  • This study is to investigate the environmental levels and trend of dioxins, which was the 3$\^$rd/ year of environmental monitoring research for endocrine disrupting chemicals since 1999. Total 282 samples were analyzed from 115 sites including 26 sites of airs, 43 sites of waters, 11 sites of sediments and 35 sites of soil, which were the same as those of investigated sites in 2000. Sampling period was from June 2001 to June 2002. Target chemicals were seventeen species of 2,3,7,8-chlorine-substituted PCDD and PCDF congeners and were analyzed by the standard methods, established by National Institute Environmental Research (NIER). The average concentration of dioxins in air decreased from 0.324 pg-TEQ/N㎥ in 2000 to 0.287 pg-TEQ/N㎥ in 2001, and those in water and soil were 0.073pg-TEQ/L and 1.703pg-TEQ/dry g, respectively, which was the less values detected in 2000. In sediment, however, the value was 0.086pg-TEQ/dry g, which was the increase from the value of the year 2000. The concentration range of dioxins in air for 26 sites in 17 regions detected were 0.013∼l.664pg-TEQ/N㎥, 4 sites from those were exceeded the Air Quality Standards of Dioxin in Japan (0.6 pg-TEQ/N㎥). The tolerable daily intake of dioxins was calculated at the highest level (1.664) in air, with referring the soil and food data from Japan, was calculated to be 2.85pg-TEQ/kg/day, which was below the level of 4 pg-TEQ/kg/day suggested in KFDA(Korea). While the average concentration of dioxins in 15 big cities was 0.190 pg-TEQ/N㎥, that in 8 medium/small cities constituting an industrial complex was 0.558 pg-TEQ/N㎥. In water, the concentration range detected were 0∼0.946pg-TEQ/L and the trend of the average concentrations shows an increase from those of 1999 but decreased from those of 2000, any sites however were not exceeded the Water Quality Standards of Dioxin in Japan (1 pg- TEQ/L). In soil. the detected range were 0∼43.333 pg-TEQ/dry g and the average concentration decreased, compared with the results of 2000. According to the monitoring results by land utilization, the detected range were 0∼43.333pg-TEQ/dry g in farmland, 0.017∼0.601 pg-TEQ/dry g in the industrial area, 0.005∼0.049pg-TEQ/dry g in the park and 0.008∼1.825 pg-TEQ/dry g in the rest. In sediment, the detected range increased from 0∼0.244 pg-TEQ/dry g to 0∼0.537 pg-TEQ/dry g, based on the results of 2000. For the proper control of dioxins, continuous monitoring needs to be performed and in addition, the dioxin inventory should be prepared for major sources through the dioxin emission survey. These results would provide sound and solid basis for proper decision making of dioxins management like establishment of environmental quality standards in Korea.

  • The purpose of this present study is not only to investigate mutual relationship between general values and clothing behaviors, but to analyize the differences in clothing behaviors in view of socio-economic backgrounds, such as professions, social classes, educational levels, monthly income, etc. For the measurement of the general values, a total of 45 questions were made use of from both part I and part II of 'The study of General Values' jointly developed by Allport-Vernon-Lindzey, while for the measurement of the clothing behaviors were used questions selected from 'The clothing variables Inventory' developed by Creekmore and from those previously used in our country for the same purpose. Data were obtained from 460 Persons and the selected sample was composed of 238 Persons from the upper class and of 222 persons from the lower class. The former class is mainly represented by government officials, doctors, company directors, professors, while the latter by factory workers, clerks, drivers. Analysis of the data in this present study reached its conclusions as follows ; 1. Among the general values valiables, the selected group in this study ranked, theoretical values' first, 'political values' 'econmic values', 'social values', aesthetic values', 'religious values' in that order, and also among the clothing behaviors variables it ranked in the following order ; economy' 'modesty' 'aesthetic' 'conformity' 'status symbol'. 2. A significant relationship between general values and clothing behaviors was found as follows ; there are negative relationships between 'theoretical values' and 'aesthetic', 'status symbol', between 'aesthetic values' and 'conformity', between 'social values' and 'status symbol', between 'political values' and 'conformity', on the one; there are positive relationships between political values' and 'status symbol', between religious values' and 'aesthetic', on the other, 3. In view of profession, it was found that a group of company directors placed the most importance upon 'status symbol', a group of factory workers upon 'economy', a group of drivers upon 'conformity' among the clothing behaviors. In light of social classes, 'economy' was given a high priority by the lower class, and 'status symbol' by the upper class, respectively. Considering educational levels, it was found that the highly educated class placed more emphasis on 'status symbol' and the lower educated class showed their preference to 'economy'. In view of monthly pay, 'conformity' was given a top priority by the middle class, and 'status symbol' by the upper class. 4. As a result of investigating the influence that one's age and marriage effect on clothing behaviors, significant differences were found among the three clothing motivations of 'aesthetic', modesty', 'status symbol'.

