Purpose: To analyze the result of the accurate open reduction of acromioclavicular (AC) joint and pin fixation, coracoclavicular (CC) screw fixation without CC ligament repair for AC joint injuries. Materials and Methods: Between January 2000 and December 2003, seventeen cases with at least one year follow-up among twenty-one cases underwent operation for AC-CC ligament injuries. A transverse incision approximately 5 cm in length was made over the clavicle, and the AC joint was reduced accurately. Under the image intensifier, a cannulated screw and washer were inserted for the CC ligament. Two Steinman pins were inserted for the AC joint and the AC ligament was repaired with nonabsorbable suture. Gentle passive range of motion was begun postoperative 2 weeks. The pins were removed at $6{\sim}8$ weeks and the screw was removed at $10{\sim}12$ weeks. The results were evaluated by a distance between AC and CC joints on plain films and ASES score at last follow-up. Results: At the last follow-up, there was no limitation of motion and average ASES score was 96($86{\sim}100$ points). There was no failure showing over 5 mm difference of distance compared to opposite side on the plain films. Seven cases had the skin damages and local infection due to pin migration and three cases showed the loosening of CC screw. Conclusion: We could have satisfactory results by accurate reduction of AC joint and simple pins and screw fixation for AC-CC ligament injuries.

Purpose: To report our experience with nine cases of pathologic synovial plica on radiohumeral joint which symptom of painful snapping elbow was improved by arthroscopic resection. Materials and Methods: Between 1999 and 2004, 43 cases of elbow arthroscopy were performed by one surgeon. Eight patients with nine cases showed pathologic synovial plica in conjunction with snapping or posterolateral elbow pain. The mean age of eight patients (man: 7, woman: 1) was 29 years (range $16{\sim}56$ years). All patients had a trial of conservative treatment at least six months (range $6{\sim}16$ months). The diagnosis was confirmed before surgery in six cases and at the time of surgery in three cases. Pain, snapping, and subjective results were evaluated at least 12 months in the average(range $12{\sim}24$). Results: All patients showed a hypertropic lateral synovial plica with local synovitis. Seven of them had an associated lesion of chondromalacia on radial head. One of them was associated with radiocapitellar arthritis and had a wrapping over the radial head. Six patients experienced improved posterolateral pain at the end of study (VAS<1). However, the other two patients had occasional pain with activity. One of them persisted with mechanical symptoms, which was treated with additional arthroscopic procedure. Conclusion: Synovial plica in elbow should be considered as an important entity of common elbow disease, especially when pain in the lateral aspect of the elbow with a snapping sensation during motion is featured in patients. The arthroscopic resection seems to be safe and efficient in the short and long term treatment of plica in the elbow joint.

This study examined the accessibility of emergency rooms according to the population density and distance in Daegu Metropolitan City to help improve the quality and emergency medical accessibility problems in Daegu Metropolitan City. To observe the geographical requirements, the number of population in eup, myeon, dong, available emergency, and available emergency compared to the population were mapped through the S-GIS of Statistics Korea to visualize the data based on the 3km radius. To determine the difference in accessibility to emergency rooms for each district in Daegu Metropolitan City, the data were analyzed by ANOVA and Scheffe. According to the average number of emergencies available in Daegu Metropolitan City within a 3-kilometer radius were 5.7 in Jung-gu, 5.0 in Nam-gu, 1.6 in Buk-gu, 0.4 in Dong-gu, 2.4 in Seo-gu, 0.9 in Suseong-gu, 3.5 in Dalseo-gu, and 0.1 in Dalseong-gun; there was a statistically significant difference (p<.001). The available emergency within a 3km radius and available emergency per 1,000 people were concentrated in the center. Therefore, it may be necessary to institute an urban emergency medical network by establishing a point that serves as an intermediate hub to provide emergency medical care to citizens far from the center.

This study researched the toothbrushing behavior and perception of oral health condition in accordance with the use of cafeteria, 280 Students of 28 high schools in Daegu and Gyeongbuk to identify the relationship between cafeteria use and oral health. and then obtained statistically significant results like below. Toothbrushing after meals and snacks was high with female students and Grade3. Rinsing mouth for ten times or more after toothbrushing was high with female students and private car while the use of oral care products was high with female students, Grade3, and private car. The whole average frequency of using cafeteria was 2.26 while the perception of oral health condition was 3.44. The frequency of using cafeteria was high with Grade2, before time for school, and lots of allowance. The perception of oral health condition was high with male students, school bus, and lots of allowance. The frequency of using cafeteria in accordance with toothbrushing behavior was high with toothbrushing for longer than three minutes(2.45) while the perception of oral health condition was high in case when using oral care products(3.32). In the results of multiple regression analysis to understand the influence of perception of oral health condition, general characteristics, and toothbrushing behavior on the frequency of using cafeteria, it was analyzed like Y(frequency of using cafeteria)=-952+.393(perception of oral health condition)- 1.721(time for school)+ .991(allowance)+ 1.124(duration of toothbrushing). Based on the results above, it would be necessary to establish the educational system to continuously practice the correct oral health care education in school.

