The following conclusion has been derived from the foregoing results of analysis and observation. First, we found, in this proposed system, reliability, objecivity, and individuality. Second, this type of system must be able to measure numerable testees. Third, testees are regulated that they are brought to the same condition in which their willful adventage are not allowed, Fourth, when considering the foundamental physical strength and skills can be evaluated in general throughout all skills areas of physical education, the following items of skills are recognized to have the advantages and disadvantages which relatively lack or relieve one another. However, under various conditions of the prevailing system of the entrance physical test, the following measurable items of physical skills selected are concluded as having highest validity primarily for the physical entrance examination. 1. Side Step B Style 2. Zigzag Run 3. Wall Pass 4. Standing Long Jump

體育活動을 通한 새마을 運動의 成果 擧揚 方案 : 새마을 農民體操 創案을 中心으로 Centering around creative Saemaul Farmer's Exercises

金正默,金基學,申榮吉 慶北大學校 師範大學 1979 敎育硏究誌 Vol.21 No.-

The research is pertinent to the actual health conditions of farmers in this country. Among the diseases from which they suffer are those involving stomach, spinal column, shoulders, and the lower limbs. For that matter, the Saemaul Farmer's Exercises are made up with the goal of refreshment, preventive correction and distraction as well. Futhermore, the exercises of the total body aim at making progress in physical strength. The exercises consist of thirteen different motion; the movements are done in two-dimension, these exercises are for both begginers and for skillful people. The frequency of repeating motions becomes different according to sex, and physical strength. Ustally sixteen respiratory intervals are for the weak, the old, and females; thirty-two respiratory intervals are used by the strong and young, predominatly by male. The exercises themselves have flexibility which makes it possible for individuals to increase or reduce the amount of motion. There are thirteen kinds of movements in the following order: 1) Stretching up 2) Bending and Swinging neck 3) Twisting and Revolving Arms 4) Widening, Bending, and Straightening Limbs 5) Stretching Arms while Tightening Chest Muscular 6) Side Stretching 7) Stretching Body Back and Forth 8) Twisting from side to Side 9) Lifting Thighs in turns and Turning Waist Over 10) Twisting and Stretching Body Back and Forth 11) Jumping on Tiptoe and Hopping 12) Lifting heels and Putting Weight of Body on Toes 13) Controlling Breath, both Inhaling and exhaling

筋의 生理的 收縮에 關한 考察 : Training을 中心으로 Chiefty on Training

金正默 慶北大學校 師範大學 1978 敎育硏究誌 Vol.20 No.-

1. There are three types of muscle contraction; Concentric, eccentric, and isometric Contraction. Concentric contraction is the action to contract muscle by shortening it. And both the actions belong to istonic contraction which is a kind of dynamic contraction. The other is isometric contraction, belong to static contraction, which is the action to contract muscle without changing its length. But isometric contraction is thought to be devided into concentric and eccentric contraction. These two actions seem to be similar because there is no apparent change in the length of muscle contraction, but they are different from each other, in that the first is substantially based on flexor (shortening muscle), the second on extensor(lengthening muscle). And so both the muscle groups must be equally exercised in training physical strength; Otherwise physical strength will not be equally balanced. As a result, it is believed that muscle contraction is divided into four types: two in isotonic contraction, the others in isometric contraction. And muscle training is supposed to be carried out effectively with these four types of muscle contraction. The above is diagrammed as follows: ◁그림 삽입▷(원본을 참조하세요) 2. There are two ways of contracting muscle in isometric contraction. One is isometric lengthening which makes concentric into eccentric contraction by compulsory measures. The other is isometric shortening, concentric contraction. The former, which is estimated to be more powerful than the latter by 20-30 percent, consequently it settles ploblem betwen grip strength and back strength, is expected to play an important part in the actual training of physical strength. But it is. far from my suggestion here. My suggestion is that, not by compulsory measures but by voluntary measures, concentric contraction should be transformed into eccentric contraction. 3. In strengthening muscular power, we are mostly dependent upon weight training, widely used up to now, which is the way of isotonic training. But here are several ploblems involved: the relation with speed, the effect on muscle groups, and the combination of eccentric training with concentric training. And in the way of isometric training there are also some problems involved: the relating between concentric training and eccentric training, how to arouse the trainer's interest, and the invisible outward aspect of motions in muscle. Consequently, it is believed that the most effective way of training muscle will be realized, by compensating for the weakness of isotonic training with the help of isometric training and vice versa.

In this report, gastric analysis, fasting serum gastrin and secretin concentration had been carried out in 45 cases of primary gapatoma and 54 cases of postnecerotic liver cirrhosis. Higher levels of gastric acid and papsin output, increment of gastric acid output and trtragastrin-stimulated volume rate were observed in primary hapatoma and postnecrotic liver cirrhosis with peptic ulcer than in those without peptic ulcer. In conclusion, in was suggested that gastric and pepsin might play an important role in peptic ulcer formation in primary gapatoma and postnecrotic liver cirrhosis and that the manner of gastric secretion and mechanism of ulcer formation in peptic ulcer without liver disease might be different from those of liver disease with peptic ulcer.

