Purpose: This study was aimed to modify and adapt the previously developed, high-quality enteral tube feeding guidelines for the usage in clinical settings in Korea. Methods: Guideline adaptation process was undertaken according to the guideline adaptation manual version 2.0 developed by NECA (Kim, et al., 2011) and the standardized methodology for nursing practice guideline adaptation (Gu, et al. 2012). Results: The modified and adapted enteral tube feeding guidelines were consisted of 11 domains and 95 recommendations. The domains and numbers of recommendations in each domain were: 4 on general issues, 2 on enteral nutrition indication and discontinue, 6 on enteral nutrition device selection, 12 on enteral tube feeding device insertions, 3 on enteral nutrition formular and choices, 16 on enteral tube feeding start and progress, 20 on enteral tube feeding maintenance and management, 15 on monitoring enteral tube feeding administration, 10 on prevention of error, 5 on medication administration, and 2 on documentation and report. There were 16.1% of the recommendations marked as A grade, 17.8% of B grade, and 66.1% of C grade. Conclusion: The adapted enteral tube feeding nursing practice guideline is to be added to the evidence-based practice guidelines for fundamentals of nursing practice. The guideline is hoped to be disseminated to nurses nationwide in order to improve the efficiency of enteral tube feeding practice.

PURPOSE. This research evaluated clinical outcomes of two types of hydroxyapatite (HA)-coated implants: OT (Osstem TS III-HA, Osstem implant Co., Busan, Korea) and ZM (Zimmer TSV-HA, Zimmer dental, Carlsbad, USA). MATERIALS AND METHODS. The research was conducted on 303 implants (89 of OT, 214 of ZM), which were placed from January 16, 2010 to December 20, 2012. The prognosis was evaluated in terms of success rates, survival rates, annual marginal bone loss, and implant stability quotients (ISQ). The samples were classified into immediate, early, conventional, and delayed groups according to the loading time. RESULTS. Overall, there were no significant differences between OT and ZM in success rates, survival rates, and annual marginal bone loss, except for the result of secondary stability. OT showed $77.83{\pm}8.23ISQ$, which was marginally higher than $76.09{\pm}6.90ISQ$ of ZM (P<.05). In terms of healing periods, only immediate loading showed statistically significant differences (P<.05). Differences between OT and ZM were observed in terms of two indices, the annual marginal bone loss ($0.17{\pm}0.58mm/year$ < $0.45{\pm}0.80mm/year$) and secondary stability ($84.36{\pm}3.80ISQ$ > $82.48{\pm}3.69ISQ$) (P<.05). OT and ZM did not have any statistically significant differences in early, conventional, and delayed loading (P>.05). CONCLUSION. OT (97.75%) and ZM (98.50%) showed relatively good outcomes in terms of survival rates. In general, OT and ZM did not show statistically significant differences in most indices (P>.05), although OT performed marginally better than ZM in the immediate loading and 1-stage surgery (P<.05).

Purpose: This study was conducted to assess the incidence and characteristics of pressure ulcer in relation to the type of equipment and supplies(EnS) in intensive care unit(ICU). Method: By using secondary data analysis and descriptive investigation, 29 patients of pressure ulcers caused by EnS were examined from January 2013 to December 2015, at the advanced general hospital located in Gyeongsangnam-do. The subjects were aged 19 years and above and had been in the ICU for more than 3 days. The data were analyzed using the SPSS WIN 23.0 with frequency, percentage, and mean and standard deviation. Result: The incidence of EnS-related pressure ulcers was 3.71%. The EnS-related causes for pressure ulcers were endotracheal tube(31.03%), restraint(20.69%), and neck brace(10.34%). The longest use of EnS was oxygen tube(29 days). EnS that were possibly causing pressure ulcer for one day were restraint(upper extremities), endotracheal tube(oral and face), and oxygen mask(ear and nose). Conclusion: This study has been limited to secondary data analysis that may result in missing records of pressure ulcers related to EnS in ICU. However, the analysis of this research is expected to contribute to the development of nursing interventions to clarify the guidelines for the prevention of pressure ulcers related to EnS in ICUs.

