교장의 지도성 유형에 따른 도서지역 교사들의 직무 만족도 연구

조병수,정회욱 木浦大學校敎育硏究所 2005 교육연구 Vol.18 No.-

본 연구는 교사가 지각하는 학교장의 지도성 유형과 직무만족과의 관계를 알아보는데 있으며 구체적으로는 도서지역 학교장의 지도성 유형을 분석하여 보고, 학교 조직에서 학교장의 지도성은 교사의 배경변인(성별,학력별,경력별,연령별,직위별,학교그별,학교규모별)에 따라 어떻게 지각되고 있는지를 고찰한다. 학교현장의 문제를 기초로 도서지역 교사가 지각한 학교장의 지도성 유형과 교사의 직무만족과의 관계가 어떠한가를 교사들의 인식을 중심으로 재분석해 봄으로써 교사의 직무만족을 유도할 수 있는 바람직한 학교 행정가의 지도성 유형을 찾아보고자 하였다. 연구결과 도서지역 교사들은 학교장의 지도성을 목표지향성. 인간지향성, 관료 지향성 경향의 순으로 지각하고 있으며, 다음으로 교사가 지각한 직무만족도는 인간관계가 가장 중요한 요인이며 자아실현, 업무활동, 근무조건 순으로 나타났다. 또한, 학교장의 지도성 유형이 관료지향성인 경우에는 직무만족 하위요인들 중 인간관계와 직무자체가 부적인 상관이 있으며 그 외, 교사의 직무만족의 하위요인들은 학교장의 관료지향성과는 상관관계가 낮은 것으로 나타났다. 이러한 결과를 토대로 볼 때 도서지역에서 근무하는 교사들은 학교장에 대한 인간적인 측면에 관심을 더 갖고 있는 만큼 학교장의 지도성과 교사성취를 위한 소양교육이 필요하다 하겠고, 교사들이 즐겁고 보람된 교수 활동이 되기 위해서는 제도적 장치 및 행정적, 재정적 지원체제가 마련되어야 할 것으로 본다. This study is on the correlation berween the principals' leadership style that were perceivd by reachers and the degree of job satisfaction of teachers.Specifically this study is to analyze the principals' leadership style in island areas and to search how they are perceived by reacher's various factors such as sex, academic career, age, job-ranking. grade of school. scale of school etc. In other words. this study is to analyze the correlation between the principals' leadership style and the degree of job satisfaction of teachers and to search for the desirable model of executive teachers' leadership. The results are that teachers in island areas recognized the principals' leadership as goal-oriented, human-oriented. and bureaucracy oriented. And human-relation is the most important factor in the degree of job satisfaction and the realization if the ideal. work itself. and working, conditions are followed. If the principal has a bureaucratic leadership. human-relation and the work itself-among the surbordinate factors were shown to have a negative relation with it. The rest of factors showed a low relation with the principal"s bureaucratic leadership. If was appeared that the teachers in this area were more affected by the principal's human mature. There should be some educational programs for the principals'. the institutional device, and administrative and financial supporting system for teachers' better quality of life.

디지털 영상감상에 나타난 사용자 참여적 현상에 관한 연구 : 웹환경을 중심으로 Focused on the Web environment

김병욱 朝鮮大學校 社會科學硏究所 2002 社會科學硏究 Vol.23 No.1

디지털 영상의 활용이 급격히 증가하고 있는 가운데 기존의 디지털 영상표형은 표현의 기법중심으로 발전해 왔다고 할 수 있다. 그러나 디지털 영상이 감상 중심에서 웹을 기반으로 하는 표현매체를 통해 "영상의 사용"이라는 관점으로 변해가면서 그 활용이 다채로와 지고 있다. 영상에 있어서의 참여적 영상의 구현이 필요하게 되었고, 적극적인 사용자의 참여에 의한 매시지 전달의 효율성 극대화와 비선형구조의 스토리전개, 새로운 디지털 영상 미학의 창조 등 다양한 파급효과를 유발할 수 있는 가능성이 나타나고 있다. 이러한 상황에서 영상의 사용에서 발생할 수 있는 사용자와의 상호작용을 규명하고, 영상표현 자체에서의 사용자 참여 가능성을 살펴본다.

고분자 나노복합소재 제조 및 물성향상 연구

남병욱,황태원 한국기술교육대학교 2003 論文集 Vol.10 No.1

Nanocomposites are used as a new class of polymer system and many researchers have been interested in the clay nanocomposite because of its good mechanical properties, heat resistance, flame retardancy, and barrier property. Modified layered silicates as fillers are dispersed at a nanometer -level within a polymer matrix and then new extraordinary properties are observed. In this study, Polypropylene/clay nanocomposites were prepared in a twin screw extruder by the melt compounding method. In order to increase the compatibility of PP with the clay, the MAPP (MA=2.6%, Mw=49,600), was used as a compatibilizer. And organic modified clays were used as a nanometric filler during the melt extrusion. Through the analysis of SAXS, WAXS, the dispersion of clay was investigated. These nanocomposites compared with a neat Polypropylene/talc composite have high modulus, low toughness, and reduced shrinkage at the stable dispersion.

