Ch`eng jiong(程逈: 沙隨, 南宋人)`s The old divination method of the Yijing(周易古占法) is based on Shao K`ang-chieh(邵康節)`s Theory of Antedates Heaven(先天論), and make reference to divinations of Ch`un-ch`iu Tso-chuan(春秋左傳) and Guoyu(國語), however his explication is very wrong, now I try to refute. 1. Ch`eng jiong(程逈): T`ai-chi(太極, the Supreme Ultimate) have no direction and no body, such is spirit(神) and principle(理). Cheong yong(丁鏞)`s refutation: T`ai-chi in the Yijing is nothing but an imitation of the Universe. 2. Ch`eng jiong: Two Symbols(兩儀) are the first lines of C`ien(乾) and K`un(坤), three counts(三變) of Da yan(大衍). Four images(四象), in the same manner, are the first and second lines of C`ien and K`un, six counts(六變) of Da yan. Cheong yong`s refutation: Liang yi(兩儀) is two symbols, not two properties. Four images are an imitation of four seasons. 3. Ch`eng jiong: The eight primary trigrams(八卦) are three lines of C`ien and K`un, nine counts(九變) of Da yan. The hexagram(重卦) is mixed double with eight primary trigrams. Cheong yong`s refutation: It is difficult to understand how such a baseless fiction could have arisen. The eight primary trigrams are eight emblem.

To achieve the ULSI goals of higher density and greater performance, STI(shallow trench isolation)-CMP(chemical mechanical polishing) process has been attracted. Recently, the direct STI-CMP process without the conventional complex reverse moat etch process has established by using slurry additive with the high selectivity between SiO2 and Si3N4 films for the purpose of process simplification and in-situ EPD(end point detection). However, STI-CMP process has various defects such as nitride residue, torn oxide and demage of silicon active region. Also, it was difficult to assure the suitable process margin in the STI-CMP process. To solve these problems, in this paper, we discussed to determine the control limit of process, which can entirely remove the oxide on nitride film from the most area of high density as reducing the damage of dense moat area and minimizing dishing effect in the large field area. We, also, evaluated the wafer-to-wafer thickness variation and the day-by-day reproducibility of STI-CMP process after repeatable tests.

Background : The amount of pesticide to be produced and consumed have rapidly growed in Korea and the evidences for pesticide intoxication to human body, natural environment and consumers have evoked. But the studies concerned to pesticide intoxication are inactive. So, we conducted this study about the determinants of awareness and performance for prevention of pesticide intoxication. Methods : The study conduced during the period from July to August 2007 with population consisted of 111 farmers. The toolkit was produced through referencing previous studies. Data analysis was performed with t-test, ANOVA and multiple linear regression analysis using SPSS 14.0K program. Results : The mean awareness score was 3.07 ± 0.75, the mean of total performance score was 2.72 ± 0.69, mean of subtotal performance score for keeping safety guideline was 2.72 ± 0.69 and mean of subtotal performance score for wearing protective equipments was 2.43 ± 0.83. Awareness score was associated with sex, age and family income. Female, older people and people with high income were tend to show low awareness score. Performance score was associated with sex, family income and educational level. Female, people with low education and high income were tend to show low performance score. Conclusion : We concluded that educational effort for noticing the harmful affects of pesticide, the importance of keeping safety guideline and wearing protective equipments to farmers especially female, older people, people with low education and high income were significant factors for prevention of pesticide intoxication.

