Objectives : While cervical cancer is one of the leading cancers among women worldwide, there are a number of effective early detection tests available. However, the participation rates in cervical cancer screening among Korean women remain low. After the nationwide efforts in 1988 and thereafter to encourage participation in cervical cancer screening, few studies have investigated the effects of socioeconomic inequality on participation in cervical cancer screening. The purpose of this study was to investigate 1) the level of socioeconomic disparities in receiving cervical cancer screening by age group and 2) if there was an improvement in reducing these disparities between 1995 and 2001. Methods : Using data from the Korean National Health Status, Health Behavior and Belief Survey in 1995, the Korean National Health and Nutrition Examination Surveys from 1998 and 2001 (sample sizes of 2,297, 3,738, and 3,283), age-standardized participation rates were calculated according to education level, equivalized household income, and job status. Odds ratios and the relative inequality index (RII) were also calculated after controlling for age. Results : Women with lower education levels were less likely to attend the screening test, and the disparities by education level were most pronounced among women aged 60 years and older. The RIIs among women 60 years and older were 3.64, 4.46, and 8.64 in 1995, 1998, and 2001, respectively. Higher rates of participation were reported among those in the highest income category, which was more notable among the middle aged women (40s and 50s). An inconsistent trend in the rate of participation in cervical cancer screening by occupational level was found. Conclusions : Indicators of socioeconomic position seem to have varying impacts on the inequalities in the rates of participation in cervical cancer screening according to age group. These results demonstrate the need for more aggressive and age-based interventions and policy programs to eliminate the remaining inequalities.
As the height and beam span of buildings built in the construction market increase, increasingly higher quality is being required of the construction materials. In response to this trend, 800MPa tensile strength class steel was developed in domestic company. Currently, experiments applying flexural member, compression member, and connections are continuously conducted, but a design guideline for high strength steel has yet to be established. Among those construction materials, for the high strength steel beam-to-column connections, the evaluation of implementing ductile connections for the high strength steel beam-to-column connections is producing pessimistic results and the number of related researches is inadequate because of the high yield ratio, which is the characteristic of high strength steel. This study on implementation of ductile connections made of high strength steel was conducted using the connection detail as the variable, for the purpose of enhancing the deformation capacity of high strength steel beam-to-column connections. Cyclic loading test and nonlinear finite element analysis were conducted with full-scale mock-up connection models with the applied connection details. As a result, the structural performance of high-strength steel beam-to-column connection with presented detail was contented with demand of Special Moment Frames of KBC standard.

An increasing number of cities employ rescaling strategies that not only construct metropolitan production network scaled down from national context, but also tune up new governance to effectively control local geographies of the city. In this context, urban redevelopment has emerged a key 'global' strategy to empower governmental institutions of the city, which not only eliminate such threatening spatial variables as deteriorated housing, working-class ghettos, and crime areas, but also increase and extract exchange value of those spaces. I view such practices a process of 'glurbanization'. This paper investigates how state/city government employs the discourse of urban re/development for 'inventing' poverty at an urban scale: how it institutionalizes the discourse for implementing concrete projects: and how urban institutional apparatus appropriate their discursive practices of redevelopment for their own ends in the city. By particularly focusing on the California Redevelopment Law and the Community Redevelopment Agency of the City of Los Angeles, this paper analyzes the ways in which the law and the agency extract value from what they define 'blight areas' by means of eminent domain and tax increment revenues. For empirical analysis I employ discourse analysis and institutional ethnography. I conclusively argue that the urban spaces stigmatized as 'blight areas' are increasingly entrapped by the urban redevelopment agency, which extracts increased exchange value from the areas and redirects it for supporting external investors, private developers, and the body of the agency itself.
