Purpose: This study was carried out to provide the basic information for developing intervention programs for volunteers by identifying the burdens felt by hospice volunteers and the factors related to such burdens. Methods: The subjects were 243 hospice volunteers at 8 hospitals of The Catholic University of Korea. A questionnaire was carried out: 25 questions about the burdens to the participants and 47 questions about the quality of life. The data obtained was analyzed using the SAS program to conduct t-test, ANOVA, Duncan test, and Pearson's correlation coefficient test. Results: 1. The mean total score of the burdens felt by the hospice volunteers was $53.3{\pm}10.4$. There was no significant difference in the level of burden depending on the demographic characteristics of the hospice volunteers. But the burden in care of high education and low quality of life increased significantly. 2. The level of burden to the hospice volunteers decreased significantly as their families more favored their volunteer activities. The subjects felt the highest burden in: family care, physical care spiritual care, emotional care, and after-death care, in this order. 3. The level of burden related to each factors was high in the burden due to patient care, sense of achievement, and volunteer activities, in this order. 4. There was a reverse correlation between the level of burden to hospice volunteers and their quality of life. Conclusion: In order to reduce the burdens to hospice volunteers and to help them tate care of patients more effectively, it would be necessary to provide the education programs about practical patient care problems and to develop measures for improving their quality of life, taking into account their level of education, family's support, and difficulties in their volunteer activities.

The purpose of this thesis is to find the guiding direction of mathematical communication in lower grade students of elementary school and to present a new direction about the effect of using concrete material in communication. It is expected that mathematical communication increases when concrete material is used for the students of the lower grades, who are in concrete operational period. Therefore, this study ai s to investigate what characteristics there are in mathematical communication of second grade students and what effect concrete materials have on mathematical communication and learning. The analysis of the teaching record shows that the second grade students use alternative terms in the process of communication since they are not familiar with mathematical symbols or terms, which is a characteristic of communication in a mathematics class in which concrete material is used. In the process of teaming the students apply their living experiences to their teaming. Since a small number of students lead class, the interaction between students is also led by them. The direction of communication in a small group is not centered around solution of a problem, and most students show a more interest in finding answers than in the process of learning. The effect that concrete material has on communication plays an important role in promoting students' speaking activity; it allows students to identify and correct their errors more easily. It also makes students' activities more predictable, and it increases a small group activities through the medium of concrete material. However, it was also noticed that students' listening activities are not appropriately developed since they do not pay attention to a teacher who uses concrete material. The effects that concrete material has on mathematics class can be summarized as follows. Concrete material promotes students' participation in class by triggering their interest of learning of mathematics and helps them to understand the course of learning. It also helps the teaming and formation of concepts for children of low academic performance. And it makes a phased learning possible according to students' ability to use concrete material and to solve a problem. Based upon the results above mentioned, the use of concrete material is absolutely needed in mathematics classes of lower grade elementary school students since it increases communication and gives much influence on mathematics learning. Therefore, teachers need to develop teaching or learning method which can help increase communication, considering the characteristics of students' communication.
Purpose: Bone mineral densitometry test region advised by ISCD (International Society for Clinical Densitometry) is both site in case of femur, whereas our medical center measures left femur except for few extraordinary cases. It is said that right-handers had higher mean femur BMD in the left side than in the right side, but the factor influence the femur BMD is unknown. Thus, we investigate whether testing left femur only is a adequate clinical diagnosis. Materials and Methods: Subjects were 209 right-handers and 20 left-handers patient in Asan Medical Center from July to August, 30 to 70 years of age ($51{\pm}6.7$). Subjects fill out the questionnaire on hand preference and taking regular exercise. Total BMDs of bilateral femur were measured with GE Lunar Prodigy advance densitometer, and the statistical soft ware SPSS 12.0 for windows was used for statistical analysis. Results: In the total sample of the exercise group (n=127), the difference of both femur mean BMDs are $0.001{\pm}0.127\;g/cm^2$ and the non-exercise group's (n=102) both femur difference is $0.002{\pm}0.126\;g/cm^2$, there is no significant difference. And in exercise group, classified according to hand preference, each t-value is shown at right handers (n=114) are 0.65, left handers (n=13) are -0.39. Also, In non-exercise group, right handers (n=95) are -0.78, left handers (n=7) are -0.64. In the 95% confidence limit, there was no statistically significant difference (p>0.05). Conclusions: In recently researchs, there have been differences between both femurs according to hand preference. However, Our study have no significant difference both femurs BMDs. Therefore we suggest that BMD measurement of femur has no problem only one side, except for particular case like femur operation.

