In the M-ary DCSK system up to now, as M increases, the distance between constellation signal points becomes closer and performance deteriorates. we propose a hybrid modulation scheme based on PPM and DCSK to improve the BER performance. one part of the bit is modulated by the PPM and the other part by DCSK. Thus, the information bearing signal is modulated simultaneously according to the selected pulse position of the PPM determined by the information bit and the additional information bit. The analytical BER performance of the proposed plan is derived and verified by simulation. The results show that the proposed scheme outperforms conventional M-DCSK, code index modulation DCSK and rectified code index DCSK in additional white Gaussian noise and multipath Rayleigh fading channels.

The study investigates a promising sustainable crop-insurance risk mitigation plan, namely, Group Risk Income Protection (GRIP) insurance, for the cultivation of Para rubber, a crop for which Southern Thailand constitutes over half of the national harvested area, but which recently experienced a shift in prices and yields, substantially affecting farmers. The research takes as its starting point historical data covering the 2001-2018 period for this crop's cultivation in three of Thailand's Andaman South Coast provinces - Trang, Krabi, and Phangnga. The results indicate that, from a relatively high base in 2001, Trang's yields dropped sharply before a more gradual decline (apparently still ongoing), whereas those for Krabi and Phangnga followed a smoother downward trajectory throughout the period. Meanwhile, prices everywhere rose steadily before falling from 2011 onwards - a decrease that shows no signs of abating. The yield/price relationship was negative for one province and slightly positive for the other provinces. Furthermore, all provinces' Para rubber income initially grew continually but fell after 2011, with this trend seemingly persisting to this day. The paper's findings suggest that, after early moves to entrench GRIP insurance, it looks set to become a feasible option for Para rubber, making policy agreement details an interesting subject for subsequent investigations.

Global environmental problems are growing, and the importance of buildings with high energy consumption has been emphasized. In Korea, the Ministry of Land, Transport and Maritime Affairs has been promoting the mandatory zero energy building since 2020, and guidelines related to the zero energy building have been developed. In addition, based on the "Energy-saving Design Criteria for Buildings" of the "Green Building Promotion Act" in Korea, the standards for energy-saving design are specified and the energy saving plan is written. Besides, the 'Energy-saving construction standards for eco-friendly houses' also specify insulation, machinery, equipment, and sunshade. Also, there is little consideration about the cost such as construction cost and material cost which should be considered important in the construction stage. Therefore, this study aims at analysis of building type and energy performance versus materials for energy saving building design considering energy performance in planning aspect of initial design stage. In this study, because the variables can not be neglected in this study, it is selected as the lecture facility of the 'K' university campus building which can consider the remaining factors except the passive design element as the control variable, Energy performance analysis.

The number of freshmen at universities is decreasing due to the recent decline in the school-age population, and the survival of many universities is threatened. To overcome this situation, universities are seeking ways to use big data within the school to improve the quality of education. A study on the prediction of dropout students is a representative case of using big data in universities. The dropout prediction can prepare a systematic management plan by identifying students who will drop out of school due to reasons such as dropout or expulsion. In the case of actual on-campus data, a large number of missing values are included because it is collected and managed by various departments. For this reason, it is necessary to construct a model by effectively reflecting the missing values. In this study, we propose a university student dropout prediction model based on eXtreme Gradient Boost that can be applied to data with many missing values and shows high performance. In order to examine the practical applicability of the proposed model, an experiment was performed using data from C University in Chungbuk. As a result of the experiment, the prediction performance of the proposed model was found to be excellent. The management strategy of dropout students can be established through the prediction results of the model proposed in this paper.

This study sets the research goal of reducing energy consumption which 'H' University Industry-University Cooperation Foundation and resident companies are concerned with, as well as conducting policy research and data analysis. We tried to present a solution to the problem using the technique. The algorithm showing the greatest reliability in the power of the model for the analysis algorithm of this paper was selected, and the power consumption trend curves per minute and hour were confirmed through predictive analysis while applying the algorithm, as well as confirming the singularity of excessive energy consumption. Through an additional sub-sensor analysis, the singularity of energy consumption of the unit was identified more precisely in the facility rather than in the building unit. Through this, this paper presents a system building model for real-time monitoring of campus power usage, and expands the data center and model for implementation. Furthermore, by presenting the possibility of expanding the field through research on the integration of mobile applications and IoT hardware, this study will provide school authorities and resident companies with specific solutions necessary to continuously solve data-based field problems.

This research aimed at investigating policy change process of after school contracting out and suggesting future alternative. Also, this research conducted a literature search for the research data related to policy and related regulations. As the result of investigation, the Ministry of Education established management plan for after school, however there have been changes in policy, e.g. contracting out was executed from 2004 to 2008 upon autonomy of unit school through school steering committee deliberation(consultation), while standardized procedure was conducted, which was suggested in 'After school operation guideline', produced in cooperation between the Ministry of Education and municipal ministry of education from 2008 to 2015, while since 2016, contract law should be applied when after school contracting out is adopted. Policy change since 2016 is based on the legal necessity that contract law should be followed as the contract size of after school contracting out has become larger along with necessity of clarity of after school contracting out. Nevertheless, there's a worry that quality of after school education could be degraded due to lowest price bidding. The government suggested an alternative to prevent excessive price competition by paying a regular rate of basic price as personnel expenses, however this research suggested a plan to enact an ordinance in regard of specialty of after school educational activities and cities and provinces as the fundamental solution plan.

This study aimed at exploring the influence of 'Healthy couple relationship' education on the relationship formation competencies and marriage values of high school students. To achieve the research objective, the 'Healthy couple relationship' lesson plan developed by the author was executed in two high schools for eight weeks from September 1 to November 3, 2018 from which the effects were analyzed. The results are as follows. First, the 'healthy couple relationship' education for high school students has been effective in improving their relationship performance, which is a part of the home economics curriculum. In S high school, the paired t-test of pre-/post-test comparison results showed statistically significant differences in the areas of 'communication', 'conflict resolution' and 'relationship formation performance'. For Sejong City campus-type joint curriculum group, where Wilcoxson signed-rank test was applied due to small sample size, showed that the overall scores as well as all the subsections of 'relationship formation performance' (i.e., 'communication', 'self-understanding', 'conflict resolution', and 'empathy') have improved, although not statistically significant. Second, the 'Healthy couple relationship' education for high school students had positive effects on the marriage values of high school students. In S high school, students' perception of marriage values rendered a statistically significant positive change, while in campus-type joint curriculum in Sejong City, no statistical significance was detected. In conclusion, the 'Healthy couple relationship' education can help high school students build positive values by cultivating their 'relationship formation competence', which is a part of the competencies listed in home economics curriculum, and also broaden their understanding of marriage, by acquiring knowledge and skills to build healthy couple relationships, and learning to implement the knowledge and skills in their own lives.
