It is well known that pipelines have the highest capacity and are the safest and least environmentally disruptive form of transporting oil and gas. However, pipeline damages caused by both internal and external corrosion is a major concern threatening the reliability of oil and gas transportation and the soundness of pipeline structure. In this study, we estimated the expected allowable damage defect by comparing the ASTM B31G code which has been developed as the evaluation method of reliability and incident prevention of damaged pipelines based on the amount of loss due to corrosion and the yield strength of materials to a modified theory considering diverse detailed corrosional forms. Furthermore, we suggested the method that estimates the expected life span of used pipelines by utilizing the reliability method based on major variables such as, the depth and length of damage and corrosional rate affecting the life expectancy of pipelines.

The compositions of residual extractives in woodmeal, unbleached and oxygen-delignified aspen kraft pulps were investigated with gas chromatography(GC) and gas chromatography-mass spectrometry (GC-MS) with focus on fate of extractives in kraft pulping and oxygen delignification. Steryl esters and shorter retention time (shorter than palmitic acid) extractives were main extractives in aspen woodmeal. Shorter retention time extractives were well removed in kraft pulping. Sterol esters were hydrolyzed to sterols and fatty acids. Sterols and fatty acids were two major extractives classes in unbleached kraft pulps. Linoleic acid was main fatty acids in unbleached pulps compared with palmitic acid which is generally found in aspen woodmeal. Sterolsand fatty acids were also two major extractives classes in oxygen-delignified kraft pulps. However, linoleic acid was well removed in oxygen delignification.

We analyze the current quality management status for firms producing steel outfits of ships and develop an efficient QMS appropriate to Korean steel outfit industry. The firms recently obtained ISO 9000 certificates and are located in Pusan ${\cdot}$ Kyungnam district of Korea. The analysis is based on the audit results from ISO 9000 for seven steel outfit firms during last three years. We find out major requirements of ISO 9000 and investigate statistical relationship among major requirements, types of data, and groups of firms by using a statistical package, SAS. Recommendations regarding add-on requirements are suggested to install an efficient QMS in Korean steel outfit firms.

Pollution emissions from international shipping and port activities have a significant impact on public health and global climate changes. The purpose of this paper is to review the status of pollution mitigation measures implemented to date in port industry and find out some implications for Korean ports. For this aim, the clean air strategies of the world major ports including six USA ports (Los Angeles/Long Beach, Now York/New Jersey, and Seattle and Tacoma), two European ports (Rotterdam and Gothenburg) and Busan Port were considered. Various measures to reduce emission from ports are evaluated by sectors-ocean going vessels, cargo handling equipments, truck and rail-, on the basis of categories such as reduction control technologies, operational changes and market-based measures. The policy implications of this paper are as follows. First, Clean Air Act Plans of Korean ports are required as soon as possible. Second, integrated approach is required to reduce emission effectively. Finally, the effect of port-related emission reduction can be maximized when various measures are conducted on a regional basis including neighboring ports. Furthermore, regional or global-based approach is useful to guarantee the level playing field among ports.

In digital marketing, means of public relations and marketing of enterprises are changing into marketing techniques of predictive analytics. A significant study can be carried out by an analysis of 'the patterns of customers' uses' using big data on major portal sites and SNSs and their correlation with related keywords. This study analyzes the origins of mythological characters in major brands such as Nike, Hermes, Versace, Canon and Starbucks. Also, it extracts related keywords and relevance using big data on portal sites and SNS and their correlation. Nike marketing that reminds people of 'the goddess of victory, Nike' formed a good combination of the brand with relevance. Most of them are based on Greek mythology and have rich materials for storytelling and artistic values in common. Hopefully, this case analysis of foreign brands would become a starting point of discovering the materials of the domestic mythological characters.

The inorganic compositions of traditional lye, and lyes prepared from the stalks of five different agricultural products: beans, wheat, barley, buckwheat and red peppers, were analyzed. Traditional lye was composed mainly of a weak alkaline salt, potassium carbonate as the major component and neutral salts, potassium chloride and potassium sulfate as minor components. The ash and lye contents of buckwheat have significantly higher then those of the rest agricultgural products. Bean and red pepper stalks lyes were composed mainly of potassium carbonate, similar to the composition of traditional lye, but also contained potassium chloride or sulfate. In contrast, postassium chloride was the major component of wheat and barley stalk lye.

Since Component-Based Development, or CBD, struck Korea SI industry a heavy blow several years ago, many major SI companies in Korea have implemented the CBD practices in real world, leveraging supports from the government and academic world. The result, however, falls short of their expectations. The major reason is that they have mainly focused on CBD processes and technical issues around it, although it is necessary as well to deal with other non-technical issues in order to make business values from CBD. This paper begins with reminding us what CBD tries to achieve indeed in terms of software development processes, then recognizes what we have achieved so far introducing a recent CBD project case, BOK-WIRE system. Thereafter, it reveals the chances that SI companies must take in order to make their CBD efforts succeed, pointing out what are the roadblocks really.

Deregulation is not a matter or problem to be resolved simply by revising a law or a system in a short period of time. Rather, it should be implemented at a steady pace on the basis of a full understanding of the relationships between government regulation and the government's role, taking into account the inherent functions of the market. Moreover, arguments about government regulation and its deregulation vary according to viewpoints and approaches on the part of parties concerned. This makes it more difficult to form a consensus or reach a conclusion in recognizing and resolving the basis of problems at issue. This paper aims to review the shipping industry deregulation of major countries, to analyze Korea's situation and problems of shipping regulation, and to suggest it's improving methods. Although government regulation is a sensitive policy issue, this paper remains relatively at the basic research. Regulation problems should be tackled by interdisciplinary approach. A specific approach in regulation study could not explain exactly the causes and results of government policy

This study analyzed the curricula of fashion related majors at 4-year colleges in the USA, UK, Japan and Hong Kong as well as in Korea and compared the characteristics of the Korean curriculum with those of the four countries. A total of 124 curricula from 103 colleges were collected. Courses were divided into eight categories (including industry and market information; materials; merchandise planning; design; production; distribution and selling; basics; and consumption) representing the production and distribution process of fashion business. There were differences in course offerings among the five countries. Overall, curricula in Korea emphasized design and production (construction) areas and showed not much differentiation among colleges. While industry and market information, merchandise planning, and production (management) areas were emphasized in the USA , differentiation/specialization by major was observed . UK and Hong Kong had well-specialized curricula by major Japan seemed to offer traditional and consumption oriented courses. Based on the findings, some propositions for the Korean fashion curriculum were discussed.
