R-E-G-W F를 실시하였는데, 보조기구에서 20~59세 이하의 평균이 3.82, 20세 이하의 평균이 3.67, 60세 이상의 평균이 2.67로 나타났고 60세 이상과 20~59세 이하에서 유의한 차이가 있는 것으로 나타났으며(p<0.05), 보조슈즈에서는 유의한 차이가 없는 것으로 나타났다(p>0.05). 보조기구와 보조슈즈를 사용한 환자군의 평균비교를 살펴보기 위한 독립표본 t-test에서는 보조기구에서 평균이 3.57, 보조슈즈에서 평균이 4.06으로 두 집단 간의 유의한 차이가 있는 것으로 나타났다(p<0.05). 보조기구와 보조슈즈에 대한 만족도의 관계를 알아보기 위한 대응표본 t-test에서는 착용감, 고관절 골절 환자의 착용, 통증, 조작의 편의성에서 보조슈즈 사용 유·무에 따라 집단 간의 유의한 차이가 있는 것으로 나타났다(p<0.05). 이와 같이 본 연구 결과 보조슈즈가 보조기구보다 통계적으로 유의한 차이를 보여 환자를 검사하는데 유용성이 있는 것으로 나타났다. 따라서 본 연구에서 제작한 보조슈즈는 검사하는 동안 환자 움직임에 의한 단점을 보완하여 정확한 자세로 검사하는데 최적이라 생각되고 검사의 신뢰성과 객관성을 유지할 수 있도록 환자 자세가 중요한 만큼 보조슈즈를 착용하여 검사하는 것이 바람직 할 것으로 사료된다. In 3D pelvic CT for related diseases of pelvic, the leg must be rotated inside by 15degrees to take the correct position. However, because currently used assistant device would be hard to take the exact position, I had to introduce new assistance shoes and then evaluate the diagnostic usefulness by comparing images of examination with conventional assistant device and newly developed assistance shoes. To survey usefulness of newly developed assistance shoes, this study objected 38patients who have experienced the examination with conventional assistant device and 42patients who have experienced the examination with newly developed assistance shoes from January 2013 to September 2014. Their age is from 9 to 89. Image evaluation were qualitatively analyzed in Likert 5 point scale (5: very good; 4:good; 3:usually; 2:poor; 1:very poor) by a orthopedic surgeon, a radiologist and a radiological technician who work over ten years with statistical analysis by using SPSS 22.0 Image assessment of patients with the conventional assistant device is very poor 16cases(14.0%), poor 9cases(7.9%), usually 18cases(15.8%), good 36cases(31.6%) and very good 35cases(30.7%) and patients with the newly developed assistance shoes are very poor 2cases(1.6%), poor 8cases(6.3%), usually 23cases(18.3%), good 40cases(31.8%) and very good 53cases(42.0%). To check the difference between conventional assistant device and new assistance shoes according to gender, when performing independent - Samples t-Test, in conventional assistant device, the average of male is 3.41 and female is 3.72 and in new assistance shoes the average of male is 4.01 and female is 3.96. There were no significant differences between the two groups (P>0.05). To identify the difference according to ages when performing one-way ANOVA and R-E-G-W F of post tests in conventional assistant device, the average of 20~59 years old is 3.82, under 20 years is 3.67 and over 60years is 2.67. There were significant differences between over 60years and 20~59 years old(P<0.05). There is a significant difference in conventional assistant device. To compare average of assistant device patient groups with average of assistant shoes patient groups when performing independent - Samples t-Test, the average of assistant device is 3.57 and the average of assistant shoes is 4.06. There were significant differences between two groups (P<0.05). To confirm relation of satisfaction about assistant device and shoes when performing paired t-Test, there were significant differences according to depending on the whether or not using the assistant shoes in wearing sensation, application of patients with hip fracture, pain and convenience of operation. The assistant shoes made in this study show assistant shoes has higher level of usefulness than the assistant device by showing a statistically significant difference. Because newly developed assistance shoes make up for disadvantages caused by patient movement, patients are able to take the exact position. It is important to maintain the correct position for reliable and objectivity of the examination, so I think it is preferable to wear the assistance shoes for examination.

