The subject is connected with a structure named "The Symbolic" to Lacan, but he denied that the subject is explained simply as a fruit of language and "Other". From his point of view, passing through Subject, De-formation and Crack over it is designated as foundation of generation and creation rather than our destined defect. It should not be understood that subject of "The Real" is a concept of the subject free itself from restraint of "The Symbolic". However, this does not mean he asserts "Subject" is something incapable of being controlled by the unknown power. The problem is that this autonomous existence meets inside of it with something "more than one's own self" by "circulating around itself" like a permanent star. This is the indication of a "stranger in the middle of my privacy", or "extimit$\'{e}$", a coined-word by Lacan. Perhaps "Subject" is nothing more than the name of distance of object which is "too hot" to come close, and of this circulating movement. It's because of this object that the real subject stands against generalization and the subject can't be restored to any place in symbolic order-even though it is empty. The part which is told from Lacan's structural theory, that is to say, an importance to Lacan is that his Subject theory is not suggested or denied as a manual structure. On the contrary, it is a study of the relationship between the settled symbol that included in "real subject which is a unconscious one" and the symbolic subject hold- that is a metaphysical subject in general meaning. In Lacan's enlarged concept of subject beyond symbolic reality, it is noticeable that it gives justifiability to the union of a medium of different nature in artistic expression. We can recognize that the unconscious world is a living space which enables it to be a "condition of human being", not something dark under the surface of water through Magritte's(Rene Magritte, 1898~1967) surrealistic works. In other words, Magritte's art secures a core dimension of human nature through a mysterious gap of conscious and settled space. Magritte's drawings often evokes strange and unsettling feelings in people who view his paintings. This is because routine objects are found in "unsuitable" places from which we usually find them in our everyday lives. "Reality" in Magritte's paintings makes it aware that it is a strained field of concealment and disclosure basically between truths, and we can learn that his behavior to overturn to paint in-visible things is finally an effort to restore the "real subject" to the viewer's reality. In other words, such reversion arouses a nostalgic desire for the objects existing in their original appearance as they are - natural condition that our gaze had not been distorted yet by anamorphic stains. - and the state when we are conscious of them normally. Such desire offers an opportunity for us to get out of mental depression rather than operates to us as an abnormal crack. It's a successive process of effort to search for lost subject and Paradise Lost facing up to reality of subject human that is to be a subject of world and life are ousted from their place by structure and authority of culture.

본 연구에서는 생태모방적 관점에서 목질을 천공하는 송곳벌과 밑드리좀벌의 산란관의 형태적 특징을 비교하였다. 벌목에 속하는 송곳벌과 밑드리좀벌은 목질부를 천공하는 유사한 특징이 있으나 실체현미경, 전계방사형주사전자현미경, 광학현미경을 이용하여 산란관의 형태적 특징을 관찰한 결과 두 종 간에 큰 차이를 보였다. 송곳벌의 산란관 말단은 등쪽과 배쪽에 모두 규칙적인 돌기가 발달하여, 회전형 드릴 비트와 흡사한 형태를 띤 반면 밑드리좀벌의 산란관 말단은 한쪽 방향에만 몇 개의 돌기가 있고 다른 부분은 매끄러워 마치 톱과 비슷한 형태를 보였다. 또한 얼룩송곳벌 산란관의 말단은 대칭적으로 4등분으로 되어있다가 14번째 돌기를 지나면서 2 : 1 : 1의 비율로 3등분이 되는 반면, 밑드리좀벌 산란관의 말단은 2 : 1 : 1의 비율로 3등분되어 있음을 확인할 수 있었다. 또한, 송곳벌의 산란관의 중간을 수평으로 자른 단면구조에서는 dovetail joint의 구조가 확인되었으며, 이를 통해 천공을 위해 수직 운동을 한다는 것을 확인할 수 있었다. 이러한 두 종의 형태적 차이는 목질 부분을 먹이원으로 이용하는 송곳벌과 벌의 유충을 이용하는 밑드리좀벌의 생활방식뿐만 아니라 계통분류학적 차이에 의해 기인한 것으로 사료된다. 끝으로, 산란관 말단 부분의 성분분석결과 두 종 모두에서 높은 강도의 특성을 부여하는 아연이 검출되었다. 이는 주로 목질을 천공하는 두 종의 생태적 적응 과정에 의하여 특이적으로 진화된 것으로 사료된다.

