The purpose of this study was to examine obstetrical & gynecological health status and body composition for married female immigrants. The participants were 154 immigrant women living in Busan. Data were collected from July 2008 to July 2009 using a questionnaire and a bioelectrical impedance analysis tool (Inbody 720) for analysis of body composition. Most subjects were in the normal range for body composition, but some of those who answered the questionnaire had experienced some gynecological problems such as dysmenorrhea, or irregular menstruation. There was a significant difference in experiences with in vitro fertilization, pregnancy and abortion according to age and in premensturaion syndrome, as well as differences in regulation of menstruation during the past year, leukorrhea odor, experiences in in vitro fertilization, and delivery and breastfeeding according to nationality. There were significant differences in body mass index and waist-hip ratio according to age, as well as differences in percent body fat, body mass index and waist-hip ratio according to nationality. There were also significant differences in body mass index and waist-hip ratio according to period of stay in Korea. Procreative care protocols concerning married female immigrants' characteristics should be developed.

Disruptive expression patterns of the circadian clock genes are highly associated with many human diseases, including cancer. Cell cycle and proliferation is linked to a circadian rhythm; therefore, abnormal clock gene expression could result in tumorigenesis and malignant development. The molecular network of the circadian clock is based on transcriptional and translational feedback loops orchestrated by a variety of clock activators and clock repressors. The expression of 10~15% of the genome is controlled by the overall balance of circadian oscillation. Among the many clock genes, Period 1 (Per1) and Period 2 (Per2) are clock repressor genes that play an important role in the regulation of normal physiological rhythms. It has been reported that PER1 and PER2 are involved in the expression of cell cycle regulators including cyclins, cyclin-dependent kinases (CDKs), and CDK inhibitors. In addition, correlation of the down-regulation of PER1 and PER2 with development of many cancer types has been revealed. In this review, we focused on the molecular function of PER1 and PER2 in the circadian clock network and the transcriptional and translational targets of PER1 and PER2 involved in cell cycle and tumorigenesis. Moreover, we provide information suggesting that PER1 and PER2 could be promising therapeutic targets for cancer therapies and serve as potential prognostic markers for certain types of human cancers.

This review described solvent-tolerant lipases and their potential industrial, biotechnological and environmental impacts. Although organic solvent-tolerant lipase was first reported in organic solvent-tolerant bacterium, many organic solvent-tolerant lipases are in not only solvent-tolerant bacteria but also solvent-intolerant bacterial and fungal strains, such as the well-known Bacillus, Pseudomonas, Streptomyces and Aspergillus strains. As these lipases are not easily inactivated in organic solvents, there is no need to immobilize them in order to prevent an enzyme inactivation by solvents. Therefore, the solvent-tolerant lipases have the potential to be used in many biotechnological and biotransformation processes. With the solvent-tolerant lipases, a large number insoluble substrates become soluble, various chemical reactions that are initially impossible in water systems become practical, synthesis reactions (instead of hydrolysis) are possible, side reactions caused by water are suppressed, and the possibility of chemoselective, regioselective and enantioselective transformations in solvent and non-aqueous systems is increased. Furthermore, the recovery and reuse of enzymes is possible without immobilization, and the stabilities of the lipases improve in solvent and non-aqueous systems. Therefore, lipases with organic-solvent tolerances have attracted much attention in regards to applying them as biocatalysts to biotransformation processes using solvent and non-aqueous systems.

The purpose of this study is to investigate the knowledge and attitude on tuberculosis for the nursing students in Daejeon, South Korea and Yanbien, China. A descriptive study was conducted. Data were collected from April to July of 2015 in each college and a total of 175 students assigned to 107 in Daejeon and 68 in Yanbien participated in the study. The data were analyzed by using the SPSS 21.0. There was no significant difference in knowledge and attitude on tuberculosis between the two groups. According to the results, in both groups, the mean score of knowledge and attitude was very low. In both groups, the correlation among knowledge, attitude and educational experience about tuberculosis was positive. In Daejeon nursing students, the attitude and gender explained about 15.3% and in Yanbien students, the attitude, grade explained about 40.2% in knowledge on tuberculosis. In Daejeon nursing students, the knowledge, health interest and educational experience explained about 23.5% and in Yanbien students, the knowledge and health interest explained about 23.9% in attitude on tuberculosis. Based on these findings, education which can guide nursing students to have correct information and positive attitude should be designed to manage tuberculosis infection. Therefore, it would be utilized in tuberculosis management education effectively for them.

This case report describes an uncommon treatment method for crown-root fractured incisor with immature root. A 7-year-old girl was referred for treatment of crown-root fractured maxillary central incisor. The fracture line extended to 1/2 of the total tooth length with incomplete root formation. The prognosis of crown-root fracture is usually poor and extraction is usually undertaken. But, in the mixed dentition, extraction of maxillary permanent incisor results in many complications, such as resorption of alveolar bone, poor esthetics, pronunciation and mastication. Conservative therapy in the permanent dentition comprises of few treatment modalities; supragingival restoration, gingivectomy, orthodontic extraction of apical fragment, surgical extrusion of apical fragment with or without rotational replantation. However, in this case, these indications are not applicable, so intentional replantation with adhesive resin system is the treatment of choice. The tooth was followed-up for 12 months. Currently, there are no symptoms. Since this modality adopts the respective advantages of both intentional replantation and adhesive treatment, it might be the treatment of choice in cases of vertical crown-root fracture.