A bacterial strain, designated B301^T and isolated from raw chicken meat obtained from a local market in Korea, was characterized and identified using a polyphasic taxonomic approach. Cells were gram-negative, non-motile, obligate-aerobic coccobacilli that were catalase-positive and oxidase-negative. The optimum growth conditions were 30℃, pH 7.0, and 0% NaCl in tryptic soy broth. Colonies were round, convex, smooth, and cream-colored on tryptic soy agar. Strain B301^T has a genome size of 3,102,684 bp, with 2,840 protein-coding genes and 102 RNA genes. The 16S rRNA gene analysis revealed that strain B301^T belongs to the genus Acinetobacter and shares highest sequence similarity (97.12%) with A. celticus ANC 4603^T and A. sichuanensis WCHAc060041^T. The average nucleotide identity and digital DNA-DNA hybridization values for closely related species were below the cutoff values for species delineation (95-96% and 70%, respectively). The DNA G+C content of strain B301^T was 37.0%. The major respiratory quinone was Q-9, and the cellular fatty acids were primarily summed feature 3 (C_16:1 ω6c/C_16:1 ω7c), C_16:0, and C_18:1 ω9c. The major polar lipids were phosphatidylethanolamine, diphosphatidyl-glycerol, phosphatidylglycerol, and phosphatidyl-serine. The antimicrobial resistance profile of strain B301^T revealed the absence of antibiotic-resistance genes. Susceptibility to a wide range of antimicrobials, including imipenem, minocycline, ampicillin, and tetracycline, was also observed. The results of the phenotypic, chemotaxonomic, and phylogenetic analyses indicate that strain B301^T represents a novel species of the genus Acinetobacter, for which the name Acinetobacter pullorum sp. nov. is proposed. The type strain is B301^T (=KACC 21653^T = JCM 33942^T).

In early August 1978, a huge red tide occurred off Chilcheon Is, , at the mouth of Jinhae Bay. It expanded rapidly into the central part and then soon covered all the bay except the innermost part of the bay. After staying for a week it disappeared, and thereafter several small scale red tides partially occurred and disappeared untill the end of August. It differed from the red tides hitherto recorded from this bay in respect of the dominant plankter, the geographical extent and the severe damaging effect to local oyster resources. During the red tide period, nevertheless, no oyster damage was found. In September, however, oyster mortailty was found from all rafts and longlines in the bay. Except the inner most part of the bay the oyster farms were completely destroyed. Of the oyster Production in the winter 1978, $96\%$ of an estimated yield of 5,879 tons (shucked meat) was lost and it was estimated to be 2,275 million won, equivalent to $US\$$ 4.55 million. The dominant species was a dinoflagellate, Ceratium fusus and it constituted about $45\%$ of the total phytoplankton. Cell count showed $7.0\times10^4\;cells/\iota$ and chlorophyll-a, $50mg/m^3$ during red tide peak. No oxygen was found ill the bottom waters in September. Sulphides in bottom waters and in the superficial mud increased to 15 and 8-fold respectively in September compared with July ana August. Precipitation from January to May of 1978 was about a third in comparison with the past ten years average but rainfall ill June was two and half-fold more than normal year, and thereafter drought persisited till September Air and water temperatures were also higher, and sunny days continued for a long time without strong winds. Therefore, water was calm for a long time after the red tide extinguished. The result indicated that the occurrence of the Ceratium red tide occurred in that year which was characterized by the combination of the formation of almost anoxic bottom water before the red tide occurrence, high air temperature and the calmness after a great quantity of rainfall in June. The mass mortality of oysters was presumed not to be directly related with the red tide but with the depression of dissolved oxygen in the environmental waters at the bottom due to settling of the red tide organisms.

Heavy snowfall disasters are the third most serious natural disasters, after typhoon and heavy rainfall disasters, in terms of economic disaster damage in South Korea. The average annual economic damage of heavy snowfall disasters was approximately eighty-eight billion won during the period of 2005-2014. In spite of significant economic damage, there have been few economic studies regarding heavy snowfall disasters in South Korea. The objective of this research is to identify the association between economic damage of heavy snowfall disasters and damage effect factors of snowfall amounts, snowfall days, population densities, and non-urban area ratios using a regression analysis model. Economic damage data sets of heavy snowfall disasters during the period of 2005-2014 were obtained from the Natural Disaster Yearbook published by the Ministry of Public Safety and Security. Weather-related data sets, such as snowfall amounts and snowfall days were collected from the Korea Meteorological Administration. Demographic and urban data sets, including population densities and non-urban area ratios, were provided by the Local Government Yearbook. Outcomes of this study can assist with heavy snowfall disaster management policies of South Korea.

