방향계 폴리에테르이미드를 건/습 상분리방법으로 막을 만들고 imide group이 갖는 선택 투과 특성과 표면층의 구조를 변화시켜 이때 나타나는 물-알콜 혼합액의 투과 증발 특성에 대해 연구하였다. 막의 선택성은 구조 변화의 반응시간에 따라 일정 시간까지 선형적으로 증가하였으며 이때의 구조 변화는 미 반응 막보다 치밀한 구조로 변화됨에 따른 효과로 보이고 있다. 치밀 막의 경우엔 90% 에탄올 용액에서 160의 선택성을 보였고, 이소프로필알콜용액에서는 2000이 넘는 높은 선택성을 보여줌으로써 이미드재료가 높은 투과 선택성이 있음을 보여주고 있다. 막의 투과도에 대한 온도 의존성은 온도 증가에 따라 선형적으로 증가하였고 선택도 또한 증가함을 보여주었다.

The purpose of this case study is to analyze the B2C security information service model using the robo-advisor, to develop various service models and to urge new companies to enter. Overseas robo-advisor service market is growing rapidly with the launch of various B2C service models beyond B2B. On the other hand, as the domestic market is dominated by B2B services and serviced just index portfolio which is nascent, it lacks products which are used for active asset management. Recently as the government announced the approval of online investment advisory service, the B2C market of domestic asset management has entered a growth phase, centered on generations familiar with IT. We propose to extend the concept of Robo-Advisor service in accordance with the financial market change. By that model, we will study the case of the algorithm of the investment masters' philosophy and contribute to the expansion of the B2C service market.

목 적 : 고주파 온열치료 시 약물투여 및 혈액채취에 사용되는 케모포트로 인한 열적 변화를 알아보고자 한다. 대상 및 방법 : 전극 크기 20 cm인 고주파 온열치료기(EHY-2000, Oncotherm Kft, Hungary)를 이용하여 현재 본원에서 사용 중인 케모포트 중 재질이 플라스틱인 소재, 티타늄을 둘러싼 에폭시 소재와 티타늄 소재 케모포트를 자체 제작한 직경 20 cm, 높이 20 cm 원통형 한천(Agar)팬텀에 삽입하여 온도를 측정하였다. 온도측정기(TM-100, Oncotherm Kft, Hungary) 그리고 Sim4Life(Ver2.0, ZMT, Zurich, Switzerland) 프로그램을 사용하여 실제 측정된 온도변화와 비교 분석하였다. 측정위치는 전극 중심축 및 중심축 측면 1.5 cm지점에 각각 0 cm(표면), 0.5 cm, 1.8 cm, 2.8 cm 깊이별로 하였다. 측정조건은 온도 $24.5{\sim}25.5^{\circ}C$, 습도 30 ~ 32%, 출력 전력 100 W로 5분 간격으로 총 60분을 측정 하였다. 결 과 : 케모포트 미사용, 플라스틱, 에폭시 그리고 티타늄 케모포트를 사용한 경우의 최고온도는 전극 중심축 2.8 cm 깊이에서 측정값 $39.51^{\circ}C$, $39.11^{\circ}C$, $38.81^{\circ}C$, $40.64^{\circ}C$와 모의실험값 $42.20^{\circ}C$, $41.50^{\circ}C$, $40.70^{\circ}C$, $42.50^{\circ}C$이며, 전극 중심축 1.5 cm 측면 2.8 cm 깊이에서 측정값 $39.51^{\circ}C$, $39.32^{\circ}C$, $39.20^{\circ}C$, $39.46^{\circ}C$와 모의실험값 $42.00^{\circ}C$, $41.80^{\circ}C$, $41.20^{\circ}C$, $42.30^{\circ}C$이다. 고안 및 결론 : 고주파 전자기장에 의한 케모포트 주위의 열적 변화량은 부도체 물질인 플라스틱과 에폭시 소재에서 미사용의 경우보다 낮게 나타났으며, 도체 물질인 티타늄 케모포트에서는 약간의 차이를 보였다. 이는 케모포트내 금속 함유량 및 기하학적 구조에 의한 것과 이용 장비의 낮은 고주파 대역를 사용함에 있는 것으로 여겨진다. 즉 본 연구에 사용된 케모포트는 열 변화가 미미하여 장해를 고려하지 않아도 된다고 사료된다.