Background: Full-thickness skin grafts (FTSGs) have been widely used after facial skin cancer resection, for correcting defects that are too wide to be reconstructed using a local flap or if structural deformation is expected. The preauricular, posterior auricular, supraclavicular, conchal bowl, nasolabial fold, and upper eyelid skin areas are known as the main donor sites for facial FTSG. Herein, we aimed to describe the effectiveness of using infraclavicular skin as the donor site for specific cases. Methods: We performed FTSG using the infraclavicular skin as the donor site in older Asian adults following skin cancer resection. Outcomes were observed for > 6 months postoperatively. The Manchester Scar Scale was used for an objective evaluation of satisfaction following surgery and scarring. Results: We analyzed the data of 17 patients. During follow-up, the donor and recipient sites of all patients healed without complications. Upon evaluation, the average Manchester Scar Scale scores for the recipient and donor sites were 7.4 points and 5.7 points, respectively. Conclusion: In general, conventional donor sites, such as the preauricular, posterior auricular, and supraclavicular sites, are widely used for facial FTSG because they achieve good cosmetic results. However, the infraclavicular skin may be a useful donor for facial FTSG in cases where the duration of time spent under anesthesia must be minimized due to a patient's advanced age or underlying health conditions, or when the recipient site is relatively thick area, such as the nose, forehead, or cheek.

Purpose : This study aimed to provide basic data for developing strategies to improve the nursing performance of nurses working in the intensive care unit by identifying the degree of their communication ability, job satisfaction, organization commitment, and nursing performance, and the relation between each of these variables in the intensive care unit by examining the factors affecting nursing performance. Methods : The participants comprised of 150 nurses working in the intensive care unit in two advanced general hospitals. Data were collected using structured questionnaires and analyzed using a t-test, ANOVA, the Scheffé test, Pearson's correlation coefficients, and multiple regression analysis using the SPSS/WIN 25.0 program. Results : Nursing performance of the participants was positively correlated with communication ability (r=.64, p<.001), job satisfaction (r=.26, p<.001), and organization commitment (r=.29, p<.001). Factors significantly influencing the participants' nursing performance included academic background (𝛽=.16, p=.032) and communication ability (𝛽=.50, p<.001). The explanatory power of these variables for nursing performance was recorded at 49.9% (F=19.04, p<.001). Conclusion : The use of various programs in the hospital and the development of effective communication ability with medical staff and other departments among nurses will help improve nursing performance, cooperation with other departments, and patient care.

Purpose: The purpose of this study was to provide basic data to understand the organizational culture of nurses by categorizing nurses' experience of coping with bullying in the workplace through Q methodology and analyzing the characteristics of each type, and to induce correct policy measures and interventions to create an atmosphere created in the nursing clinical field to be more advanced and positive. Methods: To form the Q population, focus group interviews were conducted with nurses working for more than six months at two general hospitals in Seoul and Gyeonggi. Interviews were conducted by 12 nurses introduced to participants who can provide researchers with a wealth of information on workplace bullying experiences without filtration. In addition, the Q population was extracted by reviewing the results. Based on the results derived from this, 38 Q statements in total were extracted. Forty clinical nurses were required to classify Q sample statements, and the data collected through this were analyzed using the pc-QUANAL program. Results: As a result of the analysis, a total of five types of clinical nurses' experiences of coping with bullying in the workplace were identified: 'tense emotion-based tolerance response,' 'positive thinking-based self-effort response', 'individualistic thinking-based passive response', 'support system-based emotional expression response' and 'active response centered on problem-solving'. Conclusion: The derived response types are expected to be guidelines for suggesting strategies to eradicate bullying in the workplace at the organizational level, individual level, prevention level, and organizational culture level.

Introduction: Third molar extraction is one of the most common procedures in oral and maxillofacial surgery. The impacted third molar causes many pathological conditions, such as pericoronitis, caries, periodontitis, resorption of adjacent teeth, and cyst or tumors associated with impacted teeth. Extraction is often considered the treatment of choice for impacted lower third molars. On the other hand, imprudent extraction of deeply impacted third molars can cause permanent complications, such as inferior alveolar nerve damage. Therefore, guidelines for the extraction of lower third molars should be set to prevent embarrassing complications. This study examined the indication and current trends of the extracted lower third molars in the dental hospital of a dental college. Materials and Methods: 557 extracted third molars were evaluated at the department of oral and maxillofacial surgery of Yonsei University. The chief complaint, diagnosis, age and degree of impaction were analyzed to determine the tendency for the extraction of asymptomatic lower third molars. Results: The percentage of asymptomatic third molars was 40.8%. In cases of full impacted tooth or full erupted tooth, the percentage of asymptomatic teeth was more than 50% (52.4% and 54.3, respectively). Among those partially impacted teeth, 73.1% of them showed symptoms, such as pain, tenderness and swelling. In terms of age, pericoronitis was evident at a younger age, and dental caries/periodontitis was the main cause of removal in those aged over 50. Twenty nine cases (1.6%) had teeth associated with pathological changes Conclusion: The incidence of pathological changes to the lower third molar was relatively low. Surgical extraction is recommended in cases of partially impacted teeth. In Korea, the incidence of asymptomatic third molar extraction was relatively higher than in European countries. More careful attention would be desirable to consider the risks and benefits of lower third molar extraction.

