  • The purpose of this study was to identify the relationships among health promoting behaviors, Health Locus of Control(HLOC), and response patterns to HLOC in Korean elderly. The sample was composed of 162 healthy elderly ranging in age from sixties to eighties. The instruments for this study were modified Health Promoting Lifestyle Profile (45 items, 4 scales), and Multidimensional Health Locus of Control (18 items). For the in data analysis, SPSS PC$^{+}$ program was uilized for descriptive statistics, Pearson correlation, t-test, ANOVA and Stepwise multiple regression. The results of the study are as follows : 1. The total mean score for the HPLP was 2.411 (range 1-4), and the mean scores on the subscales were 3.324 for nutition, 2.709 for interpersonal support, 2.495 for exercise,2.225 for health responsibility, 2.205 for self actualization, 2.026 for stress management. 2. The mean scores for the HLOC in the elderly were HLOC-I : 23.531, HLOC-P : 21.914, HLOC-C : 18.667. 3. The response patterns of the HLOC identified eight types, pure internal, pure powerful others, pure chance, double external, believers in control, yea sayer, nay sayer and complex control. The “believers in control” was the largest group (22.8%), and “yea sayer” was the next largest group(17.9%). The “nay sayer”(5%) was the smallest group. 4. Demographic variables, such as education, economic status, religion and the perception of the health status showed strong connections to health promoting behaviors. 5. The HLOC-I and health promoting behavior were correlated positively(r=.165, P=.017), but the HLOC-P, the HLOC-C and the health promoting behavior were not correlated at the level of statistical significance. 6. There was not significant difference in health promoting behavior depending on the response patterns of the HLOC(F=1.171, P=.108). But, there were significant differences in two subscales of health promoting behavior exercise (F=3.279, P=.002), and stress management (F=3.165, P=.003). 7. Education, the perception of the health and economic status explained 21.0% of the variance for health promoting behaviors. These results suggest that several demographic factors are important factors in predicting the level of health promoting behaviors in elderly. So to enhance the health promoting behavior, nurses should use the different nursing strategies depending on the demographic characters of the elderly.

  • Precise Point Positioning (PPP) is an increasingly recognized precisely the GPS/GNSS positioning technique. In order to improve the accuracy of PPP, the error sources in PPP measurements should be reduced as much as possible and the ambiguities should be correctly resolved. The correct ambiguity resolution requires a careful control of residual errors that are normally categorized into random and systematic errors. To understand effects from two categorized errors on the PPP ambiguity resolution, those two GPS datasets are simulated by generating in locations in South Korea (denoted as SUWN) and Hong Kong (PolyU). Both simulation cases are studied for each dataset; the first case is that all the satellites are affected by systematic and random errors, and the second case is that only a few satellites are affected. In the first case with random errors only, when the magnitude of random errors is increased, L1 ambiguities have a much higher chance to be incorrectly fixed. However, the size of ambiguity error is not exactly proportional to the magnitude of random error. Satellite geometry has more impacts on the L1 ambiguity resolution than the magnitude of random errors. In the first case when all the satellites have both random and systematic errors, the accuracy of fixed ambiguities is considerably affected by the systematic error. A pseudorange systematic error of 5 cm is the much more detrimental to ambiguity resolutions than carrier phase systematic error of 2 mm. In the $2^{nd}$ case when only a portion of satellites have systematic and random errors, the L1 ambiguity resolution in PPP can be still corrected. The number of allowable satellites varies from stations to stations, depending on the geometry of satellites. Through extensive simulation tests under different schemes, this paper sheds light on how the PPP ambiguity resolution (more precisely L1 ambiguity resolution) is affected by the characteristics of the residual errors in PPP observations. The numerical examples recall the PPP data analysts that how accurate the error correction models must achieve in order to get all the ambiguities resolved correctly.

