1) Risk factors of aterosclerosis is Hypertension, hyperlipidermia, diabetes, obesity, physical inactivity and excessive smoking. Aterosclerosis begins at young age and worsens with age, particularty more so in men than women. For people with risk factors of atherosclerosis, it is important to prevent atherosclerosis-related disease with dietary, living pattern and exercise prescription. 2) Ditary fibers promote exercise of the digestive tract and shortens the time food remains inside the digestive tract. It can prevent obesity, hyperlipidermia, aterosclerosis and colon cancer by blocking the absorption of cholesterol. Various vegetables and sea foods are rich in unsaturated fats and can act prevent the absorption of cholesterol inside the digestive tract. 3) Occurrence of Coronary Heart Disease can largely be attributed to blood serum cholesterol. Particular attention should be paid to the increase of LDL cholesterol and decrease of HDL cholesterol as risk factors(If overall cholesterol/HDL cholesterol is below 3.5, it should be brought up to just below 4.5). HDL cholesterol is a lipo-protein that prevents atherosclerosis. 4) People with blood pressure of 160mmHg/90mmHg or higher shows 5 times higher rate of occurrence of atherosclerosis-related disease than people with normal blood pressure of 140mmHg/90mmHg, and smokers of a pack a day shoes 3-5times higher rate of occurrence than non-smokers. 5) Essential fatty acids and unsaturated fats, which are contained in vegetable oils, promotes metabolism while preventing absorption. In fruits, pectin, water-soluble fiber, is present and lowers the level of cholesterol. By consuming foods that are low in cholesterol and saturated fats, and rich in unsaturated fats, aliomentotherapy alone can reduce the plasma cholesterol by 10-15%. 6) For patients with LDL cholesterol level of 190mmHg/dl or higher, or LDL level of 160mmHg/dl or higher, and two or more rusk factors, drug therapy should be considered. The LDL cholesterol level should be kept below 130mmHg/dl and, desirably lower if possible. If the patient already has coronary heart disease, LDL cholesterol should even be lowered to and kept at below 100mmHg/dl. In treating high cholesterol, it is effective to use Resin and Lovastatin together or Lovastatin in combination. 7) Regular exercise is effective in preventing coronary arterial disease such as angina pectoris and infaction, inside it can lower the blood pressure and aids in weight control and release of stress. 8) For ideal exercise, it should be aerobic with Intensity of 60-80%HRmax(50-70%VO₂max), duration of 15-60min/day. The frequency of 3-6/week is desirable the better exercise prescription is endureance aerobic exercise. To get more effect exercise, exercise consistency very important.

Although noise-induced hearing loss (NIHL) is the most prevalent occupational disease in Korea, only 10% of the diagnosed cases are compensated. Old (1989-94) and current diagnostic criteria, criteria for workers' compensation of NIHL in Korea, compensation formulas of American Medical Association/American association of Ophthalmology and Otolaryngology (AMA/AAOO), the Committee on Hearing, Bio-Acoustics, Biomechanics (CHABA), American Academy of Otolaryngology (AAO) recommendation were compared. Each criterion was applied on the audiomety data of 4044 workers (8023 ears), who had received the second line screening test of Special Periodic Health Examination Program for noise-exposed workers during 1991-2. First, the resulting proportions of NIHL cases by employing each criterion were compared and strength of agreement was measured using kappa value. Temporary Threshold Shift (TTS) was corrected by noise free interval, and the reduction ratio of NIHL cases was calculated. Theoretical progression model of NIHL was reconstructed from previous studies on the natural course of NIHL to evaluate the change of diagnosis result of each criterion in the model. The kappa value between old and current criteria was 0.19, 0.55 for current criteria and workers' com. criteria, ranging from 0.08 to 0.78, highest coincidence was observed between current criteria and CHABA formula. The current criteria produce most similar results with CHABA formula. If TTS is corrected for NFI, there is about 14% reduction of NIHL cases. The results of applying on NIHL progression model divided the formulas roughly into 3 groups, of which compensation criteria was the most, old criteria and AAO the least conservative. In conclusion, the result of 4 ㎑ audiometry should be excluded in evaluation of hearing level and a new hearing conservation program should be set out. Current diagnostic criteria has an ambiguity in that managerial concept for prevention and purpose of compensation is mixed up. The current diagnostic criteria and compensation criteria could be incorporated into a new formula which is based on the state of the art test for estimating everyday hearing disability.