맨손 체조의 一硏究

The Free Exercises was designed artificially. So it should answer the purpose of enhancing the softness, flexibility and mobility of our muscles and joint regions at every exercise. In this respect, it differs from other sports and games which use instruments and whose main, aims are for entertainment, even if it started from the need of our daily life with them. It is true that these sports and games produce good effect on body as a whole. But some parts of them are barely effective on our body, and sometimes even harmful. On the other hand, in the Free Exercises the swinging of hands, the bending of knees, the bowing of body, almost every motion has its own object and helps develop our body and mind directly. It is probable that in practicing the Free Exercises we follow the order and the way of exercises our predecessors had fixed, without critical examination. Here arises the need of re-examining it on the dynamic and antomic foundation, I have studied some important and needful points in the exercises of legs, neck, arms, chest, flanks, back, abdomen and body here. The conclusion is: 1. All exercises must have a process developing the flexibility of joint regions and the softness of muscles by .bringing the big muscles into extreme action. 2. Avoid the duplicatiin of exercises which practice the same muscles and joint regions, though their names are different. 3. We gain the strongest power and speed when the movement of the center of gravity harmonizes with the exercises of arms. 4. The swinging and turning of hands, which help the other parts of our body when we practice exercise, must be used properly. 5. It is necessary to take correct poses to balance our body, but it is also necessary to develop the speedy and effective way of taking balance from an unbalanced position. 6. A systematic practice of rebounding increases the softness of action with rhythmicality. 7. It is necessary to vary the way of exercises one by one, for example, the swinging of hands, the bending of knees, turning of course and changing of stability.

Studies on the Integral Protein Form of Choline Acetyltransferase from Squid Ganglia Membrane

오징어 머리의 신경절로부터 회수된 synaptosome을 반복된 저 삼투압에 의한 파열과 100 mM $KH_2PO_4$ 완충용액(pH 6.8)에서 초원심분리하여 synaptoplasm에 용해된 choline acetyltransferase(ChAT)와 막에 비이온적으로 결합된 막 내부 ChAT를 분리하였다. 막 내부 ChAT의 효소 활성은 synaptosome으로부터 회수된 전체 ChAT 활성의 약 20%를 차지하였다. 높은 acetylcholine 농도에서 용해된 형의 효소활성이 막 내부 형보다 훨씬 높은 정도로 저해되었으며, calcium 농도를 10 mM에서 100 mM로 증가시킴에 따라 용해된 형과 막 내부 형의 효소활성은 유사한 형태로 감소하였으나 용해된 형의 효소활성이 전체적으로 막 내부 형보다 덜 저해되는 것으로 나타났다. 2.0 mM SDS 농도에서 용해된 형의 효소활성은 완전히 소실되었으나 막 내부 형은 3.0 mM SDS 농도에서 기준점 효소활성의 약 74%를 가지고 있었다. 용해된 효소와 막 내부형 효소는 최적 pH가 6.6이어서 같았으나 전자의 profile은 좁은데 비해 후자는 현저히 넓었다. 용해된 형과 막 내부형의 최적 온도는 공히 $32^{\circ}C{\sim}35^{\circ}C$이었으나 $35^{\circ}C{\sim}56^{\circ}C$ 영역에서 막 내부형이 용해된 형보다 안정하였다. Acetyl-CoA에 대한 $K_m$ 값은 용해된 형과 막 내부형 공히 0.12 mM이었다. 이러한 결과들은 오징어 머리의 신경절에 choline acetyltransferase의 막 내부형이 존재한다는 것을 시사한다. The membrane-embedded form (integral membrane protein) of the choline acetyltransferase (EC 2.3.1.6) was prepared from squid head ganglia. The preparation procedure includes repeated hypo-osmotic disruption and washing by ultracentrifugation in a high ionic strength buffer. It appears that approximately 20% of the synaptosomal choline acetyltransferase is present as an integral protein, non-ionically bound to membrane. It was found that at high concentrations, the acetyl choline (ACh) inhibits soluble ChAT to a greater degree than the membrane-embedded form. The activities of soluble and membrane-embedded ChAT also decrease with increasing calcium concentration but the activity of soluble ChAT is inhibited less than that of membrane-embedded ChAT. The activity of soluble ChAT is completely lost at 2.0 mM SDS concentration whereas the membrane-embedded ChAT still exhibits about 74% of the control value at 3.0 mM SDS concentration. Soluble ChAT exhibits a sharp pH optimum near 6.6 in potassium phosphate buffer whereas membrane-embedded ChAT shows a broader pH-activity profile. Optimum temperature of both soluble and membrane-embedded forms of ChAT is $32{\sim}35^{\circ}C$ but over the range of $35{\sim}56^{\circ}C$, the membrane-embedded ChAT is more stable than the soluble enzyme. Soluble and membrane-embedded forms of ChAT exhibit identical $K_m$ values of approximately 0.12 mM for the substrate of acetyl-CoA. These results strongly indicate that two different forms of ChAT, one soluble and one membrane-embedded, are present in squid head ganglia.
