The purpose of this study is to examine the meaning of Changemaker education and to investigate the significance of Changemaker education in home economics education through a study of growth of learners applying the TEMPS program. To this end, first, the concept of Changemaker education was defined. Changemaker education is an education that changes society in a positive direction through a process of thinking about, learning about, making, and participating(playing) in various problems that we face in real life and drawing out solutions and share he solutions with others. Second, in this reasearch, the direction of Changemaker education is to make them interested in social problems and solve it and to make both the family and the career life happy and healthy by collaborating with other people. The scope of the contents is defined as "the selection of the content elements of the five domains of the child family, diet nutrition, clothing, housing and consumer life". As a way of teaching, we suggested that the TEMPS phase is followed so that the session purpose is achieved. Third, the Changemaker program consists of five steps of TEMPS among the five key ideas of Changemaker education. T(Thinking) is the step of understanding the problem and thinking about how to solve it, and E(Education) is getting the background for the next step. M(Making) is a step to create a target for problem solving, and P(Participation) and P(Play) are steps to Participation and enjoy. S(Share) is a step of changing the society through the result display, SNS sharing, and class presentation. In this study, 12 programs for middle school and 15 programs for high school were developed on the basis of TEMPS level. Each of the programs consists of 2 to 12 unit hours, which add up to 68 hours in the middle school program and 68 in high school. The learners who participated in the Changemaker program for one year (March 2, 2018~December 31, 2018) will experience improvement in many aspects including the linkage of life and education, practical ability, self-directed learning, self-esteem, sense of achievement and self-reflection, sensory observation, and so on.

The purpose of this study is to analyze the structure and contents of the articles in the Journal of Korean Home Economics Education Association to review the research trends during the last decade since 2009. In total, 354 articles from 10 volumes, 40 journal books, were analyzed. This amount to 42.3% of total articles in the JKHEEA for the past 30 years. The results showed that the number of articles in the journal continuously decreased by approximately 5 articles each year. More than half of articles were co-authored as a joint-research between professors and teachers or graduate students. The numbers of pages, tables, figures, and references vary greatly among of the articles published in the JKHEEA. The reviewers and authors would need to check if the pages, tables/figures, or references are indispensable, especially in case there are extremely large number of them. Even though survey research with students as participants is still the most common types of research among recent articles, its percentage is decreasing and diverse research methods such as the analysis of textbook or curriculum literature are being used. Also, research integrating the pedagogy and educational content, and in turn developing and evaluating educational programs is increasing, which indicates that the journal identity has become better-defined. It is advisable that authors select the key words that are more relevant to the title, purpose, and research questions. It is expected that the journal revises the publication regulations so that the issues discussed in this study may be reflected.

Recently, mining facilities have being installed in an underground space according to a social demand for environment-friendly mine development. The underground structures for mining facilities usually requires a large volume of space with width greater than height, and thus the stability assessment of the large-scale underground mine structure is an important issue. In this study, we analysed a factor of safety based on strength reduction method, and proposed a numerical design approach to determining the dimension of underground mine structures in combination with a strength reduction method and a multivariate regression analysis. Input design parameters considered in the present study were the stress ratio and shear strength of rock mass, and the width and cover depth of underground mine structures. The stabilities of underground mine structures were assessed in terms of factor of safety under different conditions of the above input parameters. It was calculated by the strength reduction method, and several kinds of fit functions were obtained through various multivariate regression analyses. Using a best-fit regression model, we proposed the charts which provide preliminary design information on the dimension of underground mine structures.

As the suction pad-supporting bike carrier attached to a car may be subject to an excessive dynamic load due to random vibrations and centrifugal forces during driving, its structural safety is of great concern. To examine this, the finite-element method with a fluid-structure interaction should be used because the pressure on the pad bottom is changed in real time according to the fluctuations of the force or the moment applied on the pad. This method, however, has high computing costs in terms of modeling efforts and software expense. Moreover, the accuracy of computation is not easily guaranteed. Therefore, a new method combining the experiment and computation is proposed in this paper: the bottom pressure and contact area of the pad under varying loads was measured in real time and the acquired data are then used in the nonlinear elastic finite-element calculations. The computational and experimental results obtained with the product under development showed that the safety margin of the pad under the axial loading is relatively sufficient, whereas with an excessive rotational loading, the pad is vulnerable to separation or a local surface damage; hence, the safety margin may not be secured. The predicted contact behavior under the variation of the magnitude and type of the loading were in good agreement with the one from the experiment. The proposed analysis method in this study could be used in the design of similar vacuum pad systems.

