The study was carried out on 1328 pupils aged of 6-15 years in Xuan Bac primary and Xuan Ngoc secondary school, Xuan Truong district, Namdinh province in 2002 ( males were 69, females were 638). The results showed some anthropometric measurements and clinical examinations. The following conclusion have been drawn:- Physical status: The anthropometric of Xuan Bac and Xuan Ngoc school children were considerably higher than those of 1975 Vietnamese biological constant and those of Thai binh province in 1995; but these indices were lower than index of Duong Nghiep Chi in 2001. – Morbidity: The general morbidity rate:38.62%. Four commonest disease in the Xuan Truong School (6-15 years old) were dento-oral disease (28.46%), ear-nose-throat diseases(7.75%),goiter diseases (2.43%) and myopia (2.03%)

To prevent protein-energy malnutrition in elderly inpatients with dysphagia, weexamined the current meals for them in detail. The thickeners seemed to be a ploblem. Changes of viscosity over time and temperature were reduced when a starch thickener was changed to a xanthan gum thickener. When a gelatinizer was added to soft meals to allow cutting into shape, etc., the meals looked better were less sticky, more cohesive, and easier to eat. Thus, the smooth texture required of meals for dysphagia patients was obtained. When conventional mixed meals were changed to soft meals, there was an improvement of appearance and the meals became more palatable.The change of food intake after these improvements was investigated in five inpatients who had difficulty in swallowing. Food intake was increased in four of these five patients after these improvements, suggesting that their appetite might have been increased by improvement of the appearance and palatability of their meals. We will continue making improvements of these meals in hopes that patients can eat solid food again as early as possible.

The link between micro- and macro-parameters for radiation interactions that take place in living biological systems is described in this paper. Meanwhile recent progress and development in microdosimetry and nanodosimetry are introduced, including the methods to measure and calculate these micro- or nano-parameters. The relationship between radiobiology and physical quantities in microdosimetry and nanodosimetry was presented. Both the current problems on their applications in radiation protection and radiotherapy and the future development direction are proposed.

Taiki is a kind of fundamental vital energy filling the upper aspect of the body, and it can fall because of stress, heavy labor, diarrhea, excessive intake of drugs for regulating the flow of vital energy, or extreme deficiency in vital energy.We report the case of a 39 year old female patient who complained of dyspnea, psychic enervation, and other symptoms of falling taiki from the upper aspect of the body, caused by taking a cathartic drug (mashiningan) for constipation, while being treated for agitation and emotional incontinence. Shokanto improved this state of falling taiki from the upper aspect of the body.

Oriental medicine explains that Kikyo (deficiency of Qi) is an exhausted state of the human body's energy. Hence a lack of energy state could be equal to a state of low metabolism. It would affect any blood test. Kikyo-scores were evaluated in 333 new patients who had visited our clinic within a 13-month period, and their blood samples were collected on the same days. A chi-square test was done with the Kikyo cases, indicating points of 30 and above of Kikyo-score, and patients who indicated lower than standard levels in their blood tests. A relationship between Kikyo, and points lower than normal chemical screening test values was proved (p<0.0001). Forty-nine percent of Kikyo-patients were under normal limits, but the positive predictive ratio was85%. We have to recognize it is an exhaustive Qi state we see, when chemical screening data values are low.

Traumatic injury to the eye can occur due to various causes, most of which are avoidable. Here we report three cases of intrastromal corneal foreign bodies (FB) which required surgical removal. Most corneal FBs are removed easily at the slit lamp, however, these cases required surgical intervention due to the mechanism of which the FB penetrated into the stroma. Although the mechanism of injury was similar, with all three cases occurring at high velocity, we observed that the entry and level of penetration differed in each case. In the first case, the corneal FB penetrated the cornea and was embedded in the anterior stroma, whereas in the second case, the FB was embedded in the posterior stroma, but with an intact endothelium. In the third case, the FB caused a full thickness, self-sealed laceration wound but remained embedded in the stroma. Through further evaluation, we noted that several factors contribute towards the severity of the injury, namely, anatomy of the cornea, area affected, shape, size, mass and velocity of the object. We speak in depth about the mechanism of injury and physics associated with these injuries and why the penetration differed in each case.

According to the World Health Organization (WHO), the basic sciences to support the human health are chemistry, physics and informatics. Chemistry is the base of pharmacy. Physics is the base of medical instruments and equipments (MIE). The diagnosis and therapy of diseases are relying on informatics. Therefore, as the fusion results of physics and medicine, medical physics is the creative source science of MIE. Among all diagnosis tools, medical imaging devices are the fastest-developed and the most-complicated MIE since Roentgen discovered X-ray which was quickly used in medical diagnosis in 1895. Among all treatment tools, the radiotherapeutical devices are the most-widely used and the most effective MIE for tumor treatments since Mrs. Courier found the nature radiation isotope Radium at the end of 19th century and began to use it in tumor therapy. Although the research and development (R&D) of so-complicated MIE need many subjects of science and engineering, the kernel science is medical physics. With the results of more than 50 years' development in developed countries, medical physics has defined its own field, which is the medical imaging physics and the radiotherapeutical physics. But, the definition has been expanded to be wider and wider. Therefore, we should pay more attention to the establishment of Medical Physics in China. In order to develop medical physics in china, the bases of R&D and clinical practice should be also built.

The energy expenditure, food consumption and anthropometry of two groups of Hull women are described. The group occupying the highly productive drained margins of the Haeapugua Swamp at Weinani have significantly higher intakes of energy and protein than those at Heli on the Paijaka Plateau. However, both groups of women expend similar amounts of time and energy in agricultural activities. The differences are explained by the contrasting quality of agricultural land at each place. Production per hectare at Heli is only around half of that at Weinani. It is concluded that the nutritional health of Heli women is compromised. This is probably the cause of the significantly lower mean birthweights of children born to women living on the Paijaka Plateau.
