The main objective oh this paper is to perform an empirical analysis on the relationship between various marketing activities and financial performance of Korean hospitals. A survey was conducted through structured questionnaire for 495 hospitals, and data from 218 hospitals were utilized in the final analysis. (response rate : 44%) Survey items include general characteristics of the hospitals (size, type, location), degree of competition, financial performance, marketing organization/ budget, and level of various marketing activities in service development, access improvement, promotion, and pricing. We examine descriptive statistics of the response scores on marketing activities to evaluate the current status of marketing management of Korean hospitals, compare the results across hospital size, type and location, and perform regression analysis to investigate the relationship between marketing and financial performance. Major findings are as follows : 1) About 46% of the responding hospitals gave marketing departments although they are named as 'planning' or 'PR' departments, and the marketing budget on average represents 1.74% of the total expenditures. 2) Average level of marketing activities is calculated to be about 3.32 on 5-point scale, meaning that Korean hospitals implement their marketing programs 'somewhat actively'; however, the scores on the areas of marketing planning and strategy are relatively low. 3) Large hospitals tend to be more active in marketing than small hospitals, and public hospitals' activities in marketing are not lower compared to private hospitals. 4) Level of overall marketing activities is positively related with financial performance measured by various financial indicators except for profitability, implying that marketing is successful in revenue generation but needs to be more cost-effective. Also, when the marketing variables are separately included in the regression, no significant relationship is found, which means that various marketing activities are more effective when they are collectively implemented.

Background: Medicolegal disputes are increasing in practical medicine. Acne is a common problem but is usually related to cosmetic problems such as acne scars. Medications or procedures related to acne could lead to medical malpractice. Objectives: To analyze medical litigation associated with acne or acne scar in South Korea. Methods: Acne-related judgements were searched using the Supreme Court of Korea’s Written Judgment Management System based on the keywords “acne” or “acne scar.” Results: Eleven cases were selected as litigated cases of acne or acne scar. Eight cases (72.7%) were related to acne scar and three (27.3%) were related to acne. Treatment modalities such as peeling (n = 6), laser treatment (n = 3), photodynamic therapy (n = 1), and antibiotic (n = 1) resulted in lawsuit. Claimed sequelae of the treatment were hyperpigmentation (n = 5), scar worsening (n = 5), erythema (n = 3), skin bumps (n = 1), and liver transplant (n = 1). Eight cases (72.7%) were awarded to the plaintiff, and the others were dismissed. The average awarded amount was 16,801,324± 24,452,486 (mean±standard deviation) Korean Won. Conclusion: Various treatments for acne or acne scar can cause medical disputes. Unnecessary litigation could be prevented if simple measures such as history taking, choosing proper procedure, and adequate management after the procedure along with sufficient informed consent were performed.

Aims: Chronic Hepatitis C Virus (HCV) infection increases the risk for progressive liver disease, hepatocellular carcinoma and negatively impacts the patient’s quality of life. HCV treatment is evolving with direct acting antivirals but IFN based therapy has been the standard of care for many years and remains available in some countries. The MOSAIC study aims to characterize patients with chronic HCV infection and assess the impact of IFN-containing treatment on health-related quality of life, work related productivity and health care utilization. Methods: MOSAIC is an international prospective multicenter observational study that has been conducted in 20 countries. Consecutive patients with chronic HCV infection were enrolled and those who initiated an IFN based regimen were prospectively followed for 48 weeks. We report results from the Korean cohort Results: 100 patients were enrolled: 86 were treatment naïve and 14 were treatment experienced. 33 patients initiated an IFN based regimen: 6 patients started IFN + RBV, 26 patients started Peg-IFN + RBV, none started Peg-IFN + RBV + DAA and 1 patient received other treatment. Among the treated cohort, demographic and disease characteristics were the following: the mean age was 54.5 years; 14 patients were male. 14 had minimal or no fibrosis, 2 portal fibrosis, 3 bridging fibrosis and 6 patients suffered from cirrhosis. HCV Genotype distribution was as follows: genotype 1: 11; genotype 2: 19 and genotype 3: 3. Table 1 describes the results at baseline and changes over 4, 12 and 48 weeks and end-of-treatment (EOT) for the quality of life and work productivity outcome measures (EQ-5D-5L, HCV-PRO and WPAI). Conclusions: Results from the Korean cohort of the MOSAIC study show a moderate trend for deterioration of health-related quality of life and work productivity associated with IFN based treatment for patients with chronic HCV infection during treatment period.

