본 연구에서는 대학교와 학교 현장의 연계를 통하여 진행된 실험교실의 사례에서, 3년간의 수업 후 평가회에서 나타나는 예비교사 공동체의 반성을 문화역사활동이론의 관점에서 분석하였다. 먼저, $Engestr{\ddot{o}}m$이 제안한 활동 체계를 이용하여 사회문화적 요소를 파악하였고, 반성의 양상을 '반성 주제의 다양성'과 '반성의 실제성'의 측면으로 구분하여 살펴보았다. 그리고 공동체의 반성과 실행의 순환 과정 속에서 나타나는 한계점을 살펴보았다. 분석 결과, 3년간의 수업 후 평가회에서 예비교사 공동체 반성의 사회문화적 요소는 변화하였는데, 수업평가회의 정례화, 도구의 도입, 평가회 운영 주체의 변화가 두드러지게 나타났다. 이 과정 속에서 반성의 주제는 다양해지고, 실제적인 논의가 이루어졌다. 그러나 시간 관리, 학생의 참여, 지도서인 '멘토의 역할'에 대해서는 반성적 실천이 발전되지 못하고 매번 비슷한 패턴의 논의가 반복되었다. 이러한 결과 분석을 토대로 활동체계의 측면에서 예비교사 공동체의 반성적 논의를 촉진시킬 수 있는 방법에 대하여 제언하였다.

본 연구는 금리변동성이 금리수준과 양의 상관관계가 있음을 밝힘으로써 현행 위험기준 자기자본제도 하에서 금리리스크의 측정에 사용되는 금리변동계수가 금리수준에 따라 달라질 필요가 있음을 제시한다. 이를 위해 본 연구는 국공채 금리 자료를 이용, 이자율의 역사적 변동성을 측정하여 이자율 수준과 금리변동성 간의 비례관계를 확인한다. 또한 균형이자율 모형 중 지수형 Vasicek 모형과 Cox-Ingersoll-Ross 모형을 통해 금리수준과 금리변동성의 상관관계를 분석한다. 이후 국공채 자료에 기반하여 두 이자율 모형의 모수를 추정하고 이에 따라 금리수준별 금리변동성을 측정한다. 이에 따르면 금리수준이 높을수록 금리변동성 역시 크게 나타난다. 금리가 2.8%일 경우 지수형 Vasicek 모형과 CIR 모형에서는 금리변동계수가 각각 0.9와 1.1로 현 제도 하에서 금리하락 시 적용되는 금리변동계수 1.5보다 작게 나타난다. 이는 금리리스크에 대응하여 보험사가 보유해야 하는 자기자본이 현재 수준의 60%와 73% 로 낮춰질 수 있음을 의미한다. 본 연구에서는 이러한 결과를 반영하여 수정 금리변동계수를 이자율 모형에 따라 금리수준별로 제시한다. 금리수준과 금리변동계수를 연동시킴으로써 금리리스크를 보다 합리적으로 측정하고 관리하는 방안을 제시하였다는 점에 본 연구의 의의가 있다.

Generally, the outcomes of the historical study in some domain would be a most fundamental and basic reference for understanding the essential and core component of them. Specially in case of social science, the importance of historical research much more emphasized that would be divided into independent academic field. In Korean history including fisheries business and industry, the most remarkable historic event would be the period of Japanese colonial rule that one of the most obstacle should overcome. Though the fisheries business and industry of Korea have considerable own history, the research and study of that not so much have been performed or investigated including the period of Japanese colonial rule. Most of the existing research of fisheries history have merely focused on partial topics like 'Fishermen's Association', 'Fisheries Industry Despoliation'. And the historical study of fisheries business and industry's overall status and trend in local area except Pusan also not enough. The aims of this study are exploring the fisheries trends and status during the period of Japanese colonial rule in Tongyeong and finding out the overall major fisheries business issues that would be a better understanding the Korean fisheries industry. Achieving that Objectives, over 800 articles of media, the Japanese government-general of Korea, and other historical data were gathered, refined and analyzed. This paper focused on of major fisheries topics and issues that including overall fisheries status, trends, fisheries catches, local fisheries cooperatives and fisheries exhibition during the period of Japanese colonial rule in Tongyeong. The result of this study shows that the status of fisheries in Korea had been deteriorated for exploitation of Japanese imperialism and Japanese fisheries capitalist during that period. Though the level of Tongyeong in fisheries was very high in terms of catches ratio and population of fisherman, the distribution networks of fishermen's association was not good enough. And the Tongyeong fisheries exhibition in 1922 has positive aspects for considering both composition of organization and educational activity. Even though the results and findings would be a helpful guidelines for understanding the fisheries business trends and status under the rule of Japanese imperialism, more research and study of that should be accomplished.

In this study, we collected articles published in the Publication of the Korean Astronomical Society (PKAS) from 1984 to 2021, and performed quantitative analyses of their various aspects. PKAS is the journal where authors can publish research papers in Korean as well as English. It seems to have an advantage of the better accessibility to all people than other astronomy journals in English only. From 1984 to 2000, the number of articles published in PKAS has been steadily increased. From 2000, the number of published articles showed a tendency to decrease slightly every year. After 2010, the number of articles in PKAS has shown a sharp decline until now. Interestingly, in this period it is found that the topics published articles became various, in particular, many articles concerning historical astronomy began to be published. PKAS was selected as an accredited journal in 2018. This is a very positive situation, and we think the future direction of PKAS is encouraging. Considering these circumstances, the PKAS is suggested to reflect ideas of "interdisciplinary fusion" and "diversity" in publishing articles in the journal for its promising future.

