Central venous catheter (CVC) for long-term venous access is indispensable for various reasons including hyperalimentation, frequent blood sampling, frequent IV drug use in pediatric patients. We report clinical experience of surgical neonates in whom CVC was inserted primarily via great saphenous vein into suprarenal inferior vena cava. From March 2004 to March 2006, we performed CVC insertion via saphenous vein - contralateral side to main wound - into suprarenal inferior vena cava in surgeries of neonates. 2.7Fr or 4.2Fr, single lumen, tunneled Broviac catheters (Bard Access system, Inc, Salt Lake City, Utah) were used. Skin exit site of tunneled catheter was located in ipsilateral flank area just below edge lower rib. At the end of the procedure, location of the catheter tip was confirmed by plain radiography of abdomen. We retrospectively reviewed the admission records of the patients including nursing staff charts. Nine (50.0 %) patients were male and nine (50.0%) were female. Median gestational age was 38 weeks (range, 29-42 weeks) and median birth weight was 3,105 gm (range, 1,040-3,720 gm). Median age at catheter insertion was 38.5 days (range, 1-236 days). The purpose of CVC insertion was short-and long-term hyperalimentation in nine (50.0 %) patients. CVC insertion was performed in operation room under general anesthesia in sixteen (88.9 %) patients (in these cases, CVC insertion was performed just prior to concurrent operation) and neonatal intensive care unit (NICU) under local anesthesia with adequate sedation in two (11.2%). During the admission period (total catheter-indwelling time: 553 days), CVC functioned well without any significant side effects. Transient swelling of the ipsilateral leg (n=1, 5.6 %) and transient migration of catheter tip (n=1, 5.6 %) were noted, which did not affect function of the indwelled CVC. Mean catheter-indwelling time was 30.7days (range, 3-72 days). All catheters were removed electively except two mortality case. Complications, such as thrombosis, infection, kinking or extravasation of drugs, were not observed in our study period. Tunneled trans-great saphenous vein inferior vena cava catheters are not only comparable to cervical CVCs in terms of function and complication rates, but also very beneficial in selected patients, especially those in whom cervical approach is technically impossible or contraindicated.
This study was carried out with an objective to prepare the framework of conformity for the 21st century modern fashion, which is interactive with mankind, based on a position that the 21st century contemporary fashion with its amalgamating trend of diversified artistic forms may not be elucidated on a standpoint centering on one certain modality. The hybrid fashion trend of historical modality which provides freedom and satisfaction in creation of an individuals expressive power in expressing true desire of mans inside through man-centered thought of the times has made multifarious motives of the past and present fragmentary. It thus extracts inner divisions and the concept of consolidation through three-dimensional form. Modern fashion is newly interpreted by the material and details of high technologies. and is harmonized by mix and match with various expressions. By having it, it is being expressed together with many types of dresses and ornaments. Modern fashion is being expressed together with many types of dresses and ornaments by new interpretations with the material and details of high technologies and by being harmonized with mix and match with various expressions. The hybrid fashion design trend of regional elements formed by stimuli and contacts of diverse local culture by globalization of network that was achieved by scientific technologies of the contemporary information society has disintegrated varied boundaries in the conventional culture by the latest communication technology-new media on the basis of newly created culture. The fact that regional elements could be expressed as if they were interrelated without each being deprived of originality may be explained with an interpretation on pluralism. The hybrid fashion design trend of cultural aspect, which manifests in the background of scientific technological culture as it transcends the societal-cultural boundaries based on the de-centralization theory of Frederic Jameson, has supplemented the imperfect meanings through conversional correlation with other forms and internal program changes. The middle stratal and polyhedral characteristics are seen as each cultural element is dismantled and reassembled by application of 'multiple-time point expression'. Design forming method is not to bring destruction from outside, but to embrace instability and chaos through radical dismantling of the inside. and to pursue diversity and openness. Thus. it is implemented by an approach that takes the role of design process. In communication of discontinuity, continuity was dismantled through forms of mixing, overlap, perversion, insertion and coincidence.
