The purpose of this paper was to find out how the economic experiences of college students would affect their economic literacy via a survey with 494 D college students in Daegu city. First, economic literacy based on the general societal characteristics indicates 48.33 with females and 46.76 with males on average respectively, which shows a low score by and large. In the program divisions of college, nursing students showed the highest economic literacy, 58.67, followed by students in humanity and society, 53.56 students in engineering, 49.00 students in public health, 45.78 and students in art and physical education, 39.64. Levels of education of college students' father also affected economic Literacy of college students. College students whose father has a middle school diploma or lower revealed the highest economic literacy, 50.11. A second place is those whose father has a high school diploma, 49.57. The lowest score was recorded by those whose father has a graduate school degree. Even among the college students, those who just graduated from high school exhibited the highest economic literacy, 49.35, whereas those with a graduate school degree showed the lowest, 40.00 on average. In the economic literacy by financial empirical characteristics, college students who answered that they had an experience of opening a bankbook came up with 48.47, and those who answered that they had never opened a bankbook demonstrated a very low score of 30.20 on average. In the economic literacy by economic life variable, college students who never receive pocket money showed the highest score of 50.88, and those who get some pocket money whenever they need exhibited the lowest score of 44.23 on average. In the economic literacy by economic education variable, college students who answered that they had taken an economic education showed a score of 50.09. On the other hand, those who answered that they had never taken an economic education exhibited a score of 45.23 on average. College students who said that economic education is necessary showed a score of 50.24 in the economic literacy, whereas those who said that economic education is not necessary exhibited a score of 45.23 on average.

Purpose: The purpose of this study was to investigate factors associated with sexual debut among Korean middle school students. Methods: From the database of the Eighth Korea Youth Risk Behavior Web-based Survey (KYRBS), the researchers selected 37,297 middle school students aged 12-15 years. Data were analyzed using $x^2$ test and multiple logistic regression with the SPSS WIN 18.0 program. Results: The proportion of middle school students who had a sexual debut was 2.1% of boys and 1.5% of girls. In multiple regression analysis, economic status, experience of part time work, smoking, drug use and depression were associated with an increased proportion of sexual intercourse for both boys and girls. Living with parents, drinking alcohol and suicidal ideation were associated with sexual debut for boys only. By contrast, formal sexual education was associated with a reduced risk of sexual debut. Conclusion: The results of this study show the factors associated with sexual debut among Korean middle school students. Gender-related interventions should be taken into consideration in school sexual education programmes, because of differences in related factors according to gender.

The dark respiration, photosynthesis($CO_2$ refixation), $CO_2$ balance and chlorophyll content of 1st-year conelets and 2nd-year cones of Korean pine(Pinus koraiensis S.et.Z.) were investigated after pollination up to the end of maturation. The results obtained are as follows : 1. The growth of 1st-year conelet was 3.6cm in length. 2.4cm in diameter and 3.058 in dry weighs during the first year. The growth of 2nd-year mature cone was 13.5cm in length, 9.3cm in diameter and 141.0g in dry weight in the late of 2nd-year. 2. The refixation of carbon dioxide released from a cone by the dark respiration was less than 50 percent at light saturation through the growing period. The refixation of carbon dioxide released by dark respiration for one year was 7.3 percent in 1st-year conelets and 8.7 percent in 2nd-year cones. 3. The dark respiration rate of cones by increasing temperature was rapidly increased with increasing temperature up to $25^{\circ}C$. The dark respiration rate of cones was much higher in non-growing season than that in growing season at the same temperature. 4. The rates of dark respiration and $CO_2$ refixation, based on the dry weight, were much higher in 1st-year conelet than that in 2nd-year cone. 5. The $CO_2$ balance for a cone was negative from pollination to the end of maturation. The net dark respiration loss for a cone was 7.23g $CO_2$/year in 1st-year conelet and 164.8g $CO_2$/year in 2nd-year cone. 6. The respiratory loss efficiency for a cone(=$CH_2O$ weight calculated by net dark respiration/dry weight of cone) for one year was 1.61 in 1st-year conelet and 0.81 in 2nd-year cone for one year. 7. The total chlorophyll content of surface scale of the cone was lower than 2mg/g dw through the growing period, and chl. a/b ratio was 2 to 3.

Purpose : Vancomycin-resistant enterococci(VRE) are now nosocomial pathogens in Korea. But little is known about the prevalence of stool colonization with VRE in neonates in Korea. So we studied the prevalence and risk factors of VRE colonization in the Neonatal Intensive Care Unit(NICU). Methods : From January 2000 to December 2004, the medical records of 294 neonates(127 cases of VRE group and 167 cases of non-VRE group, according to the results of stool culture) were reviewed retrospectively. We studied the annual prevalence of VRE and risk factors of VRE colonization in neonates. Results : From 2000 to 2003, the prevalence rate of VRE in NICU increased. After preventing VRE transmission, the prevalence rate of VRE has decreased. Conclusion : VRE colonization increased recently. Risk factors of VRE colonization were prematurity, lower birth weight, longer hospitalization and use of vancomycin or 3rd generation cephalosporin, compared with the non-VRE group. To prevent VRE transmission among newborns, aggressive infection control strategies by NICU staffs must be implemented immediately for all babies.

