We described a clinical, laboratory, and genetic presentation of a pathogenic variant of the CYP1B1 gene through a report of a case of primary congenital glaucoma and a trio analysis of this candidate variant in the family with the Sanger sequencing method and eventually completed our study with the secondary/incidental findings. This study reports a rare case of primary congenital glaucoma, an 8-year-old female child with a negative family history of glaucoma and uncontrolled intraocular pressure. This case's whole-exome sequencing data analysis presents a homozygous pathogenic single nucleotide variant in the CYP1B1 gene (NM_000104:exon3:c.G1103A:p.R368H). At the same time, this pathogenic variant was obtained as a heterozygous state in her unaffected father but not her mother. The diagnosis was made based on molecular findings of whole-exome sequencing data analysis. Therefore, the clinical reports and bioinformatics findings supported the relation between the candidate pathogenic variant and the disease. However, it should not be forgotten that primary congenital glaucoma is not peculiar to the CYP1B1 gene. Since the chance of developing autosomal recessive disorders with low allele frequency and unrelated parents is extraordinary in offspring. However, further data analysis of whole-exome sequencing and Sanger sequencing method were applied to obtain the type of mutation and how it was carried to the offspring.

Purpose: This study was implemented to investigate perceived illness intrusiveness in stroke patients by the characteristics of primary caregivers. Method: Retrospective cross-sectional survey design was used. The subjects were 225 stroke patients and their primary caregivers. Demographic variables, relationship variables, burden, depression and support were measured as primary caregivers' characteristics. Data were analyzed with SPSS win 14+. T-test, ANOVA and correlation test were used depending on variables. Result: Demographic variables such as age, gender, relation with patients, and living status were not related significantly with illness intrusiveness. But primary caregivers' burden, depression and support were related significantly with perceived illness intrusiveness of stroke patients. That is, burden, depression and quantitative support of primary caregivers were significantly positively correlated with perceived illness intrusiveness of stroke patients. On the other hand, qualitative support was negatively correlated with perceived illness intrusiveness. Conclusion: Primary caregivers' characteristics such as burden, depression and support were found to be correlated with stroke patients perception such as illness intrusiveness. So, it is recommended that nursing intervention targeting burden, depression and support of primary caregivers must be developed to reduce illness intrusiveness of stroke patients.

Purpose: To determine the knowledge and treatment compliance with hypertension, directions for the aspects of implementation, and related factors to patients with hypertension using Primary Health Cares and Private Clinics Hospitals. Method: General characteristics and High blood pressure-related properties(17 questions), Hypertension knowledge measures(20 questions), and Treatment Compliance(22 questions) were used. Result: 1. The patients of Private Clinics Hospitals had statistically significantly higher drinking habits than Primary Health Care centers. The patients of Private Clinics Hospitals had statistically significantly higher rate of no family history of hypertension than Primary Health Care centers. 2. Primary Health Care centers had statistically significantly higher knowledge of hypertension than Private Clinics Hospitals. Primary Health Care centers had statistically significantly higher treatment compliance than Private Clinics Hospitals. Conclusion: Both Primary Health Care centers and Private Clinics Hospitals are high medication compliance but low lifestyle compliance with hypertension. We need to recognize the importance of lifestyle compliance, to apply proper programs and to provide therapists' aggressive intervention.

Purpose: The purpose of this research is to enhance the effect of pictures on sexual education on primary school children which is one of the most crucial topics in health education and to evaluate how utilizing drawings can contribute to the development of school children's appropriate knowledge and attitude toward sexuality. Methods: This research followed the pre-test /post-test experimental and control group design. The selected school children of four classes at sixth grade in the H primary school in Gyeongi-do uijeongbu province had a pre-test about the knowledge and attitude toward sexuality. With the result of homogeneity data, three classes out of the four classes were chosen to be the subject of the post-test and these three groups took the "Sexual Education through Pictures." Results: After analyzing the data, average scores about the knowledge for class participants were higher than the non participants' (p =.000). Average scores about the knowledge of boys and girls who participated in class were higher than the non participants' (boys; p =.00, girls: p =.000). In addition, average scores about the attitude for class participants' were higher than the non participants' (p =.03), but there was not statistically significant among gender. Conclusion: From the results above, "Sexual Education through Pictures" proved to be a systematic and scientific method to develop a positive influence towards the knowledge and attitude of sexuality for primary school children of the sixth graders. These results show that the above teaching materials suggest an effective method to develop appropriate knowledge and attitude towards primary school children's sexual education.

