Purpose: This is for analyzing the recent citations from papers enrolled in the Journal of Korean Academy of Nursing and understanding correct marking of references. Method: Targeted 2,334 references in 93 articles introduced from Feb. 2002 to Dec. 2002 which are applied current contribution rules of the Journal of Korean Academy of Nursing. Result: 1. 25 references are quoted per article and particularly foreign journals are most frequently quoted. Among foreign journals, Nursing Research is most frequently used. The Journal of Korean Academy of Nursing is also mostly referred material among national journals. 2. The retrieval rate is prove to be 1,539(83.8%) and 267(11.7%) are without errors and the other 2,022 have at least more than one error regardless of frequency. 3. Major error rate of periodical publication is 484(36.8%) and most occurred in the inconsistency of titles between articles and references. 4. Foreign journals have much more errors than national ones concerning periodical publications. Conclusion: Correct citation and marking of references can be achieved through strict reviewing process by authors, editors, publishers and paper investigators. In consequence, it is expected that these processes can cause improvement of quality in impact factor and papers.
Objective : A modified surgical technique of posterior cervical foramintomy called posterior cervical inclinatory foraminotomy (PCIF) was introduced in previous preliminary article. PCIF allows better preservation of facet joint and capsule than conventional techniques. The authors conducted a study to investigate long-term outcomes of PCIF. Methods : We retrospectively reviewed demographic, radiologic, and clinical data from the patients who underwent PCIFs at our institution. Criteria included a minimum of 48 month follow-up and PCIFs for patients with radiculopathy from foraminal stenosis (C2-T1; single or multilevel) with persistent or recurrent root symptoms despite conservative treatment for more than 3 months. Patients who had undergone previous cervical operation were excluded. The visual analogue scale (VAS) score was used for clinical follow-up, and radiologic follow-up was performed to compare the changes of cervical sagittal alignment, focal angle and disc-space height of treated segment. Results : The PCIFs were performed between April 2007 and March 2011 on 46 patients (32 males and 14 females) with a total of 73 levels affected. The average duration of follow-up was 74.4 months. Improvements in radiculopathic pain were seen in 39 patients (84.7%), and VAS score decreased from $6.82{\pm}1.9$ to $2.19{\pm}1.9$. Posterior neck pain also improved in 25 patients (71.4%) among 35 patients, and VAS score decreased from $4.97{\pm}2.0$ to $2.71{\pm}1.9$. The mean disc-space heights of treated segment were $5.41{\pm}1.03mm$ preoperatively and decreased to $5.17{\pm}1.12mm$ postoperatively. No statistically significant changes in cervical sagittal alignment, focal angle were seen during the follow-up period (Cox proportional hazards analysis and Student t-test, p>0.05). Conclusion : The PCIF is highly effective in treating patients with cervical spondylotic radiculopathy, leading to long-lasting relief in pain. Long-term radiologic follow-up showed no significant spinal angular imbalance.
There are two different groups of vessels which have a duty to avoid the other vessel in the Collision Regulations; one is a vessel to keep out of the way and the other is a vessel not to impede the passage. The definition and duty of a vessel not to impede was clarified by IMO's adoption of rule 8(f) of 1972 COLREG in 1987 revision. However, the Korean government has not inserted rule 8(f) of 1972 COLREG into Korean national collision regulations to date and so the definition and application for a vessel not to impede has not been discussed in even academic circle. Recently Korean Supreme Court rendered a verdict on a collision case involved with a vessel not to impede. The writer expresses his view on the duty of a vessel not to impede and criticizes the Supreme Court's judgment, consulting with foreign scholar's article and the relevant IMO's papers.
In order to improve organizational performance, organizations should make a knowledge management system to share, distribute, and create related knowledge effectively in the operational process. It is not too much to say that organizational performance depends on the level of network and networking for the use of knowledge among the agents. Theoretically, a web portal is known as a useful instrument not only to link among the actors who have a specific interest and purpose but also to promote social networking which creates new knowledge relevant to user's environment. In the context, this article explored policy implications of building and operating government portals by analysing the efficacy of the "Innovative Portal", which the Korean government had opened to diffuse its innovation activities and to improve organizational innovation capacities in 2005, in innovation process from the knowledge management perspective. In particular, this study tried to identify how did the "Innovation Portal"influence network and networking of innovation knowledge using hyperlink network analysis method.
