This work was conducted to study the improvement of reproduction rate from the breeding data collected from four farms from January 2007 to October 2010. The average numbers of service per conception were 1) A farm $1.7{\pm}0.1$ times, 2) B farm $1.5{\pm}0.1$ times, 3) C farm $1.5{\pm}0.1$ times, 4) D farm $1.4{\pm}0.1$ times. The average days from calving to conception was $77.4{\pm}4.8$ days in A farm, $150.8{\pm}11.2$ days in B farm, $90.4{\pm}4.5$ days in C farm, and $71.4{\pm}2.5$ days in D farm. Number of artificial insemination (AI) service per conception was higher at the 30 days before first AI ($2.1{\pm}0.2$ times) than at the 31 days after first AI, and the days from calving to conception were shorter at the 90 days before first AI than at the 91 days after first AI. After timed AI (TAI) treatment, the pregnancy rate was 60.3% for the 58 cows with reproductive disorder. In order to improvement of reproduction rates, the farms has to improve the accuracy of estrus detection, pregnancy diagnosis, check-up for reproductive health, and control of day for first AI periods after calving. The result suggests that farmers need the careful management and reproductive examination of farm animals to improve of reproductive efficiency.

We surveyed Korean pregnant women who participated in the Maeil mothers' club and factory tour from March to April, 2004 and assessed volunteers' hemoglobin (Hb) levels. The average Hb level of 747 subjects was $11.5{\pm}1.5g/dl$ and anemic subjects were 268 women, 35.9% of total subjects. The ratio of anemic subjects was 42.9% in the first trimester, 43.6% in the second trimester and 29.1 % in the third trimester. About 87.9% of subjects began to take health foods after conception. Seventy nine percent of subjects took iron supplement as one of health foods and 73.8% of them began it in the second trimester. The results of this study showed that health foods were more effective than iron supplement alone in improving the iron status of Korean pregnant women. Therefore, the better improvement effects are expected when pregnant women begin health food-based approaches as early as possible before pregnancy to improve pre-pregnancy iron reserve.

Obesity is psychological and socioeconomic problems as well as health problems related to physical disease and disorder. The obesity epidemic, including a marked increase in the prevalence of obesity among pregnant women, represents a critical public health problem throughout the world. Gung-Gui-Tang (GGT), a prescription of traditional Korean medicine, has been used to treat dizziness due to loss of blood as well as static blood after childbirth. However, the therapeutic potential of GGT on postpartum obesity has not been fully elucidated in an experimental model. In our research, GGT inhibited the increases of body weight and adipose tissues in postpartum mice fed a high-fat diet. GGT also inhibited the elevations of plasma lipid profiles such as triglyceride, low-density lipoprotein cholesterol, total cholesterol, and glutamate pyruvate transaminase. Overall, these results provide evidence that GGT can help to inhibit postpartum obesity and open new perspective to recover the shape of mother into the moment of conception.

The growth and health of the fetus and neonate are directly influenced by the nutritional and physiological status of sows. Sows are often under catabolic conditions due to restrict feeding program during pregnancy and low voluntary feed intake during lactation. The current restrict feeding program, which aims at controlling energy intake during gestation, results in an inadequate supply of dietary protein for fetal and mammary gland growth. Low voluntary feed intake during lactation also causes massive maternal tissue mobilization. Provision of amino acids and fatty acids with specific functions may enhance the performance of pregnant and lactating sows by modulating key metabolic pathways. These nutrients include arginine, branched-chain amino acids, glutamine, tryptophan, proline, conjugated linoleic acids, docosahexaenoic acid, and eicosapentaenoic acid, which can enhance conception rates, embryogenesis, blood flow, antioxidant activity, appetite, translation initiation for protein synthesis, immune cell proliferation, and intestinal development. The outcome is to improve sow reproductive performance as well as fetal and neonatal growth and health. Dietary supplementation with functional amino acids and fatty acids holds great promise in optimizing nutrition, health, and production performance of sows and piglets.

The purpose of this study was to identify the major factors affecting performance in health promoting behavior. The subjects for this study were 414 workers employed in one transportation manufacturing plant in Pusan and were obtained by a convenience sample. Data were collected from November 11th to December 21th, 1996 by structured questionnaires. Collected data were analyzed by SPSS PC. The results of this study are as follows. 1. The average score of performance in the health promoting behavior was 2.42 ; the range of the score was from 1.44 to 3.71. The variable with the highest degree of performance was self-actualization, whereas the one with the lowest degree was exercise. 2. In the relationships between demographic variables and performance in the health promoting behavior, only the shift system showed statistically significant differences in the total of health promoting behavior ; especially the group of no shift operation was higher in the performance of subscale such as exercise, nutrition, interpersonal support than that of the shift operation. Some demographic variables showed significant differences in the subscale of the health promoting behavior ; age, worker's career and marital status. 3. Performance in the health promoting behavior was significantly correlated with perceived health status, health conception, self-efficacy, perceived benefits and perceived barriers. 4. The most important factor that affects performance in the health promoting behavior was self-efficacy. The combination of self-efficacy, perceived benefits, perceived health status, perceived barriers, shift system and department of work accounted for 31.05% of the variance in health promoting behavior.

