        High level radioactive waste disposal repository is faced thermos-hydro-mechanical-radioactive condition. Factors according to these complex conditions are measured using multiple sensors installed in the disposal repository to check integrity of the structure. Wires of the sensors can be potential pathways of groundwater and nuclide flow and these pathways accelerates bentonite saturation. Therefore, it is worth to developing wireless sensors buried in the bentonite buffer which can communicate without wires. In start of the study, widely-utilized wireless communication methods including WiFi and LoRa are tested using compacted bentonite blocks to estimate the performance of them. Compacted bentonite blocks are prepaired using di-press method with metal molds and the dry density of them are about 1.6 g/cm3. All wireless communication methods are well communicated through the bentonite blocks over 50 cm. The further experimental tests will be conducted with different dry density and water contents. The results of these experimental tests give a possibility of wireless communications in compacted bentonite buffer and will be utilized for the design of wireless sensor systems for the repository monitoring.

        Southeast Asia is home to the Straits of Malacca and Singapore, one of the world’s most important sea lines of communication. The closure of the straits to international navigation may adversely affect the well-being of the global economy. On February 11, 2022, the Biden administration announced the new Indo-Pacific strategy, which will continue to deliver on AUKUS. For centuries, the proposed Thai Canal Project has been planned to revolutionize the shipping industry by bypassing the busy waters of the Straits of Malacca and Singapore. If the canal is built under the US Indo-Pacific Strategy, the pre-eminence of the Straits of Malacca and Singapore will not last long. This article analyzes the potential increase of navigation of nuclear-powered submarines through the Straits of Malacca and Singapore and its ensuing environmental implications from a viewpoint of international law. It discusses effects of the proposed canal plan in influencing the shipping industry should this “dream waterway” be constructed.

        현대사회는 평균수명의 증가로 인해 지적장애인의 성인기도 점차 길어지고 있는 추세다. 그러나 그에 상응하는 교육이나 재활은 턱없이 부족한 실정이다. 특히, 성인이 된 지적장애인이 사회구성원으로 살아가 는 데 필수적인 의사소통 및 사회화 능력을 향상시키는 훈련은 좀처럼 찾아보기 어려운 실정이다. 본 연구 는 지적장애를 가진 성인의 의사소통 능력 및 사회화 능력에 재활승마가 미치는 영향을 분석하는 데 그 목적이 있다. 본 연구를 수행하기 위해 통제집단 사전사후 실험설계를 사용하였고, 실험집단과 통제집단은 각각 20명의 지적장애 성인으로 구성하였다. 먼저 두 집단에 의사소통과 사회화 능력에 대한 검사를 실시한 후, 실험집단을 8주 동안 16번의 재활승마 프로그램에 참여시켰다. 본 실험설계의 분석을 위해 실험군과 대조군의 동질성을 검증하였다. 그런 다음 재활승마가 지적장애 성인의 의사소통 능력과 사회화 능력에 미 치는 영향을 측정하기 위해 실험집단과 통제집단에 대한 사전사후 검사를 분석하였다. 분석 결과, 설계한 실험집단과 통제집단의 동질성이 나타났고, 재활승마에 참여한 실험집단은 참여하지 않은 통제집단과 비교 했을 때 의사소통과 사회화 능력에서 유의미한 향상을 보였다. 본 연구는 지적장애 성인의 의사소통 및 사회화 능력의 증진을 위해 체계적인 재활승마 프로그램을 기획·공급·확대할 필요가 있다고 제언한다.

        In this paper, a study was conducted on the analysis of communication circuit faults using oscilloscope waveform analysis. Circuit resistance was calculated based on voltage and operating current values using a simple equation, and it was confirmed that the increase in resistance of the communication circuit could be analyzed by analyzing the voltage level during transmitter operation. By combining information of the controller ID, the location of the fault was identified and it was concluded that the location of the fault can be quickly found by analyzing the oscilloscope waveform and the controller ID information. Additionally, the value of communication line contact resistance can be calculated using a simple equation, and the location of the fault can be found by analyzing the communication voltage level and ID information.

