The concept and definition of nursing and her role have been changing in accordance with the socio-cultural factors of the initial society. At present, nursing is conceptualized as a health care profession assisting man to restore, maintain and promote health by providing knowledge, wilt strength and resources through various processes of interaction. Man′s behavior, of individual and group activities for health inclusive, is driven by the initial man′s value orientation. The purpose of this study is to investigate the value orientation regarding health of rural health center milieu in order to give data for; 1. the planning for the delivery of community nursing service, 2. the health education plan at all level of nursing care activities, and 3. the planning of curriculum for nursing education. A hundred opinion leaders among the labor population residing in rural areas (P-group), hundred and six professional nurses at rural health centers (N-group) were indirectly interviewed through questionaries. And ninety five of N-group were interviewed likewise of their perceptions of P-group (NP-group) from July 15, to October 15, 1974. The result is as follows: 1. Maintenance of health is revealed to be the most valued component for man′s happiness in all the three groups. (P-group: 7.30 S. D.=1.31), (N-group :7.84 S. D. =49), and (NP-group : 5.93 S. D. =2.28) 2. The average value score of the maintenance of health revealed significant difference by P〈.001 level between each of the three groups. (Between N-group and P-group : T= -4.07 P and NP ; T=-6.93, N and NP: T=-9.35) 3. Basic health maintenance activities necessary for maintenance and promotion of personal health were moderately valued by all the three groups, P-group ; 3.74 (S. D. =.43) , N-group: 3.52 (S. D. =.34), NP-group: 3.07 (S. D. :.55) Among the 8 categories of basic health maintenance activities, "food intake" was highly valued by P-group (mean value score; 4.00 S. D=.51) , "exercise and rest" and "personal cleanliness" was highly valued by both P-group (4.02, 4.08) and N-group (4.08, 4.22). 4. The mean value score of basic health maintenance activities revealed significant difference by P〈.001 level between each of the three groups (between P-group and N-group: T=-4, 07, N-and NP: T=-6.93, P and NP T=-9.35) 5. Among the 30 questionaries, dynamic activities for health maintenance were more valued in comparison to passive activities in an tile three groups. 6. In N-group, correlation between the value of basic health maintenance activities and the personal health status personal revealed moderate significance. Correlation between the value of basic health maintenance activities and the age revealed low significance. 7. In group, correlation between the value of basic health maintenance activities and; perception of personal health status revealed non significance, between the age and sex revealed low sign affiance, and between the educational status revealed moderate significance. Recommendations are as follows ; 1. The efforts towards alteration of value orientation concerning health in general in community nursing practice de focussed be that of family Planning. 2. In order to prepare professional nurses competent in understanding individual and group, social science and behavioral science be strength ended in planning nursing curriculum. 3. Milieu of nursing experience during nursing education be Planned to begin at simple nursing problem and move towards complex, f. e. home care towards health crisis situation in order to achieve dynamic role mastery.

This study intended to understand movements of turbid water in selective with drawal reservoirs before and after summer monsoon. Mean rainfall during November-May was low, compared to that during June-October. The reservoir water was discharged through watergates when previous rainfall and inflow exceeded 50 mm and $80\;m^3s^{-1}$, respectively. Intake towers were generally used except for the period of the high runoff. Average turbidity in gown-reservoir showed a difference of 29.9 NTU between premonsoon and postmonsoon. Diameter of particles of turbid water ranged between 0.435 and $482.9\;{\mu}m$. Fine particles such as clay were much denser than the larger particle. In the whole stations, clay component was relatively higher with a proportion of that in the particle distribution. Particle composition of turbid water showed that clay consisted of 94.4-98.9% and silt made of 1.1-5.6%. Analysis on turbid water movements derived from particle distribution showed a linear increase from the deep layer toward the surface layer in lower area of a reservoir. This was closely related with the hydraulic behavior of the reservoir, and heavily affected by the discharges through selective withdrawal towers and watergates. Turbid water originated from stream sediments in the middle area then resuspended in the down-reservoir causing a movement between the surface and middle layers of the reservoir. Therefore, such phenomenon needs to be understood for reservoir water quality management.

