STATEMENT OF PROBLEM: How the ISQ values measured by Osstell(TM) and Osstell(TM) Mentor are related, and whether the ISQ values acquired from the two machines changes in accordance with changes in implant stability are not yet fully understood. PURPOSE: The aim of this study was to find out correlation between the ISQ values acquired from Osstell(TM) and Osstell(TM) Mentor, and to evaluate the clinical effectiveness and accuracy of two devices. MATERIAL AND METHODS: Sixty two implants were inserted into 47 patients, and their ISQ values were measured using Osstell(TM) and Osstell(TM) Mentor. In the first stage surgery, the ISQ values of forty four implants inserted into thirty five patients were measured. In the second stage surgery, the values of fifty implants inserted into thirty seven patients were measured. The values were analyzed to determine the difference between the mean ISQ values of Osstell(TM) and Osstell(TM) Mentor. In addition, the correlation between implants used in the first and second stage of surgery with regard to their types and areas of insertion were analyzed. The difference between the ISQ values of 32 implants in each patient during the first and second stage was analyzed. The statistical assessment was carried out using SPSS V. 12.0 for Win. (SPSS Inc., Chicago, USA). The Pearson correlation coefficient was used to examine the correlation between Osstell(TM) and Osstell(TM) Mentor in the first and second stages of surgery, whereas the difference between their ISQ values was evaluated using a paired t-test. RESULTS: In the first stage, the mean ISQ value for Osstell(TM) and Osstell(TM) Mentor was 70.84 and 75.09, respectively, showing a significant difference (P < .01). In the second stage, the mean ISQ value of Osstell(TM) and Osstell(TM) Mentor was 71.76 and 75.94, respectively, also showing a significant difference (P < .01). The difference between the ISQ values in patients in the first and the second stages was significant with both instruments. CONCLUSION: The significant difference in the values obtained using the Osstell(TM) and Osstell(TM) Mentor between the first and second stages of implant surgery indicates that these values can be a convenient and precise way for evaluating the implant stability in clinical practice.

PURPOSE: To assess the reproducibility and reliability of applanation A-scan ultrasonography (Pacscan 300A, Sonomed Inc., Chicago, IL, USA) and optical measurements with IOL Master(R) (Carl Zeiss Meditec, Germany), Pentacam(R) (Oculus, Wetzlar, Germany), and Orbscan II(R) (Orbtek Inc., Laredo, TX, USA) when measuring anterior chamber depth (ACD). METHODS: In this study of 188 eyes of 94 patients, ACD estimation prior to cataract surgery was preformed by the applanation A-scan method and IOL Master(R), Pentacam(R), and Orbscan II(R) optical methods. Repeatability from each device was evaluated by coefficient of variation, standard deviation, and intraclass correlation coefficient. RM-ANOVA on Ranks was used to compare the differences in ACD among the devices. The Bland-Altman plot was performed to assess agreement in measurements between the devices. RESULTS: The mean ACD according to the applanation A-scan method and IOL Master(R), Pentacam(R), and Orbscan II(R) optical methods were 2.89 +/- 0.49 mm, 3.25 +/- 0.45 mm, 3.21 +/- 0.46 mm, and 3.19 +/- 0.47 mm, respectively, and the differences were statistically significant (p < 0.01). The coefficient of variation for the 4 methods was 2.50% in the A-scan, 0.87% in the IOL Master(R), 1.25% in the Pentacam(R), and 1.04% with Orbscan II(R), and reproducibility was higher with the optical principle devices. The correlation coefficient between A-scan and IOL Master(R) was 0.65, between IOL Master(R) and Pentacam(R) 0.91, between IOL Master(R) and Orbscan II(R) 0.90, between A-scan and Pentacam(R) 0.69, between A-scan and Orbscan II(R) 0.71, and between Pentacam(R) and Orbscan II(R) 0.93. CONCLUSIONS: Applanation A-scan provided lower measurements for ACD compared with IOL Master(R), Pentacam(R) and Orbscan II(R). There was good agreement between results obtained with the latter 3 methods, and reproducibility was high with optical measurements. The coefficient of variation was low for IOL Master(R).

4.Evaluation of Esophageal Motor Function With High-resolution Manometry.
Journal of Neurogastroenterology and Motility 2013;19(3):281-294
For several decades esophageal manometry has been the test of choice to evaluate disorders of esophageal motor function. The recent introduction of high-resolution manometry for the study of esophageal motor function simplified performance of esophageal manometry, and revealed previously unidentified patterns of normal and abnormal esophageal motor function. Presentation of pressure data as color contour plots or esophageal pressure topography led to the development of new tools for analyzing and classifying esophageal motor patterns. The current standard and still developing approach to do this is the Chicago classification. While this methodical approach is improving our diagnosis of esophageal motor disorders, it currently does not address all motor abnormalities. We will explore the Chicago classification and disorders that it does not address.

This study was conducted to evaluate the sanitary performance and knowledge of elementary school foodservice employees. The specific aim of this study was to decipher why employees cannot apply learned knowledge to real work situations. In total, 437 foodservice operation employees attended a regular sanitary education program under the auspices of Seoul Gangdong and Gangseo district offices. The five sanitary practice performance evaluators included personal hygiene, ingredient control, process control, safety management, and sanitary education. These dimensions were self-evaluated using the Likert 5-point scale. Collected data were subjected to descriptive and comparative analysis using SPSS (Version 12.0, SPSS Inc., Chicago, IL, USA) statistical package. The main results are summarized as follows: 93.6% of the respondents were women and 57% were aged between 40~49. Total mean score of the five sanitary performance evaluators was 4.73 for elementary school. Ingredient control score was 4.86, process control 4.80, and personal hygiene 4.79. But the sanitary education field score was 4.48, which was significantly lower than the total mean score. Safety management score was 4.73.