Purpose: This study was done to investigate the point prevalence of postpartum depression and its predictors during early postpartum in mother of preterm infants. Methods: Participants were 101 women, 2-3 weeks after delivery whose preterm babies were hospitalized in a neonatal intensive care unit. Data were collected from June 2010 to January 2011. The instruments included 'Edinburgh Postnatal Depression Scale', 'Prenatal depression', 'Subjective health status of infant', 'Medical staff support', and 'Husband support'. Collected data were analyzed using t-test, ${\chi}^2$-test, and multiple logistic regression with SPSS/WIN version 18.0. Results: The point prevalence was 86.1% that postpartum depression occurred during the early postpartum period in mothers of preterm infants. Three significant predictors of postpartum depression in mothers of preterm infants were identified; 'Type of delivery (OR, 5.57; 95% CI, 1.25-24.77)', 'Subjective health status of infant (OR, 0.34; 95% CI, 0.16-0.70)', and 'Medical staff support (OR, 0.52; 95% CI, 0.28-0.97)'. Conclusion: The results indicate that postpartum mothers should be screened for postpartum depression early in the postpartum period and that, medical personnel should pay particular attention to mothers with a caesarean section and should help mothers of preterm babies to develop positive perceptions of their babies.

This article examined the trend of 125 empirical researches which were published in Jr. of Korean Social Welfare from the first issue to no. 33. in terms of theoretical and methodological orientations. The content analysis was employed for the purpose of the study. Since 1979, the number of empirical researches was in the trend of increasing. The findings from this research were as follows. 1) Among 166 authors, 96.4% were majored in social welfare. Also 6.0% were practitioners and the rest of them were in the position of professors or researchers. The outcome of lack of interdisciplinary co-work and researcher-practitioner co-work led the article to conclude that the nature of applied social science of social welfare was not so actively pursued in Korea. 2) It was almost impossible to find researches which studied same theme or employed same analytical framework. This meant that the work of re-verifying and proving the contray could not be done although it was essential for theory-building. In other words, the disciplinary of social welfare was far behind in the process of theory-building. 3) The methodology upon which most of researches were relied was quantitative methodology(92.8%). The article concluded 'paradigm shift' was not begun in the disciplinary of social welfare yet. 4) The study concluded that the particularity of empirical researches of social welfare in Korea was descriptive-configurative study. Whereas 65.5% of 125 empirical studies were descriptive-configurative, 25% were hypothesis - model test and only 6% causal analysis. 5) The most applied statistic models through the period from 1979 to 1997 were descriptive statistics such as frequency, chi square test, Pearson's r. More advanced statistics such as logit regression, probit regression, path analysis, covariance structure analysis were shown since 1990.

This study investigated the correlation between the participation in health-related decisions and self-care competency and the factors influencing self-care competence of patients with chronic disease. The participants were 518 patients with chronic illnesses who were admitted to a public health center. Using a structured-questionnaire, the data was collected from January 1, 2019 to 31, 2019. The data was analyzed using descriptive statistics, t-tests, ANOVA, Scheffé tests, Pearson correlation coefficients and multiple linear regression with the IBM SPSS/WIN 22.0 program. The mean scores on the participation in health-related decisions and self-care competency were 3.62±0.20 and 4.57±0.34, respectively. The main variables that distinguish significant differences between participation in healthcare decisions and self-care capabilities are gender, age, education level, diagnosis, and subjective health status. Self-care competency was positively correlated with the participation in health-related decisions (r=.66, p=.043). Factors influencing self-care competence were education (β=-2.23, p<.001), health concerns (β=0.14, p=.003), subjective health statues (β=2.57, p=.011), and age (β=-0.36, p=.048). The input variables explained .56 of self-care competence. The results of the study indicate that approaches focusing on enhancing the participation in health-related decisions could potentially improve self-care competency of patients with chronic disease.

This study is descriptive research to investigate frequency of performance, self-confidence and performance assessment scores of core nursing skills by 227 nursing students. As the result of this study, they who experienced more than 10times in clinical practice was V/S and they never experienced items such as transfusion, enema and T-tube care. For pre self-confidence, they had the highest V/S and the lowest transfusion. For post self-confidence, they had the lowest IM. As a result of the evaluation, oxygen therapy with nasal cannula was measured highest, and IM was measured lowest. Frequency of performance had positive correlations with self-confidence(r=0.414, p<.001) and performance assessment scores(r=0.322, p=.007). Self-confidence with performance assessment scores had positive correlation(r=0.281, p=.003). Study results suggested that clinical practice is carried out, non-invasive, simple measurements, and they had low self-confidence of the items with low frequency of performance, so convergency training methods to complement this point are needed.