According to 2004 health statistics yearbook, cancer ocupies second death reason next to disease of blood circulation system and 1/4 was died because of cancer. There are very many factors to onset cancer, for example the exposure to varius kinds of pollution materials by development of industry, excess intake of harmful food to one's health, spritual stress, as become old age society, increase of attack-rate of geriatric diseases etc, attack-rate of cancer comes to be high gradually. The author had study about to treatment cancer by TCM(traditional chinese medicine) and combining TCM & western medicine, in Guang An Men hospital in Beijing of China from February 2003 to January 2004. TCM papers are 105 and combining TCM & western medicine papers are 280 of total 385 papers. Clinical reserch papers are 166, review articles are 194, animal experimental papers are 25. The papers used development herbal medicine are 42(10.9%), the papers used undevelopment herbal medicineare are 228(59.2%), the papers used senior TCM doctor's therapeutic experience and theory are 17(4.4%), the papers used theory of TCM or theory of combining TCM & western medicine are 71 (18.4%), the papers used acupuncture, qigong, thermotherapy, etc, other methods are 5, the papers used TCM patient's care or dietary treatment are 12 and ststistical papers are 10. Cancer is complicated hard case disease in pathological process. Combining TCM & western medicine treatment system is more efficient than one of TCM or western medicine in diagnosis, treatment, reserch of cancer.

국내 대부분을 차지하고 있는 자갈 도상궤도는 지속적인 열차반복하중에 의해 마모, 노반으로 관입, 노반표면의 불균질 등에 의해 도상자갈의 기능을 상실하게 된다. 이러한 현상이 지속적으로 발생하면 설계 당초 주요 기능이었던 배수기능을 충분히 발휘하지 못하기 때문에 강우가 노반에 체류되고 물로 인해 간극수압이 증가하여 전단강도가 저하되어 점진적으로 노반이 연약화된다. 이 논문에서는 원형모형실험을 이용하여 부직포 3종류에 대하여 0일, 3일, 7일 체수조건으로 하여 반복하중을 재하시킴으로써 부직포의 침하특성과 지지력 변화를 관찰하였다. 실험결과 0일 체수조건에서 토목섬유 보강과 무보강에 따라 최종 변위는 약 1% 차이가 있으며, 지반의 포화도가 증가함에 따라 침하량이 커지는 경향이 있었다. 보강재의 중량이 클수록 소성침하량이 작게 평가되었으며, 임계 함수비를 초과한 경우에는 부직포의 인장강도와 중량에 따라 침하량의 차이가 발생하였다. 또한 무보강과 비교해 볼 때 부직포에 의한 토압 저감효과는 있으나, 부직포의 중량에 의한 토압저감 효과는 영향이 미미한 것으로 평가되었다.

The purpose of this study was to evaluate microbiological hazards in the steps of production, transportation and selling of hamburger and sandwich that were marketed in CVS, then to identify methods of control. The reasults are as follows: As the reasult of operation surroundings of manufacturerand reserch of circulation, $4{\sim}6$ hours are needed from manufacturer to CVS. Also transportation car mean temperature was $10^{\circ}C$ which exceeds the standard of $7^{\circ}C$ or below. Hamburger: Critical control points identified were purchasing, cooking, post-preparation, transportation and holding at CVS. As the reasult of microbial analysis following the case of holding methods and reheating at CVS, microbes of cold holding and reheat after cold holding was within standard value. But in the case of room temperature microbes exceeded standard value. Sandwich: Critical control points identified were purchasing, cooking, post-preparation, transportation and holding at CVS. As the reasult of microbial analysis following the case of holding methods and reheating at CVS, total plate counts of cold holding and reheat after cold holding was within standard value. But in the case of room temperature holding after 24 hours total plate counts exceeded standard value. In the case of room temperature holding the number of microbes increased according to the passage of time. As a reasult of food poisoning bacteria, it was negative in every test in sample against V. parahaemolyticus, Salmonella, S. aureus.

Objectives: Recently lactic acid formulation was known as the adjuvant therapy on atopic dermatitis(AD) symptoms because of little side effects. In this study, it was studied that Lactobacillus mixed culture appliment was effective on not on AD symptoms. Methods: The case-photos 30-40 times of AD symptoms from case were observed with literatures. The case-photos were acquired with environmental AD dermatitis experience program which is conducted in SUNCHANG RESERCH INSTITUTE OF HEALTH AND LONGEVITY from 2014.01 to 2014.08. Experience applicants were limited the oral administration and chemical external administration. Results: Lactobacillus mixed culture appliment was effective because of the mitigation or disappearance of AD primary symptoms like pruritus, erythema, edema, effusion, dry skin, scaly, scab etc. AD symptom degree was dependent on lactobacillus mixed culture appliment times, and classified as Reaction Period (RAP), Reduction Period (RDP), Efection Period (EP), Reproduction Period (RPP) on a single mixed culture appliment time. And AD symptoms which were appeared in RPP were classified as Rebound Period (RBP), Effection Period (EP), Subclinical Period (SCP). Conclusions: Lactobacillus mixed culture appliment is considered to be useful for AD symptoms and is estimated to be effective by different mechanism with oral administration or steroid ointment application. Lactobacillus mixed culture appliment is expected to induce a synergistic effects on AD symptom reliefs with the other oral administration.
