This study was carried out in order to develop brand and packing design for agricultural products of Dangjin County. Current packing designs such as rice packs, cucumber box, sweet potato box, apple box and kimchi pack were collected from agricultural cooperatives in Dangjin area. For those packing designs, corporate identity(CI) clinic was conducted and the results obtained were as follows: There are varieties of names, colors, fonts, and sizes far the same items, so that consumers could not easily find and understand those CIs of agricultural products in Dangjin County. Among others, those packages are needed CI clinic such as the packages of Dangjin apple(Song-ak Agricultural Cooperative), Dangjin sweet potato(Seok-moon A. C.) and rice(Daehoji A. C., Shinpyeong A. C.). However, the packing design of Hyang-chae-bang Kimchi is evaluated as good design. For CI clinic, it is desirable to develop unique and united brand name and simple design for the packages such as the case of 'Anseong-Matzum' of Anseong City, which is unique and united brand name with simple design enhancing synergy effect for agricultural marketing.

In this study, the optimal design of the multi-cavity mold layout and packing pressure for the automobile TCU connector cover is determined based on the injection molding analysis and the desirability function method for multi-characteristic optimization. The design characteristics to be optimized are the warpage and sink marks of the product, the scrap of the feed system, and the clamping force. The optimal design is determined by performing injection molding analysis and desirability analysis for design alternatives defined by a complete combination of five mold layouts and six-level packing pressure. The optimal design shows that the desirability values for individual characteristics are quite high and balanced, and the resulting values of individual characteristics are satisfactorily low.

This paper introduces the mix design and performance evaluation of Ultra-High Performance Concrete (UHPC). The concrete mixture is designed to achieve a densely compacted cementitious matrix via the modified Andreasen & Andersen particle packing model. The compressive strengths of UHPC designed by this method reached 154MPa. The relationship between packing theory and compressive strength of UHPC is discussed in this paper.

In this paper, we proposed an automatic packing mechanism of one station concept for fastener objects where the continuous work is performed in a finite space. The proposed packing mechanism is composed of supporting frame, feeding supply, air shower device, clamping/opening device, batch charging device, sealing/cutting device and supply adjusting device. And, these mechanisms have been modularized through mechanical, dynamical, structural and fluid optimized design using the SMO(SimDesigner Motion) analysis module. Also, the virtual prototype was carried out using the 3-D CAD program. The packing process is consisted performed in the order of feeding, clamping, bottom sealing, cutting, opening, object charging, closing and the upper sealing. And the time of these cycles were designed to be completed in 15-20 seconds. This packing mechanism will be created as a prototype in the near future. In addition, it will be applied to the production scenes after going through a field test for the validation of performance.

In this country, mackerel landing, sorting, and packing are mostly performed manually, which is time consuming and labor intensive. An unloading automation system saves time and labor by automating the landing, sorting, and packing processes. Casers are devices for manufacturing packing boxes for fish used by unloading automation systems. The caser design in this study is for mackerel packing boxes. This caser makes a packing box based on a press using the caser's slide crank. When the caser makes a packing box, the manufacturing sequence is determined by the caser's production guide and assisting rod. The caser design in this study is simulated using a multi-body dynamics program. The simulation is used to analyze the caser and to visualize the box-making sequence.

The study was carried out to demonstrate the superiority of used packing in view of energy saving and efficiency of mass transfer, comparing with conventional packing. The results are as follows : 1. Owing to low Pressure drop under high load. 25mm NSW-ring, pp. can cause energy saving 2. The unique magnitudes of used packing are as follows $C_G$=5.78, m=0.67, n=0.46 3. Used packing can make high efficiency including energy saving because of low pres sure drop per the number of transfer unit. To rate the characteristic of packing, It should be carried out that the measurement of pressure drop per packing height and per the number of transfer unfit. This study demonstrated the superiority of used packing by carring out above experiment and could be used as basic reference for design and predicting efficiency of packing tower which is tilled with same packing.

알루미나 파우더는 산업용으로 널리 사용되는 소재 중 하나이지만 파우더 패킹 상태에 따라 제품의 강도가 변하는 문제점이 있다. 위 문제해결을 위하여 입자 패킹효율을 높이려는 많은 선행연구들이 수행되었지만, 기존 연구는 밀리미터 스케일의 입자의 충진 특성을 분석한 것이 대부분이므로 마이크로미터 스케일과 물리적 특성이 달라, 그 선행연구 결과를 토대로 마이크로미터 스케일에 적용하기 어렵다. 따라서 본 논문에서는 마이크로미터 스케일의 알루미나 파우더를 이용하여 충진률을 높이기 위하여 통계적방법을 이용하여 3단계 실험을 수행하였다. 먼저, 혼합물시험계획법을 이용하여 충진율이 높은 크기 조합 및 혼합 비율을 선정하였으며, 진동 실험장치에서 가진 주파수 변경에 따른 충진 높이 변화를 분석하여 적정 가진 주파수를 선정하였다. 마지막으로 앞서 언급한 실험 결과값을 토대로 알루미나 파우더 충진율 시험을 수행하였다. 그 결과, 최대 높이 변화량은 충진 크기조합 선정을 위해 수행한 최초의 실험 결과 최댓값보다 42% 향상된 것을 확인하였다.

광고매체, 대형할인마트 등에서 소비자의 눈길을 끌기 위해서는 경쟁력 있고 차별화 된 포장디자인을 통한 강력한 브랜드의 이미지가 요구된다. 본 연구에서는 소비자의 브랜드에 대한 긍정적인 태도를 유출하기 위해서 포장디자인의 중요성을 깨닫고 시각적인 측면에서 과실음료 포장디자인의 표현방법에 따른 소비자의 선호도를 연구하였다. 연구결과 음료의 포장디자인에서 원재료를 사실적인 방법으로 표현하였을 경우 비사실적 표현방법보다 소비자가 느끼는 과즙 함유량이 높게 나타났다. 웰빙(Well-being)의 관심도와 원재료의 포장디자인에서 표현방법에 따른 소비자 브랜드 선호도에서는 웰빙(Well-being)에 관심이 많은 사람이 사실적 표현방법을 선호하는 것으로 나타나 통계적으로 유의한 차이가 나타났다. 소비자가 가장 선호하는 음료의 용기재질로는 유리병으로 나타났으며, 가장 선호하는 오렌지 주스의 종류는 100%과즙함유로 나타났다. 따라서, 웰빙(Well-being)의 관심도와 음료의 원재료에 대한 표현방법은 브랜드 선호도와 구매의도에 차이를 보이는 것으로 나타났으며 과즙의 함유량에도 영향을 미치는 것으로 나타났다.

Optimum packing of aggregate is an important aspect of mixture design, since porosity may be reduced and strength improved. It may also cause a reduction in paste content and is thus of economic relevance too. Several mathematic packing models have been developed in the literature for optimization of mixture design. However in this study, numerical simulation will be used as the main tool for this purpose. A basic, simple theoretical model is used for approximate assessment of mixture optimization. Calculation and simulation will start from a bimodal mixture that is based on the mono-sized packing experiences. Tri-modal and multi-sized particle packing will then be discussed to find the optimum mixture. This study will demonstrate that computer simulation is a good alternative for mixture design and optimization when appropriate particle shapes are selected. Although primarily focusing on aggregate, optimization of blends of Portland cement and mineral admixtures could basically be approached in a similar way.
