In human body, catecholamines, such as epinephrine and norepinephrine, can be increased anxiety, blood pressure and pain etc. The inhibitory effects of TENS, electroacupuncture and massage on the release of epinephrine, norepinephrine from sympathetic nerve endings has already been known. However, the effects of silver spike point stimulation on the catecholamines was not well understood. Therefore, the purpose of this study was to characterize the SSP-induced inhibitory effects of catecholamines. The following results were obtained. (1) The studies on urinary catecholamines released that the levels of epinephrine and norepinephrine of continue type SSP stimulation group were significantly lower than those in the control group in human in vivo. (2) The dose-response curves of epinephrine and norepinephrine in rat aortic smooth muscle strips were increased dose dependent manner respectively. However, the contractile response of norepinephrine in rat aortic smooth muscle strips were slightly differentiated. It is concluded that the SSP stimulation reflects to the inhibitory effects of epinephrine and norepinephrine in men. Especially, we believe that the amplitude-frequency modulation, such as continue type a)1d frequency modulation type, of SSP stimulation plays a role in regulating catecholamines.

Background : The purpose of this study is to provide the basic data according to cognitive function, that will help activities of daily living of the elderly through the comparative study of activities daily living and functional training. Methods : The subjects of this study 122 patients 65 years old or more ADL and cognitive function assessment was evaluated. They were registered in the Elderly in nursing homes and welfare centers, located in Gyeonggi. All study participants had a sufficient explanation for the purposes of research and evaluation methods and procedures for the elderly. The survey period 17 October to 11 November 2011 was conducted through face-to-face survey was conducted. Results : Cognitive function according to the K-MMSE score of 24 points or more, 23 to 18 points, 17 points or less were classified. Ability to perform activities of daily living (personal hygiene, bathing, toilet use, stair climbing, dressing, stool control, urinary control, gait, chair/bed, etc.) according to the degree of cognitive function by evaluating the ability to perform daily living compared results in all variables were statistically significant (p<.5). Conclusion : As a result, the higher cognitive functions can be seen that the higher the ability to perform activities of daily living.

1. 기초간호교육제도- 기초간호교육은 4년제 대학과정과 3년제 전문 대학과정의 두 제도가 있다. 수업년한, 졸업기준 학점이 다르다. ''학술의 심오한 이론, 그 정치하고 광범한 응용방법을 교수 연구하고 지도적 인격을 도야함''은 대학의 교육목적이며, 전문대학은 ''전문적 지식과 이론을 교수''연구하며 재능을 연마하여 중견 직업인을 양성함''으로 명시되었다. 전자는 학문과 지도력에 중점을 두었고 후자는 전문적 지식과 이론에 바탕을 둔 재능의 연마와 중견직업인에 역점을 두고 있다. 교육과정의 편성비율에 있어서도 대학과정과 전문대학 과정에 현저한 차가 있다. 전문대학은 총 이수학점 중 20$\%$를, 대학과정은 30$\%$를 교양과목으로 과하고 있고, 전문대학은 전공선택과 필수를 총 학점의 80$\%$로 하는데 비해 대학과정은 총 이수학점의 50$\%$ 내외로 하고 자유선택, 부전공 등에 나머지를 할애하고 있다(표 7, 표 8) 2. 계속교육제도- 계속교육제도는 정규교육제도에 포함되고 있는 대학원 과정과 보사부장관이 인정하는 특정 기관에서 개설하는 특수분야별 수습과정들로 나눌 수 있다. 대학원 과정은 간호학 전공 외에도 보건학 교육학동 인접학문 영역을 연구하여 학위를 받고 있고 서울대학교와 연세대학교에서 박사학위 과정을 개설하고 있다. 전공분야별 간호원의 자격인정은 보건간호, 마취간호, 정신간호 분야에 가능하나 극소수의 간호원 자격을 취득하고 있다.