  • Purpose: The purpose of this study was to elucidate the effects of spiritual nursing intervention on the spiritual well being and depression levels of hospice patients. Method: The data for this study were collected from 62 patients who were admitted to the hospice care unit from July 28, 2002 to October 31, 2002 in D city K hospital. Subjects were 31 members of the experimental group and 31 members of the control group. It was devised with a nonequivalent control group pretest posttest design. The spiritual nursing intervention was given by using the therapeutic use of self. Scripture. prayer. Hymn and music. use of church community involvement and referrals to pastors according to the assessment of patients' spiritual needs for 3 weeks(total 12 times and 1 hour per each intervention). Sangsoon Choi (1990) and Jungho Kang(1996)'s spiritual well being scale. which was modified from Palautzian and Ellison (1982)'s spiritual well being scale, was used to investigate patients' spiritual well being. To investigate the level of depression. OkHyun Song(1977)'s Depression Scale, which was modified from Zung(1965)'s Depression Inventory, was used. Data were analyzed by $x^2$-test. t-test. and repeated measures ANOVA with SPSS/Win 10.0 program. Results: 1. The 1st hypothesis. 'total spiritual well being score in the experimental group, who received the spiritual nursing intervention, will be higher than the control group who did not receive the spiritual nursing intervention' was supported (F=6.28, p=0.015, Interaction: p=0.000). 2. The 1 lst sub hypothesis, 'religious well being score in the experimental group, who received the spiritual nursing intervention, will be higher than the control group who did not receive the spiritual nursing intervention' was supported(F=12.75, p=0.001 Interaction: p=0.000). 3. The 1 2nd sub hypothesis, 'existential well being score in the experimental group, who received the spiritual nursing intervention, will be higher than the control group who did not receive the spiritual nursing intervention' was supported(F=6.87, p=0.016, Interaction: p=0.000). 4. The 2nd hypothesis, 'depression level in the experimental group, who received the spiritual nursing intervention, will be lower than the control group who did not receive the spiritual nursing intervention' was supported (F=10.45, p=0.002, Interaction: p=0.000). Conclusion: From the above results, spiritual nursing intervention was an effective program to improve the spiritual well being state and decrease the depression levels of the hospice patients. In the future, with spiritual intervention. which the researcher developed, is applied in the nursing field, the hospice patients can have comprehensive well being including spiritual well being and die peacefully.

  • There have been many studies on patients who suffer from anxiety disorders. However, there is been not enough attention on the difference in the level of between the two populations with and without anxiety disorders. This study was performed to investigate the difference in the ANS responses induced by fear in children. Experimental procedures were as follow: All subjects were in upper grade levels in elementary school. ANX(anxiety) scales of PIC(Personality Inventory for Children) were used to measure fear anxiety. Audio-visual clips were used as stimulus to provoke fear emotion. Baseline of physiological signals, ECG, PPG, EDA, and SKT, were measured for 30 seconds before the fear stimulus. Physiological signals were then recorded for 2 minutes while fear is evoked. Psychological and physiological responses were analyzed. All the children reacted to the fear stimulus with high intensity of fear. Physiological responses showed that SKT, SCR, NSCR, HR, RSA, RESP, HF were increased, while R-R was significantly decreased, respectively, during the period of fear induction. Analysis of the level of anxiety and the physiological responses produced by the experience of fear revealed a statistically significant positive correlation in SKT, HR, and RSA. In other words, the higher the level of anxiety, the higher the levels of SKT, HR, and RSA when children experienced fear in conclusion, it is confirmed through this research that physiological responses to fear is associated with the level of anxiety each individual.

