        A study on efficient gate system based RFID at the container terminal

        Hyun,Kim,Yul-Seong Kim 한국항해항만학회 2006 한국항해항만학회지 Vol.30 No.4

        It is a world trend to construct large terminal and develop automated container terminal to attract Super Post-Panamax and provide service which is based on differentiation In fact, there is insufficient research for automatization of terminal gate since the automatization of current constructed container terminal is only focused on increasing productivity and unmanned system through the automatization of quay, yard, etc. In this paper, we have investigated advantage/disadvantage of existing gate operation systems and compared each gate operation system in the aspect of raising terminal image and the productivity. For the specific study, we have used data from actual terminal gate operation and RFID model business sponsored by MOMAF (Ministry of Maritime Affairs and Fisheries). As a result, this paper carried out an efficient gate operation system and it has been expected that it will be performed as groundwork of automated gate operation system which is for design of container terminal and improvement of gate operation system.

      • 악성흑색종과 양성멜라닌세포성모반에서 bcl-2 단백발현에 관한 면역조직화학적 연구

        이성열,이종석,김현조,정현,조현듯,김의한 순천향의학연구소 2001 Journal of Soonchunhyang Medical Science Vol.7 No.2

        Background: The bcl-2 protein, contrast to p53, has been shown to be suppress the apoptosis, and overexpression of the bcl-2 protein has been reported in several malignant tumors. Although how the bcl-2 protein takes part in tumorigenesis has not been proved, the bcl-2 positive tumors appeared to have good prognosis in some malignant tumors. The expression pattern of the bcl-2 in melanocytic nevi and malignant melanoma have not been well known. The authors analyzed immunohistochemically expression of the bcl-2 protein to investigate the role of the bcl-2 protein in developing malignant melanoma. Method: 10 malignant melanoma and 10 benign melanocytic nevi were immunostained with anti-bcl-2 monoclonal antibody. Results: In malignant melanoma, 1 case was 2+ positive, 9 cases were 3+ positive. In benign melanocytic nevi, 2 cases were 2+ positive, 8 cases were 3+ positive. Conclusion: Bcl-2 protein is expressed by benign melanocytic nevi and malignant melanoma. There is no difference of bcl-2 protein expression in melanocytic nevi and malignant melanoma.

      • 고유함수전개법을 이용한 비대칭 유전체 원주공진기의 공진특성해석

        류원열,민경호,장중호,전오곤,이창화,최현철 경북대학교 센서기술연구소 1998 센서技術學術大會論文集 Vol.9 No.1

        The resonant frequency of the dielectric rod resonator which is surrounded by cylindrical cavity can be calculated very exactly by using eigenfunction expansion method in the concept of electric and magnetic wall from the symmetry. But if the supporter is put in the cavity, the symmetry disappears. Thus this method has some errors. In this paper, the resonant frequency of the asymmetric dielectric rod resonator was calculated by using the eigenfunction expansion method. Also, the effect of the supporter was discussed. Then we found that the resonant frequency was more affected in the case of TM mode than TE or Hybrid modes as the length of the supporter was longer.

      • o,m-Benzene-di-Sulfonyl Chlorides의 친핵성 치환반응에 대한 연구

        옥치율,박현석 부산교육대학교 과학교육연구소 1989 科學敎育硏究 Vol.14 No.-

        The Nucleophilic substitution reaction of o, m-benzene-di-sulfonyl chlorides with various substituted anilines in methanol-acetonitrile binary solvent mixtures at -15℃ For the reactivity of substrates, m-benzene-di-sulfonyl chloride has higher than o-benzene-di-sulfonyl chloride according to the steric effect of ortho position and the order of magnitude for the second order rate constants, p-CH_3 aniline > aniline > p-Cl aniline is the tendency of nucleophilicity as expected. The magnitudes of ρ_N and β are lager than benzensulfonyl chloride and indicate a relatively advanced bond-formation in the transition state. Relatively small values of a/s is an indication that the polarity-polaribility(π^*) of solvent contributes more than the hydrogen bond donor acidity (α). The reaction proceeds via an associative S_N2 mechanism.

        吳澤烈,張現貴 慶熙大學校 材料科學技術硏究所 1992 材料科學技術硏究論集 Vol.5 No.-

        Mechanical properties of dual phase steel are affected by the microstructural factor, such as, martensite volume fraction, grain size of ferrite, hardeness ratio of ferrite-martensite, connectivity and chemical properties. In this study, the tensile test was carried out to analyze the tensile characteristic of the Ferrite-Martensite dual phase steel with the Hardeness Ratio of four kinds. The result obtained could be summarized as follow ; The calculated Stress-Strain curves for four hardeness ratios were compared with their corresponding experimental curves, and in general, good agreements were found. After tensile tests were done at various tempering temperatures, we had a result that the tensile strength at 200℃ was the largest. It was found that for a given hardeness ratio, the calculated stress-strain curve was higher than experimental curve. The more reduce the hardeness ratio, the more narrow the gaps between the experimental curve and the calculated curve. It is related with the plastic constraint factor K.

