A growth trial and a digestibility trial were conducted to examine the effect of feed particle size on the performance, nutrient digestibility, gastric ulceration and intestinal morphology in pigs fed barley-based diets. Barley was processed through a hammer mill to achieve four diets varying in particle size (average particle $size{\pm}standard $deviation): coarse ($1,100{\pm}2.19\;{\mu}m$), medium ($785{\pm}2.23\;{\mu}m$), fine ($434{\pm}1.70\;{\mu}m$) and mixed (1/3 of coarse, medium and fine) ($789{\pm}2.45\;{\mu}m$). Sixty-four entire male pigs were used in the growth trial and the diets were fed ad libitum between 31 kg and 87 kg live weight. Following slaughter, stomach and ileal tissues were scored for integrity (ulceration or damage) and histological measurements taken. Twenty-four entire male pigs were used in the digestibility trial, which involved total faecal collection. Over the entire growth phase, there were no differences (p>0.05) in average daily gain and feed conversion ratio between pigs fed diets of different particle size. Pigs fed the coarse and medium diets had lower (p<0.05) stomach ulceration scores (0.20 and 0.25, respectively, on a scale from 0 to 3) than those fed the mixed (0.69) or the fine diets (1.87). The stomachs of all animals fed the fine diet had lesions and stomach ulcerations were present only in this group. Pigs fed the fine diet had thicker (p<0.001) ileal epithelial cell layer with no differences (p>0.05) being observed for villous height or crypt depth. Faecal digestibility coefficients of neutral and acid detergent fibre were the highest (p<0.05) for the mixed diet, intermediate for the fine and coarse diets and the lowest for the medium diet. A similar numerical trend (p = 0.103) was observed for the apparent faecal energy digestibility coefficient. It is concluded that, with barley based diets, a variation in average particle size between $400{\mu}m$ and $1,100{\mu}m$ had no effect on pig performance but the fine dietary particle size affected the integrity of the stomach, as well as the structure of the small intestine, thus compromising overall gut health. Our data also demonstrate that changes in particle size distribution during the digestion process, rather than average particle size or particle size variation, are related to apparent faecal digestibility.

We study convergent influence on depression and its association with self-esteem, fatigue and psychosocial stress among General Hospital Administrative Staff(GHAS). The subjects were 201 randomly extracted GHAS from 9 general hospitals in J City, Data collection was carried out via a structured self-administered questionaries from Jul. 3rd, 2017 to Jul. 29th, 2017. Depression was positively correlated with three sub-domains of fatigue and psychosocial stress, and it was negatively correlated with self-esteem. With the analysis of covariance structure, depression was more influential on self-esteem than fatigue and psychosocial stress. The study found the higher fatigue and psychosocial stress, and the lower self-esteem tend to increase depression. The results indicate that the efforts, to increase self-esteem, and to decrease fatigue and psychosocial stress, are required to decrease the depression of GHAS. The results are expected to be useful for industrial health education and job management to decrease the depression of GHAS. In the following study, the analysis about convergent additional factors of influence on the depression of GHAS will be needed.

The purpose of this study is to investigate the stress and coping level as a result of dysmenorrhea which was experienced by girls. For the collection of data, the girls from the 1st to the 3rd grade in middle school in Seoul were selected through a random sampling technique. The survey was conducted from the 1st. to the 14th of June, 1991 by the use of questionnaires made after a pilot study. The final subjects for analysis were restricted to only those who had experienced me~arche, the number of which totaled 1,131. The stress, coping level, and other variables, were tested and analysed by descriptive statistics (eg, frequency, percentage, mean and standard deviation), t-test, ANOVA and Pearson's correlation coefficients. The obtained results are summarized as follows. 1. The chronological start for menarche was at a mean age of 13.1 The respondents who had experienced menarche numbered $70.9\%$ of the 1st grades and $96.2\%$ of the 2nd grades in middle school, otherwise the starting age for menarche was in the 4th grade in primary school. 2. Their menstrual cycle and period were longer than adult's one. The number of students studied who had experienced dysmenorrhea during their menstrual cycle were 860, and 650 of those revealed that their mothers or sisters had experienced similar problems. 3. The subjects who were late or head left early rather than being absent from school every menstruation cycle were more stressful. The results are thought to show that the girl's perception of dysmenorrhea seems to be more sensitive than adult's one. 4, A significant negative correlation was found between the perception of menstrual flow and strees level. It means that an increase in the stress of dysmenorrhea was associated with decreased menstrual bleeding. The degree of hypochondrical concern assessed by the girls was significantly correlated to stress and coping level. When the girls perceived high stress as a result of dysmenorrhea, they worried about their physical health more. The above results lead us to the suggestion that the starting point of early education with a school program is appropriate for the 4th grade in primary school. Especially if the girls in middle school should be required to give the information about correct knowledge and sufficient self -care management of menstruation monthly, if this could be implemented the loss in school days among the students due to dysmenorrhea would be minimized with more ease.