The marine ornamental industry has become a multi-billion dollar industry these days. As developing, however, this industry has been criticized for the indiscriminate captures and the destruction of the surrounding environment. To circumvent these problems, it is suggested to breed the organisms artificially. While clownfishes Amphiprion sp. and Premnas sp. are the most famous ornamental organisms in the trade, few studies are yet available on the culture and commercial production of these fishes. These studies were performed to investigate the spawning periodicity, behavior and the habits during egg incubation, and to provide the information on the mass hatching system. The spawning periodicity and frequency were different in 4 pairs under the constant condition, temperature, salinity and photoperiod. On the contrary, the male's behaviors for egg incubation are almost same in the all. The egg-fanning activity of the male increased as the developing eggs reaching to the hatching day. Based on the above results, we designed a new artificial hatching system, the rotating type (RT), and compared it with the aeration type (AT) and spray type (ST) that were previously described. RT showed higher hatching rate of 87.3% than AT (74.4%) and ST (60.5%). Also, there were no significant differences in the hatching rate regardless of the number (2, 3, 5) of hatching plates. We suggest RT may accommodate various number of hatching plates and constitute a better hatching system for clownfishes.

기술혁신과 제도변혁의 와중에서 미국을 위시하여 우리나라, 일본, EU, 싱가포르등 세계 각국들은 경쟁적으로 2010년까지 초고속정보망을 구축할 것을 계획하고 있다. 더나아가서 미국 정부는 세계적인 초고속정보망 (Global Information Infrastructure: GII)을 구축하는 것을 계획하고 있다. GII 추진을 주도하고 있는 미국을 영상, 소프트웨어, 방송, 게임 등의 각종 멀티미디어 서비스의 절대적 경쟁력을 미국에서 뿐만 아니라 GII를 통해 세계시장으로 확대, 보호하겠다는 전략적 의미를 갖고 있다고 볼 수 있다. 미국의 GII 추진전략에 대응하여 일본은 AII 라는 아시아판 초고속통신망 구축과 개방화를 제안하였으며, 우리나라 정부는 APII라는 이름으로 아시아, 태평양지역 국가들을 대상으로 하는 초고속통신기반을 구축할 것을 제시하였다. 한국의 APII전략은 아시아, 태평양 지역 중심으로 한국의 국가적 위상을 제고하는 한편 우리나라 기업의 국제진출을 위한 전진기지로서의 활용측면에서 유효하다는 의미로서 제시하였다. 그러나, 우리나라가 제시한 APII의 청사진은 세계 정보통신시장을 중심으로 볼 때 경쟁력을 갖고 있는 정보통신부분이 반도체이외에는 전무하다는 측면에서 잘못하면 APII라는 전략은 미국이나 일본의 정보통신망 구축에 이용당할 가능성이 높은 무의미한 전략적 의미를 갖고 있는 것으로 보인다. 따라서 본 연구에서는 미국이 구축하고자 하는 GII체제와 병행하여 우리나라 정보통신산업을 육성, 발전시키기 위한 대응전략이 어떤 방향으로 전개되어야 할 것인지를 제시하기 위하여 GII가 갖고 있는 전략적 의미를 산업조직측면에서 살펴보고자 하였다. GII구축으로 인하여 세계의 정보통신 대기업은 초대기업으로 성장할 수 있는 기회이지만 중소기업 역시 대기업으로 성장할 수 있는 기회이다. 따라서 우리나라 정부는 정보통신산업정책을 초고속망 구축위주인 대기업 중심체제에서 중소기업이 참여 가능한 통신기기산업이나 멀티미디어 산업으로의 유인전환을 촉진할 필요가 있다. 다음으로 GII 구축에 따라 정보통신기업의 전략적 제휴 내지 합병이 활발히 촉진되고 있는 상황을 감안하여 볼 때 국내의 통신산업 역시 전략적 제휴 내지 합병이 가능할 수 있도록 정부규제를 완화할 필요가 있다. 그리고 정보통신서비스업체 역시 나름대로 독과점 산업인 통신기기업체내지 소프트웨어 산업으로의 진출이 가능할 수 있도록 상호진출을 허용할 필요가 있다고 본다. 이를 위해서 우리 나라 정부 역시 미국처럼 새로운 통신개혁법을 만들 필요가 있다. 새로운 통신개혁법의 핵심적인 사항으로서 첫째, 통신과 CATV간의 상호진입을 허용, 둘째, 통신사업자가 통신관련 기기산업에 참여할 수 있는 규제완화를 허용, 셋째, 유아단계에 있는 소프트웨어 및 컨테트산업을 육성하는데 산업육성책 수립 등을 적극적으로 추진하여야 할 것이다. 그리고 현재 국내 재벌기업들로 구성되어 있는 기반산업을 지원하는 기술개발 지원체제와 육성정책을 소프트웨어 및 컨텐트의 응용산업으로 개편할 필요성도 제시되며, 이를 위해 범부처 차원에서 소프트웨어 및 컨텐트 육성정책을 지원하는 종합적인 대책을 마련해야 한다고 본다.