Using a Rheometries Dynamic Analyzer (RDA II), the dynamic viscoelastic properties of a semi-solid ointment base (vaseline) in large amplitude oscillatory shear flow fields were measured over a temperature range of $25{\sim}45^{\circ}C$ and the linear viscoelastic behavior in small amplitude oscillatory shear flow fields was investigated over a wide range of angular frequencies. In this article, the nonlinear viscoelastic behavior was reported from the experimentally obtained data and the effect of temperature on this behavior was discussed in detail. In addition, the angular frequency and temperature dependencies of a linear viscoelastic behavior were explained. Finally, the applicability of a time-temperature superposition principle originally developed for polymeric materials was examined using a shift factor. Main results obtained from this study can be summarized as follows : (1) At very small strain amplitude region, vaseline shows a linear viscoelastic behavior independent of the imposed deformation magnitudes. Above a critical strain amplitude $({\gamma}_{0}=0.1{\sim}0.2%)$, however, vaseline exhibits a nonlinear viscoelastic behavior ; indicating that both the storage modulus and dynamic viscosity are sharply decreased with increasing deformation magnitude. (2) In large amplitude oscillatory shear flow fields, an elastic behavior (storage modulus) has a stronger strain amplitude dependence and begins to show a nonlinear behavior at a smaller strain amplitude region than does a viscous behavior (dynamic viscosity). (3) In small amplitude oscillatory shear flow fields, the storage modulus as well as the loss modulus are continuously increased as an increase in angular frequency and an elastic nature is always superior to a viscous behavior over a wide range of angular frequencies. (4) A time-temperature superposition principle can successfully be applicable to vaseline. This finding allows us to estimate the dynamic viscoelastic behavior of vaseline over an extraordinarily extended range (11 decades) of angular frequencies inaccessible from the experimentally measured range (4 decades).
In this study for the prosthesis of the spatial and directional sensation for the blind, an ultrasonic scale system and an electronic compass system were developed. The ultrasonic scale utilizes 40 ㎑ sound for the detection of distance to the barrier and the spatial information is transferred to the blind by various sound interval, which is proportional to the distance. The electronic compass utilizes a magnetoresistor bridge for the detection of the magnetic field strength of earth in horizontal plane. The information for the direction of the earth's north is transferred by tactile stimuli by a vibrating motor band around upper head. Detection distance of the ultrasonic scale is ranged from 0.065 to 3.26 meters, and the detection angle resolution of the electronic compass is about 22.5 degrees. The integrated system of the ultrasonic scale and the electronic compass was developed. Distance information is converted to the location of the tactile stimulation along the clockwise direction by a vibrating motor according to the distance installed around upper head of the blind. The intent of this article is to provide an practical prosthetic tool of spatial and directional sensation for the blind. Daily practice of this system will improve the usefulness of this system.

Background Surgical ablation for locally advanced breast cancer results in large chest wall defects, which can then be managed with local flaps or skin grafts. The purpose of this article is to evaluate the outcomes of three types of local skin flaps. Methods Among 25 local flaps in 24 patients, 6 were bilateral advancement (BA) flaps, 9 were thoracoabdominal (TA) flaps, and 10 were thoracoepigastric (TE) flaps. Clinical outcomes were compared including complications, the need for a secondary surgical intervention, and the timing of adjuvant therapy. Results The mean defect size was $436.2cm^2$. Two patients with TA flaps and 6 patients with TE flaps developed distal flap necrosis, and skin grafts were needed to treat 2 patients with TE flaps. Radiation was administered to the BA, TA, and TE patients after average postoperative durations of 28, 30, or 41 days, respectively. The incidence of flap necrosis tended to be higher in TE patients, which lead to significant delays in adjuvant radiation therapy (P=0.02). Conclusions Three types of local skin flaps can be used to treat large chest wall defects after the excision of locally advanced breast cancer. Each flap has its own merits and demerits, and selecting flaps should be based on strict indications based on the dimensions and locations of the defects.
