Carcinoma ex pleomorphic adenoma is transformed at the incidence of 1-20% in pleomorphic adenoma and frequently recurred. It accounts for 10% of all malignant salivary tumors and its average age of occurrence is 60s. It will present in a large, long-standing pleomorphic adenoma or in one that was previously treated but has recurred. According to cell composition in malignant cell carcinoma, and clear cell adenocarcinoma. Most (75%) occur in parotid gland, while about 20% occur in the minor gland of the oral mucosa. The metastasis rate to regional lymph node is about 25%, and to distant organs about 33% and the 5-year survival rates are 40%. Though the treatment of the carcinoma ex pleomorphic adenoma is not established, it is treated ideally with and extensive resection, neck dissection, postoperative radiotherapy, and chemotherapy. When occurred in parotid gland, facial paralysis is reported. With a review of literatures, we report a case of carcinoma ex pleomorphic adenoma which operated with total parotidectomy and supraomohyoid neck dissection.

가셑판이 면외 용접된 인장부재의 피로에 관한 연구

정진환,박종진,김인태 釜山大學校生産技術硏究所 1999 生産技術硏究所論文集 Vol.56 No.-

인장부재와 휨부재의 복부판 및 플랜지에 가�V판이 면외 용접되었을 경우, 용접단부에서 높은 응력 집중현상이 유발되어, 피로강도를 저하시키는 원인이 된다. 인장부재와 가�V이 면내 용접연결 되어 있을 경우, 피로 균열을 방지하기 위한 각종 규정이 명시되어있지만 가�V이 면외 용접된 경우는 시방서 기준이 미비한 상태이다. 본 연구에서는 가�V판이 면외 용접된 인장부재 및 힘부재의 피로시험을 수행하여 그 결과들을 분석하였다. 시험체에 용접된 가�V의 길이 및 용접단부의 마무리 유무에 의한 피로수명의 차이도 검토하였으며 각종 피로 설계 규정과 비교, 검토하였다. The fatigue performance of tension and beam members with out-of-plane gusset plates is decreased due to the stress concentration at the weld toes. In order to improve the fatigue performance, design manuals provide specifications for the members with in-plane gusset plates. However, design sepcifications are not available for the members with out-of-plane gusset plates. In this study, series of fatigue tests are carried out on the tension and beam specimens with out-of-plane gusset plates. The tests are also peformed by varying such factors as width of the gusset plates and smoothing of the weld toes. The results are compared with the provisions specified in the existing design manuals.