This study was intended to assess the need of home nursing care and analyze the effect of home nursing care, and find out the problems during the performance of home nursing care for the chronic patients among the low-income people in urban area. Data collection by interview was carried out from Nov. 1991 to Jul. 1992. The main results were as follows; 1) Total subjects for the need assessment of home nursing care were 123 households wi th 488 persons in a urban poor area. Over half of households $(57.7\%)$ was teenage family. The overall living conditions were poor and the average monthly income was 580 thousands won. $74.8\%$ of subjects was covered by medical care insurance and only $4.7\%$ was covered by public assistance. The morbidity rate was $8.2\%$ among 488 subjects and $27.5\%$ of them was not treated at all, $30\%$ was treated in utilizing pharmacies or local clinics. 2) The subjects of home nursing care were 46 with Hypertension or DM who agreeded the participation of study among registered patients at a public health center in Incheon. Home visiting was performed at intervals per one month for one year. Most of them were the elder(mean age=61 years) and long term patients(7.8 years continued). Home nursing care was effective. That is, blood pressure(including systolic and diastolic pressure) was significantly reduced (t(n=22)=2.31, P=.031, t(n=24)=4.16, P=.000 respectively) and knowledge of disease(t(N=46)=-7.63, P=.000), attitude of disease (t(N =46) = -4.92, P=.000), and self-care(t(N =46) = -4.89, P= .000) were significantly improved through home nursing care. But there was no difference in blood sugar for diabetics between the beginning and the end of visits. At the beginning of visit for home nursing care, sex$(\beta=-0414,\;t=-3.012)$ and nursing need({3=.310, t=2.164) were influencing self-care, and duration of disease$(\beta=.297,\;t=2.106)$ and nursing need $(\beta=.385, t=20417)$ were influencing blood pressure, blood sugar level. Namely, the subjects who were male and had higher nursing need showed better self-care and the longer duration of disease and the higher nursing need were relationship with the better blood pressure and blood sugar level. At the end of visit for home nursing care after one year, the blood pressure and blood sugar level was influenced by age $(\beta.320,\;t= 2.242)$, duration of disease ($(\beta.352,\;t= 2.395)$ and nursing need $(\beta=.350,\;t=2.623)$ and self-care had no influencing factor. The higher age and the longer duration of disease and the higher nursing need were relationship with the better blood pressure and blood sugar level. 3) The problems that were found out during the performance of home nursing care were the absent of useful protocols for services and the clear evaluation base, and the difficulty of teaching elders who were the major part of our subjects.

This descriptive study was done to investigate the proportion of mothers breast feeding and identify factors which influence breast feeding. The subjects were 320 mother who child under five years of age, living in WonJu and their children who numbered 530. Data collection was conducted at various places in the WonJu area using survey questionnaire. The results were as follows : 1. The proportion of children receiving breast feeding was 23.3%, mixed feeding 31.7%, milk feeding 45.1%. The most frequent duration for breast feeding was one month, the mean duration was six months. 2. The major reasons for breast feeding were for the health of the child 52.5%, for emotional attachment with the child 34.2%, and as the expected way of feeding 29.5%. 3. The major reasons for interrupting breast feeding were jobs 26.1%, illness of the child or mother 16.1% abnormality of the breast of nipple 12.7% others 31%. 4. The major reasons for quitting breast feeding were insufficient breast milk 34.5%, job 19.6%, diarrhea in the child 9.9%. 5. The factors influencing breast feeding were educational status and the presence of a job. 6. The husband's attitude to breast feeding was very positive 82.3% and the subjects were supported by their mothers and husbands. But the major information sources about breast feeding were the mass media 30.4% and relatives 22.0%. 7. The breast feeding mother reported experiencing positive and satisfactory feelings, but the milk feeding mother reported experiencing negative and guilt feelings. Also the breast feeding mothers perceived their children as very healthy with a stable emotional status. The results showed the breast feeding ratio in WonJu to be very low and problematic and the subject mothers strongly need information about breast feeding and support while breast feeding. Therefore it is recommended that an education program for community women and other people, like husbands, and grandmothers, be developed along with an education program for university students and other young people to provide them with preparatory information as they begin to think about marriage and families.

