This study was conducted to investigate the effects of sociocultural attitude toward appearance, social pressure, and stress on university students' body figure discrepancy. A total of 363 students were recruited from a university in C and A city. Data were collected by self-reported questionnaires from Oct 27 to Dec 9, 2016. Statistical analyses of the collected data were conducted using SPSS 20.0 and consisted of descriptive statistics, Pearson's correlation, and multiple regression. A positive relationship was observed between body figure discrepancy and female's sociocultural attitude toward appearance (r=.406, p=.006), peer pressure (r=.197, p<.001), parental pressure (r=.176, p=.002), and stress (r=.218, p<.001). Body figure discrepancies increased with peer pressure (${\beta}=.159$, p=.007), stress (${\beta}=.186$, p=.002), and BMI (${\beta}=.186$, p=.002), and these factors accounted for 10.9% of the body figure discrepancy. To reduce body figure discrepancy, it is necessary to develop health education and promotion programs that enable university students to manage weight and stress for health maintenance and to have positive self-assessment without being hurt by other people's view or evaluation.

Objectives : This study was designed to assess the general distribution, clinical effectiveness of Korean medical treatment on knee pain and the correlation between Korean medical therapy on knee pain and BMI. Methods : This is an observational study. 65 patients admitted to Daejeon Jaseng Hospital of Korean Medicine with musculoskeletal disorders were observed from July, 2014 to July, 2015. They were analyzed according to sex, age, pain lesion, body mass index(BMI) and treatment efficacy. All patients received a combination of treatments during hospitalization, including acupuncture, pharmacopuncture, herbal medicines and physical therapy. A zero to ten numerating rating scale (NRS) assessing pain, Western Ontario and McMaster Universities Arthritis Index(WOMAC) index and Range of Motion(ROM) was used before and after treatments. Statistical correlations among assessment measurements were evaluated by examining the paired t-test and the Pearson's correlation coefficients. Results : The average BMI of all patients was $24.03{\pm}2.95kg/m^2$. According to clinical definition of obesity by Korean Society for the Study of Obesity, 33.8% of all patients was within normal weight, 1.5% was underweight, 33.8% was overweight, 24.6% was obesity and 6.2% was morbid obesity. For knee pain patients, NRS (Numeric Rating Scale) decreased from $6.28{\pm}1.63$ to $3.94{\pm}2.03$(p<0.001). WOMAC index decreased from $48.14{\pm}17.63$ to $40.37{\pm}18.28$(p<0.001). But, there were no significant correlations in statistics among BMI, knee pain index and knee pain index improvement. Conclusions : Korean medical combination treatment might be effective in reducing pain and improving functional disorders for patients with knee pain. This study further confirmed the efficacy of Korean medical treatment on knee pain. But, more studies on correlation between knee pain and obesity and development of assessment measurement are needed.

The aim of this study is to analyze the variations among hospitals and hospital groups in resource use and procedures of diagnostic and therapeutic process, such as laboratory tests, radiologic examinations, tissue diagnosis, timing of surgery after admission, the time required for operation. The study was performed for five procedures including cesarean section (C/S), appendectomy, cholecystectomy, cataract extraction, and pediatric pneumonia. The 2,316 subjects were selected from medical insurance claims list, and from this list 413 cases were sampled for medical record review. The patterns of resource utilization and process of treatment were described according to hospitals and characteristics of hospital groups. The major results were as follows : 1. The numbers of laboratory and radiologic tests showed significant difference among hospitals and hospital groups. In case of hospital groups, we could find tendencies of more tests with increasing hospital bed size. 2. In general, the proportion of operative cases evaluated by tissue diagnosis postoperatively among all operations ranged from 28.3% to 100%. The proportion varied among hospital groups, of which general hospital A group(more than 15 specialty) showed the highest proportion. 3. Post-admission delay until operation and the time required for operative procedure were not invariable among hospitals and hospital groups. The duration of operation in tertiary hospitals was slightly shorter than general hospitals, with varying statistical significance. We could find that probably there were differences of quality among hospitals in some components of procedures, which suggested that the implementation of quality assurance activities would be mandatory. In this study, we simply described the patterns of resource utilization and some features of clinical process, with institution of the need for advanced studies with in-depth analyses for each component of diagnosis and treatment procedures.

