신선 농산물의 필름포장은 적정의 저온저장 시에는 적정 변형기체조건 유지로 품질유지가 양호하나, 상대적으로 온도가 높은 판매유통단계에서는 적정조건의 유지가 어려워 품질손실이 발생한다. 저온저장과 판매유통단계에서 농산물 주위에 적정 변형기체(modified atmosphere, MA)조성을 유지하는 개별(1차)포장/2차 포장의 결합 및 해체 개념을 설계한 마스터 포장 시스템이 최근에 제안되고, 단감, 큰느타리 버섯, 밤, 딸기에 대해서 적용된 바 있다. 온도에 따라 다른 농산물의 호흡과 포장의 기체이동 현상의 상호관계를 이용한 마스터 포장 시스템의 개념을 체계화하고, 적정 MA 유지를 위한 설계변수의 조합을 살펴보았다. 바람직한 포장기체조성을 형성 유지할 수 있는 마스터 포장 시스템의 설계를 위한 수학적 모델이 제시되었다. 아울러 마스터 포장 시스템의 이점과 함께 적용을 위한 한계에 대해서 논의하였다. 마스터 포장 시스템의 적용 확대를 위한 미래의 연구방향을 제시하였다.

Various automatic temperature control systems have been used widely in Korea for the conservation of heating energy and the enhancement of thermal comfort in residential buildings. But the heating control performance for automatic temperature control systems extensively vary with the design and operational conditions of the heating system, the climate condition and others. It was introduced in this study a numerical calculation program package to analyze heating control characteristics of the automatic temperature control system. This package is able to analyze the room air temperature, return water temperature, supplied heating flux and flow rate, and so on. One the other hand, the simulation results were verified by comparing with the field test results.

The electrical performance of a package is extremely important for high speed digital system operations. CSP(chip scale package) is known to have better electrical performance than the convnetional packages. In this paper, the electrical performance of the BLP(bottom leaded plastic) package, a kind of CSP, has been alayzed by both simulation and real measurement. The electrical perfdormance of a BLP was compared with that of the conventioanl TSOP(thin small outline package). The leadinductanceand lead capacitance were used for the comparison purposes. The new BLP design provides much better electrical performance that TSOP package. It has about 40% favorable parameter values.

High-resolution satellite image processing software should be able to ensure accurate, fast, compact data processing in offline or online environment. In this paper, component software for high-resolution satellite image processing is developed using OpenGIS components and real-time data processing architecture. The developed component software is composed of three major packages, which are data provide package, user interface package, and fast data processing package. The data provider package encodes and decodes diverse image/vector data formats and give identical data access methods to developers. The user interface package supports menus, toolbars, dialogs, and events to use easier. The fast data processing package follows the OpenGIS's data processing standards, which can deal with several processors as components with standard procedural functionalities.

This study investigated the influence of package design of female cosmetics on the purchasing preferences of view The subjects of this study were the consumers of female cosmetics from their twenties to the forties, and were 195 consumers who dropped into beauty counters to buy their cosmetics. With this study, it can be said that package design Is an effective factor on purchasing of female cosmetics. In general, most consumers prefer to practical and useful package design. But the younger consumers tend to be more influenced by luxury and expensive package design than an elderly consumers on purchasing cosmetics. And it made a little difference in purchasing preferences by academic background.

In this paper, high speed IC package-to-package interconnections are modeled as lossless multiconductor transmission lines operating in the TEM mode. And, three mathematical algorithms for computing electrical parameters of the lossless multiconductor transmission lines are described. A semi-analytic Green's function method is used in computing per unit length capacitance and inductance matrices, a matrix square root algorithm based on the QR algorithm is used in computing a characteristic impedance matrix, and a matrix algorithm based on the theory of M-matrix is used in computing a diagonally matched load impedance matrix. These algorithms are implemented in a computer program DIME (DIagonally Matched Load Impedance Extractor) which computes electrical parameters of the lossless multiconductor transmission lines. Also, to illustrate the concept of design database for high speed IC package-to-package interconnection, a database for the multi conductor strip transmission lines system is constructed. This database is constructed with a sufficiently small number of nodes using the multi-dimensional cubic spline interpolation algorithm. The maximum interpolation error for diagonally matched load impedance matrix extraction from the database is 1.3 %.

The generation of small hydropower as compared to other different developed environmental methods produces one of the clean energies. In such manner, various application system development through IT technique is being developed for an advanced small hydropower energy resources data mining. However, existing data analysis of New & Renewable Information System for small hydropower resources application is incomplete therefore it limits expressing these information on the Web. Thus for positive usage of small hydropower resources, a more systematic and precise analysis system should be built. This study seeks to develop a map of the domestic small hydropower resources problems to further improve small hydropower resources, developed through Package Tool which can accurately evaluate a wide range of small hydropower basin in a short period of time. Small hydropower Package Tool was calculated using existing Analysis System small hydropower resources which did not provide diverse capabilities resulting to 840 standard basin classified by A and facility capacity, etc., and to assume a 40% annual capacity, expected annual electricity production was calculated. Small hydropower for the national water system of small hydropower resources potential calculated in terms of resources for the development of small hydropower will be utilized as basic data.
