This study, performed to analyze the factors associated with health and cancer screening using preventive programs form health insurance among the women of a community, through a survey of about 923 women in Euijungbu-city. The subjects of the study were selected by a proportional cluster sampling method. The self-reported questionnaire was intended to fine factors associated with health screening and cancer screening. The results of this study were as follows: 1. In the case of health screening using health insurance, 14.1% of the subjects turned out to have been screened once or more in their respective life-time. Reasons given for non-participation in the screening were : 'lacking screening information', a belief that' it's not useful' and a belief that they' weren't sick'. 2. The factors associated with health screening behavior were age, educational level, number of doctor visits, BMI and health promotion behavior(p<0.01, p<0.05). Also, the factors associated with health screening behavior were cue to action and health status, and the predictors on health screening behavior were age and health promotion behavior(p<0.01, p<0.05). 3. In the case of cancer screening through the health insurance, 7.4% of the subjects turned out to have been screened once or more respectively in their life-times. Reasons given for non-participation in the screening were : 'lacking screening information', a belief they 'weren't sick' and that it's not useful'. 4. The factors associated with cancer screening behavior were age, educational level, income, alcholol intake, exercise, number of doctor visits and BMI(p<0.01, p<0.05). Aditional factors associated with cancer screening behavior were cue to action, health belief score and health status. Predictors for cancer screening behavior were: age, health belief score, screening attitude and health status(p<0.01, p<0.05). As indicated by the above results, a lack of information was an important factor for a lack of participation in screening. Age and cue to action were also important factors in promoting the cancer screening rate. Therefore, a dissemination of information about cancer screening contributes to the promotion of a screening rate, and cooperation between health insurance and local health cancer facilitates to be public the community-based cancer screening program.

To investigate the spatio-temporal distributions of the mixotrophic dinoflagellate Yihiella yeosuensis in Korean coastal waters and its grazing impact on prey populations, water samples were seasonally collected from 28 stations in the East, West, and South Seas of Korea and Jeju Island from April 2015 to October 2018. The abundances of Y. yeosuensis in the water samples were quantified using quantitative real-time polymerase chain reaction (qPCR). Simultaneously, the physical and chemical properties of water from all sampled stations were determined, and the abundances of the optimal prey species of Y. yeosuensis, the prasinophyte Pyramimonas sp. and the cryptophyte Teleaulax amphioxeia, were quantified using qPCR. Y. yeosuensis has a wide distribution, as is reflected by the detection of Y. yeosuensis cells at 23 sampling stations; however, this distribution has a strong seasonality, which is indicated by its detection at 22 stations in summer but only one station in winter. The abundance of Y. yeosuensis was significantly and positively correlated with those of Pyramimonas sp. and T. amphioxeia, as well as with water temperature. The highest abundance of Y. yeosuensis was 48.5 cells mL^-1 in Buan in July 2017, when the abundances of Pyramimonas sp. and T. amphioxeia were 917.6 and 210.4 cells mL^-1, respectively. The growth rate of Y. yeosuensis on Pyramimonas sp., calculated by interpolating the growth rates at the same abundance, was 0.49 d^-1, which is 37% of the maximum growth rate of Y. yeosuensis on Pyramimonas sp. obtained in the laboratory. Therefore, the field abundance of Pyramimonas sp. obtained in the present study can support a moderate positive growth of Y. yeosuensis. The maximum grazing coefficient for Y. yeosuensis on the co-occurring Pyramimonas sp. was 0.42 d^-1, indicating that 35% of the Pyramimonas sp. population were consumed in 1 d. Therefore, the spatio-temporal distribution of Y. yeosuensis in Korean coastal waters may be affected by those of the optimal prey species and water temperature. Moreover, Y. yeosuensis may potentially have considerable grazing impacts on populations of Pyramimonas sp.