  • Objectives : Perceived stress scale is a self-report inventory to estimate the degree of individual perceived stress in daily life. The aim of this study was to introduce this scale and test the reliability and validity of the Korean version of PSS. Methods : The total of 154 female hospital workers were included in this study. The survey questionnaires were conducted for demographic information. All participants were required to complete PSS, Hamilton Anxiety scale and Beck Depression Inventory. Reliability and validity studies were conducted and internal consistency was examined. Results : The mean score of the PSS reported in this sample was $20.69{\pm}4.56$. The overall Cronbach's alpha was 0.819, and the test-retest reliability coefficient was 0.66. PSS had a significant positive correlation with the HAM-A(r=0.49, p<0.01), and the BDI(r=0.55, p<0.01). Factor analysis yielded 2 factors with eigenvalues of 3.924 and 2.608, accounting for 65 percent of variance. Factor 1 represented "stress" and factor 2 represented "control of stress". Conclusions : This study indicates that the PSS is appropriate for estimating the perceived stress levels. These results support the use of PSS in large sections of the population in Korea.

  • Numerous research reports have substantiated the role of stressful life events in relation to the onset of health changes. The relationship tends to hold across different age groups. Theoretically, adolescence has been considered a developmental crisis period of great stress, impoverished coping skills and high vulnerability to biological, social and psychological demands. The research problem addressed by this study was to examine the relationships between stressful life events and health symptom patterns, and the effect of two variables, coping and social, support, theoretically considered to mediate the relationship between stress and health symptoms in adolescents. The following five hypotheses were tested in this research : 1. Health symptoms are positively related to stressful life events in adolescents, 2. Health symptoms are negatively related to coping in adolescents, 3. Health symptoms are negatively related to social support in adolescents, 4. When coping is controlled, the relationship between health symptoms and stressful life events will decrease, and 5. When social support is controlled, the relationship between health symptoms and stressful life events will increase. The study subjects consisted of 1090 high school students of the metropolitan city of Seoul. The following sampling procedure was used : 1. Of the 169 high schools in nine school administrative districts in the city, a proportional sample of ten schools was selected. 2. One class from each of the freshman and sophomore was randomly selected and all the students who were in the sampled class were used as the study sample. The study was limited to freshman and sophomore adolescents, aged 15 to 18(mean=16.6). Of the 1090 subjects 688(63%) were boys and 402(37%) were girls. An Adolescent Inventory of Stressful Life Events, a Health Symptom Questionnaire and an Adolescent Coping Inventory were adapted for this study. The Norbeck Social Support questionnaire was utilized to collect the data on perceived social support. Five high school teachers in the areas of school health and counselling reviewed the items of each questionnaire for content validity. A pilot study was undertaken to ascertain reliability. Fifty three high school students responded to the questionnaires and gave their opinions on the items. For stressful life events, health symptoms, coping, and social support, the Cronbach's alpha's on the study were .70, .94, .77, and .76, respectively. Research assistants attended all the sampled classes with the school proctor to explain the purpose and procedures of the study to the students. The questionnaires along with a ballpoint pen were distributed to the students who were asked to complete each item. The research assistants left the ballpoint pen with the students as a gift for their cooperation. An average of 50 minutes was required to complete the questionnaires. Using an SPSS, the first, three hypotheses were tested using Gamma, a measure of association for ordinal variables. Partial gamma was used to test the fourth and fifth hypotheses. Patterns of elaboration described by Babbie were selected to interpret the relationship of the three variable analyses. The significance of gamma was determined by Chisquare at a .05 level of significance. There was a positive relationship between health symptoms and stressful life events(Gamma=.35, p=.000). Thus the first hypothesis was supported. Unexpectedly, coping was positively related with health symptoms(Gamma=.13, p=.000). That is, the higher the coping levels, the greater number of health problems. The third hypothesis, the higher the level of social support, the fewer the health symptoms, was not accepted in this adolescent study group. When coping was controlled, under the condition of low coping the association between health symptoms and stressful life events increased significantly to a partial gamma of .39, and under the condition of high coping it was .30. According to the elaboration model, when one partial relationship is the same or greater than the original and the other is smaller, the control variable should be considered to be specifying the conditions. When social support was controlled the relationship between stressful life events and health symptoms increased under the condition of low social support, but with high social support, the relationship decreased. Both partial gamma were statistically significant at .05 level(.43 and .26 relatively). It can be interpreted that stressful life events are strongly and positively related to health symptoms under the condition of low social support, however this relationship can not be expected with high social support. Thus, the last two hypotheses were conditionally sustained. In this study, the relationships between stressful life events and health symptoms, and the specified me diating roles of coping and social support were found to have statistical interaction. This finding supports the theoretical position of this study. It suggests that stressful life events would create high susceptability to biological social and psychological health symptoms and coping and social support buffering the relationship between stressful life events and health symptom. The findings of this study have implications for nursing practice. When adolescents are confronted with non-developmental life events that are perceived as stressful, nurses should recognize the evidence of the stress-buffering effect of coping and social support on health symptoms and utilize the diverse sources of social support that are readily available to adolescents.

