  • During the growing season from June to August, 2000, the soil NO and $N_2$O fluxes were measured to elucidate characteristics of soil nitrogen emissions from different types of intensively managed agricultural soils at outskirts of Kunsan City, located in the western inland of Korea, Flux measurements were made using a closed chamber technique at two different agricultural fields; one was made from upland field, and the other from rice paddy field. The flux data from upland field were collected for both the green onion and soybean field. Concentrations of NO and $N_2$O inside a flux chamber ar 15 minute sampling interval were measured to determine their soil emissions. Either polyethylene syringes of teflon air bags were used for gas samples of $N_2$O and NO. The analysis of NO and $N_2$O was made using a chemiluminesence NO analyzer and GC-ECD, respectively no later than few hours after sample collection at laboratory. The gas fluxes were varied more than one standard deviation around their means. Relatively high soil gas emissions occurred in the aftermoon for both NO and $N_2$O. A sub-peak for $N_2$O emission was observed in the morning period, but not in the case of NO. NO emissions from rice paddy field were much less than those from upland site. It seems that water layer over the rice paddy field prevents gases from escaping from the soil surface covered with were during the irrigation and acts as a sink of these gases. The NO fluxes resulted from these field experiments were compared to those from grass soil and they were found to be much higher. Diurnal and daily variations of NO and $N_2$O emission were discussed and correlated with the effects of nitrogen fertilizer application on the increase of the level of soil nitrogen availability.

  • This study was conducted 1) to compare the nutrient content and mineral composition of the Philoppine indigenous sheep and goats diets when grazed in common pasture during rainy season, 2) to determine the influence of sampling methods on nutrient content and mineral composition of upland (UP) and lowland (LP) native pastures, and 3) to compare these two pasture types in terms of nutrient and mineral composition. Experiment 1 used sis esophageally fistulated animals, three each for sheep and goats. Weekly extrusa collection was done for a period of three months. Experiment 2 was conducted in UP and LP; these were sampled thrice by three methods, plucking, clipping and use of three esophageally fistulated sheep. Results of Experiment 1 indicated that the diets of sheep were greater in crude protein(CP; p < 0.01) and ether extract(EE; p < 0.05) but lower in crude fiber (CF) and acid detergent lignin (ADL; p < 0.05) than that of goat diets. All other nutrient fractions including mineral composition were not significantly different from each other. Significant findings of Experiment 2 were: CP content of UP was in the order fistulated > plucked > clipped (p < 0.05); CP content of LP was greater (p <0 .05) in fistulated and plucked samples; and ash content was greater (p < 0.05) in fistulated samples of both pastures. The CP of UP was different (p < 0.05) from each sampling method but the CP of LP and ADL of both pastures were greater (p < 0.05) in clipped samples. Most minerals either macro or microminerals were greater in fistulated samples of both pastures. Pooled data of the two pastures showed that LP had better nutrient characteristics and greater mineral composition. Based from this study, there were few differences between the diets of indigenous sheep and goats when grazed in common pasture. Also, sampling methods influenced the nutrient composition of indigenous sheep diets.

  • Background: The study was conducted to investigate the current status of the occupational health and safety management system (OHSMS) in the construction industry and the effect of OHSMS on accident rates. Differences of awareness levels on safety issues among site general managers and occupational health and safety (OHS) managers are identified through surveys. Methods: The accident rates for the OHSMS-certified construction companies from 2006 to 2011, when the construction OHSMS became widely available, were analyzed to understand the effect of OHSMS on the work-related injury rates in the construction industry. The Korea Occupational Safety and Health Agency 18001 is the certification to these companies performing OHSMS in South Korea. The questionnaire was created to analyze the differences of OHSMS awareness between site general managers and OHS managers of construction companies. Results: The implementation of OHSMS among the top 100 construction companies in South Korea shows that the accident rate decreased by 67% and the fatal accident rate decreased by 10.3% during the period from 2006 to 2011. The survey in this study shows different OHSMS awareness levels between site general managers and OHS managers. The differences were motivation for developing OHSMS, external support needed for implementing OHSMS, problems and effectiveness of implementing OHSMS. Conclusion: Both work-related accident and fatal accident rates were found to be significantly reduced by implementing OHSMS in this study. The differences of OHSMS awareness between site general managers and OHS managers were identified through a survey. The effect of these differences on safety and other benefits warrants further research with proper data collection.

  • Background: In the adjuvant treatment of breast cancer, anthracycline and taxane based regimens can be used concomitantly or sequentially. The best order in the sequential regimens has yet to be well established. This study evaluated the feasibility of 4 cycles of adjuvant taxotere ($100mg/m^2$) every 3 weeks followed by 4 cycles of doxorubicin ($60mg/m^2$) and cyclophosphamide ($600mg/m^2$) every 3 weeks. The primary outcome was the safety profile. Secondary outcomes were disease free survival (DFS) and overall survival (OS). Materials and Methods: This non-randomize prospective phase II stud was performed at Jordan University of Science and Technology and its affiliated King Abdulla Teaching Hospital between July 2009 and August 2010. Data collection was closed on May $31^{th}$, 2015 giving a median follow up period of 62 months. The study was approved by the institutional review board and a written informed consent was obtained for each patient. Results: Fifty patients were enrolled. The median age was 53.1 years (range 34-76). One patient (2%) had stage I disease, 17 (34%) stage II, and 32 (64.0%) stage III. Forty-six patients were evaluable for efficacy analysis. The completion rate was 95.7%. No dose modifications were needed. The incidences of grade 3-4 neutropenia and febrile neutropenia were 14 % and 10%. No grade 3-4 non-hematological adverse events were encountered. At a median follow up time of 62 months the OS and the DFS rates were 76.1% and 56.5%. Those for stages I and II combined were 100% and 75%. Conclusions: Taxotere first followed by doxorubicin-cyclophosphamide appears a feasible regimen as evidenced by an acceptable completion rate, a satisfactory safety profile, and an OS and DFS rates comparable to other studies.