Test turnaround time (TAT) is the lead time from reception to reporting. In the complete blood cell count (CBC), 4 units of the XE-2100 (Sysmex Corp., Japan) processed around 80% of quantity, 1 unit of the LH-780 (Beckman-Coulter Incorp., USA) processed around 10% and 1 unit of ADVIA-2120 (Siemens AG, Munich, Germany) processed around 10%. We analyzed the change in the TAT for the CBC for over 7 years, from January of 2005 to December of 2011. The delta check made alterations of delta to WBC, hemoglobin, hematocrit, platelet and metamyelocyte, however, did not made them to band neutrophil, eosinophil, basophil and monocyte. The panic value check made alterations of panic value to hemoglobin, hematocrit, platelet and monocyte. In the criteria of currently slide review, LH-780 and ADVI-2120 analyzers prepared suspect flags of "Blast, Imm NE2, Immature granulocyte, Imm NE1, Left shift, Variant lymphocyte, Atypical lymphocyte, Platelet clumps and NRBC". The New slide review in the XE-2100 analyzer altered the preparations of a smear slide more than a "Platelet clumps flag(${\geq}200unit$), a single flag excluding the "Platelet clumps flag (${\geq}250unit$) and a multiple flag (${\geq}200unit$)". Also, below the 240 unit, medical technologists prepared manual slides selectively according to their evaluations. The automatic reporting rate was 33.4% without alterations, whereas it was 41.0% without alterations, and was thus improved by 7.6%. The slide review rate was 15.2% before using the Q-flag limit, whereas it was 12.1% for a reduce 3.1%. TAT was 45 minutes without the creation alterations of the delta and panic value checks, whereas it was 35 minutes after making alterations of the delta and panic value checks and thus was shortened by 10 minutes. We came to the conclusion that the establishment and operation of delta and panic value checks and slide review criteria suitable for laboratory environment can reduce unnecessary smear slides, re-checking, re-sampling, re-testing, telephone inquiries and concentrated workloads during specific times of the day.

Objective: The purpose of this study was to investigate relations and effectiveness about mountain climbling exercise with different level of support surfaces by analyzing heart rate and EMG data. A total of 10 male college students with no musculoskeltal disorder were recruited for this study. Method: The biomechanical analysis was performed using heart rate monitor (Polar V800, Polar Electro Oy, Finland), step-box, exercise mat, and EMG device (QEMG8, Laxtha Inc. Korea, sampling frequency = 1,024 Hz, gain = 1,000, input impedance > 1012 Ω, CMRR > 100 dB). In this research, step-box were used to create different surface levels on the upper body (flat surface, 10% of subject's height, 20% of subject's height, and 30% of subject's hight). Based on these different conditions, data was collected by performing mountain climbing exercise during 30 seconds. Subjects were given 5 minutes of break to prevent muscular fatigue after each exercise. For each dependent variable, a one-way analysis of variance with repeated measures was conducted to find significant differences and Bonferroni post-hoc test was performed. Results: The results of this study showed that exercise intensity was reduced statistically as increased surface level on the upper body. Muscle activity of the upper rectus abdominis and biceps femoris for 30% of surface level was significantly higher than the corresponding values for flat surface. However, the opposite was found in the rectus femoris. In general, muscle activity of the lower rectus abdominis, erector spinae, external oblique abdominis, and gluteus maximus increased when surface level increased, but the differences were not significant. Conclusion: As a result, the increase in surface level of the body would change muscle activity of the upper body, indicating that different surface level of the upper body may cause significant effect on particular muscles to be more active during mountain climbing exercise. Based on results of this study, it is suggested to set up an appropriate surface level to target particular muscle to expect an effective training. It is also important to set adequate surface levels to create an effective training condition for preventing exercise injuries.

Objectives : This study is aimed to survey Korean Medicine Doctors's perceptions in Korean Medicine Clinical Practice Guideline and Standard Korean Medicine Clinical Pathways for its spread(to increase utilization in clinical sites). Methods : The research population was set at 14,831 Korean medical institutions registered with the Health Insurance Review and Assessment Service for sampling representative of Korean Medicine Doctors, and the final 2,007 subjects were selected in consideration of the research period and budget. This survey was conducted based on a telephone survey, and in some cases, a fax or e-mail survey was also conducted together. Six questions were asked about the perception of 'Korean Medicine Clinical Practice Guideline and Standard Korean Medicine Clinical Pathways', and three questions about the characteristics of the respondent. Results : The rate of recognizing Korean Medicine Clinical Practice Guideline was 36.1%. Those who worked at Korean medicine hospitals, were under 39 years of age, and had less than 11-20 years of experience as an Korean medical doctor were more likely to be aware of it. Regarding the experience of using Korean Medicine Clinical Practice Guideline, the rate of 'not used in the past and not used now' was very high at 82.9%, but the intention to use it in the future was high at 60.7%. About the Korean Medicine Clinical Pathways, 79.9% of respondents answered that they did not know. 80.6% of respondents recognized the need for the development of clinical manuals such as Korean Medicine Clinical Practice Guideline and Standard Korean Medicine Clinical Pathways. Conclusion : Their low awareness of Korean Medicine Clinical Practice Guideline seems to affect its low utilization. Therefore, active education and public relations are required in the future.

