To meet the objectives of environmental education, teachers especially have to perceive the importance of environmental education, comprehend various characteristics of teaching/learning methods, and be able to conduct classes by choosing proper teaching/leaming methods in accordance with a specific purpose and educational focus about environmental education. Therefore, it Bs necessary to investigate the current status of Korean environmental education and provide teachers with appropriate environmental teaching/leaming methods. To this end this study aims to examine Korean science teachers'perceptions'on environmental education and the kind of teaching/learning methods which can be utilized in environmental education. Teachers who completed the survey were 135 science teachers from middle and high schools in Seoul, and 126 social science teachers from Kyoungki province. The majors of the science teachers were in physics, chemistry, biology, geology, and earth science. Also, there was one teacher who majored in special education. For social science teachers two majors were common, geography and general sociology. After analysis of the data from the surveys the results are as follows. First, science and social science teachers in middle and high school recognized the necessity of environmental education in school education. Second, most teachers had applied environment related topics to their subject of study occasionally, but they mostly concurred that environment related contents should be included in their textbooks. Third, science teachers agreed that field trip, discussion, and the STS approach were the most proper methods for environmental education, and social science teachers agreed that field trips, inquiry, and discussion were the most appropriate methods for a teaching environment. They realized that they should decide good teaching-learning methods appropriate to the objectives and content needed for effective environmental education as they selected different teaching-learning methods according to detailed environmental objectives and contents in their textbooks.

본 연구에서는 초등학교 교사를 대상으로 과학관의 교수-학습에 활용 현황 및 교육 프로그램에 대한 요구를 조사하였다. 연구 결과, 지금까지 과학관은 학교 교육과 밀접한 관계를 가지고 운영되지 못하였으며, 주로 일회적이거나 개인적인 활동으로 과학관 경험이 끝나는 경우가 많았음을 알 수 있었다. 또한 과학관이 교수-학습에 많이 이용되지 못하는 것은 그 교육적 효과가 미미해서보다는 외부의 물적 행정적 지원의 부족으로 인함을 알 수 있었다. 교사들이 선호하는 과학관 교육 프로그램은 캠프나 실험 등의 학생 위탁 프로그램과 학교 교육과 정과 관련된 전시물이었으며, 교사들에게 과학관과 관련된 다양한 활동에 참여하기를 물어본 결과 설문 대상의 약 80%의 교사가 과학관 학생 위탁 프로그램 개발, 과학관 투어, 캠프, 실험 등의 과학관 위탁 프로그램 운영 담당, 과학관 중심 교사 커뮤니티에의 참여, 과학관 방문 전후 프로그램 개발 등에 참여를 희망하였다.

This study discusses challenges of running expandable profile liners (EPLs) to isolate trouble zones in directional section of a deep well, and summary the expandable profile liner technology (EPLT) field trial experience. Technically, the trial result reveals that it is feasible to apply the EPLT solving lost-circulation control problem and wellbore instability in the deep directional section. Propose schemes for optimizing the EPLT operation procedure to break through the existing bottleneck of EPLT in the deep directional section. Better-performing transition joints are developed to improve EPL string reliability in high borehole curvature section. High-performing and reliable expanders reduce the number of trips, offer excellent mechanical shaping efficiency, simplify the EPLT operation procedure. Application of the expansion and repair integrated tool could minimize the risk of insufficient expansion and increase the operational length of the EPL string. The new welding process and integrated automatic welding equipment improve the welding quality and EPL string structural integrity. These optimization schemes and recent new advancements in EPLT can bring significant economic benefits and promote the application of EPLT to meet future challenges.

본 연구는 대학생들이 해외 답사여행을 수행함에 있어 소집단 사회연결망이 어떻게 존재하고 여행기간동안에 어떻게 변화하는지 그리고 여행의 제반 성과인 답사여행 만족, 학과몰입, 교우관계 등과 어떠한 관련이 있는지를 알아보는데 목적이 있다. 한국 대학생들은 유래 없는 학교적응 문제를 겪고 있는데 이러한 현상은 대학교육이 제대로 이루어지고 있는지에 대한 의구심과 이에 대한 해결 필요성을 증대시켜주고 있다. 여행은 참가자 집단에게 강한 유대감을 제공해주기 때문에 같은 맥락으로 학생들의 해외답사여행이 학생집단 결속을 강화시킬 수 있다는 가정을 해 볼 수 있다. 해외답사여행에 참여한 31명의 대학생을 대상으로 설문조사를 실시하여 유의미한 소집단 연결망 구조의 존재 여부, 그 변화양상 그리고 관련 변수간의 영향 등을 알아보았다. 첫째로, 대학생 해외답사여행의 소집단 연결망 구조는 학생 집행부 소속 학생들이 연결 중심성의 위치에 있는 등 비교적 명시적으로 존재하고 있었다. 둘째로 출발 전과 출발 후에 연결망 구조가 변하였으며 이는 여행기간 중에 참가자간의 상호작용이 발생한 것에 기인한다. 셋째로, 소집단 연결망 구조 변화에 따라 연결중심 및 매개중심으로 이동하였다 하더라도 제반 여행성과 변수에 주는 영향은 제한적이었다. 넷째로 답사여행 만족, 학과몰입, 교우관계는 유의한 상관관계를 가지고 있었다. 논문 말미에 연구 시사점과 한계점을 포함하였다.

