정영하,최기영,김석권 대한성형외과학회 1992 Archives of Plastic Surgery Vol.19 No.3

Many methods are used for genioplasty, such as alloplastic implants, horizontal osteotomy, bone or cartilarge graft and so on. Among these methods, alloplastic implants and horizontal osteotomy are most frequently used. Augmentation of chin with a silastic rubber implant is the procedure of choice for mild form of microgenia. But this technique has disadvantages of possible malposition or bone erosion and is contraindicated in the patients with a moderate to severe degree of microgenia, which are apparent in both sagittal(anteroposterior) and horizontal dimensions. The preferred technique is the horizontal osteotomy, which yields excellent results, even in the difficult cases such as implant failure, asymmetry, or vertical mandibular disproportion. It is a safe, reliable, and simple procedure that is relatively free of either significant side effects or complications. We performed 6 cases of horizontal osteotomy and concluded as follows., 1. The procedure is relatively simple 2. This method is widely applicable to various conditions of chin deformity, and especially more natural degree of microgenia. 3. It effectively influences soft tissue in submental region as well as bone contour with a more natural aesthetic results. 4. The osteotomy line should be placed at least 2mm inferiorly to mental formen. 5. It is safe and relatively free of complications with maximal aesthetic results.

In neonate, osteomyelitis of the calcaneus is extremely rare and various reports have indicated that it accounts for 3~8% of all bone infections among neonates, infection can result from hematogenous seeding or direct inoculation, as seen in puncture wounds (accidental or for blood sampling), open fracture, degloving injuries. and extension of pressure ulceration. Although direct inoculation has been reported to be the more frequent cause, other reports suggest a hematogenous etiology in the majority. We compared our experience that neonate calcaneal osteomyelitis after hind foot capillary blood sampling for cogenital metabolic deficiencies test and follow up of bilirubin level at Paik Hospital, Inje University, Pusan, Korea to that reported in the literature to determine if the experience at this institution was similar to that previously reported. Additionally, characteristics of the clinical presentation, laboratory investigation, treatment, and outcome were studied to determine if any factors might be helpful in making an earlier diagnosis, improving outcome, or both.

T lymphocytes are thought to play a central role in cell mediated immune response. To Study the T lymphocyte proliferative response to 30-kDa antigen purified from Mycobacterium tuberculosis H37Rv, peripheral blood lymphocytes isolated from healthy subjects were stimulated with the 30kDa antigen, crude antigen or PHA. Healthy subjects were divided into three groups so that PPD(+), PPD(±) and PPD(-). The proliferations of lymphocytes were measured by the incroporation of ^3H-thyrnidine. The results were summarized as follows: 1. For the PPD(+) person, at concentration of < 1 ㎍/ml, the proliferative response to 30-kDa antigen resulted in a mild reduction but crude antigen showed relatively rapid reduction. For the PPD(-) person, decreasing the concentration of the both antigens showed rapid reduction of proliferation 2. The lymphocytes proliferations to 30-kDa antigen and crude antigen were significantly increased in PPD(+) group when compared to those in PPD(-) group, but PHA response was no significant difference. 3. The sensitivity and specificity of lymphocyte proliferation assay to 30-kDa antigen and crude antigen when compared with skin test results were 92.3%, 100% and 76.9%, 50%, respectively.

The parties in the trade can have full autonomy and can resolve disputes independently, impartially and without delay by selecting arbitration by agreement. Korea and Japan had revised their Arbitration Laws to incorporate as many provisions of the 1985 UNCITRAL Model Law as possible. Japan had amended its century-cld arbitration law, becoming the 45th country to adopt the UNCITRAL Model Law on International commercial arbitration. New Arbitration Law was enacted as Law No.138 of 2003 and effective on March 1, 2004, is applicable to both national international arbitration. Korea had amended its arbitration law on December 31, 1999 and its New Arbitration Law incorporates the most of the 1985 UNCITRAL Model Law as Japan. Arbitration must be popular in resolving international commercial disputes in Northeast Asian bloc in order to increase the volume of intra-trade in the Northeast Asian bloc. But in order for the parties to make use of arbitration in the bloc, the arbitration laws of nations in the bloc must have similarity and unification. As Korea and Japan playes important roles in the bloc, both nations's arbitration laws must be studied in view of similarity and difference to unify both nations' arbitration laws by way of showing an example. Therefore, this paper deals with both nations' arbitration laws in view of comparative law to unify their arbitration laws and Northeast Asian Nations' arbitration laws.

