The developmental disorder(intellectual disorder(ID) and autism spectrum disorder(ASD)) can severely impair a patient's ability to communicate and socialize. So they require physical management techniques, pharmacologic agents, and general anesthesia more than the normal at the dental clinic. The behavior therapy is a kind of the psychotherapy and is applied to the patient with behavioral problems. Seoul Dental Hospital for Disabled(SDHD) set up the Dental Behavior Clinic for the patients with developmental disorder and treated 32 patients with ID or ASD, blind. 18 patients were treated according to the ordinary plans, 14 patients stopped the treatment by different reasons. The various results of the treatment were produced by the kind or severity of the diseases, age and cooperation of the patients and the caregivers. Especially, the behavior therapist helped to figure out the characteristics of the patients and to make individualized treatment plans. In the future, it will be necessary to treat more patients and to make the dental behavior therapy objectify. And through the dental behavior therapy, it will be expected that the patients will become more cooperative to the dental clinic and can receive regular check-up peacefully, reducing the frequency of the general anesthesia.

The Ovarian developmental phases of the reproductive cycle of Rapana venosa can be classified into five successive stages by histological study: early active stage (September to February), late active stage (December to April), ripe stage (March to July), partially spawned stage (May to August), and recovery stage (June to September). To understand the characteristics of nutrient storage and utilization in the digestive gland cells with ovarian developmental phases, we examined the digestive gland - which is the major nutrient supply organ associated with ovarian development of the female purple shell - by biochemical methods. Total protein contents in the digestive gland tissues increased in March (late active stage) and reached the maximum in May (ripe and partially spawned stages), and then their levels sharply decreased in July (partially spawned and recovery stages). Total lipid contents in the digestive gland tissues reached the maximum in January (early active stage). Thereafter, their levels rapidly decreased from May (ripe and partially spawned stages) and reached a minimum in July (partially spawned and recovery stages). The total DNA contents did not significantly change regardless of the different developmental stages of the ovary. However, it was also found from biochemical analysis that changes in total RNA content follow the same seasonal cycling to protein. These results indicate that the digestive gland is an important energy storage and supply organ in purple shells, and that the nutrient contents of the digestive gland change in response to gonadal energy needs.

본 논문에서는 발달장애 아동의 교육 및 치료에 있어서 감각, 인지훈련을 효과적으로 할 수 있는 에듀테인먼트 플랫폼을 제시한다. 이를 위해 임베디드 하드웨어를 개발하고 여기서 재생할 콘텐츠를 제작하기 위한 저작도구, 학습 결과를 확인할 수 있는 관리도구, 학습 상황을 실시간으로 모니터링하는 도구를 개발하였다. 발달장애 아동의 특성을 관찰 분석하여 개발한 하드웨어는 주의집중을 위한 감각훈련을 집중적으로 할 수 있도록 시각, 청각, 촉각 등의 자극을 제공한다. 이와 함께 개발한 소프트웨어는 특수교사 이외의 비전문가도 쉽게 교육용 콘텐츠를 만들고 학습 현장이외에서도 학습상황을 볼 수 있도록 하는 기능을 제공한다. 또한, 학습한 결과를 다음 학습단계로 적용할 수 있도록 이를 보관하고 살펴 볼 수 있는 기능도 제공한다. 이를 통해 시간, 장소의 제한 없이 효과적으로 반복 학습을 수행이 가능하다. 개발한 플랫폼을 직접 교육현장에 적용해봄으로써 주의집중과 학습 능력을 높이는데 효과가 있음을 알 수 있었다.

The ultrastructure of the secretory granules of the submandibular gland was examined in the Korean spider shrew, Sorex caecutiens, lesser white-toothed shrew, Crocidura suaveolens and big white-toothed shrew, C. lasiura. The mucous and serous acinar granules of S. caecutiens with a border of the lucid corona differed from those of C. suaveolens and C. lasiurar with a dense lateral border. The mucous acinar granules of C. lasiura with several bands producing a variety of patterns in the matrix were similar to those of C. suaveolens. The serous acinar granules of C. lasiura had a homogenous pale center surrounded by minute dense specks or had an unusual substructure showing a geometric pattern according to the inclusions in the pale matrix of the granules. This is the first report of an unusual substructure showing a geometric pattern of the serous acinar granules of C. lasiura. The myelin-like body was observed in the granular duct cell of the three species of shrew. The myelin-like body of S. caecutiens with layers of unit membranes was different from that of C. suaveolens and C. lasiura with paired membranes. Therefore, the layers composing of the paired membranes of the myelin-like body might be one of the characteristics of Crocidura.

This study evaluated a sexed sperm ability to produce embryos by flow cytometer. Hanwoo bulls sperm were separated to X and Y sperm via Hoechst 33342 stained with near UV laser or performed the pre-sorted without near UV laser beam in flow cytometry. Pre-sorted sperm had significantly higher viability ($84{\pm}1.15%$, $p$<0.05) compared to other sorted groups in frozen-thawed semen. For fresh semen, pre-sorted sperm had the higher viability ($79{\pm}3%$, $p$<0.05) than those of the X and Y sperm ($44.7{\pm}1.67$ and $41.7{\pm}1.2%$) separated by differences of DNA content. On the other hand, pre-sorted and X sperm sorted according to differences in DNA content had significantly higher viabilities ($24.3{\pm}1.2$ and $25.7{\pm}0.9%$, $p$<0.05) compared to that of the sorted Y sperm ($13.7{\pm}1.2%$) in the hypoosmotic swelling test. The proportion acrosome reaction in the sorted X sperm was higher ($55.0{\pm}1.7$ and $45.0{\pm}1.5%$) than those of the sorted Y-sperm ($32.3{\pm}0.9%$, $p$<0.05). However, the sperm morphologies of the sorted groups were not significantly differences. In conclusion, the sex-sorting procedure by flow cytometry affected some characteristics of Hanwoo sperm. Further study is needed to determine the optimal procedures to enhance male and female embryos and sorting accuracy.

Therapeuticre rehabilitation of young children has often included the use of walker as mobility aids. Traditional walkers have four vertical legs, a horizontal bar in front of child, and horizontal bars on either side which also serve as hand grip. Child pushes it. It is called 'anterior walker'. 'Posterior walker' have been introduced which the child pull along behind himself during ambulation. The purpose of this investigation was to compare specific gait characteristics of children with developmental disability, while they ambulated with anterior and posterior walker. Using the posterior walker, specific gait characteristics improve than using anterior walker.

We review discharge characteristics of fluorescent lamps having noncircular cross sections. The developmental and theoretical history of noncircular cross-section lamps is summarized chronologically. In particular, discharge characteristics of noncircular cross-section lamps will be summarized and analyzed including plasma contraction, electron temperature, and ambipolar diffusion loss, which might give us some insights into the way to develop more efficient and uniform flat fluorescent lamps, which have recently arisen as a new light source of large-size backlight units for LCD TV applications.
