Purpose: The purpose of this study was to determine if monocular and binocular accommodative facility tests would be useful in diagnosing general binocular dysfunctions. Methods: 95 symptomatic children, who were selected from comprehensive vision tests, were classified into four groups (29 subjects with accommodative dysfunctions, 28 subjects with vergence dysfunctions, 25 subjects with combined accommodative and vergence dysfunctions, 13 subjects with normal binocular functions). Monocular and binocular accommodative facility was measured with ${\pm}$2.00 D flipper lenses. Results: Statistical analysis revealed that binocular accommodative facility measurement was significantly lower than monocular accommodative measurement in the vergence dysfunction group (p<0.01). However, there were no differences between monocular and binocular accommodative facility measurements in the group of accommodative or combined accommodative and vergence dysfunction (p>0.05). In addition, subjects with general binocular dysfunctions performed significantly poorer than subjects with normal binocular function on monocular and binocular accommodative facility (p<0.000). Conclusions: As a result of this study, monocular and binocular accommodative facility test, which could differentiate dysfunction from normal as well as between dysfunctions, indicated useful means for diagnosis of general binocular dysfunctions.

Background: Health is affected by various local factors. This study aims to investigate the age-standardized mortality variation of Seoul as well as the characteristics of the factors related to the mortality variation. Methods: The Korea Community Health Survey data, Seoul Survey data, Seoul statistics, and e-regional indicators of the National Statistical Office were used. To investigate the basic boroughs standardized mortality variation in Seoul, external quotient, coefficient of variation (CV), and systematic component of variation (SCV) values were suggested; correlation analysis and multiple regression analysis were conducted to investigate the characteristics related to standardized mortality rate. Results: The highest and the lowest standardized mortality rate of Seoul by boroughs had as much as 1.4 times difference; a low level of variation was shown in CV by 8.2; and was shown in SCV by 79. As a result of the multiple regression analysis of the factors that affect standardized mortality variation, the higher the rate of householders with college or higher, the lower the standardized mortality rate, and the higher the high-risk drinking rate, the higher the standardized mortality rate. Of the two, the rate of householder with a degree equivalent or higher than college was shown to have the biggest impact, followed by high-risk drinking rate. Conclusion: We found a variation in age-standardized mortality rate of boroughs in Seoul. The results suggest that policy makers should take into account socioeconomic environmental characteristics of community in developing community-based health promotion rather than focusing on lifestyle changes of residents.

The purpose of this research is to assess th iron nutritional status of pregnant women and to evaluate the appropriateness of the present cut off levels of hemoglobin(Hgb), hematocrit(Hct) and total iron binding capacity(TIBC) for assessing iron deficiency status. Pregnant women who were visiting public helath centers in Ulsan were interviewed and agreed to attend the study. Blood sample was taken and biochemical analysis of blood was performed. The collected data were classified into 3 trimesters by gestational age and then statistical analysis was performed. The prevalence of anemia in all subjects was 32.3% by WHO criteria(Hgb < 11.0g/dl) and 17.8% of all subjects was iron deficient anemia by CDC criteria(Hgb < 11.0/dl and serum ferritin < 12.0ug/l). Since the iron deficient anemia generally occures at the last stage of iron deficiency, it is not efficient to diagnose and prevent the iron deficient anemia in pregnant women by using the present cut off level of Hgb. Therefore, the new cut off level of iron status indices is necessary for assessing iron deficiency in early pregnancy before manifestation of anemia and for reducing the prevalence of anemia in later pregnancy. For this reason, the present cut off levels of iron status indices were estimated and compared by assessing the iron deficiency judged by serum ferritin level (<12.0ug/l)as true iron deficiency. It follows from the results of this research that present cut off levels of Hgb, Hct and TIBC were very insensitive in identifying the subjection with iron deficiency. The appropriate cut off levels of Hgb were 11.5g/dl for total period of pregnancy, 12.0g/dl for 1st and 3rd trimester, and 11.5g/dl for 2nd trimester. The cut off level of Hct was 34.0% for total period for pregnancy, 35.0% for 1st trimester, and 34.0% for 2nd and 3rd trimester. The cut off level of TIBC was 400ug/dl for total period, 360ug/dl for 1st 2nd trimester, and 450ug/dl for 3rd trimester.

