The purposes of this study were 1) to identify patterns and trends of studies of anxiety and stress and 2) to provide direction on which to base further research. Research studies of anxiety and stress were selected from journals of medical and nursing schools, the Korean Nurse, the Korean Nurses' Academic Society Journal, the Central Journal of Medicine, the New Medical Journal, Monthly Nurse, and from theses and dissertations, which had been conducted for the 20 years from 1970 to 1990. The total population of the studies numbered 463. Seven studies were excluded from the analysis because of duplication, so that 252 studies of anxiety and 204 of stress were analyzed. These studies were analyzed for 1) time of publication or presentation, 2) research design, 3) characteristics of subjects used in each study, 4) types of correlated variables, and 5) types of nursing interventions. Findings obtained in the study were as follows : 1. The number of studies related to anxiety and stress has increased rapidly since the early 1980's. 2. The studies were primarily descriptive throughout the 20 years. However, correlational studies, comparative studies and experimental studies slowly increased. 3. Anxiety studies tend to be conducted more on patients and stress studies with normal subjects in non - experimental research. However, experimental studies were conducted more with patients than with normal subjects. 4. In correlational studies, the trend was to study physical conditions in relation to anxiety, and coping and adaptation in relation to stress. 5. In experimental studies, teaching and information therapy and relaxation were the most popular interventions for anxiety, and supportive care for stress. On the bases of these findings, the following recommendations were made : 1. These patterns of studies related to anxiety and stress in Korea need to be compared with studies conducted in other countries. 2. More attention is needed in terms of research design, reliability and validity of tools, and results of statistical analysis. 3. Meta -analysis should be done to analyze and integrate the results of various studies. 4. For theory testing and identification of useful intervention methods, experimintal studies with the same protocols must be conducted rather than more descriptive studies.

Purpose: This research was designed as a pre-post experimental study with a nonequivalent control group to verify the effects of meridian exercise on health status, depression and self-esteem in institutionalized elderly people. Method: The research population included 38 participants, 65 years and over, who were assigned to an experimental group (18) or a control group (20). All of the participants were institutionalized in Seoul Data collection was done from October. 2000 to May, 2001 and the experimental treatment for this study, meridian exercise, was done for a total 30 minutes per session for 12 sessions over two weeks. The exercise was developed by a professor of Oriental Medicine and the researchers involved in this study. The data were analyzed using the SPSS PC+ program. Result: There were no significant differences for general characteristics between the two groups. Physical health status, mental-mood health status, depression and self-esteem were low. Differences in the physical health status of the elderly people was higher in the experimental group (t=16.299, p=.000). The effects of the meridian exercise on mental-mood health status, depression, and self-esteem were statistically significant (t= 10.301, p= .000 ; t=15.579, p=.000, t=14.571, p=.000). Conclusion: According to the results, meridian exercise should be used to improve health status, reduce depression and increase self-esteem, and so promote the quality of life for elderly People who must be institutionalized. A study to measure the physiological index in meridian exercise for elderly people is suggested as a method to set up a Korean nursing intervention to enable elderly people to manage their own health.

Purpose: This study aimed to estimate the effects of a health mentoring program on fasting blood sugar, total cholesterol, triglyceride, physical activity, self care behavior and social support changes among community-dwelling vulnerable elderly individuals with diabetes. Methods: A non-equivalent control group pre-post-test design was used. Participants were 70 community-dwelling vulnerable elderly individuals with diabetes. They were assigned to the experimental (n=30) or comparative (n=30) or control group (n=28). The experimental group participated in the health mentoring program, while the comparative group participated in health education program, the control group did not participate in any program. Data analyses involved a chi-square test, Fisher's exact test, a generalized linear model, and the Bonferroni correction, using SPSS 23.0. Results: Compared to the control group, the experimental and comparative groups showed a significant decrease in fasting blood sugar, total cholesterol, and triglyceride. Compared to the comparative and control groups, the experimental group showed significant improvement in self care behavior. However, there were no statistical differences in physical activity or social support among the three groups. Conclusion: These findings indicate that the health mentoring program is an effective intervention for community-dwelling vulnerable elderly individuals with diabetes. This program can be used as an efficient strategy for diabetes self-management within this population.

Purpose: The purpose of this study was to evaluate the efficacy of applying a defecation encouragement program for patients undergoing total knee replacement arthroplasty (TKRA). Methods: This program was based on the nursing best practice guideline: prevention of constipation in the older adult population by the National Guideline Clearing House (NGC) in 2011, which included fluid intake, bowel training, and abdominal and pelvic floor exercises. A team of one orthopaedic clinical nurse specialist and six orthopaedic nurses with a 10 years of clinical experience applied and assisted patients with the program. Formal counsel was provided by one orthopaedic doctor, one gastroenterologist, and one exercise therapist. Patients who defecated one day prior to or on the day of TKRA surgery were included. Data collected from 72 subjects were analyzed using SPSS/WIN 21.0. Results: Time until first defecation after surgery was 2.4±1.1 days in experimental group, which was significantly shorter than the 3.5±0.9 days in control group (t=4.28, p<.001). Constipation assessment scale showed significantly lower points (t=2.55, p=.013) in experimental group (1.3±1.2) compared to control group (2.6±2.6). The experimental group and control group were 17.3±7.67 and 23.7±14.43, respectively, and the experimental group used less laxatives (t=2.83, p=.021). Conclusion: A defecation encouragement program was proved to be an appropriate nursing intervention for patients undergoing TKRA. This study confirmed that constipation is a nursing problem that can be sufficiently prevented if nurses are interested and encourage defecation.