The enzyme, squalene synthase, represents a branch point in the isoprenoid pathway capable of diverting carbon flow specifically to the biosynthesis of phytosterol and Triterpenoid. Transgenic Eleutherococcus senticosus plants were prepared by introducing the genes for squalene synthase derived from Panax ginseng (PgSS1), hygromycin phosphotransferase (HPT) and green fluorescent protein (GFP) through Agrobacterium-mediated transformation. Establishment of transgenic plantlets were confirmed by the presence of PgSS1 and HPT bands in the genomic DNA preparation using a PCR method and a Southern blotting. In addition, expression of the introduced GFP DNA was confirmed by observing green fluorescence of GFP from the embroyos. In the in vitro analysis of the PgSS1 enzymatic activities the transgenic plants showed to have 1.5 to 3 times higher than wild type plant, indicating that the PgSS1 genes was well over-expressed in the transgenic plants. Especially the PgSS1 acivities of embroyogenic cell was 120 times higher than those of plantlet.

The expression of the transforming growth factor(TGF)-β_2 and ·β_3 was studied in the eye of fetal rats by immunohistochemistry. The results obtained were as follows. The TGF-β_2 and·β_3 expressed in almost all parts of the eye, exhibited the localization in the same areas as well as the localization specific to each isoforms, which indicated the roles of TGF-β_2 and TGF-β_3 were partly dependent on each other. TGF-β_2 showed the characteristic expression pattern in neuroepithelial layer of retina and les cell. TGF-β_3 showed characteristic expression in pigment layer of retina as well as in lens cell. TGF-β_2 exhibited strong and characteristic expression pattern and seemed to have more important role than TGF-β_3 in eye formation. In summary, the expression of TGF-β_2 and·β_3 in the development of the eye was observed in almost all parts, such as iris, lens, retina, and aqueous humor and seemed to play a role in the formation of eyes at fetal life.

Background: For effective education of social medicine, new and more efficient means of education are needed because social medicine consist of diverse background academics . Metohods: Workshop based lecture was carried out twice in social medicine class for medical students and was assessed with questionnaires survey. Results: Half of the students were satisfied with workshop-based learning and required more discussion time and pre-information. Conclusions: With some improvements, workshop-based adult learning method is expected to bring effectiveness in social medicine education.

Subacute combined degeneration is a metabolic disorder of the spinal cord caused by vitamin B12 deficiency. A 72-year old man was admitted with weakness and tingling sensation of the bosh upper extremities. 9 years ago, he was diagnosed as having stomach cancer. So total gastrectomy with splenectomy was done at that time. The complete blood cell counts and morphology revealed megaloblastic anemia. Nerve conduction velocity study(NCV), electoromyography(EMG) and somatosensory evoked potentials(SEP) showed diffuse sensorimotor peripheral neuropathy. Magnetic resonance imaging(MRI) showed an increased T2-weighted signal, mild decreased T1-weighted signal, and slight contrast enhancement of the posterior columns of the cord in the cervical and upper thoracic spinal region. He was treated with vitamin B12 supplements and improved gradually. If abnormal sensation and muscle weakness was developed after gastrointestinal surgery, subacute combined degeneration should be considered in the differential diagnosis. We describe MRI findings of a typical case of subacute combined degeneration, which was induced by total gastrectomy.

As the device geometry shrinks to the deep submicron region, chemical mechanical polishing(CMP) planarization become a more essential technique of advanced ULSI process. Also, CMP process was required for the global planarization of inter-metal dielectric(IMD), inter-level dielectric(ILD) layers and interconnections with free-defect. Especially, the complete global planarization of IMD, ILD and interconnections can be achieved only with the CMP process. However, as the IMD and ILD layer gets thinner, several problems were found in the CMP process. It does have various problems such as dishing effect, torn oxide defects and nitride residues in oxide. So, it leads to severe circuit failure, which affects yield. In this paper, we studied the characteristics of polishing pad, which can apply STI-CMP process for global planarization of multilevel interconnection structure. Also, we investigated the effects of different sets of polishing pad, such as soft and hard pad. As an experimental result, hard pad showed center-fast type, and soft pad showed edge-fast type. Totally, the defect level has shown little difference, however, the counts of scratch was defected less than 2 on JR111 pad. Through the above result, we can select optimum polishing pad, so we can expect the improvement of throughput and device yield.