In order to investigate the effect of floor condition on the fattening performance of cattle, sixteen finishing Hanwoo steers of weighting 570kg were fed for 16 weeks to slaughter on two types of sawdust bedding pen oriented to the south(SP) and the north(NP) then obtained following results. The floor condition of SP roofed by transparent material was dry and flat during overall experimental period, whereas, that of NP roofed by solid slate was muddy and rough even in summer and fall, and then frozen in winter period resulted in interfering with the locomotion and resting behavior of steers. Average daily dry matter intake of steers was not different between tow treatments, however, the average daily gain of steers in NP and SP was 0.64kg and 0.75kg, respectively, meaning that gained 14.3% less for the NP group(p<0.05), accordingly, feed requirement(feed/gain) and TDN/gain increased by 15.9% and 15.5%, respectively. No significant differences were found in slaughter weight, carcass weight, dressing percentage, meat yield index and meat quality traits between two treatments. In conclusion, this study revealed that poor floor condition of feeding pen could decrease weight gain and feed efficiency of cattle by increasing energy consumption for locomotion and conductive energy loss while resting on the floor surface. These results indicates that housing orientation of cattle shed and the selection of roof material are important factors in beef cattle production.

Objectives : This study is to evaluate the status of health promotion behaviors and life styles in rural areas. Methods : A self-administered questionnaire survey was carried out for 1,350(men 461 persons, women ; 889 persons) people in rural areas ages of 30 years and older in Buk-myun, Uljn-Gun and Kikye-myun, Pohang-City, Kyungsangbuk-Do from March 13 to 25 in 1999. We established health promoting scores by using data results. Collected data was analyzed through the chi-square trend test, Student's t-test, ANOVA and multiple comparison. The data was analyzed using a SPSS/win statistical package. Results The age-adjusted prevalence of individual health promoting behavior by sex was 39.4% in men and 94.0% in women in regard to non smoking 39.4% and 92.5% in non-drinking 17.2% and 13.1% in physical exercise on a regular basis 79.8% and 80.0% in a regular diet 81.6% and 75.6% in maintaining desirable body mass index 81.2% and 78.2% in sufficient physical rest 84.2% and 82.1% in sufficient mental rest 48.4% and 40.6% in supplemental intake for health. The age-adjusted proportion for a screening examination in stomach cancer by sex was 39.9% in men and 37.1% in women 31.8% and 28.0% in liver cancer 17.0% and 12.7% in colon cancer 37.0% and 31.0% in undergoing a medical health screening. The health promoting scores were statistically significant, higher in the younger aged women's group(p<0.01). In spite of very low health promoting scores, some men thought of themselves healthy. Conclusions : The health promoting scores showed a gradual improvement as ages in men increase. Although men in ages of 30 to 40 were found to have lower scores in their health promoting scores, they were still to believe that none of health status is problematic. However, it was shown a vice-versa effect in women. They thought of their health as in a bad condition, but in measurement scores outranked their personal beliefs. In general, as ages increase one tends to consider of his or her health status poor. Therefore the plans for health improvement are needed to be come up.

This study was conducted to investigate the effect of different farrowing space, narrow and wide, on the sow performances and piglet growth performances. The $1.5m^2$ of narrow farrowing space was determined as the size of farrowing crate. The $3.0m^2$ of wide space for farrowing sow was the same of farrowing pen to allow the behavior freedom of sow. Baby piglets in the wide farrowing space was protected from crushing of sow by installation of safety bar. The pregnant sows used in this study were stall-housed during gestation and moved to each farrowing spaces on 8 d before parturition. Feed intake, backfat thickness and body condition score of sow were not affected by both farrowing spaces. However, the changes in backfat thickness and body condition score between farrowing and weaning in wide farrowing space were lower (p<0.05) than in narrow farrowing space. The return to estrus of sow was remarkably decreased in wide farrowing space compared to sows in narrow farrowing space. The lower number of stillbirth and higher mortality of piglets were observed in wide farrowing space. From the results, although wide farrowing space could be practically acceptable in terms of sow performances, possible cause of mortality of piglets should be scrutinized through observation of piglet and sow behaviors.