The newly revised 2018 Organ Injury Scale (OIS) has a similar format to the previous American Association for Surgery and Trauma (AAST) Emergency General Surgery Grading System, dividing the criteria for grading solid organ damage into three groups; imaging, operation, and pathology. The most significant alteration in the OIS system 2018 revision is the incorporation of multidetector CT (MDCT) findings of vascular injury including pseudoaneurysm and arteriovenous fistula. Similar to the previous OIS, the highest of the three criteria is assigned the final grade. In addition, if multiple grade I or II injuries are present, one grade is advanced for multiple injuries up to grade III. This pictorial essay demonstrates the MDCT findings of solid organ injury grades based on the 2018 OIS system.

Total 28 patients with resectable, locally advanced gastric cancer were entered in our prospective randomized study from June 15, 1988 to Sep. 15, 1990 in Yeungnam University Hospital. This study consisted of curative resection, IORT, external irradiation and combination of chemotherapy. Twenty-four of 28 patients were treated with single dose of 1500 cGy with 9 MeV election intraoperatively. External irradiation of $4300\sim4500$ cGy with 180 cGy per fraction, 5 days per week was started within 4th weeks of postoperative days. Various chemotherapy with or without external irradiation were added for reducing hematogenous and/or peritoneal dissemination and determination of complication of each arm. Duration of follow up was $4\sim31$ months. No serious complication related with radiation were reported compare to resection and chemotherapy only group. Although our follow up period is too short to draw any conclusion, IORT appears to improve local control, hopely further survival. Continuous follow up should be needed for evaluation of real therapeutic gain such as complication vs. improved survival.

BACKGROUND/OBJECTIVES: A pivotal role of oxidative stress has been emphasized in the pathogenesis as well as in the disease progression of Parkinson's disease (PD). We aimed at investigating serum levels of antioxidant vitamins and elucidating whether they could be associated with the pathogenesis and progression of PD. MATERIALS/METHODS: Serum levels of retinol, ${\alpha}$- and ${\gamma}$-tocopherols, ${\alpha}$- and ${\beta}$-carotenes, lutein, lycopene, zeaxanthin and ${\beta}$-cryptoxanthin were measured and compared between 104 patients with idiopathic PD and 52 healthy controls matched for age and gender. In order to examine the relationship between antioxidant vitamins and the disease progression, multiple group comparisons were performed among the early PD (Hoehn and Yahr stage I and II, N = 47), advanced PD (stage III and IV, N = 57) and control groups. Separate correlation analyses were performed between the measured antioxidant vitamins and clinical variables, such as Hoehn and Yahr stage and Unified Parkinson's Disease Rating Scale (UPDRS) motor score. RESULTS: Compared to controls, PD patients had lower levels of ${\alpha}$- and ${\beta}$-carotenes and lycopene. ${\alpha}$-carotene, ${\beta}$-carotene and lycopene levels were significantly reduced in advanced PD patients relative to early PD patients and were negatively correlated with Hoehn and Yahr stage and UPDRS motor score in PD patients. No significant differences were found in serum levels of retinol, ${\alpha}$- and ${\gamma}$-tocopherols, and other carotenoids between PD patients and controls. No significant correlations were found between these vitamin levels and clinical variables in PD patients. CONCLUSTIONS: We found that serum levels of some carotenoids, ${\alpha}$-carotene, ${\beta}$-carotene and lycopene, were lower in PD patients, and that these carotenoids inversely correlated with clinical variables representing disease progression. Our findings suggest that decreases in serum ${\alpha}$-carotene, ${\beta}$-carotene and lycopene may be associated with the pathogenesis as well as progression of PD.
