Disposal of a homicide victim by dismemberment is rare, but individual cases are on record in most major medicolegal departments. Recognition of postmortem mutilation may be of importance in the interpretation of certain murders committed by sexual perverts and other mentally deranged individuals and sometimes performed for the sole reason of easier disposal of the body. Postmortem dismemberment is usually readily recognizable as such; The edges of the injuries are dry and lack evidence of bleeding. The joints may be disarticulated without fracture, or the use of an axe or saw may be evident from examination of bones. Parallel horizontal or oblique furrows in the bone surface are caused by skipping of the saw prior to establishing depth. Such patterns on the bone may assist in identifying the particular saw involved. So we report 25 dismembered corpses that autopsied in National Institute of Scientific Investigation. This paper can help in attempting to establish not only the first criminal investigation steps but also the medicolegal approach methods in unidentified and dismembered deaths.

Vasculitis is a heterogeneous group of diseases that destroy blood vessel walls by inflammation. Approximately half of vasculitis cases are idiopathic, but sometimes associated with genetic factors, medicines, chronic infection, autoimmune diseases, and malignancies. Although the mechanism remains unclear, vasculitis secondary to malignancy, also known as paraneoplastic vasculitis, has been reported. It is generally associated with hematologic malignancies rather than solid malignancies and commonly presents as leukocytoclastic vasculitis or polyarteritis nodosa. We experienced a case of leukocytoclastic vasculitis in a patient with hepatocellular carcinoma and membranous obstruction of the inferior vena cava. Here, we report this case with a brief review of literature. (J Rheum Dis 2015;22:322-326)

The status of facilities, management of the experiment, practices, and Science education teaching method in middle school have been investigated. The present status and reasonable management of middle school science education have been grasped from the questionaires. The results are as follows : The reasonable management for expeiments and practices of science education were scanty in the middle school around the urban and rural schools owing to the shortage of facilities and equipments, crowded class, excessive classes, work for teachers, excessive contents of present textbook and insufficience of administrative support etc. The current teaching method of middle school science has emphasized knowledge. This fact does not satisfy the objective of learning due to lack of teaching method. Desirable directions for the improvement of present status of middle school science education were proposed in this paper.

The purpose of this study was to evaluate reliability and validity of the 3-min fast walking field test, and to estimate V0_2max by a equation derived from the test. The subjects were 28 healthy elderly women aged between 60 and 80. A prediction equation was developed by the 3-min fast walking field test. For validation of the reliability and the validity, V0_2max was directly measured by a exercise stress test. And the 3-min fast walking field test, the step test, and the 2-km walking test were conducted. A regression equation for predicting V0_2max was derived from the moving distance, heart rate age, weight and height during the 3-min fast walking field test. And the equation was: V0_2max=0.062934(HR)+0.044271(moving distance)+4.880780(r^2=0.465) For evaluating the reliability of the 3-min fast walking field test, the test-retest technique was employed. The relationship between test and re test was γ=0.607(p<001) and the alpha level was 0.756. For evaluating the validity of the 3-min fast walking field test, the relationships between V0_2max directed measured and the 3-min fast walking field test, the step test, and the 2-㎞ walking test were analyzed. The results showed the relationship between the 3-min fast walking field test and V0_2max directly measured was γ=0.681(p<01). This indicates that, for the prediction of V0_2max in elderly women, the 3-min fast walking field test was more reliable than both of the step test and the 2-㎞ walking test.

For the phenetic analysis of the subfamily Tryphoninae(Hymenoptera:Ichneumonidae), specimens were collected from March of 1988 to September of 1995 in the southem part of Korean peninsula. Specimens were also obtained from various museums and laboratories both in Korea and other counteries. This research utilized about 1000 domestic specimens and 3010 foregin specimens including 10 specimens from North Korea. Phenetic analysis was performed using these specimens (39 genera 39 species)and the following results were obtained. In the cluster analysis, the ward method is more effective than the average linkage method (within group and between group), while the use of total characteristics was resulted in more stable grouping than only quantitative or qualitative characteristics. The cluster and discriminant analyses suggested that the Townes(1969) and Townes et al.(1992)'s system is well fit for the classification of Tryphoninae. For the subfamiliar classification, the analyses of total characteristics by ward method resulted in the most accetable grouping.