Objectives : The mortality rate of subarachnoid hemorrhage(SAH) has been reduced recently due to refinement of microsurgical technique and improved perioperative management. Also, many survivors of SAH show excellent neurological recoveries. However, we found that a high proportion of the survivors do not fully regain their premorbid status in cognitive and memory function. Object of this study is to evaluate which factors might influence on cognitive and memory impairment in ruptured aneurysmal SAH patients. Methods : In this prospective study, a series of 66 patients with aneurysmal subarachnoid hemorrhage(SAH) from 1996 to 1998, most of whom had a "good" or "fair" neurological outcome, were assessed with various tests of cognition and memory function. All patients underwent clipping operation by pterional approach. Right side approach was performed in 16 case and left 21 cases. K-WAIS(Korean-Wechsler Adult Intelligence Scale) was used as method of cognition and memory function test. The time interval between SAH and assessment varied between 4 months and 8 months, averaging 6.2 months. Statistical analyses were carried out for each test score to see whether aneurysm site(A-com : non A-com), route of approach, age and sex, vasospasm, Hunt-Hess grade and Fisher CT group at admission, Glasgow Outcome Scale(GOS) at discharge affect cognitive and memory function. Results : Aneurysm site was not shown to be associated with performance on any test, and the initial grade (Hunt-Hess grade, Fisher CT group) of SAH and vasospasm had only minimal predictive values. The grade at discharge( GOS) was proved to be the best predictor of impairment of cognition and memory function within 1 year after operation. Conclusion : The authors conclude that the diffuse effects of SAH are more important than focal neuropathology in relation to cognitive impairment in this group of patients.

Prostate cancer (PCa) remains one of the most widespread and perplexing of all human malignancies. Assessment of gene expression is thought to have an important impact on cancer diagnosis, prognosis and therapeutic decisions. In this context, we explored combined expression of PCa related target genes AMACR and PCA3 in 126 formalin fixed paraffin embedded prostate tissues (FFPE) from Moroccan patients, using quantitative real time reverse transcription-PCR (RT-qPCR). This quantification required data normalization accomplished using stably expressed reference genes (RGs). A panel of twelve RG was assessed, data being analyzed using GenEx V6 based on geNorm, NormFinder and statistical methods. Accordingly, the hnRNP A1 gene was identified and selected as the most stably expressed RG for reliable and accurate gene expression quantification in prostate tissues. The ratios of both PCA3 and AMACR gene expression relative to that of the hnRNP A1 gene were calculated and the performance of each target gene for PCa diagnosis was evaluated using receiver-operating characteristics. PCA3 and AMACR mRNA quantification based on RT-qPCR may prove useful in PCa diagnosis. Of particular interesting, combining PCA3 and AMACR quantification improved PCa prediction by increasing sensitivity with retention of good specificity.

Background: Cancer screening rates are lower in Japan than those in western countries. Health professionals publish procancer screening messages on the internet to encourage audiences to undergo cancer screening. However, the information provided is often difficult to read for lay persons. Further, anti-cancer screening activists warn against cancer screening with messages on the Internet. We aimed to assess and compare the readability of pro- and anti-cancer screening online messages in Japan using a measure of readability. Methods: We conducted web searches at the beginning of September 2016 using two major Japanese search engines (Google.jp and Yahoo!.jp). The included websites were classified as "anti", "pro", or "neutral" depending on the claims, and "health professional" or "non-health professional" depending on the writers. Readability was determined using a validated measure of Japanese readability. Statistical analysis was conducted using two-way ANOVA. Results: In the total 159 websites analyzed, anti-cancer screening online messages were generally easier to read than pro-cancer screening online messages, Messages written by health professionals were more difficult to read than those written by non-health professionals. Claim ${\times}$ writer interaction was not significant. Conclusion: When health professionals prepare pro-cancer screening materials for publication online, we recommend they check for readability using readability assessment tools and improve text for easy comprehension when necessary.

Objectives : This study investigated the influence of traumatic experience on the ego identity, self-esteem, and general psychopathology of adolescent North Korean refugees. Methods : The participants were 146 adolescents North Korean refugees who attended H High School for North Korean refugees. We divided the subjects into two groups according to the severity of their traumatic experience : the more-traumatic-experience group and the less-traumatic-experience group. Each group performed self-report assessments including an assessment to reveal demographic characteristics, the Traumatic Experiences Scale for North Korean Defectors, the Scale for Ego identity, the Scale for Self-esteem and the Symptom Check-90-Revision (SCL-90-R). Statistical analysis of t-test and multiple regression utilized SPSS 12.0 for Window for comparison between more-traumatic-experience group and less-traumatic-experience group. Results : The prevalence of posttraumatic stress disorder among adolescents North Korean refugees was 37%. The factor with the greatest influence on ego identity was length of time living in South Korea, while, for self-esteem the most influential factor was perception of health. The more-traumatic-experience group had lower self-esteem scores on some subscales of the Scale for Ego identity. They had higher scores on all SCL-90-R subscales than the less-traumatic-experience group. Conclusion : Adolescent North Korean refugees experienced high rates of posttraumatic stress disorder. The more traumatic-experience-group had lower self esteem and poorer ego identity and mental health than the less-traumatic-experience group.
