본 논문은 전산센터에서 발생하는 비화재보를 분석하여 전산센터에 미치는 장애요소를 개선하고자 한 것이다. 전산센터의 중요성에 의해 설치된 감지기의 감도는 모두 예민하게 되어 있어 비화재보 발생이 많았으며 노이즈발생, 미세먼지, 항온항습기의 바람, 온도 등이 비화재보의 주원인 이었으나 이외에 11가지가 발생되었다. 이들 비화재보는 소화약제 방출에 따른 충전비용 발생, 시스템 정치에 따른 전 시스템이나 시설의 정지등으로 파급되어 생산성 저하, 신뢰성 저하등을 초래하는 것으로 나타났다.

항공산업은 그 특성상 고도의 신뢰성, 안정성이 요구되며, 이를 충족시키기 위하여는 복잡하고 정밀한 구조를 가져야 하므로 다른 산업제품과는 비교가 안될 정도로 그부가가치를 가지고, 타 산업에의 기술 파급 효과가 역시 지대하다. 따라서, 우리나라와 같이 부존자원이 빈약하나 인적 자원이 우수하고 풍부한 나라에서는 자원절약형 산업인 항공산업의 타당성을 검토, 장기적인 육성방안을 수립하여 추진하는 것은 시대적인 요구라 할 수 있다. 이러한 요구에 따라 국방과학연구소에서 공군의 초, 중등훈련기 개발을 추진 중에 있음은 KFP(Korea Fighter Program)사업과 함께 매우 중요한 의미을 갖는다. 이와 같은 시점에서 한국인의 인체특성에 보다 적합한 항공기의 개발은 가장 시급한 과제이며, 이 문제점을 극복하기 위한 기본연구로 조종실 내부설계에 필요한 기준점 및 치수, MIL-SPEC에서 규정하고 있는 기준치를 분석하였으며 실제 항공기(F-5, F-4, F-16)칫수를 측정하여 이를 정면도, 측면도, 평면도로 제시하고, 항공기 제어계통인 조종간, 동력제어기, 러더페달 및 조종석의 실제 측정치와 공군 조종사의 인체측정치를 비교, 평가하였다. 또한 전투기들의 정면 계기판과 좌, 우측의 제어판의 표시장치 및 조작기들을 기능별로 구분하여 각 요소별 제한조건 및 설계지침들을 비교, 분석하였다.

This article examines the role and influence of educational achievement on Korean society and its future. Four major factors that associated with and influence educational achievement in Korea (i.e., trust, efficacy beliefs, quality of life, and societal transformation) are reviewed. First, the role of educational achievement on establishing a basis for trust in Korean society is examined. By reviewing studies of perception of Korean society, people and institutions, the importance of establishing trust in Korean society is outlined. Second, the role of efficacy belief in promoting educational achievement is examined. The importance of collective efficacy, at the adolescent, adult and political levels is emphasized. In addition, the concept and application of self-efficacy for teachers and parents is reviewed. Third, the role and influence of educational achievement on quality of life is outlined. Studies indicate that educational achievement plays an important role in improving the quality of life. The pressure to achieve, however, can have negative impact on stress and mental health and support systems need to be developed to alleviate their impact. Fourth, the future and prospects for Korean society through educational achievement is discussed. Through education, the importance of bridging the divide with North Korea is an important agenda for the future of Korean society. Finally, the importance of indigenous psychological perspective in understanding Korean society and providing direction for the future is discussed.

Gyeongbu and Namhae expressways in the country, are the major arterial highways which are connected with the Busan port in the north-south and east-west directions, respectively, and required to study the traffic characteristics about the hourly volume factors(K-factor) by concentrated midium-size and large-size cargo trucks of 20% or higher in expressways. We therefore attempted to predict the K-factor in expressways through the correlation analysis between K-factor and K-factor estimates on the basis of the short-term VDS data collected at the basic segments of the above major expressways. As a result, power model appeared to be appropriate in predicting K-factor by the K-factor estimate based on VDS data for 7 days with a high explanatory power and validity.

