  • A 42-years-old man was referred to our department due to his hemoptysis. Chest CT showed a cavitary lung lesion in the apical segment of the RUL and an anterior mediastinal mass. The patient underwent wedge resection for the cavitary lesion and complete resection for the mediastinal mass. The pathologic finding was Paragonimus Westermani infestation in both the lung and thymus. The abdomen CT taken postoperatively showed an inflammatory mass involving the transverse colon and a small nodular lesion around the descending colon, which strongly suggested paragonimiasis. Postoperatively, the patient took Praziquantel for 2 days and he was discharged without any complications. There was no evidence of recurrence for the last 2 years.

  • Shigella is one of the most prevalent pathogens for the diarrhoeal diseases in the developing countries. One hundered and six strains of shigella were isolated from January 1980 to August 1981 at the dept. of clinical pathology, Han Yang Medical Center. Subgroups of these strains were identified as one strain of S. dysenteriae, 98 strains of S. flexneri and 7 strains of S. sonnei. None of S. boydii was observed. Sex ratio, male to female was 48 to 58. Age distribution disclosed 6 cases under one year, 11 cases one to under 2 years and 21 cases(19.8%) two to under 3 years. Subtotal of 0 to 9 years showed 64 cases(60.4%). Susceptibility for antibiotics of these strains revealed dibekacin 100%, sisomicin 100%, amikacin 98.1%, cefazolin 97.2%, tobramycin 97.1%, gentamicin 95.2%, colistin 93.0%, minocycline 89.6%, kanamycin 83.0%, carbenicillin 18.9%, streptomycin 18.9%, tmp-smz 8.6%, ampicillin 2.8% and chloramphenicol 1.9%. Patterns of resistance to sulfa, streptomycin, chloramphenical and tetracycline have already started at the early part of 1960 decade. Although ampicillin was highly sensitive to shigella at the end of 1960 to the early part of 1970 decade, this study has disclosed high resistance to the strains. New antibiotics such as amikacin, cefazolin, dibekacin, gentamicin, and tobramycin have revealed highly sensitive to these strains, however, multiresistance for those antibiotics will be shown to be prevalent in this country within several years, where it is probably related to the unrestricted sale and use of antibiotics in man.

  • Purpose: This study was done to evaluate effectiveness of deep breathing exercise as a postoperative intervention to prevent pulmonary complications. Methods: A search of databases from 1990 to 2012 was done including MEDLINE, EMBASE, CINAHL, Cochrane Library and eight Korean databases. Ten studies met eligibility criteria. Researchers trained in systematic review, independently assessed the methodological quality of selected studies using the Cochrane's risk of bias tool. Data were analyzed using RevMan 5.2 program. Results: Among ten RCTs in four studies, deep breathing exercise was compared with an instrument using interventions such as incentive spirometry, in the other four studies deep breathing exercise was compared with non-intervention, and in last two studies bundles of interventions including coughing and early ambulation were assessed. A significant difference was found between deep breathing exercise group and non-intervention group. The odds ratio (OR) of occurrence of pulmonary complications for deep breathing exercise versus non-intervention was 0.30. However, there was no significant difference between deep breathing exercise group and incentive spirometry group (OR=1.22). Conclusion: Deep breathing exercise is vital to improving cost-effectiveness and efficiency of patient care in preventing postoperative pulmonary complications. For evidence-based nursing, standardized guidelines for deep breathing in postoperative care should be further studied.

  • Manufacture of nancomposites has simple process for developing nanocomposites due to the increasing applications using nanofillers. This work studied nanofiller coated glass fiber for reinforcing material with good wetting and conductivity and the morphology of nanofiller coated glass fiber was analyzed by FE-SEM. The durability of reinforced glass fiber was investigated with different shapes of nanofillers using sonication rinsing method. Fatigue test was performed to evaluate the adhesion of reinforcing interface and stability of nanofiller coating layer for single fiber reinforced composites. Apparent modulus and conductivity of nanofiller coating layer were evaluated to realize multifunctional of nanocomposites. Fiber type of nanofiller was better than plate type due to better cohesion between fiber and nanofillers. At last, the stability of fiber type nanofiller of coating layer has better durability and conductivity than plate type case.

  • The Hapchon Dam, located upstream of the Hwang River, Korea, was constructed in December, 1988. Due to the lack of storage of water, the dam gate has not been operated during last ten years. Thus, a new ecosystem has been established at the downstream part of the dam. This is not a common phenomenon which can be found elsewhere in the country. The present study investigates the effect of flow regime change on the river morphology and vegetation cover in the downstream river reach after the dam construction. The analysis of flow regime is carried out, and the changes in bed elevation and in channel cross sections are examined. Site investigations including tree ring tests are also performed. The increase in the vegetation cover is estimated by comparing aerial photographs taken before and after dam construction.

  • In this study, two commercial mating disruptors were compared in terms of disruption of Oriental fruit moth, Grapholita molesta, male orientation, in which a new dispenser type, $SPLAT^{(R)}$, was compared with a current dispenser type, $Isomate^{(R)}$-M ROSSO. For this assessment, the last three year field monitoring data were analyzed for the efficacy of Isomate type dispenser. Then two commercial dispensers were compared in different localities with sub-locality replications during identical monitoring period from mid February to late August. There appeared to be four adult population peaks, in which the overwintering population size was positively correlated with the following reproductive population sizes. Isomate type dispenser effectively suppressed G. molesta populations during all growing seasons with some annual variation in its efficacy. Between two dispensers, SPLAT type was much effective. The difference in their efficacy may be caused by the difference in composition of major pheromone component.

