Purpose: This study was done to evaluate factors affecting active early detection behaviors of breast cancer and performance rate of breast self examination (BSE), physical examination and mammography. Methods: The participants were 264 women from an outpatient breast clinic of a university hospital and materials were collected from March 2007 to February 2008 using a structured questionnaire. The data were analyzed using $x^2$ test, logistic analysis. Results: The rate for BSE was 58.3%, for physical examination, 55.3% and for mammography experience, 63.4%. Women with all of these active early detection behaviors accounted for 31.8% of the participants. Various factors such as age, income, marital status, and menopause showed increased significant performance rate. The explanation power of logistic model was 48.5%, and was significant for age, income and health belief. Factors related to high performance rate were being over 40 years of age, high income and high health belief score. Conclusion: Active early detection behaviors were not high in spite of marked increases in breast cancer incidence. Encouragement for women practicing early detection behavior is important, but there is also a need to develop interest and support for the low performance group. More sustained education and public relations are needed to further improve active early detection behavior.

Objectives: The purpose of this study was to explore the effects of injection laryngoplasty (IL) with hyaluronic acid in patients with vocal fold paralysis (VFP). Methods: A total of 50 patients with VFP participated in this study. Pre- and post-IL assessments were performed, which included analyzing the sustained vowel /a/ phonation, and the patient reading 1 Korean sentence from the "Walk" passage that comprised 25 syllables in 10 words. To investigate the effect of IL on vocal fold function, acoustic analysis (acoustic voice quality index, cepstral peak prominence, maximum phonation time, speaking fundamental frequency) was conducted and auditory-perceptual (grade and overall severity), visual judgment (gap), and self-questionnaire (voice handicap index-10) assessments were performed. Results: The patients with VFP showed statistically significant differences between pre-and post-IL assessments for acoustic and auditory-perception, visual judgment, and self-questionnaire assessments. Conclusion: The patients with VFP showed positive change in vocal fold function between pre- and post-IL measurements. The findings showed that IL with hyaluronic acid is an effective method to improve vocal fold function in patients with VFP.

The aim of this essay was to investigate Marlow's desire for constructing enlightenment subject of knowledge and power sustained by the collusion of imperialism and patriarchy in Joseph Conrad's Heart of Darkness. Marlow's narrative, based on his journey up the river in Africa to retrieve Kurtz, attempts to conceptualize himself as the subject of the enlightenment reason and rationality. In the novella, collusive network of ideologies of empire and gender contributes to the making of a Western Enlightenment subject. Marlow eulogizes himself for realizing the harsh realities of imperialism, political domination and economic exploitation of the natives in Africa. However, Marlow is a colonial subject who has been ruled by the hierarchical system of thought in the Western logocentrism. He is not aware that his narrative has already been infiltrated by the ideological discourse of the totalitarian enlightenment. His narrative in effect is not a self-congratulatory testimony to truth and realities but a narcissistic and self-defeating document. Marlow unconsciously employs the totalitarian ideologies of empire and gender in order to relegate the African natives to the inhuman existence and to consign women to the sphere of illusion.

Transportation plays a vital role in sustainable development, and moreover, bulk transportation provides cost effective movement of goods and human beings with less environmental issues. Nepal is a developing country with increasing urbanization and transportation demands. The growing interest of China to connect with Southeast Asia through Nepal has led to ambitious project proposal of Rasuwa Gadhi to Birgunj Railways, which is the shortest route from China to India. Lack of updated geospatial data has lead the concerned authorities in Nepal to be dependent on analysis and proposals from donor nations. Taking such considerations, based on GIS and free data, this study explores optimal routes to connect cites using slope and land cover. Based on reclassified slope, two shortest optimal routes were found. One passing through Baireni in Dhading and another through Kathmandu towards Birgunj with length of around 172 Kilometers. The study shows that available open source data can be used of preliminary feasibility studies and yet shows limitations for detailed economy based planning. Development and use of high resolution updated geospatial data is of high necessity for Nepal to become self-sustained in planning of development works.

A 'circadian rhythm' is a self-sustained biological rhythm (cycle) that repeats itself approximately every 24 hours. Circadian rhythms are generated by an internal clock, or pacemaker, and persist even in the absence of environmental time cues, collectively termed 'zeitgebers.' Although organisms generate circadian rhythms internally, they are entrained by environmental stimuli, particularly the light-dark cycle. Measurement of the endogenous melatonin rhythm provides relatively reliable surrogate way of assessing the timing of the internal circadian clock. Also, core body temperature and cortisol can be used as markers of circadian rhythms. The sleep-wake cycle, body temperature, and melatonin rhythm have a stable internal phase relationship in humans and other diurnal species. They play an important role in controlling daily behavioral rhythms including task performance, blood pressure, and synthesis and secretion of several hormones. In this review, we address not only the properties, methods of measurement, and markers of circadian rhythms, but also the physiological and psychological importance of human circadian rhythms.

