Purpose: Social Network Sites(SNS) have been grown up as a public communication channel consumer frequently participate in. Most of food service brands are utilizing social media for advertising recently. As a result of SNS marketing, food service brands anticipate positive outputs from SNS engagement and consumer brand engagement so that we need to verify structural relationship among SNS characteristics, SNS engagement and consumer brand engagement. Research design, data, and methodology: This study identifies that SNS characteristics have effects on SNS engagement and examines relationship between SNS engagement and behavioral engagement. We conceptualize SNS characteristics as information quality, hedonic level and interaction. Furthermore, SNS engagement is composed of SNS participation, positive word of mouth(WOM). In order to verify the purposes of this research, research model and hypotheses were developed. All constructs were measured with multiple items developed and tested in the previous studies. Sample data were collected from 433 online survey panels and analyzed by using SmartPLS 3.2.9. Result: The findings of this research are as follows. First, information quality is positively related with SNS participation. Hedonic level and interaction have impacts on SNS participation and positive WOM respectively. Second, SNS participation has positive effects on positive WOM. Third, both SNS participation and WOM influence behavioral engagement respectively. Conclusions: The implications demonstrate that SNS characteristics such as information quality and hedonic level and interaction exert effects for consumer to participate in SNS brand page. Meanwhile, hedonic level and interaction influence on positive WOM but information quality doesn't. SNS participation and positive WOM affect consumer to engage in specific brand behaviorally as well. Therefore, food service brand marketer is required to manage SNS information quality and hedonic level and interaction among members to encourage SNS participation and positive WOM. As SNS participation and positive WOM increases behavioral engagement of consumer, marketer needs to incentivize SNS participation and look after situation of positive WOM and respond swiftly.

This study aims to analyze the style of men's suits and extract expressional words for the development of semantic differential scales of visual images according to the change in silhouette. Research methods are literature studies, case studies, and questionnaires. The stimuli were created using CLO 3D, a virtual sewing CAD. This study's results are as follows: 1) The British suit jacket has an angled shoulder line using thin pads, and a slightly higher waistline. The pants of the suit have a high waistline and two pleats, so the thighs of the pants are wide. The American suit jacket has a natural shoulder line, and the waistline is not emphasized. The width of the jacket is relaxed, and the length is long. The pants of the suit have a higher waistline, and the pants are wide as well. The Italian suit jacket has wide shoulders, and the waistline is connected lower with a soft curve, and the length is relatively short. The trousers of the suit are tapered and get narrower as it goes down to the hem. 2) Because it originated in the practices of true bespoke tailoring, traditional British suits have a far more 'fitted' silhouette than the mass-produced styles that became emblematic of the American style. By the late 1950s, a sack-style suit was standard American business attire. This technique gives the sack suit its characteristically 'boxy' silhouette. The "Continental" presented a highly tailored silhouette, with padded shoulders, a slim, tight-fitting chest, and a closely tapered waist. The story was that Italian culture valued aesthetics over all else and thus sought the 'slim' suit style as much as possible. 3) The main expressional words of visual images for men's suits differ greatly depending on the silhouette of suit. The visual images are ranked in the order of 'neat', 'classic', 'educated', 'hard', 'mature', for fitted silhouettes. The words of 'masculine', 'basic', 'comfortable', 'simple', 'mature', 'conservative', 'modern', are ranked for boxy silhouettes. And the words of 'slim', 'young', 'neat', are noted for slim silhouettes.

