혈관에 흐르는 혈류 속도의 측정은 혈압 및 심박수와 관련된 혈류의 역학적 변화를 관찰하는 데 있어서 주로 사용되는 방법 중의 하나이다. 이 혈류 속도는 일반적으로 도플러 효과에 의하여 주파수가 변화하는 현상을 이용하여 추정하게 된다. 그런데 기존의 주파수 추정 방법들은 시불변 시스템을 가정하고 있지만 실제 혈관 속은 혈구가 일정하지 않은 속도를 갖는 시변 시스템이라 할 수 있기 때문에 이러한 시변 특성이 강한 경우 기존의 방법을 이용하게 되면 그 성능이 저하되는 경향을 보인다. 또 피시험자의 몸 상태에 따라서 서로 다른 주파수 변화 추이를 보이므로 하나의 고정 변수로써 최적화된 성능을 기대하기도 어렵다. 그러므로 본 논문에서는 시변 시스템에서 좋은 성능을 갖는 가변 망각 인자(variable forgetting factor, VFF)를 사용한 순환적인 완전 최소 자승법(recursive total least squares, RTLS) 기법을 이용한 주파수 추정 방법을 제안한다. RTLS란 TLS 기법을 순차적으로 계산하는 방법으로 시변 적응력을 향상시키는 방법이다. 또한 이 기법에 가변 망각 인자(VFF)를 적용시키는 것은 시변 시스템에서 외부적인 변화에 대하여 좀더 효율적으로 대응할 수 있기 위함이다. 기존의 방법과 성능 비교를 위하여 컴퓨터 시뮬레이션을 하였으며 그 결과 시변 시스템에서 본 논문에서 제안한 VFF를 이 용한 RTLS 기법이 보다 향상된 성능을 가지고 있음을 확인 할 수 있었다.

It is not the water veins themselves that are distributed on Earth that are harmful, but the water vein waves generated from the water veins are harmful to human health. The natural frequency of the Earth is 7.83 Hz, but in order to sleep deeply, you must go down to a delta wave of 2 to 3.99 Hz, which is lower than this frequency, to achieve the deepest sleep and maintain your health. However, if you sleep in a place with dowsing waves, the dowsing waves interfere with your brain waves, making it difficult to sleep well, and you may have nightmares. Even when you wake up, your body is not refreshed and your fatigue does not go away, so you feel tired and tired easily. If this phenomenon continues, the body's resistance decreases and immunity weakens, which can eventually cause illness and cause various diseases, which can harm one's health. In other words, the safest and most effective way to deal with water veins is to avoid places with water veins and simply change your sleeping position to a place without water veins, and you can live a healthy and happy life through examples.

Is an artificial intelligence robot, a non-human beings newly emerging in the age of technology, a threat to human beings, or a mutual cooperation or ensemble with human beings? The desire to control nature through the use of the power of science and technology is manifested in the fear that humans can annihilate themselves. This study attempts to identify the problems of Cartesian epistemology underlying these questions and fears and to answer these questions based on Merleau - Ponty 's ontological ontology using the Ontology and Latour' s ontology and technological philosophy. The cogito derived from the Cartesian philosophy became the basis of the structure of dichotomous epistemology of 'subjectivity and objectivity' based on human - reason. In the human-centered world, all non-human beings were tools or controls for humans. The problem of the modern people is not only to get help from the natural scientific methods to control the nature including man, but also to think that scientific method is the only way to understand the world. In criticizing this, Merleau-Ponty shows that the body mediates between human beings and non-human beings, and provides a possible ontological basis for the ontology. Merleau - Ponty 's phenomenological methodology and ontology are newly developed by Simondon under the influence of phenomenological philosopher and phenomenology. The relationship between human beings and nonhuman beings by Simondon appears as an ensemble of human and technical objects or a mutual co - operation of human and technical objects. In particular, Latour goes a step further in Simondon and defines all the bodies living in the world as actor-network theory, denying the core concept of modernity. Merleau - Ponty 's phenomenological view can be a new possible basis for the philosophical discussion of the technological age. We will see that the problem itself can be solved by shifting modern fear to a phenomenological attitude.

당뇨병환자에서 혈당조절의 중요성은 '앙꼬 없는 찐빵' 또는 '김 없는 김밥'과의 관계와 같다. 당뇨병이 우리가 먹은 음식이 우리 몸에서 잘 활용되지 못하고, 소변으로 당이 넘쳐흘러서 나오는 현상을 보고 붙여진 이름인 것을 생각하면 둘 간의 관계는 땔래야 땔 수 없는 관계라 할 수 있습니다. 우리가 무서워하는 당뇨병의 합병증은 혈당조절을 잘 하게 되면 많은 부분 예방이 가능하다는 것을 알 수 있습니다. 제 1형 당뇨병의 대표적 연구인 DCCT 연구 결과를 보면 당화혈색소를 8.0%에서 7.2%로 낮추면 망막증의 진행을 40$\sim$50%를 줄일 수 있었습니다. 제 2형 당뇨병의 대표적 연구인 UKPDS연구는 당화혈색소 1%를 줄이면 미세혈관합병증은 37%, 심근경색은 14% 감소된다는 것을 확인해 주었습니다. 그 이외에도 많은 연구들에서 결과의 차이는 있지만 적극적이고 엄격한 혈당조절은 합병증의 발생을 예방하며, 발생된 합병증의 진행 속도를 늦출 수 있는 가장 효과적인 방법으로 증명하고 있습니다. 그런데 여러분들께서는 위에 언급한 '당화혈색소'를 알고 계십니까? 공복 혈당조절 목표를 알고 계십니까? 식후 혈당조절 목표를 알고 계십니까? 혹시 모르고 계시다면 100미터 출발 선상에서 출발 신호가 났지만 어디로 달려갈지 모르고 있는 것과 같습니다. 아무리 잘 달리고 훌륭한 선수라도 뛰어갈 방향을 모르고 있다면 좋은 성적을 낼 수 없는 것과 같습니다. 혈당조절의 중요성을 알고 관리 목표를 알고 현재 나의 수치를 그 목표를 행해 열심히 실행한다면 건강한 삶을 영위할 수 있습니다.