The changes in contents of chlorophyll and free proline in the seedling leaves of ten rice cultivars as affected by salt stress were checked in order to obtain the basic information on the judgement of the degrees of salt injury. The difference in salt injury among the cultivars was clearly observed about 25 days after 6% salt treatment. Chlorophyll content was decreased in both Gayabyeo and Taebaegbyeo for 14 days after different salt treatment as salt concentration was increased and the decreased tendency was much higher in Taebaegbyeo than in Gayabyeo over 0.4% salt concentration. Chlorophyll content in Gayabyeo after 0.6% salt treatment was decreased slowly, while in Taebaegbyeo, deminished very rapidly as time progressed, therefore it decreased by about 16% in Gayabyeo and 67% in Taebaebyeo compared to the control at 20 days, respectively. The relationship between chlorophyll content and the degrees of salt injury in ten rice cultivars showed significant negative correlation at 10 day after 0.6% salt treatment. Free proline content in Gayabyeo was increased gradually for 14 days after different salt treatment as salt became higher, while in Taebaebyeo, it was increased rapidly under 0.6% but rather decreased under 0.8% salt concentration. Particularly, it was much higher Taebaegbyeo than in Gayabyeo under salt concentration from 0.4 to 0.6%. Free proline content in Gayabyeo after 0.6% salt treatment was increased from 15 days, on the other hand in Taebaegbyeo, it was increased from 5 days, but rather decreased from 20 days, and it was 6 times higher in Taebaegbyeo than in Gayabyeo at 10 days. There was significant positive correlation between free proline content and the degrees of salt injury in ten rice cultivars at 10 days after 0.6% salt treatment. From the above results, chlorophyll and free proline content may be used as an indicative character of intensity of salt stress as well as varietal difference in resistance to salt stress in the seedling stage.

Purpose: The purpose of this study is to provide baseline data for the development of an educational program for hospice care for college students. Methods: A survey was conducted at three universities in B city with 143 students from September 5, 2014 through September 26, 2014. The data were analyzed by the SPSS 18 program. This study was approved by IRB. Results: The college students' spiritual well-being was at a medium level. Their attitudes to death were neutral, and perception of hospice care was at a medium level. Most of the participants (93.0%) had no training in hospice care. The participants' awareness of the purpose of hospice care was at a relatively high level. Their awareness of the need for hospice care was at a moderate level. The participants' spiritual well-being and their attitudes to death showed a weak but positive correlation (r=0.179, P=0.030). The relationship between their spiritual well-being and awareness of hospice care were positively correlated (r=0.203, P=0.015). Conclusion: The participants' perception of hospice care was low. Most of them had no experience of hospice care education. Also, the higher the spiritual stability was, the higher the participants' perception of the purpose and the necessity of hospice care was. And their perception of the hospice care varied depending on their family relationship, satisfaction with school life, and cognition of hospice care. Therefore, we need consider these variables to develop a hospice education program to enhance college students' attitudes to death and their perception of hospice care.

This study investigated temporal changes in forest physical variables and their effects on thermal comfort and physiological and psychological responses. Environmental factors (air temperature, mean radiant temperature, wind speed, and relative humidity), the predicted mean vote (PMV), and the predicted percentage of dissatisfied (PPD) visitors were continuously measured between 9:00 AM and 6:00 PM. We assessed the physiological and psychological responses (heart rate variability, heart rate, oral temperature, blood pressure, pulse rate, thermal sensation vote, comfort sensation vote, and subjective feelings) of 30 male university students (average age: 21.7±1.9 years), who closed their eyes and relaxed for 5 minutes every hour. Examination of correlations between environmental factors and physiological responses showed that ① the mean radiant temperature, wind speed, and relative humidity significantly changed with time; ② PMV and PPD also showed significant changes over time, and the thermal sensation vote corresponded with PMV; however, the comfort sensation vote did not correspond with PPD; ③ Among the physiological responses, parasympathetic nerve activity, sympathetic nerve activity, heart rate, and diastolic blood pressure significantly varied with time, with parasympathetic nerve activity having the lowest value and sympathetic nerve activity the highest at the highest air temperature (2:00-4:00 PM); and ④ Air temperature, mean radiant temperature, and wind speed showed a negative correlation with parasympathetic nerve activity and a positive correlation with sympathetic nerve activity. These findings indicate that the relaxation effects of the forest environment depend on what time of day people are exposed to it, and the changes occurring in forest environmental factors over time modulate these effects.

