Purpose: The purpose of this study was to explore the relationships among pain, depression, health behaviors, and activities of daily living (ADL) in older adults after femur fracture surgery. Methods: This was a descriptive correlational study. Ninety seven outpatients aged 65 or older were selected, who agreed to participate and visited the four hospitals located in G providence. Numeric Rating Scale (NRS) for pain, a Short form Geriatric Depression Scale (SGDS) for depression, health behavior scale and Korean version of Bathel Index for ADL were used. Data were analyzed using t-test and ANOVA, Pearson's correlation and the hierarchical regression analysis in SPSS 18. Results: Pain and depression were positively correlated (r=.35, p<.001). Pain and health behaviors (r=-.30, p=.010), pain and ADL (r=-.21, p=.044), depression and health behaviors (r=-.51, p<.001), depression and ADL (r=-.29, p=.004) were negatively correlated. The variables affecting the ADL was intake of a painkiller or not (${\beta}$=-.32), age (${\beta}$=-.25), transitional period after discharge (${\beta}$=.23) and depression (${\beta}$=-.23). ADL was accounted for 33.4% in total by these four variables. Conclusion: Interventions for alleviating pain, and managing depression would be effective in enhancing ADL in older adults after femur fracture surgery.

The effect of an aluminum scrap addition ratio on the tensile and solidification cracking properties of the AC4A aluminum alloy in the as-cast state and heat-treated state were investigated in this study. Generally, the expected problem of using scrap in aluminum casting is an increase of hydrogen and Fe element inside the aluminum melt. Another issue is an oxide film which has a weak interface with the molten aluminum and acts as potent nucleation sites for internal porosity and crack initiation. Solidification cracking is one of the critical defects that must be resolved to produce high quality castings. A conventional evaluation method for solidification cracking is a relative and qualitative analysis method which does not provide quantitative data on the thermal stress in the solidification process. Therefore, a newly designed solidification cracking test apparatus was used in this study, and the device can provide quantitative data. As a result, after conducting experiments with different scrap addition ratios (0%, 20%, 35%, 50%), the tensile strengths and elongations in the as-cast state were 214, 187.7, 182.1 and 170.4MPa and 4.6%, 3.4%, 3.1% and 2.3%, respectively. In the case of the T6 heat-treated state, the tensile strengths and elongations were 314.9, 294.6, 293.1 and 271.1MPa and 5.4%, 4.6%, 3.8% and 3.1%, respectively. The strength of the solidification cracking was 3.1, 2.4, 2.2and 1.6MPa as the scrap addition ratio increases.

The Antarctic Peninsula is important in terms of global warming research due to pronounced increase of air temperature over the last century. The first eddy covariance system was established at King Sejong Station located in the northern region of the Antarctic Peninsula in December of 2002 and has been operated over one year. Here, we analyze turbulent characteristics to determine quality control criteria for turbulent sensible heat flux data as well as to diagnose the possibility of long term eddy covariance measurement under extreme weather conditions of the Antarctic Peninsula. We also report the preliminary result on sensible heat flux. Based on the analyses on turbulent characteristics such as integral turbulence characteristics of vertical velocity (w) and heat (T), stationarity test and investigation of correlation coefficient, they fallow the Monin-Obukhov similarity and eddy covariance flux data were reliable. ${\sim}47%$ of total retrieved sensible heat flux data could be used for further analysis. Daytime averaged sensible heat flux showed a pronounced seasonal variation, with a maximum of up to $300Wm^{-2}$ in summer. In conclusion, continuous and long-term eddy covariance measurement may be possible at the study site and the land surface may influence the atmosphere significantly through heat transport in summer.

