This study analyzed the polarization of software education by analyzing the relationship between the average monthly total private education expenditure, software education expenditure, and academic achievement. For this purpose, data were collected and analyzed by surveying 2,780 parents of elementary school children nationwide. The results of this study are as follows: First, there was a statistically significant difference in children's academic achievement depending on whether or not they participated in software education. Second, the higher the children's academic achievement, the higher the percentage of participation in software private education expenditure. Third, there was a significant positive correlation between total private education expenditure and software-related private education expenditure. Fourth, although not statistically significant, there was a positive correlation between software private education expenses and academic achievement. In this study, software education provided by public education is not sufficient. For this reason, participation in private education and the amount of expenditure are increasing, and there is a gap in improving the main competencies of students according to household income.

The Ratio of APT jeonse to purchase price was still rising. The interaction of APT Purchase and Jeonse price indices by region analysis in order to analyze this phenomenon, and results were summarized as follows. First, because the regional APT purchase and jeonse prices appears the rise and fall differently by region, regional polarization was deepening. Second, the recently real estate market was analyzed the province's booming real estate and the downturn of the metropolitan area. So, the ratio of APT jeonse to purchase price was continued to rise. Finally, the Ratio of APT jeonse to purchase price changing rate is (+) increased if the APT purchase price changing rate is larger then the APT purchase price changing rate and smaller then is (-) decreased.

In 2009, polar codes, proposed by Arikan, are theoretically proven codes to achieve capacity with acceptable encoding and decoding complexity. Currently, polar codes using channel polarization phenomenon are studied in security and data compression fields etc. In this paper, we consider the practical communication system and propose the construction method of polar codes with finite length and fixed code rate. Also, we show the outstanding performance and corresponding construction method of polar codes found by heuristic simulation.

지금 건축계는 양극화 현상이 뚜렷한 것 같다. 사회의 일반적인 현상 즉 부자와 빈자가 양극으로 갈라지고, 중간층이 무너지고 없듯이 일이 밀려 바쁜 대형사무실과 일이 없어 절절매는 소형사무실만 존재할 뿐이라고 감히 말할 수 있지 않을까 싶다. 필자가 지금부터 이야기하려고 하는 것은 통계자료에 의한 것이지만 방금 한 말은 통계자료에 근거한 말이 아니고 주위의 상황을 놓고 한 말이다. 사무실 운영을 함에 장부 없이 하는 사무실이야 없겠지만 매 프로젝트마다 얼마나 남고 밑지는지 그리고 한해가 지나면 손익을 철저히 계산하여 다음해를 대비하는 사무실이 얼마나 있는지 잘 모른다. 다만 지난번 서울시건축사회에서 신규건축사 면허취득자 교육시 위와 같은 제목으로 강의를 한적이 있고, 또 유 걸선생 사무실을 방문했을 때 우리사무실의 누적된 자료를 공개할 용의는 없는가라는 질문을 받고 지금이 적당한 때라고 생각해서 이글을 쓰게 되었다. 유선생 말씀인즉 본인이 근무하던 덴버의 사무실은 30명 정도의 규모인데도 매주 화요일 오전에 각 프로젝트의 진행상황과 지출상황을 낱낱이 기록한 서류를 가지고 프로젝트 인원배분 및 진행속도를 채근한다는 것이다. 이제 우리나라의 사무실들도 이렇게 되어야 무한경쟁에서 살아남을 수 있지 않을까 생각하여 그동안 해왔던 자료를 일부 공개하려고 한다. 이보다 더 정밀하게 운영하는 사무실들에게는 부끄러운 일이 될지 모르겠다.

최근 대기업과 중소기업의 양극화 현상이 심화됨에 따라 청년실업률이 높아져도 중소기업의 취업기피 현상이 나타나는 모순된 상황에 처해 있다. 이러한 상태가 지속되면 우수인력이 중소기업에 올수 없고, 중소기업은 인적자원의 한계를 벗어날 수 없다. 따라서 이러한 문제를 해결하기 위한 방법으로 오늘날 우리생활에 큰 변화를 일으키고 성장 잠재력이 큰 스마트 모바일 사업의 활용을 통해 대기업과 중소기업과의 공생관계를 긴밀히 하여 중소기업의 활성화를 하고자 한다.

In this study, we examine other factors that may contribute to the decline in students' academic performance and educational attainment. Many media reports, as well as previous studies, have suggested that virtual learning is the main reason for the decline in students' academic performance. However, the 2020 National Student Achievement Survey, which was conducted in conjunction with the COVID-19 Distance Learning Environment Student Survey, showed that students were highly satisfied with distance learning (70-80%), and the analysis of the National Assessment of Educational Achievement showed that students' academic performance had already been declining year by year since 2017, with a general downward curve. For further confirmation, we analyzed the performance of high school students on mock exams and found that their performance was not normally distributed, but rather a right-skewed U-shaped distribution with a shrinking number of medians and severe polarization. We found that this phenomenon is not simply because of the mode or quality of the virtual classroom, but to a variety of factors, including environmental influences such as care and management at home, changes in investment in private education, increased time spent on online devices while taking virtual classes at the bottom, and increased time spent watching online content, games, and videos that are not related to learning.