In recent years, Ministry of Environment (MOE) has been implementing a phased strengthening of the effluent standards for sewage treatment plants. In this regard, a comprehensive system should be developed to help check the appropriateness of such standards by specifying the grounds for standard-setting and investigating the current operation of sewage treatment plants clearly. It is necessary to establish a new standard-setting system for the effluent that is in a closer connection with the environmental criteria and rating systems. In the United States, the federal government provides guidelines on the least provisions and requirements for the Publicly Owned Treatment Works (POTWs). Local governments set the same or stricter guidelines that reflect the characteristics of each state. In Japan, the sewage treatment plants are subject to both the effluent standards and the discharge acceptable limits to pubic waters under the sewerage law. Specific requirements and limits are set in accordance with local government regulations. The European Union imposes sewage treatment plants with different provisions for effluent standards, depending on the sensitivity of public waters to eutrophication. The effluent standards for sewage treatment plants are classified by pollutant loads discharged to receiving waters. MOE also needs to introduce systems for setting new parameter standards on a POTW effluent by applying statistical means and treatment efficiencies or optimal treatment techniques, as seen in the cases of the US National Pollutant Discharge Elimination System (NPDES) or the EU Integrated Pollution Prevention and Control (IPPC).

This study was to present the proper probability distribution models that based on the data for surveys of food cold storage temperatures as the input variables to the further MRA (Microbial risk assessment). The temperature was measured by directly visiting 7 food plants. The overall mean temperature for food cold storages in the survey was $2.55{\pm}3.55^{\circ}C$, with 2.5% of above $10^{\circ}C$, $-3.2^{\circ}C$ and $14.9^{\circ}C$ as a minimum and maximum. Temperature distributions by space-locations was $0.80{\pm}1.69^{\circ}C$, $0.59{\pm}1.68^{\circ}C$, and $0.65{\pm}1.46^{\circ}C$ as an upper (2.4~4 m), middle (1.5~2.4 m), and lower (0.7~1.5 m), respectively. Probability distributions were also created using @RISK program based on the measured temperature data. Statistical ranking was determined by the goodness of fit (GOF) to determine the proper probability distribution model. This result showed that the LogLogistic (-4.189, 5.9098, 3.2565) distribution models was found to be the most appropriate for relative MRA conduction.

The key objective of this study was to analyze sampling efficiency of various fish sampling gears for a lentic ecosystem health assessment. This survey was conducted at twelve sampling locations of Jinyang Reservoir in November, 2008 and June, 2009. Sampling gears used in the field were fyke net (FN), gill net (GN), trammel net (TN), casting net (CN), minnow trap (MT), and kick net (KN). Fishes sampled in Jinyang Reservoir were 29 species, in which tolerant species, as a proportions of the total numbers, dominated the fish community compared to the sensitive species. Overall sampling indicated that 28 species (3,567 individuals) were sampled by the CN and 15 species (3,108 individuals) were sampled by the FN along with 14 species (577 individuals) by the TN, 7 species (107 individuals) by the GN, 6 species (59 individuals) by MT, and 5 species (95 individuals) by KN, respectively. Statistical analysis (MANOVA), based on CPUE of the fishing gears showed that fish species and numbers of the CN were significantly (p < 0.05) greater than those of any other sampling gears. In contrast, sampling gear of MT and KN showed the least efficiency in our survey. This survey is a preliminary results for the tests of sampling gear's efficiency in lentic ecosystems, thus further extensive studies are required for the verification.

Objectives: To clarify the association between dust from large construction sites and allergic and respiratory conditions among residents in Sejong city. Methods: We included 379 individuals older than 50 years from three areas of Sejong city; two areas near construction sites and one area for a comparison. Prevalence of self-reported allergic and respiratory conditions was compared across the three areas using logistic regression to adjust for covariates including age, gender, smoking, and educational attainment. A total of 16 individuals were interviewed to take details of the residents' experiences of construction work. Results: Those living in the nearby areas around construction sites were generally found to have the increased prevalence for all allergic and respiratory conditions. Odds Ratio(OR)s for cough and sneezing among the six symptoms and allergic rhinitis among the three diagnosed diseases reached statistical significance but only OR for cough remained significant after adjustment: adjusted OR for cough was 2.63 (95% CI, 1.07-6.46). Two relevant themes emerged from semi-structured interview were; 1) most residents from the affected area reported a considerable level of exposure to construction dust, 2) about half of them noted that construction dust influences allergic- and respiratory health. Conclusions: General pattern provides suggestive evidence that living close to construction sites may be positively associated with elevated risks of allergic and respiratory conditions. Efforts should be made to establish preventive measures and a comprehensive in-depth health impact assessment on this issue.