The purpose of study was to measure the interrater reliability of the newly developed caries diagnostic instrument, Diagnodent(KaVo, Germany), using a new laser fluorescence techinique. One hundred and three extracted human premolars and molars were examined by Diagnodent, three times for fissures and five times for smooth surfaces. There was no significant difference among the three fissure means, but two combinations showed significant differences among the five smooth surface means. Correlation coefficients of Pearson and Spearman were all above 0.9(P<0.01). The $\alpha$ values from reliability analysis were 0.9980 or 0.9981 for fissures and 0.9992 for smooth surfaces.

There will be coming soon a sequence of the so-called election season in Korea. That is the 20th session of general elections and the 19th presidential election which are taking place one after another. When we talk about presidential candidate, we may realize that the choice were relied upon candidate's facial appearance and speech, voice, dress, and so on. One poll showed that capacity and policy were ranked high and figure and image were ranked next by asking "what is the most important factor when you vote for the president?" This study looked into the candidate's face of a newly elected public office through the election voting. I studied how the factors of sex and beauty may affect on the election results. I analyse survey of candidate's photo on the election leaflets. Analyzed result said that candidate's competency and trust have strong relations in the voting choice rather than beauty even if it is statistically significant. I also find that both beauty and competency are positively interrelated.

While SNS services such as Twitter or Facebook are rapidly growing, research for the SNS analysis has been concerned. Especially, twitter reacts to social issues in real-time so that it is used to get useful experimental data for researchers of social science or information retrieval. However, it is still lack of research on the methodology to collect data. Therefore, this paper suggests the tweet acquisition system by considering tendency of twitter user oriented location-based event and political social event. First the system acquires tweets including information of location and keyword about event and secure IDs for acquisition of political social event. Then we plan ID-analyzer to classify the tendency of users. In addition for measuring reliability of ID-analyzer, it acquires and analyzes the tweet by using high-ranked ID. In analyses result, top-ranked ID shows 88.8% reliability, 2nd-ranked ID shows 76.05% and ID-analyzer shows 77.5%, it shortens collection time by using minority ID.

The purpose of this study is to identify the relationship between people's ideological orientation and the populist attitude in terms of demand of populism. The influence of subjective ideology evaluation and political party support on anti-elitism (AE), people centrism (PC) and anti-pluralism (AP) are analyzed in detail. To research this, the socioeconomic factors, democracy recognition and the method of political participation are set as control variables, and the ideologies are classified into extreme conservative, conservative, moderate, progress, and extreme progress. The data are collected through nationwide online survey. The results of the analysis are as follows: First, the powerful affinity between ideological orientation and populist attitude are confirmed. The support for conservative ideology (especially extreme conservative) and the conservative party are affecting the AE and AP, and the ideology of extreme progress and support for the progressive party are influencing the PC and AP. When putting together 3 types of attitude, the conservative (especially extreme conservative) and extreme progressive ideology are the factors that determine the populism attitude. Second, There was no impact of socioeconomic variables except gender (female) and age. Third, populist attitude have a multidimensional nature determined by democratic satisfaction, government trust, external efficacy, voting and non-voting activities.

This study investigates Koreans respondents' perception of American society, American people and its influence in Korea and the world. These analyses have been conducted to provide the psychological, social and cultural basis for understanding the anti-American sentiments among Korean junior high school students, university students and adults. American influence is further divided into American influence on Korean society, on North-South Korean unification, and in the world. In addition, respondents' knowledge of the USA, their satisfaction with the current political functioning, and background information were obtained. A total of 763 respondents (171 junior high school students, 250 university students, and 342 parents of junior high school students) completed a survey questionnaire developed by the first two authors. The overall results indicate that the respondents had a negative view of the USA and its influence in Korea and the world. Majority of respondents perceive American society as being commercial, exclusionary, and ethnocentric. Some respondents perceive American society as being democratic and advanced. As for American people, they are perceive them as being selfish and at the same time independent and carefree. The trust for American society is very low. As for American influence in Korea, it is perceived it as creating dependency and less likely to be perceived as promoting progress and development. As for North-South Korean relations, respondents perceive the USA as interfering with the unification of two Koreas. Finally, respondents perceive the USA as a superpower with imperialistic and dominating tendencies and they were less like to perceive the USA as promoting democracy and justice. Significant differences across the age groups have been found with the junior high school students holding the most negative view about the USA and their parents holding the most positive view of the USA. University students had mixed views of the USA. holding both positive and negative views of the USA. Those respondents with greater dissatisfaction of the political system and with less knowledge about the USA has more negative views of the USA.
