본 연구는 현재 지상파 DMB의 방송자막에 대한 사용자들의 인식을 파악하여, 향후 방송자막 디자인 개선 방향을 제시하고자 하였다. 먼저 방송자막에 대한 기존 연구들을 고찰하였다. 그 결과 프로그램 시청 시 방송자막이 중요한 역할을 하며, 글자 수의 최소화, 명료성을 높이는 글자체와 색상의 배열, 구성 요소의 재배치가 방송자막의 가독성을 높이는 주요 요소로 파악되었다. 그러나 실제 지상파 DMB 사용자들을 대상으로 설문 조사를 한 결과 화질, 화면 구성, 색상 및 명암 등에서 긍정적인 평가가 낮았다. 또한 방송자막의 가독성, 정보의 전달, 자막 구성, 글자체, 글자 수 및 글자 크기 등의 평가에서는 더욱 부정적인 것으로 나타났다. 앞으로 방송자막 형태 및 구성, 정보량의 제한, 글자의 선명성 및 크기, 색상 배치 및 선명성 등에서 지상파 DMB 화면에 적합하고, 사용자의 편이성을 고려한 자막 디자인의 개발이 절실히 요청된다. This research aimed at providing the direction for future improvement of broadcast subtitle design by identifying the user perception on broadcast subtitles of Terrestrial DMB. First, we contemplated on the existing research about broadcast subtitles. As a result, we found out that broadcast subtitle plays an essential role when watching a program and that the minimization of letters, clear fonts and color arrangement, rearrangement of components were identified as main factors that increase readability. However, the terrestrial DMB user evaluation on image quality, composition, color and brightness was not that positive. In addition, the evaluation on the readability of broadcast subtitle, information transmission, subtitle composition, letter font, number and size of letter was more negative. Developing a subtitle design which considers user convenience and suits terrestrial DMB screens in aspects of broadcast subtitle form and composition, limit of information, clearness and size of the letter is required.

This trial was objected to study about the effect of harvesting stage and nitrogen application level on the yield and chemical component of rye grown on paddy field, and the effect of harvesting stage and pre-wilting on the quality of the rye silage. It was conducted from October 1977 to June 1978 and the obtained results are summarized as follows. 1.Both fresh weight and dry matter yield were increased with high significance as the harvesting date was delayed. 2.As the nitrogen fertilizing level raised, fresh weight and dry matter yield were increased with high significance. 3.Concerned with the dry matter yield between different nitrogen level within a harvesting stage, there were no significant difference between treatment at April 21s1, significant. (P≤0.05) difference between treatment 1 and 3at May 1st and between treatment 1 and 2at May 11 th, and highly significant (P≤0.01) difference between treatment 1 and 3 at May 11 th. 4.As the harvesting stage delayed, the crude protein content of fresh herbage decreased and crude fiber increased. 5.The quality of silage made from all treatment were good except one made from the treatment harvested at May 1st and pre-wilted, which was cut coarsely with a straw cutter instead of an ordinary silage chopper due to electrical stoppage. 6.The content of lactic acid and NH3-N were decreased and pH increased as the maturity of material progressed. 7.It should be paid more attention to good chopping of the material than any other factor, to make good silage with rye.

The clavicle begins to ossify before any other bone in the body, it is ossified from 3 centers : two primary centers which appear during the fifth or sixth week of fetal life and become gradually curved secondary center for the sternal end, which appears in about the eighteenth or twentieth year. There are some investigation about the crystallization of the salts in bone, and thr calcification which have been carried out by Flecker, Hendriks, Bourne, Kodama and Te raoka. However, no detailed data on this subject in Korean has been reported as yet, an attempt is made to observe weekly the morphological development of the clavicle and to measure monthly its Ca & P contents in Korean fetus. Summary: 1. The maximum length of the calvicle the curvature index, and the contents of Ca & P in each week of fetal life in Korean are measured. 2. Graphically the growth of maximum length of clavicle tends to be straight line and curvature index increases more rapidly, they have a direct correlative relationship. 3. The contents of Ca & P in clavicle gradually increase during the early fetal life, and increase repidly during the second trimeter and become gradual again after then. 4. Ratio of P & Ca decrease during the late fetal life. 5. Therelis a direct correlative relationship between the maximum length and the contents of P & Ca in clavicle and between the contents of P & Ca.

Although there are many methods for the investigation of the ossification in fetus. Roen tgenographic method has been enployed by Hass and others, because of the simplicity of its procedure and the auailability of the tissue for the subsequent histological examination. Now this method are considered more important since Hodge found that much greater refinement has been achieved and correct observation can be doneby impregnation heavy metal salts. Leslie, Haas, Handy, I eopold, Yoshimura and Kunitomo carried out detailed works on the growth of fetal C-R Iength correlative relation between the C-R length and the growth of long bone is important not only in the ontogenetical viewpoint but also in the clinical view-point. Zwisch and Koyama reported their works on this subject but there are few works on this subject in Korea. The summary of this investigation is follows; 1. The C-R length and maximum length of long bone in the 103 Korean fetus are measured and the mean-value and correlation-ration are obtained. 2. Graphically the growth of C-R length in the first trimester of fetal life is straight line. Its growth rate become slightly more rapid in the 2nd trimester and slowere in the last trimester. The long bone growth slowly throughout the fetal life. 3. The femur is smaller than the Humerus until the 13th week of fetal life and becomes equal from the 14th week and larger after the 20the week. 4. The Tibia is smaller than the Humerus until the 29th week. 5. There is direct correlative relationship between the growth of the C-R length and ong bone, and between the growth of the uhper and lower extremity.

When it is certain that the paralysis could not be recovered in a injured patient acomp. anying the nerve paralysis, and that there is no other curative method to the injured nerve itself, the most necessary treatment seems to be the tendon transplantation in which the paralyzed function of the tendon is compensated by a normal tendon. 1. A tendon tran transplantation has been perfomed on 5 patients who had radial nerve paralysis and on 3 patients who had medial and ulnar nerve paralysis. 2. By addition of modified procedure to the Hohmann's original method for the treatment of the patient who had radial nerve paralysis, it was found that the grasping power and motion limit of wrist joint increase in 3 weebs. 3. The splint should be used for more than a month to support the wrist joint.

各種物質에 對한 Metacercaria의 抵抗力 : RESISTANCE OF THE METACERCARIA AGAINST VARIOUS SUBSTANCE

李城寬,李光直 慶北大學校 醫科大學 1958 慶北醫大誌 Vol.1 No.1

Since the liver distoma is caused by ingestion of the raw fresh water fish, determination of the resistance of the metacercariae present in those fishes is an important subject. Because Koreans use special seasonings in their cooking. The resistance of the metacercaria against several seasonings as well as other drugs has been determined. 1) Among the seasonings the metacercariae have the least resistance against garlic. They became immobile within 10 minutes in the filtrate of 1.0 gm of garlic in 1.0㏄. of water. 2) The metacercariae are quite resistant in the low temperature. They could survive for 40 hours in the temperature of 2℃ below zero and for 34 days in 2℃. However, they became immobile within one minute in the temperature above 55℃. 3) Among the antiprotozoas the metacercariae have a relatively weak resistance against Quinine and Atabrin but they are quite resistant against antibiotics such as streptomycin and Penicillin. 4) Among the drugs commonly used for the treatment of clonorchis the metacercariae have a weak resistance against Gentiana-Violot and Emetin but they are quite resistant against Antimon derivatives.