  • Purpose: It has been reported that children with chronic pain have higher levels of anxiety than age-matched controls. Therefore, this study was designed to determine the relationship between anxiety and recurrent abdominal pain in elementary school children. Methods: In 2005, we surveyed 1,254 elementary school children (592 boys and 662 girls) whose ages ranged from 7 to 12 years. The degree of trait and state anxiety was compared between agroup suffering from intermittent abdominal pain, a group suffering from recurrent abdominal pain and a normal control group following the Korean version of Spielberger's State-Trait Anxiety Inventory YZ form (STAI-YZ). Results: 709 (56.5%) and 69 (5.5%) of the patients reported intermittent abdominal pain and and recurrent abdominal pain, respectively, during the 12 month period before this study was conducted, and trait and state anxiety values for each of these groups was 116 (9.3%) and 63 (5.0%), respectively. In addition, the State-Trait Anxiety score was significantly higher in the group with intermittent abdominal pain and RAP than the anxiety score of the normal control group. Additionally, the STAI-YZ score increased in proportion to the severity of abdominal pain, but was not correlated with the duration, frequency, onset time or location of abdominal pain. Furthermore, the proportion of the group with abdominal pain in the group that had trait or state anxiety was significantly higher than the proportion of the group that did not have trait and state anxiety. Conclusion: Recurrent abdominal pain during childhood is correlated with state and trait anxiety, therefore, psychological factors, such as anxiety duringtreatment, must also be considered when determining the cause of recurrent abdominal pain.

  • The wetland ecosystem is a complex products of various erosion force, accumulation as water flows, hydrogeomorphic units, seasonal changes, the amount of rainfalls, and other essential element. There is no single, correct, ecologically sound definition for wetlands because of the diversity of wetlands and the demarcation between dry and wet environments occurs along a continuum, but wetland plays various ecosystem functions. Despite comprehensive integration through classification and impact factors there is still lacking in systematic management of wetlands. Classification system developed by the USFWS(1979) is hierarchical progresses from systems and subsystems at general levels to classes, subclasses, dominance types, and habitat modifiers. Systems and subsystems are delineated according to major physical attributes such as tidal flushing, ocean-derived salts, and the energy of flowing water or waves. Classes and subclasses describe the type of substrate and habitat or the physiognomy of the vegetation or faunal assemblage. Wetland classes are divided into physical types and biotic types. For the wise management of wetlands in Korea, this study was carried out to examine methodology of USFWS classification system and discuss its application for Korean wetland hydrogeomorphic units already known. Seven wetland types were chosen as study sites in Korea divided into some different types based on USFWS system. Three wetland types belonging to palustrine system showed no difference between Wangdungjae wetland and Mujechi wetland, but Youngnup of Mt. Daeam was different from the former two types at the level of dominant types. This fact means that setting of classification system for management of wetland is needed. Although we may never know much about the wetland resources that have been lost, there are opportunities to conserve the riches that remain. Extensive inventory of all wetland types and documentation of their ecosystem functions are vital. Unique and vulnerable examples in particular need to be identified and protected. Furthermore, a framework with which to demonstrate wetland characteristics and relationships is needed that is sufficiently detailed to achieve the identification of the integrity and salient features of an enormous range of wetland types.