  • This study was done to compare the breast-feeding primiparas' perceptions of their babies with bottle-feeding primiparas' at 2-3 days after delivery. The subjects of this study included 42 breast-feeding mothers and 56 bottle-feeding mothers. Data were collected by using the Neonatal Perception Inventory(NPI) devised by Broussard (1963) and added by Lee, Ja Hyung(1986) from December, 1996 to June, 1997. The results of this study are as follows, 1. Primiparas' perceptions of their babies according to their general characteristics. 1) There was no significant difference in mothers' perceptions according to mothers' age and whether they have a job or not. 2) There was a difference in mothers' perceptions according to their educational level (P<0.1). 2. The comparisons of breast-feeding mothers' perceptions of their babies with bottle-feeding mothers'. 1) There was no significant difference in the two groups' perceptions of other babies 2) There was no significant difference in the two groups' perceptions of their own babies. (1) Breast-feeding mothes' general perceptions of their own babies were better than bottle-feeding mothers', but there was no significant difference between the two groups. (2) Breast-feeding mothers' perceptions about the basic needs of their own babies were better than bottle-feeding mothers', and there was a significant difference between the two groups (P<0.05). (3) Breast-feeding mothers'perceptions about the sense and motor abilities of their own babies were better than bottle-feeding mothers', but there was no significant difference between the two groups. (4) Breast-feeding mothers' perceptions about the necessary care of their own babies were lower than bottle-feeding mothers', but there was no significant difference between the two groups. 3) There was no significant difference between the two groups' positive-negative perceptions of their babies (1) 69% of breast-feeding mothers and 69.9% of bottle-feeding mothers had positive perceptions about general conditions, but there was no significant difference between the two groups (2) 57.1% of breast-feeding mothers and 46.4% of bottle-feeding mothers had positive perceptions about the needs of babies, but there was no significant difference between the two groups. (3) 50% of breast -feeding mothers and 48.2% of bottle-feeding mothers had positive perceptions about the sense and motor abilities of babies, but there was no significant difference between the two groups. (4) 57.1% of breast-feeding mothers and 60.7% of bottle-feeding mothers had positive perceptions about the necessary care for babies, but there was no significant difference between the two groups. 3. 54.8% of breast-feeding mothers tried to feed their own babies on the 1st day after delivery. 83.3% of breast-feeding mothers chose the feeding method for themselves. Only 9.5% of breast-feeding mothers took recomendations for breast-feeding from nurses. 78.6% of breast-feeding mothers had no chance to learn about breast-feeding. 69% of breast-feeding mothers complained about the difficulties of breast-feeding. The most serious problems were : 'insufficient milk supply', 'lack of knowledge about feeding technique' and 'problems with nipples'.

  • 본 연구는 내부노동시장 및 외부노동시장과 분절된 근로빈곤노동시장의 경로제약성이 취업과 취업의 질에 누적적인 영향을 미쳐, 장기간 근로빈곤노동시장에 머물게 함으로써 근로빈곤탈출을 저해하는 악순환의 고리가 되는지 분석하였다. 자료는 한국노동패널 $3{\sim}7$차이고, 분석방법은 Markov 이행확률과 이산시간분석을 활용하였다. 분석결과 우리나라 노동시장은 내부노동시장과 외부노동시장 그리고 근로빈곤노동시장의 삼중 구조로 이루어져 있었다. 근로빈곤유형은 최근으로 올수록 취업빈곤층은 계속 감소하는 반면, 비경활 빈곤층은 점점 증가하여 근로빈곤층의 주된 유형이 되었다. 근본적으로 빈곤층에 대한 노동수요가 부족하며, 빈곤층의 취업자체를 저해하는 노동시장의 구조적 장벽이 존재함을 볼 수 있다. 회귀분석에서는 근로빈곤노동시장 참여기간이 길어질수록 근로빈곤 이탈률이 감소하였다. 이는 한번 근로빈곤노동시장에 편입되면 그 굴레를 벗어나지 못하고 근로빈곤노동시장 내에서 폐쇄적으로 이동하여, 다시 빈곤으로 연결되는 악순환을 보여주는 것이다. 따라서 적절한 근로조건을 보장하는 노동수요 활성화정책과, 근본적인 노동시장구조 개혁 및 빈곤층 노동에 대한 부정적 사회인식과 차별완화 정책이 필요하다.

  • This study was designed to explore the effectiveness of education to improve self-care of stroke patients with three types of charactor health locus of control and constitution. A total of 56 patients were selected by convenience sampling at one oriental hospital. The teaching of self-care was conducted by the researcher. The self-care performance was measured for 10 days. The data were analyzed using t-test, ANOVA and Scheffe method as post hoc test. The results of this study are as follows : 1. The self-care performance by patients' characteristics : Age and education had impact on the self-care performance. The level of self-care performance of young and high educated patients was high, gender, religion, occupation, monthly income, and the paralyzed side, however, didn't have influence on the self-care performance. 2. The self-care performance of patients with three types of constitution : There was no statistical significance on the self-care performance of patients group by constitution. However, average score of self-care performance of patients with So-Um was high. 3. The self-care performance of patients with three types of health locus of control : There was no statistical significance on self-care performance of patient group by health locus of control. 4. The correlation between the constitution and the health locus of control : There was no statistical significance on the introverted and chance health locus of control of patients with three types of constitution. However, there was a statistically significant relationship between the powerful others health locus of control and So-Yang. Even though there was no statistically significant self-care performance of patients with So-Um, there was a clinical significance on the high score of self-care performance of patients with So-Um as compared with the self-care performance of the patients. The health locus of control didn't have influence on the self-care performance of patients. There was a statistically significant relationship between the powerful others health locus of control and So-Yang. Therefore, this study suggest the need to develop the nursing intervention to improve the self-care of stroke patients with the powerful others health locus of control and So-Yang, Furthermore, the longitudinal research is needed to determine the effectiveness of training to imp

