치환된 다결정성 LiRbSO₄계의 상안정성 및 이온전도성
박성호 전주대학교 자연과학종합연구소 1997 전주대학교 자연과학연구소 학술논문집 Vol.10 No.2
The LiRbSO_4 Systems were synthesized by the different kinds of Ba doping methods. All kind of synthesized systems have many compounds which are identified as LiRbSO_4 doped with Ba, Rb_2SO_4, Li_2SO_4, etc. From this, it can be found that synthesized specimens from composites and X-ray results reveal that Li_1.0Rb_0.9(SO_4)_(1+0.05) system has orthorombic structure whose lattice parameter, ao and co are increased by the doping of Ba^2+ site. The room temperature conductivity of Li_1.0Rb_0.9(SO)_(1+0.5) was increased by one order of magnitude higher than that of pure LiRbSO_4 and this system has one resistance factor and one capacity factor which are considered as bulk properties.

Lithium Potassium Sulfate crystals have hexagonal symmetry and they belong to the space group P6_3. There is no information about ionic conductivity of Ba-doped LiKSO_4 therefore, Ba-doped LiKSO_4 systems investigated ionic conductivity and examined conduction mechanism. Stabilized systems of Ba-doped LiKSO_4 was obtained sintering time of 48 hours and sintering temperature of 600℃. The power crystal structure were investigated by the X-ray power diffractometer(XDR). XDR pattern analysis results showed that lattice parameters, a_0 and c_0 are decreased due to the substitution of Ba^2+. Ba^2+ion was substituted K^+ ion site with the consequence that lattice parameters are decreased by the ion size effect. Occurrences of the phase transition was identified by TG-DTA patterns and the morphology of the systems was examined by SEM. TG-DTA analyses, reveal that known phase transition temperature is lower. From SEM analyses, it could be confirmed that these synthesized systems consisted of hexagonal and orthorhombic structure. The ionic conductivity of these systems is investigated by frequency variable a.c. method at the temperature region of 25℃ to 600℃ under the Nitrogen gas and gold are deposited onto the specimens in order to use as an inert electrode.

사염화탄소 유발 흰쥐 경변간의 단백합성과 Alpha-Aminoisobutyric Acid의 세포내 이행에 관하여
박성호,유호열 慶北大學校 醫科大學 1973 慶北醫大誌 Vol.14 No.2
The purpose of this work was to study the change of the activity of protein synthesis and cellular transport of amino acid in rat liver induced severe cirrhosis by a long term administration of carbon tetrachloride. Sprague-Dowley rats were injected subcutancously twice weekly with a 50% solution of carbon tetrachloride in olive oil for 13 weeks. Twenty four rats developed severe cirrhosis of the liver were used for the experiment. The incorporation of amino acid mixed-^14C into liver protein decreased by 26% whereas the uptake of alpha aminoisobutyric acid-^14C in liver tissue was reduced by 60% in the cirrhotic liver compared to control rats. About fact revealed that, in the cirrhotic liver, the damage in liver protein synthesis was less significant though the cellular transport of amino anced was strikingly inhibited.

불균형한 작업시간을 갖는 제조라인의 일정계획에 대한 연구
박성호 전남도립대학교 2007 전남도립대학교 논문집 Vol.10 No.-
The purpose of this study is developing scheduling logic and program for machining scheduling for production line with unbalanced processing time. Three rules are developed to minimize slack and effect on other job. Fourth rule is suggested which considered weighted sum of three factors. schedule is generated totally 1,000 times and then optimal weight parameter is selected. The program is developed to schedule situation to compare with the performance measure, total finish time of machine and total tardiness of part. As a result, the rule which considered weighted sum of three factors is effective for both measure.

'지각된' 수업 특성이 중학생의 수학 성적 향상에 미치는 영향
박성호,김기석 한국교육개발원 2009 한국교육 Vol.36 No.1
이 연구는 그 동안 학교효과연구에서 상대적으로 소홀히 다루어졌던 교수-학습 수준에서의 수업 특성이 학생의 성적 향상에 미치는 영향을 분석한 것이다. 이를 위해 이 연구에서는 중학교 2학년 학생의 수학 성적 향상 점수를 종속 변인으로 학생들이 '지각한 ' 수학 수업의 특성을 중심으로 그 효과를 분석하였다. 이 때 수업 특성 변인은 '구조화된 수업 특성’, '촉진적 수업 특성’, '개별화, 다양화 수업 특성' 등 3개로 구분하였다. 분석 결과, 배경 변인과 학교 풍토 변인을 통제한 상태에서 수업 특성 변인 중 '구조화된 수업 특성' 변인의 효과가 유의미하게 나타났다. 이는 교사가 수업을 체계적으로 조직화하고 효율적으로 내용을 전달한다면 학생들의 학업성취 정도는 개인 및 학교의 배경과 상관없이 향상될 수 있음을 의미한다. 아울러 이러한 결과는 우리나라 입시위주 교실 수업 조건에서 학생들의 학업 향상에 영향을 미치는 수업 특성이 무엇인지를 알려주는 것이기도 하다. This study analyzes the effect of teaching characteristics that are essential to students' cognitive achievement but have been largely neglected in the research of school effectiveness. For this purpose, this study analyzes the effect of teaching characteristics 'perceived' by students on improvement in math scores for 8th grade students. The teaching characteristics were classified into three categories: 'structured teaching,' 'facilitative teaching,' and 'individualized and diversified teaching.' As a result, after controlling for the background variables and school climate variables, it was shown that 'structured teaching' had a significant effect on improvements in student achievement. This means that if teachers organize their instructions well and deliver them efficiently, student achievement could improve beyond the effects of students' and schools' backgrounds. On the other hand, the results also show what “effective” teaching characteristics are at the middle school level, under the condition that the entrance examination is highly important in high school.