Korean society recently witnesses a rapid lllcrease of suicide across all ages. In particular, suicide in old ages jumps up ill a very unexpected way. Furthermore, the order of suicide in the cause of death across all ages is becoming higher and higher in Korea. This study provides details of suicide that occurs in Korean society with the comparison to that of Japan at the descriptive level. It is not well known why suicide in Korean surges recently. Several previous research show the possibility that surging suicide is closely related to the worsened economic conditions especially since the economic crisis in 1997. They adopt economic growth, unemployment rate, income distribution, household finance index as economic indicators in their research. This study also adopts those indicators and conducts a correlation analysis in two periods, 1990-1997 and 1998-2004. It is found that there is no correlation between economic indicators and suicide in the period of 1990-1997. On the other hand, there is a very strong correlation between income distribution and suicide in the period of 1998-2004. Other economic indicators except income distribution does not have any significant correlation with suicide. This finding suggests that currently increasing suicide in Korea may be a result of economic polarization, which has been worsened since the economic crisis in 1997.

One of the reasons for low fertility rate in Korea is related to the delayed marriage among the population belong to marriage cohorts. The major goal of this study is to analyze how the economic resources such as level of education, whether employed or not, and occupation have affected one's marriage opportunity and how it is differed by gender. Meanwhile, the changes in the influence of economic resources and the changes in the marriage norms were also studied by analyzing 2% Census data in 1995, 2000 and 2005. Total number of 1.1 million men and women in their ages between 20 to 44 are included in data and binary-logistic analysis is used for statistical research. This study supports a traditional hypothesis that the influence of economic resources on probability of marriage is different by gender. More important academic contribution of this study is the quality of economic resources is becoming more important for men since Asian economic crisis and that the negative effect of it on women is declining since 2000. It is analyzed that the effect of marriage norm has recently decreased on the part of women. These findings suggest that there is a tendency of polarization of marriage market in Korea affected by economic polarization since Asian economic crisis.

최근 정보통신기술의 발전과 세계화의 진전으로 IT제조업의 생산 효율화를 통한 비용절감의 방안으로 각 생산공정의 국제분업이 이루어지게 되었다. 국제분업을 통해 국가는 비교우위의 생산요소에 집적을 통해 효율화를 이루게 된다. 하지만 이러한 국제분업을 통해 기술의 양극화 현상이 나타나게 되고 국제분업구조에서 기술중진국의 비교우위부문의 확보가 새로운 과제로 부상되었다. 따라서 기술중 진국이 장기적으로 국제분업구조에서 기술부문의 비교우위확보를 위해 민간부문과 공공부문에서 동시에 이루어져야한다.

자본주의 사회에서 기업은 이윤의 극대화라는 목표를 이루기 위해, 인간을 하나의 자원으로 간주하여 도구화 하는 경향이 있다. 그 결과 인간소외(alienation) 및 부의 양극화 현상이 심각한 사회적 문제로 거론되고 있다. 오늘날 경제성장에 따른 물질적 풍요와 번영이 인류사회에 행복을 가져다 줄 것이라는 통념은 '물질적 풍요 속의 정신적 빈곤'이라는 문제제기에 의해 그 위상이 흔들리고 있다. 자본주의가 인류사회의 행복과 공동번영에 기여하는 경제체제로서 역할을 다하려면, 자본주의 역시 시대의 변화에 맞추어 진화해야 한다. 본 논문에서는 새 시대에 걸 맞는 자본주의의 대안을 논의하고자, 저자 이재윤이 창시한 깨달음경영학(MOSEE;Management Of allSelves' Enlightenment and Empowerment)의 새로운 과학적 학문연구를 통해 새로운 실현성 영역을 추구하는 동시에, 깨달음경영의 새로운 5차원 요소인 영적 자원 및 자산(SRA:Spirit Resource and Asset)과 본질적으로 무(無)에서 유(有)를 창조하는 창조경영(MOC:Management Of Creation)에 대한 연구 및 인간의식 성장 방법론에 대하여 발표 하고자 한다. 이로써 4차 산업을 넘어서 21세기 신 문명 5차 산업 경영혁명을 성취 한다. 따라서 깨달음경영학(MOSEE)에 관한 고유한 철학, 고유한 탐구 영역, 이론, 방법, 기법, 도구, 운영 원리 및 활용 분야 등을 체계적으로 설명하는 것이 목적이다.