Recently attention has been focused on the effects of early intervention, or its lack, on both normal and preterm infants. Particularly numerous studies suggest that premature infants are not necessarily understimulated but instead are subjected to inappropriate stimulation. Developmental support and sensory stimulation have become clinical opportunities in which nursing practice can impact on the neurobehavioral outcome of premature infants. Developmental care has been widely accepted and implemented in neonatal intensive care units across the country. Increasingly, attention and concern in caring for low-birth-weight infants and premature infants has led clinicians in the field to explore the effects of a complex of interventions designed to create and maintain a developmentally supportive environment; to provide age-appropriate sensory input; and to protect the infant from inappropriate, excessive and stressful stimulation. The components of developmental care include modifications of the macro-environment to reduce NICU light and sound levels, care clustering, nonnutritive sucking, and containment strategies, such as flexed positioning or swaddling. Sensory stimulation of the premature infants is presented to standardize the modification of a developmental intervention based on physiologic and behavioral cues. The most appropriate type of stimuli are those that are sensitive to infant cues. Evaluation of infant physiological and behavioral responds to specific intervention stimuli may help to identify more appropriate interventions based on infants' cues. A critical question confronting the clinician is that of determining when the evidence supporting a change in practice is sufficient to justify making that change. There are acknowledged limitations in the current studies. Many of the studies examined had small sample sizes; used nonprobability sampling; and used a phase lag design, which introduces the possibility of threats to internal validity and limits the generalizability of the results. Although many issues regarding the effects of developmental interventions remain unresolved, the available research base documents significant benefits of developmental care for LBW infants in consistent outcomes, without significant adverse effects. Particularly, although the individual studies vary somewhat in the definition of specific outcomes measured, instrumentation used, time and method of data collection, and preparaion of the care providers, in all studies, infants receiving the full protocol of individualized developmentally supportive care had improvements in some aspect of four areas of infant functioning: level of respiratory or oxygen support, the establishment of oral feeding; length of hospital stay, and infant behavioral regulation. In summary, based on the available literature, individualized developmental intervention should be incorporated into standard practice in neonatal intensive care. And this implementation needs to be coupled with ongoing research to evaluate the impact of an individualized developmental care programs on the short- and long-tenn health outcomes of LBW infants.

This study was conducted to investigate the relationship between sleep quality and depression level of male workers in the manufacturing industry. The survey subjects were 856 male workers in the manufacturing industries in D city. Data collection was conducted through a self-administrated questionnaire survey during the period from March 1 to April 30, 2019. The distribution of depressive level among subjects differed significantly according to various variables of sociodemographic characteristics, health related behaviors and job related characteristics. In addition, the distribution of the depressive group was significantly higher in the group with worse quality of sleep (PSQI). Depression level showed a significant positive correlation with sleep quality. The risk ratio of the depressed group was significantly higher than that of the sleep quality. The results of this study suggest that the depressive level of male workers in the manufacturing industry is significantly related to the quality of sleep as well as sociodemographic, health related and job related characteristics. Therefore, it is necessary to make efforts to improve sleep quality to reduce the level of depression of workers.

It is necessary to investigate the relationship between ego-resiliency, organizational loyalty, organizational commitment, and emotional intelligence of hospital administrative staff and the effect of these factors on emotional intelligence. Therefore, this study investigated the relationship between these factors and emotional intelligence and identified the convergence effect on emotional intelligence in hospital administrative staff. The subjects of the survey were randomly selected 212 administration staffs at 19 hospitals selected from the J area. The data collection was conducted for about a month from May 1 to 31, 2019. The form of the questionnaire used structured anonymous self-administered responses. Emotional intelligence showed a positive correlation between ego-resiliency, organizational loyalty, and organizational commitment. According to the analysis, efforts to enhance ego-resiliency, organizational loyalty, and organizational commitment are needed to increase the emotional intelligence of hospital administration staffs. The findings may be used as basic materials for hospital job management and industrial health education that will raise the emotional intelligence of hospital administration staffs. Future research needs to investigate additional factors related to emotional intelligence and various emotional factors of hospital administrative staff.