최근 널리 이용되고 있는 동영상 공유 서비스에서는 콘텐츠 추천 시스템이 매우 중요한 요소이다. 콘텐츠 추천을 위해서 일반적으로 사용자 선호도와 동영상(아이템) 유사도를 동시에 고려하는 협업 필터링을 사용하고 있다. 그러한 서비스는 주로 사용자의 검색 키워드와 시청시간과 같은 개인 선호도를 활용하여 사용자의 편의를 도모한다. 또한 동영상에 지정한 키워드를 중심으로 랭킹화한다. 그러나 한정된 키워드만을 이용한 동영상 유사도를 분석한다는 한계가 있다. 이런 경우 지정한 키워드가 아이템을 제대로 반영하지 못하는 경우 그 문제가 심각해진다. 이 논문에서는 교육 동영상으로부터 차별화된 의미를 갖는 모든 단어를 고려하여 유사도를 분석하며, 이런 경우 데이터와 연산의 규모가 방대하기 때문에 빅데이터 클러스터에서 처리하는 방법을 적용한다. 제안한 시스템은 빅데이터 영상 분석을 통해 동영상 공유 서비스 플랫폼의 기본 모듈로 활용될 것으로 기대한다.

This research article presents the work that is related to the application of different machine learning based similarity techniques on religious text for identifying similarities and differences among its various translations. The dataset includes 10 different English translations of verses (Arabic: Ayah) of two Surahs (chapters) namely, Al-Humazah and An-Nasr. The quantitative similarity values for different translations for the same verse were calculated by using the cosine similarity and semantic similarity. The corpus went through two series of experiments: before pre-processing and after pre-processing. In order to determine the performance of machine learning based similarities, human annotated similarities between translations of two Surahs (chapters) namely Al-Humazah and An-Nasr were recorded to construct the ground truth. The average difference between the human annotated similarity and the cosine similarity for Surah (chapter) Al-Humazah was found to be 1.38 per verse (ayah) per pair of translation. After pre-processing, the average difference increased to 2.24. Moreover, the average difference between human annotated similarity and semantic similarity for Surah (chapter) Al-Humazah was found to be 0.09 per verse (Ayah) per pair of translation. After pre-processing, it increased to 0.78. For the Surah (chapter) An-Nasr, before preprocessing, the average difference between human annotated similarity and cosine similarity was found to be 1.93 per verse (Ayah), per pair of translation. And. After pre-processing, the average difference further increased to 2.47. The average difference between the human annotated similarity and the semantic similarity for Surah An-Nasr before preprocessing was found to be 0.93 and after pre-processing, it was reduced to 0.87 per verse (ayah) per pair of translation. The results showed that as expected, the semantic similarity was proven to be better measurement indicator for calculation of the word meaning.

Objectives : The purpose of this sutdy was finding out the origin and daily dose of Allii Fistulosi Bulbus in Treatise on Cold Damage Diseases. Methods : In order to estimate the origin and daily dose of Allii Fistulosi Bulbus, I researched the Treatise on Cold Damage Diseases, Synopsis of Prescription of the Golden Chamber, Classified Emergency Materia Medica, Compendium of Materia Medica, and Huangdi's Internal Classic. Results : According to some important herbal textbooks, Allii Fistulosi Bulbus had no seed, was reproduced by rhizome, and its leaves were soft. Chongbaek in Treatise on Cold Damage Diseases did not include word 'raw'. The unit of the dose of it was the number of article. So Allii Fistulosi Bulbus in Treatise on Cold Damage Diseases was not Daepa but Jokpa, and was dried, and was round shaped bulb bigger than bean. The daily dose was 4, 9, 14 articles in Treatise on Cold Damage Diseases and Synopsis of Prescription of the Golden Chamber. These were estimated equal to 1, 2, 3 Ryang. 1 Ryang equals to 6.5 g in Treatise on Cold Damage Diseases, so the daily dose of Allii Fistulosi Bulbus was estimated 6.5 g, 13.0 g, and 19.5 g. I weighed the middle-sized Allii Fistulosi Bulbuses, the result was remarkably consistent with the estimated numerical value. Conclusions : In Treatise on Cold Damage Diseases, Allii Fistulosi Bulbus was dried bulb of Jokpa of Allium fistulosum Linn$\acute{e}$ and the daily dose was 4 or 9 articles, respectively equaled to 1 Ryang, 2 Ryang and 6.5 g, 13 g.
