There are increasing public concerns that the disposal of most synthetic carbon-based plastics is a great threat to the environment. These have led to intensive research and development of degradable plastics, such as biodegradable plastics, photodegradable plastics, and multi-degradable plastics. Although these degradable plastics may not completely replace common synthetic plastics, these minimize environmental impacts caused by non degradable plastics. Photodegradable plastics are synthetic polymers into which have been incorporated copolymers or light-sensitive additives to weaken the structural bonds in polymer chains when exposed to UV radiation. A better understanding of photodegradable plastics, which also play an important role in the degradation of multi-degradable plastics, will expand the usage of degradable plastics. The aim of present article is to review the formation, degradation mechanism and properties of photodegradable plastics.

The thickness dependent electrical, structural, and optical properties of ZnO films grown by atomic layer deposition (ALD) at various growth temperatures were investigated. In order to deposit ZnO films, diethylzinc and deionized water were used as metal precursor and reactant, respectively. ALD process window was found at the growth temperature range from $150^{\circ}C$ to $250^{\circ}C$ with a growth rate of about $1.7{\AA}/cycle$. The electrical properties were studied by using van der Pauw method with Hall effect measurement. The structural and optical properties of ZnO films were analyzed by using X-ray diffraction, field emission scanning electron microscopy, and UV-visible spectrometry as a function of thickness values of ZnO films, which were selected by the lowest electrical resistivity. Finally, the figure of merit of ZnO films could be estimated as a function of the film thickness. As a result, this investigation of thickness dependent electrical, structural, and optical properties of ZnO films can provide proper information when applying to optoelectronic devices, such as organic light-emitting diodes and solar cells.

The purpose of this study is to establish a new management strategy to meet customer needs of discount stores as customers demand higher and more diverse services in addition to low prices. An empirical analysis on consumers to explore the structural relationships between the quality, environmentally friendliness, consumer perception, service value, and emotional response of retail ready packaging (RRP) in discount stores in order to find out how they affect customer satisfaction and repurchase intention. First, it was confirmed that the RRP quality of discount stores that affects customer satisfaction is mediated by the emotional response. Second, it was found that RRP in discount stores should continue to devise strategies to improve service quality along with efforts to provide more benefits perceived by customers to increase customer satisfaction and repurchase intention. Third, it was confirmed that the RRP image of discount stores has a positive (+) effect on service value, emotional response, customer satisfaction, and repurchase intention.

Paper tube industry for synthetic fiber packaging has approximately 200 billion won of market size in Korea, while any significant research has not done yet about physical characteristics of paper tubes. This study was conducted to find out a adequate structure of paper tubes by changing compositions of paperboards, size of tubes, and makers. Parallel compression strength was not only rely on compositions of paperboards, but also largely impacted by structural design of paper tubes.

While green packaging related concerns are mainly studied in developed countries, there is a lack of knowledge to observe purchase behavior toward green packaging in developing countries, especially in Vietnam. Buying green packaged products in FMCG is not required to trade-off between sustainability and product performance. Hence, this present research aims to understand the gap attitude - behavior existing on FMCG green packaged products among Vietnamese young consumers with psychosocial factors (environmental concern, environmental knowledge of green packaging and green trust) and contextual factors (availability of desired green packaging and product attributes). With a sample size of 396 respondents, data was collected by convenient sampling method and then was analyzed using structural equation modeling. The results reveal that all psychosocial factors are positive related to attitudes while purchase behavior is positively influenced. The findings also report that contextual factors have positive impacts on purchase behavior, which proves the important role of contextual factors in influencing consumer choices. It suggests that green packaging is receptive to Vietnamese young consumers but it should be considered within product-related context to enhance the difference in sustainability among similar FMCG products. Practical implications for marketers and future researches have also been discussed at the end of study.

이 연구에서는 자동차용 에어백 작동에 쓰이는 가속 센서에 대해, 그 실장 방법에 따른 신호 전달 차이를 해석하였다. 실장 방법은 기존에 쓰이는 하우징을 사용한 모듈 형태와, 센서를 직접 자동차의 구조물에 접합재를 사용하여 부착하는 두 가지 방법을 고려하였다. 신호 전달을 분석하기 위하여, 충격 실험 장비가 구축되었고, ㄷ자형 알루미늄 채널을 이용하여 그 표면에 기존의 모듈 채결 방법과 센서를 직접 부착하는 방법을 사용하여 시편을 제작하여, 충돌 실험 후 측정된 파형을 비교하여 그 차이를 분석하였다. 또한 유한요소법을 이용하여 충격 실험을 모사하였고, 계산 결과를 실험 데이터와 비교하였다. 그 결과, 기존의 모듈형태의 부착 방법보다, 이 연구에서 제시된 접착제에 의해 직접 부착된 센서가 측정한 신호가 상대적으로 잡음없이 깨끗하고 강한 것을 알 수 있었으며, 또한 에어백 센서와 같은 MEMS 센서는 부착 방법에 따라 주변의 간섭 효과에 의해 그 성능이 크게 변하는 것을 알 수 있었다.

As one of the core technologies in the field of the optical communication with WDM, the optical cross connector with movements of micro mirrors is getting important day by day. The packaging structure of 2-dimensional NxN MOEMS switch should be determined by the harmonization of the following items such as the geometrical compatability between optical and structural components, the characteristics of optical input and output parts with device, and the electrical performance for the operation of micro mirrors. Therefore, the packaging process could be defined as the integrated technology completed by the optical and electrical science and the material science for the understanding of its thermo-mechanical properties with packaging materials. In the present study, the harmonization between the optical and structural components as well as the optical characteristics of lens system used will be investigated.

The internal residual stresses within the multilayered structure with shan interface induced by the difference in thermal expansion coefficient between the materials of adjacent layers often provide the source of failure such as delamination of interfaces and etc. Recent development of the multilayered structure with functionally graded interface would be the solution to prevent this kind of failure. However a systematic thermo-mechanical analysis is needed fur the customized structural design of multilayered structure. In this study, theoretical model for the thermo-mechanical analysis is developed for multilayered structures of the Al-$SiC_p$ functionally graded composite for electronic packaging. The evolution of curvature and internal stresses in response to temperature variations is presented for the different combinations of geometry. The resultant analytical solutions are used for the optimal design of the multilayered structures with functionally graded interface as well as with sharp interface.
