The Practice of Landscape Urbanism has been criticized on two aspects; Landscape Urbanism does not yet provide differentiated forms of planning and design neither able to fill the gap between theory and practice. In response to these criticisms, Landscape Urbanists have tried to provide additional cases that can exemplify achievements of Landscape Urbanism in practice. There has been another type of effort to suggest distinct planning and design strategies of Landscape Urbanism from theoretical texts. However, these approaches overlooked the fact that professional practice actually gave huge influence on the theoretical framework of Landscape Urbanism. Based on this observation, the study examined the development process of Landscape Urbanism by verifying the correlation between its practice and theory. Through an extensive literature review, the study suggested horizontality, infrastructure, process, ecology, media, hybrid, site, and scale as eight major concepts of Landscape Urbanism. Afterwards, the study classified 51 projects cited in major essays and articles of Landscape Urbanism into four categories: Archetypal projects, precedent projects, exemplary projects, and progressive projects. The correlation between strategies of the selected projects and main theoretical concepts was analyzed. The study found out that the early stage of the theory was focused on defining and explaining the new design and planning approaches of contemporary design projects related with landscape. However, these days, Landscape Urbanism became a more productive in providing diverse types of practice sharing the direction and vision proposed by the theory. Various projects influenced in constructing theoretical structure of Landscape Urbanism as well as proved that the suggestions of Landscape Urbanism could be effective to reorganize contemporary cites in the form of design and planning strategies. The observation of this study can contribute to provide proper answers to the criticism on practice of Landscape Urbanism and be helpful in understanding the limits and unrealized potentials of Landscape Urbanism as a practical theory.

Objective: This study was performed to identify associations between the practice of health behaviors and awareness of metabolic syndrome (MetS) among adults aged 19 to 64 years in the Gwangju-Jeonnam area. Methods: This study utilized data from the 2010 Community Health Survey (CHS). Health behaviors considered in this study were smoking, alcohol drinking, physical activity, low-salt diet, and perception of stress. The index for the health behaviors was calculated as the sum of the practice of each health behavior (range: 0-5). The analysis was weighted with a complex sampling design, and the chi-square test and multiple logistic regression analysis were used to identify the association between the practice of health behaviors and awareness of MetS. Results: A total of 19.8% of the population were aware of MetS. The perception of MetS was statistically significantly associated with healthy behaviors, including nonsmoking (aOR = 1.33, 95% CI = 1.14-1.56), non-high-risk drinking (aOR = 1.54, 95% CI = 1.27-1.88), engagement in physical activity (aOR = 1.48, 95% CI = 1.28-1.72), and a low-salt diet (aOR = 1.30, 95% CI = 1.13-1.51). The ORs of the perception of MetS were significantly higher in patients with a health behavior index of 2 to 3 (aOR = 1.64, 95% CI = 1.01-2.66) and in those with an index of ${\geq}4$ (aOR = 2.47, 95% CI = 1.51-4.04) than in those with an index of 0. Among all health behaviors, physical activity had the highest OR for the perception of MetS (aOR = 1.50, 95% CI = 1.29-1.74). Conclusions: This study revealed associations between health behaviors, especially physical activity, and awareness of MetS. Therefore, integrated health promotion programs may be needed to enhance awareness of MetS and to effectively prevent MetS and non-communicable diseases.

Most of every teachers' life is occupied with his or her instruction, and a classroom is a laboratory for mutual development between teacher and students also. Namely, a teacher's professionalism can be enhanced by circulations of continual reflection, experiment, verification in the laboratory. Professional development is pursued primarily through teachers' reflective practices, especially instruction practices which is grounded on $Sch\ddot{o}n's$ epistemology of practices. And a thorough penetration about situations or realities and an exact understanding about students that are now being faced are foundations of reflective practices. In this study, at first, we explored the implications of earlier studies for discussing a teacher's practice. We could found two essential consequences through reviewing existing studies about classroom and instructions. One is a calling upon transition of perspectives about instruction, and the other is a suggestion of necessity of a teachers' reflective practices. Subsequently, we will talking about an instance of a middle school mathematics teacher's practices. We observed her instructions for a year. She has created her own practical knowledges through circulation of reflection and practices over the years. In her classroom, there were three mutual interaction structures included in a rich expressive environments. The first one is students' thinking and justifying in their seats. The second is a student's explaining at his or her feet. The last is a student's coming out to solve and explain problem. The main substances of her practical know ledges are creating of interaction structures and facilitating students' spontaneous changes. And the endeavor and experiment for diagnosing trouble and finding alternative when she came across an obstacles are also main elements of her practical knowledges Now, we can interpret her process of creating practical knowledge as a process of self-directed professional development when the fact that reflection and practices are the kernel of a teacher's professional development is taken into account.