목적: Demonstrate a new instrument, technique or procedure 방법: In this video, we showed how to remove huge ovarian tumors in sinlgel port laparoscopic surgery by SW KIM`s method. SW KIM`s method is the technique to put a huge ovarian tumor into a specially designed extremely large endopouch (XXXL: 30x30㎠sized) using two conventional laparoscopic needle holders and one laparoscopic grasper and gravity by changing the patient`s position. After identifying the infundibulopelvic and uteroovarian ligaments salpingooophorectomy including huge ovarian tumor was performed by LigaSure. And then ovarian tumor was located in the pelvic cavity by changing the patient`s position into reverse-trendelenberg position and a XXXL endopouch was inserted and un-rolled inside the abdominal cavity. To insert a huge tumor into the XXXL endopouch, the endopouch was opened in triangular shape. Bilateral apex of baseline of trianglular opening of the endopouch was hold by two needle holders and then the upper apex was hold by a grasper. After holding three point of endopouch opeing, the patient`s position was changed into deep trendelenberg postion, then the tumor came into the endopouch by gravity. While changing the patient`s position, 2 needle holders and a graspers were moved into the pelvic cavity from the abdominal cavity. Aftere identifying the tumor inside the endopouch, tumors could be removed through the single port opening site or transvaginally in laparoscopic hysterectomy case without spillage of ovarian tumor. 결과: The advantage of SW KIM`s method is to remove ovarian tumor without spillage in a single port laparoscopic surgery by putting it into the large endoscopic bag despite narrow space. 결론: Using a specially designed 30×30 cm sized XXXL Endopouch and SW Kim`s technique, huge ovarian tumors could be removed without spillage in single port laparoscopic surgery.

Kyoung Sik Park,Kyu Eun Lee,Do Hoon Ku,Su-Jin Kim,Won Seo Park2,Hoon Yub Kim3,,Mi Ra Kwon1,Yeo-Kyu Youn1 대한외과학회 2013 Annals of Surgical Treatment and Research(ASRT) Vol.84 No.6

Purpose: To evaluate the antiadhesive effects and safety of an oxidized regenerated cellulose (Interceed) after thyroidectomy. Methods: Seventy-six thyroidectomized patients were prospectively randomized into two groups with regard to the use of Interceed. We evaluated each group for their adhesive symptoms using four subjective and four objective items at the 2nd week, 3rd and 6th month after thyroidectomy. All patients were examined for vocal cord motility by indirect laryngoscope at each period. Results: Total adhesion scores at each postoperative follow-up period decreased with time, but were not significantly different in each group. The median score for swallowing discomfort for liquid was significantly lower in the Interceed group than in the control group 2 weeks after surgery. In addition, the severity of skin adhesion to the trachea was reduced in the Interceed group compared with the control group 6 months after surgery. During the study, there were no adverse effects or significant differences in postoperative complications between the groups. Conclusion: Interceed appeared to be safe and effective in improving neck discomfort at early postoperative periods and preventing skin adhesion to the trachea 6 months after thyroidectomy.

Effects of seasonal variations on sediment-plume streaks from dredging operations

Kim, Nam-Hoon,Pham, Van Sy,Hwang, Jin Hwan,Won, Nam Il,Ha, Ho Kyung,Im, Jungho,Kim, Youngsung Elsevier 2018 MARINE POLLUTION BULLETIN Vol.129 No.1

<P><B>Abstract</B></P> <P>When mixtures of aggregates and water dredged from the seabed are discharged at the surface into the adjacent water from a barge, coarse sediments sink immediately and fine sediments are suspended forming a plume. Recently, elongated plumes of fine sediment were observed by satellites near a dredging location on the continental shelf. Such plume streaks were longer in certain conditions with seasonality than expected or reported previously. Therefore, the present work studied the appearance of sediment plume with field measurements and numerical simulations and explains the seasonally varying restoring force and thicknesses of the surface mixed layer resulting from the vertical density distribution near the surface, along with mixing by hydrodynamic process. The resulting mixtures, after vertical restoring and mixing with the surroundings, determine the horizontal transport of suspended sediments. A numerical model successfully reproduced and explained the results from field measurements and satellite images along with the seasonal variations.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Image captured by a satellite reported the unexpectedly long streaks of sediment plume from a dredging site. </LI> <LI> Elongations of plume depend on the seasonal variations of density differences between the mixtures and surface waters. </LI> <LI> While a long streak is observed, restoring force is too weak to sink the mixtures of sediment and water to the bottom. </LI> <LI> Seasonal variations of the surface mixed layer thickness significantly affect the development of the elongated plumes. </LI> </UL> </P>