This study examined the eating habits and preferences of foods according to the age of children with autism spectrum disorders and identified the nutritional needs of parents to support their healthy eating habits and provide basic data for the development of educational programs. A survey of 100 parents of children with autism spectrum disorders was conducted on their children's snack intake, food preferences, and parents' nutrition education needs. As a result, there were four times more boys than girls, and the body mass index differed according to age (p<0.001). Most children ate snacks more than once a day, and parents found that they wanted to develop nutritious snacks that could replace high-protein, low-calorie meals with the minimal use of additives. For the food preference, there was a significant difference in grains and starches, vegetables/seafood and fruits, milk and dairy products (p<0.05), fats and sugars, and Korean fermented pastes (p<0.01) between the two age groups. Regarding whether nutrition education was required, many parents had a high demand for nutrition education (4.24±0.70), and the intention to participate was 3.62±1.09. The most important content to be dealt with in parent education was 'Inducing a change in bad eating habits and behaviors', which was the highest (63%), and mostly face-to-face education was preferred. In conclusion, young children require diet education, and older children need to focus on weight control and obesity.

This experiment was conducted in three trials to evaluate optimal ambient temperature for a novel milk replacer feeding system designed for early-weaned pigs, compared to commercial dry diets fed within a conventional hot nursery. A total of 165 PIC genotype pigs were weaned at $13.89{\pm}0.7$ days of age and allotted to one of two dietary treatments in three trials based on weight and litter origin. Each trial consisted of pigs fed dry diets (DD) and pigs fed milk replacer (MR) which was offered in one of 3 different ambient temperatures. Pigs fed milk replacer were housed in a specialized nursery building in which one half of each pen contained an enclosed hover that was thermostatically maintained at $32^{\circ}C$ while the exterior ambient temperature (where milk was fed) was set at either 17 (trial 1), 24 (trial 2) or $32^{\circ}C$ (trial 3). Pigs fed dry diets with the conventional nursery were maintained at $30^{\circ}C$ for each trial. From d 21 to d 49, all pigs were fed DD within a standardized hot nursery environment. During the first week (d 14-21), pigs fed MR showed increased ADG from 214% to 228% over control pigs fed DD (p<0.001), regardless of ambient temperature. As ambient temperature was increased from 17 to 24 to $32^{\circ}C$, ADG of MR-fed pigs was increased by 214%, 220% and 228% over those of pigs fed DD, respectively. ADFIs of MR-fed pigs at $17^{\circ}C$, $24^{\circ}C$, and $32^{\circ}C$ compared with pigs fed DD were increased by 108%, 139% and 164% from d 14 to d 21, respectively. Fed efficiency (G/F) of MR-fed pigs at $17^{\circ}C$, $24^{\circ}C$, and $32^{\circ}C$ compared with pigs fed DD were 199%, 162% and 139% of those of pigs fed DD, respectively. As ambient temperature increased, diarrhea scores showed a slight tendency to increase. The advantage of MR feeding was greater when the ambient temperature was higher, but G/F was impaired with increased ambient temperature. We conclude that ambient temperature within the specialized nursery influenced behavior, MR feed intake, and probably piglet energy expenditure. There were no differences between MR-fed and DD-fed pigs for ADG, ADFI and G/F in the subsequent growth period (d 21 to d 49, p>0.05). Maximal advantage of MR feeding was obtained at the intermediate ($24^{\circ}C$) ambient temperature during the overall period (p<0.05). Results from this experiment indicate that a milk replacer feeding system utilized in the early postweaning period can maximize pig growth performance, and that ADG, ADFI and G/F were affected by different ambient temperatures within MR-fed pigs. The high or low temperatures could not support the maximal growth of pigs fed MR.