  • This study is to provide evidence-based recommendations for the most-effective treatments of benign prostatic hyperplasia based on patient preference or clinical need, and to meta-analyze the Korean literatures for the development of BPH treatment guidelines. For these analyses, extensive literature searches (208 articles), with priority given to the Korean Journal of Urology, were conducted from 1960 to August, 1996. Meta-analysis, like all statistical analysis, has two main functions: data summarization (qualitative meta-analysis) and smoothing o. pattern recognition (quantitative meta-analysis). As well, critical reviews and syntheses with the mean and 90-percent confidence intervals for the likelihood were used to evaluate empirical evidence and significant outcomes of the BPH treatment literatures (106 articles). For this task, the Methodologic Panel for BPH Guidelines was composed of multidisciplinary experts in the field. The results of the study were summarized as follows: For all that watchful waiting is an appropriate treatment strategy for the majority of patients with prostatism, we couldn't find the Korean literatures which carried this article. The literatures on alpha-1-adrenergic receptor blockers provide no evidence to suggest that any one alpha blocker is more effective than another. The finasteride reduces the size of the prostate, on average, and leads to a small yet perceptible reduction in sysptoms. Of all treatment options, prostate surgery with transurethral resection of the prostate (TURP), transurethral incision of the prostate (TUIP), and so on, offers the best chance for symptom improvement. However, surgery also has the highest rates of significant complications. Therefore, surgery need not always be a treatment of last resort. Balloon dilation of the prostatic urethra is clearly less effective than surgery in relieving symptoms, but it is associated with fewer complications. Emerging technologies for treating BPH include lasers, coils, stents, thermal therapy and hyperthermia. Established technologies will also be reanalyzed as results of new trials are reported. Although this study has some limitations due to lacking for good quality literatures, ' it provides a cornerstone for our medical research. It represents the most current scientific knowledge regarding the clinical epidemiology including treatment of BPH. It will be revised and updated as needed.

  • Compomer is composed of matrix and filler : matrix is made of the combination of resins and polycarboxylic molecules that are light-cured, and a filler is a glass component which is capable of ion-release. The resin content of compomers produces polymerization shrinkage which can adversely affect marginal adaptation. Pretreatment is a fundamental step which is treated with conditioner or primer in the use of these materials. Microleakage of restorative materials has been investigated mostly by dye penetration method. Dye penetration method was not quantitative and not measured repeatedly. Fluid filtration method, introduced and developed by Pashley's group, has been extensively used for 20 years for research purpose to understand the physiology of dentin, as well as the effects of various restorative treatments on dentin permeability. It permits quantitative, nondestructive measurment of microleakage in a longitudinal manner. The purpose of this study was to evaluate the change of dentin permeability according to the process of compomer restoration. In this study. Cl V cavities were prepared on buccal surface of thirty extracted human molars. The prepared cavities were etched by 37% phosphoric acid. The experimental teeth were randomly divided into three groups. Each group was treated with following materials Group 1 : Prime & Bond NT/Dyract AP, Group2: Single Bond/F2000 compomer, Group 3 : Syntac Single Component/Compoglass. The bonding agent and compomer were applied for each group following manufacturers information. Dentin permeability of each group was measured at each process by fluid filtration method; Step 1 : preparation(smear layer). Step 2 : etching(smear layer removal), Step 3 : applying the bonding agent, Step 4 : filling the compomer. Dentin permeability was expressed by hydraulic conductance ($\mu\textrm{l}$ min$^{-1}$cm$H_2O$$^{-1}$). The data were analysed statistically using One-way ANOVA and Sheffe's method. The results were as follows : 1. Dentin permeability differences between each process were significant except between step 1 and step 2(p<0.01). 2. Dentin permeability after removal of smear layer was highly increased(p<0.01). 3. In most case, decrease of dentin permeability was obtained by applying bonding agent(p<0.01). 4. Dentin permeability differences among the experimental groups were not significant(p>0.05). 5. None of compomers used in this study showed perfect seal at the interface.