Background: Acute promyelocytic leukemia (APML) is characterized by the reciprocal translocation t(15;17) (p22;p12) resulting in the PML-$RAR{\alpha}$ fusion gene. A dual diagnostic and follow up approach was applied including cytogenetic demonstration of the t(15;17) translocation and detection dg PML-$RAR{\alpha}$ chimeric transcripts by molecular means. Purpose: Conventional cytogenetics involving bone marrow is beset with high probability of poor metaphase index and was substituted with phytohemagglutinin (PHA)-induced peripheral blood culture based cytogenetic analysis as a diagnostic & follow up modality in APML patients of Kashmir (North India). Both qualitative (RT-PCR) and quantitative (Q-PCR) tests were simultaneously carried out to authenticte the modified cytogenetics. Materials and Method: Patient samples were subjected to the said techniques to establish their baseline as well as follow-up status. Results: Initial cytogenetics revealed 30 patients (81%) Positive for t(15;17) whereas 7 (19%) had either cryptic translocation or were negative for t(15;17). Two cases had chromosome 16q deletion and no hallmark translocation t(15;17). Q-PCR status for PML-$RAR{\alpha}$ was found to be positive for all patients. All the APML patients were reassessed at the end of consolidation phase and during maintenance phase of chemotherapy where 6 patients had molecular relapse, wherein 4 also demonstrated cytogenetic relapse. Conclusions: It was found that PHA-induced peripheral blood cytogenetics along with molecular analysis could prove a reliable modality in the diagnosis and assessment of follow up response of APML patients.
Small hydropower is the one of the cleanest one among new and renewable energy with less green house gas emissions. Recently, the necessity of developing small hydropower is emerging since its remaining potential resources in this country are abundant. However, a survey or research on the small hydropower development has been hardly performed since the 1990#s. These circumstances encourages a systematic approach for the small hydropower development. The purpose of this study is to propose a methodology of the location analysis for developing small hydropower. To this end, constraint and location criteria with weights are established and quantification method of each factor is presented. Especially, the analysis procedure is established on the basis of GSIS. Also the study focus on raising the objectivity and precision of analysis by developing system model with automatic search. The proposed methodology is applied to Bochung stream in Keum Riverbasin. The result selects the four and two locations of dam type and run-of-river type respectively. This study will be beneficial to the future activation of small hydropower development as a fundamental work.
Recently, the $2^{nd}$ generation genome map of the Korean cattle (Hanwoo) has been constructed by comparison of the nucleotide sequence of the Korean cattle BAC clones with whole genome sequence of the bovine data-base (B_tau 2.1 build). The objective of this study was to update the $2^{nd}$ generation genome map of the Korean cattle using the similar approach. The nucleotide sequence of the Korean cattle BAC clones utilized in the construction of the $2^{nd}$ generation map was compared with the newly released bovine data-base (B_tau 3.1 build) to generate the $3^{rd}$ generation map. While, 5,105 BAC clones were localized on bovine chromosome in the $2^{nd}$ generation map, a total of 9,595 BAC clones, which spans about 37.27% of the bovine chromosome after eliminating the overlapping sequence among the clones, have been mapped on the bovine chromosome in the $3^{rd}$ generation map. Further analysis of the nucleotide sequence of the BAC clones will allow us to develop map and facilitate to pinpoint the genes that are important for the improvement of the performance in this cattle breed.
This study investigated relative explanation of social support, ego-resiliency and stress coping strategies to help adaptive coping style of school-dropout adolescents under stress situation. To this end, 101 school-dropout adolescents were surveyed by visiting and requesting the outofschool youth supporting project, youth detention center, and adolescent protective and treatment facilities in Daejeon, Cheongnam, and Chungbuk. As analysis methods, descriptive statistical analysis, pearson's correlation, and hierarchical analysis were conducted and the research results are as follows. First, stress coping strategies showed positive relationship with social support and ego-resiliency. Second, a variable that showed greater explanation power for stress coping strategies was the environmental variable, the social support. Third, it was identified that there was greater explanation power when the environmental variable, the social support, and the personal variable, the ego-resiliency, were put in at the same time for stress coping strategies. According to the result, this study implies that schools, community, national policy effort and systemetic approach are required as well as improvement of personal coping capabilities in order to overcome difficulties school-dropout adolescents face.
