The semiconductor industry has continuously been looking for the ways to improve yield and to reduce manufacturing cost. The layout modification approach, one of yield enhancement techniques, is applicable to all design styles, but it does not require any additional resources in terms of silicon area. The layout modification method for yield enhancement consists of making local variations in the layout of some layers in such a way that the critical area, and consequently the sensitivity of the layer to point defects, is reduced. Chen and Koren (1995) proposed a greedy algorithm that removes defect sensitive area using via moving, but it is easy to fall into a local minimum. In this paper, we present a via moving algorithm using simulated annealing and enhance yield by diminishing defect sensitive area. As a result, we could decrease the defect sensitive area effectively compared to the greedy algorithm presented by Chen and Koren. We expect that the proposed algorithm can make significant contributions on company profit through yield enhancement.

This study is intended to analyse the economic sensitivity of imported fishery products due to decrease in or elimination of tariff rates through the progress of free trade. Forty-seven species of fishes were selected for this study on the basis of the HS Code. The substitution and price effects were calculated using the price elasticities of both domestic and imported demands for fishery products under the assumption of 5% decrease in a tariff rate. Seven main economic variables were extracted from the fishery industry which can mediate the substitution and price effects. A multiple regression analysis was conducted to obtain the influence weights of these main economic variables on both effects. The order of sensitivity of the fishes was calculated using these weights. The 47 fish species were classified into four groups according to their sensitivity based on the means and the standard deviations of their total scores on seven main economic considerations. Nine fish species such as squids, hair tails, shellfishes, and crabs belonged to the hyper-sensitive group, whereas 15 fishes such as eels, sea breams, and sea weeds belonged to the sensitive group. Twelve species including common sea basses, cods, and abalones were among the less-sensitive group, and 11 species including skate rays and mud fishes comprised the non-sensitive group.

In this paper we explore the susceptibility of common sensitive loads by voltage sags of power distribution systems. The experimental approach was used for obtaining the susceptibility of single-phase loads and the three-phase induction motor. The experimental result of single-phase loads was transformed to the ITIC(Information of Technology Industry Council) format and used for evaluating the adverse impacts of a individual and repetitive sags using the performance contour of the foreign standard data. In order to assess the impact of voltage sags on three-phase induction motor, also, the experiment was peformed. The experiment was focused on the current, torque, and speed loss of the motor during a voltage sag. For comparing the impacts of individual and repetitive voltage sags, the variations of motor torque is focused among the experimental results. The sensitive curves of instantaneous current peak are used to describe the susceptibility of three-phase induction motor and 진so it were used for the quantitative analysis of the impact of three-phase induction motor due to voltage sags. Through the results of experiment, we verified that some types loads have more severe impact at repetitive voltage sags than individual ones and proposed method can be effectively used to evaluate the actual impact of voltage sags.

This study measures the internal and external competitiveness of 35 OECD countries in the insurance industry. We analyze whether variables related to the Fourth Industrial Revolution affect international competitiveness by applying a nonlinear autoregressive distributed lag model. As a result, the competitiveness of life insurance foreign companies in internal is showing positive responses in high income inequality countries. In addition, insurance companies in countries with low income inequality have shown high performance in external. The non-life insurance industry is less sensitive to shocks than life insurance. This is because non-life insurance is a more dangerous industry than life insurance and there are many restrictions on policies and regulations. The reason is that non-life insurance is a more dangerous industry than life insurance and there are many restrictions on policies and regulations.

Service industry can be divided largely into commercial industry, banking industry, insurance industry, advertising industry, and tourism industry. Of these, banking industry is playing an essential role as it constitutes the backbone of economy. Banking industry, which belongs to financial industry, is sensitive to external environment. In this kind of industry, internal dynamics of an organization is very important. The purpose of this research is to find out what kind of influence the relation of internal dynamics perceived by members of Nonghyup organization has on customer orientation via quality of internal service. For the purpose, we have reviewed preceding studies on variables that affect customer orientation and developed a measuring tool in a form that fits banking organizations. Internal service quality, job satisfaction, and organizational immersion which play a mediating role in the model of this research not only turned out to have a significant influence on customer orientation, they also turned out to have the strongest influence. This research has academic significance as it carried out a research with an emphasis on variables that affect customer orientation of members of Nonghyup organization. Regarding practical significance, it was intended to present useful data that can be utilized for an analysis of internal service quality management and capability of human resource management.

In the era of the 4th industrial revolution, the big data industry is gathering attention for new business models in the public and private sectors by utilizing various information collected through the internet and mobile. However, although the big data integration and analysis are performed with de-identification techniques, there is still a risk that personal privacy can be exposed. Recently, there are many studies to invent effective methods to maintain the value of data without disclosing personal information. In this paper, a personal information protection system is investigated to boost big data utilization in industrial sectors, such as healthcare and agriculture. The criteria for evaluating the de-identification adequacy of personal information and the protection scope of personal information should be differently applied for each industry. In the field of personal sensitive information-oriented healthcare sector, the minimum value of k-anonymity should be set to 5 or more, which is the average value of other industrial sectors. In agricultural sector, it suggests the inclusion of companion dogs or farmland information as sensitive information. Also, it is desirable to apply the demonstration steps to each region-specific industry.

This paper addresses the analysis of interruption costs and the studies made through the direct interview with Korean Industrial customers for the period of two years. It is conducted to evaluate the direct and short duration interruption costs resulting from local random electrical supply interruptions. The cost is evaluated by providing a designed questionnaire focused on the experience or the preparative actions which consumers predicted they would take. In the first phase, authors made a survey on all types of industry with 176 industrial customers and evaluated them as per standard industry classification (SIC). In that case, the evaluation data obtained are not so reasonable, because the number of sampled industries was small and the sampled industries were surveyed by being divided into 18 types. So, in the second phase the authors concentrated on only 4 types of 302 industries who have many and large sensitive loads to the short duration interruption.

Construction Management(CM) has been introduced in Korean Construction Industry for its merits and benefits proven in International Construction Industries. However, many regulations, standards, manuals and details of practices considering its constituents and industry conditions have not yet to be developed. Of these, the standards and details of CM fee calculation should be developed in order to stretch its application toward public construction sectors as well as the private sectors. This research proposes CMFM(Construction Management Fee Model), a project sensitive matric CM fee model for CM fee calculation. The model calculates CM fees for modular services in a two by two matrix taking project phases on one dimension and CM services on the other.

Contemporary young men are consumption-oriented, pursue ideal male images displayed in commercials, and are highly interested in fashion, beauty, and appearance. This metrosexual tendency(which values appearance) is largely influenced by mass media. This study examines how men's media information utilization influences appearance awareness and metrosexual tendency as well as how these two variables influence cosmetics consumption and fashion product consumption behavior. The results are as follows. First, metrosexual tendency consists of four dimensions: fashion involvement, pursuit of individuality beyond sexuality, cognition of fashion taste, and preference of a high quality product. The sum of variance is 65.594%. Second, media information utilization influenced metrosexual tendency and metrosexual tendency influence cosmetic consumption, brand-sensitive consumption and commercial-sensitive consumption; however, it did not affect price-sensitive consumption. Third, media information utilization affected appearance awareness; however, appearance awareness did not affect metrosexual tendency. In conclusion, appearance management behavior for men in their 20s is clearly affected by media. This phenomenon is caused by the metrosexual desire to express identity through fashion. Men in their 20's do not take care of their looks because of the social perception of appearance (as related to showing off their competence or pursuit of social success); rather, they have a desire to express their individuality and personally enjoy grooming and maintaining their appearance. Therefore, we can expect increased beauty and fashion expenditures.
