박종필(Jong Pil Park) 한국체육교육학회 2000 한국체육교육학회지 Vol.4 No.2

The major goal of this research is to analyze the effectiveness of the current Exclusive Physical Educator System(EPES) in elementary schools and to consider alternatives which improve the problems found in the course of actual enforcement. Results on perception for this system are analyzed from questionnaire survey made by 124 Homeroom Teachers(HT) and 132 Exclusive Physical Education Teachers(EPET) having secondary teacher`s certificate in elementary schools in Pusan. By all results of this research, most of HTs understand for EPETs` necessity in the respects that EPES can provide students for various physical experiences and reasonable management of Physical classes, and Physical subject is professional functional subject. While the EPETs have more positive understanding for current management of EYES, a great number of HTs have negative understanding for this. The reasons of negative answers by HTs are shortage of short-term teachers, HT`s avoidance for EPET, and shortage of total teachers, and the reasons by EPETs are poor physical environments, avoidance of HTs, and shortage of short-term teachers. Most of EPETs have charge of about 20 hours a week in 5th and 6th grades. A great number of EPETs have deep knowledge for the curriculum and have achieved learning goals efficiently compared with HTs. Also it is said that HTs have difficulty in textbook study and practical ability, and EPETs have difficulty in shortage of teaching materials and equipments for achievement of learning goals. It shows that HTs prefer to current system, whereas EPETs want to get elementary teacher`s certificate based on the EYES for their reasonable future course. Also EPETs answered that class responsible hour should be adjusted into 15 to 20 hours, and one teacher per four classes should be arranged in over 4th grade class. It is perceived reasonably that EPETs should be educated at Physical Education Department in National University of Education, and should be made up of current short-term teachers. Regarding with factors of efficiency reinforcement in EYES, HTs answered that allowance should be given to EPETs, and systematic matters such as education for special Physical teachers should be strengthened. In the other hands, EPETs pointed out more realistic problems for current Physical classes like teaching materials and security of facilities such as gymnasium.

박종필(Park Jong Pil) 한국교육행정학회 2006 敎育行政學硏究 Vol.24 No.2

본 연구의 목적은 여교사의 행정직 진출에 부정적인 영향을 주고 있는 불평등적 요인 및 현상을 밝히고, 이러한 결과를 토대로 하여 양성 평등 차원에서 여교사의 행정직 진출을 확대 및 현 상황을 개선할 수 있는 방안을 모색하는 것이다. 이러한 연구 목적을 달성하기 위해 각종 통계 연보를 통해 여교사의 행정직 진출 상에 불평등 현상이 존재함을 밝히고, 전·현직 교장들을 대상으로 한 면접을 통해 여성의 행정직 진출을 저해하는 원인을 고찰하였다. 본 연구에서는 그 원인을 성역할 사회화, 가정과 직장, 사회적 통념 및 유대 관계 형성 등 4가지로 제시하였으며(물론 이들은 서로 관련되어 있다), 이러한 문제를 해결하고 여교사의 행정직 진출 확대를 위해 육아 문제 해결을 위한 사회적 및 국가적 차원의 노력, 승진 관련 제도의 보완, 여교사의 의식 변화를 위한 프로그램, 및 전체적인 인식 변화가 필요함을 제시하고 있다. The purpose of the study is to examine the inequal factors which have negative influence on female teachers' promotion to building administrators, and to suggest ways to expand and improve female teachers' opportunity of promotion based on the examination on the inequal factors. For the purpose of the study, the researcher selected five female ex- and incumbent principals using intensity sampling. Also, the researcher conducted informal conversational interviews to understand particular problems and unique situation in great depth. Based on the interview data, the researcher grouped inequal factors into four categories; sex-role socialization, the burden of child-caring and domestic duties, commonly accepted ideas on gender, and the androcentric perspective in korean society. To solve these problems and to expand the promotion opportunities of female teachers, the researcher suggests that our society and government should try to solve problems on the child-caring and provide and expand child-caring services for female workers. Also, the regulation on the advancement to administrative position should be changed to consider the female teachers' conditions, and the government and district office should provide programs on reforming of consciousness for female teachers and sex-role equality for school administrators.