The present experiments were carried out to reduce the population density of adult pine gall midge, Thecodiplosis japonensi,s UCHIDA et INOUYE, by means of spray the sticky agent C-4, on the ground, herbacious plantation and foliar leaf of pine trees at Sanbonli,. Anyang, Kyungido. And also the 3 periods of treatment, such as before 2 weeks( I ), before 1 week (II) from the peak emergence period and peak emergence period (III) were applied. The experimental results obtained were as follows. (1) The formula of selected sticky agent C-4 was $70\%$ of castor oil, $25\%$ of damar resin and $5\%$ of carnauba wax, and it showed the best both on stickiness and duration, and lower phytotoxicity to the host plant. (2) The reduction of population densities of the adult PGM were $68\%$ and 78f: in the G-I and G-II treatment plot respectively, which compared to control, on the ground spray. (3) And the reduction of population densities were $63\%$ and about $90\%$ in the P-I and P-II plot respectively when the agent was sprayed on the herbacious plantation. (4) The rates of gall formation were $32.8\%,\;40.8\%\;and\;59.4\%$ in the spray plots of F-I, F-II, and F-III respectively, and there was no significant difference among the upper, middle and lower parts of the treated host plant in the rates of gall formation. (5) The effective stage of sticky agent application were considered as before one week from the peak emergence period in tile all types of treatment.

In order to study the effects of probiotic and antibiotic on the performance of the chickens and the population of microfloras in the intestine, a feeding trial was conducted for a period of seven weeks. One hundred eighty hatched male chickens of layer attain were fed one of the following three experimental diets; nonmedicated control, antibiotic supplemented diet(virginiamycin 5 ppm) and probiotic supplemented diet. Birds fed probiotic supplemented diets were heavier and consumed more feed than those fed other diets but the differences were not statistically significant. Antibiotic supplemented group showed significantly (P〈0.01) better feed efficiency than other groups. Availabilities of dry matter, crude protein, crude fat, NFE, Ca and P were not significantly different between treatments but antibiotic supplemented group showed significantly(P〈0.05) lower availability of crude fiber than other groups. The weight of small intestine of the birds fed antibiotic supplemented diet was significantly (P〈0.05) lighter than those of other groups. The population of Bacillus subtilis and Lactobacilli in the intestinal content of the birds fed probiotic supplemented diet were significantly (P〈0.01) larger than those of other groups. On the other hand, the population of Coliforms in the probiotic group were significantly (P〈0.01) smaller than those in the nonmedicated control group.

Purpose : Cystatin C has been proposed for the assessment of glomerular filtration rate, being more accurate than creatinine determination. We measured serum cystatin C concentrations in the pediatric population, and analysed the correlation between cystatin C and glomerular filtration rate. Methods : Cystatin C and creatinine were measured by the particle enhanced nephelometric immunoassay and Jaffé method, respectively, in 276 children and adolescents without evidence of kidney disease. The glomerular filtration rate was estimated by Schwartz's formula. Results : The mean serum cystatin C concentration was significantly higher in infants under the age of 12 months than in older population. There was a negative correlation between cystatin C and age under 12 months, but not a significant change of cystatin C with age in children older than 12 months. For children older than 12 months, the reference range of cystatin C was 0.46-1.05 mg/L. On the other hand, there was a positive correlation between creatinine and age in the whole population. We also observed a positive correlation between estimated glomerular filtration rate and 1/cystatin C. Conclusion : The measurement of cystatin C is more practical than creatinine for estimating glomerular filtration rate in the pediatric population.