현재 서양의학에서 활용되고 있는 항암 요법으로는 外科處置, 化學療法, 放射線療法 및 免疫療法 等이 있으며, 그 중에서는 抗癌劑에 의한 화학요법과 방사선요법이 가장 많이 응용되고 있다. 그런데 이들은 癌細胞뿐만 아니라 正常細胞까지도 殺傷함으로써 腫瘍細胞를 억제하는 동시에 骨髓造血器, 消化系統 및 免疫機能을 포함하는 인체의 정상적인 기능을 손상시키는 문제점으로 그 사용에 제한을 받고 있다. 따라서, 본 연구는 蔘茸扶正湯의 항암요법으로 손상된 조직의 회복 및 조혈촉진 효과를 규명하기 위해 생쥐를 대상으로 하여 실험하였다. 그 결과, 생쥐 비장세포에 대한 增殖效果, 造血促進因子의 分泌能, 방사선에 대한 임파구의 防禦效果, 방사선에 대한 조혈세포 防禦效果, 방사선(9Gy)을 조사받은 생쥐의 生存率 등에서 유의성있는 결과를 얻어내어 아래와 같이 보고하는 바이다. Radiotherapy is an irreplaceable method of cancer treatment. But it has several side effects, especially damages to the hemopoietic and Immune system. Therefore radioprotectors are required to treat cancer successfully. A lot of Herbs and Herbal prescriptions are reported to have radioprotective effects. Above all, those to support the healthy energy and strengthen the body resistance are found more effective. This study was performed to evaluate the radioprotective effects of prescription Shenrong Fuzheng Tang(S. F. T), which consists of 16 kinds of herbs. We investigated proliferation of murine splenocytes, secretion of colony-stimulating-factors(CSFs), immunocompetence after irradiation in-vitro, and Endogenous spleen colony assay, survival assay in-vivo. When splenocytes were cultured with Shenrong Fuzheng Tang (S.F.T) (500㎍/㎖), proliferation was enhanced 5.7 times compared to control cultured with medium alone(P〈0.05) and, showed highest proliferation at 4th day after incubation. In order to evaluate stimulation of hemopoiesis of Shenrong Fuzheng Tang(S.F.T), the supernatant of splenocytes cultured with optimal concentration of Shenrong Fuzheng Tang(S.F.T) was used to measure CSFs secretion. The result showed enhanced secretion of colony-stimulating-factors(CSFs) compared to control(P〈0.05). To evaluate the protective effect of lymphocytes from irradiation, proliferation of splenocytes stimulated by LPS and ConA after incubation with Shenrong Fuzheng Tang(S.F.T) for 24h Prior to Irradiation(1∼3 Gy) was measured. The results showed higher proliferation of Shenrong Fuzheng Tang(S.F.T.) treated cells than that of non-treated cells. And percentage increases of irradiated splenocytes per non-irradiated splenocytes were also higher in Shenrong Fuzheng Tang(S. F. T)-treated cells than control. Endogenous spleen colony assay, to evaluate the protection of hemopoietic cells form irradiation, showed increased number of colonies(p=0.03) in Shenrong Fuzheng Tang(S.F.T) treated murine spleen(10.3±1.9) compared to non-treated murine spleen(3.4±0.8). Survival time of mice irradiated with lethal dose of γ-ray(9Gy) was prolonged in Shenrong Fuzheng Tang(S.F.T) treated group prior to irradiation as compared to non-treated group. According to these results we can suggest that prescription Shenrong Fuzheng Tang(S.F.T) has radioprotective effects and be used to protect the hemopoietic and immune system from damages of anti-cancer radiotherapy.

이중보온 온수배관의 부식피로균열 특성에 관한 연구

The corrosion fatigue properties of thermally insulated pipeline were investigated in synthetic groundwater by electrochemical test, corrosion fatigue test and SEM analysis. Since the potential difference between the weldment and the base metal was small, the pipeline steel was not susceptible to galvanic corrosion. No fatigue limit was apparent for corrosion fatigue testing with remarkable reduction of fatigue lifetime. The effects of insulation and stress on the corrosion fatigue resistance of pipeline steel were studied through linear polarization resistance (LPR) and electrochemical impedance spectroscopy (EIS) during corrosion fatigue testing. The result of LPR measurement indicated that the corrosion rate was determined not by the water content of PUR foam but by the magnitude of applied stress. The better corrosion fatigue property of the insulated steel was attributable to the formation of a protective rust layer under the insulation, which reduced the acceleration of corrosion process and the propagation of fatigue crack. This was confirmed by the results of EIS measurements and SEM observation.