Transformations of the urban spatial structure, from sub-area redevelopment to newtown development, results great influences upon existing urban condition and spatial configuration. The purpose of the study is to analyse the effect of the urban spatial configuration of Uijongbu city where experienced changes after newly development of city center and new residential area. The west part of the city where is limited in growth by military bases, ego U.S Army basecamp, were planned and established as the other axis of the city center since mid 1980's. After that new residential area which is located in far east of the city were also developed. Space syntax as a methodology has been adopted to conduct quantitative analysis which is able to interpret differences between sub-areas ; old city center, new city center, new residential area. The results of the analysis are follows ; 1) existing structure of the urban fabric, especially old city center, is sustained and intensified, 2) new city center which is west part of the city has failed to achieve organic spatial connection adjacent to old city center, 3) there is less spatial depecdency relationship between city center and new residential area where is identified as another small self-support city within the city.

The purposes of this study were to identify patients' perceptions toward regulations of smoking in general hospitals and hazards caused by smoking. Moreover this study also identified smoking behaviors and punishment experience due to in-hospital smoking and education experiences of smoking in general hospitals. Around 88.0％ of all respondents regardless of either smokers or non-smokers knew that hospitals are non-smoking area. However, 71.6％ of smokers smoked during their hospital visits. For their smoking, only 51.0％ of smokers utilized smoking rooms or areas for their smoking. Only 55.1％ of smokers experienced punishments or notifications of warning due to their smoking. Around 93.0％ of inpatients and outpatients acknowledged hazards toward their health caused by smoking. However, smokers did not realize the dangerous effects of passive smoking to other persons. Only 38.1％ of smokers said that passive smoking causes hazard of others' health. 63.8％ of smokers hoped for secession of smoking but only 42.8％ of them sustained their non-smoking periods over 5 moths. Based on these results, this study insists that a more enforced smoking policy in general hospitals be desperately needed for protecting patients' health and controlling smoking at unapproved areas. Moreover hospitals should take proactive actions to prevent smoking in hospitals. A health education program in hospitals should promote patients' self-efficacy to stop smoking and patients' understanding of the hazardous effects of passive smoking in hospitals.

The unsteady supersonic flow over two- and three-Dimensional cavities has been analyzed by the integration of unsteady Reynolds-Averaged Navier-Stokes(RANS) with the k - w turbulence model. The unsteady flow is characterized by the periodicity due to the mutual relation between the shear layer and the internal flow in cavities. Numerical method is upwind TVD scheme based on the flux vector split with the Van Leer limiters, and time accuracy is used explicit 4th stage Runge-Kutta scheme. Cavity flows are Comparison of two- and three-dimensional. The cavity has a L/D ratio of 3 for two-dimensional case. and same L/D and W/D ratio is 1 for three-dimensional case. The Mach and Reynolds numbers are held constant at 1.5 and 450000 respectively. For the three-dimensional case, the flow field is observed to oscillate in the 'shear layer mode' with a feedback mechanism that follow Rossiter's formula. On the other hand, the self-sustained oscillating flow transitions to a 'wake mode' for the two-dimensional simulation, with more violent fluctuations inside the cavity.

The unsteady supersonic flow over two- and three-dimensional cavities has been analyzed by the integration of unsteady Reynolds-Averaged Navier-Stokes(RANS) with the k-$\omega$ turbulence model. The unsteady flow is characterized by the periodicity due to the mutual relation between the shear layer and the internal flow in the cavity. An explicit 4th order Runge-Kutta scheme and an upwind TVD scheme based on the flux vector split with the van Leer limiters are used for time and space discritizations, respectively. The cavity has a L/D ratio of 3 for two-dimensional case, and same L/D and W/D ratio of I for three-dimensional case. The Mach and Reynolds numbers are 1.5 and 450000 respectively. In the three-dimensional flow, the field is observed to oscillate in the 'shear layer mode' with a feedback mechanism that follows Rossiter's formula. In the two-dimensional simulation, the self-sustained oscillating flow has more violent fluctuation inside the cavity. The primary fluctuating frequencies of two- and three- dimensional flow agree very well with the 2nd mode of Rossiter's frequency. In the three-dimensional flow, the 1st mode of frequency could be seen.

Kikuchi disease(subacute necrotizing lymphadenitis), first reported by Kikuchi and Fujimoto in 1972, is a benign self-limiting illness characterized by fever, neutropenia and cervical lymphadenopathy and develops predominantly in young women, especially in Asia. The cause of Kikuchi disease is unknown, but postinfectious(virus or bacteria) hyperimmune reaction has been suggested. Few pediatric cases have been reported. We experienced a case of Kikuchi disease associated with Yersinia pseudotuberculosis infection in 12-year-old girl. After she was admitted with cervical lymphadenopathy and headache, followed by sustained fever with leukopenia. All symptoms and signs did not seem to be responded to antimicobial treatment. Open biopsy of cervical lymph node was performed and showed findings consistent with subacute necrotizing lymphadenitis. Serologic studies were all negative except for Y. pseudotuberculosis. Fever subsided and lymphadenopathy improved after administration of oral steroid for 1 week.
