Purpose: The purpose of the study was to evaluate the status of safety accidents and importance-performance analysis (IPA) between regular and non-regular employees in industry foodservices. Methods: The participants were regular employees (n = 119) and non-regular employees (n = 163) in industry foodservices in the Jeonbuk area. Demographic characteristics, status of safety accidents, safety education, and importance and performance status were assessed using a self-administered questionnaire. Results: Approximately 66.4% of regular employees and 53.4% of non-regular employees experienced safety accidents (p < 0.05). Types of safety accidents of regular and non-regular employees were mostly burns, and causes were mostly from their own negligence. Approximately 98.3% of regular employees and 95.1% of non-regular employees experienced safety education. Approximately 88.9% of regular employees and 96.8% of non-regular employees received safety education from dietitians. Approximately 41.9% of regular employees and 50.0% of non-regular employees had difficulty applying the contents of safety education due to lack of time during work. As a result of IPA, regular and non-regular employees were aware of the importance of the following and performed them well: 'Clean the floor of the work place', 'Arrange in the work area', 'Wear safety shoes', 'Check for heater cord', and 'Safety cooking when using oil'. On the other hand, they were not aware of the importance of the following and performed them insufficiently: 'Check for the MSDS', 'Aware of chemical signs', 'Wear protection gloves etc.', 'Do stretching exercise', and 'Using ancillary tools'. Conclusion: Therefore, it is necessary to improve the consciousness of dietitians for effective application of safety education contents, development of contents, especially MSDS, and related things.

우리나라 복식산업의 전문인력 양식은 주로 대학교나 전문학원에서 이루어지고 있으며 수적인면에서는 충분한 인력이 양성되고 있다. 그러나 질적인 면에서 산업체에서 요구되는 역량을 가진 전문인은 부족한 편이다. 이에 따라 산업체의 요구에 부합하는 인력야성을위하여 교육과정의 개선이 절실히 요구되고 있다. 따라서 본 연구에서는 실기교육 산학협력 및 산업체 현장실습이 활발히 이루어지고 있는 영국의 복식관련학과에 대하여 조사해 봄으로써 우리 교육의 개선방향을 모색하고자 한다. 영구의 경우 다양한 자격증 및 학위과정이 개설되어있으나 본 연구에서는 우리나라 학사학위에 해당되는 BA 및 Bsc만대상으로 하였으며 설문조사 문헌조사 및 사례연구를 통하여 현황 및 교과과정을 분석하였다 영국의 복식관련학과들은 그 교과과정 및 내용에 따라 크게 6개 전공분야로 분류되었으며 각 하과는 다시 세분화되어 전문성이 있는 교육이 이루어지고 있었다 또한 수업연한 및 과정의 형태에 따라 5개 유형으로 분류되었다, 이유형 중 특히 일년간의 현장실습을 학위과정으로 포함시켜 의무적으로 산업체에 근무하도록 되어있는 Sandwic Mode는 적극적인 산학협력의 한 형태로 매우 효율적으로 평가되는 교육체계이며 여러다른 학문 분야에서도 널리 활용되고 있는 체계이다. 교수진의 경우 전임교원이 수적인 면에서 다소 부족한 것으로 나타났으나 관련 산업체 인사 등을 시간강사로 고용함으로써 이를 보완 할 뿐 아니라 산학연계를 이루고 있었다. 또한 전임교원의 경우 주로 학사 혹은 석사의 학력을 가지고있었다. 그러나 모든 전임교수 뿐 아니라 시간강사의 경우도 산업체 경력을 필수 적으로 가지고있어 고학력위주의 우리나라 실정과는 매우 상이했다. 교과과정에 대한 사례연구에서 직물디자인에 집중된 2개 과의 교과과정을 보았으며 그중 한 개 과는 다시 편물 프린트 및 직물 디자인의 3분야로 세분화되어 심도 있는 교육이 이루어질 수 있는 것을 살펴보았다 또한 다른 3개의 예에서 볼수있듯이 2개 이상의 전공코스를 도입하여 공통과목과 전공 코스 과목을 둠으로써 시설 및 인적 자원의 활용 등 운영상 효율성을 추구함을 알수 있었다 또한 학생들의 경우 전문화된 코스의 선택을 할수 있게 하였다 이런 실례는 전문인력양성이 매우 필요하고 따라서 전공코스제의 도입의 필요성이 대두되고 있는 이시점에서 매우 유용하게 이용될수 있으리라고 생각된다. 영구의 교육이 우리나라 실정에 그대로 적용될 수는 없지만 본 연구 결과를 바탕으로 다음과 같은 시사점을 고려하여 우리교육을 개선해 나갈 수 있으리라고 생각한다. 첫째 교수진 인적 물적상황 및 지역적 상황등을 분석하여 각 대학별로 그 특성에 맞는 세분화되고 심도있는 전공교육과정을 개발 발전시켜 야 할 것이다 둘째 산업체 방문 산업체인사와의 면담 및 특강 등 산학협력을 좀더 적극적으로 모색하여야 할 것이다. 셋째 학생들의 산업체 현장 연수를 실질적으로 도입하여 산업체의 인력요구에 적극적으로 대처 할수 있어야 하겠다.

PC-type copolymers were synthesized using MPEG(polyethylene glycol methyl ether methacrylate, Mn=2080) to different mole ratios of mono-carboxylic acid(AA : acylic acid). The mole ratios of AA were 2, 3, 4 and PC-type terpolymers were synthesized using mono-, dicarboxylic acid(ITA : itaconic acid MAL : maleic acid) with the same graft chain. To investigate effects of PC-type co-, ter-polymers on the hydration of cement experiments involving FT-IR, XRD, DSC, SEM have been analysed with cement paste specimens to 1, 3, 28 day. The hydration reaction rate of cement paste was slightly delayed at 1 day, due to increase in molar ratio of [AA]/[MPEG], it was recovered in the days after and the copolymer was more active than the terpolymer, because of low carboxylic acid content PC-type copolymers applied 2AA-type were fastest copolymer on hydration reaction of cement paste to 3 day and the more AA mole ratios increased, the more hydration was retarded.

