  • Primary segmental volvulus of the small intestine is not associated with malrotation, malfixation of the midgut, nor other primary small bowel lesions such as small bowel tumors. This entity is known to be more prevalent in adult and in certain global areas associated with particular diet habits. There have been very few reports in neonates, but not in this country so far. The author reports two cases of primary segmental volvulus. Case 1 was a septic 4-day-old girl with hematochezia due to jejunal volvulus with partial necrosis and panperitonitis. Resection of the segment and Bishop-Koop enterostomy were successful. Case 2 was a 3-day-old boy, who had ileal volvulus with ultra-short length of ileal atresia, probably due to intrauterine segmental volvulus. Limited resection of the atresia and spreading of the mesenteric base were enough to recovery. The rarity of the pathognomonic findings and limitation of the diagnostic workup due to rapid progression limit early diagnosis and good survival rate in this particular condition.

  • The STL or Stereolithography format, established by 3D systems, gathers the geometric data of the model in a number of triangular surfaces. It can be in ASCII or binary format, and is a de facto standard in the Rapid Prototyping (RP) world. RP has developed greatly over the last ten years. In particular, improvement in materials has meant greater part accuracy and strength, which in turn has increased the range of functional applications. Future applications of RP will focus on rapid tooling and direct manufacturing. Direct manufacturing in particular may see much benefit from the incorporation of color into models. For color RP, besides designing new hardware to add color into the prototypes, it is necessary to redefine the CAD software for adding and accurately positioning color onto the model. STL cannot effectively store this kind of information. Among the existing data file formats, VRML is an acceptable one that is complimentary to existing RP processes. This paper acts as a review to discuss several methods of using VRML for coloring model data. This paper will also discuss the problems occurred in coloring the layer contours of the RP model.

  • The augmented visualization of analysis results can play an import role as a post-processing tool for the modeling & simulation (M&S) technology. In particular, it is essential to develop such an M&S tool which can run on various multi-devices. This paper presents an augmented reality (AR) approach to visualizing and interacting with M&S post-processing results through mobile devices. The proposed approach imports M&S data, extracts analysis information, and converts the extracted information into the one used for AR-based visualization. Finally, the result can be displayed on the mobile device through an AR marker tracking and a shader-based realistic rendering. In particular, the proposed method can superimpose AR-based realistic scenes onto physical objects such as 3D printing-based physical prototypes in a seamless manner, which can provide more immersive visualization and natural interaction of M&S results than conventional VR or AR-based approaches. A user study has been performed to analyze the qualitative usability. Implementation results will also be given to show the advantage and effectiveness of the proposed approach.

  • As health and well-being become a global trend, the younger generation is focusing on the balance between work and leisure time and they are interested in sports activities as well as a cultural life. In addition, the range of sportswear is expanding, so that athleisure fashion is getting into daily lives. In particular, consumer groups in the sportswear market are beginning to change since generation Z consumers are more and more interested in sportswear and their needs are also growing of health and functional of sports wear. It's a global trend that athleisure fashion market is growing, which combines professional athletic wear with fashion. As the number of women who enjoy sports and leisure in their spare time, the consumer pattern in the sports wear market is also expanding to female customers. However, most sports functional wears were focused on male consumers, so that functional inner-wears are mostly made for both sexes, which mean the functional inner-wears are produced without considering the physical characteristics of men and women and with not enough size division ending up not suitable for professional athletes. In particular, female professional athletes need functional inner-wear that fits the characteristics of the sport because they are not only different in physical condition and they are also using different muscles for different movements. Therefore, functional inner-wear needs pattern development and size system setting considering the body shape and athletic movement of female professional athlete.

  • In practical wireless relay communication systems, non-destination nodes are assumed to be idle not receiving signals while the relay sends messages to a particular destination node, which results in reduced bandwidth efficiency. To improve the bandwidth efficiency, we relax the idle assumption of non-destination nodes and assume that non-destination nodes may receive signals from sources. We note that the message relayed to a particular node in such a system gives rise to interference to other nodes. To study such a more general relay system, we consider, in this paper, a relay system in which the relay first listens to the source, then routes the source message to the destination, and finally produces interference to the destination in sending messages for other systems. We obtain capacity upper and lower bounds and study the optimal method to deal with the interference as well as the optimal routing schemes. From analytic results obtained, we find the conditions on which the direct transmission provides higher transmission rate. Next, we find the conditions, by numerical evaluation of the theoretical results, on which it is better for the destination to cancel and decode the interference. Also we find the optimal source power allocation scheme that achieves the lower bound depending on various channel conditions. We believe that the results provided in this paper will provide useful insights to system designers in strategically choosing the optimal routing algorithms depending on the channel conditions.

  • Genetic testing has been generalized for the diagnosis of diseases and is an important method of research with advances in the life sciences. In particular, we should give better attention to the genetic test for a fetus. Because the fetus has no autonomy, ethical and social issues can arise. Therefore, appropriate genetic counseling is needed for parents to be informed with the characteristics, natural progress, and possible treatment of a genetic disease, prior to the prenatal genetic test. Physicians should also inform parents how a particular genetic risk factor relates with the likelihood of a disease, in order to assist the parents in making the best decision. Furthermore, the current law for prenatal genetic testing should be approached rationally.

  • Traditional medicine in Asian countries show similarity according to geography, building up their own medical tradition upon indigenous cultural background. Mongolian medicine, in particular, displays district fusion of several medical systems accepted from neighboring countries adding to their traditional system. Those are Mongol Dhom medicine, acupuncture and moxibustion medicine, medicine of "Four Medical Tantras (四部醫典)", and combined system of Mongolian and biomedicine. Compared to East asian medicine, this is a different kind of diversity or hybridity resulting from idiosyncrasy of nomadic culture. Each current of Mongolian medical tradition has its own origin of historical backdrop. Mongol Dhom originated from ancient nomadic life, and medicine of "Four Medical Tantras (四部醫典)" was formed along with transmission of Tibetan Buddhism. Acupuncture and moxibustion is directly related to Chinese medical tradition, however, moxibustion is also referred to be regional origination. Lastly, biomedicine was transplanted during the modernization era, encouraging scientific approach toward Mongolian traditional medicine and producing combined medical practice. It is effective to derive each particular aspects of Mongolian medicine and analyze its specificity, in order to properly understand current Mongolian medical system. This paper aims at discovering socio-cultural meanings of each current and their nomadic feature beneath the diversity.

  • On January 1, 2005, the Korean Ministry of Environment put into operation a comprehensive program, so called 'Blue Sky 21' project, for the improvement of air quality in greater Seoul metropolitan area. This program was legally based on the 'Special Act on Metropolitan Air Quality Improvement' for Greater Seoul area, which was established in 2003, and should be updated every 10 years. The principal objective of this program is to improve the air quality in Seoul and surrounding area by 2014 to the levels of air quality in Tokyo and Paris, with particular emphases on reducing the concentrations of nitrogen dioxide and $PM_{10}$. Any regulation of the emission of toxic air pollutants in general, and $NO_2$ and $PM_{10}$ in particular, should be based on human exposure levels and consequential health effects. In this article, the contents and feasibility of the special program were critically evaluated with respect to the reduction of health risks. Important issues for improving not only air quality but public health are discussed, and future requirements for the success of the special program are suggested.