        This study was conducted based on a survey targeting the chemical laboratory research workers of research institute within the company where safety matters are considered importantly among a variety of industry sectors. Based on the preliminary survey results, the workers were showing low safety consciousness compared to their high level of education and knowledge of major and this study was started in order to seek improvement measures on safety consciousness of research workers in chemical industry having higher risk compared to other industries. Through the survey, the study was conducted with a purpose of examining the general status related to safety of organization, an influence on the improvement of safety culture within the organization by the degree of safety consciousness of laboratory research workers, an influence on the improvement of safety culture by the safety behavior of organization, and verifying the mediating effect of safety behavior of organization in the relationship between the improvement of safety culture and the level of safety consciousness. When summarizing the main research results, the recognition on the importance of safety consciousness is known but the consciousness on prioritizing the safety is relatively low due to the performance-based organizational culture and requires fostering of safety cultural climate at the organizational level. The level of safety consciousness of researchers were shown to cause a positive influence on the improvement of safety culture of organization and the safety behaviors(safety management policies, systems, safety education and training) of organization were shown to mediate the relationship between the level safety consciousness and the improvement of safety culture of organization. When summarizing these results, the safety activities of organization can be known as a mandatory element in the degree of improvement of safety culture, and especially the factors of safety education activities, safety policies and management systems are a parameter that mediates the degree of improvement of safety consciousness and safety culture of researchers which are very important factors for reducing the industrial accidents through the improvement of safety culture. Therefore, in order to improve and develop the safety culture, it suggests that a multifaceted effort is required to provide the interaction between personal factors and organizational factors. Conclusively, by identifying the factors required for improving the safety culture within the organization, this study aims to contribute in the spread of safety culture through the improvement of safety consciousness of researchers in the chemical industry. 본 연구에서는 산업현장의 다양한 업종 중에서 안전부문이 중요하게 다루어지는 기업 내 부설연구소의 화학업종 실험실 연구종사자를 대상으로 설문조사를 토대로 연구하였으며 사전조사 결과 높은 학력과 전공지식에 비해 낮은 안전의식을 나타내고 있어 타 업종에 비해 위험성이 높은 화학업종의 연구원들의 안전의식 향상방안을 강구하고자 본 연구를 시작하게 되었다. 설문을 통해 조직의 안전관련 일반 현황을 살펴보고 실험실 연구종사자의 안전의식 수준이 조직 내 안전문화 향상에 어떠한 영향을 미치는가와 조직의 안전행동이 안전문화 향상에 미치는 영향 그리고 안전의식수준과 안전문화 향상과의 관계에서 조직의 안전행동의 매개효과를 검증하는데 목적을 가지고 연구하였으며 주요연구 결과를 요약해 보면 안전의식은 중요한 것은 알지만 성과주의 조직 문화로 아직 안전을 우선 시 하는 의식은 낮은 편이며 조직차원의 전반적인 안전문화 풍토 조성을 요구하고 있다. 연구원들의 안전의식 수준은 조직의 안전문화 향상에 정(+)의 영향을 미치는 것으로 나타났으며 조직의 안전행동(안전관리규정 및 체계, 안전교육 및 훈련)은 안전의식 수준과 조직의 안전문화 향상 사이에서의 관계를 매개하는 것으로 나타났다. 이러한 결과를 종합해보면 조직의 안전활동은 안전문화 향상정도에 필수적인 요소임을 알 수 있으며, 특히 안전교육활동과 안전규정 및 관리체계 요인은 연구원들의 안전의식 수준과 안전문화 향상정도를 매개하는 매개변수로서 안전문화 향상을 통한 산업재해 감소에 매우 중요한 요인임을 알 수가 있다. 따라서 안전문화를 향상시키고 발전시키기 위해서는 개인적 요인과 조직차원의 요인 간 상호작용을 할 수 있도록 다각적 노력이 필요함을 시사한다. 결과적으로 본 연구를 통해 조직 내 전반적인 안전문화 향상을 위해 필요한 요인들을 파악하여 화학업종의 연구원들의 안전의식 향상을 통한 안전문화 확산에 기여하고자 한다.
