This study aims to deduce the effective collaborative process of architectural design process based on the specific pavilion design case. The study schematizes the collaborative procedure which is generated at the early stage of design process, analyzes the decision support system and suggests the method for reaching a compromise.Finally, this study suggested collaborative process method of architectural design and provided the basic concept that can be used for the similar projects. Keywords : Collaborative Design, Design Process

In this study, the frequencies and types of questions about LIFE areas of the Science Curriculum of elementary school students were investigated through in-depth interviews with twelve 4th and 5th graders. The results of the research can be summarized as follows: (1) In conjectural question, the proportions of 'object exploration question' and 'object verification question' were high in all of the 4th graders and the students of low achievement level. (2) The numbers of causal questions generated by the 4th graders were much higher than those of the 5th graders. (3) The frequencies of the predictive, methodological, applicative questions were very low both in 4th and 5th grade students. (4) The numbers of conjectural questions were more in all students except the low achievement level of 4th graders at not-yet-taken contents than at already-taken ones. (5) The numbers of causal questions were more in all students except the low and middle achievement levels of 4th graders at not-yet-taken contents than at already-taken ones. (6) The numbers of the predictive, methodological, applicative questions of the 4th graders were more at not-yet-taken contents than at already-taken ones, whereas opposite trend in the 5th graders. (7) The numbers of students' curriculum-related questions were more in all students except the low and middle achievement levels of 4th graders at not-yet-taken contents than at already-taken ones. (8) As ways for solving or seeking answers about questions, the 4th graders suggested methods of consulting experts or teachers (23.9%), internet searching (21.6%), and books or science-related encyclopedia (20.3%), while the 5th graders suggested the internet searching (36.5%), consulting experts or teachers (24.8%), and books or science-related encyclopedia (17.7%). Based an these results, we suggest several ways for improving the question-posing abilities of the students and adequate use of students' questions in the process of science teaching learning.

Vibrio cholerae is mainly known to cause gastrointestinal infection after seawater exposure or raw seafood intake. It is rarely reported to cause cellulitis or sepsis, but threre has been no known case after acupuncture. Herein, We report a 56-year-old cirrhotic patient of non-O1, non-O139 Vibrio cholerae septicemia caused by cellulitis of both lower extremities after acupuncture.

Cerebral small vessel disease is the most important cause of lacunar infarction (LI) and intracerebral hemorrhage (ICH). It is generally postulated that, in its early stages, the vascular lesion engenders vessel wall fragility and ICH. But if rupture dose not occur, segmental vessel occlusion evolves, producing LI. It may be a common aging phenomenon that is exacerbated by hypertension and diabetes mellitus. This study was performed to evaluate risk factors of LI and ICH. We reviewed retrospectively the medical records of 690 patients (254 LI, 436 ICH) with stroke who were admitted to Keimyung University Dongsan Medical Center from January 1995 to December 1998. The major risk factors including age, sex, hypertension, diabetes mellitus and several minor risk factors were analyzed in these patients. Older age (p<0.01), male sex(p<0.01), hypertension with treatment(p<0.01), hypertension with long duration(p<0.01) and hypertriglyceridemia(p<0.01), cigarette smoking(p<0.01) were significantly more frequent in LI. Younger age(p<0.01), female sex(p<0.01) and hypertension without treatment(p<0.01), hypertension with short duration(p<0.01) were more frequent in ICH. The prevalence, duration and treatment of diabetes mellitus were not different between these two groups. This study show that the age, sex, treatment of hypertension, duration of hypertension and cigarette smoking seem to be significant risk factors between LI and ICH.

It is known that the analytic operator-valued Feynman integralexists for some ``potentials'' which are so singular that theymust be given by measures rather than by functions.

In particular, maternal prostacyclin (PGI2) is critical for embryo implantation and the action of PGI2 is not mediated via its G protein-coupled membrane receptor, IP, but its nuclear receptor, peroxisome proliferator-activated receptor δ (PPARδ). Recently, several studies have shown that PGI2 enhances blastocyst development and/or hatching rate in vitro, and subsequently implantation and live birth rates in mice. However, the mechanism by which PGI2 improves preimplantation embryo development in vitro remains unclear. Using molecular, pharmacologic and genetic approaches, we show that PGI2-induced PPARδ activation accelerates blastocyst hatching in mice. mRNAs for PPARδ, RXRs (heterodimeric partners of PPARδ) and PGI2 synthase are temporally induced after zygotic gene activation and their expression reaches maximum levels at the blastocyst stage, suggesting that functional complex of PPARδ can be formed in the blastocyst. Carbaprostacyclin (cPGI, a stable analogue of PGI2) and GW501516 (a PPARδ selective agonist) significantly accelerated blastocyst hatching but did not increase total cell number of cultured blastocysts. Whereas U51605 (a PGIS inhibitor) interfered with blastocyst hatching, GW501516 restored U51605-induced retarded hatching. In contrast to improvement of blastocyst hatching by PPARδ agonists, PPAR antagonists significantly inhibited blastocyst hatching. Furthermore, deletion of PPARδ at early stages of preimplantation mouse embryos caused delay of blastocyst hatching, but did not impair blastocyst development. Taken together, PGI2-induced PPARδ activation accelerates blastocyst hatching in mice.

<P><B>Abstract</B></P><P>Fabrication of organic field‐effect transistors (OFETs) using a high‐throughput printing process has garnered tremendous interest for realizing low‐cost and large‐area flexible electronic devices. Printing of organic semiconductors for active layer of transistor is one of the most critical steps for achieving this goal. The charge carrier transport behavior in this layer, dictated by the crystalline microstructure and molecular orientations of the organic semiconductor, determines the transistor performance. Here, it is demonstrated that an inkjet‐printed single‐droplet of a semiconducting/insulating polymer blend holds substantial promise as a means for implementing direct‐write fabrication of organic transistors. Control of the solubility of the semiconducting component in a blend solution can yield an inkjet‐printed single‐droplet blend film characterized by a semiconductor nanowire network embedded in an insulating polymer matrix. The inkjet‐printed blend films having this unique structure provide effective pathways for charge carrier transport through semiconductor nanowires, as well as significantly improve the on‐off current ratio and the environmental stability of the printed transistors.</P>
