  • This study analyzed the changes in Electroencephalogram(EEG) and Electrocardiogram(ECG) depending on the healing environment in order to find a way to improve the forest healing program based on the healing environment in response to the demand for qualitative improvement of the program since the program is a charged service. This study selected eight sites running forest healing programs at four national healing forests (i.e., Saneum, Cheongtaesan, Daegwanryeng, and Jangseong) - two routes per national healing forest - considering forest environments. This study chose NUMBER standard sampling plots ($20{\times}20m$) and measured three atmospheric environment items, seven physical environment items, two soil environment items, and eight vegetation environment items including forest sound and anion at each plot to evaluate physiological changes in it. EEG and ECG, which have been widely used in forest healing evaluation, were utilized as criteria. Seventy three subjects were selected with taking the age, drug, caffeine, smoking, and the time of last meal into consideration. As a result, EEG changes were correlated with three atmospheric environment items, six physical environment items, one soil environment item, and two vegetation environment items. ECG changes were significantly correlated with two atmospheric environment items, six physical environment items, two soil environment items, and two vegetation environment items (p<.05). It is expected that 11 environmental factors such as temperature, density, and altitude affecting EEG (e.g., alpha balance and gamma balance) and ECG (e.g., HRV mean) could be used as effective tools in developing more differentiated programs for improving healing effects.

  • The purpose of this study was to identify metacommunicative behaviors between nurses and patients in a pediatric unit. The research method included observation using videotaping. Data were collected from December, 2001 to February, 2002. Total six nurses, and eight patients and their mothers in a pediatric unit participated in this study. The interactions were videotaped under the participants' consent. The participants were observed for total 8 hours over 2-day period. Special episodes which were identified as metacommunicative behaviors in the taped interactions were transcribed. Transcription included verbal and nonverbal interactions. Selected episodes were classified using Mitchell's definition. Each classified definitions were named, and categorized by its purpose. The results were as follows: Nineteen metacommunicative behaviors which used frequently by nurses-approaching, mediating eye level, eye contact, touching, encouraging, turnabout, mimic voice, giving choices, friendly demand, expansion, tagging, repeating and confirming, identification, reflection, baby talk, symbolization, description of acts, relaxed posture, turning away- were identified and organized into four categories. They were call for attention, facilitating response, empathy, and tension release. In conclusion, nurses in this study used metacommunicative behaviors frequently and these behaviors were effective in interacting with children. It is suggested that any educational programs to teach communication skills to nurses need to include techniques on metacommunicative behaviors. This will help nurses to be more sensitive to different characteristics of their patients.

  • This paper contains detailed descriptions of a dynamic time-history modal analysis to calculate deflection, inter-storey drift and storey shear demand in single-storey and multi-storey buildings using an EXCEL spreadsheet. The developed spreadsheets can be used to obtain estimates of the dynamic response parameters with minimum input information, and is therefore ideal for supporting the conceptual design of tall building structures, or any other structures, in the early stages of the design process. No commercial packages, when customised, could compete with spreadsheets in terms of simplicity, portability, versatility and transparency. An innovative method for developing the stiffness matrix for the lateral load resistant elements in medium-rise and high-rise buildings is also introduced. The method involves minimal use of memory space and computational time, and yet allows for variations in the sectional properties of the lateral load resisting elements up the height of the building and the coupling of moment frames with structural walls by diaphragm action. Numerical examples are used throughout the paper to illustrate the development and use of the spreadsheet programs.

  • Health promotion program utilizing traditional korean medicine(TKM) is very unique modality uncommonly conducted throughout the world. Korea's TKM public health services went through initial stage from 2001 and spread throughout the country by 2003. 35 public health centers in the nation is appointed as 'TKM health promotion HUB' and in operation from 2007. But the program is still in the early state and evaluation of usage, satisfaction, and community service is still in demand. This study aims to verify current situations of TKM public health service by examining public awareness, usage, and satisfaction and suggest improvements based on findings. 2.5% of local residents were sampled and 1739 were chosen as subjects. Knowledge, attitude, satisfaction and others for TKM public health service were examined. TKM treatment service was most widely utilized(13.2%), followed by CVA prevention program(5.2%). For satisfaction level, CVA prevention program showed highest satisfaction(73.3%), closely followed by (Qi-gong program 63%). In general, awareness and utilization of TKM public health service were low but compensated by high satisfaction level. More active promotion and development of community specific programs should become available in the future.

  • A study was conducted to investigate the effect of water temperature and photoperiod on the oxygen consumption of the fasting juvenile Pacific cod Gadus macrocephalus (mean body weight 79.9${\pm}$2.0 g) in order to quantify metabolic response of the species under given conditions. The oxygen consumption rate (OCR) of G. macrocephalus was measured under a combination of four different water temperatures (7, 10, 13 and $16^{\circ}C$) and three different photoperiods (24L:0D, 12L:12D and 0L:24D) with an interval of 5 minutes over a 24-hour period using a closed recirculating respirometer. Three replicates were set up in each treatment. OCRs increased with increased water temperatures under all photoperiod conditions (P<0.001). Mean OCRs at 7, 10, 13 and 16oC ranged from 793.7~1108.4, 1145.7~1570.3, 1352.8~1742.5 and 1458.2~1818.6 mg $O_2$ $kg^{-1}$ $h^{-1}$, respectively. Under all water temperature conditions except $7^{\circ}C$ (P<0.001), mean OCRs of G. macrocephalus were the highest in continuous light (24L:0D) followed by 12L:12D and 0L:24D photoperiods. Mean OCRs of fish exposed to the 12L:12D photoperiod were significantly higher during the light phase than during the dark phase under all temperature conditions (P<0.001). $Q_{10}$ values ranged from 3.19~5.13 between 7 and $10^{\circ}C$, 1.41~1.74 between 10 and $13^{\circ}C$ and 1.15~1.35 between 13 and $16^{\circ}C$, respectively. Based on overall results, water temperature, photoperiod and their combinations exerted a significant influence on the metabolic rate of juvenile cod. This study provides empirical data for estimating the amount of oxygen demand and managing the culture of cod under the given water temperatures and photoperiods.
