This study aims to criticize the recent reform of childcare policy since 2008, which goes for marketization, individualization, and familialization, and to search for its alternative. First, this study analyzes the problems of the above three options based on the context of 'free choice', while examining how welfare regimes have dealt with the changes in childcare policy. Second, the study reviews several controversies in the process of policy formation for childcare service, including coverage of service recipient, policy direction, outcome, efficiency, and priority. Third, it proposes an alternative for accomplishing universal childcare service delivery system. Finally, the paper is to point out that the reform of childcare policy of MB government carries fundamental problems of reinforcing class stratification and gender stratification, and thus dose not attain the ultimate goal of childcare policy.

The British guideline for early management of persistent low back pain, published in 2009, indicated that physicians should offer exercise or medication, rather than radiological interventions or injections, as first choice of treatment in the patients with chronic low back pain (CLBP). However, there had been great controversies regarding the effectiveness of interventional treatment of patients with CLBP. Both somatic (discogenic, instability, etc) and psychosocial factors contribute to the pathophysiology of chronic low back pain (CLBP). Although it can be difficult in many occasions, thorough interview with the patients and specific diagnostic approaches can help us to identify which is the main etiology in individual patient. With the recent progress in medical radiology and development of new therapeutic modalities, some subgroups of patients of CLBP caused by somatic factors appear to be good candidates of interventional therapy. Interventional therapy can be considered in patients with CLBP caused by annulus rupture, facet joint degeneration, disc degeneration, and vertebral column instability. Among other subgroups of CLBP, carefully selected patients with disc degeneration show the most favorable result by interventional therapy. In this regard, discogenic pain, either as a form of CLBP or acute discogenic radiculopathy, seems to be a good indication of interventional therapy. Because many spine specialists generally consider those with radiculopathy are easier to be treated, patients with CLBP tend to be subjects of conventional conservative therapy. For these reasons, clinicians should make their best effort to identify every possible somatic cause in patients with CLBP before regarding them as hypochondriacs. In this review, some of the recent evidence on the role of interventional treatment in patients with CLBP will be discussed, and some of our cases who showed favorable results by interventional therapy will be presented.

Schulz accepted the existentialist view based on Heidegger's thought and at the same time the objectivist view making fixed this living world, evoking controversies for discussion. He could not see various presentations of the meaning of place because he perceived elements of this world individually. Thus Schulz's mixed system of understanding is sternly different from Heidegger's thought. First, Heidegger suggests that place as existential space represents the occasion revelation of incidents in Dasein. While Schulz recognizes that place is a systematic space predetermined for Dasein. Second, Heidegger interprets the placeness as creative openness in which elements comprising this world face and interact with each other into one. In contrast, Schulz defines each of the elements through signification and regards it as invariable and static. Third, Heidegger perceives that the placeness is expressed with sustainable, complex images through "rift-design" which seeks dynamic interactions between the ground and the world. While Schulz attempts to take "Genius Loci" or "habituated scene" through "gathering" as a concept he regards static and then visualize such structural two factors, producing certain internal images of place. However, limits of Schulz's theory prevent us from exerting complete imagination and discovering the inner creative world of the object. Thus the ultimate goal of paying attention to the placeness, that is, the recovery of individual identity, fails due to the prevalence and abstraction of objectified thinking. In contrast, Heidegger's thought about "openness" is a useful means of realizing the placeness. Openness may be referred to a dynamic coordination in which the earth and the world sustain each other under incessant mutual tensions, but not sticking o each other. "Rift-design" is an openness strategy to cause tense relations by preventing structuralization intentively. This is a creative design that allows seeing original seams of the object.

The issue of child care in family policy is one of the most important agendas. It is the primary task for a welfare state to form such conditions as socializing it to ensure labor rights and parental rights. The aim of this study is to review any controversies in the agenda of free choice in child care. But real 'free choice' comes true when all community members as individuals are able to enjoy their rights as both workers and parents without any restriction and sexual discrimination in the labor market. But in reality 'free choice' has not been realized in our society. This study is based on the analysis of these issues in free choice - the concepts of liberty, equity and equality, the role of the state, financial efficiency and the status of women in the labor market. Based on the analysis of the issues in accordance with the criteria, I suggest some policy recommendations: adequate and sufficient child care services, the introduction of univer sal child benefits and the expansion of public child care facilities.

The problem of earthquake induced torsion in buildings is quite old and although it has received a lot of attention in the past several decades, it is still open. This is evident not only from the variability of the pertinent provisions in various modern codes but also from conflicting results debated in the literature. Most of the conducted research on this problem has been based on very simplified, highly idealized models of eccentric one-story systems, with single or double eccentricity and with load bearing elements of the shear beam type, sized only for earthquake action. Initially, elastic models were used but were gradually replaced by inelastic models, since building response under design level earthquakes is expected to be inelastic. Code provisions till today have been based mostly on results from one-story inelastic models or on results from elastic multistory idealizations. In the past decade, however, more accurate multi story inelastic building response has been studied using the well-known and far more accurate plastic hinge model for flexural members. On the basis of such research some interesting conclusions have been drawn, revising older views about the inelastic response of buildings based on one-story simplified model results. The present paper traces these developments and presents new findings that can explain long lasting controversies in this area and at the same time may raise questions about the adequacy of code provisions based on results from questionable models. To organize this review better it was necessary to group the various publications into a number of subtopics and within each subtopic to separate them into smaller groups according to the basic assumptions and/or limitations used. Capacity assessment of irregular buildings and new technologies to control torsional motion have also been included.

