The development of technology has changed the world drastically. Patent data analysis helps to understand modern technology trends and predict prospective future technology. In this paper, we analyze the patent citation network using the USPTO data between 1985 and 2012 to identify technology trends. We use network centrality measures that include a PageRank algorithm to find core technologies and identify groups of technology with similar properties with statistical network models.

In the analysis of competing risks data, some of covariates may not be fully observed for some subjects. In such cases, excluding subjects with missing covariate values from the analysis may result in biased estimates and loss of efficiency. In this paper, we studied multiple imputation and the augmented inverse probability weighting method for regression parameter estimation in the cause-specific proportional hazards model with missing covariates. The performance of estimators obtained from multiple imputation and the augmented inverse probability weighting method is evaluated by simulation studies, which show that those methods perform well. Multiple imputation and the augmented inverse probability weighting method were applied to investigate significant risk factors for the risk of death from breast cancer and from other causes for breast cancer data with missing values for tumor size obtained from the Prostate, Lung, Colorectal, and Ovarian Cancer Screen Trial Study. Under the cause-specific proportional hazards model, the methods show that race, marital status, stage, grade, and tumor size are significant risk factors for breast cancer mortality, and stage has the greatest effect on increasing the risk of breast cancer death. Age at diagnosis and tumor size have significant effects on increasing the risk of other-cause death.

During the reign of King Sejo, institutional arrangements led by the state was nearly accomplished. Meanwhile, numerous political scandals and exceptional situations took place during the reign of King Sejo. This had to do with the historical situation of this period; King Sejo took the throne in the way of usurpation, causing severe lack of legitimation, appointed his helpers as meritorious subjects throughout his reign, and frequently managed the state affairs in an abnormal way disregarding the existing procedures and customs. Especially, political activities of the royal relatives increased and they even became officials in this period, which provoked controversies. Aim of this research is examining how the ruling class justified the participation of members of royal lineage in political events during which normal and abnormal way of administrative process was practiced. Most of the existing studies on royal member activities under King Sejo emphasized its overly tyrannical and crippled aspects because of their inclination toward the king. These perspectives are still valid in understanding King Sejo’s personal political intention or style. Even it is true, however, that king’s personal will heavily influenced the royal member activities, their activities would not have been available without institutional foundations and common rules people of that period agreed upon. Activities of royal relatives were justifiable based on two principles contained in Choson’s bureaucratic system. First, it is a principle of paying respect to those of special status in terms of putting emphasis on descent. Non-official duties of assisting the king, participating in state administration, and conveying king’s command assigned to royal relatives were not only a matter of fulfilling the king’s needs but also a matter of paying respect to them. Secondly, it is a principle of emphasizing one’s contribution and capability, the most fundamental rule which lies in bureaucratic system. King Sejo justified royal relative’s official activities by arguing that meritorious subjects and royal relatives had to be treated equally based on their degree of contributions. This principle may have served as a critical cause for involving a number of royal members in official posts in his latter years. No one could have argued against him, which implies that the value of meritocracy was set as a common ground on the operation of government.

This article aims to investigate the effects of professor's communication on emotional response and class satisfaction for university students majoring in airline services. A total of 254 valid responses were applied for structural equation analyses. The outcomes of statistical analysis proved the evidence for a reasonable level of reliability and validity of this theory. The results are as follows. First, professor's verbal communication exerted a positive impact on positive emotion and a negative impact on negative emotion. Second, professor's nonverbal communication exerted a positive impact on positive emotion, indicating significant coefficients of body language. On the other hand, space language, voice language, and appearance language didn't. Professor's nonverbal communication exerted a negative impact on negative emotion, indicating significant coefficients of appearance language. On the other hand, body language, space language and voice language didn't. Third, positive emotion turned out to affect positively on class satisfaction and negative emotion did negatively on it. The findings identified how students could be satisfied with the class through the successful communication of the professor. Furthermore, the outcome provided a theoretical basis for adapting well to the airline industry and effectively performing field work.

In this study, we developed a scalp protect powder (scalp irritation abirritant). We proved this powder can lessen sensitivity of skin against diamine dyes (PPD, PTD, etc.) by carrying out safety test and clinical experiments. This scalp protect powder accelerates dyeing process, and reduces not only scalp irritation but also hair damage. Using our optimum formula, ammonia can be caught in liquid-crystalline structure, subsequently, bad odor is reduced dramatically.

This study is a paper that defines the space of Haedeungchon-myun Yangjumok Gyeonggi-do where Byeolseo of Cho Hyun-myung, a bureaucrat in the 18th century, was located as a political space. To this end, this study explains the aspect of setting up Byeolseo of Cho Hyun-myung and its use and aims to examine the meaning of space to Cho by analyzing the meaning of such an act. Furthermore, this study expands the discussion in a way of inferring the political meaning of the act of bureaucrats who established the base in Gyeonggi province, outside of the capital city. The bureaucrats in the latter part of the Joseon Dynasty set up Byeolseo in Gyeonggi province close to the capital and used it for residence and relaxation. The use of Byeolseo has been understood in the tendency of seclusion, which is post-political and post-secular. However, according to the analysis of Cho’s use of Byeolseo and its meaning, it can be said that the meaning of Byeolseo of the bureaucrats in the past was notably political. In addition, this study reveals that the act of seclusion cannot be seen as a concept of post-political or post-national.

The purpose of this study is to examine the sudden shift in the direction of consciousness and the change in worldview after the Japan’s annexation of Korea in the 1910s through an analysis of editorials related to clothing culture in the 1910s. This time period experienced a restructuring of the industrial structure, economic modernization, changes in customs, demanding of the self-discipline, and the promotion of hygiene, which was upheld as an aspect of modernization. Collectively, these measures were a device to transform Korea into a Japanese colonial society favoring Japan’s economic dominance. This study newly recognizes two fundamental aspects of colonial modernism and the imperialist exploitation of the 1910s. During this time period, out of 4275 editorials, 138 editorials (3.2%) were found to be related with clothing culture, and the most editorials on clothing culture were found in 1911 and 1913, 27 and 26 editorials respectively. The number of editorials on clothing culture dropped sharply in 1915 and 1917. As a result of the classification of editorials by subject, 94 out of 138 (68.1%) editorials were related to industrial development, 14.5% of these focused on the changing customs, 13.5% focused on warnings to refrain from purchasing luxury goods, and 5.7% focused on hygiene promotion. Further research must analyze the editorials belonging to each subject in detail to reveal a nuanced picture of the 1910s.

In Korea, the only remaining part of the Cotton Armor of the late Joseon period is a body armor or a vest. It was designated as Registered Cultural Property No. 459 in June 2010. However, there are some more Cotton Armors with appendage (e.g. wide fabric belt and chest protector) and helmets overseas. Therefore, it is essential to study the Cotton Armors from the overseas collections in order to study the full patterns on the Cotton Armor and Helmet. In this study, the patterns stamped on the Cotton Armor and Helmet were focused on which scholars have not yet identified. Such studies on the patterns of the Cotton Armor that were published abroad but not well known in Korea were also introduced in this study. To restore the patterns, we analyzed the prior studies and photos, collections from the National Museum of Korea and Metropolitan Museum of Art in New York, and references on the Taoist symbols, amulet and talisman. This study can be used as basic data for supplementing the future research the symbolism of the patterns and the restoration of the Cotton Armor and Helmet of the late Joseon period.