        The cellular communication network factor (CCN) family proteins regulate many biological events such as angiogenesis, tumor growth, placentation, implantation, and embryogenesis. The expression and function of CCN1, CCN2, and CCN3 at the maternal-conceptus interface are established in humans and rodents, but little is known about the role of CCN4 to CCN6 in the reproductive organs in any other species. Several studies in transcriptome analysis in pigs have shown that the expression of CCN4 and CCN6 increases in the endometrium during early pregnancy. However, their expression, regulation, and function in the endometrium throughout the estrous cycle and pregnancy have not been fully understood in pigs. Thus, we determined the expression, localization, and regulation of CCN4 and CCN6 during the estrous cycle and at the maternal-conceptus interface in pigs. We found that the levels of CCN4, but not CCN6, changed during the estrous cycle. The levels of CCN4 were greater during mid- to late pregnancy than in the early stage, and the levels of CCN6 were greatest on Day 15 of pregnancy. CCN4 and CCN6 were detected in conceptus tissues during early pregnancy and in chorioallantoic tissues during the later stage of pregnancy. CCN4 mRNA was mainly localized to epithelial cells, CCN6 mRNAs to epithelial and stromal cells in the endometrium. In endometrial explant cultures, CCN4 expression was increased by progesterone, and CCN6 expression by interferon-γ. These results suggest that CCN4 and CCN6 may play roles in the establishment and maintenance of pregnancy by regulating the endometrial epithelial cell functions in pigs.

        In this study, when a communication wire harness is defective due to long-term operation of a vehicle with a high-speed CAN communication network, the unique ID information of each controller and the oscilloscope waveform are analyzed to find defects. As a result of the experiment, it was possible to know whether the circuit of the main wiring was disconnected by the differential voltage analysis, and it was possible to confirm whether the sub-wiring was disconnected due to the generation of saw blade waveforms in the bus idle part. In addition, the fault location could be found with controller ID information and communication circuit analysis.

        In 2022, the Serious Accident Punishment Act was implemented, emphasizing the responsibility of managers at workplaces where serious accidents occur in order to reduce serious accidents that occur frequently throughout the industry and promote worker safety. Currently, it is applied only to workplaces with 50 or more workers, but from 2024, it will be applied to small businesses with fewer than 50 workers. Although these small-scale workplaces act as steppingstones in various fields, the rate of serious accidents is high due to the relatively poor environment and lack of human resources and financial capabilities. In this regard, we intend to examine effects of the Serious Accident Punishment Act on small-scale information and communication companies and to drive countermeasures.

        This study attempts to examine the distributions and characteristics of language forms and learning activities necessary for communication used in the middle school textbooks based on the 2015 revised national curriculum. To this end, 12 textbooks were analyzed and compared by grades and 4 textbooks by different publishers. The results are as follows: 1) Of the 38 language forms required for communication in middle school textbooks, 23 forms were commonly addressed in all the textbooks, while 12 forms were optional or missing, which may cause problems in articulated learning. 2) Even in the same language form, the level of difficulty increases as the grade goes up, which follows spiral curriculum. 3) Some language forms were omitted in the list presented in the 2015 revised curriculum, where only examples were presented without explanation. Explicit explanations need adding with elaborately classified examples. 4) Although the activities in the textbooks focus more on language acquisition than language use, they are well-organized to practice core language forms focusing on meaning in a controlled manner and gradually apply them to real life situations.

        Purpose: This study verified the effects of simulation-based communication education on the problem-solving process, communication self-efficacy, and communication ability of nursing college students. Methods: As an experimental study of single-group pre- and post-design, data were collected from April 12 to June 18, 2021, using a self-report questionnaire from 55 Year 4 nursing college students in city D. The collected data were analyzed in terms of frequency, paired t-test, and Pearson's correlation coefficients using the SPSS/WIN 23.0 program. Results: Our findings indicated that there were significant differences between the problem-solving process (t=-20.54, p<.001), communication self-efficacy (t=-15.31, p<.001), and communication ability (t=-3.62, p=.001) in communication before and after simulation-based communication education. Following simulation-based communication education, the communication ability of nursing students was evaluated through the problem-solving process (r=.46, p<.01), self-efficacy in communication (r=.37, p<.01), and problem-solving process by a doctor. Furthermore, it was found that there was a significant positive correlation with communication self-efficacy (r=.16, p<.01). Conclusion: It can be expected that the simulation -based communication education will improve nursing students’ problem-solving process, communication self-efficacy, and communication ability and thus contribute to high-quality nursing in related clinical situations. In addition, for a more effective communication education, research that could develop various scenarios in the clinical field and verify the effectiveness is required.
