The purpose of this study is to investigate the feasibility of applying the chitosan for a natural modant. The chitosan, a natural chelate macromolecule, is acquired from the crustacean. Investigation was focused on the change of the dyeability according to the chitosan treatment based on the Caesalping sappan and the color change of the dyed fabric according to the application of heavy metal mordant. The change of air permeability of the fabric with the dyeing was also investigated systematically. The effect of dyeing with/without mordant on the air permeability of the fabric after the chitosan treatment. It seems that increase in the dye-uptake is attributable to the fact that chitosan forms a complex with the Caesalpinia sappan and Al during mordant dyeing of cotton fabric. For nylon fabric, the darkest color was achieved on the occasion of non-mordant dyeing of the fabric. The mordant treatment or chitosan treatment, however, reduced the dyeability. While the dyed nylon fabric could maintain the same air permeability as the grey nylon fabric, the cotton fabric lowered the air permeability after dyeing.

전희종,서영조,오정언,김병진 崇實大學校 1999 論文集 Vol.29 No.1

The existing equipment with wire communication can expect the stability of data transmission. However, according to increasing a number of Measuring Instruments, wiring work becomes a heavy burden. Restriction to application about portable Measuring Instruments and the lack of flexibility are another drawback of wire communication. This paper presents the scheme of the design and implementation of a RF(Radio Frequency) based module. The RF based module is designed to the multi communication between Measuring Instruments. The RF based module consists of RF circuit and microprocessor. The main properties of RF circuit are maximum 5[Kbps] transmission rate, maximum 90m transmission distance and 433[MHz] frequency band. The microprocessor rearrange the data into AHDLC(Advanced High level Data Link Control) format and then instructs RF circuits to transmit/receive the data. The RF module is expacted to have a wide application field such as fire/security alarm, remote control/measurement etc..

전희대,이성열,이혜진,박영립,이종석,황규왕 순천향의학연구소 1998 Journal of Soonchunhyang Medical Science Vol.4 No.2

In 3 months randomized, double-blind, vehicle-controlled study of retinol (vitamin A 0.1%-3000IU/g) in the treatment of photoaging skin, especially eye wrinkles. 24 patients applied retinol contained cream to the both eye wrinkles and vehicle cream(placebo) to the same site. Half of the patients received retinol contained cream and half received vehicle cream(placebo). All 24 patients who completed the study showed statistically significant improvement in photoaging eye wrinkles on the retinol contained cream treated group, but not on the vehicle treated group. Eight of the 12 patients who received retinol contained cream to eye wrinkles had improvement in photoaging, whereas only three of the 12 patients who received vehicle cream(placebo) improved. In retinol contained cream group, there is a some relationship between water contents and effects. In other words, as water contents were the higher, effects were the better. The side effects were limited to mild irritation of retinol contained cream treated skin. Retinol contained cream appeared to be safe and effective in the treatment of eye wrinkles.

Non-Hodgkin's 림프종의 약 40%는 결절외(extranodal) 림프종으로 대개 위장관에서 발생하며 이들 중 점막 연관 림프조직(mucosa-associated lymphoid tissue: MALT)에서 기원한 림프종은 MALT 림프종으로 분류된다. 위 외의 부위에서 원발성으로 발생하는 MALT 림프종은 매우 드물지만 실제 거의 모든 신체 장기에 발생하는 것으로 알려져 있는데, 가장 흔한 부위인 위 외에도 폐, 갑상선, 침샘, 눈물샘에 발생하고, 드물게 안구, 유방, 방광, 신장, 흉선 등에도 보고된 바 있다. MALT 림프종은 오랜 기간동안 원격 전이하지 않고 국소 병변으로 남아 있는 특징이 있어 치료 방향 또한 국소 병변의 치료에 집중되며, 예후도 림프절 기원의 림프종에 비해 양호한 것으로 알려져 있다. 본 저자 등은 자궁 내막에 원발성으로 발생한 MALT 림프종 1예를 경험하였기에 문헌 고찰과 함께 이를 보고하고자 한다. Mucosa associated lymphoid tissue (MALT) lymphoma can rarely develop primarily in extranodal sites other than stomach which is the most common site for it. Other rare primary sites are small intestine, colorectum, esophagus, lung, thyroid, salivary gland, lacrymal gland, breast and skin. MALT lymphoma represents a distinct clinicopathologic features: it is usually localized to their original site for a long time and shows much more favorable prognosis than lymphoma at other site, but some MALT lymphoma can arise simultaneously or successively in different organ or give rise to another MALT lymphoma of other organ and can be multifocally disseminated or recurred. We report a very rare case of high grade B-cell lymphoma of mucosa associated lymphoid tissue (MALT) of the uterine endometrium, which was confirmed by immunohistochemical assay.