The frequency window method has been extended to include strong coupling and multiple connections between the primary structure and the secondary structures. The rational polynomial expansion of the eigenvalue problem and the analytical methods for its solution are novel and distinguish this work from other eigenvalue analysis methods. The key results are the identification of parameters which quantify the resonance and coupling characteristics; the derivation of analytical dosed-form expressions describing the fundamental modal properties of the frequency windows; and the development of an iterative procedure which yields accurate convergent results for strongly-coupled primary-secondary structures.

Adsorption of cationic polyacrylamide dry strength resins onto the surface of papermaking fibers and fines is critical for their effective utilization. Since dry strength resins are frequently employed when recycled fibers containing a great deal of fines are used as a raw material, their adsorption characteristic onto the recycled fiber fines is of great importance. In this study, effects of recycling on adsorption characteristics of cationic polyacrylamide onto primary and secondary fines were examined. Never dried bleached hardwood kraft pulp was beaten and dried for recycling. In each recycling step the adsorption characteristic of a cationic PAM onto primary and secondary fines was evaluated by kjeldahl nitrogen analysis method. The influence of recycling on water retention value and carboxyl content along with the sheet density and tensile strength was examined. Secondary fines of never dried pulp adsorbed twice as much of C-PAM as the primary fines, however, the adsorption capacity of the secondary fines decreased rapidly during the course of recycling and showed lower adsorption capacily than primary fines.

Purpose: This study investigated the factors affecting the quality of life (QOL) of the primary caregivers of home health care patients. Method: The subjects were 110 primary caregivers of patients who were receiving home health care from two home health care centers affiliated with general hospitals in Seoul. Data collection was conducted using five questionnaires. Results: Positive relationships were evident between QOL and social support and perceived health status of the primary caregiver. Negative relationships were evident between QOL and burden and depression. Multiple linear regression analysis for QOL revealed that the most powerful influencing factor was social support. Social support, burden, and depression explained 34.3% of the variance. Conclusion: Burden, depression, and social support are related with QOL of primary caregivers of home health care patients. Nursing intervention strategies directed at this caregiver population are needed.

The Cognitive radio (CR) is evolving technology for managing the spectrum bandwidth in wireless network. The security plays a vital role in wireless network where the secondary users are trying to access the primary user's bandwidth. During the allocation the any malicious user either he pretends to be primary user or secondary user to access the vital information's such as credentials, hacking the key, network jam, user overlapping etc. This research paper discusses on various types of attack and to prevent the attack in cognitive radio network. In this research, secondary users are identified by the primary user to access the primary network by the secondary users. The secondary users are given authorization to access the primary network. If any secondary user fails to provide the authorization, then that user will be treated as the malicious user. In this paper two approaches are suggested one by applying elliptic curve cryptography and the other method by using priority-based service access.

The objective of this is to experimentally investigate the effect of mixed jet on the oxygen transfer characteristics with the primary nozzle area ratio of an annular nozzle ejector for the application of a microbial fuel cell. A direct visualization method with a high speed camera system was used to capture the horizontal mixed jet images, and a binarization technique was used to analyze the images. The clean water unsteady state technique was used for the oxygen transfer measurement. The air-water mixed jet discharging into a water tank behaved similar to a buoyancy or horizontal jet with the primary nozzle area ratio. It was found that an optimum primary nozzle area ratio was observed where the oxygen transfer performance reached its maximum value due to the decrease of air volume fraction and the increase of jet length and air bubble dispersion.
