Purpose: This study was to describe and develop public health nursing. Methods: Data were collected from 19 nurses sampled from 5 public health centers. The grounded theory of Strauss and Corbin (1990) was applied. Results: As a result, 48 concepts, 23 subcategories, and 11 categories were deduced from open coding. In axial coding, casual conditions 'facing difficulties of practical administration' and 'attaching importance to health support for residents' and context condition 'assessing of residents' service needs' impacted phenomenon 'searching for efficient performing methods.' Intervening conditions 'forming of support system' and 'working with positive,' and action-interaction conditions 'improving of resident's health and medical accessibility' and 'striving for self-development' lead to consequences 'carried out promptly for field-based problem solving,' 'mastered of successful program planning methods' and 'solving the issues with existing style.' The periods of process were divided into 4 stages, confirming program-contents, probing program-method, developing program-strategies, and applying program-competencies. The core category, ‘strengthening of practical-planning work competencies' incorporated the relationship between and among all categories and explained the process. Conclusion: This study described public health nurses' performance in Korea. These findings have important implications for the practice and must be considered to develop competencies for planning and practice of public health.

Growth in the second-hand clothing (SHC) market has become noteworthy, especially for millennial consumers in Korea. This study identifies the moderating role of fashion leadership influencing the relationship between the perceived environmental benefits of SHC and continuance usage intention for millennial consumers. The hypotheses were statistically tested using online survey data, and the respondents were Korean female millennials aged between 25 and 39 years who had online shopping experiences of SHC within 3 months. Furthermore, 263 responses were analyzed by confirmatory factor, hierarchical regression, and conditional process analyses using SPSS, AMOS, and PROCESS v3.3. Results validated that the perceived environmental benefits of SHC and fashion leadership have positive effects on continuance usage intention of purchased second-hand items. Fashion leadership also moderates the relationship between the environmental benefits of SHC and continuance usage intention, showing that as the level of fashion leadership increases, the environmental benefits have more positive effects on continuance usage intention. Theoretical and practical implications were also discussed. This study will help bridge theoretical and practical gaps between purchasing and using SHC by focusing on the interaction effect of fashion leadership and its perceived environmental benefits.

In this study, sub domain of flow was investigated on literature survey, and suggested of the measuring method of web-site flow and its simulation analysis. Constructing of measuring method of flow, and using this method what-if analysis was simulated when several condition changed. Using causal map approach to extract knowledge from web-site domain experts and to derives a causal relationship of knowledge. Specially, in our study, describes method of developing and building causal map, and suggests guide line of this method on practical application. This research results show that web-site flow starts "direct searching" or "interesting of special issue(domain)", and when challenges of web-site were accorded with user's skills web-site flow grows. Further, in the web-site, information searching intention results in increase of user's duration time and experience flow to discovery new interesting issues in this process. If user's web-site of interaction is increased, awareness of environment conditions decreased, finally, user's telepresense results in increased web-site flow. This paper contained thai this method make used of measuring flow in the web-site and developing of practical strategy.

Study of turbulent mixing layers has been a popular subject from the point of view of both practical application and phenomenological importance in engineering field. Turbulent mixing layers can be applied in many fields where rapid transition to turbulence is desirable in order to prevent boundary layer separation or to enhance mixing. The ability to control mixing, structure and growth of the shear flow would obviously have a considerable impact on many engineering applications. In addition to practical applications, free shear flows are one of the simplest flows to understand the fundamental mechanism in the transition process to turbulence. After the discovery of large-scale vortical structure in free shear flows many researchers have investigated the physical mechanism of generation and dissipation processes of the vortical structure. This study investigated the role of the large-scale vortical structures in the turbulent mixing layer using LES(Large-Eddy Simulation). The result shows that the pairing interaction of the vortical structure plays an important role in the growth rate of a mixing layer. It is found that the turbulence quantities depend strongly on the velocity ratio. It is also found that the vorticity in the high-velocity-side can extract energy from the mean flow, while the vorticity in the low-velocity-side lose energy by the viscous dissipation. Finally the results suggest the guideline to obtain the desired flow by control of the velocity ratio.

Concrete filled steel tube column has a large load carrying capacity through its steel and concrete interaction which makes it useful in construction. However, it has not been used often in a practical construction field. This is partly due to the non-destructive inspection method for concrete filling which has yet to be established. Furthermore, there are the lack of test data and a practical method in evaluating the ultimate load carrying capacity of concrete filled steel tube column. This paper will attempt to predict the ultimate strength of short concrete filled square tubular steel columns through conducting several tests. To accumulate the new test data on concrete filled steel tube columns, a total of 42 specimens of steel tubular columns were monotonically tested under concentric axial force, having the slenderness ratio(${\lambda}=10,\;15,\;20$), width-thickness ratio(d/t=25.0, 33.3) and concrete strengths($F_{c}=210,\;240,\;270kg/cm^{2}$). The hollow sections and concrete filled steel columns were compared to check the lateral confinded effects by steel tube. Through these test results, we propose a coefficient k=3.64 for the strength evaluation formula(10) of concrte filled tubular steel short columns.

Objectives: Modafinil is a waking drug prescribed to narcolepsy patients, but its usage among healthy individuals is increasing to enhance their alertness or to mitigate fatigue. This study was conducted to investigate practical use and toxic effects on neuro-immune interaction of modafinil. Methods: This study reviewed the significance of psychoactive drugs, and discussed the benefits and risks of the application of modafinil, which seems to be ideal as an anti-psychotic or anti-fatigue agent. Results: Modafinil is known to have less or no adverse effects than those found in traditional psychostimulants such as amphetamine, methylphenidate or cocaine. It can be applied as an anti-psychotic or anti-fatigue agent. However, the waking mechanism of modafinil is yet to be fully revealed. Recent studies reported that modafinil may be subject to abuse and addiction. In addition prolonged sleeplessness induces stress responses and impairs immune function. Conclusions: Modafinil can be used by anyone, who wishes to work late, stay awake, enhance their cognitive reactions, or brighten their moods. Users may already be under a great level of stress, i.e. cancer patients or soldiers in a battle field. A psychoneuroimmunological approach is thus needed to investigate the multi-functional effects of modafinil.
