  • This study was conducted to compare the aspects of behavior between miniature pigs and conventional sows during gestation and lactation periods. Miniature pigs and conventional sows at 3 parity were used in this experiment with 4 pigs per treatment. The behavioral patterns and stereotyped behaviors were observed on day 60 and 90 of gestation, at farrowing, and on day 10 of lactation before and after the feeding. On 60 and 90 days of pregnancy, both treatments showed the tendency of frequent lateral lying rather than other postures. On ventral lying, eating and drinking, miniature pigs spent more time than conventional pigs at day 90 of gestation (P<0.01, P=0.0539, P<0.05, respectively). The occurrence of stereotyped behaviors included bar biting and bar mouth chewing. At 90 day of pregnancy was observed, conventional pigs was higher than miniature pigs (P<0.05). At farrowing, miniature pigs spent more time on ventral lying, standing and walking than conventional sows (P<0.05), however, there were more frequency of drinking and eating. And on day 10 of lactation, there was no significant difference in stereotyped behaviors between miniature pigs and conventional sows. In conclusion, miniature pigs were generally more sensitive than conventional sows although sows were reared in stall during gestation and lactation period and the behavioral pattern during lactating period showed the similarity between miniature pigs and conventional sows for protection of nursing pigs. In consideration of the general reproductive performance of conventional sows, the high sensitivity and stress of miniature pigs did not affect the reproductive performance of miniature pigs.

  • Mammals act as an important role in maintaining ecosystem, but direct observation is very difficult. Nevertheless, in order to understand the impact of various changes about a sudden environment, long-term monitoring through direct investigation is essential. This study investigated home range analysis using GPS tracking device and behavioral ecology of Korean waterdeer (Hydropotes inermis), indigenous and native species in Korea. Studies on ecological characteristics and home range of Korean waterdeer are insufficient. Therefore, we studied home range using the GPS technique for critical point of existing research. Data showed the active movement in daytime ($44.1km^2$) than night ($30.0km^2$) and large area of activity in winter ($3.7km^2$) and spring ($44.1km^2$) than summer($0.04km^2$) and autumn ($0.01km^2$). The most used area of Korean waterdeer was forested area and wetland, agricultural area, waters in order of frequency based on the land coverage map. Our research represents overall characteristics of Korean water deer due to measurement of area of activity. However, this research signified behavioral ecology for Korean waterdeer, and further investigation in necessary.

  • Red ginseng (RG, the extract of Panax ginseng Meyer) has various biological and psychological activities and may also alleviate fatigue-related disorders. The present study was undertaken to evaluate what kind of fatigue red ginseng alleviate. Animals were orally administered with 50, 100, 200, 400 mg/kg of RG for 7 days. Before experiments were performed. Physiological stress (swimming, rotarod, and wire test) are behavioral parameters used to represent physical fatigue. Restraint stress and electric field test to a certain degree, induce psychological fatigue in animals. Plasma concentration of lactate and corticosterone (CORT) were also measured after these behavioral assays. RG supplementation (100 mg/kg) increased movement duration and rearing frequency of restrainted mice in comparison with control. 100 and 200 mg/kg of RG increased swimming time in cold water ($8{\pm}4^{\circ}C$) while at 100 mg/kg, RG increased electric field crossing over frequencies. 50, 100 and 200 mg/kg RG prolonged running time on the rotarod and at 100 mg/kg, it increased balancing time on the wire. RG at those doses also reduced falling frequencies. RG supplementation decreased plasma CORT levels, which was increased by stress. Lactate levels were not significantly altered. These results suggest that RG supplementation can alleviate more the damages induced by psychological than physical fatigue.

  • The intensity and duration of sexual behavior in Bos indicus was assessed through the continuous observation of sexual receptivity. Two groups of cows were formed: only synchronized (n = 50) and other group further superovulated (n = 20). An intravaginal implant that released progesterone over 9 d was used. After removing the implant, 25 mg of $PGF_{2{\alpha}}$ was administered. In the superovulated group, the administration of 280 mg (Follicle stimulant hormone) FSH-P1 per cow with a decreasing dosage over 4 d was utilized. In both groups, behavioral observations began at the moment of implant removal. Sexual behavior was analyzed using a Kruskal-Wallis test to compare the mean of hours in estrus, effective mountings and number of mounts/hour during estrus. A nonparametric survival analysis was performed using the time in two ways: i) when an event happened it was placed in a 24 h timeframe and, ii) the time of observation in continuous form (96 h) assessing the difference between curves by the log rank test Chi-square. The only significant difference was the number of mounts/h during receptivity (p<0.05). In the superovulated group three periods of sexual activity during the day were identified, with these events being of greater frequency and duration than the synchronized group (p = 0.02); besides, the superovulated group began estrus before the synchronized group (p = 0.0035) when using the total period. In a simulation study, when the number of observations went from two (06:00-18:00) to three periods (06:00, 12:00 and 18:00) cows detected accurately (<6 h after the onset) increased more than 20%. The results show that superovulated cows presented greater intensity and duration of sexual activity in contrast with only synchronized animals.