Purpose - Previous studies about corporate image generally explore how corporate image affects a company's effectiveness from the consumer view. However this study attempts to explore the impacts of corporate image (reliability, friendly, corporate social responsibility, and innovation) on employees' altruistic behaviors in the franchise industry context. This study also examine whether organizational trust and affective commitment play a mediating role in the relationship between corporate image and employees' altruistic behaviors. The authors developed several hypotheses to achieve these purposes. Research design, data, and methodology - The data were collected from employees in food-service franchise companies located in Seoul, Korea. Among a total of 363 questionnaires distributed, 294(response rate of 81%) questionnaires were returned. After excluding 18 invalid respondent questionnaires, 276 valid questionnaires(response rate of 76%) were coded and analyzed using frequency, confirmatory factor analysis, correlations analysis, and structural equation modeling with SPSS 21 and SmartPLS 3.0. Result - The findings of the study are as follows: First, friendly, CSR, and innovation had positive effects on organizational trust, but reliability did not have a significant effect on organizational trust. Second, reliability and friendly of corporate image had positive effects on affective commitment, but CSR and innovation did have a significant effect on affective commitment. Third, organizational trust and affective commitment had positive effects on employees' altruistic behaviors. Conclusions - The aim of this study is to investigate the franchise corporate image as a significant influencing factor of employees' altruistic behaviors. The data were collected from only employees from franchising companies. The findings might vary from position to position. Future studies need to collect and compare data from managers. Future studies need to consider other variables that affect employees' altruistic behaviors. For example, leadership and market orientation might influence employees' attitude and behaviors. Also, future research should include other variables and it may have limitations in sample representative because of sampling franchise corporate in Seoul. Future studies will include franchise corporate all over the country. Future studies can also consider other variables (e.g., job performance and turnover intentions) to measure employee performance at the level of individuals and identify the impact of employee performance on business performance at the level of corporate.

수산물은 많은 국가의 주요한 단백질 공급원이며 소비가 증가하고 있다. 우리나라도 수산물 소비는 증가하는 반면 자급률은 낮아지고 있으며, 수산물의 수입량이 증가함에 따라 안전관리의 중요성이 높아지고 있다. 국내로 수입되는 수산물은 110여 개 국가로부터 수백 종에 이르며, 수입 수산물의 안전관리를 검사관의 경험에만 의존하는 것은 한계가 있다. 데이터를 기반으로 수입 수산물 통관검사 결과를 예측할 수 있는 모델을 개발하여 수입신고서가 제출되었을 때 수산물의 부적합 가능성을 판단하는 머신러닝 분류 모델을 생성한다. 수입수산물 통관검사 결과 부적합율은 1% 미만으로 매우 낮은 불균형 데이터이므로 이러한 특성을 보완할 수 있는 샘플링 방법을 비교 연구하였고, 분류결과를 해석할 수 있는 전처리 방법을 적용하였다. 여러 가지 머신러닝 기반의 분류모델 중에서 랜덤포레스트와 XGBoost가 좋은 성능을 보였다. 통관검사 결과 적합과 부적합을 모두 잘 예측하는 모델은 ADASYN과 원-핫 인코딩을 적용한 랜덤포레스트 기본 모델이며 정확도 99.88%, 정밀도 99.87%, 재현율 99.89%, AUC 99.88%이다. XGBoost는 오버샘플링과 인코딩 종류에 상관없이 모든 지표가 90%를 넘겨 가장 안정적인 모델이다.
