  • Genomic fingerprinting methods are useful in determining relatedness among bacterial strains. However, random coincidences in sizes of two DNA fragments in two different fingerprints may occur, resulting in erroneous interpretation of relatedness between two bacterial genomes. In this study, I estimated the probability of occurrence of DNA bands of identical size in fingerprints of two unrelated genomes, so that the significance of fingerprint-based estimation of genome relatedness could be analyzed. The probability could be estimated as outputs of a function formulated with the three parameters: the numbers of observed fragments, all possible sizes of fragments and observed fragments common in a given pair of fingerprints. The parameter most instrumental to significance of relatedness estimation was the number of all possible sizes of fragments. To keep the number of coincidentally-common size of fragments below 10, about 200 fragments should be distinguishable in the fingerprints.

  • Beauty Art is an act which makes a face beautiful using various methods such as permanent, manicure and make-up. Recently, Beauty Art is recognized as the personal culture expressing the value of beauty and spirit. Therefore, there are growing interests in the comprehensive study of Beauty Art nor only from the beauty industries but also from academia, because Beauty Art is the high value-added field and Is recognized as a style of the dress. The purpose of this study is to open a new view to understand the Nail Art as a fold of experimental plastic art. The arctic expression is added to Beauty Art to develop it from the routine technique of the make-up and hairstyling to creative art. Assemblage is adopted to provide Beauty Art with fine harmonious expression which develop Nail Art into interesting and unique art area. Assemblage meaning compounding or collection is a technique through which three-dimension is added to two-dimension paintings, and which is an expression of an art work by recollection of miscellaneous articles or waste materials. Assemblage is a term which Jean Dubuffet coioned first in order to differentiate collage used by Picaso or Braque. Here, I present Nail Art Designs which applied Jean Dubuffet's works focusing on Automaticity and Happenstantial phenomena of materials, Materialization, and Directness. These features are characteristics of Assemblage which basic frameworks are fantastic collection, accumulation, constructive collection, and object collection.

  • A 48-years-old woman was visited to our hospital because of incidental finding of intrapulmonary foreign body. Chest X-ray showed a 4cm sized foreign body in left upper lung field without adjacent fibrosis. Chest CT showed a sewing needle shaped foreign body of metallic density, located in the 113ft upper lobe. The foreign bodies including the needle were removed surgically using a wedge resection. The extracted needle was divided into three 4 cm pieces. Patient was discharged without other respiratory symptoms after surgery. We report a case of wedge resection in a patient with intrapulmonary needle in the left upper lobe, with review of literatures.

  • We describe a case of adult tracheoesophageal fisula incidentally found during laparotomy. A 41 year old male came to the emergency room due to multiple injuries from a car accident. An emergent laparotomy was given to the patient to rule out hemoperitoneum, and progressive distension of the stomach was noted with each positive pressure ventilation. The diagnosis of tracheoesophageal fistula was made via an intraoperative esophagogram. Detailed inquiry of the patient's history from his mother together with extensive destructive changes over the right upper lung field on the patient's chest X ray suggested that the fistula was longstanding and not of traumatic origin, obviating the need of urgent operation. The fistula was divided via the right thoracotomy 24 days later. Postoperative course was uneventful.

  • This paper discusses the spike response model of neurons. First, this paper discusses the coding of spikes, the function of spikes, and the construction of the spikes of neurons by the superposition of simple kernel functions. This paper discusses the method of kernel superposition is general than the response of the IF (Integrate-and-Fire) neuron model, too. Next, this paper discusses the coincidence detection and the input weight computation of spiking neurons and the activity of neuron populations in some detail.

  • Purpose: To evaluate the CT features of incidental breast lesions on chest CT and to suggest useful criteria for referral to a specialized breast unit. Materials and Methods: Between May 2009 and April 2014, enhanced chest CT examination reports containing the key word 'breast' were reviewed retrospectively. Patients who had incidental breast lesion and were referred to a specialized breast unit and then underwent pathological confirmation or follow-up over a 1-year period were included. Finally, 86 patients (all female, mean age, $48.9{\pm}12.6years$) were enrolled. Two radiologists evaluated lesion characteristics, including size, shape, margins, and enhancement. The correlations between the CT features and pathologies were evaluated, and the diagnostic accuracy of CT features in various combinations was assessed. Results: Among the CT features, irregular shape, non-circumscribed margin, and high contrast enhancement were different between malignant and benign lesions (p < 0.05). The combination of non-circumscribed margin and high contrast enhancement had the highest accuracy (97.7%). Conclusion: Reliable CT features for incidental malignant breast masses are irregular shape, non-circumscribed margin, and high contrast enhancement. The combination of non-circumscribed margin and high contrast enhancement could help distinguish incidental malignant breast lesions and indicate referral to a specialized breast unit.

  • This paper focuses on the national "flagging" as a current affair, important phenomenon. National flags, it sees, take over varous places, control the surrounding space, and even dictate everybody's perspective by being visualized everywhere anytime. It investigates the issue of national flags and their hoisting poles as a sort of apparatuses that interpellate me as well as us into patriotic 'gookmin'. The placement, arrangement of national flag poles around the country continued throughout 2015 and particularly speeded up in October of the year is regarded as a key symbolic, symptomatic sign to read the transformation of political conjuncture. Preparing a radically conjuncturist cultural study about the changing reality, the researcher will see the flagging poles as a phenomenal result, outcoming of certain intent and plan for reconstructing the political actuality. More precisely, he will interpretate the tall omni-present poles of national flags as a dispositif of appearing the neoliberal/neoconservative capitalist state, as a apparatus of constituting and expressing the masses' psycho-ideological condition of today. The researcher, who perceives the national flag poles as a kind of ISAs. will first review the increased flagging phenomenon and related media discourses. Next, he will critically investigate the 'love our country' 'national flagging' movements organized by the above and operated from the bottom. Then, he will focus more on the very tall national flag poles built and seen around the country. Finally, he will conclude the study with a critical remark, touching briefly the case of controversy over setting a pole in the center of Seoul city square.

  • Purpose: The strudy was done to determine the effect of an exercise program using the muscle strengthening flowchart on flexibility and hand strength and depression of rural elderly women. Methods: For 11 months, from January 9, to November 29, 2013, a survey was done of 37 voluntary participants who were elderly women living in rural areas. This study was a one group pretest-posttest Quasi-experimental research design to identify the effectiveness of self-directed programs. The Korean version of the depression measurement tool (Jo and Kim, 1993) was used. The collected data were analyzed using frequency, descriptive statistics, and paired t-test with SPSS /PC 17.0 program. Results: Comparison of before and after the self-directed program showed that flexibility (p <.001), left grip strength (p <.001), and right grip strength (p <.001) were significantly increased. Depression (p <.001) was significantly reduced. Conclusion: The results of the study show that the exercise program using the muscle strengthening flowchart resulted in of significant muscle strengthening and reduction in depression in rural elderly women. Future use of the muscle strengthening flowchart is recommended to provide long-term operational exercise programs.