Background: There were several studies comparing prognostic factors in Guillain-Barre syndrome treated with intravenous immunoglobulin and plasmapheresis. However, there were controversies in what were significant factors and there were few studies so far comparing the therapeutic outcomes in patients treated with immunoglobulin. This study was aimed to determine the prognostic factors which affected the therapeutic outcome of Guillain-Barre syndrome treated with intravenous immunoglobulin. Method: We retrospectively reviewed the medical records of patients with Guillain-Barre syndrome admitted to our hospital between January 1999 and March 2004. All patients were treated with intravenous immunoglobulin. Outcome and prognosis were followed up after four weeks using the overall disability sum score. Results: Thirty-six patients were enrolled in this study. According to the clinical and electrophysiological findings, 17 patients were AIDP, 10 were axonal forms, two were mixed and seven had electrophysiologically no evidence of abnormalities. At a follow-up of four weeks, disabilities at the nadir (p<0.001) and admission (P<0.012), initial manifestations of bulbar symptom (P<0.024) and electrodiagnostic features (P<0.013) were significantly correlated with outcome in patients treated with intravenous immunoglobulin. But only disabilities at the nadir (P<0.033) and electrodiagnostic features (P<0.018) were significant in the multivariate logistic regression analysis. Conclusion: Among the patient treated with intravenous immunoglobulin, the outcomes were significantly different according to the neurological status at the nadir. Therefore early diagnosis, administration of intravenous immunoglobulin and preventing complications during acute stages are essential to minimize neurological deficit and shorten the periods of recovery.

After SERVQUAL was proposed as a measure of perceived service quality, several arguments have been made against its validity and some competing measures have been developed. This paper reviews those controversies. Particularly, it compares the concept of expectation in the research of service quality with that in the research of satisfaction, re-purchase intention and suggests the authors' opinion. In addition, the paper suggests sequential casual relations among expectation, perceived performance and perceived service quality. With the help of previous researches concerning "SERVQUAL" and the related topics, six variables concerning travel services were identified. The six variables are tangibility, reliability, responsiveness, assurances, empathy and costs. Seven hypotheses were developed using these variables. The review of literature covers service's concept, model and method of service quality evaluation, and relationship among the concepts which is related to the service quality. The results of our study suggest further research is necessary to clarify which one is a better tool because we have a conflicting research outcome in terms of model fitting. The study also shows that assurances and costs have positive effect on customer satisfaction. It also turned out that customer satisfaction has positive effect on repurchase intention.

Background and Objectives: Although laryngopharyngeal reflux disease (LPRD) is a widely recognized disease in the field of otolaryngology, controversies still exist regarding the diagnosis and treatment for it. The purpose of this survey was to find out current trends in diagnosis and management of LPRD among Korean otolaryngologists. Materials and Method: Questionnaires were obtained from 26 Korean otolaryngology specialists by electronic balloting, and 46 members of the Korean Society of Head and Neck Surgery (KSHNS) bye-mail. Survey participants were asked about their preferences in diagnostic policy, duration/dosage of antireflux treatment, and their familiarity to the reflux symptom index (RST) and the reflux finding scores (RFS). Results: The majority of the survey participants (64%) preferred empiric therapy trial with proton pump inhibitors (PPIs) based on patients' symptoms and their laryngeal findings. PPIs alone (27%) or PPIs with prokinetics (32%) were usually prescribed as a first line treatment mostly with once daily schedule in the morning before meal and for less than 4 months of duration (86%). More than 90% of participants were aware of the RSI and RFS, but less than 50% of them were actually using those items in the clinics. Conclusion: Most of Korean otolaryngologists who participated in this survey answered that they prefer starting empirical treatments with proton pump inhibitors mainly based on the patient's symptoms and their laryngeal findings.

Coefficient of determination $R^2$ is most frequently used descriptive measure in practical use of linear regression analysis. But there have been controversies on defining this measure in the cases of linear regression without the intercept, weighted linear regression and robust linear regression. Several authors such as Kvalseth(1985) and Willet and Singer(1988) proposed many variations of $R^2$ to meet the situations. However, theire measures are not satisfactory due to the lack of a universal principle. In this study, we propose a unfied approach to defining the coefficient of determination $R^2$ using the concept of likelihood distance. This new measure is in good accordance with typical $R^2$ in linear regression and, moreover, can be applied to nonlinear regression models and generalized linear models such as logit and log-linear models.

Compound comminuted mandibular fracture is defined as the presence of multiple fracture lines with open wound resulting in many small pieces within the same area. The incidence of mandibular comminution is difficult to determine but reported as 2.7~18.6 % incidence among mandibular fractures. There are controversies in the treatment of mandibular comminuted fractures. Treatment of comminuted mandibular fracture has traditionally involved closed reduction in an effort to avoid stripping periostcum from the bony segments, but rigid internal rigid fixation is used more popular at present. The extent of comminution, displacement of bony fragments and patient general conditions are important factors in decision of the treatment methods. When significant bone displacement is present, it is necessary to reduce these comminuted fragments to an anatomic, pretraumatic relationship to restore facial form and function. In these cases, ORIF allows anantomic reduction of comminuted segments as well as pretraumatic occlusion. Gentle handling of the soft tissue, rigid fixation of bony fragments and adequate immobilization are essential for reducing the complications. This is the report the incidence, causes, complications and treatment of the patients who visited our department for compound comminuted mandibular fractures.