The principle of dietary modification in the diabetes is controling total calorie control, and take orderly meals, and should restrict ingestion of the saturated fat acid, and the simple sugar, and by taking green yellow vegitable, seaweed, and fruit as sufficiently and take care of the ingestion of vitamin "B"type which would expedite suger digestihg metabolism, and it is better way to avoit the ingestion the salty food and alcohlic beverages. To the insuline dependent diabetics, in take of 55% of carbohydrate 25% of fat, and 20% of protein is proper method and increase in gestion of vegitable oil that contained the unsaturated fatacid. The exercise enhance the appetonce, and solidification of insuline activity, and expedite suger metabolism, and make the suger metabolism harmoniously. Especially durable txecise will give more effective to the non-insuline dependant diabetics than the insuline dependant diabetics, and in the non-insuline dependant diabetics, when perform this meal the rapy and the exercise the rapy simultaneously, it can reduce the % of body fat and will make effective for improvement of the insuline reaction to the trivial tissue. General exercise guidance will vecommend to take precedence over the medical diagnosis and an case history test before exercise begins, and the beginning of exercise, it start with light exercise, and gradually enhause intensity. Actual exercise program, will elevate an lungs function by the oxygenic exercise, and it is desirable exercise items that can cousumable proper energy, and suitable for doing proper exercise by doing walk, stroll, jogging, go up & down the stairs, swimming, badminton, and mountain climbing etc. Exercise intensity is suitable with 30-65% of Vo₂ max, and actual exercise intensity decision is preferable for criterion of subjective symptoms, such as, a condition of sweating brow, sweating on the clothes, and the breathing is hard condition. The exercise intensity may be changeable according to the, pattern of diabetes, in case of pattern 1, The first step is 30% of Vo₂ max and about 10 minutes; the second step is 40% of Vo₂ max and about 20 minutes; the thire step is 40% of Vo₂ max about 30 minutes; the fourth step is 50% of Vo₂ max and about 30 minutes, and in case of pattern Ⅱ, it perform the 1st step is 40% Vo₂ max about 30 minutes, the Ⅱnd step is 50% Vo₂ max about 40 minutes, the Ⅲrd step is 65% Vo₂ max about 60 minutes, and the duration time per each step is about one week and bothⅠ and Ⅱ type together, it is desirable to perform 5∼7days. Above duration of exercise and its freguincy determination will determine by the relation with the exercise intencity. Take snack that contains carbohydrate during exercise, and will discontinue the exercise when insuline activity is reach on high peak, and it is proper way taking 15∼20g's carbohydrate contained food against possibility of the low blood suger occurance after exercise. At last, it is much effective the exercose therapy is combined with the diet therapy for best diabetes treatment.

I've researched the causes, symptoms, disease attacks, dietary cures, and exercise prescriptions for hypertension. The conclesions are the following; 1. There are two hypertension classifications-congenital hypertension(85∼90%) and acquired hypertension(10∼15%). If both parents have hypertension, there is a 60% chance of inheritance. If one parent has hypertension, there is a 30%. Postnatally, hypertension can be influenced by eating too much meat and sodium, stress, obesity, lack of exercise and smoking. 2. hypertension, a disease in adults, causes stroke, heart disease, kidney disease, 18 percent of adults have hypertension and 30 percent of deaths is caused by hypertension. 3. Smoker's hypertension is five times worse than nonsmoker's. Fat people can have a lower hypertension by losing their weight. 4. The frequency of arteriosclerosis gets increased 5 times if one has a higher hypertension than 160 mmHg/95mmHg compared to others who have normal hypertension under 140mmHg/90mmHg. And smokers who smoke about a pack of cigarettes a day are 3 to 5 times more likely to get arteriosclerosis. 5. Any food that has less saturated fat and more unsaturated fat is preferred. The cholesterol level can be cut down by 10∼15% through diet only. 6. Regular exercise minimizes blood pressure. Losing weight and resolving stress can prevent arteriosclerosis. 7. It is ideal to exercise 3 to 5 times a week for 30 min to 60 min at the strength of 30∼50% V o2 max. Exercise intensity should gradually be increased to 50∼70% V o2 max depending on the person. Walking, jogging, swimming, cycling and hiking are some preferred aerobic exercising activities.

