Background: Our aim was to investigate the efficacy of the Pap test in combination with the ThinPrep cytological test (TCT) in screening for cervical cancer in China. Design: From March 2006 to October 2008, 988 women with the mean age $46.4{\pm}10.5$ years (range, 23-80 years) were recruited to receive cervical cancer screening. Pap test results ${\geq}$ grade III and TCT findings ${\geq}$ ASCUS/AGUS were considered abnormal. Subjects with a Pap test result ${\geq}$ grade IIb received TCT. Colposcopy and biopsies were performed in all participants, and final diagnosis was based on pathological findings. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and Youden index for predicting CIN I or above were determined. Results: The sensitivity, specificity, PPV, NPV and Youden index of the Pap test were 43.1%, 97.2%, 70.0%, 91.9%, and 40.3%, respectively. The same values for TCT in predicting CIN were 80.0%, 63.2%, 16.0%, 97.3%, and 43.2%, respectively. The two tests in combination gave values for predicting CIN of 64.8%, 87.6%, 43.6%, 94.4%, and 53.5%, respectively. Combined testing exhibited the highest Youden index (53.4%). Conclusion: The Pap test with a reduced threshold in combination with the TCT has high sensitivity and high specificity in screening for cervical cancer.

Purpose. This study was conducted from the period of April 12th, 2017 to April 26th, 2017. The questionnaires were distributed among a group of 76 adults aged 20 years or older, who participated in the prevention program of the department of dental hygiene at Busan Metropolitan City. The negative questionnaire was finally analyzed. Methods. The SPSS program was used for analysis of this study. The general characteristics of the subjects were t-test and one-way, ANOVA(by Scheffe post-test) for a PHP index (Patient Hygiene Performance index) according to frequency analysis, general characteristics, smoking and drinking behavior, and dietary behavior. Results. As a result of an examination of the PHP index(Patient Hygiene Performance index) ac- cording to smoking and drinking behavior, the amount of alcohol drunk was statistically higher than that of 'soju that was not drunk'(P<0.05). As a result of the PHP index (Patient Hygiene Performance index) according to dietary behavior, 'vegetarians' were statistically higher than 'Carnivorous oriented' individuals (P<0.05). Moreover, individuals who regularly 'drank almost no water' were statistically significantly higher than those who 'drank water steadily'.(P<0.05). Conclusion. As a result, appropriate management is required for oral health of the patient, Oral health education is needed to systematically consider smoking, drinking, and eating habits when taking into consideration the individual oral environment.

PURPOSE: The purpose of this study was to establish the reliability and validity of the Wheelchair User's Shoulder Pain Index (WUSPI), which was translated into Korean for long-term wheelchair users. This index measured 15 functional activities, including transfer, self-care, wheelchair mobility and general activities. METHODS: To assess test-retest reliability, 23 long-term wheelchair users completed this self-administered index twice within the same day. Reliability was determined by the intraclass correlation coefficient (ICC), and Cronbach's alpha was used to measure internal consistency. To examine concurrent validity, 21 long-term wheelchair users completed the questionnaire, and we examined the correlation between the index score and the shoulder range of motion measurements. RESULT: The results showed that the intraclass correlation for test-retest reliability of the total index score ranging from .88 to .99 was good to excellent. Additionally, Cronbach's alpha was .96. The internal consistency indicated excellent. Concurrent validity showed negative correlations of total index score to range of motion measurements of shoulder flexion (rho=-.58), extension (rho=-.09), abduction (rho=-.59), external rotation (rho=-.07) and internal rotation (rho=-.3), suggesting a relationship of total index score to loss of shoulder range of motion. CONCLUSION: The Korean WUSPI shows not only high reliability and internal consistency, but also concurrent validity with loss of shoulder flexion and abduction.

In this study, a horticultural therapy program was performed by employing the anger experienced by people during daily life activities in the emotion regulation strategy-based program to identify the influence of the horticultural program on anger control in the caregivers for patients with dementia. To measure this influence, two tools were used: a self-administered questionnaire survey, which is a subjective test, and an instrumental test, which can measure the physical index that detects the physical changes through anger. For the preliminary test, depression, stress, self-esteem, anxiety, and anger state-characteristic were tested using the self-administered questionnaire. For the follow-up test, the self-administered survey and the test using the physical index were performed in a manner similar to that of the preliminary test. The self-administered questionnaire comprised questions suitable to this study and considered the age, education level, and economic aspect of the subjects. The test results indicated that the experimental group subjected to the emotion regulation strategy-based horticultural therapy showed very significant reduction in depression and anger and significant reduction in stress, self-esteem, and anxiety. In the physical index test, the systolic and diastolic blood pressures were reduced, and the pulse rate and respiration rate reduced before and after the therapy, thus, proving the effectiveness of the therapy in anger control.

