Military exercises in the Joseon period can be largely divided into three: exercise conducted on land, one conducted on holy grounds and one conducted in the water. Here, a military exercise means to control the troops and inspect them in training grounds. And Sujo (military exercise of the naval forces) can be said as a military exercise of the naval forces. To date, not small amount of research on the naval forces has been carried out and yet there is indeed a lack of direct research on Sujo. Sujo in the former part of Joseon emerged, while the Joseon government maintained and strengthened the naval system to cope with the invasion of Japanese raiders. And yet, it was not made in a systemic way. Then the naval system underwent a great change by the government"s "reinforcement of awareness on the ocean defence" and accommodation of the Ming period"s books on military strategy like the Jixiao Xinshu, following Japanese Invasion of Korea in 1592. The 17th Century, in particular, was at the center of such a change and Sujo followed in the footsteps of such a revolutionary flow. Unlike in the former part of Joseon, the situations of Sujo during this period can be grasped relatively in details through Bibyeonsadeungnok, Sujoholgi and diverse books on military strategy. While study on Sujo - sort of research on unexplored area - must accompany much difficulty, this study believes such research on Sujo is likely to draw a diverse range of unheard-of research subjects related with marine humanities and history of the naval forces in the Joseon period. For this, it"s important to examine how such contents originated and how they were specified. This study believes that after going through such a process in due course, researchers are quite able to supplement the existing research and draw new subjects at the same time.

3 mol% yttria-doped stabilized zirconia (3YSZ) is synthesized by a solvothermal process, and its characteristics are investigated using various methods. Also, the dispersibility of synthesized 3YSZ nanoparticles is observed with the species of surface modifier. The 3YSZ nano sol prepared with an optimum condition is employed in prism coating and its properties are evaluated. The synthesized 3YSZ nanoparticles show a globular shape with about 10 to 20 nm crystallite size. The mixed phases with the nano sol show a high specific surface of 178 m2/g. The prism sheet coated with the 3YSZ nano sol present an excellent refractive index, transmittance, and luminance; refractive index is 1.603, transmittance is 90.2 %, and luminance of coating film is improved by 5.9 % compared to that of the film without 3YSZ nano sol. It is verified that the surface modified 3YSZ is suitable as the prism sheet for optical displays.

박정주 대한경영정보학회 2012 경영과 정보연구 Vol.31 No.1

본 논문은 2001년부터 2010년의 표본기간 동안 상장된 제조업을 대상으로 Shyam-Sunder and Myers(1999) 그리고 Frank and Goyal(2003)의 목표조정모델과 자본조달순위모델에 기초하여 Chirinko and Singha(2000)의 비판적인 관점이 반영 된 실증분석 논문이다. Shyam-Sunder and Myers(1999)의 모형을 통해 분석한 결과, 목표 조정계수는 0 과 1 사이에 값을 가지며 설명력이 높고 유의한 변수인 반면에 자금 부족분 계수는 0에 가까워 자본조달이론을 지지 하기에는 작은 값을 가졌다. 또한 Frank and Goyal(2003)의 방법론을 사용하여 실증분석한 결과 자본조달순위이론은 지지되지 않았다.

박정주 한국직업교육학회 2010 職業 敎育 硏究 Vol.29 No.4

The purpose of this study was to examine the structural relationship among collective teacher efficacy, self-teacher efficacy, and teacher commitment. It was also intended to investigate whether collective teacher efficacy had any firsthand impact on teacher commitment and whether the former exercised any secondhand influence on the latter through self-teacher efficacy. This study is ultimately meant to determine the effects of collective teacher efficacy. The correlation between collective teacher efficacy and self-teacher efficacy and teacher commitment was investigated, and the goodness of fit of the research model used in this study was verified as well. And path coefficients were calculated to determine the relationship of the three elements. As a result, it's found that collective teacher efficacy exerted an influence on self-teacher efficacy and organizational commitment, and that collective teacher efficacy affected teacher commitment through the positive mediating variable of self-teacher efficacy. And the influence of collective teacher efficacy is larger than that of self-teacher efficacy. 본 연구는 집단적 교사효능감, 개인적 교사효능감 및 교사몰입 간의 관계를 살펴봄으로써 집단적 교사효능감과 교사몰입의 관계에 있어 개인적 교사효능감이 가지는 효과를 분석하고자 하였다. 이를 위해 집단적 교사효능감, 개인적 교사효능감 및 교사몰입 간의 상관관계 분석 및 연구모형에 대한 확인적 요인분석을 수행하였고, 구조방정식 모형 분석을 통해 세 잠재변수 간의 관계를 경로계수를 통해 비교하여 보았다. 연구 결과, 집단적 교사효능감과 개인적 교사효능감은 모두 교사몰입에 정적 영향을 미치고 있으며, 개인적 교사효능감은 집단적 교사효능감이 교사몰입에 미치는 영향에 정적인 부분 매개역할을 하고 있는 것으로 밝혀졌다. 또한 교사몰입에 대한 집단적 교사효능감의 영향력은 개인적 교사효능감의 영향력보다 큰 것으로 나타났으며 집단적 교사효능감은 개인적 교사효능감에 정적인 영향력을 가지고 있었다. 따라서 학교 조직 전체의 능력에 대한 자신감을 강조하고 협동적 학교 풍토를 통해 그러한 자신감이 교사 개개인에게 스며들도록 함으로써 교사 몰입을 높이고 이를 통해 교육 변화를 이끌어내야 한다.