Purpose : Enterobiasis is probably one of the most common parasitic infection world-wide. Human is the only known host of Enterobius vermicularis. Children are more commonly infected with Enterobius vermicularis than adults and infections are commonly recurred. In Korea, there is a high prevalence. So, we performed this study to evaluate the present status of Enterobius vermicularis infection among children in the Masan, Changwon areas and to determine the efficacy of flubendazole against this parasitic nematode. Methods : From November to December, 1997, urban and rural elementary school children and urban preschool children were examined for the presence of Enterobius vermicularis egg. All the children were examined once by an adhesive cellotape anal swab technique in the early morning at home by their parents guided by specific instructions for the technique. Results : 1) A total of 644 adhesive cellotape anal swab specimens was collected from 205 urban elementary school children, 290 rural elementary school children and 145 urban preschool children. Among them, 114(17.7%) were positive for Enterobius vermicularis eggs. There was no significant differences in the rate with regard to sex. 2) In the preschool children, the egg detection rate was 42(29.0%) out of 145 children. This rate was significantly higher compared with 72(14.4%) of 499 school children. 3) The egg detection rates in the rural and urban school children were 15.2, 13.7% respectively. There was no significant difference in both groups. In the 3rd grade and below in elementary school children, there was a higher rate compared with above 4th grade group. 4) In day care center where egg detection rate was high as 41%, the children were given two doses of 100mg flubendazole every 3 weeks, including staffs and family members. After treatment, egg detection rate fatted as 6%. Conclusion : Our data demonstrated that there was high prevalence of Enterobius vermicularis infection. In the light of these results, it is necessary to examine and treat children as soon as possible.
To determine the causes of and related factors to childhood injuries, the emergency room records and inpatient medical records were reviewed for 4,849 injured children out of 15,790 pediatric patients(<15 years old) who visited the emergency rooms of 3 university hospitals and 2 general hospitals in Taegu from 1 January to 31 December 1987. Out of total injured children, 54.675 were 3-8 years old and the male to female ratio of the total injured children was about 2:1. The leading causes of injury were falls and slips (29.1%) and traffic accident(28.2%). The frequency of injury was higher in May-October than the rest of months and 51.6% of the injuries occurred between 15 and 20 o'clock. Falls and slips took place most frequently at the stairway(25.7%). The most common interpersonal violence was inflicted injuries(85.6%) and there were 11 child rapes. Dog bites accounted for 67.6% of all biting injuries and it occured 2.9 times more in male than in female. CO intoxication was the most common cause of poisoning (45.3%) and scalding accounted for 85.2% of all burns. Common places of drownings were river (32.2%), swimming pool (22.6%) and construction site(19.3%). To prevent childhood injuries, it is recommended to eliminate the hazardous environmental factors, to provide safe playgrounds, to educate the children for safety from kindergarten and the general public through mass communication, to establish a strict safety standard for houses, public buildings and facilities, and playgrounds.
To distinguish the anthropogenic inputs from the chemical weathering with water-rock interaction on the chemical compositons of groundwater in Kwangju city, four different water groups were established based on the landuse type, lithology and topology. The sample from greenbelt area belongs to Group Ⅰ, whereas those from green buffer zone, urban area and industrial area belong to Group II, Group Ⅲ and Group Ⅳ, respectively. The geology of this city mainly consists of biotite granite and granitic gneiss. The concentration of main cations is subject to the behavior of feldspars, micas and carbonate minerals. Cl$\^$-/ and NO$_3$$\^$-/ are supplied by anthropogenic inputs such as domestic sewage whose concentration of these anions is highest in the Group Ⅲ samples. With the Piper diagram, the groundwaters of Group Ⅲ are mainly plotted in CaSO$_4$-CaCl$_2$ type, whereas those of other groups are plotted in Ca(HCO$_3$)$_2$ type, The calculation for the activities of ions and saturation indices of some minerals shows that most of the minerals are undersaturated and plotted in the area of equlibrium with kaolinite. Three factors were extracted from the factor analysis for chemical data. Factor 1 controlled by HCO$_3$$\^$-/, Ca$\^$2-/, SO$_4$$\^$2-/, Mg$\^$2+/ and Na$\^$+/, explains the dissolution of carbonate minerals. mica and plagioclase. Factor 2, controlled by Cl$\^$-/ and NO$_3$$\^$-/, explains the influence of artificial pollution. Factor 3, controlled by Mn, Fe and Zn is subject to the industrial waste water, but the evidence is not clear. Factor 1 is dominant in the Group I and II, indicating that those samples are subjected to natural chemical weathering, The higher scores of factor 2 in the Group Ⅲ samples indicate the potential artificial pollution.

