This study was performed to investigate the effect of kangaroo care on body weight, physiological responses and behavioral states in premature infants. The subjects were 32 premature infants, fifteen for the kangaroo care group and seventeen for the control group, who hospitalized in a neonatal intensive care unit at a university-affiliated hospital. The kangaroo care was applied 8 times during the twenty five days with 40 minutes for each session. The kangaroo care provides the skin-to-skin contact during which a premature infant wearing a diaper and a hat is placed on its mother's chest. As for the measures, body weight was measured everyday. The levels of epinephrine, norepinephrine and 17-OHCS were measured twice, before beginning the first intervention and after finishing the last intervention. While each session of the care is undergoing, such physiological responses were measured periodically as heart rate, respiration rate, oxygen saturation, core temperature and skin temperature. The results were as follows : 1. The weight gain was significantly greater in the kangaroo care group than that in the control group during the period of performing the kangaroo care. 2. No significant difference was revealed between the two groups in heart rate, respiration rate, oxygen saturation and core temperature. The kangaroo care group also showed significant increases in the skin temperature. 3. The differences in the levels of epinephrine, norepinephrine and 17-OHCS were not significant between the kangaroo care and the control groups. The level of norepinephrine in the two groups was significantly increased over time. 4. Sleep pattern changed significantly in the kangaroo group from a very restless sleep to a very quiet sleep. These results suggest that kangaroo care is an effective nursing intervention for premature infants in gaining weight, achieving stable physiological responses and facilitating a quiet sleep.

In this study, the stability of cream containing 1% of cannabidiol (CBD) with more than 99% extracted from domestic Cannabis sativa was evaluated. The pH, hardness, content, and chromaticity were measured at intervals of 2 weeks under storage conditions for each temperature for 12 weeks (4 ℃, 25 ℃, 37 ℃, and 45 ℃). The pH of the experimental group containing 1% of CBD tended to decrease more than that of the control group. As a result of measuring the change in the content of CBD in the cream under each temperature for 12 weeks using HPLC, the difference in the amount of decrement according to temperature was confirmed. It was confirmed that as a result of measuring the chromaticity using color difference meter, the yellowness of the cream containing CBD increased according to the increase by the storage period and temperature compared to the control group. From the above results, it was confirmed that the content decrease and color change according to the temperature of the pH 5 ~ 6 cream formulation containing CBD. When CBD is applied to medicine and cosmetic formulations in the future, it is considered that research and development should be conducted in consideration of the change in the quantity and physicochemical quality of CBD under the temperature.

Purpose: In this study an examination was done of the effects of the American Society of PeriAnesthesia Nurses (ASPAN) Evidence-Based Clinical Practice Guidelines on body temperature, shivering, thermal discomfort, and time to achieve normothermia in patients undergoing total knee replacement arthroplasty (TKRA) under spinal anesthesia. Methods: This study was an experimental study with a randomized controlled trial design. Participants (n=60) were patients who underwent TKRA between December 2011 and March 2012. Experimental group (n=30) received active and passive warming measures as described in the ASPAN's guidelines. Control group (n=30) received traditional care. Body temperature, shivering, thermal discomfort, time to achieve normothermia were measured in both groups at 30 minute intervals. Results: Experimental group had slightly higher body temperature compared to control group (p=.002). Thermal discomfort was higher in the experimental group before surgery but higher in the control group after surgery (p=.034). It decreased after surgery (p=.041) in both groups. Time to achieve normothermia was shorter in the experimental group (p=.010). Conclusion: ASPAN's guidelines provide guidance on measuring patient body temperature at regular intervals and on individualized and differentiated hypothermia management which can be very useful in nursing care, particularly in protecting patient safety and improving quality of nursing.