Ⅰ. Introduction In consideration of the police system of each country at the present times it is the general convention to divide the police administration into two different parts such as the aspect of national interests and that of local interests, and then further classify it, ell the basis of its source of control, into the national and local police organizations. The former is termed the continental-law police system, while the latter is referred to as Anglo-American style police system. This study provides a review of the continental-law police system as practiced by those European countries including Germany, France, Denmark, Sweden, and Switzerland, a system which has influenced ours since 1894 Reformation (= Gab-O Kyungchang) and which Japan has also once adopted in imitation. It also includes a brief glimpse of the general advantages and disadvantages accompanied by the police system of the above mentioned continental-law countries. Finally this study has attempted to present an analysis of our own police system which has largely derived from and further developed the continental-law police system, while endeavoring to determine the prospective direction of its future development. Ⅱ. The Police Systems in the Continental-law Countries 1. Germ any 1) With the corning of the National Socialists in 1933 a considerable reorganization of the police fort·cert took place. Germany became a unitary State and the Lander Governments lost their powers, including control of their Police forces. A National system of police was created under the Reich Minister of the Interior and in 1936 a new official-the Chief of the German Police-was appointed under him, but with powers to issue ministerial decrees on police matters. 2) After the World War II, the four Occupation Powers-United States, Great Britain, U.S.S.R. and France tried to introduce their own ideas of police organization into their respective Zones. 3) In September 1949 the Council of the Allied High Commission issued a letter of instruction to Land Commissioners respecting the organization, control and administration of police within their Lander (State). The functions of the police were outlined and these included the maintenance of public order and safety, prevention of crime and bringing offenders to justice. The organization of police was to be decentralized below the Land level unless specific apple·oval for land police had been given by the High Commission. 2. France 1) The French Minister of the Interior is responsible for the safety of persons and property, for the maintenance of public order and for the security of the state. 2) To carry out these duties he has three police forces at his disposal. They are : (1) The Pre´fecture of Police, covering the Seine Department (Paris itself and eighty neighbouring Communes), comprising some twenty-three thousand officers and men ; (2) The National Gendarmerie, covering all the Departments of France, comprising about sixty-three thousand officers and men ; and (3) The Su^rete´ Nationale-a National Police Force-covering all the Departments of France and totalling about fifty-three thousand officers and men. 3. Denmark 1) The Danish Police Force is a State organization. All members are appointed by the State and all expenses for the Force are defrayed by the State. 2) In Denmark the Police Force is under the control of the Ministry of Justice, and it has the duty of maintaining order, combating crime, prosecution tasks and Civil Defence. The Force also has much more responsibilities than that of other countries in Europe. 3) A central police administration was established in 1938 under the direction of a Commissioner of Police ('Rigspolitichefen') but in principle essential characteristics from the former general organization of the police still remain. The local cheif constables (seveny-two) are still the independent commanders of the personnel placed at their disposal by the Commissioner of Police on behalf of the State. 4. Sweden 1) From ancient times the policing systems in Sweden have always been based on the individual communes. 2) With the passage of centuries, however, the Central Government gradually exerted more and more influence in matters of police-control and the present organization of the Swedish police is regulated by a law passed in 1925 and 1965. 3) And now the Swedish police is completely a national police system. In the ministry of Justice the National Police committee has been organized and the police administration is executed by the National Police Bureau. Every local goverment district (La¨n) equivalent to English counties, which are sub-divided into about 119 commues has its own district police division. 5. Switzerland 1) The Federation is composed of nineteen full cantons and six half-cantons. The Federal Constitution gives some powers to the Federation and others to the Cantons. Thus, except for certain minor offences and administrative and fiscal criminal infractions the right to legislate on criminal matters is reserved by the federation Parliament. 2) Poice duties are shared by the Cantons and the Federation, although the greater part of these duties falls on the former. In addition to the Administrative Service the Federation has a small police force-the Federal Police-which constitues one of the services of the Federal Department of the Public Prosecutor. In Switzerland, therefore, in addition to the federal Police, there are the twenty-five police forces of the cantons and half-cantons and a number of separate Municipal Police Forces. Ⅲ. Advantages and Disadvantages of the police systems adopted by continental-law countries. 1. Advantages 1) Reinforced by the power of the rotate, this system makes it possible for the police to exercise potent and extensive capabilities of execution. 2) Under this system it is feasible to maintain close working-relationship withother ministries and agencies of the government and in case of emergency the system itself facilitates police activities. 3) This system, enabling the police to take prompt actions anytime, anywhere throughout the counts·y, is better adopted to criminal investigation. 4) This system is considered more favorable in the light of personnel management and training of the police force, as well as the supply of police equipment. 5) This system can effectively exclude possible interference by local politicians or any other pressure groups. 2. Disadvantages 1) It is easy under this system to impose on the police some special tasks which may be connected with executive duties but do not fall in the category of regular police mission. 2) Under this sytem the police are apt to assume a bureaucratic attitute and create a coercive atmosphere for the people. 3) Practice of nation-wide police regulations throughout the country may possibly prove unsuitable to some localities. 4) It is likely that the morale or efficiency of the local police remains low and particular activities for local population fall into sluggishness. 5) Under this system, each individual police officer is often believed to have only a tenuous feeling that he is a public servant. Ⅳ. The police system in Korea 1) Ours is one which has been patterned after the continental-law police system, especially that of Germany, since the 1894 Reformation. 2) Our police system has been in complete alignment with the nation's administrative mechanism as a whole, with its highly centralized structure. 3) No consideration is given to any autonomous operation of our police system, The local police are carrying out nothing but such things as are consigned by the national government. 4) With the introduction of corporation police and security service system, we have supplemented our police system by sore of the advantages of the Anglo-American law. 5) The basic mission of our police, as far as the academic theory goes, is known to be limited to the maintenance of law and order after the fashion of Anglo-American system. Ⅴ. Conclusion 1) The two police systems of continental and Anglo-American laws have disadvantages as well as advantages. 2) Therefore, the decision as to which one of the two is preferable will he based on the following factors; - a. the general administrative structure b. traditional traits of the people c. the level of development in transportation and communication d. rotate of public safety 3) It may reasonably be said that the continental-law police system is more desirable when the nation's situation requires a strong police mobility whereas Anglo-American law system seems more advantageous when the nation attaches importance to the protection of human lives and property of individual citizens. 4) In view of the national and international situation facing the nation at present, we feel it at to have adopted the continental-law police system. For the sake of democratic development, however, means and methods should be sought after to have it strengthened by various advantages of the Anglo-American law system in the future.

Platycodon root contains abundant pharmaceutical substances and is widely used as a food and a medicinal herb. To identify the major components of the three-year-old and the 24-year-old platycodon roots cultivated in a local farm were analyzed and compared with their chemical compositions prior to their pharmaceutical substances, which were used as the fundamental data. There were no differences in chemical composition, inorganic compositions and fatty acid compositions between the 24-year-old and three-year-old roots. Total amino acid contents were 375.8 ㎎% and 891.6 ㎎% in the 24-year-old and three-year-old platycodcon roots, respectively. Sixteen species of amino acid were identified by amino acid autolyzer except cysteine both in the 24-year-old and three-year-old roots. Linoleic acid, which was the highest fatty acid contained both in the 24-year-old and three-year-old roots, was estimated to be 48.7% and 39.1% of total fatty acids, respectively.
