Isolated sinus node cells of the rabbit were used to assess the effects of extracellular Na, K, Ca and Mg concentrations on cardiac pacemaker activity. With intracellular glass micro-electrodes spontaneous action potentials of SA node were recorded and the effects of various ions and their blockers were analyzed in terms of the cycle length, the amplitude and the duration of action potentials, the results obtained were as follows. 1. Sodium reduction [up to 30%] decreased the amplitude of action potential and lengthened the cycle length. TTX, specific blocker of Na channel slightly lengthened the cycle length. 2. Increasing potassium ion concentration, the duration of action potential decreased and the frequency increased in 6mM, however, spontaneous action potential was stopped in 24 mM. Barium ion known to be decreasing K conductance increased the duration of action potential but no significant change in the cycle length was noticed. 3. Calcium ion has shortening effect on the duration and the cycle length of action potential but not with dose-dependent manner. Cadmium ion .[0.02mM] lengthened cycle length and the duration of action potential. 4. Increasing the concentration of magnesium ion the cycle length was lengthened, significantly.

5-Hydroxytryptamine(5-HT, serotonin), when given into the vein, produced antidiuretic action accompanied with reduction of glomerular filtration(GFR), renal plasma flow(RPF), osmolar clearance(Cosm) and amounts of sodium or potassium excreted in urine( $E_{Na}$ , $E_{K}$), with the augmented reabsorption rates of sodium and potassium in renal tubules. 5-HT, when infused into a renal artery, exhibited diuretic action accompanied with the augmented RPF and increased $E_{Na}$ and $E_{K}$ in only infused kidney. Antidiuretic action of 5-HT infused into the vein was not influenced by ketanserin, 5-H $T_2$receptor blockade, given into a renal artery, vein or carotid artery, by methysergide, 5-H $T_1$receptor blockade, given into a renal artery, whereas above antidiuretic action was inhibited by methysergide given into vein or carotid artery. Diuretic action of 5-HT infused into a renal artery in only experimental kidney was blocked by ketanserin injected into a renal artery, was not influenced by methysergide administered into a renal artery. Above results suggest that 5-hydroxytryptamine(5-HT) produced the antidiuretic action through central 5-H $T_1$receptor and the diuretic action through 5-H $T_2$receptor located in renal tubules of kidney.ney.

최근 행위 개념의 신경적 표상에 대한 fMRI나 EEG 연구들은 행위 개념의 처리가 감각-운동 정보의 모사(simulation)를 불러일으킨다고 주장한다. 이와 아울러 행위동사나 행위 문장 이해가 현재 수행해야 하는 행위를 간섭하거나 촉진시킨다는 행동연구들도 존재한다. 그러나 행위 개념 처리와 현재 행동 수행간의 실시간 상호작용이 감각-운동정보의 모사를 매개로 하는지, 또 다른 기전에 바탕을 두는지 아직까지 분명하지 않다. 본 연구에서는 행위 언어 지각이 어떻게 현재 행위 수행에 영향을 주는지 그 기저에 있는 신경 메커니즘을 시공간적으로 탐색하고자 시간해상도가 높은 뇌파 측정과 다중전류원분석이라는 뇌파분석 기법을 사용하였다. 이를 위하여 실험참가자에게 단서 자극 색상에 따라 손으로 버튼 누르기 행동과 발로 페달 밟기 행동을 해야 하는 단서-운동반응 과제를 수행하도록 하였고, 단서가 제시되기 직전에 반응 행위자체를 기술하는 행위동사(즉, 눌러라, 밟아라, 멈춰라)를 청각적으로 제시하여 행위동사와 반응 행동 간의 의미 일치성에 따른 상호작용을 관찰하였다. 반응시간 분석 결과, 손으로 버튼을 누르는 반응행위와 발을 이용하여 페달을 밟는 반응행위 모두에서 행위동사와 반응행위가 일치하는 경우 촉진효과가 관찰되었고, 불일치에 따른 간섭효과는 손 행위에서 나타났다. 전류원 파형 분석결과, 행위동사와 반응행위간의 의미일치성 효과는 행위 동사 처리 기간에는 베르니케 영역, 운동단서 제시 시점에선 전대상회와 보조운동영역, 운동수행 시점에서는 보조운동영역과 일차운동피질에서 통계적으로 유의한 차이가 관찰되었다. 현재 결과로는 행위동사가 특정 운동피질을 활성화시켜 이를 매개로 현재 행위에 영향을 준다고 하기보다, 뒤따르는 행위를 예측하고 이를 준비하는 과정에 영향을 미쳐, 촉진/간섭효과를 가져오는 것으로 보인다. 마지막으로 본 연구가 가지는 행위 개념의 신경학적 표상에 대한 함의와 연구 방법론상 한계에 대해 논의하였다.

