The concept of the "Seidenstrassen" (Silk Road) was created by the German geographer F. von Richthofen (1833-1905) in 1877. The "Seidenstrassen" means communication between China and the Roman cultural area. To prove the route of dissemination of silk, Richthofen not only focused on geographical substantiality, based on the routes of the Chinese Zhang Qian and the Roman Ptolemy, but also on etymological, historical, and religious sources. In fact, his Silk Road concept has the trade of silk as well as the humanistic ideas of cultural exchange. It is worth noting that in his book China, Richthofen presented the Silk Road as a space-time concept that considers the length of space as well as the length of time by highlighting humanistic examples that came into modern times through the Sea Route. Later, the English term "Silk Road" appeared in 1938, the Japanese term "シルクロ-ド" (sirukurodo) in 1939, and the Korean term "실크로드" (silkrodeu) in 1952.

최근 국내외적으로 친환경에 대한 국제적인 관심이 증가됨에 따라, 건설 산업 측면에서도 친환경적인 생산시스템 구축을 위한 노력이 요구되고 있다. 이에 부응하기 인해 건설폐기물 재활용과 관련하여 다양한 실무와 연구가 진행되고 있지만, 현장조사결과 '건설현장'과 '폐기물 처리업체'에서 수행하고 있는 폐기물 처리과정 및 처리방안이 상호 효과적으로 지원하고 있지 못하여 폐기물 재활용 저해요소로서 작용하고있는 실정이다. 따라서 본 연구에서는 건설폐기물의 재활용을 활성화시키는 방안으로써, '건설현장'과 '폐기물 처리업체'의 건설폐기물 처리과정에서 폐기물 재활용을 저해하는 요인을 도출하고, 이를 기반으로 개선방향을 제시하고자 한다. 이러한 연구목표를 달성하기 위해, 먼저 광범위한 문헌조사를 통해 대표적인 건설폐기물 종류(폐 콘크리트, 폐 아스팔트, 폐 토사, 폐 벽돌, 폐 합성수지, 폐 목재)를 선정하였고, '건설현장'과 '폐기물 처리 업체'를 대상으로 전문가 면담을 실시하여, 이들 개별 폐기물의 처리과정 조사를 통해서 폐기물 재활용 저해요인을 조사하였다. 또한, 전문가 면담 결과로 파악된 폐기물 재활용 저해요인을 설문조사를 통해 중요도 및 우선순위를 파악하였다. 이를 기반으로 현행 건설폐기물 처리 프로세스를 개선함으로써, 재활용 효율화 방안을 제시하였다.

The auther reported the distribution of fisheries high schools and arrangement of curriculum in Japan in the forward report, and describes on the outer apparance and substantiality of education of fisheries high schools in Japan in the present report. 1. The rate of population to the number of fisheries high school shows 2,350 thousands in Japan, compared with 3,250 thousands in Korea. Then the rate in Korea is 1.4 times as high as that in Japan. 2. The rate of pupil to the whole regular instructors for fundamental subjects and for vocational subjects in the fisheries high schools, and also the rate to the instructors for vocational subjects show 10.4 and 16.3 in Japan, compared with 18.2 and 30.2 in Korea. Then the rate in Korea is 1.8 times as high as that in Japan. In addition to the instructors for vocational subjects. trainer and assistants for technical training-are employed in Japan compared with no such instructors or assistants in Korea. Then the rate of pupil to the whole instructing staffs in Korea is 2.4 times as high as that in Japan. 3. 81 percents of training ships in Japan are larger than 400 gross tons, which is extremely higher to that in Korea. The rate of gross tonnage of the ships to the number of trainees shows 6.2 tons in Japan compared with 1.1 tons in Korea. Also such large dimensioned training ships are newly built every other 12 years. the construction cost per 1 gross ton of such ships are said as 2.5 to 3 million yen, which corresponds to 15 to 18 million wons, and is over 3 times as much as that in Korea. 4. The basic education on the marine field is widely diffused in Japan. For an example, swimming pools are prepared not only in fisheries high schools but also in primary schools although it is rate even in fisheries high schools or colleges in Korea. 5. Almost all provinces which locate on the seashore have at least one fisheries high school and the curriculum is arranged to match the needs of local districts, then the management of school is tightly linked to the local government. 6. Entrance system is also flexible and recommended entrance system for successors of fishermen is settled. 7. Re-education of instructors for the new subjects which should be prepared to match the demands of ages are supported by local government in the aspect of time and budget. 8. The special two-year course for advanced seamen' s education is attached to some fisheries high schools and the graduates are qualified to get the third grade marine officer's or engineer's liscence.

