Disciplines and areas

Clinical Laboratory Sciences

In recent years, there have been drastic changes in health sciences, such as the advent of genomic and regenerative approaches to medicine. Clinical laboratory examinations are indispensable for the development of diagnoses and treatment in these areas. These rapid changes have been accompanied by increasing demand for laboratory scientists who can flexibly deal with clinical laboratory examinations, which are continuously advancing in the degree of specialization. The clinical laboratory sciences program aims to nurture highly skilled laboratory scientists who can understand biological information based on the foundation of education and research acquired in the Master’s program, can address changes in health services, and can become teachers, researchers, and leaders. Students will learn to develop the latest examination techniques and examination devices. Students will also conduct etiological and pathological analyses employing biochemical analysis methods for biological substances at a molecular level, quantitative gene amplification methods, morphological examination methods, and cytological diagnostic methods. Finally, students will conduct research (e.g., biological analysis) from the perspectives of environmental physiology and psychosomatic medicine.

The main subjects in this area are: advanced theory of clinical laboratory sciences, clinical laboratory sciences practice I (examination implementation studies), clinical laboratory sciences practice II (molecular pathological analysis studies), clinical laboratory sciences practice III (clinical laboratory sciences and physiology), and special research in clinical laboratory sciences.

Rehabilitation education science

The scope for research in rehabilitation education science is training and educating students studying toward a degree, entry-level therapists who have recently graduated, and instructors who provide instructions to such students and entry-level professionals. Related research aims to scientifically elucidate the characteristics of education for therapists engaged in various areas of rehabilitation medicine as well as effective intervention methods. In the Master’s program (rehabilitation education science) of the Graduate School of Health Sciences, research is conducted to deepen the understanding of students, entry-level therapists, and instructors.

As the same time, it is beneficial for students majoring in rehabilitation therapy science to deepen their understanding of rehabilitation education science regardless of whether or not they select rehabilitation education science as the main target of their research. In other words, research efforts in the department of rehabilitation therapy science provide many opportunities to work with therapists, either as researchers or as subjects. Knowing what kind of education participating therapists have undergone and anticipating what kind of education potential participating therapists may have are important in interpreting research results or setting up future research plans. In advanced theory of rehabilitation therapy science I, which is a class required for participation in the Doctor of Philosophy program, students acquire the latest knowledge pertaining to the standardization of clinical skills in the education of physical therapists. Students also learn to evaluate the reliability, adequacy, and effects of objective structured clinical examinations (OSCEs) and hold in-depth exchanges of ideas on the future orientation of related education methods. These pedagogical tools are tailored for each type of student, from entry-level physical therapists to clinical practice instructors, through lectures and discussions. In rehabilitation therapy science practice I, students aim to verify the effectiveness of specific education methods through practical exercises. Efforts to clarify these educational methods are developed through clinical skill education using OSCEs for physical therapists. Moreover, thoughts are developed on the details of education for training the instructors who conduct clinical practicum activities for the purpose of effectively implementing such activities. A new educational instruction system, in which collaboration between university teaching staff and practicum instructors is strengthened, is also being considered.