  • Objectives: The experience of traffic accident is a kind of the psychosocial stressors to person. The traffic accident-related patients may show the psychophysiologic hyperarousal. So we examined the differences of psychophysiologic response between patients with and without the memory of experienceing a traffic accident. Methods: Twenty-four traffic accident-related patients were divided into two groups according to ther memory of a traffic accident. In psychological assessment, levels of anxiety and depression were evaluated by State-Trait Anxiety Inventory, Beck's Depression Inventory, and Hamilton Rating Scales For Anxiety and Depression. Heart rate, electrodermal response (EDR), and electromyographic activity (EMG) were measured by biofeedback system, and systolic and diastolic blood pressure by automated vital sign monitor during baseline, task, and rest periods. We utilized script-driven imagery technique as a stressful task. The patients listened to the script describing their own traffic accident experience and were instructed to imagine the event during the task period. Statistically analytic data were obtained from the differences of psychological and psychophysiologic data between two groups. Results: The memory group did not show significantly higher EDR than the none memory group, but showed higher tendency during baseline, imagery, and rest periods. The memory group showed significantly lower EMG than the none memory group during rest period. However, there were no differences in other psychophysiologic reponses between the two groups. Conclusion: Our results showed that the memory group had higher tendency in autonomic arousal level such as electrodermal response than the none memory group. We suggest that physicians need to minimize repetitive imagery of traffic accident (reexperience), and decrease the autonomic hyperarousal in the treatment of traffic accident-related patients.

  • Objectives: An Increased level of psychophysiologic arousal and diminished physiologic flexibility would be observed in patients with panic disorder compared with a normal control group. We investigated the differences of psychophysiologic response between patients with panic disorder and normal control to examine this hypothesis. Methods: Ten Korean patients with panic disorder who met the diagnostic criteria of DSM-IV were compared with 10 normal healthy subjects. In psychological assessment, levels of anxiety and depression were evaluated by State-Trait Anxiety Inventory, Beck's Depression Inventory and Hamilton Rating Scale For Anxiety and Depression. Heart rate, respiration rate, electrodermal response, and electromyographic activity were measured by biofeedback system (J & J I-330 model) to determine psychophysiologic responses on autonomic nervous system. Stressful tasks included mental arithmetic, video game, hyperventilation, and talking about a stressful event. Psychophysiologic responses were measured according to the following procedures : baseline(3 min)-mental arithmetic (3 min)-rest (3 min)-video game (3 min)-rest (3 min)-hyperventilation (3 min)-rest (3 min)-talking about a stressful event (3 min). Results: The baseline level of anxiety and depression, electrodermal response (p=.017), electromyographic activity (p=.047) and heart rate (p=.049) of patients with panic disorder were significantly higher than those of the normal subject group. In electrodermal response, patient group had significantly higher startle response than the control group during hyperventilation (p=.001). Startle and recovery responses of heart rate in the patient group were significantly lower than responses in the control group during mental arithmetic (p=.007, p=.002). In electrodermal response of the patient group, startle response was significantly higher than recovery response during mental arithmetic (p=.000) and video game task (p=.021). Recovery response was significantly higher than startle response in respiratory response during hyperventilation. Conclusion: The results showed that patients with panic disorder had higher autonomic arousal than the control group, but the physiologic flexibility was variable. We suggest that it is helpful for treatment of panic disorder to decrease the level of autonomic arousal and to recover the physiologic flexibility in certain stressful event.