This research have aimed for analyzing the effect of relative factors on healthy life styles by the income level in a medium-sized city. Especially, the research tried to figure out whether the public health center's health-promotion-activity had different effects on healthy life styles by the income level. The random sampled data of 809 citizens aged between 19 and 69 were analyzed through phone survey by the Korea Gallop inc(surveyed from 2006.10.11 to 10.13). In the low socioeconomic status, the relation between people's positive conception about public health center's health-promoting-program and healthy behavior tendency is low. But in the high socioeconomic status, the relation is high. This result suggest that the effect of public health center's health promotion programs on healthy life styles is different by income level.

This study was aimed at comparing and evaluating one main role, the professional self concept and job satisfaction of public health nurses and clinical nurses. Method: The data was collected from 72 nurses in 8 health centers and 86 nurses in 5 hospitals in Daegu city and Kyungpook province from May 5th to June 5th, 2001. This study was interviewed by trained social workers. The origin of questionnaires used in this study were PSCNI(Professional Self-Concept of Nurses Instrument) to measure the professional self concept of nurses and JDI(Job Descriptive Index) to measure the job satisfaction of nurses. The data was analyzed by SAS(version 6.12) and statistical methods used were Chi-square test, t-test, ANOVA(analysis of variables) and ANCOVA(analysis of covariate). Result: The findings of this study were as follows: 1. The most important domain in the main role of public health nurses were as counsellors, managers, mediators and evaluators. In clinical nurses, their main roles were, directors of nursing, researchers, spokesmans, and informers. 2. Public health nurses showed lower scores in the professional self concept of nurses than clinical nurses, what statistically significant tool was used to suggest this finding. 3. Public health nurses showed higher scores in job satisfaction than clinical nurses, but again, explain the tool used in these findings for give a rationals. 4. For public health nurses, general characteristics which affected professional self concept were age, educational level, and duration of job. In clinical nurses, the general characteristics which affected professional self concept were age, religion, marital status, and duration of job. 5. For public health nurses, there was no general characteristic which affected job satisfaction. In clinical nurses, the general characteristics which affected job satisfaction were age, religion, and duration of job. Conclusion: Nursing profession should give a training to competent nurses who can deliver high quality care to meet the needs of health consumers. The role of nurses has been expended and specialized as health conception has been changed in Korea.

The organized community is the one of the best system for the effective public health administration, and a model area was selected for the study to see what would be achieved when a certain small community is placed under the special public health control based on the family unit. The 178 families involved total of 875 populations. The rate of vaccination with B.C.G. among 191 infants and children could be increased upto 100.0% from 72.5% of the time when the basic study was performed after 8 months period of this study; 99.0% from 47.1% with D.P.T.; 96,9% from 71.7% against smallpox; 83.2% from 69.1% against poliomyelitis; but only 25,7% from 21.5% against measles. The status of family planing was 36.8% among 155 women of possible conception at the time of the basic research. And, at the end of this study, the number of women utilizing one of the methods of contraception for family planning were increased upto 52.9% among the same number. The most frequently utilized method was 34.1% of oral pills followed by 30.5% of intrauterine device; but both of which had higher rate of interruption of use because of the complications, 14.3% and 16.0% respectively. The 10 pregnant women at the time of basic research experienced normal deliveries during the period of study and they had received pre and postnatal health care through this health center. The status of oral hygiene, pulmonary tuberculosis control, and parasitological examination were also reported as well as the cases with diseases seen among the population and vaccinations performed against other infectious diseases. The stress on discussion was placed upon the effectiveness of public health administration when it is undergone on the individual family unit to achieve the best results. However, the shortness of both personnel and material resources were considered to be the one of the major difficulties retarding the generalization of the idea obtained through this study based on family unit public health administration.

1) Table salt (=NaCl=common salt=salt) is scientifically characterized, and the significant role in dietary and daily life has generally been discussed from the standpoint of human ecology. 2) In dietary life, salt fundamentally gives a deliciousness to dishes and nutro-physiologically functions to keep homeostasis in the body. Meanwhile, the excessive intake of salt often causes the high blood pressure and induces several fatal diseases. 3) In daily life, salt derivatives(Na-, Cl-compound) are quite useful widely over food, clothing and housing. Meanwhile, some of them especially organochlorine compounds often pollute the environment and damage the humans and or ecology as so-called environmental hormone resulting in dioxins. 4) For the ambivalence of salt in health and environment, humans, but not salt, are wholly responsible. The fact would go not only to salt but also generally to resources on the earth. 5) Humans should adequately be moderate in utilizations and consumptions of salt and or resources. Everything must be kept with in bounds. This conception would surely bring the stable maintenance and the sound development to the system of human ecology as well as global ecology.
