We described three cases of immediate reimplantation of a frozen-thawed autogenous mandible composed of a mixture of iliac bone, marrow, and particulate hydroxyapatite in tumors of the mandible. Acceptable outcomes were obtained in three patients who underwent immediate autogenous mandibular graft reconstruction. The conditions leading to successful outcome of the procedure are also discussed. Reimplantation of frozen autogenous lesioned mandible was performed in three patients with mandibular tumors. Two reimplanted grafts survived without complications following surgery. One case had postoperative infection that resolved with appropriate antibiotic treatment. There were no recurrences of the primary lesions. Satisfactory facial contour after surgery was achieved. These results are most promising, and we believe that, with further refinement, this technique will offer a new and acceptable modality for facial reconstruction in patients with cancer.

Soo‑Bae Kim,Young‑Hee Cho,Jae‑Gil Jung,Woon‑Ha Yoon,Young‑Kook Lee,Jung‑Moo Lee 대한금속·재료학회 2018 METALS AND MATERIALS International Vol.24 No.6

Ultrasonic melt treatment (UST) was applied to an A390 hypereutectic Al–Si alloy in a temperature range of 750–800 °Cand its influence on the solidification structure and the consequent increase in strength was investigated. UST at such a hightemperature, which is about 100 °C above the liquidus temperature, had little effect on the grain refinement but enhanced thehomogeneity of the microstructure with the uniform distribution of constituent phases (e.g. primary Si, α-Al and intermetallics)significantly refined. With the microstructural homogeneity, quantitative analysis confirmed that UST was found tosuppress the formation of Cu-bearing phases, i.e., Q-Al5Cu2Mg8Si6, Al2Cuphases that form in the final stage of solidificationwhile notably increasing the average Cu contents in the matrix from 1.29 to 2.06 wt%. A tensile test exhibits an increasein the yield strength of the as-cast alloy from 185 to 208 MPa, which is mainly associated with the solute increment withinthe matrix. The important role of UST in the microstructure evolution during solidification is discussed and the mechanismcovering the microstructure-strengthening interrelationship of the ultrasonically treated A390 alloy is proposed.

The effect of ultrasonic melt treatment (UST) on the solidification microstructure of an Al–5Ti–1B alloy containing highvolumefractions of Al3Tiand TiB2particles is investigated for various UST times with different melt holding times. Theas-cast Al–5Ti–1B alloy is composed of TiB2and polygonal Al3Tiparticles (present prior to UST), plate-like Al3Tiparticles,and Al grains (formed during UST and/or solidification). The UST causes a size reduction and homogeneous distributionof the TiB2-agglomerated region containing many submicron-sized TiB2particles pushed to the grain boundaries. The USTslightly decreases the size and improves the distribution of polygonal Al3Tiparticles enriched in the TiB2-agglomeratedregion. Unlike the TiB2and polygonal Al3Tiparticles, which exhibit a minor refining effect, the plate-like Al3Tiparticlesshow a significant refinement with UST application. The UST has a significant effect on the size distribution of Al grains byinducing the formation of medium-sized grains at the expense of small and large grains; however, it only has a slight effecton grain refinement. The degree of microstructure modification increases with increasing UST time but decreases with meltholding time after UST. The mechanisms for the refinement and dispersion of the TiB2and Al3Tiparticles and Al grains arediscussed considering fragmentation, nucleation, and growth behaviors induced by the UST and subsequent solidification.

『오델로』의 劇構造에 나타난 이성과 직관

김길수 현대영미어문학회 1999 현대영미어문학 Vol.16 No.2

In point of substance, and in point of style, the likeness of Othello to Hamlet is much greater than the likeness; there is a probability that Othello was the tragedy written next after Hamlet. And also that it is confirmed by similarities of style, diction and versification, and also by the fact that Ideas and phrases of the earlier play are echoed in the later. There is a certain resemblance in the subject Accordingly Othello is the most painfully exciting and most terrible. From the moment when the temptation of the hero begins, our heart and mind are held in a vice, experiencing the extremes of pity and fear. Sympathy and repulsion, dreadful expectation if the simple issue is shaped by the play's structure into the form of a struggle to the death between Good and Evil, then such matters are dearly not so much 'simple' as fundamental. It is this kind of structural simplicity. Accordingly the events of the plot are taxed from the very beginning with the weight of something ulterior. Iago represents Evil, Desdemona does simply Good, and also Othello is forced to choose between the two, such an uncompromising structure must be the basis of any analysis of the play, and it ensures that the play's action concerns itself primarily with Othello's choice. The fact that such choice faces him comes about largely as a result of what Iago says and does in the play. The choice itself is manufactured and offered to Othello by Iago, the decision in the matter reached by Othello and the action he takes are conditioned and controlled by Iago, Desdemona throughout is a passive entity; she is there, but no action comes from her. All action is done to her with the climax of the tragic action of the murder.

The purpose of this paper is to investigate and analyze the nation's consciousness about the social physical education by regional groups(big cityes, middle cityes, farm village, fishing villge). And the researchers are to find a way to populize this movement. These subjects for this investigation were chosen at random among the citizens in four region. 4,450 sheets of questionnaire were given to the citizen. And 3,587(81%) sheets of them were received from male(2,582) and female(975) citizens. The results of this investigation are as follows: 1. The nation's consciousness has not been still modernized and the nation tend to depend on their doctors rather than on the new active leisure sports, which is a passive and conventional way, to keep their health. 2. Most people have spent their leisures on nonactive hobby such as reading, listening to music, and watching TV rather than sports. 3. Most residents pointed out lack of facilities, and needed professional directors and various programs they could participate. 4. The opening of citizen athletic field and the gymnasiums to citizens was needed to recruit the lack of facility, and the participation to commercial sport ws differed by economical status and leisure time, however, they usually participated such activities as table-tennis, swimning and tennis. 5. To activate social physical education, first of all, an expansion of the facilities such as athletic fields and gymnasium is needed under the active support of government. 6. The facilities for young men and the handicapped is insufficient, and to prevent juvenile delinquency and guide them into the right way, we should lead them out to participate sports activity. And the facility for the handicapped is needed too.

金秀吉 제주대학교 1983 논문집 Vol.16 No.2

This study was conducted to consider a counter-measure to meet Korea public official's crime through the analysis and investigation of its general situation and factors. In Korea, a certain specified factor does not exert influence on the occurance of the public official's crime; rather, various factors(politic, economic, socia1, and cultural ones including the problems of remuneration and administrative control) jointly exercise effects upon it. Therefore, in order to prevent the public official's crime the government has to consider a reasonable, long-term counter-measure which can remove various, direct or indirect factos affecting the occurence of public official's crime. The counter-measure to cope with the crime of Korean public official is as follows: 1. Public officials have to reform their prevented their views of public duty and establish their democratic views of public servant by themselves. 2. Politic corruption must be prevented, and politic stability established, too. 3. The governmment must pay public officials more amount than mminimum cost of living as salary and improve reasonably its annuity system. In addition, the government must rationalize personnel management system and intensify education and training for improving the qualities of the whole civil servants. 4. Economic balance and stability must be established. 5. The whole people have to establish sound social climate through the enhancement of their sense of value and their spirit of obeying laws. 6. The government has to make its best to prevent the occurence of its official's crime, and the public official who commit crime must be punished in strict fairness.