To evaluate the nutritional status of the children in socioeconomically high apartment com-pound a nutritional survey of 276 children in the YunJung elementary school was undertaken in July of 1990. Yunjung elementary school is situated in Youido-dong Youngdeungpo-ku of Seoul and offers school lunch program The results were as follows : Anthropometric data of subjects showed higher results than the Korean standards : 11.0% of subjects were proven to be overweight and 21.6% belonged to obese group. Mean urinary the RDA's except for intake of was 10.2$\pm$3.7 Total daily energy and nutrient intake exceeded the RDA's except for intake of iron. Carbohydrate provided 57% of total energy intake; protein accounted to for 17 ; fat provided 27% The between meals provided 27.4% of total energy intake. The survey clarified that school lunch largely contributed to the nutritional balance of these children. Family environment and anthropometric data were positively correlated with nutrient intake. The survey emphasizes the urgent need to improve the nutrition education of these children.

일반계 12품종 및 다수계 9품종에 대한 수화속도를 비교하였다. 실온에서의 쌀의 수분흡수 속도 또는 물의 확산 계수는 품종마다 독특한 값을 보였다. 쌀은 수분 흡수 속도에 따라 세 그룹으로 나눌 수 있었다. 일반적으로 식미가 좋은 품종으로 알려진 쌀은 수분 흡수 속도가 낮았으며, 대부분의 다수계 품종은 중간 정도의 수분 흡수 속도를 보였다.

The change of chlorophyll fluorescence parameters, O-J-I-P transients and psbA gene expression were investigated in the leaves of Crinum asiaticum var. japonicum on the natural condition in winter, in order to elucidate physiological responses of photosystem II (PS II) activity to winter stresses. The photochemical efficiencies of PS II, Fv/Fm, were significantly low in winter, contrary to its high value in summer. The values of I -qN and I-qP were lower in midday than at dawn or night both in summer and winter, although their decrease in midday was less in winter than in summer. In the O-J-I-P transients, the fluorescence intensity of J, I, P-step decreased remarkably depending on temperature drop in winter. And the D I reaction center protein of PS II decreased in late winter more than in early winter, concomitantly with relatively high content of description products of psbA gene in midday. These results indicate that low temperature in winter causes irreversible damage to PS II and subsequently leads to cell death.

A taxonomy which can be used conveniently for analyzing the vertical articulation of mathematics and science textbooks has been developed. It includes two types sanalysis criterion: one is based on the detail of description and the other is based on the depth of contents in terms of their sequence. These two criterion elements are combined to form groups of 'overlap', 'development' and 'gap' to represent the extent of articulation. Examples of applying the taxonomy are illustrated for the concepts of gemetrical area in mathematics and potential energy in science.

ZST powders were synthesized by coprecipitation of (Zr4+, Ti4+)-hydroxide in the presence of SnO2 particles. Zn(NO3)2 was used as a sintering additive, and according to the adding sequence, sintering and dielectric properties were investigated. Sintered densities of ZST prepared by adding Zn(NO3)2 before calcination were a little higher than those added after calcination, and dielectric properties of the specimen added by Zn(NO3)2 after calcination were better (sintered at 125$0^{\circ}C$/2 h ; Q$\times$f(GHz)=49, 000, $\varepsilon$r=41) than before calcination (Q$\times$f(GHz)=42, 000, $\varepsilon$r=39.5). Through the observation of TEM, it was identified that the cause was due to the difference of the degree of Zn2+ diffusion into grains. With increasing sintering time from 2 to 8 hrs, grain size was doubled and dielectric properties were somewhat deteriorated.

In order to understand the electrostrictive behavior of Pb(Mg1/3Nb2/3)O3-PbTiO3 (PMN-PT) solid solutions the dielectric constants the electric-field-induced strains and the pyroelectric coefficients of (1-x)PMN-xPT (x=0.1-0.4) were investigated in the temperature range -50~20$0^{\circ}C$. For x=0.1~0.35 where the phase transi-tion is diffusive the strain has a maxima at the temperature of maximum pyroelectric coefficient (depolrizing temperature) rather than the temperature of maximum dielectric constant. For x=0.4 where the phase transition is relatively sharp the strain decreases monotonically as the temperature increases. Relationships among the above experimental results are discussed.
