해양 분야에서는 최근 e-Navigation의 실현을 위해 국제수로기구의 S-100을 기반으로 다양한 해양 데이터 및 관련 데이터의 통합, 활용에 관한 표준 연구가 활발히 이루어지고 있다. 그리고 S-100을 기반으로 전자해도, 심해지형 등 해양 데이터를 제작, 배포하는 S-100 기반 product specification이 개발되고 있다. e-Navigation 환경에서 다양한 데이터를 통합, 활용하려면 해당 데이터들이 S-100 기반의 product specification에 따라 제작, 배포해야 한다. 본 연구에서는 안전 항해의 중요한 요소인 항로표지 정보를 S-100 기반의 시스템에서 통합, 활용할 수 있도록, 항로표지 데이터를 제작, 배포하는 가이드라인에 해당하는 항로표지 product specification을 개발하였다.

The objective of this paper is to examine the country of origin effect of products made in the Republic of Korea. The study focuses on the questions of the sources of information in evaluating products; the evaluation of specific product dimensions by Malaysian consumers; and consumers' assessment of different product categories. It reports on the findings of a survey conducted in which 244 responses were obtained. The most common product information source was found to be through advertisements in television and radio.. Products made in Korea had been rated highly for its product style. Consumer electronics were generally found to be the popular preference of product category by Malaysian consumers. The managerial implications of our study are discussed and the limitations of the study are also examined.

Generally, the assembly system relied on conveyor lines is efficient for mass production. But it is not efficient when the product types are often varying and their lot sizes are small. Especially, it is much inefficient for the assembly lines for the electronic products whose types are varying very often. This paper suggests the design of U-shaped assembly lines to replace the existing conveyor systems. The assembly line for the mini-cassette production is dealt with as a case study. The proposed procedure was successfully applied for the design of U-shaped lines. The developed method resulted in the improvement of the productivity such as the decrease of the man power and the cycle time, and the increase of the line utility.

The purpose of this study is to investigate the manufacturing technique on the U type Draw-Bending of inner grooved tube. This bending process make the U shape tube by Hair Pin Bending machine. The U type tube requires the quality of product that satisfy sufficient conditions for a heat exchanger. The mandrel components act the important roles that prevent wrinkles and keep the shape of cross section of bended tube at bending process. We performed the FEM simulation using LS-DYNA software and the bending test of inner groove tube and then, compared bending simulation with bending test results about mandrel ball diameter, mandrel position and optimal clearance between mandrel and tube.

The study attempts to investigate the causes of Sino-U.S. trade friction in recent years and provides countermeasures accordingly. The import and export volume of two countries, the product structure of China's export, the 337th Act lawsuits related to China, the industries involved in trade friction, and the G-L Index of Sino-U.S. Products are analyzed in detail. The causes of Sino-US trade frictions are discussed from the aspect of mercantilism and trade protectionism, interest groups and governments' trade policies, Chinese product structure, intellectual property protection in China, and performance of Chinese enterprises in litigation. Based on these, countermeasures are put forward. China needs to implement industrial upgrading, increasing the added value of products, and improving intellectual property protection. A trade friction warning system also needs to be constructed. The Chinese government needs to carry out strategic dialogue and international negotiation.

Semantic Web and its related technologies have been opening the era of information sharing via Web. In the meantime, there are several huddles to overcome toward the new era and one of the major huddles is information integration issue unless we build and use a single unified but huge ontology which address everything in the world. Particularly in e-business area, information integration problem must be a great concern in search and comparison of products from various internet shopping sites and e-marketplaces. To overcome such an information integration problem, we propose an ontology driven mapping algorithm between heterogeneous product classification and description frameworks. We also perform comparative evaluation of the proposed mapping algorithm against a well-known ontology mapping tool, PROMPT.

In [25] Taskinen shows that if $\{E_n\}_n\;and\;\{F_n\}_n$ are two sequences of Frechet spaces such that ($E_m,\;F_n$) has the BB-property for all m and n then (${\Pi}_m\;E_m,\;{\Pi}_n\;F_n$) also has the ΒΒ-property. Here we investigate when this result extends to (i) arbitrary products of Frechet spaces, (ii) countable products of DFN spaces, (iii) countable direct sums of Frechet nuclear spaces. We also look at topologies properties of ($H(U),\;\tau$) for U balanced open in a product of Frechet spaces and $\tau\;=\;{\tau}_o,\;{\tau}_{\omega}\;or\;{\tau}_{\delta}$.

In this paper, we deal with random attractors for dynamical systems forced by a deterministic noise. These kind of systems are modeled as skew products where the dynamics of the forcing process are described by the base transformation. Here, we consider skew products over the Bernoulli shift with the unit interval fiber. We study the geometric structure of maximal attractors, the orbit stability and stability of mixing of these skew products under random perturbations of the fiber maps. We show that there exists an open set U in the space of such skew products so that any skew product belonging to this set admits an attractor which is either a continuous invariant graph or a bony graph attractor. These skew products have negative fiber Lyapunov exponents and their fiber maps are non-uniformly contracting, hence the non-uniform contraction rates are measured by Lyapnnov exponents. Furthermore, each skew product of U admits an invariant ergodic measure whose support is contained in that attractor. Additionally, we show that the invariant measure for the perturbed system is continuous in the Hutchinson metric.

This paper researched on countries effect of country-of origin product of the Korea customer. Also This study was analysis to purchase frequency and purchase place for products of the U.S.A, Japan, China, EU, and Chile in Korea market. That is to say, this study is reviewing on country image subject including country of origin. According to WTO rule, The rules of origin should be administered in a consistent, uniform, impartial and reasonable manner. The objective of this article is to explore the relationship between country of origin and consumer effect using empirical analysis. The country of origin was divided into country of design, assembly, and parts. A survey questionnaire was sent to 250 customer in Korea market, and 220 usable responses were obtained. The 213 samples are analyzed with the countries origin effect. Multiple regression results show that the U.S.A and Japan product are positively affected by the purchase effectiveness of Korea customer's. However, The EU, China and Chile products do not affect effectiveness in Korea market. This article contributes to a understanding of effects of country-or-origin. When the nation image has been made, marketing approaches considering both image of country of manufacture origin and motivational focus can be utilized simultaneously.

Based on 11 Classics of Materia Medica designated by Ministry of health and welfare bulletin 1995-15 as legal basis in scope and preparation of herbal prescription, we reviewed indication, property and processing of Rhus Verniciflua Stokes which appear extensively in literature since earlier Joseon Dynasty. Following is the conclusion of this review after comparing with 'Korean Pharmacopoeia: commentary on herbal product standard'. 1. The properties of Rhus Verniciflua Stokes in 'Korean Pharmacopoeia :commentary on herbal product standard' should be changed as 'Tonifying the middle, restoring the muscle, fulfilling marrow, breaking old static blood, tonifying and activating after removing mass, unblocking the meridian, killing worms' and indication should be changed as 'Old static blood, deep rooted mass, wind-cold-dampness arthralgia, cough, 9 types of chest pain, abdominal or flank accumulation of stagnated qi[氣], amenorrhea, hernia mass, small bowel or bladder colic pain, abdominal pain due to worm accumulation'. 2. The processing of Rhus Verniciflua Stokes in 'Korean Pharmacopoeia: commentary on herbal product standard' should include 'natural drying or steaming drying followed by grinding and stir-baking until ripened or smoking appears'.