This study analyzed activities in chemistry chapters of middle school science textbooks for the 2009 revised curriculum using 8 science practices. All the activities that students could experience inquiry were analyzed in this study. There were the most activities in 'Molecular motion and change of state' and the least activities in 'Heat and our life' of three textbooks. There were the most science practices in 'Features of substance' in two textbooks, but there were the least science practice in 'Heat and our life' of three textbooks. 'Investigation planning and performing', 'data analyzing and interpreting', and 'explanation composition and problem solution designing' were frequently included, but 'asking questions and defining issues' was not included at all. For 'Investigation planning and performing', 'data analyzing and interpreting', and 'explanation composition and problem solution designing', a variety of achievement goals were targeted while a few goals were frequently targeted. Two to four kinds of science practices were frequently included in an inquiry activity. There were few activity that includes over 5 different kinds of science practice.

This study aims to explore science inquiry teaching efficacy that middle school science teachers implementing science practice-based teaching for one year recognized as necessary for teaching science through science practice. Examining interview data in this study, science inquiry teaching efficacy was identified in both planning and implementing in the areas of managing efficacy, instructional strategy efficacy, and content knowledge efficacy. In planning science inquiry instruction, there is science curriculum management efficacy under managing efficacy. There are the efficacy of outlining science inquiry lesson, efficacy of organizing science practice, efficacy of questioning for science practice, and efficacy of understanding student science practice under instructional strategy efficacy. Under the content knowledge efficacy are contents and science practice understanding efficacy and core ideas efficacy. In implementing science inquiry instruction, managing efficacy includes science practice time management efficacy and science practice classroom culture efficacy. Instructional strategy efficacy includes efficacy of motivating student science practice, efficacy of responding to student science practice, efficacy of stimulating student active thinking, efficacy of student active engagement in argumentation, efficacy of evaluating student participation. No content knowledge efficacy have been identified in implementing science inquiry instruction.

This study aimed to assess the prevalence of weight control behaviors and their association with food and nutrient intake among Korean adults. Study subjects were 7,340 Koreans aged 20 years and older in the 1998 Korean Health and Nutrient Survey. Cross-sectional data were collected on weight control behavior and diet using structured questionnaire by interview. Analysis of variance following after Duncan's multiple range test was used to test the differences in food and nutrient intake among three different weight control behavior groups(weight reducing attempt, weight gaining attempt, none). Current weight control behaviors were reported by 32% of the study subjects. There were significant differences in weight control behaviors between male and female subjects; weight reducing practices were 7 times greater than weight gaining practices among female subjects while it was only 1.5 times among male subjects. Weight control behaviors were not consistently associated with food and nutrient intake among male and female subjects. Moreover, greater food and nutrient intake were observed among those who trying to reducing weight than those who did not try. Therefore, it Is necessary to educate the Korean adults that balanced food and nutrient intake with sustaind weight control effort is the ideal way to achieve healthy weight.

The current status of Korean social work can be summarized as multiple complexities and ambiguities not only in ideological but in practical aspects. Although they have long been considered as an unique feature of social work as one of representative human service professions, the extent of such complexities are now reaching the culmination enough to raise the questions about the very nature of social work practice. This study aims to analyse such ambiguities and complexities around the field of social work in a systematic ways with the theory of liquid modernization, an creative framework for modern society, coined by Zygmunt Bauman who is now considered as one of the leading sociologist and thinker. The study shows clearly that social work in Korea is nowadays entering the phase of liquid modern society and specific features of liquidity of modern society such as consumerism, privatization, corruption of publicity etc are founded in the areas of social work. To make it worse, social work are thinking about the anachronical response to this flow of liquidity by selecting the strategies useful in solid modern era, not in the liquid one. In this context, the study suggests that social work practice have to prepare to adequate measures to secure its own autonomy and sustain genuine identification from the ruthless melting power of liquid modern society.

This study was conducted to identify the relationship between knowledge, attitude, and compliance regarding infection preventive behaviors among long-term care hospital staff during a Middle East Respiratory Syndrome (MERS) epidemic. The subjects were 211 staff members of a long-term care hospital in J province evaluated using a structured survey. Data were collected between June 15 and July 15, 2015 and analyzed using SPSS/WIN 24.0 based on an independent t-test, ANOVA, and Welch test, while post-hoc tests were conducted using the Scheffe test and the Grames-Hawell test. The MERS knowledge score of the staff at the long-term care hospital was high for nurses and nurse aids, who had experienced infection management when they received influenza vaccine in the previous year and were provided with easy access to hand sanitizers. Attitude towards MERS was more positive for nurses than nurse aids and caregivers. The degree of execution of infection preventive behaviors in terms of daily activity was high when influenza shots were received in the prior year; in terms of caring for patients, it was high when influenza shots were received in the previous year and they had easy access to hand sanitizers. The relationship between knowledge, attitude, and infection preventive behavior regarding MERS was such that high knowledge and positive attitude led to a higher degree of execution of infection preventive behavior. Therefore, during periods of high prevalence of newly infectious diseases such as MERS, it is important for the long-term care hospitals to conduct infection management education including the characteristics of the MERS disease, its transmission, and its prevention to enhance knowledge regarding MERS and induce positive change in attitude to improve the level of infection preventive behaviors.