조기강도 개선제를 활용한 고성능 수축저감제의 성능 개선

박종필(Park, Jong-Pil),정용욱(Jung, Yong-Wook) 한국산학기술학회 2016 한국산학기술학회논문지 Vol.17 No.4

콘크리트의 내구성 저하로 인한 균열의 보수 및 보강에 소요되는 비용은 콘크리트 구조물의 유지비용 증대로 연결되 어 균열발생 저감에 대한 연구가 요구되고 있다. 특히, 전력공급용 시설인 전력구의 경우 지하 매설물이므로 보수 및 보강은 경제적으로 큰 부담이 된다. 그러므로 지하매설 전력구의 경우 효과적인 균열 저감 방안이 설계 초기단계부터 요구되어진다. 본 연구는 전력구용 저수축 콘크리트 제조를 위한 수축저감제 개발의 일환으로 수축저감제 사용 콘크리트의 초기 강도 개선 을 위해 TEA를 검토하였다. 검토결과, TEA를 수축저감제의 3% 사용할 경우 조기 강도가 크게 개선되었으며, 수축저감 효과 도 우수한 것으로 확인되었다. 또한, TEA 3 %에 수축저감제 2.0 % 혼합하여 적용하였을 경우 압축강도 특성 및 건조수축 길이변화 실험결과에서 가장 우수한 것으로 나타나 수축저감제로서의 가능성을 확인하였다. 추후 수축저감제의 범용적인 적용성 검토를 위하여 수축저감제의 사용재료 변화 등에 대한 다양한 재료변수 요인 검토를 통하여 수축저감제의 성능 검토 가 필요할 것으로 사료된다. Studies aimed at reducing the occurrence of cracks by the shrinkage of concrete are in demand because the repair and reinforcement for cracks caused by declining concrete durability costs the user to maintain the concrete structure. In particular, in underground power facilities for power transmission, the cost is a heavy burden to repair and reinforce. For this reason, underground power facilities demanded effective methods for crack reduction at the engineering design step. This study, as a part of the development of shrinkage reducing agent for low shrinkage concrete on underground power facilities, investigated TEA to complement the shrinkage reducing agent to improve the early strength of concrete. In the case of TEA 3% as a shrinkage reducing agent, the early strength was improved significantly, and the shrinkage reducing effect was excellent. In addition, TEA 3.0 % and the shrinkage reducing agent 2.0 % showed excellent shrinkage property and compressive strength. On the other hand, more study of shrinkage reducing materials, including performance reviews on the shrinkage reducing materials with variable factors and type of materials, will be needed to generalize these results.

Second, Korean elementary schools try to pr ovide informations not only on the result but also the proces s of students’ acti vities to parents by On-line st udent report cards. Finally, to provi de more c orrect informatio ns on their children and to h elp parents to unders tand info rmations at the rep ort card, Korean elementary sc hools need to ado pt the standard-ba sed report card syst em.

API 공정의 본질안전설계를 통한 위험성저감 및 비용·편익 분석에 관한 연구

박종필(Jong-Pil Park),천영우(Young-Woo Chon),이익모(Ik-Mo Lee),김홍관(Hong-Kwan Kim),황용우(Yong-Woo Hwang) 한국위험물학회 2021 한국위험물학회지 Vol.9 No.2

This study performed HAZOP, which is a qualitative risk assessment for the API(Active Pharmaceutical Ingredient) process, and aimed to check the solvent change, the root cause, to reduce the derived risk, select accident scenarios and high-risk solvent materials, and identify the substitution of low-risk solvent substances. This study conducted the Consequence Analysis(CA), which is a quantitative risk assessment, to determine the extent of damage in the event of a chemical accident caused by solvents. In addition, the ALOHA of the US Environmental Protection Agency was utilized, and the estimated impact scope was quantified as the cost of disaster loss, in addition to performing a cost-benefit analysis that considers safety and economic feasibility. The difference in the impact scope in the toxic exposure was relatively larger than the difference in the impact in the impact scope in the liquid fire of methanol and ethanol. Due to the characteristics of the pharmaceutical industry, it can be fatal to the human body if methanol remains in pharmaceuticals. Accordingly, it is recommended to use ethanol instead of methanol. This study examined solvent change and suggested a cost-benefit analysis that considers safety and economic feasibility. As a study on the intrinsic safety that replaces high-risk solvents with low-risk solvents, it is expected to contribute to the prevention of serious industrial accident caused by chemicals.