This study is analysis of the existing domestic terrorism factors and suggest countermeasures for political leadership that can occur to the precautionary terror occasion of the presidential election approached 100 days in the future. Political terror caused mainly achieved peak of Ideology or social conflict by Politically alienated class. Common cause is most likely to occur when the party or the government want to attack a target or can not stand disadvantaged and lose that I suppert the party or the government. 21st century political terror is occurred with Misfits of complaints expressed or social conflict more frequency than attack used random people, new weqpon and bomb. It is interpreted that issued as a drastic measure from individual complaint because of increased polarization of wealth by separate into group and fallen law and order but also we are not familiar with the political compromises. Personal safety escort mission is essential condition of political activity that Absolute personal protection and to come up with a large number of voters for best result. Thus security guard ought to professional security activity depend on gathered situation, location and regional feature for perfect protection service.
The purpose of this study is to provide informations for developing next elementary school science textbooks and educational implications for a spot of science class through analyzing patterns of questions in the elementary school science textbooks under the 2007 revised curriculum. To get a meaningful results, the 2,446 questions extracted by operation definition from 3~6 grade science text books were analyzed by modified analysis frame work based on Blosser's classified system. The findings of this study were as follows: First, among 2,446 questions, the propositional pattern element had the highest rate, 49.2%, the appreciable pattern element had the lowest rate, 1.4%, of all pattern elements. Second, from the results of comparing patterns of questions in each grade's science textbook, as the grade went higher, the rate of the applicable and the divergent pattern element tended to increase, and that of the other elements tended to decrease. Third, as the results of comparing patterns of questions of 4 each field in elementary science textbooks, the energy field questions were the largest in number, followed by the substance field. The rate of the propositional pattern element was the highest of all question elements in common in each field. In the reproductive and the propositional pattern element, the energy and the substance field had a little higher rate than the other fields. On the other hand, in the applicable and the divergent pattern element, the earth and the life field had a little higher rate than the other fields.
Complexity metrics have been developed for the structured paradigm of software development are not suitable for use with the object-oriented(OO) paradigm, because they do not support key object-oriented concepts such as inheritance, polymorphism. message passing and encapsulation. There are many researches on OO software metrics such as program complexity or design metrics. But metrics measuring the complexity of classes at the OO analysis phase are needed because they provide earlier feedback to the development project. and earlier feedback means more effective developing and less costly maintenance. In this paper, we propose the new metrics to measure the complexity of analysis classes which draw out in the analysis based on RUP(Rational Unified Process). By the collaboration complexity, is denoted by CC, we mean the maximum number of the collaborations can be achieved with each of the collaborator and determine the potential complexity. And the interface complexity, is denoted by IC, shows the difficulty related to understand the interface of collaborators each other. We verify theoretically the suggested metrics for Weyuker's nine properties. Moreover, we show the computation results for analysis classes of the system which automatically respond to questions of the user using the text mining technique. As a result of the comparison of CC and CBO and WMC suggested by Chidamber and Kemerer, the class that have highly the proposed metric value maintain the high complexity at the design phase too. And the complexity can be represented by CC and IC more than CBO and WMC. We can expect that our metrics may provide us the earlier feedback and hence possible to predict the efforts, costs and time required to remainder processes. As a result, we expect to develop the cost-effective OO software by reviewing the complexity of analysis classes in the first stage of SDLC(Software Development Life Cycle).

In the current study, we proposed an optimized brain-computer interface (BCI) which employed blind source separation (BBS) approach to remove noises. Thus motor imagery (MI) signal and steady state visual evoked potential (SSVEP) signal were easily to be detected due to enhancement in signal-to-noise ratio (SNR). Moreover, a combination between MI and SSVEP which is typically can increase the number of commands being generated in the current BCI. To reduce the computational time as well as to bring the BCI closer to real-world applications, the current system utilizes a single-channel EEG signal. In addition, a convolutional neural network (CNN) was used as the multi-class classification model. We evaluated the performance in term of accuracy between a non-BBS+BCI and BBS+BCI. Results show that the accuracy of the BBS+BCI is achieved $16.15{\pm}5.12%$ higher than that in the non-BBS+BCI by using BBS than non-used on. Overall, the proposed BCI system demonstrate a feasibility to be applied for multi-dimensional control applications with a comparable accuracy.