정승희,이주석,한형균,전창영,이해영 한국어병학회 2002 한국어병학회지 Vol.15 No.1

본 연구는 식물성 생약재의 열수추출이 농도별로 첨가된 사료를 넙치(Paralichthys olivaceus)에 경구 투여한 다음 비특이적 면역반응 및 질병 저항성의 향상여부를 알아보고자 하였다. 실험에는 약쑥과 삼지구엽초를 7:3(w/w)의 비율로 열추출한 후, 0%, 0.1%, 0.5% 및 1%의 농도로 첨가하여 만든 2종류 혼합생약재(2-혼합구)와 약쑥, 삼지구엽초, 연교, 구절초, 박하, 지유, 삼백초, 상백피, 팔각의 9종류 생약재가 동일한 농도로 열수추출한 후 제작한 9종류 혼합생약재(9-혼합구)를 사용하였다. 이들 농도별 첨가사료를 넙치(평균 10.3±2.5g)에 12주 동안 경구 투여하면서 혈청내 라이소자임 활성, 혈청의 Escherichia coli에 ??살균능력 및 혈액학적 변화를 조사하였다. 그리고 최종 투여 12주 후에 넙치 에드와드병의 원인균 Edwardsiella tarda의 생균 공격실험을 실시하여 상대생존율(RPS)로써 저항성 향상효과를 살펴보았다. 2-혼합구 0.1%는 비특이적 면역활성을 크게 증가시켰으며, 상대생존율이 67%로 높게 나타나 가장 효과적인 질병 저항성 향상효과를 보였다. 따라서 2-혼합구 0.1%는 넙치 체내 비특이적인 면역기구를 자극함으로써 어체의 자연저향성을 증강시켜 세균성 질병의 감염에 대한 방어력을 상당히 향상시킬 수 있을 것으로 사료된다. 9-혼합구 0.1% 및 0.5%는 비록 비특이적 면역활성은 증가시키지 못하였으나, 상대생존율은 각각 53%를 나타내어 질병 저항성을 일부 향상시키는 효과가 있었다. Effects of medicinal herb extract on nonspecific immune responses, hematology and disease resistance against Edwardsiella tarda in olive flounder, Paralichthys olivaceus were evaluated. Wormwood, Artemisia asiatica NAKAI and barrenwort, Epimedium koreanum NAKAI were mixed at a ratio of 7 : 3 (w/w) for 2-herbs extract and wormwood, barrenwort, Korean forsythia, Forsythia koreana NAKAI, chrysanthemum, Chrysanthemum zawadskii var. latilobum KITAMURA, peppermint, Mentha arvensis L. var, piperascens MALINV., great burnet, Snaguisorba afficinalis L., Lizard tail. Saururus chinensis BAILL., mulberry, Morus alba L., and star anise, Illicium varum HOOK, f, at the same weight for 9-herbs extract. Two-herbs of 9-herbs extract were prepared by heating after adding 10㎖ of distilled water per g of the herb mixtures. Fish (10.3±2.5g) were fed the experimental diets supplemented with the 2-herbs or 9-herbs extract at the different concentrations of 0%, 0.1%, 0.5% and 1% per kg diet for 12 weeks. Lysozyme and bactericidal activities of serum, and hematological characteristics were examined during experimental period. After feeding test period, all experimental groups were challenged with E. tarda. Lysozyme activity from the fish fed the diet supplemented with 0.1% or 0.5% of 2-herbs extract was significantly higher than the control. But there was no difference both in bactericidal activity and hematology among each group. Sixty seven % of relative percent survival values (RPS) in the group fed the diet supplemented with 0.1% of 2-herbs was higher than the other group and the control. These results suggest that supplenmentation of 0.1% of 2-herbs extract to a commercial diet may enhance disease resistance in olive flounder. Although both 0.1% and 0.5% 9-herbs extract did not improve non-specific immune reponses, they could enhance disease resistance of 53% RPS, respectively.

