  • The purpose of this study were to investigate; The contact of housewives with governmental public advertisement about the energy conservation, general tendency about the energy conservation consciousness and behavior. For these purposed, a survey was conducted using questionnaires. Data analysis were conducted from 367 housewives with children in Seoul. Used statistical method were Frequency Distribution, percentile, Mean, one Way Anova, t-test, F-test, Pearson's Correlation, Multiple regression Analysis and Path Analysis. Major findings are as follows. 1) Level of public advertisement contact was low. In contrast to , level of energy conservation consciousness, consciousness change, and behavior was adequately high. 2) Statistically significant difference were found in advertisement contact according to the husband's age , Energy conservation consciousness change according to husband's occupation, and energy conservation behavior according to family life cycle. 3) Energy conservation consciousness changes were increased by advertisement contact. Energy conservation behaviors were increased by conservation consciousness and the degree of conservation consciousness change. 4) Governmental public advertisement about the energy conservation has both direct and indirect effect on the energy conservation behavior. From these finds, the following suggestions are made. Governmental effort about the energy conservation advertisement is needed to be activated.

  • This study presents an analytical method of solving the behaviors of arc plasma in a nozzle constricting transferred-type torch and purposes to obtain the basic data for the design of a plasma torch, which can be obtained from the temperature, pressure, velocities and voltage distributions. We have to solve some conservation equations simultaneously and need to know the exact thermal gas properties in order to obtain the correct behaviors of arc plasma. It is also necessary to give the relevant physical or geometric boundary conditions. For the simplicity of analysis, we assumed that (a) the plasma flow is laminar, (b)the local thermodynamic equilibrium, i.e. LTE, prevails over the entire arc column region. The electrode sheath effects were neglected and the nozzle area was excluded from the analysis by assuming that the current flow into the nozzle is zero. We solved the momentum transfer equation including the self-magnetic pinch effect, and obtained the temperature distribution from the energy conservation equation. From this temperature, we could get arc voltage distribution. (author). refs., figs., tabs.

  • A numerical analysis is conducted to estimate the core expansion and the energy behaviors induced by a core disruptive accident in a sodium-cooled fast reactor. The numerical formulation based on underwater explosion theory is carried out to simulate the core explosion inside the reactor vessel. The transient pressure, temperature and expansion of the core are examined by solving the equation of state and nonlinear governing equation of momentum conservation in one-dimensional spherical coordinates. The energy balance inside the computation domain is examined during the core expansion process. Heat transfer between the core and the sodium coolant, and the bubble rise during the expansion process are briefly investigated.

  • This paper presents the development of 2-dimensional discrete element algorithm to generate circle and line elements for the simulation of the ballast and sleeper in railway. An example of randomly distributed circle elements show a good applicability of this algorithm for the modeling of the behaviors of ballast. The output about unbalaned force, particle velocity, and total energy conservation from the code is evaluated to check if the calculation is conducted properly.

  • Purpose: Cancer-related fatigue is frequently experienced by patients during and after therapy. The present study was conducted to assess the impact of energy conservation strategies and health promotion in breast cancer survivors. Methods: A randomized controlled trial was carried out to compare the intervention effect (n=69.0) with controls (n=66.0) based on routine oncology ward care. The intervention was five weekly sessions for groups of 6-8 breast cancer survivors. Data on fatigue and health promotion lifestyle were obtained before and after completion the intervention and then 8 weeks later for analysis of variance (ANOVA) with repeated measures. Results: Our findings showed cancer-related fatigue to be reduced in the intervention group from pre- to post-intervention, and this persisted over the 8-weeks follow-up period (F = 69.8, p<0.001). All subscales of the cancer fatigue scale demonstrated statistically significant effects with partial eta-squared values ranging from 0.15 (the smallest effect in cognitive fatigue) to 0.21 (the largest for affective fatigue). Changes in the health promotion life style indicated a significant promotion from pre- to post-intervention, and this again continued after 8-weeks follow-up (F = 41.6, p < 0.001). All six domains of a health promoting life style featured significantly elevated values, the largest effect being seen in the interpersonal relations subscale (F=57.7, partial ${\eta}^2=0.21$, p<0.001) followed by physical activity (F=51.9, partial ${\eta}^2=0.18$, p<0.001). Conclusions: The program was effective in decreasing cancer related fatigue and promoting a healthy lifestyle.

  • This study leverages group-based control theory to explore how fresh starts reinvigorate consumers with low motivation to engage in collective environmental efforts. Typically, individuals with low control over their circumstances show less inclination toward collective goals. However, fresh starts can enhance the influence of perceived control on collective environmental engagement, with global identity mediating this relationship. This hypothesis was supported by two empirical studies. The first study analyzed data from 10,430 corporate participants in an energy-saving initiative, revealing that smaller organizations, which likely experience lower levels of control, made substantial energy-saving efforts early in the year, although this effect diminished over time. The second study of 108 college students found that a fresh start mindset and desire for control, mediated by global identity, enhance environmentally responsible behaviors. These findings suggest that fresh starts can effectively connect control perceptions with proactive environmental actions, underscoring their potential to foster collective environmental efforts.
