  • Terrestrial broadcasters are devoting great efforts in order to increase sense of reality that would help viewers feel as if they were watching events on site by producing-depth, differentiated news and offering a variety of information to them. They maximize news video graphic effects by replacing news set and install large display units, rail camera, and Jimmy Jib camera. This study aims to grasp whether there is any difference among the main evening news of the three major terrestrial broadcasters. KBS, MBC, and SBS used 18%, 15%, and 12% of graphic usage hours respectively while the number of graphic usage cases amounted to 267, 329, and 276 for each of them. The number of cases where in-depth news report hours exceeded three minutes that require increasingly more virtual reality graphic technology production was 16 for KBS, 7 for MBC, and 5 for SBS. MBC showed the highest number of uses in graphics while KBS showed more graphic use hours than the other two. There have been a number of preceding studies on news contents, but it is significant that this study looked at how much graphics technologies are used in such news video contents.

  • The purpose of this study was to identify a support method for the introduction of metaverse-based classes (MBC) in home economics (HE) education. This was achieved by diagnosing the stages of concern and levels of use exhibited by HE teachers applying the concerns-based adoption model (CBAM). Questionnaires were sent to a convenience sample of middle- and high-school HE teachers using the KSDC (Korea Social Science Data Center). Overall, 271 responses were received, and the data were analyzed using KSDC E-STAT 3.0 and SPSS 28.0.1.1. The results were as follows: First, regarding the level of knowledge of MBC, the introductory level was the most common (139 respondents, 51.3%,), followed by the beginner level (81, 29.9%), the intermediate level (28, 10.3%,), the advanced level (12, 4.4%), and the master level (11, 4.1%). Average responses on a 5-point Likert scale to questions about the use of metaverse in HE classes were as follows: possibility (4.02), necessity (3.82), and usefulness (3.90). Second, HE teachers' stages of concern in MBC were as follows (in descending order): unconcerned - stage 0, and information - stage 1 (86.9), personal - stage 2 (85.6), management - stage 3 (80.9), collaboration - stage 5 (57.5), consequence - stage 4 (57.4), and refocusing - stage 6 (55.2). Third, the use of MBC was highest for orientation - level 1 (173 respondents, 63.8%), followed by non-use - level 0 (34, 12.5%), preparation - level 2 (29, 10.7%), mechanical - level 3 (15, 5.5%), refinement - level 5 (8, 3.0%), renewal - level 7 (8, 3.0%), routine - level 4 (3, 1.1%), and integration - level 6 (1, 0.4%). Many HE teachers had heard about MBC but were in the introductory level of not knowing what it is, and at the stage of being unconcerned or wanting to know about MBC. Of the 271 respondents, only 35 used metaverse in classes. Therefore, it is necessary to provide teacher training opportunities that provide basic information on the significance and implementation of MBC for HE teachers. Also, an MBC guideline book should be developed and distributed to HE teachers. Finally, a teacher community meeting is needed to share the expertise of teachers with substantial experience in using MBC.

  • This study examines how the development and value of dresses shown in MBC historical dramas have changed with the overall change of the dramas. As for the research method, the second data analysis was done with literature study which was supplemented with interviews with the wardrobe team of MBC production design center. Historical dramas produced by MBC have gone through the developmental period, legitimate historical drama-oriented period, stagnant period, and historical dramas-modernized period. The value of costume in each period is as follows: Costume in the developmental period is considered only as part of drama setting. During legitimate historical drama-oriented period, it carries value as educational data and historical replica produced by historical research. Production design including costume obtains its own value in the stagnant period although the production of historical dramas decreases dramatically. And lastly, in the historical dramas-modernized period, costume starts to have commercial value as cultural contents. Historical drama costume may contain important value in terms of education and history, even though there has been controversy on TV historical dramas' role: they should focus on reproducing historical facts or they should support writers' creativity.

  • The development of prolong and severe drought can directly impact on the environment, agriculture, economics and society of country. A lot of efforts have been made across worldwide in the planning, monitoring and mitigation of drought. Currently, different drought indices such as the Palmer Drought Severity Index (PDSI), Standardized Precipitation Index (SPI), Standardized Precipitation Evapotranspiration Index (SPEI) are developed and most commonly used to monitor drought characteristics quantitatively. However, it will be very meaningful and essential to develop a more effective technique for assessment and monitoring of onset and end of drought. Therefore, in this study, the hidden Markov Bayesian classifier (MBC) was employed for the assessment of onset and end of meteorological drought classes. The results showed that the probabilities of different classes based on the MBC were quite suitable and can be employed to estimate onset and end of each class for meteorological droughts. The classification results of MBC were compared with SPI and with past studies which proved that the MBC was able to account accuracy in determining the accurate drought classes. For more performance evaluation of classification results confusion matrix was used to find accuracy and precision in predicting the classes and their results are also appropriate. The overall results indicate that the MBC was effective in predicating the onset and end of drought events and can utilized for monitoring and management of short-term drought risk.

