Despite the rapid expansion and diversification of the global ship repair and shipbuilding market, the domestic ship repair and shipbuilding industry is losing competitiveness due to a lack of infrastructure compared to its high technology level, concentration of new markets, aging technology personnel, lack of IT systems, and small businesses. Although attempts have been made to develop information systems at a very low level compared to other industries, there are few successful cases. Therefore, the purpose of this study is to understand the necessity of strategic integration and organizational integration from the perspective of informatization in the ship repair and shipbuilding industry through a survey of companies operating in Busan. After that, through face-to-face interviews with major repair shipyard companies in Busan, the direction of the development of the information system of the ship repair and shipbuilding industry was derived. The results of this study are expected to enhance the need for digital conversion of the ship repair and shipbuilding industry in the future and provide a significant direction for the establishment and application process of information systems.

There were many studies conducted on economical aspects of employment among the elderly in national level, however, very few studies examined social and psychological aspects of senior employment and employment preferences of the elderly persons. The purposes of this study were to examine major determinants of decision making in employment, and to explore some relationships among decision making of employment, socio-economic factors, health and psycho-social factors, and labor and economical factors among non-working elderly persons in the community. In all, two-hundred-twenty elderly persons were interviewed and one-hundred-ninety-four were analyzed in this study. The descriptive statistics, analysis of variance, correlation analysis, and logistic regression were used for the data analysis in this study. The study found that the respondent's sex, ages, education, numbers of children, physical health, ADL, self-efficacy, economical stress, numbers of years in labor, asset of real estate, family allowances, and the benefit levels of pension were major determinants of decision making in employment among non-working elderly persons. Finally, some implications were discussed for developing effective senior employment in national policy, job related services, and welfare programs of the elderly persons for the successful aging.

Purpose : This study attempted to observe the correlation between the activity levels and interpersonal relationships of elderly people. Method : This study implemented the Relationship Change Scale (RCS) and the Korean Activity Card Sort (K-ACS) on elderly people who use community welfare centers in the Busan and Ulsan areas from May 28, 2015 to August 26, 2015. Results : Total ACS scores and sensitivity showed a high correlation with .326. Next, instrumental activities of daily living and sensitivity showed a high correlation of .287, and instrumental activities of daily living and sense of satisfaction showed a high correlation of .277. However, social activities showed no correlation with the subcategories of interpersonal relationships. Conclusion : People who adequately carry out their roles in daily living and enjoy leisure activities showed high scores in interpersonal relationship satisfaction, understandability, sensitivity, and openness. This shows that it is necessary for elderly people to have interest in successful aging such as participation in activities that exceed welfare through simple medical support or interpersonal relationships and in demands related to the quality of life.

Due to the development in industrial technology, changes in consumer behavior and aggravating competition within the industry, it is growing only harder every day to build up a strong brand power. Besides, a brand is supposed to age as time goes by, following a brand life cycle, as it is not a solid, immutable asset but something of a living creature. Therefore, self-renovation and revitalization efforts are needed, in order to incessantly confirm the self existence through the relationship with the consumer. In sum, revitalization operation is needed to renew a brand that has grown trite in the passage of time or due to the change in market condition, so as to bring it back anew to the consumers. This study did not stop at measuring the effect of a design renewal as a short-term assignment, but focused on the long-term brand management following the brand life cycle and aimed to define the effective timing and method of revitalization by comprehending the analysis results of consumer consciousness by analyzing the successful cases of brand revitalization and selecting the research analysis targets. As a result, this study proved that a properly-timed brand revitalization efforts in order to cope in advance with predictable changes in environment, can significantly prevent any drop of brand equity from occurring and then extend the brand life cycle. Also, this study could find that a brand revitalization is not a mere concept of a strategy for a short-term sales increase, but should be a long-term strategy to manage a brand, which must be practiced continuously in the time when the brand life cycle curve starts to fall. This research could also confirm that a superficial design renewal, which changes only the packaging of a brand, peformed in short-term haste, is not of help at all.

Smart work, which is defined as work performed at home, satellite offices or with the smart devices to continually collaborate with the co-workers in anytime, anywhere using IT, is attracting much attention as an alternative work way to cope with the demographical changes of the low fertility and aging. Whereas some implementation cases of smart work have been considered as the success, the other cases have been reported as the failure to implement smart work practices. Nevertheless, there are few researches to identify the reasons of successful ways to adopting smart work. This study integrated the IT-based changes with the smart work practices to identify the critical success factors of smart work in individual, organization and industry levels. As the results, we found out the expected values of introduction, core elements of implementation, and industry characteristics to efficient adoption for smart work. Also, this study compared these evidences with the incumbent smart work policies. The contributions of this study is to develop the guideline to adopting smart work, the smart work implementation strategy and the improvement on the business process.

A successful oil well drilling depends largely on a good mud Program. During drilling, mud provides sufficient hydrostatic pressure, removes drill cuttings and cools drill bits. Mud additives are always required to provide sufficient hydrostatic pressure to ensure borehole stability. Barium Sulphate ($BaSO_4$) also known as barite is the prevalent weighting material but there is needed to develop local materials to augment the use of Barite. The present search is concerned on the early Carboniferous succession exposed in Um Bogma Formation, west central Sinai, Egypt as a new weighting agent in drilling fluids. The increases in the cost of drilling fluids and a shortage of using barite have introduced the locale dolomite as alternative weighting materials. The rheological properties of mud drilling samples weighted by local dolomite samples are being examined and investigated to know its potential to be used as a weighting material in drilling mud. Two mud samples were prepared which comprised of fresh water, caustic soda, bentonite and the weighting material. The weighting materials are added to achieve the required density. The first sample: Water-based mud with commercial barite of density between 10.00 lb/gm and 18.00 lb/gm. The second sample: Water-based mud with dolomite of density between 10.00 lb/gm and 18.00 lb/gm. These samples were analyzed and the density, rheological properties, aging of barite and dolomite and solid contents were investigated. At 10.00 lb/gm, the yield point of dolomite was $20.00lb/100ft^2$ and barite $22.00lb/100ft^2$ while the 10 second gel strength of dolomite was $30.00lb/100ft^2$ and $22.00lb/100ft^2$ for barite. Similarly, little difference was observed in plastic and apparent viscosities. At 10.00 lb/gm, the plastic and apparent viscosities of dolomite were 8.00 cp and 20.00 cp while barite was 8.00 cp and 24.00 cp. The result show that dolomite mud sample gave a little higher yield point and gel strength than barite mud sample. Therefore, dolomite has the potential to be used as weighting material in drilling mud in place of barite thereby enhancing the local content initiative of the government. When dolomite is sourced locally and used it will reduce overall mud and drilling costs.
