As a nursing practice involves nurses' actions in a specific context of health care, this study has focused on exploring the espoused theories in nursing practice within the action science perspectives, Espoused theories are the belief, principles, and rationale expressed by the practitioner as guiding her/his actions in a situation of practice. The data were analysed qualitatively and 25 elements of espoused theories of nursing action were identified and clustered into 6 categories. The 25 elements of espoused theories are as follows: The clinical nurse worked in wholistic and individual nursing, focussed on the patient's needed, comfort and supportive nursing (5 theories of nursing goal) ; excellent skills, knowledge based, assessment and data collection, explaining, educating or a scientific basis(6 theories of nursing intervention): advocacy, value oriented, treatment, account- ability and commitment(4 theories of nursing ethics) ; human respect. partnership, trust(3 theories of patient-nurse relationship) : knowledgable, accumulated clinical experiences and personally lived experiences. positive perspectives(4 theories of nurse), role of intervention. rewarding peer relationship(3 theories of situations) The above mentioned espoused theories are similar to that of nursing textbooks which students learned through basic nursing education and almost the same as the Acts ofa Nurse in Korean. However, we are doubtful whether nurses actually do as they think. Therefore. it is recommended to review the theories-in-use in order to and any discrepancies between the espoused theories and the reality of nursing actions

For the development of seedling production techniques of the freshwater crab Eriocheir japonicus, the effects of salinity and temperature on the growth of larvae of the crab were studied. Embryos hatched out as zoea larvae were measured 0.421 mm in average carapace length. Five zoea stages needed 16~26 days for metamorphosis from zoea to megalopa at 22℃ and 24.5‰. The average carapace length of the 5th zoea was 1.16 mm and that of the megalopa larvae was 1.89 mm. Each zoea stage could be identified based on both the number of plumosed seatae on the exopodite of maxilliped, and the number of spines on the posteroinner margin of telson and also based on the rudimentary pleopods appearence. Zoea larvae fed rotifers and Artemia nauplii were healthy and metamorphosing rate from zoea to megalopa was 80~90% at 22~26℃ and 17.5~31.5‰. The relationship between larval period(Y in days) and water temperature (X in ℃) is expressed as Log Y=3.8604-1.91735 Log X. Water temperature and salinity ranges for better survival and metamorphosis of the larvae was 22℃~26℃ (optimum at 26℃) and 17.5‰~31.5‰(optimum at 24.5‰), respectively. The duration of larval stages tend to longer as salinity levels deviated from optimum particulaly at lower porendtion. All zoea larvae did not survive in freshwater

In order to study the optimum environmental condition for larvae culture of the freshwater crab, Eriocheir japonicus, larvae from different growth stages and young crab were cultured under the 16 different conditions of 4×4 temperature-salinity combinations (4 different temperatures at 22, 24, 26, 28℃ with 10.5, 17.5, 24.5, and 31.5‰ of salinity). The duration of metamorphosis, metamorphosis rate, the interval of. moulting period, and survival rate were measured from each experimental group of larvae and young crab under the different conditions. The results indicated that the optimum condition may be a 24.5‰ of salinity at water temperature at 22, 24, and 26℃. At 28℃ with 24.5‰, the duration of metamorphosis reduced somewhat, nevertheless metamorphosis and survival rate decrease a lot. And the lower the salinity showed the lower the metamorphosis and survival rates at 28℃.

이복규,김병기,권진수 동의대학교 기초과학연구소 2000 基礎科學硏究論文集 Vol.10 No.1

In the giant freshwater prawn Macrobrachium rosenbergii, the paired tests were united by the testes bridge in a H-shape. During mating male discharged two hemispermtophores from right and left genital pore and they were joined and formed a compound spermatophore in peach shape. Hemispermatophore was considered to be produced at proximal and middle vas deferens region. The compound spermatophore consisted of an eosinophilic inner matrix, a basophilic outer matrix and paired sperm mass burried in the basophilic matrix. The size of compound spermatophore was 6.4∼9.3 mm in length and 2.4∼5.1 mm in width regardless of carapace length. After the spermatophore was deposited on female's ventral sternum behind of 5th pereiopod, it was moved to the ventral surface of 3rd and 4th pereiopods by means of the beating of male's 1st and 2nd pleopods.

淡水産 새우, Macrobrachium nipponense (De Haan)의 增·養殖에 關한 生物學的 基礎硏究 : 2. Life History and Seedling Production 2. 生活史 및 種苗生産에 關한 硏究