Purpose : The aim of this study was to investigate the effects of stepper exercise using lower extremity patterns of PNF(Proprioceptive neuromuscular facilitation) on ankle muscle strength and balance ability of females in their twenties. Method : Twenty subjects participated in this experiment were carried out the exercise program dose of 5 days per week for 2 weeks. They were divided into two groups; using twist stepper group(lower extremity patterns of PNF group, n=10) and using straight stepper group(n=10). The effects of twist stepper and straight stepper were evaluated by measurements of normal standing(NSEO, NSEC), and dynamic type 1 and dynamic type 2, respectively. For each case, the experimental data were obtained about static balance in 3 items : mean X speed, mean Y speed and velocity moment, that of dynamic balance in 4 items : mean X speed, mean Y speed, time, distance. Results : The results of this study were as follows; 1) In straight stepper group, the statistically significants were significants were shown on right/left ankle muscle strength in case of dorsi-flexion. 2) In twist stepper group, the statistically significants were significants were shown on right/left ankle muscle strength in case of dorsi-flexion. 3) In straight stepper group, the statistically significants were significants were shown on right ankle muscle strength in case of plantar-flexion. 4) In twist stepper group, the statistically significants were significants were shown on right/left ankle muscle strength in case of plantar-flexion. Conclusion : The above results revealed that twist stepper exercise using lower extremity patterns of PNF was more effective than straight stepper exercise for improving the ankle muscle strength.

19세기 말, 영화와 함께 등장한 애니메이션은 모더니즘이라는 예술사적 양식을 자양분으로 삼아 등장한 매체였다. 하지만 애니메이션과 모더니즘의 관계 설정은 주로 애니메이션의 형상들, 즉 그려진 이미지에 집중되어 왔다. 이는 애니메이션과 회화의 관계를 설명하는 것으로부터 기인한 것이었는데, 이 때문에 애니메이션에서의 움직임의 논의는 머이브릿지와 쥘 마레의 연속사진술(chromophotograph)의 전통, 또는 실사영화(live-action film)가 가진 몇 가지의 특질 속에서만 이해하였다. 그러나 애니메이션의 움직임은 기본적으로 영화나 포토그램의 지표기호적 양식(indexical style)과는 거리가 멀었으며, 재현의 대상도 달랐다. 애니메이션이 재현하는 움직임은 일상적인 움직임이 아닌, 추상화 되거나 압축된 움직임의 표현이자, 상당히 체계화된 움직임이다. 때문이 이러한 움직임은 실사영화의 포토그램적 재현과는 거리가 있다. 오히려 애니메이션에서 재현하는 움직임의 논리는 신체를 각 부분을 분할한 후, 그것들의 가동범위와 시간, 거리 등으로 통제하는 것에 가깝다. 이것은 인간 신체를 교환가능한 기계로 구성하고 파악하려 하였던 - 데카르트와 라메트리로 대표되는 - 근대 기계론의 입장으로 귀결된다. 근대사회로부터 산업사회, 그리고 모더니즘의 시기에 까지 이르는 근대 기계론의 기획은 자연으로서의 움직임이 아닌, 자연 법칙으로서의 움직임으로 파악하면서 효율적인 움직임의 구성이라는 근대 산업사회의 신체 움직임 분석에 까지 이르게 된 것이다. 19세기 말, 테일러(Taylor, F. W.)와 길브레스(Gilbreth, Frank Bunker)의 노동자 작업 시간 연구와 '동작연구'(motion study)는 기계-인간의 틀을 구성하는 근대적 방식이었는데, 이는 근대 기계론의 전통이 산업사회를 지나 모더니즘 전반에 영향을 끼쳤음을 알 수 있다. 더 나아가 이들이 진행한 동작연구들은 이후 애니메이션이 '타이밍'이라는 이름으로 연구하였던 행동분석(action analysis)과 거의 유사한 특성을 가지고 있음을 알 수 있다.