Purpose: The importance of the deformities in alar - columellar complex has been underestimated in Asian ethnic groups for the last decades. Fortunately, with increasing familiarity of the open rhinoplasty techniques, the anatomic details of the nasal tip have been pointed up. Definitely, having an interest and demand for improving the sub - normal relationship between the alar rim and columella are indebted for such growing of knowledge about nasal tip anatomy. However, it is true that any single procedure is not settled as versatile and fully confident modality to correct the retracted notching of the alar rim. With this article, I should like to propose another useful option for treating retracted ala. Methods: The author has tried to correct alar rim retraction by means of: (1) Triangular onlay septal cartilage graft on the lower lateral cartilage with the medial end fixed to the anterior surface of the lateral crus(Alar extension graft), (2) Inserting lateral end of the alar extension graft to the vestibular skin pocket in the form of a finger - in - groove, (3) using the vestibular skin in the form of an advancement flap, and (4) using the soft shield graft to prevent possible visible step - off of the alar margin. Results: The author applied an alar extension graft to 16 patients in order to correct a retracted ala for the last 27 months (August, 2003 - October, 2005). The distances from alar rim to long axis of nostril were improved to be within 2 mm in all of the cases, and also the shape of the alar rim changed to a round form. Nostril asymmetry (6%) in one case, temporary palpable step - off (18%) in three cases, temporary visible step - off (6%) in one case, and temporary paresthesia of the tip (25%) in four cases were observed. Conclusion: The alar extension graft is simple and efficacious. It does not need donor sites other than the operative field, and its results are predictable. In particular, since it may give structural intensity to a weak lower lateral cartilage, it may be preferentially used for the correction of a retracted ala that arises from hypoplastic lower lateral cartilage. Moreover intensified lower lateral cartilage also improves the esthetic shape of lobule.
Objectives : This article aims to find how effective the art therapy is on the improvement of the self expression and the interpersonal relations with others, as medium for verbal communication of schizophrenic patients. Methods : The subject of this study was one schizophrenic patient who had been treated with drugs for five years in W university hospital, as well as counseled by an art therapy oo counsel office in J city. The art therapy had been performed the total 25 sessions, fifty minute per session, one session per week, from November 28 in 2008 to April 27 in 2009. The test was by HTP. Results : The results of this study are as follows: First, in the pretest of HTP, the subject showed a little lethargy, painting very simple house-shaped figures and too simple rectangular figures corresponding to those painted by 4 or 5-year-old children. In the post-test, however, the structures of houses were described concretely and three-dimensionally, and the descriptions of people were changed into concrete figure, by which we could see the improvement effect on the self expression and the interpersonal relations. Second, in the earlier stage, there was little verbal self expression, and little self respect, staring into space and showing passive attitude without positive assertion and expression. In the later stage, however, there were positive assertion and expression, even showing sense of humor. Lastly, in the earlier stage, there were few interpersonal relations. In the later stage, however, eye contacts and the interpersonal relations were increased during conversation and in the art work process, respectively. Conclusions : These results suggest that the art therapy can be effective on improvement of the self expression and the interpersonal relations with others, as medium for verbal communication of schizophrenic patients.
Purpose: To develop a probability-based differential diagnosis for pediatric acute liver failure (PALF) based on age and socioeconomic status of the country of origin. Methods: Comprehensive literature search using PubMed, EMBASE, and SCOPUS databases was performed. Children 0-22 years of age who met PALF registry criteria were included. Articles included >10 children, and could not be a case report, review article, or editorial. No language filter was utilized, but an English abstract was required. Etiology of PALF, age of child, and country of origin was extracted from included articles. Results: 32 full text articles were reviewed in detail; 2,982 children were included. The top diagnosis of PALF in developed countries was acetaminophen toxicity (9.24%; 95% CredI 7.99-10.6), whereas in developing countries it was Hepatitis A (28.9%; 95% CredI 26.3-31.7). In developed countries, the leading diagnosis of PALF in children aged <1 year was metabolic disorder (17.2%; 95% CredI 10.3-25.5), whereas in developing countries it was unspecified infection (39.3%; CredI 27.6-51.8). In developed countries, the leading diagnosis in children aged >1 year was Non-A-B-C Hepatitis (8.18%; CredI 5.28-11.7), whereas in developing countries it was Hepatitis A (32.4%; CredI 28.6-36.3). Conclusion: The leading causes of PALF in children aged 0-22 years differ depending on the age and developmental status of their country of origin, suggesting that these factors must be considered in the evaluation of children with PALF.