Recent years, many industries acknowledge that environmental substantiality of products must be an essential role and it is one of the major importances for industries to consider the environmental impacts of products at the early stages of product development. This study investigated eco-design parameters and $CO_2-eq$. emissions in each stage of raw material acquisition, manufacturing, transportation, use and disuse in life cycle of touch monitor stand based on Eco-Design. In this study, to fulfill of Eco-Design, the environmental impact assessment of through LCA(Life cycle assessment) was carried out with benchmarking monitor stand and we suggested the direction of new design of touch monitor stand mechanism based on eco-friendly considerations. New design based on LCT(Life Cycle Thinking) showed that the following eco-friendly considerations at the early stage of design to be helpful to reduce GWP(Global Warming Potential) [kg $CO_2-eq$.] in new monitor stand development and it is necessary for Eco-Design process of the product.

Research on strategic Code-Switching (CS) of second language learners in teaching English in English (TEE) program provides an elaborate framework for analyzing how learners manage to express themselves in spite of their limited knowledge of the target language. This research presupposes that L2 learners' CS presents innovative solutions for communicative strategy, and that CS used as communicative strategy can promote L2 learners' language acquisition. The major questions of current research involve examining the significant patterns of different functions of CS in L2 learners' interaction and investigating L2 learners' CS styles according to the different functions of CS. The implication of CS utility is regarded as a teaching technique in the TEE program. Recorded transcript is analyzed to trace the same pattern and the categorization of CS as well as to recognize the functions of CS and their ratio. Hence, this leads to the conclusion that learners' negotiation between code selection and communication intention occurs in patterns. The learners' CS tends to be predictable, reproductive, and systematic, as one of the language acquisition phases. Therefore, the attention to the CS in the TEE program should be redirected in communication substantiality toward the principles of pragmatics. As an additional advantage of the CS analysis, this research elaborates on a conceptual acceptance of CS as a set of learners' strategies in the TEE program.

Fuel cells are currently attracting tremendous interest because of their huge potential in stationary applications, in terms of substantiality of our energy use. They also offer environmental advantages, combining significantly higher efficiency with very much lower emission of SOx, NOx, and residual hydrocarbons, and significantly reduced $CO_{2}$ emissions compared to conventional power generation. The molten carbonate fuel cell (MCFC) was introduced from Fuel Cell Energy(FCE), which the one MCFC was operating by LNG and the other was operating by ADG. The ADG contains normally CH4, CO2 and various impurities such as sulfur compounds and siloxanes. Using the ADG as a fuel, MCFC have the potential to provide significant environmental and economic benefits. However, such impurities would be harmful to fuel cells. In this work, a purification process for the ADG was designed and installed in order to utilize the gas as a fuel for MCFC.

Korea is expected to become a super-aged society by 2050. Given an aging population and the increasing pressure for the early retirement, a sufficient social safety net for elderly population becomes important. The Korean government introduced public reverse mortgage program in 2007, which is a product for aging seniors and the elderly, The number of reverse mortgage subscribers has also steadily grown. The demand continues to grow, but the reverse mortgage over a long period of time is a highly uncertain and risky product in the position of guarantee or lending institution. Thus, suitable demand prediction of the reverse mortgage subscribers is necessary for stable and sustainable operation. This study uses a Bass diffusion model to forecast the long-term demand for reverse mortgage and provides insight into reverse mortgage by forecasting demand for stability and substantiality of the loan product. We represent the projections of new subscribers on the basis of the data obtained from Korea Housing Finance Corporation. Results show that potential market size of Korean reverse mortgage reaches approximately 760,000-1,160,000 households by 2020. We validate the results by comparing the estimate of the cumulative number of subscribers with that found in literature.
