In Fe–3%Si steel, the hot rolling process affects not only the hot rolling texture but also the primary recrystallization texture. Here, the effect of asymmetric hot rolling was studied by comparing the difference in the texture evolved between asymmetricand symmetric hot rolling. The effect of asymmetric hot rolling on the texture of primary recrystallized Fe–3%Si steel wasalso studied. The symmetric hot rolling of Fe–3%Si steel produces a rotated cube texture at the center but Goss and coppertextures near the surface. Asymmetric hot rolling tends to produce Goss and copper textures even at the center like thetexture near the surface. After primary recrystallization, the dominant texture at the center changes from {001} <210> to{111} <112> and the new texture has a higher fraction of the grains which make the low energy boundary with Goss grainsthan that of symmetric hot rolling.

Recently, as the alternatives to preserve environment such as effective usage of wastes or unusable resources are drawing attentions, researches and measures for the two tasks, which are reuse of waste wood and development of eco~friendly materials, are being examined and established in various fields. However, they are still insufficient. Therefore, in this study, for the efficient application of waste woods and eco~friendly effects, mortar was produced using sawdust as the waste wood and mineral material cement for combination, in order to produce inorganic boards using waste woods, which were made when sawing. The present study purposed to analyze the physical and dynamic characteristics of woody cement boards, which were made by modifying water~cement ratio for each wood inclusion rate based on a hardening~accelerator inclusion rate set in previous studies and, based on the findings, to provide basic data about the physical properties of inorganic boards made of waste wood, in order to produce woody cement boards using waste wood, which has problems in being used in the manufacturing of woody cement boards.
하악골 골절 치료를 위한 miniplate와 관련된 매복견치의 치험례

하악 좌측 견치의 미맹출을 주소로 내원한 10세 여환의 과거 병력 조사 중 3년 전 교통사고로 하악 좌측 골체부에 골절이 생겨 miniplate로 관혈적 정복술을 시행받은 것을 발견하였다. 통상적인 외과적 노출과 교정적 견인치료로는 견치 맹출에 실패하였고, miniplate를 제거함으로써 정상적인 매복 견치 맹출에 성공하였기에 보고하는 바이다. This case report describes the treatment of an impacted tooth in relation to pediatrlc mandibular fracture. A 10-year-old girl presented with an impacted mandibular canine related with a miniplate in the left mandibular body area. An ordinary surgical traction ended in failure. Good occlusion was established by removal of the miniplate. It would be considered important to make an exact diagnosis of the cause and remove the mechanical obstruction instantly for successful orthodontlc treatment of an impacted tooth.

Objectives: Under the fee-for-service system, Korean hospitals have been suffering from the worsening profitability caused by law medical care fees. To overcome the difficulties, they have maximized the quantity of medical services and made relatively large investment in developing new medical services using high-priced medical equipment, medicines and medical supplies which were not covered by medical insurance system rather than reduced running costs. Materials and Methods: This study was made to analyze and forecast the revenue change of the department of Obstetrics and gynecology of an university hospital in Seoul, expecting the implementation of DRG system in 2000. Results: The results were as follows : 1.During the first two days of hospitalization. 41% of total medical service fee was occurred, which was thought that most of the check-ups and operations were made during this period. After two days of hospitalization, the new occurrence of medical service fee tended to reduce. 2.Out of total medical service fee, 67% of admission fee was occurred after 5 days of hospitalization. This was because medical service fees in obstetrics and gynecology department occurred during the first 5 days of hospitalization. 3.Out of fees for operation, treatment, medical supplies and blood transfusion. 71% was occurred during the first two days. 4. In case of fees for examination, 50% was occurred during the first two days. 5.A total of 53% of fees for medication and injection was occurred during the first 5 days. Conclusions: By the implementation of the DRG system, the income is forecast to increase by 800 won to 310,000 won by the disease group of obstetrics and gynecology department. To increase hospital income with the implementation of DRG system, the results of this study suggest that examinations should be done at out-patient departments before the hospitalization of patient, the discharge of patient should be noticed in advance to reduce the period of hospitalization, and admission appointment system should be implemented for the immediate operation and delivery.

As mentioned above, I have acquired some valuable results about medical treatment with acupuncture and Moxibustion of " Flank pain" after studying oriental medical books . The results Were like below: 1. Medical treatment with acupunctures of Flank pain belonged to the Urinary Bladder Meridian of Foot Taiyang, the Liver Meridian of Foot Jueyin, the Gall Bladder Meridian of Foot Shaoyang. 2. Medical treatmcnt with acupunctures of Flank pain used to Yang-laung-chan(陽陵泉), Gi-gu(支溝), Gi-mun(期門), Kan-su(肝兪) in turn. 3. Medical treatment with Ear acupunctures of Flank pain used to Dam(膽), Sin-Mun(神門), Gan(肝)in turn 4. Acupuncture point of Flank pain were lowrer limb part. chest and abdominal part, back part in turn. 5. Medical treatment with Moxibustion of Flank pain was the most Jang-mun(章門)

In the present study, we aimed. to consider the name of twelve main Meridian in order to understand the concept of the Meridian system and to applicate acupuncture theory in the clinical field properly and fundamentally. We referred to several literatures on the matter and we found out that the name of present twelve Meridian was not settled until the period of Yellow Emperor's Classic. In the time of Yellow Emperor's Classic, the two theory of Internal Organ and Meridian system were combined and added new theory of 'WoonGi'. The general rule of combination is that the component of name of Meridian consist of 'Hand' or 'Foot', 'three Eum and Yang' and internal organ. The internal organ coupled with the root ki or middle ki of 'three Eum and Yang' and the 'Hand' or 'Foot' depend on the location of internal organ that belongs to meridian. The name of Twelve Meridian is a kind of system formed to analyze the two concepts organically and dynamically. One is material internal organ and the other is immaterial meridian system.

We propose an adaptive Tabu search method changing neighbor solution's range to be searched each iteration according to an objective function and design a PI controller using the proposed Tabu search. We apply it to a time-delay system to evaluate the usefulness of the proposed method. overshoot, rising time, and settling time.