Certain amino acids are essential precursors of a variety of important biomolecules in addition to their major function as protein building blocks. ${\delta}$-Aminolevulinic acid (ALA) is synthesized from the condensed form of succinyl-CoA with glycine after decarboxylation catalyzed by ALA synthase. The objective of the study was to determine the effects of ALA supplementation on growth performance, behavioral characteristics and hematological/immune status in nursery pigs. A total of 144 pigs weaned at 21 d of age were allotted to three dietary treatments representing (-) control (w/o antibiotics; NC), (+) control (w/carbadox at 50 mg/kg; PC), and the treatment group with ALA supplementation (0.05%; TA). Each treatment had 6 pens (replicates) with 8 pigs per pen. Pigs were fed phase 1 (21.9% CP, 1.40% Lys) and 2 (20.6% CP, 1.15% Lys) experimental diets for 3 and 2 wks, respectively. Feed intake and weight gain were measured weekly during phase 1 and at the end of phase 2. At the end of phase 2, blood samples were taken and analyzed using an automated hematology analyzer. Skin color and activity of pigs (48 h) from all pens in each treatment were measured at the second week of phase 2. Growth performance was not affected (p>0.05) by the dietary supplementation of ALA during the 5 wk nursery period. Pigs in the TA (6.46) and PC (6.68) had a higher (p<0.05) number of red blood cells ($10^6cell/{\mu}L$) than pigs in the NC (6.15). Pigs in PC (12.16) had a higher (p<0.05) hemoglobin level (g/dL) than pigs in the NC group (11.29) and the TA group (11.47). Pigs in the TA and PC had darker (p<0.05) and less (p<0.05) yellow skin color than pigs in the NC. Pigs in the PC tended (p = 0.081) to be less active than pigs in the other groups. There were no differences in behavioral characteristics between the NC and the TA. The data suggest that ALA supplementation has no adverse effects on growth performance of nursery pigs. Moreover, ALA supplementation increased red blood cell counts which may be beneficial to pigs.

Objective : To elucidate the correlates of self-rated fatigue in Korean employees. Methods : The data for 10,176 (men, 7,984; women, 2,192; mean age, 34.2; SD: 8.8) employees recruited from a nationwide sample were examined. A structured questionnaire was used to measure the participants' fatigue, sociodemographics (sex, age, education, and marital status), job-related characteristics (work duration, grade at work, work hours, shiftwork, employment type, and magnitude of workplace), and health-related habits (smoking, drinking, coffee intake, and exercise). Two types of measurement for fatigue were used to evaluate the magnitude of fatigue: self-rated question and a standardized measurement tool (Multidimensional Fatigue Scale: MFS). Results : According to the self-rated fatigue, 32% of employees reported that they felt fatigue for the past two weeks, and 9.6% of males and 8.7% of females had experienced excessive fatigue (6 months or more). Hierarchical multiple regression analysis showed that fatigue measured by MFS was more common in women, younger, college or more graduated, single, and employees who do not regularly exercise. Fatigue was also associated with long work hours, and the size of the workplace (<1,000 employees). Conclusions : These results suggest that fatigue has been considered as a common complaint, and that it is affected by job-related factors like work hours and the workplace size as well as sociodemographics or health-related behaviors. Further research is needed to clarify the effects of fatigue on adverse health outcomes, work performance, work disability, sick absence and medical utilization, and to examine the relationship of job characteristics (e.g.: work demand, decision latitude) to fatigue.

This study was performed to investigate the memory enhancing effect of Poria cocos Wolf (Hoelen cum radix) against scopolamine-induced amnesia in Sprague-Dawley (SD) rats. To induce amnesia, scopolamine (0.75 mg/kg) was intraperitonically injected into SD rats 30 min before starting behavior tests. We have conducted Morris water-maze and Y-maze tests to monitor learning and memory functions. Poria cocos effectively reversed scopolamine-induced memory impairment in SD rats which was represented by an improvement of mean escape latency in water-maze test and spontaneous alterations in Y-maze test. To elucidate possible molecule mechanism, we have measured mRNA as well as protein expression of acetylcholine esterase (AchE), choline acetyltransferase (ChAT), muscarinic acetylcholine receptor (mAchR), and brain-derived neurotrophic factor (BDNF) using RT-PCR and Western blot analysis, respectively. Poria cocos increased mRNA levels of ChAT and mAchR in rat hippocampus compared with those in the scopolamine-injected amnesic group. In addition, protein expression of ChAT and BDNF was also elevated by Poria cocos intake. Furthermore, as an upstrem regulator, the activation of cAMP response element-binding protein (CREB) was assessed by immunohistochemistry. In this immunohistochemical analysis, the phosphorylation of CREB (p-CREB) was reduced by scopolamine injection, which was restored back to control levels by administration of Poria cocos. These results suggest that Poria cocos may improve memory and cognitive deficit in amnesia and have therapeutic potentials through up-regulation of ChAT, mAchR, and BDNF, which seemed to be mediated by activation of CREB.