A study has been made to find out a new method of calculating the survival rate of a fish population from length composition and growth equation. 1. In the steady state of the fish population, let the total mortality rate be z, the age of complete recruitment $\alpha$, and the number of $\chi$ year class $N_\chi$. Then ire obtain $$N\chi=N\alpha\;\exp\;{-z(\chi-\alpha)}$$ Let the oldest age in the catch be h, the average age between the age of complete recruitment and the oldest age in the catch $U\chi$. Then we have $$U\chi=\frac{a-b\;\exp\;(-z(b-a))}{1-\exp\;(-z(b-a))}+\frac{1}{z}....(1)$$ and then let be infinite. Then we obtain $$Z=\frac{1}{U\chi-\alpha....(2)$$ 2. Calculating numerical value of $U\chi$ from age composition table and growth equation and substitute in (1) or (2) for it, we may obtain the value of s and $\varrho^{-z}$. 3. This method is applied t a case of yellow croaker in the Yellow Sea and the East China Sea. The results are as follows: Total mortality rate 0.82595 Survival rate 0.43782 95 percent confidence interval 0.43767-0.43797.
Korean society suffers from severe divisions represented by bi-polarization and collapse of the middle class. Intensive demanding on expanding social welfare budget has emerged in accordance with such a dramatic shift. Social consensus moving toward well-financed welfare policy, however, happens to meet political opposition supported by the discourse of fiscal soundness. This paper thus pays particular attention to deciphering the discursive structure in way of understanding how discourses bring public policy into play. For this purpose, news articles about fiscal soundness collected from 8 national newspapers have been analyzed in terms of frame, attitude, perspective and world view. Research results show, first of all, that there exist persistent competition between two frames identified as 'reduced tax with fiscal discipline' and 'increased tax with welfare money.' While the 'reduced tax' frame favors in maintaining tax cut at the expense of welfare budjet, the frame of 'increased tax' supports such arguments as the flexible employment of fiscal soundness and prosperity of national community helped by widening tax revenues. Also did these frames include a number of sub-frames like welfare populism, partisan politics, trickle down effect, tax bonanza for the rich, universal welfare and market over-reactions in order to bolster its logical authority. Media's active taking a part in penetrating supportive frames in line with political stance was found as well. Taking into account both the discursive structure upheld by frames and politics materialized by the media, the authors argue that public policies should be considered more as discourse than fixed reality. Shedding additional light on understanding the interplay among public opinion, policies and media discourse is of another importance for further study.
The Ministry of Health and Welfare proposed the "undergraduate program specializing in pharmaceutical industry" in 2013, as part of its roadmap to assist domestic pharmaceutical companies to become the top-tier pharma companies in near future and provide skilled personnel tailored for pharmaceutical industry. However, it is not clear whether this "undergraduate program" meets the needs of pharmaceutical industry, especially when the number of pharmacy students increased from 1,200 to 1,700 per year since 2009. The purpose of this paper is to identify which educational background is preferred by pharmaceutical companies, by surveying the CEOs of domestic pharmaceutical companies and referring to recruitment advertisements shown in medical newspapers, specified by the fields within the companies. Two independent reviewers referred to recruitment session in Yakup newspaper and Dailypharm from May 2012 until January 2014, focusing on recruitments from pharmaceutical companies targeting bachelors' degree holders with no prior experience. 749 recruitments were observed during the study period, more than 90% of which were provided by domestic pharmaceutical companies, and regardless of the companies being domestic or multinational, pharmaceutical companies' preference for pharmacists was remarkable (44.3% for domestic and 65.8% for multinational), and the preference was especially high in the fields such as Medical, R&D, Market Access (regulatory affair/pricing and reimbursement), Business Development, and Marketing. Survey results showed that the need of establishing the undergraduate program specializing in pharmaceutical industry is mixed, suggesting that although there is need for the educating personnel targeting pharmaceutical industry, the undergraduate program would not be an answer due to current PEET system. Our study concludes that in the example of pharmaceutical companies' recruitments shown in medical newspapers, pharmaceutical companies prefer pharmacy major in almost all fields of the pharmaceutical companies, yet the pharmaceutical companies still perceive the gap between current bachelor's degree holders(including pharmacy majors) and the ideal personnel required for advancing to the "top-class" pharmaceutical companies.