This study provides basic data needed to improve the working environment of the first class emergency medical technicians, in order to decrease their job stress and increase their job satisfaction. Job stress and satisfaction were compared and analysed in emergency medical technicians who were working for 119 rescue and hospitals at the time when twenty-one years had passed after the initial training of emergency medical technicians in order to identify differences between 119 rescue and hospitals, and their advantages and disadvantages. The subjects of the study were 182 first-class emergency medical technicians who were working in twenty-eight 119 rescue centers and fourteen national and local emergency medical centers in Gwangju, Jeollanamdo and Jeollabukdo. The study subjects were interviewed by questionnaire. For statistical analysis, SPSS/WIN 20.0 was used, and the results were analysed with chi-square, t-test, ANOVA, and ANCOVA testing. There was no significant difference in job stress between the subjects working in 119 rescue centers (2.92) and those working in hospitals(3.01). The satisfaction score of fire-fighting workers was 2.98 and that of hospital workers was 2.54. Hospital workers' satisfaction was significantly lower (p<0.001). The score of hospital workers' pay satisfaction was the lowest($2.07{\pm}0.62$). The job stress decreased and job satisfaction increased with decreasing monthly average number of patients(p<0.001), increasing monthly income(p=0.047), and more frequent holidays they had(p<0.001), the less. For less job stress and higher job satisfaction, welfare conditions both at 119 rescue and hospitals should be improved. 119 rescue centers should develop violence prevention measures and offer resting places for emergency medical technicians. Hospitals should pay more attention to the yearly pay increase rate and stability in employment types.

This study provides fundamental data in order to obtain improved medical services and competitiveness by analyzing the satisfaction level of patients receiving inpatient services at general hospitals. Data from self-administered surveys distributed to inpatient subjects at local general hospitals was collected from 09/19/2011 to 09/30/2011. Firstly, the results of 320 surveys show that the average level of satisfaction from inpatient services was 3.25 (maximum 4.0). Secondly, the results from general characteristics and satisfaction from medical care provider services showed that there is a statistical significance regarding medical treatment, health condition, the number of times admitted to the hospital, and hospital environment including hospital admittance/release proceeders. Also the satisfaction with other services is statistically significant with regards to age, medical treatment, health condition, and the number of times admitted to the hospital. Thirdly, there is a statistically significant positive correlation between inpatient services and levels of satisfaction. Finally, from the analysis of factors influencing inpatient satisfaction showed that physician services and other services significantly affect satisfaction. In conclusion, in order to increase inpatient levels of satisfaction the workforce involved medical treatment of patients need to be retained and a variety of programs need to be in operation that will satisfy patients while they stay in the hospital. Further research is expected.

Aside from political leaders' popularity rates and the stock exchange index of business firms, ordinary people are highly interested in aspects of daily life, such as housing, income, health, family, food, human relations and work. Cross-national opinion polls on daily-life satisfaction were carried out in Japan, South Korea, Thailand, Hong Kong, Macao, the Philippines, India, Myanmar, Taiwan, China, Malaysia and Pakistan in the fall of 2013 and winter 2014. The percent difference index (PDI) is formulated as the sum of two positive responses (satisfied and somewhat satisfied) minus the sum of two negative responses (dissatisfied and somewhat dissatisfied). Percent difference indices are given according to society and daily-life aspects. For our analysis to go beneath national average and to go beyond national borders, two lines of analysis are carried out. First, the distance between the level of satisfaction of the top and bottom quartiles is given for each society and according to each of the daily-life aspects. Second, the regional sum of satisfaction of the top quartiles and bottom quartiles are shown crossed by daily-life aspects. In this article we confine ourselves to preliminary comparative description and analysis. More solid and deep comparisons will be carried out by local polling leaders of 12 Asian societies in the succeeding issue of the Asian Journal of Public Opinion Research. Nevertheless, two key threads stand out from this preliminary comparisons. First, social relations (family and human relations) stand out as most satisfied aspects of life in most of twelve societies. Second, the need to go beneath national averages and beyond national borders in analyzing cross-national surveys is confirmed. The comparability and validity of cross-national surveys with varying sampling method and survey mode are briefly discussed toward the end of the article.