Background : It is almost important therapy modality to control pain for the terminal cancer patients for the last 24 hours because those terminally illed patient deserved to have pain free and peaceful time before death. Physician who is deal with terminal cancer patients for their last 24 hours does not need to worry about drug addiction or other untoward side reactions of pain medications. The purpose of this study was to evaluate if terminally illed cancer patient was given pain medication properly and sufficiently and if there was any different behavior to control pain of terminal cancer patients between medical physicians and surgeons in terms of type, amount and administration route and frequency. Methods : A retrospective chart audit of analgesic type, amount and administration route was performed on the medical recorders of 160 hospitalized terminal cancer patients who had died in the Korea University Medical Center Anam Hospital during the period of July 1, 1994 to June 30, 1995. Patients were classified into 103 patients were cared for by medical physicians and 57 patients were cared for by surgeons. After then, we analysed the difference of pain control pattern between them. Different types and amount of analgesics were converted to a common standard, an oral morphine equivalents(OME) relative to 1mg of oral morphine. Results : 1) The total number of patients was 160, male 102 cases(63.8%), and the female was 58 cases(36.2%) respectively. 2) The mean age was 56.4(${\pm}14.62$) years old and mean admission period was 27.8 days(${\pm}34.85$). 3) The frequent cancer site was stomach 42 cases(26.315), lung and liver 29 cases(18.1%) each, pancreas 10 cases(6.2%) in order 4) 125 out of 160 subjects (78.13%) complained pain, and 66 out of 103(64.08%) and 31 out of 57(54.39%) were treated with analgesics to relieve pain. 50 out of 97(51.55%) were able to continue on oral medication. 5) 86 cases(53.75%) were well oriented 24 hours prior to death. 6) The frequent analgesics for regular basis were long acting form of oral morphine 34 cases(Medical phsicians 24, Surgeons 10), intravenous morphine 26 cases(Medical physicians 20, Surgeons 6) in order, and the most common p.r.n.(pro re nata) analgesics used was intravenous morphine. 7) The mean amount of analgesics on regular basis was 115.41 OME by medical physicians and 52.7 OME by surseons(P<0.05). The mean amount of p.r.n. analgesics was significantly larger in patients are for by surgeons(66.64 OME) than medical physicians 23.49 OME(P<0.01). 8) The mean frequency of administrated number of p.r.n. analgesics was 0.62 times/day on medical part and 1.88 times/day on surgical part (P<0.001). Conclusion : Of the 97 patients with advanced cancer, 51.55% were able to take oral medications in the last day of life. The parenteral analgesics were more frequently used in the patients cared for by surgeons than medical physicians. Over the half of terminal cancer patients were well oriented in the last day of life. Doctor's knowledge and attitude towards pain is very important to mange the pain, effectively.

A study of the knowledge, attitude and practices about the maternal and child health of 305 married women residing in apartments at the Yonsei Community Health area was conducted during the period from November to December 1970 using designed questionnaire with well trained interviewers. The results and findings obtained from the study are summarized as follows: A. Pregnancy and Birth Questions were asked about their last child. 1. 16.4% of the women were pregnant. 2. Among 281 women who had experienced delivery, 48.0% were assisted by doctor or midwisves for their last delivery, while the rest of women delivered their last baby at home without any professional's assistance. The higher the level of education or the greater exposure to mass communication, the more the deliveries were assisted by doctors or midwives. Those women who were born and raised in cities had more deliveries assisted by doctors and midwives than those who were not. 3. Kinds of delivery sheets used. Among 141 cases of home delivery 68% used cement bag paper or vinyl sheets. Three% used nothing and remained used unsterile materials. 4. Among 141 cases of home delivery, 70.2% used scissors. The rest of them used other methods. 5. 47.3% of the women had a rest for one month or more after birth. The higher the level of education, the longer the period of rest was observed. 6. 52.4% of the women fed the colostrum to their babies. This was not related to the mother's education. 7 About half(42.9%) of the women had poor knowledge about a proper diet for the pre and post natal period. B. Child Health 1. Knowledge and practice regarding to the immunization for their children: Most of the women (93.2%) could name at least one kind of immunization. 20.3% could name 6 kinds of immunization. Mothers education level did not influence their ability to name immunizations. 85.2% of children had been immunized at least once. 2. Morbidity of last born children: 48.1% of their last born children were found to have been sick during the last year. Less than half(41.5%) of the sick children were seen by doctor. 3. Counselling at well baby clinic: Most of the women(76.5%) had no counselling for their children. Registration rate at the well baby clinic at the Severance Hospital was 13.2%. 45.9% wanted to visit to the well baby clinic at the Severance Hospital. 4. Weaning Period: 44.6% said that the beginning of the weaning for their last born children was from 6 months to twelve months of age. The most important reason of weaning was the health of both mothers and children. 5. Knowledge and Practice regarding birth and death Registration: 64.6% of the women could name correctly the Ku-office as the place for the registration. Only 29.2% registered the birth of their last born children within 14 days. C. Knowledge, Attitude and Practice regarding to family planning Most: of the women accepted the idea of family planning. 97.7% could name at least one contraceptive method. 35.4% were found to be current users of contraceptive methods. The ideal number of children was 3.1 in average.