A gallium based alloy(GA) that was developed as a substitute for dental amalgam was investigated for electrochemical corrosion behavior in 4 kinds of electrolytes(1% lactic acid, 0.05% HCI, Modified Fusayama's artificial saliva, and 0.9% NaCl). The related corroded microstructure were examined and microanalyses were conducted using ICPES. Polarization tests were conducted by scanning from -1,500㎷ to 1,000㎷(vs.SCE) at 75㎷/min. The obtained results were as follows: 1. GA showed wide passivation area next to SYB in artificial saliva, suggesting good stability. 2. The amounts of Sn, Cu released from GA were similiar to those of CAV, and decreased in the order of KAT, SYB. 3. All of specimens were observed pits at the area of pores in electrolytes containing chloride ions, and forming much corrosion products in 1% lactic acid and artificial saliva after corrosion test. 4. From the surface analyses of XRD, GA showed much corosion products containing gallium at the surface after corrosion test. In conclusion, the corrosion resistance of GA was lower than that of SYB and similiar to that of CAV and KAT.

최한철,고영무,정재헌,신종연,김일선,최성욱,정효수 대한치과기재학회 1999 대한치과재료학회지 Vol.26 No.4

Dental magnetic materials have been applied to removable prosthetic appliances, maxillofacial prostheses, obturator and dental implant but they still have some problems such as low corrosion resistance in oral environments. To increase the corrosion resistance of dental magnetic materials, surfaces of Sm-Co and Nd-Fe-B based magnetic materials were plated with TiN and then electrochemical corrosion test were performed in 4 kinds of electrolyte solutions(0.9% NaCl. 1% lactic acid, 0.05% HCl and modified Fusayama's artificial saliva). From this study, corrosion behavior, amount of elements released, mean average surface roughness values and the changing of mean surface microhardness values were measured comparing with control group of non-sputtered plating magnetic materials. The results were as follows: 1. TiN layer coated on magnet grows into preferred direction with lamellar structure and its thickness is 3.0㎛. 2. Sm-Co base magnetic materials coated with TiN have good corrosion resistance in 1% lactic acid and their pitting corrosion can not be seen. 3. Nd-Fe-B base magnetic materials coated with TiN showed good tendency of corrosion resistance in 0.05% HCl solution. 4. The amount of elements released from both Sm-Co and Nd-Fe-B base magnetic materials coated with TiN were more significantly decreased than that of uncoated magnetic materials. 5. The mean surface roughness values of both Sm-Co and Nd-Fe-B base magnetic materials coated with TiN were smooth than that of uncoated magnetic materials after corrosion test. 6. The decreasing rate of microhardness of both Sm-Co and Nd-Fe-B base magnetic materials coated with TiN were lower than that of uncoated magnetic materials after corrosion test. 7. Dental magnetic materials coated with TiN produced various corrosion products such as TiO, TiO₂, Ti₂O₃on the surface and resulted in better corrosion resistance than uncoated magnetic materials. In conclusion, it is considered that the corrosion problem of dental magnetic materials could be solved to some extent by EB-PVD with TiN on the surface of dental magnetic materials.

윤영상,최종화,김용대,한선경,유영갑 충북대학교 컴퓨터정보통신 연구소 2004 컴퓨터정보통신연구 Vol.12 No.1

본 논문에서 제시한 32비트 테스트 코어는 기존의 ARM과 같은 32비트 RISC 코어를 대신하여 JTAG 및 코어브레이커의 회로 테스트를 위하여 고안되었다. 테스트 코어는 디버깅유닛을 바꾸어가며 재이식(retargetable) 가능하게 사용될 수 있다는 장점을 갖는다. 회로 합성 결과 하드웨어는 ARM과 비교하여 33% 정도의 게이트를 가진다. 테스트 코어는 보다 높은 디버깅 성능을 위해 다중로드(multiple load; LDMA)와 다중저장(multiple store; STMA)명령을 추가하였으며 단일로드(single load; LDR) 또는 단일저장(single store; STR)명령들에 비해 64% 정도의 처리시간 단축을 나타내었다. A 32bit RISC type core is designed to replace full processors for testing JTAG and core breaker modules. It is retargetable and can be utilized to test a debugging unit. The design uses about 33% of gates with respect to a fully designed ARM7. It has instructions, multiple load or store(LDMA, STMA), for debugging purposes. Simulation result shows that they reduce the execution time about 64% with respect to processors having a single load or store(LDR, STR) instruction.