We investigated mating conditions of photoperiod, illumination and temperature during mating periods, care temperature of queen before mating, mating period and number of queen per mating cage to improve mating rate of Bombus ignitus. Among photoperiodic regimes of 12L, 14L and 16L during mating periods, queen mated at 14L showed better results than at 12L and 16L in egg-laying characteristics and colony development. In case of illumination during mating periods, intensity of 1000 lux was more effective than at intensity of 100 lux and 2000 lux in mating B. ignitus queen. Mating temperature and care temperature of queen before mating favorable for B. ignitus queen were $22-25^{\circ}C$ and $19^{\circ}C$, respectively. The period need to mating B. ignitus queen was 3 days, and the number of queen suitable per mating cage of $55{\times}45{\time}65\;cm$ was 30.

Recently, there have been attempts to claim the hair moisturizing effect for a hair care product, however there has not yet been an official evaluation method because heating temperature for hair has not been established. This study was conducted to establish a quantitative evaluation for hair water content. In order to observe the behavior of water inside hair, heat was applied to hair with various temperatures using thermogravimetric dry residue. As the heating temperature increased, the amount of moisture released from the hair increased. As a result of evaluating hair using a differential scanning calorimeter (DSC), a unique phenomenon in which a rapid endothermic reaction occurs around 75 ℃ was observed. This phenomenon was also observed in different ethnic hair. In hair that damaged the hair cuticle barrier with oxidation and heat, this rapidly rising endothermic reaction temperature occurred at 77 ℃, which was slightly higher, and 73 ℃ was observed when this hair was applied with polar oil, conditioning polymer, or keratin protein. To determine how this reaction affects the hair surface, friction test was performed using an atomic force microscope. When heated above 75 ℃, cuticle friction increased, however when heated above 90 ℃, there was no change in hair cuticle friction. Finally, it was confirmed that around 75 ℃ is the critical temperature at which desorption of water bound to the hair occurs. It is suggested that a heating temperature of 75 ℃ is the optimal temperature for detecting and quantifying the moisture content of hair, and that approximately 10% detected at 75 ℃ can be a standard value for hair moisture content.

The objective of this study was to evaluate the microbiological quality of heating and after-heating processed foods for implementation of a HACCP system in day-care center foodservice operations. The evaluating points were microbial assessment and temperature of foods during receiving, cooking, and serving in heating process. In non-heating process, in addition to monitoring microbial assessment of food during preparation, cooking, and serving steps, the microbial populations of employees' hands and utensils and serving temperature were also evaluated. Microbiological quality was assessed using 3M Petrifilm$^{TM}$ to measure total plate count and coliforms for foods and utensils and Staphylococcus aureus for hands in five Gumi day-care centers. Microbiological quality assessment for foods and utensils is summarized as follows. Microbiological quality of the heating processed foods was satisfactory for cooking and serving steps. The internal temperature of food was above 74$^{\circ}C$. However, temperature control before the serving step was not achieved due to inappropriate time management between the cooking and serving steps. In the after-heating process, the total plate counts of boiled mungbean sprouts salad, blanched spinach salad, com vegetable salad were below the standard at the serving step. The majority of samples showed that coliforms exceeded the norm, which is thought to be the result of the cross-contamination from utensils. These results suggest that it is essential to educate employees on the importance of hand washing and of avoiding cross-contamination by using clean, sanitized equipment to serve food in the after-heating process. Establishing Sanitation Standard Operating Procedures (SSOPs) is an essential part of any HACCP system in day-care center foodservice operations.

The needs for the home care of postpartum mothers and their infants are increasing, but the quality control of home care nurses is not developed yet. The objective of this study is to develop assessment - intervention algorithms for the home care of postpartum mothers and their infants. We can use these algorithms when we assess the client's condition, and find appropriate nursing interventions. Also, these algorithms can offer guidelines for home care nurses, so that standardization of home care can be attained. Common problems for postpartum mothers are postpartum hemorrhage, abnormal vaginal discharge(endometritis), episiotomy pain, breast problems, breastfeeding difficulty, edema, urinary dysfunction and defecation difficulties. Also, commom problems for infants are abnormal body temperature, tarchycardia, respiratory problem, neonatal jaundice, cord problem, abnormal stool, breast feeding, and bathing. These algorithms can be used as a basis for the development of computerized infomation system for the home health care.
