한반도의 22개 지진과, 북중국의 46개 지진자료를 활용하여 직접적으로 지진규모 평가가 어려운 우리나라 역사 지진의 규모 평가 방법을 도출코자 하였다. 한반도를 포함한 Sino-Korea craton에서 지진효과, 피해 등으로부터 구한 최대 진도($I_0$)와 지역규모($M_L$)와의 관계식은 $M_L=1.7+0.57{\times}I_0$이다. 감진면적만 추정이 가능한 역사지진의 경우, 한반도에서 적용 가능한 지역규모-감진면적(FA) 식은 $M_L=4.29-1.34{\times}log(FA)+0.28{\times}log^2(FA)$이다. 그러나 역사지진에서 감진면적에 대한 불확실성으로 인해 지진효과, 피해 기록과 감진 면적이 동시에 기록된 경우 최대진도-규모 관계식을 통해 규모를 평가하는 것이 더 타당하다고 본다.

Carbon felts were prepared under various thermal conditions to improve the electrochemical properties of vanadium redox flow batteries. The number of C-O and/or C-OH functional groups on the surface of the electrodes treated under airless conditions was much larger than that of the untreated and partially oxygen-treated electrodes. The carbon felt treated under airless conditions had the lowest surface area. The overall kinetic properties of the redox reaction were greatly improved for the carbon felt treated under airless conditions; i.e., the reversibility of the anodic and cathodic reactions associated with the $VO_2{^+}/VO^{2+}$ couple became more reversible. Single-cell tests indicated that the carbon felt exhibited an excellent discharge capacity of $3.1Ah{\cdot}g^{-1}$ at $40mA{\cdot}cm^{-2}$, and the corresponding Coulombic, voltage, and energy efficiencies were 89.5%, 91.8%, and 82.2%, respectively.

This study was to investigate the relationship of VDT(visual display terminal) work condition and fatigue severity in the financial office workers. Questionnaires were completed by 662 persons in VDT workers of Post Office from January to May 2006. Multidimensional Fatigue Scale(MFS) that was developed in Korea Occupational Safety &Health Agency to estimate the degree of fatigue was used for study. In results, 149 persons(22.5%) in VDT workers were felt low fatigue severity, 351 workers(53.0%) were middle, and 162 workers (24.5%) were high. So it was appeared that one in four VDT workers felt the high fatigue severity. And woman VDT workers felt more fatigue severity than man. Also, fatigue severity was increased with increasing work time. Our findings suggest that VDT workers in financial office need proper health program to prevent occupational fatigue and disease.

381 students including elementary school boys 75, girls 76 & middle school boys 115, girls 115 were examined to study the factors of dental esthetic self-evaluation: as measured by questionnaire & dental examination. The following results were obtained: 1. In the case of the girls, the more severely rotated or displaced the upper anterior teeth were, the uglier they felt themselves. 2. The students showed the tendency to answer that they were satisfied or had no feeling one way or the other even though their teeth were less straight than others. 3. Most of the students could not relate their teeth to the over-all facial appearance. 4. In the case of the elementary-school-boys, they felt themselves ugly when the overjet & overbite were excessive: in the case of the middle-school-girls, they felt themselves ugly when the rotation & displacement of the upper & lower anterior teeth were severe. 5. Angle's classification showed no statistical significancy.

The study explores the effects of recording and viewing distances in stereoscopic 3D on presence, perceptual characteristics, and negative experiences. Groups of 20 participants were randomly assigned to each of the three viewing distances, and all participants were exposed to five versions of the stereoscopic 3D music video that differs in recording distance. The results showed that first, viewers felt a higher experience of presence and had a better perception of objects positioned near the cameras. Second, viewers felt a greater perception of screen transmission as the viewing distance increased. Finally, viewers felt a greater negative experiences due to the joint effects of recording and viewing distance. As investigating the influence of stereoscopic 3D content and viewing environments on psychological factors, the study expects to provide a guideline of human factors in 3D.

Objective: The study aims to examine fathers' parental stress and the variables effecting parental stress of fathers with infants. Methods: One hundred seventeen fathers with 0 to 2 year-olds were recruited from daycare centers in Daejeon metropolitan city. The Korean version of the Parenting Stress Index Short Form (K-PSI-SF) by Lee, Jung, Park and Kim(2008), The Korean Occupational Stress Scale-Short Form (Koss-SF) by Jang and Ko(2005), and the Revised-Kansas Marital Satisfaction Scale(RKMSS) by Chung (2004) were used to measure fathers'parental stress, occupational stress, and marital satisfaction. Results: First, the most influential variable that affected father's parental stress was their marital satisfaction. The fathers felt less parental stress when they felt higher marital satisfaction. Second, fathers felt less parental stress when their occupational environments were family friendly. Conclusion/Implications: Ways to improve mariatal satisfacation and a family friendly evironment at work should be sought out in order to lessen the parental stress of fathers raising infants.

This paper is aimed at comparing the attitudes of parents and the psycho-sociogenic aspects of the children of Korean and Japan. The data for the analysis were derived from questionnaires administered to the 4th, 5th, and 6th-grade children in Korean and Japan. The questionnaires were designed to survey children's perception of their parents'child-rearing and the psycho-sociogenic aspects of the children's personality in Korea and Japan. The child-parent relationships identified by the children were measured by the items indicating the degree and the extent to which they felt their parents' dissatisfaction, complaints, strictness, expectation, interference, worry, indulgence, blind obedience, contradiction and disagreement. The psycho-sociogenic aspects of the children's personalities were measured by the items indicating the degree and extent of how they felt about their own sociablility, independence, aggressiveness, extent of how they felt about their own sociability, independencem aggressiveness, participation in groups. Spontaneity, self-control and public spirit.

The Purpose of this study was to compare the school life of Korean high school students between Public and proprietary schools, especially focused on their internal experiences and flow. Internal experiences were composed of three dimensions: emotion, cognitive efficiency, and satisfaction. How was classified into four conditions: apathy, boredom, anxiety, and flow. The study results are: 1. Korean high school students felt more flow when they were in public school than in proprietary school,. In public school, they felt relatively more bored, and on the other hand, they were relatively more anxious in proprietary school. 2. Korean high school students felt more positive emotions when they were in public school than in proprietary school. 3. Korean high school students were more involved into study when they were in public school than in proprietary school. 4. Korean high school students were more satisfied when they were in public school than in proprietary school.

Extensive disease surveys performed during the summers of 2013 and 2014 in Schisandra chinensis orchards resulted in the finding of a Septobasidium sp. associated with felt disease. The fungus was characterized to be symbiotic with a scale insect (Pseudaulacaspis cockerelli). Morphological and molecular characteristics of the Septobasidium isolates were investigated. The isolates were morphologically and phylogenetically close to S. bogoriense. We tentatively describe this isolate as a Septobasidium sp., mainly because of the limited amount of information available on the internal transcribed spacer region of the ribosomal DNA of Septobasidium spp.