원화환율의 장기구매력평가에 관한 실증분석 : 부호검정법 Sign Unit Root Test

吳有珍,朴炳旭 한국국제경제학회 2004 국제경제연구 Vol.10 No.2

구매력평가관계의 성립의 여부는 국제금융이론에서 중요한 관심대상 중의 하나이다. 대표적인 실증분석 방법으로는 Dickey-Fuller류의 단위근 검정법을 사용해서 실질환율을 분석하는 것이다. 이런 검정법들은 낮은 검정력(power)과 최소자승법(Least squares method)에 기반하기 때문에 이상치(outlier)에 민감하다는 단점을 가지고 있다. 본 연구에서는 이런 단점을 보완하기 위하여 새로운 부호검정법(sign test)을 도입하였다. 부호검정법은 이상치와 정규가정을 만족하지 않는 자료의 경우에도 사용가능하도록 조건을 완화하여 낮은 검정력(power)을 향상시킨다. 본고에서는 미국, 영국, 독일, 캐나다, 그리고 일본 등 우리나라 주요 교역국들의 실증자료로 부호검정법과 기존의 Dickey-Fuller 검정의 결과를 비교분석 하였다. 분석기간은 외환위기 이후까지 포함한 전체 기간과 외환위기 이전까지의 기간으로 나누어서 검정을 시도하였으며, 분석결과 한국은 어느 국가와도 구매력평가관계가 성립되지 않았다. Purchasing power parity(PPP) is of interest in international finance literatures. The most popular method for testing PPP is the Dickey-Fuller(DF) test based on the ordinary least squares estimator(OLSE). The OLSE-based unit root tests, however, suffer from size distortion and power loss. We use a new sign unit root test which has simple exact null distribution and is robust to possible outliers from heavy-tailed errors. We also investigate whether PPP holds between Korea won and other currencies of important trade countries such as United States, the United Kingdom, Germany, Canada, and Japan by testing for unit roots in real exchange rates. We use Korean won as the base currency.

Stock price index type of housing price indices were commonly used in Korea. However, this type of indices are not suitable for Korean housing market experiencing rapid changes in stock including both new constructions and demolitions. Especially, the recent Korean housing market has experienced substantial changes in housing characteristics. Basically, the stock price index type of housing price index requires a constant survey stock over time in order to maintain the comparability in total housing values. However, the constant stock concept is hard to accept in the Korean housing market accompanying with rapid increase and qualitative changes in housing stock. An alternative is a hedonic price index. However, the basic data requirements for the application of the hedonic model cannot be fulfilled in the Korean housing market where actual sale information is mostly unknown. In order to overcome this structural deficiency, the price indices in Korea are based o periodical price survey with the help of real estate brokers. If we accept the assumption that the whole condominium units belonging to a basic survey unit (an area type in an condominium complex) share the same housing characteristics and the surveyed price, we can use the repeat sale index concept with some modifications. The persistent price survey generates a perfect form of repeat sales data. This paper proposes a practical method for the application of repeat sale index to condominium sales price indexing.

Variation of the Muscle Activity of Erector Spinalis and Multifidus According to Their Respective Cueing When Performing Tasks, Including Tactile Stimulation in Prone Position

Byeong-Uk Gam,송창호 물리치료재활과학회 2022 Physical therapy rehabilitation science Vol.11 No.1

Objective: Purpose of this study was to compare muscle activity ratio of multifidus to erector spinalis according to various cueing including tactile stimulation to provide an effective strategy to provide verbal and tactile feedback during exercise to provoke multifidus muscle activation. Design: Cross-sectional study. Methods: Participants of this study included 28 healthy adults. Muscle activities of the multifidus and erector spinalis were measured while the participants performed tasks according to the three different methods of verbal cueing and three different tactile stimulation. Surface EMG was used to measure the muscular activity of the muscles during all the tasks. Results: Tactile stimulation to abdomen and lumbar vertebrae showed no significant difference in the muscle activity ratio (p>0.05). However, muscle activity ratio of the multifidus in relation to the erector spinalis was increased when subjects were given verbal instructions to make lumbar curvature with little force and to make lumbar curvature while pulling navel (p<0.05). However, it was decreased when they were provided with verbal instruction to make lumbar curvature with strong force (p<0.05). Conclusions: According to the results, proper verbal instruction was an effective tool to increase the muscular activity of multifidus. This study aimed to find and provide the most appropriate verbal cueing while doing exercises to activate multifidus.

CutPaste-Based Anomaly Detection Model using Multi Scale Feature Extraction in Time Series Streaming Data

Byeong-Uk Jeon,Kyungyong Chung 한국인터넷정보학회 2022 KSII Transactions on Internet and Information Syst Vol.16 No.8

The aging society increases emergency situations of the elderly living alone and a variety of social crimes. In order to prevent them, techniques to detect emergency situations through voice are actively researched. This study proposes CutPaste-based anomaly detection model using multi-scale feature extraction in time series streaming data. In the proposed method, an audio file is converted into a spectrogram. In this way, it is possible to use an algorithm for image data, such as CNN. After that, mutli-scale feature extraction is applied. Three images drawn from Adaptive Pooling layer that has different-sized kernels are merged. In consideration of various types of anomaly, including point anomaly, contextual anomaly, and collective anomaly, the limitations of a conventional anomaly model are improved. Finally, CutPaste-based anomaly detection is conducted. Since the model is trained through self-supervised learning, it is possible to detect a diversity of emergency situations as anomaly without labeling. Therefore, the proposed model overcomes the limitations of a conventional model that classifies only labelled emergency situations. Also, the proposed model is evaluated to have better performance than a conventional anomaly detection model.
