Recently, various approaches to recommendation systems have been studied in terms of the quality of recommendation system. A recommender system basically aims to provide personalized recommendations to users for specific items. Most of these systems always recommend the most relevant items of users or items. Traditionally, the evaluation of recommender system quality has focused on the various predictive accuracy metrics of these. However, recommender system must be not only accurate but also useful to users. User satisfaction with recommender systems as an evaluation criterion of recommender system is related not only to how accurately the system recommends but also to how much it supports the user's decision making. In particular, highly serendipitous recommendation would help a user to find a surprising and interesting item. Serendipity in this study is defined as a measure of the extent to which the recommended items are both attractive and surprising to the users. Therefore, this paper proposes an application of serendipity measure to recommender systems to evaluate the performance of recommender systems in terms of recommendation system quality. In this study we define relevant or attractive unexpectedness as serendipity measure for assessing recommendation systems. That is, serendipity measure is evaluated as the measure indicating how the recommender system can find unexpected and useful items for users. Our experimental results show that highly serendipitous recommendation such as item-based collaborative filtering method has better performance than the other recommendations, i.e. user-based collaborative filtering method in terms of recommendation system quality.

Objectives: This study explores the characteristics of family migration for North Korean defectors and classifies family migration by examining who initiated the migration and who followed. Method: We analyzed the family migration using detailed stories from fifty-five North Korean defectors who were interviewed between 2005 and 2011. Results: We found that 43 out of 55 cases were family migration and the remaining 12 cases were single person migration. We also found several characteristics typical of migration. First, family migration followed the process of step migration, which indicated a serial migration in numbers. Second, migration relied heavily on informal social networks. Finally, the process of earlier migration by North Koreans was incidental and unexpected; however, unexpectedness has diminished in recent migration. Looking at who initiated the migration, the most common type was 'mother-initiated' cases (14 cases) followed by 'child-initiated' cases (10 cases). The third most common type was 'mother-child accompanied' cases (7 cases). The migration process was various; however the most common type was when a married woman initiated the family migration process. This is most likely because married women have the responsibility to support families in the informal economy of North Korea. According to the range of family migrated, the most common type was 'nuclear-family only' cases (22 cases) followed by 'maternal extended family migration' cases (12 cases). Conclusions: The findings of this study provide information on the family dynamics of North Korean defectors.

The purpose of this study was to study the beauty-coordination characteristics of Genderless fashion, which is emerging as a new trend by analyzing the trend in the latest collection and classify the resulting expression characteristics of make-up. Methods and scope of the study were based on collections published in the 2020 S/S season and 35 out of 84 designers with design elements were selected to analyze the garments most likely to be genderless. The characteristics of the expression of the genderless derived through this analysis were classified into compromise, androgyny, sensuality, exaggeration, enjoyment, and historicity. Compromise was the highest, and the lowest was for enjoyment of the classifications. The designer's work according to the characteristics of each expression shows that the pieces by Saint Laurent were the highest in compromise, sensuality, and historicity, and the pieces by Maison Margiela were the highest in androgyny while Balenciaga was the highest in exaggeration and enjoyment. Compromise represented a mixture of discord, such as incongruous bonding and coloring of heterogeneous materials, and androgyny led to the use of silhouettes and colors, with sensuality utilizing see-through material and incision lines allowing for physical exposure. Exaggeration intentionally destroyed the existing concept by breaking the overall balance of the human body through the enlargement of certain parts of the body, while enjoyment showed unexpectedness by destroying the line and sides of the garment. Lastly, historicity was analyzed for its retro design that transcends time and space with regional cultural and period characteristics.

This study aimed to contribute to the development of various female fashion designs by reviewing the genderless styles in androgynous trends that have loomed large in women's fashion, as well as through analyzing and organizing the changes in women's fashion that were required in a society in which various values coexist. A literature review was conducted to identify the genderless concepts, through which a total of 1,273 materials were selected from 10 brands of the S/S collections, during the period of 2006~2016. The results were as follows: first, without the juxtaposition of incongruous objects or images and a fixed type of color arrangements, the compromise shown in women's fashion were mostly expressed through various tones and diverse colors, and with the mixed use of heterogeneous patterns and materials. Second, the enjoyment of genderless styles was expressed with the unexpectedness that occur through symmetry/asymmetry and harmony/disharmony, as well as through the deviation from conventional notions regarding clothing structures. Third, the exaggeration expressed in women's clothing collections perfectly covered up a woman's body shape with the silhouette of exorbitantly expanded bulk and dimensions. These were done with extended lengths, expanded adornments, and modified clothing design types or structures. Fourth, the sensuality of genderless styles analyzed in women's fashion was expressed with mannish clothing that accentuates the beauty of the female body. Lastly, the historicity shown in genderless styles was expressed through clothing that represented traditional styles of the past, the symbolic meanings expressed in the clothes' colors and patterns, and the methods in which the decorative factors were utilized.