  • The world's food production systems are becoming an area of great concern for both human and ecological health. Research has identified that one of the greatest threats to sustainability is conventional industrial agricultural systems and the high energy and material cost they require to function. The organic food movement is contributing as promising alternative to the current dominant model. Over the last 50 years it has developed into the most visible brand for a healthier and more environmentally sustainable food system. However, to achieve its full potential there are still a number of hurdles which must be overcome to make organic products a more viable and appealing option for consumers. This paper provides an overview of key research that has been conducted on why consumers are buying organic products, what they are buying and what is preventing them from purchasing more. It concludes that the key challenge is for the organic food movement to convince existing consumers of the superior 'value' of its products. In addition there are a number of methodological issues associated with analysing the market for organic products as well as issues of limited distribution, intermittent availability and high prices that are currently preventing increases in sales. Recognition and management of these barriers could contribute to more effective targeted research into consumer food purchasing motivations and subsequently the development of more sophisticated marketing strategies that assist in maintaining integrity with consumers and fending off challenges from conventional as well as other complementary food systems such as local food movement. And finally to achieve these market growth strategies the organic food movement will need to cope with its diverse constituency - ranging from global corporates through to local production and consumption - and provide attractive opportunities to individuals and business at all stages in supply chain whilst retaining credibility with government to ensure ongoing policy support.

  • The purpose of this research was to analyze questioning types of the Korean Elementary Mathematics Textbook in grade 3 and suggest the direction of questioning strategies for enhancing creativity in mathematics lessons. For the research, the researcher analyzed questioning types of the 3rd grade mathematics textbook and the changes of the questions compared with the questions in the previous textbooks. The author suggested the following recommendations. First, the questioning strategies of the revised mathematics textbook tends more to enhance students' creativity than the previous ones did. Second, teachers need to know the students' level of mathematics before starting their mathematics lessons because teachers can provide more effective differentiated questioning to the students. Third, students can response tuned to their level of mathematics if they meet with open-ended questions. It is desirable to develop good open-ended questions to fit students' abilities. Last, teachers should provide opportunities for students to share their own mathematical thinking. In risk-free environment, students can willingly participate at debating over mathematics proofs and refutation. Teachers should make efforts to make the classroom norm or culture free to debate among students, which leads to enhancement of students' creativity or mathematical creativity.

  • The purpose of this study is to examine closely the aesthetic characteristics featured in dandy's costume. Dandy was term used on for a man excessively fond of and overly concerned with clothes, exemplified by Beau Brummell, Lord Byron, and count d'Orsay, who greatly in gluenced men's fashions in England and France. In the late eighteenth and early nineteenth century George Brummell, the prototype of the dandy, made upper-class English country clothes, especially riding clothes, into the height of men's fashion in the city. In the early 1800s the alterations he made, particularly with regard to fit and cut, established these as the critical signifiers in men's dress. Brummell's style, particularly for day, was essentially restrained and disciplined, and set a standard for sober discretion, appropriateness and taste which governed men's clothing until well into the twentieth century. The aesthetic characteristics expressed in dandy's dress are the aristocratic superiority of mind, the restrained beauty in absolute simplicity, and the pursuit of the individual beauty. Brummell's kind of dandyism instigated the idea of establishing a new kind of aritocracy, an aritocracy based on talent. Over the years this kind of cultural and social coup has been played out in different ways but has remained, like the twentieth-century concept of the avant-garde, a fundamentally male preserve. He advocated unobtrusive darkblue fitted coats, cream-colored trousers, elaborately tied cravats, absence of showy fabrics or excessive decoration, and impeccable grooming. The status of the perfectly tied cravat as the hallmark of genteel elegance, as the last keystone of Fashion's arch, had been established by Beau Brummell.

  • Yin Yang theory is the first and the last one to interpret diseases apply to treatment in oriental medicine. So it is regarded as the way of heaven and earth, the discipline of all things, the origin of change, the beginning of giving birth and death, the source of spirit. These regulatory passages are needed to compare with western medical physiology and analyzed whether it has scientific bases or not. The Yin Yang theory of traditional oriental medicine are summerized from the descriptions of Scripture of Documents, Ying Wei theory of Huangdi Neijing. Meanwhile up-to-date neurobiological and molecular genetic theories on circadian physiology are reviewed in western medicine. Sunshine is transferred through RGC to SCN, herein the central circadian rhythm is made by zeitgeber and interaction of melatonin secreted from pineal body and orexin from mp pan of hypothalamus. So HPA axis is activated and controlled under the circadian rhythm and affects peripheral tissues and cells of whole body through glucocorticoid hormones. First of all, the circadian rhythm makes the basic patterns of human life in biological and sociological meaning. It is almost same context with the record of the Scripture of Documents. Also the Ying Qi and Wei Qi is basically same with the sleep-awake mechanism, that is melatonin/orexin signal or per/clk/bmal/cry genes with circadian activation and activity of each organ's physiological function. Conclusively it can be said that Yin Yang is a priori principle of living things and the beginning of giving birth and death for activation of them biologically, as is described in Huangdi Neijing.
