This study was conducted to assess the attitude of pregnant women toward delivery method, understanding of the reason for determining her own delivery method, participation in decision-making process and satisfaction with delivery method after labor. Study subjects were 693 pregnant women who had visited obstetric clinic for prenatal care in the last month of pregnancy in one general hospital and one obstetrics-gynecology specialty hospital in Taegu city from February 1 to March 31 in 1998. A questionnaire was administered before and after labor and a telephone interview was done one month after labor. Proportion of women who had health education and/or counselling about delivery method during prenatal care was 24.0% and this proportion was higher for women who had previous c-section(35.5%) than others. Women thought vaginal delivery is better than c-section for both maternal and baby's health regardless of previous delivery method. About 90% of primipara and multiparous women who had previous vaginal delivery wanted vaginal delivery for the index birth, while 85.6% of multiparous women who had previous c-section wanted repeat c-section. Reasons for choosing c-section in pregnant women who preferred vaginal delivery before labor were recommendation of doctors(81.9%), recommendation of husband (0.8%), agreement between doctor and pregnant woman(4.7%), and mother's demand (12.6%). Reasons for choosing vaginal delivery were mother's demand(30.6%) and no indication for c-section(67.2%). Reasons for choosing c-section in pregnant women who preferred c-section before labor were recommendation of doctors(76.2%), mother's demand(20.0%), recommendation of husband(1.3%), and agreement between doctor and pregnant woman(2.5%). Of the pregnant women who had c-section, by doctor's recommendation, the proportion of women who had heard detailed explanation about reason for c-section by doctor was 55.1%. Mother's statement about the reason for c-section was consistent with the medical record in 75.9% . However, over 5% points disparities were shown between mother's statement and medical record in cases of the repeat c-section and mother's demand. In primipara and multiparous women who had previous vaginal delivery, the delivery method for index birth had statistically significant association with the preference of delivery method before labor(p<0.05). All of the women who had previous c-section had delivered the index baby by c-section. Among mothers who had delivered the index baby vaginally, 84.9% of them were satisfied with their delivery method immediately after labor and 85.1% at 1 month after labor. However, mothers who had c-section stated that they are satisfied with c-section in 44.6% immediately after labor and 42.0% at 1 month after labor. Preferred delivery method for the next birth had statistically significant association with delivery method for the index birth both immediately after labor and in 1 month after labor. The proportion of mothers who prefer vaginal delivery for the next birth increased with the degree of satisfaction with the vaginal delivery for the index birth but the proportion of mothers who prefer c-section for the next birth was high and they did not change significantly with the degree of satisfaction with the c-section for the index birth. These results suggest that the current high technology-based, physician-centered prenatal and partritional cares need to be reoriented to the basic preventive and promotive technology-based, and mother-fetus-centered care. It is also suggested that active involvement of pregnant woman in decision-making process for the delivery method will increase the rate of vaginal birth after c-section and decrease c-section rate and improve the degree of maternal satisfaction after delivery.

This survey was conducted on a total 672 pulmonary tuberculosis patients who were registered at certain health center in Busan, during the period from July 15th to August 31st, 1977, based on Modified Cornell Medical Index(CMI) consisting of 70 questions. Number of 'Yes' response of an individual patients was collected by each large section of Modified CMI. The each number of 'Yes' response was standardized by mean of Z scoring. Z score was obtained by following formula. Z=50+10(Xi-m)/s M : means of 'Yes' response by each section for all subjects s : standard deviation of the mean Xi : number of 'Yes' response by each section in an individual patients The results of obtained were as follows: 1. The number of investigated cases were 672 (459 males and 213 females). The most prevalent group was 20-24 years old group as 18.4% by age, moderate advanced group as 50.8% by radiological diagnosis, INH+PAS+SM group as 34.7% by antituberculotics and unemployed group as 59.9% by occupation. By bacteriological examination of sputum, the rate of negative group was 60.5% and positive group was 39.5%. 2. Z score of complaints by sex was higher in female as 52.4 than in male as 48.9 in general. By radiological diagnosis, there was decreasing tendency with age in male but increasing tendency with age in female. 3. By age group, Z score of complaints was increasing tendency with age in male but there was non-significant differences in female. 4. By bacteriological examination of sputum, the Z score of complaints was increasing tendency with the more discharged bacteria in both sex generally. 5. By antituberculotics, INH group was revealed the highest Z score of complaints as 50.4 in male and INH+PAS group was the highest as 51.21 in female. 6. By occupation, agricultural and fisherman group was the highest as 53.5 and the next group was professional, technical and related workers, unemployed and sales workers in that order.