  • The purpose of this study was to identify nursing interventions performed by neonatal nursing unit nurses. For data collection this study used the taxonomy of Nursing Intervention Classification(NIC : 486 nursing intervention) which was modified by McCloskey & Bulecheck(2000). The new 58 nursing interventions was translated into Korean, and then modified by pannel group, which consist of clinical experts and nursing scholars and finally the 419 nursing interventions was selected. The data were collected from 112 nurses. 168 nursing interventions were performed at least monthly by 50% or more of the nurses. The high frequency of performed nursing interventions were Family domain. 37 nursing interventions were performed at least once a day. The nursing interventions receiving the highest item mean score were neonatal care, neonatal monitoring, photo-therapy; neonate, bottle feeding and temperature regulation. 56 nursing interventions were rarely performed by 90% or more of the nurses. Most of them were in the behavioral domain. The rarely used interventions were urinary bladder training, art therapy, religious addiction prevention, religious ritual enhancement and bladder irrigation. Therefore, neonatal nursing units nurses used interventions in the Physiological: basic domain most often on a daily basis and the interventions in the behavioral domain least often. These findings will help in building of a standardized language for the neonatal nursing units and enhance the quality of nursing care. Further study will be needed to classify each intervention class and nursing activity and validate NIC in pediatric care unit.

  • The purpose of this study was 1) to investigate the food intake, dietary habits and life behavioral characteristics, and 2) to examine the relationship among these factors in a sample of adult Korean women. In October 2010, self-reported questionnaire survey was distributed to 200 women aged 30 to 65 in Gyunggi Province. Overall, 177 women participated and completed the survey. Most participants were married (97.2%) and housewives (83.6%). About 85% of respondents lived with their children. For comprehensive analysis, all respondents were divided into three age groups; 30~39, 40~49, and 50~65. The percent of intake of high protein foods such as meat and fish, eggs, and milk products was higher younger age groups (p<0.05). Moreover, age 30~39 group were more likely to eat potatoes (p<0.05) than age 50~65 group. However, age 50~65 women more frequently consumed seaweed than other age groups (p<0.01). Women who ate breakfast or dinner consumed a significantly higher frequency of vegetables, seaweed, potatoes, and kimchi (p<0.01). Additionally, women who ate breakfast with family more frequently consumed vegetables, fruit and kimchi. Furthermore, older women were likely to have less sleeping time than other groups. In conclusion, there were western dietary patterns among adult women and these dietary patterns were partly related to different life behavior and dietary habits. Considering that negative dietary habits of adult women can influence their family and health for the rest of their life, nutritional education programs based on changes in lifestyle should be developed.

  • Objcetive : Neuropathic pain sometimes arises from a partial peripheral nerve injury. This kind of pain is usually accompanied by spontaneous burning pain, allodynia and hyperalgesia. It has been well known that acupuncture is effective to the pain control from ancient time in Asia. However, it is not clear whether acupuncture can control neuropathic pain. The aim of the present study is to examine if acupuncture stimulation may be effective to the mechanical allodynia in a rat model of neuropathic pain. Methods : To produce neuropathic pain, under sodium pentobarbital anesthesia, the right superior caudal trunk was resected between the S3 and S4 spinal nerves. After the neuropathic surgery, we examined if the animals exhibited the behavioral signs of mechanical allodynia. The mechanical allodynia was assessed by stimulating the tail with von Frey hair (bending force : 2.0g). three or 6 weeks after the neuropathic surgery, acupuncture stimulation was delivered to Houxi (SI 3) as the following parameters (2HZ frequency, 0.07mA intensity and 3msec duration) for 30 minutes. Results : The stimulation of Houxi (SI 3) acupoint relieved the behavioral signs of mechanical allodynia. Conclusion : Our results suggest that acupuncture can control the mechanical allodynia of neuropathic pain.

  • The purpose of this study was to investigate the psychosocial factors influencing dairy product consumption of female university students in Daejeon. The Theory of Planned Behavior provided the basis for this study. As a result of the pilot-study, 18 behavioral beliefs, 8 normative beliefs, and 12 control beliefs were identified. The subjects (n=236) were grouped into a high-consumption group (1 serving/day, n=117) and a low consumption group (< 1 serving/day, n=119). The data were analyzed using t-tests or $\chi$$^2$-tests. Among the general characteristics, there were significant differences in the amount of pocket money spent per month, residence type (p<0.01), weight, frequency of exercise and perceived health status (p<0.05) of the subjects. With respect to the 18 behavioral beliefs, the high consumption group responded less negatively on ‘eating dairy foods would not be convenient’ than the low consumption group (p<0.05). None of the subjective normative items were significantly different between the two groups. However, notable differences were found in regard to the control beliefs (8 out of 12 control beliefs). These included overall control over consuming dairy products (p< 0.001), as well as specific beliefs regarding barriers such as easy spoilage of dairy products, the cost, eating them for snacks and dislike for them (p<0.05). In addition, specific situations, such as ‘when I want them I get them’ (p<0.01), eating out and the availability of dairy foods at home (p<0.05) were significantly different between the two groups. The high consumption group showed more control over these barriers or situations. These results suggest that nutritional education for young female adults should incorporate strategies to increase their perceived control over the consumption of dairy products by removing barriers and including environmental approaches which address the availability issues.
