  • These studies were conducted to investigate the prey consumption and suppression of cotton aphid and green peach aphid by Chrysopa pallens Ramber as a predator. The 3$^{rd}$ instar of C. pallets fed on 29.8, 77.9, 133.6, and 155.7 individuals of apterous Aphis goussypii Glover a day at 17,22, 27, and 32$^{\circ}C$, respectively. A preovipositing female fed on 73.1 individuals, ovipositing female on 86.6 individuals, and adult male on 69.7 individuals of apterous Myzus persicae (Sulzer) a day at the 27$^{\circ}C$. The functional response curve of the larvae and adults of C. pallens to the densities of A. gossypii indicated Helling’s Type II: the consumption of prey by the C. pallens increased with the prey density but the consumption rate decreased. The attack rate of 3rd instar of C. pallens was the highest among the 2nd instar, 3$^{rd}$ instar, adult male and adult female, and handling time was the shortest. The critical ratio of the predator vs. the prey to effectively suppress the population of A. gossypii by releasing C. pallets eggs was 1 : 4 on red pepper and egg plant, and 1 : 3 on cucumber. Release of second larval stave of C. pallens at the ratio of 1 : 30 of the predator vs. the prey controlled satisfactorily A. gossypii on red pepper, and 1 : 20 on cucumber and tomato. The three-times introduction of the eggs of C. pallens was as effective as four applications of insecticides from mid-June to late September.r.

  • Background: Studies on anesthetized dogs regarding pulse pressure variation (PPV) are increasing. The influence of respiratory rate (RR) on PPV, in mechanically ventilated dogs, has not been clearly identified. Objectives: This study evaluated the influence of RR on PPV in mechanically ventilated healthy dogs after hemorrhage. Methods: Five healthy adult Beagle dogs were premedicated with intravenous (IV) acepromazine (0.01 mg/kg). Anesthesia was induced with alfaxalone (3 mg/kg IV) and maintained with isoflurane in 100% oxygen. The right dorsal pedal artery was cannulated with a 22-gauge catheter for blood removal, and the left dorsal pedal artery was cannulated and connected to a transducer system for arterial blood pressure monitoring. The PPV was automatically calculated using a multi-parameter monitor and recorded. Hemorrhage was induced by withdrawing 30% of blood (24 mL/kg) over 30 min. Mechanical ventilation was provided with a tidal volume of 10 mL/kg and a 1:2 inspiration-to-expiration ratio at an initial RR of 15 breaths/min (baseline). Thereafter, RR was changed to 20, 30, and 40 breaths/min according to the casting lots, and the PPV was recorded at each RR. After data collection, the blood was transfused at a rate of 10 mL/kg/h, and the PPV was recorded at the baseline ventilator setting. Results: The data of PPV were analyzed using the Friedman test followed by the Wilcoxon signed-rank test (p < 0.05). Hemorrhage significantly increased PPV from 11% to 25% at 15 breaths/min. An increase in RR significantly decreased PPV from 25 (baseline) to 17%, 10%, and 10% at 20, 30, and 40 breaths/min, respectively (all p < 0.05). Conclusions: The PPV is a dynamic parameter that can predict a dog's hemorrhagic condition, but PPV can be decreased in dogs under high RR. Therefore, careful interpretation may be required when using the PPV parameter particularly in the dogs with hyperventilation.

