유상규,강호상,오재영 한국포장학회 2023 한국포장학회지 Vol.29 No.2

The cosmetics industry faces a significant challenge in addressing the decreased recycling rate of cosmetic containers due to the composite materials used to meet consumers' aesthetic satisfaction. To address thees issues, eco-friendly packaging solutions such as refill packaging and single-material use have been developed. However, the market for eco-friendly cosmetics packaging requires a product that meets consumers' demands for aesthetics, sensitivity, and eco-friendliness while also performing as well as existing products. This study presents a solution to the challenge of the decreased recycling rate of cosmetic containers by developing a new cosmetic packaging product for cream for-mulations. The product features an easily separable and dischargeable internal refill container, while maintaining the design aesthetics of the external container. Through various tests, the product was shown to be of equivalent quality and performance to existing cream cosmetic packaging, with no leakage or defects observed. Furthermore, the use of a sin- gle-material polypropylene refill container is expected to contribute to the improvement of the plastic recycling rate.

柳相圭 충주대학교 1998 한국교통대학교 논문집 Vol.33 No.2

Emphasizing the organic relationship between the central place and its hinterlands to develop urban and rural areas in harmony is the main concept of urban-rural unification. To manage the unified region comprehensively and systematically, the spatial characters of each sub region in unified administrative districts should be analyzed. The purpose of this study is the examination of the spatial characters of each sub region in the Chungju agropolitan region by analyzing population and land use pattern. This study, first, reviews the phase of Chungju agropolitan region within the all urban-rural unified cities. Second, it examines age structure as a result of the population change. Third, the regional land use pattern is compared to the relation of the population change. As a result, from the viewpoints of two space, urban and rural, there are heterogeneities in the age structures and the land use patterns. But there are also some hierarchies between each sub regions of the Chungju agropolitan. Thus, in the case of Chungju, carrying out more detail and systematical researches in the economy and the social respect to add to studies on the spatial characters of each sub region with the population and the land use pattern, it will be the bases to achieve the ultimate goals of urban-rural unification.

유상규,강호상,오재영 한국포장학회 2022 한국포장학회지 Vol.28 No.3

화장품용 펌프는 복합재질의 내부 부품들과 복잡한 구조 로 인하여 소비자들이 재질별로 분리 배출할 수 없는 구조 를 이루고 있으며, 특히 금속 스프링을 사용하고 있어 재활 용률이 현저히 떨어졌다. 하지만 최근 국내·외에서 환경오 염으로 인한 다양한 규제 및 소비자의 인식 변화로 친환경 적인 제품의 수요도 급격히 증가하고 있으며, 이에 따라 화 장품 업계에서도 재활용률을 높이기 위해 다양한 시도가 진 행되고 있다. 또한 아직 국내·외 플라스틱 화장품 용기의 재활용률이 20% 내외로 낮은 상황에서 친환경 화장품 용 기 세계시장 선점과 국내 포장산업 활성화를 위해서는 기 술적 차별화와 동시에 선진기업 수준의 품질 성능을 갖춘 화장품용 고성능 펌프의 개발이 필요하다. 따라서, 본 연구 에서는 단일재질(PP)로 구성된 0.2 ml 고성능 펌프를 개발 하였으며, 실험을 통해 감압 시 내용물의 누수와 용기 변형 이 없으며, 누름강도 14.8~17.5N, 토출량 편차 2.3~8.8%, 초기 공타 4회로 기존 금속재 스프링을 사용한 복합소재 펌프와 대등한 수준의 품질 성능을 확인할 수 있었다. 또한, 단일소재를 사용하였기 때문에, 향후 국내·외 친환경 화장 품 용기 시장 점유율 확대와 함께 플라스틱 재활용률 향상 에 기여할 것으로 기대된다. Cosmetic packing materials tend to be difficult to recycle when discarded due to the cosmetic industry’s pursuit of aesthetics, functionality, and high value-added design. Pump packaging, which is widely used for the good preservation and discharge of cosmetics contents, is difficult to be separated and recycled because of a metal spring, which is in charge of pump resilience. In this study, a polypropylene spring was developed to replace the existing metal spring to improve the recyclability of the pump packaging for cosmetics, and was uni-materialized by applying to the cosmetic packing materials with 0.2 ml of discharge amount. In addition, performance test was conducted to verify the equivalence with the existing metal spring pumps as grounds for the commercialization of metal-free uni material pump packaging. The decompression leak test showed no leakage and displayed 14.8~17.5 N of pressing strength, 2.3~8.8 % of deviation in dispensing volume, and 4 occasions of pumping for initial discharge.

This Study intents to figure out the spatial structure of university campus using space syntax. Space Syntax is an objective and percise quantitative method of description that can indicate how well built environment functions. This paper attempted to represent the spatial structure as a axial map, and analyze the spatial configuration in terms of space syntax model. On the basis of the analysis, an alternative was proposed, in respect of pedestrians and vehicles movement. Preparing the spatial configuration values in the alternative with the present's, the change of some spatial structure, proposed in the alternative, improved mean depth, control value, and integration of study area. Thus, in the planning process of university plan, planners can use the space syntax methodology to control the roots of pedestrians and vehicles in campus.

It has been well recognized that proper use of information and communication technology can facilitate teaching - learning process in many ways, and as a new way of the educational reform and the improvement of educational construction, information technology as well as computer is changing the way of education from delivery education to direct education They are also changing the teachers role from a information controller to a guide and coach. On this study, I made a questionnaire based on the documents related to use of information Technology in Education to grasp the actual situation of use of Information Technology in Education of high school teachers. The special features of the questionnaire are as follows. First, it investigated and analyzed the problems related with teacher training systems for educational information programs. Second, it analyzed the degrees of teachers using facilities by investigating the use of computer lab, the use of computers for teachers, the use of the facilities for improving teaching methods, and the degree of interest in constructing a basis of information technology in education. Third, It analyzed the degrees of using information on use of information Technology in Education by Investigating the use of the multimedia teaching and learning materials which are already developed and spread, and the use of the educational network as well as Internet. Fourth, It Investigated and analyzed the degree of high school teachers awareness of hardware s repair and maintenance. Finally, On the side of teachers recognition for the use of information technology in educational administration, it analyzed the necessity of human resources for the use of information technology in educational administration, the problems of the use of information technology in educational administration, the actual situation of the use of information technology in school affairs, the prospect for the use of information technology in educational administration. The result of this study is as follows. 1. Considering the competence and willingness to promote the information-oriented education in the field of each school, the government of education should make the school s autonomy extended, and also make a general plan for information education which can keep pace with and accord with that of each school level. 2. In the case of the schools in which there are a principal with a high mind of the information-oriented and teachers with capability to push on with the information-oriented education, they should have priority to be supported. 3. When teachers who are responsible for computer education at their own schools take a wholly charge of the information-oriented educational foundation establishment, they should have more chances to study and train to develop the skills. The government of education needs to compose and manage some expert teams wholly responsible for the repair and maintenance of computer H/W and S/W. Each school should try to make a contact with expert enterprises for the repair and maintenance of course wares. 4. The S/W of good quality should be developed and supplied to each school level. The government of education has to make a sufficient budget, allow capable teachers to participate in the S/W development personally or to cooperate with private enterprise, and support those teachers with materials and budget enough to develop good quality softwares. 5. More opportunities are need for teacher training programs for ICT