Environmental regulations have recently been strengthened. Consequently, floating LNG(Liquefied Natural Gas) power plants are being developed, which are new power generation plants that generate electricity by utilizing LNG. A floating LNG power plant generates BOG(Boil-Off Gas) during its operation, and the system design of such a plant should be capable of removing or re-liquefying BOG. However, the design of an offshore plant differs according to the marine requirements. Hence, a process simulation model of the BOG re-liquefaction system is needed, which can be continuously modified to avoid designing the floating LNG power plant through trial and error. In this paper, to develop a model appropriate for the floating LNG power plant, a commercial process simulation program was employed. Depending on the presence of refrigerants, various BOG re-liquefaction systems were modeled for comparing and analyzing the re-liquefaction rates and liquid points of BOG. Consequently, the BOG re-liquefaction system model incorporating nitrogen refrigerants is proposed as the re-liquefaction system model for the floating LNG power plant.

그 동안 지속적인 경제성장을 바탕으로 한국의 생명보험산업은 양적으로 성장하였다. 그러나 내면을 살펴보면 외형을 떠받칠 만큼 내실있게 성장했는지에 대해서는 많으 의구심을 갖게 한다. 현실적으로 경제성장을 바탕으로 한 외형성장은 한계를 맞을 수 밖에 없으며, 이제는 질적인 내실을 기하기 위해 그 동안 소홀히 했던 보함산업의 전반의 체질개선이 필요하다. IMF이후 경영이 부실한 보험사들이 퇴출되면서 전면적인 개편이 이루어졌고, 또한 보험사 내부에서도 전반적인 개혁의 필요성을 인식하여 여러 방면으로 방안을 구체화하고 있다. 본 논문은 이러한 상황하에서 생명보험산업의 기존 문제점 개선방안의 일환으로, 보험산업의 가장 핵심분야라 할 수 있는 언더라이팅 분야의 국내현황을 살펴보면서 보험선진국의 제도 및 운영현황과 비교 분석하여 부문별 문제점을 도출하고, 그에 따른 개선방안을 제안하게 되었으며, 본 논문에서 제시된 개선방안을 요약해 보면 다음과 같다. 첫째, 언더라이팅을 신속 정확하게 수행하고 도덕적 위험을 배제하기 위하여 개선된 정보교환시스템 제도를 구축해야 하며, 사정자료의 수집업무를 전문기관에게 아웃소싱함으로써 비용절감을 기하여야 한다. 이와 아울러 모집인의 전문성을 제고시켜 보험계약 청약서와 모집인 보고서가 정확하게 작성되도록 하고 언더라이팅 실적과 연계한 인센티브제도에 의하여 모집수당이 지급되도록 하여 언더라이팅이 효과적으로 수행되도록해야 할 것이다. 둘째, 언더라이팅기법의 선진화를 기함으로써 위험에 상응하는 보험료를 부가하여 위험에 노출되어 있는 가망고객의 보험가입율을 높이고, 보험사고 발생시 실질적인 보험혜택을 누리도록 하여야 한다. 이를 위한 실천방안으로 의적 직업적 재정적 언더라이팅 선진기법을 도입하여 각 부문의 역량을 강화해야 할 것이다. 특히 제도적으로 개인신용정보의 언더라이팅 활용이 제한되어 있는 현실에서 이를 법제도 내로 흡수하면서 개인의 사생활 유지라는 목적을 동시에 달성되도록 하는 재정적 언더라이팅 기법의 강화가 특히 중요하리라 생각된다. 아울러 언더라이팅 업무를 효과적 효율적 수행을 통해 일관성 있는 의사결정이 이루어질 수 있도록 지원하는 언더라이팅 시스템구축을 통해 정형화된 인수과정은 결정시스템화하고, 복잡한 위험의 경우 자문 시스템으로 운영하여 간단한 언더라이팅 업무는 구축된 시스템을 통해 즉각 해결함으로써 시간을 절약할 수 있고, 언더라이팅 인력은 보다 전문적인 부문에 집중하도록 해야 할 것이다. 마지막으로, 비표준위험시장의 활성화를 위해서는 현재의 제약조건인 생명보험 상품개발을 세트형에서 조립형으로 전환하고, 재보험으로 위험을 분산하여 비표준위험의 인수를 증대하여야 할 것이다. 이와 더불어 언더라이팅 과정에서 얻어진 피보험자의 사정자료를 활용하여 고객에게 필요한 의료정보 등을 제공함으로써, 피보험자와 유대관계를 돈독히 하여 기존계약이 계속 유지되도록 하며, 추가계약이 이루어지도록 해야 할 것이다. 이상과 같은 비표준위험의 언더라이팅 개선방안이 보다 효과적으로 수행되고 발전하기 위해서는 통계축적 및 관리, 전문 언더라이터 양성, 전산을 이용한 언더라이팅 확대 등이 이루어져야 하므로 향후 이에 대한 집중적인 연구가 있어야 할 것이다.