The purpose of this study was to evaluate the effects of toothpaste containing hydroxyapatite for patients who complained dental hypersensitivity. Before baseline of application of toothpaste with hydroxyapatite, tooth brushing instruction was done respectively and the several indices were measured at baseline, 2, 4, 8 weeks. Clinical indices were estimated, and responses to cold, compressive air, tactile stimulus were evaluated with verbal rating score. Relief effects and visual analogue scale were also evaluated. The results of this study were as follows 1. The occurrence rate of hypersensitivity in upper jaw was higher than that of lower jaws, and molar area showed more hypersensitivity than premolar and incisor area. Buccal site was hypersensitive followed by interproximal and lingual site. 2. Plaque index, gingival index and probing depth reduction were gradually improved after Tooth Brushing Instruction and using toothpaste. 3. Subjects showed most sensitive response to cold stimuli than compressive air and tactile stimuli. 4. The relief effect was increased during using tooth paste and complete relief was increased especially at 8 weeks. 5. Visual analogue scale was increased. In conclusion, it was confirmed that toothpaste containing microcrystalline hydroxyapatite have the relief effect of tooth hypersensitivity. During 8 weeks, stimulus responses were decreased and hypersensitivity relief effect was increased.

잠재성장 모형을 이용한 대학생의 직업정보인지도에 관한 종단 분석

박정주 한국직업교육학회 2010 職業 敎育 硏究 Vol.29 No.2

The purpose of this study is to analyze the trajectory of career information recognition of university students and the difference among individuals. To achieve the purpose, the data related to university students from the second to fifth of KEEP (Korea Education and Employment Panel) was analyzed by Latent Growth Model(LGM). The results are reported as follows. First, the change of career information recognition was increasing linear function. The intercept of average was 3.354 and the slope of average was .138. This means that university students had information of career 3.354 units in the first year and developed a increasing of .138 per year. And between 2nd year and 3rd year was the most increasing year. The 79.3% of career information recognition was reached in 3rd year. Second, the correlation of intercept and slope was negative. More specifically speaking, the more cognize information of career in the first year, the less change rate later on. But it wasn't significant statistically. Third, there was difference among individuals in the trajectory of career information recognition. Gender were important factor in difference among individuals. Female students had faster speed than male, and male students had more career information in the first year than female students. 본 연구는 대학생들의 직업정보인지도에 대한 종단적 변화 추이와 그에 대한 개인차를 알아보기 위해 잠재 성장모형을 이용하여 종단 분석을 하였다. 이를 위해 2차년도(2006년도)부터 5차년도(2008년도)까지의 한국교육고용패널 자료 중 대학생 자료를 사용하여 분석을 실행하였다. 주요한 연구 결과를 중심으로 정리하면, 첫째 전체 대학생의 직업정보인지도 평균 초기치는 3.354였으며 평균 변화율 .138씩 증가하는 선형 변화를 보이고 있었다. 또한, 2-3차년도 사이에 가장 많은 증가가 이루어지고 전체 증가의 79.3%가 3차년도 내에 이루어졌다. 둘째, 직업정보인지도에 대한 초기치와 변화율의 상관계수는 부적으로 나타나 직업정보인지도에 대한 초기치가 낮은 학생일수록 학년이 올라감에 따라 증가율의 속도가 빨랐음을 추론할 수 있으나 통계적으로 유의하지는 않았다. 셋째, 직업정보인지도에 대한 개인차는 초기치와 변화율 모두에서 유의한 것으로 나타났고, 개인차 예측 변수로 투입한 성별에 따라 유의한 차이를 나타냈다. 성별은 초기치와 변화율에서 모두 유의했는데, 남학생은 여학생에 비해 직업정보인지도 초기치가 높았고 여학생은 남학생에 비해 직업정보인지도 증가율 속도가 빨랐다.