        오동열,서현주 大韓神經精神醫學會 1996 신경정신의학 Vol.35 No.4

        본 연구는 첫째, 국립서울정신병원 입원환자의 다음증유병율과 그 측정방법에 관하여 알아보고 둘째, 다음증환자의 특성을 알아보기 위해 다음증군과 대조군의 임상특성 및 생물학적 지표를 비교하였다. 국립서울서울정신병원에 입원중인 환자 634명을 대상으로 다음의 진단 기준 (1)(2)(3)중 하나라도 만족시키는 환자를 다음증 환자로 결정하였다. (1) 치료진의 보고상 입원 중 다음증으로 인한 물중독의 삽화가 명백히 있는 경우 (2) 3회 연속 뇨비증이 1.008이하이면서 하루 3리터 이상의 물을 섭취하는 경우 (3) 3회 연속 뇨비증이 1.008이하이면서 혈중 나트륨 농도가 135mEq/L이하인 경우 위 진단기준을 만족시키는 환자는 총 24명으로 전체 환자의 3.79%였다. 다음증군 20명과 대조군 20명의 임상특성 및 생물학적 지표의 비교를 통하여 다음증 환자의 특성을알아보았다. 연구 결과는 다음과 같다. 1) 유병기간, 항정신병약물 용량, 경련, 전기경련치료, 흡연, 기타 약물 사용은 두 군간에 차이가 없었다. 2) 다음증군에서 대조군보다 뇨비증이 더 낮았고 물 섭취량이 더 많았다. 일중 체중변화(normalized diu-mal weight gain)는 두 군간에 차이가 없었다. 3) 다음증군에서는 혈중 항이뇨 호르몬(antidiuretic hormone 이하 ADH)이 정상범주에 들었으나 대조군에서는 정상범주보다 높았다. 또한 다음중군에서는 혈중능동삼투농동(osmolality 이하 Osm)가 정상범주보다 낮았으나 대조군은 정상범주에 들었다. 본연구의 결과를 전체적으로 종합한다면, 저자들의 진단기준에 따른 국립서울정신병원 입원환자의 다음증 유병율은 3.79%이며 다음증 측정방법으로 치료진의 보고, 뇨비증, 혈증 나트륨 농도, 물 섭취량의 측정 등을 제시할 수 있겠다. 그리고 다음증군과 대조군의 비교에서 유병기간, 항정신병약물 용량, 경련, 전기경련 치료, 흡연, 기타 약물 사용 등의 임상특성의 차이는 없었으나 뇨비증, 물 섭취량, 혈중 ADH와 Osm 같은 생물학적지표는 분명한 차이를 보임으로서 다음증군의 특성을 나타낸다고 할 수 있겠다. We attempted to estimate the prevalence of polydipsia in psychiatric inpatients in Seoul National Mental Hospital and to find out the identification method for polydipsic patients. We also compared the clinical and biological characteristics of polydipsic patients with those in nonpolydispic patients. Methods &Results : The following inclusion criteria were applied to the study subjects for estimating the prevalence of polydipsia among psychiatric inpatients at Seoul National Mental Hospital. 1) By staff report, that a objective clinical evidence of water intoxication during hos-pitalization was noted. 2) Three consecutive urine specific gravities were all less than 1.008 and also water intake was more than 3 liters per day. 3) Three consecutive urine specific gravities were all less than 1.008 and also serum sodium level was less than 135 mEq/L. By these inclusion criteria, we found 24 polydipsic patients among 634 hospitalized psychiatric inpatients, with the prevalence of 3.79%. Comparison of the clinical characteristics and biological determinants between 20 polydipsic and 20 nonpolydipsic patients produced the following results : 1) No differences were found in duration of illness, dosage of neuroleptics, seizure history, electroconvulsive therapy history, smoking, use of medications other than neuroleptics, between the groups. 2) There was no difference in normalized diurnal weight gain. But polydipsic patients showed more water intake and lower urine specific gravities than nonpolydipsic ones. 3) Plasma antidiuretic hormone levels were within normal range and osmolalities were lower than normal range in polydipsic patients. BUT plasma antidiuretic hormone levels were higher than normal range and osmolalities were within normal range in nonpolydipsic patients. Conclusion : The prevalence of the polydipsia was 3.79%. We suggest that staff report, urine specific gravity, serum sodium level, and oral water intake can be identification markers for polydipsta. Clincal characteristics such as duration of illness, dosage of neuroleptics, seizure history, electroconvulsive therapy history, smoking, and use of medications other than neuroleptics did not differ between polydipsic and nonpolydipsic patients. But biological determinants such as urine specific gravity, oral water intake, plasma antidiuretic hormone level, and osmolality differed beween the groups. Therefore these biological determinants could be adopted as biological markers for polydipsia.
