With a view to examining the habit and method in which old people maintain and improve their health, we consulted 551 men and 444 women who were over 65 years old, and concluded as follows: 1. Habit of eating It's been revealed that most of the old people keep a regular eating hour, control the quantity of meal or eat a little food, and prefer vegetables to meat. 2. Mental health Old people feel the necessity for mental health and most of them (about 80%) keep good mental health without becoming pessimistic. Their chief concenrs have turned out to be about their sons and daughters and their own health and finance. 3. Managing Good Health It has been revelaed that old people do not possess any special kind of secret to keep good health but taking plenty of rest, regular meal, and proper exercise, and many of them (about 60%) have been shown to eat invigorant food that they can easily get around their living area. 4. Physical Functions It has been revealed that many old people are conscious of some symptoms about their parts of body and about to percent of them suffers from neuralgia. Some measures like medical aid especially for old people need to be taken as soon as possible. As we have found that the health-keeping method of old people consists plenty of rest, proper exercise, and appropriate nutrition, we can conclude that the recreatonal and culture facilities and programs for keeping old people in good health should be developed. It is also necessary to study food that contribute to their health and develop ways to get rid of the stresses to which they are exposed in their daily life. Presides, it is natural that government found an administrative department to deal with these matters effectively.

X-선 발생장치 시설의 방사선 차폐 해석

문석형,최호신,권석근,육종철 대한방사선 방어학회 1987 방사선방어학회지 Vol.12 No.1

X-선 발생장치 시설에 대한 방사선 차폐해석은 두가지 측면에서 고려된다. 먼저 1차 방사선과 누설방사선에 의한 영향을 고려하여야 하며 본 연구에서는 NCRP-49 및 51에 제시된 방법을 사용하였다. 둘째, 시설의 미로 출입구에서는 산란방사선에 의한 영향이 보다 중요한데, 본연구에서는 이 영향을 평가하기 위하여 Albedo개념을 근거로 한 단순한 방법이 제시되었고, 이를 토대로 계산된 결과를 컴퓨터 코-드(MORSE-CG)의 계산치 및 실측된 결과와 비교하였다. 본 연구에서 제시된 방법에 의한 결과는 미로출입구 안쪽의 경우에 대한 해석에서는 약간의 오차를 보이고 있으나 미로출입구 문바깥에서는 비교적 잘 일치한다. 여기서 출입문바깥의 경우에 대한 해석이 방사선방어 측면에서 보다 중요하다는 관점에서 볼 때 이 방법은 의료용 또는 산업용의 X-선 및 감마선시설의 차폐설계 및 해석이 응용될 수 있을 것이라고 판단된다. Radiation shielding analysis for a 6MeV X-ray facility was carried out. The primary and leakage radiation for the facility can be evaluated based on the methodology in NCRP No. 49 and 51. The present study deals with radiation scattering analysis for the outside and inside door of the facility based on the albedo concept. The calculated dose rates were compared with the results of MORSE-CG code calculation and the measured data, resulting in a good agreement, even though there existed some deviation for the inside door. These results can be utilized to the radiation shielding design of the medical and industrial X and gamma ray facilities, and to the safety evaluation of these facilities.

중증 허혈성 지체질환 환자에서 시행된 vascular endothelial growth factor의 혈관신생 유전자치료 1예

김현중,장신이,김종묵,김선영,김병문,김원배,김덕경 대한내과학회 2003 대한내과학회지 Vol.64 No.1

저자 등은 기존의 치료에 반응하지 않은 중증 허혈성 지체질환 환자를 대상으로 하여 vascular endothelial growth factor를 이용한 혈관신생 유전자 치료를 시행하였다. 치료 후 환자의 허혈에 의한 하지 통증이 현격하게 감소하고 상처의 진행이 측부혈관이 많이 증가됨이 관찰되어 이에 문헌고찰과 함께 보고하는 바이다. We report VEGF-induced angiogenic gene therapy in a patient with critical limb ischemia, who did not respond to conventional treatment. This patient was the first case in a dose-escalating series of phase I clinical trial. The patient had severe resting pain, gangrene and diffuse ulcer in his left foot. Total 1,000㎍ of naked DNA encoding human VEGF165 was administered intramuscularly to 8 sites of the loft lower extremity. Four weeks after the first 1,000㎛ was administered to the same sites (total dose: 2,000㎛). After gene therapy, resting pain gradually reduced and the amount of analgesics taken by the patient decreased. The ischemic wound of lower extremity slightly improved. However, there was no complete wound healing at 12 weeks of treatment. Digital subtraction angiography at 12 weeks after gene therapy showed an increase in collateral vessels at the mid-tibial, ankle and foot arch levels. Immediately and up to 12 weeks, there was no complication related to gene therapy. These findings may be cautiously interpreted to indicate that intramuscular injection of naked plasmid DNA of VEGF_165 may induce therapeutic angiogencsis in a patient with critical limb ischemia. Further clinical evaluation of VEGF-induced gene therapy is needed to evaluate the safety and efficiency of this treatment.(Korean J Med 64:85-90, 2003)

In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria gonorrhoeae(PPNG), we have been trying to study the patients who have visited the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by menas of the chromogenic cephalosporin method. In 1998, 93 strians of N. genorrhoeae were isolated, among which 60(64.5%) were PPNG. The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 64.5% in 1998.