Objectives: In this study, we started to develop an indoor garden integrated IoT solution based on IAQ (indoor air quality) and interconnection with an environmental database for smart management of indoor gardens. The purpose of this study was to develop and apply an integrated solution for customized air purification from an indoor garden through big data analysis using IoT technology. Methods: An IoT-based IAQ monitoring system was established in three households within a new apartment building. Based on real-time and long-term data collected, $PM_{2.5}$, $CO_2$, temperature, and humidity changes were compared to those of indoor garden applications and the analyzed results were indexed. Results As a result of the installation, all three households had no results exceeding the standard for indoor air pollution on average $PM_{2.5}$ and $CO_2$ indices. In the case of indoor garden installation, the IAQ index increased to the "Good" section after the installation, and readings in the "Bad" section shown before the installation disappeared. The comfort index also did not dip into the "Uncomfortable" section, where it had been preinstallation, and significantly lowered the average score from "Uncomfortable for sensitive groups" to "Good". Overall, the IAQ composite index for the generation of installations decreased the "Good" interval, but "Bad" did not appear. Conclusions In this study on developing an integrated solution for IAQ based on IoT indoor gardens, big data was analyzed to determine IAQ and comfort indexes and an IAQ composite index. Through this process, it became understood that it is necessary to monitor IAQ based on IoT.

The purpose of this study was to investigate the differences of middle school students' recognition of food and nutrition part in Home Economics by gender, school location and school type. The study was carried out through questionnaire about three category: perception (interests, practical usefulness, attitude change in food behavior), difficulty (nutrition and health in adolescence, balanced diet, principle of cooking and preparing food), necessity (nutrition and health in adolescence, balanced diet, principle of cooking and preparing food). The subjects were 1014 middle school students of 1st grade in Jeonbuk area; urban 334, suburban 339 and rural 341. The results of this study were as follows. 1) There was difference in ‘interests’ by gender (girls > boys), school location (urban, suburban > rural) and school type (coeducation > boys, girls). There were differences in ‘practical usefulness’ by school location (urban > rural) and in ‘attitude change in food behavior’ by school location (urban > suburban > rural) and school type (boys, girls > coeducation). 2) There was difference in difficulty in section of ‘nutrition and health in adolescence’ by school location (suburban > rural). There were no differences in section of ‘balanced diet’ by gender, school location and school type. But there were differences in section of ‘ principle of cooking and preparing food’ by school location (urban, rural > suburban) and school type (coeducation > boys). 3) There were differences in necessity for ‘balanced diet’ and for ‘ principle of cooking and preparing food’ by school location (urban, suburban > rural) and school type (coeducation > boys, girls). Characteristically, the boys had more necessity for ‘nutrition and health in adolescence’ and for ‘balanced diet’ than girls but girls had more necessity for ‘principle of cooking and preparing food’ than boys. It suggests that gender, school type and school location should be considered for an effective and practical curriculum of food and nutrition part in Home Economics.

The aims of this study were to assess whether Indonesian women with breast cancer havea higher external health locus of control (HLC) than healthy women, and to explore the association between HLC and symptoms of anxiety and depression. In this study, 120 consecutive women with breast cancer were recruited at the outpatient surgical oncology clinic at the Hasan Sadikin Hospital in Bandung. One hundred and twenty two healthy women were recruited from the Bandung area as controls. A standard demographic form, Form C of the Multidimensional Health Locus of Control, as well as the Hospital Anxiety and Depression Scale and patients' medical records were used. Data were analyzed using descriptive statistics, t-test, Pearson's correlation, MANOVA and multiple linear regressions. Women with breast cancer had higher scores on all external HLC subscales, i.e. chance, doctor, powerful others and God, and lower internal HLC compared to healthy women. High God LHC scores were associated with a high level of anxiety (${\beta}=0.21$, p<0.05), whereas none of the HLC subscales were associated with depression. Our results suggest that women with breast cancer tend to have high external HLC, while healthy women tend to have high internal HLC. A strong belief in an external source of control, i.e. God, might be negatively associated with patient emotional adjustment. Further research is needed to give an insight into the direction of this association.

