The term "B film" is contrasted to the term "A film" and it has started life since the Great Depression. Film industry had planned the double bills for the audience attraction; double bills means the release of A film and B film. While A's is made to make profits, B's film is made to meet the balance. B film has two features of low budget and low technology. Nevertheless B film has its own style and aesthetics and ironically has made the film more creative and innovative. Historically, it has been related to European and American avant-garde. Robert Florey who is worthy of notice among the early B film makers has adapted and integrated the expressionist and avant-garde styles into the American feature. He also preferred the greater liberty generally afforded "B" directors. Florey has directed Murders in the Rue Morgue and The Florentine Dagger due to the success of his experimental films. Murders in the Rue Morgue shows the style and aesthetics of avant-garde through horror genre and The Florentine Dagger shows the style and aesthetics of avant-garde through thriller genre.

This study aims to understand the possibility of small city marketing strategies using B-grade cultural contents. This research focused on the case of Chungju City which applied B-grade cultural contents to city marketing. The process using B-grade cultural contents to small city marketing was investigated and hash-tags and comments on social media were coded and analyzed based on grounded theory. Also, the details were examined through in-depth interviews with the local government official in charge. The result has shown the characteristics of B-grade cultural contents describing the differences from the original B-grade culture as subcuture. First, publicity materials showed the characteristics of general B-grade culture such as retro, puns, and escape, showing the process of communication/participation/empathy. Second, improbability, intertextuality, extensibility, subversiveness, and authenticity were the five main factors for responses and empathy from the audience. Third, the ripple effect was formed through the simple narrative structure of 'intro-conclusion'. Finally B-grade cultural contents of Chungju showed new possibilities for sustainable small city marketing through the formation of new cultural assets.

This study discovers the general characteristics of B-class Emotional Advertisements and analyses their trend. A content analysis was conducted on 498 advertisements on-aired between 2015 and 2020, which were sampled from the advertisements registered in the TVCF(www.tvcf.co.kr), the largest advertisement web portal in the Republic of Korea. The analysis concludes that the B-class Emotional Advertisements, employed in a wide range of genre, is most incorporated in comedy/exaggeration genres and is on a rising trend due to 2020 COVID-19 Pandemic. Furthermore, it is confirmed that the utilization of B-class emotional advertisement has also increased in domain of non-commercial advertisements, such as Public Service Advertisements, Governmental/Organizational Advertisements, and Corporate Public Relations (PR) Advertisements. The study validates the transformation of the B-class emotional advertisements from a demonstration of an eccentric minority subculture to an epitome of a new and adventurous mainstream culture, successfully serving a central role in both the commercial and non-commercial sectors. Depicting the caricatures of the social, cultural and economic phenomenon and the recent surge of individual's depression, fatigue and pessimism, B-class emotional advertisements provide sympathetic and emotional alleviating ground for people that contributed to its rise.

This research is to identify how much toxic combustion gases are produced from Korea standardized real fire test (Class A&B) by using Room Corner Tester (RCT) and how much those gases are possibly dangerous to testing personnel by estimating the level of carboxyhemoglobin (% COHb). It is confirmed that testing personnel can be affected as more than 40% COHb from Class A 9th and 10th rating in respiration minute volume (RMV) 2 and from Class A 5th to Class A 10th rating in RMV 3 during the time for initial three minutes. Also, in the case of Class B real fire tests, although it is considered rather safe for the initial 1 minute, testing personnel can be affected as more than 20% COHb from Class B 16th to 20th rating in RMV 3 during total test time. Currently, the Korea standard is only focusing on the protection measures against the heat, but the it is neglecting the protection measures against toxic combustion gases. Therefore, according to this study, it is strongly recommended that testing personnel should wear a self-contained breathing apparatus, or the equivalence depending on the real fire test rating.

