This study was carried out to research on the compression strength of paper cups and to investigate the possibility to recycle them as pallet blocks. The compression strength of paper cups was increased with the increase of the number of them showing the value between 0.5 and $5.9kg/cm^2$. The compression strength of the pallets using paper cups as the blocks was increased with the increase of the number of paper cups per block. Especially, the compression strength of the pallet with ten paper cups per block showed the value above 1000kg.

This study examined the effect of environmental alteration and prompts on recycling behavior. An A-B-BC with a control condition design was employed. Subjects in this study were college students, professors, and employees at a university building. After a baseline phase, environmental alteration was I effect in the next phase and both environmental alteration and prompts were in effect in the final phase for the control condition. The environmental alteration consisted of providing four separation containers for the paper cups, cans recyclable paper, and the disposable on each floor in the building. The prompts consisted of providing the information about the importance of environmental preservation and how to separate the materials in the appropriate containers using an information board and pamphlets. The dependent variables were (1) the number of cans collected in can container, (2) the number of paper cups collected in cup container, (3) the rate of correct separation of cans, (4) the rate of correct separation of paper cups, and (5) the weight of disposable. The rates of correct separations of cans and paper cups were obtained by calculating the percentage of thenumber of recyclable cans and paper cups in the corresponding containers. The results indicated that environmental alteration had positive effects on all the dependent variables. Also, when the prompts were added to the environmental alteration, the incremental effect of the prompts was demonstrated. The implications and limitations of theses findings were discussed and the direction of future studies was also proposed.

본 연구는 황남대총 남분 출토 패각류 중 용도가 불명확한 금동제패각장식구(金銅製貝殼裝飾具)에 대한 연구조사이다. 금동제패각장식구로 조사 보고된 이 유물은 조사결과, 이전 발굴유물부터 현재까지 발견되지 않았던 앵무조개로 만든 잔으로 확인되었다. 암모나이트와 가장 유사한 종으로 알려진 앵무조개는 껍질 표면에 등갈색 방사대와 껍질 안쪽의 격벽, 격벽 중앙에 체관을 가지고 있다. 앵무조개잔[이하 앵무배(鸚鵡杯)로 표기]은 중국에서 제작되어 사용된 것으로 알려져 있으며, 현존하는 유물로는 중국 서진 및 동진시기의 무덤에서 발견된 금속으로 장식된 앵무배 3점 뿐이다. 일본에서는 아직 확인되지 않았으며, 한국에서는 이번 조사를 통해 황남대 총 남분 출토품에서 앵무배를 확인하였다. 본 논고는 연구 조사된 앵무조개의 생물학적 특성 및 국외 발굴 출토사례 및 기초자료를 위한 분석조사를 실시하였다.

"Drifting cups on a meandering stream" is a same originating from the ancient China. It takes advantage of the stopover of the cup at the different positions on a meandering stream to choose a person sitting on the bank to participate the game. In this paper, a model is devised to make the cups move around or stop at some place on the stream as required by the game. A typical flow field Is abstracted and studied using the PIV technique and the topological analysis. Some motions of the cup on the stream have been explained in the mechanics theory.

Experimental studies have been carried out to obtain uniform cups by one operation of backward extrusion. A lot of factors on dimensional accuracy of backward extruded cups are billet material, billet shape, punch shape, punch velocity, geometry of tool, tool material, and lubrication etc. In manufacturing cup-shaped parts by backward extrusion, it is very important to design the initial billet shape or the preform. The objective of this paper is to find that the shape of the initial billet is related to dimensional accuracy and also to manufacture the more accurate product simultaneously reducing the loss of material as forming the shape of the initial billet by means of upsetting.

To analyze royal nad Chinese envoy procession, and sacrificial rite of Chinese envoy for Choson Dynasty, the author studied historic book-Youngjeob Dogam Sajechong Euigwae of Choson Dynasty(1609 year) in which Chinese envoy procession for sacrificial rite in Choson Dynasty were described. The results obtained from this study were as follows. 1. Sacrificial rite of Chinese envoy for Choson Dynasty were Yellow paper burning and performing a sacrificial rite of chinese envoy. 2. Order of Chinese envoy procession for Yellow paper burng and performint a sacrificial rite of Chinese envoy, was civil and military officers, flag procession, drum, palanquin of incense, palanquin of guneral oration, palaquin of material for guneral expenses, palanquin of rich viands and sumptuous fare and Chinese envoy. 3. Things offered in sacrifice of Yellow paper burning were fried cake made of wheat flour, honey and oil, fried gutinous rice cake, patterned savory cake, fruits, meat fish and others broil, slices of boiled beef, soup, stew, noodles, 3cups of alcohol, rice cake and water. 4. Things offered in sacrifice of performing a sacrificial rite of Chinese envoy were a cattle, a hog, a sheep, 3 cups of alcohol and etc.

종이컵 성형기는 배럴캠, 인덱스, 터렛, 모터 등의 많은 부품으로 이루어진다. 그 중에서 배럴캠은 기계의 주 구동부이다. 배럴캠이 회전하면서 인덱스에 고정되어 있는 롤러를 밀어준다. 그리고 인덱스와 연결된 터렛이 회전하면서 종이컵이 만들어진다. 따라서 종이컵 성형기의 성능은 배럴캠에 큰 영향을 받는다. 이번 연구에서는 배럴캠을 설계하는 프로그램이 MATLAB 을 이용하여 개발 되었다. 프로그램은 배럴캠의 프로파일을 만들어준다. 이 프로파일은 3 차원 CAD 프로그램을 이용 하여 3 차원 CAD 모델로 변환된다. 이 3 차원 CAD 모델과 배럴 캠의 3 차원 레이저 측정을 통해 생성된 모델을 포함하는 동역학 모델을 생성하였다. 그리고 동역학 모델을 검증하기 위해 기계의 인덱스의 회전각이 고속카메라를 이용하여 측정된다. 동역학 모델의 회전각을 비교하여 프로그램을 검증한다.

Due to the outbreak of the COVID-19, self-service technology is widely used in Korea, and demand for disposable cups is increasing significantly. Waste and recycling of disposable cups have become a social concern for Koreans and Korea implemented the "Disposable Cup Deposit Systems" again in December 2022. Whether the emergence of this system can change the way people behave in environmental protection is a question to be examined in this study. Companies participating in the disposable cup deposit system are hoping that customers will actively recover cups through self-service in the process of collecting disposable cups. The government, along with businesses, transfers recovery work to customers through self-service technologies and schemes. Due to the increase in Shadow Work and the strengthening of consumer environmental protection consciousness, this paper focuses on how unmanned service types such as self-service technology can affect people's environmental protection behavior. An empirical analysis with 477 samples examined how the characteristics of shadow work, perceived efficacy, environmental awareness, and ecological guilt affect user's environmental protection behavior. Perceived efficacy that acts as a mediator and ecological guilt that plays as a moderator are investigated. Although there have been many studies on the effects of shadow work on customer behavioral intentions before, it has been very rare to study the effects of shadow work perceived by people on environmental behavioral intentions from an environmental protection perspective. This study shows that the higher the perceived efficacy of consumers, the more people prefer self-service technology and the stronger the environmental protection behavior. Also, consumers' ecological guilt significantly moderates the relationship between environmental consciousness and eco-friendly behavior. It is expected that companies and governments will be able to understand the impact of shadow work on consumers' environmental protection behavior and further promote environmental protection by appropriate policies and marketing strategies.