  • This study was cross sectional descriptive survey study to analysis the relationship between marriage value view and health promotion behavior among university students. Questionnaires from those who voluntary agreed to the study were collected online, and the collection period was from May 20, 2020 to June 10, 2020. Research tools for analyzing marriage value view was used by RR lee, and health promotion behavior research tools was developed by Walker., The data analysis was performed using SPSS 18.0 as frequency, Pearson correlation, t-test, and Multiple regression analysis. According to the analysis, women had high passive (p<0.05) and exclusive (p<0.01) marriage value view, while men had high active (p<0.01) and instrumental (p<0.05) marriage value view. According to the analysis, it turns out that people who value interpersonal relationships during health promotion have a positive effect on romantic (t=2.383, R2=.257, p=.019) and instrumental (t=2.201, R2=.120, p=.030) marriage value view. Hygiene has been appeared to affect Passive marriage value view (t=3.001, R2=.111, p=.003) and Exclusive marriage value view (t=3.765, R2=.122, p=.000). Nutrition has been appeared to affect conservative marriage value view (t=2.086, R2=.118, p=0.039). Exercise has been appeared to affect conservative marriage value view (t=2.456, R2=.118, p=0.015) and active marriage value view (t=2.261, R2=.168, p=0.025). Through this study, in order to increase for the desire of marriage, marriage values need to be organized differently between men and women in marriage value programs and it suggested that health promotion behavior be included in programs that enhance the value of marriage.

  • Purpose: The purpose of this study was to examine the effect of maximal sterile barrier precaution on the central venous catheter-related infection and subsequent cost savings. Methods: Study subjects were 462 hospitalized patients with central venous, catheter of more than 48 hours duration. Data collection period was from April 2008 to February 2009 at a tertiary university hospital in Seoul. Subjects were randomly assigned to either the treatment or the usual care group. Patients in the treatment group (n=209) were treated by staff using maximal sterile barrier precautions and the comparison group(n=253) received traditional care. Results: Central venous catheter-days was2,821 in treatment group and 3,515 in comparison group. The incidence density of central venous catheter-related infection was 2.1 times higher in the comparison group (8.2 per 1,000 catheter-days) compared with the treatment group (3.9 per 1,000 catheter-days). The incidence density of central venous catheter-related bloodstream infection was 4.54 times higher than in the comparison group (3.2 per 1,000 catheter-days) compared with the treatment group (0.7 per 1,000 catheter-days). The attributable cost of central venous catheter-related infection in the treatment group was 10,174,197 won and that of the comparison group was 22,224,554 won. Attributable cost by area was also significantly lower compared with that of the comparisons. Conclusion: The maximal sterile barrier precaution during central venous catheter insertion was an effective intervention to reduce central venous catheter-related infection rate and provides a significant cost savings.

  • Background: With the recent rapid industrialization, occupational safety and health (OSH) has become an important issue in all industrial and human activities. However, incidents of injuries and fatality rates in the Ghanaian industry sector continue to increase. Despite this increase, there is no evidence regarding the element of OSH management in transport activities in Ghanaian industries. Thus, this study aims to examine the perceptions regarding the importance of safety and health in work-related transport activities in Ghanaian industries. Methods: A survey data collection technique was used to gather information on best safety practices over a 5-month period. We randomly selected 298 respondents from industries to answer structured questionnaires. The respondents included drivers, transport managers, and safety engineers. Standard multiple regression model and Pearson product-movement correlation were used to performed the analysis. Results: The result shows that for interventions to improve safety and health, concentration has been on drivers' safety practice with less attention to safe driving environments and vehicle usage. Additionally, the respondents are aware of the importance of OSH in transport activities, but the level of integration does not measure up to the standard to reduce operational accidents and injuries. Finally, strong commitment to changing unsafe practices at all levels of operations appears to be the effective way to improve safety situations. Conclusion: OSH culture is not fully complied in industries transport activities. This study, therefore, supports the use of safety seminars and training sessions for industry workers responsible for transport operations for better integration of safety standards.

  • The purpose of this study is to find out the need for sex education of middle school students and their parents. For the data collection, the survey was conducted during the period from September 10 to September 20, 1989 by using prepared questionnaire. A questionnaire was given to 592 students of 1st, 2nd and 3rd grade from four middle schools and to 408 their parents in Suwon City. The major results are summarized as follow; 1. Among the 25 questions were asked about knowledge of sex, the structure of reproductive organs, physical change during puberty, menstruation, Sexually stimulation and family plan were answered correctly by over 50% of the students. The higher the grade, the more the knowledge of sex. There was no significant difference between this knowledge and with eider sister or brother. Among the 20 questions were asked about knowledge of sex, sexually stimulation, pregnancy, emission, induced abortion and sexually transmitted disease were answered correctly by over 50% of the parents. 2. 30 questions were asked about attitude of sex, 47.7% of the students and 53.4% of the parents answered 'positive'. There was no significant difference between grade and sex of students. A significant difference '.vas not also found between years and education level of parents. 3. In case of students, experience of sex education was showed the structure of reproductive organs, physical change during puberty, temper during puberty, menstruation, emission more. In the event of parents, experience of sex education was showed the structure of reproductive organs, temper during puberty, menstruation, emission, relationship with apposite sex more. Most students felt that sex education should begin from the first grade of middle school and the first grade of high school strongly. In parents was showed the need for sex education from the primary school and the first grade of middle school highly. Namely, students and parents felt that sex education should begin from puberty. To help good developments and growth of middle school students with rapid change should be educated sex eduction properly for the occasion.