  • Purpose: This study was to prepare the basic data for prevention of colorectal cancer and protection against its spread. Method: The subjects for the study were 204 patients with colorectal cancer from the G.S. wards of five general hospitals in Busan for the period of June 1 to September 1, 2001. The instrument used was a questionaire which was developed by Junho Shin(1995). The data was analyzed by descriptive statistics, McNemar test, ${\chi}^2$ test, paired t-test, and ANOVA. Result: 1. 57% of the studied subjects were male, 42.7% were more than 60 years old, 54.9% were of standard physique, 49.5% were the Buddhists, 50.5% were the middle or high school graduates, 83.8% were city dwellers, 48% were jobless, 69.6% had no-history of alimentary disease, 44.1% had no-family history of cancer, 82.8% were married. 2. Constipation (${\chi}^2=36.45$, p=0.0001) in clients showed a significant positive association for the prediagnosed, but diarrhea(${\chi}^2=3.947$, p=0.047) showed a significant positive association for the post-diagnosed. The preference for high seasonings(t=6.23, p=0.0001) and animal fat (t=8.35, p=0.0001) was higher significantly in the pre-diagnosed, but physical activities(${\chi}^2=30.22$, p=0.0001), an eutrophic or tonic medicine(${\chi}^2=30.22$, p=0.0001), was of and vegetables(t=-6.20, p=0.0001) was higher significantly in the post-diagnosed. 3. There were significant differences in the life style of the pre-diagnosed according to the general characteristics except religion. Conclusion: Results of the above study reveal we should be very sensitive to the change of defecation styles and consider the necessity of improving life styles as regards eating habits. When an education program is developed, the general characteristics of the subjects need to be considered.

  • The purpose of this study was to identify the effect of body positioning on $PaO_2$, $SpO_2$, systolic blood pressure, diastolic blood pressure, pulse, and respiration(above all defined physiologic index), of patients with unilateral lung disease. The subjects for this study were eleven patients admitted to I.C.U. of K.H.M.C. with a diagnosis of unilateral lung disease confirmed by chest X-ray and the attending doctor, from January 30th. to April 20th. 1999. A quasi-experimental repeated-measures cross-over design was used to compare three body positions(semi-Fowler's, lateral decubitus with good lung dependent, and lateral decubitus with diseased lung dependent). Each subject spent 30 minutes in semi-Fowler's position and 2 hours in good lung dependent position and diseased lung dependent position. Starting in the semi-Fowler's position, then in the lateral position with the good lung dependent or the diseased lung dependent as assigned in random order. Thirty minutes after each positioning, arterial blood sample was analyzed. Measurements of all physiologic index were recorded at the specified intervals(0, 30, 60 90, and 120 minutes) in good lung dependent and diseased lung dependent position. Statistical comparison of $PaO_2$ value was done using the Wilcoxon Signed Rank Test, and Multivariate repeated-measures analysis of variance was performed to analyse the within-subject effect of two dependent position for 2 hours on the five dependent variables: (1) $PaO_2$ (2) $SpO_2$ (3) systolic blood pressure (4) diastolic blood pressure (5) pulse. The results obtained were as follows: 1. The $PaO_2$ value in the good lung dependent position was significantly higher than the $PaO_2$ value in the diseased lung dependent position(Z=-2.8451, p=.002). 2. The $PaO_2$ value in the good lung dependent position was significantly higher than the $PaO_2$ value in the semi-Fowler's position (Z=-2.6673, p=.003). 3. The difference between the $PaO_2$ value in the semi-Fowler's position and the $PaO_2$ value in the diseased lung dependent position was not significant(Z=-1.2448, p=.10). 4. There were no statistically significance in the trends of physiologic index in the good lung dependent position and the diseased lung dependent position. From the results, it may be concluded that the good lung dependent position is the most effective position for patients with unilateral lung disease that improve oxygenation. Identification of positioning over time may be need further studies.

  • The purpose of this study was to determine the effects of linear polarized near-infrared ray radiation on experimental pain threshold in healthy adult subjects. Thirty healthy adult subjects were divided into 5 groups: 1) group 1, super lizer radiation at 0 % ; 2) group 2, super lizer radiation at 10 % ; 3) group 3, super lizer radiation at 20 % ; 4) group 4, super lizer radiation at 40 % ; 5) group 5, super lizer radiation at 80 %. The polarized near-infrared ray radiation was applied on LI 4 point of subject's right hand at a fixed time for 30 second. Experimental pain threshold were measured with electrical current on the right hand at 5 intervals for each radiation: 1) pretreat; 2) posttreat ; 3) posttreat of 1/2 hr ; 4) posttreat of 1 hr ; and 5) posttreat of 2 hrs. Data were analyzed using analyses of variance with repeated measures for pain threshold. No significant interaction between power output and time for pain threshold was found. Significant effects of power output and time for experimental pain threshold were found. Significant increase was noted in experimental pain threshold in group 4 and group 5 at posttreat, posttreat of 1/2, 1 hr and 2 hrs as a result of the applications of the polarized near-infrared ray radiation. This study indicate that polarized near-infrared ray radiation with above 40 % of power output increases pain threshold, thus possibly increasing options in choosing radiation output for treating pateint with pain. Further study is needed to compare the effects of these radiation in patients with clinical pain.