부음기관의 기능이 정상인 경우 1,000Hz 이하의 저음역에서 골도관치는 외이도를 폐새 하였을 때와 개방하였을 때 약 20dB의 차이를 나타낸다. 그러나 외이도를 폐색하였을 때나 개방하였을 때 골도관치에 변화가 없으면 전음기관에 병변이 있음을 의미한다. 1891년에 Bing이 처음으로 외이도폐색에 의한 골도검사를 발표한 이래 여러 학자들에 의하여 본검사가 유용한 임상경력검사의 한방법으로서 인정되고Bing test로 알려지고 있다. Sullivan은 1947년에 250Hz, 500Hz, 1,000Hz에서 외이도를 폐색하였을 때와 개방하였을 때의 골도관치의 차이를 합한 것을 "Occlusion Index"라고 명명하였다. 이에 저자들은 bing test의 임상청각학적 의의를 검토하고자 정상인 40이, 만성중이염환자 20이, 감각신경성난청환자 14이를 대상으로 순음청력검사, Bing test및 impedance audiometry를 시행하고 occlusion index와의 상관관계를 검토하여 다음과같은 결과를 얻었다. 1. Occlusion index는 정상인 40좌에서는 $33.10\pm1.68dB,$ 만성중이염환자 20이에서는 $3.10\pm0.69dB,$ 감각신경성난청환자 14이에서는 28.10=4.05 dB이었다. 2. 정상인 40이의 static compliance는 범위가 0.22~0.75cc, 평균치가 0.64cc, 5.D가 0.05이었다. 3. Static compliance가 작을수록 occlusion index는 컸고, static compliance가 클수록 occlusion index 는 작아지는 영향을 나타내고 있음을 관찰하였다.

This paper presents the results of an experimental investigation of the correlation between the lubrication characteristics of an engine and its fuel economy. Improving the lubrication characteristics of the engine oil is one of the most efficient ways to improve a car's fuel economy. The methods to accomplish this include lowering the viscosity, adding a friction modifier and optimizing the shear stability index of a viscosity index improver. In addition, it is necessary to use different methods to reduce the friction to individual lubrication areas, because different lubrication regimes are used for different engine parts. The experimental investigation in this study is based on design of experiments ; this paper presents the results of a modified Sequence VID test, which is an ASTM standard test used to measure the effects of automotive engine oils on the fuel economy of passenger cars. The results demonstrate the effects of the following lubrication factors on the fuel economy : the low temperature cranking viscosity, high-temperature high shear (HTHS) viscosity, friction modifier, polymer type and shear stability index of the viscosity index improver. Moreover, this study involves an analysis of variance based on design of experiments. The test results show that the HTHS viscosity, friction modifier and shear stability index of the viscosity index improver are more effective than the other factors. Therefore, lowering the viscosity, adding a friction modifier and optimizing the shear stability index of a viscosity index improver should be considered to improve fuel economy.

Background: The rising prevalence of asthma may be associated with the rising prevalence of obesity in developed nations. There are several studies showing that obesity increases the risk of asthma in adults. We investigated the association of each body composition scale and bronchial hyper-responsiveness. Methods: This study involved a retrospective review of the existing records for 279 subjects with respiratory symptoms, who underwent a pulmonary function test, a methacholine challenge test and a body composition test between May 2007 and June 2009. Results: Of the 279 subjects, 179 (64%) were female. There was a statistically significant difference in fat free mass and in fat free mass index between the normal bronchial responsiveness group and bronchial hyper-responsiveness group (p=0.036; p=0.000). There was no significant differences in body mass index, in fat mass and fat free mass index in the normal bronchial responsiveness group and bronchial hyper-responsiveness group in males. However in females, body mass index and fat free mass index were increased in the bronchial hyper-responsiveness group (p=0.044; p=0.000). Total body water (kg), fat free mass (kg) and soft lean mass (kg) were significantly different between the normal bronchial responsiveness group and bronchial hyper-responsiveness group (p=0.002; p=0.000; p=0.000). Conclusion: This study showed significant differences in fat free mass and in fat free mass index between the normal bronchial responsiveness group and the bronchial hyper-responsiveness group. In females, BMI, soft lean mass, and total body water showed significant differences between the normal bronchial responsiveness group and the bronchial hyper-responsiveness group. We concluded that bronchial hyper-responsiveness was associated with not only body mass index but also fat free mass index in female bronchial asthma.
