Software requirements written in natural language may have different meanings from the stakeholders' viewpoint. When designing an architecture based on quality attributes, it is necessary to accurately classify quality attribute requirements because the efficient design is possible only when appropriate architectural tactics for each quality attribute are selected. As a result, although many natural language processing models have been studied for the classification of requirements, which is a high-cost task, few topics improve classification performance with the imbalanced quality attribute datasets. In this study, we first show that the classification model can automatically classify the Korean requirement dataset through experiments. Based on these results, we explain that data augmentation through EDA(Easy Data Augmentation) techniques and undersampling strategies can improve the imbalance of quality attribute datasets, and show that they are effective in classifying requirements. The results improved by 5.24%p on F1-score, indicating that handling imbalanced data helps classify Korean requirements of classification models. Furthermore, detailed experiments of EDA illustrate operations that help improve classification performance.

Recent IT (information technology) environmental changes, such as emerging social network services or increasing user participation in multimedia environment, have made it necessary for e-learning systems to undergo changes in various ways. Metadata is an agreement for interoperability between different systems. The standardization of metadata for e-learning system has been driven by some domestic and international organizations, but applying diverse environmental changes into the design of e-learning metadata is in dire need. In this paper, we present a methodology for the analysis and design of modeling e-learning metadata and elicit the design requirements, on the basis of the metadata standard KEM 3.0, about the elements that are expected to be needed in future e-learning systems. Based on the requirements from the analysis, we present the three-layer model for classifying the requirements by the importance of metadata elements per Kana Model. An intelligent e-learning system is to be developed based on the proposed modeling design, which we hope to influence the development of an international standard in the future.

Purpose With the increasing number of foreign travelers visiting Korea, it is a heavy question to evaluate service quality of typical domestic hotel companies. Our research aims to evaluate service quality of domestic hotels in Korea from the perspective of foreign travelers in order to provide the quality improvements that call attention for the hotel management. Design/Methodology/Approach In this paper, topics of sentiment followed Lodging Quality Index(LQI) dimensions classifying lodging service quality appropriately. Also, we employed word2vec algorithm which calculates similarity and affinity among the vocabularies accurately. To calculate sentiment of each dimension, we adopted scores from SentiWordNet. Findings From the result, we found the number of foreign travelers particularly satisfied with cleanliness, politeness, and problem solving skills. In contrast, it has also been found out that both promptness of services and efficiency of communication do not fulfill the requirements of travelers.

Today, customer-requirements are getting various, so manufacturing companies face many problems to reflect them with its' new product development or product variety. As the product model managed by companies is more increasing, there might be much more selection conditions and many kinds of parts requited for it. With those reasons, it demands many different kinds of BOM information for new product development and product variety. Under the those manufacturing environment, we can realize that lots of current products have shared many design property and common parts with those of old version. This thesis present these new products for common characteries are classified design property and common parts with those of old version. with product family and it define with modelling language which is Generic BOM. The suggested prototype programmed with Power Builder 6.0 and Ms-SQL is to help companies manage common parts and develop new product effectively by classifying product family's basic characteries with basic and changable levels.

Due to the large size and high complexity of modern buildings, the interest and the studies about indoor spatial information are increasing. Previous studies related to indoor spatial information were mostly about relevant technologies, and the application of indoor spatial information has been less studied. In the present study, the public administrative work areas where indoor spatial information may be applied were identified by using a modified delphi technique. And the indoor LOD (Level of Detail) and indoor positioning accuracy for indoor spatial information applications considering user requirements was established as standards for efficiently establishing and providing services. The required LOD and positioning accuracy for services was established by reestablishing indoor LOD and positioning accuracy and classifying services with reference to those. The indoor LOD was reestablished from LOD 0 to 4 by focusing on service utilization and general recognition, and the positioning accuracy was reestablished in three levels by considering the accuracy of the present positioning technology and service utilization status.

The park in city, is more than just ecological function, contributes emotional refinement and psychological stability to citizens, and give satisfaction of social and recreational activities to the citizens. And it is the place of leisure and the place to raise up the quality of urban environment. Especially, the neighborhood park among urban parks occupies the most important position as a leisure space for local resident, but it can not perform its purpose and function as a leisure space, due to its too formal and insufficient facilities. This study, approaching from point of physical method, intends to make types through classifying each parks by built-type and installed facilities which affect human-beings, approaching from point of human-beings, intends to make the using-type analysis of park-users, and the questionnaire.By grasping of their requirements regarding to the characters and facilities what they want, willing to present the fundamental data for effective utility-activating method of small-scaled neighborhood park.

Purpose - This paper examines whether the imposition of countervailing duties by the United States on undervalued foreign currency is legally consistent with the WTO's SCM Agreement. Design/methodology - The study uses a methodology that involves analyzing relevant WTO agreements, prior panel reports, Appellate Body decisions, and other legal documents. Findings - The findings suggest that to impose countervailing duties, certain legal requirements must be met, including financial contribution, benefit, and specificity. The paper also notes that when calculating the benefits of undervalued foreign currency, losses from import activities due to currency undervaluation must be considered. Additionally, classifying all exports to the US under specific industries or business groups is likely to be inconsistent with the SCM Agreement. Originality/value - Even the US countervailing measures on exchange rate subsidies may not comply with WTO regulations due to incorrect calculation of benefits and a lack of specificity, however, it suggests that when intervening in the foreign exchange market, the measures should aim to achieve only minimum policy goals.

In the GORRAM, the estimation of resource requirements for wartime equipment is based on the ELCON of the USA. The number of vulnerability groups of ELCON are 22, but unfortunately it is hard to determine how the 22 groups are classified. Thus, in this research we collected 505 types of basic items used in wartime and classified those items into new vulnerability groups using AHP and cluster analysis methods. We selected 11 variables through AHP to classify those items with cluster analysis. Next, we decided the number of vulnerability groups through hierarchical clustering and then we classified 505 types of basic items into the new vulnerability groups through K-means clustering.This paper presents new vulnerability groups of 505 types of basic items fitted to Korean weapon systems. Furthermore, our approach can be applied to a new weapon system which needs to be classified into a vulnerability group. We believe that our approach will provide practitioners in the military with a reliable and rational method for classifying wartime equipment and thus consequentially predict the exact estimation of resource requirements in wartime.

The aquatic disease inspector is not classified as an occupation in the current Korean Standard Classification of Occupations(KSCO). Therefore, the roll of the aquatic disease inspector in the medical treatment and the prevention against the aquatic organism disease is underestimated. The aquatic disease inspector is in a more disadvantageous position than the pharmacist and the veterinarian. The purpose of this study is to approve the aquatic disease inspector as an occupation in KSCO. The important contents of this study are as follows. In the first place, this study looks around the general requirements of classifying the occupations in KSCO. The aquatic disease inspector satisfies the most general requirements. But, because of the similarities of job between the aquatic disease inspector and the veterinarian, the aquatic disease inspector do not satisfy the requirement for 'the principle of exclusiveness'. In the second place, this study looks around the classification system of KSCO. The classification system of KSCO is consists of multi steps. This study makes the plan for the appropriate occupation classification of the aquatic disease inspector. In the third place, this study looks for the legal methods to classify the aquatic disease inspector as an occupation in KSCO. In order to classify the aquatic disease inspector as an occupation in KSCO, many regulations of the laws about the aquatic disease inspector and the veterinarian are to be amended and the number of the aquatic disease inspectors is to be increased by the innovative measures.