Action Time이란 탄이 공이가 뇌관을 격발한 순간부터 총구를 이탈할 때까지의 걸리는 시간을 말한다. 40mm 고속유탄은 장전되면서 격발되는 구조이므로 Action Time이 특정 시간 이내여야 탄피 고착과 같은 악작용을 방지 할 수 있다. 기존 40mm 고속유탄의 Action Time 계측은 신뢰성 있는 측정 장비의 부재로, 그동안 Action Time이 K4기관총 품질 보증에 적용되는 것에 어려움이 있었다. 본 연구에서는 다양한 센서 간 비교와 별도의 발사 장치 고안을 통해 정확한 Action Time을 측정하고자 하였다. 이 장치에서는 공이 부분에 설치된 광센서의 신호와 총열 부분에 설치된 와전류 탐촉자 신호 간 간격이 계측되고, 실시간으로 컴퓨터로 데이터가 전송되게 된다. 계측된 Action Time 결과가 시스템 요구 성능에 충족하는지 여부를 즉시 확인함으로써 40mm 고속유탄의 품질 보증에 중요한 역할을 할 것으로 기대된다.

Enforcement Decree of the Framework Act on Low Carbon, Green Growth for achieving the country's GHG emission reduction goal of 30% was in effect. The remarkable content of the Act is the managements of targets for GHG reduction. So, the entities that have reduced voluntarily have much interest in the recognition of 'early action'. The recognition of early action is necessary to induce the fair competence of business entities and promote the voluntary GHG reduction. The definite and concrete guidance should be prepared. The important principles for this are the environmental integrity and the additionality. Based on this, the early action activities must be restricted to the voluntary, real, permanent, quantifiable, verifiable reduction. In the early action recognition, its credit should be allocated additionally set aside from the GHG target allocation in the national total allowance. Through this, the reward for the early reduction should be realized on market mechanism. The effective period to award the early action should be addressed. This can be the period after the enactment of framework on GHG reduction in effect and before the beginning year of GHG target control. It should be set with flexibility through the collection and consultation of the sector's opinions. The appropriate allowance reserve of early action was estimated as approximately 1~1.5% by using the data from the 'Pilot GHG Emission Trading Program' operated by Ministry of Environment. Also, the concrete and detail guidance to construct the necessary infra which is used to register the related information of early action activities should be prepared.

Dopamine mediates inhibitory responses in Helix aspersa neurons from the right parietal lobe ("F-lobe") of the circumoesophageal ganglia. The effects appeared as a dose-dependent hyperpolarization of the plasma membrane and a decrease in the occurrence of spontaneous action potentials. The average hyperpolarization with 5 ${\mu}m$ dopamine was -12 mV (${\pm}1.5$mV, S.D., n=12). Dopamine also modulated the currents 'responsible for shaping the action potentials in these neurons. When dopamine was added and action potentials were triggered by an injection of current, the initial depolarization was slowed, the amplitude and the duration of action potentials were decreased, and the after-hyperpolarization was more pronounced. The amplitude and the duration of action potential were reduced about 15 mV and about 13% by 5 ${\mu}m$ dopamine, respectively. The effects of dopamine on the resting membrane potentials and the action potentials of Helix neurons were dose-dependent in the concentration range 0.1 ${\mu}m$ to 50 ${\mu}m$. In order to show 1) that the effects of dopamine were mediated by dopamine receptors rather than by direct action on ionic channels and 2) which type of dopamine receptor might be responsible for the various effects, we assayed the ability of mammalian dopamine receptor antagonists, SCH-23390 (antagonist of D1 receptor) and spiperone (antagonist of D2 receptor), to block the dopamine-dependent changes. The D1 and D2 antagonists partially inhibited the dopamine-dependent hyperpolarization and the decrease in action potential amplitude. They both completely blocked the decrease in action potential duration and the increase in action potential after-hyperpolarization. The dopamine-induced slowdown of the depolarization in the initial phase of the action potentials was less effected by SCH-23390 and spiperone. From the results we suggest 1) that Helix F-lobe neurons may have a single type of dopamine receptor that binds both SCH-23390 and spiperone and 2) that the dopamine receptor of Helix F-lobe neurons may be homologous with and primitive to the family of mammalian dopamine receptors.
