Faculty of Education and Culture and Graduate School of Education, University of Miyazaki, have been implementing a research project for the support of continuity from elementary through junior secondary levels since 2011. This project aims at conducting comprehensive research on the theory and practice of continuity from elementary through junior secondary levels, developing a teacher education programme (pre-service and in-service) based on the research, and pronouncing research outcomes. For the purpose of contributing the research project, this paper intended to identify the trend of previous researches on the continuity from elementary through junior secondary levels in Mathematics Education and to gain suggestions for the programme by reviewing the 63 selected previous research papers in terms of research questions, research methods and outcomes. As a result, the following trends were identified: a) In terms of "teaching contents", the previous researches have proposed a lot of perspectives and concrete ideas on development of teaching contents and lesson designs especially for the domains of "Numbers and calculation/algebra" and "geometry". In addition, they have also developed and practiced some curriculum for continuity from elementary through junior secondary levels. b) In terms of "students", they have identified the characteristics of students' understanding and learning during the transitional period (from 10 to 13 years old) at a certain level. However, it is necessary to research more about their affective dimension. c) In terms of "teachers", although they have proposed some desirable teaching activities, there is a need to implement more comprehensive research. For instance, the points of view on the gap of school/teacher cultures between at elementary and junior secondary levels, the difference of teachers' academic backgrounds should be considered. d) In terms of "context", there is also a need to conduct more researches, for instance, focusing on the influence of examination, the expectation of parents, the perspectives of learning in community etc.

The importance of cohort studies in order to explore diseae causes has been recognized. When a disease is rare, the cohort studies need a long follow-up period, a high budget, and a large number of participants in the target population. A nested case-control study design is proposed as a supplementary study conducted within a cohort, efficiently using the information from the cohort study. In the present paper we explain the sampling design of controls and the methods of data analysis in a nested case-control study. In addition we explain the methods of sample size and power calculation to design the nested case-control study. Further, we introduce some methods for the data with missing values in covariates, and we report the performance assessment from the application of these methods to the nested case-control study data.

Objectives : The aim of this study was to ascertain rates of self-awareness of having contracted hemorrhoids, and to investigate the relationship between life-style and work environment factors to self-awareness of contracting hemorrhoids.###Methods : The subjects were all male employees of company A. Self-awareness of contracting hemorrhoids and factors contributing to self-awareness were determined by self-administered questionnaires.###Results : The questionnaires were distributed to 966 subjects, with 836 questionnaires being returned at the completion of the survey. The rate of contracting hemorrhoids was 32.7%. The most common symptoms were bleeding and pain. We determined that the work environment and self-awareness of contracting hemorrhoids were not significantly related, but that self-awareness of contracting hemorrhoids was significantly related to drinking, large consumption of meat, living environment stress factors, constipation, diarrhea, the custom of using automated cleaning toilets, age, and contract within family factors.###Conclusions : A large number of respondents indicated self-awareness of contracting hemorrhoids. Age, contract within family factors, post-bowel movement cleaning customs, and stress, were all seen as related to contracting hemorrhoids. Half of the subjects among those who contacted hemorrhoids did not consult a doctor. Therefore, we regard consultation with a medical professional as a necessary aspect of occupational health activity. We further suggest this as a part of general life guidance programs in order to prevent the aggravation and recurrence of hemorrhoids.

本調査の目的は,平成20年3月告示中学校学習指導要領の移行措置期間において,中学校第3学年の生徒のグラフを読み取る能力を把握し,新しい中学校学習指導要領の完全実施に向けて指導上の示唆を得ることである.茨城県,愛知県,宮崎県の公立中学校6校に協力を依頼し,中学校第3学年の生徒991名を対象にしてグラフを読み取る能力を調査した.その結果,学習者には,次の2つの誤った判断をする傾向があると考えられた : 「データの一部が省略された棒グラフ」の読み取りにおける「省略グラフの誤判断」.「積み上げ棒グラフ」の読み取りにおける「部分の誤判断」.

This paper presents an asymptotic method of power calculations for likelihood ratio tests in the nested case-control designs with a randomly sampled control per case. It is an extension of the approach described in Self et al. (1992) for proportional hazards models. Our approach here focuses on a simple scenario with 1 : 1 case-control ratio, simple random sampling design, and two independent dichotomous covariates with no interaction effects. The approximation of the noncentrality of the noncentral chi-square distribution for the likelihood ratio statistic is provided. Simulation studies are conducted to examine the accuracy for several parameter values and data configurations. Overall the results suggest that estimates of power using our proposed method are consistent with those of actual power from Monte Carlo simulation. Therefore, the proposed approach can be practically useful in assessing the statistical power for the simple nested case-control design.

There are few epidemiological studies of asymptomatic chlamydial infection among students in non-medical settings with minimal bias and improved accuracy; thus, useful data from screening among students are limited. We aimed to obtain accurate epidemiological information about asymptomatic chlamydial infection among students in non-medical settings. A population-based cross-sectional survey of 10,440 ≥18-year-old asymptomatic students who volunteered for a urine screening test for chlamydia was conducted. The prevalences of asymptomatic infection were 9.5% for women and 6.7% for men. Multivariate analysis revealed the risk factors to be a lifetime history of ≥4 sexual partners for women (odds ratio [OR] 3.17) and inconsistent condom use for men (OR 4.18). For both sexes, younger age at first intercourse was associated with a higher rate of inconsistent condom use. This study produced accurate epidemiological information on asymptomatic chlamydial infection. These results may contribute to the establishment of preventive countermeasures against such infection.

In epidemiological studies there are numerous challenges to finding an appropriate experimental design for studying the relationship between an exposure and a disease. A number of designs for observational studies have been investigated; the cohort study and the standard case-control study are the primary types. The nested case-control study design combines features of both. In the nested case-control study some information is available for all cohort members and additional information is obtained using a case-control design based on incidence density sampling rather than cumulative prevalence sampling. To get higher efficiency, it is important to effectively use the information already available on cohort members when we choose the controls. The counter-matched design is one such method, which chooses the controls based on exposure status or a surrogate measure of the exposure. It has high efficiency to estimate the effect of the exposure or interaction between the exposure and another risk factor. Unfortunately, there are few examples of application of this design to real situations. To encourage use of the counter-matched design, we describe the basic concept and statistical methods underlying the method. Some examples are presented to illustrate how to implement the design. We also propose some extensions to provide a more flexible sampling design.