Objective : This study aimed qualitative change of traditional korean medical public health programs (TKM-PHP) by the research of present condition, problems and improvement direction about TKM-PHP. Methods : Data were collected from 222 of 996 public health oriental medical doctors(PHOMD) using the structured questionnaire by e-mail. Collected data were analyzed through frequency analysis, T-test, and ANOVA using SPSS 12.0 and significant level was 0.05. Results : 59.5% of the respondents said that the TKM-PHP are not efficiently executed because there are not enough motivations to entice oriental medical doctors in charge of the programs and because PHOMD and the government officials in charge lack in relevant experiences and skills. A majority of the PHOMD recognize a need for activating the TKM-PHP but less actively participate in the programs since there is not a good rewarding system and there are neither standard manuals nor methodological guidelines for the programs. In order to activate the TKM-PHP, it is urgent to employ full-time oriental medical doctors and to continually and systematically appoint the professional manpower in charge. And it is also needed for the state to secure an adequate budget and prepare schemes for persistently train such professionals. Conclusion : Activating the TKM-PHP will lead to the development of TKM, but there are still such problems as lack of the professional manpower in charge, an excessive burden of the duties of PHOMD, lack of program manuals, and a poor system for evaluation. To solve these problems, it is advised to construct foundations for administerial supports, draw up a standard manual, prepare a system for evaluation in consideration of the characteristics of TKM, and hire professionals to ensure sustainable programs.

Purpose: To determine the effects of 630 nm light emitting diode (LED) on full-thickness wound healing. Methods: Twelve male Sprague-Dawley rats were randomly divided into LED (n=6) and control group (n=6). Two $19.63mm^2$ wounds were created on the mid dorsum. LED group received a 630 nm LED irradiation with $3.67mW/cm^2$ for 30 minutes ($6.60J/cm^2$) for 7 days, while control group received sham LED irradiation. Epithelial gap, collagen density, ${\alpha}$-SMA fibroblast and PCNA keratinocyte were measured on histochemical and immunohistochemical staining using image analysis system. An independent t-test was conducted to compare the difference between groups. Results: The wound closure rate, collagen density, ${\alpha}$-SMA fibroblast number, epithelial gap and PCNA keratinocyte number have shown no significant difference between LED and control group at day 3 after the treatment. At day 7 after the treatment, the wound closure rate in LED group was increased when compared with control group (p<0.05). The collagen density (p<0.05) and ${\alpha}$-SMA immunoreactive fibroblast number (p<0.001) were increased when compared with control group at day 7. The epithelial gap in LED group was significantly shorten than control group at day 7 (p<0.01). The PCNA positive cell number in LED group was higher than control group at day 7 (p<0.01). Conclusion: 630 nm LED with $3.67mW/cm^2$, $6.60J/cm^2$ accelerate collagen deposition by stimulating fibroblasts, and enhance wound contraction by differentiating myofibroblasts in the dermis, and accelerate keratinocyte proliferation by facilitating DNA synthesis in the epidermis. It may promote the healing process in proliferation stage of wound healing.

Purpose: The aim of this study was to determine the effect of proprioceptive neuromuscular facilitation (PNF) leg patterns on muscle activation of paretic and nonparetic arm in post-stroke hemiparetic subjects. Methods: Eighteen hemiparetic patients participated in this study. Each subject was asked to perform four PNF leg patterns against maximal manual resistance on nonparetic leg. EMG data were collected from biceps and triceps on the paretic and nonparetic side. The measured EMG data was digitized and processed to root mean square (RMS) and expressed as percentage maximal voluntary isometric contraction (％MVIC). The data were analyzed using paired t-test and one-way analysis of variance (ANOVA) with repeated measures to determine the statistical significance. Results: The results of this study were summarized as follows: Firstly, during four PNF patterns application, all of the ％MVIC values of biceps and triceps in paretic and nonparetic arms increased significantly compared with resting condition (p<0.05). Secondly, there was a significant difference in ％MVIC of paretic biceps between PNF leg pattern 1 and 4 (p<0.05). Conclusion: In conclusion, regardless of the kinematic components of PNF leg patterns, all of the muscle activation of biceps and triceps in paretic and nonparetic arm was significantly increased. The finding of this study indicates that irradiation effect caused by PNF leg patterns is beneficial for increased muscle activation of both paretic and nonparetic arms in post-stroke patients.