In the primary sensory neuron of the mesencephalic trigeminal nucleus (MTN), the peripheral axon supplies a large number of annulospiral endings surrounding intrafusal fibers encapsulated in single muscle spindles while the central axon sends only a few number of synapses onto single ${\alpha}-motoneurons({\alpha}-MNs)$. Therefore, the ${\alpha}-{\gamma}$ linkage is thought to be very crucial in the jaw-closing movement. Spike activity in a ${\gamma}-motoneuron\;({\gamma}-MN)$ would induce a large number of impulses in single peripheral axons by activating many intrafusal fibers simultaneously, subsequently causing an activation of ${\alpha}-MNs$ in spite of the small number of synapses. Thus, the activity of ${\gamma}-MNs$ may be vital for modulation of jaw-closing movements. Independently of such a spindle activity modulated by ${\gamma}-MNs$, somatic depolarization in MTN neurons is known to trigger the oscillatory spike activity. Nevertheless, the trafficking of these spikes arising from the two distinct sources of MTN neurons is not well understood. In this short review, switching among multiple functional modes of MTN neurons is discussed. Subsequently, it will be discussed which mode can support the ${\alpha}-{\gamma}$ linkage. In our most recent study, simultaneous patch-clamp recordings from the soma and axon hillock revealed a spike-back-propagation from the spike-initiation site in the stem axon to the soma in response to a somatic current pulse. The persistent $Na^+$ current was found to be responsible for the spike-initiation in the stem axon, the activation threshold of which was lower than those of soma spikes. Somatic inputs or impulses arising from the sensory ending, whichever trigger spikes in the stem axon first, would be forwarded through the central axon to the target synapse. We also demonstrated that at hyperpolarized membrane potentials, 4-AP-sensitive $K^+$ current ($IK_{4-AP}$) exerts two opposing effects on spikes depending on their origins; the suppression of spike initiation by increasing the apparent electrotonic distance between the soma and the spike-initiation site, and the facilitation of axonal spike invasion at higher frequencies by decreasing the spike duration and the refractory period. Through this mechanism, the spindle activity caused by ${\gamma}-MNs$ would be safely forwarded to ${\alpha}-MNs$. Thus, soma spikes shaped differentially by this $IK_{4-AP}$ depending on their origins would reflect which one of the two inputs was forwarded to the target synapses.

2011년 3월 일본 동북지방의 태평양 연안 해저에서 발생한 거대 지진(M 9.0)에 의한 쓰나미 재해와 지각변동에 대하여 조사하였다. 센다이 해안 평야의 경우 쓰나미에 의한 침수 거리는 현 해안으로부터 4.0km에 달하였다. 쓰나미 사질 퇴적물은 쓰나미 침수범위 중의 바다쪽 60~75%의 구간, 니질 퇴적물은 육지쪽 25~40%의 구간에 분포한다. 이 분포 비율은 센다이 해안평야의 충적층 속에 묻혀있는 과거 거대 쓰나미 때의 퇴적물 분포로부터 당시의 내륙쪽 침수한계를 추정하는데 활용될 수 있을 것으로 보인다. 센다이 해안평야 지역에서는 표고가 낮고 저평한 지형조건이, 그리고 리아스식 해안인 산리쿠 해안지역에서는 좁은 만입부에서의 쓰나미 증고 현상이 쓰나미 재해를 크게 증대시킨 요인으로 작용하였다. 이시노마키, 오가와, 오가치, 오나가와 등 동북 일본 해안지역의 여러 곳에서 이번의 대지진으로 인한 지각변동으로 0.5~1.0m정도의 지반침강이 일어났음을 확인하였다.