Ran Gang is a huge, attractive river which meanders through Seoul, the capital of South Korea. However, during the modernization of Seoul, the river gradually lost its natural beauty and healthy condition. Han Gang Renaissance is a project to upgrade the look of the Seoul waterfront, by overcoming this disaster and reorganizing the surroundings of Han Gang. This research articulates the design strategies and description of the prizewinning work of the International Design Competition for Yeouido Riverside Park that was linked to the Han Gang Renaissance Project. There are three key points that basically speak to the identity of the new waterfront, Yeouido Riverside Park. First, the current day Yeouido was recreated as an artificial island through the rapid expansion of the city and the initiation of the shore protection works. However, because it is the only island still remaining that shows the history of Han Gang, the park was designed to be the place which preserves the lyric of sand island and the emotional memory of riverside. Secondly, among the six districts of the Han Gang Renaissance Project, the two districts that are facing each other, Yongsan and Yeouido, are the central areas promoting international finance and business. Despite Yongsan's complete urban image, the exquisite harmony of pastoral scenes and skyscrapers of the Yeouido waterfront is presented to develop an active mutual relation with Yongsan. Lastly, this design scheme re-establishes the relationship between this competition's site, Yeouido Riverside Park, and a neighboring site, Yeouido Park.

In this study, a source locating technique applicable to transversely isotropic media was developed. Wave velocity anisotropy was considered based on the partition approximation method, which simply enabled AE source locating. Sets of P wave arrival time were decided by the two-step AIC algorithm and they were later used to locate the AE sources when having the least error compared with the partitioned elements. In order to validate the technique, pencil lead break test on artificial transversely isotropic mortar specimen was carried out. Defining the absolute error as the distance between the pencil lead break point and the located point, 1.60 mm ~ 14.46 mm of range and 8.57 mm of average were estimated therefore it was regarded as thought to be 'acceptable' considering the size of the specimen and the AE sensors. Comparing each absolute error under different threshold levels, results showed small discrepancies therefore this technique was hardly affected by background noise. Absolute error could be decomposed into each coordinate axis error and through it, effect of AE sensor position could be understood so if optimum sensor position was able to be decided, one could get more precise outcome.