The Korean movies, and are suitable for "B-movie" for spending low budget and utilizing subculture factors such as kitsch, parody. Using surrealistic space and arbitrary language is the most prior element in constituting 'B-affection'. In that sense, Behind the Dark Night, Super Margin have characteristics overcrossing the media from comics to film. Despite absurd story, Behind the Dark Night has a realistic and concrete sense of what is the making films. The hero in Super Margin was swindled, so he strikes a blow the breeding-place of crime himself. In conclusion, showing comics characteristic aspects has been increasing comedy effects. But, on the other hand, Behind the Dark Night, Super Margin have pointed out that there are many kind of social problems such like career, fraud etc. In addition, they introspect the meaning what is that to making films.

An experimental study was performed to evaluate the applicability of current design code to the class B splice of SD600 reinforcing bars. Twelve simply supported beam and slab specimens with re-bar splices were tested under monotonic loading. Parameters for this test were re-bar diameter, concrete cover thickness, concrete strength, and stirrup spacing. Concrete strengths ranged 24.7~55.3 MPa. Most of the specimens were designed to satisfy the class B splice length specified by current design code. Average bar stresses resulting from this test were compared with the predictions by the KCI code provisions. Based on the result, the applicability of the current design code to SD600 re-bars were evaluated. The re-bar splices gave satisfactory performance for all D13 re-bar splices and for D22 and D32 splices with transverse reinforcement. On the basis of the test result, for D22 and the greater diameter bars, the use of either transverse reinforcement of the thicker concrete cover was recommended.

In March of 2014, after Eduwill's new TV commercial, Seo Kyung Seok, appeared as a model, unusually, various professional comedians have spontaneously made many TV ad parody contents. It is a kind of GCC (Gagman Created Contents), which is a content created by comedians if it is called User Created Contents (UCC) by a consumer voluntarily making contents. Various popular programs of TV stations such as tvN, KBS, SBS, MBC Eduwill TV commercial parody contents was broadcasted. Euduwill TV advertising parody contents can be classified as parody contents that mimic Eduwill CM songs and comic dancings by Seo Kyung Seok. In this study, we analyzed how the characteristics of class B culture such as 'twist' and 'satire' are reflected in Eduwill TV commercial parody, and discussed the correlation between advertisement, parody contents and socio-cultural phenomenon.

When the high power transistor is used for amplifier in microwave frequency, the bias of transistor is usually AB-class or B-c1ass because of power efficiency. The sweet spot point having small IMD signal compared with near neighborhood exicts frequently in the high power transistor using AB class bias or B-class bias. On the sweet spot, the magnitude and phase of the main and IMD signal of HPA output change as the input signal power change, respective the relative phase on the sweet spot changes rapidly. If we know exactly the magnitude and phase characteristics of IMD signal, we can design a more adequate linearizer and understand the characteristics of transistor. In this paper the magnitude and phase of the main and IMD signal of HPA output on the sweet spot are measured using the designed hardware.

근래, 혈청배지로 생산한 체외배양 수정란은 이식후, 낮은 수태율, 과체중의 산자 생산, 높은 유산율과 사망율 등 문제가 지적되고 있다. 그러나 무혈청 배지로 생산한 체외배양 수정란은 이러한 현상을 개선할 수 있다는 보고가 있어, 본 연구는 세포성장인자가 첨가된 완전 무혈청 배양액에서 생산된 수정란으로 2001년5월 부터 2002년 12월까지의 신선란 및 동결란으로 이식한 결과이다. 이식은 신선란 및 동결란에서 A급 수정란은 1개, B급 수정란은 2개를 장착 하여, 이식을 하였다. 이식사술은 인공수정경력이 10년, 이식경력 5년 이상의 수정사 5명이 이식한 결과로 신선란과 동결란의 수태율을 확인하였다. 신선란의 이식에서는 387두중 148(38.2%)두가 임신이 확인되었고, 동결란의 이식에서도 758두 중 265(34.9%)두가 임신이 확인되어, 신선란과 동결란과의 유의적 차이는 없었다. 위의 결과에서 무혈청배지에서 발생된 신선란 및 동결란의 이식결과 유의적 차이는 없었으나, 동결수정란의 내동성이 탁월한 것이 증명되었으므로, 앞으로 체외수정란의 대량생산으로 수정란이식의 상업화가 가능할 것으로 사료된다.