It is generally accepted that the political philosophy of Merleau-Ponty is called western Marxism or existential phenomenological humanism. I would like to examine and orientate his political theory in detail in terms of embodiment. In what follows, I criticize its own conception of subjectivity as a philosophical basis of traditional politics from perspective of Merleau-Ponty's bodily phenomenology. In turn, alternatively I discuss Merleau-Ponty's basic idea of subjectivity. By drawing on his unique clarification of it, I approach and appreciate politics through the flesh. With the result of it, the embodiment of violence which is the permanent problem of politics is explained and disclosed distinctively. In conclusion, I might suggest what could be implicit in Merleau-Ponty's politics of flesh for Korean contemporary political issue i. I hope you relearn how to see political life in this paper.

The purpose of this study is to obtain a comprehensive understanding of shift nurses' mealtime experience on duty. This study was explored by hermeneutic phenomenological analytic method suggested by van Manen. The participants were shift nurses at two general hospitals in Korea. Six participants were interviewed until information reached saturation point. Data was collected through individual in-depth interviews. The results of study were emerged 7 themes. Each theme was :'Forgetting hunger.', 'Fatigue takes precedence over hunger.', 'Feeling sorry and becoming conscious of other colleagues.', 'Inhale the meal in a short time.', 'Conflicting between responsibility for the patient body and my body', 'They want look for freedom and right through their mealtime.', 'Hope that mealtime is a precious time.' The results of this study are significant in providing a convergence understanding of the working environment of the shift nurses.

Aging is divided into intrinsic aging and photo-aging. Intrinsic aging is naturally occurred as the time passed and photo-aging is induced by the UV radiation of skin. The main reason of aging is the free radicals and the degeneration of the cellular materials by free radicals. In this paper, we checked the anti-aging effects of Mallotus japonicus bark extracts. It has the ability to scavenge free radicals and the SOD like activity. Also, it reduced the cell damage by hydrogen peroxide treatment. Mallotus japonicus bark extracts showed the excellent activity on inhibiting the UV induced cell damage and DNA damage. In conclusion, Mallotus japonicus bark extracts can be used as active ingredients for anti-aging cosmetics.

It is incontestable that the essence of the current fever of well-being is pseudo-ideology, which is the commercialized well-being. Nevertheless, the potential value as the cultural contests of Korean Design, reaching the philosophy of well-being, must not be overlooked. Being more than its dictionary meaning of 'happiness' and 'welfare', well-being aims peace of mind and richness in mentality, thus supports the life style of 'Body-Mind Monism'. As a trend that has taken a ride on the consumerism, it is inevitable to excavate the benign cultural value that an ordinary sign of well-being lacks in order to create a peculiar model of Korea's design contents by sublimating the commodity aesthetic of well-being into an alternative argument possessing the cultural identity of Korea. Well-being, not much different form an attitude of following the 'ways of nature', is a typical model of non-dualistic thinking of East Asia. By tracing back to the indication of well-being that already existed in the non-dualistic thought and design of East Asia, the genealogy connecting the current phenomena of well-being to the Body-Mind Monism can be found in the cultural traditions of as close as Korea and as far as East Asia. In the case of adopting the monistic way of East Asian thinking that sees body and mind as one not two as the theoretical background of well-being imported fro the West, it is expected to provide a solution for the design discourse of Korea to be out of colonialism. Well-being contributes to the monistic awareness in the period of self-reflected modernization, which needs to search new values based on the reconsideration of dualistic paradigm centered on the Western culture, thus it is worth putting anticipation on the potential significance well-being would have in the field of national as well as international design world.

This paper begins with the question of whether "on-tact" Christian education, which has become the most new-normal phenomenon since Corona 19, will remain as a decisive form of Christian education even in the post-Corona era. In order to answer that question, this study explored whether on-tact Christian education has its own domain of experience and educational elements that cannot be replaced by face-to-face education, specifically focusing on "types of on-tact Christian Education", "discussion of digital church" and "digital epistemology". Through research on "types of onn-tact Christian education," it confirmed that, when viewed on the basis of 'participation' or 'communication', on-tact Christian education has an independent field of experience and educational elements. Through contemplation on "digital ecclesiology", it found that on-tact education is the decisive channel for Christian education to reach digital generation. It also found a new metaphor from the "network" concept for the public church and the Kingdom of God. This paper also found that we experience the perception of the body that is expanded through the combination between the body and technology in the digital world, and that this is a unique epistemology that occurs only in the digital world. Based on the above points, it affirmed that on-tact Christian education is not simply a means of supplementing face-to-face education in the era of COVID-19, but is a Christian education that has an independent field of experience and educational power that face-to-face education cannot replace. Thus it foresees that on-tact Christian education will continue to expand as a center and form of Christian education even in the post-corona era.
