The purpose of this experiment is an experimental study on recycling of waste concrete and suggest a possibility of the Recycled Aggregate Concrete after establishing some kinds of experimental properties of concrete. Therefore, this study compared and investigated properties of natural aggregate concrete and recycled aggregate concrete by replacing the ratio of recycled aggregates under the absorptions, compressive strengths and chemical resistances. As the result, the compressive strength and the chemical resistance of Recycled Aggregate Concrete is lower than the natural aggregate concrete. If was concluded that the properties of the recycled aggregates and lower than natural aggregates.

Visual evoked potentials were elicited by flash in 29 patients with a variety of cerebral lesions and in 10 normal controls. In 12 patients with focal brain lesions, no wave form could be recorded in one side. Of the remaining 23 sides, the average P₁ latency showed no difference from that of the normal controls. In 17 patients with diffuse brain lesions no wave form could be elicited in 12 sides. Average P₁ latency of remaining 22 sides showed statistically significant difference from that of normal controls. In this study it appears that delayed P₁ latencies are associated with diffuse cerebral lesions rather than with localized lesions.

本 硏究는 不景氣를 맞이한 스칸디나비안 항공사(SAS)를 事例로 하여, 그들의 企業經營回復을 體係的으로 分析한 事例硏究이다. 이 業例는 原價節減方式이 아닌, 組織의 變化와 人間關係中心의 經營方式에 중점을 둔 經營回復의 내용으로서 우리는 이를 통하여 動的組織(Dynamic organization)과 從業員中心(Labor-managed)의 經營이 단순히 費用節減만을 추구하는 경영방식보다 有效하다는 것을 立證해 볼 수 있다. This case study is on the corporate recovery of Scandinavian Airline System(SAS) suffering from business depression for years. This study lays its focus not in cost management, but in organizational change and HR oriented management system for the recovery of business. Through the case study, we can find that dynamic organization and labor-oriented management show more effective performances than simply cost-controlling management. This will be divided into four sections. Part I will give the reader a brief history of SAS, and introduction to problem definition. Part II will deal with SAS up to until the time of the crisis. Discussed will be the earlier market, the organizational structure and the problems which led up to the need of the reorganization. Part III will look at the actual reorganization taking into account the change in management philosophies, structure and their effects. Part IV will summarize the results of the reorganization as well as discuss some aspects of the future for SAS.

This reaearch aims at the development of the scenarios leading the activation of the Korea Red China Relations and the cost-down in transportation at the aspect of flight system, with the charting of the airways, under the growing interest of the world nations in East and Pacific. Researchers took the planning and decision making model using scenarios, which composed of multi-subsystems: system objective, data base, organizational variables, environmental variables, and review sector. After researching the various concerned information, authors drew up the following air routes, as conclusions.

The purpose of this study is to propose the pertinent plan for crack through analyzing types, styles, periods, parts and features of crack for national concrete-related pursuers in domestic working site. And this is a basic study on control of crack which is presented to reinforced concrete structure. For these purposes, as we make check-list about each cause of crack and eliminate the cause of crack in first place in job site, we can make an effective method of control the crack as a whole.

Thyroglossal duct cyst is the most common developmental anomaly of the thyroid and the second most common pathology among childhood cervical masses. They present non-tender palpable mass on midline neck, and they are usually asymptomatic. The cysts are usually benign, but one percent of cases is associated with malignancy. From the world literature, 115 cases of malignant thyroglossal duct cyst are available for review. Despite aspiration cytology and the radiologic images, malignant thyroglossal duct cysts are usually comfirmed after surgery. The authors experienced a case of papillary carcinoma arising from the thryroglossal duct cyst without evidence of local invasion.

A case of cystic acoustic Neurinoma is reported. The Patient was 41 year old man with temporal lobe epilepsy. Computerized tomography disclosed a low density cystic mass at left cerebellopontine angle that extended to suprasellar cistern through tentorium. At operation, multiloculated cysts were found that looked like cysticercosis. Pathological examination revealed a typical neurilemmoma with Antoni A and B area that formed cyst wall.

Medicinal Precipitated Clacium Carbonate is prepared by the interaction of Calcium Chloride and Ammonium Carbonate Solutions in this study. It has been known that the particle size of Precipitated Calcium Carbonate is greatly affected by the concentration, temperature, and moli-ratio of reactant solutions as well as the temperature at which the precipitate is dried and the temperature of washing water. The purpose of this study is to determine the optimum preparation Condition of medicinal Precipitated Calcium Carbonate. A randomized complete block design wuggested by G.E.P. Box and K.B.Wilson was for this purpose. The optimum preparation condition of light and fine precipitated Calcium Carbonate obtained from this study is as follows : 1) The reacting temperature range is 25∼45℃ 2) The concentration range of reactant solutions is 10∼30% 3) The optimum mole-ratio (CaCl/(NH) CO) is 1.0∼2.0. 4) The drying temperature range is 60∼80℃. 5) Temperature range of washing water is 25∼60℃.

This is a research report of the research that led to the opening of a population education course at Ewha Womans University. The research itself may be divided into the following four parts: planning for the research ; preparatory work for a population education course; opening of a population course; and evaluation of the population course. In the first stage of the research, the work, as usual, consisted of organizing the research team, setting up the research objectives, planning the research schedule, etc. The project began in the Fall of 1974, and concluded in the Fall of 1978. In the second stage of the research, the work was carried out for the preparation of a course in population education. Several sessions of faculty conference, in which more than 40 professors from various fields of specialization participated, were held in order to determine the specific objectives of the proposed course, to draw up a syllabus, and to prepare for a textbook for the course. When a rough sketch of the syllabus, and the contents of the course was made a student group was organized to examine and evaluate it. In the third stage of the research, a population education course titled "Population and Future" was opened as an elective course in the general education curriculum. This was in the Fall of 1875, and the course remained open every semester until now. An anthology with the same title as the course itself was used for reading, and the teaching was carried out as a team teaching by a team of 6-9 professors. In the fourth stage of the research, an evaluative study was taken up in order to evaluate the course with regard to its structure, textbook, teaching method, and its contents, as well as to assess the effectiveness of the course on terms of the students' change in their cognitive and emotive or attitudinal response to population problem.