The purpose of this study is to survey the instructional state of the unit 'Small Living Things' in the Elementary School Science. for this study, 100 teachers were surveyed on teaching-learning practices. More specifically, questions were asked on the degree of accomplishing instruction objectives, frequency of field . study, experimental preparation, alternative instructional methods, amount of preparation, availability of reference books for teachers and availability of information materials on the Kwangju region. Our results show that teachers find the objectives related to the collection of living things for class experiments and the task of growing and observing them the most difficult to accomplish. It was reported that 38% of teachers have actually conducted field trips. The obstacles listed in going out on field study range from lack of knowledge of appropriate places, lack of time, to safety concerns. The most difficult problem in teaching this unit was preparing proper instructional materials, regardless of teacher's gender, career, and interest. Most respondents let children provide the experimental subjects. Teachers with collection experience tend to provide for the experimental materials themselves. Our Analysis also reveals that more than 70% of the respondents do not have adequate knowledge of the species dealt with in the unit. Gender, career, and interest area of the teachers did not make any difference (p< .05). In the case that proper experimental subjects have not been prepared, VTR, textbooks, and charts were reported as the most frequently used alternative instruction aids. The level of content and amount of knowledge contained in this unit were found to be appropriate. Information on instruction materials and experiment-observation were obtained through the teaching manual or periodicals (58%), information materials on the region(20%), and fellow teachers (12%). Reference books for teachers and materials on the region are perceived to be inadequate in order of importance in the areas of preparation method, level-wise learning guide, experimental observation, and information on species covered in text. Overall, it was judged that the highest concern was with obtaining experimental materials, and teacher's reference books and materials on the region need to be reinforced to allow teachers to more fully utilize them. Development and distribution of proper instruction-learning materials to the children's level is also required.

Background: This study examined age-group differences in the rate, severity, and cost of injuries among construction workers to support evidence-based worker safety and health interventions in the construction industry. Methods: Ohio workers' compensation claims for construction workers were used to estimate claim rates and costs by age group. We analyzed claims data auto-coded into five event/exposure categories: transportation incidents; slips, trips, and falls (STFs); exposure to harmful substances and environments; contact with objects and equipment (COB); overexertion and bodily reaction. American Community Survey data were used to determine the percentage of workers in each age group. Results: From 2007-2017, among 72,416 accepted injury claims for ~166,000 construction full-time equivalent (FTE) per year, nearly half were caused by COB, followed by STFs (20%) and overexertion (20%). Claim rates related to COB and exposure to harmful substances and environments were highest among those 18-24 years old, with claim rates of 313.5 and 25.9 per 10,000 FTE, respectively. STFs increased with age, with the highest claim rates for those 55-64 years old (94.2 claims per 10,000 FTE). Overexertion claim rates increased and then declined with age, with the highest claim rate for those 35-44 years old (87.3 per 10,000 FTE). While younger workers had higher injury rates, older workers had higher proportions of lost-time claims and higher costs per claim. The total cost per FTE was highest for those 45-54 years old ($1,122 per FTE). Conclusion: The variation in rates of injury types by age suggests that age-specific prevention strategies may be useful.

The objective of this research study was twofold; 1) to explore and identify health supportive design factors in Swedish elderly care homes and 2) to understand their usefulness and suggest implication in Korean elderly care settings. A descriptive and explorative method was applied using a combination of field studies and semi-structured interviews. Three study trips were carried out during Sept. $14^{th}$ and Oct. $12^{th}$ 2005; two facilities situated in Stockholm suburbs and one in the south of Sweden. According to this research, the valuable factors to support health and well-being for the elderly are as follows; 1) Community integration: These elderly care homes are generally places close to a residential area center or a city center. Services are often shared between residents and community members at large, consequently there is a flow of "visitors" of all ages connecting with the facility on a daily basis. 2) Homelike environment: A noteworthy aspect of Swedish elderly care homes is keeping the facility appearance as homelike as possible. The associations with home may be explored through the appearance and configuration of both the exterior and interior of the building. These homes seemed to be designed with a conscious aim to create a homelike setting. 3) Small scale approach: Clustering of resident rooms is one method through which the small scale approach can be achieved in larger facilities. With unit clusters, the facility can foster opportunities for social interactions among resident. 4) Accessibility to garden and nature: The courtyard is a well developed concept in planning elderly care homes in Sweden. They are generally safe and easily accessible to the residents. Studying Swedish models may provide practical knowledge of how the physical setting may improve resident's health in Korean elderly care homes.

This study is to analyze essays on the practices of consumption happiness which the students who took the class 'consumption and happiness' wrote. To do this, 108 essays which the students submitted in both semesters in 2013 were analyzed qualitatively. As a result, the 4 themes such as 'reflection on the life of consumption', 'practices', 'changes', 'recognized meanings of the class' were extracted. Firstly, some students were reflective on their acts of consumption in everyday life. They have consumed in an undisciplined, unthoughtful manner and have experienced various negative emotions in their consumption, and have the motive of change. Secondly, the study showed the consumption of clothes, eating, house, leisure, body, digital, wedding is variously included in their practices of consumption. In the category of common practices, 'sharing consumption giving a bigger happiness', 'sustainable consumption caring about the earth and the next generation', 'smart consumption through discipline', 'responsible consumption considering community and producer', 'field trips and consumption of experience as learning' are included, and 'meaningful feeling of happiness through practices' are extracted. Thirdly, they have experienced positive changes such as reduction in consumption desire and increased concern with mind, relationship and conscious consumption. Fourthly, students think of the class as a necessary, useful, practical subject, and have a precious opportunity to learn many aspects they don't think about before, and don't practice, and say that they persistently continue to practice. Therefore, to promote the happiness as a consumer and consumer citizen leader in the society, it's necessary to offer a related class in more universities.