최태성,우극현,김진석,박완섭,함정오,정상재,유재영 대한산업의학회 2001 대한직업환경의학회지 Vol.13 No.2

목적 : DMAC에 노출된 후 집단적으로 발생한 독성 간염 7례보고. 방법 : 2000년 2월 신설된 스판덱스 섬유제조 공장에 근무하는 생산직 근로자 178명중 2000년 2월 부터 8월까지 7명이 간장질환이 발생하였다. 환례들의 나이는 23∼47세였고, 남자 5명, 여자 2명이었다. 이들에 대해 혈액검사, 간 초음파 검사 등의 임상검사와 작업장 조사를 실시하였다. 결과 : 근무 부서는 중합 1명, 방사 1명, 권취 4명, 그리고 포장 1명이며 평균근무기간은 10주였다. 주 호소 증상은 심한 피로감, 어지럼증 및 황달이었고, 검사실 소견상 독성간염의 소견을 보였다. A, B 및 C형 간염 표지자 검사는 모두 음성이었고, 간초음파 소견상 특이 소견이 없었다. 문진 상 알코올 성 간염을 일으킬 정도의 음주력이나 최근 약물 복용력을 가지고 있는 환례는 없었다. 입원 후 보존적인 치료로 모두 급속히 호전되었다. 초기에 발생했던 환례에서 퇴원후 DMAC에 재 노출되어 독성 간염이 재발되었다. 이후 모든 환례들은 퇴원 후 DMAC 비노출 부서로 전환하였고, 퇴원후 지속적인 추적검사에서 간 효소 수치가 완전히 정상화되었고, 정상화되는 기간은 1∼2개월 정도 소요되었다. 결론 : 환례들의 임상증상, 검사결파, 노출력 및 과거력상 DMAC에 의한 독성간염으로 추정된다. Dimethylacetamide is widely used in the production of plasics, resins, synthetic fibers, and gums and in purification and crystallization processes. Inhalation of the vapor or skin absorption of the liquid of dimethylacetamide (DMAC) can cause liver damage. Toxic hepatitis possibly attributable to DMAC exposure occurred in seven works among 178 employees who had worked on a new spandex-fiber production line. A large amount of DMAC is used as a spinning solvent for synthetic fibers in the factory. The patients were aged 23-47 years old and composed of five males and two females. They were involved in the process of polymerization(1 patient), spinning(1), take-up(4) and packaging(1). The mean duration of exposure was 10 weeks. They experienced fatigue, dizziness and jaundice. The patients showed elavated total bilirubln, alanlne aminotransferase (ALT), and aspartate aminotransferase (AST) levels. The serologic test for viral hepatitis A, B and C were negative, as were the abdominal ultrasonographic scans. Based on the presumptive diagnosis of DMAC-induced toxic hepatitis, they were removed from the workplaces. One or two months after removal from the work, the transaminase levels returned to normal. The patients had no history of significant alcohol use, blood transfusion, recent medication, and drug abuse. As a result, authors could not find any attributable cause of toxic hepatitis but the toxicity by DMAC exposure.

최윤석,신동호,김상현,김정구 대한금속재료학회 2005 대한금속·재료학회지 Vol.43 No.4

In order to develop a new corrosion sensor for detecting and monitoring the corrosion of buried pipeline, the electrochemical property of sensors and the correlation of its output to corrosion rate of steel pipe, were evaluated by electrochemical methods in synthetic groundwater, two soils of varying resistivity (5,000 ohm-cm, 10,000 ohm-cm), and synthetic tap water. In this paper, two types of electrochemical probes were used: galvanic cells containing of pipeline steel-copper and pipeline steel-stainless steel (Type 304). The results of EIS measurement indicated that the sensor current was inversely related to sensor resistance, which was governed by the corrosion behavior of cathode. In galvanic corrosion tests, the galvanic current of Cu-CS probe was higher than that of SS-CS probe. The comparison of the sensor output and corrosion rates revealed that a linear relationship was found between the probe current and the corrosion rates. A good linear quantitative relationship was found between the Cu-CS probe current and the corrosion rate of pipeline steel coupons in the soil resistivity of 5,000 ohm-cm, and synthetic tap water. In the case of the soil resistivity of 10,000 ohm-cm, although the SS-CS probe showed a better linear correlation than that of Cu-CS probe, the Cu-CS probe is more suitable than SS-CS probe, due to the high current output.