The purpose of this study was the assessment of the accuracy of Global Precipitation Measurement (GPM) Integrated Multi-Satellite Retrievals for GPM (IMERG), a rainfall data source derived from satellite images, for evaluation of its applicability to use in ungauged or inaccessible areas. The study area was the overall area of the Korean peninsula divided into six regions. Automated Surface Observing System (ASOS) rainfall data from the Korean Meteorological Administration and IMERG satellite rainfall were used. Their average correlation coefficient was 0.46 for a 1-h temporal resolution, and it increased to 0.69 for a 24-h temporal resolution. The IMERG data quantitatively estimated less than the rainfall totals from ground gauges, and the bias decreased as the temporal resolution was decreased. The correlation coefficients of the two rainfall events, which had relatively greater rainfall amounts, were 0.68 and 0.69 for a 1-h temporal resolution. Additionally, the spatial distributions of the ASOS and IMERG data were similar to each other. The study results showed that the IMERG data were very useful in the assessment of the hydro-meteorological characteristics of ungauged or inaccessible areas. In a future study, verification of the accuracy of satellite-derived rainfall data will be performed by expanding the analysis periods and applying various statistical techniques.

This study proposes an operational method of typhoon risk assessments in Korea, using Statistical analysis and probabilistic description of typhoon at a site. Two alternative simulation and fitting methods are discussed to predict the probabilistic typhoon wind speeds by indirect methods. A Commonly used indirect method is Russell's procedure, which generates about 1,000 Simulation data for typhoon winds, statistically evaluate the base-line distribution, and then fits the results to the Weibull distribution based on probabilistic description of climatological Characteristics and Wind field model of typhoon at a site. However, an alternative procedure proposed in this Paper simulates extreme typhoon wind data of about 150~200 years and directly fits the generated data to the Weibull distribution. The computational results show that the proposed simulation method is more economical and reasonable for typhoon risk-assessment based on the indirect method. And using the proposed indirect method, the probabilistic design wind speed for transmission towers in typhoon-prone region along the South-Western coast is investigated.

The purpose of this study was to assess the present status of the course content of Fundamental Nursing in accordance with the study objectives which were developed for the National Qualifying Examination by the first Faculty-Workshop in January, 1999 and the study objectives as related to other Nursing courses. The study sample included all schools of nursing and the members of the faculty for Fundamental Nursing of seventy schools(66.7%), out of the target population of 105, responded to a questionnaire which was developed by the research team. The collected data were analyzed by frequencies, percentages, means, and standard deviation using the SAS(Statistical Analysis System). The results are as follows : 1) According to this survey the course content of Fundamental Nursing as described in the study objectives for the National Examination, 223(86.77%) study objectives were included in the course of Fundamental Nursing by more than 70% of the schools of nursing, But twenty-three of the study objectives are not included by $30{\sim}50%$ of the schools of nursing. They consider this content to be taught in other courses. The study objectives, which less than 50% of the schools reported as being included in their course in Fundamental Nursing were, all study objectives for 'nursing assessment(communication)', 'nursing assessment (physical examination)', 'record and report', 'sex', and 'use of computer program for nursing diagnosis' and 'use of computerized nursing planning program' 2) Items that were not included in the study objectives for Fundamental Nursing but were included in course content for over 50% of the schools included, 'health of individual, family, community', 'change of nursing practice'. 'professionality of nursing' and all of the study objectives belonging to 'loss and grief' and 'nursing during all stages of surgical operations'. We hope that these results will be helpful in modifying the study objectives for the National Examination as developed by the first Faculty-Workshop and recommend the need for continuous survey research to produce content that is in accordance with study objectives and a National Examination that reflects the content of Fundamental Nursing.