One-lung ventilation (OLV) is the isolation and selective ventilation of one lung field. OLV allows the collapse of lung lobes on the side of the thoracic surgical approach to facilitate observation of intrathoracic structures and to achieve lung immobility. OLV be achieved by endotracheal intubation with double lumen tubes or bronchial blockers. In this study, cardiopulmonary consequences of two-lung ventilation (TLV), OLV and Re-TLV (TLV after OLV) were evaluated in 5 dogs. The dogs were anesthetized with mask induction and maintained with isoflurane in oxygen. Tidal volume and respiratory rates were set to maintain end-tidal $CO_2$ at $40{\pm}2mmHg$ during instrumentation. Following instrumentation, the dogs were placed in right lateral recumbency and induced spontaneously respiration state. Effect of TLV on hemodynamic and pulmonary variables were recorded. Then, the left bronchus was obstructed by endotracheal intubation with double lumen endotracheal tube to achieve OLV state and recording was continued. After OLV, double lumen endotracheal tube was extubated, and standard endotracheal tubes was intubated again. In this study, spontaneous OLV caused significant decrease in $PaO_2$, arterial oxygen saturation, mixed-venous oxygen saturation, and increase in $PaCO_2$. Especially, a significant elevation in $PaCO_2$ and respiratory acidosis were remarkable findings. So spontaneous ventilation in OLV affected gas exchange and hemodynamic function.

The objective of this study is to determine the structural relationships among the infant's temperament, father's involvement in child-rearing, and the infant's social and emotional behavior. To this end, research was conducted with 330 parents of infants aged 1 and 2 in 55 day care centers located in J city and I city, Jeollabukdo. Frequency analysis, reliability analysis, correlation analysis, confirmatory factor analysis, and structural model equation analysis were conducted using SPSS 21.0 and AMOS 21.0. First, the results of the structural model equation analysis showed that the infant's temperament had a negative correlation with leisure and guidance, while it had a positive correlation with activity and impulsivity, which are external manifestations of their social and emotional behavior. Father's involvement in child-rearing had a negative correlation with the adaptability and mood aspects of the child's temperament, and also with general anxiety, an internal aspect of his or her social and emotional behavior. Social and emotional behavior had a positive correlation with the approach avoidance aspect of the infant's temperament. Second, according to the results of the analysis of the route between the variables, infant temperament was found to be a significant route, having a statistically negative correlation with father's involvement in child-rearing. The results of this study showed that infant's temperament and father's involvement in child-rearing had effects on the infant's social and emotional behavior, and suggested the importance of having a proper understanding of the educational implications of the father's involvement in child-rearing, in terms of its effects on the infant's social and emotional behavior.
In the IOT social environment, which emphasizes the convergence of science and technology and emotion, this study aims to explore the experience and meaning of the experience while participating in the design convergence class based on the operation of the Learning community of Chinese graduate students majoring in design. To this end, an implementation study was conducted by visualizing various research problems using a design-based inquiry method for 12 graduate students attending T University. The design-oriented convergence class was conducted in a small group with content that was deepened into a visual strategy by the expression technique given by the external environment and the learner's own inner motivation. In order to express the perspective and intention of the research problem in the research, the convergence design research expressed using various visual strategies such as metaphorical use and analysis of visual data in the research process and sensory approach to the research problem was presented in a form that expresses the creative thinking process. As a way of exploration, the teaching method of presenting results based on various experiences suggests changes in new teaching formats, practical knowledge sharing by instructors, and community participation by learning participants.
The purpose of this study is to deeply explore the communication process with team members perceived by team leader. To this end, in-depth interviews were conducted with 10 team leaders, and analyzed according to the grounded theory research method procedure suggested by Strauss and Corbin. As a results, a total of 51 concepts, 17 subcategories, and 8 categories were derived. As a causal condition, the concept of 'contemplating and reinterpreting communication necessary for the organization' was derived, and the central phenomenon was 'intentional effort made in parallel with work and private conversations'. The contextual condition was 'recognizing the need to cope with environmental changes', and the mediating condition was 'self-reflection and self-coaching time' was derived. The action/interaction strategy was conceptualized as a communication process with task-oriented coping, conflict resolution coping, and relationship promotion coping, and was confirmed as 'recognizing virtuous cycle communication within the organization' as a result of interaction with the central phenomenon. As a result of analysis of the team leader's communication process, the effort stage, approach stage, coping stage, and cycle stage were shown. As a result of the type analysis, task-oriented coping was a facilitator, conflict resolution coping was a supporter, and relationship promotion coping was a considerate. This study is an empirical study on how the corporate team leader perceives and expresses communication in the relationship with the team members.