In this study 2 cadalene homologues - 3,7-dimethoxycadalene and 7-hydroxycadalene-5,8-quinone (keyakinone A)-were further identified from ethanol extracts of Zelkova serrata wood, except 7-hydroxy-3-methoxycadalene. Two biological activities-scavenging activity of hydroxy radical and cell toxicity by MTT assay-were measured with 7-hydroxy-3-methoxycadalene. The scavenging activity of hydroxyl radical of the compound was excellent and increased with its concentration. At 100 ppm hydroxyl radicals were removed completely. However, MTT assay revealed that 7-hydroxy-3-methoxycadalene showed critical toxicity to the cells. When 1 ppm of the compound was treated to the cells, cell viability was reached up to 90%, while it was reduced to 22% after treatment of 9 ppm. In 4 different Ulmaceae species, such as Ulmus davidiana, Ulmus parvifolia, Ulmus macrocarpa, Ulmus macrophylla, 7-hydroxy-3-methoxycadalene was not found at all. Instead, 7-hydroxycadalene (Mw 214), in which methoxyl group is omitted from 7-hydroxy-3-methoxycadalene, was distributed in the heartwood of 4 Ulmaceae species as major cadalene compound.

This study was progessed from March 3, 2015 to March 31 for purpose of evaluating the effects of the trauma-patient practice education using simulation on knowledge, satisfaction and problem-solving in paramedic students. To closely examine the adequacy of education for paramedic students in one university, a comparison was made by dividing 28 male and female students into two groups of experimental group with 14 students and control group with 14 students. The experimental group was carried out the practice education of the trauma-patient simulation using simulator. The control group was conducted the theoretical and practical education through a traditional instructor-led class. As a result of the research, the experimental group can be known to be significantly higher(t=2.09, p<.05) than the control group in the post-knowledge survey and satisfaction following the development in each educational method for 4 weeks. Also, in consequence of the variable-based correlation in the sub-factors of satisfaction, a correlation was shown between interest and clinical help or between interest and problem-solving ability(p<.05, p<.01). Based on the results of this study, it is considered that the simulation practice education in the emergency department is demanded and that the practice education will need to be continuously applied through developing a proper scenario.

Let me introduce a teaching method to improve practice capacity in dental laboratary work. I applied theories of layers of modeling and reflection constituting cognitive apprenticeship and peer tutoring to my class. At internet uploading a file showing a practice procedure a week before the class of a course, I let students preview it. During the class I demonstrated the practice procedure in front of students. A superior student and an inferior student paired according to the previous practice grade and a feedback between a peer tutor and a peer tutee was activated. Late in the class, a student self-evaluated his own practice result and had a check of a professor. Finally he compared his own practice result with that in the file uploaded at internet and reflected. This teaching method led to improvement in students' satisfaction and efficiency of learning.

There is true that the evaluation of non-face-to-face swimming classes currently offered by universities due to the COVID-19 outbreak is generally negative. For this reason, the quality of non-face-to-face swimming classes at universities is bound to depend on the expertise of the instructor. However, whether or not of students who lack of practices of swimming could experience exercise flow and could continuously last the swimming exercise after semester or even graduation is difficult to confirm. This is considered to be a significant threat in the future not only for swimming, but also for all liberal arts and lifestyle sports. This study aimed at 281 non-athletic college students with experience of taking both swimming classes, and the need for a study on the structural relationship between exercise flow and participation intention by university swimming class leaders' expertise in non-sports majoring college students. And the results were empirically analyzed. The research results derived in this process are summarized as follows. First, the effect of swimming class leader's expertise (personality, lecture skills, student management, practical skills, basic knowledge) perceived by non-athletic college students on exercise flow (cognitive flow, behavior flow) affects cognitive flow. As a factor influencing, it was found that lecture skills had a statistically positive (+) effect, and as factors influencing behavioral commitment, the positive (+) effect was statistically significant in personality, lecture skills, student management, and basic knowledge. Second, as for the effect of exercise commitment (cognitive commitment, behavior commitment) perceived by non-athletic college students on continuous participation intention, the behavioral commitment factor was found to have a statistically positive (+) effect.

The study aims to explore the rapidly changing university sports-related lecture environment from the perspective of professors and seek comprehensive and practical improvements in the online lecture environment for both professors and learners. In order to achieve the purpose of this study, six professors related to physical education at the university were selected as research participants, and in-depth interviews were used for about four months from September 2020 to December 2020. Examples of the problems, counterplans, and the improvement plans of professors who related to sports were shown as the results. First, the difficulties faced by professors have been divided into online and offline lecture problems, which are Internet and media possession, online lecture place amulet, professor-learner communication disorder, attendance verification and evaluation, COVID-19 infection, and face-to-face lecture place restriction since the outbreak of COVID-19. Second, professors' response to online and offline lecture problems was diversification of communication media, telecommuting, providing online learning videos, replacing and reinforcing practical classes, which were found to be somewhat lacking in government and school support systems. Finally, since the COVID-19 outbreak, Sports-related lecture's continuous problems and the professor's responses require the improvements such as government-level guidelines, university-level expansion of the venues for on- and off-line lecture, devising online lecture programs that enhance professor's convenience, and adjusting the number of participants for on- and off-line lecture.