OBJECTIVES: To evaluate the management and awareness of osteoporosis based on general characteristics, problems, and menopausal status. METHODS: Two hundred twenty women were recruited from the Department of Obstetrics and Gynecology of a university hospital between January 2010 and December 2010. The participants completed self-questionnaires about the management of osteoporosis. We determined the correlation of the management of osteoporosis between pre- and post-menopausal women using ANOVA with SPSS version 12.0K (SPSS Inc., Chicago, IL, USA). RESULTS: The mean age was 52.5 +/- 9.4 years (range, 43~83 years). One hundred twenty-four women were postmenopausal (56.1%). Postmenopausal women were statistically more likely to have examinations for osteoporosis, and take calcium and engage in exercise to prevent osteoporosis. CONCLUSION: It is necessary to educate and counsel premenopausal women and patients at high-risk for fracture about the management of osteoporosis.

PURPOSE: To survey the radiographic examination protocol for lateral cephalometric radiographic examinations and to measure their patient doses in Korea and to compare the dose according to the size of hospital, the type of image receptor system, and the installation duration. MATERIALS AND METHODS: The radiographic examination protocols (kVp, mA, and exposure time) for lateral cephalometric radiography were surveyed with 61 cephalometric radiographic equipments and their patient dose-area product (DAP) measured with a DAP meter (DIAMENTOR M4-KDK, PTW, Freiburg, Germany) for 51 cephalometric radiographic equipments. The radiographic examination protocols and patient doses were compared according to the size of hospital (university dental hospital, dental hospital, and dental clinic), the type of image receptor system (film-based, DR and CR type) and the installation duration, respectively. SPSS 12.0.1 for Windows (SPSS Inc., Chicago, USA) was used for independent t-test and ANOVA test. RESULTS: The average protocols were 77.0 kVp, 12.7 mA, 6.2 second for cephalometric radiography. The average patient dose (DAP) was 128.0 mGy cm2 and 3rd quartile dose (DAP) 161.1 mGy cm2 for cephalometric radiography for adult male. There was no statistically significant difference at average patient DAP according to the size of hospital, the type of image receptor system, and the installation duration, repectively. CONCLUSION: The average patient dose was 128.0 mGy cm2 and the third quartile patient dose 161.1 mGy cm2 for lateral cephalometric radiography for adult male in Korea.

Chinese Journal of Cancer 2012;31(7):315-318
A global collaborative effort is pivotal to conquer cancer. Themed "Emerging role of China in global clinical development of novel anti-cancer drugs", the US Chinese Anti-Cancer Association (USCACA) held its 4th annual meeting in Chicago on June 2, 2012, in conjunction with the American Society of Clinical Oncology (ASCO) annual meeting to further bridge the US and China together to outsmart cancer. Although a young organization, USCACA has made significant contributions to this goal in the 3 years since its inception through extensive collaboration with academic organizations, the pharmaceutical industry, and governmental agencies. USCACA has engaged various stakeholders in developing translational and personalized medical strategies to facilitate new anti-cancer drug development and clinical trials in China. USCACA has initiated and implemented the USCACA-National Foundation for Cancer Research (NFCR) scholarship to encourage overseas returnees to continue cancer research in China. USCACA announced the Hengrui-USCACA scholarship to fund clinical trial staff from China to conduct the observation of early oncologic clinical trials in the US. During the annual meeting, distinguished panelists and the audience discussed the following critical topics:(1) oncologic translational research and early development capabilities in China;(2) novel chemical entity development and partnership with Chinese companies; and (3) Chinese participation in global anti-cancer drug development. USCACA will continue to promote collaborations among cancer researchers and clinicians in the US and China by engaging in more frequent communications and joint efforts across fields, disciplines, and countries, diligently working together toward curing and eliminating cancers.

Journal of Korean Neurosurgical Society 2013;54(3):207-210
OBJECTIVE: To compare spinopelvic parameters in young adult patients with spondylolysis to those in age-matched patients without spondylolysis and investigate the clinical impact of sagittal spinopelvic parameters in patients with L5 spondylolysis. METHODS: From 2009 to 2012, a total of 198 young adult male patients with spondylolysis were identified. Eighty age-matched patients without spondylolysis were also selected. Standing lateral films that included both hip joints were obtained for each subject. Pelvic incidence (PI), sacral slope (SS), pelvic tilt, lumbar lordosis angle, sacral inclination, lumbosacral angle, and sacral table angle were measured in both groups. A comparative study of the spinopelvic parameters of these two groups was performed using SPSS 15.0 (SPSS Inc., Chicago, IL, USA). RESULTS: Among the aforementioned spinopelvic parameters, PI, SS and STA were significantly different between patients with spondylolysis and those without spondylolysis. PI and SS were higher in the spondylolysis group than in the control group, but STA was lower in the spondylolysis group than in the control group. CONCLUSION: PI and SS were higher in the spondylolysis group than in the control group, but STA was lower in the spondylolysis group than in the control group. Patients with spondylolysis have low STA at birth, which remains constant during growth; a low STA translates into high SS. As a result, PI is also increased in accordance with SS. Therefore, we suggest that STA is an important etiologic factor in young adult patients with L5 spondylolysis.