Survey was carried out in paddy fields to investigate the dominance of weed species and weed occurrence on 200 fields of southern Gyeonggi region in Korea during the year 2013. We observed 3 species of grass, 5 species of sedge, and 11 species of broadleaf and other weeds. The most dominant weed species was Eleocharis kuroguwai, followed by Echinochloa crus-galli, Sagittaria trifolia, Monochoria vaginalis, Scirpus juncoides and Bidens tripartita. The dominance value of E. kuroguwai and B. tripartita decreased compared to the survey results performed in 2005 but that of M. vaginalis, S. juncoides, S. trifolia and E. crus-galli increased. Weed occurrence increased from 2.83 g in 2005 to 3.51 g in 2013 based on weed dry weight per $m^2$. Occurrence ratio of annual weeds to perennial weeds changed from 45.2% : 54.8% in 2005 to 45.8% : 54.2% in 2013. If we analyze dominance of weed species based on the rice transplanting timing, E. kuroguwai and E. crus-galli were the most dominant weed species at mid-May transplanting, and M. vaginalis and S. juncoides were the most dominant weed species at late- May transplanting, and M. vaginalis and E. kuroguwai were the most dominant weed species at early-June transplanting. Since paddy weeds resistant to sulfonylurea herbicides are expected to be continuously increased, the regular monitoring of their occurrence and efficient control methods should be considered in future.
Family meals are very important for physical and mental health of family mebers. The purpose of this study is to contribute to change the habitual and unconscious cooking methods of housewives into more scientific moth(Ids. In order to achieve this purpose, this study tried to find out the degree to which housewives applied their knowledge of nutition and foods to actual behavior in purchasing. A special form of questionaire was prepared and distributed to 502 housewives in Seoul from Feb.8th to 22nd in 1989. The results were as follows: 1. Mean (score) of their nutritional knowledge was 14 7; if seems to be comparatively higher. 2. When they purchased food materials, their husbands' favor was the first consideration. Particularly, freshness was the first considered in purchasing meat, fishes, fruits, and vegetables. And Nutrition was so in case of seaweeds, oil, and fat. 3. For the most part, they cook three or four Subsidiary dishes for a meal. If they cooked one or two they chose to cook vegetables. If three or four they added meat and fishes. If more than four, they used various food materials.

Objectives: We studied to find out the relevant relationship between the type of residence and the level of mental depression among aged people. Methods: The authors surveyed 156 people who are over 65 in a small city. Here are three groups: 50 persons who live in the facility for the aged. 72 persons who live with their family and 34 persons who live alone. We developed the questionnaire and the severity of depressive symptoms was measured using Korean Form of Geriatric Depression Scale (KGDS) score. Results: Positive rate of depressive disorders among the aged people was 43.6%. Positive rate of depressive disorders among the aged who live in the facility for the aged was 42.0% and that persons who live with their family was 9.7%. It's more likely to be their gender, the marital status, schooling, going out and pocket money that affect on their mental depression. According to the multiple logistic regression, the odds ratios of the persons who live in the facility for the aged versus persons who live with their family and pocket money in a month were significant (p<0.05). Conclusions: The research shows that the mental depression in the aged people is more serious in the facility for the aged and also significantly related to their pocket money.

=Objectives: This study was conducted to evaluate the diferences in Farmer's syndrome between greenhouse-melon farmers and rice farmers. Methods: The study included 160 residents, who lived in rural community. Of those subjects, 73 and 87 from June 1 to July 30, 2006. Respondents were interviewed by means of a structured questionnaire. Results: This study showed that greenhouse-melon farmers had a lower average age, shorter experience of farming, more working hours per day than rice farmers (p<0.05). n farmers was 38.4% respectively, the prevalence in rice farmers was 22.6%. There was statistically significant diference in the prevalence of Farmer's syndrome between greenhouse-melon and rice farmers (p<0.05). The most frequent symptoms among eight symptoms that constitute the Farmer's syndrome were lumbago, shoulder pain and nocturnal urination regardless of type of farming. But greenhouse-melon farmers had higher prevalence of muskuloskeletal symptoms, such as lumbago and shoulder pain, than rice farmers (p<0.05).Conclusions: These results showed that prevalence of Farmer's syndrome was more common in the tools which reduce physical burden and take a rest and exercise periodically during work in the greenhouse-melon farmers.