  • The purpose of this study was to implement a program of combined muscle stregth and proprioceptive exercises and to examine the impacts of these exercises on functional ankle instability(FAI). Experiments were conducted with 30 adult males and females in their 20s, and the exercise programs were implemented three days per week for four weeks. FAI was defined as a feeling of giving way after an ankle sprain and having a Cumberland ankle instability tool score of 24 points or less. The study subjects were randomly assigned to either a control group, a muscle-strengthening exercise group, or a combined muscle-strengthening and proprioceptive exercise group consisting of 10 subjects each. A Biodex isokinetic dynamometer was used to assess the subjects'ankle strength at selected speeds of $60^{\circ}/sec$ and $120^{\circ}/sec$. The peak torque % body weight showed significant differences in plantar flexion, dorsiflexion, inversion, and eversion. There were also significant differences in proprioception. The results suggest that applying combined muscle-strength and proprioceptive exercises to subjects with FAI is a more effective intervention than applying only muscle-strengthening exercises.

  • The government of Korea enacted the National Health Promotion Act in 1995, and set aside funds for national health promotion, endeavoring to reduce the smoking rate of its citizens. Consequently, smoking rates in all age groups of both sexes were lowered during the period of 1999-2003 when legal backing and financial support for no-smoking policies from the national health promotion funds were provided. The decrease in the smoking rate is attributed to the combined effort of the fact that enactment of related acts, their implementation, financial support, and education and publicity 'campaigns on no smoking. However, at the current pace of decreasing the smoking rates, it will be difficult to achieve the Health and Welfare Ministry's smoking rate goal of30% among adult males by 2013. Thus, related acts should be reshaped, corresponding support should be increased, and financial support should also be provided to implement comprehensive no-smoking policies. Also, budgets should also be alloted to establish a system of providing feedback on the monitoring and evaluation of both short-term and long-term no-smoking business planning and implementation.

  • The purpose of this study was to define the degree of the resourcefulness and the health-promoting behavior of cancer patients, to identify the relationship between the resourcefulness and the health promoting behaviors and to provide the basis for strategic nursing intervention. This study was conducted by an exploratory survey. Data were collected by self-reported questionnaires from 97 cancer patients in a university hospital in Tae-Gu from September to December of 1998. The sample data were collected by using a convenient sampling method. The following instruments were used in the study after some adaptation : Park Chai Soon's Health Promoting Lifestyle Profile, Oh Pok Ja's instrument for health promotion behavior and the Rosenbaum self-control schedule(SCS). The reliability of instruments was tested with Chronbach'alph(.79-.89). Data was analyzed by using the SAS program. T-test, ANOVA, and Pearson's coefficients of correlation. The results of this study were as follows: First, the average score of the resourcefulness variable was 22.20; the range of the score was from -30 to +81 The average score of the performance in the health promoting behavior variable was 96.13; the range of the score was from 39 to 137 Second, the resourcefulness variable was significantly different from such demographic factors as gender and perceived health status, but there was no statistically significant difference between the demographic factors and the health promoting behavior variable, except that of perceived health status. Third, the performance in health promoting behavior of cancer patients was significantly correlated with the resourcefulness of cancer patients(r= .50) In conclusion, resourcefulness was identified to be an important variable that could contribute to promote health-promoting behavior.