Purpose: Rheumatoid arthritis (RA) is a chronic multi-systemic disease that causes damage to the bone and connective tissues. This study was conducted in order to accurately measure the correlation between RA and periodontitis, and to obtain an unbiased estimate of the effect of RA on periodontal indices. Methods: In this historical cohort study, which was conducted from February to May 2011 in Hamadan city, Iran, 53 exposed people (with RA) were compared with 53 unexposed people (without RA) in terms of clinical periodontal indices (the outcomes of interest) including 1) plaque index (PI), 2) bleeding on probing (BOP), and 3) clinical attachment loss (CAL). Results: A sample of 106 volunteers were evaluated, 53 rheumatoid versus 53 non-rheumatoid subjects. There was a statistically significant correlation between RA and BOP (P<0.001) and between RA and CAL (P<0.001). However, there was no statistically significant correlation between RA and any of the periodontal indices. No correlation was seen between gender and any of the indices either. There was a strong positive correlation between age and all three periodontal indices (P<0.001). Conclusions: The present study indicated a potential effect of RA on periodontal indices. However, much more evidence based on a prospective cohort study is needed to support the cause and effect relationship between RA and periodontal indices.

The physical therapy that is in use nowadays, especially thermotherapy, aquatherapy and manual therapy, has been around since humans started to live on the earth. In primitive times, when men were injured while hunting, they washed the wound in clean water and dried it out in the sunshine. They also soaked their bodies in hot springs to decrease physical fatigue. This primitive Korean traditional physical therapy was in common use among people throughout the Koguryo, Koryo and Chosun dynasties. Historical records show that some kings in those days recommended to their men these methods to treat any chronic disease or illness. This was often thought of as a positive means of treatment. Korean traditional physical therapy has been developed, and the scientific effects of therapy have been proven. Korean traditional physical therapy is used extensively in hospitals and clinics to treat many kinds of diseases and illnesses. Unfortunately some methods that have not been medically substantiated as an effective treatment are being used by practitioners. In this situation there is an urgent need for scientifical research and data regarding any unproven physical therapy techniques.

We have investigated the correlation analysis between global temperature anomaly and two main factors: geomagnetic activity (aa index) of Earth external factor and CO2 of Earth internal factor. For this, we used NOAA Global Surface Temperature anomaly (Ta) data from 1868 to 2015. The aa index indicates the geomagnetic activity measured at two anti-podal subauroral stations (Canberra Australia and Hartland England) and the CO2 data come from historical ice core records and NOAA/ESRL data. From the comparison between (Ta) and aa index, we found several interesting things, First, the linear correlation coefficient between two parameters increases until 1985 and then decreases rapidly. Second, the scattered plot between two parameters shows a boundary of the correlation tendency (positive and negative correlation) near 1985. A partial correlation of (Ta) and two main factors (aa index, CO2) also shows that the geomagnetic effect (aa index) is dominant until about 1985 and the CO2 effect becomes much more important after then. These results indicate that the CO2 effect become very an important factor since at least 1985. For a further analysis, we simply assume that Ta = Ta(aa)+Ta(CO2) and made a linear regression between (Ta) and aa index from 1868 to 2015. A linear model is then made from the linear regression between energy consumption (a proxy of CO2 effect) and Ta-Ta(aa) since 1985. Our results will be discussed in view of the prediction of global warming.

Purpose: This study's objective is to examine the impact of firm-specific and macroeconomic factors on the business performance of non-cyclical and cyclical sectors in Indonesian listed firms. The evaluation of business performance holds paramount importance for the achievement and long-term viability of a company. Research Design Data and Methodology: The data for 61 non-cyclicals sector companies and 57 cyclicals sector companies was gathered over a 4-year period from 2018-2021. The model integrates firm size, leverage, and sales growth as firm-specific factors, with real GDP growth and inflation rate as macroeconomic variables. ROA and ROE are indicators of a firm's business performance. The regression models are estimated using the distribution of a dynamic approach with Arellano-Bond Panel Generalized Method of Moments (GMM) estimation. Results: The results of the pooled sample indicate that the historical ROA and ROE have a positive relationship with the business performance of all sectors, including both non-cyclical and cyclical industries. The ROE of non-cyclical enterprises is primarily influenced by firm-specific characteristics and macroeconomic influences. Conclusion: To ensure the successful implementation of the distribution of a dynamic approach towards enhancing corporate business performance, organizations need to take into account a combination of firm-specific factors and macroeconomic factors.

As the proportion of the elderly population in rural Korea has increased rapidly, the quality of life of the rural elderly has become a major public and policy concern. In this regards, most of the researches on rural elderly have focused mainly on the 'risk factors or problems' of rural areas, ignoring the 'positive or protective aspects' of rural community on the quality of life of elderly. This study attempts to explore the possible positive influence of rural community on the quality of life of elderly and to examine the linkage among ecological characteristics of the communities, social interaction and quality of life of rural elderly. To achieve this goal, a community case study was conducted in four Korean rural villages. The data were collected using participant observation method and in-depth interviews (person-to-person, group interviews). All the interviews were tape-recorded and transcribed verbatim for the analysis. The data was analyzed using the reflective qualitative analytic technique. The major findings of this study are as follows : All of the four villages have strong community ties and provide contexts which make it possible for older people to share their everyday life with neighbors and to actively participate as a community member. Although the four villages were geographically not far from each other, the pattern of social interaction and the nature of everyday-life of the elderly were nevertheless different depending on the ecological environment of each community, the relationship history among the community members, and the shared experience of historical events in recent Korean history. Elderly men have smaller networks and have less frequent contact with community members than elderly women. The political and practical implications of this study are discussed.