Background: We aimed to evaluate the role of genetic polymorphisms in tobacco carcinogen-metabolizing genes and their interactions with smoking in a hospital-based case-control study of Japanese subjects. Materials and Methods: We examine the associations of pancreatic cancer risk with genetic polymorphisms in GSTM1, GSTT1 and GSTP1, phase II enzymes that catalyze the conjugation of toxic and carcinogenic electrophilic molecules. The study population consisted of 360 patients and 400 control subjects, who were recruited from several medical facilities in Japan. Unconditional logistic regression methods were used to estimate odds ratios (ORs) and 95% confidence intervals (CIs) for the associations between genotypes and pancreatic cancer risk. Results: Among the control subjects, the prevalence of the GSTM1-null genotype and the GSTT1-null genotype was approximately 56% and 48%, respectively. Cases and controls were comparable in terms of GSTM1 and GSTT1 genotype distributions. Neither of the deleted polymorphisms in GSTM1 and GSTT1 was associated with the risk of pancreatic cancer, with an age- and sex-adjusted OR of 0.99 (95%CI: 0.74-1.32) for the GSTM1-null genotype, and 0.98 (95%CI: 0.73-1.31) for the GSTT1-null genotype. The OR was 0.97 (95%CI: 0.64-1.47) for individuals with the GSTM1 and GSTT1-null genotypes compared with those with the GSTM1 and GSTT1- present genotypes. No synergistic effects of smoking or GST genotypes were observed. Conclusions: Our results indicate no overall association between the GSTM1 and GSTT1 deletion polymorphisms and pancreatic cancer risk in the Japanese subjects in our study.

By evaluating the health status of 152 male workers engaged in a metal-product factory by Cornell Medical Index in conjunction with their experience of industrial accident, I attempted to find out whether any health condition may effect on the occurence of industrial accident. Differences in frequency of complaints in each section of CMI between control workers and accident workers were statistically tested by T-test. On the other hand, influence of neuropsychiatric factors (section M-R) on the occurence of accidents was analyzed by $X^2-test$ with Fukamachi's classification. The followings were the results obtained in this study. 1. The average number (26.42) of physical complaints in accident group is significantly more than in control group (18.70). 2. The average number (17.70) of mental complaints in accident group is very significantly more than in control group (11.70). 3. Differences in frequencies of complaints by sections between accident group and control group was all significant except C (cardiovascular system), H (genitourinary system), I (fatigue) & J (frequency of disease). 4. frequency rate of neurotic workers who were identified by Fukamachi's classification was significantly higher in accident group (72%) than in control group (51%).

Purpose: The purpose of this study was to compare birth outcomes between Korean women and immigrant women. Methods: Medical records were reviewed retrospectively from 201 immigrant women and 201 Korean women who delivered babies at K women's hospital in U city from January 2006 to December 2009. Maternal outcomes related factors included nationality, age, obstetric history, delivery type, indications of cesarean section, and complications of pregnancy and delivery. Principal neonatal outcomes were birth weight, Apgar scores, and complications of newborns. Results: Immigrant women were younger and had fewer pregnancies, abortions, and surviving children than Korean women. The rate of primary cesarean section and its indication in immigrant women were not significantly different from Korean women. However, immigrant women's newborn were more likely to have low birth weight and meconium staining. Conclusion: The results of this study indicate less equity of immigrant women in women's health care, although immigrant women's babies had lower Apgar score and more meconium staining. Nurses should help immigrant women cope with labor process effectively to prevent adverse health outcomes for their newborns.

Purpose: This study was conducted to evaluate desorption efficiency and storage stability on activated carbon acquired form domestic market. Materials: Mixture of acetone, benzene, normal hexane and toluene was injected on four types of charcoal 100 mg. After overnight, charcoal was desorbed by carbon disulfide $1m{\ell}$ and analyzed by gas chromatography with flame ionization detector. Results: Desorption efficiency of benzene, normal hexane and toluene in charcoal tubes were 95% ~ 105%. But desorption efficiency of acetone in charcoal tubes was below 75% and different from types of charcoal. The more injected amount of acetone on charcoal showed higher desorption efficiency. Acetone injected on charcoal tubes migrated from front section into back section after 10 days storage at room temperature. Conclusions: Desorption efficiency and storage stability of activated carbon acquired from domestic market was good for benzene, normal hexane and toluene. The activated carbon acquired from domestic market has ability to be used as sampling media.

Background : 6.1% of red blood cells and whole blood issued to the operating room was not transfused to the patients and discarded in Seoul National University Hospital in 1994. Objectives : We planned to set up an effective management program of blood in the operating room and we investigated whether this program could reduce the disposal rate of blood. Methods : We made a guideline of blood management in the operating room through a workshop. The guideline was revised after a preliminary application. The revised guideline was applied for 5 months from May to September in 1996. The disposal rate was compared before and after the installation of the new program. Results : 5,336 units of blood were issued to the operating room for 5 months. Disposal rate of red blood cells and whole blood was markedly reduced from 6.2% in May to 2.1% in September(p<0.05). The average disposal rate was 3.7% during the five months. Conclusion : We were able to reduce the disposal of unused blood in the operating room through the development and the application of a new blood management program.
