  • This study described and illustrated the morphology of the sawfly's larva Monocellicampa pruni Wei, 1998 for the first time. Our observations confirmed that its larval biology associated with Japanese plum Prunus salicina Lindl included five instars. The larvae of M. pruni are allied to the general morphology of subfamily Nematinae with a cylindrical body, globose head, 4-segmented antenna, thoracic legs with a distinct claw, and 5 dorsal annulets on abdominal segments I - VIII. The absence of anal prolegs after the first molting shows a distinction with the larvae of genus Hoplocampa.

  • 본 연구에서는 적은 힘으로도 누워있는 환자의 자세를 바꾸어 줄 수 있는 침대 모형을 만들었다. 시중에서 판매되고 있는 변형 환자 침대는 침대의 변형을 수동으로 바꾸거나 침대에 연결되어 있는 구동기로 단순히 환자의 자세를 바꿀 수 있다. 본 연구에서 만들어진 침대는 침대를 다리 하단 / 다리 상단 / 상체 파트로 나누어 따로 또 병렬로 자세를 바꿀 기능을 구현하였을 뿐 아니라, 스마트폰 앱에 의한 제어 구동도 가능하고, 편안한 자세를 이루는 각 파트의 각도를 편리하게 기억시킬 수 있고, 버튼 한번 누름으로 기억된 형태로 구성이 가능하다. 또 누워있는 환자가 관절을 사용하지 않아 굳는 형태를 방지하기 위한 운동 기능이 추가되어 파트별로 운동을 시킬 수 있도록 하였다.

  • Bridging bronchus (BB) is an extremely rare tracheobronchial anomaly. This anomaly is often associated with a sling left pulmonary artery (SLPA) and is diagnosed in infancy or at autopsy. A 29-year-old female patient with previous history of pulmonary tuberculosis was admitted because of persistent fever, cough and sputum. Fiberoptic bronchoscope and chest computed tomography revealed a bridging bronchus and associated atelectasis. The right middle and lower lobe was supplied by a bronchus which originates from the left main bronchus and bridges the mediastinum. There was no anomaly of a left pulmonary artery. Right middle and lower bilobectomy was performed.

  • Two hymenopteran egg parasitoid species, Gryon japonicum (Ashmead) (Scelionidae) and Ooencyrtus nezarae Ishii (Encyrtidae), were emerged from eggs of bean bug, Riptortus clavatus Thunberg (Heteroptera: Alydidae). The former parasitoid is first recorded in Korea. Brief morphological and biological characteristics, and parasitism on R. clavatus eggs are described.

  • This study aimed to classify leg shapes of adult males according to their obesity levels and examine characteristics of each type. The goal was to provide essential data for developing tight-fit pants patterns for adult males. Factors defining leg shapes of adult males were identified as leg horizontal factor, leg vertical factor, ankle thickness factor, and ankle height factor. Leg shapes were categorized into four types: 1) type 1, medium-thick, short legs with thin, medium-height ankles; 2) type 2, medium-thick, long legs with thin, low-height ankles; 3) type 3, thin, medium-length legs with thick, high-height ankles; and 4) type 4, thick, short legs with thick, medium-height ankles. The higher the obesity level, the greater the proportion of type 4, whereas the lower the obesity level, the greater the proportion of types 2 and 3. This suggests that as obesity levels increase, the number of individuals with very thick legs, thick ankles, and shorter legs also increases. Implications of leg shape according to obesity levels in adult males are as follows. First, different age groups require distinct pants patterns. Second, when grading sizes, the variation by body part should be adjusted according to age group. This study is significant as it classifies leg shapes of adult males based on obesity levels and examines characteristics of each type.

  • Morphological characteristics of the cross-bred $F_1$ hybrid between female Paralichthys olivaceus and male Platichthys stellatus were studied. The hybrids showed common biological characteristics of both parents, but showed more morphological similarity to P. stellatus than P. olivaceusin the following biometries: higher ratios of body length to body height (56.3%), head length to snout length (20.6%), and head length to upper jaw length (34.2%). They also showed some significant biometric characteristics similar to P. stellatus, such as ratios of predorsal length (10.5%), prepectoral length (32.2%), preventral length (29.8%), and preanal length (28.0%) to body length. The hybrids had black spots on the dark brownish-green area near the eyes, and they lacked the small bony tubercles that area characteristic of Platichthys stellatus. The hybrids had unique bands: 6~20 bands on the dorsal fin and 5~10 bands on the anal fin that gradually lost their coloration towards the fin margins. The number of fin rays were 60~66 for dorsal fin, 40~51 for anal fin, 18~21 for caudal fin, and 11~12 for pectoral fin. The gills of the hybrids contained 13~18 gill rakers and 73~98 gill filaments. The vertebrae of the hybrids numbered 34~37, with 2~3 vertebrae fused from the start of the caudal vertebrae.

  • The somatic chromosome number of four Korean species of Leontopodium were investigated. The chromosome number of L. leiolepis (2n = 24) is reported here as for the first time. The chromosome number of L. japonicum (2n = 28) is not varied among the 3 populations on the Korean Peninsula, but that condition is different from the previous reports for Korea (2n = 26) and Japan (2n = 21, 26). L. hallaisanense and L. japonicum, both of which are in sect. Nobilia and similar to each other in gross morphology, have the same chromosome number of 2n = 28. On the other hand the chromosome number of Korean L. leontopodioides (2n = 24) is different from that in Russian reports (2n = 26). The chromosome numbers of all Korean species of the genus Leontopodium could be inferred as tetraploid or aneuploid.

  • The purpose of this study was to analyze the change of morphologic pelvis according to age and gender. Pelvis AP(anterior-posterior) projection were taken from 382 individuals (men: 194, women: 188) at the age of twenty and older. We measured four values of pelvis using CR (computed radiological system) including maximum pelvic breadth (MPB), sacral breadth (SB), transverse diameter of pelvic inlet (TD), and distance between femoral heads (DFH). Average (t-test, ANOVA) and Pearson correlation were calculated for comparison. While there was no significant difference of gender in case of MPB, significant differences were observed in SB (men 97.76 mm, women 102.00 mm), TD (men 138.0 mm, women 149.79 mm), and DFH (men 141.94 mm, women 150.39 mm). The DFH values were negatively correlated with the age (men r=-0.280, women r=-0.207). The morphological changes of pelvis were measured high in the men of 50's and in the women of 60's and 70's. The SB, TD and DFH were greater in the women than in the man. As the ages get higher, the deviation of pelvis were gradually increased, which indicates that the morphological changes of pelvis with respect to the age reflects an aging process.

  • This paper proposes a novel approach for the model-based pose matching of a human body using Active Shape Models. To improve the processing time of model creation and registration, we use a skeleton-type model instead of the conventional silhouette-based models. The skeleton model defines feature information that is used to match the human pose. Images used to make the model are for 600 human bodies, and the model has 17 landmarks which indicate the body junction and key features of a human pose. When applying primary Active Shape Models to the skeleton-type model in the matching process, a problem may occur in the proximal joints of the arm and leg due to the color variations on a human body and the insufficient information for the fore-rear directions of profile normals. This problem is solved by using the background subtraction information of a body region in the input image and adding a 4-directions feature of the profile normal in the proximal parts of the arm and leg. In the matching process, the maximum iteration is less than 30 times. As a result, the execution time is quite fast, and was observed to be less than 0.03 sec in an experiment.