  • Model Based Compensator(MBC) is recently used for the analysis of multi-variable control in frequency domain. Target loop is designed by the demanding requirements such as cross-over frequency, disturbance rejection in low frequency domain, zero steady-state error, identification of maximum and minimum singular values and sensor noise rejection in high frequency domain. Loop transfer recovery will be continued in frequency domain until the plant with MBC comes close to the target loop. In this study, the technique using MBC is applied to the elevator vibration control system. It is found that this technique is very effective to control the vibration system.

  • Background: Male breast cancer (MBC) is a rare disease that accounts for less than 1% of all cancers in men and less than 1% of all diagnosed breast cancers. In this study, we retrospectively evaluated the clinicopathological features, treatment options and overall survival in Kurdish MBC cases. Materials and Methods: Seventeen MBC were referred to Department of Radiation Oncology in Imam Reza Hospital, Kermanshah, Iran, between 2010 and 2016. Immunohistochemical analysis was performed for ER, PR and Her2 biomarkers and FISH for those with Her2 2+. Median follow-up period was 30 months (2-65 months). We excluded from the study patients who did not have follow-up after initial diagnosis. Treatment methods were chemotherapy, radiotherapy, hormonal therapy, target therapy and palliative care. Survival was estimated by the Kaplan Meier method (Prism 5). Results: The mean age at diagnosis was $49.24{\pm}17$ years (range, 24-85 years). Grade II was the most grade in MBC (65%). Fourteen patients (82%) had invasive ductal carcinoma, one (6%) had ductal carcinoma in situ and 2 (12%) had invasive papillary. ER, PR and Her2 were significantly positive in 14/17, 8/17 and 2/17 cases, respectively. The treatment included modified radical mastectomy for most patients. Chemotherapy with TAC and CEF regimens was delivered to 15/17 cases. Tamoxifen therapy was delivered to 14/17 cases. Three stage IV patients received Avestin and two with Her2 3+ were given Trastuzumab (Herceptin). Patients received adjuvant radiotherapy following surgery and chemotherapy. The site of metastasis was the bone in 2 cases, lung in 1 case and liver in 1 case. Zoledronic acid (Zometa) was prescribed for patients with bone metastasis. Five-year overall survival rate was 64%. Conclusions: MBC is rare. Thus, we need larger studies are in collaboration with several research centers in the field of breast cancer. ER positive, grade II of invasive ductal carcinoma, stage II and right side happened more with MBC. Overall survival is similar to other studies.

  • In spite of many advantages of Meteor Burst Communications(MBC) on its transmission channel, the fact that its duty rate is less than10 percents is a considerable deficiency of MBC. To overcome with this deficiency without paying large cost, we use a direct sequence(DS)-spread spectrum(SS) method applying a reference code to improve the duty rate on the transmission channel. This method doesn't need to add the components for acquisition or tracking the signal so that it keeps the cost efficiency the MBC has as well as improves the duty rate on the transmission channel. The improvement by this method is more significant when the received signal is weak. Simulation results show that if we increases the process gain (Gp) by 10 dB when the average burst length is 50ms, the burst length tends to be extended more than 220% of its average length, 160ms, and the frequency of generating this phenomenon increases 3.1 times more.

  • This study deals with South Korea broadcasting reporters reporting North Korea issues focusing on KBS and MBC. More specifically, this study focuses on what kinds of broadcasting reporting restriction factors are in reporting North Korea issues in Korea. In order to achieve the goal of this study, this study attempted the depth-interview with six broadcasting reporters working on KBS and MBC. As study results, this study found out that Korean broadcasting reporters were sensitively influenced by public opinions concerned about a specific North Korea issue and political situations that a North Korea issue was positioned. In order to overcome such kinds of reporting restrictions in reporting North Korea issues, this study suggests that KBS and MBC needs more professional manpower dealing with North Korea issues and outside help such as civic social associations.