Shear viscosity measurement of highly filled polycarbonate melts using a slit-die rheometer

Moon, Jong-Sin,Lee, Jeong-Moo 한국유변학회 2013 Korea-Australia rheology journal Vol.25 No.3

Viscosity measurement and the flow behavior prediction of reinforced polymer melts have been considered crucial for quality consistency in commercial products where highly filled polymer composites are used. In this study, a slit-die rheometer mounted on an injection molding machine was employed to measure the shear viscosity of a reinforced polymer melt by monitoring the pressure drop in the slit and the ram movement for various melt temperatures and shear rates. Mold filling experiment was also conducted using an injection molding process with two plaque-shaped parts of different thicknesses. Polycarbonate with 40 weight % of glass fibers was investigated in the experiment. A comparative numerical simulation was conducted as well using the measured viscosity in the current study. The pressure drops from the simulation and the experiments were compared, which reveals that the viscosity measured using a slit-die rheometer is relatively accurate.

목적: 한국은 2000년에 소아마비 무발생국가로 공인되었으며, WHO의 권고에 의해 2005년부터는 경구용소아마비 생백신 대신 주사용 사백신을 사용하기 시작했다. 본 연구는 2006년부터 국내에서 사용되기 시작한 주사용 소아마비 백신(Poliorix$^{TM}$)의 안전성 및 이상반응을 우리나라 영아들을 대상으로 알아보고자 한다. 방법: 2006년부터 2012년까지 6년 동안 다기관공동연구로 조사하였으며, 2, 4, 6개월의 기초접종과 4-6세의 추가 접종 후 7일 이내 및 31일 이내의 이상반응 및 안전성에 대해 조사하였다. 결과: 총 639명 중 등록대상자 중 617명은 기초접종, 22명은 추가접종을 실시하였으며, 639명 중 73명(11.4%)에서 명시되지 않은 이상반응을 보고하였으며, 이중 가장 많은 증상은 상기도 감염증상으로 접종 후 7일 이내에 639명 중 16명(2.5%)에서 보고되었다. 1명에서 grade 3 이상의 장염증상을 보고하였으며, 11명(1.7%)에서 중대한 이상반응을 보고하였으나, 이들은 모두 연구 종료 이전에 호전되었다. 결론: 6년 동안의 시판 후 조사에서, 건강한 우리나라 영아들을 대상으로 한 주사용 소아마비 사백신(Poliorix$^{TM}$) 접종은 국내 건강한 소아에서 안전하고 내약성이 충분하였다. Objective: As per the requirement of Korean Food and Drug Administration, this post-marketing surveillance was conducted in Korea to evaluate the safety and reactogenicity of Poliorix$^{TM}$ following its introduction in 2006. Methods: In this open, multicenter study, the vaccine was administered as per the current practice of Korean doctors and in reference to the guidebook by the Korean Pediatric Society and as indicated in the Korean label which was as follows - for primary vaccination three doses were given to infants at ages 2, 4 and 6 months whereas, for the booster dose a single dose was given to children aged 4-6 years. Safety data during this six year surveillance was collected using diary cards which were distributed to the parents to record adverse events. Results: A total of 639 subjects were enrolled into the study. Of these, 617 subjects and 22 subjects received the vaccine as a primary and booster dose, respectively. At least one unsolicited symptom was reported in 11.4% (73/639) of the subjects during the 7-day follow-up period; upper respiratory tract infection (2.5%;16/639) was the most frequently reported unsolicited symptom. One subject reported at least one unsolicited symptom (gastroenteritis) of grade 3 intensity within the 31-day post-vaccination period. Approximately 1.7% (11/639) of subjects reported 13 serious adverse events (SAEs). All SAEs were resolved by the end of the study. Conclusion: In Korea, primary and booster vaccination with Poliorix$^{TM}$ was well-tolerated in healthy subjects when administered according to the prescribing information as part of routine clinical practice.

FEM Carrier용 PP-LFT 소재의 응력비 변화에 따른 피로 거동

문종신(Moon, Jong-Sin) 한국산학기술학회 2015 한국산학기술학회논문지 Vol.16 No.1

지금까지 자동차 소재의 경량화 및 연소가스의 저감은 부품의 플라스틱화를 통하여 많은 진전이 있었다. 장섬유 보강 폴리프로필렌 소재가 적용된 프론트 엔드 모듈 캐리어는 플라스틱 구조부품 중에서 가장 성공적인 사례이다. 하지만, 장기 신뢰성 측면에서 볼 때, 자동차용 플라스틱 소재에 대한 피로거동 및 진동내구에 대한 더 많은 연구가 필요한 실정이다. 본 연구에서는 프론트 엔드 모듈 캐리어의 피로설계 및 해석의 기초가 되는 폴리프로필렌 장섬유 소재에 대한 내구성을 분석하였다. 피로수명과 응력진폭 또는 평균응력 간의 상관관계를 평가하기 위하여 다양한 응력비에서 피로실험을 수행하였다. 일정 응력진폭에서 응력비를 변화시킨 결과는 최대하중을 고정시킨 결과보다 피로수명의 변화가 응력비 증가에 따라 2∼6% 크게 나타났다. 또한 주사전자 현미경을 통하여 장섬유 보강 폴리프로필렌 소재에 대한 피로균열의 발생, 전파의 파괴기구를 확인하였다. Plastics have brought a significant progress in reducing the weight of automotive parts and improving gas emissions by replacing steel parts. The front end module (FEM) carrier, which was made from long glass fiber reinforced polypropylene (PP-LFT), is one of the most successful examples. On the other hand, more research on the fatigue behavior and vibration durability of automotive plastic parts will be needed to improve the long-term reliability. This paper analyzed the durability of the PP-LFT, which is fundamental to fatigue design and analysis of FEM carrier. Various fatigue tests were conducted at different stress ratios to evaluate the relationship between the fatigue life and stress amplitude or mean stress level. In the case of a fixed stress amplitude, the change in fatigue life with the stress ratio was 2∼6% larger than the case of fixed maximum stress. Furthermore, this study observed the mechanism of initiation and propagation of the fatigue cracks in PP-LFT by scanning electron microscopy.