權晉洙,李福奎 동의대학교 기초과학연구소 1993 基礎科學硏究論文集 Vol.3 No.1

Life cycle and seed production of the freshwater prawn, Macrobrachium nipponense, were studied and the results are as follows: 1. Larval development : Embryos hatched out as zoea larvae of 2.06 ㎜ in mean body length. The larvae passed through 9 zoea stages in 15∼20 days and then metamorphosed into postlarvae measuring 5.68 ㎜ in mean body length. Each zoea stage can be identified based on the shapes on the first and second antennae, exo- and endopodites of the first and second pereiopods, telson and maxillae. 2. Environmental requirements of zoea larvae : Zoea larvae grew healthy when fed with Artemia nauplii. Metamorphosing rate was 65∼72% at 26∼28℃ and 7.85∼8.28‰Cl. The relationship between the zoeal period (Y in days ) and water temperature (X in ℃) is expressed as Y=46.0900-0.9673X. Zoeas showed best survival in a water temperature range of 26∼32℃ (optimum temperature 28℃), at which the metamorphosing rate into postlarvae was 54∼72%. The zoeas survived more successfully in chlorinity range of 4.12∼14.08‰Cl. (optimum chlorinity 7.6∼11.6‰Cl.), at which the metamorphosing rate was 42∼76%. The whole zoeal stages tended to be longer in proportion as the chlorinity deviated from the optimum range and particularly toward high chlorinity. Zoeas at all stages could not tolerate in the freshwater. 3. Environmental requirements of postlarvae and juveniles : Postlarvae showed normal growth at water temperatures between 24∼32℃ (optimum temperature 26∼28℃). The survival rate up to the juvenile stage was 41∼63%. Water temperature below 24℃ and above 32℃ resulted in lower growth, and postlarvae scarcely grew at below 17℃. Cannibalism tended to occur more frequently under optimum range of temperatures. The range of chlorinity for normal growth of postlarvae and juveniles was from 0.00 (freshwater) to 11.24‰Cl., at which the survival rate was 32∼35%. The postlarvae grew more successfully in low chlorinities, and the best growth was found at 0.00∼2.21‰Cl. The postlarvae and juveniles showed better growth in freshwater but did not survive in normal sea water. 4. Feeding effect of diet on zoea llarvae : Zoea larvae were successfully survived and metamorposed into postlarvae when fed commercial artificial plankton, rotifers, and Artemia nauplii in the aquaria. However, the zoea larvae that were fed Artemia nauplii and reared in Chlorella mixed green water showed better results. The rate of metamorphosis was 68∼75%. The larvae fed cow liver powder, egg powder, and Chlorella alone did not survive. 5. Diets of postlarvae, juveniles and adults : Artemia nauplii and/or copepods were good food for postlarvae. Juveniles and adults were successfully fed fish of shellfish flesh, annelids, corn grain, pelleted feed along with viscera of domestic animals or fruits. 6. Growth of postlarvae, juveniles and adults : Under favorable conditions, postlarvae molted every five or six days and attained to the juvenile stage within tow months and they reached 1.78 ㎝ in body length and 0.l7 g in body weight. The juveniles grew to 3.52 ㎝ in body length and 1.07 g in body weight in about four months. Their sexes became determinable based on the appearance of male's rudimental processes (a secondary sex character) on the endopodites of second pereiopods of males. The males commonly reached sexual maturity in seven months after attaining the postlarvae stage and they grew to 5.65 ㎝ in body length and 3.41 g in body weight. Whereas the females attained sexual maturity within six to seven months, when they measured 4.93 ㎝ in body length and 2.43 g in body weight. Nine or ten months after hatching, the males grew 6.62∼7.14 ㎝ in body length and 6.68∼8.36 g in body weight, while females became 5.58∼6.08 ㎝ and 4.04∼5.54 g. 7. Stocking density : The maximum stocking density in aquaria for successful survival and growth was 60∼100 individuals/ℓ for zoeas in 30-days rearing (survival rate to postlarvae, 73∼80%) ; 100∼300 individuals/㎡ for postlarvae of 0.57 ㎝ in body length (survival rate for 120 days, 78∼85%) ; 40∼60 individuals/㎡ for juveniles of 2.72 ㎝ in body length (survival rate for 120 days, 63∼90%) ; 20∼40 individuals/㎡ for young prawns of 5.2 ㎝ in body length (survival rate for 120 days, 62∼90%) ' and 10∼30 individuals/㎡ for adults of 6.1 ㎝ in body length (survival rate for 60 days, 73∼100%). The stocking density of juveniles, youngs and adults could be increased up to twice by providing shelters.

Ca^(2+)-감수성 증가기전과 평활근 수축

이연리,김보경,최원호,김태경,이창권,배영민,조성일 건국대학교 의과학연구소 2004 건국의과학학술지 Vol.14 No.-

Smooth muscle contraction is regulated by intracellular Ca^(2+) ([Ca^(2+)]_(i)) and the phosphorylation of myosin light chain (MLC). However, various kinds of vasoconstrictors induce a further contraction at a given [Ca^(2+)]_(i), and elicit a sustained contraction under Ca^(2+) -depleted conditions, referred to as "Ca^(2+) -sensitization", in intact and membrane-pen-neabilized smooth muscle. Previously, several molecules, including protein kinase C (PKC), RhoA, and mitogen-activated protein kinases (MAPK), have been suggested as candidate regulators of Ca^(2+) -sensitization. In the present review, we describe the role of PKC, RhoA, and MAPK in the regulation of Ca^(2+) -sensitization, and suggest a new model in research for the regulation of smooth muscle contraction.

Ion concentrations and osmolalities of the body fluid and oxygen consumption of the larvae of the freshwater crab, under the influence of various salinities and water temperatures were studied. The level of Na^+ and Cl^- ions in the body fluid of the crab placed in the low salinities (freshwater and 30% seawater) were higher at the low temperature(16℃) than high temperature (30℃). However, the crab in the high salinity (90% seawater), those ions in the body fluid were higher at the high temperature (30℃) than the low temperature (10℃). When the zoea larvae were young (first and second stages), the ion concentrations of the body fluid were more affected by salinities and temperatures of the media. The salinity levels of the media more influenced the levels of K^+ ions of the body fluid of the larvae than the temperature. The osmolalities of the body fluid of the larvae was almost isotonic when they were place at 70% seawater (24.5‰). Oxygen consumption of individual larva was lower in zoea 1 and 2 stages than the other stage larvae. The high oxygen consumption of the larvae was observed at 70% seawater compared to the other salinity levels.