저자들은 폐결핵 추정하에 치료를 받았던 Sarcoidosis 환자 1례를 경험했기에 문헌적 고찰과 함께 보고하는 바이다. Sarcoidosis is a granulomatous disease of unknown etiology In which pulmonary manifestations typically predominate with protean extrapulmonary and systemic manifestations. In sarcoidosis, pulmonary symptoms include dyspnea on exertion, non-productive cough and wheezing. Typical radiologic finding is a diffuse infiltration with or without bilateral symmetric hilar lymphadenopathy. Sarcoidosis should be differentiated with pulmonary tuberculosis because of its clincal and radiological slmilarity in Korea, an endemic area of pulmonary tuberculosis. We report a case of sarcoidosis patient whose symptoms were not improved by treatment with anti-tuberculous medication, but by steroid therapy following the diagnosis of sarcoidosis made by biopsy.

제올라이트 흡착제 상에서 이산화탄소 회수를 위한 PSA 공정 연구 : 공정성능에 대한 세정유량의 영향 Effect of Rinse Rate on Process Performance

전종기,박영권,주국택 한국대기환경학회 2004 한국대기환경학회지 Vol.20 No.1

In order to investigate the performance of carbon dioxide PSA over zeolite adsorbent, the present study showed results of isotherm measurement, cyclic operation of 3-bed apparatus, and the corresponding numerical simulation. The experiment data of bed temperature, purity, recovery were matched well with that of numerical simulation. Purity of both gas and adsorbent phase increased rapidly with rinse rate but the degree of increase was retarded for large rinse rate. The total amount of adsorbed increased only 10% even if rinse rate was enlarged to 4 times. Optimal rinse rate was 7 Nm³/hr in this study. The heating rinse led to augments in recovery and productivity, possibly thanks to ease of desorption resulting from increased volumetric rinse rate and temperature rise in the column.

Interface Shear Strength at Joints of Ultra‑High Performance Concrete Structures

Young?Jin Kim,Won?Jong Chin,Se?Jin Jeon 한국콘크리트학회 2018 International Journal of Concrete Structures and M Vol.12 No.6

When ultra-high performance concrete (UHPC) is fabricated as precast members such as in a UHPC segmental bridge, the joint design between the precast members can significantly affect the overall integrity and safety of the structure. Therefore, the structural behavior of the UHPC joint was experimentally investigated in this study with test variables including joint type, number and height of shear keys, type of filler, curing temperature, and lateral compressive stress. The UHPC considered in this study is the K-UHPC developed in Korea with a specified compressive strength as high as 180 MPa and high flowability. The joint shear strengths affected by the test variables were investigated in detail. The test results were also compared with two representative predictive equations for interface shear strength to determine an appropriate equation for the joint design of UHPC. These equations did not match well with the test data because they were originally proposed for normal strength concrete. However, the JSCE equation could be improved by modifying a coefficient to show good agreement with the test especially in the case of the dry joint with epoxy application.

Preparation of petroleum impregnating pitches from pyrolysis fuel oil using two‑step heat treatments

Jong‑Eun Choi,Seunghyun Ko,Young‑Pyo Jeon 한국탄소학회 2019 Carbon Letters Vol.29 No.4

Petroleum-based impregnating pitches were prepared from pyrolysis fuel oil (PFO) using a two-step heat treatment without a separation process. The pressurized heat treatment, the first step, was used to improve the properties of the pitches and enhance the product yield by promoting the cracking and polymerization of the components in the PFO. An atmospheric heat treatment as the second step was used only to synthesize the impregnating pitches from the liquid pitches prepared during the first step. The prepared impregnating pitches had the properties of a commercial petroleum-based impregnating pitch. The impregnation performance was evaluated by HT-XRD and an impregnation test. The HT-XRD results showed changes in the stacked structure of the pitches at the impregnation temperature. The bulk density of the carbon block was increased to 14.3% and the porosity was reduced by 10.3% after the impregnation/recarbonization process. The high reaction temperature during the first step induced the formation of quinoline insoluble (QI) components during the second step of the treatment, and the QI components adversely affected the impregnation process.