Seven aspects of attitude toward marriage in Korea are examined to better understand present and future marriage patterns. Also, various facets of current marriage practice are compared with attitudes. The study comprises three groups of roughly 600 women each, selected by random sampling from a rural, an urban, and a semi-urban area. A carefully designed and pretested questionnaire was checked for reliability by a reinterview in a 15% subsample. The great majority of Korean women support traditional attitudes that one must or should marry. The small group who recommend that one should not marry are mostly the very young or the never married, whose attitudes still may change. However, there are important and probably predictive shifts in favor of more individual decision, especially among the better educated, the young, and the more urban. Traditional reasons for marriage such as "custom" and procreation are ranked first by a majority, but there is a large shift to more contemporary or liberal desire for companionship and love, also primarily among the better educated, the urban, the young, and the never married. The traditional attitude that parents should have the sole or major role in mate selection is still held by a bare majority; the educated, urban, young, and never married are more liberal. Only 6% opt for each of the two extremes: That the parent alone or the respondent alone should decide. The remainder prefer one of the two middle-of-the-road positions where parent and child together decide. The proportions of respondents who classed specified criteria as moat important for selecting a husband, arranging the criteria in order from traditional to contemporary were: Lineage, etc., 23%; personal attributes, 40%; health and education, 27%; and love, 10%. The changing attitudes are suggested by the fact that love was ranked first by only 3% of the poorly educated rural poulation versus 23% of urban college level and 31% of the urban never married. There has been a substantial rise in the ideal age of marriage over the past twelve or more years, but there also is evidence that the ideal age is at or near a ceiling. Knowledge about legal age of marriage is minimal; the implications of this for proposed legislation are discussed. Three-fifthes to four-fifths of all respondents married husbands of the same religious, residential, and economic backgrounds as themselves. Almost all of them married men of the same or higher educational level. These evidences of traditional influences in mate selection are contrasted with the low priority given some of those items in earlier questions on reasons for marriage and criterion for selecting husband. Contrary to the expressed attitudes as to who should select the husband, we find that marriages of the study sample were stated to be arranged by parents alone in 62%; and in another 23%, the parents made the decision but asked the respondent's views. Such arrangements were most frequent among the rural, the less educated, and the older respondents and less common in the urban and more educated. The implications of these and related findings are discussed.

Data from this study support the View that the following factors are not sufficiently important in Korea to invalidate the relationships observed between age of marriage and fertility: (1) Premarital pregnancy and common law marriage, (2) shortening of birth intervals in late marriages, (3) adverse effects of very eary marriage in reproductive capacity, and (4) postponement of first pregnancy among early marriages. Thirteen variables which were considered to be potential predictors of fertility were studied to determine their influence on three indices of fertility. Age of marriage and family planning praetice are the strongest predictors and account for about 10% and 7% of the total variance, respectively. Seven other factors each account for an intermediate amount of variability; these are ideal number of children, rural versus urban study area, education, aspiration for daughter, index of exposure to mass media, economic index of respondent's home at survey, and residence before marriage. The remaining variables have no consistently significant relationship to fertility. Most of the relationships appear to be stable and consistent over time; others appear to be changing. The latter group include those variables which are associated with modernization indices of family planning practice, mass media exposure. and aspiration for daughters. Thus, the index of family planning practice is of limited significance for the $40{\sim}49$ age group but is the most important variable for the $20{\sim}29$ year women. The relationship is a direct one for the two age groups between 30 and 49 years which suggests that these groups already had high fertility when family planning services became available and that this high fertility then became an inducement to acccept contraception. The pattern of relationship is not yet clear for the $20{\sim}29$ year group. Similar interactions are observed for the other indices of modernity and are discussed. The thirteen variables together can account for a maximum of about 40% of the variance in the number of live births in the age group $30{\sim}39$, and for lesser amounts of variance in other age and fertility groupings.

Klinefelter's syndrome is a very important disease in gynecologic endocrinologic fields, because the patients with this karyotype complain of infertility, azospermia and ambiguous genitalia. Y chromosome is an important chromosome which determine genetic sex and the structure of gonad and genitalia. In this study, to elucidate the cytogenetic characteristics and clinical features of Klinefelter's syndrome and Y chromosomal abnormalities in Korea, we studied 303 cases of Klinefelter's syndrome and 11 cases of Y chromosomal abnormalities which were diagnosed by chromosomal analysis at the Cytogenetic Laboratory, Institute of Reproductive Medicine and Population, Seoul National University for 12 years from January 1984 to December 1996. The results of this study showed as follows: 1. In a total of 9275 cases, there were 303 cases (3.3%) of Klinefelter's syndromes, 11 cases (0.1%) of Y chromosomal abnormalities. 2. In 102 cases of patients showed typical clinical features of Klinefelter's syndrome, 101 cases (99%) of them were diagnosed to Klinefelter's syndrome in karyotyping. 3. In 303 cases of Klinefelter's syndrome, there were 277 cases (91.4%) of 47,XXY complement, 16 cases (5.3%) of mosaicism, 2 cases (0.7%) of 48,XXXY, 5 cases (1.7%) of 48,XXYY and 3 cases (1.0%) of 49,XXXXY. 4. In 303 cases of Klinefelter's syndrome, 284 cases (93.7%) of them were diagnosed after puberty and only 19 cases (6.3%) of them were diagnosed before puberty. 5. In 303 cases of Klinefelter's syndrome, there were 146 cases (48.2%) of patients with infertility-associated chief complaints, 101 cases (33.3%) of patients with typical clinical features of Klinefelter's syndrome, 22 cases (7.3%) of patients with ambiguous genitalia. 6. In patients with Klinefelter's syndrome, 48,XXYY and 49,XXXXY had serious symptoms such as mental retardation, developmental delay, Down syndrome-like features, congenital anomalies, but 48,XXYY and other mosaicisms had infertility-associated symptoms or ambiguous genitalia. 7. The 8 cases of polysomy Y (XYY complement) showed several serious symptoms such as Down syndrome-like features, mental retardation, fragile X syndrome-like feature, congenital anomalies, ambiguous genitalia which could be detected before puberty.