This research aims to analyze the prep-hop fashion, which is an original look created through the convergence of the hip-hop and preppy look, and identify the design characteristics of the prep-hop fashion. The style mixes the fashion of what was traditionally a lower-class look with the upper class. The design characteristics are as follows: First, the prep-hop fashion expresses slim, casual and sophisticated look with items and silhouettes. The items are categorized into jackets, shirts and pants. The prep-hop jackets provides a casual look to its wearer unlike the jackets of preppy or conservative looks. Slim suits show different meanings and features depending on the changes in the time and culture despite the continued use of the items. Second, the colors of the prep-hop fashion include overall basic colors used in the preppy look and hip-hop fashion. The aesthetic values of the colors express pleasant color images different from the conservative and resistant images expressed in the preppy and hip-hop style before the convergence, respectively. Third, the materials and patterns are expressed in a unique way to fulfill the emotional needs that are considered vital to contemporary fashion. The materials in the prep-hop fashion extend the ranges of usage by using the materials with unexpectedness broken out of general range of usage. While the use of the patterns is one of the methods to demonstrate that the prep-hop fashion is created by the convergence between hip-hop fashion and preppy look, the meaning concludes pleasantness and casualness different from the past. Fourth, the prep-hop fashion is mainly composed of hip-hop fashion accessories, which express the authenticity of the hip-hop fashion to protect the non-mainstream characteristics. The design characteristics of the prep-hop fashion pursue the individuality of the contemporary fashion, which lacks originality due to commercialization. The development of the prep-hop fashion, as a new form that combined contrasting genres and trends, is expected to develop more publicly.

Parody, which is the device of humorous Postmodernism artists, has been from the comic immitation with the popular and well-known object. It's expressive techniques are very various such as similarity, transformation, exaggeration, irony, parados, inversion etc. and also it can be used another techniques of designer's will and ability based. Parody's effect consists of satire, mockery, scorn, ridicule, unexpectedness, defamiliarize, playfulness, wit, respect, esteem, wonder and so on of the original. So parody has a critical distance from the original, whichis the object of immitation. Ultimately, the expression of parody can be as extensive as from an ironic and funny inversion still containing the respect for the original to a contemptuous mockery. Nowadays Parodists have a tendency to use parody actively in order to criticize the real world or to meet the past with ironic recontextualize. And parody include the specific characters of postmodern design. So parody is widely known as a effective forms of expression in now-a-days our environment surrounded with the postmodern esthetics, and it's request will be increased rapidly. As a part of art, parody is apt to use widely in Fashion too. And from a historical standpoint it is to reconstitute the past with a critical eye and finally to become a new technique to create the new Fashion style with an intention of extension of design area.

A Gyeongju earthquake in the magnitude of 5.8 on the Richter scale (the moment magnitude of 5.4), which was recorded as the strongest earthquake in Korea, occurred in September 12, 2016. Compared with the 2011 Virginia earthquake, the moment magnitude was slightly smaller and its duration was 3 seconds, much shorter than 10 seconds of the Virginia earthquake, resulting in relatively minor damage. But the two earthquakes are quite similar in terms of the overall scale, unexpectedness, and social situation. The North Anna Nuclear Power Plant, which is a nuclear power plant located at 18 km away from the epicenter of the Virginia earthquake, had no damage to nuclear reactors because the reactors were automatically shut down as the design basis earthquake value was exceeded. Ground accelerations of the 2016 Gyeongju earthquake did not exceed the threshold value but the manual shutdown was carried out so that Wolsong Nuclear Power Site was not damaged. Damaged historic homestead house and masonry structures due to the Virginia earthquake have been repaired, reinforced, and rebuilt based on a long-term earthquake recovery project. Likewise, it will be necessary to carefully carry out an earthquake recovery planning program to improve overall seismic performance and to reconstruct the historic buildings and structures damaged as a result of the Gyeongju earthquake.
